Table of Contents

Statements we make in this Annual Report on Form 10-K, which express a belief, expectation or intention, as well as those that are not historical fact, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to various risks, uncertainties and assumptions, including those to which we refer under the headings "Cautionary Statement Concerning Forward-Looking Statements" and "Risk Factors" in Items 1 and 1A of Part I of this report. In this Annual Report on Form 10-K, unless the context otherwise indicates, "we," "us" and "our" mean BWX Technologies, Inc. ("BWXT" or the "Company") and its consolidated subsidiaries.

PART I


Item 1.	BUSINESS

General

BWX Technologies, Inc. ("BWXT" or the "Company") is a specialty manufacturer of nuclear components and a service provider with an operating history of more than 100 years. Our core businesses focus on the design, engineering and manufacture of precision naval nuclear components, reactors and nuclear fuel for the U.S. Government. We also provide uranium processing and environmental site restoration services, as well as a variety of products and services to customers in the nuclear power industry. While we provide a wide range of products and services, our business segments are heavily focused on major projects. At any given time, a relatively small number of projects can represent a significant part of our operations.

Prior to June 30, 2015, we completed an internal restructuring that reorganized the subsidiaries involved in our former Power Generation business and established BWE as the direct or indirect parent company of all those subsidiaries. The results of operations of our former Power Generation business are presented as discontinued operations on the consolidated statements of income. We have presented the notes to our consolidated financial statements on the basis of continuing operations, unless otherwise stated.

Business Segments

We operate in three reportable segments: Nuclear Operations, Technical Services and Nuclear Energy. Prior to 2015, our mPower business was a separate reportable segment and is now included in our "Other" category.

For financial information regarding each of our segments, financial information regarding geographic areas and additional information regarding the change to our segments, see Note 17 to our consolidated financial statements included in this report. For further details regarding each segment’s facilities, see Item 2, "Properties." In general, we operate in capital-intensive industries and rely on large contracts for a substantial amount of our revenues. We are currently exploring growth strategies across our segments through acquisitions to expand and complement our existing businesses. We would expect to fund these opportunities with cash on hand or by raising additional capital through debt, equity or some combination thereof.

Nuclear Operations

Through this segment, we engineer, design and manufacture precision naval nuclear components and reactors for the U.S. Department of Energy ("DOE")/National Nuclear Security Administration’s ("NNSA") Naval Nuclear Propulsion Program. In addition, we perform development and fabrication activities for submarine missile launch tubes for the U.S. Navy.

Our Nuclear Operations segment specializes in the design and manufacture of close-tolerance and high-quality equipment for nuclear applications. In addition, we are a leading manufacturer of critical nuclear components, fuels and assemblies for government and limited other uses. We have supplied nuclear components for DOE programs since the 1950s and are the largest domestic supplier of research reactor fuel elements for colleges, universities and national laboratories. We also convert or downblend high-enriched uranium into low-enriched fuel for use in commercial reactors to generate electricity. In addition, we have over 100 years of experience in supplying components for defense applications.

Table of Contents

We work closely with the DOE-supported nuclear non-proliferation program. Currently, this program is assisting in the development of a high-density, low-enriched uranium fuel required for high-enriched uranium test reactor conversions. We have also been a leader in the receipt, storage, characterization, dissolution, recovery and purification of a variety of uranium-bearing materials. All phases of uranium downblending and uranium recovery are performed at our Lynchburg, Virginia and Erwin, Tennessee sites.

The demand for nuclear components by the U.S. Government determines a substantial portion of this segment's backlog. We expect that orders for nuclear components will continue to be a significant part of backlog for the foreseeable future. In addition, this segment could benefit if the U.S. Government implements recommendations by the the U.S. Navy to increase the size of its fleet of ships to include additional submarines and/or aircraft carriers beyond the number included in the U.S. Navy's fiscal year 2016 long-range shipbuilding plan issued on April 3, 2015.

Technical Services

Through this segment, we provide various services to the U.S. Government, including uranium processing, environmental site restoration services and management and operating services for various U.S. Government-owned facilities. These services are provided primarily to the DOE including the NNSA, the Office of Nuclear Energy, the Office of Science, and the Office of Environmental Management; the Department of Defense and the National Aeronautics and Space Administration ("NASA").

This segment’s principal operations include:


•	managing and operating nuclear weapons production facilities;


•	managing and operating environmental management sites;


•	managing spent nuclear fuel and transuranic waste for the DOE;


•	providing critical skills and resources for DOE sites; and


•	managing and operating space flight hardware and test facilities for NASA.

Our Technical Services segment’s overall activity primarily depends on authorized spending levels of the DOE including the NNSA, the Office of Nuclear Energy, the Office of Science, and the Office of Environmental Management; the Department of Defense and NASA. We manage and operate complex, high-consequence nuclear and national security operations for the DOE and the NNSA, primarily through our joint ventures, as further discussed under the caption "Joint Ventures" below.

Nuclear Energy

Through this segment, we design, license, manufacture and deliver commercial nuclear steam generators, pressure vessels, reactor components, heat exchangers and other auxiliary equipment, including containers for the storage of spent nuclear fuel and other high-level waste. This segment is also a significant supplier to nuclear power utilities undergoing major refurbishment projects and has supplied over 300 pressurized water reactor steam generators worldwide, as well as other critical plant components. In addition, this segment offers a full spectrum of services for steam generators and balance of plant equipment, as well as nondestructive examination and tooling/repair solutions for other plant systems and components. This segment also offers engineering and licensing services for new nuclear plant designs. Our in-depth knowledge comes from over 50 years of experience in the design, manufacturing, commissioning and service of nuclear power generation equipment.

This segment specializes in performing full scope, prototype design work coupled with manufacturing integration. The design, engineering and other capabilities of this segment include:


•	steam generation and separation equipment design and development;


•	thermal-hydraulic design of reactor plant components;


•	commercial nuclear fuel manufacturing and design;


•	nuclear fuel handling system design, manufacturing, delivery, installation and commissioning;


•	containers for the storage of spent nuclear fuel and other high-level waste;


•	heat exchanger structural and thermal-hydraulic design and vibration analysis;


•	structural component design for precision manufacturing;

Table of Contents


•	materials expertise in high-strength, low-alloy steels and nickel-based materials;


•	material procurement of tubing, forgings and weld wire; and


•	metallographic and chemical analysis.

Our Nuclear Energy segment’s overall activity primarily depends on the demand and competitiveness of nuclear energy. A significant portion of our Nuclear Energy segment’s operations depend on the timing of maintenance outages, primarily in the Canadian market, and the cyclical nature of capital expenditures and major refurbishments for nuclear utility customers, which could cause variability in our financial results.

Acquisitions

On December 16, 2016, our subsidiary BWXT Canada Ltd. acquired the outstanding stock of the GE Hitachi Nuclear Energy Canada Inc. ("GEH-C") joint venture for CAD 157.9 million ($117.8 million U.S. Dollar equivalent), subject to customary working capital, cash and debt adjustments, which was renamed BWXT Nuclear Energy Canada Inc. ("NEC"). NEC is a leading supplier of nuclear fuel, fuel handling systems, tooling delivery systems and replacement components for CANDU reactors and has approximately 350 employees. NEC operates two facilities licensed by the Canadian Nuclear Safety Commission ("CNSC") to fabricate natural uranium fuel in Peterborough and Toronto, Ontario, Canada as well as a third facility in Arnprior, Ontario, Canada. NEC expands our current commercial nuclear products and services portfolio and allows us to leverage our technology-based competencies in offering new products and services related to plant life extensions as well as the ongoing maintenance of nuclear power generation equipment and is reported within our Nuclear Energy segment.

For additional information on the acquisition of NEC, see Note 2 to our consolidated financial statements.

Special Charges for Restructuring Activities

In 2014, we began certain initiatives aimed at driving margin improvement in our Nuclear Energy segment’s operating model, which allowed us to achieve our target of a minimum 10% operating margin by the end of 2016. These programs were substantially complete as of June 30, 2015. In order to achieve these savings, we incurred total restructuring charges (cash and non-cash) of $0.7 million and $9.9 million in the years ended December 31, 2015 and 2014, respectively.

During the second quarter of 2014, we announced plans to restructure our mPower small modular reactor program to reduce spending and focus on technology development and subsequently slowed the pace of development. In the years ended December 31, 2015 and 2014, we incurred $15.9 million and $10.6 million, respectively, of costs associated with the restructuring.

In the year ended December 31, 2014, we incurred $0.4 million of costs associated with the restructuring of our Technical Services segment.

mPower Framework Agreement

On March 2, 2016, we entered into a framework agreement with Bechtel Power Corporation ("Bechtel"), BWXT Modular Reactors, LLC and BDC NexGen Power, LLC, our partner in Generation mPower LLC ("GmP"), for the potential restructuring and restart of our mPower small modular reactor program (the "Framework Agreement"). As a result of entering into the Framework Agreement, we have deconsolidated GmP from our financial statements as of the date of the Framework Agreement. We recorded a gain of approximately $13.6 million in the year ended December 31, 2016 related to the deconsolidation of GmP as a component of other – net in our consolidated statement of income. In addition, we also recorded a $30.0 million loss contingency pursuant to the terms of the Framework Agreement.

For additional information on the Framework Agreement, see Note 11 to our consolidated financial statements.

Dispositions

In the first quarter of 2014, we announced that we would exit our Nuclear Energy segment’s Nuclear Projects business as it had lower margins and higher financial risks. Run-off operations for remaining projects were completed during the second quarter of 2014. Income (loss) before provision for income taxes for the Nuclear Projects business was $(4.5) million in the year ended December 31, 2014.

Contracts

We execute our contracts through a variety of methods, including fixed-price incentive fee, cost-plus, target price cost incentive, cost-reimbursable, fixed-price or some combination of these methods. We generally recognize our contract revenues and related costs on a percentage-of-completion basis. Accordingly, we review contract price and cost estimates regularly as the work progresses and reflect adjustments in profit proportionate to the percentage of completion in the period when we revise those estimates. To the extent that these adjustments result in a reduction or an elimination of previously reported profits with respect to a project, we would recognize a charge against current earnings, which could be material.

We have contracts that extend beyond one year. Most of our long-term contracts have provisions for progress payments. We attempt to cover anticipated increases in labor, material and service costs of our long-term contracts either through an estimate of such changes, which is reflected in the original price, or through risk-sharing mechanisms, such as escalation or price adjustments for items such as labor and commodity prices.

In the event of a contract deferral or cancellation, we generally would be entitled to recover costs incurred, settlement expenses and profit on work completed prior to deferral or termination. Significant or numerous cancellations could adversely affect our business, financial condition, results of operations and cash flows.

For further specification, see "Risk Factors Related to Our Business – We are subject to risks associated with contractual pricing in our industries, including the risk that, if our actual costs exceed the costs we estimate on our fixed-price contracts, our profitability will decline, and we may suffer losses" as outlined in Item 1A of this report.

Nuclear Operations

The majority of the revenue generated by this segment is from long-term contracts with the DOE/NNSA’s Naval Nuclear Propulsion Program. Unless otherwise specified in a contract, allowable and allocable costs are billed to contracts with the U.S. Government in accordance with Federal Acquisition Regulation ("FAR") and the related U.S. Government Cost Accounting Standards ("CAS"). Examples of costs that may be incurred by us and not billable to the U.S. Government in accordance with the requirements of the FAR and CAS regulations include, but are not limited to, unallowable employee compensation and benefit costs, lobbying costs, interest, certain legal costs and charitable donations.

Most of our contracts in this segment are fixed-price incentive fee contracts which provide for reimbursement of allowable costs incurred plus a fee and generally require that we use our best efforts to accomplish the scope of the work within some specified time and stated dollar limitation. Fees can be fixed in terms of dollar value or percentage of costs. Award and incentive fees are determined and earned based on customer evaluation of our performance against negotiated criteria, primarily related to cost, and are intended to provide motivation for excellence in contract performance. Incentive fees that are based on cost provide for an initially negotiated fee to be adjusted later, typically using a formula to measure performance against the associated criteria, based on the relationship of total allowable costs to total target costs. Award and incentive fees that can reasonably be estimated and are deemed reasonably assured are recorded over the performance period of the contract.

Certain of our U.S. Government contracts span one or more base years and multiple option years. The U.S. Government generally has the right not to exercise option periods and may not exercise an option period for various reasons including, but not limited to, annual funding determinations. In addition, contracts between the U.S. Government and its prime contractors usually contain standard provisions for termination at the convenience of the U.S. Government or the prime contractor. As a U.S. Government contractor, we are subject to federal regulations under which our right to receive future awards of new federal contracts would be unilaterally suspended or barred if we were convicted of a crime or indicted based on allegations of a violation of specific federal statutes. In addition, some of our contracts with the U.S. Government require us to provide advance notice in connection with any contemplated sale or shut down of the relevant facility. In each of those situations, the U.S. Government has an exclusive right to negotiate a mutually acceptable purchase of the facility.

Technical Services

This segment’s principal operations include the management and operation of nuclear weapons production facilities, environmental management sites and the management of spent nuclear fuel and transuranic waste for the DOE. These activities are primarily accomplished through our participation in joint ventures with other contractors as further discussed under the caption "Joint Ventures" below.

The contracts for the management and operation of U.S. Government facilities are awarded through a complex and protracted procurement process. These contracts are generally structured as five-year contracts with five-year renewal options,

Table of Contents

which are exercisable by the customer, or include provisions whereby the contract durations can be extended as a result of the achievement of certain performance metrics. These are cost-reimbursement contracts with a U.S. Government credit line with some corporate-funded working capital required. However, many new contracts currently in the bidding process and recently awarded have a different structure. While these new contracts remain cost-reimbursement contracts, the contractor may be required to supply working capital and be reimbursed by the U.S. Government through regular invoicing. These contracts include a fee that is primarily based on performance, which is evaluated annually.

Nuclear Energy

Contracts in this segment are usually awarded through a competitive bid process. Factors that customers may consider include price, plant or equipment availability, technical capabilities of equipment and personnel, efficiency, safety record and reputation. The majority of these contracts are fixed-price contracts in which the specified scope of work is agreed to for a pre-determined price that is generally not subject to adjustment regardless of costs incurred by the contractor unless changes in scope are authorized by the customer. Fixed-price contracts entail more risk to us because they require us to predetermine both the quantities of work to be performed and the costs associated with executing the work.

Our arrangements with customers may require us to provide letters of credit, bid and performance bonds or guarantees to secure bids or performance under contracts, which may involve significant amounts for contract security.

Backlog

Backlog represents the dollar amount of revenue we expect to recognize in the future from contracts awarded and in progress. Not all of our expected revenue from a contract award is recorded in backlog for a variety of reasons, including that some projects are awarded and completed within the same fiscal quarter.

Backlog is not a measure defined by generally accepted accounting principles. It is possible that our methodology for determining backlog may not be comparable to methods used by other companies. We are subject to the budgetary and appropriations cycle of the U.S. Government as it relates to our Nuclear Operations and Technical Services segments. Backlog may not be indicative of future operating results, and projects in our backlog may be cancelled, modified or otherwise altered by customers.

We generally include expected revenue from contracts in our backlog when we receive written confirmation from our customers authorizing the performance of work and a commitment from the customer to payment for work performed. Accordingly, we exclude from backlog orders or arrangements that have been awarded but for which we have not been authorized to begin performance.

Our backlog at December 31, 2016 and 2015 was as follows:



	December 31, 2016				December 31, 2015
	(Dollars in millions)
Nuclear Operations	$	3,485	88	%	$	2,311	87	%
Technical Services	5		—	%	4		—	%
Nuclear Energy	493		12	%	335		13	%
Total Backlog	$	3,983	100	%	$	2,650	100	%

We do not include the value of our unconsolidated joint venture contracts in backlog. These unconsolidated joint ventures are primarily included in our Technical Services segment. See Note 4 to our consolidated financial statements included in this report for financial information on our equity method investments.

Table of Contents

Of the December 31, 2016 backlog, we expect to recognize revenues as follows:



	2017		2018		Thereafter		Total
	(In approximate millions)
Nuclear Operations	$	1,246	$	1,132	$	1,107	$	3,485
Technical Services	5		—		—		5
Nuclear Energy	197		106		190		493
Total Backlog	$	1,448	$	1,238	$	1,297	$	3,983

As of December 31, 2016, Nuclear Operations backlog with the U.S. Government was $3,474.8 million, of which $265.3 million had not yet been funded.

As of December 31, 2016, Technical Services backlog with the U.S. Government was $4.8 million, all of which was fully funded.

As of December 31, 2016, Nuclear Energy had no backlog with the U.S. Government.

Major new awards from the U.S. Government are typically received following Congressional approval of the budget for the government’s next fiscal year, which starts October 1, and may not be awarded to us before the end of the calendar year. Due to the fact that most contracts awarded by the U.S. Government are subject to these annual funding approvals, the total values of the underlying programs are significantly larger. In April 2016, we were awarded a component and fuel contract, along with a three-year downblending contract by the U.S. Government with a combined value in excess of $3.0 billion. Approximately $2.1 billion of these awards were added to backlog during the year ended December 31, 2016.

The value of unexercised options as of December 31, 2016 was approximately $0.9 billion, which are expected to be exercised periodically through 2018, subject to annual Congressional appropriations.

Competition

The competitive environments in which each segment operates are described below.

Nuclear Operations. We have specialized technical capabilities that have allowed us to be a valued supplier of nuclear components and fuel for the U.S. Government’s naval nuclear fleet since the 1950s. Because of the technical and regulatory standards required to meet U.S. Government contracting requirements for nuclear components and the barriers to entry present in this type of environment, competition in this segment is limited. The primary bases of limited competition for this segment are price, high capital investment, technical capabilities, high regulatory licensing costs and quality of products and services.

Technical Services. Through this segment, we are engaged in the management and operation of U.S. Government facilities and the delivery of environmental remediation services (decontamination and decommissioning) associated with U.S. Government-owned nuclear facilities. Many of our government contracts are bid as a joint venture with one or more companies, in which we have a majority or a minority position. The performance of the prime or lead contractor can impact our reputation and our future competitive position with respect to that particular project and customer. Our primary competitors in the delivery of goods and services to the U.S. Government and the operation of U.S. Government facilities include Bechtel National, Inc., AECOM, CH2M, Fluor Corporation, Lockheed Martin Corporation, Jacobs Engineering Group, Inc., Northrop Grumman Corporation, Honeywell International, Inc. and Leidos, Inc. The primary bases of competition for this segment are experience, past performance, availability of key personnel and technical capabilities.

Nuclear Energy. Our Nuclear Energy segment supplies commercial nuclear steam generators and components. BWXT has supplied the nuclear industry with more than 1,300 large, heavy components worldwide. This segment is the only commercial heavy nuclear component manufacturer in North America. Our Nuclear Energy segment fabricates pressure vessels, reactor components, steam generators, heat exchangers and other auxiliary equipment. This segment also provides specialized engineering and maintenance services, including services for plant outages. Through the acquisition of NEC, this segment is also a leading supplier of nuclear fuel, fuel handling systems, tooling delivery systems and replacement components for CANDU reactors. This segment competes with a number of companies specializing in nuclear capabilities including AREVA Inc., Cameco Corporation, Doosan Heavy Industries & Construction, Westinghouse Electric Corporation and SNC-Lavalin Group, Inc. The primary bases of competition for this segment are price, technical capabilities, quality, timeliness of performance, breadth of products and services and willingness to accept project risks.

Table of Contents

Joint Ventures

We share in the ownership of a variety of entities with third parties, primarily through corporations, limited liability companies and partnerships, which we refer to as "joint ventures." Through several joint venture arrangements, our Technical Services segment primarily manages and operates nuclear facilities and associated plant infrastructure, manufactures components and assembles/dismantles nuclear devices, constructs large capital facilities, provides safeguards and security for inventory and assets, supports and conducts research and development for advanced energy technology and manages environmental programs for the DOE, the NNSA and NASA. We generally account for our investments in joint ventures under the equity method of accounting. Certain of our Technical Services segment unconsolidated joint ventures are described below.

Foreign Operations

We have Canadian operations in our Nuclear Energy segment, which serve the North American and global electric utility, industrial power and global nuclear utility markets. The functional currency of these operations is not the U.S. dollar, and, as a result, we are subject to exchange rate fluctuations that impact our financial position, results of operations and cash flows. Revenue and operating income derived from Canadian operations, as well as the approximate percentages of our total segment revenues and total segment operating income, respectively, for each of the last three years were as follows (dollars in thousands):



	Revenues				Operating Income
	Amount		Percent		Amount		Percent
Year Ended December 31, 2016	$	160,504	10	%	$	47,302	15	%
Year Ended December 31, 2015	$	119,575	8	%	$	16,461	6	%
Year Ended December 31, 2014	$	110,986	8	%	$	86	—	%

For additional information on the geographic distribution of our revenues, see Note 17 to our consolidated financial statements included in this report.

Customers

We provide our products and services to a diverse customer base, including the U.S. Government, utilities and other power producers. Our largest customer during the years ended December 31, 2016, 2015 and 2014 was the U.S. Government; U.S. Government contracts represented approximately 87%, 88% and 88% of our total consolidated revenues, respectively. No individual non-U.S. Government customer accounted for more than 5% of our consolidated revenues in the years ended December 31, 2016, 2015 or 2014.

The U.S. Government is the primary customer of our Nuclear Operations and Technical Services segments. Revenues from U.S. Government contracts comprised 99% of revenues in our Nuclear Operations segment for the years ended December 31, 2016, 2015 and 2014. Revenues from U.S. Government contracts comprised 97%, 99% and 87% of revenues in our Technical Services segment for the years ended December 31, 2016, 2015 and 2014, respectively.

Raw Materials and Suppliers

Our operations use raw materials, such as carbon and alloy steels in various forms and components and accessories for assembly, which are available from numerous sources. We generally purchase these raw materials and components as needed for individual contracts. Our Nuclear Energy segment does not depend on a single source of supply for materials used in our products. We have limited supply options for certain raw materials used in our Nuclear Energy segment, however we believe the suppliers of these materials are reliable. Our Nuclear Operations segment relies on several single-source suppliers for materials used in its products. We believe these suppliers are reliable, and we and the U.S. Government expend significant effort to monitor and maintain the supplier base for our Nuclear Operations segment.

Although shortages of some raw materials have existed occasionally, no serious shortage exists at the present time.

Employees

At December 31, 2016, we employed approximately 5,900 persons worldwide. Approximately 1,200 of our employees were members of labor unions at December 31, 2016. Many of our operations are subject to union contracts, which we customarily renew periodically. We consider our relationships with our employees to be satisfactory.

Patents and Technology Licenses

We currently hold a large number of U.S. and foreign patents and have patent applications pending. We acquire patents and technology licenses and grant licenses to others when we consider it advantageous for us to do so. Although in the aggregate our patents and technology licenses are important to us, we do not regard any single patent or license or group of related patents or licenses as critical or essential to our business as a whole. In general, we depend on our technological capabilities and the application of know-how, rather than patents and technology licenses, in the conduct of our various businesses.

Research and Development Activities

Our research and development activities are related to the development and improvement of new and existing products and equipment, as well as conceptual and engineering evaluation for translation into practical applications. We charge the costs of research and development unrelated to specific contracts as incurred. Excluding customer-sponsored research and development, substantially all of these costs are related to our mPower program for the development of our BWXT mPower™ reactor and the associated power plant. Contractual arrangements for customer-sponsored research and development can vary on a case-by-case basis and include contracts, cooperative agreements and grants.

Research and development activities totaled $40.1 million, $38.2 million and $124.3 million in the years ended December 31, 2016, 2015 and 2014, respectively. These activities include amounts paid for by our customers of $33.7 million, $27.7 million and $41.7 million, in the years ended December 2016, 2015 and 2014, respectively. Funds provided under a Cooperative Agreement with the DOE under its Small Modular Reactor Licensing Technical Support Program (the "Funding Program") totaled $27.8 million in the year ended December 31, 2014. At this time, the latest extension under the Cooperative Agreement has expired and the DOE funding has been suspended.

During the year ended December 31, 2014, we recognized $5.8 million of non-cash in-kind research and development costs (included above) related to services contributed by our partner in GmP, our joint venture formed in 2011 to oversee the program to develop the small modular nuclear power plant based on BWXT mPower™ technology.

Hazard Risks and Insurance

Our operations present risks of injury to or death of people, loss of or damage to property and damage to the environment. We have created loss control systems to assist us in the identification and treatment of the hazard risks presented by our operations, and we endeavor to make sure these systems are effective.

As loss control measures will not always be successful, we seek to establish various means of funding losses and liability related to incidents or occurrences. We primarily seek to do this through contractual protections, including waivers of consequential damages, indemnities, caps on liability, liquidated damages provisions and access to the insurance of other parties. We also procure insurance, operate our own captive insurance company and/or establish funded or unfunded reserves. However, none of these methods will eliminate all risks.

Depending on competitive conditions, the nature of the work, industry custom and other factors, we may not be successful in obtaining adequate contractual protection from our customers and other parties against losses and liabilities arising out of or related to the performance of our work. The scope of the protection may be limited, may be subject to conditions and may not be supported by adequate insurance or other means of financing. In addition, we sometimes have difficulty enforcing our contractual rights with others following a material loss.

Similarly, insurance for certain potential losses or liabilities may not be available or may only be available at a cost or on terms we consider not to be economical. Insurers frequently react to market losses by ceasing to write or severely limiting coverage for certain exposures. Risks that we have frequently found difficult to cost-effectively insure against include, but are not limited to, property losses from wind, flood and earthquake events, nuclear hazards and war, pollution liability, liabilities related to occupational health exposures (including asbestos), liability related to our executives participating in the management of certain outside entities, professional liability/errors and omissions coverage, the failure, misuse or unavailability of our information technology systems, the failure of security measures designed to protect our information technology systems from security breaches and liability related to risk of loss of our work in progress. In cases where we place insurance, we are subject to the credit worthiness of the relevant insurer(s), the available limits of the coverage, our retention under the relevant policy, exclusions in the policy and gaps in coverage.

Table of Contents

Our operations in designing, engineering, manufacturing, constructing and servicing nuclear power equipment and components for our commercial nuclear utility customers subject us to various risks, including, without limitation, damage to our customers' property and third-party claims for personal injury, environmental liability, death and property damage. To protect against liability for damage to a customer's property, we endeavor to obtain waivers of liability and subrogation from the customer and its insurer. We also attempt to cap our overall liability in our contracts. To protect against liability from claims brought by third parties, we seek to be insured under the utility customer's nuclear liability policies and have the benefit of the indemnity and limitation of any applicable liability provision of the Price-Anderson Act. The Price-Anderson Act limits the public liability of U.S. manufacturers and operators of licensed nuclear facilities and other parties who may be liable in respect of, and indemnifies them against, all claims in excess of a certain amount. This amount is determined by the sum of commercially available liability insurance plus certain retrospective premium assessments payable by operators of commercial nuclear reactors. For those sites where we provide environmental remediation services, we seek the same protection from our customers as we do for our other nuclear activities. The Price-Anderson Act, as amended, includes a sunset provision and requires renewal each time that it expires. Contracts that were entered into during a period of time that Price-Anderson was in full force and effect continue to receive the benefit of the Price-Anderson Act's nuclear indemnity. The Price-Anderson Act is set to expire on December 31, 2025. We also provide nuclear fabrication and other services to the nuclear power industry in Canada. Canada's Nuclear Liability and Compensation Act generally conforms to international conventions and is conceptually similar to the Price-Anderson Act in the U.S. Accordingly, indemnification protections and the possibility of exclusions under Canada's Nuclear Liability and Compensation Act are similar to those under the Price-Anderson Act in the U.S.

We supply commercial nuclear equipment and services to certain customers in countries other than the U.S. and Canada that are party to international treaties and in countries that are not signatory to international treaties but have their own nuclear liability laws that in general, have regulations in place whereby nuclear operators are solely liable for nuclear damage claims, which would exclude nuclear suppliers from any such exposure. BWXT does retain some level of risk in the event of future changes to the legal landscape in these countries regarding international third-party nuclear liability.

In 2008, the U.S. ratified the Convention on Supplementary Compensation for Nuclear Damage ("CSC") with the International Atomic Energy Agency. The CSC is an international treaty developed to create a global legal framework for allocating responsibility and assuring prompt and equitable compensation in the unlikely event of certain nuclear incidents. The ratification by the U.S. authorizes the Secretary of Energy to issue regulations establishing a retrospective risk pooling program whereby, in the event that the U.S. must make a contribution to the CSC international fund, U.S. nuclear suppliers, including BWXT, would pay the full cost of this contribution by the U.S.

Although we do not own or operate any nuclear reactors, we have some coverage under commercially available nuclear liability and property insurance for our facilities that are currently licensed to possess special nuclear materials. Substantially all of our Nuclear Operations segment contracts involving nuclear materials are covered by and subject to the nuclear indemnity provisions of either the Price-Anderson Act or Public Law 85-804, which, among other things, authorizes the DOE to indemnify certain contractors when such acts would facilitate national defense. However, to the extent the value of the nuclear materials in our care, custody or control exceeds the commercially available limits of our insurance, we potentially have underinsured risk of loss for such nuclear material.

Our Technical Services segment participates in the management and operation of various U.S. Government facilities. This participation is customarily accomplished through the participation in joint ventures with other contractors for any given facility. These activities involve, among other things, handling nuclear devices and their components. Insurable liabilities arising from these sites are rarely protected by our or our partners' corporate insurance programs. Instead, we rely on government contractual agreements and insurance purchased specifically for a site. The U.S. Government has historically fulfilled its contractual agreement to reimburse its contractors for covered claims, and we expect it to continue this process during our participation in the administration of these facilities. However, in most of these situations in which the U.S. Government is contractually obligated to pay, the payment obligation is subject to the availability of authorized government funds. The reimbursement obligation of the U.S. Government is also conditional, and provisions of the relevant contract or applicable law may preclude reimbursement.

Our wholly owned captive insurance subsidiary provides workers' compensation, employer's liability, commercial general liability and automotive liability insurance to support our operations. We may also have business reasons in the future to have our insurance subsidiary accept other risks that we cannot or do not wish to transfer to outside insurance companies. These risks may be considerable in any given year or cumulatively. Our insurance subsidiary has not provided significant amounts of insurance to unrelated parties. Claims as a result of our operations could adversely impact the ability of our insurance subsidiary to respond to all claims presented.

Additionally, upon the February 22, 2006 effectiveness of the settlement relating to the Chapter 11 proceedings involving several of our subsidiaries, most of our subsidiaries contributed substantial insurance rights to the asbestos personal injury trust, including rights to (1) certain pre-1979 primary and excess insurance coverages and (2) certain of our 1979-1986 excess insurance coverage. These insurance rights provided coverage for, among other things, asbestos and other personal injury claims, subject to the terms and conditions of the policies. The contribution of these insurance rights was made in exchange for the agreement on the part of the representatives of the asbestos claimants, including the representative of future claimants, to the entry of a permanent injunction, pursuant to Section 524(g) of the U.S. Bankruptcy Code, to channel to the asbestos trust all asbestos-related general liability claims against our subsidiaries and former subsidiaries arising out of, resulting from or attributable to their operations, and the implementation of related releases and indemnification provisions protecting those subsidiaries and their affiliates from future liability for such claims. Although we are not aware of any significant, unresolved claims against our subsidiaries and former subsidiaries that are not subject to the channeling injunction and that relate to the periods during which such excess insurance coverage related, with the contribution of these insurance rights to the asbestos personal injury trust, it is possible that we could have underinsured or uninsured exposure for non-derivative asbestos claims or other personal injury or other claims that would have been insured under these coverages had the insurance rights not been contributed to the asbestos personal injury trust. In conjunction with the spin-off of our former Power Generation business, claims and liabilities associated with these asbestos personal injury, property damage and indirect property damage claims have been expressly assumed by BWE pursuant to the master separation agreement between us and BWE.

Governmental Regulations and Environmental Matters

General

Many aspects of our operations and properties are affected by political developments and are subject to both domestic and foreign governmental regulations, including those relating to:


•	possessing and processing special nuclear materials;


•	workplace health and safety;


•	constructing and equipping electric power facilities;


•	currency conversions and repatriation;


•	taxation of earnings; and


•	protecting the environment.

We are required by various governmental and quasi-governmental agencies to obtain certain permits, licenses and certificates with respect to our operations. The kinds of permits, licenses and certificates required in our operations depend upon a number of factors.

We cannot determine the extent to which new legislation, new regulations or changes in existing laws or regulations may affect our future operations.

Environmental

Our operations and properties are subject to a wide variety of increasingly complex and stringent foreign, federal, state and local environmental laws and regulations, including those governing discharges into the air and water, the handling and disposal of solid and hazardous wastes, the remediation of soil and groundwater contaminated by hazardous substances and the health and safety of employees. Sanctions for non-compliance may include revocation of permits, corrective action orders, administrative or civil penalties and criminal prosecution. Some environmental laws provide for strict, joint and several liability for remediation of spills and other releases of hazardous substances, as well as damage to natural resources. In addition, companies may be subject to claims alleging personal injury or property damage as a result of alleged exposure to hazardous substances. Such laws and regulations may also expose us to liability for the conduct of or conditions caused by others or for our acts that were in compliance with all applicable laws at the time such acts were performed.

These laws and regulations include the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended ("CERCLA"), the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act and similar laws that provide for responses to, and liability for, releases of hazardous substances into the environment. These laws and regulations also include similar foreign, state or local counterparts to these federal laws, which regulate air emissions, water discharges, hazardous substances and waste and require public disclosure related to the use of various hazardous

Table of Contents

substances. Our operations are also governed by laws and regulations relating to workplace safety and worker health, including the U.S. Occupational Safety and Health Act and regulations promulgated thereunder.

We are currently in the process of investigating and remediating some of our current and former operating sites. Although we have recorded reserves in connection with certain of these matters, due to the uncertainties associated with environmental remediation, there can be no assurance that the actual costs resulting from these remediation matters will not exceed the recorded reserves.

Our compliance with U.S. federal, state and local environmental control and protection regulations resulted in pre-tax charges of approximately $14.2 million, $14.1 million and $13.2 million in the years ended December 31, 2016, 2015 and 2014, respectively. In addition, compliance with existing environmental regulations necessitated capital expenditures of $1.3 million, $0.7 million and $0.3 million in the years ended December 31, 2016, 2015 and 2014, respectively. We expect to spend another $4.3 million on such capital expenditures over the next five years. We cannot predict all of the environmental requirements or circumstances that will exist in the future, but we anticipate that environmental control and protection standards will become increasingly stringent and costly. Based on our experience to date, we do not currently anticipate any material adverse effect on our business or consolidated financial condition as a result of future compliance with existing environmental laws and regulations. However, future events, such as changes in existing laws and regulations or their interpretation, more vigorous enforcement policies of regulatory agencies or stricter or different interpretations of existing laws and regulations, may require additional expenditures by us, which may be material. Accordingly, we can provide no assurance that we will not incur significant environmental compliance costs in the future.

We have been identified as a potentially responsible party at various cleanup sites under CERCLA. CERCLA and other environmental laws can impose liability for the entire cost of cleanup on any of the potentially responsible parties, regardless of fault or the lawfulness of the original conduct. Generally, however, where there are multiple responsible parties, a final allocation of costs is made based on the amount and type of wastes disposed of by each party and the number of financially viable parties, although this may not be the case with respect to any particular site. We have not been determined to be a major contributor of wastes to any of these sites. On the basis of our relative contribution of waste to each site, we expect our share of the ultimate liability for the various sites will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows in any given year.

Environmental remediation projects have been and continue to be undertaken at certain of our current and former plant sites. In 2002, Congress directed the U.S. Army Corps of Engineers ("Army Corps") to clean up radioactive waste at the Shallow Land Disposal Area located in Parks Township, Armstrong County, Pennsylvania (the "SLDA"), consistent with the Memorandum of Understanding between the NRC and the Army Corps for Coordination on Cleanup and Decommissioning of the Formerly Utilized Sites Remedial Action Program Sites with NRC-Licensed Facilities, dated July 5, 2001 (the "MOU"). From 1961 to 1970, the SLDA was operated by the Nuclear Materials and Equipment Corporation ("NUMEC") pursuant to Atomic Energy Commission ("AEC") License SNM-145. The AEC was the predecessor to the NRC. The SLDA was used for the disposal of waste from NUMEC’s nuclear fuels fabrication facility in Apollo, Pennsylvania. Both radioactive and non-radioactive waste was disposed in a series of trenches at the SLDA. NUMEC, a former subsidiary of Atlantic Richfield Company ("ARCO") was acquired by BWXT in November 1971. After the Army Corps’ contractor commenced cleanup operations, the Army Corps ceased excavation activities because the contractor deviated from accepted field procedures, and the excavated material was found to be complex and beyond the Army Corps’ characterization and management procedures. The MOU was modified in late 2014 to add the DOE and the NNSA as parties to deal with "special nuclear materials." In December 2014, the Army Corps issued a Proposed Record of Decision Amendment, which reflects a revised cost estimate of $350 million, in addition to the $62 million expended through September 2014, to implement the selected remedy. The Army Corps expects to award a new remediation contract in 2017, and cleanup operations are expected to re-commence in 2019. The federal legislation directing the Army Corps to clean up the SLDA also directs the Army Corps to seek to recover response costs from appropriate responsible parties in accordance with CERCLA. In connection with BWXT’s acquisition of NUMEC from ARCO in November 1971, ARCO assumed and agreed to indemnify and hold harmless BWXT with respect to claims and liabilities arising as a result of transactions or operations of NUMEC prior to the acquisition date. Although this ARCO indemnity would cover claims by the Army Corps to seek recovery from BWXT, no assurance can be given that such indemnity will be available or sufficient in the event liability claims are asserted for SLDA cleanup costs against BWXT.

Table of Contents

The NRC’s decommissioning regulations require our Nuclear Operations segment to provide financial assurance that it will be able to pay the expected cost of decommissioning each of its licensed facilities at the end of its service life. We provided financial assurance aggregating $56.2 million and $52.3 million during the years ended December 31, 2016 and 2015 with existing letters of credit for the ultimate decommissioning of these licensed facilities. These two facilities have provisions in their government contracts pursuant to which substantially all of our decommissioning costs and financial assurance obligations are covered by the DOE, including the costs to complete the decommissioning projects underway at the Erwin, Tennessee facility. These letters of credit are to cover decommissioning required pursuant to work not subject to this DOE obligation.

In Canada, the CNSC’s decommissioning regulations require our Nuclear Energy segment to provide financial assurance that it will be able to pay the expected cost of decommissioning each of its CNSC licensed facilities at the end of its service life. We provided financial assurance totaling $39.5 million during the year ended December 31, 2016 with a letter of credit for the ultimate decommissioning of these licensed facilities.

At December 31, 2016 and 2015, we had total environmental accruals, including provisions for the facilities discussed above, of $86.3 million and $63.4 million, respectively. Of our total environmental accruals at December 31, 2016 and 2015, $4.6 million and $3.2 million, respectively, were included in current liabilities. Inherent in the estimates of those accruals and recoveries are our expectations regarding the levels of contamination, decommissioning costs and recoverability from other parties, which may vary significantly as decommissioning activities progress. Accordingly, changes in estimates could result in material adjustments to our operating results, and the ultimate loss may differ materially from the amounts we have provided for in our consolidated financial statements.

Cautionary Statement Concerning Forward-Looking Statements

We are including the following discussion to inform our existing and potential security holders generally of some of the risks and uncertainties that can affect our company and to take advantage of the "safe harbor" protection for forward-looking statements that applicable federal securities law affords.

From time to time, our management or persons acting on our behalf make forward-looking statements to inform existing and potential security holders about our Company. Statements and assumptions regarding expectations and projections of specific projects, our future backlog, revenues, income and capital spending, acquisitions or divestitures, return of capital activities or margin improvement initiatives are examples of forward-looking statements. Forward-looking statements are generally accompanied by words such as "estimate," "project," "predict," "believe," "expect," "anticipate," "plan," "seek," "goal," "could," "intend," "may," "should" or other words that convey the uncertainty of future events or outcomes. In addition, sometimes we will specifically describe a statement as being a forward-looking statement and refer to this cautionary statement.

In addition, various statements in this annual report on Form 10-K, including those that express a belief, expectation or intention, as well as those that are not statements of historical fact, are forward-looking statements. Those forward-looking statements appear in Item 1 – "Business" and Item 3 – "Legal Proceedings" in Part I of this report and in Item 7 – "Management’s Discussion and Analysis of Financial Condition and Results of Operations" and in the notes to our consolidated financial statements in Item 8 of Part II of this report and elsewhere in this report.

We have based our forward-looking statements on information currently available to us and our current expectations, estimates and projections about our industries and our Company. We caution that these statements are not guarantees of future performance and you should not rely unduly on them, as they involve risks, uncertainties and assumptions that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. While our management considers these statements and assumptions to be reasonable, they are inherently subject to numerous factors, including potentially the risk factors described in the section labeled Item 1A, "Risk Factors" of this report, most of which are difficult to predict and many of which are beyond our control. Accordingly, our actual results may differ materially from the future performance that we have expressed or forecast in our forward-looking statements.

We have discussed many of these factors in more detail elsewhere in this report. These factors are not necessarily all the factors that could affect us. Unpredictable or unanticipated factors we have not discussed in this report could also have material adverse effects on actual results of matters that are the subject of our forward-looking statements. We do not intend to update or review any forward-looking statement or our description of important factors, whether as a result of new information, future events or otherwise, except as required by applicable laws. We advise our security holders that they should (1) be aware that factors not referred to above could affect the accuracy of our forward-looking statements and (2) use caution and common sense when considering our forward-looking statements.

Item 1A.	RISK FACTORS

Risk Factors Related to Our Business

We rely on U.S. Government contracts for a substantial percentage of our revenue, and some of those contracts are subject to continued appropriations by Congress and may be terminated or delayed if future funding is not made available. In addition, the U.S. Government may not renew or may seek to modify or terminate our existing contracts.

For the year ended December 31, 2016, we relied on U.S. Government contracts for approximately 87% of our total consolidated revenues. Government contracts are subject to various uncertainties, restrictions and regulations, including oversight audits, which could result in withholding or delaying payments to us, and termination or modification at the U.S. Government's convenience. In addition, some of our large, multi-year contracts with the U.S. Government are subject to annual funding determinations and the continuing availability of Congressional appropriations. Although multi-year operations may be planned in connection with major procurements, Congress generally appropriates funds on a fiscal-year basis even though a program may continue for several years. Consequently, programs often are only partially funded initially and additional funds are committed only as Congress makes further appropriations. When the U.S. Government does not complete its budget process before the end of its fiscal year on September 30, government operations typically are funded through a continuing resolution that authorizes agencies of the U.S. Government to continue to operate, but does not authorize new spending initiatives. When the U.S. Government operates under a continuing resolution, delays can occur in the procurement of products and services. As a result, we are subject to ongoing uncertainties associated with U.S. Government budget restraints and other factors affecting government funding. The reduction or termination of funding, or changes in the timing of funding, for a U.S. Government program in which we provide products or services would result in a reduction or loss of anticipated future revenues attributable to that program and could have a negative impact on our results of operations.

In addition, our Nuclear Operations and Technical Services segments depend on U.S. Government funding, particularly funding levels at the DOE. Significant changes in the level of funding (for example, the annual budget of the DOE) or specifically mandated levels for individual programs that are important to our business could have an unfavorable impact on us. Any reduction in the level of U.S. Government funding, particularly at the DOE, may result in, among other things, a reduction in the number and scope of projects put out for bid by the U.S. Government or the curtailment of existing U.S. Government programs, either of which may result in a reduction in the number of contract award opportunities available to us, a reduction of activities at DOE sites and an increase in costs, including the costs of obtaining contract awards.

The U.S. Government typically can terminate or modify any of its contracts with us either for its convenience or if we default by failing to perform under the terms of the applicable contract. A termination arising out of our default could expose us to liability and have an adverse effect on our ability to compete for future contracts and orders. If any of our contracts reflected in backlog are terminated by the U.S. Government, our backlog would be reduced by the expected value of the remaining work under such contracts. In addition, on those contracts for which we are teamed with others and are not the prime contractor, the U.S. Government could terminate a prime contract under which we are a subcontractor, irrespective of the quality of our products and services as a subcontractor. Furthermore, certain of our U.S. Government contracts span one or more base years and multiple option years. The U.S. Government generally has the right not to exercise option periods and may not exercise an option period for various reasons.

We also have several significant contracts with the U.S. Government that are subject to periodic renewal and rebidding through a competitive process. If the U.S. Government fails to renew these contracts or modifies key terms, our results of operations and cash flows would be adversely affected.

Table of Contents

As a result of these and other factors, the termination of one or more of our significant government contracts, our suspension from government contract work, the failure of the U.S. Government to renew our existing contracts or the disallowance of the payment of our contract costs could have a material adverse effect on our financial condition, results of operations and cash flows.

Federal budget sequestration and other delays or reductions in government spending could adversely impact government spending for the products and services we provide.

In August 2011, Congress enacted the Budget Control Act, which committed the U.S. Government to significantly reducing the federal deficit over ten years. The Budget Control Act established reductions in discretionary spending through 2021. If these spending reductions were not met, it called for substantial automatic spending cuts, or sequestration, split between defense and non-defense programs scheduled to start in March 2013 and continue over a nine-year period.

Federal government spending reductions, including through sequestration, could adversely impact U.S. Government programs for which we provide products or services. Additionally, while we believe many of our programs are well aligned with national defense and other strategic priorities, government spending on these programs can be subject to negative publicity, political factors and public scrutiny. The outcome of efforts underway regarding sequestration is uncertain and it is possible that spending cuts may be applied to U.S. Government programs across the board, regardless of how programs align with those priorities. There are many variables in how budget reductions could be implemented that will determine its specific impact; however, reductions in federal government spending and sequestration, as currently provided for under the Budget Control Act, could adversely impact programs in which we provide products or services. In addition, these cuts could adversely affect the viability of the suppliers and subcontractors under our programs. We may also be required to maintain operations of our joint ventures if the government can no longer meet its debt obligations.

The Bipartisan Budget Act of 2015 was approved in November 2015. This budget agreement provides sequestration relief and increased both defense and non-defense budgets by approximately $25 billion each in government fiscal year 2016 and $15 billion each in government fiscal year 2017 over the previous budget agreement approved in 2013, and extends the duration of the Budget Control Act through government fiscal year 2025. While this budget agreement provides some near-term relief, sequestration, reduction in government spending in lieu of sequestration or fiscal issues raised by negotiations over the federal debt ceiling remain a long-term concern.

Demand for our products and services is vulnerable to economic downturns, the competitiveness of alternative energy sources and industry conditions.

Demand for our products and services has been, and we expect that demand will continue to be, subject to significant fluctuations due to a variety of factors beyond our control, including economic and industry conditions. These factors include, but are not limited to inflation, geopolitical issues, the availability and cost of credit, the demand for and competitiveness of nuclear power with other energy sources, the cyclical nature of the power generation industry, low business and consumer confidence, high unemployment and energy conservation measures and decisions of utilities that utilize nuclear power.

Unfavorable economic conditions may lead customers to delay, curtail or cancel proposed or existing projects, which may decrease the overall demand for our products and services and adversely affect our results of operations.

Our customers may also find it more difficult to raise capital in the future due to limitations on the availability of credit, increases in interest rates and other factors affecting the federal, municipal and corporate credit markets. Additionally, our customers may demand more favorable pricing terms and find it increasingly difficult to timely pay invoices for our products and services, which would impact our future cash flows and liquidity. Inflation or significant changes in interest rates could reduce the demand for our products and services. Any inability to timely collect our invoices may lead to an increase in our accounts receivables and potentially to increased write-offs of uncollectible invoices. If the economy weakens, or customer spending declines, then our backlog, revenues, net income and overall financial condition could deteriorate.

Our future business prospects in Canada are dependent upon the continued operation of Canadian nuclear plants and refurbishment of the majority of the plants in Ontario in order to extend their life. Unfavorable economic conditions, competition from other forms of power generation, changes in government policy or operational or project execution issues may lead nuclear plant operators in Canada to cease operations or delay, curtail or cancel proposed or existing life-extension projects, which may decrease the overall demand for our products and services in Canada and adversely affect our results of operations.

Table of Contents

Our backlog is subject to unexpected adjustments and cancellations and may not be a reliable indicator of future revenues or earnings.

There can be no assurance that the revenues projected in our backlog will be realized or, if realized, will result in profits. Because of project cancellations or changes in project scope and schedule, we cannot predict with certainty when or if backlog will be performed. In addition, even where a project proceeds as scheduled, it is possible that contracted parties may default and fail to pay amounts owed to us or poor project performance could increase the cost associated with a project. Delays, suspensions, cancellations, payment defaults, scope changes and poor project execution could materially reduce or eliminate the revenues and profits that we actually realize from projects in backlog.

Reductions in our backlog due to cancellation or modification by a customer or for other reasons may adversely affect, potentially to a material extent, the revenues and earnings we actually receive from contracts included in our backlog. Many of the contracts in our backlog provide for cancellation fees in the event customers cancel projects. These cancellation fees usually provide for reimbursement of our out-of-pocket costs, revenues for work performed prior to cancellation and a varying percentage of the profits we would have realized had the contract been completed. However, we typically have no contractual right upon cancellation to the total revenues reflected in our backlog. Projects may remain in our backlog for extended periods of time. If we experience significant project terminations, suspensions or scope adjustments to contracts reflected in our backlog, our financial condition, results of operations and cash flows may be adversely impacted.

We are subject to risks associated with contractual pricing in our industries, including the risk that, if our actual costs exceed the costs we estimate on our fixed-price contracts, our profitability will decline and we may suffer losses.

We are engaged in highly competitive industries and we have priced a number of our projects on a fixed-price basis. Our actual costs could exceed our projections. We attempt to cover the increased costs of anticipated changes in labor, material and service costs of long-term contracts, either through estimates of cost increases, which are reflected in the original contract price, or through price escalation clauses. Despite these attempts, the cost and gross profit we realize on a fixed-price contract could vary materially from the estimated amounts because of supplier, contractor and subcontractor performance, changes in job conditions, variations in labor and equipment productivity and increases in the cost of labor and raw materials, particularly steel, over the term of the contract. These variations and the risks generally inherent in our industries may result in actual revenues or costs being different from those we originally estimated and may result in reduced profitability or losses on projects. Some of these risks include:


•	difficulties encountered on our large-scale projects related to the procurement of materials or due to schedule disruptions, equipment performance failures, unforeseen site conditions, rejection clauses in customer contracts or other factors that may result in additional costs to us, reductions in revenue, claims or disputes;


•	our inability to obtain compensation for additional work we perform or expenses we incur as a result of our customers providing deficient design, engineering information, equipment or materials;


•	requirements to pay liquidated damages upon our failure to meet schedule or performance requirements of our contracts; and


•	difficulties in engaging third-party subcontractors, equipment manufacturers or materials suppliers or failures by third-party subcontractors, equipment manufacturers or materials suppliers to perform could result in project delays and cause us to incur additional costs.

If we fail to comply with government procurement laws and regulations, we could lose business and be liable for various penalties or sanctions.

We must comply with laws and regulations relating to the formation, administration, and performance of U.S. Government contracts. These laws and regulations include the Federal Acquisition Regulations, Defense Federal Acquisition Regulations, the Truth in Negotiations Act, Cost Accounting Standards, and laws, regulations, and orders restricting the use and dissemination of classified information under the U.S. export control laws and the export of certain products and technical information. Certain government contracts provide audit rights by government agencies, including with respect to performance, costs, internal controls and compliance with applicable laws and regulations. In complying with these laws and regulations, we may incur significant costs, and non-compliance may result in the imposition of fines and penalties, including contractual damages. If we fail to comply with these laws and regulations or if a government audit, review, or investigation uncovers improper or illegal activities, we may be subject to civil penalties, criminal penalties, or administrative sanctions, including suspension or debarment from contracting with the U.S. Government. Our reputation could suffer harm if allegations of impropriety were made or found against us, which could adversely affect our operating performance and may result in additional expenses and possible loss of revenue.

Changes in our effective tax rate and tax positions may vary.

We are subject to income taxes primarily in the U.S. and Canada. A change in tax laws, treaties or regulations, or their interpretation, in any jurisdiction in which we operate could significantly impact our provision for income taxes, which could have a material impact on our earnings, cash flows from operations and value of our deferred tax assets or liabilities. Recent proposals to lower the U.S. corporate income tax rate would require us to reduce the value in our net deferred tax assets upon enactment of new tax legislation, with a corresponding one-time non-cash increase in income tax expense. However, our income tax expense and cash tax payments would be materially lower in subsequent years.

In addition, significant judgment is required in determining our provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain, and we are regularly subject to audit by tax authorities. Although we believe that our tax estimates and tax positions are reasonable, they could be materially affected by many factors including the final outcome of tax audits and related litigation, the introduction of new tax accounting standards, legislation, regulations and related interpretations, the realizability of deferred tax assets and changes in uncertain tax positions. A significant increase in our tax rate could have a material adverse effect on our profitability and liquidity.

Our business could be negatively impacted by security threats, including physical and cybersecurity threats, and other disruptions.

We face various security threats, including cyber threats, threats to the physical security of our facilities and infrastructure (including those that we manage and operate for our customers), and threats from terrorist acts, as well as the potential for business disruptions associated with these threats. Although we utilize a combination of tailored and industry standard security measures and technology to monitor and mitigate these threats, we cannot guarantee that these measures and technology will be sufficient to prevent security threats from materializing.

We have been, and will likely continue to be, subject to cyber-based attacks and other attempts to threaten our information technology systems, including attempts to gain unauthorized access to our proprietary or classified information and attacks from computer hackers, viruses, malicious code and other security problems. As a U.S. Government contractor, we may be prone to a greater number of those threats than companies in other industries. From time to time, we experience system interruptions and delays; however, prior cyber-based attacks directed at us have not had a material adverse impact on our results of operations. Due to the evolving nature of these security threats, however, the impact of any future incident cannot be predicted.

The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. Occurrence of any of these events could adversely affect our internal operations, the services we provide to customers, the value of our investment in research and development efforts and other intellectual property, our future financial results, our reputation or our stock price.

In addition, from time to time we may replace and/or upgrade current financial, human resources and other information technology systems. These activities subject us to inherent costs and risks associated with replacing and updating these systems, including potential disruption of our internal control structure, substantial capital expenditures, demands on management time and other risks of delays or difficulties in transitioning to new systems or of integrating new systems into our current systems. Our systems' implementations and upgrades may not result in productivity improvements at the levels anticipated, or at all. In addition, the implementation of new technology systems may cause disruptions in our business operations. Such disruption and any other information technology system disruptions, and our ability to mitigate those disruptions, if not anticipated and appropriately mitigated, could have a material adverse effect on us.

We rely on intellectual property law and confidentiality agreements to protect our intellectual property. We also rely on intellectual property we license from third parties. Our failure to protect our intellectual property rights, or our inability to obtain or renew licenses to use intellectual property of third parties, could adversely affect our business.

Our success depends, in part, on our ability to protect our proprietary information and other intellectual property. Our intellectual property could be stolen, challenged, invalidated, circumvented or rendered unenforceable. In addition, effective intellectual property protection may be limited or unavailable in some foreign countries where we operate.

Our failure to protect our intellectual property rights may result in the loss of valuable technologies or adversely affect our competitive business position. We rely significantly on proprietary technology, information, processes and know-how that are not subject to patent or copyright protection. We seek to protect this information through trade secret or confidentiality

Table of Contents

agreements with our employees, consultants, subcontractors or other parties, as well as through other security measures. These agreements and security measures may be inadequate to deter or prevent misappropriation of our confidential information. In the event of an infringement of our intellectual property rights, a breach of a confidentiality agreement or divulgence of proprietary information, we may not have adequate legal remedies to protect our intellectual property. Litigation to determine the scope of intellectual property rights, even if ultimately successful, could be costly and could divert management's attention away from other aspects of our business. In addition, our trade secrets may otherwise become known or be independently developed by competitors.

In some instances, we have augmented our technology base by licensing the proprietary intellectual property of third parties. In the future, we may not be able to obtain necessary licenses on commercially reasonable terms, which could have a material adverse effect on our operations.

Our use of the percentage-of-completion method of accounting could result in volatility in our results of operations.

We generally recognize revenues and profits under our long-term contracts on a percentage-of-completion basis. Accordingly, we review contract price and cost estimates regularly as the work progresses and reflect adjustments proportionate to the percentage of completion in income in the period when we revise those estimates. To the extent these adjustments result in a reduction or an elimination of previously reported profits with respect to a project, we would recognize a charge against current earnings, which could be material. Our current estimates of our contract costs and the profitability of our long-term projects, although reasonably reliable when made, could change as a result of the uncertainties associated with these types of contracts, and if adjustments to overall contract costs are significant, the reductions or reversals of previously recorded revenue and profits could be material in future periods.

We are involved in a number of legal proceedings. We cannot predict the outcome of litigation and other contingencies with certainty.

Our business may be adversely affected by the outcome of legal proceeding, disputes and other contingencies that cannot be predicted with certainty. As required by GAAP, we estimate loss contingencies and establish reserves based on our assessment of contingencies where liability is deemed probable and reasonably estimable in light of the facts and circumstances known to us at a particular point in time. Subsequent developments in legal proceedings may affect our assessment and estimates of the loss contingency recorded as a liability or as a reserve against assets in our financial statements. For a description of current legal proceedings, see Item 3 – Legal Proceedings and "Note 11 – Commitments and Contingencies" of our consolidated financial statements.

Maintaining adequate bonding and letter of credit capacity is necessary for us to successfully bid on and win various contracts.

In line with industry practice, we are often required to post standby letters of credit and surety bonds to support contractual obligations to customers as well as other obligations. These letters of credit and bonds generally indemnify customers should we fail to perform our obligations under the applicable contracts. If a letter of credit or bond is required for a particular project and we are unable to obtain it due to insufficient liquidity or other reasons, we will not be able to pursue that project. We utilize bonding facilities, but, as is typically the case, the issuance of bonds under each of those facilities is at the surety's sole discretion. In addition, we have capacity limits under our credit facility for letters of credit. Moreover, due to events that affect the insurance and bonding and credit markets generally, bonding and letters of credit may be more difficult to obtain in the future or may only be available at significant additional cost. There can be no assurance that letters of credit or bonds will continue to be available to us on reasonable terms. Our inability to obtain adequate letters of credit and bonding and, as a result, to bid on new work could have a material adverse effect on our business, financial condition and results of operations. As of December 31, 2016, we had $154.9 million in letters of credit and bank guarantees and $19.7 million in surety bonds outstanding.

Our credit facility could restrict our operations.

The terms of our credit agreement impose various restrictions and covenants on us that could have adverse consequences, including:


•	limiting our ability to react to changing economic, regulatory and industry conditions;


•	limiting our ability to compete and our flexibility in planning for, or reacting to, changes in our business and the industry;

Table of Contents


•	limiting our ability to invest in joint ventures or acquire other companies;


•	limiting our ability to pay dividends to our stockholders; and


•	limiting our ability to borrow additional funds.

Our failure to comply with these restrictions and covenants could adversely affect our liquidity and operations.

Our business strategy includes acquisitions to support our growth. Acquisitions of other businesses can create certain risks and uncertainties.

We intend to pursue growth through the acquisition of businesses or assets that we believe will enable us to strengthen our existing businesses and expand into adjacent industries. We may be unable to execute this growth strategy if we cannot identify suitable businesses or assets, reach agreement on potential strategic acquisitions on acceptable terms or for other reasons.

In December 2016, we completed our acquisition of NEC. Business acquisitions such as NEC involve certain risks, including:


•	difficulties relating to the assimilation of personnel, services and systems of an acquired business and the assimilation of marketing and other operational capabilities;


•	challenges resulting from unanticipated changes in customer relationships after the acquisition;


•	additional financial and accounting challenges and complexities in areas such as tax planning, treasury management, financial reporting and internal controls;


•	assumption of liabilities of an acquired business, including liabilities that were unknown at the time the acquisition transaction was negotiated;


•	diversion of management's attention from day-to-day operations;


•	failure to realize anticipated benefits, such as cost savings and revenue enhancements;


•	potentially substantial transaction costs associated with business combinations; and


•	potential impairment of goodwill or other intangible assets resulting from the overpayment for an acquisition.

Acquisitions may be funded by the issuance of additional equity or debt financing, which may not be available on attractive terms. Our ability to secure such financing will depend in part on prevailing capital market conditions, as well as conditions in our business and operating results. Moreover, to the extent an acquisition transaction financed by non-equity consideration results in goodwill, it will reduce our tangible net worth, which might have an adverse effect on potential credit and bonding capacity.

Additionally, an acquisition may bring us into businesses we have not previously conducted and expose us to additional business risks that are different than those we have historically experienced.

Our business strategy also includes development and commercialization of new technologies to support our growth, which requires significant investment and involves various risks and uncertainties. These new technologies may not achieve desired commercial or financial results.

Our future growth will depend on our ability to continue to innovate by developing and commercializing new product and service offerings. Investments in new technologies involve varying degrees of uncertainties and risk. Commercial success depends on many factors, including the levels of innovation, the development costs and the availability of capital resources to fund those costs, the levels of competition from others developing similar or other competing technologies, our ability to obtain or maintain government permits or certifications, the effectiveness of production, distribution and marketing efforts, and the costs to customers to deploy and provide support for the new technologies. We may not achieve significant revenue from new product and service investments for a number of years, if at all. Additionally, there can be no assurance that the current technologies that our businesses rely upon will remain competitive, or that competing technologies will not disrupt our business. Moreover, new products and services may not be profitable, and, even if they are profitable, our operating margins from new products and services may not be as high as the margins we have experienced historically. Lastly, new technologies may not be patentable and, as a result, we may face increased competition.

Among our opportunities involving new technologies, we are developing the BWXT mPower™ reactor. The costs to develop and commercialize this technology require a substantial amount of investment over a period of years and commercialization of this technology also requires certification from the NRC. There can be no assurance that we will be successful in addressing all of the technological challenges to developing and commercializing this technology or in obtaining the required NRC certification. The potential also exists for other competitors to emerge with competing technologies, in some cases with funding readily available, and we can provide no assurance that those competitors will not develop and commercialize similar or superior technologies sooner than we can or at a significant cost or price advantage.

In April 2013, BWXT mPower, Inc., a wholly owned subsidiary of BWXT, entered into a Cooperative Agreement with the DOE establishing a cost sharing program for the mPower™ reactor. Funding under this program was suspended in 2014, and we announced plans to restructure the mPower program to reduce spending and focus on technology development that same year.

On March 2, 2016, BWXT entered into a framework agreement with Bechtel, BWXT Modular Reactors, LLC and BDC NexGen Power, LLC for the potential restructuring and restart of the mPower program (the "Framework Agreement"). The Framework Agreement provides that during a twelve (12) month fundraising period beginning on the effective date of the Framework Agreement, Bechtel will attempt to secure funding from third parties (including the DOE) to complete development of the mPower Plant design sufficient to achieve design certification by the NRC. During this fundraising period, BWXT continues to advance the mPower design through in-kind engineering services within our previously announced planned mPower project spending of no more than $10.0 million per year.

In the event that Bechtel determines in its sole discretion that the mPower program should not be restarted, whether due to (1) adequate third-party funding not being secured, (2) the parties being unable to finalize the new GmP limited liability company agreement and other ancillary related agreements, or (3) otherwise, the mPower program would be terminated, GmP would be wound up and Bechtel would be entitled to payment of a settlement amount of $30.0 million (the "Settlement Amount"). Our sole liability and Bechtel's sole remedy arising out of the Framework Agreement will be our obligation to pay, and Bechtel's right to receive, respectively, the Settlement Amount. Any and all other previously existing claims, demands or actions between Bechtel and us arising out of the GmP LLC Agreement and ancillary related agreements, whether known or unknown (including Bechtel's previously asserted breach claim for $120.0 million), were released in connection with entering into the Framework Agreement.

Our operations are subject to operating risks, which could expose us to potentially significant professional liability, product liability, warranty and other claims. Our insurance coverage may be inadequate to cover all of our significant risks or our insurers may deny coverage of material losses we incur, which could adversely affect our profitability and overall financial condition.

We operate large manufacturing facilities and perform services in large commercial power plants where accidents or system failures can have significant consequences. Risks inherent in our operations include:


•	accidents resulting in injury or the loss of life or property;


•	environmental or toxic tort claims, including delayed manifestation claims for personal injury or loss of life;


•	pollution or other environmental mishaps;


•	adverse weather conditions;


•	mechanical or design failures;


•	property losses;


•	business interruption due to political action in foreign countries or other reasons; and


•	labor stoppages.

Any accident or failure at a site where we have provided products or services could result in significant professional liability, product liability, warranty and other claims against us, regardless of whether our products or services caused the incident. We have been, and in the future we may be, named as defendants in lawsuits asserting large claims as a result of litigation arising from events such as those listed above.

We endeavor to identify and obtain in established markets insurance agreements to cover significant risks and liabilities. Insurance against some of the risks inherent in our operations is either unavailable or available only at rates or on terms that we

Table of Contents

consider uneconomical. Also, catastrophic events customarily result in decreased coverage limits, more limited coverage, additional exclusions in coverage, increased premium costs and increased deductibles and self-insured retentions. Risks that we have frequently found difficult to cost-effectively insure against include, but are not limited to, business interruption, property losses from wind, flood and earthquake events, nuclear hazards and war, pollution liability, liabilities related to occupational health exposures (including asbestos), professional liability/errors and omissions coverage, the failure, misuse or unavailability of our information systems, the failure of security measures designed to protect our information systems from security breaches, and liability related to risk of loss of our work in progress and customer-owned materials in our care, custody and control. Depending on competitive conditions and other factors, we endeavor to obtain contractual protection against certain uninsured risks from our customers. When obtained, such contractual indemnification protection may not be as broad as we desire or may not be supported by adequate insurance maintained by the customer. Such insurance or contractual indemnity protection may not be sufficient or effective under all circumstances or against all hazards to which we may be subject. A successful claim for which we are not insured or for which we are underinsured could have a material adverse effect on us. Additionally, disputes with insurance carriers over coverage may affect the timing of cash flows and, if litigation with the carrier becomes necessary, an outcome unfavorable to us may have a material adverse effect on our results of operations.

We are also involved in management and operating activities for the U.S. Government. These activities involve, among other things, handling nuclear devices and their components for the U.S. Government. Most insurable liabilities arising from these sites are not protected in our corporate insurance program. Instead, we rely on government contractual agreements, some insurance purchased specifically for the sites and certain specialized self-insurance programs funded by the U.S. Government. The U.S. Government has historically fulfilled its contractual agreement to reimburse for insurable claims, and we expect it to continue this process. However, it should be noted that, in most situations, the U.S. Government is contractually obligated to pay subject to the availability of authorized government funds. The reimbursement obligation of the U.S. Government is also conditional, and provisions of the relevant contract or applicable law may preclude reimbursement.

We have a captive insurance company subsidiary that provides us with various insurance coverages. Claims, as a result of our operations, could adversely impact the ability of our captive insurance company subsidiary to respond to all claims presented.

Additionally, upon the February 22, 2006 effectiveness of the settlement relating to the Chapter 11 proceedings involving several of our former subsidiaries, most of our subsidiaries contributed substantial insurance rights providing coverage for, among other things, asbestos and other personal injury claims, to an asbestos personal injury trust. With the contribution of these insurance rights to the asbestos personal injury trust, we may have underinsured or uninsured exposure for non-derivative asbestos claims or other personal injury or other claims that would have been insured under these coverages had the insurance rights not been contributed to the asbestos personal injury trust. However, in conjunction with the spin-off of our former Power Generation business, claims and liabilities associated with the asbestos personal injury, property damage and indirect property damage claims mentioned above have been expressly assumed by BWE pursuant to the master separation agreement between us and BWE.

Our nuclear operations subject us to various environmental, regulatory, financial and other risks.

Our operations in designing, engineering, manufacturing, supplying, constructing and maintaining nuclear fuel and nuclear power equipment and components subject us to various risks, including:


•	potential liabilities relating to harmful effects on the environment and human health resulting from nuclear operations and the storage, handling and disposal of radioactive materials;


•	unplanned expenditures relating to maintenance, operation, security, defects, upgrades and repairs required by the NRC and other government agencies;


•	limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with nuclear operations; and


•	potential liabilities arising out of a nuclear, radiological or criticality incident, whether or not it is within our control.

Our nuclear operations are subject to various safety-related requirements imposed by the U.S. Government, the DOE and the NRC. In the event of non-compliance, these agencies might increase regulatory oversight, impose fines or shut down our operations, depending upon the assessment of the severity of the situation. Revised security and safety requirements promulgated by these agencies could necessitate substantial capital and other expenditures. In addition, we must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. Government contracts. Government contract laws and regulations affect how we do business with our customers and, in some instances, impose added

Table of Contents

costs on our business. A violation of specific laws and regulations could result in the imposition of fines and penalties or the termination of our contracts or debarment from bidding on contracts.

Limitations or modifications to indemnification regulations of the U.S. or foreign countries could adversely affect our business.

The Price-Anderson Act partially indemnifies the nuclear industry against liability arising from nuclear incidents in the U.S., while ensuring compensation for the general public. The Price-Anderson Act comprehensively regulates the manufacture, use and storage of radioactive materials, while promoting the nuclear industry by offering broad indemnification to commercial nuclear power plant operators and DOE contractors. Because we provide nuclear fabrication and other services to the DOE relating to its nuclear devices, facilities and other programs and the nuclear power industry in the ongoing maintenance and modifications of its nuclear power plants, including the manufacture of equipment and other components for use in such nuclear power plants, we may be entitled to some of the indemnification protections under the Price-Anderson Act against liability arising from nuclear incidents in the U.S. The indemnification authority under the Price-Anderson Act was extended through December 2025 by the Energy Policy Act of 2005. We also provide nuclear fabrication and other services to the nuclear power industry in Canada and other countries. Canada's Nuclear Liability and Compensation Act generally conforms to international conventions and is conceptually similar to the Price-Anderson Act in the U.S. Accordingly, indemnification protections and the possibility of exclusions under Canada's Nuclear Liability and Compensation Act are similar to those under the Price-Anderson Act in the U.S.

The Price-Anderson Act's and Canada's Nuclear Liability and Compensation Act's indemnification provisions may not apply to all liabilities that we might incur while performing services as a contractor for the DOE and the nuclear power industry. If an incident or evacuation is not covered under the Price-Anderson Act's or Canada's Nuclear Liability and Compensation Act's indemnification provisions, we could be held liable for damages, regardless of fault, which could have an adverse effect on our results of operations and financial condition. In connection with the international transportation of toxic, hazardous and radioactive materials, it is possible for a claim to be asserted which may not fall within the indemnification provided by the Price-Anderson Act or Canada's Nuclear Liability and Compensation Act. If such indemnification authority is not applicable in the future, our business could be adversely affected if the owners and operators of nuclear power plants fail to retain our services in the absence of commercially adequate insurance and indemnification.

Moreover, because we manufacture nuclear components for the U.S. Government's defense program, we may be entitled to some of the indemnification protections afforded by Public Law 85-804 for certain of our nuclear operations risks. Public Law 85-804 authorizes certain agencies of the U.S. Government, such as the DOE and the U.S. Department of Defense, to indemnify their contractors against unusually hazardous or nuclear risks when such action would facilitate the national defense. However, because the indemnification protections afforded by Public Law 85-804 are granted on a discretionary basis, situations could arise where the U.S. Government elects not to offer such protections. In such situations, our business could be adversely affected by either our inability to obtain commercially adequate insurance or indemnification or our refusal to pursue such operations in the absence of such protections.

Our operations involve the handling, transportation and disposal of radioactive and hazardous materials, and environmental laws and regulations and civil liability for contamination of the environment or related personal injuries may result in increases in our operating costs and capital expenditures and decreases in our earnings and cash flows.

Our operations involve the handling, transportation and disposal of radioactive and hazardous materials, including nuclear devices and their components. Failure to properly handle these materials could pose a health risk to humans or wildlife and could cause personal injury and property damage (including environmental contamination). If an accident were to occur, its severity could be significantly affected by the volume of the materials and the speed of corrective action taken by emergency response personnel, as well as other factors beyond our control, such as weather and wind conditions. Actions taken in response to an accident could result in significant costs.

Governmental requirements relating to the protection of the environment, including solid waste management, air quality, water quality, the decontamination and decommissioning of nuclear manufacturing and processing facilities and cleanup of contaminated sites, have had a substantial impact on our operations. These requirements are complex and subject to frequent change. In some cases, they can impose liability for the entire cost of cleanup on any responsible party without regard to negligence or fault and impose liability on us for the conduct of others or conditions others have caused, or for our acts that complied with all applicable requirements when we performed them. Our compliance with amended, new or more stringent requirements, stricter interpretations of existing requirements or the future discovery of contamination may require us to make material expenditures or subject us to liabilities that we currently do not anticipate. Such expenditures and liabilities may adversely affect our business, financial condition, results of operations and cash flows. In addition, some of our operations and

Table of Contents

the operations of predecessor owners of some of our properties have exposed us to civil claims by third parties for liability resulting from alleged contamination of the environment or personal injuries caused by releases of hazardous substances into the environment. See "Business - Governmental Regulations and Environmental Matters."

In our contracts, we seek to protect ourselves from liability associated with accidents, but there can be no assurance that such contractual limitations on liability will be effective in all cases or that our or our customers' insurance will cover all the liabilities we have assumed under those contracts. The costs of defending against a claim arising out of a nuclear incident or precautionary evacuation, and any damages awarded as a result of such a claim, could adversely affect our results of operations and financial condition.

We maintain insurance coverage as part of our overall risk management strategy and due to requirements to maintain specific coverage in our financing agreements and in many of our contracts. These policies do not protect us against all liabilities associated with accidents or for unrelated claims. In addition, comparable insurance may not continue to be available to us in the future at acceptable prices, or at all.

We are subject to domestic and international laws and regulations, violations of which may adversely affect our future operations.

Many aspects of our operations and properties are affected by political developments and are subject to both domestic and foreign governmental regulations, including those relating to:


•	constructing and manufacturing nuclear components;


•	currency conversions and repatriation;


•	environmental protection legislation;


•	export control;


•	taxation of earnings;


•	transactions in or with certain foreign countries or officials, such as those designated by the Office of Foreign Assets Control of the U.S. Department of the Treasury; and


•	use of local employees and suppliers.

Failure by us, our sales representatives, or consultants to comply with these laws and regulations could result in administrative, civil, or criminal liabilities and could, in the extreme case, result in suspension or debarment from government contracts or suspension of our export privileges, which could have a material adverse effect on our business.

In addition, a portion of the demand for our products and services is from electric power generating companies and other customers. The demand for power generation products and services can be influenced by state and federal governmental legislation setting requirements for utilities related to operations, emissions and environmental impacts. The legislative process is unpredictable and includes a platform that continuously seeks to increase the restrictions on power producers.

We cannot determine the extent to which our future operations and earnings may be affected by new legislation, new regulations or changes in existing regulations.

Our business requires us to obtain, and to comply with, national, state and local government permits and approvals.

Our business is required to obtain, and to comply with, national, state and local government permits and approvals. Any of these permits or approvals may be subject to denial, revocation or modification under various circumstances. Failure to obtain or comply with the conditions of permits or approvals may adversely affect our operations by temporarily suspending our activities or curtailing our work and may subject us to penalties and other sanctions. Although existing licenses are routinely renewed by various regulators, renewal could be denied or jeopardized by various factors, including:


•	failure to provide adequate financial assurance for decommissioning or closure;


•	failure to comply with environmental and safety laws and regulations or permit conditions;


•	local community, political or other opposition;

Table of Contents


•	executive action; and


•	legislative action.

In addition, if new environmental legislation or regulations are enacted or implemented, or existing laws or regulations are amended or are interpreted or enforced differently, we may be required to obtain additional operating permits or approvals. Our inability to obtain, and to comply with, the permits and approvals required for our business could have a material adverse effect on us.

Employee, agent or partner misconduct or our overall failure to comply with laws, regulations or government contracts could weaken our ability to win contracts, lead to the suspension of our operations and result in reduced revenues and profits.

Misconduct, fraud, or other improper activities by one or more of our employees, agents or partners as well as our failure to comply with applicable laws and regulations, could have a significant negative impact on our business and reputation. Such misconduct could include the failure to comply with government procurement regulations, regulations regarding the protection of classified information, regulations regarding the pricing of labor and other costs in government contracts, regulations on lobbying or similar activities, regulations pertaining to the internal controls over financial reporting and various other applicable laws or regulations. For example, we regularly provide services that may be highly sensitive or that are related to critical national security matters; if a security breach were to occur, our ability to procure future government contracts could be severely limited. The precautions we take to prevent and detect these activities may not be effective, and we could face unknown risks or losses.

We are routinely audited and reviewed by the U.S. Government and its agencies. These agencies review our performance under our contracts, our cost structure and our compliance with applicable laws, regulations and standards, as well as the adequacy of, and our compliance with, our internal control systems and policies. Systems that are subject to review include our purchasing systems, billing systems, property management and control systems, cost estimating systems, compensation systems and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. If an audit or review uncovers improper or illegal activities, we could be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines, loss of security clearance and suspension or debarment from contracting with the U.S. Government. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us.

We conduct a portion of our operations through joint venture entities, over which we may have limited ability to influence.

We currently have equity interests in several joint ventures and may enter into additional joint venture arrangements in the future. Our influence over some of these entities may be limited. Even in those joint ventures over which we do exercise significant influence, we are often required to consider the interests of our joint venture partners in connection with major decisions concerning the operations of the joint ventures. In any case, differences in views among the joint venture participants may result in delayed decisions or disputes. We also cannot control the actions of our joint venture participants. We sometimes have joint and several liabilities with our joint venture partners under the applicable contracts for joint venture projects and we cannot be certain that our partners will be able to satisfy any potential liability that could arise. These factors could potentially harm the business and operations of a joint venture and, in turn, our business and operations.

Operating through joint ventures in which we are minority holders results in us having limited control over many decisions made with respect to projects and internal controls relating to projects. These joint ventures may not be subject to the same requirements regarding internal controls and internal control over financial reporting that we follow. As a result, internal control problems may arise with respect to the joint ventures that could adversely affect our ability to respond to requests or contractual obligations to customers or to meet the internal control requirements to which we are otherwise subject.

In addition, our arrangements involving joint ventures may restrict us from gaining access to the cash flows or assets of these entities. In some cases, our joint ventures have governmentally imposed restrictions on their abilities to transfer funds to us.

Table of Contents

If our co-venturers fail to perform their contractual obligations on a project or if we fail to coordinate effectively with our co-venturers, we could be exposed to legal liability, loss of reputation and reduced profit on the project.

We often perform projects jointly with third parties. For example, we enter into contractual arrangements to bid for and perform jointly on large projects. Success on these joint projects depends in part on whether our co-venturers fulfill their contractual obligations satisfactorily. If any one or more of these third parties fail to perform their contractual obligations satisfactorily, we may be required to make additional investments and provide added services in order to compensate for that failure. If we are unable to adequately address any such performance issues, then our customer may exercise its right to terminate a joint project, exposing us to legal liability, loss of reputation and reduced profit.

Our collaborative arrangements also involve risks that participating parties may disagree on business decisions and strategies. These disagreements could result in delays, additional costs and risks of litigation. Our inability to successfully maintain existing collaborative relationships or enter into new collaborative arrangements could have a material adverse effect on our results of operations.

The loss of the services of one or more of our key personnel, or our failure to attract, assimilate and retain trained personnel in the future, could disrupt our operations and result in loss of revenues.

Our success depends on the continued active participation of our executive officers and key operating personnel. The unexpected loss of the services of any one of these persons could adversely affect our operations.

Our operations require the services of employees having the technical training and experience necessary to obtain the proper operational results. Certain of our operations also require personnel who are eligible to obtain and maintain U.S. Government security clearances. As such, our operations depend, to a considerable extent, on the continuing availability of such employees and personnel. Additionally, the process of obtaining the requisite security clearances for some of our personnel can be subject to delays and other factors beyond our control. If we should suffer any material loss of personnel to competitors, retirement or other reasons, or experience difficulties employing additional or replacement personnel with the requisite level of training, experience and qualifications to adequately operate our business, our operations could be adversely affected.

While we believe our wage rates are competitive and our relationships with our employees are satisfactory, a significant increase in the wages paid by other employers could result in a reduction in our workforce, increases in wage rates, or both.

We may be unable to realize expected benefits from our restructuring and margin improvement actions, and our profitability or our business otherwise might be adversely affected.

Our restructuring and margin improvement activities are intended to generate operating expense savings through direct and indirect overhead expense reductions as well as other savings. We continue to focus on structural changes in our operating model to drive significant margin improvement. These types of cost reduction and restructuring activities are complex. If we do not successfully manage our current restructuring activities, or any other restructuring activities that we may undertake in the future, expected efficiencies and benefits might be delayed or not realized, and our operations and business could be disrupted. Risks associated with these actions and other workforce management issues include delays, additional unexpected costs, implementation cost overruns, changes in restructuring plans that increase or decrease the number of employees affected, adverse effects on employee morale and the failure to meet operational targets due to the loss of employees, any of which may impair our ability to achieve anticipated cost reductions or may otherwise harm our business, which could have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

Negotiations with labor unions and possible work stoppages and other labor problems could divert management's attention and disrupt operations. In addition, new collective bargaining agreements or amendments to agreements could increase our labor costs and operating expenses.

A significant number of our employees are members of labor unions. If we are unable to negotiate acceptable new contracts with our unions from time to time, we could experience strikes or other work stoppages by the affected employees. If any such strikes or other work stoppages were to occur, we could experience a significant disruption of operations. In addition, negotiations with unions could divert management attention. New union contracts could result in increased operating costs, as a result of higher wages or benefit expenses, for both union and nonunion employees. If nonunion employees were to unionize, we would experience higher ongoing labor costs.

Table of Contents

Pension and medical expenses associated with our retirement benefit plans may fluctuate significantly depending on changes in actuarial assumptions, future market performance of plan assets, future trends in health care costs and legislative or other regulatory actions.

A substantial portion of our current and retired employee population is covered by pension and postretirement benefit plans, the costs and funding requirements of which depend on our various assumptions, including estimates of rates of return on benefit-related assets, discount rates for future payment obligations, rates of future cost growth, mortality assumptions and trends for future costs. Service accruals for salaried participants ceased as of December 31, 2015. Variances from these estimates could have a material adverse effect on us. In addition, our policy to recognize these variances annually through mark to market accounting could result in volatility in our results of operations, which could be material. As of December 31, 2016, our defined benefit pension and postretirement benefit plans were underfunded by approximately $374.0 million. A substantial portion of our postretirement benefit plan costs are recoverable on our U.S. Government contracts. See Note 8 to the consolidated financial statements included in this annual report for additional information regarding our pension and postretirement benefit plan obligations.

Our internal controls over financial reporting may not be sufficient to achieve all stated goals and objectives.

Our internal controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. The design of any system of internal controls and procedures is based in part upon various assumptions about the likelihood of future events, and we cannot provide assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Our Nuclear Operations segment relies on several single-source suppliers, which could, under certain circumstances, adversely affect our revenues and operating results.

Our Nuclear Operations segment relies on several single-source suppliers for materials used in its products. If the supply of a single-sourced material is delayed or ceases, we may not be able to produce the related product in a timely manner or in sufficient quantities, if at all, which could adversely affect our revenues and operating results. In addition, a single-source supplier of a key component could potentially exert significant bargaining power over price, quality, warranty claims, or other terms relating to the single-sourced materials.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act.

The U.S. Foreign Corrupt Practices Act (the "FCPA") generally prohibits companies and their intermediaries from making improper payments to non-U.S. officials. Our training program and policies mandate compliance with the FCPA. We operate in some parts of the world that have experienced governmental corruption to some degree, and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. If we are found to be liable for violations of the FCPA (either due to our own acts or our inadvertence, or due to the acts or inadvertence of others, including employees of our joint ventures), we could suffer from civil and criminal penalties or other sanctions.

We may not be able to compete successfully against current and future competitors.

Some of our competitors or potential competitors have greater financial or other resources than we have and in some cases are government supported. Our operations may be adversely affected if our current competitors or new market entrants introduce new products or services with better features, performance, prices or other characteristics than those of our products and services. Furthermore, we operate in industries where capital investment is critical. We may not be able to obtain as much purchasing and borrowing leverage and access to capital for investment as other public companies, which may impair our ability to compete against competitors or potential competitors.

Our international operations are subject to political, economic and other uncertainties not generally encountered in our domestic operations.

We derive a portion of our revenues from international operations. Operating in international markets requires significant resources and management attention and subjects us to political, economic and regulatory risks that are not generally encountered in our U.S. operations. These include:


•	renegotiation or nullification of our existing contracts;

Table of Contents


•	changing political conditions and changing laws and policies affecting trade and investment; and


•	changes in foreign currency exchange rates.

Our international operations sometimes face the additional risks of fluctuating currency values, hard currency shortages and controls of foreign currency exchange.

Natural disasters or other events beyond our control could adversely impact our business.

Natural disasters, such as earthquakes, tsunamis, hurricanes, floods, tornados, or other events could adversely impact demand for or supply of our products. In addition, natural disasters could also cause disruption to our facilities, systems or projects, which could interrupt operational processes and performance on our contracts and adversely impact our ability to manufacture our products and provide services and support to our customers. We operate facilities in areas of the world that are exposed to natural disasters, such as, but not limited to, hurricanes, floods and tornados.

War, other armed conflicts or terrorist attacks could have a material adverse effect on our business.

War, terrorist attacks and unrest have caused and may continue to cause instability in the world's financial and commercial markets and have significantly increased political and economic instability in some of the geographic areas in which we operate. Threats of war or other armed conflict may cause further disruption to financial and commercial markets. In addition, continued unrest could lead to acts of terrorism in the U.S. or elsewhere, and acts of terrorism could be directed against companies such as ours. Also, acts of terrorism and threats of armed conflicts in or around various areas in which we operate could limit or disrupt our markets and operations, including disruptions from evacuation of personnel, cancellation of contracts or the loss of personnel or assets. Armed conflicts, terrorism and their effects on us or our markets may significantly affect our business and results of operations in the future.

Risks Relating to the Spin-Off of Our Former Power Generation Business

Potential indemnification liabilities relating to the spin-off could materially adversely affect us.

In connection with the spin-off, we entered into agreements with BWE to provide for, among other things, the principal corporate transactions required to effect the planned spin-off, certain conditions to the spin-off and provisions governing the relationship between us and BWE with respect to and resulting from the spin-off. Among other things, these agreements provided for indemnification obligations designed to make us financially responsible for substantially all liabilities that may exist relating to our business activities, whether incurred prior to or after the spin-off. If we are required to indemnify BWE, we may be subject to substantial liabilities.

BWE agreed to indemnify us for certain liabilities in connection with the spin-off. However, there can be no assurance that the indemnity will be sufficient to insure us against the full amount of such liabilities, or that BWE will be able to satisfy its indemnification obligations.

In connection with the spin-off, BWE agreed to indemnify us for certain liabilities. However, third parties could seek to hold us responsible for any of the liabilities that BWE will agree to retain, and there can be no assurance that the indemnity from BWE will be sufficient to protect us against the full amount of such liabilities, or that BWE will be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from BWE any amounts for which we are held liable, we may be temporarily required to bear these losses.

The BWE spin-off could result in substantial tax liability.

Upon completion of the spin-off, we received an opinion of counsel substantially to the effect that, for U.S. federal income tax purposes, the spin-off will qualify under Section 355 of the Code and certain transactions related to the spin-off will qualify under Sections 355 and/or 368 of the Code. The opinion relied on, among other things, various assumptions and representations as to factual matters made by us and BWE, which, if inaccurate or incomplete in any material respect, could jeopardize the conclusions reached by such counsel in its opinion. The opinion is not binding on the IRS or the courts, and there can be no assurance that the IRS or the courts will not challenge the conclusions stated in the opinion or that any such challenge would not prevail.

We are not aware of any facts or circumstances that would cause the assumptions or representations that were relied on in the opinion to be inaccurate or incomplete in any material respect. If, notwithstanding receipt of the opinion, the spin-off were subsequently determined not to qualify under Section 355 of the Code, each U.S. holder of our common stock who receives

Table of Contents

shares of BWE common stock in the spin-off would generally be treated as receiving a taxable distribution of property in an amount equal to the fair market value of the shares of BWE common stock received. That distribution would be taxable to each such stockholder as a dividend to the extent of our current and accumulated earnings and profits. For each such stockholder, any amount that exceeded our earnings and profits would be treated first as a non-taxable return of capital to the extent of such stockholder's tax basis in its shares of our common stock with any remaining amount being taxed as a capital gain. In addition, if certain related preparatory transactions were to fail to qualify for tax-free treatment, they would be treated as taxable sales and/or distributions to the Company.

We entered into a tax sharing agreement with BWE in connection with the spin-off. Pursuant to this agreement, we agreed with BWE on the allocation of spin-off related tax liabilities and the indemnification provisions relating to these liabilities. If we are liable for taxes under the tax sharing agreement, that liability could have a material adverse effect on us. Additionally, there can be no assurance that any indemnities from BWE will be sufficient to protect us against any potential tax liabilities.

Risks Relating to our Spin-Off from McDermott International, Inc.

We are subject to continuing contingent liabilities of MII as a result of our spin-off from MII.

With completion of our spin-off from McDermott International, Inc. ("MII") in 2010 ("the MII spin-off"), there are several significant areas where the liabilities of MII may become our obligations. For example, under the Internal Revenue Code of 1986, as amended (the "Code") and the related rules and regulations, each corporation that was a member of our consolidated tax reporting group during any taxable period or portion of any taxable period ending on or before the effective time of the spin-off is jointly and severally liable for the federal income tax liability of our entire consolidated tax reporting group for that taxable period. We have entered into a tax sharing agreement with a subsidiary of MII that allocates the responsibility for prior period taxes of our consolidated tax reporting group between us and MII and its subsidiaries. However, if the subsidiary of MII were unable to pay, we could be required to pay the entire amount of such taxes. Other provisions of federal law establish similar liability for other matters, including laws governing tax-qualified pension plans as well as other contingent liabilities.

Our spin-off from MII could result in substantial tax liability.

MII obtained a private letter ruling from the IRS substantially to the effect that, for U.S. federal income tax purposes, the spin-off qualified under Section 355 of the Code and certain transactions related to the MII spin-off qualified under Sections 355 and/or 368 of the Code. If the factual assumptions or representations made in the private letter ruling request are inaccurate or incomplete in any material respect, then we will not be able to rely on the ruling. Furthermore, the IRS will not rule on whether a distribution such as the MII spin-off satisfies certain requirements necessary to obtain tax-free treatment under Section 355 of the Code. Rather, the private letter ruling is based on representations by MII that those requirements have been satisfied, and any inaccuracy in those representations could invalidate the ruling.

Under the terms of the tax sharing agreement we entered into in connection with the MII spin-off, we are generally responsible for any taxes imposed on us or MII and its subsidiaries in the event that the MII spin-off and/or certain related preparatory transactions were to fail to qualify for tax-free treatment. However, if the MII spin-off and/or certain related preparatory transactions were to fail to qualify for tax-free treatment because of actions or failures to act by MII or its subsidiaries, a subsidiary of MII would be responsible for all such taxes. If we are liable for taxes under the tax sharing agreement, that liability could have a material adverse effect on us. The tax sharing agreement expired in September 2016.

Potential indemnification liabilities to MII pursuant to the master separation agreement could materially adversely affect our company.

The master separation agreement with MII provides for, among other things, the principal corporate transactions required to effect the MII spin-off, certain conditions to the MII spin-off and provisions governing the relationship between our company and MII with respect to and resulting from the MII spin-off. Among other things, the master separation agreement provides for indemnification obligations designed to make our company financially responsible for substantially all liabilities that may exist relating to our business activities, whether incurred prior to or after the MII spin-off, as well as those obligations of MII assumed by us pursuant to the master separation agreement. If we are required to indemnify MII under the circumstances set forth in the master separation agreement, we may be subject to substantial liabilities.

Table of Contents

In connection with our separation from MII, MII will indemnify us for certain liabilities. However, there can be no assurance that the indemnity will be sufficient to insure us against the full amount of such liabilities, or that MII's ability to satisfy its indemnification obligation will not be impaired in the future.

Pursuant to the master separation agreement, MII has agreed to indemnify us for certain liabilities. However, third parties could seek to hold us responsible for any of the liabilities that MII has agreed to retain, and there can be no assurance that the indemnity from MII will be sufficient to protect us against the full amount of such liabilities, or that MII will be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from MII any amounts for which we are held liable, we may be temporarily required to bear these losses, which could have a material adverse effect on our liquidity.

Risks Relating to Ownership of Our Common Stock

Provisions in our corporate documents and Delaware law could delay or prevent a change in control of our company, even if that change may be considered beneficial by some stockholders.

The existence of some provisions of our certificate of incorporation and bylaws and Delaware law could discourage, delay or prevent a change in control of our company that a stockholder may consider favorable. These include provisions:


•	providing that our Board of Directors fixes the number of members of the board;


•	providing for the division of our Board of Directors into three classes with staggered terms;


•	limiting who may call special meetings of stockholders;


•	prohibiting stockholder action by written consent, thereby requiring stockholder action to be taken at a meeting of the stockholders;


•	establishing advance notice requirements for nominations of candidates for election to our Board of Directors or for proposing matters that can be acted on by stockholders at stockholder meetings;


•	establishing supermajority vote requirements for certain amendments to our certificate of incorporation and bylaws;


•	limiting the right of stockholders to remove directors;


•	authorizing a large number of shares of common stock that are not yet issued, which would allow our Board of Directors to issue shares to persons friendly to current management, thereby protecting the continuity of our management, or which could be used to dilute the stock ownership of persons seeking to obtain control of us; and


•	authorizing the issuance of "blank check" preferred stock, which could be issued by our Board of Directors to increase the number of outstanding shares and thwart a takeover attempt.

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an anti-takeover effect with respect to transactions not approved in advance by our Board of Directors, including discouraging takeover attempts that might result in a premium over the market price for shares of our common stock.

We believe these provisions protect our stockholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with our Board of Directors and by providing our Board of Directors with more time to assess any acquisition proposal, and are not intended to make our company immune from takeovers. However, these provisions apply even if the offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our Board of Directors determines is not in the best interests of our company and our stockholders.

We may issue preferred stock that could dilute the voting power or reduce the value of our common stock.

Our certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designation, powers, preferences and relative, participating, optional and other special rights, including preferences over our common stock respecting dividends and distributions, as our Board of Directors generally may determine. The terms of one or more classes or series of preferred stock could dilute the voting power or reduce the value of our common stock. For example, we could grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we could assign to holders of preferred stock could affect the residual value of the common stock.

The Lynchburg, Virginia facility is our Nuclear Operations segment’s primary manufacturing plant and is the nation’s largest commercial high-enriched uranium processing facility. The site is subject to review by the NRC for licensee performance. The performance review determines the safe and secure conduct of operations of the facility. The site is also the largest commercial International Atomic Energy Agency certified facility in the U.S.

(2)

We acquired the Euclid facilities through a bond/lease transaction facilitated by the Cleveland Cuyahoga County Port Authority (the "Port"), whereby we acquired a ground parcel and the Port issued bonds, the proceeds of which were used to acquire, improve and equip the facilities, including the acquisition of the larger facility and a 40-year prepaid ground lease for the smaller facility. We are leasing the facilities from the Port with an expiration date of 2019 but subject to certain extension options.

(3)

The Peterborough and Toronto leases were entered into as part of the acquisition of NEC. These facilities operate under a Class 1B Nuclear Fuel Facility Operating License renewed by the Canadian Nuclear Safety Commission to fabricate natural uranium fuel. We are leasing the facilities from an affiliate of one of the former owners of GEH-C for a period of 20 years subject to certain extension options.

We consider each of our significant properties to be suitable and adequate for its intended use.

On June 30, 2015, we completed the spin-off of BWE. Prior to the completion of the spin-off, there were two concurrent markets in which to trade our common stock: a "regular way" market and an "ex-distribution" market. Shares of our common stock that traded in the "regular way" market traded with an entitlement to shares of BWE common stock. Shares that traded in the "ex-distribution" market traded without an entitlement to shares of BWE common stock. On June 30, 2015, the closing price of our common stock traded in the "regular way" market on the NYSE was $32.80. On June 30, 2015, the closing price of our common stock traded in the "ex-distribution" market on the NYSE was $23.45. The share prices prior to the spin-off have not been adjusted to reflect the distribution of the BWE shares.

On November 8, 2013, our Board of Directors approved a quarterly cash dividend of $0.10 per share. On July 31, 2015, subsequent to the spin-off of BWE, our Board of Directors elected to modify its previously approved quarterly cash dividend to $0.06 per share. On February 23, 2016, our Board of Directors declared an increase to its previously approved quarterly cash dividend to $0.09 per share. Our ability to pay dividends may be limited by certain restrictions in our credit agreement and by applicable law. Our Board of Directors will continue to evaluate our cash dividend policy from time to time.

As of February 23, 2017, there were approximately 2,052 record holders of our common stock.

The following table provides information on our equity compensation plans as of December 31, 2016:

In November 2012, we announced that a share repurchase program was authorized by our Board of Directors. The following table provides information on our purchases of equity securities during the quarter ended December 31, 2016. Any shares purchased that were not part of a publicly announced plan or program are related to repurchases of common stock pursuant to the provisions of employee benefit plans that permit the repurchase of shares to satisfy statutory tax withholding obligations.

On September 15, 2016, the Company entered into a $200 million accelerated share repurchase agreement (the "ASR Agreement") with Wells Fargo Bank, National Association ("Wells Fargo"). Pursuant to the terms of the ASR Agreement, on September 16, 2016, the Company paid Wells Fargo $200 million in cash and received 4,135,435 shares of the Company’s common stock. The final number of shares to be repurchased will be based on the volume-weighted average stock price of the Company’s common stock during the term of the ASR Agreement, less a customary discount. At settlement, under certain circumstances, Wells Fargo may be required to deliver additional shares of common stock to the Company, or under certain circumstances, the Company may be required to deliver shares of common stock or to make a cash payment, at its election, to Wells Fargo.

Item 7.	MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Statements we make in the following discussion, which express a belief, expectation or intention, as well as those that are not historical fact, are forward-looking statements that are subject to risks, uncertainties and assumptions. Our actual results, performance or achievements, or industry results, could differ materially from those we express in the following discussion as a result of a variety of factors, including the risks and uncertainties we have referred to under the headings "Cautionary Statement Concerning Forward-Looking Statements" and "Risk Factors" in Items 1 and 1A of Part I of this report.

GENERAL

We are a leading supplier of nuclear components and fuel to the U.S. Government; provide technical, management and site services to support governments in the operation of complex facilities and environmental remediation activities; and supply precision manufactured components, nuclear fuel and services for the commercial nuclear power industry. In general, we operate in capital-intensive industries and rely on large contracts for a substantial amount of our revenues. We are currently exploring growth strategies across our segments through acquisitions to expand and complement our existing businesses. We would expect to fund these opportunities with cash on hand or by raising additional capital through debt, equity or some combination thereof.

We operate in three reportable segments: Nuclear Operations, Technical Services and Nuclear Energy. Prior to 2015, our mPower business was considered a separate reportable segment; however, in accordance with FASB Topic Segment Reporting, this business no longer meets the quantitative threshold criteria and is now included in our "Other" category.

The results of operations of BWE are presented as discontinued operations on the consolidated statements of income. We have presented the notes to our consolidated financial statements on the bases of continuing operations, unless otherwise stated.

Spin-off of BWE

On June 30, 2015, we completed the spin-off of BWE to our stockholders through a stock distribution. BWE’s assets and business primarily consisted of those that we previously reported as our Power Generation segment. In connection with the spin-off, our stockholders received 100% of the outstanding common stock of BWE. The distribution of BWE common stock occurred by way of a pro rata stock distribution to our stockholders. Our stockholders received one share of BWE common stock for every two shares of our common stock held by such stockholder on June 18, 2015, and cash in lieu of any fractional shares. Prior to the completion of the spin-off, we made a cash payment to BWE totaling $132 million.

In order to effect the distribution and govern our relationship with BWE after the distribution, we entered into a master separation agreement with BWE. In addition to the master separation agreement, we entered into other agreements with BWE in connection with the distribution, including a tax sharing agreement and transition services agreements.

We incurred a total of approximately $66.5 million in total spin-off related costs through June 30, 2015, which includes approximately $29.8 million for professional services and $23.1 million of retention and severance-related charges. The majority of the remaining costs relate to the separation of our facilities and related infrastructure including our information technology systems. Income from discontinued operations for the year ended December 31, 2015 includes $34.4 million of

Table of Contents

these charges and included in continuing operations are spin-off costs of $26.0 million for the year ended December 31, 2015. A total of $6.1 million was recognized in the year ended December 31, 2014.

At the spin-off, we had outstanding performance guarantees for various projects executed by BWE in the normal course of business. These guarantees totaled $1,542 million and have expiration dates from 2015 to 2035. In February 2016, BWE notified us that we have been released from substantially all remaining performances guarantees. Accordingly, we reduced the outstanding liability and recorded a gain of approximately $9.3 million during the year ended December 31, 2016 as a component of other – net in our consolidated statement of income.

Outlook

Nuclear Operations

We expect the backlog of our Nuclear Operations segment of $3,485 million at December 31, 2016 to produce revenues of approximately $1,246 million in 2017, not including any change orders or new contracts that may be awarded during the year.

The revenues of our Nuclear Operations segment are largely a function of defense spending by the U.S. Government. As a supplier of major nuclear components for certain U.S. Government programs, we are a significant participant in the defense industry and have not been negatively impacted by sequestration or federal budget reductions to date. We believe many of our programs are well aligned with national defense and other strategic priorities as we supply high-end equipment for submarines and aircraft carriers for the U.S. Navy. However, it is possible that reductions in federal government spending and sequestration could have an adverse impact on the operating results and cash flows of our Nuclear Operations and Technical Services segments in the future.

We expect that orders for nuclear components will continue to be a significant part of backlog for the foreseeable future. In addition, our Nuclear Operations segment could benefit if the U.S. Government implements recommendations by the U.S. Navy to increase the size of its fleet of ships to include additional submarines and/or aircraft carriers beyond the number included in the U.S. Navy's fiscal year 2016 long-range shipbuilding plan issued on April 3, 2015.

Technical Services

A significant portion of this segment’s operations are conducted through joint ventures, which typically earn fees, and we account for them following the equity method of accounting. See Note 4 to our consolidated financial statements included in this report for financial information on our equity method investments. As a result, this segment reports minimal backlog and revenues.

Given our specialized capabilities of full life-cycle management of special materials, facilities and technologies, we believe our Technical Services segment is well-positioned to continue to participate in the continuing cleanup, operation and management of critical government-owned nuclear sites, laboratories and manufacturing complexes maintained by the DOE, NASA and other federal agencies.

Nuclear Energy

We expect the backlog of our Nuclear Energy segment of $493 million at December 31, 2016 to produce revenues of approximately $197 million in 2017, not including any change orders or new contracts that may be awarded during the year. The revenues in this segment primarily depend on the demand and competitiveness of nuclear energy. The activity of this segment depends on the timing of maintenance outages primarily in the Canadian market and the cyclical nature of capital expenditures and major refurbishments for nuclear utility customers, which could cause variability in our financial results.

Our acquisition of NEC in December 2016 has also expanded our Nuclear Energy segment's product offerings to include nuclear fuel manufacturing and nuclear fuel handling equipment. This acquisition further strengthens the diversity of our service offerings and enhances our ability to support major life extension and refurbishment projects in the commercial nuclear industry.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). Preparing financial statements requires management to make estimates and

Table of Contents

assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are affected by management’s application of accounting policies. We believe the following are our most critical accounting policies that we apply in the preparation of our financial statements. These policies require our most difficult, subjective and complex judgments, often as a result of the need to make estimates of matters that are inherently uncertain.

Contracts and Revenue Recognition. We determine the appropriate accounting method for each of our long-term contracts before work on the project begins. We generally recognize contract revenues and related costs on a percentage-of-completion method for individual contracts or combinations of contracts based on work performed, man hours or a cost-to-cost method, as applicable to the product or activity involved. We recognize estimated contract revenue and resulting income based on the measurement of the extent of progress completion as a percentage of the total project. Certain costs may be excluded from the cost-to-cost method of measuring progress, such as significant costs for materials and major third-party subcontractors, if it appears that such exclusion would result in a more meaningful measurement of actual contract progress and resulting periodic allocation of income. For all contracts, if a current estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full when determined. It is possible that current estimates could materially change for various reasons, including, but not limited to, fluctuations in forecasted labor productivity or steel and other raw material prices. We routinely review estimates related to our contracts, and revisions to profitability are reflected in the quarterly and annual earnings we report. In the years ended December 31, 2016, 2015 and 2014, we recognized net favorable changes in estimate related to long-term contracts accounted for on the percentage-of-completion basis that increased operating income by approximately $31.4 million, $18.6 million and $25.0 million, respectively.

For contracts as to which we are unable to estimate the final profitability except to assure that no loss will ultimately be incurred, we recognize equal amounts of revenue and cost until the final results can be estimated more precisely. For these deferred profit recognition contracts, we recognize revenue and cost equally and only recognize gross margin when probable and reasonably estimable, which we generally determine to be when the contract is approximately 70% complete. We treat long-term construction contracts that contain such a level of risk and uncertainty that estimation of the final outcome is impractical except to assure that no loss will be incurred as deferred profit recognition contracts. We did not enter into any contracts that we have accounted for as deferred profit recognition contracts during 2016, 2015 or 2014.

Our policy is to account for fixed-price contracts under the completed-contract method if we believe that we are unable to reasonably forecast cost to complete at start-up. For example, if we have no experience in performing the type of work on a particular project and are unable to develop reasonably dependable estimates of total costs to complete, we would follow the completed-contract method of accounting for such projects. Generally, our management’s policy is not to enter into fixed-price contracts without an accurate estimate of cost to complete. However, it is possible that in the time between contract execution and the start of work on a project, we could lose confidence in our ability to forecast cost to complete based on intervening events, including, but not limited to, experience on similar projects, civil unrest, strikes and volatility in our expected costs. In such a situation, we would use the completed-contract method of accounting for that project. Under the completed-contract method, income is recognized only when a contract is completed or substantially complete. We did not enter into any contracts that we have accounted for under the completed-contract method during 2016, 2015 or 2014.

Although we continually strive to improve our ability to estimate our contract costs and profitability, adjustments to overall contract costs due to unforeseen events could be significant in future periods. We recognize claims for extra work or for changes in scope of work in contract revenues, to the extent of costs incurred, when we believe collection is probable and can be reasonably estimated. We recognize income from contract change orders or claims when formally agreed with the customer. We regularly assess the collectibility of contract revenues and receivables from customers.

Property, Plant and Equipment. We carry our property, plant and equipment at depreciated cost, reduced by provisions to recognize economic impairment when we determine impairment has occurred. Property, plant and equipment amounts are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset exceeds the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. The amount of the impairment loss to be recorded is calculated by the excess of the asset carrying value over its fair value. Fair value is generally determined using a discounted cash flow analysis. Our estimates of cash flow may differ from actual cash flow due to, among other things, technological changes, economic conditions or changes in operating performance. Any changes in such factors may negatively affect our business segments and result in future asset impairments.

We depreciate our property, plant and equipment using the straight-line method over estimated economic useful lives of eight to 33 years for buildings and three to 14 years for machinery and equipment. We expense the costs of maintenance, repairs and renewals, which do not materially prolong the useful life of an asset, as we incur them.

Investments in Unconsolidated Affiliates. We use the equity method of accounting for affiliates in which our investment ownership ranges from 20% to 50%, unless significant economic or governance considerations indicate that we are unable to exert significant influence, in which case the cost method is used. The equity method is also used for affiliates in which our investment ownership is greater than 50% but we do not have a controlling interest. Currently, all of our material investments in affiliates that are not included in our consolidated results are recorded using the equity method. Affiliates in which our investment ownership is less than 20% and where we are unable to exert significant influence are carried at cost.

Pension Plans and Postretirement Benefits. We utilize actuarial and other assumptions in calculating the cost and benefit obligations of our pension and postretirement benefits. The assumptions utilized in the determination of our benefit cost and obligations include assumptions regarding discount rates, expected returns on plan assets, mortality and health care cost trends. The assumptions utilized represent our best estimates based on historical experience and other factors.

We calculate the majority of our pension costs under both financial accounting standards ("FAS") in accordance with GAAP and cost accounting standards ("CAS") in accordance with the Federal Acquisition Regulation and the related U.S. Government Cost Accounting Standards. We have prepared our consolidated financial statements and segment reporting disclosures utilizing pension costs calculated under FAS. Pension costs calculated under CAS are utilized as the basis for recovery of pension costs on our U.S. Government contracts. For the years ended December 31, 2016, 2015 and 2014, our CAS pension costs attributed to U.S. Government contracts totaled $49.6 million, $57.7 million and $59.7 million, respectively. Pension costs calculated under CAS are recovered on a percentage-of-completion method on the underlying U.S. Government contracts. As a result, the amount of recoverable CAS pension costs recognized as revenue on an annual basis may differ from the amounts noted above. See further discussion of our accounting for contracts and revenue recognition above and in Note 1 to our consolidated financial statements included in this report.

Actual experience that differs from these assumptions or future changes in assumptions will affect our recognized benefit obligations and related costs. We immediately recognize net actuarial gains and losses into earnings in the fourth quarter as a component of net periodic benefit cost. Net actuarial gains and losses occur when actual experience differs from any of the various assumptions used to value our pension and postretirement benefit plans or when assumptions, which are revisited annually through our update of our actuarial valuations, change due to current market conditions or underlying demographic changes. The primary factors contributing to net actuarial gains and losses are changes in the discount rate used to value the obligations as of the measurement date each year, the difference between the actual return on plan assets and the expected return on plan assets and changes in health care cost trends. The effect of changes in the discount rate and expected rate of return on plan assets assumptions in combination with the actual return on plan assets can result in significant changes in our estimated pension and postretirement benefit cost and our consolidated financial condition. Additionally, in the year ended December 31, 2014, we adjusted our mortality assumption to reflect mortality improvements identified by the Society of Actuaries, adjusted for the Company’s experience. The impact of the change in this assumption caused a $70.9 million increase in our pension liability.

Beginning in the first quarter of 2016, we changed the method that we use to estimate the service and interest cost components of our net periodic benefit cost for our pension and postretirement benefit plans. Previously, we estimated interest and service cost utilizing a single weighted-average discount rate derived from the yield curve data used to measure the benefit obligation. Our new method for estimating service and interest cost is a spot rate approach, which utilizes duration specific spot rates from the yield curve that was utilized to measure the benefit obligation. We made this change to provide a more precise estimate of service and interest cost by improving the relationship of the discount rates utilized to measure our benefit obligation and the rates utilized to estimate service and interest cost. This change reduced service and interest cost for the year ended December 31, 2016 compared to our previous method by approximately $11 million. This change does not affect the measurement of our total pension and postretirement benefit obligations or our total net periodic benefit cost as the change in our service and interest cost is offset by our recognized net actuarial (gain) loss. We accounted for this change as a change in accounting estimate, which did not impact previously reported results.

Loss Contingencies. We estimate liabilities for loss contingencies when it is probable that a liability has been incurred and the amount of loss is reasonably estimable. We provide disclosure when there is a reasonable possibility that the ultimate loss will exceed the recorded provision or if such probable loss is not reasonably estimable. We are currently involved in some significant litigation, as discussed in Note 11 to our consolidated financial statements included in this report. We have accrued our estimates of the probable losses associated with these matters. However, our losses are typically resolved over long periods of time and are often difficult to estimate due to the possibility of multiple actions by third parties. Therefore, it is possible that future earnings could be affected by changes in our estimates related to these matters.

Goodwill and Intangible Assets. Each year, we evaluate goodwill at each reporting unit to assess recoverability, and impairments, if any, are recognized in earnings. We perform a qualitative analysis when we believe that there is sufficient excess fair value over carrying value based on our most recent quantitative assessment, adjusted for relevant facts and circumstances that could affect fair value. Deterioration in macroeconomic, industry and market conditions, cost factors, overall financial performance, share price decline or entity and reporting unit specific events could cause us to believe a qualitative test is no longer appropriate.

When we determine that it is appropriate to test goodwill for impairment utilizing a quantitative test, the first step of the test compares the fair value of a reporting unit to its carrying amount, including goodwill. We utilize both the income and market valuation approaches to provide inputs into the estimate of the fair value of our reporting units, which would be considered by market participants.

Table of Contents

Under the income valuation approach, we employ a discounted cash flow model to estimate the fair value of each reporting unit. This model requires the use of significant estimates and assumptions regarding future revenues, costs, margins, capital expenditures, changes in working capital, terminal year growth rate and cost of capital. Our cash flow models are based on our forecasted results for the applicable reporting units. Actual results could differ materially from our projections. Some assumptions, such as future revenues, costs and changes in working capital are company driven and could be affected by a loss of one or more significant contracts or customers, failure to control costs on certain contracts; a decline in U.S. Government funding or a decline in demand based on changing economic or regulatory conditions. Changes in external market conditions may affect certain other assumptions, such as the cost of capital. Market conditions can be volatile and are outside of our control.

Under the market valuation approach, we employ the guideline publicly traded company method, which indicates the fair value of the equity of each reporting unit by comparing it to publicly traded companies in similar lines of business. After identifying and selecting guideline companies, we analyze their business and financial profiles for relative similarity. Factors such as size, growth, risk and profitability are analyzed and compared to each of our reporting units. Assumptions include the selection of our peer companies and use of market multiples, which could deteriorate or increase based on the profitability of our competitors and performance of their stock, which is often dependent on the performance of the stock market and general economy as a whole.

Adverse changes in these assumptions utilized within the first step of our impairment test could cause a reduction or elimination of excess fair value over carrying value, resulting in potential recognition of impairment. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of the impairment loss, if any. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill.

We completed our annual review of goodwill for each of our reporting units for the year ended December 31, 2016, which indicated that we had no impairment of goodwill. The fair value of our reporting units was substantially in excess of carrying value.

Each year, we evaluate indefinite lived intangible assets to assess recoverability, and impairments, if any, are recognized in earnings. We perform a qualitative assessment when testing indefinite lived intangible assets for impairment to determine whether events or circumstances that could affect the significant inputs used in determining fair value have occurred that indicate that it is more likely than not that the indefinite lived intangible asset is impaired. Deterioration in macroeconomic, industry and market conditions, cost factors or overall financial performance could cause us to believe a qualitative test is no longer appropriate. When quantitative assessments are performed, we primarily utilize income-based valuation approaches. Under the income-based valuation approach, we employ a relief from royalty method of valuation. This method requires significant assumptions, including assumed royalty rate, future revenues and cost of capital. Assumptions related to operating performance, such as future revenues, could be affected by loss of a customer contract, a decline in U.S. Government funding or a decline in demand based on changing economic or regulatory conditions. Changes in external market conditions may affect certain other assumptions, such as the cost of capital. Market conditions can be volatile and are outside of our control.

Adverse changes in these assumptions utilized within our indefinite lived intangible asset impairment test could cause a reduction or elimination of excess fair value over carrying value, resulting in potential recognition of impairment.

We have completed our annual review of our indefinite lived intangible assets for the year ended December 31, 2016, which indicated that we had no impairment. The fair value of our indefinite lived intangible assets was substantially in excess of carrying value.

Asset Retirement Obligations and Environmental Clean-up Costs. We accrue for future decommissioning of our nuclear facilities that will permit the release of these facilities to unrestricted use at the end of each facility’s life, which is a requirement of our licenses from the NRC and the CNSC. In accordance with the FASB Topic Asset Retirement and Environmental Obligations, we record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. In estimating fair value, we use present value of cash flows expected to be incurred in settling our obligations. To the extent possible, we perform a marketplace assessment of the cost and timing of performing the retirement activities. We apply a credit-adjusted risk-free interest rate to our expected cash flows in our determination of fair value. When we initially record such a liability, we capitalize a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of a liability, we will settle the obligation for its recorded amount or incur a gain or loss. This topic applies to environmental liabilities associated with assets that we currently operate and are obligated to remove from service. For environmental liabilities associated with assets that we no longer operate, we have accrued amounts based on the estimated

costs of clean-up activities, net of the anticipated effect of any applicable cost-sharing arrangements. We adjust the estimated costs as further information develops or circumstances change. An exception to this accounting treatment relates to the work we perform for two facilities for which the U.S. Government is obligated to pay substantially all the decommissioning costs.

Income Taxes. Income tax expense for federal, foreign, state and local income taxes are calculated on pre-tax income based on current tax law and includes the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. We assess deferred taxes and the adequacy of the valuation allowance on a quarterly basis. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. We record interest and penalties (net of any applicable tax benefit) related to income taxes as a component of provision for income taxes on our consolidated statements of income.

We would be subject to withholding taxes if we were to distribute earnings from certain foreign subsidiaries, and unrecognized deferred income tax liabilities, including withholding taxes, would be payable upon distribution of these earnings. We consider the earnings of our non-U.S. subsidiaries to be permanently reinvested.

Stock-Based Compensation. We account for stock-based compensation in accordance with FASB Topic Compensation – Stock Compensation. Under the fair value recognition provisions of this statement, the cost of employee services received in exchange for an award of equity instruments is measured at the grant date based on the fair value of the award. Stock-based compensation expense is recognized on a straight-line basis over the requisite service periods of the awards, which is generally equivalent to the vesting term. We use a Black-Scholes option pricing model to determine the fair value of certain share-based awards, such as stock options and stock appreciation rights. The determination of the fair value of a share-based payment award using an option-pricing model requires the input of highly subjective assumptions, such as the expected life of the award and stock price volatility. For liability-classified awards, such as cash-settled restricted stock units and performance units, fair values are determined at grant date using the closing price of our common stock and are remeasured at the end of each reporting period through the date of settlement.

Business Combinations. We account for acquisitions in accordance with FASB Topic Business Combinations. This topic broadens the fair value measurements and recognition of assets acquired, liabilities assumed and interests transferred as a result of business combinations. It also provides disclosure requirements to assist users of the financial statements in evaluating the nature and financial effects of business combinations.

For further discussion of recently adopted accounting standards, see Note 1 to our consolidated financial statements included in this report.

Consolidated Results of Operations

Year Ended December 31, 2016 vs. 2015

Consolidated revenues increased 9.5%, or $135.0 million, to $1,550.6 million in the year ended December 31, 2016 compared to $1,415.5 million for the corresponding period of 2015, due to increases in revenues from our Nuclear Operations, Technical Services and Nuclear Energy segments totaling $89.4 million, $13.4 million and $34.1 million, respectively.

Consolidated operating income increased $33.3 million to $239.3 million in the year ended December 31, 2016 compared to $205.9 million for the corresponding period of 2015. Operating income in the Nuclear Energy segment increased $36.8 million due to increased revenue related to our Canadian nuclear service and equipment businesses and the reversal of a $16.1 million loss contingency that resulted from a favorable ruling in a lawsuit involving commercial nuclear contracts. We also experienced improvements in our Nuclear Operations and Other segments of $11.1 million and $7.6 million, respectively. These increases were offset by lower operating income in our Technical Services segment of $1.6 million, an increase in unallocated corporate expenses of $0.6 million and the recording of a $30.0 million charge related to the mPower Framework Agreement. During the year ended December 31, 2015, we recorded income of $65.7 million related to litigation proceeds, which was partially offset by special charges for restructuring activities totaling $16.6 million and costs to spin-off our former Power Generation business totaling $26.0 million. Operating income also includes actuarial gains and losses ("MTM charges") related to our pension and postretirement plans, which reflected non-cash (losses) of $(21.5) million and $(54.7) million in 2016 and 2015, respectively.

Year Ended December 31, 2015 vs. 2014

Consolidated revenues decreased 2.4%, or $35.1 million, to $1,415.5 million in the year ended December 31, 2015 compared to $1,450.6 million for the corresponding period of 2014 due primarily to a $46.4 million cumulative effect impact of a contract change order that was recorded by our Nuclear Operations segment during the year ended December 31, 2014.

Table of Contents

Consolidated operating income increased $180.8 million to $205.9 million in the year ended December 31, 2015 compared to $25.1 million for the corresponding period of 2014. Operating income includes MTM charges related to our pension and postretirement plans, which reflected non-cash (losses) of $(54.7) million and $(141.1) million in 2015 and 2014, respectively. Operating income for the years ended December 31, 2015 and 2014 includes special charges for restructuring activities totaling $16.6 million and $20.9 million, respectively. In addition, operating income for the years ended December 31, 2015 and 2014 also includes costs to spin-off our former Power Generation business totaling $26.0 million and $0.2 million, respectively. Operating income for the year ended December 31, 2015 includes income related to litigation proceeds of $65.7 million. Operating income in our Nuclear Energy segment increased $24.9 million, primarily attributable to a $16.1 million loss resulting from an adverse jury verdict in the prior year. Operating income in our Other segment increased by $55.0 million due to slowing the pace of development related to the mPower program. These increases were partially offset by decreased operating income in our Nuclear Operations and Technical Services segments, which declined $13.1 million and $17.1 million, respectively.

Year Ended December 31, 2016 vs. 2015

Revenues increased by 7.6%, or $89.4 million, to $1,269.3 million in the year ended December 31, 2016 compared to $1,179.9 million for the corresponding period of 2015. This increase was attributable to increased activity in the manufacturing of nuclear components for U.S. Government programs, as well as our naval nuclear fuel and downblending operations.

Operating income increased $11.1 million to $268.5 million in the year ended December 31, 2016 compared to $257.4 million for the corresponding period of 2015. The operating income associated with the increases in revenue noted above was partially offset by an increase in overhead and selling, general and administrative expenses. We also experienced a benefit of $3.0 million from the settlement of a property-related insurance claim during the year ended December 31, 2015.

Year Ended December 31, 2015 vs. 2014

Revenues decreased by 3.4%, or $41.1 million, to $1,179.9 million in the year ended December 31, 2015 compared to $1,221.0 million for the corresponding period of 2014. This decrease in revenues is primarily attributable to a $46.4 million cumulative effect impact of a contract change order that was recorded during the year ended December 31, 2014. This change order continued to benefit segment revenue during 2015 by $17.3 million. Volumes associated with the manufacturing of nuclear components for U.S. Government businesses were higher in 2015 when compared to 2014.

Operating income decreased $13.1 million to $257.4 million in the year ended December 31, 2015 compared to $270.5 million in the corresponding period of 2014, primarily attributable to the change order discussed above that had a $20.6 million favorable impact on operating income in the prior year and continued to benefit 2015 by $9.6 million. Contract improvements in the prior year associated with our naval nuclear fuel and downblending operations resulted in an additional decline in operating income, which was partially offset by a $3.0 million benefit from the settlement of a property-related insurance claim during the year ended December 31, 2015.

Year Ended December 31, 2016 vs. 2015

Revenues increased by 16.0%, or $13.4 million, to $97.2 million in the year ended December 31, 2016 compared to $83.8 million for the corresponding period of 2015. This increase was primarily attributable to higher activity at our Naval Reactor decommissioning and decontamination project.

Operating income decreased $1.6 million to $16.5 million in the year ended December 31, 2016 compared to $18.1 million for the corresponding period of 2015. This was primarily attributable to higher selling, general and administrative expenses of $2.5 million related to an increase in business development activities caused by the timing of bid and proposal activities, as well as expenses of $0.9 million associated with overhead reduction initiatives. These decreases were partially offset by the operating income impact of the revenue increase noted above as well as an increase in equity income of investees of $1.7 million.

Year Ended December 31, 2015 vs. 2014

Revenues totaled $83.8 million and were relatively unchanged when compared to $84.8 million for the prior year. This was primarily attributable to a decrease in specialty manufacturing associated with the termination of our work scope for the American Centrifuge Program that occurred in 2014, which was offset primarily by higher volume at our Naval Reactor decommissioning and decontamination project.

Operating income decreased $17.1 million to $18.1 million in the year ended December 31, 2015 compared to $35.2 million for the corresponding period of 2014. This decrease was primarily attributable to the loss of the Pantex and Y-12 contracts in 2014, which resulted in a decrease in operating income of $21.6 million when compared to the prior year. In addition, the termination of our work scope for the American Centrifuge Program contributed $4.1 million to the decline in operating income. These declines were partially offset by improved fee performance at several of our other sites as well as favorable billing rate adjustments compared to the prior year.

Year Ended December 31, 2016 vs. 2015

Revenues increased by 22.0%, or $34.1 million, to $189.2 million in the year ended December 31, 2016 compared to $155.0 million for the corresponding period of 2015. This increase is attributable, in part, to our services business in Canada, which experienced a higher volume of outage projects, resulting in an increase in revenue of $24.7 million compared to the same period of the prior year. In addition, revenue in our nuclear equipment business increased $22.3 million, primarily due to steam generator design and manufacturing work associated with major life extension and refurbishment projects for the Canadian nuclear industry, as well as the China steam generator project. These increases were partially offset by a decline in service projects in the U.S. as well as the $5.0 million unfavorable impact of the translation of our Canadian dollar denominated contracts into U.S. dollars when compared to the year ended December 31, 2015.

Operating income increased $36.8 million to $38.5 million in the year ended December 31, 2016 compared to $1.7 million for the corresponding period of 2015. The increase in revenue associated with our Canadian nuclear service and equipment businesses noted above combined to increase operating income by $16.0 million. Lower selling, general and administrative expenses resulted in additional operating income improvements of $2.2 million when compared to the year ended December 31, 2015. Also included in operating income was $16.1 million related to the reversal of a loss contingency that resulted from a favorable ruling in a lawsuit involving commercial nuclear contracts.

Year Ended December 31, 2015 vs. 2014

Revenues of $155.0 million were relatively unchanged when compared to the prior year. The translation of our Canadian Dollar denominated contracts into U.S. Dollars had a $12.7 million negative impact on revenue when compared to the prior year. The disposal of our Nuclear Projects business in the second quarter of 2014 resulted in a decline in revenue of $7.3

Table of Contents

million. These decreases were offset by an increase of $9.7 million attributable to our nuclear services business in Canada as well as increased activity in our nuclear equipment business of $8.7 million, which was driven largely by production work on a new steam generator manufacturing project announced in the third quarter of 2015.

Operating income increased $24.9 million to income of $1.7 million in the year ended December 31, 2015 compared to a loss of $23.2 million in the corresponding period of 2014, primarily attributable to a $16.1 million loss recognition resulting from an adverse jury verdict in a lawsuit involving commercial nuclear contracts that occurred during the year ended December 31, 2014. Nuclear services and equipment operating income increased by $6.8 million due to the increased revenue noted above and lower fixed cost resulting from the margin improvement initiatives that began in 2014. Selling, general and administrative expenses also decreased by $2.2 million compared to the same period in 2014 primarily due to margin improvement initiatives.

Year Ended December 31, 2016 vs. 2015

Operating income increased $7.6 million to a loss of $6.4 million in the year ended December 31, 2016 compared to a loss of $13.9 million for the corresponding period of 2015, due to the slowing of the pace of development related to our previously announced plans to restructure the mPower program. Research and development activities decreased $5.2 million and selling, general and administrative expenses also decreased $2.3 million compared to the year ended December 31, 2015.

Year Ended December 31, 2015 vs. 2014

Operating income increased $55.0 million to a loss of $13.9 million in the year ended December 31, 2015 compared to a loss of $68.9 million for the corresponding period of 2014, due to the slowing of the pace of development related to our previously announced plans to restructure the mPower program. Research and development activities related to the development of the BWXT mPower™ reactor decreased $71.2 million, which was partially offset by a $27.8 million decline in reimbursements under a Cooperative Agreement with the DOE under its Small Modular Reactor Licensing Technical Support Program. At this time, the latest extension to the Cooperative Agreement has expired and the DOE funding has been suspended. Selling, general and administrative expenses also decreased $10.7 million compared to the prior year primarily due to the restructuring of our mPower program to focus on technology development.

Unallocated Corporate

Unallocated corporate expenses increased $0.6 million to $26.4 million in the year ended December 31, 2016 compared to $25.7 million for the corresponding period of 2015. Unallocated corporate expenses for the year ended December 31, 2016 include $3.5 million associated with an executive reorganization, which resulted in the acceleration of previously granted equity awards and other expenses. In addition, we also incurred $1.6 million of costs associated with the acquisition of NEC, as well as higher levels of incentive compensation when compared to the year ended December 31, 2015. These additional expenses were more than offset by lower selling, general and administrative expenses resulting from the spin-off, which has allowed the Company to significantly reduce costs that were previously incurred to support a larger organization.

Unallocated corporate expenses of $25.7 million were largely unchanged for the year ended December 31, 2015, as compared to the corresponding period in 2014. Unallocated corporate expenses for the year ended December 31, 2015 include certain expenses that were incurred to manage and provide corporate support of a larger consolidated group prior to the spin-off of our former Power Generation business. General corporate overhead expenses that are not specifically identifiable with our former Power Generation business are reflected as part of continuing operations for the historical financial statements.

mPower Framework Agreement

On March 2, 2016, as a result of entering into the Framework Agreement, we have deconsolidated GmP from our financial statements as of the date of the Framework Agreement. We recorded a gain of approximately $13.6 million during the year ended December 31, 2016 related to the deconsolidation of GmP as a component of other – net in our consolidated

Table of Contents

statement of income. In addition, we also recorded a $30.0 million loss contingency pursuant to the terms of the Framework Agreement.

For additional information on the Framework Agreement, see Note 11 to our consolidated financial statements.

Income Related to Litigation Proceeds

In September 2015, we received a $94.8 million payment, inclusive of pre- and post-judgment interest totaling $29.1 million, in connection with a legal judgment. Operating income includes income related to these litigation proceeds of $65.7 million for the year ended December 31, 2015. See Note 11 to our consolidated financial statements included in this report for further information related to this legal judgment.

Special Charges for Restructuring Activities

Special charges for restructuring activities decreased $4.3 million to $16.6 million in the year ended December 31, 2015, as compared to $20.9 million in 2014, due to increased charges associated with our restructuring of our mPower program, offset by decreased charges related to our margin improvement program. All restructuring activities had reached substantial completion as of December 31, 2015, and we do not anticipate significant expenditures related to any of these initiatives.

Cost to Spin-off Power Generation Business

We incurred $26.0 million of costs related to the spin-off of our former Power Generation business in 2015. These charges consisted of $21.4 million in retention and severance-related costs, $2.4 million of facility costs and $2.2 million of professional services and other charges. We do not anticipate any further charges associated with the spin-off. See Note 3 to our consolidated financial statements included in this report for further information related to the spin-off.

Mark to Market Adjustment

We immediately recognize actuarial gains (losses) for our pension and postretirement benefit plans into earnings as a component of net periodic benefit cost. The effect of this adjustment on operating income was $(21.5) million in 2016, as compared to $(54.7) million in 2015. The mark to market loss recorded during the year ended December 31, 2016 was primarily due to a change in the weighted-average discount rate for our pension and postretirement benefit plans as well as the difference between actual and estimated participant data and demographic factors, including items such as retirement age and rates of termination, retirement and mortality.

The effect of the mark to market adjustment on operating income was $(54.7) million in 2015, as compared to $(141.1) million in 2014, which included a $70.9 million loss recognized in 2014 on the adoption of a new mortality assumption and a decline in discount rates. The mark to market loss recorded during the year ended December 31, 2015 was primarily related to the difference between the actual return on plan assets and the expected return.

Other Income Statement Items

Other – net increased $30.8 million to a gain of $25.7 million in the year ended December 31, 2016, as compared to a loss of $5.0 million for the corresponding period of 2015. During the year ended December 31, 2016, we recorded a gain of $13.6 million related to the deconsolidation of GmP. In addition, we were released from substantially all outstanding performance guarantees for various projects executed by our former Power Generation business prior to the spin-off, which resulted in a gain of $9.3 million. We also recognized a gain associated with a fair market value adjustment of our investment in Centrus of $1.6 million in the year ended December 31, 2016 compared to a $3.9 million loss on our investment in the year ended December 31, 2015 which included an other than temporary impairment of $2.1 million.

Other – net decreased $18.9 million to a loss of $5.0 million in the year ended December 31, 2015, as compared to a gain of $13.9 million for the corresponding period of 2014, primarily due to the receipt and related fair market value adjustment of Centrus shares and notes received on USEC’s emergence from bankruptcy in the year ended December 31, 2014 totaling $14.2 million. We subsequently recognized a $3.9 million loss on our investment in Centrus in the year ended December 31, 2015.

Net (Income) Loss Attributable to Noncontrolling Interest

Net (income) loss attributable to noncontrolling interest was largely unchanged in the year ended December 31, 2016 compared to 2015.

Table of Contents

Net (income) loss attributable to noncontrolling interest decreased $7.9 million in the year ended December 31, 2015 compared to 2014, primarily attributable to a decline in recognition of our partner’s share of losses incurred in connection with BWXT mPower™ reactor development efforts as a result of the restructuring of the mPower program.

Provision for Income Taxes



	Year Ended December 31,
	2016		2015		2014
Income from Continuing Operations before Provision for Income Taxes and Noncontrolling Interest	$	257,268	$	221,065	$	32,135
Provision for Income Taxes	73,656		80,416		1,691
Effective Tax Rate	28.6%		36.4%		5.3%

For the year ended December 31, 2016, our provision for income taxes decreased $6.8 million to $73.7 million, while income before provision for income taxes increased $36.2 million to $257.3 million. Our effective tax rate was approximately 28.6% for 2016, as compared to 36.4% for 2015. Our effective tax rate for 2016 was less than our statutory rate primarily due to the $13.6 million non-taxable gain recognized related to the deconsolidation of GmP, $2.4 million of additional tax benefits related to employee share-based payments due to our early adoption of the FASB update to the Topic Compensation – Stock Compensation (for additional information, see Note 1 to our consolidated financial statements included in this report), and a $7.5 million benefit for the change in our assertion regarding the undistributed earnings of our foreign operations. Of the $7.5 million benefit associated with the change in our assertion regarding the undistributed earnings of our foreign operations, approximately $3.9 million related to the foreign rate differential on current year undistributed earnings and approximately $3.6 million related to the reversal of deferred tax liabilities recorded for previously accrued taxes.

For the year ended December 31, 2015, our provision for income taxes increased $78.7 million to $80.4 million, while income before provision for income taxes increased $188.9 million to $221.1 million. Our effective tax rate was approximately 36.4% for 2015, as compared to 5.3% for 2014. Our effective tax rate for 2015 exceeded our statutory rate primarily due to the change in our tax footprint associated with the spin-off of our former Power Generation business, resulting in revaluations of deferred tax assets and liabilities as well as the need to recognize tax provision on our global earnings at our U.S. federal rate due to the likely repatriation of future foreign earnings. In addition, our effective tax rate is higher due to the increase in the valuation allowance related to fair market value adjustments on our Centrus investment and the loss of certain capital loss carry back opportunities. These amounts were partially offset due to the release of uncertain tax positions and adjustments related to the filing of our 2014 U.S. tax return.

We are subject to U.S. federal tax at a statutory rate of 35% on our U.S. operations plus the applicable state income taxes on our profitable U.S. subsidiaries. Our non-U.S. earnings are predominantly generated in Canada and are subject to tax at a local statutory rate of approximately 25%.

See Note 6 to our consolidated financial statements included in this report for further information on income taxes including further discussion on the change to our assertion regarding the undistributed earnings of our foreign operations.

EFFECTS OF INFLATION AND CHANGING PRICES

Our financial statements are prepared in accordance with generally accepted accounting principles in the U.S., using historical U.S. dollar accounting ("historical cost"). Statements based on historical cost, however, do not adequately reflect the cumulative effect of increasing costs and changes in the purchasing power of the U.S. dollar, especially during times of significant and continued inflation.

In order to minimize the negative impact of inflation on our operations, we attempt to cover the increased cost of anticipated changes in labor, material and service costs, either through an estimate of those changes, which we reflect in the original price, or through price escalation clauses in our contracts. However, there can be no assurance we will be able to cover all changes in cost using this strategy.

LIQUIDITY AND CAPITAL RESOURCES

Our overall liquidity position, which we generally define as our unrestricted cash and investments plus amounts available for borrowings under our credit facility, remained strong in 2016. Our liquidity position at December 31, 2016 decreased by approximately $87.8 million to $394.3 million from $482.1 million at December 31, 2015, mainly due to the repurchase of

Table of Contents

common shares and the acquisition of NEC, partially offset by the cash generated from earnings. We experienced net cash generated from operations in each of the years ended December 31, 2016, 2015 and 2014. Typically, the fourth quarter has been the period of highest cash flows from operating activities because of the timing of payments received from the U.S. Government on accounts receivable retainages and cash dividends received from our joint ventures.

Credit Facility

On September 2, 2016, we entered into an amendment (the "Amendment") to our Credit Agreement dated May 11, 2015 with Bank of America, N.A., as administrative agent, and certain lenders and letter of credit issuers party thereto (collectively, the "Amended Credit Agreement"). Prior to the Amendment, our Credit Agreement provided for a five-year, senior secured revolving credit facility in an aggregate amount of up to $400 million, the full amount of which is available for the issuance of letters of credit, and a senior secured term loan facility of $300 million, which was drawn on June 30, 2015. The Amendment added a new U.S. dollar term loan facility in an aggregate principal amount of up to $112.5 million, which was drawn on September 16, 2016, and a new Canadian dollar term loan facility in an aggregate principal amount of up to the equivalent of $137.5 million U.S. dollars, which was drawn on December 12, 2016 (collectively, the "Incremental Term Loans"). All obligations under the Amended Credit Agreement are scheduled to mature on June 30, 2020. The proceeds of loans under the Amended Credit Agreement are available for working capital needs and other general corporate purposes.

The Amended Credit Agreement includes provisions for additional financial institutions to become lenders, or for any existing lender to increase its commitment thereunder, subject to an aggregate maximum of $250 million for all additional term loans, revolving credit borrowings and letter of credit commitments.

The Amended Credit Agreement is (1) guaranteed by substantially all of our wholly owned domestic subsidiaries, excluding our captive insurance subsidiary, and (2) secured by first-priority liens on certain assets owned by us and the guarantors (other than the our subsidiaries comprising our Nuclear Operations and Technical Services segments).

The Amended Credit Agreement requires interest payments on revolving loans on a periodic basis until maturity. We began making quarterly amortization payments on the $300 million term loan in an amount equal to 1.25% of the aggregate principal amount in the first quarter of 2016. We began making quarterly amortization payments on the U.S. dollar term loan facility in an amount equal to 1.25% of the aggregate principal amount in the fourth quarter of 2016. We will be required to make quarterly amortization payments on the Canadian dollar term loan facility in an amount equal to 1.25% of the aggregate principal amount beginning in the first quarter of 2017. We may prepay all loans under the Amended Credit Agreement at any time without premium or penalty (other than customary Eurocurrency Rate breakage costs), subject to notice requirements.

The Amended Credit Agreement includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted leverage ratio is 3.00 to 1.00, which may be increased to 3.25 to 1.00 for up to four consecutive fiscal quarters after a material acquisition. The minimum consolidated interest coverage ratio is 4.00 to 1.00. In addition, the Amended Credit Agreement contains various restrictive covenants, including with respect to debt, liens, investments, mergers, acquisitions, dividends, equity repurchases and asset sales. At December 31, 2016, we were in compliance with all covenants set forth in the Amended Credit Agreement.

Outstanding loans under the Amended Credit Agreement bear interest at our option at either the Eurocurrency Rate plus a margin ranging from 1.25% to 1.75% per year or the base rate (the highest of the Federal Funds rate plus 0.50%, the one-month Eurocurrency Rate plus 1.0%, or the administrative agent’s prime rate) plus a margin ranging from 0.25% to 0.75% per year. We are charged a commitment fee on the unused portions of the revolving credit facility, and that fee varies between 0.15% and 0.25% per year. Additionally, we are charged a letter of credit fee of between 1.25% and 1.75% per year with respect to the amount of each financial letter of credit issued under the Amended Credit Agreement, and a letter of credit fee of between 0.75% and 1.05% per year is charged with respect to the amount of each performance letter of credit issued under the Amended Credit Agreement. The applicable margin for loans, the commitment fee and the letter of credit fees set forth above will vary quarterly based on our leverage ratio. Upon the closing of the Credit Agreement and the subsequent Amendment, we paid certain upfront fees to the lenders thereunder, and paid arrangement and other fees to the arrangers and agents of the Amended Credit Agreement. At December 31, 2016, borrowings outstanding totaled $531.0 million and $0.0 million under our term loans and revolving line of credit, respectively, and letters of credit issued under the Amended Credit Agreement totaled $154.9 million. As a result, we had $245.1 million available for borrowings or to meet letter of credit requirements as of December 31, 2016, excluding the additional $250 million available to us for term loan, revolving credit borrowings and letter of credit commitments. As of December 31, 2016, the weighted-average interest rate on outstanding borrowings under our Amended Credit Agreement was 2.08%.

Table of Contents

Based on the current credit ratings of the Amended Credit Agreement, the applicable margin for Eurocurrency Rate loans is 1.375% for the term loan facility drawn June 30, 2015 and 1.375% for the Incremental Term Loans. The letter of credit fee for financial letters of credit is 1.375%, and the letter of credit fee for performance letters of credit is 0.825%. The commitment fee for unused portions of the revolving credit facility is 0.175%. The applicable interest rate at December 31, 2016 was 4.125% per year for the revolving credit facility. The Amended Credit Agreement does not have a floor for the base rate or the Eurocurrency Rate.

The Amended Credit Agreement generally includes customary events of default for a secured credit facility, some of which allow for an opportunity to cure. If an event of default relating to bankruptcy or other insolvency events occurs under the Amended Credit Agreement, all obligations under the Amended Credit Agreement will immediately become due and payable. If any other event of default exists under the Amended Credit Agreement, the lenders will be permitted to accelerate the maturity of the obligations outstanding under the Amended Credit Agreement. If any event of default occurs under the Amended Credit Agreement, the lenders will be permitted to terminate their commitments thereunder and exercise other rights and remedies, including the commencement of foreclosure or other actions against the collateral.

If any default occurs under the Amended Credit Agreement, or if we are unable to make any of the representations and warranties in the Amended Credit Agreement, we will be unable to borrow funds or have letters of credit issued under the Amended Credit Agreement.

Other Arrangements

We have posted surety bonds to support contractual obligations to customers relating to certain projects and legal matters. We utilize bonding facilities to support such obligations, but the issuance of bonds under those facilities is typically at the surety’s discretion. Although there can be no assurance that we will maintain our surety bonding capacity, we believe our current capacity is adequate to support our existing project requirements for the next twelve months. In addition, these bonds generally indemnify customers should we fail to perform our obligations under the applicable contracts. We, and certain of our subsidiaries, have jointly executed general agreements of indemnity in favor of surety underwriters relating to surety bonds those underwriters issue in support of some of our contracting activity. As of December 31, 2016, bonds issued and outstanding under these arrangements in support of contracts totaled approximately $19.7 million.

OTHER

Cash, Cash Equivalents, Restricted Cash and Investments

In the aggregate, our cash and cash equivalents, restricted cash and cash equivalents and investments decreased by approximately $24.3 million to $158.1 million at December 31, 2016 from $182.4 million at December 31, 2015, primarily due to the items discussed below. Our domestic and foreign cash and cash equivalents, restricted cash and cash equivalents and investments as of December 31, 2016 and 2015 were as follows:



	December 31,
	2016		2015
	(In thousands)
Domestic	$	92,680	$	158,679
Foreign	65,449		23,733
Total	$	158,129	$	182,412

Our working capital decreased by $39.8 million to $253.7 million at December 31, 2016 from $293.5 million at December 31, 2015, attributable to the changes in cash and borrowings under our credit facility discussed below, which were partially offset by changes in net contracts in progress and advance billings due to the timing of project cash flows.

Our net cash provided by operating activities decreased by $95.3 million to $239.9 million in the year ended December 31, 2016, compared to cash provided by operating activities of $335.2 million in the year ended December 31, 2015. This decrease was largely attributable to changes in net contracts in progress and advance billings discussed above.

Our net cash used in investing activities increased by $107.8 million to $179.7 million in the year ended December 31, 2016, compared to cash used in investing activities of $71.9 million in the year ended December 31, 2015. The higher cash used in investing activities in 2016 was primarily attributable to the acquisition of NEC.

Table of Contents

Our net cash used in financing activities decreased by $325.5 million to $88.9 million in the year ended December 31, 2016, compared to cash used in financing activities of $414.4 million in the year ended December 31, 2015. This decrease in net cash used in financing activities was primarily attributable to cash divested in connection with the spin-off of our former Power Generation business in the prior year. In addition, we repurchased $293.0 million common shares during 2016 and borrowed a net $233.6 million under our credit facility.

At December 31, 2016, we had restricted cash and cash equivalents totaling $9.0 million, $2.9 million of which was held for future decommissioning of facilities (which is included in other assets on our consolidated balance sheets) and $6.1 million of which was held to meet reinsurance reserve requirements of our captive insurer.

At December 31, 2016, we had short-term and long-term investments with a fair value of $23.5 million. Our investment portfolio consists primarily of investments in corporate bonds, equities and highly liquid money market instruments. Our investments are carried at fair value and are either classified as trading, with unrealized gains and losses reported in earnings, or as available-for-sale, with unrealized gains and losses, net of tax, being reported as a component of other comprehensive income.

Based on our liquidity position, we believe we have sufficient cash and letter of credit and borrowing capacity to fund our operating requirements for at least the next twelve months.

CONTRACTUAL OBLIGATIONS

Our cash requirements as of December 31, 2016 under current contractual obligations were as follows:

We expect cash requirements totaling approximately $24.5 million for contributions to our pension plans in 2017. In addition, we anticipate cash requirements totaling approximately $1.5 million for contributions to our other postretirement benefit plans in 2017.

Our contingent commitments under letters of credit, bank guarantees and surety bonds currently outstanding expire as follows:

Item 7A.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk from changes in interest rates relates primarily to our cash equivalents and our investment portfolio, which primarily consists of investments in highly liquid money market instruments denominated in U.S. dollars. Additionally, we hold corporate bonds, equities, mutual funds and commercial paper. We are averse to principal loss and seek to ensure the safety and preservation of our invested funds by limiting default risk, market risk and reinvestment risk. Our investments are primarily classified as available-for-sale.

We have exposure to changes in interest rates on the Amended Credit Agreement (see Item 7 – "Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources"). At December 31, 2016, we had $531.0 million in outstanding borrowings under this facility, which has a capacity of $931.0 million. We have no material future earnings or cash flow exposures from changes in interest rates on our other long-term debt obligations.

We have operations in foreign locations, and, as a result, our financial results could be significantly affected by factors such as changes in foreign currency exchange ("FX") rates or weak economic conditions in those foreign markets. In order to

manage the risks associated with FX rate fluctuations, we attempt to hedge those risks with FX derivative instruments. Historically, we have hedged those risks with FX forward contracts. We do not enter into speculative derivative positions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2016

NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

We have presented the consolidated financial statements of BWX Technologies, Inc. ("BWXT") in U.S. dollars in accordance with accounting principles generally accepted in the United States ("GAAP").

We use the equity method to account for investments in entities that we do not control, but over which we have the ability to exercise significant influence. We generally refer to these entities as "joint ventures." We have eliminated all intercompany transactions and accounts. We have reclassified certain amounts previously reported to conform to the presentation at December 31, 2016 and for the year ended December 31, 2016. We present the notes to our consolidated financial statements on the basis of continuing operations, unless otherwise stated.

Unless the context otherwise indicates, "we," "us" and "our" mean BWXT and its consolidated subsidiaries.

Spin-off

On June 30, 2015, we completed the spin-off of our former Power Generation business (the "spin-off") into an independent, publicly traded company named Babcock & Wilcox Enterprises, Inc. ("BWE"). The separation was effected through a pro rata distribution of 100% of BWE's common stock to BWXT's stockholders. The distribution of BWE common stock consisted of one share of BWE common stock for every two shares of BWXT common stock to holders of our common stock on the record date of June 18, 2015. Cash was paid in lieu of any fractional shares of BWE common stock. Following the spin-off, BWXT did not retain any ownership interest in BWE. Prior to June 30, 2015, we completed an internal restructuring that reorganized the subsidiaries involved in our former Power Generation business and established BWE as the direct or indirect parent company of those subsidiaries. Concurrent with the spin-off, The Babcock & Wilcox Company was renamed BWX Technologies, Inc. The results of operations of our former Power Generation business are presented as discontinued operations on the condensed consolidated statements of income. See Note 3 for further information regarding the spin-off of BWE.

Reportable Segments

We operate in three reportable segments: Nuclear Operations, Technical Services and Nuclear Energy. Our former Power Generation business is now reported as discontinued operations. Prior to 2015, our mPower business was a separate reportable segment and is now included in our "Other" category. Our reportable segments are further described as follows:

•

Our Nuclear Operations segment engineers, designs and manufactures naval nuclear reactors for the U.S. Department of Energy ("DOE")/National Nuclear Security Administration's ("NNSA") Naval Nuclear Propulsion Program, which in turn supplies them to the U.S. Navy for use in submarines and aircraft carriers. Through this segment, we own and operate manufacturing facilities located in Lynchburg, Virginia; Mount Vernon, Indiana; Euclid, Ohio; Barberton, Ohio; and Erwin, Tennessee. The Barberton and Mount Vernon locations specialize in the design and manufacture of heavy components inclusive of development and fabrication activities for submarine missile launch tubes. The Euclid facility fabricates electro-mechanical equipment for the U.S. Government, and performs design, manufacturing, inspection, assembly and testing activities. The Lynchburg operations fabricate fuel-bearing precision components that range in weight from a few grams to hundreds of tons. In-house capabilities also include wet chemistry uranium processing, advanced heat treatment to optimize component material properties and a controlled, clean-room environment with the capacity to assemble railcar-size components. Fuel for the naval nuclear reactors is provided by Nuclear Fuel Services, Inc. ("NFS"), one of our wholly owned subsidiaries. Located in Erwin, Tennessee, NFS also converts Cold War-era government stockpiles of highly enriched uranium into material suitable for further processing into commercial nuclear reactor fuel.

•

Our Technical Services segment provides various services to the U.S. Government, including uranium processing, environmental site restoration services and management and operating services for various U.S. Government-owned facilities. These services are provided to the DOE including the NNSA, the Office of Nuclear Energy, the Office of Science, and the Office of Environmental Management; the Department of Defense and NASA. Through this segment, we deliver products and management solutions to nuclear operations and high-consequence manufacturing facilities. A significant portion of this segment's operations are conducted through joint ventures.

•

Our Nuclear Energy segment supplies commercial nuclear steam generators and components to nuclear utility customers. BWXT has supplied the nuclear industry with more than 1,300 large, heavy components worldwide. This segment is the only heavy nuclear component manufacturer in North America that is N-Stamp certified by the American Society of Mechanical Engineers. Our Nuclear Energy segment fabricates pressure vessels, reactors, steam generators, heat exchangers and other auxiliary equipment. This segment also provides specialized engineering services that include structural component design, 3-D thermal-hydraulic engineering analysis, weld and robotic process development and metallurgy and materials engineering. In addition, this segment offers services for nuclear steam generators and balance of plant equipment, as well as nondestructive examination and tooling/repair solutions for other plant systems and components. This segment also offers engineering and licensing services for new nuclear plant designs.

For financial information about our segments, see Note 17 to our consolidated financial statements.

Deconsolidation of Generation mPower LLC

On March 2, 2016, we entered into a framework agreement with Bechtel Power Corporation ("Bechtel"), BWXT Modular Reactors, LLC and BDC NexGen Power, LLC for the potential restructuring and restart of our mPower small modular reactor program (the "Framework Agreement"). As a result of entering into the Framework Agreement, we have deconsolidated Generation mPower LLC ("GmP") from our financial statements as of the date of the Framework Agreement. We recorded a gain of approximately $13.6 million during the year ended December 31, 2016 related to the deconsolidation of GmP as a component of other – net in our consolidation statement of income. In addition, we also recorded a $30.0 million loss contingency pursuant to the terms of the Framework Agreement.

For additional information on the Framework Agreement, see Note 11 to our consolidated financial statements.

Use of Estimates

We use estimates and assumptions to prepare our financial statements in conformity with GAAP. Some of our more significant estimates include our estimate of costs to complete long-term construction contracts, estimates of the fair value of acquired intangible assets, estimates of costs to be incurred to satisfy contractual warranty requirements, and estimates we make in selecting assumptions related to the valuations of our pension and postretirement plans, including the selection of our discount rates, mortality and expected rates of return on our pension plan assets. These estimates and assumptions affect the amounts we report in our financial statements and accompanying notes. Our actual results could differ from these estimates. Variances could result in a material effect on our financial condition and results of operations in future periods.

Earnings Per Share

We have computed earnings per common share on the basis of the weighted average number of common shares, and, where dilutive, common share equivalents, outstanding during the indicated periods. We issue a number of forms of stock-based compensation periodically, including incentive and non-qualified stock options, restricted stock, restricted stock units and performance shares and performance units, subject to satisfaction of specific performance goals. We include the shares applicable to these plans in dilutive earnings per share when related performance criteria have been met.

Investments

Our investment portfolio consists primarily of highly liquid money market instruments, bonds and equities. Our investments are carried at fair value and are either classified as trading, with unrealized gains and losses reported in earnings, or

Table of Contents

as available-for-sale, with the unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income. We classify investments available for current operations in the consolidated balance sheets as current assets, while we classify investments held for long-term purposes as non-current assets. We adjust the amortized cost of debt securities for amortization of premiums and accretion of discounts to maturity. That amortization is included in interest income. We include realized gains and losses on our investments in other – net. The cost of securities sold is based on the specific identification method. We include interest on securities in interest income.

Foreign Currency Translation

We translate assets and liabilities of our foreign operations into U.S. dollars at current exchange rates, and we translate income statement items at average exchange rates for the periods presented. We record adjustments resulting from the translation of foreign currency financial statements as a component of accumulated other comprehensive income. We report foreign currency transaction gains and losses in income. We have included in other – net transaction gains (losses) of $0.4 million, $(1.7) million and $0.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Contracts and Revenue Recognition

We generally recognize contract revenues and related costs on a percentage-of-completion method for individual contracts or combinations of contracts based on work performed, man hours or a cost-to-cost method, as applicable to the product or activity involved. We recognize estimated contract revenue and resulting income based on the measurement of the extent of progress completion as a percentage of the total project. Certain costs may be excluded from the cost-to-cost method of measuring progress, such as significant costs for materials and major third-party subcontractors, if it appears that such exclusion would result in a more meaningful measurement of actual contract progress and resulting periodic allocation of income. We include revenues and related costs so recorded, plus accumulated contract costs that exceed amounts invoiced to customers under the terms of the contracts, in contracts in progress. We include in advance billings on contracts billings that exceed accumulated contract costs and revenues and costs recognized under the percentage-of-completion method. Most long-term contracts contain provisions for progress payments. Our unbilled receivables do not contain an allowance for credit losses as we expect to invoice customers and collect all amounts for unbilled revenues. We review contract price and cost estimates periodically as the work progresses and reflect adjustments proportionate to the percentage-of-completion in income in the period when those estimates are revised. For all contracts, if a current estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full when determined.

For contracts as to which we are unable to estimate the final profitability except to assure that no loss will ultimately be incurred, we recognize equal amounts of revenue and cost until the final results can be estimated more precisely. For these deferred profit recognition contracts, we recognize revenue and cost equally and only recognize gross margin when probable and reasonably estimable, which we generally determine to be when the contract is approximately 70% complete. We treat long-term construction contracts that contain such a level of risk and uncertainty that estimation of the final outcome is impractical, except to assure that no loss will be incurred, as deferred profit recognition contracts.

Our policy is to account for fixed-price contracts under the completed-contract method if we believe that we are unable to reasonably forecast cost to complete at start-up. Under the completed-contract method, income is recognized only when a contract is completed or substantially complete.

Variations from estimated contract performance could result in material adjustments to operating results for any fiscal quarter or year. We include claims for extra work or changes in scope of work to the extent of costs incurred in contract revenues when we believe collection is probable. In the year ended December 31, 2014, we executed a change order in our Nuclear Operations segment that increased the value of existing contracts by $70.5 million. We recognized $46.4 million of revenue for the cumulative effect of this contract change, as well as $25.8 million in cost of operations for the recognition of the associated costs being recovered during 2014. The impact of the executed change order increased diluted earnings per share by $0.12.

Asset Retirement Obligations and Environmental Clean-up Costs

We accrue for future decommissioning of our nuclear facilities that will permit the release of these facilities to unrestricted use at the end of each facility's life, which is a requirement of our licenses from the U.S. Nuclear Regulatory Commission ("NRC") and the CNSC. In accordance with the FASB Topic Asset Retirement and Environmental Obligations, we record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When we initially record such a liability, we capitalize a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of a liability, we will settle the obligation for its recorded amount or incur a gain or loss. This topic

Table of Contents

applies to environmental liabilities associated with assets that we currently operate and are obligated to remove from service. For environmental liabilities associated with assets that we no longer operate, we have accrued amounts based on the estimated costs of clean-up activities for which we are responsible, net of any cost-sharing arrangements. We adjust the estimated costs as further information develops or circumstances change. An exception to this accounting treatment relates to the work we perform for two facilities for which the U.S. Government is obligated to pay substantially all of the decommissioning costs.

Substantially all of our asset retirement obligations relate to the remediation of our nuclear analytical laboratory and the NFS facility in our Nuclear Operations segment as well as the facilities operated by NEC. The following table reflects our asset retirement obligations:

Research and Development

Research and development activities totaled $40.1 million, $38.2 million and $124.3 million in the years ended December 31, 2016, 2015 and 2014, respectively. This includes amounts paid for by our customers of $33.7 million, $27.7 million and $41.7 million, in the years ended December 31, 2016, 2015 and 2014, respectively, and DOE funds provided under the Funding Program of $27.8 million in the year ended December 31, 2014.

During the year ended December 31, 2014, we recognized $5.8 million of non-cash in-kind research and development costs (included above) related to services contributed by our minority partner to GmP, our majority-owned subsidiary formed in 2011 to oversee the program to develop the small modular nuclear power plant based on BWXT mPower™ technology.

Pension Plans and Postretirement Benefits

We sponsor various defined benefit pension and postretirement plans covering certain employees of our U.S. and Canadian subsidiaries. We utilize actuarial valuations to calculate the cost and benefit obligations of our pension and postretirement benefits. The actuarial valuations utilize significant assumptions in the determination of our benefit cost and obligations, including assumptions regarding discount rates, expected returns on plan assets, mortality and health care cost trends. We determine our discount rate based on a yield curve comprised of rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of our pension and postretirement plan obligations. The expected rate of return on plan assets assumption is based on capital market assumptions of the long-term expected returns for the investment mix of assets currently in the portfolio. The expected rate of return on plan assets is determined to be the weighted average of the nominal returns based on the weightings of the classes within the total asset portfolio. Expected health care cost trends represent expected annual rates of change in the cost of health care benefits and are estimated based on analysis of health care cost inflation. For the year ended December 31, 2014, we adjusted the mortality assumption for our domestic plans to reflect mortality improvements identified by the Society of Actuaries, adjusted for BWXT's experience.

Table of Contents

The components of benefit cost related to service cost, interest cost, expected return on plan assets and prior service cost amortization are recorded on a quarterly basis based on actuarial assumptions. In the fourth quarter of each year, or as interim remeasurements are required, we immediately recognize net actuarial gains and losses into earnings as a component of net periodic benefit cost. Recognized net actuarial gains and losses consist primarily of our reported actuarial gains and losses and the difference between the actual return on plan assets and the expected return on plan assets.

We recognize the funded status of each plan as either an asset or a liability in the consolidated balance sheets. The funded status is the difference between the fair value of plan assets and the present value of its benefit obligation, determined on a plan-by-plan basis. Our pension plan assets can include assets that are difficult to value. See Note 8 for a detailed description of our plan assets.

Income Taxes

Income tax expense for federal, foreign, state and local income taxes are calculated on pre-tax income based on current tax law and includes the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. We assess deferred taxes and the adequacy of the valuation allowance on a quarterly basis. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management's evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. We record interest and penalties (net of any applicable tax benefit) related to income taxes as a component of provision for income taxes on our consolidated statements of income.

Inventories

We carry our inventory at the lower of cost or market. At December 31, 2016 and 2015, we had inventories totaling $7.7 million and $7.3 million, respectively, consisting entirely of raw materials and supplies.

Property, Plant and Equipment

We carry our property, plant and equipment at depreciated cost, less any impairment provisions. We depreciate our property, plant and equipment using the straight-line method over estimated economic useful lives of eight to 33 years for buildings and three to 14 years for machinery and equipment. Our depreciation expense was $48.4 million, $55.3 million and $72.1 million for the years ended December 31, 2016, 2015 and 2014, respectively. We expense the costs of maintenance, repairs and renewals that do not materially prolong the useful life of an asset as we incur them.

Investments in Unconsolidated Affiliates

We use the equity method of accounting for affiliates in which we are able to exert significant influence. Currently, substantially all of our material investments in affiliates that are not consolidated are recorded using the equity method. Affiliates in which our investment ownership is less than 20% and where we are unable to exert significant influence are carried at cost.

Goodwill

Goodwill represents the excess of the cost of our acquired businesses over the fair value of the net assets acquired. We perform testing of goodwill for impairment annually. We may elect to perform a qualitative test when we believe that there is sufficient excess fair value over carrying value based on our most recent quantitative assessment, adjusted for relevant events and circumstances that could affect fair value during the current year. If we conclude based on this assessment that it is more likely than not that the reporting unit is not impaired, we do not perform a quantitative impairment test. In all other circumstances, we utilize a two-step quantitative impairment test to identify potential goodwill impairment and measure the amount of any goodwill impairment. The first step of the test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of the impairment loss, if any. The second step compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.

The following summarizes the changes in the carrying amount of goodwill:

Intangible Assets

Intangible assets are recognized at fair value when acquired. Intangible assets with definite lives are amortized to operating expense using the straight-line method over their estimated useful lives and tested for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable. Intangible assets with indefinite lives are not amortized and are subject to annual impairment testing. We may elect to perform a qualitative assessment when testing indefinite lived intangible assets for impairment to determine whether events or circumstances affecting significant inputs related to the most recent quantitative evaluation have occurred, indicating that it is more likely than not that the indefinite lived intangible asset is impaired. Otherwise, we test indefinite lived intangible assets for impairment by quantitatively determining the fair value of the indefinite lived intangible asset and comparing the fair value of the intangible asset to its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, we recognize impairment for the amount of the difference.

Capitalization of Interest Cost

We capitalize interest in accordance with FASB Topic Interest. We incurred total interest of $9.1 million, $10.9 million and $8.9 million in the years ended December 31, 2016, 2015 and 2014, respectively, of which we capitalized $0.7 million, $0.7 million and $1.8 million in the years ended December 31, 2016, 2015 and 2014, respectively.

Cash and Cash Equivalents and Restricted Cash

Our cash equivalents are highly liquid investments with maturities of three months or less when we purchase them.

We record cash and cash equivalents as restricted when we are unable to freely use such cash and cash equivalents for our general operating purposes. At December 31, 2016, we had restricted cash and cash equivalents totaling $9.0 million, $2.9 million of which was held for future decommissioning of facilities (which is included in other assets on our consolidated balance sheets) and $6.1 million of which was held to meet reinsurance reserve requirements of our captive insurer.

Derivative Financial Instruments

Our Canadian operations give rise to exposure to market risks from changes in foreign currency exchange ("FX") rates. We use derivative financial instruments, primarily FX forward contracts, to reduce the impact of changes in FX rates on our operating results. We use these instruments primarily to hedge our exposure associated with revenues or costs on our long-term contracts that are denominated in currencies other than our operating entities' functional currencies. We do not hold or issue derivative financial instruments for trading or other speculative purposes.

We enter into derivative financial instruments primarily as hedges of certain firm purchase and sale commitments denominated in foreign currencies. We record these contracts at fair value on our consolidated balance sheets and defer the related gains and losses in stockholders' equity as a component of accumulated other comprehensive income until the hedged item is recognized in earnings. Any ineffective portion of a derivative's change in fair value and any portion excluded from the assessment of effectiveness is immediately recognized in other – net on our consolidated statements of income. The gain or loss on a derivative instrument not designated as a hedging instrument is also immediately recognized in earnings. Gains and losses on derivative financial instruments that require immediate recognition are included as a component of other – net in our consolidated statements of income.

Self-Insurance

We have a wholly owned insurance subsidiary that provides employer's liability, general and automotive liability and workers' compensation insurance and, from time to time, builder's risk insurance (within certain limits) to our companies. We may also, in the future, have this insurance subsidiary accept other risks that we cannot or do not wish to transfer to outside insurance companies. Included in other liabilities on our consolidated balance sheets are reserves for self-insurance totaling $7.2 million and $6.9 million at December 31, 2016 and 2015, respectively.

Table of Contents

Loss Contingencies

We estimate liabilities for loss contingencies when it is probable that a liability has been incurred and the amount of loss is reasonably estimable. We provide disclosure when there is a reasonable possibility that the ultimate loss will exceed the recorded provision or if such probable loss is not reasonably estimable. We are currently involved in some significant litigation, as discussed in Note 11. Our losses are typically resolved over long periods of time and are often difficult to assess and estimate due to, among other reasons, the possibility of multiple actions by third parties; the attribution of damages, if any, among multiple defendants; plaintiffs, in most cases involving personal injury claims, do not specify the amount of damages claimed; the discovery process may take multiple years to complete; during the litigation process, it is common to have multiple complex unresolved procedural and substantive issues; the potential availability of insurance and indemnity coverages; the wide-ranging outcomes reached in similar cases, including the variety of damages awarded; the likelihood of settlements for de minimus amounts prior to trial; the likelihood of success at trial; and the likelihood of success on appeal. Consequently, it is possible future earnings could be affected by changes in our assessments of the probability that a loss has been incurred in a material pending litigation against us and/or changes in our estimates related to such matters.

Stock-Based Compensation

We expense stock-based compensation in accordance with FASB Topic Compensation – Stock Compensation. Under this topic, the fair value of equity-classified awards, such as restricted stock, performance shares and stock options, is determined on the date of grant and is not remeasured. The fair value of liability-classified awards, such as cash-settled stock appreciation rights, restricted stock units and performance units, is determined on the date of grant and is remeasured at the end of each reporting period through the date of settlement. Grant date fair values for restricted stock, restricted stock units, performance shares and performance units are determined using the closing price of our common stock on the date of grant. Grant date fair values for stock options and stock appreciation rights are determined using a Black-Scholes option-pricing model ("Black-Scholes"). The determination of the fair value of a share-based payment award using an option-pricing model requires the input of significant assumptions, such as the expected life of the award and stock price volatility.

Under the provisions of this FASB topic, we recognize expense for all share-based awards granted on a straight-line basis over the requisite service periods of the awards, which is generally equivalent to the vesting term. This topic requires compensation expense to be recognized such that compensation expense is recorded only for those awards expected to vest. As a result, we periodically review the amount of actual forfeitures and record any adjustments deemed necessary each reporting period. We also recognize excess tax benefits in our provision for income taxes. These excess tax benefits result from tax deductions in excess of the cumulative compensation expense recognized for options exercised and other equity-classified awards.

Additionally, this FASB topic amended FASB Topic Statement of Cash Flows to require excess tax benefits to be classified along with other income tax cash flows as an operating activity. In addition, cash flows related to employee taxes paid for withheld shares are classified as a financing activity.

See Note 10 for a further discussion of stock-based compensation.

Recently Adopted Accounting Standards

In April 2015, the Financial Accounting Standards Board ("FASB") issued an update to the Topic Interest – Imputation of Interest. This update simplifies the presentation of debt issuance costs by requiring debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, rather than recognizing debt issuance costs as an asset. On January 1, 2016, we adopted this update, which required retrospective application and resulted in the reclassification of $6.7 million of unamortized debt issuance costs related to the Company's Credit Agreement from other non-current assets to a reduction in long-term debt within the consolidated balance sheet as of December 31, 2015. Other than reclassification within the balance sheet, the adoption of this update had no further impact on our financial position, results of operations or cash flows.

In March 2016, the FASB issued an update to the Topic Compensation – Stock Compensation, which identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax reporting implications, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. We early adopted this update in the quarter ended December 31, 2016, which requires us to reflect any adjustments as of January 1, 2016, the beginning of the annual period that includes the interim period of adoption.

Table of Contents

The primary impact of adoption was the recognition of excess tax benefits in our provision for income taxes rather than capital in excess of par value for all periods in the year ended December 31, 2016. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings as of January 1, 2016, where the cumulative effect of these changes are required to be recorded.

Additionally, we have elected to change the manner in which we account for forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period. Previously, we would recognize expense, net of an estimated forfeiture rate, for all share-based awards granted on a straight-line basis over the requisite service periods of the awards, which is generally equivalent to the vesting term. In conjunction with the early adoption of this Topic, we will now record forfeitures as they occur.

We elected to apply the presentation requirements for cash flows related to excess tax benefits retrospectively to all periods presented, which resulted in an increase to both net cash provided by operating activities and net cash used in financing activities of $0.4 million and $0.6 million for the years ended December 31, 2015 and 2014, respectively. The presentation requirements for cash flows related to employee taxes paid for withheld shares resulted in an increase to both net cash provided by operating activities and net cash used in financing activities of $4.6 million and $5.2 million for the years ended December 31, 2015 and 2014, respectively.

Adoption of the new standard resulted in the recognition of excess tax benefits in our provision for income taxes rather than capital in excess of par value of $0.8 million, $1.7 million and $2.3 million for the three, six and nine months ended March 31, 2016, June 30, 2016 and September 30, 2016, respectively, and impacted our previously reported quarterly results for fiscal year 2016 as follows:

New Accounting Standards

In May 2014, the FASB issued the Topic Revenue from Contracts with Customers, which supersedes the revenue recognition requirements in the Topic Revenue Recognition and most industry specific guidance. The core principle of this guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The

Table of Contents

guidance also outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied, as well as new, expanded disclosures.

In August 2015, the FASB deferred the effective date of this amendment until 2018. The FASB has also issued numerous technical corrections and improvements to update its guidance, which will become effective upon adoption. The update may be adopted either retrospectively to each prior period or as a cumulative-effect adjustment on the date of adoption.

We commenced our assessment of the standard and have developed a project plan to guide the implementation. This plan includes analyzing the standard's impact on our contract portfolio, comparing current accounting policies and practices to the requirements of the new standard and identifying potential differences from applying the requirements of the new standard to our contracts. While this assessment continues, we have not yet selected a transition method nor have we yet determined the effect of the standard on our financial statements.

In July 2015, the FASB issued an update to the Topic Inventory. This update requires reporting entities measuring inventories under the first-in, first-out or average cost methods to measure inventory at the lower of cost or net realizable value, where net realizable value is "estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation." Inventory was previously required to be measured at the lower of cost or market value, where the measurement of market value had several potential outcomes. This update will be effective for us in 2017. We do not expect the adoption of this update to have a material impact on our financial statements.

In February 2016, the FASB issued an update to the Topic Leases, which supersedes the lease reporting requirements in Topic Leases (previously "FAS 13"). This update requires that a lessee recognize on its balance sheet the assets and liabilities for all leases with lease terms of more than 12 months, along with additional qualitative and quantitative disclosures. The effect of leases in a consolidated statement of income and a consolidated statement of cash flows is expected to be largely unchanged. Accounting by lessors was not significantly impacted by this update. This update will be effective for us in 2019, with early adoption permitted. We are currently evaluating the impact of the adoption of this standard on our financial statements.

In October 2016, the FASB issued an update to the Topic Statement of Cash Flows. This update clarifies guidance on the classification and presentation of restricted cash in the statement of cash flows. Restricted cash will now be included in the cash and cash equivalent balances in the statement of cash flows. Reconciliations between the balance sheet and the statement of cash flows, along with additional disclosures if certain criteria are met, are now required as well. This ASU is applicable to us and will be effective for interim periods beginning in 2018, with early adoption permitted. This update will affect the presentation of restricted cash and cash equivalents on the statement of cash flows, but will otherwise not have a material impact to our financial statements.

NOTE 2 – ACQUISITIONS

GE Hitachi Nuclear Energy Canada Inc. Acquisition

On December 16, 2016, our subsidiary BWXT Canada Ltd. acquired the outstanding stock of the GE Hitachi Nuclear Energy Canada Inc. ("GEH-C") joint venture for CAD 157.9 million ($117.8 million U.S. Dollar equivalent), subject to customary working capital, cash and debt adjustments, which was renamed BWXT Nuclear Energy Canada Inc. ("NEC"). NEC is a leading supplier of nuclear fuel, fuel handling systems, tooling delivery systems and replacement components for CANDU reactors and has approximately 350 employees. NEC operates two facilities licensed by the CNSC to fabricate natural uranium fuel in Peterborough and Toronto, Ontario, Canada as well as a third facility in Arnprior, Ontario, Canada. NEC expands our current commercial nuclear products and services portfolio and allows us to leverage our technology-based competencies in offering new products and services related to plant life extensions as well as the ongoing maintenance of nuclear power generation equipment and is reported within our Nuclear Energy segment.

NOTE 3 – DISCONTINUED OPERATIONS

Spin-off of BWE

On June 30, 2015, we completed the spin-off of BWE to our stockholders through a stock distribution. BWE’s assets and business primarily consist of those that we previously reported as our Power Generation segment. In connection with the spin-off, our stockholders received 100% of the outstanding common stock of BWE. Prior to the completion of the spin-off, we made a cash payment to BWE totaling $132 million. In order to effect the distribution and govern our relationship with BWE after the distribution, we entered into a master separation agreement with BWE. In addition to the master separation agreement, we entered into other agreements with BWE in connection with the distribution, including a tax sharing agreement and transition services agreements.

Master Separation Agreement

The master separation agreement between us and BWE contains the key provisions relating to the separation of our former Power Generation business from us and the distribution of shares of BWE common stock. The master separation agreement identifies the assets that were transferred, liabilities that were assumed and contracts that were assigned to BWE by us or by BWE to us in the spin-off and describes how these transfers, assumptions and assignments occurred. Under the master separation agreement we also agreed to indemnify BWE against various claims and liabilities related to the past operation of our business (other than BWE’s business).

At the spin-off, we had outstanding performance guarantees for various projects executed by BWE in the normal course of business. These guarantees totaled $1,542 million and had expiration dates from 2015 to 2035. In February 2016, BWE notified us that we have been released from substantially all remaining performances guarantees. Accordingly, we reduced the outstanding liability and recorded a gain of approximately $9.3 million during the year ended December 31, 2016 as a component of other – net in our consolidated statement of income.

Tax Sharing Agreement

We and BWE have entered into an agreement providing for the sharing of taxes incurred before and after the distribution, various indemnification rights with respect to tax matters and restrictions to preserve the tax-free status of the distribution. Under the terms of the tax sharing agreement we entered into in connection with the spin-off, we will generally be responsible for 60% of any taxes imposed on us or BWE and its subsidiaries in the event that the spin-off and/or certain related preparatory transactions were to fail to qualify for tax-free treatment. However, if the spin-off and/or certain related preparatory transactions were to fail to qualify for tax-free treatment because of actions or failures to act by BWE, we would not be responsible for the related taxes associated with these actions. Conversely, if the spin-off and/or certain related preparatory transactions were to fail to qualify for tax-free treatment because of actions or failures to act by us, we would be responsible for all related taxes associated with these actions.

Table of Contents

Transition Services Agreements

Under the transition services agreements, we and BWE are providing each other certain transition services for a limited time. Such services include, among others, accounting, human resources, information technology, legal, risk management, tax and treasury services. In consideration for such services, we and BWE each pay fees to the other for the services provided, and those fees are generally in amounts intended to allow the party providing the services to recover its direct and indirect costs incurred in providing those services. The transition services agreements contain customary mutual indemnification provisions.

Nuclear Projects Business Disposition

In the first quarter of 2014, we announced that we would exit our Nuclear Energy segment’s Nuclear Projects business as it had lower margins and higher financial risks. Run-off operations for remaining projects were completed during the quarter ended June 30, 2014. Income (loss) before provision for income taxes for the Nuclear Projects business was $(4.5) million in the year ended December 31, 2014.

As of December 31, 2015, there were no assets or liabilities remaining from the Nuclear Projects business.

In accordance with FASB Topic Presentation of Financial Statements – Discontinued Operations, the results of operations of the Nuclear Projects business have been classified as continuing operations within the consolidated financial statements.

NOTE 4 – EQUITY METHOD INVESTMENTS

We have investments in entities that we account for using the equity method. The undistributed earnings of our equity method investees were $8.1 million and $6.4 million at December 31, 2016 and 2015, respectively.

On January 8, 2013, we were notified that our joint venture, Nuclear Production Partners, LLC, was not selected to lead the NNSA’s combined Management and Operating contract for the Y-12 National Security Complex and Pantex Plant. Subsequently, we filed multiple protests with the Government Accountability Office in relation to the selection decision. On February 27, 2014, we received notification that our latest protest was dismissed. The transition of these facilities to the new

contractor was completed on June 30, 2014, and is the primary cause of the decline in our equity method income for the periods ended December 31, 2016 and 2015.

Income taxes for the investees are the responsibility of the respective owners. Accordingly, no provision for income taxes has been recorded by the investees.

NOTE 5 – SPECIAL CHARGES FOR RESTRUCTURING ACTIVITIES

In 2014, we began certain initiatives aimed at driving margin improvement in our Nuclear Energy segment. As of June 30, 2015, these initiatives were substantially complete. In the year ended December 31, 2015, we incurred $0.7 million of expenses related to employee termination benefits and facility consolidation. In the year ended December 31, 2014, we incurred $9.9 million of expenses related to this project, including $3.4 million of expenses related to employee termination benefits and $6.5 million of expenses related to facility consolidation.

In the year ended December 31, 2015, we also incurred $15.9 million of expenses related to the restructuring of our mPower program, consisting primarily of asset impairments as a result of the significant adverse changes in the business prospects of the mPower program. In the year ended December 31, 2014, we also incurred $10.6 million of expenses related to the restructuring of our mPower program, including $7.3 million of expenses related to employee termination benefits, $3.0 million of expenses related to consulting and administrative costs and $0.3 million of expenses related to facility consolidation.

Additionally, we incurred expenses related to employee termination benefits totaling $0.4 million for the year ended December 31, 2014 related to restructuring of our Technical Services segment.

NOTE 6 – INCOME TAXES

We are subject to federal income tax in the U.S. and Canada as well as income tax within multiple U.S. state jurisdictions. We provide for income taxes based on the enacted tax laws and rates in the jurisdictions in which we conduct our operations. These jurisdictions may have regimes of taxation that vary with respect to nominal rates and with respect to the basis on which these rates are applied. This variation, along with the changes in our mix of income within these jurisdictions, can contribute to shifts in our effective tax rate from period to period.

With the spin-off of our former Power Generation business in the second quarter of 2015, we began recognizing our consolidated income tax provision based on the U.S. federal statutory rate of 35% due to the presumed repatriation of our Canadian earnings. With the acquisition of NEC in the fourth quarter of 2016, we now believe that we have sufficient evidence to support indefinite foreign reinvestment, and therefore, for the year ending December 31, 2016, we are asserting that any undistributed foreign earnings are indefinitely reinvested. With this change, we have recorded our current year Canadian tax provision based on the Canadian local statutory rate of approximately 25%.

We are currently under audit by various state and international authorities. With few exceptions, we do not have any returns under examination for years prior to 2012.

We apply the provisions of FASB Topic Income Taxes regarding the treatment of uncertain tax positions. A reconciliation of unrecognized tax benefits (exclusive of interest and federal/state benefit) is as follows:



	Year Ended December 31,
	2016			2015			2014
	(In thousands)
Balance at beginning of period	$	2,222		$	8,597		$	4,943
Increases based on tax positions taken in the current year	—			185			868
Increases based on tax positions taken in the prior years	—			—			3,396
Decreases based on tax positions taken in the prior years	—			(134		)	(260		)
Decreases due to settlements with tax authorities	(571		)	(5,934		)	(350		)
Decreases due to lapse of applicable statute of limitation	—			(492		)	—
Balance at end of period	$	1,651		$	2,222		$	8,597

The unrecognized tax benefits balance of $1.7 million (exclusive of interest and federal/state benefit) at December 31, 2016 would reduce our effective tax rate if recognized.

We believe that, within the next 12 months, it is reasonably possible that our previously unrecognized tax benefits could decrease by $0.9 million.

At December 31, 2016, we had a valuation allowance of $17.2 million for deferred tax assets, which we expect cannot be realized through carrybacks, future reversals of existing taxable temporary differences and our estimate of future taxable income. We believe that our remaining deferred tax assets are more likely than not realizable through carrybacks, future reversals of existing taxable temporary differences and our estimate of future taxable income. Any changes to our estimated valuation allowance could be material to our consolidated financial statements.

The following is an analysis of our valuation allowance for deferred tax assets:

valuation allowance of $7.4 million ($4.8 million net of federal tax benefit) against the deferred tax asset related to the state loss carryforwards.

We would be subject to withholding taxes if we were to distribute earnings from certain foreign subsidiaries. For the year ended December 31, 2016, the undistributed earnings of these subsidiaries were approximately $52.6 million. Unrecognized deferred income tax liabilities, including withholding taxes, of approximately $9.5 million would be payable upon the distribution of these earnings. All of our foreign earnings are considered permanently reinvested.

NOTE 8 – PENSION PLANS AND POSTRETIREMENT BENEFITS

We have historically provided defined benefit retirement benefits, primarily through noncontributory pension plans, for most of our regular employees. As of 2006, our retirement plans for U.S.-based employees were closed to new entrants for our corporate employees and were closed to new salaried plan entrants for our existing plans. The plans have also been closed to new hourly employees at certain locations.

Effective December 31, 2015, benefit accruals for salaried employees covered by and continuing to accrue service and salary adjusted benefits under our major U.S. and Canadian defined benefit qualified pension plans ceased. Furthermore, effective January 1, 2016, we began making service-based, cash contributions to a defined contribution plan for those employees impacted by the plan freeze.

Effective January 1, 2012, a defined contribution component was adopted applicable to BWXT Canada, Ltd. (the "Canadian Plans"). Any employee with less than two years of continuous service as of December 31, 2011 was enrolled in the defined contribution component of the Canadian Plans as of January 1, 2012 or upon the completion of six months of continuous service, whichever is later. These and future employees will not be eligible to enroll in the defined benefit component of the Canadian Plans. Additionally, during the third quarter of 2014, benefit accruals under certain hourly Canadian pension plans were ceased with an effective date of January 1, 2015. This amendment to the Canadian Plans is reflected as a curtailment in 2014.

We do not provide retirement benefits to certain non-resident alien employees of foreign subsidiaries. Retirement benefits for salaried employees who accrue benefits in a defined benefit plan are based on final average compensation and years of service, while benefits for hourly paid employees are based on a flat benefit rate and years of service. Our funding policy is to fund the plans as recommended by the respective plan actuaries and in accordance with the Employee Retirement Income Security Act of 1974, as amended, or other applicable law. The Pension Protection Act of 2006 became effective in 2008. Funding provisions under the Pension Protection Act accelerate funding requirements to ensure full funding of benefits accrued. Assuming we continue as a government contractor, our contractual arrangements with the U.S. Government provide for the recovery of contributions to our pension and other postretirement benefit plans covering employees working primarily in our Nuclear Operations segment.

We make available other benefits which include postretirement health care and life insurance benefits to certain salaried and union retirees based on their union contracts. Certain subsidiaries provide these benefits to unionized and salaried future retirees.

Beginning in the first quarter of 2016, we changed the method we use to estimate the interest and service cost components of our net periodic benefit cost for our pension and postretirement benefit plans. Previously, we estimated interest and service cost utilizing a single weighted-average discount rate derived from the yield curve data used to measure the benefit obligation. Our new method for estimating interest and service cost is a spot rate approach, which utilizes duration specific spot rates from the yield curve that was used to measure the benefit obligation.

Our combined service and interest cost for our pension and postretirement plans decreased $25.7 million in the year ended December 31, 2016. The decrease is attributable to the change in the method used to estimate the service and interest cost components of net periodic benefit cost discussed above. While this change in estimate provides a more precise estimate of service and interest cost by improving the relationship of the discount rates utilized to measure our benefit obligation and the rates utilized to estimate service and interest cost, this change will not affect the measurement of our total pension and postretirement benefit obligations or our total annual net periodic benefit cost as the change in our service and interest cost will be offset in our recognized net actuarial (gain) loss recognized in the fourth quarter each year. Service cost also decreased due to the December 31, 2015 plan freeze of our major U.S. and Canadian defined benefit qualified pension plans.

Net periodic benefit cost related to our pension plans is calculated in accordance with GAAP. In addition, we calculate pension costs in accordance with U.S. cost accounting standards ("CAS") for purposes of cost recovery on our U.S. Government contracts to the extent applicable. See further discussion of CAS pension costs in our discussion of Critical Accounting Policies and Estimates included in Item 7 of this report.

Recognized net actuarial loss (gain) consists primarily of our reported actuarial loss (gain), curtailments, and the difference between the actual return on plan assets and the expected return on plan assets. Additionally, we adjusted our mortality assumption in the year ended December 31, 2014, resulting in a $70.9 million increase in our pension liability. As discussed in Note 17, we have excluded the recognized net actuarial loss (gain) from our reportable segments and such amount has been reflected in Note 17 as the Mark to Market Adjustment in the reconciliation of reportable segment income to consolidated operating income. The recognized net actuarial loss (gain) and the affected consolidated statements of income line items are as follows:

Assumptions

	2016		2015		2016		2015
Weighted average assumptions used to determine net periodic benefit obligations at December 31:
Discount rate	4.18	%	4.27	%	4.12	%	4.24	%



	Pension Benefits						Other Benefits
	2016		2015		2014		2016		2015		2014
Weighted average assumptions used to determine net periodic benefit cost for the years ended December 31:
Discount rate	4.27	%	4.00	%	4.78	%	4.22	%	3.91	%	4.63	%
Expected return on plan assets	7.03	%	7.04	%	7.02	%	5.71	%	5.72	%	5.73	%
Rate of compensation increase	—		2.57	%	2.60	%	—		—		—

The expected rate of return on plan assets assumption is based on the long-term expected returns for the investment mix of assets currently in the portfolio. In setting this rate, we use a building-block approach. Historic real return trends for the various asset classes in the plan's portfolio are combined with anticipated future market conditions to estimate the real rate of return for each class. These rates are then adjusted for anticipated future inflation to determine estimated nominal rates of return for each class. The expected rate of return on plan assets is determined to be the weighted average of the nominal returns based on the weightings of the classes within the total asset portfolio. We are using an expected return on plan assets assumption of 7.2% for the majority of our existing pension plan assets (approximately 89% of our total pension assets at December 31, 2016).

Our existing other benefit plans are unfunded, with the exception of the NFS postretirement benefit plans. These plans provide health benefits to certain salaried and hourly employees, as well as retired employees, of NFS. All of the assets for these postretirement benefit plans are contributed into a Voluntary Employees' Beneficiary Association trust.

Investment Goals

General

The overall investment strategy of the pension trusts is to achieve long-term growth of principal, while avoiding excessive risk and to minimize the probability of loss of principal over the long term. The specific investment goals that have been set for the pension trusts in the aggregate are (1) to ensure that plan liabilities are met when due and (2) to achieve an investment return on trust assets consistent with a reasonable level of risk.

Allocations to each asset class for both domestic and foreign plans are reviewed periodically and rebalanced, if appropriate, to assure the continued relevance of the goals, objectives and strategies. The pension trusts for both our domestic and foreign plans employ a professional investment advisor and a number of professional investment managers whose individual benchmarks are, in the aggregate, consistent with the plan's overall investment objectives.

The goals of each investment manager are (1) to meet (in the case of passive accounts) or exceed (for actively managed accounts) the benchmark selected and agreed upon by the manager and the pension trust and (2) to display an overall level of risk in its portfolio that is consistent with the risk associated with the agreed upon benchmark.

The investment performance of total portfolios, as well as asset class components, is periodically measured against commonly accepted benchmarks, including the individual investment manager benchmarks. In evaluating investment manager performance, consideration is also given to personnel, strategy, research capabilities, organizational and business matters, adherence to discipline and other qualitative factors that may impact the ability to achieve desired investment results.

Domestic Plans

We sponsor the following domestic defined benefit plans:


•	BWXT Retirement Plan;


•	Nuclear Fuel Services, Inc. Retirement Plan for Salaried Employees; and


•	Nuclear Fuel Services, Inc. Retirement Plan for Hourly Employees.

The assets of the domestic pension plans are commingled for investment purposes and held by the trustee in the BWXT Master Trust (the "Master Trust"). For the years ended December 31, 2016 and 2015, the investment return on domestic plan assets of the Master Trust (net of deductions for management fees) was approximately 9% and (1)%, respectively.

In accordance with FASB Topic Fair Value Measurements, certain investments that were measured at NAV per share (or its equivalent) have not been classified in the fair value hierarchy. These investments are measured on the fair value of the underlying investments but may not be redeemable at that fair value. When appropriate, we adjust these net asset values for contributions and distributions, if any, made during the period beginning on the latest NAV valuation date and ending on our measurement date. We also consider available market data, relevant index returns, preliminary estimates from our investees and other data obtained through research and consultation with third-party advisors in determining the fair value of these investments.

Defined Contribution Plans

We provide benefits under the Supplemental Executive Retirement Plan of BWX Technologies, Inc. (the "SERP Plan"), which is a defined contribution plan. We recorded expense related to the SERP Plan of approximately $0.0 million, $0.4 million and $0.5 million in the years ended December 31, 2016, 2015 and 2014, respectively.

We also provide benefits under the BWXT Thrift Plan (the "Thrift Plan"). The Thrift Plan generally provides for matching employer contributions of 50% of the first 6% of compensation, as defined in the Thrift Plan, contributed by participants, and fully vest and are nonforfeitable after three years of service or upon retirement, death, lay-off or approved disability. Starting May 15, 2015, these matching employer contributions are made in cash and invested at the employees' discretion. Previously, matching contributions were provided in the form of Company stock. We also provide service-based cash contributions under the Thrift Plan to employees not accruing benefits under our defined benefit plans. Amounts charged to expense for employer contributions under the Thrift Plan totaled approximately $26.0 million, $17.5 million and $18.1 million in the years ended December 31, 2016, 2015 and 2014, respectively.

Effective January 1, 2012, we adopted The BWX Technologies, Inc. Defined Contribution Restoration Plan (the "Restoration Plan") to restore benefits that would be provided to participants in the Thrift Plan but are precluded by the application of certain sections of the Internal Revenue Code of 1986, as amended (the "Code"). Each participant who is precluded from receiving the full amount of service-based contributions otherwise provided under the Thrift Plan in a plan year by the application of Code Section 401(a)(17) or 415(c) shall be credited with an employer service-based contribution for such plan year equal to the excess of the amount of service-based contributions that would have been made to the participant's Thrift Plan account without the application of Code Section 401(a)(17) and 415(c) for the plan year over the amount of service-based contribution actually made to such participant's Thrift Plan account for the plan year. In addition, the Restoration Plan permits participants who are precluded from making the full amount of employee contributions to the Thrift Plan and receiving associated employer matching contributions by the application of Code Sections 401(a)(17) and 415(c) to elect to make deferral contributions and receive associated employer matching contributions under the Restoration Plan. Amounts charged to expense under the Restoration Plan totaled approximately $0.2 million, $0.1 million and $0.2 million in the years ended December 31, 2016, 2015 and 2014, respectively.

Effective January 1, 2012, a defined contribution component was added to those Canadian Plans previously offering defined benefits to salaried employees. As of January 1, 2012, we made cash, service-based contributions under this arrangement. The amount charged to expense for employer contributions was approximately $1.1 million, $0.7 million and $0.3 million in the years ended December 31, 2016, 2015 and 2014, respectively.

NOTE 9 – CAPITAL STOCK

In May 2013, our Board of Directors authorized us to repurchase an indeterminate number of shares of our common stock at an aggregate market value of up to $250 million that expired on December 10, 2015. In February 2014, our Board of Directors authorized an additional aggregate market value repurchase of our common stock of up to $250 million that expired on February 26, 2016. On October 30, 2015, our Board of Directors authorized an additional share repurchase of up to an aggregate market value of $300 million during a two-year period from February 26, 2016 to February 26, 2018.

In the year ended December 31, 2016, we repurchased 7,025,203 shares of common stock for approximately $292.9 million, which only includes the partial shares received under the September 2016 accelerated share repurchase agreement (the "ASR Agreement") discussed below. In the year ended December 31, 2015, we repurchased 2,429,016 shares of common stock for approximately $69.7 million, and in the year ended December 31, 2014, we repurchased 4,687,500 shares of common stock for approximately $149.7 million. As of December 31, 2016, we had approximately $43.0 million available to us for share repurchase under the $300 million authorization described above.

Table of Contents

On September 15, 2016, the Company entered into a $200 million ASR Agreement with Wells Fargo Bank, National Association ("Wells Fargo"). Pursuant to the terms of the ASR Agreement, on September 16, 2016, the Company paid Wells Fargo $200 million in cash and received 4,135,435 shares of the Company’s common stock. The final number of shares to be repurchased will be based on the volume-weighted average stock price of the Company’s common stock during the term of the ASR Agreement, less a customary discount. At settlement, under certain circumstances, Wells Fargo may be required to deliver additional shares of common stock to the Company, or under certain circumstances, the Company may be required to deliver shares of common stock or to make a cash payment, at its election, to Wells Fargo. Final settlement of the ASR Agreement is expected to be completed in the first quarter of 2017.

The initial repurchase of shares under the ASR Agreement resulted in an immediate reduction of the outstanding shares used to calculate the weighted-average common shares outstanding for basic and diluted earnings per share. The ASR Agreement was accounted for as a treasury stock transaction and forward stock purchase contract. The shares delivered were recorded in treasury stock and the unsettled portion of the ASR Agreement was recorded in capital in excess of par value in the Company’s consolidated balance sheet. The forward stock purchase contract is considered indexed to the Company’s own stock and is classified as an equity instrument.

NOTE 10 – STOCK-BASED COMPENSATION

2010 Long-Term Incentive Plan of BWX Technologies, Inc.

Members of the Board of Directors, executive officers, key employees and consultants are eligible to participate in the 2010 Long-Term Incentive Plan of BWX Technologies, Inc. (the "Plan"). The Compensation Committee of the Board of Directors selects the participants for the Plan. The Plan provides for a number of forms of stock-based compensation, including incentive and non-qualified stock options, restricted stock, restricted stock units, performance shares and performance units, subject to satisfaction of specific performance goals. Shares subject to awards under the Plan that are cancelled, forfeited, terminated or expire unexercised, shall immediately become available for the granting of awards under this Plan. As part of the approval of the Plan, 10,000,000 shares of common stock were initially authorized for issuance through the Plan, with an additional 2,300,000 authorized for issuance during the year ended December 31, 2014. Options to purchase shares are granted at not less than 100% of the fair market value closing price on the date of grant, become exercisable at such time or times as determined when granted and expire not more than ten years after the date of grant.

At December 31, 2016, we had awarded 8,320,038 shares under the Plan and had a total of 3,979,962 shares of our common stock available for future awards. In the event of a change in control of our company, the terms of the awards under the Plan contain provisions that may cause restrictions to lapse and accelerate the vesting of plan awards.

Long-Term Incentive Plan of BWXT Technical Services Group, Inc.

In June 2012, we established the 2012 Long-Term Incentive Plan of BWXT Technical Services Group, Inc., a cash-settled plan for employees of certain subsidiaries and unconsolidated affiliates as selected by the plan committee. The cash-settled plan provides for a number of forms of stock-based compensation, including stock appreciation rights, restricted stock units and performance units, subject to satisfaction of specific performance goals. Stock appreciation rights are granted at not less than 100% of the fair market value closing price of a share of BWXT common stock on the date of grant, become exercisable at such time or times as determined when granted and expire not more than ten years after the date of grant. Stock appreciation rights are cash settled for the excess of the market price of BWXT common stock on the exercise date minus the exercise price. Restricted stock units and performance units are cash settled upon vesting as determined when granted. We will not issue any shares of BWXT common stock under this plan, as all awards are cash settled.

In the event of a change in control of our company, the terms of the awards under the cash-settled plan contain provisions that may cause restrictions to lapse and accelerate the vesting of plan awards.

Impact of the Spin-off on our Equity-Based Compensation Awards

In connection with the spin-off of BWE, in accordance with the provisions of the Plan, conversion adjustments were made to our outstanding non-qualified stock options, performance shares and restricted stock units. The conversion of these awards was designed to preserve the intrinsic value of the original award which resulted in no incremental compensation expense. The awards continue to vest over the original vesting period, and to the extent that the adjusted awards had previously vested, the adjusted awards are also vested.

Table of Contents

Each outstanding option or restricted stock unit award that was granted during 2015 to officers or employees of the Company who remained officers or employees of BWXT was replaced with an adjusted BWXT award. In addition, each outstanding option or restricted stock unit award that was granted during 2015 to a person who became an officer or employee of BWE immediately after the spin-off was replaced with a substitute BWE award.

Outstanding options or restricted stock units that were granted prior to 2015 were replaced with both an adjusted BWXT award and a substitute BWE award. Outstanding performance share awards granted prior to 2015 were converted into unvested restricted stock units of both BWXT and BWE.

Total stock-based compensation expense for all of our plans recognized for the years ended December 31, 2016, 2015 and 2014 totaled $16.8 million, $25.9 million and $8.6 million, respectively, with associated tax benefit recognized for the years ended December 31, 2016, 2015 and 2014 totaling $6.0 million, $9.0 million and $2.7 million, respectively. Included in stock-based compensation expense for the year ended December 31, 2016 is $3.3 million associated with an executive reorganization that resulted in the acceleration of previously granted equity awards. We recognized $13.2 million of stock-based compensation expense during the year ended December 31, 2015 as costs to spin-off our former Power Generation business. This expense related primarily to equity retention awards and expense acceleration associated with employee terminations.

As of December 31, 2016, unrecognized estimated compensation expense related to nonvested awards was $13.8 million, which is expected to be recognized over a weighted-average period of 1.9 years.

BWXT Stock Options

The fair value of each option grant was estimated at the date of grant using Black-Scholes, with the following weighted-average assumptions:



	Year Ended December 31,
	2015		2014
Risk-free interest rate	1.33	%	0.97	%
Expected volatility	.29		.30
Expected life of the option in years	4.04		3.76
Expected dividend yield	1.27	%	1.22	%

The risk-free interest rate is based on the implied yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected life of the option. The expected volatility is based on implied volatility from publicly traded options on our common stock, historical volatility of the price of our common stock and other factors. The expected life of the option is based on observed historical patterns. The expected dividend yield is based on the projected annual dividend payment per share divided by the stock price at the date of grant.

The following table summarizes activity for our stock options for the year ended December 31, 2016 (share data in thousands):



	Number of Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value (in millions)

The aggregate intrinsic value included in the table above represents the total pre-tax intrinsic value that would have been received by the option holders had all option holders exercised their options on December 31, 2016. The intrinsic value is calculated as the total number of option shares multiplied by the difference between the closing price of our common stock on the last trading day of the period and the exercise price of the options. This amount changes based on the price of our common stock.

There were no stock options granted during 2016. The weighted-average fair value of the stock options granted in the years ended December 31, 2015 and 2014 was $6.59 and $7.03, respectively.

During the years ended December 31, 2016, 2015 and 2014, the total intrinsic value of stock options exercised was $12.0 million, $3.3 million and $2.1 million, respectively. The actual tax benefits realized related to the stock options exercised during the year ended December 31, 2016 was $2.3 million.

BWXT Performance Shares

Nonvested performance shares as of December 31, 2016 and changes during the year ended December 31, 2016 were as follows (share data in thousands):



	Number of Shares		Weighted- Average Grant Date Fair Value

Cash-Settled Stock Appreciation Rights

The fair value of each stock appreciation right grant was calculated at the grant date using Black-Scholes and was remeasured at the end of the reporting period with the following weighted-average assumptions:



	Year Ended December 31,
	2015		2014
Risk-free interest rate	0.99	%	0.61	%
Expected volatility	.20		.23
Expected life of the option in years	1.21		0.21
Expected dividend yield	0.94	%	0.94	%

The risk-free interest rate is based on the implied yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected life of the stock appreciation right. The expected volatility is based on implied volatility from publicly traded options on our common stock, historical volatility of the price of our common stock and other factors. The expected life of the stock appreciation right is based on observed historical patterns and the length of time each award has been outstanding as of each measurement date. The expected dividend yield is based on the projected annual dividend payment per share divided by the stock price at the date of measurement.

The following table summarizes activity for our stock appreciation rights for the year ended December 31, 2016 (unit data in thousands):



	Number of Units		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value (in millions)
Outstanding at beginning of period	119		$	23.04

Outstanding at end of period	99		$	23.14	5.8 Years	$	1.6
Exercisable at end of period	57		$	22.55	4.8 Years	$	1.0

The aggregate intrinsic value included in the table above represents the total pre-tax intrinsic value that would have been received by the stock appreciation rights holders had all holders exercised their rights on December 31, 2016. The intrinsic value is calculated as the total number of stock appreciation rights multiplied by the difference between the closing price of our common stock on the last trading day of the period and the exercise price of the stock appreciation rights. This amount changes based on the price of our common stock.

NOTE 11 – COMMITMENTS AND CONTINGENCIES

Investigations and Litigation

Apollo and Parks Township

In January 2010, Michelle McMunn, Cara D. Steele and Yvonne Sue Robinson filed suit against Babcock & Wilcox Power Generation Group, Inc. ("B&W PGG"), Babcock & Wilcox Technical Services Group, Inc., formerly known as B&W Nuclear Environmental Services, Inc. and now known as BWXT Technical Services Group, Inc. (the "BWXT Parties") and Atlantic Richfield Company ("ARCO") in the U.S. District Court for the Western District of Pennsylvania. Since January 2010, additional suits were filed by additional plaintiffs and there are currently 17 lawsuits pending in the U.S. District Court for the

Table of Contents

Western District of Pennsylvania against the BWXT Parties and ARCO, including the most recent lawsuits filed in June and October 2015. In total, the suits presently involve approximately 107 primary claimants. The primary claimants allege, among other things, personal injuries and property damage as a result of alleged releases of radioactive material relating to the operation, remediation and/or decommissioning of two former nuclear fuel processing facilities located in the Borough of Apollo and Parks Township, Pennsylvania (collectively, the "Apollo and Parks Litigation"). Those facilities previously were owned by Nuclear Materials and Equipment Company, a former subsidiary of ARCO ("NUMEC"), which was acquired by B&W PGG. The plaintiffs in the Apollo and Parks Litigation seek compensatory and punitive damages, and in November 2014 delivered a demand of $125.0 million for the settlement of all then-filed actions. While we consider the likelihood of the plaintiffs' recovery to be remote, solely on the basis of this demand we estimate the range of a possible loss at between $0.0 million and $125.0 million. In connection with the spin-off, we agreed to indemnify B&W PGG and its affiliates for any losses arising from the Apollo and Parks Litigation pursuant to the Master Separation Agreement.

Between May 2015 and March 2016, the presiding judge in the Apollo and Parks Litigation granted the BWXT Parties' motions to dismiss or motions for summary judgment in all 17 of the existing lawsuits. Accordingly, all current claims in the Apollo and Parks Litigation have been dismissed by the trial court. All plaintiffs have filed notices of appeal, and the appeals have been consolidated in the 3^rd Circuit of the U.S. Court of Appeals. Although the appeal process could be lengthy, if ultimately upheld the trial court's decisions would result in the dismissal of all 17 law suits.

At the time of ARCO’s sale of NUMEC stock to B&W PGG, B&W PGG received an indemnity and hold harmless agreement from ARCO, which has been assigned to BWXT and its affiliates, with respect to claims and liabilities arising prior to or as a result of conduct or events predating the acquisition.

Insurance coverage and/or the ARCO indemnity currently provides coverage for the claims alleged in the Apollo and Parks Litigation, although no assurance can be given that insurance and/or the indemnity will be available or sufficient in the event of liability, if any.

mPower

In April 2014, BWXT announced plans to restructure our mPower program for the development of our mPower reactor to focus on technology development. Since then, BWXT has worked with the DOE, Bechtel - our partner in GmP - and other stakeholders and potential investors in continuing efforts to restructure the mPower program in light of deteriorated market conditions. Although BWXT has continued to invest in the program during 2014 and 2015 at the rate of approximately $15.0 million annually, on July 13, 2015, Bechtel provided a written notice asserting that BWXT and GmP were in material breach of the GmP Limited Liability Company Agreement dated February 28, 2011 (the “GmP LLC Agreement”). BWXT asserted, among other things, that it had the right under the LLC Agreement to terminate the mPower program and Bechtel was therefore not entitled to any return of its investment. In October 2015, BWXT and Bechtel agreed to a 60-day period of negotiations for the purpose of negotiating a resolution of these matters, which was subsequently extended.

On March 2, 2016, BWXT entered into a Framework Agreement with Bechtel, BWXT Modular Reactors, LLC and BDC NexGen Power, LLC for the potential restructuring and restart of our mPower program (the "Framework Agreement"). The Framework Agreement provides that during a 12-month fundraising period beginning on the effective date of the Framework Agreement, Bechtel will attempt to secure funding from third parties (including the DOE) to complete development of the mPower Plant design sufficient to achieve design certification by the U.S. Nuclear Regulatory Commission. During this fundraising period, BWXT plans to continue advancing the mPower design through in-kind engineering services within our previously announced planned mPower project spending of no more than $10.0 million per year.

If Bechtel is successful in securing adequate commitments of funding from external sources (as determined by Bechtel in its sole discretion), then the Framework Agreement requires (a) BWXT and Bechtel to negotiate and execute a new GmP limited liability company agreement and ancillary-related agreements, with Bechtel taking over management of the mPower program from BWXT, and (b) BWXT to fund an aggregate of $60.0 million in in-kind development costs toward achieving design certification (not to exceed $12.0 million per year).

In the event that Bechtel determines in its sole discretion that the mPower program should not be restarted, whether due to (1) adequate third party funding not being secured, (2) the parties being unable to finalize the new GmP limited liability company agreement and other related ancillary agreements, or (3) otherwise, the mPower program would be terminated, GmP would be dissolved and Bechtel would be entitled to payment of a settlement amount of $30.0 million (the “Settlement Amount”). Our sole liability and Bechtel’s sole remedy arising out of the Framework Agreement will be our obligation to pay, and Bechtel’s right to receive, respectively, the Settlement Amount. Any and all other previously existing claims, demands or actions between Bechtel and us arising out of the GmP LLC Agreement and related ancillary agreements, whether known or

Table of Contents

unknown (including Bechtel’s previously asserted breach claim for $120.0 million), were released upon our delivery of a letter of credit equal in value to the Settlement Amount on March 2, 2016.

In the year ended December 31, 2016, we recognized the $30.0 million potential Settlement Amount as a component of accrued liabilities – other in our consolidated balance sheet, payment of which is contingent upon determination in Bechtel’s sole discretion not to restart the mPower program. In addition, provisions of the Framework Agreement resulted in the deconsolidation of GmP and the associated recognition of an approximate $13.6 million gain upon deconsolidation.

As BWXT has previously disclosed, the latest extension to the Cooperative Agreement with the DOE has expired, and the DOE funding has been suspended.

Other Litigation and Settlements

Due to the nature of our business, we are, from time to time, involved in routine litigation or subject to disputes or claims related to our business activities, including, among other things:


•	performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and


•	workers’ compensation claims, premises liability claims and other claims.

Based upon our prior experience, we do not expect that any of these other litigation proceedings, disputes and claims will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

Environmental Matters

We have been identified as a potentially responsible party at various cleanup sites under the Comprehensive Environmental Response, Compensation, and Liability Act, as amended ("CERCLA"). CERCLA and other environmental laws can impose liability for the entire cost of cleanup on any of the potentially responsible parties, regardless of fault or the lawfulness of the original conduct. Generally, however, where there are multiple responsible parties, a final allocation of costs is made based on the amount and type of wastes disposed of by each party and the number of financially viable parties, although this may not be the case with respect to any particular site. We have not been determined to be a major contributor of wastes to any of these sites. On the basis of our relative contribution of waste to each site, we expect our share of the ultimate liability for the various sites will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows in any given year.

The Department of Environmental Protection of the Commonwealth of Pennsylvania ("PADEP") advised us in March 1994 that it would seek monetary sanctions and remedial and monitoring relief related to the former production facility located in Parks Township, Pennsylvania (the "Parks Facility"). The relief sought was related to potential groundwater contamination resulting from previous operations at the facility. The Parks Facility was decommissioned in the 1990s, including facilities dismantlement and soil restoration. The NRC terminated the Parks Facility license in 2004 and released the facility for unrestricted use. What remains of the Parks Facility is currently owned by a subsidiary in our Nuclear Operations segment. Based on favorable results from groundwater sampling completed by our Nuclear Operations segment, we have sought approval by PADEP for release of the property, subject to limitations on future use, under Pennsylvania’s voluntary clean-up program.

We perform significant amounts of work for the U.S. Government under both prime contracts and subcontracts and operate certain facilities that are licensed to possess and process special nuclear materials. As a result of these activities, we are subject to continuing reviews by governmental agencies, including the U.S. Environmental Protection Agency and the NRC. We are also involved in the design and manufacture of commercial nuclear fuel at two licensed facilities in Canada that are also subject to continuing reviews by governmental agencies in Canada, including the CNSC.

The NRC’s decommissioning regulations require our Nuclear Operations segment to provide financial assurance that it will be able to pay the expected cost of decommissioning each of its licensed facilities at the end of its service life. We provided financial assurance aggregating $56.2 million and $52.3 million during the years ended December 31, 2016 and 2015, respectively, with existing letters of credit for the ultimate decommissioning of these licensed facilities. These two facilities have provisions in their government contracts pursuant to which substantially all of our decommissioning costs and financial assurance obligations are covered by the DOE, including the costs to complete the decommissioning projects underway at the

Table of Contents

facility in Erwin, Tennessee. These letters of credit are to cover decommissioning required pursuant to work not subject to this DOE obligation.

In Canada, the CNSC’s decommissioning regulations require our Nuclear Energy segment to provide financial assurance that it will be able to pay the expected cost of decommissioning its two CNSC-licensed facilities at the end of their service lives. We provided financial assurance totaling $39.5 million during the year ended December 31, 2016 with a letter of credit for the ultimate decommissioning of these licensed facilities.

Our compliance with U.S. federal, state and local environmental control and protection regulations resulted in pre-tax charges of approximately $14.2 million, $14.1 million and $13.2 million in the years ended December 31, 2016, 2015 and 2014, respectively. In addition, compliance with existing environmental regulations necessitated capital expenditures of $1.3 million, $0.7 million and $0.3 million in the years ended December 31, 2016, 2015 and 2014, respectively. At December 31, 2016 and 2015, we had total environmental accruals (including provisions for the facilities discussed above) of $86.3 million and $63.4 million, respectively. Of our total environmental accruals at December 31, 2016 and 2015, $4.6 million and $3.2 million, respectively, were included in current liabilities. Inherent in the estimates of those accruals and recoveries are our expectations regarding the levels of contamination, decommissioning costs and recoverability from other parties, which may vary significantly as decommissioning activities progress. Accordingly, changes in estimates could result in material adjustments to our operating results, and the ultimate loss may differ materially from the amounts that we have provided for in our consolidated financial statements.

Operating Leases

Future minimum payments required under operating leases that have initial or remaining noncancellable lease terms in excess of one year at December 31, 2016 are as follows (in thousands):

Total rental expense for the years ended December 31, 2016, 2015 and 2014 was $4.6 million, $4.9 million and $6.2 million, respectively.

NOTE 12 – RISKS AND UNCERTAINTIES

Percentage-of-Completion Accounting

As of December 31, 2016, in accordance with the percentage-of-completion method of accounting, we have provided for our estimated costs to complete all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. The risk on fixed-priced contracts is that revenue from the customer does not cover increases in our costs. It is possible that current estimates could materially change for various reasons, including, but not limited to, fluctuations in forecasted labor productivity or steel and other raw material prices. Increases in costs on our fixed-price contracts could have a material adverse impact on our consolidated financial condition, results of operations and cash flows. Alternatively, reductions in overall contract costs at completion could materially improve our consolidated financial condition, results of operations and cash flows.

Insurance

Upon the February 22, 2006 effectiveness of the settlement relating to the Chapter 11 proceedings involving several of our subsidiaries, most of our subsidiaries contributed substantial insurance rights to the asbestos personal injury trust, including rights to (1) certain pre-1979 primary and excess insurance coverages and (2) certain of our 1979-1986 excess insurance coverage. These insurance rights provided coverage for, among other things, asbestos and other personal injury claims, subject to the terms and conditions of the policies. The contribution of these insurance rights was made in exchange for the agreement on the part of the representatives of the asbestos claimants, including the representative of future claimants, to the entry of a permanent injunction, pursuant to Section 524(g) of the U.S. Bankruptcy Code, to channel to the asbestos trust all asbestos-

Table of Contents

related claims against our subsidiaries and former subsidiaries arising out of, resulting from or attributable to their operations, and the implementation of related releases and indemnification provisions protecting those subsidiaries and their affiliates from future liability for such claims. Although we are not aware of any significant, unresolved claims against our subsidiaries and former subsidiaries that are not subject to the channeling injunction and that relate to the periods during which such excess insurance coverage related, with the contribution of these insurance rights to the asbestos personal injury trust, it is possible that we could have underinsured or uninsured exposure for non-derivative asbestos claims or other personal injury or other claims that would have been insured under these coverages had the insurance rights not been contributed to the asbestos personal injury trust. In conjunction with the spin-off of our former Power Generation business, claims and liabilities associated with these asbestos personal injury, property damage and indirect property damage claims have been expressly assumed by BWE pursuant to the master separation agreement between us and BWE.

NOTE 13 – FINANCIAL INSTRUMENTS WITH CONCENTRATIONS OF CREDIT RISK

The primary customer of our Nuclear Operations and Technical Services segments is the U.S. Government, including some of its contractors. Our Nuclear Energy segment’s major customers are large utilities. These concentrations of customers may impact our overall exposure to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic or other conditions. In the years ended December 31, 2016, 2015 and 2014, U.S. Government contracts accounted for approximately 87%, 88% and 88% of our total consolidated revenues, respectively. Accounts receivable due directly or indirectly from the U.S. Government represented 82% and 77% of net receivables at December 31, 2016 and December 31, 2015, respectively. See Note 17 for additional information about our operations in different geographic areas.

We believe that our provision for possible losses on uncollectible accounts receivable is adequate for our credit loss exposure. At December 31, 2016 and 2015, the allowance for possible losses that we deducted from accounts receivable – trade on the accompanying consolidated balance sheets was $0.0 million.

NOTE 15 – DERIVATIVE FINANCIAL INSTRUMENTS

We have designated all of our FX forward contracts that qualify for hedge accounting as cash flow hedges. The hedged risk is the risk of changes in functional-currency-equivalent cash flows attributable to changes in FX spot rates of forecasted transactions related to long-term contracts. We exclude from our assessment of effectiveness the portion of the fair value of the FX forward contracts attributable to the difference between FX spot rates and FX forward rates. At December 31, 2016, we had deferred approximately $0.3 million of net losses on these derivative financial instruments in accumulated other comprehensive income. Assuming market conditions continue, we expect to recognize substantially all of this amount in the next twelve months.

At December 31, 2016, our derivative financial instruments consisted of FX forward contracts. The notional value of our FX forward contracts totaled $30.8 million at December 31, 2016, with maturities extending to June 2017. These instruments consist primarily of contracts to purchase or sell Canadian Dollars. We are exposed to credit-related losses in the event of nonperformance by counterparties to derivative financial instruments. We attempt to mitigate this risk by using major financial institutions with high credit ratings. The counterparties to all of our FX forward contracts are financial institutions included in our credit facility. Our hedge counterparties have the benefit of the same collateral arrangements and covenants as described under our credit facility.

NOTE 16 – FAIR VALUE MEASUREMENTS

FASB Topic Fair Value Measurements and Disclosures defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. This topic also sets forth the disclosure requirements regarding fair value and establishes a hierarchy for valuation inputs that emphasizes the use of observable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy established by this topic is as follows:


•	Level 1 – inputs are based upon quoted prices for identical instruments traded in active markets.


•	Level 2 – inputs are based upon quoted prices for similar instruments in active markets, quoted prices for similar or identical instruments in inactive markets and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets and liabilities.


•	Level 3 – inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar valuation techniques.

The following sections describe the valuation methodologies we use to measure the fair values of our investments, derivatives and nonrecurring fair value measurements.

Investments

Investments primarily include U.S. Government and agency securities, money-market funds, mortgage-backed securities, corporate bonds and equities.

Table of Contents

In general, and where applicable, we principally use a composite of observable prices and quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing methodology applies to our Level 1 and Level 2 investments.

Centrus Energy Corp. Transaction

On September 5, 2014, the Bankruptcy Court for the District of Delaware approved and confirmed the proposed voluntary Chapter 11 pre-packaged or pre-arranged plan of reorganization of USEC Inc. (the "Plan"). USEC Inc. completed the final steps necessary to emerge from its Chapter 11 bankruptcy on September 30, 2014. The reorganized company is called Centrus Energy Corp. ("Centrus") and trades on the New York Stock Exchange under the trading symbol LEU. Under the Plan, BWXT received 7.98% of the Centrus common stock and approximately $20.2 million in principal amount of 8.0% PIK Toggle Notes due 2019/2024 in exchange for its investment in USEC Series B-1 12.75% Convertible Preferred Stock and Warrants that we wrote off through impairments of $19.1 million and $27.0 million in the years ended December 31, 2013 and 2012, respectively. We recorded a gain in other income of $18.6 million in the third quarter of 2014 for the fair value of the Centrus common stock and notes, which were trading at a discount to par value. We recognized other than temporary impairments of $2.1 million and $4.2 million on our Centrus common stock in the years ended December 31, 2015 and 2014, respectively, due to the severity of its decline in market value since its emergence from bankruptcy.

market-based observable inputs, including FX forward and spot rates, interest rates and counterparty performance risk adjustments. At December 31, 2016 and 2015, we had forward contracts outstanding to purchase or sell foreign currencies, primarily Canadian Dollars, with a total fair value of $(0.4) million and $(3.9) million, respectively.

Other Financial Instruments

We used the following methods and assumptions in estimating our fair value disclosures for our other financial instruments, as follows:

Cash and cash equivalents and restricted cash and cash equivalents. The carrying amounts that we have reported in the accompanying consolidated balance sheets for cash and cash equivalents and restricted cash and cash equivalents approximate their fair values due to their highly liquid nature.

Long-term and short-term debt. We base the fair values of debt instruments on quoted market prices. Where quoted prices are not available, we base the fair values on the present value of future cash flows discounted at estimated borrowing rates for similar debt instruments or on estimated prices based on current yields for debt issues of similar quality and terms. The fair value of our debt instruments approximated their carrying value at December 31, 2016 and December 31, 2015.

NOTE 17 – SEGMENT REPORTING

Our reportable segments are Nuclear Operations, Technical Services and Nuclear Energy, as described in Note 1.

The operations of our segments are managed separately and each has unique technology, services and customer class. We account for intersegment sales at prices that we generally establish by reference to similar transactions with unaffiliated customers. Reportable segments are measured based on operating income exclusive of general corporate expenses, income related to litigation proceeds, gains (losses) on sales of corporate assets, special charges for restructuring activities, mark to market charges related to our pension and postretirement benefit plans and the costs incurred to spin-off our former Power Generation business.

Table of Contents

Income from continuing operations for our March 31, 2015 and June 30, 2015 quarters included costs to spin-off our former Power Generation business of $1.5 million and $24.5 million, respectively. Our September 30, 2015 quarter included income related to litigation proceeds of $94.8 million, inclusive of pre- and post-judgment interest of $29.1 million.

We immediately recognize actuarial gains (losses) for our pension and postretirement benefit plans into earnings in the fourth quarter of each year as a component of net periodic benefit cost. The effect of this adjustment, recorded in the quarters ended December 31, 2016 and 2015 on pre-tax income was $(21.3) million and $(52.5) million, respectively. Additionally, in the quarter ended June 30, 2015, we recognized approximately $(2.2) million in pre-tax expense because of the interim remeasurement requirements resulting from settlements of certain Canadian pension obligations.

Item 9A.	CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As of the end of the period covered by this annual report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) adopted by the SEC under the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Our disclosure controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. You should note that the design of any system of disclosure controls and procedures is based in part upon various assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. Based on the evaluation referred to above, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures are effective as of December 31, 2016 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and such information is accumulated and communicated to management, including its principal executives and principal financial officers or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as that term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) and for our assessment of the effectiveness of internal control over financial reporting.

Our internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of our consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and Board of Directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, including our Chief Executive Officer and Chief Financial Officer, has conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2016, based on the framework established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We have excluded from our assessment the internal control over financial reporting at BWXT Nuclear Energy Canada Inc., which was acquired on December 16, 2016, and whose financial statements constitute 10% and less than 1% of the total assets and revenues, respectively, of our consolidated financial statement amounts as of and for the year ended December 31, 2016. This assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of those controls. Based on our assessment under the criteria described above, management has concluded that our internal control over financial reporting was effective as of December 31, 2016. Deloitte & Touche LLP has audited our internal control over financial reporting as of December 31, 2016, and their report is included in Item 9A.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended December 31, 2016 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of BWX Technologies, Inc.:

We have audited the internal control over financial reporting of BWX Technologies, Inc. and subsidiaries (the "Company") as of December 31, 2016, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management’s Report on Internal Control Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at BWXT Nuclear Energy Canada Inc., which was acquired on December 16, 2016, and whose financial statements constitute 10% and less than 1% of the total assets and revenues, respectively, of the consolidated financial statement amounts as of and for the year ended December 31, 2016. This assessment included an evaluation of the design of the internal control over financial reporting and testing of the operational effectiveness of those controls. Accordingly, our audit did not include the internal control over financial reporting at BWXT Nuclear Energy Canada Inc. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2016 of the Company and our report dated February 27, 2017 expressed an unqualified opinion on those financial statements.
