PART I

Item 1. Business

Overview and History

On Assignment, Inc. (NYSE: ASGN), is a leading global provider of highly skilled, hard-to-find professionals in the growing technology, life sciences, digital and creative sectors, where quality people are the key to success. We go beyond matching résumés with job descriptions, to match people we know into positions we understand, for contract, contract-to-hire and direct hire assignments.

We were incorporated in 1985 and commenced operation of our first contract staffing line of business, which is now our Apex Life Sciences, LLC subsidiary (“Apex Life Sciences”). Expansion into other professional staffing markets has been achieved through acquisitions and internal growth. The following is a summary of significant acquisitions in the past five years:


•	On June 5, 2015, we acquired the holding company of Creative Circle, LLC (“Creative Circle”). Creative Circle, which is headquartered in Los Angeles, California, was purchased to expand our digital and creative staffing services. Creative Circle is included in the Apex operating segment.


•	On December 5, 2013, we acquired the holding company of CyberCoders, Inc. (“CyberCoders”), a privately-owned provider of permanent placement services headquartered in Irvine, California. CyberCoders is included in the Oxford operating segment.


•	On May 15, 2012, we acquired Apex Systems, LLC (“Apex Systems”), a privately-owned provider of information technology staffing and services headquartered in Richmond, Virginia. Apex Systems is in the Apex operating segment.

Significant divestitures in the past five years include the sale of our Physician segment on February 1, 2015, and the sale of our Nurse Travel and Allied Healthcare divisions in 2013. In this 2016 10-K, these businesses are presented as discontinued operations in our consolidated statements of operations and comprehensive income for all periods presented.

Financial information regarding our operating segments and our domestic and international revenues is included under “Financial Statements and Supplementary Data” in Part II, Item 8 of this 2016 10-K.

Our principal office is located at 26745 Malibu Hills Road, Calabasas, California 91301 and our telephone number is (818) 878-7900. We have approximately 158 branch offices within the United States and in seven foreign countries.

Industry and Market Dynamics

The U.S. Bureau of Labor Statistics (“BLS”) updates their employment estimates every two years, and based on their most recent December 2015 projections, they estimate total U.S. employment will grow by 9.8 million jobs, or 6.5 percent, between 2014 and 2024. By comparison, under the previous estimate for 2012 to 2022, BLS projected total employment would grow by 15.6 million jobs, or 11.0 percent. The decrease in projected growth from the prior period is primarily due to the aging of the U.S. population and more people retiring, resulting in a decrease in the labor force participation rate and growth rate.

In their September 2016 U.S. Staffing Industry Forecast report, Staffing Industry Analysts (“SIA”) estimated total U.S. staffing industry revenues were $133.4 billion in 2015 and were projected to be $139.0 billion in 2016 and $144.9 billion in 2017. The largest industry segment, temporary staffing, is forecast to grow at an annual rate of four percent in 2017 with revenues of $124.8 billion, while permanent placement is forecast to grow six percent in 2017 with revenues of $20.1 billion. Within the temporary segment, professional staffing is expected to grow at an annual rate of six percent in 2017 with revenues of $72.3 billion. The temporary staffing industry is historically cyclical and typically has a strong correlation to employment and gross domestic product (“GDP”) growth.

Specific to the professional temporary staffing markets where On Assignment’s businesses are concentrated, the SIA report projects the U.S. information technology (“IT”) temporary staffing market will increase six percent, marketing/creative will increase seven percent, engineering/design will increase one percent and clinical/scientific will increase five percent in 2017.

We anticipate clients for our technology, digital, life sciences and creative staffing services will increase their use of contract labor through professional staffing firms to meet the need for increases in capacity of their workforce. By using outsourced labor, these clients will benefit from cost structure advantages, improved flexibility to address fluctuating demand in business and access to greater expertise.

Clients

We serve our clients by effectively understanding their staffing needs and providing them qualified professionals with the unique combination of skills, experience and expertise to meet those needs. We believe effective engagements of contract technology, digital, life sciences and creative professionals require the people involved in making assignments to have significant knowledge of the client’s industry and the ability to assess the specific needs of the client as well as the contract professionals’ qualifications. During the year ended December 31, 2016, we provided contract professionals to approximately 14,000 clients. In 2016, no single client represented more than seven percent of our revenues.

When clients use independent contractors, they face the potential risk of worker misclassification and resulting liability of federal and state taxes, wage and hour, immigration, diversity, employee rights and other laws and regulations. That risk can be significantly mitigated and clients can stay compliant with ever-changing employment laws and regulations by working with a reputable staffing firm like On Assignment.

Our clients set rigorous requirements for the talent they are seeking, and we use our extensive databases and deep relationships with our contract professionals to quickly identify and pre-screen candidates whose qualifications meet those requirements. We are responsible for recruiting, verifying credentials upon request, hiring, administering pay and benefits, compliance and training as applicable. Clients select the candidate and control and direct the work of contract professionals and approve hours worked. Once on their assignment, contract professionals are generally our employees, although clients provide on-the-job supervision of these professionals.

Candidates

The candidates we recruit are technical, scientific, digital and creative professionals looking for either contract work or permanent placement opportunities.

Hourly wage or contract rates for our contract professionals are established based on their specific skills and whether or not the assignment involves travel away from their primary residence. For our contract employees, we pay the related costs of employment including social security taxes, federal and state unemployment taxes, workers’ compensation insurance and other similar costs. After achieving minimum service periods and/or hours worked, our contract employees are offered access to medical and other voluntary benefit programs (e.g., dental, vision, disability) and the right to participate in our 401(k) Retirement Savings Plan. Each contract professional’s employment relationship with us is terminable at will.

Professionals looking for a permanent placement may apply directly for open positions within a company or partner with a staffing agency to ensure they receive the best opportunities available in their industry. Candidates may work with one or more staffing companies during this process and often develop long-term relationships with their recruiter for future career advancement. Once placed in a permanent position, the professional is paid and receives benefits directly through the employer.

Strategy

On Assignment’s strategy is to identify, enter and be a dominant player in the most attractive segments of the professional staffing market through acquisition, organic growth and effective execution. Our financial goals are to grow our business to $3.0 billion in revenues by 2018 while maintaining attractive margins and earnings per share (“EPS”) growth. To achieve these goals we will continue our specialization in the large and growing technology, life sciences, digital and creative segments of the professional staffing market; reinforce our position as a dominant competitor in each; invest primarily in domestic markets; and pursue further disciplined acquisitions.

Our strategic innovation efforts and technology investments focus on putting the best productivity tools in the hands of our Account Executives and Recruiters, and we continue delivering world class services that make working with On Assignment easy for our clients. We continually respond to emerging trends in digitization, technology and candidate sourcing by using technology to better position our businesses and improve how we serve clients and consultants.

We consolidate our corporate support services - finance, accounting, human resources, legal, marketing and IT - in centralized locations where we can most effectively and efficiently perform these functions, allowing us to leverage our fixed costs and generate higher incremental earnings as our revenues grow. In addition, we invest in leasehold improvements as we expand, relocate and rationalize our branch facilities to increase the productivity of our staffing consultants.

In 2016, we continued to focus on increasing market share in each of our businesses, expanding our service offerings and controlling our operating costs. We also substantially added to the number of staffing consultants we employed. Over the course of the year, the average number of recruiters and sales personnel we employed increased 13 percent.

Competition

We compete with other large publicly-held and privately-owned staffing companies on an international, national, regional and local basis. Each of our businesses has unique competitors, and further details are provided within the Operating Segments section below.

The principal competitive factors in attracting qualified candidates for temporary employment or permanent placements are contract rates, salaries and benefits; availability and variety of opportunities; quality, duration and location of assignments; and responsiveness to requests for placement. Many people seeking temporary employment or permanent placements through us are also pursuing employment through other means, including other staffing agencies. Therefore, the speed at which we assign prospective professionals and the availability of attractive and appropriate assignments are important factors in our ability to fill open positions. In addition to having high quality candidates to assign in a timely manner, the principal competitive factors in obtaining and retaining clients in the staffing industry are properly assessing the clients’ specific job requirements, the appropriateness of the professional assigned to the client, the price of services and monitoring our clients’ satisfaction. Although we believe we compete favorably with respect to these factors, we expect competition to continue to increase.

Trade names

On Assignment maintains registered trademarks, trade names and service marks in the United States, Canada, the European Community and various other countries. The current marks and trade names we have registered include On Assignment®, Apex Systems®, Creative Circle®, CyberCoders®, Lab Support®, LabResource®, Oxford Global Resources®, Oxford International®, Oxford Healthcare IT®, Valesta®, The Right Talent.

Creative Circle

Oxford Segment

The Oxford Segment provides specialized staffing, permanent placement and consulting services in select skill and geographic markets. Our businesses in this segment include Oxford Global Resources, LLC (“Oxford”), CyberCoders and Life Sciences Europe. Segment revenues for 2016 were $603.9 million and represented 24.7 percent of our total revenues.

Oxford Global Resources

Oxford specializes in recruiting and delivering experienced IT, engineering and regulatory and compliance consultants to clients for temporary assignments. These consultants typically have a great deal of knowledge and experience in specialized technical fields which make them uniquely qualified to fill a given assignment. Our competitive advantage comes from our recruiting-driven business process that results in our ability to respond very quickly with high quality candidates to a client's request, thus Oxford's tagline “The Right Talent. Right Now®.” Demand for Oxford's services is driven by a shortage of experienced consultants with specialized technical skills that organizations need quickly but cannot find on their own. Additionally, the push for adoption of health information technology, compliance with FDA regulations and increasing digitization of business processes is accelerating the demand for services. Our services are provided to clients in a wide range of industries and range from large companies that may, for example, be installing new enterprise-wide computer systems and have a need for a subject matter expert with a specific technical and industry-specific experience, to small and mid-sized companies, such as a medical device manufacturer who needs a specialized hardware engineer. Assignments for Oxford typically vary from two to eight months.

Oxford's sales and recruiting activities are delivered through eight recruiting centers across the United States and two in Europe, along with 16 local offices serving major metropolitan markets in the United States. Corporate support activities for Oxford are based in Beverly, Massachusetts, Calabasas, California and Cork, Ireland. Oxford’s competition varies across their service lines, and includes local, regional and national specialty staffing companies as well as small boutique and large international IT and engineering consulting firms. Examples of Oxford competitors include Accenture PLC, Cap Gemini S.A., Robert Half Technology (Robert Half International Inc.), Validant (Kinsale Holdings, Inc.), Nordic Consulting Partners, Inc. and K2 Partnering Solutions, Inc.

CyberCoders

CyberCoders specializes in recruiting professionals for permanent placements in engineering, technology, sales, executive, financial, accounting, scientific, legal and operations positions. CyberCoders’ proprietary software and unique matching algorithm combine to deliver an impressive turnaround time for employers and help candidates find jobs that truly fit their background and career goals. Our permanent placements are typically subject to a contingency period; if the candidate leaves the client during the contingency period, we will find a replacement at no cost to the client. Although the contingency period can vary by contract, it is typically 90 days or less. CyberCoders is based in Irvine, California, with corporate support activities in Beverly, Massachusetts and sales and recruiting operating from three hub locations in the United States. Other companies that have large permanent placement divisions include Robert Half, Management Recruiters International, Inc., Allegis, Randstad and Adecco.

Life Sciences Europe

Life Sciences Europe includes the brands Lab Support, LabResource and Valesta, which provide locally-based contract and permanent life science professionals to clients with research and development projects in the biotechnology, pharmaceutical, food and beverage, personal care, chemical, medical device, automotive, municipal, education and environmental industries. Assignments for Life Sciences Europe typically vary from five to 18 months, although they can be longer. Life Sciences Europe sales and recruiting services are delivered in nine local branch offices in the United Kingdom, the Netherlands, Belgium and Spain and the corporate services are based in Cork, Ireland. Competitors include Hays Life Sciences (Korn/Ferry International), Randstad Life Sciences (Randstad) and Science Recruitment Group Ltd.

Employees

At December 31, 2016, we employed approximately 3,620 internal employees, including staffing consultants, regional sales directors, account managers, recruiters and corporate office employees. Throughout 2016 we placed approximately 52,260 contract professionals who are our employees on assignments with clients. Those assignments varied in length as described in the Operating Segments discussion above.

Government Regulation

We take reasonable steps to ensure that our contract professionals possess all current licenses and certifications required for each placement. We provide state mandated workers’ compensation insurance, unemployment insurance and professional liability insurance for our internal employees and our contract professionals who are our employees. These expenses have a direct effect on our costs of services, margins and likelihood of achieving or maintaining profitability.

Item 1A. Risk Factors

Our business is subject to a number of risks including, but not limited to, the following:

U.S. and global market and economic developments could adversely affect our business, financial condition and results of operations.

In the past few years, global macroeconomic conditions and trends have been uncertain and difficult to predict, particularly within the United States and Europe, which have experienced a period of slow growth and recession, respectively. Demand for our staffing services is significantly affected by the general level of economic activity and employment in the United States and Europe. As economic activity slows, companies may defer projects for which they utilize our services or reduce their use of temporary employees before laying off full-time employees. We may also experience more competitive pricing pressure during periods of economic downturn. Approximately 95 percent of our revenues in 2016 were generated by our business operations in the United States. Any significant economic downturn in the United States or other countries in which we operate could have a material adverse effect on our business, financial condition and results of operations.

Demand for the contract staffing services that we provide is significantly affected by global market and economic conditions. As economic activity slows, particularly any negative effect on research and development, quality control and capital spending, many clients or potential clients reduce their use of and reliance upon contract professionals. During periods of reduced economic activity, we may also be subject to increased competition for market share and pricing pressure. As a result, a recession or periods of reduced economic activity could harm our business and results of operations.

If we are not able to remain competitive in obtaining and retaining temporary staffing clients, our future growth will suffer. Agreements may be terminated by clients and contract professionals at will and the termination of a significant number of such agreements would adversely affect our revenues and results of operations.

The contract staffing industry is highly competitive and fragmented with limited barriers to entry. We compete in national, regional and local markets with full-service agencies, and in regional and local markets with specialized contract staffing agencies. The success of our business depends upon our ability to continually secure new orders from clients and to fill those orders with our contract professionals.

Our agreements with clients do not provide for exclusive use of our services and in some instances we provide services without entering into contracts. As such, clients are free to place orders with our competitors. Each contract professional’s employment with us is terminable at will. All contract assignments, regardless of their planned length, may be terminated with limited notice by the client or the contract professional. The duration of agreements with clients are generally dictated by the contract. Usually, contracts with clients may be terminated with 30 days’ notice by us or by the clients and, oftentimes, assignments may be terminated with less than one week’s notice. If clients terminate a significant number of our staffing agreements or assignments and we are unable to generate new contract staffing orders to replace lost revenues, or a significant number of our contract professionals terminate their employment with us and we are unable to find suitable replacements, the growth of our business could be adversely affected and our revenues and results of operations could be harmed. As a result, it is imperative to our business that we maintain positive relationships with our clients and contract professionals.

To the extent that competitors seek to gain or retain market share by reducing prices or increasing marketing expenditures, we could lose revenues and our margins could decline, which could harm our operating results and cause the trading price of our stock to decline. As we expand into new geographic markets, our success will depend in part on our ability to gain market share from competitors. We also may face potential competition from technology companies that currently offer job- and resume-posting services to the extent these companies are developing and adopting technologies and strategies that allow them to compete in the staffing industry. We expect competition for clients to increase in the future, and the success and growth of our business depends on our ability to remain competitive. In addition, we participate in a number of third

party contracts as a subcontractor, and that requires us to participate in vendor management contracts, which may subject us to greater risks or lower margins.

If we are unable to meet our expectations for growth, our future results of operations are likely to be adversely affected.

Over the past several years, we have experienced revenue and earnings growth. Our five-year business strategy includes the expectation of future internal growth supplemented by acquisitions to attain $3 billion in annual revenues by 2018. There is no assurance that we will be able to continue this pace of growth in the future or meet our strategic objectives for growth. Our growth could be negatively affected by many factors, including future technology industry conditions, macroeconomic events, competition and labor market trends or regulations. If our growth rate slows, or if it fails to grow at the pace anticipated, and we are unable to be successful in our growth initiatives and strategies, our financial results are likely to be adversely affected and could be less than our expectations or those of investors or analysts.

Our business strategy also includes continuing efforts to integrate and optimize our organization, programs, technology and delivery of services to make us a more agile and effective competitor, to reduce the cost of operating our business and to increase our operating profit and operating profit margin. We may not be successful in our continuing integration and optimization efforts, and they may fail to achieve the cost savings we anticipate. Further, we may fail to prevent the return of costs eliminated in these efforts. If we are not successful in implementing our integration and optimization efforts, our business, financial condition and results of operations could be materially adversely affected.

If we are unable to attract and retain qualified contract professionals, our business could be negatively impacted.

Our business is substantially dependent upon our ability to attract and retain contract professionals who possess the skills, experience and licenses, as required, to meet the specified requirements of our clients. We compete for such contract professionals with other temporary staffing companies and with our clients and potential clients. There can be no assurance that qualified professionals will be available to us in adequate numbers to staff our temporary assignments. Moreover, our contract professionals are often hired to become regular employees of our clients. Attracting and retaining contract professionals depends on several factors, including our ability to provide contract professionals with desirable assignments and competitive wages and benefits. The cost of attracting and retaining contract professionals in the future may be higher than we anticipate if there is an increase in competitive wages and benefits and, as a result, if we are unable to pass these costs on to our clients, our likelihood of achieving or maintaining profitability could decline. In periods of high unemployment, contract professionals frequently opt for full-time employment directly with clients and, due to a large pool of available candidates, clients are able to directly hire and recruit qualified candidates without the involvement of staffing agencies. If we are unable to attract and retain a sufficient number of contract professionals to meet client demand, we may be required to forgo staffing and revenue opportunities, which may hurt the growth of our business.

Our results of operations could be negatively affected if we cannot successfully keep pace with technological changes in the development and implementation of our services.

Our success depends on our ability to keep pace with rapid technological changes in the development and implementation of services. We rely on a variety of technologies to support important functions in our business, including the recruitment, placement and monitoring of our contract professionals; billing; and client data analytics. If we do not sufficiently invest in new technology and industry developments, appropriately implement new technologies, or evolve our business at sufficient speed and scale in response to such developments, or if we do not make the right strategic investments to respond to these developments, our services, results of operations, and ability to develop and maintain our business could be negatively affected.

Reclassification of our independent contractors by tax or regulatory authorities could materially and adversely affect our business model and could require us to pay significant retroactive wages, taxes and penalties.

We may place individuals who work for their own corporations to provide services in connection with our business as independent contractors rather than employees. As such, we do not withhold or pay income or other employment related taxes, or provide workers’ compensation insurance for them. We believe that our classification of those individuals or their corporations as independent contractors is consistent with general industry standard and applicable guidelines from the U.S. Department of Labor and the Internal Revenue Service, but can nonetheless be challenged by the contractors themselves or by relevant taxing authorities. If federal or state taxing authorities determine that individuals employed by their own corporations engaged as independent contractors are employees, our business model could be adversely affected.

Our business is subject to government regulation, which in the future could restrict the types of employment services we are permitted to offer or result in additional or increased costs that reduce our revenues and earnings.

The temporary staffing services industry is regulated in the United States and other countries in which we operate. In most countries, including the United States where most of our business is conducted, we are considered the legal employer of our temporary personnel. Therefore, we are subject to federal, state and local laws and regulations governing the employer/employee relationship, such as those related to payment of federal, state and local payroll and unemployment taxes for our corporate employees and contractor professional employees, tax withholding, social security or retirement benefits, licensing, wage and hour requirements, paid sick leave and other leaves, employee benefits, pay equity, non-discrimination, sexual harassment, workers’ compensation, compliance with immigration laws and a wide variety of notice and administrative requirements, such as record keeping, written contracts and reporting. We are also subject to U.S. laws and regulations relating to government contracts with federal agencies. In other countries, while we may not be considered the legal employers of our temporary personnel, we are still responsible for collecting taxes and social security deductions and transmitting these amounts to the taxing authorities.

Future changes in the laws or governmental regulations affecting our business may result in the prohibition or restriction of certain types of employment services that we are permitted to offer or the imposition of new or additional legal requirements that could increase our costs and reduce our revenues and earnings. Due to the substantial number of state and local jurisdictions in which we operate, there also is a risk that we may be unaware of, or unable to adequately monitor, actual or proposed changes in, or the interpretation of, the laws or governmental regulations of such states and localities. Any delay in our compliance with changes in such laws or governmental regulations could result in potential fines, penalties, or other sanctions for non-compliance.

In addition, the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (collectively, the “ACA”), which enacted comprehensive healthcare reform legislation in the United States, requires that we provide healthcare coverage to our eligible employees and temporary contract professionals in the United States or potentially pay a penalty. Although we believe we have properly identified eligible employees, a later determination that we failed to offer the required health coverage to eligible employees could result in penalties that may materially harm our business.

Any future changes in laws or government regulations applicable to our business may make it more difficult and expensive to provide staffing services and could have a material adverse effect on our business, financial condition and results of operations. Although we may elect to bill some or all of any additional costs to our customers, there can be no assurances that we will be able to increase the fees charged to our customers in a timely manner and in a sufficient amount to fully cover any increased costs as a result of future changes in laws or government regulations.

Significant legal actions and claims could subject us to substantial uninsured liabilities, result in damage to our business reputation, result in the discontinuation of our client relationships and adversely affect our recruitment and retention efforts.

We employ people internally and in the workplaces of other businesses. Our ability to control the workplace environment of our clients is limited. Further, many of the individuals that we place with our clients have access to client information systems and confidential information. As the employer of record of our contract professionals, we incur a risk of liability to our contract professionals for various workplace events, including claims of physical injury, discrimination, harassment or failure to protect confidential personal information. Other inherent risks include possible claims of errors and omissions; intentional misconduct; release, misuse or misappropriation of client intellectual property; employment of illegal aliens; criminal activity; torts; or other claims. We also have been subject to legal actions alleging vicarious liability, intentional torts, negligent hiring, discrimination, sexual harassment, retroactive entitlement to employee benefits, violation of wage and hour requirements and related legal theories. These types of actions could involve large claims and significant defense costs. We may be subject to liability in such cases even if the contribution to the alleged injury was minimal.

A failure of any of our employees internally or contract professionals in the workplace to observe our policies and guidelines intended to reduce these risks could result in negative publicity, injunctive relief, criminal investigations and/or charges, payment of monetary damages or fines, or other material adverse effects on our business. Claims raised by clients stemming from the improper actions of our contract professionals, even if without merit, could cause us to incur significant expense associated with the costs or damages related to such claims. Further, such claims by clients could damage our business reputation and result in the discontinuation of client relationships. Any associated negative publicity could adversely affect our ability to attract and retain qualified contract professionals in the future.

In most instances, we are required to indemnify clients against some or all of these risks, and we could be required to pay substantial sums to fulfill our indemnification obligations. In addition, certain of our clients currently require, and other clients in the future may require, that we indemnify them against losses in the event that the client is determined to be non-compliant with the ACA with respect to one or more of our temporary contract professionals assigned to such client. Although we believe that we are currently in compliance with the requirements of the ACA and we have not received notice from any client that acts or omissions by us may have resulted in losses to the client relating to non-compliance with the ACA, any future liabilities that may be incurred by us pursuant to such indemnification provisions could adversely affect our results of operations.

To protect ourselves from the costs and damages of significant legal actions and claims, we maintain workers’ compensation, errors and omissions, employment practices and general liability insurance coverage in amounts and with deductibles that we believe are appropriate for our operations. Our coverage includes a retention amount, and our insurance coverage may not cover all claims against us or continue to be available to us at a reasonable cost. In addition, we face various employment-related risks not covered by insurance, such as wage and hour laws and employment tax responsibility. If we do not maintain adequate insurance coverage or are made party to significant uninsured claims, we may be exposed to substantial liabilities that could have a material adverse effect on our results of operations and financial condition.

A loss or reduction in revenues from one or more large client accounts could have a material adverse effect on our business.

Our clients range in size from large national or multinational companies to small and mid-market businesses. Our ten largest clients represented approximately 18 percent of our revenues and no single client accounted for more than seven percent of our total revenues in 2016. Our large clients may enter into non-exclusive arrangements with several staffing firms, and the client is generally able to terminate our contracts on short notice without penalty. The deterioration of the financial condition or business prospects of these large clients, or a change in their strategy around the use of our services, could reduce their need for our services and result in a significant decrease in the revenues and earnings we derive from them. The loss of one or more of our large national or multinational clients or a significant decrease in their demand for our services could have a material adverse effect on our results of operations.

Significant developments arising from the 2016 U.S. federal elections or the United Kingdom’s referendum on membership in the European Union (“EU”) could have a material adverse effect on us.

In January 2017, a new president and Congress took office in the United States proposing various changes to U.S. laws, regulations and policies. These proposals include, among other things, changes to existing immigration and trade policies, corporate tax reform and a commitment to repeal and replace the ACA. Such proposals have created uncertainty surrounding potential changes to U.S. laws, regulations and policies and the impact of any such changes on future economic conditions in the United States. Any significant changes in U.S. laws, regulations and policies governing immigration, trade, corporate taxes, health care or other matters that increase our costs or make it more difficult to provide our services could have a material adverse effect our business.

In addition, in June 2016, the United Kingdom held a referendum and voted in favor of leaving the EU, which has created political and economic uncertainty in the United Kingdom and the EU. The United Kingdom’s withdrawal from the EU could cause a slowdown in economic activity in the United Kingdom, Europe or globally, which could adversely affect our business.

We may not successfully make or integrate acquisitions, which could harm our business and growth.

As part of our growth strategy, we intend to opportunistically pursue selected acquisitions. We compete with other companies in the professional staffing and consulting industries for acquisition opportunities, and there can be no assurance that we will be able to successfully identify suitable acquisition candidates or be able to complete future acquisitions on favorable terms, if at all. There also can be no assurance that we will realize the benefits expected from any transaction or receive a favorable return on investment from our acquisitions.

We may pay substantial amounts of cash or incur debt to finance our acquisitions, which could adversely affect our liquidity and capital resources. The incurrence of indebtedness would also result in increased interest expense, and could also include covenants or other restrictions that would impede our ability to manage our operations. We may also issue equity securities to pay for acquisitions, which could result in dilution to our stockholders. In addition, any acquisitions we announce could be viewed negatively by investors, which may adversely affect the price of our common stock.

The integration of an acquisition involves a number of factors that may affect our operations. These factors include diversion of management’s attention from other business concerns, difficulties or delay in the integration of acquired operations, retention of key personnel, entry into unfamiliar markets, significant unanticipated costs or legal liabilities and tax and accounting issues. If we fail to accurately forecast the financial impact of an acquisition transaction, we may incur tax and accounting changes. Furthermore, once we have integrated an acquired business, the business may not achieve anticipated levels of revenue, profitability, or productivity, or otherwise perform as expected. Any of these factors may have a material adverse effect on our results of operations and financial condition.

The loss of key members of our senior management team could adversely affect the execution of our business strategy and our financial results.

We believe that the successful execution of our business strategy and our ability to build upon our business and acquisitions of new businesses depends on the continued employment of key members of our senior management team. We have provided short- and long-term incentive compensation to our key management in an effort to retain them. However, if members of our senior management team become unable or unwilling to continue in their present positions, we could incur significant costs and experience business disruption related to time spent on efforts to replace them and our financial results and our business could be materially adversely affected.

Impairment of goodwill or identifiable intangible assets could materially impact future results of operations.

We had approximately $873.5 million in goodwill and $377.7 million in identifiable intangible assets at December 31, 2016. As part of the testing of goodwill impairment, Accounting Standards Codification Topic 350, Intangibles - Goodwill and Other, requires us to estimate the fair value of our reporting units on at least an annual basis and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The impairment tests consist of comparing the fair value of a reporting unit with its carrying amount, including goodwill. We determine the fair value of each reporting unit based upon a weighted average calculation using the fair value derived from a discounted cash flow analysis, a guideline company market approach and a similar transactions market approach. Discounted cash flows are developed for each reporting unit based on assumptions including revenue growth expectations, gross margins, operating expense projections, working capital, capital expense requirements and tax rates. The multi-year financial forecasts for each reporting unit used in the cash flow models considered several key business drivers such as new product lines, historical performance and industry and economic trends, among other considerations. The market approach considers multiple financial metrics, primarily earnings before interest, taxes, depreciation and amortization (“EBITDA”), based on trading multiples of a group of guideline public companies in the staffing industry, which multiples are then applied to the corresponding financial metrics of our reporting units to derive an indication of fair value. The similar transaction method considers multiple financial metrics, primarily EBITDA, based on trading multiples of actual transactions that have occurred, which multiples are then applied to the corresponding financial metrics of our reporting units to derive an indication of fair value. There are inherent uncertainties related to the factors, and management's judgment in applying these factors. At October 31, 2016, we performed our annual goodwill impairment test and concluded that there was no impairment. Future declines in our market capitalization or any other impairment indicators subsequent to the balance sheet date could be an early indication that remaining goodwill may become impaired in the future. Although a future impairment of goodwill and indefinite lived identifiable intangible assets would not affect our cash flow, it would negatively impact our operating results.

Intangible assets with indefinite lives consist of trademarks. We test trademarks for impairment on an annual basis, on October 31. In order to test the trademarks for impairment, we determine the fair value of the trademarks and compare such amount to their carrying values. We determine the fair value of the trademarks using a projected discounted cash flow analysis based on the relief-from-royalty approach. The principal factors used in the discounted cash flow analysis requiring judgment are projected net sales, discount rate, royalty rate and terminal value assumption. The royalty rate used in the analysis is based on transactions that have occurred in our industry. Intangible assets having finite lives are amortized over their useful lives and are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Customer relationships are amortized using an accelerated method. Contractor relationships and non-compete agreements are amortized using the straight-line method.

We are subject to business risks associated with international operations, which could make our international operations significantly more costly.

Although we have limited experience in marketing, selling and supporting our services outside of the United States, we had international sales in Canada, the EU and Switzerland in 2016. Our international operations comprised approximately 4.7 percent of total sales in 2016 compared with 4.5 percent in 2015 and 4.7 percent in 2014. We also have offices and employees outside the United States. Our sales and operations outside the United States expose us to currency, operational, regulatory and political risks in the countries in which we operate. For example our exposure to currency risks results in fluctuations in our results of operations. Our management of international operations also results in increased costs. If we are not able to manage these risks, our business and results of operations would adversely affected.

An information technology system failure may adversely affect our business.

In 2016, we continued to upgrade our information technology systems, including our PeopleSoft^TM and other enterprise-wide information systems that are used in daily operations to identify and match staffing resources and client assignments and manage scheduling. We also rely on our information systems in managing our accounting, including our pay and bill functions and financial reporting. If the systems fail or are otherwise unable to function in a manner that properly supports our business operations, or if these systems require significant costs to repair, maintain, or further develop, we could experience business interruptions or delays that could materially and adversely affect our business and financial results. Our information systems are vulnerable to fire, storm, flood, power loss, telecommunications failures, terrorist attacks, physical or software break-ins, viruses, security breaches and similar events. Any system failure or service outage at the facilities where our network infrastructure is located could result in a loss of service for the duration of the failure or the outage. If our primary and backup information systems fail or are otherwise unavailable, these functions would have to be accomplished manually, which could impact our ability to respond to business opportunities quickly, to pay our staff in a timely fashion and to bill for services efficiently.

Our collection, use and retention of personal information and personal health information create risks that may harm our business.

In the ordinary course of our business, we collect and retain personal information of our employees and contract professionals and their dependents including, without limitation, full names, social security numbers, addresses, birth dates and payroll-related information. Our employees may also have access to, receive and use personal health information in the ordinary course of our Health Information Management businesses. We use commercially available information security technologies to protect such information in digital format. We also use security and business controls to limit access to such information. However, employees or third parties may be able to circumvent these measures and acquire or misuse such information, resulting in breaches of privacy and errors in the storage, use or transmission of such information. Privacy breaches may require notification and other remedies, which can be costly, and which may have other serious adverse consequences for our business, including regulatory penalties and fines, claims for breach of contract, claims for damages, adverse publicity, reduced demand for our services by clients and/or consultants, harm to our reputation and regulatory oversight by state or federal agencies.

The possession and use of personal information and data in conducting our business subjects us to legislative and regulatory burdens. We may be required to incur significant expenses to comply with mandatory privacy and security standards and protocols imposed by law, regulation, industry standards, or contractual obligations with our clients.

Cybersecurity risks and cyber incidents could adversely affect our business and disrupt operations.

Cyber incidents can result from deliberate attacks or unintentional events. These incidents can include, but are not limited to, gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may not immediately produce signs of intrusion, we may be unable to anticipate these incidents or techniques, timely discover them, or implement adequate preventative measures. Our information technology may not provide sufficient protection, and as a result we may lose significant information about us or our employees or customers. Other results of these incidents could include, but are not limited to, disrupted operations, liability for stolen assets or the disclosure of personally identifiable information of our employees or employees of our subcontractors, misstated financial data, increased cybersecurity protection costs, litigation and reputational damage adversely affecting customer or investor confidence.

Failure of internal controls may leave us susceptible to errors and fraud.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable assurance that the objectives of the control system are met. Furthermore, because of the inherent limitations in all control systems, no evaluation of controls

can provide absolute assurance that all control issues and instances of fraud, if any, would be detected, particularly in our acquired companies and international operations. If our internal controls are unsuccessful, our business and results of operations could be adversely affected.

As of December 31, 2016, we had $656.0 million of total debt, which could adversely affect our operating flexibility, and the restrictive covenants under our debt instruments could trigger prepayment obligations or additional costs.

Our level of debt and the limitations imposed on us by our credit agreements could have important consequences for investors, including the following:


•	we have to use a portion of our cash flow from operations for debt service rather than for our operations;


•	we may not be able to obtain additional debt financing for future working capital, capital expenditures or other corporate purposes or may have to pay more for such financing;


•	some or all of the debt under our current or future credit facilities may be at a variable interest rate, making us more vulnerable to increases in interest rates;


•	we could be less able to take advantage of significant business opportunities, such as acquisition opportunities and to react to changes in market or industry conditions; and


•	we may be disadvantaged compared to competitors with less leverage.

Our failure to comply with restrictive covenants under our credit facilities and other debt instruments could result in an event of default, which, if not cured or waived, could result in the requirement to repay such borrowings before their due date. Some covenants are tied to our operating results and thus may be breached if we do not perform as expected. Further, the terms of our credit facility permit additional borrowings, subject to certain conditions. If new debt is added to our current debt levels, the related risks we now face could intensify.

We expect to obtain the money to pay our expenses and to repay borrowings under our credit facility primarily from our operations. Our ability to pay our expenses thus depends on our future performance, which will be affected by financial, business, economic and other factors. If we do not have enough money, we may be required to refinance all or part of our existing debt, sell assets or borrow additional funds. We may not be able to take such actions on terms that are favorable to us, if at all. The lenders may require fees and expenses to be paid or other changes to terms in connection with waivers or amendments. If we are forced to refinance these borrowings on less favorable terms, our results of operations and financial condition could be adversely affected by increased costs and/or rates.

The trading price of our common stock has experienced significant fluctuations, which could make it difficult for us to access the public markets for financing or use our common stock as consideration in a strategic transaction.

In 2016, the trading price of our common stock experienced significant fluctuations, ranging from a high of $45.83 to a low of $29.34. The closing price of our common stock on the NYSE was $47.82 on February 23, 2017. Our common stock may continue to fluctuate widely as a result of a large number of factors, many of which are beyond our control, including:


•	period to period fluctuations in our financial results or those of our competitors;


•	failure to meet previously announced guidance or analysts’ expectations of our quarterly results;


•	announcements by us or our competitors of acquisitions, significant contracts, commercial relationships or capital commitments;


•	commencement of, or involvement in, litigation;


•	any major change in our board or management;


•	changes in government regulations;


•	recommendations by securities analysts or changes in earnings estimates;


•	the volume of shares of common stock available for public sale;


•	announcements by our competitors of their earnings that are not in line with analyst expectations;


•	sales of stock by us or by our stockholders;


•	short sales, hedging and other derivative transactions in shares of our common stock; and


•	general economic conditions, slow or negative growth of unrelated markets and other external factors.

Our results of operations may vary from quarter to quarter as a result of a number of factors, including, among other things, the level of demand for our temporary staffing services, changes in our pricing policies or those of our competitors, our ability to control costs and our ability to manage our accounts receivable balances, which may make it difficult to evaluate our business and could cause instability in the trading price of our common stock. In addition, the stock market has experienced extreme price and volume fluctuations that have affected the trading prices of the common stock of many companies involved in the temporary staffing industry. As a result of these fluctuations, we may encounter difficulty should we determine to access the public markets for financing or use our common stock as consideration in a strategic transaction.

A significant loss or suspension of our business with the federal government or government contractors could lead to a material reduction in our revenues, cash flows and operating results.

We contract with and serve the U.S. federal government and its agencies as a prime contractor. We also provide staffing services as a subcontractor to federal prime contractors. In these capacities, we must comply with complex laws and regulations relating to the formation, administration and performance of federal government contracts. These laws and regulations create compliance risk and may impose added costs on our business. If a government review, investigation or audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, harm to our reputation, suspension of payments, fines and

suspension or debarment from doing business with federal government agencies. Revenues from federal government agencies and government contractors were less than five percent of our total revenues in 2016.

There is often intense competition to win federal agency contracts. Even when a contract is awarded to us, competitors may protest such awards. If we are unable to successfully compete for new business or win competitions to maintain existing business, our business could be materially adversely affected. After a government contract is awarded and funded by the federal government, we are dependent upon the ability of the relevant agency to administratively manage the contract. We can be adversely impacted by delays in the start-up of already awarded and funded projects, including delays due to shortages of acquisition and contracting personnel within the federal government agencies.

Some government contracts require us to maintain facility security clearances and require some of our employees to maintain individual security clearances. If our employees lose or are unable to timely obtain security clearances, or we lose a facility clearance, a government agency client may terminate the contract or decide not to renew it upon its expiration. In addition, a security breach by us could cause serious harm to our business, damage our reputation and prevent us from being eligible for further work on sensitive or classified systems for federal government clients.

Provisions in our corporate documents and Delaware law may delay or prevent a change in control that our stockholders consider favorable.

Provisions in our certificate of incorporation and bylaws could have the effect of delaying or preventing a change of control or changes in our management. These provisions include the following:


•	Our Board of Directors has the right to elect directors to fill a vacancy created by the expansion of the Board of Directors up to nine members, or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our Board of Directors.

•

Stockholders must provide advance notice to nominate individuals for election to the Board of Directors or to propose matters that can be acted upon at a stockholders’ meeting. Further, our Board of Directors is divided into three classes, and only one class is up for election each year. These provisions may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

•

Our Board of Directors may issue, without stockholder approval, up to one million shares of undesignated or “blank check” preferred stock. The ability to issue undesignated or “blank check” preferred stock makes it possible for our Board of Directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt or make it more difficult for a third party to acquire us.

As a Delaware corporation, we are also subject to certain Delaware anti-takeover provisions, including Section 203 of the Delaware General Corporation Law. Under these provisions, a corporation may not engage in a business combination with any large stockholders who hold 15 percent or more of our outstanding voting capital stock in a merger or business combination unless the holder has held the stock for three years, the Board of Directors has expressly approved the merger or business transaction, or at least two-thirds of the outstanding voting capital stock not owned by such large stockholder approve the merger or the transaction. These provisions of Delaware law may have the effect of delaying, deferring, or preventing a change of control and may discourage bids for our common stock at a premium over its market price. In addition, our Board of Directors could rely on these provisions of Delaware law to discourage, prevent, or delay an acquisition of us.

Not applicable.

Item 2. Properties

As of December 31, 2016, we leased approximately 37,200 square feet of office space through November 2021 for our corporate headquarters in Calabasas, California. Additionally, we leased approximately 48,600 square feet of office space through December 2025 at our Oxford headquarters in Beverly, Massachusetts; and 55,900 square feet of office space through October 2024 at our Apex headquarters in Richmond, Virginia.

In addition, as of December 31, 2016, we leased approximately 849,100 square feet of total office space in approximately 158 branch office locations in the United States, United Kingdom, Netherlands, Belgium, Ireland, Switzerland, Spain and Canada. A branch office typically occupies space ranging from approximately 1,000 to 32,000 square feet with lease terms that typically range from three months to 11 years. We believe that our facilities are suitable and adequate for our current operations.

Item 3. Legal Proceedings

We are involved in various legal proceedings, claims and litigation arising in the ordinary course of business. However, based on the facts currently available, we do not believe that the disposition of matters that are pending or asserted will have a material effect on our financial position, results of operations or cash flows.

Dividend Information

Since inception, we have not declared or paid any cash dividends on our common stock, and we have no present intention of paying any dividends on our common stock in the foreseeable future, though we have implemented stock repurchase programs in the past, and our Board of Directors authorized an additional $150.0 million share repurchase program in June 2016. Our Board of Directors periodically reviews our dividend policy to determine whether the declaration of dividends is appropriate. Terms of our credit facility restrict our ability to pay dividends. The restriction is variable based upon our leverage ratio and certain other circumstances, as outlined in the agreement.

Common Stock Repurchases

On June 10, 2016, the Board of Directors approved a stock repurchase program, whereby we may repurchase up to $150.0 million of our common stock over the next two years. This program superseded the previous $100.0 million repurchase authorization. Purchases of our securities during the quarter ended December 31, 2016 are shown in the table below.

Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the other sections of this 2016 10-K, including the Special Note on Forward-looking Statements and Part I, “Item 1A — Risk Factors.”

OVERVIEW

On Assignment provides services through two operating segments, the Apex Segment and the Oxford Segment, with each addressing different sectors of the professional staffing market with distinct business models attuned to those sectors. The Apex Segment provides a broad spectrum of technical, scientific, digital and creative professionals for contract, contract-to-hire and permanent placement positions to Fortune 1000 and mid-market clients across the United States and Canada. Our businesses in this segment include Apex Systems, Apex Life Sciences and Creative Circle. The Oxford Segment provides specialized staffing, permanent placement and consulting services in select skill and geographic markets. Our businesses in this segment include Oxford, CyberCoders and Life Sciences Europe.

Critical Accounting Policies

Our accounting policies are described in “Note 1. Summary of Significant Accounting Policies”, in Item 8 of this report. Our financial statements are prepared in conformity with accounting principles generally accepted in the United States (“GAAP”), which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates. We consider the following policies to be most critical in understanding the judgments that are involved in preparing our financial statements and the uncertainties that could impact our results of operations, financial condition and cash flows.

Accounts Receivable Allowances. We estimate an allowance for i) expected credit losses (the inability of customers to make required payments), ii) assignment revenue sales adjustments (e.g., bill rate adjustments, time card adjustments, early pay discounts) and iii) fallouts (permanent placement candidates that do not remain with the client through the contingency period, which is typically 90 days or less). Our estimates are based on a combination of past experience and current trends. In estimating the allowance for expected credit losses we consider the current aging of receivables and we perform a specific review for potential bad debts. The resulting bad debt expense is included in SG&A expenses and assignment revenue sales adjustments and fallouts are reported as reductions to revenues in the Consolidated Statements of Operations and Comprehensive Income. Receivables are written off when deemed uncollectible. If we experience a significant change in collections, billing adjustment or fallout experience, our estimates of the recoverability of accounts receivable could change.

Business Combinations. The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. We determine the estimated fair values after review and consideration of relevant information including discounted cash flows and estimates made by management. Accordingly, these can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates. We adjust the preliminary purchase price allocation, as necessary, up to one year after the acquisition closing date if we obtain more information regarding asset valuations and liabilities assumed.

Goodwill acquired in business combinations is assigned to the reporting unit(s) expected to benefit from the combination as of the acquisition date. Acquisition-related costs are recognized separately from the acquisition and are expensed as incurred.

Goodwill and Identifiable Intangible Assets. Goodwill and indefinite-lived intangible assets (consisting entirely of trademarks) are tested for impairment on an annual basis as of October 31. Interim testing of goodwill and indefinite-lived intangible assets for impairment is also required whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit or asset below its carrying amount.

In order to test the trademarks for impairment, an Income Approach, specifically a relief from royalty method, was used to estimate the fair value of the trademarks. Principal factors used in the relief from royalty method that require judgment are projected net sales, discount rates, royalty rates and terminal growth assumptions. The estimated fair value of each trademark is compared to its carrying value to determine if impairment exists. There were no indications of impairment of our trademarks in 2016, 2015 and 2014.

Finite-lived intangible assets are amortized over their useful lives and are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Customer relationships are amortized based on relative annual cash flow observed in the valuation of the asset. Contractor relationships and non-compete agreements are amortized using the straight-line method.

unit goodwill after estimating the fair value of intangible assets, with the carrying value of that goodwill. The implied fair value of goodwill is determined using the same approach utilized to estimate the amount of goodwill recognized in a business combination. Based on the annual goodwill impairment tests completed in 2016, 2015 and 2014, there was significant excess fair value over carrying value at all our reporting units and thus no impairment of goodwill.

There are several factors considered in the fair value analysis that require judgment, including discount rates estimated using a weighted average cost of capital and applied in the DCF analysis. There is subjectivity in the estimate of unsystematic risk, or risk specific to the subject reporting unit, and a range of discount rates were used to assess the sensitivity of the value indication to changes in unsystematic risk premium. Holding all other assumptions and approaches constant, an increase of 800 basis points, representing a 60 percent increase in the selected discount rate in the 2016 analysis, would not cause the fair value of any reporting units to be below carrying value. Other primary factors include the terminal growth rate used and the assumptions used to develop the projected financial information (“PFI”). Further, changes in growth assumptions and the resulting impact on operations and costs could affect the fair value estimates. Achieving future cost savings from initiatives, which consider synergies from system and operational improvements in infrastructure and field support, were included in the PFI used in the DCF analysis. Ultimately, future changes in these assumptions may impact the estimated fair value of a reporting unit which may result in the fair value of the reporting unit to be below its carrying value. Changes in market data, including the performance of guideline companies and our own market capitalization, could impact estimates of fair value.

Due to the many variables inherent in the estimation of a reporting unit's fair value and the relative size of recorded goodwill, changes in assumptions may have a material effect on the results of our impairment analysis. Downward revisions of our forecasts or a decline of our stock price resulting in market capitalization significantly below book value could lead to an impairment of goodwill or indefinite-lived intangible assets in future periods.

Results of Operations

Pro forma revenues and gross profit by segment are presented in the tables and discussion below to provide a more consistent basis for comparison between periods. Pro forma data were prepared as if the acquisitions of Creative Circle and LabResource (the “Acquisitions”) were consummated at the beginning of 2014. Although the pro forma segment data are considered non-GAAP measures, they were calculated in the same manner as the consolidated pro forma data (see “Note 4. Acquisitions” in Item 8), which are GAAP measures.

Constant currency data (a non-GAAP measure) are on a pro forma basis and were calculated using the foreign exchange rates from the prior year. The year-over-year fluctuations in foreign exchange rates had an immaterial effect on the revenue growth rates for the year ended December 31, 2016.

Effective January 1, 2016, there was a change to our segment configuration whereby the Apex Segment now includes a small clinical research business, which was previously part of the Oxford Segment. For comparability purposes, prior periods have been adjusted to reflect this change.

	100.0		%	100.0		%	100.0		%

Revenues on an as reported basis increased $375.4 million, or 18.2 percent year-over-year, as a result of (i) the contribution of revenues from Creative Circle, which was acquired in June 2015 and (ii) year-over-year revenue growth from virtually all other operating divisions. On a pro forma basis, revenues were up $261.4 million, or 12.0 percent, year-over-year.

Assignment revenues were $2.3 billion, up 18.8 percent year-over-year on an as reported basis and up 12.7 percent on a pro forma basis. Permanent placement revenues, comprised of direct hire and conversion fees, were $128.1 million, up 8.6 percent year-over-year on an as reported basis and 0.6 percent on pro forma basis. Permanent placement revenues accounted for 5.3 percent of total revenues in 2016, down from 5.7 percent in 2015.

Revenues from our Apex Segment were $1.8 billion, up 23.0 percent year-over-year on an as reported basis. This increase was a result of (i) the inclusion of Creative Circle for the full year 2016 (2015 included results only from the date of acquisition, June 5, 2017), which accounted for 17.7 percent of the segment's revenue and (ii) the high growth of Apex Systems, which accounted for 73.8 percent of the segment's revenues and had a year-over-year growth rate of 15.0 percent, reflecting the continued high demand from our large customer accounts. On a pro forma basis, revenues for the segment were up 14.4 percent year-over-year primarily related to the high growth rate for Apex Systems and Creative Circle. Creative Circle accounted for 17.7 percent of the segment's revenue and grew 17.0 percent year-over-year on a pro forma basis.

Revenues from our Oxford Segment were $603.9 million, up 5.7 percent year-over-year on an as reported basis due to growth in assignment revenues. Assignment revenues were $520.7 million in 2016, up from $485.8 million in 2015. Permanent placement revenues for 2016 were $83.2 million (13.8 percent of the segment's revenues), down from $85.6 million (15.0 percent of the segment's revenues) in 2015. The year-over-year decline in permanent placement revenues reflects lower demand from technology-based clients, specifically early stage companies, the lengthening in the time our clients are taking to make hiring decisions and a tight candidate pool.

Gross Profit and Gross Margins

Consolidated	32.6		%	32.9		%	33.4		%	(0.3	)%	(0.8	)%

Gross profit was $795.2 million, up 17.2 percent in 2016. Gross margin was 32.6 percent, a reduction of 30 basis points year-over-year on an as reported basis. This reduction primarily related to lower mix of permanent placement revenues, which was 5.3 percent of revenues for 2016, down from 5.7 percent in 2015. The gross margin on permanent revenues is over 90 percent. On a pro forma basis, gross margin was down 80 basis points year-over-year due to the lower mix of permanent placement revenues and higher relative growth in the large accounts of Apex Systems, which have lower gross margins.

Apex Segment’s gross profit was $548.4 million, up 24.8 percent year-over-year on an as reported basis. Gross margin for the segment was 29.9 percent, an expansion of 50 basis points year-over-year on an as reported basis due to the inclusion of Creative Circle for the full year (Creative Circle's assignment margin is higher than the other operating units of the Apex Segment). On a pro forma basis, gross margin for the segment was down approximately 40 basis points year-over-year, related to the shift in business mix toward high-volume, lower-margin accounts.

Oxford Segment’s gross profit was $246.8 million, up 3.2 percent year-over-year on an as reported basis. Gross margin for the segment was 40.9 percent, a compression of 100 basis points year-over-year due primarily to a lower mix of permanent placement revenues (13.8 percent of the segment's revenues in 2016, down from 15.0 percent in 2015). The gross margin on permanent placement revenues is over 90 percent.

Selling, General and Administrative Expenses. Selling, general and administrative (“SG&A”) expenses consist primarily of compensation for our field operations and corporate staff, rent, information systems, marketing, telecommunications, public company expenses and other general and administrative expenses. SG&A expenses in 2016 were $565.8 million, or 23.2 percent of revenues, up from $492.2 million or 23.8 percent of revenues in 2015. The increase in SG&A expenses was due to a full year's SG&A expenses from the businesses acquired in 2015 (incrementally $33.4 million) and higher headcount and incentive compensation, both commensurate with growth in the business.

Amortization of Intangible Assets. Amortization of intangible assets was $39.6 million, compared with $34.5 million in 2015. The increase related to amortization from the Acquisitions.

Interest Expense. Interest expense was $32.3 million, up from $26.4 million in 2015. The increase in interest expense was due to higher debt levels related to the June 5, 2015 acquisition of Creative Circle, which was funded primarily from proceeds from borrowings. Interest expense was comprised of (i) interest on the credit facility of $26.7 million, (ii) amortization of deferred loan costs of $3.8 million, (iii) accretion of discount of $0.9 million on the contingent consideration liability related to acquisitions and (iv) $0.9 million third-party fees related to the August 5, 2016 amendment to our credit facility. Interest expense for 2015 was comprised of (i) interest on the credit facility of $22.3 million, (ii) amortization of deferred loan costs of $2.7 million and (iii) accretion of $1.4 million on the contingent consideration liability related to acquisitions. The effective interest rate was 4.2 percent in 2016 and 2015.

Write-Off of Loan Costs. Write-off of loan costs in 2015 was $3.8 million and related to the refinancing of our credit facility in June 2015.

Provision for Income Taxes. The provision for income taxes was $60.2 million compared with $50.5 million in 2015. The effective tax rate for 2016 was 38.2 percent, a decrease from 41.4 percent for 2015. This lower effective tax rate was primarily due to lower percentage of non-deductible expense (mainly disallowed business meals and entertainment) and the benefit of higher tax credits (Research and Development and Work Opportunity Tax Credits).

Income from Continuing Operations. Income from continuing operations was $97.2 million compared with $71.4 million in 2015.

Discontinued Operations. The gain on sale of discontinued operations, net of income tax, was $25.7 million for 2015 for the sale of our Physician Segment.

Net Income. Net income was $97.2 million in 2016, compared with $97.7 million in 2015. Net income for 2015 included the net of tax gain of $25.7 million from the sale of the Physician Segment.

Revenues on an as reported basis increased $340.3 million, or 19.7 percent, as a result of (i) the contribution of $174.9 million in revenues from the Acquisitions and (ii) year-over year organic revenue growth of 9.6 percent (10.5 percent on a constant currency basis). Assignment revenues were $1.9 billion, up from $1.6 billion in 2014. Permanent placement revenues, comprised of direct hire and conversion fees, were $118.0 million, up from $83.0 million in 2014. Permanent placement revenues accounted for 5.7 percent of total revenues, up from 4.8 percent of total revenues in 2014. On a pro forma basis, revenues were up $218.1 million, or 11.1 percent (12.0 percent on a constant currency basis).

The Apex Segment accounted for 72.3 percent of consolidated revenues in 2015. Its revenues on an as reported basis were $1.5 billion, up 24.7 percent year-over-year. This increase was a result of (i) the contribution of $167.2 million in revenues from Creative Circle and (ii) year-over-year organic revenue growth of 10.7 percent. On a pro forma basis, revenues were up 12.7 percent. Apex’s year-over-year pro forma growth rate increased over the course of 2015 from 8.3 percent in the first quarter to 17.3 percent in the fourth quarter. This resulted mainly from the accelerating growth rate of Apex Systems, the Segment's core IT services business (which accounted for 73.5 percent of the segment’s pro forma revenues) and continued high growth from Creative Circle. The accelerating revenue growth of Apex Systems reflected, among other things, higher demand in our end markets and improved productivity from our sales consultants, including the contribution from headcount added during the hiring surge in the second half of 2014.

The Oxford Segment accounted for 27.7 percent of consolidated revenues in 2015. Its revenues on an as reported basis were $571.4 million, up 8.5 percent year-over-year. This increase was a result of (i) year-over year organic revenue growth of 7.0 percent (9.9 percent on a constant currency basis) and (ii) the contribution of $7.7 million in revenues from LabResource. On a pro forma basis, Oxford’s revenues were $574.0 million, up 6.9 percent year-over-year (10.1 percent on a constant currency basis). Oxford’s assignment revenues were $488.4 million on a pro forma basis, up 3.9 percent year-over-year (7.5 percent on a constant currency basis). Its permanent placement revenues grew 28.2 percent year-over-year on a pro forma basis and accounted for 14.9 percent of its total revenues.

Gross profit is comprised of revenues less costs of services. Costs of services consist primarily of compensation for our contract professionals and assignment related expenses. Gross profit for the year was $678.7 million on an as reported basis, up 21.8 percent year-over-year. Gross margin was 32.9 percent, an expansion of 60 basis points over 2014. This expansion related to the higher mix of permanent placement revenues and the inclusion of Creative Circle, which has a higher assignment gross margin than our other divisions. On a pro forma basis, our consolidated gross margin was 33.4 percent, down approximately 10 basis points year-over-year.

The Apex Segment accounted for 64.8 percent of consolidated gross profit in 2015. Its gross profit on an as reported basis was $439.6 million, up 30.0 percent, as a result of (i) contribution of $71.4 million from Creative Circle and (ii) year-over-year organic revenue growth of 10.7 percent. Gross margin for the segment was 29.4 percent, an expansion of 120 basis points year-over-year due to the inclusion of Creative Circle. On a pro forma basis, gross margin was 30.3 percent, down slightly from 2014 primarily due to changes in business mix.

The Oxford Segment accounted for 35.2 percent of consolidated gross profit in 2015. Its gross profit on an as reported basis was $239.1 million, up 9.0 percent year-over-year as a result of the increase in revenues. Its gross margin was 41.9 percent, an expansion of 20 basis points year-over-year due to the higher mix of permanent placement revenues.

Selling, General and Administrative Expenses. Selling, general and administrative expenses consists primarily of compensation for our field operations and corporate staff, rent, information systems, marketing, telecommunications, public company expenses and other general and administrative expenses. SG&A expenses in 2015 were $492.2 million, or 23.8 percent of revenues, up from $397.5 million or 23.0 percent of revenues in 2014. The increase in SG&A expenses was due to (i) $35.3 million from the operations of Creative Circle and LabResource, (ii) $14.9 million of acquisition, integration and strategic planning expenses and (iii) higher compensation costs due to an increase in headcount.

Amortization of Intangible Assets. Amortization of intangible assets was $34.5 million compared with $22.1 million in 2014. The increase related to amortization from the Acquisitions.

Interest Expense. Interest expense was $26.4 million compared with $12.7 million in 2014. The increase in interest expense was primarily due to higher debt levels and an increase in the effective interest rate. Interest expense was comprised of (i) interest on the credit facility of $22.3 million, (ii) amortization of deferred loan costs of $2.7 million and (iii) accretion of $1.4 million on the contingent consideration liability related to acquisitions. Interest expense in 2014 was comprised of (i) interest on the credit facility of $11.3 million and (ii) amortization of capitalized loan costs of $1.4 million. The effective interest rate was 4.2 percent in 2015, compared with 3.3 percent in 2014.

Write-Off of Loan Costs. Write-off of loan costs in 2015 was $3.8 million and related to the refinancing of our credit facility in June 2015.

Provision for Income Taxes. The provision for income taxes was $50.5 million compared with $51.6 million in 2014. The annual effective tax rate was 41.4 percent for 2015, up from 41.2 percent for 2014. The year-over-year increase in the effective tax rate primarily related to non-deductible expenses of $2.8 million for the increase in the earn-out obligation for CyberCoders.

Income from Continuing Operations. Income from continuing operations was $71.4 million compared with $73.5 million in 2014.

Discontinued Operations. Discontinued operations include the net operating results of our Physician Segment (which was sold in February 2015) and our European retained search business (which was shut down in December 2014). Discontinued operations for 2015 included the net of tax gain of $25.7 million from the sale of the Physician Segment. Income from discontinued operations, net of income taxes, was $0.5 million in 2015 and $3.7 million in 2014.

Net Income. Net income was $97.7 million in 2015, compared with $77.2 million in 2014. Net income for 2015 included the net of tax gain of $25.7 million from the sale of the Physician Segment.

Liquidity and Capital Resources

Our working capital (current assets less current liabilities) at December 31, 2016 was $275.0 million and our cash and cash equivalents were $27.0 million, including $10.8 million held in foreign countries, which is not available to fund domestic operations as we do not intend to repatriate cash held in foreign countries. Our cash flows from operating activities and borrowings under our credit facilities have been our primary source of liquidity and have been sufficient to fund our working capital and capital expenditure needs. Our working capital requirements are primarily driven by the overall growth in our business and debt service requirements. We believe that our expected cash flows and availability under our revolving credit facility will be sufficient to meet our obligations, working capital requirements and capital expenditures for the next 12 months.

Net cash provided by operating activities was $196.3 million in 2016 compared with $117.5 million in 2015. The increase primarily related to higher net income, adjusted for non-cash items (e.g., depreciation, amortization, stock-based compensation, etc.), which was $215.4 million for 2016, up from $174.0 million in 2015. This improvement related to the growth in the business and the inclusion of Creative Circle, which was acquired in June 2015. The increase in cash provided by operating activities was also due to changes in operating assets and liabilities. In 2016 changes in operating assets and liabilities reduced cash provided by operating activities by $19.1 million compared with $56.5 million for 2015. The changes in operating assets and liabilities in 2016 included higher accrued payroll and contract professional pay at year end, which was related to the growth in the business and the timing of payments and had a beneficial effect on total cash provided by operating activities. For 2015, changes in operating assets and liabilities included $14.4 million in income taxes paid related to the gain from the sale of the Physician Segment.

Net cash used in investing activities was $22.0 million in 2016 compared with $461.5 million in 2015. Net cash used in investing activities for 2016 was comprised of $27.1 million used to purchase property and equipment and $6.0 million collected from the release of escrow from the sale of our Physician Segment. Net cash used in investing activities in 2015 was comprised of the cash portion of our Creative Circle and LabResource acquisitions of $552.8 million and cash paid for capital expenditures for information technology projects, leasehold improvements and various property and equipment purchases of $24.7 million, partially offset by the net proceeds from the sale of the Physician Segment of $115.4 million.

Net cash used in financing activities was $171.0 million in 2016, compared with $337.7 million provided by financing activities in 2015. Net cash used in financing activities for 2016 consisted primarily of $129.0 million in principal payments of long-term debt, $41.1 million used for repurchases of our common stock, and $16.8 million in payments of contingent considerations (total payment of $21.6 million, of which $16.8 million was cash used in financing activities and $4.8 million was cash used in operating activities). Net cash provided by financing activities in 2015 was primarily comprised of proceeds of $875.0 million from new borrowings on the new credit facility, partially offset by $516.1 million in principal payments of long-term debt and $23.9 million debt issuance costs.

On June 5, 2015, we entered into a $975.0 million credit facility. The funds were used to repay the old credit facility and to fund the cash portion of the purchase of Creative Circle (see “Note 4. Acquisitions” in Item 8). This facility consists of (i) an $825.0 million seven-year term B loan facility and (ii) a $150.0 million five-year revolving credit facility. The credit facility was amended on August 5, 2016, resulting in a 25 basis points reduction in the interest rate for the term B loan facility. Related to the August 5, 2016 amendment, we incurred $0.9 million of third-party fees which are included in interest expense in the consolidated statements of operations and comprehensive income for the year ended December 31, 2016. The revolving credit facility remains unchanged.

Under terms of the credit facility, we are required to make minimum quarterly payments of $2.1 million and mandatory prepayments, subject to specified exceptions, from excess cash flow and with the proceeds of asset sales, debt issuances and specified other events. Because of the principal payments made through December 31, 2016, no additional minimum quarterly payments are required. The outstanding balance on the facility at December 31, 2016 was $656.0 million (see “Note 7. Long-Term Debt” in Item 8). The maximum ratio of consolidated funded debt to consolidated EBITDA steps down at regular intervals from 4.00 to 1.00 as of December 31, 2016, to 3.25 to 1.00 as of March 31, 2018 and thereafter. As of December 31, 2016, the leverage ratio was 2.32 to 1.00. Additionally, the credit facility, which is secured by substantially all of our assets, provides for certain limitations on our ability to, among other things, incur additional debt, offer loans and declare dividends. As of December 31, 2016, we had $146.0 million of borrowings available under our revolving credit facility, after excluding our unused stand-by letters of credit of $4.0 million at December 31, 2016.

On June 10, 2016, the Board of Directors approved a stock repurchase program whereby we may repurchase up to $150.0 million of its common stock over the following two years. During the year ended December 31, 2016 we purchased 1,133,553 shares for $43.1 million ($38.01 average price per share). The remaining authorized amount under this program at December 31, 2016 is $106.9 million.

Commitments and Contingencies

We lease space for our corporate and branch offices. Rent expense was $25.6 million in 2016, $21.6 million in 2015 and $17.6 million in 2014.

The following table sets forth, on an aggregate basis, excluding discontinued operations, at December 31, 2016, the amounts of specified contractual cash obligations required to be paid in the future periods shown (in thousands):



Contractual Obligations	Less than 1 year		1-3 years		3-5 years		More than 5 years		Total
Long-term debt obligations ¹	$	22,960	$	45,920	$	45,920	$	665,567	$	780,367
Operating lease obligations	19,458		31,919		20,744		10,742		82,863

Total	$	52,281	$	85,799	$	69,325	$	680,308	$	887,713

____________

⁽¹⁾ Long-term debt obligations include interest calculated based on the rates in effect at December 31, 2016.

For additional information about these contractual cash obligations, see “Note 7. Long-Term Debt” and “Note 8. Commitments and Contingencies” in Item 8. Purchase obligations are non-cancelable software license/maintenance agreements, software subscriptions and job board service agreements.

We have large retention policies for our workers’ compensation liability exposures. The workers' compensation loss reserves are based upon an actuarial report obtained from a third party and determined based on claims filed and claims incurred but not reported. We account for claims incurred but not yet reported based on estimates derived from historical claims experience and current trends of industry data. Changes in estimates, differences in estimates, and actual payments for claims, are recognized in the period that the estimates changed or the payments were made. The workers' compensation loss reserves were approximately $1.8 million at December 31, 2016 and 2015, net of anticipated insurance and indemnification recoveries of $14.0 million and $13.2 million, at December 31, 2016 and 2015, respectively. We have unused stand-by letters of credit outstanding to secure obligations for workers’ compensation claims with various insurance carriers. The unused stand-by letters of credit at December 31, 2016 and 2015 were $4.0 million and $3.5 million, respectively.

At December 31, 2016 and 2015, we have an income tax reserve in other long-term liabilities related to uncertain tax positions of $1.3 million and $0.8 million, respectively. We have omitted this liability from the table above due to the inherent uncertainty regarding the timing and amount of payments related to uncertain tax positions. We are unable to make reasonably reliable estimates of the period of cash settlement since the statute of limitations might expire without examination by the respective tax authority.

We are involved in various other legal proceedings, claims and litigation arising in the ordinary course of business. However, based on the facts currently available, we do not believe that the disposition of matters that are pending or asserted will have a material effect on our consolidated financial statements.

Off-Balance Sheet Arrangements

As of December 31, 2016, we had no off-balance sheet arrangements.

Accounting Standards Updates

See “Note 2. Accounting Standards Update”, in Item 8 for a discussion of new accounting pronouncements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to certain market risks arising from transactions in the normal course of business, principally risks associated with foreign currency fluctuations and interest rates.

Foreign Currency Fluctuations. Our exposure to fluctuations in foreign currency exchange rates relates primarily to our foreign subsidiaries. Exchange rates impact the U.S. dollar value of our reported earnings, investments in our foreign subsidiaries and intercompany transactions with our foreign subsidiaries. Operations outside of the United States are less than five percent of consolidated revenues. Fluctuations in currency exchange rates impact the U.S. dollar amount of our stockholders’ equity. The assets and liabilities of our non-U.S. subsidiaries are translated into U.S. dollars at the exchange rates in effect at period end. The resulting translation adjustments are recorded in stockholders’ equity as a component of accumulated other comprehensive income. Based on the relative size and nature of our foreign operations, we do not believe that a 10 percent change in the value of foreign currencies relative to the U.S. dollar would have a material impact on our financial statements.

Interest Rate Risk. Our exposure to interest rate risk is associated with our debt instruments. See “Note 7. Long-Term Debt” in Part II, Item 8 of this 2016 10-K for a further description of our debt instruments. A hypothetical 100 basis point change in interest rates on variable rate debt would have resulted in interest expense fluctuating approximately $6.6 million based on $656.0 million of debt outstanding for any 12-month period. We have not entered into any market risk sensitive instruments for trading purposes.

Item 8. Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of On Assignment, Inc.

Calabasas, California

We have audited the accompanying consolidated balance sheets of On Assignment, Inc. and subsidiaries (the "Company") as of December 31, 2016 and 2015, and the related consolidated statements of operations and comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2016. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits 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 the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of On Assignment, Inc. and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's 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 and our report dated March 1, 2017 expressed an unqualified opinion on the Company's internal control over financial reporting.

ON ASSIGNMENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Principles of Consolidation. The consolidated financial statements include the accounts of On Assignment, Inc. and its wholly-owned subsidiaries (the “Company”). All intercompany accounts and transactions have been eliminated.

Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition. Revenues from contract assignments, net of sales adjustments and discounts, are recognized when earned, based on hours worked by the Company’s contract professionals on a weekly basis. Permanent placement revenues (direct hire and conversion fees) are recognized as revenues when employment candidates or contract professionals begin permanent employment. The Company records a sales allowance against consolidated revenues, which is an estimate based on historical billing adjustment experience. The billing adjustment reserve includes an allowance for fallouts. Fallouts are permanent placement candidates that do not remain with the client through the contingency period, which is typically 90 days or less. The Company includes reimbursed expenses, in revenues and the associated amounts of reimbursable expenses in costs of services.

The Company records revenues on a gross basis as a principal or on a net basis as an agent depending on the arrangement. The key indicators as to whether it acts as a principal or an agent are whether the Company (i) has the direct contractual relationships with its customers, (ii) bears the risks and rewards of the transactions and (iii) has the discretion to select the contract professionals and establish their price.

Costs of Services. Costs of services include direct costs of contract assignments consisting primarily of payroll, payroll taxes and benefit costs for the Company’s contract professionals. Costs of services also include assignment expenses, many of which are reimbursable by the client.

Income Taxes. Income taxes are accounted for using the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized.

The Company makes a comprehensive review of its uncertain tax positions regularly. An uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed return, or planned to be taken in a future tax return or claim that has not been reflected in measuring income tax expense for financial reporting purposes. In general, until these positions are sustained by the taxing authorities or statutes expire for the year that the position was taken, the Company does not recognize the tax benefits resulting from such positions and reports the tax effects as a liability for uncertain tax positions.

Foreign Currency Translation. The functional currency of the Company’s foreign operations is their local currency, and as such, their assets and liabilities are translated into U.S. dollars at the rate of exchange in effect on the balance sheet date. Revenues and expenses are translated at the average rates of exchange prevailing during each monthly period. The related translation adjustments are recorded as cumulative foreign currency translation adjustments in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Gains and losses resulting from foreign currency transactions, which are not material, are included in selling, general and administrative (“SG&A”) expenses in the Consolidated Statements of Operations and Comprehensive Income.

Cash and Cash Equivalents. The Company considers all highly liquid investments with a maturity of three months or less on the date of purchase to be cash equivalents.

Accounts Receivable Allowances. The Company estimates an allowance for i) expected credit losses (the inability of customers to make required payments), ii) assignment revenue sales adjustments (e.g., bill rate adjustments, time card adjustments, early pay discounts) and iii) fallouts (permanent placements that do not complete the contingency period, which is typically 90 days or less). These estimates are based on a combination of past experience and current trends. In estimating the allowance for expected credit losses consideration is given to the current aging of receivables and a specific review for potential bad debts. The resulting bad debt expense is included in SG&A expenses and assignment revenue sales adjustments and fallouts are reported as reductions to revenues in the Consolidated Statements of Operations and Comprehensive Income. Receivables are written off when deemed uncollectible.

Property and Equipment. Property and equipment are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets, generally three to five years. Leasehold improvements are amortized over the shorter of the life of the related asset or the remaining term of the lease. Costs associated with customized internal-use software systems that have reached the application development stage and meet recoverability tests are capitalized. Such capitalized costs include external direct costs utilized in developing or obtaining the applications and payroll and payroll-related expenses for employees who are directly associated with the application development.

Business Combinations. The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. The Company determines the estimated fair values after review and consideration of relevant information including discounted cash flows and estimates made by management. Accordingly, these can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates. The Company adjusts the preliminary purchase price allocation, as necessary, up to one year after the acquisition closing date if it obtains more information regarding asset valuations and liabilities assumed.

Goodwill is tested at the reporting unit level which is generally an operating segment or one level below the operating segment level where a business operates and for which discrete financial information is available and reviewed by segment management. The first step (“Step 1”) of the two-step testing process estimates and then compares the fair value of a reporting unit to the reporting unit's carrying value. The Company determines the fair value of each reporting unit by weighting fair value estimates using three accepted valuation methodologies: i) the Income Approach, specifically a discounted cash flow (“DCF”) analysis, (ii) a Market Approach, specifically the guideline company method (“GCM”) and (iii) a Market Approach, specifically the similar transactions method (“STM”). If after performing Step 1 of the goodwill impairment test, the fair value of equity of any reporting unit does not exceed the carrying value of equity, the Company performs a second step (“Step 2”) of the goodwill impairment test for that reporting unit. Step 2 measures the amount of goodwill impairment by comparing the implied fair value of the respective reporting unit goodwill after estimating the fair value of intangible assets, with the carrying value of that goodwill. The implied fair value of goodwill is determined using the same approach utilized to estimate the amount of goodwill recognized in a business combination. Based on the annual goodwill impairment tests completed in 2016, 2015 and 2014, there was significant excess fair value over carrying value at all the reporting units and thus no impairment of goodwill.

Impairment or Disposal of Long-Lived Assets. The Company evaluates long-lived assets, other than goodwill and identifiable intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss is recognized when the sum of the undiscounted future cash flows is less than the carrying amount of the asset, in which case a write-down is recorded to reduce the related asset to its estimated fair value. There were no significant impairments of long-lived assets in 2016, 2015 and 2014.

Workers’ Compensation Loss Reserves. The Company carries retention policies for its workers’ compensation liability exposures. In connection with these programs, the Company pays a base premium plus actual losses incurred, not to exceed certain stop-loss limits. The Company is insured for losses above these limits, both per occurrence and in the aggregate. The Company estimates its workers' compensation loss reserves based on an actuarial report obtained from a third party which is determined based on claims filed and claims incurred but not reported. The Company accounts for claims incurred but not yet reported based on estimates derived from historical claims experience and current trends of industry data. Changes in estimates and differences in estimates and actual payments for claims are recognized in the period that the estimates changed or the payments were made.

Contingencies. The Company records an estimated loss from a loss contingency when information available prior to issuance of its financial statements indicates it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements, and the amount of the loss can be reasonably estimated. Accounting for contingencies, such as legal settlements and workers’ compensation matters, requires the Company to use judgment.

Stock-Based Compensation. The Company records compensation expense for restricted stock awards and restricted stock units based on the fair market value of the awards on the date of grant. Compensation expense for performance-based awards is measured based on the amount of shares ultimately expected to vest, estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. The Company accounts for stock options granted and employee stock purchase plan shares based on an estimated fair market value using a Black-Scholes option valuation model. This methodology requires the use of subjective assumptions including expected stock price volatility and the estimated life of each award. The fair value of equity-based compensation awards less the estimated forfeitures is amortized over the vesting period of the award.

Concentration of Credit Risk. Financial instruments that potentially subject the Company to credit risks consist primarily of cash, cash equivalents and trade receivables. The Company places its cash and cash equivalents in low risk investments with quality credit institutions and limits the amount of credit exposure with any single institution above FDIC insured limits. Concentration of credit risk with respect to accounts receivable is limited because of the large number of geographically dispersed customers, thus spreading the trade credit risk. The Company performs ongoing credit evaluations to identify risks and maintains an allowance to address these risks.

Advertising Costs. Advertising costs, which are expensed as incurred, were $5.0 million in 2016, $3.6 million in 2015, and $4.8 million in 2014 and are included in SG&A expenses.

2. Accounting Standards Update

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which outlines a comprehensive new revenue recognition model designed 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 or services. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606)-Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which further clarifies the implementation guidance on principal versus agent considerations contained in ASU 2014-09. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606)-Identifying Performance Obligations and Licensing, which further clarifies the implementation guidance relating to identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606)-Narrow-Scope Improvements and Practical Expedients, which further clarifies guidance on collectability, noncash consideration, presentation of sales tax, practical expedients and transition. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which makes minor corrections or minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. These standards, pursuant to ASU No. 2015-14, Revenue from Contracts with Customers-Deferral of the Effective Date (Topic 606) issued by the FASB in August 2015, will be effective for annual periods (including interim periods) beginning after December 15, 2017. The Company commenced its assessment of these new standards during the second half of 2016, developed a project plan to guide the implementation and is evaluating the impact these new standards will have on its consolidated financial statements.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquirer must record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting has been completed at the acquisition date. The Company adopted this guidance on January 1, 2016 and there was no impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which is intended to improve financial reporting about leasing transactions. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. It is effective for annual periods (including interim periods) beginning after December 15, 2018, and early adoption is permitted. The Company is evaluating the impact the provisions of ASU 2016-02 will have on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718), which is intended to simplify the accounting for the taxes related to stock-based compensation. Under the new guidance excess tax benefits and tax deficiencies will be recognized as income tax benefit or expense in the income statement, rather than in the balance sheet within additional paid-in capital. The new guidance also makes amendments to the following areas: presentation of excess tax benefits or tax deficiencies on the statement of cash flows, accounting for forfeitures and presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet minimum statutory withholding requirements. It is effective for annual periods (including interim periods) beginning after December 15, 2016. The Company adopted this guidance on January 1, 2017 and as required will prospectively present excess tax benefits and deficiencies in its consolidated statement of operations and comprehensive income (no longer as increases to additional paid in capital on its consolidated balance sheet). Additionally the Company will retrospectively present its gross excess tax benefits as cash flows from operating activities in its consolidated statements of cash flows (no longer as cash flows from financing activities). The tax effect related to stock-based awards is dependent on the Company's stock price and as a result it is subject to significant fluctuations. The Company will continue to estimate expected forfeitures to determine the amount of compensation expense to be recognized.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update is effective for annual periods (including interim periods) beginning after December 15, 2017, should be applied retrospectively, and early adoption is permitted. The Company adopted this guidance as of December 31, 2016 and there was no impact on its consolidated financial statements.

In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements, which clarifies and removes inconsistencies in key areas of accounting principles generally accepted in the United States (“GAAP”) and is effective immediately. The Company adopted this guidance in December 2016 and there was no impact on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business. The amendments in this update clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-03, Intangibles-Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment. The new guidance eliminates Step 2 of the goodwill impairment test which requires companies to calculate the implied fair value of goodwill, determined in the same manner as the amount of goodwill recognized in a business combination, and using a hypothetical purchase price allocation. Under the new guidance, goodwill impairment will now be measured as the amount by which a reporting unit’s carrying value exceeds its fair value. This update is effective for annual periods (including interim periods) beginning after December 15, 2017, and early adoption is permitted. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial statements.

3. Property and Equipment

Property and equipment at December 31, 2016 and 2015 consisted of the following (in thousands):



	2016			2015
Furniture, fixtures and equipment	$	14,956		$	14,445
Computers and related equipment	23,286			33,121
Computer software	72,852			52,929
Leasehold improvements	12,670			10,551
Work-in-progress	5,522			4,139

Less -- accumulated depreciation	(72,344		)	(61,989		)
	$	56,942		$	53,196

Depreciation expense related to property and equipment was $22.6 million in 2016, $16.8 million in 2015 and $12.3 million in 2014 and is included in SG&A expenses.

The Company has capitalized costs related to its various technology initiatives. At December 31, 2016 and 2015, the net book value of the property and equipment related to software development was $31.8 million and $15.7 million, respectively, which included work-in-progress of $3.1 million and $2.5 million, respectively.

4. Acquisitions

On June 5, 2015, the Company acquired all of the outstanding shares of the holding company for Creative Circle, LLC (“Creative Circle”). Creative Circle, which is headquartered in Los Angeles, California, was purchased to expand the Company’s technical and creative staffing services. The purchase price consisted of $540.0 million cash, $30.2 million of common stock (794,700 shares of the Company’s common stock) and estimated future contingent consideration which was valued at $13.8 million. Goodwill related to this acquisition totaled $358.0 million and is deductible for income tax purposes. Acquisition expenses of approximately $5.7 million were expensed in 2015 and are included in SG&A expenses.

The final value of the contingent consideration was $15.8 million, an increase of $2.0 million from the initial valuation. This increase consisted of (i) accretion of discount, as the initial value was recorded on a discounted basis and (ii) an increase in the obligation due to higher than expected post-acquisition performance of the acquired business. The $15.8 million obligation was paid in 2016, of which $13.8 million was included in cash used in financing activities and $2.0 million in cash used in operating activities.

The results of operations for the acquisition have been combined with those of the Company from the acquisition date. Creative Circle revenues and income before income taxes included in the consolidated statement of operations and comprehensive income for the year-ended December 31, 2015 were $167.2 million and $22.9 million, respectively.

On April 14, 2015, the Company acquired all of the outstanding shares of LabResource B.V. (“LabResource”) headquartered in Amsterdam, Netherlands for $12.7 million. LabResource was purchased to expand the Company's life sciences staffing business in Europe. Goodwill associated with this acquisition is not deductible for tax purposes. Acquisition expenses of approximately $0.4 million were expensed in 2015 and are included in SG&A expenses. The results of operations for this acquisition have been combined with those of the Company from the acquisition date. LabResource revenues and income before income taxes included in the consolidated statement of operations and comprehensive income for 2015 were $7.7 million and $1.0 million, respectively.

Assets and liabilities of the acquired companies were recorded at their estimated fair values at the dates of acquisition. The excess purchase price over the fair value of net tangible assets and identifiable intangible assets acquired has been allocated to goodwill. The fair value assigned to identifiable intangible assets was determined primarily by using a discounted cash flow method.

The Company's allocation of the purchase price of Creative Circle and LabResource has been finalized and the following table summarizes the allocations (in thousands):



	2015 Acquisitions

(1)	Excluding cash acquired and a $0.9 million adjustment for net working capital in excess of the targeted amount (thereby increasing the actual purchase price paid), the purchase price for Creative Circle was $584.0 million as described in the discussion above.


(2)	Excluding cash acquired and a $0.4 million adjustment for net working capital that was less than the targeted amount (thereby reducing the actual purchase price paid), the purchase price for LabResource was $12.7 million as described in the discussion above.

The following table summarizes (in thousands) the allocation of the purchase price among the identifiable intangible assets for the acquisitions:



		Identifiable Intangible Asset Value
		2015 Acquisitions

7. Long-Term Debt

At December 31, 2016 and 2015, long-term debt consisted of the following (in thousands):



	2016			2015
$150 million revolving credit facility, due June 2020	$	—		$	50,000
$825 million Term B loan facility, due June 2022	656,000			724,000

Unamortized deferred loan costs	(15,645		)	(18,492		)
	$	640,355		$	755,508

On June 5, 2015, the Company entered into a $975.0 million credit facility. The funds were used to repay the old credit facility and to fund the cash portion of the purchase of Creative Circle (see “Note 4. Acquisitions”). The facility consists of (i) an $825.0 million seven-year term B loan facility and (ii) a $150.0 million five-year revolving loan facility.

The credit facility was amended on August 5, 2016, resulting in a 25 basis points reduction in the interest rate for the term B loan facility. Related to the August 5, 2016 amendment, the Company incurred $0.9 million of third-party fees which are included in interest expense in the consolidated statements of operations and comprehensive income for the year ended December 31, 2016.

Borrowings under the term B loan bear interest at LIBOR (floor of 75 basis points), plus 2.75 percent and borrowings under the revolving credit facility bear interest at LIBOR (or the bank’s base rate) plus 0.75 to 2.5 percent depending on leverage levels. A commitment fee of 0.25 to 0.40 percent is payable on the undrawn portion of the revolving credit facility. At December 31, 2016, the interest rate on the term B loan was 3.5 percent, and there were no borrowings under the revolving credit facility.

Under terms of the credit facility, the Company is required to make minimum quarterly payments of $2.1 million and mandatory prepayments, subject to specified exceptions, from excess cash flow and with the proceeds of asset sales, debt issuances and specified other events. Because of the principal payments made through December 31, 2016, no additional minimum quarterly payments are required.

The Company's obligations under the credit facility are guaranteed by substantially all of its direct and indirect domestic subsidiaries and are secured by a lien on substantially all of the Company's tangible and intangible property and by a pledge of all of the equity interests in its direct and indirect domestic subsidiaries.

The credit facility includes various restrictive covenants including the maximum ratio of consolidated funded debt to consolidated EBITDA (4.00 to 1.00 as of December 31, 2016 decreasing to 3.25 to 1.00 on March 31, 2018). The credit facility also contains certain customary limitations including, among other terms and conditions, the Company's ability to incur additional indebtedness, engage in mergers and acquisitions and declare dividends. At December 31, 2016, the Company had a ratio of consolidated funded debt to consolidated EBITDA of 2.32 to 1.00.

At December 31, 2016 the Company was in compliance with all of its debt covenants and had $146.0 million of borrowing available under the revolving credit facility, after excluding the unused stand-by letters of credit of $4.0 million at December 31, 2016.

8. Commitments and Contingencies

The Company leases its facilities and certain office equipment under operating leases, which expire at various dates through 2025. Certain leases contain rent escalations or renewal options or both. Rent expense for all significant leases is recognized on a straight-line basis. Rent expense is included in SG&A expenses and was $25.6 million, $21.6 million and $17.6 million in 2016, 2015 and 2014, respectively. The balance of the deferred rent liability reflected in other current liabilities in the accompanying consolidated balance sheets was $0.6 million and $0.5 million at December 31, 2016 and 2015, respectively, and the balance reflected in other long-term liabilities was $5.2 million and $4.3 million, at December 31, 2016 and 2015, respectively.

The following is a summary of specified contractual cash obligation payments by the Company, as of December 31, 2016 (in thousands):



	Operating Leases		Related Party Leases		Purchase Obligations		Total
2017	$	19,458	$	1,169	$	8,694	$	29,321
2018	17,719		1,302		4,121		23,142
2019	14,200		1,282		1,255		16,737

Total	$	82,863	$	10,413	$	14,070	$	107,346

As a result of the Apex Systems acquisition, the Company leases two properties owned by related parties. Rent expense for these two properties was $1.3 million for each of the years 2016, 2015 and 2014.

Purchase obligations are non-cancelable software license/maintenance agreements, software subscriptions and job board service agreements.

The Company carries large retention policies for its workers’ compensation liability exposures. The workers' compensation loss reserves are based upon an actuarial report obtained from a third party and determined based on claims filed and claims incurred but not reported. The Company accounts for claims incurred but not yet reported based on estimates derived from historical claims experience and current trends of industry data. Changes in estimates, differences in estimates and actual payments for claims, are recognized in the period that the estimates changed or the payments were made. The workers' compensation loss reserves were $1.8 million at December 31, 2016 and 2015, net of anticipated insurance and indemnification recoveries of $14.0 million and $13.2 million, at December 31, 2016 and 2015, respectively. The Company has unused stand-by letters of credit outstanding to secure obligations for workers’ compensation claims with various insurance carriers. The unused stand-by letters of credit at December 31, 2016 and December 31, 2015 were $4.0 million and $3.5 million, respectively.

Certain employees participate in the Company’s Change in Control Severance Plan, or have separate agreements that provide for certain benefits in the event of termination at the Company's convenience or following a change in control, as defined by the plan or agreement. Generally, these benefits are based on the employee’s position with the Company and include severance, continuation of health insurance and a pro rata bonus.

Legal Proceedings

The Company is involved in various legal proceedings, claims and litigation arising in the ordinary course of business. Based on the facts currently available, the Company does not believe that the disposition of matters that are pending or asserted will have a material effect on its consolidated financial statements.

The reconciliation between the amount computed by applying the U.S. federal statutory tax rate of 35.0 percent to income before income taxes and the income tax provision is as follows (in thousands):



	Year Ended December 31,
	2016			2015		2014
Income tax provision at the statutory rate	$	55,089		$	42,669	$	43,768

Other	(1,573		)	1,545		1,507
	$	60,203		$	50,491	$	51,557

As of December 31, 2016, the Company had no federal net operating losses, no state net operating losses and $5.8 million of foreign net operating losses. The foreign net operating losses in the United Kingdom and Spain can be carried forward indefinitely. The Company has recorded a valuation allowance of approximately $1.2 million and $1.0 million at December 31, 2016 and 2015, respectively, related to net operating loss carryforwards.

The Company has not provided deferred income taxes on $16.3 million of undistributed earnings of its foreign subsidiaries as of December 31, 2016 since the Company intends to reinvest these earnings indefinitely. Those earnings are considered to be indefinitely reinvested; accordingly, no provision for U.S. federal and state income taxes has been provided thereon. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with its hypothetical calculation; however, unrecognized foreign tax credit carryforwards would be available to reduce some portion of the U.S. liability.

The Company had gross deferred tax assets of $34.4 million and $29.2 million and gross deferred tax liabilities of $107.5 million and $89.7 million at December 31, 2016 and 2015, respectively. Management has determined the gross deferred tax assets are realizable, with the exception of foreign net operating losses discussed above.

At December 31, 2016, 2015 and 2014, there were $1.3 million to $0.8 million of unrecognized tax benefits that if recognized would affect the annual effective tax rate. The gross unrecognized tax benefit is carried in other long-term liabilities. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The amount of interest and penalties recognized in the financial statements is not significant. The Company believes that it is reasonably possible that a decrease of $0.8 million in unrecognized tax benefits may be recognized by the end of 2017 as a result of a lapse in the statute of limitations. The following is a reconciliation of the total amounts of unrecognized tax benefits (in thousands):



	Year Ended December 31,
	2016		2015			2014
Unrecognized tax benefit beginning of year	$	814	$	848		$	979
Gross increases - tax positions in prior year	479		—			126
Gross decreases - tax positions in prior year	—		(34		)	—
Lapse of the statute of limitations	—		—			(131		)
Discontinued operations	—		—			(126		)
Unrecognized tax benefit end of year	$	1,293	$	814		$	848

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The IRS has commenced an examination of the Company’s U.S. income tax returns for the 2014 tax year. The Company remains subject to U.S. federal income tax examinations for 2013 and subsequent years. For major U.S. states, with few exceptions, the Company remains subject to examination for 2012 and subsequent years. Generally, for the foreign tax jurisdictions, the Company remains subject to examination for 2012 and subsequent years.

10. Earnings per Share

Basic earnings per share are computed using the weighted average number of shares outstanding and diluted earnings per share are computed using the weighted average number of shares and dilutive share equivalents (consisting of non-qualified stock options, restricted stock units and employee stock purchase plan contributions) outstanding during the periods using the treasury stock method.

The following is a reconciliation of the shares used to compute basic and diluted earnings per share (in thousands):



	Year Ended December 31,
	2016	2015	2014
Weighted average number of common shares outstanding used to compute basic earnings per share	53,192	52,259	53,437
Dilutive effect of stock-based awards	555	746	857
Number of shares used to compute diluted earnings per share	53,747	53,005	54,294

There were no significant share equivalents outstanding as of December 31, 2016, 2015 and 2014 that were anti-dilutive when applying the treasury stock method.

11. Stockholders' Equity

On July 21, 2014, the Board of Directors approved a program authorizing the Company to repurchase up to $100.0 million of the Company’s common stock. During 2014, the Company repurchased 3.4 million shares of its common stock under this program at a cost of $100.0 million. All shares repurchased under this program were retired. This resulted in a reduction of $31.2 million in paid-in capital and a reduction of $68.8 million in retained earnings.

On January 16, 2015, the Company's Board of Directors approved a $100.0 million share repurchase program. During 2015, the Company repurchased 43,000 shares of its common stock at a cost of $1.6 million. All shares repurchased under this program were retired, which resulted in a reduction of $0.4 million in paid-in capital and a reduction of $1.2 million in retained earnings.

The Company's stock-based compensation plans accept shares of the Company's common stock as payment for the exercise price of stock options. During 2015 the Company received 46,174 shares, with a $2.2 million value, as payment for the exercise of stock options. Those shares were retired upon receipt, which resulted in a reduction of $0.8 million in paid-in capital and a reduction of $1.4 million in retained earnings.

On June 5, 2015, the Company issued 794,700 shares of its common stock valued at $30.2 million, in connection with the acquisition of Creative Circle.

On June 10, 2016, the Board of Directors approved a stock repurchase program, whereby the Company may repurchase up to $150.0 million of its common stock over the following two years. This program superseded the previous $100.0 million repurchase authorization. During 2016, the Company repurchased 1,133,553 shares of its common stock at a cost of $43.1 million. All shares repurchased under this program were retired, which resulted in a reduction of $11.9 million in paid-in capital and a reduction of $31.2 million in retained earnings.

12. Accumulated Other Comprehensive Income (Loss)

The components of accumulated other comprehensive income (loss) were as follows (in thousands):



	Foreign currency translation adjustment			Changes in fair value of derivative, net of tax			Accumulated other comprehensive income (loss)

13. Stock-Based Compensation and 401(k) Retirement Savings Plan

Effective June 3, 2010, the stockholders of the Company approved the adoption of the On Assignment, Inc. 2010 Incentive Award Plan, (the “2010 Plan”), which replaced the Company’s Restated 1987 Stock Option Plan. The 2010 Plan permits the grant of stock options, including incentive stock options, nonqualified stock options, restricted stock awards, dividend equivalent rights, stock payments, deferred stock, restricted stock units (“RSUs”), performance shares and other incentive awards, stock appreciation rights and cash awards to its employees, directors and consultants. As of December 31, 2016, there were 2,503,110 shares available for issuance under the 2010 Plan.

Effective May 15, 2012, the Board of Directors adopted the 2012 Employment Inducement Incentive Award Plan, (the “2012 Plan”). The 2012 Plan allows for grants of stock to employees as employment inducement awards pursuant to New York Stock Exchange rules. The terms of 2012 Plan are similar to the 2010 Plan. As of December 31, 2016, there were 174,975 shares available for issuance under the 2012 Plan.

The Company believes that stock-based compensation aligns the interests of its employees and directors with those of its stockholders. Stock-based compensation provides incentives to retain and motivate executive officers and key employees responsible for driving Company performance and maintaining important relationships that contribute to the growth of the Company.

Stock-based compensation expense is included in SG&A expenses in the accompanying consolidated statements of operations and comprehensive income and was classified as follows (in thousands):



	Year Ended December 31,
	2016		2015		2014
Continuing operations	$	27,024	$	22,018	$	15,623
Discontinued operations	—		—		576
Total	$	27,024	$	22,018	$	16,199

The Company recognized an income tax benefit for stock-based compensation arrangements of $2.7 million, $6.6 million and $4.7 million in 2016, 2015 and 2014, respectively.

Restricted Stock Units

The fair value of each RSU is based on the fair market value of the awards on the grant date and the Company records compensation expense based on this value, net of a forfeiture rate. The forfeiture rate estimates the number of awards that will eventually vest and is based on historical vesting patterns for RSUs.

A summary of the status of the Company’s unvested RSUs as of December 31, 2016 and changes during the year then ended are presented below:



	Service Conditions		Performance and Service Conditions		Total		Weighted Average Grant-Date Fair Value Per Unit
Unvested RSUs outstanding at December 31, 2015	465,369		881,251		1,346,620			$	36.31

Unvested RSUs outstanding at December 31, 2016	279,262		916,593		1,195,855			$	38.78
Unvested and expected to vest RSUs outstanding at December 31, 2016	259,412		865,621		1,125,033			$	38.68

____

⁽¹⁾ Granted RSUs with Performance and Service Conditions include 10,720 RSUs for one grant classified as a liability award as of December 31, 2016, for which $0.5 million expense was recognized in 2016 and has a service period of approximately one year.

The total number of shares vested in the table above includes 197,557 shares surrendered by the employees to the Company for payment of income taxes. The surrendered shares are available for issuance under the Plan.

The weighted-average grant-date fair value of RSUs granted during 2016, 2015 and 2014 was $36.07, $40.49 and $33.66 per award, respectively. The fair value of RSUs that vested during 2016, 2015 and 2014, was $21.7 million, $24.3 million and $21.3 million, respectively.

As of December 31, 2016, there was unrecognized compensation expense of $22.7 million related to unvested RSUs based on awards that are expected to vest. The unrecognized compensation expense is expected to be recognized over a weighted-average period of two years.

Liability Awards

Liability awards have a performance component and vest over one to three years. The performance goals are approved by the Compensation Committee of the Company’s Board of Directors. The Company classifies these awards as liabilities until the number of shares is determined, in accordance with the grant. The number of shares is determined by dividing the final award liability balance by the Company’s closing stock price on the settlement dates. This liability is included in other accrued expenses in the accompanying Consolidated Balance Sheets.

The following table summarizes the balance of liability awards and expense during the years presented (in thousands):



	2016		2015			2014
Balances of liability awards at beginning of year	$	—	$	1,453		$	2,500
Expense for grants	465		—			500
Settled	—		(1,453		)	(1,497		)
Canceled	—		—			(50		)
Balance of liability awards at end of year	$	465	$	—		$	1,453

There was no significant unrecognized compensation expense for liability awards as of December 31, 2016.

Stock Options

Subsequent to 2012 the Company has not granted any stock options. The fair value of stock option grants was estimated on the grant date using the Black-Scholes option pricing model. The Company records compensation expense based on this value. The following summarizes pricing and term information for options outstanding as of December 31, 2016:



					Options Outstanding					Options Exercisable

There were no incentive stock options outstanding as of December 31, 2016 and none were granted during 2016. The total intrinsic value of options exercised during 2016, 2015 and 2014 was $4.7 million, $10.9 million and $3.9 million, respectively.

Employee Stock Purchase Plan

Effective June 3, 2010, the stockholders of the Company approved the On Assignment 2010 Employee Stock Purchase Plan (the “ESPP”) for issuance of up to 3,500,000 shares of common stock. The ESPP allows eligible employees to purchase common stock of the Company, through payroll deductions, at a 15 percent discount of the lower of the market price on the first day or the last day of the semi-annual purchase periods. The ESPP is intended to qualify as an employee stock purchase plan under the Internal Revenue Service (“IRS”) Code Section 423. Eligible employees may contribute up to a certain percentage set by the plan administrator of their eligible earnings toward the purchase of the stock (subject to certain IRS limitations). As of December 31, 2016, there were 2,300,321 shares available for issuance under the ESPP.

Shares of common stock are transferred to participating employees at the conclusion of each six-month offering period, which ends on the last business day of the month in March and September each year. Compensation expense is measured using a Black-Scholes option-pricing model. The table below presents the average fair value per share of shares purchased and the compensation expense under the ESPP (dollars in thousands, except per share amounts):



Year Ended December 31,	Average fair value per share	Shares	Expense
2016	$9.05	242,303	$	2,497
2015	$7.77	204,401	$	1,586
2014	$8.35	207,805	$	1,756

401(k) Retirement Savings Plan

The Company maintains various 401(k) retirement savings plans for the benefit of eligible employees. Under terms of these plans, eligible employees are able to make contributions to these plans on a tax-deferred basis. The Company makes matching contributions, some of which are discretionary. The Company made contributions to the 401(k) plans of $5.6 million, $7.6 million and $7.5 million for the years ended December 31, 2016, 2015 and 2014, respectively.

14. Business Segments

On Assignment provides services through two operating segments, the Apex Segment and the Oxford Segment, with each addressing different sectors of the professional staffing market with distinct business models attuned to those sectors. The Apex Segment provides a broad spectrum of technical, scientific, digital and creative professionals for contract, contract-to-hire and permanent placement positions to Fortune 1000 and mid-market clients across the United States and Canada. Businesses in this segment include Apex Systems, Apex Life Sciences (formerly known as Lab Support) and Creative Circle. The Oxford Segment provides specialized staffing, permanent placement and consulting services in select skill and geographic markets. Businesses in this segment include Oxford Global Resources, LLC, CyberCoders and Life Sciences Europe.

Effective January 1, 2016, there were two changes to the Company's segment configuration: 1) the Apex Segment now includes a small clinical research business which was previously included in the Oxford Segment and 2) costs associated with personnel located at the Corporate office that have shared services roles and support certain of the businesses, primarily within the Oxford Segment, are now presented in the segments they support whereas previously they were presented within Corporate. For comparability purposes, prior periods have been adjusted to reflect these changes.

The Company’s management evaluates the performance of each segment primarily based on revenues, gross profit and operating income. The information in the following tables is derived directly from the segments’ internal financial reporting used for corporate management purposes. The Company's management does not evaluate, manage or measure performance of segments using asset information and such information is not readily available. Accordingly, assets by reportable segment are not disclosed.

The following tables present revenues, gross profit, operating income and amortization by reportable segment (in thousands):

15. Fair Value Measurements

The recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value based on their short-term nature. Long-term debt recorded in the Company’s Consolidated Balance Sheets at December 31, 2016 was $640.4 million (net of $15.6 million of unamortized deferred loan costs, see “Note 7. Long-Term Debt”). The fair value of the long-term debt at that same date was $662.6 million as determined using Level 1 inputs (quoted prices in active markets for identical liabilities) from the fair value hierarchy.

Related to its acquisitions, the Company had obligations to pay contingent consideration in cash if certain performance targets were met. Contingent consideration obligations were paid during the current year. Prior to completing the performance period, the fair value of the contingent consideration was determined using an expected present value technique. Expected cash flows were determined using the probability-weighted average of possible outcomes that would occur should certain financial metrics be reached. There is no market data available to use in valuing the contingent consideration, therefore, the Company developed its own assumptions related to the future financial performance of the businesses to evaluate the fair value of these liabilities. As such, the contingent consideration was classified within Level 3 inputs (unobservable inputs) from the fair value hierarchy. The fair value of the liability for contingent consideration was established at the time of the acquisition and finalized by the end of the measurement period. The fair value was then remeasured on a recurring basis with changes due to the accretion of the present value discount recorded in interest expense, and changes related to new developments in expected performance recorded in SG&A expenses. In 2016, there was accretion of discount totaling $0.9 million and a reduction in expense of $0.3 million related to a decrease in the obligation. In 2015, there was accretion of discount totaling $1.4 million and expense of $2.8 million related to an increase in the obligation.

The following table summarizes the balance of the contingent consideration and changes for the periods presented (in thousands):



	Year Ended December 31,
	2016			2015
Balance at beginning of year	$	(20,981	)	$	(3,000	)
Additions for acquisitions	—			(13,814		)
Payments on contingent consideration	21,594			—
Fair value adjustments	(613		)	(4,167		)
Balance at end of year	$	—		$	(20,981	)

Certain assets and liabilities, such as goodwill, are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). For 2016 and 2015, no fair value adjustments were required for non-financial assets or liabilities.

16. Unaudited Quarterly Results

The following tables present unaudited quarterly financial information. In the opinion of the Company’s management, the quarterly information contains all adjustments, consisting only of normal recurring accruals, necessary for a fair presentation thereof. The operating results for any quarter are not necessarily indicative of the results for any future periods.

(1)

The fourth quarter of 2016 includes out of period adjustments of $5.6 million for costs of services that were understated in prior quarters. As a result, the fourth quarter of 2016 costs of services are overstated by $5.6 million and gross profit, net income and diluted earnings per common share are understated by $5.6 million, $3.4 million and $0.06, respectively. Prior periods were not revised, as the impact on prior periods is immaterial. These adjustments were the cumulative effect of the immaterial misstatements spanning the previous six quarters. Of the total adjustments, $2.8 million related to 2015.

17. Subsequent Events

On February 21, 2017, the Company’s credit facility was amended whereby the interest rate for the term B loan was reduced by 50 basis points and the revolving credit facility was increased to $200.0 million, with its maturity date extended to February 21, 2022. The maturity date for the term B loan remains at June 5, 2022.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of On Assignment, Inc.

Calabasas, California

We have audited the internal control over financial reporting of On Assignment, Inc. and subsidiaries (the "Company") as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 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 and financial statement schedule as of and for the year ended December 31, 2016 of the Company and our report dated March 1, 2017 expressed an unqualified opinion on those financial statements and financial statement schedule.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report on Form 10-K, our management carried out an evaluation, under the supervision and with the participation of our Principal Executive Officer and Principal Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). Based on this evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that our disclosure controls and procedures are effective as of the end of the period covered by this report. The term “disclosure controls and procedures” means controls and other procedures of the Company that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. “Disclosure controls and procedures” include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive 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

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) for the Company. The term “internal control over financial reporting” is defined as a process designed by, or under the supervision of, our Principal Executive and Principal Financial Officers, or persons performing similar functions and effected by our 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 and includes those policies and procedures that:


•	Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;


•	Provide reasonable assurance that the 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


•	Provide reasonable assurance regarding prevention of 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 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 risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Management, under the supervision and with the participation of our Principal Executive Officer and Principal Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2016. In making this assessment, management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013). Based on our assessment and those criteria, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2016. Our independent registered public accounting firm, Deloitte & Touche LLP, has included an attestation report on our internal control over financial reporting, which is included above.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the Company’s fourth quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
