NISOURCE INC.
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of NiSource Inc.
Merrillville, Indiana

We have audited the accompanying consolidated balance sheets of NiSource Inc. and subsidiaries (the “Company”) as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, common 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 the 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 NiSource 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.
As discussed in Note 3 to the consolidated financial statements, on July 1, 2015 the Company completed the spin-off of its subsidiary Columbia Pipeline Group, Inc.
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 February 22, 2017 expressed an unqualified opinion on the Company’s internal control over financial reporting.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

NISOURCE INC.
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of NiSource Inc.
Merrillville, Indiana

We have audited the internal control over financial reporting of NiSource Inc. and subsidiaries (the "Company") as of December 31, 2016, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 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 February 22, 2017 expressed an unqualified opinion on those financial statements and financial statement schedule and included an explanatory paragraph related to the Company’s spin-off of its subsidiary Columbia Pipeline Group, Inc. on July 1, 2015.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)


1.
Nature of Operations and Summary of Significant Accounting Policies

A.       Company Structure and Principles of Consolidation.  NiSource, a Delaware corporation headquartered in Merrillville, Indiana, is an energy holding company whose subsidiaries are fully regulated natural gas and electric utility companies serving approximately 3.9 million customers in seven states. NiSource generates substantially all of its operating income through these rate-regulated businesses. The consolidated financial statements include the accounts of NiSource and its majority-owned subsidiaries after the elimination of all intercompany accounts and transactions.
B.       Use of Estimates.    The preparation of financial statements in conformity with GAAP 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.
C.       Cash, Cash Equivalents and Restricted Cash.    NiSource considers all highly liquid investments with original maturities of three months or less to be cash equivalents. NiSource reports amounts deposited in brokerage accounts for margin requirements as restricted cash. In addition, NiSource has amounts deposited in trust to satisfy requirements for the provision of various property, liability, workers compensation, and long-term disability insurance, which is classified as restricted cash and disclosed as an investing cash flow on the Statements of Consolidated Cash Flows.
D. Accounts Receivable and Unbilled Revenue.    Accounts receivable on the Consolidated Balance Sheets includes both billed and unbilled amounts. Unbilled amounts of accounts receivable relate to a portion of a customer’s consumption of gas or electricity from the date of the last cycle billing date through the last day of the month (balance sheet date). Factors taken into consideration when estimating unbilled revenue include historical usage, customer rates and weather. Accounts receivable fluctuates from year to year depending in large part on weather impacts and price volatility. NiSource's accounts receivable on the Consolidated Balance Sheets include unbilled revenue, less reserves, in the amounts of $329.7 million and $237.1 million as of December 31, 2016 and 2015, respectively. The reserve for uncollectible receivables is the Company’s best estimate of the amount of probable credit losses in the existing accounts receivable. The Company determined the reserve based on historical experience and in consideration of current market conditions. Account balances are charged against the allowance when it is anticipated the receivable will not be recovered.
E.        Investments in Debt Securities.    NiSource’s investments in debt securities are carried at fair value and are designated as available-for-sale. These investments are included within “Other investments” on the Consolidated Balance Sheets. Unrealized gains and losses, net of deferred income taxes, are reflected as accumulated other comprehensive income (loss). These investments are monitored for other than temporary declines in market value. Realized gains and losses and permanent impairments are reflected in the Statements of Consolidated Income. No material impairment charges were recorded for the years ended December 31, 2016, 2015 or 2014. Refer to Note 16, "Fair Value," for additional information.
F.        Basis of Accounting for Rate-Regulated Subsidiaries.    Rate-regulated subsidiaries account for and report assets and liabilities consistent with the economic effect of the way in which regulators establish rates, if the rates established are designed to recover the costs of providing the regulated service and it is probable that such rates can be charged and collected. Certain expenses and credits subject to utility regulation or rate determination normally reflected in income are deferred on the Consolidated Balance Sheets and are recognized in income as the related amounts are included in customer rates and recovered from or refunded to customers.
In the event that regulation significantly changes the opportunity for NiSource to recover its costs in the future, all or a portion of NiSource’s regulated operations may no longer meet the criteria for regulatory accounting. In such an event, a write-down of all or a portion of NiSource’s existing regulatory assets and liabilities could result. If transition cost recovery was approved by the appropriate regulatory bodies that would meet the requirements under GAAP for continued accounting as regulatory assets and liabilities during such recovery period, the regulatory assets and liabilities would be reported at the recoverable amounts. If unable to continue to apply the provisions of regulatory accounting, NiSource would be required to apply the provisions of ASC 980-20, Discontinuation of Rate-Regulated Accounting. In management’s opinion, NiSource’s regulated subsidiaries will be subject to regulatory accounting for the foreseeable future. Refer to Note 8, "Regulatory Matters," for additional information.
G.       Plant and Other Property and Related Depreciation and Maintenance.    Property, plant and equipment (principally utility plant) is stated at cost. The rate-regulated subsidiaries record depreciation using composite rates on a straight-line basis over the remaining service lives of the electric, gas and common properties as approved by the appropriate regulators.

16

NISOURCE INC.
Notes to Consolidated Financial Statements

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

Non-utility property is generally depreciated on a straight-line basis over the life of the associated asset. Refer to Note 5, "Property, Plant and Equipment," for additional information related to depreciation expense at Units 7 and 8 at Bailly Generating Station.
For rate-regulated companies, AFUDC is capitalized on all classes of property except organization costs, land, autos, office equipment, tools and other general property purchases. The allowance is applied to construction costs for that period of time between the date of the expenditure and the date on which such project is placed in service. The pre-tax rate for AFUDC was 4.5% in 2016, 4.7% in 2015 and 4.5% in 2014.
Generally, NiSource’s subsidiaries follow the practice of charging maintenance and repairs, including the cost of removal of minor items of property, to expense as incurred. When NiSource’s subsidiaries retire regulated property, plant and equipment, original cost plus the cost of retirement, less salvage value, is charged to accumulated depreciation. However, when it becomes probable a regulated asset will be retired substantially in advance of its original expected useful life or is abandoned, the cost of the asset and the corresponding accumulated depreciation is recognized as a separate asset. If the asset is still in operation, the net amount is classified as "Other property, at cost, less accumulated depreciation" on the Consolidated Balance Sheets. If the asset is no longer operating, the net amount is classified in "Regulatory assets" on the Consolidated Balance Sheets. If NiSource is able to recover a full return on investment, the carrying value of the asset is based on historical cost. If NiSource is not able to recover a full return on investment, a loss on impairment is recognized to the extent the net book value of the asset exceeds the present value of future revenues discounted at the incremental borrowing rate.

When NiSource’s subsidiaries sell entire regulated operating units, or retire or sell nonregulated properties, the original cost and accumulated depreciation and amortization balances are removed from "Property, Plant and Equipment" on the Consolidated Balance Sheets. Any gain or loss is recorded in earnings, unless otherwise required by the applicable regulatory body. Refer to Note 5, "Property, Plant and Equipment," for further information.
External and internal costs associated with computer software developed for internal use are capitalized. Capitalization of such costs commences upon the completion of the preliminary stage of each project. Once the installed software is ready for its intended use, such capitalized costs are amortized on a straight-line basis generally over a period of five years, except for certain significant enterprise-wide technology investments which are amortized over a ten-year period.
H.        Goodwill and Other Intangible Assets.    Substantially all of NiSource's goodwill relates to the excess of cost over the fair value of the net assets acquired in the Columbia acquisition on November 1, 2000. NiSource tests its goodwill for impairment annually as of May 1st, or more frequently if events and circumstances indicate that goodwill might be impaired. Fair value of NiSource's reporting units is determined using a combination of income and market approaches.
NiSource has other intangible assets consisting primarily of franchise rights apart from goodwill that were identified as part of the purchase price allocations associated with the acquisition of Columbia of Massachusetts which is being amortized on a straight-line basis over forty years from the date of acquisition. See Note 6, "Goodwill and Other Intangible Assets," for additional information.
I.        Revenue Recognition.    Revenue is recorded as products and services are delivered. Utility revenues are billed to customers monthly on a cycle basis. Revenues are recorded on the accrual basis and also include estimates for electricity and gas delivered but not billed. The accruals for unbilled revenues are reversed in the subsequent accounting period when meters are actually read and customers are billed.
On occasion, NiSource's regulated subsidiaries are permitted to implement new rates that have not been formally approved by their state regulatory commissions, which are subject to refund. As permitted by accounting principles generally accepted in the United States, each regulated subsidiary recognizes this revenue and establishes a reserve for amounts that could be refunded based on its experience for the jurisdiction in which the rates were implemented. In connection with such revenues, estimated rate refund liabilities are recorded which reflect management’s current judgment of the ultimate outcomes of the proceedings. No provisions are made when, in the opinion of management, the facts and circumstances preclude a reasonable estimate of the outcome.
J.        Accounts Receivable Transfer Program.    Certain of NiSource’s subsidiaries have agreements with third parties to sell certain accounts receivable without recourse. These transfers of accounts receivable are accounted for as secured borrowings. The entire gross receivables balance remains on the December 31, 2016 and 2015 Consolidated Balance Sheets and short-term debt is recorded in the amount of proceeds received from the purchasers involved in the transactions. Refer to Note 17, "Transfers of Financial Assets," for further information.

Notes to Consolidated Financial Statements

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

K.        Gas Cost and Fuel Adjustment Clause.    NiSource’s regulated subsidiaries defer most differences between gas and fuel purchase costs and the recovery of such costs in revenues, and adjust future billings for such deferrals on a basis consistent with applicable state-approved tariff provisions. These deferred balances are recorded as regulatory assets or regulatory liabilities, as appropriate, on the Consolidated Balance Sheets. Refer to Note 8, "Regulatory Matters," for additional information.
L.        Inventory.    Both the LIFO inventory methodology and the weighted average cost methodology are used to value natural gas in storage, as approved by regulators for all of NiSource’s regulated subsidiaries. Inventory valued using LIFO was $46.1 million and $50.2 million at December 31, 2016 and 2015, respectively. Based on the average cost of gas using the LIFO method, the estimated replacement cost of gas in storage was less than the stated LIFO cost by $9.4 million and $27.2 million at December 31, 2016 and 2015, respectively. Gas inventory valued using the weighted average cost methodology was $233.8 million at December 31, 2016 and $293.3 million at December 31, 2015.
Electric production fuel is valued using the weighted average cost inventory methodology, as approved by NIPSCO's regulator. Electric production fuel balances were $112.8 million at December 31, 2016 and $106.3 million at December 31, 2015.
Materials and supplies are valued using the weighted average cost inventory methodology. Materials and supplies balances were $101.7 million at December 31, 2016 and $86.8 million at December 31, 2015.
M.        Accounting for Exchange and Balancing Arrangements of Natural Gas.    NiSource’s Gas Distribution Operations segment enters into balancing and exchange arrangements of natural gas as part of its operations and off-system sales programs. NiSource records a receivable or payable for any of its respective cumulative gas imbalances, as well as for any gas inventory borrowed or lent under a Gas Distributions Operations exchange agreement. These receivables and payables are recorded as “Exchange gas receivable” or “Exchange gas payable” on NiSource’s Consolidated Balance Sheets, as appropriate.
N.         Accounting for Risk Management Activities.    NiSource accounts for its derivatives and hedging activities in accordance with ASC 815. NiSource recognizes all derivatives as either assets or liabilities on the Consolidated Balance Sheets at fair value, unless such contracts are exempted as a normal purchase normal sale under the provisions of the standard. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and resulting designation.

NiSource has elected not to net fair value amounts for any of its derivative instruments or the fair value amounts recognized for its right to receive cash collateral or obligation to pay cash collateral arising from those derivative instruments recognized at fair value, which are executed with the same counterparty under a master netting arrangement. See Note 9, "Risk Management Activities," for additional information.

O.        Income Taxes and Investment Tax Credits.    NiSource records income taxes to recognize full interperiod tax allocations. Under the asset and liability method, deferred income taxes are provided for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amount and the tax basis of existing assets and liabilities. Previously recorded investment tax credits of the regulated subsidiaries were deferred on the balance sheet and are being amortized to book income over the regulatory life of the related properties to conform to regulatory policy.
To the extent certain deferred income taxes of the regulated companies are recoverable or payable through future rates, regulatory assets and liabilities have been established. Regulatory assets for income taxes are primarily attributable to property-related tax timing differences for which deferred taxes had not been provided in the past, when regulators did not recognize such taxes as costs in the ratemaking process. Regulatory liabilities for income taxes are primarily attributable to the regulated companies’ obligation to refund to ratepayers deferred income taxes provided at rates higher than the current Federal income tax rate. Such amounts are credited to ratepayers using either the average rate assumption method or the reverse South Georgia method.
Pursuant to the U.S. Internal Revenue Code and relevant state taxing authorities, NiSource and its subsidiaries file consolidated income tax returns for Federal and certain state jurisdictions. NiSource and its subsidiaries are parties to an agreement (the “Intercompany Income Tax Allocation Agreement”) that provides for the allocation of consolidated tax liabilities. The Intercompany Income Tax Allocation Agreement generally provides that each party is allocated an amount of tax similar to that which would be owed had the party been separately subject to tax.
P.       Environmental Expenditures.    NiSource accrues for costs associated with environmental remediation obligations when the incurrence of such costs is probable and the amounts can be reasonably estimated, regardless of when the expenditures are actually made. The undiscounted estimated future expenditures are based on currently enacted laws and regulations, existing

technology and estimated site-specific costs where assumptions may be made about the nature and extent of site contamination, the extent of cleanup efforts, costs of alternative cleanup methods and other variables. The liability is adjusted as further information is discovered or circumstances change. The reserves for estimated environmental expenditures are recorded on the Consolidated Balance Sheets in “Legal and environmental” for short-term portions of these liabilities and “Other noncurrent liabilities” for the respective long-term portions of these liabilities. Rate-regulated subsidiaries applying regulatory accounting establish regulatory assets on the Consolidated Balance Sheets to the extent that future recovery of environmental remediation costs is probable through the regulatory process. Refer to Note 18, "Other Commitments and Contingencies," for further information.
Q.        Excise Taxes.   NiSource accounts for excise taxes that are customer liabilities by separately stating on its invoices the tax to its customers and recording amounts invoiced as liabilities payable to the applicable taxing jurisdiction. Such balances are presented within "Other accruals" on the Consolidated Balance Sheets. These types of taxes collected from customers, comprised largely of sales taxes, are presented on a net basis affecting neither revenues nor cost of sales. NiSource accounts for excise taxes for which it is liable by recording a liability for the expected tax with a corresponding charge to “Other taxes” expense on the Statements of Consolidated Income.
R.        Accrued Insurance Liabilities. NiSource accrues for insurance costs related to workers compensation, automobile, property, general and employment practices liabilities based on the most probable value of each claim. Claim values are determined by professional, licensed loss adjusters who consider the facts of the claim, anticipated indemnification and legal expenses, and respective state rules. Claims are reviewed by NiSource at least quarterly and an adjustment is made to the accrual based on the most current information. NiSource’s actual exposure to liability is minimal due to coverage from its wholly-owned captive insurer who then re-insures risk to third party insurance providers for the majority of costs paid to claimants above NiSource's deductible.

NiSource is currently evaluating the impact of certain ASUs on its Consolidated Financial Statements or Notes to Consolidated Financial Statements, which are described below:
Standard
Description
Effective date
Effect on the financial statements or other significant matters
ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment
The pronouncement simplifies the calculation of goodwill impairment charges by eliminating the the requirement to perform the "Step 2" analysis when the "Step 1" test is failed.
Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for annual or interim periods beginning after January 1, 2017.
NiSource elected to adopt this ASU effective January 1, 2017. The adoption of this standard did not have a material impact on the Consolidated Financial Statements or Notes to Consolidated Financial Statements.
ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)
The pronouncement provides clarification on the classification and presentation of restricted cash in the Statements of Consolidated Cash Flows.
Annual periods beginning after December 15, 2017, including interim periods therein. Early adoption is permitted.
Upon adoption, restricted cash on the Statements of Consolidated Cash Flows will no longer be presented as an investing activity and will instead be included as a component of beginning and ending cash. NiSource expects to adopt this ASU effective January 1, 2018.


ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)
The pronouncement provides specific guidance on eight cash flow classification issues to reduce the diversity in practice.

Annual periods beginning after December 15, 2017, including interim periods therein. Early adoption is permitted.
NiSource does not anticipate the adoption of this standard will have a material impact on the Consolidated Financial Statements or Notes to Consolidated Financial Statements. NiSource expects to adopt this ASU effective January 1, 2018.

Description
Effective date
Effect on the financial statements or other significant matters
ASU 2016-13, Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

The pronouncement changes the impairment model for most financial assets, replacing the current "incurred loss" model. ASU 2016-13 will require the use of an "expected loss" model for instruments measured at amortized cost and will also require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount.
Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for annual or interim periods beginning after December 15, 2018.
NiSource is currently evaluating the impact of adoption, if any, on the Consolidated Financial Statements and Notes to Consolidated Financial Statements.
ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients

The pronouncement clarifies implementation guidance in ASU 2014-09 on assessing collectability, noncash consideration and the presentation of sales and other similar taxes collected from customers.

Annual periods beginning after December 15, 2017, including interim periods therein. Early adoption is permitted for annual or interim periods beginning after December 15, 2016.
NiSource has formed an internal stakeholder group to promote information sharing and communication of the new requirements. Additionally, NiSource participates in an informal forum of industry peers where questions can be asked and interpretations of the new standard can be shared. NiSource has separated its various revenue streams into high-level categories, which will serve as the basis for accounting analysis and documentation as it relates to the pronouncement's impact on NiSource's revenues. Substantially all of NiSource’s revenues are tariff based, which NiSource believes will be in scope of ASC 606. NiSource expects to adopt this ASU effective January 1, 2018. As of December 31, 2016, NiSource has not concluded on a method of adoption.
ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations
The pronouncement clarifies the principal versus agent guidance in ASU 2014-09. The amendment clarifies how an entity should identify the unit of accounting for the principal versus agent evaluation, and how it should apply the control principle to certain types of arrangements.


ASU 2014-09, Revenue from Contracts with Customers (Topic 606)
The pronouncement outlines a single, comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The core principle of the new standard is that an entity should recognize revenue to depict the transfer of 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.
ASU 2016-02, Leases (Topic 842)
The pronouncement introduces a lessee model that brings most leases on the balance sheet. The standard requires that lessees recognize the following for all leases (with the exception of short-term leases, as that term is defined in the standard) at the lease commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.

Annual periods beginning after December 15, 2018, including interim periods therein. Early adoption is permitted.
NiSource has formed an internal stakeholder group that meets periodically to share information and gather data related to leasing activity at NiSource. This includes compiling a list of all contracts that could meet the definition of a lease under the new standard and evaluating the accounting for these contracts under the new standard to determine the ultimate impact the new standard will have on NiSource’s financial statements. Also this procedure has identified process improvements to ensure data from newly initiated leases is captured to comply with the new standard. This work is ongoing with the assistance of a third-party advisory firm. As of December 31, 2016, no conclusion has been reached as to when NiSource will adopt this standard.
  
ASU 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities
The pronouncement makes limited amendments to the guidance in GAAP on the classification and measurement of financial instruments. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicability exception.
Annual periods beginning after December 15, 2017, including interim periods therein. Early adoption is permitted.
NiSource is currently evaluating the impact of adoption, if any, on the Consolidated Financial Statements and Notes to Consolidated Financial Statements.

The table below includes ASUs NiSource adopted during 2016:
Standard
Adoption
ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting
NiSource elected to adopt this pronouncement during the third quarter of 2016. Upon adoption, NiSource elected to begin accounting for forfeitures of share-based awards as they occur. The impact of this change was not material. Additionally, NiSource recorded a $25.3 million credit to beginning retained deficit. This adjustment represents excess tax benefits generated in years prior to 2016 that were previously not recognized in stockholders' equity due to NOLs in those years. Both of these adjustments were adopted on a modified retrospective basis. Lastly, NiSource recorded income tax benefits of $7.2 million related to excess tax benefits generated in 2016. This provision was adopted on a prospective basis. However, because NiSource adopted the standard during an interim period, the standard required this $7.2 million benefit be reflected as though it was adopted as of January 1, 2016.

3.    Discontinued Operations
On July 1, 2015, NiSource completed the Separation through a special pro rata stock dividend, distributing one share of CPG common stock for every one share of NiSource common stock held by any NiSource stockholder on June 19, 2015, the record date. The Separation resulted in two stand-alone energy infrastructure companies: NiSource, a fully regulated natural gas and electric utilities company, and CPG, a natural gas pipeline, midstream and storage company. As a stand-alone company, on the date of the Separation, CPG's operations consisted of NiSource's Columbia Pipeline Group Operations segment prior to the Separation. Following the Separation, NiSource retained no ownership interest in CPG. On the date of the Separation, CPG consisted of approximately $9.2 billion of assets, $5.6 billion of liabilities and $3.6 billion of equity.
The results of operations and cash flows for the former Columbia Pipeline Group Operations segment have been reported as discontinued operations for all periods presented. Additionally, the assets and liabilities of the former Columbia Pipeline Group Operations segment were reclassified as assets and liabilities of discontinued operations for all prior periods.
During 2016, NiSource recorded a $3.6 million tax benefit resulting from favorable estimate-to-actual adjustments related to non-deductible costs from the Separation. There were no other material results from discontinued operations during 2016.
Results from discontinued operations are provided in the following table. These results are primarily from NiSource's former Columbia Pipeline Group Operations segment.

CPG’s financing requirements prior to the private placement of senior notes on May 22, 2015 were satisfied through borrowings from NiSource Finance. Interest expense from discontinued operations primarily represents net interest charged to CPG from NiSource Finance, less AFUDC. Subsequent to May 22, 2015, interest expense from discontinued operations also includes interest incurred on CPG’s private placement of $2,750.0 million of senior notes.
Continuing Involvement
Natural gas transportation and storage services provided to NiSource by CPG were $150.5 million, $147.6 million and $146.2 million for the years ended December 31, 2016, 2015 and 2014, respectively. Prior to July 1, 2015, these costs were eliminated in consolidation. Beginning July 1, 2015, these costs and associated cash flows represent third-party transactions with CPG and are not eliminated in consolidation, as such services have continued subsequent to the Separation and are expected to continue for the foreseeable future.
As a result of the Separation, NiSource and CPG entered into Transition Services Agreements ("TSAs"). NiSource expects the TSAs to terminate within 24 months from the date of the Separation. The TSAs set forth the terms and conditions for NiSource and CPG to provide certain transition services to one another. Under the TSAs, NiSource provides CPG certain information technology, financial and accounting, human resource and other specified services. For the period July 1, 2015 to December 31, 2015 and for the year ended December 31, 2016, the amounts NiSource billed CPG for these services were immaterial.
There were no material assets and liabilities of discontinued operations on the Consolidated Balance Sheets at December 31, 2016 and 2015.

6.
Goodwill and Other Intangible Assets

Goodwill. Substantially all of NiSource's goodwill relates to the excess of cost over the fair value of the net assets acquired in the Columbia acquisition on November 1, 2000. The following presents NiSource's goodwill balance allocated by segment as of December 31, 2016:

NiSource completed a quantitative ("step 1") fair value measurement of its reporting units during the May 1, 2016 goodwill test. The test indicated that the fair value of each of the reporting units that are allocated goodwill exceeded their carrying values, indicating that no impairment was necessary.
Intangible Assets. NiSource's intangible assets, apart from goodwill, consist of franchise rights. Franchise rights were identified as part of the purchase price allocations associated with the acquisition in February 1999 of Columbia of Massachusetts. These amounts were $242.7 million and $253.7 million, net of accumulated amortization of $199.5 million and $188.5 million, at December 31, 2016 and 2015, respectively, and are being amortized on a straight-line basis over forty years from the date of acquisition through 2039. NiSource recorded amortization expense of $11.0 million in 2016, 2015, and 2014 related to its franchise right intangible asset.
7.
Asset Retirement Obligations

NiSource has recognized asset retirement obligations associated with various legal obligations including costs to remove and dispose of certain construction materials located within many of NiSource’s facilities, certain costs to retire pipeline, removal costs for certain underground storage tanks, removal of certain pipelines known to contain PCB contamination, closure costs for certain sites including ash ponds, solid waste management units and a landfill, as well as some other nominal asset retirement obligations. NiSource has a significant obligation associated with the decommissioning of its two hydro facilities located in Indiana. These hydro facilities have an indeterminate life, and as such, no asset retirement obligation has been recorded.

See Note 18-D, "Environmental Matters," for additional information on CCRs.
(2)The change in estimated cash flows for 2015 primarily represents estimated costs associated with the EPA's final rule for regulation of CCRs and changes to cost estimates for certain solid waste management units. See Note 18-D, "Environmental Matters," for additional information on CCRs.
Certain non-legal costs of removal that have been, and continue to be, included in depreciation rates and collected in the customer rates of the rate-regulated subsidiaries are classified as "Regulatory liabilities" on the Consolidated Balance Sheets.

Regulatory Matters
Regulatory Assets and Liabilities

NiSource follows the accounting and reporting requirements of ASC Topic 980, which provides that regulated entities account for and report assets and liabilities consistent with the economic effect of regulatory rate-making procedures if the rates established are designed to recover the costs of providing the regulated service and it is probable that such rates can be charged and collected. Certain expenses and credits subject to utility regulation or rate determination normally reflected in income or expense are deferred on the balance sheet and are recognized in the income statement as the related amounts are included in customer rates and recovered from or refunded to customers.

Regulatory assets, including underrecovered gas and fuel cost, of approximately $1,708.2 million as of December 31, 2016 are not earning a return on investment. Regulatory assets of approximately $1,561.9 million include expenses that are recovered as components of the cost of service and are covered by regulatory orders. These costs are recovered over a remaining life of up to 41 years. Regulatory assets of approximately $323.5 million at December 31, 2016, require specific rate action.
As noted below, regulatory assets for which costs have been incurred are included (or expected to be included, for costs incurred subsequent to the most recently approved rate case) in certain companies’ rate base, thereby providing a return on invested costs. Certain regulatory assets do not result from cash expenditures and therefore do not represent investments included in rate base or have offsetting liabilities that reduce rate base.

Unrecognized pension benefit and other postretirement benefit costs – In 2007, NiSource adopted certain updates of ASC 715 which required, among other things, the recognition in other comprehensive income or loss of the actuarial gains or losses and the prior service costs or credits that arise during the period but that are not immediately recognized as components of net periodic benefit costs. Certain subsidiaries defer these gains or losses as a regulatory asset in accordance with regulatory orders or as a result of regulatory precedent, to be recovered through base rates.
Other postretirement costs – Primarily relates to the difference between postretirement expense recorded by certain subsidiaries due to regulatory orders and the postretirement expense recorded in accordance with GAAP. These costs are expected to be collected through future base rates, revenue riders or tracking mechanisms.
Environmental costs – Includes certain recoverable costs of investigating, testing, remediating and other costs related to gas plant sites, disposal sites or other sites onto which material may have migrated. Certain companies defer the costs as a regulatory asset in accordance with regulatory orders, to be recovered in future base rates, billing riders or tracking mechanisms.
Regulatory effects of accounting for income taxes – Represents the deferral and under collection of deferred taxes in the rate making process. In prior years, NiSource has lowered customer rates in certain jurisdictions for the benefits of accelerated tax deductions. Amounts are expensed for financial reporting purposes as NiSource recovers deferred taxes in the rate making process.
Underrecovered gas and fuel costs – Represents the difference between the costs of gas and fuel and the recovery of such costs in revenue and is used to adjust future billings for such deferrals on a basis consistent with applicable state-approved tariff provisions. Recovery of these costs is achieved through tracking mechanisms.
Depreciation – Primarily relates to the difference between the depreciation expense recorded by Columbia of Ohio due to a regulatory order and the depreciation expense recorded in accordance with GAAP. The regulatory asset is currently being amortized over the life of the assets. Also included is depreciation associated with the Columbia of Ohio IRP and capital expenditure program. Recovery of these costs is achieved through base rates and rider mechanisms.
In 2005, the PUCO authorized Columbia of Ohio to revise its depreciation accrual rates for the period beginning January 1, 2005. The revised depreciation rates are now higher than those which would have been utilized if Columbia of Ohio were not subject to regulation. The amount of depreciation that would have been recorded for 2005 through 2016 had Columbia of Ohio not been subject to rate regulation is a combined $638.0 million, $74.1 million less than the $712.1 million reflected in rates. The regulatory asset was $57.6 million and $65.3 million as of December 31, 2016 and 2015, respectively. The amount of depreciation that would

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

have been recorded for 2016 had Columbia of Ohio not been subject to rate regulation is $78.2 million, $7.7 million less than the $85.9 million reflected in rates.
Columbia of Ohio also has PUCO approval to defer depreciation associated with its IRP and capital expenditure program. As of December 31, 2016, depreciation of $23.4 million and $31.8 million was deferred for the respective programs. Recovery of the IRP depreciation is approved annually through the IRP rider. The equivalent of annual depreciation expense, based on the average life of the related assets, is included in the calculation of the IRP rider approved by the PUCO and billed to customers. Deferred depreciation expense is recognized as the IRP rider is billed to customers. The recovery mechanism for depreciation associated with the capital expenditure program will be addressed in a separate rate proceeding.
Uncollectible accounts receivable deferred for future recovery – Represents the difference between certain uncollectible expenses and the recovery of such costs to be collected through cost tracking mechanisms in accordance with regulatory orders.
Post-in-service carrying charges – Columbia of Ohio has approval from the PUCO by regulatory order to defer debt-based carrying charges as a regulatory asset for future recovery. Columbia of Ohio defers this carrying charge on eligible property, plant and equipment from the time it is placed into utility service until recovery of the property, plant and equipment is included in customer rates in base rates or through a rider mechanism. Inclusion in customer rates generally occurs when Columbia of Ohio files its next rate proceeding following the in-service date of the property, plant and equipment.
EERM operation and maintenance and depreciation deferral – NIPSCO obtained approval from the IURC to recover certain environmental related costs including operation and maintenance and depreciation expense once the environmental facilities become operational. Recovery of these costs will continue until such assets are included in rate base through an electric base rate case. The EERM deferred charges represent expenses that will be recovered from customers through an annual EERM Cost Tracker which authorizes the collection of deferred balances over a six month period.
Sugar Creek carrying charges and deferred depreciation – The IURC approved the deferral of debt-based carrying charges and the deferral of depreciation expense for the Sugar Creek assets. Balances are being amortized over seven years with new rates implemented on October 1, 2016.
TDSIC - NIPSCO obtained approval from the IURC to recover costs for certain system modernization projects outside of a base rate proceeding. Eighty percent of the related costs, including depreciation, property taxes, and debt and equity based carrying charges are recovered through a semi-annual recovery mechanism. Recovery of these costs will continue until such assets are included in rate base through a gas or electric rate case, respectively. The remaining twenty percent of the costs are deferred until the next rate case which includes a twenty percent deferral of the return on capital. Equity based carrying charges and the equity component of return on capital are not reflected in the regulatory asset balance at December 31, 2016.
Safety Activity Costs - Represents the difference between costs incurred in eligible safety programs in excess of those being recovered in rates. The eligible cost deferrals represent necessary business expenses incurred in compliance with PHMSA regulations and are targeted to enhance the safety of the pipeline systems. Certain subsidiaries defer the excess costs as a regulatory asset in accordance with regulatory orders and recovery of these costs will be address in future base rate proceedings.
DSM Program - Represents costs associated with Gas Distribution Operations and Electric Operations companies' energy efficiency and conservation programs. Costs are recovered through tracking mechanisms.
 Liabilities:
Overrecovered gas and fuel costs – Represents the difference between the cost of gas and fuel and the recovery of such costs in revenues, and is the basis to adjust future billings for such refunds on a basis consistent with applicable state-approved tariff provisions. Refunding of these revenues is achieved through tracking mechanisms.
Cost of removal – Represents anticipated costs of removal that have been, and continue to be, included in depreciation rates and collected in customer rates of the rate-regulated subsidiaries for future costs to be incurred.
Regulatory effects of accounting for income taxes – Represents amounts owed to customers for deferred taxes collected at a higher rate than the current statutory rates and liabilities associated with accelerated tax deductions owed to customers that are established during the rate making process.
Other postretirement costs – Primarily represents cash contributions in excess of postretirement benefit expense that is deferred as a regulatory liability by certain subsidiaries in accordance with regulatory orders.

Gas Distribution Operations Regulatory Matters
Cost Recovery and Trackers. Comparability of Gas Distribution Operations line item operating results is impacted by regulatory trackers that allow for the recovery in rates of certain costs such as those described below. Increases in the expenses that are the subject of trackers result in a corresponding increase in net revenues and therefore have essentially no impact on total operating income results.
Certain operating costs of the NiSource distribution companies are significant, recurring in nature, and generally outside the control of the distribution companies. Some states allow the recovery of such costs through cost tracking mechanisms. Such tracking mechanisms allow for abbreviated regulatory proceedings in order for the distribution companies to implement charges and recover appropriate costs. Tracking mechanisms allow for more timely recovery of such costs as compared with more traditional cost recovery mechanisms. Examples of such mechanisms include GCR adjustment mechanisms, tax riders, and bad debt recovery mechanisms.
A portion of the distribution companies' revenue is related to the recovery of gas costs, the review and recovery of which occurs through standard regulatory proceedings. All states in NiSource's operating area require periodic review of actual gas procurement activity to determine prudence and to permit the recovery of prudently incurred costs related to the supply of gas for customers. NiSource distribution companies have historically been found prudent in the procurement of gas supplies to serve customers.
Certain of the NiSource distribution companies have completed rate proceedings involving infrastructure replacement or are embarking upon regulatory initiatives to replace significant portions of their operating systems that are nearing the end of their useful lives. Each LDC's approach to cost recovery may be unique, given the different laws, regulations and precedent that exist in each jurisdiction.
Columbia of Ohio. On November 28, 2012, the PUCO approved Columbia of Ohio’s application to extend its Infrastructure Replacement Program for an additional five years (2013-2017), allowing Columbia of Ohio to continue to invest and recover on its accelerated main replacements. Columbia of Ohio last filed its application to adjust rates associated with its IRP and DSM Riders on February 26, 2016, which requested authority to increase revenues by $25.9 million. On April 20, 2016, the PUCO issued an order approving Columbia of Ohio’s application with rates going into effect April 30, 2016. On November 28, 2016, Columbia of Ohio filed its notice of intent to file an application to adjust rates associated with its IRP and DSM riders. The notice of intent states that Columbia of Ohio will file an application by February 28, 2017, in which it will request authority to increase revenues by up to $33.5 million.
On December 27, 2016, Columbia of Ohio filed its Notice of Intent to file an application that will request authority for Columbia of Ohio to extend its IRP for an additional five years (2018-2022). Columbia of Ohio’s application will be filed in late February 2017.
On December 17, 2014, the PUCO approved Columbia of Ohio’s application to establish a regulatory asset and defer the expenditures to be incurred in implementing Columbia of Ohio’s Pipeline Safety Program. Columbia of Ohio requested authority to defer Pipeline Safety Program costs of up to $15 million annually. On March 11, 2016, Columbia of Ohio filed an application to increase the annual deferral authority from $15 million to $25 million. On June 24, 2016, Columbia of Ohio and PUCO staff filed a stipulation that recommended approval of the application in all material respects. On August 26, 2016, the PUCO approved the stipulation to increase the deferral authority to $25 million per year through January 1, 2024.
Columbia of Pennsylvania. On March 18, 2016, Columbia of Pennsylvania filed a base rate case with the Pennsylvania PUC, seeking a revenue increase of $55.3 million annually. The case was driven by Columbia of Pennsylvania’s ongoing capital investment program which exceeded $232.0 million in 2016, and is projected to exceed $267.0 million in 2017. This case was also driven by operation and maintenance expenditures related to employee training and compliance with pipeline safety regulations. Columbia of Pennsylvania's request for rate relief included the recovery of costs that will be incurred after the implementation of new rates, as authorized by the Pennsylvania General Assembly with the passage of Act 11 of 2012. On September 2, 2016, the parties to the case filed a joint petition for settlement which provides for an annual revenue increase of $35.0 million. On September 28, 2016, the assigned administrative law judge issued a recommended decision to approve the proposed settlement, without modification. An order approving the settlement was issued from the Pennsylvania PUC on October 27, 2016, and new rates went into effect on December 19, 2016.
NIPSCO Gas. On April 30, 2013, then Indiana Governor Pence signed Senate Enrolled Act 560, the TDSIC statute, into law. Among other provisions, this legislation provides for cost recovery outside of a base rate proceeding for new or replacement electric and gas transmission, distribution, and storage projects that a public utility undertakes for the purposes of safety, reliability, system

modernization, or economic development. Provisions of the TDSIC statute require that, among other things, requests for recovery include a seven-year plan of eligible investments. Once the plan is approved by the IURC, eighty percent of eligible costs can be recovered using a periodic rate adjustment mechanism. The cost recovery mechanism is referred to as a TDSIC mechanism. Recoverable costs include a return on, and of, the investment, including AFUDC, post-in-service carrying charges, operation and maintenance expenses, depreciation and property taxes. The remaining twenty percent of recoverable costs are to be deferred for future recovery in the public utility’s next general rate case. The periodic rate adjustment mechanism is capped at an annual increase of no more than two percent of total retail revenues. On December 28, 2016, the IURC issued an order on the seven-year plan (2014-2020) within TDSIC-5 approving NIPSCO’s updated estimate of TDSIC-eligible investments of $824 million. The order also included approval to begin recovery of $211.6 million of cumulative net capital spend through June 30, 2016. New rates went into effect on January 1, 2017.
Columbia of Massachusetts. On July 7, 2014, the Governor of Massachusetts signed into law Chapter 149 of the Acts of 2014, An Act Relative to Natural Gas Leaks (“the Act”). The Act authorizes natural gas distribution companies to file gas infrastructure replacement plans with the Massachusetts DPU to address the replacement of aging natural gas pipeline infrastructure. In addition, the Act provides that the Massachusetts DPU may, after review of the plans, allow the proposed estimated costs of the plan into rates as of May 1 of the subsequent year. Pursuant to the Act, on October 30, 2015, Columbia of Massachusetts filed its GSEP for the 2016 construction year (“2016 GSEP”). Columbia of Massachusetts proposed to recover an increment of $6.4 million for the costs associated with the replacement of eligible leak-prone infrastructure during the 2016 construction year for a cumulative proposed revenue requirement recovery of $9.0 million. Columbia of Massachusetts subsequently revised the cumulative proposed revenue requirement recovery to $8.2 million. The Massachusetts DPU approved the 2016 GSEP filing on April 29, 2016, with new rates effective May 1, 2016. On October 31, 2016, Columbia of Massachusetts filed its GSEP for the 2017 construction year. Columbia of Massachusetts is proposing to recover an incremental $8.1 million for a cumulative revenue requirement recovery of $16.8 million. An order is expected from the Massachusetts DPU in early 2017, with new rates effective May 1, 2017.
On October 30, 2009, the Massachusetts DPU approved Columbia of Massachusetts's revenue decoupling mechanism that was filed in its base rate case. This allows Columbia of Massachusetts to apply annual adjustments to its peak and off-peak rates. On March 16, 2016, Columbia of Massachusetts filed its 2016 off-peak period RDAF in the amount of $3.4 million. On April 28, 2016, the Massachusetts DPU approved the rate, which was effective May 1, 2016. On September 16, 2016, Columbia of Massachusetts filed its 2016-2017 peak period RDAF in the amount of $12.9 million. However, due to the implementation of the revenue cap included in the mechanism, $8.9 million is to be recovered starting November 1, 2016, with the remaining $4.0 million deferred until the 2017-2018 peak period RDAF. On October 31, 2016, the Massachusetts DPU approved the recovery of $8.9 million in rates effective November 1, 2016.
On April 16, 2015, Columbia of Massachusetts filed a base rate case with the Massachusetts DPU. The case, which sought increased annual revenues of approximately $49.0 million, was designed to support Columbia of Massachusetts's continued focus on providing safe and reliable service in compliance with increasing state and federal regulations and oversight, and recovery of associated increased operations and maintenance costs. Columbia of Massachusetts arrived at a settlement agreement with the Massachusetts Attorney General in the case which was filed for approval with the Massachusetts DPU on August 19, 2015 and approved on October 7, 2015. The settlement agreement provides for increased annual revenues of $32.8 million beginning November 1, 2015, with an additional $3.6 million annual increase in revenues starting November 1, 2016. The settlement also provides that Columbia of Massachusetts cannot increase base distribution rates to become effective prior to November 1, 2018.
Columbia of Virginia. On April 29, 2016, Columbia of Virginia filed a request with the VSCC, seeking an annual revenue increase of $37.0 million. The case is driven by Columbia of Virginia's ongoing capital program to modernize its infrastructure and to expand and upgrade its facilities to meet customer growth, as well as expenditures related to employee training and compliance with pipeline safety regulations. On September 28, 2016, Columbia of Virginia implemented updated interim base rates subject to refund. On January 17, 2017, Columbia of Virginia presented a stipulation and proposed recommendation, representing a settlement by all parties to the proceeding, that included a base revenue increase of $28.5 million. On February 8, 2017, the Hearing Examiner in the case filed a report recommending approval of the stipulation and proposed recommendation. A VSCC decision on the proposed recommendation is expected in the first half of 2017.
Columbia of Kentucky. On May 27, 2016, Columbia of Kentucky filed a base rate case with the Kentucky PSC, seeking an annual revenue increase of $25.4 million. This case was driven by Columbia of Kentucky's ongoing initiatives to improve the overall safety and reliability of its gas distribution system. On October 20, 2016, a settlement was reached which included an annual revenue increase of $13.4 million. On December 22, 2016, the Kentucky PSC issued an order modifying the stipulation, resulting

in an annual revenue increase of $13.1 million. Columbia of Kentucky accepted this modification, and rates went into effect on December 27, 2016.
Columbia of Maryland. On April 15, 2016, Columbia of Maryland filed a base rate case with the MPSC, seeking an annual revenue increase of $6.5 million. The case was driven by Columbia of Maryland’s ongoing capital investment program and by operations and maintenance expenditures related to compliance with pipeline safety regulations. On July 27, 2016, the parties to the case filed a joint petition for approval of a proposed settlement that includes an annual revenue increase of $3.7 million. On September 26, 2016, the assigned public utility law judge issued a proposed order approving the settlement without modification. There were no appeals to the administrative law judge's proposed order. As such, it became the order of the MPSC, and rates went into effect on October 27, 2016.
Electric Operations Regulatory Matters
Cost Recovery and Trackers. Comparability of Electric Operations line item operating results is impacted by regulatory trackers that allow for the recovery in rates of certain costs such as those described below. Increases in the expenses that are the subject of trackers result in a corresponding increase in net revenues and therefore have essentially no impact on total operating income results.
Certain operating costs of the Electric Operations are significant, recurring in nature, and generally outside the control of NIPSCO. The IURC allows for recovery of such costs through cost tracking mechanisms. Such tracking mechanisms allow for abbreviated regulatory proceedings in order for NIPSCO to implement charges and recover appropriate costs. Tracking mechanisms allow for more timely recovery of such costs as compared with more traditional cost recovery mechanisms. Examples of such mechanisms include electric energy efficiency programs, MISO non-fuel costs and revenues, resource capacity charges, and environmental related costs.
A portion of NIPSCO's revenue is related to the recovery of fuel costs to generate power and the fuel costs related to purchased power. These costs are recovered through a FAC, a quarterly, regulatory proceeding in Indiana.
NIPSCO has approval from the IURC to recover certain environmental related costs through an ECT. Under the ECT, NIPSCO is permitted to recover (1) AFUDC and a return on the capital investment expended by NIPSCO to implement environmental compliance plan projects and (2) related operation and maintenance and depreciation expenses once the environmental facilities become operational.
On October 26, 2016, the IURC issued an order on ECR-28 approving NIPSCO's request to begin earning a return on $267.0 million of cumulative net capital expenditures invested through June 30, 2016. Rates went into effect November 1, 2016.
On January 31, 2017, NIPSCO filed ECR-29 which included $261.1 million of net capital expenditures for the period ended December 31, 2016. An order is expected in the second quarter of 2017.
On October 1, 2015, NIPSCO filed an electric base rate case with the IURC, seeking a revenue increase of $126.6 million, before certain riders. As part of this filing, NIPSCO proposed to update base rates for previously incurred infrastructure improvements, revised depreciation rates and the inclusion of previously approved environmental and federally mandated compliance costs. On February 19, 2016, a stipulation and settlement agreement was filed with the IURC seeking a revenue increase of $72.5 million, before certain riders. On July 18, 2016, the IURC issued an order approving the settlement agreement as filed with new rates effective October 1, 2016.
NIPSCO received a final order from the IURC related to its original TDSIC plan as of January 16, 2016. That order authorized NIPSCO to defer, as a regulatory asset, 100% of all TDSIC costs incurred from March 1, 2014 through December 31, 2015 until such deferral is recovered as part of its next general rate case. As discussed above, the electric general rate case was approved on July 18, 2016, which allows for recovery in base rates of 100% of these previously incurred TDSIC costs. This approval allowed NIPSCO to record a regulatory asset of approximately $7.8 million in the third quarter of 2016.
On December 31, 2015, NIPSCO filed a new electric TDSIC seven-year plan of eligible investments for a total of approximately $1.3 billion covering spend in years 2016 through 2022. On March 24, 2016, a stipulation and settlement agreement was filed with the IURC which, among other things, sought approval of a seven-year plan that includes approximately $1.25 billion of investments eligible for ratemaking treatment. On July 12, 2016, the IURC issued an order approving the settlement agreement.
Consistent with the terms of the aforementioned electric TDSIC settlement agreement, NIPSCO made a TDSIC rate adjustment mechanism filing on June 30, 2016 seeking recovery and ratemaking relief associated with $45.5 million of cumulative net capital

expenditures invested through April 30, 2016. An IURC order approving NIPSCO's filing was received on January 25, 2017. New rates went into effect with the first billing cycle of February 2017.
NIPSCO has been participating as one of the MISO transmission owners in defending two separate complaints filed at the FERC which challenge the MISO prescribed 12.38% base ROE for electric transmission investments subject to federal jurisdiction rate regulation. On June 30, 2016, the FERC administrative law judge issued an initial decision in the second complaint which authorized the MISO transmission owners to collect a base ROE of 9.7% for the period of February 12, 2015 through May 11, 2016. This initial decision is subject to approval by the full Commission and is not a final order. On September 28, 2016, FERC issued Opinion No. 551, which largely affirmed the initial decision in the first complaint, which set the base ROE for the MISO Transmission Owners at 10.32% for the period of November 12, 2013 through February 11, 2015. The FERC directed the MISO and the MISO Transmission Owners to submit, within 30 days, a compliance filing with revised rates based on the 10.32% base ROE and to provide refunds with interest for the 15-month refund period for this case. The opinion also establishes the going forward base ROE at 10.32% as of September 28, 2016 until the Commission either issues a final order in the second complaint or a new proceeding is initiated to create a new refund period. Incorporating NIPSCO’s 50-basis point adder for independent RTO membership, NIPSCO’s total ROE is set at 10.82% going forward. NIPSCO has an estimated liability of $6.5 million at December 31, 2016 related to this matter.
On November 1, 2016, NIPSCO filed a petition with the IURC for relief regarding the construction of additional environmental projects required to comply with the final rules for regulation of CCRs and the ELG. Refer to Note 18-D, “Environmental Matters,” for more information.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

Commodity Price Risk Management
NiSource and NiSource’s utility customers are exposed to variability in cash flows associated with natural gas purchases and volatility in natural gas prices. NiSource purchases natural gas for sale and delivery to its retail, commercial and industrial customers, and for most customers the variability in the market price of gas is passed through in their rates. Some of NiSource’s utility subsidiaries offer programs where variability in the market price of gas is assumed by the respective utility. The objective of NiSource’s commodity price risk programs is to mitigate the gas cost variability, for NiSource or on behalf of its customers, associated with natural gas purchases or sales by economically hedging the various gas cost components using a combination of futures, options, forwards or other derivative contracts.
In September 2016, NIPSCO received IURC approval to lock in a fixed price for its natural gas customers using long-term forward purchase instruments. The term of these instruments may range from five to ten years and is limited to ten percent of NIPSCO’s average annual GCA purchase volume. Gains and losses on these derivative contracts will be deferred as regulatory liabilities or assets and will be remitted to or collected from customers through NIPSCO’s quarterly GCA mechanism. These instruments are not designated as accounting hedges.
Interest Rate Risk Management
In 2015, NiSource Finance entered into forward-starting interest rate swap agreements with an aggregate notional value of $1.0 billion to hedge the variability in cash flows attributable to changes in the benchmark interest rate during the periods from the effective dates of the swaps to the anticipated dates of forecasted debt issuances which extend into 2018.
In June 2016, NiSource Finance entered into additional forward-starting interest rate swap agreements with an aggregate notional value of $500.0 million to hedge the variability in cash flows attributable to changes in the benchmark interest rate during the periods from the effective dates of the swaps to the anticipated dates of forecasted debt issuances, which are expected to take place by the end of 2018.
As of December 31, 2016, NiSource Finance has forward-starting interest rate swaps with an aggregate notional value totaling $1.5 billion. These interest rate swaps are designated as cash flow hedges. The effective portions of the gains and losses related to these swaps are recorded to AOCI and are recognized in earnings concurrent with the recognition of interest expense on the associated debt, once issued. If it becomes probable that a hedged forecasted transaction will no longer occur, the accumulated gains or losses on the derivative will be recognized currently in earnings. Earnings may also be impacted if the anticipated dates of forecasted debt issuances differ from the dates originally contemplated at hedge inception.
Realized gains and losses from NiSource’s interest rate cash flow hedges are presented in “Interest expense, net” on the Statements of Consolidated Income. There was no material income statement recognition of gains or losses relating to an ineffective portion of NiSource's hedges, nor were there amounts excluded from effectiveness testing for derivatives in cash flow hedging relationships for the years ended December 31, 2016, 2015 and 2014.
NiSource’s derivative instruments measured at fair value as of December 31, 2016 and 2015 do not contain any credit-risk-related contingent features.

The effective income tax rates were 35.7%, 41.6% and 39.4% in 2016, 2015 and 2014, respectively. The 5.9% decrease in the overall effective tax rate in 2016 versus 2015 was primarily the result of a $7.2 million decrease in income taxes related to Federal tax benefits on stock compensation and the absence of $15.0 million of lost Federal tax benefit primarily related to charitable contribution carryforward adjustments recorded in the prior year. Both of these items are discussed in further detail below. The 2.2% increase in the overall effective tax rate in 2015 versus 2014 was primarily a result of a $17.8 million increase in federal income tax associated with write downs of charitable contribution carryforwards, offset by a $10.5 million decrease in income tax expense related to state apportionment changes and permanent items as a result of remeasurement after the Separation.
In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. Among other provisions, the standard requires that all income tax effects of awards are recognized in the income statement when the awards vest and are distributed. NiSource elected to adopt ASU 2016-09 during the third quarter of 2016. Refer to Note 2, “Recent Accounting Pronouncements,” for additional information.

On December 18, 2015, the President signed into law the PATH. PATH, among other provisions, extended and modified bonus depreciation through 2019. In general, 50% bonus depreciation is available for property placed in service before January 1, 2018, 40% bonus depreciation is available for property placed in service before January 1, 2019 and 30% bonus depreciation is available for property placed in service before January 1, 2020. NiSource recorded the effects of PATH in the fourth quarter of 2015.
As a result of PATH and 50% bonus depreciation being extended, NiSource recorded tax expense of $5.8 million in 2015 for the expiration of unused charitable contribution carryforwards which expired due to the 5 year carryover limitation. NiSource also recorded a valuation allowance for an additional $12.0 million of charitable contribution carryforwards that are set to expire in 2016-2019 in the event that NiSource does not have sufficient taxable income to utilize the carryforward amounts.
As a result of a Pennsylvania PUC Order dated December 3, 2015, Columbia of Pennsylvania adjusted the flow through in rates of tax benefits so that the unamortized balance of a change in accounting method for certain capitalized costs of approximately $2.0 million at December 31, 2014 would be amortized through December 2016. The amortization of excess tax benefits was $0.7 million in 2016, $1.4 million in 2015 and $4.1 million in 2014 . On a prospective basis, Columbia of Pennsylvania will recognize deferred tax expense, rather than flow through in rates, the tax benefits resulting from the method change.
On March 25, 2014, the governor of Indiana signed into law Senate Bill I, which among other things, lowers the corporate income tax rate from 6.5% to 4.9% over six years beginning on July 1, 2015. The reduction in the tax rate will impact deferred income taxes and tax-related regulatory assets and liabilities recoverable in the ratemaking process. In addition, deferred tax assets and liabilities, primarily deferred tax assets related to the Indiana net operating loss carry forward, will be reduced to reflect the lower rate at which these temporary differences and tax benefits will be realized. In the first quarter of 2014, NiSource recorded tax expense of $7.1 million to reflect the effect of this rate change. This expense is largely attributable to the remeasurement of the Indiana net operating loss at the 4.9% rate. The majority of NiSource’s tax temporary differences are related to NIPSCO’s utility plant.
Deferred income taxes result from temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. The principal components of NiSource’s net deferred tax liability were as follows:

State income tax net operating loss benefits are recorded at their realizable value. NiSource anticipates it is more likely than not that it will realize $43.6 million and $34.7 million of these tax benefits as of December 31, 2016 and 2015, respectively, prior to their expiration. These tax benefits are primarily related to Indiana and Pennsylvania. The carryforward periods for these tax benefits expire in various tax years from 2028 to 2036. The remaining net operating loss carryforward tax benefit represents a Federal carryforward of $600.9 million that will expire in 2030 and an Alternative Minimum Tax credit of $1.7 million that will carry forward indefinitely.

In 2016, NiSource resolved prior unrecognized tax benefits of $0.9 million and established new unrecognized tax benefits related to State matters of $2.6 million.
The IRS issued Revenue Procedure 2013-24 on April 30, 2013, which provided guidance for repairs related to generation property. Among other things, the Revenue Procedure listed units of property and material components of units of property for purposes of analyzing repair versus capitalization issues. NiSource adopted this Revenue Procedure for income tax filings for 2014. NiSource evaluated and recorded the effect of this change in method enabled by this Revenue Procedure as of December 31, 2013. As a result of the findings received in 2015 for the 2011-2014 audit, NiSource reversed its previously recorded unrecognized tax benefits related to the requested change in tax accounting method in 2015. The reversal of the unrecognized tax benefits did not materially affect tax expense or net income.
In 2015, offsetting the liability for unrecognized tax benefits are $0.9 million of related outstanding tax receivables and net operating loss carryforwards resulting in a net balance of zero, including interest, related to the tax method change issues.
The total amount of unrecognized tax benefits at December 31, 2016, 2015 and 2014 that, if recognized, would affect the effective tax rate is $1.7 million, $0.9 million and $4.1 million, respectively. As of December 31, 2016, it is reasonably possible that a $1.7 million decrease in unrecorded tax benefits could occur in 2017 due primarily to the conclusion of state appeals.
NiSource recognizes accrued interest on unrecognized tax benefits, accrued interest on other income tax liabilities and tax penalties in income tax expense. Interest expense recorded on unrecognized tax benefits and other income tax liabilities was immaterial for all periods presented. There were no accruals for penalties recorded in the Statements of Consolidated Income for the years ended December 31, 2016, 2015 and 2014, and there were no balances for accrued penalties recorded on the Consolidated Balance Sheets as of December 31, 2016 and 2015.
NiSource is subject to income taxation in the United States and various state jurisdictions, primarily Indiana, Pennsylvania, Kentucky, Massachusetts, Maryland, New York and Virginia.
Because NiSource is part of the IRS’s Large and Mid-Size Business program, each year’s federal income tax return is typically audited by the IRS. As of December 31, 2016, tax years through 2015 have been audited and are effectively closed to further assessment. The audit of tax year 2016 under the CAP program is expected to be completed in 2017. NiSource has been accepted into the program for the audit of tax year 2017.
The statute of limitations in each of the state jurisdictions in which NiSource operates remain open until the years are settled for federal income tax purposes, at which time amended state income tax returns reflecting all federal income tax adjustments are filed. As of December 31, 2016, there were no state income tax audits in progress that would have a material impact on the consolidated financial statements.

Pension and Other Postretirement Benefits
NiSource provides defined contribution plans and noncontributory defined benefit retirement plans that cover certain of its employees. Benefits under the defined benefit retirement plans reflect the employees’ compensation, years of service and age at retirement. Additionally, NiSource provides health care and life insurance benefits for certain retired employees. The majority of employees may become eligible for these benefits if they reach retirement age while working for NiSource. The expected cost of such benefits is accrued during the employees’ years of service. Current rates of rate-regulated companies include postretirement benefit costs, including amortization of the regulatory assets that arose prior to inclusion of these costs in rates. For most plans, cash contributions are remitted to grantor trusts.
In connection with the Separation, NiSource entered into an Employees Matters Agreement with CPG, which provides that employees of CPG no longer participate in benefit plans sponsored by NiSource as of the Separation date. Upon the completion of the Separation, the NiSource pension and other postretirement benefit plans transferred assets and obligations to the CPG plans resulting in a net decrease in the pension plans underfunded status of $48.0 million and a net increase in the other postretirement benefit plans underfunded status of $115.9 million. Refer to Note 3, "Discontinued Operations," for additional information.
NiSource Pension and Other Postretirement Benefit Plans’ Asset Management. NiSource employs a liability-driven investing strategy for the pension plan, as noted below. While the majority of assets continue in a total return investment approach, a glide path has been implemented. A mix of equities and fixed income investments are used to maximize the long-term return of plan assets and hedge the liabilities at a prudent level of risk. NiSource utilizes a total return investment approach for the other postretirement benefit plans. Risk tolerance is established through careful consideration of plan liabilities, plan funded status, and asset class volatility. The investment portfolio contains a diversified blend of equity and fixed income investments. Furthermore, equity investments are diversified across U.S. and non-U.S. stocks, as well as growth, value, small and large capitalizations. Other assets such as private equity funds are used judiciously to enhance long-term returns while improving portfolio diversification. Derivatives may be used to gain market exposure in an efficient and timely manner; however, derivatives may not be used to leverage the portfolio beyond the market value of the underlying assets. Investment risk is measured and monitored on an ongoing basis through quarterly investment portfolio reviews, annual liability measurements, and periodic asset/liability studies.
NiSource utilizes a building block approach with proper consideration of diversification and rebalancing in determining the long-term rate of return for plan assets. Historical markets are studied and long-term historical relationships between equities and fixed income are analyzed to ensure that they are consistent with the widely accepted capital market principle that assets with higher volatility generate greater return over the long run. Current market factors, such as inflation and interest rates, are evaluated before long-term capital market assumptions are determined. Peer data and historical returns are reviewed to check for reasonability and appropriateness.
The most important component of an investment strategy is the portfolio asset mix, or the allocation between the various classes of securities available to the pension and other postretirement benefit plans for investment purposes. The asset mix and acceptable minimum and maximum ranges established for the NiSource plan assets represents a long-term view and are listed in the table below.
In 2012, a dynamic asset allocation policy for the pension fund was approved. This policy calls for a gradual reduction in the allocation of return-seeking assets (equities, real estate, private equity and hedge funds) and a corresponding increase in the allocation of liability-hedging assets (fixed income) as the funded status of the plans increase above 90% (as measured by the market value of qualified pension plan assets divided by the projected benefit obligations of the qualified pension plans). In 2016, a study was conducted and approved resulting in the addition of new asset classes in the return-seeking portfolio allocation (i.e. core real estate, diversified credit) and a shift in the hedging allocation (i.e. fixed income). Planned implementation of the new asset classes will begin in 2017.
As of December 31, 2016, the asset mix and acceptable minimum and maximum ranges established by the policy for the pension and other postretirement benefit plans are as follows:

The categorization of investments into the asset classes in the table above are based on definitions established by the NiSource Benefits Committee.
Fair Value Measurements. The following table sets forth, by level within the fair value hierarchy, the Master Trust and other postretirement benefits investment assets at fair value as of December 31, 2016 and 2015. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Total Master Trust and other postretirement benefits investment assets at fair value classified within Level 3 were $73.1 million and $95.3 million as of December 31, 2016 and December 31, 2015, respectively. Such amounts were approximately 4% and 5% of the Master Trust and other postretirement benefits’ total investments as reported on the statement of net assets available for benefits at fair value as of December 31, 2016 and 2015, respectively.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

Valuation Techniques Used to Determine Fair Value:
Level 1 Measurements
Most common and preferred stocks are traded in active markets on national and international securities exchanges and are valued at closing prices on the last business day of each period presented. Cash is stated at cost which approximates fair value, with the exception of cash held in foreign currencies which fluctuates with changes in the exchange rates. Short-term bills and notes are priced based on quoted market values.
Level 2 Measurements
Most U.S. Government Agency obligations, mortgage/asset-backed securities, and corporate fixed income securities are generally valued by benchmarking model-derived prices to quoted market prices and trade data for identical or comparable securities. To the extent that quoted prices are not available, fair value is determined based on a valuation model that includes inputs such as interest rate yield curves and credit spreads. Securities traded in markets that are not considered active are valued based on quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Other fixed income includes futures and options which are priced on bid valuation or settlement pricing.
Commingled funds that hold underlying investments that have prices which are derived from the quoted prices in active markets are classified as Level 2. The funds' underlying assets are principally marketable equity and fixed income securities. Units held in commingled funds are valued at the unit value as reported by the investment managers. The fair value of the investments in commingled funds has been estimated using the net asset value per share of the investments.
Level 3 Measurements
Commingled funds that hold underlying investments that have prices which are not derived from the quoted prices in active markets are classified as Level 3. The respective fair values of these investments are determined by reference to the funds' underlying assets, which are principally marketable equity and fixed income securities. Units held in commingled funds are valued at the unit value as reported by the investment managers. These investments are often valued by investment managers on a periodic basis using pricing models that use market, income and cost valuation methods.
Private equity investment strategies include buy-out, venture capital, growth equity, distressed debt, and mezzanine debt. Private equity investments are held through limited partnerships.
Limited partnerships are valued at estimated fair market value based on their proportionate share of the partnership's fair value as recorded in the partnerships' audited financial statements. Partnership interests represent ownership interests in private equity funds and real estate funds. Real estate partnerships invest in natural resources, commercial real estate and distressed real estate. The fair value of these investments is determined by reference to the funds' underlying assets, which are principally securities, private businesses, and real estate properties. The value of interests held in limited partnerships, other than securities, is determined by the general partner, based upon third-party appraisals of the underlying assets, which include inputs such as cost, operating results, discounted cash flows and market based comparable data. Private equity and real estate limited partnerships typically call capital over a three to five year period and pay out distributions as the underlying investments are liquidated. The typical expected life of these limited partnerships is 10-15 years and these investments typically cannot be redeemed prior to liquidation.
For the year ended December 31, 2016, there were no significant changes to valuation techniques to determine the fair value of NiSource's pension and other postretirement benefits' assets.

(1) The change in benefit obligation for Pension Benefits represents the change in Projected Benefit Obligation while the change in benefit obligation for Other Postretirement Benefits represents the change in Accumulated Postretirement Benefit Obligation.
(2) NiSource recognizes in its Consolidated Balance Sheets the underfunded and overfunded status of its various defined benefit postretirement plans, measured as the difference between the fair value of the plan assets and the benefit obligation.
(3) NiSource determined that for certain rate-regulated subsidiaries the future recovery of pension and other postretirement benefits costs is probable. These rate-regulated subsidiaries recorded regulatory assets and liabilities of $847.5 million and $0.3 million, respectively, as of December 31, 2016, and $928.7 million and $8.1 million, respectively, as of December 31, 2015 that would otherwise have been recorded to accumulated other comprehensive loss.
NiSource’s accumulated benefit obligation for its pension plans was $2,148.9 million and $2,190.5 million as of December 31, 2016 and 2015, respectively. The accumulated benefit obligation as of a date is the actuarial present value of benefits attributed by the pension benefit formula to employee service rendered prior to that date and based on current and past compensation levels. The accumulated benefit obligation differs from the projected benefit obligation disclosed in the table above in that it includes no assumptions about future compensation levels.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

NiSource pension plans were underfunded by $414.9 million at December 31, 2016 compared to being underfunded at December 31, 2015 by $459.6 million. The improvement in the funded status was due primarily to favorable asset returns offset by a decrease in discount rates. NiSource contributed $3.3 million and $2.7 million to its pension plans in 2016 and 2015, respectively.
NiSource’s other postretirement benefit plans were underfunded by $297.6 million at December 31, 2016 compared to being underfunded at December 31, 2015 by $299.9 million. The improvement in funded status was primarily due to favorable asset returns offset by a decrease in discount rates. NiSource contributed approximately $25.5 million and $25.8 million to its other postretirement benefit plans in 2016 and 2015, respectively.
No amounts of NiSource’s pension or other postretirement benefit plans’ assets are expected to be returned to NiSource or any of its subsidiaries in 2016.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

NiSource believes it is appropriate to assume an 8.00% and 7.85% rate of return on pension and other postretirement plan assets, respectively, for its calculation of 2016 pension benefits cost. These rates are primarily based on asset mix and historical rates of return and were adjusted in the current year due to anticipated changes in asset allocation and projected market returns.
Beginning January 1, 2017, NiSource will change the method used to estimate the service and interest components of net periodic benefit cost for pension and other postretirement benefits. This change, compared to the previous method, is expected to result in a decrease in the actuarially-determined service and interest cost components. Historically, NiSource estimated service and interest costs utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. For fiscal 2017 and beyond, NiSource elected to utilize a full yield curve approach to estimate these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. NiSource believes the new approach provides a more precise measurement of service and interest costs by aligning the timing of the plan’s liability cash flows to the corresponding spot rates on the yield curve. The benefit obligations measured under this approach are unchanged. NiSource will account for this change as a change in accounting estimate and accordingly will account for this prospectively.

Based on a December 31 measurement date, the net unrecognized actuarial loss, unrecognized prior service cost (credit), and unrecognized transition obligation that will be amortized into net periodic benefit cost during 2017 for the pension plans are $53.6 million, $(0.7) million and zero, respectively, and for other postretirement benefit plans are $3.0 million, $(4.4) million and zero, respectively.

Common Stock
As of December 31, 2016, NiSource had 400,000,000 authorized shares of common stock with a $0.01 par value.
Common Stock Dividend. Holders of shares of NiSource’s common stock are entitled to receive dividends when, as and if declared by the Board out of funds legally available. The policy of the Board has been to declare cash dividends on a quarterly basis payable on or about the 20th day of February, May, August and November. NiSource has paid quarterly common dividends totaling $0.64, $0.83 and $1.02 per share for the years ended December 31, 2016, 2015 and 2014, respectively. At its January 27, 2017 meeting, the Board declared a quarterly common dividend of $0.175 per share, payable on February 17, 2017 to holders of record on February 10, 2017. NiSource has certain debt covenants which could potentially limit the amount of dividends the Company could pay in order to maintain compliance with these covenants. Refer to Note 14, "Long-Term Debt," for more information. As of December 31, 2016, these covenants did not restrict the amount of dividends that were available to be paid.

Dividend Reinvestment and Stock Purchase Plan. NiSource offers a Dividend Reinvestment and Stock Purchase Plan which allows participants to reinvest dividends and make voluntary cash payments to purchase additional shares of common stock on the open market.

13.
Share-Based Compensation

The NiSource stockholders originally approved and adopted the NiSource Inc. 2010 Omnibus Incentive Plan (“Omnibus Plan”) at the Annual Meeting of Stockholders held on May 11, 2010. Stockholders re-approved the Omnibus Plan as amended at the Annual Meeting of Stockholders held on May 12, 2015. The Omnibus Plan provides for awards to employees and non-employee directors of incentive and nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, cash-based awards and other stock-based awards and supersedes the long-term incentive plan approved by stockholders on April 13, 1994 (“1994 Plan”) and the Director Stock Incentive Plan (“Director Plan”). The Omnibus Plan provides that the number of shares of common stock of NiSource available for awards is 8,000,000 plus the number of shares subject to outstanding awards that expire or terminate for any reason that were granted under either the 1994 Plan or the Director Plan, plus the number of shares that were awarded as a result of the Separation-related adjustments. At December 31, 2016, there were 4,992,782 shares reserved for future awards under the Omnibus Plan.
NiSource recognized stock-based employee compensation expense of $15.1 million, $18.8 million and $29.8 million, during 2016, 2015 and 2014, respectively, as well as related tax benefits of $5.8 million, $7.2 million and $11.8 million, respectively. Additionally, NiSource adopted ASU 2016-09 in the third quarter of 2016 and recognized excess tax benefits from the distribution of vested share-based employee compensation in 2016. For the twelve months ended December 31, 2016, $7.2 million of such benefits were recorded. Refer to Note 2, "Recent Accounting Pronouncements," and Note 10, "Income Taxes," for additional information.
As of December 31, 2016, the total remaining unrecognized compensation cost related to non-vested awards amounted to $16.3 million, which will be amortized over the weighted-average remaining requisite service period of 1.7 years.
Separation-related Adjustments. In connection with the Separation, NiSource and CPG entered into an Employee Matters Agreement, effective July 1, 2015. Under the terms of the Employee Matters Agreement, and pursuant to the terms of the Omnibus Plan, the Compensation Committee of the Board of NiSource approved an adjustment to outstanding awards granted under the Omnibus Plan in order to preserve the intrinsic aggregate value of such awards before the Separation (the “Valuation Adjustment”). The Separation-related adjustments did not have a material impact on either compensation expense or the potentially dilutive securities to be considered in the calculation of diluted earnings per share of common stock. Former NiSource employees transferred to CPG as a result of the Separation surrendered their outstanding unvested NiSource awards effective July 1, 2015.
Restricted Stock Units and Restricted Stock. In 2016, NiSource granted 65,418 restricted stock units and shares of restricted stock, subject to service conditions. The total grant date fair value of the shares of restricted stock units and shares of restricted stock was $1.4 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of any dividends not received during the vesting period, which will be expensed over the vesting period which is generally three years. As of December 31, 2016, all 65,418 non-vested restricted stock units and shares of restricted stock granted in 2016 were outstanding.
In 2015, NiSource granted 660,230 restricted stock units and shares of restricted stock, subject to service conditions. The total grant date fair value of the restricted stock units and shares of restricted stock was $23.9 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of any dividends not received during the vesting period, which will be expensed over the vesting period which is generally three years. Including the effect of the Valuation Adjustment, 750,708 non-vested restricted stock units and shares of restricted stock granted in 2015 were outstanding as of December 31, 2016.

In 2014, NiSource granted 158,633 restricted stock units and shares of restricted stock, subject to service conditions. The total grant date fair value of the restricted stock units and shares of restricted stock was $5.2 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of any dividends not received during the vesting period, which will be expensed over the vesting period which is generally three years. Including the effect of the Valuation Adjustment, 46,810 non-vested restricted stock units and shares of restricted stock granted in 2014 were outstanding as of December 31, 2016.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

As a result of the Separation, restricted stock units were substituted for outstanding performance shares awarded in 2014, as adjusted based on a modified performance period and modified performance goals, and were subject to the same service based vesting conditions as the performance share awards they replaced. These converted restricted stock unit awards were also subject to the Valuation Adjustment. As of December 31, 2016, 736,911 of these restricted stock units remained outstanding.
 
If an employee terminates employment before the service conditions lapse under the 2014, 2015 or 2016 awards due to (1) Retirement or Disability (as defined in the award agreement), or (2) death, the service conditions will lapse on the date of such termination with respect to a pro rata portion of the restricted stock units and shares of restricted stock based upon the percentage of the service period satisfied between the grant date and the date of the termination of employment. In the event of a Change-in-Control (as defined in the award agreement), all unvested shares of restricted stock and restricted stock units awarded prior to 2014 will immediately vest and all unvested shares of restricted stock and restricted stock units awarded in 2014, 2015 and 2016 will immediately vest upon termination of employment occurring in connection with a Change-in-Control. Termination due to any other reason will result in all unvested shares of restricted stock and restricted stock units awarded being forfeited effective on the employee’s date of termination.

Performance Shares. In 2016, NiSource granted 647,305 performance shares subject to service, performance and market conditions. The grant date fair value of the awards was $12.6 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of dividends not received during the vesting period which will be expensed over the three year requisite service period. The performance conditions are based on achievement of certain non-GAAP financial measures: cumulative net operating earnings per share, a non-GAAP financial measure that NiSource defines as income from continuing operations adjusted for certain items, for the three-year period ending December 31, 2018; and relative total shareholder return, a non-GAAP market measure that NiSource defines as the annualized growth in dividends and share price of a share of NiSource's common stock (calculated using a 20 trading day average of NiSource's closing price beginning on December 31, 2015 and ending on December 31, 2018) compared to the total shareholder return performance of a predetermined peer group of companies. A Monte Carlo analysis was used to value the portion of these awards dependent on market conditions. As of December 31, 2016, all 647,305 non-vested performance shares granted were outstanding. The service conditions for these awards lapse on February 28, 2019.
In 2015, NiSource did not grant any performance shares subject to performance and service conditions.
In 2014, NiSource granted 535,037 performance shares subject to performance and service conditions. The grant date fair-value of the awards was $16.6 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of dividends not received during the vesting period which will be expensed over the three year requisite service period. The performance conditions are based on achievement of certain non-GAAP financial measures: cumulative net operating earnings, which NiSource defines as income from continuing operations adjusted for certain items; and cumulative funds from operations, which NiSource defines as net operating cash flows provided by continuing operations, in each case for the three-year period ended December 31, 2016; and relative total shareholder return, a non-GAAP market measure that NiSource defines as the annualized growth in the dividends and share price of a share of NiSource’s common stock (calculated using a 20 trading day average of NiSource’s closing price beginning December 31, 2013 and ending on December 31, 2016) compared to the total shareholder return performance of a predetermined peer group of companies. The service conditions for these awards lapse on February 28, 2017.

Non-employee Director Awards. As of May 11, 2010, awards to non-employee directors may be made only under the Omnibus Plan. Currently, restricted stock units are granted annually to non-employee directors, subject to a non-employee director’s election to defer receipt of such restricted stock unit award. The non-employee director’s restricted stock units vest on the last day of the non-employee director’s annual term corresponding to the year the restricted stock units were awarded subject to special pro-rata vesting rules in the event of Retirement or Disability (as defined in the award agreement), or death. The vested restricted stock units are payable as soon as practicable following vesting except as otherwise provided pursuant to the non-employee director’s election to defer. Certain restricted stock units remain outstanding from the Director Plan. All such awards are fully vested and shall be distributed to the directors upon their separation from the Board.
As of December 31, 2016, 218,581 restricted stock units are outstanding to non-employee directors under either the Omnibus Plan or the Director Plan. Of this amount, 40,932 restricted stock units are nonvested and expected to vest.
401(k) Match, Profit Sharing and Company Contribution. NiSource has a voluntary 401(k) savings plan covering eligible employees that allows for periodic discretionary matches as a percentage of each participant’s contributions payable in shares of NiSource common stock. NiSource also has a retirement savings plan that provides for discretionary profit sharing contributions payable in shares of NiSource common stock to eligible employees based on earnings results; and eligible employees hired after January 1, 2010 receive a non-elective company contribution of 3% of eligible pay payable in shares of NiSource common stock. For the years ended December 31, 2016, 2015 and 2014, NiSource recognized 401(k) match, profit sharing and non-elective contribution expense of $32.3 million, $27.4 million and $28.1 million, respectively.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

During 2016, NiSource Finance redeemed $291.5 million of fixed-rate long-term debt at maturity, entered into a $500 million term loan agreement and entered into forward starting swap-lock transactions with notional values totaling $500.0 million, while NIPSCO redeemed a total of $130.0 million of pollution control bonds. These transactions are detailed as follows:
On March 15, 2016, NiSource Finance redeemed $201.5 million of 10.75% senior unsecured notes at maturity.
On March 31, 2016, NiSource Finance entered into a $500 million term loan agreement with a syndicate of banks. The term loan matures March 29, 2019, at which point any and all outstanding borrowings under the agreement are due. Interest charged on borrowings depends on the variable rate structure elected by NiSource Finance at the time of each borrowing. The available variable rate structures from which NiSource Finance may choose are defined in the term loan agreement. As of December 31, 2016, NiSource Finance had $500.0 million of outstanding borrowings under the term loan agreement.
In June 2016, NiSource Finance entered into forward-starting interest rate swaps with an aggregate notional amount of $500.0 million to hedge the variability in cash flows attributable to changes in the benchmark interest rate during the period from the effective date of the swaps to the anticipated date of forecasted debt issuances, expected to take place by the end of 2018. The forward-starting interest rate swaps were designated as cash flow hedges at the time the agreements were executed, whereby any gain or loss recognized from the effective date of the swaps to the date the associated debt is issued for the effective portion of the hedge is recorded net of tax in AOCI and amortized as a component of interest expense over the life of the designated debt. If some portion of the hedges becomes ineffective, the associated gain or loss will be recognized in earnings. As of December 31, 2016, no ineffectiveness has been recorded.
On November 1, 2016, NIPSCO redeemed $130.0 million of 5.60% pollution control bonds at maturity.
On November 28, 2016, NiSource Finance redeemed $90.0 million of 5.41% senior unsecured notes at maturity.
During 2015, NiSource Finance executed a $750.0 million tender offer on fixed-rate long-term debt, redeemed $230.0 million fixed-rate long-term debt at maturity, settled $1,075.0 million term loans, and entered into two forward starting swap-lock transactions with notional values totaling $1,000.0 million. These transactions are detailed as follows:
Prior to the Separation, CPG closed its placement of $2,750.0 million in aggregate principal amount of its senior notes. Using the proceeds from this offering, CPG made cash payments to NiSource representing the settlement of inter-company borrowings and the payment of a one-time special dividend. In May 2015, using proceeds from the cash payments from CPG, NiSource Finance settled its two bank term loans in the amount of $1,075.0 million and executed a tender offer for $750.0 million consisting of a combination of its 5.25% notes due 2017, 6.40% notes due 2018 and 4.45% notes due 2021. In conjunction with the debt retired, NiSource Finance recorded a $97.2 million loss on early extinguishment of long-term debt, primarily attributable to early redemption premiums.
On November 28, 2015, NiSource Finance redeemed $230.0 million of 5.36% senior unsecured notes at maturity.
In December 2015, NiSource Finance entered into forward starting interest rate swaps, with an aggregate notional amount of $1.0 billion, to hedge the variability in cash flows attributable to changes in the benchmark interest rate during the period from the effective date of the swap to the anticipated date of forecasted debt issuances by the end of 2018. The forward starting interest rate swaps were designated as cash flow hedges at the time the agreements were executed.
See Note 18-A, "Contractual Obligations," for the outstanding long-term debt maturities at December 31, 2016.
Unamortized debt expense, premium and discount on long-term debt applicable to outstanding bonds are being amortized over the life of such bonds.
NiSource is subject to a financial covenant under its revolving credit facility which requires NiSource to maintain a debt to capitalization ratio that does not exceed 70%. A similar covenant in a 2005 private placement note purchase agreement requires NiSource to maintain a debt to capitalization ratio that does not exceed 75%. As of December 31, 2016, the ratio was 66%.
NiSource is also subject to certain other non-financial covenants under the revolving credit facility. Such covenants include a limitation on the creation or existence of new liens on NiSource’s assets, generally exempting liens on utility assets, purchase money security interests, preexisting security interests and an additional subset of assets equal to $150 million. An asset sale covenant generally restricts the sale, conveyance, lease, transfer or other disposition of NiSource’s assets to those dispositions that are for a price not materially less than fair market of such assets, that would not materially impair the ability of NiSource and

52

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

NiSource Finance to perform obligations under the revolving credit facility, and that together with all other such dispositions, would not have a material adverse effect. The covenant also restricts dispositions to no more than 10% of NiSource's consolidated total assets on December 31, 2015. The revolving credit facility also includes a cross-default provision, which triggers an event of default under the credit facility in the event of an uncured payment default relating to any indebtedness of NiSource or any of its subsidiaries in a principal amount of $50.0 million or more.
NiSource’s indentures generally do not contain any financial maintenance covenants. However, NiSource’s indentures are generally subject to cross-default provisions ranging from uncured payment defaults of $5 million to $50 million, and limitations on the incurrence of liens on NiSource’s assets, generally exempting liens on utility assets, purchase money security interests, preexisting security interests and an additional subset of assets capped at 10% of NiSource’s consolidated net tangible assets.
 
 
15.
Short-Term Borrowings
NiSource generates short-term borrowings from its revolving credit facility, commercial paper program, letter of credit issuances and accounts receivable transfer programs. Each of these borrowing sources is described further below.
NiSource Finance maintains a revolving credit facility to fund ongoing working capital requirements including the provision of liquidity support for its $1.5 billion commercial paper program, provide for issuance of letters of credit and also for general corporate purposes. On November 28, 2016, NiSource Finance amended its existing revolving credit facility with a syndicate of banks led by Barclays Bank to increase the aggregate commitments from $1.5 billion to $1.85 billion and extend the termination date to November 28, 2021. At December 31, 2016 and 2015, NiSource had no outstanding borrowings under this facility.
NiSource Finance's commercial paper program has a program limit of up to $1.5 billion with a dealer group comprised of Barclays, Citigroup, Credit Suisse and Wells Fargo. At December 31, 2016, NiSource had $1,178.0 million of commercial paper outstanding. At December 31, 2015, NiSource had $321.4 million of commercial paper outstanding.
As of December 31, 2016 and 2015, NiSource had $14.7 million of stand-by letters of credit outstanding all of which were under the revolving credit facility.
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term debt on the Consolidated Balance Sheets in the amount of $310.0 million and $246.0 million as of December 31, 2016 and 2015, respectively. Refer to Note 17, "Transfers of Financial Assets," for additional information.
Short-term borrowings were as follows:

Risk management assets and liabilities include interest rate swaps, exchange-traded NYMEX futures and NYMEX options and non-exchange-based forward purchase contracts. Exchange-traded derivative contracts are based on unadjusted quoted prices in active markets and are classified within Level 1. These financial assets and liabilities are secured with cash on deposit with the exchange; therefore, nonperformance risk has not been incorporated into these valuations. Certain non-exchange-traded derivatives are valued using broker or over-the-counter, on-line exchanges. In such cases, these non-exchange-traded derivatives are classified within Level 2. Non-exchange-based derivative instruments include swaps, forwards and options. In certain instances, these instruments may utilize models to measure fair value. NiSource uses a similar model to value similar instruments. Valuation models utilize various inputs that include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, other observable inputs for the asset or liability and market-corroborated inputs, (i.e., inputs derived principally from or corroborated by observable market data by correlation or other means). Where observable inputs are available for substantially the full term of the asset or liability, the instrument is categorized within Level 2. Certain derivatives trade in less active markets with a lower availability of pricing information and models may be utilized in the valuation. When such inputs have a significant impact on the measurement of fair value, the instrument is categorized within Level 3. Credit risk is considered in the fair value calculation of derivative instruments that are not exchange-traded. Credit exposures are adjusted to reflect collateral agreements which reduce exposures. As of December 31, 2016 and 2015, there were

54

NISOURCE INC.
Notes to Consolidated Financial Statements

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

no material transfers between fair value hierarchies. Additionally there were no changes in the method or significant assumptions used to estimate the fair value of NiSource’s financial instruments.
NiSource Finance has entered into forward-starting interest rate swaps to hedge the interest rate risk on coupon payments of forecasted issuances of long-term debt. These swaps are designated as cash flow hedges. Credit risk is considered in the fair value calculation of each interest rate swap. As they are based on observable data and valuations of similar instruments, the interest rate swaps are categorized within Level 2 of the fair value hierarchy. There was no exchange of premium at the initial date of the swaps, and NiSource can settle the swaps at any time. For additional information see Note 9, "Risk Management Activities."
Available-for-sale securities are investments pledged as collateral for trust accounts related to NiSource’s wholly-owned insurance company. Available-for-sale securities are included within “Other investments” in the Consolidated Balance Sheets. NiSource values U.S. Treasury, corporate and mortgage-backed securities using a matrix pricing model that incorporates market-based information. These securities trade less frequently and are classified within Level 2. Total unrealized gains and losses from available-for-sale securities are included in other comprehensive income (loss).

For the years ended December 31, 2016, 2015, and 2014, the realized gain on sale of available for sale U.S. Treasury debt securities was zero, $0.2 million and $0.1 million, respectively. For the years ended December 31, 2016, 2015, and 2014, the realized gain on sale of available for sale Corporate/Other debt securities was $0.2 million, $0.2 million, and $0.4 million, respectively.
The cost of maturities sold is based upon specific identification. At December 31, 2016, approximately $0.5 million of U.S. Treasury securities have maturities of less than a year while the remaining securities have maturities of greater than one year. At December 31, 2016, approximately $15.2 million of Corporate/Other debt securities have maturities of less than a year while the remaining securities have maturities of greater than one year.
There are no material items in the fair value reconciliation of Level 3 assets and liabilities measured at fair value on a recurring basis for the years ended December 31, 2016 and 2015.
Non-recurring Fair Value Measurements. There were no significant non-recurring fair value measurements recorded during the twelve months ended December 31, 2016.
B.         Other Fair Value Disclosures for Financial Instruments. The carrying amount of cash and cash equivalents, restricted cash, notes receivable, customer deposits and short-term borrowings is a reasonable estimate of fair value due to their liquid or short-term nature. NiSource’s long-term borrowings are recorded at historical amounts.
The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate fair value.
Long-term debt.The fair values of these securities are estimated based on the quoted market prices for the same or similar securities. Certain premium costs associated with the early settlement of long-term debt are not taken into consideration in determining fair

Transfers of Financial Assets
Columbia of Ohio is under an agreement to sell, without recourse, substantially all of its trade receivables, as they originate, to CGORC, a wholly-owned subsidiary of Columbia of Ohio. CGORC, in turn, is party to an agreement with BTMU and BNS, under the terms of which it sells an undivided percentage ownership interest in its accounts receivable to BTMU and a commercial paper conduit sponsored by BNS. This agreement was last renewed on October 14, 2016; the current agreement expires on October 13, 2017, and can be further renewed if mutually agreed to by all parties. The maximum seasonal program limit under the terms of the current agreement is $240 million. As of December 31, 2016, $100.0 million of accounts receivable had been transferred by CGORC. CGORC is a separate corporate entity from NiSource and Columbia of Ohio, with separate obligations, and upon a liquidation of CGORC, CGORC’s obligations must be satisfied out of CGORC’s assets prior to any value becoming available to CGORC’s stockholder.
NIPSCO is under an agreement to sell, without recourse, substantially all of its trade receivables, as they originate, to NARC, a wholly-owned subsidiary of NIPSCO. NARC, in turn, is party to an agreement with PNC and Mizuho under the terms of which it sells an undivided percentage ownership interest in its accounts receivable to PNC and Mizuho. This agreement was last renewed on August 24, 2016; the current agreement expires on August 23, 2017, and can be further renewed if mutually agreed to by all parties. The maximum seasonal program limit under the terms of the current agreement is $200 million. As of December 31, 2016, $175.0 million of accounts receivable had been transferred by NARC. NARC is a separate corporate entity from NiSource and NIPSCO, with separate obligations, and upon a liquidation of NARC, NARC’s obligations must be satisfied out of NARC’s assets prior to any value becoming available to NARC’s stockholder.
Columbia of Pennsylvania is under an agreement to sell, without recourse, substantially all of its trade receivables, as they originate, to CPRC, a wholly-owned subsidiary of Columbia of Pennsylvania. CPRC, in turn, is party to an agreement with BTMU under the terms of which it sells an undivided percentage ownership interest in its accounts receivable to a commercial paper conduit sponsored by BTMU. The agreement with BTMU was last renewed on March 9, 2016; the current agreement expires on March 8, 2017, and can be further renewed if mutually agreed to by both parties. The maximum seasonal program limit under the terms of the agreement is $75 million. As of December 31, 2016, $35.0 million of accounts receivable had been transferred by CPRC. CPRC is a separate corporate entity from NiSource and Columbia of Pennsylvania, with separate obligations, and upon a liquidation of CPRC, CPRC’s obligations must be satisfied out of CPRC’s assets prior to any value becoming available to CPRC’s stockholder.
All accounts receivables sold to the purchasers are valued at face value, which approximates fair value due to their short-term nature. The amount of the undivided percentage ownership interest in the accounts receivables sold is determined in part by required loss reserves under the agreements.
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term borrowings on the Consolidated Balance Sheets. As of December 31, 2016, the maximum amount of debt that can be recognized related to NiSource’s accounts receivable programs is $310.0 million.

(1) Long-term debt balance excludes unamortized issuance costs and discounts of $41.6 million.
(2) Capital lease payments shown above are inclusive of interest totaling $92.6 million.
(3) Operating lease balances do not include amounts for fleet leases that can be renewed beyond the initial lease term. The Company anticipates renewing the leases beyond the initial term, but the anticipated payments associated with the renewals do not meet the definition of expected minimum lease payments and therefore are not included above. Expected payments are $31.1 million in 2017, $32.9 million in 2018, $26.1 million in 2019, $17.5 million in 2020, $8.0 million in 2021 and $2.0 million thereafter.  
(4)In January 2017, NIPSCO signed new coal contract commitments of $24.2 million and $10.1 million for 2017 and 2018, respectively. These contracts are not included above.  

Operating and Capital Lease Commitments. NiSource leases assets in several areas of its operations. Payments made in connection with operating leases were $52.0 million in 2016, $47.5 million in 2015 and $59.8 million in 2014, and are primarily charged to operation and maintenance expense as incurred. Capital lease assets and related accumulated depreciation included in the Consolidated Balance Sheets were $167.0 million and $20.6 million at December 31, 2016, and $236.2 million and $44.0 million at December 31, 2015, respectively.
Included in capital leases are the adjusted payments for the NIPSCO service agreement with Pure Air. Refer to section E, "Other Matters," below for additional information.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

Purchase and Service Obligations. NiSource has entered into various purchase and service agreements whereby NiSource is contractually obligated to make certain minimum payments in future periods. NiSource’s purchase obligations are for the purchase of physical quantities of natural gas, electricity and coal. NiSource’s service agreements encompass a broad range of business support and maintenance functions which are generally described below.
NiSource’s subsidiaries have entered into various energy commodity contracts to purchase physical quantities of natural gas, electricity and coal. These amounts represent minimum quantities of these commodities NiSource is obligated to purchase at both fixed and variable prices.
In July 2008, the IURC issued an order approving NIPSCO’s purchase power agreements with subsidiaries of Iberdrola Renewables, Buffalo Ridge I LLC and Barton Windpower LLC. These agreements provide NIPSCO the opportunity and obligation to purchase up to 100 mw of wind power generated commencing in early 2009. The contracts extend 15 and 20 years, representing 50 mw of wind power each. No minimum quantities are specified within these agreements due to the variability of electricity generation from wind, so no amounts related to these contracts are included in the table above. Upon any termination of the agreements by NIPSCO for any reason (other than material breach by Buffalo Ridge I LLC or Barton Windpower LLC), NIPSCO may be required to pay a termination charge that could be material depending on the events giving rise to termination and the timing of the termination. NIPSCO began purchasing wind power in April 2009.
NiSource has pipeline service agreements that provide for pipeline capacity, transportation and storage services. These agreements, which have expiration dates ranging from 2017 to 2045, require NiSource to pay fixed monthly charges.
NIPSCO has contracts with three major rail operators providing for coal transportation services for which there are certain minimum payments. These service contracts extend for various periods through 2018.
On December 31, 2013, NiSource Corporate Services signed a seven-year agreement with IBM to continue to provide business process and support functions to NiSource under a combination of fixed or variable charges, with the variable charges fluctuating based on the actual need for such services. The agreement was effective January 1, 2014 with a commencement date of April 1, 2014 and includes some targeted service enhancements as well as continued existing information technology support services and a few additional support services.
NiSource has initiated a process to evaluate its future IT business process and support model, which included the issuance of a request for proposal from several service providers, including IBM. Upon any termination of the agreement by NiSource for any reason (other than material breach by IBM), NiSource may be required to pay IBM a termination charge that could include a breakage fee, repayment of IBM's capital investments not yet recovered and IBM's wind-down expense. This termination fee could be material depending on the events giving rise to the termination and the timing of the termination.
B.        Guarantees and Indemnities. As a part of normal business, NiSource and certain subsidiaries enter into various agreements providing financial or performance assurance to third parties on behalf of certain subsidiaries. Such agreements include guarantees and stand-by letters of credit. These agreements are entered into primarily to support or enhance the creditworthiness otherwise attributed to a subsidiary on a stand-alone basis, thereby facilitating the extension of sufficient credit to accomplish the subsidiaries’ intended commercial purposes. At December 31, 2016, NiSource had issued stand-by letters of credit of $14.7 million for the benefit of third parties.
C.         Legal Proceedings. The Company is party to certain claims and legal proceedings arising in the ordinary course of business, none of which is deemed to be individually material at this time. Due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on the Company’s results of operations, financial position or liquidity. If one or more of such matters were decided against the Company, the effects could be material to the Company’s results of operations in the period in which the Company would be required to record or adjust the related liability and could also be material to the Company’s cash flows in the periods the Company would be required to pay such liability.
D.        Environmental Matters. NiSource operations are subject to environmental statutes and regulations related to air quality, water quality, hazardous waste and solid waste. NiSource believes that it is in substantial compliance with the environmental regulations currently applicable to its operations.
It is management's continued intent to address environmental issues in cooperation with regulatory authorities in such a manner as to achieve mutually acceptable compliance plans. However, there can be no assurance that fines and penalties will not be

incurred. Management expects a significant portion of environmental assessment and remediation costs to be recoverable through rates for certain NiSource companies.
As of December 31, 2016 and 2015, NiSource had recorded a liability of approximately $111.4 million and $123.2 million, respectively, to cover environmental remediation at various sites. The current portion of this liability is included in "Legal and environmental" in the Consolidated Balance Sheets. The noncurrent portion is included in "Other noncurrent liabilities" in the Consolidated Balance Sheets. NiSource recognizes costs associated with environmental remediation obligations when the incurrence of such costs is probable and the amounts can be reasonably estimated. The original estimates for remediation activities may differ materially from the amount ultimately expended. The actual future expenditures depend on many factors, including currently enacted laws and regulations, the nature and extent of impact, the method of remediation and the availability of cost recovery. These expenditures are not currently estimable at some sites. NiSource periodically adjusts its liability as information is collected and estimates become more refined.
Electric Operations' compliance estimates disclosed below are reflective of NIPSCO's Integrated Resource Plan submitted to the IURC on November 1, 2016. See section E, "Other Matters" below for additional information.
Air
The actions listed below could require further reductions in emissions from various emission sources. NiSource will continue to closely monitor developments in these matters.
Climate Change. Future legislative and regulatory programs, including implementation of the EPA CPP, could significantly limit allowed GHG emissions or impose a cost or tax on GHG emissions. Additionally, rules that increase methane leak detection, require emission reductions or impose additional requirements for natural gas facilities could restrict GHG emissions and impose additional costs. The CPP and other federally enacted or proposed GHG reduction measures are subject to numerous legal challenges that could change the way the programs are implemented, and NiSource will carefully monitor all GHG reduction proposals and regulations.
National Ambient Air Quality Standards. The CAA requires the EPA to set NAAQS for six "criteria" air pollutants considered harmful to public health and the environment. Periodically, the EPA imposes new, or modifies existing, NAAQS. States containing areas that do not meet the new or revised standards, or contribute significantly to nonattainment of downwind states, may be required to take steps to achieve and maintain compliance with the standards. These steps could include additional pollution controls on boilers, engines, turbines and other facilities owned by electric generation and gas distribution operations.
The following NAAQS were recently added or modified:
Ozone. On October 26, 2015, the EPA issued a final rule to lower the 8-hour ozone standard from 75 ppb to 70 ppb. After the EPA proceeds with designations, areas where NiSource operates that are currently designated in attainment with the standards may be reclassified as nonattainment. NiSource will continue to monitor this matter and cannot estimate its impact at this time.
Clean Power Plan. On October 23, 2015, the EPA issued a final rule to regulate CO2 emissions from existing fossil-fuel EGUs under section 111(d) of the CAA. The final rule establishes national CO2 emission-rate standards that are applied to each state’s mix of affected EGUs to establish state-specific emission-rate and mass-emission limits. The final rule requires each state to submit a plan indicating how the state will meet the EPA's emission-rate or mass-emission limit, including possibly imposing reduction obligations on specific units. If a state does not submit a satisfactory plan, the EPA will impose a federal plan on that state. On February 9, 2016, the U.S. Supreme Court stayed implementation of the CPP until litigation is decided on its merits. The cost to comply with this rule will depend on a number of factors, including the outcome of CPP litigation, the requirements of the state plan or final federal plan, and the level of NIPSCO's required CO2 emission reductions. It is possible that this new rule, comprehensive federal or state GHG legislation or other GHG regulation could result in additional expense or compliance costs that could materially impact NiSource's financial results. NIPSCO will continue to monitor this matter and cannot estimate its impact at this time. Should costs be incurred to comply with the CPP, NIPSCO believes such costs will be eligible for recovery through customer rates.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

Waste
CERCLA. NiSource subsidiaries are potentially responsible parties at waste disposal sites under the CERCLA (commonly known as Superfund) and similar state laws. Additionally, NiSource affiliates have retained environmental liabilities, including remediation liabilities, associated with certain former operations.
MGP. A program has been instituted to identify and investigate former MGP sites where Gas Distribution Operations subsidiaries or predecessors may have liability. The program has identified 64 such sites where liability is probable. Remedial actions at many of these sites are being overseen by state or federal environmental agencies through consent agreements or voluntary remediation agreements.
NiSource utilizes a probabilistic model to estimate its future remediation costs related to its MGP sites. The model was prepared with the assistance of a third-party and incorporates NiSource and general industry experience with remediating MGP sites. NiSource completes an annual refresh of the model in the second quarter of each fiscal year. No material changes to the estimated future remediation costs were noted as a result of the refresh completed as of June 30, 2016. The total estimated liability at NiSource related to the facilities subject to remediation was $105.5 million and $110.4 million at December 31, 2016 and 2015, respectively. The liability represents NiSource’s best estimate of the probable cost to remediate the facilities. NiSource believes that it is reasonably possible that remediation costs could vary by as much as $25 million in addition to the costs noted above. Remediation costs are estimated based on the best available information, applicable remediation standards at the balance sheet date, and experience with similar facilities.
CCRs. On April 17, 2015, the EPA issued a final rule for regulation of CCRs. The rule regulates CCRs under the RCRA Subtitle D, which determines them to be nonhazardous. The rule is implemented in phases and requires increased groundwater monitoring, reporting, record keeping and posting of related information to the Internet. The rule also establishes requirements related to CCR management and disposal. The rule will allow NIPSCO to continue its byproduct beneficial use program.
The publication of the CCR rule resulted in revisions to previously recorded legal obligations associated with the retirement of certain NIPSCO facilities. The actual asset retirement costs related to the CCR rule may vary substantially from the estimates used to record the increased asset retirement obligation due to the uncertainty about the compliance strategies that will be used and the preliminary nature of available data used to estimate costs. Refer to Note 7, "Asset Retirement Obligations," for further information. In addition, to comply with the rule, NIPSCO will be required to incur future capital expenditures to modify its infrastructure and manage CCRs. Based upon a preliminary engineering study, capital compliance costs are currently expected to cost approximately $230 million. As allowed by the EPA, NIPSCO will continue to collect data over time to determine the specific compliance solutions and associated costs and, as a result, the actual costs may vary. NIPSCO has filed a petition with the IURC seeking approval of the projects and to recover the costs associated with CCR compliance.
Water
ELG. On November 3, 2015, the EPA issued a final rule to amend the ELG and standards for the Steam Electric Power Generating category. The final rule became effective January 4, 2016. The rule imposes new water treatment and discharge requirements on NIPSCO's electric generating facilities to be applied between 2018 and 2023. Based upon a preliminary engineering study, capital compliance costs are currently expected to cost approximately $170 million. NIPSCO has filed a petition with the IURC seeking approval of the projects and to recover the costs associated with ELG compliance.
E.     Other Matters.
Transmission Upgrade Agreements. On February 11, 2014, NIPSCO entered into TUAs with upgrade sponsors to complete upgrades on NIPSCO’s transmission system on behalf of those sponsors. The upgrade sponsors agreed to reimburse NIPSCO for the total cost to construct transmission upgrades and place them into service, multiplied by a rate of 1.71 ("the multiplier").
On June 10, 2014, certain upgrade sponsors for both TUAs filed a complaint at the FERC against NIPSCO regarding the multiplier stated in the TUAs. On June 30, 2014, NIPSCO filed an answer defending the terms of the TUAs and the just and reasonable nature of the multiplier charged therein and moved for dismissal of the complaint. On December 8, 2014, the FERC issued an order in response to the complaint finding that it is appropriate for NIPSCO to recover, through the multiplier, substantiated costs of ownership related to the TUAs. On August 10, 2016, NIPSCO reached settlement with all remaining parties to the complaint and filed with the FERC for approval. An order from the FERC approving the settlement was received on January 31, 2017. Receipt of the FERC order did not result in a material impact to the Consolidated Financial Statements.
At the time the TUAs were executed, it was assumed the proceeds received from the upgrade sponsors would be taxable to NIPSCO. Accordingly, the multiplier included a provision for such taxes. On June 10, 2016, the U.S. Treasury Department issued a notice

60

NISOURCE INC.
Notes to Consolidated Financial Statements

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA (continued)

regarding transfers of property to regulated utilities by electric generators, stating that transfers within the scope of the notice will not be treated as taxable. In response to this notice, NIPSCO recorded a liability of $8.6 million to reflect the estimated amount owed to the upgrade sponsors for the portion of the multiplier previously collected for taxes. This activity is recorded within "Other, net" in the Statements of Consolidated Income (Loss).
PHMSA Transmission. On March 17, 2016, PHMSA issued a proposed rule that would, if adopted, add new assessment and data requirements to existing transmission facilities that would necessitate expanded investigation and repair/replace activity on these facilities over the next 15 years. The comment period for the proposed rule closed on July 7, 2016. If adopted as proposed, this rule may require NiSource to incur significant incremental capital and operation and maintenance expenditures to achieve compliance. NiSource will continue to monitor this matter, and cannot reasonably estimate its impact at this time.
PHMSA EFV. On October 14, 2016, PHMSA issued a final rule that expands safety requirements for EFVs. Among the rule's provisions is a requirement for utilities to notify customers whose service lines are not currently equipped with an EFV of their right to request installation of an EFV. The rule takes effect April 14, 2017. NiSource is evaluating potential impacts of this regulation on its operations and cannot reasonably estimate its impact at this time.
NIPSCO 2016 Integrated Resource Plan. Environmental, regulatory and economic factors, including low natural gas prices and aging coal-fired units, have led NIPSCO to consider modifying its current electric generation supply mix to include less coal-fired generation. Due to enacted CCR and ELG legislation, NIPSCO would expect to incur over $1 billion in operating, maintenance, environmental and other costs over the next seven years if the current fleet of coal-fired generating units remain operational.
On November 1, 2016, NIPSCO submitted its 2016 Integrated Resource Plan with the IURC. The plan evaluates demand-side and supply-side resource alternatives to reliably and cost effectively meet NIPSCO customers' future energy requirements over the next twenty years. The 2016 Integrated Resource Plan indicates that the most viable option for customers and NIPSCO involves the retirement of Bailly Generating Station (Units 7 and 8) as soon as mid-2018 and two units (Units 17 and 18) at the R.M. Schahfer Generating Station by the end of 2023. It is projected over the long term that the cost to customers to retire these units at these dates will be lower than maintaining and upgrading them for continuing generation.
NiSource and NIPSCO committed to the retirement of the Bailly Generating Station units in connection with the filing of the 2016 Integrated Resource Plan. However, retirement of these units is subject to the approval of the MISO, which is responsible for coordinating, controlling and monitoring the use of the electric transmission system by utilities, generators and marketers across parts of 15 U.S. states and the Canadian province of Manitoba. In the fourth quarter of 2016, the MISO approved NIPSCO's plan to retire the Bailly Generating Station units by May 31, 2018. In accordance with ASC 980-360, the remaining net book value of the Bailly Generating Station units was reclassified from "Net utility plant" to "Other property, at cost, less accumulated depreciation" on the Consolidated Balance Sheets. Refer to Note 5, "Property, Plant and Equipment" for further information.
In connection with the MISO's approval of NIPSCO's planned retirement of the Bailly Generating Station units, NiSource recorded $22.1 million of plant retirement-related charges in the fourth quarter of 2016. These charges were comprised of contract termination charges related to NIPSCO's capital lease with Pure Air (discussed further below), voluntary employee severance benefits, and write downs of certain materials and supplies inventory balances. These charges are presented within "Operation and maintenance" on the Statements of Consolidated Income.
NIPSCO Pure Air. NIPSCO has a service agreement with Pure Air, a general partnership between Air Products and Chemicals, Inc. and First Air Partners LP, under which Pure Air provides scrubber services to reduce sulfur dioxide emissions for Units 7 and 8 at the Bailly Generating Station. Services under this contract commenced on July 1, 1992 and expired on June 30, 2012. The agreement was renewed effective July 1, 2012 for ten years requiring NIPSCO to pay for the services under a combination of fixed and variable charges. NiSource has made an exhaustive effort to obtain information needed from Pure Air to determine the status of Pure Air as a VIE. However, NIPSCO has not been able to obtain this information and, as a result, it is unclear whether Pure Air is a VIE and if NIPSCO is the primary beneficiary. NIPSCO will continue to request the information required to determine whether Pure Air is a VIE. NIPSCO has no exposure to loss related to the service agreement with Pure Air and payments under this agreement were $21.7 million and $19.5 million for the years ended December 31, 2016 and 2015, respectively. In accordance with GAAP, the renewed agreement was evaluated to determine whether the arrangement qualifies as a lease. Based on the terms of the agreement, the arrangement qualified for capital lease accounting. As the effective date of the new agreement was July 1, 2012, NiSource capitalized this lease beginning in the third quarter of 2012.
As further discussed above in this Note 18 under the heading "NIPSCO 2016 Integrated Resource Plan," NIPSCO plans to retire the generation station units serviced by Pure Air by May 31, 2018. In December 2016, as allowed by the provisions of the service

agreement, NIPSCO provided Pure Air formal notice of intent to terminate the service agreement, effective May 31, 2018. Providing this notice to Pure Air triggered a contract termination liability of $16 million which was recorded in fourth quarter of 2016. This expense was included as part of the plant retirement-related charges discussed above. Payment of this liability is not due until NIPSCO ceases use of the scrubber services. The liability is presented in "Other noncurrent liabilities" on the Consolidated Balance Sheets. In addition, NIPSCO remeasured the remaining capital lease asset and obligation to reflect the change in estimated remaining minimum lease payments. This remeasurement was a non-cash transaction that had no impact on the Statements of Consolidated Income.

Segments of Business
At December 31, 2016, NiSource’s operations are divided into two primary reportable segments. The Gas Distribution Operations segment provides natural gas service and transportation for residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, Maryland, Indiana and Massachusetts. The Electric Operations segment provides electric service in 20 counties in the northern part of Indiana.
The following table provides information about business segments. NiSource uses operating income as its primary measurement for each of the reported segments and makes decisions on finance, dividends and taxes at the corporate level on a consolidated basis. Segment revenues include intersegment sales to affiliated subsidiaries, which are eliminated in consolidation. Affiliated sales are recognized on the basis of prevailing market, regulated prices or at levels provided for under contractual agreements. Operating income is derived from revenues and expenses directly associated with each segment.
