Notes to Condensed Consolidated Financial Statements (unaudited)

 
1.    Basis of Accounting Presentation

The accompanying Condensed Consolidated Financial Statements (unaudited) for NiSource (the “Company”) reflect all normal recurring adjustments that are necessary, in the opinion of management, to present fairly the results of operations in accordance with GAAP in the United States of America. The accompanying financial statements contain the accounts of the Company and its majority-owned or controlled subsidiaries, including CPPL (see Note 3).
The accompanying financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in NiSource’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Income for interim periods may not be indicative of results for the calendar year due to weather variations and other factors.

The Condensed Consolidated Financial Statements (unaudited) have been prepared pursuant to the rules and regulations of the SEC. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although NiSource believes that the disclosures made are adequate to make the information not misleading. 

Planned Separation of Columbia Pipeline Group
On September 28, 2014, NiSource announced that its Board of Directors had approved in principle plans to separate its natural gas pipeline and related businesses into a stand-alone publicly traded company (the “Proposed Separation”). If completed, the Proposed Separation will result in two energy infrastructure companies: NiSource Inc., a fully regulated natural gas and electric utilities company, and Columbia Pipeline Group Inc., a natural gas pipeline, midstream and storage company (“CPG”). The Proposed Separation is expected to occur on July 1, 2015.
Under the plan for the Proposed Separation, NiSource shareholders would retain their current shares of NiSource stock and receive a pro rata distribution of shares of CPG stock in a transaction that is expected to be tax-free to NiSource and its shareholders.
2.    Recent Accounting Pronouncements

In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 clarifies guidance on determining whether a cloud computing arrangement contains a software license that should be accounted for as internal-use software. NiSource is required to adopt ASU 2015-05 for periods beginning after December 15, 2015, including interim periods, and the guidance is permitted to be applied either (1) prospectively to all agreements entered into or materially modified after the effective date or (2) retrospectively, with early adoption permitted. NiSource is currently evaluating the impact the adoption of ASU 2015-05 will have on the Condensed Consolidated Financial Statements (unaudited) or Notes to Condensed Consolidated Financial Statements (unaudited).

In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 changes the way entities present debt issuance costs in financial statements by presenting issuance costs on the balance sheet as a direct deduction from the related debt liability rather than as a deferred charge. Amortization of these costs will continue to be reported as interest expense. NiSource is required to adopt ASU 2015-03 for periods beginning after December 15, 2015, including interim periods, and the guidance is to be applied retrospectively with early adoption permitted. NiSource is currently evaluating the impact the adoption of ASU 2015-03 will have on the Condensed Consolidated Financial Statements (unaudited) or Notes to Condensed Consolidated Financial Statements (unaudited).

In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. ASU 2015-02 amends consolidation guidance by including changes to the variable and voting interest models used by entities to evaluate whether an entity should be consolidated. NiSource is required to adopt ASU 2015-02 for periods beginning after December 15, 2015, including interim periods, and the guidance is to be applied retrospectively or using a modified retrospective approach, with early adoption permitted. NiSource is currently evaluating the impact the adoption of ASU 2015-02 will have on the Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited).

3.    Columbia Pipeline Partners LP (CPPL)

On December 5, 2007, NiSource formed CPPL (the "Partnership") (NYSE: CPPL) to own, operate and develop a portfolio of pipelines, storage and related assets.

On February 11, 2015, CPPL completed its IPO of 53.8 million common units representing limited partnership interests, constituting 53.5% of the Partnership's outstanding limited partnership interests. The Partnership received $1,168.4 million of net proceeds from the IPO. NiSource, through CPG, owns the general partner of the Partnership, all of the Partnership's subordinated units and the incentive distribution rights. The assets of the Partnership consist of a 15.7 percent limited partner interest in Columbia OpCo, which consists of substantially all of the Columbia Pipeline Group Operations segment. The operations of the Partnership will be consolidated in NiSource's results as long as the Partnership remains a subsidiary. If the Proposed Separation occurs, CPG would no longer be a subsidiary of NiSource and, thus, NiSource would cease to own (a) any interest in Columbia OpCo, (b) the general partner of the Partnership, (c) any of the limited partner interests in the Partnership or (d) any of the incentive distribution rights in the Partnership. As of March 31, 2015, the portion of CPPL owned by the public is reflected as a noncontrolling interest in the Condensed Consolidated Financial Statements (unaudited).
The table below summarizes the effects of the changes in NiSource's ownership interest in Columbia OpCo on equity:

The Partnership maintains a $500.0 million revolving credit facility, of which $50.0 million is available for issuance of letters of credit. The purpose of the facility is to provide cash for general partnership purposes, including working capital, capital expenditures and the funding of capital calls. At March 31, 2015, CPPL had no outstanding borrowings under this facility.

4.    Earnings Per Share

Basic EPS is computed by dividing net income attributable to NiSource by the weighted-average number of shares of common stock outstanding for the period. The weighted average shares outstanding for diluted EPS includes the incremental effects of the various long-term incentive compensation plans. The numerator in calculating both basic and diluted EPS for each period is reported net income attributable to NiSource. The computation of diluted average common shares follows:

5.    Gas in Storage
Both the LIFO inventory methodology and the weighted average cost methodology are used to value natural gas in storage. Gas Distribution Operations price natural gas storage injections at the average of the costs of natural gas supply purchased during the year. For interim periods, the difference between current projected replacement cost and the LIFO cost for quantities of gas temporarily withdrawn from storage is recorded as a temporary LIFO liquidation credit or debit within the Condensed Consolidated Balance Sheets (unaudited). Due to seasonality requirements, NiSource expects interim variances in LIFO layers to be replenished by year-end. NiSource had a temporary LIFO liquidation debit of $25.3 million and zero as of March 31, 2015 and December 31, 2014, respectively, for certain gas distribution companies recorded within “Prepayments and other,” on the Condensed Consolidated Balance Sheets (unaudited).

6.    Asset Retirement Obligations
Certain costs of removal that have been, and continue to be, included in depreciation rates and collected in the service rates of the rate-regulated subsidiaries are classified as “Regulatory liabilities” on the Condensed Consolidated Balance Sheets (unaudited).

Changes in NiSource’s liability for asset retirement obligations for the three months ended March 31, 2015 and 2014 are presented in the table below:

7.    Regulatory Matters
Gas Distribution Operations Regulatory Matters

Significant Rate Developments. On November 25, 2014, Columbia of Ohio filed a Notice of Intent to file an application to adjust rates associated with its IRP and DSM Riders. Columbia of Ohio filed its Application on February 27, 2015, and requested authority to increase revenues by $24.7 million. On March 26, 2015, PUCO Staff filed Comments recommending that the PUCO approve Columbia of Ohio’s application in full. On April 22, 2015, the PUCO issued an Order that approved Columbia of Ohio's application.

On March 19, 2015, Columbia of Pennsylvania filed a base rate case with the Pennsylvania PUC, seeking a revenue increase of $46.2 million annually. The case is driven by Columbia of Pennsylvania’s capital investment program which exceeds $197.0 million in 2015 and $211.0 million in 2016 as well as costs to train and comply with pipeline safety-related operation and maintenance expenditures. Columbia of Pennsylvania's request for rate relief includes the recovery of costs that are projected to be incurred after the implementation of new rates, as authorized by the Pennsylvania General Assembly with the passage of Act 11 of 2012. New rates are expected to go into effect during the fourth quarter of 2015.

On April 16, 2015, Columbia of Massachusetts filed a base rate case with the Massachusetts DPU. The case, which seeks increased annual revenues of approximately $49.0 million, is designed to support the company'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. An order in the proceeding is expected on February 29, 2016 with new rates effective March 1, 2016.

On April 30, 2014, Columbia of Virginia filed a base rate case with the VSCC seeking an annual revenue increase of $31.8 million, which includes $6.9 million in annual revenues currently collected as a separate infrastructure replacement rider on customers’ bills under the Virginia SAVE Plan Act. On December 10, 2014, Columbia of Virginia presented at hearing a Stipulation and Proposed Recommendation (“Stipulation”) executed by certain parties to the rate proceeding, including the Staff of the VSCC and the Division of Consumer Counsel of the Office of the Attorney General of the Commonwealth of Virginia. The Stipulation includes

14

Table of Contents
ITEM 1. FINANCIAL STATEMENTS (continued)
NiSource Inc.
Notes to Condensed Consolidated Financial Statements (unaudited) (continued)

a base revenue increase of $25.2 million, recovery of costs related to the implementation of pipeline safety programs, and the proposed change to thermal billing. On January 13, 2015, the Hearing Examiner issued a report that recommended that the VSCC approve the Stipulation. On March 30, 2015, the VSCC issued an Order Remanding for Further Action. In the Order, the VSCC found the revenue increase of $25.2 million and apportionment of that increase between rate classes contained in the Stipulation reasonable. However, the VSCC remanded back to the Hearing Examiner for further proceedings the manner in which fixed costs are to be assigned to the fixed customer charges of each rate class.

Cost Recovery and Trackers. A significant portion of the distribution companies' revenue is related to the recovery of gas costs, the review and recovery of which occurs via standard regulatory proceedings. All states 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 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 via 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 tracking mechanisms include GCR adjustment mechanisms, tax riders, and bad debt recovery mechanisms.

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 bad debt expense. 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 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.

NIPSCO has approval from the IURC to recover certain costs for gas transmission, distribution and storage system improvements. On February 27, 2015, NIPSCO filed gas TDSIC-2 which included $43.3 million of net capital expenditures for the period ended December 31, 2014.

Columbia Pipeline Group Operations Regulatory Matters

Columbia Transmission Customer Settlement. In January 2015, Columbia Pipeline Group Operations commenced the third year of the Columbia Transmission long-term system modernization program. The Columbia Pipeline Group Operations segment expects to invest approximately $300.0 million in modernization investments during 2015. Recovery of approximately $320.0 million of investments made in 2014 began on February 1, 2015.

Cost Recovery Trackers. A significant portion of the transmission and storage regulated companies' revenue is related to the recovery of their operating costs, the review and recovery of which occurs via standard regulatory proceedings with the FERC under section 4 of the Natural Gas Act. However, certain operating costs of the NiSource regulated transmission and storage companies are significant and recurring in nature, such as fuel for compression and lost and unaccounted for gas. The FERC allows for the recovery of such costs via cost tracking mechanisms. These tracking mechanisms allow the transmission and storage companies' rates to fluctuate in response to changes in certain operating costs or conditions as they occur to facilitate the timely recovery of its costs incurred. The tracking mechanisms involve a rate adjustment that is filed at a predetermined frequency, typically annually, with the FERC and is subject to regulatory review before new rates go into effect. Other such costs under regulatory tracking mechanisms include upstream pipeline transmission, electric compression, operational purchases and sales of natural gas, and the revenue requirement for capital investments made under Columbia Transmission's long-term plan to modernize its interstate transmission system as discussed above.

Electric Operations Regulatory Matters

Significant Rate Developments. On July 19, 2012 and December 19, 2012, the FERC issued orders approving construction work in progress in rate base and abandoned plant cost recovery requested by NIPSCO for a 100-mile, 345 kV transmission project and its right to develop 50 percent of the 66-mile, 765 kV project. NIPSCO began recording revenue in the first quarter of 2013 using a forward looking rate, based on an average construction work in progress balance. For the three months ended March 31, 2015 and 2014, revenue of $5.3 million and $2.1 million, respectively, was recorded.

On July 19, 2013, NIPSCO filed its electric TDSIC with the IURC. The filing included the seven-year plan of eligible investments for a total of approximately $1.1 billion with the majority of the spend occurring in years 2016 through 2020. On February 17, 2014, the IURC issued an order approving NIPSCO’s seven-year plan of eligible investments. The Order also granted NIPSCO ratemaking relief associated with the eligible investments through a rate adjustment mechanism. The NIPSCO Industrial Group and the OUCC have filed Notices of Appeal with the Indiana Court of Appeals in response to the IURC's ruling. On November 25, 2014, NIPSCO’s requested TDSIC factors were approved on an interim basis and subject to refund, pending the outcome of the appeals of the IURC’s February 17, 2014 Orders. On April 8, 2015, the Court of Appeals issued an Order concluding that the IURC erred in approving NIPSCO’s seven-year plan given its lack of detail regarding the projects for years two through seven. The Court then remanded the decision to the IURC. The April 8, 2015 Order is final after the expiration of 30 days if no parties petition for transfer to the Supreme Court. However, if a party petitions for transfer to the Supreme Court, the Order is not final until completion of the appellate process. NIPSCO is reviewing this decision and evaluating its options and does not believe the impact is material to the Condensed Consolidated Financial Statements (unaudited).

Cost Recovery and Trackers. A significant 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 standard, quarterly, “summary” regulatory proceeding in Indiana.

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 via 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.

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 through an ECRM and (2) related operation and maintenance and depreciation expenses once the environmental facilities become operational through an EERM.

On April 22, 2015, the IURC issued an order on ECR-25 approving NIPSCO's request to begin earning a return on $734.1 million of net capital expenditures for the period ended December 31, 2014. The order also approved a revised capital cost estimate of $264.8 million for its Phase III multi-pollutant compliance plan projects related to the Unit 12 FGD, an increase from the previous IURC approved cost estimate of $246.3 million.

NIPSCO has approval from the IURC to recover certain costs for transmission and distribution system improvements through the electric TDSIC. On November 25, 2014, the IURC approved, on an interim basis and subject to refund pending the outcome of appeals, NIPSCO’s requested TDSIC factors associated with the eligible investments, which included $19.4 million of net capital expenditures for the period ended June 30, 2014. On February 26, 2015, NIPSCO filed electric TDSIC-2 which included $62.3 million of net capital expenditures for the period ended December 31, 2014. See further discussion regarding the electric TDSIC above.

Price risk management assets and liabilities primarily include NYMEX futures and NYMEX options which are commodity exchange-traded and non-exchange-based derivative 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 in 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 in 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 March 31, 2015 and December

31, 2014, there were 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.
Commodity price risk resulting from derivative activities at NiSource’s rate-regulated subsidiaries is limited, since regulations allow recovery of prudently incurred purchased power, fuel and gas costs through the ratemaking process, including gains or losses on these derivative instruments. If states should explore additional regulatory reform, these subsidiaries may begin providing services without the benefit of the traditional ratemaking process and may be more exposed to commodity price risk. Some of NiSource’s rate-regulated utility subsidiaries offer commodity price risk products to its customers for which derivatives are used to hedge forecasted customer usage under such products. These subsidiaries do not have regulatory recovery orders for these products and are subject to gains and losses recognized in earnings due to hedge ineffectiveness.
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 Condensed Consolidated Balance Sheets (unaudited). Securities classified within Level 1 include U.S. Treasury debt securities which are highly liquid and are actively traded in over-the-counter markets. NiSource values corporate and mortgage-backed debt 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). The amortized cost, gross unrealized gains and losses, and fair value of available-for-sale debt securities at March 31, 2015 and December 31, 2014 were:

For the three months ended March 31, 2015 and 2014, the net realized gain on the sale of available-for-sale U.S. Treasury debt securities was zero and $0.1 million, respectively. For the three months ended March 31, 2015 and 2014, the net realized gain on the sale of available-for-sale Corporate/Other bond debt securities was zero and $0.1 million, respectively.
The cost of maturities sold is based upon specific identification. At March 31, 2015, approximately $4.5 million of U.S. Treasury debt securities have maturities of less than a year while the remaining securities have maturities of greater than one year. At March 31, 2015, approximately $5.0 million of Corporate/Other bonds 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 three months ended March 31, 2015 and 2014.
 
 
Non-recurring Fair Value Measurements. There were no significant non-recurring fair value measurements recorded during the three months ended March 31, 2015.

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 issues or on the rates offered for securities of the same remaining maturities. Certain premium costs associated with the early settlement of long-term debt are not taken into consideration in determining fair value. These fair value measurements are classified as Level 2 within the fair value hierarchy. For the three months ended March 31, 2015 and 2014, there were no changes in the method or significant assumptions used to estimate the fair value of the financial instruments.

9.    Transfers of Financial Assets
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term borrowings on the Condensed Consolidated Balance Sheets (unaudited). The maximum amount of debt that can be recognized related to NiSource’s accounts receivable programs is $515 million.

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. Below is information about the accounts receivable securitization agreements entered into by NiSource’s subsidiaries

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 commercial paper conduits sponsored by BTMU and BNS. This agreement was last renewed on October 17, 2014; the current agreement expires on October 16, 2015 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 March 31, 2015, no accounts receivable had been transferred by CGORC. CGORC is a separate corporate entity from NiSource and Columbia of Ohio, with its own 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 a commercial paper conduit sponsored by Mizuho. This agreement was last renewed on August 27, 2014; the current agreement expires on August 26, 2015 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 March 31, 2015, $200.0 million of accounts receivable had been transferred by NARC. NARC is a separate corporate entity from NiSource and NIPSCO, with its own 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 10, 2015, having a current scheduled termination date of March 9, 2016 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 March 31, 2015, $75.0 million of accounts receivable had been transferred by CPRC. CPRC is a separate corporate entity from NiSource and Columbia of Pennsylvania, with its own 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.

10.    Goodwill
 
NiSource tests its goodwill for impairment annually as of May 1 unless indicators, events, or circumstances would require an immediate review. Goodwill is tested for impairment using financial information at the reporting unit level, which is consistent with the level of discrete financial information reviewed by operating segment management. NiSource's three reporting units are Columbia Distribution Operations, Columbia Transmission Operations and NIPSCO Gas Distribution Operations.

NiSource applied the qualitative step 0 analysis to its reporting units for the annual impairment test performed as of May 1, 2014. The results of this assessment indicated that it is not more likely than not that its reporting unit fair values are less than the reporting unit carrying values.

NiSource considered whether there were any events or changes in circumstances subsequent to the annual test that would reduce the fair value of any of the reporting units below their carrying amounts and necessitate another goodwill impairment test. No such indicators were noted that would require a subsequent goodwill impairment testing during the first quarter of 2015.

 
11.    Income Taxes
NiSource’s interim effective tax rates reflect the estimated annual effective tax rates for 2015 and 2014, adjusted for tax expense associated with certain discrete items. The effective tax rates for the three months ended March 31, 2015 and 2014 were 35.4% and 37.9%, respectively. These effective tax rates differ from the Federal tax rate of 35% primarily due to the effects of tax credits, state income taxes, utility ratemaking, and other permanent book-to-tax differences. The decrease in the three month effective tax rate of 2.5% in 2015 versus 2014 is primarily due to the impact of the Indiana rate change in 2014.

There were no material changes recorded in 2015 to NiSource's uncertain tax positions as of December 31, 2014.

12.    Pension and Other Postretirement Benefits

NiSource provides defined contribution plans and noncontributory defined benefit retirement plans that cover 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.

For the three months ended March 31, 2015, NiSource has contributed $0.7 million to its pension plans and $8.7 million to its other postretirement benefit plans.

13.    Variable Interests and Variable Interest Entities
In general, a VIE is an entity that (1) has an insufficient amount of at-risk equity to permit the entity to finance its activities without additional financial subordinated support provided by any parties, (2) whose at-risk equity owners, as a group, do not have power, through voting rights or similar rights, to direct activities of the entity that most significantly impact the entity’s economic performance or (3) whose at-risk owners do not absorb the entity’s losses or receive the entity’s residual return. A VIE is required to be consolidated by a company if that company is determined to be the primary beneficiary of the VIE.
NiSource consolidates those VIEs for which it is the primary beneficiary. NiSource considers quantitative and qualitative elements in determining the primary beneficiary. Qualitative measures include the ability to control an entity and the obligation to absorb losses or the right to receive benefits.
NiSource’s analysis includes an assessment of guarantees, operating leases, purchase agreements, and other contracts, as well as its investments and joint ventures. For items that have been identified as variable interests, or where there is involvement with an identified VIE, an in-depth review of the relationship between the relevant entities and NiSource is made to evaluate qualitative and quantitative factors to determine the primary beneficiary, if any, and whether additional disclosures would be required under the current standard.
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. 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 $5.6 million and $5.4 million for the three months ended March 31, 2015 and 2014, respectively. 

14.    Short-Term Borrowings
NiSource Finance maintains a $2.0 billion revolving credit facility with a syndicate of banks led by Barclays Capital with a termination date of September 28, 2018. The purpose of the facility is to fund ongoing working capital requirements including the provision of liquidity support for NiSource’s $1.5 billion commercial paper program, provide for issuance of letters of credit, and also for general corporate purposes. At March 31, 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, RBS and Wells Fargo. Commercial paper issuances are supported by available capacity under NiSource’s $2.0 billion unsecured revolving credit facility. At March 31, 2015, NiSource had $39.0 million of commercial paper outstanding.
As of March 31, 2015 and December 31, 2014, NiSource had $30.9 million of stand-by letters of credit outstanding of which $14.7 million were under the revolving credit facility.

CPPL maintains a $500.0 million revolving credit facility, of which $50.0 million is available for issuance of letters of credit. The purpose of the facility is to provide cash for general partnership purposes, including working capital, capital expenditures and the funding of capital calls. At March 31, 2015, CPPL had no outstanding borrowings under this facility.
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term borrowings on the Condensed Consolidated Balance Sheets (unaudited) in the amount of $275.0 million and $284.3 million as of March 31, 2015 and December 31, 2014, respectively.

15.    Share-Based Compensation

The stockholders approved and adopted the NiSource Inc. 2010 Omnibus Incentive Plan (the “Omnibus Plan”), at the Annual Meeting of Stockholders held on May 11, 2010. The Omnibus Plan provides for awards to employees and non-employee directors of incentive and nonqualified stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares, performance units, cash-based awards and other stock-based awards. 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 granted under either the long-term incentive plan approved by stockholders on April 13, 1994 ("1994 Plan") or the Director Stock Incentive Plan ("Director Plan"), that expire or terminate for any reason. No further awards are permitted to be granted under the 1994 Plan or the Director Plan. At March 31, 2015, there were 5,785,224 shares reserved for future awards under the Omnibus Plan.
NiSource recognized stock-based employee compensation expense of $11.2 million and $5.3 million for the three months ended March 31, 2015 and 2014, respectively, as well as related tax benefits of $4.0 million and $2.0 million, respectively.
As of March 31, 2015, the total remaining unrecognized compensation cost related to nonvested awards amounted to $35.8 million, which will be amortized over the weighted-average remaining requisite service period of 2.3 years.
Restricted Stock Units and Restricted Stock. During the three months ended March 31, 2015, NiSource granted 486,523 restricted stock units and shares of restricted stock, subject to service conditions. The total grant date fair value of restricted stock units and shares of restricted stock was $19.4 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, net of forfeitures, over the vesting period which is generally three years. As of March 31, 2015, 723,406 nonvested (all of which are expected to vest) restricted stock units and shares of restricted stock were granted and outstanding.
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 common stock. NiSource also has a retirement savings plan that provides for discretionary profit sharing contributions payable in shares of common stock to eligible employees based on earnings results; and eligible exempt employees hired after January 1, 2010, receive a non-elective company contribution of three percent of eligible pay payable in shares of common stock. For the quarters ended March 31, 2015 and 2014, NiSource recognized 401(k) match, profit sharing and non-elective contribution expense of $8.2 million and $8.5 million, respectively.

16.    Other Commitments and Contingencies
A.    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. The total guarantees and indemnities in existence at March 31, 2015 and the years in which they expire were:

Guarantees of Subsidiaries Debt. NiSource has guaranteed the payment of $7,960.5 million of debt for various wholly-owned subsidiaries including NiSource Finance and Columbia of Massachusetts, and through a support agreement for Capital Markets, which is reflected on NiSource’s Condensed Consolidated Balance Sheets (unaudited). The subsidiaries are required to comply with certain covenants under the debt indenture and in the event of default, NiSource would be obligated to pay the debt’s principal and related interest. NiSource does not anticipate its subsidiaries will have any difficulty maintaining compliance. On October 3, 2011, NiSource executed a Second Supplemental Indenture to the original Columbia of Massachusetts Indenture dated April 1, 1991, for the specific purpose of guaranteeing Columbia of Massachusetts’ outstanding unregistered medium-term notes.
Lines and Letters of Credit and Accounts Receivable Advances. NiSource Finance maintains a $2.0 billion revolving credit facility with a syndicate of banks led by Barclays Capital with a termination date of September 28, 2018. The purpose of the facility is to fund ongoing working capital requirements including the provision of liquidity support for NiSource’s $1.5 billion commercial paper program, provide for issuance of letters of credit, and also for general corporate purposes. At March 31, 2015, NiSource had no borrowings under its five-year revolving credit facility, $39.0 million in commercial paper outstanding and $275.0 million outstanding under its accounts receivable securitization agreements. At March 31, 2015, NiSource had issued stand-by letters of credit of approximately $30.9 million for the benefit of third parties. See Note 14 for additional information.
CPPL maintains a $500.0 million revolving credit facility, of which $50.0 million is available for issuance of letters of credit. The purpose of the facility is to provide cash for general partnership purposes, including working capital, capital expenditures and the funding of capital calls. At March 31, 2015, CPPL had no outstanding borrowings under this facility.
Other Guarantees or Obligations. NiSource has purchase and sales agreement guarantees totaling $25.6 million, which guarantee purchaser performance or seller performance under covenants, obligations, liabilities, representations or warranties under the agreements. No amounts related to the purchase and sale agreement guarantees are reflected in the Condensed Consolidated Balance Sheets (unaudited). Management believes that the likelihood NiSource would be required to perform or otherwise incur any significant losses associated with any of the aforementioned guarantees is remote.

NiSource has on deposit a letter of credit with Union Bank, N.A., Collateral Agent, in a debt service reserve account in association with Millennium's notes as required under the Deposit and Disbursement Agreement that governs the Millennium notes. This account is to be drawn upon by the note holders in the event that Millennium is delinquent on its principal and interest payments. The value of NiSource’s letter of credit represents 47.5% (NiSource’s ownership interest in Millennium) of the debt service reserve account requirement, or $16.2 million. The total exposure for NiSource is $16.2 million. NiSource has an accrued liability of $1.5 million related to the inception date fair value of this guarantee as of March 31, 2015.
B.    Other Legal Proceedings. In the normal course of its business, NiSource and its subsidiaries have been named as defendants in various legal proceedings. In the opinion of management, the ultimate disposition of these currently asserted claims will not have a material impact on NiSource’s consolidated financial statements.

C.    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 those environmental regulations currently applicable to its operations and believes that it has all necessary permits to conduct 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 March 31, 2015 and December 31, 2014, NiSource had recorded an accrual of approximately $128.3 million and $128.4 million, respectively, to cover environmental remediation at various sites. The current portion of this accrual is included in "Legal and environmental" in the Condensed Consolidated Balance Sheets (unaudited). The noncurrent portion is included in "Other noncurrent liabilities" in the Condensed Consolidated Balance Sheets (unaudited). NiSource accrues for 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 cleanup can 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 contamination, the method of cleanup, and the availability of cost recovery from customers. These expenditures are not currently estimable at some sites. NiSource periodically adjusts its accrual as information is collected and estimates become more refined.
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 could significantly restrict emissions of GHGs or could impose a cost or tax on GHG emissions.

On June 2, 2014, the EPA proposed a GHG performance standard for existing fossil-fuel fired electric utility generating units under section 111(d) of the Clean Air Act. The proposed rule establishes state-specific CO2 emission rate goals, applied to the state's fleet of fossil-fuel fired electric generating units, and requires each state to submit a plan indicating how the state will meet the EPA's emission rate goal, including possibly imposing reduction obligations on specific units. Final CO2 emission rate standards are expected to be set by the EPA by midsummer 2015, and state plans are required to be submitted to the EPA as early as June 2016. The cost to comply with this rule will depend on a number of factors, including the requirements of the final federal regulation and the level of NIPSCO's required GHG 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. NiSource will continue to monitor this matter and cannot estimate its impact at this time.
National Ambient Air Quality Standards. The CAA requires the EPA to set NAAQS for particulate matter and five other pollutants considered harmful to public health and the environment. Periodically the EPA imposes new or modifies existing NAAQS. States that contain areas that do not meet the new or revised standards must take steps to maintain or achieve compliance with the standards. These steps could include additional pollution controls on boilers, engines, turbines, and other facilities owned by electric generation, gas distribution, and gas transmission operations.
The following NAAQS were recently added or modified:
Ozone: On November 25, 2014, the EPA proposed to lower the 8-hour ozone standard from 75 ppb to within a range of 65-70 ppb. If the standard is finalized and the EPA proceeds with designations, areas where NiSource operates currently designated as attainment may be re-classified as non-attainment. NiSource will continue to monitor this matter and cannot estimate its impact at this time.
Nitrogen Dioxide (NO2): The EPA revised the NO2 NAAQS by adding a one-hour standard while retaining the annual standard. The new standard could impact some NiSource combustion sources. The EPA designated all areas of the country as unclassifiable/attainment in January 2012. After the establishment of a new monitoring network and possible modeling implementation, areas will potentially be re-designated sometime in 2016. States with areas that do not meet the standard will be required to develop rules to bring areas into compliance within five years of designation. Additionally, under certain permitting circumstances, emissions from some existing NiSource combustion sources may need to be assessed and mitigated. NiSource will continue to monitor this matter and cannot estimate the impact of these rules at this time.

Waste
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 cleanup liabilities, associated with certain former operations.
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 66 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 liability were noted as a result of the refresh completed as of June 30, 2014. The total estimated liability at NiSource related to the facilities subject to remediation was $120.3 million and $121.5 million at March 31, 2015 and December 31, 2014, 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.
Additional Issues Related to Individual Business Segments

The sections below describe various regulatory actions that affect individual business segments for which NiSource has retained a liability.
Electric Operations.
Air
NIPSCO is subject to a number of air-quality mandates in the next several years. These mandates required NIPSCO to make capital improvements to its electric generating stations. The cost of capital improvements is estimated to be $870 million, of which approximately $107.3 million remains to be spent. This figure includes additional capital improvements associated with the New Source Review Consent Decree and the Utility Mercury and Air Toxics Standards Rule. NIPSCO believes that the capital costs will likely be recoverable from customers.

Utility Mercury and Air Toxics Standards Rule: On December 16, 2011, the EPA finalized the MATS rule establishing new emissions limits for mercury and other air toxics. NIPSCO’s affected units have completed projects to meet the April 2015 compliance deadline. For NIPSCO’s remaining affected units, a one year compliance extension granted by IDEM delays the compliance date until April 2016. NIPSCO continues to implement an IURC-approved plan for the installation of additional environmental controls needed to comply with the MATS extension.

Water
On August 15, 2014, the EPA published the final Phase II Rule of the Clean Water Act Section 316(b), which requires all large existing steam electric generating stations to meet certain performance standards to reduce the effects on aquatic organisms at their cooling water intake structures. Under this rule, stations will have to either demonstrate that the performance of their existing fish protection systems meet the new standards or develop new systems, such as a closed-cycle cooling tower. The cost to comply will depend on a number of factors, including evaluation of the various compliance options available under the regulation and permitting-related determinations by IDEM. NIPSCO is currently evaluating these options and cannot estimate the cost of compliance at this time.

On June 7, 2013, the EPA published a proposed rule to amend the effluent limitations guidelines and standards for the Steam Electric Power Generating category. These proposed regulations could impose new water treatment requirements on NIPSCO’s electric generating facilities. NIPSCO will continue to monitor developments in this matter and cannot estimate the cost of compliance at this time.

Waste
On April 17, 2015, the EPA released a final rule for regulation of CCRs. The rule regulates CCRs under the Resource Conservation and Recovery Act Subtitle D, which determines them to be non-hazardous. It will require increased groundwater monitoring, reporting, recordkeeping, and posting related information to the Internet. The rule also establishes requirements related to CCR management, impoundments, landfills and storage. NIPSCO will have to modify its infrastructure and management of CCRs under this rule. The rule will allow NIPSCO to continue its byproduct beneficial use program. NIPSCO is currently evaluating the rule and cannot estimate the cost of compliance at this time.

D.     Other Matters.

Transmission Upgrade Agreements. On February 11, 2014, NIPSCO entered into two TUAs with upgrade sponsors to complete upgrades on NIPSCO’s transmission system on behalf of those sponsors. The upgrade sponsors have 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. The FERC set for hearing the issue of what constitutes the incremental costs NIPSCO will incur, but is holding that hearing in abeyance to allow for settlement. NIPSCO will continue to monitor developments in this matter and does not believe the impact is material to the Condensed Consolidated Financial Statements (unaudited).

Springfield, Massachusetts. On November 23, 2012, while Columbia of Massachusetts was investigating the source of an odor of gas at a service location in Springfield, Massachusetts, a gas service line was pierced and an explosion occurred. While this explosion impacted multiple buildings and resulted in several injuries, no life threatening injuries or fatalities have been reported. Columbia of Massachusetts is fully cooperating with both the Massachusetts DPU and the Occupational Safety & Health Administration in their investigations of this incident. Columbia of Massachusetts believes any costs associated with damages, injuries, and other losses related to this incident are substantially covered by insurance. Any amounts not covered by insurance are not expected to have a material impact on NiSource's consolidated financial statements. In accordance with GAAP, NiSource recorded any accruals and the related insurance recoveries resulting from this incident on a gross basis within the Condensed Consolidated Balance Sheets (unaudited).

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
NiSource Inc.

Note regarding forward-looking statements
The Management’s Discussion and Analysis, including statements regarding market risk sensitive instruments, contains “forward-looking statements,” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Investors and prospective investors should understand that many factors govern whether any forward-looking statement contained herein will be or can be realized. Any one of those factors could cause actual results to differ materially from those projected. These forward-looking statements include, but are not limited to, statements concerning NiSource’s plans, objectives, expected performance, expenditures, recovery of expenditures through rates, stated on either a consolidated or segment basis, the Proposed Separation and any and all underlying assumptions and other statements that are other than statements of historical fact. From time to time, NiSource may publish or otherwise make available forward-looking statements of this nature. All such subsequent forward-looking statements, whether written or oral and whether made by or on behalf of NiSource, are also expressly qualified by these cautionary statements. All forward-looking statements are based on assumptions that management believes to be reasonable; however, there can be no assurance that actual results will not differ materially.
Factors that could cause actual results to differ materially from the projections, forecasts, estimates and expectations discussed in this Quarterly Report on Form 10-Q include, among other things, weather, fluctuations in supply and demand for energy commodities, growth opportunities for NiSource’s businesses, increased competition in deregulated energy markets, the success of regulatory and commercial initiatives, dealings with third parties over whom NiSource has no control, actual operating experience of NiSource’s assets, the regulatory process, regulatory and legislative changes, the impact of potential new environmental laws or regulations, the results of material litigation, changes in pension funding requirements, changes in general economic, capital and commodity market conditions, counterparty credit risk, the timing to consummate the Proposed Separation; the risk that a condition to the Proposed Separation is not satisfied; disruption to operations as a result of the Proposed Separation, the inability of one or more of the businesses to operate independently following the completion of the Proposed Separation and the matters set forth in the “Risk Factors” section of NiSource’s 2014 Form 10-K and this Form 10-Q, many of which are beyond the control of NiSource. In addition, the relative contributions to profitability by each segment, and the assumptions underlying the forward-looking statements relating thereto, may change over time. NiSource expressly disclaims any duty to update any of the forward-looking statements contained in this report.
The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with NiSource’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014.


CONSOLIDATED REVIEW

Planned Separation of Columbia Pipeline Group and Initial Public Offering of Columbia Pipeline Partners LP
On September 28, 2014, NiSource (the “Company”) announced that its Board of Directors had approved in principle plans to separate its natural gas pipeline and related businesses into a stand-alone publicly traded company (the “Proposed Separation”). If completed, the Proposed Separation will result in two energy infrastructure companies: NiSource Inc., a fully regulated natural gas and electric utilities company, and Columbia Pipeline Group Inc., a natural gas pipeline, midstream and storage company (“CPG”). The Proposed Separation is expected to occur on July 1, 2015.
Under the plan for the Proposed Separation, NiSource stockholders would retain their current shares of NiSource stock and receive a pro rata distribution of shares of CPG stock in a transaction that is expected to be tax-free to NiSource and its stockholders for U.S. federal income tax purposes.
The Proposed Separation is subject to various conditions, including, without limitation, the receipt by NiSource of a legal opinion on the tax-free nature of the distribution and final approval of the NiSource Board of Directors. NiSource shareholder approval of the transaction is not required. There is no assurance that the transaction will be completed on July 1, 2015 or at all.
In addition, prior to the Proposed Separation, CPG expects to issue its own long-term notes and use the proceeds from that offering to repay intercompany debt and pay a special dividend to NiSource, which plans to use the special dividend to reduce its net debt prior to the Proposed Separation.
On February 11, 2015, CPPL completed its IPO of 53.8 million common units representing limited partnership interests, constituting 53.5% of the Partnership's outstanding limited partnership interests. The Partnership received $1,168.4 million of net proceeds

NiSource Inc.


from the IPO. NiSource, through CPG, owns the general partner of the Partnership, all of the Partnership's subordinated units and the incentive distribution rights. The assets of the Partnership consist of a 15.7 percent limited partner interest in Columbia OpCo, which consists of substantially all of the Columbia Pipeline Group Operations segment. The operations of the Partnership will be consolidated in NiSource's results as long as the Partnership remains a subsidiary. If the Proposed Separation occurs, CPG would no longer be a subsidiary of NiSource and, thus, NiSource would cease to own (a) any interest in Columbia OpCo, (b) the general partner of the Partnership, (c) any of the limited partner interests in the Partnership or (d) any of the incentive distribution rights in the Partnership.
Executive Summary
NiSource is an energy holding company under the Public Utility Holding Company Act of 2005 whose subsidiaries are engaged in the transmission, storage and distribution of natural gas in the high-demand energy corridor stretching from the Gulf Coast through the Midwest to New England and the generation, transmission and distribution of electricity in Indiana. NiSource generates substantially all of its operating income through these rate-regulated businesses. A significant portion of NiSource’s operations is subject to seasonal fluctuations in sales. During the heating season, which is primarily from November through March, net revenues from gas sales are more significant, and during the cooling season, which is primarily from June through September, net revenues from electric sales and transportation services are more significant, than in other months.
For the three months ended March 31, 2015, net income attributable to NiSource was $268.4 million, or $0.85 per basic share, compared to $266.2 million, or $0.85 per basic share reported for the same period in 2014.
The increase in net income attributable to NiSource was due primarily to the following items:
Regulatory and service programs at Gas Distribution Operations increased net revenues by $33.2 million primarily due to the impacts of the rate cases at Columbia of Pennsylvania, Columbia of Virginia and Columbia of Massachusetts, as well as the implementation of rates under Columbia of Ohio's approved infrastructure replacement program. Refer to Note 7, “Regulatory Matters,” in the Notes to Consolidated Financial Statements included in NiSource's Annual Report on Form 10-K for the fiscal year ended December 31, 2014 for more information.
Demand margin revenue increased by $30.7 million at Columbia Pipeline Group Operations primarily as a result of growth projects placed in service. Refer to the Columbia Pipeline Group Operations' segment discussion for further information on growth projects.
These increases in net income attributable to NiSource were partially offset by the following:
Outside service costs increased by $26.2 million primarily due to costs associated with the Proposed Separation.
Employee and administrative expense increased by $20.4 million due primarily to greater labor expense due to a growing workforce.
These factors and other impacts to the financial results are discussed in more detail within the following discussions of “Results of Operations” and “Results and Discussion of Segment Operations.”
Platform for Growth
NiSource’s business plan will continue to center on commercial and regulatory initiatives, commercial growth and expansion of the gas transmission and storage business, and financial management of the balance sheet.

Commercial and Regulatory Initiatives
NiSource is moving forward on regulatory initiatives across several distribution company markets. Whether through full rate case filings or other approaches, NiSource’s goal is to develop strategies that benefit all stakeholders as it addresses changing customer conservation patterns, develops more contemporary pricing structures, and embarks on long-term investment programs to enhance its infrastructure.

NIPSCO continued to focus on customer service, reliability and long-term growth and modernization initiatives during the first quarter, while executing on significant environmental investments.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)
NiSource Inc.


NIPSCO remains on schedule and on budget with its FGD unit at its Michigan City Generating Station. The approximately $264.8 million project is expected to be placed in service by the end of 2015 along with an additional $80 million in environmental investments at NIPSCO’s coal-fired generating facilities. These investments, supported with cost recovery, help improve air quality and ensure NIPSCO’s generation fleet remains in compliance with current environmental regulations. These investments also help ensure that NIPSCO can continue offering low-cost, reliable and efficient generating capacity for its customers.

Progress also continued on two major NIPSCO electric transmission projects designed to enhance system flexibility and reliability. The Greentown-Reynolds project is a 70-mile, 765-kV line being constructed in a joint development agreement with Pioneer Transmission, and the Reynolds-Topeka project is a 100-mile, 345-kV line. Right-of-way acquisition and permitting are under way for both projects and construction has begun on the Reynolds-Topeka line. The projects involve a NIPSCO investment of approximately $500 million and are anticipated to be in service by the end of 2018.

NiSource's Gas Distribution companies continue to execute their strategy of long-term infrastructure replacement and enhancement and advance their regulatory agenda.

On March 19, 2015, Columbia of Pennsylvania filed a base rate case with the Pennsylvania PUC to support continuation of Columbia of Pennsylvania’s infrastructure modernization and safety programs. If approved as filed, the case would increase annual revenues by $46.2 million. New rates are expected to go into effect during the fourth quarter of 2015.

On April 16, 2015, Columbia of Massachusetts filed a base rate case with the Massachusetts DPU. The case, which seeks increased annual revenues of approximately $49.0 million, is designed to support the company'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. An order in the proceeding is expected on February 29, 2016 with new rates effective March 1, 2016.

Columbia of Virginia’s base rate case remains pending with the VSCC. The case is expected to provide a base rate increase of $25.2 million, including recovery of pipeline safety program costs.

Refer to Note 7, “Regulatory Matters,” in the Notes to Condensed Consolidated Financial Statements (unaudited) for a complete discussion of regulatory and commercial matters.

Modernization, Commercial Growth and Expansion of the Columbia Pipeline Group Operations
Columbia Pipeline Group Operations continues to make progress on its long-term infrastructure modernization program, as well as a series of midstream and core growth initiatives tied to NiSource's asset position in the Utica and Marcellus Shale production regions.

In January 2015, Columbia Pipeline Group Operations commenced the third year of the Columbia Transmission long-term system modernization program. The Columbia Pipeline Group Operations segment expects to invest approximately $300 million in modernization investments during 2015. Recovery of approximately $320 million of investments made in 2014 began on February 1, 2015. A settlement with the company's customers, approved in early 2013, addresses the initial five years of an expected 10 to 15 year program that is expected to exceed $4 billion in investment.

Columbia Pipeline Group Operations segment’s East Side Expansion project will be placed in service in the fourth quarter of 2015. The $275 million project will provide up to 312,000 Dth/d of additional capacity for Marcellus Shale supplies to reach growing and capacity constrained northeastern and mid-Atlantic markets.

Progress continues on several other major growth projects, including Columbia Pipeline Group Operations' approximately $1.8 billion combined investment in the Leach and Rayne XPress projects, the approximate $850 million WB XPress project, the $310 million Cameron Access project, the $50 million Utica Access project, the $33 million Chesapeake LNG project, and the $24 million Kentucky Power Plant project. Together these projects will entail approximately 4 billion cubic feet of new capacity commitments across the Columbia Pipeline Group Operations' system, including access to LNG export facilities in Louisiana and Maryland.

NiSource Inc.


NiSource Midstream also is on budget and schedule with the first phase of its $120 million Washington County Gathering project and its approximately $65 million Big Pine Expansion project. Both are expected to be in service in the third quarter of 2015.

Financial Management of the Balance Sheet
On March 30, 2015, Standard & Poor's affirmed the senior unsecured ratings for NiSource and its subsidiaries at BBB- and the commercial paper rating of A-3. Standard & Poor's outlook for NiSource and all of its subsidiaries is Watch Positive.
On February 11, 2015, CPPL completed its IPO of 53.8 million common units representing limited partnership interests. See additional information at the beginning of this section.
CPPL maintains a $500.0 million revolving credit facility, of which $50.0 million is available for issuance of letters of credit. The purpose of the facility is to provide cash for general partnership purposes, including working capital, capital expenditures and the funding of capital calls. At March 31, 2015, CPPL had no outstanding borrowings under this facility.

In preparation for the Planned Separation, the debt recapitalization process is expected to begin during the second quarter of 2015 and will include CPG issuing its own long-term debt prior to the separation to fund a one-time cash distribution to NiSource, which is to be used, in large part, to reduce NiSource’s net debt.
Ethics and Controls
NiSource has had a long-term commitment to providing accurate and complete financial reporting as well as high standards for ethical behavior by its employees. NiSource’s senior management takes an active role in the development of this Form 10-Q and the monitoring of the company’s internal control structure and performance. In addition, NiSource will continue its mandatory ethics training program for all employees.
For additional information refer to Item 4, “Controls and Procedures.”
Results of Operations
Quarter Ended March 31, 2015
Net Income Attributable to NiSource
NiSource reported net income of $268.4 million, or $0.85 per basic share, for the three months ended March 31, 2015, compared to net income of $266.2 million, or $0.85 per basic share, for the first quarter of 2014. Income from continuing operations was $268.4 million, or $0.85 per basic share, for the three months ended March 31, 2015, compared to income from continuing operations of $266.4 million, or $0.85 per basic share, for the first quarter of 2014. Operating income was $530.1 million, a decrease of $3.6 million from the same period in 2014. All per share amounts are basic earnings per share. Basic average shares of common stock outstanding at March 31, 2015 were 316.6 million compared to 314.2 million at March 31, 2014.
Comparability of line item operating results between quarterly periods is impacted by regulatory and tax trackers that allow for the recovery in rates of certain costs such as bad debt expense. Therefore, increases in these tracked operating expenses are offset by increases in net revenues and have essentially no impact on income from continuing operations.
Net Revenues
Total consolidated net revenues (gross revenues less cost of sales) for the quarter ended March 31, 2015, were $1,343.7 million, an $84.5 million increase from the same period last year. This increase in net revenues was primarily due to increased Gas Distribution Operations' net revenues of $91.1 million, offset by a decrease in Columbia Pipeline Group Operations' net revenues of $5.8 million.
Gas Distribution Operations’ net revenues increased due primarily to an increase in regulatory and tax trackers, which are offset in expense, of $50.6 million and an increase of $33.2 million for regulatory and service programs, including the impacts of rate cases at Columbia of Pennsylvania, Columbia of Virginia and Columbia of Massachusetts, as well as the implementation of rates under Columbia of Ohio's approved infrastructure replacement program. Additionally, there was higher revenue of $5.3 million resulting from the prior year reduction in revenue from NIPSCO's GCIM.

33

Table of Contents

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)
NiSource Inc.


These increases to net revenues were partially offset by the following:
Columbia Pipeline Group Operations’ net revenues decreased due primarily to lower regulatory trackers, which are offset in expense, of $27.4 million and other miscellaneous decreases of $9.1 million. These decreases were partially offset by increased demand margin revenue of $30.7 million as a result of growth projects placed in service and new firm contracts.
Operating Expenses
Operating expenses for the first quarter of 2015 were $829.0 million, an increase of $93.7 million from the 2014 period. This increase was primarily due to higher operation and maintenance expenses of $72.9 million, increased depreciation and amortization of $8.8 and a decrease in the gain on the sale of assets of $10.7 million. The increase in operation and maintenance expenses was primarily due to increased outside service costs of $26.2 million, higher regulatory trackers, which are offset in net revenues, of $24.7 million and increased employee and administrative costs of $20.4 million. The increase in depreciation and amortization is primarily due to higher capital expenditures placed in service. The decrease in the gain on the sale of assets primarily resulted from lower gains on conveyance of mineral interests of $12.2 million.
Equity Earnings in Unconsolidated Affiliates
Equity Earnings in Unconsolidated Affiliates were $15.4 million during the first quarter of 2015 compared to $9.8 million for the first quarter of 2014. Equity Earnings in Unconsolidated Affiliates includes earnings from investments in Millennium, Hardy Storage and Pennant, which are integral to the Columbia Pipeline Group Operations’ business. Equity earnings increased primarily from increased earnings at Millennium attributable to growth projects placed in service and higher earnings at Pennant as a result of the joint venture projects going fully in-service.
Other Income (Deductions)
Other Income (Deductions) reduced income by $103.9 million in the first quarter of 2015 compared to a reduction in income of $104.6 million in the prior year.
Income Taxes
Income tax expense for the quarter ended March 31, 2015 was $150.9 million compared to $162.7 million in the prior year. NiSource’s interim effective tax rates reflect the estimated annual effective tax rates for 2015 and 2014, adjusted for tax expense associated with certain discrete items. The effective tax rates for the quarters ended March 31, 2015 and 2014 were 35.4% and 37.9%, respectively. These effective tax rates differ from the Federal tax rate of 35% primarily due to the effects of tax credits, state income taxes, utility ratemaking, and other permanent book-to-tax differences. The decrease in the three month effective tax rate of 2.5% in 2015 versus 2014 is primarily due to the impact of the Indiana rate change in 2014. Refer to Note 11, "Income Taxes," in the Notes to Condensed Consolidated Financial Statements (unaudited) for further discussion of income taxes.
Liquidity and Capital Resources
A significant portion of NiSource’s operations, most notably in the gas distribution, gas transportation and electric businesses, are subject to seasonal fluctuations in cash flow. During the heating season, which is primarily from November through March, cash receipts from gas sales and transportation services typically exceed cash requirements. During the summer months, cash on hand, together with the seasonal increase in cash flows from the electric business during the summer cooling season and external short-term and long-term financing, is used to purchase gas to place in storage for heating season deliveries and perform necessary maintenance of facilities. NiSource believes that through income generated from operating activities, amounts available under its short-term revolver, commercial paper program, long-term debt agreements and NiSource’s ability to access the capital markets, there is adequate capital available to fund its operating activities and capital expenditures in 2015.
Operating Activities
Net cash from operating activities for the three months ended March 31, 2015 was $604.3 million, an increase of $210.3 million compared to the three months ended March 31, 2014. The increase in net cash from operating activities was primarily due to an increase in overrecovered gas and fuel costs and accounts receivable working capital accounts as a result of lower gas prices and warmer weather in the first quarter of 2015 compared to the same period in 2014.
Pension and Other Postretirement Plan Funding.    NiSource expects to make contributions of approximately $3.5 million to its pension plans and approximately $34.8 million to its other postretirement benefit plans in 2015, which could change depending on market conditions. For the three months ended March 31, 2015, NiSource has contributed $0.7 million to its pension plans and $8.7 million to its other postretirement benefit plans.

NiSource Inc.


Investing Activities
NiSource’s capital expenditures for the three months ended March 31, 2015 were $407.5 million, compared to $386.3 million for the comparable period in 2014. This increased spending is mainly due to higher spending in the Columbia Pipeline Group Operations segment on various growth projects primarily in the Marcellus and Utica Shale areas and for expenditures under the modernization program. NiSource projects 2015 capital expenditures to be approximately $2.4 billion.
Restricted cash was $21.6 million and $24.9 million as of March 31, 2015 and December 31, 2014, respectively.
Contributions to equity investees decreased $32.2 million primarily due to no contributions being made to Pennant during the first quarter of 2015 as a result of the joint venture projects going fully in-service.

Financing Activities
Columbia Pipeline Partners LP. CPPL received net proceeds of $1,168.4 million from its IPO completed on February 11, 2015.

Credit Facilities.     NiSource Finance currently maintains a $2.0 billion revolving credit facility with a syndicate of banks led by Barclays Capital with a termination date of September 28, 2018. The purpose of the facility is to fund ongoing working capital requirements including the provision of liquidity support for NiSource’s $1.5 billion commercial paper program, provide for issuance of letters of credit, and also for general corporate purposes. In December 2014, with an effective date pending the Proposed Separation of NiSource and CPG, NiSource Finance revised the $2.0 billion revolver to $1.5 billion and extended the termination date to the fifth anniversary of the effective date. Contemporaneous with the revision to NiSource Finance’s revolving credit facility, revolving credit facilities were established for CPG and CPPL in the amount of $1.5 billion and $500 million, respectively.
As of March 31, 2015, NiSource has deferred $8.8 million of debt issuance costs related to the establishment of the CPG and CPPL credit facilities and the revision of the NiSource Finance facility.

The $1.5 billion CPG credit facility will be effective with the Proposed Separation.

CPPL's $500 million revolving credit facility, of which $50 million will be available for issuance of letters of credit, became effective upon the closing of the IPO. The purpose of the facility is to provide cash for general partnership purposes, including working capital, capital expenditures and the funding of capital calls.

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, RBS and Wells Fargo. Commercial paper issuances are supported by available capacity under NiSource’s $2.0 billion unsecured revolving credit facility, which expires in September 2018. The aforementioned pending revolver amendment for NiSource Finance and pending revolver for CPG are expected to support commercial paper borrowings of $1.5 billion each. CPPL is not expected to issue commercial paper.

NiSource Finance had no borrowings outstanding under its revolving credit facility at March 31, 2015 and $500.0 million at December 31, 2014 at a weighted average interest rate of 1.44%. In addition, NiSource Finance had $39.0 million in commercial paper outstanding at March 31, 2015, at a weighted average interest rate of 0.96% and $792.6 million in commercial paper outstanding at December 31, 2014, at a weighted average interest rate of 0.82%.
As of March 31, 2015 and December 31, 2014, NiSource had $275.0 million and $284.3 million, respectively, of short-term borrowings recorded on the Condensed Consolidated Balance Sheets (unaudited) relating to its accounts receivable securitization facilities. See Note 9, “Transfers of Financial Assets,” in the Notes to Condensed Consolidated Financial Statements (unaudited).
As of March 31, 2015 and December 31, 2014, NiSource had $30.9 million of stand-by letters of credit outstanding of which $14.7 million were under the revolving credit facility.
As of March 31, 2015, an aggregate of $1,946.3 million of credit was available under the credit facility.
Debt Covenants. NiSource is subject to a financial covenant under its revolving credit facility and its three-year term loans, which require 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 March 31, 2015, the ratio was 53.9%.
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, lease and/or transfer of NiSource’s assets to no more than 10% of its consolidated total assets and dispositions for a price not materially less than the fair market value of the assets disposed of that do not impair the ability of NiSource and 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 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 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.
CPPL's revolving credit facility contains various covenants and restrictive provisions which, among other things, limit CPPL’s and its restricted subsidiaries’ ability to incur additional indebtedness, guarantees and/or liens; consolidate, merge or transfer all or substantially all of their assets; make certain investments or restricted payments; modify certain material agreements; engage in certain types of transactions with affiliates; dispose of assets; and prepay certain indebtedness, each of which is subject to customary and usual exceptions and baskets, including an exception to the limitation on restricted payments for distributions of available cash, as permitted by CPPL's organizational documents. If CPPL fails to perform its obligations under these and other covenants, the revolving credit commitment could be terminated and any outstanding borrowings, together with accrued interest, under the revolving credit facility could be declared immediately due and payable. The CPPL revolving credit facility also contains customary events of default, including cross default provisions that apply to any other indebtedness CPPL may have with an outstanding principal amount in excess of $50 million.
CPPL's revolving credit facility also contains certain negative financial covenants that will require CPPL (a) to maintain a consolidated total leverage ratio that does not exceed (i) 5.75 to 1.00 for the test period ending December 31, 2015, (ii) 5.50 to 1.00 for any test period ending after December 31, 2015 and on or before December 31, 2017, and (iii) 5.00 to 1.00 for any test period ending after December 31, 2017, provided that after December 31, 2017 and during a Specified Acquisition Period (as defined in CPPL's revolving credit facility), then the leverage ratio may not exceed 5.50 to 1.00 and (b) until CPG has received an investment grade rating, to maintain a Consolidated Interest Coverage Ratio (as defined in the MLP revolving credit facility) of no less than 3.00 to 1.00.
A breach by CPPL of any of these covenants could result in a default in respect of the related debt. If a default occurred, the relevant lenders could elect to declare the debt, together with accrued interest and other fees, to be immediately due and payable and proceed against CPPL or any guarantor, including NiSource.
Sale of Trade Accounts Receivables.    Refer to Note 9, “Transfers of Financial Assets,” in the Notes to Condensed Consolidated Financial Statements (unaudited) for information on the sale of trade accounts receivable.
All accounts receivable 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.

Credit Ratings.    On March 30, 2015, Standard & Poor's affirmed the senior unsecured ratings for NiSource and its subsidiaries at BBB- and the commercial paper rating of A-3. Standard & Poor's outlook for NiSource and all of its subsidiaries is Watch Positive. On September 29, 2014, Moody's affirmed the NiSource senior unsecured rating of Baa2 and commercial paper rating of P-2, with a stable outlook. Additionally, Moody's affirmed NIPSCO’s Baa1 rating and affirmed the Baa2 rating for Columbia of Massachusetts. On September 29, 2014, Fitch affirmed the senior unsecured ratings for NiSource at BBB-, and the existing ratings of its other rated subsidiaries. Fitch's outlook for NiSource and its subsidiaries is stable. Although all ratings continue to be investment grade, a downgrade by either Standard & Poor's or Fitch would result in a rating that is below investment grade.

Certain NiSource affiliates have agreements that contain “ratings triggers” that require increased collateral if the credit ratings of NiSource or certain of its subsidiaries are rated below BBB- by Standard & Poor's or Baa3 by Moody's. These agreements are primarily for insurance purposes and for the physical purchase or sale of power. The collateral requirement that would be required in the event of a downgrade below the ratings trigger levels would amount to approximately $39.7 million as of March 31, 2015. In addition to agreements with ratings triggers, there are other agreements that contain “adequate assurance” or “material adverse change” provisions that could necessitate additional credit support such as letters of credit and cash collateral to transact business.

Contractual Obligations.    There were no material changes recorded during the three months ended March 31, 2015 to NiSource’s contractual obligations as of December 31, 2014.
Market Risk Disclosures
Risk is an inherent part of NiSource’s energy businesses. The extent to which NiSource properly and effectively identifies, assesses, monitors and manages each of the various types of risk involved in its businesses is critical to its profitability. NiSource seeks to identify, assess, monitor and manage, in accordance with defined policies and procedures, the following principal market risks that are involved in NiSource’s energy businesses: commodity price risk, interest rate risk and credit risk. Risk management at NiSource is a multi-faceted process with oversight by the Risk Management Committee that requires constant communication, judgment and knowledge of specialized products and markets. NiSource’s senior management takes an active role in the risk management process and has developed policies and procedures that require specific administrative and business functions to assist in the identification, assessment and control of various risks. These include but are not limited to market, operational, financial, compliance and strategic risk types. In recognition of the increasingly varied and complex nature of the energy business, NiSource’s risk management process, policies and procedures continue to evolve and are subject to ongoing review and modification.
Commodity Price Risk
NiSource is exposed to commodity price risk as a result of its subsidiaries’ operations involving natural gas and power. To manage this market risk, NiSource’s subsidiaries use derivatives, including commodity futures contracts, swaps and options. NiSource is not involved in speculative energy trading activity.
Commodity price risk resulting from derivative activities at NiSource’s rate-regulated subsidiaries is limited, since regulations allow recovery of prudently incurred purchased power, fuel and gas costs through the ratemaking process, including gains or losses on these derivative instruments. If states should explore additional regulatory reform, these subsidiaries may begin providing services without the benefit of the traditional ratemaking process and may be more exposed to commodity price risk. Some of NiSource’s rate-regulated utility subsidiaries offer commodity price risk products to its customers for which derivatives are used to hedge forecasted customer usage under such products. These subsidiaries do not have regulatory recovery orders for these products and are subject to gains and losses recognized in earnings due to hedge ineffectiveness.
There are no material commodity price risk assets or liabilities as of March 31, 2015 and December 31, 2014.
Interest Rate Risk
NiSource is exposed to interest rate risk as a result of changes in interest rates on borrowings under its revolving credit agreement, term loans, commercial paper program and accounts receivable programs, which have interest rates that are indexed to short-term market interest rates. Based upon average borrowings and debt obligations subject to fluctuations in short-term market interest rates, an increase (or decrease) in short-term interest rates of 100 basis points (1%) would have increased (or decreased) interest expense by $4.9 million for the three months ended March 31, 2015 and $3.7 million for the three months ended March 31, 2014.

Credit Risk
Due to the nature of the industry, credit risk is embedded in many of NiSource’s business activities. NiSource’s extension of credit is governed by a Corporate Credit Risk Policy. In addition, Risk Management Committee guidelines are in place which document management approval levels for credit limits, evaluation of creditworthiness, and credit risk mitigation efforts. Exposures to credit risks are monitored by the Corporate Credit Risk function which is independent of commercial operations. Credit risk arises due to the possibility that a customer, supplier or counterparty will not be able or willing to fulfill its obligations on a transaction on or before the settlement date. For derivative related contracts, credit risk arises when counterparties are obligated to deliver or purchase defined commodity units of gas or power to NiSource at a future date per execution of contractual terms and conditions. Exposure to credit risk is measured in terms of both current obligations and the market value of forward positions net of any posted collateral such as cash and letters of credit.
NiSource closely monitors the financial status of its banking credit providers. NiSource evaluates the financial status of its banking partners through the use of market-based metrics such as credit default swap pricing levels, and also through traditional credit ratings provided by major credit rating agencies.

Fair Value Measurement
NiSource measures certain financial assets and liabilities at fair value. The level of the fair value hierarchy disclosed is based on the lowest level of input that is significant to the fair value measurement. NiSource’s financial assets and liabilities include price risk assets and liabilities, available-for-sale securities and a deferred compensation plan obligation.
Exchange-traded derivative contracts are generally 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, NiSource may utilize models to measure fair value. 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 in 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 in 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.
Refer to Note 8, “Fair Value” in the Notes to the Condensed Consolidated Financial Statements (unaudited) for additional information on NiSource’s fair value measurements.
Off Balance Sheet Arrangements
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.

NiSource has purchase and sales agreement guarantees totaling $25.6 million, which guarantee purchaser performance or seller performance under covenants, obligations, liabilities, representations or warranties under the agreements. No amounts related to the purchase and sales agreement guarantees are reflected in the Condensed Consolidated Balance Sheets (unaudited). Management believes that the likelihood NiSource would be required to perform or otherwise incur any significant losses associated with any of the aforementioned guarantees is remote.

NiSource has other guarantees outstanding. Refer to Note 16-A, “Other Commitments and Guarantees - Guarantees and Indemnities,” in the Notes to Condensed Consolidated Financial Statements (unaudited) for additional information about NiSource’s off balance sheet arrangements.
