Significant Accounting Policies [Text Block] | ' | ||||||||
Nature of Operations and Summary of Significant Accounting Policies | |||||||||
A. Company Structure and Principles of Consolidation. NiSource, a Delaware corporation, is a holding company whose subsidiaries provide natural gas, electricity and other products and services to approximately 3.8 million customers located within a corridor that runs from the Gulf Coast through the Midwest to New England. NiSource derives substantially all of its revenues and earnings from the operating results of its thirteen direct subsidiaries. | |||||||||
The consolidated financial statements include the accounts of NiSource and its majority-owned subsidiaries after the elimination of all intercompany accounts and transactions. Investments for which at least a 20% interest is owned, certain joint ventures and limited partnership interests of more than 3% are accounted for under the equity method. Except where noted above and in the event where NiSource has significant influence, investments with less than a 20% interest are accounted for under the cost method. NiSource also consolidates variable interest entities for which NiSource is the primary beneficiary. | |||||||||
B. Use of Estimates. The preparation of financial statements in conformity with GAAP in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. | |||||||||
C. Cash, Cash Equivalents, and Restricted Cash. NiSource considers all investments with original maturities of three months or less to be cash equivalents. NiSource reports amounts deposited in brokerage accounts for margin requirements as restricted cash. In addition, NiSource has amounts deposited in trust to satisfy requirements for the provision of various property, liability, workers compensation, and long-term disability insurance, which is classified as restricted cash and disclosed as an investing cash flow on the Statements of Consolidated Cash Flows. | |||||||||
Restricted cash was $8.0 million and $46.8 million as of December 31, 2013, and 2012, respectively. The decrease in restricted cash was primarily a result of the sale of NiSource’s unregulated natural gas marketing business. | |||||||||
D. Accounts Receivable and Unbilled Revenue. Accounts receivable on the Consolidated Balance Sheets includes both billed and unbilled amounts as NiSource believes that total accounts receivable is a more meaningful presentation, given the factors which impact both billed and unbilled accounts receivable. Unbilled revenue is based on estimated amounts of electric energy or natural gas delivered but not yet billed to its customers. Unbilled amounts of accounts receivable relate to a portion of a customer’s consumption of gas or electricity from the date of the last cycle billing date through the last day of the month (balance sheet date). Factors taken into consideration when estimating unbilled revenue include historical usage, customer rates and weather. Accounts receivable fluctuates from year to year depending in large part on weather impacts and price volatility. NiSource’s accounts receivable on the Consolidated Balance Sheets includes unbilled revenue, less reserves, in the amounts of $321.5 million and $285.7 million for the years ended December 31, 2013 and 2012, respectively. The reserve for uncollectible receivables is the Company’s best estimate of the amount of probable credit losses in the existing accounts receivable. The Company determined the reserve based on historical experience and in consideration of current market conditions. Account balances are charged against the allowance when it is anticipated the receivable will not be recovered. | |||||||||
E. Investments in Debt and Equity Securities. NiSource’s investments in debt and equity securities are carried at fair value and are designated as available-for-sale. These investments are included within “Other investments” on the Consolidated Balance Sheets. Unrealized gains and losses, net of deferred income taxes, are reflected as accumulated other comprehensive income (loss). These investments are monitored for other than temporary declines in market value. Realized gains and losses and permanent impairments are reflected in the Statements of Consolidated Income. No material impairment charges were recorded for the years ended December 31, 2013, 2012 and 2011. | |||||||||
F. Basis of Accounting for Rate-Regulated Subsidiaries. Rate-regulated subsidiaries account for and report assets and liabilities consistent with the economic effect of the way in which regulators establish rates, if the rates established are designed to recover the costs of providing the regulated service and it is probable that such rates can be charged and collected. Certain expenses and credits subject to utility regulation or rate determination normally reflected in income are deferred on the Consolidated Balance Sheets and are recognized in income as the related amounts are included in service rates and recovered from or refunded to customers. | |||||||||
In the event that regulation significantly changes the opportunity for NiSource to recover its costs in the future, all or a portion of NiSource’s regulated operations may no longer meet the criteria for regulatory accounting. In such an event, a write-down of all or a portion of NiSource’s existing regulatory assets and liabilities could result. If transition cost recovery was approved by the appropriate regulatory bodies that would meet the requirements under generally accepted accounting principles for continued accounting as regulatory assets and liabilities during such recovery period, the regulatory assets and liabilities would be reported at the recoverable amounts. If unable to continue to apply the provisions of regulatory accounting, NiSource would be required to apply the provisions of Discontinuation of Rate-Regulated Accounting. In management’s opinion, NiSource’s regulated subsidiaries will be subject to regulatory accounting for the foreseeable future. Refer to Note 8, “Regulatory Matters,” in the Notes to Consolidated Financial Statements for additional information. | |||||||||
G. Utility Plant and Other Property and Related Depreciation and Maintenance. Property, plant and equipment (principally utility plant) is stated at cost. The rate-regulated subsidiaries record depreciation using composite rates on a straight-line basis over the remaining service lives of the electric, gas and common properties as approved by the appropriate regulators. | |||||||||
The weighted average depreciation provisions for utility plant, as a percentage of the original cost, for the periods ended December 31, 2013, 2012 and 2011 were as follows: | |||||||||
2013 | 2012 | 2011 | |||||||
Electric Operations | 3.2 | % | 3.4 | % | 3.5 | % | |||
Gas Distribution and Transmission Operations | 1.8 | % | 1.9 | % | 2.1 | % | |||
For rate-regulated companies, AFUDC is capitalized on all classes of property except organization costs, land, autos, office equipment, tools and other general property purchases. The allowance is applied to construction costs for that period of time between the date of the expenditure and the date on which such project is placed in service. The pre-tax rate for AFUDC was 2.4% in 2013, 3.3% in 2012 and 3.6% in 2011. Short-term borrowings were primarily used to fund construction efforts for all three years presented. | |||||||||
Generally, NiSource’s subsidiaries follow the practice of charging maintenance and repairs, including the cost of removal of minor items of property, to expense as incurred. When regulated property that represents a retired unit is replaced or removed, the cost of such property is credited to utility plant, and such cost, net of salvage, is charged to the accumulated provision for depreciation in accordance with composite depreciation. | |||||||||
In the third quarter of 2013, Columbia Transmission sold storage base gas. The difference between the sale proceeds and amounts capitalized to Utility Plant resulted in a gain of $11.1 million. | |||||||||
H. Carrying Charges and Deferred Depreciation. Upon completion of units 17 and 18 at the R. M. Schahfer Generating Station, NIPSCO capitalized the debt-based carrying charges and deferred depreciation in accordance with orders of the IURC, pending the inclusion of the cost of each unit in rates. Such carrying charges and deferred depreciation are being amortized over the remaining service life of each unit. | |||||||||
NIPSCO has capitalized debt-based carrying charges and deferred depreciation related to Sugar Creek in accordance with the February 18, 2008 Order of the IURC. The deferral of Sugar Creek debt based carrying charges and the deferral of depreciation ceased in December 2011 and deferred balances are being amortized over five years beginning January 2012. As of December 31, 2013, the remaining balance to be amortized is $42.9 million. An additional $13.9 million is deferred for consideration in NIPSCO's next electric base rate case. Management believes this amount is probable of recovery through future rates. | |||||||||
In 2005, the PUCO authorized Columbia of Ohio to revise its depreciation accrual rates for the period beginning January 1, 2005. The revised depreciation rates are now higher than those which would have been utilized if Columbia of Ohio were not subject to regulation. The amount of depreciation that would have been recorded for 2005 through 2013 had Columbia of Ohio not been subject to rate regulation is a combined $414.2 million, a $53.0 million decrease over the $467.2 million reflected in rates. The regulatory asset was $78.7 million and $84.8 million as of December 31, 2013 and 2012, respectively. The amount of depreciation that would have been recorded for 2013 had Columbia of Ohio not been subject to rate regulation is $66.3 million, a $6.0 million decrease over the $72.3 million reflected in rates. | |||||||||
I. Amortization of Software Costs. External and internal costs associated with computer software developed for internal use are capitalized. Capitalization of such costs commences upon the completion of the preliminary stage of each project. Once the installed software is ready for its intended use, such capitalized costs are amortized on a straight-line basis generally over a period of five years. NiSource amortized $36.3 million in 2013, $30.6 million in 2012 and $29.0 million in 2011 related to software costs. NiSource’s unamortized software balance was $149.1 million and $142.6 million at 2013 and 2012, respectively. | |||||||||
J. Goodwill and Other Intangible Assets. NiSource has approximately $4 billion in goodwill and other intangible assets. Substantially all goodwill relates to the excess of cost over the fair value of the net assets acquired in the Columbia acquisition. In addition, NiSource has other intangible assets consisting primarily of franchise rights apart from goodwill that were identified as part of the purchase price allocations associated with the acquisition of Columbia of Massachusetts, a wholly-owned subsidiary of NiSource, which is being amortized on a straight-line basis over forty years from the date of acquisition. Refer to Note 6, “Goodwill and Other Intangible Assets,” in the Notes to Consolidated Financial Statements for additional information. | |||||||||
K. Long-lived Assets. NiSource’s Consolidated Balance Sheets contain significant long-lived assets other than goodwill and intangible assets discussed above which are not subject to recovery under regulatory accounting. As a result, NiSource assesses the carrying amount and potential earnings of these assets whenever events or changes in circumstances indicate that the carrying value could be impaired. Refer to Note 3, “Impairments and Other Charges,” in the Notes to Consolidated Financial Statements for further information. | |||||||||
L. Revenue Recognition. Revenue is recorded as products and services are delivered. Utility revenues are billed to customers monthly on a cycle basis. Revenues are recorded on the accrual basis and include estimates for electricity and gas delivered but not billed. Cash received in advance from sales of commodities to be delivered in the future is recorded as deferred revenue and recognized as income upon delivery of the commodities. For shorter term transportation and storage service revenues, cash is received at inception of the service period resulting in the recording of deferred revenues that are recognized in revenues over the period the services are provided. | |||||||||
Deferred revenue also includes a gain on conveyances related to pooling of assets (production rights) in a joint undertaking intended to find, develop, or produce oil or gas from a particular property or group of properties. NiSource has a working and an overriding royalty interest in the assets. The gain was initially deferred as NiSource has a substantial obligation for future performance. NiSource recognizes the gain on conveyances into earnings as the obligation is satisfied ($7.3 million in 2013). As of December 31, 2013, remaining gains of approximately $30.0 million were deferred pending performance of future obligations. | |||||||||
M. Earnings Per Share. Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The weighted average shares outstanding for diluted EPS include the incremental effects of the various long-term incentive compensation plans and the Forward Agreements (see Note 14). The calculation of diluted earnings per share excludes stock options which had an anti-dilutive effect. These options were zero for 2013 and 2012 and 2.8 million for 2011. | |||||||||
The numerator in calculating both basic and diluted EPS for each year is reported net income. The computation of diluted average common shares follows: | |||||||||
Diluted Average Common Shares Computation | 2013 | 2012 | 2011 | ||||||
Denominator (thousands) | |||||||||
Basic average common shares outstanding | 312,402 | 291,927 | 280,442 | ||||||
Dilutive potential common shares | |||||||||
Nonqualified stock options | 80 | 144 | 9 | ||||||
Shares contingently issuable under employee stock plans | 708 | 557 | 1,017 | ||||||
Shares restricted under stock plans | 456 | 544 | 339 | ||||||
Forward Agreements(1) | — | 7,229 | 6,684 | ||||||
Diluted Average Common Shares | 313,646 | 300,401 | 288,491 | ||||||
(1) On September 10, 2012, NiSource settled the Forward Agreements. Amounts included in diluted average common shares for the year ended December 31, 2012 are weighted for the period prior to settlement. | |||||||||
N. Estimated Rate Refunds. Certain rate-regulated subsidiaries collect revenues subject to refund pending final determination in rate proceedings. In connection with such revenues, estimated rate refund liabilities are recorded which reflect management’s current judgment of the ultimate outcomes of the proceedings. No provisions are made when, in the opinion of management, the facts and circumstances preclude a reasonable estimate of the outcome. | |||||||||
O. Accounts Receivable Transfer Program. Certain of NiSource’s subsidiaries have agreements with third parties to sell certain accounts receivable without recourse. These transfers of accounts receivable are accounted for as secured borrowings. The entire gross receivables balance remains on the December 31, 2013 and 2012 Consolidated Balance Sheets and short-term debt is recorded in the amount of proceeds received from the commercial paper conduits involved in the transactions. Fees associated with the securitization transactions are recorded as interest expense. Refer to Note 19, “Transfers of Financial Assets,” in the Notes to Consolidated Financial Statements for further information. | |||||||||
P. Fuel Adjustment Clause. NIPSCO defers most differences between fuel and power purchase costs and the recovery of such costs in revenue, and adjusts future billings for such deferrals on a basis consistent with applicable state-approved tariff provisions. | |||||||||
Q. Gas Cost Adjustment Clause. All of NiSource’s Gas Distribution Operations subsidiaries defer most differences between gas purchase costs and the recovery of such costs in revenues, and adjust future billings for such deferrals on a basis consistent with applicable state-approved tariff provisions. | |||||||||
R. Gas Inventory. Both the LIFO inventory methodology and the weighted average cost methodology are used to value natural gas in storage, as approved by regulators for each of NiSource’s regulated subsidiaries. Inventory valued using LIFO was $45.5 million and $48.4 million at December 31, 2013, and 2012, respectively. Based on the average cost of gas using the LIFO method, the estimated replacement cost of gas in storage was greater than the stated LIFO cost by $0.6 million at December 31, 2013 and was less than the stated LIFO cost by $13.2 million at December 31, 2012. Inventory valued using the weighted average cost methodology was $309.1 million at December 31, 2013 and $278.2 million at December 31, 2012. | |||||||||
S. Accounting for Exchange and Balancing Arrangements of Natural Gas. NiSource’s Columbia Pipeline Group and Gas Distribution Operations subsidiaries enter into balancing and exchange arrangements of natural gas as part of their operations and off-system sales programs. NiSource records a receivable or payable for its respective cumulative gas imbalances as well as for any gas inventory borrowed or lent under a Gas Distributions Operations exchange agreement. These receivables and payables are recorded as “Exchange gas receivable” or “Exchange gas payable” on NiSource’s Consolidated Balance Sheets, as appropriate. | |||||||||
T. Accounting for Emissions Allowances. NIPSCO has obtained SO2 and NOx emissions allowances from the EPA based upon its electric generation operations that the utility may sell, trade or hold for future use. NIPSCO utilizes the inventory model in accounting for these emissions allowances, whereby these allowances were recognized at zero cost upon receipt from the EPA. Pursuant to the December 21, 2011 IURC Order, all purchases and sales of emission allowances will be recovered or refunded through the EERM. | |||||||||
U. Accounting for Risk Management Activities. NiSource accounts for its derivatives and hedging activities in accordance with ASC 815. NiSource recognizes all derivatives as either assets or liabilities on the Consolidated Balance Sheets at fair value, unless such contracts are exempted as a normal purchase normal sale under the provisions of the standard. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and resulting designation. Refer to Note 9, “Risk Management Activities,” in the Notes to Consolidated Financial Statements for additional information. | |||||||||
V. Income Taxes and Investment Tax Credits. NiSource records income taxes to recognize full interperiod tax allocations. Under the liability method, deferred income taxes are provided for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. Previously recorded investment tax credits of the regulated subsidiaries were deferred on the balance sheet and are being amortized to book income over the regulatory life of the related properties to conform to regulatory policy. | |||||||||
To the extent certain deferred income taxes of the regulated companies are recoverable or payable through future rates, regulatory assets and liabilities have been established. Regulatory assets for income taxes are primarily attributable to property related tax timing differences for which deferred taxes had not been provided in the past, when regulators did not recognize such taxes as costs in the rate-making process. Regulatory liabilities for income taxes are primarily attributable to the regulated companies’ obligation to refund to ratepayers deferred income taxes provided at rates higher than the current federal income tax rate. Such amounts are credited to ratepayers using either the average rate assumption method or the reverse South Georgia method. | |||||||||
Pursuant to the Internal Revenue Code and relevant state taxing authorities, NiSource and its subsidiaries file consolidated income tax returns for federal and certain state jurisdictions. NiSource and its subsidiaries are parties to an agreement (Tax Allocation Agreement) that provides for the allocation of consolidated tax liabilities. The Tax Allocation Agreement generally provides that each party is allocated an amount of tax similar to that which would be owed had the party been separately subject to tax. Any net benefit attributable to the parent is reallocated to other members. | |||||||||
W. Environmental Expenditures. NiSource accrues for costs associated with environmental remediation obligations when the incurrence of such costs is probable and the amounts can be reasonably estimated, regardless of when the expenditures are actually made. The undiscounted estimated future expenditures are based on currently enacted laws and regulations, existing technology and estimated site-specific costs where assumptions may be made about the nature and extent of site contamination, the extent of cleanup efforts, costs of alternative cleanup methods and other variables. The liability is adjusted as further information is discovered or circumstances change. The reserves for estimated environmental expenditures are recorded on the Consolidated Balance Sheets in “Legal and environmental reserves” for short-term portions of these liabilities and “Other noncurrent liabilities” for the respective long-term portions of these liabilities. Rate-regulated subsidiaries applying regulatory accounting establish regulatory assets on the Consolidated Balance Sheets to the extent that future recovery of environmental remediation costs is probable through the regulatory process. Refer to Note 20, “Other Commitments and Contingencies,” in the Notes to Consolidated Financial Statements for further information. | |||||||||
X. Excise Taxes. NiSource accounts for excise taxes that are customer liabilities by separately stating on its invoices the tax to its customers and recording amounts invoiced as liabilities payable to the applicable taxing jurisdiction. These types of taxes, comprised largely of sales taxes collected, are presented on a net basis affecting neither revenues nor cost of sales. NiSource accounts for other taxes for which it is liable by recording a liability for the expected tax with a corresponding charge to “Other taxes” expense. |

Impairments. An impairment loss shall be recognized only if the carrying amount of a long lived asset is not recoverable and exceeds its fair value. The first step of the test for impairment compares the carrying amount of the long lived asset to the fair value sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. | |
Lake Erie Land, which is wholly-owned by NiSource and within the Company’s Corporate and Other Segment, was in the process of selling real estate over a 10-year period as a part of an agreement reached in June 2006 with a private real estate development group. | |
In April 2011, NiSource settled a mortgage foreclosure action against the developer, reacquired the Sand Creek Country Club, and purchased additional properties owned by the developer to be marketed along with the existing Lake Erie Land properties to prospective purchasers. This transaction qualified as a business combination in accordance with GAAP. The properties were acquired at fair value and included the Sand Creek Country Club and additional commercial properties for a total of $15.8 million as well as $3.5 million of land. As a result of these acquisitions, NiSource’s total investment in Lake Erie Land was $51.3 million. As a part of the process to sell the Lake Erie Land properties in 2011, independent appraisals were obtained. The Company compared the carrying value of the assets to the fair value, determined primarily through the independent appraisals, and recorded an impairment loss of $14.7 million. The Company has analyzed the properties for indicators of impairment and determined there were no impairment charges during 2013 and 2012. At December 31, 2013 and December 31, 2012, the total book value of these properties was $31.4 million and $35.4 million, respectively, and is included in Other investments and Other property in the Consolidated Balance Sheets. NiSource is marketing the Lake Erie Land properties, but has determined that the sale would not be probable within a year and, therefore, the properties did not meet the criteria to be classified as assets held for sale in accordance with GAAP as of December 31, 2013, and December 31, 2012. The revenue and earnings of Sand Creek Country Club are not material. |

On September 1, 2013, NiSource sold the commercial and industrial natural gas portfolio of its unregulated natural gas marketing business. The sale included the physical contracts and associated financial hedges that comprise the portfolio, as well as the gas inventory and customer deposits of the business. For the year ended December 31, 2013, an after tax loss of $1.5 million was included in Gain on Disposition of Discontinued Operations, net of taxes in the Statements of Consolidated Income. The assets and liabilities sold were classified as held for sale as of December 31, 2012. Refer to Note 9, "Risk Management Activities" for additional information regarding the price risk assets and liabilities of the business. | |||||||||||||
During 2012, NiSource began marketing to sell the service plan and leasing business lines of its Retail Services business. As of December 31, 2012, the assets and liabilities of the business lines met the criteria to be classified as held for sale in accordance with GAAP. Additionally, the results of operations and cash flows are classified as discontinued operations for all periods presented. The sale of the business lines closed in January 2013 resulting in gain from the disposal of discontinued operations of $36.4 million after taxes, which was recorded during the first quarter of 2013. | |||||||||||||
There were no assets and liabilities of discontinued operations and held for sale on the Consolidated Balance Sheet at December 31, 2013. | |||||||||||||

Goodwill and Other Intangible Assets | |
In accordance with the provisions for goodwill accounting under GAAP, NiSource tests its goodwill for impairment annually as of May 1 each year unless indicators, events, or circumstances would require an immediate review. Goodwill is tested for impairment at a level of reporting referred to as a reporting unit, which generally is an operating segment or a component of an operating segment as defined by the FASB. NiSource's three reporting units are Columbia Distribution Operations, Columbia Transmission Operations and NIPSCO Gas Distribution Operations. | |
NiSource has three reporting units that are allocated goodwill. NiSource’s goodwill assets at December 31, 2013 were $3.7 billion pertaining primarily to the acquisition of Columbia on November 1, 2000. Of this amount, approximately $2.0 billion is allocated to Columbia Transmission Operations and $1.7 billion is allocated to Columbia Distribution Operations. In addition, NIPSCO Gas Distribution Operations’ goodwill assets at December 31, 2013 related to the purchase of Northern Indiana Fuel and Light in March 1993 and Kokomo Gas in February 1992 were $17.8 million. | |
NiSource completed a quantitative ("step 1") fair value measurement of its reporting units during the May 1, 2012 goodwill test. The test indicated that the fair value of each of the reporting units that carry or are allocated goodwill substantially exceeded their carrying values, indicating that no impairment existed under the step 1 annual impairment test. | |
In estimating the fair value of the Columbia Transmission Operations and Columbia Distribution Operations reporting units for the May 1, 2012 test, NiSource used a weighted average of the income and market approaches. The income approach utilized a discounted cash flow model. This model was based on management’s short-term and long-term forecast of operating performance for each reporting unit. The two main assumptions used in the models were the growth rates, which were based on the cash flows from operations for each of the reporting units, and the weighted average cost of capital, or discount rate. The starting point for each reporting unit’s cash flow from operations was the detailed five year plan, which takes into consideration a variety of factors such as the current economic environment, industry trends, and specific operating goals set by management. The discount rates were based on trends in overall market as well as industry specific variables and include components such as the risk-free rate, cost of debt, and company volatility at May 1, 2012. Under the market approach, NiSource utilized three market-based models to estimate the fair value of the reporting units: (i) the comparable company multiples method, which estimated fair value of each reporting unit by analyzing EBITDA multiples of a peer group of publicly traded companies and applying that multiple to the reporting unit’s EBITDA, (ii) the comparable transactions method, which valued the reporting unit based on observed EBITDA multiples from completed transactions of peer companies and applying that multiple to the reporting unit’s EBITDA, and (iii) the market capitalization method, which used the NiSource share price and allocated NiSource’s total market capitalization among both the goodwill and non-goodwill reporting units based on the relative EBITDA, revenues, and operating income of each reporting unit. Each of the three market approaches were calculated with the assistance of a third party valuation firm, using multiples and assumptions inherent in today’s market. The degree of judgment involved and reliability of inputs into each model were considered in weighting the various approaches. The resulting estimate of fair value of the reporting units, using the weighted average of the income and market approaches, exceeded their carrying values, indicating that no impairment exists under step 1 of the annual impairment test. | |
Certain key assumptions used in determining the fair values of the reporting units included planned operating results, discount rates and the long-term outlook for growth. In 2012, NiSource used discount rates of 5.60% for both Columbia Transmission Operations and Columbia Distribution Operations, resulting in excess fair values of approximately $1,643.0 million and $1,682.0 million, respectively. The results of the impairment test indicated that each of the reporting units passed step 1 of the impairment test. | |
Goodwill at NIPSCO Gas Distribution Operations related to the acquisition of Northern Indiana Fuel and Light and Kokomo Gas of $17.8 million was also tested for impairment as of May 1, 2012. The income approach was used to determine the fair value of the NIPSCO Gas Distribution reporting unit. Key assumptions in the income approach were a discount rate of 5.60% and a growth rate based on the cash flow from operations. These cash flows factor in the regulatory environment and planned growth initiatives. The step 1 goodwill impairment test resulted in the fair value of the NIPSCO Gas Distribution reporting unit to be above the carrying value by $356.0 million. | |
In September 2011, FASB issued Accounting Standards Update 2011-08, which allows entities testing goodwill for impairment the option of performing a qualitative ("step 0") assessment before calculating the fair value of a reporting unit for the goodwill impairment test. If a step 0 assessment is performed, an entity is no longer required to calculate the fair value of a reporting unit unless the entity determines that based on the qualitative step 0 assessment that it is more likely than not that its fair value is less than its carrying amount. The update was effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. | |
NiSource applied this guidance for its 2013 annual test and applied the qualitative step 0 analysis to its reporting units for the annual impairment test performed as of May 1, 2013. | |
For the current year qualitative step 0 test performed as of May 1, 2013, NiSource assessed various assumptions, events and circumstances that would have affected the estimated fair value of the reporting units in its baseline May 1, 2012 test. 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 and no impairments are necessary. | |
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 subsequent to May 1, 2013. | |
During the first quarter of 2013, as part of the sale of the service plan and leasing business lines of its Retail Services business, NiSource allocated $10.0 million of goodwill from Columbia Distribution Operations to the sale and allocated $1.0 million of goodwill from NIPSCO Gas Distribution Operations to the sale. Refer to Note 4, "Discontinued Operations and Assets and Liabilities Held for Sale" for more information. | |
NiSource’s intangible assets, apart from goodwill, consist of franchise rights, which were identified as part of the purchase price allocations associated with the acquisition in February 1999 of Columbia of Massachusetts. These amounts were $275.7 million and $286.6 million, net of accumulated amortization of $166.5 million and $155.5 million, at December 31, 2013, and 2012, respectively and are being amortized over forty years from the date of acquisition. NiSource recorded amortization expense of $11.0 million in 2013, 2012, and 2011 related to its intangible assets. NiSource expects amortization expense to be $11.0 million a year from 2014-2018. |

NiSource has recognized asset retirement obligations associated with various legal obligations including costs to remove and dispose of certain construction materials located within many of NiSource’s facilities, certain costs to retire pipeline, removal costs for certain underground storage tanks, removal of certain pipelines known to contain PCB contamination, closure costs for certain sites including ash ponds, solid waste management units and a landfill, as well as some other nominal asset retirement obligations. NiSource recognizes that there are obligations to incur significant costs to retire wells associated with gas storage operations; however, the lives of these wells are indeterminable until management establishes plans for closure. Additionally, NiSource has a significant obligation associated with the decommissioning of its two hydro facilities located in Indiana. These hydro facilities have an indeterminate life, and no asset retirement obligation has been recorded. | ||||||||
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 and other removal costs on the Consolidated Balance Sheets. |

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

Regulatory assets, including underrecovered gas and fuel cost, of approximately $985.9 million as of December 31, 2013 are not earning a return on investment. Regulatory assets of approximately $1,560.7 million include expenses that are recovered as components of the cost of service and are covered by regulatory orders. These costs are recovered over a remaining life of up to 41 years. Regulatory assets of approximately $150.7 million at December 31, 2013, require specific rate action. | ||||||||
As noted below, regulatory assets for which costs have been incurred or accrued are included (or expected to be included, for costs incurred subsequent to the most recently approved rate case) in certain companies’ rate base, thereby providing a return on invested costs. Certain regulatory assets do not result from cash expenditures and therefore do not represent investments included in rate base or have offsetting liabilities that reduce rate base. | ||||||||
Assets: | ||||||||
Reacquisition premium on debt – The unamortized premiums for debt redeemed by NIPSCO are deferred, amortized and recovered over the term of the replacement issue. | ||||||||
R.M. Schahfer Unit 17 and Unit 18 carrying charges and deferred depreciation – NIPSCO obtained approval from the IURC to capitalize the debt-based carrying charges and deferred depreciation for Schahfer Unit 17 and Unit 18 due to regulatory lag and to amortize such costs over the remaining service life of each unit. | ||||||||
Unrecognized pension benefit and other postretirement benefit costs – In 2007, NiSource adopted certain updates of ASC 715 which required, among other things, the recognition in other comprehensive income or loss of the actuarial gains or losses and the prior service costs or credits that arise during the period but that are not immediately recognized as components of net periodic benefit costs. Certain subsidiaries defer the costs as a regulatory asset in accordance with regulatory orders or as a result of regulatory precedent, to be recovered through base rates. | ||||||||
Other postretirement costs – Primarily comprised of costs approved through rate orders to be collected through future base rates, revenue riders or tracking mechanisms. | ||||||||
Environmental costs – Includes certain recoverable costs of investigating, testing, remediating and other costs related to gas plant sites, disposal sites or other sites onto which material may have migrated. Certain companies defer the costs as a regulatory asset in accordance with regulatory orders, to be recovered in future base rates, billing riders or tracking mechanisms. | ||||||||
Regulatory effects of accounting for income taxes – Represents the deferral and under collection of deferred taxes in the rate making process. In prior years, NiSource has lowered customer rates in certain jurisdictions for the benefits of accelerated tax deductions. Amounts are expensed for financial reporting purposes as NiSource recovers deferred taxes in the rate making process. | ||||||||
Underrecovered gas and fuel costs – Represents the difference between the costs of gas and fuel and the recovery of such costs in revenue, and is used to adjust future billings for such deferrals on a basis consistent with applicable state-approved tariff provisions. Recovery of these costs is achieved through tracking mechanisms. | ||||||||
Depreciation – Primarily relates to the difference between the depreciation expense recorded by Columbia of Ohio due to a regulatory order and the depreciation expense recorded in accordance with GAAP. The regulatory asset is currently being amortized over the life of the assets. Also included is depreciation associated with the Columbia of Ohio IRP program and Capital Expenditure program. Recovery of these costs is achieved through base rates and rider mechanisms. Refer to Note 1-H for more information. | ||||||||
Uncollectible accounts receivable deferred for future recovery – Represents the difference between certain uncollectible expenses and the recovery of such costs to be collected through cost tracking mechanisms per regulatory orders. | ||||||||
Asset retirement obligations – Represents the timing difference between expense recognition for future obligations and current recovery in rates. | ||||||||
Losses on derivatives – Certain companies are permitted by regulatory orders to participate in commodity price programs to protect customers against the volatility of commodity prices. Unrealized and realized gains or losses related to NiSource’s commodity price risk programs may be deferred per specific orders and the recovery of changes in fair value is dependent upon the individual specific company’s cost recovery or sharing mechanisms in place. Amounts for derivative gains and losses will continue to be deferred as long as the programs are in existence. | ||||||||
Post-in-service carrying charges – Columbia of Ohio has approval from the PUCO by regulatory order to defer debt-based post-in-service carrying charges as a regulatory asset for future recovery. As such, Columbia of Ohio capitalizes a carrying charge on eligible property, plant and equipment from the time it is placed into utility service until recovery of the property, plant and equipment is included in customer rates in base rates or through a rider mechanism. Inclusion in customer rates generally occurs when Columbia of Ohio files its next rate proceeding following the in-service date of the property, plant and equipment. | ||||||||
EERM operation and maintenance and depreciation deferral – NIPSCO obtained approval from the IURC to recover certain environmental related costs including operation and maintenance and depreciation expense once the environmental facilities become operational. Recovery of these costs will continue until such assets are included in rate base through an electric base rate case. The EERM deferred charges represent expenses that will be recovered from customers through an annual EERM Cost Tracker which authorizes the collection of deferred balances over a twelve month period. | ||||||||
MISO – As part of NIPSCO’s participation in the MISO transmission service, wholesale energy and ancillary service markets, certain administrative fees and non-fuel costs have been deferred. The IURC authorized the deferral of certain non-fuel related costs until new electric rates were implemented on December 27, 2011. The deferred balances are being amortized over four years commencing January 2012. | ||||||||
Sugar Creek carrying charges and deferred depreciation – The IURC approved the deferral of debt-based carrying charges and the deferral of depreciation expense for the Sugar Creek assets. NIPSCO continued to defer such amounts until new electric rates were approved and implemented on December 27, 2011. Balances are being amortized over five years beginning January 2012. As of December 31, 2013, the remaining unamortized balance is $42.9 million. An additional $13.9 million is deferred for consideration in NIPSCO's next electric rate case. Management believes this amount is probable of recovery through future rates. | ||||||||
Liabilities: | ||||||||
Overrecovered gas and fuel costs – Represents the difference between the costs of gas and fuel and the recovery of such costs in revenues, and is the basis to adjust future billings for such recoveries on a basis consistent with applicable state-approved tariff provisions. Refunding of these revenues is achieved through tracking mechanisms. | ||||||||
Cost of removal – Represents anticipated costs of removal that have been, and continue to be, included in depreciation rates and collected in the service rates of the rate-regulated subsidiaries for future costs to be incurred. | ||||||||
Regulatory effects of accounting for income taxes – Represents amounts owed to customers for deferred taxes collected at a higher rate than the current statutory rates and liabilities associated with accelerated tax deductions owed to customers that are established during the rate making process. | ||||||||
Unrecognized pension benefit and other postretirement benefit costs – In 2007, NiSource adopted certain updates of ASC 715 which required, among other things, the recognition in other comprehensive income or loss of the actuarial gains or losses and the prior service costs or credits that arise during the period but that are not immediately recognized as components of net periodic benefit costs. Certain subsidiaries defer the costs as a regulatory liability in accordance with regulatory orders or as a result of regulatory precedent, to be refunded through base rates. | ||||||||
Other postretirement costs – Primarily represents cash contributions in excess of postretirement benefit expense that is deferred as a regulatory liability by certain subsidiaries in accordance with regulatory orders. | ||||||||
Percentage of income plan – Represents the difference between costs incurred under a customer assistance program by Columbia of Ohio for targeted low income customers and the recovery of such costs through cost tracking mechanisms per regulatory orders. For 2012, Columbia of Ohio was in an overcollected position for this program, which resulted in a regulatory liability that was refunded to customers. | ||||||||
Off-system sales margin sharing – Revenue generated from off-system sales and capacity release programs are subject to incentive sharing mechanism in which NiSource shares a defined percentage of its margins with customers. Refunding of these revenues is achieved through rate refund mechanisms. | ||||||||
Gas Distribution Operations Regulatory Matters | ||||||||
Significant Rate Developments. On April 30, 2013, Indiana Governor Pence signed Senate Enrolled Act 560 into law. Among other provisions, this legislation provides for cost recovery outside of a base rate proceeding for new or replacement electric and gas transmission, distribution, and storage projects that a public utility undertakes for the purposes of safety, reliability, system modernization, or economic development. The cost recovery mechanism is referred to as a TDSIC. Provisions of the TDSIC require that, among other things, requests for recovery include a seven year plan of eligible investments. Once the plan is approved by the IURC, 80 percent of eligible costs can be recovered using a periodic rate adjustment mechanism. Recoverable costs include a return on, and of, the investment, including AFUDC, post in service carrying charges, operation and maintenance expenses, depreciation, and property taxes. The remaining 20 percent of recoverable costs are to be deferred for future recovery in the public utility’s next general rate case. The periodic rate adjustment mechanism is capped at an annual increase of no more than two percent of total retail revenues. On October 3, 2013, NIPSCO filed its gas TDSIC seven year plan of eligible investments for a total of approximately $710 million with the IURC. An order is expected by the second quarter of 2014. | ||||||||
On June 18, 2013, NIPSCO, the OUCC and other customer stakeholder groups filed a unanimous agreement with the IURC to extend NIPSCO's 2010 natural gas customer rate settlement through 2020. The Settlement Agreement was approved by order issued on August 28, 2013 with the requirement that, on or before November 2020, NIPSCO must file a general rate case. | ||||||||
On December 28, 2011, the IURC issued an Order approving NIPSCO's proposed gas energy efficiency programs and budgets, including a conservation program and recovery of all start-up and deferred cost. A three year budget of $42.4 million was approved. | ||||||||
On November 25, 2013, 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 will file its Application by February 28, 2014. Columbia of Ohio will be seeking to increase revenues by approximately $30.5 million. | ||||||||
On November 30, 2012, 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 28, 2013 and indicated that Columbia of Ohio is seeking to increase revenues by approximately $29 million. A stipulation resolving all issues was filed on April 9, 2013, and a hearing was held on April 11, 2013. On April 24, 2013, the PUCO approved the stipulation. | ||||||||
On October 4, 2012, Columbia of Ohio filed a motion requesting an extension of its gas supply auction program, a continuation of its off-system sales and capacity release revenue sharing mechanism, and approval of its pipeline capacity contracts. On November 27, 2012, a non-unanimous stipulation resolving all issues was filed. After hearing, the PUCO issued an Order on January 9, 2013 that approved the stipulation. On May 1, 2013, the Ohio Partners for Affordable Energy appealed the PUCO Order to the Supreme Court of Ohio. The case has been briefed at the Supreme Court of Ohio, and the parties are awaiting the scheduling of oral argument. | ||||||||
On December 9, 2011, Columbia of Ohio filed a Notice of Intent to file an application to extend its IRP. Columbia of Ohio filed an amended Notice of Intent and an amended Motion for Waiver on March 5, 2012. On May 8, 2012, Columbia of Ohio filed its application, supporting exhibits and testimony. On September 26, 2012, the parties filed a Joint Stipulation and Recommendation that provided for the extension of Columbia of Ohio's IRP process for an additional five years and settlement of all issues. On November 28, 2012, the PUCO issued an Opinion and Order in which it approved the stipulation. | ||||||||
On May 29, 2013, Columbia of Kentucky filed an application with the Kentucky PSC requesting an increase of approximately $16.6 million in base rate revenues, the use of a forecasted test period and a revenue normalization adjustment to recognize changes in customer usage not included in Columbia of Kentucky's current weather normalization adjustment. A stipulation, signed by all parties and resolving all issues, was filed on November 5, 2013. On December 13, 2013, the Kentucky PSC issued an order approving the stipulation providing for, among other terms, an increase of $7.7 million in revenues using a forecasted test year, a recovery of Columbia of Kentucky’s investment in its pipeline replacement program on a forecasted basis, and continuation of Columbia of Kentucky's CHOICE program for three years. New rates were effective December 29, 2013. | ||||||||
On September 28, 2012, Columbia of Pennsylvania filed a base rate case with the Pennsylvania PUC, seeking a revenue increase of approximately $77.3 million annually and providing three options for residential rate design in order to mitigate revenue volatility associated with usage based rates. Columbia of Pennsylvania is the first utility in Pennsylvania to seek Pennsylvania PUC approval to design rates to recover costs that are projected to be incurred after the implementation of those new rates, as authorized by the Pennsylvania General Assembly with the passage of Act 11 of 2012. Accordingly, Columbia of Pennsylvania's filing sought to implement rates in July 2013 under which Columbia of Pennsylvania would immediately begin to recover costs that are projected for the twelve-month period ending June 30, 2014. On March 15, 2013, the parties to the rate case filed a joint petition formally seeking Pennsylvania PUC approval of a settlement featuring a revenue increase of $55.3 million annually and the implementation of a Weather Normalization Adjustment, whereby residential charges are adjusted in the event of winter temperatures that deviate from historic norms by plus or minus five percent. The Pennsylvania PUC issued an order approving the settlement on May 23, 2013, and new rates went into effect July 1, 2013. | ||||||||
On July 3, 2013, the VSCC issued an order approving an amendment to Columbia of Virginia's infrastructure tracking mechanism pursuant to the Steps to Advance Virginia's Energy (“SAVE”) Plan Act. Columbia of Virginia's five year SAVE Plan provides for recovery of costs associated with the accelerated replacement of certain facilities designed to improve system safety or reliability through a rate rider. The amendment increases authorized annual investments by $5.0 million from 2013 through 2016, to $25.0 million per year. In addition, the amendment expands the types of infrastructure eligible for the tracking mechanism and affords Columbia of Virginia additional flexibility with respect to annual and total plan limitations on expenditures. | ||||||||
On September 3, 2013, Columbia of Massachusetts and the Massachusetts Office of the Attorney General filed a Joint Motion for Approval of a Settlement Agreement with the Massachusetts DPU which resolves issues related to the disposition of revenues realized by Columbia of Massachusetts in 2005 from MASSPOWER's buy-out of a special contract with Columbia of Massachusetts, and which were at that time pending before the Massachusetts DPU in D.P.U. 10-10. The Settlement Agreement proposed to return $8.9 million to the customers of Columbia of Massachusetts in the form of a Distribution Rate Credit on their bills during the period November 1, 2013 through April 30, 2014. On October 16, 2013, the DPU issued an order approving the Settlement Agreement. | ||||||||
On April 16, 2013, Columbia of Massachusetts submitted a filing with the Massachusetts DPU requesting an annual revenue requirement increase of $30.1 million. An order is expected by February 28, 2014, with new rates going into effect on March 1, 2014. Pursuant to the procedural schedule for this case, on September 3, 2013, Columbia of Massachusetts filed its updated revenue requirement of $29.5 million and on October 16, 2013, filed an updated cost of service for $30 million. Evidentiary hearings and the briefing schedule for the case have concluded. In compliance with the procedural schedule, a final revenue requirements update of $29.9 million was filed on December 16, 2013. | ||||||||
On March 7, 2013, the Massachusetts DPU issued its final order approving $10.5 million of decoupling revenues for Columbia of Massachusetts' 2012-2013 Peak Period RDAF that was effective November 1, 2012 through April 30, 2013. | ||||||||
On April 13, 2012, Columbia of Massachusetts submitted a filing with the Massachusetts DPU requesting an annual revenue requirement increase of $29.2 million which was subsequently adjusted to $27.4 million. Columbia of Massachusetts filed using a historic test year ended December 31, 2011. Additionally, Columbia of Massachusetts proposed “rate-year, rate base” treatment for recovery of defined capital expenditures beyond the end of the historic test year, as well as expansion of eligible facilities to be recovered through modification to the TIRF. The Massachusetts DPU issued an order on November 1, 2012 approving an annual revenue increase of $7.8 million, effective November 1, 2012, rejecting the rate-year, rate-base proposal, but approving the expansion of eligible facilities to be recovered through the TIRF. | ||||||||
On August 2, 2013, Columbia of Massachusetts filed its 2013-2014 Peak Period LDAF and on September 16, 2013, Columbia of Massachusetts filed its 2013 Pension Expense Factor and its 2013 Residential Assistance Adjustment Factor, each with a proposed effective date of November 1, 2013. The 2013-2014 Peak Period LDAF of $59.0 million was approved on October 30, 2013, for effect November 1, 2013. The 2013 Pension Expense Factor and 2013 Residential Assistance Adjustment Factor, components of the LDAF, were approved subject to further investigation and reconciliation. | ||||||||
On August 2, 2012, Columbia of Massachusetts filed its 2012-2013 Peak Period LDAF and on September 14, 2012, Columbia of Massachusetts filed its 2012 Pension Expense Factor and 2012 Residential Assistance Adjustment Factor, each with a proposed effective date of November 1, 2012. The 2012-2013 Peak Period LDAF of $33.0 million effective November 1, 2012 was approved on October 31, 2012. The 2012 Pension Expense Factor and 2012 Residential Assistance Adjustment Factor components of the LDAF were approved subject to further investigation and reconciliation. | ||||||||
On February 27, 2013, Columbia of Maryland filed a base rate case with the Maryland PSC, seeking a revenue increase of approximately $5.3 million annually and seeking to implement a residential Revenue Normalization Adjustment in order to decouple revenues from customer usage and seeking to recover costs for environmental remediation associated with a former manufactured gas plant operated by a Columbia of Maryland predecessor in Hagerstown, Maryland, where a Columbia of Maryland service center is currently located. Hearings were held in June 2013. On September 23, 2013, the Maryland PSC issued an order that approved an annual revenue increase of $3.6 million, as well as Columbia of Maryland's proposed revenue normalization adjustment. The Maryland PSC permitted recovery of environmental remediation costs for the service center property, but denied recovery of the costs to acquire and remediate the adjacent property. On October 23, 2013, Columbia of Maryland filed a Petition for Judicial Review of the denial of the costs to acquire and remediate the adjacent property. New rates went into effect on September 25, 2013. | ||||||||
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 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 expenses. 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. | ||||||||
Columbia Pipeline Group Operations Regulatory Matters | ||||||||
Columbia Transmission Customer Settlement. On January 24, 2013, the FERC approved the Columbia Transmission Customer Settlement (the "Settlement"). In March 2013, Columbia Transmission paid $88.1 million in refunds to customers pursuant to the Settlement with its customers in conjunction with its comprehensive interstate natural gas pipeline modernization program. The refunds were made as part of the Settlement, which included a $50.0 million refund to max rate contract customers and a base rate reduction retroactive to January 1, 2012. Columbia Transmission expects to invest approximately $1.5 billion over a five-year period to modernize its system to improve system integrity and enhance service reliability and flexibility. The Settlement with firm customers includes an initial five-year term with provisions for potential extensions thereafter. | ||||||||
The Settlement also provided for a depreciation rate reduction to 1.5% and elimination of negative salvage rate effective January 1, 2012 and for a second base rate reduction, which began January 1, 2014, which equates to approximately $25 million in revenues annually thereafter. | ||||||||
The Settlement includes a CCRM, a tracker mechanism that will allow Columbia Transmission to recover, through an additive capital demand rate, its revenue requirement for capital investments made under Columbia Transmission's long-term plan to modernize its interstate transmission system. The CCRM provides for a 14% revenue requirement with a portion designated as a recovery of increased taxes other than income taxes. The additive demand rate is earned on costs associated with projects placed into service by October 31 each year. The initial additive demand rate was effective on February 1, 2014. The CCRM will give Columbia Transmission the opportunity to recover its revenue requirement associated with $1.5 billion investment in the modernization program, while maintaining competitive rates for its shippers. The CCRM recovers the revenue requirement associated with qualifying modernization costs that Columbia Transmission incurs after satisfying the requirement associated with $100 million in annual capital maintenance expenditures. The CCRM applies to Columbia Transmission's transportation shippers. The CCRM will not exceed $300 million per year in investment in eligible facilities, subject to a 15% annual tolerance and a total cap of $1.5 billion for the entire five-year initial term. On December 31, 2013, Columbia Transmission made its first annual CCRM filing, with billing rates effective February 1, 2014. Through this filing, Columbia Transmission will begin collecting its revenue requirements for the $299.2 million spent on eligible modernization facilities in 2013. For the first CCRM period, these revenue requirements will total approximately $38.9 million. On January 30, 2014, the FERC approved Columbia Transmission's first year CCRM filing. | ||||||||
Chesapeake, Virginia LNG Facility Modernization. In connection with long-term extensions of their expiring service agreements, the three customers of Columbia Transmission's Chesapeake, Virginia LNG peaking facility agreed to fund upgrades to modernize the facility. Under the settlement, Columbia Transmission will invest approximately $30.0 million to upgrade the facility and each customer will extend its contract for 15 years. The settlement was filed with the FERC on February 28, 2013 and approved without modification on June 3, 2013. The project's first phase was completed in the fourth quarter of 2013. The remainder of the project is expected to be completed by mid-2015. | ||||||||
Columbia Gulf Rate Case. On October 28, 2010, Columbia Gulf filed a rate case with the FERC, proposing a rate increase and tariff changes. Among other things, the filing proposed a revenue increase of approximately $50 million to cover increases in the cost of services, which includes adjustments for operation and maintenance expenses, capital investments, adjustments to depreciation rates and expense, rate of return, and increased federal, state and local taxes. On November 30, 2010, the FERC issued an Order allowing new rates to become effective by May 2011, subject to refund. Columbia Gulf placed new rates into effect, subject to refund, on May 1, 2011. Columbia Gulf and the active parties to the case negotiated a settlement, which was filed with the FERC on September 9, 2011. On September 30, 2011, the Chief Judge severed the issues relating to a contesting party for separate hearing and decision. On October 4, 2011, the Presiding Administrative Law Judge certified the settlement agreement as uncontested to the FERC with severance of the contesting party from the settlement. On November 1, 2011, Columbia Gulf began billing interim rates to customers. On December 1, 2011, the FERC issued an order approving the settlement without change. The key elements of the settlement, which was a “black box agreement”, include: (1) increased base rate to $0.1520 per Dth and (2) establishing a postage stamp rate design. No protests to the order were filed and therefore, pursuant to the Settlement, the order became final on January 1, 2012 which made the settlement effective on February 1, 2012. On February 2, 2012, the Presiding Administrative Law Judge issued an initial decision granting a joint motion terminating the remaining litigation with the contesting party and allowing it to become a settling party. The FERC issued an order on March 15, 2012, affirming the initial decision, which terminated the remaining litigation with the contesting party. Refunds of approximately $16.0 million, accrued as of December 31, 2011, were disbursed to settling parties in March 2012. | ||||||||
Cost Recovery Trackers and other similar mechanisms. 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 7 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, environmental, 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. As part of a multi-state effort to strengthen the electric transmission system serving the Midwest, NIPSCO anticipates making investments in two projects that were authorized by the MISO and are scheduled to be in service during the latter part of the decade. 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 the 100-mile, 345 kV transmission project and its right to develop 50 percent of the 66-mile, 765 kV project. On December 19, 2012, the FERC issued an order authorizing NIPSCO's request to transition to forward looking rates, allowing more timely recovery of NIPSCO's investment in transmission assets. On August 22, 2012, the IURC issued an order authorizing NIPSCO to retain certain revenues under MISO Schedule 26-A. NIPSCO began recording revenue in the first quarter of 2013 using a forward looking rate, based on an average construction work in progress balance of $19.8 million. For the twelve months ended December 31, 2013 revenue of $2.4 million was recorded. | ||||||||
On July 19, 2013, NIPSCO filed its electric TDSIC, further discussed above, 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, described above. NIPSCO anticipates filing its first semi-annual tracker petition in the third quarter of 2014. | ||||||||
On December 18, 2013, the IURC issued an Order approving NIPSCO's proposed electric energy efficiency programs and budgets through December 31, 2014, including authorization to use its energy efficiency recovery mechanism to recover costs and lost margins for 2014. | ||||||||
On November 12, 2013, several industrial customers, including INDIEC, filed a complaint at the FERC regarding the 12.38% base ROE used to set the MISO Transmission Owners' transmission rates and requesting a reduction in the base ROE to 9.15%. The complaint further requests that FERC limit the capital structure of MISO Transmission Owners to no more than 50% common equity for ratemaking purposes and that FERC eliminate incentive adders for membership in a RTO. NIPSCO joined in an answer defending the 12.38% base ROE and motion to dismiss the complaint filed on behalf of a group of MISO Transmission Owners on January 6, 2014. NIPSCO is unable to estimate the impact of this complaint or the timing of any potential impact at this time. | ||||||||
On July 18, 2011, NIPSCO filed with the IURC a settlement in its 2010 Electric Rate Case with the OUCC, Northern Indiana Industrial Group, NLMK Indiana and Indiana Municipal Utilities Group. The settlement agreement limited the proposed base rate impact to the residential customer class to a 4.5% increase. The parties also agreed to a rate of return of 6.98% based upon a 10.2% ROE. The settlement resolved all pending issues related to compliance with the August 25, 2010 Order in the 2008 Electric Rate Case. On December 21, 2011, the IURC issued an Order approving the Settlement Agreement as filed, and new electric base rates became effective on December 27, 2011. | ||||||||
During 2002, NIPSCO settled certain regulatory matters related to an electric rate review. On September 23, 2002, the IURC issued an Order adopting most aspects of the settlement. The Order approving the settlement provided that certain electric customers of NIPSCO would receive bill credits of approximately $55.1 million each year. The credits continued at approximately the same annual level and per the same methodology, until the IURC approval and implementation of new customer rates, which occurred on December 27, 2011. Credits amounting to $51.0 million were recognized for electric customers for 2011. A final reconciliation of the credits was completed in the fourth quarter of 2012, which resulted in recoveries of $6.6 million in 2012. | ||||||||
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. | ||||||||
On December 9, 2009, the IURC issued an Order in its generic DSM investigation proceeding establishing an overall annual energy savings goal of 2% to be achieved by Indiana jurisdictional electric utilities in 10 years, with interim savings goals established in years one through nine. On May 25, 2011, the IURC issued an Order approving a tracker mechanism to recover the costs associated with these energy efficiency programs. On July 27, 2011, the IURC issued an order approving NIPSCO's portfolio of electric energy efficiency programs and on August 8, 2012, approved recovery of lost margins associated with those programs through semi-annual tracker filings. | ||||||||
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 October 30, 2013, the IURC issued an order on ECR-22 approving NIPSCO’s request to begin earning a return on $478.8 million of net capital expenditures. On January 31, 2014, NIPSCO filed ECR-23 which included $583.5 million of net capital expenditures for the period ending December 31, 2013. | ||||||||
On October 10, 2013, the IURC issued an order approving NIPSCO’s MATS Compliance Projects. Refer to Note 20-D, “Environmental Matters,” for additional information on the MATS rule. The Order approved estimated capital costs of $59.3 million and granted the requested ratemaking relief and accounting treatment associated with these projects through the annual EERM and semi-annual ECRM tracker filings. | ||||||||
On March 22, 2011, NIPSCO filed a petition with the IURC for a certificate of public convenience and necessity and associated relief for the construction of additional environmental projects required to comply with the NOV consent decree lodged in the United States District Court for the Northern District of Indiana on January 13, 2011 and EPA Regulations. Refer to Note 20-D, “Environmental Matters,” for additional information. This petition was trifurcated into three separate phases. On December 28, 2011, February 15, 2012 and September 5, 2012, the IURC issued orders approving estimated project costs of approximately $800.0 million and granting the requested ratemaking and accounting relief associated with these projects through annual and semi-annual tracker filings. |

Derivative Instruments and Hedges, Assets [Abstract] | ' | |||||||||||||||||||
Risk Management Activities | ' | |||||||||||||||||||
Risk Management Activities | ||||||||||||||||||||
NiSource is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are commodity price risk and interest rate risk. Derivative natural gas contracts are entered into to manage the price risk associated with natural gas price volatility and to secure forward natural gas prices. Interest rate swaps are entered into to manage interest rate risk or fair value risk associated with NiSource’s borrowings. NiSource designates some of its commodity forward contracts as cash flow hedges of forecasted purchases of commodities and designates its interest rate swaps as fair value hedges of fixed-rate borrowings. Additionally, certain NiSource subsidiaries enter into forward physical contracts with various third parties to procure or sell natural gas or power. Certain forward physical contracts are derivatives which qualify for, and for which NiSource may elect, the normal purchase and normal sales exception which do not require mark-to-market accounting. | ||||||||||||||||||||
Accounting Policy for Derivative Instruments. The ASC topic on accounting for derivatives and hedging requires an entity to recognize all derivatives as either assets or liabilities on the Consolidated Balance Sheets at fair value, unless such contracts are exempted, such as normal purchase and normal sale contracts, under the provisions of the ASC topic. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and resulting designation. | ||||||||||||||||||||
NiSource uses a variety of derivative instruments (exchange traded futures and options, physical forwards and options, commodity swaps and interest rate swaps) to effectively manage its commodity price risk and interest rate risk exposure. If certain conditions are met, a derivative may be specifically designated as (a) a hedge of the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment, or (b) a hedge of the exposure to variable cash flows of a forecasted transaction. In order for a derivative contract to be designated as a hedge, the relationship between the hedging instrument and the hedged item or transaction must be highly effective. The effectiveness test is performed at the inception of the hedge and each reporting period thereafter, throughout the period that the hedge is designated. Any amounts determined to be ineffective are recognized currently in earnings. For derivative contracts that qualify for the normal purchase and normal sales exception, a contract’s fair value is not recognized in the Consolidated Financial Statements until the contract is settled. | ||||||||||||||||||||
Unrealized and realized gains and losses are recognized each period as components of AOCI, regulatory assets and liabilities or earnings depending on the designation of the derivative instrument and regulatory accounting treatment. For subsidiaries that utilize derivatives for cash flow hedges, the effective portions of the gains and losses are recorded to AOCI and are recognized in earnings concurrent with the disposition of the hedged risks. If a forecasted transaction corresponding to a cash flow hedge is no longer probable to occur, the accumulated gains or losses on the derivative are recognized currently in earnings. For fair value hedges, the gains and losses are recorded in earnings each period together with the change in the fair value of the hedged item. As a result of the rate-making process, the rate-regulated subsidiaries generally record gains and losses as regulatory liabilities or assets and recognize such gains or losses in earnings when both the contracts settle and the physical commodity flows. These gains and losses recognized in earnings are then subsequently recovered or passed back to customers in revenues through rates. When gains and losses are recognized in earnings, they are recognized in revenues or cost of sales for derivatives that correspond to commodity risk activities and are recognized in interest expense for derivatives that correspond to interest-rate risk activities. | ||||||||||||||||||||
For its commodity price risk programs, NiSource has elected not to net the fair value amounts of its derivative instruments or the fair value amounts recognized for its right to receive or obligation to pay cash collateral arising from those derivative instruments recognized at fair value, which are executed with the same counterparty under a master netting arrangement. NiSource discloses amounts recognized for the right to reclaim cash collateral within “Restricted cash” and amounts recognized for the obligation to return cash collateral within “Other accruals” on the Consolidated Balance Sheets. | ||||||||||||||||||||
Commodity Price Risk Programs. NiSource and NiSource’s utility customers are exposed to variability in cash flows associated with natural gas purchases and volatility in natural gas prices. NiSource purchases natural gas for sale and delivery to its retail, commercial and industrial customers, and for most customers the variability in the market price of gas is passed through in their rates. Some of NiSource’s utility subsidiaries offer programs where variability in the market price of gas is assumed by the respective utility. The objective of NiSource’s commodity price risk programs is to mitigate this gas cost variability, for NiSource or on behalf of its customers, associated with natural gas purchases or sales by economically hedging the various gas cost components by using a combination of futures, options, forward physical contracts or other derivative contracts. NIPSCO also uses derivative contracts to minimize risk associated with power price volatility. These commodity price risk programs and their respective accounting treatment are described below. | ||||||||||||||||||||
NIPSCO, Columbia of Pennsylvania, Columbia of Kentucky and Columbia of Virginia use NYMEX futures and NYMEX options to minimize risk associated with gas price volatility. These derivative programs must be marked to fair value, but because these derivatives are used within the framework of the companies’ GCR or FAC mechanism, regulatory assets or liabilities are recorded to offset the change in the fair value of these derivatives. | ||||||||||||||||||||
NIPSCO and Columbia of Virginia offer a fixed price program as an alternative to the standard GCR mechanism. These services provide certain customers with the opportunity to either lock in their gas cost or place a cap on the gas costs that would be charged in future months. In order to hedge the anticipated physical purchases associated with these obligations, forward physical contracts, NYMEX futures and NYMEX options are used to secure forward gas prices. The accounting treatment elected for these contracts is varied in that certain of these contracts have been accounted for as cash flow hedges while some contracts are not. The accounting treatment is based on the election of the company. The normal purchase and normal sales exception is elected for forward physical contracts associated with these programs where delivery of the commodity is probable to occur. | ||||||||||||||||||||
NIPSCO also offers a DependaBill program to its customers as an alternative to the standard tariff rate that is charged to residential customers. The program allows NIPSCO customers to fix their total monthly bill in future months at a flat rate regardless of gas usage or commodity cost. In order to hedge the anticipated physical purchases associated with these obligations, forward physical contracts, NYMEX futures and NYMEX options have been used to secure forward gas prices. The normal purchase and normal sales exception is elected for forward physical contracts associated with these programs where delivery of the commodity is probable to occur. | ||||||||||||||||||||
NIPSCO enters into gas purchase contracts at first of the month prices that give counterparties the daily option to either sell an additional package of gas at first of the month prices or recall the original volume to be delivered. NIPSCO charges a fee for this option. The changes in the fair value of these options are primarily due to the changing expectations of the future intra-month volatility of gas prices. These written options are derivative instruments, must be marked to fair value and do not meet the requirement for hedge accounting treatment. However, NIPSCO records the related gains and losses associated with these transactions as a regulatory asset or liability. | ||||||||||||||||||||
Columbia of Kentucky, Columbia of Ohio and Columbia of Pennsylvania enter into contracts that allow counterparties the option to sell gas to them at first of the month prices for a particular month of delivery. These Columbia LDCs charge the counterparties a fee for this option. The changes in the fair value of the options are primarily due to the changing expectations of the future intra-month volatility of gas prices. These Columbia LDCs defer a portion of the change in the fair value of the options as either a regulatory asset or liability based on the regulatory customer sharing mechanisms in place, with the remaining changes in fair value recognized currently in earnings. | ||||||||||||||||||||
As part of the MISO Day 2 initiative, NIPSCO was allocated or has purchased FTRs. These FTRs help NIPSCO offset congestion costs due to the MISO Day 2 activity. The FTRs are marked to fair value and are not accounted for as a hedge, but since congestion costs are recoverable through the fuel cost recovery mechanism, the related gains and losses associated with marking these derivatives to market are recorded as a regulatory asset or liability. In the second quarter of 2008, MISO changed its allocation procedures from an allocation of FTRs to an allocation of ARRs, whereby NIPSCO was allocated ARRs based on its historical use of the MISO administered transmission system. ARRs entitle the holder to a stream of revenues or charges based on the price of the associated FTR in the FTR auction, so ARRs can be used to purchase FTRs in the FTR auction. ARRs are not derivatives. | ||||||||||||||||||||
During the fourth quarter of 2011, NiSource recorded a reserve of $22.6 million on certain assets related to the wind-down of the unregulated natural gas marketing business. During 2012, NiSource settled a majority of the contracts related to the reserve noted above and wrote off $43.8 million of price risk assets. On September 1, 2013, NiSource sold the commercial and industrial natural gas portfolio of its unregulated natural gas marketing business. The sale included the physical contracts and associated financial hedges that comprise the portfolio, as well as the gas inventory and customer deposits of the business. The physical sales contracts marked-to-market had a fair value of approximately $35.4 million at December 31, 2012, while the financial derivative contracts marked-to-market had a fair value loss of $33.2 million at December 31, 2012. These amounts have been reclassified to held for sale as of December 31, 2012. Refer to Note 4, "Discontinued Operations and Assets and Liabilities Held for Sale" for additional information regarding the transaction. | ||||||||||||||||||||

Interest Rate Risk Activities. NiSource recognizes that the prudent and selective use of derivatives may help it to lower its cost of debt capital and manage its interest rate exposure. NiSource Finance has entered into various “receive fixed” and “pay floating” interest rate swap agreements which modify the interest rate characteristics of a portion of its outstanding long-term debt from fixed to variable rate. These interest rate swaps also serve to hedge the fair market value of NiSource Finance’s outstanding debt portfolio. As of December 31, 2013, NiSource had $7.7 billion of outstanding fixed rate debt, of which $500 million is subject to fluctuations in interest rates as a result of the fixed-to-variable interest rate swap transactions. These interest rate swaps are designated as fair value hedges. NiSource had no net gain or loss recognized in earnings due to hedging ineffectiveness for the twelve months ended December 31, 2013, 2012, and 2011. | ||||||||||||||||||||
On July 22, 2003, NiSource Finance entered into fixed-to-variable interest rate swap agreements in a notional amount of $500 million with four counterparties which will expire on July 15, 2014. NiSource Finance receives payments based upon a fixed 5.40% interest rate and pays a floating interest amount based on U.S. 6-month BBA LIBOR plus an average of 0.78% per annum. There was no exchange of premium at the initial date of the swaps. | ||||||||||||||||||||
Contemporaneously with the issuance on September 16, 2005 of $1 billion of its 5.25% and 5.45% notes, maturing September 15, 2017 and 2020, respectively, NiSource Finance settled $900 million of forward starting interest rate swap agreements with six counterparties. NiSource paid an aggregate settlement payment of $35.5 million which is being amortized from accumulated other comprehensive loss to interest expense over the term of the underlying debt, resulting in an effective interest rate of 5.67% and 5.88%, respectively. As of December 31, 2013, accumulated other comprehensive loss includes $8.2 million related to forward starting interest rate swap settlement. These derivative contracts are accounted for as a cash flow hedge. | ||||||||||||||||||||
As of December 31, 2013, NiSource holds a 47.5% interest in Millennium. As NiSource reports Millennium as an equity method investment, NiSource is required to recognize a proportional share of Millennium’s OCI. NiSource’s proportionate share of the remaining unrealized loss associated with a settled interest rate swap is $17.7 million, net of tax, as of December 31, 2013. Millennium is amortizing the unrealized loss related to these terminated interest rate swaps into earnings using the effective interest method through interest expense as interest payments are made. NiSource records its proportionate share of the amortization as Equity Earnings in Unconsolidated Affiliates in the Statements of Consolidated Income. | ||||||||||||||||||||

Certain NiSource affiliates have physical commodity purchase agreements that contain “ratings triggers” that require increases in collateral if the credit rating of NiSource or certain of its affiliates are rated below BBB- by Standard & Poor’s or below Baa3 by Moody’s. These agreements are primarily for the physical purchase or sale of natural gas and electricity. As of December 31, 2013, the collateral requirement from a downgrade below the ratings trigger levels would amount to approximately $0.9 million. In addition to agreements with ratings triggers, there are some agreements that contain “adequate assurance” or “material adverse change” provisions that could result in additional credit support such as letters of credit and cash collateral to transact business. | ||||||||||||||||||||
NiSource had $5.9 million and $45.7 million of cash on deposit with brokers for margin requirements associated with open derivative positions reflected within “Restricted cash” on the Consolidated Balance Sheets as of December 31, 2013 and December 31, 2012, respectively. |

Variable Interest Entities and Equity Method Investments | ||||||||||||
A.Variable Interest Entities. In general, a VIE is an entity which (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 other 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. Prior to the adoption of the FASB guidance on consolidation of variable interest entities, the prevalent method for determining the primary beneficiary was through a quantitative method. With the adoption of the guidance, NiSource also considers qualitative elements in determining the primary beneficiary. These qualitative measures include the ability to control an entity and the obligation to absorb losses or the right to receive benefits. | ||||||||||||
NiSource’s analysis under GAAP 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 variable interest entity, 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. Services under this contract commenced on July 1, 1992 and expired on June 30, 2012. The agreement was renewed effective July 1, 2012 for ten years and NIPSCO will continue to pay for the services under a combination of fixed and variable charges. NiSource has made an exhaustive effort to obtain information needed from Pure Air to determine the status of Pure Air as a VIE. However, NIPSCO has not been able to obtain this information and as a result, it is unclear whether Pure Air is a VIE and if NIPSCO is the primary beneficiary. NIPSCO will continue to request the information required to determine whether Pure Air is a VIE. NIPSCO has no exposure to loss related to the service agreement with Pure Air and payments under this agreement were $23.6 million and $21.6 million for the years ended December 31, 2013 and 2012, respectively. In accordance with GAAP, the renewed agreement was evaluated to determine whether the arrangement qualifies as a lease. Based on the terms of the agreement, the arrangement qualified for capital lease accounting. As the effective date of the new agreement was July 1, 2012, NiSource capitalized this lease beginning in the third quarter of 2012. | ||||||||||||
B.Equity Method Investments. Certain investments of NiSource are accounted for under the equity method of accounting. Income and losses from Millennium and Hardy Storage are reflected in Equity Earnings in Unconsolidated Affiliates on NiSource’s Statements of Consolidated Income. These investments are integral to the Columbia Pipeline Group Operations business. Income and losses from all other equity investments are reflected in Other, net on NiSource’s Statements of Consolidated Income. All investments shown as limited partnerships are limited partnership interests. | ||||||||||||

As the Millennium and Hardy Storage investments are considered integral to the Columbia Pipeline Group Operations business, the following table contains condensed summary financial data. These investments are accounted for under the equity method of accounting and, therefore, are not consolidated into NiSource’s Consolidated Balance Sheets and Statements of Consolidated Income. These investments are recorded within Unconsolidated affiliates on the Consolidated Balance Sheets and NiSource’s portion of the results is reflected in Equity Earnings in Unconsolidated Affiliates on the Statements of Consolidated Income. | ||||||||||||
Given the immaterial nature of the other equity method investments, a condensed summary of financial data was determined not to be necessary. | ||||||||||||

The effective income tax rates were 34.8%, 34.4% and 35.0% in 2013, 2012 and 2011, respectively. The change in the overall effective tax rate between 2013, 2012, and 2011 was minimal. | |||||||||||||||||||||
On July 24, 2013, Transportation Finance Bill H3535, which was passed by the Massachusetts legislature, repealed the reduced tax rate of 6.5% for public utility corporations contained in Section 52A of Chapter 63 of the Massachusetts General Laws. Effective January 1, 2014, Columbia of Massachusetts will be taxed at 8.0%, which is the current franchise tax rate for corporations that are not public utilities. Deferred income tax expense was adjusted by $1.2 million as a result of this law change. | |||||||||||||||||||||
On March 7, 2013, the Congressional Joint Committee on Taxation took no exception to the conclusions reached by the IRS in its 2008-2010 audit examination of NiSource. Therefore, in the first quarter of 2013, NiSource recognized a federal income tax receivable of $15.9 million that was related to the 2008 and 2009 tax years and increases in net operating loss carryforwards of $0.6 million that was related to uncertain tax positions in the 2010-2012 tax years. NiSource received payments of $75.1 million in March 2013 and $70.6 million in April 2013 of principal and interest from the IRS related to the audit examination. The recognition of the receivables and net operating loss carryforwards did not materially affect tax expense or net income. | |||||||||||||||||||||
On January 2, 2013, the President signed into law the American Taxpayer Relief Act of 2012 (ATRA). ATRA, among other things, extended retroactively the research credit under Internal Revenue Code section 41 until December 31, 2013, and also extended and modified 50% bonus depreciation for 2013. In general, 50% bonus depreciation is available for property placed in service before January 1, 2014, or in the case of certain property having longer production periods, before January 1, 2015. NiSource recorded the effects of ATRA in the first quarter 2013. The retroactive extension of the research credit did not have a significant effect on net income. | |||||||||||||||||||||
On May 12, 2011, the governor of Indiana signed into law House Bill 1004, which among other things, lowered the corporate income tax rate from 8.5% to 6.5% over four years beginning on July 1, 2012. The reduction in the tax rate impacted deferred income taxes and tax related regulatory assets and liabilities recoverable in the rate making process. In addition, other deferred tax assets and liabilities, primarily deferred tax assets related to Indiana net operating loss carry forward, was reduced to reflect the lower rate at which these temporary differences and tax benefits will be realized. In the second quarter 2011, NiSource recorded tax expense of $6.8 million to reflect the effect of this rate change. The expense is largely attributable to the re-measurement of the Indiana net operating loss at the 6.5% rate. The majority of the Company’s tax temporary differences are related to NIPSCO’s utility plant. The re-measurement of these temporary differences at 6.5% was recorded as a reduction of a regulatory asset. | |||||||||||||||||||||
In the fourth quarter of 2010, NiSource received permission from the IRS to change its method of accounting for capitalized overhead costs under Section 263A of the Internal Revenue Code. The change was effective for the 2009 tax year. The Company recorded a net long-term receivable of $31.5 million, net of uncertain tax positions, in the fourth quarter of 2010 to reflect this change. There was no material impact on the effective tax rate as a result of this method change. In 2011, the Company revised its calculation related to the change in method and recorded an increase to the net long-term receivable of $3.3 million, net of uncertain tax positions, to reflect the change in estimate. Excluding minor amounts of interest, the revision in estimate did not impact total income tax expense. In 2012, the IRS completed fieldwork for the audit for the years 2008-2010, and the change in method was accepted substantially as filed. Joint committee review was completed in 2013 without adjustment. | |||||||||||||||||||||
In the third quarter of 2010, NiSource recorded a $15.2 million reduction to income tax expense in connection with the Pennsylvania PUC approval a Columbia of Pennsylvania base rate case settlement on August 18, 2010. The adjustment to income tax expense resulted from the settlement agreement to flow through in current rates the tax benefits related to a tax accounting method change for certain capitalized costs approved by the IRS. As a result of the Pennsylvania PUC Order on October 14, 2011, Columbia of Pennsylvania continued to flow through in rates unamortized tax benefits of approximately $15.6 million through January 2014 related to the unit of property tax method change. As a result of a Pennsylvania PUC Order dated May 23, 2013, Columbia of Pennsylvania adjusted the flow through in rates of tax benefits so that the unamortized balance of approximately $8.2 million at June 30, 2013 would be amortized through December 2016. The amortization of excess tax benefits was $9.5 million in 2013. On a prospective basis, Columbia of Pennsylvania will recognize deferred tax expense rather than flow through in rates the tax benefits resulting from this method change. | |||||||||||||||||||||
Tangible Property Regulations and Repairs | |||||||||||||||||||||
During the third quarter of 2009, NiSource received permission from the IRS to change its tax method of capitalizing certain costs which it applied on a prospective basis to the federal and state income tax returns filed for its 2008 tax year. As a result of the new tax accounting method, NiSource recorded federal and state income tax receivables of $295.7 million. Refunds of $263.5 million were received in October 2009, with additional refunds of $25.3 million received in December 2009 and January and February 2010. The balance of the refunds was received during 2010. | |||||||||||||||||||||
On August 19, 2011, the IRS issued Revenue Procedure 2011-43, which provided a safe harbor method that taxpayers may use to determine whether certain expenditures related to electric transmission and distribution assets must be capitalized. This revenue procedure provided procedures for obtaining automatic consent from the IRS to adopt the safe harbor method for the first or second taxable year beginning after December 30, 2010. NiSource changed its method of tax accounting related to certain expenditures, including those related to electric transmission and distribution assets, in 2008. At December 31, 2011 and 2010, NiSource had $80.9 million and $107.4 million, respectively, of unrecognized tax benefits related to this method change pending resolution on audit or further guidance from the IRS or United States Treasury Department. As a result of the issuance of the revenue procedure NiSource revised its estimates and recorded tax benefits of $12.9 million in the third quarter of 2011. Excluding minor amounts of interest, the revision of estimate did not impact total income tax expense. On its 2011 federal income tax return filed in September 2012, NiSource included an automatic change in tax accounting method related to electric transmission and distribution repairs in conformity with Revenue Procedure 2011-43. | |||||||||||||||||||||
On December 27, 2011, the United States Treasury Department and the IRS issued temporary and proposed regulations effective for years beginning on or after January 1, 2012 that, among other things, provided guidance on whether expenditures qualified as deductible repairs (the “Tangible Property Regulations”). In addition to repairs related rules, the proposed and temporary regulations provided additional guidance related to capitalization of tangible property. Among other things, these rules provide guidance for the treatment of materials and supplies, dispositions of property, and related elections. On March 15, 2012, the IRS issued a directive to discontinue exam activity related to positions on this issue taken on original tax returns for years beginning before January 1, 2012 (commonly referred to as the “Stand-down Position”). | |||||||||||||||||||||
On October 2, 2012 and later incorporated by reference in the Revenue Agent's Report dated November 14, 2012 for the 2008 to 2010 tax years, NiSource received an audit adjustment that adopted the Stand-down Position. The effect of this adjustment is to allow the repairs claims as filed and to defer review until a new method is adopted in 2012 or a subsequent acceptable year. | |||||||||||||||||||||
On November 20, 2012, the Treasury Department and IRS issued Notice 2012-73, which in relevant part stated that (i) final regulations would be issued in 2013, and (ii) the final regulations will contain changes from the temporary regulations. The Notice in essence defers the requirement of adopting the temporary regulations until 2013 and the final regulations until 2014. | |||||||||||||||||||||
On September 13, 2013, the IRS and U.S. Treasury issued final regulations on the deductibility and capitalization of expenditures related to tangible property, generally effective for tax years beginning on or after January 1, 2014. Taxpayers may elect early adoption of the regulations for the 2012 or 2013 tax year. NiSource does not plan to early adopt the regulations. The final regulations do not impact the effect of Revenue Procedure 2013-24 issued on April 30, 2013 which provided guidance for repairs related to generation property. Among other things, the Revenue Procedure listed units of property and material components of units of property for purposes of analyzing repair versus capitalization issues. NiSource will likely adopt this Revenue Procedure for income tax filings in 2014. NiSource has evaluated the impact of the final regulations and Revenue Procedure and has determined that they do not materially affect the financial statements. | |||||||||||||||||||||
Deferred income taxes result from temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. The principal components of NiSource’s net deferred tax liability were as follows: | |||||||||||||||||||||

State income tax net operating loss benefits were recorded at their realizable value. NiSource anticipates it is more likely than not that it will realize $39.8 million and $39.4 million of these benefits as of December 31, 2013 and December 31, 2012, respectively, prior to their expiration. The remaining net operating loss carry forward represents a Federal carry forward of $298.9 million that will expire in 2033 and an Alternative Minimum Tax credit of $4.7 million that will carry forward indefinitely. The state amounts are primarily for Indiana, Pennsylvania, and West Virginia. The loss carryforward periods expire in various tax years from 2025 through 2033. | |||||||||||||||||||||
A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows: | |||||||||||||||||||||

Based upon its intent to comply with Internal Revenue Procedures, Tangible Property Regulations and the Stand-down Position audit adjustment, NiSource determined that the unrecognized tax benefit associated with the requested change in tax accounting method filed for 2008 related to electric generation and gas transmission and distribution required a re-measurement under the provisions of ASC 740. Therefore, in the fourth quarter of 2012 NiSource recognized an income tax receivable of $85.7 million related to the 2008 and 2009 tax years and increases in net operating loss carryforwards of $6.8 million for the tax years 2010-2012, previously unrecognized. Except for interest recorded on the tax receivables, the recognition of the receivables and net operating loss carryforwards did not materially affect tax expense or net income. The IRS issued Revenue Procedure 2013-24 on April 30, 2013, which provided guidance for repairs related to generation property. Among other things, the Revenue Procedure listed units of property and material components of units of property for purposes of analyzing repair versus capitalization issues. NiSource will likely adopt this Revenue Procedure for income tax filings in 2014. NiSource has evaluated and recorded the effect of the change in method enabled by this Revenue Procedure as of December 31, 2013. | |||||||||||||||||||||
In 2010, NiSource received permission to change its method of accounting for capitalizing overhead costs. The Company recorded an unrecognized tax benefit related to this uncertain tax position of $17.6 million in 2010. In 2011, this estimate was revised to $19.9 million. In 2012, the IRS completed fieldwork for the audit for the years 2008-2010, pending Joint Committee review. The Company revised the unrecognized tax benefit related to this issue to incorporate 2012 activity. At December 31, 2012, the unrecognized tax benefits were $21.1 million. This issue was resolved in 2013. | |||||||||||||||||||||
Offsetting the liability for unrecognized tax benefits are $23.0 million of related outstanding tax receivables and net operating loss carryforwards resulting in a net balance of $0.7 million, including interest, related to the tax method change issues. | |||||||||||||||||||||
Except as discussed above, there have been no other material changes in 2013 to NiSource's uncertain tax positions recorded as of December 31, 2012. | |||||||||||||||||||||
The total amount of unrecognized tax benefits at December 31, 2013, 2012 and 2011 that, if recognized, would affect the effective tax rate is $4.0 million, $2.2 million and $2.4 million, respectively. As of December 31, 2013, NiSource did not anticipate any significant changes to its liabilities for unrecognized tax benefits over the twelve months ended December 31, 2014. As of December 31, 2012, it was reasonably possible that a $20.5 million decrease in unrecorded tax benefits could occur in 2013 due primarily to Joint Committee Taxation review of the 2008-2010 federal audit. The results of the review are described above. | |||||||||||||||||||||
NiSource recognizes accrued interest on unrecognized tax benefits, accrued interest on other income tax liabilities, and tax penalties in income tax expense. With respect to its unrecognized tax benefits, NiSource recorded $(0.8) million, $0.2 million and $(0.1) million in interest expense in the Statements of Consolidated Income for the years ended December 31, 2013, 2012 and 2011, respectively. For the years ended December 31, 2013, 2012 and 2011, NiSource reported $0.1 million, $0.9 million and $0.7 million, respectively, of accrued interest payable on unrecognized tax benefits on its Consolidated Balance Sheets. There were no accruals for penalties recorded in the Statement of Consolidated Income for the years ended December 31, 2013, 2012 and 2011 and there were no balances for accrued penalties recorded on the Consolidated Balance Sheets as of December 31, 2013 and December 31, 2012. | |||||||||||||||||||||
NiSource is subject to income taxation in the United States and various state jurisdictions, primarily Indiana, West Virginia, Virginia, Pennsylvania, Kentucky, Massachusetts, Louisiana, Mississippi, Maryland, Tennessee, New Jersey and New York. | |||||||||||||||||||||
Because NiSource is part of the IRS's Large and Mid-Size Business program, each year's federal income tax return is typically audited by the IRS. As of December 31, 2013, tax years through 2010 have been audited and are effectively closed to further assessment, except for immaterial carryforward amounts. The audit of tax years 2011 and 2012 began in the first quarter of 2013. NiSource is also involved in the Compliance Assurance Program. | |||||||||||||||||||||
The statute of limitations in each of the state jurisdictions in which NiSource operates remain open until the years are settled for federal income tax purposes, at which time amended state income tax returns reflecting all federal income tax adjustments are filed. As of December 31, 2013, there were no state income tax audits in progress that would have a material impact on the consolidated financial statements. |

Pension and Other Postretirement Benefits | ||||||||||||||||||||||||
NiSource provides defined contribution plans and noncontributory defined benefit retirement plans that cover the majority of its employees. Benefits under the defined benefit retirement plans reflect the employees’ compensation, years of service and age at retirement. Additionally, NiSource provides health care and life insurance benefits for certain retired employees. The majority of employees may become eligible for these benefits if they reach retirement age while working for NiSource. The expected cost of such benefits is accrued during the employees’ years of service. Current rates of rate-regulated companies include postretirement benefit costs, including amortization of the regulatory assets that arose prior to inclusion of these costs in rates. For most plans, cash contributions are remitted to grantor trusts. | ||||||||||||||||||||||||
NiSource Pension and Other Postretirement Benefit Plans’ Asset Management. NiSource employs a total return investment approach whereby a mix of equities and fixed income investments are used to maximize the long-term return of plan assets for a prudent level of risk. Risk tolerance is established through careful consideration of plan liabilities, plan funded status, and asset class volatility. The investment portfolio contains a diversified blend of equity and fixed income investments. Furthermore, equity investments are diversified across U.S. and non-U.S. stocks, as well as growth, value, small and large capitalizations. Other assets such as private equity funds are used judiciously to enhance long-term returns while improving portfolio diversification. Derivatives may be used to gain market exposure in an efficient and timely manner; however, derivatives may not be used to leverage the portfolio beyond the market value of the underlying assets. Investment risk is measured and monitored on an ongoing basis through quarterly investment portfolio reviews, annual liability measurements, and periodic asset/liability studies. | ||||||||||||||||||||||||
NiSource utilizes a building block approach with proper consideration of diversification and rebalancing in determining the long-term rate of return for plan assets. Historical markets are studied and long-term historical relationships between equities and fixed income are analyzed to ensure that they are consistent with the widely accepted capital market principle that assets with higher volatility generate greater return over the long run. Current market factors such as inflation and interest rates are evaluated before long-term capital market assumptions are determined. Peer data and historical returns are reviewed to check for reasonability and appropriateness. | ||||||||||||||||||||||||
The most important component of an investment strategy is the portfolio asset mix, or the allocation between the various classes of securities available to the pension and other postretirement benefit plans for investment purposes. The asset mix and acceptable minimum and maximum ranges established for the NiSource plan assets represents a long-term view and are listed in the following table. | ||||||||||||||||||||||||
In 2012, a dynamic asset allocation policy for the pension fund was approved. This policy calls for a gradual reduction in the allocation to return-seeking assets (equities, real estate, private equity and hedge funds) and a corresponding increase in the allocation to liability-hedging assets (fixed income) as the funded status of the plans increase above 90% (as measured by the projected benefit obligations of the qualified pension plans divided by the market value of qualified pension plan assets). The asset mix and acceptable minimum and maximum ranges established by the policy for the pension fund at the pension plans funded status on December 31, 2013 are as follows: | ||||||||||||||||||||||||

Fair Value Measurements. The following table sets forth, by level within the fair value hierarchy, the Master Trust and OPEB investment assets at fair value as of December 31, 2013 and 2012. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Total Master Trust and OPEB investment assets at fair value classified within Level 3 were $124.7 million and $326.7 million as of December 31, 2013 and December 31, 2012, respectively. Such amounts were approximately 5% and 13% of the Master Trust and OPEB’s total investments as reported on the statement of net assets available for benefits at fair value as of December 31, 2013 and 2012, respectively. | ||||||||||||||||||||||||
Valuation Techniques Used to Determine Fair Value: | ||||||||||||||||||||||||
Level 1 Measurements | ||||||||||||||||||||||||
Most common and preferred stock are traded in active markets on national and international securities exchanges and are valued at closing prices on the last business day of each period presented. Cash is stated at cost which approximates their fair value, with the exception of cash held in foreign currencies which fluctuates with changes in the exchange rates. Government bonds, short-term bills and notes are priced based on quoted market values. | ||||||||||||||||||||||||
Level 2 Measurements | ||||||||||||||||||||||||
Most U.S. Government Agency obligations, mortgage/asset-backed securities, and corporate fixed income securities are generally valued by benchmarking model-derived prices to quoted market prices and trade data for identical or comparable securities. To the extent that quoted prices are not available, fair value is determined based on a valuation model that includes inputs such as interest rate yield curves and credit spreads. Securities traded in markets that are not considered active are valued based on quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Other fixed income includes futures and options which are priced on bid valuation or settlement pricing. | ||||||||||||||||||||||||
Commingled funds that hold underlying investments that have prices which are derived from the quoted prices in active markets are classified as Level 2. The funds' underlying assets are principally marketable equity and fixed income securities. Units held in commingled funds are valued at the unit value as reported by the investment managers. The fair value of the investments in commingled funds has been estimated using the net asset value per share of the investments. | ||||||||||||||||||||||||
Level 3 Measurements | ||||||||||||||||||||||||
Commingled funds that hold underlying investments that have prices which are not derived from the quoted prices in active markets are classified as Level 3. The respective fair values of these investments are determined by reference to the funds' underlying assets, which are principally marketable equity and fixed income securities. Units held in commingled funds are valued at the unit value as reported by the investment managers. These investments are often valued by investment managers on a periodic basis using pricing models that use market, income, and cost valuation methods. | ||||||||||||||||||||||||
The hedge funds of funds invest in several strategies including fundamental long/short, relative value, and event driven. Hedge fund of fund investments may be redeemed annually, usually with 100 days' notice. Private equity investment strategies include buy-out, venture capital, growth equity, distressed debt, and mezzanine debt. Private equity investments are held through limited partnerships. | ||||||||||||||||||||||||
Limited partnerships are valued at estimated fair market value based on their proportionate share of the partnership's fair value as recorded in the partnerships' audited financial statements. Partnership interests represent ownership interests in private equity funds and real estate funds. Real estate partnerships invest in natural resources, commercial real estate and distressed real estate. The fair value of these investments is determined by reference to the funds' underlying assets, which are principally securities, private businesses, and real estate properties. The value of interests held in limited partnerships, other than securities, is determined by the general partner, based upon third-party appraisals of the underlying assets, which include inputs such as cost, operating results, discounted cash flows and market based comparable data. Private equity and real estate limited partnerships typically call capital over a 3 to 5 year period and pay out distributions as the underlying investments are liquidated. The typical expected life of these limited partnerships is 10-15 years and these investments typically cannot be redeemed prior to liquidation. | ||||||||||||||||||||||||
For the year ended December 31, 2013, there were no significant changes to valuation techniques to determine the fair value of NiSource's pension and other postretirement benefits' assets. | ||||||||||||||||||||||||

(1) The change in benefit obligation for Pension Benefits represents the change in Projected Benefit Obligation while the change in benefit obligation for Other Postretirement Benefits represents the change in Accumulated Postretirement Benefit Obligation. | ||||||||||||||||||||||||
(2) NiSource recognizes in its Consolidated Balance Sheets the underfunded and overfunded status of its various defined benefit postretirement plans, measured as the difference between the fair value of the plan assets and the benefit obligation. | ||||||||||||||||||||||||
(3) NiSource determined that for certain rate-regulated subsidiaries the future recovery of pension and other postretirement benefits costs is probable. These rate-regulated subsidiaries recorded regulatory assets and liabilities of $842.2 million and $49.4 million, respectively, as of December 31, 2013, and $1,345.7 million and $0.4 million, respectively, as of December 31, 2012 that would otherwise have been recorded to accumulated other comprehensive loss. | ||||||||||||||||||||||||
NiSource’s accumulated benefit obligation for its pension plans was $2,511.9 million and $2,771.6 million as of December 31, 2013 and 2012, respectively. The accumulated benefit obligation as of a date is the actuarial present value of benefits attributed by the pension benefit formula to employee service rendered prior to that date and based on current and past compensation levels. The accumulated benefit obligation differs from the projected benefit obligation disclosed in the table above in that it includes no assumptions about future compensation levels. | ||||||||||||||||||||||||
NiSource pension plans were underfunded by $260.9 million at December 31, 2013 compared to being underfunded at December 31, 2012 by $631.0 million. The improvement in the funded status was due primarily to favorable asset returns, an increase in discount rate from the prior measurement date and increased employer contributions. NiSource contributed $49.3 million and $3.7 million to its pension plans in 2013 and 2012, respectively. | ||||||||||||||||||||||||
NiSource’s funded status for its other postretirement benefit plans improved by $202.5 million to an underfunded status of $260.0 million primarily due to favorable asset returns, an increase in discount rate from the prior measurement date, a change in the retirement rate assumption and increased employer contributions. NiSource contributed approximately $54.3 million and $47.3 million to its other postretirement benefit plans in 2013 and 2012, respectively. No amounts of NiSource’s pension or other postretirement plans’ assets are expected to be returned to NiSource or any of its subsidiaries in 2014. | ||||||||||||||||||||||||
In 2013, NiSource pension plans had year to date lump sum payouts exceeding the plan's 2013 service cost plus interest cost and, therefore, settlement accounting was required. A settlement charge of $33.4 million was recorded in 2013. Net periodic pension benefit cost for 2013 was decreased by $3.6 million as a result of the interim remeasurements. | ||||||||||||||||||||||||
The following table provides the key assumptions that were used to calculate the pension and other postretirement benefits obligations for NiSource’s various plans as of December 31: | ||||||||||||||||||||||||

The increase of $9.5 million in net periodic benefit cost related to pension in 2013 compared to 2012 is due primarily to a higher settlement charge in 2013 compared to 2012 and decreasing interest rates, partially offset by favorable asset returns. For its other postretirement benefit plans, NiSource recognized $24.8 million in net periodic benefit cost in 2013 compared to $32.9 million in 2012 due primarily to favorable asset returns and claims experience partially offset by a decrease in the discount rate in 2013 compared to 2012. For 2013 and 2012, pension and other postretirement benefit cost of approximately $17.0 million and $25.1 million, respectively, was capitalized as a component of plant or recognized as a regulatory asset or liability consistent with regulatory orders for certain of NiSource’s regulated businesses. | ||||||||||||||||||||||||

Common Stock Dividend. Holders of shares of NiSource’s common stock are entitled to receive dividends when, as and if declared by the Board out of funds legally available. The policy of the Board has been to declare cash dividends on a quarterly basis payable on or about the 20th day of February, May, August and November. NiSource has paid quarterly common dividends totaling $0.98, $0.94 and $0.92 per share for the years ended December 31, 2013, 2012 and 2011, respectively.

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 1994 Plan or the Director Plan (described below) that expire or terminate for any reason. No further awards are permitted to be granted under the prior 1994 Plan or the Director Plan. At December 31, 2013, there were 6,733,397 shares reserved for future awards under the Omnibus Plan. | ||||||
Prior to May 11, 2010, NiSource issued long-term equity incentive grants to key management employees under a long-term incentive plan approved by stockholders on April 13, 1994 (“1994 Plan”). The types of equity awards previously authorized under the 1994 Plan did not significantly differ from those permitted under the Omnibus Plan. | ||||||
NiSource recognized stock-based employee compensation expense of $20.7 million, $17.8 million and $13.4 million during 2013, 2012 and 2011, respectively, as well as related tax benefits of $7.2 million, $6.1 million and $4.7 million, respectively. | ||||||
As of December 31, 2013, the total remaining unrecognized compensation cost related to nonvested awards amounted to $18.1 million, which will be amortized over the weighted-average remaining requisite service period of 1.8 years. | ||||||
Stock Options. Option grants may be awarded with an exercise price equal to the average of the high and low market price on the day of the grant. As of December 31, 2013, the weighted average remaining contractual life of the options outstanding and exercisable was 0.9 years. Stock option transactions for the year ended December 31, 2013 were as follows: | ||||||

No options were granted during the years ended December 31, 2013, 2012 and 2011. As of December 31, 2013, the aggregate intrinsic value for the options outstanding and exercisable was $4.2 million. During 2013, 2012, and 2011, cash received from the exercise of options was $25.4 million, $27.5 million, and $8.8 million, respectively. | ||||||
Restricted Stock Units and Restricted Stock. In 2013, NiSource granted restricted stock units and shares of restricted stock of 69,651, subject to service conditions. The total grant date fair value of the shares of restricted stock units and shares of restricted stock was $1.8 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 December 31, 2013, 69,651 nonvested (all of which are expected to vest) restricted stock units and shares of restricted stock were granted and outstanding for the 2013 award. | ||||||
In 2012, NiSource granted restricted stock units and shares of restricted stock of 226,431, subject to service conditions. The total grant date fair value of the restricted stock units and shares of restricted stock was $5.1 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of dividends not received during the vesting period, which will be expensed, net of forfeitures, over the vesting period which is generally three years. As of December 31, 2013, 184,576 nonvested (all of which are expected to vest) restricted stock units and shares of restricted stock were granted and outstanding for the 2012 award. | ||||||
In 2011, NiSource granted restricted stock units and shares of restricted stock of 142,593, subject to service conditions. The total grant date fair value of the restricted stock units and shares of restricted stock was $2.4 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of dividends not received during the vesting period, which will be expensed, net of forfeitures, over the vesting period which is generally three years. As of December 31, 2013, 101,009 nonvested (all of which are expected to vest) restricted stock units and shares of restricted stock were granted and outstanding for the 2011 award. | ||||||
If the employee terminates employment before the service conditions lapse under the 2011, 2012 and 2013 awards due to (1) Retirement or Disability (as defined in the award agreement), or (2) death, the service conditions will lapse on the date of such termination with respect to a pro rata portion of the restricted stock units and shares of restricted stock. In the event of a Change-in-Control (as defined in the award agreement), all unvested shares of restricted stock and restricted stock units will immediately vest. Termination due to any other reason will result in all restricted stock units and shares of restricted stock awarded being forfeited effective on the employee's date of termination. | ||||||

Performance Shares. In 2013, NiSource granted 664,776 performance shares subject to performance and service conditions. The grant date fair-value of the awards was $15.7 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of dividends not received during the vesting period which will be expensed, net of forfeitures, over the three year requisite service period. The performance conditions are based on achievement of certain non-GAAP financial measures: cumulative net operating earnings, that NiSource defines as income from continuing operations adjusted for certain items; and cumulative funds from operations that NiSource defines as net operating cash flows provided by continuing operations; and relative total shareholder return, a non-GAAP market measure that NiSource defines as the annualized growth in the dividends and share price of a share of NiSource’s common stock (calculated using a 20 trading day average of NiSource’s closing price beginning December 31, 2012 and ending on December 31, 2015) compared to the total shareholder return performance of a predetermined peer group of companies. The service conditions lapse on February 29, 2016 when the shares vest provided the performance criteria are satisfied. As of December 31, 2013, 647,795 nonvested performance shares were granted and outstanding of the 2013 award. | ||||||
In 2012, NiSource granted 772,128 performance shares subject to performance and service conditions. The grant date fair-value of the awards was $16.0 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of dividends not received during the vesting period which will be expensed, net of forfeitures, over the three year requisite service period. The performance conditions are based on achievement of certain non-GAAP financial measures: cumulative net operating earnings, that NiSource defines as income from continuing operations adjusted for certain items; and cumulative funds from operations that NiSource defines as net operating cash flows provided by continuing operations; and relative total shareholder return, a non-GAAP market measure that NiSource defines as the annualized growth in the dividends and share price of a share of NiSource’s common stock (calculated using a 20 trading day average of NiSource’s closing price beginning December 31, 2011 and ending on December 31, 2014) compared to the total shareholder return performance of a predetermined peer group of companies. The service conditions lapse on January 30, 2015 when the shares vest provided the performance criteria are satisfied. As of December 31, 2013, 711,581 nonvested performance shares were granted and outstanding of the 2012 award. | ||||||
In 2011, NiSource granted 749,237 performance shares subject to performance and service conditions. The grant date fair-value of the awards was $12.0 million, based on the average market price of NiSource’s common stock at the date of each grant less the present value of dividends not received during the vesting period which will be expensed, net of forfeitures, over the three year requisite service period. The performance conditions are based on achievement of non-GAAP financial measures: cumulative net operating earnings, that NiSource defines as income from continuing operations adjusted for certain items; cumulative funds from operations that NiSource defines as net operating cash flows provided by continuing operations; and total debt that NiSource defines as total debt adjusted for significant movement in natural gas prices and other adjustments determined by the Board. The service conditions lapse on January 31, 2014 when the shares vest provided the performance criteria are satisfied. As of December 31, 2013, 614,961 nonvested performance shares were granted and outstanding for the 2011 award. | ||||||
If the employee terminates employment before the service conditions lapse under the 2011, 2012 and 2013 awards due to (1) Retirement or Disability (as defined in the award agreement), or (2) death, the service conditions will lapse on the date of such termination with respect to a pro rata portion of the performance shares. In the event of a Change-in-Control (as defined in the award agreement), all unvested performance shares will immediately vest. Termination due to any other reason will result in all performance shares awarded being forfeited effective on the employee's date of termination. | ||||||

Non-employee Director Awards. As of May 11, 2010, awards to non-employee directors may be made only under the Omnibus Plan. Currently, restricted stock units are granted annually to non-employee directors, subject to a non-employee director’s election to defer receipt of such restricted stock unit award. The non-employee director’s restricted stock units vest on the last day of the non-employee director’s annual term corresponding to the year the restricted stock units were awarded subject to special pro-rata vesting rules in the event of Retirement or Disability (as defined in the award agreement), or death. The vested restricted stock units are payable as soon as practicable following vesting except as otherwise provided pursuant to the non-employee director’s election to defer. As of December 31, 2013, 142,522 restricted stock units are outstanding to non-employee directors under the Omnibus Plan. | ||||||
Only restricted stock units remain outstanding under the prior plan for non-employee directors, the Amended and Restated Non-employee Director Stock Incentive Plan (the “Director Plan”). All such awards are fully vested and shall be distributed to the directors upon their separation from the Board. As of December 31, 2013, 147,845 restricted stock units remain outstanding under the Director Plan and as noted above no further shares may be awarded under the Director Plan. | ||||||
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 in newly issued shares of common stock. NiSource also has a retirement savings plan that provides for discretionary profit sharing contributions of 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 in shares of common stock. For the years ended December 31, 2013, 2012 and 2011, NiSource recognized 401(k) match, profit sharing and non-elective contribution expense of $30.0 million, $27.3 million and $25.9 million, respectively. |

Long-Term Debt | ' | |||
Long-Term Debt | ||||
NiSource Finance is a 100% owned, consolidated finance subsidiary of NiSource that engages in financing activities to raise funds for the business operations of NiSource and its subsidiaries. NiSource Finance was incorporated in March 2000 under the laws of the state of Indiana. Prior to 2000, the function of NiSource Finance was performed by Capital Markets. NiSource Finance obligations are fully and unconditionally guaranteed by NiSource. Consequently no separate financial statements for NiSource Finance are required to be reported. No other NiSource subsidiaries guarantee debt. | ||||
During 2013, NiSource Finance issued $1.3 billion of long-term debt securities, increased its term loan borrowings by $75.0 million and redeemed $420.3 million of long-term debt securities, while NIPSCO redeemed a total of $68.0 million of medium-term notes and pollution control bonds. These transactions are detailed as follows: | ||||
• | On October 10, 2013, NiSource Finance issued $500.0 million of 5.65% senior unsecured notes that mature on February 1, 2045. | |||
• | On August 19, 2013, NIPSCO redeemed $30.0 million of 7.16% medium term notes. | |||
• | On July 22, 2013, NIPSCO redeemed $5.0 million of 7.21% medium term notes. | |||
• | On July 8, 2013, NIPSCO redeemed $15.0 million of 7.35% medium term notes. | |||
• | On June 3, 2013, NIPSCO redeemed $18.0 million of 5.20% pollution control bonds. | |||
• | On April 15, 2013, NiSource Finance amended the term loan to add an additional lender to the syndicate of banks, increase borrowings under the term loan by $75.0 million to a total of $325.0 million and extend the maturity date to April 15, 2016. Borrowings under the term loan carried an interest rate of BBA LIBOR plus 125 basis points during 2013. Effective with Moody's credit rating upgrade on January 31, 2014, NiSource's credit spread on the term loan is 100 basis points. | |||
• | On April 12, 2013, NiSource Finance issued $750.0 million of 4.80% senior unsecured notes that mature on February 15, 2044. | |||
• | On March 1, 2013, NiSource Finance redeemed $420.3 million of 6.15% senior unsecured notes. | |||
During 2012, NiSource Finance issued $750.0 million of long-term debt securities, negotiated a term loan for $250.0 million, and redeemed $315.0 million of long-term debt securities. These transactions are detailed as follows: | ||||
• | On November 28, 2012, NiSource Finance redeemed $315.0 million of 5.21% private placement notes. | |||
• | On June 14, 2012, NiSource Finance issued $250.0 million of 3.85% senior unsecured notes that mature on February 15, 2023 and $500.0 million of 5.25% senior unsecured notes that mature on February 15, 2043. | |||
• | On April 5, 2012, NiSource Finance negotiated a $250.0 million three-year bank term loan with a syndicate of banks carrying an interest rate of BBA LIBOR plus 125 basis points during 2012. On April 15, 2013, NiSource Finance amended the term loan as described above. | |||
During 2011, NiSource Finance issued $900.0 million of long-term notes and redeemed $250.0 million of long-term notes while NIPSCO redeemed $18.7 million of medium term notes. These transactions are detailed as follows: | ||||
• | On November 23, 2011, NiSource Finance issued $250.0 million of 4.45% senior unsecured notes that mature December 1, 2021 and $250.0 million of 5.80% senior unsecured notes that mature February 1, 2042. | |||
• | On November 14, 2011, NiSource Finance commenced a cash tender offer for up to $250.0 million aggregate principal amount of its outstanding 10.75% notes due 2016 and 6.15% notes due 2013. A condition of the offering was that all validly tendered 2016 notes would be accepted for purchase before any 2013 notes were accepted. On December 13, 2011, NiSource Finance announced that approximately $125.3 million of the aggregate principal amount of its outstanding 10.75% notes due 2016 were validly tendered and accepted for purchase. In addition, approximately $228.7 million of the aggregate principal amount of outstanding 6.15% notes due 2013 were validly tendered, of which $124.7 million were accepted for purchase. In accordance with the provisions of ASC 470, Debt, NiSource Finance determined the debt issued on November 23, 2011 was substantially different from the tendered notes, and therefore the transaction qualified as a debt extinguishment. NiSource Finance recorded a $53.9 million loss on early extinguishment of long-term debt, primarily attributable to early redemption premiums and unamortized discounts and fees. | |||
• | During July 2011, NIPSCO redeemed $18.7 million of its medium-term notes, with an average interest rate of 7.30%. | |||
• | On June 10, 2011, NiSource Finance issued $400.0 million of 5.95% senior unsecured notes that mature June 15, 2041. | |||
In the following table are the outstanding long-term debt sinking fund requirements and maturities at December 31, 2013. The long-term debt maturities shown below include capital lease obligations and the debt of certain low-income housing real estate investments. NiSource does not guarantee the long-term debt obligations of the low-income housing real estate investments. | ||||

Unamortized debt expense, premium and discount on long-term debt applicable to outstanding bonds are being amortized over the life of such bonds. Reacquisition premiums have been deferred and are being amortized. These premiums are not earning a regulatory return during the recovery period. | ||||
Of NiSource’s long-term debt outstanding at December 31, 2013, $109.0 million was issued by NiSource’s subsidiary, Capital Markets. The financial obligations of Capital Markets are subject to a Support Agreement between NiSource and Capital Markets, under which NiSource has committed to make payments of interest and principal on Capital Markets’ obligations in the event of a failure to pay by Capital Markets. Under the terms of the Support Agreement, in addition to the cash flow from cash dividends paid to NiSource by any of its consolidated subsidiaries, the assets of NiSource, other than the stock and assets of NIPSCO, are available as recourse for the benefit of Capital Markets’ creditors. The carrying value of the NiSource assets, excluding the assets of NIPSCO, was $16.6 billion at December 31, 2013. | ||||
NiSource Finance maintains $500.0 million notional value of interest rate swap agreements relating to its outstanding long-term debt. The effect of these agreements is to modify the interest rate characteristics of a portion of its long-term debt from fixed to variable. Refer to Note 9, “Risk Management Activities,” in the Notes to Consolidated Financial Statements for further information regarding interest rate swaps. | ||||
NiSource is subject to a financial covenant under its revolving credit facility and its term loan which requires NiSource to maintain a debt to capitalization ratio that does not exceed 70%. A similar covenant in a 2005 private placement note purchase agreement requires NiSource to maintain a debt to capitalization ratio that does not exceed 75%. As of December 31, 2013, the ratio was 60%. | ||||
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. |

On September 30, 2013, NiSource Finance amended its existing revolving credit facility with a syndicate of banks led by Barclays Capital to expand its borrowing capacity to $2.0 billion and extend the termination date to 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 December 31, 2013, NiSource had no outstanding borrowings under this facility. | ||||||||
During June 2011, NiSource Finance implemented a new commercial paper program with a program limit of up to $500.0 million with a dealer group comprised of Barclays, Citigroup, Credit Suisse and Wells Fargo. The program capacity was expanded to $1.5 billion with the addition of RBS as a fifth dealer on February 15, 2013. Commercial paper issuances are supported by available capacity under NiSource’s $2.0 billion unsecured revolving credit facility. At December 31, 2013, NiSource had $433.6 million of commercial paper outstanding. | ||||||||
As of December 31, 2013 and 2012, NiSource had $31.6 million and $36.4 million, respectively, of stand-by letters of credit outstanding, of which $14.3 million and $18.3 million, respectively, were under the revolving credit facility. | ||||||||
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term debt on the Consolidated Balance Sheets in the amount of $265.1 million and $233.3 million as of December 31, 2013 and 2012, respectively.

Price risk management assets and liabilities include 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 December 31, 2013 and 2012, 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. | ||||||||||||||||
To determine the fair value of derivatives associated with NiSource’s unregulated natural gas marketing business, certain reserves were calculated. These reserves were primarily determined by evaluating the credit worthiness of certain customers, fair value of future cash flows, and the cost of maintaining restricted cash. Refer to Note 9, “Risk Management Activities” for additional information on price risk assets. | ||||||||||||||||
Price risk management assets also include fixed-to-floating interest-rate swaps, which are designated as fair value hedges, as a means to achieve NiSource’s targeted level of variable-rate debt as a percent of total debt. NiSource uses a calculation of future cash inflows and estimated future outflows related to the swap agreements, which are discounted and netted to determine the current fair value. Additional inputs to the present value calculation include the contract terms, as well as market parameters such as current and projected interest rates and volatility. As they are based on observable data and valuations of similar instruments, the interest-rate swaps are categorized in Level 2 in the fair value hierarchy. Credit risk is considered in the fair value calculation of the interest rate swap. | ||||||||||||||||
Available-for-sale securities are investments pledged as collateral for trust accounts related to NiSource’s wholly-owned insurance company. Available-for-sale securities are included within “Other investments” in the Consolidated Balance Sheets. 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 gains and losses from available-for-sale securities are included in accumulated other comprehensive income (loss). The amortized cost, gross unrealized gains and losses, and fair value of available-for-sale debt securities at December 31, 2013 and December 31, 2012 were: | ||||||||||||||||

For the year ended December 31, 2013, 2012, and 2011 the realized gain on sale of available for sale U.S. Treasury debt securities was $0.5 million, $0.6 million and $0.5 million, respectively. For the year ended December 31, 2013, 2012, and 2011 the realized gain on sale of available for sale Corporate/Other bond debt securities was $0.4 million, $0.3 million, and $0.9 million. | ||||||||||||||||
The cost of maturities sold is based upon specific identification. At December 31, 2013, approximately $3.1 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 December 31, 2013 approximately $3.2 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 years ended December 31, 2013 and 2012. | ||||||||||||||||
Non-recurring Fair Value Measurements. In January 2013, NiSource sold the service plan and leasing business lines of its Retail Services business. The disposed business lines were included in the Columbia Distribution Operations reporting unit and the NIPSCO Gas Distribution Operations reporting unit. Goodwill associated with the disposed business lines was included in the carrying amount of the business lines in determining the gain on disposal. The amount of the goodwill included in the carrying amount was based on the relative fair values of the business lines disposed of and the portion of the reporting units that were retained. The fair value of the disposed business lines was determined by using the selling price of the business lines. The fair value of the reporting units that were retained was determined by a weighted average of income and market approaches. This approach was similar to the process undertaken to calculate the fair value of the reporting units for the goodwill impairment test conducted on May 1, 2012. These approaches are further discussed in Note 6, "Goodwill and Other Intangible Assets" and yield fair values considered to be at Level 3 of the fair value hierarchy. The respective fair value of the disposed business lines was divided by the fair value of the reporting units to which the disposed business lines belonged. These percentages were then applied to those goodwill balances to determine their allocations. As a result of these procedures, NiSource recorded a disposal of goodwill of approximately $11.0 million during the first quarter of 2013. This amount is included within the "Gain on Disposition of Discontinued Operations - net of taxes" on the Statements of Consolidated Income. | ||||||||||||||||
There were no significant non-recurring fair value measurements recorded during the twelve months ended December 31, 2012. | ||||||||||||||||
B.Other Fair Value Disclosures for Financial Instruments. NiSource has certain financial instruments that are not measured at fair value on a recurring basis but nevertheless are recorded at amounts that approximate fair value due to their liquid or short-term nature, including cash and cash equivalents, restricted cash, notes receivable, customer deposits and short-term borrowings. NiSource’s long-term borrowings are recorded at historical amounts unless designated as a hedged item in a fair value hedge. | ||||||||||||||||
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 years ended December 31, 2013 and 2012, there were no changes in the method or significant assumptions used to estimate the fair value of the financial instruments. | ||||||||||||||||
The carrying amount and estimated fair values of financial instruments were as follows: | ||||||||||||||||

Transfers of Financial Assets | ||||||||
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term borrowings on the Consolidated Balance Sheets. 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 commercial paper conduits 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. | ||||||||
Throughout 2013 and 2012, Columbia of Ohio has been 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, first entered into on October 19, 2012, and subsequently renewed on October 18, 2013, 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. Prior to this agreement with BTMU and BNS, CGORC was party to a series of agreements with BTMU and RBS. The maximum seasonal program limit under the terms of the new agreement remains at $240 million. The current agreement expires on October 17, 2014, and can be further renewed if mutually agreed to by all parties. As of December 31, 2013, $105.1 million of 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. | ||||||||
Throughout 2013 and 2012, NIPSCO has been 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 first entered into on August 29, 2012, and subsequently renewed on August 28, 2013, under the terms of which it sells an undivided percentage ownership interest in its accounts receivable to commercial paper conduits sponsored by PNC and Mizuho. Prior to this agreement with PNC and Mizuho, NARC was party to a series of agreements with RBS. The maximum seasonal program limit under the terms of the new agreement remains at $200 million. The current agreement expires on August 27, 2014, and can be further renewed if mutually agreed to by all parties. As of December 31, 2013, $125.0 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. | ||||||||
Throughout 2013 and 2012, Columbia of Pennsylvania has been 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 maximum seasonal program limit under the terms of the agreement is $75 million. The agreement with BTMU was renewed on March 13, 2013, having a current scheduled termination date of March 11, 2014, which can be further renewed if mutually agreed to by both parties. As of December 31, 2013, $35.0 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. | ||||||||
The following table reflects the gross and net receivables transferred as well as short-term borrowings related to the securitization transactions as of December 31, 2013 and 2012 for Columbia of Ohio, NIPSCO and Columbia of Pennsylvania: | ||||||||

Short-term debt due to asset securitization | $ | 265.1 | $ | 233.3 | ||||
During 2013 and 2012, $31.8 million and $1.6 million was recorded as cash from financing activities related to the change in short-term borrowings due to the securitization transactions, respectively. For the years ended December 31, 2013 and 2012, fees of $2.7 million and $3.5 million associated with the securitization transactions were recorded as interest expense, respectively. Columbia of Ohio, NIPSCO and Columbia of Pennsylvania remain responsible for collecting on the receivables securitized and the receivables cannot be sold to another party. |

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 December 31, 2013 and the years in which they expire are: | ||||||||||||||||||||||||||||

Guarantees of Subsidiaries Debt. NiSource has guaranteed the payment of $7.7 billion 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 Consolidated Balance Sheets. 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 medium-term notes. | ||||||||||||||||||||||||||||
Lines and Letters of Credit and Accounts Receivable Advances. On September 30, 2013, NiSource Finance amended its existing revolving credit facility with a syndicate of banks led by Barclays Capital to expand capacity to $2.0 billion and extend the termination date to 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 December 31, 2013, NiSource had no borrowings under its five-year revolving credit facility, $433.6 million in commercial paper outstanding and $265.1 million outstanding under its accounts receivable securitization agreements. At December 31, 2013, NiSource issued stand-by letters of credit of approximately $31.6 million for the benefit of third parties. See Note 17, “Short-Term Borrowings,” for additional information. | ||||||||||||||||||||||||||||
Other Guarantees or Obligations. NiSource has purchase and sale agreement guarantees totaling $73.5 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 Consolidated Balance Sheets. 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 issued other guarantees supporting derivative related payments associated with interest rate swap agreements issued by NiSource Finance, operating leases for many of its subsidiaries and for other agreements entered into by its current and former subsidiaries. | ||||||||||||||||||||||||||||
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.Tax Matters. NiSource records liabilities for potential income tax assessments. The accruals relate to tax positions in a variety of taxing jurisdictions and are based on management’s estimate of the ultimate resolution of these positions. These liabilities may be affected by changing interpretations of laws, rulings by tax authorities, or the expiration of the statute of limitations. NiSource is part of the IRS Large and Mid-Size Business program. As a result, each year’s federal income tax return is typically audited by the IRS. As of December 31, 2013, tax years through 2010 have been audited and are effectively closed to further assessment. The audits of tax years 2011, 2012 and 2013 under the Compliance Assurance Program ("CAP") are in process. As of December 31, 2013, there were no state income tax audits in progress that would have a material impact on the consolidated financial statements. | ||||||||||||||||||||||||||||
NiSource is currently being audited for sales and use tax compliance in the states of Louisiana, Pennsylvania, and Massachusetts. | ||||||||||||||||||||||||||||
D.Environmental Matters. NiSource operations are subject to environmental statutes and regulations related to air quality, water quality, hazardous waste and solid waste. NiSource believes that it is in substantial compliance with 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 December 31, 2013 and 2012, NiSource had recorded reserves of approximately $143.9 million and $160.6 million, respectively, to cover environmental remediation at various sites. The current portion of this reserve is included in Legal and Environmental Reserves in the Consolidated Balance Sheets. The noncurrent portion is included in Other noncurrent liabilities in the Consolidated Balance Sheets. 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 reserves 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. | ||||||||||||||||||||||||||||
In the first quarter of 2012, the EPA proposed an output-based carbon standard for new power plants. On September 20, 2013, the EPA announced withdrawal of the proposed standard and released a new proposal. The newly proposed standard would, for the first time, set national limits on the amount of carbon emissions allowed from new power plants. The revised numerical limit requires that compliance for new coal-fired plants may need to include capture and sequestration of carbon dioxide. In addition, the EPA stated that it intends to regulate existing sources with a proposed rule expected in 2014. | ||||||||||||||||||||||||||||
If the EPA develops a GHG new source performance standard for existing units or if a federal or state comprehensive climate change bill were to be enacted into law, the impact on NiSource's financial performance would depend on a number of factors, including the overall level of required GHG reductions, the degree to which offsets may be used for compliance, and the amount of recovery allowed from customers. Comprehensive federal or state GHG regulation could result in additional expense or compliance costs that may not be fully recoverable from customers and could materially impact NiSource’s financial results. | ||||||||||||||||||||||||||||
National Ambient Air Quality Standards. The CAA requires the EPA to set national air quality standards (the 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: | ||||||||||||||||||||||||||||
Particulate Matter: In December 2009, the EPA issued area designations for the 2006 24-hour PM2.5 standard, and several counties in which NiSource operates were designated as non-attainment. In addition, a final rule was promulgated in December 2012 that lowered the annual PM2.5 standard from 15 to 12 µg/m3. NiSource will continue to monitor these matters and cannot estimate their impact at this time. | ||||||||||||||||||||||||||||
Ozone (eight hour): On September 2, 2011, the EPA announced it would implement its 2008 eight-hour ozone NAAQS rather than tightening the standard in 2012. The EPA will review, and possibly revise, the standard in 2014. In addition, the EPA has designated the Chicago metropolitan area, including the area in which NIPSCO operates one of its electric generation facilities, as non-attainment for ozone. NiSource will continue to monitor this matter and cannot estimate the impact of any new rules 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, 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 67 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 liability were noted as a result of the refresh completed as of June 30, 2013. The total liability at NiSource related to the facilities subject to remediation was $129.5 million and $132.6 million at December 31, 2013 and 2012, 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 Columbia Pipeline Group Operations, Electric Operations, and certain other discontinued operations for which NiSource has retained a liability. | ||||||||||||||||||||||||||||
Columbia Pipeline Group Operations. | ||||||||||||||||||||||||||||
Waste | ||||||||||||||||||||||||||||
Columbia Transmission continues to conduct characterization and remediation activities at specific sites under a 1995 AOC (subsequently modified in 1996 and 2007). The 1995 AOC originally covered 245 major facilities, approximately 13,000 liquid removal points, approximately 2,200 mercury measurement stations and about 3,700 storage well locations. As a result of the 2007 amendment, approximately 50 facilities remain subject to the terms of the AOC. NiSource utilizes a probabilistic model to estimate its future remediation costs related to the 1995 AOC. The model was prepared with the assistance of a third party and incorporates NiSource and general industry experience with remediating sites. NiSource completes an annual refresh of the model in the second quarter of each fiscal year. No material changes to the liability were noted as a result of the refresh completed as of June 30, 2013. The total liability at Columbia Transmission related to the facilities subject to remediation was $8.7 million and $21.7 million at December 31, 2013 and December 31, 2012, respectively. The liability represents Columbia Transmission's best estimate of the cost to remediate the facilities or manage the sites. Remediation costs are estimated based on the information available, applicable remediation standards, and experience with similar facilities. Columbia Transmission expects that the remediation for these facilities will be substantially completed in 2015. | ||||||||||||||||||||||||||||
Electric Operations. | ||||||||||||||||||||||||||||
Air | ||||||||||||||||||||||||||||
NIPSCO expects to become subject to a number of new air-quality mandates in the next several years. These mandates may require NIPSCO to make capital improvements to its electric generating stations. The cost of capital improvements is estimated to be $860 million, of which approximately $277.0 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 ratepayers. | ||||||||||||||||||||||||||||
Cross-State Air Pollution Rule / Clean Air Interstate Rule (CAIR) / Transport Rule: On July 6, 2011, the EPA announced its replacement for the 2005 CAIR to reduce the interstate transport of fine particulate matter and ozone. The CSAPR reduces overall emissions of SO2 and NOx by setting state-wide caps on power plant emissions. The CSAPR limits emissions, including NIPSCO's, and restricted emission allowance trading programs were scheduled to begin in 2012. In a decision issued on August 21, 2012 the D.C. Circuit Court vacated the CSAPR leaving the CAIR trading program provisions and requirements in place. The EPA subsequently petitioned for a writ of certiorari, and the United States Supreme Court granted this writ. Oral arguments were held on December 10, 2013, before the United States Supreme Court and a decision is expected in 2014. These developments do not significantly impact NIPSCO's current emissions control plans. NIPSCO utilizes the inventory model in accounting for emission allowances issued under the CAIR program whereby these allowances were recognized at zero cost upon receipt from the EPA. NIPSCO believes its current multi-pollutant compliance plan and New Source Review Consent Decree capital investments will allow NIPSCO to meet the emission requirements of CAIR, while a replacement for CSAPR is developed to address the court's decision. | ||||||||||||||||||||||||||||
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. Compliance for NIPSCO’s affected units is required by April 2016. NIPSCO developed and obtained IURC approval of a plan for environmental controls to comply with MATS. | ||||||||||||||||||||||||||||
New Source Review: On September 29, 2004, the EPA issued an NOV to NIPSCO for alleged violations of the CAA and the Indiana SIP. The NOV alleged that modifications were made to certain boiler units at three of NIPSCO's generating stations between the years 1985 and 1995 without obtaining appropriate air permits for the modifications. NIPSCO, the EPA, the Department of Justice, and IDEM have settled the matter through a consent decree, entered on July 22, 2011. | ||||||||||||||||||||||||||||
Water | ||||||||||||||||||||||||||||
The 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, became effective on September 7, 2004. Under this rule, stations will either have to 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. Various court challenges and EPA responses ensued. A final rule is expected to be issued in early 2014. NIPSCO will continue to monitor this matter but 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 June 21, 2010, the EPA published a proposed rule for regulation of CCRs. The proposal outlines multiple regulatory approaches that the EPA is considering. These proposed regulations could negatively affect NIPSCO’s ongoing byproduct reuse programs and would impose additional requirements on its management of coal combustion residuals. NIPSCO will continue to monitor developments in this matter and cannot estimate the cost of compliance at this time. | ||||||||||||||||||||||||||||
Other Operations. | ||||||||||||||||||||||||||||
Waste | ||||||||||||||||||||||||||||
NiSource affiliates have retained environmental liabilities, including cleanup liabilities associated with some of its former operations. Four sites are associated with its former propane operations and ten sites associated with former petroleum operations. At one of those sites, an AOC has been signed with the EPA to address petroleum residue in soil and groundwater. NiSource will continue to monitor developments in this matter and cannot estimate the cost of compliance at this time. | ||||||||||||||||||||||||||||
E.Operating and Capital Lease Commitments. NiSource leases assets in several areas of its operations. Payments made in connection with operating leases were $56.3 million in 2013, $50.9 million in 2012 and $52.9 million in 2011, and are primarily charged to operation and maintenance expense as incurred. Capital leases and related accumulated depreciation included in the Consolidated Balance Sheets were $208.2 million and $64.1 million at December 31, 2013, and $182.5 million and $46.8 million at December 31, 2012, respectively. | ||||||||||||||||||||||||||||
NiSource Corporate Services has a license agreement with Rational Systems, LLC for pipeline business software requiring payments of $5.8 million and $25.6 million in 2014 and 2015, respectively, which are recorded as a capital lease. | ||||||||||||||||||||||||||||
NIPSCO has a service agreement with Pure Air, a general partnership between Air Products and Chemicals, Inc. and First Air Partners LP, under which Pure Air provides scrubber services to reduce sulfur dioxide emissions for Units 7 and 8 at the Bailly Generating Station. Services under this contract commenced on July 1, 1992 and expired on June 30, 2012. The agreement was renewed effective July 1, 2012 for ten years and NIPSCO will continue to pay for the services under a combination of fixed and variable charges. In accordance with GAAP, the renewed agreement was evaluated to determine whether the arrangement qualified as a lease. Based on the terms of the agreement, the arrangement qualified for capital lease accounting. As the effective date of the new agreement was July 1, 2012, NiSource capitalized this lease beginning in the third quarter of 2012. | ||||||||||||||||||||||||||||
Future minimum rental payments required under operating and capital leases that have initial or remaining non-cancelable lease terms in excess of one year are: | ||||||||||||||||||||||||||||

Total future minimum payments | $ | 75.4 | $ | 279.6 | ||||||||||||||||||||||||
(1) Operating lease balances do not include amounts for fleet leases that can be renewed beyond the initial lease term. The Company anticipates renewing the leases beyond the initial term, but the anticipated payments associated with the renewals do not meet the definition of expected minimum lease payments and therefore are not included above. Expected payments are $26.6 million in 2014, $29.5 million in 2015, $25.5 million in 2016, $20.4 million in 2017, $14.6 million in 2018 and $11.8 million thereafter. | ||||||||||||||||||||||||||||
(2) Capital lease payments shown above are inclusive of interest totaling $100.4 million. Also included are minimum lease payments for an office building that the Company will not occupy until 2014. | ||||||||||||||||||||||||||||
F.Purchase and Service Obligations. NiSource has entered into various purchase and service agreements whereby NiSource is contractually obligated to make certain minimum payments in future periods. NiSource’s purchase obligations are for the purchase of physical quantities of natural gas, electricity and coal. NiSource’s service agreements encompass a broad range of business support and maintenance functions which are generally described below. | ||||||||||||||||||||||||||||
NiSource’s subsidiaries have entered into various energy commodity contracts to purchase physical quantities of natural gas, electricity and coal. These amounts represent minimum quantities of these commodities NiSource is obligated to purchase at both fixed and variable prices. | ||||||||||||||||||||||||||||
In July 2008, the IURC issued an order approving NIPSCO’s proposed purchase power agreements with subsidiaries of Iberdrola Renewables, Buffalo Ridge I LLC and Barton Windpower LLC. These agreements provided NIPSCO the opportunity and obligation to purchase up to 100 mw of wind power generated commencing in early 2009. The contracts extend 15 and 20 years, representing 50 mw of wind power each. No minimum quantities are specified within these agreements due to the variability of electricity generation from wind, so no amounts related to these contracts are included in the table below. Upon any termination of the agreements by NIPSCO for any reason (other than material breach by Buffalo Ridge I LLC or Barton Windpower LLC), NIPSCO may be required to pay a termination charge that could be material depending on the events giving rise to termination and the timing of the termination. | ||||||||||||||||||||||||||||
NiSource has pipeline service agreements that provide for pipeline capacity, transportation and storage services. These agreements, which have expiration dates ranging from 2014 to 2024, require NiSource to pay fixed monthly charges. | ||||||||||||||||||||||||||||
On December 31, 2013, NiSource Corporate Services signed a seven year agreement with IBM to continue to provide business process and support functions to NiSource under a combination of fixed or variable charges, with the variable charges fluctuating based on the actual need for such services. The agreement is effective January 1, 2014 with a commencement date of April 1, 2014 and will include some targeted service enhancements as well as continue existing IT support services and a few additional support services. Under the existing and new agreements, at December 31, 2013, NiSource Corporate Services expects to pay approximately $665.4 million to IBM in service and project fees as shown in the table below. Upon any termination of the agreement by NiSource for any reason (other than material breach by IBM), NiSource may be required to pay IBM a termination charge that could include a breakage fee, repayment of IBM's capital investments not yet recovered and IBM's wind-down expense. This termination fee could be material depending on the events giving rise to the termination and the timing of the termination. | ||||||||||||||||||||||||||||
NiSource Corporate Services signed a service agreement with Vertex Outsourcing LLC, a business process outsourcing company, to provide customer contact center services for NiSource subsidiaries through June 2015.

Equity Method Investment | ||||||||||||||||
During 2008, Millennium, in which Columbia Transmission has an equity investment, entered into three interest rate swap agreements with a notional amount totaling $420.0 million with seven counterparties. During August 2010, Millennium completed the refinancing of its long-term debt, securing permanent fixed-rate financing through the private placement issuance of two tranches of notes totaling $725.0 million, $375.0 million at 5.33% due June 30, 2027 and $350.0 million at 6.00% due June 30, 2032. Upon the issuance of these notes, Millennium repaid all outstanding borrowings under its credit agreement, terminated the sponsor guarantee, and cash settled the interest rate hedges. These interest rate swap derivatives were primarily accounted for as cash flow hedges by Millennium. As an equity method investment, NiSource is required to recognize a proportional share of Millennium’s OCI. The remaining unrecognized loss of $17.7 million, net of tax, related to these terminated interest rate swaps is being amortized over a 15 year period ending June 2025 into earnings using the effective interest method through interest expense as interest payments are made by Millennium. The unrecognized loss of $17.7 million and $18.7 million at December 31, 2013 and December 31, 2012, respectively, is included in unrealized losses on cash flow hedges above. |

Segments of Business | ||||||||||||
Operating segments are components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance. The NiSource Chief Executive Officer is the chief operating decision maker. | ||||||||||||
At December 31, 2013, NiSource’s operations are divided into three primary business segments. The Gas Distribution Operations segment provides natural gas service and transportation for residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, Maryland, Indiana and Massachusetts. The Columbia Pipeline Group Operations segment offers gas transportation and storage services for LDCs, marketers and industrial and commercial customers located in northeastern, mid-Atlantic, midwestern and southern states and the District of Columbia along with unregulated businesses that include midstream services and development of mineral rights positions. The Electric Operations segment provides electric service in 20 counties in the northern part of Indiana. | ||||||||||||
The following table provides information about business segments. NiSource uses operating income as its primary measurement for each of the reported segments and makes decisions on finance, dividends and taxes at the corporate level on a consolidated basis. Segment revenues include intersegment sales to affiliated subsidiaries, which are eliminated in consolidation. Affiliated sales are recognized on the basis of prevailing market, regulated prices or at levels provided for under contractual agreements. Operating income is derived from revenues and expenses directly associated with each segment. | ||||||||||||

Organization, Consolidation and Presentation of Financial Statements [Abstract] | ' | ||||||||
Company Structure And Principles Of Consolidation | ' | ||||||||
Company Structure and Principles of Consolidation. NiSource, a Delaware corporation, is a holding company whose subsidiaries provide natural gas, electricity and other products and services to approximately 3.8 million customers located within a corridor that runs from the Gulf Coast through the Midwest to New England. NiSource derives substantially all of its revenues and earnings from the operating results of its thirteen direct subsidiaries. | |||||||||
The consolidated financial statements include the accounts of NiSource and its majority-owned subsidiaries after the elimination of all intercompany accounts and transactions. Investments for which at least a 20% interest is owned, certain joint ventures and limited partnership interests of more than 3% are accounted for under the equity method. Except where noted above and in the event where NiSource has significant influence, investments with less than a 20% interest are accounted for under the cost method. NiSource also consolidates variable interest entities for which NiSource is the primary beneficiary. | |||||||||
Use Of Estimates | ' | ||||||||
Use of Estimates. The preparation of financial statements in conformity with GAAP in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. | |||||||||
Cash, Cash Equivalents, And Restricted Cash | ' | ||||||||
Cash, Cash Equivalents, and Restricted Cash. NiSource considers all investments with original maturities of three months or less to be cash equivalents. NiSource reports amounts deposited in brokerage accounts for margin requirements as restricted cash. In addition, NiSource has amounts deposited in trust to satisfy requirements for the provision of various property, liability, workers compensation, and long-term disability insurance, which is classified as restricted cash and disclosed as an investing cash flow on the Statements of Consolidated Cash Flows. | |||||||||
Restricted cash was $8.0 million and $46.8 million as of December 31, 2013, and 2012, respectively. The decrease in restricted cash was primarily a result of the sale of NiSource’s unregulated natural gas marketing business. | |||||||||
Accounts Receivable And Unbilled Revenue | ' | ||||||||
Accounts Receivable and Unbilled Revenue. Accounts receivable on the Consolidated Balance Sheets includes both billed and unbilled amounts as NiSource believes that total accounts receivable is a more meaningful presentation, given the factors which impact both billed and unbilled accounts receivable. Unbilled revenue is based on estimated amounts of electric energy or natural gas delivered but not yet billed to its customers. Unbilled amounts of accounts receivable relate to a portion of a customer’s consumption of gas or electricity from the date of the last cycle billing date through the last day of the month (balance sheet date). Factors taken into consideration when estimating unbilled revenue include historical usage, customer rates and weather. Accounts receivable fluctuates from year to year depending in large part on weather impacts and price volatility. NiSource’s accounts receivable on the Consolidated Balance Sheets includes unbilled revenue, less reserves, in the amounts of $321.5 million and $285.7 million for the years ended December 31, 2013 and 2012, respectively. The reserve for uncollectible receivables is the Company’s best estimate of the amount of probable credit losses in the existing accounts receivable. The Company determined the reserve based on historical experience and in consideration of current market conditions. Account balances are charged against the allowance when it is anticipated the receivable will not be recovered. | |||||||||
Investments In Debt And Equity Securities | ' | ||||||||
Investments in Debt and Equity Securities. NiSource’s investments in debt and equity securities are carried at fair value and are designated as available-for-sale. These investments are included within “Other investments” on the Consolidated Balance Sheets. Unrealized gains and losses, net of deferred income taxes, are reflected as accumulated other comprehensive income (loss). These investments are monitored for other than temporary declines in market value. Realized gains and losses and permanent impairments are reflected in the Statements of Consolidated Income. No material impairment charges were recorded for the years ended December 31, 2013, 2012 and 2011. | |||||||||
Basis Of Accounting For Rate-Regulated Subsidiaries | ' | ||||||||
Basis of Accounting for Rate-Regulated Subsidiaries. Rate-regulated subsidiaries account for and report assets and liabilities consistent with the economic effect of the way in which regulators establish rates, if the rates established are designed to recover the costs of providing the regulated service and it is probable that such rates can be charged and collected. Certain expenses and credits subject to utility regulation or rate determination normally reflected in income are deferred on the Consolidated Balance Sheets and are recognized in income as the related amounts are included in service rates and recovered from or refunded to customers. | |||||||||
In the event that regulation significantly changes the opportunity for NiSource to recover its costs in the future, all or a portion of NiSource’s regulated operations may no longer meet the criteria for regulatory accounting. In such an event, a write-down of all or a portion of NiSource’s existing regulatory assets and liabilities could result. If transition cost recovery was approved by the appropriate regulatory bodies that would meet the requirements under generally accepted accounting principles for continued accounting as regulatory assets and liabilities during such recovery period, the regulatory assets and liabilities would be reported at the recoverable amounts. If unable to continue to apply the provisions of regulatory accounting, NiSource would be required to apply the provisions of Discontinuation of Rate-Regulated Accounting. In management’s opinion, NiSource’s regulated subsidiaries will be subject to regulatory accounting for the foreseeable future. Refer to Note 8, “Regulatory Matters,” in the Notes to Consolidated Financial Statements for additional information. | |||||||||
Utility Plant And Other Property And Related Depreciation And Maintenance | ' | ||||||||
Utility Plant and Other Property and Related Depreciation and Maintenance. Property, plant and equipment (principally utility plant) is stated at cost. The rate-regulated subsidiaries record depreciation using composite rates on a straight-line basis over the remaining service lives of the electric, gas and common properties as approved by the appropriate regulators. | |||||||||
The weighted average depreciation provisions for utility plant, as a percentage of the original cost, for the periods ended December 31, 2013, 2012 and 2011 were as follows: | |||||||||
2013 | 2012 | 2011 | |||||||
Electric Operations | 3.2 | % | 3.4 | % | 3.5 | % | |||
Gas Distribution and Transmission Operations | 1.8 | % | 1.9 | % | 2.1 | % | |||
For rate-regulated companies, AFUDC is capitalized on all classes of property except organization costs, land, autos, office equipment, tools and other general property purchases. The allowance is applied to construction costs for that period of time between the date of the expenditure and the date on which such project is placed in service. The pre-tax rate for AFUDC was 2.4% in 2013, 3.3% in 2012 and 3.6% in 2011. Short-term borrowings were primarily used to fund construction efforts for all three years presented. | |||||||||
Generally, NiSource’s subsidiaries follow the practice of charging maintenance and repairs, including the cost of removal of minor items of property, to expense as incurred. When regulated property that represents a retired unit is replaced or removed, the cost of such property is credited to utility plant, and such cost, net of salvage, is charged to the accumulated provision for depreciation in accordance with composite depreciation. | |||||||||
In the third quarter of 2013, Columbia Transmission sold storage base gas. The difference between the sale proceeds and amounts capitalized to Utility Plant resulted in a gain of $11.1 million. | |||||||||
Carrying Charges And Deferred Depreciation | ' | ||||||||
Carrying Charges and Deferred Depreciation. Upon completion of units 17 and 18 at the R. M. Schahfer Generating Station, NIPSCO capitalized the debt-based carrying charges and deferred depreciation in accordance with orders of the IURC, pending the inclusion of the cost of each unit in rates. Such carrying charges and deferred depreciation are being amortized over the remaining service life of each unit. | |||||||||
NIPSCO has capitalized debt-based carrying charges and deferred depreciation related to Sugar Creek in accordance with the February 18, 2008 Order of the IURC. The deferral of Sugar Creek debt based carrying charges and the deferral of depreciation ceased in December 2011 and deferred balances are being amortized over five years beginning January 2012. As of December 31, 2013, the remaining balance to be amortized is $42.9 million. An additional $13.9 million is deferred for consideration in NIPSCO's next electric base rate case. Management believes this amount is probable of recovery through future rates. | |||||||||
In 2005, the PUCO authorized Columbia of Ohio to revise its depreciation accrual rates for the period beginning January 1, 2005. The revised depreciation rates are now higher than those which would have been utilized if Columbia of Ohio were not subject to regulation. The amount of depreciation that would have been recorded for 2005 through 2013 had Columbia of Ohio not been subject to rate regulation is a combined $414.2 million, a $53.0 million decrease over the $467.2 million reflected in rates. The regulatory asset was $78.7 million and $84.8 million as of December 31, 2013 and 2012, respectively. The amount of depreciation that would have been recorded for 2013 had Columbia of Ohio not been subject to rate regulation is $66.3 million, a $6.0 million decrease over the $72.3 million reflected in rates. | |||||||||
Amortization Of Software Costs | ' | ||||||||
Amortization of Software Costs. External and internal costs associated with computer software developed for internal use are capitalized. Capitalization of such costs commences upon the completion of the preliminary stage of each project. Once the installed software is ready for its intended use, such capitalized costs are amortized on a straight-line basis generally over a period of five years. NiSource amortized $36.3 million in 2013, $30.6 million in 2012 and $29.0 million in 2011 related to software costs. NiSource’s unamortized software balance was $149.1 million and $142.6 million at 2013 and 2012, respectively. | |||||||||
Goodwill And Other Intangible Assets | ' | ||||||||
Goodwill and Other Intangible Assets. NiSource has approximately $4 billion in goodwill and other intangible assets. Substantially all goodwill relates to the excess of cost over the fair value of the net assets acquired in the Columbia acquisition. In addition, NiSource has other intangible assets consisting primarily of franchise rights apart from goodwill that were identified as part of the purchase price allocations associated with the acquisition of Columbia of Massachusetts, a wholly-owned subsidiary of NiSource, which is being amortized on a straight-line basis over forty years from the date of acquisition. Refer to Note 6, “Goodwill and Other Intangible Assets,” in the Notes to Consolidated Financial Statements for additional information. | |||||||||
Long-Lived Assets | ' | ||||||||
Long-lived Assets. NiSource’s Consolidated Balance Sheets contain significant long-lived assets other than goodwill and intangible assets discussed above which are not subject to recovery under regulatory accounting. As a result, NiSource assesses the carrying amount and potential earnings of these assets whenever events or changes in circumstances indicate that the carrying value could be impaired. Refer to Note 3, “Impairments and Other Charges,” in the Notes to Consolidated Financial Statements for further information. | |||||||||
Revenue Recognition | ' | ||||||||
Revenue Recognition. Revenue is recorded as products and services are delivered. Utility revenues are billed to customers monthly on a cycle basis. Revenues are recorded on the accrual basis and include estimates for electricity and gas delivered but not billed. Cash received in advance from sales of commodities to be delivered in the future is recorded as deferred revenue and recognized as income upon delivery of the commodities. For shorter term transportation and storage service revenues, cash is received at inception of the service period resulting in the recording of deferred revenues that are recognized in revenues over the period the services are provided. | |||||||||
Deferred revenue also includes a gain on conveyances related to pooling of assets (production rights) in a joint undertaking intended to find, develop, or produce oil or gas from a particular property or group of properties. NiSource has a working and an overriding royalty interest in the assets. The gain was initially deferred as NiSource has a substantial obligation for future performance. NiSource recognizes the gain on conveyances into earnings as the obligation is satisfied ($7.3 million in 2013). As of December 31, 2013, remaining gains of approximately $30.0 million were deferred pending performance of future obligations. | |||||||||
Earnings Per Share | ' | ||||||||
Earnings Per Share. Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The weighted average shares outstanding for diluted EPS include the incremental effects of the various long-term incentive compensation plans and the Forward Agreements (see Note 14). The calculation of diluted earnings per share excludes stock options which had an anti-dilutive effect. These options were zero for 2013 and 2012 and 2.8 million for 2011. | |||||||||
The numerator in calculating both basic and diluted EPS for each year is reported net income. The computation of diluted average common shares follows: | |||||||||

(1) On September 10, 2012, NiSource settled the Forward Agreements. Amounts included in diluted average common shares for the year ended December 31, 2012 are weighted for the period prior to settlement. | |||||||||
Estimated Rate Refunds | ' | ||||||||
Estimated Rate Refunds. Certain rate-regulated subsidiaries collect revenues subject to refund pending final determination in rate proceedings. In connection with such revenues, estimated rate refund liabilities are recorded which reflect management’s current judgment of the ultimate outcomes of the proceedings. No provisions are made when, in the opinion of management, the facts and circumstances preclude a reasonable estimate of the outcome. | |||||||||
Accounts Receivable Transfer Program | ' | ||||||||
Accounts Receivable Transfer Program. Certain of NiSource’s subsidiaries have agreements with third parties to sell certain accounts receivable without recourse. These transfers of accounts receivable are accounted for as secured borrowings. The entire gross receivables balance remains on the December 31, 2013 and 2012 Consolidated Balance Sheets and short-term debt is recorded in the amount of proceeds received from the commercial paper conduits involved in the transactions. Fees associated with the securitization transactions are recorded as interest expense. Refer to Note 19, “Transfers of Financial Assets,” in the Notes to Consolidated Financial Statements for further information. | |||||||||
Fuel Adjustment Clause | ' | ||||||||
Fuel Adjustment Clause. NIPSCO defers most differences between fuel and power purchase costs and the recovery of such costs in revenue, and adjusts future billings for such deferrals on a basis consistent with applicable state-approved tariff provisions. | |||||||||
Gas Cost Adjustment Clause | ' | ||||||||
Gas Cost Adjustment Clause. All of NiSource’s Gas Distribution Operations subsidiaries defer most differences between gas purchase costs and the recovery of such costs in revenues, and adjust future billings for such deferrals on a basis consistent with applicable state-approved tariff provisions. | |||||||||
Gas Inventory | ' | ||||||||
Gas Inventory. Both the LIFO inventory methodology and the weighted average cost methodology are used to value natural gas in storage, as approved by regulators for each of NiSource’s regulated subsidiaries. Inventory valued using LIFO was $45.5 million and $48.4 million at December 31, 2013, and 2012, respectively. Based on the average cost of gas using the LIFO method, the estimated replacement cost of gas in storage was greater than the stated LIFO cost by $0.6 million at December 31, 2013 and was less than the stated LIFO cost by $13.2 million at December 31, 2012. Inventory valued using the weighted average cost methodology was $309.1 million at December 31, 2013 and $278.2 million at December 31, 2012. | |||||||||
Accounting For Exchange And Balancing Arrangements Of Natural Gas | ' | ||||||||
Accounting for Exchange and Balancing Arrangements of Natural Gas. NiSource’s Columbia Pipeline Group and Gas Distribution Operations subsidiaries enter into balancing and exchange arrangements of natural gas as part of their operations and off-system sales programs. NiSource records a receivable or payable for its respective cumulative gas imbalances as well as for any gas inventory borrowed or lent under a Gas Distributions Operations exchange agreement. These receivables and payables are recorded as “Exchange gas receivable” or “Exchange gas payable” on NiSource’s Consolidated Balance Sheets, as appropriate. | |||||||||
Accounting For Emissions Allowances | ' | ||||||||
Accounting for Emissions Allowances. NIPSCO has obtained SO2 and NOx emissions allowances from the EPA based upon its electric generation operations that the utility may sell, trade or hold for future use. NIPSCO utilizes the inventory model in accounting for these emissions allowances, whereby these allowances were recognized at zero cost upon receipt from the EPA. Pursuant to the December 21, 2011 IURC Order, all purchases and sales of emission allowances will be recovered or refunded through the EERM. | |||||||||
Accounting For Risk Management And Energy Marketing Activities | ' | ||||||||
Accounting for Risk Management Activities. NiSource accounts for its derivatives and hedging activities in accordance with ASC 815. NiSource recognizes all derivatives as either assets or liabilities on the Consolidated Balance Sheets at fair value, unless such contracts are exempted as a normal purchase normal sale under the provisions of the standard. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and resulting designation. Refer to Note 9, “Risk Management Activities,” in the Notes to Consolidated Financial Statements for additional information. | |||||||||
Income Taxes And Investment Tax Credits | ' | ||||||||
Income Taxes and Investment Tax Credits. NiSource records income taxes to recognize full interperiod tax allocations. Under the liability method, deferred income taxes are provided for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. Previously recorded investment tax credits of the regulated subsidiaries were deferred on the balance sheet and are being amortized to book income over the regulatory life of the related properties to conform to regulatory policy. | |||||||||
To the extent certain deferred income taxes of the regulated companies are recoverable or payable through future rates, regulatory assets and liabilities have been established. Regulatory assets for income taxes are primarily attributable to property related tax timing differences for which deferred taxes had not been provided in the past, when regulators did not recognize such taxes as costs in the rate-making process. Regulatory liabilities for income taxes are primarily attributable to the regulated companies’ obligation to refund to ratepayers deferred income taxes provided at rates higher than the current federal income tax rate. Such amounts are credited to ratepayers using either the average rate assumption method or the reverse South Georgia method. | |||||||||
Pursuant to the Internal Revenue Code and relevant state taxing authorities, NiSource and its subsidiaries file consolidated income tax returns for federal and certain state jurisdictions. NiSource and its subsidiaries are parties to an agreement (Tax Allocation Agreement) that provides for the allocation of consolidated tax liabilities. The Tax Allocation Agreement generally provides that each party is allocated an amount of tax similar to that which would be owed had the party been separately subject to tax. Any net benefit attributable to the parent is reallocated to other members. | |||||||||
Environmental Expenditures | ' | ||||||||
Environmental Expenditures. NiSource accrues for costs associated with environmental remediation obligations when the incurrence of such costs is probable and the amounts can be reasonably estimated, regardless of when the expenditures are actually made. The undiscounted estimated future expenditures are based on currently enacted laws and regulations, existing technology and estimated site-specific costs where assumptions may be made about the nature and extent of site contamination, the extent of cleanup efforts, costs of alternative cleanup methods and other variables. The liability is adjusted as further information is discovered or circumstances change. The reserves for estimated environmental expenditures are recorded on the Consolidated Balance Sheets in “Legal and environmental reserves” for short-term portions of these liabilities and “Other noncurrent liabilities” for the respective long-term portions of these liabilities. Rate-regulated subsidiaries applying regulatory accounting establish regulatory assets on the Consolidated Balance Sheets to the extent that future recovery of environmental remediation costs is probable through the regulatory process. Refer to Note 20, “Other Commitments and Contingencies,” in the Notes to Consolidated Financial Statements for further information. | |||||||||
Excise Taxes | ' | ||||||||
Excise Taxes. NiSource accounts for excise taxes that are customer liabilities by separately stating on its invoices the tax to its customers and recording amounts invoiced as liabilities payable to the applicable taxing jurisdiction. These types of taxes, comprised largely of sales taxes collected, are presented on a net basis affecting neither revenues nor cost of sales. NiSource accounts for other taxes for which it is liable by recording a liability for the expected tax with a corresponding charge to “Other taxes” expense. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | ' |
Derivatives, Policy [Policy Text Block] | ' |
The ASC topic on accounting for derivatives and hedging requires an entity to recognize all derivatives as either assets or liabilities on the Consolidated Balance Sheets at fair value, unless such contracts are exempted, such as normal purchase and normal sale contracts, under the provisions of the ASC topic. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and resulting designation. | |
NiSource uses a variety of derivative instruments (exchange traded futures and options, physical forwards and options, commodity swaps and interest rate swaps) to effectively manage its commodity price risk and interest rate risk exposure. If certain conditions are met, a derivative may be specifically designated as (a) a hedge of the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment, or (b) a hedge of the exposure to variable cash flows of a forecasted transaction. In order for a derivative contract to be designated as a hedge, the relationship between the hedging instrument and the hedged item or transaction must be highly effective. The effectiveness test is performed at the inception of the hedge and each reporting period thereafter, throughout the period that the hedge is designated. Any amounts determined to be ineffective are recognized currently in earnings. For derivative contracts that qualify for the normal purchase and normal sales exception, a contract’s fair value is not recognized in the Consolidated Financial Statements until the contract is settled. | |
Unrealized and realized gains and losses are recognized each period as components of AOCI, regulatory assets and liabilities or earnings depending on the designation of the derivative instrument and regulatory accounting treatment. For subsidiaries that utilize derivatives for cash flow hedges, the effective portions of the gains and losses are recorded to AOCI and are recognized in earnings concurrent with the disposition of the hedged risks. If a forecasted transaction corresponding to a cash flow hedge is no longer probable to occur, the accumulated gains or losses on the derivative are recognized currently in earnings. For fair value hedges, the gains and losses are recorded in earnings each period together with the change in the fair value of the hedged item. As a result of the rate-making process, the rate-regulated subsidiaries generally record gains and losses as regulatory liabilities or assets and recognize such gains or losses in earnings when both the contracts settle and the physical commodity flows. These gains and losses recognized in earnings are then subsequently recovered or passed back to customers in revenues through rates. When gains and losses are recognized in earnings, they are recognized in revenues or cost of sales for derivatives that correspond to commodity risk activities and are recognized in interest expense for derivatives that correspond to interest-rate risk activities. | |
For its commodity price risk programs, NiSource has elected not to net the fair value amounts of its derivative instruments or the fair value amounts recognized for its right to receive or obligation to pay cash collateral arising from those derivative instruments recognized at fair value, which are executed with the same counterparty under a master netting arrangement. NiSource discloses amounts recognized for the right to reclaim cash collateral within “Restricted cash” and amounts recognized for the obligation to return cash collateral within “Other accruals” on the Consolidated Balance Sheets. |
