Information Regarding Forward-Looking Statements

This report includes forward-looking statements. These forward-looking statements are identified as any statement that does not relate strictly to historical or current facts. They use words such as “anticipate,” “believe,” “intend,” “plan,” “projection,” “forecast,” “strategy,” “position,” “continue,” “estimate,” “expect,” “may,” or the negative of those terms or other variations of them or comparable terminology. In particular, expressed or implied statements concerning future actions, conditions or events, future operating results or the ability to generate sales, income or cash flow or to make distributions are forward-looking statements. Forward-looking statements are not guarantees of performance. They involve risks, uncertainties and assumptions. Future actions, conditions or events and future results of operations may differ materially from those expressed in these forward-looking statements. Many of the factors that will determine these results are beyond our ability to control or predict.

See Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014 (2014 Form 10-K) for a more detailed description of factors that may affect the forward-looking statements. When considering forward-looking statements, one should keep in mind the risk factors described in our 2014 Form 10-K. The risk factors could cause our actual results to differ materially from those contained in any forward-looking statement. Because of these risks and uncertainties, you should not place undue reliance on any forward-looking statement. We disclaim any obligation, other than as required by applicable law, to update the results of any revisions to any forward looking statements to reflect future events or developments.

COLORADO INTERSTATE GAS COMPANY, L.L.C. AND ~~SUBSIDIARIES~~SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. General

Organization

We are a Delaware limited liability company, originally formed in 1927 as a corporation. We are an interstate pipeline system serving the Rocky Mountain Region. Unless the context otherwise requires, references to “us,” “we,” “our,” “ours” or “CIG,” are describing Colorado Interstate Gas Company, L.L.C. and its consolidated ~~subsidiaries~~subsidiary.

Prior to January 1, 2015, we were wholly owned by El Paso Pipeline Partners Operating Company, L.L.C. (EPPOC), a wholly owned subsidiary of El Paso Pipeline Partners, L.P. (EPB), a master limited partnership indirectly controlled by Kinder Morgan, Inc. (KMI). On January 1, 2015, EPB and its subsidiary, EPPOC, merged with and into Kinder Morgan Energy Partners, L.P. (KMP), with KMP surviving the merger. As a result of such merger, we became a direct, wholly owned subsidiary of KMP, which is a subsidiary of KMI.

Basis of Presentation

We have prepared our accompanying unaudited consolidated financial statements under the rules and regulations of the United States Securities and Exchange Commission (SEC). These rules and regulations conform to the accounting principles contained in the Financial Accounting Standards Board’s (FASB) Accounting Standards Codification (the “Codification”), the single source of Generally Accepted Accounting Principles in the United States of America (GAAP) and referred to in this report as the Codification. Under such rules and regulations, we have condensed or omitted certain information and notes normally included in financial statements prepared in conformity with the Codification. We believe, however, that our disclosures are adequate to make the information presented not misleading.

Our accompanying consolidated financial statements reflect normal adjustments, and also recurring adjustments that are, in the opinion of our management, necessary for a fair presentation of our financial results for the interim periods. Certain amounts from prior periods have been reclassified to conform to the current presentation. Interim results are not necessarily indicative of results for a full year; accordingly, you should read these consolidated financial statements in conjunction with our consolidated financial statements and related notes included in our 2014 Form 10-K.

In the second quarter of 2015, we adopted Accounting Standards Update (ASU) 2015-03, “Interest-Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs.” This ASU is designed to simplify presentation of debt issuance costs. The standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The application of this new accounting guidance resulted in the reclassification of $1 million of debt issuance costs from “Deferred charges and other assets” to “Long-term debt” on our accompanying Consolidated Balance Sheets as of ~~June~~ September 30, 2015 and December 31, 2014.

2. Debt

We classify our debt based on the contractual maturity dates of the underlying debt instruments. We defer costs associated with debt issuance over the applicable term. These costs are then amortized as interest expense in our Consolidated Statements of Income. The following table summarizes the net carrying value of our outstanding debt (in millions):

	June 30, 2015		December 31, 2014
	September 30, 2015		December 31, 2014
Senior Notes, 5.95%, due March 2015	$	—	$	35
Senior Notes, 6.80%, due November 2015(a)	340		340
Senior Debentures, 6.85%, due June 2037	100		100
Other financing obligations	~~171~~170		173
	611		648
	610		648
Less: Unamortized debt issuance costs	1		1
Total debt and other financing obligations	~~610~~609		647
Less: Current portion of debt	~~345~~346		381
Total debt and other financing obligations, less current maturities	$	~~265~~263	$	266

__________

(a) AsWe ~~of June 30, 2015, we~~ included $340 million of our 6.80% senior notes due November 15, 2015 within the caption “Current portion of debt” on our Consolidated Balance Sheets. We intend to satisfy this debt through the issuance of long-term debt, borrowings from our cash management agreement with KMI, equity contribution from our parent or a combination of these options.

KMI and substantially all of its ~~wholly owned~~ domestic subsidiaries, including us, entered into a cross guarantee agreement whereby each party to the agreement unconditionally guarantees, jointly and severally, the payment of specified indebtedness of each other party to the agreement.

Debt Repayment

In March 2015, we repaid $35 million of our 5.95% senior notes.

Debt Covenants

As of ~~June~~September 30, 2015, we were in compliance with all of our debt covenants. For a further discussion of our debt, see our 2014 Form 10-K.

3. Fair Value

The following table reflects the carrying amount and estimated fair value of our debt, excluding total other financing obligations (in millions):

	June 30, 2015				December 31, 2014
	September 30, 2015				December 31, 2014
	CarryingAmount		Estimated FairValue		CarryingAmount		Estimated FairValue
Total debt, excluding total other financing obligations (a)	$	439	$	~~454~~437	$	474	$	507

___________________

(a) Our other financing obligations were $~~171~~170 million and $173 million as of ~~June~~September 30, 2015 and December 31, 2014, of which $56 million ~~and~~for $6both ~~million,~~periods ~~respectively,~~ was reported as “Current portion of debt” on our Consolidated Balance Sheets. For a further discussion of our other financing obligations, see our 2014 Form 10-K.

We separate the fair values of our financial instruments into levels based on our assessment of the availability of observable market data and the significance of non-observable data used to determine the estimated fair value. We estimated the above fair values of debt, excluding total other financing obligations, primarily based on quoted market prices for the same or similar issues, a Level 2 fair value measurement. Our assessment and classification of an instrument within a level can change over time based on the maturity or liquidity of the instrument and this change would be reflected at the end of the period in which the change occurs. During the ~~six~~nine months ended ~~June~~September 30, 2015, there were no changes to the inputs and valuation techniques used to measure fair value of these instruments, or the levels in which they were classified.

Table of Contents

As of ~~June~~September 30, 2015 and December 31, 2014, the carrying amounts of accounts receivable and accounts payable represent their fair values based on the short-term nature of these items. The carrying ~~amount~~amounts of our affiliate note receivable and note payable approximates ~~its~~their fair value due to the ~~note being due on demand and the~~ market-based nature of the interest rate.

4. Related Party Transactions

Cash Management Program

We participate in the cash management program with KMI and its affiliates, which matches short-term cash surpluses and needs of participating affiliates, thus minimizing total borrowings from outside sources. KMI and its affiliates use the cash management program to settle intercompany transactions between participating affiliates. As of ~~June~~September 30, 2015, we had a note payable to KMI of $138 million. As of December 31, 2014, we had a note receivable from KMI of $36 million. These amounts are included in “Note payable to affiliate” and “Note receivable from affiliate” on our Consolidated Balance Sheets and are presented as cash activity in our Consolidated Statements of Cash Flows. The interest rate on this note was variable and was 1.43% and 1.5% as of ~~June~~September 30, 2015 and December 31, 2014, respectively.

Affiliate Balances

We enter into transactions with our affiliates within the ordinary course of business including long-term contracts providing for natural gas transportation services to and from affiliates, and various operating agreements. Such transactions are conducted in accordance with all applicable laws and regulations and on an arms’ length basis consistent with our policies governing such transactions. For a further discussion of our affiliate transactions, see our 2014 Form 10-K.

The following table summarizes our balance sheet affiliate balances (in millions):

5. Litigation and Environmental Contingencies

We are party to various legal, regulatory and other matters arising from the day-to-day operations of our business that may result in claims against us. Although no assurance can be given, we believe, based on our experiences to date and taking into account established reserves, that the ultimate resolution of such items will not have a material adverse impact on our business, financial position, results of operations or cash flows. We believe we have meritorious defenses to the matters to which we are a party and intend to vigorously defend these matters. When we determine a loss is probable of occurring and is reasonably estimable, we accrue an undiscounted liability for such contingencies based on our best estimate using information available at that time. If the estimated loss is a range of potential outcomes and there is no better estimate within the range, we accrue the amount at the low end of the range. We disclose contingencies where an adverse outcome may be material, or in the judgment of management, we conclude the matter should otherwise be disclosed. We had no accruals for any outstanding legal proceedings as of ~~June~~September 30, 2015 and December 31, 2014.

Environmental Matters

We are subject to environmental cleanup and enforcement actions from time to time. Our operations are subject to federal, state and local laws and regulations relating to protection of the environment. Although we believe our operations are in substantial compliance with applicable environmental law and regulations, risks of additional costs and liabilities are inherent in our operations, and there can be no assurance that we will not incur significant costs and liabilities. Moreover, it is possible that other developments, such as increasingly stringent environmental laws, regulations and enforcement policies under the terms of authority of those laws, and claims for damages to property or persons resulting from operations, could result in substantial costs and liabilities to us.

~~General~~Although it is not possible to predict the ultimate outcomes, we believe that the resolution of the environmental matters, and other matters to which we are a party, will not have a material adverse effect on our business, financial position, results of operations or cash flows. As of September 30, 2015 and December 31, 2014, we had approximately $1 million accrued for our environmental matters.

Although it is not possible to predict the ultimate outcomes, we believe that the resolution of the environmental matters, and other matters to which we are a party, will not have a material adverse effect on our business, financial position, results of operations or cash flows. As of June 30, 2015 and December 31, 2014, we had approximately $1 million accrued for our environmental matters.

6. Accounting for Regulatory Activities

Regulatory Assets and Liabilities

Regulatory assets and liabilities represent probable future revenues or expenses associated with certain charges and credits that will be recovered from or refunded to customers through the ratemaking process. As of ~~June~~September 30, 2015, the regulatory assets are being recovered as cost of service in our rates over a period of approximately 1 year to 27 years. For a detailed discussion of our regulatory assets and liabilities, see our 2014 Form 10-K.

The following table summarizes our regulatory asset and liability balances (in millions):

	June 30, 2015		December 31, 2014
	September 30, 2015		December 31, 2014
Current regulatory assets	$	1112	$	12

Rates and Regulatory Matter

In August 2011, the Federal Energy Regulatory Commission approved an uncontested pre-filing settlement of a rate case required under the terms of a previous settlement. The settlement generally provides for (i) our current tariff rates to continue until our next general rate case, which will be effective no later than October 1, 2016,; (ii) contract extensions to March 2016,; (iii) a revenue sharing mechanism with certain of our customers for certain revenues above annual threshold amounts; and (iv) a revenue surcharge mechanism with certain of our customers to charge for certain shortfalls of revenue that are less than an annual threshold amount.

7. Recent Accounting Pronouncements

ASU No. 2014-09

On May 28, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” This ASU is designed to create greater comparability for financial statement users across industries and jurisdictions. The provisions of ASU No. 2014-09 include a five-step process by which entities will recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which an entity expects to be entitled in exchange for those goods or services. The standard also will require enhanced disclosures, provide more comprehensive guidance for transactions such as service revenue and contract modifications, and enhance guidance for multiple-element arrangements. ASU No. 2014-09 will be effective for ~~U.S.~~us ~~public companies for annual reporting periods beginning after December 15, 2017, including interim reporting periods (~~January 1, 2018 ~~for us)~~. Early adoption is permitted tofor the interim periods within the ~~year of~~ adoption year. We are currently reviewing the effect of ASU No. 2014-09 on our revenue recognition and assessing the timing of our adoption.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

General and Basis of Presentation

The following information should be read in conjunction with (i) our accompanying interim consolidated financial statements and related notes, (ii) our consolidated financial statements and related notes included in our 2014 Form 10-K, and (iii) our management’s discussion and analysis of financial condition and results of operations included in our 2014 Form 10-K. The information required by this Item is presented in a reduced disclosure format pursuant to General Instruction H to Form 10-Q.

Results of Operations

Earnings Results

Our management assesses our earnings performance based on earnings before depreciation and amortization, which excludes depreciation and amortization (DD&A), general and administrative expenses and interest expense, net. General and administrative expenses include items such as employee benefits, legal, information technology and other costs that are not controllable by operating management and thus are not included in the measure of performance for which they are accountable. Our management uses earnings before DD&A as a measure to assess the operating results and effectiveness of our assets. We believe providing earnings before DD&A to our investors is useful because it is the same measure used by management to evaluate our performance and allows investors to evaluate our operating results without regard to our financing methods. Earnings before DD&A may not be comparable to measures used by other companies. Additionally, earnings before DD&A should be considered in conjunction with net income and other performance measures such as operating income or operating cash flows.

Below are the components of earnings before DD&A for the periods presented (in millions):

Earnings before DD&A

Our earnings before DD&A increased by $17 million for the ~~six~~nine months ended ~~June~~September 30, 2015 as compared to the same period in 2014. The increase was primarily driven by (i) $48 million of higher firm revenues largely due to the High Plains expansion project, which was placed in service in March 2014; ~~and~~(ii) lower operating costs of $610 million associated with our liquids processing plants mainly due to plant shut down to perform maintenance; and (iii) $3 million of lower operating expenses primarily due to lower field operation and maintenance expenses and property taxes. These favorable impacts were partially offset by (i) $610 million of lower liquids revenues primarily due to a plant shut down to perform maintenance and lower liquids prices; (ii) ~~higher~~an increase in operating expenses ofbetween the comparable periods due to $3 million ~~due~~of tolower first quarter of 2014 operating expenses as a result of favorable rates on gas used for system balancing ~~in first quarter 2014~~; and (iii) $1 million of lower cashout revenues.

Item 4. Controls and Procedures.

As of ~~June~~September 30, 2015, our management, including our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Securities Exchange Act of 1934.
