NOTE G—COMMITMENTS AND CONTINGENCIES—(continued)

Environmental

The Company is subject to extensive federal, state and local environmental laws and regulations. These laws, which are often changing, regulate the discharge of materials into the environment and may require the Company to remove or mitigate the environmental effects of the disposal or release of petroleum or chemical substances at various sites. Environmental expenditures are expensed as incurred. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures of a noncapital nature are recorded when environmental assessment and/or remediation is probable and the costs can be reasonably estimated. Such liabilities are generally undiscounted unless the timing of cash payments is fixed and readily determinable. Management believes no liabilities of this nature existed at March 31, 2012 or December 31, 2011.

NOTE H—MAJOR CUSTOMERS

During the three months ended March 31, 2012, the Company had four customers accounting for 29%, 18%, 13% and 10% of its total revenues, respectively. Chief Exploration & Development LLC, an affiliate, accounted for 5% of total revenues during the three months ended March 31, 2012.

Report of Independent Certified Public Accountants

The Member

Chief Gathering LLC

We have audited the accompanying balance sheets of Chief Gathering LLC (the “Company”, a Texas limited liability company) as of December 31, 2011, 2010, and 2009, and the related statements of operations, changes in member’s capital, and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Chief Gathering LLC as of December 31, 2011, 2010, and 2009, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

December 31, 2011, 2010 and 2009

NOTE A—NATURE OF OPERATIONS

Chief Gathering LLC (the “Company”) is a Texas limited liability company that constructs and operates pipelines within the Marcellus shale in Pennsylvania and West Virginia to deliver natural gas from wellheads to interstate and intrastate pipelines that ultimately redeliver to industrial end users and consumers. The Company is a wholly owned subsidiary of Chief E&D Holdings, L.P (“Chief”).

NOTE B—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 these estimates.

Accounts Receivable

Substantially all of the Company’s accounts receivable are due from producers of natural gas in the Marcellus Shale. As additional customers are continually added, the Company believes that the loss of these producers would not result in a material adverse effect on its operations. The Company reviews its need for an allowance on a periodic basis and writes off accounts receivable when they become uncollectible. The Company determines the allowance by considering the length of time past due, previous history, and debtor’s ability to pay its obligation, among other things. As of December 31, 2011, 2010, and 2009, no allowance for doubtful accounts or write offs related to trade accounts receivable have been recorded.

Revenue Recognition

Revenue is determined primarily by the volumes of natural gas gathered, compressed, and treated through the Company’s pipeline and gathering systems. Revenues are generated principally under fee-based arrangements in which the Company receives a fee for natural gas gathering, compressing, or treating services. The revenue earned from these arrangements is directly related to the volume of natural gas that flows through the Company’s systems and is not directly related to commodity prices.

Inventory

Inventory consists of line pipe and parts on hand for future pipeline activities. Due to the expected use of inventory in the construction of the Company’s pipeline and gathering system, it has been classified as a non-current asset in the balance sheet. Inventory is stated at the lower of cost or market under the weighted average method. There were no inventory adjustments during 2011, 2010, or 2009.

Property and Equipment

Property and equipment are comprised of natural gas pipelines and facilities. These items are recorded at cost and are amortized by the straight-line method over their estimated useful lives of 20 years. Maintenance and repairs are expensed as incurred.

Related interest expense incurred during the construction of the gathering system is capitalized. Interest costs capitalized during 2011 and 2010 totaled $180,000 and $240,000, respectively, and are included in property and equipment.

14

The Company’s long-lived assets used in operations are assessed for impairment whenever changes in facts and circumstances indicate a possible significant deterioration in the future cash flows expected to be generated by an asset group. If, upon review, the sum of the undiscounted pretax cash flows is less than the carrying value of the asset group, the carrying value is written down to estimated fair value. The fair value of impaired assets is determined based on quoted market prices in active markets, if available, or upon the present value of expected future cash flows using discount rates commensurate with the risk involved in the asset group. There were no impairment indicators during 2011, 2010, or 2009.

Asset Retirement Obligations

The Company follows the provisions of Accounting Standards Codification (“ACS”) 410, Accounting for Asset Retirement Obligations. When estimable, the present value of a legal liability for an asset retirement obligation is recorded in the period it is incurred. The asset retirement obligation primarily relates to costs to dismantle, relocate or dispose gathering systems and related structures. Determination of the amounts to be recognized is based upon numerous estimates and assumptions, including expected settlement dates, future retirement costs, future inflation rates and the credit-adjusted risk-free interest rates. However, management was not able to reasonably measure the fair value of the asset retirement obligations as of December 31, 2011, 2010, or 2009 because the settlement dates were indeterminable. The Company will record an asset retirement obligation in the periods in which management can reasonably determine the settlement dates.

Income Taxes

Generally, income or loss of the Company is allocated to the member for inclusion in its respective tax returns. Accordingly, no provision is made for federal or local income taxes in the accompanying financial statements.

The Company is part of a group that files a Texas franchise tax return on a consolidated basis with Chief, its parent. Because the Company has no significant operations in Texas, it has not incurred state franchise taxes.

On January 1, 2009, the Company adopted ASC 740 Accounting for Uncertainty in Income Taxes—An Interpretation of FASB Statement No. 109. ASC 740 clarifies the accounting for uncertainties in income taxes recognized in an enterprise’s financial statements in accordance with ASC 450. ASC 740 also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 provides guidance on de-recognition, classification, interest and penalties, disclosures, and transition.

As required by the uncertain tax position guidance in ASC 740, the Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant tax authority. At the adoption date, the Company applied the uncertain tax position guidance in ASC 740 to all tax positions for which the statute of limitations remained open. The adoption of this standard had no material impact on the Company. The Company has no material uncertain tax positions as of December 31, 2011, 2010, or 2009.
