Basis of Presentation

(a) Basis of Presentation

The accompanying condensed consolidated financial statements are prepared in accordance with the instructions to Form 10-Q, are unaudited and do not include all the information and disclosures required by generally accepted accounting principles for complete financial statements. All adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for the interim periods have been made and are of a recurring nature unless otherwise disclosed herein. The results of operations for such interim periods are not necessarily indicative of results of operations for a full year. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the consolidated financial statements for the prior year to conform to the current presentation. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's annual report on Form 10-K for the year ended December 31, 2012.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management of the Company 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 period. Actual results could differ from these estimates.

Joint Investment in E2

(b) Investment in E2

In March 2013, the Company entered into an agreement to form a new company (“E2”) that will provide compression and stabilization services for producers in the liquids-rich window of the Utica Shale play. The Company owns a majority interest in E2 and consolidate its investment in E2 pursuant to FASB ASC 810-10-05-08. The initial investment of approximately $50.0 million will be used to fund new natural gas compression and condensate stabilization facilities. As of March 31, 2013, the Company had invested $22.0 million in E2. E2 will build, own and operate two gas gathering compressor stations and condensate stabilization assets in Noble and Monroe counties in the southern portion of the Utica Shale play in Ohio. E2 serves as the manager and operator of these assets with expected commercial operations to start up during the third quarter of 2013. The Company owns approximately 93.0% of E2 and has pre-determined rights to purchase the management ownership interests of E2 in the future.

Disclosure of Reclassification Amount

(c) Comprehensive Income (Loss)

Accumulated Other Comprehensive Income Reclassifications. In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"). ASU 2013-02 requires disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. For the three months ended March 31, 2013 and 2012, the Partnership reclassified cash flow hedge (gains)/losses in the amounts of ($0.3) million and $0.1million, respectively, included in other comprehensive income to revenues on the condensed consolidated statement of operations.
