(QEP or the Company) is a holding company with two major subsidiaries, QEP Energy Company and QEP Marketing Company, which are engaged in two primary lines of business: (i) oil and gas exploration and production (QEP Energy) and (ii) oil and gas marketing, operation of the Haynesville Gathering System and a underground gas storage reservoir (QEP Marketing and Other). QEP's operations are focused in two geographic regions: the Northern Region (primarily in North Dakota, Wyoming and Utah) and the Southern Region (primarily in Texas and Louisiana) of the United States. QEP's corporate headquarters are located in Denver, Colorado. In December 2013, QEP's Board of Directors authorized the Company to develop a plan to separate its midstream business, QEP Field Services, including the Company's interest in QEP Midstream Partners, LP (“QEP Midstream”), from QEP. Between December 2013 and September 2014, the Company evaluated transaction alternatives, including selling or merging the midstream business or spinning the midstream business off to its shareholders. In June 2014, QEP filed a registration statement on Form 10 with the U.S. Securities and Exchange Commission (SEC) in preparation for a potential spinoff of QEP Field Services as a separate publicly traded company. Concurrently, the Company evaluated selling or merging its midstream business. In September 2014, based on the proposals received, the Company's Board of Directors authorized QEP's management to engage in the negotiation of terms of a definitive transaction with Tesoro Logistics LP ("Tesoro"). In October 2014, the Company announced that its wholly owned subsidiary, QEP Field Services, had entered into a definitive agreement to sell substantially all of its midstream business, including the Company's ownership interest in QEP Midstream to Tesoro in an all cash transaction valued at $2.5 billion, including $230.0 million to refinance debt at QEP Midstream. The transaction is subject to customary closing conditions and regulatory approvals, and is expected to close before year-end 2014. On October 31, 2014, the Federal Trade Commission granted early termination, ending the Hart Scott Rodino waiting period for the transaction. The decision to sell the midstream business is a result of the Company’s ongoing review of strategic alternatives to maximize shareholder value. QEP will retain ownership of QEP Field Services’ Haynesville Gathering System. As a result of the pending transaction, the QEP Field Services reporting segment, excluding the retained ownership of the Haynesville Gathering System, has been classified as assets and liabilities held for sale on the Condensed Consolidated Balance Sheet and as a discontinued operation on the Condensed Consolidated Statement of Operations and the notes accompanying the Condensed Consolidated Financial Statements. For reporting purposes, the retained Haynesville Gathering System has been combined with QEP Marketing and Other.
