Divestitures	Note 2 — Divestitures Appalachian Basin Sale—In December 2010, the Company entered into an agreement with Magnum Hunter Resources Corporation (“MHR”) to sell certain oil and gas properties and related assets in West Virginia. The sale closed in three phases in December 2010, January 2011 and June 2011 for a total of $44.6 million. The amount received for the first and second phases was paid half in cash and half in MHR common stock, while the amount received for the third phase was paid entirely in cash. Gains of $9.9 million and $2.5 million, net of $225,000 and $2.4 million in selling costs and adjustments, were recorded in January 2011 and June 2011 related to the second and third phases of the sale. The corresponding reduction in the Company’s oil and gas full cost pool was $1.5 million for the second closing, with no reduction for the third closing. Of the total proceeds received from all three phases of the sale, $6.4 million was set aside in escrow to cover potential claims for indemnity and title defects. In June 2012, $5.7 million of escrowed funds relating to the first and second closing was released after net claims of $219,000 were paid. Of the $5.7 million released to the Company, $1.3 million was retained by the Company while $4.4 million was paid to Royal Bank of Canada (“RBC”) under the previously disclosed asset sale agreement with RBC. The $219,000 of net claims paid out of escrow effectively reduced the net proceeds received on the sale, and along with certain post-closing adjustments, resulted in a $56,000 reduction in the gain on sale recognized in June 2012. At June 30, 2012, the remaining balance in escrow was $564,000. The balance is related to the third closing and scheduled to be released in December 2012. The escrow balance is reflected in the condensed consolidated balance sheet as a component of other current assets. If the entire remaining amount in escrow is released, the Company would retain $164,000 while $400,000 will be paid to a third-party. The amount payable to the third party is reflected in the condensed consolidated balance sheet in “accrued expenses and other.”
