DISPOSITIONS	(4) DISPOSITIONS 2013 Dispositions In December 2012, we announced our plan to offer for sale certain of our Delaware and Permian Basin properties in southeast New Mexico and West Texas. On February 26, 2013, we announced we signed a definitive agreement to sell these assets for a price of $275.0 million, subject to normal post-closing adjustments. The agreement had an effective date of January 1, 2013 and consequently, operating net revenues after January 1, 2013 were a downward adjustment to the sales price. We closed this disposition on April 1 and we recognized a gain of approximately $83.5 million in second quarter 2013 related to this sale, before selling expenses of $4.2 million. Also in second quarter 2013, we received $14.2 million of proceeds from the sale of miscellaneous oil and gas properties in Pennsylvania and West Texas and we recognized a gain of $4.0 million on these transactions. In the first six months 2013, we also received $10.0 million of proceeds from the sale of miscellaneous oil and gas property in Pennsylvania. 2012 Dispositions In June 2012, we sold a suspended well in the Marcellus Shale for proceeds of $2.5 million resulting in a pre-tax loss of $2.5 million.
