Acquisitions	L. Acquisitions On June 3, 2013, the Company acquired approximately 99,000 net acres in southwestern Pennsylvania and ten horizontal Marcellus wells, located in Washington County, Pennsylvania, from Chesapeake Energy Corporation and its partners (Chesapeake) for approximately $114.6 million. The acreage includes 67,000 Marcellus acres, of which 42,000 acres are unlikely to be developed due to near-term lease expirations or a scattered footprint. Of the total purchase price, $56.7 million was allocated to the undeveloped acreage and $57.9 million was allocated to the acquired Marcellus wells. The Marcellus wells are expected to add approximately 2.0 Bcfe of production sales volumes in 2013 and represent approximately 54.0 Bcfe of proved developed reserves. As the transaction qualifies as a business combination under United States GAAP, the fair value of the acquired assets was determined using a market approach for the undeveloped acreage and a discounted cash flow model under the income approach for the wells. Significant unobservable inputs used in the analysis included the determination of estimated developed reserves and NYMEX forward pricing, which classify the acquired assets as a Level 3 measurement.
