Acquisitions and divestitures

2014 Divestitures

During 2014, we closed on the sales of four of the five property packages that comprise our plan to divest our assets in Ark-La-Tex, Permian Basin, Gulf Coast, and North Texas. The five packages include: (i) our Fort Worth Basin package located in North Texas; (ii) our Delaware Basin package; (iii) our Central Basin Platform package; (iv) our Ark-La-Tex package; and (v) our Gulf Coast package. In May 2014, we sold our Fort Worth Basin package to Scout Energy Group I, LP, for cash proceeds of $23,702 and we sold our Delaware Basin package to RKI Exploration & Production, LLC for cash proceeds of $124,717. In July 2014, we sold our Ark-La-Tex and Central Basin Platform property packages to RAM Energy, LLC (“RAM”) for cash proceeds of $49,078 and $46,830, respectively. Proceeds from these property packages are net of post-closing adjustments. As these properties did not represent a material portion of our oil and natural gas reserves, individually or in the aggregate, we did not record any gain or loss on the sales and instead, reduced our full cost pool by the amount of the net proceeds without significant alteration to our depletion rate.

In addition to the packages discussed above, we had various other divestitures during the year ended December 31, 2014. These divestitures resulted in cash proceeds of $20,007 from the sale of leasehold interests in the Eagle Ford Formation in Texas and $24,478 from the sale of various other properties predominantly located in Andrews County, Texas, which comprised part of our Permian Basin properties, and Osage County, Oklahoma.

2013 Acquisition and divestitures

Cabot Acquisition. In late 2013, we acquired additional oil and natural gas properties consisting of approximately 131,000 (66,000 net) acres in the Panhandle Marmaton play from Cabot Oil & Gas Corporation for approximately $153,858, net of pre-closing purchase price adjustments and subject to post closing adjustments (the “Cabot Acquisition”). The Cabot Acquisition expanded our presence in the Panhandle Marmaton play, adding oil and natural gas reserves and production to our existing asset base in this area.

Our acquisition qualified as a business combination for accounting purposes and, as such, we estimated the fair value of the acquired properties as of the December 18, 2013 acquisition date, which was the date on which we obtained control of the properties. The fair value of the assets and liabilities acquired was estimated using assumptions that represent Level 3 inputs. See “Note 7—Fair value measurements” for additional discussion of the measurement inputs.

We estimated the consideration paid for these properties approximated the fair value that would be paid by a typical market participant. As a result, no goodwill or bargain purchase gain was recognized in conjunction with the purchase. Acquisition-related costs of $951 have been expensed as incurred in general and administrative expense in the accompanying consolidated statements of operations for the year ended December 31, 2013.

The following table summarizes the consideration paid to acquire the properties and the amounts of the assets acquired and liabilities assumed as of December 18, 2013.

The following unaudited pro forma combined results of operations for the years ended December 31, 2013 and 2012 are presented as though we completed the Cabot Acquisition as of January 1, 2012. The pro forma combined results of operations for the years ended December 31, 2013 and 2012 have been prepared by adjusting the historical results of the acquired properties and estimates of the effect of the transaction on the combined results. These supplemental pro forma results of operations are provided for illustrative purposes only and do not purport to be indicative of the actual results that would have been achieved had the transaction been in effect for the periods presented or that may be achieved by us in the future. Future results may vary significantly from the results reflected in this pro forma financial information because of future events and transactions, as well as other factors. The pro forma information below includes adjustments for depletion, depreciation, amortization and accretion expense, interest expense, acquisition costs, and related income tax effects.

Divestitures. During 2013, we sold various oil and natural gas properties for total cash proceeds of approximately $109,710. These included properties in Creek, Love and Carter counties, Oklahoma, that were sold for approximately $61,440 and properties in Texas County, Oklahoma, that were sold for approximately $17,800. In accordance with the full cost method of accounting, we reduced our full cost pool by the amount of the net proceeds and did not record a gain or loss on the sale.

On May 30, 2012, we sold certain mature oil and natural gas properties located in our Velma Area in southern Oklahoma for a cash price of $37,000 subject to post-closing adjustments. In accordance with the full cost method of accounting, we reduced our full cost pool by the amount of the net proceeds and did not record a gain or loss on the sale.
