Note 3 – Assets Held for Sale and Divestitures

Assets Held for Sale

Assets are classified as held for sale when the Company commits to a plan to sell the assets and there is reasonable certainty the sale will take place within one year. Upon classification as held for sale, long-lived assets are no longer depreciated or depleted, and a measurement for impairment is performed to identify and expense any excess of carrying value over fair value less estimated costs to sell. Any subsequent changes to the fair value less estimated costs to sell impact the measurement of assets held for sale with any gain or loss reflected in the net gain (loss) on divestiture activity line item in the accompanying condensed consolidated statements of operations (“accompanying statements of operations”).

As of June 30, 2016, the accompanying condensed consolidated balance sheets (“accompanying balance sheets”) present $173.0 million of assets held for sale, net of accumulated depletion, depreciation, and amortization expense, which consists of certain non-core assets in each of the Company’s operating regions. A corresponding aggregate asset retirement obligation liability of $32.1 million is separately presented. Certain of these assets were written down by $68.3 million to reflect fair value less estimated costs to sell upon reclassification to assets held for sale, as of March 31, 2016. During the second quarter of 2016, the Company estimated an increase in the fair value of certain previously impaired assets held for sale due to an increase in estimated selling prices, as evidenced by recent bid prices received from third parties, resulting in a $49.5 million gain recorded for the three months ended June 30, 2016. The Company expects to close the asset sale transactions prior to December 31, 2016. There were no material assets held for sale as of December 31, 2015.

Subsequent to June 30, 2016, the Company entered into separate purchase and sale agreements for the sale of certain of its Permian and Rocky Mountain assets that were classified as held for sale as of June 30, 2016. The Company expects to close these transactions prior to December 31, 2016. The closings of these transactions are subject to the satisfaction of customary closing conditions, and there can be no assurance that these transactions will close on the expected closing dates or at all.

Divestitures

During the second quarter of 2015, the Company divested its Mid-Continent assets in separate packages for total cash proceeds received at closing of $316.5 million and recorded an estimated net gain of $107.8 million for the six months ended June 30, 2015. These assets were classified as held for sale as of March 31, 2015, and certain of these assets were written down by $30.0 million during the three months ended March 31, 2015, to reflect their fair value less estimated costs to sell. This write-down is reflected in the total net gain of $107.8 million discussed above. In conjunction with this divestiture, the Company closed its Tulsa, Oklahoma office in 2015 and incurred $5.0 million and $8.5 million of exit and disposal costs for the three and six months ended

June 30, 2015, respectively. Offsetting the net gain recorded on the divestiture of the Company’s Mid-Continent assets were write-downs recorded during the three months ended June 30, 2015, on certain other assets held for sale totaling $66.0 million.

The Company determined that neither these planned nor executed asset sales qualified for discontinued operations accounting under financial statement presentation authoritative guidance.
