(a) The Company sold its interest in the Four Corners Generating Station ("Four Corners") for approximately $32.0 million based on the book value as defined in the asset purchase agreement entered into by the Company and Arizona Public Service Company ("APS") on February 17, 2015 (the "Purchase and Sale Agreement"). The sales price was adjusted downward by $7.0 million and $19.5 million, respectively, to reflect APS assumption of the Company's obligation to pay for future plant decommissioning and mine reclamation expense. The sales price was also adjusted downward by approximately $1.3 million for closing adjustments and other assets and liabilities assumed by APS. At the closing of the sale, the Company received approximately $4.2 million in cash, subject to post-closing adjustments. Subsequently, the Company recorded post-closing adjustments to reflect adjustments to estimated capital expenditures and other assets and liabilities assumed by APS through July 6, 2016, which resulted in a $1.6 million refund due to APS.
