On July 25, 2014, the Company signed a definitive Stock Purchase Agreement to sell our Wheelabrator business to an affiliate of Energy Capital Partners for $1.94 billion in cash, subject to certain post-closing adjustments. Closing of the sale is expected to occur by the end of 2014, subject to the satisfaction of customary closing conditions and receipt of regulatory approvals. In conjunction with the sale, the Company will enter into a long-term agreement to supply waste to certain Wheelabrator facilities upon closing.
