EME's accrued capital expenditures at December 31, 2012, 2011 and 2010 were $31 million, $29 million and $58 million, respectively. Accrued capital expenditures will be included as an investing activity in the consolidated statements of cash flows in the period paid.

In connection with certain EME wind projects acquired during the past five years, the purchase price included payments that were due upon the completion of specific construction activities or the achievement of operational milestones. Accordingly, EME accrues for estimated payments when the obligation is probable. These incremental purchase price payments are capitalized.
