Our contract liabilities consist of deferred revenue received from reimbursable projects. The noncurrent portion of deferred revenue is included in other long-term liabilities on our condensed consolidated balance sheets.

The following table summarizes changes in contract liabilities included in our condensed consolidated balance sheets:

Revenue recognized (a)	(1)
Balance, end of period	$	35

The contract liabilities disclosed in the table above will be recognized as revenue as the obligations are satisfied over their average remaining contract life, which is 35 years as of June 30, 2020.
