Transaction Price Allocated to Remaining Performance Obligations

As of March 31, 2021, the aggregate amount of transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) for executed contracts approximates $13.07 billion of which we expect to recognize approximately 30% of the revenue over the next 12 months and the remainder thereafter.

Contract Liabilities

Customer payments received in advance of satisfaction of the related performance obligations are deferred as contract liabilities. Such amounts are classified in our condensed consolidated balance sheets as "Deferred revenue". During the three months ended March 31, 2021, we recognized $138 million of revenues that were included in our contract liability balance at the beginning of such period.

Significant Customers

Revenues attributable to our relationships (as the prime contractor or a subcontractor) with U.S. government agencies, within our Domestic segment, comprised 20% and 17% of our consolidated revenues for the first three months of 2021 and 2020, respectively. Amounts due in connection with these relationships comprised 16% and 13% of client receivables as of March 31, 2021 and December 31, 2020, respectively.
