Schedule of Contract Balances and Changes in Contract Balances | Contract Balances: Contract assets consist primarily of unbilled amounts resulting from long-term contracts when revenue recognized exceeds the amount billed often due to billing schedule timing. Contract liabilities result from advance payments received on a contract or from billings in excess of revenue recognized on long-term contracts due to billing schedule timing. The net contract assets (liabilities) as of March 31, 2021 increased by $19.2 million as compared to December 31, 2020. The increase in net contract assets (liabilities) is primarily due to an increase in work in the energy, environmental, and infrastructure client market and health, education, and social programs client market, offset by decreases in work in the consumer and financial market. There were no material changes to contract balances due to impairments during the period. During the three months ended March 31, 2021 and 2020, the Company recognized $15.1 million and $17.3 million in revenue related to the contract liabilities balance at December 31, 2020 and 2019, respectively.
