Schedule of Contract Assets and Liabilities and Changes in Contract Balances | Contract Assets and Liabilities: Contract assets consist of unbilled receivables on contracts where revenue recognized exceeds the amount billed. Contract liabilities result from advance payments received on a contract or from billings in excess of revenue recognized on long-term contracts. The following table summarizes the contract balances as of December 31, 2024 and December 31, 2023:
| December 31, 2024 |  |  | December 31, 2023 |  |  | Change |
Contract assets | $ | 188,941 |  |  | $ | 201,832 |  |  | $ | (12,891 | )
Contract liabilities |  | (24,580 | ) |  |  | (21,997 | ) |  |  | (2,583 | )
Net contract assets (liabilities) | $ | 164,361 |  |  | $ | 179,835 |  |  | $ | (15,474 | )
The net contract assets (liabilities) as of December 31, 2024 decreased by $15.5 million as compared to December 31, 2023, primarily due to the timing difference between the performance of services and billings to and payments from customers. There were no material changes to contract balances due to impairments or credit losses during the period. During the years ended December 31, 2024 and 2023, the Company recognized $17.6 million and $17.8 million in revenue related to the contract liabilities balance at December 31, 2023 and 2022, respectively.
