Contract Assets and Liabilities

Contract Assets and LiabilitiesContracts with customers usually stipulate the timing of payment, which is defined by the terms found within the various contracts under which work was performed during the period. Therefore, contract assets and liabilities are created when the timing of costs incurred on work performed does not coincide with the billing terms, which frequently include retention provisions contained in each contract.

The Company’s consolidated balance sheets present contract assets, which contain unbilled revenue and contract retainages associated with contract work that has been completed and billed but not paid by customers, pursuant to retainage provisions, that are generally due once the job is completed and approved. The allowance for doubtful accounts associated with contract assets was $0.4 million as of December 31, 2021 and 2020.

Contract assets consisted of the following at December 31:

(in thousands)	2021		2020		Change
Unbilled revenue, net	$	134,187	$	97,543	$	36,644
Contract retainages, net	90,888		88,260		2,628
Contract assets, net	$	225,075	$	185,803	$	39,272

The Company’s consolidated balance sheets present contract liabilities which contain deferred revenue and an accrual for contracts in a loss provision.

Contract liabilities consisted of the following at December 31:

(in thousands)	2021		2020		Change
Deferred revenue	$	165,699	$	155,570	$	10,129
Accrued loss provision	2,232		2,826		(594)
Contract liabilities	$	167,931	$	158,396	$	9,535

The following table provides information about contract assets and contract liabilities from contracts with customers at December 31:

(in thousands)	2021		2020		Change
Contract assets	$	225,075	$	185,803	$	39,272
Contract liabilities	(167,931)		(158,396)		(9,535)
Net contract assets (liabilities)	$	57,144	$	27,407	$	29,737

The difference between the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing of the Company’s billings in relation to its performance of work. The amounts of revenues recognized in the period that were included in the opening contract liability balances were $116.5 million and $72.2 million for the year ended December 31, 2021 and 2020, respectively. This revenue consists primarily of work performed on previous billings to customers.

The net asset position for contracts in process consisted of the following at December 31:

(in thousands)	2021		2020
Costs and estimated earnings on uncompleted contracts	$	4,130,621	$	3,921,376
Less: billings to date	4,162,133		3,979,403
