NOTE C—CONTRACT RECEIVABLES

Contract receivables consisted of the following at December 31: 

	2014			2013
Billed	$	162,976		$	102,995
Unbilled		90,419			96,243
Retainages		5,788			3,914
Other		2,958			3,663
Allowance for doubtful accounts		(1,887	)		(1,753	)
Contract receivables, net	$	260,254		$	205,062

Contract receivables, net of the established allowance, are stated at amounts expected to be realized in future periods. Unbilled receivables result from revenue that has been earned in advance of billing. Unbilled receivables can be invoiced at contractually defined intervals or milestones, as well as upon completion of the contract or government audits. The increase in billed receivables is primarily due to the recent acquisitions of Olson, Mostra and CityTech and the decrease in unbilled receivables is primarily due to the number of days in the related billing cycles at December 31, 2014 compared to December 31, 2013. The Company anticipates that the majority of unbilled receivables will be substantially billed and collected within one year, and therefore, classifies them as current assets in accordance with industry practice.
