NOTE C—CONTRACT RECEIVABLES

Contract receivables consisted of the following at December 31:

	2013			2012
Billed	$	102,995		$	133,014
Unbilled		96,243			66,814
Retainages		3,914			3,654
Other		3,663			2,904
Allowance for doubtful accounts		(1,753	)		(1,448	)
Contract receivables, net	$	205,062		$	204,938

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 decrease in billed receivables and the increase in unbilled receivables are primarily due to fewer days in the related billing cycles at December 31, 2013 compared to December 31, 2012. 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.
