NOTE 4—ACCOUNTS RECEIVABLE

The components of accounts receivable under long-term contracts are as follows (in thousands):

September 30,	2017		2016
U.S. Government Contracts:
Amounts billed	$	76,451	$	66,668
Recoverable costs and accrued profits on progress completed--not billed		88,105		81,624
		164,556		148,292
Commercial Customers:
Amounts billed		119,041		79,955
Recoverable costs and accrued profits on progress completed--not billed		150,668		160,098
		269,709		240,053
		434,265		388,345
Less unbilled amounts not currently due--commercial customers		(17,457)		(20,926)
	$	416,808	$	367,419

A portion of recoverable costs and accrued profits on progress completed is billable under progress or milestone payment provisions of the related contracts. The remainder of these amounts is billable upon delivery of products or furnishing of services, with an immaterial amount subject to retainage provisions of the contracts. It is anticipated that we will bill and collect substantially the entire unbilled portion of receivables identified as current assets under progress billing provisions of the contracts or upon completion of milestones and/or acceptance by the customers during fiscal 2018. The amount classified as not currently due is an estimate of the amount of long-term contract accounts receivable that will not be collected within one year from September 30, 2017 under transportation systems contracts in the U.S. and Australia, and under a CGD Systems contract in Italy based upon the payment terms in the contracts.
