RECEIVABLES

Receivables primarily include amounts billed to customers, unbilled charges on long-term contracts consisting of amounts recognized as sales but not billed, and other receivables. Substantially all amounts of unbilled receivables are expected to be billed and collected within one year. An immaterial amount of unbilled receivables are subject to retainage provisions. The amount of claims and unapproved change orders within our receivables balances are immaterial.
