RECEIVABLES

Receivables were comprised of the following:

	December 31,
(In thousands)	2020		2019
Billed receivables	$	102,045	$	71,068
Unbilled receivables (contract assets)	203,127		186,365
Other	9,787		11,711
Total Receivables	$	314,959	$	269,144

As of December 31, 2020 and 2019, substantially all billed receivables are due from the U.S. government, either directly as prime contractor to the U.S. government or as subcontractor to another prime contractor to the U.S. government. Because the Company’s billed receivables are with the U.S. government, the Company does not believe it has a material credit risk exposure.

Unbilled receivables are contract assets that represent revenue recognized on long-term contracts in excess of amounts billed as of the balance sheet date. We expect to bill customers for the majority of the December 31, 2020 contract assets during 2021. Changes in the balance of receivables are primarily due to the timing differences between our performance and customer payments.
