Contract with Customer, Asset and Liability [Table Text Block]

Contract Assets

The Company’s contract assets consist of un-billed amounts resulting from contracts for which revenue is recognized over time using the cost-to-cost method, and for which revenue recognized exceeds the amount billed to the customer.

Activity related to contract assets, which are included in other current assets on the consolidated balance sheet, is as follows:

	June 30, 2020		June 30, 2019		$ Change			% Change
Contract assets	$	8,435	$	8,920	$	(485	)	(5.4	)%

The difference between the opening and closing balances of the Company's contract assets primarily results from the timing difference between the Company's performance and when the customer is billed.
