Contract Balances

The following table provides information about receivables, contract assets, and contract liabilities from contracts with customers as of June 28, 2019:

	June 28, 2019	December 31, 2018

Receivables reported as accounts receivable, net	$ 2,452	$ 3,250
Contract revenue in excess of billings	3,705	3,484
Billings in excess of contract revenue	3,713	5,959

Significant changes in the contract assets and the contract liabilities balances during the period are as follows:

	Contract Assets	Contract Liabilities

Revenue recognized that was included in the contract liability balance at the beginning of the period		$ (3,887)

Increases due to amounts billed to customers, excluding amounts recognized as revenue during the period		$ 1,641

Transferred to receivables from contract assets recognized at the beginning of the period	$ (2,656)

Increases as a result of revenue recognized, excluding amounts transferred to receivables during the period	$ 2,877

Contract assets arise when revenue recognized on a contract exceeds the cumulative progress billings. Contracts generally provide for an enforceable right to payment for performance completed to date but do not necessarily have a present right to consideration payment for performance completed until the event that triggers the progress billing. The contract assets are transferred to the receivables when the rights to payment occur and amounts are billed. Contract liabilities arise when progress billings on a contract exceed the revenue recognized. Contract liabilities are relieved as the performance obligation is completed and revenue is recognized. Progress billings vary among contracts and can be triggered by chronological milestones, performance events or other various measurements of performance.

Backlog of Remaining Customer Performance Obligations

The following table includes estimated revenue expected to be recognized and recorded as sales in the future from the backlog of performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period.
