Contract Balances

The Company records contract assets when it has a right to consideration and records accounts receivable when it has an unconditional right to consideration. Contract liabilities consist of cash payments received (or unconditional rights to receive cash) in advance of fulfilling performance obligations. As of December 31, 2021 and 2020, the Company did not have a material contract assets balance.

The following table is a summary of the Company’s opening and closing balances of contract liabilities related to contracts with customers.

(Amounts in thousands)	Total
Balance at December 31, 2019	$	303
Increase		561
Balance at December 31, 2020	$	864
Increase		3,061
Balance at December 31, 2021	$	3,925

The increase in contract liabilities during the year ended December 31, 2021 and 2020 was primarily due to invoiced amounts that did not yet meet the revenue recognition criteria, which for the year ended December 31, 2020, was partially offset by the revenue recognition criteria being met for previously deferred revenue. The amount of revenue recognized for the year ended December 31, 2021 and 2020 that was included in the prior period contract liability balance was approximately $864 thousand and $150 thousand. This revenue consisted of services provided to customers who had been invoiced prior to the year ended December 31, 2021.
