Revenue for unsatisfied performance obligations expected to be recognized in the future for contracts with an original expected duration of greater than one year was de minimis as of June 30, 2022 and $6.6 million as of December 31, 2021. These amounts do not include contracts with an original expected duration of less than one year, which is the majority of the Company’s contracts. The decrease from the prior-year end was primarily due to an agreement modification whereby the Company agreed to a $6.2 million cash settlement with one of its customers in exchange for the full, final and immediate termination of certain deferred revenue liabilities. The remaining decrease was due to the recognition of revenue during the normal course of business.

Remaining deferred revenue that is anticipated to be recognized during the succeeding 12-month period is recorded in the current portion of deferred revenue within the condensed consolidated balance sheets.
