Remaining performance obligations

A significant number of the Company’s product and service sales are short-term in nature with a contract term of one year or less. For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

As of December 31, 2022, the aggregate amount of remaining performance obligations that were unsatisfied or partially unsatisfied related to customer contracts was $1.8 million. This amount included deferred revenue on the

Company’s consolidated balance sheets, of which approximately 99% is expected to be recognized to revenue in the next 12 months.

As of December 31, 2021, the aggregate amount of remaining performance obligations related to customer contracts that are unsatisfied or partially unsatisfied was $2.7 million which included deferred revenue on the Company’s consolidated balance sheets, of which approximately 98% was expected to be recognized to revenue in the next 12 months.
