Remaining performance obligations. As permitted by ASC 606, Revenue from Contracts with Customers, we have elected not to disclose information about remaining performance obligations where (i) the performance obligation is part of a contract that has an original expected duration of one year or less or (ii) when we recognize revenue from the satisfaction of the performance obligation in accordance with the right-to-invoice practical expedient, which permits us to recognize revenue in the amount to which we have a right to invoice the customer if that amount corresponds directly with the value to the customer of our performance completed to date. As most of our contracts with customers are short-term in nature and billed on a time and material basis, there were no material amounts of remaining performance obligations as of June 30, 2024 and December 31, 2023.
