Revenue Recognition	Revenue Recognition. All of our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically, ranging from weekly to monthly. We use the input method to recognize revenue, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. When appropriate, we apply the practical expedient to recognize revenue for the amount invoiced when the invoice corresponds directly to the value of our performance to date. We account for significant fixed-price contracts, mainly relating to our Manufactured Products segment, and to a lesser extent in our Offshore Projects Group (“OPG”) and Aerospace and Defense Technologies (“ADTech”) segments, by recognizing revenue over time using the cost-to-cost input method. The performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. In 2024, 2023 and 2022, we accounted for 19%, 19% and 15%, respectively, of our revenue using the cost-to-cost input method to measure progress toward satisfying the related performance obligations on our contracts. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation. We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, and that are collected by us from customers, are excluded from revenue. In our service-based business lines, we principally charge on a dayrate basis for services provided. In our product-based business lines, predominantly in our Manufactured Products segment, we recognize revenue and profit using the percentage-of-completion method and exclude uninstalled materials and significant inefficiencies from the measure of progress. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, we apply judgment, when applicable, in the determination and allocation of transaction price to performance obligations and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, when required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. During the year ended December 31, 2024, we recognized projected losses of $13 million for contracts in our Manufactured Products segment. During the year ended December 31, 2023, we recognized a projected loss of $9.8 million for contracts in our Manufactured Products segment. During the year ended December 31, 2022, we recognized a projected loss of $5.2 million for contracts in our Manufactured Products segment. There could be adjustments to overall contract costs in the future, due to changes in facts and circumstances. In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms. See Note 3—“Revenue” for more information on our revenue from contracts with customers.
