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 faithfully depict revenue recognition, 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 an input, cost-to-cost measurement percentage-of-completion method. In 2021, 2020 and 2019, we accounted for 16%, 24% and 21%, respectively, of our revenue using the input, cost-to-cost measurement percentage-of-completion method. This commonly used method allows appropriate calculation of progress on our contracts. A performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. 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. 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. We did not have any material adjustments to earnings as a result of revisions to contract estimates during the years ended December 31, 2021, 2020 and 2019. However, there could be significant 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.
