Revenue Recognition: The Company provides construction, maintenance and support services to customers in energy, power and industrial end markets. The Companys services, which are provided through long-term maintenance or discrete project agreements, are designed to improve or sustain its customers operating efficiencies and extend the useful lives of their process equipment. The contracts are awarded on a competitively bid and negotiated basis with the majority structured as cost-plus arrangements and the remainder as lump-sum. The Companys contracts generally include a single performance obligation for which revenue is recognized over time, as performance obligations are satisfied, due to the continuous transfer of control to the customer. For cost-plus contracts, the Company recognizes revenue when services are performed and contractually billable based upon the hours incurred and agreed-upon hourly rates. Revenue on fixed-price contracts is recognized and invoiced over time using the cost-to-cost percentage-of-completion method. To the extent a contract is deemed to have multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. The Company does not adjust the price of the contract for the effects of a significant financing component. Change orders are generally not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. The Company believes these methods of revenue recognition most accurately reflect the economics of the transactions with its customers. The Companys contracts may include several types of variable consideration, including change orders, rate true-up provisions, retainage, claims, incentives, penalties and liquidated damages. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the amount of consideration to which the Company expects to be entitled. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Companys estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. In circumstances where the Company cannot reasonably determine the outcome of a contract, it recognizes revenue over time as the work is performed, but only to the extent of recoverable costs incurred (i.e. zero margin). A loss provision is recorded for the amount of any estimated unrecoverable costs in excess of total estimated revenue on a contract as soon as the Company becomes aware. The Company generally provides a limited warranty for a term of two years or less following completion of services performed under its contracts. Historically, warranty claims have not resulted in material costs incurred.
