The Company’s accounting for revenues on contracts with customers is based on a single comprehensive five-step model that requires reporting entities to:

The Company focuses on the transfer of the contractor’s control of the goods and/or services to the customer, as opposed to the transfer of risk and rewards. Major provisions of the current guidance cover the determination of which goods and services are distinct and represent separate performance obligations, the appropriate treatments for variable consideration, and the evaluation of whether revenues should be recognized at a point in time or over time.

When a performance obligation is satisfied over time, the related revenues are recognized over time. The Company’s revenues are recognized primarily under various types of long-term construction contracts, including those for which revenues are based on either a fixed-price or a time-and-materials basis, and primarily over time as performance obligations are satisfied due to the continuous transfer of control to the project owner or other customer.

Revenues from fixed-price contracts, including portions of estimated gross profit, are recognized as services are provided, based on costs incurred and estimated total contract costs using the cost-to-cost approach. If, at any time, the estimate of contract profitability indicates an anticipated loss on a contract, the Company will recognize the total loss in the reporting period in which it is identified and the loss amount becomes estimable. Revenues from time-and-materials contracts are recognized when the related services are provided to the customer.

Almost all of the Company’s fixed-price contracts are considered to have a single performance obligation. Although multiple promises to transfer individual goods or services may exist, they are not typically distinct within the context of such contracts because contract promises included therein are interrelated or the contracts require the Company to perform critical integration so that the customer receives a completed project. Warranties provided under the Company’s contracts with customers are assurance-type and are recorded as the corresponding contract work is performed.

The transaction price for a contract represents the value of the contract awarded to the Company that is used to determine the amount of revenues recognized as of the balance sheet date. It may reflect amounts of variable consideration which could be either increases or decreases to the transaction price. These adjustments can be made from time-to-time during the period of contract performance as circumstances evolve related to such items as changes in the scope and price of contracts, claims, incentives and liquidated damages.

Contract assets include amounts that represent the rights to receive payment for goods or services that have been transferred to the project owner, with the rights conditional upon something other than the passage of time. Contract liabilities include amounts that reflect obligations to provide goods or services for which payment has been received. Contract retentions are billed amounts which, pursuant to the terms of the applicable contract, are not paid by project owners until a defined phase of a contract or project has been completed and accepted. These retained amounts are reflected in contract assets or contract liabilities depending on the net contract position of the particular contract. Retention amounts and the length of retention periods may vary. Retainage amounts related to active contracts are considered current regardless of the term of the applicable contract; such amounts are generally collected by the completion of the applicable contract. The total of amounts retained by project owners under construction contracts at October 31, 2021 and January 31, 2021 were $41.3 million and $36.8 million, respectively.

Variable Consideration

Amounts for contract variations for which the Company has project-owner directive for additional work or other scope change, but not for the price associated with the corresponding additional effort, are included in the transaction price when it is considered probable that the applicable costs will be recovered through a modification to the contract price. The effects of any revision to a transaction price can be determined at any time and they could be material. The Company may include in the corresponding transaction price a portion of the amount claimed in a dispute that it expects to receive from a project owner. Once a settlement of the dispute has been reached with the project owner, the transaction price may be revised again to reflect the final resolution. The aggregate amount of such contract variations included in the transaction prices that were used to determine project-to-date revenues at October 31, 2021 and January 31, 2021 were $6.8 million and $16.6 million, respectively. Variations related to the Company’s contracts typically represent modifications to the existing contracts and performance obligations, and do not represent new performance obligations. Actual costs related to any changes in the scope of the corresponding contract are expensed as they are incurred. Changes to total estimated contract costs and losses, if any, are reflected in operating results for the period in which they are determined.

The Company’s long-term contracts typically have schedule dates and other performance objectives that if not achieved could subject the Company to liquidated damages. These contract requirements generally relate to specified activities that must be completed by an established date or by the achievement of a specified level of output or efficiency. Each applicable contract defines the conditions under which a project owner may be entitled to any liquidated damages. At the outset of each of the Company’s contracts, the potential amounts of liquidated damages typically are not subtracted from the transaction price as the Company believes that it has included activities in its contract plan, and the associated costs, that

will be effective in preventing such damages. Of course, circumstances may change as the Company executes the corresponding contract. The transaction price is reduced by an applicable amount when the Company no longer considers it probable that a future reversal of revenues will not occur when the matter is resolved. The Company considers potential liquidated damages, the costs of other related items and potential mitigating factors in determining the adequacy of its regularly updated estimates of the amounts of gross profit expected to be earned on active projects.

In other cases, the Company may have the grounds to assert liquidated damages against subcontractors, suppliers, project owners or other parties related to a project. Such circumstances may arise when the Company’s activities and progress are adversely affected by delayed or damaged materials, challenges with equipment performance or other events out of the Company’s control where the Company has rights to recourse, typically in the form of liquidated damages. In general, the Company does not adjust the corresponding contract accounting until it is probable that the favorable cost relief will be realized. Such adjustments have been and could be material.

The Company records adjustments to revenues and profits on contracts, including those associated with contract variations and estimated cost changes, using a cumulative catch-up method. Under this method, the impact of an adjustment to the amount of revenues recognized to date is recorded in the period that the adjustment is identified. Estimated variable consideration amounts are determined by the Company based primarily on the single most likely amount in the range of possible consideration amounts. Revenues and profits in future periods of contract performance are recognized using the adjusted amounts of transaction price and estimated contract costs.

Accounting for the Subcontract Loss

Construction activities that were performed by APC on the mechanical installation of the boiler for a biomass-fired power plant under construction in Teesside, England, the Tees Renewable Energy Plant (“TeesREP”), were suspended in March 2020 due to the COVID-19 pandemic, pending preparations being made by the contractors and subcontractors to comply with new and evolving government guidance concerning public health protocols. At the time of the suspension of work on the TeesREP project, APC had completed approximately 90% of its subcontracted work.

APC entered into an amendment to the subcontract with its customer, effective June 1, 2020, covering the various terms and conditions for completion of the installation of the boiler. The agreement represented a global settlement of past commercial differences with both parties making significant concessions, and converted the billing arrangements for the remaining work to a time-and-materials basis. During October 2020, APC and its customer agreed to additional contractual changes that effectively recognized APC’s completion of the single performance obligation and that established a time-and-materials contractual arrangement covering any additional works requested by APC’s customer until completion of APC’s engagement which occurred during the current year.

The accounting for the subcontract, as amended, resulted in reductions to the subcontract loss that were recorded during the three and nine months ended October 31, 2020, in the approximate amounts of $2.8 million and $4.1 million, respectively. Accordingly, the final amount of the TeesREP subcontract loss was $29.5 million, and the remaining subcontract loss reserve balance was eliminated as of October 31, 2020. The total amounts of accounts receivable and contract assets related to the TeesREP project and included in the condensed consolidated balance sheets were less than $0.1 million as of October 31, 2021 and were $4.7 million as of January 31, 2021.

Remaining Unsatisfied Performance Obligations (“RUPO”)

The amount of RUPO represents the unrecognized revenue value of active contracts with customers as determined under the revenue recognition rules of US GAAP. Increases to RUPO during a reporting period represent the transaction prices associated with new contracts, as well as additions to the transaction prices of existing contracts. The amounts of such changes may vary significantly each reporting period based on the timing of major new contract awards and the occurrence and assessment of contract variations.

At October 31, 2021, the Company had RUPO of $491.6 million. The largest portion of RUPO at any date usually relates to EPC service contracts with typical performance durations of one to three years. However, the length of certain significant construction projects may exceed three years. The Company estimates that approximately 25% of the RUPO amount at October 31, 2021 will be included in the amount of consolidated revenues that will be recognized during the remainder of the fiscal year ending January 31, 2022. Most of the remaining amount of RUPO at October 31, 2021 is expected to be recognized in revenues during the fiscal year ending January 31, 2023.

Revenues for future periods will also include amounts related to customer contracts awarded subsequent to October 31, 2021. It is important to note that estimates may be changed in the future and that cancellations, deferrals or scope adjustments may occur related to work included in the amount of RUPO at October 31, 2021. Accordingly, RUPO may be adjusted to reflect project delays and cancellations, revisions to project scope and cost and foreign currency exchange fluctuations, or to revise estimates, as effects become known. Such adjustments may materially reduce future revenues below Company estimates.
