In addition, we revised the financial information our chief operating decision maker, or decision-making group (our “CODM”), regularly reviews to allocate resources and assess our performance. This change is consistent with our new strategic plan and better aligns with our continuing civil construction and materials business.

The contractual consideration from customers of our Construction segment may not one Subsequent to the inception of a contract in our Construction segment, the transaction price could change for various reasons, including executed or unapproved change orders, and unresolved contract modifications and/or affirmative claims. Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis at contract inception. Otherwise, changes are accounted for as separate performance obligation(s) and the separate transaction price is allocated as discussed above. Changes are made to the transaction price from unapproved change orders to the extent the amount can be reasonably estimated and recovery is probable. On certain projects we have submitted and have pending unresolved contract modifications and/or affirmative claims (“affirmative claims”) to recover additional costs and the associated profit, if applicable, to which the Company believes it is entitled under the terms of contracts with customers, subcontractors, vendors or others. The owners or their authorized representatives and/or other third may may Changes are made to the transaction price from affirmative claims with customers to the extent that additional revenue on a claim settlement with a customer is probable and estimable. A reduction to costs related to affirmative claims with non-customers with whom we have a contractual arrangement (“back charges”) is recognized when the estimated recovery is probable and estimable. Recognizing affirmative claims and back charge recoveries requires significant judgments of certain factors including, but not Generally, performance obligations related to contracts in our Construction segment are satisfied over time because our performance typically creates or enhances an asset that the customer controls as the asset is created or enhanced. We recognize revenue as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer. Revenue in our Construction segment is ordinarily recognized over time as control is transferred to the customers by measuring the progress toward complete satisfaction of the performance obligation(s) using an input (i.e., “cost to cost”) method. Under the cost to cost method, costs incurred to-date are generally the best depiction of transfer of control. All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the forecasted revenue and cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach. There are a number of factors that can contribute to revisions in estimates of contract cost and profitability. The most significant of these include: • changes in costs of labor and/or materials; • subcontractor costs, availability and/or performance issues; • extended overhead and other costs due to owner, weather and other delays; • changes in productivity expectations; • changes from original design on design-build projects; • our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; • a change in the availability and proximity of equipment and materials; • complexity in original design; • length of time to complete the project; • the availability and skill level of workers in the geographic location of the project; • site conditions that differ from those assumed in the original bid; • costs associated with scope changes; and • the customer’s ability to properly administer the contract. The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins may All state and federal government contracts and many of our other contracts provide for termination of the contract at the convenience of the party contracting with us, with provisions to pay us for work performed through the date of termination including demobilization cost.

Recognize revenue Generally, our contracts contain one may not The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring goods and services to the customer. The contractual consideration from customers of our Construction segment may not one Subsequent to the inception of a contract in our Construction segment, the transaction price could change for various reasons, including executed or unapproved change orders, and unresolved contract modifications and/or affirmative claims. Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis at contract inception. Otherwise, changes are accounted for as separate performance obligation(s) and the separate transaction price is allocated as discussed above. Changes are made to the transaction price from unapproved change orders to the extent the amount can be reasonably estimated and recovery is probable. On certain projects we have submitted and have pending unresolved contract modifications and/or affirmative claims (“affirmative claims”) to recover additional costs and the associated profit, if applicable, to which the Company believes it is entitled under the terms of contracts with customers, subcontractors, vendors or others. The owners or their authorized representatives and/or other third may may Changes are made to the transaction price from affirmative claims with customers to the extent that additional revenue on a claim settlement with a customer is probable and estimable. A reduction to costs related to affirmative claims with non-customers with whom we have a contractual arrangement (“back charges”) is recognized when the estimated recovery is probable and estimable. Recognizing affirmative claims and back charge recoveries requires significant judgments of certain factors including, but not Generally, performance obligations related to contracts in our Construction segment are satisfied over time because our performance typically creates or enhances an asset that the customer controls as the asset is created or enhanced. We recognize revenue as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer. Revenue in our Construction segment is ordinarily recognized over time as control is transferred to the customers by measuring the progress toward complete satisfaction of the performance obligation(s) using an input (i.e., “cost to cost”) method. Under the cost to cost method, costs incurred to-date are generally the best depiction of transfer of control. All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the forecasted revenue and cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach. There are a number of factors that can contribute to revisions in estimates of contract cost and profitability. The most significant of these include: • changes in costs of labor and/or materials; • subcontractor costs, availability and/or performance issues; • extended overhead and other costs due to owner, weather and other delays; • changes in productivity expectations; • changes from original design on design-build projects; • our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; • a change in the availability and proximity of equipment and materials; • complexity in original design; • length of time to complete the project; • the availability and skill level of workers in the geographic location of the project; • site conditions that differ from those assumed in the original bid; • costs associated with scope changes; and • the customer’s ability to properly administer the contract. The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins may All state and federal government contracts and many of our other contracts provide for termination of the contract at the convenience of the party contracting with us, with provisions to pay us for work performed through the date of termination including demobilization cost.

[1]	During 2020 the interim goodwill impairment tests resulted in impairment charges. See further discussion in note (1) in the statements of operations table within this footnote.
[2]	During 2020, we performed two interim goodwill impairment tests. The first was on the WMS Materials and WMS Specialty reporting units due to an adverse change in the business climate for these reporting units, including a modified relationship with a business partner, increased competition and market consolidation, exacerbated by economic disruption and market conditions associated with the COVID-19 pandemic. The goodwill impairment test resulted in a $14.8 million impairment charge during the three months ended March 31, 2020 associated with the WMS Materials reporting unit and no impairment charge related to the WMS Specialty reporting unit. The second test was on the WMS Water and WMS Materials reporting units due to the continued impact from an adverse change in the business climate, including reduced market share due to loss of strategic personnel during the three months ended September 30, 2020. The goodwill impairment test resulted in an additional impairment charge of $117.9 million and $14.4 million associated with our WMS Water and WMS Materials reporting units, respectively, during the three months ended September 30, 2020. In addition, we recorded an impairment charge of $9.6 million during the year ended December 31, 2020 related to entities within investments in foreign affiliates related due to other than temporary adverse changes in the associated business climate.
[3]	During 2021, we completed a sale-leaseback transaction for two properties in California. The sale of these properties resulted in a reduction in net property and equipment of $11.1 million and a $2.4 million addition to both right of use assets and lease liabilities on the held-for-sale balance sheets, as well as a $29.7 million gain on sales of property and equipment on the discontinued operations statements of operations.

[1]	Due to the net losses from continuing operations for the years ended December 31, 2021 and 2019, RSUs representing approximately 533,000 and 388,000 shares, respectively, have been excluded from the number of shares used in calculating diluted net income (loss) per share, as their inclusion would be antidilutive.
[2]	The number of shares used in calculating diluted net income (loss) per share for the year ended December 31, 2021 excluded the potential dilution from the 2.75% Convertible Notes converting into shares of common stock due to the net loss from continuing operations for the period. The number of shares used in calculating diluted net income per share for the years ended December 31, 2020 and 2019 excluded potential dilution from the 2.75% Convertible Notes converting into shares of common stock since the average stock price did not exceed $31.47.
