Accounting Policies [Abstract] |
Basis of Presentation | (a) Basis of Presentation The accompanying consolidated financial statements have been prepared in compliance with generally accepted accounting principles in the United States (“GAAP”) as codified in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”). Certain amounts in the consolidated financial statements and notes thereto of prior years have been reclassified to conform to the current year presentation.
Principles of Consolidation | (b) Principles of Consolidation The consolidated financial statements include the accounts of Tutor Perini Corporation and its wholly owned subsidiaries (the “Company”). The Company occasionally forms joint ventures with outside parties for the execution of single contracts or projects. The Company assesses its joint ventures to determine if they meet the qualifications of a variable interest entity (“VIE”) in accordance with ASC 810, Consolidation (“ASC 810”). If a joint venture is a VIE and the Company is the primary beneficiary, the joint venture is fully consolidated (see Note 13). If a joint venture is not a VIE, it may be consolidated under the voting interest method if the Company holds a controlling financial interest in the joint venture. The Company is considered to hold a controlling financial interest when it is able to exercise control over the joint venture’s operating and financial decisions. For construction joint ventures that do not need to be consolidated but qualify for the equity method of accounting, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated financial statements. Intercompany balances and transactions have been eliminated.
Use of Estimates | (c) Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect reported amounts. These estimates are based on information available through the date of the issuance of the financial statements; therefore, actual results could differ from those estimates.
Revenues | (d) Revenues Revenue Recognition The Company derives revenue from long-term construction contracts with public and private customers primarily in the United States and its territories and in certain other international locations. The Company’s construction contracts are generally each accounted for as a single unit of account (i.e., as a single performance obligation). Throughout the execution of construction contracts, the Company and its affiliated entities recognize revenue with the continuous transfer of control to the customer. The customer typically controls the asset under construction by either contractual termination clauses or by the Company’s rights to payment for work already performed on the asset under construction that does not have an alternative use for the Company. Because control transfers over time, revenue is recognized to the extent of progress towards completion of the performance obligations. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services provided. The Company generally uses the cost-to-cost method for its contracts, which measures progress towards completion for each performance obligation based on the ratio of costs incurred to date to the total estimated costs at completion for the respective performance obligation. Incurred cost represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Revenue, including estimated fees or profits, is recorded proportionately as costs are incurred. Cost of operations includes labor, materials, subcontractor costs, and other direct and indirect costs, including depreciation and amortization. Due to the nature of the work required to be performed on many of the Company’s performance obligations, estimating total revenue and cost at completion is complex, subject to many variables and requires significant judgment. Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration, including the impact of change orders, claims, contract disputes and the achievement of contractual performance criteria, and award or other incentive fees are made during the contract performance period. The Company estimates variable consideration at the most likely amount it expects to receive. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to management. Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above for variable consideration have been satisfied. Changes in Estimates on Construction Contracts The Company’s estimates of contract revenue and cost are highly detailed and many factors change during a contract performance period that result in a change to contract profitability. These factors include, but are not limited to, differing site conditions; availability of skilled contract labor; performance of major material suppliers and subcontractors; on-going subcontractor negotiations and buyout provisions; unusual weather conditions; changes in the timing of scheduled work; change orders; accuracy of the original bid estimate; changes in estimated labor productivity and costs based on experience to date; achievement of incentive-based income targets; and the expected, or actual, resolution terms for claims. The factors that cause changes in estimates vary depending on the maturation of the project within its lifecycle. For example, in the ramp-up phase, these factors typically consist of revisions in anticipated project costs and during the peak and closeout phases, these factors include the impact of change orders and claims, as well as additional revisions in remaining anticipated project costs. Generally, if the contract is at an early stage of completion, the current period impact is smaller than if the same change in estimate is made to the contract at a later stage of completion. Management evaluates changes in estimates on a contract-by-contract basis and discloses significant changes, if material, in the Notes to Consolidated Financial Statements. The cumulative catch-up method is used to account for revisions in estimates.
Retention Receivable and Payable | (e) Retention Receivable and Payable Retention receivable represents amounts invoiced to customers representing an unconditional right to cash where payments have been partially withheld pending the completion of certain milestones, satisfaction of other contractual conditions or the completion of the project. Retention agreements vary from project to project, and balances could be outstanding for several months or years depending on a number of circumstances, such as contract-specific terms, project performance and other variables that may arise as the Company makes progress toward completion. Retention payable represents amounts invoiced to the Company by subcontractors where payments have been partially withheld pending the completion of certain milestones, other contractual conditions or upon the completion of the project. Generally, retention payable is not remitted to subcontractors until the associated retention receivable from customers is collected.
Capitalized Contract Costs | (f) Capitalized Contract Costs Capitalized contract costs are included in other current assets and primarily represent costs to fulfill a contract that (1) directly relate to an existing or anticipated contract, (2) generate or enhance resources that will be used in satisfying performance obligations in the future and (3) are expected to be recovered through the contract. Capitalized contract costs are generally expensed to the associated contract over the period of anticipated use on the project.
Depreciation of Property and Equipment and Amortization of Long-Lived Intangible Assets | (g) Depreciation of Property and Equipment and Amortization of Long-Lived Intangible Assets Property and equipment and long-lived intangible assets are generally depreciated or amortized on a straight-line basis over their estimated useful lives ranging from three to forty years.
Recoverability of Long-Lived Assets | (h) Recoverability of Long-Lived Assets Long-lived assets are reviewed for impairment whenever circumstances indicate that the future cash flows generated by the assets might be less than the assets’ net carrying value. In such circumstances, an impairment loss will be recognized by the amount the assets’ net carrying value exceeds their fair value.
Recoverability of Goodwill | (i) Recoverability of Goodwill The Company tests goodwill for impairment annually as of October 1 for each reporting unit and between annual tests if events occur or circumstances change which suggest that goodwill should be reevaluated. Such events or circumstances include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, among other factors. The Civil, Building and Specialty Contractors segments each represent a reporting unit, and the Civil reporting unit carried the remaining goodwill balance at December 31, 2024. The Company performs its annual quantitative impairment assessment during the fourth quarter of each year using a weighted average of an income and a market approach. These approaches utilize various valuation assumptions, and small changes to the assumptions could have a significant impact on the concluded fair value. The income approach is based on the estimated present value of future cash flows for each reporting unit carrying a goodwill balance. The market approach is based on assumptions about how market data relates to each reporting unit carrying a goodwill balance. The weighting of these two approaches is based on their individual correlation to the economics of each reporting unit carrying a goodwill balance. The annual quantitative assessment performed in the fourth quarter of 2024 resulted in an estimated fair value that exceeded the net book value of the Civil reporting unit; therefore, no impairment charge was necessary.
Recoverability of Non-Amortizable Trade Names | (j) Recoverability of Non-Amortizable Trade Names Certain trade names have an estimated indefinite life and are not amortized to earnings, but instead are reviewed for impairment annually, or more often if events occur or circumstances change which suggest that the non-amortizable trade names should be reevaluated. The Company performs its annual quantitative impairment assessment during the fourth quarter of each year using an income approach (relief from royalty method). The assessment performed in the fourth quarter of 2024 resulted in an estimated fair value for the non-amortizable trade names that exceeded their respective net book values; therefore, no impairment charge was necessary.
Income Taxes | (k) Income Taxes Deferred income tax assets and liabilities are recognized for the effects of temporary differences between the financial statement carrying amounts and the income tax basis of assets and liabilities using tax rates expected to be in effect when such differences reverse. Income tax positions must meet a more-likely-than-not threshold to be recognized. The Company recognizes interest and penalties related to uncertain tax positions as a component of the income tax provision.
Earnings Per Common Share | (l) Earnings Per Common Share Basic earnings per common share (“EPS”) and diluted EPS are calculated by dividing net income (loss) attributable to Tutor Perini Corporation by the following: for basic EPS, the weighted-average number of common shares outstanding during the period; and for diluted EPS, the sum of the weighted-average number of both outstanding common shares and potentially dilutive securities, which for the Company can include restricted stock units (“RSUs”) and unexercised stock options. The Company calculates the effect of the potentially dilutive RSUs and stock options using the treasury stock method.
Cash, Cash Equivalents and Restricted Cash | (m) Cash, Cas h Equivalents and Restricted Cash The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets to the amounts shown in the Consolidated Statements of Cash Flows:
| As of December 31,
(in thousands) | 2024 | 2023
Cash and cash equivalents available for general corporate purposes | $ | 265,647 |  | $ | 145,055 |
Joint venture cash and cash equivalents | 189,437 |  | 235,509 |
Cash and cash equivalents | 455,084 |  | 380,564 |
Restricted cash | 9,104 |  | 14,116 |
Total cash, cash equivalents and restricted cash | $ | 464,188 |  | $ | 394,680 |
Cash equivalents include short-term, highly liquid investments with maturities of three months or less when acquired. Cash and cash equivalents consist of amounts available for the Company’s general purposes, the Company’s proportionate share of cash held by the Company’s unconsolidated joint ventures and 100% of amounts held by the Company’s consolidated joint ventures. In both cases, cash held by joint ventures is available only for joint venture-related uses, including future distributions to joint venture partners. Restricted cash includes amounts primarily held as collateral to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit.
Investments | (n) Investments The Company has investments consisting of 1) restricted investments primarily held as collateral to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit and insurance-related deposits; and 2) investments in lieu of retention. Investments in lieu of retention are recorded as a component of retention receivable on the accompanying Consolidated Balance Sheets. The Company’s investments consist primarily of debt securities classified as available-for-sale (“AFS”), consisting of U.S. government agency securities, municipal bonds and corporate debt securities that ar e rated A3 or better (s ee Note 12). The Company’s AFS debt securities are recorded at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss) (“AOCI”), net of applicable taxes. Realized gains and losses from sales of AFS debt securities are included in other income (expense) in our Consolidated Statements of Operations. Management evaluated the unrealized losses in AFS debt securities as of December 31, 2024 and 2023 to determine the existence of credit losses considering factors including credit ratings and other relevant information, which may indicate that contractual cash flows are not expected to occur. The results of this evaluation indicated that the unrealized losses on AFS debt securities are primarily attributable to market interest rate increases and not a deterioration in credit quality of the issuers. Based on the analysis, management determined that credit losses did not exist for AFS debt securities in an unrealized loss position as of December 31, 2024 and 2023. It is not considered likely that the Company will be required to sell the investments before full recovery of the amortized cost basis of the AFS debt securities, which may be at maturity. As a result, the Company has not recognized any impairment losses in earnings for the years ended December 31, 2024 and 2023.
Share-Based Compensation | (o) Share-Based Compensation The Company’s long-term incentive plans allow the Company to grant share-based compensation awards in a variety of forms, including RSUs, stock options, cash-settled performance stock units (“CPSUs”), cash-settled restricted stock awards (“CRSUs”), also known as deferred cash awards (“DCAs”), and unrestricted stock. RSUs give the holder the right to exchange their stock units for shares of the Company’s common stock on a one-for-one basis. These awards generally vest subject to service, performance or market conditions, with related compensation expense equal to the fair value of the award on the date of grant and recognized on a straight-line basis over the requisite period. The fair value of RSUs with service or performance-vesting conditions is generally based on the closing price of the Company’s common stock on the New York Stock Exchange (“NYSE”). Stock options give the holder the right to purchase shares of the Company’s common stock subsequent to the vesting date at a defined exercise price. A stock option exercise price must be equal to or greater than the fair value of the Company’s common stock on the date of the award. The term for stock options is limited to 10 years from the award date. Stock options generally vest subject to certain service, performance or market conditions, with related compensation expense equal to the fair value of the award on the date of grant and recognized on a straight-line basis over the requisite period. The fair value of stock options with service or performance-vesting conditions is generally based on the Black-Scholes model. CPSUs and CRSUs give the holder the right to exchange their stock units for cash based on the value of the Company’s common stock on the vesting date. CPSUs vest upon satisfaction of market or performance conditions and CRSUs vest subject to a service-based condition. CPSUs and CRSUs are classified as liability awards and are remeasured at fair value at the end of each reporting period with the change in fair value recognized in earnings. The fair value of CRSUs and performance-based CPSUs is generally based on the closing price of the Company’s common stock on the NYSE at the measurement date. The fair value of the performance-based CPSUs is also adjusted for expected achievement of performance conditions. Since CPSUs and CRSUs are settled in cash and no shares are issued, these awards do not dilute equity. Certain RSU, stock option and CPSU awards contain market condition components tied to the Company’s total shareholder return in relation to its peer companies, as calculated over a multi-year performance period (“TSR awards”). CPSU awards may also contain a market condition component tied to the annualized growth in price of the Company’s common stock over a multi-year performance period. The fair value of these market-based awards is estimated using a Monte Carlo simulation model. Significant assumptions used in this simulation model include the Company’s expected volatility, a risk-free rate based on U.S. Treasury yield curve rates with maturities consistent with the performance period, and, specifically pertaining to TSR awards, the volatilities for each of the Company’s peers. Unrestricted stock awards are fully vested upon issuance with related compensation expense equal to the fair value of the award on the date of grant. The fair value of unrestricted stock is based on the closing price of the Company’s common stock on the NYSE. For all awards with only a service-based vesting condition, the Company accounts for forfeitures upon occurrence, rather than estimating the probability of forfeiture at the date of grant. Accordingly, the Company recognizes the full grant-date fair value of these awards on a straight-line basis throughout the requisite service period, reversing any expense if, and only if, there is a forfeiture. For all awards that have a performance-based vesting condition, the Company evaluates the probability of achieving the performance criteria quarterly throughout the performance period and will adjust share-based compensation expense if it estimates that the achievement of the performance criteria is not probable. In addition, liability awards with a performance-based vesting condition are remeasured at fair value at each reporting period and the compensation expense is adjusted accordingly. For equity awards with a market-based vesting condition, compensation expense is recognized regardless of whether the market condition is satisfied, provided that the requisite service period has been completed. Conversely, liability awards with market-based vesting requirements are remeasured at fair value at each reporting period using a Monte Carlo simulation model and the compensation expense is adjusted accordingly.
Insurance Liabilities | (p) Insurance Liabilities The Company typically utilizes third-party insurance coverage subject to varying deductible levels with aggregate caps on losses retained. The Company assumes the risk for the amount of the deductible portion of the losses and liabilities primarily associated with workers’ compensation and general liability coverage. In addition, on certain projects, the Company assumes the risk for the amount of the deductible portion of losses that arise from any subcontractor defaults. Losses are accrued based upon the Company’s estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. The estimate of insurance liability within the deductible limits includes an estimate of incurred but not reported claims based on data compiled from historical experience.
Other Comprehensive Income (Loss) | (q) Other Comprehensive Income (Loss) ASC 220, Comprehensive Income, establishes standards for reporting comprehensive income and its components in the consolidated financial statements. The Company reports the change in pension benefit plan assets/liabilities, cumulative foreign currency translation, and the unrealized gain (loss) of investments as components of AOCI.
Recent Accounting Pronouncements | (r) Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (“Topic 280”): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which requires disclosure of incremental segment information on an interim and annual b asis. The Company adopted this ASU for the year ended December 31, 2024 and retrospectively applied its requirements to all prior periods presented in the consolidated financial statements. The adoption of ASU 2023-07 resulted in additional segment disclosures, but no impact on the Company’s financial position, results of operations or cash flows. Refer to Note 14, Business Segments, for additional details. In December 2023, the FASB issued ASU 2023-09, Income Taxes (“Topic 740”): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires public entities to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. ASU 2023-09 also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. This guidance is effective for fiscal years beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (“Subtopic 220-40”): Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. This guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.
