Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Fluor Corporation (“we”, “us”, “our” or “the company”) is a holding company that owns many subsidiaries, as well as interests in joint ventures. Acting through these entities, we are one of the largest professional services firms providing EPC, fabrication and modularization, and project management services, on a global basis. We provide these services to our clients in a diverse set of industries worldwide including production and fuels, chemicals, LNG, nuclear project services, infrastructure, advanced technologies, life sciences and mining and metals. We are also a service provider to the U.S. federal government and governments abroad. During the first quarter of 2021, we changed the composition of our segments to implement our new strategy and to pursue opportunities in our designated markets. We now report our operating results in four segments as follows: Energy Solutions, Urban Solutions, Mission Solutions and Other. Segment operating information and assets for 2020 and 2019 have been recast to conform to these changes. Energy Solutions focuses on opportunities in the production and fuels, chemicals, LNG and nuclear project services market. The segment provides solutions to the energy transition market, including asset decarbonization, carbon capture, renewable fuels, waste-to-energy, green chemicals, hydrogen, nuclear power and other low-carbon energy sources. The segment also continues to serve the traditional oil, gas and petrochemical industries with full project life-cycle services, including expansion and modernization projects as well as sustaining capital work. Urban Solutions provides EPC and project management services to the infrastructure, advanced technologies, life sciences and mining and metals industries, as well as professional staffing services. Mission Solutions focuses on federal agencies across the U.S. government and select international opportunities. These include, among others, the DOE, the Department of Defense, the Federal Emergency Management Agency and intelligence agencies. The segment also provides services to commercial nuclear clients. Other includes only the operations of NuScale, in which we are the majority investor. NuScale is developing an SMR technology. In the first quarter of 2021, we committed to a plan to sell our Stork business, which had previously represented the majority of operations from our former diversified services segment. The sale of the North American portion of the AMECO equipment business was completed during May 2021. Therefore, both Stork and AMECO are reported as Disc Ops along with other immaterial operations. We expect to complete the sale of Stork and the remaining AMECO operations early in 2022. The assets and liabilities of the Stork and AMECO businesses are classified as held for sale for all periods presented. In December 2021, we announced that NuScale, in which we are the majority investor, signed a merger agreement with Spring Valley Acquisition Corp., a special purpose acquisition company ("Spring Valley"). Spring Valley is acquiring an approximately 20% interest in NuScale. The proposed transaction is anticipated to close in the first half of 2022, subject to customary closing conditions. Upon completion of the merger, we estimate that we will own approximately 60-70% of the combined company and expect that we will continue to consolidate it.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Principles of Consolidation The financial statements include the accounts of Fluor Corporation and its subsidiaries. All significant intercompany transactions of consolidated subsidiaries are eliminated. Certain amounts in 2020 and 2019 have been reclassified to conform to the 2021 presentation, which includes the segregation of Disc Ops and assets and liabilities held for sale. Certain amounts in tables may not total or agree to the financial statements due to immaterial rounding differences. Management has evaluated all material events occurring subsequent to December 31, 2021 through the filing date of the 2021 10-K. We frequently form joint ventures or partnerships with others primarily for the execution of single contracts or projects. If a joint venture or partnership is a VIE and we are the primary beneficiary, the joint venture or partnership is consolidated and our partners' interests are recognized as NCI. As is customary in our industry, for unconsolidated construction partnerships and joint ventures, we generally recognize our proportionate share of revenue, cost and profit and use the one-line equity method for the investment. In other instances, the cost and equity methods of accounting are used, depending on our respective ownership interest and amount of influence on the entity, as well as other factors. At times, we also execute projects through collaborative arrangements for which we recognize our relative share of revenue and cost. 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. Foreign Currency Translation Our reporting currency is the U.S. dollar. For our international subsidiaries, the functional currency is typically the currency of the primary economic environment in which each subsidiary operates. Translation gains and losses are recorded in OCI. Gains and losses from remeasuring foreign currency transactions into the functional currency are included in earnings. Revenue Recognition Engineering and construction contracts. We recognize engineering and construction contract revenue over time as we provide services to satisfy our performance obligations. We generally use the cost-to-cost percentage-of-completion measure of progress as it best depicts how control transfers to our clients. The cost-to-cost approach measures progress towards completion based on the ratio of contract cost incurred to date compared to total estimated contract cost. Engineering and construction contracts are generally accounted for as a single unit of account (a single performance obligation) and are not segmented between types of services on a single project. Cost of revenue includes an allocation of depreciation and amortization. Where applicable, customer-furnished materials, labor and equipment and subcontractor materials, labor and equipment, are included in revenue and cost of revenue when management believes that we are acting as a principal rather than as an agent (i.e., we integrate the materials, labor and equipment into the deliverables promised to the customer). Customer-furnished materials are only included in revenue and cost when the contract includes construction activity and we have visibility into the amount the customer is paying for the materials or there is a reasonable basis for estimating the amount. We recognize revenue, but not profit, on certain uninstalled materials that are not specifically produced, fabricated, or constructed for a project. Revenue on these uninstalled materials is recognized when the cost is incurred and control is transferred. Changes to total estimated contract cost or losses, if any, are recognized in the period in which they are determined as assessed at the contract level. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. Project mobilization costs are generally charged to project costs as incurred when they are an integrated part of the performance obligation being transferred to the client. Customer payments on engineering and construction contracts are typically due within 30 to 45 days of billing, depending on the contract. Service contracts. For the majority of our operations and maintenance contracts, revenue is recognized when services are performed and contractually billable. For all other service contracts, we recognize revenue over time using the cost-to-cost percentage-of-completion method. Service contracts that include multiple performance obligations are segmented between types of services. For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation using an estimate of the stand-alone selling price of each distinct service in the contract. Revenue recognized on service contracts that has not been billed to clients is recorded as contract assets. Amounts billed to clients in excess of revenue recognized on service contracts to date are recorded as contract liabilities. Customer payments on service contracts are typically due within 30 to 90 days of billing, depending on the contract. Variable consideration. The nature of our contracts gives rise to several types of variable consideration, including claims, unpriced change orders, award and incentive fees, liquidated damages and penalties. We consider variable consideration in the development of our project forecasts so that our forecasted revenue reflects the amount of consideration we expect to be probable of recovering without a significant reversal. We estimate the amount of revenue to be recognized on variable consideration using the expected value method (i.e., the sum of probability-weighted amounts) or the most likely amount method, whichever offers better prediction. Warranties. We generally provide limited duration warranties for work performed under our contracts. Historically, warranty claims have not resulted in material costs incurred, and any estimated costs for warranties are included in the individual project cost estimates for purposes of accounting for long-term contracts. Practical Expedients. If we have a right to consideration from a customer in an amount that corresponds directly with the value of our performance completed to date (a service contract in which we bill a fixed amount for each hour of service provided), we recognize revenue in the amount to which we have a right to invoice for services performed. We do not adjust the contract price for the effects of a significant financing component where, at contract inception, the period between service provision and customer payment will be one year or less. We exclude from the measurement of the transaction price all taxes assessed by governmental authorities that are collected by us from our customers (use taxes, value added taxes, some excise taxes). RUPO. RUPO represents a measure of the value of work to be performed on contracts awarded and in progress. Although RUPO reflects business that is considered to be firm, cancellations, deferrals or scope adjustments may occur. RUPO is adjusted to reflect any known project cancellations, revisions to project scope and cost, foreign currency exchange fluctuations and project deferrals, as appropriate. RUPO differs from backlog discussed elsewhere in the 2021 10-K. Backlog includes the amount of revenue we expect to recognize under ongoing operations and maintenance contracts for the remainder of the current year renewal period plus up to three additional years if renewal is considered to be probable, while RUPO includes only the amount of revenue we expect to recognize under ongoing operations and maintenance contracts with definite terms and substantive termination provisions. Project Estimates Due to the nature of our industry, there is significant complexity in our estimation of total expected revenue and cost, for which we must make significant judgments. Our contracts with our customers may contain award fees, incentive fees, liquidated damages or other provisions that can either increase or decrease the contract price to arrive at estimated revenue. These variable amounts generally are earned upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. We estimate variable consideration at the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent it is probable we will realize that amount. Our estimates of variable consideration and our determination of its inclusion in project revenue for accounting purposes are based on an assessment of our anticipated performance and other information that may be available to us. At a project level, we have specific practices and procedures to review our estimate of total revenue and cost. Each project team reviews the progress and execution of our performance obligations, which impact the project’s accounting outcome. As part of this process, the project team reviews information such as any outstanding key contract matters, progress towards completion and the related program schedule and identified risks and opportunities. The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our project estimates, which can change from period to period due to a variety of factors including: • Complexity in original design; • Extent of changes from original design; • Different site conditions than assumed in our bid; • The productivity, availability and skill level of labor; • Weather conditions when executing a project; • The technical maturity of the technologies involved; • Length of time to complete the project; • Availability and cost of equipment and materials; • Subcontractor and joint venture partner performance; • Expected costs of warranties; and • Our ability to recover for additional contract costs. We recognize changes in contract estimates on a cumulative catch-up basis in the period in which the changes are identified. Such changes in contract estimates can result in the recognition of revenue in a current period for performance obligations which were satisfied or partially satisfied in prior periods. Changes in contract estimates may also result in the reversal of previously recognized revenue if the current estimate adversely differs from the previous estimate. If we estimate that a project will have costs in excess of revenue, we recognize the total loss in the period it is identified. Contract Assets and Liabilities Contract assets represent revenue recognized in excess of amounts billed and include unbilled receivables (typically for cost reimbursable contracts) and contract work in progress (typically for fixed-price contracts). Unbilled receivables, which represent an unconditional right to payment subject only to the passage of time, are recognized as accounts receivable when they are billed. Advances that are payments on account of contract assets are deducted from contract assets. We anticipate that substantially all incurred cost associated with contract assets as of December 31, 2021 will be billed and collected within one year. Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. Segment Reporting Management evaluates segment performance based on segment profit. We incur cost and expenses and hold certain assets at the corporate level which relate to our business as a whole. Certain of these amounts have been charged to our business segments by various methods, largely on the basis of usage. Total assets not allocated to segments and held in "Corporate and other" primarily include cash, marketable securities, income-tax related assets, pension assets, deferred compensation trust assets and corporate property, plant and equipment. Segment profit is an earnings measure that we utilize to evaluate and manage our business performance. Segment profit is calculated as revenue less cost of revenue and earnings attributable to NCI. Variable Interest Entities We assess our partnerships and joint ventures at inception to determine if any meet the qualifications of a VIE. We consider a partnership or joint venture a VIE if it has any of the following characteristics: (a) the total equity investment is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or their rights to receive the expected residual returns of the entity, and substantially all of the entity's activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events, we reassess our initial determination of whether the partnership or joint venture is a VIE. The majority of our partnerships and joint ventures qualify as VIEs because the total equity investment is typically nominal and not sufficient to permit the entity to finance its activities without additional subordinated financial support. We also perform a qualitative assessment of each identified VIE to determine if we are its primary beneficiary. We conclude that we are the primary beneficiary and consolidate the VIE if we have both: (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. We consider the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining if we are the primary beneficiary. We also consider all parties that have direct or implicit variable interests when determining whether we are the primary beneficiary. Management's assessment of whether we are the primary beneficiary of a VIE is continuously performed. Cash and Cash Equivalents Cash and cash equivalents include securities with maturities of three months or less at the date of purchase. Marketable Securities Marketable securities consist of time deposits placed with investment grade banks with original maturities greater than three months, which are typically held-to-maturity because we have the intent and ability to hold them until maturity. Held-to-maturity securities are carried at amortized cost. The cost of securities sold is determined by using the specific identification method. Marketable securities are assessed at least annually for other-than-temporary impairment. Research and Development We have a controlling interest in NuScale, a research and development operation associated with the licensing and commercialization of SMR technology. Since May 2014, NuScale has been receiving reimbursement from the DOE for certain qualified expenditures under cost-sharing award agreements that require NuScale to use the DOE funds to cover engineering costs associated with SMR design development and certification. Costs incurred by NuScale are expensed as incurred, net of qualifying DOE reimbursements, and reported in "Cost of revenue". The U.S. Nuclear Regulatory Commission approved NuScale's design certification application in August 2020. Aside from NuScale, we generally do not engage in significant research and development activities. Property, Plant and Equipment Property, plant and equipment is recorded at cost. Leasehold improvements are amortized over the shorter of their economic lives or the lease terms. Depreciation is calculated using the straight-line method over the following ranges of estimated useful service lives, in years: Estimated Useful Service Lives Buildings 20 – 40 Building and leasehold improvements 6 – 20 Machinery and equipment 2 – 10 Furniture and fixtures 2 – 10 Goodwill and Intangible Assets Goodwill and intangible assets with indefinite lives are not amortized but are subject to at least annual impairment tests during the fourth quarter. For impairment testing, goodwill is allocated to the applicable reporting units based on the current reporting structure. We may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of each reporting unit is less than its carrying amount. If so, we perform a quantitative test, and if the carrying amount of a reporting unit exceeds its fair value, we recognize an impairment loss. Intangible assets with indefinite lives are impaired if their carrying value exceeds their fair value. In-process research and development associated with our investment in NuScale is considered indefinite lived until the related technology is available for commercial use. Interim impairment testing of goodwill and intangible assets is performed if indicators of potential impairment exist. Such indicators may include the results of operations of certain businesses and geographies and the performance of the company stock price. Intangible assets with finite lives are amortized on a straight-line basis over their useful lives. Income Taxes Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in our financial statements or tax filings. We evaluate the realizability of our deferred tax assets and record a valuation allowance to reduce deferred tax assets to amounts that are more likely than not to be realized. The factors used to assess the likelihood of realization are our forecast of future taxable income and available tax planning strategies that could be implemented to realize such assets. Failure to achieve forecasted taxable income could affect the ultimate realization of deferred tax assets and could adversely impact our future effective tax rate. Income tax positions are recognized when they meet a more-likely-than-not recognition threshold. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized upon such determination. We recognize potential interest and penalties related to unrecognized tax positions as a component of income tax expense. Judgment is required in determining the provision for income taxes as we consider our worldwide taxable earnings and the impact of the continuing audit process conducted by various tax authorities. The final outcome of any audits could differ materially from amounts recognized by the company. We account for the GILTI effects in the period that is subject to such tax. Derivatives and Hedging We may attempt to limit foreign currency exposure in most of our contracts by denominating contract revenue in the currencies in which cost is incurred. Certain financial exposure, which includes currency and commodity price risk associated with engineering and construction contracts, currency risk associated with monetary assets and liabilities denominated in nonfunctional currencies and risk associated with interest rate volatility, may subject us to earnings volatility. We may implement a hedging strategy utilizing derivatives instruments to mitigate such risk. All derivatives are recorded at fair value. The change in the fair value of the derivative is offset against the change in the fair value of the underlying asset or liability through earnings. To a lesser extent, we also utilize cash flow hedges. We formally document our hedge relationships at inception and subsequently assess hedge effectiveness qualitatively, unless the hedge relationship is no longer highly effective. For cash flow hedges, the change in fair value is recorded as a component of AOCI and is reclassified into earnings when the hedged item settles. In certain limited circumstances, foreign currency payment provisions could be deemed embedded derivatives. If an embedded foreign currency derivative is identified, the derivative is bifurcated from the host contract and the change in fair value is recognized through earnings. We maintain master netting arrangements with certain counterparties to facilitate the settlement of derivative instruments; however, we report the fair value of derivatives on a gross basis. Concentrations of Credit Risk Accounts receivable and all contract work in progress are from clients in various industries and locations throughout the world. Most contracts require payments as the projects progress or, in certain cases, advance payments. We generally do not require collateral, but in most cases can place liens against the project assets or terminate the contract, if a material default occurs. We evaluate the counterparty credit risk as part of our project risk review process and in determining the appropriate level of reserves. We maintain reserves for potential credit losses and generally such losses have been minimal and within management's estimates. We have cash and marketable securities on deposit with major banks throughout the world. Such deposits are placed with high quality institutions and the amounts invested in any single institution are limited to the extent possible in order to minimize concentration of counterparty credit risk. Our counterparties for derivatives are large financial institutions selected based on profitability, strength of balance sheet, credit ratings and capacity for timely payment of financial commitments. There are no significant concentrations of credit risk with any individual counterparty related to our derivative contracts. We monitor the credit quality of our counterparties and establish reserves for any significant credit risk losses. Stock-Based Plans Our stock plans provide for grants of nonqualified or incentive stock options, RSUs, restricted stock and performance-based award units, including VDI units. All grants of stock options and RSUs as well as performance-based units awarded to Section 16 officers in 2021, 2020 and 2019 can only be settled in company stock and are accounted for as equity awards. All expense under stock-based awards is recognized based on the fair values of the awards. Stock option awards have grant exercise prices equal to the grant date market price of the company's stock. The fair value of grants of RSUs and restricted stock is determined using the closing price of our common stock on the date of grant but may be discounted for any significant post-vest holding periods. The grant date fair value of performance-based award units is determined by adjusting the closing price of the company's common stock on the date of grant for any post-vest holding period discounts and for the effect of market conditions, when applicable. Stock-based compensation expense is generally recognized over the required service period, or over a shorter period when employee retirement eligibility is a factor. We also grant SGI awards and performance-based awards to non-Section 16 executives which are settled in cash. These awards are classified as liabilities and remeasured at fair value through expense at the end of each reporting period until the awards are settled. Leases We recognize right-of-use assets and lease liabilities for leases with terms greater than 12 months or leases that contain a purchase option that is reasonably certain to be exercised. Leases are classified as either finance or operating leases. This classification dictates whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. Our right-of use assets and lease liabilities primarily relate to office facilities, equipment used in connection with long-term construction contracts and other personal property. Certain of our facility and equipment leases include one or more options to renew, with renewal terms that can extend the lease term up to 10 years. The exercise of lease renewal options is at our discretion. Renewal periods are included in the expected lease term if they are reasonably certain of being exercised by us. Certain leases also include options to purchase the leased property. None of our lease agreements contain material residual value guarantees or material restrictions or covenants. Long-term leases (leases with terms greater than 12 months) are recorded as liabilities at the present value of the minimum lease payments not yet paid. We use our incremental borrowing rate to determine the present value of the lease when the rate implicit in the lease is not readily determinable. Certain lease contracts contain nonlease components such as maintenance, utilities, fuel and operator services. We recognize both the lease component and nonlease components as a single lease component for all of its right-of-use assets. From time to time, certain service or purchase contracts may contain an embedded lease.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Implemented During 2021 In the first quarter of 2021, we adopted ASU 2020-06, “Accounting for Convertible Instruments and Contracts in an Entity's Own Equity,” which simplifies accounting for convertible instruments and the application of the derivatives scope exception for contracts in our own equity. ASU 2020-06 eliminates two of the three models in the prior guidance that required separating embedded conversion features from convertible instruments and also eliminates some of the requirements for equity classification. ASU 2020-06 also addresses how convertible instruments are accounted for in the diluted EPS calculation. The adoption did not have any impact on our financial statements.

Restructuring and Related Activities [Abstract]
Impairment, Restructuring and Other Exit Costs	Impairment, Restructuring and Other Exit Costs Impairment Impairment expense, included in Cont Ops, for 2021, 2020 and 2019 is summarized as follows: Year Ended December 31, (in thousands) 2021 2020 2019 Impairment expense: Energy Solutions' equity method investments $ 27,934 $ 86,096 $ 256,769 Information technology assets 15,858 16,269 — Total impairment expense $ 43,792 $ 102,365 $ 256,769 Our business has been adversely affected by the impacts of COVID and the steep decline in oil prices that occurred in early 2020. These events created significant uncertainty and economic volatility and disruption, which have impacted and may continue to impact our business. We experienced reductions in demand for certain services and the delay or abandonment of ongoing or anticipated projects due to our clients’, suppliers’ and other third parties’ diminished financial condition. Although oil prices have rebounded in 2021 and 2022, we have not yet seen our energy clients respond with elevated capital expenditures for our services. During 2021, 2020 and 2019, we evaluated our significant investments and determined that certain of our investments were impaired. The fair value of these investments were determined using unobservable Level 3 inputs based on the forecast of anticipated volumes and overhead absorption in a cyclical business. Restructuring and Other Exit Costs During 2019, we initiated a restructuring plan designed to optimize costs and improve operational efficiency. These efforts primarily related to the rationalization of resources, investments, real estate and overhead across various geographies. The recognition of costs for the planned restructuring activities was substantially completed by the end of 2020. We did not recognize any material restructuring costs during 2021. Information about our completed restructuring follows: (in thousands) Costs Incurred in 2020 Costs Incurred in Restructuring and other exit costs: Severance $ 5,256 $ 30,530 Asset impairments — 29,485 Other exit costs 736 1,658 Total restructuring and other exit costs $ 5,992 $ 61,673 Asset impairment charges in 2019 included the write down of held-for-sale and held-for-use assets to fair value.

The Company has filed the refund claim with the IRS and received a refund of $49 million in the third quarter of 2020 and expect a refund of $72 million in 2022. A reconciliation of U.S. statutory federal income tax expense (benefit) to income tax expense (benefit) from Cont Ops follows: Year Ended December 31, (in thousands) 2021 2020 2019 U.S. statutory federal tax expense (benefit) $ (26,818) $ 734 $ (176,288) Increase (decrease) in taxes resulting from: State and local income taxes 12,777 (10,817) (5,128) U.S. tax on GILTI — 3,835 21,433 NCI (6,718) (9,143) 13,209 Foreign tax differential, net (23,315) (10,386) 3,989 Valuation allowance, net 99,663 146,930 659,203 Other changes to uncertain tax positions 895 7,484 4,098 Stranded tax effects from AOCI (51,782) — (35,619) CARES Act benefit 2,188 (124,753) — Other, net 9,599 11,972 (2,932) Total income tax expense $ 16,489 $ 15,856 $ 481,965 Deferred taxes reflect the tax effects of differences between the amounts recorded as assets and liabilities for financial reporting purposes and the amounts recorded for income tax purposes. The tax effects of significant temporary differences giving rise to deferred tax assets and liabilities are as follows: December 31, (in thousands) 2021 2020 Deferred tax assets: Accrued liabilities not currently deductible: Employee compensation and benefits $ 138,034 $ 104,305 Project and non-project reserves 67,861 71,999 Net operating loss carryforward 346,561 326,402 Tax basis of investment in excess of book basis 144,019 118,915 U.S. foreign tax credit carryforward 455,912 414,348 AOCI 26,982 62,681 Other 26,794 103,955 Total deferred tax assets 1,206,163 1,202,605 Valuation allowance (1,114,574) (1,080,752) Deferred tax assets, net $ 91,589 $ 121,853 Deferred tax liabilities: Book basis of property and equipment in excess of tax basis (31,197) (43,475) Dividend withholding on unremitted non-U.S. earnings (55,080) (57,859) Other (21,539) (23,349) Total deferred tax liabilities (107,816) (124,683) Deferred tax assets, net of deferred tax liabilities $ (16,227) $ (2,830) As of December 31, 2021, we are indefinitely reinvested only with respect to unremitted earnings required to meet our working capital and long-term investment needs in the foreign jurisdictions within which we operate. Beyond those limits, we expect current earnings to be available for distribution. Deferred tax liabilities of approximately $31 million have not been recorded with respect to unremitted earnings that are considered indefinitely reinvested, again primarily associated with foreign withholding and income taxes that would be due upon remittance. We have no intention of initiating any actions that would lead to taxation of the earnings deemed indefinitely reinvested. As of December 31, 2021, tax credit carryforwards, principally federal, and tax loss carryforwards, principally federal, state, and foreign, were as follows: (in thousands) Federal FTC Federal NOLs State NOLs Foreign NOLs Expiration periods: 2022 - 2026 $ 94,317 $ — $ 10,932 $ 40,177 2027-2031 361,595 — 34,034 56,255 2032-2041 — — 351,159 5,783 Indefinite — 163,099 131,680 1,177,047 During 2021 and 2020, we were in a three-year cumulative loss on a consolidated, jurisdictional basis in Australia, the Netherlands, the U.K. and the U.S. Such cumulative loss constitutes significant negative evidence (with regards to future taxable income) for assessing likelihood of realization. We also considered positive evidence but concluded it did not outweigh this significant negative evidence of a three-year cumulative loss. Accordingly, we recognized non-cash charges to tax expense of $10 million and $142 million to record a valuation allowance against net U.S. deferred tax assets and $42 million and $28 million against certain net foreign deferred tax assets during 2021 and 2020, respectively. We also reduced a valuation allowance for $18 million in AOCI against net deferred tax assets primarily related to the Netherlands' pension settlement that occurred in the fourth quarter of 2021. In the normal course of business, we are subject to examination by taxing authorities worldwide, including such major jurisdictions as Australia, Canada, Chile, the Netherlands, the U.K. and the U.S. Although we believe our reserves for our tax positions are reasonable, the outcome of tax audits could be materially different, both favorably and unfavorably. With a few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 2012. A summary of unrecognized tax benefits follows: (in thousands) 2021 2020 Balance at beginning of year $ 48,413 $ 42,394 Change in tax positions of prior years — 8,166 Change in tax positions of current year — — Reduction in tax positions for statute expirations (514) (1,510) Reduction in tax positions for audit settlements — (637) Balance at end of year $ 47,899 $ 48,413 If recognized, the total amount of unrecognized tax benefits as of December 31, 2021 and 2020, would favorably impact the effective tax rates by $30 million in both years. We had $13 million and $11 million of accrued interest and penalties as of December 31, 2021 and 2020, respectively. We do not anticipate any significant changes to the unrecognized tax benefits within the next twelve months. U.S. and foreign earnings (loss) from Cont Ops before taxes are as follows: Year Ended December 31, (in thousands) 2021 2020 2019 United States $ (176,271) $ (276,041) $ (873,189) Foreign 48,566 279,535 33,724 Total $ (127,705) $ 3,494 $ (839,465)

Equity Method Investments and Joint Ventures [Abstract]
Partnerships and Joint Ventures	Partnerships and Joint Ventures In the normal course of business, we form partnerships or joint ventures primarily for the execution of single contracts or projects. The majority of these partnerships or joint ventures are characterized by a 50% or less, noncontrolling ownership or participation interest, with decision making and distribution of expected gains and losses typically being proportionate to the ownership or participation interest. Many of the partnership and joint venture agreements provide for capital calls to fund operations, as necessary. Investments in a loss position of $240 million were included in other accrued liabilities as of December 31, 2021 and consisted primarily of provision for anticipated losses on a legacy infrastructure project. Accounts receivable related to work performed for unconsolidated partnerships and joint ventures included in "Accounts and notes receivable, net" were $204 million and $207 million as of December 31, 2021 and 2020, respectively. The following is a summary of aggregate, unaudited balance sheet data for unconsolidated entities where our investment is presented as a one-line equity method investment: December 31, (in millions) 2021 2020 Current assets $ 10,154 $ 8,129 Noncurrent assets 3,755 4,744 Current liabilities 7,860 6,301 Noncurrent liabilities 3,527 4,353 The following is a summary of aggregate, unaudited income statement data for unconsolidated entities where the equity method of accounting is used to recognize our share of net earnings or loss of investees: (in millions) 2021 2020 2019 Revenue $ 1,585 $ 1,196 $ 1,211 Cost of revenue 1,000 1,094 1,112 Net earnings 52 54 43 During 2021, 2020 and 2019, we evaluated our significant investments and determined that certain of our investments were impaired. As a result, we recognized impairment expense of $28 million, $86 million and $257 million during 2021, 2020 and 2019, respectively. One of our more significant joint ventures is COOEC Fluor, in which we have a 49% ownership interest. COOEC Fluor owns, operates and manages the Zhuhai Fabrication Yard in China’s Guangdong province. We made a capital contribution of $26 million to the joint venture during the first quarter of 2021, which satisfied our contractual funding requirements. During 2021, we sold our 10% ownership interest in an infrastructure joint venture and recognized a gain of $20 million, which was included in Urban Solutions' segment profit. During 2020, we sold our interests in three infrastructure joint ventures and recognized a gain of $8 million. We also sold our 50% ownership interest in Sacyr Fluor and recognized a loss of $11 million, which was included in Energy Solutions' segment profit. Variable Interest Entities The aggregate carrying value of the unconsolidated VIEs (classified under both "Investments" and "Other accrued liabilities") was a net asset of $30 million and $174 million as of December 31, 2021 and 2020, respectively. Some of our VIEs have debt; however, such debt is typically non-recourse in nature to Fluor. Our maximum exposure to loss as a result of our investments in unconsolidated VIEs is typically limited to the aggregate of the carrying value of the investment and future funding necessary to satisfy the contractual obligations of the VIE. Future funding commitments as of December 31, 2021 for the unconsolidated VIEs were $57 million. In some cases, we are required to consolidate certain VIEs. Assets and liabilities associated with the operations of our consolidated VIEs are presented on the balance sheet. The assets of a VIE are restricted for use only for the particular VIE and are not available for our general operations. We have agreements with certain VIEs to provide financial or performance assurances to clients, as discussed elsewhere.

Guarantees

Guarantees [Abstract]
Guarantees	Guarantees In the ordinary course of business, we enter into various agreements providing performance assurances and guarantees to our clients on behalf of certain unconsolidated and consolidated partnerships, joint ventures and other jointly executed contracts. These agreements are entered into primarily to support project execution commitments. Performance guarantees have various expiration dates ranging from mechanical completion to a period extending beyond contract completion. The maximum potential amount of future payments that we could be required to make under outstanding performance guarantees, which represents the remaining cost of work to be performed, was estimated to be $15 billion as of December 31, 2021. For cost reimbursable contracts, amounts that may become payable pursuant to guarantee provisions are normally recoverable from the client for work performed. For lump-sum contracts, the performance guarantee amount is the cost to complete the contracted work, less amounts remaining to be billed to the client under the contract. Remaining billable amounts could be greater or less than the cost to complete. In those cases where costs exceed the remaining amounts payable under the contract, we may have recourse to third parties, such as owners, partners, subcontractors or vendors for claims. There were no liabilities related to performance guarantees as of December 31, 2021 and 2020. In certain limited circumstances, financial guarantees are entered into with financial institutions and other credit grantors and generally obligate us to make payment in the event of a default by the borrower. These arrangements generally require the borrower to pledge collateral to support the fulfillment of the borrower's obligation.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Contingencies and Commitments We and certain of our subsidiaries are subject to litigation, claims and other commitments and contingencies arising in the ordinary course of business. Although the asserted value of these matters may be significant, we currently do not expect that the ultimate resolution of any open matters will have a material adverse effect on our financial position or results of operations. Since May 2018, purported shareholders have filed various complaints against Fluor and certain of its current and former executives in the U.S. District Court for the Northern District of Texas. The plaintiffs purport to represent a class of shareholders who purchased or otherwise acquired Fluor common stock from August 14, 2013 through February 14, 2020, and seek to recover damages arising from alleged violations of federal securities laws. These claims are based on statements concerning Fluor’s internal and disclosure controls, risk management, revenue recognition, and Fluor’s gas-fired power contracts, which plaintiffs assert were materially misleading. As of May 26, 2020, these complaints have been consolidated into one matter. We filed a motion to dismiss the matter on July 1, 2020. The motion was granted in part on May 5, 2021, and as a result the Court dismissed with prejudice all allegations except those related to a single statement made in 2015 about one gas-fired power contract. While no assurance can be given as to the ultimate outcome of this matter, during 2021 we recorded a liability for the estimated resolution of the matter and we also recognized the effects of expected insurance coverage. Since September 2018, eleven separate purported shareholders' derivative actions were filed against current and former members of the Board of Directors, as well as certain of Fluor’s current and former executives. Fluor is named as a nominal defendant in the actions. These derivative actions purport to assert claims on behalf of Fluor and make substantially the same factual allegations as the securities class action matter discussed above and seek various forms of monetary and injunctive relief. These actions are pending in Texas state court (District Court for Dallas County), the U.S. District Court for the District of Delaware, the U.S. District Court for the Northern District of Texas, and the Court of Chancery of the State of Delaware. Certain of these actions were consolidated and stayed, at least while our motion to dismiss was pending in the securities class action matter. We anticipate seeking a further stay until final resolution of the securities class action. While no assurance can be given as to the ultimate outcome of this matter, we do not believe it is probable that a loss will be incurred. Accordingly, we have not recorded any liability as a result of these actions. Fluor Australia Ltd., our wholly-owned subsidiary (“Fluor Australia”), completed a cost reimbursable engineering, procurement and construction management services project for Santos Ltd. (“Santos”) involving a large network of natural gas gathering and processing facilities in Queensland, Australia. On December 13, 2016, Santos filed an action in Queensland Supreme Court against Fluor Australia, asserting various causes of action and seeking damages and/or a refund of contract proceeds paid of approximately AUD $1.47 billion. Santos has joined Fluor to the matter on the basis of a parent company guarantee issued for the project. We believe that the claims asserted by Santos are without merit and we are vigorously defending these claims. While no assurance can be given as to the ultimate outcome of this matter, we do not believe it is probable that a loss will be incurred. Accordingly, we have not recorded any liability as a result of this action. Fluor Limited, our wholly-owned subsidiary (“Fluor Limited”), and Fluor Arabia Limited, a partially-owned subsidiary (“Fluor Arabia”), completed cost reimbursable engineering, procurement and construction management services for Sadara Chemical Company (“Sadara”) involving a large petrochemical facility in Jubail, Kingdom of Saudi Arabia. On August 23, 2019, Fluor Limited and Fluor Arabia Limited commenced arbitration proceedings against Sadara after it refused to pay invoices totaling approximately $100 million due under the contracts. As part of the arbitration proceedings, Sadara has asserted various counterclaims for damages and/or a refund of contract proceeds paid totaling approximately $574 million against Fluor Limited and Fluor Arabia Limited. We believe that the counterclaims asserted by Sadara are without merit and are vigorously defending these claims. While no assurance can be given as to the ultimate outcome of the counterclaims, we do not believe it is probable that a loss will be incurred in excess of amounts reserved for this matter. Accordingly, we have not recorded any further liability as a result of the counterclaims. Various wholly-owned subsidiaries of Fluor, in conjunction with a partner, TECHINT, (“Fluor/TECHINT”) performed engineering, procurement and construction management services on a cost reimbursable basis for Barrick Gold Corporation involving a gold mine and ore processing facility on a site straddling the border between Argentina and Chile. In 2013, Barrick terminated the Fluor/TECHINT agreements for convenience and not due to the performance of Fluor/TECHINT. On August 12, 2016, Barrick filed a notice of arbitration against Fluor/TECHINT, demanding damages and/or a refund of contract proceeds paid of not less than $250 million under various claims relating to Fluor/TECHINT’s alleged performance. Proceedings were suspended while the parties explored a possible settlement. In August 2019, Barrick drew down $36 million of letters of credit from Fluor/TECHINT ($24 million from Fluor and $12 million from TECHINT). Thereafter, Barrick proceeded to reactivate the arbitration. Barrick and Fluor/TECHINT have exchanged detailed statements of claim and counterclaim pursuant to which Barrick’s claim against Fluor/TECHINT now totals approximately $364 million. We believe that the claims asserted by Barrick are without merit and are vigorously defending these claims. While no assurance can be given as to the ultimate outcome of this matter, we do not believe it is probable that a loss will be incurred. Accordingly, we have not recorded any liability as a result of these claims. Other Matters We have made claims arising from the performance under our contracts. Factors considered in determining whether revenue associated with claims should be recognized include: (a) the legal basis for the claim, (b) additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in our performance, (c) claim-related costs are identifiable and considered reasonable in view of the work performed, and (d) evidence supporting the claim is objective and verifiable. Similarly, we recognize disputed back charges to suppliers or subcontractors as a reduction of cost when the same requirements have been satisfied. We periodically evaluate our positions and the amounts recognized with respect to all our claims and back charges. As of December 31, 2021 and 2020, we had recorded $215 million and $216 million, respectively, of claim revenue for costs incurred to date. Additional costs, which will increase the claim revenue balance over time, are expected to be incurred in future periods. We had no material disputed back charges to suppliers or subcontractors as of December 31, 2021 and 2020. From time to time, we enter into contracts with the U.S. government and its agencies. Government contracts are subject to audits and reviews by government representatives with respect to our compliance with various restrictions and regulations applicable to government contractors, including but not limited to the allowability of costs incurred under reimbursable contracts. In connection with performing government contracts, we maintain reserves for estimated exposures associated with these matters. Our operations are subject to and affected by federal, state and local laws and regulations regarding the protection of the environment. We maintain reserves for potential future environmental cost where such obligations are either known or considered probable, and can be reasonably estimated. We believe that our reserves with respect to future environmental cost are adequate and such future cost will not have a material effect on our financial position or results of operations. In February 2020, we announced that the SEC is conducting an investigation and has requested documents and information related to projects for which we recorded charges in the second quarter of 2019. In April 2020 and January 2022, Fluor received subpoenas from the U.S. Department of Justice (“DOJ”) seeking documents and information related to the second quarter 2019 charges; certain of the projects associated with those charges; and certain project accounting, financial reporting and governance matters. Such inquiries are ongoing, and we have continued to respond to the SEC and DOJ and cooperate in these investigations.

This credit facility contains customary financial covenants, including a debt-to-capitalization ratio that cannot exceed 0.65 to 1.00, a limitation on the aggregate amount of debt of the greater of $750 million or €750 million for our subsidiaries, and a minimum liquidity threshold of $1.25 billion, all as defined in the credit facility. The credit facility also contains provisions that will require us to provide collateral if we are downgraded to BB by S&P and Ba2 by Moody's, such collateral consisting broadly of liens on our U.S. assets. Borrowings under the facility, which may be denominated in USD, EUR, GBP or CAD, bear interest at a base rate, plus an applicable borrowing margin. As of December 31, 2021, we could have borrowed an additional $779 million under our credit facility. In February 2022, we amended our credit facility to extend the maturity to February 2025, increase the size of the facility to $1.8 billion and decrease the debt-to-capitalization ratio to 0.60 to 1.00. Uncommitted Lines of Credit As of December 31, 2021, letters of credit totaling $896 million were outstanding under uncommitted lines of credit, although no amounts were drawn. Senior Notes In September 2021, we completed a tender offer in which we repurchased $375 million of 2023 Notes and $108 million of 2024 Notes, excluding accrued interest. Additionally, we redeemed $26 million of outstanding 2023 and 2024 Notes in open market transactions during the 2021 period. We used the proceeds from the issuance of CPS to redeem the 2023 and 2024 Notes. We recognized $20 million in losses related to these redemptions which is included in interest expense. In August 2018, we issued $600 million of 4.250% Senior Notes due in September 2028 ("2028 Notes") and received proceeds of $595 million. Interest on the 2028 Notes is payable semi-annually in March and September. Prior to June 2028, we may redeem the 2028 Notes at a redemption price equal to 100% of the principal amount, plus a “make whole” premium described in the indenture. After June 2028, the 2028 Notes can be redeemed at par plus accrued interest. In March 2016, we issued €500 million of 1.750% Senior Notes due in March 2023 ("2023 Notes") and received proceeds of €497 million. Interest on the 2023 Notes is payable annually in March. Prior to December 2022, we may redeem the 2023 Notes at a redemption price equal to 100% of the principal amount, plus a "make whole" premium described in the indenture. After December 2022, the 2023 Notes can be redeemed at par plus accrued interest. Additionally, we may redeem the 2023 Notes at par plus accrued interest if certain changes in U.S. tax laws occur. In November 2014, we issued $500 million of 3.5% Senior Notes due in December 2024 ("2024 Notes") and received proceeds of $491 million. Interest on the 2024 Notes is payable semi-annually in June and December. Prior to September 2024, we may redeem the 2024 Notes at a redemption price equal to 100% of the principal amount, plus a "make whole" premium described in the indenture. After September 2024, the 2024 Notes can be redeemed at par plus accrued interest. For all of the Senior Notes, a change of control (as defined by the terms of the respective indentures) could require the company to repay them at 101% of the principal amount, plus accrued interest. We may incur additional indebtedness if we are in compliance with certain restrictive covenants, including restrictions on liens and restrictions on sale and leaseback transactions.

Preferred Stock

Preferred Stock	12 Months Ended
	Dec. 31, 2021
Equity [Abstract]
Preferred Stock	Preferred Stock In May 2021, we issued 600,000 shares of Series A 6.5% cumulative perpetual CPS in a private placement transaction involving a limited number of qualified institutional buyers. The CPS, with respect to dividend rights or rights upon liquidation, winding-up or dissolution of Fluor, ranks senior to all classes of common stock and to any other class of capital stock or series of preferred stock that may be established (except in certain circumstances). The CPS is, however, junior to our existing and future debt. The CPS does not have a maturity date. Cumulative cash dividends on the preferred stock are payable at an annual rate of 6.5% quarterly in arrears on February 15, May 15, August 15 and November 15, upon declaration of the dividend by our Board of Directors. Dividends accumulate from the most recent date on which dividends have been paid. CPS dividends of $9 million and $10 million were paid in August 2021 and October 2021, respectively. In January 2022, our Board of Directors approved the payment of a preferred stock dividend of $10 million. Each share of preferred stock has a liquidation preference of $1,000 per share, plus accumulated but unpaid dividends, and is convertible, at the holder's option at any time into 44.9585 shares of our common stock per share of preferred stock. The conversion rate is subject to certain customary adjustments, but no payment or adjustment for accumulated but unpaid dividends will be made upon conversion, subject to certain limited exceptions. The preferred stock may not be redeemed by us; however, we may, at any time on or after May 20, 2022, elect to cause all outstanding shares of preferred stock to be automatically converted into shares of our common stock at the conversion rate, subject to certain conditions (and, if such automatic conversion occurs prior to May 20, 2024, the payment of a cash make-whole premium). If a make-whole fundamental change, as defined in the certificate of designations for the preferred stock, occurs, we will in certain circumstances be required to increase the conversion rate for a holder who elects to convert shares of preferred stock in connection with such make-whole fundamental change. The shares of preferred stock have no voting rights except if and when dividends on the preferred stock are in arrears and have been unpaid with respect to six or more quarterly dividend payment dates (whether or not consecutive). In such events, the holders of the preferred stock would be entitled to elect two additional directors to the board of directors. Such voting rights are exercisable until all dividends in arrears have been paid in full, at which time the voting rights and the term of the two additional directors terminate.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels: • Level 1 — quoted prices in active markets for identical assets and liabilities • Level 2 — inputs other than quoted prices in active markets for identical assets and liabilities that are observable, either directly or indirectly • Level 3 — unobservable inputs We perform procedures to verify the reasonableness of pricing information received from third parties for significant assets and liabilities classified as Level 2. The following table delineates assets and liabilities that are measured at fair value on a recurring basis: December 31, 2021 December 31, 2020 (in thousands) Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Deferred compensation trusts (1) $ 11,952 $ 11,952 $ — $ — $ 9,626 $ 9,626 $ — $ — Derivative assets (2) Foreign currency 15,308 — 15,308 — 22,667 — 22,667 — Commodity 5,225 — 5,225 — 806 — 806 — Liabilities: Derivative liabilities (2) Foreign currency $ 6,528 $ — $ 6,528 $ — $ 2,571 $ — $ 2,571 $ — Commodity 232 — 232 — 5,059 — 5,059 — (1) Consists of registered money market funds and an equity index fund.

Generally, upon termination of employment, RSUs and restricted stock which have not vested are forfeited. RSUs granted to executives in 2021, 2020 and 2019 generally vest over 3 years. RSUs granted to one executive in 2020 vest over 5 years. RSUs granted to directors in 2021, 2020 and 2019 vested upon grant. RSUs awarded to directors in 2019 (as well as one RSU award to a director in 2020) are subject to a post-vest holding period of 3 years. The fair value of RSUs that vested during 2021, 2020 and 2019 was $14 million, $5 million and $14 million, respectively. The balance of unamortized RSU expense as of December 31, 2021 was $6 million, which is expected to be recognized over a weighted-average period of 2.0 years. The exercise price of options represents the closing price of our common stock on the date of grant. The options granted in 2021, 2020 and 2019 generally vest over 3 years and expire 10 years after the grant date. Options granted to one executive in 2020 vest over 5 years. The aggregate intrinsic value of stock options exercised during 2021 and 2019 was $0.8 million and $0.3 million, respectively. There were no stock option exercises during 2020. The balance of unamortized stock option expense as of December 31, 2021 was $3 million, which is expected to be recognized over a weighted-average period of 1.0 year. The grant date fair value of options and other significant assumptions follow: 2021 January 1 - November 30, 2020 December 31, 2020 January 1 - September 30, 2019 October 1 - December 31, 2019 Weighted average grant date fair value $8.94 $4.59 $9.05 $7.99 $6.93 Expected life of options (in years) 4.5 4.6 7.2 5.6 5.4 Risk-free interest rate 0.7 % 0.4 % 0.5 % 2.6 % 1.7 % Expected volatility 62 % 65 % 61 % 33 % 47 % Expected annual dividend per share $0.00 $0.00 $0.00 $0.84 $0.40 The computation of the expected volatility assumption used in the Black-Scholes calculations is based on a 50/50 blend of historical and implied volatility.

During 2021, 2020 and 2019, performance-based award units totaling 613,868; 1,156,365; and 350,532, respectively, were awarded to Section 16 officers. These awards generally cliff vest after a period of 3 years and contain annual performance conditions for each of the 3 years of the vesting period. Under GAAP, performance-based awards are not deemed granted until the performance targets have been established. The performance targets for each year are generally established in the first quarter. Accordingly, only one-third of the units awarded in any given year are deemed to be granted each year of the 3 year vesting periods. During 2021, the following units were granted based upon the establishment of performance targets: Performance-based Award Units Granted in 2021 Weighted 2021 Performance Award Plan 204,623 $20.49 2020 Performance Award Plan 385,455 $19.98 2019 Performance Award Plan 116,844 $20.18 For awards granted under the 2021, 2020 and 2019 performance award plans, the number of units are adjusted at the end of each performance period based on achievement of certain performance targets and market conditions, as defined in the award agreements. The balance of unamortized compensation expense associated with performance-based award units as of December 31, 2021 was less than $2 million, which is expected to be recognized over a weighted-average period of 1.0 years. Liability Awards We grant SGI awards in the form of stock units, determined by dividing the target amount by the closing price of our common stock at the grant date. Each stock unit represents the right to receive cash equal to the value of one share of our common stock upon vesting. SGI awards granted to executives vest and become payable at a rate of one-third of the total award each year. Compensation expense of $67 million, $25 million and $6 million related to SGI awards was included in G&A in 2021, 2020 and 2019, respectively. Liabilities associated with SGI awards were $73 million and $29 million as of December 31, 2021 and 2020, respectively. During 2021, 2020 and 2019, performance-based awards were awarded to non-Section 16 executives and will be settled in cash. Compensation expense of $7 million, $3 million and $8 million related to these performance-based awards was included in G&A in 2021, 2020 and 2019, respectively. Liabilities associated with these awards were $7 million and $16 million as of December 31, 2021 and 2020, respectively.

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans DC Plans Domestic and international DC plans are available to eligible salaried and craft employees. Company contributions to DC plans are based on an employee's eligible compensation and participation rate. We recognized expense of $128 million, $130 million and $115 million associated with contributions to our DC plans during 2021, 2020 and 2019, respectively. DB Plans Certain DB plans are available to eligible international salaried employees. Contributions to DB plans are at least the minimum amounts required by applicable regulations. Benefit payments under these plans are generally based upon length of service and/or qualifying compensation. Net periodic pension expense for our DB Plans included the following components: Year Ended December 31, (in thousands) 2021 2020 2019 Service cost $ 17,490 $ 18,129 $ 15,750 Interest cost 7,333 9,899 19,617 Expected return on assets (28,577) (26,304) (32,645) Amortization of prior service credit (856) (903) (886) Recognized net actuarial loss 5,875 5,806 10,303 Curtailments 15 — — (Gain) loss on settlements 198,132 (406) 137,898 Net periodic pension expense (1) $ 199,412 $ 6,221 $ 150,037 (1) Net periodic pension expense of $1 million, $2 million and $2 million during 2021, 2020 and 2019, respectively, was reported as Disc Ops. The service cost component of net periodic pension expense is presented in “Cost of revenue” and the other components of net periodic pension expense are presented in “G&A” and "(Gain) loss on pension settlement". Plan Settlements Our largest DB plan, which provided retirement benefits to certain employees in the Netherlands, was terminated in December 2021, at which point the remaining benefit obligations were transferred to a plan not sponsored by Fluor and we were substantially relieved of any further obligation. Our DB plan in the United Kingdom was terminated in December 2019, at which point the remaining benefit obligations were transferred to an insurer and we were relieved of any further obligation. The loss on settlement in both years consisted primarily of unrecognized actuarial losses included in AOCI and did not impact our cash position. Retirement benefits in these countries are now administered through DC plans. DB Plan Assumptions The ranges of assumptions indicated below cover DB plans in the Netherlands, Germany and the Philippines and are based on the economic environment in each host country at the end of each reporting period. The discount rates for the DB plans were determined primarily based on a hypothetical yield curve developed from the yields on high quality corporate and government bonds with durations consistent with the pension obligations in those countries. The expected long-term rate of return on asset assumptions utilizing historical returns, correlations and investment manager forecasts are established for all relevant asset classes including international equities and government, corporate and other debt securities. December 31, 2021 2020 2019 For determining PBO at year-end: Discount rates 1.20-4.75% 0.80-3.50% 1.20-4.75% Rates of increase in compensation levels 2.25-5.00% 2.25-6.00% 2.25-6.00% For determining net periodic cost for the year: Discount rates 0.80-3.50% 1.20-4.75% 1.80-7.25% Rates of increase in compensation levels 2.25-6.00% 2.25-6.00% 2.25-7.00% Expected long-term rates of return on assets 0.80-5.70% 1.20-5.60% 1.80-8.20% We evaluate the funded status of each of our DB plans using the above assumptions and determine the appropriate funding level in light of applicable regulatory requirements, tax deductibility, reporting considerations and other factors. The funding status of the plans is sensitive to changes in long-term interest rates and returns on plan assets, and funding obligations could increase substantially if interest rates fall dramatically or returns on plan assets are below expectations. Assuming no changes in current assumptions, we expect to contribute up to $13 million to our DB plans in 2022, which is expected to be in excess of the minimum funding required. If the discount rates were reduced by 25 basis points, plan liabilities would increase by approximately $5 million. DB Plan Assets The following table sets forth the target and actual allocations of plan assets: December 31, 2021 Target Allocation 2021 2020 Asset category: Debt securities 25% - 35% 28 % 63 % Equity securities 10% - 20% 17 % 28 % Other 50% - 60% 55 % 9 % Total 100 % 100 % Our investment strategy is to maintain asset allocations that appropriately manage risk within the context of seeking adequate returns. Investment allocations are determined by each plan's governing body. Asset allocations may be affected by local regulations. Long-term allocation guidelines are established with a target range allocation for each asset class. Short-term deviations from these allocations may exist from time to time for tactical investment or strategic implementation purposes. Investments in debt securities are used to provide stable investment returns while protecting the funding status of the plans. Investments in equity securities are utilized to generate long-term capital appreciation to mitigate the effects of increases in benefit obligations resulting from inflation, longer life expectancy and salary growth. While most of our plans may invest in the company's securities, there are no such direct investments at the present time. Plan assets included investments in common or collective trusts ("CCTs"), which offer efficient access to diversified investments across various asset categories. The estimated fair value of the investments in the CCTs represents the net asset value of the shares or units of such funds as determined by the issuer. At the present time, there no restrictions on how the plans may redeem their investments. Debt securities are comprised of corporate bonds, government securities and CCTs with underlying investments in corporate bonds, government and asset backed securities and interest rate swaps. Corporate bonds primarily consist of investment-grade rated bonds and notes, of which no significant concentration exists in any one rating category or industry. Government securities include international government bonds, some of which are inflation-indexed. Corporate bonds and government securities are valued based on pricing models, which are determined from a compilation of primarily observable market information, broker quotes in non-active markets or similar assets. Equity securities span various industries and are comprised of common stocks of international companies as well as CCTs with underlying investments in common and preferred stocks. Publicly traded corporate equity securities are valued based on the closing price of an active market or exchange. Inactive securities are valued at the last reported bid price. As of December 31, 2021 and 2020, direct investments in equity securities were concentrated in international securities. Other plan assets include guaranteed investment contracts and CCTs. Guaranteed investment contracts are insurance contracts that guarantee a principal repayment and a stated rate of interest. The estimated fair value of these insurance contracts, which are Level 3 assets, represents the discounted value of guaranteed benefit payments. CCTs hold underlying investments primarily in commodities. The following table delineates the fair value of the plan assets and liabilities of our DB Plans: December 31, 2021 December 31, 2020 (in thousands) Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Equity securities: Common stock $ 4,798 $ 4,798 $ — $ — $ 5,252 $ 5,252 $ — $ — CCTs 758 — 758 — 230,135 — 230,135 — Debt securities: Corporate bonds 45 — 45 — 532 — 532 — Government securities 9,287 — 9,287 — 12,036 — 12,036 — CCTs — — — — 507,691 — 507,691 — Other: Guaranteed investment contracts 17,931 — — 17,931 20,588 — — 20,588 CCTs — — — — 51,679 — 51,679 — Plan assets measured at fair value, net $ 32,819 $ 4,798 $ 10,090 $ 17,931 $ 827,913 $ 5,252 $ 802,073 $ 20,588 Plan assets not measured at fair value, net 55 1,507 Total plan assets, net $ 32,874 $ 829,420 The following table presents information about Level 3 fair value measurements: (in thousands) 2021 2020 Balance at beginning of year $ 20,588 $ 19,650 Actual return on plan assets: Assets still held at reporting date (1,565) 2,092 Assets sold during the period — — Purchases 224 343 Settlements (1,316) (1,497) Balance at end of year $ 17,931 $ 20,588 The following table presents expected future benefit payments related to our DB Plans: Year Ended December 31, (in thousands) 2022 $ 4,383 2023 4,186 2024 4,141 2025 4,116 2026 3,987 2027 — 2031 25,810 The following table sets forth the change in PBO, plan assets and funded status of the plans: December 31, (in thousands) 2021 2020 Change in PBO: Benefit obligation at beginning of year $ 869,835 $ 748,784 Service cost 17,490 18,129 Interest cost 7,333 9,899 Employee contributions 2,643 2,860 Currency translation (32,064) 72,178 Actuarial (gain)/loss (primarily due to plan experience in 2021 and assumption changes in 2020) 52,190 58,258 Benefits paid (15,582) (17,224) Curtailments (415) (6,574) Settlements (798,679) (16,475) PBO at end of year 102,751 869,835 Change in plan assets: Plan assets at beginning of year 829,420 710,663 Actual return on plan assets 30,326 55,819 Company contributions 12,886 24,752 Employee contributions 2,643 2,860 Currency translation (28,140) 69,025 Benefits paid (15,582) (17,224) Settlements (798,679) (16,475) Plan assets at end of year 32,874 829,420 Funded status — (Under)/overfunded $ (69,877) $ (40,415) Amounts recognized in the Consolidated Balance Sheet: Pension assets included in other assets $ — $ — Pension liabilities included in other accrued liabilities — — Pension liabilities included in current liabilities related to assets held for sale (22,248) (25,617) Pension liabilities included in noncurrent liabilities (47,629) (14,798) AOCI (pre-tax) $ 3,042 $ 161,534 Plans with PBO in excess of plan assets: PBO $ 102,751 $ 869,835 Plan assets 32,874 829,420 Plans with ABO in excess of plan assets: ABO $ 40,374 $ 45,757 Plan assets 17,931 20,588 The total ABO for all DB Plans as of December 31, 2021 and 2020 was $55 million and $793 million, respectively. Multiemployer Pension Plans In addition to our DB plans, we participate in multiemployer pension plans for unionized construction and maintenance craft employees. Company contributions are based on the hours worked by employees covered under various collective bargaining agreements and totaled $44 million, $38 million and $32 million during 2021, 2020 and 2019, respectively. Upon withdrawal from a multiemployer plan, we may have an obligation to make additional contributions for our share of any unfunded benefit obligation, but only if we do not meet the requirements of any applicable exemptions. For one of our discontinued operations, we participate in a multiemployer plan in which we are aware of a significant unfunded benefit obligation. However, we believe we qualify for an exemption and do not believe we have a probable payment to the plan.

Other Liabilities, Noncurrent [Abstract]
Other Noncurrent Liabilities	Other Noncurrent LiabilitiesWe have deferred compensation plans and other retirement arrangements for executives which generally provide for payments upon retirement, death or termination of employment. As of December 31, 2021 and 2020, the obligations related to these plans totaled $324 million and $329 million, respectively, within noncurrent liabilities. To fund these obligations, we have established non-qualified trusts, which are included in noncurrent assets. These trusts hold life insurance policies and marketable securities. These trusts were valued at $330 million and $350 million as of December 31, 2021 and 2020, respectively. Periodic changes in the value of these trust investments, most of which are unrealized, are recognized in earnings, and serve to mitigate changes to the obligations which are also reflected in earnings.We maintain appropriate levels of insurance for business risks, including workers compensation and general liability. Insurance coverages contain various retention amounts for which we provide accruals based on the aggregate of the liability for reported claims and an actuarially determined estimated liability for claims incurred but not reported. As of December 31, 2021 and 2020, insurance liabilities of $58 million and $70 million, respectively, were included in noncurrent liabilities.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued OperationsIn the first quarter of 2021, we committed to a plan to sell our Stork business, which had previously represented the majority of operations from our former diversified services segment. We sold the North American operations of the AMECO equipment business in May 2021 for $71 million and recognized a loss on the sale of $27 million. In August 2020, we sold our AMECO equipment business in Jamaica for $18 million and recognized a loss of $1 million. Smaller AMECO operations in South America and Africa remain held for sale. Impairment expense, included in Disc Ops, is summarized as follows: Year Ended Year Ended Year Ended December 31, 2019 (in thousands) Stork AMECO Stork AMECO Stork AMECO Impairment expense: Goodwill (1) $ 12,700 $ — $ 168,568 $ 12,300 $ — $ 2,125 Intangible customer relationships (2) — — 26,671 — 33,657 — Fair value adjustment and expected costs associated with sale (3) 180,500 53,085 — 133,400 — — Total impairment expense $ 193,200 $ 53,085 $ 195,239 $ 145,700 $ 33,657 $ 2,125 (1) As part of our assessment of goodwill in 2020, the fair value of the reporting units was determined using an income based approach that utilized unobservable Level 3 inputs, including significant management assumptions such as expected awards, forecasted revenue and operating margins, weighted average cost of capital, working capital assumptions and general market trends and conditions. (2) The customer relationships' valuation approach utilized unobservable Level 3 inputs including ranges of assumptions of long-term revenue growth from 2% to 5.5% with a weighted average of 2.4%, weighted average cost of capital of 12% and a customer attrition factor of 10%. (3) The fair value of the Stork and AMECO assets were determined using a combination of observable level 2 inputs in 2021, including indicative offers and ongoing negotiations for the related assets, and an income based approach that utilized unobservable Level 3 inputs in 2020, including significant management assumptions such as expected awards, forecasted revenue and operating margins, weighted average cost of capital, working capital assumptions and general market trends and conditions.

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The financial statements include the accounts of Fluor Corporation and its subsidiaries. All significant intercompany transactions of consolidated subsidiaries are eliminated. Certain amounts in 2020 and 2019 have been reclassified to conform to the 2021 presentation, which includes the segregation of Disc Ops and assets and liabilities held for sale. Certain amounts in tables may not total or agree to the financial statements due to immaterial rounding differences. Management has evaluated all material events occurring subsequent to December 31, 2021 through the filing date of the 2021 10-K. We frequently form joint ventures or partnerships with others primarily for the execution of single contracts or projects. If a joint venture or partnership is a VIE and we are the primary beneficiary, the joint venture or partnership is consolidated and our partners' interests are recognized as NCI. As is customary in our industry, for unconsolidated construction partnerships and joint ventures, we generally recognize our proportionate share of revenue, cost and profit and use the one-line equity method for the investment. In other instances, the cost and equity methods of accounting are used, depending on
Use of Estimates	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.
Foreign Currency Translation	Foreign Currency Translation Our reporting currency is the U.S. dollar. For our international subsidiaries, the functional currency is typically the currency of the primary economic environment in which each subsidiary operates. Translation gains and losses are recorded in OCI. Gains and losses from remeasuring foreign currency transactions into the functional currency are included in earnings.
Revenue Recognition	Revenue Recognition Engineering and construction contracts. We recognize engineering and construction contract revenue over time as we provide services to satisfy our performance obligations. We generally use the cost-to-cost percentage-of-completion measure of progress as it best depicts how control transfers to our clients. The cost-to-cost approach measures progress towards completion based on the ratio of contract cost incurred to date compared to total estimated contract cost. Engineering and construction contracts are generally accounted for as a single unit of account (a single performance obligation) and are not segmented between types of services on a single project. Cost of revenue includes an allocation of depreciation and amortization. Where applicable, customer-furnished materials, labor and equipment and subcontractor materials, labor and equipment, are included in revenue and cost of revenue when management believes that we are acting as a principal rather than as an agent (i.e., we integrate the materials, labor and equipment into the deliverables promised to the customer). Customer-furnished materials are only included in revenue and cost when the contract includes construction activity and we have visibility into the amount the customer is paying for the materials or there is a reasonable basis for estimating the amount. We recognize revenue, but not profit, on certain uninstalled materials that are not specifically produced, fabricated, or constructed for a project. Revenue on these uninstalled materials is recognized when the cost is incurred and control is transferred. Changes to total estimated contract cost or losses, if any, are recognized in the period in which they are determined as assessed at the contract level. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. Project mobilization costs are generally charged to project costs as incurred when they are an integrated part of the performance obligation being transferred to the client. Customer payments on engineering and construction contracts are typically due within 30 to 45 days of billing, depending on the contract. Service contracts. For the majority of our operations and maintenance contracts, revenue is recognized when services are performed and contractually billable. For all other service contracts, we recognize revenue over time using the cost-to-cost percentage-of-completion method. Service contracts that include multiple performance obligations are segmented between types of services. For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation using an estimate of the stand-alone selling price of each distinct service in the contract. Revenue recognized on service contracts that has not been billed to clients is recorded as contract assets. Amounts billed to clients in excess of revenue recognized on service contracts to date are recorded as contract liabilities. Customer payments on service contracts are typically due within 30 to 90 days of billing, depending on the contract. Variable consideration. The nature of our contracts gives rise to several types of variable consideration, including claims, unpriced change orders, award and incentive fees, liquidated damages and penalties. We consider variable consideration in the development of our project forecasts so that our forecasted revenue reflects the amount of consideration we expect to be probable of recovering without a significant reversal. We estimate the amount of revenue to be recognized on variable consideration using the expected value method (i.e., the sum of probability-weighted amounts) or the most likely amount method, whichever offers better prediction. Warranties. We generally provide limited duration warranties for work performed under our contracts. Historically, warranty claims have not resulted in material costs incurred, and any estimated costs for warranties are included in the individual project cost estimates for purposes of accounting for long-term contracts. Practical Expedients. If we have a right to consideration from a customer in an amount that corresponds directly with the value of our performance completed to date (a service contract in which we bill a fixed amount for each hour of service provided), we recognize revenue in the amount to which we have a right to invoice for services performed. We do not adjust the contract price for the effects of a significant financing component where, at contract inception, the period between service provision and customer payment will be one year or less. We exclude from the measurement of the transaction price all taxes assessed by governmental authorities that are collected by us from our customers (use taxes, value added taxes, some excise taxes).
Project Estimates	Project Estimates Due to the nature of our industry, there is significant complexity in our estimation of total expected revenue and cost, for which we must make significant judgments. Our contracts with our customers may contain award fees, incentive fees, liquidated damages or other provisions that can either increase or decrease the contract price to arrive at estimated revenue. These variable amounts generally are earned upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. We estimate variable consideration at the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent it is probable we will realize that amount. Our estimates of variable consideration and our determination of its inclusion in project revenue for accounting purposes are based on an assessment of our anticipated performance and other information that may be available to us. At a project level, we have specific practices and procedures to review our estimate of total revenue and cost. Each project team reviews the progress and execution of our performance obligations, which impact the project’s accounting outcome. As part of this process, the project team reviews information such as any outstanding key contract matters, progress towards completion and the related program schedule and identified risks and opportunities. The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our project estimates, which can change from period to period due to a variety of factors including: • Complexity in original design; • Extent of changes from original design; • Different site conditions than assumed in our bid; • The productivity, availability and skill level of labor; • Weather conditions when executing a project; • The technical maturity of the technologies involved; • Length of time to complete the project; • Availability and cost of equipment and materials; • Subcontractor and joint venture partner performance; • Expected costs of warranties; and • Our ability to recover for additional contract costs.
Contract Assets and Liabilities	Contract Assets and Liabilities Contract assets represent revenue recognized in excess of amounts billed and include unbilled receivables (typically for cost reimbursable contracts) and contract work in progress (typically for fixed-price contracts). Unbilled receivables, which
Segment Reporting	Segment Reporting Management evaluates segment performance based on segment profit. We incur cost and expenses and hold certain assets at the corporate level which relate to our business as a whole. Certain of these amounts have been charged to our business segments by various methods, largely on the basis of usage. Total assets not allocated to segments and held in "Corporate and other" primarily include cash, marketable securities, income-tax related assets, pension assets, deferred compensation trust assets and corporate property, plant and equipment. Segment profit is an earnings measure that we utilize to evaluate and manage our business performance. Segment profit is calculated as revenue less cost of revenue and earnings attributable to NCI.
Variable Interest Entities	Variable Interest Entities We assess our partnerships and joint ventures at inception to determine if any meet the qualifications of a VIE. We consider a partnership or joint venture a VIE if it has any of the following characteristics: (a) the total equity investment is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or their rights to receive the expected residual returns of the entity, and substantially all of the entity's activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events, we reassess our initial determination of whether the partnership or joint venture is a VIE. The majority of our partnerships and joint ventures qualify as VIEs because the total equity investment is typically nominal and not sufficient to permit the entity to finance its activities without additional subordinated financial support. We also perform a qualitative assessment of each identified VIE to determine if we are its primary beneficiary. We conclude that we are the primary beneficiary and consolidate the VIE if we have both: (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. We consider the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining if we are the primary beneficiary. We also consider all parties that have direct or implicit variable interests when determining whether we are the primary beneficiary. Management's assessment of whether we are the primary beneficiary of a VIE is continuously performed.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents include securities with maturities of three months or less at the date of purchase.
Marketable Securities	Marketable Securities Marketable securities consist of time deposits placed with investment grade banks with original maturities greater than three months, which are typically held-to-maturity because we have the intent and ability to hold them until maturity. Held-to-maturity securities are carried at amortized cost. The cost of securities sold is determined by using the specific identification method. Marketable securities are assessed at least annually for other-than-temporary impairment.
Research and Development	Research and Development We have a controlling interest in NuScale, a research and development operation associated with the licensing and commercialization of SMR technology. Since May 2014, NuScale has been receiving reimbursement from the DOE for certain qualified expenditures under cost-sharing award agreements that require NuScale to use the DOE funds to cover engineering costs associated with SMR design development and certification. Costs incurred by NuScale are expensed as incurred, net of qualifying DOE reimbursements, and reported in "Cost of revenue". The U.S. Nuclear Regulatory Commission approved NuScale's design certification application in August 2020. Aside from NuScale, we generally do not engage in significant research and development activities.
Property, Plant and Equipment	Property, Plant and EquipmentProperty, plant and equipment is recorded at cost. Leasehold improvements are amortized over the shorter of their economic lives or the lease terms. Depreciation is calculated using the straight-line method over the following ranges of estimated useful service lives, in years
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill and intangible assets with indefinite lives are not amortized but are subject to at least annual impairment tests during the fourth quarter. For impairment testing, goodwill is allocated to the applicable reporting units based on the current reporting structure. We may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of each reporting unit is less than its carrying amount. If so, we perform a quantitative test, and if the carrying amount of a reporting unit exceeds its fair value, we recognize an impairment loss. Intangible assets with indefinite lives are impaired if their carrying value exceeds their fair value. In-process research and development associated with our investment in NuScale is considered indefinite lived until the related technology is available for commercial use. Interim impairment testing of goodwill and intangible assets is performed if indicators of potential impairment exist. Such indicators may include the results of operations of certain businesses and geographies and the performance of the company stock price. Intangible assets with finite lives are amortized on a straight-line basis over their useful lives.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in our financial statements or tax filings. We evaluate the realizability of our deferred tax assets and record a valuation allowance to reduce deferred tax assets to amounts that are more likely than not to be realized. The factors used to assess the likelihood of realization are our forecast of future taxable income and available tax planning strategies that could be implemented to realize such assets. Failure to achieve forecasted taxable income could affect the ultimate realization of deferred tax assets and could adversely impact our future effective tax rate. Income tax positions are recognized when they meet a more-likely-than-not recognition threshold. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized upon such determination. We recognize potential interest and penalties related to unrecognized tax positions as a component of income tax expense. Judgment is required in determining the provision for income taxes as we consider our worldwide taxable earnings and the impact of the continuing audit process conducted by various tax authorities. The final outcome of any audits could differ materially from amounts recognized by the company. We account for the GILTI effects in the period that is subject to such tax.
Derivatives and Hedging	Derivatives and Hedging We may attempt to limit foreign currency exposure in most of our contracts by denominating contract revenue in the currencies in which cost is incurred. Certain financial exposure, which includes currency and commodity price risk associated with engineering and construction contracts, currency risk associated with monetary assets and liabilities denominated in nonfunctional currencies and risk associated with interest rate volatility, may subject us to earnings volatility. We may implement a hedging strategy utilizing derivatives instruments to mitigate such risk. All derivatives are recorded at fair value. The change in the fair value of the derivative is offset against the change in the fair value of the underlying asset or liability through earnings. To a lesser extent, we also utilize cash flow hedges. We formally document our hedge relationships at inception and subsequently assess hedge effectiveness qualitatively, unless the hedge relationship is no longer highly effective. For cash flow hedges, the change in fair value is recorded as a component of AOCI and is reclassified into earnings when the hedged item settles. In certain limited circumstances, foreign currency payment provisions could be deemed embedded derivatives. If an embedded foreign currency derivative is identified, the derivative is bifurcated from the host contract and the change in fair value is recognized through earnings. We maintain master netting arrangements with certain counterparties to facilitate the settlement of derivative instruments; however, we report the fair value of derivatives on a gross basis.
Concentrations of Credit Risk	Concentrations of Credit Risk Accounts receivable and all contract work in progress are from clients in various industries and locations throughout the world. Most contracts require payments as the projects progress or, in certain cases, advance payments. We generally do not require collateral, but in most cases can place liens against the project assets or terminate the contract, if a material default occurs. We evaluate the counterparty credit risk as part of our project risk review process and in determining the appropriate level of reserves. We maintain reserves for potential credit losses and generally such losses have been minimal and within management's estimates. We have cash and marketable securities on deposit with major banks throughout the world. Such deposits are placed with high quality institutions and the amounts invested in any single institution are limited to the extent possible in order to minimize concentration of counterparty credit risk. Our counterparties for derivatives are large financial institutions selected based on profitability, strength of balance sheet, credit ratings and capacity for timely payment of financial commitments. There are no significant concentrations of credit risk with any individual counterparty related to our derivative contracts. We monitor the credit quality of our counterparties and establish reserves for any significant credit risk losses.
Stock-Based Plans	Stock-Based Plans Our stock plans provide for grants of nonqualified or incentive stock options, RSUs, restricted stock and performance-based award units, including VDI units. All grants of stock options and RSUs as well as performance-based units awarded to Section 16 officers in 2021, 2020 and 2019 can only be settled in company stock and are accounted for as equity awards. All expense under stock-based awards is recognized based on the fair values of the awards. Stock option awards have grant exercise prices equal to the grant date market price of the company's stock. The fair value of grants of RSUs and restricted stock is determined using the closing price of our common stock on the date of grant but may be discounted for any significant post-vest holding periods. The grant date fair value of performance-based award units is determined by adjusting the closing price of the company's common stock on the date of grant for any post-vest holding period discounts and for the effect of market conditions, when applicable. Stock-based compensation expense is generally recognized over the required service period, or over a shorter period when employee retirement eligibility is a factor.
Leases	Leases We recognize right-of-use assets and lease liabilities for leases with terms greater than 12 months or leases that contain a purchase option that is reasonably certain to be exercised. Leases are classified as either finance or operating leases. This classification dictates whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. Our right-of use assets and lease liabilities primarily relate to office facilities, equipment used in connection with long-term construction contracts and other personal property. Certain of our facility and equipment leases include one or more options to renew, with renewal terms that can extend the lease term up to 10 years. The exercise of lease renewal options is at our discretion. Renewal periods are included in the expected lease term if they are reasonably certain of being exercised by us. Certain leases also include options to purchase the leased property. None of our lease agreements contain material residual value guarantees or material restrictions or covenants. Long-term leases (leases with terms greater than 12 months) are recorded as liabilities at the present value of the minimum lease payments not yet paid. We use our incremental borrowing rate to determine the present value of the lease when the rate implicit in the lease is not readily determinable. Certain lease contracts contain nonlease components such as maintenance, utilities, fuel and operator services. We recognize both the lease component and nonlease components as a single lease component for all of its right-of-use assets. From time to time, certain service or purchase contracts may contain an embedded lease.
Recent Accounting Pronouncements	Accounting Pronouncements Implemented During 2021 In the first quarter of 2021, we adopted ASU 2020-06, “Accounting for Convertible Instruments and Contracts in an Entity's Own Equity,” which simplifies accounting for convertible instruments and the application of the derivatives scope exception for contracts in our own equity. ASU 2020-06 eliminates two of the three models in the prior guidance that required separating embedded conversion features from convertible instruments and also eliminates some of the requirements for equity classification. ASU 2020-06 also addresses how convertible instruments are accounted for in the diluted EPS calculation. The adoption did not have any impact on our financial statements.

Carrying amounts approximate fair value. (2) The carrying amounts of these time deposits approximate fair value because of the short-term maturity of these instruments. Amortized cost is not materially different from the fair value. (3) Notes receivable are carried at net realizable value which approximates fair value. Factors considered in determining the fair value include the credit worthiness of the borrower, current interest rates, the term of the note and any collateral pledged as security. Notes receivable are periodically assessed for impairment. (4) The fair value of the Senior Notes was estimated based on quoted market prices and Level 2 inputs. (5) Other borrowings represent bank loans and other financing arrangements which mature within one year. The carrying amount of borrowings under these arrangements approximates fair value because of the short-term maturity.
