Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation These financial statements do not include footnotes and certain financial information normally presented annually under GAAP, and therefore, should be read in conjunction with our 2019 10-K. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end. Although such estimates are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available including considerations for the potential impacts of COVID-19, our reported results of operations may not necessarily be indicative of results that we expect for the full year. The financial statements included herein are unaudited. In management's opinion, they contain all adjustments of a normal recurring nature which are necessary to present fairly our financial position and our operating results as of and for the interim periods presented. All significant intercompany transactions of consolidated subsidiaries are eliminated. Certain amounts in 2019 have been reclassified to conform to the 2020 presentation, which includes the segregation of Disc Ops and assets and liabilities held for sale. Segment operating information for 2019 has been recast to reflect the current composition of our reportable segments. Management has evaluated all material events occurring subsequent to September 30, 2020 through the filing date of this Q3 2020 10-Q.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting pronouncements relevant to our business that were implemented by us during the first nine months of 2020 On January 1, 2020, we adopted ASC Topic 326, “Financial Instruments - Credit Losses,” which replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of information to estimate credit losses. The new guidance requires financial assets measured at amortized cost to be presented at the net amount expected to be collected. We adopted ASC 326 using the modified retrospective method, and accordingly, the new guidance was applied to financial assets measured at amortized cost (primarily accounts receivable and contract assets) that existed as of January 1, 2020 (the date of initial application). As a result, we recorded additional reserves for credit losses of $2 million and a cumulative effect adjustment to decrease retained earnings by $2 million as of January 1, 2020. The adoption of ASC 326 did not have a material impact on our results of operations or any impact on our cash flows. We utilize a combination of methods for estimating expected credit losses including loss rates, aging schedules and probability-of-default. In evaluating our historical loss rates, accounts receivable and contract assets are pooled into the following categories based on similar risk characteristics: (1) EPC management; (2) government; (3) operations and maintenance; and (4) equipment leasing. Historical loss experience is adjusted for current conditions and reasonable and supportable forecasts, when applicable. Significantly aged receivables are evaluated individually by credit rating. Our reserve for credit losses amounted to $35 million as of both September 30, 2020 and December 31, 2019 . In the first quarter of 2020, we adopted ASU 2019-12, “Simplifying the Accounting for Income Taxes,” which eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The adoption did not have a material impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-18, “Clarifying the Interaction between Topic 808 and Topic 606,” which clarifies that certain transactions between participants in a collaborative arrangement should be accounted for under ASC 606 when the counterparty is a customer. The adoption did not have any impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-17, “Targeted Improvements to Related Party Guidance for Variable Interest Entities,” which amends the guidance for determining whether a decision-making fee is a variable interest. The adoption did not have any impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which requires customers in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. The adoption did not have any impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-13, “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement,” which amends certain disclosure requirements for fair value measurements. For example, public companies will now be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The adoption did not have any impact on our financial statements, but we have made additional disclosures related to the range and weighted average rates used to develop significant inputs for nonrecurring Level 3 measurements. Accounting pronouncements relevant to our business that have not yet been implemented In August 2018, the FASB issued ASU 2018-14, “Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans,” which amends certain disclosure requirements related to defined benefit pension and other postretirement plans. ASU 2018-14 becomes effective for us on January 1, 2021, but we do not expect its adoption to have any impact on our financial statements.

Segment profit for the 2019 Period included charges totaling $240 million (or $1.40 per share) for cost growth on an offshore project. Additional charges totaling $87 million (or $0.50 per share) for the 2019 Period resulted from schedule-driven cost growth and client and subcontractor negotiations on two downstream projects and scope reductions on a large upstream project. Pre-contract costs of $26 million (or $0.15 per share) were expensed in the 2019 Period due to our evaluation of the reduced probability of receiving an award. Segment profit during the 2019 Period was also impacted by a charge of $31 million (or $0.22 per share) resulting from the resolution of close-out matters with a customer. There were no similar material charges in 2020. Infrastructure & Power. Segment profit for the 2019 Period included charges totaling $135 million (or $0.74 per share) which included the settlement of client disputes, as well as cost growth related to close-out matters on three lump-sum, gas-fired power plant projects that were substantially complete as of December 31, 2019. Segment profit during the 2019 Period also included charges totaling $55 million (or $0.30 per share) resulting from late engineering changes and schedule-driven cost growth, as well as negotiations with clients and subcontractors on pending change orders, for several infrastructure projects. There were no similar material charges in 2020. Diversified Services. Intercompany revenue for Diversified Services, excluded from the amounts shown above, was $61 million and $200 million for the 2020 Quarter and 2020 Period, respectively, and $81 million and $253 million for the 2019 Quarter and 2019 Period, respectively. Other . Segment loss for both the 2019 Quarter and 2019 Period included charges totaling $59 million (or $0.42 per share) resulting from forecast revisions for cost growth on the Warren project.

Restructuring and Related Activities [Abstract]
Impairment, Restructuring and Other Exit Costs	Impairment, Restructuring and Other Exit Costs Restructuring and Other Exit Costs During 2019, we initiated a broad restructuring plan designed to optimize costs and improve operational efficiency. These efforts primarily relate to the rationalization of resources, investments, real estate and overhead across various geographies, as well as the liquidation of certain components of the AMECO business that are being excluded from sale. We expect that our planned restructuring activities will be substantially completed by the end of 2020. Restructuring costs of $5 million , primarily related to severance, were recognized during the 2020 Period. Restructuring costs of $44 million and $98 million recognized during the 2019 Quarter and 2019 Period, respectively, primarily related to severance and asset impairment expense. Restructuring information is summarized as follows: (in millions) Recognized to Date Total Cost Expected to be Incurred Restructuring and other exit costs: Severance $ 68.9 $ 70.0 Asset impairments 90.4 90.4 Entity liquidation costs (including the recognition of cumulative translation adjustments) 83.7 85.0 Other exit costs 2.1 5.0 Total restructuring and other exit costs $ 245.1 $ 250.4 A reconciliation of the restructuring liabilities follows: (in thousands) Severance Lease Exit Costs Other Total Balance as of December 31, 2019 $ 46,303 $ 570 $ 307 $ 47,180 Restructuring charges recognized during the period 4,219 102 737 5,058 Cash payments / settlements during the period (21,366 ) (640 ) (552 ) (22,558 ) Currency translation 426 — (1 ) 425 Balance as of September 30, 2020 $ 29,582 $ 32 $ 491 $ 30,105 Impairment Impairment expense is summarized as follows: Nine Months Ended (in thousands) 2020 2019 Impairment expense: Goodwill associated with the Diversified Services reporting unit $ 168,568 $ — Intangible customer relationships associated with the Stork business 26,671 33,657 Equity method investments in the Energy & Chemicals business 86,096 256,769 Information technology assets 16,269 — Total impairment expense $ 297,604 $ 290,426 2020 Impairment Certain of our businesses have been adversely affected by the economic impacts of the outbreak of COVID-19 and the steep decline in commodity prices that occurred in the first quarter of 2020. These events have caused significant uncertainty, economic volatility and disruption, which have impacted and may continue to impact our operations. We have experienced, and may continue to experience, reductions in demand for certain of our services and the delay or abandonment of ongoing or anticipated projects due to our clients’, suppliers’ and other third parties’ diminished financial condition or financial distress, as well as governmental budget constraints. These impacts are expected to continue or worsen if stay-at-home, social distancing, travel restrictions and other similar orders or restrictions remain in place for an extended period of time or are re-imposed after being relaxed. Significant uncertainty still exists concerning the magnitude of the impact and duration of these events. Because of these events and their impact on our operations, we performed interim impairment testing of our goodwill, intangible assets and investments and recognized the above impairment expense during the first quarter of 2020, which were included in “Impairment, restructuring and other exit costs.” No additional impairment expense was recognized during the second or third quarters of 2020. As part of our assessment of goodwill, 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. 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% . The valuation of the equity method investments utilized unobservable Level 3 inputs based on the forecast of anticipated volumes and overhead absorption in a cyclical business. 2019 Impairment During the 2019 Quarter, we recognized impairment expense on our intangible customer relationships associated with the Stork business. We also evaluated our significant investments and determined that certain of our investments were impaired as of September 30, 2019 .

The effective tax rate for all periods was unfavorably impacted by foreign income tax rates that exceed the U.S. statutory rate of 21%, as well as the establishment or augmentation of valuation allowances against foreign tax credits and certain losses. The effective tax rate for the 2020 Period was favorably impacted by the release of valuation allowances and rate benefits resulting from the carryback of our 2019

Partnerships and Joint Ventures	9 Months Ended

Partnerships and Joint Ventures
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. Accounts receivable related to work performed for unconsolidated partnerships and joint ventures included in “Accounts and notes receivable, net” was $191 million and $149 million as of September 30, 2020 and December 31, 2019 , respectively. During the first quarter of 2020, we evaluated our significant investments and determined that certain of our investments were impaired. As a result, we recognized impairment expense of $86 million . 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 have a scheduled funding commitment to the joint venture of $26 million due at the end of 2020. During the 2020 Period, we sold our 50% ownership interest in Sacyr Fluor and recognized a loss on sale of $11 million , which was included in Energy & Chemicals' segment profit. 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. The net carrying value of unconsolidated VIEs (classified under both "Investments” and “Other accrued liabilities”) was a net asset of $241 million and $217 million as of September 30, 2020 and December 31, 2019 , respectively. Some of our VIEs have debt; however, such debt is typically non-recourse to us. 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 September 30, 2020 for the unconsolidated VIEs were $77 million . In some cases, we are required to consolidate VIEs. As of September 30, 2020 , the carrying values of the assets and liabilities associated with the operations of the consolidated VIEs were $1.3 billion and $816 million , respectively. As of December 31, 2019 , the carrying values of the assets and liabilities associated with the operations of the consolidated VIEs were $1.1 billion and $798 million , respectively. 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.

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 Corporation 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 business, 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. 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. Since September 2018, nine 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 Corporation is named as a nominal defendant in the actions. These derivative actions purport to assert claims on behalf of Fluor Corporation 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 have been consolidated and stayed until our motion to dismiss is ruled upon in the securities class action matter. 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. 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 Corporation 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 a charge 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 parties’ agreements. 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. Accordingly, we have not recorded a charge 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 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. 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 a charge as a result of these claims. Purple Line Transit Partners, LLC (“PLTP”) entered into a Public Private Partnership Agreement (“PPPA”) with the Maryland Department of Transportation and the Maryland Transit Administration (together, the “State”) for the finance, design, construction, and operation of the Purple Line Project, a new light rail line in Maryland (the “Project”). PLTP is a limited liability company in which Fluor has a 15% membership interest. PLTP entered into an Amended and Restated Design-Build Contract (the “DB Contract”) with Purple Line Transit Constructors, LLC (“PLTC”) as design-build contractor to perform PLTP’s design and construction obligations under the PPPA on a back-to-back basis. PLTC is a limited liability company in which Fluor has a 50% membership interest. The design and construction of the Project was significantly delayed by more than two and a half years due to events outside of PLTP or PLTC’s control. The PPPA contained a provision allowing PLTP the unconditional right to terminate the PPPA if certain events delayed the design and construction of the Project by 365 days or more. The DB Contract contained a similar provision allowing PLTC to terminate the DB Contract. Because of significant Project delays, in excess of 365 days, on May 1, 2020, PLTC gave notice to PLTP of PLTC’s intent to terminate the DB Contract. Upon receiving PLTC’s notice, on June 23, 2020, PLTP exercised its unconditional right to terminate the PPPA. The State has challenged PLTP’s termination of the PPPA and commenced a lawsuit in Maryland state court against PLTP alleging breach of the PPPA. We believe that PLTP and PLTC’s terminations of the PPPA and DB Contract, respectively, were justified and are vigorously defending against the State’s lawsuit. Other Matters We have made claims arising from the performance under our contracts. We periodically evaluate our positions and the amounts recognized with respect to all of our claims and back charges. As of September 30, 2020 and December 31, 2019 , we had recorded $214 million and $198 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 also had recorded disputed back charges to suppliers or subcontractors totaling $1 million and $2 million as of September 30, 2020 and December 31, 2019 , respectively. We believe the ultimate recovery of amounts related to these claims and back charges is probable in accordance with GAAP. From time to time, we enter into significant contracts with the U.S. government and its agencies. Government contracts are subject to audits and investigations 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, based upon present information available to us, that our reserves with respect to future environmental cost are adequate and such future cost will not have a material effect on our consolidated financial position, results of operations or liquidity. On February 18, 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. On April 30, 2020, the Corporation received a subpoena 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. We are coordinating responses to the SEC and DOJ and cooperating in providing the requested documents and information, which efforts are ongoing.

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. The performance guarantees have various expiration dates ranging from mechanical completion of the project 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 September 30, 2020 . Amounts that may be required to be paid in excess of estimated cost to complete contracts in progress are not estimable. 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. The performance guarantee obligation was not material as of September 30, 2020 or December 31, 2019

Debt Disclosure [Abstract]
Debt and Letters of Credit	Debt and Letters of Credit As of September 30, 2020 , letters of credit totaling $384 million were outstanding under our committed lines of credit, which consist of a $1.7 billion Revolving Loan and Letter of Credit Facility and a $1.8 billion Revolving Loan and Letter of Credit Facility. Both facilities mature in February 2022. These credit facilities contain customary financial and restrictive covenants, including a debt-to-capitalization ratio that cannot exceed 0.6 to 1.0 and a limitation on the aggregate amount of debt of the greater of $750 million or €750 million for our subsidiaries. As of September 30, 2020 , our financial covenants limit our borrowings to approximately $654 million under the committed lines of credit, although no amounts were drawn. Borrowings under both facilities, which may be denominated in USD, EUR, GBP or CAD, bear interest at rates based on the Eurodollar Rate or an alternative base rate, plus an applicable borrowing margin. Due to the delays in the preparation of our financial statements for the quarter ended September 30, 2020 , we were not in compliance with the reporting deadlines under the committed lines of credit. We have entered into amendments to extend the deadline to provide financial information for the third quarter until December 31, 2020. By completing the filing of the Q3 2020 10-Q and submitting other information to the lenders, we will have satisfied all interim 2020 reporting obligations under the committed lines of credit. As of September 30, 2020 , letters of credit totaling $792 million were also outstanding under uncommitted lines of credit. In August 2020, we received a notice of default from the trustee under the indenture governing all of our Senior Notes arising from the delay in the filing of the 2019 10-K and the Q1 2020 10-Q. In September 2020, we received a second notice of default arising from the delay in the filing of the Q2 2020 10-Q. Upon the filing of the 2019 10-K on September 25, 2020, the Q1 2020 10-Q on October 22, 2020 and the Q2 2020 10-Q on November 12, 2020, we have now satisfied these reporting requirements.

These investments, which are trading securities, represent the net asset value of the close of business at the end of the period based on the last trade or official close of an active market or exchange. (2) Foreign currency and commodity derivatives are estimated using pricing models with market-based inputs, which take into account the present value of estimated future cash flows. We have measured assets and liabilities held for sale and certain other impaired assets at fair value on a nonrecurring basis.

Carrying amounts approximate fair value. (2) Cash equivalents consist of held-to-maturity time deposits with maturities of three months or less at the date of purchase. The carrying amounts of these time deposits approximate fair value because of the short-term maturity of these instruments. (3) Marketable securities consist of held-to-maturity time deposits with original maturities greater than three months that will mature within one year. 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. (4) 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. (5) The fair value of the Senior Notes was estimated based on the quoted market prices for these issues as of the end of the period. (6) Other borrowings primarily 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.

Share-based Payment Arrangement [Abstract]
Stock-Based Plans	Stock-Based Plans Our executive and director stock-based compensation plans are described more fully in the 2019 10-K. In the 2020 and 2019 Periods, RSUs totaling 1,098,926 and 1,065,139 , respectively, were granted to executives or directors (2019 Period only) at weighted-average grant date fair values of $8.81 per share and $36.45 per share, respectively. RSUs granted to executives in 2020 and 2019 generally vest over three years . RSUs granted to directors in 2019 vested immediately and are subject to a post-vest holding period of three years . The fair value of RSUs represents the closing price of our common stock on the date of grant discounted for the post-vest holding period, when applicable. There were no RSUs awarded to directors during the 2020 Period. Instead, RSUs were awarded to directors in November 2020 following the annual shareholder meeting. Stock options for the purchase of 672,309 shares at a weighted-average exercise price of $8.81 per share and 392,841 shares at a weighted-average exercise price of $29.03 per share were awarded to executives during the 2020 and 2019 Periods, respectively. The exercise price of options represents the closing price of our common stock on the date of grant. The options granted in 2020 and 2019 generally vest over three years and expire ten years after the grant date. Performance-based award units totaling 1,156,365 and 350,532 were awarded to executives during the 2020 and 2019 Periods, respectively. These awards generally vest after a period of three years and contain annual performance conditions for each of the three 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. During the 2020 Period, units totaling 385,455 , 116,844 and 68,866 under the 2020, 2019 and 2018 performance award plans, respectively, were granted at weighted-average grant date fair values of $9.05 per share, $9.77 per share and $10.75

Derivatives and Hedging

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging We 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 the company to earnings volatility. We may utilize derivatives instruments or hedging instruments to mitigate such risk. Our hedging instruments are designated as either fair value or cash flow hedges. We formally document our hedge relationships at inception, including identification of the hedging instruments and the hedged items, our risk management objectives and strategies for undertaking the hedge transaction, and the initial quantitative assessment of the hedging instrument's effectiveness in offsetting changes in the fair value of the hedged items. We subsequently assess hedge effectiveness qualitatively, unless the hedge relationship is no longer highly effective. All hedging instruments are recorded at fair value. For fair value hedges, the change in fair value is offset against the change in the fair value of the underlying asset or liability through earnings. 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. For derivatives that are not designated or do not qualify as hedging instruments, 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. 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. Derivatives Designated as Hedges As of September 30, 2020 , we had total gross notional amounts of $754 million of foreign currency contracts outstanding (primarily related to the Canadian Dollar, Chinese Yuan, British Pound, Euro, Indian Rupee and Philippine Peso) that were designated as hedging instruments. The foreign currency contracts are of varying duration, none of which extend beyond June 2024. There were no commodity contracts outstanding that were designated as hedging instruments as of September 30, 2020 .

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations We expect to complete the sale of the AMECO equipment business, which is reported in Disc Ops, within the first half of 2021. The assets and liabilities of the AMECO business are classified as held for sale. Due to the impact of COVID-19 and the steep decline in oil prices on the AMECO business during the first quarter of 2020, we recognized impairment expense of $100 million , of which $12 million related to goodwill, to reduce the AMECO assets to their fair value less cost to sell. The fair value of the AMECO assets were determined using a combination of observable level 2 inputs, including indicative offers and ongoing negotiations for the related assets. In August 2020, we sold our AMECO equipment business in Jamaica for $18 million and recognized a loss of $1 million . The operations of the AMECO business in Jamaica were included in Disc Ops through the date of sale.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Accounting pronouncements relevant to our business that were implemented by us during the first nine months of 2020 On January 1, 2020, we adopted ASC Topic 326, “Financial Instruments - Credit Losses,” which replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of information to estimate credit losses. The new guidance requires financial assets measured at amortized cost to be presented at the net amount expected to be collected. We adopted ASC 326 using the modified retrospective method, and accordingly, the new guidance was applied to financial assets measured at amortized cost (primarily accounts receivable and contract assets) that existed as of January 1, 2020 (the date of initial application). As a result, we recorded additional reserves for credit losses of $2 million and a cumulative effect adjustment to decrease retained earnings by $2 million as of January 1, 2020. The adoption of ASC 326 did not have a material impact on our results of operations or any impact on our cash flows. We utilize a combination of methods for estimating expected credit losses including loss rates, aging schedules and probability-of-default. In evaluating our historical loss rates, accounts receivable and contract assets are pooled into the following categories based on similar risk characteristics: (1) EPC management; (2) government; (3) operations and maintenance; and (4) equipment leasing. Historical loss experience is adjusted for current conditions and reasonable and supportable forecasts, when applicable. Significantly aged receivables are evaluated individually by credit rating. Our reserve for credit losses amounted to $35 million as of both September 30, 2020 and December 31, 2019 . In the first quarter of 2020, we adopted ASU 2019-12, “Simplifying the Accounting for Income Taxes,” which eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The adoption did not have a material impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-18, “Clarifying the Interaction between Topic 808 and Topic 606,” which clarifies that certain transactions between participants in a collaborative arrangement should be accounted for under ASC 606 when the counterparty is a customer. The adoption did not have any impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-17, “Targeted Improvements to Related Party Guidance for Variable Interest Entities,” which amends the guidance for determining whether a decision-making fee is a variable interest. The adoption did not have any impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which requires customers in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. The adoption did not have any impact on our financial statements. In the first quarter of 2020, we adopted ASU 2018-13, “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement,” which amends certain disclosure requirements for fair value measurements. For example, public companies will now be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The adoption did not have any impact on our financial statements, but we have made additional disclosures related to the range and weighted average rates used to develop significant inputs for nonrecurring Level 3 measurements. Accounting pronouncements relevant to our business that have not yet been implemented In August 2018, the FASB issued ASU 2018-14, “Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans,” which amends certain disclosure requirements related to defined benefit pension and other postretirement plans. ASU 2018-14 becomes effective for us on January 1, 2021, but we do not expect its adoption to have any impact on our financial statements.

Carrying amounts approximate fair value. (2) Cash equivalents consist of held-to-maturity time deposits with maturities of three months or less at the date of purchase. The carrying amounts of these time deposits approximate fair value because of the short-term maturity of these instruments. (3) Marketable securities consist of held-to-maturity time deposits with original maturities greater than three months that will mature within one year. 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. (4) 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. (5) The fair value of the Senior Notes was estimated based on the quoted market prices for these issues as of the end of the period. (6) Other borrowings primarily 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.
