Principles of Consolidation

Principles of Consolidation
Principles of Consolidation	(1) Principles of Consolidation The Condensed Consolidated Financial Statements do not include footnotes and certain financial information normally presented annually under accounting principles generally accepted in the United States and, therefore, should be read in conjunction with the company’s December 31, 2016 Annual Report on Form 10-K. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year-end. The results of operations for the three and nine months ended September 30, 2017 may not necessarily be indicative of results that can be expected for the full year. The Condensed Consolidated Financial Statements included herein are unaudited; however, they contain all adjustments of a normal recurring nature which, in the opinion of management, are necessary to present fairly its consolidated financial position as of September 30, 2017 and December 31, 2016 and its consolidated results of operations and cash flows for the interim periods presented. All significant intercompany transactions of consolidated subsidiaries are eliminated. Management has evaluated all material events occurring subsequent to the date of the financial statements up to the filing date of this Form 10-Q. The Condensed Consolidated Financial Statements include the financial statements of Stork Holding B.V. (“Stork”) since March 1, 2016, the date of acquisition. See Note 18 for a discussion of the acquisition.

Recent Accounting Pronouncements
Recent Accounting Pronouncements	(2) Recent Accounting Pronouncements New accounting pronouncements implemented by the company during the nine months ended September 30, 2017 are discussed below or in the related notes, where appropriate. In the third quarter of 2017, the company elected to adopt Accounting Standards Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment” before its effective date. ASU 2017-04 removes the second step of the goodwill impairment test, which requires a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Management does not expect the adoption of ASU 2017-04 to have any impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2017, the company adopted ASU 2016-17, “Interests Held through Related Parties That Are Under Common Control” which amends the consolidation requirements that apply to a single decision maker’s evaluation of interests held through related parties that are under common control when it is determining whether it is the primary beneficiary of a variable interest entity. The adoption of ASU 2016-17 did not have any impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2017, the company adopted ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” This ASU is intended to simplify various aspects of accounting for share-based payment awards, including income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows and forfeiture rate calculations. As a result of the adoption of ASU 2016-09, the excess tax benefits and tax deficiencies associated with option exercises and vested share awards are now recognized as income tax benefit or expense in the Condensed Consolidated Statement of Earnings instead of in additional paid-in capital. Additionally, the excess tax benefits are now presented as an operating activity on the Condensed Consolidated Statement of Cash Flows, rather than as a financing activity. ASU 2016-09 also changed the method the company uses to calculate shares for diluted earnings per share (discussed further in Note 7). The company adopted the provision of ASU 2016-09 on a prospective basis; therefore, these changes were effective beginning in the first quarter of 2017. The adoption of ASU 2016-09 did not have a material impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2017, the company adopted ASU 2016-07, “Simplifying the Transition to the Equity Method of Accounting” which eliminates the requirement to retrospectively apply equity method accounting when an investor obtains significant influence over a previously held investment. The adoption of ASU 2016-07 did not have any impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2017, the company adopted ASU 2016-05, “Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.” This ASU clarifies that the novation of a derivative contract in a hedge accounting relationship does not, in and of itself, require dedesignation of that hedge accounting relationship. The adoption of ASU 2016-05 did not have any impact on the company’s financial position, results of operations or cash flows. New accounting pronouncements requiring implementation in future periods are discussed below. In August 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” This ASU amends the FASB’s hedge accounting model to enable entities to better portray their risk management activities in the financial statements. ASU 2017-12 expands an entity’s ability to hedge nonfinancial and financial risk components and eliminates the requirement to separately measure and report hedge ineffectiveness. ASU 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. Management does not expect the adoption of ASU 2017-12 to have a material impact on the company’s financial position, results of operations or cash flows. In May 2017, the FASB issued ASU 2017-09, “Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting,” which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. Entities should apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. ASU 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted and prospective application is required. Management does not expect the adoption of ASU 2017-09 to have a material impact on the company’s financial position, results of operations or cash flows. In March 2017, the FASB issued ASU 2017-08, “Premium Amortization on Purchased Callable Debt Securities.” For purchased callable debt securities held at a premium, ASU 2017-08 requires entities to amortize the premium to the earliest call date rather than over the contractual life of the instrument. Therefore, entities will no longer recognize a loss in earnings on the unamortized premium upon the issuer’s exercise of a call. ASU 2017-08 is effective for interim and annual reporting periods beginning after December 15, 2018. Management does not expect the adoption of ASU 2017-08 to have a material impact on the company’s financial position, results of operations or cash flows. In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” ASU 2017-07 requires employers to present the service cost component of net periodic benefit cost in the same income statement line item as other compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are required to be presented separately from the service cost component. ASU 2017-07 is effective for interim and annual reporting periods beginning after December 15, 2017. Management does not expect the adoption of ASU 2017-07 to have a material impact on the company’s financial position, results of operations or cash flows. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. ASU 2017-01 requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. ASU 2017-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Management does not expect the adoption of ASU 2017-01 to have a material impact on the company’s financial position, results of operations or cash flows. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force).” ASU 2016-18 requires an entity to include in its cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. ASU 2016-18 is effective for interim and annual reporting periods beginning after December 15, 2017. Management does not expect the adoption of ASU 2016-18 to have a material impact on the company’s financial position, results of operations or cash flows. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 amends the guidance in Accounting Standards Codification (“ASC”) 230, which often requires judgment to determine the appropriate classification of cash flows as operating, investing or financing activities and has resulted in diversity in practice in how certain cash receipts and cash payments are classified. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017 and should be applied on a retrospective basis. Management does not expect the adoption of ASU 2016-15 to have a material impact on the company’s cash flows. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” The amendments in this ASU replace the incurred loss impairment methodology in current practice with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. Management does not expect the adoption of ASU 2016-13 to have a material impact on the company’s financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, “Leases: Amendments to the FASB Accounting Standards Codification,” which amends the existing guidance on accounting for leases. This ASU requires the recognition of lease assets and lease liabilities on the balance sheet, and the disclosure of key information about leasing arrangements. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted and modified retrospective application is required for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. Management is currently evaluating the impact of adopting ASU 2016-02 on the company’s financial position, results of operations or cash flows. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments — Overall — Recognition and Measurement of Financial Assets and Financial Liabilities.” This ASU requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to recognize any changes in fair value in net income unless the investments qualify for a practicability exception. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Management does not expect the adoption of ASU 2016-01 to have a material impact on the company’s financial position, results of operations or cash flows. Revenue Recognition In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 outlines a five-step process for revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards, and also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. Major provisions include determining which goods and services are distinct and represent separate performance obligations, how variable consideration (which may include change orders and claims) is recognized, whether revenue should be recognized at a point in time or over time and ensuring the time value of money is considered in the transaction price. As a result of the deferral of the effective date in ASU 2015-14, “Revenue from Contracts with Customers — Deferral of the Effective Date,” the company will now be required to adopt ASU 2014-09 for interim and annual reporting periods beginning after December 15, 2017. ASU 2014-09 can be applied either retrospectively to each prior period presented or as a cumulative-effect adjustment as of the date of adoption. In March 2016, the FASB issued ASU 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” which clarifies the principal versus agent guidance in ASU 2014-09. ASU 2016-08 clarifies how an entity determines whether to report revenue gross or net based on whether it controls a specific good or service before it is transferred to a customer. ASU 2016-08 also reframes the indicators to focus on evidence that an entity is acting as a principal rather than as an agent. In April 2016, the FASB issued ASU 2016-10, “Identifying Performance Obligations and Licensing,” which amends certain aspects of ASU 2014-09. ASU 2016-10 amends how an entity should identify performance obligations for immaterial promised goods or services, shipping and handling activities and promises that may represent performance obligations. ASU 2016-10 also provides implementation guidance for determining the nature of licensing and royalties arrangements. In May 2016, the FASB issued ASU 2016-12, “Narrow-Scope Improvements and Practical Expedients,” which also clarifies certain aspects of ASU 2014-09 including the assessment of collectability, presentation of sales taxes, treatment of noncash consideration, and accounting for completed contracts and contract modifications at transition. In December 2016, the FASB issued ASU 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers,” which allows an entity to determine the provision for loss contracts at either the contract level or the performance obligation level as an accounting policy election. In February 2017, the FASB issued ASU 2017-05, “Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets,” which clarifies that the scope and application of ASC 610-20 on accounting for the sale or transfer of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales, applies only when the asset (or asset group) does not meet the definition of a business. ASU 2017-05, 2016-20, 2016-12, 2016-10 and 2016-08 are effective upon adoption of ASU 2014-09. Management is currently evaluating the impact of adopting ASU 2014-09, 2016-08, 2016-10, 2016-12, 2016-20 and 2017-05 on the company’s financial position, results of operations, cash flows, related disclosures and internal controls. Adoption of these ASUs is expected to affect the manner in which the company determines the unit of account for its projects (i.e., performance obligations). Under existing guidance, the company typically segments revenue and margin recognition between the engineering and construction phases of its contracts. Upon adoption, the company expects that the entire engineering and construction contract will typically be a single unit of account (a single performance obligation), which will result in a more constant recognition of revenue and margin over the term of the contract. The company will adopt ASU 2014-09 during the first quarter of 2018. The company expects to adopt this new standard using the modified retrospective method that will result in a cumulative effect adjustment as of the date of adoption.

Change in Accounting Principle
Change in Accounting Principle	(3) Change in Accounting Principle In the third quarter of 2017, the company voluntarily changed the date of its annual goodwill impairment testing for all reporting units previously assessed as of March 1 to October 1. Prior to this change, goodwill impairment testing for certain reporting units was performed as of March 1, while goodwill impairment testing for certain recent acquisitions was performed as of October 1. This voluntary change is preferable as it better aligns the timing of the goodwill impairment testing with the completion of the company’s strategic and annual operating planning process. The voluntary change in accounting principle related to the annual testing date will not delay, accelerate or avoid an impairment charge. This change is not applied retrospectively as it is impracticable to do so because retrospective application would require application of significant estimates and assumptions with the use of hindsight. Accordingly, the change will be applied prospectively.

Income Taxes
Income Taxes	(5) Income Taxes The effective tax rates for the three and nine months ended September 30, 2017 were 31.7 percent and 21.8 percent, respectively. The effective tax rate for the nine month period ended September 30, 2017 reflected a benefit due to a worthless stock deduction for an insolvent foreign subsidiary. The effective tax rates for the three and nine months ended September 30, 2016 reflected the favorable resolution of an IRS audit for tax years 2009-2013 and an increase in the research tax credit. All periods benefit from earnings attributable to noncontrolling interests for which income taxes are not typically the responsibility of the company. The company conducts business globally and, as a result, the company or one or more of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, the company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Canada, the Netherlands, South Africa, the United Kingdom and the United States. Although the company believes its reserves for its tax positions are reasonable, the final outcome of tax audits could be materially different, both favorably and unfavorably. With a few exceptions, the company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 2013.

Earnings Per Share	(7) Earnings Per Share Diluted earnings per share (“EPS”) reflects the assumed exercise or conversion of all dilutive securities using the treasury stock method. As a result of the adoption of ASU 2016-09, the excess tax benefits and tax deficiencies that were previously recorded to additional paid-in capital have been excluded from the hypothetical proceeds used to calculate the repurchase of shares under the treasury stock method beginning in the first quarter of 2017.

Fair Value Measurements

Fair Value Measurements
Fair Value Measurements	(8) Fair Value Measurements The fair value hierarchy established by ASC 820, “Fair Value Measurement,” 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 The company measures and reports assets and liabilities at fair value utilizing pricing information received from third parties. The company performs procedures to verify the reasonableness of pricing information received for significant assets and liabilities classified as Level 2. The following table presents, for each of the fair value hierarchy levels required under ASC 820-10, the company’s assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016: September 30, 2017 December 31, 2016 Fair Value Hierarchy Fair Value Hierarchy (in thousands) Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Cash and cash equivalents (1) $ $ $ $ — $ $ $ — $ — Marketable securities, current (2) — — — — Deferred compensation trusts (3) — — — — Marketable securities, noncurrent (4) — — — — Derivative assets (5) Commodity contracts — — — — Foreign currency contracts — — — — Liabilities: Derivative liabilities (5) Commodity contracts $ — $ — $ — $ — $ $ — $ $ — Foreign currency contracts — — — — (1) Consists of registered money market funds and investments in U.S. agency securities with maturities of three months or less at the date of purchase. The fair value of the money market funds represents the net asset value of the shares of such funds as of the close of business at the end of the period. The fair value of the investments in U.S. agency securities is based on pricing models, which are determined from a compilation of primarily observable market information, broker quotes in non-active markets or similar assets. (2) Consists of investments in U.S. agency securities, U.S. Treasury securities, corporate debt securities and commercial paper with maturities of less than one year that 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. (3) Consists of a registered money market fund, a short-term bond fund and an equity index fund valued at fair value. These investments, which are trading securities, represent the net asset value of the shares of such funds as 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. (4) Consists of investments in U.S. agency securities, U.S. Treasury securities and corporate debt securities with maturities ranging from one year to three years that 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. (5) See Note 9 for the classification of commodity and foreign currency contracts on the Condensed Consolidated Balance Sheet. Commodity and foreign currency contracts are estimated using standard pricing models with market-based inputs, which take into account the present value of estimated future cash flows. All of the company’s financial instruments carried at fair value are included in the table above. All of the above financial instruments are available-for-sale securities except for those held in the deferred compensation trusts (which are trading securities) and derivative assets and liabilities. The company has determined that there was no other-than-temporary impairment of available-for-sale securities with unrealized losses, and the company expects to recover the entire cost basis of the securities. The available-for-sale securities are made up of the following security types as of September 30, 2017: money market funds of $7 million, U.S. agency securities of $10 million, U.S. Treasury securities of $75 million, corporate debt securities of $124 million and commercial paper of $5 million. As of December 31, 2016, available-for-sale securities consisted of money market funds of $21 million, U.S. agency securities of $11 million, U.S. Treasury securities of $87 million and corporate debt securities of $100 million. The amortized cost of these available-for-sale securities is not materially different from the fair value. During the three and nine months ended September 30, 2017, proceeds from sales and maturities of available-for-sale securities were $34 million and $78 million, respectively, compared to $38 million and $252 million for the corresponding periods of 2016. In addition to assets and liabilities that are measured at fair value on a recurring basis, the company is required to measure certain assets and liabilities at fair value on a nonrecurring basis. See Note 18 for further discussion of nonrecurring fair value measurements related to the company’s acquisition of Stork. The carrying values and estimated fair values of the company’s financial instruments that are not required to be measured at fair value in the Condensed Consolidated Balance Sheet are as follows: September 30, 2017 December 31, 2016 Fair Value Carrying Fair Carrying Fair (in thousands) Hierarchy Value Value Value Value Assets: Cash (1) Level 1 $ $ $ $ Cash equivalents (2) Level 2 Marketable securities, current (3) Level 2 Notes receivable, including noncurrent portion (4) Level 3 Liabilities: 1.750% Senior Notes (5) Level 2 $ $ $ $ 3.375% Senior Notes (5) Level 2 3.5% Senior Notes (5) Level 2 Revolving Credit Facility (6) Level 2 — — Other borrowings, including noncurrent portion (7) Level 2 (1) Cash consists of bank deposits. 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, current 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 by the company 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 1.750% Senior Notes, 3.375% Senior Notes and 3.5% Senior Notes were estimated based on quoted market prices for similar issues. (6) Amounts represent borrowings under the company’s €125 million Revolving Credit Facility which expired in April 2017, as discussed in Note 11. The carrying amount of the borrowings under this revolving credit facility approximated fair value because of the short-term maturity. (7) Other borrowings primarily represent bank loans and other financing arrangements resulting from the acquisition of Stork. See Note 18 for a further discussion of the acquisition. The majority of these borrowings mature within one year. The carrying amounts of the borrowings under these arrangements approximate fair value because of the short-term maturity.

Derivatives and Hedging

Derivatives and Hedging	9 Months Ended

Derivatives and Hedging
Derivatives and Hedging	(9) Derivatives and Hedging The company limits exposure to foreign currency fluctuations in most of its engineering and construction contracts through provisions that require client payments in currencies corresponding to 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. In cases where financial exposure is identified, the company generally implements a hedging strategy utilizing derivatives or hedging instruments to mitigate the risk. The company’s hedging instruments are designated as either fair value or cash flow hedges in accordance with ASC 815, “Derivatives and Hedging.” The company formally documents its hedge relationships at inception, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction. The company also formally assesses, both at inception and at least quarterly thereafter, whether the hedging instruments are highly effective in offsetting changes in the fair value of the hedged items. The fair values of all hedging instruments are recognized as assets or liabilities at the balance sheet date. For fair value hedges, the effective portion of the change in the fair value of the hedging instrument is offset against the change in the fair value of the underlying asset or liability through earnings. For cash flow hedges, the effective portion of the hedging instrument’s gain or loss due to changes in fair value is recorded as a component of AOCI and is reclassified into earnings when the hedged item settles. Any ineffective portion of a hedging instrument’s change in fair value is immediately recognized in earnings. 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. The company does not enter into derivative instruments for speculative purposes. Under ASC 815, 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. The company maintains master netting arrangements with certain counterparties to facilitate the settlement of derivative instruments; however, the company reports the fair value of derivative instruments on a gross basis. As of September 30, 2017, the company had total gross notional amounts of approximately $884 million of foreign currency contracts (primarily related to the British Pound, Kuwaiti Dinar, Indian Rupee, Philippine Peso and South Korean Won) and $0.4 million for a commodity contract outstanding related to hedging of engineering and construction contract obligations. The foreign currency contracts are of varying duration, none of which extend beyond December 2019. The commodity contract expires in December 2017. The impact to earnings due to hedge ineffectiveness was immaterial for the three and nine months ended September 30, 2017 and 2016. The fair values of derivatives designated as hedging instruments under ASC 815 as of September 30, 2017 and December 31, 2016 were as follows: Asset Derivatives Liability Derivatives Balance Sheet September 30, December 31, Balance Sheet September 30, December 31, (in thousands) Location 2017 2016 Location 2017 2016 Commodity contracts Other current assets $ $ Other accrued liabilities $ –– $ Foreign currency contracts Other current assets Other accrued liabilities Foreign currency contracts Other assets Noncurrent liabilities Total $ $ $ $ The pre-tax net gains (losses) recognized in earnings associated with the hedging instruments designated as fair value hedges for the three and nine months ended September 30, 2017 and 2016 were as follows: Three Months Ended Nine Months Ended Fair Value Hedges (in thousands) Location of Gain (Loss) 2017 2016 2017 2016 Foreign currency contracts Corporate general and administrative expense $ $ $ $ ) The pre-tax amount of gain (loss) recognized in earnings associated with the hedging instruments designated as fair value hedges noted in the table above offset the amount of gain (loss) recognized in earnings on the hedged items in the same locations in the Condensed Consolidated Statement of Earnings. The after-tax amount of gain (loss) recognized in OCI associated with the derivative instruments designated as cash flow hedges was as follows: Three Months Ended Nine Months Ended Cash Flow Hedges (in thousands) 2017 2016 2017 2016 Commodity contracts $ $ ) $ $ Foreign currency contracts ) ) Total $ ) $ $ $ ) The after-tax amount of gain (loss) reclassified from AOCI into earnings associated with the derivative instruments designated as cash flow hedges was as follows: Three Months Ended Nine Months Ended Cash Flow Hedges (in thousands) Location of Gain (Loss) 2017 2016 2017 2016 Commodity contracts Total cost of revenue $ $ ) $ ) $ ) Foreign currency contracts Total cost of revenue ) ) Interest rate contracts Interest expense ) ) ) ) Total $ $ ) $ $ ) As of September 30, 2017 and 2016, the company had total gross notional amounts of $106 million and $0.3 million, respectively, of foreign currency contracts outstanding that were not designated as hedging instruments. As of September 30, 2016, the company also had total gross notional amounts of $0.1 million of commodity contracts outstanding that were not designated as hedging instruments. These contracts primarily related to engineering and construction contract obligations and monetary assets and liabilities denominated in nonfunctional currencies. As of September 30, 2017, the company had total gross notional amounts of $81 million associated with contractual foreign currency payment provisions that were deemed embedded derivatives. Net gains of $0.5 million and $3.4 million associated with the company’s derivatives and embedded derivatives were included in Cost of Revenue for the three and nine months ended September 30, 2017, respectively. A loss of $0.3 million and a gain of less than $0.1 million associated with the company’s derivatives were included in Cost of Revenue for the three and nine months ended September 30, 2016, respectively.

Financing Arrangements
Financing Arrangements	(11) Financing Arrangements As of September 30, 2017, the company had both committed and uncommitted lines of credit available to be used for revolving loans and letters of credit. As of September 30, 2017, letters of credit and borrowings totaling $1.7 billion were outstanding under these committed and uncommitted lines of credit. The committed lines of credit include 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. The company may utilize up to $1.75 billion in the aggregate of the combined $3.5 billion committed lines of credit for revolving loans, which may be used for acquisitions and/or general purposes. Each of the credit facilities may be increased up to an additional $500 million subject to certain conditions, and contains customary financial and restrictive covenants, including a maximum ratio of consolidated debt to tangible net worth of one-to-one and a cap on the aggregate amount of debt of the greater of $750 million or €750 million for the company’s subsidiaries. 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. In connection with the Stork acquisition, the company assumed a €110 million Super Senior Revolving Credit Facility that bore interest at EURIBOR plus 3.75%. In April 2016, the company repaid and replaced the €110 million Super Senior Revolving Credit Facility with a €125 million Revolving Credit Facility which was used for revolving loans, bank guarantees, letters of credit and to fund working capital in the ordinary course of business. This replacement facility, which bore interest at EURIBOR plus .75%, expired in April 2017. Outstanding borrowings of $53 million under the €125 million Revolving Credit Facility were repaid in the first quarter of 2017. Letters of credit are provided in the ordinary course of business primarily to indemnify the company’s clients if the company fails to perform its obligations under its contracts. Surety bonds may be used as an alternative to letters of credit. In March 2016, the company issued €500 million of 1.750% Senior Notes (the “2016 Notes”) due March 21, 2023 and received proceeds of €497 million (or approximately $551 million), net of underwriting discounts. Interest on the 2016 Notes is payable annually on March 21 of each year, beginning on March 21, 2017. Prior to December 21, 2022, the company may redeem the 2016 Notes at a redemption price equal to 100 percent of the principal amount, plus a “make whole” premium described in the indenture. On or after December 21, 2022, the company may redeem the 2016 Notes at 100 percent of the principal amount plus accrued and unpaid interest, if any, to the date of redemption. Additionally, the company may redeem the 2016 Notes at any time upon the occurrence of certain changes in U.S. tax laws, as described in the indenture, at 100 percent of the principal amount plus accrued and unpaid interest, if any, to the date of redemption. In November 2014, the company issued $500 million of 3.5% Senior Notes (the “2014 Notes”) due December 15, 2024 and received proceeds of $491 million, net of underwriting discounts. Interest on the 2014 Notes is payable semi-annually on June 15 and December 15 of each year, and began on June 15, 2015. Prior to September 15, 2024, the company may redeem the 2014 Notes at a redemption price equal to 100 percent of the principal amount, plus a “make whole” premium described in the indenture. On or after September 15, 2024, the company may redeem the 2014 Notes at 100 percent of the principal amount plus accrued and unpaid interest, if any, to the date of redemption. In September 2011, the company issued $500 million of 3.375% Senior Notes (the “2011 Notes”) due September 15, 2021 and received proceeds of $492 million, net of underwriting discounts. Interest on the 2011 Notes is payable semi-annually on March 15 and September 15 of each year, and began on March 15, 2012. The company may, at any time, redeem the 2011 Notes at a redemption price equal to 100 percent of the principal amount, plus a “make whole” premium described in the indenture. For the 2016 Notes, the 2014 Notes and the 2011 Notes, if a change of control triggering event occurs, as defined by the terms of the respective indentures, the company will be required to offer to purchase the applicable notes at a purchase price equal to 101 percent of their principal amount, plus accrued and unpaid interest, if any, to the date of redemption. The company is generally not limited under the indentures governing the 2016 Notes, the 2014 Notes and the 2011 Notes in its ability to incur additional indebtedness provided the company is in compliance with certain restrictive covenants, including restrictions on liens and restrictions on sale and leaseback transactions. We may, from time to time, repurchase the 2016 Notes, the 2014 Notes or the 2011 Notes in the open market, in privately-negotiated transactions or otherwise in such volumes, at such prices and upon such other terms as we deem appropriate. In conjunction with the acquisition of Stork on March 1, 2016, the company assumed Stork’s outstanding debt obligations, including its 11.0% Super Senior Notes due 2017 (the ‘‘Stork Notes’’), borrowings under the €110 million Super Senior Revolving Credit Facility, and other debt obligations. On March 2, 2016, the company gave notice to all holders of the Stork Notes of the full redemption of the outstanding €273 million (or approximately $296 million) principal amount of Stork Notes plus a redemption premium of €7 million (or approximately $8 million) effective March 17, 2016. The redemption of the Stork Notes was initially funded with additional borrowings under the company’s $1.7 billion Revolving Loan and Letter of Credit Facility, which borrowings were subsequently repaid from the net proceeds of the 2016 Notes. Certain other outstanding debt obligations assumed in the Stork acquisition of €20 million (or approximately $22 million) were settled in March 2016. See Note 18 for a further discussion of the acquisition. Other borrowings of $41 million as of September 30, 2017 and $35 million as of December 31, 2016 primarily represent bank loans and other financing arrangements resulting from the acquisition of Stork, exclusive of the Stork Notes. As of September 30, 2017, the company was in compliance with all of the financial covenants related to its debt agreements.

Stock-Based Plans
Stock-Based Plans	(12) Stock-Based Plans The company’s executive and director stock-based compensation plans are described, and informational disclosures are provided, in the Notes to Consolidated Financial Statements included in the Form 10-K for the year ended December 31, 2016. In the first nine months of 2017 and 2016, restricted stock units totaling 402,783 and 553,415, respectively, were granted to executives and directors, at weighted-average grant date fair values of $52.57 per share and $43.77 per share, respectively. Restricted stock units granted to executives in 2017 and 2016 generally vest ratably over three years. Restricted stock units granted to directors in 2017 and 2016 generally vest on the first anniversary of the grant. For directors and certain executives, restricted stock units are subject to a post-vest holding period of three years. The fair value of restricted stock units represents the closing price of the company’s common stock on the date of grant discounted for the post-vest holding period, when applicable. During the first nine months of 2017 and 2016, stock options for the purchase of 1,103,817 shares at a weighted-average exercise price of $55.35 per share and 662,001 shares at a weighted-average exercise price of $46.07 per share, respectively, were awarded to executives. The exercise price of options represents the closing price of the company’s common stock on the date of grant. The options granted in 2017 and 2016 vest ratably over three years and expire ten years after the grant date. In the first nine months of 2017 and 2016, performance-based Value Driver Incentive (“VDI”) units totaling 249,204 and 296,052, respectively, were awarded to executives. These awards vest after a period of approximately three years and contain annual performance conditions for each of the three years of the vesting period. The performance targets for each year are generally established in the first quarter of that year. Under ASC 718, performance-based awards are not deemed granted for accounting purposes until the performance targets have been established. Accordingly, only one-third of the units awarded in any given year are deemed to be granted each year of the three year vesting period. During the first nine months of 2017, units totaling 83,068 and 92,094 under the 2017 and 2016 VDI plans, respectively, were granted at weighted-average grant date fair values of $53.35 per share and $51.62 per share, respectively. The grant date fair value is determined by adjusting the closing price of the company’s common stock on the date of grant for the post-vest holding period discount and for the effect of the market condition, when applicable. For awards granted under the 2017 VDI plan, the number of units will be adjusted at the end of each performance period based on achievement of certain performance targets and market conditions, as defined in the VDI award agreement. For awards granted under the 2016 VDI plan, the number of units is adjusted at the end of each performance period based only on the achievement of certain performance targets as defined in the VDI award agreement. Units granted under the 2017 and 2016 VDI plans can only be settled in company stock and are accounted for as equity awards in accordance with ASC 718.

Noncontrolling Interests
Noncontrolling Interests	(13) Noncontrolling Interests The company applies the provisions of ASC 810-10-45, which establishes accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net earnings attributable to the parent and to the noncontrolling interests, changes in a parent’s ownership interest and the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. As required by ASC 810-10-45, the company has separately disclosed on the face of the Condensed Consolidated Statement of Earnings for all periods presented the amount of net earnings attributable to the company and the amount of net earnings attributable to noncontrolling interests. For the three and nine months ended September 30, 2017, net earnings attributable to noncontrolling interests were $18 million and $53 million, respectively. For the three and nine months ended September 30, 2016, net earnings attributable to noncontrolling interests were $13 million and $46 million, respectively. Income taxes associated with earnings attributable to noncontrolling interests were immaterial in both periods presented. Distributions paid to noncontrolling interests were $24 million and $26 million for the nine months ended September 30, 2017 and 2016, respectively. Capital contributions by noncontrolling interests were $5 million and $9 million for the nine months ended September 30, 2017 and 2016, respectively.

Contingencies and Commitments
Contingencies and Commitments	(14) Contingencies and Commitments The company and certain of its 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, the company currently does not expect that the ultimate resolution of any open matters will have a material adverse effect on its consolidated financial position or results of operations. Fluor Australia Ltd., a wholly-owned subsidiary of the company (“Fluor Australia”), completed cost reimbursable engineering, procurement and construction management services for Santos Ltd. (“Santos”) on 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 of approximately AUD $1.47 billion. The company believes that the claims asserted by Santos are without merit and is vigorously defending these claims. Based upon the present status of this matter, the company does not believe it is probable that a loss will be incurred. Accordingly, the company has not recorded a charge as a result of this action. Other Matters The company has made claims arising from the performance under its contracts. The company recognizes revenue, but not profit, for certain claims (including change orders in dispute and unapproved change orders in regard to both scope and price) when it is determined that recovery of incurred costs is probable and the amounts can be reliably estimated. Under claims accounting (ASC 605-35-25), these requirements are satisfied when (a) the contract or other evidence provides a 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 the company’s 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, the company recognizes disputed back charges to suppliers or subcontractors as a reduction of cost when the same requirements have been satisfied. The company periodically evaluates its positions and the amounts recognized with respect to all its claims and back charges. As of September 30, 2017 and December 31, 2016, the company had recorded $80 million and $61 million, respectively, of claim revenue for costs incurred to date and such costs are included in contract work in progress. Additional costs, which will increase the claim revenue balance over time, are expected to be incurred in future periods. The company had also recorded disputed back charges totaling $43 million and $41 million as of September 30, 2017 and December 31, 2016, respectively. The company believes the ultimate recovery of amounts related to these claims and back charges is probable in accordance with ASC 605-35-25. From time to time, the company enters 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 the company’s 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, the company maintains reserves for estimated exposures associated with these matters.

Guarantees

Guarantees
Guarantees	(15) Guarantees In the ordinary course of business, the company enters into various agreements providing performance assurances and guarantees to clients on behalf of certain unconsolidated and consolidated partnerships, joint ventures and other jointly executed contracts. These agreements are entered into primarily to support the project execution commitments of these entities. The performance guarantees have various expiration dates ranging from mechanical completion of the project being constructed to a period extending beyond contract completion in certain circumstances. The maximum potential amount of future payments that the company could be required to make under outstanding performance guarantees, which represents the remaining cost of work to be performed by or on behalf of third parties under engineering and construction contracts, was estimated to be $15 billion as of September 30, 2017. 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 under the contract. For lump-sum or fixed-price 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, the company may have recourse to third parties, such as owners, co-venturers, subcontractors or vendors for claims. The company assessed its performance guarantee obligation as of September 30, 2017 and December 31, 2016 in accordance with ASC 460, “Guarantees,” and the carrying value of the liability was not material. Financial guarantees, made in the ordinary course of business in certain limited circumstances, are entered into with financial institutions and other credit grantors and generally obligate the company 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.

Partnerships and Joint Ventures

Partnerships and Joint Ventures	9 Months Ended

Partnerships and Joint Ventures
Partnerships and Joint Ventures	(16) Partnerships and Joint Ventures In the normal course of business, the company forms 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 percent 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” on the Condensed Consolidated Balance Sheet were $127 million and $392 million as of September 30, 2017 and December 31, 2016, respectively. The decrease in this receivable balance in 2017 resulted primarily from one Energy, Chemicals & Mining joint venture project in the United States. Notes receivable from unconsolidated partnerships and joint ventures included in “Accounts and notes receivable, net” and “Other assets” on the Condensed Consolidated Balance Sheet were $21 million and $19 million as of September 30, 2017 and December 31, 2016, respectively. For unconsolidated partnerships and joint ventures in the construction industry, the company generally recognizes its proportionate share of revenue, cost and profit in its Condensed Consolidated Statement of Earnings and uses the one-line equity method of accounting on the Condensed Consolidated Balance Sheet, which is a common application of ASC 810-10-45-14 in the construction industry. The equity method of accounting is also used for other investments in entities where the company has significant influence. The company’s investments in unconsolidated partnerships and joint ventures accounted for under these methods amounted to $711 million and $454 million as of September 30, 2017 and December 31, 2016, respectively, and were classified under “Investments” and “Other accrued liabilities” on the Condensed Consolidated Balance Sheet. In February 2016, the company made an initial cash investment of $350 million in COOEC Fluor Heavy Industries Co., Ltd. (“CFHI”), a joint venture in which the company has a 49% ownership interest and Offshore Oil Engineering Co., Ltd., a subsidiary of China National Offshore Oil Corporation, has 51% ownership interest. Through CFHI, the two companies own, operate and manage the Zhuhai Fabrication Yard in China’s Guangdong province. The company made an additional investment of $62 million in the third quarter of 2016 and has a future funding commitment of $78 million. Variable Interest Entities In accordance with ASC 810, “Consolidation,” the company assesses its partnerships and joint ventures at inception to determine if any meet the qualifications of a variable interest entity (“VIE”). The company considers 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 outlined in ASC 810, the company reassesses its initial determination of whether the partnership or joint venture is a VIE. The majority of the company’s 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. The company also performs a qualitative assessment of each VIE to determine if the company is its primary beneficiary, as required by ASC 810. The company concludes that it is the primary beneficiary and consolidates the VIE if the company has 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. The company considers 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 the company is the primary beneficiary. The company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. As required by ASC 810, management’s assessment of whether the company is the primary beneficiary of a VIE is continuously performed. The net carrying value of the unconsolidated VIEs classified under “Investments” and “Other accrued liabilities” on the Condensed Consolidated Balance Sheet was a net asset of $238 million as of September 30, 2017 and a net liability of $9 million as of December 31, 2016. Some of the company’s VIEs have debt; however, such debt is typically non-recourse in nature. The company’s maximum exposure to loss as a result of its 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, 2017 for the unconsolidated VIEs were $43 million. In some cases, the company is required to consolidate certain VIEs. As of September 30, 2017, the carrying values of the assets and liabilities associated with the operations of the consolidated VIEs were $1.0 billion and $582 million, respectively. As of December 31, 2016, the carrying values of the assets and liabilities associated with the operations of the consolidated VIEs were $959 million and $566 million, respectively. The assets of a VIE are restricted for use only for the particular VIE and are not available for general operations of the company. The company has agreements with certain VIEs to provide financial or performance assurances to clients. See Note 15 for a further discussion of such agreements. A discussion of some of the company’s more significant or unique VIEs is provided in the Notes to Consolidated Financial Statements included in the Form 10-K for the year ended December 31, 2016.

During the first quarter of 2017, the company changed the name of the Maintenance, Modification & Asset Integrity segment to Diversified Services. The company reports its operating results in the following four reportable segments: Energy, Chemicals & Mining; Industrial, Infrastructure & Power; Government; and Diversified Services. Operating information by reportable segment is as follows: Three Months Ended Nine Months Ended September 30, September 30, External Revenue (in millions) 2017 2016 2017 2016 Energy, Chemicals & Mining $ $ $ $ Industrial, Infrastructure & Power Government Diversified Services Total external revenue $ $ $ $ Intercompany revenue for the Diversified Services segment, excluded from the amounts shown above, was $144 million and $445 million for the three and nine months ended September 30, 2017, respectively, and $133 million and $373 million for the three and nine months ended September 30, 2016, respectively. Segment profit is an earnings measure that the company utilizes to evaluate and manage its business performance. Segment profit is calculated as revenue less cost of revenue and earnings attributable to noncontrolling interests excluding: corporate general and administrative expense; interest expense; interest income; domestic and foreign income taxes; and other non-operating income and expense items.

Segment profit in the Energy, Chemicals & Mining segment for the three and nine months ended September 30, 2016 was adversely affected by pre-tax charges of $241 million (or $1.10 per diluted share) and $265 million (or $1.20 per diluted share), respectively, related to forecast revisions for estimated cost increases on a petrochemical project in the United States. Industrial, Infrastructure & Power. Segment profit in the Industrial, Infrastructure & Power segment for the nine months ended September 30, 2017 was adversely affected by pre-tax charges totaling $219 million (or $0.99 per diluted share) resulting from forecast revisions for estimated cost growth at three fixed-price, gas-fired power plant projects in the southeastern United States, which were recognized in the first half of 2017. Segment profit in the Industrial, Infrastructure & Power segment for the three and nine months ended September 30, 2017 and 2016 included the operations of NuScale, which are primarily research and development activities associated with the licensing and commercialization of small modular nuclear reactor technology. NuScale expenses included in the determination of segment profit were $20 million and $53 million for the three and nine months ended September 30, 2017, respectively, and $22 million and $70 million for the three and nine months ended September 30, 2016, respectively. NuScale expenses were net of qualified reimbursable expenses of $12 million and $32 million for the three and nine month periods of 2017, respectively, and $15 million and $47 million for the three and nine months periods of 2016, respectively. A discussion of the cooperative agreement between NuScale and the U.S. Department of Energy is provided in the Notes to Consolidated Financial Statements included in the Form 10-K for the year ended December 31, 2016.

The decrease in total assets in the Energy, Chemicals & Mining segment resulted from decreased working capital in support of project execution activities. Total assets in the Industrial, Infrastructure & Power segment as of September 30, 2017 included accounts receivable related to two subcontracts with Westinghouse Electric Company LLC (“Westinghouse”) to manage the construction workforce at nuclear power plant projects in Georgia (“Plant Vogtle”) and South Carolina (“V.C. Summer”). On March 29, 2017 (“the bankruptcy petition date”), Westinghouse filed for Chapter 11 bankruptcy protection in the U.S. Bankruptcy Court, Southern District of New York. The company has filed mechanic’s liens in South Carolina against the property of the owner of the V.C. Summer project for amounts due for pre-petition services rendered to Westinghouse. On July 31, 2017, the V.C. Summer project was cancelled by the owner of the project and the company has demobilized from the site. On August 31, 2017, the owner of the Plant Vogtle project cancelled its contract with Westinghouse. The owner then entered into a bridge contract with the company to provide services until the remaining scope of work is transferred to the new contractor. Based on agreements with the owners of both projects, the company has been compensated by the owners for certain pre-petition services rendered to Westinghouse, and continues to be compensated for post-petition services. In addition to amounts due for post-petition services, total assets as of September 30, 2017 included amounts due of $66 million and $2 million for services provided to V.C. Summer and Plant Vogtle, respectively, prior to the date of the bankruptcy petition. Based on the company’s evaluation of available information, the company does not expect the close-out of these projects to have a material impact on the company’s results of operations.

Acquisition of Stork Holding B.

Acquisition of Stork Holding B.V.	9 Months Ended

Acquisition of Stork Holding B.V.
Acquisition of Stork Holding B.V.	(18) Acquisition of Stork Holding B.V. On March 1, 2016 (“the acquisition date”), the company acquired 100 percent of Stork for an aggregate purchase price of €695 million (or approximately $756 million), including the assumption of debt and other liabilities. Stork, based in the Netherlands, is a global provider of maintenance, modification and asset integrity services associated with large existing industrial facilities in the oil and gas, chemicals, petrochemicals, industrial and power markets. The company paid €276 million (or approximately $300 million) in cash consideration. The company borrowed €200 million (or approximately $217 million) under its $1.7 billion Revolving Loan and Letter of Credit Facility, and paid €76 million (or approximately $83 million) of cash on hand to initially finance the Stork acquisition. The €200 million borrowed under the $1.7 billion Revolving Loan and Letter of Credit Facility was subsequently repaid from the net proceeds of the 2016 Notes as discussed in Note 11. In conjunction with the acquisition, the company assumed Stork’s outstanding debt obligations, including the Stork Notes, borrowings under a €110 million Super Senior Revolving Credit Facility, and other debt obligations. On March 2, 2016, the company gave notice to all holders of the Stork Notes of the full redemption of the outstanding €273 million (or approximately $296 million) principal amount of Stork Notes plus a redemption premium of €7 million (or approximately $8 million) effective March 17, 2016. The redemption of the Stork Notes was initially funded with additional borrowings under the company’s $1.7 billion Revolving Loan and Letter of Credit Facility, which borrowings were subsequently repaid from the net proceeds of the 2016 Notes. Certain other outstanding debt obligations assumed in the Stork acquisition of €20 million (or approximately $22 million) were settled in March 2016. In April 2016, the company repaid and replaced the €110 million Super Senior Revolving Credit Facility with a €125 million Revolving Credit Facility that was available to fund working capital in the ordinary course of business. This replacement facility, which bore interest at EURIBOR plus .75%, expired in April 2017. Outstanding borrowings of $53 million under the €125 million Revolving Credit Facility were repaid in the first quarter of 2017. The company completed its valuation of Stork’s assets and liabilities at the end of 2016. The aggregate purchase price noted above was allocated to the major categories of assets acquired and liabilities assumed based upon their estimated fair values as of the acquisition date. The excess of the purchase price over the estimated fair value of the net tangible and identifiable intangible assets acquired, totaling €384 million (or approximately $417 million), was recorded as goodwill. The fair value of acquired intangible assets, which consisted primarily of customer relationships and trade names, as well as below market contracts and leases were determined using income-based approaches that utilized unobservable Level 3 inputs, including significant management assumptions such as forecasted revenue and operating margins, customer attrition, and weighted average cost of capital. Customer relationships are being amortized on a straight-line basis over their estimated useful lives of 8 years. Acquired trade names with finite lives are being amortized on a straight-line basis over their estimated useful lives, ranging from 2 to 15 years. Trade names with indefinite lives are not amortized, but are subject to annual impairment testing. The fair value of property, plant and equipment was determined using a cost-based approach that considers the estimated reproductive cost of the assets adjusted for depreciation factors, which include physical deterioration and functional or economic obsolescence. This approach uses Level 3 inputs that are generally unobservable in the marketplace. A market-based approach was also applied as a secondary method to estimate the fair value of certain assets. The market-based approach utilized observable Level 2 inputs for similar assets in active markets. Goodwill represents the excess of the purchase price over the fair value of the underlying net assets acquired. Factors contributing to the goodwill balance include the acquired established workforce and the estimated future synergies associated with the combined operations. Of the total goodwill recorded in conjunction with the Stork acquisition, none is expected to be deductible for tax purposes. The goodwill recognized in conjunction with the Stork acquisition has been reported in the Diversified Services segment. The following table summarizes the fair values of assets acquired and liabilities assumed as of the acquisition date: (in thousands) In EUR In USD Cash and cash equivalents € $ Accounts and notes receivable Contract work in progress Other current assets Property, plant and equipment Investments Intangible assets Goodwill Deferred taxes, net Other assets Trade accounts payable ) ) Advance billings on contracts ) ) Other accrued liabilities ) ) Revolving credit facility and other borrowings ) ) Long-term debt ) ) Noncurrent liabilities ) ) Noncontrolling interests ) ) Net assets acquired € $ Since the acquisition date, revenue and earnings from Stork of $350 million and $2 million for the three months ended September 30, 2016, respectively, and $863 million and $9 million for the nine months ended September 30, 2016, respectively, were included in the Condensed Consolidated Statement of Earnings. Integration costs of $1 million and $12 million for the three and nine months ended September 30, 2016, respectively, and transaction costs of $11 million for the nine months ended September 30, 2016, respectively, were included in corporate general and administrative expense. No transactions costs were recorded during the three months ended September 30, 2016.

The fair value of the money market funds represents the net asset value of the shares of such funds as of the close of business at the end of the period. The fair value of the investments in U.S. agency securities is based on pricing models, which are determined from a compilation of primarily observable market information, broker quotes in non-active markets or similar assets. (2) Consists of investments in U.S. agency securities, U.S. Treasury securities, corporate debt securities and commercial paper with maturities of less than one year that 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. (3) Consists of a registered money market fund, a short-term bond fund and an equity index fund valued at fair value. These investments, which are trading securities, represent the net asset value of the shares of such funds as 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. (4) Consists of investments in U.S. agency securities, U.S. Treasury securities and corporate debt securities with maturities ranging from one year to three years that 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. (5) See Note 9 for the classification of commodity and foreign currency contracts on the Condensed Consolidated Balance Sheet. Commodity and foreign currency contracts are estimated using standard pricing models with market-based inputs, which take into account the present value of estimated future cash flows.

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, current 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 by the company 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 1.750% Senior Notes, 3.375% Senior Notes and 3.5% Senior Notes were estimated based on quoted market prices for similar issues. (6) Amounts represent borrowings under the company’s €125 million Revolving Credit Facility which expired in April 2017, as discussed in Note 11. The carrying amount of the borrowings under this revolving credit facility approximated fair value because of the short-term maturity. (7) Other borrowings primarily represent bank loans and other financing arrangements resulting from the acquisition of Stork. See Note 18 for a further discussion of the acquisition. The majority of these borrowings mature within one year. The carrying amounts of the borrowings under these arrangements approximate fair value because of the short-term maturity.
