Principles of Consolidation	9 Months Ended
Principles of Consolidation	Sep. 30, 2016
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, 2015 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, 2016 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, 2016 and December 31, 2015 and its consolidated results of operations and cash flows for the interim periods presented. All significant intercompany transactions of consolidated subsidiaries are eliminated. Certain amounts in 2015 have been reclassified to conform to the 2016 presentation due to the implementation of new accounting pronouncements discussed below. Segment operating information for 2015 has been recast to reflect changes in the composition of the company’s reportable segments as discussed in Note 16. 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 as of and for the three and nine months ended September 30, 2016 include the financial statements of Stork Holding B.V. (“Stork”) since March 1, 2016, the date of acquisition. See Note 17 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, 2016 or requiring implementation in future periods are discussed below or in the related notes, where appropriate. In the first quarter of 2016, the company adopted Accounting Standards Update (“ASU”) 2015-17, “Balance Sheet Classification of Deferred Taxes” on a retrospective basis. This ASU requires entities to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent. As a result of the adoption of ASU 2015-17, deferred tax assets of $173 million were reclassified from current assets to noncurrent assets on the Condensed Consolidated Balance Sheet as of December 31, 2015. The adoption of ASU 2015-17 did not have any impact on the company’s results of operations or cash flows. In the first quarter of 2016, the company adopted ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments.” This ASU requires an acquirer in a business combination to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The adoption of ASU 2015-16 did not have any impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2016, the company adopted ASU 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements — Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update),” which clarifies the presentation and measurement of debt issuance costs incurred in connection with line of credit arrangements. The adoption of ASU 2015-15 did not have any impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2016, the company adopted ASU 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement” on a prospective basis. This ASU clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. The adoption of ASU 2015-05 did not have a material impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2016, the company adopted ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs” on a retrospective basis. This ASU changes the presentation of debt issuance costs on the balance sheet by requiring entities to present such costs as a direct deduction from the related debt liability rather than as an asset. As a result of the adoption of ASU 2015-03, debt issuance costs of $6 million were reclassified from noncurrent assets to a direct deduction of long-term debt on the Condensed Consolidated Balance Sheet as of December 31, 2015. The adoption of ASU 2015-03 did not have any impact on the company’s results of operations or cash flows. In the first quarter of 2016, the company adopted ASU 2015-02, “Amendments to the Consolidation Analysis.” This ASU amends the consolidation guidance for VIEs and general partners’ investments in limited partnerships and modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities. The adoption of ASU 2015-02 did not have a material impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2016, the company adopted ASU 2015-01, “Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” Under this ASU, an entity will no longer be allowed to separately disclose extraordinary items, net of tax, in the income statement after income from continuing operations if an event or transaction is unusual in nature and occurs infrequently. The adoption of ASU 2015-01 did not have any impact on the company’s financial position, results of operations or cash flows. In the first quarter of 2016, the company adopted ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved After the Requisite Service Period.” This ASU requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. The adoption of ASU 2014-12 did not have any impact on the company’s financial position, results of operations or cash flows. In August 2016, the Financial Accounting Standards Board (“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 2016-13 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 March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” This ASU is intended to simplify various aspects of the 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. ASU 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Management is currently evaluating the impact of adopting ASU 2016-09 on the company’s financial position, results of operations and cash flows. In March 2016, the FASB issued 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. ASU 2016-07 is effective for interim and annual reporting periods beginning after December 15, 2016, and should be applied prospectively. Management does not expect the adoption of ASU 2016-07 to have a material impact on the company’s financial position, results of operations or cash flows. In March 2016, the FASB issued 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. ASU 2016-05 is effective for interim and annual reporting periods beginning after December 15, 2016. ASU 2016-05 can be applied on either a prospective or modified retrospective basis. Management does not expect the adoption of ASU 2016-05 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. In August 2014, the FASB issued ASU 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This ASU requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and to provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. ASU 2014-15 is effective for annual reporting periods ending after December 15, 2016 and subsequent interim reporting periods. Management does not expect the adoption of ASU 2014-15 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 require separate accounting (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. Early adoption is permitted as of interim and annual reporting periods beginning after December 15, 2016. 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. ASU 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 and 2016-12 on the company’s financial position, results of operations, cash flows and related disclosures. 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.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2016
Income Taxes
Income Taxes	(4)Income Taxes The effective tax rates on earnings from continuing operations for the three and nine months ended September 30, 2016 were impacted by a benefit for a favorable resolution of an IRS audit for tax years 2009-2013 and an increase in the research tax credit. Both the 2015 and 2016 periods benefitted from earnings attributable to noncontrolling interests for which income taxes are not typically the responsibility of the company. The company’s effective tax rate on the loss from discontinued operations for the three and nine months ended September 30, 2015 was 35.5 percent. 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 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 2012.

Fair Value Measurements

Fair Value Measurements

(7) 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, 2016 and December 31, 2015:

(2)

Consists of investments in U.S. agency securities, U.S. Treasury securities and corporate debt securities 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 primarily of registered money market funds 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 8 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, 2016: money market funds of $18 million, U.S. agency securities of $12 million, U.S. Treasury securities of $87 million and corporate debt securities of $103 million. As of December 31, 2015, available-for-sale securities consisted of money market funds of $19 million, U.S. agency securities of $18 million, U.S. Treasury securities of $102 million and corporate debt securities of $189 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, 2016, proceeds from sales and maturities of available-for-sale securities were $38 million and $252 million, respectively, compared to $94 million and $296 million for the corresponding periods of 2015.

The carrying values and estimated fair values of the company’s financial instruments that are not required to be measured at fair value on the Condensed Consolidated Balance Sheet are as follows:

(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 expires in April 2017, as discussed in Note 10. The carrying amount of the borrowings under this revolving credit facility approximates fair value because of the short-term maturity.

(7)

Other borrowings as of September 30, 2016 primarily represent bank loans and other financing arrangements assumed in conjunction with the acquisition of Stork. See Note 17 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

Derivatives and Hedging

(8) 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 derivative instruments as hedging instruments to mitigate the risk. These 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. The company does not enter into derivative instruments for speculative purposes. 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, 2016, the company had total gross notional amounts of $817 million of foreign currency contracts and $5 million of commodity contracts outstanding relating to hedging of engineering and construction contract obligations and monetary assets and liabilities denominated in nonfunctional currencies. The foreign currency contracts are of varying duration, none of which extend beyond December 2019. The commodity contracts are of varying duration, none of which extend beyond December 2017. The impact to earnings due to hedge ineffectiveness was immaterial for the three and nine months ended September 30, 2016 and 2015.

The fair values of derivatives designated as hedging instruments under ASC 815 as of September 30, 2016 and December 31, 2015 were as follows:

	Asset Derivatives					Liability Derivatives
	Balance Sheet	September 30,		December 31,		Balance Sheet	September 30,		December 31,

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, 2016 and 2015 were as follows:

		Three Months Ended					Nine Months Ended

Foreign currency contracts	Corporate general and administrative expense	$	629	$	(7,641	)	$	(697	)	$	(3,558	)

The pre-tax amount of gain (loss) recognized in earnings on hedging instruments for the 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 on 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
	September 30,						September 30,
Cash Flow Hedges (in thousands)	2016			2015			2016			2015

Total		$	(637	)	$	(918	)	$	(3,455	)	$	(1,597	)

As of September 30, 2016, the company also had total gross notional amounts of $0.3 million of foreign currency contracts and $0.1 million of commodity contracts outstanding that were not designated as hedging instruments. These contracts primarily related to engineering and construction and operations and maintenance contract obligations denominated in nonfunctional currencies. A loss of $0.3 million and a gain of less than $0.1 million associated with these contracts were included in Cost of Revenues for the three and nine months ended September 30, 2016, respectively.

In December 2015, the company settled the remaining obligations associated with its U.S. defined benefit pension plan. A detailed discussion of the plan settlement is provided in the Notes to Consolidated Financial Statements included in the Form 10-K for the year ended December 31, 2015.

The company currently expects to contribute between $15 million and $20 million into its non-U.S. defined benefit pension plans during 2016, which is expected to be in excess of the minimum funding required. During the nine months ended September 30, 2016, contributions of approximately $15 million were made by the company.

During the nine months ended September 30, 2015, lump-sum distributions to participants of the U.S. Plan exceeded the sum of the service cost and interest cost components of net periodic pension cost. As a result, the company recorded a pre-tax settlement charge of $9 million during the third quarter of 2015 which was included in “Corporate general and administrative expense” in the Condensed Consolidated Statement of Earnings. The lump-sum distributions were funded by assets of the U.S. Plan.

In anticipation of the plan settlement, the company purchased $10 million in investments in limited partnerships from the U.S. Plan during the third quarter of 2015, as allowed under a prohibited transaction exemption with the U.S. Department of Labor. The purchase price approximated the fair value of the investments as of September 30, 2015. The company’s investments in the limited partnerships are accounted for as cost method investments.

Financing Arrangements	(10) Financing Arrangements As of September 30, 2016, the company had a combination of committed and uncommitted lines of credit totaling $6.0 billion that may be used for revolving loans and letters of credit. As of September 30, 2016, letters of credit and borrowings totaling $1.9 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 2021. 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 may be used for revolving loans, bank guarantees, letters of credit and to fund working capital in the ordinary course of business. This replacement facility expires in April 2017 and bears interest at EURIBOR plus .75%. The €125 million Revolving Credit Facility was included in committed lines of credit as of September 30, 2016. Outstanding borrowings under this facility amounted to €80 million (or approximately $90 million) as of September 30, 2016. 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, 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. 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 17 for a further discussion of the acquisition. Other borrowings of $54 million as of September 30, 2016 primarily represent bank loans and other financing arrangements assumed in conjunction with the acquisition of Stork, exclusive of the Stork Notes. As of September 30, 2016, the company was in compliance with all of the financial covenants related to its debt agreements.

Noncontrolling Interests	9 Months Ended
Noncontrolling Interests	Sep. 30, 2016
Noncontrolling Interests
Noncontrolling Interests	(12) 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, 2016, net earnings attributable to noncontrolling interests were $13 million and $46 million, respectively. For the three and nine months ended September 30, 2015, net earnings attributable to noncontrolling interests were $10 million and $44 million, respectively. Income taxes associated with earnings attributable to noncontrolling interests were immaterial in both periods presented. Distributions paid to noncontrolling interests were $26 million and $45 million for the nine months ended September 30, 2016 and 2015, respectively. Capital contributions by noncontrolling interests were $9 million and $4 million for the nine months ended September 30, 2016 and 2015, respectively.

Contingencies and Commitments	9 Months Ended
Contingencies and Commitments	Sep. 30, 2016
Contingencies and Commitments
Contingencies and Commitments	(13) 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. 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 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. The company periodically evaluates its position and the amounts recognized in revenue with respect to all its claims. As of September 30, 2016 and December 31, 2015, the company had recorded $56 million and $30 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 quarters. The company believes the ultimate recovery of incurred and future costs related to these claims 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	9 Months Ended
Guarantees	Sep. 30, 2016
Guarantees
Guarantees	(14) 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 $17.3 billion as of September 30, 2016. 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, 2016 and December 31, 2015 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	9 Months Ended
Partnerships and Joint Ventures	Sep. 30, 2016
Partnerships and Joint Ventures
Partnerships and Joint Ventures	(15) 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. Receivables related to work performed for unconsolidated partnerships and joint ventures included in “Accounts and notes receivable, net” on the Condensed Consolidated Balance Sheet were $181 million and $132 million as of September 30, 2016 and December 31, 2015, 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 $487 million and $292 million as of September 30, 2016 and December 31, 2015, 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. An additional investment of $62 million was made in the third quarter of 2016 and another $78 million is expected to be made in September 2017. 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 either (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 $21 million and $208 million as of September 30, 2016 and December 31, 2015, respectively. 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 commitments. Future funding commitments as of September 30, 2016 for the unconsolidated VIEs were $36 million. In some cases, the company is required to consolidate certain VIEs. As of September 30, 2016, the carrying values of the assets and liabilities associated with the operations of the consolidated VIEs were $1.1 billion and $570 million, respectively. As of December 31, 2015, the carrying values of the assets and liabilities associated with the operations of the consolidated VIEs were $863 million and $443 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 14 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, 2015.

Operating Information by Segment

Operating Information by Segment

(16) Operating Information by Segment

During the first quarter of 2016, the company changed the composition of its reportable segments to better reflect the diverse end markets that the company serves. The company now reports its operating results in four reportable segments as follows: Energy, Chemicals & Mining; Industrial, Infrastructure & Power; Government; and Maintenance, Modification & Asset Integrity. Segment operating information and assets for 2015 have been recast to reflect these changes.

The Energy, Chemicals & Mining segment is driven by the supply and demand for commodities. This segment provides design, engineering, procurement, construction, fabrication and project management services for chemicals and petrochemicals, downstream refining, pipelines, upstream oil and gas production, liquefied natural gas and offshore production markets. This segment also provides design, engineering, procurement, construction, project management and commissioning and start-up support for mining and metals markets.

The Industrial, Infrastructure & Power segment provides design, engineering, procurement, construction, project management, start-up and commissioning, and technical services to the transportation, commercial and institutional, life sciences and advanced manufacturing, telecommunications, microelectronics and water sectors as well as the gas fueled, solid fueled, environmental compliance, renewables, and nuclear power markets. The Industrial, Infrastructure & Power segment includes the operations of NuScale Power, LLC, an Oregon-based designer of small modular nuclear reactors, which is managed as a separate operating segment within the Industrial, Infrastructure & Power segment.

The Government segment provides engineering, construction, logistics, base and facilities operations and maintenance, contingency response and environmental and nuclear services to the U.S. government and governments abroad.

The Maintenance, Modification & Asset Integrity segment is comprised of several operating segments that do not meet the requirements under ASC 280, “Segment Reporting” for separate disclosure, and therefore, have been combined under the aggregation criteria of ASC 280. The Maintenance, Modification & Asset Integrity segment includes the operations of the company’s equipment business, temporary staffing, power services, the former operations and maintenance business line as well as Stork.

For service contracts (including maintenance contracts) that do not satisfy the criteria for revenue recognition using the percentage-of-completion method, revenue is recognized when services are performed. Revenue recognized on service contracts that have not been billed to clients is classified as a current asset under contract work in progress. Amounts billed to clients in excess of revenue recognized on service contracts to date are classified as a current liability under advance billings on contracts.

Operating information by reportable segment is as follows:

	Three Months Ended				Nine Months Ended

Intercompany revenue for the Maintenance, Modification & Asset Integrity segment, excluded from the amounts shown above, was $133 million and $373 million for the three and nine months ended September 30, 2016, respectively, and $107 million and $331 million for the three and nine months ended September 30, 2015, 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; other non-operating income and expense items; and loss from discontinued operations.

Total segment profit	$	24.6		$	240.3		$	495.7	$	798.0

Energy, Chemicals & Mining. Segment profit 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 for the three and nine months ended September 30, 2016 and 2015 included the operations of NuScale, which are primarily research and development activities associated with the licensing and commercialization of small modular nuclear reactor technology. In May 2014, NuScale entered into a cost-sharing agreement with the U.S. Department of Energy (“DOE”) establishing the terms and conditions of a multi-year funding award that allows certain qualified expenditures to be reimbursed. NuScale expenses included in the determination of segment profit were $22 million and $70 million for the three and nine months ended September 30, 2016, respectively, and $29 million and $65 million for the three and nine months ended September 30, 2015, respectively. NuScale expenses were net of qualified reimbursable expenses of $15 million and $47 million for the three and nine month periods of 2016, respectively, and $13 million and $44 million for the three and nine month periods of 2015, respectively. The company recognizes the cost-sharing award with the DOE, when earned, as a reduction of “Total cost of revenue” on the Condensed Consolidated Statement of Earnings and, correspondingly, as an increase to segment profit in the period for which the related costs are recognized.

A reconciliation of total segment profit to net earnings attributable to Fluor Corporation is as follows:

Energy, Chemicals & Mining	$	2,376.9	$	1,728.0
Industrial, Infrastructure & Power	763.8		544.2
Government	504.3		495.4
Maintenance, Modification & Asset Integrity	2,058.9		923.8

The increase in total assets in the Energy, Chemicals & Mining segment resulted from the company’s investment in CFHI and increased working capital in support of project execution activities. The increase in total assets in the Industrial, Infrastructure & Power segment resulted from increased working capital in support of project execution activities. The increase in total assets in the Maintenance, Modification & Asset Integrity resulted from the company’s acquisition of Stork.

Acquisition of Stork Holding B.V.

9 Months Ended

Sep. 30, 2016

Acquisition of Stork Holding B.V.

Acquisition of Stork Holding B.V.

(17) Acquisition of Stork Holding B.V.

In December 2015, the company signed an agreement to acquire 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.

On March 1, 2016 (“the acquisition date”), the company completed the Stork acquisition and 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 10.

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 is available to fund working capital in the ordinary course of business. This replacement facility expires in April 2017 and bears interest at EURIBOR plus .75%.

The purchase accounting for assets acquired and liabilities assumed in connection with the Stork acquisition is incomplete as of the filing date of this Form 10-Q. Third party valuations for property, plant and equipment, intangible assets and liabilities, and pension obligations are still underway; and the company is continuing to assess deferred taxes, certain tax positions and other liabilities related to the acquisition. Therefore, the amounts recognized in the financial statements for the business combination have been determined provisionally. The aggregate purchase price noted above has been preliminarily 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 €429 million (or approximately $466 million), has been preliminarily recorded as goodwill.

The company has made certain changes to the preliminary purchase price allocation since the initial estimates reported in the first quarter of 2016. These changes primarily relate to the following:

Identifiable intangible assets, which were originally aggregated with goodwill, have been separately reported at their estimated fair value of €167 million (or approximately $181 million).

Deferred tax liabilities increased by €47 million (or approximately $51 million) primarily to record the deferred tax impact of valuation adjustments associated with identifiable intangible assets.

Property, plant and equipment increased by €8 million (or approximately $9 million) to reflect its estimated fair value.

Additional fair value adjustments, primarily related to contracts, and certain balance sheet reclassifications have been made to other assets and liabilities resulting in a net decrease of €25 million (or approximately $27 million) to net assets acquired. These adjustments did not materially affect any individual asset or liability account.

Goodwill decreased by €103 million (or approximately $112 million) to reflect all of the changes to the purchase price allocation noted above.

Adjustments to the Condensed Consolidated Statement of Earnings for the three and nine months ended September 30, 2016 related to the income effects that would have been recognized in previous periods if the adjustments to provisional amounts were recognized as of the acquisition date were not significant.

The purchase price allocation is based upon preliminary information and is subject to change when additional information is obtained. The following table summarizes the company’s updated preliminary estimate of the fair values of assets acquired and liabilities assumed as of the acquisition date:

(in thousands)	In EUR			In USD

Cash and cash equivalents	€	54,441		$	59,204

Net assets acquired	€	275,813		$	299,944

(1)

Acquired intangible assets consist primarily of customer relationships and trade names. A third party valuation is currently underway to determine the fair value of identifiable intangible assets and their useful lives.

(2)

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 Maintenance, Modification & Asset Integrity segment.

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, have been included on 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 were included in corporate general and administrative expense. No transactions costs were recorded during the three months ended September 30, 2016.

The following pro forma financial information reflects the Stork acquisition as if it had occurred on January 1, 2015 and includes adjustments for debt refinancing and transaction costs.

	Three Months Ended September 30,				Nine Months Ended September 30,

Partial Sale of a Subsidiary	9 Months Ended
Partial Sale of a Subsidiary	Sep. 30, 2016
Partial Sale of a Subsidiary
Partial Sale of a Subsidiary	(18) Partial Sale of a Subsidiary On September 30, 2015, the company sold 50% of its ownership of Fluor S.A., its principal Spanish operating subsidiary, to Sacyr Industrial, S.L.U. for a cash purchase price of approximately $46 million, subject to certain purchase price adjustments. The company deconsolidated the subsidiary and recorded a pre-tax non-operating gain of $68 million during the third quarter of 2015, which was determined based on the sum of the proceeds received on the sale and the estimated fair value of the company’s retained 50% noncontrolling interest, less the carrying value of the net assets associated with the former subsidiary. The estimated fair value of the company’s retained noncontrolling interest was $44 million as of the transaction date. The fair value was estimated using a combination of income-based and market-based valuation approaches utilizing unobservable Level 3 inputs, including significant management assumptions such as forecasted revenue and operating margins, weighted average cost of capital and earnings multiples. Observable inputs, such as the cash consideration received for the divested share of the entity, were also considered.

Discontinued Operations	9 Months Ended
Discontinued Operations	Sep. 30, 2016
Discontinued Operations
Discontinued Operations	(19) Discontinued Operations During the nine months ended September 30, 2015, the company made payments totaling $306 million to settle certain lead exposure cases associated with the divested lead business of St. Joe Minerals Corporation and The Doe Run Company in Herculaneum, Missouri, which the company sold in 1994. The company has filed suit against the buyer seeking indemnification for all liabilities arising from these lead exposure cases. During the three and nine months ended September 30, 2015, the company recorded an after-tax loss from discontinued operations of $5 million resulting from the settlement of lead exposure cases related to the divested lead business and the payment of legal fees incurred in connection with a pending indemnification action against the buyer of the lead business for these settlements and others. The tax effects associated with these losses were $3 million for both the three and nine months ended September 30, 2015.

- Definition

The entire disclosure related to a disposal group. Includes, but is not limited to, a discontinued operation, disposal classified as held-for-sale or disposed of by means other than sale or disposal of an individually significant component.
