Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

1. BASIS OF PRESENTATION

Curtiss-Wright Corporation and its subsidiaries (the "Corporation" or the "Company") is a global, diversified manufacturing and service company that designs, manufactures, and overhauls precision components and provides highly engineered products and services to the aerospace, defense, power generation, and general industrial markets.

The unaudited condensed consolidated financial statements include the accounts of Curtiss-Wright and its majority-owned subsidiaries. All intercompany transactions and accounts have been eliminated.

The unaudited condensed consolidated financial statements of the Corporation have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted as permitted by such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of these financial statements.

Management is required to make estimates and judgments that affect the reported amount of assets, liabilities, revenue, and expenses and disclosure of contingent assets and liabilities in the accompanying financial statements. Actual results may differ from these estimates. The most significant of these estimates includes the estimate of costs to complete long-term contracts under the percentage-of-completion accounting methods, the estimate of useful lives for property, plant, and equipment, cash flow estimates used for testing the recoverability of assets, pension plan and postretirement obligation assumptions, estimates for inventory obsolescence, estimates for the valuation and useful lives of intangible assets, legal reserves, and the estimate of future environmental costs. Changes in estimates of contract sales, costs, and profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current and prior periods. Accordingly, the effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate. In the three month periods ended March 31, 2018 and 2017, there were no individual significant changes in estimated contract costs. In the opinion of management, all adjustments considered necessary for a fair presentation have been reflected in these financial statements.

The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Corporation’s 2017 Annual Report on Form 10-K. The results of operations for interim periods are not necessarily indicative of trends or of the operating results for a full year.

Recent accounting pronouncements adopted

ASU 2014-09 - Revenue from Contracts with Customers - On January 1, 2018, the Corporation adopted ASC 606, Revenue from Contracts with Customers, and the related amendments (“new revenue standard”) using the modified retrospective method. The Corporation recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the retained earnings balance as of January 1, 2018. Comparative information for prior periods has not been restated and continues to be reported under the accounting standard in effect for those respective periods.

The cumulative effect from the adoption of the new revenue standard as of January 1, 2018 was as follows:



Balance Sheet (In thousands)	As of December 31, 2017		Adjustments due to ASU 2014-09			As of January 1, 2018
Receivables, net	$	494,923	$	18,363		$	513,286

Retained earnings	1,944,324		(2,274		)	1,942,050

ASU 2017-07, Retirement Benefits - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost - On January 1, 2018, the Corporation adopted the amendments to ASC 715 that improve the presentation of net periodic pension and postretirement benefit costs. The Corporation retrospectively adopted the presentation of service cost separate from the other components of net periodic costs and included it as a component of employee compensation cost in operating income. The interest cost, expected return on assets, amortization of prior service costs, and net actuarial gain/loss components of net periodic benefit costs have been reclassified from operating income to other income, net. Additionally, the Corporation elected to apply the practical expedient which allows it to reclassify amounts disclosed previously in Note 15 of the Corporation's 2017 Annual Report on Form 10-K as the basis for applying retrospective presentation for comparative periods.

The effect of the retrospective change on the Corporation's Condensed Consolidated Statement of Earnings for the three months ended March 31, 2017, was as follows:



	Three Months Ended March 31, 2017
Statement of Earnings (In thousands)	Previously Reported		Adjustments Increase/(Decrease)			As Revised

ASU 2017-01, Business Combinations - Clarifying the Definition of a Business. On January 1, 2018, the Corporation adopted the amendments to ASC 805 which clarifies the definition of a business. The standard introduces a screen for determining when assets acquired are not a business and clarifies that a business must include, at a minimum, an input and a substantive process that contribute to an output. The adoption of this standard did not have a financial impact on the Condensed Consolidated Financial Statements.

Recent accounting pronouncements to be adopted



Standard	Description	Effect on the condensed consolidated financial statements
ASU 2016-02 Leases	In February 2016, the FASB issued final guidance that will require lessees to put most leases on their balance sheets but recognize expenses on their income statements in a manner similar to today’s accounting.	The Corporation is currently evaluating the impact of the adoption of this standard on its Condensed Consolidated Financial Statements.
Date of adoption: January 1, 2019
ASU 2018-02 Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income	In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU permits the reclassification of tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the 2017 Tax Cuts and Jobs Act (the Tax Act). The standard will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted.	The Corporation is currently evaluating the impact of the adoption of this standard on its Condensed Consolidated Financial Statements.
Date of adoption: January 1, 2019

Impact from the Tax Act

In accordance with Staff Bulletin No. 118, Income Tax Implications of the Tax Cuts and Jobs Act, the Corporation recognized the income tax effects of the Tax Act in its consolidated financial statements for the year ended December 31, 2017. During the three months ended March 31, 2018, the Corporation recorded additional provisional tax expense of $6.5 million for foreign withholding taxes associated with the Tax Act. The Corporation expects to finalize any provisional amounts associated with the Tax Act over the next nine months based on ongoing assessment of its tax positions and other relevant data.

REVENUE (Notes)

Revenue Recognition [Abstract]

Revenue from Contract with Customer [Text Block]

2. REVENUE

As discussed in Note 1, the Corporation accounts for revenues in accordance with ASC 606, Revenue from Contracts with Customers, which was adopted as January 1, 2018 on a modified retrospective basis. Under ASC 606, revenue is recognized when control of a promised good and/or service is transferred to a customer in an amount that reflects the consideration that the Corporation expects to be entitled to in exchange for that good and/or service.

Performance Obligations

The Corporation identifies a performance obligation for each promise in a contract to transfer a distinct good or service to the customer. As part of its assessment, the Corporation considers all goods and/or services promised in the contract, regardless of whether they are explicitly stated or implied by customary business practices. The Corporation’s contracts may contain either a single performance obligation, including the promise to transfer individual goods or services that are not separately distinct within the context of the respective contracts, or multiple performance obligations. For contracts with multiple performance obligations, the Corporation allocates the overall transaction price to each performance obligation using standalone selling prices, where available, or utilizes estimates for each distinct good or service in the contract where standalone prices are not available.

The Corporation’s performance obligations are satisfied either at a point-in-time or on an over-time basis. Revenue recognized on an over-time basis accounted for approximately 31% of total net sales for the three months ended March 31, 2018. Typically, over-time revenue recognition is based on the utilization of an input measure used to measure progress, such as costs incurred to date relative to total estimated costs. Revenue recognized at a point-in-time accounted for approximately 69% of total net sales for the three months ended March 31, 2018. Revenue for these types of arrangements is recognized at the point in time in which control is transferred to the customer, typically based upon the terms of delivery.

Contract backlog represents the remaining performance obligations that have not yet been recognized as revenue. Backlog includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. Total backlog was approximately $2.1 billion as of March 31, 2018, of which the Corporation expects to recognize approximately 88% as net sales over the next 12 -36 months. The remainder will be recognized thereafter.

Disaggregation of Revenue

The following table presents the Corporation’s total net sales disaggregated by end market and customer type:

Total Commercial Customers	$	342,207	$	340,550

Total	$	547,522	$	523,591

Contract Balances

Timing of revenue recognition and cash collection may result in billed receivables, unbilled receivables (contract assets), and deferred revenue (contract liabilities) on the Condensed Consolidated Balance Sheet. The Corporation’s contract assets primarily relate to its rights to consideration for work completed but not billed as of the reporting date. Contract assets are transferred to billed receivables when the rights to consideration become unconditional. This is typical in situations where amounts are billed as work progresses in accordance with agreed-upon contractual terms or upon achievement of contractual milestones. The Corporation’s contract liabilities primarily consist of customer advances received prior to revenue being earned. Revenue recognized during the three months ended March 31, 2018 included in the contract liabilities balance at the beginning of the year was approximately $36 million. Changes in contract assets and contract liabilities as of March 31, 2018, were not materially impacted by any other factors. Contract assets and contract liabilities are reported in the "Receivables, net" and "Deferred revenue" lines, respectively, within the Condensed Consolidated Balance Sheet.

ACQUISITIONS

3. ACQUISITIONS

The Corporation continually evaluates potential acquisitions that either strategically fit within the Corporation’s existing portfolio or expand the Corporation’s portfolio into new product lines or adjacent markets. The Corporation has completed a number of acquisitions that have been accounted for as business combinations and have resulted in the recognition of goodwill in the Corporation's financial statements. This goodwill arises because the purchase prices for these businesses reflect the future earnings and cash flow potential in excess of the earnings and cash flows attributable to the current product and customer set at the time of acquisition. Thus, goodwill inherently includes the know-how of the assembled workforce, the ability of the workforce to further improve the technology and product offerings, and the expected cash flows resulting from these efforts. Goodwill may also include expected synergies resulting from the complementary strategic fit these businesses bring to existing operations.

The Corporation allocates the purchase price at the date of acquisition based upon its understanding of the fair value of the acquired assets and assumed liabilities. In the months after closing, as the Corporation obtains additional information about these assets and liabilities, including through tangible and intangible asset appraisals, and as the Corporation learns more about the newly acquired business, it is able to refine the estimates of fair value and more accurately allocate the purchase price. Only items identified as of the acquisition date are considered for subsequent adjustment. The Corporation will make appropriate adjustments to the purchase price allocation prior to completion of the measurement period, as required.

No acquisitions were made during the three months ended March 31, 2018. During the three months ended March 31, 2017, the Corporation acquired two businesses for an aggregate purchase price of $239 million, both of which are described in more detail below.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition for those acquisitions consummated during the three months ended March 31, 2017.

Fair Value Disclosures [Abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS

8. FAIR VALUE OF FINANCIAL INSTRUMENTS

Forward Foreign Exchange and Currency Option Contracts

The Corporation has foreign currency exposure primarily in the United Kingdom, Europe, and Canada. The Corporation uses financial instruments, such as forward contracts, to hedge a portion of existing and anticipated foreign currency denominated transactions. The purpose of the Corporation’s foreign currency risk management program is to reduce volatility in earnings caused by exchange rate fluctuations. Guidance on accounting for derivative instruments and hedging activities requires companies to recognize all of the derivative financial instruments as either assets or liabilities at fair value in the Condensed Consolidated Balance Sheets based upon quoted market prices for comparable instruments.

Interest Rate Risks and Related Strategies

The Corporation’s primary interest rate exposure results from changes in U.S. dollar interest rates. The Corporation’s policy is to manage interest cost using a mix of fixed and variable rate debt. The Corporation periodically uses interest rate swaps to manage such exposures. Under these interest rate swaps, the Corporation exchanges, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount. The Corporation’s foreign exchange contracts and interest rate swaps are considered Level 2 instruments which are based on market based inputs or unobservable inputs and corroborated by market data such as quoted prices, interest rates, or yield curves.

Effects on Condensed Consolidated Balance Sheets

As of March 31, 2018 and December 31, 2017, the fair values of the asset and liability derivative instruments are immaterial.

Effects on Condensed Consolidated Statements of Earnings

Debt

The estimated fair value amounts were determined by the Corporation using available market information that is primarily based on quoted market prices for the same or similar issuances as of March 31, 2018. Accordingly, all of the Corporation’s debt is valued at a Level 2. The fair values described below may not be indicative of net realizable value or reflective of future fair values. Furthermore, the use of different methodologies to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

CONTINGENCIES AND COMMITMENTS	Mar. 31, 2018
Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES AND COMMITMENTS	13. CONTINGENCIES AND COMMITMENTS Legal Proceedings The Corporation has been named in a number of lawsuits that allege injury from exposure to asbestos. To date, the Corporation has not been found liable for or paid any material sum of money in settlement in any case. The Corporation believes its minimal use of asbestos in its past operations and the relatively non-friable condition of asbestos in its products makes it unlikely that it will face material liability in any asbestos litigation, whether individually or in the aggregate. The Corporation maintains insurance coverage for these potential liabilities and believes adequate coverage exists to cover any unanticipated asbestos liability. In December 2013, the Corporation, along with other unaffiliated parties, received a claim from Canadian Natural Resources Limited (CNRL) filed in the Court of Queen's Bench of Alberta, Judicial District of Calgary. The claim pertains to a January 2011 fire and explosion at a delayed coker unit at its Fort McMurray refinery that resulted in the injury of five CNRL employees, damage to property and equipment, and various forms of consequential loss, such as loss of profit, lost opportunities, and business interruption. The fire and explosion occurred when a CNRL employee bypassed certain safety controls and opened an operating coker unit. The total quantum of alleged damages arising from the incident has not been finalized, but is estimated to meet or exceed $1 billion. The Corporation maintains various forms of commercial, property and casualty, product liability, and other forms of insurance; however, such insurance may not be adequate to cover the costs associated with a judgment against us. In October 2017, all parties agreed in principle to participate in a formal mediation in late 2018 with the intention of settling this claim. In an effort to induce the parties to participate in the formal mediation, CNRL agreed to reduce its claim to approximately $400 million, which reflects the monetary amount of property damage incurred as a result of the fire and explosion. The Corporation is currently unable to estimate an amount, or range of potential losses, if any, from this matter. The Corporation believes that it has adequate legal defenses and intends to defend this matter vigorously. The Corporation's financial condition, results of operations, and cash flows could be materially affected during a future fiscal quarter or fiscal year by unfavorable developments or outcome regarding this claim. The Corporation is party to a number of other legal actions and claims, none of which individually or in the aggregate, in the opinion of management, are expected to have a material effect on the Corporation’s results of operations or financial position. Westinghouse Bankruptcy On March 29, 2017, WEC filed for Chapter 11 bankruptcy protection in the United States Bankruptcy Court for the Southern District of New York (the Court), Case No. 17-10751. The Court overseeing the Bankruptcy Case approved, on an interim basis, an $800 million Debtor-in-Possession Financing Facility to help WEC finance its business operations during the reorganization process. On January 4, 2018, WEC announced that it had agreed to be acquired by Brookfield Business Partners L.P (Brookfield) for approximately $4.6 billion with the acquisition expected to close in the third quarter of 2018. On March 27, 2018, the Court approved the sale to Brookfield. The acquisition is not expected to have a material impact on the Corporation’s financial condition or results of operations as WEC plans to continue operating in the ordinary course of business under existing senior management. The Corporation had approximately $2.9 million in pre-petition billings outstanding with WEC as of March 31, 2018. On March 27, 2018, the Court approved WEC's Plan of Reorganization, whereby the Corporation is expected to recover substantially all of its general unsecured claims inclusive of pre-petition billings. As it relates to post-petition work, the Corporation will continue to honor its executory contracts and expects to collect all amounts due. The Corporation will continue to monitor and evaluate the status of the WEC bankruptcy for potential impacts on its business. Letters of Credit and Other Financial Arrangements The Corporation enters into standby letters of credit agreements and guarantees with financial institutions and customers primarily relating to guarantees of repayment, future performance on certain contracts to provide products and services, and to secure advance payments from certain international customers. As of March 31, 2018 and December 31, 2017, there were $20.7 million and $21.3 million of stand-by letters of credit outstanding, respectively, and $15.0 million and $14.6 million of bank guarantees outstanding, respectively. In addition, the Corporation is required to provide the Nuclear Regulatory Commission financial assurance demonstrating its ability to cover the cost of decommissioning its Cheswick, Pennsylvania facility upon closure, though the Corporation does not intend to close this facility. The Corporation has provided this financial assurance in the form of a $56.0 million surety bond. AP1000 Program Within the Corporation’s Power segment, our Electro-Mechanical Division is the reactor coolant pump (RCP) supplier for the WEC AP1000 nuclear power plants under construction in China and the United States. The terms of the AP1000 China and United States contracts include liquidated damage penalty provisions for failure to meet contractual delivery dates if the Corporation caused the delay and the delay was not excusable. On October 10, 2013, the Corporation received a letter from WEC stating entitlements to the maximum amount of liquidated damages allowable under the AP1000 China contract of approximately $25 million. The Corporation would be liable for liquidated damages under the contract if certain contractual delivery dates were not met and if the Corporation was deemed responsible for the delay. As of March 31, 2018, the Corporation has not met certain contractual delivery dates under its AP 1000 contracts; however there are significant uncertainties as to which parties are responsible for the delays. The Corporation believes it has adequate legal defenses and intends to vigorously defend this matter. Given the uncertainties surrounding the responsibility for the delays, no accrual has been made for this matter as of March 31, 2018. As of March 31, 2018, the range of possible loss is $0 million to $31 million for the AP1000 U.S. contract, for a total range of possible loss is $0 million to $55.5 million.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis Of Accounting

Curtiss-Wright Corporation and its subsidiaries (the "Corporation" or the "Company") is a global, diversified manufacturing and service company that designs, manufactures, and overhauls precision components and provides highly engineered products and services to the aerospace, defense, power generation, and general industrial markets.

The unaudited condensed consolidated financial statements include the accounts of Curtiss-Wright and its majority-owned subsidiaries. All intercompany transactions and accounts have been eliminated.

The unaudited condensed consolidated financial statements of the Corporation have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted as permitted by such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of these financial statements.

Management is required to make estimates and judgments that affect the reported amount of assets, liabilities, revenue, and expenses and disclosure of contingent assets and liabilities in the accompanying financial statements. Actual results may differ from these estimates. The most significant of these estimates includes the estimate of costs to complete long-term contracts under the percentage-of-completion accounting methods, the estimate of useful lives for property, plant, and equipment, cash flow estimates used for testing the recoverability of assets, pension plan and postretirement obligation assumptions, estimates for inventory obsolescence, estimates for the valuation and useful lives of intangible assets, legal reserves, and the estimate of future environmental costs. Changes in estimates of contract sales, costs, and profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current and prior periods. Accordingly, the effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate. In the three month periods ended March 31, 2018 and 2017, there were no individual significant changes in estimated contract costs. In the opinion of management, all adjustments considered necessary for a fair presentation have been reflected in these financial statements.

The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Corporation’s 2017 Annual Report on Form 10-K. The results of operations for interim periods are not necessarily indicative of trends or of the operating results for a full year.

ASU 2017-07, Retirement Benefits - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost - On January 1, 2018, the Corporation adopted the amendments to ASC 715 that improve the presentation of net periodic pension and postretirement benefit costs. The Corporation retrospectively adopted the presentation of service cost separate from the other components of net periodic costs and included it as a component of employee compensation cost in operating income. The interest cost, expected return on assets, amortization of prior service costs, and net actuarial gain/loss components of net periodic benefit costs have been reclassified from operating income to other income, net. Additionally, the Corporation elected to apply the practical expedient which allows it to reclassify amounts disclosed previously in Note 15 of the Corporation's 2017 Annual Report on Form 10-K as the basis for applying retrospective presentation for comparative periods.

The effect of the retrospective change on the Corporation's Condensed Consolidated Statement of Earnings for the three months ended March 31, 2017, was as follows:

Recent accounting pronouncements to be adopted



Standard	Description	Effect on the condensed consolidated financial statements
ASU 2016-02 Leases	In February 2016, the FASB issued final guidance that will require lessees to put most leases on their balance sheets but recognize expenses on their income statements in a manner similar to today’s accounting.	The Corporation is currently evaluating the impact of the adoption of this standard on its Condensed Consolidated Financial Statements.
Date of adoption: January 1, 2019
ASU 2018-02 Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income	In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU permits the reclassification of tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the 2017 Tax Cuts and Jobs Act (the Tax Act). The standard will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted.	The Corporation is currently evaluating the impact of the adoption of this standard on its Condensed Consolidated Financial Statements.
Date of adoption: January 1, 2019

Impact from the Tax Act

In accordance with Staff Bulletin No. 118, Income Tax Implications of the Tax Cuts and Jobs Act, the Corporation recognized the income tax effects of the Tax Act in its consolidated financial statements for the year ended December 31, 2017. During the three months ended March 31, 2018, the Corporation recorded additional provisional tax expense of $6.5 million for foreign withholding taxes associated with the Tax Act. The Corporation expects to finalize any provisional amounts associated with the Tax Act over the next nine months based on ongoing assessment of its tax positions and other relevant data.
