PROPOSED TRANSACTION WITH FAIVE

PROPOSED TRANSACTION WITH FAIVELEY TRANSPORT S.A.	12 Months Ended
	Dec. 31, 2016
Business Combinations [Abstract]
PROPOSED TRANSACTION WITH FAIVELEY TRANSPORT S.A.	ACQUISITIONS Faiveley Transport On July 27, 2015, the Company announced plans to acquire all of the issued and outstanding shares of Faiveley Transport S.A. ("Faiveley Transport") under the terms of a Share Purchase Agreement (the "Share Purchase Agreement") and a Tender Offer Agreement (the "Tender Offer Agreement"). On October 24, 2016, the Company entered into amendments to the Share Purchase Agreement and the Tender Offer Agreement. Faiveley Transport is a leading global provider of value-added, integrated systems and services for the railway industry with annual sales of about $1.2 billion and more than 5,700 employees in 24 countries. Faiveley Transport supplies railway manufacturers, operators and maintenance providers with a range of valued-added, technology-based systems and services in Energy & Comfort (air conditioning, power collectors and converters, and passenger information), Access & Mobility (passenger access systems and platform doors), and Brakes and Safety (braking systems and couplers). The transaction has been structured in three steps: • Wabtec made an irrevocable offer to the owners of approximately 51% of Faiveley Transport's shares for a purchase price of €100 per share, payable between 25% and 45% in cash at the election of those shareholders with the remainder in common stock. • Upon completion of required labor group consultations, on October 6, 2015, the 51% shareholders entered into a definitive share purchase agreement, which was amended on October 24, 2016, and Faiveley Transport entered into the Tender Offer Agreement with Wabtec which was also amended on October 24, 2016. • Upon completing the share purchase under the Share Purchase Agreement, Wabtec commenced a tender offer for the remaining publicly traded Faiveley Transport shares. The public shareholders will have the option to elect to receive €100 per share in cash or Wabtec common stock. The common stock portion of the consideration is subject to a cap on issuance of Faiveley common shares that will be equivalent to the rates of cash and stock elected by the 51% owners. Wabtec intends to delist Faiveley Transport from Euronext after the tender offer if minority interests represent less than 5% . On November 30, 2016, the Company acquired majority ownership of Faiveley Transport, after completing the purchase of the Faiveley family’s ownership interest, which represented approximately 51% of outstanding share capital and approximately 49% of the outstanding voting shares of Faiveley Transport. Under the variable interest entity model the Company concluded that it is the primary beneficiary of Faiveley Transport as it possesses the power to direct the activities of Faiveley Transport that most significantly impact its economic performance and it possesses the obligation and right to absorb losses and benefits from Faiveley Transport; therefore, Faiveley Transport was consolidated by Wabtec under the variable interest model at acquisition. Based on the Company’s $84.77 stock price on November 30, 2016 , the aggregate value of consideration paid for the Faiveley Transport family’s ownership interest was $978.1 million , including $534.7 million in stock or approximately 6.3 million shares, $211.8 million in cash, $409.9 million in debt assumed, less $178.3 million in cash acquired. The Company launched a tender offer for the remaining publicly traded Faiveley Transport shares in December 2016. Through the tender offer, the public shareholders of Faiveley Transport will have the option to elect to receive €100 per share of Faiveley Transport in cash or 1.1538 Wabtec common shares per share of Faiveley Transport. On February 3, 2017, the initial cash tender offer was closed which resulted in the Company acquiring an additional 27.5% of outstanding share capital of Faiveley Transport for approximately $411.8 million in cash and $25.2 million in Wabtec stock. The tender offer will be reopened with dates and duration to be determined by the French regulator. The total purchase price for 100% of the shares of Faiveley Transport is approximately $1.7 billion , including assumed debt and net of cash acquired. The approximate $1.0 billion cash portion of the transaction is being funded from cash on hand, the net proceeds from a recent $750 million senior notes offering and the company’s existing revolving credit facility and term note. The $744.7 million included as deposits in escrow on the consolidated balance sheet at December 31, 2016 is cash designated for use as consideration for the tender offer. The Company’s 2016 operating results include the results from Faiveley Transport following the November 30, 2016 acquisition date. The fair value of the noncontrolling interest was preliminarily determined using the market price of Faiveley Transport’s publicly traded common stock multiplied by the number of publicly traded common shares outstanding at the acquisition date and is considered Level 1. The fair values of the assets acquired and liabilities assumed are preliminarily determined using the income, cost and market approaches. The fair value measurements were primarily based on significant inputs that are not observable in the market and are considered Level 3. The December 31, 2016 consolidated balance sheet includes the assets and liabilities of Faiveley Transport, which have been measured at fair value. The following table summarizes the preliminary estimated fair values of the Faiveley Transport assets acquired and liabilities assumed. In thousands Assets acquired Cash and cash equivalents $ 178,318 Accounts receivable 385,754 Inventories 207,151 Other current assets 66,152 Property, plant, and equipment 161,663 Goodwill 1,188,296 Trade names 333,823 Customer Relationships 255,354 Patents 1,201 Other noncurrent assets 141,756 Total assets acquired 2,919,468 Liabilities assumed Current liabilities 653,679 Debt 409,899 Other noncurrent liabilities 349,074 Total liabilities assumed 1,412,652 Noncontrolling interest 760,343 Net assets acquired $ 1,506,816 These estimates are preliminary in nature and subject to adjustments, which could be material. Any necessary adjustments will be finalized within one year from the date of acquisition. Substantially all of the accounts receivable acquired are expected to be collectible. Included in current liabilities is $25.9 million of accrued compensation for acquired share-based stock plans that are obligated to be settled in cash. Contingent liabilities assumed as part of the transaction were not material. These contingent liabilities are related to environmental, legal and tax matters. Contingent liabilities are recorded at fair value in purchase accounting, aside from those pertaining to uncertainty in income taxes which are an exception to the fair value basis of accounting. Goodwill was calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of the net assets acquired, and represents the future economic benefits, including synergies and assembled workforce, that we expect to achieve as a result of the acquisition. Purchased goodwill is not expected to be deductible for tax purposes. The goodwill has been preliminarily allocated to our Transit segment. For the 31 day period ended December 31, 2016, the Company’s consolidated statement of income included $110.8 million of revenues and $0.6 million of operating income from Faiveley Transport. Additionally, a net tax benefit of $30.6 million was recognized from Faiveley Transport primarily due to an enacted legislative change in the French corporate tax rate and the benefit from charges related to the repayment of debt acquired from Faiveley Transport. Acquisition related costs were $38.9 million in 2016 and are included in selling, general and administrative expenses on the consolidated statements of income.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of the Company and all subsidiaries that it controls. For consolidated subsidiaries in which the Company's ownership is less than 100%, the outside shareholders' interests are shown as noncontrolling interests. These statements have been prepared in accordance with U.S. generally accepted accounting principles. Sales between subsidiaries are billed at prices consistent with sales to third parties and are eliminated in consolidation. Cash Equivalents Cash equivalents are highly liquid investments purchased with an original maturity of three months or less. Allowance for Doubtful Accounts The allowance for doubtful accounts receivable reflects our best estimate of probable losses inherent in our receivable portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The allowance for doubtful accounts was $7.3 million and $5.6 million as of December 31, 2016 and 2015 , respectively. Inventories Inventories are stated at the lower of cost or market. Cost is determined under the first-in, first-out (FIFO) method. Inventory costs include material, labor and overhead. Property, Plant and Equipment Property, plant and equipment additions are stated at cost. Expenditures for renewals and improvements are capitalized. Expenditures for ordinary maintenance and repairs are expensed as incurred. The Company computes book depreciation principally on the straight-line method. Accelerated depreciation methods are utilized for income tax purposes. Leasing Arrangements The Company conducts a portion of its operations from leased facilities and finances certain equipment purchases through lease agreements. In those cases in which the lease term approximates the useful life of the leased asset or the lease meets certain other prerequisites, the leasing arrangement is classified as a capital lease. The remaining arrangements are treated as operating leases. Goodwill and Intangible Assets Goodwill and other intangible assets with indefinite lives are not amortized. Other intangibles (with definite lives) are amortized on a straight-line basis over their estimated economic lives. Amortizable intangible assets are reviewed for impairment when indicators of impairment are present. The Company tests goodwill and indefinite-lived intangible assets for impairment at the reporting unit level and at least annually. The Company performs its annual impairment test during the fourth quarter after the annual forecasting process is completed, and also tests for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Periodically, Management of the Company assesses whether or not an indicator of impairment is present that would necessitate an impairment analysis be performed. For 2016, the Company opted to proceed directly to the two-step quantitative impairment test for all reporting units with goodwill. In the first step of the quantitative assessment, our assets and liabilities, including existing goodwill and other intangible assets, are assigned to the identified reporting units to determine the carrying value of the reporting units. The income approach and the market approach are weighted at 45% and 55%, respectively, in arriving at fair value, which the Company has applied consistently. The discounted cash flow model requires several assumptions including future sales growth, EBIT (earnings before interest and taxes) margins and capital expenditures for the reporting units. The discounted cash flow model also requires the use of a discount rate and a terminal revenue growth rate (the revenue growth rate for the period beyond the years forecasted by the reporting units), as well as projections of future operating margins. The market approach requires several assumptions including EBITDA (earnings before interest, taxes, depreciation and amortization) multiples for comparable companies that operate in the same markets as the Company’s reporting units. The estimated fair value of all reporting units was substantially in excess of its respective carrying value, which resulted in a conclusion that no impairment existed. Additionally, the Company proceeded directly to the quantitative impairment test for some trade names with indefinite lives. The fair value of all trade names subject to the quantitative impairment test exceeded its respective carrying value, resulting in a conclusion that no impairment existed. For trade names not subject to the quantitative testing, the Company opted to perform a qualitative trade name impairment assessment and determined from the qualitative assessment that it was not more likely than not that the estimated fair values of the trade names were less than their carrying values; therefore, no further analysis was required. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a trade name is less than its carrying amount, we assess relevant events and circumstances that may impact the fair value and the carrying amount of the trade name. The identification of relevant events and circumstances and how these may impact a trade name’s fair value or carrying amount involve significant judgments and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. Warranty Costs Warranty costs are accrued based on Management’s estimates of repair or upgrade costs per unit and historical experience. Warranty expense was $28.9 million , $35.4 million and $34.1 million for 2016 , 2015 and 2014 , respectively. Accrued warranty was $139.0 million and $92.1 million at December 31, 2016 and 2015 , respectively. Income Taxes Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws. The provision for income taxes includes federal, state and foreign income taxes. Stock-Based Compensation The Company recognizes compensation expense for stock-based compensation based on the grant date fair value amortized ratably over the requisite service period following the date of grant. Financial Derivatives and Hedging Activities The Company has entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. Foreign currency forward contracts are agreements with a counterparty to exchange two distinct currencies at a set exchange rate for delivery on a set date at some point in the future. There is no exchange of funds until the delivery date. At the delivery date the Company can either take delivery of the currency or settle on a net basis. For further information regarding the foreign currency forward contracts, see Footnote 17. To reduce the impact of interest rate changes on a portion of its variable-rate debt, the Company has entered into an interest rate swap agreement with a notional value of $150 million . As of December 31, 2016 , the Company has recorded a current liability of $3.9 million and a corresponding offset in accumulated other comprehensive loss of $2.3 million , net of tax, related to these agreements. For further information regarding the interest rate swap agreement, see Footnote 8. Foreign Currency Translation Assets and liabilities of foreign subsidiaries, except for the Company’s Mexican operations whose functional currency is the U.S. Dollar, are translated at the rate of exchange in effect on the balance sheet date while income and expenses are translated at the average rates of exchange prevailing during the period. Foreign currency gains and losses resulting from transactions, and the translation of financial statements are recorded in the Company’s consolidated financial statements based upon the provisions of Accounting Standards Codification (“ASC”) 830, “Foreign Currency Matters.” The effects of currency exchange rate changes on intercompany transactions and balances of a long-term investment nature are accumulated and carried as a component of accumulated other comprehensive loss. The effects of currency exchange rate changes on intercompany transactions that are denominated in a currency other than an entity’s functional currency are charged or credited to earnings. Foreign exchange transaction losses recognized in other (expense) income, net were $4.0 million , $4.7 million and $2.4 million for 2016 , 2015 and 2014 , respectively. Noncontrolling Interests In accordance with ASC 810, the Company has classified noncontrolling interests as equity on our condensed consolidated balance sheets as of December 31, 2016 and 2015 . Net income attributable to noncontrolling interests for the year ended December 31, 2016 was $8.5 million . Net income attributable to noncontrolling interests for the years ended December 31, 2015 and 2014 was not material. Other comprehensive income attributable to noncontrolling interests for the years ended December 31, 2016, 2015 and 2014 was not material. Revenue Recognition Revenue is recognized in accordance with ASC 605 “Revenue Recognition,” The Company recognizes revenue when the following criteria are met: 1) persuasive evidence of an arrangement exists; 2) delivery has occurred; 3) an established sales price has been set with the customer; 4) collection of the sale revenue from the customer is reasonably assured; and 5) no contingencies exist. Delivery is considered to have occurred when the customer assumes the risk and rewards of ownership. The Company estimates and records provisions for quantity rebates and sales returns and allowances as an offset to revenue in the same period the related revenue is recognized, based upon its experience. These items are included as a reduction in deriving net sales. In general, the Company recognizes revenues on long-term contracts based on the percentage of completion method of accounting. The units-of-delivery method or other input-based or output-based measures, as appropriate, are used to measure the progress toward completion of individual contracts. Contract revenues and cost estimates are reviewed and revised quarterly at a minimum and adjustments are reflected in the accounting period as such amounts are determined. Provisions are made currently for estimated losses on uncompleted contracts. Unbilled accounts receivables were $274.9 million and $103.8 million , customer deposits were $256.6 million and $106.1 million , and provisions for loss contracts were $60.5 million and $11.8 million at December 31, 2016 and 2015 , respectively. Certain pre-production costs relating to long-term production and supply contracts have been deferred and will be recognized over the life of the contracts. Deferred pre-production costs were $29.4 million and $30.3 million at December 31, 2016 and 2015 , respectively. Significant Customers and Concentrations of Credit Risk The Company’s trade receivables are from rail and transit industry original equipment manufacturers, Class I railroads, railroad carriers and commercial companies that utilize rail cars in their operations, such as utility and chemical companies. No one customer accounted for more than 10% of the Company’s consolidated net sales in 2016 , 2015 or 2014 . Shipping and Handling Fees and Costs All fees billed to the customer for shipping and handling are classified as a component of net revenues. All costs associated with shipping and handling are classified as a component of cost of sales. Research and Development Research and development costs are charged to expense as incurred. For the years ended December 31, 2016 , 2015 and 2014 , the Company incurred costs of approximately $71.4 million , $71.2 million , and $61.9 million , respectively. Employees As of December 31, 2016 , approximately 35% of the Company’s workforce was covered by collective bargaining agreements. These agreements are generally effective from 2017 through 2019. Agreements expiring in 2017 cover approximately 20% of the Company’s workforce. Earnings Per Share Basic and diluted earnings per common share is computed in accordance with ASC 260 “Earnings Per Share.” Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and included in the computation of earnings per share pursuant to the two-class method included in ASC 260-10-55. (See Note 11 “Earnings Per Share” included herein) Reclassifications Certain prior year amounts have been reclassified, where necessary, to conform to the current year presentation. Refer to Recently Adopted Accounting Pronouncements below. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates. On an ongoing basis, Management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates. Recently Issued Accounting Pronouncements In November 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-18 "Statement of Cash Flows (Topic 230): Restricted Cash". The amendments in this update require a statement of cash flows explain the change during the period in total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The ASU is effective for public companies in the fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. The ASU simplifies several aspects for the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The ASU is effective for public companies in the fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. In accordance with this update, the Company will recognize all excess tax benefits and tax deficiencies from share-based payment awards as income tax expense or benefit in the income statement (currently excess tax benefits are recognized in additional paid-in capital on the consolidated balance sheet). Additionally, upon adoption of this update the Company will classify excess income tax benefits from exercise of stock options as an operating activity on the consolidated statement of cash flows (currently income tax benefits from the exercise of stock options are classified as a financing activity). In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 814)" which requires lessees to recognize a right of use asset and lease liability on the balance sheet for all leases with terms longer than 12 months. For leases with terms less than 12 months, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize a right of use asset and lease liability. The ASU is effective for public companies in the fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-9, “Revenue from Contract with Customers.” The ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Board voted to propose that the standard would take effect for reporting periods beginning after December 15, 2017 and that early adoption would be allowed as of the original effective date. The impact of adopting the new standard on 2016 and 2015 net sales and operating income is not expected to be material. The Company also does not expect a material impact to the consolidated balance sheet. The impact to results is not anticipated to be material because the analysis of the Company's current contracts under the new revenue recognition standard supports the recognition of revenue over time under the cost-to-cost method for the majority of our contracts, which is consistent with our current revenue recognition model. The Company plans to adopt this accounting standard update using the modified retrospective method, with the cumulative effect of initially applying this update recognized in the first reporting period of 2018. The Company is in the process of drafting an updated accounting policy, evaluating new disclosure requirements and identifying and implementing appropriate changes to its business processes, systems and controls to support recognition and disclosure under the new guidance. Recently Adopted Accounting Pronouncements In November 2015, the FASB issued ASU No. 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes" which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities to be classified as noncurrent on the balance sheet. The Company elected to early adopt this ASU as of December 31, 2016; therefore, all deferred income tax assets and liabilities are classified in the noncurrent deferred income taxes line-items on the consolidated balance sheet. Additionally, the Company elected to update the December 31, 2015 balance sheet for comparative purposes. As a result, $71.7 million of current deferred income tax assets (previously reported in current deferred income taxes) and $0.8 million of current deferred income tax liabilities (previously reported in other accrued liabilities) were reclassified to the other noncurrent assets and noncurrent deferred tax line items, respectively, on the December 31, 2015 consolidated balance sheet. In September 2015, the FASB issued ASU No. 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments" which require an acquirer 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 effect on earnings of changes in depreciation, amortization or other income effects as a result of the change to the provisional amounts are to be recorded in the same period's financial statements and calculated as if the accounting had been completed at the acquisition date. The Company adopted this ASU on January 1, 2016. The adoption of this ASU did not have a material impact on the consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-3, “Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-3”) which changes the presentation of debt issuance costs in financial statements to present such costs as a direct deduction from the related debt liability rather than as an asset. ASU 2015-3 became effective for public companies during interim and annual reporting periods beginning after December 15, 2015. The Company retrospectively adopted this ASU on January 1, 2016. The adoption of this ASU did not have a material impact on the consolidated financial statements.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS Faiveley Transport On July 27, 2015, the Company announced plans to acquire all of the issued and outstanding shares of Faiveley Transport S.A. ("Faiveley Transport") under the terms of a Share Purchase Agreement (the "Share Purchase Agreement") and a Tender Offer Agreement (the "Tender Offer Agreement"). On October 24, 2016, the Company entered into amendments to the Share Purchase Agreement and the Tender Offer Agreement. Faiveley Transport is a leading global provider of value-added, integrated systems and services for the railway industry with annual sales of about $1.2 billion and more than 5,700 employees in 24 countries. Faiveley Transport supplies railway manufacturers, operators and maintenance providers with a range of valued-added, technology-based systems and services in Energy & Comfort (air conditioning, power collectors and converters, and passenger information), Access & Mobility (passenger access systems and platform doors), and Brakes and Safety (braking systems and couplers). The transaction has been structured in three steps: • Wabtec made an irrevocable offer to the owners of approximately 51% of Faiveley Transport's shares for a purchase price of €100 per share, payable between 25% and 45% in cash at the election of those shareholders with the remainder in common stock. • Upon completion of required labor group consultations, on October 6, 2015, the 51% shareholders entered into a definitive share purchase agreement, which was amended on October 24, 2016, and Faiveley Transport entered into the Tender Offer Agreement with Wabtec which was also amended on October 24, 2016. • Upon completing the share purchase under the Share Purchase Agreement, Wabtec commenced a tender offer for the remaining publicly traded Faiveley Transport shares. The public shareholders will have the option to elect to receive €100 per share in cash or Wabtec common stock. The common stock portion of the consideration is subject to a cap on issuance of Faiveley common shares that will be equivalent to the rates of cash and stock elected by the 51% owners. Wabtec intends to delist Faiveley Transport from Euronext after the tender offer if minority interests represent less than 5% . On November 30, 2016, the Company acquired majority ownership of Faiveley Transport, after completing the purchase of the Faiveley family’s ownership interest, which represented approximately 51% of outstanding share capital and approximately 49% of the outstanding voting shares of Faiveley Transport. Under the variable interest entity model the Company concluded that it is the primary beneficiary of Faiveley Transport as it possesses the power to direct the activities of Faiveley Transport that most significantly impact its economic performance and it possesses the obligation and right to absorb losses and benefits from Faiveley Transport; therefore, Faiveley Transport was consolidated by Wabtec under the variable interest model at acquisition. Based on the Company’s $84.77 stock price on November 30, 2016 , the aggregate value of consideration paid for the Faiveley Transport family’s ownership interest was $978.1 million , including $534.7 million in stock or approximately 6.3 million shares, $211.8 million in cash, $409.9 million in debt assumed, less $178.3 million in cash acquired. The Company launched a tender offer for the remaining publicly traded Faiveley Transport shares in December 2016. Through the tender offer, the public shareholders of Faiveley Transport will have the option to elect to receive €100 per share of Faiveley Transport in cash or 1.1538 Wabtec common shares per share of Faiveley Transport. On February 3, 2017, the initial cash tender offer was closed which resulted in the Company acquiring an additional 27.5% of outstanding share capital of Faiveley Transport for approximately $411.8 million in cash and $25.2 million in Wabtec stock. The tender offer will be reopened with dates and duration to be determined by the French regulator. The total purchase price for 100% of the shares of Faiveley Transport is approximately $1.7 billion , including assumed debt and net of cash acquired. The approximate $1.0 billion cash portion of the transaction is being funded from cash on hand, the net proceeds from a recent $750 million senior notes offering and the company’s existing revolving credit facility and term note. The $744.7 million included as deposits in escrow on the consolidated balance sheet at December 31, 2016 is cash designated for use as consideration for the tender offer. The Company’s 2016 operating results include the results from Faiveley Transport following the November 30, 2016 acquisition date. The fair value of the noncontrolling interest was preliminarily determined using the market price of Faiveley Transport’s publicly traded common stock multiplied by the number of publicly traded common shares outstanding at the acquisition date and is considered Level 1. The fair values of the assets acquired and liabilities assumed are preliminarily determined using the income, cost and market approaches. The fair value measurements were primarily based on significant inputs that are not observable in the market and are considered Level 3. The December 31, 2016 consolidated balance sheet includes the assets and liabilities of Faiveley Transport, which have been measured at fair value. The following table summarizes the preliminary estimated fair values of the Faiveley Transport assets acquired and liabilities assumed. In thousands Assets acquired Cash and cash equivalents $ 178,318 Accounts receivable 385,754 Inventories 207,151 Other current assets 66,152 Property, plant, and equipment 161,663 Goodwill 1,188,296 Trade names 333,823 Customer Relationships 255,354 Patents 1,201 Other noncurrent assets 141,756 Total assets acquired 2,919,468 Liabilities assumed Current liabilities 653,679 Debt 409,899 Other noncurrent liabilities 349,074 Total liabilities assumed 1,412,652 Noncontrolling interest 760,343 Net assets acquired $ 1,506,816 These estimates are preliminary in nature and subject to adjustments, which could be material. Any necessary adjustments will be finalized within one year from the date of acquisition. Substantially all of the accounts receivable acquired are expected to be collectible. Included in current liabilities is $25.9 million of accrued compensation for acquired share-based stock plans that are obligated to be settled in cash. Contingent liabilities assumed as part of the transaction were not material. These contingent liabilities are related to environmental, legal and tax matters. Contingent liabilities are recorded at fair value in purchase accounting, aside from those pertaining to uncertainty in income taxes which are an exception to the fair value basis of accounting. Goodwill was calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of the net assets acquired, and represents the future economic benefits, including synergies and assembled workforce, that we expect to achieve as a result of the acquisition. Purchased goodwill is not expected to be deductible for tax purposes. The goodwill has been preliminarily allocated to our Transit segment. For the 31 day period ended December 31, 2016, the Company’s consolidated statement of income included $110.8 million of revenues and $0.6 million of operating income from Faiveley Transport.

The 2016 Notes are senior unsecured obligations of the Company and rank pari passu with all existing and future senior debt and senior to all existing and future subordinated indebtedness of the Company. The indenture under which the 2016 Notes were issued contains covenants and restrictions which limit among other things, the following: the incurrence of indebtedness, payment of dividends and certain distributions, sale of assets, change in control, mergers and consolidations and the incurrence of liens. The Company is in compliance with the restrictions and covenants in the indenture under which the 2016 Notes were issued and expects that these restrictions and covenants will not be any type of limiting factor in executing our operating activities. 4.375% Senior Notes Due August 2023 In August 2013, the Company issued $250.0 million of Senior Notes due in 2023 (the “2013 Notes”).

The Company incurred $2.6 million of deferred financing costs related to the issuance of the 2013 Notes. The 2013 Notes are senior unsecured obligations of the Company and rank pari passu with all existing and future senior debt and senior to all existing and future subordinated indebtedness of the Company. The indenture under which the 2013 Notes were issued contains covenants and restrictions which limit among other things, the following: the incurrence of indebtedness, payment of dividends and certain distributions, sale of assets, change in control, mergers and consolidations and the incurrence of liens. The Company is in compliance with the restrictions and covenants in the indenture under which the 2013 Notes were issued and expects that these restrictions and covenants will not be any type of limiting factor in executing our operating activities. 2016 Refinancing Credit Agreement On June 22, 2016 , the Company amended its existing revolving credit facility with a consortium of commercial banks. This “2016 Refinancing Credit Agreement” provides the Company with a $1.2 billion , 5 year revolving credit facility and a $400.0 million delayed draw term loan (the “Term Loan”). The Company incurred approximately $3.3 million of deferred financing cost related to the 2016 Refinancing Credit Agreement. The facility expires on June 22, 2021 . The 2016 Refinancing Credit Agreement borrowings bear variable interest rates indexed as described below. At December 31, 2016 , the Company had available bank borrowing capacity, net of $20.2 million of letters of credit, of approximately $783.7 million , subject to certain financial covenant restrictions. The Term Loan was drawn on November 25, 2016. The Company incurred a 10 basis point commitment fee from June 22, 2016 until the initial draw on November 25, 2016. Under the 2016 Refinancing Credit Agreement, the Company may elect a Base Rate of interest for U.S. Dollar denominated loans or, for certain currencies, an interest rate based on the London Interbank Offered Rate (“LIBOR”) of interest, or other rates appropriate for such currencies (in any case, “the Alternate Rate”). The Base Rate adjusts on a daily basis and is the greater of the Federal Funds Effective Rate plus 0.50% per annum, the PNC, N.A. prime rate or the Daily LIBOR Rate plus 100 basis points, plus a margin that ranges from 0 to 75 basis points. The Alternate Rate is based on the quoted rates specific to the applicable currency, plus a margin that ranges from 75 to 175 basis points. Both the Base Rate and Alternate Rate margins are dependent on the Company’s consolidated total indebtedness to EBITDA ratios. The initial Base Rate margin is 0 basis points and the Alternate Rate margin is 175 basis points . At December 31, 2016, the weighted average interest rate on the Company’s variable rate debt was 2.51% . On January 12, 2012, the Company entered into a forward starting interest rate swap agreement with a notional value of $150.0 million . The effective date of the interest rate swap agreement is July 31, 2013, and the termination date was November 7, 2016. The impact of the interest rate swap agreement converted a portion of the Company’s outstanding debt from a variable rate to a fixed-rate borrowing. During the term of the interest rate swap agreement the interest rate on the notional value was fixed at 1.415% plus the Alternate Rate margin. On June 5, 2014, the Company entered into a forward starting interest rate swap agreement with a notional value of $150.0 million . The effective date of the interest rate swap agreement is November 7, 2016, and the termination date is December 19, 2018. The impact of the interest rate swap agreement converts a portion of the Company’s outstanding debt from a variable rate to a fixed-rate borrowing. During the term of the interest rate swap agreement the interest rate on the notional value will be fixed at 2.56% plus the Alternate Rate margin. As for these agreements, the Company is exposed to credit risk in the event of nonperformance by the counterparties. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparties are large financial institutions with excellent credit ratings and history of performance. The Company currently believes the risk of nonperformance is negligible. The 2016 Refinancing Credit Agreement limits the Company’s ability to declare or pay cash dividends and prohibits the Company from declaring or making other distributions, subject to certain exceptions. The 2016 Refinancing Credit Agreement contains various other covenants and restrictions including the following limitations: incurrence of additional indebtedness; mergers, consolidations, sales of assets and acquisitions; additional liens; sale and leasebacks; permissible investments, loans and advances; certain debt payments; and imposes a minimum interest expense coverage ratio of 3.0 and a maximum debt to EBITDA ratio of 3.25 . The Company is in compliance with the restrictions and covenants of the 2016 Refinancing Credit Agreement and does not expect that these measurements will limit the Company in executing our operating activities. 2013 Refinancing Credit Agreement On December 19, 2013, the Company amended its then existing revolving credit facility with a consortium of commercial banks. This “2013 Refinancing Credit Agreement” provided the Company with an $800.0 million , 5 -year revolving credit facility. The Company incurred approximately $1.0 million of deferred financing cost related to the 2013 Refinancing Credit Agreement. The 2013 Refinancing Credit Agreement was replaced by the 2016 Refinancing Credit Agreement. Under the 2013 Refinancing Credit Agreement, the Company could have elected a Base Rate of interest for U.S. Dollar denominated loans or, for certain currencies, an interest rate based on the LIBOR of interest, or other rates appropriate for such currencies (in any case, “the Alternate Rate”). The Base Rate adjusted on a daily basis and was the greater of the Federal Funds Effective Rate plus 0.5% per annum, the PNC, N.A. prime rate or the Daily LIBOR Rate plus 100 basis points, plus a margin that ranged from 0 to 75 basis points. The Alternate Rate was based on the quoted rates specific to the applicable currency, plus a margin that ranged from 75 to 175 basis points. Both the Base Rate and Alternate Rate margins were dependent on the Company’s consolidated total indebtedness to EBITDA ratios. Schuldschein Loan, Due 2016 In conjunction with the acquisition of Faiveley Transport, Wabtec acquired $137.2 million of a Schuldshein private placement loan which was originally issued by Faiveley Transport on March 5, 2014 in Germany, in which approximately 20 international investors participated. This loan is denominated in euros. Subsequent to the acquisition of Faiveley Transport, the Company repaid $38.5 million of the outstanding Schuldshein loan. The remaining balance of $98.7 million as of December 31, 2016 is divided into three tranches with original maturities of 5 , 7 and 10 years bearing fixed or variable rates. A summary of the tranches as of December 31, 2016 are as follows: Maturity Rate Amounts March 2019 Euribor 6 months + 1.30% $ 15,831 March 2019 2.32% 2,630 December 2020 3.04% 21,110 March 2021 Euribor 6 months + 1.65% 23,220 March 2021 3.07% 14,770 March 2024 4.00% 21,110 Total $ 98,671 The Schuldschein loan is senior unsecured and ranks pari passu with all and future senior debt and senior to all existing and future subordinated indebtedness of Faiveley Transport. The Schuldschein loan agreement contains covenants and undertakings which limit among other things, the following: factoring of receivables, the incurrence of indebtedness, sale of assets, change of control, mergers and consolidations and the incurrence of liens. At December 31, 2016, Faiveley Transport is in compliance with the undertakings and covenants contained in the loan agreement. In January 2017, the Company notified investors of its intention to repay the variable tranches of the private placement in full totaling $39.1 million on March 6, 2017 and its desire to repay the fixed tranches of the private placement in full. As of February 28, 2017 , the Company has repaid $18.7 million of the private placement fixed tranches outstanding at December 31, 2016 .

Objectives include maximizing long-term return at acceptable risk levels and diversifying among asset classes. Asset allocation targets are based on periodic asset liability study results which help determine the appropriate investment strategies. The investment policies permit variances from the targets within certain parameters. The plan assets consist primarily of equity security funds, debt security funds, and temporary cash and cash equivalent investments. The assets held in these funds are generally actively managed and are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. Generally, all plan assets are considered Level 2 based on the fair value valuation hierarchy (See Note 18 “Fair Value Measurement” included herein). Plan assets by asset category at December 31, 2016 and 2015 are as follows: U.S. International In thousands 2016 2015 2016 2015 Pension Plan Assets Equity security funds $ 17,446 $ 20,275 $ 92,201 $ 87,321 Debt security funds and other 17,038 16,441 145,003 77,173 Cash and cash equivalents 1,318 924 4,079 3,575 Fair value of plan assets $ 35,802 $ 37,640 $ 241,283 $ 168,069 The U.S., Canadian and German pension plans have a target asset allocation of 50% equity securities and 50% debt securities. The United Kingdom plan has a target asset allocation of 30% equity securities and 70% debt securities. Investment policies are determined by the respective Plan’s Pension Committee and set forth in its Investment Policy. Rebalancing of the asset allocation occurs on a quarterly basis. Cash Flows The Company’s funding methods are based on governmental requirements and differ from those methods used to recognize pension expense. The Company expects to contribute $7.1 million and $0.5 million to the international and U.S. plans, respectively, during 2017 . Benefit payments expected to be paid to plan participants are as follows: In thousands U.S. International Year ended December 31, 2017 $ 3,514 $ 11,406 2018 3,347 11,088 2019 3,372 11,415 2020 3,357 12,090 2021 3,385 12,416 2022 through 2026 15,151 68,114 Post Retirement Benefit Plans In addition to providing pension benefits, the Company has provided certain unfunded postretirement health care and life insurance benefits for a portion of North American employees. The Company is not obligated to pay health care and life insurance benefits to individuals who had retired prior to 1990. The Company uses a December 31 measurement date for all post retirement plans.

A 1.0% increase in the assumed health care cost trend rate will increase the service and interest cost components of the expense recognized for the U.S. and international post-retirement plans by less than $0.1 million for 2016, and increase the accumulated post-retirement benefit obligation by less than $0.1 million and $0.3 million, respectively. A 1.0% decrease in the assumed health care cost trend rate will decrease the service and interest cost components of the expense recognized for the U.S. and international post-retirement plans by less than $0.1 million for 2016 , and decrease the accumulated post-retirement benefit obligation by less than $0.1 million and $0.2 million, respectively.

At December 31, 2016 and 2015 , the plan held on behalf of its participants about 551,482 shares with a market value of $45.8 million , and 632,523 shares with a market value of $45.0 million , respectively. Additionally, the Company has stock option based benefit and other plans further described in Note 12. The Company contributes to several multi-employer defined benefit pension plans under collective bargaining agreements that cover certain of its union-represented employees. The risks of participating in such plans are different from the risks of single-employer plans. Assets contributed to a multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer ceases to contribute to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. If the Company ceases to have an obligation to contribute to the multi-employer plan in which it had been a contributing employer, it may be required to pay to the plan an amount based on the underfunded status of the plan and on the history of the Company’s participation in the plan prior to the cessation of its obligation to contribute. The amount that an employer that has ceased to have an obligation to contribute to a multi-employer plan is required to pay to the plan is referred to as a withdrawal liability. The Company’s participation in multi-employer plans for the year ended December 31, 2016 is outlined in the table below. For plans that are not individually significant to the Company, the total amount of contributions is presented in the aggregate.

A plan in the “red” zone has been determined to be in “critical status”, based on criteria established under the Internal Revenue Code (“Code”), and is generally less than 65% funded. A plan in the “yellow” zone has been determined to be in “endangered status”, based on criteria established under the Code, and is generally less than 80% funded. A plan in the “green” zone has been determined to be neither in “critical status” nor in “endangered status”, and is generally at least 80% funded.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company is responsible for filing consolidated U.S., foreign and combined, unitary or separate state income tax returns. The Company is responsible for paying the taxes relating to such returns, including any subsequent adjustments resulting from the redetermination of such tax liabilities by the applicable taxing authorities. The components of the income from operations before provision for income taxes for the Company’s domestic and foreign operations for the years ended December 31 are provided below: For the year ended In thousands 2016 2015 2014 Domestic $ 276,218 $ 461,394 $ 343,180 Foreign 136,619 123,974 164,675 Income from operations before income taxes $ 412,837 $ 585,368 $ 507,855 Undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $1,256.2 million at December 31, 2016 . Those earnings are considered to be indefinitely reinvested; accordingly, no provision for U.S. federal and state income taxes has been provided thereon. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with its hypothetical calculation. The consolidated provision for income taxes included in the Statement of Income consisted of the following: For the year ended December 31, In thousands 2016 2015 2014 Current taxes Federal $ 72,317 $ 141,245 $ 108,782 State 9,953 16,072 17,091 Foreign 27,391 24,442 37,356 109,661 181,759 163,229 Deferred taxes Federal 11,013 9,606 2,287 State 1,953 770 1,404 Foreign (23,194 ) (5,395 ) (10,745 ) (10,228 ) 4,981 (7,054 ) Total provision $ 99,433 $ 186,740 $ 156,175 A reconciliation of the United States federal statutory income tax rate to the effective income tax rate on operations for the years ended December 31 is provided below: For the year ended December 31, In thousands 2016 2015 2014 U.S. federal statutory rate 35.0 % 35.0 % 35.0 % State taxes 2.1 % 2.0 % 2.2 % Tax reserves (0.2 )% (0.4 )% 0.3 % Foreign (4.3 )% (2.1 )% (4.2 )% Research and development credit (1.0 )% (0.4 )% (0.5 )% Manufacturing deduction (1.8 )% (2.3 )% (1.8 )% France tax rate change (6.5 )% — % — % Transaction costs related to acquisitions 1.5 % — % — % Other, net (0.7 )% 0.1 % (0.2 )% Effective rate 24.1 % 31.9 % 30.8 % The 6.5% decrease in the effective tax rate due to the France tax rate change was the result of adopted tax legislation that reduces the corporate income tax rate in France from 33.3% to 28.0% over the period 2017 to 2020. The 1.5% increase in the effective tax rate due to Transaction costs related to acquisitions was primarily related to nondeductible costs associated with the acquisition of Faiveley Transport. Deferred income taxes result from temporary differences in the recognition of income and expense for financial and income tax reporting purposes. These deferred income taxes will be recognized as future tax benefits or costs when the temporary differences reverse. Components of deferred tax assets and liabilities were as follows: December 31, In thousands 2016 2015 Deferred income tax assets: Accrued expenses and reserves $ 26,117 $ 39,426 Warranty reserve 24,131 24,544 Deferred compensation/employee benefits 25,755 24,950 Pension and postretirement obligations 25,595 15,507 Inventory 22,579 18,664 Net operating loss carry forwards 59,416 25,636 Tax credit carry forwards 621 959 Other 2,317 — Gross deferred income tax assets 186,531 149,686 Valuation allowance 21,418 12,623 Total deferred income tax assets 165,113 137,063 Deferred income tax liabilities: Property, plant & equipment 47,321 34,518 Intangibles 359,312 167,108 Other — 2,243 Total deferred income tax liabilities 406,633 203,869 Net deferred income tax liability $ (241,520 ) $ (66,806 ) A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2016 , the valuation allowance for certain foreign carryforwards was $21.4 million primarily in Brazil, China and South Africa. Net operating loss carry-forwards in the amount of $59.4 million expire in various periods from December 31, 2017 to December 31, 2036 . As of December 31, 2016 , the liability for income taxes associated with unrecognized tax benefits was $8.4 million , of which $4.2 million , if recognized, would favorably affect the Company’s effective income tax rate. As of December 31, 2015 , the liability for income taxes associated with unrecognized tax benefits was $10.6 million , of which $4.3 million , if recognized, would favorably affect the Company’s effective tax rate. A reconciliation of the beginning and ending amount of the liability for income taxes associated with unrecognized tax benefits follows: In thousands 2016 2015 2014 Gross liability for unrecognized tax benefits at beginning of year $ 10,557 $ 12,596 $ 10,531 Gross increases - unrecognized tax benefits in prior periods 6 — 30 Gross increases - current period unrecognized tax benefits — 1,682 2,756 Gross decreases - unrecognized tax benefits in prior periods — — (463 ) Gross decreases - audit settlement during year — (3,027 ) (77 ) Gross decreases - expiration of audit statute of limitations (2,140 ) (694 ) (181 ) Gross liability for unrecognized tax benefits at end of year $ 8,423 $ 10,557 $ 12,596 The Company includes interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2016 , the total interest and penalties accrued was approximately $0.8 million and $0.3 million , respectively. As of December 31, 2015 , the total interest and penalties accrued was approximately $2.0 million and $0.2 million , respectively. With limited exception, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for years before 2012. At this time, the Company believes that it is reasonably possible that unrecognized tax benefits of approximately $3.3 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS As of December 31, 2016 , the Company maintains employee stock-based compensation plans for stock options, restricted stock, and incentive stock units as governed by the 2011 Stock Incentive Compensation Plan (the “2011 Plan”) and the 2000 Stock Incentive Plan, as amended (the “2000 Plan”). The 2011 Plan has a 10 year term through March 27, 2021 and as of December 31, 2016 the number of shares available for future grants under the 2011 Plan was 2,469,849 shares, which includes remaining shares to grant under the 2000 Plan. The 2011 Plan was approved by stockholders of Wabtec on May 11, 2011. The Company also maintains a 1995 Non-Employee Directors’ Fee and Stock Option Plan (“the Directors Plan”). The Directors Plan, as amended, authorizes a total of 1,000,000 shares of Common Stock to be issued. Under the Directors Plan options issued become exercisable over a three -year vesting period and expire ten years from the date of grant and restricted stock issued under the plan vests one year from the date of grant. As compensation for directors’ fees for the years ended December 31, 2016 , 2015 and 2014 , the Company issued a total of 16,972 , 11,256 and 12,704 shares of restricted stock to non-employee directors. The total number of shares issued under the plan as of December 31, 2016 was 864,692 shares. No units may be made under the Directors Plan subsequent to October 31, 2016 . Stock-based compensation expense for all of the plans was $20.8 million , $26.0 million and $26.1 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. The Company recognized associated tax benefits related to the stock-based compensation plans of $14.9 million , $15.3 million and $7.6 million for the respective periods. Included in the stock-based compensation expense for 2016 above is $1.7 million of expense related to stock options, $6.0 million related to non-vested restricted stock, $3.2 million related to restricted stock units, $8.5 million related to incentive stock units and $1.4 million related to units issued for Directors’ fees. At December 31, 2016 , unamortized compensation expense related to those stock options, non-vested restricted shares and incentive stock units expected to vest totaled $25.8 million and will be recognized over a weighted average period of 1.1 years . Stock Options Stock options are granted to eligible employees and directors at the fair market value, which is the average of the high and low Wabtec stock price on the date of grant. Under the 2011 Plan and the 2000 Plan, options become exercisable over a four years vesting period and expire 10 years from the date of grant. The following table summarizes the Company’s stock option activity and related information for the 2011 Plan, the 2000 Plan and Directors Plan for the years ended December 31: Options Weighted Weighted Average Aggregate Outstanding at December 31, 2013 1,232,862 $ 24.36 6.1 $ 61,530 Granted 81,552 73.20 1,116 Exercised (163,786 ) 20.37 (10,895 ) Canceled (3,070 ) 52.73 (105 ) Outstanding at December 31, 2014 1,147,558 $ 28.33 5.5 $ 67,205 Granted 84,675 87.35 1,375 Exercised (124,156 ) 26.70 (5,516 ) Canceled (10,754 ) 65.22 (64 ) Outstanding at December 31, 2015 1,097,323 $ 32.70 4.8 $ 42,154 Granted 94,115 61.39 2,035 Exercised (83,790 ) 25.58 (4,813 ) Canceled (8,825 ) 71.47 (102 ) Outstanding at December 31, 2016 1,098,823 $ 35.39 4.3 $ 52,332 Exercisable at December 31, 2016 885,442 $ 27.32 3.5 $ 49,321 Options outstanding at December 31, 2016 were as follows: Number of Weighted Weighted Number of Weighted Average Range of exercise prices Outstanding Outstanding Life Exercisable Exercisable Under $15.00 198,000 $ 14.50 2.1 198,000 $ 14.50 15.00 - 23.00 310,149 18.29 1.9 310,149 18.29 23.00 - 30.00 145,779 28.74 3.8 145,779 28.74 30.00 - 38.00 105,924 35.25 5.1 105,924 35.25 Over 38.00 338,971 66.16 7.7 125,590 61.48 1,098,823 $ 35.39 885,442 $ 27.32 The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions: For the year ended December 31, 2016 2015 2014 Dividend yield 0.26 % 0.14 % 0.11 % Risk-free interest rate 1.5 % 1.8 % 2.2 % Stock price volatility 26.9 % 27.3 % 33.0 % Expected life (years) 5.0 5.0 5.0 Weighted average fair value of options granted during the year $ 14.96 $ 24.41 $ 22.82 The dividend yield is based on the Company’s dividend rate and the current market price of the underlying common stock at the date of grant. Expected life in years is determined from historical stock option exercise data. Expected volatility is based on the historical volatility of the Company’s stock. The risk-free interest rate is based on the 7 years U.S. Treasury bond rates for the expected life of the option. Restricted Stock and Incentive Stock Beginning in 2006 the Company adopted a restricted stock program. As provided for under the 2011 and 2000 Plans, eligible employees are granted restricted stock that generally vests over four years from the date of grant. Under the Directors Plan, restricted stock units vest one year from the date of grant. In addition, the Company has issued incentive stock units to eligible employees that vest upon attainment of certain cumulative three -year performance goals. Based on the Company’s performance for each three year period then ended, the incentive stock units can vest and be awarded ranging from 0% to 200% of the initial incentive stock units granted. The incentive stock units included in the table below represent the number of shares that are expected to vest based on the Company’s estimate for meeting those established performance targets. As of December 31, 2016 , the Company estimates that it will achieve 117% , 92% and 95% for the incentive stock units expected to vest based on performance for the three year periods ending December 31, 2016 , 2017 , and 2018 , respectively, and has recorded incentive compensation expense accordingly. If our estimate of the number of these stock units expected to vest changes in a future accounting period, cumulative compensation expense could increase or decrease and will be recognized in the current period for the elapsed portion of the vesting period and would change future expense for the remaining vesting period. Compensation expense for the non-vested restricted stock and incentive stock units is based on the closing price of the Company’s common stock on the date of grant and recognized over the applicable vesting period. The following table summarizes the restricted stock activity and related information for the 2011 Plan, the 2000 Plan, and Directors Plan, and incentive stock units activity and related information for the 2011 Plan and the 2000 Plan with related information for the years ended December 31: Restricted Incentive Weighted Outstanding at December 31, 2013 510,129 1,043,594 $ 35.27 Granted 150,886 140,240 73.68 Vested (218,502 ) (458,536 ) 29.83 Adjustment for incentive stock awards expected to vest — 74,680 47.56 Canceled (3,970 ) (8,370 ) 48.50 Outstanding at December 31, 2014 438,543 791,608 $ 47.97 Granted 113,945 126,050 87.90 Vested (182,776 ) (433,932 ) 37.76 Adjustment for incentive stock awards expected to vest — 65,666 57.57 Canceled (12,827 ) (7,754 ) 67.05 Outstanding at December 31, 2015 356,885 541,638 $ 65.89 Granted 212,600 167,850 66.03 Vested (159,975 ) (236,591 ) 51.80 Adjustment for incentive stock awards expected to vest — (38,164 ) 74.42 Canceled (13,215 ) (9,983 ) 71.84 Outstanding at December 31, 2016 396,295 424,750 $ 72.18

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING Foreign Currency Hedging The Company uses forward contracts to mitigate its foreign currency exchange rate exposure due to forecasted sales of finished goods and future settlement of foreign currency denominated assets and liabilities. Derivatives used to hedge forecasted transactions and specific cash flows associated with foreign currency denominated financial assets and liabilities that meet the criteria for hedge accounting are designated as cash flow hedges. The effective portion of gains and losses is deferred as a component of accumulated other comprehensive income and is recognized in earnings at the time the hedged item affects earnings, in the same line item as the underlying hedged item. The contracts are scheduled to mature within two years. For the twelve months ended December 31, 2016 , the amount reclassified into income was $0.6 million . Other Activities The Company enters into certain derivative contracts in accordance with its risk management strategy that do not meet the criteria for hedge accounting but which have the impact of largely mitigating foreign currency exposure. These foreign exchange contracts are accounted for on a full mark to market basis through earnings, with gains and losses recorded as a component of other expense, net. The net unrealized gain related to these contracts was $0.2 million for the twelve months ended December 31, 2016 . The notional amount and fair value of foreign exchange contracts that did not meet the criteria for hedge accounting at December 31, 2016 was not material. These contracts are scheduled to mature within one year. The following table summarizes the gross notional amounts and fair values of the designated and non-designated hedged discussed in the above sections: In millions Designated Non-Designated Total Gross notional amount $ 911.0 $ 490.0 $ 1,401.0 Fair Value: Other current assets 1.1 0.4 1.5 Other current liabilities (0.5 ) (0.2 ) (0.7 ) Total $ 0.6 $ 0.2 $ 0.8 Interest Rate Hedging The Company uses interest rate swaps to manage interest rate exposures. The Company is exposed to interest rate volatility with regard to existing floating rate debt. Primary exposure includes the London Interbank Offered Rates (LIBOR). Derivatives used to hedge risk associated with changes in the fair value of certain variable-rate debt are primarily designated as fair value hedges. Consequently, changes in the fair value of these derivatives, along with changes in the fair value of debt obligations are recognized in current period earnings. See long-term debt footnote fair value measurement footnote for further information on current interest rate swaps. As of December 31, 2016 , the Company has recorded a current liability of $3.9 million and an accumulated other comprehensive loss of $2.3 million , net of tax, related to these agreements .

FAIR VALUE MEASUREMENT AND FAIR

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS ASC 820 “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value and explains the related disclosure requirements. ASC 820 indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model. Valuation Hierarchy. ASC 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the liabilities carried at fair value measured on a recurring basis as of December 31, 2016 , which are included in other current liabilities on the Consolidated Balance sheet: Fair Value Measurements at December 31, 2016 Using Total Carrying Quoted Prices in Significant Other Significant In thousands 2016 (Level 1) (Level 2) (Level 3) Interest rate swap agreements 3,888 — 3,888 — Total $ 3,888 $ — $ 3,888 $ — The following table provides the liabilities carried at fair value measured on a recurring basis as of December 31, 2015 , which are included in other current liabilities on the Consolidated Balance sheet: Fair Value Measurements at December 31, 2015 Using Total Carrying Quoted Prices in Significant Other Significant In thousands 2015 (Level 1) (Level 2) (Level 3) Interest rate swap agreements 4,474 — 4,474 — Total $ 4,474 $ — $ 4,474 $ — To reduce the impact of interest rate changes on a portion of its variable-rate debt, the Company entered into interest rate swaps which effectively converted a portion of the debt from variable to fixed-rate borrowings during the term of the swap contracts. For certain derivative contracts whose fair values are based upon trades in liquid markets, such as interest rate swaps, valuation model inputs can generally be verified and valuation techniques do not involve significant management judgment. The fair values of such financial instruments are generally classified within Level 2 of the fair value hierarchy. As a result of our global operating activities the Company is exposed to market risks from changes in foreign currency exchange rates, which may adversely affect our operating results and financial position. When deemed appropriate, the Company minimizes these risks through entering into foreign currency forward contracts. The foreign currency forward contracts are valued using broker quotations, or market transactions in either the listed or over-the counter markets. As such, these derivative instruments are classified within level 2. The Company’s cash and cash equivalents are highly liquid investments purchased with an original maturity of three months or less and are considered Level 1 on the fair value valuation hierarchy. The fair value of cash and cash equivalents approximated the carrying value at December 31, 2016 and December 31, 2015 . The Company’s defined benefit pension plan assets consist primarily of equity security funds, debt security funds and temporary cash and cash equivalent investments. Generally, all plan assets are considered Level 2 based on the fair value valuation hierarchy. These investments are comprised of a number of investment funds that invest in a diverse portfolio of assets including equity securities, corporate and governmental bonds, and money markets. Trusts are valued at the net asset value (“NAV”) as determined by their custodian. NAV represents the accumulation of the unadjusted quoted close prices on the reporting date for the underlying investments divided by the total shares outstanding at the reporting dates. The 2013 and 2016 Notes are considered Level 2 based on the fair value valuation hierarchy. The estimated fair values and related carrying values of the Company’s financial instruments are as follows: December 31, 2016 December 31, 2015 Carry Fair Carry Fair In thousands Value Value Value Value Interest rate swap agreements $ 3,888 $ 3,888 $ 4,474 $ 4,474 4.375% Senior Notes 248,310 260,265 248,053 254,075 3.45% Senior Notes 747,474 719,273 — — The fair value of the Company’s interest rate swap agreements and the 2013 and 2016 Notes were based on dealer quotes and represent the estimated amount the Company would pay to the counterparty to terminate the agreement.

COMMITMENTS AND CONTINGENCIES

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company is subject to a variety of environmental laws and regulations governing discharges to air and water, the handling, storage and disposal of hazardous or solid waste materials and the remediation of contamination associated with releases of hazardous substances. The Company believes its operations currently comply in all material respects with all of the various environmental laws and regulations applicable to our business; however, there can be no assurance that environmental requirements will not change in the future or that we will not incur significant costs to comply with such requirements. Under terms of the purchase agreement and related documents for the 1990 Acquisition, American Standard, Inc., now known as Trane (“Trane”), has indemnified the Company for certain items including, among other things, certain environmental claims the Company asserted prior to 2000. If Trane was unable to honor or meet these indemnifications, the Company would be responsible for such items. In the opinion of Management, Trane currently has the ability to meet its indemnification obligations. Claims have been filed against the Company and certain of its affiliates in various jurisdictions across the United States by persons alleging bodily injury as a result of exposure to asbestos-containing products. Most of these claims have been made against our wholly owned subsidiary, Railroad Friction Products Corporation (“RFPC”), and are based on a product sold by RFPC prior to the time that the Company acquired any interest in RFPC. Most of these claims, including all of the RFPC claims, are submitted to insurance carriers for defense and indemnity or to non-affiliated companies that retain the liabilities for the asbestos-containing products at issue. We cannot, however, assure that all these claims will be fully covered by insurance or that the indemnitors or insurers will remain financially viable. Our ultimate legal and financial liability with respect to these claims, as is the case with other pending litigation, cannot be estimated. It is management’s belief that the potential range of loss for asbestos-related bodily injury cases is not reasonably determinable at present due to a variety of factors, including: (1) the asbestos case settlement history of the Company’s wholly owned subsidiary, RFPC; (2) the unpredictable nature of personal injury litigation in general; and (3) the uncertainty of asbestos litigation in particular. Despite this uncertainty, and although the results of the Company’s operations and cash flows for any given period could be adversely affected by asbestos-related lawsuits, Management believes that the final resolution of the Company’s asbestos-related cases will not be material to the Company’s overall financial position, results of operations and cash flows. In general, this belief is based upon: (1) Wabtec’s and RFPC’s history of settlements and dismissals of asbestos-related cases to date; (2) the inability of many plaintiffs to establish any exposure or causal relationship to RFPC’s product; and (3) the inability of many plaintiffs to demonstrate any identifiable injury or compensable loss. More specifically, as to RFPC, management’s belief that any losses due to asbestos-related cases would not be material is also based on the fact that RFPC owns insurance which provides coverage for asbestos-related bodily injury claims. To date, RFPC’s insurers have provided RFPC with defense and indemnity in these actions. The overall number of new claims being filed against RFPC has dropped significantly in recent years; however, these new claims, and all previously filed claims, may take a significant period of time to resolve. As to Wabtec and its divisions, Management’s belief that asbestos-related cases will not have a material impact is also based on its position that it has no legal liability for asbestos-related bodily injury claims, and that the former owners of Wabtec’s assets retained asbestos liabilities for the products at issue. To date, Wabtec has been able to successfully defend itself on this basis, including two arbitration decisions and a judicial opinion, all of which confirmed Wabtec’s position that it did not assume any asbestos liabilities from the former owners of certain Wabtec assets. Although Wabtec has incurred defense and administrative costs in connection with asbestos bodily injury actions, these costs have not been material, and the Company has no information that would suggest these costs would become material in the foreseeable future. On April 21, 2016, Siemens Industry, Inc. filed a lawsuit against the Company in federal district court in Delaware alleging that the Company has infringed seven patents owned by Siemens, all of which relate to Positive Train Control technology. On November 2, 2016, Siemens amended its complaint to add six additional patents they also claim are infringed by the Company’s Positive Train Control Products. The Company has filed Answers, and asserted counterclaims, in response to Siemens’ complaints. The case is still in the preliminary stages, but the Company has begun filing for Inter-Parties Review proceedings before the U.S. Patent & Trademark Office seeking to invalidate the Siemens patents. Wabtec believes the claims are without merit and is vigorously defending itself. From time to time the Company is involved in litigation relating to claims arising out of its operations in the ordinary course of business. As of the date hereof, the Company is involved in no litigation that the Company believes will have a material adverse effect on its financial condition, results of operations or liquidity.

The key factors used to identify these reportable segments are the organization and alignment of the Company’s internal operations, the nature of the products and services, and customer type. The business segments are: Freight Segment primarily manufactures and services components for new and existing freight cars and locomotives, builds new switcher locomotives, rebuilds freight locomotives, supplies railway electronics, positive train control equipment, signal design and engineering services, and provides related heat exchange and cooling systems. Customers include large, publicly traded railroads, leasing companies, manufacturers of original equipment such as locomotives and freight cars, and utilities. Transit Segment primarily manufactures and services components for new and existing passenger transit vehicles, typically regional trains, high speed trains, subway cars, light-rail vehicles and buses, builds new commuter locomotives, refurbishes subway cars, provides heating, ventilation, and air conditioning equipment, and doors for buses and subways. Customers include public transit authorities and municipalities, leasing companies, and manufacturers of subway cars and buses around the world. The Company evaluates its business segments’ operating results based on income from operations. Intersegment sales are accounted for at prices that are generally established by reference to similar transactions with unaffiliated customers. Corporate activities include general corporate expenses, elimination of intersegment transactions, interest income and expense and other unallocated charges. Since certain administrative and other operating expenses and other items have not been allocated to business segments, the results in the following tables are not necessarily a measure computed in accordance with generally accepted accounting principles and may not be comparable to other companies.

SUMMARY OF SIGNIFICANT ACCOUN35

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts of the Company and all subsidiaries that it controls. For consolidated subsidiaries in which the Company's ownership is less than 100%, the outside shareholders' interests are shown as noncontrolling interests. These statements have been prepared in accordance with U.S. generally accepted accounting principles. Sales between subsidiaries are billed at prices consistent with sales to third parties and are eliminated in consolidation.
Cash Equivalents	Cash equivalents are highly liquid investments purchased with an original maturity of three months or less.
Allowance for Doubtful Accounts	The allowance for doubtful accounts receivable reflects our best estimate of probable losses inherent in our receivable portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence.
Inventories	Inventories are stated at the lower of cost or market. Cost is determined under the first-in, first-out (FIFO) method. Inventory costs include material, labor and overhead.
Property, Plant and Equipment	Property, plant and equipment additions are stated at cost. Expenditures for renewals and improvements are capitalized. Expenditures for ordinary maintenance and repairs are expensed as incurred. The Company computes book depreciation principally on the straight-line method. Accelerated depreciation methods are utilized for income tax purposes.
Leasing Arrangements	The Company conducts a portion of its operations from leased facilities and finances certain equipment purchases through lease agreements. In those cases in which the lease term approximates the useful life of the leased asset or the lease meets certain other prerequisites, the leasing arrangement is classified as a capital lease. The remaining arrangements are treated as operating leases.
Goodwill and Intangible Assets	Goodwill and other intangible assets with indefinite lives are not amortized. Other intangibles (with definite lives) are amortized on a straight-line basis over their estimated economic lives. Amortizable intangible assets are reviewed for impairment when indicators of impairment are present. The Company tests goodwill and indefinite-lived intangible assets for impairment at the reporting unit level and at least annually. The Company performs its annual impairment test during the fourth quarter after the annual forecasting process is completed, and also tests for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Periodically, Management of the Company assesses whether or not an indicator of impairment is present that would necessitate an impairment analysis be performed. For 2016, the Company opted to proceed directly to the two-step quantitative impairment test for all reporting units with goodwill. In the first step of the quantitative assessment, our assets and liabilities, including existing goodwill and other intangible assets, are assigned to the identified reporting units to determine the carrying value of the reporting units. The income approach and the market approach are weighted at 45% and 55%, respectively, in arriving at fair value, which the Company has applied consistently. The discounted cash flow model requires several assumptions including future sales growth, EBIT (earnings before interest and taxes) margins and capital expenditures for the reporting units. The discounted cash flow model also requires the use of a discount rate and a terminal revenue growth rate (the revenue growth rate for the period beyond the years forecasted by the reporting units), as well as projections of future operating margins. The market approach requires several assumptions including EBITDA (earnings before interest, taxes, depreciation and amortization) multiples for comparable companies that operate in the same markets as the Company’s reporting units. The estimated fair value of all reporting units was substantially in excess of its respective carrying value, which resulted in a conclusion that no impairment existed. Additionally, the Company proceeded directly to the quantitative impairment test for some trade names with indefinite lives. The fair value of all trade names subject to the quantitative impairment test exceeded its respective carrying value, resulting in a conclusion that no impairment existed. For trade names not subject to the quantitative testing, the Company opted to perform a qualitative trade name impairment assessment and determined from the qualitative assessment that it was not more likely than not that the estimated fair values of the trade names were less than their carrying values; therefore, no further analysis was required. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a trade name is less than its carrying amount, we assess relevant events and circumstances that may impact the fair value and the carrying amount of the trade name. The identification of relevant events and circumstances and how these may impact a trade name’s fair value or carrying amount involve significant judgments and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact.
Warranty Costs	Warranty costs are accrued based on Management’s estimates of repair or upgrade costs per unit and historical experience.
Income Taxes	Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws. The provision for income taxes includes federal, state and foreign income taxes.
Stock-Based Compensation	The Company recognizes compensation expense for stock-based compensation based on the grant date fair value amortized ratably over the requisite service period following the date of grant.
Financial Derivatives and Hedging Activities	The Company has entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. Foreign currency forward contracts are agreements with a counterparty to exchange two distinct currencies at a set exchange rate for delivery on a set date at some point in the future. There is no exchange of funds until the delivery date.
Foreign Currency Translation	Assets and liabilities of foreign subsidiaries, except for the Company’s Mexican operations whose functional currency is the U.S. Dollar, are translated at the rate of exchange in effect on the balance sheet date while income and expenses are translated at the average rates of exchange prevailing during the period. Foreign currency gains and losses resulting from transactions, and the translation of financial statements are recorded in the Company’s consolidated financial statements based upon the provisions of Accounting Standards Codification (“ASC”) 830, “Foreign Currency Matters.” The effects of currency exchange rate changes on intercompany transactions and balances of a long-term investment nature are accumulated and carried as a component of accumulated other comprehensive loss. The effects of currency exchange rate changes on intercompany transactions that are denominated in a currency other than an entity’s functional currency are charged or credited to earnings.
Noncontrolling Interests	In accordance with ASC 810, the Company has classified noncontrolling interests as equity on our condensed consolidated balance sheets as of December 31, 2016 and 2015 . Net income attributable to noncontrolling interests for the year ended December 31, 2016 was $8.5 million . Net income attributable to noncontrolling interests for the years ended December 31, 2015 and 2014 was not material.
Revenue Recognition	Revenue is recognized in accordance with ASC 605 “Revenue Recognition,” The Company recognizes revenue when the following criteria are met: 1) persuasive evidence of an arrangement exists; 2) delivery has occurred; 3) an established sales price has been set with the customer; 4) collection of the sale revenue from the customer is reasonably assured; and 5) no contingencies exist. Delivery is considered to have occurred when the customer assumes the risk and rewards of ownership. The Company estimates and records provisions for quantity rebates and sales returns and allowances as an offset to revenue in the same period the related revenue is recognized, based upon its experience. These items are included as a reduction in deriving net sales. In general, the Company recognizes revenues on long-term contracts based on the percentage of completion method of accounting. The units-of-delivery method or other input-based or output-based measures, as appropriate, are used to measure the progress toward completion of individual contracts. Contract revenues and cost estimates are reviewed and revised quarterly at a minimum and adjustments are reflected in the accounting period as such amounts are determined. Provisions are made currently for estimated losses on uncompleted contracts. Unbilled accounts receivables were $274.9 million and $103.8 million , customer deposits were $256.6 million and $106.1 million , and provisions for loss contracts were $60.5 million and $11.8 million at December 31, 2016 and 2015 , respectively. Certain pre-production costs relating to long-term production and supply contracts have been deferred and will be recognized over the life of the contracts. Deferred pre-production costs were $29.4 million and $30.3 million at December 31, 2016 and 2015 , respectively.
Significant Customers and Concentrations of Credit Risk	The Company’s trade receivables are from rail and transit industry original equipment manufacturers, Class I railroads, railroad carriers and commercial companies that utilize rail cars in their operations, such as utility and chemical companies. No one customer accounted for more than 10% of the Company’s consolidated net sales in 2016 , 2015 or 2014 .
Shipping and Handling Fees and Costs	All fees billed to the customer for shipping and handling are classified as a component of net revenues. All costs associated with shipping and handling are classified as a component of cost of sales.
Research and Development	Research and development costs are charged to expense as incurred. For the years ended December 31, 2016 , 2015 and 2014 , the Company incurred costs of approximately $71.4 million , $71.2 million , and $61.9 million , respectively.
Employees	As of December 31, 2016 , approximately 35% of the Company’s workforce was covered by collective bargaining agreements. These agreements are generally effective from 2017 through 2019. Agreements expiring in 2017 cover approximately 20% of the Company’s workforce.
Earnings Per Share	Basic and diluted earnings per common share is computed in accordance with ASC 260 “Earnings Per Share.” Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and included in the computation of earnings per share pursuant to the two-class method included in ASC 260-10-55. (See Note 11 “Earnings Per Share” included herein)
Reclassifications	Certain prior year amounts have been reclassified, where necessary, to conform to the current year presentation. Refer to Recently Adopted Accounting Pronouncements below.
Use of Estimates	The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates. On an ongoing basis, Management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.
Recently Issued Accounting Pronouncements	In November 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-18 "Statement of Cash Flows (Topic 230): Restricted Cash". The amendments in this update require a statement of cash flows explain the change during the period in total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The ASU is effective for public companies in the fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. The ASU simplifies several aspects for the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The ASU is effective for public companies in the fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. In accordance with this update, the Company will recognize all excess tax benefits and tax deficiencies from share-based payment awards as income tax expense or benefit in the income statement (currently excess tax benefits are recognized in additional paid-in capital on the consolidated balance sheet). Additionally, upon adoption of this update the Company will classify excess income tax benefits from exercise of stock options as an operating activity on the consolidated statement of cash flows (currently income tax benefits from the exercise of stock options are classified as a financing activity). In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 814)" which requires lessees to recognize a right of use asset and lease liability on the balance sheet for all leases with terms longer than 12 months. For leases with terms less than 12 months, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize a right of use asset and lease liability. The ASU is effective for public companies in the fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-9, “Revenue from Contract with Customers.” The ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Board voted to propose that the standard would take effect for reporting periods beginning after December 15, 2017 and that early adoption would be allowed as of the original effective date. The impact of adopting the new standard on 2016 and 2015 net sales and operating income is not expected to be material. The Company also does not expect a material impact to the consolidated balance sheet. The impact to results is not anticipated to be material because the analysis of the Company's current contracts under the new revenue recognition standard supports the recognition of revenue over time under the cost-to-cost method for the majority of our contracts, which is consistent with our current revenue recognition model. The Company plans to adopt this accounting standard update using the modified retrospective method, with the cumulative effect of initially applying this update recognized in the first reporting period of 2018. The Company is in the process of drafting an updated accounting policy, evaluating new disclosure requirements and identifying and implementing appropriate changes to its business processes, systems and controls to support recognition and disclosure under the new guidance. Recently Adopted Accounting Pronouncements In November 2015, the FASB issued ASU No. 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes" which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities to be classified as noncurrent on the balance sheet. The Company elected to early adopt this ASU as of December 31, 2016; therefore, all deferred income tax assets and liabilities are classified in the noncurrent deferred income taxes line-items on the consolidated balance sheet. Additionally, the Company elected to update the December 31, 2015 balance sheet for comparative purposes. As a result, $71.7 million of current deferred income tax assets (previously reported in current deferred income taxes) and $0.8 million of current deferred income tax liabilities (previously reported in other accrued liabilities) were reclassified to the other noncurrent assets and noncurrent deferred tax line items, respectively, on the December 31, 2015 consolidated balance sheet. In September 2015, the FASB issued ASU No. 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments" which require an acquirer 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 effect on earnings of changes in depreciation, amortization or other income effects as a result of the change to the provisional amounts are to be recorded in the same period's financial statements and calculated as if the accounting had been completed at the acquisition date. The Company adopted this ASU on January 1, 2016. The adoption of this ASU did not have a material impact on the consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-3, “Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-3”) which changes the presentation of debt issuance costs in financial statements to present such costs as a direct deduction from the related debt liability rather than as an asset. ASU 2015-3 became effective for public companies during interim and annual reporting periods beginning after December 15, 2015. The Company retrospectively adopted this ASU on January 1, 2016. The adoption of this ASU did not have a material impact on the consolidated financial statements.
