4. ACQUISITIONS

Faiveley Transport

On November 30, 2016, the Company acquired majority ownership of Faiveley Transport S.A. (“Faiveley Transport”) under the terms of a Share Purchase Agreement (“Share Purchase 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 value-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 was structured as a step acquisition as follows:

•

On November 30, 2016, the Company acquired majority ownership of Faiveley Transport, after completing the purchase of the Faiveley family’s ownership interest under the terms of the Share Purchase Agreement, which directed the Company to pay €100 per share of Faiveley Transport, payable between 25% and 45% in cash at the election of those shareholders and the remainder payable in Wabtec stock. The Faiveley family’s ownership interest acquired by the Company represented approximately 51% of outstanding share capital and approximately 49% of the outstanding voting shares of Faiveley Transport. Upon completion of the share purchase under the Share Purchase Agreement, Wabtec commenced a tender offer for the remaining publicly traded Faiveley Transport shares. The public shareholders had the option to elect to receive €100 per share in cash or 1.1538 shares of Wabtec common stock per share of Faiveley Transport. The common stock portion of the consideration was subject to a cap on issuance of Wabtec common shares that was equivalent to the rates of cash and stock elected by the 51% owners.

•

On February 3, 2017, the initial cash tender offer was closed, which resulted in the Company acquiring approximately 27% of additional outstanding share capital and voting rights of Faiveley Transport for approximately $411.8 million in cash and $25.2 million in Wabtec stock. After the initial cash tender offer, the Company owned approximately 78% of outstanding share capital and 76% of voting rights.

•

On March 6, 2017, the final cash tender offer was closed, which resulted in the Company acquiring approximately 21% of additional outstanding share capital and 22% of additional outstanding voting rights of Faiveley Transport for approximately $303.2 million in cash and $0.3 million in Wabtec stock. After the final cash tender offer, the Company owned approximately 99% of the share capital and 98% of the voting rights of Faiveley Transport.


•	On March 21, 2017, a mandatory squeeze-out procedure was finalized, which resulted in the Company acquiring the Faiveley Transport shares not tendered in the offers for approximately $17.5 million in cash. This resulted in the Company owning 100% of the share capital and voting rights of Faiveley Transport.

As of November 30, 2016, the date the Company acquired 51% of the share capital and 49% of the voting interest in Faiveley Transport, Faiveley Transport was consolidated under the variable interest entity model as the Company concluded that it was the primary beneficiary of Faiveley Transport as it then possessed the power to direct the activities of Faiveley Transport that most significantly impact its economic performance and it then possessed the obligation and right to absorb losses and benefits from Faiveley Transport.

The purchase price paid for 100% ownership of Faiveley Transport was $1,507.0 million. The $744.7 million included as deposits in escrow on the consolidated balance sheet at December 31, 2016 was cash designated for use as consideration for the tender offers.

The fair values of the assets acquired and liabilities assumed were 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 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 acquisition of the noncontrolling interest during the three months ended March 31, 2017 resulted in a $8.9 million increase to additional paid-in capital on the consolidated balance sheet which represents the difference in consideration paid to acquire the noncontrolling interest and the carrying value of noncontrolling interest at acquisition.

The following table summarizes the final fair values of the Faiveley Transport assets acquired and liabilities assumed:



In thousands
Assets acquired
Cash and cash equivalents	$	178,318
Accounts receivable		439,631
Inventories		205,649

Debt		409,899
Other noncurrent liabilities		335,039
Total liabilities assumed		1,564,431
Net assets acquired	$	1,506,815

During the twelve months ended December 31, 2017, the estimated fair values for customer relationships and current liabilities were adjusted by $21.8 million and $65.3 million, respectively, for changes to initial estimates based on information that existed at the date of acquisition. Additionally, the estimated fair values for accounts receivable and current liabilities were adjusted by $2.8 million and $36.2 million, respectively, to correct errors in the preliminary estimated fair values of the Faiveley Transport assets acquired and liabilities assumed. Other noncurrent assets were adjusted by $30.0 millionto record the deferred tax impact of these adjustments. As a result of these adjustments and other immaterial adjustments related to changes to initial estimates based on information that existed at the date of acquisition, goodwill increased by $74.1 million. Accounts receivable and current liabilities were adjusted by $64.3 million to correct an error in the preliminary estimated fair values of Faiveley Transport assets and liabilities assumed related to a factoring arrangement with recourse.

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, the Company expects to achieve as a result of the acquisition. Purchased goodwill is not deductible for tax purposes. The goodwill allocated to the Freight segment is $72.0 million and the goodwill allocated to the Transit segment is $1,190.4 million.

2018 Refinancing Credit Agreement

On June 8, 2018, the Company entered into a credit agreement (the “2018 Refinancing Credit Agreement”), which replaced the Company’s then-existing “2016 Refinancing Credit Agreement.” As part of the 2018 Refinancing Credit Agreement, the Company entered into (i) a $1.2 billion revolving credit facility (the “Revolving Credit Facility”), which replaced the Company’s revolving credit facility under the 2016 Refinancing Credit Agreement, and includes a letter of credit sub-facility of up to $450.0 million and a swing line sub-facility of $75.0 million, (ii) a $350.0 million term loan (the “Refinancing Term Loan”), which refinanced the term loan under the 2016 Refinancing Credit Agreement, and (iii) a new $400.0 million delayed draw term loan (the “Delayed Draw Term Loan”). The 2018 Refinancing Credit Agreement also provided for a bridge loan facility (the “Bridge Loan Facility”) in an amount not to exceed $2.5 billion, such facility to become effective at the Company’s request. Commitments in respect of the Bridge Loan Facility were terminated upon the issuance and sale of the Senior Notes on September 14, 2018. In addition, the 2018 Refinancing Credit Agreement contains an uncommitted accordion feature allowing the Company to request, in an aggregate amount not to exceed $600.0 million, increases to the borrowing commitments under the Revolving Credit Facility or a new incremental term loan commitment. At September 30, 2018, the Company had available bank borrowing capacity, net of $29.7 million of letters of credit, of approximately $1,170.3 million subject to certain financial covenant restrictions.

The Revolving Credit Facility matures on June 8, 2023 and is unsecured. The Refinancing Term Loan matures on June 8, 2021 and is unsecured. The Delayed Draw Term Loan matures on the third anniversary of the date on which it is borrowed and is unsecured. The applicable interest rate for borrowings under the 2018 Refinancing Credit Agreement includes interest rate spreads based on the lower of the pricing corresponding to (i) the Company’s ratio of total debt (less unrestricted cash up to $300.0 million) to EBITDA (“Leverage Ratio”) or (ii) the Company’s public rating, in each case that range between 1.000% and 1.875% for LIBOR/CDOR-based borrowings and 0.0% and 0.875% for Alternate Base Rate based borrowings. The obligations of the Company under the 2018 Refinancing Credit Agreement have been guaranteed by certain of the Company’s subsidiaries.

The 2018 Refinancing Credit Agreement contains customary representations and warranties by the Company and its subsidiaries, including customary use of materiality, material adverse effect, and knowledge qualifiers. The Company and its subsidiaries are also subject to (i) customary affirmative covenants that impose certain reporting obligations on the Company and its subsidiaries and (ii) customary negative covenants, including limitations on: indebtedness; liens; restricted payments; fundamental changes; business activities; transactions with affiliates; restrictive agreements; changes in fiscal year; and use of proceeds. In addition, the Company is required to maintain (i) an Interest Coverage ratio at least 3.00 to 1.00 over each period of four consecutive fiscal quarters ending on the last day of a fiscal quarter and (ii) a Leverage Ratio, calculated as of the last day of a fiscal quarter for a period of four consecutive fiscal quarters, of 3.25 to 1.00 or less; provided that, in the event the Company completes the Direct Sale and the Merger or any other material acquisition in which the cash consideration paid exceeds $500.0 million, the maximum Leverage Ratio permitted will be 3.75 to 1.00 at the end of the fiscal quarter in which such acquisition is consummated and each of the three fiscal quarters immediately following such fiscal quarter and 3.50 to 1.00 at the end of each of the fourth and fifth full fiscal quarters after the consummation of such acquisition. The Company is in compliance with the restrictions and covenants of the 2018 Refinancing Credit Agreement and does not expect that these measurements will limit the Company in executing its operating activities.

At September 30, 2018, the weighted average interest rate on the Company’s variable rate debt was 3.49%. 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 was 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 this agreement, 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.

2016 Refinancing Credit Agreement

On June 22, 2016, the Company amended and restated its then existing revolving credit facility with a consortium of commercial banks. The “2016 Refinancing Credit Agreement” provided the Company with a $1.2 billion, five years 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 costs related to the 2016 Refinancing Credit Agreement. The 2016 Refinancing Credit Agreement borrowings bore variable interest rates indexed as described below.

The Term Loan was initially drawn on November 25, 2016. The Company incurred a 10 basis point commitment fee from June 22, 2016 until the initial draw.

Under the 2016 Refinancing Credit Agreement, the Company could 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 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 ranges from 0 to 75 basis points. The Alternate Rate was 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 were dependent on the Company’s consolidated total indebtedness to EBITDA ratios. The initial Base Rate margin was 0 basis points and the Alternate Rate margin was 175 basis points.

Schuldschein Loan, Due 2024

In conjunction with the acquisition of Faiveley Transport, Wabtec acquired $137.2 million of a Schuldschein 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 $125.8 million of the outstanding Schuldshein loan. The remaining balance of $11.6 million as of September 30, 2018 matures on March 5, 2024 and bears a fixed rate of 4.00%.

The Schuldschein loan is senior unsecured and ranks pari passu with all existing and future senior debt and senior to all existing and future subordinated indebtedness of the Company. The Schuldshein 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 incurrence of liens. At September 30, 2018, the Company is in compliance with the undertakings and covenants contained in the loan agreement.

In addition, the 2018 Refinancing Credit Agreement contains an uncommitted accordion feature allowing the Company to request, in an aggregate amount not to exceed $600.0 million, increases to the borrowing commitments under the Revolving Credit Facility or a new incremental term loan commitment.

The Revolving Credit Facility matures on June 8, 2023 and is unsecured. The Refinancing Term Loan matures on June 8, 2021 and is unsecured.

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.

EMPLOYEE BENEFIT PLANS

9. EMPLOYEE BENEFIT PLANS

Defined Benefit Pension Plans

The Company sponsors defined benefit pension plans that cover certain U.S., Canadian, German and United Kingdom employees and which provide benefits of stated amounts for each year of service of the employee.

The Company uses a December 31 measurement date for the plans.

The following tables provide information regarding the Company’s defined benefit pension plans summarized by U.S. and international components.

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 $7.3 million to the international plans during 2018. The company does not expect to contribute to the U.S. plans during 2018.

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.

Pension Plan Assets

The Company has established formal investment policies for the assets associated with our pension plans. 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. (See Note 18 “Fair Value Measurement” included herein). Plan assets by asset category at December 31, 2017 and 2016 are as follows:

	U.S.				International
In thousands	2017		2016		2017		2016

Fair value of plan assets	$	37,432	$	35,802	$	281,602	$	241,283

The U.S. plan has a target asset allocation of 55% equity securities and 45% debt securities. The International plan has a target asset allocation of 30% equity securities, 40% debt securities and 30% in other investments. 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.

The following tables summarize our pension plan assets measured at fair value on a recurring basis by fair value hierarchy level (See Note 18):

The weighted average assumptions in the following table represent the rates used to develop the actuarial present value of the projected benefit obligation for the year listed and also the net periodic benefit cost for the following year. The discount rate is based on settling the pension obligation with high grade, high yield corporate bonds.

	U.S.									International
	2017			2016			2015			2017			2016			2015

As of December 31, 2017, the following table represents the amounts included in other comprehensive loss that are expected to be recognized as components of periodic benefit costs in 2018.

Prior service credit		(1,519	)		(7	)
Net actuarial loss (gain)		1,216			(8	)
	$	(303	)	$	(15	)

The assumed health care cost trend rate for the U.S. plans grades from an initial rate of 6.30% to an ultimate rate of 4.50% by 2027 and for international plans from 6.23% to 4.50% by 2027. 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 2017, 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 2017, and decrease the accumulated post-retirement benefit obligation by less than $0.1 million and $0.3 million, respectively.

Defined Contribution Plans

The Company also participates in certain defined contribution plans and multiemployer pension plans. Costs recognized under these plans are summarized as follows:

	For the year ended December 31,
In thousands	2017		2016		2015
Multi-employer pension and health & welfare plans	$	1,522	$	2,054	$	2,584
401(k) savings and other defined contribution plans		23,209		23,062		21,399
Total	$	24,731	$	25,116	$	23,983

The 401(k) savings plan is a participant directed defined contribution plan that holds shares of the Company’s stock as one of the investment options. At December 31, 2017 and 2016, the plan held on behalf of its participants about 495,274 shares with a market value of $40.3 million, and 551,482 shares with a market value of $45.8 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, 2017 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.

(1)	The Company’s contribution represents more than 5% of the total contributions to the plan.

(2)	The Pension Fund’s board adopted a Funding Improvement Plan on October 21, 2015, continuing the existing plan which increased the weekly pension fund contribution rates by $75 with corresponding decreases to the weekly welfare fund contribution rates until December 31, 2017.

(3)	The number of employees covered by this fund decreased due to the closure of the Bensenville, Illinois facility, which affected the period-to-period comparability of 2016 and 2017 contributions.

(4)	Critical status triggered a 5% surcharge on employer contributions effective June 2012. Effective January 1, 2013, this surcharge increases to 10%. The surcharge ended on October 21, 2015 when the rehabilitation plan commenced.

(b)

The most recent Pension Protection Act Zone Status available for 2017 and 2016 is for plan years that ended in 2016 and 2015, respectively. The zone status is based on information provided to the Company and other participating employers by each plan and is certified by the plan’s actuary. 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.

(c)

The “FIP/RP Status Pending/Implemented” column indicates whether a Funding Improvement Plan, as required under the Code to be adopted by plans in the “yellow” zone, or a Rehabilitation Plan, as required under the Code to be adopted by plans in the “red” zone, is pending or has been implemented as of the end of the plan year that ended in 2017.

(d)	The “Surcharge Imposed” column indicates whether the Company’s contribution rate for 2017 included an amount in addition the contribution rate specified in the applicable collective bargaining agreement, as imposed by a plan in “critical status”, in accordance with the requirements of the Code.

INCOME TAXES

11. 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.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years (the "Transition Tax"), a reduction of the U.S. federal corporate tax rate from 35% to 21%, repeals the Domestic Manufacturing Deduction, a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries, new provisions designed to tax global intangible low-taxed income ("GILTI"), tax certain deductible base erosion payments called base erosion and anti-abuse tax (“BEAT”), and new interest expense limitation provisions.

In relation to the initial analysis of the impact of the all tax law changes at December 31, 2017, the Company recorded a net tax expense of $4.3 million. This included a provisional expense for the U.S tax reform bill of $55.0 million, as well as a net benefit for the revaluation of deferred tax assets and liabilities of $50.7 million.

In the current quarter, the Company has revised its accounting for the income tax effects of the Tax Act. The Company has adjusted the provisional amounts previously recorded in accordance with SEC Staff Accounting Bulletin No. 118. As such, the Company has included the following tax provisions in its financial statements as of September 30, 2018:

Revaluation of deferred tax assets and liabilities: The Tax Act reduces the U.S. federal corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017. In addition, the Tax Act makes certain changes to the depreciation rules and implements new limits on the deductibility of certain executive compensation. The Company evaluated these changes and recorded a provisional benefit to net deferred taxes of $24.6 million at December 31, 2017. As a result of the completion of its 2017 U.S. corporate tax return in the three months ended September 30, 2018, the Company has adjusted its US deferred tax balances which has resulted in a current period benefit of $3.2 million. The Company has revised its calculation of the impact of these changes on its deferred tax balances. As of September 30, 2018, the Company has reviewed its analysis of the impact of the Tax Act on the deductibility of certain executive compensation. As a result, no further adjustments were made as of September 30, 2018.

Transition Tax on unrepatriated foreign earnings: The Transition Tax on unrepatriated foreign earnings is a tax on previously untaxed accumulated and current earnings and profits ("E&P") of the Company's foreign subsidiaries. To determine the amount of the Transition Tax, the Company must determine, among other factors, the amount of post-1986 E&P of its foreign subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. The Company was able to make a reasonable estimate of the Transition Tax and recorded a provisional Transition Tax expense of $51.8 million at December 31, 2017. As of September 30, 2018, the Company has revised its calculation of the Transition Tax which resulted in a benefit of $3.3 million and $13.4 million for the three and nine months ended September 30, 2018.

The Company's accounting for the following impacted areas of the Tax Act is incomplete. However, the Company was able to make reasonable estimates of certain effects and, therefore, has recorded provisional amounts as follows:

Global intangible low taxed income: The Tax Act created a new requirement that certain income (i.e., GILTI) earned by foreign subsidiaries must be included currently in the gross income of the U.S. shareholder. Under U.S. GAAP, the Company is permitted to make an accounting policy election to either treat taxes due on future inclusions in U.S. taxable income related toGILTI as a current-period expense when incurred or to factor such amounts into the Company's measurement of its deferred taxes. The Company has made the election to treat taxes due on future inclusions related to GILTI as current period expense. The Company was able to make reasonable estimates to calculate a provision that is included in the current period expense. The Company will continue to evaluate and update this provision and the application of ASC 740.

The overall effective income tax rate was 16.2% and 17.2% for the three and nine months ended September 30, 2018, respectively, and 15.7% and 23.4% for the three and nine months ended September 30, 2017, respectively. The increase in the effective tax for the three months ended September 30, 2018 is due to a deferred tax net benefit recorded in the prior three month period ended September 30, 2017. The decrease in the effective tax for the nine months ended September 30, 2018 is due to the tax benefits related to the Tax Act as discussed above, a higher earnings mix in lower tax jurisdictions and the release of uncertain tax positions due to the expiration of statutes.

During the current three month period ending September 30, 2018, certain statutes have expired related to uncertain tax positions that were previously recorded resulting in a $2.4 million reduction to the liability for uncertain tax positions, $1.1 million of which favorably affected the Company’s effective tax rate. As of September 30, 2018, the liability for income taxes associated with uncertain tax positions was $4.5 million, of which $3.3 million, if recognized, would favorably affect the Company’s effective tax rate. As of December 31, 2017, the liability for income taxes associated with uncertain tax positions was $6.9 million, of which $4.4 million, if recognized, would favorably affect the Company’s effective tax rate.

The Company includes interest and penalties related to uncertain tax positions in income tax expense. During the current three month period ending September 30, 2018, certain statutes have expired related to uncertain tax positions that were previously recorded. The net reduction in accrued interest expense related to these positions totaled $0.3 million which favorably affected the Company’s effective tax rate. As of September 30, 2018, the total accrued interest and penalties are $0.6 million and $0.1 million, respectively. As of December 31, 2017, the total accrued interest and penalties were $0.7 million and $0.1 million, respectively.

At this time, the Company believes it is reasonably possible that unrecognized tax benefits of approximately $4.5 million may change within the next 12 months due to the expiration of statutory review periods and current examinations. With limited exceptions, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for years before 2014.

10. INCOME TAXES

On December 23, 2017, the French government enacted the Finance Act for 2018 and it was published in the Official Bulletin on December 31, 2017. The Finance act reduced the French corporate tax rate from 28% in 2020 to 25%, enacting an additional 1.5% reduction in each year 2021 and 2022.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code that affect fiscal 2017, including, but not limited to requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years (the “Transition Tax”). The Tax Act also establishes new tax laws that will affect 2018 and later years, including, but not limited to, a reduction of the U.S. federal corporate tax rate from 35% to 21%, repeals the Domestic Manufacturing Deduction, a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries, new provisions designed to tax global intangible low-taxed income (“GILTI”), tax certain deductible base erosion payments called base erosion and anti-abuse tax (“BEAT”), and new interest expense limitation provisions.

In relation to the initial analysis of the impact of the all tax law changes, the Company has recorded a net tax expense of $4.3 million. This includes a provisional expense for the U.S. tax reform bill of $55.0 million, as well as a net benefit for the revaluation of deferred tax assets and liabilities of $50.7 million.

The Company has not completed its accounting for the income tax effects of the Tax Act. Where the Company has been able to make reasonable estimates of the effects for which its analysis is not yet complete, the Company has recorded provisional amounts in accordance with SEC Staff Accounting Bulletin No. 118. Where the Company has not yet been able to make reasonable estimates of the impact of certain elements, the Company has not recorded any amounts related to those elements and has continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect immediately prior to the enactment of the Tax Act.

The Company’s accounting for the following impacted areas of the Tax Act is incomplete. However, the Company was able to make reasonable estimates of certain effects and, therefore, has recorded provisional amounts as follows:

Transition Tax on unrepatriated foreign earnings: The Transition Tax on unrepatriated foreign earnings is a tax on previously untaxed accumulated and current earnings and profits (“E&P”) of the Company’s foreign subsidiaries. To determine the amount of the Transition Tax, the Company must determine, among other factors, the amount of post-1986 E&P of its foreign subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. The Company was able to make a reasonable estimate of the Transition Tax and has recorded a provisional Transition Tax expense of $51.8 million. The Company is continuing to gather additional information to more precisely compute the amount of the Transition Tax to complete its calculation of E&P as well as the final determination of non-U.S. income taxes paid.

The Company’s accounting for the following elements of the Tax Act is incomplete, and it has not yet been able to make reasonable estimates of the effects of these items. Therefore, no provisional amounts were recorded.

Global intangible low taxed income (“GILTI”): The Tax Act creates a new requirement that certain income (i.e., GILTI) earned by foreign subsidiaries must be included currently in the gross income of the U.S. shareholder. Due to the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, the Company is permitted to make an accounting policy election to either treat taxes due on future inclusions in U.S. taxable income related to GILTI as a current-period expense when incurred or to factor such amounts into the Company’s measurement of its deferred taxes. The Company has not yet completed its analysis of the GILTI tax rules and is not yet able to reasonably estimate the effect of this provision of the Tax Act or make an accounting policy election for the ASC 740 treatment of the GILTI tax. Therefore, the Company has not recorded any amounts related to potential GILTI tax in its financial statements and has not yet made a policy decision regarding whether to record deferred taxes on GILTI.

Indefinite reinvestment assertion: Beginning in 2018, the Tax Act provides a 100% deduction for dividends received from 10-percent owned foreign corporations by U.S. corporate shareholders, subject to a one-year holding period. Although dividend income is now exempt from U.S. federal tax in the hands of the U.S. corporate shareholders, companies must still apply the guidance of ASC 740 to account for the tax consequences of outside basis differences and other tax impacts of their investments in non-U.S. subsidiaries. While the Company has accrued the Transition Tax on the deemed repatriated earnings that were previously indefinitely reinvested, the Company was unable to determine a reasonable estimate of the remaining tax liability, if any, under the Tax Act for its remaining outside basis differences or evaluate how the Tax Act will affect the Company’s existing accounting position to indefinitely reinvest unremitted foreign earnings. Therefore, the Company has not included a provisional amount for this item in its financial statements for fiscal 2017. The Company will record amounts as needed for this item beginning in the first reporting period during the measurement period in which the Company obtains necessary information and is able to analyze and prepare a reasonable estimate.

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,

Other, net		(0.9	)%		(0.7	)%		0.1	%
Effective rate		25.5	%		24.1	%		31.9	%

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 28.0% to 25.0% over the period 2021 to 2022. The 7.9% decrease in the effective tax rate due to the U.S. tax rate change was the result of adopted tax legislation that reduces the corporate income tax rate in the U.S. from 35.0% to 21.0% effective January 1, 2018. The 15.6% increase in the effective tax rate due to the U.S. tax reform previously discussed. 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,

Total deferred income tax liabilities		325,156			406,633
Net deferred income tax liability	$	(179,412	)	$	(241,520	)

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, 2017, the valuation allowance for certain foreign carryforwards was $25.7 million primarily in Brazil, China, United Kingdom, and South Africa.

Net operating loss carry-forwards in the amount of $65.7 million expire in various periods from December 31, 2018 to December 31, 2037.

As of December 31, 2017, the liability for income taxes associated with unrecognized tax benefits was $6.9 million, of which $4.4 million, if recognized, would favorably affect the Company’s effective income tax rate. 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 tax rate. A reconciliation of the beginning and ending amount of the liability for income taxes associated with unrecognized tax benefits follows:

In thousands	2017			2016			2015
Gross liability for unrecognized tax benefits at beginning of year	$	8,423		$	10,557		$	12,596
Gross increases - unrecognized tax benefits in prior periods		2,466			6			—

Gross liability for unrecognized tax benefits at end of year	$	6,910		$	8,423		$	10,557

The Company includes interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2017, the total interest and penalties accrued was approximately $0.7 million and $0.1 million, respectively. As of December 31, 2016, the total interest and penalties accrued was approximately $0.8 million and $0.3 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 $5.2 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.

The Company’s non-vested restricted stock contains rights to receive nonforfeitable dividends, and thus are participating securities requiring the two-class method of computing earnings per share. The calculation of earnings per share for common stock shown above excludes the income attributable to the non-vested restricted stock from the numerator and excludes the dilutive impact of those shares from the denominator.

STOCK-BASED COMPENSATION PLANS

10. STOCK-BASED COMPENSATION

As of September 30, 2018, 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, as amended and restated (the “2011 Plan”) and the 2000 Stock Incentive Plan, as amended (the “2000 Plan”). The 2011 Plan has a term through May 10, 2027 and provides a maximum of 3,800,000 shares for grants or awards, plus any shares which remain available under the 2000 Plan. The amendment and restatement of the 2011 Plan was approved by stockholders of Wabtec on May 10, 2017. The Company also maintains a 1995 Non-Employee Directors’ Fee and Stock Option Plan as amended and restated (“the Directors Plan”).

Stock-based compensation expense was $6.4 million and $2.6 million for the three months ended September 30, 2018 and 2017, respectively. Included in stock-based compensation expense for the three months ended September 30, 2018 is $0.4 million of expense related to stock options, $2.3 million related to restricted stock, $2.3 million related to restricted stock units, $1.2 million related to incentive stock units and $0.2 million related to units issued for Directors' fees.

Stock-based compensation expense was $20.5 million and $14.5 million for the nine months ended September 30, 2018 and 2017, respectively. Included in stock-based compensation expense for the nine months ended September 30, 2018 is $1.2 million of expense related to stock options, $5.0 million related to restricted stock, $7.0 million related to restricted stock units, $6.4 million related to incentive stock units and $0.9 million related to units issued for Directors’ fees. At September 30, 2018, unamortized compensation expense related to stock options, non-vested restricted shares and incentive stock units expected to vest totaled $35.4 million.

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-year 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 the Directors Plan for the nine months ended September 30, 2018:



	Options			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life		Aggregate Intrinsic value (in thousands)
Outstanding at December 31, 2017		983,512		$	40.62		4.0	$	40,137
Granted		82,580			77.54				2,258
Exercised		(574,303	)		23.88				46,520
Canceled		(16,471	)		64.46				666
Outstanding at September 30, 2018		475,318			56.50		5.9		22,997
Exercisable at September 30, 2018		291,169			49.75		5.0		16,051

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:



	Nine Months Ended September 30,
	2018			2017
Dividend yield		0.31	%		0.23	%
Risk-free interest rate		2.78	%		2.17	%
Stock price volatility		23.9	%		23.4	%
Expected life (years)		5.0			5.0

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 U.S. Treasury bond rates for the expected life of the option.

Restricted Stock, Restricted Units and Incentive Stock Beginning in 2006, the Company adopted a restricted stock program. As provided for under the 2011 Plan and 2000 Plan, 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, with underlying shares of common stock being awarded in an amount ranging from 0% to 200% of the amount of initial incentive stock units granted. The incentive stock units included in the table below represent the number of incentive stock units that are expected to vest based on the Company’s estimate for meeting those established performance targets. As of September 30, 2018, the Company estimates that it will achieve 71%, 81% and 91% of the goals for the incentive stock awards expected to vest based on performance for the three-year periods ending December 31, 2018, 2019, and 2020, respectively, and has recorded incentive compensation expense accordingly. If our estimate of the number of these incentive 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 average of the high and low Wabtec stock price 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 the Directors Plan, and incentive stock units activity for the 2011 Plan and the 2000 Plan with related information for the nine months ended September 30, 2018:

12. STOCK-BASED COMPENSATION PLANS

As of December 31, 2017, 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, as amended and restated (the “2011 Plan”) and the 2000 Stock Incentive Plan, as amended (the “2000 Plan”). The 2011 Plan has a term through May 10, 2027 and as of December 31, 2017 the number of shares available for future grants under the 2011 Plan was 3,192,453 shares, which includes remaining shares to grant under the 2000 Plan. The amendment and restatement of the 2011 Plan was approved by stockholders of Wabtec on May 10, 2017. The Company also maintains a 1995 Non-Employee Directors’ Fee and Stock Option Plan as amended and restated (“the Directors Plan”). The amendment and restatement of the Directors Plan was approved by stockholders of Wabtec on May 10, 2017. 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, 2017, 2016 and 2015, the Company issued a total of 16,500, 16,972 and 11,256 shares of restricted stock to non-employee directors. The total number of shares issued under the plan as of December 31, 2017 was 881,192 shares.

Stock-based compensation expense for all of the plans was $21.3 million, $20.8 million and $26.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. The Company recognized associated tax benefits related to the stock-based compensation plans of $8.9 million, $14.9 million and $15.3 million for the respective periods. Included in the stock-based compensation expense for 2017 above is $1.7 million of expense related to stock options, $7.0 million related to non-vested restricted stock, $4.6 million related to restricted stock units, $6.5 million related to incentive stock units and $1.5 million related to units issued for Directors’ fees. At December 31, 2017, unamortized compensation expense related to those stock options, non-vested restricted shares and incentive stock units expected to vest totaled $24.6 million and will be recognized over a weighted average period of 1.2 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 year 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:

		983,512	$	40.62				802,609	$	32.52

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,
	2017			2016			2015
Dividend yield		0.23	%		0.26	%		0.14	%
Risk-free interest rate		2.2	%		1.5	%		1.8	%
Stock price volatility		23.4	%		26.9	%		27.3	%
Expected life (years)		5.0			5.0			5.0
Weighted average fair value of options granted during the year	$	20.69		$	14.96		$	24.41

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, 2017, the Company estimates that it will achieve 84%, 77% and 91% for the incentive stock units expected to vest based on performance for the three year periods ending December 31, 2017, 2018, and 2019, 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:

DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING

14. 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 gain 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 three and nine months ended September 30, 2018 and September 30, 2017, the amounts reclassified into income were not material.

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 $4.7 million for the three months ended September 30, 2018. 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 hedges discussed in the above sections as of September 30, 2018.



In millions	Designated			Non-Designated		Total
Gross notional amount	$	787.0		$	796.0	$	1,583.0

Fair Value:
Other current assets	$	—		$	4.7	$	4.7
Other current liabilities		(6.0	)		—		(6.0	)
Total	$	(6.0	)	$	4.7	$	(1.3	)

The following table summarizes the gross notional amounts and fair values of the designated and non-designated hedges discussed in the above sections as of December 31, 2017.



In millions	Designated		Non-Designated		Total
Gross notional amount	$	805.1	$	379.7	$	1,184.8

Fair Value:
Other current assets	$	3.5	$	2.1	$	5.6
Other current liabilities		—		—		—
Total	$	3.5	$	2.1	$	5.6

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. Refer to footnote 15 for further information on interest rate swaps.

As of September 30, 2018, the Company has recorded a current liability of $0.1 million and an accumulated other comprehensive loss of $0.1 million, net of tax, related to these agreements.

17. 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, 2017, the amount reclassified into income was $0.4 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 $2.1 million for the twelve months ended December 31, 2017. The notional amount and fair value of foreign exchange contracts that did not meet the criteria for hedge accounting at December 31, 2017 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:

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, 2017, the Company has recorded a current liability of $1.2 million and an accumulated other comprehensive loss of $0.7 million, net of tax, related to these agreements.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS

15. 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 September 30, 2018, which are included in other current liabilities on the Condensed Consolidated Balance sheet:



			Fair Value Measurements at September 30, 2018 Using

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 September 30, 2018 and December 31, 2017. 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 represent 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:



	September 30, 2018				December 31, 2017
In thousands	Carrying Value		Fair Value		Carrying Value		Fair Value
Interest rate swap agreement	$	87	$	87	$	1,163	$	1,163

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.

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.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	16. COMMITMENTS AND CONTINGENCIES 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. Further information and detail on these claims is described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, in Note 19 therein, filed on February 26, 2018. During the first nine months of 2018, there were no material changes to the information described in the Form 10-K. From time to time, the Company is involved in litigation related to claims arising out of the Company's operations in the ordinary course of business, including claims based on product liability, contracts, intellectual property, or other causes of action. Further information and detail on any potentially material litigation is as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, in Note 19 therein, filed on February 26, 2018. Except as described below, there have been no material changes to the information described in the Form 10-K. 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. Additionally, after filings by the Company, the US Patent & Trademark Office has granted Inter-Parties Review proceedings on ten (10) of the patents asserted by Siemens to contest their validity; the hearings began in April 2018 and will continue through November 2018. As of October 24, 2018, the USPTO has issued a decision in only one of the IPR hearings, finding the Siemens patent claims at issue in that hearing to be invalid. Despite the pendency of the remaining IPR proceedings, a trial is scheduled for January 19, 2019 on Siemens’ infringement claims. Wabtec’s counterclaims alleging that Siemens has violated three (3) of Wabtec’s patents have been severed from the initial case and are now a separate case pending in federal district court in Delaware. On August 1, 2018, Wabtec’s motion for a preliminary injunction against Siemens was denied after a hearing. On July 19, 2018, Siemens moved to amend its pleadings in this case to add new counterclaims alleging violations of federal antitrust and state trade practices laws; Siemens’ motion to amend was granted on October 3, 2018. Wabtec will file responsive pleadings and/or motions. Xorail, Inc., a wholly owned subsidiary of the Company (“Xorail”), has received notices from Denver Transit Constructors (“Denver Transit”) alleging breach of contract related to the operating of constant warning wireless crossings, and late delivery of the Train Management & Dispatch System (“TMDS”) for the Denver Eagle P3 Project, which is owned by the Denver Regional Transit District ("RTD"). No damages have been asserted for the alleged late delivery of the TMDS, and no formal claim has been filed. Xorail is in the final stages of successfully implementing a recovery plan concerning the TMDS issues. With regard to the wireless crossing issue, as of September 8, 2017, Denver Transit alleged that total damages were $36.8 million through July 31, 2017 and are continuing to accumulate. The majority of the damages stems from a delay in approval of the wireless crossing system by the Federal Railway Administration ("FRA") and the Public Utility Commission ("PUC"), resulting in the use of flaggers at all of the crossings pending approval of the wireless crossing system and certification of the crossings. Denver Transit has alleged that the delay is due to Xorail's failure to achieve constant warning times for the crossings in accordance with the approval requirements imposed by the FRA and PUC. Xorail has denied Denver Transit's assertions, asserting that its system satisfied the contractual requirements. No formal claim has been filed against Xorail by Denver Transit. Xorail has worked with Denver Transit to modify its system to meet the FRA's and PUC's previously undefined approval requirements. On September 28, 2017, the FRA granted a five year approval of the modified wireless crossing system as currently implemented. On March 28, 2018, the PUC granted its approval of the modified wireless crossing system as currently implemented, consistent with the approval previously granted by the FRA. In August 2018, Denver Transit completed the process of certifying the crossings and eliminating the use of flaggers. On September 21, 2018, DTC filed a complaint against RTD in Colorado state court for breach of contract related to non-payments and the costs for the flaggers, asserting a change-in-law arising from the FRA/PUC’s new certification requirements. The complaint generally supports Xorail’s position and does not name or implicate Xorail. On April 3, 2018, the United States Department of Justice entered into a proposed consent decree resolving allegations that the Company and Knorr-Bremse AG had maintained unlawful agreements not to compete for each other’s employees. The allegations also related to Faiveley Transport before it was acquired by the Company in November 2016. The proposed consent decree is pending review and approval by the U.S. District Court for the District of Columbia. No monetary fines or penalties have been imposed on the Company. The Company elected to settle this matter with the Department of Justice to avoid the cost and distraction of litigation. As of July 16, 2018, putative class action lawsuits have been filed in several different federal district courts naming the Company and Knorr as defendants in connection with the allegations contained in the proposed consent decree. The lawsuits seek unspecified damages on behalf of employees of the Company (including Faiveley Transport) and Knorr allegedly caused by the defendants’ actions. A federal Multi-District Litigation (MDL) Panel decided that cases will be consolidated and heard in the Western District of Pennsylvania. As of October 15, 2018, a total of at least 30 plaintiffs have filed class action claims relating to the alleged conspiracy. The litigation is in its very early stages and the Company does not believe that it has diminished competition for talent in the marketplace and intends to contest these claims vigorously.	19. 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. Xorail, Inc., a wholly owned subsidiary of the Company (“Xorail”), has received notices from Denver Transit Constructors (“Denver Transit”) alleging breach of contract related to the operating of constant warning wireless crossings, and late delivery of the Train Management & Dispatch System (“TMDS”) for the Denver Eagle P3 Project, which is owned by the Denver Regional Transit District (“RTD”). No damages have been asserted for the alleged late delivery of the TMDS, and Xorail is in the final stages of successfully implementing a recovery plan concerning the TMDS issues. With regard to the wireless crossings, as of September 8, 2017, Denver Transit alleged that total damages were $36.8 million through July 31, 2017, and are continuing to accumulate. The crossings have not been certified for use without flaggers, which Denver Transit alleges is due to Xorail’s failure to achieve constant warning times satisfactory to the Federal Railway Administration (“FRA”) and the Public Utility Commission (“PUC”). No claims have been filed by Denver Transit with regard to either issue. Xorail has denied Denver Transit’s assertions regarding the wireless crossings, and Denver Transit has also notified RTD that Denver Transit considers the new certification requirements imposed by FRA and/or PUC as a change in law, for which neither Denver Transit nor its subcontractors are liable. Xorail has worked with Denver Transit to modify its system to meet the FRA’s and PUC’s previously undefined, and evolving, certification requirements. On September 28, 2017, the FRA granted a 5 year approval of the modified wireless crossing system as currently implemented; however, the PUC has not granted approval of the modified system and therefore the crossings are still not certified for use without flaggers. Denver Transit and RTD are continuing to seek approval from PUC. The Company does not believe that it has any liability with respect to the wireless crossing issue. 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.

Segment Reporting [Abstract]

SEGMENT INFORMATION

17. SEGMENT INFORMATION

Wabtec has two reportable segments—the Freight Segment and the Transit Segment. 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 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash Equivalents Cash equivalents are highly liquid investments purchased with an original maturity of three months or less.

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.

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 $6.6 million, $4.0 million and $4.7 million for 2017, 2016 and 2015, respectively.

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.

During the twelve months ended December 31, 2017, the estimated fair values for customer relationships and current liabilities were adjusted by $21.8 million and $65.3 million, respectively, for changes to initial estimates based on information that existed at the date of acquisition. Additionally, the estimated fair values for accounts receivable and current liabilities were adjusted by $2.8 million and $36.2 million, respectively, to correct errors in the preliminary estimated fair values of the Faiveley Transport assets acquired and liabilities assumed. Other noncurrent assets were adjusted by $30.0 million to record the deferred tax impact of these adjustments. As a result of these adjustments and other immaterial adjustments related to changes to initial estimates based on information that existed at the date of acquisition, goodwill increased by $74.1 million. Accounts receivable and current liabilities were adjusted by $64.3 million to correct an error in the preliminary estimated fair values of Faiveley Transport assets and liabilities assumed related to a factoring arrangement with recourse.

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 deductible for tax purposes. The goodwill allocated to the Freight segment is $72.0 million and the goodwill allocated to the Transit segment is $1,190.4 million.

2018 Refinancing Credit Agreement

On June 8, 2018, the Company entered into a credit agreement (the “2018 Refinancing Credit Agreement”), which replaced the Company’s then-existing “2016 Refinancing Credit Agreement.” As part of the 2018 Refinancing Credit Agreement, the Company entered into (i) a $1.2 billion revolving credit facility (the “Revolving Credit Facility”), which replaced the Company’s revolving credit facility under the 2016 Refinancing Credit Agreement, and includes a letter of credit sub-facility of up to $450.0 million and a swing line sub-facility of $75.0 million, (ii) a $350.0 million term loan (the “Refinancing Term Loan”), which refinanced the term loan under the 2016 Refinancing Credit Agreement, and (iii) a new $400.0 million delayed draw term loan (the “Delayed Draw Term Loan”). The 2018 Refinancing Credit Agreement also provides for a bridge loan facility (the “Bridge Loan Facility”) in an amount not to exceed $2.5 billion, such facility to become effective at the Company’s request. Commitments in respect of the Bridge Loan Facility will be reduced by any alternative financing (including any other loans or any long-term notes) that the Company arranges prior to the Direct Sale, subject to customary exceptions. In addition, the 2018 Refinancing Credit Agreement contains an uncommitted accordion feature allowing the Company to request, in an aggregate amount not to exceed $600.0 million, increases to the borrowing commitments under the Revolving Credit Facility or a new incremental term loan commitment.

The Revolving Credit Facility matures on June 8, 2023 and is unsecured. The Refinancing Term Loan matures on June 8, 2021 and is unsecured. The Delayed Draw Term Loan matures on the third anniversary of the date on which it is borrowed and is unsecured. The Bridge Loan Facility, if used, will mature on the date set forth in the definitive documentation for the Bridge Loan Facility and is unsecured. The applicable interest rate for borrowings under the 2018 Refinancing Credit Agreement includes interest rate spreads based on the lower of the pricing corresponding to (i) the Company’s ratio of total debt (less unrestricted cash up to $300.0 million) to EBITDA (“Leverage Ratio”) or (ii) the Company’s public rating, in each case that range between 1.000% and 1.875% for LIBOR/CDOR-based borrowings and 0.000% and 0.875% for Alternate Base Rate based borrowings. The obligations of the Company under the 2018 Refinancing Credit Agreement have been guaranteed by certain of the Company’s subsidiaries.

The 2018 Refinancing Credit Agreement contains customary representations and warranties by the Company and its subsidiaries, including customary use of materiality, material adverse effect, and knowledge qualifiers. The Company and its subsidiaries are also subject to (i) customary affirmative covenants that impose certain reporting obligations on the Company and its subsidiaries and (ii) customary negative covenants, including limitations on: indebtedness; liens; restricted payments; fundamental changes; business activities; transactions with affiliates; restrictive agreements; changes in fiscal year; and use of proceeds. In addition, the Company is required to maintain (i) an Interest Coverage ratio at least 3.00 to 1.00 over each period of four consecutive fiscal quarters ending on the last day of a fiscal quarter and (ii) a Leverage Ratio, calculated as of the last day of a fiscal quarter for a period of four consecutive fiscal quarters, of 3.25 to 1.00 or less; provided that, in the event the Company completes the Direct Sale and the Merger or any other material acquisition in which the cash consideration paid exceeds $500.0 million, the maximum Leverage Ratio permitted will be (x) 3.75 to 1.00 at the end of the fiscal quarter in which such acquisition is consummated and each of the three fiscal quarters immediately following such fiscal quarter and (y) 3.50 to 1.00 at the end of each of the fourth and fifth full fiscal quarters after the consummation of such acquisition. The Company is in compliance with the restrictions and covenants of the 2018 Refinancing Credit Agreement and does not expect that these measurements will limit the Company in executing its operating activities.

2016 Refinancing Credit Agreement

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.

(1)	The Company’s contribution represents more than 5% of the total contributions to the plan.

(2)	The Pension Fund’s board adopted a Funding Improvement Plan on October 21, 2015, continuing the existing plan which increased the weekly pension fund contribution rates by $75 with corresponding decreases to the weekly welfare fund contribution rates until December 31, 2017.

(3)	The number of employees covered by this fund decreased due to the closure of the Bensenville, Illinois facility, which affected the period-to-period comparability of 2016 and 2017 contributions.

(4)	Critical status triggered a 5% surcharge on employer contributions effective June 2012. Effective January 1, 2013, this surcharge increases to 10%. The surcharge ended on October 21, 2015 when the rehabilitation plan commenced.

(a)	The “EIN / PN” column provides the Employer Identification Number and the three-digit plan number assigned to a plan by the Internal Revenue Service.

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,
	2017			2016			2015
Dividend yield		0.23	%		0.26	%		0.14	%
Risk-free interest rate		2.2	%		1.5	%		1.8	%
Stock price volatility		23.4	%		26.9	%		27.3	%
Expected life (years)		5.0			5.0			5.0
Weighted average fair value of options granted during the year	$	20.69		$	14.96		$	24.41

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.

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, 2017, the Company estimates that it will achieve 84%, 77% and 91% for the incentive stock units expected to vest based on performance for the three year periods ending December 31, 2017, 2018, and 2019, 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.

11. INCOME TAXES

10. INCOME TAXES

Transition Tax on unrepatriated foreign earnings: The Transition Tax on unrepatriated foreign earnings is a tax on previously untaxed accumulated and current earnings and profits (“E&P”) of the Company’s foreign subsidiaries. To determine the amount of the Transition Tax, the Company must determine, among other factors, the amount of post-1986 E&P of its foreign subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. The Company was able to make a reasonable estimate of the Transition Tax and has recorded a provisional Transition Tax expense of $51.8 million. The Company is continuing to gather additional information to more precisely compute the amount of the Transition Tax to complete its calculation of E&P as well as the final determination of non-U.S. income taxes paid.

17. 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, 2017, the amount reclassified into income was $0.4 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 $2.1 million for the twelve months ended December 31, 2017. The notional amount and fair value of foreign exchange contracts that did not meet the criteria for hedge accounting at December 31, 2017 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	$	805.1	$	379.7	$	1,184.8

Fair Value:
Other current assets		3.5		2.1		5.6
Other current liabilities		—		—		—
Total	$	3.5	$	2.1	$	5.6

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, 2017, the Company has recorded a current liability of $1.2 million and an accumulated other comprehensive loss of $0.7 million, net of tax, related to these agreements.

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, 2017 and December 31, 2016. The Company’s defined benefit pension plan assets consist primarily of equity security funds, debt security funds and temporary cash and cash equivalent investments. 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	16. COMMITMENTS AND CONTINGENCIES 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. Further information and detail on these claims is described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, in Note 19 therein, filed on February 26, 2018. During the first nine months of 2018, there were no material changes to the information described in the Form 10-K. From time to time, the Company is involved in litigation related to claims arising out of the Company's operations in the ordinary course of business, including claims based on product liability, contracts, intellectual property, or other causes of action. Further information and detail on any potentially material litigation is as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, in Note 19 therein, filed on February 26, 2018. Except as described below, there have been no material changes to the information described in the Form 10-K. 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. Additionally, after filings by the Company, the US Patent & Trademark Office has granted Inter-Parties Review proceedings on ten (10) of the patents asserted by Siemens to contest their validity; the hearings began in April 2018 and will continue through November 2018. As of October 24, 2018, the USPTO has issued a decision in only one of the IPR hearings, finding the Siemens patent claims at issue in that hearing to be invalid. Despite the pendency of the remaining IPR proceedings, a trial is scheduled for January 19, 2019 on Siemens’ infringement claims. Wabtec’s counterclaims alleging that Siemens has violated three (3) of Wabtec’s patents have been severed from the initial case and are now a separate case pending in federal district court in Delaware. On August 1, 2018, Wabtec’s motion for a preliminary injunction against Siemens was denied after a hearing. On July 19, 2018, Siemens moved to amend its pleadings in this case to add new counterclaims alleging violations of federal antitrust and state trade practices laws; Siemens’ motion to amend was granted on October 3, 2018. Wabtec will file responsive pleadings and/or motions. Xorail, Inc., a wholly owned subsidiary of the Company (“Xorail”), has received notices from Denver Transit Constructors (“Denver Transit”) alleging breach of contract related to the operating of constant warning wireless crossings, and late delivery of the Train Management & Dispatch System (“TMDS”) for the Denver Eagle P3 Project, which is owned by the Denver Regional Transit District ("RTD"). No damages have been asserted for the alleged late delivery of the TMDS, and no formal claim has been filed. Xorail is in the final stages of successfully implementing a recovery plan concerning the TMDS issues. With regard to the wireless crossing issue, as of September 8, 2017, Denver Transit alleged that total damages were $36.8 million through July 31, 2017 and are continuing to accumulate. The majority of the damages stems from a delay in approval of the wireless crossing system by the Federal Railway Administration ("FRA") and the Public Utility Commission ("PUC"), resulting in the use of flaggers at all of the crossings pending approval of the wireless crossing system and certification of the crossings. Denver Transit has alleged that the delay is due to Xorail's failure to achieve constant warning times for the crossings in accordance with the approval requirements imposed by the FRA and PUC. Xorail has denied Denver Transit's assertions, asserting that its system satisfied the contractual requirements. No formal claim has been filed against Xorail by Denver Transit. Xorail has worked with Denver Transit to modify its system to meet the FRA's and PUC's previously undefined approval requirements. On September 28, 2017, the FRA granted a five year approval of the modified wireless crossing system as currently implemented. On March 28, 2018, the PUC granted its approval of the modified wireless crossing system as currently implemented, consistent with the approval previously granted by the FRA. In August 2018, Denver Transit completed the process of certifying the crossings and eliminating the use of flaggers. On September 21, 2018, DTC filed a complaint against RTD in Colorado state court for breach of contract related to non-payments and the costs for the flaggers, asserting a change-in-law arising from the FRA/PUC’s new certification requirements. The complaint generally supports Xorail’s position and does not name or implicate Xorail. On April 3, 2018, the United States Department of Justice entered into a proposed consent decree resolving allegations that the Company and Knorr-Bremse AG had maintained unlawful agreements not to compete for each other’s employees. The allegations also related to Faiveley Transport before it was acquired by the Company in November 2016. The proposed consent decree is pending review and approval by the U.S. District Court for the District of Columbia. No monetary fines or penalties have been imposed on the Company. The Company elected to settle this matter with the Department of Justice to avoid the cost and distraction of litigation. As of July 16, 2018, putative class action lawsuits have been filed in several different federal district courts naming the Company and Knorr as defendants in connection with the allegations contained in the proposed consent decree. The lawsuits seek unspecified damages on behalf of employees of the Company (including Faiveley Transport) and Knorr allegedly caused by the defendants’ actions. A federal Multi-District Litigation (MDL) Panel decided that cases will be consolidated and heard in the Western District of Pennsylvania. As of October 15, 2018, a total of at least 30 plaintiffs have filed class action claims relating to the alleged conspiracy. The litigation is in its very early stages and the Company does not believe that it has diminished competition for talent in the marketplace and intends to contest these claims vigorously.	19. 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. Xorail, Inc., a wholly owned subsidiary of the Company (“Xorail”), has received notices from Denver Transit Constructors (“Denver Transit”) alleging breach of contract related to the operating of constant warning wireless crossings, and late delivery of the Train Management & Dispatch System (“TMDS”) for the Denver Eagle P3 Project, which is owned by the Denver Regional Transit District (“RTD”). No damages have been asserted for the alleged late delivery of the TMDS, and Xorail is in the final stages of successfully implementing a recovery plan concerning the TMDS issues. With regard to the wireless crossings, as of September 8, 2017, Denver Transit alleged that total damages were $36.8 million through July 31, 2017, and are continuing to accumulate. The crossings have not been certified for use without flaggers, which Denver Transit alleges is due to Xorail’s failure to achieve constant warning times satisfactory to the Federal Railway Administration (“FRA”) and the Public Utility Commission (“PUC”). No claims have been filed by Denver Transit with regard to either issue. Xorail has denied Denver Transit’s assertions regarding the wireless crossings, and Denver Transit has also notified RTD that Denver Transit considers the new certification requirements imposed by FRA and/or PUC as a change in law, for which neither Denver Transit nor its subcontractors are liable. Xorail has worked with Denver Transit to modify its system to meet the FRA’s and PUC’s previously undefined, and evolving, certification requirements. On September 28, 2017, the FRA granted a 5 year approval of the modified wireless crossing system as currently implemented; however, the PUC has not granted approval of the modified system and therefore the crossings are still not certified for use without flaggers. Denver Transit and RTD are continuing to seek approval from PUC. The Company does not believe that it has any liability with respect to the wireless crossing issue. 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.

20. SEGMENT INFORMATION

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 ACCOUNTING POLICIES (FY) (Policies)	9 Months Ended	12 Months Ended
	Sep. 30, 2018	Dec. 31, 2017
Accounting Policies [Abstract]
Principles of Consolidation		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 Cash equivalents are highly liquid investments purchased with an original maturity of three months or less.
Allowance for Doubtful Accounts		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 $12.3 million and $7.3 million as of December 31, 2017 and 2016, respectively.
Inventories		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 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		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 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 2017, 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 50% and 50%, respectively, in arriving at fair value. 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, 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 Warranty costs are accrued based on Management’s estimates of repair or upgrade costs per unit and historical experience. Warranty expense was $50.4 million, $28.9 million and $35.4 million for 2017, 2016 and 2015, respectively. Accrued warranty was $153.1 million and $139.0 million at December 31, 2017 and 2016, respectively.
Income Taxes		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		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	Financial Derivatives and Hedging Activities As part of its risk management strategy, the Company utilizes derivative financial instruments to mitigate the impact of changes in foreign currencies and interest rates. For further information regarding financial derivatives and hedging activities, refer to Footnotes 14 and 15.	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, 2017, the Company has recorded a current liability of $1.2 million and a corresponding offset in accumulated other comprehensive loss of $0.7 million, net of tax, related to these agreements. For further information regarding the interest rate swap agreement, see Footnote 17.
Foreign Currency Translation	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 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.

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 $6.6 million, $4.0 million and $4.7 million for 2017, 2016 and 2015, respectively.
Noncontrolling Interests		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, 2017 and 2016. Net income attributable to noncontrolling interests was $8.5 million for the year ended December 31, 2016. Net income attributable to noncontrolling interest was not material for the years ended December 31, 2017 and 2015. Other comprehensive income attributable to noncontrolling interests for the years ended December 31, 2017, 2016 and 2015 was not material.
Revenue Recognition		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 $366.2 million and $274.9 million, customer deposits were $369.7 million and $256.6 million, and provisions for loss contracts were $94.0 million and $60.5 million at December 31, 2017 and 2016, 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 $20.2 million and $29.4 million at December 31, 2017 and 2016, respectively.
Significant Customers and Concentrations of Credit Risk		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 2017, 2016 or 2015.
Shipping and Handling Fees and Costs		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 Research and development costs are charged to expense as incurred. For the years ended December 31, 2017, 2016 and 2015, the Company incurred costs of approximately $95.2 million, $71.4 million, and $71.2 million, respectively.
Earnings Per Share		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)

Changes in facts and circumstances may result in revised estimates.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income". The amendments in this update address certain stranded income tax effects in accumulated other comprehensive income ("AOCI") resulting from the Tax Cuts and Jobs Act (the "Tax Act"). Current guidance requires the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that includes the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification would include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of the enactment of the Tax Act related to items in AOCI. The updated guidance is effective for reporting periods beginning after December 15, 2018 and is to be applied retrospectively to each period in which the effect of the Tax Act related to items remaining in AOCI are recognized or at the beginning of the period of adoption. Early adoption is permitted. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The amendments in this update eliminate the requirement to perform Step 2 of the goodwill impairment test. Instead, an entity should perform a goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value up to the carrying amount of the goodwill. This ASU is effective for public companies in the fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The impact of adopting this guidance could result in a change in the overall conclusion as to whether or not a reporting unit's goodwill is impaired and the amount of an impairment charge recognized in the event a reporting units' carrying value exceeds its fair value. All of the Company's reporting units had fair values that were substantially greater than the carrying value as of the Company's last quantitative goodwill impairment test, which was performed as of October 1, 2017. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements. 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 guidance requires enhanced disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases that will be effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company expects to adopt the requirements of the new standard effective January 1, 2019. The FASB recently proposed a transition alternative, which would allow for the application of the guidance at beginning of the period in which it is adopted, rather than requiring the adjustment of prior comparative periods. The Company plans to adopt this transition alternative. The Company plans to elect the practical expedient which does not require the capitalization of leases with terms of 12 months or less, and does not plan to elect the practical expedient which allows hindsight to be used to determine the term of a lease. The Company has evaluated its lease portfolio and is assessing the impact to the consolidated financial statements. The Company is in the process of implementing processes and information technology tools to assist in its ongoing lease data collection and analysis and evaluating its accounting policies and internal controls that would be impacted by the new guidance, to ensure readiness for adoption in the first quarter of 2019. Recently Adopted Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contract with Customers.” This ASU supersedes most of the previous revenue recognition requirements in U.S. GAAP and requires 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. This ASU became effective for public companies during interim and annual reporting periods beginning after December 15, 2017. The Company adopted this accounting standard update using the modified retrospective method. The impact of adopting the new standard was not material to the consolidated statement of income or the consolidated balance sheet. In March 2017, the FASB issued ASU No. 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost". The amendments in this update require the service cost component of net benefit costs to be reported in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit costs are required to be presented in the income statement separately from the service cost component and outside income from operations. This update also allows only the service cost component to be eligible for capitalization when applicable. This ASU became effective for public companies during interim and annual reporting periods beginning after December 15, 2017. In accordance with this update, the Company began recognizing the interest expense component of net periodic benefit cost in interest expense in the income statement and the expected return on plan assets, net amortization/deferrals, and curtailments in other income (expense), net in the income statement. This update has been applied retrospectively for presentation of the service cost component and other components of net benefit costs in accordance with this ASU and the impact of adoption resulted in increases of $0.3 million, $2.2 million and $2.5 million to selling, general, and administrative expense, interest expense, net and other income, net, respectively, in the income statement for the three months ended September 30, 2017. The impact of adoption resulted in increases of $1.0 million, $6.5 million and $7.5 million to selling, general, and administrative expense, interest expense, net and other income, net, respectively, in the income statement for the nine months ended September 30, 2017. Also, the capitalization of the service cost component of net benefit cost has been adopted prospectively in accordance with this ASU. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash". The amendments in this update require a statement of cash flows to 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. This ASU became effective for public companies during interim and annual reporting periods beginning after December 15, 2017. This update has been applied retrospectively and as a result restricted cash related to the acquisition of Faiveley Transport is included in the change in cash for the nine months ended September 30, 2017.	Recently Issued Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-02 “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. The amendments in this update address certain stranded income tax effects in accumulated other comprehensive income (“AOCI”) resulting from the Tax Cuts and Jobs Act (“TCJA”). Current guidance requires the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that includes the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification would include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of the enactment of TCJA related to items in AOCI. The updated guidance is effective for reporting periods beginning after December 15, 2018 and is to be applied retrospectively to each period in which the effect of the TCJA related to items remaining in AOCI are recognized or at the beginning of the period of adoption. Early adoption is permitted. The Company is currently evaluating the potential impact of adopting this guidance on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04 “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”.

Instead, an entity should perform a goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value up to the carrying amount of the goodwill.

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 to results is not anticipated to be material because the analysis of the Company’s current long-term contracts under the new revenue recognition standard supports the recognition of revenue over time under the cost-to-cost method for substantially all of our long-term 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 has evaluated new disclosure requirements and is implementing appropriate changes to its business processes and controls to support disclosure under the new guidance. Recently Adopted Accounting Pronouncements In March 2017, the FASB issued ASU No. 2017-07 “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. The amendments in this update require the service cost component of net benefit costs to be reported in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit costs are required to be presented in the income statement separately from the service cost component and outside income from operations. This update also allows the service cost component to be eligible for capitalization when applicable. In accordance with this update, the Company began recognizing the interest expense component of net periodic benefit cost in interest expense in the income statement and the expected return on plan assets, net amortization/deferrals, and curtailments in other income (expense), net in the income statement. This update has been adopted by the Company and applied retrospectively for presentation of the service cost component and other components of net benefit costs in accordance with the ASU. The impact of adoption resulted in increases of $0.6 million, $9.2 million and $9.8 million to selling, general, and administrative expense, interest expense, net and other income, net, respectively, in the income statement for the year ended December 31, 2017. The impact of adoption resulted in increases of $1.8 million, $7.7 million and $9.5 million to selling, general, and administrative expense, interest expense, net and other income, net, respectively, in the income statement for the year ended December 31, 2016. The impact of adoption resulted in a decrease of $1.3 million, an increase of $10.4 million and an increase of $9.1 million to selling, general, and administrative expense, interest expense, net and other income, net, respectively, in the income statement for the year ended December 31, 2015. Also, the capitalization of the service cost component of net benefit cost will be adopted prospectively in accordance with the ASU. In November 2016, the FASB issued ASU No. 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash”. The amendments in this update require a statement of cash flows to 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 requirements of this update have been adopted by the Company and applied retrospectively. As a result restricted cash related to the acquisition of Faiveley Transport is included in the change in cash for the years ended December 31, 2017, 2016 and 2015. 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 became effective for public companies during interim and annual reporting periods beginning after December 15, 2016. In accordance with this update, the Company began recognizing all excess tax deficiencies and tax benefits from share-based payment awards as a benefit or expense to income tax in the income statement. This update has been adopted prospectively in accordance with the ASU and the impact of adoption on the income statement was not material. Additionally, in accordance with this update, the Company began classifying excess income tax benefits from exercise of stock options as an operating activity on the consolidated statement of cash flows. The Company elected to adopt this amendment retrospectively and the impact of the adoption on operating and financing cash flows was not material.

Use of Estimates

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.

Financial Derivatives and Hedging Activities

Foreign Currency Translation

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 $6.6 million, $4.0 million and $4.7 million for 2017, 2016 and 2015, respectively.
