	2. ACCOUNTING POLICIES
	Basis of Presentation The unaudited condensed consolidated interim financial statements have been prepared in accordance with generally accepted accounting principles and the rules and regulations of the Securities and Exchange Commission and include the accounts of Wabtec and its majority owned subsidiaries. These condensed consolidated interim financial statements do not include all of the information and footnotes required for complete financial statements. In management’s opinion, these financial statements reflect all adjustments of a normal, recurring nature necessary for a fair presentation of the results for the interim periods presented. Results for these interim periods are not necessarily indicative of results to be expected for the full year.
	The Company operates on a four-four-five week accounting quarter, and the quarters’ end on or about March 31, June 30, September 30 and December 31.
	The notes included herein should be read in conjunction with the audited consolidated financial statements included in Wabtec’s Annual Report on Form 10-K for the year ended December 31, 2012. The December 31, 2012 information has been derived from the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.
	Capital Structure On May 14, 2013, our stockholders approved an amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of our common stock to 200.0 million shares.  In addition, on May 14, 2013, our Board of Directors approved a two-for-one split of the Company’s issued and outstanding common stock in the form of a 100% stock dividend.  The increase in the authorized shares and the stock split became effective on May 14, 2013 and June 11, 2013, respectively.
	The Company issued approximately 66.2 million shares of its common stock as a result of the two-for-one stock split. The par value of the Company’s common stock remained unchanged at $0.01 per share.
	Information regarding shares of common stock (except par value per share), retained earnings, and net income per common share attributable to Wabtec shareholders for all periods presented reflects the two-for-one split of the Company’s common stock. The number of shares of the Company’s common stock issuable upon exercise of outstanding stock options and vesting of other stock-based awards was proportionally increased, and the exercise price per share thereof was proportionally decreased, in accordance with the terms of the stock incentive plans.
	Reclassifications Certain prior year amounts have been reclassified where necessary to conform to the current year presentation.
	Revenue Recognition Revenue is recognized in accordance with Accounting Standards Codification (“ASC”) 605 “Revenue Recognition”. Revenue is recognized when products have been shipped to the respective customers, title has passed and the price for the product has been determined.
	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 at a minimum quarterly 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 $213.5 million and $97.1 million, customer deposits were $70.9 million and $82.8 million, and provisions for loss contracts were $13.8 million and $14.2 million at September 30, 2013 and December 31, 2012, 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 $17.8 million and $20.5 million at September 30, 2013 and December 31, 2012, respectively.
	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 The Company has periodically entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. Forward contracts are agreements with a counter-party 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. At September 30, 2013, the Company had no material foreign currency forward contracts.
	To reduce the impact of interest rate changes on a portion of its variable-rate debt, the Company entered into a forward starting interest rate swap agreement with a notional value of $150.0 million. Effective July 31, 2013, with a termination date of November 7, 2016, this interest rate swap agreement converts a portion of the Company’s then outstanding debt from a variable rate to a fixed-rate borrowing. The Company is exposed to credit risk in the event of nonperformance by the counterparty. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparty is a large financial institution with an excellent credit rating and history of performance. The Company currently believes the risk of nonperformance is negligible. The Company concluded that the interest rate swap agreement qualifies for special cash flow hedge accounting which requires the recording of the fair value of the interest rate swap agreement and permits the corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. During the term of the interest rate swap agreement the interest rate on the notional value will be fixed at 1.415% plus the Alternate Rate margin. As of September 30, 2013, the Company has recorded a current liability of $3.3million and a corresponding offset in accumulated other comprehensive loss of $2.0 million, net of tax, related to this agreement.
	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 year. 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. Foreign exchange transaction losses recognized in other income (expense), net were $1.0 million and $2.9 million for the three and nine months ended September 30, 2013, respectively. Foreign exchange transaction losses recognized in other income (expense), net were $1.4 million and $0.4 million for the three and nine months ended September 30, 2012, respectively.
	Non-controlling Interests In accordance with ASC 810, the Company has classified non-controlling interests as equity on our condensed consolidated balance sheets as of September 30, 2013 and December 31, 2012. Net income attributable to non-controlling interests for the three and nine months ended September 30, 2013 and 2012 was not material.
	Other Comprehensive Income Comprehensive income is defined as net income and all other non-owner changes in shareholders’ equity.
	The changes in accumulated other comprehensive loss by component, net of tax, for the nine months ended September 30, 2013 are as follows:

	2011 Refinancing Credit Agreement
	On November 7, 2011, the Company refinanced its existing revolving credit and term loan facility with a consortium of commercial banks. This “2011 Refinancing Credit Agreement” provides the Company with a $600 million, five-year revolving credit facility. The Company incurred approximately $1.9 million of deferred financing cost related to the 2011 Refinancing Credit Agreement. The facility expires on November 7, 2016. The 2011 Refinancing Credit Agreement borrowings bear variable interest rates indexed to the indices described below. At September 30, 2013, the Company had available bank borrowing capacity, net of $60.1 million of letters of credit, of approximately $250.9 million, subject to certain financial covenant restrictions.
	Under the 2011 Refinancing Credit Agreement, the Company may elect a Base Rate of interest or an interest rate based on the London Interbank Offered Rate (“LIBOR”) of interest (“the Alternate Rate”). The Base Rate adjusts on a daily basis and is 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 is based on quoted LIBOR rates plus a margin that ranges from 75 to 175 basis points. Both the Base Rate and Alternate Rate margins are dependent on the Company’s consolidated total indebtedness to cash flow ratios. The current Base Rate margin is 0 basis points and the Alternate Rate margin is 100 basis points.
	At September 30, 2013 the weighted average interest rate on the Company’s variable rate debt was 1.19%. On January 12, 2012, the Company entered into a forward starting interest rate swap agreement with a notional value of $150.0 million. The effective date of the interest rate swap agreement was July 31, 2013, and the termination date is November 7, 2016. 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 1.415% plus the Alternate Rate margin. The Company is exposed to credit risk in the event of nonperformance by the counterparty. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparty is a large financial institution with an excellent credit rating and history of performance. The Company currently believes the risk of nonperformance is negligible.
	The 2011 Refinancing Credit Agreement limits the Company’s ability to declare or pay cash dividends and prohibits the Company from declaring or making other distributions, subject to certain exceptions. The 2011 Refinancing Credit Agreement contains various other covenants and restrictions including the following limitations: incurrence of additional indebtedness; mergers, consolidations, sales of assets and acquisitions; additional liens; sale and leasebacks; permissible investments, loans and advances; certain debt payments; and imposes a minimum interest expense coverage ratio of 3.0 and a maximum debt to cash flow ratio of 3.25. The Company does not expect that these measurements will limit the Company in executing our operating activities.
	4.375% Senior Notes Due August 2023
	In August 2013, the Company issued $250.0 million of Senior Notes due in 2023 (“the 2013 Notes”).  The 2013 Notes were issued at 99.879% of face value.  Interest on the 2013 Notes accrues at a rate of 4.375% per annum and is payable semi-annually on February 15 and August 15 of each year.  The proceeds were used to repay debt outstanding under the Company’s existing credit agreement, and for general corporate purposes.  The principal balance is due in full at maturity.  The Company incurred $2.6 million of deferred financing costs related to the issuance.
	The Notes are senior unsecured obligations of the Company and rank pari passu with all existing and future senior debt and senior to all existing and future subordinated indebtedness of the Company. The indenture under which the Notes were issued contains covenants and restrictions which limit among other things, the following: the incurrence of indebtedness, payment of dividends and certain distributions, sale of assets, change in control, mergers and consolidations and the incurrence of liens.
	The Company is in compliance with the restrictions and covenants in the indenture under which the Notes were issued and expects that these restrictions and covenants will not be any type of limiting factor in executing our operating activities.
	6.875% Senior Notes Due July 31, 2013
	In August 2003, the Company issued $150.0 million of Senior Notes due in 2013 (“the 2003 Notes”). The 2003 Notes were issued at par. Interest on the 2003 Notes accrued at a rate of 6.875% per annum and was payable semi-annually on January 31 and July 31 of each year. The proceeds were used to repay debt outstanding under the Company’s existing credit agreement, and for general corporate purposes. The Company paid off the 2003 Notes, which matured on July 31, 2013 utilizing available capacity under the 2011 Refinancing Credit Agreement.

Stockbased_Compensation

Stock-based Compensation	9 Months Ended

Stock-based Compensation	'
	8. STOCK-BASED COMPENSATION
	As of September 30, 2013, the Company maintains employee stock-based compensation plans for stock options, restricted stock, restricted units, and incentive stock awards as governed by the 2011 Stock Incentive Compensation Plan (the “2011 Plan”) and the 2000 Stock Incentive Plan, as amended (the “2000 Plan”). The 2011 Plan has a 10-year term through March 27, 2021 and provides a maximum of 3,800,000 shares for grants or awards. The 2011 Plan was approved by stockholders of Wabtec on May 11, 2011. The Company also maintains a Non-Employee Directors’ Fee and Stock Option Plan (“Directors Plan”). No awards may be made under the 2000 Plan or the Directors Plan subsequent to October 31, 2016.
	Stock-based compensation expense was $17.6 million and $15.4 million for the nine months ended September 30, 2013 and 2012, respectively. Included in the stock-based compensation expense for the nine months ended September 30, 2013 above is $1.7 million of expense related to stock options, $3.9 million related to restricted stock, $1.3 million related to restricted units, $10.0 million related to incentive stock awards and $0.7 million related to awards issued for Directors’ fees. At September 30, 2013, unamortized compensation expense related to stock options, restricted stock, restricted units and incentive stock awards expected to vest totaled $25.9 million and will be recognized over a weighted average period of 1.4 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 the Directors Plan for the nine months ended September 30, 2013:
		Options				Weighted					Weighted Average			Aggregate

	Exercisable at September 30, 2013		819,483			$		18.83				5.5		$	35,834
	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,
		2013					2012
	Dividend yield		.21		%			.23		%
	Risk-free interest rate		1.38		%			1.35		%
	Stock price volatility		43.8		%			44.95		%
	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 and 2000 Plans, eligible employees are granted restricted stock or restricted units that generally vest over four years from the date of grant. Under the Directors Plan, restricted stock awards vest one year from the date of grant.
	In addition, the Company has issued incentive stock awards 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 awards can vest and be awarded ranging from 0% to 200% of the initial incentive stock awards granted. The incentive stock awards 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 September 30, 2013, the Company estimates that it will achieve 200%, 168% and 100% for the incentive stock awards expected to vest based on performance for the three-year periods ending December 31, 2013, 2014, and 2015, respectively, and has recorded incentive compensation expense accordingly. If our estimate of the number of these stock awards 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 restricted stock and incentive stock awards 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 and unit activity for the 2011 Plan, the 2000 Plan and the Directors Plan, and incentive stock awards activity for the 2011 Plan and the 2000 Plan with related information for the nine months ended September 30, 2013:

	9. INCOME TAXES
	The overall effective income tax rate was 29.2% and 30.4% for the three and nine months ended September 30, 2013, respectively, and 31.8% and 33.3% for the three and nine months ended September 30, 2012, respectively. For the three months ended September 30, 2013, the decrease in the effective rate is primarily due to a benefit recorded for the enacted reduction of a foreign statutory tax rate. For the nine months ended September 30, 2013, the effective rate also includes benefits for the retroactive extension of the R&D tax credit and an increase in foreign income taxed at a lower statutory rates.
	As of September 30, 2013, the liability for income taxes associated with uncertain tax positions is $10.9 million, of which $4.1 million, if recognized, would favorably affect the Company’s effective tax rate. As of December 31, 2012 the liability associated with uncertain tax positions was $11.3 million, of which $3.7 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. As of September 30, 2013 and December 31, 2012 the total accrued interest and penalties are $2.5 million and $1.4 million, respectively.
	At this time, the Company believes that it is reasonably possible that unrecognized tax benefits of approximately $1.6 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.  With limited exception, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for years before 2011.

Fair Value Measurement and Fair Value of Financial Instruments

12. 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, 2013, which are included in other current liabilities on the Condensed Consolidated Balance sheet:

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, 2013 and December 31, 2012. 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. The 2013 Notes and the 2003 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:

Segment Information	'
	14. 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, friction products, 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 subway cars and buses, builds new commuter locomotives, friction products, and refurbishes subway cars. 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. 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.

Basis of Presentation

'

Basis of Presentation The unaudited condensed consolidated interim financial statements have been prepared in accordance with generally accepted accounting principles and the rules and regulations of the Securities and Exchange Commission and include the accounts of Wabtec and its majority owned subsidiaries. These condensed consolidated interim financial statements do not include all of the information and footnotes required for complete financial statements. In management’s opinion, these financial statements reflect all adjustments of a normal, recurring nature necessary for a fair presentation of the results for the interim periods presented. Results for these interim periods are not necessarily indicative of results to be expected for the full year.

The Company operates on a four-four-five week accounting quarter, and the quarters’ end on or about March 31, June 30, September 30 and December 31.

The notes included herein should be read in conjunction with the audited consolidated financial statements included in Wabtec’s Annual Report on Form 10-K for the year ended December 31, 2012. The December 31, 2012 information has been derived from the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Capital Structure

'

Capital Structure On May 14, 2013, our stockholders approved an amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of our common stock to 200.0 million shares.  In addition, on May 14, 2013, our Board of Directors approved a two-for-one split of the Company’s issued and outstanding common stock in the form of a 100% stock dividend.  The increase in the authorized shares and the stock split became effective on May 14, 2013 and June 11, 2013, respectively.

The Company issued approximately 66.2 million shares of its common stock as a result of the two-for-one stock split. The par value of the Company’s common stock remained unchanged at $0.01 per share.

Information regarding shares of common stock (except par value per share), retained earnings, and net income per common share attributable to Wabtec shareholders for all periods presented reflects the two-for-one split of the Company’s common stock. The number of shares of the Company’s common stock issuable upon exercise of outstanding stock options and vesting of other stock-based awards was proportionally increased, and the exercise price per share thereof was proportionally decreased, in accordance with the terms of the stock incentive plans.

Reclassifications

'

Reclassifications Certain prior year amounts have been reclassified where necessary to conform to the current year presentation.

Revenue Recognition

'

Revenue Recognition Revenue is recognized in accordance with Accounting Standards Codification (“ASC”) 605 “Revenue Recognition”. Revenue is recognized when products have been shipped to the respective customers, title has passed and the price for the product has been determined.

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 at a minimum quarterly 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 $213.5 million and $97.1 million, customer deposits were $70.9 million and $82.8 million, and provisions for loss contracts were $13.8 million and $14.2 million at September 30, 2013 and December 31, 2012, 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 $17.8 million and $20.5 million at September 30, 2013 and December 31, 2012, respectively.

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

'

Financial Derivatives and Hedging Activities The Company has periodically entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. Forward contracts are agreements with a counter-party 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. At September 30, 2013, the Company had no material foreign currency forward contracts.

To reduce the impact of interest rate changes on a portion of its variable-rate debt, the Company entered into a forward starting interest rate swap agreement with a notional value of $150.0 million. Effective July 31, 2013, with a termination date of November 7, 2016, this interest rate swap agreement converts a portion of the Company’s then outstanding debt from a variable rate to a fixed-rate borrowing. The Company is exposed to credit risk in the event of nonperformance by the counterparty. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparty is a large financial institution with an excellent credit rating and history of performance. The Company currently believes the risk of nonperformance is negligible. The Company concluded that the interest rate swap agreement qualifies for special cash flow hedge accounting which requires the recording of the fair value of the interest rate swap agreement and permits the corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. During the term of the interest rate swap agreement the interest rate on the notional value will be fixed at 1.415% plus the Alternate Rate margin. As of September 30, 2013, the Company has recorded a current liability of $3.3million and a corresponding offset in accumulated other comprehensive loss of $2.0 million, net of tax, related to this agreement.

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 year. 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. Foreign exchange transaction losses recognized in other income (expense), net were $1.0 million and $2.9 million for the three and nine months ended September 30, 2013, respectively. Foreign exchange transaction losses recognized in other income (expense), net were $1.4 million and $0.4 million for the three and nine months ended September 30, 2012, respectively.

Non-controlling Interests

'

Non-controlling Interests In accordance with ASC 810, the Company has classified non-controlling interests as equity on our condensed consolidated balance sheets as of September 30, 2013 and December 31, 2012. Net income attributable to non-controlling interests for the three and nine months ended September 30, 2013 and 2012 was not material.

Other Comprehensive Income

Other Comprehensive Income Comprehensive income is defined as net income and all other non-owner changes in shareholders’ equity.

The changes in accumulated other comprehensive loss by component, net of tax, for the nine months ended September 30, 2013 are as follows:
