Summary Of Significant Accounting Policies

2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. Such statements have been prepared in accordance with generally accepted accounting principles. Sales between subsidiaries are billed at prices consistent with sales to third parties and are eliminated in consolidation.

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

Allowance for Doubtful Accounts The allowance for doubtful accounts receivable reflects our best estimate of probable losses inherent in our receivable portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. The allowance for doubtful accounts was $8.4 million and $7.5 million as of December 31, 2011 and 2010, respectively.

Inventories Inventories are stated at the lower of cost or market. Cost is determined under the first-in, first-out (FIFO) method. Inventory costs include material, labor and overhead.

Property, Plant and Equipment Property, plant and equipment additions are stated at cost. Expenditures for renewals and improvements are capitalized. Expenditures for ordinary maintenance and repairs are expensed as incurred. The Company provides for book depreciation principally on the straight-line method. Accelerated depreciation methods are utilized for income tax purposes.

Leasing Arrangements The Company conducts a portion of its operations from leased facilities and finances certain equipment purchases through lease agreements. In those cases in which the lease term approximates the useful life of the leased asset or the lease meets certain other prerequisites, the leasing arrangement is classified as a capital lease. The remaining arrangements are treated as operating leases.

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 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.

In September 2011, the FASB issued Accounting Standards Updated ("ASU") 2011-08 which amends the rules for testing goodwill for impairment. Under the new rules, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. We adopted ASU 2011-08 for our 2011 annual goodwill impairment test.

In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we assess relevant events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit's fair value or carrying amount involve significant judgments and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact.

If our qualitative assessment concludes that it is probable that we have an impairment, the Company then performs a quantitative assessment. 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 Company reviews goodwill for impairment at the reporting unit level. The Company prepares its goodwill impairment analysis by comparing the estimated fair value of each reporting unit, using an income approach (a discounted cash flow model) as well as a market approach, with its carrying value. The income approach and the market approach are equally weighted in arriving at fair value, which the Company has applied consistently.

The discounted cash flow model requires several assumptions including future sales growth, EBIT (earnings before interest and taxes) margins and capital expenditures for the reporting units. The discounted cash flow model also requires the use of a discount rate and a terminal revenue growth rate (the revenue growth rate for the period beyond the three 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.

Warranty Costs Warranty costs are accrued based on Management's estimates of repair or upgrade costs per unit and historical experience. Warranty expense was $19.9 million, $22.8 million and $20.4 million for 2011, 2010 and 2009, respectively. Accrued warranty was $50.6 million and $35.5 million at December 31, 2011 and 2010, respectively.

Income Taxes Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws. The provision for income taxes includes federal, state and foreign income taxes.

Stock-Based Compensation The Company recognizes compensation expense for stock-based compensation based on the grant date fair value amortized ratably over the requisite service period following the date of grant.

Financial Derivatives and Hedging Activities The Company has entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. 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. At December 31, 2011, the Company had no forward contracts.

At December 31, 2010, the Company had forward contracts for the sale of South African Rand (ZAR) and the purchase of U.S. Dollars (USD). The Company concluded that these foreign currency forward contracts qualify for cash flow hedge accounting which permits the recording of the fair value of the forward contract and corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. As of December 31, 2010, the Company had forward contracts with a notional value of 24.7million ZAR (or $3.4 million U.S.) with an average exchange rate of 7.19 ZAR per $1 USD, resulting in the recording of a current liability of $192,000 and a corresponding offset in accumulated other comprehensive income of $122,000, net of tax.

To reduce the impact of interest rate changes on a portion of this variable-rate debt, the Company entered into interest rate swap agreements which effectively converted a portion of the debt from a variable to a fixed-rate borrowing during the term of the swap contract. 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 agreements qualify for special cash flow hedge accounting which permits the recording of the fair value of the interest rate swap agreement and corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. As of December 31, 2011, the Company had interest rate swap agreements with a notional value of $107.0 million and which effectively changed the Company's interest rate on bank debt at December 31, 2011 from a variable rate to a fixed rate of 2.19%. The interest rate swap agreements mature on December 31, 2012. As of December 31, 2011, the Company recorded a current liability of $1.4 million and a corresponding offset in accumulated other comprehensive loss of $0.9 million, net of tax.

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 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 acumulated 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 $2.0 million, $1.0 million and $1.3 million for 2011, 2010 and 2009, respectively.

Noncontrolling Interests In accordance with ASC 810, the Company has classified noncontrolling interests as equity on our condensed consolidated balance sheets as of December 31, 2011 and 2010. Net income attributable to noncontrolling interests for the years ended December 31, 2011, 2010 and 2009 was not material.

Other Comprehensive Income (Loss) Comprehensive income (loss) is defined as net income and all other non-owner changes in shareholders' equity. The Company's accumulated other comprehensive income consists of foreign currency translation adjustments, foreign currency hedges, foreign exchange contracts, interest rate swaps, and pension and post retirement related adjustments.

Revenue Recognition Revenue is recognized in accordance with 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 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.

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 $15.4 million and $11.9 million at December 31, 2011 and 2010, respectively.

Significant Customers and Concentrations of Credit Risk The Company's trade receivables are from rail and transit industry original equipment manufacturers, Class I railroads, railroad carriers and commercial companies that utilize rail cars in their operations, such as utility and chemical companies. No one customer accounted for more than 10% of the Company's consolidated net sales in 2011, 2010 and 2009.

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 is classified as a component of cost of sales.

Research and Development Research and development costs are charged to expense as incurred. For the years ended December 31, 2011, 2010 and 2009, the Company incurred costs of approximately $37.2 million, $40.2 million and $42.4 million, respectively.

Employees As of December 31, 2011, approximately 25% of the Company's workforce was covered by collective bargaining agreements. These agreements are generally effective from 2012 through 2014. Agreements expiring in 2012 cover approximately 17% of the Company's workforce.

Earnings Per Share Basic and diluted earnings per common share is computed in accordance with ASC 260 "Earnings Per Share." Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and included in the computation of earnings per share pursuant to the two-class method included in ASC 260-10-55.

7.	INTANGIBLES

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. Goodwill and indefinite lived intangible assets are reviewed annually during the fourth quarter for impairment (See Note 2 "Summary of Significant Accounting Policies" included herein). Goodwill and indefinite live intangible assets were not impaired at December 31, 2011 and 2010.

Goodwill was $587.5 million and $545.8 million at December 31, 2011 and 2010, respectively. The change in the carrying amount of goodwill by segment for the year ended December 31, 2011 is 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 December 31, 2011, the Company had available bank borrowing capacity, net of $48.9 million of letters of credit, of approximately $306.1 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 initial Base Rate margin is 25 basis points and the Alternate Rate margin is 125 basis points.

At December 31, 2011 the weighted average interest rate on the Company's variable rate debt was 1.53%. To reduce the impact of interest rate changes on a portion of this variable-rate debt, the Company entered into interest rate swap agreements which effectively convert a portion of the debt from a variable to a fixed-rate borrowing during the term of the swap contracts. On December 31, 2011, the notional value of the interest rate swaps outstanding was $107.0 million and effectively changed the Company's interest rate on bank debt at December 31, 2011 from a variable rate to a fixed rate of 2.19%. The interest rate swap agreements mature on December 31, 2012. 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.

On January 12, 2012, the Company entered into a forward starting interest rate swap agreement with a notional value of $150 million. The effective date of the interest rate swap agreement is July 31, 2013, and the termination date is November 7, 2016. The impact of the interest rate swap agreement will be to convert a portion of the Company's then 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%. 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.

2008 Refinancing Credit Agreement

On November 4, 2008, the Company had refinanced its existing unsecured revolving credit agreement with a consortium of commercial banks. This "2008 Refinancing Credit Agreement" provided the company with a $300 million five-year revolving credit facility and a $200 million five-year term loan facility. The Company incurred $2.9 million of deferred financing cost related to the 2008 Refinancing Credit Agreement. Both facilities were set to expire in January 2013.

Under the 2008 Refinancing Credit Agreement, the Company may have elected 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 adjusted on a daily basis and is the greater of the PNC, N.A. prime rate, 30-day LIBOR plus 150 basis points or the Federal Funds Effective Rate plus 0.5% per annum, plus a margin that ranges from 25 to 50 basis points. The Alternate rate was based on quoted LIBOR rates plus a margin that ranges from 125 to 200 basis points. Both the Base Rate and Alternate Rate margins are dependent on the Company's consolidated total indebtedness to cash flow ratios.

6.875% Senior Notes Due August 2013

In August 2003, the Company issued $150 million of Senior Notes due in 2013 ("the Notes"). The Notes were issued at par. Interest on the Notes accrues at a rate of 6.875% per annum and is 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 principal balance is due in full at maturity.

The Notes are senior unsecured obligations of the Company and rank pari passu with all existing and future senior debt and senior to all our 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.

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 composition 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 passively managed and are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. Generally, all plan assets are considered Level 2 based on the fair value valuation hierarchy (See Note 17 "Fair Value Measurement" included herein). Plan assets by asset category at December 31, 2011 and 2010 are as follows:


	U.S.				International
*In thousands*	2011		2010		2011		2010
Pension Plan Assets
Equity security funds	$	19,669	$	24,282	$	76,679	$	74,501

Fair value of plan assets	$	39,951	$	39,738	$	131,327	$	125,568

The U.S. pension plan has a target asset allocation of 50% equity securities and 50% debt securities. The international pension plans have target asset allocations of 60% equity securities and 40% debt securities. Investment policies are determined by the respective Plan's Pension Committee and set forth in its Investment Policy. Rebalancing of the asset allocation occurs on a quarterly basis.

Cash Flows

The Company's funding methods are based on governmental requirements and differ from those methods used to recognize pension expense. The Company expects to contribute $1.7 million to the U.S. plans and $5.4 million to the international plans during 2012.

Benefit payments expected to be paid to plan participants are as follows:


*In thousands*	U.S.		International

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. The following tables provide information regarding the Company's post retirement benefit plans summarized by U.S. and international components.

The assumed health care cost trend rate for the U.S. plans grades from an initial rate of 7.4% to an ultimate rate of 4.5% by 2027 and for international plans from 8.2% to 4.5% by 2030. A 1% 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 postretirement plans by approximately $206,000 and $29,000, respectively, for 2012, and increase the accumulated postretirement benefit obligation by approximately $4.23 million and $269,000, respectively. A 1% 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 postretirement plans by approximately $175,000 and $24,000, respectively, for 2012, and decrease the accumulated postretirement benefit obligation by approximately $3.6 million and $233,000, 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*	2011		2010		2009
Multi-employer pension and health & welfare plans	$	1,574	$	1,130	$	1,233

Total	$	12,619	$	10,697	$	9,676

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, 2011 and 2010, the plan held on behalf of its participants about 403,400 shares with a market value of $28.2 million, and 433,300 shares with a market value of $22.9 million, respectively.

Additionally, the Company has stock option based benefit and other plans further described in Note 12.

The Company contributes to several multiemployer 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 multiemployer 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 multiemployer 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 multiemployer plan is required to pay to the plan is referred to as a withdrawal liability.

The Company's participation in multiemployer plans for the year ended December 31, 2011 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.

The most recent Pension Protection Act Zone Status available for 2010 and 2009 is for plan years that ended in 2010 and 2009, 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.

INCOME TAXES

The Company is responsible for filing consolidated U.S., foreign and combined, unitary or separate state income tax returns. The Company is responsible for paying the taxes relating to such returns, including any subsequent adjustments resulting from the redetermination of such tax liabilities by the applicable taxing authorities. The components of the income from operations before provision for income taxes for the Company's domestic and foreign operations for the years ended December 31 are provided below:


	For the year ended December 31,
*In thousands*	2011		2010		2009
Domestic	$	161,108	$	113,430	$	105,122
Foreign		94,206		73,397		58,237

Income from operations	$	255,314	$	186,827	$	163,359

Undistributed earnings of the Company's foreign subsidiaries amounted to approximately $303.0 million at December 31, 2011. Those earnings are considered to be indefinitely reinvested; accordingly, no provision for U.S. federal and state income taxes has been provided thereon. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with its hypothetical calculation. Withholding taxes of approximately $3.2 million would be payable upon remittance of all previously unremitted earnings at December 31, 2011.

The consolidated provision for income taxes included in the Statement of Income consisted of the following:


	For the year ended December 31,
*In thousands*	2011			2010		2009
Current taxes
Federal	$	57,272		$	24,570	$	19,174
State		12,203			3,671		3,625
Foreign		32,285			19,239		18,114

	$	101,760		$	47,480	$	40,913
Deferred taxes
Federal		(10,591	)		11,205		6,426
State		(2,326	)		1,163		1,485
Foreign		(3,678	)		3,880		(520	)

		(16,595	)		16,248		7,391

Total provision	$	85,165		$	63,728	$	48,304

A reconciliation of the United States federal statutory income tax rate to the effective income tax rate on operations for the years ended December 31 is provided below:


	For the year ended December 31,
*In thousands*	2011			2010			2009
U. S. federal statutory rate		35.0	%		35.0	%		35.0	%
State taxes		2.3			2.0			2.2
Tax reserves		(0.5	)		0.2			(5.1	)
Foreign		(2.0	)		(1.9	)		(1.4	)
Research and development credit		(0.9	)		(1.0	)		(0.9	)
Other, net		(0.5	)		(0.2	)		(0.2	)

Effective rate		33.4	%		34.1	%		29.6	%

The effective income tax rate for 2011 included a net tax benefit of approximately $1.9 million which is due primarily to the settlement of examinations in various tax jurisdictions.

Deferred income taxes result from temporary differences in the recognition of income and expense for financial and income tax reporting purposes. These deferred income taxes will be recognized as future tax benefits or costs when the temporary differences reverse.

Components of deferred tax assets and liabilities were as follows:


	December 31,
*In thousands*	2011			2010
Deferred income tax assets:
Accrued expenses and reserves	$	30,602		$	10,035
Warranty reserve		13,144			11,832
Deferred comp/employee benefits		11,504			7,754
Pension and postretirement obligations		23,760			19,137
Inventory		9,518			7,461
State net operating loss		3,011			3,022
Tax credit carry forwards		4,635			4,795

Gross deferred income tax assets		96,174			64,036
Valuation allowance		—			(2,471	)

Total deferred income tax assets		96,174			61,565
Deferred income tax liabilities:
Property, plant & equipment		23,018			21,090
Intangibles		87,784			70,937
Other		2,010			3,124

Total deferred income tax liabilities		112,812			95,151

Net deferred income tax liability	$	(16,638	)	$	(33,586	)

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. In 2011, a $2.5 million valuation allowance for foreign tax credit carryforwards was released because the related foreign withholding taxes have been claimed as U.S. tax deductions rather than carried forward as a deferred tax asset.

Federal Research and Development credits of approximately $1.5 million have been fully utilized in 2011. Other state and foreign tax credit carryforwards of approximately $4.6 million are set to expire in various periods from 2013 to 2028. State net operating loss carryforwards in the amount of $64.5 million are set to expire in various periods from 2013 to 2032.

As of December 31, 2011, the liability for income taxes associated with uncertain tax positions was $8.2 million, of which $2.1 million, if recognized, would favorably affect the Company's effective income tax rate. As of December 31, 2010, the liability for income taxes associated with uncertain tax positions was $10.0 million, of which $3.1 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 uncertain tax positions follows:


*In thousands*	2011			2010			2009
Gross liability for uncertain tax positions at beginning of year	$	9,974		$	9,981		$	17,102
Gross increases—uncertain tax positions in prior periods		859			2,117			655
Gross decreases—uncertain tax positions in prior periods		—			(1,564	)		(562	)
Gross increases—current period uncertain tax positions		375			313			1,661
Gross decreases—audit settlements during year		(1,889	)		(751	)		(8,753	)
Gross decreases—expiration of audit statute of limitations		(1,115	)		(122	)		(122	)

Gross liability for uncertain tax positions at end of year	$	8,204		$	9,974		$	9,981

The Company includes interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2011, the total interest and penalties accrued was approximately $2.8 million and $1.5 million, respectively. As of December 31, 2010, the total interest and penalties accrued was approximately $3.1 million and $1.7 million, respectively.

The Internal Revenue Service is currently auditing the 2009 and 2010 tax years. With limited exception, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for years before 2008.

At this time, the Company believes that it is reasonably possible that unrecognized tax benefits of approximately $1.8 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.

STOCK-BASED COMPENSATION PLANS

As of December 31, 2011, the Company maintains employee stock-based compensation plans for stock options, restricted stock, 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 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). As of December 31, 2011, the number of shares available for future grants under the 2000 Plan was 453,322 shares. No awards may be made under the 2000 Plan or the Directors Plan subsequent to October 31, 2016. The 2011 Plan has a 10 year term through March 27, 2021 and provides a maximum of 1,900,000 shares for grants or awards.

Stock-based compensation expense was $18.6 million, $11.8 million and $3.6 million for the years ended December 31, 2011, 2010 and 2009, respectively. The Company recognized associated tax benefits related to the stock-based compensation plans of $5.1 million, $3.0 million and $1.6 million for the respective periods. Included in the stock-based compensation expense for 2011 above is $2.7 million of expense related to stock options, $4.4 million related to non-vested restricted stock, $10.6 million related to incentive stock awards and $900,000 related to awards issued for Directors' fees. At December 31, 2011, unamortized compensation expense related to those stock options, non-vested restricted shares and incentive stock awards expected to vest totaled $20.9 million and will be recognized over a weighted average period of 1.3 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 Directors Plan, as amended, authorizes a total of 500,000 shares of Common Stock to be issued. Generally, options issued under the plan 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. In addition, as compensation for directors' fees, a total of 13,500 shares have been awarded to non-employee directors for the year ended December 31, 2009. As compensation for directors' fees for the years ended December 31, 2011 and 2010, the Company issued a total of 11,636 and 18,302 shares of restricted stock to non-employee directors. The total number of shares issued under the plan as of December 31, 2011 was 391,938 shares.

The following table summarizes the Company's stock option activity and related information for the 2011 Plan, the 2000 Plan and Directors Plan for the years ended December 31:


	Options			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life		Aggregate intrinsic value (in thousands)

Exercisable at December 31, 2011		456,871		$	28.94		5.9	$	18,737

Options outstanding at December 31, 2011 were as follows:


Range of Exercise Prices	Number of Options Outstanding		Weighted Average Exercise Price of Options Outstanding		Weighted Average Remaining Contractual Life		Number of Options Currently Exercisable		Weighted Average Exercise Price of Options Currently Exercisable
Under $13.00		56,449	$	11.10		1.0		56,449	$	11.10

		862,392	$	34.74				456,871	$	28.94

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,
	2011			2010			2009
Dividend yield		.08	%		.10	%		.13	%
Risk-free interest rate		3.0	%		3.2	%		2.1	%
Stock price volatility		45.6			46.1			43.1
Expected life (years)		5.0			5.0			5.0
Weighted average fair value of options granted during the year	$	23.20		$	15.69		$	11.30

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 year 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 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. The incentive stock awards included in the table below represent the number of shares that may vest if the performance targets are met. As of December 31, 2011, based on the Company's performance, we estimate that these stock awards will vest and have recorded compensation expense accordingly. If our estimate of the number of these stock awards expected to vest changes in a future accounting period, compensation expense could be reduced and will be recognized over the remaining vesting period.

The following table summarizes the restricted stock activity for the 2011Plan, 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 years ended December 31:

Fair Value Measurement

FAIR VALUE MEASUREMENT

ASC 820 "Fair Value Measurements and Disclosures" defines fair value, establishes a framework for measuring fair value and explains the related disclosure requirements. ASC 820 indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.

Valuation Hierarchy. ASC 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value. A financial asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following table provides the liabilities carried at fair value measured on a recurring basis as of December 31, 2011, which are included in other current liabilities on the Condensed Consolidated Balance sheet:


	Total Carrying Value at December 31, 2011		Fair Value Measurements at December 31, 2011 Using
*In thousands*	Total Carrying Value at December 31, 2011		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Interest rate swap agreements		1,442		—		1,442		—

Total	$	1,442	$	—	$	1,442	$	—

The following table provides the liabilities carried at fair value measured on a recurring basis as of December 31, 2010, which are included in other current liabilities on the Condensed Consolidated Balance sheet:


	Total Carrying Value at December 31, 2010		Fair Value Measurements at December 31, 2010 Using
*In thousands*	Total Carrying Value at December 31, 2010		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Foreign currency forward contracts	$	192	$	—	$	192	$	—
Interest rate swap agreements		2,538		—		2,538		—

Total	$	2,730	$	—	$	2,730	$	—

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 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 (See Note 9 "Employee Benefit Plans" included herein).

- Definition

Tabular disclosure of the fair value measurement of assets and liabilities which includes [financial] instruments measured at fair value that are classified in stockholders' equity. Such assets and liabilities may be measured on a recurring or nonrecurring basis. The disclosures which may be required or desired include: (1) for assets and liabilities measured on a recurring basis, disclosure may include: (a) the fair value measurements at the reporting date; (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3); (c) for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (i) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets), and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (ii) purchases, sales, issuances, and settlements (net); (iii) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs); (d) the amount of the total gains or losses for the period in subparagraph (c) (i) above included in earnings (or changes in net assets) that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date and a description of where those unrealized gains or losses are reported in the statement of income (or activities); (e) the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period and (2) for assets and liabilities that are measured at fair value on a nonrecurring basis (for example, impaired assets) disclosure may include, in addition to (a) above: (a) the reasons for the fair value measurements recorded; (b) the same as (b) above; (c) for fair value measurements using significant unobservable inputs (Level 3), a description of the inputs and the information used to develop the inputs; and (d) the valuation technique(s) used to measure fair value and a discussion of changes, if any, in the valuation technique(s) used to measure similar assets and/or liabilities in prior periods. Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.

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 October 18, 2007, Faiveley Transport Malmo AB ("Faiveley Malmo") filed a request for arbitration with the International Chamber of Commerce alleging breach of contract and trade secret violations relating to the Company's manufacture and sale of certain components. In the international arbitration proceeding, Faiveley Malmo originally alleged $128 million in damages, but later reduced its claim to $91 million in damages. An ICC International Court of Arbitration Arbitral Tribunal heard the case during the first half of 2009 and issued an award dated December 21, 2009. Pursuant to the Award, the Company was required to make a $3.9 million royalty payment to Faiveley Malmo, with respect to Faiveley Malmo's claims against the Company alleging breach of contract and trade secret violations. On May 14, 2010, Faiveley Transport USA, Inc., Faiveley Transport Nordic AB, Faiveley Transport Amiens S.A.S, and Ellcon National, Inc. filed a complaint against Wabtec Corporation in the U.S. District Court for the Southern District of New York. That complaint was amended on June 8, 2010. The claims in the amended complaint include misappropriation of trade secrets, unfair competition, tortious interference with prospective business relations, tortious interference with prospective economic advantage, and unjust enrichment. On April 13, 2011, a judge issued an order, without an opinion, that granted the plaintiffs' motion for partial summary judgment on three of their four claims and denied Wabtec's motion for summary judgment. A jury trial on damages took place from June 20, 2011 to June 28, 2011, and the jury awarded the plaintiffs $18.1 million. On July 29, 2011, after considering post-trial motions on prejudgment interest and on potential adjustments to the jury's award, the Court entered a final verdict in the amount of $18.1 million, plus interest. The Company appealed the verdict, and this appeal is pending. The Company recorded a charge in the second quarter in the amount of $18.1 million.

The Company and a wholly owned subsidiary, Standard Car Truck Company ("SCTC"), were sued for patent infringement by Amsted Industries Incorporated ("Amsted") in the U.S. District Court for the Southern District of Illinois. Amsted did not allege any specific amount of damages. The Company moved to dismiss Amsted's amended complaint. SCTC answered Amsted's amended complaint, asserting defenses and counterclaims including non-infringement, patent invalidity, and unreasonable delays in pursuing the claim. SCTC also moved to transfer the case to the U.S. District Court for the Northern District of Illinois. The parties entered into a settlement agreement resolving this matter effective February 17, 2012. The Company does not believe that the settlement will have a material effect on the Company.

The Company is subject to a RCRA Part B Closure Permit ("the Permit") issued by the Environmental Protection Agency (EPA) and the Idaho Department of Health and Welfare, Division of Environmental Quality relating to the monitoring and treatment of groundwater contamination on, and adjacent to, the MotivePower Inc. (Boise, Idaho) facility. In compliance with the Permit, the Company has completed an accelerated plan for the treatment of contaminated groundwater, and continues onsite and offsite monitoring for hazardous constituents. Reflected in the commitments and contingencies line of the consolidated balance sheet, the Company has accruals of approximately $501,000 at December 31, 2011, the estimated remaining costs for remediation and monitoring. The Company was in compliance with the Permit at December 31, 2011.

Foster Wheeler Energy Corporation (FWEC), the seller of the Mountaintop, Pennsylvania property to the predecessor of one of the Company's subsidiaries in 1989, agreed to indemnify the Company's predecessor and its successors and assigns against certain identified environmental liabilities for which FWEC executed a Consent Order Agreement with the Pennsylvania Department of Environmental Protection (PADEP) and EPA. Management believes that this indemnification arrangement is enforceable for the benefit of the Company and that FWEC has the financial resources to honor its obligations under this indemnification arrangement.

Young Radiator ceased manufacturing operations at its Racine, Wisconsin facility in the early 1990s. Investigations prior to the acquisition of Young revealed some levels of contamination on the Racine property. The Company has completed a comprehensive site evaluation and implemented a groundwater remediation program under Wisconsin's voluntary remediation program. Site monitoring is being conducted to demonstrate attainment of Wisconsin's cleanup requirements. The Company believes the regulating authority is generally in agreement with the selected remediation approach and findings presented to-date.

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 Information

SEGMENT INFORMATION

Wabtec has two reportable segments—the Freight Group and the Transit Group. 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 Group 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 Group primarily manufactures and services components for new and existing passenger transit vehicles, typically subway cars and buses, builds new commuter locomotives 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.

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
Summary Of Significant Accounting Policies (Policy)	Dec. 31, 2011
Summary Of Significant Accounting Policies [Abstract]
Principles Of Consolidation	*Principles of Consolidation* The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. Such statements have been prepared in accordance with 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 $8.4 million and $7.5 million as of December 31, 2011 and 2010, 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 provides for 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.
Intangible Assets	*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 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. In September 2011, the FASB issued Accounting Standards Updated ("ASU") 2011-08 which amends the rules for testing goodwill for impairment. Under the new rules, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. We adopted ASU 2011-08 for our 2011 annual goodwill impairment test. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we assess relevant events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit's fair value or carrying amount involve significant judgments and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Wabtec specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. If our qualitative assessment concludes that it is probable that we have an impairment, the Company then performs a quantitative assessment. 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 Company reviews goodwill for impairment at the reporting unit level. The Company prepares its goodwill impairment analysis by comparing the estimated fair value of each reporting unit, using an income approach (a discounted cash flow model) as well as a market approach, with its carrying value. The income approach and the market approach are equally weighted in arriving at fair value, which the Company has applied consistently. The discounted cash flow model requires several assumptions including future sales growth, EBIT (earnings before interest and taxes) margins and capital expenditures for the reporting units. The discounted cash flow model also requires the use of a discount rate and a terminal revenue growth rate (the revenue growth rate for the period beyond the three 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.
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 $19.9 million, $22.8 million and $20.4 million for 2011, 2010 and 2009, respectively. Accrued warranty was $50.6 million and $35.5 million at December 31, 2011 and 2010, 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* The Company has entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. 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. At December 31, 2011, the Company had no forward contracts. At December 31, 2010, the Company had forward contracts for the sale of South African Rand (ZAR) and the purchase of U.S. Dollars (USD). The Company concluded that these foreign currency forward contracts qualify for cash flow hedge accounting which permits the recording of the fair value of the forward contract and corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. As of December 31, 2010, the Company had forward contracts with a notional value of 24.7million ZAR (or $3.4 million U.S.) with an average exchange rate of 7.19 ZAR per $1 USD, resulting in the recording of a current liability of $192,000 and a corresponding offset in accumulated other comprehensive income of $122,000, net of tax. To reduce the impact of interest rate changes on a portion of this variable-rate debt, the Company entered into interest rate swap agreements which effectively converted a portion of the debt from a variable to a fixed-rate borrowing during the term of the swap contract. 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 agreements qualify for special cash flow hedge accounting which permits the recording of the fair value of the interest rate swap agreement and corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. As of December 31, 2011, the Company had interest rate swap agreements with a notional value of $107.0 million and which effectively changed the Company's interest rate on bank debt at December 31, 2011 from a variable rate to a fixed rate of 2.19%. The interest rate swap agreements mature on December 31, 2012. As of December 31, 2011, the Company recorded a current liability of $1.4 million and a corresponding offset in accumulated other comprehensive loss of $0.9 million, net of tax.
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 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 acumulated 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 $2.0 million, $1.0 million and $1.3 million for 2011, 2010 and 2009, 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, 2011 and 2010. Net income attributable to noncontrolling interests for the years ended December 31, 2011, 2010 and 2009 was not material.
Other Comprehensive Income (Loss)	*Other Comprehensive Income (Loss)* Comprehensive income (loss) is defined as net income and all other non-owner changes in shareholders' equity. The Company's accumulated other comprehensive income consists of foreign currency translation adjustments, foreign currency hedges, foreign exchange contracts, interest rate swaps, and pension and post retirement related adjustments.

Provisions are made currently for estimated losses on uncompleted contracts. 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.

- Definition

Tabular disclosure of liabilities, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, by class that are measured at fair value on a recurring basis. The disclosures contemplated herein include the fair value measurements at the reporting date by the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
