- Definition

The change in equity [net assets] of a business enterprise during a period from transactions and other events and circumstances from non-owner sources which are attributable to the reporting entity. It includes all changes in equity during a period except those resulting from investments by owners and distributions to owners, but excludes any and all transactions which are directly or indirectly attributable to that ownership interest in subsidiary equity which is not attributable to the parent.

+ References + Details

- Definition

The aggregate unrealized foreign currency transaction gain (loss) (pretax) included in determining net income for the reporting period. Represents the aggregate of gains (losses) on transactions that are unsettled as of the balance sheet date, which is therefore an adjustment to reconcile income (loss) from continuing operations to net cash provided by or used in continuing operations. Excludes foreign currency transactions designated as hedges of net investment in a foreign entity and intercompany foreign currency transactions that are of a long-term nature, when the entities to the transaction are consolidated, combined, or accounted for by the equity method in the reporting entity's financial statements. For certain entities, primarily banks, that are dealers in foreign exchange, foreign currency transaction gains (losses) may be disclosed as dealer gains (losses).

ACCOUNTING POLICIES

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, 2011. The December 31, 2011 information has been derived from the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

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 $95.3 million and $58.9, customer deposits were $84.1 million and $72.8, and provisions for loss contracts were $11.4 million and $9.3 million at June 30, 2012 and December 31, 2011, 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 $16.4 million and $15.4 million at June 30, 2012 and December 31, 2011, 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.

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 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 June 30, 2012, the Company had no forward contracts.

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. The Company is exposed to credit risk in the event of nonperformance by the counterparties. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparties are large financial institutions with excellent credit ratings and history of performance. The Company currently believes the risk of nonperformance is negligible. The Company concluded that these interest rate swap agreements qualify for cash flow hedge accounting which permits the recording of the fair value of the interest rate swap agreements and corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet.

Effective June 30, 2012, the Company had interest rate swap agreements with a notional amount of $107.0 million and which effectively changed the Company’s interest rate on bank debt at June 30, 2012 from a variable rate to a fixed rate of 1.81%. The interest rate swap agreements mature on December 31, 2012. As of June 30, 2012, the Company has recorded a current liability of $0.8 million and a corresponding offset in accumulated other comprehensive loss of $0.5 million, net of tax, related to these agreements.

Also, 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, the interest rate swap agreement will 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% plus the applicable borrowing margin. As of June 30, 2012, the Company has recorded a current liability of $2.8 million and a corresponding offset in accumulated other comprehensive loss of $1.7 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 gains recognized in other income (expense), net were $631,000 for the three months ended June 30, 2012. Foreign exchange transaction losses recognized in other income (expense), net were $589,000 for the three months ended June 30, 2011. Foreign exchange transaction gains recognized in other income (expense), net were $1.0 million for the six months ended June 30, 2012. Foreign exchange transaction losses recognized in other income (expense), net were $266,000 for the six months ended June 30, 2011.

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 June 30, 2012 and December 31, 2011. Net income attributable to non-controlling interests for the three and six months ended June 30, 2012 and 2011 was not material.

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

The components of accumulated other comprehensive loss were:


*In thousands*	June 30, 2012			December 31, 2011
Foreign currency translation loss	$	(8,065	)	$	(2,447	)

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 and an additional 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 June 30, 2012 the weighted average interest rate on the Company’s variable rate debt was 1.25%. 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 June 30, 2012, 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 June 30, 2012 from a variable rate to a fixed rate of 1.81%. The interest rate swap agreements mature on December 31, 2012. The Company is exposed to credit risk in the event of nonperformance by the counterparties. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparties are large financial institutions with excellent credit ratings and history of performance. The Company currently believes the risk of nonperformance is negligible.

The 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.

6.875% Senior Notes Due August 2013

In August 2003, the Company issued $150.0 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 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.

STOCK-BASED COMPENSATION

6 Months Ended

Jun. 30, 2012

STOCK-BASED COMPENSATION

8. STOCK-BASED COMPENSATION

As of June 30, 2012, 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 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. 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 $10.1 million and $9.4 million for the six months ended June 30, 2012 and 2011, respectively. Included in the stock-based compensation expense for 2012 above is $1.3 million of expense related to stock options, $2.4 million related to restricted stock, $377,000 related to restricted units, $5.6 million related to incentive stock awards and $400,000 related to awards issued for Directors’ fees. At June 30, 2012, unamortized compensation expense related to stock options, restricted stock, restricted units and incentive stock awards expected to vest totaled $28.2 million and will be recognized over a weighted average period of 1.5 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. Under the Directors Plan, options become exercisable over a three-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 six months ended June 30, 2012:


	Options			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life		Aggregate intrinsic value (in thousands)
Outstanding at December 31, 2011		862,392		$	34.74		6.5	$	30,362
Granted		74,698			70.63				551
Exercised		(58,883	)		24.88				(3,128	)
Canceled		(26,717	)		34.46				(1,164	)

Outstanding at June 30, 2012		851,490		$	38.58		6.4	$	33,572

Exercisable at June 30, 2012		562,786		$	31.69		6.1	$	26,070

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:


	Six months ended June 30,
	2012			2011
Dividend yield		.23	%		.07	%
Risk-free interest rate		1.34	%		3.03	%
Stock price volatility		44.95	%		45.58	%
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 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 annually issued incentive stock awards to eligible employees that vest, upon attainment of certain 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 June 30, 2012, the Company estimates that it will achieve 200%, 200% and 100% for the incentive stock awards expected to vest based on performance for the three year periods ending December 31, 2012, 2013, and 2014, 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 six months ended June 30, 2012:


	Restricted Stock and Units			Incentive Stock Awards			Weighted Average Grant Date Fair Value
Outstanding at December 31, 2011		274,609			646,362		$	44.04
Granted		105,647			118,660			70.71
Vested		(97,694	)		(122,079	)		35.63
Adjustment for incentive stock awards expected to vest		—			14,802			42.96
Canceled		(13,008	)		(2,219	)		39.72

Outstanding at June 30, 2012		269,554			655,526		$	52.46

- Definition

Tabular disclosure of components of a stock option or other award plan under which equity-based compensation is awarded to employees, typically comprised of the amount of unearned compensation (deferred compensation cost), compensation expense, and changes in the quantity and fair value of the shares (or other type of equity) granted, exercised, forfeited, and issued and outstanding pertaining to that plan. Disclosure may also include nature and general terms of such arrangements that existed during the period and potential effects of those arrangements on shareholders, effect of compensation cost arising from equity-based payment arrangements on the income statement, method of estimating the fair value of the goods or services received, or the fair value of the equity instruments granted, during the period, cash flow effects resulting from equity-based payment arrangements and, for registrants that accelerate vesting of out of the money share options, reasons for the decision to accelerate.

INCOME TAXES

6 Months Ended

Jun. 30, 2012

INCOME TAXES

9. INCOME TAXES

The overall effective income tax rate was 33.7% and 34.0% for the three and six months ended June 30, 2012, respectively, and 30.3% and 33.0% for the three and six months ended June 30, 2011, respectively. The increase in the effective tax rate is due to a $1.7 million benefit recorded in the second quarter of 2011 relating to settlements with taxing authorities and the expiration of statutory review periods in various jurisdictions.

As of June 30, 2012, the liability for income taxes associated with uncertain tax positions is $7.5 million, of which $1.6 million, if recognized would favorably affect the Company’s effective tax rate. As of December 31, 2011 the liability associated with uncertain tax positions was $8.2 million, of which $2.1 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 June 30, 2012 the total accrued interest and penalties are $2.3 million and $1.2 million, respectively. As of December 31, 2011 the total accrued interest and penalties were $2.8 million and $1.5 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 2009.

At this time, the Company believes that it is reasonably possible that unrecognized tax benefits of approximately $0.1 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.

- Definition

Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Percentage allocated to common shareholders		99.5	%		99.5	%

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

FAIR VALUE MEASUREMENT

12. 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 June 30, 2012, which are included in other current liabilities on the Condensed Consolidated Balance sheet:


	Total Carrying Value at June 30, 2012		Fair Value Measurements at June 30, 2012 Using
*In thousands*	Total Carrying Value at June 30, 2012		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		3,603		—		3,603		—

Total	$	3,603	$	—	$	3,603	$	—

The following table provides the liabilities carried at fair value measured on a recurring basis as of December 31, 2011, which is 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)

- Definition

The entire disclosure of the fair value measurement of assets and liabilities, which includes financial instruments measured at fair value that are classified in shareholders' equity, which may be measured on a recurring or nonrecurring basis.

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.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.

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.
