- 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).

Stock-Based Compensation [Abstract]

Stock-Based Compensation

8. STOCK-BASED COMPENSATION

As of March 31, 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 $5.1 million and $3.4 million for the three months ended March 31, 2012 and 2011, respectively. Included in the stock-based compensation expense for 2012 above is $0.6 million of expense related to stock options, $1.0 million related to restricted stock, $69,000 related to restricted units, $3.2 million related to incentive stock awards and $225,000 related to awards issued for Directors' fees. At March 31, 2012, unamortized compensation expense related to stock options, restricted stock and incentive stock awards expected to vest totaled $32.0 million and will be recognized over a weighted average period of 1.8 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 three months ended March 31, 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		71,898			70.55				347
Exercised		(38,876	)		25.88				(1,924	)
Canceled		(23,861	)		33.70				(994	)

Outstanding at March 31, 2012		871,553		$	38.12		6.6	$	32,464

Exercisable at March 31, 2012		582,043		$	31.37		6.3	$	25,611

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:


	Three months ended March 31,
	2012			2011
Dividend yield		.17	%		.07	%
Risk-free interest rate		1.35	%		3.03	%
Stock price volatility		45.0	%		45.6	%
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 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 March 31, 2012, 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 or increased and will be recognized over 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 three months ended March 31, 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		90,203			118,660			70.56
Vested		(85,808	)		(122,079	)		33.76
Canceled		(11,402	)		12,583			4.14

Outstanding at March 31, 2012		267,602			655,526		$	52.31

Accounting Policies [Abstract]

Basis Of Presentation

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

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

The notes included herein should be read in conjunction with the audited consolidated financial statements included in Wabtec's Annual Report on Form 10-K for the year ended December 31, 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 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.

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 $16.8 million and $15.4 million at March 31, 2012 and December 31, 2011, respectively.

Use Of Estimates

Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates. On an ongoing basis, management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.

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 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 March 31, 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 March 31, 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 March 31, 2012 from a variable rate to a fixed rate of 2.08%. The interest rate swap agreements mature at various times through November 2016. As of March 31, 2012, the Company has recorded a current liability of $1.2 million and a corresponding offset in accumulated other comprehensive loss of $0.7 million, net of tax, related to these agreements.

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 a margin.

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 $410,000 and $323,000 for the three months ended March 31, 2012 and 2011, respectively.

Non-Controlling Interests

Non-controlling Interests In accordance with ASC 810, the Company has classified non-controlling interests as equity on our condensed consolidated balance sheets as of March 31, 2012 and December 31, 2011. Net income attributable to non-controlling interests for the three months ended March 31, 2012 and 2011 was not material.

Other Comprehensive Income

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 $2.0 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 March 31, 2012, the Company had available bank borrowing capacity of approximately $313.8 million, net of $51.2 million of letters of credit, 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 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 March 31, 2012 the weighted average interest rate on the Company's variable rate debt was 1.51%. 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 March 31, 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 March 31, 2012 from a variable rate to a fixed rate of 2.08%. 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.

Also, the Company entered into a forward starting interest rate swap agreement with a notional value of $150 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 a margin.

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 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.

Segment Information [Abstract]

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.

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.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	13. COMMITMENTS AND CONTINGENCIES Claims have been filed against the Company and certain of its affiliates in various jurisdictions across the United States by persons alleging bodily injury as a result of exposure to asbestos-containing products. 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 under which the Company was required to make a $3.9 million royalty payment to Faiveley Malmo. 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, which was later amended, against Wabtec Corporation in the U.S. District Court for the Southern District of New York alleging 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; a jury trial on damages took place in June 2011, and the jury awarded the plaintiffs $18.1 million. On July 29, 2011, 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 the verdict amount in the second quarter of 2011. The Company is subject to a number of other commitments and contingencies as described in its Annual Report on Form 10-K for the year ended December 31, 2011, filed on February 24, 2012. During the first three months of 2012, there were no material changes other than what is discussed above to the information described in Note 18 therein.

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.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2012
Income Taxes [Abstract]
Income Taxes	9. INCOME TAXES The overall effective income tax rate was 34.4% and 35.2% for the three months ended March 31, 2012 and 2011, respectively. The decrease in the effective tax rate is due to a $0.4 million deferred tax valuation allowance recorded in the first quarter of 2011 because of the uncertainty of the realization of certain deferred tax assets. As of March 31, 2012, the liability for income taxes associated with uncertain tax positions is $8.2 million, of which $2.1 million, if recognized would favorably affect the Company's effective tax rate. As of December 31, 2011 these amounts were the same. The Company includes interest and penalties related to uncertain tax positions in income tax expense. As of March 31, 2012 the total accrued interest and penalties are $3.0 million and $1.6 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 $1.8 million may change within the next 12 months due to the expiration of statutory review periods and current examinations.

- Definition

The entire disclosure for income taxes. 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.

Fair Value Measurement [Abstract]

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 March 31, 2012, which are included in other current liabilities on the Condensed Consolidated Balance sheet:


	Total Carrying Value at March 31, 2012		Fair Value Measurements at March 31, 2012 Using
*In thousands*	Total Carrying Value at March 31, 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		1,225		—		1,225		—

Total	$	1,225	$	—	$	1,225	$	—

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

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.
