Description Of The Business [Abstract]

Description Of The Business

1.	DESCRIPTION OF THE BUSINESS

Description of the Business—TransDigm Group Incorporated ("TD Group"), through its wholly-owned subsidiary, TransDigm Inc., is a leading global designer, producer and supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft in service today. TransDigm Inc. along with TransDigm Inc.'s direct and indirect wholly-owned operating subsidiaries (collectively, with TD Group, the "Company" or "TransDigm"), offers a broad range of proprietary aerospace components. TD Group has no significant assets or operations other than its 100% ownership of TransDigm Inc. TD Group's common stock is listed on The New York Stock Exchange, or the NYSE, under the trading symbol "TDG."

Major product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, NiCad batteries and chargers, engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, cockpit security components and systems, specialized cockpit displays, aircraft audio systems, specialized lavatory components, engineered interior surfaces and lighting and control technology.

Separate Financial Statements—Separate financial statements of TransDigm Inc. are not presented because TransDigm Inc.'s 7³/4% senior subordinated notes are fully and unconditionally guaranteed on a senior subordinated basis by TD Group and all existing domestic subsidiaries of TransDigm Inc. and because TD Group has no significant operations or assets separate from its investment in TransDigm Inc.

Acquisitions [Abstract]

Acquisitions

2.	ACQUISITIONS

Schneller Holdings—On August 31, 2011, TransDigm Inc. acquired all of the outstanding equity interests in Schneller Holdings LLC ("Schneller") for approximately $288.5 million in cash, subject to adjustments based on the level of working capital as of the closing date of the acquisition. Schneller designs and manufactures proprietary, highly engineered laminates, thermoplastics, and non-textile flooring for use primarily on side walls, lavatories, galleys, bulkheads and cabin floors for commercial aircraft. These products fit well with TransDigm's overall business direction. The Company expects that the approximately $195 million of goodwill recognized for the acquisition will be deductible for tax purposes.

Talley Actuation—On December 31, 2010, AeroControlex Group, Inc., a wholly owned subsidiary of TransDigm Inc., acquired the actuation business of Telair International Inc. ("Talley Actuation"), a wholly-owned subsidiary of Teleflex Incorporated, for approximately $93.6 million in cash, which includes a purchase price adjustment of $0.3 million received in the third quarter of fiscal 2011. Talley Actuation manufactures proprietary, highly engineered electro-mechanical products and other components for commercial and military aircraft. These products fit well with TransDigm's overall business direction. The Company expects that the approximately $70 million of goodwill recognized for the acquisition will be deductible for tax purposes.

McKechnie Aerospace Holdings, Inc.—On December 6, 2010, TransDigm Inc. acquired all of the outstanding stock of McKechnie Aerospace Holdings Inc. ("McKechnie Aerospace"), for approximately $1.27 billion in cash, which includes a purchase price adjustment of $0.3 million paid in the third quarter of fiscal 2011. McKechnie Aerospace, through its subsidiaries, is a leading global designer, producer and supplier of aerospace components, assemblies and subsystems for commercial aircraft, regional/business jets, military fixed wing and rotorcraft. Some of the businesses acquired as part of McKechnie Aerospace have been divested. See Note 21 to the Consolidated Financial Statements. The remaining products fit well with TransDigm's overall business direction.

The Company financed the McKechnie Aerospace acquisition, repaid borrowings under the previous senior secured credit facility and redeemed outstanding 7³/4% Senior Subordinated Notes due 2014 through a combination of the offering of $1.60 billion of 7³/4% Senior Subordinated Notes due 2018 and new term loan borrowings of $1.55 billion due 2017. See Note 11 to the Consolidated Financial Statements.

The total purchase price was allocated to the underlying assets acquired and liabilities assumed based upon management's estimated fair values at the date of acquisition. The consolidated balance sheet at September 30, 2011 reflects the preliminary purchase price allocation for the business; therefore, the values attributed to the assets acquired and liabilities assumed in the consolidated financial statements are subject to adjustment. To the extent the purchase price exceeded the estimated fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill.

The following table summarizes the preliminary purchase price allocation of the estimated fair values of the assets acquired and liabilities assumed at the transaction date (in thousands).


Assets acquired:
Current assets, excluding cash acquired	$	109,305
Property, plant and equipment		48,997
Intangible assets		433,000
Goodwill		864,004

Total assets acquired	$	1,455,306

Liabilities assumed:
Current liabilities	$	42,186
Deferred tax liabilities		115,591
Other noncurrent liabilities		31,837

Total liabilities assumed	$	189,614

Net assets acquired	$	1,265,692

The Company expects that the approximately $864.0 million of goodwill recognized for the acquisition will not be deductible for tax purposes.

The results of operations of McKechnie Aerospace are included in the Company's consolidated financial statements from the date of the transaction. The Company recorded net sales of $212.2 million from the date of acquisition through September 30, 2011. It is impracticable to determine a meaningful measure of the earnings of the acquired business from the date of acquisition through September 30, 2011 because certain McKechnie Aerospace plant facilities have been integrated into other TransDigm operations. Had the McKechnie acquisition and related financing transactions occurred at the beginning of the fiscal year ended September 30, 2010, unaudited pro forma consolidated results for the years ended September 30, 2011 and 2010 would have been as follows (in thousands, except per share data):


	Fiscal Years Ended September 30,
	2011		2010
Net sales	$	1,247,386	$	1,033,059

Net income applicable to common stock from continuing operations	$	217,575	$	44,614

Net earnings per share from continuing operations:
Basic and diluted	$	4.08	$	0.84

The unaudited pro forma consolidated results are based on the Company's historical financial statements and those of McKechnie Aerospace and do not necessarily indicate the results of operations that would have resulted had the acquisition actually been completed at the beginning of the applicable period presented. The pro forma financial information assumes that the companies were combined as of October 1, 2009. The pro forma results for the fiscal year ended September 30, 2010 reflect the business combination accounting effects from the acquisition including amortization charges from the acquired intangible assets, inventory purchase accounting adjustments charged to cost of sales as the inventory is sold, increase in interest expense associated with debt incurred to fund the acquisition, refinancing costs associated with the refinancing of the Company's entire debt structure and acquisition-related transaction costs. The unaudited pro forma consolidated results do not give effect to the synergies of the acquisition and are not indicative of the results of operations in future periods.

Semco Instruments—On September 3, 2010, TransDigm Inc. completed the acquisition of Semco Instruments, Inc. ("Semco Instruments") for approximately $73.6 million in cash, which includes a purchase price adjustment of $3.0 million paid in the first quarter of fiscal 2011. Semco Instruments manufactures proprietary, highly engineered components for major turbo-prop, turbo-fan, and turbo-shaft engines, which are primarily used on helicopters, business jets and selected regional airplanes. These products fit well with TransDigm's overall business direction. The Company expects that the approximately $41 million of goodwill recognized for the acquisition will not be deductible for tax purposes.

Dukes Aerospace—On December 2, 2009, Dukes Aerospace, Inc., a newly formed, wholly owned subsidiary of TransDigm Inc., acquired substantially all of the aerospace related assets and certain liabilities from Dukes, Inc. and GST Industries, Inc. (collectively "Dukes Aerospace") for approximately $95.5 million in cash, which includes a purchase price adjustment of $0.2 million received in the third quarter of fiscal 2011. In addition, the agreement provides for potential earn-out payments up to a total of $60 million over four years based on the achievement of certain growth targets. The initial purchase price allocation included a fair value liability of $8.0 million recorded for the potential earn-out payments. During the third quarter of fiscal 2011, the Company reversed $3.0 million of the earn-out liability based on lower growth projections relative to the required growth targets for the last three years of the four-year earn-out arrangement. The reversal of earn-out liability is included in selling and administrative expenses in the consolidated statements of income for the fiscal year ended September 30, 2011. The Dukes Aerospace business supplies proprietary, highly engineered components primarily to the business jet, regional jet, and military aerospace markets, along with commercial and military helicopter markets. The products are comprised primarily of highly engineered valves and certain pumps, solenoids and related components. These products fit well with TransDigm's overall business direction. The Company expects that the approximately $64 million of goodwill recognized for the acquisition will be deductible for tax purposes.

Woodward HRT Product Line—On August 10, 2009, AeroControlex Group, Inc., a wholly owned subsidiary of TransDigm Inc., acquired certain product line assets of Woodward HRT, Inc., a subsidiary of Woodward Governor Company ("Woodward HRT product line") for approximately $48.7 million in cash, which includes a purchase price adjustment of $0.7 million paid in February 2010. The product line comprises a range of highly engineered fuel and pneumatic valves and surge suppressors, the majority of which are used on military rotary and fixed wing aircraft, all of which fit well with TransDigm's overall business direction. Woodward Governor recently acquired this business as part of its acquisition of HR Textron, Inc. The Company expects that the $27 million of goodwill recognized for the acquisition will be deductible for tax purposes.

Acme Aerospace—On July 24, 2009, TransDigm Inc. acquired all of the outstanding capital stock of Acme Aerospace, Inc. ("Acme") for approximately $40.9 million in cash, which includes a purchase price adjustment of $0.2 million paid in October 2009. Acme is a designer and manufacturer of proprietary, highly engineered components to the commercial aerospace industry, comprising primarily fibrous nickel cadmium main ship batteries, battery chargers, battery back-up systems and power conversion equipment. These products fit well with TransDigm's overall business direction. The Company expects that the $32 million of goodwill recognized for the acquisition will not be deductible for tax purposes.

Aircraft Parts Corporation—On December 16, 2008, TransDigm Inc. acquired all of the outstanding capital stock of Aircraft Parts Corporation ("APC") for approximately $66.9 million in cash, net of a purchase price adjustment of $0.7 million received in November 2009. APC is a designer and manufacturer of starter generators, generator control units and related components for turbine engines, all of which fit well with TransDigm's overall business direction. The Company expects that the $50 million of goodwill recognized for the acquisition will not be deductible for tax purposes.

The Company accounted for the acquisitions of McKechnie Aerospace, Schneller, Talley Actuation, Semco Instruments, Dukes Aerospace, the Woodward HRT product line, Acme and APC, (collectively, the "Acquisitions") using the acquisition method and included the results of operations of the Acquisitions in its consolidated financial statements from the effective date of each acquisition. The Company is in the process of obtaining a third-party valuation of certain tangible and intangible assets of Schneller and, therefore, the values attributed to those acquired assets in the consolidated financial statements are subject to adjustment. Pro forma net sales and results of operations for the acquisitions of Schneller, Talley Actuation, Semco Instruments, Dukes Aerospace, the Woodward HRT product line, Acme and APC had they occurred at the beginning of the applicable fiscal year ended September 30, 2011 or 2010, are not significant and, accordingly, are not provided.

The Acquisitions strengthen and expand the Company's position to design, produce and supply highly-engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies (obtaining profitable new business, improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for each acquisition reflects the current earnings before interest, taxes, depreciation and amortization (EBITDA) and cash flows, as well as, the future EBITDA and cash flows expected to be generated by the business, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 30 years.

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Summary Of Significant Accounting Policies

3.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Consolidation—The accompanying consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States ("GAAP") and include the accounts of TD Group and subsidiaries. All significant intercompany balances and transactions have been eliminated.

Revenue Recognition and Related Allowances—Revenue is recognized from the sale of products when title and risk of loss passes to the customer, which is generally at the time of shipment. Substantially all sales are made pursuant to firm, fixed-price purchase orders received from customers. Provisions for estimated returns, uncollectible accounts and the cost of repairs under contract warranty provisions are provided for in the same period as the related revenues are recorded and are principally based on historical results modified, as appropriate, by the most current information available. Due to uncertainties in the estimation process, it is possible that actual results may vary from the estimates.

Shipping and Handling Costs—All shipping and handling costs are included in cost of sales in the Consolidated Statements of Income.

Research and Development Costs—The Company expenses research and development costs as incurred and classifies such amounts in selling and administrative expenses. The expense recognized for research and development costs for the years ended September 30, 2011, 2010 and 2009 was approximately $19.3 million, $13.9 million, and $12.6 million, respectively.

Cash Equivalents —The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Allowance for Uncollectible Accounts—The Company reserves for amounts determined to be uncollectible based on specific identification of losses and estimated losses based on historical experience. The allowance also incorporates a provision for the estimated impact of disputes with customers. The determination of the amount of the allowance for doubtful accounts is subject to significant levels of judgment and estimation by management. If circumstances change or economic conditions deteriorate or improve, the allowance for doubtful accounts could increase or decrease.

Inventories—Inventories are stated at the lower of cost or market. Cost of inventories is determined by the average cost and the first-in, first-out (FIFO) methods for all locations except CEF Industries, Inc. which determines the cost of inventories using the last-in, first-out (LIFO) method. Approximately 5% of the inventory was valued under the LIFO method at September 30, 2011. Provision for potentially obsolete or slow-moving inventory is made based on management's analysis of inventory levels and future sales forecasts. In accordance with industry practice, all inventories are classified as current assets even though a portion of the inventories may not be sold within one year.

Property, Plant and Equipment—Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: land improvements from 10 to 20 years, buildings and improvements from 5 to 30 years, machinery and equipment from 2 to 10 years and furniture and fixtures from 3 to 10 years.

Property, plant and equipment is assessed for potential impairment whenever indicators of impairment are present by determining whether the carrying value of the property can be recovered through projected, undiscounted cash flows from future operations over the property's remaining estimated useful life. Any impairment recognized is the amount by which the carrying amount exceeds the fair value of the asset.

Debt Issue Costs, Premiums and Discounts—The cost of obtaining financing as well as premiums and discounts are amortized using the effective interest method over the terms of the respective obligations/securities.

Intangible Assets—Intangible assets consist of identifiable intangibles acquired or recognized in accounting for the acquisitions (trademarks, trade names, technology, order backlog and a license agreement) and goodwill. Goodwill and intangible assets that have indefinite useful lives (trademarks and trade names) are subject to annual impairment testing. Management determines fair value using a discounted future cash flow analysis or other accepted valuation techniques.

A two-step impairment test is used to identify potential goodwill impairment. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of a reporting unit (as defined) with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired, and the second step of the goodwill impairment test is unnecessary. The second step measures the amount of impairment, if any, by comparing the carrying value of the goodwill associated with a reporting unit to the implied fair value of the goodwill derived from the estimated overall fair value of the reporting unit and the individual fair values of the other assets and liabilities of the reporting unit.

GAAP requires that the annual, and any interim, impairment assessment be performed at the reporting unit level. The reporting unit level is the operating subsidiary level for the Company. Substantially all goodwill was determined and recognized for each operating subsidiary pursuant to the accounting for the merger or acquisition as of the date of each transaction, and therefore the allocation of goodwill among reporting units was immaterial for purposes of the impairment assessment. With respect to acquisitions integrated into an existing operating subsidiary, any related goodwill is combined with goodwill of the operating subsidiary.

The impairment test for indefinite lived intangible assets consists of a comparison between their fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their fair values, an impairment loss will be recognized in an amount equal to the sum of any such excesses.

The Company assesses the recoverability of its amortizable intangible assets only when indicators of impairment are present by determining whether the amortization over their remaining lives can be recovered through projected, undiscounted cash flows from future operations. Amortization of amortizable intangible assets is computed using the straight-line method over the following estimated useful lives: technology from 20 to 22 years, order backlog over one year, and a license agreement over 20 years.

Prior to fiscal 2010, the annual impairment test of goodwill and indefinite-lived intangible assets was performed as of the last day of our fourth quarter. During fiscal 2010, the measurement date was changed to the first day of the fourth fiscal quarter. As a result of our growth and increase in the number of reporting units, we believe the change in our measurement date is preferable in order to provide additional time to quantify the fair value of our reporting units and to evaluate the results of the impairment testing.

Stock Option Plans—The Company records stock-based compensation measured using the fair value method of accounting. Compensation expense is recorded over the vesting periods of the options.

Income Taxes—The Company accounts for income taxes using an asset and liability approach. Deferred taxes are recorded for the difference between the book and tax basis of various assets and liabilities. A valuation allowance is provided when it is more likely than not that some or all of a deferred tax asset will not be realized.

Contingencies—During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows. The Company believes that its potential exposure to such legal actions is adequately covered by its aviation product and general liability insurance.

Estimates—The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Comprehensive Income (Loss)—The term "comprehensive income (loss)" represents the change in stockholders' equity from transactions and other events and circumstances resulting from non-stockholder sources. The Company's accumulated other comprehensive income or loss, consisting principally of fair value adjustments to its interest rate swaps (net of tax), cumulative foreign currency translation adjustments and pension liability adjustments (net of tax), is reported separately in the accompanying consolidated statements of changes in stockholders' equity. See Note 20 to the Consolidated Financial Statements.

Segment Reporting—Management evaluates the Company as one reporting segment in the aerospace industry. The Company is engaged in the design, manufacture and sale of highly engineered aircraft components used in aerospace and defense applications through its wholly-owned subsidiaries. Substantially all of the Company's operations are located within the United States.

Earnings per Share—Earnings per share information is determined using the two-class method, which includes the weighted-average number of common shares outstanding during the period and other securities that participate in dividends ("participating securities"). Our vested stock options are considered "participating securities" because they include non-forfeitable rights to dividends. In applying the two-class method, earnings are allocated to both common stock shares and participating securities based on their respective weighted-average shares outstanding for the period. Diluted earnings per share information may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated using the treasury stock method.

4.	RECENT ACCOUNTING PRONOUNCEMENTS

In May 2011, the Financial Accounting Standard Board ("FASB") issued authoritative accounting guidance included in Accounting Standards Codification (ASC) Topic 820, "Fair Value Measurement." This guidance amends the requirements for measuring fair value and disclosing information about fair value measurements and is effective for the Company during the first quarter of fiscal 2012. Upon adoption, the Company does not expect this standard to have a material impact on its financial condition or results of operations.

In June 2011, the FASB issued authoritative accounting guidance included in ASC Topic 220, "Comprehensive Income." This guidance eliminates the option to report other comprehensive income and its components in the statement of changes in equity. Companies can elect to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements. The Company is currently evaluating which method it will utilize to present items of net income and other comprehensive income. This presentation guidance is effective for the Company on October 1, 2012.

In September 2011, the FASB issued authoritative accounting guidance included in ASC Topic 350, "Intangibles—Goodwill and Other". This guidance amends the requirements for goodwill impairment testing. The Company 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, the Company determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is unnecessary. This guidance is effective for the Company for its annual goodwill impairment testing for the year ending September 30, 2013.

Revolving Credit Facility and Term Loan—In December 2010, TD Group's wholly owned subsidiary, TransDigm Inc., entered into a senior secured credit facility, which consisted of a $1.55 billion term loan facility and a $245 million revolving credit facility (collectively, the "Existing Senior Secured Credit Facility"). The proceeds of the term loan were used to pay the purchase price of and related transaction expenses associated with the acquisition of McKechnie Aerospace and repay a portion of the amounts outstanding under the previous senior secured credit facility. The remaining amount of the previous senior secured credit facility was repaid from a portion of the 7³/4% Senior Subordinated Notes due 2018 (the "2018 Notes") proceeds.

On February 14, 2011, TransDigm Inc. entered into a new senior secured credit facility which provides for a $1.55 billion term loan facility (the "New Senior Secured Credit Facility"), which was fully drawn on February 14, 2011. The New Senior Secured Credit Facility replaced the term loan under the Existing Senior Secured Credit Facility and modified certain terms of the original agreement including extending the maturity date of the term loan and modifying the interest rate provisions.

On March 25, 2011, TransDigm entered into Amendment No. 1 (the "Amendment") to the Existing Senior Secured Credit Facility. The Amendment provides for a modification to certain terms of the permitted indebtedness covenant contained in the Existing Senior Secured Credit Facility to modify the requirements for incurring certain additional senior indebtedness.

Under the terms of the New Senior Secured Credit Facility, TransDigm is entitled on one or more occasions, subject to the satisfaction of certain conditions, to request additional term loans under the New Senior Secured Credit Facility in the aggregate principal amount of up to $500 million (less any increase in the commitments under the revolving credit facility and/or additional term loans under the term loan facility under the Existing Senior Secured Credit Facility) to the extent that existing or new lenders agree to provide such additional term loans.

At September 30, 2011, the Company had $8.0 million letters of credit outstanding and $237.0 million of borrowings available under the Existing Senior Secured Credit Facility, as amended. Under the Existing Senior Secured Credit Facility, the revolving credit facility matures in December 2015.

Under the New Senior Secured Credit Facility, the term loan matures in February 2017. The term loan under the New Senior Secured Credit Facility requires quarterly principal payments of $3.9 million that began on March 31, 2011.

The interest rates per annum applicable to the term loan under the New Senior Secured Credit Facility will be, at TransDigm's option, equal to either an alternate base rate or an adjusted LIBO rate for one, two, three or six-month (or to the extent agreed to by each relevant lender, nine or twelve-month) interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted LIBO rate is subject to a floor of 1%. At September 30, 2011, the applicable interest rate on the term loan was 4.0%.

On June 27, 2011, the Company entered into three forward-starting interest rate swap agreements beginning December 31, 2012 to hedge the variable interest rates on the New Senior Secured Credit Facility for a fixed rate based on an aggregate notional amount of $353 million through June 30, 2015. These forward-starting interest rate swap agreements will effectively convert the variable interest rate on the aggregate notional amount of the New Senior Secured Credit Facility to a fixed rate of 5.17% over the term of the interest rate swap agreements.

Under the terms of the New Senior Secured Credit Facility, the Company is required to pay the administrative agent certain fees. In addition, under the Existing Senior Secured Credit Facility, on the last day of each calendar quarter the Company is required to pay a commitment fee equal to the applicable rate per annum in effect from time to time of any unused commitments under the revolving credit line and certain other fees in respect of letters of credit that may be outstanding thereunder from time to time.

All of the indebtedness outstanding under the credit facilities is guaranteed by TD Group and all of TransDigm's current and future domestic restricted subsidiaries (other than immaterial subsidiaries), and is secured by a first priority security interest in substantially all of the existing and future property and assets, including inventory, equipment, general intangibles, intellectual property, investment property and other personal property (but excluding leasehold interests and certain other assets) of TransDigm and all of TransDigm's existing and future domestic restricted subsidiaries (other than immaterial subsidiaries), and a first priority pledge of the capital stock of TransDigm and its domestic subsidiaries and 65% of the voting capital stock of certain of TransDigm's foreign subsidiaries.

The credit facilities contain certain covenants that limit the ability of TD Group, TransDigm and TransDigm's restricted subsidiaries to, among other things, incur or guarantee additional indebtedness or issue preferred stock, pay distributions on, redeem or repurchase capital stock or redeem or repurchase subordinated debt, make investments, sell assets, enter into agreements that restrict distributions or other payments from restricted subsidiaries to TransDigm, incur or suffer to exist liens securing indebtedness, consolidate, merge or transfer all or substantially all of their assets, and engage in transactions with affiliates. At September 30, 2011, TransDigm was in compliance with all of the covenants contained in the credit facilities.

The term loan under the New Senior Secured Credit Facility requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as therein defined), commencing 90 days after the end of each fiscal year, commencing with the fiscal year ending September 30, 2012, subject to certain exceptions. In addition, subject to certain exceptions (including, with respect to asset sales, the reinvestment in productive assets), TransDigm will be required to prepay the loans outstanding under the term loan facility at 100% of the principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of certain asset sales and issuance or incurrence of certain indebtedness. In addition, if, prior to February 14, 2012, the principal amount of the term loans are (i) prepaid substantially concurrently with the incurrence by TD Group, TransDigm or any of its subsidiaries of new bank loans that have an effective yield lower than the yield in effect on the term loans so prepaid or (ii) received by a lender due to a mandatory assignment following the failure of such lender to consent to an amendment of the New Senior Secured Credit Facility that has the effect of reducing the effective interest rate with respect to the term loans, such prepayment or receipt shall be accompanied by a premium of 1.0%.

Senior Subordinated Notes—In December 2010, TransDigm issued $1.6 billion in aggregate principal amount of its 2018 Notes at an issue price of 100% of the principal amount. The 2018 Notes represent unsecured obligations of TransDigm Inc. ranking subordinate to TransDigm Inc.'s senior debt, as defined in the indenture governing the 2018 Notes. Interest under the 2018 Notes is payable semi-annually.

Prior to December 15, 2013, TransDigm is permitted to redeem specified percentages of the 2018 Notes from the proceeds of equity offerings at a redemption price of 107.75%, plus accrued and unpaid interest. The 2018 Notes are redeemable by TransDigm, in whole or in part, at specified redemption prices, which decline from 103.875% to 100% over the remaining term of the 2018 Notes, plus accrued and unpaid interest. If a change in control of the Company occurs, the holders of the 2018 Notes will have the right to demand that TransDigm redeem the 2018 Notes at a purchase price equal to 101% of the principal amount of the 2018 Notes plus accrued and unpaid interest. The 2018 Notes contain many of the same restrictive covenants included in the New Senior Secured Credit Facility. TransDigm is in compliance with all of the covenants contained in the 2018 Notes.

TransDigm utilized a portion of the proceeds from the 2018 Notes to purchase its 7³/4% Senior Subordinated Notes due 2014 (the "2014 Notes").

The Company recorded refinancing costs of $72.5 million during the fiscal year ended September 30, 2011 representing charges resulting from the refinancing of TransDigm's entire debt structure. The charge for the fiscal year ended September 30, 2011 consisted of the premium of $41.9 million paid to redeem the 2014 Notes, the write-off of debt issue costs and unamortized note premium and discount of $25.7 million, and the settlement of the interest rate swap agreement and other expenses of $4.9 million.

At September 30, 2011, future maturities of long-term debt are as follows (in thousands):

Special Cash Dividend Payment—In October 2009, TransDigm made a special cash dividend to its stockholders of $7.65 per share and cash dividend equivalents payments ("Dividend Equivalent Payments") to holders of options to purchase its common stock from the net proceeds of the $425 million Senior Subordinated Notes due 2014 issued in October 2009. After the payment of debt issue fees and expenses, the net proceeds amounted to approximately $404.5 million. The special cash dividend and Dividend Equivalent Payments of $404.9 million were paid in the first quarter of fiscal 2010 and Dividend Equivalent Payments of $2.8 million were paid in the first quarter of fiscal 2011. The $425 million of 2014 Notes were included in the tender offer made in conjunction with the 2018 Notes issuance.

ENVIRONMENTAL LIABILITIES

Our operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations that govern, among other things, discharges of pollutants into the air and water, the generation, handling, storage and disposal of hazardous materials and wastes, the remediation of contamination and the health and safety of our employees. Environmental laws and regulations may require that the Company investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. At certain facilities acquired in connection with the acquisition of McKechnie Aerospace or third-party sites utilized by subsidiaries of McKechnie Aerospace, subsidiaries of the Company have been identified as potentially responsible parties under the federal Superfund laws and comparable state laws. The Company is currently involved in the investigation and remediation of a number of sites under applicable laws.

Estimates of the Company's environmental liabilities are based on current facts, laws, regulations and technology. These estimates take into consideration the Company's prior experience and professional judgment of the Company's environmental specialists. Estimates of the Company's environmental liabilities are further subject to uncertainties regarding the nature and extent of site contamination, the range of remediation alternatives available, evolving remediation standards, imprecise engineering evaluations and cost estimates, the extent of corrective actions that may be required and the number and financial condition of other potentially responsible parties, as well as the extent of their responsibility for the remediation.

Accordingly, as investigation and remediation proceed, it is likely that adjustments in the Company's accruals will be necessary to reflect new information. The amounts of any such adjustments could have a material adverse effect on the Company's results of operations or cash flows in a given period. Based on currently available information, however, the Company does not believe that future environmental costs in excess of those accrued with respect to sites for which the Company has been identified as a potentially responsible party are likely to have a material adverse effect on the Company's financial condition.

Environmental liabilities are recorded when the liability is probable and the costs are reasonably estimable, which generally is not later than at completion of a feasibility study or when the Company has recommended a remedy or has committed to an appropriate plan of action. The liabilities are reviewed periodically and, as investigation and remediation proceed, adjustments are made as necessary. Liabilities for losses from environmental remediation obligations do not consider the effects of inflation and anticipated expenditures are not discounted to their present value. The liabilities are not reduced by possible recoveries from insurance carriers or other third parties, but do reflect anticipated allocations among potentially responsible parties at federal Superfund sites or similar state-managed sites, third party indemnity obligations, and an assessment of the likelihood that such parties will fulfill their obligations at such sites.

The Company's consolidated balance sheet includes the following for environmental remediation obligations (in thousands):


	September 30, 2011
Accrued liabilities	$	1,000
Other non-current liabilities		18,888

Total	$	19,888

The entire disclosure for environmental loss contingencies, such as presence of hazardous waste, relevant information from reports issued by regulators, and estimated costs to achieve compliance with regulatory requirements. This element may be used for all of an entity's disclosures about environmental loss contingencies.

Stock-Based Compensation

Stock-Based Compensation [Abstract]

Stock-Based Compensation

16.

STOCK-BASED COMPENSATION

The Company's stock compensation plans are designed to assist the Company in attracting, retaining, motivating and rewarding key employees, directors or consultants, and promoting the creation of long-term value for stockholders by closely aligning the interests of these individuals with those of the Company's stockholders. The Company's stock compensation plans provide for the granting of stock options, restricted stock and other stock-based incentives.

The following table shows the expense recognized by the Company for stock-based compensation (in thousands):


	Fiscal Years Ended September 30,
	2011		2010		2009
Stock option compensation expense:
Performance vested stock options	$	12,568	$	6,693	$	5,695
Time vested stock options		—		—		87
Restricted stock award amortization		6		11		31

	$	12,574	$	6,704	$	5,813

The weighted-average grant date fair value of options granted during the fiscal years ended September 30, 2011, 2010 and 2009 was $33.51, $18.83 and $10.45, respectively.

Compensation expense is recognized based upon probability assessments of awards that are expected to vest in future periods. Such probability assessments are subject to revision and, therefore, unrecognized compensation expense is subject to future changes in estimate. As of September 30, 2011, there was approximately $17.0 million of total unrecognized compensation expense related to non-vested awards expected to vest, which is expected to be recognized over a weighted-average period of three years.

The fair value of the Company's employee stock options was estimated at the date of grant using a Black-Scholes-Merton option-pricing model with the following weighted average assumptions for all options granted during the fiscal years ended:


	Fiscal Years Ended September 30,
	2011	2010	2009
Risk-free interest rate	1.67% to 2.53%	2.45% to 2.96%	1.82% to 2.68%
Expected life of options	6 years	6 years	6 years
Expected dividend yield of stock	—	—	—
Expected volatility of stock	40%	40%	35%

The risk-free interest rate is based upon the Treasury bond rates as of the grant date. The average expected life of stock-based awards is based on vesting schedules and contractual terms. Expected volatility of stock was calculated using a rate based upon the historical volatility of publicly traded companies in the Company's peer group in the aerospace industry. This was used because TD Group's common stock has only been publicly traded since March 2006. Notwithstanding the special cash dividend paid in October 2009, the Company historically has not paid regular cash dividends and does not anticipate paying regular cash dividends in future periods; thus, no dividend rate assumption is used.

The total fair value of shares vested during fiscal years ended September 30, 2011, 2010, and 2009 was $7.8 million, $4.6 million and $4.9 million, respectively.

2006 Stock Incentive Plan

In conjunction with the consummation of the initial public offering, a 2006 stock incentive plan was adopted by TD Group. In July 2008 and March 2011, the plan was amended to increase the number of shares available for issuance thereunder. TD Group has reserved 8,119,668 shares of its common stock for issuance to key employees, directors or consultants under the plan. Awards under the plan may be in the form of options, restricted stock or other stock-based awards. Options granted under the plan will expire no later than the tenth anniversary of the applicable date of grant of the options, and will have an exercise price of not less than the fair market value of our common stock on the date of grant. Restricted stock granted under the plan vests over three years.

On February 24, 2011, the 2006 stock incentive plan was amended to add a market based "sweep," on all outstanding options under the 2006 stock incentive plan which provides that all options will accelerate and become fully vested if the closing price of the Company's common stock exceeds $160 per share on any 60 trading days during any consecutive 12-month period.

During the fiscal year ended September 30, 2011, 1,420 shares of common stock were issued with a weighted-average grant date fair value of $84.30.

Restricted Stock—The following table summarizes activity for restricted stock awards for the fiscal year ended September 30, 2011:


	Number of Shares			Weighted-Average Grant Date Fair Value
Outstanding at September 30, 2010		264		$	37.97
Granted		—			—
Vested		(220	)		37.97
Forfeited		(44	)		37.97

Outstanding at September 30, 2011		—		$	—

Performance Vested Stock Options—All of the options granted through September 30, 2011 under the 2006 stock incentive plan have been pursuant to an equity incentive program adopted by the Company in 2008. Under the 2008 equity incentive program, all of the options granted will vest based on the Company's achievement of established operating performance goals. The following table summarizes the activity, pricing and other information for the Company's performance vested stock-based award activity during the fiscal year ended September 30, 2011:


	Number of Options			Weighted-Average Exercise Price Per Option		Weighted-Average Remaining Contractual Term		Aggregate Intrinsic Value

At September 30, 2011, 3,400,151 remaining shares were available for award under TD Group's 2006 stock incentive plan.

2003 Stock Option Plan

Certain executives and key employees of the Company were granted stock options under TD Group's 2003 stock option plan. Upon the closing of the acquisition of the Company by Warburg Pincus in 2003, certain employees rolled over certain then-existing options to purchase shares of common stock of TransDigm Holdings. These employees were granted rollover options to purchase an aggregate of 3,870,152 shares of common stock of TD Group (after giving effect to the 149.60 for 1.00 stock split effected on March 14, 2006). All rollover options granted were fully vested on the date of grant. In addition to shares of common stock reserved for issuance upon the exercise of rollover options, an aggregate of 5,469,301 shares of TD Group's common stock were reserved for issuance upon the exercise of new management options. In general, approximately 20% of all new management options vested based on employment service or a change in control. These time vested options have a graded vesting schedule of up to four years. Approximately 80% of all new management options vested (i) based upon the satisfaction of specified performance criteria, which is annual and cumulative EBITDA As Defined targets through 2008, or (ii) upon the occurrence of a change in control if the Investor Group (defined as Warburg Pincus and the other initial investors in TD Group) received a minimum specified rate of return. Unless terminated earlier, the options expire ten years from the date of grant. All of the outstanding performance options were vested as of September 30, 2011.

TD Group has reserved a total of 9,339,453 shares of its common stock for issuance to the Company's employees under the plan, 9,261,624 of which had been issued as of September 30, 2011.

Options Not Pursuant to a Shareholder Approved Plan

In addition to the stock options issued under the 2003 stock option plan and 2006 stock incentive plan, two members of the Company's Board of Directors were also granted stock options of TD Group. Of the 134,040 options issued under these agreements, 48,096 remain outstanding with an exercise price of $6.68. All of such options were vested as of September 30, 2011.

Dividend Equivalent Plans

Pursuant to the Third Amended and Restated TransDigm Group Incorporated 2003 Stock Option Plan Dividend Equivalent Plan and the Second Amended and Restated TransDigm Group Incorporated 2006 Stock Incentive Plan Dividend Equivalent Plan, all of the options granted under the 2003 stock option plan and the 2006 stock incentive plan are entitled to certain dividend equivalent payments in the event of the declaration of a dividend by the Company. Options granted outside the plans to directors are also entitled to comparable dividend equivalents. The Company declared a special dividend of $7.65 per share in October 2009. See Note 11. As a result, holders of outstanding vested options received dividend equivalents of approximately $33.1 million in the aggregate. In addition, to the extent unvested options outstanding on the dividend declaration date vest, such options will be entitled to receive a dividend equivalent payment in the amount of $7.65 per share at the time of vesting.

FAIR VALUE MEASUREMENTS

The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. 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, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. 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 summarizes the carrying amounts and fair values of financial instruments as of September 30 (in thousands):


	Level		2011				2010
	Level		Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets:
Cash and cash equivalents		1	$	376,183	$	376,183	$	234,112	$	234,112
Liabilities:
Interest rate swaps⁽¹⁾		2		5,600		5,600		—		—
Interest rate swap⁽²⁾		2		—		—		3,865		3,865
Long-term debt:
Term loans		2		1,538,375		1,496,000		780,000		762,000

7³/4% Senior Subordinated Notes due 2014		1		—		—		991,646		1,010,000

(1)	Included in Other non-current liabilities on the Consolidated Balance Sheet.

(2)	Included in Accrued liabilities on the Consolidated Balance Sheet.

Interest rate swaps are measured at fair value using quoted market prices for the swap interest rate indexes over the term of the swap discounted to present value versus the fixed rate of the contract. The estimated fair value of the Company's term loans was based on information provided by the agent under the Company's Senior Secured Credit Facility. The estimated fair value of the Company's 7³/4% Senior Subordinated Notes was based upon quoted market prices.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Derivatives And Hedging Activities

19.

DERIVATIVES AND HEDGING ACTIVITIES

The Company is exposed to, among other things, the impact of changes in interest rates in the normal course of business. The Company's risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks, and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties.

Interest rate swap agreements are used to manage interest rate risk associated with floating-rate borrowings under our New Senior Secured Credit Facility. The interest rate swap agreements utilized by the Company effectively modify the Company's exposure to interest rate risk by converting a portion of the Company's floating-rate debt to a fixed rate basis through the expiration date of the interest rate swap agreements, thereby reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the term of the agreements without an exchange of the underlying principal amount. These derivative instruments qualify as effective cash flow hedges under GAAP. For these hedges, the effective portion of the gain or loss from the financial instruments is initially reported as a component of accumulated other comprehensive income (loss) in stockholders' equity and subsequently reclassified into earnings in the same line as the hedged item in the same period or periods during which the hedged item affects earnings.

At September 30, 2011, three forward-starting interest rate swap agreements were in place to swap variable rates on the New Senior Secured Credit Facility for a fixed rate based on an aggregate notional amount of $353 million. Beginning December 31, 2012, these interest rate swap agreements will effectively convert the variable interest rate on the aggregate notional amount of the New Senior Secured Credit Facility to a fixed rate of 5.17% (2.17% plus the 3% margin percentage) through June 30, 2015.

At September 30, 2010, an agreement was in place to swap variable interest rates on the previous senior secured credit facility for a fixed interest rate on a notional amount of $300 million through March 23, 2011. This interest rate swap agreement effectively converted the variable rate interest on the notional amount of the previous senior secured credit facility to a fixed rate of 5.04% (3.04% plus the 2% margin percentage) over the term of the agreement. The interest rate swap agreement was terminated in December 2010 in conjunction with the repayment of the outstanding term loan balance under the previous senior secured credit facility.

The entire disclosure for the entity's entire derivative instruments and hedging activities. Describes an entity's risk management strategies, derivatives in hedging activities and non-hedging derivative instruments, the assets, obligations, liabilities, revenues and expenses arising therefrom, and the amounts of and methodologies and assumptions used in determining the amounts of such items.

Summary Of Significant Accounting Policies (Policies)	12 Months Ended
Summary Of Significant Accounting Policies (Policies)	Sep. 30, 2011
Summary Of Significant Accounting Policies [Abstract]
Basis Of Presentation And Consolidation	*Basis of Presentation and Consolidation*—The accompanying consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States ("GAAP") and include the accounts of TD Group and subsidiaries. All significant intercompany balances and transactions have been eliminated.
Revenue Recognition And Related Allowances	*Revenue Recognition and Related Allowances*—Revenue is recognized from the sale of products when title and risk of loss passes to the customer, which is generally at the time of shipment. Substantially all sales are made pursuant to firm, fixed-price purchase orders received from customers. Provisions for estimated returns, uncollectible accounts and the cost of repairs under contract warranty provisions are provided for in the same period as the related revenues are recorded and are principally based on historical results modified, as appropriate, by the most current information available. Due to uncertainties in the estimation process, it is possible that actual results may vary from the estimates.
Shipping And Handling Costs	*Shipping and Handling Costs*—All shipping and handling costs are included in cost of sales in the Consolidated Statements of Income.
Research And Development Costs	*Research and Development Costs*—The Company expenses research and development costs as incurred and classifies such amounts in selling and administrative expenses. The expense recognized for research and development costs for the years ended September 30, 2011, 2010 and 2009 was approximately $19.3 million, $13.9 million, and $12.6 million, respectively.
Cash Equivalents	*Cash Equivalents* —The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Allowance For Uncollectible Accounts	*Allowance for Uncollectible Accounts*—The Company reserves for amounts determined to be uncollectible based on specific identification of losses and estimated losses based on historical experience. The allowance also incorporates a provision for the estimated impact of disputes with customers. The determination of the amount of the allowance for doubtful accounts is subject to significant levels of judgment and estimation by management. If circumstances change or economic conditions deteriorate or improve, the allowance for doubtful accounts could increase or decrease.
Inventories	*Inventories*—Inventories are stated at the lower of cost or market. Cost of inventories is determined by the average cost and the first-in, first-out (FIFO) methods for all locations except CEF Industries, Inc. which determines the cost of inventories using the last-in, first-out (LIFO) method. Approximately 5% of the inventory was valued under the LIFO method at September 30, 2011. Provision for potentially obsolete or slow-moving inventory is made based on management's analysis of inventory levels and future sales forecasts. In accordance with industry practice, all inventories are classified as current assets even though a portion of the inventories may not be sold within one year.
Property, Plant And Equipment	*Property, Plant and Equipment*—Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: land improvements from 10 to 20 years, buildings and improvements from 5 to 30 years, machinery and equipment from 2 to 10 years and furniture and fixtures from 3 to 10 years. Property, plant and equipment is assessed for potential impairment whenever indicators of impairment are present by determining whether the carrying value of the property can be recovered through projected, undiscounted cash flows from future operations over the property's remaining estimated useful life. Any impairment recognized is the amount by which the carrying amount exceeds the fair value of the asset.
Debt Issue Costs, Premiums And Discounts	*Debt Issue Costs, Premiums and Discounts*—The cost of obtaining financing as well as premiums and discounts are amortized using the effective interest method over the terms of the respective obligations/securities.
Intangible Assets	*Intangible Assets*—Intangible assets consist of identifiable intangibles acquired or recognized in accounting for the acquisitions (trademarks, trade names, technology, order backlog and a license agreement) and goodwill. Goodwill and intangible assets that have indefinite useful lives (trademarks and trade names) are subject to annual impairment testing. Management determines fair value using a discounted future cash flow analysis or other accepted valuation techniques. A two-step impairment test is used to identify potential goodwill impairment. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of a reporting unit (as defined) with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired, and the second step of the goodwill impairment test is unnecessary. The second step measures the amount of impairment, if any, by comparing the carrying value of the goodwill associated with a reporting unit to the implied fair value of the goodwill derived from the estimated overall fair value of the reporting unit and the individual fair values of the other assets and liabilities of the reporting unit. GAAP requires that the annual, and any interim, impairment assessment be performed at the reporting unit level. The reporting unit level is the operating subsidiary level for the Company. Substantially all goodwill was determined and recognized for each operating subsidiary pursuant to the accounting for the merger or acquisition as of the date of each transaction, and therefore the allocation of goodwill among reporting units was immaterial for purposes of the impairment assessment. With respect to acquisitions integrated into an existing operating subsidiary, any related goodwill is combined with goodwill of the operating subsidiary. The impairment test for indefinite lived intangible assets consists of a comparison between their fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their fair values, an impairment loss will be recognized in an amount equal to the sum of any such excesses. The Company assesses the recoverability of its amortizable intangible assets only when indicators of impairment are present by determining whether the amortization over their remaining lives can be recovered through projected, undiscounted cash flows from future operations. Amortization of amortizable intangible assets is computed using the straight-line method over the following estimated useful lives: technology from 20 to 22 years, order backlog over one year, and a license agreement over 20 years. Prior to fiscal 2010, the annual impairment test of goodwill and indefinite-lived intangible assets was performed as of the last day of our fourth quarter. During fiscal 2010, the measurement date was changed to the first day of the fourth fiscal quarter. As a result of our growth and increase in the number of reporting units, we believe the change in our measurement date is preferable in order to provide additional time to quantify the fair value of our reporting units and to evaluate the results of the impairment testing.
Stock Option Plans	*Stock Option Plans*—The Company records stock-based compensation measured using the fair value method of accounting. Compensation expense is recorded over the vesting periods of the options.
Income Taxes	*Income Taxes*—The Company accounts for income taxes using an asset and liability approach. Deferred taxes are recorded for the difference between the book and tax basis of various assets and liabilities. A valuation allowance is provided when it is more likely than not that some or all of a deferred tax asset will not be realized.
Contingencies	*Contingencies*—During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows. The Company believes that its potential exposure to such legal actions is adequately covered by its aviation product and general liability insurance.
Estimates	*Estimates*—The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Comprehensive Income (Loss)	*Comprehensive Income (Loss)*—The term "comprehensive income (loss)" represents the change in stockholders' equity from transactions and other events and circumstances resulting from non-stockholder sources. The Company's accumulated other comprehensive income or loss, consisting principally of fair value adjustments to its interest rate swaps (net of tax), cumulative foreign currency translation adjustments and pension liability adjustments (net of tax), is reported separately in the accompanying consolidated statements of changes in stockholders' equity. See Note 20 to the Consolidated Financial Statements.
Segment Reporting	*Segment Reporting*—Management evaluates the Company as one reporting segment in the aerospace industry. The Company is engaged in the design, manufacture and sale of highly engineered aircraft components used in aerospace and defense applications through its wholly-owned subsidiaries. Substantially all of the Company's operations are located within the United States.
Earnings Per Share	*Earnings per Share*—Earnings per share information is determined using the two-class method, which includes the weighted-average number of common shares outstanding during the period and other securities that participate in dividends ("participating securities"). Our vested stock options are considered "participating securities" because they include non-forfeitable rights to dividends. In applying the two-class method, earnings are allocated to both common stock shares and participating securities based on their respective weighted-average shares outstanding for the period. Diluted earnings per share information may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated using the treasury stock method.
