	Elektro-Metall Export GmbH – On March 6, 2014, TransDigm Germany GmbH, a newly formed subsidiary of TransDigm Inc., acquired Elektro-Metall Export GmbH (“EME”) for approximately $49.5 million, which comprises $40.3 million in cash plus the assumption of approximately $9.2 million of net indebtedness. EME manufactures proprietary, highly engineered aerospace electromechanical actuators, electrical and electromechanical components and assemblies for commercial aircraft, helicopters and other specialty applications. These products fit well with TransDigm’s overall business direction. EME is included in TransDigm’s Power & Control segment. The Company expects that the approximately $23.7 million of goodwill recognized for the acquisition will not be deductible for tax purposes.
	Airborne Global Inc. – On December 19, 2013, TransDigm Inc. acquired all of the outstanding stock of Airborne Global Inc. (“Airborne”) for approximately $263.8 million in cash, which comprises the $250 million contract price plus estimated cash and working capital at closing and which is subject to adjustments based on the actual level of cash and working capital as of the closing date of the acquisition. Airborne is the industry leading designer and manufacturer of personnel parachutes, cargo aerial delivery systems, emergency escape systems, naval decoys and other related products. These products fit well with TransDigm’s overall business direction. Airborne is included in TransDigm’s Airframe segment. The Company expects that the approximately $156.2 million of goodwill recognized for the acquisition will not be deductible for tax purposes.
	Whippany Actuation Systems, LLC – On June 28, 2013, Whippany Actuation Systems, LLC, a newly formed subsidiary of TransDigm Inc., acquired assets from GE Aviation’s Electromechanical Actuation Division (“Whippany Actuation”) for approximately $151.5 million in cash, which includes a purchase price adjustment of $2.7 million paid in the first quarter of fiscal 2014. Whippany Actuation manufactures proprietary, highly engineered aerospace electromechanical motion control subsystems for civil and military applications with product offerings including control electronics, motors, high power mechanical transmissions and actuators. These products fit well with TransDigm’s overall business direction. Whippany is included in TransDigm’s Power & Control segment. The Company expects that the approximately $105.1 million of goodwill recognized for the acquisition will be deductible for tax purposes.
	Arkwin Industries, Inc. – On June 5, 2013, TransDigm Inc. acquired all of the outstanding stock of Arkwin Industries, Inc. (“Arkwin”), for approximately $285.7 million in cash, which includes a purchase price adjustment of $0.2 million received in the fourth quarter of fiscal 2013. Arkwin manufactures proprietary, highly engineered aerospace hydraulic and fuel system components for commercial and military aircraft, helicopters and other specialty applications. These products fit well with TransDigm’s overall business direction. Arkwin is included in TransDigm’s Power & Control segment. The Company expects that the approximately $184.9 million of goodwill recognized for the acquisition will not be deductible for tax purposes.
	Aerosonic Corporation – On June 5, 2013, Buccaneer Acquisition Sub Inc., a newly formed subsidiary of TransDigm Inc., completed the tender offer of a majority of the outstanding stock of Aerosonic Corporation (“Aerosonic”). Buccaneer Acquisition Sub Inc. was subsequently merged into Aerosonic on June 10, 2013; in connection therewith, all outstanding shares of Aerosonic were cancelled and Aerosonic became a wholly owned subsidiary of TransDigm Inc. The aggregate price paid in the tender offer and merger was approximately $39.8 million in cash. Aerosonic designs and manufactures proprietary, highly engineered mechanical and digital altimeters, airspeed indicators, rate of climb indicators, microprocessor controlled air data test sets, angle of attack stall warning systems, integrated air data sensors and other aircraft sensors, monitoring systems and flight instrumentation for use on commercial and military aircraft. These products fit well with TransDigm’s overall business direction. Aerosonic is included in TransDigm’s Airframe segment. The Company expects that the approximately $14.8 million of goodwill recognized for the acquisition will not be deductible for tax purposes.
	The Company accounted for 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 EME and Airborne; 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 had they occurred at the beginning of the applicable thirty-nine week periods ended June 28, 2014 or June 29, 2013 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.

	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 which creates a new topic in the Accounting Standards Codification (“ASC”) Topic 606, “Revenue From Contracts With Customers.” In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishes a new control-based revenue recognition model; changes the basis for deciding when revenue is recognized over time or at a point in time; provides new and more detailed guidance on specific topics; and expands and improves disclosures about revenue. In addition, ASU 2014-09 adds a new Subtopic to the Codification, ASC 340-40, “Other Assets and Deferred Costs: Contracts with Customers,” to provide guidance on costs related to obtaining a contract with a customer and costs incurred in fulfilling a contract with a customer that are not in the scope of another ASC Topic. The guidance is effective for the Company for annual reporting periods, including interim periods therein, for the year ending September 30, 2018. Early application is not permitted. Companies are permitted to apply the guidance in ASC 606 using one of the following two methods: retrospectively to each prior period presented in accordance with ASC 250, subject to certain practical expedients; or retrospectively with a cumulative effect adjustment to opening retained earnings in the period of initial adoption. If applying this transition method, an entity should apply the new revenue recognition guidance only to contracts not completed under existing U.S. GAAP at the date of adoption. The Company is currently evaluating the adoption method to apply and the impact that the update will have on its financial position, results of operations, cash flows and financial statement disclosures.

	Trade Receivable Securitization Facility – During the quarter ended December 28, 2013, the Company established a trade receivable securitization facility (the “Securitization Facility”). The Securitization Facility effectively increases the Company’s borrowing capacity by up to $225 million depending on the amount of trade accounts receivable, and matures on October 20, 2014. The Securitization Facility includes the right for the Company to exercise annual one year extensions as long as there have been no termination events as defined by the agreement. As of June 28, 2014, the Company has borrowed $200 million under the Securitization Facility. The Securitization Facility is collateralized by substantially all of the company’s trade accounts receivable.
	Tender Offer – Senior Subordinated Notes due 2018 – On May 9, 2014, the Company announced a cash tender offer (the “Tender Offer”) for any and all of its outstanding 7.75% Senior Subordinated Notes due 2018 (the “2018 Notes”). On June 4, 2014, the Company purchased approximately $1.209 billion aggregate principal amount of the 2018 Notes for total consideration of $1,076.69 (plus accrued and unpaid interest) for each $1,000 aggregate principal amount, which includes a consent payment of $30.00 per $1,000 principal amount, for the 2018 Notes validly tendered and not validly withdrawn in the Tender Offer as of May 22, 2014. In addition, the Company issued a notice of redemption with respect to any and all of its 2018 Notes that remained outstanding following the expiration of the Tender Offer. On June 27, 2014, the Company, pursuant to the terms of the indenture governing the 2018 Notes, satisfied and discharged the $390.7 million of 2018 Notes that remained outstanding by depositing with the trustee sufficient funds to repurchase all such 2018 Notes at a redemption price of $1,070.17 (plus accrued and unpaid interest) for each $1,000 aggregate principal amount of 2018 Notes.
	The Company recorded refinancing costs of $131.5 million during the thirty-nine week period ended June 28, 2014 representing debt issue costs expensed in conjunction with the redemption of the 2018 Notes. The charge consisted of the premium of $121.0 million paid to redeem the 2018 Notes and the write-off of debt issue costs of $10.5 million.
	Second Amended and Restated Credit Facility – On June 4, 2014, TransDigm Inc. amended and restated its existing credit agreement dated February 28, 2013, by entering into a Second Amended and Restated Credit Agreement (the “2014 Credit Facility”). The 2014 Credit Facility permits, among other things, (i) the payment of a special dividend of up to $1.7 billion to the holders of TD Group’s common stock, par value $.01 per share, (ii) the issuance of the 2022 Notes and the 2024 Notes (each as defined below), (iii) the incurrence of certain new tranche D term loans (the “Tranche D Term Loans”) in an aggregate principal amount equal to $825 million, which Tranche D Term Loans were fully drawn on June 4, 2014 and mature on June 4, 2021, (iv) the increase of the total revolving commitments thereunder to $420 million, which includes a sublimit of up to $100 million of multicurrency revolving commitments, and (v) certain changes to certain affirmative and negative covenants and the financial covenant thereunder. The terms and conditions that apply to the Tranche D Term Loans, including pricing, are substantially the same as the terms and conditions that apply to the other term loans under the 2014 Credit Facility. In addition, the Revolving A Credit Commitments previously available under the credit facility were terminated.
	The term loan facilities under the 2014 Credit Facility (the “Term Loan Facility”) now consist of three tranches of term loans—Tranche B Term Loans, Tranche C Term Loans and Tranche D Term Loans. The Revolving Credit Facility now consists of one tranche—Revolving B Commitments, which include up to $100 million of multicurrency revolving commitments. The Tranche B Term Loans consist of $500 million in the aggregate maturing on February 14, 2017, the Tranche C Term Loans consist of $2,600 million in the aggregate maturing on February 28, 2020 and the Tranche D Term Loans consist of $825 million in the aggregate maturing on June 4, 2021. The Term Loan Facility requires quarterly principal payments of $7.8 million, which began on March 28, 2013, and an additional quarterly principal payment of $2.1 million beginning September 30, 2014. The Revolving B Commitments consist of $420 million in the aggregate and mature on February 28, 2018. At June 28, 2014, the Company had $6.9 million letters of credit outstanding and $413.1 million of borrowings available under the 2014 Credit Facility.
	Under the terms of the 2014 Credit Facility, TransDigm is entitled on one or more occasions, subject to the satisfaction of certain conditions, to request additional commitments under the Revolving Credit Facility or additional term loans in the aggregate principal amount of up to $1.0 billion to the extent that existing or new lenders agree to provide such additional term loans.
	All of the indebtedness outstanding under the 2014 Credit Facility is guaranteed by TD Group and all of TransDigm’s current and future domestic restricted subsidiaries (other than immaterial subsidiaries). In addition, the obligations of TransDigm and the guarantors under the 2014 Credit Facility are secured ratably in accordance with each lender’s respective revolving and term loan commitments 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 its existing and future domestic restricted subsidiaries (other than immaterial subsidiaries), and a first priority pledge of the capital stock of TransDigm and its subsidiaries (other than foreign subsidiaries and certain domestic subsidiaries, of which 65% of the voting capital stock is pledged).
	The interest rates per annum applicable to the loans under the 2014 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 .75%. At June 28, 2014 the applicable interest rate was 3.50% on the Tranche B Term Loan and 3.75% on the Tranche C and Tranche D Term Loans.
	The Term Loan Facility requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as defined in the 2014 Credit Facility), commencing 90 days after the end of each fiscal year, commencing with the fiscal year ending September 30, 2014, 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 December 4, 2014 with respect to Tranche B and Tranche C Term Loans and June 4, 2015 with respect to Tranche D Term Loans, the principal amount of the term loans are (i) prepaid substantially concurrently with the incurrence by TD Group, TransDigm or any 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 2014 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%.
	The 2014 Credit Facility contains certain covenants that limit the ability of TD Group, TransDigm and TransDigm’s restricted subsidiaries to, among other things: (i) incur or guarantee additional indebtedness or issue preferred stock; (ii) pay distributions on, redeem or repurchase capital stock or redeem or repurchase subordinated debt; (iii) make investments; (iv) sell assets; (v) enter into agreements that restrict distributions or other payments from restricted subsidiaries to TransDigm; (vi) incur or suffer to exist liens securing indebtedness; (vii) consolidate, merge or transfer all or substantially all of their assets; and (viii) engage in transactions with affiliates.
	Issuance of New Senior Subordinated Notes – On June 4, 2014, TransDigm Inc. issued $2.350 billion in aggregate principal amount of senior subordinated notes, consisting of $1.150 billion aggregate principal amount of 6.00% Senior Subordinated Notes due 2022 (the “2022 Notes”) and $1.200 billion aggregate principal amount of 6.50% Senior Subordinated Notes due 2024 (the “2024 Notes,” and, together with the 2022 Notes, the “New Notes”) at an issue price of 100% of the principal amount for each series of the New Notes.
	The 2022 Notes bear interest at the rate of 6.0% per annum, which accrues from June 4, 2014 and is payable semiannually in arrears on January 15 and July 15 of each year, commencing on January 15, 2015. The 2022 Notes mature on July 15, 2022, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indenture governing the 2022 Notes (the “2022 Indenture”).
	The 2024 Notes bear interest at the rate of 6.5% per annum, which accrues from June 4, 2014 and is payable semiannually in arrears on January 15 and July 15 of each year, commencing on January 15, 2015. The 2024 Notes mature on July 15, 2024, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indenture governing the 2024 Notes (the “2024 Indenture”).
	The New Notes are subordinated to all of TransDigm’s existing and future senior debt, rank equally with all of its existing and future senior subordinated debt and rank senior to all of its future debt that is expressly subordinated to the New Notes. The New Notes are guaranteed on a senior subordinated unsecured basis by TD Group and its wholly-owned domestic subsidiaries named in the 2022 and 2024 Indentures. The guarantees of the New Notes are subordinated to all of the guarantors’ existing and future senior debt, rank equally with all of their existing and future senior subordinated debt and rank senior to all of their future debt that is expressly subordinated to the guarantees of the New Notes. The New Notes are structurally subordinated to all of the liabilities of TD Group’s non-guarantor subsidiaries.
	Each of the 2022 and 2024 Indentures contain certain covenants that, among other things, limit the incurrence of additional indebtedness, the payment of dividends, transactions with affiliates, asset sales, acquisitions, mergers, and consolidations, liens and encumbrances, and prepayments of certain other indebtedness. The 2022 and 2024 Indentures contain events of default customary for agreements of their type (with customary grace periods, as applicable) and provide that, upon the occurrence of an event of default arising from certain events of bankruptcy or insolvency, all outstanding New Notes of each series will become due and payable immediately without further action or notice. If any other type of event of default occurs and is continuing, then the trustee or the holders of at least 25% in principal amount of the then outstanding New Notes of a particular series may declare all such notes to be due and payable immediately.
	The proceeds of Tranche D Term Loans, the Securitization Facility and the issuance of the New Notes were used to purchase the 2018 Notes and to pay a special cash dividend and cash dividend equivalent payments under the Company’s dividend equivalent plans related to its outstanding stock options.
	Special Cash Dividend – On June 4, 2014 the Company’s board of directors authorized and declared a special cash dividend of $25.00 on each outstanding share of common stock and cash dividend equivalent payments under its stock option plans. The special cash dividend amounting to approximately $1,324.8 million was paid on June 26, 2014 and dividend equivalent payments amounting to approximately $106.1 million were paid on June 27, 2014. In addition, during the thirteen week period ended June 28, 2014 the Company made $4.8 million of dividend equivalent payments related to previous year’s cash dividend payments for unvested options granted prior to October 1, 2012 that become fully vested under the market sweep provisions thereof.

	At the end of each reporting period, TD Group makes an estimate of its annual effective income tax rate. The estimate used in the year-to-date period may change in subsequent periods. During the thirteen week periods ended June 28, 2014 and June 29, 2013, the effective income tax rate was 22.5% and 32.9%, respectively. The lower effective tax rate for the thirteen week period ended June 28, 2014 was primarily due to a discrete item related to adjustments resulting from the filing of the Company’s September 30, 2013 federal income tax return. During the thirty-nine week periods ended June 28, 2014 and June 29, 2013, the effective income tax rate was 32.8% and 32.5%, respectively. The Company’s effective tax rate for these periods was less than the Federal statutory tax rate due primarily to the domestic manufacturing deduction.
	The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions as well as foreign jurisdictions located in Belgium, China, France, Germany, Hungary, Malaysia, Mexico, Singapore, Sri Lanka and the United Kingdom. The Company is subject to U.S. federal examinations for its 2011 and 2012 tax years. AmSafe is subject to U.S. federal examinations for the 2008, 2009, 2010 and 2011 years. In addition, the Company is subject to state income tax examinations for fiscal years 2009 and later.
	At June 28, 2014 and September 30, 2013, TD Group had $6.1 million and $6.1 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $5.7 million and $5.7 million on the effective tax rate at June 28, 2014 and September 30, 2013, respectively. The Company does not believe that the tax positions that comprise the unrecognized tax benefit amount will change significantly over the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

	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.

DERIVATIVES AND HEDGING ACTIVITIES	'
	11	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 the Company’s 2014 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 cash flow hedges, the effective portion of the gain or loss from the financial instruments was 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 affected earnings.
	On July 16, 2013, the Company entered into three forward-starting interest rate swap agreements beginning September 30, 2014 to hedge the variable interest rates on the 2014 Credit Facility for a fixed rate based on an aggregate notional amount of $1.0 billion through June 30, 2019. These forward-starting interest rate swap agreements will effectively convert the variable interest rate on the aggregate notional amount of the 2014 Credit Facility to a fixed rate of 5.4% (2.4% plus the 3% margin percentage) over the term of the interest rate swap agreements.
	At June 28, 2014, three forward-starting interest rate swap agreements were in place to swap variable rates on the 2014 Credit Facility for a fixed rate based on an aggregate notional amount of $353 million. These interest rate swap agreements converted the variable interest rate on the aggregate notional amount of the 2014 Credit Facility to a fixed rate of 5.17% (2.17% plus the 3% margin percentage) through June 30, 2015.
	In conjunction with the refinancing of the 2011 Credit Facility, the Company no longer designated the interest rate swap agreements relating to the $353 million aggregate notional amount as cash flow hedges for accounting purposes. Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss in stockholder’s equity will be amortized into earnings over the remaining period of the swap agreements. The net after-tax loss included in accumulated other comprehensive loss to be reclassified into interest expense over the remaining term of the swap agreement was $2.6 million at June 28, 2014.

SEGMENTS	'
	12	SEGMENTS
	The Company’s businesses are organized and managed in three reporting segments: Power & Control, Airframe and Non-aviation.
	The Power & Control segment includes operations that primarily develop, produce and market systems and components that predominately provide power to or control power of the aircraft utilizing electronic, fluid, power and mechanical motion control technologies. Major product offerings include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices and specialized AC/DC electric motors and generators. Primary customers of this segment are engine and power system and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.
	The Airframe segment includes operations that primarily develop, produce and market systems and components that are used in non-power airframe applications utilizing airframe and cabin structure technologies. Major product offerings include engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, cockpit security components and systems, aircraft audio systems, specialized lavatory components, seatbelts and safety restraints, engineered interior surfaces, lighting and control technology, personnel parachutes, cargo aerial delivery systems, emergency escape systems and naval decoys. Primary customers of this segment are airframe manufacturers and cabin system suppliers and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.
	The Non-aviation segment includes operations that primarily develop, produce and market products for non-aviation markets. Major product offerings include seatbelts and safety restraints for ground transportation applications, mechanical/electro-mechanical actuators and controls for space applications, and refueling systems for heavy equipment used in mining, construction and other industries. Primary customers of this segment are off road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers and manufacturers of heavy equipment used in mining, construction and other industries.
	The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items including refinancing costs, acquisition-related costs, transaction-related costs and non-cash compensation charges incurred in connection with the Company’s stock option plans. Acquisition-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction related costs comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments.
	EBITDA As Defined is not a measurement of financial performance under GAAP. Although the Company uses EBITDA As Defined to assess the performance of its business and for various other purposes, the use of this non-GAAP financial measure as an analytical tool has limitations, and it should not be considered in isolation or as a substitute for analysis of the Company’s results of operations as reported in accordance with GAAP.
	The Company’s segments are reported on the same basis used internally for evaluating performance and for allocating resources. The accounting policies for each segment are the same as those described in the summary of significant accounting policies in the Company’s consolidated financial statements. Intersegment sales and transfers are recorded at values based on market prices, which creates intercompany profit on intersegment sales or transfers that is eliminated in consolidation. Intersegment sales were insignificant for the periods presented below.
