NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

TWENTY-SIX WEEK PERIODS ENDED MARCH 29, 2014 AND MARCH 30, 2013

(UNAUDITED)

1. DESCRIPTION OF THE BUSINESS

2. UNAUDITED INTERIM FINANCIAL INFORMATION

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s financial position and results of operations and cash flows for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the year ended September 30, 2013 included in TD Group’s Form 10-K dated November 15, 2013. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“GAAP”). The September 30, 2013 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the twenty-six week period ended March 29, 2014 are not necessarily indicative of the results to be expected for the full year.

3. ACQUISITIONS

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 $21.4 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 $157.1 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 $103.9 million of goodwill recognized for the acquisition will be deductible for tax purposes.

-6-

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 $185.1 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 $14.7 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, Airborne, Whippany Actuation, Arkwin and Aerosonic; 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 twenty-six week periods ended March 29, 2014 or March 30, 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.

7. INCOME TAXES

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 March 29, 2014 and March 30, 2013, the effective income tax rate was 33.7% and 31.9%, 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 lower effective tax rate for the thirteen week period ended March 30, 2013 was primarily due to the non-recurring retroactive reinstatement of the research and development tax credit. During the twenty-six week periods ended March 29, 2014 and March 30, 2013, the effective income tax rate was 33.6% and 32.2%, 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 decrease in the effective tax rate for the twenty-six week period ended March 30, 2013 was primarily due to the retroactive reinstatement of the research and development tax credit.

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 no longer subject to U.S. federal examinations for years before fiscal 2011. 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 March 29, 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 March 29, 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.

8. 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 (in thousands):

			March 29, 2014				September 30, 2013
	Level		Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets:
Cash and cash equivalents		1	$	475,691	$	475,691	$	564,740	$	564,740
Liabilities:
Interest rate swap agreements (1)		2		6,200		6,200		6,950		6,950

7 3/4% Senior Subordinated Notes due 2018		1		1,600,000		1,708,000		1,600,000		1,708,000
5 1/2% Senior Subordinated Notes due 2020		1		550,000		558,000		550,000		540,000
7 1/2% Senior Subordinated Notes due 2021		1		500,000		550,000		500,000		536,000

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

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

Interest rate swaps were 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 values of the Company’s 2018 Notes, 2020 Notes and 2021 Notes were based upon quoted market prices.

9. 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

-9-

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 2013 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 that 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 2013 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 2013 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 March 29, 2014, three forward-starting interest rate swap agreements were in place to swap variable rates on the 2013 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 2013 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 $3.3 million at March 29, 2014.

10. 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.

-10-

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.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of the Company’s financial condition and results of operations should be read together with TD Group’s consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q. References in this section to “TransDigm,” “the Company,” “we,” “us,” “our,” and similar references refer to TD Group, TransDigm Inc. and TransDigm Inc.’s subsidiaries, unless the context otherwise indicates. The following discussion may contain predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties, including those discussed in this report. These risks could cause our actual results to differ materially from any future performance suggested below.

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including, in particular, the statements about the Company’s plans, strategies and prospects under this section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Although the Company believes that its plans, intentions and expectations reflected in or suggested by such forward-looking statements are reasonable, the Company can give no assurance that such plans, intentions or expectations will be achieved. Many of the factors affecting these forward-looking statements are outside the control of the Company. Consequently, such forward-looking statements should be regarded solely as the Company’s current plans, estimates and beliefs. The Company does not undertake, and specifically declines, any obligation to publicly release the results of any revisions to these forward-looking statements that may be made to reflect any future events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events, except as required by applicable law. All forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by the foregoing cautionary statements.

Important factors that could cause actual results to differ materially from the forward-looking statements made in this Quarterly Report on Form 10-Q include but are not limited to: the sensitivity of our business to the number of flight hours that our customers’ planes spend aloft and our customers’ profitability, both of which are affected by general economic conditions; future terrorist attacks; our reliance on certain customers; the U.S. defense budget and risks associated with being a government supplier; failure to maintain government or industry approvals; failure to complete or successfully integrate acquisitions; our substantial indebtedness; potential environmental liabilities; and other factors. Please refer to the other information included in this Quarterly Report on Form 10-Q and to the Annual Report on Form 10-K for additional information regarding the foregoing factors that may affect our business.

Overview

We believe we are a leading global designer, producer and supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft in service today. Our business is well diversified due to the broad range of products we offer to our customers. Some of our more significant 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, seatbelts and safety restraints, engineered interior surfaces, lighting and control technology and military personnel parachutes and cargo delivery systems. Each of these product offerings is composed of many individual products that are typically customized to meet the needs of a particular aircraft platform or customer.

For the second quarter of fiscal 2014, we generated net sales of $590.8 million and net income of $90.4 million. EBITDA As Defined was $263.0 million, or 44.5% of net sales. See below for certain information regarding EBITDA and EBITDA As Defined, including reconciliations of EBITDA and EBITDA As Defined to net income and net cash provided by operating activities.

Certain Acquisitions

Elektro-Metall Export GmbH Acquisition

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 is in the process of obtaining information to value certain tangible and intangible assets of EME, and therefore the consolidated financial statements at March 29, 2014 reflect a preliminary purchase price allocation for the business.

Airborne Global Inc. Acquisition

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 is in the process of obtaining information to value certain tangible and intangible assets of Airborne, and therefore the consolidated financial statements at March 29, 2014 reflect a preliminary purchase price allocation for the business.

Aerosonic Corporation Acquisition

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 is in the process of obtaining information to value certain tangible and intangible assets of Aerosonic, and therefore the consolidated financial statements at March 29, 2014 reflect a preliminary purchase price allocation for the business.

Non-GAAP Financial Measures

We present below certain financial information based on our EBITDA and EBITDA As Defined. References to “EBITDA” mean earnings before interest, taxes, depreciation and amortization, and references to “EBITDA As Defined” mean EBITDA plus, as applicable for each relevant period, certain adjustments as set forth in the reconciliations of net income to EBITDA and EBITDA As Defined and the reconciliations of net cash provided by operating activities to EBITDA and EBITDA As Defined presented below.

-20-

Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under accounting principles generally accepted in the United States of America (“GAAP”). We present EBITDA and EBITDA As Defined because we believe they are useful indicators for evaluating operating performance and liquidity.

Our management believes that EBITDA and EBITDA As Defined are useful as indicators of liquidity because securities analysts, investors, rating agencies and others use EBITDA to evaluate a company’s ability to incur and service debt. In addition, EBITDA As Defined is useful to investors because the revolving credit facility under our senior secured credit facility requires compliance under certain circumstances, on a pro forma basis, with a financial covenant that measures the ratio of the amount of our secured indebtedness to the amount of our Consolidated EBITDA defined in the same manner as we define EBITDA As Defined herein.

In addition to the above, our management uses EBITDA As Defined to review and assess the performance of the management team in connection with employee incentive programs and to prepare its annual budget and financial projections. Moreover, our management uses EBITDA As Defined to evaluate acquisitions.

Although we use EBITDA and EBITDA As Defined as measures to assess the performance of our business and for the other purposes set forth above, the use of these non-GAAP financial measures as analytical tools has limitations, and you should not consider any of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with GAAP. Some of these limitations are:

• neither EBITDA nor EBITDA As Defined reflects the significant interest expense, or the cash requirements necessary to service interest payments, on our indebtedness;

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and neither EBITDA nor EBITDA As Defined reflects any cash requirements for such replacements;

• the omission of the substantial amortization expense associated with our intangible assets further limits the usefulness of EBITDA and EBITDA As Defined;

• neither EBITDA nor EBITDA As Defined includes the payment of taxes, which is a necessary element of our operations; and

• EBITDA As Defined excludes the cash expense we have incurred to integrate acquired businesses into our operations, which is a necessary element of certain of our acquisitions.

Because of these limitations, EBITDA and EBITDA As Defined should not be considered as measures of discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by not viewing EBITDA or EBITDA As Defined in isolation and specifically by using other GAAP measures, such as net income, net sales and operating profit, to measure our operating performance. Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with GAAP. Our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

Critical Accounting Policies

Our consolidated financial statements have been prepared in accordance with GAAP, which often requires the judgment of management in the selection and application of certain accounting principles and methods. Management believes that the quality and reasonableness of our most critical policies enable the fair presentation of our financial position and results of operations. However, investors are cautioned that the sensitivity of financial statements to these methods, assumptions and estimates could create materially different results under different conditions or using different assumptions.

A summary of our significant accounting policies and estimates is included in the Annual Report on Form 10-K for the year ended September 30, 2013. There have been no significant changes to our critical accounting policies during the twenty-six week period ended March 29, 2014.

Gross profit percentage		52.1	%		55.7	%

The increase in the dollar amount of cost of sales during the thirteen week period ended March 29, 2014 was primarily due to increased volume associated with the sales from acquisitions and organic sales growth as well as higher acquisition-related costs as shown in the table above.

Gross profit as a percentage of sales decreased by 3.6 percentage points to 52.1% for the thirteen week period ended March 29, 2014 from 55.7% for the thirteen week period ended March 30, 2013. The dollar amount of gross profit increased by $48.3 million, or 18.6%, for the quarter ended March 29, 2014 compared to the comparable quarter last year due to the following items:

• Gross profit on the sales from the acquisitions indicated above (excluding acquisition-related costs) was approximately $36 million for the quarter ended March 29, 2014, which represented gross profit of approximately 37% of the acquisition sales.

• Organic sales growth described above, application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers), and positive leverage on our fixed overhead costs spread over a higher production volume, resulted in a net increase in gross profit of approximately $19 million for the quarter ended March 29, 2014.

• The gross profit increase described above was partially offset by higher inventory purchase accounting adjustments and acquisition integration costs charged to cost of sales of approximately $7 million for the quarter ended March 29, 2014.

• Selling and Administrative Expenses. Selling and administrative expenses increased by $16.0 million to $71.5 million, or 12.1% of sales, for the thirteen week period ended March 29, 2014 from $55.5 million, or 11.9% of sales, for the thirteen week period ended March 30, 2013. Selling and administrative expenses and the related percentage of total sales for the thirteen week periods ended March 29, 2014 and March 30, 2013 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	March 29, 2014			March 30, 2013			Change		% Change
Selling and administrative expenses - excluding costs below	$	61.8		$	48.7		$	13.1		26.9	%
% of total sales		10.5	%		10.5	%
Stock compensation expense		6.9			6.1			0.8		13.1	%

Total selling and administrative expenses	$	71.5		$	55.5		$	16.0		28.8	%
% of total sales		12.1	%		11.9	%

The increase in the dollar amount of selling and administrative expenses during the quarter ended March 29, 2014 is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $11 million, which was approximately 11% of the acquisition sales, and increased acquisition related expenses of approximately $2.1 million.

• Amortization of Intangible Assets. Amortization of intangible assets increased to $17.6 million for the quarter ended March 29, 2014 from $9.7 million for the comparable quarter last year. The net increase of $7.9 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months partially offset by order backlog from prior acquisitions becoming fully amortized.

• Refinancing Costs. Refinancing costs of $30.3 million were recorded during the quarter ended March 30, 2013 representing debt issue costs expensed in conjunction with the refinancing of our 2010 Credit Facility and 2011 Credit Facility in February 2013.

• Interest Expense-net. Interest expense-net includes interest on outstanding borrowings, amortization of debt issue costs and revolving credit facility fees offset by interest income. Interest expense-net increased $18.2 million, or 28.4%, to $82.3 million for the quarter ended March 29, 2014 from $64.1 million for the comparable quarter last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $5.72 billion for the quarter ended March 29, 2014 and approximately $4.33 billion for the quarter ended March 30, 2013. The increase in borrowings was primarily due to additional borrowings of $36.4 million relating to our refinancing of the 2011 Credit Facility in February 2013, additional borrowings of $900 million relating to the Incremental Term Facility in July 2013 and the issuance in July 2013 of our $500 million 2021 Notes. The weighted average interest rate for cash interest payments on total outstanding borrowings was 5.4% at March 29, 2014 and 5.5% at March 30, 2013.

• Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 33.7% for the quarter ended March 29, 2014 compared to 31.9% for the quarter ended March 30, 2013. 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 lower effective tax rate for the quarter ended March 30, 2013 was primarily due to non-recurring adjustments related to the retroactive reinstatement of the research and development tax credit.

• Net Income. Net income increased $22.5 million, or 33.1%, to $90.4 million for the quarter ended March 29, 2014 compared to net income of $67.9 million for the quarter ended March 30, 2013, primarily as a result of the factors referred to above.

• Earnings per Share. The basic and diluted earnings per share were $1.49 for the quarter ended March 29, 2014 and $1.25 per share for the quarter ended March 30, 2013. Net income for the thirteen week period ended March 29, 2014 of $90.4 million was decreased by an allocation of dividends on participating securities of $5.5 million, or $0.10 per share, resulting in net income available to common shareholders of $84.9 million. The increase in earnings per share of $0.24 per share to $1.49 per share is a result of the factors referred to above.

Gross profit percentage		52.8	%		55.6	%

The increase in the dollar amount of cost of sales during the twenty-six week period ended March 29, 2014 was primarily due to increased volume associated with the sales from acquisitions and organic sales growth as well as higher acquisition-related costs as shown in the table above.

Gross profit as a percentage of sales decreased by 2.8 percentage points to 52.8% for the twenty-six week period ended March 29, 2014 from 55.6% for the twenty-six week period ended March 30, 2013. The dollar amount of gross profit increased by $93.8 million, or 18.9%, for the twenty-six week period ended March 29, 2014 compared to the comparable twenty-six week period last year due to the following items:

• Gross profit on the sales from the acquisitions indicated above (excluding acquisition-related costs) was approximately $59 million for the twenty-six week period ended March 29, 2014, which represented gross profit of approximately 38% of the acquisition sales.

• Organic sales growth described above, application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers), and positive leverage on our fixed overhead costs spread over a higher production volume, resulted in a net increase in gross profit of approximately $43 million for the twenty-six week period ended March 29, 2014.

The increase in the dollar amount of selling and administrative expenses during the twenty-six week period ended March 29, 2014 is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $16 million, which was approximately 10% of the acquisition sales, and higher acquisition related expenses of $2.1 million partially offset by lower stock compensation expense of approximately $1.6 million.

• Amortization of Intangible Assets. Amortization of intangible assets increased to $34.0 million for the twenty-six week period ended March 29, 2014 from $20.3 million for the comparable twenty-six week period last year.

Backlog

As of March 29, 2014, the Company estimated its sales order backlog at $1,253 million compared to an estimated sales order backlog of $895 million as of March 30, 2013. The increase in backlog is primarily due to acquisitions, totaling approximately $314 million. The majority of the purchase orders outstanding as of March 29, 2014 are scheduled for delivery within the next twelve months. Purchase orders may be subject to cancellation or deferral by the customer prior to shipment. The level of unfilled purchase orders at any given date during the year will be materially affected by the timing of the Company’s receipt of purchase orders and the speed with which those orders are filled. Accordingly, the Company’s backlog as of March 29, 2014 may not necessarily represent the actual amount of shipments or sales for any future period.

Foreign Operations

Although we manufacture a significant portion of our products in the United States, we manufacture some products in Belgium, China, Germany, Hungary, Malaysia, Mexico, Sri Lanka and the United Kingdom. We sell our products in the United States as well as in foreign countries. Although the majority of sales of our products are made to customers including distributors located in the United States, our products are ultimately sold to and used by customers, including airlines and other end users of aircraft, throughout the world. A number of risks inherent in international operations could have a material adverse effect on our results of operations, including currency fluctuations, difficulties in staffing and managing multi-national operations, general economic and political uncertainties and potential for social unrest in countries in which we operate, limitations on our ability to enforce legal rights and remedies, restrictions on the repatriation of funds, change in trade policies, tariff regulation, difficulties in obtaining export and import licenses and the risk of government financed competition.

There can be no assurance that foreign governments will not adopt regulations or take other action that would have a direct or indirect adverse impact on the business or market opportunities of the Company within such governments’ countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to our operations and growth strategy.

TransDigm has $3,100 million in fully drawn term loans (the “Term Loan Facility”) and a $310 million Revolving Credit Facility (together with the Term Loan Facility, the “2013 Credit Facility”).

The Term Loan Facility consists of two tranches of term loans—tranche B term loans and tranche C term loans, and the Revolving Credit Facility consists of two tranches—revolving A commitments and revolving B commitments. The tranche B term loans consist of $500 million in the aggregate and the tranche C term loans consist of $1,700 million in the aggregate. The tranche B term loans mature on February 14, 2017 and the tranche C term loans mature on February 28, 2020. The Term Loan Facility requires quarterly principal payments of $5.5 million which began on March 28, 2013.

The revolving A commitments consist of $32 million in the aggregate and the revolving B commitments consist of $278 million in the aggregate. The revolving A commitments mature on December 6, 2015 and the revolving B commitments mature on February 28, 2018. At March 29, 2014, the Company had $7.3 million letters of credit outstanding and $302.7 million of borrowings available under the 2013 Credit Facility.

-31-

The interest rates per annum applicable to the loans under the 2013 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 March 29, 2014, applicable interest rate on the tranche B term loan was 3.50% and the tranche C term loan was 3.75%.

At December 28, 2013, three forward-starting interest rate swap agreements were in place to swap variable rates on the 2013 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 2013 Credit Facility to a fixed rate of 5.17% (2.17% plus the 3% margin percentage) through June 30, 2015.

The Term Loan Facility requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as defined in the 2013 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 February 28, 2014, 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 2013 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%.

Indentures

In December 2010, TransDigm Inc. issued $1.6 billion in aggregate principal amount of its 7 ³/₄% Senior Subordinated Notes due 2018 (the “2018 Notes”) at an issue price of 100% of the principal amount. Such notes do not require principal payments prior to their maturity in December 2018. Interest under the 2018 Notes is payable semi-annually.

In October 2012, TransDigm Inc. issued $550 million in aggregate principal amount of its 5 ¹/₂% Senior Subordinated Notes due 2020 (“2020 Notes”) at an issue price of 100% of the principal amount. Such notes do not require principal payments prior to their maturity in October 2020. Interest under the 2020 Notes is payable semi-annually.

In July 2013, the Company issued $500 million in aggregate principal amount of its 7 ¹/₂% Senior Subordinated Notes due 2021 (“2021 Notes” and together with the 2018 Notes and the 2020 Notes, the “Notes”) at an issue price of 100% of the principal amount. Such notes do not require principal payments prior to their maturity in July 2021. Interest under the 2021 Notes is payable semi-annually. The Notes represent unsecured obligations of TransDigm Inc. ranking subordinate to TransDigm Inc.’s senior debt, as defined in the applicable Indentures.

Certain Restrictive Covenants in Our Debt Documents

The credit facility and the Indentures contain restrictive 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 other indebtedness. In addition if the total amount of revolving loans and letters of credit exceeds 25% of the aggregate revolving commitment, the credit facility requires that the Company meet a net debt to EBITDA As Defined ratio, on a pro forma basis. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the credit facilities or the Indentures. If any such default occurs, the lenders under the credit facilities and the holders of the Notes may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under the credit facilities also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the credit facilities, the lenders thereunder will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash, and they will also have the right to prevent us from making debt service payments on the Notes.

Trade Receivables Securitization

During the quarter ended December 28, 2013, the Company established a trade receivables 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 Company expects to utilize proceeds from the securitization program as an alternative to other forms of debt, effectively reducing borrowing costs. As of March 29, 2014, the Company had not borrowed any amounts under the Securitization Facility.

-32-

Stock Repurchase Program

On August 22, 2011, the Board of Directors authorized a common share repurchase program, which was announced on August 23, 2011. Under the terms of the program, the Company may purchase up to a maximum aggregate value of $100 million of its shares of common stock. On October 29, 2013, we announced a new program replacing that program permitting us to repurchase a portion of our outstanding shares not to exceed $200 million in the aggregate. No repurchases were made under the program during the quarter ended March 29, 2014.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Our main exposure to market risk relates to interest rates. Our financial instruments that are subject to interest rate risk principally include fixed-rate and floating-rate long-term debt. At March 29, 2014, we had borrowings under our 2013 Credit Facility of $3.07 billion that were subject to interest rate risk. Borrowings under our 2013 Credit Facility bear interest, at our option, at a rate equal to either an alternate base rate or an adjusted LIBO rate for a one-, two-, three- or six-month (or to the extent available to each lender, nine- or twelve-month) interest period chosen by us, in each case, plus an applicable margin percentage. Accordingly, the Company’s cash flows and earnings will be exposed to the market risk of interest rate changes resulting from variable rate borrowings under our 2013 Credit Facility. The effect of a hypothetical one percentage point increase in interest rates would increase the annual interest costs under our 2013 Credit Facility by approximately $30.7 million based on the amount of outstanding borrowings at March 29, 2014. The weighted average interest rate on the $3.07 billion of borrowings under our 2013 Credit Facility on March 29, 2014 was 3.8%.

At March 29, 2014, three forward-starting interest rate swap agreements were in place to swap variable rates on the 2013 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 2013 Credit Facility to a fixed rate of 5.17% (2.17% plus the 3% margin percentage) through June 30, 2015.

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 2013 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 2013 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.

The fair value of the $3.07 billion aggregate principal amount of borrowings under our 2013 Credit Facility is exposed to the market risk of interest rates. The estimated fair value of such term loan approximated $3.08 billion at March 29, 2014 based upon information provided to the Company from its agent under the 2013 Credit Facility. The fair value of the $1.60 billion aggregate principal amount of our 2018 Notes, $0.55 billion 2020 Notes and our $0.50 billion 2021 Notes due are exposed to the market risk of interest rate changes. The estimated fair value of the 2018 Notes approximated $1.7 billion, the estimated fair value of the 2020 Notes approximated $0.56 billion and the estimated fair value of the 2021 Notes approximated $0.55 billion at March  29, 2014 based upon quoted market rates.

ITEM 4. CONTROLS AND PROCEDURES

As of March 29, 2014, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial and Accounting Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that TD Group’s disclosure controls and procedures are effective to ensure that information required to be disclosed by TD Group in the reports it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to TD Group’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, TD Group’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures. There have been no significant changes in TD Group’s internal controls or other factors that could significantly affect the internal controls subsequent to the date of TD Group’s evaluations.

-33-

Changes in Internal Control over Financial Reporting

On March 6, 2014 we acquired EME. EME operated under its own set of systems and internal controls and we are currently maintaining those systems and much of that control environment until we are able to incorporate EME’s processes into our own systems and control environment. We currently expect to complete the incorporation of EME’s operations into our systems and control environment in fiscal 2015.

There have been no other changes to our internal controls over financial reporting that could have a material effect on our financial reporting during the quarter ended March 29, 2014.

PART II: OTHER INFORMATION

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the risk factors disclosed in Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2013. There have been no material changes to the risk factors set forth therein.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS: PURCHASES OF EQUITY SECURITIES BY THE ISSUER

On August 22, 2011, the Board of Directors authorized a common share repurchase program, which was announced on August 23, 2011. Under the terms of the program, the Company may purchase up to a maximum aggregate value of $100 million of its shares of common stock. On October 29, 2013, a new program replacing that program permitting the Company to repurchase a portion of its outstanding shares not to exceed $200 million in the aggregate was announced. During the quarter ended March 29, 2014, the Company did not repurchase any shares under the program.

Segments

10. 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.

Fair Value Measurements

8. 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 (in thousands):

			March 29, 2014				September 30, 2013
	Level		Carrying Amount		Fair Value		Carrying Amount		Fair Value

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

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

Interest rate swaps were 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 values of the Company’s 2018 Notes, 2020 Notes and 2021 Notes were based upon quoted market prices.

Income Taxes

7. INCOME TAXES

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 March 29, 2014 and March 30, 2013, the effective income tax rate was 33.7% and 31.9%, 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 lower effective tax rate for the thirteen week period ended March 30, 2013 was primarily due to the non-recurring retroactive reinstatement of the research and development tax credit. During the twenty-six week periods ended March 29, 2014 and March 30, 2013, the effective income tax rate was 33.6% and 32.2%, 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 decrease in the effective tax rate for the twenty-six week period ended March 30, 2013 was primarily due to the retroactive reinstatement of the research and development tax credit.

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 no longer subject to U.S. federal examinations for years before fiscal 2011. 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 March 29, 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 March 29, 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.

Derivatives and Hedging Activities

9. 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 2013 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 that 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 2013 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 2013 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 March 29, 2014, three forward-starting interest rate swap agreements were in place to swap variable rates on the 2013 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 2013 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 $3.3 million at March 29, 2014.

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 $14.7 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, Airborne, Whippany Actuation, Arkwin and Aerosonic; 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 twenty-six week periods ended March 29, 2014 or March 30, 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.
