NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

TWENTY-SIX WEEK PERIODS ENDED MARCH 30, 2019 AND MARCH 31, 2018

(UNAUDITED)

1. DESCRIPTION OF THE BUSINESS

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

TransDigm's major product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, NiCad batteries and chargers, engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, databus and power controls, cockpit security components and systems, specialized cockpit displays, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems.

On March 14, 2019, TransDigm completed its acquisition of Esterline Technologies Corporation ("Esterline"). Refer to Note 3, "Acquisitions and Divestitures," for further information on this acquisition. Esterline includes a collection of approximately 20 reporting units that primarily develop, produce and market products for the aerospace and defense industry. TransDigm is currently in the process of integrating Esterline as well as evaluating the strategic fit and description of each individual Esterline reporting unit.

2. UNAUDITED INTERIM FINANCIAL INFORMATION

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting 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, 2018 included in TD Group’s Form 10-K filed on November 9, 2018. 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, 2018 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 30, 2019 are not necessarily indicative of the results to be expected for the full year.

3. ACQUISITIONS AND DIVESTITURES

During the twenty-six week period ended March 30, 2019, the Company completed the acquisitions of Esterline and substantially all of the assets and technical data rights of NavCom Defense Electronics ("NavCom"). During the fiscal year ended September 30, 2018, the Company completed the acquisitions of Skandia Inc. ("Skandia"), Extant, and the Kirkhill elastomers business ("Kirkhill"). The Company accounted for the acquisitions using the acquisition method and included the results of operations of the acquisitions in its condensed consolidated financial statements from the effective date of each acquisition. As of March 30, 2019, the one-year measurement period is open for Esterline, NavCom, Skandia and Extant; therefore, the assets acquired and liabilities assumed related to these acquisitions are subject to adjustment until the end of their respective one-year measurement periods. The Company is in the process of obtaining a third-party valuation of certain intangible assets and tangible assets of Esterline and Skandia.

Pro forma net sales and results of operations for the Esterline acquisition are provided in the Esterline section below. The pro forma information presents consolidated financial information as if Esterline had been acquired at the beginning of fiscal year 2018 on October 1, 2017. Pro forma net sales and results of operations for the acquisitions, other than Esterline, had they occurred at the beginning of the applicable twenty-six week period ended March 30, 2019 or March 31, 2018 are not material 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).

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 25 to 30 years.

Esterline – On March 14, 2019, TransDigm completed the acquisition of all the outstanding stock of Esterline for $122.50 per share in cash, plus the payoff of Esterline debt. The purchase price, net of cash acquired of approximately $398.2 million, totaled approximately $3,923.9 million. Of the $3,923.9 million purchase price, $3,536.3 million was paid at closing and the remaining $387.6 million was classified as restricted cash at March 30, 2019 for the redemption of the outstanding senior notes due 2023 (herein the "2023 Notes"). The 2023 Notes were redeemed on April 15, 2019. Refer to Note 9, "Debt," for additional information. Esterline, through its subsidiaries, is an industry leader in specialized manufacturing for the aerospace and defense industry, including significant aftermarket exposure, primarily within three core disciplines - advanced materials, avionics and controls and sensors and systems. The acquisition of Esterline expands TransDigm's platform of proprietary and sole source content for the aerospace and defense industry. Esterline has been identified as a separate segment at March 30, 2019. Refer to Note 13, "Segments," for additional information about Esterline's products and the Company's segments.

The total purchase price of Esterline was allocated to the underlying assets acquired and liabilities assumed based upon management’s estimated fair values at the date of acquisition. To the extent the purchase price exceeded the estimated fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill. The preliminary allocation of the fair value of the Esterline acquisition is summarized in the table below (presented in thousands). Allocations are based on the acquisition method of accounting and in-process third-party valuation appraisals. Given the timing and complexity of the Esterline acquisition, the allocation of the purchase price is preliminary and will likely change in future periods, perhaps materially, as fair value estimates of the assets acquired and liabilities assumed are refined and finalized during the allowable one year measurement period.

Except where otherwise noted in the Notes to Condensed Consolidated Financial Statements, changes in balances and activity where comparable periods are presented in the condensed consolidated financial statements were generally driven by the Esterline acquisition.



Assets acquired:
Current assets, excluding cash acquired	$	1,482,442
Property, plant, and equipment	338,990
Other intangible assets	992,000
Goodwill	2,431,180
Other	49,710
Total assets acquired	5,294,322
Liabilities assumed:
Current liabilities	843,653
Other noncurrent liabilities	526,819
Total liabilities assumed	1,370,472
Net assets acquired	$	3,923,850

The Company currently expects that the approximately $2.4 billion of goodwill and $1.0 billion of other intangible assets recognized for the acquisition will not be deductible for tax purposes.

The Company's net sales and income from continuing operations for the thirteen and twenty-six week periods ended March 30, 2019 include net sales of $122.0 million and income from continuing operations before tax of $7.5 million related to the Esterline acquisition. Net income from continuing operations for the thirteen and twenty-six week periods ended March 30, 2019 includes approximately $3.5 million of other intangible asset amortization expense and $14.9 million of inventory step-up amortization expense in cost of sales, respectively.

Acquisition costs were expensed as incurred. In fiscal 2019, approximately $22.0 million of acquisition-related costs have been incurred. These costs were recorded in selling and administrative expenses within the condensed consolidated statements of income. In connection with the financing of the Esterline acquisition, approximately $24.5 million of net interest expense (comprised of gross interest expense of $32.7 million and interest income of $8.2 million) has been recorded in fiscal 2019.

Table of Contents

The following pro forma information presents consolidated financial information as if Esterline had been acquired at the beginning of fiscal year 2018 on October 1, 2017. Interest expense has been adjusted as though the debt incurred to finance the Esterline acquisition had been outstanding at October 1, 2017. Each quarter presented includes other intangible asset amortization expense of approximately $21.2 million resulting from the preliminary purchase accounting. The full $118.7 million of inventory step-up amortization resulting from the preliminary purchase accounting asset step-up has been included in the fiscal year 2018 pro forma results to reflect the pro forma transaction date of October 1, 2017, and thus the inventory step-up amortization expense of $14.9 million recorded in the thirteen and twenty-six week periods ended March 30, 2019 has been excluded.

The unaudited pro forma consolidated financial information does not necessarily reflect the actual results that would have occurred had the acquisition taken place on October 1, 2017, nor is it meant to be indicative of future results of operations of the combined companies under the ownership and operation of the Company.

NavCom develops, manufactures, and supports high-reliability, mission-critical electronics, avionics and sub-assemblies. NavCom is included as a product line of Extant, which is included in TransDigm's Power and Control segment. The Company expects that approximately $9 million of goodwill recognized for the acquisition will be deductible for tax purposes over 15 years.

Skandia – On July 13, 2018, the Company acquired all of the outstanding stock of Skandia for a total purchase price of approximately $84.3 million, which includes a $0.2 million working capital settlement paid in the fourth quarter of fiscal 2018. Skandia provides highly engineered seating foam, foam fabrication, flammability testing and acoustic solutions for the business jet market. Skandia is included as a product line within an existing reporting unit in TransDigm's Airframe segment. The Company expects that no goodwill recognized for the acquisition will be deductible for tax purposes.

Extant – On April 24, 2018, the Company acquired all of the outstanding stock of Extant for a total purchase price of approximately $534.6 million in cash, which is net of a $0.2 million working capital settlement received in the third quarter of fiscal 2018. Extant provides a broad range of proprietary aftermarket products and repair and overhaul services to the aerospace and defense end markets. Extant is included in TransDigm's Power and Control segment.

Prior to the Company's acquisition of Extant, Extant was owned by an equity fund sponsored by Warburg Pincus LLC. Michael Graff, a director of TransDigm, is a managing director of Warburg Pincus LLC and was chairman of the board of Extant. Robert Henderson, Vice Chairman of TransDigm, was also on the board of Extant and owned less than 2% of Extant on a fully diluted basis. In addition, Mr. Graff, Mr. W. Nicholas Howley, TransDigm's Executive Chairman, and Messrs. Douglas Peacock and David Barr, directors of TransDigm, each had minority interests of less than 1% in the Warburg Pincus LLC fund that owned Extant.

The total purchase price of Extant was allocated to the underlying assets acquired and liabilities assumed based upon management’s estimated fair values at the date of acquisition. To the extent the purchase price exceeded the estimated fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill. The following table summarizes the purchase price allocation of the estimated fair values of the assets acquired and liabilities assumed at the transaction date (presented in thousands).



Assets acquired:
Current assets, excluding cash acquired	$	53,698
Property, plant, and equipment	4,103
Other intangible assets	105,000
Goodwill	406,673
Total assets acquired	569,474
Liabilities assumed:
Current liabilities	9,876
Other noncurrent liabilities	25,028
Total liabilities assumed	34,904

Approximately $44 million of the $105 million other intangible assets recognized for the acquisition is deductible for tax purposes over 15 years. Of the $407 million of goodwill recognized for the acquisition, none is deductible for tax purposes.

Kirkhill – On March 15, 2018, the Company acquired the assets and certain liabilities of the Kirkhill elastomers business from Esterline for a total purchase price of approximately $49.3 million, which is net of a $0.6 million working capital settlement received in the third quarter of fiscal 2018. Kirkhill's products are primarily proprietary, sole source with significant aftermarket content and used in a broad variety of most major commercial transport and military platforms. Kirkhill is included in TransDigm's Airframe segment. No goodwill recognized for the acquisition is deductible for tax purposes.

Schroth – On February 22, 2017, the Company acquired all of the outstanding stock of Schroth Safety Products GmbH and certain aviation and defense assets and liabilities from subsidiaries of Takata Corporation (collectively, "Schroth"), for a total purchase price of approximately $89.7 million, which consisted primarily of $79.7 million paid in cash during fiscal 2017 and an approximately $9.0 million indemnity holdback, of which $8.5 million was paid in April 2018 and $0.5 million remains a reserve as of March 30, 2019.

In connection with the settlement of a Department of Justice investigation into the competitive effects of the acquisition, during the fourth quarter of fiscal 2017, the Company committed to dispose of the Schroth business. Therefore, Schroth was classified as held-for-sale beginning in the fourth quarter of fiscal 2017 and the results of operations of were reflected as discontinued operations in the consolidated financial statements.

On January 26, 2018, the Company completed the sale of Schroth in a management buyout to a private equity fund and certain members of Schroth management for approximately $61.4 million, which included a working capital adjustment of $0.3 million that was paid in July 2018.

There was no activity from discontinued operations in the thirteen and twenty-six week period ended March 30, 2019. Loss from discontinued operations was $5.6 million and $2.8 million in the condensed consolidated statements of income for the thirteen and twenty-six week periods ended March 31, 2018, respectively, which is summarized as follows (amounts in thousands):

4. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, which created a new topic in the Accounting Standards Codification (“ASC”) 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 requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also specifies the accounting of some costs to obtain or fulfill a contract with a customer and expands the disclosure requirements around contracts with customers. The Company adopted this standard in the first quarter of 2019 using the modified retrospective method. The adoption of this standard did not have a material impact on our consolidated results of operations, financial position or cash flows. Refer to Note 5, "Revenue Recognition," for additional disclosures relating to ASC 606.

In February 2016, the FASB issued ASU 2016-02, “Leases (ASC 842),” which will require that a lessee recognize assets and liabilities on the balance sheet for all leases with a lease term of more than twelve months, with the result being the recognition of a right of use asset and a lease liability. Additionally, in July 2018, the FASB issued ASU 2018-10, "Codification Improvements to ASC 842, Leases" which provides narrow amendments to clarify how to apply certain aspects of the new leases standard. The new leases standard guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2019, with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures. We are planning to adopt ASC 842 on October 1, 2019 using the modified retrospective optional transition method, in which case prior periods presented will not be restated. Also, we intend to elect the package of practical expedients, which among other things, permits us to not reassess the identification, classification and initial direct costs of leases commencing before the October 1, 2019 effective date.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments (ASU 2016-13)," which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company is currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures.

In October 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” (ASU 2016-16). This accounting standard requires companies to recognize the income tax effects of intercompany sales and transfers of assets, other than inventory, in the period in which the transfer occurs. Under previous guidance companies were required to defer the income tax effects of intercompany transfers of assets by recording prepaid taxes, until such assets were sold to an outside party or otherwise recognized. Current guidance requires companies to write off any income tax amounts previously deferred as prepaid taxes from past intercompany transactions, and to record deferred tax balances for amounts not previously recognized, through a cumulative-effect adjustment to retained earnings. ASU 2016-16 is effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those years. The Company adopted this standard in the first quarter of fiscal 2019. The adoption of this standard did not have a material impact on our consolidated financial statements. Refer to the condensed consolidated statements of stockholders' deficit for the impact of the adoption of ASU 2016-16 on retained earnings.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate Step 2 from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The adoption of this standard is not expected to have a material impact on our consolidated financial statements and disclosures.

In March 2017, the FASB issued ASU 2017-07, "Compensation—Retirement Benefits (ASC 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," that changes how employers that sponsor defined benefit and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. Under previous guidance, companies included all components of the net periodic benefit costs in the same lines as the service cost component. Current guidance requires employers to present the other components of the net periodic benefit costs separately from the line items that include the service cost and outside of any subtotal of operating income. In addition, only the service cost component will be eligible for capitalization in assets. Employers will have to disclose the lines used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. The standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within the fiscal year. The Company adopted this standard in the first quarter of fiscal 2019. The adoption of this standard did not have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, "Compensation—Stock Compensation (ASC 718): Scope of Modification Accounting," which provides clarity on which changes to the terms or conditions of share-based payment awards require

Table of Contents

an entity to apply the modification accounting provisions required in ASC 718. The standard is effective for all entities for annual periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. The Company adopted this standard in the first quarter of fiscal 2019. The adoption of this standard did not have a material impact on our consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (ASC 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which gives entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (the "Act") into retained earnings. The guidance allows entities to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the Act's new federal corporate income tax rate. The guidance also allows entities to elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the change in the federal tax rate (e.g., state taxes, changing from a worldwide tax system to a territorial system). Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. The standard is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within the fiscal year. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Entities have the option to apply the guidance retrospectively or in the period of adoption. The adoption of this standard is not expected to have a material impact on our consolidated financial statements.

In March 2018, the FASB issued ASU 2018-05, “Income Taxes (ASC 740), Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118.” The ASU adds various SEC paragraphs pursuant to the issuance of the December 2017 SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which was effective immediately. The SEC issued SAB 118 to address concerns about reporting entities’ ability to timely comply with the accounting requirements to recognize all of the effects of the Tax Cuts and Jobs Act in the period of enactment. SAB 118 allowed disclosure that timely determination of some or all of the income tax effects from the Tax Cuts and Jobs Act were incomplete by the due date of the financial statements and if possible to provide a reasonable estimate. We have finalized our accounting for the tax effects of the Tax Cuts and Jobs Act under the guidance of SAB 118. Such finalization did not result in a material impact to the provisional tax effects previously recorded in our consolidated financial statements.

In accordance with SEC Final Rule Release No. 33-10532, we have adopted Rule 3-04 of Regulation S-X during the first quarter of fiscal 2019 and have disclosed changes in the Condensed Consolidated Statements of Stockholders' Deficit for all periods presented.

In August 2018, the FASB issued ASU 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (ASC 715-20)." ASU 2018-14 modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The ASU also requires an entity to disclose the weighted-average interest crediting rates for cash balance plans and to explain the reasons for significant gains and losses related to changes in the benefit obligation. The ASU is effective January 1, 2020 and early adoption is permitted. The Company is currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures.

5. REVENUE RECOGNITION

The Company adopted ASC 606, “Revenue from Contracts with Customers,” beginning October 1, 2018 using the modified retrospective method.

The new standard primarily impacted the Company's timing of revenue recognition for certain contracts and subcontracts with the U.S. government that contain termination for convenience clauses and resulted in an increase to retained earnings of $3.3 million. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Table of Contents

The cumulative effect of the changes made to our condensed consolidated balance sheet as of October 1, 2018 for the adoption of ASC 606 were as follows (in thousands):



	September 30, 2018			Adjustments due to ASC 606			October 1, 2018
Assets
Unbilled receivables⁽¹⁾	$	10,056		$	8,272		$	18,328

Deferred income taxes	$	399,496		$	1,011		$	400,507
Accumulated deficit	(2,246,578		)	3,284			(2,243,294		)


⁽¹⁾	Included in prepaid expenses and other on the condensed consolidated balance sheet.

The impact of the adoption of ASC 606 on the condensed consolidated statements of income and condensed consolidated balance sheet was immaterial for the thirteen and twenty-six week periods ended March 30, 2019.

Accounting Policy —Revenue is recognized from the sale of products when control transfers to the customer, which is demonstrated by our right to payment, a transfer of title, a transfer of the risk and rewards of ownership, or the customer acceptance, but most frequently upon shipment where the customer obtains physical possession of the goods.

The majority of the Company's revenue is recorded at a point in time.

In some contracts the Company found that under ASC 606, control transferred to the customer over time primarily in contracts where the customer is required to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit relative to the work performed for products that were customized for the customer. Upon adoption of ASC 606, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use. Prior to the adoption date, revenue related to these agreements was recognized when the goods were shipped; as a result of the adoption of ASC 606, a portion of our revenue may be earned in periods earlier than it would have been in prior years. The cumulative adjustment to retained earnings upon adoption, which is presented in the table above, represents those earnings that would have been recognized in the previous year had ASC 606 been in effect during that time.

Based on our production cycle, it is generally expected that goods related to the revenue represented in that adjustment will be shipped and billed within the current year. For revenue recognized over time, we estimate the amount of revenue attributable to a contract earned at a given point during the production cycle based on certain costs, such as materials and labor incurred to date, plus the expected profit, which is a cost-to-cost input method.

The Company’s payment terms vary by the type and location of the customer and the products or services offered. The Company does not offer any payment terms that would meet the requirements for consideration as a significant financing component under ASC 606.

Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in the consolidated statements of income, and are not considered a performance obligation to our customers.

The Company pays sales commissions that relate to contracts for products or services that are satisfied at a point in time or over a period of one year or less and so are recorded per the practical expedient expensed as incurred. These costs are reported as a component of selling and administrative expenses in the unaudited condensed consolidated statement of operations.

We offer assurance type warranties on our products as well as separately sold warranty contracts. Revenue related to warranty contracts that are sold separately is recognized over the life of the warranty term.

Variable consideration is estimated at the expected value (sum of the probability of weighted amounts) or most likely amount, whichever method is found to be most appropriate to estimate the consideration to which the Company will be entitled, and only to the extent it is probable that a subsequent change in estimate will not result in a significant revenue reversal when estimating the amount of revenue to recognize. Variable consideration is treated as a change to the sales transaction price and based largely on an assessment of all information (i.e., historical, current and forecasted) that is reasonably available to the Company. Variable consideration is estimated at contract inception and updated at the end of each reporting period as additional information becomes available.

Contract Assets and Liabilities - Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing or reimbursable costs related to a specific contract. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts.

⁽⁴⁾	Included in other non-current liabilities on the condensed consolidated balance sheet.

Changes in the contract asset and liability balances during the twenty-six week period ended March 30, 2019 were not materially impacted by any factors other than the Esterline acquisition. For the thirteen and twenty-six week periods ended March 30, 2019, the revenue recognized that was previously included in the beginning balance of contract liabilities was immaterial.

Issuance of Senior Secured Notes due 2026 – On January 30, 2019, the Company entered into a purchase agreement in connection with a private offering of $3.8 billion aggregate principal amount of 6.25% senior secured notes due 2026. In addition, on February 1, 2019, the Company entered into a purchase agreement in connection with a private offering of $200 million aggregate principal amount of 6.25% senior secured notes due 2026 (herein the "2026 Secured Notes"). All $4.0 billion aggregate principal amount of the 2026 Secured Notes constituted a single class and were issued under a single indenture. The notes in the $3.8 billion secured notes offering were issued at a price of 100% of their principal amount and the notes in the $200 million secured notes offering were issued at a price of 101% of their principal amount. The 2026 Secured Notes are guaranteed, with certain exceptions, by TransDigm Group, TransDigm UK and all of TransDigm Inc.’s existing U.S. subsidiaries on a senior secured basis.

The 2026 Secured Notes bear interest at a rate of 6.25% per annum, which accrues from February 13, 2019 and is payable semiannually in arrears on March 15th and September 15th of each year, commencing on September 15, 2019. The 2026 Secured Notes mature on March 15, 2026, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the Secured Notes Indenture.

In addition to the premium of $2.0 million capitalized upon the issuance of the $200 million issuance of the 2026 Senior Notes, the Company capitalized $63.9 million and expensed $0.7 million of debt issuance costs associated with the issuance of the 2026 Senior Secured Notes during the twenty-six week period ended March 30, 2019.

Issuance of Senior Subordinated Notes due 2027 – On February 1, 2019, the Company entered into a purchase agreement in connection with a private offering of $550 million in new 7.50% senior subordinated notes due 2027 (herein the "2027 Notes"). The 2027 Notes were issued pursuant to an indenture, dated as of February 13, 2019, among TransDigm, as issuer, TD Group, TD UK and the other subsidiaries of TransDigm named therein, as guarantors, and The Bank of New York Mellon Trust Company, N.A., as trustee.

The 2027 Notes mature on March 15, 2027, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indenture.

The Company capitalized $5.4 million of debt issuance costs associated with the 2027 Notes during the twenty-six week period ended March 30, 2019.

Repurchase of Senior Subordinated Notes due 2020 - On February 13, 2019, the Company announced a cash tender offer for any and all of its 2020 Notes outstanding. On March 15, 2019, the Company redeemed the principal amount of $550 million, plus accrued interest of approximately $12.6 million.

The Company wrote off $1.7 million in unamortized debt issuance costs during the twenty-six week period ended March 30, 2019 in conjunction with the redemption of the 2020 Notes.

Amendment No. 6 to the Second Amended and Restated Credit Agreement - On March 14, 2019, the Company entered into Amendment No. 6 to the Second Amended and Restated Credit Agreement (herein "Amendment No. 6").

Under the terms of Amendment No. 6, certain existing lenders increased the revolving commitments, including $52.1 million in multicurrency revolving commitments, in an aggregate principal amount of $160 million, to a total revolving commitments capacity of $760 million. The revolving commitments consist of two tranches which include up to $151.5 million of multicurrency revolving commitments. The terms and conditions that apply to the revolving credit facility, other than the additional revolving credit commitments, are substantially the same as the terms and conditions that applied to the revolving credit facility immediately prior to Amendment No. 6.

At March 30, 2019, the Company had $33.7 million in letters of credit outstanding, and $726.3 million of borrowings available under the revolving commitments, subject to restrictions under existing debt covenants.

Government Refundable Advances - Government refundable advances consist of payments received from the Canadian government to assist in research and development related to commercial aviation. The requirement to repay this advance is solely based on year-over-year commercial aviation revenue growth at CMC, which is a subsidiary of TransDigm (acquired via the Esterline acquisition). This obligation was assumed in connection with the Esterline acquisition and the balance was $38.7 million at March 30, 2019.

Obligations under Capital Leases - The Company leases certain buildings and equipment under capital leases. This obligation was assumed in connection with the Esterline acquisition and the present value of the minimum capital lease payments, net of the current portion, represents a balance of $65.5 million at March 30, 2019.

Repurchase of Senior Notes due 2023 - On March 14, 2019, in connection with the closing of the Esterline acquisition, the Company announced a cash tender offer for any and all of the outstanding senior notes due 2023 (herein the "2023 Notes"). The 2023 Notes were issued by Esterline in April 2015 and remained outstanding as of the acquisition date of Esterline by TransDigm. A notice of redemption with respect to the notes was given to each holder of the 2023 Notes,

providing for the redemption of all outstanding notes on April 15, 2019 at the redemption price set forth in the related indenture.

At March 30, 2019, the funds for the redemption of the 2023 Notes of approximately $387.6 million were held in trust and were committed to be used to redeem any and all of the 2023 Notes. The funds were restricted to the redemption of the 2023 Notes, and as such, are presented as restricted cash in the condensed consolidated balance sheet at March 30, 2019. On April 15, 2019, the Company redeemed the principal amount of approximately $373.8 million (€330.0 million as the 2023 Notes were denominated in Euros), plus accrued interest of approximately $6.8 million, early redemption premium of $6.8 million and fees of approximately $0.2 million.

10. 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 30, 2019 and March 31, 2018, the effective income tax rate was 24.2% and 18.3%, respectively. During the twenty-six week periods ended March 30, 2019 and March 31, 2018, the effective income tax rate was 22.9% and (17.3)%, respectively. The Company's higher effective tax rate for the thirteen week period ended March 30, 2019 was primarily due to a net interest expense limitation under IRC Section 163(j) resulting from the provisions of The Tax Cuts and Jobs Act enacted on December 22, 2017 (the "Act"). The Company's higher effective tax rate for the twenty-six week period ended March 30, 2019 was primarily due to the discrete benefit recognized in the twenty-six week period ended March 31, 2018 related to the remeasurement of deferred tax balances resulting from certain provisions of the Act. The Company’s effective tax rate for the thirteen and twenty-six week periods ended March 30, 2019 was higher than the Federal statutory rate of 21% primarily resulting from a net interest expense limitation under IRC Section 163(j) offset by the benefit associated with the deduction for foreign-derived intangible income (FDII) and excess tax benefits for share-based payments. The Company’s effective tax rate for the thirteen and twenty-six week periods ended March 31, 2018 was less than the Federal statutory tax rate primarily due to the discrete adjustment related to the enactment of the Act described above. FDII was introduced, and interest deductibility under IRC Section 163(j) was modified by the Act and were both effective for TD Group beginning October 1, 2018.

The Act subjects a U.S. corporation to a tax on its Global Intangible Low-Taxed Income (GILTI). The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that a Company can make an accounting policy election to either treat such inclusion as a current period expense or to factor such amounts into the measurement of deferred taxes. The Company has elected to recognize the resulting tax on GILTI as a period expense in the period the tax is incurred and has not reflected any corresponding deferred taxes associated with GILTI in the condensed consolidated financial statements.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. The Company is currently under audit in Belgium for fiscal years 2016 through 2018, in France for fiscal years 2015 through 2017, and in Germany for fiscal years 2012 through 2015. The Company is no longer subject to U.S. federal examinations for years before fiscal year 2014. The fiscal year 2014 U.S. federal income tax return is currently under review by the Appeals Office of the Internal Revenue Service. In addition, the Company is subject to state income tax examinations for fiscal years 2011 and later.

At March 30, 2019 and September 30, 2018, TD Group had $20.4 million and $14.1 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $18.6 million and $13.1 million on the effective tax rate at March 30, 2019 and September 30, 2018, respectively. The Company believes the tax positions that comprise the unrecognized tax benefits will be reduced by approximately $2.3 million over the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

11. FAIR VALUE MEASUREMENTS

The following table presents 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):

Table of Contents

The Company values its financial instruments using an industry standard market approach, in which prices and other relevant information are generated by market transactions involving identical or comparable assets or liabilities. No financial instruments were recognized using unobservable inputs.

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 interest rate caps were measured at fair value using implied volatility rates of each individual caplet and the yield curve for the related periods.

The Company’s derivative contracts consist of foreign currency exchange contracts and, from time to time, interest rate swap agreements. These derivative contracts are over-the-counter, and their fair value is determined using modeling techniques that include market inputs such as interest rates, yield curves, and currency exchange rates. These contracts are categorized as Level 2 in the fair value hierarchy.

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 notes were based upon quoted market prices. There has not been any impact to the fair value of derivative liabilities due to the Company's own credit risk. Similarly, there has not been any impact to the fair value of derivative assets based on the Company's evaluation of counterparties' credit risks.

The fair value of cash and cash equivalents, restricted cash, trade accounts receivable-net and accounts payable approximated book value due to the short-term nature of these instruments at March 30, 2019 and September 30, 2018.

12. DERIVATIVES AND HEDGING ACTIVITIES

The Company is exposed to, among other things, the impact of changes in foreign currency exchange rates and 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. These derivative financial instruments do not subject the Company to undue risk, as gains and losses on these instruments generally offset gains and losses on the underlying assets, liabilities, or anticipated transactions that are being hedged. The Company has agreements with each of its swap and cap counterparties that contain a provision whereby if the Company defaults on the credit facility the Company could also be declared in default on its swaps and caps, resulting in an acceleration of payment under the swaps and caps.

All derivative financial instruments are recorded at fair value in the condensed consolidated balance sheets. For a derivative that has not been designated as an accounting hedge, the change in the fair value is recognized immediately through earnings. For a derivative that has been designated as an accounting hedge of an existing asset or liability (a fair value hedge), the change in the fair value of both the derivative and underlying asset or liability is recognized immediately through earnings. For a derivative designated as an accounting hedge of an anticipated transaction (a cash flow hedge), the change in the fair value is recorded on the condensed consolidated balance sheet in accumulated other comprehensive income to the extent the derivative is effective in mitigating the exposure related to the anticipated transaction. The change in the fair value related to the ineffective portion of the hedge, if any, is immediately recognized in earnings. The amount recorded within accumulated other comprehensive income is reclassified into earnings in the same period during which the underlying hedged transaction affects earnings.

Interest Rate Swap and Cap Agreements – Interest rate swap and cap agreements are used to manage interest rate risk associated with floating-rate borrowings under our credit facility. The interest rate swap and cap 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 and cap 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 (loss) income in stockholders’ deficit 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. As the interest rate swap and cap agreements are used to manage interest rate risk, any gains or losses from the derivative instruments that are reclassified into earnings are recognized in interest expense - net in the condensed consolidated statements of income.

Certain derivative asset and liability balances are offset where master netting agreements provide for the legal right of setoff. For classification purposes, we record the net fair value of each type of derivative position that is expected to settle in less than one year with each counterparty as a net current asset or liability and each type of long-term position as a net non-current asset or liability. The amounts shown in the table below represent the gross amounts of recognized assets and liabilities, the amounts offset in the condensed consolidated balance sheet and the net amounts of assets and liabilities presented therein.

⁽¹⁾	Refer to Note 11, "Fair Value Measurements," for the condensed consolidated balance sheet classification of our interest rate swap and cap agreements.

Based on the fair value amounts of the interest rate swap and cap agreements determined as of March 30, 2019, the estimated net amount of existing gains and losses and caplet amortization expected to be reclassified into interest income within the next twelve months is approximately $0.8 million.

Effective September 30, 2016, the Company redesignated the interest rate cap agreements related to the $400 million and the $750 million aggregate notional amount with cap rates of 2.0% and 2.5%, respectively, based on the expected probable cash flows associated with the 2016 term loans and 2015 term loans in consideration of the Company’s ability to select one-month, two-month, three-month, or six-month LIBO rate set forth in the Second Amended and Restated Credit Agreement. Accordingly, amounts previously recorded as a component of accumulated other comprehensive (loss) income in stockholder’s deficit amortized into interest expense was $2.3 million and $2.0 million for the twenty-six week periods ended March 30, 2019 and March 31, 2018, respectively. The accumulated other comprehensive loss to be reclassified

Table of Contents

into interest expense over the remaining term of the cap agreements is $8.7 million with a related tax benefit of $2.0 million as of March 30, 2019.

Effective December 30, 2017, the Company redesignated the existing interest rate swap agreements related to the $750 million, $500 million, $1,000 million and $750 million aggregate notional amounts with swap rates of 5.0%, 4.4%, 4.3% and 5.3%, respectively, based on the expected probable cash flows associated with certain term loans in consideration of the Company’s removal of the LIBO rate floor on the certain term loans as set forth in Amendment No. 4 to the Second Amended and Restated Credit Agreement. Accordingly, the amount recorded as a component of accumulated other comprehensive (loss) income in stockholders’ deficit related to these redesignated interest rate swap hedges will be amortized into earnings based on the original maturity date of the related interest rate swap agreements. Amounts previously recorded as a component of accumulated other comprehensive (loss) income in stockholders' deficit amortized into interest expense was $0.5 million and $0.3 million for the twenty-six week periods ended March 30, 2019 and March 31, 2018. The accumulated other comprehensive income to be reclassified into interest income over the remaining term of the swaps agreements is $1.2 million with a related tax expense of $0.3 million as of March 30, 2019.

Effective March 31, 2018, the Company redesignated the existing interest rate swap agreements related to the $1,000 million and the $400 million aggregate notional amount with swap rates of 4.9% and 4.4%, respectively, based on the expected probable cash flows associated with certain term loans in consideration of the Company’s removal of the LIBO rate floor on the certain term loans as set forth in the refinancing facility agreement dated February 22, 2018 related to the Second Amended and Restated Credit Agreement. Accordingly, the amount recorded as a component of accumulated other comprehensive (loss) income in stockholders’ deficit related to these redesignated interest rate swap hedges will be amortized into earnings based on the original maturity date of the related interest rate swap agreements. Amounts previously recorded as a component of accumulated other comprehensive (loss) income in stockholders' deficit amortized into interest income was $1.4 million for the twenty-six week period ended March 30, 2019. The accumulated other comprehensive income to be reclassified into interest income over the remaining term of the swaps agreements is $10.0 million with a related tax expense of $2.4 million as of March 30, 2019.

Foreign Currency Forward Exchange Contracts – The Company transacts business in various foreign currencies, which subjects the Company’s cash flows and earnings to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. At March 30, 2019, the Company had outstanding foreign currency forward exchange contracts principally to sell U.S. dollars with notional amounts of $415.7 million. These notional values consist primarily of contracts for the British pound sterling, Canadian dollar, and European euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective dates. During the twenty-six week period ended March 30, 2019, the Company recognized gains on foreign currency forward exchange contracts designated as fair value hedges of $0.8 million in cost of sales and $1.0 million in selling and administrative expenses, respectively, in the condensed consolidated statement of income. During the twenty-six week period ended March 30, 2019, the Company reclassified losses on foreign currency forward exchange contracts designated as cash flow hedges of $1.0 million to net sales in the condensed consolidated income statement. The losses were previously recorded as a component of accumulated other comprehensive (loss) income in stockholders' deficit.

During the twenty-six week period ended March 30, 2019, the Company recorded a gain of $1.8 million on foreign currency forward exchange contracts that have not been designated as accounting hedges. These foreign currency exchange gains are included in selling and administrative expenses.

There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the twenty-six week period ended March 30, 2019. In addition, there was no significant impact to the Company’s earnings when a hedged firm commitment no longer qualified as a fair value hedge or when a hedged forecasted transaction no longer qualified as a cash flow hedge during the twenty-six week period ended March 30, 2019.

Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive (loss) income in stockholders' deficit are reclassified into earnings when the hedged transaction settles. The Company expects to reclassify approximately $10.8 million of net losses into earnings over the next 12 months. The maximum duration of the Company’s foreign currency cash flow hedge contracts at March 30, 2019 was 24 months.

Table of Contents

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, specialized AC/DC electric motors and generators, databus and power controls, high performance hoists, winches and lifting devices and cargo loading and handling systems. 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, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes and cargo delivery systems. 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 seat belts and safety restraints for ground transportation applications, mechanical/electro-mechanical actuators and controls for space applications, hydraulic/electromechanical actuators and fuel valves for land based gas turbines, and refueling systems for heavy equipment used in mining, construction and other industries and turbine controls for the energy and oil and gas markets. Primary customers of this segment are off-road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers, manufacturers of heavy equipment used in mining, construction and other industries and turbine original equipment manufacturers, gas pipeline builders and electric utilities.

The Esterline segment includes recently acquired Esterline operations that primarily develop, produce and market products for the aerospace and defense industry specializing in three core business sectors - advanced materials, avionics and controls and sensors and systems. Major product offerings within the advanced materials sector include high-temperature-resistant materials and components used for a wide range of military and commercial aerospace purposes, and combustible ordinance and electronic warfare countermeasure products. Major product offerings within the avionics and controls sector include technology interface systems for commercial and military aircraft and similar devices for land- and sea-based military vehicles, integrated cockpit systems, display technologies for avionics, training and simulation markets, secure communications systems, specialized medical equipment, and other high-end industrial applications. Major product offerings within the sensors and systems sector include high-precision temperature and pressure sensors, specialized harsh-environment connectors, electrical power distribution equipment, and other related systems principally for aerospace and defense customers. Products are primarily sold in the original equipment and aftermarket channels. The assessment of this segment is preliminary as Esterline was acquired during the second quarter of fiscal 2019. Refer to Note 3, "Acquisitions and Divestitures," for further information on the Esterline acquisition. The Esterline segment will be reassessed during the third quarter of fiscal 2019 as the acquisition is expected to be integrated into TransDigm's existing Power & Control, Airframe and Non-aviation segments.

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 recorded as corporate expenses including refinancing costs, acquisition-related costs, transaction-related costs, foreign currency gains and losses, 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. Certain corporate-level expenses are allocated to the operating segments.

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

Forward-looking Statements

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.

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.” When used in this Quarterly Report on Form 10-Q, the words “believe,” “may,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate” or “continue” and other words and terms of similar meaning are intended to identify forward-looking statements. Although the Company believes that its plans, intentions and expectations reflected in or suggested by such forward-looking statements are reasonable, such forward-looking statements are subject to a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements made in this report. Many such factors are outside the control of the Company. Consequently, such forward-looking statements should be regarded solely as our 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. All forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by these 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 geopolitical or other worldwide events; cyber-security threats and natural disasters; 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; increases in raw material costs, taxes and labor costs that cannot be recovered in product pricing; risks and costs associated with our international sales and operations; and other factors. Please refer to the other information included in this Quarterly Report on Form 10-Q and to Item 1A of 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 every 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, databus and power controls, cockpit security components and systems, specialized cockpit displays, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes, high performance hoists, winches and lifting devices, and cargo loading, handling and 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 year 2019, we generated net sales of $1,195.9 million and net income attributable to TD Group of $202.4 million. EBITDA As Defined was $571.8 million, or 47.8% of net sales. See the "Non-GAAP Financial Measures" section 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.

Critical Accounting Policies and Estimates

The preparation and fair presentation of the consolidated unaudited interim financial statements and accompanying notes included in this report are the responsibility of management. The financial statements and footnotes have been prepared in accordance with

Table of Contents

U.S. generally accepted accounting principles for interim financial statements and contain certain amounts that were based upon management’s best estimates, judgments and assumptions that were believed to be reasonable under the circumstances. On an ongoing basis, we evaluate the accounting policies and estimates used to prepare financial statements. Estimates are based on historical experience, judgments and assumptions believed to be reasonable under current facts and circumstances. Actual amounts and results could differ from these estimates used by management.

A comprehensive discussion of the Company’s critical accounting policies and management estimates and significant accounting policies followed in the preparation of the financial statements is included in Item 7 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2018. Other than the adoption of ASC 606, "Revenue from Contracts with Customers," there have been no significant changes in critical accounting policies, management estimates or accounting policies followed since the fiscal year ended September 30, 2018. Refer to Note 4, "Recent Accounting Pronouncements," and Note 5, "Revenue Recognition," for a discussion of accounting standards recently adopted or required to be adopted in the future.

Acquisitions

Recent acquisitions are described in Note 3, “Acquisitions and Divestitures,” to the condensed consolidated financial statements.

The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $15.3 billion for the quarter ended March 30, 2019 and approximately $11.9 billion for the quarter ended March 31, 2018. The increase in the weighted average level of borrowings was primarily due to the activity in the second quarter of fiscal 2019 consisting of the issuance of $4,000 million in 2026 Secured Notes and the activity in the third quarter of fiscal 2018 consisting of the issuance of additional term loans of $700 million (gross) and issuance of $500 million in 6.875% 2026 Notes.

•

Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 24.2% for the quarter ended March 30, 2019 compared to 18.3% for the quarter ended March 31, 2018.

EBITDA As Defined for the Power & Control segment from the acquisition of Extant prior to the application of our core value-driven operating strategies (i.e., obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers) was approximately $16.2 million for the twenty-six week period ended March 30, 2019. Organic EBITDA As Defined for the Power & Control segment increased approximately $84.2 million, an increase of 16.2%, resulting from organic sales growth in defense sales, commercial OEM and commercial aftermarket sales, as well as the application of our three core value-driven operating strategies, and positive leverage on our fixed overhead costs spread over a higher production volume.

EBITDA As Defined for the Airframe segment from the acquisitions of Skandia and Kirkhill prior to the application of our core value-driven operating strategies (i.e., obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers) was approximately $(4.0) million for the twenty-six week period ended March 30, 2019. Including the impact of our core value-driven operating strategies (which are categorized as "organic" improvement), the EBITDA as Defined contribution from the acquisitions of Skandia and Kirkhill was $22.6 million for the twenty-six week period ended March 30, 2019. Organic EBITDA as Defined for the Airframe segment increased approximately $75.1 million, an increase of 21.8%, resulting from organic sales growth in commercial aftermarket sales, defense sales, and commercial OEM sales, as well as the application of our three core value-driven operating strategies, and positive leverage on our fixed overhead costs spread over a higher production volume.

Backlog

As of March 30, 2019, the Company estimated its sales order backlog at $2,188 million, which excludes the sales order backlog of the Esterline businesses, compared to an estimated sales order backlog of $1,869 million as of March 31, 2018. The increase in backlog is due to growth from recent acquisitions and organic growth in the commercial aftermarket, commercial OEM and defense markets. The majority of the purchase orders outstanding as of March 30, 2019 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 30, 2019 may not necessarily represent the actual amount of shipments or sales for any future period.

The sales order backlog associated with the acquired Esterline businesses is currently being assessed by TransDigm management to ensure the reported backlog is in compliance with TransDigm policy and is being computed consistently with that of the existing TransDigm legacy businesses. Therefore, the sales order backlog associated with the Esterline acquisition is excluded from the total sales order backlog reported above as of March 30, 2019.

Foreign Operations

Although we manufacture a significant portion of our products in the United States, we manufacture certain products in Europe, Asia, Canada, Mexico and other countries globally. 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.

Liquidity and Capital Resources

We have historically maintained a capital structure comprising a mix of equity and debt financing. We vary our leverage both to optimize our equity return and to pursue acquisitions. We expect to meet our current debt obligations as they come due through internally generated funds from current levels of operations and/or through refinancing in the debt markets prior to the maturity dates of our debt.

We continually evaluate our debt facilities to assess whether they most efficiently and effectively meet the current and future needs of our business. The Company evaluates from time to time the appropriateness of its current leverage, taking into consideration the Company’s debt holders, equity holders, credit ratings, acquisition opportunities and other factors.

If the Company has excess cash, it generally prioritizes allocating the excess cash in the following manner: (1) capital spending at existing businesses, (2) acquisitions of businesses, (3) payment of a special dividend and/or repurchases of our common stock and (4) prepayment of indebtedness or repurchase of debt. Whether the Company undertakes common stock repurchases or other aforementioned activities will depend on prevailing market conditions, the Company's liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. In addition, the Company may issue additional debt if prevailing market conditions are favorable to doing so.

The Company’s ability to make scheduled interest payments on, or to refinance, the Company’s indebtedness, or to fund non-acquisition related capital expenditures and research and development efforts, will depend on the Company’s ability to generate

Table of Contents

cash in the future. This is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond its control.

As a result of the debt financing activity during the second quarter of fiscal 2019, interest payments will increase going forward in accordance with the terms of the related debt agreements. However, in connection with the continued 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), we expect our efforts will continue to generate strong margins and provide more than sufficient cash provided by operating activities to meet our interest obligations and liquidity needs. We believe our cash provided by operating activities and available borrowing capacity will enable us to make opportunistic investments in our own stock, make strategic business combinations and/or pay dividends to our shareholders.

Operating Activities. The Company generated $453.0 million of net cash from operating activities during the twenty-six week period ended March 30, 2019 compared to $453.7 million during the twenty-six week period ended March 31, 2018.

The change in accounts receivable during the twenty-six week period ended March 30, 2019 was a use of cash of $7.2 million compared to a source of cash of $5.9 million during the twenty-six week period ended March 31, 2018. The decrease in the source of cash of $13.1 million is primarily attributable to an increase in sales and related timing of receipt of payment from customers.

The change in inventories during the twenty-six week period ended March 30, 2019 was a use of cash of $45.2 million compared to a use of cash of $16.3 million during the twenty-six week period ended March 31, 2018. The increase in the use of cash of $28.8 million is primarily attributable to an increase in raw materials and work in process inventory in response to the growth in the sales order backlog.

The change in accounts payable during the twenty-six week period ended March 30, 2019 was a source of cash of $1.1 million compared to a use of cash of $0.6 million during the twenty-six week period ended March 31, 2018.

Investing Activities. Net cash used in investing activities was $3,612.8 million during the twenty-six week period ended March 30, 2019, consisting of capital expenditures of $43.4 million and payments for acquisitions, net of cash acquired, of $3,569.4 million which is primarily comprised of the acquisitions of Esterline for $3,536.3 million and NavCom for $27.0 million.

Net cash used in investing activities was $23.5 million during the twenty-six week period ended March 31, 2018 consisting of capital expenditures of $30.9 million, and payments for acquisitions of $50.3 million which primarily consisted of the Kirkhill acquisition. The uses of cash related to investing activities was partially offset by the cash proceeds received from the sale of Schroth of $57.7 million.

Financing Activities. Net cash provided by financing activities during the twenty-six week period ended March 30, 2019 was $3,914.8 million. The source of cash was primarily attributable to $4,482.0 million in net proceeds from the completion of the 2026 Secured Notes and 2027 Notes offerings in the second quarter of fiscal 2019 and $47.1 million in proceeds from stock option exercises. Sources were partially offset by the cash tender and redemption of the 2020 Notes for $550.0 million, repayments on term loans of $38.2 million, and the payment of $24.3 million in dividend equivalent payments.

Net cash used in financing activities during the twenty-six week period ended March 31, 2018 was $72.0 million. The use of cash was primarily related to the payment of $56.1 million in dividend equivalent payments and $34.5 million in debt service payments on existing term loans, partially offset by $26.3 million in proceeds from stock option exercises.

Description of Senior Secured Term Loans and Indentures

Senior Secured Term Loans Facility

TransDigm has $7,561.7 million in fully drawn term loans (the “Term Loans Facility”) and a $760.0 million revolving credit facility. The Term Loans Facility consists of three tranches of term loans as follows (aggregate principal amount disclosed is as of March 30, 2019):



Term Loans Facility	Aggregate Principal	Maturity Date	Interest Rate
Tranche E	$2,232.4 million	May 30, 2025	LIBO rate + 2.5%
Tranche F	$3,542.0 million	June 9, 2023	LIBO rate + 2.5%
Tranche G	$1,787.3 million	August 22, 2024	LIBO rate + 2.5%

The Term Loans Facility requires quarterly aggregate principal payments of $19.1 million. The revolving commitments consist of two tranches which includes up to $151.5 million of multicurrency revolving commitments. At March 30, 2019, the Company had $33.7 million in letters of credit outstanding and $726.3 million in borrowings available under the revolving commitments.

The interest rates per annum applicable to the loans under the Credit Agreement are, 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,

Table of Contents

nine or twelve-month) interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted LIBO rate related to the tranche E, tranche F and tranche G term loans are not subject to a floor. For the twenty-six week period ended March 30, 2019, the applicable interest rates ranged from approximately 4.7% to 5.0% on the existing term loans. Interest rate swaps and caps used to hedge and offset, respectively, the variable interest rates on the credit facility are described in Note 12, “Derivatives and Hedging Activities,” to the condensed consolidated financial statements.

Recent Amendments to the Credit Agreement

On November 30, 2017, the Company entered into Amendment No. 4 to the Second Amended and Restated Credit Agreement (“Amendment No. 4”). Pursuant to Amendment No. 4, TransDigm, among other things, converted approximately $798.2 million of existing tranche D term loans into additional tranche F term loans and decreased the margin applicable to the existing tranche E term loans and tranche F term loans to LIBO rate plus 2.75% per annum and also removed the LIBO rate floor of 0.75%. The terms and conditions (other than maturity date and pricing) that apply to the tranche F term loans are substantially the same as the terms and conditions that apply to the tranche D term loans immediately prior to Amendment No. 4.

On February 22, 2018, the Company entered into a refinancing facility agreement to the Second Amended and Restated Credit Agreement. TransDigm, among other things, incurred new tranche G term loans in an aggregate principal amount equal to $1,809 million and repaid in full all of the existing tranche G term loans outstanding under the Second and Amended Restated Credit Agreement immediately prior to the refinancing facility agreement. The refinancing facility agreement also decreased the margin applicable to the tranche G term loans to LIBO rate plus 2.5% per annum. The terms and conditions that apply to the tranche G term loans, excluding pricing, are substantially the same as the terms and conditions that apply to the tranche G term loans immediately prior to the refinancing facility agreement.

On May 30, 2018, the Company entered into Amendment No. 5 to the Second Amended and Restated Credit Agreement ("Amendment No. 5"). Pursuant to Amendment No. 5, TransDigm, among other things, incurred new tranche E term loans in an aggregate principal amount equal to $1,322.0 million, and repaid in full all of the existing tranche E term loans outstanding under the Second Amended and Restated Credit Agreement immediately prior to Amendment No. 5. The Company also incurred incremental tranche E term loans in an aggregate principal amount equal to $933.0 million. The new tranche E term loans and incremental tranche E term loans mature on May 30, 2025. Amendment No. 5 also decreased the margin applicable to the new tranche E term loans to LIBO rate plus 2.5% per annum. The terms and conditions that apply to the tranche E term loans, other than the maturity date and margin, are substantially the same as the terms and conditions that apply to the tranche E term loans immediately prior to Amendment No. 5.

Additionally, pursuant to Amendment No. 5, the Company incurred new tranche F term loans in an aggregate principal amount equal to $3,577.7 million, and repaid in full all of the existing tranche F term loans outstanding under the Second and Amended Restated Credit Agreement immediately prior to Amendment No. 5. Amendment No. 5 also decreased the margin applicable to the tranche F term loans to LIBO rate plus 2.5% per annum.

Under the terms of Amendment No. 5, the maturity date of the existing $600.0 million revolving credit facility was extended to December 28, 2022. The terms and conditions that applied to the revolving credit facility upon execution of Amendment No. 5 , other than the maturity date, were substantially the same as the terms and conditions that applied to the revolving credit facility immediately prior to Amendment No. 5.

Amendment No. 5 extended our ability to make certain additional restricted payments (including the ability of the Company to declare or pay dividends or repurchase stock) in an aggregate amount not to exceed $1.5 billion, so long as, among other conditions, the consolidated secured net debt ratio is no greater than 4.00 to 1.00 (in the case of share repurchases) or the consolidated net leverage ratio is no greater than 6.75 to 1.00 (in the case of dividends or other distributions), in each case, after giving pro forma effect to such transactions. As there were no dividends or share repurchases paid prior to December 31, 2018, up to $500 million may be used to repurchase stock in future periods. No share repurchases were made during the quarter ended March 30, 2019.

On March 14, 2019, the Company entered into Amendment No. 6 to the Second Amended and Restated Credit Agreement ("Amendment No. 6"). Under the terms of Amendment No. 6, the capacity of the revolving credit facility increased from $600 million to $760 million. The revolving commitments consist of two tranches which include up to $151.5 million of multicurrency revolving commitments. The terms and conditions that apply to the revolving credit facility, other than the additional revolving credit commitments, are substantially the same as the terms and conditions that applied to the revolving credit facility immediately prior to Amendment No. 6.

The Notes do not require principal payments prior to their maturity. Interest under the Notes is payable semi-annually. The Notes represent our unsecured obligations ranking subordinate to our senior debt, as defined in the applicable indentures.

The Notes are subordinated to all of our existing and future senior debt, rank equally with all of our existing and future senior subordinated debt and rank senior to all of our future debt that is expressly subordinated to the Notes. The TransDigm Inc. Notes are guaranteed on a senior subordinated unsecured basis by TD Group and TransDigm Inc.'s domestic restricted subsidiaries. The TransDigm UK Notes are guaranteed on a senior subordinated basis by TransDigm Inc., TD Group and TransDigm Inc.'s domestic restricted subsidiaries. The guarantees of the 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 Notes. The Notes are structurally subordinated to all of the liabilities of TD Group’s non-guarantor subsidiaries. The Notes contain many of the restrictive covenants included in the Credit Agreement. TransDigm is in compliance with all of the covenants contained in the Notes.

During the third quarter of fiscal 2018, TransDigm UK, a wholly-owned, indirect subsidiary of TD Group, issued $500 million in aggregate principal amount of the TransDigm UK Notes at a discount of 0.76%. The TransDigm UK Notes bear interest at the rate of 6.875% per annum and mature on May 15, 2026.

On January 30, 2019, the Company entered into a purchase agreement in connection with a private offering of $3.8 billion aggregate principal amount in 6.25% senior secured notes due 2026. In addition, on February 1, 2019, the Company entered into a purchase agreement in connection with a private offering of $200 million aggregate principal amount of 6.25% senior secured notes due 2026. All $4.0 billion aggregate principal amount of the secured notes will constitute a single class and was issued under a single indenture (herein the "2026 Secured Notes"). The notes in the first secured notes offering were issued at a price of 100% of their principal amount and the notes in the second secured notes offering were issued at a price of 101% of their principal amount. The Notes are guaranteed, with certain exceptions, by TransDigm Group, TransDigm UK and all of TransDigm Inc.’s existing U.S. subsidiaries on a senior secured basis. The 2026 Secured Notes offerings closed on February 13, 2019 and mature on March 15, 2026.

On February 13, 2019, the Company announced a cash tender offer for any and all of its outstanding 2020 Notes. On March 15, 2019, the Company redeemed the principal amount of $550 million in 2020 Notes, plus accrued and unpaid interest of approximately $12.6 million. The Company recorded refinancing costs of $1.7 million during the thirteen and twenty-six week periods ended March 30, 2019 representing unamortized debt issuance costs expensed in conjunction with the redemption of the 2020 Notes.

On March 14, 2019, in connection with the closing of the acquisition of Esterline, the Company announced a cash tender offer for any and all of its outstanding 2023 Notes. A notice of redemption with respect to the Notes was given to each holder of the Notes, providing for the redemption of all outstanding Notes on April 15, 2019 at the redemption price set forth in the indenture. On April 15, 2019, the Company redeemed the principal amount of approximately $373.8 million (€330.0 million as the 2023 Notes were denominated in Euros), plus accrued interest of approximately $6.8 million, the early redemption premium of $6.8 million and fees of approximately $0.2 million. As of March 30, 2019, the funds for the redemption of the 2023 Notes of approximately $387.6

Table of Contents

million were held in trust and are committed to be used in redeeming the 2023 Notes. The funds are restricted to the redemption of the 2023 Notes, and as such, are reflected as restricted cash in the condensed consolidated balance sheet as of March 30, 2019.

Certain Restrictive Covenants in Our Debt Documents

The Credit Agreement and the Indentures governing the Notes contain restrictive covenants that, among other things, limit the incurrence of additional indebtedness, the payment of special dividends, transactions with affiliates, asset sales, acquisitions, mergers and consolidations, liens and encumbrances, and prepayments of certain other indebtedness.

The restrictive covenants included in the Credit Agreement are subject to amendments executed periodically. The most recent amendment that impacted the restrictive covenants contained in the Credit Agreement is Amendment No. 6. The restrictive covenants are described above in the Recent Amendments to the Credit Agreement section.

Under the terms of the Credit Agreement, TransDigm is entitled, on one or more occasions, to request additional term loans or additional revolving commitments to the extent that the existing or new lenders agree to provide such incremental term loans or additional revolving commitments provided that, among other conditions, our consolidated net leverage ratio would be no greater than 7.25 to 1.00 and the consolidated secured net debt ratio would be no greater than 5.00 to 1.00, in each case, after giving effect to such incremental term loans or additional revolving commitments.

The Credit Agreement requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as defined in the Credit Agreement), commencing 90 days after the end of each fiscal year, 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 Credit Agreement 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. No matters mandating prepayments occurred during the quarter ended March 30, 2019.

In addition, under the Credit Agreement, if the usage of the revolving credit facility exceeds 25% of the total revolving commitments, the Company will be required to maintain a maximum consolidated net leverage ratio of net debt, as defined, to trailing four-quarter EBITDA As Defined. 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 Agreement or the Indentures.

If any such default occurs, the lenders under the Credit Agreement 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 Agreement 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 Agreement, 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.

As of March 30, 2019, the Company was in compliance with all of its debt covenants.

Trade Receivables Securitization

During fiscal 2014, the Company established a trade receivable securitization facility (the “Securitization Facility”). The Securitization Facility effectively increases the Company’s borrowing capacity depending on the amount of the domestic operations’ trade accounts receivable. The Securitization Facility includes the right for the Company to exercise annual 1 year extensions as long as there have been no termination events as defined by the agreement. The Company uses the proceeds from the Securitization Facility as an alternative to other forms of debt, effectively reducing borrowing costs.

On July 31, 2018, the Company amended the Securitization Facility to increase the borrowing capacity to $350 million and extend the maturity date to July 31, 2019. As of March 30, 2019, the Company has borrowed $300 million under the Securitization Facility. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.

Stock Repurchase Program

On November 8, 2017, our Board of Directors, authorized a stock repurchase program permitting repurchases of our outstanding shares not to exceed $650 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes. No repurchases were made under the program during the quarter and year-to-date period ended March 30, 2019. As of March 30, 2019, the entire $650 million of repurchases allowable under the program remained, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.

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.

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.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The information called for by this item is provided under the caption 'Description of Senior Secured Credit Facilities and Indentures' under Item 2 - "Management's Discussion and Analysis of Financial Condition and Results of Operations." Market risks are described more fully within “Quantitative and Qualitative Disclosures About Market Risk” in Part II, Item 7A of our most recent Form 10-K. These market risks have not materially changed since the date our most recent Form 10-K was filed with the SEC.

ITEM 4. CONTROLS AND PROCEDURES

As of March 30, 2019, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its President, Chief Executive Officer and Director (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the President, Chief Executive Officer and Director 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 President, Chief Executive Officer and Director 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. During the fiscal quarter ended March 30, 2019, the Company completed the acquisition of Esterline. The Company is currently integrating the acquisition into its operations, compliance programs and internal control processes. As permitted by SEC rules and regulations, the Company has excluded the acquisition from management's evaluation of internal controls over financial reporting as of March 30, 2019. The acquisition constituted approximately 33% of the Company's total assets (inclusive of acquired intangible assets) as of March 30, 2019, and approximately 10% of the Company's net sales in the fiscal quarter ended March 30, 2019.

Changes in Internal Control over Financial Reporting

Except as described in the preceding paragraph, there was no change in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended March 30, 2019, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We and certain of our current or former officers and directors are defendants in a consolidated securities class action captioned In re TransDigm Group, Inc. Securities Litigation, Case No. 1:17-cv-01677-DCN (N.D. Ohio). The cases were originally filed on August 10, 2017, and September 18, 2017 and were consolidated on December 5, 2017. A consolidated amended complaint was filed on February 16, 2018. The plaintiffs allege that the defendants made false or misleading statements with respect to, or failed to disclose, the impact of certain alleged business practices in connection with sales to the U.S. government on the Company’s growth and profitability. The plaintiffs assert claims under Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder and Section 20(a) of the Exchange Act, and seek unspecified monetary damages and other relief. In addition, we, as nominal defendant, and certain of our current or former officers and directors are defendants in a shareholder derivative action captioned Sciabacucchi v. Howley et al., No. 1:17-cv-1971-DCN (N.D. Ohio). The case was filed on September 19, 2017. The plaintiffs allege breach of fiduciary duty and other claims arising out of substantially the same actions or inactions alleged in the securities class actions described above. This action has been stayed pending the outcome of a motion to dismiss on the securities class action. Although we are only a nominal defendant in the derivative action, we could have indemnification obligations and/or be required to advance the costs and expenses of the officer and director defendants in the action.

We intend to vigorously defend these matters and believe they are without merit. We also believe we have sufficient insurance coverage available for these matters. Therefore, we do not expect these matters to have a material adverse impact on our financial condition or results of operations. However, given the preliminary status of the litigation, it is difficult to predict the likelihood of an adverse outcome or estimate a range of any potential loss.

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, 2018, filed on November 9, 2018. 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 November 8, 2017, our Board of Directors, authorized a stock repurchase program permitting repurchases of our outstanding shares not to exceed $650 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes. No repurchases were made under the program during the thirteen and twenty-six week periods ended March 30, 2019. As of March 30, 2019, the entire $650 million of repurchases allowable under the program remained, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.
