NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THIRTEEN WEEK PERIOD S ENDED DECEMBER 28, 2019 AND DECEMBER 29, 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, advanced sensor products, switches and relay panels, advanced displays, thermal protection and insulation, lighting and control technology, military personnel parachutes, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems.

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, 2019 included in TD Group’s Form 10-K filed on November 19, 2019 . As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“US GAAP”). The September 30, 2019 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the thirteen week period ended December 28, 2019 are not necessarily indicative of the results to be expected for the full year.

Certain prior year amounts have been reclassified to conform to the current year presentation.

3. ACQUISITIONS AND DIVESTITURES

During the fiscal year ended September 30, 2019 , the Company completed the acquisitions of Esterline Technologies Corporation ("Esterline") and substantially all of the assets and technical data rights of the Stormscope product line from L3Harris Technologies, Inc. ("Stormscope") and NavCom Defense Electronics ("NavCom"). 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 December 28, 2019 , the one year measurement period is open for Esterline and Stormscope; 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 acquisitions strengthen and expand the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies (obtaining profitable new business, improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for each acquisition reflects the current earnings before interest, taxes, depreciation and amortization (EBITDA) and cash flows, as well as the future EBITDA and cash flows expected to be generated by the business, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 25 to 30 years .

Table of Contents

Acquisitions

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 for the redemption of the outstanding senior notes due 2023 (herein the "2023 Notes"). The 2023 Notes were redeemed on April 15, 2019. Esterline, through its subsidiaries, was an industry leader in specialized manufacturing for the aerospace and defense industry 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. TransDigm evaluated the strategic fit and description of each Esterline reporting unit to determine the appropriate business segment for the reporting unit. Each Esterline reporting unit is included in one of TransDigm's segments: Power and Control, Airframe, or Non-aviation. Refer to Note 13, "Segments," for additional information about 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. Allocations are based on the acquisition method of accounting and in-process third-party valuation appraisals. Given the complexity of the Esterline acquisition, the allocation of the purchase price is preliminary and will be finalized by the end of the one year measurement period permissible under US GAAP.

Except where otherwise noted in the notes to the 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.

The preliminary allocation of the fair value of the Esterline acquisition as of the acquisition date of March 14, 2019 is summarized in the table below (presented in millions).

Assets acquired:
Trade accounts receivable	$ 387
Inventories	589
Prepaid expenses and other	422
Property, plant, and equipment	469
Other intangible assets	1,300
Goodwill	2,190
Other	22
Total assets acquired	5,379
Liabilities assumed:
Accounts payable	146
Accrued liabilities	715
Other non-current liabilities	594
Total liabilities assumed	1,455
Net assets acquired	$ 3,924

The Company currently expects that of the approximately $ 2.2 billion of goodwill recognized for the acquisition, approximately $ 25.6 million will be deductible for tax purposes. Also, of the approximately $ 1.3 billion of other intangible assets recognized for the acquisition, the Company currently expects that approximately $ 48.9 million will be deductible for tax purposes.

In connection with the Esterline acquisition, we acquired existing long-term contracts with customers that were incurring gross margin losses as of the date of acquisition. Based on our review of these contracts, we concluded that the terms of certain contracts were unfavorable when compared to market terms as of the acquisition date. As a result, we recognized loss contract reserves as of the acquisition date of $ 268.4 million based on the present value of the difference between the contractual cash flows of the existing long-term contracts and the estimated cash flows had the contracts been executed at market terms as of the acquisition date. As of September 30, 2019 , we reclassified $ 9.3 million in loss contract reserves to liabilities held-for-sale, as it pertained to Souriau-Sunbank. Significant assumptions used to determine the fair value of the loss contract reserves using the discounted cash flow model include discount rates, forecasted quantities of products to be sold under the long-term contracts and market prices for respective products. These significant assumptions are

forward looking and could be affected by future economic and market conditions. The loss contract reserves are amortized and recorded as an offset to cost of sales over the life of the contracts as actual sales occur under the long-term contracts. Approximately $ 9.1 million was amortized and recorded as an offset to cost of sales in the condensed consolidated statement of income for the thirteen week period ended December 28, 2019 . Total loss contract reserves related to the Esterline acquisition are $ 222.5 million and $ 231.8 million at December 28, 2019 and September 30, 2019 , respectively, of which $ 71.9 million and $ 60.0 million is classified in accrued liabilities and $ 150.6 million and $ 171.8 million is classified in other non-current liabilities in the condensed consolidated balance sheets at December 28, 2019 and September 30, 2019 , respectively.

Extant Acquisitions – On August 30, 2019, the Company's Extant subsidiary completed the acquisition of substantially all of the assets and technical data rights of the Stormscope product line from L3Harris Technologies, Inc. for approximately $ 20 million in cash. Stormscope is a lightning detection system for the general aviation and business jet markets. Stormscope is included as a product line of Extant, which is included in TransDigm's Power and Control segment. The Company expects that approximately $ 11.1 million of goodwill recognized for the acquisition and approximately $ 7.5 million of other intangible assets recognized for the acquisition will be deductible for tax purposes over 15 years.

On October 1, 2018, the Company's Extant subsidiary completed the acquisition of substantially all of the assets and technical data rights from the Corona, California operations of NavCom for approximately $ 27 million in cash. 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. Approximately $ 9.0 million of goodwill recognized for the acquisition is deductible for tax purposes over 15 years.

Pro forma net sales and results of operations for the Extant acquisitions had they occurred at the beginning of the applicable thirteen week periods ended December 28, 2019 or December 29, 2018 are not material and, accordingly, are not provided.

Divestitures

Souriau-Sunbank – On December 20, 2019, TransDigm completed the divestiture of the Souriau-Sunbank Connection Technologies business (“Souriau-Sunbank”) with Eaton Corporation plc (“Eaton”) for approximately $ 920 million . Souriau-Sunbank was acquired by TransDigm as part of its acquisition of Esterline in March 2019.

Esterline Interface Technology Group – On September 20, 2019, TransDigm completed the divestiture of its Esterline Interface Technology (“EIT”) group of businesses to an affiliate of KPS Capital Partners, LP for approximately $ 190 million . EIT was acquired by TransDigm as part of its acquisition of Esterline in March 2019.

Refer to Note 18, "Discontinued Operations," for further information on the Company's divestitures.

4. RECENT ACCOUNTING PRONOUNCEMENTS

In February 2016, the FASB issued ASU 2016-02, “Leases (ASC 842),” which requires lessees to recognize a right-of-use asset and lease liability for all leases with a term of more than 12 months. ASU 2016-02 was effective for the Company on October 1, 2019, and required a modified retrospective application. In July 2018, the FASB issued ASU 2018-11, “Leases (ASC 842) Targeted Improvements,” which provided an additional transition method that allowed entities to initially apply the new standard at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption without restating prior periods. The Company has completed the necessary changes to the consolidated financial statements and related disclosures, internal controls, financial policies and information systems. On October 1, 2019, the Company adopted ASC 842 and related amendments using the modified retrospective method. Results for reporting periods beginning after October 1, 2019, are presented under ASC 842, while prior period amounts continue to be reported under ASC 840, “Leases." The Company elected to apply the package of practical expedients permitted within the new standard, which among other things, allows the carry forward of historical lease classification of existing leases. Additionally, the adoption of the new standard resulted in the recording of lease assets and lease liabilities for operating leases of $ 99 million and $ 105 million , respectively, as of October 1, 2019. The effects of our transition to ASC 842 resulted in no cumulative adjustment to retained earnings in the period of adoption. The adoption of the standard did not have a material impact on our condensed consolidated statements of income or cash flows. Refer to Note 16, "Leases," for additional information.

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 the Company for annual and interim periods beginning after October 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.

Table of Contents

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 the Company for fiscal years beginning after October 1, 2020, 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 December 2019, the FASB issued ASU 2019-12, “Income Taxes (ASC 740) - Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify US GAAP for other areas of ASC 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments is permitted, including adoption in any interim period for which financial statements have not yet been issued. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis.

5. REVENUE RECOGNITION

TransDigm's sales are concentrated in the aerospace industry. The Company’s customers include: distributors of aerospace components, commercial airlines, large commercial transport and regional and business aircraft OEMs, various armed forces of the United States and friendly foreign governments, defense OEMs, system suppliers, and various other industrial customers .

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

In some contracts, the Company found that 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. Therefore, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use.

Based on our production cycle, it is generally expected that goods related to the revenue 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.

Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in the condensed 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 are expensed as incurred. These costs are reported as a component of selling and administrative expenses in the unaudited condensed consolidated statements of income.

Accrued interest, which is classified as a component of accrued liabilities, was $ 181.0 million and $ 92.6 million as of December 28, 2019 and September 30, 2019 , respectively.

Issuance of Senior Subordinated Notes due 2027 – On October 29, 2019, the Company entered into a purchase agreement in connection with a private offering of $ 2,650 million in new 5.50 % senior subordinated notes due 2027 (herein the "5.50% 2027 Notes"). The 5.50% 2027 Notes were issued pursuant to an indenture, dated as of November 13, 2019, among TransDigm, as issuer, TransDigm Group, TransDigm 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 5.50% 2027 Notes bear interest at the rate of 5.50 % per annum, which accrues from November 13, 2019 and is payable in arrears on May 15th and November 15th of each year, commencing on May 15, 2020. The 5.50 % 2027 Notes mature on November 15, 2027, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indenture.

The Company capitalized $ 23.6 million and expensed $ 1.1 million of refinancing costs representing debt issuance costs associated with the 5.50 % 2027 Notes during the thirteen week period ended December 28, 2019 .

Repurchase of Senior Subordinated Notes due 2022 – On October 29, 2019, the Company announced a cash tender offer for any and all of its 2022 Notes outstanding. On November 26, 2019, the Company redeemed the principal amount of $ 1,150 million , plus accrued interest of approximately $ 25.5 million and early redemption premium of $ 17.3 million .

The Company wrote off $ 3.8 million in unamortized debt issuance costs during the thirteen week period ended December 28, 2019 in conjunction with the redemption of the 2022 Notes.

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 Electronics, which is a subsidiary of TransDigm. These obligations were assumed in connection with the Esterline acquisition and the balance was $ 31.3 million at December 28, 2019 and $ 39.2 million at September 30, 2019 . The decrease in the obligation is attributable to a purchase accounting adjustment recorded in the first quarter of fiscal 2020 as permissible within the one year measurement period related to the acquisition of Esterline.

Obligations under Finance Leases - The Company leases certain buildings and equipment under finance leases. These obligations were 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 $ 51.9 million at December 28, 2019 and $ 49.9 million at September 30, 2019 . Refer to Note 16, "Leases," for further disclosure on the Company's finance lease obligations.

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 December 28, 2019 and December 29, 2018 , the effective income tax rate was 20.1 % and 21.5 % , respectively. The Company's lower

Table of Contents

effective tax rate for the thirteen week period ended December 28, 2019 was primarily due to a discrete benefit recognized for excess tax benefits for share-based payments during the thirteen week period ended December 28, 2019 , partially offset by an increase in the valuation allowance associated with our net interest expense limitation under IRC Section 163(j). The Company's effective tax rate for the thirteen week period ended December 28, 2019 was lower than the Federal statutory rate of 21 % primarily due to the discrete benefit recognized for excess tax benefits for share-based payments and the benefit associated with the deduction for foreign-derived intangible income (FDII), partially offset by the increase in the valuation allowance attributed to our net interest expense limitation under IRC Section 163(j), and our foreign earnings taxed at rates higher than the U.S. statutory rate. The Company’s effective tax rate for the thirteen week period ended December 29, 2018 was slightly higher than the Federal statutory tax rate primarily resulting from the valuation allowance associated with our net interest expense limitation under IRC Section 163(j), foreign earnings taxed at rates higher than the U.S. statutory rate, partially offset by the benefit associated with FDII.

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 examination for its federal income taxes in the U.S. for fiscal 2016, in Belgium for fiscal years 2016 through 2018, in Canada for fiscal years 2013 through 2015, in France for fiscal years 2015 through 2018, and in Germany for fiscal years 2014 through 2017. The Company is no longer subject to U.S. federal examinations for years before fiscal year 2015. The Company is subject to state income tax examinations for fiscal years 2009 and later.

At December 28, 2019 and September 30, 2019 , TD Group had $ 36.6 million and $ 36.5 million , respectively, in unrecognized tax benefits, the recognition of which would have an effect of approximately $ 31.9 million and $ 31.4 million on the effective tax rate at December 28, 2019 and September 30, 2019 , respectively. The Company believes the tax positions that comprise the unrecognized tax benefits will be reduced by approximately $ 1.5 million over the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of 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 millions):

	Level	December 28, 2019 — Carrying Amount	Fair Value	September 30, 2019 — Carrying Amount	Fair Value

(3) Included in accrued liabilities on the condensed consolidated balance sheets.

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

(5) The carrying amount of the debt instrument is presented net of debt issuance costs, premium and discount. Refer to Note 9, "Debt," for gross carrying amounts.

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.

Table of Contents

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 and cap 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 December 28, 2019 and September 30, 2019 .

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 US GAAP. For these cash flow hedges, the effective portion of the gain or loss from the financial instruments was initially reported as a component of accumulated other comprehensive income (loss) in stockholders’ 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.

$ 400	9/30/2022	6/28/2024	Tranche G	5.5% (3.0% plus the 2.5% margin percentage)

The following table summarizes the Company's interest rate cap agreements:

Aggregate Notional Amount (in millions)	Start Date	End Date	Related Term Loans	Offsets Variable Rate Debt Attributable to Fluctuations Above:
$ 750	9/30/2015	6/30/2020	Tranche E	Three month LIBO rate of 2.5%
$ 750	6/30/2020	6/30/2022	Tranche E	Three month LIBO rate of 2.5%
$ 400	6/30/2016	6/30/2021	Tranche F	Three month LIBO rate of 2.0%
$ 400	12/30/2016	12/31/2021	Tranche G	Three month LIBO rate of 2.5%

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 (in millions).

	December 28, 2019 — Asset	Liability		September 30, 2019 — Asset	Liability
Interest rate cap agreements	$ 1	$ —		$ 1	$ —
Interest rate swap agreements (1)	—	( 183	)	—	( 216	)
Net derivatives as classified in the balance sheet (2)	$ 1	$ ( 183	)	$ 1	$ ( 216	)

(1) The decrease in the interest rate swap liability is primarily attributable to a upward trend in the LIBO rate during the first quarter of fiscal 2020.

(2) 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 December 28, 2019 , the estimated net amount of existing gains and losses and caplet amortization expected to be reclassified into interest expense within the next twelve months is approximately $ 17.0 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 income (loss) in stockholder’s deficit amortized into interest expense was $ 5.0 million and $ 1.1 million for the thirteen week period s ended December 28, 2019 and December 29, 2018 , respectively.

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 December 28, 2019 , the Company had outstanding foreign currency forward exchange contracts principally to sell U.S. dollars with notional amounts of $ 191.9 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 thirteen week period ended December 28, 2019 , the the Company recognized gains on foreign currency forward exchange contracts designated as fair value hedges of $ 0.2 million in cost of sales in the condensed consolidated statement of income. During the thirteen week period ended December 28, 2019 , the gains the Company reclassified on foreign currency forward exchange contracts designated as cash flow hedges in the condensed consolidated income statement are immaterial. The gains (losses) were previously recorded as a component of accumulated other comprehensive income (loss) in stockholders' deficit.

During the thirteen week period ended December 28, 2019 , the Company recorded a loss of $ 0.4 million on foreign currency forward exchange contracts that have not been designated as accounting hedges. These foreign currency exchange losses are included in selling and administrative expenses.

There was an immaterial impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the thirteen week period ended December 28, 2019 . In addition, there was an immaterial 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 thirteen week period ended December 28, 2019 .

Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive income (loss) in stockholders' deficit are reclassified into earnings when the hedged transaction settles. The Company expects to reclassify approximately $ 3.0 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 December 28, 2019 was 24 months.

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, advanced displays, thermal protection, 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 headsets for high-noise, medium-noise, and dismounted applications, 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 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 incentive 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 US 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 US 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 immaterial for the periods presented below. Certain corporate-level expenses are allocated to the operating segments.

16. LEASES

The Company leases certain manufacturing facilities, offices, land, equipment and vehicles. Such leases, some of which are noncancelable and, in many cases, include renewals, expire at various dates. Such options to renew are included in the lease term when it is reasonably certain that the option will be exercised. The Company’s lease agreements typically do not contain any significant residual value guarantees or restrictive covenants, and payments within certain lease agreements are adjusted periodically for changes in an index or rate.

The Company determines if an arrangement is a lease at inception. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The discount rate implicit within our leases is generally not determinable and therefore we determine the discount rate based on our incremental borrowing rate. The incremental borrowing rate for our leases is determined based on the lease term and the currency in which lease payments are made. The length of a lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The Company made an accounting policy election to not recognize lease assets or liabilities for leases with a term of 12 months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease.

20. SUBSEQUENT EVENTS

On January 7, 2020 , the Company paid $ 1.9 billion in special dividends and dividend equivalent payments in connection with the Board of Directors' authorization and declaration of a special cash dividend of $ 32.50 on each outstanding share of common stock and cash dividend equivalent payments on vested options outstanding under its stock incentive plans on December 20, 2019 . These special dividends and dividend equivalent payments were funded by existing cash on hand and the proceeds received from the completed Souriau-Sunbank divestiture. As of December 28, 2019 , approximately $ 1.9 billion was accrued for the special dividend and dividend equivalent payments in accrued liabilities in the condensed consolidated balance sheets.

On January 22, 2020, TransDigm announced its intention to (i) reprice its existing tranche E terms loans, tranche F term loans and tranche G term loans and (ii) extend the maturity date of its existing tranche F term loans, in each case from existing and new lenders under the senior secured credit facilities. In connection with the repricing, TransDigm may also make certain other modifications to the terms of the senior secured credit facilities.

Changes in Results of Operations

Thirteen week period ended December 28, 2019 compared with the thirteen week period ended December 29, 2018

Total Company

• Net Sales . Net organic sales and acquisition sales and the related dollar and percentage changes for the thirteen week period s ended December 28, 2019 and December 29, 2018 were as follows (amounts in millions):

	Thirteen Week Periods Ended — December 28, 2019	December 29, 2018	Change	% Change Total Sales
Organic sales	$ 1,080	$ 993	$ 87	8.7 %
Acquisition sales	385	—	385	38.8 %
	$ 1,465	$ 993	$ 472	47.5 %

The increase in organic sales for the thirteen week period ended December 28, 2019 compared to the thirteen week period ended December 29, 2018 , is primarily related to an increase in commercial aftermarket sales ( $43 million , an increase of 13.0% ), defense sales ( $40 million , an increase of 11.0% ), and commercial OEM sales ( $2 million , an increase of 0.9% ).

Acquisition sales represent sales of acquired businesses for the period up to one year subsequent to their respective acquisition dates. The acquisition sales displayed in the table above for the thirteen week period ended December 28, 2019 were attributable to the acquisition of Esterline.

Table of Contents

• Cost of Sales and Gross Profit . Cost of sales increased by $235 million , or 54.8% , to $664 million for the thirteen week period ended December 28, 2019 compared to $429 million for the thirteen week period ended December 29, 2018 . Cost of sales and the related percentage of total sales for the thirteen week period s ended December 28, 2019 and December 29, 2018 were as follows (amounts in millions):

	Thirteen Week Periods Ended — December 28, 2019	December 29, 2018		Change		% Change
Cost of sales - excluding costs below	$ 646	$ 423		$ 223		52.7	%
% of total sales	44.1 %	42.6	%

% of total sales	0.2 %	0.2	%
Acquisition integration costs	1	2		(1	)	(50.0	)%
% of total sales	0.1 %	0.2	%
Inventory acquisition accounting adjustments	—	4		(4	)	(100.0	)%
% of total sales	— %	0.4	%
Total cost of sales	$ 664	$ 429		$ 235		54.8	%
% of total sales	45.3 %	43.2	%
Gross profit	$ 801	$ 564		$ 237		42.0	%
Gross profit percentage	54.7 %	56.8	%

The increase in the dollar amount of cost of sales during the thirteen week period ended December 28, 2019 was primarily due to increased sales volume through the acquisition of Esterline in March 2019 and organically, and negative foreign currency impact. This was slightly offset by decreases in acquisition integration costs and inventory acquisition accounting costs as presented in the table above.

Gross profit as a percentage of sales decreased by 2.1 percentage points to 54.7% for the thirteen week period ended December 28, 2019 from 56.8% for the thirteen week period ended December 29, 2018 . The dollar amount of gross profit increased by $237 million , or 42.0% , for the thirteen week period ended December 28, 2019 compared to the thirteen week period in the prior year due to the following items:

• Gross profit on the sales from the acquisition of Esterline (excluding acquisition-related costs) was approximately $171 million for the thirteen week period ended December 28, 2019 , which represented gross profit of approximately 44.5% of the acquisition sales.

• Organic sales growth described above, application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers) and positive leverage on our fixed overhead costs spread over a higher production volume resulted in an increase in gross profit of approximately $78 million for the thirteen week period ended December 28, 2019 .

• Offsetting the increases in gross profit by $12 million compared to the same period in the prior fiscal year was primarily attributable to negative foreign currency impact, partially offset by decreases in inventory acquisition accounting adjustments and acquisition integration costs.

• Selling and Administrative Expenses. Selling and administrative expenses increased by $79 million to $201 million , or 13.7% of sales, for the thirteen week period ended December 28, 2019 from $122 million , or 12.3% of sales, for the thirteen week period ended December 29, 2018 . Selling and administrative expenses and the related percentage of total sales for the thirteen week period s ended December 28, 2019 and December 29, 2018 were as follows (amounts in millions):

	Thirteen Week Periods Ended — December 28, 2019	December 29, 2018	Change		% Change
Selling and administrative expenses - excluding costs below	$ 173	$ 100	$ 73		73.0	%
% of total sales	11.8 %	10.1 %
Stock compensation expense	23	16	7		43.8	%
% of total sales	1.6 %	1.6 %
Acquisition-related expenses	5	6	(1	)	(16.7	)%
% of total sales	0.3 %	0.6 %
Total selling and administrative expenses	$ 201	$ 122	$ 79		64.8	%
% of total sales	13.7 %	12.3 %

The increase in the dollar amount of selling and administrative expenses during the thirteen week period ended December 28, 2019 is primarily due to higher stock compensation expense of $7 million . The increase in stock compensation expense is primarily attributable to the stock option grants awarded to key management at the Esterline reporting units.

• Amortization of Intangible Assets. Amortization of intangible assets was $40 million for the thirteen week period ended December 28, 2019 compared to $20 million in the thirteen week period ended December 29, 2018 . The increase in amortization expense of $20 million was due to the amortization expense on the definite-lived intangible assets recorded in connection with the fiscal 2019 acquisition of Esterline.

• Refinancing Costs. Refinancing costs of $22 million were recorded for the thirteen week period ended December 28, 2019 and primarily related to the fees incurred on the redemption of the 2022 Notes that occurred in the first quarter of fiscal 2020.

• Other Income. Other income of $3 million was recorded for the thirteen week period ended December 28, 2019 and primarily related to components of net periodic pension benefit costs outside of service costs.

• Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs, original issue discount and premium and revolving credit facility fees slightly offset by interest income. Interest expense-net increased $76 million , or 44.2% , to $248 million for the thirteen week period ended December 28, 2019 from $172 million for the comparable thirteen week period last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $17.9 billion for the thirteen week period ended December 28, 2019 and approximately $13.0 billion for the thirteen week period ended December 29, 2018 . The increase in weighted average level of borrowings was primarily due to the activity in the second quarter of fiscal 2019 consisting of the issuance of $4.0 billion in 6.25% 2026 Secured Notes and the issuance of $550 million in 7.50% 2027 Notes and the activity in the first quarter of fiscal 2020 consisting of the issuance of $2.65 billion in 5.50% 2027 Notes. The increases in new debt described above were slightly offset by the redemptions of $550 million in 5.50% 2020 Notes and $1.15 billion in 6.00% 2022 Notes. The weighted average interest rate for cash interest payments on total borrowings outstanding at December 28, 2019 was 5.4%.

• Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 20.1% for the thirteen week period ended December 28, 2019 compared to 21.5% for the thirteen week period ended December 29, 2018 . The Company's lower effective tax rate for the thirteen week period ended December 28, 2019 was primarily due to a discrete benefit recognized for excess tax benefits for share-based payments during the thirteen week period ended December 28, 2019 , partially offset by an increase in the valuation allowance associated with our net interest expense limitation under IRC Section 163(j) as described in Note 10, "Income Taxes."

• Income from Discontinued Operations. Discontinued operations for the thirteen week period ended December 28, 2019 include the results of the operations of the Souriau-Sunbank Connection Technologies business ("Souriau-Sunbank"). On December 20, 2019, TransDigm completed the divestiture of Souriau-Sunbank to Eaton Corporation plc (“Eaton”) for approximately $920 million . Souriau-Sunbank was acquired by TransDigm as part of its acquisition of Esterline Technologies Corporation in March 2019. The income from discontinued operations for the thirteen week period ended December 28, 2019 is $71 million which includes $9 million for Souriau-Sunbank's operations and a gain on the sale of Souriau-Sunbank, net of tax, of $62 million . There were no discontinued operations for the thirteen week period ended December 29, 2018 .

Table of Contents

Backlog

As of December 28, 2019 , the Company estimated its sales order backlog at $3,528 million compared to an estimated sales order backlog of $2,181 million as of December 29, 2018 . The increase in backlog is due to growth from recent acquisitions, particularly the Esterline acquisition, and organic growth in the commercial aftermarket, commercial OEM and defense markets. The majority of the purchase orders outstanding as of December 28, 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 December 28, 2019 may not necessarily represent the actual amount of shipments or sales for any future period.

Foreign Operations

Although we manufacture a significant portion of our products in the United States, we manufacture 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 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 in the first quarter of fiscal 2020, interest payments will increase going forward in accordance with the terms of the related indenture. 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 to 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.

On December 20, 2019, TransDigm completed the divestiture of Souriau-Sunbank to Eaton Corporation plc (“Eaton”) for approximately $920 million . Souriau-Sunbank was acquired by TransDigm as part of its acquisition of Esterline Technologies Corporation in March 2019. Also on December 20, 2019, the Company announced that TD Group's Board of Directors authorized and declared a special cash dividend of $32.50 on each outstanding share of common stock and cash dividend equivalent payments on options granted under its stock incentive plans. The record date for the special dividend was December 30, 2019, and the payment date for the dividend was January 7, 2020. The total cash payment related to the special dividend and dividend equivalent payments on January 7, 2020 was approximately $1.9 billion, which was funded by existing cash on hand and the proceeds received from the completed Souriau-Sunbank divestiture.

We do not anticipate declaring regular quarterly or annual cash dividends on our common stock in the near future. Any declaration of special cash dividends on our common stock in the future will be at the discretion of our Board of Directors and will depend upon our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions under the senior secured credit facility and Indentures, the availability of surplus under Delaware law and other factors deemed relevant by our Board of Directors. TD Group is a holding company and conducts all of its operations through direct and indirect subsidiaries. Unless TD Group receives dividends, distributions, advances, transfers of funds or other payments from our subsidiaries, TD Group will be unable to pay any dividends on our common stock in the future. The ability of any subsidiaries to take any of the foregoing actions is limited by the terms of our senior secured credit facility and Indentures and may be limited by future debt or other agreements that we may enter into. In the future, the Company may increase its borrowings in connection with acquisitions, if cash flow from operating activities becomes insufficient to fund current operations or for other short-term cash needs or for stock repurchases or dividends. Our future leverage will also be impacted by the then current conditions of the credit markets.

Operating Activities. The Company generated $433 million of net cash from operating activities during the thirteen week period ended December 28, 2019 compared to $330 million during the thirteen week period ended December 29, 2018 . The increase is primarily attributable to the additional net operating cash inflows generated by the Esterline businesses.

The change in accounts receivable during the thirteen week period ended December 28, 2019 was a source of cash of $51 million compared to a source of cash of $45 million during the thirteen week period ended December 29, 2018 . The increase in the source of cash of $6 million is primarily attributable to an increase in sales and related timing of receipt of payment from customers.

The change in inventories during the thirteen week period ended December 28, 2019 was a use of cash of $69 million compared to a use of cash of $29 million during the thirteen week period ended December 29, 2018 . The increase in the use of cash is related to an increase in backlog resulting in additional raw material purchases for expected order fulfillments in the second fiscal quarter.

The change in accounts payable during the thirteen week period ended December 28, 2019 was a use of cash of $14 million compared to a source of cash of $3 million during the thirteen week period ended December 29, 2018 .

Investing Activities . Net cash provided by investing activities was $877 million during the thirteen week period ended December 28, 2019 , consisting of proceeds of $904 million from the divestiture of Souriau-Sunbank and partially offset by capital expenditures of $27 million .

Net cash used in investing activities was $53 million during the thirteen week period ended December 29, 2018 consisting of payments for acquisitions of $29 million , which primarily consisted of Extant's acquisition of NavCom for approximately $27 million, and capital expenditures of $24 million .

Financing Activities. Net cash provided by financing activities during the thirteen week period ended December 28, 2019 was $1,414 million . The source of cash was primarily attributable to $2,625 million in net proceeds from the completion of the 2027 5.50% Notes offering and $20 million in proceeds from stock option exercises. Sources were partially offset by the redemption of the 2022 Notes outstanding for $1,168 million and the payment of $64 million in dividend equivalent payments. In connection with the $32.50 special dividend declared on December 20, 2019, approximately $1,864 million in special dividends and dividend equivalent payments were made in the second fiscal quarter of 2020.

Net cash used in financing activities during the thirteen week period ended December 29, 2018 was $10 million . The use of cash was primarily attributable to the payment of $24 million in dividend equivalent payments partially offset by $14 million in proceeds from stock option exercises.

Description of Senior Secured Term Loans and Indentures

Senior Secured Term Loans Facility

TransDigm has $7,524 million in fully drawn term loans (the “Term Loans Facility”) and a $760 million revolving credit facility. The Term Loans Facility consists of three tranches of term loans as follows (aggregate principal amount disclosed is as of December 28, 2019 ):

Term Loans Facility	Aggregate Principal	Maturity Date	Interest Rate
Tranche E	$2,221 million	May 30, 2025	LIBO rate + 2.5%
Tranche F	$3,524 million	June 9, 2023	LIBO rate + 2.5%
Tranche G	$1,779 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 December 28, 2019 , the Company had $41.8 million in letters of credit outstanding and $718.2 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, 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 thirteen week period ended December 28, 2019 , the applicable interest rates ranged from approximately 4.2% to 4.5% 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 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.

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 December 28, 2019 .

In addition, under the Credit Agreement, if the usage of the revolving credit facility exceeds 35% 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

Table of Contents

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 December 28, 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 one 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 30, 2019, the Company amended the Securitization Facility to extend the maturity date to July 28, 2020. As of December 28, 2019 , the Company has borrowed $350 million under the Securitization Facility, which bears interest at a rate of 0.9% plus LIBOR. At December 28, 2019, the applicable interest rate was 2.6%. 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 existi ng Notes. No repurchases were made under the program during the quarter ended December 28, 2019 . As of December 28, 2019 , $650 million in repurchases are allowable under the program subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.

Off-Balance Sheet Arrangements

The Company utilizes letters of credit to back certain payment and performance obligations. Letters of credit are subject to limits based on amounts outstanding under the Company’s revolving credit facility. As of December 28, 2019, the Company had $41.8 million in letters of credit outstanding.

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 (“US 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 US 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 US 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 US GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with US 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 (for the fiscal year ended September 30, 2019). These market risks have not materially changed for the first quarter of fiscal 2020.

ITEM 4. CONTROLS AND PROCEDURES

As of December 28, 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 the 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.

Changes in Internal Control over Financial Reporting

Beginning on October 1, 2019, the Company implemented ASC 842, "Leases." The adoption of ASC 842 resulted in changes to processes and control activities related to lease accounting, including the implementation of a supporting information technology application. There have been no other changes in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended December 28, 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. 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, 2019, filed on November 19, 2019. There have been no material changes for the first quarter of fiscal 2020 to the risk factors set forth therein.
