TRANSDIGM GROUP INCORPORATED
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
THIRTEEN WEEK PERIODS ENDED JANUARY 2, 2021 AND DECEMBER 28, 2019
(UNAUDITED)
1.    DESCRIPTION OF THE BUSINESS AND IMPACT OF COVID-19 PANDEMIC
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 products. 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, batteries and chargers, engineered latching and locking devices, engineered rods, engineered connectors and elastomer sealing solutions, databus and power controls, cockpit security components and systems, specialized and advanced cockpit displays, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered and customized interior surfaces and related components, advanced sensor products, switches and relay panels, thermal protection and insulation, lighting and control technology, parachutes, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems.
Impact of COVID-19 Pandemic - Restructuring Costs
The commercial aerospace industry continues to be significantly disrupted, both domestically and internationally, by the COVID-19 pandemic resulting in ongoing business challenges. Material actions to reduce costs in response to the impact that the pandemic has had on operating results include: (1) reducing the Company's workforce to align operations with customer demand through a reduction in force or through a realignment of certain business units; (2) implementing unpaid furloughs and salary reductions; (3) delaying non-essential capital projects and (4) minimizing discretionary spending.
For the thirteen week period ended January 2, 2021, COVID-19 restructuring costs of approximately $20 million were incurred, of which $13 million was recorded in cost of sales and $7 million was recorded in selling and administrative expenses on the condensed consolidated statements of income. These costs are primarily related to the Company's actions to reduce its workforce to align with customer demand. Additionally, the Company incurred approximately $1 million in incremental costs related to the pandemic that are not expected to recur once the pandemic has subsided and are clearly separable from normal operations (e.g., additional cleaning and disinfecting of facilities by contractors above and beyond normal requirements, personal protective equipment, etc.). There were no COVID-19 restructuring costs or incremental costs incurred related to the pandemic for the thirteen week period ended December 28, 2019.
As of January 2, 2021 and September 30, 2020, the restructuring accrual associated with the costs incurred in response to the COVID-19 pandemic was approximately $27 million and $13 million, respectively. This accrual is recorded as a component of accrued and other current liabilities on the condensed consolidated balance sheets. The Company expects to incur and pay additional restructuring costs during fiscal 2021 related to the COVID-19 pandemic though at a reduced level in comparison to fiscal 2020. The Company continues to analyze its cost structure and may implement additional cost reduction measures as necessary due to the ongoing business challenges resulting from the COVID-19 pandemic.
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 Condensed Consolidated Financial Statements 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, 2020 included in TD Group’s Form 10-K filed on November 12, 2020. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). The September 30, 2020 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the thirteen week period ended January 2, 2021 are not necessarily indicative of the results to be expected for the full year.

3.    ACQUISITIONS AND DIVESTITURES
Acquisitions
Cobham Aero Connectivity – On November 24, 2020, the Company entered into a definitive agreement to acquire Cobham Aero Connectivity (“CAC”) for approximately $959 million in cash. The acquisition was substantially completed on January 5, 2021 and financed through existing cash on hand. A portion of the acquisition representing approximately 2% of the purchase price remains subject to Finnish regulatory approval and is expected to close during the second quarter of fiscal 2021. CAC operates from two primary facilities (Marlow, United Kingdom and Prescott, Arizona) and is a leading provider of highly engineered antennas and radios for the aerospace end market. The products are primarily proprietary with significant aftermarket content and have a strong presence across major defense platforms as well as select commercial applications. CAC will be included in TransDigm's Airframe segment.
The acquisition will 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 the 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.
Divestitures
Racal Acoustics – On January 29, 2021, TransDigm completed the divestiture of the Racal Acoustics business (“Racal”) to Invisio Communications AB for approximately $20 million in cash. Racal was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and is included in TransDigm's Non-aviation segment. During the first quarter of fiscal 2021, the Company determined Racal met the criteria to be classified as held for sale. Therefore, the assets and liabilities of Racal, which are not material, have been presented as held for sale in the condensed consolidated balance sheet as of January 2, 2021.
Avista – On November 17, 2020, TransDigm completed the divestiture of the Avista, Inc. business ("Avista") to Belcan, LLC ("Belcan") for approximately $8 million. Avista was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Airframe segment. During the fourth quarter of fiscal 2020, the Company determined Avista met the criteria to be classified as held for sale. Therefore, the assets and liabilities of Avista, which were not material, have been presented as held for sale in the condensed consolidated balance sheet as of September 30, 2020.
Souriau-Sunbank – On December 20, 2019, TransDigm completed the divestiture of the Souriau-Sunbank Connection Technologies business (“Souriau-Sunbank”) to Eaton Corporation plc (“Eaton”) for approximately $920 million. Souriau-Sunbank was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Non-aviation segment. Refer to Note 18, "Discontinued Operations," for additional disclosures on the Souriau-Sunbank divestiture.
4.    RECENT ACCOUNTING PRONOUNCEMENTS
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. The Company adopted ASU 2016-13 on October 1, 2020. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. Refer to Note 5, "Revenue Recognition," for additional disclosures.
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 on October 1, 2020. The adoption of this standard did not have a material impact on our condensed consolidated financial statements and disclosures.
7

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 U.S. 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. The Company is currently evaluating the impact of adopting this standard on our condensed consolidated financial statements and disclosures.
In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform." This ASU provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as the London Interbank Offered Rate ("LIBOR"). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in this ASU are effective through December 31, 2022. The Company is currently evaluating the impact of adopting this standard on our condensed consolidated financial statements and disclosures.
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, control transfers 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.
We consider the contractual consideration payable by the customer and assesses variable consideration that may affect the total transaction price. Variable consideration is included in the estimated transaction price when there is a basis to reasonably estimate the amount, including whether the estimate should be constrained in order to avoid a significant reversal of revenue in a future period. These estimates are based on historical experience, anticipated performance under the terms of the contract and our best judgment at the time.
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 condensed consolidated statements of income.
8

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. The following table summarizes our contract assets and liabilities balances (in millions):
January 2, 2021 September 30, 2020 Change

(3)Included in accrued and other current liabilities on the condensed consolidated balance sheets.
(4)Included in other non-current liabilities on the condensed consolidated balance sheets.
For the thirteen week period ended January 2, 2021, the revenue recognized that was previously included in contract liabilities was not material.
Refer to Note 13, “Segments,” for disclosures related to the disaggregation of revenue.
Allowance for Credit Losses - The Company's allowance for credit losses is the allowance for uncollectible accounts. The allowance for uncollectible accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected.
The Company’s method for developing its allowance for credit losses is based on historical write-off experience, the aging of receivables, an assessment of the creditworthiness of customers, economic conditions and other external market information. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses.
The allowance for uncollectible accounts was $41 million and $37 million as of January 2, 2021 and September 30, 2020, respectively. The increase in the allowance for uncollectible accounts in the first quarter of fiscal 2021 is primarily driven by additional collectibility risk assessed on receivables from certain customers that have been significantly adversely impacted by the COVID-19 pandemic. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

The 2029 Notes were issued pursuant to an indenture, dated January 20, 2021, among TransDigm, Inc., as issuer, TransDigm Group, TransDigm UK and the other subsidiaries of TransDigm, Inc. named therein, as guarantors.
The 2029 Notes bear interest at the rate of 4.625% per annum, which accrues from January 14, 2021 and is payable in arrears on January 15th and July 15th of each year, commencing on July 15, 2021. The 2029 Notes mature on January 15, 2029, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indenture. The Company expects to use the net proceeds from the offering of the 2029 Notes to redeem all of its outstanding 2024 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. The balance was $29.8 million at January 2, 2021 and $28.4 million at September 30, 2020.
Obligations under Finance Leases - The Company leases certain buildings and equipment under finance leases. The present value of the minimum capital lease payments, net of the current portion, represents a balance of $75.6 million at January 2, 2021 and $56.8 million at September 30, 2020. 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 January 2, 2021 and December 28, 2019, the effective income tax rate was 5.5% and 20.1%, respectively. The Company's lower effective tax rate for the thirteen week period ended January 2, 2021, which also was lower than the Federal statutory tax rate of 21%, was primarily due to the significant discrete impact of excess tax benefits associated with share-based payments.
12

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 no longer subject to U.S. federal examinations for years before fiscal 2015. 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 expects the examination in France to be completed during the current fiscal year. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later.
At January 2, 2021 and September 30, 2020, TD Group had $42.2 million and $40.9 million, respectively, in unrecognized tax benefits, the recognition of which would have an effect of approximately $37.0 million and $35.7 million on the effective tax rate at January 2, 2021 and September 30, 2020, respectively. The Company believes the tax positions that comprise the unrecognized tax benefits will be reduced by approximately $22.0 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 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 (i.e., Level 3).
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, trade accounts receivable-net and accounts payable approximated carrying value due to the short-term nature of these instruments at January 2, 2021 and September 30, 2020.
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 loss 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 loss 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 U.S. 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 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.

Based on the fair values of the interest rate swap and cap agreements determined as of January 2, 2021, 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 $13.7 million.
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 January 2, 2021, the Company had outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $123.6 million. These notional values consist of contracts for the Canadian dollar and the European euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective trade dates. There was an immaterial impact to the Company's earnings related to the effective and ineffective portion of the foreign currency forward exchange contracts designated as cash flow hedges for the thirteen week period ended January 2, 2021.
Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive loss in stockholders' deficit are reclassified into earnings when the hedged transaction settles. The maximum duration of the Company’s foreign currency cash flow hedge contracts at January 2, 2021 is 9 months. As of January 2, 2021, the Company expects to reclassify approximately $5.8 million of unrealized gain classified in other comprehensive income into earnings over the next 9 months.

13.    SEGMENTS
The Company’s businesses are organized and managed in three reporting segments: Power & Control, Airframe and Non-aviation.
The Power & Control segment includes operations that primarily develop, produce and market systems and components that predominately provide power to or control power of the aircraft utilizing electronic, fluid, power and mechanical motion control technologies. Major product offerings include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, batteries and chargers, databus and power controls, advanced sensor products, switches and relay panels, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery 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, engineered rods, engineered connectors and elastomer sealing solutions, cockpit security components and systems, specialized and advanced cockpit displays, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered and customized interior surfaces and related components, thermal protection and insulation, lighting and control technology and parachutes. 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 non-cash compensation charges incurred in connection with the Company’s stock incentive plans, restructuring costs related to the Company's cost reduction measures in response to the COVID-19 pandemic, foreign currency gains and losses, acquisition-integration costs, acquisition transaction-related expenses, and refinancing costs. COVID-19 restructuring costs represent actions taken by the Company to reduce its workforce to align with customer demand, as well as incremental costs related to the pandemic that are not expected to recur once the pandemic has subsided and are clearly separable from normal operations (e.g., additional cleaning and disinfecting of facilities by contractors above and beyond normal requirements, personal protective equipment, etc.). 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 U.S. 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 U.S. 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.

On August 8, 2019, a fire caused significant damage to the Niort, France operating facility of the Leach International Europe subsidiary, which is reported within the Company’s Power & Control segment. The facility as well as certain machinery, equipment and inventory sustained damage. The Company suspended operations at the Niort facility as a result of the fire; however, has transferred certain operations to temporary facilities until operations are fully restored at the rebuilt facility. The new facility was completed in December 2020 and certain production commenced in January 2021. The facility is expected to be fully operational in the second quarter of fiscal 2021. 
20

The Company’s insurance covers damage to the facility, equipment, inventory, and other assets, at replacement cost, as well as business interruption, and recovery-related expenses caused by the fire, subject to a $1 million deductible and certain sub-limits based on the nature of the covered item. Anticipated insurance recoveries related to losses and incremental costs incurred are recognized when receipt is probable. Anticipated insurance recoveries in excess of net book value of the damaged property and inventory will not be recorded until all contingencies relating to the claim have been resolved. As of January 2, 2021, approximately $27 million in insurance proceeds have been received. The recoveries received were previously recorded as an insurance recovery receivable (classified as a component of prepaid expenses and other on the condensed consolidated balance sheets) at the time of loss. The timing of and amount of insurance recoveries for business interruption is not known at this time.
18.    DISCONTINUED OPERATIONS
Prior Year Divestitures
On December 20, 2019, TransDigm completed the divestiture of Souriau-Sunbank to Eaton for approximately $920 million.

Overview
We believe we are a leading global designer, producer and supplier of highly engineered proprietary aerospace components with significant aftermarket content. We seek to develop highly customized products to solve specific needs for aircraft operators and manufacturers. We attempt to differentiate ourselves based on engineering, service and manufacturing capabilities. We typically choose not to compete for non-proprietary “build to print” business because it frequently offers lower margins than proprietary products. We believe that our products have strong brand names within the industry and that we have a reputation for high quality, reliability and strong customer support. Our business is well diversified due to the broad range of products that we offer to our customers. Our 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, batteries and chargers, engineered latching and locking devices, engineered rods, engineered connectors and elastomer sealing solutions, databus and power controls, cockpit security components and systems, specialized and advanced cockpit displays, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered and customized interior surfaces and related components, advanced sensor products, switches and relay panels, thermal protection and insulation, lighting and control technology, 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 first quarter of fiscal year 2021, we generated net sales of $1,108 million and net income attributable to TD Group of $50 million. EBITDA As Defined was $474 million, or 42.8% of net sales. Refer to the "Non-GAAP Financial Measures" section for certain information regarding EBITDA and EBITDA As Defined, including reconciliations of EBITDA and EBITDA As Defined to income from continuing operations and net cash provided by operating activities.
COVID-19 was first reported in December 2019, and since being declared as a pandemic by the World Health Organization in March 2020, has dramatically impacted the global health and economic environment, including millions of confirmed cases, business slowdowns or shutdowns, government challenges and market volatility. The commercial aerospace industry, in particular, has been significantly disrupted, both domestically and internationally, by the pandemic. The pandemic has resulted in governments around the world implementing stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions, business curtailments and other measures. As a result, demand for travel declined at a rapid pace beginning in the second half of fiscal 2020 and has remained significantly depressed compared to pre-pandemic levels.
Although commercial air travel demand has shown slight signs of recovery in recent months, the recovery is expected to continue to be slow and uneven depending on factors such as the trends in the number of COVID-19 infections (e.g., impact of new variants of COVID-19 surfacing), the rollout and effectiveness of the vaccine, and the eventual easing of quarantines and travel restrictions, among other factors. The exact timing and pace of the recovery is indeterminable as certain markets have reopened, some of which have since experienced a resurgence of COVID-19 cases, and in recent months new variants of COVID-19 have been identified, resulting in additional restrictions put in place by certain governments around the world.
Within the United States, our business has been designated as "essential," which has allowed us to continue to serve our customers; nonetheless, the COVID-19 pandemic has significantly disrupted our operations. The outbreak of COVID-19 has heightened the risk that a significant portion of our workforce will suffer illness or otherwise be unable to work. Furthermore, in light of enacted and any additional reductions in our workforce as a result of declines in our business caused by the COVID-19 pandemic, we cannot assure that we will be able to rehire our workforce once our business has begun to recover. Certain of our facilities have experienced temporary disruptions as a result of the COVID-19 pandemic, and we cannot predict whether our facilities will experience more significant disruptions in the future. Finally, our acquisition strategy, which is a key element of our overall business strategy, may be impacted by our efforts to maintain the Company’s cash liquidity position in response to the COVID-19 pandemic depending on the duration of the pandemic and its impact on our cash flows.
The COVID-19 pandemic has caused a significant adverse impact on our sales, net income and EBITDA as Defined and is expected to continue to do so for at least the remainder of fiscal 2021. This is under the assumption that the COVID-19 pandemic will continue to adversely impact customer demand for all market channels with commercial OEM and commercial aftermarket being the most adversely impacted due to the pandemic's impact on air travel worldwide. The defense market channel is also impacted to a significantly lesser extent due to certain supply chain disruptions as well as the "stay at home" orders, quarantines, etc. impacting the government procurement workforce. Also, government funding reprioritization such as shifting funds to efforts to combat the impact of the pandemic provides for uncertainty. The magnitude of the impact of COVID-19 remains unpredictable and we, therefore, continue to anticipate potential supply chain disruptions, employee absenteeism and short-term suspensions of manufacturing facilities, and additional health and safety costs related to the COVID-19 pandemic that could unfavorably impact our business. Longer term, because the duration of the pandemic is unclear, it is difficult to forecast a precise impact on the Company’s future results.
The Company took immediate and aggressive action to minimize the spread of COVID-19 in our workplaces and reduce costs. Since the early days of the pandemic, we have been following guidance from the World Health Organization and the U.S. Center for Disease Control to protect employees and prevent the spread of the virus within all of our facilities globally. Some of the actions implemented include: flexible work-from-home scheduling; alternate shift schedules; pre-shift temperature screenings, where allowed by law; social distancing; appropriate personal protective equipment; facility deep cleaning; and paid quarantine time for impacted employees. Material actions to reduce costs in response to the impact that the pandemic has had on operating results include: (1) reducing the Company's workforce to align operations with customer demand through a reduction in force or through a realignment of certain business units; (2) implementing unpaid furloughs and salary reductions; (3) delaying non-essential capital projects and (4) minimizing discretionary spending.
For the thirteen week period ended January 2, 2021, COVID-19 restructuring costs incurred were approximately $20 million, of which $13 million was recorded in cost of sales and $7 million was recorded in selling and administrative expenses on the condensed consolidated statements of income. These were costs related to the Company's actions to reduce its workforce to align with customer demand. Additionally, the Company incurred approximately $1 million in incremental costs related to the pandemic that are not expected to recur once the pandemic has subsided and are clearly separable from normal operations (e.g., additional cleaning and disinfecting of facilities by contractors above and beyond normal requirements, personal protective equipment, etc.). There were no COVID-19 restructuring costs or incremental costs incurred related to the pandemic for the thirteen week period ended December 28, 2019.
23

As of January 2, 2021 and September 30, 2020 the restructuring accrual associated with the costs incurred in response to the COVID-19 pandemic was approximately $27 million and $13 million, respectively. This accrual is recorded as a component of accrued and other current liabilities on the condensed consolidated balance sheets. The Company expects to incur and pay additional restructuring costs during fiscal 2021 related to the COVID-19 pandemic though at a reduced level in comparison to fiscal 2020. The Company continues to analyze its cost structure and may implement additional cost reduction measures as necessary due to the ongoing business challenges resulting from the COVID-19 pandemic.

Changes in Results of Operations
Thirteen week period ended January 2, 2021 compared with the thirteen week period ended December 28, 2019
Total Company
Net Sales. Net sales were $1,108 million for the thirteen week period ended January 2, 2021 compared to $1,465 million for the thirteen week period ended December 28, 2019. The decrease in net sales of $357 million for the thirteen week period ended January 2, 2021, compared to the thirteen week period ended December 28, 2019, is primarily related to a decreases in commercial aftermarket sales ($221 million, a decrease of 46.3%) and commercial OEM sales ($142 million, a decrease of 32.6%); partially offset by an increase in defense sales ($6 million, an increase of 1.1%). The decreases in the commercial aftermarket and commercial OEM markets are attributable to the adverse impact that the COVID-19 pandemic had on customer demand due to the pandemic's impact on air travel worldwide. The increase in defense sales are primarily driven by the OEM market.
Cost of Sales and Gross Profit. Cost of sales decreased by $97 million, or 14.6%, to $567 million for the thirteen week period ended January 2, 2021 compared to $664 million for the thirteen week period ended December 28, 2019. Cost of sales and the related percentage of total sales for the thirteen week periods ended January 2, 2021 and December 28, 2019 were as follows (amounts in millions):
Thirteen Week Periods Ended
January 2, 2021 December 28, 2019 Change % Change
Cost of sales - excluding costs below $ 545  $ 657  $ (112) (17.0) %
% of total sales 49.2  % 44.8  %
Foreign currency losses 22  14  57.1  %
% of total sales 2.0  % 1.0  %
COVID-19 pandemic restructuring costs 13  —  13  100.0  %
% of total sales 1.2  % —  %
Non-cash stock compensation expense 66.7  %
% of total sales 0.5  % 0.2  %
Acquisition integration costs —  (1) (100.0) %
% of total sales —  % 0.1  %
Loss contract amortization (18) (11) (7) (63.6) %
% of total sales (1.6) % (0.8) %
Total cost of sales $ 567  $ 664  $ (97) (14.6) %
% of total sales 51.2  % 45.3  %
Gross profit $ 541  $ 801  $ (260) (32.5) %
Gross profit percentage 48.8  % 54.7  %
The decrease in the dollar amount of cost of sales during the thirteen week period ended January 2, 2021 was primarily due to lower sales volume from decreased customer demand due to the COVID-19 pandemic and the other factors summarized above, including those factors that partially offset the decrease in cost of sales.
Gross profit as a percentage of sales decreased by 5.9 percentage points to 48.8% for the thirteen week period ended January 2, 2021 from 54.7% for the thirteen week period ended December 28, 2019. The decrease in the gross profit percentage is primarily driven by COVID-19 pandemic restructuring costs, foreign currency losses primarily due to the depreciation of the United States dollar compared to the British pound and the Euro and sales mix, specifically, lower commercial aftermarket sales as a percentage of total net sales. Also, fixed overhead costs incurred were spread over a lower production volume during the thirteen week period ended January 2, 2021 resulting in an adverse impact to gross profit.
Selling and Administrative Expenses. Selling and administrative expenses decreased by $4 million to $197 million, or 17.8% of sales, for the thirteen week period ended January 2, 2021 from $201 million, or 13.7% of sales, for the thirteen week period ended December 28, 2019. Selling and administrative expenses and the related percentage of total sales for the thirteen week periods ended January 2, 2021 and December 28, 2019 were as follows (amounts in millions):
25

Thirteen Week Periods Ended
January 2, 2021 December 28, 2019 Change % Change
Selling and administrative expenses - excluding costs below $ 139  $ 177  $ (38) (21.5) %
% of total sales 12.5  % 12.1  %
Non-cash stock compensation expense 44  23  21  91.3  %
% of total sales 4.0  % 1.6  %
COVID-19 pandemic restructuring costs —  100.0  %
% of total sales 0.6  % —  %
Bad debt expense —  100.0  %
% of total sales 0.5  % —  %
Acquisition-related expenses 100.0  %
% of total sales 0.2  % 0.1  %
Total selling and administrative expenses $ 197  $ 201  $ (4) (2.0) %
% of total sales 17.8  % 13.7  %
The decrease in selling and administrative expenses during the thirteen week period ended January 2, 2021 is primarily due to the realization of the cost mitigation measures enacted in the second half of fiscal 2020 in response to the COVID-19 pandemic, partially offset by the other factors summarized above. The material cost mitigation measures enacted to date are described in Note 1, "Description of the Business and Impact of COVID-19 Pandemic." The increase in non-cash stock compensation expense is attributable to the new stock option grants awarded in the first quarter of fiscal 2021 and the impact on the Black-Scholes fair value of the fiscal 2020 grants in connection with the change in vesting terms approved by the Compensation Committee of the Board of Directors in the first quarter of fiscal 2021. Bad debt expense is further described in Note 5, "Revenue Recognition."
Amortization of Intangible Assets. Amortization of intangible assets was $29 million for the thirteen week period ended January 2, 2021 compared to $40 million in the thirteen week period ended December 28, 2019. The decrease in amortization expense of $11 million was due to amortization expense on sales order backlog recorded in fiscal 2020 in connection with the acquisition of Esterline. Sales order backlog related to the Esterline acquisition was fully amortized by the end of fiscal 2020.
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 $19 million, or 7.7%, to $267 million for the thirteen week period ended January 2, 2021 from $248 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 $19.9 billion for the thirteen week period ended January 2, 2021 and approximately $17.9 billion for the thirteen week period ended December 28, 2019. The increase in the weighted average level of borrowings was primarily due to the activity in fiscal 2020 consisting of the issuance of $1.1 billion in 2025 Secured Notes, $400 million in 6.25% 2026 New Notes and $200 million drawn on the revolving credit facility. The weighted average interest rate for cash interest payments on total borrowings outstanding for the thirteen week period ended January 2, 2021 was 5.1%.
Refinancing Costs. There were no refinancing costs recorded for the thirteen week period ended January 2, 2021. 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.
Other Income. Other income was $5 million for the thirteen week period ended January 2, 2021 compared to $3 million for the thirteen week period ended December 28, 2019. Other income is primarily related to non-service related components of net periodic benefit costs on the Company's defined benefit pension plans and, in the first quarter of fiscal 2021, receipt of payment of a Canadian governmental subsidy.
Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 5.5% for the thirteen week period ended January 2, 2021 compared to 20.1% for the thirteen week period ended December 28, 2019. The Company's lower effective tax rate for the thirteen week period ended January 2, 2021, which also was lower than the Federal statutory tax rate of 21%, was primarily due to the significant discrete impact of excess tax benefits associated with share-based payments.
26

Income from Discontinued Operations. There were no discontinued operations for the thirteen week period ended January 2, 2021. Discontinued operations for the thirteen week period ended December 28, 2019 include the results of the operations of Souriau-Sunbank. On December 20, 2019, TransDigm completed the divestiture of Souriau-Sunbank to Eaton for approximately $920 million. Souriau-Sunbank was acquired by TransDigm as part of its acquisition of Esterline 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.
Net Income Attributable to TD Group. Net income attributable to TD Group decreased $254 million, or 84%, to $50 million for the thirteen week period ended January 2, 2021 compared to net income attributable to TD Group of $304 million for the thirteen week period ended December 28, 2019, primarily due to the adverse impact that the COVID-19 pandemic had on the Company's operations as well as the other factors referred to above.
(Loss) Earnings per Share. Basic and diluted (loss) earnings per share was $(0.42) for the thirteen week period ended January 2, 2021 and $2.07 per share for the thirteen week period ended December 28, 2019. Basic and diluted (loss) earnings per share from continuing operations was $(0.42) for the thirteen week period ended January 2, 2021. Basic and diluted earnings per share from continuing operations and discontinued operations was $0.83 and $1.24, respectively, for the thirteen week period ended December 28, 2019.
Business Segments
Segment Net Sales. Net sales by segment for the thirteen week periods ended January 2, 2021 and December 28, 2019 were as follows (amounts in millions):
Thirteen Week Periods Ended
January 2, 2021 % of Sales December 28, 2019 % of Sales Change % Change
Power & Control $ 601  54.2  % $ 752  51.3  % $ (151) (20.1) %
Airframe 464  41.9  % 674  46.0  % (210) (31.2) %
Non-aviation 43  3.9  % 39  2.7  % 10.3  %
$ 1,108  100.0  % $ 1,465  100.0  % $ (357) (24.4) %
Sales for the Power & Control segment decreased $151 million, a decrease of 20.1%, for the thirteen week period ended January 2, 2021 compared to the thirteen week period ended December 28, 2019. The sales decrease resulted primarily from decreases in commercial aftermarket sales ($88 million, a decrease of 40.0%), commercial OEM sales ($58 million, a decrease of 31.5%) and defense sales ($5 million, a decrease of 1.4%). The decreases in commercial aftermarket and commercial OEM sales are attributable to the COVID-19 pandemic.
Sales for the Airframe segment decreased $210 million, a decrease of 31.2%, for the thirteen week period ended January 2, 2021 compared to the thirteen week period ended December 28, 2019. The sales decrease resulted primarily from decreases in commercial aftermarket sales ($133 million, a decrease of 54.3%) and commercial OEM sales ($88 million, a decrease of 38.3%); partially offset by an increase in defense sales ($11 million, an increase of 5.5%). The decreases in commercial aftermarket and commercial OEM sales are attributable to the COVID-19 pandemic. The increase in defense sales are primarily driven by the OEM market.
Sales for the Non-aviation segment increased $4 million, or an increase of 10.3%, for the thirteen week period ended January 2, 2021 compared to the thirteen week period ended December 28, 2019. The sales increase resulted primarily from increases in other non-aerospace sales ($4 million, an increase of 11.7%).
EBITDA As Defined. EBITDA As Defined by segment for the thirteen week periods ended January 2, 2021 and December 28, 2019 were as follows (amounts in millions):
  Thirteen Week Periods Ended    
  January 2, 2021 % of  Segment
Sales
December 28, 2019 % of  Segment
Sales
Change % Change
Power & Control $ 304  50.6  % $ 385  51.2  % $ (81) (21.0) %

$ 496  44.8  % $ 703  48.0  % $ (207) (29.4) %
EBITDA As Defined for the Power & Control segment decreased approximately $81 million, a decrease of 21.0%, resulting from lower sales volume in the commercial aftermarket and commercial OEM markets as a result of the COVID-19 pandemic.
27

EBITDA as Defined for the Airframe segment decreased approximately $128 million, a decrease of 42.0%, resulting from lower sales volume in the commercial aftermarket and commercial OEM markets as a result of the COVID-19 pandemic.
EBITDA As Defined for the Non-aviation segment increased approximately $2 million, an increase of 15.4%, resulting from increases in other non-aerospace sales as a result of the COVID-19 pandemic.
Backlog
As of January 2, 2021, the Company estimated its sales order backlog at $3,195 million compared to $3,528 million as of December 28, 2019. The decrease in backlog is attributable to the adverse impact that the COVID-19 pandemic has had on customer demand, particularly our commercial customers, domestically and internationally. The uncertainty of the duration of the pandemic and its impact on the commercial aerospace industry is expected to continue to inhibit sales order backlog growth in the commercial OEM and commercial aftermarket channels throughout fiscal 2021.
The majority of the purchase orders outstanding as of January 2, 2021 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 January 2, 2021 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.
Sales to foreign customers are subject to numerous additional risks, including the COVID-19 pandemic, foreign currency fluctuations, the impact of foreign government regulations, political uncertainties and differences in business practices. 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 U.S. 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.
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, including the ongoing COVID-19 pandemic.
The COVID-19 pandemic has caused a significant adverse impact on our sales, net income and EBITDA as Defined during the thirteen week period ended January 2, 2021 and is expected to continue to do so for at least the remainder of fiscal 2021. This is under the assumption that the COVID-19 pandemic will continue to adversely impact customer demand for all market channels with commercial OEM and commercial aftermarket being the most adversely impacted due to the pandemic's impact on air travel worldwide. The defense market channel is also impacted to a lesser extent due to certain supply chain disruptions as well as the "stay at home" orders, quarantines, etc. impacting the government procurement workforce which has slowed production and/or orders. Also, government funding reprioritization such as shifting funds to efforts to combat the impact of the pandemic provides for uncertainty.

Although commercial air travel demand has shown slight signs of recovery in recent months, the recovery is expected to continue to be slow and uneven depending on factors such as trends in the number of COVID-19 infections (e.g., impact of new variants of COVID-19 surfacing), the rollout and effectiveness of the vaccine, and the eventual easing of quarantines and travel restrictions, among other factors. The exact timing and pace of the recovery is indeterminable as certain markets have reopened, some of which have since experienced a resurgence of COVID-19 cases, and in recent months new variants of COVID-19 have been identified, resulting in additional restrictions put in place by certain governments around the world. The magnitude of the impact of COVID-19 remains unpredictable and we, therefore, continue to anticipate potential supply chain disruptions, employee absenteeism and short-term suspensions of manufacturing facilities, and additional health and safety costs related to the COVID-19 pandemic that could unfavorably impact our business. Longer term, because the duration of the pandemic is unclear, it is difficult to forecast a precise impact on the Company’s future results.
The Company is actively managing the business to maintain cash flow, including the cost mitigation efforts described in Note 1, "Description of the Business and Impact of COVID-19 Pandemic," in the notes to the condensed consolidated financial statements included herein in response to the COVID-19 pandemic and is continuing to focus on the application of its three core value-driven operating strategies (obtaining profitable new business, continually improving its cost structure and providing highly engineered value-added products to customers).
In March 2020, the Company drew $200 million on its revolving credit facility to increase the Company's liquidity as a precautionary response to macroeconomic conditions caused by the COVID-19 pandemic. (The $200 million drawn was subsequently repaid and redrawn within the first quarter of fiscal 2021). Also, in further action to increase the Company's liquidity, the Company executed two notes offerings in April 2020 in which the proceeds received were for general Corporate purposes. On April 8, 2020, the Company entered into a purchase agreement in connection with a private offering of $1,100 million in aggregate principal amount of 8.00% Senior Secured Notes due 2025 at an issue price of 100% of the principal amount. On April 17, 2020, the Company entered into a purchase agreement in connection with a private offering of $400 million in aggregate principal amount of 6.25% Senior Secured Notes due 2026 at an issue price of 101% of the principal amount.
As of January 2, 2021, the Company has significant cash liquidity as illustrated in the table presented below (in millions):
As of January 2, 2021
Cash and cash equivalents $ 4,907 
Availability on revolving credit facility 520 
Cash liquidity (1)
$ 5,427 
(1)Excludes approximately $959 million in existing cash on hand used to acquire CAC. Refer to Note 3, "Acquisitions and Divestitures," in the notes to the condensed consolidated financial statements for further disclosure on the CAC acquisition.
Due to favorable market conditions in the high yield bond market, on January 14, 2021, the Company entered into a purchase agreement in connection with a private offering of $1,200 million of 4.625% Senior Subordinated Notes due 2029 (herein, the “2029 Notes”) at an issue price of 100% of the principal amount. The 2029 Notes were issued pursuant to an indenture, dated January 20, 2021. The Company expects to use the net proceeds from the offering of the 2029 Notes to redeem all of its outstanding 6.50% Senior Subordinated Notes due 2024, effectively resulting in a reduced interest rate and an extended maturity date of $1,200 million in senior subordinated notes.
We believe our significant cash liquidity, even after consideration of the cash on hand used to acquire CAC, will allow us to meet our anticipated funding requirements. We expect to meet our short-term cash liquidity requirements (including interest obligations and capital expenditures) through net cash from operating activities, cash on hand and, if needed, additional draws on the revolving credit facility. Long-term cash liquidity requirements consist primarily of obligations under our long-term debt agreements. There will be no maturity on any tranche of term loans or notes until August 2024.
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 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 strategic business acquisitions, pay dividends to our shareholders and make opportunistic investments in our own stock, subject to any restrictions in our existing credit agreement and market conditions in consideration of the COVID-19 pandemic.
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 $274 million of net cash from operating activities during the thirteen week period ended January 2, 2021 compared to $433 million during the thirteen week period ended December 28, 2019.
The change in accounts receivable during the thirteen week period ended January 2, 2021 was a source of cash of $86 million compared to a source of cash of $51 million during the thirteen week period ended December 28, 2019. The increase in the source of cash of $35 million is primarily attributable to timing of cash collections on prior quarter sales. The Company also continues to actively manage its accounts receivable, the related agings and collection efforts in response to the COVID-19 pandemic.
The change in inventories during the thirteen week period ended January 2, 2021 was a source of cash of $1 million compared to a use of cash of $69 million during the thirteen week period ended December 28, 2019. The increase in the source of cash is primarily driven by lower inventory levels and decreased purchasing due to reduced demand as a result of the COVID-19 pandemic.
The change in accounts payable during the thirteen week period ended January 2, 2021 was a use of cash of $20 million compared to a use of cash of $14 million during the thirteen week period ended December 28, 2019. The increase in the use of cash is primarily driven by a corresponding decline in accounts payable as inventory and other purchases have slowed as a result of the COVID-19 pandemic.
Investing Activities. Net cash used by investing activities was $29 million during the thirteen week period ended January 2, 2021, consisting primarily of capital expenditures of $31 million. This was partially offset by proceeds of $8 million from the completion of the divestiture of Avista, Inc.
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 completion of the divestiture of Souriau-Sunbank. This was partially offset by capital expenditures of $27 million.
Financing Activities. Net cash used by financing activities during the thirteen week period ended January 2, 2021 was $60 million. The use of cash was primarily attributable to dividend equivalent payments of $73 million and repayment on term loans of $19 million. This was partially offset by proceeds from stock option exercises of $32 million.
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. This was partially offset by the redemption of the 2022 Notes outstanding for $1,168 million and the payment of $64 million in dividend equivalent payments.
Contractual Obligations
We have future obligations under various contracts relating to debt and interest payments, finance and operating leases, pension and post-retirement benefit plans and purchase obligations. There were no material changes during the thirteen week period ended January 2, 2021 to these obligations as reported in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020.
