The Company intends to use the net proceeds from both secured notes offerings to fund the purchase price of the Esterline acquisition. Refer to Note 16, "Subsequent Events," for further information.
During the twenty-sixthirteen week period ended March 31,December 29, 2018, Extant Aerospace ("Extant"), a wholly owned subsidiary of the Company, completed the acquisition of substantially all of the Kirkhill elastomers businessassets and technical data rights of NavCom Defense Electronics ("Kirkhill"NavCom") from Esterline Technologies.. During the fiscal year ended September 30, 2017,2018, the Company completed the acquisitions of three separate aerospace product lines (collectively,Skandia Inc. ("Skandia"), Extant, and the "Third Quarter 2017 Acquisitions"Kirkhill elastomers business ("Kirkhill"). The Company accounted for the acquisitions using the acquisition method and included the results of operations of the acquisitions in its condensed consolidated financial statements from the effective date of each acquisition. As of March 31,December 29, 2018, the one-year measurement period is open for KirkhillNavCom, Skandia, Extant and the Third Quarter 2017 Acquisitions;Kirkhill; therefore, the assets acquired and liabilities assumed related to these acquisitions are subject to adjustment until the end of their respective one-year measurement

periods. The Company is in the process of obtaining a third-party valuation of certain intangible assets and tangible assets of NavCom and Skandia. Pro forma net sales and results of operations for the acquisitions had they occurred at the beginning of the applicable twenty-sixthirteen week period ended March 31,December 29, 2018 or April 1,December 30, 2017 are not material and, accordingly, are not provided.
The acquisitions strengthen and expand the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies (obtaining profitable new business, improving our cost structure, and providing highly engineered value-added products to customers). 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.
NavCom – 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. The Company expects that approximately $11 million goodwill recognized for the acquisition will be deductible for tax purposes over 15 years.
Skandia – On July 13, 2018, the Company acquired all of the outstanding stock of Skandia for a total purchase price of approximately $84.3 million, which includes a $0.2 million working capital settlement paid in the fourth quarter of fiscal 2018. Skandia provides highly engineered seating foam, foam fabrication, flammability testing and acoustic solutions for the business jet market. Skandia is included as a product line within an existing reporting unit in TransDigm's Airframe segment. The Company expects that no goodwill recognized for the acquisition will be deductible for tax purposes.
Extant – On April 24, 2018, the Company acquired all of the outstanding stock of Extant for a total purchase price of approximately $533.4 million in cash, which is net of a $0.2 million working capital settlement received in the third quarter of fiscal 2018. Extant provides a broad range of proprietary aftermarket products and repair and overhaul services to the aerospace and defense end markets. Extant is included in TransDigm's Power and Control segment.
Prior to the Company's acquisition of Extant, Extant was owned by an equity fund sponsored by Warburg Pincus LLC. Michael Graff, a director of TransDigm, is a managing director of Warburg Pincus LLC and was chairman of the board of Extant.  Robert Henderson, Vice Chairman of TransDigm, was also on the board of Extant and owned less than 2% of Extant on a fully diluted basis. In addition, Mr. Graff, Mr. W. Nicholas Howley, TransDigm's Executive Chairman, and Messrs. Douglas Peacock and David Barr, directors of TransDigm, each had minority interests of less than 1% in the Warburg Pincus LLC fund that owned Extant.
The total purchase price of Extant was allocated to the underlying assets acquired and liabilities assumed based upon management’s estimated fair values at the date of acquisition. To the extent the purchase price exceeded the estimated fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill. The following table summarizes the purchase price allocation of the estimated fair values of the assets acquired and liabilities assumed at the transaction date (in thousands).
Assets acquired: 
Current assets, excluding cash acquired$56,031
Property, plant, and equipment4,096

Other noncurrent liabilities25,028
Total liabilities assumed34,904
Net assets acquired$533,381
The Company expects that approximately $44 million of the $105 million intangibles recognized for the acquisition will be deductible for tax purposes over 15 years. Of the $403 million of goodwill recognized for the acquisition, none will be deductible for tax purposes.

Kirkhill – On March 15, 2018, the Company acquired the assets and certain liabilities of the Kirkhill elastomers business from Esterline Technologies for a total purchase price of approximately $50$49.3 million, which is net of a $0.6 million working capital settlement received in cash subject to purchase price adjustments.the third quarter of fiscal 2018. Kirkhill's products are primarily proprietary, sole source with significant aftermarket content and used in a broad variety of most major commercial transport and military platforms. Kirkhill is also well represented on newer commercial platforms such as Boeing’s 787, 777X and 737MAX; Airbus’s A320NEO and A350; as well as the military JSF. Kirkhill is included in TransDigm's Airframe segment. The Company expects that no goodwill recognized for the acquisition will be deductible for tax purposes.
Third Quarter 2017 Acquisitions The Third Quarter 2017 Acquisitions were acquired for an aggregate purchase priceKirkhill acquisition includes loss contract reserves recorded at a fair value of approximately $106.7$37.5 million in cash, which includes working capital settlements totaling $1.0at December 29, 2018 and $39.2 million paidat September 30, 2018. As of December 29, 2018 and September 30, 2018, $7.3 million and $9.0 million is classified as a component of accrued liabilities and $30.2 million at both December 29, 2018 and September 30, 2018 is classified as a component of other non-current liabilities in the third and fourth quarters of 2017 and an earn-out of $0.4 million paid in the second quarter of 2018. All three product lines consist primarily of proprietary, sole source products with significant aftermarket content. The products include highly engineered aerospace controls, quick disconnect couplings, and communication electronics. Each product line acquired wascondensed consolidated into an existing TransDigm reporting unit within TransDigm's Power & Control segment.balance sheets. The Company expectsis committed under certain existing Kirkhill agreements to supply products to our customers at selling prices that approximately $66 millionare not sufficient to cover the costs to produce such product. These agreements were existing at the time of goodwill recognized for the acquisitions will be deductible for tax purposes over 15 yearsacquisition. The value of this reserve is analyzed and approximately $9 million of goodwill recognized for the acquisitions will not be deductible for tax purposes.adjusted at each reporting period.
Schroth – On February 22, 2017, the Company acquired all of the outstanding stock of Schroth Safety Products GmbH and certain aviation and defense assets and liabilities from subsidiaries of Takata Corporation (collectively, "Schroth"), for a total purchase price of approximately $89.7 million, which consisted primarily of $79.7 million paid in cash during fiscal 2017 and an approximately $9.0 million indemnity holdback, of which $8.5 million was paid in April 2018 and $0.5 million remains a reserve as of December 29, 2018.
In connection with the settlement of a Department of Justice investigation into the competitive effects of the acquisition, during the fourth quarter of 2017, the Company committed to dispose of the Schroth business. Therefore, Schroth was classified as held-for-sale beginning in the fourth quarter of 2017. The2017 and the results of operations of Schroth arewere reflected as discontinued operations in the accompanying condensed consolidated financial statements.

4.    RECENT ACCOUNTING PRONOUNCEMENTS
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, which created a new topic in the Accounting Standards Codification (“ASC”) 606, “Revenue Fromfrom Contracts With Customers.with Customers. In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishesrequires an entity to recognize revenue in a new control-based revenue recognition model.manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

The Company expects to useadopted this standard in the first quarter of 2019 using the modified retrospective method. The Company is continuing to evaluate theadoption of this standard did not have a material impact of the standard. For each reporting unit, we have evaluated a representative sample of contracts and other agreements with our customers and evaluated the provisions contained within these contracts and agreements in consideration of the five step model specified within ASC 606. We are in the process of documenting the impact of the standard on our current accounting policies and practices in orderconsolidated results of operations, financial position or cash flows. Refer to identify material differences, if any, that would result from applying the new requirementsNote 5, "Revenue Recognition," for additional disclosures relating to our revenue contracts. We continue to make progress on our assessment of ASC 606 and are also in the process of evaluating the impact, if any, on changes to our business processes, systems, and controls to support recognition and disclosure requirements under ASC 606.
In February 2016, the FASB issued ASU 2016-02, “Leases (ASC 842),” which will require that a lessee recognize assets and liabilities on the balance sheet for all leases with a lease term of more than twelve months, with the result being the recognition of a right of use asset and a lease liability.  Additionally, in July 2018, the FASB issued ASU 2018-10, "Codification Improvements to ASC 842, Leases" which provides narrow amendments to clarify how to apply certain aspects of the new leases standard. The new leases standard guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2019, with early adoption permitted.  The Company is currently evaluating the impact of adopting this standard on itsour consolidated financial statements and disclosures.

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

In AugustOctober 2016, the FASB issued ASU 2016-15, "Statement2016-16, “Intra-Entity Transfers of Cash Flows—ClassificationAssets Other Than Inventory” (ASU 2016-16).

In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. Employers will have to disclose the line(s)lines used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement.Thestatement.

The adoption of this standard isdid not expected to have a material impact on our consolidated financial statements.
In May 2017, the FASB issued ASU 2017-09, "Compensation—Stock Compensation (ASC 718): Scope of Modification Accounting," which provides clarity on which changes to the terms or conditions of share-based payment awards require an entity to apply the modification accounting provisions required in ASC 718. The standard is effective for all entities for annual periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (ASC 815): Targeted Improvements to Accounting for Hedging Activities,” which amends the FASB’s hedge accounting model to enable entities to better portray their risk management activities in financial statements. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair valuefirst quarter of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. ASU 2017-12 is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2018, with early adoption permitted. As early adoption is permissible, the Company adopted the pronouncement beginning October 1, 2017. Changes were applied prospectively in accordance with the standard and prior periods were not adjusted.fiscal 2019. The adoption of this standard did not have a material impact on our consolidated financial statements and disclosures.statements.
In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic(ASC 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which gives entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (the "Act") into retained earnings. The guidance allows entities to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the Act's new federal corporate income tax rate. The guidance also allows entities to elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the change in the federal tax rate (e.g., state taxes, changing from a worldwide tax system to a territorial system). Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. The standard is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within the fiscal year. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Entities have the option to apply the guidance retrospectively or in the period of adoption. The adoption of this standard is not expected to have a material impact on our consolidated financial statements.
In March 2018, the FASB issued ASU 2018-05, “Income Taxes (Topic(ASC 740), Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118.” The ASU adds various SEC paragraphs pursuant to the issuance of the December 2017 SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which was effective immediately. The SEC issued SAB 118 to address concerns about reporting entities’

ability to timely comply with the accounting requirements to recognize all of the effects of the Tax Cuts and Jobs Act in

the period of enactment. SAB 118 allowsallowed disclosure that timely determination of some or all of the income tax effects from the Tax Cuts and Jobs Act arewere incomplete by the due date of the financial statements and if possible to provide a reasonable estimate.

Such finalization did not result in a material impact to the provisional basis. Our accounting for certain income tax effects is incomplete, but we have determined reasonable estimates for those effects and havepreviously recorded provisional amounts in our condensed consolidated financial statements. Refer to Note 9,10, "Income Taxes," for further information.
In accordance with SEC Final Rule Release No. 33-10532, we have adopted Rule 3-04 of Regulation S-X during the first quarter of fiscal 2019 and have disclosed changes in the Consolidated Condensed Statements of Stockholders' Deficit for all periods presented.
5.    REVENUE RECOGNITION
The Company adopted ASC 606, “Revenue from Contracts with Customers,” beginning October 1, 2018 using the modified retrospective method.
The new standard primarily impacted the Company's timing of revenue recognition for certain contracts and subcontracts with the U.S. government that contain termination for convenience clauses and resulted in an increase to retained earnings of $3.3 million. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.
The cumulative effect of the changes made to our condensed consolidated balance sheet as of October 1, 2018 for the adoption of ASC 606 were as follows (in thousands):

The Company does not expect the impact of the adoption of ASC 606 to be material on an ongoing basis.
The impact of the adoption of ASC 606 on the condensed consolidated statement of income and condensed consolidated balance sheet was not material for the thirteen week period ended December 29, 2018.
Accounting Policy —Revenue is recognized from the sale of products when control transfers to the customer, which is demonstrated by our right to payment, a transfer of title, a transfer of the risk and rewards of ownership, or the customer acceptance, but most frequently upon shipment where the customer obtains physical possession of the good.
The majority of the Company's revenue is recorded at a point in time.
In some contracts, the Company found that under ASC 606 control transferred to the customer over time, primarily in contracts where the customer is required to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit relative to the work performed for products that were customized for the customer. Upon adoption of ASC 606, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use.  Prior to the adoption date, revenue related to these agreements was recognized when the goods were shipped; as a result of the adoption of ASC 606, a portion of our revenue may be earned in periods earlier than it would have been in prior years. The cumulative adjustment to retained earnings upon adoption, which is presented in the table above, represents those earnings that would have been recognized in the previous year had ASC 606 been in effect during that time.
Based on our production cycle, it is generally expected that goods related to the revenue represented in that adjustment will be shipped and billed within the current year. For revenue recognized over time, we estimate the amount of revenue attributable to a contract earned at a given point during the production cycle based on certain costs, such as materials and labor incurred to date, plus the expected profit, which is a cost-to-cost input method.
The Company’s payment terms vary by the type and location of the customer and the products or services offered. The Company does not offer any payment terms that would meet the requirements for consideration as a significant financing component under ASC 606.

Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in the consolidated statements of income, and are not considered a performance obligation to our customers.
The Company pays sales commissions that relate to contracts for products or services that are satisfied at a point in time or over a period of one year or less and so are recorded per the practical expedient expensed as incurred. These costs are reported as a component of selling and administrative expenses in the unaudited condensed consolidated statement of operations.
We offer assurance type warranties on our products as well as separately sold warranty contracts. Revenue related to warranty contracts that are sold separately is recognized over the life of the warranty term. 
Variable consideration is estimated at the expected value (sum of the probability of weighted amounts) or most likely amount, whichever method is found to be most appropriate to estimate the consideration to which the Company will be entitled, and only to the extent it is probable that a subsequent change in estimate will not result in a significant revenue reversal when estimating the amount of revenue to recognize.  Variable consideration is treated as a change to the sales transaction price and based largely on an assessment of all information (i.e., historical, current and forecasted) that is reasonably available to the Company. Variable consideration is estimated at contract inception and updated at the end of each reporting period as additional information becomes available.
Contract Assets and Liabilities - Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing or reimbursable costs related to a specific contract. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. The following table summarizes our contract assets and liabilities balances (in thousands):

Amendment No.4 to the Second Amended and Restated Credit Agreement - On November 30, 2017, the Company entered into Amendment No. 4 to the Second Amended and Restated Credit Agreement. Pursuant to Amendment No. 4, TransDigm, among other things, converted approximately $798 million of existing tranche D term loans into additional tranche F term loans and decreased the margin applicable to the existing tranche E term loans and tranche F term loans to LIBO rate plus 2.75% per annum. The terms and conditions (other than maturity date) that apply to the tranche F term loans, including pricing, are substantially the same as the terms and conditions that apply to the tranche D term loans immediately prior to Amendment No. 4.
The Company capitalized $2.9 million and expensed $0.7 million of refinancing costs representing debt issuance costs associated with Amendment No. 4 during the twenty-six week period ended March 31, 2018. Additionally, the Company wrote off $0.5 million in unamortized debt issuance costs related to the tranche D term loans that were converted to tranche F term loans and wrote off $0.2 million in unamortized debt issuance costs related to the tranche F terms loans.
Refinancing Facility Agreement to the Second Amended and Restated Credit Agreement -On February 22, 2018, the Company entered into a refinancing facility agreement. TransDigm, among other things, incurred new tranche G term loans in an aggregate principal amount equal to $1,809 million and repaid in full all of the existing tranche G term loans outstanding under the Second and Amended Restated Credit Agreement immediately prior to the refinancing facility agreement. The refinancing facility agreement also decreased the margin applicable to the tranche G term loans to LIBO rate plus 2.5% per annum. The terms and conditions that apply to the tranche G term loans, including pricing, are substantially the same as the terms and conditions that apply to the tranche G term loans immediately prior to the refinancing facility agreement.

The Company capitalized $0.5 million and expensed $0.2 million of refinancing costs representing debt issuance costs associated with the refinancing facility agreement during the twenty-six week period ended March 31, 2018. Additionally, the Company wrote off $0.2 million in unamortized debt issuance costs related to the tranche G terms loans.
9.10.    INCOME TAXES
The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign-sourced earnings. The rate change is administratively effective at the beginning of our fiscal year (October 1, 2017), using a blended rate for the annual period. As a result, the blended statutory tax rate for the year is 24.5%. At March 31, 2018, we had not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. We have recognized a provisional benefit amount of $170.2 million related to the remeasurement of our deferred tax balance for the twenty-six week period ended March 31, 2018. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. In addition, we have recognized a provisional expense amount of $23.1 million for our one-time transition tax liability for the twenty-six week period ended March 31, 2018. The one-time transition tax is based on our total post-1986 earnings and profits ("E&P") that we previously deferred from U.S. income taxes and is based in part on the amount of those earnings held in cash and other specified assets. However, we continue to refine the calculation of the total post-1986 E&P for our foreign subsidiaries. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from US federal taxation and finalize the amounts held in cash or other specified assets. As a result of the Act, we recognized a net provisional benefit amount of $147.1 million as a discrete tax benefit, which is included as a component of income tax expense from continuing operations for the twenty-six week period ended March 31, 2018.
At the end of each reporting period, TD Group makes an estimate of its annual effective income tax rate. The estimate used in the year-to-date period may change in subsequent periods. During the thirteen week periods ended March 31,December 29, 2018 and April 1,December 30, 2017, the effective income tax rate was 18.3%21.5% and 27.7%, respectively. During the twenty-six week periods ended March 31, 2018 and April 1, 2017, the effective income tax rate was (17.3)(63.4)% and 22.5%, respectively. The Company's lowerhigher effective tax rate for the thirteen week period ended March 31,December 29, 2018 was primarily due to the reductiondiscrete benefit recognized in the U.S. federal corporate statutory ratethirteen week period ended December 30, 2017 related to the enactmentremeasurement of deferred tax balances resulting from the Act.provisions of The Tax Cuts and Jobs Act enacted on December 22, 2017 (the "Act"). The Company’s lower effective tax rate for the twenty-six week period ended March 31,December 29, 2018 was higher than the Federal statutory rate of 21% primarily resulting from our net interest expense limitation under IRC Section 163(j) offset by the benefit associated with the deduction for foreign-derived intangible income (FDII) and excess tax benefits for share-based payments. The Company’s effective tax rate for the period ended December 30, 2017 was less than the Federal statutory tax rate primarily due to the reduction in the U.S. federal corporate tax rate as well as discrete adjustmentsadjustment related to the enactment of the Act described above. The Company’sFDII was introduced, and interest deductibility under IRC Section 163(j) was modified by the Act and were both effective tax rate for TD Group beginning the thirteen and twenty-six week periodsperiod ended March 31, 2018 was lower than the Federal statutory tax rate primarily due to enactment of the Act described above. The Company’s effective tax rate for the thirteen and twenty-six periods ended April 1, 2017 was lower than the Federal statutory tax rate primarily due to excess tax benefits from share based payments, the domestic manufacturing deduction and foreign earnings taxed at rates lower than the U.S. statutory rate.December 29, 2018.
The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions as well as foreign jurisdictions located in Belgium, Canada, China, France, Germany, Hong Kong, Hungary, Japan, Malaysia, Mexico, Norway, Singapore, Sri Lanka, Sweden and the United Kingdom. The Company is no longer subject to U.S. federal examinations for years before fiscal 2014. The Company is currently under U.S. federal examination for fiscal 2014. In addition, the Company is subject to state income tax examinations for fiscal years 20092011 and later.
At March 31,December 29, 2018 and September 30, 2017,2018, TD Group had $8.8$14.0 million and $8.7$14.1 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $8.7$13.0 million and $13.1 million on the effective tax rate at March 31,December 29, 2018 and September 30, 2017,2018, respectively. The Company believes the tax positions that comprise the unrecognized tax benefits will be reduced by approximately $0.6$1.4 million over the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.
The Act reduced the U.S. federal corporate tax rate from 35% to 21% and required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries. The Company recorded provisional tax benefits of $176.4 million related to the remeasurement of our net U.S. deferred tax liabilities to reflect the reduction in the corporate tax rate. The one-time transition tax is based on our total post-1986 earnings and profits (E&P), the tax on which the Company previously deferred from US income taxes under US tax law. The Company recorded a provisional amount for our one-time transition tax liability for each of our foreign subsidiaries resulting in an aggregate transition tax liability of $30.0 million at September 30, 2018.
Upon further analysis of the Act and notices and regulations issued and proposed by the U.S. Department of the Treasury and the Internal Revenue Service, the Company finalized its calculations for the deferred remeasurement and the transition tax liability during the thirteen week period ended December 29, 2018. Such finalization did not have a material impact on the Company’s consolidated financial statements. As a result, no adjustment to the provisional tax benefit of $176.4 million for deferred remeasurement or the $30.0 million for transition tax was recorded for the thirteen week period ended

December 29, 2018. The Company has elected to pay the transition tax over an eight-year period as provided for in the Act.
10.11.    FAIR VALUE MEASUREMENTS
The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following summarizes the carrying amounts and fair values of financial instruments (in thousands):

The carrying amount of the debt instrument is presented net of the debt issuance costs.costs, premium and discount. Refer to Note 8,9, "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.

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 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 book value due to the short-term nature of these instruments at March 31,December 29, 2018 and September 30, 2017.2018.
11.12.    DERIVATIVES AND HEDGING ACTIVITIES
The Company is exposed to, among other things, the impact of changes in interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. 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.
Interest rate swap and cap agreements are used to manage interest rate risk associated with floating-rate borrowings under our credit facility. The interest rate swap and cap agreements utilized by the Company effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating-rate debt to a fixed rate basis through the expiration date of the interest rate swap and cap agreements, thereby reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the term of the agreements without an exchange of the underlying principal amount. These derivative instruments qualify as effective cash flow hedges under GAAP. For these cash flow hedges, the effective portion of the gain or loss from the financial instruments was initially reported as a component of accumulated other comprehensive loss(loss) income in stockholders’ deficit and subsequently reclassified into earnings in the same line as the hedged item in the same period or periods during which the hedged item affected earnings. As the interest rate swap and cap agreements are used to manage interest rate risk, any gains or losses from the derivative instruments that are reclassified into earnings are recognized in interest expense - net in the condensed consolidated statements of income.

All interest rate swap and cap agreements are recognized in our condensed consolidated balance sheets at fair value. 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 long-termnon-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.

Effective September 30, 2016, the Company redesignated the interest rate cap agreements related to the $400 million and the $750 million aggregate notional amount with cap rates of 2.0% and 2.5%, respectively, based on the expected probable cash flows associated with the 2016 term loans and 2015 term loans in consideration of the Company’s ability to select one-month, two-month, three-month, or six-month LIBO rate set forth in the Second Amended and Restated Credit Agreement.  Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss(loss) income in stockholder’s deficit amortized into interest expense was $2.0$1.1 million and $1.9$1.0 million for the twenty-sixthirteen week periods ended March 31,December 29, 2018 and April 1,December 30, 2017, respectively. The accumulated other comprehensive loss to be reclassified into interest expense over the remaining term of the cap agreements is $8.9$9.9 million with a related tax benefit of $2.4$2.3 million as of March 31,December 29, 2018.
Effective December 30, 2017, the Company redesignated the existing interest rate swap agreements related to the $750 million, $500 million, $1,000 million and $750 million aggregate notional amounts with swap rates of 5.25%5.0%, 4.65%4.4%, 4.55%4.3% and 5.55%5.3%, respectively, based on the expected probable cash flows associated with the tranche Fcertain term loans in consideration of the Company’s removal of the LIBO rate floor on the tranche Fcertain term loans as set forth in Amendment No. 4 to the Second Amended and Restated Credit Agreement.  Accordingly, the amount recorded as a component of accumulated other comprehensive loss(loss) income in stockholders’ deficit related to these redesignated interest rate swap hedges will be amortized into earnings based on the original maturity date of the related interest rate swap agreements. Accordingly, amountsAmounts previously recorded as a component of accumulated other comprehensive loss(loss) income in stockholder’s deficit amortized into interest expense was $0.3 million for the twenty-sixthirteen week period ended March 31,December 29, 2018. The accumulated other comprehensive gainincome to be reclassified into interest expenseincome over the remaining term of the swapswaps agreements is immaterial.$0.9 million with a related tax expense of $0.2 million as of December 29, 2018.

12.13.    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, databus and power controls, high performance hoists, winches and lifting devices and cargo loading and handling systems. Primary customers of this segment are engine and power system and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.
The Airframe segment includes operations that primarily develop, produce and market systems and components that are used in non-power airframe applications utilizing airframe and cabin structure technologies. Major product offerings include engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, cockpit security components and systems, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes and cargo delivery systems. Primary customers of this segment are airframe manufacturers and cabin system suppliers and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.
The Non-aviation segment includes operations that primarily develop, produce and market products for non-aviation markets. Major product offerings include seat belts and safety restraints for ground transportation applications, mechanical/electro-mechanical actuators and controls for space applications, hydraulic/electromechanical actuators and fuel valves for land based gas turbines, and refueling systems for heavy equipment used in mining, construction and other industries and turbine controls for the energy and oil and gas markets. Primary customers of this segment are off-road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers, manufacturers of heavy equipment used in mining, construction and other industries and turbine original equipment manufacturers, gas pipeline builders and electric utilities.

The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items recorded as corporate expenses including refinancing costs, acquisition-related costs, transaction-related costs, foreign currency gains and losses, and non-cash compensation charges incurred in connection with the Company’s stock option plans. Acquisition-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction related costs comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments.
EBITDA As Defined is not a measurement of financial performance under GAAP. Although the Company uses EBITDA As Defined to assess the performance of its business and for various other purposes, the use of this non-GAAP financial measure as an analytical tool has limitations, and it should not be considered in isolation or as a substitute for analysis of the Company’s results of operations as reported in accordance with GAAP.
The Company’s segments are reported on the same basis used internally for evaluating performance and for allocating resources. The accounting policies for each segment are the same as those described in the summary of significant accounting policies in the Company’s consolidated financial statements. Intersegment sales and transfers are recorded at values based on market prices, which creates intercompany profit on intersegment sales or transfers that is eliminated in consolidation. Intersegment sales were insignificant for the periods presented below. Certain corporate-level expenses are allocated to the operating segments.
Effective October 1, 2017, the Company made an organizational realignment of certain businesses comprising the Power & Control, Airframe and the Non-Aviation segments. Operating results for the thirteen and twenty-six week periods ended April 1, 2017 and total assets as of September 30, 2017 were reclassified to conform to the presentation for the thirteen and twenty-six week periods ended March 31, 2018.

14.    DISCONTINUED OPERATIONS
In connection with the settlement of a Department of Justice investigation into the competitive effects of the acquisition, during the fourth quarter of 2017, the Company committed to dispose of the Schroth business.  Therefore, Schroth was classified as held-for-sale in the fourth quarter of 2017. The results of operations of Schroth are reflected as discontinued operations in the accompanying consolidated financial statements for all periods presented. On January 26, 2018, the Company completed the sale of Schroth in a management buyout to a private equity fund and certain members of Schroth management for approximately $61.4 million, subject to a working capital adjustment. The Company previously acquired Schroth in February 2017 (refer to Note 3, “Acquisitions and Divestitures”).

The loss from discontinued operations was $5.6 million and $2.8 million in the condensed consolidated statements of income for the thirteen and twenty-six week periods ended March 31, 2018. The loss from discontinued operations was $0.2 million in the condensed consolidated statements of income for the thirteen and twenty-six week periods ended April 1, 2017. Previously, in the fourth quarter of 2017, we recorded a $32.0 million impairment charge to write down the Schroth assets to fair value. The impairment charge was based on an internal assessment of the recovery of Schroth’s assets. The following is the summarized operating results for Schroth for the thirteen and twenty-six week periods ended March 31, 2018 and April 1, 2017 (in thousands):

The notes in the first secured notes offering will be issued at a price of 100% of their principal amount and the notes in the second secured notes offering will be issued at a price of 101% of their principal amount. The Notes will be guaranteed, with certain exceptions, by TransDigm Group, TransDigm UK and all of TransDigm Inc.’s existing and future U.S. subsidiaries on a senior secured basis.

This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including, in particular, the statements about the Company’s plans, strategies and prospects under this section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” When used in this Quarterly Report on Form 10-Q, the words “believe,” “may,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate” or “continue” and other words and terms of similar meaning are intended to identify forward-looking statements.

The net increase in the dollar amount of cost of sales during the twenty-six week period ended March 31, 2018 was primarily due to increased volume associated with the sales from acquisitions and organic commercial aftermarket sales growth.

Gross profit as a percentage of sales increased by 1.2 percentage points to 56.7% for the twenty-six week period ended March 31, 2018 from 55.5% for the twenty-six week period ended April 1, 2017. The dollar amount of gross profit increased by $77.0 million, or 8.2%, for the twenty-six week period ended March 31, 2018 compared to the comparable twenty-six week period in the prior year due to the following items:
Gross profit on the sales from the acquisitions indicated above (excluding acquisition-related costs) was approximately $10.3 million for the twenty-six week period ended March 31, 2018, which represented gross profit of approximately 59.0% of the acquisition sales.
Organic sales growth described above, application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers) and positive leverage on our fixed overhead costs spread over a higher production volume resulted in a net increase in gross profit of approximately $49.5 million for the twenty-six week period ended March 31, 2018.

Also contributing to the increase in gross profit were lower inventory purchase accounting adjustments of $19.4 million slightly offset by increases in acquisition integration costs of $2.0 million and stock compensation expense of $0.2 million charged to cost of sales for the twenty-six week period ended March 31, 2018.
Selling and Administrative Expenses. Selling and administrative expenses increased by $11.5 million to $214.1 million, or 12.0% of sales, for the twenty-six week period ended March 31, 2018 from $202.6 million, or 12.0% of sales, for the twenty-six week period ended April 1, 2017.

The increase in the dollar amount of selling and administrative expenses during the twenty-six week period ended March 31, 2018 is primarily due to higher selling and administration expenses related to recent acquisitions.
Amortization of Intangible Assets. Amortization of intangible assets was $34.6 million for the twenty-six week period ended March 31, 2018 compared to $47.6 million in the twenty-six week period ended April 1, 2017. The decrease in amortization expense of $13.0 million was primarily due to the order backlog recorded in connection with the 2016 acquisitions becoming fully amortized in fiscal 2017. This was slightly offset by amortization expense on the definite-lived intangible assets (i.e., technology and order backlog) recorded in connection with the Third Quarter 2017 acquisitions.
Refinancing Costs. Refinancing costs of $1.8 million were recorded for the twenty-six week period ended March 31, 2018, which related to the debt refinancing activity described in Note 8, "Debt." Refinancing costs of $35.6 million were recorded for the twenty-six week period ended April 1, 2017 representing debt issuance costs expensed in connection with the debt financing activity during the first and second quarter of the previous year, which primarily consisted of $28.8 million in premium paid on the redemption of the 2021 Notes and the write-off of $3.1 million in unamortized debt issuance costs, along with $3.3 million of debt issuance costs related to an additional issuance of our existing 2025 Notes.
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 $28.4 million, or 9.6%, to $322.2 million for the twenty-six week period ended March 31, 2018 from $293.8 million for the comparable twenty-six 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 $11,864 million for the twenty-six week period ended March 31, 2018 and approximately $11,045 million for the twenty-six week period ended April 1, 2017. The increase in weighted average level of borrowings was primarily due to the additional 2025 Notes offering of $300 million in the end of the second fiscal quarter of 2017, the additional $100 million drawn on the trade receivable securitization facility in the fourth quarter of fiscal 2017, and the additional net debt financing of $575 million in the fourth quarter of fiscal 2017. The weighted average interest rate for cash interest payments on total borrowings outstanding at March 31, 2018 was 5.2%.
Income Taxes. Income tax expense as a percentage of income before income taxes was approximately (17.3)% for the twenty-six week period ended March 31, 2018 compared to 22.5% for the twenty-six week period ended April 1, 2017. The Tax Cuts and Jobs Act was enacted on December 22, 2017. The Act reduces the US federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. The rate change is administratively effective at the beginning of our fiscal year, using a blended rate for the annual period. As a result, the blended statutory tax rate for the year is 24.5%. At March 31, 2018, we have not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. We have recognized a provisional benefit amount of $170.2 million related to the remeasurement of our deferred tax balance for the twenty-six week period ended March 31, 2018. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. In addition, we have recognized a provisional expense amount of $23.1 million for our one-time transition tax liability for the twenty-six week period ended March 31, 2018. The one-time transition tax is

based on our total post-1986 E&P that we previously deferred from US income taxes and is based in part on the amount of those earnings held in cash and other specified assets. However, we continue to refine the calculation of the total post-1986 E&P for our foreign subsidiaries. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from US federal taxation and finalize the amounts held in cash or other specified assets. As a result of the Act, we recognized a provisional benefit amount of $147.1 million as a discrete tax benefit, which is included as a component of income tax expense from continuing operations. The Company's lower effective tax rate for the twenty-six week period ended March 31, 2018 was due to the reduction in the U.S. federal corporate tax rate as well as the discrete adjustment related to the enactment of the Act described above.

Backlog
As of March 31,December 29, 2018, the Company estimated its sales order backlog at $1,869$2,181 million compared to an estimated sales order backlog of $1,648$1,706 million as of April 1,December 30, 2017. The increase in backlog is primarily due to growth from recent acquisitions and organic growth in both the defense market and the commercial aftermarket.aftermarket, commercial OEM and defense markets. The majority of the purchase orders outstanding

as of March 31,December 29, 2018 are scheduled for delivery within the next twelve months. Purchase orders may be subject to cancellation or deferral by the customer prior to shipment. The level of unfilled purchase orders at any given date during the year will be materially affected by the timing of the Company’s receipt of purchase orders and the speed with which those orders are filled. Accordingly, the Company’s backlog as of March 31,December 29, 2018 may not necessarily represent the actual amount of shipments or sales for any future period.
Foreign Operations
Although we manufacture a significant portion of our products in the United States, we manufacture some products in Belgium, China, Germany, Hungary, Japan, Malaysia, Mexico, Norway, Sri Lanka, Sweden, and the United Kingdom. We sell our products in the United States as well as in foreign countries. Although the majority of sales of our products are made to customers (including distributors) located in the United States, our products are ultimately sold to and used by customers, including airlines and other end users of aircraft, throughout the world. A number of risks inherent in international operations could have a material adverse effect on our results of operations, including currency fluctuations, difficulties in staffing and managing multi-national operations, general economic and political uncertainties and potential for social unrest in countries in which we operate, limitations on our ability to enforce legal rights and remedies, restrictions on the repatriation of funds, change in trade policies, tariff regulation, difficulties in obtaining export and import licenses and the risk of government financed competition.
There can be no assurance that foreign governments will not adopt regulations or take other action that would have a direct or indirect adverse impact on the business or market opportunities of the Company within such governments’ countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to our operations and growth strategy.
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 additional 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.
InThe 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 additional debt financing during the fiscal year ended September 30, 2018, and anticipated financing transactions described in the paragraphs below and in Note 16, "Subsequent Events," to the condensed consolidated financial statements, interest payments will increase going forward in accordance with the terms of the related debt agreements. However, in connection with the continued application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers), we expect our efforts will continue to generate strong margins and provide more than sufficient cash provided by operating activities to meet our interest obligations and liquidity needs.  We believe our cash provided by operating activities and available borrowing capacity will enable us to make opportunistic investments in our own stock, make strategic business combinations and/or pay dividends to our shareholders.
In connection with the merger agreement to acquire Esterline for approximately $4.0 billion, the Company entered into a commitment letter for a senior secured term facility up to $3.7 billion. On January 30, 2019, in lieu of the term loans borrowings contemplated by the commitment letter, the Company entered into a purchase agreement in connection with a private offering of $3.8 billion aggregate principal amount in 6.25% senior secured notes (“first secured notes offering”) due 2026. In addition, on February 1, 2019, the Company entered into a purchase agreement in connection with a private offering of $200 million aggregate principal amount of 6.25% senior secured notes (the “second secured notes offering”) due 2026. All $4.0 billion aggregate principal amount of the secured notes offering will constitute a single class of notes and will be issued under a single indenture offering. The first secured notes offering will be issued at a price of 100% of their principal amount and the second secured notes offering

will be issued at a price of 101% of their principal amount. The Notes will be guaranteed, with certain exceptions, by TransDigm Group, TransDigm UK and all of TransDigm Inc.’s existing and future U.S. subsidiaries on a senior subordinated basis or senior secured basis, as applicable. The Company expects the secured notes offerings to close on or about February 13, 2019, subject to customary closing conditions. The Company intends to use the net proceeds from the secured notes offerings to fund the purchase price of the Esterline acquisition.
All required regulatory reviews of the Esterline acquisition are complete, other than the European Commission antitrust review and the French foreign investment review. Subject to satisfactory completion of these reviews and other customary closing conditions, the Company currently expects the closing of the acquisition to occur in March or April 2019.
On February 1, 2019, the Company entered into a purchase agreement in connection with a private offering of $550 million in 7.50% new senior subordinated notes of TransDigm, Inc., a wholly-owned subsidiary of TransDigm Group, due in March 2027, pursuant to a confidential offering memorandum in a private placement under Rule 144A and Regulation S of the Securities Act of 1933. The offering is expected to close on February 13, 2019, subject to customary closing conditions. The net proceeds, plus existing cash on hand, are intended to be used to redeem all of the outstanding 2020 Notes. Upon the redemption of the 2020 notes, approximately $2 million of unamortized debt issuance costs will be written off.
In the future, the Company may increase its borrowings in connection with acquisitions, if cash flows from operating activities becomesbecome insufficient to fund current operations or for other short-term cash needs or for stock repurchases or special dividends. Our future leverage will also be impacted by the then current conditions of the credit markets.

During the third quarter of fiscal 2018, TransDigm UK, a wholly-owned, indirect subsidiary of TD Group, issued $500 million in aggregate principal amount of the TransDigm UK Notes at a discount of 0.76%. The TransDigm UK Notes bear interest at the rate of 6.875% per annum and mature on May 15, 2026.
On January 30, 2019, the Company entered into a purchase agreement in connection with a private offering of $3.8 billion aggregate principal amount in 6.25% senior secured notes due 2026 (the “first secured notes offering”). In addition, on February 1, 2019, the Company entered into a purchase agreement in connection with a private offering of $200 million aggregate principal amount of 6.25% senior secured notes due 2026 (the “second secured notes offering”). All $4.0 billion aggregate principal amount of the secured notes will constitute a single class and will be issued under a single indenture.

The net proceeds, plus existing cash on hand, are intended to be used to redeem all of the Company's outstanding 2020 Notes.
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. 3.5. 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 4.255.00 to 1.00, in each case, after giving effect to such incremental term loans or additional revolving commitments.
The Credit Agreement requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as defined in the Credit Agreement), commencing 90 days after the end of each fiscal year, subject to certain exceptions. In addition, subject to certain exceptions (including, with respect to asset sales, the reinvestment in productive assets), TransDigm will be required to prepay the loans outstanding under the Credit Agreement at 100% of the principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of certain asset sales and issuance or incurrence of certain indebtedness. No matters mandating prepayments occurred during the quarter ended March 31,December 29, 2018.
In addition, under the Credit Agreement, if the usage of the revolving credit facility exceeds 25% of the total revolving commitments, the Company will be required to maintain a maximum consolidated net leverage ratio of net debt, as defined, to trailing four-quarter EBITDA As Defined. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the Credit Agreement or the Indentures.
If any such default occurs, the lenders under the Credit Agreement and the holders of the Notes may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under the Credit Agreement also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the Credit Agreement, the lenders thereunder will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash, and they will also have the right to prevent us from making debt service payments on the Notes.
As of March 31,December 29, 2018, 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 one1 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. In August 2017,
On July 31, 2018, the Company amended the Securitization Facility to increase the borrowing capacity to $300$350 million and extend the maturity date to August 1, 2018.July 31, 2019. As of March 31,December 29, 2018, the Company has borrowed $300 million under the Securitization Facility. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.
Stock Repurchase Program
On November 8, 2017, our Board of Directors, authorized a new stock repurchase program replacing the previous $600 million program and permitting repurchases of our outstanding shares not to exceed $650 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes. No repurchases were made under the program during the quarter and year-to-date period ended March 31,December 29, 2018. As of December 29, 2018, the entire $650 million of repurchases allowable under the program remained, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.

Non-GAAP Financial Measures
We present below certain financial information based on our EBITDA and EBITDA As Defined. References to “EBITDA” mean earnings before interest, taxes, depreciation and amortization, and references to “EBITDA As Defined” mean EBITDA plus, as applicable for each relevant period, certain adjustments as set forth in the reconciliations of net income to EBITDA and EBITDA As Defined and the reconciliations of net cash provided by operating activities to EBITDA and EBITDA As Defined presented below.
Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under accounting principles generally accepted in the United States of America (“GAAP”). We present EBITDA and EBITDA As Defined because we believe they are useful indicators for evaluating operating performance and liquidity.
Our management believes that EBITDA and EBITDA As Defined are useful as indicators of liquidity because securities analysts, investors, rating agencies and others use EBITDA to evaluate a company’s ability to incur and service debt. In addition, EBITDA As Defined is useful to investors because the revolving credit facility under our senior secured credit facility requires compliance under certain circumstances, on a pro forma basis, with a financial covenant that measures the ratio of the amount of our secured indebtedness to the amount of our Consolidated EBITDA defined in the same manner as we define EBITDA As Defined herein.
In addition to the above, our management uses EBITDA As Defined to review and assess the performance of the management team in connection with employee incentive programs and to prepare its annual budget and financial projections. Moreover, our management uses EBITDA As Defined to evaluate acquisitions.
Although we use EBITDA and EBITDA As Defined as measures to assess the performance of our business and for the other purposes set forth above, the use of these non-GAAP financial measures as analytical tools has limitations, and you should not consider any of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with GAAP. Some of these limitations are:
neither EBITDA nor EBITDA As Defined reflects the significant interest expense, or the cash requirements, necessary to service interest payments on our indebtedness;
although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and neither EBITDA nor EBITDA As Defined reflects any cash requirements for such replacements;
the omission of the substantial amortization expense associated with our intangible assets further limits the usefulness of EBITDA and EBITDA As Defined;
neither EBITDA nor EBITDA As Defined includes the payment of taxes, which is a necessary element of our operations; and
EBITDA As Defined excludes the cash expense we have incurred to integrate acquired businesses into our operations, which is a necessary element of certain of our acquisitions.
Because of these limitations, EBITDA and EBITDA As Defined should not be considered as measures of discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by not viewing EBITDA or EBITDA As Defined in isolation and specifically by using other GAAP measures, such as net income, net sales and operating profit, to measure our operating performance. Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with GAAP. Our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
The information called for by this item is provided under the caption 'Description of Senior Secured Credit Facilities and Indentures' under Item 2 - "Management's Discussion and Analysis of Financial Condition and Results of Operations." Market risks are described more fully within “Quantitative and Qualitative Disclosures About Market Risk” in Part II, Item 7A of our most recent Form 10-K. These market risks have not materially changed since the date our most recent Form 10-K was filed with the SEC.
ITEM 4. CONTROLS AND PROCEDURES
As of March 31,December 29, 2018, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its President, and Chief Executive Officer and Director (Principal Executive Officer) and Executive Vice President and Interim Chief Financial Officer (Principal Financial and Accounting Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the President, and Chief Executive Officer and Executive Vice PresidentDirector and Interim Chief Financial Officer concluded that TD Group’s disclosure controls and procedures are effective to ensure that information required to be disclosed by TD Group in the reports it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to TD Group’s management, including President, and Chief Executive Officer and Executive Vice PresidentDirector and Interim Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, TD Group’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures. There have been no significant changes in TD Group’s internal controls or other factors that could significantly affect the internal controls subsequent to the date of TD Group’s evaluations.
Changes in Internal Control over Financial Reporting
There was no change in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended March 31,December 29, 2018, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. During the fiscal quarter ending March 31, 2018 and year-ended September 30, 2017, the Company completed the acquisition of Kirkhill and the Third Quarter 2017 Acquisitions. The Company is currently integrating these acquisitions into its operations, compliance programs and internal control processes. As permitted by SEC rules and regulations, the Company has excluded these acquisitions from management's evaluation of internal controls over financial reporting as of March 31, 2018. These acquisitions constituted less than 2% of the Company's total assets as of March 31, 2018, and less than 1% of the Company's net sales in the fiscal quarter ended March 31, 2018.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS
We and certain of our current or former officers and directors are defendants in a consolidated securities class action captioned In re TransDigm Group, Inc. Securities Litigation, Case No. 1:17-cv-01677-DCN (N.D. Ohio).  The cases were originally filed on August 10, 2017, and September 18, 2017 and were consolidated on December 5, 2017.  A consolidated amended complaint was filed on February 16, 2018. The plaintiffs allege that the defendants made false or misleading statements with respect to, or failed to disclose, the impact of certain alleged business practices in connection with sales to the U.S. government on the Company’s growth and profitability.  The plaintiffs assert claims under Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder and Section 20(a) of the Exchange Act, and seek unspecified monetary damages and other relief.  In addition, we, as nominal defendant, and certain of our current or former officers and directors are defendants in a shareholder derivative action captioned Sciabacucchi v. Howley et al., No. 1:17-cv-1971-DCN (N.D. Ohio). The case was filed on September 19, 2017.  The plaintiffs allege breach of fiduciary duty and other claims arising out of substantially the same actions or inactions alleged in the securities class actions described above. This action has been stayed pending the outcome of an anticipateda 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, 2017,2018, filed on November 13, 2017.9, 2018. There have been no material changes to the risk factors set forth therein.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS: PURCHASES OF EQUITY SECURITIES BY THE ISSUER
On November 8, 2017, our Board of Directors, authorized a new stock repurchase program replacing the previous $600 million program and permitting repurchases of our outstanding shares not to exceed $650 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes. No repurchases were made under the program during the thirteen and twenty-six week periodsperiod ended March 31,December 29, 2018. As of December 29, 2018, the entire $650 million of repurchases allowable under the program remained, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.
