UNAUDITED INTERIM FINANCIAL INFOMRATION	UNAUDITED INTERIM FINANCIAL INFORMATION The financial information included herein is unaudited; however, the information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s financial position and results of operations and cash flows for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the year ended September 30, 2015 included in TD Group’s Form 10-K filed on November 13, 2015. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“GAAP”). The September 30, 2015 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the twenty-six week period ended April 2, 2016 are not necessarily indicative of the results to be expected for the full year. Certain reclassifications have been made to the prior year financial statements to conform to current year classifications related to the adoption of new accounting pronouncements during the twenty-six week period ended April 2, 2016 impacting the classification of both debt issuance costs and deferred income taxes in the Condensed Consolidated Balance Sheets. The accounting pronouncements and impact of the adoption of the pronouncements are summarized in Note 4, "Recent Accounting Pronouncements" and Note 8, "Debt."

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS During the twenty-six week period ended April 2, 2016 and fiscal year ended September 30, 2015 , the Company completed the acquisitions of Breeze-Eastern Corporation ("Breeze-Eastern"), PneuDraulics, Inc. ("PneuDraulics"), the assets of the aerospace business of Pexco LLC (“Pexco Aerospace”), the aerospace business of Franke Aquarotter GmbH (now named Adams Rite Aerospace GmbH), and the Telair Cargo Group (“Telair”). The Company accounted for the acquisitions using the acquisition method and included the results of operations of the acquisitions in its consolidated financial statements from the effective date of each acquisition. As of April 2, 2016 , the purchase price allocations for Breeze-Eastern, PneuDraulics and Pexco remain preliminary as the Company completes its assessments of deferred taxes and accrued liabilities. Pro forma net sales and results of operations for the acquisitions had they occurred at the beginning of the applicable twenty-six week period s ended April 2, 2016 or March 28, 2015 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 . Breeze-Eastern – On January 4, 2016, a newly-formed subsidiary of TransDigm Inc. completed the tender offer of all of the outstanding stock of Breeze-Eastern for $19.61 per share in cash. Following consummation of the tender offer, the subsidiary was merged into Breeze-Eastern on January 4, 2016; in connection therewith, all outstanding stock of Breeze-Eastern was canceled and Breeze-Eastern became a wholly owned subsidiary of TransDigm Inc. The purchase price for the tender offer and the merger was approximately $205.9 million million, of which $146.4 million (net of cash acquired of $ 30.8 million ) was paid at closing and $28.7 million is accrued for payment to dissenting stockholders. Breeze-Eastern manufactures high performance lifting and pulling devices for military and civilian aircraft, including rescue hoists, winches and cargo hooks, and weapons-lifting systems. These products fit well with TransDigm’s overall business direction and Breeze-Eastern is included in TransDigm's Power & Control segment. The Company expects that approximately $106.7 million of goodwill recognized for the acquisition will not be deductible for tax purposes. PneuDraulics – On August 19, 2015, TransDigm Inc. acquired all of the outstanding stock of PneuDraulics for approximately $323.5 million in cash, less a purchase price adjustment of $2.0 million received in connection with a working capital settlement in the second quarter of fiscal 2016. PneuDraulics manufactures proprietary, highly engineered aerospace pneumatic and hydraulic components and subsystems for commercial transport, regional, business jet and military applications. These products fit well with TransDigm’s overall business direction. PneuDraulics is included in TransDigm’s Power & Control segment. The purchase price includes approximately $100.7 million of tax benefits to be realized by the Company over a 15 -year period that began in the fourth quarter of fiscal 2015, and the Company expects that approximately $222.4 million of goodwill recognized for the acquisition will be deductible for tax purposes. Pexco Aerospace – On May 14, 2015, Pexco Aerospace, Inc., a newly formed subsidiary of TransDigm Inc., acquired the assets of the aerospace business of Pexco LLC (“Pexco Aerospace”) for a total purchase price of approximately $496.4 million in cash, less a purchase price adjustment of $0.4 million received in connection with a working capital settlement in the fourth quarter of fiscal 2015. Pexco Aerospace manufactures extruded plastic interior parts for use in the commercial aerospace industry. These products fit well with TransDigm’s overall business direction. Pexco Aerospace is included in TransDigm’s Airframe segment. The purchase price includes approximately $166.4 million of tax benefits to be realized by TransDigm over a 15 -year period that began in the third quarter of fiscal 2015, and the Company expects that approximately $405.7 million of goodwill recognized for the acquisition will be deductible for tax purposes. Adams Rite Aerospace GmbH – On March 31, 2015, the Company’s Adams Rite subsidiary acquired the aerospace business of Franke Aquarotter GmbH (now known as Adams Rite Aerospace GmbH) for approximately $75.3 million in cash. Adams Rite Aerospace GmbH manufactures proprietary faucets and related products for use on commercial transports and regional jets. These products fit well with TransDigm’s overall business direction. Adams Rite Aerospace GmbH is included in TransDigm’s Airframe segment. Approximately $63.9 million of goodwill recognized for the acquisition is not deductible for tax purposes. Telair Cargo Group – On March 26, 2015, TransDigm Germany GmbH, a subsidiary of TransDigm Inc., acquired all of the outstanding stock of Telair International GmbH ("Telair International"), TransDigm Inc. acquired all of the outstanding stock of Nordisk Aviation Products ("Nordisk"), and Telair US LLC, a newly formed subsidiary of TransDigm Inc. ("Telair US"), acquired the assets of the AAR Cargo business (collectively, "Telair Cargo Group"). The total purchase price was approximately $730.9 million in cash, which included a net $7.7 million purchase price adjustment paid in the fourth quarter of fiscal 2015. Telair Cargo Group manufactures aerospace on-board cargo loading and handling, restraint systems and unit load devices for a variety of commercial and military platforms with positions on a wide range of new and existing aircraft. These products fit well with TransDigm’s overall business direction. The business consists of three major operating units: Telair International, Nordisk and Telair US. Telair International and Telair US are included in TransDigm’s Power & Control segment and Nordisk is included in TransDigm’s Airframe segment. The total purchase price of Telair Cargo Group 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 $ 143,643 Property, plant, and equipment 16,011 Intangible assets 205,000 Goodwill 483,390 Other 5,968 Total assets acquired $ 854,012 Liabilities assumed: Current liabilities $ 59,150 Other noncurrent liabilities 64,001 Total liabilities assumed $ 123,151 Net assets acquired $ 730,861 Approximately $33.2 million of goodwill recognized for the acquisition is deductible for tax purposes and approximately $450.2 million of goodwill recognized for the acquisition is not deductible for tax purposes.

RECENT ACCOUNTING PRONOUNCEMENT

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 which creates a new topic in the Accounting Standards Codification (“ASC”) 606, “Revenue From Contracts With Customers .” In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishes a new control-based revenue recognition model; changes the basis for deciding when revenue is recognized over time or at a point in time; provides new and more detailed guidance on specific topics; and expands and improves disclosures about revenue. The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2018. The Company is currently evaluating the impact that the update will have on its consolidated financial statements and disclosures. In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” which expands upon the guidance on the presentation of debt issuance costs. The guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The guidance does not change the requirements surrounding the recognition and measurement of debt issuance costs, and the amortization of debt issuance costs will continue to be reported as interest expense. The guidance is effective for the Company beginning October 1, 2016. However, as early adoption is permissible, the Company adopted the pronouncement effective October 1, 2015. The adoption of this pronouncement did not have a significant impact on our consolidated financial position and results of operations, although it did change the financial statement classification of debt issuance costs. In connection with adopting the pronouncement beginning October 1, 2015, the Company reclassified $77.7 million in debt issuance costs as of September 30, 2015, to Current portion of long-term debt and Long-term debt in the liabilities section of the Condensed Consolidated Balance Sheet. Refer to Note 8, "Debt," for the impact on the April 2, 2016 Condensed Consolidated Balance Sheet. In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," a new standard intended to simplify the accounting for measurement period adjustments in a business combination. Measurement period adjustments are changes to provisional amounts recorded when the accounting for a business combination is incomplete as of the end of a reporting period. The measurement period can extend for up to a year following the transaction date. During the measurement period, companies may make adjustments to provisional amounts when information necessary to complete the measurement is received. The new guidance requires companies to recognize these adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. Companies are no longer required to retroactively apply measurement period adjustments to all periods presented. The guidance is effective for the Company on October 1, 2016. However, as early adoption is permissible, the Company adopted the pronouncement beginning October 1, 2015. The adoption of this pronouncement did not have a significant impact on the Company's consolidated financial statements and disclosures. In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes,” which requires entities to present deferred tax assets and liabilities as noncurrent in a classified balance sheet. This guidance simplifies the current guidance, which requires entities to separately present deferred tax assets and liabilities as current and non-current in a classified balance sheet. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016, and interim periods within those years, and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. As early adoption is permissible, the Company adopted this pronouncement beginning October 1, 2015 and applied this pronouncement retrospectively. In connection with adopting the pronouncement beginning October 1, 2015, the Company reclassified $45.4 million from current deferred income tax assets in the Condensed Consolidated Balance Sheet as of September 30, 2015 to non-current deferred income tax liabilities. 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. The 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 its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements.

Income Tax Disclosure [Abstract]
INCOME TAXES	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 April 2, 2016 and March 28, 2015 , the effective income tax rate was 31.0% and 29.2% , respectively. During the twenty-six week period s ended April 2, 2016 and March 28, 2015 , the effective income tax rate was 30.5% and 30.8% , respectively. The Company’s higher effective tax rate for the thirteen week period ended April 2, 2016 was primarily due to a discrete adjustment in the prior year related to the IRS examination results for fiscal years 2012 and 2013. The Company’s lower effective tax rate for the twenty-six week period was primarily due to foreign earnings taxed at rates lower than the U.S. statutory rate partially offset by the prior year discrete adjustment related to the IRS examination results. The Company’s effective tax rate for these periods was less than the Federal statutory tax rate primarily due to the domestic manufacturing deduction and foreign earnings taxed at rates lower than the U.S. statutory rate. 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, 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 examination in Belgium for its fiscal years of 2013 and 2014. In addition, the Company is subject to state income tax examinations for fiscal years 2009 and later. At both April 2, 2016 and September 30, 2015 , TD Group had $6.9 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $6.7 million and $6.5 million on the effective tax rate at April 2, 2016 and September 30, 2015 , respectively. The Company believes the tax positions that comprise the unrecognized tax benefits will be reduced by approximately $1.6 million over the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	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): April 2, 2016 September 30, 2015 Level Carrying Amount Fair Value Carrying Amount Fair Value Assets: Cash and cash equivalents 1 $ 612,015 $ 612,015 $ 714,033 $ 714,033 Interest rate cap agreements (1) 2 3,460 3,460 8,180 8,180 Liabilities: Interest rate swap agreements (2) 2 31,910 31,910 24,770 24,770 Interest rate swap agreements (3) 2 52,870 52,870 49,730 49,730 Short-term borrowings - trade receivable securitization facility (4) 1 199,895 199,895 199,792 199,792 Long-term debt, including current portion: Term loans (4) 2 4,316,876 4,299,361 4,333,682 4,344,000 2020 Notes (4) 1 545,173 551,375 544,645 520,000 2021 Notes (4) 1 496,535 522,500 496,211 524,000 2022 Notes (4) 1 1,140,899 1,144,250 1,140,179 1,081,000 2024 Notes (4) 1 1,190,194 1,200,000 1,189,606 1,119,000 2025 Notes (4) 1 445,721 444,375 445,487 417,000 (1) Included in Other non-current assets on the Condensed Consolidated Balance Sheet. (2) Included in Accrued liabilities on the Condensed Consolidated Balance Sheet. (3) Included in Other non-current liabilities on the Condensed Consolidated Balance Sheet. (4) The carrying amount of the debt instrument is presented net of the debt issuance costs in connection with the Company's adoption of ASU 2015-03. Refer to Note 8, "Debt," for gross carrying amounts. The Company values its financial instruments using an industry standard market approach, in which prices and other relevant information is 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 2020 Notes, 2021 Notes, 2022 Notes, 2024 Notes and 2025 Notes were based upon quoted market prices. 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 April 2, 2016 and September 30, 2015 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	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 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. At April 2, 2016 , five interest rate swap agreements beginning March 31, 2016 were in place to hedge the variable interest rates on the 2014 Term Loans for a fixed rate based on an aggregate notional amount of $750 million through June 30, 2020. These interest rate swap agreements convert the variable interest rate on the aggregate notional amount of the 2014 Term Loans to a fixed rate of 5.8% ( 2.8% plus the 3% margin percentage ) over the term of the interest rate swap agreements. At April 2, 2016 , six interest rate cap agreements beginning September 30, 2015 were in place to offset the variable interest rates on the 2015 Term Loans based on an aggregate notional amount of $750 million . These interest rate cap agreements offset the variability in expected future cash flows on the Company's variable rate debt attributable to fluctuations above the three month LIBO rate of 2.5% through June 30, 2020. At April 2, 2016 , three interest rate swap agreements beginning September 30, 2014 were in place to hedge the variable interest rates on the 2014 Term Loans for a fixed rate based on an aggregate notional amount of $1.0 billion through June 30, 2019. These interest rate swap agreements converted the variable interest rate on the aggregate notional amount of the 2014 Term Loans to a fixed rate of 5.4% ( 2.4% plus the 3% margin percentage ) over the term of the interest rate swap agreements. In connection with the refinancing of the 2011 Term Loans, the Company no longer designated the interest rate swap agreements relating to the $353 million aggregate notional amount as cash flow hedges for accounting purposes. Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss in stockholder’s deficit amortized into earnings totaled $2.1 million for the twenty-six week period ended March 28, 2015 . There is no remaining amortization for these dedesignated swap agreements as of September 30, 2015 . Based on the fair value amounts of the interest rate swap agreements determined as of April 2, 2016 , the estimated net amount of existing gains and losses expected to be reclassified into interest expense within the next twelve months is approximately $31.9 million .

SEGMENTS

Segment Reporting [Abstract]
SEGMENTS	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, 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, 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, and refueling systems for heavy equipment used in mining, construction and other industries. Primary customers of this segment are off-road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers and manufacturers of heavy equipment used in mining, construction and other industries. The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items including refinancing costs, acquisition-related costs, transaction-related costs and non-cash compensation charges incurred in connection with the Company’s stock incentive plans. Acquisition-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction related costs comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments. EBITDA As Defined is not a measurement of financial performance under 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 which creates a new topic in the Accounting Standards Codification (“ASC”) 606, “Revenue From Contracts With Customers .” In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishes a new control-based revenue recognition model; changes the basis for deciding when revenue is recognized over time or at a point in time; provides new and more detailed guidance on specific topics; and expands and improves disclosures about revenue. The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2018. The Company is currently evaluating the impact that the update will have on its consolidated financial statements and disclosures. In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” which expands upon the guidance on the presentation of debt issuance costs. The guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The guidance does not change the requirements surrounding the recognition and measurement of debt issuance costs, and the amortization of debt issuance costs will continue to be reported as interest expense. The guidance is effective for the Company beginning October 1, 2016. However, as early adoption is permissible, the Company adopted the pronouncement effective October 1, 2015. The adoption of this pronouncement did not have a significant impact on our consolidated financial position and results of operations, although it did change the financial statement classification of debt issuance costs. In connection with adopting the pronouncement beginning October 1, 2015, the Company reclassified $77.7 million in debt issuance costs as of September 30, 2015, to Current portion of long-term debt and Long-term debt in the liabilities section of the Condensed Consolidated Balance Sheet. Refer to Note 8, "Debt," for the impact on the April 2, 2016 Condensed Consolidated Balance Sheet. In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," a new standard intended to simplify the accounting for measurement period adjustments in a business combination. Measurement period adjustments are changes to provisional amounts recorded when the accounting for a business combination is incomplete as of the end of a reporting period. The measurement period can extend for up to a year following the transaction date. During the measurement period, companies may make adjustments to provisional amounts when information necessary to complete the measurement is received. The new guidance requires companies to recognize these adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. Companies are no longer required to retroactively apply measurement period adjustments to all periods presented. The guidance is effective for the Company on October 1, 2016. However, as early adoption is permissible, the Company adopted the pronouncement beginning October 1, 2015. The adoption of this pronouncement did not have a significant impact on the Company's consolidated financial statements and disclosures. In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes,” which requires entities to present deferred tax assets and liabilities as noncurrent in a classified balance sheet. This guidance simplifies the current guidance, which requires entities to separately present deferred tax assets and liabilities as current and non-current in a classified balance sheet. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016, and interim periods within those years, and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. As early adoption is permissible, the Company adopted this pronouncement beginning October 1, 2015 and applied this pronouncement retrospectively. In connection with adopting the pronouncement beginning October 1, 2015, the Company reclassified $45.4 million from current deferred income tax assets in the Condensed Consolidated Balance Sheet as of September 30, 2015 to non-current deferred income tax liabilities. 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. The 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 its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements.
