New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS Leases In February 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use asset, representing the right to use the underlying asset for the lease term, and a lease liability on the balance sheet for all leases with terms greater than 12 months. Lessees can forgo recognizing a right-of-use asset and lease liability with lease terms of 12 months or less on the balance sheet through accounting policy elections as long as the lease does not include options to renew or purchase the underlying assets that are reasonably certain to be exercised. The new guidance also requires certain qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases, along with additional key information about leasing arrangements. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, to clarify certain aspects of the new lease standard. The FASB also issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which allows the election of an optional transition method to apply the provisions of the new lease standard as of the date of adoption and recognize a cumulative-effect adjustment to retained earnings in the period of adoption, while continuing to present all prior periods under previous lease accounting guidance. In December 2018, the FASB issued ASU No. 2018-20, Leases (842): Narrow-Scope Improvements for Lessors, which clarifies how to account for sales tax and similar taxes collected from lessees, certain lessor costs and recognition of variable payments for contracts with lease and non-lease components. The aforementioned lease standards and amendments ("the new lease standard") are required to be adopted for annual periods beginning after December 15, 2018, including interim periods within that annual period, which is our fiscal year 2020. The new lease standard is to be applied using a modified retrospective approach, which includes a number of optional practical expedients and an optional transition method. Early adoption is permitted. We intend to adopt the new lease standard for our fiscal year 2020. We are currently evaluation our lease portfolio; assessing system needs to support adoption of the new lease standard; and analyzing procedural changes, including updating our lease accounting policy as needed to reflect the new requirements of this standard. We continue to evaluate the impact that these changes in methodology will have on our financial condition, results of operations and disclosures. Other In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the accounting for credit losses on instruments measured at amortized cost by adding an impairment model that is based on expected losses rather than incurred losses. An entity will recognize as an allowance its estimate of expected credit losses, which is believed to result in more timely recognition of such losses as the standard eliminates the probable initial recognition threshold. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments–Credit Losses, which clarifies that a receivable arising from an operating lease that is accounted for by a lessor in accordance with Topic 842 is not within the scope of Subtopic 326. These standards are required to be adopted for annual periods beginning after December 15, 2019, including interim periods within that annual period, which is our fiscal year 2021. The amendments are to be applied using a modified retrospective approach as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which adopted. Early adoption is permitted for annual periods beginning after December 15, 2018, including interim periods within that annual period, which is our fiscal year 2020. We have not yet evaluated the impact the adoption of this guidance may have on our financial condition, results of operations or disclosures. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework–Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, amends and adds disclosure requirements for fair value measurements. The standard is required to be adopted for annual periods beginning after December 15, 2019, including interim periods within that annual period, which is our fiscal year 2021. Certain disclosures in the amendment are to be applied using a retrospective approach while other disclosures are to be applied using a prospective approach. Early adoption is permitted. We have not yet evaluated the impact the adoption of this guidance may have on our financial condition, results of operations or disclosures. In August 2018, the FASB issued ASU No. 2018-14, Compensation–Retirement Benefits–Defined Benefit Plans–General (Subtopic 715-20): Disclosure Framework–Changes to the Disclosure Requirements for Defined Benefit Plans, which eliminates, amends and adds disclosure requirements for defined benefit pension and other postretirement plans. The standard is required to be adopted for annual periods ending after December 15, 2020, which is our fiscal year 2021. The amendment is to be applied using a retrospective approach with early adoption permitted. We have not yet evaluated the impact the adoption of this guidance may have on our financial condition, results of operations or disclosures. Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), followed by related amendments (collectively, "the new revenue standard" or "ASC 606") to provide a single, comprehensive revenue recognition model for all contracts with customers. Under the new revenue standard, a company recognizes revenue to depict the transfer of promised goods or services to a customer in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. Determination of when and how revenue is recognized is based on a five-step analysis. Enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from a company's contracts with customers are required. We adopted the new revenue standard on September 30, 2018 for our fiscal year 2019 under the modified retrospective transition method. As of September 30, 2018, we recorded a cumulative-effect reduction to the opening balance of our fiscal year 2019 retained earnings of $6,227, net of tax, for the net deferral of previously recognized revenue and related cost of sales, partially offset by the capitalization and deferral of pre-contract costs. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. See Note 3 for our new revenue recognition accounting policy and disclosures relative to this guidance. In March 2016, the FASB issued ASU No. 2016-04, Liabilities—Extinguishments of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products, which amends existing guidance on extinguishing financial liabilities for certain prepaid stored-value products. The new standard requires recognition of the expected breakage amount or the value that is ultimately not redeemed either proportionally in earnings as redemption occurs or when redemption is remote, if issuers are not entitled to breakage. We adopted the new standard on a modified retrospective basis for the annual period ending September 28, 2019, including interim periods within that annual period. The adoption of this guidance had no impact on our financial condition, results of operations or disclosures. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory, which requires companies to account for the income tax effects of intercompany sales and transfers of assets other than inventory when the transfer occurs. Current guidance requires companies to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized. We adopted the new standard on a modified retrospective basis for the annual period ending September 28, 2019, including interim periods within that annual period. The adoption of this guidance had no impact on our financial condition, results of operations or disclosures. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changes how employers that sponsor defined benefit pension or other postretirement benefit plans present the net periodic benefit cost in the income statement. The new guidance requires the service cost component of net periodic benefit cost to be presented in the same income statement line items as other employee compensation costs arising from services rendered during the period, with only the service cost component eligible for capitalization in assets. Other components of the net periodic benefit cost are to be stated separately from the line items that include the service cost and outside of operating income. These components are not eligible for capitalization in assets. We adopted the new standard for the annual period ending September 28, 2019, including interim periods within that annual period, retrospectively for the presentation in the income statement of the service cost component and the other components of net periodic pension cost and prospectively for the capitalization in assets of the service cost component of net periodic pension cost. The adoption of this guidance did not have a material impact on our current or prior year financial condition, results of operations or disclosures. Therefore, the comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends the hedge accounting model in Accounting Standards Codification (ASC) 815 to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. We early adopted the new standard on a modified retrospective basis for the annual period ending September 28, 2019, including interim periods within that annual period. The adoption of this guidance had no impact on our current or prior year financial condition, results of operations or disclosures.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Leases

In February 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use asset, representing the right to use the underlying asset for the lease term, and a lease liability on the balance sheet for all leases with terms greater than 12 months. Lessees can forgo recognizing a right-of-use asset and lease liability with lease terms of 12 months or less on the balance sheet through accounting policy elections as long as the lease does not include options to renew or purchase the underlying assets that are reasonably certain to be exercised. The new guidance also requires certain qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases, along with additional key information about leasing arrangements.

In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, to clarify certain aspects of the new lease standard. The FASB also issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which allows the election of an optional transition method to apply the provisions of the new lease standard as of the date of adoption and recognize a cumulative-effect adjustment to retained earnings in the period of adoption, while continuing to present all prior periods under previous lease accounting guidance.

In December 2018, the FASB issued ASU No. 2018-20, Leases (842): Narrow-Scope Improvements for Lessors, which clarifies how to account for sales tax and similar taxes collected from lessees, certain lessor costs and recognition of variable payments for contracts with lease and non-lease components.

The aforementioned lease standards and amendments ("the new lease standard") are required to be adopted for annual periods beginning after December 15, 2018, including interim periods within that annual period, which is our fiscal year 2020. The new lease standard is to be applied using a modified retrospective approach, which includes a number of optional practical expedients and an optional transition method. Early adoption is permitted. We intend to adopt the new lease standard for our fiscal year 2020. We are currently evaluation our lease portfolio; assessing system needs to support adoption of the new lease standard; and analyzing procedural changes, including updating our lease accounting policy as needed to reflect the new requirements of this standard. We continue to evaluate the impact that these changes in methodology will have on our financial condition, results of operations and disclosures.

Adopted

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), followed by related amendments (collectively, "the new revenue standard" or "ASC 606") to provide a single, comprehensive revenue recognition model for all contracts with customers. Under the new revenue standard, a company recognizes revenue to depict the transfer of promised goods or services to a customer in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. Determination of when and how revenue is recognized is based on a five-step analysis. Enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from a company's contracts with customers are required.

We adopted the new revenue standard on September 30, 2018 for our fiscal year 2019 under the modified retrospective transition method. As of September 30, 2018, we recorded a cumulative-effect reduction to the opening balance of our fiscal year 2019 retained earnings of $6,227, net of tax, for the net deferral of previously recognized revenue and related cost of sales, partially offset by the capitalization and deferral of pre-contract costs. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. See Note 3 for our new revenue recognition accounting policy and disclosures relative to this guidance.

In March 2016, the FASB issued ASU No. 2016-04, Liabilities—Extinguishments of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products, which amends existing guidance on extinguishing financial liabilities for certain prepaid stored-value products. The new standard requires recognition of the expected breakage amount or the value that is ultimately not redeemed either proportionally in earnings as redemption occurs or when redemption is remote, if issuers are not entitled to breakage. We adopted the new standard on a modified retrospective basis for the annual period ending September 28, 2019, including interim periods within that annual period. The adoption of this guidance had no impact on our financial condition, results of operations or disclosures.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory, which requires companies to account for the income tax effects of intercompany sales and transfers of assets other than inventory when the transfer occurs. Current guidance requires companies to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized. We adopted the new standard on a modified retrospective basis for the annual period ending September 28, 2019, including interim periods within that annual period. The adoption of this guidance had no impact on our financial condition, results of operations or disclosures.

In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changes how employers that sponsor defined benefit pension or other postretirement benefit plans present the net periodic benefit cost in the income statement. The new guidance requires the service cost component of net periodic benefit cost to be presented in the same income statement line items as other employee compensation costs arising from services rendered during the period, with only the service cost component eligible for capitalization in assets. Other components of the net periodic benefit cost are to be stated separately from the line items that include the service cost and outside of operating income. These components are not eligible for capitalization in assets. We adopted the new standard for the annual period ending September 28, 2019, including interim periods within that annual period, retrospectively for the presentation in the income statement of the service cost component and the other components of net periodic pension cost and prospectively for the capitalization in assets of the service cost component of net periodic pension cost. The adoption of this guidance did not have a material impact on our current or prior year financial condition, results of operations or disclosures. Therefore, the comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends the hedge accounting model in Accounting Standards Codification (ASC) 815 to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. We early adopted the new standard on a modified retrospective basis for the annual period ending September 28, 2019, including interim periods within that annual period. The adoption of this guidance had no impact on our current or prior year financial condition, results of operations or disclosures.
