New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Changes In Accounting Principles	CHANGES IN ACCOUNTING PRINCIPLES In March 2018, the FASB issued guidance that clarifies application of Topic 740 in regards to the "Tax Cuts and Jobs Act" (the "Tax Act") enacted December 22, 2017. The guidance requires provisional amounts to be reported within the reporting period in which the Tax Act was enacted if a reasonable estimate can be determined or within the measurement period not to exceed one year from the enactment date by which accounting is required to be completed in accordance with Topic 740. Any provisional amounts or adjustments to provisional amounts reported in the measurement period should be included in income from continuing operations as an adjustment to tax expense or benefit in the reporting period the amounts are determined. The guidance was effective immediately and we adopted this guidance in the first quarter of fiscal 2018. The impact of adoption had a material impact to our financial statements (see Note 9: Income Taxes). In February 2018, the FASB issued guidance that allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2018, our fiscal 2020. Early adoption is permitted and entities will have the choice to apply either in the period of adoption or retrospectively to each period in which the effect of the change in the federal income tax rate in the Tax Act. We adopted this guidance in the fourth quarter of fiscal 2018 resulting in a reclass increasing Accumulated Other Comprehensive Income and decreasing Retained Earnings by $13 million in our consolidated financial statements. In March 2016, the FASB issued guidance that simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows and impact on earnings per share. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2016, our fiscal 2018. We adopted this guidance in the first quarter of fiscal 2018. The guidance requires all income tax effects of share-based payment awards to be recognized in the consolidated statements of income when the awards vest or are settled, which is a change from the previous guidance that required such activity to be recorded in capital in excess of par value within stockholders' equity. We adopted this guidance prospectively which may create volatility in our effective tax rate when adopted depending largely on future events and other factors, which may include our stock price, timing of stock option exercises, and the value realized upon vesting or exercise of shares compared to the grant date fair value of those shares. For the year ended September 29, 2018, the recorded tax benefit was not material. In addition, when calculating potential common shares used to determine diluted earnings per share this guidance requires that assumed proceeds under the treasury stock method be modified to exclude the amount of excess tax benefits that would have been recognized in additional paid-in capital. These changes were applied on a prospective basis which did not have a material impact to diluted earnings per share for the year ended September 29, 2018. Under the new guidance, companies can also make an accounting policy election to either estimate forfeitures each period or to account for forfeitures as they occur. We changed our accounting policy to account for forfeitures as they occur using the modified retrospective transition method which did not have a material impact on our consolidated financial statements. The guidance changes the presentation of excess tax benefits from a financing activity to an operating activity in the consolidated statements of cash flows. This guidance also requires the presentation related to cash paid to a taxing authority when shares are withheld to satisfy the statutory income tax withholding obligation to a financing activity in the consolidated statements of cash flows. We applied these changes prospectively, and thus, prior periods have not been adjusted. The adoption of this standard did not have a material impact on our consolidated statements of cash flows. In July 2015, the FASB issued guidance that requires management to evaluate inventory at the lower of cost and net realizable value. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2016, our fiscal 2018. The prospective transition method was applied. We adopted this guidance in the first quarter of fiscal 2018 and it did not have a material impact on our consolidated financial statements.
