Accounting Changes and Error Corrections [Abstract]
Accounting Changes	Accounting Changes New Accounting Principles Adopted On October 1, 2016, the Company prospectively adopted amended requirements issued by the Financial Accounting Standards Board ("FASB") relating to the timing of recognition and classification of share-based compensation award-related income tax effects. Upon the settlement of awards in the first quarter of fiscal year 2017, the Company recorded a tax benefit of $27 million to Income tax provision within its consolidated statement of income. The Company expects to record additional tax benefits throughout fiscal year 2017. These tax benefits were recorded within Capital in excess of par value on the Company's condensed consolidated balance sheet in the prior-year period. Because these excess tax benefits are no longer recorded in Capital in excess of par value, the current-year period adjustment for the dilutive impact of share equivalents from share-based plans, which is used in the Company's computation of diluted earnings per share, increased by approximately 1 million shares. Also per the amended guidance, the Company classified the $27 million of excess tax benefits on its condensed consolidated statement of cash flows within Net Cash Provided by Operating Activities, rather than Net Cash Used for Financing Activities, which included the excess tax benefits for the first quarter of fiscal year 2016. The amended guidance allows entities to account for award forfeitures as they occur; however, the Company has elected to continue its determination of compensation cost recognized in each period based upon an estimate of expected future forfeitures. New Accounting Principles Not Yet Adopted In February 2016, the FASB issued a new lease accounting standard which requires lessees to recognize lease assets and lease liabilities on the balance sheet. The new standard also requires expanded disclosures regarding leasing arrangements. The Company is currently evaluating the impact that this new lease accounting standard will have on its consolidated financial statements upon its adoption of the standard on October 1, 2019. In May 2014, the FASB issued a new revenue recognition standard. Under this standard, revenue will be recognized upon the transfer of goods or services to customers and the amount of revenue recognized will reflect the consideration to which a reporting entity expects to be entitled in exchange for those goods or services. The Company intends to adopt the standard, as required, on October 1, 2018 and is currently in the process of completing the initial assessment of the impact that this new revenue recognition standard will have on its consolidated financial statements.
