Disclosure Text Block [Abstract]
Basis of Presentation And Recently Issued Accounting Pronouncements	In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary for a fair presentation of operating results for the interim periods presented. Adjustments consist of normal and recurring accruals. The consolidated financial statements are presented in accordance with the requirements of Form 10-Q and consequently do not include all disclosures required for annual financial statements presented in conformity with U.S. generally accepted accounting principles (GAAP). For further information, refer to the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 2017 . On December 22, 2017, the U.S. government enacted tax reform, the Tax Cuts and Jobs Act (the “Act”), which made comprehensive changes to federal income tax laws by moving from a global to a modified territorial tax regime. The Act includes a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent along with the elimination of certain deductions and credits, and a one-time “deemed repatriation” of accumulated foreign earnings. In the first quarter, the Company recognized a net tax benefit of $43 ( $0.07 per share) due to impacts of the Act, consisting of a $98 benefit on revaluation of net deferred income tax liabilities to the lower tax rate, and $185 of expense for the tax on deemed repatriation of accumulated foreign earnings and withholding taxes partially offset by $130 accrued in previous periods for the planned repatriation of non-U.S. cash. Given the complexities associated with the Act, the ultimate effects on repatriation cost and other tax items may differ materially from these provisional amounts due to additional regulatory guidance that may be issued and further evaluation of the Company’s actions, assumptions and interpretations. The effective tax rate for full year 2018 is currently expected to be approximately 25 to 27 percent . In 2019 and thereafter, the tax rate is expected to be approximately 25 percent . In the first quarter of fiscal 2018, the Company adopted updates to ASC 330, Inventory , which changed the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. These updates did not materially impact the Company's financial statements. In the first quarter of fiscal 2018, the Company adopted updates to ASC 740, Income Taxes , requiring recognition of the income tax effects of intra-entity transfers of assets other than inventory when the transfer occurs. These updates were adopted on a modified retrospective basis and did not materially impact the Company's financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Following is a discussion regarding the Company’s use of financial instruments: Hedging Activities – As of December 31, 2017 , the notional amount of foreign currency hedge positions was approximately $1.6 billion , and commodity hedge contracts totaled approximately $124 (primarily 49 million pounds of copper and aluminum). All derivatives receiving deferral accounting are cash flow hedges. The majority of hedging gains and losses deferred as of December 31, 2017 are expected to be recognized over the next 12 months as the underlying forecasted transactions occur. Gains and losses on foreign currency derivatives reported in other deductions, net reflect hedges of balance sheet exposures that do not receive deferral accounting. The following gains and losses are included in earnings and other comprehensive income (OCI) for the three months ended December 31, 2017 and 2016 : Into Earnings Into OCI 1st Quarter 1st Quarter Gains (Losses) Location 2016 2017 2016 2017 Commodity Cost of sales $ (2 ) 5 10 13 Foreign currency Sales, cost of sales (10 ) — 2 (12 ) Foreign currency Other deductions, net 6 — Total $ (6 ) 5 12 1 Regardless of whether derivatives receive deferral accounting, the Company expects hedging gains or losses to be essentially offset by losses or gains on the related underlying exposures. The amounts ultimately recognized will differ from those presented above for open positions, which remain subject to ongoing market price fluctuations until settlement. Derivatives receiving deferral accounting are highly effective and no amounts were excluded from the assessment of hedge effectiveness. Hedge ineffectiveness was immaterial for the three months ended December 31, 2017 and 2016 . Fair Value Measurement – Valuations for all derivatives and the Company's long-term debt fall within Level 2 of the GAAP valuation hierarchy. As of December 31, 2017 , the fair value of long-term debt was $4,092 , which exceeded the carrying value by $278 . At December 31, 2017 , the fair values of commodity contracts and foreign currency contracts were reported in other current assets and accrued expenses. Valuations of derivative contract positions are summarized below: September 30, 2017 December 31, 2017 Assets Liabilities Assets Liabilities Foreign Currency $ 26 18 11 19 Commodity $ 12 — 20 — Counterparties to derivatives arrangements are companies with investment-grade credit ratings. The Company has bilateral collateral arrangements with counterparties with credit rating-based posting thresholds that vary depending on the arrangement. If credit ratings on the Company's debt fall below pre-established levels, counterparties can require immediate full collateralization of all derivatives in net liability positions. The maximum amount that could potentially have been required was $11 . The Company also can demand full collateralization of derivatives in net asset positions should any counterparty credit ratings fall below certain thresholds. No collateral was posted with counterparties and none was held by the Company as of December 31, 2017 .
