Income Tax Disclosure [Abstract]
Income taxes	Note 8. Income taxes Our consolidated effective income tax rates for the third quarter and first nine months of 2016 were 30.3% and 25.8%, respectively. In 2015, our effective income tax rates were 32.3% for the third quarter and 31.6% for the first nine months. Our effective income tax rate normally reflects benefits from the recurring impact of (a) dividends received deductions applicable to certain investments in equity securities, (b) income production tax credits from wind-powered electricity generation placed in service in the U.S. and (c) lower income tax rates applicable to earnings of certain foreign subsidiaries. As discussed in Notes 3 and 9 to these Consolidated Financial Statements, on February 29, 2016, we exchanged our long-held investment in P&G common stock for the common stock of Duracell. This exchange produced a pre-tax gain of $1.1 billion for financial reporting purposes. The exchange transaction was structured as a tax-free reorganization under the Internal Revenue Code. As a result, no income taxes are currently payable on the excess of the fair value of the business received over the tax basis of the P&G shares exchanged and we recorded a one-time reduction of certain deferred income tax liabilities (approximately $750 million) that were recorded in 2005 in connection with our exchange of The Gillette Company common stock for P&G common stock upon the merger of those two companies. The P&G/Duracell exchange produced a 4.7 percentage point reduction in our consolidated effective income tax rate for the first nine months of 2016.
