| Income Taxes [Text Block] | Income Taxes For interim income tax reporting we estimate our annual effective tax rate and apply it to our year to date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2006 to 2015 with various significant tax jurisdictions. In the three months ended March 31, 2016 income tax expense of $559 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation of $775 million, partially offset by tax benefits related to tax audit settlements and deductions taken for stock investments in non-U.S. affiliates. In the three months ended March 31, 2015 income tax expense of $529 million primarily resulted from tax expense attributable to entities included in our effective tax rate calculation. At March 31, 2016 we had $35.8 billion of net deferred tax assets consisting of: (1) net operating losses and income tax credits; (2) capitalized research expenditures; and (3) other timing differences that are available to offset future income tax liabilities. |
