Income Taxes	Note 14. Income Taxes We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in evaluating our uncertain tax positions and determining our provision for income taxes. Our total unrecognized tax benefits were $1,564 million and $1,654 million as of December 31, 2011 and March 31, 2012. Our total unrecognized tax benefits that, if recognized, would affect our effective tax rate were $1,350 million and $1,434 million as of December 31, 2011 and March 31, 2012. Our existing tax positions will continue to generate an increase in liabilities for unrecognized tax benefits. Our effective tax rate could fluctuate significantly on a quarterly basis and could be adversely affected to the extent earnings are lower than anticipated in countries that have lower statutory rates and higher than anticipated in countries that have higher statutory rates. Our effective tax rate could also fluctuate due to the net gains and losses recognized by legal entities on certain hedges and related hedged intercompany and other transactions under our foreign exchange risk management program, by changes in the valuation of our deferred tax assets or liabilities, or by changes in tax laws, regulations, or accounting principles, as well as certain discrete items. In addition, we are subject to the continuous examination of our income tax returns by the IRS and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes.
