Income Taxes	Income Taxes The effective tax rates were (10.5)% and 32.1% for the quarters ended June 30, 2013 and 2012, respectively and 0.7% and (191.3)% for the six months ended June 30, 2013 and 2012, respectively. The company records income taxes using an estimated annual effective tax rate for interim reporting. Under the annual effective tax rate method, jurisdictions with a projected loss where no tax benefit can be recognized are excluded from the calculation of the estimated annual effective tax rate. The effective tax rates for the six months ended June 30, 2013 and 2012 were impacted by the mix in earnings among domestic and foreign jurisdictions, losses in various jurisdictions and certain discrete items. Many of these foreign jurisdictions have tax rates that are lower than the U.S. statutory rate, and the company continues to maintain full valuation allowances on net deferred tax assets in certain of these foreign jurisdictions. The effective tax rate for the second quarter and six months ended June 30, 2013 was also impacted by the company continuing to maintain a full valuation allowance on U.S. net deferred tax assets. In the fourth quarter of 2012, the company recorded a valuation allowance against most of its U.S. federal and state deferred tax assets, which are primarily net operating losses ("NOLs"). In the quarter ended June 30, 2013, the company recorded out of period adjustments including $3 million of income tax benefit related to 2012 and 2011. In the first six months of 2012, the company recorded out of period adjustments, which included $3 million of income tax expense related to 2011 and 2010 in the first quarter of 2012. These corrections had an insignificant effect on all affected annual and quarterly periods and financial statement line items based on a quantitative and qualitative evaluation.
