Income Taxes	Income Taxes The effective tax rate for the three months ended March 31, 2012 and 2011 was 9.3% and 30.9%, respectively. The effective tax rate for the three months ended March 31, 2012 includes a $17 million tax benefit from the sale of non-U.S. leveraged lease assets and $22 million of tax benefits arising from the conclusion of tax examinations. The effective tax rate for the three months ended March 31, 2011 includes a $9 million tax benefit arising from a favorable conclusion of a foreign tax examination. As is the case with other large corporations, our tax returns are examined each year by tax authorities in the United States, other countries and local jurisdictions in which we have operations. Except for issues arising out of partnership investments, the IRS examination of tax years 2001-2004 is closed to audit and the examination of years 2005-2008 is expected to be closed to audit by the end of 2012. We have other domestic and international tax filings currently under examination or subject to examination. We regularly assess the likelihood of tax adjustments in each of the tax jurisdictions in which we have operations and account for the related financial statement implications. We believe we have established tax reserves that are appropriate given the possibility of tax adjustments. However, determining the appropriate level of tax reserves requires judgment regarding the uncertain application of tax law and the possibility of tax adjustments. Future changes in tax reserve requirements could have a material impact, positive or negative, on our results of operations, financial position and cash flows.
