Income Taxes	Income Taxes The effective tax rate for the three months ended September 30, 2013 and 2012 was 12.3% and 24.8%, respectively, and the effective tax rate for the nine months ended September 30, 2013 and 2012 was 19.1% and 20.8%, respectively. The effective tax rate for the three and nine months ended September 30, 2013 includes a tax benefit of $13 million from an affiliate reorganization and benefits of $4 million and $11 million, respectively, related to tax planning initiatives. The effective tax rate for the nine months ended September 30, 2013 also includes benefits of $5 million from the adjustment of non-U.S. tax accounts from prior periods and $4 million from the retroactive effect of 2013 U.S. tax legislation. The effective tax rate for the three and nine months ended September 30, 2012 includes tax benefits of $36 million and $58 million, respectively, from the resolution of tax examinations and tax accruals of $28 million for the repatriation of non-U.S. earnings. The effective tax rate for the nine months ended September 30, 2012 also includes tax benefits of $17 million from the sale of non-U.S. leveraged lease assets As is the case with other large corporations, our tax returns are examined each year by tax authorities in the U.S., other countries and local jurisdictions in which we have operations. We expect the examination of our 2009 through 2011 tax returns by the Internal Revenue Service (IRS) to be completed within the next 12 months. We regularly assess the likelihood of tax adjustments in each of the tax jurisdictions in which we do business 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. It is reasonably possible that the amount of our unrecognized tax benefits will decrease in the next 12 months, and we expect this change could be up to twenty percent of our unrecognized tax benefits. On August 27, 2012, the United States Court of Appeals for the Third Circuit overturned a prior Tax Court decision and ruled in favor of the IRS and adverse to the Historic Boardwalk Hall LLC, a partnership in which we had made an investment in the year 2000. The case has been sent back to the Tax Court for additional proceedings. Based on our entitlement to indemnification under the partnership agreement, we do not expect this matter to have a material effect on our results of operations.
