Income Taxes	Income Taxes The effective income tax rate (provision for income taxes as a percentage of income from continuing operations before equity in earnings of affiliates and income taxes) was 45.3% and 40.5% for the three months ended March 31, 2013 and 2012, respectively. The difference between the effective tax rate for the quarter ended March 31, 2013 and the U.S. federal statutory rate of 35% is primarily attributable to a valuation allowance recorded against the capital loss carryforward generated from the sale of a controlling interest in a partnership. Income taxes included in equity in earnings of affiliates were $5.4 million and $6.0 million for the three months ended March 31, 2013 and 2012, respectively. For the purpose of segment reporting, these amounts are not reflected at the segment level but are recorded as a component of the corporate and eliminations group. It is reasonably possible that the amount of the unrecognized benefit with respect to certain unrecognized tax positions could significantly increase or decrease within the next 12 months. These changes may be the result of items such as ongoing audits, competent authority proceedings related to transfer pricing, or the expiration of federal and state statutes of limitation for the assessment of taxes.
