Income Taxes	R. INCOME TAXES Our effective tax rate was 37 and 5 percent for the three months ended March 31, 2015 and 2014, respectively. The 2015 tax rate includes certain anticipated non-deductible transaction costs related to the previously announced proposed spin-off of our Services Business. The 2014 tax rate includes the decrease in the valuation allowance resulting from the partial utilization of our U.S. Federal net operating loss carryforward. The effective tax rate was also impacted by a $3 million and $15 million state income tax benefit on uncertain tax positions primarily due to the expiration of applicable statutes of limitation for the three months ended March 31, 2015 and 2014, respectively. It is reasonably possible that the continued improvements in certain of our U.S. businesses could result in the objective positive evidence necessary to warrant the reversal of all or a portion of the valuation allowance on certain state and local deferred tax assets, up to approximately $27 million, by the end of 2015.
