Income Taxes	4.Income Taxes Our effective tax rate increased to 44.8% from 43.2% for the three months ended June 30, 2015 and 2014, respectively, and increased to 43.6% from 42.6% for the six months ended June 30, 2015 and 2014, respectively, primarily due to changes in state apportionments and permanent differences. The principal differences between the statutory rate and our effective rate are state taxes and permanent differences. In April 2015, legislation was signed changing New York City tax law, which resulted in the Company recognizing approximately $0.6 million in discrete tax expense for both the three and six months ended June 30, 2015. This discrete item had an approximate effective tax rate impact of 6.0% and 3.7% for the three and six months ended June 30, 2015, respectively. During the six months ended June 30, 2015, we utilized $3.9 million in tax deductions arising from stock-based compensation, which resulted in an excess tax benefit of $1.5 million that was recorded to capital in excess of par value and an offsetting reduction to taxes payable. As of June 30, 2015 and 2014, the total amount of unrecognized tax benefits was approximately $1.4 million and $1.6 million, respectively (net of the federal benefit for state issues) that, if recognized, would favorably affect our future effective tax rate.
