INCOME TAXES
The quarterly provision for income taxes is calculated using an estimated annual effective income tax rate, adjusted for discrete items that occur during the reporting period. The effective tax rates for the three and six months ended April 30, 2015 were 40.0% and 25.8%, respectively, as compared to 42.4% for each of the three and six month periods ended April 30, 2014. The effective tax rate for the six months ended April 30, 2015 was lower than the rate for the six months ended April 30, 2014 primarily due to the retroactive reinstatement of the Work Opportunity Tax Credit for calendar year 2014, which resulted in additional credits of $4.8 million as well as state employment-based tax credits of $2.5 million.
