Income Taxes
6.   Income Taxes
    Our effective tax rate decreased to 39.1% in the first two quarters of fiscal 2012 from 40.5% in the same period of fiscal 2011. The tax rates for both years were higher than our statutory tax rate primarily due to the write-off of deferred tax assets associated with equity compensation. In addition, the current period tax rate was lower than the prior period tax rate primarily due to a decrease in the amount of deferred tax asset write-offs related to equity compensation and to a lesser extent a decrease in the Canadian statutory rate.
