Income Taxes

3 Months Ended

Jul. 31, 2015

During the three-month period ended July 31, 2015, the effective income tax rate varied from the U.S. statutory income tax rate mainly due to state income taxes, offset to some extent by the domestic manufacturing deduction.

Within the next 12 months, it is reasonably possible that we could decrease our unrecognized tax benefits by an additional $2.1, primarily as a result of expiring statute of limitations periods.
