Income Taxes

Note 15: Income Taxes

Income tax expense increased $1.1 million in the three months ended July 31, 2012, resulting in an increase in the effective tax rate to 33.7 percent, compared to 33.2 percent in the first quarter of 2012.

During the three-month period ended July 31, 2012, the effective income tax rate varied from the U.S. statutory income tax rate primarily due to the domestic manufacturing deduction, partially offset by state income taxes.

Within the next 12 months, it is reasonably possible that the Company could decrease its unrecognized tax benefits by an additional $0.6 million, primarily as a result of expiring statute of limitations periods.
