Income Taxes	9 Months Ended
Income Taxes	Jan. 31, 2014
Income Tax Disclosure [Abstract]
Income Taxes	Note 13: Income Taxes During the three-month and nine-month period ended January 31, 2014, 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 we could decrease our unrecognized tax benefits by an additional $1.5, primarily as a result of expiring statute of limitations periods.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
