Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 9: INCOME TAXES We file a consolidated federal income tax return in the United States (U.S.) with the Internal Revenue Service (IRS) and file tax returns in various state and foreign jurisdictions. Tax returns are typically examined and settled upon completion of the examination, with tax controversies settled either at the exam level or through the appeals process. The Company currently does not have a U.S. federal return under examination; however, our U.S. federal return for calendar 2013 and future returns for all subsequent periods are open to examination. Additionally, the Company is either currently under examination or open to examination in all U.S. states that impose a corporate income tax. We had gross unrecognized tax benefits of $96.6 million, $112.9 million and $86.3 million as of October 31, 2015 and 2014 and April 30, 2015, respectively. The gross unrecognized tax benefits increased $10.3 million and $1.4 million during the six months ended October 31, 2015 and 2014, respectively. The increase in unrecognized tax benefits during the six months ending October 31, 2015 is related to various current year federal and state tax positions offset by a law change enacted in the state of Missouri which resulted in a clarification of certain prior year state income tax positions allowing a reduction in certain prior year state income tax reserves. We believe it is reasonably possible that the balance of unrecognized tax benefits could decrease by approximately $14.5 million within the next twelve months. The anticipated decrease is due to the expiration of statutes of limitations and anticipated closure of various state matters currently under exam. The portion of unrecognized benefits expected to be cash settled within the next twelve months amounts to $8.5 million and is included in accrued income taxes on our consolidated balance sheet. The remaining liability for uncertain tax positions is classified as long-term and is included in deferred tax liabilities and reserves for uncertain tax positions on the consolidated balance sheet. Consistent with prior years, our pretax loss for the six months ended October 31, 2015 is expected to be offset by income in the fourth quarter due to the established pattern of seasonality in our primary business operations. As such, management has determined that it is more-likely-than-not that realization of tax benefits recorded in our financial statements will occur within our fiscal year. The amount of tax benefit recorded reflects management's estimate of the annual effective tax rate applied to the year-to-date loss from continuing operations. Certain discrete tax adjustments are also reflected in income tax expense for the periods presented. A discrete income tax benefit of $26.6 million was recorded in the six months ended October 31, 2015, compared to a discrete tax benefit of $12.1 million in the same period of the prior year. The discrete tax benefit recorded in the current fiscal year resulted primarily from a law change enacted in the state of Missouri which provides us the ability to reduce tax expense related to income from our two prior fiscal years that was included on timely filed state tax returns for calendar year 2014 and will be timely filed for the 2015 tax return. The prior fiscal year discrete tax benefit was due largely to tax reserves released resulting from the expiration of statutory limitation periods. Excluding discrete items, management's estimate of the annualized effective tax rate for the six months ended October 31, 2015 and 2014 was 37.5% and 37.8%, respectively. Our effective tax rate for continuing operations, including the effects of discrete income tax items was 43.7% and 41.0% for the six months ended October 31, 2015 and 2014, respectively. Due to the loss in both periods, a discrete tax benefit in either period increases the tax rate while an item of discrete tax expense decreases the tax rate. The impact of discrete tax items combined with the seasonal nature of our business can cause the effective tax rate through our second quarter to be significantly different than the rate for our full fiscal year.
