Income Taxes	9 Months Ended
Jan. 31, 2017
Income Tax Disclosure [Abstract]
Income Taxes	NOTE 7: 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 income tax return under examination. Our U.S. federal returns for 2012 and prior periods have been audited by the IRS and are closed. Our U.S. federal returns for 2013 and after have not been audited and remain open to examination. With respect to state and local jurisdictions and countries outside the United States, we and our subsidiaries are typically subject to examination for three to six years after the income tax returns have been filed. Although the outcome of any audit is uncertain, we believe that adequate amounts of tax, interest and penalties have been provided for in the consolidated financial statements for any adjustments that might be incurred due to state, local or foreign audits. We had gross unrecognized tax benefits of $97.1 million, $75.2 million and $111.5 million as of January 31, 2017 and 2016 and April 30, 2016, respectively. The gross unrecognized tax benefits decreased $14.4 million and $11.0 million during the nine months ended January 31, 2017 and 2016, respectively. The decrease in unrecognized tax benefits during the nine months ending January 31, 2017 is primarily related to state audit settlements and the expiration of statutes of limitations in multiple states. We believe it is reasonably possible that the balance of unrecognized tax benefits could decrease by approximately $12.8 million within the next twelve months. The anticipated decrease is due to the expiration of statutes of limitations and anticipated closure of state matters currently under exam. The portion of unrecognized benefits expected to be cash settled within the next twelve months amounts to $7.7 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 other noncurrent liabilities in the consolidated balance sheet. Consistent with prior years, our pretax loss for the nine months ended January 31, 2017 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 at least 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 $8.9 million was recorded in the nine months ended January 31, 2017, compared to a discrete tax benefit of $36.2 million in the same period of the prior year. The discrete tax benefit recorded in the current period resulted primarily from settlements of state audits. The discrete tax benefit recorded in the prior year resulted primarily from a law change enacted in the state of Missouri. Our effective tax rate for continuing operations, including the effects of discrete income tax items was 37.2% and 44.4% for the nine months ended January 31, 2017 and 2016, respectively. Discrete items increased management's estimate of the annualized effective tax rate for the nine months ended January 31, 2017 and 2016 by 1.5% and 6.3%, 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 third quarter to be significantly different than the rate for our full fiscal year.
