Income Taxes	3 Months Ended
Jul. 31, 2015
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 calendar 2013 federal return and federal returns for all periods after this date remain 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 $76.5 million, $128.1 million and $86.3 million as of July 31, 2015 and 2014 and April 30, 2015, respectively. The gross unrecognized tax benefits decreased $9.8 million and increased $16.6 million during the three months ended July 31, 2015 and 2014, respectively. The decrease in unrecognized tax benefits during the three months ending July 31, 2015 is primarily related to a law change enacted in the state of Missouri which allowed the Company to release prior year income tax reserves. We believe it is reasonably possible that the balance of unrecognized tax benefits could decrease by approximately $15 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 $8.7 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 deferred tax liabilities and reserves for uncertain tax positions on the consolidated balance sheet. Consistent with prior years, our pretax loss for the three months ended July 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 $20.6 million was recorded in the three months ended July 31, 2015, compared to a discrete tax benefit of less than $100 thousand in the same period of the prior year. The discrete tax benefit recorded in the current period 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 will be included on timely filed state tax returns for calendar years 2014 and 2015. Excluding discrete items, management's estimate of the annualized effective tax rate for the three months ended July 31, 2015 and 2014 was 37.4% and 38.1%, respectively. Our effective tax rate for continuing operations, including the effects of discrete income tax items was 48.4% and 38.1% for the three months ended July 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 the discrete tax items combined with the seasonal nature of our business can cause the effective tax rate through our first quarter to be significantly different than the rate for our full fiscal year.
