Income Taxes [Abstract] |
Income Taxes | (13) Income Taxes: We use an asset and liability approach for financial accounting and reporting of income taxes. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities and are measured by applying enacted tax rates and laws to the taxable years in which differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We recorded a future tax benefit of approximately $5.4 million resulting from a worthless stock deduction related to SWSS stock recognized during the three and six months ended October 31, 2012. At October 31, 2012, we had gross tax-affected unrecognized tax benefits of approximately $691,000, all of which, if recognized, would favorably impact our effective tax rate. Included in the unrecognized tax benefits at October 31, 2012 and 2011 was approximately $117,000 and $111,000, respectively, of accrued interest and penalties related to uncertain tax positions, which have been recorded in other non-current liabilities as none of these positions are expected to reverse in the next 12 months. The full value of our unrecognized tax benefits has been classified as non-current income tax liabilities because a payment of cash is not anticipated within one year of the balance sheet date. In fiscal 2013, we expect to incur additional interest on outstanding tax accounts. We do not expect this change to be material. Interest and penalties related to income tax liabilities are included in income tax expense. With limited exceptions, we are subject to U.S. federal, state, local, and non-U.S. income tax audits by tax authorities for fiscal years subsequent to April 30, 2008.
