Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At April 30, 2016 and July 31, 2015, total unrecognized tax benefits were $8,811,000 and $2,796,000, respectively, including interest of $59,000 and $68,000, respectively. At April 30, 2016 and July 31, 2015, $3,262,000 and $1,573,000, respectively, of our unrecognized tax benefits were recorded as non-current income taxes payable in our Condensed Consolidated Balance Sheets. At April 30, 2016 and July 31, 2015, the remaining unrecognized tax benefits of $5,549,000 and $1,223,000, respectively, were presented as an offset to the associated non-current deferred tax asset in our Condensed Consolidated Balance Sheets. Of the total unrecognized tax benefits at April 30, 2016 and July 31, 2015, $7,974,000 and $2,138,000, respectively, net of the reversal of the federal benefit recognized as deferred tax assets relating to state reserves, excluding interest, would positively impact our effective tax rate, if recognized. Unrecognized tax benefits result from income tax positions taken or expected to be taken on our income tax returns for which a tax benefit has not been recorded in our condensed consolidated financial statements. Our policy is to recognize interest and penalties relating to uncertain tax positions in income tax expense. On August 1, 2015, we adopted FASB ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes” on a prospective basis. TCS adopted FASB ASU No. 2015-17 during 2015 on a prospective basis. This ASU requires that deferred tax assets and liabilities be classified as non-current in a statement of financial position. At April 30, 2016, this ASU resulted in a reclassification of our net deferred tax assets and liabilities to the net non-current deferred tax liability in our Condensed Consolidated Balance Sheet. No prior periods were retrospectively adjusted. During the quarter ended April 30, 2016, the Internal Revenue Service ("IRS") continued to audit our federal income tax return for fiscal 2014. Our federal income tax returns for fiscal 2013 and 2015 are also subject to potential future IRS audit. None of our state income tax returns prior to fiscal 2011 are subject to audit. TCS’s federal income tax returns for calendar year 2013 and 2014 are subject to potential future IRS audit. None of TCS’s state income tax returns prior to calendar year 2011 are subject to audit. In addition to income tax audits, TCS is subject to ongoing state and local tax audits by the Washington State Department of Revenue and the City of Seattle. Future tax assessments or settlements could have a material adverse effect on our consolidated results of operations and financial condition.
