Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At January 31, 2016 and July 31, 2015, total unrecognized tax benefits were $3,055,000 and $2,796,000, respectively, including interest of $84,000 and $68,000, respectively. At January 31, 2016 and July 31, 2015, $1,469,000 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 January 31, 2016 and July 31, 2015, the remaining unrecognized tax benefits of $1,586,000 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 January 31, 2016 and July 31, 2015, $2,339,000 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. This ASU requires that deferred tax assets and liabilities be classified as non-current in a statement of financial position. Adoption of this ASU resulted in a reclassification of our net deferred tax assets and liabilities to the net non-current deferred tax asset in our Condensed Consolidated Balance Sheet beginning as of October 31, 2015. No prior periods were retrospectively adjusted. In December 2015, we received notification from the Internal Revenue Service ("IRS") of its intent to audit our federal income tax return for fiscal 2014. Our federal income tax returns for fiscal 2012 and 2013 are also subject to potential future IRS audit. None of our state income tax returns prior to fiscal 2011 are subject to audit. Future tax assessments or settlements could have a material adverse effect on our consolidated results of operations and financial condition. Excluding the impact of the TCS acquisition and any discrete tax items, we expect our fiscal 2016 effective tax rate to approximate 33.5%. This rate reflects the retroactive, permanent extension of the federal research and experimentation credit from December 31, 2014.
