Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our income tax provision for the second quarter of fiscal years 2016 and 2015 reflects our estimates of the effective tax rates expected to be applicable for the full fiscal years, adjusted for any discrete events which are recorded in the period they occur. The estimates are reevaluated each quarter based on our estimated tax expense for the full fiscal year. The decrease in our effective tax rate in the six months ended May 31, 2016 compared to the same period in the prior year is primarily due to the jurisdictional mix of profits as a result of the acquisition of Telerik, where substantial losses were incurred in Bulgaria in fiscal year 2015 and tax effected at a 10% statutory rate and other jurisdictions’ earnings, primarily in the United States, were taxed at higher rates. In addition, during the preparation of our condensed consolidated financial statements for the three months ended May 31, 2016, we identified an error in our prior year income tax provision whereby income tax expense was overstated for the year ended November 30, 2015 by $2.7 million related to our tax treatment of an intercompany gain. We determined that the error is not material to the prior year financial statements. We also concluded that recording an out-of-period correction would not be material and have therefore corrected this error by recording an out-of-period $2.7 million tax benefit in our interim financial statements for the periods ended May 31, 2016. The Internal Revenue Service is currently examining our U.S. Federal income tax returns for fiscal years 2013 and 2014. Our Federal income tax returns have been examined or are closed by statute for all years prior to fiscal year 2012, and we are no longer subject to audit for those periods. Our state income tax returns have been examined or are closed by statute for all years prior to fiscal year 2011, and we are no longer subject to audit for those periods. Tax authorities for certain non-U.S. jurisdictions are also examining returns, none of which are material to our consolidated balance sheets, cash flows or statements of income. With some exceptions, we are generally no longer subject to tax examinations in non-U.S. jurisdictions for years prior to fiscal year 2010.

Our income tax provision for the second quarter of fiscal years 2016 and 2015 reflects our estimates of the effective tax rates expected to be applicable for the full fiscal years, adjusted for any discrete events which are recorded in the period they occur. The estimates are reevaluated each quarter based on our estimated tax expense for the full fiscal year.

The decrease in our effective tax rate in the six months ended May 31, 2016 compared to the same period in the prior year is primarily due to the jurisdictional mix of profits as a result of the acquisition of Telerik, where substantial losses were incurred in Bulgaria in fiscal year 2015 and tax effected at a 10% statutory rate and other jurisdictions’ earnings, primarily in the United States, were taxed at higher rates.

In addition, during the preparation of our condensed consolidated financial statements for the three months ended May 31, 2016, we identified an error in our prior year income tax provision whereby income tax expense was overstated for the year ended November 30, 2015 by $2.7 million related to our tax treatment of an intercompany gain. We determined that the error is not material to the prior year financial statements. We also concluded that recording an out-of-period correction would not be material and have therefore corrected this error by recording an out-of-period $2.7 million tax benefit in our interim financial statements for the periods ended May 31, 2016.
