Our provision for income taxes was primarily due to taxes on international operations and state income taxes. The difference between the provision for income taxes that would be derived by applying the statutory rate to our loss before income taxes and the provision for income taxes recorded was primarily attributable to changes in our valuation allowance, non-deductible stock-based compensation expense and the tax rate differential between the U.S. and foreign countries.

As of October 31, 2017, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for the year ended January 31, 2017.
