The provision (benefit) for income taxes for the three and nine months ended March 31, 2017, included a benefit of $3,780 due to the reversal of the valuation allowance we previously had recorded against certain foreign deferred tax assets and also included a $1,442 benefit related to the exercise of employee stock options. Based on continued profitability in a foreign subsidiary, we concluded that it was more likely than not that the value of the related deferred tax assets would be realized, and it was no longer necessary to maintain a valuation allowance.

The provision (benefit) for income taxes for the three and nine months ended March 31, 2016, included a benefit of $2,536 and $21,323, respectively, due to the reversal of the valuation allowance we previously had recorded against domestic deferred tax assets. Based on continued domestic profitability, we concluded that it was more likely than not that the value of domestic deferred tax assets would be realized, and it was no longer necessary to maintain a valuation allowance.
