Income Taxes

The effective tax rate for the three months ended September 30, 2017 and 2016 was 26.8% and 30.3%, respectively. The decrease in the effective tax rate is due to a tax benefit recognized from a foreign exchange loss to be realized on a distribution from a foreign subsidiary, the release of reserves for uncertain tax positions, and increased excess tax benefits on stock-based compensation. These decreases were partially offset by a lower benefit related to the usage of foreign tax credits in the three months ended September 30, 2017.
