Income Taxes

For the three months ended July 31, 2019 and 2018, our effective tax rates were 2.4% and 10.5%, respectively. During the three months ended July 31, 2019 as compared to the prior year period, our effective tax rate decreased primarily due to an increase in excess tax benefits related to equity compensation. We recognized such excess tax benefits in our provision for income taxes of $17.0 million and $9.3 million for the three months ended July 31, 2019 and 2018, respectively.

For the six months ended July 31, 2019 and 2018, our effective tax rates were 3.7% and 7.5%, respectively. During the six months ended July 31, 2019 as compared to the prior year period, our effective tax rate decreased primarily due to an increase in excess tax benefits related to equity compensation. We recognized such excess tax benefits in our provision for income taxes of $30.6 million and $19.0 million for the six months ended July 31, 2019 and 2018, respectively.
