6.	Income taxes

We record our interim provision for income taxes based on our estimated annual effective tax rate, as well as certain items discrete to the current period. The effective tax rates for the three and six month periods ended April 30, 2015 were 31.2% and 29.3%, respectively. The effective tax rate for both the three and six month periods ended April 30, 2014 was 30.5%.

On December 19, 2014, the Tax Increase Prevention Act of 2014 was enacted which retroactively reinstated the Federal Research and Development Tax Credit (Federal R&D Tax Credit) from January 1, 2014 to December 31, 2014 and extended certain other tax provisions. As a result, our income tax provision for the six months ended April 30, 2015 included a discrete tax benefit of $1,686 primarily related to 2014.
