The effective tax rates for the three months ended June 30, 2017 and 2016 were 32.4% and 25.8%. The increase in the effective tax rate during the three months ended June 30, 2017 was primarily a result of a change in the geographic mix of our income in addition to a one time reduction in a permanent tax benefit. The effective tax rates for the nine months ended June 30, 2017 and 2016 were 29.7% and 28.6%. The increase in the effective tax rate during the nine months ended June 30, 2017 was primarily a result of a change in the geographic mix of our income in addition to a one time reduction in a permanent tax benefit. These unfavorable items for the nine months ended June 30, 2017 were partially offset by the tax benefit recognized on share-based compensation in 2017 and an increase in the reserve for unrecognized tax benefits that occurred in 2016 but did not repeat in 2017.
