The effective tax rates for the three months ended March 31, 2016 and 2015 were 31.1% and 31.4%. The decrease in the effective tax rate during the three months ended March 31, 2016 was primarily due to a favorable geographic mix of pre-tax income, partially offset by an increase in the reserve for unrecognized tax benefits. The effective tax rates for the six months ended March 31, 2016 and 2015 were 30.3% and 30.0%. The increase in the effective tax rate during the six months ended March 31, 2016 was primarily due to an increase in the reserve for unrecognized tax benefits, partially offset by a favorable geographic mix of pre-tax income.
