Note 11. Income Taxes


The effective tax rate on consolidated pre-tax income was 33.3% for the three months ended July 31, 2016, and 31.7% for the three months ended July 31, 2015. The effective tax rate on consolidated pre-tax income was 32.6% for the six months ended July 31, 2016, and 32.4% for the six months ended July 31, 2015. The fluctuation in the effective tax rate primarily relates to the impact of noncontrolling interests.
