Note 6—Income Taxes

The effective tax rate was 15% and 26% for the three months ended June 30, 2016 and 2015, respectively, and the effective tax rate was 28% and 26% for the six months ended June 30, 2016 and 2015, respectively.  The change in rate for the three months ended June 30, 2016 was primarily due to a decrease in pre-tax income from domestic operations taxed at a high statutory rate.  The change for the six months ended June 30, 2016 was primarily due to the unfavorable impact of a change in state apportionment on the Company’s domestic deferred tax liabilities as a result of the acquisition of Citigroup AIS during the first quarter, partially offset by the benefit received from a decrease in pre-tax income from domestic operations taxed at a high statutory rate.
