Income Taxes [Abstract]
Income Taxes	16. Income Taxes Our effective income tax rate for the first nine months ended September 30, 2016 and 2015 was 30.5% and 31.3%, respectively. The rates varied from the statutory tax rate primarily due to the amount of tax exempt income in relation to total pre-tax income.
