Income Taxes The effective income tax rate for the three months ended June 30, 2019, was 26.6%, a decrease from 33.3% for the three months ended June 30, 2018, primarily due to current quarter excess tax benefits from stock compensation and a favorable reduction in non-deductible employee meals, partially offset by current quarter non-deductible reserves related to legal proceedings. The effective income tax rate for the six months ended June 30, 2019, was 24.5%, a decrease from 35.4% for the six months ended June 30, 2018, primarily due to current year excess tax benefits from stock compensation compared to prior year excess tax deficits from stock compensation and a favorable reduction in non-deductible employee meals, partially offset by non-deductible reserves related to legal proceedings.
