The Company's effective tax rate was 21.0% and 23.4% for the three and six months ended June 30, 2019, respectively, compared to 24.3% and 24.6% three and six months ended June 30, 2018, respectively. The decrease in the Company's effective tax rate for the three months ended June 30, 2019 was primarily driven by the release of uncertain tax positions as a result of the completion of an IRS examination of the Company's 2016 consolidated U.S. federal income tax return, which resulted in no changes to the Company's previously filed return. The Company remains subject to U.S. federal examination for amended tax returns filed in 2016 and the tax years ending after December 31, 2016. For the six months ended June 30, 2019, the effective tax rate was impacted by approximately $2.6 million of executive severance costs incurred in the first quarter of 2019, as previously disclosed, a significant portion of which is not deductible for income tax purposes.
