Income Taxes

 

The Company files income tax returns in the United States Federal jurisdiction, in a limited number of foreign jurisdictions, and in many state jurisdictions. With few exceptions, the Company is no longer subject to United States Federal, state, or foreign income tax examinations for years before 2016.

 

The Company recorded income tax expense at an estimated effective income tax rate of 26.1% and 23.9% for the three and six months ended June 30, 2021, respectively, and 26.7% and 28.8% for the three and six months ended June 30, 2020, respectively. The Company’s estimated effective income tax rate for the three months ended June 30, 2021 approximates the statutory rate, while the estimated effective income tax rate for the six months ended June 30, 2021 was primarily impacted by the tax windfalls recognized upon the vesting of equity awards in the first three months of 2021. The Company’s estimated effective income tax rate for the three months ended June 30, 2020 approximates the statutory rate, while the estimated effective income tax rate for the six months ended June 30, 2020 was primarily impacted by costs associated with the acquisition of Geneva that are expected to be non-deductible for tax purposes.
