The effective income tax rates for the total provision (benefit) for both the three and six months ended June 30, 2021 and 2020 are greater than the federal statutory rate, primarily due to the effect of state income taxes.

During the next 12 months, we do not expect ultimate resolution of any unrecognized tax benefit associated with domestic or international matters to have a material impact on our unrecognized tax benefit position.
