The effective income tax rate for the total provision (benefit) for both the three months ended March 31, 2020 and 2019 is 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.
