INCOME TAXES

Our effective tax rate was 19 percent and 23 percent for the three-month periods ended March 31, 2020 and 2019, respectively. The decrease in the tax rate was primarily due to an additional $2 million income tax benefit on stock-based compensation and an additional $2 million state income tax benefit from a reduction in the liability for uncertain tax positions resulting from the expiration of statutes of limitation, recognized in the first quarter of 2020.
