INCOME TAXES INCOME TAXES
Our provision for income taxes for the three months ended March 31, 2021 and 2020 reflected effective tax rates of 5.4% and 0.7%, respectively. The year-over-year increase in the effective tax rate was primarily due to the increased impact of losses including certain impairments in jurisdictions with a full valuation allowance, and a change in the forecasted earnings mix.
Our effective tax rate can fluctuate depending on our country mix of earnings, since our foreign earnings are generally subject to higher tax rates than in the United Kingdom.
