INCOME TAXES

A reconciliation of the U.S. federal statutory income tax rate to our effective income tax rate is as follows:


	For the Three Months Ended March 31,
	2021		2020
U.S. federal statutory income tax rate	21.0	%	21.0	%
State income taxes	2.8	%	2.7	%
Excess tax benefits from stock-based compensation plans	-0.4	%	2.3	%
Other	0.1	%	-0.3	%
Effective income tax rate	23.5	%	25.7	%

Excess tax benefits from stock-based compensation plans

During the first quarter of each year, we receive a tax benefit upon the vesting of restricted stock and the conversion of restricted stock units to common stock based on the fair value of the shares. The amount by which this tax benefit exceeds the grant-date fair value that was recognized as stock-based compensation expense is referred to as an excess tax benefit. Excess tax benefits are recognized in provision (benefit) for income taxes and reduce (increase) our effective income tax rate. The impact of excess tax benefits on our effective income tax rate decreased in magnitude from 2020 to 2021 primarily due to a decrease in the number of restricted stock units that were converted to common stock during the first quarter of 2021 due to the timing of long-term stock award grants.

Other

Other items impacting our effective income tax rate primarily consist of non-deductible executive compensation expenses. The impact on our effective income tax rate decreased in magnitude from 2020 to 2021 primarily due to the increase in pre-tax income.
