The calculation of our effective tax rate is as follows for the three months ended March 31, 2021 and 2020 (in thousands, except percentages):

Three Months Ended
March 31,
2021 2020
Income before income taxes $ 62,027  $ 71,368 
Income tax expense $ 11,975  $ 13,967 
Effective tax rate 19.3  % 19.6  %

The effective tax rates were lower than the U.S. federal statutory rate of 21% due primarily to statutory depletion allowed on mineral royalty income.
