The decrease in the effective tax rate for the three months ended March 31, 2022 when compared to the three months ended March 31, 2021, is primarily attributable to the state tax expense related to the geographical distribution of the pre-tax income.

The increase in the effective tax rate for the six months ended March 31, 2022 when compared to the six months ended March 31, 2021, is primarily attributable to the state tax expense related to state tax law changes that were recorded discretely in each of the periods.
