Income Taxes Income Taxes
We are part of a tax sharing and compensating agreement with respect to federal income taxes with ARL. In accordance with the agreement, our expense (benefit) in each year is calculated based on the amount of losses absorbed by taxable income multiplied by the maximum statutory tax rate of 21%.
The following table summarizes our income tax provision:

The 2020 and 2019 effective tax rate is driven primarily by the passing of the Tax Cuts and Jobs Act by congress on December 22, 2017.  This act reduced the statutory tax rate for corporations to 21%, starting in 2019. As a result, our tax assets were remeasured to reflect the new tax rate for future years with the impact on the 2018 provision for income taxes.
