[1] | During the three months ended June 30, 2021, certain statutory income tax rate changes (primarily an increase in the U.K. rate from 19 percent to 25 percent effective in 2023) were enacted that resulted in the remeasurement of our deferred tax liabilities and related deferred income tax expense.
[2] | See “CARES Act” on page 122 for a discussion of significant changes in tax law in the U.S. that were enacted in 2020.
