Income Tax Expense

There was no significant variation in the customary relationship between income tax expense and income before income tax expense for the three and six months ended June 30, 2022.

During the three months ended June 30, 2021, certain statutory income tax rate changes (primarily an increase in the United Kingdom (U.K.) rate from 19 percent to 25 percent effective in 2023) were enacted that resulted in the remeasurement of our deferred tax liabilities. We recognized deferred income tax expense of $64 million during the three and six months ended June 30, 2021, which represented the net increase in our deferred tax liabilities resulting from the changes in the income tax rates.

Tax Returns Under AuditWe expect to complete the appeals process for certain U.S. federal income tax audits within the next 12 months. We do not expect to have a significant change to our liability for unrecognized tax benefits upon the settlement of our ongoing audits, and we believe that the ultimate settlement of our audits will not be material to our financial condition, results of operations, and liquidity.
