________________ (1)The submission dates for filing income tax returns for the Company’s U.S. and U.K. operating subsidiaries are after the submission date of this report. Accordingly, the final tax liabilities may differ from the estimated income tax expense included in this report and may result in prior year adjustments being reported. The prior period adjustments for the twelve months ended December 31, 2022 predominantly relate to the determination of the results of the branches of the U.K. operating subsidiaries. The prior period adjustments for the twelve months ended December 31, 2021 and 2020 predominantly relate to the determination of results in the U.K. (2)The 2022 valuation allowance movement includes nil relating to U.K deferred tax assets in U.K. operating subsidiaries, $4.8 million decrease relating to deferred tax assets in the branches of the U.K. and Bermuda operating subsidiaries, and $94.1 million decrease from U.S. operations. The decrease in valuation allowance relating to our U.S. operations is driven by a change in judgment about the recoverability of deferred tax assets in the U.S. operating subsidiaries. We have concluded that the deferred tax assets of our U.S. operating subsidiaries will more likely than not be fully utilized over time, and therefore the previously recognized valuation allowance in relation to U.S. operating subsidiaries has been reversed. (3)In 2022, the Company did not have any unrecognized tax benefits.
