The 2023 income taxes paid amount was favorably impacted due to the reversal of tax method changes on filing of the 2022 tax return. In 2022, we elected to defer the utilization of 2021 and 2022 net operating losses in the U.K. causing additional cash tax payments of $28.4 million relating to 2021 and $49.0 million relating to 2022. Both the U.S. and U.K. payments would have been made in future periods, and do not represent additional taxes due. In 2021, income taxes paid in the table above were net of AMT credits and $(28.5) million in 2021 due to the CARES Act. Also in 2021, the income taxes paid amount was unfavorably impacted due to payment of the $20.0 million of 2020 tax-payment deferrals (as noted in the previous sentence) and also approximately $106.0 million of tax payments made in 2021 with regards to tax method changes filed with our 2020 tax returns in the fourth quarter of 2021. Those U.S. federal method changes also affected our 2022 and 2021 estimated tax payments made in 2022 and 2021.

The following is a reconciliation of our end of period cash, cash equivalents, restricted cash and fiduciary cash balances as presented in the consolidated statement of cash flows for the years ended December 31, 2023, 2022 and 2021 (in millions):

We have a qualified contributory savings and thrift 401(k) plan covering the majority of our domestic employees. For eligible employees who have met the plan’s age and service requirements to receive matching contributions, we historically have matched 100% of pre-tax and Roth elective deferrals up to a maximum of 5.0% of eligible compensation, subject to federal limits on plan contributions and not in excess of the maximum amount deductible for federal income tax purposes. Beginning in 2021, the amount matched by the company will be discretionary and annually determined by management. Employees must be employed and eligible for the plan on the last day of the plan year to receive a matching contribution, subject to certain exceptions enumerated in the plan document. Matching contributions are subject to a five-year graduated vesting schedule and can be funded in cash or company stock. We expensed (net of plan forfeitures) $86.0 million, $73.8 million and $65.7 million related to the plan in 2023, 2022 and 2021, respectively. During 2022, our board of directors authorized the 5.0% employer matching contributions on eligible compensation to the 401(k) plan for the 2022 plan year to be funded with our with our common stock, which was funded in February 2023. During 2023, our board of directors authorized the 5.0% employer matching contributions on eligible compensation to the 401(k) plan for the 2023 plan year to be funded with our common stock, which is expected to be funded in February 2024.
