Supplemental disclosures of cash flow information (in millions):	2021		2020		2019
Interest paid	$	215.7	$	188.9	$	169.2
Income taxes paid, net		325.4		113.0		22.2

Income taxes paid in the table above were net of AMT credits and $(28.5) million in 2021 due to the CARES Act, $(20.0) million in 2020 due to similar temporary relief measures available globally, and $(63.6) million in 2019 for other U.S. federal refunds. The 2021 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 method changes also affected 2021 estimated tax payments. These payments would have been made in future periods, and do not represent additional taxes due.

The following is a reconciliation of our end of period cash, cash equivalents and restricted cash balances as presented in the consolidated statement of cash flows for the years ended December 31, 2021, 2020 and 2019 (in millions):

	December 31,
	2021		2020		2019
Cash and cash equivalents	$	402.6	$	664.6	$	604.8
Restricted cash		4,063.7		2,909.7		2,019.1
Total cash, cash equivalents and restricted cash	$	4,466.3	$	3,574.3	$	2,623.9

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) $65.7 million, $63.6 million and $59.4 million related to the plan in 2021, 2020 and 2019, respectively. Our board of directors has authorized a 5% employer match on eligible compensation to the 401(k) plan year and the possible use of common stock to fund our 2021 employer matching contributions, which is expected to be funded in February 2022.

In fourth quarter 2021, in our consolidated statement of cash flows, we reclassed the net funding of premium finance loans from cash flows from operating activities to cash flows from investing activities. This change was made as this better reflects the cash flows associated with these operations. In addition, within cash flows from operating activities, we reclassed the net change in deferred income taxes to provision for deferred income taxes. We made the applicable reclassifications to the prior-period amounts to conform to the current period presentation. The impact of these changes increased net cash provided by operating activities and increased net cash used by investing activities by $54.6 million in 2020 and $71.9 million in 2019. These reclassifications did not impact our previously reported net increase (decrease) in cash, cash equivalents and restricted cash.
