Remaining Premium Deficiency Reserve to be Recognized	$	1,660.0	$	2,310.0	$	2,061.0

1The gross PDR decreased by $126.0 million due primarily to premium rate increase activity and underlying growth in the locked-in statutory reserve basis during 2022. The gross PDR increased by $687.0 million and $190.0 million during 2021 and 2020, respectively, due primarily to changes in the assumed reinvestment rate. The increase for 2020 was from the original $2,100.0 million reserve deficiency as of December 31, 2018.

- Definition

Tabular disclosure of how the entity's reporting under GAAP as of the balance sheet date differs from the results based on prescribed and permitted accounting practices of the state or country of domicile in which a relevant statutory filing is made, or differences in results based on the National Association of Insurance Commissioners (NAIC) prescribed practices, or a combination thereof. Describes the accounting practices used and the related monetary effect on statutory surplus, net income, and risk-based capital. If an insurance enterprise's risk-based capital would have triggered a regulatory event had it not used a permitted practice, that fact is disclosed in the financial statements. Permitted statutory accounting practices include practices not prescribed but allowed by the domiciliary state insurance department regulatory authority.
