Net amount at risk (2)	$	299.8	$	415.5

(1) The weighted-average attained age is calculated at the contract level using the total contributions since inception and the age of the contractholders.

(2) The net amount at risk for our GMDB riders is defined as the current GMDB amount in excess of the current account balance. The net amount at risk for our GMWB riders is defined as the greater of the present value of the GMWB payments less the current account balance or zero. For contracts with both GMDB and GMWB riders, the net amount at risk is the greater of the GMDB or GMWB net amount at risk. Increases in the equity markets and decreases in interest rates resulted in a decrease in the net amount at risk in 2023. Decreases in the equity markets and increases in interest rates resulted in an increase in the net amount at risk in 2022.
