Which of the following is NOT an element used to determine the amount of a SPIA payment?

In determining the amount of a Single Premium Immediate Annuity (SPIA) payment, the key elements typically include the size of the initial premium, the payment period, and the interest rate.

The size of the initial premium is critical, as it directly influences the amount of the periodic payments. A larger initial premium generally results in larger payments. The payment period is also significant because it establishes how long the annuity will make payments to the annuitant, which affects the periodic payment size—shorter periods may yield higher payments and longer periods result in lower payments per period. The interest rate plays a crucial role as well, informing how much interest the insurer might earn on the premiums, which in turn affects the payment amounts.

In contrast, the bailout rate is not a standard factor in determining SPIA payments. The bailout rate usually pertains to other types of contracts or investments where a policyholder may exit with certain conditions or fees. It does not influence the actual calculation of the periodic payments an annuitant receives from a SPIA. Therefore, it is the element that is not used in determining the amount of a SPIA payment.
