We periodically update the key assumptions used in the calculation of amortization of deferred policy acquisition costs and deferred sales inducements retrospectively through an unlocking process when estimates of current or future gross profits/margins (including the impact of realized investment gains and losses) to be realized from a group of products are revised. In addition, we periodically update the assumptions used in determining the liability for lifetime income benefit riders. We review these assumptions quarterly and as a result of these reviews, we made updates to assumptions in 2022, 2021 and 2020. During 2022 and 2021, American Equity Life entered into reinsurance agreements which ceded in-force fixed index annuity product liabilities. As a result, there was a write-off of deferred acquisition costs and a reduction of the liability for lifetime income benefit riders associated with the blocks of in-force liabilities ceded under the agreements. See Note 8 - Reinsurance and Policy Provisions for further discussion of these reinsurance agreements. 2022 Assumption Updates The most significant assumption updates made in 2022 were to investment spread assumptions, including the net investment earned rate and crediting rate on policies, lapse rate and partial withdrawal assumptions, and lifetime income benefit rider utilization assumptions. We updated our assumption for investment spread for American Equity Life to remain steady at 2.60% through an eight-year reversion period. We increased our long-term net investment earned rate assumption by 40 basis points with an assumption of 4.25% in the near term increasing to 5.00% over the eight-year reversion period, and we increased our long-term crediting/discount rate assumption by 30 basis points with an assumption of 1.65% in the near term increasing to 2.40% over the eight-year reversion period. In addition, we adjusted the grading of the discount rate assumption in the embedded derivative calculation. This change results in an increase in expected future gross profits and therefore a slight increase in the deferred policy acquisition costs and deferred sales inducements balances. This also results in a decrease in the liability for lifetime income benefit riders due to a higher discount rate. We updated lapse rate and partial withdrawal assumptions based on actual historical experience. We refreshed lapse tables based on 5 years of lapse experience and implemented a 1% lapse floor. For policies with a lifetime income benefit rider that does not charge a fee, we increased the lapse rates. For policies with a lifetime income benefit rider that has been utilized, we decreased the lapse rates. We expanded our partial withdrawal assumptions to include scalars in our assumptions during the surrender charge period, shock period, and post-shock period. This resulted in partial withdrawals extending beyond the surrender charge period. The net impact of the lapse rate and partial withdrawal assumptions resulted in a decrease in expected future gross profits and a decrease in the deferred policy acquisition costs and deferred sales inducements balances. The net impact of these changes resulted in an increase in the liability for lifetime income benefit riders due to higher excess claims and lower gross profits. We updated our lifetime income benefit rider utilization assumption structure to capture policyholder characteristics at a more granular level. This resulted in an increase in the number of policies utilizing and increased the excess claims. The impact of this change results in an increase in the liability for lifetime income benefit riders and an increase in the deferred policy acquisition costs and deferred sales inducements balances. 2021 Assumption Updates The most significant assumption updates made in 2021 were to investment spread assumptions, including the net investment earned rate and crediting rate on policies, lifetime income benefit rider utilization assumptions, mortality assumptions, and lapse rate assumptions as discussed below. Due to the continued low interest rate environment, we updated our assumption for investment spread for American Equity Life to 2.25% in the near term and increasing to 2.50% over an eight-year reversion period and our assumption for crediting/discount rate to 1.55% increasing to 2.10% over an eight-year reversion period. Prior to these assumption updates, our long-term assumption for aggregate investment spread was at 2.60% at then end of an eight-year reversion period, with a near term crediting/discount rate of 1.60% increasing to 2.10% over an eight-year reversion period. The assumption change to decrease aggregate investment spread resulted in lower expected future gross profits as compared to previous estimates and a decrease in the balances of deferred policy acquisition costs and deferred sales inducements. We updated lapse rate and mortality assumptions based on historical experience. For certain annuity products without a lifetime income benefit rider, the lapse rate assumption was increased in more recent cohorts to reflect higher lapses on polices with a market value adjustment ("MVA") feature. For other annuity products with a lifetime income benefit rider, the population was bifurcated based on whether policies had utilized the rider. For those policies which had utilized the rider, the lapse rate assumption was decreased in later durations. The overall mortality assumption was lowered to reflect historical experience. The net impact of the updates to the lapse rate and mortality assumptions resulted in higher expected future gross profits as compared to previous estimates and an increase in the balances of deferred policy acquisition costs and deferred sales inducements. The net impact of the updates to lapse rate and mortality assumptions resulted in an increase in the liability for lifetime income benefit riders due to a greater amount of expected benefit payments in excess of account values. We updated the lifetime income benefit rider utilization assumption based on historical experience. The ultimate utilization assumption was lowered for policies with a fee rider and certain policies with a no-fee rider. In addition, the utilization assumption was changed to reflect seasonality with higher utilization rates during the first quarter of each year. The net impact of the updates to the utilization assumption resulted in a decrease in the liability for lifetime income benefit riders due to a lower amount of expected benefits payments due to lower expected utilization. The net impact of the updates to the utilization assumption resulted in higher expected future gross profits as compared to previous estimates and an increase in the balances of deferred policy acquisition costs and deferred sales inducements. 2020 Assumption Updates The most significant assumption updates made in 2020 were to investment spread assumptions, including the net investment earned rate and crediting rates on policies, as well as updates to lapse rate and partial withdrawal assumptions. Due to the economic and low interest rate environments, we updated our assumption for aggregate investment spread to 2.40% in the near-term increasing to 2.60% over an eight-year reversion period and our assumption for crediting/discount rate to 1.60% increasing to 2.10% over an eight-year reversion period. Prior to these assumption updates, our long-term assumption for aggregate investment spread was steady at 2.60%, with a near term crediting/discount rate of 1.90% increasing to 2.90% over a 20 year reversion period. The assumption update to decrease aggregate investment spread resulted in lower expected future gross profits as compared to previous estimates and a decrease in the balances of deferred policy acquisition costs and deferred sales inducements. The decrease in the crediting rate, which is used as the discount rate in the calculation of the liability for lifetime income benefit riders, resulted in an increase in the liability for lifetime income benefit riders. We updated lapse rate and partial withdrawal assumptions based on actual historical experience. For certain annuity products without a lifetime income benefit rider, lapse rate and partial withdrawal assumptions were increased while for certain annuity products with a lifetime income benefit rider, lapse rate and partial withdrawal assumptions were decreased. The net impact of the updates to lapse rate and partial withdrawal assumptions resulted in lower expected future gross profits as compared to previous estimates and a decrease in the balances of deferred policy acquisition costs and deferred sales inducements. The net impact of the updates to lapse rate and partial withdrawal assumptions resulted in an increase in the liability for lifetime income benefit riders due to a greater amount of expected benefit payments in excess of account values.
