[2] | The utilization of guaranteed withdrawals represents the percentage of contractholders that will begin withdrawing in any given year.
[3] | Market volatility is implied volatility of fund of funds and managed volatility funds.
[4] | The weighted average for the spread to U.S. Treasuries for corporate debt securities (private placements) is weighted based on the security’s market value as a percentage of the aggregate market value of the securities.
[5] | The weighted average annual default rates of asset backed securities is weighted based on the security’s market value as a percentage of the aggregate market value of the securities.
[6] | The weighted average surrender rate is weighted based on the benefit base of each contract and represents the average assumption in the current year including the effect of a dynamic surrender formula.
[7] | The weighted average utilization rate represents the average assumption for the current year, weighting each policy evenly. The calculation excludes policies that have already started taking withdrawals.
[8] | The weighted average market volatility represents the average volatility across all contracts, weighted by the size of the guaranteed benefit.
[9] | The weighted average discount rate represents the average discount rate across all contingent consideration liabilities, weighted based on the size of the contingent consideration liability.
