| (1) | This input is based on an industry mortality table and a range does not provide a meaningful presentation. |
| (2) | If the applicable interest rate is equal to or less than the interest rate on the account, the fair market value is equal to the contract value. If the applicable interest rate is greater than the interest rate on the account, the fair market value is the contract value reduced by a percentage. This percentage is equal to the difference between the applicable interest rate and the interest rate on the account, multiplied by the number of years (including fractional parts of a year) until the maturity date. |
