Section 743.272 - Computing benefits(1) A variable annuity policy shall specify the investment increment factors to be used in computing the dollar amount of variable benefits or other variable payments or values under the policy, and may guarantee that expense or mortality results or both will not adversely affect such dollar amounts. In the case of an individual variable annuity policy under which the expense or mortality results may adversely affect the dollar amount of benefits, the expense and mortality factors shall be correspondingly specified in the policy. "Expense" as used in this subsection may exclude some or all taxes, as specified in the policy.(2) In computing the dollar amount of variable benefits or other policy payments or values: (a) The annual net investment increment assumption shall not exceed five percent, except with the approval of the Director of the Department of Consumer and Business Services; and(b) To the extent that the level of benefits may be affected by future mortality results, the mortality factor shall be determined from the Annuity Mortality Table for 1949, Ultimate, or any modification of that table not having a lower life expectancy at any age or, if approved by the director, from another table.
