Minn. Stat. § 61A.15

§ Subdivision 1. Variable annuity. All annuity contracts on a variable basis issued in this state shall stipulate the expense, mortality, and investment-increment factors to be used in computing (1) in the case of individual contracts, the dollar amount of variable benefits or other contractual payments or values, and (2) in the case of group contracts, the dollar amount payable with respect to a unit of variable benefits purchased thereunder. All such contracts shall guarantee that expenses shall not affect such dollar amounts adversely. In computing the dollar amount of variable benefits or other contractual payments or values under an individual contract on a variable basis, (a) the annual net investment increment assumption shall not exceed five percent, except with the approval of the commissioner, and (b) to the extent that the level of benefits may be affected by 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 higher mortality rate at any age, or, if approved by the commissioner, from another table. The term "expense," as used in this section, may exclude some or all taxes as stipulated in the contracts and may also exclude any investment management fee which is subject to change with the approval by vote of the holders of such contracts.

§ Subd. 2. Variable life insurance. Any life insurance contract on a variable basis delivered or issued for delivery in this state shall stipulate the investment increment factor to be used in computing the dollar amount of variable benefits or other variable contractual payments or values thereunder and shall guarantee that expense and mortality results shall not adversely affect such dollar amounts.
