(2) (i) Except as provided in subparagraph (ii) of this paragraph, for purposes of paragraph (1) of this subsection, the valuation net premium for a policy or contract shall be calculated by the method used in calculating the reserve on the policy or contract using the minimum valuation standards of mortality and interest rate under §§ 5-304 and 5-306 of this subtitle.
