92.11R5. For the purposes of paragraph b of section 92.11R4, the actualized value of future payments and that of future premiums is computed using,(a) in the case where the interest rate used by the issuer for a period in order to fix the terms of the contract at the time of issue is lower than the rate used for that purpose for a subsequent period, the simple rate that, if it applied to each period, would yield the same terms; or
(b) in all other cases, the rates that the issuer used in order to fix the terms of the contract at the time of issue.
