SDCL § 58-15-43.3: Initial calculation of changes in benefits or premiums--Recalculation after change.

In the case of a policy which causes, on a basis guaranteed in the policy, unscheduled changes in benefits or premiums, or which provides an option for changes in benefits or premiums other than a change to a new policy, the adjusted premiums and present values shall initially be calculated on the assumption that future benefits and premiums do not change from those stipulated at the date of issue of the policy. At the time of any such change in the benefits or premiums, the future adjusted premiums, nonforfeiture net level premiums and present values shall be recalculated on the assumption that future benefits and premiums do not change from those stipulated by the policy immediately after the change.
