Okla. Stat. tit. 36, § 36-4030.7: Cash surrender benefits prior to maturity

For contracts that provide cash surrender benefits, the cash

surrender benefits available prior to maturity shall not be less

than the present value as of the date of surrender of that portion

of the maturity value of the paid-up annuity benefit that would be

provided under the contract at maturity arising from considerations

paid prior to the time of cash surrender reduced by the amount

appropriate to reflect any prior withdrawals from or partial

surrenders of the contract, such present value being calculated on

the basis of an interest rate not more than one percent (1%) higher

than the interest rate specified in the contract for accumulating

the net considerations to determine maturity value, decreased by the

amount of any indebtedness to the company on the contract, including

interest due and accrued, and increased by any existing additional

amounts credited by the company to the contract. In no event shall

any cash surrender benefit be less than the minimum nonforfeiture

amount at that time. The death benefit under such contracts shall

be at least equal to the cash surrender benefit.
