Okla. Stat. tit. 36, § 36-4030.8: Present value of paid-up annuity benefit available as

nonforfeiture option.

For contracts that do not provide cash surrender benefits, the

present value of any paid-up annuity benefit available as a

nonforfeiture option at any time prior to maturity shall not be less

than the present value of that portion of the maturity value of the

paid-up annuity benefit provided under the contract arising from

considerations paid prior to the time the contract is surrendered in

exchange for, or changed to, a deferred paid-up annuity, such

present value being calculated for the period prior to the maturity

date on the basis of the interest rate specified in the contract for

accumulating the net considerations to determine maturity value, and

increased by any existing additional amounts credited by the company

to the contract. For contracts that do not provide any death

benefits prior to the commencement of any annuity payments, present

values shall be calculated on the basis of such interest rate and

the mortality table specified in the contract for determining the

maturity value of the paid-up annuity benefit. However, in no event

shall the present value of a paid-up annuity benefit be less than

the minimum nonforfeiture amount at that time.
