Mont. Code § 33-20-512
For any contract which provides, within the same contract by rider or supplemental contract provision, both annuity benefits and life insurance benefits that are in excess of the greater of cash surrender benefits or a return of the gross consideration paid with interest, the minimum nonforfeiture benefits shall be equal to the sum of the minimum nonforfeiture benefits for the annuity portion and the minimum nonforfeiture benefits, if any, for the life insurance portion computed as if each portion were a separate contract. Notwithstanding the provisions of 33-20-506 through 33-20-509 and 33-20-511, additional benefits payable in the event of total and permanent disability or as reversionary annuity or deferred reversionary annuity benefits or as other policy benefits additional to life insurance, endowment, and annuity benefits, and considerations for all such additional benefits shall be disregarded in ascertaining the minimum nonforfeiture amounts, paid-up annuity, cash surrender, and death benefits that may be required by this section. The inclusion of such additional benefits shall not be required in any paid-up benefits, unless such additional benefits separately would require minimum nonforfeiture amount paid-up annuity, cash surrender, and death benefits.
