Okla. Stat. tit. 36, § 36-2119: Nonassessable policies, mutual insurers

A. While it maintains on deposit with the State Treasurer

through the Insurance Commissioner surplus funds in amount not less

than the paid-in capital required of a domestic stock insurer

transacting like kinds of insurance, a domestic mutual insurer may

extinguish the contingent liability of its members as to all

policies in force, and may omit provisions imposing contingent

liability in all its policies currently issued.

B. When such surplus funds have been so deposited and the

Commissioner has so ascertained, he shall issue to the insurer at

its request his certificate authorizing such extinguishment and

omission of contingent liability.

C. A foreign or alien mutual insurer may issue nonassessable

policies to its members in this state in accordance with its charter

and the laws of its domicile, provided the standards and

requirements of the laws of the state of such domicile with respect

to the issuance of nonassessable policies are substantially

equivalent to or higher than the legal requirements in Oklahoma.
