Individuals, partnerships, and corporations of this state, referred to in this article as "subscribers", are authorized to exchange reciprocal or interinsurance contracts with each other, or with individuals, partnerships, and corporations of other states and countries, providing indemnity among themselves from any loss which may be insured against under other provisions of the law, excepting life insurance, if such subscribers, through their attorneys, attorneys-in-fact, agents, or other representatives, deposit and maintain on deposit with the commissioner moneys or securities of the value of fifty thousand dollars as security for the performance of all such contracts issued in this state or in any other state or country by such subscribers and as security for any act or omission by an attorney-in-fact required to be bonded for or secured against under any attorney-in-fact bond required by the laws of any state in which the reciprocal or interinsurance exchange does business. Such securities shall be such as are required for lawful investments of capital and reserve of domestic insurance companies by the provisions of sections 10-3-215 to 10-3-230. In lieu of such deposit or part thereof, the commissioner may accept a certificate of the public official having supervision over insurers in any other state to the effect that a like deposit by such insurer or a like part thereof in an equal or a greater amount is held in public custody in such state. The offices through which such indemnity is exchanged shall be classified as reciprocal or interinsurance exchanges.
