A policy issued to an employer or to the trustees of a fund established by an employer, which employer or trustees shall be deemed the policyholder, to insure employees of the employer for the benefit of persons other than the employer shall be subject to the following requirements:
(1) The employees eligible for insurance under the policy shall be all of the employees of the employer or all of any class or classes thereof determined by conditions pertaining to their employment. The policy may provide that the term employees shall include the employees of one or more subsidiary corporations and the employees, individual proprietors, partners, and members of one or more affiliated corporations, proprietors, partnerships, or limited liability companies if the business of the employer and of such affiliated corporations, proprietors, partnerships, or limited liability companies is under common control through stock ownership or contract. The policy may provide that the term employees shall include the individual proprietor, partners, or members if the employer is an individual proprietor, partnership, or limited liability company. The policy may provide that the term employee shall include retired employees. No director of a corporate employer shall be eligible for insurance under the policy unless such person is otherwise eligible as a bona fide employee of the corporation by performing services other than the usual duties of a director. No individual proprietor, partner, or member shall be eligible for insurance under the policy unless he or she is actively engaged in and devotes a substantial part of his or her time to the conduct of the business of the proprietor, partnership, or limited liability company.
(2) The premium for the policy shall be paid by the policyholder, either wholly from the employer's funds or funds contributed by him or her, or partly from such funds and partly from funds contributed by the insured employees. No policy may be issued on which the entire premium is to be derived from funds contributed by the insured employees. A policy on which part of the premium is to be derived from funds contributed by the insured employees may be placed in force only if at least seventy-five percent of the then eligible employees, excluding any as to whom evidence of individual insurability is not satisfactory to the insurer, elect to make the required contributions. A policy on which no part of the premium is to be derived from funds contributed by the insured employees must insure all eligible employees or all except any as to whom evidence of individual insurability is not satisfactory to the insurer.
(3) The policy must cover at least five employees at date of issue.
(4) The amounts of insurance under the policy must be based upon some plan precluding individual selection either by the employees or by the employer or trustees.
