(a) In this section, the word “insurer” includes 2 or more affiliated insurers:

(1) Under common management; or

(2) Under common controlling ownership or under other common effective legal control and in fact engaged in joint or cooperative underwriting, investment management, marketing, servicing or administration of their business and affairs as insurers.

(b) An insurer or advisory organization may not:

(1) Monopolize or attempt to monopolize, or combine or conspire with any other person or persons, or monopolize the business of insurance of any kind, subdivision or class thereof;

(2) Agree with any other insurer or advisory organization to charge or adhere to any rate or rating plan other than the uniform experience rating plan or rating rule except as needed to comply with the requirements of § 2607 of this title;

(3) Make an agreement with any other insurer, advisory organization or other person to unreasonably restrain trade or substantially lessen competition in the business of insurance of any kind, subdivision or class; or

(4) Make any agreement with any other insurer or advisory organization to refuse to deal with any person in connection with the sale of insurance.

(c) The fact that 2 or more insurers, whether or not members or subscribers of a common advisory organization, use consistently or intermittently the same rules, rating plans, rating schedules, rating rules, policy forms, rate classifications, underwriting rules, surveys or inspections or similar materials is not sufficient in itself to support a finding that an agreement exists.

(d) An advisory organization or member or subscriber thereof may not interfere with the right of any insurer to make its rates independently of that advisory organization or to charge rates different from the rates made by that advisory organization.

(e) Except as required under § 2607 of this title, an advisory organization may not have or adopt any rule or exact any agreement or formulate or engage in any program which would require any member, subscriber or other insurer to:

(1) Utilize some or all of its services;

(2) Adhere to its rates, rating plan, rating systems or underwriting rules; or

(3) Prevent any insurer from acting independently.
