(a) An insurer may retain, invest in, or acquire the whole or a part of the capital stock of another insurer or insurers, or have a common management with another insurer or insurers, unless the retention, investment, acquisition, or common management is inconsistent with a provision of this title, or unless by reason thereof the business of the insurers with the public is conducted in a manner that substantially lessens competition generally in the insurance business or tends to create a monopoly.
(b) A person otherwise qualified may be director of two or more insurers that are competitors, unless the effect is to lessen substantially competition between insurers generally or tends materially to create a monopoly.
