RCW 48.30.250: Interlocking ownership, management.

(1) Any insurer may retain, invest in or acquire the whole or any part of the capital stock of any other insurer or insurers, or have a common management with any other insurer or insurers, unless such retention, investment, acquisition or common management is inconsistent with any other provision of this title, or unless by reason thereof the business of such insurers with the public is conducted in a manner which substantially lessens competition generally in the insurance business or tends to create a monopoly therein.

(2) Any person otherwise qualified may be a director of two or more insurers which are competitors, unless the effect thereof is to substantially lessen competition between insurers generally or tends to create a monopoly.

(3) If the commissioner finds, after a hearing thereon, that there is violation of this section he or she shall order all such persons and insurers to cease and desist from such violation within such time, or extension thereof, as may be specified in such order.
