Statutes govern acquisitions and mergers of insurance companies. The director may issue an order under ORS 732.544 if an insurer fails to submit adequate information in accordance with ORS 732.539 or if prima facie or substantial evidence of the type described in subsection (3)(a) or (b) of this section exists to support the director’s determination that an acquisition may: substantially diminish competition in a line of insurance in this state; or tend to create a monopoly.
