Oregon Revised Statutes Insurance § 732.567

The Director of the Department of Consumer and Business Services shall presume that a person controls another person if the person, directly or indirectly, owns, controls, holds with the power to vote, or holds proxies representing, 10 percent or more of the voting securities of the other person. A person may rebut this presumption with a showing in the manner provided under ORS 732.568 that control does not exist in fact. The director may determine, after giving persons that have an interest in the director's determination notice and opportunity to be heard and after making specific findings of fact to support the determination, that control exists in fact, notwithstanding the absence of a presumption that control exists in fact.
