Oregon Revised Statutes Insurance § 732.551

(1) Every authorized insurer that is a member of an insurance holding company system shall register with the Director of the Department of Consumer and Business Services as provided in this section. A foreign insurer need not register if the foreign insurer is subject to registration requirements and standards adopted by statute or rule in the jurisdiction of its domicile that are substantially similar to those contained in:

(2) An insurer that is subject to registration under this section shall register not later than 15 days after the date the insurer becomes subject to registration, and annually thereafter on or before April 30 for the previous calendar year, unless the director for good cause shown extends the time for registration, and then within such extended time. The director may require any authorized insurer that is a member of a holding company system and is not subject to registration under this section to furnish a copy of the registration statement, the summary required in ORS 732.552 or other information filed by the insurer with the insurance regulatory authority of its domiciliary jurisdiction.
