Oregon Revised Statutes Insurance § 731.512

(1) No insurer shall withdraw from this state until its direct liability to its policyholders and obligees under all its insurance policies then in force in this state has been assumed by another authorized insurer under an agreement approved by the Director of the Department of Consumer and Business Services. In the case of a life insurer, its liability pursuant to policies issued in this state in settlement of proceeds under its policies shall likewise be so assumed.

(2) The director may waive this requirement if the director finds upon examination that a withdrawing insurer then is fully solvent and that the protection to be given its policyholders in this state will not be impaired by the waiver.

(3) The assuming insurer within a reasonable time shall replace the assumed insurance policies with its own, or by indorsement thereon acknowledge its liability thereunder.

(4) This section is in addition to the requirements of ORS 732.517 to 732.546 and 742.150 to 742.162.
