Oregon Revised Statutes Corporations and Partnerships § 62.235

(1) Unless the articles provide otherwise, a cooperative may recall membership stock upon termination of membership, acquire, exchange, redeem, and reissue its own shares or other evidences of equity. Consideration paid for shares of membership stock recalled by the cooperative shall be the par value thereof and accrued and unpaid dividends, if any, except that if such shares have no par value the consideration paid therefor shall be the consideration in dollars for which the shares were issued plus accrued and unpaid dividends. The cooperative may set off obligations to it of the holder of membership stock or other stock or other evidence of equity, including capital credits or accounts representing capital credits. The cooperative shall have a continuing perfected security interest in the evidence of equity, capital credits or accounts representing capital credits to secure payment of any indebtedness, whenever incurred, owed to the cooperative by the holder. Notwithstanding any other provision of law, the security interest shall take priority over all other perfected security interests. No such acquisition, recall or redemption of stock or other evidence of equity shall be made if the result thereof would be to bring the value of the remaining assets of the cooperative below the aggregate of its indebtedness. The articles may provide other limitations on the right of a cooperative to acquire, recall, exchange or redeem its shares or other evidences of equity.

(2) When shares are acquired, recalled, exchanged or redeemed by the cooperative, such shares shall be restored to the status of authorized but unissued shares.
