Idaho Code § 45-809
Any cooperative corporation, as defined by Idaho Code, which provides goods or services to any person, firm or corporation, may set off any equity interest owned by such person, firm or corporation in the cooperative as a means of collecting obligations owed to it for such goods or services. Equity shall include, but not be limited to, membership stock, capital credits, accounts representing capital credits, capital stock or patronage credits. The cooperative shall have a lien on and a continuing perfected security interest in such equity to secure payment of any indebtedness, whenever incurred, owed to the cooperative by the person, firm or corporation receiving goods or services. Such lien and continuing perfected security interest may be enforced by right of offset when it becomes due and payable under the articles or bylaws of the cooperative. The cooperative's right of offset shall not entitle the debtor to set off its obligations against equity interest it owns in the cooperative which are not yet an obligation of the cooperative payable under the article or bylaws of the cooperative.
