Oregon Revised Statutes Corporations and Partnerships § 63.185

(a) Profits and losses that would have been realized on the date of admission of the additional member if all the assets of the limited liability company were then sold at their fair value shall be allocated among only the members of the limited liability company who are members immediately prior to the new member's admission based on the respective shares of profits and losses of such preexisting members before such admission. Thereafter the amount of profits or losses so allocated shall be treated as an adjustment to the contributions made by the preexisting members to the limited liability company; except that if the provisions of this subsection have been applied previously by the limited liability company in connection with the admission of a new member, the profits and losses allocated pursuant to this subsection shall be only those profits and losses realized since the most recent admittance of a new member; and

(b) Profits and losses realized by the limited liability company subsequent to the date of admission of the additional member shall be allocated among all the members, including the additional member, based on the respective shares of profits and losses of all the members after such admission.
