Written notice of allocation.
(b) Written notice of allocation. The term written notice of allocation means any capital stock, revolving fund certificate, retain certificate, certificate of indebtedness, letter of advice, or other written notice, which discloses to the patron the stated dollar amount allocated to him on the books of the cooperative organization, and the portion thereof, if any, which constitutes a patronage dividend. Thus, a mere credit to the account of a patron on the books of the organization without disclosure to the patron, is not a written notice of allocation. A written notice of allocation may disclose to the patron the amount of the allocation which constitutes a patronage dividend either as a dollar amount or as a percentage of the stated dollar amount of the written notice of allocation.
