Section 1091 - Internal capital account cooperatives(a) An internal capital account cooperative is a worker cooperative whose entire net book value is reflected in internal capital accounts, one for each member, and a collective account, and in which no persons other than members own capital stock. In an internal capital account cooperative, each member shall have one and only one vote in any matter requiring voting by stockholders.(b) An internal capital account cooperative shall credit the paid-in membership fee and additional paid-in capital of a member to the member's internal capital account, and shall also record the apportionment of retained net earnings or net losses to the members in accordance with patronage by appropriately crediting or debiting the internal capital accounts of members. The collective account in an internal capital account cooperative shall reflect any paid-in capital, net losses, and retained net earnings not allocated to individual members.(c) In an internal capital account cooperative, the balances in all the individual internal capital accounts and collective account, if any, shall be adjusted at the end of each accounting period so that the sum of the balances is equal to the net book value of the worker cooperative.
