Mich. Comp. Laws § 450.4303

Sec. 303. (1) Distributions of cash or other assets of a limited liability company shall be allocated among the members and among classes of members in the manner provided in an operating agreement. If an operating agreement does not provide for an allocation, distributions shall be allocated as follows: (a) Prior to July 1, 1997, on the basis of the value, as stated in the records the limited liability company is required to keep under section 213 or as determined by any other reasonable method, of the contributions made by each member to the extent that the contributions have been received by the limited liability company and have not been returned. (b) On and after July 1, 1997, except as otherwise provided in subsection (2), in equal shares to all members. A membership interest held by 2 or more persons, whether as fiduciaries, members of a partnership, tenants in common, joint tenants, tenants by the entirety, or otherwise, is considered as held by 1 member for an allocation under this subdivision. (2) If a limited liability company in existence before July 1, 1997 allocated distributions on the basis of subsection (1)(a), the limited liability company shall continue to allocate distributions pursuant to subsection (1)(a) until the allocation is changed by an operating agreement.
