Mich. Comp. Laws § 450.1338

Sec. 338. (1) A corporation may issue fractions of shares and may do 1 of the following: (a) Issue certificates for fractions of shares that entitle the holders to exercise voting rights and to receive dividends and distributions in proportion to their fractional holdings. (b) Pay in cash the fair value of fractions of shares as of the time when those entitled to receive the fractions are determined. (c) Issue scrip in registered or bearer form over the manual or facsimile signature of an officer of the corporation or of its agent, exchangeable as provided in the scrip for full shares. The scrip shall not entitle the holder to any right of a shareholder except as provided in the scrip. The scrip shall be issued subject to the condition that it becomes void if not exchanged for certificates representing full shares before a specified date. The scrip may be subject to the condition that the shares for which the scrip is exchangeable may be sold by the corporation and the proceeds of the sale distributed to the holders of the scrip, or subject to any other condition that the board may determine. (2) A corporation may provide reasonable opportunity for persons entitled to fractions of a share or scrip to sell them or to purchase additional fractions of a share or scrip needed to acquire a full share.
