Mich. Comp. Laws § 141.112: Bonds; discount; sale price; interest; competitive or negotiated sale; notice; publication.

Sec. 12.

Bonds issued under this act may be sold at a discount but may not be sold at a price that would make the interest cost on the money borrowed after deducting any premium or adding any discount exceed 10% per annum or the maximum rate permitted by the revised municipal finance act, 2001 PA 34, MCL 141.2101 to 141.2821, whichever is greater, and may bear a stated rate of interest or no rate of interest.

A public corporation may sell bonds at a competitive sale or a negotiated sale as determined in the authorizing ordinance. If a public corporation determines to sell a bond at a negotiated sale, the governing body shall expressly state the method and reasons for choosing a negotiated sale instead of a competitive sale in the resolution or ordinance authorizing the issuance or sale of the bonds.

Bonds sold at a competitive sale shall not be sold until notice by publication at least 7 days before the sale in a publication printed in the English language and circulated in this state that carries as a part of its regular service notices of the sale of municipal bonds.

A public corporation shall award a bond sold at a competitive sale to the bidder whose bid meets all specifications and requirements and results in the lowest interest cost to the public corporation, unless all bids are rejected.

A public corporation may accept bids for the purchase of a bond made in person, by mail, by facsimile, by electronic means, or by any other means authorized by the public corporation.
