Michigan Compiled Laws, Chapter 487. Financial Institutions § 487.13801

Sec. 3801. (1) A bank, with the approval of shareholders owning 2/3 of the stock of the bank entitled to vote, may issue capital notes, debentures, and any other instrument of indebtedness, with or without warrants for preferred or common stock, convertible and nonconvertible, subordinated on insolvency, liquidation, or dissolution to all obligations except obligations to shareholders, in amounts and under terms and conditions approved by the commissioner on the basis of normal business considerations.

(2) In connection with the issuance of convertible capital notes, debentures, or any other instrument of indebtedness, the commissioner may grant approval for the bank to reserve a number of authorized and unissued shares of capital stock as shall be required for issuance in exchange for capital notes and debentures with respect to which conversion privileges exist. If capital notes, debentures, or any other instruments of indebtedness are converted into shares of common or preferred stock, a verified certificate executed by the president of the bank stating the amount of the conversion, and other information with respect to the conversion as the commissioner may require, shall be filed in the office of the commissioner.
