Mich. Comp. Laws § 490.362
A credit union board may declare and pay a dividend on shares from current or accumulated net earnings, or both, but only after providing for required reserves, accrued and unpaid expenses, and established loan and lease losses. A domestic credit union may pay a dividend on partial or full shares and may pay the dividend at differing levels and at differing intervals based on the type of share accounts owned by a member, the liquidation priority of the share accounts, and the balances of the member's share accounts. A domestic credit union may determine the rate and amount of a dividend before the end of the dividend period involved. A domestic credit union shall not pay a dividend if payment would result in the insolvency of the domestic credit union.
