Michigan CLASS Investment Options

What is Michigan CLASS?

Michigan CLASS is a local government investment pool prioritizing safety, liquidity, convenience, and competitive yield. Since 1991, Michigan CLASS has strived to provide Michigan public agencies a safe and competitive investment alternative. Michigan CLASS invests only in instruments applicable to Michigan state laws governing investment options for local agencies. Michigan CLASS is established pursuant to a Participation Agreement (the Agreement) and is governed by a 13-member Board of Trustees elected by the program Participants (the Participants). 

Section 28 of Article 7 of the Michigan Constitution of 1963 provides, among other things, that the legislature may authorize two or more local governmental entities to enter into contractual agreements to provide for the joint administration of functions which each entity would have the power to perform independently and to share in the related costs and responsibilities with each other. In accordance with this constitutional provision and certain statutory provisions incorporated in the Urban Cooperation Act of 1967 of the State of Michigan, the Agreement constitutes an interlocal trust agreement creating a legal entity established for the purpose of facilitating the joint investment of public sector surplus funds. This type of program is included in Public Act 20 as amended in 1997, under Section 1 (1) h.

The program’s Investment Advisor is Public Trust Advisors, LLC, and the program’s Custodian is Fifth Third Bank.

Who Can Participate?

Participation in Michigan CLASS is available to any county, city, village, township, school district, authority, the state of Michigan, or any other political subdivision organized under the laws of the state of Michigan.

Michigan CLASS is not a bank. An investment in Michigan CLASS is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Michigan CLASS prime-style fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. Please review the Michigan CLASS Information Statement(s) located in the Document Center before investing. Many factors affect performance including changes in market conditions and interest rates and in response to other economic, political, or financial developments. Investment involves risk including the possible loss of principal. No assurance can be given that the performance objectives of a given strategy will be achieved. For risks associated with investing in both a prime-style and enhanced cash-style local government investment pool, please click here. Past performance is no guarantee of future results. Any financial and/or investment decision may incur losses.
