MainePERS administers all of our retirement plans in our members’ best financial interest. We follow Governmental Accounting Standards Board guidelines, and our actuaries follow all actuarial standards and best practices. We have choices within these guidelines and standards. All of our choices are made to keep our defined benefit plans well-funded while reducing the volatility of annual contributions. This volatility can result from financial market performance, changes in member demographics such as mortality, and other factors that affect plan funding. This section of our website provides the in-depth reports for each of our plans.
