Maine Revised Statutes Title 5. Administrative Procedures and Services § 17156. Rate of interest

The board shall, from time to time, by order, set the rate of regular interest at a percent rate compounded periodically determined by the board to be equitable, both to members and to the taxpayers of the State, provided that the interest credited to a member with less than 10 years of creditable service on contributions related to compensation for service rendered as a part-time, seasonal or temporary employee after December 31, 1991 must at least equal the yield of a 10-year United States treasury bond on the last business day of the previous calendar year reduced by administrative expenses.
