Subd. 1. Refund or deferred annuity.
Subd. 2. Refund with interest.
Except as provided in subdivision 1, any person who ceases to be a public employee shall receive a refund in an amount equal to accumulated deductions with interest to the first day of the month in which the refund is processed at the rate of six percent compounded annually based on fiscal year balances. If a person repays a refund and subsequently applies for another refund, the repayment amount, including interest, is added to the fiscal year balance in which the repayment was made.
Subd. 3. Deferred annuity; eligibility; computation.
A member with at least three years of allowable service when termination of public service or termination of membership occurs has the option of leaving the accumulated deductions in the fund and being entitled to a deferred retirement annuity commencing at normal retirement age or to a deferred early retirement annuity under section 353.30, subdivision 1, 1a, 1b, 1c, or 5. The deferred annuity must be computed under section 353.29, subdivisions 2 and 3, on the basis of the law in effect on the date of termination of public service or termination of membership and must be augmented as provided in section 353.71, subdivision 2. A former member qualified to apply for a deferred retirement annuity may revoke this option at any time before the commencement of deferred annuity payments by making application for a refund. The person is entitled to a refund of accumulated member contributions within 30 days following date of receipt of the application by the executive director.
