Section 97B.49 - Dormant accounts1. In the event that all, or any portion, of a retirement allowance, death benefit, or other distribution payable to a member or a member's designated beneficiary, heirs at law, or estate, remains unpaid solely by reason of the inability of the system to locate the appropriate payee, the amount payable shall not be forfeited but shall be treated as a dormant account after the time for making a claim has run.2. A dormant account shall revert to the retirement fund created in section 97B.7. A dormant account shall be non-interest-bearing, and except for keeping a record of such account, the system shall not maintain the account. A member who has a dormant account and returns to covered employment shall have their dormant account reactivated as of the quarter they return to covered employment. If the appropriate payee contacts the system after the amount payable is treated as a dormant account, the appropriate payee may claim such amounts by filing a withdrawal application provided by the system. The system shall have rulemaking authority to adopt rules necessary to implement this section in a just and equitable manner.3. The system shall ensure that the payment of a dormant account as provided in this section meets the requirements of section 401(a)(9) of the federal Internal Revenue Code.
