A participant may elect on the form the Board of Trustees requires to have all or any part of an eligible rollover distribution paid to an eligible retirement plan in a direct rollover. If an eligible rollover distribution is payable to the designated spouse beneficiary of a member, former member, or retiree, the designated spouse beneficiary may elect to have all or any part of the eligible rollover distribution paid to an eligible retirement plan in a direct rollover. A nonspouse designated beneficiary may roll over an eligible rollover distribution only to a traditional or Roth individual retirement account or individual retirement annuity established for the purpose of receiving the distribution. A traditional or Roth individual retirement account or individual retirement annuity established under this paragraph shall be treated as an inherited individual retirement account or annuity within the meaning of § 408(d)(3)(C) of the Internal Revenue Code. A member who is eligible to participate in the plan administered by the supplemental plan under Title 35, Subtitle 5 of this article may elect to have all or any part of the eligible rollover distribution paid in a direct rollover to the plan in accordance with the regulations adopted by the supplemental plan.
