  - (1)
    - (i) A NAFI employee who completed a qualifying move from FERS under [§ 847.402(a)](/cfr/5/847.402.md?p=a) may, instead of the election provided by [§ 847.411](/cfr/5/847.411.md) (pertaining to elections of CSRS and FERS coverage), elect to remain subject to the current NAFI retirement system for all subsequent periods of service.

  - (2) An NAFI employee who has had a previous opportunity to elect retirement coverage under § [847.202(e)](/cfr/5/847.202.md?p=e) or [(f)](/cfr/5/847.202.md?p=f) is not excluded from making this election.
- (b) A survivor may make an election under [paragraph (a)](#a) of this section if the employee was otherwise eligible, but died before expiration of the time limit under [§ 847.304](/cfr/5/847.304.md).
