Lump sum distributions with AFTAP cert less than 60%

[ConnieStorer]

I have a Plan that keep waivering between 70% and less than 60% depending on the contributions deposited (or not deposited) by the plan sponsor.  Election Forms for a bifurcated lump sum were sent out to eligible terminated participants.  The participant signed and returned their election form a few days before the new AFTAP was certified below 60%.  Can we proceed with the payout on the basis that it was signed and received by the plan sponsor prior to the new certification?
