Terminating Cash Balance Plan with Credit Balance on SB

So we taking over a Cash Balance Plan that's terminating and distributing the money to the participants (2 owners and 1 employee).  It's a non-PBGC Plan. 

The Plan is fully funded, and also has a credit balance displayed on the previous SB.

My questions is, how do we handle the Credit Balance on the final SB?  Is it still displayed, even if all of the money is distributed from the Plan?  Should the assets be distributed, with an excess given pro rate to the three participants?

I just want to understand what the process is so I can help out.

Thanks in advance!

In my 40+ years, I observed that IRS concerns approximate the following:

• First rule:  thou shalt follow thy plan's document and procedures.
• Second rule:  thou shalt not violate 415 limits.
• Everything else.

I'm not sure why you care about any credit balance.  It's also possible that you (ie, the plan sponsor) can just waive it.

The final SB is going to reflect the assets/measurement at some point in time before the payouts all took place, so if they happened to still have a PFB at the time, no big deal.
