Cash Balance Termination

[Guest Tad77]

Two questions on a cash balance termination:

1) What are the rules for the payment of interest on cash balance accounts after the date of plan termination. My understanding is that so long as plan assets are distributed with no more than a reasonable administrative delay then no interest need be paid but is it permissible to pay interest after the date of plan termination until the date of distribution? Also, does this rule also apply to employee after-tax accounts within a cash balance plan?

2) Is it acceptable to calculate benefits as of the date of distribution rather than the date of plan termination (assuming the benefit payable at date of distribution exceeds the benefit calculated as of the date of plan termination)?
