We're terminating our plan due to M&A. We stopped taking money 2 days before the last payroll, so contributions were withheld from paychecks and will need to be refunded during the next payroll runs. I'm not concerned about the weekly people, but for our semi-monthly and monthly payroll people, is there anything I should be concerned about as far as holding on to the contributions and accruing interest for half a month or a month? EE's will squawk, but I just want to confirm.
