For top heavy account balance determination in a DC plan, are unvested amounts that are forfeited included when adding back distributions for participants who terminated during the year? For example, a participant with a total account balance of $10K, of which $9K is vested, terminates during 2017 and takes a distribution during 2017. Would you add back $10K or $9K? EOB gives an example that says, "the former employee's account balance must be included in the top heavy ratio" [my emphasis added]. I can't seem to find anything definitive in the Regs., but logically, it seems like you would add back what would have been the full value of the account (unvested portion included) since that's the amount you would include for someone who wasn't terminated.
