We have several clients with DC plans that have terminated participants (with account balances less than $5k but more than $1k), which they would like to force these individuals out of their plans. We were thinking about creating a Group IRA Trust account to handle these balances and I was wondering if any other RIA/TPA firms have created a similar account for automatic rollovers? If so, what concerns or challenges have you faced?

There are a few commercial services to help you with this. Penchecks is one of the more helpful providers.
