What's entailed in maintaining a Cash Balance Plan and about how much time does the owner usually spend related to the plan in a year's time?

The owner usually spends less than ten hours a year on the plan. The maintenance responsibilities involve executing a plan document, distributing Summary Plan Descriptions to participants, enrolling new participants, keeping records on hours and pay, filing forms with the government (i.e. 5500 Forms), and processing participant termination payouts.
