I have seen this happen to some of our clients as well. Often times the insurance agent doesn't understand the requirement for a fidelity bond which is 10% of the plan assets upto a max of 500k. They will sell them more than is necessary and will cover things outside the plan. You should ask how the bond is registered. Sometimes they cover the company against theft and it sometimes will also cover the plan. If it is registered in the name of the company and not the name of the plan, then you probably have a policy that is covering more than just the plan assets. If you want to see the motive of the Insurance agent, ask what the premium per year is on the bond. I bet the agent is making a pretty penny....As you probably know, a three year prepaid fidelity bond for a min. of 250k, usually runs around 100.00 a year. I bet your client is paying in the thousands per year....
Good luck.
