Do you manage the money in the defined benefit plan?

No. We are not financial planners or advisors. We are third party administrators, and our job is to determine funding and monitor compliance.

You would presumably be the plan sponsor and trustee. Your job is to manage the plan investments. You may hire a financial advisor to do this for you or you might select a discount broker like Charles Schwab, Fidelity or Vanguard. Since our plans are IRS approved qualified plans, you can use any financial advisor you like.
