Retirement Plan Sponsors

Fiduciary guidance for 401(k), 403(b), defined benefit and cash balance plan sponsors and committees.

How Vistamark helps: Retirement Plan Sponsors →

Members of a retirement plan committee are ERISA fiduciaries, and the duty is personal: act solely in the interest of participants, follow a prudent process, and keep plan costs reasonable. Most claims against plan sponsors focus on process rather than results: fees that were never benchmarked, decisions that were never documented, and an investment lineup nobody reviewed against the plan’s investment policy statement.

These guides are written for the people who sit on 401(k), 403(b), defined benefit and cash balance plan committees: HR and finance leaders, executives, and the trustees of plans sponsored by nonprofits and professional firms. Each one turns a fiduciary duty into the documents and meeting habits that demonstrate it.
