BACKGROUND
What an ERISA 3(16) plan administrator does
ERISA section 3(16)(A) defines the plan administrator: the person or entity named in the plan document, or the plan sponsor if no one is named. The plan administrator is a fiduciary and is responsible for running the plan day to day in line with the plan document and ERISA. Many sponsors keep this role. Others appoint an outside firm, often called a 3(16) administrator, to take on some or all of it under a written agreement.
The exact duties depend on the plan and the service agreement, but responsibilities commonly include:
- Preparing, signing and filing the annual Form 5500.
- Providing required participant disclosures and notices.
- Overseeing the timely deposit of participant contributions withheld from pay.
- Overseeing distribution and loan processing under the plan's terms.
- Keeping plan records that support the plan's operation and filings.
Across all of these, the common thread is documentation. When a regulator, auditor or participant asks a question, the administrator needs to show the steps taken and the decisions made.
