Understanding Fiduciary Responsibilities

Step-by-step guide to understand your fiduciary options.

Are you prepared to accept personal liability for your retirement plan?

Every retirement plan has at least one fiduciary—someone who’s responsible for administrative, operational, and investment management. If these responsibilities aren’t carried out diligently and in the best interests of employees, the fiduciary is personally liable.

Many business owners aren’t investment experts, and they outsource aspects of their fiduciary responsibility.

Is partnering with a 401(k) fiduciary right for your company? Consider your options.

It’s Your Duty

A retirement plan isn’t a set-it-and-forget-it program. Acting in the best interest of plan participants means paying close attention to your duties as a 401(k) fiduciary and keeping up with administration, operations, and investment management, so that every employee gets the retirement plan they expect and deserve.

What is a Fiduciary

The fiduciary role is about taking responsibility for doing what’s right.

As a plan sponsor, your employees are counting on you to help them save for retirement. A 401(k) that charges excessive fund fees, is poorly run, or isn’t managed with employee interests at heart puts their savings at risk. And that puts you at risk.

A fiduciary is a person legally required to act in someone else’s best interest.

A fiduciary is held to a standard “stricter than the morals of the market place.”

If you make decisions for the company 401(k) plan, you are a fiduciary.

Understanding Fiduciary Risk

You have a duty to protect your plan and employees.

Fulfilling your obligations as a fiduciary under the Employee Retirement Income Security Act (ERISA) is no small task. Documents, meetings, oversight, investment options, plan assets, employee communications—falling short of your duties can have serious consequences for you, your employees, and your retirement plan.

A fiduciary partner can help you carry out each of these duties faithfully and avoid putting employees or the company at risk.

  • Ignorance is no defense in a court of law.
  • A fiduciary is personally liable to make good on plan losses due to an ERISA provision breach.
  • The Department of Labor may assess a civil penalty equal to 20% of the recovery amount.
  • Individuals may be fined up to $100,000 and jailed up to 10 years for ERISA violations.
  • Companies may face up to $500,000 in fines for ERISA violations.

Liability Can Be Costly

In 2024, the Department of Labor recovered more than $1.4 billion from business owners and other fiduciaries for violations. Failure to act solely in the best interest of the retirement plan (even if it was a mistake) can cost you tens of thousands of dollars in legal fees, settlement costs, and time wasted.

Compare Fiduciary Options

A fiduciary partner can help you manage risk and reduce your liability.

Not all retirement plan advisors are the same. Knowing your level of comfort with investment management decisions and the liability that comes with them can help you find the right partner for your 401(k).

Find Your Comfort Level

When evaluating your fiduciary needs, consider a few essential questions:

  • Do you want to work with someone who makes investment recommendations or decisions?
  • Do you want to take on full fiduciary responsibility, shared responsibility, or no responsibility?
  • How involved do you want to be (or are equipped to be) in plan-related investment decisions?

Frequently Asked Questions

Learn the difference between 3(21) and 3(38) fiduciary services for your 401(k) plan. Understand your responsibilities, reduce liability, and choose the right support for your business.

What’s a Fiduciary?

A fiduciary is someone who is legally responsible for making decisions in the best interest of others. In the case of a 401(k) plan, that means choosing and managing investments that help your employees grow their retirement savings.
Under a law called ERISA (Employee Retirement Income Security Act), you’re a fiduciary if you:

  • Make decisions about how the plan is run
  • Manage the plan’s money or investments
  • Give investment advice for a fee

Even if your job title doesn’t say “fiduciary,” your actions might make you one. And that means you could be personally responsible if something goes wrong.

What Is ERISA?

ERISA is a federal law that protects people in retirement and health plans. It sets rules for how plans should be managed and who’s responsible for what. Two key parts of ERISA are:

  • Section 3(21): Defines the term fiduciary
  • Section 3(38): Defines requirements of an investment manager

Are You Personally Liable?

If you’re a fiduciary, you are responsible for creating and maintaining a documented, prudent process to select, monitor, and update investments that are appropriate for the plan. If you fail to do this, you could be held personally responsible for losses. That’s why many companies choose to work with outside experts.

What Is a 3(21) Investment Advisor?

A 3(21) advisor helps you choose investments but doesn’t make final decisions. You stay in control and keep the legal responsibility. This means liability for selection, monitoring, and updating the plan’s investments would stay with you. This is a good option if you want expert advice but still want to call the shots.

What Is a 3(38) Investment Manager?

A 3(38) manager takes full control of the investment lineup. They choose, monitor, and update the funds for you. Your job is to pick a good manager and check in on their performance and fees. If your goal is to fully minimize your fiduciary liability, consider hiring a 3(38) investment manager.

What Should I Consider When Hiring a 3(21) or 3(38) Fiduciary?

Think about how much control you want and how much risk you’re willing to take. If you’re confident in managing investments, a 3(21) adviser might be enough. But if you’d rather hand off the responsibility, a 3(38) manager could be the safer bet.
Either way, you’re still responsible for picking the right partner and keeping an eye on their work.
