If you're hoping for a comfortable retirement, you may want to check in on your 401(k) to make sure it's not underperforming.

Experts say the vast majority of employer-sponsored retirement accounts are underserving their investors. Many 401(k) accounts are either underperforming or overpriced. Just as alarming, a majority of 401(k) plans may have at least one type of red-flag infraction, which could lead to fines or penalties.

Concerned about your 401(k)? Here are the signs to watch out for, and the best ways to fix potential problems with your retirement account.

Ted Benna, the "father of the 401(k)," warned many employer-sponsored plans charge excessive fees. In fact, he told The New York Times the whole mutual fund industry has profited enormously from 401(k) plans.

Even small fee increases, which may seem innocuous, can add up over time. Benna explained that "over the life of an investment, it is a real hit -- it is gigantic."

Almost 8 in 10 corporate retirement plans with at least 100 employees are overpaying on 401(k) fees, according to research from the consulting firm Abernathy-Daley. Any company paying more than 0.3% is probably overpaying, the report suggested.

Unnecessarily high fees can make a big difference in the size of your retirement fund. The U.S. Department of Labor pointed out that even a 1% increase in 401(k) fees could reduce savings by 28% for participants who set aside money over the course of 35 years or more. That could mean the difference between a comfortable retirement and one that has you pinching pennies and scraping by.

A 401(k) fund can underperform for a number of reasons, including:

  • Market fluctuations

  • Loss of funds due to fraud or dishonesty

  • Insufficient investment choices

  • High fees

Of course, no 401(k) is immune to market fluctuations. However, consistent underperformance is usually due to a systemic problem, like poorly chosen investment options or a lack of diversification.

Abernathy-Daley estimated 43% of 401(k) plans in the U.S. have at least one severe violation in areas like fraud or dishonesty, insufficient fidelity bonds or a failure to offer qualified default investment alternatives. These factors could all impact your fund's performance, with your retirement savings taking a major hit.

Violations could also cost your company a significant amount of money, thanks to penalties and fines imposed by regulators.

A whopping 76% of American 401(k) plans are also plagued with at least one less serious violation, which could impact participants' finances. These relatively minor infractions include:

  • Failing to offer automatic enrollment

  • Failing to issue corrective distribution of excess contributions

  • Failing to disburse payments in a timely manner

So, what should investors do if they're concerned about their employer-sponsored retirement plan? Here are a few ideas:

If you have any concerns about your 401(k) plan or have noticed any of the red flags described above, then it's time to take action.

If possible, schedule a one-on-one meeting with your company's plan manager and explain your concerns. Request to see the fund's benchmarking analysis, a comparative assessment that can tell you how well your fund stacks up against other 401(k) plans.

The Department of Labor recommends benchmarking 401(k) plans at least every three years. The more frequently the benchmarking is done, though, the better.

If your company's fund manager hasn't performed a benchmark in at least three years, they're probably taking a hands-off approach. This could be a major factor causing the fund to underperform, and could hurt your retirement savings.

It's a good idea to take your concerns about your 401(k) to your company's human resources department. Make sure the company understands that 401(k) infractions could result in severe penalties and stiff fines. The threat of these penalties should be enough to motivate your company to address any problems with the way your 401(k) is being managed.
