Red flags from the filing
Late deposits: the filing says some employee contributions were not sent to the plan on time ($48,301 reported). That's money taken from paychecks that sat with the employer longer than the law allows.
Corrective distributions: the plan refunded $10,135 in contributions, which usually means it failed annual nondiscrimination testing.
What to do if you're in this plan
- STS Operating put in about $1,943 per active participant, more than the typical peer ($1,792). Contribute at least enough to collect the full match. Skipping it leaves part of your pay on the table.
- The filing shows total dollars, not the match formula. Ask HR for the Summary Plan Description so you know the exact match and vesting schedule.
- Fund expense ratios aren't in the filing. Look them up in your 404(a)(5) fee disclosure and favor low-cost index or target-date funds.
- The plan auto-enrolls employees. Check your default contribution rate. Defaults are often lower than what it takes to get the full match.
- The plan reported late deposits of employee contributions. Compare your pay stubs with your account statements, and contact the plan administrator if money shows up late.
- Changing jobs? You can usually leave the money in the plan, move it to your new employer's plan, or roll it into an IRA. Don't cash out: you'd owe taxes and possibly a 10% penalty.
