What to do if you're in this plan
- Interface Security Systems put in about $745 per active participant, more than the typical peer ($712). 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.
- Direct plan expenses (0.50% of assets) are well above similar-size plans (0.23%). Check your annual fee disclosure, choose low-cost index funds if you can, and think about whether savings beyond the match belong in an IRA.
- The plan auto-enrolls employees. Check your default contribution rate. Defaults are often lower than what it takes to get the full match.
- 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.
