Red flags from the filing
Benefits not paid when due: the plan reported failing to pay some benefits on time.
Corrective distributions: the plan refunded $25,575 in contributions, which usually means it failed annual nondiscrimination testing.
What to do if you're in this plan
- Mantech International put in about $4,717 per active participant, more than the typical peer ($2,951). 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.
- 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.
