What to do if you're in this plan
- Amphenol Corporation & Affiliated Companies put in about $2,033 per active participant, below the typical peer ($2,320). Any match is still an instant return, so contribute enough to get all of it.
- 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.
