What to do if you're in this plan
- Marsh & Mclennan Companies put in about $8,061 per active participant, more than the typical peer ($5,179). 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.
- The plan reported no administrative expenses paid from plan assets. The employer may pay them, or the costs may be built into fund fees. Check your 404(a)(5) fee disclosure for each fund's expense ratio.
- 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.
