Who runs the MESO Inc. 401(k)?
MESO Inc.’s Form 5500 doesn’t separately disclose a recordkeeper we can confirm. The firms named on its Schedule C are service providers — which can include investment managers, trustees, and auditors, and are not necessarily the company that runs your account. To find who runs your 401(k), check your enrollment paperwork or a recent statement, or ask MESO Inc.HR for the recordkeeper’s name and login.
How to check your MESO Inc. 401(k)
- Log in to the plan’s recordkeeper portal (the site on your statements).
- Ask MESO Inc. HR or benefits for the recordkeeper name and enrollment link.
- Left the company? Your balance stays in the plan until you roll it over — see how to find a lost 401(k).
