Who runs the MASK-ET Services LLC 401(k)?
MASK-ET Services LLC’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 MASK-ET Services LLCHR for the recordkeeper’s name and login.
How to check your MASK-ET Services LLC 401(k)
- Log in to the plan’s recordkeeper portal (the site on your statements).
- Ask MASK-ET Services LLC 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).
