Who runs the Long-Middendorf Corporation 401(k)?
Long-Middendorf Corporation’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 Long-Middendorf CorporationHR for the recordkeeper’s name and login.
