MISO 401(k) Plan
What public Form 5500 filings show about the MISO 401(k) plan — and how to find and check your own account.
The MISO 401(k) on its latest Form 5500

Who runs the MISO 401(k)?
The plan’s recordkeeper — the firm that runs the website and statements where you check your balance, change contributions, and manage your account — is Fidelity, based on the plan’s Schedule C service-provider disclosure. That’s the login you use for your MISO 401(k).
Other service providers named on the filing (investment managers, trustees, auditors — not necessarily the recordkeeper): STRATEGIC ADVISORS.
How to check your MISO 401(k)
- Log in to Fidelity’s participant portal (the site on your statements).
- Ask MISO 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).
