If you had money in one of these plans

  1. Call Fidelity (fidelity.com), which runs the Bayer Corporation Savings and Retirement Plan. With your Social Security number and the plan name, it can tell you whether you still have a balance and, if not, where it went.
  2. Or call the plan administrator listed on the plan below ((314) 694-1000). That number was filed for 2025; ask for the benefits or retirement plan office.
  3. If your plan was merged, your account moved with it. Follow the link on the plan to the plan it went into, and contact that one.
  4. Still stuck? The Department of Labor's benefits advisers help for free: askebsa.dol.gov or 1-866-444-3272. Never pay anyone to find your own money.
