Evelyn, There could be a number of reasons why. However, in the absence of more information I would consider the following; The 401k may not yet have transferred[I had a case like that recently]/ You may only get quarterly statements from MU/. Try contacting your personnell benefits department and get more details. Good Luck, Dan
You might only get annual statements, but you should have gotten an initial statement. You should also be able to register to the online portal and view your account at any time.
Contact Human Resources and get the phone number of the plan administrator. They will be able to confirm your address, help you with your balance, and give you instructions to register on the online portal.
