When the FDIC transfers accounts to a new bank, it requires the depositers to "claim" the accounts within 18 months. WAMU failed in Sept 08 -- 18 months ago. Chase has been mailing warnings to some customes with yet unclaimed accounts. If you have an old WAMU account that you haven't used since the takeover, you may find that it has disappeared (turned over to the FDIC) in the very near future. This may particularly affect people who opened the free checking or savings accounts that they haven't used since rates plummeted, people who have long term CDs, and people who have not bothered to notify Chase of address changes.
