My bank displays both the FDIC and DIF logos. What does membership in these organizations mean?

As a member of both the Federal Deposit Insurance Corporation (FDIC) and the Depositors Insurance Fund (DIF), your bank provides full insurance for its customers’ deposits and accrued interest without limit or exception. Each depositor is insured by the FDIC to at least $250,000. All deposits above the FDIC insurance amount are insured by the Depositors Insurance Fund (DIF).
