DUNIWAY, Circuit Judge: The Federal Deposit Insurance Corporation (FDIC) appeals from a summary judgment in favor of Bank of America, N.T. & S.A., in an action by FDIC to recover moneys deposited with Bank of America by Banco Credito y Ahorro Ponceno, a Puerto Rican Bank (Banco Credito) which became insolvent. Bank of America offset its liability for the deposits against the unpaid balance owed to it on a $5,000,000 subordinated capital note issued by Banco Credito. The trial court upheld the setoff. We reverse.
