Charles Schwab Corp. has retired the remaining $47.3 million of secured bank debt that it incurred in the management buyback from BankAmerica Corp. last year, the company announced. The retirement of the debt represented the remaining balance of the $150-million bank loan that was to be repaid in semiannual installments through 1991. Schwab, the nation’s largest discount broker, said the prepayment of the bank debt was made without utilizing borrowings from a new line of credit.
