Amex Moves to Sell Card-Backed Securities: American Express Co., seeking new funding sources, said it has told federal regulators that it wants to sell charge-card receivables to investors. An initial filing with the SEC did not specify a date or an amount for such an offering, American Express spokeswoman Susan Miller said. Big banks and other issuers of credit cards commonly sell their consumers’ IOUs to investors as repackaged debt securities. But American Express up to now has not sold consumers’ debt-repayment promises to investors, instead choosing to raise funds through other means. The SEC filing, made by American Express Receivables Financing Corp., a unit of American Express Travel Related Services Co., covers only Amex’s consumer charge cards.
