Citicorp May Need More Capital: The beleaguered New York banking giant may need as much as $800 million stemming from a change in accounting rules for mortgage securities that it has sold on Wall Street. Citicorp’s problem, first reported by the trade publication American Banker, stems from a Federal Reserve Board ruling requiring banks to treat pools of home mortgages sold to investors as if they were part of the bank’s balance sheet. Citicorp said it believes that it doesn’t have to count all of the securities in its capital computations and hopes to persuade federal regulators to take the same position.
