Citicorp won a conditional OK to acquire Quotron.

The Federal Reserve Board approved Citicorp’s proposed $680-million bid but said the banking firm must drop Quotron System Inc.’s computer hardware assembly operation within two years if the takeover is successful. Quotron, a Los Angeles-based provider of financial information, has rejected the offer as inadequate, but Citicorp has hinted at a possible hostile tender offer. The Fed said the hardware assembly operation doesn’t fall within guidelines established for bank ownership under the Bank Holding Company Act.
