Finding that the hoped-for synergy that would see the numbers funnelled straight into its spreadsheet programs never materialised, Lotus Development Corp has thought better of its diversification into share price delivery systems and agreed to sell the Signal and QuoTrek services to Financial News Network. Financial News is 45%-owned by Infotechnology Corp, the New York-based parent of United Press International and other electronic publishing ventures. Terms of the sale were not disclosed, but analysts have valued the business at about $10m. Lotus’s One Source service, which sells electronic libraries of current, computer-readable data on businesses to professional investors, is not part of the sale: main users of the services being sold are small investors.
