NORDDEUTSCHE Landesbank, the largest commercial bank in northern Germany, was to start selling $250 million of three-year, fixed rate Dragon bonds during London trading hours yesterday, a Goldman Sachs Asia official confirmed. The bonds would be priced to yield from 19-21 basis points more than the comparable US Treasury security, the banker said, noting that the securities would be listed on the Hong Kong, London and Singapore stock exchanges. Other investment bankers who expect to underwrite some of the bonds said that although Goldman was calling the financing a 'Dragon' bond, and thereby implying the bonds would be targeted mainly to Asian investors outside Japan, the transaction was better described as a Eurobond. That the sale will kick off in London, and that the primary underwriter will be Goldman Sachs International, the investment bank's European headquarters, makes this more of a 'Euro bond with an Asian flavor' several banking sources said. The bond sale has been planned since February.
