Pinnacle Notes brochure. About 700 people here who invested a total of $26 million in complex structured products look certain to lose all their money. The products - called Pinnacle Notes Series 9 and 10 - have been battered by the financial crisis and are likely to be wound up for little more than small change. US investment bank Morgan Stanley, which arranged the notes through its Asian unit, broke the bad news on its website yesterday. Investors were also notified through the financial institutions they bought the product from. The notes in question were sold solely in Singapore, through five distributors - brokers DMG & Partners, Kim Eng Securities, OCBC Securities and UOB Kay Hian and lender Hong Leong Finance.
