State investment company Khazanah Nasional Bhd is gearing for more innovative investment options to follow its landmark portfolios in the sukuk marketplace. It plans to publish a coffee table book to share its success stories thus far. In recent weeks, Khazanah was in the news when it selected three banks to help arrange a sale of US$1 billion (RM2.98 billion) of convertible Islamic bonds. The Shar iah- compl iant bonds, or sukuk, would be exchangeable into shares of companies controlled by Khazanah. The company has launched innovative sukuk across Asia including the first global sukuk in US dollars, in Singapore dollars and in the yuan exchange. A rough estimate shows that Khazanah has helped raise US$3.5 billion for companies based in Singapore, Malaysia and Hong Kong, among others.
