Credit Suisse has developed a global nanotechnology index focusing on companies offering nanotechnology products. Based on the index, two structured products have also been launched to allow investors to participate in potential growth in this sector. The index universe encompasses five sectors: nano materials, nano information technology, nano healthcare, nano tools, and nano energy/others. It offers investors exposure to 25 stocks representative of the nanotechnology universe worldwide and is to be rebalanced every six months to select new market leaders in each sector and also makes it possible to react to various corporate activities such as IPOs and new nanotechnology initiatives from existing firms. A CPUPLUS allows investors to benefit from capital protection at maturity and at the same time to retain the opportunity to participate in the positive performance of the index. The amount repaid at maturity depends on the change in the index during the term of the CPUPLUS. This is assessed each quarter, with the three best quarterly performance values of the underlying being substituted by a value that has been defined in advance. A CertificatePLUS allows investors, at maturity, to participate 100 per cent in any positive performance. Investors are also repaid in full provided that, during the term, the index does not reach or exceed pre-defined barrier values. If it does so at least once during the term, the investors continue to participate fully in the positive performance of the index, but without minimum repayment.
