| EXAMPLE: |
| |
| The price or value of a Zero Cert™ that tracks the RBS Thailand SET50® Index* will change according to any changes in performance in the underlying indexand/or the Forex Rate. |
| |
| *The Thailand SET 50 Index® is a capitalisation weighted index based on the top 50 stocks listed on the Stock Exchange of Thailand, with the highest capitalisation and liquidity. |
| |
| 8 June 2007 | | 8 August 2007 | | Underlying index = 532.16 | | Underlying Index = 595.22 | | FX Rate = THB/SGD 0.0475 | | FX Rate = THB/SGD 0.0495 |
|
| |
| Exercise amount = 23 |
| |
| Value of Zero Cert™ on 8 June 2007 | = | (532.16 x 0.0475) / 23 | | = | 1.10 |
|
| Market making (bid-offer spread) at 1.10/1.11 |
| |
| Value of Zero Cert™ on 8 August 2007 | = | (595.22. x 0.0495) / 23 | | = | 1.28 |
|
| Market making (bid-offer spread) at 1.28/1.29 |
| |
| Performance from 8 June – 8 August 2007 |
| |
| Index Performance | = | (595.22–532.16) / 532.16 = 11.9% |
|
| Currency Performance | = | (0.0495–0.0475) / 0.0475 = 4.2% |
|
| Zero Cert™ Performance | = | (1.29–1.11) / 1.11= 16.2% |
|
| |
| The investor’s return would therefore be roughly equivalent to the percentage gain/loss in the index level and the forex rates. |
