The Fund aims to achieve a return on your investment, through a combination of capital growth and income on the Fund's assets, which reflects the return of S&P 500 GBP, the Fund's benchmark index (Index). The Index provides a return on the S&P 500 which measures the performance of the large-cap sector (i.e. leading companies with large market capitalisations) of the United States market. Market capitalisation is the share price multiplied by the number of shares issued. Companies are included in the Index based on a free float market capitalisation weighted basis. Free float means that only shares available to international investors, rather than all of a company's issued shares, are used to calculate the Index. Free float market capitalisation is the share price of a company multiplied by the number of shares available to international Investors. The Index also uses one month foreign exchange (FX) forward contracts to hedge each non-Sterling currency in the Index back to Sterling in accordance with the S&P Hedged Indices methodology. Hedging reduces the effect of fluctuations in the exchange rates between the currencies of the equity securities (e.g. shares) that make up the Index and Sterling, the base currency of the Fund.
