The aim is for the investment to reflect the performance of the STOXX® Europe 600 Health Care Index (Index) which is designed to provide the performance of shares of leading health care companies in Western Europe. The Index includes companies involved in health care provision, medical equipment, medical supplies, biotechnology and pharmaceuticals. A company?s weighting in the Index depends on its relative size but the largest and second largest company cannot exceed 30% and 15% respectively of the Index at each quarterly review date. The Index is calculated on a total return net basis which means that all dividends and distributions by the companies are reinvested in the shares after tax. To achieve the aim, the Fund will invest in transferable securities and enter into financial contracts (derivatives) with one or more swap counterparties relating to the transferable securities and the Index, in order to obtain the return on the Index.
