The aim is for the investment to reflect the performance of the Deutsche Bank Liquid Commodity Index – Optimum Yield Balanced EUR (Index). The Index comprises financial contracts to buy commodities in the future at a particular price (known as futures). The commodities are: WTI Crude Oil, Brent Crude Oil, Heating Oil, RBOB Gasoline, Natural Gas, Gold, Silver, Aluminium, Zinc, Copper, Corn, Wheat, Soybeans and Sugar, each of which is given a specified weighting in the Index. The weighting of the commodities is rebalanced annually to return the Index to specified weightings. Deutsche Bank selects the futures according to “optimum yield” rules which seek to minimise potential losses and maximise potential gains which arise from replacing futures close to expiry with futures expiring at a later date. The effect of US Dollar-Euro exchange rate fluctuations is partially reduced in the Index.
