Foreign currency exchange rates may fluctuate significantly over short periods of time and can be unpredictably affected by political developments or government intervention. The value of the Reference Currencies included in the FX Basket may be affected by several factors, including: monetary policies of central banks within the relevant foreign countries or markets; global or regional economic, political or financial events; inflation or interest rates of the relevant foreign countries and investor expectations concerning inflation or interest rates; and debt levels and trade deficits of the relevant foreign countries. Currency exchange rates are influenced by the factors identified above and may also be influenced by, among other things: changing supply and demand for a particular currency; monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment in a country or on investment by residents of a country in other countries); changes in balances of payments and trade; trade restrictions; and currency devaluations and revaluations. Also, governments from time to time intervene in the currency markets, and by regulation, in order to influence rates directly. These events and actions are unpredictable. The resulting volatility in the Reference Currency exchange rates relative to the USD could materially and adversely affect the value of the Shares. | 7.
