1 Source: Lipper, based on a worldwide analysis of all of the known providers of funds in these categories. The analysis covered ETFs, ETNs and mutual funds by the number of funds and assets (as of 6/30/2009).All investing involves risk, including the possible loss of principal. ProShares entail certain risks, including the use of aggressive investment techniques (futures contracts, options, forward contracts, swap agreements and similar instruments), imperfect benchmark correlation, leverage and market-price variance risks, all of which can increase volatility and decrease performance. ProShares are non-diversified and narrowly focused investments, including single country funds, typically exhibit higher volatility. International investments may also involve risk from unfavorable fluctuation in currency values, differences in generally accepted accounting principles and economic or political instability. In emerging markets, all these risks are heightened and lower trading volumes may occur. Short ProShares should lose value when their market indexes rise. There is no guarantee that any ProShares ETF will achieve its investment objective. Many ProFunds employ leveraged investment techniques that magnify gains and losses, and result in greater volatility in value. The NAV values of these International ProShares are computed as of the close of the U.S. securities markets based upon the value of one or more U.S. exchange traded securities or instruments that reflect the values of the securities underlying the Index. Carefully consider the investment objectives, risks, charges and expenses of ProShares and ProFunds before investing. This and other information can be found in their summary and full prospectuses. Read them carefully before investing. For ProShares ETF prospectuses visit proshares.com. For ProFunds mutual fund prospectuses visit profunds.com.
