Each Short or Ultra ProShares ETF and leveraged or inverse ProFund seeks a return that is a multiple or inverse multiple (e.g., -200%) of the return of an index or other benchmark (target) for a single day , before fees and expenses. Due to the compounding of daily returns, Short or Ultra ProShares’ and leveraged and inverse ProFunds’ returns over periods other than one day will likely differ in amount and possibly direction from the target return for the same period. Investors should monitor holdings consistent with their strategies, as frequently as daily. For more on correlation, leverage and other risks, please read the ProShares or ProFunds prospectus. 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). 2 Source: Bloomberg, based on average volume, flows and assets from 3/31/2009 to 3/31/2010. 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 typically exhibit higher volatility. Short ProShares should lose value when their market indexes rise. There is no guarantee that any ProShares ETF will achieve its investment objective. 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.
