Investing involves risk, including the possible loss of principal. ProShares are non-diversified and entail certain risks, including risk associated with the use of derivatives (swap agreements, futures contracts and similar instruments), imperfect benchmark correlation, leverage and market price variance, all of which can increase volatility and decrease performance. For more on correlation, leverage and other risks, please read the prospectus. There is no guarantee any ProShares ETF will achieve its investment objective.

Carefully consider the investment objectives, risks, charges and expenses of ProShares before investing. This and other information can be found in their summary and full prospectuses. Read them carefully before investing. A separate ProShares Trust II prospectus is available for Volatility, Currency and Commodity funds.
