The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when sold or redeemed, may be worth more or less than the original cost. Shares are bought and sold at market price (not NAV) and are not individually redeemed from the fund. Market price returns are based upon the midpoint of the bid/ask spread at 4:00 p.m. ET (when NAV is normally determined for most funds) and do not represent the returns you would receive if you traded shares at other times. Your brokerage commissions will reduce returns. Current performance may be lower or higher than the performance quoted. For standardized returns and performance data current to the most recent month end, see above.

About the Index

The Bloomberg Commodity Balanced WTI Crude Oil Excess Return Index (ticker: BCBCLI Index) aims to track the performance of 3 separate contract schedules for WTI Crude Oil futures. One third of the index follows a monthly roll schedule, the second third of the index follows a June annual roll schedule, while the remaining third follows a December annual roll schedule.

The Index weights are equally reset semi-annually in the months of March and September on close of the first Business Day. To maintain the long position of the basket, contracts are 'rolled' from the expiring futures contract to a new contract farther down the futures curve with a longer expiry date. All commodities will roll on the second and the third Business Day of each calendar month.

*Schedule K-1 is the tax reporting form issued by commodities partnerships; the form typically presents additional complexities, including tax filing delays, versus the 1099 Form issued by an ETF registered under the Investment Company Act of 1940. NAV is typically set once a day when underlying securities markets close. Market prices change throughout the trading day. Returns here are based on composite closing prices and do not represent returns at other trading times. The first trading date is typically several days after fund inception, so NAV is used to calculate market returns prior to the first trade date. NAV total returns for the fund are used to calculate Growth of $10,000.

The expense ratio for certain funds includes a contractual fee waiver that results in a lower net expense ratio for some or all periods shown. For information about this ETF’s fees, please see above.

Investing involves risk, including the possible loss of principal. ProShares ETFs are generally non-diversified and each entails certain risks, including risks associated with the use of derivatives (swap agreements, futures contracts and similar instruments), leverage and market price variance, all of which can increase volatility and decrease performance. Please see their summary and full prospectuses for a more complete description of risks.

Investing in the energy industry is prone to significant volatility resulting from dramatic changes in commodities prices. There are additional risks related to large institutional purchases or sales, changes in exchange rates, government regulation, world events, economic and political conditions in the countries where energy companies are located or do business, and risks for environmental damage claims.

Certain derivative instruments will subject the fund to counterparty risk and credit risk, which could result in significant losses for the fund.
