There is no guarantee that distributions will not be made in the future. There is no guarantee that dividends will be paid.

All investing involves risk, including the possible loss of principal. Short ProShares and ProFunds should lose value when their market indexes rise, and they entail certain risks, including, in some or all cases, aggressive investment techniques, inverse correlation and market price variance risks, all of which can increase volatility and decrease performance. ProShares and ProFunds are not diversified investments. Narrowly focused investments, including sector funds, typically exhibit higher volatility. ProShares and ProFunds are designed to meet daily objectives; results over longer periods may differ. There is no guarantee that any fund 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 prospectuses. Read the prospectus(es) carefully before investing. For a ProShares ETF prospectus, visit www.proshares.com and seek advice from your financial adviser or broker/dealer representative.

For a ProFunds mutual fund prospectus, call 888-PRO-FNDS (individual investors) or 888-PRO-5717 (financial professionals), or visit www.profunds.com. Read the prospectus(es) carefully before investing.
