All ProFunds permit active investment strategies that can decrease performance and increase expenses.

Many of the ProFunds routinely employ leveraged investment techniques that magnify gains and losses and result in greater volatility in value.

Each of the UltraSector ProFunds invests in a single industry, therefore an UltraSector ProFund's share do not represent a complete investment program. As non-diversified and single industry funds, the value of its shares may fluctuate more than shares invested in a broader range of industries and companies.

Some ProFunds invest internationally, which involves increased risk and volatility.

ProFunds benchmarked to small-cap company indexes typically carry additional risks since smaller companies generally have a higher risk of failure.

The Rising Rates Opportunity and U.S. Government Plus ProFunds routinely employ leveraged investment techniques that magnify gains and losses and result in greater volatility in value and are subject to market risks, including movements in prevailing interest rates.

An investment in the Money Market ProFund is not insured by the Federal Deposit Insurance Corporation or any other government agency. Although this ProFund seeks to preserve the value of your investment at $1 per share, it is possible to lose money by investing in the ProFund.
