Many ProFunds routinely employ leveraged investment techniques that magnify gains and losses and result in greater volatility in value. Each leveraged or inverse ProFund seeks a return that is a multiple (e.g., 200%) of the return of an index or other benchmark (target) for a single day. Due to the compounding of daily returns, 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 prospectus.

All ProFunds are subject to active investor risk. There are no restrictions on the size and frequency of trades and no transaction fees. The frequent exchanges our policies permit can decrease performance, increase expenses and incur tax consequences. All ProFunds permit active investment strategies that can decrease performance and increase expenses. In addition, it is important to note that some ProFunds are not suitable for all investors, because of aggressive investment techniques many of the funds employ.
