Expense Examples
The following examples illustrate the expenses you would have incurred on a
$10,000 investment in each Benchmark ProFund, and are intended to help you
compare the cost of investing in the Benchmark ProFunds compared to other mutual
funds. It assumes that you invested for the time periods shown and redeemed all
of your shares at the end of each period, that each ProFund earns an annual
return of 5% over the periods shown, that you reinvest all dividends and
distributions, and that gross operating expenses remain constant ( 1 year
examples for Bull and Bear ProFunds reflect current fee waivers). Because these
examples are hypothetical and for comparison only, your actual costs will be
different.
