Daily Yields as of 05-17-2013

Figures quoted represent past performance, which is no guarantee of future results. Investment return, principal value and yields of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Performance shown below does not include sales charges (as applicable), which have the effect of reducing the fund's performance. Current performance may be lower or higher than the performance data quoted. Click View Performance at the top of each section for month-end performance information.

Investing in all mutual funds entails risk. Information about the risks of investing in a Fund is available in the Fund's prospectus.

An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Wells Fargo Advantage Money Market Funds seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in a money market fund.

The daily factor is the interest factor that generates the dividend on a daily basis.

The 7-day current yield is an annualized net yield that describes the annualized income earned over a 7-day period. The 30-day current yield is an annualized net yield that describes the annualized income earned over a 30-day period. The current yield calculations assume that the income earned on the principal is not reinvested in the fund. The 7-day effective yield is annualized net yield that describes the amount one is expected to earn over a 1-year period assuming that dividends are reinvested at the average rate of the last 7-days. The 30-day effective yield is an annualized yield that describes the amount that would be earned over a 1-year period if dividends were reinvested at the average rate of the last 30 days.

The formula used to calculate the SEC yield is described in detail in the Fund's prospectus and is designed to standardize the yield calculations so that all mutual fund companies with the same or similar portfolios quote a uniform yield figure for their non-money market advertisements. SEC yields include the actual amount of interest earned adjusted by any gain or loss realized due to the return of principal, less expenses, and the maximum offering price calculated on a 30-day month-end basis.
