Example
The example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
