The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions. The Examples are based, for the first year, on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.
