Expense Example [Heading] Example
Expense Example Narrative [Text Block]

This 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 assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. The example reflects the fee waiver described above through the expiration date of such fee waiver and total annual fund operating expenses thereafter. You may be required to pay brokerage commissions on your purchases and sales of Class F-2, F-3, 529-F-2, 529-F-3 or ABLE-F-2 shares of the fund, which are not reflected in the example.
