Fees and expenses
This table describes the fees and expenses you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts on Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the John Hancock family of funds. More information about these and other discounts is available on pages 14 to 16 of the prospectus under “Sales charge reductions and waivers” or pages 78 to 81 of the fund’s statement of additional information under “Initial Sales Charge on Class A Shares.”

Expense example
This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
