John Hancock Disciplined Value Mid Cap Fund (the fund)
Supplement dated 9-21-12 to the current Class R6 shares Prospectus

In the "Fund summary" section, the information under the headings "Fees and expenses" and "Expense example" is amended and restated by the following:

Fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder fees (%) (fees paid directly from your investment)	Class R6
Maximum front-end sales charge (load) on purchases as a % of purchase price	None
Maximum deferred sales charge (load) as a % of purchase or sale price, whichever is less	None

Annual fund operating expenses (%)
(expenses that you pay each year as a percentage of the value of your investment)	Class R6
Management fee		0.79
Other expenses		3.43
Total annual fund operating expenses		4.22
Contractual expense reimbursement1		-3.27
Total annual fund operating expenses after expense reimbursements		0.95

1 The adviser has contractually agreed to reduce its management fee or, if necessary, make payment to the fund to the extent necessary to maintain the fund's total operating expenses at 0.95% for Class R6 shares, excluding certain expenses such as taxes, brokerage commissions, interest, litigation and extraordinary expenses, underlying fund expenses and short dividend expense. The current expense limitation agreement will remain in effect through September 30, 2013, unless renewed by mutual agreement of the fund and the adviser based upon a determination that this is appropriate under the circumstances at the time.

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 at the end of the various time frames indicated. 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:

Expenses ($)	Class R6
1 Year		97
3 Years		982
5 Years		1,881
10 Years		4,190
