(1) For investments over $1 million, a 1.00% maximum deferred sales charge may apply.

(2) Annual Fund Operating Expenses have been restated to reflect current fees and expenses.

(3) “Total annual fund operating expenses” do not correlate to the ratio of expenses to average net assets that is disclosed in the Fund’s annual report and semi-annual report in the financial highlights table, which reflects the operating expenses of the Fund and does not include Acquired Fund fees and expenses.

(4) Hartford Funds Management Company, LLC (the “Investment Manager”) has contractually agreed to reimburse expenses (exclusive of taxes, interest expenses, brokerage commissions and extraordinary expenses) to the extent necessary to maintain total annual fund operating expenses as follows: 1.50% (Class A), 2.25% (Class B), 2.25% (Class C), 1.25% (Class I), 1.70% (Class R3), 1.40% (Class R4) and 1.10% (Class R5). This contractual arrangement will remain in effect until February 28, 2017, and shall renew automatically for one-year terms thereafter unless the Investment Manager provides written notice of termination prior to the start of the next term or upon approval of the Board of Directors of The Hartford Mutual Funds, Inc. In addition, Hartford Administrative Services Company (“HASCO”), the Fund’s transfer agent, has contractually agreed to reimburse any portion of the transfer agency fees over 0.30% of the average daily net assets per fiscal year for all classes. This contractual arrangement will remain in effect until February 29, 2016, and shall renew automatically for one-year terms thereafter unless HASCO provides written notice of termination prior to the start of the next term or upon approval of the Board of Directors of The Hartford Mutual Funds, Inc.

EXAMPLE. The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

· Your investment has a 5% return each year

· The Fund’s operating expenses remain the same (except that the examples reflect the expense limitation arrangements for only the first year)

· You reinvest all dividends and distributions

· You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, for every $10,000 invested, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

Share Classes	Year 1		Year 3		Year 5		Year 10
A	$	686	$	972	$	1,279	$	2,148
B	$	728	$	1,014	$	1,426	$	2,409
C	$	318	$	673	$	1,154	$	2,483
I	$	113	$	353	$	612	$	1,352
R3	$	173	$	542	$	936	$	2,038
R4	$	143	$	449	$	779	$	1,711
R5	$	112	$	356	$	619	$	1,372

You would pay the following expenses if you did not redeem your shares:

Share Classes	Year 1		Year 3		Year 5		Year 10
A	$	686	$	972	$	1,279	$	2,148
B	$	228	$	714	$	1,226	$	2,409
C	$	218	$	673	$	1,154	$	2,483
I	$	113	$	353	$	612	$	1,352
R3	$	173	$	542	$	936	$	2,038
R4	$	143	$	449	$	779	$	1,711
R5	$	112	$	356	$	619	$	1,372
