Your Expenses.   The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Hartford Funds. More information about these and other discounts is available from your financial professional and in the “Sales Charge Reductions and Waivers” section beginning on page [__] of the Fund’s statutory prospectus and the “Purchase and Redemption of Shares” section beginning on page [___] of the Fund’s statement of additional information.

Shareholder Fees   (fees paid directly from your investment)

Annual Fund Operating Expenses   (expenses that you pay each year as a percentage of the value of your investment)

(1)

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

​

(2)

Hartford Funds Management Company, LLC (the “Investment Manager”) has contractually agreed to reimburse expenses (exclusive of taxes, interest expenses, brokerage commissions, acquired fund fees and expenses and extraordinary expenses) to the extent necessary to maintain total annual fund operating expenses as follows: 1.29% (Class A), 1.04% (Class I), 1.40% (Class R3), 1.10% (Class R4), 0.80% (Class R5) and 0.75% (Class R6). 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. Each contractual arrangement will remain in effect until [February 28, 2017], and shall renew automatically for one-year terms thereafter unless the Investment Manager or HASCO, respectively, 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:

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

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was [___]% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY.   The Fund seeks to achieve its investment objective by investing primarily in stocks selected on the basis of potential for capital appreciation. The Fund normally invests at least 65% of its net assets in common stocks of medium and large companies. The Fund may invest up to 35% of its net assets in securities of foreign issuers and non-dollar securities, including companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The sub-adviser, Wellington Management Company LLP (“Wellington Management”), uses fundamental analysis to identify companies that it believes have substantial near-term capital appreciation potential regardless of company size or industry.

The Fund employs a multiple portfolio manager structure, which means the Fund has several components that are managed separately using different investment styles. Each component sleeve has a distinct investment philosophy and analytical process to identify specific securities for purchase or sale based on internal, proprietary research. Each component sleeve seeks growth of capital. Wellington Management does not allocate a set percentage to any specific sleeve but instead seeks a flexible and diversified Fund profile. Together the investment strategies represent a wide range of investment philosophies, companies, industries and market capitalizations. The Fund may trade portfolio securities actively.

PRINCIPAL RISKS.   The primary risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective. For more information regarding risks and investment matters please see “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.

4

Market Risk − Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to the activities and financial prospects of individual companies or to general market and economic movements and trends, including adverse changes to credit markets.

Investment Strategy Risk − The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. There is no guarantee that the Fund’s investment objective will be achieved.

Foreign Investments Risk − Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions, may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments.

Emerging Markets Risk − The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Asset Allocation Risk − The risk that if the Fund’s strategy for allocating assets among different asset classes and/or portfolio management teams does not work as intended, the Fund may not achieve its objective or may underperform other funds with similar investment strategies. The investment styles employed by the portfolio managers may not be complementary, which could adversely affect the performance of the Fund.

Equity Risk − The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Mid-Cap Securities Risk − The securities of mid cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies.

Active Trading Risk − Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

The Fund is subject to certain other risks, which are described elsewhere in the Fund’s statutory prospectus.

Principal Investment Strategy.   Under normal circumstances, the Fund invests at least 80% of its assets in common stocks. The Fund invests in a diversified portfolio of common stocks of issuers located primarily in the United States. Wellington Management Company LLP (“Wellington Management”), the Fund’s sub-adviser, chooses the Fund’s investments using fundamental research designed to identify issuers with improving quality metrics, business momentum and attractive relative valuations. The investment process is aided by a proprietary quantitative screening process that narrows the investment universe to companies that are consistent with the Fund’s investment strategy. The Fund’s portfolio is broadly diversified by industry and company. The Fund may invest in a broad range of market capitalizations, but tends to focus on large capitalization companies with market capitalizations similar to those of companies in the S&P 500 Index. The Fund may invest up to 20% of its net assets in securities of foreign issuers and non-dollar securities.

Quantitative Investing Risk − The value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance. This may be as a result of the factors used in building the quantitative analytical framework, the weights placed on each factor, the accuracy of historical data supplied by third parties, and changing sources of market returns.

Equity Risk − The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Foreign Investments Risk − Investments in foreign securities may be riskier than investments in U.S. securities.

During the most recent fiscal year, the Fund’s portfolio turnover rate was [___]% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY.   The Fund invests primarily in a portfolio of equity securities that typically have above average dividend yields and whose prospects for capital appreciation are considered favorable by the sub-adviser, Wellington Management Company LLP (“Wellington Management”). The Fund’s portfolio is broadly diversified by company and industry. Under normal market and economic conditions, at least 80% of the Fund’s net assets are invested in dividend paying equity securities. The Fund tends to focus on securities of larger, well-established companies with market capitalizations similar to those of companies in the S&P 500 Index. The Fund may invest up to 20% of its net assets in securities of foreign issuers and non-dollar securities. Wellington Management uses fundamental analysis to evaluate a security for purchase or sale by the Fund.

PRINCIPAL RISKS.   The primary risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective.

Market Risk − Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to the activities and financial prospects of individual companies or to general market and economic movements and trends, including adverse changes to credit markets.

Dividend Paying Security Investment Risk − Income provided by the Fund may be affected by changes in the dividend policies of the companies in which the Fund invests and the capital resources available for such payments at such companies. Issuers that have paid regular dividends or distributions to shareholders may not continue to do so at the same level or at all in the future. Dividend paying securities can fall out of favor with the market, causing the Fund during such periods to underperform funds that do not focus on dividends. The Fund’s focus on dividend paying investments may cause the Fund’s share price and total return to fluctuate more than those of funds that do not focus their investments on such investments.

Investment Strategy Risk − The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. There is no guarantee that the Fund’s investment objective will be achieved.

Equity Risk − The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Foreign Investments Risk − Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions, may affect the value of the Fund’s investments in foreign securities.

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

​

18

•

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:

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

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was [___]% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY.   Under normal circumstances, the Fund seeks to achieve its investment objective by investing at least 80% of its assets in equity securities. The sub-adviser, Wellington Management Company LLP (“Wellington Management”), uses fundamental analysis to identify securities that offer above average yields, below average valuations and the potential for dividend increases in the future. The Fund invests primarily in equity securities of companies with market capitalizations above $2 billion. At the time of investment, every equity security in which the Fund invests must pay a dividend or be expected to pay a dividend within the next 12 months. The Fund may invest up to 20% of its net assets in the securities of foreign issuers and non-dollar securities.

PRINCIPAL RISKS.   The primary risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective. For more information regarding risks and investment matters please see “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.

Market Risk − Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to the activities and financial prospects of individual companies or to general market and economic movements and trends, including adverse changes to credit markets.

19​

Dividend Paying Security Investment Risk − Income provided by the Fund may be affected by changes in the dividend policies of the companies in which the Fund invests and the capital resources available for such payments at such companies. Issuers that have paid regular dividends or distributions to shareholders may not continue to do so at the same level or at all in the future. Dividend paying securities can fall out of favor with the market, causing the Fund during such periods to underperform funds that do not focus on dividends. The Fund’s focus on dividend paying investments may cause the Fund’s share price and total return to fluctuate more than those of funds that do not focus their investments on such investments.

Value Investing Style Risk − Using a value investing style to select investments involves special risks, particularly if it is used as part of a “contrarian” approach to evaluating issuers. Overlooked or otherwise undervalued securities entail a significant risk of never attaining their potential value. Also, the value investing style may over time go in and out of favor. At times when the value investing style is out of favor, the Fund may underperform other equity funds that use different investing styles.

Investment Strategy Risk − The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. There is no guarantee that the Fund’s investment objective will be achieved.

Equity Risk − The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Foreign Investments Risk − Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions, may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments.

The Fund is subject to certain other risks, which are described elsewhere in the Fund’s statutory prospectus.
