Hartford Investment Financial Services, 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: 0.95% (Class A), 1.70% (Class B), 1.70% (Class C), 1.25% (Class R3), 0.95% (Class R4), 0.65% (Class R5) and 0.65% (Class Y). 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 29, 2012, and shall renew automatically for one-year terms 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 Fund.

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

· 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	$	543	$	758	$	990	$	1,656
B	$	673	$	871	$	1,195	$	1,959
C	$	273	$	540	$	931	$	2,028
R3	$	127	$	411	$	717	$	1,584
R4	$	97	$	318	$	556	$	1,241
R5	$	66	$	223	$	394	$	888
Y	$	63	$	199	$	346	$	774

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

Share Classes	Year 1		Year 3		Year 5		Year 10
A	$	543	$	758	$	990	$	1,656
B	$	173	$	571	$	995	$	1,959
C	$	173	$	540	$	931	$	2,028
R3	$	127	$	411	$	717	$	1,584

R5	$	66	$	223	$	394	$	888
Y	$	63	$	199	$	346	$	774

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 210% of the average value of its portfolio.

purposes, in corporate debt instruments; this policy may be changed at any time by a vote of the Fund’s Board of Directors, with at least 60 days prior written notice to shareholders. Corporate debt instruments in which the Fund may invest include, but are not limited to, debt securities of corporate and other non-governmental issuers, including dollar-denominated debt securities issued by foreign companies, as well as Bank Loans, convertible debt securities and repurchase agreements for those debt securities. The Fund invests, under normal circumstances, at least 65% of its total assets in securities rated “BBB” quality or better (by one or more NRSROs or, if unrated by an NRSRO, by the Fund’s sub-adviser) and may invest up to 35% of its total assets in non-investment grade debt securities (also known as “junk bonds”). The Fund invests at least 65% of its total assets in debt securities with a maturity of at least one year. The Fund may invest up to 35% of its total assets in bank loans or loan participation interests in secured or unsecured variable, fixed or floating rate loans to U.S. and foreign corporations, partnerships and other entities (collectively, “Bank Loans”). The Fund may invest up to 30% of its total assets in securities of foreign issuers and non-dollar securities (including investments in Bank Loans of foreign issuers) and 10% of its total assets in issues purchased as defaulted securities. The Fund may invest up to 15% of its total assets in preferred stocks, convertible securities, and warrants (including securities carrying warrants) to purchase equity securities or debt securities or loans. The Fund may also utilize derivatives (primarily futures and options contracts and swap agreements) to manage portfolio risk or for other investment purposes and may trade securities actively. While the Fund not may make direct purchases of common stock, from time to time the Fund may hold positions in common stock as a result of certain events, such as, among other things, the exercise of conversion rights or warrants, as well as restructurings or bankruptcy plans of reorganization with respect to an issuer’s securities held by the Fund.

MAIN 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 goal. For more information regarding risks and investment matters please see “Additional Information Regarding Risks and Investment Strategies” in the Fund’s 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.

Interest Rate Risk - The possibility that your investment may go down in value when interest rates rise, because when interest rates rise, the prices of bonds and fixed rate loans fall. Generally, the longer the maturity of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund’s income. These risks are greater during periods of rising inflation.

Credit Risk - Credit risk refers to the possibility that the issuer of a security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

Call Risk - Call risk is the risk that an issuer, especially during a period of falling interest rates, may redeem a security by repaying it early, which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates.

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.

Junk Bond Risk - Investments rated below investment grade (also referred to as “junk bonds”) are subject to heightened credit risk, which may make the fund more sensitive to adverse developments in the U.S. and abroad. Lower rated debt securities generally involve greater risk of default or price changes due to changes in the issuer’s creditworthiness than higher rated debt securities. The market prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. There may be little trading in the secondary market for particular debt securities which may make them more difficult to value or sell.

Bank Loans and Loan Participations Risk - Bank loans and loan participations are subject to credit risk, including the risk of nonpayment of principal or interest. Also, substantial increases in interest rates may cause an increase in loan defaults. Although the loans may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. In addition, in the event an agent bank becomes insolvent, a bank loan could be subject to settlement risks or administrative disruptions that could adversely affect the fund’s investment. It may also be difficult to obtain reliable information about a bank loan or loan participation.

Many loans are relatively illiquid or subject to restrictions on resale and may be difficult to value, which will have an adverse impact on the fund’s ability to dispose of particular bank loans or loan participations when necessary to meet redemption requests or liquidity needs, or to respond to a specific economic event, such as deterioration in the creditworthiness of the borrower. Bank loans may also be subject to extension risk and prepayment risk.

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, may affect the value of the Fund’s investments in foreign securities. Foreign securities will also subject the Fund’s investments to changes in currency rates.

Event Risk - Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.

Derivatives Risk - Derivatives are instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Successful use of derivative instruments by the Fund depends on the sub-adviser’s judgment with respect to a number of factors and the Fund’s performance could be worse than if it had not used these instruments. In addition, the fluctuations in the value of derivatives may not correlate perfectly with the overall securities markets.

Swap Agreements Risk - A swap agreement is a two-party contract that generally obligates the parties to exchange payments based upon a specified reference security, index or index component. Swaps can involve greater risks than direct investment in securities or other similar instruments, because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Futures and Options Risks - Futures and options may be more volatile than direct investments in the securities underlying the futures and options, may not correlate perfectly to the underlying securities, may involve additional costs, and may be illiquid. Futures and options also may involve a small initial investment relative to the risk assumed, which could result in losses greater than if they had not been used. Futures and options are also subject to the risk that the other party to the transaction defaults on its obligation.

Active Trading Risk - Active trading could increase the Fund’s transaction costs (thus affecting performance) and may increase your taxable distributions. These effects may also adversely affect Fund performance.

The Fund is subject to certain other risks, which are described elsewhere in this prospectus.

ADDITIONAL INFORMATION REGARDING RISKS AND INVESTMENT STRATEGIES

INVESTMENT GOAL. The Fund seeks to provide current income and long-term total return.

PRINCIPAL INVESTMENT STRATEGY. The Fund seeks its goal by investing primarily in a diversified portfolio consisting predominantly of corporate debt securities (including bank loans) that the sub-adviser, Hartford Investment Management Company (“Hartford Investment Management”), finds to be attractive giving consideration to both yield and total return. The Fund invests, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in corporate debt instruments; this policy may be changed at any time by a vote of the Fund’s Board of Directors, with at least 60 days prior written notice to shareholders. Corporate debt instruments in which the Fund may invest include, but are not limited to, debt securities of corporate and other non-governmental issuers, including dollar-denominated debt securities issued by foreign companies, as well as Bank Loans, convertible debt securities and repurchase agreements for those debt securities. The Fund invests, under normal circumstances, at least 65% of its total assets in securities rated “BBB” quality or better (by one or more NRSROs or, if unrated by an NRSRO, by the Fund’s sub-adviser) and may invest up to 35% of its total assets in non-investment grade debt securities (also known as “junk bonds”). The Fund invests at least 65% of its total assets in debt securities with a maturity of at least one year. The Fund may invest up to 35% of its total assets in bank loans or loan participation interests in secured or unsecured variable, fixed or floating rate loans to U.S. and foreign corporations, partnerships and other entities (collectively, “Bank Loans”). The Fund may invest up to 30% of its total assets in securities of foreign issuers and non-dollar securities (including investments in Bank Loans of foreign issuers) and 10% of its total assets in issues purchased as defaulted securities. The Fund may invest up to 15% of its total assets in preferred stocks, convertible securities, and warrants (including securities carrying warrants) to purchase equity securities or debt securities or loans. The Fund may also utilize derivatives (primarily futures and options contracts and swap agreements) to manage portfolio risk or for other investment purposes and may trade securities actively. While the Fund not may make direct purchases of common stock, from time to time the Fund may hold positions in common stock as a result of certain events, such as, among other things, the exercise of conversion rights or warrants, as well as restructurings or bankruptcy plans of reorganization with respect to an issuer’s securities held by the Fund.

“Investment grade” quality means securities that are rated at the time of purchase within the four highest categories assigned by Moody’s Investor Services, Inc. (“Aaa”, “Aa”, “A” or “Baa”) or Standard & Poor’s (“AAA”, “AA”, “A” or “BBB”) or Fitch, Inc. (“AAA”, “AA”, “A” or “BBB”) or are unrated securities that are judged by Hartford Investment Management to be of comparable quality to securities rated within these four highest categories. The Fund normally will maintain an average credit quality that is equivalent to at least “Baa3” by Moody’s.

Bonds in which the Fund invests may include, but are not limited to, (1) securities issued or guaranteed as to principal or interest by the U.S. Government, its agencies or instrumentalities; (2) non-convertible and convertible debt securities issued or guaranteed by U.S. corporations or other issuers (including foreign issuers); (3) asset-backed and mortgage-related securities, including collateralized mortgage obligations; (4) securities and loans issued or guaranteed as to principal or interest by a foreign issuer, including supranational entities such as development banks, non-U.S. corporations, banks or bank holding companies, or other foreign issuers; and (5) commercial mortgage-backed securities.

Although the Fund does not have a maximum maturity term restriction, the Fund tends to have a dollar-weighted average maturity of approximately 3-30 years.

Hartford Investment Management uses what is sometimes referred to as a top-down analysis to determine which sectors or industries may benefit or be harmed from current and future changes in the economy. The investment team then selects individual securities to buy or sell which, from a yield perspective, appear either attractive or unattractive. For individual securities, Hartford Investment Management assesses such factors as a company’s business environment, balance sheet, income statement, anticipated earnings, management team, and security structure.

Junk Bonds Risk - Although junk bonds generally pay higher rates of interest than investment grade bonds, junk bonds are high risk investments that may cause income and principal losses for a Fund. The major risks of junk bond investments include:

· Junk bonds may be issued by less creditworthy issuers. Issuers of junk bonds may have a larger amount of outstanding debt relative to their assets than issuers of investment grade bonds. In the event of an issuer’s bankruptcy, claims of other creditors may have priority over the claims of junk bond holders, leaving few or no assets available to repay junk bond holders.

· Prices of junk bonds are subject to extreme price fluctuations. Adverse changes in an issuer’s industry and general economic conditions may have a greater impact on the prices of junk bonds than on other higher rated fixed income securities.

· Issuers of junk bonds may be unable to meet their interest or principal payment obligations because of an economic downturn, specific issuer developments, or the unavailability of additional financing.

· Junk bonds frequently have redemption features that permit an issuer to repurchase the security from a Fund before it matures. If the issuer redeems junk bonds, a Fund may have to invest the proceeds in bonds with lower yields and may lose income.

· Junk bonds may be less liquid than higher rated fixed-income securities, even under normal economic conditions. There are fewer dealers in the junk bond market, and there may be significant differences in the prices quoted for junk bonds by the dealers. Because they are less liquid, judgment may play a greater role in valuing certain of the Fund’s securities than is the case with securities trading in a more liquid market.

· A Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer. The credit rating of a high yield security does not necessarily address its market value risk. Ratings and market value may change from time to time, positively or negatively, to reflect new developments regarding the issuer.

Bank and Corporate Loans Risk - Commercial banks and other financial institutions or institutional investors make corporate loans to companies that need capital to grow or restructure. Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the London Interbank Offered Rate (“LIBOR”) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. However, because the trading market for certain corporate loans may be less developed than the secondary market for bonds and notes, the Fund may experience difficulties in selling its corporate loans. Leading financial institutions often act as agent for a broader group of lenders, generally referred to

as a syndicate. The syndicate’s agent arranges the corporate loans, holds collateral and accepts payments of principal and interest. If the agent develops financial problems, the Fund may not recover its investment or recovery may be delayed. By investing in a corporate loan, the Fund may become a member of the syndicate.

The corporate loans in which the Fund invests are subject to the risk of loss of principal and income. Although borrowers frequently provide collateral to secure repayment of these obligations they do not always do so. If they do provide collateral, the value of the collateral may not completely cover the borrower’s obligations at the time of a default. If a borrower files for protection from its creditors under the U.S. bankruptcy laws, these laws may limit the Fund’s rights to its collateral. In addition, the value of collateral may erode during a bankruptcy case. In the event of a bankruptcy, the holder of a corporate loan may not recover its principal, may experience a long delay in recovering its investment and may not receive interest during the delay.

Loan Participation Risk - A participation interest is a fractional interest in a loan, issued by a lender or other financial institution. The lender selling the participation interest remains the legal owner of the loan. Where the Fund is a participant in a loan, it does not have any direct claim on the loan, and in the event of the borrower’s insolvency or default, the Fund, as a participant, would be a creditor of the lender and not of the borrower.

Foreign Investments Risk - Investments in foreign securities may be riskier than investments in U.S. securities. Foreign investments may be affected by the following:

· changes in currency rates

· changes in foreign or U.S. law or restrictions applicable to such investments and in exchange control regulations

· decreased liquidity

· substantially less volume on foreign stock markets and other securities markets

· higher commissions and dealer mark-ups

· inefficiencies in certain foreign clearance and settlement procedures that could result in an inability to execute transactions

· less uniform accounting, auditing and financial reporting standards

· less publicly available information about a foreign issuer or borrower

· less government regulation

· unfavorable foreign tax laws

· political or social instability or diplomatic developments in a foreign country

· differences in individual foreign economies.

· Governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth.

Derivatives Risk - Derivatives are instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. Derivatives are volatile and may involve significant risks, including:

· Credit Risk - the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable to honor its financial obligation to the Fund.

· Currency Risk - the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment.

· Leverage Risk - the risk associated with certain types of investments or trading strategies that relatively small market movements may result in large changes in the value of an investment. Certain investments or trading strategies that involve leverage can result in losses that greatly exceed the amount originally invested.

· Liquidity Risk - the risk that certain securities may be difficult or impossible to sell at the time that the seller would like or at the price that the seller believes the security is currently worth.

· Index Risk - if the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, the Fund could receive lower interest payments or experience a reduction in the value of the derivative to below what the Fund paid. Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

The Fund may use derivatives for hedging purposes, including anticipatory hedges. Hedging is a strategy in which the Fund uses a derivative to offset the risks associated with other Fund holdings. While hedging can reduce losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the Fund or if the cost of the derivative outweighs the benefit of the hedge. Hedging also involves the risk that changes in the value of the derivative will not match those of the holdings being hedged as expected by the Fund, in which case any losses on the holdings being hedged may not be reduced and may be increased. There can be no assurance that the Fund’s hedging strategy will reduce risk or that hedging transactions will be either available or cost effective. The Fund is not required to use hedging and may choose not to do so.

These transactions can result in sizeable realized and unrealized capital gains and losses relative to the gains and losses from the Fund’s direct investments in the reference assets and short sales.

Transactions in swaps can involve greater risks than if the Fund had invested directly in the reference asset since, in addition to general market risks, swaps may be leveraged and are also subject to illiquidity risk, counterparty risk, credit risk and valuation risk. Because they are two-party contracts and because they may have terms of greater than seven days, swap transactions may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap in the event of the default or bankruptcy of a swap counterparty. Some swaps may be complex and valued subjectively. Swaps may also be subject to pricing or “basis” risk, which exists when a particular swap becomes extraordinarily expensive relative to historical prices or the price of corresponding cash market instruments. Under certain market conditions it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity. If a swap transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

The prices of swaps can be very volatile, and a variance in the degree of volatility or in the direction of the price of the reference asset from the sub-adviser’s expectations may produce significant losses in a fund’s investments in swaps. In addition, a perfect correlation between a swap and an investment position may be impossible to achieve. As a result, the Fund’s use of swaps may not be effective in fulfilling the Fund’s investment strategies and may contribute to losses that would not have been incurred otherwise.

As a registered investment company, the Fund must “set aside” liquid assets (often referred to as “asset segregation”), or engage in other approved measures to “cover” open positions with respect to certain kinds of derivatives instruments. The Fund reserves the right to modify its asset segregation policies in the future to comply with any changes in the SEC’s positions regarding asset segregation. To the extent it sets aside assets equal to only its net obligations under cash-settled swaps, the Fund will have the ability to employ leverage to a greater extent than if the Fund was required to segregate assets equal to the full notional amount of the swaps.

Futures and Options Risks - Futures and options may be more volatile than direct investments in the securities underlying the futures and options and may not correlate perfectly to the underlying securities. Futures and options also involve additional expenses as compared to investing directly in the underlying securities, which could reduce any benefit or increase any loss to a Fund from using the strategy. Futures and options also may involve a small initial investment relative to the risk assumed, which could result in losses greater than if they had not been used. Options transactions may be effected on securities exchanges or in the over-the-counter market. When futures or options are purchased over-the-counter, a Fund bears the risk that the counter-party that wrote the future or option will be unable or unwilling to perform its obligations under the contract. Such futures and

options may also be illiquid, and in such cases, a Fund may have difficulty closing out its position or valuing the contract.

The Fund is subject to certain additional risks, which are discussed below.

Additional Risks and Investment Information.

Many factors affect the Fund’s performance. There is no assurance that the Fund will achieve its investment goal, and you should not consider any one fund alone to be a complete investment program. The different types of securities, investments, and investment techniques used by the Fund have attendant risks of varying degrees. The Statement of Additional Information contains more detailed information about the Fund’s investment policies and risks.

Emerging Markets Risk - The risks of foreign investments are usually much greater for emerging markets. Investments in emerging markets may be considered speculative. Emerging markets include those in countries defined as emerging or developing by the World Bank, the International Finance Corporation or the United Nations. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. They are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging markets have far lower trading volumes and less liquidity than developed markets. Since these markets are often small, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. In addition, traditional measures of investment value used in the United States, such as price to earnings ratios, may not apply to certain small markets. Also, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject. Many emerging markets have histories of political instability and abrupt changes in policies. As a result, their governments are more likely to take actions that are hostile or detrimental to private enterprise or foreign investment than those of more developed countries, including expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments. In such an event, it is possible that the Fund could lose the entire value of its investments in the affected market. Some countries have pervasive corruption and crime that may hinder investments. Certain emerging markets may also face other significant internal or external risks, including the risk of war, and ethnic, religious and racial conflicts. In addition, governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth. Emerging markets may also have differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments. Sometimes, they may lack or be in the relatively early

development of legal structures governing private and foreign investments and private property. In addition to withholding taxes on investment income, some countries with emerging markets may impose differential capital gains taxes on foreign investors.

Inverse Floater Risk - Inverse floaters earn interest at rates that vary inversely to changes in short-term interest rates. As short-term interest rates rise, inverse floaters produce less income and as short-term interest rates fall, inverse floaters produce more income. The prices and income of inverse floaters are generally more volatile than the prices and income of bonds with similar maturities. An investment in inverse floaters typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Inverse floaters generally will underperform the market for fixed rate municipal securities in a rising interest rate environment.

Mortgage-Backed and Other Asset-Backed Securities Risk - Mortgage-related and other asset-backed securities are subject to certain additional risks. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-backed securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, if the Fund holds mortgage-backed securities, it may exhibit additional volatility. This is known as “extension risk.” In addition, adjustable and fixed rate mortgage-backed securities are subject to “prepayment risk.” When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of a fund because the Fund may have to reinvest that money at lower prevailing interest rates. The Fund’s investments in other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as additional risks associated with the nature of the assets and the servicing of those assets.

The Fund may invest in mortgage-backed securities issued by the U.S. Government or by non-governmental issuers. To the extent that the Fund invests in mortgage-backed securities offered by non-governmental issuers, such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers, the Fund may be subject to additional risks. Timely payment of interest and principal of non-governmental issuers are supported by various forms of private insurance or guarantees, including individual loan, title, pool and hazard insurance purchased by the issuer. There can be no assurance that the private insurers can meet their obligations under the policies. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of a mortgage-backed security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their mortgages.

Counterparty Risk - The risk that the counterparty to an over-the-counter derivatives contract or a borrower of the Fund’s securities may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations.

Extension Risk - Rising interest rates could cause mortgage and loan prepayments to slow, which could increase the interest rate sensitivity of certain investments — such as mortgage- and asset-backed securities — and cause the value of these investments to fall.

Prepayment Risk - Falling interest rates may cause faster than expected prepayments of the mortgages and loans underlying the Fund’s mortgage- and asset-backed securities. When this happens, the Fund may have to reinvest the proceeds of these prepayments at lower rates, reducing the Fund’s income.

Illiquid Securities

· In General. Securities and other investments purchased by a Fund that are liquid at the time of purchase may subsequently become illiquid due to events relating to the issuer of the securities, market events, economic conditions or investor perceptions. Domestic and foreign markets are becoming more and more complex and interrelated, so that events in one sector of the market or the economy, or in one geographical region, can reverberate and have negative consequences for other market, economic or regional sectors in a manner that may not be reasonably foreseen. With respect to over-the-counter traded securities, the continued viability of any over-the-counter secondary market depends on the continued willingness of dealers and other participants to purchase the securities.

· Limitation on Illiquid Investments. If one or more instruments in a Fund’s portfolio become illiquid, a Fund may exceed its limit on illiquid instruments. In the event that this occurs, the Fund must take steps to bring the aggregate amount of illiquid instruments back within the prescribed limitations as soon as reasonably practicable. This requirement would not force a Fund to liquidate any portfolio instrument where the Fund would suffer a loss on the sale of that instrument.

· Valuation of Illiquid Investments. Where no clear indication of the value of a particular investment is available, the investment will be valued at its fair value according to the valuation procedures approved by the Boards of Directors. These cases include, among others, situations where the secondary markets on which a security has previously been traded are no longer viable for lack of liquidity. The value of illiquid securities may reflect a discount, which may be significant, from the market price of comparable securities for which a liquid market exists, and thus negatively affect a Fund’s NAV.

Volatility Risk - Share price, yield and total return may fluctuate more than with funds that use a different investment strategy.

Warrants Risk - If the price of the underlying stock does not rise above the exercise price before the warrant expires, the warrant generally expires without any value and the Fund loses any amount it paid for the warrant. Thus, investments in warrants may involve substantially more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.

Fund of Funds Structure — Underlying Funds

The term “fund of funds” refers to a mutual fund that pursues its investment goal by investing primarily in other mutual funds. The Fund may be an investment of one of the Hartford’s fund of funds.

Each fund of funds’ sub-adviser intends to manage the fund according to its asset allocation strategy, and does not intend to trade actively among the Underlying Funds or attempt to capture short-term market opportunities. However, a sub-adviser may modify a fund’s asset allocation strategy or its selection of Underlying Funds if it believes that doing so would better enable the fund to pursue its investment goal. The sub-advisers expect to reallocate Underlying Funds quarterly, although they may rebalance more or less frequently as market conditions warrant.

Risks Related To The Fund Of Funds Structure For Underlying Funds:

· A fund-of-funds structure could increase or decrease gains and could affect the timing, amount and character of distributions to you from the fund for investments you make directly in the fund.

· Rebalancing Underlying Funds may increase transaction costs.

· Management of a fund of funds entails potential conflicts of interest because a fund of funds invests in affiliated Underlying Funds. Certain Underlying Funds are more profitable to Hartford Life Insurance Company and/or its affiliates than others, and the sub-advisers may therefore have an incentive to allocate more of a fund’s assets to the more profitable Underlying Funds. To mitigate these conflicts, the sub-advisers have implemented various portfolio reporting and monitoring processes, including the implementation of a conflicts of interest policy overseen by the funds’ Board of Directors.

Other Investment Companies

Restrictions on Investments: Investments in securities of other investment companies, including exchange traded funds (ETFs), are subject to the following statutory limitations prescribed by the Investment Company Act of 1940, as amended (the “1940 Act”): Absent an available exemption (such as for affiliated funds), a fund may not

· acquire more than 3% of the voting shares of any other investment company,

· invest more than 5% of a fund’s total assets in securities of any one investment company, and

· invest more than 10% of its total assets in securities of all investment companies.

indirectly pay a proportional share of the asset-based fees of the ETFs in which the Fund invests. ETFs are also subject to specific risks depending on the nature of the ETF, such as liquidity risk, sector risk, and foreign and emerging market risk, as well as risks associated with fixed income securities, real estate investments and commodities. An investment in an ETF presents the risk that the ETF may no longer meet the listing requirements of any applicable exchanges on which the ETF is listed.

Use of Cash or Money Market Investments for Temporary Defensive Purposes

The Fund may invest some or all of its assets in cash or high quality money market securities (including money market funds managed by the investment manager or a sub-adviser) to maintain sufficient liquidity or for temporary defensive purposes in response to adverse market, economic or political conditions. To the extent a fund is in a defensive position, it may lose the benefit of market upswings and limit its ability to meet its investment goal.

About The Fund’s Investment Goal

The Fund’s investment goal may be changed without approval of the shareholders of the Fund. The Fund may not be able to achieve its goal. The Fund’s prospectus will be updated prior to any change in the Fund’s investment goal.

Consequences of Portfolio Trading Practices

Certain funds may have a relatively high portfolio turnover. Other funds may also, at times, engage in short-term trading. Such activity could produce higher brokerage expenses for a fund and higher taxable distributions to the fund’s shareholders and therefore could adversely affect the fund’s performance. The Fund is not managed to achieve a particular tax result for shareholders. Shareholders should consult their own tax adviser for individual tax advice.

Investment Policies

The Fund has a name which suggests a focus on a particular type of investment. In accordance with Rule 35d-1 under the 1940 Act, the Fund has adopted a policy that it will, under normal circumstances, invest at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in investments of the type suggested by its name, as set forth in the Fund’s Principal Investment Strategy section. This requirement is applied at the time the Fund invests its assets. If, subsequent to an investment by the Fund, this requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this requirement. In addition, in appropriate circumstances, synthetic investments may count toward the 80% minimum if they have economic characteristics similar to the other investments included in the basket. The Fund’s policy to invest at least 80% of its assets in such a manner is not a “fundamental” one, which means that it may be changed without the vote of a majority of the Fund’s outstanding shares as defined in the 1940 Act. The name of the Fund may be changed at any time by a vote of the Fund’s Board of Directors. Shareholders will be given written notice at least 60 days prior to any change by the Fund of its 80% investment policy covered by Rule 35d-1.

THE INVESTMENT MANAGER AND SUB-ADVISER

The Investment Manager

The Fund’s Investment Manager is the investment manager to each Hartford fund. The Investment Manager is a wholly owned, indirect subsidiary of The Hartford Financial Services Group, Inc. (“The Hartford”), a Connecticut financial services company with over $318.3 billion in assets as of December 31, 2010. As of the same date, the Investment Manager had over $59.4 billion in assets under management. The Investment Manager is responsible for the management of the Fund and supervises the activities of the investment sub-adviser described below. The Investment Manager is principally located at 200 Hopmeadow Street, Simsbury, Connecticut 06089.

The Investment Manager relies on an exemptive order from the Securities and Exchange Commission under which it uses a “Manager of Managers” structure. The Investment Manager has responsibility, subject to oversight by the Board of Directors, to oversee the sub-adviser and recommend its hiring, termination and replacement. The exemptive order permits the Investment Manager to appoint a sub-adviser not affiliated with the Investment Manager, with the approval of the Board of Directors and without obtaining approval from the Fund’s shareholders. Within 90 days after hiring any new sub-adviser, the shareholders will receive information about the new sub-advisory relationship.

The Investment Sub-Adviser

Hartford Investment Management provides day-to-day management for the Fund’s portfolio. Hartford Investment Management is a professional money management firm that provides services to investment companies, employee benefit plans, its affiliated insurance companies and other institutional accounts. Hartford Investment Management is a wholly-owned subsidiary of The Hartford. As of December 31, 2010, Hartford Investment Management had investment management authority over approximately $159.6 billion in assets. Hartford Investment Management is principally located at 55 Farmington Avenue, Hartford, Connecticut 06105.

Portfolio Managers. The Fund’s SAI provides additional information about the portfolio managers’ compensation, other accounts managed by the portfolio managers and the portfolio managers’ ownership of securities in the Fund.

Ira Edelblum, Senior Vice President of Hartford Investment Management, has served as a portfolio manager of the fund since December 2010. Prior to joining the firm in 2009, Mr. Edelblum was a Senior Managing Director and Senior Portfolio Manager at Bear Stearns Asset Management, where he was a member of the firm’s Portfolio Management Team and Investment Strategy Committee, with primary responsibility for Investment Grade Credit. Prior to that, Mr. Edelblum was a Managing Director and Senior Portfolio Manager at Times Square Asset Management. Mr. Edelblum began his career at BEA Associates (Credit Suisse Asset Management).

Michael Gray, CFA, Managing Director of Hartford Investment Management, has been involved in portfolio management of the fund since July 2008. Mr. Gray joined Hartford Investment Management in 2006. Previously, Mr. Gray was managing director and global head of credit research at Credit Suisse Asset Management. Prior to Credit Suisse, Mr. Gray served in similar capacities at Deutsche Asset Management and UBS Warburg.

James Serhant, CFA, Senior Vice President of Hartford Investment Management, has served as a portfolio manager of the Fund since December 2010. Mr. Serhant joined Hartford Investment Management in 2005, and also serves as a Senior Credit Research Analyst responsible for the credit research analysis of leveraged credit issuers. Prior to joining the firm, he was a vice president and senior research analyst at Delaware Investments (2001-2005). From 1997-2000, he was vice president and senior fixed income research analyst at JP Morgan Securities, Inc.

Soft Dollar Practices

The sub-advisers are responsible for the day-to-day portfolio management activities of the funds they sub-advise, including effecting securities transactions. To the extent consistent with Section 28(e) of the Securities Exchange Act of 1934 (the “1934 Act”), the sub-advisers may obtain “soft dollar” benefits in connection with the execution of transactions for the funds. Each sub-adviser may cause a fund to pay a broker-dealer an amount in excess of the amount that another broker-dealer would have charged for the same transaction, in exchange for “brokerage and research services” (as defined in the 1934 Act). Neither the management fees nor the sub-advisory fees are reduced because the sub-advisers receive these products and services. These products and services may be of value to the sub-advisers in advising their clients (including the funds), although not all of these products and services are necessarily useful and of value in managing the funds. These products and services may include research reports, access to management personnel, financial newsletters and trade journals, seminar and conference fees, quantitative analytical software, data services, communication services relating to (or incidental to) the execution, clearing and settlement of securities transactions, post-trade services relating to functions incidental to trade execution, and other products and services that are permitted under Section 28(e), as interpreted by the SEC from time to time. In certain instances, these products and services may have additional uses that are not related to brokerage or research. For such “mixed use” items, in accordance with SEC guidance, the sub-adviser will make a reasonable allocation of the cost of the item according to its expected use, and will pay for that portion of the item that does not have a brokerage or research-related component out of its own pocket.

MANAGEMENT FEE. The Fund pays a monthly management fee to the Investment Manager based on a stated percentage of the Fund’s average daily net asset value. A discussion regarding the basis for the Board of Directors’ approval of the investment management and investment sub-advisory agreements of the Fund is available in the Fund’s annual report to shareholders for the fiscal year ended October 31, 2010.

CLASSES OF SHARES

The Fund offers for sale seven classes of shares: Class A, Class B, Class C, Class R3, Class R4, Class R5 and Class Y. Class B shares were closed to new investments as of September 30, 2009 and are no longer available for purchase except through reinvestment of dividends or by exchange for Class B shares of another Hartford Mutual Fund.

Investor Requirements.

This section describes investor requirements for each class of shares offered by the Hartford Mutual Funds. The Fund offers the classes of shares described above and not all share classes discussed below are available for this Fund.

Class A and Class C Shares — Class A and Class C shares have no eligibility requirements.

Class B Shares — Effective at the close of business on September 30, 2009 (the “Close Date”), no new or additional investments are allowed in Class B shares of the Fund (including investments through any systematic investment plan). Shareholders of Class B shares as of the Close Date may continue to hold their Class B shares, exchange their Class B shares for Class B shares of another Hartford Mutual Fund (as permitted by existing exchange privileges), and redeem their Class B shares as described in this prospectus. Reinstatement privileges with respect to Class B shares are as described under “Reinstatement Privilege.” If you have chosen to reinvest capital gains and dividends, any such capital gains or dividends on Class B shares will continue to be reinvested in Class B shares of the Fund. For Class B shares outstanding as of the Close Date, all Class B share attributes, including the 12b-1 fee, contingent deferred sales charge schedule, and conversion to Class A shares remain unchanged.

Class B shareholders who wish to make additional investments in the Fund are permitted to invest in other classes of the Fund, subject to the pricing, fee schedule and eligibility requirements of those classes. For direct (non-broker-controlled) accounts, new investments in Class B shares made after the Close Date will be redirected to Class A shares at the appropriate sales charge. Investments in Class B shares made through any systematic investment plan in effect after the Close Date will automatically be redirected to Class A shares. Shareholders wishing to make changes to their systematic investment plan may do so by accessing their account at www.hartfordmutualfunds.com or by calling 1-888-843-7824. For broker-controlled accounts, new investments in Class B will not be accepted, and you should contact your Financial Advisor to make appropriate adjustments to any systematic investment plan in effect with respect to closed Class B shares.

Please contact your financial advisor or 1-888-843-7824 with any questions.

Class I Shares — Class I shares are only offered:

with the Fund, whose use of Class I shares will depend on the structure of the particular advisory fee-based wrap program, and

· to current or retired officers, directors and employees (and their families, as defined below under the “Accumulation Privilege” section) of the Fund, The Hartford, the sub-advisers to the Hartford Mutual Funds, the transfer agent, and their affiliates.

These eligible investors may purchase Class I shares at net asset value without an additional distribution fee. Ineligible investors who select Class I shares will be issued Class A shares. Class A shares are subject to a front-end sales charge and distribution fee unless an investor qualifies for the waiver of the Class A front-end sales charge.

Class R3, Class R4 and Class R5 Shares — Class R3, R4 and R5 shares are available only to 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit-sharing and money purchase pension plans, defined benefit plans, nonqualified deferred compensation plans and 529 college savings plans. Class R3, R4 and R5 shares also generally are available only to retirement plans where plan level or omnibus accounts are held on the books of the Fund; however, the Fund reserves the right in its sole discretion to waive this requirement. Class R3, R4 and R5 shares are not available to retail non-retirement accounts, Traditional and Roth Individual Retirement accounts (IRAs), Coverdell Education Savings Accounts, SEPs, SARSEPs, SIMPLE IRAs and individual 403(b) plans.

Class Y Shares — Class Y shares are available only to certain eligible investors, as set forth below.

· Class Y shares are offered to institutional investors, which include, but are not limited to:

· Certain qualified employee benefit plans and other retirement savings plans

· Non-profit organizations, charitable trusts, foundations and endowments

· Accounts registered to bank trust departments, trust companies, and investment companies

· Class Y shares are not available to individual investors, unless such investors purchased their shares prior to March 1, 2008 and wish to add to their existing account. Class Y shares are also not available to retail, advisory fee-based wrap programs or to adviser-sold donor-advised funds.

· Class Y shares are only available to those institutional investors that have invested or agree to invest at least $1,000,000 in the Hartford Mutual Funds. This investment minimum does not apply to qualified employee benefit plans and other retirement savings plans.

Certain employer-sponsored retirement plans with at least 100 participants or $500,000 in plan assets, participants in retirement plans investing in Fund shares through group variable funding agreements issued by Hartford Life Insurance Company and participants in retirement plans where Hartford Life Insurance Company or an affiliate is the plan administrator may invest in Class A shares without any sales charge, provided they included (or were offered) the Fund as an

investment option on or before June 30, 2007. Such plans may continue to purchase Class A shares without any sales charge after July 1, 2007. Effective July 1, 2007, only Classes R3, R4, R5 and Y will be offered to employer-sponsored retirement plans that do not already own (or were offered) Class A shares.

The Fund may, in its sole discretion, modify or waive the eligibility requirements for purchases of any class of its shares.

Choosing a Share Class

Each share class has its own cost structure, allowing you to choose the one that best meets your needs. For actual past expenses of each share class, see the Fund information earlier in this prospectus. Your financial representative can help you decide.

In making your decision regarding which share class may be best for you to invest in, please keep in mind that your financial representative or plan administrator may receive different compensation depending on the share class that you invest in and you may receive different services in connection with investments in different share classes. Investors should consult with their financial intermediary about the comparative pricing and features of each share class, the services available for shareholders in each share class, the compensation that will be received by their financial intermediary in connection with each share class and other factors that may be relevant to the investor’s decision as to the best share class in which to invest.

Each class, except Class I, Class R5 and Class Y, has adopted a Rule 12b-1 plan that allows the class to pay distribution fees for the sale and distribution of its shares and for providing services to shareholders. Because these fees are paid out of the Fund’s assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

	Sales Charge	Deferred Sales Charge (Load)	Distribution and Services (12b-1) Fees(1)	Administrative Fee(1)
Class A	Described under the subheading “How Sales Charges are Calculated”	Described under the subheading “How Sales Charges are Calculated”	0.25%	None

(1) As a percentage of the Fund’s average net assets.

(2) Automatic conversion to Class A shares after eight years, thus reducing future annual expenses.

(3) No automatic conversion to Class A shares, so annual expenses continue at the Class C level throughout the life of your investment.

How Sales Charges Are Calculated

Class A sales charges and commissions paid to dealers for the Fund are as follows. The offering price includes the front-end sales load.

YOUR INVESTMENT	As a % of Offering Price		As a % of Net Investment		Dealer Commission-As Percentage of Offering Price
Less than $50,000	4.50	%	4.71	%	3.75	%
$ 50,000 — $ 99,999	4.00	%	4.17	%	3.50	%
$100,000 — $249,999	3.50	%	3.63	%	3.00	%
$250,000 — $499,999	2.50	%	2.56	%	2.00	%
$500,000 — $999,999	2.00	%	2.04	%	1.75	%
$1 million or more(1)	0	%	0	%	0	%

(1) Investments of $1 million or more in Class A shares may be made with no front-end sales charge. However, there is a contingent deferred sales charge (CDSC) of 1.00% on any Class A shares sold within 18 months of purchase. For purposes of this CDSC, all purchases made during a calendar month are counted as having been made on the first day of that month. The CDSC is based on the lesser of the original purchase cost or the current market value of the shares being sold and is not charged on shares you acquired by reinvesting your dividends and capital gains distributions. To keep your CDSC as low as possible, each time you place a request to sell shares we will first sell any shares in your account that are not subject to a CDSC.

In order to determine the dollar amount of the sales charges you pay, we multiply the applicable percentage by the dollar amount of your desired investment. The total dollar amount of the sales charge is rounded to two decimal places using standard rounding criteria and is included in the public offering prices of the Fund. Your total purchase amount is then divided by the Fund’s per share public offering price to determine the number of shares you receive in the Fund. This number is also rounded to three decimal places using standard rounding criteria. Because of rounding discussed above, the front-end sales charge you pay, when expressed as a percentage of the offering price, may be higher or lower than the amount as stated in the Fund’s fee table (as illustrated in the table above).

For example, you want to invest $100.00 in Class A shares of a Fund. Assume the shares have a public offering price of $15.72 (includes front-end sales charge), a total net asset value of $14.86, and a front-end sales charge of 5.5%. The total dollar amount of the sales charge would be $5.48; the total net asset value of the shares purchased would be $94.52; and the total number of shares purchased

would equal 6.361 shares. Therefore, the calculated sales charge rate is 5.48% (sales charge paid divided by the net investment). Please note that this example is a hypothetical and is not intended to represent the value of any Hartford Mutual Fund.

The distributor may pay up to the entire amount of the sales commission to particular broker-dealers. The distributor may pay dealers of record commissions on purchases over $1 million in an amount of up to 1.00% of the first $4 million, plus 0.50% of the next $6 million, plus 0.25% of share purchases over $10 million or of purchases in any amount by adviser-sold donor-advised funds. This commission schedule may also apply to certain sales of Class A shares made to investors that qualify under any of the last four categories listed under “Waivers for Certain Investors.”

For retirement plans established on or after March 1, 2007, the commission schedule and 1.00% CDSC will not apply.

Class B sales charges are listed below. There is no CDSC on shares acquired through reinvestment of dividends and capital gains distributions. The CDSC is based on the original purchase cost or the current market value of the shares being sold, whichever is less. Note that after 8 years, Class B shares convert to Class A shares.

2nd year	4.00	%
3rd year	3.00	%
4th year	3.00	%

Class C sales charges are listed below. There is no CDSC on shares acquired through reinvestment of dividends and capital gains distributions. The CDSC is based on the original purchase cost or the current market value of the shares being sold, whichever is less. A front-end sales charge is not assessed on Class C shares.

After 1 year	None

For purposes of Class B and Class C CDSCs, all purchases made during a calendar month are counted as having been made on the first day of that month. To determine whether a CDSC applies, the Fund redeems shares in the following order: (1) shares acquired through reinvestment of dividends and capital gains distributions, (2) Class B shares held for over 6 years or Class C shares held over 1 year, and (3) Class B shares held the longest during the six-year period. Please note that for purposes of the expense examples and performance returns shown in this prospectus, the figures include the effect of Class B and Class C CDSCs as if they had been incurred prior to the expiration of the applicable period.

When requesting a redemption, the amount withdrawn from your account will equal the specified dollar amount of the redemption request plus the dollar amount of any applicable CDSC. If you do not want any additional amount withdrawn from your account to cover the CDSC due, please indicate that the applicable CDSC should be withdrawn from the total distribution amount requested.

Proceeds from the CDSC are paid to the distributor and are used in whole or in part by the distributor to defray its expenses related to providing distribution-related services to the Fund in connection with the sale of the Class A, Class B and Class C shares, such as the payment of compensation to select selling brokers for selling these classes of shares. The combination of the CDSC and the distribution and service fees facilitates the ability of the Fund to sell the Class B and Class C shares without a front-end sales charge being deducted, and to sell Class A shares with a 3.00%, 4.50% or 5.50% maximum sales charge, as applicable, at the time of the purchase.

Although the Fund does not charge a transaction fee, you may be charged a fee by brokers or financial intermediaries for the purchase or sale of the Fund’s shares through that broker or financial intermediary. This transaction fee is separate from any sales charge that the Fund may apply.

Sales Charge Reductions And Waivers — Class A and Class C shares

Reducing Your Class A Sales Charges There are several ways you can combine multiple purchases of Class A shares of the Fund to take advantage of the breakpoints in the sales charge schedule. Please note that you or your broker must notify Hartford Administrative Services Company (“HASCO”), the Fund’s transfer agent, that you are eligible for these breakpoints every time you have a qualifying transaction.

· Accumulation Privilege — lets you add the value of any shares of the Fund (excluding Class R3, R4 and R5 shares) you or members of your family already own to the amount of your next Class A investment for purposes of calculating the sales charge you will pay on that investment. The Fund offers to all qualifying investors rights of accumulation under which investors are permitted to purchase Class A shares of any fund of The Hartford Mutual Funds, Inc., The Hartford Mutual Funds II, Inc. and SMART529 Accounts at the price applicable to the total of (a) the dollar amount then being purchased plus (b) an amount equal to the then-current net asset value of the purchaser’s holdings of all shares of all funds of The Hartford Mutual Funds, Inc., The Hartford Mutual Funds II, Inc. and SMART529 Accounts. For purposes of the rights of accumulation program, the purchaser may include all shares owned by family members. The definition of family member varies depending upon when the purchaser opened the account. For accounts opened on or after August 16, 2004, a family member is the owner’s spouse (or legal equivalent recognized under state law) and any children under 21. For accounts opened before August 16, 2004, a family member is an owner’s spouse (or legal equivalent recognized under state law), parent, grandparent, child, grandchild, brother, sister, step-family members and in-laws. As of August 16, 2004, account values invested in fixed annuity, variable

annuity and variable life insurance products will no longer be considered towards the accumulation privilege. Participants in retirement plans receive breakpoints at the plan level. Acceptance of the purchase order is subject to confirmation of qualification. The rights of accumulation may be amended or terminated at any time as to subsequent purchases.

· Letter Of Intent — lets you purchase Class A shares of the Fund over a 13-month period and receive the same sales charge as if all shares had been purchased at once. Any person may qualify for a reduced sales charge on purchases of Class A shares made within a thirteen-month period pursuant to a Letter of Intent (“LOI”). Please note: retirement plans that receive breakpoints at the plan level do not qualify for the LOI privilege. Class A shares acquired through the reinvestment of distributions do not constitute purchases for purposes of the LOI. A Class A shareholder may include, as an accumulation credit towards the completion of such LOI, the value of all shares of all funds of The Hartford Mutual Funds, Inc., The Hartford Mutual Funds II, Inc. and SMART529 Accounts owned by the shareholder as described above under “Accumulation Privilege.” Such value is determined based on the public offering price on the date of the LOI. During the term of a LOI, HASCO will hold shares in escrow to secure payment of the higher sales charge applicable for shares actually purchased if the indicated amount on the LOI is not purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated on the LOI has been purchased. A LOI does not obligate the investor to buy or the Fund to sell the indicated amount of the LOI. If a Class A shareholder exceeds the specified amount of the LOI and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of the expiration of the LOI. The resulting difference in offering price will purchase additional Class A shares for the shareholder’s account at the applicable offering price. If the specified amount of the LOI is not purchased, the shareholder shall remit to HASCO an amount equal to the difference between the sales charge paid and the sales charge that would have been paid had the aggregate purchases been made at a single time. If the Class A shareholder does not within twenty days after a written request by HASCO pay such difference in sales charge, HASCO will redeem an appropriate number of escrowed shares in order to realize such difference. Purchases based on a LOI may include holdings as described above under “Accumulation Privilege.” Additional information about the terms of the LOI is available from your registered representative or from HASCO at 1-888-843-7824.

Waivers For Certain Investors Class A shares may be offered without front-end sales charges to the following individuals and institutions:

· selling broker-dealers and their employees and sales representatives (and their families, as defined above under the “Accumulation Privilege” section) provided, however, that only those employees of such broker-dealers who, as a part of their usual duties, provide services related to transactions in Fund shares shall qualify,

· financial representatives utilizing Fund shares in fee-based investment products under a signed agreement with the Fund,

· current or retired officers, directors and employees (and their families, as defined above under the “Accumulation Privilege” section) of the Fund, The Hartford, the sub-advisers to the Hartford Mutual Funds, the transfer agent, and their affiliates. Such individuals may also purchase Class I shares at net asset value,

· welfare benefit plans investing in Fund shares through group variable funding agreements issued by Hartford Life Insurance Company,

· participants in certain employer-sponsored retirement plans with at least 100 participants or $500,000 in plan assets, participants in retirement plans investing in Fund shares through group variable funding agreements issued by Hartford Life Insurance Company and participants in retirement plans where Hartford Life Insurance Company or an affiliate is the plan administrator that included (or were offered) the Fund as an investment option on or before June 30, 2007,

· one or more members of a group (and their families, as defined above under the “Accumulation Privilege” section) of at least 100 persons engaged or previously engaged in a common business, profession, civic or charitable endeavor or other activity (1.00% CDSC applies if redeemed within 18 months), and

· college savings program that is a qualified state tuition program under section 529 of the Internal Revenue Code (“529 Plan”), and adviser-sold donor advised funds (a 1.00% CDSC applies if the adviser-sold donor advised fund redeems within eighteen months).

In order to receive the sales charge reductions or waivers, you must notify the transfer agent of the reduction or waiver request when you place your purchase order. The transfer agent may require evidence of your qualification for such reductions or waivers. Additional information about the sales charge reductions or waivers can be obtained from the transfer agent. The 1.00% CDSCs indicated above also may be waived where the distributor does not compensate the broker for the sale.

CDSC Waivers As long as the transfer agent is notified at the time you sell, the CDSC for each applicable share class will generally be waived in the following cases:

· to make Systematic Withdrawal Plan payments that are limited annually to no more than 12% of the value of the account at the time the plan is initiated,

· for death or disability except in the case of a transfer or rollover to a company not affiliated with The Hartford,

· under reorganization, liquidation, merger or acquisition transactions involving other investment companies,

· for retirement plans under the following circumstances:

DISTRIBUTION ARRANGEMENTS

Hartford Investment Financial Services, LLC (“HIFSCO”) serves as the principal underwriter for the Fund pursuant to an Underwriting Agreement initially approved by the Board of Directors of the Hartford Mutual Funds (the “Company”). HIFSCO is a registered broker-dealer and member of the Financial Industry Regulatory Authority (“FINRA”). Shares of the Fund are continuously offered and sold by selected broker-dealers who have selling agreements with HIFSCO. Such selected broker-dealers may designate and authorize other financial intermediaries to offer and sell shares of the Fund. Except as discussed below, HIFSCO bears all the expenses of providing services pursuant to the Underwriting Agreement including the payment of the expenses relating to the distribution of prospectuses for sales purposes as well as any advertising or sales literature. HIFSCO is not obligated to sell any specific amount of shares of the Fund.

Distribution Plans — Class A, Class B, Class C, Class R3 and Class R4 Shares

Class A Plan Pursuant to the Class A Plan, the Fund may compensate HIFSCO for its expenditures in financing any activity primarily intended to result in the sale of Fund shares and for maintenance and personal service provided to existing Class A shareholders. The expenses of the Fund pursuant to the Class A Plan are accrued on a fiscal year basis and may not exceed, with respect to the Class A shares of the Fund, the annual rate of 0.25% of the Fund’s average daily net assets attributable to Class A shares. The Company’s Board of Directors has currently authorized Rule 12b-1 payments up to 0.25% of the Fund’s average daily net assets attributable to Class A shares. The entire amount of the fee may be used for shareholder servicing expenses with the remainder, if any, used for distribution expenses. HIFSCO or its affiliates are entitled to retain all service fees payable under the Class A Plan for which there is no dealer of record or for which qualification standards have not been met as partial consideration for personal services and/or account maintenance services performed by HIFSCO or its affiliates for shareholder accounts.

Class B Plan Pursuant to the Class B Plan, the Fund may pay HIFSCO a fee of up to 1.00% of the average daily net assets attributable to Class B shares, 0.75% of which is a fee for distribution financing activities and 0.25% of which is for shareholder account services. HIFSCO will advance to dealers the first-year service fee at a rate equal to 0.25% of the amount invested. As compensation for such advance, HIFSCO may retain the service fee paid by the Fund with respect to such shares for the first year after purchase. Dealers will become eligible for additional service fees with respect to such shares commencing in the thirteenth month following purchase. Brokers may from time to time be required to meet certain other criteria in order to receive service fees. HIFSCO or its affiliates are entitled to

retain all service fees payable under the Class B Plan for which there is no dealer of record or for which qualification standards have not been met as partial consideration for personal services and/or account maintenance services performed by HIFSCO or its affiliates for shareholder accounts. The Class B Plan also provides that HIFSCO will receive all contingent deferred sales charges attributable to Class B shares.

Class C Plan Pursuant to the Class C Plan, the Fund may pay HIFSCO a fee of up to 1.00% of the average daily net assets attributable to Class C shares, 0.75% of which is a fee for distribution financing activities and 0.25% of which is for shareholder account services. HIFSCO will advance to dealers the first-year service fee at a rate equal to 0.25% of the amount invested. As compensation for such advance, HIFSCO may retain the service fee paid by the Fund with respect to such shares for the first year after purchase. Dealers will become eligible for additional service fees with respect to such shares commencing in the thirteenth month following purchase. Brokers may from time to time be required to meet certain other criteria in order to receive service fees. HIFSCO or its affiliates are entitled to retain all service fees payable under the Class C Plan for which there is no dealer of record or for which qualification standards have not been met as partial consideration for personal services and/or account maintenance services performed by HIFSCO or its affiliates for shareholder accounts. The Class C Plan also provides that HIFSCO will receive all contingent deferred sales charges attributable to Class C shares.

Class R3 Plan Pursuant to the Class R3 Plan, the Fund may pay HIFSCO a fee of up to 0.50% of the average daily net assets attributable to Class R3 shares for distribution financing activities and up to 0.25% may be used for shareholder account services. HIFSCO will pay dealers the service fee at a rate equal to 0.50% of the amount invested. Brokers may from time to time be required to meet certain other criteria in order to receive such service fees. HIFSCO or its affiliates are entitled to retain all service fees payable under the Class R3 Plan for which there is no dealer of record or for which qualification standards have not been met as partial consideration for personal services and/or account maintenance services performed by HIFSCO or its affiliates for shareholder accounts.

Class R4 Plan Pursuant to the Class R4 Plan, the Fund may pay HIFSCO a fee of up to 0.25% of the average daily net assets attributable to Class R4 shares for distribution financing activities and the entire amount may be used for shareholder account services. HIFSCO will pay dealers the service fee at a rate equal to 0.25% of the amount invested. Brokers may from time to time be required to meet certain other criteria in order to receive such service fees. HIFSCO or its affiliates are entitled to retain all service fees payable under the Class R4 Plan for which there is no dealer of record or for which qualification standards have not been met as partial consideration for personal services and/or account maintenance services performed by HIFSCO or its affiliates for shareholder accounts.

compensation to employees of HIFSCO, (c) compensation to and expenses, including overhead such as communications and telephone, training, supplies, photocopying and similar types of expenses, of HIFSCO incurred in the printing and mailing or other dissemination of all prospectuses and statements of additional information, (d) the costs of preparation, printing and mailing of reports used for sales literature and related expenses, i.e., advertisements and sales literature, and (e) other distribution-related expenses and for the provision of personal service and/or the maintenance of shareholder accounts. These Plans are considered compensation type plans, which means that the Fund pays HIFSCO the entire fee regardless of HIFSCO’s expenditures. Even if HIFSCO’s actual expenditures exceed the fee payable to HIFSCO at any given time, the Fund will not be obligated to pay more than that fee.

In accordance with the terms of the Plans, HIFSCO provides to the Fund, for review by the Company’s Board of Directors, a quarterly written report of the amounts expended under the respective Plans and the purpose for which such expenditures were made. In the Board of Directors’ quarterly review of the Plans, they review the level of compensation the Plans provide.

The Plans were adopted by a majority vote of the Board of Directors of the Company, including at least a majority of directors who are not, and were not at the time they voted, interested persons of the Fund as defined in the 1940 Act and do not and did not have any direct or indirect financial interest in the operation of the Plans, cast in person at a meeting called for the purpose of voting on the Plans. In approving the Plans, the directors identified and considered a number of potential benefits which the Plans may provide including the potential to increase assets and possibly benefit from economies of scale, the potential to avoid a decrease in assets through redemption activity, the ability to sell shares of the Fund through adviser and broker distribution channels, and the ability to provide investors with an alternative to paying front end sales loads. The Board of Directors of the Company believes that there is a reasonable likelihood that the Plans will benefit the Fund and its current and future shareholders. Under their terms, the Plans remain in effect from year to year provided such continuance is approved annually by vote of the directors of the Board in the manner described above. The Plans may not be amended to increase materially the amount to be spent for distribution without approval of the shareholders of each applicable class, and material amendments to the Plans must also be approved by the Board of Directors in the manner described above. A Plan may be terminated at any time, without payment of any penalty, by vote of the majority of the directors of the Board who are not interested persons of the Fund and have no direct or indirect financial interest in the operations of the Plan, or by a vote of a “majority of the outstanding voting securities” of the applicable class. A Plan will automatically terminate in the event of its assignment.

Payments to Financial Intermediaries and Other Entities

This section includes additional information about different types of compensation paid by HIFSCO and its affiliates to other entities with respect to the Hartford Mutual Funds.

Commissions and Rule 12b-1 Payments. HIFSCO and its affiliates make a variety of payments to broker-dealers and financial institutions (“Financial Intermediaries”) that sell the shares of, and/or provide services to, the Hartford Mutual Funds. HIFSCO pays sales commissions and Rule 12b-1 fees to Financial Intermediaries. The Fund’s SAI includes information regarding these commission and Rule 12b-1 payments by share class.

As explained in more detail below under “Compensation to Servicing Intermediaries,” HIFSCO and its affiliates make additional payments to Financial Intermediaries and other intermediaries that provide certain services with respect to the Hartford Mutual Funds (“Servicing Intermediaries”).

The commissions and other payments that Financial Intermediaries and their affiliates receive for selling and providing services to investment products can vary from one product to another. For this reason, if your Financial Intermediary receives greater payments with respect to the Hartford Mutual Funds than he or she receives with respect to other products, he or she may be more inclined to sell you shares of a Hartford Mutual Fund rather than another product.

Additional Compensation Payments to Financial Intermediaries. In addition to sales commissions and 12b-1 fees, HIFSCO and its affiliates also make payments out of their own assets to Financial Intermediaries to encourage the sale of the Hartford Mutual Funds’ shares (“Additional Payments”). These Additional Payments may give your Financial Intermediary a reason to sell and recommend the Hartford Mutual Funds, over other products for which he or she may receive less compensation. You may contact your Financial Intermediary if you want information regarding the payments it receives.

The amount of any Additional Payments made to a Financial Intermediary is generally based on one or more of the following criteria: (i) the average net assets of the Hartford Mutual Funds that are attributed to that Financial Intermediary; (ii) the amount of Hartford Mutual Fund assets held for over one year by customers of that Financial Intermediary; and (iii) the amount of the Hartford Mutual Fund shares sold through that Financial Intermediary. The annual amount of Additional Payments made to any one Financial Intermediary is normally not expected to (although it may from time to time) exceed 0.12% of the average net assets of the Hartford Mutual Funds that are attributed to that Financial Intermediary. For the calendar year ended December 31, 2010, HIFSCO and its affiliates incurred approximately $34.6 million in total Additional Payments to Financial Intermediaries.

Additional Payments may be used for various purposes and take various forms, such as:

· Payments for putting Hartford Mutual Funds on a Financial Intermediary’s list of mutual funds available for purchase by its customers;

· Payments for including Hartford Mutual Funds within a group that receives special marketing focus or placing Hartford Mutual Funds on a “preferred list”;

· “Due diligence” payments for a Financial Intermediary’s examination of the Hartford Mutual Funds and payments for providing extra employee training and information relating to the Hartford Mutual Funds;

· “Marketing support fees” for providing assistance in promoting the sale of Hartford Mutual Fund shares;

· Sponsorships of sales contests and promotions where participants receive prizes such as travel awards, merchandise, cash or recognition;

· Provision of educational programs, including information and related support materials;

· Provision of computer hardware and software; and

· Occasional meals and entertainment, tickets to sporting events, nominal gifts and travel and lodging (subject to applicable rules and regulations).

As of January 1, 2011, HIFSCO has entered into ongoing contractual arrangements to make Additional Payments to the Financial Intermediaries listed below. . Financial Intermediaries that received Additional Payments in 2010 for items such as sponsorship of meetings, education seminars and travel and entertainment, but do not have an ongoing contractual relationship with HIFSCO, are listed in the SAI.

Hartford Mutual Funds rather than to other investments products for which it may receive a lower payment. You may contact your Servicing Intermediary if you want additional information regarding any Servicing Payments it receives.

The amount of the Servicing Payments is generally based on average net assets of the Hartford Mutual Funds that are attributed to a Servicing Intermediary. With certain limited exceptions, the annual amount of Servicing Payments made to any specific Servicing Intermediary is not expected to (although it may from time to time) exceed 0.20% of the average net assets of the Hartford Mutual Funds that are attributed to that Servicing Intermediary. For the year ended December 31, 2010, HIFSCO incurred approximately $1,114,000 in total Servicing Payments and these Servicing Payments did not exceed $784,000 for any one Servicing Intermediary.

Servicing Payments are also paid to certain Servicing Intermediaries by HASCO out of the transfer agency fees it receives from the Hartford Mutual Funds. Although some of these payments are calculated based on average net assets of the Hartford Mutual Funds that are attributed to the Servicing Intermediary, Servicing Intermediaries are generally paid a per account fee up to a maximum of $19 per account.

Because of legal and tax restrictions on withdrawals from retirement accounts, you will not be allowed to enter a redemption request for these types of accounts online.

· By Phone — Only non-retirement accounts or IRA plans where the shareowner is age 59 1/2 or older may redeem by telephone, and sales are restricted to up to $50,000 per shareowner per market day. First, call the transfer agent to verify that the telephone redemption privilege is in place on your account, or to request the forms to add it to an existing account. Then, to place your order, call the transfer agent at 1-888-THE-STAG (843-7824) between 8 A.M. and 7 P.M. Eastern Time (between 7 A.M. and 6 P.M. Central Time) Monday through Thursday and between 9:15 A.M. and 6 P.M. Eastern Time (between 8:15 A.M. and 5 P.M. Central Time) on Friday. Complete transaction instructions on a specific account must be received in good order and confirmed by The Hartford Mutual Funds prior to 4 P.M. Eastern Time (3 P.M. Central Time) or the close of the New York Stock Exchange, whichever comes first. Any transaction on an account received after such time will receive the next business day’s offering price. For automated service 24 hours a day using your touch-tone phone, call 1-888-THE-STAG (843-7824). For your protection, telephone requests may be recorded in order to verify their accuracy. Proceeds from telephone transactions may be either mailed to the address of record, or sent electronically to a bank account on file. Also, for your protection, telephone redemptions are limited on accounts whose addresses have changed within the past 30 days. For circumstances in which you need to request to sell shares in writing, see “Selling Shares by Letter.”

· By Electronic Funds Transfer (EFT) or Wire — For Class A, Class B and Class C shares, fill out the “Bank Account or Credit Union Information” section of your new account application or the “Bank or Credit Union Information Form” to add bank instructions to your account. For Class Y shares, fill out the “Telephone Exchanges and Telephone Redemption” and “Bank Account or Credit Union Information” section of your new account application or call the transfer agent to request the forms to add the telephone redemption privilege to an existing account. Then, call the transfer agent to verify that the privilege is in place on your account. EFT transactions may be sent for amounts of $50 to $50,000. Amounts of $500 or more will be wired on the next business day and amounts of less than $500 may be sent by EFT or by check. Funds from EFT transactions are generally available by the third to fifth business day. Your bank may charge a fee for this service. Wire transfers are available upon request.

· By Letter — In certain circumstances, you will need to make your request to sell shares in writing. A check will be mailed to the name(s) and address in which the account is registered or otherwise according to your letter of

instruction, and overnight delivery may be requested for a nominal fee. To redeem, write a letter of instruction or complete a power of attorney indicating: the Fund name, the account number, the share class, the name(s) in which the account is registered, your date of birth, your residential address, your daytime phone number, your Social Security number, and the dollar value or the number of shares you wish to sell. Include all authorized signatures and obtain a Medallion signature guarantee if: you are requesting payment by check of more than $1,000 to an address of record that has changed within the past 30 days; you are selling more than $50,000 worth of shares; or you are requesting payment other than by check mailed to the address of record and payable to the registered owner(s). Mail the materials to your plan administrator or to the address below.

Exchanging Shares

You may exchange from one class of shares of the Fund for shares of the same class of any other Hartford Mutual Fund if such share class is available.

Call your plan administrator, financial intermediary, financial representative or the transfer agent at the number below to request an exchange, for any questions regarding exchanging shares, or to obtain a current prospectus for the Hartford Mutual Fund into which you are exchanging. If you are a Class A, Class B or Class C shareholder, you may also:

· Exchange shares on the web by clicking on “View Account Details” for the appropriate account, selecting “Exchange” from the “Select Action” menu next to the Hartford Mutual Fund you want to exchange from, and following the instructions on the Exchange Request pages to complete and submit the request.

· Write a letter of instruction indicating the fund names, share class, account number, the name(s) in which the accounts are registered, and your signature, and deliver these instructions to your financial representative or plan administrator, or mail or fax to the address listed below.

The registration for both accounts involved in the exchange must be identical and the minimum amount when exchanging Class A, Class B or Class C shares for a new Hartford Mutual Fund is $2,000 per fund ($5,000 for The Hartford Global All-Asset Fund and The Hartford Global Real Asset Fund) (except the minimum amount for Automatic Investment Plans is $250). You must retain at least $1000 in the Fund from which you exchange ($50 monthly Automatic Investment Plan). You may be subject to tax liability or sales charges as a result of your exchange (except for exchanges of Class R3, Class R4 or Class R5 shares).

The Fund reserves the right at any time in its sole discretion to amend or terminate the exchange privilege at any time, for any reason.

NOTE FOR RETIREMENT PLAN PARTICIPANTS AND INVESTORS WHOSE SHARES ARE HELD BY FINANCIAL REPRESENTATIVES

If you hold your shares through a retirement plan or if your shares are held with a financial representative you will need to make transactions through the retirement plan administrator or your financial representative. Some of the services and programs described in this prospectus may not be available or may differ in such circumstances. You should check with your retirement plan administrator or financial representative for further details.

Valuation of Shares

The net asset value per share (NAV) is determined for the Fund and each class of shares as of the close of regular trading on the New York Stock Exchange (the “Exchange”) (typically 4:00 p.m. Eastern Time, referred to as the “Valuation Time”) on each business day that the Exchange is open. The net asset value for each class

of shares is determined by dividing the value of the Fund’s net assets attributable to a class of shares by the number of shares outstanding for that class.

The Fund (references to the “Fund” in this section may relate, if applicable, to certain Underlying Funds) generally uses market prices in valuing portfolio securities. If market prices are not readily available or are deemed unreliable, the Fund will use the fair value of the security as determined in good faith under policies and procedures established by and under the supervision of that Fund’s Board of Directors. Market prices may be deemed unreliable, for example, if a security is thinly traded or if an event has occurred after the close of the security’s primary market, but before the close of the Exchange that is expected to affect the value of the portfolio security. The circumstances in which the Fund may use fair value pricing include, among others: (i) the occurrence of events that are significant to a particular issuer, such as mergers, restructuring or defaults; (ii) the occurrence of events that are significant to an entire market, such as natural disasters in a particular region or governmental actions; (iii) trading restrictions on securities; (iv) thinly traded securities and (v) market events such as trading halts and early market closings. In addition, with respect to the valuation of stocks primarily traded on foreign markets, the Fund uses a fair value pricing service approved by the Fund’s Board of Directors, which employs quantitative models that evaluate changes in the value of the foreign market proxies (for example, futures contracts, ADR’s, exchange traded funds) after the close of the foreign exchanges but before the Valuation Time. Securities that are primarily traded on foreign markets may trade on days that are not business days of the Fund. The value of the foreign securities in which the Fund invests may change on days when a shareholder will not be able to purchase or redeem shares of the Fund. Fair value pricing is subjective in nature and the use of fair value pricing by the Fund may cause the NAV of its shares to differ significantly from the NAV that would have been calculated using market prices at the close of the exchange on which a portfolio security is primarily traded but before the close of the Exchange. There can be no assurance that the Fund could obtain the fair value assigned to a security if the Fund were to sell the security at approximately the time at which the Fund determines its NAV. Securities of foreign issuers and non-dollar securities are translated from the local currency into U.S. dollars using prevailing exchange rates.

Exchange traded equity securities are valued at the last reported sale price or official close price on the exchange or market on which the security is primarily traded (the “Primary Market”) at the Valuation Time. If the security did not trade on the Primary Market, it may be valued at the Valuation Time at the last reported sale price on another exchange where it trades. The value of an equity security not traded on any exchange but traded on the Nasdaq Stock Market, Inc. or another over-the-counter market shall be valued at the last reported sale price or official closing price on the exchange or market on which the security is traded as of the Valuation Time.

Debt securities (other than short-term obligations and senior floating rate interests) held by the Fund are valued using bid prices or using valuations based on a matrix system (which considers factors such as security prices, yield, maturity and ratings) as provided by independent pricing services. Senior floating rate interests generally trade in over-the-counter (“OTC”) markets and are priced through an independent

pricing service utilizing independent market quotations from loan dealers or financial institutions. Securities for which prices are not available from an independent pricing service, may be valued using market quotations obtained from one or more dealers that make markets in the securities in accordance with procedures established by that Fund’s Board of Directors. Generally, the Fund may use fair valuation in regard to debt securities when the Fund holds defaulted or distressed securities or securities in a company in which a reorganization is pending. Short term investments with a maturity of more than 60 days when purchased are valued based on market quotations until the remaining days to maturity become less than 61 days. Investments that mature in 60 days or less are generally valued at amortized cost, which approximates market value.

For additional information regarding particular types of investments, please see the “Determination of Net Asset Value” section of the SAI.

Buy and Sell Prices

When you buy shares, you pay the NAV plus any applicable sales charges. When you sell shares, you receive the NAV less any applicable sales charges.

Execution Of Requests

The Fund is open on those days when the Exchange is open, typically Monday through Friday. Buy and sell requests are executed at the next NAV calculated after your request is received, if your order is in “good order” (has all required information), by the transfer agent, authorized broker-dealers or their authorized designee, or third-party administrators.

You may buy and sell shares of the Fund on the web, by telephone, by wire or by mail. You may exchange your shares by telephone, on the web, or by mail. Note that requests to buy, sell or exchange shares by mail must be sent to the P.O. Box at the address provided elsewhere in this Prospectus and will be sent from that address to the transfer agent for processing. Your request will be priced at the next NAV calculated after the transfer agent receives the request rather than after the request arrives at the P.O. Box.

At times of peak activity, it may be difficult to place requests by phone. During these times, visit www.hartfordmutualfunds.com or consider sending your request in writing.

In unusual circumstances, the Fund may temporarily suspend the processing of sell requests, or may postpone payment of redemption proceeds for up to seven days. The Fund may suspend the right of redemption for longer than seven days only as allowed by federal securities laws.

Requests In “Good Order”

All purchase and redemption requests must be received by the Fund in “good order.” This means that your request must include:

· Name, date of birth, residential address, and social security number.

· The Fund name, share class and account number.

· The amount of the transaction (in dollars or shares).

· Signatures of all owners exactly as registered on the account (for mail requests).

· Medallion signature guarantee or Signature Validation Program stamp (if required).

· Any supporting legal documentation that may be required.

Frequent Purchases and Redemptions of Fund Shares

The Hartford Mutual Funds are intended to be long-term investment vehicles and are not designed to provide investors with a means of speculating on short-term market movements (market timing). Frequent purchases and redemptions of Fund shares by the Fund’s shareholders can disrupt the management of the Fund, negatively affect the Fund’s performance, and increase expenses for all Fund shareholders. In particular, frequent trading (i) can force the Fund’s portfolio manager to hold larger cash positions than desired instead of fully investing all the Fund’s assets, which can result in lost investment opportunities; (ii) can cause unplanned and inopportune portfolio turnover in order to meet redemption requests; (iii) can increase broker-dealer commissions and other transaction costs as well as administrative costs for the Fund; and (iv) can trigger taxable gains for other shareholders. Also, some frequent traders engage in arbitrage strategies, by which these traders seek to exploit pricing anomalies that can occur when a Fund invests in securities that are thinly traded (for example, some high yield bonds and small capitalization stocks) or are traded primarily in markets outside of the United States. Frequent traders, and in particular those using arbitrage strategies, can dilute the Fund’s NAV for long-term shareholders.

If you intend to trade frequently or use market timing investment strategies, you should not purchase the Hartford Mutual Funds.

The Boards of Directors of the Hartford Mutual Funds have adopted policies and procedures with respect to frequent purchases and redemptions of Fund shares by Fund shareholders. The Hartford Mutual Funds’ policy is to discourage investors from trading in the Funds’ shares in an excessive manner that would be harmful to long-term investors and to make reasonable efforts to detect and deter excessive trading. Each Fund reserves the right to reject any purchase order at any time and for any reason, without prior written notice. Each Fund also reserves the right to revoke the exchange privileges of any person at any time and for any reason. In making such determinations, a Fund may consider an investor’s trading history in any of the Hartford Mutual Funds, including the person’s trading history in any accounts under a person’s common ownership or control.

It is the policy of the Funds to permit only two “substantive round trips” by an investor within any single Hartford Mutual Fund within a 90-day period.

A substantive round trip is a purchase of or an exchange into a Hartford Mutual Fund and a redemption of or an exchange out of the same Hartford Mutual Fund in a dollar amount that the Fund’s transfer agent determines, in the reasonable exercise of its discretion, could adversely affect the management of the Fund. When an additional transaction request for the Fund is received within the 90-day period, the requested transaction shall be rejected (unless such exchange or purchase already occurred) and the person requesting such transaction shall be

deemed an “Excessive Trader.” All exchange and purchase privileges of an Excessive Trader shall be suspended within such Fund for the first violation of the policy for a period of 90 days. For a second violation of the policy, the exchange and purchase privileges of the Excessive Trader shall be suspended indefinitely. If an Excessive Trader makes exchanges through a registered representative, in appropriate circumstances the Fund’s transfer agent may terminate the registered representative’s exchange and purchase privileges in the Hartford Mutual Funds. Automatic programs offered by the Funds such as dollar cost averaging and dividend diversification are exempt from the policy described above. In addition, the Money Market Fund is excluded from the policy.

The Hartford Mutual Funds’ policies for deterring frequent purchases and redemptions of Fund shares by a Fund shareholder are intended to be applied uniformly to all Fund shareholders to the extent practicable. Some financial intermediaries, such as broker-dealers, investment advisors, plan administrators, and third-party transfer agents, however, maintain omnibus accounts in which they aggregate orders of multiple investors and forward the aggregated orders to the Funds. Because the Funds receive these orders on an aggregated basis and because these omnibus accounts may trade with numerous fund families with differing market timing policies, the Funds are limited in their ability to identify or deter Excessive Traders or other abusive traders. The Hartford Mutual Funds’ procedures with respect to omnibus accounts are as follows: (1) Where HASCO is provided individual shareholder level transaction detail on a daily basis, HASCO shall monitor the daily trade activity of individual shareholders and apply the Policy. (2) Where HASCO is not provided individual shareholder level transaction detail on a daily basis, HASCO shall monitor the accounts at an omnibus level and apply detection tools designed to determine whether shareholder transactions violating the Policy may be occurring. In such cases, HASCO shall request and evaluate individual shareholder level transaction detail and seek to impose restrictions in accordance with the Policy. The Funds’ ability to identify and deter frequent purchases and redemptions of a Fund’s shares through omnibus accounts is limited, and the Funds’ success in accomplishing the objectives of the policies concerning frequent purchases and redemptions of Fund shares in this context depends significantly upon the cooperation of the financial intermediaries. In addition to the foregoing, HASCO also employs a process for reviewing certain large transactions in the Funds and may restrict trading as a result of its review.

The use of fair value pricing can serve both to make the Hartford Mutual Funds less attractive to market timers and to reduce the potential adverse consequences to other investors of market timing or abusive trading. Certain market timers seek to take advantage of pricing anomalies that can occur in Fund shares resulting from the manner in which the NAV of the Funds’ shares is determined each day. Frequent trading in Fund shares can dilute the value of long-term shareholders’ interests in a Fund if the Fund calculates its NAV using closing prices that are no longer accurate. This can happen particularly in Funds that invest in overseas markets or that invest in securities of smaller issuers or thinly traded securities. The Hartford Mutual Funds’ pricing procedures, particularly those procedures governing the determination of the “fair value” of securities for which market prices

are not readily available (or are unreliable) for foreign securities may serve as a deterrent against harmful excessive trading in fund shares. For additional information concerning the Hartford Mutual Funds’ fair value procedures, please refer to “Valuation of Shares.”

Certificated Shares

Shares are electronically recorded and, therefore, share certificates are not issued.

Account Closings

There may be instances in which it is appropriate for your shares to be redeemed and your account to be closed. For additional information about when your shares may be redeemed and your account closed, please see the SAI under “Account Closings.”

Sales In Advance of Purchase Payments

When you place a request to sell shares for which the purchase money has not yet been collected, the request will be executed in a timely fashion, but the Fund will not release the proceeds to you until your purchase payment clears. This may take up to 10 calendar days after the purchase.

Special Redemptions

Although it would not normally do so, the Fund has the right to pay the redemption price of shares of the Fund in whole or in part in portfolio securities constituting the shareholder’s proportionate share of the current assets of the Fund rather than cash. When the shareholder sells portfolio securities received in this fashion, a brokerage charge would be incurred. Any such securities would be valued for the purposes of making such payment at the same value as used in determining the Fund’s net asset value. The Fund, however, always redeems shares solely in cash up to the lesser of $250,000 or 1.00% of the net asset value of the Fund during any 90 day period for any one account.

Payment Requirements — Class A, Class C and Class Y

All of your purchases must be made in U.S. dollars and checks must be drawn on U.S. banks and made payable to The Hartford Mutual Funds. You may not purchase shares with a starter or third party check.

If your check does not clear, your purchase will be canceled and you will be liable for any losses or fees that the Fund or HIFSCO has incurred.

Certain broker-dealers and financial institutions may enter confirmed purchase orders with the Fund on behalf of customers, by phone or other electronic means, with payment to follow within the customary settlement period. If payment is not received by that time, the order will be canceled and the broker-dealer or financial institution will be held liable for the resulting fees or losses.

Account Statements

Class A Class B, Class C and Class Y — In general, you will receive account statements as follows:

· after every transaction (except certain automatic payment and redemption arrangements and dividend or distribution reinvestment) that affects your account balances

· after any changes of name or address of the registered owner(s)

· in all other circumstances, every quarter during which there is activity in your account, and at least annually

Every year you will also receive the appropriate tax reporting forms for the type of account you choose and the activity in your account.

If, however, you are a participant in an employer-sponsored retirement plan or you hold your shares in the name of your broker, you will receive statements from your plan administrator or broker pursuant to their policies.

Class I — You will receive account and tax information statements, if applicable, from your financial intermediary pursuant to its policies or from the transfer agent.

Class R3, Class R4 and Class R5 — You will receive statements and applicable tax forms from your plan administrator or broker pursuant to their policies.

Additional Investor Services — Class A, Class B and Class C

· Electronic Transfers Through Automated Clearing House (ACH) allow you to initiate a purchase or redemption for as little as $50 or as much as $50,000 between your bank account and Fund account using the ACH network. Sales charges and initial purchase minimums apply.

· Automatic Investment Plan (AIP) lets you set up regular investments from your bank account to the Fund. You determine the frequency and amount of your investments, and you can terminate your program at any time. To establish, complete the appropriate parts of your account application, or if this is an IRA account, complete the Mutual Funds Automatic Investment form. If you are using AIP to open an account, you must invest a minimum initial investment of $250 into the Fund and invest a minimum of $50 per month into the Fund.

· Systematic Withdrawal Plan may be used for routine bill payments or periodic withdrawals from your account. To establish, make sure you have at least $5,000 worth of shares in your account and that the amount per transaction is $50 or more. Also, make sure you are not planning to invest more money in this account (buying shares of the Fund during a period when you are also selling shares of the Fund is not advantageous to you, because of sales charges). Specify the payee(s), who may be yourself or any other party. There is no limit to the number of payees you may have. A Medallion signature guarantee is required if the payee is someone other than the registered owner. Determine the schedule (monthly, quarterly, semi-annually, annually or in certain selected months) and fill out the relevant part of the account application. To add a systematic withdrawal plan to an existing account, contact your financial representative or the transfer agent.

· Dollar Cost Averaging Programs (DCA) let you set up monthly or quarterly exchanges from the Fund to the same class of shares of another Hartford

FUND DISTRIBUTIONS AND TAX MATTERS

Dividends and Distributions

The Fund intends to distribute substantially all of its net investment income and capital gains to shareholders at least once a year. Capital gains of the Fund are normally declared and paid annually. Dividends from net investment income of the Fund are normally declared daily and paid monthly.

The Fund seeks to maintain a target rate of distribution for each month. In order to do so, the Fund may distribute less or more investment income than it earns on its investments each month. The Fund may use accrued undistributed investment income to fulfill distributions made during periods in which the Fund distributes more than the fund earns. Generally, distribution rates or yields from month to month may be impacted by accruals of undistributed income, changes in the Fund’s net asset value, changes in the number of accrual days, and adjustments for accounting purposes (including but not limited to changes in maturity dates of holdings and for currency gains or losses). The target rate of distribution is evaluated regularly and can change at any time. The target rate of distribution is not equivalent to the 30-day SEC yield of the Fund.

Dividends are paid on shares beginning on the business day after the day when the funds used to purchase your shares are collected by the transfer agent for this Fund. Notwithstanding the foregoing, the Company’s Board of Directors has delegated authority to the Fund’s Treasurer to reduce the frequency with which dividends are declared and paid and to declare and make payments of long-term capital gains as permitted or required by law or in order to avoid tax penalties. Further, the Fund reserves the right to change its dividend distribution policy at the discretion of the Board of Directors. Unless shareholders specify otherwise, all dividends and distributions received from the Fund are automatically reinvested in additional full or fractional shares of the Fund.

If you elect to receive dividends in cash, you will only receive a check if the dividend amount exceeds $10. If the dividend is $10 or less, the amount will automatically be reinvested in the Fund. If you would like to receive cash dividends, regardless of the amount, you can establish an electronic funds transfer to your bank. Please call the Fund for assistance in establishing electronic funds transfer transactions at 1-888-843-7824.

Taxability Of Dividends

Unless your shares are held in a tax-advantaged account, dividends and distributions you receive from the Fund, whether reinvested or taken as cash, are generally considered taxable. Distributions from the Fund’s long-term capital gains are taxable as long-term capital gains, regardless of how long you held your shares. Distributions from short-term capital gains and from ordinary income (other than certain qualified dividend income) are generally taxable as ordinary income. A portion of dividends from ordinary income may qualify for the dividends-received deduction for corporations. Distributions from certain qualified dividend income generally are taxable to individuals at the same rates that apply to long-term capital gains, if certain holding period and other requirements are met. The Fund does not

expect to generate significant amounts of income that qualifies for the dividends-received deduction or as qualified dividend income. The lower tax rates on qualified dividend income and long-term capital gains are currently scheduled to expire after 2012.

Some dividends paid in January may be taxable as if they had been paid the previous December.

Dividends and capital gains distributed by the Fund to tax-deferred retirement plan accounts are not taxable currently.

Taxability Of Transactions

Unless your shares are held in a tax-advantaged account, any time you sell or exchange shares, it is considered a taxable event for you. You may have a capital gain or a loss on the transaction that will be long-term or short-term, depending upon how long you held your shares. You are responsible for any tax liabilities generated by your transactions. See your tax advisor if you sell shares held for less than six months at a loss after receiving a long-term capital gain distribution from the Fund.

Exchanges within a tax-deferred retirement plan account will not result in a capital gain or loss for federal or state income tax purposes. With limited exceptions, distributions from a retirement plan account are taxable as ordinary income.

Additional Information

The Fund may be required to withhold U.S. federal income tax at the rate of 28% (currently scheduled to increase to 31% after 2012) of all taxable distributions payable to you if you fail to provide the Fund with your correct taxpayer identification number or to make required certifications, or if you have been notified by the IRS that you are subject to backup withholding. Backup withholding is not an additional tax. Any amounts withheld may be credited against your U.S. federal income tax liability. Non-resident aliens and other foreign shareholders will generally be subject to U.S. tax withholding on distributions paid from the Fund.

The Fund may be required to withhold U.S. federal income tax at the rate of 30% of all taxable distributions to you if you are a non-resident alien and there is no applicable tax treaty or if you are claiming reduced withholding under a tax treaty and you have not properly completed and signed the appropriate IRS Form W-8. You also must complete and send to us the appropriate IRS Form W-8 to certify your foreign status. Provided that the appropriate IRS Form W-8 is properly completed, long-term capital gains distributions and proceeds of sales are not subject to withholding for foreign shareholders.

Distributions from the Fund may also be subject to state, local and foreign taxes. You should consult your own tax advisor regarding the particular tax consequences of an investment in the Fund.

This section summarizes some of the consequences under current Federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the Fund under all applicable tax laws.

consideration to both yield and total return. The Fund normally invests at least 65% of its total assets in “investment grade” securities. The Fund may invest up to 35% of its total assets in bank loans or loan participation interests in secured or unsecured variable, fixed or floating rate loans to U.S. and foreign corporations, partnerships and other entities (“Bank Loans”). The Fund has an investment policy to invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, under normal circumstances, in fixed income securities, including Bank Loans; this policy may be changed by the Board without shareholder approval. In order to manage the Fund’s interest rate risk, generally the Fund will utilize interest rate swaps. The extent to which the Fund will utilize interest rate swaps depends on Hartford Investment Management’s view of the interest rate environment and general market conditions. Generally, if Hartford Investment Management expects interest rates to rise, the Fund will buy interest rate swaps to hedge the portion of its assets invested in fixed rate corporate bonds. A significant portion of the Fund’s assets could be exposed to the effects of and the risks associated with the Fund’s investments in interest rate swaps. The Fund normally will maintain a dollar weighted average duration of less than 3 years. Duration is a measure of the sensitivity of a fixed income security’s price to changes in interest rates. The Fund’s average duration measure incorporates a bond’s yield, coupon, final maturity, and the effect of interest rate swaps that may be used to manage the Fund’s interest rate risk. The use of an interest rate swap may have the effect of shortening the duration of a fixed income security. The Fund may invest up to 25% of its total assets in securities of foreign issuers, and may trade securities actively.

may also affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. There may be little trading in the secondary market for particular debt securities which may make them more difficult to value or sell.

Liquidity Risk — The risk that a particular investment may be difficult to purchase or sell and that the Fund may be unable to sell the investment at an advantageous time or price. Securities that are liquid at the time of purchase may later become illiquid due to events relating to the issuer of the securities, market events, economic conditions or investor perceptions. The value of illiquid securities may be lower than the market price of comparable liquid securities and thus negatively affect the Fund’s net asset value.

Mortgage- and Asset-Backed Securities Risk - Mortgage- and asset-backed securities represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. Mortgage-backed securities are subject to “prepayment risk” (the risk that borrowers will repay a loan more quickly in periods of falling interest rates) and “extension risk” (the risk that borrowers will repay a loan more slowly in periods of rising interest rates). If the Fund invests in mortgage-backed or asset-backed securities that are subordinated to other interests in the same mortgage pool, the Fund may only receive payments after the pool’s obligations to other investors have been satisfied. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may limit substantially the pool’s ability to make payments of principal or interest to the Fund, reducing the values of those securities or in some cases rendering them worthless. The risk of such defaults is generally higher in the case of mortgage pools that include so-called “subprime” mortgages.

Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

The Fund is subject to certain other risks, which are described elsewhere in this prospectus.

· Assume reinvestment of all dividends and distributions

· Would be lower if the Fund’s operating expenses had not been limited.

The bar chart:

· Shows how the Fund’s total return has varied from year to year

· Does not include the effect of sales charges. If sales charges were reflected in the bar chart, returns would have been lower

· Shows the returns of the Fund’s Class A shares. Because all of the Fund’s shares are invested in the same portfolio of securities, returns for the Fund’s other classes differ only to the extent that the classes do not have the same expenses.

Total returns by calendar year (excludes sales charges)

Highest/Lowest quarterly results during the periods shown in the bar chart were:

Highest 3.72% (2nd quarter, 2009) Lowest -1.68% (3rd quarter, 2008)

The Fund’s Class A Shares year-to-date return as of June 30, 2011 was 1.86%.

AVERAGE ANNUAL RETURNS. The table below shows returns for the Fund over time compared to those of a broad-based market index. After-tax returns, which are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes, are shown only for Class A shares and will vary for other classes. Returns prior to the inception date of certain

classes of shares may reflect returns of another class of shares. For more information regarding returns see the “Performance Notes” section in the Fund’s prospectus.

The return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

Actual after-tax returns, which depend on an investor’s particular tax situation, may differ from those shown and are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

ADDITIONAL INFORMATION REGARDING RISKS AND INVESTMENT STRATEGIES

INVESTMENT GOAL. The Fund seeks to provide current income and long-term total return.

PRINCIPAL INVESTMENT STRATEGY. The Fund seeks its goal by investing in securities that the sub-adviser, Hartford Investment Management Company (“Hartford Investment Management”), considers to be attractive giving consideration to both yield and total return. The Fund normally invests at least 65% of its total assets in “investment grade” securities. The Fund may invest up to 35% of its total assets in bank loans or loan participation interests in secured or unsecured variable, fixed or floating rate loans to U.S. and foreign corporations, partnerships and other entities (“Bank Loans”). The Fund has an investment policy to invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, under normal circumstances, in fixed income securities, including Bank Loans; this policy may be changed by the Board without shareholder approval. In order to manage the Fund’s interest rate risk, generally the Fund will utilize interest rate swaps. The extent to which the Fund will utilize interest rate swaps depends on Hartford Investment Management’s view of the interest rate environment and general market conditions. Generally, if Hartford Investment Management expects interest rates to rise, the Fund will buy interest rate swaps to hedge the portion of its assets invested in fixed rate corporate bonds. A significant portion of the Fund’s assets could be exposed to the effects of and the risks associated with the Fund’s investments in interest rate swaps. The Fund normally will maintain a dollar weighted average duration of less than 3 years. Duration is a measure of the sensitivity of a fixed income security’s price to changes in interest rates. The Fund’s average duration measure incorporates a bond’s yield, coupon, final maturity, and the effect of interest rate swaps that may be used to manage the Fund’s interest rate risk. The use of an interest rate swap may have the effect of shortening the duration of a fixed income security. The Fund may invest up to 25% of its total assets in securities of foreign issuers, and may trade securities actively.

Hartford Investment Management uses what is sometimes referred to as a top-down analysis to determine which sectors or industries may benefit or be harmed from current and future changes in the economy. Hartford Investment Management then selects individual securities to buy or sell from selected sectors and industries that, from a yield perspective, appear either attractive or unattractive. For individual securities, Hartford Investment Management assesses such factors as a company’s business environment, balance sheet, income statement, anticipated earnings and management team, and security structure.

Bonds in which the Fund invests include, but are not limited to, (1) securities issued or guaranteed as to principal or interest by the U.S. Government, its agencies or instrumentalities; (2) non-convertible and convertible debt securities issued or guaranteed by U.S. corporations or other issuers (including foreign issuers); (3) asset-backed and mortgage-related securities, including collateralized mortgage obligations; (4) securities and loans issued or guaranteed as to principal

or interest by a foreign issuer, including supranational entities such as development banks, non-U.S. corporations, banks or bank holding companies, or other foreign issuers; and (5) commercial mortgage-backed securities.

The Fund will invest in interest rate swaps to manage interest rate risk. The longer a security’s duration, the more sensitive it will generally be to changes in interest rates. Similarly, a fund with a longer average duration will generally be more sensitive to changes in interest rates than a fund with a shorter average duration. For example, a U.S. Treasury security with a duration of 2 years can be expected to change in price by approximately 2% for every 100 basis point change in the yield of the security.

In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate multiplied by a “notional principal amount,” in return for payments equal to a fixed rate multiplied by the same amount, for a specified period of time. The Fund usually enters into swaps on a net basis. The net amount of the excess, if any, of the Fund’s obligations over its entitlement with respect to each interest rate swap will be covered by an amount consisting of designated liquid assets having an aggregate net asset value at least equal to the accrued excess. If the Fund enters into a swap on other than a net basis, the Fund will designate the full amount of the Fund’s obligations under each such swap. If a default occurs by the other party to such transaction, the Fund will have contractual remedies pursuant to the agreements related to the transaction but such remedies may be subject to bankruptcy and insolvency laws which could affect the Fund’s rights as a creditor.

potential for a decline in the Fund’s income. These risks are greater during periods of rising inflation.

· Credit Risk - the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable to honor its financial obligation to the Fund.

· Currency Risk - the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment.

Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

Swaps Risk - The use of swaps is a highly specialized activity that involves investment techniques, risk analyses and tax planning different from those associated with ordinary portfolio securities transactions. The Fund’s transactions in swaps — which may involve a variety of reference assets — may be significant. These transactions can result in sizeable realized and unrealized capital gains and losses relative to the gains and losses from the Fund’s direct investments in the reference assets and short sales.

Foreign Investments Risk - Investments in foreign securities may be riskier than investments in U.S. securities. Foreign investments may be affected by the following:

· changes in currency rates

· changes in foreign or U.S. law or restrictions applicable to such investments and in exchange control regulations

· decreased liquidity

· substantially less volume on foreign stock markets and other securities markets

· higher commissions and dealer mark-ups

· inefficiencies in certain foreign clearance and settlement procedures that could result in an inability to execute transactions

· less uniform accounting, auditing and financial reporting standards

· less publicly available information about a foreign issuer or borrower

· less government regulation

· unfavorable foreign tax laws

· political or social instability or diplomatic developments in a foreign country

· differences in individual foreign economies.

· Governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth.

addition, adjustable and fixed rate mortgage-backed securities are subject to “prepayment risk.” When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of a fund because the Fund may have to reinvest that money at lower prevailing interest rates. The Fund’s investments in other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as additional risks associated with the nature of the assets and the servicing of those assets.

U.S. Government Securities Risk - Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Obligations of U.S. Government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

The maximum potential liability of the issuers of some U.S. Government securities held by the Fund may greatly exceed their current resources, including their legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.

The Fund is subject to certain additional risks, which are discussed below.

Additional Risks and Investment Information.

Floating Rate Loans Risk - A floating rate loan may not be fully collateralized which may cause the floating rate loan to decline significantly in value. Floating rate loans generally are subject to restrictions on resale. Floating rate loans sometimes trade infrequently in the secondary market. As a result, valuing a floating rate loan can be more difficult, and buying and selling a floating rate loan at an acceptable price can be more difficult or delayed. Difficulty in selling a floating rate loan can result in a loss.

Sovereign Debt Risk - Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.

market. Some countries have pervasive corruption and crime that may hinder investments. Certain emerging markets may also face other significant internal or external risks, including the risk of war, and ethnic, religious and racial conflicts. In addition, governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth. Emerging markets may also have differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments. Sometimes, they may lack or be in the relatively early development of legal structures governing private and foreign investments and private property. In addition to withholding taxes on investment income, some countries with emerging markets may impose differential capital gains taxes on foreign investors.

Fund of Funds Structure — Underlying Funds

Risks Related To The Fund Of Funds Structure For Underlying Funds:

· A fund-of-funds structure could increase or decrease gains and could affect the timing, amount and character of distributions to you from the fund for investments you make directly in the fund.

· Rebalancing Underlying Funds may increase transaction costs.

Other Investment Companies

· acquire more than 3% of the voting shares of any other investment company,

· invest more than 5% of a fund’s total assets in securities of any one investment company, and

· invest more than 10% of its total assets in securities of all investment companies.

ETFs: An investment in an ETF generally presents the following risks: the same primary risks as an investment in a fund that is not exchange-traded that has the same investment objectives, strategies and policies as the ETF; the risk that the ETF may fail to accurately track the market segment or index that underlies its investment objective; price fluctuation, resulting in a loss to the Fund; the risk that the ETF may trade at a price that is lower than its NAV; and the risk that an active market for the ETF’s shares may not develop or be maintained. The Fund will indirectly pay a proportional share of the asset-based fees of the ETFs in which the Fund invests. ETFs are also subject to specific risks depending on the nature of the ETF, such as liquidity risk, sector risk, and foreign and emerging market risk, as well as risks associated with fixed income securities, real estate investments and commodities. An investment in an ETF presents the risk that the ETF may no

longer meet the listing requirements of any applicable exchanges on which the ETF is listed.

About The Fund’s Investment Goal

Consequences of Portfolio Trading Practices

Investment Policies

The Fund has a name which suggests a focus on a particular type of investment. In accordance with Rule 35d-1 under the 1940 Act, the Fund has adopted a policy that it will, under normal circumstances, invest at least 80% of the value of its assets (net assets plus the amount of any borrowings for investment purposes) in investments of the type suggested by its name, as set forth in the Fund’s Principal Investment Strategy section. This requirement is applied at the time the Fund invests its assets. If, subsequent to an investment by the Fund, this requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this requirement. In addition, in appropriate circumstances, synthetic investments may count toward the 80% minimum if they have economic characteristics similar to the other investments included in the basket. The Fund’s policy to invest at least 80% of its assets in such a manner is not a “fundamental” one, which means that it may be changed without the vote of a majority of the Fund’s outstanding shares as defined in the 1940 Act. The name of the Fund may be changed at any time by a vote of the Fund’s Board of Directors. Shareholders will be given written notice at least 60 days prior to any change by the Fund of its 80% investment policy covered by Rule 35d-1.

Additional Investment Strategies and Risks

The Fund may invest in various securities and engage in various investment techniques that are not the principal focus of the Fund and, therefore, are not described in this prospectus. These securities and techniques, together with their risks, are discussed in the Fund’s Combined Statement of Additional Information

(3) No automatic conversion to Class A shares, so annual expenses continue at the Class C level throughout the life of your investment.

How Sales Charges Are Calculated

Class A sales charges and commissions paid to dealers for the Fund are as follows. The offering price includes the front-end sales load.

YOUR INVESTMENT	As a % of Offering Price		As a % of Net Investment		Dealer Commission-As Percentage of Offering Price
Less than $250,000	2.00	%	2.04	%	1.50	%
$250,000 — $499,999	1.50	%	1.52	%	1.00	%
$500,000 or more(1)	0	%	0	%	See below

(1) Investments of $500,000 or more in Class A shares may be made with no front-end sales charge. However, there is a contingent deferred sales charge (CDSC) of 1.00% on any Class A shares sold within 18 months of purchase. For purposes of this CDSC, all purchases made during a calendar month are counted as having been made on the first day of that month. The CDSC is based on the lesser of the original purchase cost or the current market value of the shares being sold and is not charged on shares you acquired by reinvesting your dividends and capital gains distributions. To keep your CDSC as low as possible, each time you place a request to sell shares we will first sell any shares in your account that are not subject to a CDSC.

a hypothetical and is not intended to represent the value of any Hartford Mutual Fund.

The distributor may pay up to the entire amount of the sales commission to particular broker-dealers. The distributor may pay dealers of record commissions on purchases over $500,000 in an amount of up to 1.00% of the first $4 million, plus 0.50% of the next $6 million, plus 0.25% of share purchases over $10 million or of purchases in any amount by adviser-sold donor-advised funds. This commission schedule may also apply to certain sales of Class A shares made to investors that qualify under any of the last four categories listed under “Waivers for Certain Investors.”

For retirement plans established on or after March 1, 2007, the commission schedule and 1.00% CDSC will not apply.

YEARS AFTER PURCHASE	CDSC
1st year	5.00	%
2nd year	4.00	%
3rd year	3.00	%
4th year	3.00	%
5th year	2.00	%
6th year	1.00	%
After 6 years	None

Class C sales charges are listed below. There is no CDSC on shares acquired through reinvestment of dividends and capital gains distributions. The CDSC is based on the original purchase cost or the current market value of the shares being sold, whichever is less. A front-end sales charge is not assessed on Class C shares.

YEARS AFTER PURCHASE	CDSC
1st year	1.00	%
After 1 year	None

DISTRIBUTION ARRANGEMENTS

Distribution Plans — Class A, Class B, Class C, Class R3 and Class R4 Shares

Class B Plan Pursuant to the Class B Plan, the Fund may pay HIFSCO a fee of up to 1.00% of the average daily net assets attributable to Class B shares, 0.75% of which is a fee for distribution financing activities and 0.25% of which is for shareholder account services. Effective January 1, 2011, 0.75% of the Class B shares’ Rule 12b-1 fee is being waived in accordance with FINRA rules, although it is possible that such fees may be charged in the future. As a result of this 12b-1 fee waiver, the Class B shares’ 12b-1 fee is 0.25% and the net operating expenses attributable to Class B shares are 0.85%. HIFSCO will advance to dealers the first-year service fee at a rate equal to 0.25% of the amount invested. As compensation for such advance, HIFSCO may retain the service fee paid by the Fund with respect

to such shares for the first year after purchase. Dealers will become eligible for additional service fees with respect to such shares commencing in the thirteenth month following purchase. Brokers may from time to time be required to meet certain other criteria in order to receive service fees. HIFSCO or its affiliates are entitled to retain all service fees payable under the Class B Plan for which there is no dealer of record or for which qualification standards have not been met as partial consideration for personal services and/or account maintenance services performed by HIFSCO or its affiliates for shareholder accounts. The Class B Plan also provides that HIFSCO will receive all contingent deferred sales charges attributable to Class B shares.

General Distribution fees paid to HIFSCO may be spent on any activities or expenses primarily intended to result in the sale of the Fund’s shares including: (a) payment of initial and ongoing commissions and other compensation payments to brokers, dealers, financial institutions or others who sell the Fund’s shares, (b) compensation to employees of HIFSCO, (c) compensation to and expenses, including overhead such as communications and telephone, training, supplies, photocopying and similar types of expenses, of HIFSCO incurred in the printing and mailing or other dissemination of all prospectuses and statements of additional information, (d) the costs of preparation, printing and mailing of reports used for sales literature and related expenses, i.e., advertisements and sales literature, and (e) other distribution-related expenses and for the provision of personal service and/or the maintenance of shareholder accounts. These Plans are considered compensation type plans, which means that the Fund pays HIFSCO the entire fee regardless of HIFSCO’s expenditures. Even if HIFSCO’s actual expenditures exceed the fee payable to HIFSCO at any given time, the Fund will not be obligated to pay more than that fee.

Payments to Financial Intermediaries and Other Entities

This section includes additional information about different types of compensation paid by HIFSCO and its affiliates to other entities with respect to the Hartford Mutual Funds.

Additional Payments may be used for various purposes and take various forms, such as:

· Payments for putting Hartford Mutual Funds on a Financial Intermediary’s list of mutual funds available for purchase by its customers;

· Provision of educational programs, including information and related support materials;

· Provision of computer hardware and software; and

Servicing Compensation to Servicing Intermediaries. HIFSCO and its affiliates pay Servicing Intermediaries compensation for sub-accounting, administrative and/or shareholder processing services (“Servicing Payments”). These Servicing Payments may cause a Servicing Intermediary to choose to provide services to the Hartford Mutual Funds rather than to other investments products for which it may receive a lower payment.
