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 Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 42.27% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests in a diversified portfolio of stocks (substantially dividend paying) and debt securities. The Fund normally invests at least 25% of its total assets in debt securities, including bonds, notes, debentures and money market securities. In addition, the Fund normally invests at least 25% of

<br>  <br> www.franklintempleton.com Summary Prospectus 3

------

FRANKLIN MANAGED INCOME FUND<br>SUMMARY PROSPECTUS

its total assets in equity securities, primarily common and preferred stock. To the extent that the value of convertible and preferred securities can be attributed to their debt characteristics, they will be treated as debt securities for purposes of this investment policy.

The Fund seeks income by investing in a combination of fixed or floating rate corporate, agency and government bonds issued in the United States and other countries, as well as common stocks of companies in any market capitalization range and convertible securities. The Fund seeks capital appreciation by investing in equity securities and convertible securities of companies from a variety of industries.

The Fund generally invests in investment grade debt securities. The Fund may invest in debt securities of any duration. The Fund does not currently anticipate investing more than 25% of its total assets in securities of issuers domiciled outside the United States.

The Fund also invests in equity-linked notes, which are hybrid derivative-type instruments that are specially designed to combine the characteristics of one or more reference securities (usually a single stock, a stock index or a basket of stocks (underlying securities)) and a related equity derivative, such as a put or call option, in a single note form.

The Fund may, from time to time, use (i) equity-related derivatives, which may include call and put options on equity securities and equity security indices, futures on equity securities and equity indexes and options on equity index futures, (ii) interest rate derivatives, including interest rate swaps and interest rate/bond futures contracts, (iii) currency derivatives, including forward foreign currency exchange contracts, currency futures contracts, currency swaps and currency options and (iv) credit-related derivatives, such as credit default swaps and options on credit default swaps for various purposes, including enhancing Fund returns, increasing liquidity, gaining exposure to particular instruments or markets in more efficient or less expensive ways and/or hedging risks. The use of such derivative transactions may allow the Fund to obtain net long or net short exposures to selected securities, markets, interest rates, countries, currencies, credits or durations.

The investment manager applies a "bottom-up" approach to investing in individual securities. The investment manager will assess the market price of a company's securities relative to the investment manager's evaluation of the company's long-term earnings, asset value and cash flow potential. The investment manager also considers a company's price/earnings ratio, profit margins and liquidation value. In determining an optimal mix of equity and fixed-income investments for the Fund, the investment manager assesses changing economic, market and industry conditions.

<br>  <br> 4 Summary Prospectus www.franklintempleton.com

------

FRANKLIN MANAGED INCOME FUND<br>SUMMARY PROSPECTUS

Under normal market conditions, the Fund employs a managed distribution policy that is designed to provide shareholders with regular distributions from their investment. Under this policy, the Fund distributes twelve level monthly payments throughout each calendar year to enable shareholders to estimate the distributions they will receive from the Fund; however, the twelfth monthly payment may be greater than the initially anticipated amount if additional income or capital gains are required to be distributed. The targeted annual payout rate for all share classes is between approximately 2.75% and 6.25% per share based on the last net asset value of the Fund of the prior calendar year in which the distribution is being made (e.g., for distributions made in 2025, the targeted annual payout rate for all share classes will be based on the Fund's net asset value on December 31, 2024). The distribution rate will vary by class based on the expenses of each class. Every year, the investment manager will undertake to determine if an adjustment should be made to the monthly rate.

It is possible to lose money by investing in the Fund notwithstanding the managed distribution policy. There can be no assurance or guarantee that the Fund will provide a fixed stable level of distributions at any time or over any period of time. An investment in the Fund could lose money over short, intermediate, or even long periods of time.

Principal Risks

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

**Market:** The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund's investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest, inflation or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in additional tariffs, trade barriers and/or investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economic prospects of

<br>  <br> www.franklintempleton.com Summary Prospectus 5

------

FRANKLIN MANAGED INCOME FUND<br>SUMMARY PROSPECTUS

many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

**Credit:** An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value.

**Interest Rate:** When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.

**Equity-Linked Notes (ELNs):** Investments in ELNs often have risks similar to their underlying securities or index, which could include management risk, market risk and, as applicable, foreign securities and currency risks. In addition, since ELNs are in note form, ELNs are also subject to certain debt securities risks, such as interest rate and credit risks. Should the prices of the underlying securities or index move in an unexpected manner, the Fund may not achieve the anticipated benefits of an investment in an ELN, and may realize losses, which could be significant and could include the Fund's entire principal investment. An investment in an ELN is also subject to counterparty risk, which is the risk that the issuer of the ELN will default or become bankrupt and the Fund will have difficulty being repaid, or fail to be repaid, the principal amount of, or income from, its investment. Investments in ELNs are also subject to liquidity risk, which may make ELNs difficult to sell and value. In addition, ELNs may exhibit price behavior that does not correlate with their underlying securities, index or a fixed-income investment.

**Convertible Securities:** Convertible securities are subject to the risks of stocks when the underlying stock price is high relative to the conversion price (because more of the security's value resides in the conversion feature) and debt securities when the underlying stock price is low relative to the conversion price (because the conversion feature is less valuable). The value of convertible securities may rise and fall with the market value of the underlying stock or, like a debt security, vary with changes in interest rates and the credit quality of the issuer. A convertible security is not as sensitive to interest rate changes as a similar non-convertible debt security, and generally has less potential for gain or loss than the underlying stock.

<br>  <br> 6 Summary Prospectus www.franklintempleton.com

------

FRANKLIN MANAGED INCOME FUND<br>SUMMARY PROSPECTUS

**Foreign Securities (non-U.S.):** Investing in foreign securities typically involves different risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations. The risks of investing in foreign securities are typically greater in less developed or emerging market countries.

**Derivative Instruments:** The performance of derivative instruments depends largely on the performance of an underlying instrument, such as a currency, security, interest rate or index, and such instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs and can create economic leverage in the Fund's portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that exceeds the Fund's initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative instrument, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security, interest rate index or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.

**Focus:** To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investments from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

**Managed Distribution Policy:** The Fund's monthly payments under the managed distribution policy may reduce the amount of assets available for investment by the Fund, even if the Fund's assets grow over time. In addition, the Fund may return capital to shareholders (i.e., a return of all or part of a shareholder's original investment). Fund shareholders are expected to receive a monthly distribution that is equal to a set percentage per share, which will be different per class based on differences in class expenses, multiplied by the number of shares owned on the record date; therefore, redemptions from a shareholder's account will reduce future distributions. The managed distribution policy is not designed to generate, and is not expected to result in, distributions that equal a fixed percentage of the Fund's current net asset value per share or a fixed percentage of a shareholder's current account value.

<br>  <br> www.franklintempleton.com Summary Prospectus 7

FRANKLIN MANAGED INCOME FUND<br>SUMMARY PROSPECTUS

**Management:** The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

**Cybersecurity:** Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing redeeming or exchanging or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

No one index is representative of the Fund's portfolio.

The figures in the average annual total returns table above reflect the Class A shares maximum front-end sales charge of 5.50%. Prior to September 10, 2018, Class A shares were subject to a maximum front-end sales charge of 5.75%. If the prior maximum front-end sales charge of 5.75% was reflected, performance for Class A shares in the average annual total returns table would be lower.

The after-tax returns presented in the table are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

Purchase and Sale of Fund Shares

You may purchase or redeem shares of the Fund on any business day online through our website at www.franklintempleton.com, by mail (Franklin Templeton Investor Services, P.O. Box 33030, St. Petersburg, FL 33733), or by telephone at (800) 632-2301. For Class A, C and R, the minimum initial purchase for most accounts is $1,000 (or $25 under an automatic investment plan). Class R6 and Advisor Class are only available to certain qualified investors and the minimum initial investment will vary depending on the type of qualified investor, as described under "Your Account — Choosing a Share Class — Qualified Investors — Class R6" and "— Advisor Class" in the Fund's prospectus. There is no minimum investment for subsequent purchases.

Taxes

The Fund's distributions are generally taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case your distributions would generally be taxed when withdrawn from the tax-advantaged account.

Due to the Fund's managed distribution policy, the Fund's monthly distributions may consist of a return of capital, which will have the effect of reducing your cost basis in the Fund's shares and thereby increasing the amount of capital gain, if any, or decreasing the amount of capital loss, if any, that you will realize when selling or exchanging Fund shares.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments
