To earn a high level of current income. A secondary goal is capital appreciation over the long term.

These tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees (including on Class R6 and Advisor Class shares), such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $100,000 in Franklin Templeton funds and certain other funds distributed through Franklin Distributors, LLC, the Fund’s distributor. More information about these and other discounts is available from your financial professional and under “Your Account” on page 51 in the Fund’s Prospectus and under “Buying and Selling Shares” on page 88 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in Appendix A – “Intermediary Sales Charge Discounts and Waivers” to the Fund’s prospectus.

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 349.54% of the average value of its portfolio. If mortgage dollar roll transactions had been excluded, the Fund's portfolio turnover rate for the most recent fiscal year would have been 156.76% of the average value of its portfolio.

Under normal market conditions, the Fund invests at least 80% of its net assets in bonds, including derivative instruments or other investments that have economic characteristics similar to bonds.

The Fund may invest in U.S. and foreign debt securities, including those in emerging markets. Debt securities include all varieties of fixed, variable and floating rate income securities, including bonds, U.S. and foreign government and agency securities, corporate loans (and loan participations) and mortgage-backed securities and other asset-backed securities. The Fund shifts its investments among various classes of debt securities and at any given time may have a substantial amount of its assets invested in any class of debt security.

The Fund follows a core plus strategy, which means it invests primarily in investment-grade securities, but also may invest up to 20% of its assets in below investment grade securities to potentially increase returns. The below-investment grade debt securities in which the Fund invests are generally rated at least Caa by Moody's Ratings (Moody's) or CCC by S&P Global Ratings (S&P) or are unrated securities the Fund's investment manager determines are of comparable quality.

The Fund targets an estimated average portfolio duration, under normal market conditions, of within one and a half years of the average portfolio duration of the Fund’s benchmark, the Bloomberg US Aggregate Index. As of July 31, 2026, the average portfolio duration of the Bloomberg US Aggregate Index was 5.9 years.

The Fund may invest in many different securities issued or guaranteed by the U.S. government or by non-U.S. governments, or their respective agencies or instrumentalities, including mortgage-backed securities and inflation-indexed securities issued by the U.S. Treasury. Mortgage-backed securities represent an interest in a pool of mortgage loans made by banks and other financial institutions to finance purchases of homes, commercial buildings and other real estate. The individual mortgage loans are packaged or "pooled" together for sale to investors.

As the underlying mortgage loans are paid off, investors receive principal and interest payments. These securities may be fixed-rate or adjustable-rate mortgage-backed securities (ARMS). The Fund may purchase or sell mortgage-backed securities on a delayed delivery or forward commitment basis through the "to-be-announced" (TBA) market. With TBA transactions, the particular securities to be delivered must meet specified terms and standards. The Fund may also invest in collateralized mortgage obligations (CMOs) and a small portion of its assets directly in mortgage loans.

For purposes of pursuing its investment goals, the Fund regularly enters into various currency-related transactions involving derivative instruments, including currency and cross currency forwards, currency swaps, currency and currency index futures contracts and currency options. The Fund regularly enters into interest rate and credit-related transactions involving derivative instruments, including interest rate, fixed income total return and credit default swaps and interest rate and/ or bond futures contracts. The use of these derivative transactions may allow the Fund to obtain net long or net short exposures to selected currencies, interest rates, countries, durations or credit risks. These derivative instruments may also be used for hedging purposes, to enhance Fund returns or to obtain exposure to various market sectors. The Fund’s investments in derivative instruments and other investments that provide exposure to the investment focus indicated in the Fund’s 80% policy, or that provide exposure to one or more market risk factors associated with the investment focus indicated in the Fund’s name, are included in the Fund’s 80% basket.

The Fund may invest a significant portion of its assets in complex fixed income securities, such as collateralized debt obligations (CDOs), which are generally a type of asset-backed securities. The Fund's investments in CDOs may include investments in collateralized loan obligations (CLOs), which are a type of CDO.

The Fund's investment manager is a research driven, fundamental investor that relies on a team of analysts to provide in-depth industry expertise and uses both qualitative and quantitative analysis to evaluate issuers. The Fund uses an active asset allocation strategy to try to achieve its investment goals. The investment manager uses a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to try to take advantage of varying sector reactions to economic events.

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.

High-Yield Debt Instruments: Issuers of lower-rated or “high-yield” debt instruments (also known as “junk bonds”) are not as strong financially as those issuing higher credit quality debt instruments. High-yield debt instruments are generally considered predominantly speculative by the applicable rating agencies as their issuers are more likely to encounter financial difficulties because they may be more highly leveraged, or because of other considerations. In addition, high yield debt instruments generally are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high-yield debt instruments generally fluctuate more than those of higher credit quality. High-yield debt instruments are generally more illiquid (harder to sell) and harder to value.

Mortgage Securities and Asset-Backed Securities: Mortgage securities differ from conventional debt securities because principal is paid back periodically over the life of the security rather than at maturity. The Fund may receive unscheduled payments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. Because of prepayments, mortgage securities may be less effective than some other types of debt securities as a means of "locking in" long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. A reduction in the anticipated rate of principal prepayments, especially during periods of rising interest rates, may increase or extend the effective maturity and duration of mortgage securities, making them more sensitive to interest rate changes, subject to greater price volatility, and more susceptible than some other debt securities to a decline in market value when interest rates rise. Mortgage securities purchased on a delayed delivery or forward commitment basis through the TBA (to-be-announced) market are subject to the risk that the actual securities received by the Fund may be less favorable than anticipated, or that a counterparty will fail to deliver the security.

Issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. Like mortgage securities, asset-backed securities are subject to prepayment and extension risks.

Income: The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.

Foreign Securities (non-U.S.): Investing in foreign securities typically involves different risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; diplomatic and political developments could affect the economies, industries, and securities and currency markets of the countries in which the Fund is invested, which can include rapid and adverse political changes; social instability; regional conflicts; sanctions imposed by the United States, other nations or other governmental entities, including supranational entities; terrorism; and war; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency.

Emerging Market Countries: The Fund’s investments in securities of issuers in emerging market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

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.

Inflation: The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund. Debt securities that pay a

fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate debt securities may be able to participate, over the long term, in rising interest rates which have historically corresponded with long-term inflationary trends.

Liquidity: The trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.

Portfolio Turnover: Active and frequent trading may increase a shareholder’s tax liability and the Fund’s transaction costs, which could detract from Fund performance.

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 shares 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 (including the development of artificial intelligence and machine learning), 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. The rapid development and increasingly widespread use of artificial intelligence technologies could increase the effectiveness of cyber attacks and exacerbate the risks.
