(1)	A shareholder transacting in share classes without a front-end sales charge may be required to pay a commission to its financial intermediary. Please contact your financial intermediary for more information about whether such a commission may apply to your transaction.
(2)	A contingent deferred sales charge ("CDSC") of 1.00% may be assessed on certain Class A shares purchased or acquired without a sales charge if they are redeemed before the first day of the month in which the one-year anniversary of the purchase falls.
(3)	A CDSC of 1.00% may be assessed on Class C shares if they are redeemed before the first anniversary of their purchase.
(4)	The 12b-1 fee the Fund will pay on Class C shares will be a blended rate calculated based on (i) 1.00% of the Fund's average daily net assets attributable to shares held for less than one year and (ii) 0.80% of the Fund's average daily net assets attributable to shares held for one year or more. All Class C shareholders of the Fund will bear 12b-1 fees at the same rate.
(5)	For the period from May 1, 2024 through April 30, 2025, Lord Abbett Distributor LLC ("Lord Abbett Distributor") has contractually agreed to waive the Fund's 0.10% Rule 12b-1 fee for Class F shares. This agreement may be terminated only by the Fund's Board of Directors.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same, giving effect to the fee waiver and expense reimbursement arrangement described above. Class C shares automatically convert to Class A shares after eight years. The expense example for Class C shares for the ten-year period reflects the conversion to Class A shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 the 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 53% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

To pursue its objective, under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in debt securities that are tied economically to emerging market countries and derivative instruments that are intended to provide economic exposure to such securities. For purposes of this policy, the Fund considers emerging market countries to include every nation in the world except the United States, Canada, Japan, Australia, New Zealand, and most countries located in Western Europe.

The Fund may invest in all types of debt securities and derivative instruments, including, among others, corporate debt securities, government securities (including sovereign and quasi-sovereign bonds), loans, convertible securities, mortgage-related and other asset-backed securities, inflation-linked investments, structured notes, hybrid or "indexed" securities, event-linked bonds, and derivatives based on the return of debt securities. The Fund may invest in derivatives, consisting principally of swaps, options, forwards, and futures, for hedging or non-hedging purposes as a substitute for investing directly in emerging market debt securities.

The Fund may invest without limit in securities denominated in non-U.S. currencies.

The Fund may invest in securities of any credit quality, maturity, or duration. The Fund may invest without limitation in high-yield debt securities (commonly referred to as "below investment grade" or "junk" bonds). High-yield debt securities are rated

SUMMARY - Emerging Markets Bond Fund

BB/Ba or lower at the time of purchase by an independent rating agency, or are unrated but deemed by Lord, Abbett & Co. LLC ("Lord Abbett") to be of comparable quality.

The Fund's assets will be invested across different industries, sectors, countries, and regions. However, the Fund's portfolio management team may invest a significant percentage of the Fund's assets in issuers in a single industry, sector, country, or region.

The portfolio management team buys and sells securities using a relative value-oriented investment process and combines bottom-up and top-down analysis to construct its portfolio. In selecting securities, the portfolio management team may overweight or underweight individual issuers, industries, sectors, countries, or regions relative to the benchmark. In evaluating a particular country, the portfolio management team may evaluate the country's internal political, market, and economic factors, such as public finances, monetary policy, financial markets, foreign investment regulations, exchange rate policy and labor conditions, among others. The investment team may also consider the risks and return potential presented by environmental, social, and governance ("ESG") factors in investment decisions. The Fund may engage in active and frequent trading of its portfolio securities.

The Fund may sell a security when the Fund believes the security is less likely to benefit from the current market and economic environment, or shows signs of deteriorating fundamentals, among other reasons. The Fund may deviate from the investment strategy described above for temporary defensive purposes. The Fund may miss certain investment opportunities if defensive strategies are used and thus may not achieve its investment objective.

PRINCIPAL RISKS

As with any investment in a mutual fund, investing in the Fund involves risk, including the risk that you may receive little or no return on your investment. When you redeem your shares, they may be worth more or less than what you paid for them, which means that you may lose a portion or all of the money you invested in the Fund. The principal risks of investing in the Fund, which could adversely affect its performance, include:

·Portfolio Management Risk: If the strategies used and investments selected by the Fund's portfolio management team fail to produce the intended result, the Fund may suffer losses or underperform other funds with the same investment objective or strategies, even in a favorable market.

·Market Risk: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt securities.

SUMMARY - Emerging Markets Bond Fund

5

·Fixed Income Securities Risk: The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that issuers will fail to make timely payments of principal or interest or default altogether. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or general economic news than higher rated securities. In addition, as interest rates rise, the Fund's investments typically will lose value.

·Foreign and Emerging Market Company Risk: Investments in foreign companies and in U.S. companies with economic ties to foreign markets generally involve special risks. These companies may be more vulnerable to economic, political, and social instability and subject to less government supervision, lack of transparency, inadequate regulatory and accounting standards, and foreign taxes. Foreign company securities also include American Depositary Receipts ("ADRs"), which may be less liquid than the underlying shares in their primary trading market. Foreign securities also may subject the Fund's investments to changes in currency exchange rates. Emerging market securities generally are more volatile than other foreign securities, and are subject to greater liquidity, regulatory, and political risks. Investments in emerging markets may be considered speculative and generally are riskier than investments in more developed markets. Emerging markets are more likely to experience hyperinflation and currency devaluations. Securities of emerging market companies may have far lower trading volumes and less liquidity than securities of issuers in developed markets. Companies with economic ties to emerging markets may be susceptible to the same risks as companies organized in emerging markets.

·Foreign Currency Risk: Investments in securities that are denominated or receiving revenues in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline in value relative to the currency being hedged. Foreign currency exchange rates may fluctuate significantly over short periods of time.

·Derivatives Risk: The risks associated with derivatives may be different from and greater than the risks associated with directly investing in securities and other investments. Derivatives may increase the Fund's volatility and reduce its returns. Derivatives may not perform as expected and the Fund may not realize the intended benefits. Whether the Fund's use of derivatives is successful may depend on, among other things, the portfolio managers' ability to correctly forecast market movements, company and industry valuation levels and trends, changes in foreign exchange and interest rates, and other factors. If the portfolio managers incorrectly forecast these and other factors, the Fund's performance could suffer. In addition, given their complexity, derivatives are subject to the risk that improper or misunderstood documentation may expose the Fund to losses.

SUMMARY - Emerging Markets Bond Fund

·Convertible Securities Risk: Convertible securities are subject to the risks affecting both equity and fixed income securities, including market, credit, liquidity, and interest rate risk. Convertible securities tend to be more volatile than other fixed income securities, and the markets for convertible securities may be less liquid than markets for common stocks or bonds. A significant portion of convertible securities have below investment grade credit ratings and are subject to increased credit and liquidity risks.

·Sovereign Debt Risk: Sovereign debt securities are subject to the risk that the relevant sovereign government or governmental entity may delay or refuse to pay interest or repay principal on its debt. There is no legal process for collecting sovereign debt that is not repaid, nor are there bankruptcy proceedings through which all or part of the unpaid sovereign debt may be collected.

·Loan Risk: Investments in floating or adjustable rate loans are subject to increased credit and liquidity risks. Loan prices also may be adversely affected by supply-demand imbalances caused by conditions in the loan market or related markets. Below investment grade loans, like high-yield debt securities, or junk bonds, usually are more credit sensitive than interest rate sensitive, although the value of these instruments may be affected by interest rate swings in the overall fixed income market. Loans may be subject to structural subordination andmay be subordinated to other obligations of the borrower or its subsidiaries.

·Government Securities Risk: The Fund invests in securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities (such as the Government National Mortgage Association ("Ginnie Mae"), the Federal National Mortgage Association ("Fannie Mae"), or the Federal Home Loan Mortgage Corporation ("Freddie Mac")). Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government would provide financial support.

·Mortgage-Related and Other Asset-Backed Securities Risk: Mortgage-related securities, including commercial mortgage-backed securities ("CMBS") and other privately issued mortgage-related securities, and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates and economic conditions, including delinquencies and defaults.The prices of mortgage-related and other asset-backed securities, depending on their structure and the rate of payments, can be volatile. They are subject to prepayment risk (higher than expected prepayment rates of mortgage obligations due to a fall in market interest rates) and extension risk (lower than expected prepayment rates of mortgage obligations due to a rise in market interest rates). These risks increase the Fund's overall interest rate risk. Some mortgage-related securities

SUMMARY - Emerging Markets Bond Fund

receive government or private support, but there is no assurance that such support will remain in place.

·Commercial Mortgage-Backed Securities Risk: CMBS include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. Many of the risks of investing in CMBS reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. CMBS may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities.

·High Yield Securities Risk: High yield securities (commonly referred to as "junk" bonds) typically pay a higher yield than investment grade securities, but may have greater price fluctuations and have a higher risk of default than investment grade securities. The market for high yield securities may be less liquid due to such factors as interest rate sensitivity, negative perceptions of the junk bond markets generally, and less secondary market liquidity. This may make such securities more difficult to sell at an acceptable price, especially during periods of financial distress, increased market volatility, or significant market decline.

·Geographic Focus Risk: To the extent the Fund focuses its investments in a single country or only a few countries in a particular geographic region, economic, political, regulatory or other conditions affecting such region may have a greater impact on Fund performance.

·Leverage Risk: Certain of the Fund's transactions (including, among others, forward foreign currency contracts and other derivatives, reverse repurchase agreements, and the use of when-issued, delayed delivery or forward commitment transactions) may give rise to leverage risk. Leverage may increase volatility in the Fund by magnifying the effect of changes in the value of the Fund's holdings. The use of leverage may cause the Fund to lose more money in adverse environments than would have been the case in the absence of leverage. There is no assurance that the Fund will be able to employ leverage successfully.

·Credit Risk: Debt securities are subject to the risk that the issuer or guarantor of a security may not make interest and principal payments as they become due or may default altogether. In addition, if the market perceives a deterioration in the creditworthiness of an issuer, the value and liquidity of securities issued by that issuer may decline. To the extent that the Fund holds below investment grade securities, these risks may be heightened. Insured debt securities have the credit risk of the insurer in addition to the credit risk of the underlying investment being insured.

·Interest Rate Risk: As interest rates rise, prices of bonds (including tax-exempt bonds) generally fall, typically causing the Fund's investments to lose value.

SUMMARY - Emerging Markets Bond Fund

8

Additionally, rising interest rates or lack of market participants may lead to decreased liquidity in fixed income markets. Interest rate changes generally have a more pronounced effect on the market value of fixed-rate instruments, such as corporate bonds, than they have on floating rate instruments, and typically have a greater effect on the price of fixed income securities with longer durations. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy, rising inflation, and changes in general economic conditions.

·Liquidity/Redemption Risk: The Fund may lose money when selling securities at inopportune times to fulfill shareholder redemption requests. The risk of loss may increase depending on the size and frequency of redemption requests, whether the redemption requests occur in times of overall market turmoil or declining prices, and whether the securities the Fund intends to sell have decreased in value or are illiquid. The Fund may be less able to sell illiquid securities at its desired time or price. It may be more difficult for the Fund to value its investments in illiquid securities than more liquid securities.

·Potential Changes in Tax Treatment Risk: The Fund intends to continue to qualify as a "regulated investment company" under subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). Under subchapter M, at least 90% of the Fund's gross income for each taxable year must be "qualifying income." The Fund believes that its investment strategies with respect to foreign currencies will generate qualifying income under current U.S. federal income tax law. The Code expressly provides the U.S. Treasury Department with authority to issue regulations that would exclude foreign currency gains from qualifying income under certain circumstances. As of the date of this prospectus, the U.S. Treasury Department has not exercised this regulatory authority; however, there can be no assurance that it will not issue regulations in the future (possibly with retroactive effect) that would treat some or all of the Fund's foreign currency gains as nonqualifying income.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. For more information on the principal risks of the Fund, please see the "More Information About the Funds - Principal Risks" section in the prospectus.

PERFORMANCE

The bar chart and table below provide some indication of the risks of investing in the Fund by illustrating the variability of the Fund's returns. Each assumes reinvestment of dividends and distributions. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. No performance is shown for Class P and R2 shares because the Fund has no Class P and R2 shares outstanding. Class P and R2 shares of the Fund are not currently offered.

The bar chart shows changes in the performance of the Fund's Class A shares from calendar year to calendar year. This chart does not reflect the sales charge applicable to Class A shares. If the sales charge were reflected, returns would be lower. Performance for the Fund's other share classes will vary due to the different expenses each class bears. Updated performance information is available at www.lordabbett.com or by calling 888-522-2388.

The Fund implemented its present investment strategy effective August 1, 2018. Performance for earlier periods reflects the Fund's prior investment strategy.

The table below shows how the Fund's average annual total returns compare to the returns of a securities market index with investment characteristics similar to those of the Fund as well as to a broad-based securities market index.¹ The Fund's average annual total returns include applicable sales charges.

The after-tax returns of Class A shares included in the table below are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. In some cases, the return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to a tax benefit resulting from realized losses on a sale of Fund shares at the end of the period that is used to offset other gains. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements such as 401(k) plans or Individual Retirement Accounts ("IRAs"). After-tax returns for other share classes are not shown in the table and will vary from those shown for Class A shares.

¹The Fund has adopted the Bloomberg U.S. Aggregate Bond Index as its broad-based securities market index.
