Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund seeks to achieve its investment objective while applying an environmental, social and governance (“ESG”) methodology developed by the Fund’s subadviser in the selection of portfolio investments. The Fund invests, under normal circumstances, at least 80% of its investable assets in a diversified portfolio of high yield fixed income instruments that, at the time of investment, are included in the investable universe based on the subadviser’s ESG methodology described below. For purposes of this policy, high yield fixed income instruments include fixed income instruments rated Ba or lower by Moody's Investors Service, Inc. (“Moody's”) or BB or lower by S&P Global Ratings (“S&P”), and instruments either comparably rated by another nationally recognized statistical rating organization (“NRSRO”), or considered by the subadviser to be of comparable quality, that is, junk bonds, and other investments (including derivatives) with similar economic characteristics. In selecting the Fund’s portfolio investments, the subadviser incorporates proprietary ESG criteria and employs third-party screening services as described in more detail below. The term “investable assets” refers to the Fund’s net assets plus any borrowings for investment purposes. The Fund’s investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions.The subadviser’s ESG methodology begins with exclusionary screening, and then applies a proprietary scoring methodology focusing on factors that impact the environment and society, which include governance factors (“ESG Impact Ratings”), to construct the Fund’s portfolio.First, the subadviser will use third-party screening agents to exclude from all potential portfolio investments issuers that do not meet the subadviser’s investment criteria (which may be updated periodically). Such excluded issuers currently include: (i) those with exposure to controversial weapons (e.g., anti-personnel mines, biological and chemical weapons, cluster weapons, incendiary weapons, depleted uranium, nuclear weapons, and white phosphorus) and those with revenue above a certain threshold (as determined by the subadviser, which generally range from 5% to 20%, with the exception of gambling, which normally has a threshold of 50%) from conventional weapons (e.g., civilian firearms (such as guns, rifles, and pistols or components of these), military equipment, and service providers to civilian firearms and/or military equipment), tobacco, thermal coal generation and extraction, oil sands extraction and processing, artic oil and gas extraction and gambling activities; (ii) issuers that have carbon emissions activities above a certain emission intensity as determined by the subadviser; and (iii) issuers that are non-compliant with UN Global Compact principles. When selecting securities for the Fund, the subadviser seeks to ensure that the weighted average carbon intensity score of the portfolio as a whole is lower than the weighted average carbon intensity score of the Bloomberg US High Yield 1% Issuer Capped Index (the “Relevant Index”). The carbon intensity scores are calculated by the third party screening agent, who may not provide a carbon intensity score for each security in the Fund and Relevant Index. The average carbon intensity score of the Fund and the Relevant Index includes only securities that have carbon intensity scores.The principles of the UN Global Compact represent a set of values that the UN believes responsible businesses should incorporate into their operations in order to meet fundamental responsibilities in the areas of human rights, labor, environment and anti-corruption. To the extent an issuer’s status changes to meet the qualification for exclusion, the subadviser may take steps to divest its holdings of the issuer within a reasonable period of time after the issuer’s change in status. This screening criteria is subject to change over time at the subadviser’s discretion.Next, the subadviser assigns each potential investment an ESG Impact Rating (where possible). The subadviser assesses the type of investment and structure, and the ESG Impact Ratings are developed based on research and due diligence, including review of publicly available information as well as information from alternative data sources (e.g., non-governmental organization (“NGO”) analyses, governmental and inter-governmental studies, etc.) and third-party research and tools. The subadviser may supplement this information and adjust a rating based on direct engagement with the issuer. The ESG Impact Rating is assigned by assessing the impact of the following factors: environmental (e.g., reduction of environmental pollution, waste management, water consumption and climate change mitigation) and social (e.g., human rights, employee rights, health and safety and community relations). Governance factors (e.g., effective management and business conduct) are integrated into the assessment of factors that impact the environment and society. Issuers that score well with respect to these factors generally receive higher ESG Impact Ratings. While the subadviser considers ESG factors when evaluating an issuer, only one or two of these categories may be considered with respect to a particular investment or sector, and categories may be weighted differently according to the type of investment being considered.The subadviser seeks to assign each investment opportunity an ESG Impact Rating on a 100-point scale in 5-point increments, with 0 as the lowest and 100 as the highest ESG Impact Rating. An overall aggregated, or composite, ESG Impact Rating is also calculated, with ESG factors weighted differently depending on the industry. The ESG Impact Ratings are determined prior to purchase and reviewed at least annually. Under normal circumstances, the Fund will not purchase securities of issuers that have ESG Impact Ratings that are below a threshold established by the subadviser, except that the Fund may purchase a “Green Bond” from certain issuers whose securities may otherwise be excluded based on ESG Impact Ratings. A Green Bond is a type of fixed income instrument specifically earmarked to raise money for climate and environmental projects. The subadviser will seek to divest within a reasonable period of time from investments for which the ESG Impact Rating falls below the thresholds established by the subadviser. The subadviser may determine that there is not sufficient information available to assign an ESG Impact Rating with respect to certain securities and/or issuers. Up to 5% of the Fund’s total assets may normally comprise investments without ESG Impact Ratings. The subadviser may periodically update its ESG Impact Rating methodology.After identifying the relevant investable universe based on its ESG methodology (i.e., screening and application of ESG Impact Ratings), the subadviser then selects securities for the Fund using a combination of top-down economic analysis and bottom-up research in conjunction with proprietary quantitative models and risk management systems. In the top-down economic analysis, the subadviser develops views on economic, policy and market trends by continually evaluating economic data that affect the movement of markets and securities prices. In its bottom-up research, the subadviser develops an internal rating and outlook on issuers. The rating and outlook are determined based on a thorough review of the financial health and trends of the issuer, which includes a review of the composition of revenue, profitability, cash flow margin, and leverage, as well as an assessment of the issuer's corporate governance (e.g., ownership structures and board effectiveness). The subadviser may also consider investment factors such as expected total return, yield, spread and potential for price appreciation as well as credit quality, maturity and risk. The Fund may invest in a security based upon the expected total return rather than the yield of such security. When selecting securities for the Fund, the subadviser seeks to ensure that the weighted average ESG Impact Rating of the portfolio as a whole is higher than the weighted average ESG Impact Rating of the Relevant Index. The subadviser may not provide ESG Impact Ratings for certain securities in the Relevant Index, which under normal market conditions may be up to 15% of the Relevant Index. The average ESG Impact Rating of the Relevant Index includes only securities that have been rated.The Fund may invest up to 20% of its investable assets in U.S. currency-denominated fixed income securities of foreign governments and other foreign issuers, including Brady Bonds, which are long-term bonds issued by developing nations, and preferred stock. The Fund may also invest up to 10% of its investable assets in foreign currency-denominated fixed income securities issued by foreign or domestic issuers. Foreign government fixed income securities include securities issued by quasi-governmental entities, governmental agencies, supranational entities and other governmental entities. The Fund's investments in foreign issuers may include issuers located anywhere in the world, including emerging markets. From time to time the Fund’s investments may be concentrated in a geographic region or country.The Fund may use various derivative strategies to try to improve the Fund’s returns. The subadviser may also use hedging techniques to try to protect the Fund’s assets. Although the Fund has the flexibility to make use of derivatives, it may choose not to for a variety of reasons, even under very volatile market conditions.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; and is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
PGIM ESG High Yield Fund | Covenant Lite Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	“Covenant-Lite” Risk. Some of the loans or debt obligations in which the Fund may invest or get exposure to may be “covenant-lite”, which means the loans or obligations contain fewer financial maintenance covenants than other loans or obligations (in some cases, none) and do not include terms which allow the lender to monitor the borrower’s performance and declare a default if certain criteria are breached. An investment by the Fund in a covenant-lite loan may potentially hinder the ability to reprice credit risk associated with the issuer and reduce the ability to restructure a problematic loan and mitigate potential loss. The Fund may also experience difficulty, expenses or delays in enforcing its rights on its holdings of covenant-lite loans or obligations. As a result of these risks, the Fund’s exposure to losses may be increased, which could result in an adverse impact on the Fund’s net income and NAV.
PGIM ESG High Yield Fund | Credit Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Credit Risk. This is the risk that the issuer, the guarantor, or the insurer of a fixed income security, or the counterparty to a contract may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Additionally, fixed income securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer, or counterparty to pay back debt. The lower the credit quality of a bond, the more sensitive it is to credit risk.
PGIM ESG High Yield Fund | Debt Obligations Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Debt Obligations Risk. Debt obligations are subject to credit risk, market risk and interest rate risk. The Fund's holdings, share price, yield and total return may also fluctuate in response to bond market movements. The value of bonds may decline for issuer-related reasons, including management performance, financial leverage and reduced demand for the issuer’s goods and services. Certain types of fixed income obligations also may be subject to “call and redemption risk,”which is the risk that the issuer may call a bond held by the Fund for redemption before it matures and the Fund may not be able to reinvest at the same rate of interest and therefore would earn less income.
PGIM ESG High Yield Fund | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Derivatives Risk. Derivatives involve special risks and costs and may result in losses to the Fund. The successful use of derivatives requires sophisticated management, and, to the extent that derivatives are used, the Fund will depend on the subadviser’s ability to analyze and manage derivatives transactions. The prices of derivatives may move in unexpected ways, especially in abnormal market conditions. Some derivatives are “leveraged” or may create economic leverage for the Fund and therefore may magnify or otherwise increase investment losses to the Fund. The Fund's use of derivatives may also increase the amount of taxes payable by shareholders.Other risks arise from the potential inability to terminate or sell derivatives positions. A liquid secondary market may not always exist for the Fund's derivatives positions. In fact, many over-the-counter derivative instruments will not have liquidity beyond the counterparty to the instrument. Over-the-counter derivative instruments also involve the risk that the other party will not meet its obligations to the Fund. The use of derivatives also exposes the Fund to operational issues, such as documentation and settlement issues, systems failures, inadequate control and human error.Derivatives may also involve legal risks, such as insufficient documentation, the lack of capacity or authority of a counterparty to execute or settle a transaction, and the legality and enforceability of derivatives contracts. The U.S. Government and foreign governments have adopted (and may adopt further) regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements and risk exposure limitations. Regulation of derivatives may make derivatives more costly, limit their availability or utility to the Fund, or otherwise adversely affect their performance or disrupt markets.
PGIM ESG High Yield Fund | Economic And Market Events Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Economic and Market Events Risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth or the functioning of the securities markets, or otherwise reduce inflation, may at times result in unusually high market volatility, which could negatively impact performance. Governmental efforts to curb inflation often have negative effects on the level of economic activity. Relatively reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.
PGIM ESG High Yield Fund | Emerging Markets Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Emerging Markets Risk. The risks of foreign investments are greater for investments in or exposed to emerging markets. Emerging market countries typically have economic and political systems that are less fully developed, and can be expected to be less stable, than those of more developed countries. For example, the economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation. Low trading volumes may result in a lack of liquidity and price volatility. Emerging market countries may have policies that restrict investment by non-U.S. investors, or that prevent non-U.S. investors from withdrawing their money at will.The Fund may invest in some emerging markets that subject it to risks such as those associated with illiquidity, custody of assets, different settlement and clearance procedures and asserting legal title under a developing legal and regulatory regime to a greater degree than in developed markets or even in other emerging markets.
PGIM ESG High Yield Fund | ESG Methodology Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	ESG Methodology Risk. Because the subadviser utilizes screens and other exclusionary tools in its ESG methodology, this may result in the Fund forgoing opportunities to make certain investments when it might otherwise be advantageous to do so, or sell investments based on its ESG methodology criteria when it might be otherwise disadvantageous for it to do so. In evaluating an issuer, the subadviser is dependent upon information and data, including from third party data providers, that may be incomplete, inaccurate, or unavailable, or that may present conflicting information and data with respect to an issuer, which in each case could cause the subadviser to incorrectly assess an issuer’s business practices with respect to ESG. Issuers that are assigned a higher ESG Impact Rating by the subadviser may underperform similar issuers that have a lower ESG Impact Rating and/or may underperform the market as a whole. As a result, the Fund may underperform funds that do not screen or score companies based on ESG factors or funds that use a different ESG methodology. ESG Impact Ratings are inherently subjective and the subadviser’s assessment of an issuer, based on the issuer’s level of involvement in a particular industry or the issuer’s ESG Impact Ratings may differ from that of other funds or an investor. As a result, the Fund may invest in issuers that do not reflect the beliefs or values of any particular investor and may not be deemed to exhibit positive or favorable ESG characteristics if different metrics were used to evaluate them.
PGIM ESG High Yield Fund | Foreign Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign Securities Risk. Investments in securities of non-U.S. issuers (including those denominated in U.S. dollars) may involve more risk than investing in securities of U.S. issuers. Foreign political, economic and legal systems, especially those in developing and emerging market countries, may be less stable and more volatile than in the United States. Foreign legal systems generally have fewer regulatory requirements than the U.S. legal system, particularly those of emerging markets. In general, less information is publicly available with respect to non-U.S. companies than U.S. companies. Non-U.S. companies generally are not subject to the same accounting, auditing, and financial reporting standards as are U.S. companies. Additionally, the changing value of foreign currencies and changes in exchange rates could also affect the value of the assets the Fund holds and the Fund's performance. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. Investments in emerging markets are subject to greater volatility and price declines.In addition, the Fund's investments in non-U.S. securities may be subject to the risks of nationalization or expropriation of assets, imposition of currency exchange controls or restrictions on the repatriation of non-U.S. currency, confiscatory taxation and adverse diplomatic developments. Special U.S. tax considerations may apply.
PGIM ESG High Yield Fund | Increase In Expenses Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Increase in Expenses Risk. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Active and frequent trading of Fund securities can increase expenses.
PGIM ESG High Yield Fund | Interest Rate Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Interest Rate Risk. The value of your investment may go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration debt securities. Similarly, a rise in interest rates may also have a greater negative impact on the value of equity securities whose issuers expect earnings further out in the future. For example, a fixed income security with a duration of three years is expected to decrease in value by approximately 3% if interest rates increase by 1%. This is referred to as “duration risk.” When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as “prepayment risk.” When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Fund's holdings may fall sharply. This is referred to as “extension risk.”The Fund may lose money if short-term or long-term interest rates rise sharply or in a manner not anticipated by the subadviser.
PGIM ESG High Yield Fund | Junk Bonds Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Junk Bonds Risk. High-yield, high-risk bonds have predominantly speculative characteristics, including particularly high credit risk. Junk bonds tend to have lower market liquidity than higher-rated securities. The liquidity of particular issuers or industries within a particular investment category may shrink or disappear suddenly and without warning. The non-investment grade bond market can experience sudden and sharp price swings and become illiquid due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high profile default or a change in the market's psychology.
PGIM ESG High Yield Fund | Large Shareholder And Large Scale Redemption Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Large Shareholder and Large Scale Redemption Risk. Certain individuals, accounts, funds (including funds affiliated with the Manager) or institutions, including the Manager and its affiliates, may from time to time own or control a substantial amount of the Fund’s shares. There is no requirement that these entities maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy. The Fund’s ability to pursue its investment objective after one or more large scale redemptions may be impaired and, as a result, the Fund may invest a larger portion of its assets in cash or cash equivalents.
PGIM ESG High Yield Fund | Liquidity Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity Risk. Liquidity risk is the risk that the Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investors' interests in the Fund. The Fund may invest in instruments that trade in lower volumes and are more illiquid than other investments. If the Fund is forced to sell these investments to pay redemption proceeds or for other reasons, the Fund may lose money. In addition, when there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the instrument at all. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities.
PGIM ESG High Yield Fund | Management Risk [Member]

Risk [Text Block]	rr_RiskTextBlock	Management Risk. Actively managed funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but the subadviser's judgments about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements may be incorrect. Additionally, the investments selected for the Fund may underperform the markets in general, the Fund's benchmark and other funds with similar investment objectives.
PGIM ESG High Yield Fund | Market Disruption And Geopolitical Risks [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Disruption and Geopolitical Risks. Market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including Russia’s military invasion of Ukraine), geopolitical developments (including trading and tariff arrangements, sanctions and cybersecurity attacks), instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally).The extent and duration of such events and resulting market disruptions cannot be predicted, but could be substantial and could magnify the impact of other risks to the Fund. These and other similar events could adversely affect the U.S. and foreign financial markets and lead to increased market volatility, reduced liquidity in the securities markets, significant negative impacts on issuers and the markets for certain securities and commodities and/or government intervention. They may also cause short- or long-term economic uncertainties in the United States and worldwide. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively impacted. Further, due to closures of certain markets and restrictions on trading certain securities, the value of certain securities held by the Fund could be significantly impacted, which could lead to such securities being valued at zero.COVID-19 and the related governmental and public responses have had, and future public health epidemics may have an impact on the Fund’s investments and net asset value, and have led and may lead to increased market volatility and the potential for illiquidity in certain classes of securities and sectors of the market. Future public health epidemics mayresult in periods of business disruption, business closures, inability to obtain raw materials, supplies and component parts, and reduced or disrupted operations for the issuers in which the Fund invests. The occurrence, reoccurrence and pendency of public health epidemics could adversely affect the economies and financial markets either in specific countries or worldwide.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.
PGIM ESG High Yield Fund | New Fund Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	New Fund Risk. The Fund recently commenced operations. As a new and relatively small fund, the Fund's performance may not represent how the Fund is expected to or may perform in the long term if it becomes larger and after it has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in new and smaller funds. New and smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and achieve a representative portfolio composition. Accordingly, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, and may not employ a successful investment strategy, either of which could result in the Fund being liquidated at any time without shareholder approval and/or at a time that may not be favorable for all shareholders. Such a liquidation could result in transaction costs and have negative tax consequences for shareholders.
PGIM ESG High Yield Fund | Reference Rate Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Reference Rate Risk. The Fund may be exposed to financial instruments that recently transitioned from using or continue to use the London Interbank Offered Rate (“LIBOR”) or synthetic version thereof to determine payment obligations, financing terms, hedging strategies or investment value.The United Kingdom's Financial Conduct Authority (the “FCA”) announced a phase out of LIBOR such that after June 30, 2023, the overnight, 1-month, 3-month, 6-month and 12-month U.S. dollar LIBOR settings ceased to be published or are no longer representative. All other LIBOR settings and certain other interbank offered rates, such as the Euro Overnight Index Average (“EONIA”), ceased to be published after December 31, 2021. On December 16, 2022, the Federal Reserve Board adopted regulations implementing the Adjustable Interest Rate Act by identifying benchmarkrates based on the Secured Overnight Financing Rate that replaced LIBOR in different categories of financial contracts after June 30, 2023. These regulations apply only to contracts governed by U.S. law, among other limitations. The FCA will permit the use of synthetic U.S. dollar LIBOR rates for non-U.S. contracts through September 30, 2024, but any such rates would be considered non-representative of the underlying market.Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Parties to contracts, securities or other instruments using LIBOR may disagree on transition rates or the application of applicable transition regulation, potentially resulting in uncertainty of performance and the possibility of litigation. The Fund may have instruments linked to other interbank offered rates that may also cease to be published in the future.

[1] Investors who purchase $500,000 or more of Class A shares and sell these shares within 12 months of purchase are subject to a contingent deferred sales charge (“CDSC”) of 1.00%, although they are not subject to an initial sales charge. The CDSC is waived for certain retirement and/or benefit plans.

[2] Other expenses have been updated from the most recent annual report to reflect current expenses.

[3] PGIM Investments LLC (“PGIM Investments”) has contractually agreed, through December 31, 2024, to limit Total Annual Fund Operating Expenses after fee waivers and/or expense reimbursements to 0.80% of average daily net assets for Class A shares, 1.50% of average daily net assets for Class C shares, 0.54% of average daily net assets for Class Z shares and 0.41% of average daily net assets for Class R6 shares. This contractual waiver excludes interest, brokerage, taxes (such as income and foreign withholding taxes, stamp duty and deferred tax expenses), acquired fund fees and expenses, extraordinary expenses, and certain other Fund expenses such as dividend and interest expense and broker charges on short sales. Where applicable, PGIM Investments agrees to waive management fees or shared operating expenses on any share class to the same extent that it waives such expenses on any other share class. In addition, Total Annual Fund Operating Expenses for Class R6 shares will not exceed Total Annual Fund Operating Expenses for Class Z shares. Fees and/or expenses waived and/or reimbursed by PGIM Investments for the purpose of preventing the expenses from exceeding a certain expense ratio limit may be recouped by PGIM Investments within the same fiscal year during which such waiver and/or reimbursement is made if such recoupment can be realized without exceeding the expense limit in effect at the time of the recoupment for that fiscal year. This waiver may not be terminated prior to December 31, 2024 without the prior approval of the Fund’s Board of Directors.

[4] Class C shares are sold with a CDSC of 1.00% on sales made within 12 months of purchase.

[5] Direct Transfer Agent Accounts holding under $10,000 of Class Z shares are subject to the $15 fee.

[6] Since Inception returns for the Index are measured from the month-end closest to the Fund’s inception date.
