Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may mean higher taxes if you are investing in a taxable account. These costs are not reflected in annual fund operating expenses or in the expense example, and can affect the fund's performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 36% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	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 (including one year of capped expenses in each period) remain the same. Class C shares generally convert automatically to Class A shares after 8 years. The information presented in the Example for Class C reflects the conversion of Class C shares to Class A shares after 8 years. See ”Class C Shares“ in the ”Choosing a Share Class“ section of the prospectus for more information. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Main Investments. Under normal circumstances, the fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in high yield bonds (also known as “junk bonds”) and other debt securities issued by governments and corporations in emerging market countries (i.e., the issuer is traded mainly in an emerging market, is organized under the laws of an emerging market country or is a company with more than half of its business in emerging markets) or the return on which is derived primarily from emerging markets.The fund considers “emerging markets” to include, but not to be limited to: (i) the countries or markets that are part of the JP Morgan Emerging Markets Bond (EMBI) Global Diversified Index; or (ii) the countries or markets that are classified as “emerging market and developing economies” by the International Monetary Fund (“IMF”) (World Economic Outlook); or (iii) countries listed as low or middle (both lower middle and higher middle) income by the World Bank, if a country is an emerging market and if such country is not listed in the JP Morgan EMBI Global Diversified Index and if it is not classified as an “emerging market and developing economy” by the IMF.The fund may invest without limit in investment-grade debt securities and in junk bonds, which are those below the fourth credit grade (grade BB/Ba and below) and may include debt securities not currently paying interest and debt securities in default.The fund invests at least 50% of total assets in US dollar-denominated securities.Management process. Portfolio management typically considers a number of factors, including economic and currency outlooks, possible interest rate movements, capital flows, debt levels, inflation trends, credit quality of issuers, security characteristics and changes in supply and demand within global bond markets. Portfolio management may consider financially material Environmental, Social and Governance (ESG) factors in its fundamental analysis. In evaluating ESG issues, portfolio management refers to internal securities specific ESG ratings, internal and external ESG research and other factors.Portfolio management may also adjust the duration (a measure of sensitivity to interest rate movements) of the fund’s portfolio, depending on its outlook for interest rates.Derivatives. Portfolio management generally may use futures contracts or options, which are types of derivatives (contracts whose value are based on, for example, indices, currencies or securities) as a hedge against anticipated changes in interest rates, fixed income markets or currency markets, for duration management (i.e., reducing or increasing the sensitivity of the fund's portfolio to interest rate changes), or for non-hedging purposes to seek to enhance potential gains. In addition, portfolio management generally may use forward currency contracts (i) to hedge the fund's exposure to changes in foreign currency exchange rates on its foreign currency denominated portfolio holdings; (ii) to facilitate transactions in foreign currency denominated securities; or (iii) for non-hedging purposes to seek to enhance potential gains.The fund may also use other types of derivatives (i) for hedging purposes; (ii) for risk management; (iii) for non-hedging purposes to seek to enhance potential gains; or (iv) as a substitute for direct investment in a particular asset class or to keep cash on hand to meet shareholder redemptions.Securities lending. The fund may lend securities (up to one-third of total assets) to approved institutions, such as registered broker-dealers, banks and pooled investment vehicles.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;text-transform:uppercase;">Main Risks</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	There are several risk factors that could hurt the fund’s performance, cause you to lose money or cause the fund’s performance to trail that of other investments. The fund may not achieve its investment objective, and is not intended to be a complete investment program. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.Credit risk. The fund's performance could be hurt if an issuer of a debt security suffers an adverse change in financial condition that results in the issuer not making timely payments of interest or principal, a security downgrade or an inability to meet a financial obligation. Credit risk is greater for lower-rated securities.Because the issuers of high yield debt securities, or junk bonds (debt securities rated below the fourth highest credit rating category), may be in uncertain financial health, the prices of their debt securities can be more vulnerable to bad economic news, or even the expectation of bad news, than investment-grade debt securities. Credit risk for high yield securities is greater than for higher-rated securities.Because securities in default generally have missed one or more payments of interest and/or principal, an investment in such securities has an increased risk of loss. Issuers of securities in default have an increased likelihood of entering bankruptcy or beginning liquidation procedures which could impact the fund's ability to recoup its investment. Securities in default may be illiquid or trade in low volumes and thus may be difficult to value.Market disruption risk. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, public health crises and related geopolitical events have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Market disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by a market disruption, the duration and effects may not be the same for all types of assets.Russia's recent military incursions in Ukraine have led to, and may lead to additional sanctions being levied by the United States, European Union and other countries against Russia. Russia's military incursion and the resulting sanctions could adversely affect global energy and financial markets and thus could affect the value of the fund's investments, even beyond any direct exposure the fund may have to Russian issuers or the adjoining geographic regions. The extent and duration of the military action, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions caused by Russian military action or resulting sanctions may magnify the impact of other risks described in this “MAIN RISKS” section.Other recent market disruption events include the pandemic spread of the novel coronavirus known as COVID-19, and the significant uncertainty, market volatility, decreased economic and other activity, increased government activity, including economic stimulus measures, and supply chain disruptions that it has caused. The full effects, duration and costs of the COVID-19 pandemic are impossible to predict, and the circumstances surrounding the COVID-19 pandemic will continue to evolve, including the risk of future increased rates of infection due to low vaccination rates and/or the lack of effectiveness of current vaccines against new variants. The pandemic has affected and may continue to affect certain countries, industries, economic sectors, companies and investment products more than others, may exacerbate existing economic, political, or social tensions and may increase the probability of an economic recession or depression. The fund and its investments may be adversely affected by the effects of the COVID-19 pandemic, and the pandemic may result in the fund and its service providers experiencing operational difficulties in coordinating a remote workforce and implementing their business continuity plans, among others. The disruptions caused by the COVID-19 pandemic may magnify the impact of each of the other risks described in this “MAIN RISKS” section and may increase volatility in one or more markets in which the fund invests leading to the potential for greater losses for the fund.Interest rate risk. When interest rates rise, prices of debt securities generally decline. The longer the duration of the fund’s debt securities, the more sensitive the fund will be to interest rate changes. (As a general rule, a 1% rise in interest rates means a 1% fall in value for every year of duration.) Recent and potential future changes in monetary policy made by central banks or governments are likely to affect the level of interest rates. Rising interest rates may prompt redemptions from the fund, which may force the fund to sell investments at a time when it is not advantageous to do so, which could result in losses. The fund may be subject to a greater risk of rising interest rates following periods of low rates, including the current low rate period. In addition, in response to the COVID-19 pandemic, as with other serious economic disruptions, governmental authorities and regulators have enacted significant fiscal and monetary policy changes, including providing direct capital infusions into companies, creating new monetary programs and lowering interest rates considerably. If these actions are modified or reversed or are ineffective in achieving their desired outcomes, the fund could be adversely affected by periods of heightened volatility and uncertainty.London Interbank Offered Rate (LIBOR), the benchmark rate for certain floating rate securities, has been phased out as of the end of 2021 for most maturities and currencies, although certain widely used US Dollar LIBOR rates are expected to continue to be published through June 2023 to assist with the transition. The fund or the instruments in which the fund invests may be adversely affected by the phase out by, among other things, increased volatility or illiquidity. There remains uncertainty regarding the future use of LIBOR and the nature of any replacement reference rate and, accordingly, it is difficult to predict the impact to the fund of the transition away from LIBOR.Prepayment and extension risk. When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the fund’s assets tied up in lower interest debt obligations. Ultimately, any unexpected behavior in interest rates could increase the volatility of the fund’s share price and yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances.High yield debt securities risk. High yield debt securities, or junk bonds, are generally regarded as speculative with respect to the issuer’s continuing ability to meet principal and interest payments. High yield debt securities’ total return and yield may generally be expected to fluctuate more than the total return and yield of investment-grade debt securities. A real or perceived economic downturn or an increase in market interest rates could cause a decline in the value of high yield debt securities, result in increased redemptions and/or result in increased portfolio turnover, which could result in a decline in net asset value of the fund, reduce liquidity for certain investments and/or increase costs. High yield debt securities are often thinly traded and can be more difficult to sell and value accurately than investment-grade debt securities as there may be no established secondary market. Investments in high yield debt securities could increase liquidity risk for the fund. In addition, the market for high yield debt securities can experience sudden and sharp volatility which is generally associated more with investments in stocks.Foreign investment risk. The fund faces the risks inherent in foreign investing. Adverse political, economic or social developments, as well as US and foreign government actions such as the imposition of tariffs, economic and trade sanctions or embargoes, could undermine the value of the fund’s investments, prevent the fund from realizing the full value of its investments or prevent the fund from selling securities it holds. Financial reporting standards for companies based in foreign markets differ from those in the US. Additionally, foreign securities markets generally are smaller and less liquid than US markets. To the extent that the fund invests in non-US dollar denominated foreign securities, changes in currency exchange rates may affect the US dollar value of foreign securities or the income or gain received on these securities. In addition, because non-US markets may be open on days when the fund does not price its shares, the value of the securities in the fund’s portfolio may change on days when shareholders will not be able to purchase or sell the fund’s shares.Emerging markets risk. Foreign investment risks are greater in emerging markets than in developed markets. Investments in emerging markets are often considered speculative.Regional focus risk. Focusing investments in a single country or few countries, or regions, involves increased currency, political, regulatory and other risks. Market swings in such a targeted country, countries or regions are likely to have a greater effect on fund performance than they would in a more geographically diversified fund.Currency risk. Changes in currency exchange rates may affect the value of the fund’s investments and the fund’s share price. To the extent the fund seeks to hedge part or all of its foreign currency exposure, the fund may not be successful in hedging against currency changes. The fund’s US dollar share price may go down if the value of the local currency of the non−US markets in which the fund invests depreciates against the US dollar. This is true even if the local currency value of securities in the fund’s holdings goes up. Furthermore, the fund’s use of forward currency contracts may eliminate some or all of the benefit of an increase in the value of a foreign currency versus the US dollar. The value of the US dollar measured against other currencies is influenced by a variety of factors. These factors include: interest rates, national debt levels and trade deficits, changes in balances of payments and trade, domestic and foreign interest and inflation rates, global or regional political, economic or financial events, monetary policies of governments, actual or potential government intervention, global energy prices, political instability and government monetary policies and the buying or selling of currency by a country’s government. Currency exchange rates can be volatile and can change quickly and unpredictably, thereby impacting the value of the fund’s investments.Non-diversification risk. The fund is classified as non-diversified under the Investment Company Act of 1940, as amended. This means that the fund may invest in securities of relatively few issuers. Thus, the performance of one or a small number of portfolio holdings can affect overall performance.Derivatives risk. Risks associated with derivatives may include the risk that the derivative is not well correlated with the security, index or currency to which it relates; the risk that derivatives may result in losses or missed opportunities; the risk that the fund will be unable to sell the derivative because of an illiquid secondary market; the risk that a counterparty is unwilling or unable to meet its obligation; and the risk that the derivative transaction could expose the fund to the effects of leverage, which could increase the fund's exposure to the market and magnify potential losses.Security selection risk. The securities in the fund’s portfolio may decline in value. Portfolio management could be wrong in its analysis of industries, companies, economic trends, ESG factors, the relative attractiveness of different securities or other matters.Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different from the value realized upon such investment’s sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares.Liquidity risk. In certain situations, it may be difficult or impossible to sell an investment and/or the fund may sell certain investments at a price or time that is not advantageous in order to meet redemption requests or other cash needs. Unusual market conditions, such as an unusually high volume of redemptions or other similar conditions could increase liquidity risk for the fund, and in extreme conditions, the fund could have difficulty meeting redemption requests.Securities lending risk. Securities lending involves the risk that the fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities, or a decline in the value of any investments made with cash collateral or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the securities.Counterparty risk. A financial institution or other counterparty with whom the fund does business, or that underwrites, distributes or guarantees any investments or contracts that the fund owns or is otherwise exposed to, may decline in financial health and become unable to honor its commitments. This could cause losses for the fund or could delay the return or delivery of collateral or other assets to the fund.Operational and technology risk. Cyber-attacks, disruptions or failures that affect the fund’s service providers or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations. For example, the fund’s or its service providers’ assets or sensitive or confidential information may be misappropriated, data may be corrupted and operations may be disrupted (e.g., cyber-attacks, operational failures or broader disruptions may cause the release of private shareholder information or confidential fund information, interfere with the processing of shareholder transactions, impact the ability to calculate the fund’s net asset value and impede trading). Market events and disruptions also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund’s operations.While the fund and its service providers may establish business continuity and other plans and processes that seek to address the possibility of and fallout from cyber-attacks, disruptions or failures, there are inherent limitations in such plans and systems, including that they do not apply to third parties, such as fund counterparties, issuers of securities held by the fund or other market participants, as well as the possibility that certain risks have not been identified or that unknown threats may emerge in the future and there is no assurance that such plans and processes will be effective. Among other situations, disruptions (for example, pandemics or health crises) that cause prolonged periods of remote work or significant employee absences at the fund’s service providers could impact the ability to conduct the fund’s operations. In addition, the fund cannot directly control any cybersecurity plans and systems put in place by its service providers, fund counterparties, issuers of securities held by the fund or other market participants.
