The 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 whether or not you redeem all of your shares at the end of those periods (except as indicated with respect to Class C shares). The Example reflects Class C shares converting into Investor Class shares in years 9-10; expenses could be lower if you are eligible to convert to Class A shares instead. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects the contractual fee waiver and/or expense reimbursement arrangement, if applicable, for the current duration of the arrangement only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

oef_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its assets (net assets plus any borrowings for investment purposes) in fixed income securities of issuers in emerging markets. Fixed income securities are debt obligations and similar instruments that represent a creditor relationship with an issuer or trust and generally provide for the payment of interest (fixed, floating, or otherwise variable) and the repayment of principal, whether at maturity or over time. An issuer of a security is considered to be an emerging market issuer based on the issuer’s “country of risk” (or similar designation) as determined by a third-party such as Bloomberg. Candriam, the Fund’s Subadvisor, has discretion to determine the countries considered to be emerging market countries, including taking into consideration a variety of factors such as the development of a country’s financial and capital markets and inclusion in an index, such as the J.P. Morgan Emerging Market Bond Index, considered by the Subadvisor to be representative of emerging markets.

The securities in which the Fund invests may be denominated in foreign currency. The debt securities in which the Fund invests may consist of securities that are rated below investment grade. Below investment grade securities are generally securities that receive low ratings from a nationally recognized statistical rating organization (“NRSRO”) (such as securities rated lower than BBB- and Baa3), or if unrated, are deemed to be of comparable quality by the Subadvisor. Securities rated below investment grade by a NRSRO are commonly referred to as “high yield securities” or “junk bonds.” If NRSROs assign different ratings to the same security, the Fund will use the higher rating for purposes of determining the security's credit quality. The Fund may invest in fixed income securities of any duration or maturity.

The Fund's principal investments include sovereign, quasi-sovereign and corporate Eurobonds. The Fund may invest in floating rate notes and inverse floating rate notes. The Fund may also invest in derivative instruments, such as forward commitments, futures, options and swap agreements to try to enhance returns or reduce the risk of loss by hedging certain of its holdings. The Fund may invest up to 20% of its total assets in swaps, including credit default swaps and credit default swap indices. The Fund may buy and sell currency on a spot basis, buy foreign currency options, and enter into foreign currency forward contracts. These techniques may be used for any purpose, including to seek to increase the Fund's return.

Investment Process: The Subadvisor identifies investment opportunities by deploying a relative value focused investment approach. The approach consists of three primary layers of analysis. The first layer assesses medium-term sovereign creditworthiness and sets up the basis for identifying the second and third layer investment opportunities, which are relative country (second layer) and instrument (third layer) investment opportunities. The Subadvisor also considers key fundamental macro-economic drivers such as growth and inflation dynamics, internal and external imbalances as well as structural reform and political risk trends. The investment approach is aware of environmental, social and governance (“ESG”) risks as ESG factors are explicitly integrated in the sovereign creditworthiness analysis. The Subadvisor may avoid investments in sovereign or corporate issuers where the combination of fundamental and ESG risks are not appropriately reflected in valuations.

In addition, the Subadvisor implements a Controversial Activity Exclusion policy related to companies and industries involved with the production of coal, tobacco products, chemical, biological or white phosphorus weapons, and gambling.

The Subadvisor may sell a security if it believes the security will no longer contribute to meeting the investment objective of the Fund.

Performance Narrative [Text Block]

oef_PerformanceNarrativeTextBlock

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns compare with those of a broad measure of market performance over time. Sales loads, if any, are not reflected in the bar chart. If they were, returns would be less than those shown. The Fund has selected the JPMorgan EMBI Global Diversified Index to represent a broad measure of market performance.

Index returns reflect no deductions for fees, expenses or taxes, except for foreign withholding taxes where applicable.

Performance data for the classes varies based on differences in their fee and expense structures. Performance data is not shown for classes with less than one calendar year of performance. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Please visit nylim.com/funds for more recent performance information.

After-tax returns are calculated using the highest individual federal marginal income tax rates in effect at the time of each distribution or capital gain or upon the sale of Fund shares, and do not reflect the impact of state and local taxes. In some cases, the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of shares at the end of the measurement period. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns are not relevant if you hold your shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns shown are for Class I shares. After-tax returns for the other share classes may vary.

Market Risk: Changes in markets may cause the value of investments to fluctuate, which could cause the Fund to underperform other funds with similar investment objectives and strategies. Such changes may be rapid and unpredictable. From time to time, markets may experience periods of stress as a result of various market, economic, social and geopolitical factors (including responses to government actions or interventions), such as the imposition (or the threatened imposition) of tariffs for potentially prolonged periods that may result in: (i) increased market volatility; (ii) reduced market liquidity; and (iii) increased redemptions of shares. Certain securities may be difficult to value under such conditions, and such conditions may add significantly to the risk of volatility in the net asset value of the Fund's shares and adversely affect the Fund and its investments.

Foreign Securities Risk: An issuer of a security is considered to be a U.S. or foreign issuer based on the issuer’s “country of risk” (or similar designation) as determined by a third party such as Bloomberg (or another similar third party). The issuer’s “country of risk” is determined based on a number of criteria, which may change from time to time and currently include, but are not limited to, its country of domicile, the primary stock exchange on which it trades, the location from which the majority of its revenue comes, and its reporting currency.

Investments in foreign (non-U.S.) securities may be riskier than investments in U.S. securities. Foreign regulatory regimes and securities markets can have less stringent investor protections and disclosure standards and less liquid trading markets than U.S. regulatory regimes and securities markets, and can experience political, social and economic developments (such as government expropriation, excessive taxation, political or social instability, trade restrictions (including tariffs) or economic sanctions) that may affect the value of investments in foreign securities. There can also be difficulty obtaining and enforcing judgments against issuers in foreign countries. Foreign securities may also subject the Fund's investments to changes in currency rates. Changes in the value of foreign currencies may make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. Economic sanctions may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and other similar governmental actions or developments could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell certain foreign securities or groups of foreign securities, and thus may make the Fund’s investments in such securities less liquid or more difficult to value. Such sanctions may also cause a decline in the value of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country. In addition, as a result of economic sanctions and other similar governmental actions or developments, the Fund may be forced to sell or otherwise dispose of foreign investments at inopportune times or prices. The Fund may seek to hedge against its exposure to changes in the value of foreign currency, but there is no guarantee that such hedging techniques will be successful in reducing any related foreign currency valuation risk. These risks may be greater with respect to securities of companies that conduct their business activities in emerging markets or whose securities are traded principally in emerging markets.

Sovereign Debt Risk: The debt securities issued by sovereign entities may decline as a result of default or other adverse credit event resulting from a sovereign debtor's unwillingness or inability to repay principal and pay interest in a timely manner, which may be affected by a variety of factors, including its cash flow situation, the extent of its reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor's policy toward international lenders, and the political constraints to which a sovereign debtor may be subject. Sovereign debt risk is increased for emerging market issuers.

Floating Rate Notes and Variable Rate Notes Risk: Floating and variable rate notes provide for a periodic adjustment in the interest rate paid on the securities. The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate notes may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund's ability to sell the securities at any given time. Securities with floating interest rates generally are less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much or as fast as interest rates in general. Floating rate loans and other similar debt obligations that lack financial maintenance covenants or possess fewer or contingent financial maintenance covenants and other financial protections for lenders and investors (sometimes referred to as “covenant-lite” loans or obligations) are generally subject to more risk than investments that contain traditional financial maintenance covenants and financial reporting requirements. The terms of many floating rate notes and other instruments are tied to reference rates or benchmarks such as the Secured Overnight Financing Rate (“SOFR”).

Risk/Return:

Liquidity and Valuation Risk: The Fund’s investments may be illiquid at the time of purchase or liquid at the time of purchase and subsequently become illiquid due to, among other things, events relating to the issuer of the securities, market events, operational issues, economic conditions, investor perceptions or lack of market participants. The lack of an active trading market may make it difficult to sell or obtain an accurate price for a security. If market conditions or issuer specific developments make it difficult to value securities, the Fund may value these securities using more subjective methods, such as fair value pricing. In such cases, the value determined for a security could be different than the value realized upon

such security's sale. As a result, an investor could pay more than the market value when buying shares or receive less than the market value when selling shares. This could affect the proceeds of any redemption or the number of shares an investor receives upon purchase. The Fund is subject to the risk that it could not meet redemption requests within the allowable time period without significant dilution of remaining investors' interests in the Fund. To meet redemption requests or to raise cash to pursue other investment opportunities, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions, which may adversely affect the Fund’s performance. These risks are heightened for fixed-income instruments in a changing or volatile interest rate environment.

Money Market/Short-Term Securities Risk: To the extent the Fund holds cash or invests in money market or short-term securities, the Fund may be less likely to achieve its investment objective. In addition, it is possible that the Fund's investments in these instruments could lose money.
