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 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 Expense Example, affect the Fund's performance.During the most recent fiscal year, the Fund's portfolio turnover rate was 37% of the average value of its portfolio.

Expenses Deferred Charges [Text Block]

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities of issuers in emerging markets. For purposes of this 80% policy, emerging markets means most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, Singapore, the United Kingdom, the United States, and most of the countries of Western Europe. For purposes of this 80% policy, equity securities include, without limitation, common stock, preferred stock, convertible securities, depositary receipts, participatory notes and other structured notes, real estate-related securities (including real estate investment trusts (“REITs”)), trust or partnership interests, rights and warrants to buy common stock, privately placed securities, and initial public offerings (“IPOs”). An emerging market issuer is one (i) that is organized under the laws of, or has a principal place of business in, an emerging market; (ii) for which the principal securities market is in an emerging market; (iii) that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or (iv) at least 50% of the assets of which are located in an emerging market. The Fund may invest in companies of any market capitalization. The Fund may invest in bonds rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”). The Fund may invest in derivatives, including but not limited to, futures, options, swaps, and forward foreign currency exchange contracts as a substitute for securities in which the Fund can invest; to hedge various investments; to seek to reduce currency deviations, where practicable, for the purpose of risk management; to seek to increase the Fund’s gains; and for the efficient management of cash flows. The Fund may invest in securities denominated in U.S. dollars, other major reserve currencies, such as the euro, yen and pound sterling, and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may, from time to time, hedge a portion of its foreign currency exposure into the U.S. dollar. The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder. The Investment Adviser allocates the Fund’s assets to different sub-advisers. When selecting sub-advisers, the Investment Adviser takes into account a wide variety of factors and considerations, including among other things the investment strategy of a potential sub-adviser, its personnel, and its fit with other sub-advisers to the Fund. Among those, the Investment Adviser will typically consider the extent to which a potential sub-adviser takes into account environmental, social, and governance (“ESG”) factors as part of its investment process. ESG factors will be only one of many considerations in the Investment Adviser’s evaluation of any potential sub-adviser; the extent to which ESG factors will affect the Investment Adviser’s decision to retain a sub-adviser, if at all, will depend on the analysis and judgment of the Investment Adviser. Delaware Investments Fund Advisers and Macquarie Investment Management Global Limited (together, “DIFA”), Sustainable Growth Advisers, LP (“SGA”), and Voya Investment Management Co. LLC (“Voya IM”) (each, a “Sub-Adviser” and collectively, the “Sub-Advisers”) provide the day-to-day management of the Fund. The Sub-Advisers act independently of each other and use their own methodology for selecting investments. The Investment Adviser will determine the amount of Fund assets allocated to each Sub-Adviser. Each Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others. In addition, Voya IM may sell securities to rebalance and reconstitute its investments in connection with such changes in the Index (as defined below). The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets. DIFA DIFA believes that, although market price and intrinsic business value are positively correlated in the long run, short-term divergences can emerge. DIFA seeks to take advantage of these divergences through a disciplined, fundamental, bottom-up approach. DIFA seeks to invest in companies with sustainable franchises when they are trading at a significant discount to DIFA’s conservative intrinsic value estimate. DIFA also prefers companies that have large market opportunities in which to deploy capital, ensuring that they grow faster than the overall economy. Fundamental bottom-up research is the core of the investment process. DIFA’s fundamental research process can be broken down into two main components: analyzing a company’s sustainability and assessing its intrinsic value. Sustainability analysis involves identification of a company’s source of competitive advantage and the ability of its management to maximize its return potential. Intrinsic value assessment is typically quantitatively driven by a number of valuation methods including discounted cash flow, replacement cost, private market transaction, and multiples analysis. This bottom-up approach considers current and historical macro drivers that impact a firm’s ability to generate returns over the long-term. SGA SGA is focused on identifying and owning the rare businesses which generate predictable, sustainable earnings and cash flow growth over time with lower variability. SGA’s objective is to translate earnings growth into portfolio returns. The companies in which SGA invests have unique characteristics that lead to a high degree of predictability, strong profitability, and well above average earnings and cash flow growth. These characteristics include pricing power, recurring revenues, and secular growth opportunity, as well as financial and management strength. SGA’s emerging markets growth strategy focuses solely on the companies they believe will also benefit in a sustained way from rising incomes and increasing consumption within developing economies. Voya IM To manage its portion of the Fund’s assets, Voya IM employs a “passive management” approach designed to track the performance of a custom index created by FTSE Russell for Voya IM, the FTSE Emerging Plus Korea Select Factor Index (the “Index”). The Index is designed to capture exposure to a broad set of five factors that contribute to emerging equity market performance. These five factors are Low Volatility, Momentum, Quality, Size, and Value. As a result of the five factor selection process, the Index may be focused in one or more sectors, which may change from time to time. As of December 31, 2024, a portion of the Index was focused in the energy, materials and technology sectors. Voya IM seeks to replicate the performance of the Index, meaning it generally will invest in all of the securities in the Index in weightings, consistent with that of the Index. The Fund’s portfolio may not always hold all of the same securities as the Index. Voya IM may also invest in ETFs, stock index futures, and other derivatives as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Fund’s cash position. Although Voya IM attempts to track, as closely as possible, the performance of the Index, the Fund’s portfolio does not always perform exactly like the Index. Unlike the Index, the Fund has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.

Company: The price of a company’s stock could decline or underperform for many reasons, including, among others, poor management, financial problems, reduced demand for the company’s goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.

Credit: The Fund could lose money if the issuer or guarantor of a debt instrument in which the Fund invests, or the counterparty to a derivative contract the Fund entered into, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services, or otherwise) as unable or unwilling, to meet its financial obligations.

Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying asset, reference rate, or index credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the asset, reference rate, or index being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment.

Environmental, Social, and Governance (Multi-Manager): The Investment Adviser’s consideration of ESG factors in selecting sub-advisers for the Fund is based on information that is not standardized, some of which can be qualitative and subjective by nature. There is no minimum percentage of the Fund’s assets that will be allocated to sub-advisers that consider ESG factors as part of their investment processes, and the Investment Adviser may choose to select sub-advisers that do not consider ESG factors as part of their investment processes. It is possible that the Fund will have less exposure to ESG-focused strategies than other comparable mutual funds. There can be no assurance that a sub-adviser selected by the Investment Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential sub-adviser, and such a sub-adviser may, in fact, underperform other potential sub-advisers.

•Energy Sector: Investments in companies in the energy sector are subject to risks related to fluctuations in energy prices, which can be the result of, among other things, geopolitical developments, changes in economic conditions, changes in currency exchange rates, interest rates, developments in energy exploration and production, terrorist acts, and natural disasters. The values of companies in the energy sector can be highly volatile and may be affected by changes in transportation storage, and labor costs, and the development of alternative energy sources and energy conservation activities. These companies are at risk of environmental damage claims and other potential civil liabilities.

•Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.

High-Yield Securities: Lower-quality securities including securities that are or have fallen below investment grade have greater credit risk and liquidity risk than higher-quality (investment grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower-quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity risk and price volatility.

Initial Public Offerings: Investments in IPOs and companies that have recently gone public have the potential to produce substantial gains for the Fund. However, there is no assurance that the Fund will have access to profitable IPOs or that the IPOs in which the Fund invests will rise in value. Furthermore, the value of securities of newly public companies may decline in value shortly after the IPO. When the Fund’s asset base is small, the impact of such investments on the Fund’s return will be magnified. If the Fund’s assets grow, it is likely that the effect of the Fund’s investment in IPOs on the Fund’s return will decline.

Investment Model: A Sub-Adviser’s proprietary investment model may not adequately take into account existing or unforeseen market factors or the interaction among such factors, including changes in how such factors interact, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for the Fund. Funds that are actively managed, in whole or in part, according to a quantitative investment model (including models that utilize forms of artificial intelligence, such as machine learning) can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance.

Market: 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 instruments. Additionally, legislative, regulatory or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs, and impair the ability of the Fund to achieve its investment objectives.

Market Disruption and Geopolitical: The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, tariffs and other restrictions on trade or economic sanctions, rapid technological developments (such as artificial intelligence technologies), and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and global economies and markets, generally. For example, the COVID-19 pandemic resulted in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of the Fund’s investments, including beyond the Fund’s direct exposure to Russian issuers or nearby geographic regions. Furthermore, the prolonged conflict between Hamas and Israel, and the potential expansion of the conflict in the surrounding areas and the involvement of other nations in such conflict, such as the Houthi movement's attacks on marine vessels in the Red Sea, could further destabilize the Middle East region and introduce new uncertainties in global markets, including the oil and natural gas markets. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund’s investments. Any of these occurrences could disrupt the operations of the Fund and of the Fund’s service providers.

Preferred Stocks: Preferred stock generally has preference over common stock but is generally subordinate to debt instruments with respect to dividends and liquidation. Preferred stocks are subject to the risks associated with other types of equity securities, as well as greater credit or other risks than senior debt instruments. In addition, preferred stocks are subject to other risks, such as risks related to deferred and omitted distributions, limited voting rights, liquidity, interest rate, regulatory changes and special redemption rights.

Real Estate Companies and Real Estate Investment Trusts: Investing in real estate companies and REITs may subject the Fund to risks similar to those associated with the direct ownership of real estate, including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, market interest rates, zoning laws, regulatory limitations on rents, property taxes, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill of the REIT’s sponsor. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.

Value Investing: Securities that appear to be undervalued may never appreciate to the extent expected. Further, because the prices of value-oriented securities tend to correlate more closely with economic cycles than growth-oriented securities, they generally are more sensitive to changing economic conditions, such as changes in market interest rates, corporate earnings and industrial production. The manager may be wrong in its assessment of a company’s value and the securities the Fund holds may not reach their full values. Risks associated with value investing include that a security that is perceived by the manager to be undervalued may actually be appropriately priced and, thus, may not appreciate and provide anticipated capital growth. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Fund’s relative performance may suffer. There is a risk that funds that invest in value-oriented securities may underperform other funds that invest more broadly.
