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 mean higher taxes if you are investing 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 75% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	75.00%
Expenses Deferred Charges [Text Block]	rr_ExpensesDeferredChargesTextBlock	A contingent deferred sales charge of 1.00% is assessed on certain redemptions of Class A shares made within 18 months after purchase where no initial sales charge was paid at the time of purchase as part of an investment of $1 million or more.

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:11.16pt;font-weight:bold;text-transform:uppercase;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in a portfolio of equity securities. The Fund will provide 60 days’ prior notice of any change in this investment policy. The Fund invests primarily in the equity securities included in the MSCI World Value IndexSM (“Index”). The Fund invests in securities of issuers in a number of different countries, including the United States.The sub-adviser (“Sub-Adviser”) seeks to maximize total return to the extent consistent with maintaining lower volatility than the Index. Volatility generally measures how much a fund’s returns have varied over a specified time frame.The Fund may invest in derivative instruments including, but not limited to, index futures. The Fund typically uses derivatives as a substitute for purchasing securities included in the Index or for the purpose of maintaining equity market exposure on its cash balance.The Fund may invest in real estate-related securities including real estate investment trusts.The Fund may invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and applicable exemptive orders thereunder (“1940 Act”).The Sub-Adviser creates a target universe that consists of dividend paying securities by screening for companies that exhibit stable dividend yields within each industry sector. Once the Sub-Adviser creates this target universe, the Sub-Adviser seeks to identify the most attractive securities within various geographic regions and sectors by ranking each security relative to other securities within its region or sector, as applicable, using proprietary fundamental sector-specific models. The Sub-Adviser then uses optimization techniques to seek to achieve the portfolio’s target dividend yield, which is expected to be higher than the Index in aggregate, manage target beta, determine active weights, and neutralize region and sector exposures in order to create a portfolio that the Sub-Adviser believes will provide the potential for maximum total return consistent with maintaining lower volatility than the Index. Under certain market conditions, the Fund will likely earn a lower level of total return than it would in the absence of its strategy of maintaining a relatively lower level of volatility.In evaluating investments for the Fund, the Sub-Adviser normally expects to take into account environmental, social, and governance (“ESG”) factors to determine whether any or all of those factors might have a material effect on the value, risks, or prospects of a company. The Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research as material to a particular company or the industry in which it operates and on third-party evaluations of a company’s ESG standing. The Sub-Adviser may give environmental, social, and governance factors equal consideration or may focus on one or more of those factors as the Sub-Adviser considers appropriate. The Sub-Adviser may consider specific ESG metrics or a company’s progress or lack of progress toward meeting ESG targets. ESG factors will be only one consideration in the Sub-Adviser’s evaluation of any potential investment, and the effect, if any, of ESG factors on the Sub-Adviser’s decision whether to invest in any case will vary depending on the judgment of the Sub-Adviser.The Fund may lend portfolio securities on a short-term or long-term basis, up to 30% of its total assets.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:11.16pt;font-weight:bold;text-transform:uppercase;">Principal Risks</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds.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 company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.Currency: To the extent that the Fund invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Fund through foreign currency exchange transactions.Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity 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 currency, security or other risk 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. In addition, given their complexity, derivatives expose the Fund to the risk of improper valuation.Dividend: Companies that issue dividend yielding equity securities are not required to continue to pay dividends on such securities. Therefore, there is the possibility that such companies could reduce or eliminate the payment of dividends in the future. As a result, the Fund’s ability to execute its investment strategy may be limited.Environmental, Social and/or Governance (strategy): The Sub-Adviser ’s consideration of environmental, social and/or governance (“ESG”) factors in selecting investments for the Fund may cause it to forego other favorable investments that other investors who do not consider similar factors or who evaluate them differently might select. This may cause the Fund to underperform the stock market or relevant benchmark as a whole or other funds that do not consider ESG factors or that use such factors differently. The Sub-Adviser’s consideration of ESG factors is qualitative and subjective by nature, and it is possible that it will have an adverse effect on the Fund’s performance. In evaluating a company or issuer in light of ESG factors, the Sub-Adviser may consider information and data obtained through voluntary or third-party reporting that may be incomplete or inaccurate. It is possible the companies or issuers identified through the Sub-Adviser’s consideration of ESG factors will not operate as expected and will not exhibit positive ESG characteristics to the extent the Sub-Adviser might have anticipated.Foreign Investments: Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, auditing and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region.Investment Model: A manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. Volatility management techniques may not always be successful in reducing volatility, may not protect against market declines, and may limit the Fund’s participation in market gains, negatively impacting performance even during periods when the market is rising. During sudden or significant market rallies, such underperformance may be significant. Moreover, volatility management strategies may increase portfolio transaction costs, which may increase losses or reduce gains. The Fund’s volatility may not be lower than that of the Index during all market cycles due to market factors.Funds that are actively managed, in whole or in part, according to a quantitative investment model can perform differently from the market as a whole 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. There is no guarantee that the use of these investment models will result in effective investment decisions for the Fund.Liquidity: If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Fund to the risk that the price at which it sells illiquid securities will be less than the price at which they were valued when held by the Fund. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund.Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas 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 Capitalization: Stocks fall into three broad market capitalization categories - large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with larger companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.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 U.S. Wars, terrorism, global health crises and pandemics, and other geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and world economies and markets generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, and a substantial economic downturn in economies throughout the world. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. Those events as well as other changes in 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 investments of the Fund and the Fund. Any of these occurrences could disrupt the operations of the Fund and of the Fund’s service providers.Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund. The investment policies of the other investment companies may not be the same as those of the Fund; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Fund is typically subject.Real Estate Companies and Real Estate Investment Trusts (“REITs”): 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, and operating expenses in addition to terrorist attacks, war, or other acts that destroy real property. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.Securities Lending: Securities lending involves two primary risks: “ investment risk ” and “ borrower default risk. ” When lending securities, the Fund will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks.An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the changes in the Fund's performance from year to year, and the table compares the Fund's performance to the performance of a broad-based securities market index/indices for the same period. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund's Class A shares. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. Performance for other share classes would differ to the extent they have differences in their fees and expenses. The Class R6 shares performance shown for the period prior to their inception date is the performance of Class I shares without adjustment for any differences in the expenses between the two classes. If adjusted for such differences, returns would be different.Because Class T shares of the Fund had not commenced operations as of the calendar year ended December 31, 2021, no performance information for Class T shares is provided below.The Fund’s performance prior to December 31, 2020 reflects returns achieved pursuant to different principal investment strategies. The Fund’s performance prior to May 1, 2018 reflects returns achieved pursuant to different principal investment strategies. The Fund’s performance prior to May 1, 2016 reflects returns achieved pursuant to different principal investment strategies. The Fund’s performance prior to December 1, 2014 reflects returns achieved pursuant to different principal investment strategies. The Fund’s performance prior to November 14, 2012 reflects returns achieved by a different sub-adviser and pursuant to different principal investment strategies. If the Fund’s current sub-adviser and strategies had been in place for the prior periods, the performance information shown would have been different.

[1] A contingent deferred sales charge of 1.00% is assessed on certain redemptions of Class A shares made within 18 months after purchase where no initial sales charge was paid at the time of purchase as part of an investment of $1 million or more.

[2] The adviser and distributor are contractually obligated to limit expenses to 0.85%, 1.60%, 0.60%, 0.57%, 0.85%, and 0.60% for Class A, Class C, Class I, Class R6, Class T, and Class W shares, respectively, through March 1, 2023. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and Acquired Fund Fees and Expenses. This limitation is subject to possible recoupment by the adviser and distributor within 36 months of the waiver or reimbursement. Termination or modification of this obligation requires approval by the Fund’s board.

[3] The index returns include the reinvestment of dividends and distributions net of withholding taxes, but do not reflect fees, brokerage commissions, or other expenses.
