| 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 example, affect the fund’s performance. During its 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. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be: | ||

| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The fund seeks to generate capital appreciation by investing at least 80% of net assets (plus borrowings for investment purposes) in a diversified portfolio of equity securities. Under normal market conditions, at least 40% of the value of the fund’s net assets will be invested in securities of issuers domiciled outside of the United States (“Foreign Companies”), unless the manager deems market conditions and/or company valuations to be less favorable to Foreign Companies, in which case, the fund will invest at least 30% of the value of its net assets in Foreign Companies. Foreign Companies include issuers domiciled in emerging markets and securities of foreign issuers that trade on U.S. exchanges. Equity securities include common and preferred stocks and their equivalents, including depositary receipts, warrants, rights, and convertible securities. The fund may invest in securities of any market-capitalization. The manager considers environmental, social, and/or governance (ESG) factors, alongside other relevant factors, as part of its investment process. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The ESG characteristics utilized in the fund’s investment process may change over time and one or more characteristics may not be relevant with respect to all issuers that are eligible fund investments. The manager employs an unconstrained, bottom-up stock selection process based on fundamental research to attempt to identify undervalued companies that exhibit attractive valuations, solid business franchises, sustainable margins/cash flow, disciplined capital allocation, strong management teams, and strong balance sheets. The manager considers diversification benefits and liquidity of the security in making investment decisions. | ||

| Class NAV | Global Equity Fund | Risk Lose Money [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money. | ||
| Class NAV | Global Equity Fund | Risk Not Insured Depository Institution [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||
| Class NAV | Global Equity 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, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate. | ||
| Class NAV | Global Equity Fund | Emerging Markets Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Emerging-market risk. The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries. | ||
| Class NAV | Global Equity Fund | Equity Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Equity securities risk. The price of equity securities may decline due to changes in a company’s financial condition or overall market conditions. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole. | ||
| Class NAV | Global Equity Fund | ESG Integration Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | ESG integration risk. The manager considers ESG factors that it deems relevant or additive, along with other material factors and analysis, when managing the fund. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The manager may consider these ESG factors on all or a meaningful portion of the fund’s investments. Incorporating ESG criteria and making investment decisions based on certain ESG characteristics, as determined by the manager, carries the risk that the fund may perform differently, including underperforming, funds that do not utilize ESG criteria, or funds that utilize different ESG criteria. | ||
| Class NAV | Global Equity Fund | Foreign Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Foreign securities risk. Less information may be publicly available regarding foreign issuers, including foreign government issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk. | ||
| Class NAV | Global Equity Fund | Large Company Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Large company risk. Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole. | ||
| Class NAV | Global Equity Fund | Liquidity Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity risk. The extent (if at all) to which a security may be sold without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. | ||
| Class NAV | Global Equity Fund | Operational And Cybersecurity Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Operational and cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund’s securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes. | ||
| Class NAV | Global Equity Fund | Preferred And Convertible Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Preferred and convertible securities risk. Preferred stock dividends are payable only if declared by the issuer’s board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock’s value can depend heavily upon the underlying common stock’s value. | ||
| Class NAV | Global Equity Fund | Small And Mid Sized Company Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Small and mid-sized company risk. Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole. | ||
| Class NAV | Global Equity Fund | Warrants Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Warrants risk. The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date. | ||
