Large Cap Core Fund Investment Risks - Large Cap Core Fund
May 31, 2026
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity Securities Risk. The Fund invests primarily in equity securities and is therefore subject to the risk that stock prices will fall and may underperform other asset classes. Individual stock prices fluctuate from day-to-day and may decline significantly. The prices of individual stocks may be negatively affected by poor company results or other factors affecting individual prices, as well as industry and/or economic trends and developments affecting industries or the securities market as a whole.
Large Cap Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large-Cap Companies Risk. Investing primarily in large-cap companies carries the risk that due to current market conditions these companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rate of successful smaller companies, particularly during extended periods of economic expansion.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk. The investment style or strategy used by a subadviser may fail to produce the intended result. A subadviser’s assessment of a particular security or company may prove incorrect, resulting in losses or underperformance.
Dividend paying Stocks Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Dividend-paying Stocks Risk. There is no guarantee that the issuers of the stocks held by the Fund will declare dividends in the future or that, if dividends are declared, they will remain at their current levels or increase over time. Dividend-paying stocks may not participate in a broad market advance to the same degree as other stocks, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend.
Depositary Receipts Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Depositary Receipts Risk. Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. The issuers of unsponsored depositary receipts are not obligated to disclose information that is considered material in the United States. Therefore, there may be less information available regarding the issuers and there may not be a correlation between such information and the market value of the depositary receipts. Certain depositary receipts are not listed on an exchange and therefore are subject to illiquidity risk.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. The prices of derivatives may move in unexpected ways due to the use of leverage and other factors and may result in increased volatility or losses. The Fund may not be able to terminate or sell derivative positions, and a liquid secondary market may not always exist for derivative positions.
Futures Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Futures Risk. A futures contract is considered a derivative because it derives its value from the price of the underlying currency, security or financial index. The prices of futures contracts can be volatile and futures contracts may lack liquidity. In addition, there may be imperfect or even negative correlation between the price of a futures contract and the price of the underlying currency, security or financial index.
ESG Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ESG Investment Risk. The portfolio manager(s) may utilize ESG criteria, integrate ESG considerations and/or use related analyses to select investments for the Fund. These strategies may impact the Fund’s performance, including relative to similar funds that do not adhere to such ESG criteria, ESG integration and/or related analyses as part of the investment process. Additionally, the Fund’s adherence to these strategies in connection with identifying and selecting investments may require subjective and qualitative analysis and may be more difficult if data about a particular company or market is limited, such as with respect to issuers in emerging markets countries. The Fund may invest in companies that do not reflect the beliefs and values of any particular investor. Socially responsible norms differ by country and region, and a company’s ESG practices or a portfolio manager’s assessment of such may change over time. ESG characteristics may not be the only factors considered in selecting investments and as a result, the Fund’s investments may not have favorable ESG characteristics or high ESG ratings.
Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Investment Risk. Investment in foreign securities involves risks due to several factors, such as illiquidity, the lack of public information, changes in the exchange rates between foreign currencies and the U.S. dollar, unfavorable political, social and legal developments, or economic and financial instability. Foreign companies are not subject to the U.S. accounting and financial reporting standards and may have riskier settlement procedures. U.S. investments that are denominated in foreign currencies or that are traded in foreign markets, or securities of U.S. companies that have significant foreign operations may be subject to foreign investment risk.
Growth Style Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Growth Style Risk. Generally, “growth” stocks are stocks of companies that have anticipated earnings ranging from steady to accelerated growth. Many investors buy growth stocks because of anticipated superior earnings growth, but earnings disappointments often result in sharp price declines. Growth companies usually invest a high portion of earnings in their own businesses so their stocks may lack the dividends that can cushion share prices in a down market. In addition, the value of growth stocks may be more sensitive to changes in current or expected earnings than the value of other stocks, because growth stocks trade at higher prices relative to current earnings.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The Fund’s share price can fall because of weakness in the broad market, a particular industry, or specific holdings or due to adverse social, political or economic developments here or abroad, changes in investor psychology, technological disruptions, or heavy institutional selling and other conditions or events (including, for example, military confrontations, war, terrorism, trade wars, disease/virus, outbreaks and epidemics). The prices of individual securities may fluctuate, sometimes dramatically, from day to day. The prices of stocks and other equity securities tend to be more volatile than those of fixed-income securities.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Sector Risk. Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the risk that securities of companies within specific sectors of the economy can perform differently than the overall market. This may be due to changes in such things as the regulatory or competitive environment or to changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain sectors than others, the Fund’s performance may be more susceptible to any developments which affect those sectors emphasized by the Fund.
Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Technology Sector Risk. Technology stocks historically have experienced unusually wide price swings. Earnings disappointments and intense competition for market share can result in sharp declines in the prices of technology stocks.
Securities Lending Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Securities Lending Risk. Engaging in securities lending could increase the market and credit risk for Fund investments. The Fund may lose money if it does not recover borrowed securities, the value of the collateral falls, or the value of investments made with cash collateral declines. The Fund’s loans will be collateralized by securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities, which subjects the Fund to the credit risk of the U.S. Government or the issuing federal agency or instrumentality. If the value of either the cash collateral or the Fund’s investments of the cash collateral falls below the amount owed to a borrower, the Fund also may incur losses that exceed the amount it earned on lending the security. Securities lending also involves the risks of delay in receiving additional collateral or possible loss of rights in the collateral if the borrower fails. Another risk of securities lending is the risk that the loaned portfolio securities may not be available to the Fund on a timely basis and the Fund may therefore lose the opportunity to sell the securities at a desirable price.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] If the value of the assets of the Fund goes down, you could lose money.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] Shares of the Fund are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation.
