International Growth Fund Investment Risks - International Growth Fund
May 31, 2026
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.
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. Economies and financial markets are becoming more connected, which increases the likelihood that conditions in one country or region can adversely impact issuers in different countries and regions.
Focused Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Focused Fund Risk. The Fund, because it may invest in a limited number of companies, may have more volatility in its net asset value and is considered to have more risk than a portfolio that invests in a greater number of companies because changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s net asset value. To the extent the Fund invests its assets in fewer securities, the Fund is subject to greater risk of loss if any of those securities decline in price.
Consumer Discretionary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Consumer Discretionary Risk. To the extent that the Fund invests a substantial portion of its assets in the consumer discretionary sector, the Fund will be particularly susceptible to the risks associated with companies operating in such sector(s). Companies in the consumer discretionary sector are subject to risks, including fluctuations in the performance of the overall domestic and international economy, shipment and supply chain disruptions, interest rate changes, currency exchange rates, increased competition and consumer confidence. Performance of such companies may also be adversely affected by factors such as reduced disposable household income, reduced consumer spending, and changing demographics and consumer tastes.
Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency Risk. Because the Fund’s foreign investments are generally held in foreign currencies, the Fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar. Such gains or losses may be substantial.
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. Depositary receipts may or may not be jointly sponsored by the underlying issuer. 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 may be considered to be illiquid securities.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Emerging Markets Risk. In addition to the risks associated with investments in foreign securities, emerging market securities are subject to additional risks, which cause these securities generally to be more volatile than securities of issuers located in developed countries.
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 out of favor with investors. Large-cap companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies. During periods when equity securities experience heightened volatility, such as during periods of market, economic or financial uncertainty or distress, the Fund’s investments in equity securities may be subject to heightened risks. 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.
Mid Cap Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mid-Cap Company Risk. Investing in mid-cap companies carries the risk that due to current market conditions these companies may be out of favor with investors. Stocks of mid-cap companies may be more volatile than those of larger companies due to, among other reasons, narrower product lines, more limited financial resources and fewer experienced managers.
Small Cap Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Small-Cap Company Risk. Investing in small-cap companies carries the risk that due to current market conditions these companies may be out of favor with investors. Small companies often are in the early stages of development with limited product lines, markets, or financial resources and managements lacking depth and experience, which may cause their stock prices to be more volatile than those of larger companies. Small company stocks may be less liquid yet subject to abrupt or erratic price movements. It may take a substantial period of time before the Fund realizes a gain on an investment in a small-cap company, if it realizes any gain at all.
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.
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.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity Risk. If the active trading market for certain securities becomes limited or non-existent, it can become more difficult to sell the securities at or near their perceived value. This may cause the value of such securities and the Fund’s share price to fall dramatically. Illiquidity can be caused by, among other things, a drop in overall market trading volume, an inability to find a willing buyer, or legal restrictions on the securities’ resale.
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.
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.
