International Opportunities Fund Investment Risks - International Opportunities Fund	May 31, 2026
Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Management Risk. The investment style or strategy used by the Fund 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.
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.
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.
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’s investments in equity securities are 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.
European Investment Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	European Investment Risk. The Economic and Monetary Union (the EMU) of the European Union (the EU) requires compliance by member countries with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have significant adverse effects on the economies of EU member countries and the EU and Europe as a whole. Responses to these and other financial problems by European governments, central banks, and others, including austerity measures and reforms, may not produce the desired results, may limit future growth and economic recovery, or may result in social unrest, or have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets, and asset valuations around the world. A number of countries in Eastern Europe remain relatively undeveloped and can be particularly sensitive to political and economic developments. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member countries from the European Union, such as the departure of the United Kingdom (the UK), referred to as Brexit, could place the departing member’s currency and banking system under severe stress or even in jeopardy. An exit by other member countries will likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which will adversely affect the Fund’s investments.
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 are subject to illiquidity risk.
Geographic Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Geographic Risk. If the Fund invests a significant portion of its assets in issuers located in a single country, a limited number of countries, or a particular geographic region, it assumes the risk that economic, political and social conditions in those countries or that region may have a significant impact on its investment performance.
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.
Japan Exposure Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Japan Exposure Risk. The Japanese economy faces a number of long-term problems, including massive government debt, the aging and shrinking of the population, an unstable financial sector and low domestic consumption. The growth of Japan’s economy has recently lagged behind that of its Asian neighbors and other major developed economies. The Japanese economy is heavily dependent on international trade and may be adversely affected by trade tariffs, other protectionist measures, dependence on exports and international trade, increasing competition from Asia’s other low-cost emerging economies, political and social instability, regional and global conflicts and natural disasters, as well as by commodity markets fluctuations related to Japan’s limited natural resource supply.
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.
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.
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.
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.
