Global Strategy Fund Investment Risks - Global Strategy Fund
May 31, 2026
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk. The investment style or strategy used by a subadviser and sub-subadviser may fail to produce the intended result. A subadviser and sub-subadviser’s assessment of a particular security or company may prove incorrect, resulting in losses or underperformance.
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.
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.
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.
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.
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.
Factor Based Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Factor-Based Investing Risk. With respect to a strategy that uses a factor-based process, there can be no assurance that the multi-factor selection process employed by the subadviser will enhance performance. Exposure to investment style factors may detract from performance in some market environments, which may continue for prolonged periods.
Disciplined Strategy Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Disciplined Strategy Risk. The Fund will not deviate from its equity strategy (except to the extent necessary to comply with federal tax laws or other applicable laws). If the Fund is committed to a strategy that is unsuccessful, the Fund will not meet its investment goal. Because the Fund generally will not use certain techniques available to other mutual funds to reduce stock market exposure, the Fund may be more susceptible to general market declines than other mutual funds.
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit Risk. The issuer of a fixed income security owned by the Fund may be unable to make interest or principal payments.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk. Fixed income securities may be subject to volatility due to changes in interest rates. The value of fixed-income securities may decline when interest rates go up or increase when interest rates go down. The interest earned on fixed-income securities may decline when interest rates go down or increase when interest rates go up. Duration is a measure of interest rate risk that indicates how price-sensitive a bond is to changes in interest rates. Longer-term and lower coupon bonds tend to be more sensitive to changes in interest rates. For example, a bond with a duration of three years will decrease in value by approximately 3% if interest rates increase by 1%. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility, and could negatively impact the Fund’s performance. Any future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.
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.
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. When currency forwards are used by the Fund for hedging purposes, there is a risk that due to imperfect correlations, the currency forwards will not fully hedge against adverse changes in foreign currency values or, under extreme market conditions, will not provide any hedging benefit. The successful use of currency forwards for non-hedging purposes usually depends on the portfolio managers’ ability to forecast movements in foreign currency values and may be speculative. Should these values move in unexpected ways, the Fund may not achieve the anticipated benefit from using currency forwards, and it may realize losses, which could be significant.
Foreign Sovereign Debt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Sovereign Debt Risk. Foreign sovereign debt securities are subject to the risk that a governmental entity may delay or refuse to pay interest or to repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political, social and economic considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans.
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.
Credit Default Swap Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit Default Swap Risk. A credit default swap is an agreement between two parties: a buyer of credit protection and a seller of credit protection. The buyer in a credit default swap agreement is obligated to pay the seller a periodic stream of payments over the term of the swap agreement. If no default or other designated credit event occurs, the seller of credit protection will have received a fixed rate of income throughout the term of the swap agreement. If a default or designated credit event does occur, the seller of credit protection must pay the buyer of credit protection the full value of the reference obligation. Credit default swaps increase counterparty risk when the Fund is the buyer. The absence of a central exchange or market for swap transactions has led, in some instances, to difficulties in trading and valuation, especially in the event of market disruptions. Recent legislation requires most swaps to be executed through a centralized exchange or regulated facility and be cleared through a regulated clearinghouse. The swap market could be disrupted or limited as a result of this legislation, which could adversely affect the Fund. Moreover, the establishment of a centralized exchange or market for swap transactions may not result in swaps being easier to trade or value.
Junk Bonds Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Junk Bond Risk. High yielding, high risk fixed-income securities (often referred to as “junk bonds”) may involve significantly greater credit risk, market risk and interest rate risk compared to higher rated fixed-income securities. Issuers of junk bonds are less secure financially and their securities are more sensitive to downturns in the economy. The market for junk bonds may not be as liquid as that for more highly rated securities.
Mortgage Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mortgage-Backed Securities Risk. Mortgage-backed securities are similar to other debt securities in that they are subject to credit risk and interest rate risk. Mortgage-backed securities may be issued or guaranteed by the U.S. Government, its agencies or instrumentalities or may be non-guaranteed securities issued by private issuers. These securities are also subject to the risk that issuers will prepay the principal more quickly or more slowly than expected, which could cause the Fund to invest the proceeds in less attractive investments or increase the volatility of their prices.
Asset Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Asset-Backed Securities Risk. Asset-backed securities are bonds or notes that are normally supported by a specific property. If the issuer fails to pay the interest or return the principal when the bond matures, then the issuer must give the property to the bondholders or noteholders. Examples of assets supporting asset-backed securities include credit card receivables, retail installment loans, home equity loans, auto loans, and manufactured housing loans.
Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Income Risk. Because the Fund can only distribute what it earns, the Fund’s distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.
Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Counterparty Risk. Counterparty risk is the risk that a counterparty to a security, loan or derivative held by the Fund becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties. The Fund may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding, and there may be no recovery or limited recovery in such circumstances.
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.
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.
Large Cap Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large-Cap Companies Risk. Large-cap companies tend to go in and out of favor based on market and economic conditions and tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Fund’s value may not rise as much as the value of funds that emphasize smaller capitalization 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.
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.
Money Market Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Money Market Securities Risk. An investment in the Fund is subject to the risk that the value of its investments in high-quality short-term obligations (“money market securities”) may be subject to changes in interest rates, changes in the rating of any money market security and in the ability of an issuer to make payments of interest and principal.
Currency Management Strategies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency Management Strategies Risk. Currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the subadviser expects. In addition, currency management strategies, to the extent that they reduce the Fund’s exposure to currency risks, may also reduce the Fund’s ability to benefit from favorable changes in currency exchange rates. Using currency management strategies for purposes other than hedging further increases the Fund’s exposure to foreign investment losses. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns.
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.
