International Equity Fund Investment Risks - International Equity Fund	Dec. 31, 2024
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk The risk that markets will perform poorly or that the returns from the securities in which the Fund invests will underperform returns from the general securities markets or other types of investments. Markets may experience periods of high volatility and reduced liquidity in response to governmental actions or intervention, political, economic or market developments, or other external factors, such as outbreaks of infectious illnesses or other widespread public health issues, outbreaks of war or sanctions in response to military incursions and natural disasters such as floods, droughts, fires, extreme storms, earthquakes or volcanic eruptions. During those periods, the Fund may experience high levels of shareholder redemptions, and may have to sell securities at times when the Fund would otherwise not do so, and potentially at unfavorable prices. Certain securities may be difficult to value during such periods. These risks may be heightened for fixed income securities in low interest rate environments.
Equity Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity Securities Risk Equity securities generally have greater price volatility than fixed-income securities. The market price of equity securities owned by a fund may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting the issuer, equity securities markets generally, particular industries represented in those markets or the issuer itself.
Foreign Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign Risk  Foreign securities are subject to political, regulatory, and economic risks not present in domestic investments and may exhibit more extreme changes in value than securities of U.S. companies. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. In addition, foreign companies often are not subject to the same degree of regulation as U.S. companies. Reporting, legal, accounting and auditing standards of foreign countries differ, in some cases significantly, from U.S. standards. Nationalization, expropriation or confiscatory taxation, currency blockage, political changes or diplomatic developments could adversely affect the Fund’s investments in a foreign country. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire investment. Investments in emerging market countries are likely to involve significant risks. These countries are generally more likely to experience political and economic instability.
Currency Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Currency Risk Foreign currencies may experience steady or sudden devaluation relative to the U.S. dollar or other currencies, adversely affecting the value of the Fund’s investments. The value of the Fund’s assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and restrictions or prohibitions on the repatriation of foreign currencies. Because the Fund’s net asset value is determined on the basis of U.S. dollars, if the local currency of a foreign market depreciates against the U.S. dollar, you may lose money even if the foreign market prices of the Fund’s holdings rise.
Emerging and Frontier Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Emerging and Frontier Market Risk The risk that investing in emerging and frontier markets will be subject to greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country’s dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, thinner trading markets, different clearing and settlement procedures and custodial services, and less developed legal systems than in many more developed countries. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries.
Focused Investment Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Focused Investment Risk A fund that invests a substantial portion of its assets in a particular market, industry, sector, group of industries or sectors, country, region, group of countries or asset class is subject to greater risk than a fund that invests in a more diverse investment portfolio. In addition, the value of such a fund is more susceptible to any single economic, market, political or regulatory or other occurrence affecting, for example, the particular markets, industries, regions, sectors or asset classes in which the fund is invested. This is because, for example, issuers in a particular market, industry, region, sector or asset class may react similarly to specific economic, market, regulatory, political or other developments. The particular markets, industries, regions, sectors or asset classes in which the Fund may focus its investments may change over time and the Fund may alter its focus at inopportune times.
Depositary Receipts Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Depositary Receipts Risk Depositary receipts in which the Fund may invest are receipts listed on U.S. exchanges that are issued by banks or trust companies that entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.
Derivatives Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Derivatives Risk The risk that an investment in derivatives will not perform as anticipated by the Fund’s subadviser, cannot be closed out at a favorable time or price, or will increase the Fund’s volatility; that derivatives may create investment leverage; that, when a derivative is used as a substitute for or alternative to a direct cash investment, the transaction may not provide a return that corresponds precisely with that of the cash investment; or that, when used for hedging purposes, derivatives will not provide the anticipated protection, causing the Fund to lose money on both the derivatives transaction and the exposure the Fund sought to hedge. The counterparty to a derivatives contract may be unable or unwilling to make timely settlement payments, return the Fund’s margin, or otherwise honor its obligations. Changes in regulation relating to a mutual fund’s use of derivatives and related instruments could potentially limit or impact the Fund’s ability to invest in derivatives, limit a Fund’s ability to employ certain strategies that use derivatives and adversely affect the value or performance of derivatives and the Fund.
Preferred Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Preferred Securities Risk The risk that: (i) certain preferred stocks contain provisions that allow an issuer under certain conditions to skip or defer distributions; (ii) preferred stocks may be subject to redemption, including at the issuer’s call, and, in the event of redemption, the Fund may not be able to reinvest the proceeds at comparable or favorable rates of return; (iii) preferred stocks are generally subordinated to bonds and other debt securities in an issuer’s capital structure in terms of priority for corporate income and liquidation payments; and (iv) preferred stocks may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities.
Convertible Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Convertible Securities Risk Convertible securities may be subordinate to other debt securities issued by the same issuer. Issuers of convertible securities are often not as strong financially as issuers with higher credit ratings. Convertible securities typically provide yields lower than comparable non-convertible securities. Their values may be more volatile than those of non-convertible securities, reflecting changes in the values of the securities into which they are convertible.
Issuer Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Issuer Risk The risk that the value of a security may decline because of adverse events or circumstances that directly relate to the issuer.
Manager Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Manager Risk  The risk that the subadviser's decisions, including security selection, will cause the Fund to underperform relative to the Fund’s peers. There can be no assurance that the subadviser’s investment techniques and decisions will produce the desired results. The Fund’s ability to achieve its investment objective is dependent upon the subadviser’s ability to identify profitable investment opportunities for the Fund. The past experience of the portfolio manager(s), including with other strategies and funds, does not guarantee future results for the Fund.
Risk Lose Money [Member]
