Dec. 31, 2025
Bank Instruments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Bank Instruments: Bank instruments include certificates of deposit, fixed time deposits, bankers’ acceptances, and other debt and deposit-type obligations issued by banks. Changes in economic, regulatory, or political conditions, or other events that affect the banking industry may have an adverse effect on bank instruments or banking institutions that serve as counterparties in transactions with the Portfolio. In the event of a bank insolvency or failure, the Portfolio may be considered a general creditor of the bank, and it might lose some or all of the funds deposited with the bank. Even where it is recognized that a bank might be in danger of insolvency or failure, the Portfolio might not be able to withdraw or transfer its money from the bank in time to avoid any adverse effects of the insolvency or failure. Volatility in the banking system may impact the viability of banking and financial services institutions. In the event of failure of any of the financial institutions where the Portfolio maintains its cash and cash equivalents, there can be no assurance that the Portfolio would be able to access uninsured funds in a timely manner or at all and the Portfolio may incur losses. Any such event could adversely affect the business, liquidity, financial position and performance of the Portfolio.
Borrowing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Borrowing: Borrowing creates leverage, which may increase expenses and increase the impact of the Portfolio’s other risks. Borrowing may exaggerate any increase or decrease in the Portfolio’s net asset value causing the Portfolio to be more volatile than a fund that does not borrow. Borrowing for investment purposes is considered to be speculative and may result in losses to the Portfolio.
Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Company: The price of a company’s stock could decline or underperform for many reasons, including, among others, poor management, financial problems, reduced demand for the company’s goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit: The Portfolio could lose money if the issuer or guarantor of a debt instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services, or otherwise) as unable or unwilling, to meet its financial obligations. Asset-backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.
Credit Default Swaps Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit Default Swaps: The Portfolio may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a credit default swap is generally obligated to pay the seller an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default, on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount if the swap is cash settled. As a seller of a credit default swap, the Portfolio would effectively add leverage to its portfolio because, in addition to its total net assets, the Portfolio would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity and leveraging risks, and the risk that the swap may not correlate with its reference obligation as expected. Certain standardized credit default swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that it will achieve that result, and in the meantime, central clearing and related requirements expose the Portfolio to different kinds of costs and risks. In addition, credit default swaps expose the Portfolio to the risk of improper valuation.
Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency: To the extent that the Portfolio invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Portfolio through foreign currency exchange transactions.
Derivative Instruments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying asset, reference rate, or index, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Portfolio. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Portfolio and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Portfolio may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the asset, reference rate, or index being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment.
Environmental Social and Governance Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Environmental, Social, and Governance (Fixed Income): The Sub-Adviser’s consideration of ESG factors in selecting investments for the Portfolio is based on information that is not standardized, some of which can be qualitative and subjective by nature. The Sub-Adviser’s assessment of ESG factors in respect of obligations of an issuer may rely on third-party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of the Portfolio’s assets that will be invested in obligations of issuers that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may choose not to invest in obligations of issuers that compare favorably to obligations of other issuers on the basis of ESG factors. It is possible that the Portfolio will have less exposure to obligations of certain issuers due to the Sub-Adviser’s assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser, which includes its consideration of ESG factors, when available, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.
Foreign Non US Investments Developing and Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign (Non-U.S.) Investments: Investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions (or the threat of new or modified sanctions) or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other debt instruments; conversely, values generally rise as market interest rates fall. Interest rate risk is generally greater for debt instruments than floating-rate instruments. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is to changes in market interest rates. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. The U.S. Federal Reserve Board recently lowered interest rates following a period of consistent rate increases. Declining market interest rates increase the likelihood that debt instruments will be pre-paid. Rising market interest rates have unpredictable effects on the markets and may expose debt and related markets to heightened volatility. To the extent that the Portfolio invests in debt instruments, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Portfolio to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in debt markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in debt markets. Fiscal, economic, monetary, or other governmental policies or measures have in the past, and may in the future, cause or exacerbate risks associated with interest rates, including changes in interest rates. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose debt and related markets to heightened volatility. In the case of inverse debt instruments, the interest rate paid by the debt instruments is a floating rate, which will generally decrease when the market rate of interest to which the inverse debt instruments are indexed increases and will increase when the market rate of interest to which the inverse debt instruments are indexed decreases. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose debt and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
Investment Model Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Investment Model: The Sub-Adviser’s proprietary investment model may not adequately take into account existing or unforeseen market factors or the interaction among such factors, including changes in how such factors interact, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for the Portfolio. Portfolios that are actively managed, in whole or in part, according to a quantitative investment model (including models that utilize forms of artificial intelligence, such as machine learning) can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Technical issues in the design, development, implementation, application, and maintenance of the models (e.g., stale or inaccurate data, human error, programming or other software issues, coding errors, and technology failures) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity: If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio’s manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Portfolio to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Portfolio, which could cause the Portfolio to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress. Certain securities that are liquid when purchased may later become illiquid, particularly in times of overall economic distress or due to geopolitical events such as sanctions, trading halts, or wars. In addition, markets or securities may become illiquid quickly.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt instruments. Additionally, legislative, regulatory or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs, and impair the ability of the Portfolio to achieve its investment objectives.
Market Capitalization Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Capitalization: Stocks fall into three broad market capitalization categories: large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
Market Disruption and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Disruption and Geopolitical: The Portfolio is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, trade disputes, tariffs and other restrictions on trade or economic sanctions, rapid technological developments (such as artificial intelligence technologies), and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and global economies and markets, generally. For example, the COVID-19 pandemic resulted in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. Military action by Russia in Ukraine, the prolonged conflict between Hamas and Israel, the Iranian conflict that commenced in February 2026, and political upheaval in Venezuela have resulted, and may continue to result, in sanctions, market disruptions, declines in regional and global stock markets, unusual volatility in global commodity markets, and disruptions to energy production or transportation, including through key shipping routes, any of which could adversely affect the value of the Portfolio ' s investments, including beyond the Portfolio's direct exposure to issuers in the affected regions. The escalation or expansion of hostilities including the involvement of additional nations, could introduce further uncertainty and volatility in global energy, commodity, and financial markets. The extent and duration of these conflicts, related sanctions, and resulting market disruptions are impossible to predict but could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Portfolio’s investments. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers. Recent technological developments in, and the increasingly widespread use of, artificial intelligence, including machine learning technology and generative artificial intelligence (“AI”), may pose risks to the Portfolio. For instance, the economy may be significantly impacted by the advanced development and increased regulation of AI. As AI is used more widely, the profitability and growth of Portfolio holdings may be impacted, which could significantly impact the overall performance of the Portfolio. The legal and regulatory frameworks within which AI operates continue to rapidly evolve, and it is not possible to predict the full extent of current or future risks related thereto.
Mortgage and or Asset Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mortgage- and/or Asset-Backed Securities: Defaults on, or low credit quality or liquidity of, the underlying assets of the asset-backed (including mortgage-backed) securities may impair the value of these securities and result in losses. There may be limitations on the enforceability of any security interest or collateral granted with respect to those underlying assets, and the value of collateral may not satisfy the obligation upon default. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of debt instruments.
Municipal Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Municipal Obligations: The municipal securities market is volatile and can be affected significantly by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities. Among other risks, investments in municipal securities are subject to the risk that an issuer may delay payment, restructure its debt, or refuse to pay interest or repay principal on its debt.
Other Investment Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Other Investment Companies: The main risk of investing in other investment companies, including ETFs, is the risk that the value of an investment company’s underlying investments might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the Portfolio’s expenses. The investment policies of the other investment companies may not be the same as those of the Portfolio; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Portfolio is typically subject. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF’s shares, which could cause a material decline in the ETF’s net asset value.
Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Portfolio Turnover: A high portfolio turnover rate may increase transaction costs, which may lower the Portfolio’s performance and may increase the likelihood of capital gains distributions.
Preferred Stocks Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Preferred Stocks: Preferred stock generally has preference over common stock but is generally subordinate to debt instruments with respect to dividends and liquidation. Preferred stocks are subject to the risks associated with other types of equity securities, as well as greater credit or other risks than senior debt instruments. In addition, preferred stocks are subject to other risks, such as risks related to deferred and omitted distributions, limited voting rights, liquidity, interest rate, regulatory changes and special redemption rights.
Prepayment and Extension Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This risk is heightened in a falling market interest rate environment. Prepayment may expose the Portfolio to a lower rate of return upon reinvestment of principal. Also, if a debt instrument subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Extension risk is the risk that the issuer of a debt instrument will pay back the principal later than expected. This risk is heightened in a rising market interest rate environment. This may negatively affect performance, as the value of the debt instrument decreases when principal payments are made later than expected. Additionally, the Portfolio may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.
Restricted Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Restricted Securities: Securities that are legally restricted as to resale (such as those issued in private placements), including securities governed by Rule 144A and Regulation S, and securities that are offered in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended, are referred to as “restricted securities.” Restricted securities may be sold in private placement transactions between issuers and their purchasers and may be neither listed on an exchange nor traded in other established markets. Due to the absence of a public trading market, restricted securities may be more volatile, less liquid, and more difficult to value than publicly-traded securities. The price realized from the sale of these securities could be less than the amount originally paid or less than their fair value if they are resold in privately negotiated transactions. In addition, these securities may not be subject to disclosure and other investment protection requirements that are afforded to publicly-traded securities. Certain restricted securities represent investments in smaller, less seasoned issuers, which may involve greater risk.
Securities Lending Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Securities Lending: Securities lending involves two primary risks: “ investment risk ” and “ borrower default risk. ” When lending securities, the Portfolio will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Portfolio will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of the Portfolio’s other risks.
Sovereign Debt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Sovereign Debt: Sovereign debt is issued or guaranteed by foreign (non-U.S.) government entities. Investments in sovereign debt are subject to the risk that a government entity may delay payment, restructure its debt, or refuse to pay interest or repay principal on its sovereign debt due to cash flow problems, insufficient foreign currency reserves, political considerations, social changes, the relative size of its debt position to its economy, or its failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a government entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting amounts owed on sovereign debt, such as bankruptcy proceedings, that a government does not pay.
US Government Securities and Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] U.S. Government Securities and Obligations: U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies, or government-sponsored enterprises. U.S. government securities are subject to market risk and interest rate risk, and may be subject to varying degrees of credit risk.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You could lose money on an investment in the Portfolio.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Portfolio is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
