Fixed Income Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Fixed Income Securities Risk. Investment in fixed income securities involves a variety of risks, including that: an issuer or guarantor of a security will be unable or unwilling to pay obligations when due; due to decreases in liquidity, the Portfolio may be unable to sell its securities holdings within a reasonable time at the price it values the security or at any price; and the Portfolio’s investment may decrease in value when interest rates rise. Volatility in interest rates and in fixed income markets may increase the risk that the Portfolio’s investment in fixed income securities will go down in value. To the extent rates increase substantially and/or rapidly, a Portfolio may be subject to significant losses if it has significant investments in fixed income investments. Changes in interest rates may also affect the liquidity of the Portfolio’s investments in fixed income securities.
Interest Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Interest Rate Risk. The value of your investment may go down when interest rates rise. A rise in interest rates tends to have a greater impact on the prices of longer term or duration securities. When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Portfolio may be required to reinvest the proceeds at a lower interest rate. This is referred to as “prepayment risk.” When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Portfolio's holdings may fall sharply. This is referred to as “extension risk.” As interest rates rise, the value of fixed income investments typically decreases and there is risk that rates across the financial system also may rise. To the extent rates increase substantially and/or rapidly, a Portfolio with significant investment in fixed income investments may be subject to significant losses. The Portfolio may lose money if short-term or long-term interest rates rise sharply or in a manner not anticipated by the subadviser. Decreases in interest rates create the potential for a decrease in income earned by a Portfolio. During periods of very low or negative interest rates, the Portfolio may be unable to maintain positive returns. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from Portfolio performance.
Yield Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Yield Risk. The amount of income received by a Portfolio will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low, the Portfolio’s expenses could absorb all or a significant portion of the Portfolio’s income. If interest rates increase, the Portfolio’s yield may not increase proportionately. For example, the Portfolio’s investment manager may discontinue any temporary voluntary fee limitation.
Credit Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Credit Risk. This is the risk that the issuer, the guarantor, or the insurer of a fixed income security, the counterparty to an investment or derivatives contract, or obligor of an obligation underlying an asset-backed security may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Litigation, legislation or other political events, business or economic conditions, or the bankruptcy of the issuer could have a significant effect on an issuer’s or obligor’s ability to make payments of principal and/or interest. The lower the credit quality of a bond, the more sensitive it is to credit risk, and the credit quality of an investment can deteriorate rapidly.
Adjustable And Floating Rate Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Adjustable and Floating-Rate Securities Risk. The value of adjustable and floating-rate securities may lag behind the value of fixed-rate securities when interest rates change. Adjustable and floating rate securities generally are less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much or as quickly as interest rates in general. Conversely, adjustable and floating-rate securities generally will not increase in value as much as fixed rate debt instruments if interest rates decline. Adjustable and floating-rate securities are also subject to credit risk, market risk, and interest rate risk. In addition, the absence of an active market for these securities could make it difficult for the Portfolio to dispose of them if the issuer defaults.
Expense Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Expense Risk. The actual cost of investing in the Portfolio may be higher than the expenses shown in the “Annual Portfolio Operating Expenses” table above for a variety of reasons, including, for example, if the Portfolio’s average net assets decrease.
Market And Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market and Management Risk. Markets in which the Portfolio invests may experience volatility and go down in value, and possibly sharply and unpredictably in short periods of time. Investment techniques, risk analyses, and investment strategies, which may include quantitative models or methods, used by a subadviser in making investment decisions for the Portfolio are subject to human error and may not produce the intended or desired results. While a portfolio manager or Subadviser(s) may make efforts to control the risks associated with market changes, and may attempt to identify changes as they occur, market environment changes can be sudden and extreme. The value of the Portfolio’s investments may be negatively affected by the occurrence of domestic or global events, including war, terrorism, significant or unexpected failures, near-failures or credit downgrades of key institutions, unexpected changes in the prices of key commodities, government actions, including the threat of or actual imposition of tariffs, environmental disasters, natural disasters, sanctions, cybersecurity events, supply chain disruptions, political or civil instability, and public health emergencies, among others. Such events may reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and significantly adversely impact the economy. These events can disrupt the operations of the Portfolio and its service providers, adversely affect the liquidity and volatility of investments held by the Portfolio, and negatively impact the Portfolio’s performance. There is no guarantee that the investment objective of the Portfolio will be achieved. In periods of market volatility and/or declines, the Portfolio may experience high levels of shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices.
Prepayment Or Call Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Prepayment or Call Risk. Prepayment or call risk is the risk that issuers will prepay fixed-rate obligations held by the Portfolio when interest rates fall, forcing a Portfolio to reinvest in obligations with lower interest rates than the original obligations. Mortgage-related securities and asset-backed securities are particularly subject to prepayment risk.
Regulatory Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Regulatory Risk. The Portfolio is subject to a variety of laws and regulations which govern its operations. The Portfolio is subject to regulation by the Securities and Exchange Commission (the SEC) and the Commodity Futures Trading Commission (the CFTC). Similarly, the businesses and other issuers of the securities and other instruments in which the Portfolio invests are also subject to considerable regulation. Changes in laws and regulations may materially impact the Portfolio, a security, business, sector, or market.
US Government Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	US Government Securities Risk. US Government securities may be adversely affected by changes in interest rates, a default by, or downgrades in the credit quality rating of, the US Government, and may not be backed by the full faith and credit of the US Government.
