The following table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Portfolio. The table below does not reflect any fees and expenses associated with variable life insurance contracts and variable annuity certificates and contracts (“Contracts”), which would increase overall fees and expenses. See the Contract prospectus for a description of those fees and expenses.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other portfolios. The Example assumes that you invest $10,000 in the Portfolio for the periods indicated, that your investment has a 5% return each year, that the Portfolio’s operating expenses remain the same, and that the Expense Limitation Arrangement is not renewed. This Example does not reflect any Contract-related fees and expenses including redemption fees (if any) at the Contract level. If such fees and expenses were reflected, the total expenses would be higher. Although your actual costs may be higher or lower, based on these assumptions, whether you redeem or hold your shares, your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests at least 80% of its net assets, plus borrowings for investment purposes, in a diversified portfolio of U.S. and foreign bonds or other debt securities of varying maturities and other instruments that provide investment exposure to such debt securities, including forwards or derivatives such as options, futures contracts or swap agreements. Under normal circumstances, the Portfolio invests primarily in a diversified mix of U.S. dollar-denominated investment grade fixed income securities, particularly U.S. government securities, corporate securities and mortgage- and asset-backed securities. The Portfolio may invest in securities of any maturity. Under normal circumstances, it is expected that the average portfolio duration of the Portfolio will be within 5 years of the duration of the benchmark. As of December 31, 2024, the average duration of the benchmark, the Bloomberg U.S. Aggregate Bond Index, was 5.90 years. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates, which may increase the volatility of the security’s value and may lead to losses. As a separate measure, there is no limit on the weighted average maturity of the Portfolio’s fixed income portfolio. The Portfolio may invest in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers, including securities and instruments that are economically tied to emerging market countries. The Portfolio will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 40% of its total assets (this limitation does not apply to investment grade sovereign debt denominated in the local currency with less than 1 year remaining to maturity). The Portfolio is expected to maintain an average weighted portfolio quality of BBB- or better, which is considered investment grade, whether composed of rated securities or unrated securities deemed by the portfolio managers to be of comparable quality. The Portfolio may invest in both investment grade securities and high yield securities (“junk bonds”) subject to a maximum of 40% of its total assets in securities rated below investment grade by Standard & Poor’s Global Ratings (“S&P”), Fitch, Inc. (“Fitch”), or Moody’s Investors Service, Inc. (“Moody’s”) or, if unrated, determined by the Adviser or a sub-adviser to be of comparable quality. The below investment grade securities in which the Portfolio invests are generally rated at least CC by S&P or Fitch or at least Ca by Moody’s or, if unrated, determined by the Adviser or a sub-adviser to be of comparable quality. The Portfolio may continue to hold securities that are downgraded below these ratings (or that default) subsequent to purchase. The Portfolio does not normally invest in securities that are in default or have defaulted with respect to the payment of interest or repayment of principal, but may do so depending on market or other conditions. The Portfolio may have exposure to securities rated below CC or Ca, or to securities that are in default or have defaulted, through its investments in certain derivatives described below. The Portfolio may invest, without limitation, in forwards and derivative instruments such as options, futures contracts, structured securities or swap agreements (including total return swaps, credit default swaps and interest rate swaps), and in mortgage- and asset-backed securities, subject to applicable law and any other restrictions described in the Portfolio’s Prospectus or Statement of Additional Information. Derivatives may be used for various investment purposes, including to hedge portfolio risk, to gain exposure or to short individual securities, to earn income and enhance return, and to manage duration. The Portfolio’s investments in derivatives may involve the use of leverage because the Portfolio is not required to invest the full market value of the contract upon entering into the contract but participates in gains and losses on the full contract price. The use of derivatives also may involve the use of leverage because the heightened price sensitivity of some derivatives to market changes may magnify the Portfolio’s gain or loss. The Portfolio’s investments in derivatives may require it to maintain a percentage of its assets in cash and cash equivalent instruments to serve as margin or collateral for the Portfolio’s obligations under derivative transactions. The Portfolio may enter into foreign currency exchange transactions to hedge against currency exposure in its portfolio. The Portfolio may enter into forward currency exchange contracts and other currency derivatives, such as swaps, options and futures, to shift its investment exposure from one currency into another. This may include shifting exposure from U.S. dollars to a foreign currency, or from one foreign currency to another foreign currency. This type of strategy, sometimes known as a “cross-hedge,” will tend to reduce or eliminate exposure to the currency that is sold, and increase exposure to the currency that is purchased, much as if the Portfolio had sold a security denominated in one currency and purchased an equivalent security denominated in another. Cross-hedges are intended to protect against losses resulting from a decline in the value of the hedged currency, but will cause the Portfolio to assume the risk of fluctuations in the value of the currency it purchases, and may also limit any potential gain that might result should the value of such hedged currency increase. The Portfolio may purchase or sell securities on a when-issued, delayed delivery, or forward commitment basis. The Portfolio may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts (such as contracts for derivative instruments) or by using other investment techniques (such as buy backs or dollar rolls). The Portfolio may invest in privately placed and restricted securities (including 144A bonds), collateralized loan obligations, inflation-indexed bonds, convertible bonds, preferred securities, bank loans, and loan participations and assignments. The Portfolio may also invest in zero coupon and pay-in-kind securities. The Portfolio may engage in active and frequent trading to achieve its investment objective. Notwithstanding the foregoing, the Portfolio may receive instruments prohibited or not contemplated herein through the conversion, exchange, reorganization, corporate action or bankruptcy of an otherwise permissible investment. The Portfolio may hold or dispose of these investments at the portfolio managers’ discretion. The Adviser will generally allocate the Portfolio’s assets among three or more Sub-Advisers, each of which manages its portion of the Portfolio using different yet complementary investment strategies.
