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 any borrowings for investment purposes, in fixed income securities. For purposes of this investment policy, fixed income securities include direct and indirect investments in fixed income securities and investments in other investment companies (including investment companies advised by the Sub-Adviser) and financial instruments that derive their value from such securities. The Portfolio’s investments in fixed income securities include, but are not limited to, securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or sponsored corporations; mortgage-backed securities; asset-backed securities; foreign and domestic corporate bonds; floating or variable rate obligations (including inverse floater collateralized mortgage obligations); bank loans; 144A bonds; fixed income securities issued by corporations and governments in foreign countries including emerging markets issuers and U.S. dollar-denominated securities of non-U.S. issuers; securities issued by municipalities; and other securities bearing fixed interest rates of any maturity. The Portfolio may invest up to 40% of its assets in below investment grade securities (commonly known as “junk bonds”). Such investments may include debt obligations of distressed companies, including companies that are close to or in default. The Sub-Adviser allocates investments in below investment grade securities broadly by industry and issuer in an attempt to reduce the impact on the Portfolio of negative events affecting an industry or issuer. Securities below investment grade include those securities rated Ba1 or lower by Moody’s Investors Service, Inc. (“Moody’s”) or BB+ or lower by Fitch Ratings Ltd. (“Fitch”) or by Standard & Poor’s Global Ratings (“S&P”) or, if unrated, deemed to be of comparable quality by the Adviser or Sub-Adviser. The Portfolio may invest in mortgage-backed or other asset-backed securities of any credit rating or credit quality without regard to the 40% limitation described above. The Portfolio also may invest in inverse floaters, interest-only and principal-only securities. The Portfolio may invest in senior bank loans and assignments, including through investments in other investment companies advised by the Sub-Adviser. In addition, the Portfolio may invest in collateralized loan obligations (“CLOs”), provided that investments (1) in CLOs and other vehicles considered to be “private funds” under Rule 12d1-4 under the Investment Company Act of 1940, as amended, and (2) in other covered investment companies do not exceed, in the aggregate, 10% of the Portfolio’s assets at the time of a new investment in such instrument. The Sub-Adviser actively manages the Portfolio’s asset class exposure using a top-down approach, which involves using fundamental research regarding the investment characteristics of each sector (such as risk, volatility, relative value, and the potential for growth and income), as well as the Sub-Adviser’s outlook for the economy and financial markets as a whole. Primary sectors include government/municipals, high yield, global developed credit, international sovereign debt, emerging markets, and mortgage- and asset-backed. The Sub-Adviser will gradually rotate portfolio assets among sectors in various markets using a long-term approach to attempt to maximize return. Individual securities within asset classes are selected using a bottom-up approach, which involves an analysis of each individual issuer’s creditworthiness. In managing the Portfolio, the Sub-Adviser uses a controlled risk approach, which includes consideration of: • Security selection within a given asset class • Relative performance of the various market sectors and asset classes • The rates offered by bonds at different maturities • Fluctuations in the overall level of interest rates The Sub-Adviser also monitors the duration of the securities held by the Portfolio to seek to mitigate exposure to interest rate risk. 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. Under normal circumstances, the Sub-Adviser seeks to maintain an investment portfolio with a weighted average effective duration of no less than two years and no more than eight years. The duration of the Portfolio’s investments may vary materially from its target, from time to time, and there is no assurance that the duration of the Portfolio’s investments will meet its target. The Portfolio may use futures, including U.S. Treasury futures, to manage the Portfolio's duration and yield curve exposure. Additionally, the Portfolio may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis, including United States agency mortgage-backed securities that forward-settle (e.g., “To Be Announced” Securities (“TBAs”)). 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 or by using other investment techniques (such as buy backs or dollar rolls), which may create investment leverage. Portfolio securities may be sold at any time. The Sub-Adviser may sell a security for a variety of reasons, including but not limited to, when the Sub-Adviser perceives deterioration in the credit fundamentals of the issuer, believes there are negative macro political considerations that may affect the issuer, determines to take advantage of what the Sub-Adviser believes is a better investment opportunity, or the individual security has reached the Sub-Adviser’s sell target. The Portfolio may engage in active and frequent trading of portfolio securities to achieve its investment objective.

Risk [Text Block]

Market Risk — The Portfolio is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect Portfolio performance. Securities markets also may experience long periods of decline in value. The value of a security can be more volatile than the market as a whole and can perform differently from the market as a whole. Any issuer of securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by a variety of factors, such as poor management decisions; reduced demand for the issuer’s goods or services; competitive pressures; negative perception in the marketplace; loss of major customers; strategic initiatives such as mergers or acquisitions and the market response to any such initiatives; and the historical and prospective earnings of the issuer. The value of a security also may decline due to general market conditions, such as real or perceived adverse economic or political conditions, inflation rates and/or investor expectations concerning such rates, changes in interest rates, recessions, or adverse investor sentiment generally. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Even when securities markets perform well, there can be no assurance that the investments held by the Portfolio will increase in value along with the broader market. Changes in the financial condition of (or other event affecting) a single issuer can impact an individual sector or industry, or the securities markets as a whole. The value of a security also may decline due to factors that affect a particular sector or industry, such as tariffs, labor shortages, or increased production costs and competitive conditions within the sector or industry. Geopolitical events, including acts of terrorism, tensions, war or other open conflicts between nations, or political or economic dysfunction within nations that are global economic powers or major oil or other commodities producers, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. World markets, or those in a particular region, may all react in similar fashion to economic, political or other developments. Events such as environmental and natural disasters or other catastrophes, public health crises (such as epidemics and pandemics), social unrest, and cybersecurity incidents, and governments’ reactions (or failure to react) to such events, could cause uncertainty in the markets and may adversely affect the performance of the global economy. Impacts from climate change may include significant risks to global financial assets and economic growth. The extent and duration of such events and resulting market disruptions could be substantial and could magnify the impact of other risks to the Portfolio. The value and liquidity of the Portfolio’s investments may be negatively affected by developments in other countries and regions, whether or not the Portfolio invests in securities of issuers located in or with significant exposure to the countries or regions directly affected. Changes in government or central bank policies, changes in existing laws and regulations, and political, diplomatic and other events within the United States and abroad could cause uncertainty in the markets, may affect investor and consumer confidence, and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. High public debt and deficits in the United States and other countries create ongoing systemic and market risks and policymaking uncertainty and may negatively affect economic conditions and the values of markets, sectors and companies in which the Portfolio invests. In addition, markets and market participants are increasingly reliant on information data systems. Inaccurate data, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large. Furthermore, impacts from the rapidly growing use of artificial intelligence technologies, including by market participants, may include significant risks to global financial markets.

Credit Risk — The Portfolio is subject to the risk that the issuer or guarantor of a fixed income security, or the counterparty to a transaction, is unable or unwilling, or is perceived as unable or unwilling, to make timely interest or principal payments or otherwise honor its obligations, or defaults completely, which may cause the Portfolio’s holdings to lose value. The downgrade of a security’s credit rating may decrease its value. Lower credit quality also may lead to greater volatility in the price of a security and may negatively affect a security’s liquidity. The credit quality of a security can deteriorate suddenly and rapidly. The Portfolio may experience a significant or complete loss on a fixed income security or a transaction.

Mortgage-Related and Other Asset-Backed Securities Risk — Declines in the credit quality of and defaults by the issuers of mortgage-related and other asset-backed securities or instability in the markets for such securities may decrease the value of such securities, which could result in losses to the Portfolio, and may reduce the liquidity of such securities and make such securities more difficult to purchase or sell at an advantageous time and price. In addition, borrowers may default on the obligations that underlie mortgage-related and other asset-backed securities. The risk of defaults by borrowers generally is greater during times of rising interest rates and/or unemployment rates. The impairment (or loss) of the value of collateral or other assets underlying mortgage-related and other asset-backed securities will result in a reduction in the value of the securities. Certain collateral may be difficult to locate in the event of default, or may be lost, and recoveries of depreciated or damaged collateral may not fully cover payments due on such collateral. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk. Furthermore, mortgage-related and other asset-backed securities typically provide the issuer with the right to prepay the security prior to maturity. During periods of rising interest rates, the rate of prepayments tends to decrease because borrowers are less likely to prepay debt (such as mortgage debt or automobile loans). Slower than expected payments can extend the average lives of mortgage-related and other asset-backed securities, and this may “lock in” a below market interest rate and increase the security’s duration and interest rate sensitivity, which may increase the volatility of the security’s value and may lead to losses. During periods of falling interest rates, the rate of prepayments tends to increase because borrowers are more likely to pay off debt and refinance at the lower interest rates then available. Unscheduled prepayments shorten the average lives of mortgage-related and other asset-backed securities and may result in the Portfolio’s having to reinvest the proceeds of the prepayments at lower interest rates, thereby reducing the Portfolio’s income. Mortgage-backed securities issued in the form of collateralized mortgage obligations (“CMOs”) are collateralized by mortgage loans or mortgage pass-through securities. In periods of supply and demand imbalances in the market for CMOs or in periods of sharp interest rate movements, the prices of CMOs may fluctuate to a greater extent than would be expected from interest rate movements alone. CMOs and other mortgage-backed securities may be structured similarly to collateralized debt obligations and may be subject to similar risks.

Non-Investment Grade Securities Risk — Bonds rated below BBB by Standard & Poor’s Global Ratings or Fitch Ratings, Ltd. or below Baa by Moody’s Investors Service, Inc. (or, if unrated, determined by the investment manager to be of comparable quality) are speculative in nature and are subject to additional risk factors such as increased possibility of default, illiquidity of the security, and changes in value based on changes in interest rates. Non-investment grade bonds, sometimes referred to as “junk bonds,” are usually issued by companies without long track records of sales and earnings, or by those companies with questionable credit strength. The creditworthiness of issuers of non-investment grade debt securities may be more complex to analyze than that of issuers of investment grade debt securities, and reliance on credit ratings may present additional risks.

U.S. Government Securities Risk — Although the Portfolio may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Portfolio itself and do not guarantee the market prices of the securities. Securities issued by the U.S. Treasury or other agencies and instrumentalities of the U.S. government may decline in value as a result of, among other things, changes in interest rates, political events in the United States, international developments, including strained relations with foreign countries, and changes in the credit rating of, or investor perceptions regarding the creditworthiness of, the U.S. government. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Securities not backed by the full faith and credit of the U.S. Treasury involve greater credit risk than investments in other types of U.S. government securities.

Portfolio Management Risk — The Portfolio is subject to the risk that strategies used by an investment manager and its securities selections fail to produce the intended results. An investment manager’s judgments or decisions about the quality, relative yield or value of, or market trends affecting, a particular security or issuer, industry, sector, region or market segment, or about the economy or interest rates, may be incorrect or otherwise may not produce the intended results, which may result in losses to the Portfolio. In addition, many processes used in Portfolio management, including security selection, rely, in whole or in part, on the use of various technologies. The Portfolio may suffer losses if there are imperfections, errors or limitations in the quantitative, analytic or other tools, resources, information and data used, or the analyses employed or relied on, by an investment manager, or if such tools, resources, information or data are used incorrectly, fail to produce the desired results, or otherwise do not work as intended. There can be no assurance that the use of these technologies will result in effective investment decisions for the Portfolio. In addition, the Portfolio could experience losses if an investment manager’s judgments about the risks associated with the Portfolio’s investment program prove to be incorrect.

Distressed Companies Risk — Debt obligations of distressed companies typically are unrated, lower-rated or close to default. In certain periods, there may be little or no liquidity in the markets for these securities. In addition, the prices of such securities may be subject to periods of abrupt and erratic market movements and above-average price volatility, and it may be difficult to value such securities. The Portfolio may lose a substantial portion or all of its investment in such securities. If the issuer of a security held by the Portfolio defaults, the Portfolio may experience a significant or complete loss on the security. Securities tend to lose much of their value before the issuer defaults.

Inverse Floaters Risk — Inverse floaters are securities with a floating or variable rate of interest. Inverse floaters have interest rates that tend to move in the opposite direction as the specified market rates or indices and may exhibit substantially greater price volatility than fixed rate obligations having similar credit quality, redemption provisions and maturity. Inverse floater collateralized mortgage obligations (“CMOs”) exhibit greater price volatility than the majority of mortgage-related securities. In addition, some inverse floater CMOs exhibit extreme sensitivity to changes in prepayments. As a result, the yield to maturity of an inverse floater CMO is sensitive not only to changes in interest rates but also to changes in prepayment rates on the related underlying mortgage assets. Inverse floaters typically involve leverage, which can magnify the Portfolio’s losses.

Leveraging Risk — When the Portfolio leverages its holdings, the value of an investment in the Portfolio will be more volatile and all other risks will tend to be compounded. Investments that create leverage can result in losses to the Portfolio that exceed the amount originally invested and may accelerate the rate of losses (some of which may be sudden or substantial). For certain investments that create leverage, relatively small market fluctuations can result in large changes in the value of such investments. There can be no assurance that the Portfolio’s use of any leverage will be successful.

Loan Risk — A bank loan represents an interest in a loan or other direct indebtedness that entitles the acquirer of such interest to payments of interest, principal and/or other amounts due under the structure of the loan. Loan interests are subject to liquidity risk, prepayment risk, extension risk, the risk of subordination to other creditors, restrictions on resale, and the lack of a regular trading market and publicly available information. Loan interests may be difficult to value and may have extended trade settlement periods. As a result, the proceeds from the sale of a loan may not be available to make additional investments or to meet redemption obligations until potentially a substantial period after the sale of the loan. The extended trade settlement periods could force the Portfolio to liquidate other securities to meet redemptions and may present a risk that the Portfolio may incur losses in order to timely honor redemptions. There is a risk that the value of any collateral securing a loan in which the Portfolio has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. In the event the borrower defaults, the Portfolio’s access to the collateral may be limited or delayed by bankruptcy or other insolvency laws. Loans may not be considered “securities,” and purchasers, such as the Portfolio, therefore may not have the benefit of the anti-fraud protections of the federal securities laws. To the extent that the Portfolio invests in loan participations and assignments, it is subject to the risk that the financial institution acting as agent for all interests in a loan might fail financially. It is also possible that the Portfolio could be held liable, or may be called upon to fulfill other obligations, as a co-lender.

Privately Placed and Other Restricted Securities Risk — Restricted securities, which include privately placed securities, are securities that cannot be offered for public resale unless registered under the applicable securities laws or that have a contractual restriction that prohibits or limits their resale. Before they are registered, such securities may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. Difficulty in selling securities may result in a loss or be costly to the Portfolio. Rule 144A is designed to facilitate efficient trading among institutional investors by permitting the sale of certain unregistered securities to qualified institutional buyers. To the extent restricted securities held by the Portfolio qualify under Rule 144A and an institutional market develops for those securities, the Portfolio likely will be able to dispose of the securities without registering them. To the extent that institutional buyers become, for a time, uninterested in purchasing these securities, investing in Rule 144A securities could increase the level of the Portfolio’s illiquidity. The Adviser or Sub-Adviser may determine that certain securities qualified for trading under Rule 144A are liquid. Where registration of a security is required, the Portfolio may be obligated to pay all or part of the registration expenses, and a considerable period may elapse between the time the Portfolio desires to sell(and therefore decides to seek registration of) the security, and the time the Portfolio may be permitted to sell the security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Portfolio might obtain a less favorable price than prevailed when it desired to sell. The risk that securities may not be sold for the price at which the Portfolio is carrying them is greater with respect to restricted securities than it is with respect to registered securities. The illiquidity of the market, as well as the lack of publicly available information regarding these securities, also may make it difficult to determine a fair value for certain securities for purposes of computing the Portfolio’s net asset value.

Risks of Investing in Other Investment Companies — When the Portfolio invests in other investment companies, it will indirectly bear its proportionate share of the fees and expenses incurred by those investment companies. These fees and expenses are in addition to the advisory fees and other expenses that the Portfolio and its shareholders bear directly in connection with the Portfolio’s own operations. As a result, the Portfolio’s shareholders will be subject to two layers of fees and expenses with respect to investments in the Portfolio. The cost of investing in the Portfolio, therefore, may be higher than the cost of investing in a mutual fund that invests directly in individual stocks and bonds. In addition, the Portfolio’s net asset value is subject to fluctuations in the net asset values of the other investment companies in which it invests. The Portfolio is also subject to the risks associated with the securities or other investments in which the other investment companies invest, and the ability of the Portfolio to meet its investment objective will depend, to a significant degree, on the ability of the other investment companies to meet their respective investment objectives.

When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Portfolio commits to purchase will decline in value prior to its delivery. This risk is in addition to the risk that the Portfolio’s other assets will decline in value. Therefore, these transactions can have a leverage-like effect on the Portfolio and increase the Portfolio’s overall investment exposure. There also is the risk that the security will not be issued or that the other party to the transaction will fail to complete the sale or purchase of the security. If this occurs, the Portfolio may lose the opportunity to purchase or sell the security at the agreed upon price and may forgo any gain in the security’s price.
