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 market conditions, the Portfolio invests at least 80% of its net assets, plus borrowings for investment purposes, in debt securities.The Portfolio uses a strategy that is commonly referred to as an index strategy. In seeking to achieve the Portfolio’s investment objective, the Sub-Adviser generally will employ a stratified sampling approach to build a portfolio whose broad characteristics match those of the Corporate Bond Index, which means that the Portfolio is not required to purchase all of the securities represented in the Index. A stratified sampling approach seeks to match the return and characteristics of a particular index without having to purchase every security in that index by selecting a representative sample of securities for the Portfolio based on the characteristics of the index and the particular securities included therein. With respect to the Corporate Bond Index, such characteristics may include interest rate sensitivity, credit quality and sector diversification.Individual securities holdings may differ from those of the Corporate Bond Index, and the Portfolio may not track the performance of the Index due to expenses and transaction costs, the size and frequency of cash flow into and out of the Portfolio, and differences between how and when the Portfolio and the Index are valued.The Corporate Bond Index measures the performance of U.S. investment grade, taxable corporate bonds with maturities between 5 and 10 years that have $300 million or more of outstanding face value. The securities in the Index must be U.S. dollar-denominated and must be fixed-rate. The Index includes securities publicly issued by U.S. and non-U.S. industrial, utility, and financial companies. The Index is rebalanced monthly, and its components are weighted based on market value, taking into account the component security’s price, accrued interest and par amount outstanding. Securities may be added to or removed from the Index in connection with the month-end rebalancing process. As of December 31, 2022, there were approximately 2,065 securities in the Index. The investment grade securities in the Index are listed and traded on U.S. exchanges and are rated BBB or higher by Standard & Poor’s Global Ratings (“S&P”) or Fitch Ratings Ltd. (“Fitch”) or Baa or higher by Moody’s Investors Service, Inc. (“Moody’s”).The Portfolio will normally maintain a dollar-weighted average maturity between 5 and 10 years, which is consistent with that of the Index. The Portfolio will normally maintain an average duration consistent with that of the Index. As of February 28, 2023, the average duration of the Index was 6.1 years.The Portfolio also may invest up to 10% of its assets in exchange-traded funds (“ETFs”) that seek to track the Corporate Bond Index.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Portfolio. There can be no assurance that the Portfolio will achieve its investment objective.The following risks can negatively affect the Portfolio’s performance. The most significant risks as of the date of this Prospectus are presented first, followed by additional principal risks in alphabetical order.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 may decline due to factors that are specifically related to a particular company, as well as 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. Changes in the financial condition of a single issuer can impact a market as a whole.Geopolitical events, including terrorism, tensions, war or other open conflicts between nations, or political or economic dysfunction within some nations that are global economic powers or major producers of oil, 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 important 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 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.The U.S. Federal Reserve (“Fed”) has invested or otherwise made available substantial amounts of money to keep credit flowing through short-term money markets and has signaled that it will continue to adjust its operations as appropriate to support short-term money markets. Amid these efforts, concerns about the markets’ dependence on the Fed’s provision of liquidity have grown. Policy changes by the U.S. government and/or the Fed and political events within the United States may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.A downgrade of the ratings of U.S. government debt obligations, or concerns about the U.S. government’s credit quality in general, could have a substantial negative effect on the U.S. and global economies. High public debt in the United States and other countries creates ongoing systemic and market risks and policymaking uncertainty.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.Index Strategy Risk — The Portfolio employs an index strategy and generally will not modify its index strategy to respond to changes in market trends or the economy, which means that the Portfolio may be particularly susceptible to a general decline in the market segment relating to the relevant index. In addition, although the index strategy attempts to closely track the relevant index, the Portfolio may not invest in all of the securities in the index. Therefore, there can be no assurance that the performance of the index strategy will match that of the relevant index. Because the Portfolio utilizes a representative sampling approach, it may experience greater tracking error than it would if the Portfolio sought to replicate the index.To the extent that the Corporate Bond Index has a significant weighting in a particular sector, the Portfolio will be subject to the risks associated with that sector and may experience greater performance volatility than a portfolio that seeks to track the performance of an index that is more broadly diversified. The Corporate Bond Index typically has a significant weighting in the financial services sector, therefore, the value of the Portfolio’s shares may be particularly vulnerable to factors affecting that sector, such as the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, extensive government regulation and price competition.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.Interest Rate Risk — Changes in interest rates may affect the yield, liquidity and value of investments in income producing or debt securities. Changes in interest rates also may affect the value of other securities. When interest rates rise, the value of the Portfolio’s debt securities generally declines. Conversely, when interest rates decline, the value of the Portfolio’s debt securities generally rises. Typically, the longer the maturity (i.e., the term of a debt security) or duration (i.e., a measure of the sensitivity of a debt security to changes in market interest rates, based on the entire cash flow associated with the security) of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Portfolio’s debt securities to interest rate risk will increase the greater the duration of those securities. A significant or rapid rise in interest rates could result in losses to the Portfolio.Investment Grade Securities Risk — Securities rated in the lower investment grade rating categories (e.g., BBB or Baa) are considered investment grade securities, but are somewhat riskier than higher rated obligations because they are regarded as having only an adequate capacity to pay principal and interest, are considered to lack outstanding investment characteristics, and may possess certain speculative characteristics.ETFs Risk — The Portfolio’s shareholders will indirectly bear fees and expenses paid by the ETFs in which it invests, in addition to the Portfolio’s direct fees and expenses. 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 will be subject to fluctuations in the market values of the ETFs in which it invests. The Portfolio is also subject to the risks associated with the securities or other investments in which the ETFs invest, and the ability of the Portfolio to meet its investment objective will directly depend on the ability of the ETFs to meet their investment objectives. A passively managed (or index-based) ETF’s performance may not match that of the index it seeks to track. An actively managed ETF’s performance will reflect its manager’s ability to make investment decisions that are suited to achieving the ETF’s investment objective. Furthermore, it is possible that an active trading market for an ETF may not develop or be maintained, in which case the liquidity and value of the Portfolio’s investment in the ETF could be substantially and adversely affected. The extent to which the investment performance and risks associated with the Portfolio correlate to those of a particular ETF will depend upon the extent to which the Portfolio’s assets are allocated from time to time for investment in the ETF, which will vary.Liquidity Risk — From time to time, there may be little or no active trading market for a particular investment in which the Portfolio may invest or is invested. In such a market, the value of such an investment and the Portfolio's share price may fall dramatically. Illiquid investments may be difficult or impossible to sell or purchase at an advantageous time or price or in sufficient amounts to achieve the Portfolio's desired level of exposure. To meet redemption requests during periods of illiquidity, the Portfolio may be forced to dispose of investments at unfavorable times or prices and/or under unfavorable conditions, which may result in a loss or may be costly to the Portfolio. Investments that are illiquid or that trade in lower volumes may be more difficult to value. The Portfolio also may not receive its proceeds from the sale of certain investments for an extended period of time. Certain investments that were liquid when purchased may later become illiquid, sometimes abruptly, particularly in times of overall economic distress or adverse investor perception. An inability to sell a portfolio position can adversely affect the Portfolio's value or prevent the Portfolio from being able to take advantage of other investment opportunities. During periods of market stress, an investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Portfolio's ability to limit losses. In addition, a reduction in the ability or willingness of dealers and other institutional investors to make a market in certain securities may result in decreased liquidity in certain markets.New Portfolio Risk — The Portfolio is newly or recently established and has limited operating history. The Portfolio may not be successful in implementing its investment strategy, and there can be no assurance that the Portfolio will grow to or maintain an economically viable size, which could result in the Portfolio being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Until the Portfolio is fully capitalized, it may be unable to pursue its investment objective or execute its principal investment strategies.Non-U.S. Issuer Risk — The Portfolio may invest in U.S.-registered, dollar-denominated bonds of non-U.S. corporations. Investments in bonds of non-U.S. issuers may involve certain risks that are greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs.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.Redemption Risk — The Portfolio may experience periods of heavy redemptions that could cause the Portfolio to sell assets at inopportune times or at a loss or depressed value. Redemption risk is heightened during periods of declining or illiquid markets. Heavy redemptions could hurt the Portfolio's performance.Market developments and other factors, including a general rise in interest rates, have the potential to cause investors to move out of fixed income securities on a large scale, which may increase redemptions from mutual funds that hold large amounts of fixed income securities. The market-making capacity of dealers has been reduced in recent years, in part as a result of structural changes, such as fewer proprietary trading desks at broker-dealers and increased regulatory capital requirements. In addition, significant securities market disruptions related to the coronavirus disease (COVID-19) pandemic have led to dislocation in the market for a variety of fixed income securities (including, without limitation, commercial paper, corporate debt securities, certificates of deposit, asset-backed debt securities and municipal obligations), which has decreased liquidity and sharply reduced returns in certain cases. Increased redemptions from mutual funds that hold large amounts of fixed income securities, coupled with a reduction in the ability or willingness of dealers and other institutional investors to buy or hold fixed income securities, may result in decreased liquidity and increased volatility in the fixed income markets.
