Volatility Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Volatility Management Risk.Although the Subadviser attempts to adjust the Portfolio’s overall exposure to volatility, there can be no guarantee that the Subadviser will be successful in managing the Portfolio’s overall level of volatility. The Portfolio may not realize the anticipated benefits from its volatility management strategies or it may realize losses because of the investment techniques employed by the Subadviser to manage volatility, the implementation of those strategies by the Subadviser or the limitations of those strategies in times of extremely low volatility or extremely high volatility. Under certain market conditions, the use of volatility management strategies by the Subadviser may also result in less favorable performance than if such strategies had not been used. For example, if the Portfolio has reduced its overall exposure to equities to avoid losses in certain market environments, the Portfolio may forego some of the returns that can be associated with periods of rising equity values.
Model and Data Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Model and Data Risk.When the quantitative models (“Models”) and information and data (“Data”) used in managing the Portfolio contain an error, are input or designed incorrectly, or prove to be incorrect or incomplete, any investment decisions made in reliance on the Models and Data may not produce the desired results and the Portfolio may realize losses. Models may cause the Portfolio to underperform other investment strategies and may not perform as intended in volatile markets. In addition, any hedging based on faulty Models and Data may prove to be unsuccessful. Furthermore, the success of Models that are predictive in nature is dependent largely on the accuracy and reliability of the supplied historical data. All Models are susceptible to input errors which may cause the resulting information to be incorrect.
Asset Allocation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Asset Allocation Risk.The Portfolio’s ability to achieve its investment objective depends upon BIA’s analysis of various factors and the mix of asset classes that results from such analysis, which may prove incorrect. The particular asset allocation selected for the Portfolio may not perform as well as other asset allocations that could have been selected for the Portfolio. The Portfolio may experience losses or poor relative performance if BIA allocates a significant portion of the Portfolio’s assets to an asset class that does not perform as BIA anticipated, including relative to other asset classes or other subsets of asset classes. The Portfolio may underperform funds that allocate their assets differently than the Portfolio.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk.Derivatives risk is both a direct and indirect risk of investing in the Portfolio. The Portfolio or Underlying Portfolios may invest in derivatives to obtain investment exposure, enhance return or “hedge” or protect its assets from an unfavorable shift in the value or rate of a reference instrument or asset. Derivatives can be highly volatile and can significantly increase the Portfolio’s or an Underlying Portfolio’s exposure to market risk, credit and counterparty risk and other risks. Derivatives may be illiquid and difficult to value and can involve risks in addition to, and potentially greater than, the risks of the underlying reference instrument. Because of their complex nature, some derivatives may not perform as intended. As a result, the Portfolio or an Underlying Portfolio may not realize the anticipated benefits from a derivative it holds or it may realize losses. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivative transactions may create investment leverage, which increases the Portfolio’s or an Underlying Portfolio’s volatility and may require such Portfolio to liquidate portfolio securities when it is not advantageous to do so. Government regulation of derivative instruments may limit or prevent the Portfolio or an Underlying Portfolio from using such instruments as part of its investment strategies, which could adversely affect the Portfolio or Underlying Portfolio.
Forward and Futures Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Forward and Futures Contract Risk.The successful use of forward and futures contracts will depend upon the Subadviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of forward and futures contracts include (i) the imperfect correlation between the change in market value of the instruments held by the Portfolio and the price of the forward or futures contract; (ii) possible lack of a liquid market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) the Subadviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (v) the possibility that the counterparty will default in the performance of its obligations; (vi) if the Portfolio has insufficient cash, it may have to sell securities to meet daily variation margin requirements, and the Portfolio may have to sell securities at a time when it is disadvantageous to do so; (vii) the possibility that the Portfolio may be delayed or prevented from recovering margin or other amounts deposited with a futures commission merchant or clearinghouse; (viii) the possibility that position or trading limits will preclude the Subadviser from taking positions in certain futures contracts on behalf of the Portfolio; and (ix) the risks typically associated with foreign investments to the extent the Portfolio invests in derivatives traded on markets outside the United States.
Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Leveraging Risk.Leveraging risk is a direct risk of investing in the Portfolio. Derivatives and other transactions that give rise to leverage may cause the Portfolio’s performance to be more volatile than if the Portfolio had not been leveraged. Leveraging also may require that the Portfolio liquidate portfolio securities when it is not advantageous to do so to satisfy its obligations. Leveraging may expose the Portfolio to losses in excess of the amounts invested or borrowed. Leverage can create an interest expense that would lower the Portfolio’s overall returns. There can be no guarantee that a leveraging strategy will be successful.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk.Market risk is both a direct and indirect risk of investing in the Portfolio. The Portfolio’s or an Underlying Portfolio’s share price can fall because of, among other things, a decline in the market as a whole, deterioration in the prospects for a particular industry or company, changes in general economic conditions, such as prevailing interest rates or investor sentiment, or other factors including terrorism, war, natural disasters and the spread of infectious illness including epidemics or pandemics. In addition, unexpected political, regulatory, trade and diplomatic events within the United States and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Significant disruptions to the financial markets could adversely affect the liquidity and volatility of securities held by the Portfolio or an Underlying Portfolio.
Forward Commitment When Issued and Delayed Delivery Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Forward Commitment, When-Issued and Delayed Delivery Securities Risk.Forward commitment, when-issued and delayed delivery securities risk is both a direct and indirect risk of investing in the Portfolio. Investments in forward commitments and when-issued and delayed delivery securities are subject to the risk that the value or yield of the securities the Portfolio or Underlying Portfolio is obligated to purchase will decline below the agreed upon purchase price or expected yield before the securities are actually issued or delivered. These investments may create a form of investment leverage, which may increase the Portfolio’s or Underlying Portfolio’s volatility and may require the Portfolio or Underlying Portfolio to liquidate portfolio securities when it is not advantageous to do so.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk.Interest rate risk is both a direct and indirect risk of investing in the Portfolio. The value of the Portfolio’s or an Underlying Portfolio’s investments in fixed income securities may decline when prevailing interest rates rise or increase when interest rates fall. The longer a security’s maturity or duration, the greater its value will change in response to changes in interest rates. The Portfolio’s fixed-income portion will normally have a greater maturity or duration than will its benchmark. The interest earned on the Portfolio’s or an Underlying Portfolio’s investments in fixed income securities may decline when prevailing interest rates fall. During periods of very low or negative interest rates, the Portfolio or an Underlying Portfolio may be unable to maintain positive returns or pay dividends to Portfolio or Underlying Portfolio shareholders, respectively. Additionally, under certain market conditions in which interest rates are low or negative, the Portfolio or an Underlying Portfolio may have a very low, or even negative yield. A low or negative yield would cause the Portfolio or an Underlying Portfolio to lose money and the net asset value of the Portfolio’s or the Underlying Portfolio’s shares to decline in certain conditions and over certain time periods. Changes in prevailing interest rates, particularly sudden changes, may also increase the level of volatility in fixed income and other markets, increase redemptions in the Portfolio’s or an Underlying Portfolio’s shares and reduce the liquidity of the Portfolio’s or an Underlying Portfolio’s debt securities and other income-producing holdings. Changes in interest rate levels are caused by a variety of factors, such as central bank monetary policies, inflation rates, and general economic and market conditions.
Credit and Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit and Counterparty Risk.Credit and counterparty risk is both a direct and indirect risk of investing in the Portfolio. The value of the Portfolio’s or an Underlying Portfolio’s investments may be adversely affected if a security’s credit rating is downgraded or an issuer of an investment held by the Portfolio or an Underlying Portfolio fails to pay an obligation on a timely basis, otherwise defaults or is perceived by other investors to be less creditworthy. If a counterparty to a derivatives or other transaction with the Portfolio or an Underlying Portfolio files for bankruptcy, becomes insolvent, or otherwise becomes unable or unwilling to honor its obligation to the Portfolio or an Underlying Portfolio, the Portfolio or an Underlying Portfolio may experience significant losses or delays in realizing income on or recovering collateral and may lose all or a part of the income from the transaction.
Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Investment Risk.Foreign investment risk is both a direct and indirect risk of investing in the Portfolio. Investments in foreign securities, whether direct or indirect, tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, economic and other developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates. To the extent the Portfolio invests in foreign sovereign debt securities, it is subject to additional risks.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Emerging Markets Risk.Emerging Markets Risk is both a direct and indirect risk of investing in the Portfolio. In addition to all of the risks of investing in foreign developed markets, emerging market securities involve risks attendant to less mature and stable governments and economies, lower trading volume, trading suspension, security price volatility, proceeds repatriation restrictions, withholding and other taxes, some of which may be confiscatory, inflation, deflation, currency devaluation and adverse government regulations of industries or markets. As a result of these risks, the prices of emerging market securities tend to be more volatile than the securities of issuers located in developed markets.
Short Sale and Short Position Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Short Sale and Short Position Risk.Short Sale and Short Position Risk is both a direct and indirect risk of investing in the Portfolio. The Portfolio or an Underlying Portfolio will incur a loss from a short sale or short position if the value of the security sold short or the reference instrument, in the case of a short position, increases after the time the Portfolio or Underlying Portfolio entered into the short sale or short position. In addition, when the Portfolio engages in short sales, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Portfolio may have to buy the securities sold short at an unfavorable price. Engaging in a short sale or short position may cause the Portfolio to lose more money than the actual cost of the short sale or short position and the Portfolio’s potential losses may be unlimited if the Portfolio or Underlying Portfolio does not own the security sold short or the reference instrument and it is unable to close out of the short sale or short position. Any gain from a short sale or short position will be offset in whole or in part by the transaction costs associated with the short sale or short position. Short sales and short positions generally involve a form of leverage, which can exaggerate the Portfolio’s or an Underlying Portfolio’s losses.
Mortgage Backed and Asset Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mortgage-Backed and Asset-Backed Securities Risk.Mortgage-backed and asset-backed securities risk is both a direct and indirect risk of investing in the Portfolio. The value of investments in mortgage-backed and asset-backed securities is subject to interest rate risk and credit and counterparty risk. These securities are also subject to the risk that issuers will prepay the principal more quickly or more slowly than expected, which could cause the Portfolio or an Underlying Portfolio to invest the proceeds in less attractive investments or increase the volatility of their prices. To the extent mortgage-backed and asset-backed securities held by the Portfolio or an Underlying Portfolio are backed by lower rated securities, such as sub-prime obligations, or are subordinated to other interests in the same mortgage or asset pool, the likelihood of the Portfolio or an Underlying Portfolio receiving payments of principal or interest may be substantially limited.
TIPS and Inflation Linked Bonds Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] TIPS and Inflation-Linked Bonds Risk.TIPS and Inflation-Linked Bonds Risk is both a direct and indirect risk of investing in the Portfolio. The value of inflation-protected securities generally fluctuates in response to changes in real interest rates, which are in turn tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates would decline, leading to an increase in the value of inflation-protected securities. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates would rise, leading to a decrease in the value of inflation-protected securities. When real interest rates are rising faster than nominal interest rates, inflation-indexed bonds, including Treasury Inflation Protected Securities, may experience greater losses than other fixed income securities with similar durations. The inflation-protected securities markets are generally much smaller and less liquid than the markets for nominal bonds from the same issuers and as such can suffer losses during times of economic stress or illiquidity.
Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Portfolio Turnover Risk.Portfolio Turnover Risk is both a direct and indirect risk of investing in the Portfolio. The investment techniques and strategies utilized by the Portfolio and Underlying Portfolios might result in a high degree of portfolio turnover. High portfolio turnover rates will increase the Portfolio’s and Underlying Portfolios’ transaction costs, which can adversely affect the Portfolio’s performance and the returns on the Portfolio’s investments in those Underlying Portfolios. Other direct risks of investing in the Portfolio also include:
Underlying Portfolio Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Underlying Portfolio Risk.The investment performance of a Portfolio that invests a significant percentage of its assets in Underlying Portfolios may be adversely affected if the Underlying Portfolios are unable to meet their investment objectives or the Portfolio allocates a significant portion of its assets to an Underlying Portfolio that performs poorly, including relative to other Underlying Portfolios. Any Underlying Portfolio may have multiple asset class exposures and such exposures may change over time. In addition, the Portfolio bears its pro-rata portion of the operating expenses of the Underlying Portfolios in which it invests. Indirect risks of investing in the Portfolio (direct risks of investing in the Underlying Portfolios) include:
Market Capitalization Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Capitalization Risk.Investing primarily in issuers in one market capitalization category (large, medium or small) carries the risk that due to current market conditions that category will be out of favor with investors. Larger, more established companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies. Stocks of medium and small capitalization companies may be more volatile than those of larger companies due to, among other things, narrower product lines, more limited financial resources and fewer experienced managers. In addition, there is typically less publicly available information about small capitalization companies, and their stocks may have a more limited trading market than stocks of larger companies.
Investment Style Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Investment Style Risk.Different investment styles such as growth or value tend to shift in and out of favor, depending on market and economic conditions as well as investor sentiment. An Underlying Portfolio may outperform or underperform other funds that employ a different investment style.
High Yield Debt Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] High Yield Debt Security Risk.High yield debt securities, or “junk” bonds, may be more susceptible to market risk and credit and counterparty risk than investment grade debt securities because issuers of high yield debt securities are less secure financially and their securities are more sensitive to downturns in the economy. In addition, the secondary market for high yield debt securities may not be as liquid as that for higher rated debt securities. High-yield debt securities range from those for which the prospect for repayment of principal and interest is predominantly speculative to those which are currently in default on principal or interest payments or whose issuers are in bankruptcy.
Loan Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Loan Investment Risk.Investments in loans expose an Underlying Portfolio to interest rate risk and the credit and counterparty risk of the underlying borrowers of those loans. No active trading market may exist for certain loans. Moreover, adverse market conditions may impair the liquidity of some actively traded loans. An Underlying Portfolio may have difficulty valuing and selling loans that are illiquid or are less actively traded. Loans are also subject to the risk that borrowers will prepay the principal more quickly than expected, which could cause an Underlying Portfolio to reinvest the repaid principal in investments with lower yields, thereby exposing an Underlying Portfolio to a lower rate of return. There may be a limited amount of public information about the loans in which an Underlying Portfolio invests. Purchases and sales of loans are generally subject to contractual restrictions that may impede an Underlying Portfolio’s ability to buy or sell loans and may negatively affect the transaction price. Loan transactions may take longer than seven days to settle, and an Underlying Portfolio may hold cash, sell investments, or temporarily borrow from banks or other lenders in order to meet short-term liquidity needs. An Underlying Portfolio may not be entitled to rely on the anti-fraud protections of the federal securities laws with respect to any loans it owns in the event of fraud or misrepresentation by a borrower. An Underlying Portfolio’s purchase and sale of loans may involve the risk of market manipulation by a borrower. Any investments in below investment grade loans and other debt securities expose a portfolio to greater market risk and credit and counterparty risk than a portfolio that invests only in investment grade loans and debt securities. Lower rated securities also may be subject to greater price volatility than higher rated investments.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You could lose money by investing in the Portfolio.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Portfolio through a Contract is not a deposit or obligation of, or guaranteed by, any bank, and is not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. Government.
