Fees and Expenses of the Fund.This table describes the fees and expenses that you may pay if you buy and hold or redeem shares of the Fund. The accompanying prospectus of the participating insurance company provides information on initial or contingent deferred sales charges, exchange fees or redemption fees for that variable life insurance policy, variable annuity or other investment product. The fees and expenses of those products are not charged by the Fund and are not reflected in this table. Expenses would be higher if those fees were included.

rr_PortfolioTurnoverTextBlock

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the example, affect the Fund's performance.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Principal Risks. The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Fund invests or because of poor investment selection, which could cause the Fund to underperform other funds with similar investment objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.

Asset Allocation Risk. Because the Fund typically invests in a combination of securities, the Fund's ability to achieve its investment objective depends largely upon the portfolio managers' skill in selecting the best mix of investments. There is the risk that the portfolio managers' evaluations and assumptions regarding prospects of the global financial markets may be incorrect and the Fund's performance may be adversely affected by their asset allocation decisions.

Market Risk. The value of the securities in which the Fund invests may be affected by changes in the securities markets. Securities markets may experience significant short-term volatility and may fall sharply at times. Different markets may behave differently from each other and U.S. markets may move in the opposite direction from one or more foreign markets.

Main Risks of Alternative Asset Classes. The Fund's investments in asset classes that the portfolio managers expect to perform differently from its equity and fixed-income investments may be volatile or illiquid, particularly during periods of market instability, and they may not provide the expected returns.

Main Liquidity Risks. Securities that are difficult to value or to sell promptly at an acceptable price are generally referred to as "illiquid" securities. If it is required to sell securities quickly or at a particular time (including sales to meet redemption requests) the Fund could realize a loss on illiquid investments.

Main Risks of Investing in Equity Securities. Stocks and other equity securities fluctuate in price. The value of the Fund's portfolio may be affected by changes in the equity markets generally. Equity markets may experience significant short-term volatility and may fall sharply at times. Different markets may behave differently from each other and U.S. equity markets may move in the opposite direction from one or more foreign markets.

The prices of individual equity securities generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company's securities. These factors may include: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company's sector or industry, or changes in government regulations affecting the company or its industry.

At times, the Fund may emphasize investments in a particular industry or market sector. To the extent that it increases its emphasis on a particular industry or sector, the value of its investments may fluctuate more in response to events (such as changes in economic conditions, government regulations, or the availability of basic resources or supplies) that affect that particular industry or sector more than others.

Main Risks of Small- and Mid-Sized Companies. The stock prices of small- and mid-sized companies may be more volatile and their securities may be more difficult to sell than those of larger companies. They may not have established markets, may have fewer customers and product lines, may have unseasoned management or less management depth and may have more limited access to financial resources. Smaller companies may not pay dividends or provide capital gains for some time, if at all.

Main Risks of Debt Securities. Debt securities may be subject to credit risk, interest rate risk, duration risk, prepayment risk, reinvestment risk, extension risk and event risk. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund's income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer's credit rating, for any reason, can also reduce the market value of the issuer's securities. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and they may be worth less than the amount the Fund paid for them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. When interest rates fall, debt securities may be repaid more quickly than expected and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates fall, the Fund may be required to reinvest the proceeds from a security's sale or redemption at a lower interest rate. This is referred to as "reinvestment risk". When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are at, or near, historic lows. Duration risk is the risk that longer-duration debt securities will be more volatile and more likely to decline in price in a rising interest rate environment than shorter-duration debt securities. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns can cause increased volatility in those debt securities or debt securities markets. Under some circumstances, as was the case during the latter half of 2008 and early 2009, those concerns could cause reduced liquidity in certain debt securities markets. A lack of liquidity or other adverse credit market conditions may hamper the Fund's ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Special Risks of Below-Investment-Grade Securities. Below-investment-grade debt securities (also referred to as "junk" bonds), whether rated or unrated, may be subject to greater price fluctuations than investment-grade securities, increased credit risk and a greater risk that the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell, especially during times of market volatility or decline.

Main Risks of Commodity-Linked Investments. Commodity-linked investments are considered speculative and have substantial risks, including the risk of loss of a significant portion of their principal value. Prices of commodities and commodity-linked investments may fluctuate significantly over short periods due to a variety of factors, including for example agricultural, economic and regulatory developments. These risks may make commodity-linked investments more volatile than other types of investments.

Risks of Mining & Metal Industry Securities. Investments in mining and metal industry companies may be speculative and may be subject to greater price volatility than investments in other types of companies. The special risks of mining and metal industry investments include:

changes in international monetary policies or economic and political conditions can affect the supply of gold and precious metals and consequently the value of mining and metal company investments;
the United States or foreign governments may pass laws or regulations limiting metal investments for strategic or other policy reasons;
the principal supplies of gold are concentrated in only five countries or territories: Australia, Canada, Russia and certain other former Soviet Union countries, South Africa and the United States; and
increased environmental or labor costs may depress the value of mining and metal investments.

Main Risks of Investing in Gold ETFs. An exchange-traded fund that invests in gold bullion ("Gold ETF") is a publicly-traded investment entity that acquires and physically holds gold bullion, the shares of which are intended to reflect the price performance of gold bullion. A Gold ETF will sell gold from time to time to pay expenses, which will reduce the amount of gold represented by each ETF share. Investment in a Gold ETF is subject to the same risks of investing directly in gold bullion, including tax risk. The market value of Gold ETF shares may differ from their net asset value because the supply and demand of Gold ETF shares may be different from the supply and demand for the underlying asset. The Fund will indirectly bear its proportionate share of the management fees associated with Gold ETFs. It is possible that a Gold ETF in which the Fund invests may have to liquidate its holdings at a time when the price of gold is falling.

Main Risks of Investing in Real Estate Markets. The performance of the Fund's investments in real estate securities is closely linked to the performance of the real estate markets. Property values or revenues from real estate investments may fall due to many different factors, including market disruptions, declining rents, negative economic developments that affect businesses and indivuduals, increased operating costs, low market demand or oversupply, obsolescence, competition, uninsured casualty losses, condemnation losses, environmental liabilities, the failure of borrowers to repay loans in a timely manner, changes in prevailing interest rates or rates of inflation, lack of available credit or changes in federal or state taxation policies that affect real estate. The price of a real estate company's securities may also drop due to dividend reductions, lowered credit ratings, poor management, or other factors that generally affect companies. Real estate companies, including REITs and real estate operating companies (REOCs), tend to be small- and mid-cap companies and their shares may be more volatile and less liquid. An industry downturn could adversely impact the Fund's performance.

Smaller Real Estate Company Risks. Smaller companies are typically subject to greater risk of loss than larger companies. They may be more sensitive to changes in a company's earnings expectations and may experience more price volatility. Smaller companies' securities often trade in lower volumes and may be harder to sell at an acceptable price. Buy and sell transactions in a smaller company's stock could impact the stock's price more than it would a larger company's stock. Smaller real estate companies may have limited access to financial and other resources and lack liquidity in a declining market. They may have unseasoned management and may be more sensitive to changes in management or depth of management skill than larger, more established companies.

Main Risks of Investing in REITs. Investment in REITs is closely linked to the performance of the real estate markets. Property values or revenues from real estate investments may fall due to a number of factors, including but not limited to disruptions in real estate markets, increased vacancies or declining rents, increased property taxes and other operating costs, low demand or oversupply, the failure of borrowers to repay loans in a timely manner, changes in tax and regulatory requirements and changes in interest rates or rates of inflation. Mortgage REITs are particularly subject to interest rate risks.

REITs are dependent upon the quality of their management and may not be diversified geographically or by property type. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. REITs generally tend to be small- to mid-cap stocks and are subject to risks of investing in those securities, including limited financial resources and dependency on heavy cash flow. REITs must satisfy certain requirements in order to qualify for favorable tax treatment under applicable tax laws, and a failure to qualify could adversely affect the value of the REIT. By investing in REITs through the Fund, a shareholder will bear expenses of the REITs in addition to expenses of the Fund.

Special Risks of Foreign Real Estate Investments. Because real estate trends are cyclically unique to different countries and world regions, an up or down real estate market in the U.S. may not coincide with the trend in another country. Fluctuations in the relation of a foreign currency to the U.S. dollar could adversely impact cash flow and profits of real estate companies, which in turn could negatively impact the Fund's performance and ability to pay dividends. Securities of foreign real estate companies may have less trading volume, may lack the level of transparency generally present in U.S. companies, and may be more sensitive to volatility. In emerging markets in particular, real estate ownership laws, land rights and tax laws are subject to rapid and unexpected changes as a result of regulatory and political changes. Foreign real estate investments in those countries are more susceptible to the imposition of adverse or confiscatory taxes on foreign properties, currency transfer restrictions, expropriation and difficulty in enforcing obligations.

Main Risks of Master Limited Partnerships. Investments in securities of master limited partnerships ("MLPs") involve risks that differ from investments in common stock, including risks related to common unit holder's limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP's general partner, cash flow risks, dilution risks and risks related to the general partner's right to require unit holders to sell their common units at an undesirable time or price.

MLP common units, like other equity securities, can be affected by macro-economic and other factors affecting the stock market in general, expectations of interest rates, investor sentiment towards an issuer or certain market sector, changes in a particular issuer's financial condition, or poor performance of a particular issuer. Prices of an MLPs common units also can be affected by fundamentals unique to the partnership or company, including earnings power and coverage ratios. A holder of MLP common units typically would not be shielded to the same extent that a shareholder of a corporation would be. In certain circumstances, creditors of an MLP would have the right to seek return of capital distributed to a limited partner, which right would continue after an investor sold its investment in the MLP.

MLP debt securities, including bonds and debentures, have characteristics similar to the fixed income securities of other issuers.

Main Risks of Energy Infrastructure and Energy Related Assets or Activities. Energy infrastructure are subject to risks specific to the energy and energy-related industries, including, but not limited to, fluctuations in commodity prices may impact the volume of energy commodities available for processing and distribution which could affect the profitability of an MLP; slowdowns in new construction and acquisitions can limit growth potential; reduced demand for oil, natural gas and petroleum products could adversely affect MLP revenues and cash flows; depletion of natural gas reserves or other commodities, if not replaced, could impact an MLP's ability to make distributions; changes in the regulatory environment could adversely affect the profitability of MLPs; extreme weather and environmental hazards could impact the value of MLP securities; rising interest rates could result in higher costs of capital and drive investors into other investment opportunities; and threats of attack by terrorists on energy assets could impact the market for MLPs.

Main Risks of Event-Linked Securities. Event-linked securities are fixed income securities for which the return of principal and payment of interest is contingent on the non-occurrence of a trigger event, such as a hurricane, earthquake, or other event that leads to physical or economic loss. If the trigger event occurs prior to maturity, the Fund may lose all or a portion of its principal and additional interest. Event-linked securities may expose the Fund to certain other risks, including issuer default, adverse regulatory or jurisdictional interpretations, liquidity risk and adverse tax consequences.

Main Risks of Foreign Investing. Foreign securities are subject to special risks. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company's operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company's assets, or other political and economic factors. These risks may be greater for investments in developing or emerging market countries.

Special Risks of Developing and Emerging Markets. The economies of developing or emerging market countries may be more dependent on relatively few industries that may be highly vulnerable to local and global changes. The governments of developing and emerging market countries may also be more unstable than the governments of more developed countries. These countries generally have less developed securities markets or exchanges, and less developed legal and accounting systems. Securities may be more difficult to sell at an acceptable price and may be more volatile than securities in countries with more mature markets. The value of developing or emerging market currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company's assets, restrictions on foreign ownership of local companies and restrictions on withdrawing assets from the country. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Foreign Currency Risk. Fluctuations in foreign currency values will result in fluctuations in the U.S. dollar value of securities denominated in that foreign currency. If the U.S. dollar rises in value against a foreign currency, a security denominated in that currency will be worth less in U.S. dollars and if the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency will be worth more in U.S. dollars. The dollar value of foreign investments may also be affected by exchange controls.

The portfolio manager's selection of foreign currency denominated investments may not perform as expected. Currency derivative investments may be particularly volatile and subject to greater risks than other types of foreign-currency denominated investments.

Special Risks of Sovereign Debt. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.

Main Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, require the payment of premiums, can increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counterparty risk and the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful. In addition, under new rules enacted and currently being implemented under U.S. financial reform legislation, certain over-the-counter derivatives are (or soon will be) required to be executed on a regulated market and cleared through a central clearing house counterparty. It is unclear how these regulatory changes will affect counterparty risk, and entering into a derivative transaction with a central clearing house counterparty may entail further risks and costs.

Main Risks of Leverage. Certain derivatives and other investments of the Fund may involve leverage. Leverage may be created when an investment exposes the Fund to a risk of loss that exceeds the amount invested. Certain derivatives and other investments provide the potential for investment gain or loss that may be several times greater than the change in the value of an underlying security, asset, interest rate, index or currency, resulting in the potential for a loss that may be substantially greater than the amount invested.

Some derivatives and other leveraged investments have the potential for unlimited loss, regardless of the size of the initial investment. Because leverage can magnify the effects of changes in the value of the Fund and make the Fund's share price more volatile, a shareholder's investment in the Fund will tend to be more volatile, resulting in larger gains or losses in response to the fluctuating prices of the Fund's investments.

Main Risks of Inflation-Protected Debt Securities. Inflation-indexed bonds, including Treasury Inflation-Protected Securities (TIPS), are fixed income securities whose principal value is periodically adjusted according to an identified rate of inflation. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds with similar maturities. If inflation declines, the principal amount or the interest rate of an inflation-indexed bond will be adjusted downward. This will result in reduced income and may result in a decline in the bond's price which could cause losses for the Fund. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal or interest rate is adjusted for inflation. Inflation-indexed bonds normally will decline in price when real interest rates rise which could cause losses for the fund.

Main Risks Of Investments In The Fund's Wholly-Owned Subsidiary. The Subsidiary is not registered under the Investment Company Act of 1940 and is not subject to its investor protections (except as otherwise noted in this prospectus). As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the Subsidiary is wholly-owned and controlled by the Fund and managed by the Manager and the Sub-Adviser. Therefore, the Fund's ownership and control of the Subsidiary make it unlikely that the Subsidiary would take actions contrary to the interests of the Fund or its shareholders.

Changes in the laws of the Cayman Islands (where the Subsidiary is organized) could prevent the Subsidiary from operating as described in this prospectus and could negatively affect the Fund and its shareholders. For example, the Cayman Islands currently does not impose certain taxes on exempted companies like the Subsidiary, including income and capital gains tax, among others. If Cayman Islands laws were changed to require such entities to pay Cayman Islands taxes, the investment returns of the Fund would likely decrease.

Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and other investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking total return over the long-term from a variety of alternative asset classes and investment strategies through investment in domestic and foreign equity and debt securities, including government and lower-grade debt securities and derivative investments. Those investors should be willing to assume the greater risks of short-term share price fluctuations and the special credit risks that are typical for a fund that invests mainly in lower-grade fixed-income securities and foreign securities. The Fund is not designed for investors needing an assured level of current income. The Fund is not a complete investment program and may not be appropriate for all investors. You should carefully consider your own investment goals and risk tolerance before investing in the Fund.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Risk Lose Money [Text]

rr_RiskLoseMoney

The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Fund invests or because of poor investment selection, which could cause the Fund to underperform other funds with similar investment objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
