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. These costs, which are not reflected in the annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 129% of the average value of its portfolio.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

The following Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. Sales charges and fees for the variable life insurance policy, variable annuity or other investment product offered by participating insurance companies are not charged by the Fund and are not reflected in the Example. Expenses would be higher if those fees were included. The Example assumes that you invest $10,000 in a class of shares of the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Any applicable fee waivers and/or expense reimbursements are reflected in the below examples for the period during which such fee waivers and/or expense reimbursements are in effect. Although your actual costs may be higher or lower, based on these assumptions your expenses would be as follows, whether or not you redeemed your shares:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing in alternative (or non-traditional) asset classes and investment strategies, including but not limited to the following:

Fundamental and quantitatively driven alpha strategies, such as global macro (investment across broad asset and/or sector classes), equity long/short, currency and volatility arbitrage strategies

Real assets, such as commodities, gold and other precious metals and minerals, real estate and master limited partnerships (MLPs)

Income alternatives, such as event-linked securities and loans

The Fund may invest in some or all of the asset classes and strategies listed above, but under normal market conditions will not invest more than 50% of its total assets in any single asset class. The Fund’s sub-adviser, OppenheimerFunds, Inc. (“OFI” or the “Sub-Adviser”), will monitor the markets and allocate assets among asset classes and strategies based on changing market or economic conditions or investment opportunities. The Fund may change its emphasis on an asset class or strategy based on the Sub-Adviser’s and the Fund’s Sub-Sub-Advisers’ evaluation of those market and economic factors and investment opportunities. In determining how much of the Fund’s assets to invest in a particular asset class or strategy, the Sub-Adviser looks for opportunities across various asset classes and strategies and attempts to allocate the Fund’s assets in a manner that seeks to generally diversify the portfolio across those asset classes and strategies. In pursuing its investment objective, the Fund has the flexibility to utilize a variety of investment strategies and techniques to select investments, and the list of asset classes and strategies shown above that the Fund may invest in is not exhaustive. In response to changing market or economic conditions or investment opportunities, the Sub-Adviser may change any or all of the Fund’s asset classes and strategies, including changing to asset classes and strategies not listed above, or may change the Fund’s asset allocations, including making no allocation at all to an asset class or strategy. The Sub-Adviser may make such changes at any time without prior approval from or notice to shareholders.

Under normal market conditions, the Fund will invest a substantial portion of its assets in a number of different countries throughout the world, including the United States. The Fund is managed to be “benchmark agnostic” in an attempt to provide positive absolute returns while limiting volatility; however, when compared to its current index (the ICE Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index) the Fund will normally experience higher volatility than the index.

The Fund may invest in all types of equity securities, including common stock, preferred stock, convertible securities, rights and warrants, and other securities or instruments whose prices are linked to the value of common stock. The Fund may also invest in debt securities of any kind and of varying duration and maturities, including but not limited to, securities that pay a fixed or fluctuating rate of interest, securities convertible into equity securities, securities issued or guaranteed by the U.S. federal and state governments or by their agencies and instrumentalities, securities issued or guaranteed by foreign governments, international agencies or supra-national entities, securities issued or guaranteed by domestic or foreign private issuers, event-linked securities (including “catastrophe” bonds and other insurance-linked securities), senior loans, asset- and mortgage-backed securities, and debt securities whose returns are linked to the performance of a particular market benchmark or strategy (such as exchange-traded notes). The Fund can invest without limit in investment-grade and below investment-grade, high-yield debt securities (commonly referred to as “junk bonds”). “Investment-grade” debt securities are rated in one of the top four rating categories by a nationally recognized statistical rating organization such as Moody’s Investors Service or S&P Global Ratings. The Fund may also invest in unrated securities, in which case the Sub-Adviser may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Sub-Adviser’s credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization.

There is no maximum or minimum amount for investments in either equity or fixed-income securities, except as otherwise indicated in this prospectus or the Fund’s statement of additional information. There are generally no restrictions on where the Fund may invest geographically or on the amount of the Fund’s assets that can be invested in either U.S. or foreign securities, including real estate securities and securities of issuers in developing and emerging markets. The Fund does not limit its investments to issuers in a particular market capitalization range and at times may invest a substantial portion of its assets in one or more particular market capitalization ranges. The Fund’s investment in MLPs is limited to no more than 25% of its total assets.

The Fund can take long positions in investments that are believed to be undervalued and short positions in investments that are believed to be overvalued or which are established for hedging purposes, including long and short positions in equities and equity-sensitive convertibles, fixed income securities, and derivatives or other types of securities. The Fund’s overall long or short positioning can vary based on market and economic conditions, and the Fund may take both long and short positions simultaneously. The Fund can seek to take advantage of arbitrage opportunities in equity and fixed income, commodity, and currency prices and market volatility.

The Fund may invest in the securities of other investment companies, subject to any limits imposed by the Investment Company Act of 1940 Act, as amended, including other entities sponsored and/or advised by the Fund’s investment advisor, OFI Global or an affiliate. The Fund may use derivatives to seek income or capital gain, to hedge against the risks of other investments, or as a substitute for direct investment in a particular asset class. Structured notes, options, futures, forward contracts, and swaps are some of the types of derivatives the Fund can use.

In times of adverse or unstable market or economic conditions, such as reduced market liquidity or increased volatility, the Fund may hold a portion of its assets in cash, money market securities or other similar, liquid investments, including in shares of money market mutual funds in the Oppenheimer family of funds. This may also include shares of funds that provide exposure to inflation-protected debt securities and short-term investment-grade debt securities. This will generally occur at times when there is an inability to immediately invest funds received from purchases of Fund shares or from redemptions of other investments or to maintain liquidity.

The Fund has established a Cayman Islands exempted company that is wholly-owned and controlled by the Fund (the “Subsidiary”). The Fund may invest up to 25% of its total assets in the Subsidiary. The Subsidiary invests primarily in commodity-linked derivatives (including commodity futures, financial futures, options and swap contracts) and exchange-traded funds related to gold or other special minerals (“Gold ETFs”). The Subsidiary may also invest in certain fixed-income securities and other investments that may serve as margin or collateral for its derivatives positions. Investments in the Subsidiary are intended to provide the Fund with exposure to commodities market returns within the limitations of the federal tax requirements that apply to the Fund. The Fund applies its investment restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary. The Fund’s investment in the Subsidiary may vary based on the portfolio managers’ use of different types of commodity-linked derivatives, fixed-income securities, Gold ETFs, and other investments. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments described in this prospectus, the Fund may be considered to be investing indirectly in those investments through its Subsidiary. Therefore, references in this prospectus to investments by the Fund also may be deemed to include the Fund’s indirect investments through the Subsidiary.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The price of the Fund’s shares can go up and down substantially. The value of the Fund’s investments may fall due to adverse 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 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 selecting the best mix of investments. There is the risk that the portfolio manager’s evaluations and assumptions regarding market conditions may be incorrect. During periods of rapidly rising stock prices, the Fund might not achieve growth in its share prices to the same degree as funds focusing only on stocks. The Fund’s investments in stocks may make it more difficult to preserve principal during periods of stock market volatility. The Fund’s use of a particular investment style might not be successful when that style is out of favor and the Fund’s performance may be adversely affected by the asset allocation decisions.

Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: 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. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Risks of Alternative Investment Strategies. The Fund utilizes alternative investment strategies, which are strategies that the portfolio managers expect to result in investment performance that does not correlate with the performance of traditional asset classes, such as equity and fixed-income investments. The Fund also seeks to utilize a diverse mix of alternative investment strategies, in the hope that individual strategies yield low performance correlation to other alternative investment strategies used by the Fund. However, alternative investments may be more volatile or illiquid, particularly during periods of market instability, and the Fund cannot guarantee that diverse alternative investment strategies will yield uncorrelated performance under all market conditions. In addition, the particular mix of alternative investments in the Fund’s portfolio may not be sufficiently diversified. The Fund is subject to the risk that its alternative investments may undergo a correlation shift, resulting in returns that are correlated with the broader market and/or with the Fund’s other alternative investments.

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.

Risks of Other Equity Securities. Most convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

Risks of Small- and Mid-Cap Companies. Small-cap companies may be either established or newer companies, including “unseasoned” companies that have typically been in operation for less than three years. Mid-cap companies are generally companies that have completed their initial start-up cycle, and in many cases have established markets and developed seasoned market teams. While smaller companies might offer greater opportunities for gain than larger companies, they also may involve greater risk of loss. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Small- and mid-cap companies’ securities may trade in lower volumes and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Small- and mid-cap companies may not have established markets for their products or services and may have fewer customers and product lines. They may have more limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Small- and mid-cap companies may have unseasoned management or less depth in management skill than larger, more established companies. They may be more reliant on the efforts of particular members of their management team and management changes may pose a greater risk to the success of the business. It may take a substantial period of time before the Fund realizes a gain on an investment in a small- or mid-cap company, if it realizes any gain at all.

Risks of Investing in Debt Securities. Debt securities may be subject to interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk, prepayment risk and event risk. 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 therefore, those debt securities may be worth less than the amount the Fund paid for them or valued them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. 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. “Credit spread” is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause prepayments on a debt security to occur at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value. Reinvestment risk is the risk that 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. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. 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. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity may decline unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books and could experience a loss. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices, particularly for lower-rated and unrated securities. An unexpected increase in redemptions by Fund shareholders (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by general market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. As of the date of this prospectus, interest rates in the U.S. are near historically low levels, increasing the exposure of bond investors to the risks associated with rising interest rates.

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 may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns may cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all). 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.

Risks of Below-Investment-Grade Securities. As compared to investment-grade debt securities, below-investment-grade debt securities (also referred to as “junk” bonds), whether rated or unrated, may be subject to greater price fluctuations and increased credit risk, as the issuer might not be able to pay interest and principal when due, especially during times of weakening economic conditions or rising interest rates. Credit rating downgrades of a single issuer or related similar issuers whose securities the Fund holds in significant amounts could substantially and unexpectedly increase the Fund’s exposure to below-investment-grade securities and the risks associated with them, especially liquidity and default risk. The market for below-investment-grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline.

Risks of Event-Linked Securities. Event-linked securities (including “catastrophe” bonds and other insurance-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 catastrophe or series of catastrophe events that leads to physical or economic loss(es). 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.

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.

Risks of Exchange-Traded Notes (ETNs). ETNs are senior, unsecured, unsubordinated debt securities traded on an exchange (e.g., the NYSE) whose returns are linked to the performance of a particular market index or strategy, minus applicable fees. ETNs are subject to credit risk, and the value of an ETN may drop due to a downgrade in the issuer’s credit rating. An ETN may lose all or a portion of its value if the issuer fails. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in applicable interest rates, and economic, legal, political or geographic events that affect the underlying assets on which the index is based. The Fund may invest substantially in ETNs that are subject to the risks associated with industry or sector concentration. When the Fund invests in an ETN it will bear its proportionate share of the fees and expenses borne by the ETN, which will reduce the return realized at maturity or upon redemption. The Fund’s decision to sell ETN holdings may be limited by the availability of a secondary market and it may not be able to liquidate ETN holdings at the desired time or price.

The Fund may invest in ETNs for which an affiliate of the Manager provides certain index selection and marketing services. As a result, an affiliate of the Manager may be paid service fees that are indirectly incurred by the Fund and its shareholders (in addition to Fund expenses). The Manager will voluntarily waive a portion of its management fee to the extent that the Fund’s share of service fees paid to affiliates of the Manager are attributable to investment in such an ETN.

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. Commodity-linked investments entail the risk that the Fund might not qualify as a “regulated investment company” under the Internal Revenue Code and its income may become subject to income taxes, reducing returns to shareholders.

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, the governments of which may pass laws or regulations limiting metal investments for strategic or other policy reasons; and

increased environmental or labor costs may depress the value of mining and metal investments.

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.

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 individuals, 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.

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.

          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.

Risks of Derivative Investments. Derivatives may involve significant risks. Derivatives may be more volatile than other types of investments, may require the payment of premiums, may 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 financial reform legislation, certain over-the-counter derivatives are (or soon will be) required to be executed on a regulated market and/or cleared through a clearinghouse. It is unclear how these regulatory changes will affect counterparty risk, and entering into a derivative transaction with a clearinghouse may entail further risks and costs.

Risks of Hedging. The Fund may engage in “hedging” strategies, including short sales, futures and other derivatives in an effort to protect assets from losses due to declines in the value of the Fund’s portfolio. There are risks in the use of these investment and trading strategies. There can be no assurance that the hedging strategies used will be successful in avoiding losses, and hedged positions may perform less favorably in generally rising markets than unhedged positions. If the Fund uses a hedging strategy at the wrong time or judges market conditions incorrectly, the strategy could reduce the Fund’s return. In some cases, derivatives or other investments may be unavailable, or the investment adviser may choose not to use them under market conditions when their use, in hindsight, may be determined to have been beneficial to the Fund. No assurance can be given that the investment adviser will employ hedging strategies with respect to all or any portion of the Fund’s assets.

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.

Risks of Master Limited Partnerships. Investments in securities of master limited partnerships (“MLPs”) are subject to all the risks of investments in common stock, in addition to risks related to the following: a common unit holder’s limited control and limited rights to vote on matters affecting the MLP; potential conflicts of interest between the MLP and the MLP’s general partner; cash flow; dilution; and the general partner’s right to require unit holders to sell their common units at an undesirable time or price. MLP common unit holders may not elect the general partner or its directors and have limited ability to remove an MLP’s general partner. MLPs may issue additional common units without unit holder approval, which could dilute the ownership interests of investors holding MLP common units. 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 unfavorable or unanticipated poor performance of a particular issuer. Prices of common units of individual MLPs, like prices of other equity securities, 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 would continue after an investor sold its investment in the MLP. The value of an MLP security may decline for reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s products or services. Due to the heavy state and federal regulations that an MLP’s assets may be subject to, an MLP’s profitability could be adversely impacted by changes in the regulatory environment.

Generally, the securities markets may move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors. The market value of a security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. A security’s market value also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

MLP Tax Risk. MLPs are generally treated as partnerships for U.S. federal income tax purposes. MLPs generally do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses regardless of whether it receives a cash distribution from the MLP. A change in current tax law, or a change in the underlying business mix of a given MLP, could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which could result in the MLP being required to pay federal income tax (as well as state and local income taxes) on its taxable income. This could have the effect of reducing the amount of cash available for distribution by the MLP, resulting in a reduction of the value of the Fund’s investment in the MLP and lower income to the Fund. Changes in the laws, regulations or related interpretations relating to the Fund’s investments in MLPs could increase the Fund’s expenses, reduce its cash distributions, negatively impact the value of an investment in an MLP, or otherwise impact the Fund’s ability to implement its investment strategy.

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

Risks of Energy Infrastructure and Energy-Related Assets or Activities. Energy infrastructure MLPs 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 transported, processed, stored or distributed; reduced volumes of natural gas or other energy commodities available for transporting, processing, storing or distributing may 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, particularly for a sustained period of time, 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.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. 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 investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. 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. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

          Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ 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, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

          Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

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.

Risks of Long/Short Holdings. Under certain conditions, even if the value of the Fund’s long positions are rising, this could be offset by declining values of the Fund’s short positions. Conversely, it is possible that rising values of the Fund’s short positions could be offset by declining values of the Fund’s long positions. In either scenario the Fund may experience losses. In a market where the value of both the Fund’s long and short positions are declining, the Fund may experience substantial losses.

Risks of Short Sales. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases between the date of the short sale and the date on which the Fund closes the short position. A short sale of a security creates the risk of an unlimited loss, since the price of the security sold short could theoretically increase without limit. Purchasing securities previously sold short to close out a short position can itself cause the price of the securities to rise further, thereby increasing the loss. Further, there is no assurance that a security the Fund needs to buy to cover a short position will be available for purchase at a reasonable price. Short sales may cause a higher portfolio turnover rate and increase the Fund’s brokerage and other transaction expenses. Short selling is considered a speculative investment practice.

Risks of Arbitrage. Arbitrage risk is the risk that securities purchased pursuant to a strategy intended to take advantage of a perceived relationship between the value of two or more securities may not perform as expected.

Risks of Senior Loans and Other Loans. The Fund may invest in loans, and in particular, in floating rate loans (sometimes referred to as “adjustable rate loans”) that hold (or in the judgment of the investment adviser, hold) a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of (or at least as high as) other obligations of a borrower in the event of liquidation. These investments are referred to as “Senior Loans.” Loans may be collateralized or uncollateralized. They typically pay interest at rates that are reset periodically based on a reference benchmark that reflects current interest rates, plus a margin or premium. In addition to the risks typically associated with debt securities, such as credit and interest rate risk, senior loans are also subject to the risk that a court could subordinate a senior loan, which typically holds a senior position in the capital structure of a borrower, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Loans usually have mandatory and optional prepayment provisions. If a borrower prepays a loan, the Fund will have to reinvest the proceeds in other loans or financial assets that may pay lower rates of return.

Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lenders’ security interest or their enforcement of their security under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. The Fund’s access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized loan may not be fully collateralized and can decline significantly in value.

Loan investments are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. These obligations are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy.

Due to restrictions on transfers in loan agreements and the nature of the private syndication of loans including, for example, the lack of publicly-available information, some loans are not as easily purchased or sold as publicly-traded securities. Some loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when it wants to. The market price of investments in floating rate loans are expected to be less affected by changes in interest rates than fixed-rate investments because floating rate loans pay a floating rate of interest that will fluctuate as market interests rates do and therefore should more closely track market movements in interest rates.

Compared to securities and to certain other types of financial assets, purchases and sales of loans take relatively longer to settle. This extended settlement process can (i) increase the counterparty credit risk borne by the Fund; (ii) leave the Fund unable to timely vote, or otherwise act with respect to, loans it has agreed to purchase; (iii) delay the Fund from realizing the proceeds of a sale of a loan; (iv) inhibit the Fund’s ability to re-sell a loan that it has agreed to purchase if conditions change (leaving the Fund more exposed to price fluctuations); (v) prevent the Fund from timely collecting principal and interest payments; and (vi) expose the Fund to adverse tax or regulatory consequences.

To the extent the extended loan settlement process gives rise to short-term liquidity needs, such as the need to satisfy redemption requests, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders. If the Fund undertakes such measures, the Fund’s ability to pay redemption proceeds in a timely manner may be adversely affected, as well as the Fund’s performance.

If the Fund invests in a loan via a participation, the Fund will be exposed to the ongoing counterparty risk of the entity providing exposure to the loan (and, in certain circumstances, such entity’s credit risk), in addition to the exposure the Fund has to the creditworthiness of the borrower.

In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower or an arranger, lenders will not have the protection of the anti-fraud provisions of the federal securities laws, as would be the case for bonds or stocks. Instead, in such cases, lenders generally rely on the contractual provisions in the loan agreement itself, and common-law fraud protections under applicable state law.

Risks of Mortgage-Related Securities. The Fund can buy interests in pools of residential or commercial mortgages in the form of “pass-through” mortgage securities. They may be issued or guaranteed by the U.S. government, or its agencies and instrumentalities, or by private issuers. The prices and yields of mortgage-related securities are determined, in part, by assumptions about the rate of payments of the underlying mortgages and are also subject to interest rate risk, and the market for mortgage-backed securities may be volatile at times and may be less liquid than the markets for other types of securities. Mortgage-related securities issued by private issuers are not U.S. government securities, and are subject to greater credit risks than mortgage-related securities that are U.S. government securities.

Risks of Investments in Other Investment Companies. As an investor in another investment company, the Fund would be subject to the risks of that investment company’s portfolio. Investing in another investment company may also involve paying a premium above the value of that investment company’s portfolio securities and is subject to a ratable share of that investment company’s expenses, including its advisory and administration expenses. The Fund does not intend to invest in other investment companies unless it is believed that the potential benefits of the investment justify the payment of any premiums, expenses or sales charges. The Investment Company Act of 1940 also imposes limitations on mutual funds’ investments in other investment companies.

The Fund may also invest in exchange-traded funds (ETFs), which are subject to all the risks of investing in investment companies as described above. Because ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, shares of ETFs potentially may trade at a discount or a premium to their net asset value. Investments in ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

Risks of Money Market Instruments. The Fund may invest in money market instruments. Money market instruments are short-term, US dollar-denominated debt instruments issued or guaranteed by domestic and foreign corporations and financial institutions, the U.S. government, its agencies and instrumentalities and other entities. Money market instruments include certificates of deposit, commercial paper, repurchase agreements, treasury bills, certain asset-backed securities and other short term debt obligations that have a final maturity, as defined under rules under the Investment Company Act of 1940, of 397 days or less. They may have fixed, variable or floating interest rates. Money market instruments are subject to certain risks, including the risk that an issuer of an obligation that the Fund holds might have its credit rating downgraded or might default on its obligations, or that interest rates might rise sharply, causing the value of the Fund’s investments to fall.

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. In addition, changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information and could adversely affect the Fund. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the performance of the Fund and/or the Subsidiary. 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 below-investment grade debt securities and derivative investments. Those investors should be willing to assume the risks of short-term share price fluctuations, including the volatility that can be associated with alternative asset classes, as well as the special credit risks that are typical for a fund that invests in below-investment grade debt securities and special risks of investing in 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.
