Summary Prospectus by Investment Company - Form 497K

•

Asset-based securities risk - Asset-based securities are typically fixed-income securities whose value is related to the market price of certain commodities, interests, and other items, such as precious metals, as well as other assets, such as credit card receivables. Although the market price of these securities is expected to follow the market price of the related assets, there may not be perfect correlation. There are special risks associated with certain types of assets that will also affect the value of asset-based securities related to those assets. For an example of such special risks, please refer to "Precious metals related securities risk."

•

Collateralized debt obligations risk - Collateralized debt obligations (CDOs) are subject to credit, interest rate, valuation, prepayment and extension risks. In addition, CDOs carry additional risks, including but not limited to: (i) the possibility that distributions from the collateral will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) the Fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment returns achieved by the Fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) risk of a forced "fire sale" liquidation due to technical defaults such as coverage test failures; and (viii) the CDO's manager may perform poorly.

•

Counterparty risk - Transactions involving a counterparty are subject to the credit risk of the counterparty. A fund that enters into contracts with counterparties, such as repurchase or reverse repurchase agreements or derivatives contracts, or that lends its securities, runs the risk that the counterparty will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. If a counterparty fails to meet its contractual obligations, files for bankruptcy, or otherwise experiences a business interruption, the Fund could suffer losses, including monetary losses, miss investment opportunities or be forced to hold investments it would prefer to sell. Counterparty risk is heightened during unusually adverse market conditions.

•

Credit risk - Credit risk is the actual or perceived risk that the issuer of a bond, borrower, guarantor, counterparty, or other entity responsible for payment will not pay interest and principal payments when due. The price of a debt instrument can decline in response to changes in the financial condition of the issuer, borrower, guarantor, counterparty, or other entity responsible for payment. The Fund could lose money if the issuer or guarantor of a fixed-income security, or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations.

•

Derivatives risk - Investments in derivatives, which are financial instruments whose value depends on, or is derived from, the value of underlying assets, reference rates, or indices, can be highly volatile and may be subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. Derivatives also are subject to leverage risk, liquidity risk, interest rate risk, market risk, counterparty risk, and credit risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, interest rate or index. Gains or losses from derivatives can be substantially greater than the derivatives' original cost.

•

Extension risk - When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, which may cause the value of those securities to fall. Rising interest rates tend to extend the duration of securities, making them more sensitive to changes in interest rates. The value of longer-term securities generally changes more in response to changes in interest rates than shorter-term securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.

•

Financial services risk - An investment in issuers in the financial services sector may be adversely affected by, among other things: (i) changes in the regulatory framework or interest rates that may negatively affect financial service businesses; (ii) exposure of a financial institution to a non-diversified or concentrated loan portfolio; (iii) exposure to financial leverage and/or investments or agreements which, under certain circumstances, may lead to losses (e.g., sub-prime loans); and (iv) the risk that a market shock or other unexpected market, economic, political, regulatory, public health or other event might lead to a sudden decline in the values of most or all companies in the financial services sector.

•

Fixed-income risk - The price of fixed-income securities responds to economic developments, particularly interest rate changes, as well as to perceptions about the credit risk of individual issuers. Rising interest rates generally will cause the price of bonds and other fixed-income debt securities to fall. Falling interest rates may cause an issuer to redeem, call or refinance a security before its stated maturity, which may result in the Fund having to reinvest the proceeds in lower yielding securities. Bonds and other fixed-income debt securities are subject to credit risk, which is the possibility that the credit strength of an issuer will weaken and/or an issuer of a fixed-income security will fail to make timely payments of principal or interest and the security will go into default.

•

High-yield bonds, lower-rated bonds, and unrated securities risk - High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as "junk bonds," and are considered below "investment-grade" by national ratings agencies. Junk bonds are subject to the increased risk of an issuer's inability to meet principal and interest payment obligations. As a result, an investment in junk bonds is considered speculative. High-yield bonds may be subject to liquidity risk, and the Fund may not be able to sell a high-yield bond at the price at which it is currently valued.

•

Interest rate risk - When interest rates increase, fixed-income securities generally will decline in value. Long-term fixed income securities normally have more price volatility than short-term fixed income securities. The value of certain equity investments, such as utilities and real estate-related securities, may also be sensitive to interest rate changes.

•

Investment strategy risk -The Sub-Adviser uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. Investment decisions made by the Sub-Adviser in accordance with these investment strategies may not produce the returns the Sub-Adviser expected, and may cause the Fund's shares to decline in value or may cause the Fund to underperform other funds with similar investment objectives.

•

Issuer risk - The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole. A security's value may decline for reasons that directly relate to the issuer, such as management performance, corporate governance, financial leverage and reduced demand for the issuer's goods or services.

•

Leverage risk - Certain derivative transactions involve the use of leverage and may cause the Fund to liquidate portfolio positions at disadvantageous times to satisfy its obligations. The effect of using leverage is to amplify the Fund's gains and losses in comparison to the amount of the Fund's assets (that is, assets other than borrowed assets) at risk, which may cause the Fund's portfolio to be more volatile. If the Fund uses leverage, the Fund has the risk of capital losses that exceed the net assets of the Fund.

•

Liquidity risk - Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk arises, for example, from small average trading volumes, trading restrictions, or temporary suspensions of trading. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

•

Managed portfolio risk - As an actively managed portfolio, the Fund's portfolio manager(s) make decisions to buy and sell holdings in the Fund's portfolio. Because of this, the value of the Fund's investments could decline because the financial condition of an issuer may change (due to such factors as management performance, reduced demand or overall market changes), financial markets may fluctuate or overall prices may decline, the Fund's Sub-Adviser's investment techniques could fail to achieve the Fund's investment objective or negatively affect the Fund's investment performance, or legislative, regulatory, or tax developments may affect the investment techniques available to the Sub-Adviser of the Fund. There is no guarantee that the investment objective of the Fund will be achieved.

•

Market risk - Portfolio securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic, political, or regulatory conditions, inflation, changes in interest or currency rates or adverse investor sentiment, public health issues, including widespread disease and virus epidemics or pandemics, war, terrorism or natural disasters, among others. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. The values of securities may fall due to factors affecting a particular issuer, industry or the securities market as a whole.

•

Model risk - The Sub-Adviser relies heavily on quantitative models and information and data supplied or made available by third parties ("Models and Data"). Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund's investments. The Fund bears the risk that the proprietary quantitative models used by the portfolio managers will not be successful in identifying securities that will help the Fund achieve its investment objectives, which may cause the Fund to underperform its benchmark or other funds with a similar investment objective. When Models and Data prove to be incorrect or incomplete, including because data is stale, missing or unavailable, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Some of the models used by the Sub-Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend on the accuracy and reliability of the supplied historical data. All models rely on correct data inputs. If incorrect data is entered into even a well-founded model, the resulting information will be incorrect. However, even if data is inputted correctly, "model prices" will often differ substantially from market prices, especially for instruments with complex characteristics, such as derivative instruments. The Fund is unlikely to be successful unless the assumptions underlying the models are realistic and either remain realistic and relevant in the future or are adjusted to account for changes in the overall market environment. If such assumptions are inaccurate or become inaccurate and are not promptly adjusted, it is likely that profitable trading signals will not be generated, and major losses may result. The Sub-Adviser, in its sole discretion, will continue to test, evaluate and add new models, which may result in the modification of existing models from time to time. There can be no assurance that model modifications will enable the Fund to achieve its investment objective.

•

Mortgage-related and other asset-backed securities risk - Rising interest rates tend to extend the duration of mortgage-related and other asset-backed securities, making them more sensitive to changes in interest rates and exhibit increased volatility. When interest rates decline, borrowers may pay off their mortgages or other loans sooner than expected, which can reduce the returns.

•

Prepayment risk - During periods of falling interest rates, a debt security with a high interest rate may be prepaid before its expected maturity date. The Fund may have to reinvest the proceeds in an investment that may have lower yields than the yield on the prepaid debt security. In addition, prepayment rates are difficult to predict and the potential impact of prepayment on the price of a debt instrument depends on the terms of the instrument.

•

Real estate investment risk - Risks of investing in real estate securities include falling property values due to increasing vacancies in rental properties, declining rents resulting from economic, legal, tax, cultural, political or technological developments, lack of liquidity, limited diversification, and sensitivity to certain economic factors such as interest-rate changes and other market conditions. When growth is slowing, demand for property decreases and prices may decline, which could impact the value of real estate investments as well as mortgage-backed securities that may be held by the Fund. Real estate company share prices may drop because of the failure of borrowers to pay their loans and poor management, and residential developers, in particular, could be negatively impacted by falling home prices, slower mortgage origination and rising construction costs. The securities of smaller real estate-related issuers can be more volatile and less liquid than securities of larger issuers and their issuers can have more limited financial resources.

•

REIT investment risk - The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; difficulties in valuing and disposing of real estate; fluctuations in interest rates and property tax rates; shifts in zoning laws; environmental regulations and other governmental action; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; the management skill and creditworthiness of the REIT manager; and other factors. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings of securities and may be more volatile than other securities. REITs could be adversely affected by failure to maintain their exemptions from registration under the Investment Company Act of 1940, as amended, or failure to qualify for the "dividends paid deduction" under the Internal Revenue Code of 1986, as amended, which allows REITs to reduce their corporate taxable income for dividends paid to their shareholders.

•

Sector risk - Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the risk that securities of companies within specific sectors of the economy can perform differently than the overall market. For example, this may be due to changes in the regulatory or competitive environment or changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain sectors than others, the Fund's performance may be more susceptible to any developments which affect those sectors emphasized by the Fund. In addition, the Fund could underperform other funds investing in similar sectors or comparable benchmarks because of the investment manager's choice of securities within such sector.

•

Settlement risk - Settlement risk is the risk that a settlement in a transfer system does not take place as expected. Loan transactions often settle on a delayed basis compared with securities and the Fund may not receive proceeds from the sale of a loan for a substantial period after the sale, potentially impacting the ability of the Fund to make additional investments or meet redemption obligations. It may take longer than seven days for transactions in loans to settle. In order to meet short-term liquidity needs, the Fund may draw on its cash or other short-term positions, maintain short-term or other liquid assets sufficient to meet reasonably anticipated redemptions, or maintain a credit facility.

•

U.S. Government securities risk - Obligations issued by agencies and instrumentalities of the U.S. Government vary in the level of support they receive from the U.S. Government. They may be: (i) supported by the full faith and credit of the U.S. Treasury; (ii) supported by the right of the issuer to borrow from the U.S. Treasury; (iii) supported by the discretionary authority of the U.S. Government to purchase the issuer's obligations; or (iv) supported only by the credit of the issuer. The maximum potential liability of the issuers of some U.S. Government securities may greatly exceed their current resources, or their legal right to receive support from the U.S. Treasury.

•

Volatility risk - The Fund may have investments that appreciate or depreciate significantly in value over short periods of time. This may cause the Fund's net asset value per share to experience significant appreciations or depreciations in value over short periods of time.

•

Portfolio turnover risk - Frequent changes in the securities held by the Fund, including investments made on a shorter-term basis or in derivative instruments or in instruments with a maturity of one year or less at the time of acquisition, may increase transaction costs, which may reduce performance.

•

Forward and futures contract risk - The successful use of forward and futures contracts draws upon the Sub-Adviser's skill and experience with respect to such instruments and are subject to special risks including, but not limited to: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) 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; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Sub-Adviser's inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty, clearing member or clearinghouse will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

•

Swaps risk - Swap agreements are subject to the risks of derivatives, including risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. Swap agreements historically have been OTC, two-party contracts entered into primarily by institutional investors for periods typically ranging from a few weeks to more than one year. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. There are various types of swaps, including but not limited to, total return swaps, credit default swaps and interest rate swaps; all of these and other swaps are derivatives and as such, each is subject to the general risks relating to derivatives described herein. The Dodd-Frank Act mandated a new regulatory framework for trading swaps in the United States. For example, certain standardized swaps are now, and others may in the future be, required to be executed on or subject to the rules of specified trading platforms such as designated contract markets or swap execution facilities and cleared by a central counterparty such as a derivatives clearing organization ("DCO"). Central clearing is intended to reduce the risk of default by the counterparty. However, central clearing may increase the costs of swap transactions. There are also risks introduced of a possible default by the central counterparty or by a clearing member or futures commission merchant through which a swap is submitted for clearing. The process of implementing regulations under the Dodd-Frank Act is ongoing and there may be further changes to the system.
