Series F (Floating Rate Strategies Series)

INVESTMENT OBJECTIVE

Series F seeks to provide a high level of current income while maximizing total return.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. The table below does not take into account any of the fees, expenses or charges associated with variable annuity contracts or variable life insurance policies that use the Fund as an underlying investment option. If such fees, expenses or charges were reflected, the overall expenses would be higher. For more information on these fees, expenses and charges, please refer to your contract or policy prospectus.

ANNUAL FUND OPERATING EXPENSES  (expenses that you pay each year as a percentage of the value of your investment) 

Management Fees	0.65 %
Distribution and/or Service (12b-1) Fees	0.25 %
Other Expenses	0.60 %
Acquired Fund Fees and Expenses	0.04 %
Total Annual Fund Operating Expenses1	1.54 %
Fee Waiver (and/or expense reimbursement)2,3	-0.39 %
Total Annual Fund Operating Expenses After Fee Waiver (and/or expense reimbursement)	1.15 %

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example does not reflect fees, expenses or charges of any variable annuity contract or variable life insurance policy that use the Fund as an underlying investment option, which, if reflected, would increase costs.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reflects expenses whether or not you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although the actual costs may be higher or lower, based on these assumptions your costs would be: 

1 Year	3 Years	5 Years	10 Years
$116	$445	$797	$1,790

The above Example reflects applicable fee waiver/expense reimbursement arrangements for the current duration of the arrangements only, as reflected in the Annual Fund Operating Expenses table above.

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. These costs, which are not reflected in 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 53% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund will, under normal circumstances, invest at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in floating rate senior secured syndicated bank loans, floating rate revolving credit facilities ("revolvers"), floating rate unsecured loans, floating rate asset-backed securities (including floating rate collateralized loan obligations ("CLOs")), other floating rate bonds, loans, notes and other securities (which may include, principally, senior secured, senior unsecured and subordinated bonds), fixed income instruments with respect to which the Fund has entered into derivative instruments to effectively convert the fixed rate interest payments into floating rate income payments, and derivative instruments (based on their notional value for purposes of this 80% strategy) that provide exposure (i.e., economic characteristics similar) to floating rate or variable rate loans, obligations or other securities. The loans in which the Fund will invest, generally made by banks and other lending institutions, are made to (or issued by) corporations, partnerships and other business entities. Floating rate loans feature rates that reset regularly, maintaining a fixed spread over a reference rate, such as the Secured Overnight Financing Rate ("SOFR"), other references rates derived from SOFR or the prime rates of large money-center banks. The interest rates for floating rate loans typically reset quarterly, although rates on some loans may adjust at other intervals.

The Fund invests in other fixed-income instruments of various maturities which may be represented by bonds, debt securities, commercial paper, forwards, derivatives or other similar instruments that Guggenheim Partners Investment Management, LLC, also known as Guggenheim Investments (the "Investment Manager"), believes provide the potential to deliver a high level of current income. Securities in which the Fund invests also may include corporate bonds, convertible securities (including those that are deemed to be "busted" because they are trading well below their equity conversion value), agency and non-agency mortgage-backed securities, asset-backed securities (including collateralized mortgage-backed securities) and CLOs. The Fund may invest in a variety of investment vehicles, such as closed-end funds, exchange-traded funds ("ETFs") and other mutual funds.

The Fund may hold securities of any quality, rated or unrated, including those that are rated below investment grade, or, if unrated, determined by the Investment Manager to be of quality comparable to below investment grade securities (also known as "high yield securities" or "junk bonds") or any other quality. The Fund may hold below investment grade securities with no limit. The Fund may hold non-registered or restricted securities (consisting of securities originally issued in reliance on Rule 144A and Regulation S securities). The Fund may also invest in securities of real estate investment trusts ("REITs") and other real estate companies.

The Fund will principally invest in U.S. dollar denominated loans and other securities of U.S. companies, but may also invest in securities of non-U.S. companies, non-U.S. dollar denominated loans and securities (including, but not limited to, denominated in Euros, British pounds, Swiss francs or Canadian dollars), including loans and securities of emerging market countries, sovereign debt securities and Eurodollar bonds and obligations. The Investment Manager may attempt to reduce foreign currency exchange rate risk by entering into contracts with banks, brokers or dealers to purchase or sell securities or foreign currencies at a future date ("forward contracts").

The Fund also may seek exposures through derivative transactions, including: foreign exchange forward contracts; futures on securities, indices, currencies and other investments; SOFR futures; options; interest rate swaps; cross-currency swaps; total return swaps; and credit default swaps, which may also create economic leverage in the Fund. The Fund may engage in derivative transactions for speculative purposes to enhance total return, to seek to hedge against fluctuations in securities prices, interest rates or currency rates, to change the effective duration of its portfolio, to manage certain investment risks, as a substitute for the purchase or sale of securities or currencies and/or to obtain or replicate market exposure. The Fund may use leverage to the extent permitted by applicable law by entering into reverse repurchase agreements and transactions equivalent to a borrowing for investment purposes.

The Fund also may engage, to the full extent permitted by applicable law, in repurchase agreements, forward commitments, short sales and securities lending. The Fund may, without limitation, seek to obtain exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as dollar rolls).

The Investment Manager's investment philosophy is predicated upon the belief that thorough research and independent thought are rewarded with performance that has the potential to outperform benchmark indexes with both lower volatility and lower correlation of returns as compared to such benchmark indexes.

The Investment Manager may determine to sell a security for several reasons, including but not limited to the following: (1) to adjust the portfolio's average maturity or duration, or to shift assets into or out of higher-yielding securities; (2) if a security's credit rating has been changed, the Investment Manager's credit outlook has changed, or for other similar reasons; (3) to meet redemption requests; (4) to take gains; or (5) due to relative value. Under certain circumstances, the Fund may invest in securities that are in default at the time of purchase. If a security defaults subsequent to purchase by the Fund, the Investment Manager will determine in its discretion whether to hold or dispose of such security. Under adverse or unstable market conditions or abnormal circumstances (for example, in the event of credit events, where it is deemed opportune to preserve gains, or to preserve the relative value of investments, or in the case of large cash inflows or anticipated large redemptions), the Fund can make temporary investments that are inconsistent with the Fund's principal investment strategies and may not be able to pursue or achieve its investment objective.

PRINCIPAL RISKS

The value of an investment in the Fund will fluctuate and is subject to investment risks, which means investors could lose money, including all or part of their investment in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any governmental agency. There is no assurance that the Fund will achieve its investment objective. An investment in the Fund does not constitute a complete investment program. The Fund is subject to certain risks and the principal risks of investing in the Fund are summarized below in alphabetical order, and not in the order of importance or potential exposure. The relative significance of each principal risk summarized below may change over time and you should review each risk carefully because any one or more of these risks may result in losses to the Fund. Please see "Description of Principal Risks" in the Fund's prospectus for a more detailed description of the risks of investing in the Fund.

Asset-Backed Securities Risk-Investors in asset-backed securities, including residential mortgage-backed securities, commercial mortgage-backed securities and other structured finance investments (such as collateralized mortgage obligations), generally receive payments that are part interest and part return of principal. These payments may vary based on the rate at which the underlying borrowers pay off their loans. As a result, asset-backed securities are particularly subject to credit risk and borrower defaults on the obligations underlying the asset-backed security will result in losses. In addition, asset-backed securities are typically particularly sensitive to changes in interest rates, which can cause the prices of asset-backed securities to be increasingly volatile and adversely affect the Fund's holdings of asset-backed securities. Some asset-backed securities, including mortgage-backed securities, may have structures that make their performance based on changes in interest rates and other factors difficult to predict, causing their prices to be volatile. Asset-backed securities are also particularly subject to market, liquidity, valuation, prepayment and extension risks, and are also subject to risk of impairment of the value of the underlying asset. Additional risks relating to investments in asset-backed securities may arise principally because of the type of asset-backed securities in which the Fund invests, with such risks primarily associated with the particular assets collateralizing the asset-backed securities, the structure of such asset-backed securities or the tranche or priority of the asset-backed security held by the Fund.

Collateralized Loan Obligations and Collateralized Debt Obligations Risk-Collateralized loan obligations ("CLOs") bear many of the same risks as other forms of asset-backed securities, including interest rate risk, credit risk and default risk. As they are backed primarily by commercial loans, CLOs also bear many of the same risks as investing in loans directly. However, in addition to the risks associated with investing in commercial loans, the complex structure and highly leveraged nature of a CLO poses additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the Fund may invest in CLOs that are subordinate to other classes; and (iv) the complex structure of the CLO may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. CLOs incur indebtedness by issuing classes or "tranches" that vary in risk and yield. CLOs may experience substantial losses attributable to loan defaults or trading losses. Such losses on the underlying assets are borne first by the holders of subordinate tranches, which may take the form of an equity interest. The Fund's investments in CLOs may decrease in market value or income when the CLO's assets experience loan defaults or credit impairment, losses that exceed the most subordinate tranches, or market anticipation of loan defaults and investor aversion to CLO securities as a class.

Collateralized debt obligations ("CDOs") are structured similarly to CLOs and bear many of the same risks as CLOs, including interest rate risk, credit risk and default risk. CDOs are subject to additional risks because they are backed by pools of assets other than commercial loans, including securities (such as other asset-backed securities), synthetic instruments or bonds, and may be highly leveraged. Like CLOs, losses incurred by a CDO are borne first by holders of the most subordinate tranches. Accordingly, the risks of CDOs depend largely on the type of underlying collateral and the tranche of CDOs in which the Fund invests. Moreover, CDOs that obtain their exposure through synthetic investments are exposed to risks associated with derivative instruments.

The terms of many structured finance investments, including CLOs and CDOs, are tied to SOFR or other reference rates. These relatively new and developing rates may not match the reference rate applicable to the underlying assets related to these investments. These may adversely affect the Fund and its investments in CLOs and CDOs, including their value, volatility and liquidity. CLOs, CDOs and their underlying loan obligations are typically not registered for sale to the public and therefore are subject to certain restrictions on transfer and sale, potentially subjecting them to increased liquidity risk as compared to other types of investments. As a result, the proceeds from the sale of CLO securities may not be readily available to meet the Fund's redemption or other obligations and the Fund may be unable to acquire or dispose of the securities at a price and time that are advantageous to the Fund.

Commercial Mortgage-Backed Securities-Investments in commercial mortgage-backed securities ("CMBS") are backed by commercial mortgage loans that may be secured, for example, by office properties, retail properties, hotels, mixed use properties or multi-family apartment buildings and are particularly subject to the credit risk of the borrower and the tenants of the properties securing the commercial mortgage loans. CMBS are subject to the risks of asset-backed securities generally, in particular credit risk and interest rate risk, and the commercial real estate markets. Economic downturns, tightening lending standards and increased interest and lending rates, developments adverse to the commercial real estate markets, and other developments that limit or reduce the activities of and demand for commercial retail and office spaces adversely impact the value of, and income generated by, such securities.

Commercial Paper Risk-The value of the Fund's investment in commercial paper, which is an unsecured promissory note that generally has a maturity date between one and 270 days and is issued by a U.S. or foreign entity, is susceptible to changes in the issuer's financial condition or credit quality. Investments in commercial paper are usually discounted from their value at maturity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.

Convertible Securities Risk-Convertible securities may be subordinate to other securities. The total return for a convertible security depends, in part, upon the performance of the underlying security into which it can be converted. The value of convertible securities tends to decline as interest rates increase. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. Certain types of convertible securities may decline in value or lose their value entirely in the event that the issuer's financial conditions become significantly impaired.

Counterparty Credit Risk-The Fund makes investments in financial instruments and over-the-counter ("OTC")-traded derivatives involving counterparties to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements (e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes insolvent or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease. Counterparty credit risk also includes the related risk of having concentrated exposure to such a counterparty.

Credit Risk-The Fund could lose money if the issuer or guarantor of a fixed-income or other debt instrument or a counterparty to a derivatives transaction or other transaction is unable or unwilling, or perceived by market participants, rating agencies, pricing services or otherwise to be unable or unwilling, to pay interest or repay principal on time, defaults or otherwise fails to meet its obligations. Actual or perceived changes in economic, social, public health, financial or political conditions in general or that affect a particular type of instrument, issuer, guarantor or counterparty can reduce the ability of the party to meet its obligations, which can affect the credit quality, liquidity and/or value of an instrument. The value of an instrument also may decline for reasons that relate directly to the

issuer, guarantor or counterparty, such as management performance, financial leverage and reduced demand for goods and services or an actual or perceived change in financial condition or reputation. The issuer, guarantor or counterparty could also suffer a rapid decline in credit rating, which would adversely affect the value, price volatility and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Currency Risk-Indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, which would cause a decline in the value of the holdings of the Fund. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political, economic and tax developments in the U.S. or abroad.

Derivatives Risk-Derivatives and other similar instruments (collectively referred to in this paragraph as "derivatives") pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, market conditions and market risk, imperfect correlations with underlying investments or the Fund's other portfolio holdings, high price volatility, lack of availability, counterparty credit, illiquidity, valuation, operational and legal restrictions and risk. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in leverage, which may cause the Fund to be more volatile and riskier than if it had not been leveraged. Changes in the value of a derivative may also create sudden margin delivery or settlement payment obligations for the Fund, which can materially affect the performance of the Fund and its liquidity and other risk profiles. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund's use of derivatives may cause the Fund to realize higher amounts of short term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty credit, legal, liquidity and valuation risks. Certain risks also are specific to the derivatives in which the Fund invests.

Forward Foreign Currency Exchange Contracts Risk-A forward foreign currency exchange contract is an OTC obligation to purchase or sell a specific currency at a future date at a price set at the time of the contract. Foreign currency transactions can be affected unpredictably by intervention (or the failure to intervene) by U.S. or foreign governments or central banks, or by currency controls or political developments. Such events may prevent or restrict the Fund's ability to enter into foreign currency transactions, force the Fund to exit a foreign currency transaction at a disadvantageous time or price or result in penalties for the Fund, any of which may result in a loss to the Fund. A contract to sell a foreign currency would limit any potential gain that might be realized if the value of the currency increases. Suitable hedging transactions may not be available in all circumstances. Engaging in forward foreign currency exchange contracts will subject the Fund to counterparty credit risk and any failure to perform by a counterparty could result in a loss to the Fund.

Dollar Roll Transaction Risk-The Fund may enter into dollar roll transactions, in which the Fund sells a mortgage-backed or other security for settlement on one date and buys back a substantially similar security for settlement at a later date. Dollar rolls involve a risk of loss if the market value of the securities that the Fund is committed to buy declines below the price of the securities the Fund has sold.

Emerging Markets Risk-Investments in or exposure to emerging markets are generally subject to a greater level of the risks associated with investing in or being exposed to developed foreign markets, as emerging markets are considered to be less developed. Furthermore, investments in or exposure to emerging markets are generally subject to risks in addition to the risks associated with investing in foreign securities, including the risks associated with trading in smaller markets, lower volumes of trading, limited information about issuers and securities, being subject to lower levels of government regulation and less extensive and transparent accounting, auditing, recordkeeping, financial reporting and other requirements, and being subject to potential expropriation or nationalization of private properties and other adverse political, economic and social events.

Extension Risk-Certain debt instruments, including mortgage- and other asset-backed securities, are subject to the risk that payments on principal may occur at a slower rate or later than expected. In this event, the expected maturity could lengthen and the Fund's investment may sharply decrease in value and the Fund's income from the investment may quickly decline. These types of instruments are particularly subject to extension risk, and offer less potential for gains, during periods of rising interest rates. In addition, the Fund may be delayed in its ability to reinvest income or proceeds from these instruments in potentially higher yielding investments, which would adversely affect the Fund.

Foreign Securities and Currency Risk-Foreign securities carry unique, additional and heightened risks when compared to U.S. securities, including, but not limited to: currency fluctuations; adverse political (including geopolitical), social and economic developments; trade restrictions (including tariffs) or other government restrictions by the U.S. or other governments; unreliable, untimely or less publicly available information; less government supervision; reporting, accounting, and auditing standards that are not comparable to those in the United States; less liquidity and more volatility; limited legal recourse and higher transactional costs.

High Yield and Unrated Securities Risk-High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") are regarded as predominantly speculative by certain rating agencies with respect to the issuer's continuing ability to meet principal and interest payments. These securities generally present additional risks compared to investment grade bonds and are typically less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, and present more credit and default risk, including risk of loss (which may be substantial or total loss) of income and principal, than investment grade bonds. The price of high yield securities tends to be subject to greater volatility due to issuer-specific factors, such as operating results and outlook, and to real or perceived adverse economic and competitive industry conditions. High yield securities may be issued by companies that are restructuring, are smaller and less credit worthy or are more highly leveraged or indebted than other companies or are financially distressed, and therefore they typically have more difficulty making scheduled payments of principal and interest than issuers of higher rated investments. Under unusual or adverse economic, market or political conditions, high yield securities may be particularly susceptible to default risk and increased default rates. In the event of default, the Fund may incur additional expenses to seek recovery or to negotiate new terms with a defaulting issuer. Based on its investment strategies, a significant portion of the Fund's investments (directly or indirectly) can be comprised of high yield, below investment grade and unrated securities and thus particularly prone to the foregoing risks, which may result in losses to the Fund.

Interest Rate Risk-Fixed-income and other debt instruments are subject to the possibility that interest rates could change (or are expected to change). Changes in interest rates (or the expectation of such changes) can be difficult to forecast and may adversely affect the Fund's investments in these instruments, such as the value or liquidity of, and income generated by, the investments. Interest rates may change as a result of a variety of factors, and the change may be sudden and significant, with unpredictable impacts on the financial markets and the Fund's investments. Fixed-income and other debt instruments with longer durations are more sensitive to changes in interest rates and, thus, subject to more volatility than similar instruments with shorter durations. Generally, when interest rates increase, the values of previously issued fixed-income and other debt instruments decline, sometimes suddenly and significantly. When interest rates decrease, the values of fixed-income and other debt instruments generally rise. During periods of rising interest rates, because changes in interest rates on adjustable rate securities may lag behind changes in market rates, the value of such securities may decline until their interest rates reset to market rates. During periods of declining interest rates, because the interest rates on adjustable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities. The Fund's yield, returns and performance may be adversely affected by changing interest rates and the Fund's net asset value per share may be more volatile during changing interest rate environments. Changes in fiscal, economic, monetary and other policies or measures have in the past, and may in the future, cause or exacerbate the risks associated with changing interest rates. Changes in interest rates may also lead to an increase in Fund redemptions, which may result in high portfolio turnover costs and lower valuations, thereby adversely affecting the Fund's performance.

Investment in Investment Vehicles Risk-The Fund may seek to obtain certain exposure through investments in other investment vehicles. Investing in other investment vehicles, including ETFs, closed-end funds, short-term funds advised by the Investment Manager and/or its affiliates and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles' expenses, which will reduce the Fund's performance. In addition, investments in an ETF or a listed closed-end fund are subject to, among other risks, the risk that the shares may trade at a discount or premium relative to the NAV of the shares and the listing exchange may halt trading of the shares.

Investment in Loans Risk-The Fund may invest in loans directly or indirectly through assignments or participations. Investments in loans, including loan syndicates and other direct lending opportunities, involve special types of risks, including credit risk, interest rate risk, counterparty risk, prepayment risk, risk of subordination to other creditors, extension risk and risk of insufficient or lack of protection under the federal securities law. Loans may offer

a fixed or floating interest rate. Loans are often below investment grade and may be unrated. The Fund's investments in loans can also be difficult to value accurately because of, among other factors, limited public information regarding the loan or the borrowers and may be more susceptible to liquidity risk than fixed-income instruments of similar credit quality and/or maturity. The Fund is also subject to the risk that the value of any collateral for the loan may be insufficient or unavailable to cover the borrower's obligations should the borrower fail to make payments, become insolvent, or otherwise default. This risk is increased if the Fund's loans are secured by a single asset. The Fund may also invest in loans that are not secured by collateral which typically present greater risks than collateralized loans. Transactions in loans are often subject to long settlement periods and often require consent from borrowers and/or an agent acting for the lenders, thus potentially limiting the ability of the Fund to invest sale proceeds in other investments and to use proceeds to meet its current redemption obligations. The Fund thus is subject to the risk of selling other investments at disadvantageous times or prices or taking other actions necessary to raise cash to meet its redemption obligations. Participations in loans may subject the Fund to the credit risk of both the borrower and the seller of the participation and may make enforcement of loan covenants, if any, more difficult for the Fund as legal action may have to go through the seller of the participation (or an agent acting on its behalf). Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower's and the credit group's operations or assets and by providing certain information and consent rights to lenders. In addition to operational covenants, loans and other debt obligations often contain financial covenants, which require a borrower and the related credit group to satisfy certain financial tests at periodic intervals or to maintain compliance with certain financial metrics. The Fund invests predominantly in or is exposed to loans and other similar debt obligations that are sometimes referred to as "covenant-lite" loans or obligations, which generally are loans or other similar debt obligations that lack financial maintenance covenants or possess fewer or contingent financial maintenance covenants and other financial protections for lenders and investors. These "covenant-lite" loans or similar debt obligations are particularly subject to the risks associated with investments in loans as described above.

Investments by Insurance Companies and Accounts and Other Large Shareholders and Redemption Risk-Shares of the Fund are offered as an investment vehicle for certain variable annuity and variable life insurance separate accounts of insurance companies and certain other large investors. The Fund is subject to the risk that an insurance company or account or other large investor will purchase or redeem a large percentage of Fund shares at any time. Any such large investors, in particular separate account(s) of a single insurance company, may comprise a significant portion of the Fund's shareholders. Under certain circumstances, the Fund may also experience frequent shareholder transactions, including by large shareholders. For example, to meet large redemption requests, the Fund may have to hold large uninvested cash positions or sell a significant amount of investments to raise the cash needed to satisfy redemption requests at times when it would not otherwise do so or otherwise at disadvantageous times. In turn, the Fund's performance may suffer, as the Fund may experience increased portfolio turnover and will incur higher transaction costs, realize gains and losses at inopportune times, lose money, hold a less liquid portfolio, or experience other adverse consequences. For example, the sale of portfolio securities will accelerate the realization of taxable capital gains or losses, and purchases or redemptions of a large number of Fund shares relative to the size of the Fund will have adverse tax consequences limiting the use of any capital loss carryforwards and certain other losses to offset any future realized capital gains.

Leverage Risk-The Fund's use of leverage, through borrowings or instruments such as derivatives and reverse repurchase agreements, may cause the Fund to be more volatile and riskier and magnify the Fund's losses to an extent greater than if it had not been leveraged. The use of leverage may also increase the Fund's sensitivity to various risks and interest rate environments.

Liquidity and Valuation Risk-It may be difficult for the Fund to purchase and sell particular investments to meet redemption requests or otherwise within a reasonable time at a fair price, or the price at which it has been valued by the Investment Manager for purposes of the Fund's net asset value, causing the Fund to be less liquid and unable to realize what the Investment Manager believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. Based on its investment strategies, a significant portion of the Fund's investments can be difficult to value and potentially less liquid and thus particularly prone to the foregoing risks. Liquidity and valuation risks are heightened in a changing interest rate or volatile environment, particularly for fixed-income and other debt instruments.

Management Risk-The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns. As a result of these and other factors, the Fund may lose value or fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active and frequent trading that can accompany active management, also called "high turnover," may have a negative impact on performance. Active and frequent trading may result in higher brokerage costs or mark-up charges and tax costs, which are ultimately passed on to shareholders of the Fund.

Market Risk-The value of, or income generated by, the investments held by the Fund may fluctuate rapidly and unpredictably. These fluctuations may be frequent and significant. In addition, the Fund may incur losses as a result of various market and economic factors, such as those affecting (or perceived to affect) individual companies or issuers or particular industries, or from broader influences, such as general market conditions. In addition, responses to government actions or interventions as well as developments related to economic, political (including geopolitical), social, public health, market, extreme weather, natural or man-made disasters or other conditions or events may cause volatility in financial markets and reduced liquidity in equity, credit and/or debt markets, which could adversely impact the Fund and its investments and their value and performance. Under such conditions, the Fund may experience significant redemption activity by shareholders and could be forced to sell portfolio securities or other assets at unfavorable prices in an effort to generate sufficient cash to pay redeeming shareholders. Certain securities may be difficult to value under such conditions. The Fund's investments may perform poorly or underperform the general securities markets or other types of securities.

Prepayment Risk-Certain debt instruments, including loans and mortgage- and other asset-backed securities, are subject to the risk that payments on principal may occur more quickly or earlier than expected. If this occurs, the Fund might be forced to forego future interest income on the principal repaid early and to reinvest income or proceeds at generally lower interest rates, thus reducing the Fund's yield. These types of instruments are particularly subject to prepayment risk, and offer less potential for gains, during periods of declining interest rates.

Real Estate Investments Risk-The Fund may invest in securities of real estate companies and companies related to the real estate industry, including real estate investment trusts ("REITs"), which are subject to the same risks as direct investments in real estate and the real estate market generally. The real estate industry is particularly sensitive to, among other things, economic downturns, changes in interest rates, changes in national, state or local real estate conditions, changes in the availability, cost and terms of mortgages (and other types of financing) and fluctuations in occupancy levels and demand for properties.

Regulatory and Legal Risk-U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations (or amend regulations) and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund, its investments or service providers. These developments impact the investment strategies, performance, costs and operations of the Fund .

Repurchase Agreements and Reverse Repurchase Agreements Risk-In the event of the insolvency of the counterparty to a repurchase agreement or reverse repurchase agreement, recovery of the repurchase price owed to the Fund or, in the case of a reverse repurchase agreement, the securities or other assets sold by the Fund, may be delayed. Because reverse repurchase agreements may be considered to be the practical equivalent of borrowing funds, they constitute a form of leverage. If the Fund reinvests the proceeds of a reverse repurchase agreement at a rate lower than the cost of the agreement, entering into the agreement will lower the Fund's yield.

Residential Mortgage-Backed Securities-Residential mortgage-backed securities ("RMBS") are backed by residential mortgage loans and are particularly subject to the credit risk of the borrower. RMBS are subject to the risks of asset-backed securities generally, in particular credit risk and interest rate risk, and the residential real estate markets. Delinquencies and losses on RMBS generally increase during periods of adverse economic conditions. Investments in non-agency RMBS, which are not guaranteed by the U.S. government or a government sponsored enterprise, are subject to increased interest rate, credit and other risks, such as liquidity and valuation risks.

Restricted Securities Risk-Restricted securities, including those acquired through private placement transactions, generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Securities Lending Risk-Securities lending involves a risk that the borrower may fail to return the securities or deliver the proper amount of collateral, which may result in a loss to the Fund. In the event of bankruptcy of the borrower, the Fund could experience losses or delays in recovering the loaned securities.

Short Sale Risk-Short selling a security involves selling a borrowed security with the expectation that the value of that security will decline so that the security may be purchased at a lower price when returning the borrowed security. The loss on a short sale, which, in some cases, may be theoretically unlimited, may be greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Fund's ability to engage in short selling.

Sovereign Debt Risk-The debt securities issued by sovereign entities may decline as a result of default or other adverse credit event resulting from a sovereign debtor's unwillingness or inability to repay principal and pay interest in a timely manner, which may be affected by a variety of factors, including its cash flow situation, the extent of its reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor's policy toward international lenders, and the political constraints to which a sovereign debtor may be subject. Sovereign debt risk is greater for issuers in emerging markets than issuers in developed countries.

Special Situation Investments/Securities in Default Risk-Investments in the securities and debt of distressed issuers or issuers in default or distressed situations involve far greater risk than investing in issuers whose debt obligations are being met and whose debt trades at or close to its "par" or full value because the investments in the securities and debt of distressed issuers or issuers in default are highly speculative with respect to the issuer's ability to make interest payments and/or to pay its principal obligations in full and/or on time.

When Issued, Forward Commitment and Delayed-Delivery Transactions Risk-When-issued, forward-commitment and delayed-delivery transactions involve a commitment to purchase or sell specific securities at a predetermined price or yield in which payment and delivery take place after the customary settlement period for that type of security. When purchasing securities pursuant to one of these transactions, payment for the securities is not required until the delivery date. However, the purchaser assumes the rights and risks of ownership, including the risks of price and yield fluctuations and the risk that the security will not be issued as anticipated.

PAYMENTS TO INSURANCE COMPANIES AND OTHER FINANCIAL INTERMEDIARIES
