Additional Information About Risks

Like all mutual funds, investing in the Fund involves risk factors and special considerations. The Fund’s risk is defined primarily by its principal investment strategies, which are described earlier in the summary section of this Prospectus, along with descriptions of the Fund’s related risks. Investments in the Fund are not insured against loss of principal. As with any mutual fund, there can be no assurance that the Fund will achieve its investment objectives. Investing in shares of the Fund should not be considered a complete investment program. There is a risk that the share value of the Fund will fluctuate.

One of your most important investment considerations should be balancing risk and return. Different types of investments tend to respond differently to shifts in the economic and financial environment. Diversifying your investments among different asset classes — such as stocks, bonds and cash — and within an asset class — such as small-cap and large-cap stocks — may help you to manage risk and achieve the results you need to reach your financial goals.

The following includes additional information regarding the Fund’s risks that are summarized in the “Principal Risks” for the Fund. Factors that may affect the Fund’s portfolio as a whole are called “principal risks.” Any risks that are discussed below and not included in the “Principal Risks” for the Fund are not considered by the Fund to be principal risks. This summary describes the nature of principal risks and certain additional risks, but is not intended to include every potential risk. The Fund could be subject to additional risks because the types of investments it makes may change over time. The SAI, which is incorporated by reference into this Prospectus, includes more information about the Fund and its investments. The Fund is not intended to be a complete investment program.

Asset-Backed Securities Risk: Because asset-backed securities often are secured by the loans underlying the securities, the Fund may lose money if there are defaults on the loans underlying the securities. Such defaults have increased the risk for asset-backed securities that are secured by home-equity loans related to sub-prime mortgage loans, especially in a declining residential real estate market. Asset-backed securities also may be subject to more rapid repayment than their stated maturity dates indicate, due to changing economic conditions. To maintain its position in such securities, the Fund may reinvest the reductions in principal amounts resulting from the prepayments. Yields on those reinvested amounts are subject to prevailing market rates. Because prepayments of principal generally increase when rates are falling, the Fund generally has to reinvest proceeds from prepayments at lower rates. Investments in asset-backed securities may also be subject to valuation risk.

Counterparty Risk: The Fund may engage in transactions in securities and financial instruments that involve counterparties. Counterparty risk is the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations. In an attempt to limit the counterparty risk associated with such transactions, the Fund conducts business only with financial institutions judged by the Adviser to present acceptable credit risk. For example, repurchase agreements are loans of

money or arrangements under which the Fund purchases securities and the seller agrees to repurchase the securities within a specific time and at a specific price. The repurchase price is generally higher than the Fund’s purchase price, with the difference being income to the Fund. The counterparty’s obligations under the repurchase agreement are collateralized with U.S. Treasury and/or agency obligations with a market value of not less than 100% of the obligations, valued daily. Collateral is held by the Fund’s custodian in a segregated, safekeeping account for the benefit of the Fund. Repurchase agreements afford the Fund an opportunity to earn income at low risk on temporarily available cash. If bankruptcy or insolvency proceedings commence with respect to the seller of the securities before repurchase of the securities under a repurchase agreement, the Fund may encounter delays and incur costs before being able to sell the securities. Such a delay may involve loss of interest or a decline in price of the securities. If a court characterizes the transaction as a loan and the Fund has not perfected a security interest in the securities, the Fund may be required to return the securities to the seller’s estate and be treated as an unsecured creditor of the seller. As an unsecured creditor, the Fund would be at risk of losing some or all of the principal and interest involved in the transaction.

Credit Risk: The value of debt securities owned by the Fund may be affected by the ability of issuers to make principal and interest payments and by the issuer’s or counterparty’s credit quality. If an issuer cannot meet its payment obligations or if its credit rating is lowered, the value of its debt securities may decline. Lower quality bonds are generally more sensitive to these changes than higher quality bonds. Even within securities considered investment grade, differences exist in credit quality and some investment-grade debt securities may have speculative characteristics. A security’s price may be adversely affected by the market’s perception of the security’s credit quality level even if the issuer or counterparty has suffered no degradation in its ability to honor the obligation.

Credit risk varies depending upon whether the issuers of the securities are corporations or domestic or foreign governments or their sub-divisions or instrumentalities and whether the particular note or other instrument held by the Fund has a priority in payment of principal and interest. U.S. government securities are subject to varying degrees of credit risk depending upon whether the securities are supported by the full faith and credit of the United States, supported by the ability to borrow from the U.S. Treasury, supported only by the credit of the issuing U.S. government agency, instrumentality, or corporation, or otherwise supported by the United States. Obligations issued by U.S. government agencies, authorities, instrumentalities or sponsored enterprises, such as Government National Mortgage Association, are backed by the full faith and credit of the U.S. Treasury, while obligations issued by others, such as Federal National Mortgage Association (FNMA), Federal Home Loan Mortgage Corporation (Freddie Mac) and Federal Home Loan Banks (FHLBs), are backed solely by the ability of the entity to borrow from the U.S. Treasury or by the entity’s own resources. No assurance can be given that the U.S. government would provide financial support to U.S. government agencies, authorities, instrumentalities or sponsored enterprises if it is not obligated to do so by law.

Currency Risk: A portion of the Fund’s assets may be quoted or denominated in non-U.S. currencies. These securities may be adversely affected by fluctuations in the relative currency exchange rates and by exchange control regulations. The Fund’s investment performance may be negatively affected by a devaluation of a currency in which the Fund’s investments are quoted or denominated. Further, the Fund’s investment performance may be significantly affected, either positively or negatively, by currency exchange rates because the U.S. dollar value of securities quoted or denominated in another currency will increase or decrease in response to changes in the value of such currency in relation to the U.S. dollar.

Debt Securities Risk: The value of a debt security (and other income-producing securities, such as preferred stocks, convertible preferred stocks, equity-linked notes, and interests in income-producing trusts) changes in response to interest rate changes. In general, the value of a debt security is likely to fall as interest rates rise. This risk is generally greater for obligations with longer maturities or for debt securities that do not pay current interest (such as zero-coupon securities). Debt securities with floating interest rates can be less sensitive to interest rate changes, although, to the extent the Fund’s income is based on short-term interest rates that fluctuate over short periods of time, income received by the Fund may decrease as a result of a decline in interest rates. In addition, the interest rates of floating rate loans typically only adjust to changes in short-term interest rates; long-term interest rates can vary dramatically from short-term interest rates. In response to an interest rate decline, debt securities that provide the issuer with the right to call or redeem the security prior to maturity may be called or redeemed. If a debt security is repaid more quickly than expected, the Fund may not be able to reinvest the proceeds at the same interest rate, reducing the potential for gain. When interest rates increase or for other reasons, debt securities may be repaid more slowly than expected. As a result, the maturity of the debt instrument is extended, increasing the potential for loss. As of the date of this Prospectus, market interest rates in the United States are at or near historic lows, which may increase the Fund’s exposure to risks associated with rising market interest rates.

Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in fixed-income and related markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the fixed-income and related markets. Further, recent and potential future changes in government policy may affect interest rates.

The value of a debt security also depends on the issuer’s credit quality or ability to pay principal and interest when due. The value of a debt security is likely to fall if an issuer or the guarantor of a security is unable or unwilling (or perceived to be unable or unwilling) to make timely principal and/or interest payments or otherwise to honor its obligations, or if the debt security’s rating is downgraded by a credit rating agency. The obligations of issuers (and obligors of asset-backed securities) are subject to bankruptcy, insolvency, and other laws affecting the rights and remedies of creditors. The value of a debt security can also decline in response to other changes in market, economic, industry, political, and regulatory conditions that affect a particular type of debt security or issuer or debt securities generally. The values of many debt securities may fall in response to a general increase in investor risk aversion or a decline in the confidence of investors generally in the ability of issuers to meet their obligations.

Senior loans are subject to the same risks typically associated with debt securities. In addition, senior loans, which typically hold a senior position in the capital structure of a borrower, are subject to the risk that a court could subordinate such loans to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Senior loans are also especially 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.

Derivatives Risk: The Fund may invest in derivatives, which are financial contracts whose value depends on, or is derived from, the value of underlying assets, reference rates, or indices. Derivatives involve the risk that changes in their value may not move as expected relative to the value of the assets, rates, or indices they are designed to track. Derivatives include futures, non-U.S. currency contracts, swap contracts, warrants, and options contracts. Derivatives may relate to securities, interest rates, currencies or currency exchange rates, inflation rates, commodities, and indices.

There are several risks associated with derivatives transactions. The use of derivatives involves risks that are in addition to, and potentially greater than, the risks of investing directly in securities and other more traditional assets. A decision as to whether, when and how to use derivatives involves the exercise of skill and judgment, and even a well conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events. The use of derivative transactions may result in losses greater than if they had not been used, may require the Fund to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment or may cause the Fund to hold a security that it might otherwise sell. The Fund may enter into credit derivatives, such as credit default swaps and credit default index investments, including loan credit default swaps and loan credit default index swaps. The use by the Fund of credit default swaps may have the effect of creating a short position in a security. These investments can create investment leverage and may create additional investment risks that may subject the Fund to greater volatility than investments in more traditional securities. Derivative contracts may expire worthless.

The Fund may invest in derivatives with a limited number of counterparties, and events affecting the creditworthiness of any of those counterparties may have a pronounced effect on the Fund. Derivatives risk is particularly acute in environments (like those of 2008) in which financial services firms are exposed to systemic risks of the type evidenced by the insolvency of Lehman Brothers and subsequent market disruptions. In addition, during those periods, the Fund may have a greater need for cash to provide collateral for large swings in its mark-to-market obligations under the derivatives in which it has invested.

The Fund’s use of derivatives may not be effective or have the desired results. Moreover, suitable derivatives will not be available in all circumstances. For example, the economic costs of taking some derivative positions may be prohibitive, and if a counterparty or its affiliate is deemed to be an affiliate of the Fund, the Fund will not be permitted to trade with that counterparty. In addition, the Adviser may decide not to use derivatives to hedge or otherwise reduce the Fund’s risk exposures, potentially resulting in losses for the Fund.

Swap contracts and other OTC derivatives are highly susceptible to liquidity risk (see “Illiquid and Restricted Securities Risk”) and counterparty risk (see “Counterparty Risk”), and are subject to documentation risks. Because many derivatives have a leverage component ( i.e. , a notional value in excess of the assets needed to establish and/or maintain the derivative position), adverse changes in the value or level

16

of the underlying asset, rate or index may result in a loss substantially greater than the amount invested in the derivative itself. See “Leverage Risk” below.

Derivatives also present other risks described in this section, including securities market risk, illiquid and restricted securities risk, currency risk, credit risk, and counterparty risk. Special tax considerations apply to the Fund’s use of derivatives. See the “Taxation” section below.

As a general matter, when the Fund establishes certain derivative instrument positions, such as certain futures, options and forward contract positions, it will segregate liquid assets (such as cash, U.S. Treasury bonds or commercial paper) equivalent to the Fund’s outstanding obligations under the contract or in connection with the position.

Under recently adopted rules and regulations, transactions in some types of swaps (including interest rate swaps and credit default swaps on North American and European indices) are required to be centrally cleared. In a transaction involving those swaps (“cleared derivatives”), the Fund’s counterparty is a clearing house, rather than a bank or broker. Since the Fund are not members of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives transactions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Clearing members guarantee performance of their clients’ obligations to the clearing house.

In many ways, cleared derivative arrangements are less favorable to mutual funds than bilateral arrangements. For example, the Fund may be required to provide more margin for cleared derivatives transactions than for bilateral derivatives transactions. Also, in contrast to a bilateral derivatives transaction, following a period of notice to the Fund, a clearing member generally can require termination of an existing cleared derivatives transaction at any time or an increase in margin requirements above the margin that the clearing member required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing transactions or to terminate those transactions at any time. Any increase in margin requirements or termination of existing cleared derivatives transactions by the clearing member or the clearing house could interfere with the ability of the Fund to pursue its investment strategy. Further, any increase in margin requirements by a clearing member could expose the Fund to greater credit risk to its clearing member, because margin for cleared derivatives transactions in excess of a clearing house’s margin requirements typically is held by the clearing member. Also, the Fund is subject to risk if it enters into a derivatives transaction that is required to be cleared (or that the Adviser expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund’s behalf. In those cases, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of the transaction, including loss of an increase in the value of the transaction and/or loss of hedging protection. In addition, the documentation governing the relationship between the Fund and clearing members is drafted by the clearing members and generally is less favorable to the Fund than typical bilateral derivatives documentation. For example, documentation relating to cleared derivatives generally includes a one-way indemnity by the Fund in favor of the clearing member for losses the clearing member incurs as the Fund’s clearing member and typically does not provide the Fund any remedies if the clearing member defaults or becomes insolvent. While futures contracts entail similar risks, the risks likely are more pronounced for cleared swaps due to their more limited liquidity and market history.

Some types of cleared derivatives are required to be executed on an exchange or on a swap execution facility. A swap execution facility is a trading platform where multiple market participants can execute derivatives by accepting bids and offers made by multiple other participants in the platform. While this execution requirement is designed to increase transparency and liquidity in the cleared derivatives market, trading on a swap execution facility can create additional costs and risks for the Fund. For example, swap execution facilities typically charge fees, and if the Fund executes derivatives on a swap execution facility through a broker intermediary, the intermediary may impose fees as well. Also, the Fund may indemnify a swap execution facility, or a broker intermediary who executes cleared derivatives on a swap execution facility on the Fund’s behalf, against any losses or costs that may be incurred as a result of the Fund’s transactions on the swap execution facility.

These and other new rules and regulations could, among other things, further restrict the Fund’s ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund, increasing margin or capital requirements, or otherwise limiting liquidity or increasing transaction costs. These regulations are new and evolving, so their potential impact on the Fund and the financial system are not yet known. While the new regulations and central clearing of some derivatives transactions are designed to reduce systemic risk (i.e., the risk that the interdependence of large derivatives dealers could cause them to suffer liquidity, solvency or other challenges simultaneously), there is no assurance that the new clearing mechanisms will achieve that result, and in the meantime, as noted above, central clearing and related requirements expose the Fund to

17

new kinds of risks and costs. In addition, the SEC recently proposed a rule under the 1940 Act regulating the use by registered investment companies of derivatives and many related instruments. That rule, if adopted as proposed, would, among other things, restrict the Fund’s ability to engage in derivatives transactions or so increase the cost of derivatives transactions that the Fund would be unable to implement its investment strategy.

Exchange-Traded Funds (“ETF”) Risk: The value of ETFs can be expected to increase and decrease in value in proportion to increases and decreases in the indices that they are designed to track. The volatility of different index tracking stocks can be expected to vary in proportion to the volatility of the particular index they track. ETFs are traded similarly to stocks of individual companies. Although an ETF is designed to provide investment performance corresponding to its index, it may not be able to exactly replicate the performance of its index because of its operating expenses and other factors.

Extension Risk: When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations 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 Sector Risk: Investments in the financial services sector may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign economies and general economic cycles, fiscal and monetary policy, adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.

Fixed Income Market Risk: Fixed income securities markets may, in response to governmental intervention, economic or market developments (including potentially a reduction in the number of broker-dealers willing to engage in market-making activity), or other factors, experience periods of increased volatility and reduced liquidity. During those periods, the Fund may experience increased levels of shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices. Fixed income securities may be difficult to value during such periods. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to maintain historically low interest rates by purchasing bonds. Steps by those regulators to curtail or “taper” such activities could result in the effects described above, and could have a material adverse effect on prices for fixed income securities and on the management of the Fund

Focused Investment Risk — Senior Loans: The Fund’s investments in Senior Loans arranged through private negotiations between a Borrower and several financial institutions may expose the Fund to risks associated with the financial services industry. Financial services companies are subject to extensive government regulation, which can limit both the amounts and types of loans and other financial commitments they can make and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change. Because financial services companies are highly dependent on short-term interest rates, they can be adversely affected by downturns in the U.S. and foreign economies or changes in banking regulations. Credit losses resulting from financial difficulties of borrowers can negatively affect financial services companies. Insurance companies can be subject to severe price competition. The financial services industry is currently undergoing relatively rapid change as existing distinctions between financial service segments become less clear. For instance, recent business combinations have included insurance, finance, and securities brokerage under single ownership. Some primarily retail corporations have expanded into the securities and insurance industries. Moreover, the federal laws generally separating commercial and investment banking have been repealed. These changes may make it more difficult for the Adviser to analyze loans in this industry. Additionally, the recently increased volatility in the financial markets and implementation of the recent financial reform legislation may affect the financial services industry as a whole in ways that may be difficult to predict.

Hedging Risk: There are several risks in connection with the use by the Fund of futures contracts and related options as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the futures contracts and options and movements in the underlying securities or index or movements in the prices of the Fund’s securities which are the subject of a hedge. The Adviser will, however, attempt to reduce this risk by purchasing and selling, to the extent possible, futures contracts and related options on securities and indices the movements of which will, in its judgment, correlate closely with movements in the prices of the underlying securities or index and the Fund’s portfolio securities sought to be hedged. Successful use of futures contracts and options by the Fund for hedging purposes is also subject to the Adviser’s ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has purchased puts on futures contracts to hedge its portfolio against a decline in the market, the securities or index on which the puts are

18

Table of Contents

Highland Floating Rate Fund

purchased may increase in value and the value of securities held in the portfolio may decline. If this occurred, the Fund would lose money on the puts and also experience a decline in the value of its portfolio securities. In addition, the prices of futures, for a number of reasons, may not correlate perfectly with movements in the underlying securities or index due to certain market distortions. First, all participants in the futures market are subject to margin deposit requirements. Such requirements may cause investors to close futures contracts through offsetting transactions which could distort the normal relationship between the underlying security or index and futures markets. Second, the margin requirements in the futures markets are less onerous than margin requirements in the securities markets in general, and as a result the futures markets may attract more speculators than the securities markets do. Increased participation by speculators in the futures markets may also cause temporary price distortions. Due to the possibility of price distortion, even a correct forecast of general market trends by the Adviser still may not result in a successful hedging transaction over a very short time period. In addition, to maintain margin requirements, the Fund may have to sell portfolio securities at disadvantageous prices or times because it may not be possible to liquidate a position at a reasonable price. The earmarking of such assets also will have the effect of limiting the Fund’s ability otherwise to invest those assets. Special tax considerations apply to the Fund’s hedging transactions. See the “Taxation” section below.

High Yield Debt Securities Risk: Below investment grade securities (also known as “high-yield securities” or “junk securities”) may be fixed or variable rate obligations and are rated below investment grade (Ba/BB or lower) by a nationally recognized statistical rating organization or are unrated but deemed by the Adviser to be of comparable quality. Such securities should be considered speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. High-yield debt securities are frequently issued by corporations in the growth stage of their development, but also may be issued by established companies. High-yield securities held by the Fund may include securities received as a result of a corporate reorganization or issued as part of a corporate takeover.

Below investment grade securities have greater credit and liquidity risk than more highly rated obligations and are generally unsecured and may be subordinate to other obligations of the obligor. The lower rating of high-yield securities reflects a greater possibility that adverse changes in the financial condition of the issuer or in general economic conditions (including, for example, a substantial period of rising interest rates or declining earnings) or both may impair the ability of the issuer to make payment of principal and interest. Many issuers of high-yield securities are highly leveraged and their relatively high debt to equity ratios create increased risks that their operations might not generate sufficient cash flow to service their obligations. Overall declines in the below investment grade bond market and other markets may adversely affect such issuers by inhibiting their ability to refinance their obligations at maturity. Investments in obligations of issuers that are generally trading at significantly higher yields than had been historically typical of the applicable issuer’s obligations may include debt obligations that have a heightened probability of being in covenant or payment default in the future. Such investments generally are considered speculative. The repayment of defaulted obligations is subject to significant uncertainties. Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. Typically such workout or bankruptcy proceedings result in only partial recovery of cash payments or an exchange of the defaulted security for other debt or equity securities of the issuer or its affiliates, which may in turn be illiquid or speculative. High-yield securities will be subject to certain additional risks to the extent that such obligations may be unsecured and subordinated to substantial amounts of senior indebtedness, all or a significant portion of which may be secured. Moreover, such obligations may not be protected by financial covenants or limitations upon additional indebtedness and are unlikely to be secured by collateral. See “Taxation” below and “Income Tax Considerations” in the SAI for a discussion of special tax consequences associated with certain below investment grade securities. There is no limit on the percentage of assets that the Fund may invest in Senior Loans and other securities that are rated below investment grade or that are unrated but of comparable quality.

Illiquid and Restricted Securities Risk: Illiquid investments may be difficult to resell at approximately the price they are valued in the ordinary course of business within seven days. When investments cannot be sold readily at the desired time or price, the Fund may have to accept a much lower price, may not be able to sell the investment at all or may be forced to forego other investment opportunities, all of which may adversely impact the Fund’s returns. Illiquid investments also may be subject to valuation risk. Restricted securities (including Rule 144A securities) may be subject to legal restraints on resale and, therefore, are typically less liquid than other securities. The prices received from selling restricted securities in privately negotiated transactions may be less than those originally paid by the Fund. Investors in restricted securities may not benefit from the same investor protections as publicly traded securities.

Interest Rate Risk: When interest rates decline, the value of fixed rate securities already held by the Fund can be expected

19

Table of Contents

More on Strategies, Risks and Disclosure of Portfolio Holdings

to rise. Conversely, when interest rates rise, the value of existing fixed-rate portfolio securities can be expected to decline. To the extent the Fund invests in fixed-rate debt securities with longer maturities, the Fund is subject to greater interest rate risk than funds investing solely in shorter-term fixed-rate debt securities. In addition, the interest rates of floating rate loans typically only adjust to changes in short-term interest rates; long-term interest rates can vary dramatically from short-term interest rates. In a period of rising interest rates, the higher cost of any leverage employed by the Fund and/or increasing defaults by issuers of high-yield securities would likely exacerbate any decline in the Fund’s NAV. If an issuer of a debt security containing a redemption or call provision exercises either provision in a declining interest rate market, the Fund would likely replace the security with a security having a lower interest rate, which could result in a decreased return for shareholders. To the extent that changes in market rates of interest are reflected not in a change to a base rate (such as LIBOR) but in a change in the spread over the base rate, which is payable on loans of the type and quality in which the Fund invests, the Fund’s NAV could be adversely affected. This is because the value of a Senior Loan is partially a function of whether the Senior Loan is paying what the market perceives to be a market rate of interest, given its individual credit and other characteristics. However, unlike changes in market rates of interest for which there is generally only a temporary lag before the portfolio reflects those changes, changes in a Senior Loan’s value based on changes in the market spread on Senior Loans in the Fund’s portfolio may be of longer duration.

Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call features, among other characteristics. Duration is useful primarily as a measure of the sensitivity of a fixed income security’s market price to interest rate (i.e. yield) movements. All other things remaining equal, for each one percentage point increase in interest rates, the value of a portfolio of fixed income investments would generally be expected to decline by one percent for every year of the portfolio’s average duration above zero. For example, the value of a portfolio of fixed income securities with an average duration of three years would generally be expected to decline by approximately 3% if interest rates rose by one percentage point.

To the extent the Fund purchases securities with borrowed funds, its net assets will tend to increase or decrease at a greater rate than if borrowed funds are not used. The level of interest rates generally, and the rates at which the Fund may be borrowed in particular, could affect the operating results of the Fund. If the interest expense on borrowings were to exceed the net return on the portfolio securities purchased with borrowed funds, the Fund’s use of leverage would result in a lower rate of return than if the Fund were not leveraged.

If the amount of borrowings that the Fund may have outstanding at any one time is large in relation to its capital, fluctuations in the market value of the Fund’s portfolio will have disproportionately large effects in relation to the Fund’s capital and the possibilities for profit and the risk of loss will therefore be increased. Any investment gains made with the additional monies borrowed will generally cause the NAV of the Fund to rise more rapidly than would otherwise be the case. Conversely, if the investment performance of the investments acquired with borrowed money fails to cover their cost to the Fund, the NAV of the Fund will generally decline faster than would otherwise be the case. If the Fund employs leverage, the Adviser will benefit because the Fund’s Average Daily Managed Assets, as defined below, will increase with leverage and the Adviser is compensated based on a percentage of Average Daily Managed Assets.

Under the terms of any credit facility, the Fund may be required to, among other things, pledge some or all of its assets, limit its ability to pay distributions in certain circumstances, incur additional debts and engage in certain transactions. Such agreements could limit the Fund’s ability to pursue its investment strategies. The terms of any credit facility may be more restrictive than those described.

Limited Information Risk: The types of Senior Loans in which the Fund will invest may not have been rated by a NRSRO, have not been registered with the SEC or any state securities commission, and have not been listed on any national securities exchange. Although the Fund will generally have access to financial and other information made available to the Lenders in connection with Senior Loans, the amount of public information available with respect to Senior Loans will generally be less extensive than that available for rated, registered or exchange listed securities. As a result, the performance of the Fund and their ability to meet their respective investment objective is more dependent on the analytical ability of the Adviser than would be the case for an investment company that invests primarily in rated, registered or exchange-listed securities.

Liquidity Risk: Liquidity risk is the risk that low trading volume, lack of a market maker, large position size, or legal restrictions (including daily price fluctuation limits or “circuit breakers”) limits or prevents the Fund from selling particular securities or unwinding derivative positions at desirable prices. The Fund is also exposed to liquidity risk when it has an obligation to purchase particular securities (e.g., as a result of entering into reverse repurchase agreements, writing a put, or closing a short position). When there is no willing buyer or investments cannot be readily sold or closed out, the Fund may have to sell at a lower price than the price at which the Fund is carrying the investments or may not be

able to sell the investments at all, each of which would have a negative effect on the Fund’s performance. Although most of the Fund’s investments must be liquid at the time of investment, investments may become illiquid after purchase by the Fund, particularly during periods of market turmoil.

Management Risk: The Fund is subject to management risk because it relies on the Adviser’s ability to achieve its investment objective. The Fund runs the risk that the Adviser’s investment techniques will fail to produce desired results and cause the Fund to incur significant losses. The Adviser also may fail to use derivatives effectively, choosing to hedge or not to hedge positions at disadvantageous times. In addition, if one or more key individuals leave, the Adviser may not be able to hire qualified replacements or may require an extended time to do so. This situation could prevent the Fund from achieving its investment objectives. The Fund’s portfolio managers use quantitative analyses and/or models. Any imperfections or limitations in such analyses and models could affect the ability of the portfolio managers to implement strategies. By necessity, these analyses and models make simplifying assumptions that limit their efficacy. Models that appear to explain prior market data can fail to predict future market events. Further, the data used in models may be inaccurate and/or it may not include the most recent information about a company or a security.

Non-Diversification Risk: Due to the nature of the Fund’s investment strategy and its non-diversified status (for purposes of the 1940 Act), the Fund may invest a greater percentage of its assets in the securities of fewer issuers than a “diversified” fund, and accordingly may be more vulnerable to changes in the value of those issuers’ securities. The Fund that invests in the securities of a limited number of issuers is particularly exposed to adverse developments affecting those issuers, and a decline in the market value of a particular security held by the Fund is likely to affect the Fund’s performance more than if the Fund invested in the securities of a larger number of issuers.

Non-Payment Risk: Debt instruments are subject to the risk of non-payment of scheduled interest and/or principal. Non-payment would result in a reduction of income to the Fund, a reduction in the value of the security experiencing non-payment and a potential decrease in the NAV of the Fund. There can be no assurance that the liquidation of any collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated. Moreover, as a practical matter, most borrowers cannot satisfy their debts by selling their assets. Borrowers pay their debts from the cash flow they generate. This is particularly the case for borrowers that are highly leveraged. If the borrower’s cash flow is insufficient to pay its debts as they come due, the borrower is far more likely to seek to restructure its debts than it is to sell off assets to pay its debts. Borrowers may try to restructure their debts either by seeking protection from creditors under Chapter 11 of the U.S. Bankruptcy Code (the “Bankruptcy Code”) or negotiating a work out. In the event of bankruptcy of a borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a debt security. The agent generally is responsible for determining that the lenders have obtained a perfected security interest in the collateral securing the debt security. If a borrower files for protection from creditors under Chapter 11 of the Bankruptcy Code, the Bankruptcy Code will impose an automatic stay that prohibits the agent from liquidating collateral. The agent may ask the bankruptcy court to lift the stay. As a practical matter, the court is unlikely to lift the stay if it concludes that the borrower has a chance to emerge from the reorganization proceedings and the collateral is likely to hold most of its value. If the lenders have a perfected security interest, the debt security will be treated as a separate class in the reorganization proceedings and will retain a priority interest in the collateral. Chapter 11 reorganization plans typically are the product of negotiation among the borrower and the various creditor classes. Successful negotiations may require the lenders to extend the time for repayment, change the interest rate or accept some consideration in the form of junior debt or equity securities. A work out outside of bankruptcy may produce similar concessions by senior lenders.

Non-U.S. Securities and Emerging and Developing Markets Risk: Investing in non-U.S. securities involves additional and more varied risks than investing in U.S. investments, including, but not limited to: fluctuations in foreign exchange rates (for non-U.S. securities not denominated in U.S. dollars); future foreign economic, financial, political and social developments; different legal systems; the possible imposition of exchange controls or other foreign governmental laws or restrictions; lower trading volume; much greater price volatility and illiquidity of certain non-U.S. securities markets; different trading and settlement practices; less governmental supervision; changes in currency exchange rates; high and volatile rates of inflation; fluctuating interest rates; less publicly available information; and different accounting, auditing and financial recordkeeping standards and requirements.

Because non-U.S. issuers are not generally subject to uniform accounting, auditing and financial reporting standards and practices comparable to those applicable to U.S. issuers, there may be less publicly available information about certain non-U.S. issuers than about U.S. issuers. Evidence of securities ownership may be uncertain in many foreign countries. Securities of non-U.S. issuers are generally less liquid than securities of comparable U.S. issuers. In certain

countries, there is less government supervision and regulation of stock exchanges, brokers and listed companies than in the U.S. In addition, with respect to certain foreign countries, especially emerging market countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, war, terrorism, nationalization, limitations on the removal of funds or other assets or diplomatic developments which could affect U.S. investments in those countries. Commissions (and other transaction costs) for non-U.S. securities are generally higher than those on U.S. securities. In addition, it is expected that the expenses for custodian arrangements of the Fund’s non-U.S. securities will be somewhat greater than the expenses for a fund that invests primarily in domestic securities. Certain investments in non-U.S. securities may also be subject to foreign withholding and other taxes on interest, dividends, capital gains or other income or proceeds. Those taxes will reduce the Fund’s yield on any such securities.

The value of the non-U.S. securities held by the Fund that are not U.S. dollar-denominated may be significantly affected by changes in currency exchange rates. The U.S. dollar value of a foreign denominated non-U.S. security generally decreases when the value of the U.S. dollar rises against the foreign currency in which the security is denominated and tends to increase when the value of the U.S. dollar falls against such currency. Currencies of certain countries may be volatile and therefore may affect the value of securities denominated in such currencies, which means that the Fund’s NAV or current income could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, the value of the Fund’s assets may be affected by losses and other expenses incurred in converting between various currencies in order to purchase and sell foreign denominated non-U.S. securities, and by currency restrictions, exchange control regulation, currency devaluations and political and economic developments. The foregoing risks often are heightened for investments in smaller, emerging capital markets. In addition, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rates of inflation, capital reinvestment, resources, self-sufficiency and balance of payments position.

As a result of these potential risks, the Adviser may determine that, notwithstanding otherwise favorable investment criteria, it may not be practicable or appropriate to invest in a particular country. The Fund may invest in countries in which foreign investors, including the Adviser have had no or limited prior experience.

Investing in securities of issuers tied economically to emerging markets entails all of the risks of investing in securities of non-U.S. issuers detailed above to a heightened degree. These heightened risks include: (i) greater risks of expropriation, confiscatory taxation, nationalization, and less social, political and economic stability; (ii) the smaller size of the markets for such securities and a lower volume of trading, resulting in lack of liquidity and in price volatility; (iii) greater fluctuations in currency exchange rates; and (iv) certain national policies that may restrict the Fund’s investment opportunities, including restrictions on investing in issuers or industries deemed sensitive to relevant national interests.

Ongoing Monitoring Risk: On behalf of the several Lenders, the Agent generally will be required to administer and manage the Senior Loans and, with respect to collateralized Senior Loans, to service or monitor the collateral. In this connection, the valuation of assets pledged as collateral will reflect market value and the Agent may rely on independent appraisals as to the value of specific collateral. The Agent, however, may not obtain an independent appraisal as to the value of assets pledged as collateral in all cases. The Fund normally will rely primarily on the Agent (where the Fund is a Primary Lender or owns an Assignment) or the selling Lender (where the Fund owns a Participation) to collect principal of and interest on a Senior Loan. Furthermore, the Fund usually will rely on the Agent (where the Fund is a Primary Lender or owns an Assignment) or the selling Lender (where the Fund owns a Participation) to monitor compliance by the Borrower with the restrictive covenants in the Loan Agreement and notify the Fund of any adverse change in the Borrower’s financial condition or any declaration of insolvency. Collateralized Senior Loans will frequently be secured by all assets of the Borrower that qualify as collateral, which may include common stock of the Borrower or its subsidiaries. Additionally, the terms of the Loan Agreement may require the Borrower to pledge additional collateral to secure the Senior Loan, and enable the Agent, upon proper authorization of the Lenders, to take possession of and liquidate the collateral and to distribute the liquidation proceeds pro rata among the Lenders. If the terms of a Senior Loan do not require the Borrower to pledge additional collateral in the event of a decline in the value of the original collateral, the Fund will be exposed to the risk that the value of the collateral will not at all times equal or exceed the amount of the Borrower’s obligations under the Senior Loan. Lenders that have sold Participation interests in such Senior Loan will distribute liquidation proceeds received by the Lenders pro rata among the holders of such Participations. Unless, under the terms of the loan, the Fund has direct recourse against the Borrower, the Fund may have to rely on the Agent or other financial intermediary to apply appropriate credit remedies against a Borrower. The Adviser will also monitor these aspects of the Fund’s investments and, where the Fund is a Primary Lender or own an Assignment, will be directly involved with the Agent and the other Lenders regarding the exercise of credit remedies.

Operational and Technology Risk: The Fund, its service providers, and other market participants increasingly depend on complex information technology and communications systems to conduct business functions. These systems are subject to a number of different threats or risks that could adversely affect the Fund and its shareholders, despite the efforts of the Fund and its service providers to adopt technologies, processes, and practices intended to mitigate these risks.

For example, unauthorized third parties may attempt to improperly access, modify, disrupt the operations of, or prevent access to these systems of the Fund, the Fund’s service providers, counterparties, or other market participants or data within them (a “cyber-attack”). Power or communications outages, acts of god, information technology equipment malfunctions, operational errors, and inaccuracies within software or data processing systems may also disrupt business operations or impact critical data. Market events also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the Fund’s operations.

Cyber-attacks, disruptions, or failures that affect the Fund’s service providers or counterparties may adversely affect the Fund and their shareholders, including by causing losses for the Fund or impairing Fund operations. For example, the Fund’s or their service providers’ assets or sensitive or confidential information may be misappropriated, data may be corrupted, and operations may be disrupted (e.g., cyber-attacks or operational failures may cause the release of private shareholder information or confidential Fund information, interfere with the processing of shareholder transactions, impact the ability to calculate the Fund’s NAV, and impede trading). In addition, cyber-attacks, disruptions, or failures may cause reputational damage and subject the Fund or their service providers to regulatory fines, litigation costs, penalties or financial losses, reimbursement or other compensation costs, and/or additional compliance costs. While the Fund and its service providers may establish business continuity and other plans and processes to address the possibility of cyber-attacks, disruptions, or failures, there are inherent limitations in such plans and systems, including that they do not apply to third parties, such as other market participants, as well as the possibility that certain risks have not been identified or that unknown threats may emerge in the future.

Similar types of operational and technology risks are also present for issuers of the Fund’s investments, which could have material adverse consequences for such issuers, and may cause the Fund’s investments to lose value. In addition, cyber-attacks involving a counterparty of the Fund could affect such counterparty’s ability to meet its obligations to the Fund, which may result in losses to the Fund and its shareholders. Furthermore, as a result of cyber-attacks, disruptions, or failures, an exchange or market may close or issue trading halts on specific securities or the entire market, which may result in the Fund being, among other things, unable to buy or sell certain securities or financial instruments or unable to accurately price its investments. The Fund cannot directly control any cybersecurity plans and systems put in place by its service providers, Fund counterparties, issuers in which the Fund invests, or securities markets and exchanges

Options Risk: The use of options is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objectives. A transaction in options or securities may be unsuccessful to some degree because of market behavior or unexpected events.

When the Fund writes a covered call option, the Fund forgoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but retains the risk of loss should the price of the underlying security decline. The writer of an option has no control over the time when it may be required to fulfill its obligation and once an option writer has received an exercise notice, it must deliver the underlying security at the exercise price.

When the Fund writes a covered put option, the Fund bears the risk of loss if the value of the underlying stock declines below the exercise price minus the put premium. If the option is exercised, the Fund could incur a loss if it is required to purchase the stock underlying the put option at a price greater than the market price of the stock at the time of exercise plus the put premium the Fund received when it wrote the option. Special tax rules apply to the Fund’s or an underlying fund’s transactions in options, which could increase the amount of taxes payable by shareholders. While the Fund’s potential gain in writing a covered put option is limited to distributions earned on the liquid assets securing the put option plus the premium received from the purchaser of the put option, the Fund risks a loss equal to the entire exercise price of the option minus the put premium.

Payment-in-Kind Securities Risk is the risk that the value of payment-in-kind securities (“PIKs”) held by the Fund may be more sensitive to fluctuations in interest rates than other securities. PIKs pay all or a portion of their interest or dividends in the form of additional securities. Federal tax law

23

More on Strategies, Risks and Disclosure of Portfolio Holdings

requires that the interest on PIK bonds be accrued as income to the Fund regardless of the fact that the Fund will not receive cash until such securities mature. Since the income must be distributed to shareholders, the Fund may be forced to liquidate other securities in order to make the required distribution. Additionally, the deferred nature of payments on PIKs creates specific risks.

Interest payments deferred on a PIK are subject to the risk that the borrower may default when the deferred payments are due in cash at the maturity of the loan. Further, the interest rates on PIKs are generally higher to reflect the time-value of money on deferred interest payments and the higher credit risk of borrowers who may need to defer interest payments. The values of PIKs may be less reliable because the accruals require judgments about ultimate collectability of the deferred payments and the value of the associated collateral. An election to defer PIK interest payments by adding them to principal increases the Fund’s net assets (as income is generally distributed at least annually) and, thus, may increase future management fees to the Adviser. The deferral of interest on a PIK increases its loan-to-value ratio, which is a measure of the riskiness of a loan. Even if conditions for income accrual under GAAP are satisfied, a borrower could still default when actual payment is due upon maturity.

Portfolio Turnover Risk: A high rate of portfolio turnover ( i.e. , 100% or more) will result in increased transaction costs for the Fund in the form of increased dealer spreads and brokerage commissions. Greater transaction costs may reduce Fund performance. High portfolio turnover also may result in increased realization of net short-term capital gains (which are taxable to shareholders as ordinary income when distributed to them), higher taxable distributions and lower the Fund’s after-tax performance. The Fund’s annual portfolio turnover rate may vary greatly from year to year.

Prepayment Risk: Borrowers may pay back principal before the scheduled due date. Such prepayments may require the Fund to replace a debt security with a lower-yielding security. During periods of falling interest rates, issuers of debt securities may repay higher rate securities before their maturity dates. This may cause the Fund to lose potential price appreciation and to be forced to reinvest the unanticipated proceeds at lower interest rates. This may adversely affect the NAV of the Fund’s shares.

Regulatory Risk: Legal, tax and regulatory changes could occur and may adversely affect the Fund and their ability to pursue its investment strategies and/or increase the costs of implementing such strategies. New (or revised) laws or regulations may be imposed by the CFTC, the SEC, the IRS, the U.S. Federal Reserve or other banking regulators, other governmental regulatory authorities or self-regulatory organizations that supervise the financial markets that could adversely affect the Fund. In particular, these agencies are empowered to promulgate a variety of new rules pursuant to financial reform legislation in the United States. The Fund also may be adversely affected by changes in the enforcement or interpretation of existing statutes and rules by these governmental regulatory authorities or self-regulatory organizations.

To the extent that legislation or state or federal regulators impose additional requirements or restrictions with respect to the ability of financial institutions to make loans in connection with highly leveraged transactions, the availability of Senior Loan interests for investment by the Fund may be adversely affected. To the extent that legislation or state or federal regulators impose additional requirements or restrictions with respect to the ability of the Fund to invest in the assets of distressed companies, the availability of distressed company interests for investment by the Fund may be adversely affected. In addition, such requirements or restrictions may reduce or eliminate sources of financing for affected Borrowers. Further, to the extent that legislation or federal or state regulators require such institutions to dispose of Senior Loan interests relating to highly leveraged transactions or subject such Senior Loan interests to increased regulatory scrutiny, such financial institutions may determine to sell Senior Loan interests in a manner that results in a price that, in the opinion of the Adviser, is not indicative of fair value. Were the Fund to attempt to sell a Senior Loan interest at a time when a financial institution was engaging in such a sale with respect to the Senior Loan interest, the price at which the Fund could consummate such a sale might be adversely affected.

Risk of Substantial Redemptions: If substantial numbers of shares in the Fund were to be redeemed at the same time or at approximately the same time, the Fund might be required to liquidate a significant portion of its investment portfolio quickly to meet the redemptions. The Fund might be forced to sell portfolio securities at prices or at times when it would otherwise not have sold them, resulting in a reduction in the Fund’s NAV per share; in addition, a substantial reduction in the size of the Fund may make it difficult for the Adviser to execute its investment program successfully for the Fund for a period following the redemptions. If substantial, unexpected redemptions occur, the Fund could experience higher expenses than those shown in the Annual Fund Operating Expenses Tables.

Securities Lending Risk: The Fund will continue to receive interest on any securities loaned while simultaneously earning interest on the investment of the cash collateral in short-term money market instruments. However, the Fund will normally pay lending fees to broker-dealers and related expenses from the interest earned on such invested

24

collateral. Any decline in the value of a portfolio security that occurs while the security is out on loan is borne by the Fund, and will adversely affect performance. There may be risks of delay in receiving additional collateral or risks of delay in recovery of the securities, loss of rights in the collateral should the borrower of the securities fail financially and possible investment losses in the investment of collateral. Any loan may be terminated by either party upon reasonable notice to the other party.

Securities Market Risk: The value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting particular companies or the securities markets generally. The profitability of the Fund substantially depends upon the Adviser’s ability to correctly assess the future price movements of stocks, bonds, loans, options on stocks, and other securities and the movements of interest rates. The Adviser cannot guarantee that it will be successful in accurately predicting price movements.

The market prices of equities may decline for reasons that directly relate to the issuing company (such as poor management performance or reduced demand for its goods or services), factors that affect a particular industry (such as a decline in demand, labor or raw material shortages, or increased production costs) or general market conditions not specifically related to a company or industry (such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally). See also “Debt Securities Risk” and “Fixed Income Market Risk” above.

As a result of the nature of the Fund’s investment activities, it is possible that the Fund’s financial performance may fluctuate substantially from period to period. Additionally, at any point in time an investment in the Fund may be worth less than the original investment, even after taking into account the reinvestment of dividends and distributions.

Senior Loans Risk: Senior Loans may not be rated by a rating agency, registered with the Securities and Exchange Commission or any state securities commission or listed on any national securities exchange. Therefore, there may be less publicly available information about them than for registered or exchange-listed securities. The risks associated with Senior Loans are similar to the risks of below investment grade securities. Moreover, any specific collateral used to secure a loan may decline in value or lose all its value or become illiquid, which would adversely affect the loan’s value. Economic and other events, whether real or perceived, can reduce the demand for certain Senior Loans or Senior Loans generally, which may reduce market prices and cause the Fund’s NAV per share to fall. The frequency and magnitude of such changes cannot be predicted.

The secondary market in which these investments are traded is generally less liquid than the market for higher-grade debt. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield Senior Loan, and could adversely affect the NAV of the Fund’s shares. At times of less liquidity, it may be more difficult to value high yield Senior Loans because this valuation may require more research, and elements of judgment may play a greater role in the valuation since there is less reliable, objective data available. Investments in Senior Loans and other securities may result in greater NAV fluctuation than if the Fund did not make such investments. See “Taxation” below for a discussion of special tax consequences associated with any investment by the Fund in below investment grade securities.

As with any debt security, Senior Loans are generally subject to the risk of price declines due to increases in interest rates, particularly long-term rates. Senior loans are also subject to the risk that, as interest rates rise, the cost of borrowing increases, which may increase the risk of default. In addition, the interest rates of floating rate loans typically only adjust to changes in short-term interest rates; long-term interest rates can vary dramatically from short-term interest rates. Therefore, Senior Loans may not mitigate price declines in a rising long-term interest rate environment. Declines in interest rates may increase prepayments of debt obligations and require the Fund to invest assets at lower yields. No active trading market may exist for certain Senior Loans, which may impair the ability of the Fund to realize full value in the event of the need to liquidate such assets. Adverse market conditions may impair the liquidity of some actively traded Senior Loans.

Although Senior Loans in which the Fund will invest will often be secured by collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower’s obligation in the event of a default or that such collateral could be readily liquidated. In the event of bankruptcy of a borrower, the Fund could experience delays or limitations in its ability to realize the benefits of any collateral securing a Senior Loan. The Fund may also invest in Senior Loans that are not secured.

In addition to the risks typically associated with debt securities and loans generally, 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.

Short Sales Risk: Short sales by the Fund that are not made “against-the-box” (that is when the Fund have an offsetting long position in the asset that is selling short) involve unlimited loss potential since the market price of securities

25

sold short may continuously increase. When the Fund engages in a short sale on a security, it must borrow the security sold short and deliver it to the counterparty. The Fund will ordinarily have to pay a fee or premium to borrow particular securities and be obligated to repay the lender of the security any dividends or interest that accrue on the security during the period of the loan. The amount of any gain from a short sale will be decreased, and the amount of any loss increased, by the amount of the premium, dividends, interest or expenses the Fund pays in connection with the short sale. Short selling allows the Fund to profit from declines in market prices to the extent such decline exceeds the transaction costs and the costs of borrowing the securities. However, since the borrowed securities must be replaced by purchases at market prices in order to close out the short position, any appreciation in the price of the borrowed securities would result in a loss. Purchasing securities to close out the short position can itself cause the price of the securities to rise further, thereby exacerbating the loss. The Fund may mitigate such losses by replacing the securities sold short before the market price has increased significantly. Under adverse market conditions, the Fund might have difficulty purchasing securities to meet their short sale delivery obligations, and might have to sell portfolio securities to raise the capital necessary to meet their short sale obligations at a time when fundamental investment considerations would not favor such sales. See “Taxation” below for special tax considerations associated with engaging in short sales.

Swaps Risk: The use of swaps is a highly specialized activity which involves investment techniques, risk analyses and tax planning different from those associated with ordinary portfolio securities transactions. These transactions can result in sizeable realized and unrealized capital gains and losses relative to the gains and losses from the Fund’s direct investments in securities.

Transactions in swaps can involve greater risks than if the Fund had invested in the reference assets directly since, in addition to general market risks, swaps may be leveraged and are also subject to illiquidity risk, counterparty risk, credit risk and pricing risk. However, certain risks may be reduced (but not eliminated) if the Fund invests in cleared swaps. Regulators also may impose limits on an entity’s or group of entities’ positions in certain swaps. Because bilateral swap agreements are two party contracts and because they may have terms of greater than seven days, these swaps may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap in the event of the default or bankruptcy of a swap counterparty. Many swaps are complex and valued subjectively. Swaps and other derivatives may also be subject to pricing or “basis” risk, which exists when the price of a particular derivative diverges from the price of corresponding cash market instruments. Under certain market conditions it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity. If a swap transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

The value of swaps can be very volatile, and a variance in the degree of volatility or in the direction of securities prices from the Adviser’s expectations may produce significant losses in the Fund’s investments in swaps. In addition, a perfect correlation between a swap and a reference asset may be impossible to achieve. As a result, the Adviser’s use of swaps may not be effective in fulfilling the Adviser’s investment strategies and may contribute to losses that would not have been incurred otherwise.

Disclosure of Portfolio Holdings

The Fund has adopted policies and procedures to protect its portfolio information and to prevent the misuse of that information by a third party. A description of the Fund’s policies and procedures relating to the disclosure of portfolio holdings is available in the Fund’s SAI on the Fund’s website (www.highlandfunds.com).
