Summary Prospectus by Investment Company - Form 497K

•

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

•

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

•

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

•

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

•

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

•

Sovereign debt risk - Investments issued by a governmental entity are subject to the risk that the governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt due to, among other things, cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity's debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay its debt, request additional loans or otherwise restructure its debt. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt may be collected.

•

Concentration risk - The Fund may concentrate its investments in certain securities. To the extent that the Fund focuses on particular countries, regions, industries, sectors, issuers, types of investment or limited number of securities from time to time, the Fund may be subject to greater risks of adverse economic, business or political developments in the area of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

•

Emerging markets and less developed countries risk - Emerging market and less developed countries generally are located in Asia, the Middle East, Eastern Europe, Central and South America and Africa.Investments in, or exposure to, securities that are tied economically to emerging market and less developed countries are subject to all of the risks of investments in, or exposure to, foreign securities, generally to a greater extent than in developed markets, among other risks. Investments in securities that are tied economically to emerging markets involve greater risk from economic and political systems that typically are less developed, and likely to be less stable, than those in more advanced countries. The Fund also will be subject to the risk of adverse foreign currency rate fluctuations. Emerging market and less developed countries may also have economies that are predominantly based on only a few industries or dependent on revenues from particular commodities. The risks of nationalization, expropriation or other confiscation of assets of non-U.S. issuers is also greater in emerging and less developed countries. As a result of these risks, investments in securities tied economically to emerging markets tend to be more volatile than investments in securities of developed countries.

•

Currency risk - Investments in foreign currencies, securities that trade in or receive revenues in foreign currencies, or derivatives that provide exposure to foreign currencies are subject to the risk that those currencies may decline in value or, in the case of hedging positions, that the currency may decline in value relative to the currency being hedged. Currency exchange rates can be volatile and may be affected by a number of factors, such as the general economics of a country, the actions (or inaction) of U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.

•

Currency management strategies risk - Currency management strategies may substantially change the Fund's exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the investment manager expects. In addition, currency management strategies, to the extent that they reduce the Fund's exposure to currency risks, may also reduce the Fund's ability to benefit from favorable changes in currency exchange rates. Using currency management strategies for purposes other than hedging further increases the Fund's exposure to foreign investment losses. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns.

•

Foreign exchange and currency derivatives trading risk - The Fund intends to actively trade in spot and forward currency positions and related currency derivatives in order to increase the value of the Fund. The trading of foreign currencies directly generates risks separate from those associated with inactive or indirect exposures to non-U.S. dollar denominated instruments and currency derivative instruments. Specifically, the Fund may directly take a loss from the buying and selling of currencies without any related exposure to non-U.S. dollar-denominated assets.

•

Foreign securities risk - Investments in, or exposure to, foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values, possible imposition of foreign withholding or other taxes on income payable on the securities, as well as adverse political, social and economic developments, such as political upheaval, acts of terrorism, financial troubles, sanctions or the threat of new or modified sanctions, or natural disasters. Many foreign securities markets, especially those in emerging market countries, are less stable, smaller, less liquid, and less regulated than U.S. securities markets, and the costs of trading in those markets is often higher than in U.S. securities markets. There may also be less publicly available information about issuers of foreign securities compared to issuers of U.S. securities. In addition, the economies of certain foreign markets may not compare favorably with the economy of the United States with respect to issues such as growth of gross national product, reinvestment of capital, resources and balance of payments position.

•

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

•

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

•

Market direction risk - Since the Fund will typically hold both long and short positions, an investment in the Fund will involve market risks associated with different types of investment decisions than those made for a typical "long only" fund. The Fund's results could suffer when there is a general market advance and the Fund holds significant "short" positions, or when there is a general market decline and the Fund holds significant "long" positions. The markets may have considerable volatility from day to day and even in intra-day trading.

•

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

•

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

•

Allocation risk - The Fund's ability to achieve its investment objective depends upon the investment manager's analysis of such factors as macroeconomic trends, outlooks for various industries and asset class valuations, and its ability to select an appropriate mix of asset classes based on its analysis of such factors. TheFund is subject to the risk of changes in market, investment, and economic conditions in the selection and percentages of allocations.

•

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

•

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

•

Banking industry investment risk - Investment in securities issued by banks may be affected by factors influencing the health and performance of the banking industry. These factors may include, among others, economic trends, industry competition and governmental actions, as well as factors affecting the financial stability of borrowers. Bank securities typically are not insured by the U.S. government, foreign governments, or their agencies. Bank securities that do not represent deposits have lower priority in the bank's capital structure than those securities comprised of deposits. This lower priority means that, in the event of insolvency of the bank that issued the security, the security could become worth less than the Fund paid for it.

•

Commercial mortgage-backed securities risk - Commercial mortgage-backed securities include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities.

•

Corporate loan, sovereign entity loan, and bank loan risk - Commercial banks, sovereign entities, and other financial institutions or institutional investors make corporate loans to companies or sovereign entities that need capital to grow, restructure, or for infrastructure projects. These instruments are commonly referred to as "loans" or "bank loans." Borrowers generally pay interest on corporate loans at "floating" rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate ("SOFR") or the prime rates of U.S. banks. As a result, the value of such loan investments is generally less exposed to the adverse effects of interest rate fluctuations than investments that pay a fixed rate of interest. However, the market for certain loans may not be sufficiently liquid, and the Fund may have difficulty selling them. It may take longer than seven days for transactions in loans to settle. As a result, sale proceeds related to the sale of loans may not be available to make additional investments until a substantial period after the sale of the loans. Certain loans may be classified as "illiquid" securities. Additionally, because a loan may not be considered a security, the Fund may not be afforded the same legal protections afforded securities under federal securities laws. Thus, the Fund generally must rely on contractual provisions in the loan agreement and common-law fraud protections under applicable state law.

•

Debt securities ratings risk- The use of credit ratings in evaluating debt securities can involve certain risks, including the risk that the credit rating may not reflect the issuer's current financial condition or events since the security was last rated by a rating agency. Credit ratings may be influenced by conflicts of interest or based on historical data that no longer apply or are accurate.

•

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

•

European investment risk - Investing in Europe involves many of the same risks as investing in foreign securities. In addition, since Europe includes both developed and emerging markets, investments by the Fund will be subject to the risks associated with investments in such markets. Performance is expected to be closely tied to social, political, and economic conditions within Europe and to be more volatile than the performance of more geographically diversified funds. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns in, or rising government debt levels of, several European countries as well as acts of war in the region. These events may spread to other countries in Europe and may affect the value and liquidity of certain of the Fund's investments. For example, in June 2016, the United Kingdom approved a referendum to leave the European Union (commonly known as "Brexit"). The United Kingdom left the European Union on January 31, 2020 with an eleven-month transition period ending December 31, 2020, during which the United Kingdom and the European Union agreed to a Trade and Cooperation Agreement governing the future relationship between the United Kingdom and the European Union from January 1, 2021. On January 1, 2021, European Union laws ceased to apply in the United Kingdom. Many European Union laws were transposed into English law and these transposed laws continue to apply until such time that they are repealed, replaced or amended. The United Kingdom government has enacted legislation that will repeal, replace or otherwise make substantial amendments to the European Union laws that currently apply in the United Kingdom. It is impossible to predict the consequences of these amendments on the Fund and its investments. Brexit may also create uncertainty around trade within Europe, the possibility of capital outflows from the United Kingdom, devaluation of the pound sterling, the cost of higher corporate bond spreads, and the risk that all the above could negatively impact business and consumer spending as well as foreign direct investment.

•

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

•

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

•

Government regulatory risk - Certain industries or sectors, including, but not limited to, real estate, financial services, utilities, oil and natural gas exploration and production, and health care are subject to increased regulatory requirements. There can be no guarantee that companies in which the Fund invests will meet all applicable regulatory requirements. Certain companies could incur substantial fines and penalties for failing to meet government regulatory requirements. These requirements may also result in additional compliance expenses and costs. Such increased regulatory compliance costs could hurt a company's performance.

•

Hedging instruments risk- The Fund may attempt, from time to time, to hedge (protect) against currency risks, largely using forward foreign currency exchange contracts, where available and when, in the Sub-Adviser's opinion, it would be advantageous to the Fund. A forward foreign currency exchange contract is an agreement to buy or sell a specific currency at a future date and at a price set at the time of the contract. Forward foreign currency exchange contracts may reduce the risk of loss from a change in value of a currency, but they also limit any potential gains and do not protect against fluctuations in the value of the underlying position. For example, during periods when the U.S. dollar weakens in relation to a foreign currency, the Fund's use of a currency hedging program will result in lower returns than if no currency hedging programs were in effect. Forward foreign currency exchange contracts and put options are considered derivative investments, because their value and performance depend, at least in part, on the value and performance of an underlying asset. The Fund may also use futures, swaps, and other derivative instruments to hedge risk. The Fund's investment in derivatives may involve a small investment relative to the amount of risk assumed. To the extent the Fund enters into these transactions, its success will depend on the Sub-Adviser's ability to predict market movements, and their use may have the opposite effect of that intended. Risks include potential loss due to the imposition of controls by a government on the exchange of foreign currencies, the loss of any premium paid to enter into the transaction, delivery failure, default by any other party, or inability to close out a position because the trading market becomes illiquid. In addition, for certain reasons, the Fund may not seek to establish a perfect correlation between such hedging instruments and the portfolio instruments being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. It is not possible to hedge fully or perfectly against any risk.

•

Income risk - The Fund is subject to the risk that the income generated from the Fund's investments may decline in the event of falling interest rates. Income risk may be high if the Fund's income is predominantly based on short-term interest rates, which can fluctuate significantly over short periods. The Fund's distributions to shareholders may decline when interest rates fall.

•

Latin America concentration risk - The Fund's performance is expected to be closely tied to social, political and economic conditions within Latin American countries. Funds that concentrate in specific countries and regions, such as Latin America, tend to have more performance volatility than the performance of more geographically diversified funds. Investment primarily in equity and equity-related securities in Latin America will expose the Fund specifically to their market, currency and other risks, including volatility and structural risks. Stable economic growth may be hampered by a number of factors, including, burdensome regulatory requirements, inflation, poor allocation of resources and the reinvestment of capital, government price controls and capital restrictions, and social instability with a corresponding effect on securities holdings and volatility.

•

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

•

Russia investment risk -During periods when sanctions are in place, such as the ongoing Russia/Ukraine war, there are risks related to holding positions located in or with ties to Russia. This may include, but is not limited to, the inability to dispose of securities in that country, the inability to settle securities transactions in that country, and the inability to repatriate currency from that country. Investments in sanctioned countries may be volatile, and the Fund and its pricing agent may have difficulty valuing such sanctioned securities. Absent sanctions prohibiting these investments, the Fund may invest a portion of its assets in securities issued by companies located in Russia. Because of the underdeveloped state of Russia's banking system and securities markets, settlement, clearing and registration of securities transactions are subject to significant risks. With the implementation of the National Settlement Depository ("NSD") in Russia as a recognized central securities depository, title to Russian equity securities is now based on the records of the NSD and not the registrars. Although the implementation of the NSD is generally expected to decrease the risk of loss in connection with recording and transferring title to securities, issues resulting in loss still might occur. In addition, issuers and registrars are still prominent in the validation and approval of documentation requirements for corporate action processing in Russia. Because the documentation requirements and approval criteria vary between registrars and/or issuers, there remain unclear and inconsistent market standards in the Russian market with respect to the completion and submission of corporate action elections. To the extent that the Fund suffers a loss relating to title or corporate actions relating to its portfolio securities, it may be difficult for the Fund to enforce its rights or otherwise remedy the loss.

•

Speculative exposure risk - If the Fund invests in a derivative instrument (or engages in a similarly speculative practice) not for the purpose of hedging, the Fund is directly exposed to the risks associated with an investment in that derivative. Gains or losses from speculative positions in a derivative may be much greater than the derivative's original cost and, in certain instances, potential losses may be unlimited.

•

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

•

China risk - The Chinese economy is generally considered an emerging market and can be significantly affected by economic and political conditions and policy in China and surrounding Asian countries. A relatively small number of Chinese companies represents a large portion of China's total market and thus may be more sensitive to adverse political or economic circumstances and market movements. The economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others. Under China's political and economic system, the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership. In addition, expropriation, including nationalization, repatriation of capital, confiscatory taxation, political, economic or social instability or other developments could adversely affect and significantly diminish the values of the Chinese companies in which the Fund invests. The Chinese securities markets are subject to more frequent trading halts and low trading volume, resulting in substantially less liquidity and greater price volatility. These and other factors could have a negative impact on the Fund's performance and increase the volatility of an investment in the Fund.

•

Equity securities risk - Common and preferred stocks represent equity ownership in a company. Stock markets are volatile, and equity securities generally have greater price volatility than fixed-income securities. The price of equity or equity-related securities will fluctuate and can decline and reduce the value of a portfolio investing in equity or equity-related securities. The value of equity or equity-related securities purchased or held by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry. In addition, they may decline due to general market conditions that are 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 generally adverse investor sentiment.

•

Convertible securities risk - Convertible securities have investment characteristics of both equity and debt securities. Investments in convertible securities may be subject to market risk, credit and counterparty risk, interest rate risk and other risks associated with investments in equity and debt securities, depending on the price of the underlying security and conversion price. While equity securities may offer the potential for greater long-term growth than most debt securities, they generally have higher volatility. The value of convertible and debt securities may fall when interest rates rise. Securities with longer durations tend to be more sensitive to changes in interest rates, generally making them more volatile than securities with shorter durations. Due to their hybrid nature, convertible securities are typically more sensitive to changes in interest rates than the underlying common stock, but less sensitive than a fixed rate corporate bond.

•

Contingent convertible securities risk - Contingent convertible securities ("CoCos") are a form of hybrid fixed-income instrument. They are subordinated instruments that are designed to behave like bonds or preferred equity in times of economic health for the issuer, yet absorb losses when a pre-determined "trigger event" affecting the issuer occurs. CoCos are either convertible into equity at a predetermined share price or written down if a pre-specified trigger event occurs (in certain circumstances, the value may be written down to zero). Trigger events vary by individual security and are defined by the documents governing the contingent convertible security. The triggers are generally linked to regulatory capital thresholds or regulatory actions calling into question the issuing banking institution's continued viability as a going-concern. CoCos' unique equity conversion or principal write-down features are tailored to the issuing banking institution and its regulatory requirements. If the CoCos are converted into the issuer's underlying equity securities following a conversion event (i.e., a "trigger"), each holder will be subordinated due to their conversion from being the holder of a debt instrument to being the holder of an equity instrument.

•

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

•

Investment in money market funds risk - Although a money market fund is designed to be a relatively low risk investment, it is not free of risk. An investment in a money market fund is not insured or guaranteed by a Federal Deposit Insurance Corporation or any other government agency. Although such funds seek to maintain a net asset value of $1.00 per share, it is possible to lose money by investing in a money market fund.

•

Non-diversification risk - The Fund is non-diversified, as defined by the 1940 Act, and as such may invest in the securities of a limited number of issuers and may invest a greater percentage of its assets in a particular issuer. Therefore, a decline in the market price of a particular security held by the Fund may affect the Fund's performance more than if the Fund were a diversified investment company.
