#### SUMMARY INFORMATION ABOUT THE FUND

#### Polar Capital Emerging Market ex-China Stars Fund
(the "Fund")

**Ticker:** POLCX

#### Investment Objective
The Fund's investment objective is to achieve long term capital growth.

#### Fees and Expenses
This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table or example below.

**Shareholder Fees** (Fees paid directly from your investment)

---

| |
|:---|
|  Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price) |
|  Maximum Deferred Sales Charge (Load) (as a percentage of amount redeemed) |
|  Redemption Fee (as a percentage of amount redeemed) |

---

**Annual Fund Operating Expenses** (Expenses that you pay each year as a percentage of the value of your investment)

---

| | |
|:---|:---|
|  Management Fee | 1.00% |
|  Distribution (Rule 12b-1) Fees |  |
|  Other Expenses | 16.88% |
|  Total Annual Fund Operating Expenses | 17.88% |
|  Fee Waivers and Expense Reimbursements<sup>(1)</sup> | (16.88%) |
|  **Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements** | 1.00% |

---

<sup>(1)</sup> Polar Capital LLP (the "Adviser"), the Fund's investment adviser, has contractually agreed to waive Management Fees and to reimburse Other Expenses to the extent Total Annual Fund Operating Expenses (exclusive of brokerage costs, interest, taxes, dividends, litigation and indemnification expenses, and expenses associated with the investments in underlying investment companies) exceed 1.00% of the average daily net assets of the Fund through November 8, 2024. Amounts waived or reimbursed in a particular contractual period may be recouped by the Adviser for 36 months following the waiver or reimbursement however, such recoupment will be limited to the lesser of any expense limitation in place at the time of recoupment or the expense limitation in place at the time of waiver or reimbursement. This agreement may only be terminated earlier by the Fund's Board of Trustees (the "Board") or upon termination of the Investment Management Agreement.

#### Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless of whether or not you redeem your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-year period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | |
|:---|:---|
| **One Year** | **Three Years** |
| $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;102 | $2018 |

---

------

#### Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance.

Because the Fund has not yet commenced operations as of the date of this prospectus, the Fund's portfolio turnover rate for the most recent fiscal year is not available.

#### Principal Investment Strategies
The Fund will seek to achieve its investment objective by primarily investing in a portfolio of equity securities and equity related securities of, or relating to, companies which are domiciled, or exercise the predominant part of their economic activity, in developing capital markets ("Emerging Markets").

Under normal market conditions, the Fund invests at least 80% of its net assets for investment purposes in equity securities and other equity-related investments of issuers located in Emerging Markets countries, excluding China. The Fund considers an issuer to be located in an Emerging Markets country if at least 50% of the issuer's assets, gross revenues or profits during the most recent fiscal year represents assets or activities located in such countries. Emerging Markets refers to any country represented in the MSCI Emerging Markets ex China Index.

The Fund will not invest in any company incorporated in mainland China, or that has mainland China as its core country of risk (as determined by the Adviser). The Fund may invest up to 20% of its assets in non-Chinese companies that, for any reason, are listed in Hong Kong or that derive a meaningful portion of their assets, gross revenues or profits from China. The Fund may also have limited exposure to the Chinese economy, as a consequence of the indirect exposure that companies in other Emerging Markets countries have to China.

The securities in which the Fund will invest will include shares, equities, equity warrants, preferred shares, shares in collective investment schemes with investment policies that are consistent with the Fund's investment objective (including European Undertakings for the Collective Investment in Transferable Securities or Alternative Investment Funds, shares of U.S. mutual funds, or other exchange traded funds) and securities convertible into shares.

The Fund may invest in global, American and European depository receipts for the purpose of gaining exposure to underlying equity securities.

The Fund may utilize various derivative instruments and related strategies to gain exposure to one or more issuers or other assets. The Fund may utilize derivatives of all types and may invest in futures, forwards, options, contracts for difference, swaps and securities with embedded derivatives or elements of derivative exposure including, but not limited to, equity warrants and structured notes, such as P-Notes (which will not be leveraged).

The Fund expects to primarily use derivatives for hedging or efficient portfolio management purposes or to reduce portfolio risk. The Fund may also use them to increase the Fund's investment exposure beyond that which it could achieve by investing directly in more conventional securities.

Securities with embedded derivatives or elements of derivative exposure, such as equity warrants and structured notes such as P-Notes (which will not be leveraged) may be used to gain exposure to underlying equity or equity related securities as a more efficient and cheaper alternative to direct investment in that security.

The Fund observes a policy to normally invest at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities and other equity-related investments in Emerging Markets, excluding China. The Fund's investments in derivatives and other synthetic instruments (such as Participatory Notes and American Depository Receipts) that have economic characteristics similar to these investments will be counted toward satisfaction of the Fund's 80% investment policy.

In evaluating investments for the Fund, the Adviser expects to take into account environmental, social and/or governance ("ESG") factors. The Adviser may give various ESG factors equal consideration or may focus on one or more of those factors as it considers appropriate. ESG Factors will only be one consideration in the Adviser's evaluation of any potential investment, and the effect of ESG factors on the Adviser's decision whether to invest in any case will vary depending on the judgement of the Adviser.

#### Principal Risks
**It is possible to lose money on an investment in the Fund.** The Fund will be affected by the investment decisions, techniques and risk analyses of the Fund's Adviser and there is no guarantee that the Fund will achieve its investment objective. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds. Each risk summarized below is considered to be a "principal risk" of investing in the Fund, regardless of the order in which it appears.

**Risks Associated with Investing in Equities.** The Fund may invest in equity and equity-related securities traded on recognized stock exchanges and over-the-counter markets. Equity securities will be subject to risks associated with such investments, including fluctuations in market prices, adverse issuer or market information and the fact that equity and equity-related interests are subordinate in the right of payment to other corporate securities, including debt securities. The value of these securities varies with the performance of the respective issuers and movements in the equity markets generally. As a result, the Fund may suffer losses if it invests in equity securities of issuers where performance falls below market expectations or if equity markets in general decline or the Fund has not hedged against such a general decline. Futures and options on futures on equity securities and indices are subject to all the foregoing risks, in addition to the risks particularly associated with futures and derivative contracts.

**ESG Investing Risk.** The Fund's consideration of environmental, social and/or governance factors as part of its investment process may cause it to make different investments than funds that have a similar investment universe and/or investment style but that do not incorporate such factors in their strategy or investment processes. Additionally, the Fund may forgo opportunities to buy certain securities when it might otherwise be advantageous to do so, or sell securities when it might be otherwise disadvantageous for it to do so. Incorporating ESG factors into investment decision making is qualitative and subjective by nature, and there is no guarantee that the factors considered by the Adviser or any judgment exercised by the Adviser will reflect the beliefs or values of any particular investor. Socially responsible norms differ by region and industry, and a company's ESG practices or the Adviser's assessment of a company's ESG practices may change over time.

**Risks Associated with Investing in Emerging Markets.** The Fund's investments in non-U.S. issuers in developing or emerging market countries may involve increased exposure to changes in economic, social and political factors as compared to investments in more developed countries. The economies of most emerging market countries are in the early stage of capital market development and may be dependent on relatively fewer industries. As a result, their economic systems are still evolving. Their legal and political systems may also be less stable than those in developed economies. Securities markets in these countries can also be smaller, and there may be increased settlement risks. The Public Company Accounting Oversight Board, which regulates auditors of U.S. companies, is unable to inspect audit work papers in certain foreign countries. Investors in emerging markets often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the U.S. Securities and Exchange Commission, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited. Emerging market countries often suffer from currency devaluation and higher rates of inflation. Due to these risks, securities issued in developing or emerging countries may be more volatile, less liquid, and harder to value than securities issued in more developed countries.

**Derivatives Risk.** The use of derivatives involves the risk that their value may not move as expected relative to the value of the relevant underlying assets, rates, or indices. Derivatives also present other risks, including market risk, liquidity risk, and counterparty risk.

**Market Risk.** The value of securities and instruments owned by the Fund may rise and fall, sometimes rapidly or unpredictably, due to factors affecting securities markets generally or particular industries or geographic areas.

**Liquidity Risk.** In some circumstances, investments may be relatively illiquid making it difficult to acquire or dispose of them at the prices quoted on the various exchanges. Accordingly, the Fund's ability to respond to market movements may be impaired and the Fund may experience adverse price movements upon liquidation of its investments. Settlement of transactions may be subject to delay and administrative uncertainties.

**Counterparty and Third-Party Risk.** Transactions involving a counterparty (including a clearing member or clearing house through which the Fund holds a derivative position) to a derivative contract, repurchase agreement, reverse repurchase agreement, or other financial instrument, or a third party responsible for servicing the instrument, are subject to the credit risk of the counterparty or third party, and to the counterparty's or third party's ability to perform in accordance with the terms of the transaction.

------

**Large Investor Risk.** Ownership of shares of the Fund may be concentrated in one or a few large investors. Such investors may redeem shares in large quantities or on a frequent basis. Redemptions by a large investor may affect the performance of the Fund, may increase realized capital gains, may accelerate the realization of taxable income or gains for shareholders and may increase transaction costs. These transactions potentially limit the use of any capital loss carryforwards and certain other losses to offset future realized capital gains (if any). Such transactions may also increase the Fund's expenses. In addition, the Fund may be delayed in investing new cash after a large shareholder purchase, and under such circumstances may be required to maintain a larger cash position than it ordinarily would.

**Management Risk.** The Fund is subject to management risk as an actively managed investment portfolio. The portfolio managers will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results. The portfolio managers' opinion about the intrinsic worth or creditworthiness of a company or security may be incorrect, the portfolio managers may not make timely purchases or sales of securities for the Fund, the Fund's investment objective may not be achieved, or the market may continue to undervalue the Fund's securities. In addition, the Fund may not be able to quickly dispose of certain securities holdings. Moreover, there can be no assurance that the personnel of the Adviser will continue to be associated with the Adviser for any length of time, and the loss of services of one or more key employees of the Adviser, including the portfolio managers, could have an adverse impact on the Fund's ability to achieve its investment objective. Certain securities or other instruments in which the Fund seeks to invest may not be available in the quantities desired. In such circumstances, the portfolio managers may determine to purchase other securities or instruments as substitutes. Such substitute securities or instruments may not perform as intended, which could result in losses to the Fund.

**Risks Associated with Non-Diversification**. The Fund is non-diversified, which generally means that it may invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund's value will likely be more volatile than the value of a more diversified fund. In addition, due to its relatively low number of holdings, the Fund will be more susceptible to company-specific events and risks impacting the particular securities held by the Fund than a fund with a greater number of holdings.

**Risks Associated with Changes to Non-U.S. Tax Laws.** Fund investors should also consider the possibility of changes to non-U.S. tax laws and regulations (including potential retroactive changes) which may adversely affect certain investments made by the Fund, including as a result of the Action Plan on Base Erosion and Profit Shifting ("BEPS"), which has been developed with the aim of securing revenue by realigning taxation with economic activities and value creation by creating a single set of consensus based international tax rules. As part of the BEPS project, it is anticipated that new rules dealing with the operation of double tax treaties, the definition of permanent establishments, interest deductibility and how hybrid instruments and hybrid entities are taxed will have been and continue to be introduced. To facilitate implementation of the BEPS project, the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting has modified, and continues to modify, a wide range of double tax treaty provisions. In addition, the European Council's Anti-Tax Avoidance Directive addresses many of the same issues. These initiatives could adversely affect the Fund or certain or all Fund investors, including but not limited to causing additional reporting and disclosure obligations for Fund investors. In addition, there may be changes in the tax laws or interpretations of tax laws in jurisdictions in which the Fund, and/or any entity owned directly or indirectly by the Fund, are established, are operating, are managed, are advised, are promoted or are investing, or in which Fund investors are resident, that are adverse to the Fund, and/or any entities owned directly or indirectly by the Fund and/or the Fund investors. Changes to taxation treaties or interpretations of taxation treaties between one or more such jurisdictions and the countries through which the Fund and/or any entities owned directly or indirectly by the Fund hold investments or in which a Fund investor is resident or the introduction of, or change to, EU Directives (including but not limited to the Anti-Tax Avoidance Directives) may adversely affect the ability of the Fund and/or any entities owned directly or indirectly by the Fund to efficiently realize income or capital gains. Consequently, it is possible that the Fund and/or any entities owned directly or indirectly by the Fund may face unfavorable tax treatment in such jurisdictions that may materially adversely affect the value of the investments held by the Fund and/ or any entities owned directly or indirectly by the Fund or the feasibility of making investments in certain countries.

**Participatory Notes Risk.** An investment in participatory notes is subject to market risk. The performance results of participatory notes may not exactly replicate the performance of the underlying securities. An investment in participatory notes is also subject to counterparty risk, relating to the non-U.S. bank or broker-dealer that issues the participatory notes, and may be subject to liquidity risk.

**Currency Risk.** The currencies in which investments are denominated may be unstable, may be subject to significant depreciation and may not be freely convertible.

------

**Custody Risk.** In a limited number of markets, particularly in emerging economies, where a no failed trade policy is standard market practice, assets may be assigned, transferred, exchanged or delivered without the prior approval of the Depositary or its agent. Once a sale order is placed in relation to assets of the Fund, by virtue of the operation of the settlement system within those markets, those assets will automatically move from custody of the Depositary without the need for the prior approval of the Depositary. Where this occurs the consideration for those assets is remitted to the entity releasing the assets.

**Cyber Security Risk.** The Fund and its service providers are susceptible to operational and information security and related risks of cyber security incidents. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber security attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through "hacking" or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data or causing operational disruption. Cyber-attacks also may be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make services unavailable to intended users). Cyber security incidents affecting the Fund, Adviser, Custodian or Administrator or other service providers such as financial intermediaries have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, including by interference with the Fund's ability to calculate its NAV; impediments to trading for the Fund's portfolio; the inability of Shareholders to transact business with the Fund; violations of applicable privacy, data security or other laws; regulatory fines and penalties; reputational damage; reimbursement or other compensation or remediation costs; legal fees; or additional compliance costs. Similar adverse consequences could result from cyber security incidents affecting issuers of securities in which the Fund invests, counterparties with which the Fund engages in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies and other financial institutions and other parties. While information risk management systems and business continuity plans have been developed which are designed to reduce the risks associated with cyber security, there are inherent limitations in any cyber security risk management systems or business continuity plans, including the possibility that certain risks have not been identified.

Because of these and other risks, you could lose money by investing in the Fund.

**An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.**

#### Payments to Broker-Dealers and Other Financial Intermediaries

These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

The investment objective of the Fund is not fundamental and may be changed at any time by the Board of Trustees without shareholder approval. The Fund has adopted an 80% investment policy under Rule 35d-1 under the Investment Company Act of 1940, as amended (the "1940 Act") and will not change such policy as it is stated in the Fund's Fund Summary unless it provides shareholders with the notice required by Rule 35d-1, as it may be amended or interpreted by the SEC from time to time.

Investing in the Fund involves risk and there is no guarantee that the Fund will achieve its objective. The portfolio managers' judgments about the markets, the economy, or companies may not anticipate actual market movements, economic conditions, or company performance, and these judgments may affect the return on your investment.

This section provides additional information about the principal investment strategies utilized by the Fund. Pending investment in securities and other investments that meet the Fund's investment objective and policies, the proceeds of the offering of shares of the Fund, including from large subscriptions, may be invested in high quality, short-term securities, including liquidity and cash management funds, or may remain un-invested temporarily, potentially limiting the Fund's total return and its ability to achieve its investment objective.

#### Investment Process for the Fund
The portfolio managers' investment approach focuses primarily on fundamental bottom-up stock selection with top-down macro-economic research and analysis. The portfolio managers have identified three primary elements of their bottom-up analysis (growth areas, economic value add creation factors, and economic value add valuation) and three primary elements of their sustainability delta analysis (impact on progress, material ESG issues, and business ethics), each of which may be graphically represented in the points of a star. The portfolio managers may give various elements equal consideration or may give greater weight to one or more elements as they consider appropriate.

**Top down analysis.** The portfolio managers seek to identify growth opportunities by looking at global growth expectations, demand drivers, supply drivers (including those which impact changes in supply), macroeconomic trends (such as social demographic trends, monetary and fiscal policy, government models, and competitiveness) and factors impacting company valuations to establish a dynamic understanding of the economic backdrop to the investment universe.

**Bottom up analysis.** The portfolio managers' research efforts are directed towards detailed analysis of a company's specific strategic position and opportunities within its industry with a view to establishing its potential for future Economic Value Added ("EVA"). EVA is a measure of a company's financial performance based on the residual wealth calculated by deducting its cost of capital from its operating profit, adjusted for taxes on a cash basis. EVA can also be referred to as economic profit as it attempts to capture the true economic profit of a company. The portfolio managers look to identify companies that, in their view, have the capability to generate a high, and growing, level of EVA in the future (identified over the medium to long term investment horizon).

Having assessed a company's opportunity for growth, its competitive position and its potential to create EVA, the portfolio managers uses a proprietary valuation model to identify its expected level of future EVA creation and its expected market value in relation to its current price.

------

**Sustainability.** In addition to the fundamental financial and qualitative analysis described above, the portfolio managers also evaluate risks and opportunities from an Environmental, Societal and Governance ("ESG") perspective.

The portfolio managers consider three specific ESG areas of a company's profile: the company's "Impact on Progress" to sustainable economic development, the company's exposure to "Material ESG Issues" and the company's "Business Ethics." Taken together, the scores on these areas are used to analyze both the current position and expected future direction of a company's ESG profile.

*Impact on Progress:* The portfolio managers examine how a company impacts economic development by driving economic growth and productivity and/or through the company's use of natural resources. The Adviser also evaluates the company's impact on human capital development through its longer-term strategic focus and capital allocation.

*Material ESG Issues:* The portfolio managers analyze how a company manages its ESG exposures deemed material by the portfolio managers. For the 'Environmental' and 'Social' categories, the portfolio manager evaluates factors specific to the company's industry and for the 'Governance' category, the Adviser evaluates a company against industry-agnostic system factors.

*Business Ethics:* The portfolio managers analyze whether they believe a company acts with integrity, competes fairly and is open and honest with its stakeholders.

*Sustainability Delta:* By combining the company's scores in each of the three areas identified above, the portfolio managers give the company a "Sustainability Delta" rating for both its current level of sustainability and its expected future sustainability direction. The portfolio managers define an "improving company" as one where the company's future direction Sustainability Delta score is higher than its current level Sustainability Delta Score. The portfolio managers integrate the Sustainability Delta scores into its financial valuation models to understand how the portfolio managers believe company's ESG profile impacts its ability to deliver attractive profitability over the long term. The portfolio managers monitor Sustainability Delta scores for all companies held in the portfolio on an ongoing basis (as well as prior to investment) and will update the Sustainability Delta scores on an event-driven basis. If an investee company's Sustainability Delta profile significantly deteriorates during the holding period, the portfolio managers will generally engage with the company in the first instance to better understand the materiality of the related risks and management's strategic direction.

*Corporate Governance:* The portfolio managers view stakeholder alignment as an important part of its investment analysis. The management of a company's corporate governance is assessed in detail with reference to four key areas: management incentives, board effectiveness, ownership and control, and accounting practices.

*Exclusions:* The portfolio managers adhere to the Norges Bank exclusion list (which can be found at https://www.nbim.no/en/the-fund/responsible-investment/exclusion-of-companies), which comprises a list of companies which are, or have been involved, with severe environmental or social controversies. All companies on this list are entered into control systems which prevent the Fund from making investments in companies on the list at time of investment. The exclusion list is updated on an ongoing basis. In addition, the portfolio managers' fundamental process may indirectly exclude companies that have a negative impact on long-term societal progress. This is considered in the evaluation of the company's "Impact on Progress" and "Business Ethics." Further, the portfolio managers utilize sector-based exclusions to avoid companies involved in activities deemed by the portfolio managers to be unacceptable or controversial from an environmental, societal and/or governance perspective. These include exclusions on all companies that derive more than five percent of their revenue from alcohol, gambling, tobacco, adult entertainment, and armaments. The Fund's fossil fuel exclusion stipulates zero tolerance on any investment into coal operations and does not allow investment in companies with more than five percent of revenue from oil exploration and production.

**Sell Disciplines.** While the portfolio managers' investment philosophy dictates a long-term investment horizon, the reasons for holding a stock are constantly reviewed and the portfolio managers maintain a strict sell discipline in order to manage overall Fund risk. The portfolio managers typically look to sell stocks primarily for one of the following reasons: (i) the stock has become over-valued; (ii) management disappointment – either in terms of poor results or a change in strategy; (iii) changes in fundamentals – either at corporate, sector or country level; (iv) better opportunities identified elsewhere on a relative basis, or (v) where a company is involved in a negative material ESG incident which compromises the integrity of the business and potentially its ability to generate long-term sustainable EVA, or the portfolio managers' comfort with the company as a corporate citizen.

#### Additional Information About the Fund's Principal Investment Strategies
**Temporary Investments and Other Measures.** The investments and strategies described in this prospectus are those that are used under normal circumstances. During unusual economic, market, political or other circumstances, or during periods of significant shareholder redemptions, the Fund may invest up to 100% of its total assets in short-term, high quality debt instruments, such as U.S. government securities. These instruments would not ordinarily be consistent with the Fund's principal investment strategies, and may prevent the Fund from achieving its investment objective. The Fund will use a temporary strategy if the portfolio managers believe

------

that pursuing the Fund's investment objective will subject the Fund to a significant risk of loss. When the portfolio managers pursue a temporary defensive strategy, the Fund may not profit from favorable developments that it would have otherwise profited from if it were pursuing its normal strategies.

As part of its normal operations, the Fund may hold cash or invest a portion of its portfolio in short-term interest-bearing U.S. dollar denominated securities pending investments or to provide for possible redemptions. Investments in such short-term debt securities can generally be sold easily and have limited risk of loss, but earn only limited returns. The Fund may increase its cash holdings and/or such short-term investments in anticipation of a greater than normal number of shareholder redemptions.

**Percentage Investment Limitations.** Unless otherwise stated, all percentage limitations on Fund investments listed in this prospectus will apply at the time of purchase. The Fund would not violate these limitations unless an excess or deficiency occurs or exists immediately after and as a result of an investment.

**Other Investments and Techniques.** The Fund may invest in other types of securities and use a variety of investment techniques and strategies which are not principal investment strategies and are not described in this prospectus. These securities and techniques may subject the Fund to additional risks. Please see the Statement of Additional Information (the "SAI") for additional information about the securities and investment techniques described in this prospectus and about additional securities and techniques that may be used by the Fund.

#### Additional Information About the Fund's Principal Risks
Many of the investment techniques and strategies discussed in this prospectus and in the SAI are discretionary, which means that the portfolio managers can decide whether to use them. The Fund may invest in these securities or use these techniques as part of the Fund's principal investment strategies. However, the portfolio managers may also use investment techniques or make investments in securities that are not a part of the Fund's principal investment strategies.

The value of your investment in the Fund changes with the values of the Fund's investments. Many factors can affect those values. The factors that are most likely to have a material effect on the Fund's portfolio as a whole are called "principal risks." The discussions below expand on the risks identified in the Fund's summary section of the prospectus as "principal risks." Please see the SAI for a further discussion of the principal and other investment strategies employed by the Fund. **It is possible to lose part or all of your money on an investment in the Fund.**

#### Risks Associated with Investing in Emerging Markets
*Economic and Political Factors:* Investments in securities of issuers located in emerging market countries involve special considerations and risks, including the risks associated with high rates of inflation, the limited liquidity and relatively small market capitalization of the securities markets in emerging market countries, relatively higher price volatility and large amounts of external debt and political, economic and social uncertainties, including the possible imposition of exchange controls or other foreign governmental laws or restrictions which may affect investment opportunities. In addition, with respect to certain emerging market countries there is the possibility of political or social instability or diplomatic developments that could affect investments in those countries. Moreover, individual emerging market country economies may differ favorably or unfavorably from the economies of developed nations in such respects as growth of gross national product, rates of inflation, capital investments resources and self-sufficiency and the balance of payments position.

The economies of some emerging market countries have experienced considerable difficulties in the past. Although in certain cases there have been significant improvements in recent years, many such economies continue to experience significant problems, including high inflation and interest rates. Inflation and rapid fluctuations in interest rates have had and may continue to have very negative effects on the economies and securities markets of certain emerging market countries. The development of certain emerging market economies and securities markets will require continued economic and fiscal discipline, which has been lacking at times in the past, as well as stable political and social conditions. Recovery may also be influenced by international economic conditions, particularly those in the U.S. and by world prices for oil and other commodities. There is no assurance that economic initiatives will be successful. Certain of the risks associated with international investments and investing in smaller capital markets are heightened for investments in emerging market countries.

*Market Liquidity and Volatility:* The securities markets in emerging market countries are substantially smaller, less liquid and more volatile than the major securities markets in the United States and Europe. A limited number of issuers in most, if not all, securities markets in emerging market countries may represent a disproportionately large percentage of market capitalization and trading volume. Such markets may in certain cases, be characterized by relatively few market makers, participants in the market being mostly institutional investors including insurance companies, banks, other financial institutions and investment companies. The listed equity securities of many companies in many emerging markets are accordingly materially less liquid, subject to greater dealing spreads and

------

experience materially greater volatility than those of the Organization for Economic Cooperation and Development ("OECD") countries—an association of 37 member countries in Europe, the Americas and the Pacific. Government supervision and regulation of many emerging markets and of quoted companies is also less developed than in many OECD countries. In addition, there may be a high measure of legal uncertainty concerning the rights and duties of market participants as compared to investments made through securities systems of established markets.

The combination of price volatility and the less liquid nature of securities markets in emerging market countries may, in certain cases, affect the Fund's ability to acquire or dispose of securities at the price and time it wishes to do so, and consequently may have an adverse impact on the investment performance of the Fund.

*Information Standards:* In addition to their smaller size, lesser liquidity and greater volatility, securities markets in emerging markets are less developed than the securities markets in the U.S. and Europe with respect to disclosure, reporting and regulatory standards are less publicly available information about the issuers of securities in these markets than is regularly published by issuers in the United States and Europe. Further, corporate laws regarding fiduciary responsibility and protection of stockholders may be considerably less developed than those in the United States and Europe. Issuers in emerging market countries may not be subject to the same accounting, auditing and financial reporting standards.

*Custody Risk:* In a limited number of markets, particularly in emerging economies, where a no failed trade policy is standard market practice, assets may be assigned, transferred, exchanged or delivered without the prior approval of the Depositary or its agent. Once a sale order is placed in relation to assets of the Fund, by virtue of the operation of the settlement system within those markets, those assets will automatically move from custody of the Depositary without the need for the prior approval of the Depositary. Where this occurs the consideration for those assets is remitted to the entity releasing the assets.

*Currency Risk:* the currencies in which investments are denominated may be unstable, may be subject to significant depreciation and may not be freely convertible.

**Risks Associated with Investing in Smaller-Cap and Mid-Cap Companies.** The prices of securities of smaller-cap and mid-cap companies tend to fluctuate more widely than those of larger, more established companies. Smaller-cap and mid-cap companies may have limited product lines, markets or financial resources or may depend on the expertise of a few people and may be subject to more abrupt or erratic market movements than securities of larger, more established companies or market averages in general. In addition, these companies often have shorter operating histories and are more reliant on key products or personnel than larger companies. The securities of smaller- or medium-sized companies are often traded over-the-counter, and may not be traded in volumes typical of securities traded on a national securities exchange. Securities of such issuers may lack sufficient market liquidity to effect sales at an advantageous time or without a substantial drop in price.

**Risks Associated with Derivative Instruments.** The use of derivative instruments may involve risks different from, or greater than, the risks associated with investing in more traditional investments. Any use of derivatives strategies entails the risks of investing directly in the securities or instruments underlying the derivatives strategies, as well as the risks of using derivatives generally. Derivatives can be highly complex and may perform in ways unanticipated by the Adviser. The use of derivative instruments for the Fund may also expose the Fund to a number of specific risks, depending on the nature of the individual transaction, such as the following:

*Correlation risk:* The value of derivative instruments may be imperfectly correlated to the value of the underlying securities, for example, because of transaction costs and interest rate movements.

*Loss of Favorable Performance risk:* The use of derivatives to hedge or protect against market risk or to generate additional revenue (for example, by writing covered call options on portfolio securities) may reduce the opportunity to benefit from favorable market movements.

*Counterparty exposure and legal documentation risk:* The use of OTC derivatives, such as forward contracts, swap agreements and contracts for differences, will expose the Fund to credit risk with respect to the Fund's counterparty to such transactions and the risk that the legal documentation of the contract may not accurately reflect the intention of the parties and/or that the counterparty may interpret contractual terms differently than the Fund. When the Fund enters into futures transactions or other cleared derivative transactions, it is subject to the counterparty risk of the clearing member and clearing house through which it holds such positions. See "Counterparty and Third Party Risk" and "Collateral Management Risk" below.

*Liquidity risk:* The Fund may not be able to close out or sell a derivative position at an advantageous price or time. Futures positions may also be illiquid or difficult to close out because of limits imposed by the relevant exchange on daily price movements. The portfolio managers will only enter into OTC transactions with counterparties which are contractually obliged to close out a position on request.

------

*Market risk:* Derivative instruments are subject to the general risk that the value of a particular investment or transaction will change in a way detrimental to the Fund's interests. General economic and capital and credit market conditions may have a significant impact on the Fund's derivative instruments. Interest rates, fluctuations in the price of assets and increased competition may adversely affect the value of derivative instruments held by the Fund. The prices of exchange traded derivatives, for example, may also be subject to changes in price due to supply and demand factors.

*Leverage and volatility risk*: When the portfolio managers purchase a security or an option, the risk of the Fund is generally limited to the loss of its investment. In the case of some derivative transactions including certain futures, forwards, swaps, contracts for differences or writing options, the Fund's liability may be potentially unlimited until the position is closed. Derivatives instruments can create investment leverage and may be highly volatile, and the Fund could lose significantly more than the amount it invests.

*Currency Hedging:* Currency hedging, which may be undertaken using derivatives, may provide protection to the Fund from adverse currency movements, but may also release or eliminate the benefit of favorable currency movements. There can also be no guarantee that a decision to hedge any currency exposure will be effective or that the portfolio managers will exercise its discretion to hedge any particular currency exposure. In addition, it may be difficult to effectively hedge exposures in certain currencies either at a reasonable cost or on a practical basis.

*Regulation risk:* Current and future regulation of the derivatives markets and its participants may make derivatives more costly, may limit the availability or liquidity of derivatives, or may otherwise adversely affect the value or performance of derivatives. Any such adverse developments could impair the effectiveness of the Fund's derivatives strategies and cause the Fund to lose value. For instance, the U.S. government has enacted legislation that provides for regulation of the derivatives market, including clearing, margin, reporting, and registration requirements, which could restrict the Fund's ability to engage in derivatives transactions or increase the cost or uncertainty involved in such transactions. The European Union, the United Kingdom and various other jurisdictions have implemented or are in the process of implementing similar requirements, which will affect the Fund when it enters into a derivatives transaction with a counterparty subject to such requirements. In addition, Rule 18f-4 under the 1940 Act governs the use of derivative investments and certain financing transactions (e.g. reverse repurchase agreements) by registered investment companies. Among other things, Rule 18f-4 limits a fund's derivatives exposure through a value-at-risk test and requires the adoption and implementation of a derivatives risk management program. A fund that uses derivative instruments in a limited amount is not be subject to the full requirements of Rule 18f-4. Compliance with the new rule by the Fund could, among other things, make derivatives more costly, limit their availability or utility, or otherwise adversely affect their performance. The new rule may limit the Fund's ability to use derivatives as part of its investment strategy.

*Tax Risk:* The Fund's use of derivatives may be subject to one or more special tax rules that may affect the amount, timing and/or character of distributions to shareholders and could result in the realization of additional taxable income or gains for shareholders.

**ESG Investing Risk.** The Fund's consideration of environmental, social and/or governance factors as part of its investment process may cause it to make different investments than funds that have a similar investment universe and/or investment style but that do not incorporate such factors in their strategy or investment processes. Additionally, the Fund may forgo opportunities to buy certain securities when it might otherwise be advantageous to do so, or sell securities when it might be otherwise disadvantageous for it to do so. Incorporating ESG factors into investment decision making is qualitative and subjective by nature; there is no guarantee that the factors considered by the Adviser or any judgment exercised by the Adviser will reflect the beliefs or values of any particular investor and it is possible that it will have an adverse effect on a Fund's performance. Socially responsible norms differ by region and industry, and a company's ESG practices or the Adviser's assessment of a company's ESG practices may change over time. In evaluating a company or issuer in light of ESG factors, the Adviser may consider information and data obtained through voluntary or third-party reporting that may be incomplete or inaccurate. It is possible the companies or issuers identified through the Adviser's consideration of ESG factors will not operate as expected and will not exhibit positive ESG characteristics to the extent the Adviser might have anticipated.

**Risks Associated with Investing in Non-U.S. Securities.** Since the Fund principally invests in non-U.S. securities, the Fund will be subject to risks not typically associated with domestic securities. Non-U.S. investments involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money.

Certain of the risks noted below may also apply to securities of U.S. issuers with significant non-U.S. operations. Investments in non-U.S. securities involve the following risks:

• The economies of some non-U.S. markets often do not compare favorably with that of the U.S. in areas such as growth of gross domestic product, reinvestment of capital, resources, and balance of payments. Some of these economies may rely

------

heavily on particular industries or non-U.S. capital. They may be more vulnerable to adverse diplomatic developments, the imposition of economic sanctions against a country, changes in international trading patterns, trade barriers and other protectionist or retaliatory measures.

• Governmental actions—such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes—may adversely affect investments in non-U.S. markets. Such governments may also participate to a significant degree, through ownership or regulation, in their respective economies.

• The governments of certain countries may prohibit or substantially restrict foreign investing in their capital markets or in certain industries. This could severely affect security prices. This could also impair the Fund's ability to purchase or sell non-U.S. securities or transfer its assets or income back to the U.S. or otherwise adversely affect the Fund's operations.

• Other non-U.S. market risks include foreign exchange controls, difficulties in pricing securities, defaults on non-U.S. government securities, difficulties in enforcing favorable legal judgments in non-U.S. courts, and political and social instability. Legal remedies available to investors in some non-U.S. countries are less extensive than those available to investors in the U.S. Many non-U.S. governments supervise and regulate stock exchanges, brokers and the sale of securities to a lesser extent than the U.S. government does. Corporate governance may not be as robust as in more developed countries. As a result, protections for minority investors may not be strong, which could adversely affect the Fund's non-U.S. holdings or exposures.

• Accounting standards in other countries are not necessarily the same as in the U.S. If the accounting standards in another country do not require as much disclosure or detail as U.S. accounting standards, it may be harder for the portfolio managers to completely and accurately determine a company's financial condition or otherwise assess a company's creditworthiness.

• Because there may be fewer investors on non-U.S. exchanges and smaller numbers of shares traded each day, it may be difficult for the Fund to buy and sell securities on those exchanges. In addition, prices of non-U.S. securities may be more volatile than prices of securities traded in the U.S.

• Non-U.S. markets may have different clearance and settlement procedures. In certain markets, settlements may not keep pace with the volume of securities transactions. If this occurs, settlement may be delayed, and the Fund's assets may be uninvested and may not be earning returns. The Fund also may miss investment opportunities or not be able to sell an investment or reduce its exposure because of these delays.

• Changes in currency exchange rates will affect the value of the Fund's non-U.S. holdings or exposures.

• The costs of non-U.S. securities transactions tend to be higher than those of U.S. transactions, increasing the transaction costs paid directly or indirectly by the Fund.

• International trade barriers or economic sanctions against non-U.S. countries may adversely affect the Fund's non-U.S. holdings or exposures.

• Global economies are increasingly interconnected, which increases the possibilities that conditions in one country, region or financial market may adversely impact a different country, region or financial market.

The severity or duration of these conditions may be affected if one or more countries leave the European Union, the euro currency or if other policy changes are made by governments or quasi-governmental organizations.

The Fund may invest in depositary receipts, including American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs") and Global Depositary Notes ("GDNs"), which are certificates evidencing ownership of securities of a non-U.S. issuer. Depositary receipts may be sponsored by the non-U.S. issuer or unsponsored. Depositary receipts are subject to the risks of changes in currency or exchange rates and the risks of investing in non-U.S. securities that they evidence or into which they may be converted. The issuers of unsponsored depositary receipts are not obligated to disclose information that would be considered material in the U.S., or to pass through to shareholders any voting rights with respect to the deposited securities. Therefore, there may be less information available regarding these issuers, and there may not be a correlation between such information and the market value of the depositary receipts.

**Exposure to Greater China.** Although the Fund does not intend to invest directly in Chinese issuers, the Fund may have limited exposure to the Chinese economy, as a consequence of the indirect exposure that companies in other Emerging Market countries may have to China. For example, companies in Emerging Markets countries may have some economic or risk exposure to China if a portion of their revenues derive from China, or if their products are manufactured using raw materials or component parts sourced from China or from Chinese countries. The Fund's exposure to China may indirectly subject the Fund to certain risks and considerations not typically associated with investing in other more established economies or securities markets. Such risks may include, among others: (a) political and regulatory uncertainties such as international and Chinese political developments and changes

------

in governmental policies in areas including taxation, foreign investment, currency repatriation, currency fluctuation and foreign exchange control; (b) legal and/or accounting risks; liquidity risk; (c) market risk, including the risk of high rates of inflation, high interest rates, currency depreciation and fluctuation and also changes in taxation legislation and interpretation that may affect an investor's income and the value of its investments; and (d) greater social and economic uncertainty.

**Market Risk.** The market price of investments owned by the Fund may go up or down, sometimes rapidly or unpredictably. Fund investments may decline in value due to factors affecting the overall markets, or particular industries or sectors. The value of a holding may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for an issuer's financial condition, changes in interest or currency rates, domestic or international monetary policy or adverse investor sentiment generally. The value of a holding may also decline due to factors that affect a particular industry or industries, such as competitive conditions within an industry or government regulations. The Fund may experience heavy redemptions, which could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of an investment in the Fund to unexpectedly decline. The Fund may rely on various third-party sources to calculate its net asset value. Errors or systems failures and other technological issues may adversely impact the Fund's calculation of its net asset value, and such net asset value calculation issues may result in inaccurately calculated net asset values, delays in net asset value calculation and/or the inability to calculate net asset values over extended periods. The Fund may be unable to recover any losses associated with such failures.

**Equity Securities Risk.** Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Equity securities may take the form of shares of common stock of a corporation, membership interests in a limited liability company, limited partnership interests, or other forms of ownership interests. Equity securities also include, among other things, preferred stocks, convertible securities and warrants. The value of a company's equity securities may fall as a result of factors directly relating to that company, such as decisions made by its management or lower demand for the company's products or services. The value of an equity security may also fall because of factors affecting not just the company, but also companies in the same industry or in a number of different industries, such as increases in production costs. The value of a company's equity securities may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates or adverse circumstances involving the credit markets. In addition, because a company's equity securities rank junior in priority to the interests of bond holders and other creditors, a company's equity securities will usually react more strongly than its bonds and other debt to actual or perceived changes in the company's financial condition or prospects. To the extent the Fund invests in equity-related instruments it will also be subject to these risks.

The Fund may invest in equity securities of companies that the portfolio managers believe will experience relatively rapid earnings growth ("growth securities") or that the portfolio managers believes are selling at a price lower than their true value ("value securities"). Growth securities typically trade at higher multiples of current earnings than other securities. Therefore, the value of growth securities may be more sensitive to changes in current or expected earnings than the value of other securities. Companies that issue value securities may have experienced adverse business developments or may be subject to special risks that have caused their securities to be out of favor. If the portfolio managers' assessment of a company's prospects is wrong, or if the market does not recognize the value of the company, the price of its securities may decline or may not approach the value that the portfolio managers anticipate.

**Counterparty and Third-Party Risk.** Transactions involving a counterparty to a derivative or other instrument or transaction (e.g., a repurchase agreement or securities loan), or a third party responsible for servicing the instrument or transaction, are subject to the credit risk of the counterparty or third party, and to the counterparty's or third party's ability to perform in accordance with the terms of the transaction. When the Fund enters into futures transactions or other cleared derivative transactions, it is subject to the counterparty risk of the clearing member and clearing house through which it holds such positions. Counterparty risk is the risk that the issuer, guarantor, counterparty or third party to a particular instrument, investment or transaction becomes unable or unwilling to make timely principal, interest, or settlement payments or otherwise to honor its obligations. This risk is particularly acute in environments (like those experienced recently) in which financial services firms are exposed to systemic risks.

If a counterparty defaults, the Fund may have contractual remedies, but the Fund may be unable to enforce them. The obligations of counterparties are subject to bankruptcy, insolvency, and other laws affecting the rights and remedies of creditors. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract (whether OTC or cleared), the Fund may experience significant delays in obtaining any recovery under the derivative contract, particularly if the counterparty becomes subject to an insolvency, resolution or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances. If a counterparty defaults, the Fund may have to participate in legal proceedings involving the counterparty. This could increase the Fund's operating expenses and decrease its net asset value. If a counterparty's obligation to the Fund is not collateralized, then the Fund is essentially an unsecured creditor of the counterparty. Counterparty risk is still present even if a counterparty's obligations are secured by collateral because, for example, the Fund's interest in collateral may not be perfected, additional collateral may not be promptly posted as required, and/or the Fund's recovery of collateral may be limited by applicable insolvency laws.

------

The Fund is also subject to counterparty risk to the extent it executes a significant portion of its securities transactions through a broker, dealer, or counterparty to a derivatives transaction, such as a futures commission merchant. If the broker, dealer or other counterparty fails to meet its contractual obligations, goes bankrupt, or otherwise experiences a business interruption, the Fund could, for example, miss investment opportunities or be unable to dispose of investments it would prefer to sell at favorable times or prices, resulting in losses for the Fund.

Derivatives transactions, especially over-the-counter derivatives, involve significant counterparty risk. Those derivative instruments involving high amounts of counterparty risk, include, among others, swaps (including interest rate swaps, total return swaps and credit default swaps), structured notes, forward currency contracts, and over-the-counter options contracts. For centrally cleared derivatives, such as cleared swaps, futures and many options the primary credit/counterparty risk is the creditworthiness of the Fund's clearing broker and the central clearing house itself. While exchange-traded and centrally cleared derivatives are generally perceived to present less counterparty risk because they are guaranteed by the relevant exchange or clearing house, the Fund is still exposed to counterparty risk, including the fraud or insolvency of the broker, exchange and clearing house through which the transaction is undertaken.

**Currency Risk.** The Fund's shares are priced (purchased and redeemed) in U.S. dollars and the distributions paid by the Fund are paid in U.S. dollars. However, a substantial portion of the Fund's assets may be denominated in foreign (non-U.S.) currencies and income received by the Fund from many of its investments may be paid in foreign currencies. Foreign currencies may decline in value relative to the U.S. dollar and adversely affect the value of the Fund's investments in foreign currencies, securities denominated in foreign currencies, derivatives that provide exposure to foreign currencies, and the Fund's income available for distribution. The values of foreign currencies, securities denominated in foreign currencies or derivatives that provide exposure to foreign currencies may be adversely affected by currency exchange rates, currency exchange control regulations, foreign withholding or other taxes, restrictions or prohibitions on the repatriation of foreign currencies, diplomatic developments, such as the imposition of economic sanctions against a particular country or countries, organizations, entities and/or individuals, changes in supply and demand in the currency exchange markets, actual or perceived changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks, or supranational agencies such as the International Monetary Fund, and currency controls or other political and economic developments in the U.S. or abroad. The local emerging market currencies in which the Fund may be invested from time to time may experience substantially greater volatility against the U.S. dollar than the major convertible currencies of developed countries. To the extent the Fund has invested in debt instruments of companies located or doing business in foreign markets and that have issued debt instruments denominated in U.S. dollars or another non-local currency, fluctuations in currency exchange rates could also negatively impact such investments. For example, increases in the value of the U.S. dollar relative to its value at the time the debt was issued can increase the costs of interest and repayment to the issuer and could result in defaults on an issuer's debt obligations.

Officials in foreign countries may from time to time take actions in respect of their currencies which could significantly affect the value of the Fund's assets denominated in those currencies or the liquidity of such investments. For example, a foreign government may unilaterally devalue its currency against other currencies, which would typically have the effect of reducing the U.S. dollar value of investments denominated in that currency. A foreign government may also limit the convertibility or repatriation of its currency or assets denominated in its currency, which would adversely affect the U.S. dollar value and liquidity of investments denominated in that currency. In addition, although at times most of the Fund's income may be received or realized in these currencies, the Fund will be required to compute and distribute its income in U.S. dollars. As a result, if the exchange rate for any such currency declines after the Fund's income has been earned and translated into U.S. dollars but before payment to shareholders, the Fund could be required to liquidate portfolio securities to make such distributions. Similarly, if the Fund incurs an expense in U.S. dollars and the exchange rate declines before the expense is paid, the Fund would have to convert a greater amount to U.S. dollars to pay for the expense at that time than it would have had to convert at the time the Fund incurred the expense.

Some of the local currencies in which the Fund may invest are neither freely convertible into one of the major currencies nor internationally traded. The local currencies may be convertible into other currencies only inside the relevant emerging market where the limited availability of such other currencies may tend to inflate their values relative to the local currency in question. Such internal exchange markets can therefore be said to be neither liquid nor competitive. In addition, many of the currencies of Emerging Markets in which the Fund may invest have experienced steady devaluation relative to freely convertible currencies.

The portfolio managers may, but are not required to, attempt to mitigate (or "hedge") the risks associated with currency fluctuations by entering into forward, futures and options or other contracts to purchase or sell the currency of denomination of any investment held by the Fund and any other currencies held by the Fund. Such contracts may not be available on favorable terms or in all of the currencies in which the Fund may invest from time to time. In the case of hedging positions, currency risk includes the risk that the currency to which the Fund has obtained exposure declines in value relative to the foreign currency being hedged. In such event, the Fund may realize a loss on the hedging.

------

**Valuation Risk.** Certain securities and instruments may be difficult to value, and to the extent the Fund sells a security or instrument at a price lower than that used to value the security, the Fund's net asset value will be adversely affected. A portion of the Fund's assets may be valued by the Adviser at fair value pursuant to guidelines approved by the Board of Trustees. The Fund's assets may be valued using prices provided by a pricing service or, alternatively, a broker-dealer or other market intermediary (sometimes just one broker-dealer or other market intermediary) when other reliable pricing sources may not be available. To the extent the Fund relies on a pricing service to value some or all of its portfolio securities, it is possible that the pricing information provided by the service will not reflect the actual price the Fund would receive upon sale of a security. When the Fund invests in other mutual funds or investment pools, it will generally value its investments in those funds or pools based on the valuations determined by the funds or pools, which may not be precisely the same as if the net assets of the funds or pools had been valued using the procedures employed by the Fund to value its own assets. Valuation risks may be heightened to the extent that the Fund invests in high yield securities, illiquid securities and derivative instruments because there may be less liquid markets for these instruments or market quotations may not be readily available for them.

**Risks Associated with Non-Diversification.** The Fund is non-diversified, which generally means that it may invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, The Fund's value will likely be more volatile than the value of a more diversified fund. In addition, due to its relatively low number of holdings, the Fund will be more susceptible to company-specific events and risks impacting the particular securities held by the Fund than a fund with a greater number of holdings.

**Cyber Security Risk.** The Fund and its service providers are susceptible to operational and information security and related risks of cyber security incidents. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber security attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through "hacking" or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data or causing operational disruption. Cyber-attacks also may be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make services unavailable to intended users). Cyber security incidents affecting the Fund, Adviser, Custodian or Administrator or other service providers such as financial intermediaries have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, including by interference with the Fund's ability to calculate its NAV; impediments to trading for the Fund's portfolio; the inability of Shareholders to transact business with the Fund; violations of applicable privacy, data security or other laws; regulatory fines and penalties; reputational damage; reimbursement or other compensation or remediation costs; legal fees; or additional compliance costs. Similar adverse consequences could result from cyber security incidents affecting issuers of securities in which the Fund invests, counterparties with which the Fund engages in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies and other financial institutions and other parties. While information risk management systems and business continuity plans have been developed which are designed to reduce the risks associated with cyber security, there are inherent limitations in any cyber security risk management systems or business continuity plans, including the possibility that certain risks have not been identified.

#### Information About the Fund's Non-Principal Investment Strategies and Risks
**Derivatives.** Futures, forwards, options, contracts for difference and swaps may be used to hedge against downward movements in the value of the Fund's portfolio, either by reference to specific securities (i.e. equity or equity related securities) or markets to which the Fund may be exposed. These derivative instruments may also be used to gain or reduce the Fund's exposure to equity or equity related securities or markets on a short or medium term basis where the portfolio managers believe it is more efficient to use derivatives for this purpose, or to gain indirect exposure to equity or equity related securities where the portfolio managers feel that such use of financial derivative instruments is in the best interests of the Fund.

------

**Risks Associated with Collateral Management.** When the Fund enters into a derivative transaction or a securities financing transaction, it will generally be required to post collateral in respect of such transactions. Collateral that the Fund posts to a counterparty or a broker that is not segregated with a third-party custodian may not have the benefit of additional customer-protected "segregation" of such assets. Therefore in the event of the insolvency of a counterparty or a broker, the Fund may become subject to the risk that it may not receive the return of its collateral or that the collateral may take some time to be returned if the collateral becomes available to the creditors of the relevant counterparty or broker. In addition, the Fund is subject to the risk that it will be unable to liquidate collateral provided to it to cover the costs incurred as a result of the counterparty default. The Fund is also subject to the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events.

When cash collateral received by the Fund is re-invested, the Fund will be exposed to the risk of a failure or default of the issuer of the relevant security in which the cash collateral has been invested.

When collateral is posted to a counterparty or broker by way of a title transfer collateral arrangement or where the Fund grants a right of re-use under a security collateral arrangement which is subsequently exercised by the counterparty, the Fund will only have an unsecured contractual claim for the return of equivalent assets. In the event of the insolvency of a counterparty, the Fund shall rank as an unsecured creditor and may not receive equivalent assets or recover the full value of the assets. Investors should assume that the insolvency of any counterparty would result in a loss to the Fund, which could be material. In addition, assets subject to a right of re-use by a counterparty may form part of a complex chain of transactions over which the Fund or its delegates will not have any visibility or control. Because the posting of collateral is effected through the use of standard contracts, the Fund may be exposed to legal documentation risks such as the contract may not accurately reflect the intentions of the parties, the counterparty may interpret contractual terms differently than the Fund, and/or the contract may not be enforceable against the counterparty in its jurisdiction of incorporation.

**Market Disruption and Geopolitical Risk.** The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. War, terrorism, and related geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse long-term effects on U.S. and world economies and markets generally. Natural and environmental disasters, epidemics or pandemics and systemic market dislocations may also be highly disruptive to economies and markets. Those events as well as other changes in non-U.S. and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the investments of the Fund. Given the interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the U.S.

*Russia Sanctions Risk*. In late February 2022, Russian military forces invaded Ukraine, significantly amplifying already existing geopolitical tensions among Russia, Ukraine, Europe, NATO, and the West. Russia's invasion, the responses of countries and political bodies to Russia's actions, and the potential for wider conflict may increase financial market volatility and could have severe adverse effects on regional and global economic markets, including the markets for certain securities and commodities such as oil and natural gas. Following Russia's actions, various countries, including the U.S., Canada, the United Kingdom, Germany, and France, as well as the EU, issued broad-ranging economic sanctions against Russia. Sanctions threatened or imposed by these jurisdictions, and other intergovernmental actions that have been or may be undertaken in the future, against Russia, Russian entities or Russian individuals, may result in the devaluation of Russian currency, a downgrade in the country's credit rating, an immediate freeze of Russian assets, a decline in the value and liquidity of Russian securities, property or interests, and/or other adverse consequences to the Russian economy or a Fund. The scope and scale of sanctions in place at a particular time may be expanded or otherwise modified in a way that may have negative effects on a Fund. Sanctions, or the threat of new or modified sanctions, could impair the ability of a Fund to buy, sell, hold, receive, deliver or otherwise transact in certain affected securities or other investment instruments. Sanctions could also result in Russia taking counter measures or other actions in response, which may further impair the value and liquidity of Russian securities. The extent and duration of the military actions associated with Russia's invasion of Ukraine, the resulting sanctions, and the resulting disruption of the Russian economy, are impossible to predict, but may cause volatility in other regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, which could have a negative effect on the performance of a Fund, even if a Fund does not have direct exposure to securities of Russian issuers.

This prospectus has been designed to meet the regulatory purpose of providing information concerning the Trust and the Fund that you should consider carefully in determining whether to purchase shares of the Fund. Neither this prospectus, the SAI, nor the Fund's registration statement, is intended, or should be read, to be or to give rise to an agreement or contract between the Trust or the Fund and any shareholder, or to give rise to any rights in any shareholder or other person other than any rights under federal or state law that may not be waived. This paragraph is not intended to limit any rights granted to shareholders under federal or state securities laws.

The Fund is open for business every day the New York Stock Exchange ("NYSE") opens for regular trading (each such day, a "Business Day"). When you buy and sell shares of the Fund, the price of the shares is based on the Fund's net asset value ("NAV") per share next determined after the order is received.

#### SHARES

#### Calculating the Fund's Net Asset Value ("NAV")
The NAV of the Fund's shares is determined by dividing the total value of the Fund's portfolio investments and other assets, less any liabilities, by the total number of shares outstanding of the Fund. The NAV per share is calculated at the close of trading of the New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time ("ET")/3:00 p.m. Central time ("CT"), on each day that the NYSE is open for business.

------

The Fund reserves the right to change the time its NAV is calculated under certain unusual circumstances, including, for example, in the event of an unscheduled halt or early close of trading on the NYSE. Your order to purchase or sell shares is priced at the next NAV calculated after your order is received in good order by the Fund or a financial intermediary. Only purchase orders received in good order by the Fund before 4:00 p.m. ET/3:00 p.m. CT will be effective at that day's NAV. On occasion, the NYSE will close before 4:00 p.m. ET/3:00 p.m. CT. When that happens, purchase requests received by the Fund or a financial intermediary after the NYSE closes will be effective the following business day. The NAV of the Fund may change every day.

A purchase or redemption request is considered to be "in good order" when all necessary information is provided and all required documents are properly completed, signed, and delivered. Requests must include the following:

• The account number (if issued) and Fund name;

• The amount of the transaction, in dollar amount or number of shares;

• For redemptions (other than online, telephone or wire redemptions), the signature of all account owners exactly as they are registered on the account;

• Required signature guarantees, if applicable; and

• Other supporting legal documents and certified resolutions that might be required in the case of estates, corporations, trusts and other entities or forms of ownership. Call (800) 806-1112 (toll free) or (312) 557-3164 for more information about documentation that may be required of these entities.

Additionally, a purchase order initiating the opening of an account is not considered to be in "good order" unless you have provided all information required by the Fund's "Customer Identification Program" as described below.

#### Valuing the Fund's Assets
The market value of the Fund's investments is determined primarily on the basis of readily available market quotations. The Fund is directed by the Board of Trustees to use various approved pricing services and market makers to determine the market value of securities. Foreign securities, currencies and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the prevailing exchange rate of such currencies against the U.S. Dollar as provided by an independent pricing service approved by the Board of Trustees.

If market quotations for a security are not readily available or market quotations or a price provided by a pricing service do not reflect fair value, or if an event occurs after the close of trading on the domestic or foreign exchange or market on which the security is principally traded (but prior to the time the NAV is calculated) that materially affects fair value, the Adviser, acting through its Fair Value Committee, is responsible for valuing the Fund's assets at their fair value according to policies approved by the Board of Trustees.

Other fair value situations could include, but are not limited to: (1) extremely illiquid securities in which there is no trading market and no broker coverage; (2) stale priced securities; (3) securities that may be defaulted or de-listed from an exchange and are no longer trading; or (4) any other security in which the Adviser, Fund Accountant or Fair Value Committee identify that the current price may not be reliable. If it has been determined that an event that has materially affected the value of the Fund's securities has taken place, the Fair Value Committee will make a determination of the fair price for the impacted securities according to policies approved by the Board.

Without a fair value price, short-term investors could take advantage of the arbitrage opportunity and dilute the NAV of long-term investors. Foreign markets in which the Fund buys securities may be open on days the U.S. markets are closed, causing the Fund's NAV to change even though the Fund is closed. While fair valuation of the Fund's portfolio securities can serve to reduce arbitrage opportunities, there is no assurance that fair value pricing policies will prevent dilution of the NAV by short-term investors. Fair valuation involves subjective judgments, and it is possible that the fair value determined for a security may differ materially from the value that could be realized upon the sale of the security.

Pursuant to Rule 2a-5 under the 1940 Act, the Fund's Board has designated the Fund's Adviser through its Fair Valuation Committee as the Fund's "Valuation Designee" to perform the Fund's fair value determinations, which are subject to Board oversight and certain reporting and other requirements intended to ensure that the Board receives the information it needs to oversee the Adviser's fair valuation determinations. This establishes requirements for determining fair value in good faith for purposes of the 1940 Act.

#### Customer Identification Program: Important Information About Procedures for Opening an Account
Federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you open an account, we will ask for your name, residential address, date of birth, government identification number and other information that will allow us to identify you. For legal entity customers, we will also ask that any individual(s) who, directly or indirectly, owns 25% or more of the entity and one individual who has significant responsibility to control, manage, or direct the legal entity be identified. We also may ask to see your driver's license or other identifying documents.

If we do not receive the required information, there may be a delay in processing your investment request, which could subject your investment to market risk. If we are unable to immediately verify your identity, the Fund may restrict further investment until your identity is verified. However, if we are unable to verify your identity, the Fund reserves the right to close your account without notice and return your investment to you at the NAV determined on the day in which your account is liquidated. If we close your account because we are unable to verify your identity, your investment will be subject to market fluctuation, which could result in a loss of a portion of your principal investment. If your account is closed at the request of governmental or law enforcement authorities, the Fund may be required by the authorities to withhold the proceeds.

------

The price you will receive when you redeem your shares will be the NAV next determined after the Fund receives your properly completed order to sell. You may receive proceeds from the sale by check, bank wire transfer or direct deposit into your bank account and in certain cases, payment may be made in securities of the Fund as described in "Additional Information About Redemptions." The proceeds may be more or less than the purchase price of your shares, depending on the market value of the Fund's securities at the time your redemption request is received. A financial intermediary may charge a transaction fee to redeem shares. In the event that a wire transfer is impossible or impractical, the redemption check will be sent by mail to the designated account.

#### Redemptions Through a Financial Intermediary
If you purchased shares from a financial intermediary, you may sell (redeem) shares by contacting your financial intermediary.

------

#### Medallion Signature Guarantee
Some circumstances require that your request to redeem shares be made in writing accompanied by an original Medallion Signature Guarantee. A Medallion Signature Guarantee helps protect you against fraud. You can obtain a Medallion Signature Guarantee from most banks or securities dealers, but not from a notary public. You should verify with the institution that it is an eligible guarantor prior to signing. The recognized medallion program is Securities Transfer Agent Medallion Program. SIGNATURE GUARANTEES RECEIVED FROM INSTITUTIONS NOT PARTICIPATING IN THIS PROGRAM WILL NOT BE ACCEPTED. The Medallion Signature Guarantee must cover the amount of the requested transaction. There are several different guarantee amounts, so it is important to acquire a guarantee amount equal to or greater than the amount of the transaction. If the surety bond of the Medallion Guarantee is less than the transaction amount, your request may be rejected.

An original Medallion Signature Guarantee is required if any of the following applies:

• the redemption is requested in writing and the amount redeemed is greater than $100,000;

• the name(s) or the address on your account or the name or address of a payee has been changed within 30 days of your redemption request;

• information on your investment application has been changed within the last 30 days (including a change in your name or your address);

• proceeds or shares are being sent/transferred from a joint account to an individual's account; or

• proceeds are being sent via wire or ACH and bank instructions have been added or changed within 30 days of your redemption request.

If your written request is for redemption greater than $5 million, call (800) 806-1112 (toll free) or (312) 557-3164 for Medallion Signature Guarantee requirements.

#### Additional Information About Redemptions
The Fund typically expects that it will pay redemption proceeds by check or electronic transfer within seven (7) calendar days after receipt of a proper redemption request, although proceeds normally are paid within four (4) business days. If you are redeeming shares that have been purchased via ACH, the Fund may hold proceeds until the purchase amount has been collected, which may be as long as five (5) business days after purchase date. To eliminate this delay, you may purchase shares of the Fund by wire. Also, when the NYSE is closed (or when trading is restricted) for any reason other than its customary weekend or holiday closing or under any emergency circumstances, as determined by the Securities and Exchange Commission, the Fund may suspend redemptions or postpone payment of redemption proceeds. The Fund typically expects to pay redemptions from cash, cash equivalents, proceeds from the sale of Fund shares, any lines of credit, and then from the sale of portfolio securities. These redemption payment methods will be used in both regular and stressed market conditions.

At the discretion of the Fund or the Transfer Agent, corporate investors and other associations may be required to furnish an appropriate certification authorizing redemptions to ensure proper authorization.

Generally, all redemptions will be for cash. However, if you redeem shares worth the lesser of $250,000 or 1% of the NAV of the Fund, the Fund reserves the right to pay part or all of your redemption proceeds in readily marketable securities instead of cash at the discretion of the Fund. Shareholders may incur brokerage charges on the sale of any securities distributed in lieu of cash and will bear market risk until the security is sold. Redemption-in-kind proceeds are distributed to the redeeming shareholder based on a weighted-average pro rata basis of a fund's holdings. If payment is made in securities, the Fund will value the securities selected in the same manner in which it computes its NAV. This process minimizes the effect of large redemptions on the Fund and its remaining shareholders. Redemptions are taxable events whether redemption proceeds are paid in cash or in-kind. As with any security, a shareholder will bear taxes on any capital gains from the sale of a security distributed in a redemption-in-kind.

#### DIVIDENDS AND DISTRIBUTIONS
The Fund intends to distribute substantially all of its net investment income as dividends to its shareholders on at least an annual basis. The Fund intends to distribute any net realized long-term capital gains and its net realized short-term capital gains, if any, at least once a year. The Fund may distribute income dividends and capital gains more frequently, if necessary, in order to reduce or eliminate federal excise or income taxes on the Fund. The amount of any distribution varies and there is no guarantee the Fund will pay either income dividends or capital gain distributions.

------

Income dividends and capital gain distributions are automatically reinvested in additional shares of the Fund at the applicable NAV on the distribution date unless you request cash distributions on your application or through a written request. If cash payment is requested, a check normally will be mailed within five business days after the payable date.

If you elect to receive income dividends and capital gain distributions in cash and the payment is returned and marked as "undeliverable" or is not cashed for six months, your cash election may be changed automatically and future dividends will be reinvested in the Fund at the NAV determined as of the date of payment. In addition, any undeliverable checks or checks that are not cashed for six months may be cancelled and the proceeds reinvested in the Fund at the NAV determined as of the date of cancellation.

#### Frequent Purchases and Redemptions of Fund Shares
The Fund is intended to be a long-term investment. Excessive purchases and redemptions of shares of the Fund in an effort to take advantage of short-term market fluctuations, known as "market timing," can interfere with long-term portfolio management strategies and increase the expenses of the Fund, to the detriment of long-term investors. Because the Fund will invest its assets in foreign securities, investors may seek to take advantage of time zone differences between the foreign markets on which the Fund's portfolio securities trade and the time at which the NAV is calculated. For example, a market-timer may purchase shares of the Fund based on events occurring after foreign market closing prices are established but before the NAV calculation, that are likely to result in higher prices in foreign markets the next day. The market-timer would then redeem the Fund's shares the next day when the Fund's share price would reflect the increased prices in foreign markets, realizing a quick profit at the expense of long-term Fund shareholders.

Excessive short-term trading may (1) require the Fund to sell securities in the Fund's portfolio at inopportune times to fund redemption payments, (2) dilute the value of shares held by long-term shareholders, (3) cause the Fund to maintain a larger cash position than would otherwise be necessary, (4) increase brokerage commissions and related costs and expenses, and (5) generate additional tax liability for shareholders or the Fund. Accordingly, the Board of Trustees has adopted policies and procedures that seek to restrict market timing activity. Under these policies, the Fund periodically examines transactions that exceed monetary thresholds or numerical limits within certain time periods. If the Fund believes, in its sole discretion, that an investor is engaged in excessive short-term trading or is otherwise engaged in market timing activity, the Fund may, with or without prior notice to the investor, reject further purchase orders from that investor, and disclaim responsibility for any consequent losses that the investor may incur related to the rejected purchases. Alternatively, the Fund may limit the amount, number or frequency of any future purchases and/or the method by which an investor may request future purchases and redemptions. The Fund's response to any particular market timing activity will depend on the facts and circumstances of each case, such as the extent and duration of the market timing activity and the investor's trading history in the Fund. While the Fund cannot assure the prevention of all excessive trading and market timing, by making these judgments, the Fund believes it is acting in a manner that is in the best interests of shareholders.

Financial intermediaries may establish omnibus accounts with the Fund. Omnibus accounts include multiple investors and typically provide the Fund with a net purchase or redemption. The identity of individual investors ordinarily are not known to or tracked by the Fund. The Fund will enter into information sharing agreements with certain financial intermediaries under which the financial intermediaries are obligated to: (1) enforce during the term of the agreement, a market-timing policy, the terms of which are acceptable to the Fund; (2) furnish the Fund, upon request, with information regarding customer trading activities in shares of the Fund; and (3) enforce the Fund's market-timing policy with respect to customers identified by the Fund as having engaged in market timing.

The Fund applies these policies and procedures to all shareholders believed to be engaged in market timing or excessive trading. While the Fund may monitor transactions at the omnibus account level, the netting effect makes it more difficult to identify and eliminate market-timing activities in omnibus accounts. The Fund has no arrangements to permit any investor to trade frequently in shares of the Fund, nor will it enter into any such arrangements in the future.

Financial intermediaries maintaining omnibus accounts with the Fund may impose market timing policies that are more restrictive than the market timing policy adopted by the Board of Trustees. For instance, these financial intermediaries may impose limits on the number of purchase and sale transactions that an investor may make over a set period of time and impose penalties for transactions in excess of those limits. Financial intermediaries also may exempt certain types of transactions from these limitations. If you purchased your shares through a financial intermediary, you should read carefully any materials provided by the financial intermediary together with this prospectus to fully understand the market timing policies applicable to you.

#### Payments to Financial Intermediaries
The Adviser may, at its own expense and out of its own profits, provide additional cash payments to financial intermediaries who sell shares of the Fund and/or whose clients or customers hold shares of the Fund. These additional payments generally are made to financial intermediaries that provide shareholder or administrative services, or distribution related services. Payments generally are

------

based on either (1) a percentage of the average daily net assets of clients serviced by such financial intermediary, or (2) the number of accounts serviced by such financial intermediary. These additional cash payments also may be made as an expense reimbursement in cases where the financial intermediary provides shareholder services to Fund shareholders.

#### TAXES
The following discussion is only a summary of certain U.S. federal income tax issues generally affecting the Fund and its shareholders. Except where noted, the following discussion addresses only the U.S. federal income tax consequences of an investment in the Fund and does not address any non-U.S., state, or local tax consequences. The following assumes that the Fund's shares will be capital assets in the hands of a shareholder. Circumstances among investors may vary, so you are encouraged to discuss investment in the Fund with your tax adviser.

The Fund intends to meet all requirements under Subchapter M of the Internal Revenue Code 1986, as amended (the "Code") necessary to qualify and be eligible each year for treatment as a "regulated investment company," and thus does not expect to pay any U.S. federal income tax on income and capital gains that are timely distributed to shareholders. The Fund's failure to qualify as a regulated investment company would result in Fund-level taxation and would adversely affect shareholders' investment in Fund shares.

#### Taxation of Fund Distributions
The Fund intends to distribute all, or substantially all, of its net investment income and net capital gains (i.e., the excess of net long-term capital gains over net short-term capital losses, in each case determined with reference to any loss carryforwards) to its shareholders each year. Although the Fund will not be taxed on amounts it distributes, most shareholders will be taxed on amounts they receive.

For U.S. federal income tax purposes, distributions of investment income are generally taxable to Fund shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long the Fund owned (or is deemed to have owned) the investments that generated them, rather than how long a shareholder has owned his or her shares. Distributions attributable to the excess of net long-term capital gains from the sale of investments the Fund owned (or is deemed to have owned) for more than one year over net short-term capital losses from the sale of investments the Fund owned (or is deemed to have owned) for one year or less, that are properly reported by the Fund as capital gain dividends ("Capital Gain Dividends") will generally be taxable to a shareholder receiving such distributions as long-term capital gain includible in net capital gain and taxed to individuals at reduced rates. Distributions attributable to the excess of net short-term capital gains over net long-term capital losses will be taxable as ordinary income.

Distributions of investment income made to a non-corporate shareholder properly reported by the Fund as derived from "qualified dividend income," if any, received by the Fund will be subject to tax at the lower rates applicable to net capital gains, provided that the shareholder and the Fund meet certain holding period and other requirements.

Distributions are subject to U.S. federal income taxes as described herein whether received as cash or reinvested in additional shares. In addition, Fund distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price the shareholder paid for his or her shares). Such distributions are likely to occur in respect of shares purchased at a time when the Fund's NAV reflects gains that are either unrealized or realized but not distributed. Distributions may also be subject to state and local taxes.

An additional 3.8% Medicare contribution tax is imposed on certain net investment income of U.S. individuals, estates and trusts to the extent that such person's "modified adjusted gross income" (in the case of an individual) or "adjusted gross income" (in the case of an estate or trust) exceeds certain threshold amounts. Net investment income generally includes for this purpose dividends, including any Capital Gain Dividends, paid by the Fund, and net capital gains recognized on the sale, redemption or other taxable disposition of shares of the Fund.

Dividends declared by the Fund and payable to shareholders of record in October, November or December of one year and paid in January of the next year generally are taxable in the year in which the dividends are declared, rather than the year in which the dividends are received.

You will be notified annually of the amount of income, dividends and net capital gains distributed. If you purchase shares of the Fund through a financial intermediary, that entity will provide this information to you.

------

**Redemption or Sale of Fund Shares.** Selling or redeeming your Fund shares is a taxable event and may result in the recognition of gain or loss. Gain or loss, if any, recognized by a shareholder on a redemption, sale or other taxable disposition of Fund shares generally will be taxed as long-term capital gain or loss if the shareholder held the shares for more than one year, and as short-term capital gain or loss if the shareholder held the shares for one year or less. Short-term capital gains generally are taxed at the rates applicable to ordinary income. Any loss realized upon a disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any Capital Gain Dividends received by the shareholder with respect to the shares. The deductibility of capital losses is subject to limitations. See "Cost Basis Reporting" below for information about certain cost basis reporting obligations. Additionally, any loss realized on a sale or redemption of shares of the Fund may be disallowed under "wash sale" rules to the extent the shares disposed of are replaced with other shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after the shares are disposed of, such as pursuant to a dividend reinvestment in shares of the Fund. If disallowed, the loss will be reflected in an adjustment to the tax basis of the shares acquired. You are responsible for any tax liabilities generated by your transactions.

**Taxation of Certain Fund Investments.** Investment income and proceeds received by the Fund from sources within foreign countries may be subject to foreign withholding or other taxes. In that case, the Fund's yield on those securities would be decreased. The United States has entered into tax treaties with many foreign countries which may entitle the Fund to a reduced rate of such taxes or exemption from taxes on such income or proceeds. It is impossible to determine the effective rate of foreign tax for the Fund in advance since the amount of the assets to be invested within various countries is not known.

If more than 50% in value of the Fund's total assets at the close of its taxable year consists of stock or securities of foreign corporations, the Fund may elect to "pass through" to its shareholders the amount of foreign income and similar foreign taxes paid or deemed paid by it. If the Fund so elects, each of its shareholders would be required to include in gross income, even though not actually received, its pro rata share of such foreign taxes paid or deemed paid by the Fund, but would be treated as having paid its pro rata share of such foreign taxes and would therefore be allowed to either deduct such amount in computing taxable income or use such amount as a foreign tax credit against federal income tax (but not both). A shareholder's ability to claim an offsetting foreign tax credit or deduction in respect of foreign taxes paid by the Fund is subject to certain limitations imposed by the Code, which may result in the shareholder's not receiving a full credit or deduction (if any) for the amount of such taxes. Shareholders who do not itemize on their U.S. federal income tax returns may claim a credit (but not a deduction) for such foreign taxes. It is anticipated that the Fund will qualify to make such election; however, the Fund cannot be certain that it will be eligible to make such an election for a given year. Even if the Fund were eligible to make such an election for a given year, it may determine not to do so. Shareholders that are not subject to U.S. federal income tax, and those who invest in the Fund through tax-advantaged accounts (including those who invest through individual retirement accounts or other tax-advantaged retirement plans), generally will receive no benefit from any tax credit or deduction passed through by the Fund.

In addition, a Fund's investments in foreign securities may be subject to special tax rules that have the effect of increasing or accelerating the Fund's recognition of ordinary income and may affect the timing or amount of the Fund's distributions.

**Backup Withholding.** The Fund is required in certain circumstances to withhold on taxable dividends, redemption proceeds and certain other payments that are paid to any shareholder (including a shareholder who is neither a citizen nor a resident of the United States) if the shareholder does not furnish the Fund with certain information and certifications or the shareholder is otherwise subject to backup withholding.

**Foreign Investors.** The Fund, which is offered for sale in the United States, is not widely available outside the United States. The Fund received U.K. filing status on April 19, 2022 and, as such, certain investors located outside of the United States will be permitted to invest in the Fund. Non-U.S. investors should be aware that U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investment in the Fund.

Foreign shareholders invested in the Fund should consult with their tax advisers as to if and how the U.S. federal income tax law and its withholding requirements apply to them. Generally, the Fund will withhold 30% (or lower applicable treaty rate) on distributions to foreign shareholders.

**Cost Basis Reporting.** The Internal Revenue Service ("IRS") requires the Fund to report to you and the IRS the cost basis and certain other related tax information on the sale of Fund shares acquired on or after January 1, 2012 ("covered shares"). If you acquire and hold shares directly through the Fund and not through a financial intermediary, the Fund will use an average cost single category methodology for tracking and reporting your cost basis on covered shares, unless you request, in writing, another cost basis reporting methodology. Please consult your tax adviser to determine which available cost basis method is best for you.

------

Special tax rules apply to investments through defined contribution plans and other tax-qualified plans or tax-advantaged arrangements. Shareholders should consult their tax advisers to determine the suitability of shares of the Fund as an investment through such plans and arrangements and the precise effect of an investment on their particular tax situation.

Please see the SAI for further information regarding certain U.S. federal income tax consequences of an investment in the Fund.

You should consult your tax adviser for more information on your own situation, including possible U.S. federal, state, local, foreign or other applicable taxes.

#### ACCOUNT POLICIES
**Important Notice Regarding Delivery of Shareholder Documents.** The Fund will send one copy of prospectuses and shareholder reports to households containing multiple shareholders with the same last name. This process, known as "householding," reduces costs and provides a convenience to shareholders. If you share the same last name and address with another shareholder and you prefer to receive separate prospectuses and shareholder reports, call the Fund at (800) 806-1112 (toll free) or (312) 557-3164 and we will begin separate mailings to you within 30 days of your request. If you or others in your household invest in the Fund through a broker or other financial intermediary, you may receive separate prospectuses and shareholder reports, regardless of whether or not you have consented to householding on your investment application.

**Notice Regarding Unclaimed Property.** It is important that the Fund maintains a correct address for each shareholder. An incorrect address may cause a shareholder's account statements and other mailings to be returned to the Fund. Based upon statutory requirements for returned mail, the Fund will attempt to locate the shareholder or rightful owner of the account. If the Fund is unable to locate the shareholder, then they will determine whether the shareholder's account can legally be considered abandoned. Your mutual fund account may be transferred to the state government of your state of residence if no activity occurs within your account during the "inactivity period" specified in your state's abandoned property laws. The Fund is legally obligated to escheat (or transfer) abandoned property to the appropriate state's unclaimed property administrator in accordance with statutory requirements. The shareholder's last known address of record determines which state has jurisdiction. Please proactively contact the Transfer Agent at (800) 806-1112 (toll free) or (312) 557-3164 at least annually to ensure your account remains in active status.

If you are a resident of the state of Texas, you may designate a representative to receive notifications that, due to inactivity, your mutual fund account assets may be delivered to the Texas Comptroller. Please contact the Transfer Agent if you wish to complete a Texas Designation of Representative form.
