Investment Objective

The Passport Overseas Equity Portfolio (the “Fund”) seeks long-term capital appreciation.

Fees and Expenses

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay fees other than the fees and expenses of the Fund, such as brokerage commissions and other fees charged by financial intermediaries, which are not reflected in the tables and examples below.

For purchases of Class A shares, you may qualify for a sales charge discount if the cumulative net asset value per share (“NAV”) of Class A shares of the Fund being purchased in a single transaction, together with the NAV of any shares of the Fund and any other Morgan Stanley Multi-Class Fund already held in Related Accounts (as defined in the section of the Prospectus entitled “Shareholder Information—Sales Charges Applicable to Purchases of Class A Shares”) as of the date of the transaction, amounts to $50,000 or more. For purposes of this calculation, holdings of the following Morgan Stanley Funds are excluded: Morgan Stanley Institutional Fund Trust Short Duration Income, Ultra-Short Income and Ultra-Short Municipal Income Portfolios (as defined in the section of the Prospectus entitled “Shareholder Information—Exchange Privilege”) and Morgan Stanley Money Market Funds (as defined in the section of the Prospectus entitled “Shareholder Information—Exchange Privilege”). Shares of Morgan Stanley Money Market Funds that you acquired in a prior exchange of shares of the Fund or shares of another Morgan Stanley Multi-Class Fund (other than Morgan Stanley Institutional Fund Trust Short Duration Income, Ultra-Short Income and Ultra-Short Municipal Income Portfolios) are included in the Class A share right of accumulation. More information about this combined purchase discount and other discounts is available from your authorized financial intermediary, on page 59 of the Prospectus in the section entitled “Shareholder Information—Sales Charges Applicable to Purchases of Class A Shares” and in Appendix A attached to the Prospectus.

Class I shares may be available on brokerage platforms of firms that have agreements with the Fund’s principal underwriter permitting such firms to (i) offer Class I shares solely when acting as an agent for the investor and (ii) impose on an investor transacting in Class I shares through such platforms a commission and/or other forms of compensation to the broker. Shares of the Fund are available in other share classes that have different fees and expenses.

Example

The example below 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, your investment has a 5% return each year and the Fund’s operating expenses remain the same (except that the example incorporates the fee waiver and/or expense reimbursement arrangement for only the first year). After eight years, Class C shares of the Fund generally will convert automatically to Class A shares of the Fund. The example for Class C shares reflects the conversion to Class A shares after eight years. Please refer to the section of the Prospectus entitled “Shareholder Information—Conversion Features” for more information. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


If You SOLD Your Shares
	1 Year	3 Years	5 Years	10 Years
Class I	$ 92	$ 326	$ 578	$ 1,301
Class A	$ 646	$ 919	$ 1,212	$ 2,046
Class L	$ 178	$ 582	$ 1,013	$ 2,210
Class C	$ 303	$ 739	$ 1,302	$ 2,539
Class R6	$ 87	$ 1,236	$ 2,374	$ 5,162


If You HELD Your Shares
	1 Year	3 Years	5 Years	10 Years
Class I	$ 92	$ 326	$ 578	$ 1,301
Class A	$ 646	$ 919	$ 1,212	$ 2,046
Class L	$ 178	$ 582	$ 1,013	$ 2,210
Class C	$ 203	$ 739	$ 1,302	$ 2,539
Class R6	$ 87	$ 1,236	$ 2,374	$ 5,162

Investments in Class A shares that are not subject to any sales charges at the time of purchase are subject to a contingent deferred sales charge (“CDSC”) of 1.00% that will be imposed if you sell your shares within 12 months, except for certain specific circumstances. See “Shareholder Information—How To Redeem Fund Shares” for further information about the CDSC waiver categories.

2	The Class C CDSC is only applicable if you sell your shares within one year after the last day of the month of purchase. See “Shareholder Information—How To Redeem Fund Shares” for a complete discussion of the CDSC.

The Fund’s “Adviser,” Morgan Stanley Investment Management Inc., has agreed to reduce its advisory fee and/or reimburse the Fund so that Total Annual Fund Operating Expenses, excluding acquired fund fees and expenses (as applicable), certain investment related expenses, taxes, interest and other extraordinary expenses (including litigation), will not exceed 0.90% for Class I, 1.25% for Class A, 1.75% for Class L, 2.00% for Class C and 0.85% for Class R6. The fee waivers and/or expense reimbursements will continue for at least one year from the date of this Prospectus or until such time as the Board of Directors of Morgan Stanley Institutional Fund, Inc. (the “Company”) acts to discontinue all or a portion of such waivers and/or reimbursements when it deems such action is appropriate.

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

Principal Investment Strategies

The Adviser actively selects among developed and emerging countries applying its investment process to determine a country’s future economic growth and equity return potential. The Adviser’s approach combines a top-down country process with sector allocation and bottom-up stock selection. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in the equity securities of issuers located outside of the United States. This policy may be changed without shareholder approval; however, you would be notified upon 60 days’ notice in writing of any changes.

The Adviser analyzes the global economic environment and each country’s fundamentals and actively allocate the Fund’s assets among countries and sectors located throughout the world (the investment universe is developed markets, including the United States, and emerging markets, including frontier markets). Investment decisions may be implemented through sector, industry and stock-specific allocations within and across markets that best capture the top-down view. Country and sector weightings are based on relative economic, political and social fundamentals, stock valuations and investor sentiment and are a function of the Adviser’s conviction levels, the size of the economy and liquidity. The investment process considers analysis of sustainability with respect to financial strength, environmental and social factors and governance (also referred to as ESG).

Investments are based on fundamental analysis in an effort to identify those equities that stand to benefit most from the Adviser’s current and prospective macro views and that are likely to experience attractive earnings growth prospects as a result of exposure and gearing to those top-down conditions. Investment decisions are implemented by equity positions in sectors, industries, customized baskets and/or individual stocks. The equity securities in which the Fund may invest include common stock, preferred stock, convertible securities, depositary receipts, rights and warrants. The Adviser generally considers selling a portfolio holding when they determine that the position no longer satisfies their investment criteria.

utilize foreign currency forward exchange contracts, which are also derivatives, in connection with its investments in foreign securities. Derivative instruments used by the Fund will be counted toward the Fund’s 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

Principal Risks

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. The principal risks of investing in the Fund include:

•

Equity Securities. In general, prices of equity securities are more volatile than those of fixed-income securities. The prices of equity securities fluctuate, and sometimes widely fluctuate, in response to activities specific to the issuer of the security as well as factors unrelated to the fundamental condition of the issuer, including general market, economic, political conditions and public health conditions. To the extent that the Fund invests in convertible securities, and the convertible security’s investment value is greater than its conversion value, its price will be likely to increase when interest rates fall and decrease when interest rates rise. If the conversion value exceeds the investment value, the price of the convertible security will tend to fluctuate directly with the price of the underlying security. During periods when equity securities experience heightened volatility, such as during periods of market, economic or financial uncertainty or distress, the Fund’s investments in equity securities may be subject to heightened risks.

•

Foreign and Emerging Market Securities. Investments in foreign markets entail special risks such as currency, political (including geopolitical), economic and market risks. There also may be greater market volatility, less reliable financial information, less stringent investor protections and disclosure standards, higher transaction and custody costs, decreased market liquidity and less government and exchange regulation associated with investments in foreign markets. In addition, investments in certain foreign markets that have historically been considered stable may become more volatile and subject to increased risk due to ongoing developments and changing conditions in such markets. Moreover, the growing interconnectivity of global economies and financial markets has increased the probability that adverse developments and conditions in one country or region will affect the stability of economies and financial markets in other countries or regions. Certain foreign markets may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments, the imposition of economic sanctions against a particular country or countries, organizations, companies, entities and/or individuals, changes in international trading patterns, trade barriers and other protectionist or retaliatory measures. Investments in foreign markets may also be adversely affected by governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. The governments of certain countries may prohibit or impose substantial restrictions on foreign investing in their capital markets or in certain sectors or industries. In addition, a foreign government may limit or cause delay in the convertibility or repatriation of its currency which would adversely affect the U.S. dollar value and/or liquidity of investments denominated in that currency. Certain foreign investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, its portfolio may be harder to value. The risks of investing in emerging market countries are greater than the risks associated with investments in foreign developed countries. Certain emerging market countries may be subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping and therefore, material information related to an investment may not be available or reliable. In addition, the Fund is limited in its ability to exercise its legal rights or enforce a counterparty’s legal obligations in certain jurisdictions outside of the United States, in particular, in emerging market countries. In addition, the Fund’s investments in foreign issuers may be denominated in foreign currencies and therefore, to the extent unhedged, the value of those investments will fluctuate with U.S. dollar exchange rates. To the extent hedged by the use of foreign currency forward exchange contracts, the precise matching of the foreign currency forward exchange contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. There is additional risk that such transactions may reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken and that foreign currency forward exchange contracts create exposure to currencies in which the Fund’s securities are not denominated. The use of foreign currency forward exchange contracts involves the risk of loss from the insolvency or bankruptcy of the counterparty to the contract or the failure of the counterparty to make payments or otherwise comply with the terms of the contract. Economic sanctions or other similar measures may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and other similar measures could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell securities, negatively impact the value or liquidity of the Fund’s investments, significantly delay or prevent the settlement of the Fund’s securities transactions, force the Fund to sell or otherwise dispose of investments at inopportune times or prices, or impair the Fund’s ability to meet its investment objective or invest in accordance with its investment strategies.

company, but in many cases these arrangements have not been tested in court and it is not clear that the contracts are enforceable or that the structures will otherwise work as intended. The offshore holding company, which is not a Chinese operating company, then issues exchange-traded shares that are sold to the public, including non-Chinese investors (such as the Fund). Shares of the offshore entity purchased by the Fund would not be equity ownership interests in the Chinese operating company and the Fund’s interest would be subject to legal, operational and other risks associated with the company’s use of the VIE structure. For example, at any time the Chinese government could determine that the contractual arrangements constituting part of the VIE structure are unenforceable or do not comply with applicable law or regulations, these laws or regulations could change or be interpreted differently in the future, and the Chinese government may with no advance notice otherwise intervene in or exert influence over VIE structures or the related Chinese operating companies. If any of these or similar risks or developments materialize, the Fund’s investment in the offshore entity may suddenly and significantly decline in value or become worthless because of, among other things, difficulty enforcing (or the inability to enforce) the contractual arrangements or materially adverse effects on the Chinse operating company’s performance. In these circumstances, the Fund could experience significant losses with no recourse available. From time to time, the Fund’s investments in U.S.-listed shell companies relying on VIE structures to consolidate China-based operations could be significant.

•

Liquidity. The Fund may make investments that are illiquid or restricted or that may become illiquid or less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.

•

Derivatives. Derivatives and other similar instruments often have risks similar to those of the underlying asset or instrument, including market risk, and may have additional risks, including imperfect correlation between the value of the derivative and the underlying asset, risks of default by the counterparty to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative instrument relates, risks that the transactions may not be liquid, risks arising from margin and payment requirements, risks arising from mispricing or valuation complexity and operational and legal risks. Certain derivative transactions may give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss.

•

Market and Geopolitical Risk. The value of your investment in the Fund is based on the values of the Fund’s investments, which may change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. These events may be sudden and unexpected, and could adversely affect the liquidity of the Fund’s investments, which may in turn impact valuation, the Fund’s ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other conditions and events (such as war, natural disasters, epidemics and pandemics, terrorism, conflicts, social unrest, recessions, inflation, rapid interest rate changes and supply chain disruptions) adversely interrupt the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance of the Fund’s investments, adversely affect and increase the volatility of the Fund’s share price and exacerbate pre-existing risks to the Fund.

•

Active Management Risk. In pursuing the Fund’s investment objective, the Adviser has considerable leeway in deciding which investments to buy, hold or sell on a day-to-day basis, and which trading strategies to use. For example, the Adviser, in its discretion, may determine to use some permitted trading strategies while not using others. The success or failure of such decisions will affect the Fund’s performance.

Shares of the Fund are not bank deposits and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The MSCI All Country World ex USA Index is a free float-adjusted market capitalization weighted index designed to measure the equity market performance of developed and emerging markets, excluding the United States. The term “free float” represents the portion of shares outstanding that are deemed to be available for purchase in the public equity markets by investors. The performance of the index is listed in U.S. dollars and assumes reinvestment of net dividends. Returns, including periods prior to January 1, 2001, are calculated using the return data of the MSCI All Country World ex USA Index (gross dividends) through December 31, 2000 and the return data of the MSCI All Country World ex USA Index (net dividends) after December 31, 2000. Net total return indices reinvest dividends after the deduction of withholding taxes, using (for international indices) a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties. It is not possible to invest directly in an index.

The Active International Allocation Blend Index is a performance linked benchmark of the old and new benchmark of the Fund, the old benchmark represented by MSCI EAFE Index (index that is designed to measure the international equity market performance of developed markets, excluding the United States and Canada) from the Fund’s inception to December 31, 2016 and the new benchmark represented by MSCI All Country World ex USA Index for periods thereafter. It is not possible to invest directly in an index.

Actual after-tax returns depend on the investor’s tax situation and may differ from those shown, and after-tax returns are not relevant to investors who hold their Fund shares through tax deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns may be higher than before-tax returns due to an assumed benefit from capital losses that would have been realized had Fund shares been sold at the end of the relevant periods, as applicable.

Purchase and Sale of Fund Shares

The Company has suspended offering Class L shares of the Fund for sale to all investors. The Class L shareholders of the Fund do not have the option of purchasing additional Class L shares. However, the existing Class L shareholders may invest in additional Class L shares through reinvestment of dividends and distributions.

The minimum initial investment generally is $1 million for Class I shares and $1,000 for each of Class A and Class C shares of the Fund. To purchase Class R6 shares, an investor must meet a minimum initial investment of $5 million or be a defined contribution, defined benefit or other employer sponsored employee benefit plan, in each case provided that the plan trades through an intermediary that combines its clients’ assets in a single omnibus account, whether or not such plan is qualified under the Internal Revenue Code of 1986, as amended (the “Code”), and in each case subject to the discretion of the Adviser. The minimum initial investment may be waived for certain investments. For more information, please refer to the section of the Prospectus entitled “Shareholder Information—Minimum Investment Amounts.”

Shares of the Fund may be purchased or sold on any day the New York Stock Exchange (“NYSE”) is open for business directly from the Fund by mail (c/o SS&C Global Investor and Distribution Solutions, Inc., P.O. Box 219804, Kansas City, MO 64121-9804), by telephone (1-800-869-6397) or by contacting an authorized third-party, such as a broker-dealer or other financial intermediary that has entered into a selling agreement with the Fund’s “Distributor,” Morgan Stanley Distribution, Inc. (each, a “Financial Intermediary”). In addition, you can sell Fund shares at any time by enrolling in a systematic withdrawal plan. If you sell Class A shares or Class C shares, your net sale proceeds are reduced by the amount of any applicable CDSC. For more information, please refer to the sections of the Prospectus entitled “Shareholder Information—How To Purchase Fund Shares” and “—How To Redeem Fund Shares.”

Tax Information

The Fund intends to make distributions that may be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a Financial Intermediary (such as a bank), the Adviser and/or the Distributor may pay the Financial Intermediary for the sale of Fund shares and related services. These payments, which may be significant in amount, may create a conflict of interest by influencing the Financial Intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your Financial Intermediary’s web site for more information.

Investment Objective

The Emerging Markets Leaders Portfolio (the “Fund”) seeks long-term capital appreciation.

Fees and Expenses

For purchases of Class A shares, you may qualify for a sales charge discount if the cumulative net asset value per share (“NAV”) of Class A shares of the Fund being purchased in a single transaction, together with the NAV of any shares of the Fund and any other Morgan Stanley Multi-Class Fund already held in Related Accounts (as defined in the section of the Prospectus entitled “Shareholder Information—Sales Charges Applicable to Purchases of Class A Shares”) as of the date of the transaction, amounts to $50,000 or more.

Principal Investment Strategies

The Adviser and the Fund’s “Sub-Adviser,” Morgan Stanley Investment Management Company (“MSIM Company”), seek to achieve the Fund’s investment objective by investing primarily in equity securities of companies located in emerging market countries.

The Adviser and/or Sub-Adviser generally use a fundamental bottom-up stock selection process informed by macro thematic research on overall emerging markets. The Adviser and/or Sub-Adviser will employ this consistent and targeted approach seeking companies they expect to become leading companies in emerging markets as well as developed country domiciled companies where a large portion of the companies’ growth is taking place in emerging market countries. The Adviser and/or Sub-Adviser seek to construct a focused portfolio of equity securities designed to take advantage of thematic opportunities in emerging markets by seeking to invest in companies that they believe have the potential to outperform emerging markets generally over the long-term.

The investment process takes into account information about environmental, social and governance issues (also referred to as ESG) when making investment decisions. The Adviser and/or Sub-Adviser focus on engaging company management around corporate governance practices as well as what the Adviser and/or Sub-Adviser deem to be materially important environmental and/or social issues facing a company. The investment process excludes holdings in tobacco companies.

Under normal circumstances, at least 80% of the Fund’s assets will be invested in equity securities of issuers located in emerging market countries. This policy may be changed without shareholder approval; however, you would be notified upon 60 days’ notice in writing of any changes. The Adviser and/or Sub-Adviser generally consider selling an investment when they determine the company no longer satisfies their investment criteria.

have exposure to equity securities of companies of any size, including small and medium capitalization companies, and to companies in any industry or sector.

For purposes of maintaining exposure of at least 80% of the Fund’s assets to equity securities of companies located in emerging market countries, the Fund may also invest in American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and other types of depositary receipts with respect to companies located in emerging market countries.

The Fund may, but it is not required to, use derivative instruments for a variety of purposes, including hedging, risk management, portfolio management or to earn income. The Fund’s use of derivatives may involve the purchase and sale of derivative instruments such as options, futures, swaps, contracts for difference (“CFDs”), structured investments and other related instruments and techniques. The Fund may utilize foreign currency forward exchange contracts, which are also derivatives, in connection with its investments in foreign securities. Derivative instruments used by the Fund will be counted toward the Fund’s 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

Principal Risks

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. The principal risks of investing in the Fund include:

•

restrict or eliminate the Fund’s ability to purchase or sell securities, negatively impact the value or liquidity of the Fund’s investments, significantly delay or prevent the settlement of the Fund’s securities transactions, force the Fund to sell or otherwise dispose of investments at inopportune times or prices, or impair the Fund’s ability to meet its investment objective or invest in accordance with its investment strategies.

•

China Risk. Investments in securities of Chinese issuers, including A shares, involve risks associated with investments in foreign markets as well as special considerations not typically associated with investments in the U.S. securities markets. For example, the Chinese government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, the Chinese government has taken actions that influenced the prices at which certain goods may be sold, encouraged companies to invest or concentrate in particular industries, induced mergers between companies in certain industries and induced private companies to publicly offer their securities. Investments in China involve risk of a total loss due to government action or inaction. Additionally, the Chinese economy is export-driven and highly reliant on trade. Adverse changes to the economic conditions of its primary trading partners, such as the United States, Japan and South Korea, would adversely impact the Chinese economy and the Fund’s investments. Moreover, a slowdown in other significant economies of the world, such as the United States, the European Union and certain Asian countries, may adversely affect economic growth in China. An economic downturn in China would adversely impact the Fund’s investments. In addition, certain securities are, or may in the future, become restricted, and/or sanctioned by the U.S. government or other governments and the Fund may be forced to sell such restricted securities and incur a loss as a result.

These and other developments, including government actions, may result in significant illiquidity risk or forced disposition for Chinese investments. The Chinese securities markets are emerging markets characterized by a relatively small number of equity issues and relatively low trading volume, resulting in decreased liquidity, greater price volatility (caused by, among other things, military, diplomatic, or trade conflicts), and potentially fewer investment opportunities for the Fund. Ongoing political tension between the People’s Republic of China and the Hong Kong Special Administrative Region may have impacts on the economy of Hong Kong, and these impacts remain uncertain.

Risks of Investing through Stock Connect. The Fund may invest in A-shares listed and traded through Stock Connect, or on such other stock exchanges in China which participate in Stock Connect from time to time or in the future. Trading through Stock Connect is subject to a number of restrictions that may affect the Fund’s investments and returns. Moreover, Stock Connect A-shares generally may not be sold, purchased or otherwise transferred other than through Stock Connect in accordance with applicable rules. The Stock Connect program is a relatively new program and may be subject to further interpretation and guidance. There can be no assurance as to the program’s continued existence or whether future developments regarding the program may restrict or adversely affect the Fund’s investments or returns. Because certain transactions through Stock Connect may not be subject to certain investor protection programs, the Fund may be exposed to the risks of default of the broker(s) they engage in their trading in China A Shares.

Variable Interest Entities. Chinese operating companies sometimes rely on variable interest entity (“VIE”) structures to raise capital from non-Chinese investors because of Chinese government limitations or prohibitions on direct foreign ownership in certain industries. In a VIE structure, a series of contractual arrangements are entered into between a holding company domiciled outside of China and a Chinese operating company or companies, which are intended to mimic direct ownership in the operating company, but in many cases these arrangements have not been tested in court and it is not clear that the contracts are enforceable or that the structures will otherwise work as intended. The offshore holding company, which is not a Chinese operating company, then issues exchange-traded shares that are sold to the public, including non-Chinese investors (such as the Fund). Shares of the offshore entity purchased by the Fund would not be equity ownership interests in the Chinese operating company and the Fund’s interest would be subject to legal, operational and other risks associated with the company’s use of the VIE structure. For example, at any time the Chinese government could determine that the contractual arrangements constituting part of the VIE structure are unenforceable or do not comply with applicable law or regulations, these laws or regulations could change or be interpreted differently in the future, and the Chinese government may with no advance notice otherwise intervene in or exert influence over VIE structures or the related Chinese operating companies. If any of these or similar risks or developments materialize, the Fund’s investment in the offshore entity may suddenly and significantly decline in value or become worthless because of, among other things, difficulty enforcing (or the inability to enforce) the contractual arrangements or materially adverse effects on the Chinse operating company’s performance. In these circumstances, the Fund could experience significant losses with no recourse available. From time to time, the Fund’s investments in U.S.-listed shell companies relying on VIE structures to consolidate China-based operations could be significant.

•

Small and Mid Cap Companies. Investments in small and mid cap companies may involve greater risks than investments in larger, more established companies. The securities issued by small and mid cap companies may be less liquid and such companies may have more limited markets, financial resources and product lines, and may lack the depth of management of larger companies.

•	Liquidity. The Fund may make investments that are illiquid or restricted or that may become illiquid or less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of

securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.

•

Non-Diversification. The Fund is non-diversified, which means that the Fund may invest a greater percentage of its assets in a smaller number of issuers than a diversified fund. Because the Fund is non-diversified, it may be more susceptible to an adverse event affecting a single issuer or portfolio investment than a diversified portfolio and a decline in the value of that issuer’s securities or that portfolio investment may cause the Fund’s overall value to decline to a greater degree than a diversified portfolio.

•

Shares of the Fund are not bank deposits and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Pursuant to an agreement and plan of reorganization, between the Company, on behalf of the Fund, and Morgan Stanley Emerging Markets Leaders Fund (Cayman) LP, a private fund managed by the Adviser (the “Private Fund”), at open of business on January 6, 2015, the Fund acquired substantially all of the assets and liabilities of the Private Fund in exchange for shares of the Fund (the “Emerging Markets Leaders Reorganization”). The Private Fund commenced operations on June 30, 2011, and had an investment objective, policies, and strategies that were, in all material respects, the same as those of the Fund, and was managed in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Fund. However, the Private Fund was not registered as an investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), and therefore was not subject to certain investment limitations, diversification requirements, liquidity requirements, and other restrictions imposed by the 1940 Act and the Internal Revenue Code of 1986, as amended (the “Code”), which, if applicable, may have adversely affected its performance.

The Fund adopted the performance history of the Private Fund. As a result, the historical performance information shown below reflects, for the periods prior to the Emerging Markets Leaders Reorganization, the historical performance of the Private Fund. The performance of the Private Fund has been restated to reflect any applicable sales charge but is otherwise not adjusted to reflect differences in expenses between the Private Fund and each class, as applicable.

The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s Class I shares’ performance from year-to-year and by showing how the Fund’s average annual returns for the past one, five and 10 year periods and since inception compare with those of a broad measure of market performance, as well as an index that represents a group of similar mutual funds, over time. The performance of the other classes, which is shown in the table below, will differ because the classes have different ongoing fees. The Fund’s returns in the table include the maximum applicable sales charge for Class A and Class C and assume you sold your shares at the end of each period (unless otherwise noted). The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

Performance shown for the Fund’s Class I, Class A and Class R6 shares reflects the performance of the limited partnership interests of the Private Fund for periods prior to the Emerging Markets Leaders Reorganization, adjusted to reflect any applicable sales charge of the class, but not adjusted for any other differences in expenses. If adjusted for other expenses, returns would be different.

2	These returns do not reflect any tax consequences from a sale of your shares at the end of each period.

The MSCI Emerging Markets Net Index is a free float-adjusted market capitalization weighted index that is designed to measure equity market performance of emerging markets. The term “free float” represents the portion of shares outstanding that are deemed to be available for purchase in the public equity markets by investors. The MSCI Emerging Markets Net Index currently consists of 24 emerging market country indices. The performance of the index is listed in U.S. dollars and assumes reinvestment of net dividends. Net total return indices reinvest dividends after the deduction of withholding taxes, using (for international indices) a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties. It is not possible to invest directly in an index.

4	Since Inception reflects the inception date of Class I.

5	The Lipper Emerging Markets Funds Index is an equally-weighted performance index of the largest qualifying funds (based on net assets) in the Lipper Emerging Markets Funds classification. There are currently 30 funds represented in this index.

The after-tax returns shown in the table above are calculated using the historical highest individual federal marginal income tax rates during the period shown and do not reflect the impact of state and local taxes. After-tax returns for the Fund’s other classes will vary from Class I shares’ returns. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown, and after-tax returns are not relevant to investors who hold their Fund shares through tax deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns may be higher than before-tax returns due to foreign tax credits and/or an assumed benefit from capital losses that would have been realized had Fund shares been sold at the end of the relevant periods, as applicable.

Portfolio Turnover

Principal Investment Strategies

The Adviser and the Fund’s “Sub-Adviser,” Morgan Stanley Investment Management Company (“MSIM Company”), seek to maximize returns by investing primarily in quality growth-oriented equity securities in emerging markets.

The Adviser’s and/or Sub-Adviser’s investment approach combines top-down country and thematic allocation with bottom-up stock selection. The Adviser and/or Sub-Adviser allocate the Fund’s assets among emerging markets based on relative economic, political and social fundamentals, stock valuations and investor sentiment. To manage risk, the Adviser and/or Sub-Adviser emphasize macroeconomic and fundamental research.

The investment process integrates information about environmental, social and governance issues (also referred to as ESG) when making investment decisions. The Adviser and/or Sub-Adviser believe that monitoring ESG helps build a more complete picture of the opportunities and risks facing companies, and seeks to engage directly with company management to gain insights on how each company addresses material ESG issues and how these may affect long-term financial performance.

The Fund may, but it is not required to, use derivatives and similar instruments for a variety of purposes, including hedging, risk management, portfolio management or to earn income. The Fund’s use of derivatives may involve the purchase and sale of derivative

instruments such as futures and other similar instruments and techniques. The Fund may utilize foreign currency forward exchange contracts, which are also derivatives, in connection with its investments in foreign securities. Derivative instruments used by the Fund will be counted toward the Fund’s 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

Principal Risks

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. The principal risks of investing in the Fund include:

•

Foreign Currency. The Fund’s investments in foreign securities may be denominated in foreign currencies. The value of foreign currencies may fluctuate relative to the value of the U.S. dollar. Since the Fund may invest in such non-U.S. dollar-denominated securities, and therefore may convert the value of such securities into U.S. dollars, changes in currency exchange rates can increase or decrease the U.S. dollar value of the Fund’s assets. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the overall economic health of the issuer. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. The Adviser may use derivatives to reduce this risk. The Adviser may in its discretion choose not to

hedge against currency risk. In addition, certain market conditions may make it impossible or uneconomical to hedge against currency risk.

•

India Risk. To the extent that the Fund invests a substantial portion of its assets in Indian issuers, the value of the Fund’s assets may be adversely affected by political, economic, social and religious factors impacting Indian businesses and the Indian economy, changes in Indian law or regulations and the status of India’s relations with other countries. Indian government actions in the future could have a significant effect on the Indian economy, which could affect private sector companies and the Fund, market conditions, and prices and yields of securities in the Fund’s portfolio. To the extent the Fund invests a significant portion of its assets in Indian businesses and the Indian economy, factors that have an adverse impact on Indian businesses and the Indian economy may have a disproportionate impact on the Fund’s performance.

•

Shares of the Fund are not bank deposits and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s Class I shares’ performance from year-to-year and by showing how the Fund’s average annual returns for the past one, five and 10 year periods and since inception compare with those of a broad measure of market performance, as well as an index that represents a group of similar mutual funds, over time. The performance of the other classes, which is shown in the table below, will differ because the classes have different ongoing fees. The Fund’s returns in the table include the maximum applicable sales charge for Class A and Class C and assume you sold your shares at the end of each period (unless otherwise noted).

The MSCI Emerging Markets Index is a free float-adjusted market capitalization weighted index that is designed to measure equity market performance of emerging markets. The term “free float” represents the portion of shares outstanding that are deemed to be available for purchase in the public equity markets by investors. The MSCI Emerging Markets Index currently consists of 24 emerging market country indices. The performance of the index is listed in U.S. dollars and assumes reinvestment of net dividends. Returns, including periods prior to January 1, 2001, are calculated using the return data of the MSCI Emerging Markets Index (gross dividends) through December 31, 2000 and the return data of the MSCI Emerging Markets Net Index (net dividends) after December 31, 2000. Net total return indices reinvest dividends after the deduction of withholding taxes, using (for international indices) a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties. It is not possible to invest directly in an index.

Investments in Class A shares that are not subject to any sales charges at the time of purchase are subject to a contingent deferred sales charge (“CDSC”) of 1.00% that will be imposed if you sell your shares within 12 months after purchase, except for certain specific circumstances. See “Shareholder Information—How To Redeem Fund Shares” for further information about the CDSC waiver categories.

2	The Class C CDSC is only applicable if you sell your shares within one year after the last day of the month of purchase. See “Shareholder Information—How To Redeem Fund Shares” for a complete discussion of the CDSC.

The Fund’s “Adviser,” Morgan Stanley Investment Management Inc., has agreed to reduce its advisory fee and/or reimburse the Fund so that Total Annual Fund Operating Expenses, excluding acquired fund fees and expenses (as applicable), certain investment related expenses, taxes, interest and other extraordinary expenses (including litigation), will not exceed 1.25% for Class I, 1.60% for Class A, 2.10% for Class L, 2.35% for Class C and 1.20% for Class R6. The fee waivers and/or expense reimbursements will continue for at least one year from the date of this Prospectus or until such time as the Board of Directors of Morgan Stanley Institutional Fund, Inc. (the “Company”) acts to discontinue all or a portion of such waivers and/or reimbursements when it deems such action is appropriate.

Principal Investment Strategies

The Fund’s Adviser seeks to achieve the Fund’s investment objective by investing primarily in growth-oriented equity securities in emerging markets, which include frontier emerging markets.

The Adviser’s investment approach combines top-down macro and thematic allocation with bottom-up stock selection. The Adviser allocates the Fund’s assets among emerging markets, including frontier emerging markets, based on relative economic, political and social fundamentals, market valuations and investor sentiment. To manage risk, the Adviser emphasizes macroeconomic and fundamental research.

The investment process integrates information about environmental, social and governance issues (also referred to as ESG) when making investment decisions. The Adviser believes that monitoring ESG helps build a more complete picture of the opportunities and risks facing companies, and seeks to engage directly with company management to gain insights on how each company addresses material ESG issues and how these may affect long-term financial performance. The investment process excludes holdings in tobacco companies.

Under normal circumstances, at least 80% of the Fund’s assets will be invested in equity securities of companies operating in emerging market countries, which include frontier emerging market countries. This policy may be changed without shareholder approval; however, you would be notified upon 60 days’ notice in writing of any changes. Emerging market or developing countries are countries that major international financial institutions or the MSCI Emerging Markets Net Index generally consider to be less economically mature than developed nations, such as the United States or most nations in Western Europe. Emerging market or developing countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe.

The equity securities in which the Fund may primarily invest include common and preferred stocks, convertible securities, rights, warrants, depositary receipts, limited partnership interests and other specialty securities having equity features. The Fund may hold or have exposure to equity securities of companies of any size, including small and medium capitalization companies, and to companies

in any industry or sector. The Adviser generally considers selling a portfolio holding when it determines that the holding no longer satisfies its investment criteria.

The Fund invests primarily in equity securities of companies operating in frontier emerging market countries. The term “frontier emerging markets” refers to those emerging market countries outside the “mainstream” emerging markets, whose capital markets have traditionally been difficult for foreign investors to enter or are in early stages of capital market and/or economic development. Frontier emerging market countries include, among others, Albania, Algeria, Argentina, Bahrain, Bangladesh, Bolivia, Botswana, Brazil, Bulgaria, Chile, Colombia, Costa Rica, Cote d’Ivoire, Croatia, Czech Republic, Dominican Republic, Ecuador, Egypt, Estonia, Ethiopia, Georgia, Ghana, Greece, Guatemala, Guinea, Haiti, Honduras, Hungary, Iceland, Indonesia, Jamaica, Jordan, Kazakhstan, Kenya, Kuwait, Laos, Latvia, Lebanon, Lithuania, Malaysia, Mauritius, Mexico, Mongolia, Morocco, Mozambique, Namibia, Nigeria, Oman, Pakistan, Panama, Paraguay, Peru, Poland, Philippines, Qatar, Romania, Russia, Rwanda, Saudi Arabia, Serbia, Senegal, Slovenia, Slovakia, South Africa, Sri Lanka, Tanzania, Trinidad & Tobago, Thailand, Turkey, Turkmenistan, Ukraine, United Arab Emirates, Uganda, Uruguay, Uzbekistan, Vietnam, and Zambia. The countries within the “frontier emerging markets” universe, as well as the countries in which the Fund invests, may change from time to time.

For purposes of maintaining exposure of at least 80% of the Fund’s assets to equity securities of companies operating in emerging market countries, which include frontier emerging market countries, the Fund may also invest in American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and other types of depositary receipts with respect to companies operating in emerging market countries, securities of other open- and closed-end investment companies, including exchange-traded funds (“ETFs”), and derivative instruments as described herein.

The Fund may, but it is not required to, use derivative instruments for a variety of purposes, including hedging, risk management, portfolio management or to earn income. The Fund’s use of derivatives may involve the purchase and sale of derivative instruments such as futures, swaps, contracts for difference (“CFDs”), structured investments and other related instruments and techniques. The Fund may utilize foreign currency forward exchange contracts, which are also derivatives, in connection with its investments in foreign securities. Derivative instruments used by the Fund will be counted toward the Fund’s 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

Principal Risks

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. The principal risks of investing in the Fund include:

•

therefore, material information related to an investment may not be available or reliable. In addition, the Fund is limited in its ability to exercise its legal rights or enforce a counterparty’s legal obligations in certain jurisdictions outside of the United States, in particular, in emerging market countries. In addition, the Fund’s investments in foreign issuers may be denominated in foreign currencies and therefore, to the extent unhedged, the value of those investments will fluctuate with U.S. dollar exchange rates. To the extent hedged by the use of foreign currency forward exchange contracts, the precise matching of the foreign currency forward exchange contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. There is additional risk that such transactions may reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken and that foreign currency forward exchange contracts create exposure to currencies in which the Fund’s securities are not denominated. The use of foreign currency forward exchange contracts involves the risk of loss from the insolvency or bankruptcy of the counterparty to the contract or the failure of the counterparty to make payments or otherwise comply with the terms of the contract. Economic sanctions or other similar measures may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and other similar measures could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell securities, negatively impact the value or liquidity of the Fund’s investments, significantly delay or prevent the settlement of the Fund’s securities transactions, force the Fund to sell or otherwise dispose of investments at inopportune times or prices, or impair the Fund’s ability to meet its investment objective or invest in accordance with its investment strategies.

•

Frontier Emerging Market Securities. Investing in the securities of issuers operating in frontier emerging markets involves a high degree of risk and special considerations not typically associated with investing in the securities of other foreign or U.S. issuers. In addition, the risks associated with investing in the securities of issuers operating in emerging market countries are magnified when investing in frontier emerging market countries. These types of investments could be affected by factors not usually associated with investments in U.S. issuers, including risks associated with expropriation and/or nationalization, political or social instability, pervasiveness of corruption and crime, armed conflict, the impact on the economy of civil war, religious or ethnic unrest and the withdrawal or non-renewal of any license enabling the Fund to trade in securities of a particular country, confiscatory taxation, restrictions on transfers of assets, lack of uniform accounting, auditing and financial reporting standards, less publicly available financial and other information, less stringent investor protections and disclosure standards, diplomatic development which could affect U.S. investments in those countries and potential difficulties in enforcing contractual obligations. These risks and special considerations make investments in companies operating in frontier emerging market countries highly speculative in nature and, accordingly, an investment in the Fund must be viewed as highly speculative in nature and may not be suitable for an investor who is not able to afford the loss of his or her entire investment. To the extent that the Fund invests a significant percentage of its assets in a single frontier emerging market country, the Fund will be subject to heightened risk associated with investing in frontier emerging market countries and additional risks associated with that particular country. A government of a frontier emerging market country may limit or cause delay in the convertibility or repatriation of its currency and therefore could adversely affect the U.S. dollar value and/or liquidity of investments denominated in that currency. Certain foreign investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, its portfolio may be harder to value. From time to time, certain of the companies in which the Fund expects to invest may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. Government and the United Nations and/or countries identified by the U.S. Government as state sponsors of terrorism. A company may suffer damage to its reputation if it is identified as such a company and, as an investor in such companies, the Fund will be indirectly subject to those risks. Certain frontier market countries may be subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping and therefore, material information related to an investment may not be available or reliable. In addition, the Fund is limited in its ability to exercise its legal rights or enforce a counterparty’s legal obligations in certain jurisdictions outside of the United States, in particular, in frontier markets countries. In addition, a substantial portion of the Fund’s investments in foreign issuers may be denominated in foreign currencies and therefore, to the extent unhedged, the value of those investments will fluctuate with U.S. dollar exchange rates. To the extent hedged by the use of foreign currency forward exchange contracts, the precise matching of the foreign currency forward exchange contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. There is additional risk that such transactions could reduce or preclude the opportunity for gain if the value of the currency moves in the direction opposite to the position taken and that foreign currency forward exchange contracts create exposure to currencies in which the Fund’s securities are not denominated. The use of foreign currency forward exchange contracts involves the risk of loss from the insolvency or bankruptcy of the counterparty to the contract or the failure of the counterparty to make payments or otherwise comply with the terms of the contract. Economic sanctions may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and other similar governmental actions could, among other things, effectively

restrict or eliminate the Fund’s ability to purchase or sell securities or groups of securities, and thus may make the Fund’s investments in such securities less liquid or more difficult to value. In addition, as a result of economic sanctions, the Fund may be forced to sell or otherwise dispose of investments at inopportune times or prices.

•

Information Technology Sector. To the extent the Fund invests a substantial portion of its assets in the information technology sector, the value of Fund shares may be particularly impacted by events that adversely affect the information technology sector, such as rapid changes in technology product cycles, product obsolescence, government regulation, and competition, and may fluctuate more than that of a fund that does not invest significantly in companies in the technology sector.

•

Banking Industry. The banking industry can be affected by global and local economic conditions, such as the levels and liquidity of the global and local financial and asset markets, the absolute and relative level and volatility of interest rates and equity prices, investor sentiment, inflation, and the availability and cost of credit. Adverse developments in these conditions can have a greater adverse effect on the banking industry of a frontier emerging market economy than on other industries of its economy. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operations and profitability of the banking industry. To the extent the Fund invests a substantial portion of its assets in the banking industry, factors that have an adverse impact on this industry may have a disproportionate impact on the Fund’s performance.

•

Investment Company Securities. Subject to the limitations set forth in the 1940 Act, or as otherwise permitted by the SEC, the Fund may acquire shares in other investment companies, including foreign investment companies and ETFs, which may be managed by the Adviser or its affiliates. The market value of the shares of other investment companies may differ from the NAV of the Fund. The shares of closed-end investment companies frequently trade at a discount to their NAV. As a shareholder in an investment company, the Fund would bear its ratable share of that entity’s expenses, including its investment advisory and administration fees. At the same time, the Fund would continue to pay its own advisory and administration fees and other expenses. As a result, the Fund and its shareholders, in effect, will be absorbing duplicate levels of fees with respect to investments in other investment companies.

•

Shares of the Fund are not bank deposits and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Pursuant to an agreement and plan of reorganization between the Company, on behalf of the Fund, and Morgan Stanley Frontier Emerging Markets Fund, Inc. (the “Frontier Predecessor Fund”), on September 17, 2012 the Fund acquired all of the assets and liabilities of the Frontier Predecessor Fund in exchange for Class I shares of the Fund (the “Frontier Reorganization”). As a result of the Frontier Reorganization, the Fund is the accounting successor of the Frontier Predecessor Fund. The historical performance information shown below reflects, for the period prior to the Frontier Reorganization, the historical performance of the Frontier Predecessor Fund. The Frontier Predecessor Fund may have performed differently if it were an open-end fund since closed-end funds are generally not subject to the cash flow fluctuations of an open-end fund. The Fund changed its name from Frontier Emerging Markets Portfolio to Frontier Markets Portfolio effective March 31, 2017 and from Frontier Markets Portfolio to Next Gen Emerging Markets Portfolio effective June 30, 2021.

The bar chart and table on the following page provide some indication of the risks of investing in the Fund by showing changes in the Fund’s Class I shares’* performance from year-to-year and by showing how the Fund’s average annual returns for the past one, five and 10 year periods and since inception compare with those of a broad measure of market performance, as well as an index that represents a group of similar mutual funds, over time. The performance of the other classes, which is shown in the table below, will differ because the classes have different ongoing fees. The Fund’s returns in the table include the maximum applicable sales charge for Class A and Class C and assume you sold your shares at the end of each period (unless otherwise noted). The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

1	Performance shown for the Fund’s Class I shares reflects the performance of the common shares of the Frontier Predecessor Fund for periods prior to September 17, 2012.

2	These returns do not reflect any tax consequences from a sale of your shares at the end of each period.

The MSCI Frontier Emerging Markets Net Index is a free float-adjusted market capitalization index that is designed to measure equity market performance of frontier emerging markets. The MSCI Frontier Emerging Markets Index captures large and mid cap representation across 32 Frontier Emerging Markets countries. The performance of the index is listed in U.S. dollars and assumes reinvestment of net dividends. Net total return indices reinvest dividends after the deduction of withholding taxes, using (for international indices) a tax rate applicable to non-resident institutional investors who do not benefit from double taxation treaties. It is not possible to invest directly in an index.

4	Since Inception reflects the inception date of Class I.

The MSCI Frontier Markets/MSCI Frontier Emerging Markets Blend Index is a performance linked benchmark of the old and new benchmark of the Fund. The old benchmark represented by the MSCI Frontier Markets Net Index from the Fund’s inception to June 29, 2021 to the new benchmark represented by the MSCI Frontier Emerging Markets Net Index for periods thereafter. The performance of the Index is calculated in U.S. dollars and assumes reinvestment of net dividends. Net total return indices reinvest dividends after the deduction of withholding taxes, using (for international indices) a tax rate applicable to nonresident institutional investors who do not benefit from double taxation treaties. It is not possible to invest directly in an index.

6	The Lipper Emerging Markets Funds Index is an equally weighted performance index of the largest qualifying funds (based on net assets) in the Lipper Emerging Markets Funds classification. There are currently 30 funds represented in this Index.

The after-tax returns shown in the table above are calculated using the historical highest individual federal marginal income tax rates during the period shown and do not reflect the impact of state and local taxes. After-tax returns for the Fund’s other classes will vary from Class I shares’ returns. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown, and after-tax returns are not relevant to investors who hold their Fund shares through tax deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns may be higher than before-tax returns due to an assumed benefit from capital losses that would have been realized had Fund shares been sold at the end of the relevant periods, as applicable.
