Investment Objective

The Global Opportunity 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 Class IR shares of the Fund. The Fund does not charge any sales loads or other fees when you purchase or redeem Class IR shares. 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.

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


	Class IR
Advisory Fee¹	0.74%
Distribution and/or Shareholder Service (12b-1) Fee	None
Other Expenses²	0.12%
Total Annual Fund Operating Expenses	0.86%

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. 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 IR	$88	$274	$477	$1,061


If You HELD Your shares
	1 Year	3 Years	5 Years	10 Years
Class IR	$88	$274	$477	$1,061

“Advisory Fee” includes the management fee of a wholly-owned subsidiary of the Fund organized as a company under the laws of the Cayman Islands (the “Subsidiary”). The Fund’s “Adviser,” Morgan Stanley Investment Management Inc., has agreed to waive or credit a portion of the advisory fee in an amount equal to the management fee paid to the Adviser by the Subsidiary.

2	“Other Expenses” include expenses of the Fund’s and Subsidiary’s most recent fiscal year.

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 11% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Adviser seeks to achieve the Fund’s investment objective by investing primarily in established and emerging companies located throughout the world, with capitalizations within the range of companies included in the MSCI All Country World Index.

The Adviser emphasizes a bottom-up stock selection process, seeking attractive investments on an individual company basis. In selecting securities for investment, the Adviser seeks high quality established and emerging companies that the Adviser believes are undervalued at the time of purchase. Fundamental research drives the investment process. The Adviser typically favors companies it believes have sustainable competitive advantages that can be monetized through growth. The investment process integrates analysis of sustainability with respect to disruptive change, financial strength, environmental and social externalities and governance (also referred to as ESG). The Adviser typically focuses a significant portion of the Fund’s investments in a limited number of issuers, which may be in the same industry, sector or geographic region. The Adviser generally considers selling a portfolio holding when it determines that the holding no longer satisfies its investment criteria.

impact the risk and reward profile of investment opportunities, the Adviser typically engages company management in constructive discussions on a range of ESG issues the Adviser deems materially important.

The Fund may invest in China A-Shares (shares of publicly traded companies based in mainland China) listed and traded on the Shanghai Stock Exchange through the Shanghai-Hong Kong Stock Connect program, as well as China A-Shares listed and traded on the Shenzhen-Hong Kong Stock Connect program (collectively, “Stock Connect”).

The Fund may also invest in American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and other types of depositary receipts with respect to issuers located or operating outside of the United States. The Fund may invest in equity securities. The Fund may also invest in privately placed and restricted securities.

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. 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.

The value of equity securities and related instruments may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer- and sector-specific considerations; unexpected trading activity among retail investors; and other factors. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines, the value of Fund shares will also likely decline.

•

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.

•

Focused Investing. Although the Fund is a diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), the Fund typically invests a significant portion of its portfolio in a limited number of issuers, which may be in the same industry, sector or geographic region. As a result, the Fund will be more susceptible to risks associated with, and negative events affecting those issuers, industries, sectors or geographic regions, and a decline in the value of a particular instrument may cause the Fund’s overall value to be more volatile and decline to a greater degree than if the Fund were invested more widely.

•

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 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.

•

Market and Geopolitical Risk. The value of your investment in the Fund is based on the values of the Fund’s investments, which 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, 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.

•

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 and may be unable to sell the security at all.

•

Consumer Discretionary. To the extent that the Fund invests a substantial portion of its assets in the consumer discretionary sector, the Fund will be particularly susceptible to the risks associated with companies operating in such sector(s). Companies in the consumer discretionary sector are subject to risks, including fluctuations in the performance of the overall domestic and international economy, shipment and supply chain disruptions, interest rate changes, currency exchange rates, increased competition and consumer confidence. Performance of such companies may also be adversely affected by factors such as reduced disposable household income, reduced consumer spending, and changing demographics and consumer tastes.

•

Information Technology Sector Risk. 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.

•

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 Chinese 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.

•

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.

The MSCI All Country World Net Index is a free float-adjusted market capitalization weighted index designed to measure the equity market performance of developed and 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 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.

3	Since Inception reflects the inception date of Class IR.

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 IR 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.

sustainability with respect to disruptive change, financial strength, environmental and social externalities and governance (also referred to as ESG). The Adviser typically focuses a significant portion of the Fund’s investments in a limited number of issuers, which may be in the same industry, sector or geographic region. The Adviser generally considers selling a portfolio holding when it determines that the holding no longer satisfies its investment criteria.

The Adviser views incorporating ESG-related potential risks and opportunities within the investment process as important to ensure long-term stewardship of capital. Over extended time horizons, the Adviser believes that ESG risks are more likely to materialize and externalities not borne by the company are more likely to be priced into the value of securities. Since ESG risks could potentially impact the risk and reward profile of investment opportunities, the Adviser typically engages company management in constructive discussions on a range of ESG issues the Adviser deems materially important.

The Fund invests primarily in securities of companies located in Europe, Japan, Asia, the Pacific Basin, Latin America, the Middle East and Africa. The Fund may also invest in securities of companies located in the United States to a limited extent.

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:

•

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.

•

Financials Sector. To the extent the Fund invests a substantial portion of its assets in the financials sector, factors that have an adverse impact on this sector may have a disproportionate impact on the Fund’s performance. The financials sector 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 financials sector of an 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 financials sector.

•

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.

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.

Investment Objective

The Global Opportunity Portfolio seeks long-term capital appreciation.

The Fund’s investment objective may be changed by the Company’s Board of Directors without shareholder approval, but no change is anticipated. If the Fund’s investment objective changes, the Fund will notify shareholders and shareholders should consider whether the Fund remains an appropriate investment in light of the change.

Approach

Process

The Adviser emphasizes a bottom-up stock selection process, seeking attractive investments on an individual company basis. In selecting securities for investment, the Adviser seeks high quality established and emerging companies that the Adviser believes are undervalued at the time of purchase. The Adviser typically favors companies it believes have sustainable competitive advantages that can be monetized through growth. The investment process integrates analysis of sustainability with respect to disruptive change, financial strength, environmental and social externalities and governance (also referred to as ESG). The Adviser typically focuses a significant portion of the Fund’s investments in a limited number of issuers, which may be in the same industry, sector or geographic region. The Adviser generally considers selling a portfolio holding when it determines that the holding no longer satisfies its investment criteria.

Fundamental research drives the investment process. The Adviser studies on an ongoing basis company developments, including business strategy and financial results.

The Fund may also invest in ADRs, GDRs and other types of depositary receipts with respect to issuers located or operating outside of the United States.

The Fund may invest in equity securities. The Fund may also invest in privately placed and restricted securities.

The Fund may invest in China A-Shares (shares of publicly traded companies based in mainland China) listed and traded on the Shanghai Stock Exchange through the Shanghai Hong Kong Stock Connect program, as well as China A Shares listed and traded on the Stock Connect.

Derivative instruments used by the Fund will be counted toward the Fund’s exposure in the types of securities listed above to the extent they have economic characteristics similar to such securities.

Investment Objective

The International Opportunity Portfolio seeks long-term capital appreciation.

Approach

Process

The Adviser emphasizes a bottom-up stock selection process, seeking attractive investments on an individual company basis. In selecting securities for investment, the Adviser seeks high quality established and emerging companies that the Adviser believes are undervalued at the time of purchase. The Adviser typically favors companies it believes have sustainable competitive advantages that can be monetized through growth. The investment process integrates analysis of sustainability with respect to disruptive change, financial strength, environmental and social externalities and governance (also referred to as ESG). The Adviser typically focuses a significant portion of the Fund’s investments in a limited number of issuers, which may be in the same industry, sector or geographic region. The Adviser generally considers selling a portfolio holding when it determines that the holding no longer satisfies its investment criteria.

This section discusses additional information relating to Fund investment strategies, other types of investments that the Funds may make and related risk factors. “Fund” as used herein and under “Additional Information About Fund Investment Strategies and Related Risks” refers to each Fund listed on the cover page of this Prospectus (unless otherwise noted). Fund investment practices and limitations are described in more detail in the Statement of Additional Information (“SAI”), which is incorporated by reference and legally is a part of this Prospectus. For details on how to obtain a copy of the SAI and other reports and information, see the back cover of this Prospectus.

There is no assurance that the Fund will achieve its investment objective. The Fund’s share price and yield will fluctuate with changes in the market value and/or yield of the Fund’s portfolio securities. When you sell Fund shares, they may be worth less than what you paid for them and, accordingly, you can lose money investing in this Fund.

Economies and financial markets worldwide have recently experienced periods of increased volatility, uncertainty, distress, government spending, inflation and disruption to consumer demand, economic output and supply chains. To the extent these conditions continue, the risks associated with an investment in the Fund, including those described below, could be heightened and the Fund’s investments (and thus a shareholder’s investment in the Fund) may be particularly susceptible to sudden and substantial losses, reduced yield or income or other adverse developments. The occurrence, duration and extent of these or other types of adverse economic and market conditions and uncertainty over the long term cannot be reasonably projected or estimated at this time.

The percentage limitations relating to the composition of the Fund’s portfolio apply at the time the Fund acquires an investment. Subsequent percentage changes that result from market fluctuations generally will not require the Fund to sell any portfolio security. However, the Fund may be required to reduce its borrowings, if any, in response to fluctuations in the value of such holdings. The Fund may change its principal investment strategies without shareholder approval; however, you would be notified of any changes.

Asia Market

Many of the currencies in Asia have recently experienced extreme volatility relative to the U.S. dollar. For example, Thailand, Indonesia, the Philippines and South Korea have had currency crises and have sought help from the International Monetary Fund. Holding securities in currencies that are devalued (or in companies whose revenues are substantially in currencies that are devalued) will likely decrease the value of a Fund.

The trading volume on some Asian stock exchanges is much lower than in the United States, and Asian securities of some companies are less liquid and more volatile than similar U.S. securities. In addition, brokerage commissions on regional stock exchanges are fixed and are generally higher than the negotiated commissions in the United States. Because certain Funds concentrate in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Asian securities fall out of favor, it may cause a Fund to underperform funds that do not concentrate in a single region of the world.

Investing in certain Funds may be appropriate for you if you are willing to accept the risks and uncertainties of investing in a portfolio of equity securities of issuers located in Asia (excluding Japan). In general, prices of equity securities are more volatile than those of fixed-income securities. The prices of equity securities will rise and fall in response to a number of different factors. In particular, 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 and political conditions.

The small size of securities markets and the low trading volume in many countries in Asia, among other factors, may lead to a lack of liquidity. The share prices of companies in the region tend to be volatile and there is a significant possibility of loss, including as a result of diplomatic, trade or military conflicts. Many of the countries in the region are developing, both politically and economically, and as a result companies in the region may be subject to risks like nationalization or other forms of government interference, and/or may be heavily reliant on only a few industries or commodities. Investments in the region may also be subject to currency risks, such as restrictions on the flow of money in and out of the country, extreme volatility relative to the U.S. dollar and devaluation, all of which could decrease the value of a Fund. Some countries in the region have previously experienced currency devaluations that resulted in higher interest rates, reductions in economic activity and drops in securities prices.

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 a 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 a 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 a Fund may be forced to sell such restricted securities and incur a loss as a result.

Risks of Investing through Stock Connect. A 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 a Fund’s investments and returns. For example, trading through Stock Connect is subject to daily quotas that limit the maximum daily net purchases on any particular day, which may restrict or preclude a Fund’s ability to invest in Stock Connect A-shares. In addition, investments made through Stock Connect are subject to trading, clearance and settlement procedures that are relatively untested in China, which could pose risks to a Fund. Furthermore, securities purchased via Stock Connect will be held via a book entry omnibus account in the name of Hong Kong Securities Clearing Company Limited (“HKSCC”), Hong Kong’s clearing entity, at the China Securities Depository and Clearing Corporation Limited (“CSDCC”). A Fund’s ownership interest in Stock Connect securities will not be reflected directly in book entry with CSDCC and will instead only be reflected on the books of its Hong Kong sub-custodian. A Fund may therefore depend on HKSCC’s ability or willingness as record-holder of Stock Connect securities to enforce a Fund’s shareholder rights. Chinese law did not historically recognize the concept of beneficial ownership; while Chinese regulations and the Hong Kong Stock Exchange have issued clarifications and guidance supporting the concept of beneficial ownership via Stock Connect, the interpretation of beneficial ownership in China by regulators and courts may continue to evolve. 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 a Fund’s investments or returns. In addition, the application and interpretation of the laws and regulations of China and Hong Kong, and the rules, policies or guidelines published or applied by relevant regulators and exchanges in respect of the Stock Connect program, are uncertain, and they may have a detrimental effect on a Fund’s investments and 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) it engages in its trading in China A Shares.

Variable Interest Entities. A Fund could seek to gain economic exposure to certain operating companies in China through legal structures known as variable interest entities (“VIEs”). 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. More specifically, in a VIE structure, a China-based operating company (“Operating Company”) typically establishes an offshore shell company (“Shell Company”) in another jurisdiction, such as the Cayman Islands, which generally does not conduct operations but enters into service and other contracts with the Operating Company and issues shares on a foreign exchange, like the New York Stock Exchange or Hong Kong Exchange. U.S. investors, such as a Fund, would hold stock in the Shell Company with contractual arrangements with a VIE based in China rather than hold stock in the Operating Company and the Shell Company does not typically own stock or other equity in the Operating Company. Thus, VIE structures and these contractual arrangements are not equivalent to equity ownership in the Operating Company, which presents additional risks. Certain Chinese companies have used VIEs to facilitate foreign investment because of Chinese governmental prohibitions or restrictions on non-Chinese ownership (e.g., by U.S. persons and entities) of companies in certain industries in China. Through a VIE arrangement, the Operating Companies indirectly raise capital from U.S. investors (such as a Fund) without distributing ownership of the Operating Companies to such U.S. investors.

Investments in VIEs are subject to unique risks in addition to those generally associated with investments in China. For example, breaches of the contractual arrangements, changes in Chinese law or regulation with respect to enforceability or permissibility of these arrangements or failure of these contracts to function as intended would likely adversely materially affect the Operating Company’s performance and an investment in the Shell Company. In addition, VIE structures are also subject to the risk of inconsistent and unpredictable application of Chinese law and regulations, that the Shell Company could be limited in its ability to control, or may lose control over, the Operating Company, and that the equity owners of the Operating Company might have interests conflicting with those of the Shell Company’s investors. There is also uncertainty related to the Chinese taxation of VIEs and the Chinese tax authorities could take positions that result in increased tax liabilities. Thus, investors, such as the Funds, face

risks and uncertainty about future actions or intervention by the government of China or other similar developments (such as changes in regulations, laws and judicial decisions or interpretations), which could occur at any time and without advance notice and which could suddenly and significantly affect VIE structures, the Operating Companies and the Shell Companies (such as impacting or limiting the enforceability of the Shell Company’s contractual arrangements with the Operating Company or restricting the listing of the shares of the offshore entity). If any of these or similar risks materialize, the value and liquidity of a Fund’s investments in the Shell Company would likely be significantly adversely affected, causing a Fund to incur significant losses with no recourse available.

Although the China Securities Regulatory Commission published its position that it does not object to the use of VIE structures for Operating Companies to raise capital from non-Chinese investors, there is no guarantee that the Chinese government or Chinese regulator or court will not determine that these arrangements are inconsistent with Chinese laws or regulations or otherwise interfere with the operation of or disallow VIE structures or that this published position will remain unchanged. Intervention by the Chinese government with respect to VIE structures could materially adversely affect the Operating Company’s performance, the enforceability of the Shell Company’s contractual arrangements with the Operating Company and the value of the Shell Company’s shares. Further, if the Chinese government or other regulatory or judicial authority determines that the agreements establishing the VIE structure do not comply with Chinese law and regulations, including those related to prohibitions on foreign ownership, the Operating Company could be subject to penalties, revocation of business and operating licenses or forfeiture of ownership interests. Much of the value of an investment in the Shell Company depends on the enforceability of the contractual arrangements entered into as part of the VIE structure, which are generally less effective than direct ownership, and a Shell Company’s ability to exert any control over the Operating Company could be jeopardized if certain legal formalities are not observed in connection with the agreements, if the agreements are breached, or if the agreements are otherwise determined not to be enforceable. In addition, the Offshore Company could incur significant costs to seek to enforce the terms of these arrangements because of, among other things, legal uncertainties and jurisdictional limits. If any of the foregoing or similar developments were to occur, the market value and liquidity of the associated investments would fall, causing substantial investment losses for investors with no recourse available.

India Risk

Investments in securities of Indian issuers 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. In addition, the economy of India may differ favorably or unfavorably from the U.S. economy in such respects as the rate of growth of gross domestic product, the rate of inflation, capital reinvestment, resource self-sufficiency and balance of payments position. The Indian government has exercised and continues to exercise significant influence over many aspects of the economy, and the number of public sector enterprises in India is substantial. Accordingly, 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 substantial 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.

Equity Securities

Equity securities may include common and preferred stocks, convertible securities and equity-linked securities, rights and warrants to purchase common stocks, depositary receipts, shares of investment companies (including those which may be managed by the Adviser or its affiliates), limited partnership interests and other specialty securities having equity features. Many factors affect the value of equity securities, including earnings, earnings forecasts, corporate events and factors impacting the issuer’s industry and the market generally. The Funds may invest in equity securities that are publicly traded on securities exchanges or over-the-counter (“OTC”) or in equity securities that are not publicly traded. Securities that are not publicly traded may be more difficult to value or sell and their value may fluctuate more dramatically than other securities. The prices of convertible securities are affected by changes similar to those of equity and fixed-income securities.

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.

Depositary Receipts

A depositary receipt is generally issued by a bank or financial institution and represents the common stock or other equity securities of a foreign company. Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities.

Convertible Securities

A convertible security is a bond, debenture, note, preferred stock, right, warrant or other security that may be converted into or exchanged for a prescribed amount of common stock or other security of the same or a different issuer or into cash within a particular period of time at a specified price or formula. A convertible security generally entitles the holder to receive interest paid or accrued on debt securities or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged.

Before conversion, convertible securities generally have characteristics similar to both debt and equity securities. The prices of convertible securities are affected by changes similar to those of equity and fixed-income securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities. Convertible securities ordinarily provide a stream of income with generally higher yields than those of common stock of the same or similar issuers. Convertible securities generally rank senior to common stock in a corporation’s capital structure but are usually subordinated to other comparable nonconvertible fixed-income securities in such capital structure. Convertible securities generally do not participate directly in any dividend increases or decreases of the underlying securities although the market prices of convertible securities may be affected by any dividend changes or other changes in the underlying securities.

Market and Geopolitical Risk

The value of your investment in the Fund is based on the values of the Fund’s investments, which change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. Price movements, sometimes called volatility, may be greater or less depending on the types of securities the Fund owns and the markets in which the securities trade. Volatility and disruption in financial markets and economies may be sudden and unexpected, expose the Fund to greater risk, including risks associated with reduced market liquidity and fair valuation, and adversely affect the Fund’s operations. For example, the Adviser potentially will be prevented from executing investment decisions at an advantageous time or price as a result of any domestic or global market disruptions, and reduced market liquidity may impact the Fund’s ability to sell securities to meet redemptions.

The increasing interconnectivity between global economies and markets increases the likelihood that events or conditions in one region or market may adversely impact other companies and issuers in a different country, region, sector, industry, market or with respect to one company may adversely impact other companies and issuers in a different country, region, sector, industry, or market. For example, adverse developments in the banking or financial services sector could impact companies operating in various sectors or industries and adversely impact the Fund’s investments. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters and extreme weather events, health emergencies (such as epidemics and pandemics), terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events, such as terrorist attacks around the world, natural disasters, health emergencies, social and political (including geopolitical) discord and tensions or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. Inflation rates may change frequently and significantly because of various factors, including unexpected shifts in the domestic or global economy and changes in monetary or economic policies (or expectations that these policies may change). Changes in expected inflation rates may adversely affect market and economic conditions, the Fund’s investments and an investment in the Fund. Other financial, economic and other global market and social developments or disruptions may result in similar adverse circumstances, and it is difficult to predict when similar 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). In general, the securities or other instruments that the Adviser believes represent an attractive investment opportunity or in which the Fund seeks to invest may be unavailable entirely or in the specific quantities sought by the Fund. As a result, the Fund may need to obtain the desired exposure through a less advantageous investment, forgo the investment at the time or seek to replicate the desired exposure through a derivative transaction or investment in another investment vehicle. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. There is a risk that you may lose money by investing in the Fund.

Social, political, economic and other conditions and events, such as war, natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, conflicts, social unrest, recessions, inflation, interest rate changes and supply chain disruptions could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and generally have a significant impact on the economies and financial markets and the Adviser’s investment advisory activities and services of other service providers, which in turn could adversely affect the Fund’s investments and other operations.

Governmental and quasi-governmental responses to certain economic or other conditions may lead to increasing government and other public debt, which heighten these risks. Unsustainable debt levels can lead to declines in the value of currency, and can prevent a government from implementing effective counter-cyclical fiscal policy during economic downturns, can generate or contribute to an economic downturn or cause other adverse economic or market developments, such as increases in inflation or volatility. Increasing government and other public debt may adversely affect issuers, obligors, guarantors or instruments across a variety of asset classes.

Global events may negatively impact broad segments of businesses and populations, cause a significant negative impact on the performance of the Fund’s investments, adversely affect and increase the volatility of the Fund’s share price, exacerbate pre-existing political, social and economic risks to the Fund. The Fund’s operations may be interrupted as a result, which may contribute to the negative impact on investment performance. In addition, governments, their regulatory agencies, or self-regulatory organizations may take actions that affect the instruments in which the Fund invests, or the issuers of such instruments, in ways that could have a significant negative impact on the Fund’s investment performance. In addition, government actions (such as changes to interest rates) could have unintended economic and market consequences that adversely affect the Fund’s investments.

ESG Investment Risk

To the extent that the Adviser considers ESG issues as a component in its investment decision-making process, the Fund’s performance may be impacted. Additionally, the Adviser’s consideration of ESG issues in its investment decision-making process may require subjective analysis and the ability of the Adviser to consider ESG issues may be difficult if data about a particular issuer (or obligor) is limited. The Adviser’s consideration of ESG issues may contribute to the Adviser’s decision to forgo opportunities to buy certain securities. ESG issues with respect to an issuer (or obligor) or the Adviser’s assessment of such may change over time.

Foreign Investing

To the extent that a Fund invests in foreign issuers, there is the risk that news and events unique to a country or region will affect those markets and their issuers. These same events will not necessarily have an effect on the U.S. economy or similar issuers located in the United States. In addition, some of the Funds’ securities, including underlying securities represented by depositary receipts, may be denominated in foreign currencies. As a result, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of a Fund’s investments. These changes may happen separately from, and in response to, events that do not otherwise affect the value of the security in the issuer’s home country. These risks may be intensified for a Fund’s investments in securities of issuers located in emerging market or developing countries.

Foreign Securities

Foreign issuers generally are subject to different accounting, auditing and financial reporting standards than U.S. issuers. There may be less information available to the public about foreign issuers. Securities of foreign issuers can be less liquid and experience greater price movements. In addition, the prices of such securities may be susceptible to influence by large traders, due to the limited size of many foreign securities markets. Moreover, investments in certain foreign markets that have historically been considered stable may become more volatile and subject to increased risk due to developments and changing conditions in such markets. Also, 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. In some foreign countries, there is also the risk of government expropriation, excessive taxation, political or social instability, the imposition of currency controls or diplomatic developments that could affect a Fund’s investment. There also can be difficulty obtaining and enforcing judgments against issuers in foreign countries. Foreign stock exchanges, broker-dealers and listed issuers may be subject to less government regulation and oversight. The cost of investing in foreign securities, including brokerage commissions and custodial expenses, can be higher than the cost of investing in domestic securities.

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, tariffs, trade barriers and other protectionist or retaliatory measures. International trade barriers or economic sanctions against foreign countries, organizations, companies, entities and/or individuals may adversely affect a Fund’s foreign holdings or exposures. Investments in foreign markets may also be adversely affected by less stringent investor protections and disclosure standards, and governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. Governmental actions can have a significant effect on the economic conditions in foreign countries, which also may adversely affect the value and liquidity of a Fund’s investments. Foreign investment in the securities markets of certain foreign countries is restricted or controlled to varying degrees. For example, 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. Moreover, if a deterioration occurs in a country’s balance of payments, the country could impose temporary restrictions on foreign capital remittances. A Fund could also be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation, as well as by the application to it of other restrictions on investment. Any of these actions could severely affect security prices, which could result in losses to a Fund and increased transaction costs, impair a Fund’s ability to purchase or sell foreign securities or transfer a Fund’s assets back into the United States, or otherwise adversely affect a Fund’s operations. Certain foreign investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by a Fund, particularly during periods of market turmoil. Certain foreign investments may become illiquid when, for instance, there are few, if any, interested buyers and sellers or when dealers are unwilling to make a market for certain securities. When a Fund holds illiquid investments, its portfolio may be harder to value.

Economic sanctions or other similar measures may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. A Fund’s investments in foreign securities are subject to trade laws and potential economic sanctions in the United States and other jurisdictions. These laws and related governmental actions, including counter-sanctions and other retaliatory measures, can, from time to time, prevent or prohibit a Fund from investing in certain foreign securities. In addition, economic sanctions could prohibit a Fund from transacting with particular countries, organizations, companies, entities and/or individuals by banning them from global payment systems that facilitate cross-border payments, restricting their ability to settle securities transactions, and freezing their assets. The imposition of sanctions and other similar measures could, among other things, cause a decline in the value of securities issued by the sanctioned country or companies located in, or economically linked to, the

sanctioned country, downgrades in the credit ratings of the sanctioned country or companies located in, or economically linked to, the sanctioned country, devaluation of the sanctioned country’s currency, and increased market volatility and disruption in the sanctioned country and throughout the world. Economic sanctions or other similar measures could, among other things, effectively restrict or eliminate a Fund’s ability to purchase or sell securities, negatively impact the value or liquidity of a Fund’s investments, significantly delay or prevent the settlement of a Fund’s securities transactions, force a Fund to sell or otherwise dispose of investments at inopportune times or prices, increase a Fund’s transaction costs, make a Fund’s investments more difficult to value or impair a Fund’s ability to meet its investment objective or invest in accordance with its investment strategies. These conditions may be in place for a substantial period of time and enacted with limited advance notice to a Fund. Even if the Fund does not have significant investments in securities affected by sanctions, sanctions or the threat of sanctions may cause volatility in regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, including through global supply chain disruptions, increased inflationary pressures, and reduced economic activity, which could have a negative effect on the Fund’s performance. In addition, trade disputes may affect investor and consumer confidence and adversely affect financial markets and the broader economy, perhaps suddenly and to a significant degree. Events such as these and their impact on the Fund are difficult to predict.

In addition, the Holding Foreign Companies Accountable Act (the “HFCAA”) could cause securities of a foreign (non-U.S.) company, including American Depositary Receipts, to be delisted from U.S. stock exchanges if the company does not allow the U.S. government to oversee the auditing of its financial information. Although the requirements of the HFCAA apply to securities of all foreign (non-U.S.) issuers, the SEC has thus far limited its enforcement efforts to securities of Chinese companies. If securities are delisted, the Fund’s ability to transact in such securities will be impaired, and the liquidity and market price of the securities may decline. The Fund may also need to seek other markets in which to transact in such securities, which could increase the Fund’s costs.

Emerging Market Securities

Certain Funds may invest in emerging market or developing countries, which are countries that major international financial institutions 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 may be more likely to experience political turmoil or rapid changes in economic conditions than more developed countries, and the financial condition of issuers in emerging market or developing countries may be more precarious than in other 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, a 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 markets countries. In addition, due to jurisdictional limitations, U.S. authorities (e.g., SEC and the U.S. Department of Justice) may be limited in their ability to enforce regulatory or legal obligations in emerging market countries. In addition, emerging market securities generally are less liquid and subject to wider price and currency fluctuations than securities issued in more developed countries. These characteristics result in greater risk of price volatility in emerging market or developing countries, which may be heightened by currency fluctuations relative to the U.S. dollar.

Foreign Currency

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 or other applicable foreign currency. Since the Funds may invest in 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 Funds’ 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 seek 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.

Foreign Currency Forward Exchange Contracts

In connection with their investments in foreign securities, the Funds also may enter into contracts with banks, brokers or dealers to purchase or sell securities or foreign currencies at a future date. A foreign currency forward exchange contract is a negotiated agreement between the contracting parties to exchange a specified amount of currency at a specified future time at a specified rate. The rate can be higher or lower than the spot rate between the currencies that are the subject of the contract. Foreign currency forward exchange contracts may be used to seek to protect against uncertainty in the level of future foreign currency exchange rates or to gain or modify exposure to a particular currency. In addition, the Fund may use cross currency hedging or proxy hedging with respect to currencies in which the Fund has or expects to have portfolio or currency exposure. Cross currency and proxy hedges

involve the sale of one currency against the positive exposure to a different currency and may be used for hedging purposes or to establish an active exposure to the exchange rate between any two currencies.

Investments in foreign currency forward exchange contracts may substantially change the Funds’ exposure to currency exchange rates and could result in losses to the Funds if currencies do not perform as the Adviser expects. The Adviser’s success in these transactions will depend principally on its ability to predict accurately the future exchange rates between foreign currencies and the U.S. dollar. Foreign currency forward exchange contracts may be used for non-hedging purposes in seeking to meet the Funds’ investment objectives, such as when the Adviser anticipates that particular non-U.S. currencies will appreciate or depreciate in value, even though securities denominated in those currencies are not then held in the Funds’ investment portfolios. Investing in foreign currency forward exchange contracts for purposes of gaining from projected changes in exchange rates, as opposed to hedging currency risks applicable to the Funds’ holdings, further increases the Funds’ exposure to foreign securities losses. There is no assurance that the Adviser’s use of currency derivatives will benefit the Funds or that they will be, or can be, used at appropriate times.

REITs and Foreign Real Estate Companies

Investing in real estate investment trusts (“REITs”) and foreign real estate companies exposes investors to the risks of owning real estate directly and investing in companies in the real estate industry, including the risks associated with residential and commercial real estate, as well as to risks that relate specifically to the way in which REITs and foreign real estate companies are organized and operated. REITs and foreign real estate companies generally invest directly in real estate, in mortgages or in some combination of the two. Real estate income and values may also be greatly affected by demographic trends, such as population shifts or changing tastes, preferences (such as remote work arrangements) and values.

Operating REITs and foreign real estate companies requires specialized management skills and a Fund indirectly bears management expenses along with the direct expenses of a Fund. The value of REIT and foreign real estate company securities will also rise and fall in response to the management skill and creditworthiness of the issuer. In particular, the value of these securities may decline when interest rates rise and will also be affected by the real estate market and by the management or development of the underlying properties, which may be subject to mortgage loans and the underlying mortgage loans may be subject to the risks of default.

REITs may be more volatile and/or more illiquid than other types of securities, and publicly traded REIT and real estate company shares are also subject to risks associated with equity securities. In addition, individual REITs and foreign real estate companies may own a limited number of properties and may concentrate in a particular region or property type. REITs may also be subject to heavy cash flow dependency, default by borrowers and self-liquidation.

REITs also must satisfy specific requirements of the Internal Revenue Code of 1986, as amended (“the Code”) in order to qualify for tax-free pass-through income. The failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing the return to a Fund on its investment in such company. Foreign real estate companies may be subject to laws, rules and regulations governing those entities and their failure to comply with those laws, rules and regulations could negatively impact the performance of those entities. In addition, REITs and foreign real estate companies, like mutual funds, have expenses, including management and administration fees, that are paid by their shareholders. As a result, shareholders will directly bear the expenses of their investment in the Fund and indirectly bear the expenses of the Fund’s investments when a Fund invests in REITs and foreign real estate companies.

Derivatives

The Fund may, but is not required to, use derivatives and other similar instruments for a variety of purposes, including hedging, risk management, portfolio management or to seek to earn income. Derivative instruments used by the Fund will be counted towards the Fund’s exposure in the types of securities listed herein to the extent they have economic characteristics similar to such securities. A derivative is a financial instrument whose value is based, in part, on the value of an underlying asset, interest rate, index or financial instrument. Prevailing interest rates and volatility levels, among other things, also affect the value of derivative instruments. Derivatives and other similar instruments that create synthetic exposure often are subject to risks similar to those of the underlying asset or instrument and may be subject to 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. The use of derivatives involves risks that are different from, and possibly greater than, the risks associated with other portfolio investments. Derivatives may involve the use of highly specialized instruments that require investment techniques and risk analyses different from those associated with other portfolio investments.

Certain derivatives transactions may give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss. Leverage associated with derivative transactions may cause the Fund to liquidate portfolio positions when it may not be advantageous

to do so, or may cause the Fund to be more volatile than if the Fund had not been leveraged. Although the Adviser seeks to use derivatives to further the Fund’s investment objective, there is no assurance that the use of derivatives will achieve this result.

The derivative instruments and techniques that the Fund may use include:

Futures. A futures contract is a standardized, exchange-traded agreement to buy or sell a specific quantity of an underlying asset, reference rate or index at a specific price at a specific future time. While the value of a futures contract tends to increase or decrease in tandem with the value of the underlying instrument, differences between the futures market and the market for the underlying asset may result in an imperfect correlation. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. A decision as to whether, when and how to use futures contracts involves the exercise of skill and judgment and even a well-conceived futures transaction may be unsuccessful because of market behavior or unexpected events. In addition to the derivatives risks discussed above, the prices of futures contracts can be highly volatile, using futures contracts can lower total return, and the potential loss from futures contracts can exceed the Fund’s initial investment in such contracts. No assurance can be given that a liquid market will exist for any particular futures contract at any particular time. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with which the Fund has open positions in the futures contract.

Options. If the Fund buys an option, it buys a legal contract giving it the right to buy or sell a specific amount of the underlying instrument, foreign currency or contract, such as a swap agreement or futures contract, on the underlying instrument or foreign currency at an agreed-upon price typically in exchange for a premium paid by the Fund. If the Fund sells an option, it sells to another person the right to buy from or sell to the Fund a specific amount of the underlying instrument, swap, foreign currency, or futures contract on the underlying instrument or foreign currency at an agreed-upon price during a period of time or on a specified date typically in exchange for a premium received by the Fund. When options are purchased OTC, the Fund bears the risk that the counterparty that wrote the option will be unable or unwilling to perform its obligations under the option contract. Options may also be illiquid and the Fund may have difficulty closing out its position. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well-conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile and the use of options can lower total returns.

Investments in foreign currency options may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the Adviser expects. There is a 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. The value of a foreign currency option is dependent upon the value of the underlying foreign currency relative to the U.S. dollar or other applicable foreign currency. The price of the option may vary with changes in the value of either or both currencies and has no relationship to the investment merits of a foreign security. Options on foreign currencies are affected by all of those factors that influence foreign exchange rates and foreign investment generally. Unanticipated changes in currency prices may result in losses to the Fund and poorer overall performance for the Fund than if it had not entered into such contracts. Options on foreign currencies are traded primarily in the OTC market, but may also be traded on U.S. and foreign exchanges.

Foreign currency options contracts may be used for hedging purposes or non-hedging purposes in pursuing the Fund’s investment objective, such as when the Adviser anticipates that particular non-U.S. currencies will appreciate or depreciate in value, even though securities denominated in those currencies are not then held in the Fund’s investment portfolio. Investing in foreign currencies for purposes of gaining from projected changes in exchange rates, as opposed to only hedging currency risks applicable to the Fund’s holdings, further increases the Fund’s exposure to foreign securities losses. There is no assurance that the Adviser’s use of currency derivatives will benefit the Fund or that they will be, or can be, used at appropriate times.

Swaps. The Fund may enter into OTC swap contracts or cleared swap transactions. An OTC swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indices, reference rates, currencies or other instruments. Typically swap agreements provide that when the period payment dates for both parties are the same, the payments are made on a net basis (i.e., the two payment streams are netted out, with only the net amount paid by one party to the other). The Fund’s obligations or rights under a swap contract entered into on a net basis will generally be equal only to the net amount to be paid or received under the agreement, based on the relative values of the positions held by each party. Cleared swap transactions may help reduce counterparty credit risk. In a cleared swap, the Fund’s ultimate counterparty is a clearinghouse rather than a swap dealer, bank or other financial institution. OTC swap agreements are not entered into or traded on exchanges and often there is no central clearing or guaranty function for swaps. These OTC swaps are often subject to credit risk or the risk of default or non-performance by the counterparty. Certain swaps have begun trading on exchanges called swap execution facilities. Exchange trading is expected to increase liquidity of swaps trading. Both OTC and cleared swaps could result in losses if interest rates, foreign currency exchange rates or other factors are not correctly anticipated by the Fund or if the reference index, security or investments do not perform as expected. The Dodd-Frank Wall Street Reform and Consumer Protection Act and related regulatory developments require the clearing and exchange trading of certain standardized swap transactions. Mandatory exchange-trading and clearing is occurring on a phased-in basis. The Fund may pay fees or incur costs each time it enters into, amends or terminates a swap agreement.

The Fund’s use of swaps may include those based on the credit of an underlying security, commonly referred to as “credit default swaps.” Where the Fund is the buyer of a credit default swap contract, it would typically be entitled to receive the par (or other agreed-upon) value of a referenced debt obligation from the counterparty to the contract only in the event of a default or similar event by a third-party on the debt obligation. If no default occurs, the Fund would have paid to the counterparty a periodic stream of payments over the term of the contract and received no benefit from the contract. When the Fund is the seller of a credit default swap contract, it typically receives the stream of payments but is obligated to pay an amount equal to the par (or other agreed-upon) value of a referenced debt obligation upon the default or similar event of the issuer of the referenced debt obligation.

Structured Investments. Certain Funds also may invest a portion of their assets in structured investments. A structured investment is a derivative security designed to offer a return linked to a particular underlying security, currency, commodity or market. Structured investments may come in various forms including notes (such as exchange-traded notes), warrants and options to purchase securities. The Funds will typically use structured investments to gain exposure to a permitted underlying security, currency, commodity or market when direct access to a market is limited or inefficient from a tax or cost standpoint. There can be no assurance that structured investments will trade at the same price or have the same value as the underlying security, currency, commodity or market. Investments in structured investments involve risks including issuer risk, counterparty risk and market risk. Holders of structured investments bear risks of the underlying investment and are subject to issuer or counterparty risk because a Fund is relying on the creditworthiness of such issuer or counterparty and has no rights with respect to the underlying investment. Certain structured investments may be thinly traded or have a limited trading market and may have the effect of increasing a Fund’s illiquidity to the extent that a Fund, at a particular point in time, may be unable to find qualified buyers for these securities.

CFDs. A contract for difference (“CFD”) is a privately-negotiated contract between two parties, buyer and seller, stipulating that the seller will pay to or receive from the buyer the difference between the nominal value of the underlying instrument at the opening of the contract and that instrument’s value at the end of the contract. The underlying instrument may be a single security, stock basket or index. A CFD can be set up to take either a short or long position on the underlying instrument. The buyer and seller are typically both required to post margin, which is adjusted daily. The buyer will also pay to the seller a financing rate on the notional amount of the capital employed by the seller less the margin deposit. In addition to the general risks of derivatives, CFDs may be subject to liquidity risk and counterparty risk.

Exchange-Traded Funds

Each Fund may invest in exchange-traded funds (“ETFs”) (including those which may be managed by the Adviser or its affiliates). ETFs seek to track the performance of various portions or segments of the equity and fixed-income markets. Shares of ETFs have many of the same risks as direct investments in common stocks or bonds. In addition, the market value of ETF shares may differ from their NAV because the supply and demand in the market for ETF shares at any point in time is not always identical to the supply and demand in the market for the underlying securities. Also, ETFs that track particular indices typically will be unable to match the performance of the index exactly due to, among other things, the ETF’s operating expenses and transaction costs. ETFs typically incur fees that are separate from those fees incurred directly by the Fund. Therefore, as a shareholder in an ETF, a Fund would bear its ratable share of that entity’s expenses. At the same time, the Fund would continue to pay its own investment management fees and other expenses. As a result, shareholders will directly bear the expenses of their investment in a Fund and indirectly bear the expenses of a Fund’s investments in ETFs with respect to investments in ETFs.

Focused Investing

Although the Fund is a diversified investment company under the Investment Company Act of 1940 (the “1940 Act”), the Fund typically invests a significant portion of its portfolio in a limited number of issuers, which may be in the same industry, sector or geographic region. As a result, the Fund will be more susceptible to risks associated with, and negative events, conditions or developments affecting or economic results of, those issuers, industries, sectors or geographic regions, and a decline in the value of a particular instrument may cause the Fund’s overall value to be more volatile and decline to a greater degree than if the Fund were invested more widely. Such volatility and decline may be sudden and significant. In addition, if such issuers are within the same market segment or of a similar type (e.g., growth stocks), the Fund will be more sensitive to adverse developments or conditions and risks affecting such market segment or type of issuer, including that the market segment or type of issuer may fall out of favor, than if the Fund were invested more widely.

The Fund does not lose its status as a diversified investment company because of any subsequent discrepancy between the value of its various investments and the diversification requirements of the 1940 Act, so long as any such discrepancy existing immediately after the Fund’s acquisition of any security or other property is neither wholly nor partly the result of such acquisition.

Large Shareholder Transactions Risk

A Fund may experience adverse effects when certain shareholders, or shareholders collectively, purchase or redeem large amounts of shares of a Fund. Such larger than normal redemptions may cause a Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact a Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect a Fund’s performance to the extent that a Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of

investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, leading to an increase in a Fund’s expense ratio. Although large shareholder transactions may be more frequent under certain circumstances, a Fund is generally subject to the risk that shareholders can purchase or redeem a significant percentage of Fund shares at any time.

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. Illiquidity can be caused by, among other things, a drop in overall market trading volume, an inability to find a willing buyer, or legal restrictions on the securities’ resale. 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 and may be unable to sell the security at all.

Special Purpose Acquisition Companies

A special purpose acquisition company (“SPAC”) is a publicly traded company that raises investment capital for the purpose of acquiring or merging with an existing company. Typically, the acquisition target is an existing privately held company that wants to trade publicly, which it accomplishes through a combination with a SPAC rather than by conducting a traditional initial public offering (“IPO”). SPACs and similar entities are blank check companies and do not have any operating history or ongoing business other than seeking acquisitions. The long term value of a SPAC’s securities is particularly dependent on the ability of the SPAC’s management to identify a merger target and complete an acquisition.

An investment in a SPAC is subject to the risks that any proposed acquisition or merger may not obtain the requisite approval of SPAC shareholders, may require governmental or other approvals that it fails to obtain or that an acquisition or merger, once effected, may prove unsuccessful and lose value. In addition, among other conflicts of interest, the economic interests of the management, directors, officers and related parties of a SPAC can differ from the economic interests of public shareholders, which may lead to conflicts as they evaluate, negotiate and recommend business combination transactions to shareholders. This risk may become more acute as the deadline for the completion of a business combination nears or in the event that attractive acquisition or merger targets become scarce.

An investment in a SPAC is also subject to the risk that a significant portion of the funds raised by the SPAC may be expended during the search for a target acquisition or merger. The value of investments in SPACs may be highly volatile and may depreciate over time. In addition, investments in SPACs may be subject to the same risks as investing in any initial public offering, including the risks associated with companies that have little operating history as public companies, including unseasoned trading, small number of shares available for trading and limited information about the issuer. In addition, the market for IPO issuers may be volatile, and share prices of newly-public companies have fluctuated significantly over short periods of time. Although some IPOs may produce high returns, such returns are not typical and may not be sustainable. Certain investments in SPACs are privately placed securities and are also subject to the risks of such securities.

Active Management Risk

In pursuing the Fund’s investment objective, the Adviser has considerable leeway in deciding which investments it buys, holds or sells on a day-to-day basis, and which trading strategies it uses. 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.

The success or failure of such decisions will affect the Fund’s performance. In addition, it is expected that confidential or material non-public information regarding an investment or potential investment opportunity may become available to the Adviser. If such information becomes available, the Adviser may be precluded (including by applicable law or internal policies or procedures) from pursuing an investment or disposition opportunity with respect to such investment or investment opportunity and the Adviser may be restricted in its ability to cause the Fund to buy or sell securities of an issuer for substantial periods of time when the Fund otherwise could realize profit or avoid loss. This may adversely affect the Fund’s flexibility with respect to buying or selling securities and may impair the Fund’s liquidity.

Temporary Defensive Investments

Under adverse or unstable market conditions or abnormal circumstances or when the Adviser believes that changes in market, economic, political or other conditions warrant, the Fund may, in the discretion of the Adviser, take temporary positions that are inconsistent with the Fund’s principal investment strategy in attempting to respond to such conditions or circumstances. For example, the Fund may invest without limit in cash, cash equivalents or other fixed-income securities for temporary defensive purposes. If the Adviser incorrectly predicts the effects of these changes, or during periods of temporary defensive or other temporary positions, such defensive investments may adversely affect a Fund’s performance and the Fund may not achieve its investment objective.

Consumer Discretionary

To the extent that the Fund invests a substantial portion of its assets in the consumer sector, the Fund will be particularly susceptible to the risks associated with companies operating in such sector(s). Companies in the consumer discretionary sector are subject to risks, including fluctuations in domestic and international economic conditions and forecasts, inflation, shipment and supply chain disruptions and interest rate changes, currency exchange rates, increased competition and consumer confidence as well as increases in production-related costs. Performance of such companies also may be adversely affected by factors such as reduced disposable household income, reduced consumer spending, and changing demographics and consumer tastes. Companies in this sector are subject to competitive forces (including competition brought by foreign brands), which may also have an adverse impact on their profitability and the value of their securities. This sector may be strongly affected by fads, marketing campaigns, changes in demographics and consumer preferences, and other economic or social factors affecting consumer demand. Governmental regulation, including price controls and regulations on packaging, labeling, competition, and certification, may affect the profitability of companies in such sector(s). Companies operating in this sector may also be adversely affected by government and private litigation.

Information Technology Sector Risk

To the extent a 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, competition for the services of qualified personnel and government regulation. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction and unpredictable changes in growth rates. Companies in the information technology sector also can be heavily dependent on patent protection and the expiration of patents may adversely affect the profitability of these companies. As a result, the value of shares may fluctuate more than that of a fund that does not invest significantly in companies in the technology sector.

Regulatory and Legal Risk

U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund (such as regulations related to investments in derivatives and other transactions). These regulations and laws impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

The SEC has recently proposed amendments to Rule 22e-4 of the 1940 Act that, if adopted, would result in changes to the Fund’s liquidity classification framework and could potentially increase the percentage of the Fund’s investments classified as illiquid. In addition, the Fund’s operations and investment strategies may be adversely impacted if the proposed amendments are adopted.

Adviser

Morgan Stanley Investment Management Inc., with principal offices at 1585 Broadway, New York, NY 10036, conducts a worldwide portfolio management business and provides a broad range of portfolio management services to customers in the United States and abroad. Morgan Stanley (NYSE: “MS”) is the parent of the Adviser, which is the parent of the Distributor. Morgan Stanley is a preeminent global financial services firm engaged in securities trading and brokerage activities, as well as providing investment banking, research and analysis, financing and financial advisory services. As of March 31, 2024, the Adviser, together with its affiliated asset management companies, had approximately $1.5 trillion in assets under management or supervision.

A discussion regarding the Board of Directors’ approval of the Investment Advisory Agreement is available in each Fund’s Semi-Annual Report to Shareholders for the period ended June 30, 2023.

Advisory Fees

For the fiscal year ended December 31, 2023, the Adviser received from each Fund the advisory fee (net of fee waivers, if applicable) set forth in the table below.


Fund (as a percentage of average daily net assets)
Global Opportunity	0.74%
International Opportunity	0.79%

The Adviser has agreed to reduce its advisory fee and/or reimburse the Funds, if necessary, if such fees would cause the total annual operating expenses of Class IR of each Fund to exceed the percentage of average daily net assets set forth in the table below. In determining the actual amount of fee waiver and/or expense reimbursement for a Fund, if any, the Adviser excludes from total annual operating expenses, acquired fund fees and expenses (as applicable), certain investment related expenses, taxes, interest and other extraordinary expenses (including litigation). The fee waivers and/or expense reimbursements for a Fund will continue for at least one year from the date of this Prospectus or until such time as the Company’s Board of Directors acts to discontinue all or a portion of such waivers and/or reimbursements when it deems such action is appropriate. The Adviser may make additional voluntary fee waivers and/or expense reimbursements. The Adviser may discontinue these voluntary fee waivers and/or expense reimbursements at any time in the future.

A Fund’s annual operating expenses may vary throughout the period and from year to year. A Fund’s actual expenses may be different than the expenses listed in the Fund’s fee and expense table based upon the extent and amount of a fee waiver and/or expense reimbursement.


Fund	Expense Cap Class IR
Global Opportunity	0.95%
International Opportunity	0.94%

Share Class Arrangements

This Prospectus offers Class IR shares of each Fund. The Company also offers investors Class I, Class A, Class L, Class C and Class R6 shares of each Fund through a separate prospectus. The Class L shares of the Funds are currently closed to all investors except in the limited circumstances set forth in such prospectus. Class IR shares are not subject to a sales charge and are not subject to a distribution and/or shareholder service (12b-1) fee. In addition, no sub-accounting or other similar fees, or any finder’s fee payments are charged or paid on Class IR shares.

Minimum Investment Amounts

Class IR shares are offered only to eligible investors meeting certain minimum investment requirements. To purchase Class IR 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 Code and in each case subject to the discretion of the Adviser. Initial omnibus trades of $5 million or more shall be accepted from certain platforms, including (i) banks and trust companies; (ii) insurance companies; and (iii) registered investment advisory firms. The $5 million minimum initial investment amount may be waived for Fund shares purchased by or through: (1) certain registered open-end investment companies whose shares are distributed by the Distributor; or (2) investments made in connection with certain mergers and/or reorganizations as approved by the Adviser.

If the value of your account falls below the applicable minimum initial investment amount for a class of shares of a Fund as a result of share redemptions or you no longer meet one of the waiver criteria set forth above, your account may be subject to involuntary conversion or involuntary redemption, as applicable. You will be notified prior to any such conversions or redemptions.

The Adviser, in its sole discretion, may waive a minimum initial investment amount in certain cases.

Distribution of Fund Shares

Morgan Stanley Distribution, Inc. is the exclusive distributor of the shares of each Fund. The Distributor receives no compensation from the Funds for distributing Class IR shares of the Funds.

The Adviser and/or Distributor may pay compensation to Financial Intermediaries in connection with the sale, distribution, marketing and retention of a Fund’s Class IR shares and/or Class IR shareholder servicing. Such compensation may be significant in amount and the prospect of receiving any such additional compensation may provide affiliated or unaffiliated Financial Intermediaries with an incentive to favor sales of shares of the Funds over other investment options. Any such payments will not change the NAV or the price of a Fund. For more information, please see the Funds’ SAI.

About Net Asset Value

The NAV of a class of shares of a Fund is determined by dividing the total of the value of the Fund’s investments and other assets attributable to the class, less any liabilities attributable to the class, by the total number of outstanding shares of that class of the Fund. In making this calculation, each Fund generally values its portfolio securities and other assets at market price. When no market quotations are readily available for a security or other asset, including circumstances under which the Adviser determines that a market quotation is not accurate, fair value for the security or other asset will be determined in good faith using methods approved by the Company’s Board of Directors.

In addition, with respect to securities that primarily are listed on foreign exchanges, when an event occurs after the close of such exchanges that is likely to have changed the value of the securities (e.g., a percentage change in value of one or more U.S. securities indices in excess of specified thresholds), such securities will be valued at their fair value, as determined in good faith using methods approved by the Company’s Board of Directors. Securities also may be fair valued in the event of a significant development affecting a country or region or an issuer-specific development that is likely to have changed the value of the security. In these cases, a Fund’s NAV will reflect certain portfolio securities’ fair value rather than their market price. To the extent a Fund invests in open-end management companies (other than ETFs) that are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), the Fund’s NAV is calculated based in relevant part upon the NAV of such funds. The prospectuses for such funds explain the circumstances under which they will use fair value pricing and its effects.

Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security or other asset is materially different than the value that could be realized upon the sale of that security or other asset. With respect to securities that are primarily listed on foreign exchanges, the values of a Fund’s portfolio securities may change on days when you will not be able to purchase or sell your shares. The NAV of a Fund (excluding any applicable sales charges) is based on the value of the Fund’s portfolio securities or other assets. Although the assets of each class are invested in the same portfolio of securities or other assets, the NAV of each class will differ because the classes have different class specific expenses.

The Funds rely on various sources to calculate their NAVs. The ability of a Fund’s provider of administrative services to calculate the NAV per share of the Fund is subject to operational risks associated with processing or human errors, systems or technology failures,

cyber attacks and errors caused by third party service providers, data sources, or trading counterparties. Such failures may result in delays in the calculation of the Fund’s NAV and/or the inability to calculate NAV over extended time periods. A Fund may be unable to recover any losses associated with such failures. In addition, if the third party service providers and/or data sources upon which a Fund directly or indirectly relies to calculate its NAV or price individual securities are unavailable or otherwise unable to calculate the NAV correctly, it may be necessary for alternative procedures to be utilized to price the securities at the time of determining the Fund’s NAV.

A Fund’s NAV per share is subject to various investment and other risks. Please refer to the “Additional Information About Fund Investment Strategies and Related Risks” and “Fund Investments and Strategies” sections of the Prospectus and SAI, respectively, for more information regarding risks associated with an investment in a Fund.

Pricing of Fund Shares

You may buy or sell (redeem) shares of the Funds at the NAV next determined for the class after receipt of your order in good order, plus any applicable sales charge. The Company determines the NAV for the Funds as of the close of the NYSE (normally 4:00 p.m. Eastern time) on each day that the NYSE is open for business (the “Pricing Time”). Shares generally will not be priced on days that the NYSE is closed. If the NYSE is closed due to inclement weather, technology problems or any other reason on a day it would normally be open for business, or the NYSE has an unscheduled early closing on a day it has opened for business, a Fund reserves the right to treat such day as a business day and accept purchase and redemption orders until, and calculate its NAV as of, the normally scheduled close of regular trading on the NYSE for that day, so long as the Adviser believes there generally remains an adequate market to obtain reliable and accurate market quotations. A Fund may elect to remain open and price its shares on days when the NYSE is closed but the primary securities markets on which the Fund’s securities trade remain open. Trading of securities, which are traded on exchanges other than the NYSE, may take place on days when a Fund does not price its shares. Therefore, to the extent, if any, that a Fund invests in securities traded on other exchanges, the value of the Fund’s portfolio securities may change on days when you will not be able to purchase or sell your shares.

Portfolio Holdings

A description of the Company’s policies and procedures with respect to the disclosure of each Fund’s portfolio securities is available in the Company’s SAI.

The Adviser may in its sole discretion permit a conversion of one share class to another share class of the same Fund in certain circumstances, provided that the Fund’s eligibility requirements are met, and subject to the shareholder’s consent. Such conversions will be on the basis of the relative NAVs and without the imposition of any redemption fee or other charge.

A conversion of shares of one class directly for shares of another class of the same Fund normally should not be taxable for federal income tax purposes.

Please ask your financial advisor if you are eligible for converting a class of shares pursuant to this conversion feature. You should talk to your tax advisor before making a conversion.

General

Shares of a Fund may, in the Fund’s discretion, be purchased with investment securities (in lieu of or, in conjunction with, cash) acceptable to the Fund. The securities would be accepted by the Fund at their market value in return for Fund shares of equal value, taking into account any applicable sales charge.

To help the U.S. Government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. What this means to you: when you open an account, we will ask your name, address, date of birth and other information that will allow us to identify you. If we are unable to verify your identity, we reserve the right to restrict additional transactions and/or liquidate your account at the next calculated NAV after your account is closed (less any applicable sales/account charges and/or tax penalties) or take any other action required by law. In accordance with federal law requirements, the Company has implemented an anti-money laundering compliance program, which includes the designation of an anti-money laundering compliance officer.

When you buy Fund shares, the shares will be purchased at the next share price calculated after we receive your purchase order in good order. Purchase orders not received in good order prior to Pricing Time will be executed at the NAV next determined after the purchase order is received in good order. Certain institutional investors and financial institutions have entered into arrangements with the Funds, the Adviser and/or the Distributor pursuant to which they may place orders prior to the Pricing Time, but make payment in Federal Funds for those shares up to three days after the purchase order is placed, depending on the arrangement. We reserve the right to reject any order for the purchase of Fund shares for any reason.

The Company may suspend the offering of shares, or any class of shares, of the Funds or reject any purchase orders when we think it is in the best interest of the Funds.

Certain patterns of past exchanges and/or purchase or sale transactions involving a Fund may result in the Fund rejecting, limiting or prohibiting, at its sole discretion, and without prior notice, additional purchases and/or exchanges and may result in a shareholder’s account being closed. Determinations in this regard may be made based on the frequency or dollar amount of previous exchanges or purchase or sale transactions. See “Frequent Purchases and Redemptions of Shares.”

How To Redeem Fund Shares

You may process a redemption request by contacting your Financial Intermediary. Otherwise, you may redeem shares of a Fund by mail or, if authorized, by telephone, at no charge other than as described below. The value of shares redeemed may be more or less than the purchase price, depending on the NAV at the time of redemption. Shares of a Fund will be redeemed at the NAV next determined after we receive your redemption request in good order and will be reduced by the amount of any applicable CDSC.

Redemptions by Letter
Requests should be addressed to Morgan Stanley Institutional Fund, Inc., c/o SS&C Global Investor and Distribution Solutions, Inc. P.O. Box 219804, Kansas City, MO 64121-9804.

To be in good order, redemption requests must include the following documentation:

(a) A letter of instruction, if required, or a stock assignment specifying the account name, the account number, the name of the Fund and the number of shares or dollar amount to be redeemed, signed by all registered owners of the shares in the exact names in which the shares are registered, and whether you wish to receive the redemption proceeds by check or by wire to the bank account we have on file for you;

(b) Any required signature guarantees if you are requesting payment to anyone other than the registered owner(s) or that payment be sent to any address other than the address of the registered owner(s) or pre-designated bank account; and

(c) Other supporting legal documents, if required, in the case of estates, trusts, guardianships, custodianship, corporations, pension and profit sharing plans and other organizations.

Redemptions by Telephone
You automatically have telephone redemption and exchange privileges unless you indicate otherwise by checking the applicable box on the New Account Application or calling Morgan Stanley Shareholder Services to opt out of such privileges. You may request a redemption of shares of a Fund by calling Morgan Stanley Shareholder Services at 1-800-869-6397 and requesting that the redemption proceeds be mailed or wired to you. You cannot redeem shares of a Fund by telephone if you hold share certificates for those shares. For your protection when calling the Fund, we will employ reasonable procedures to confirm that instructions communicated over the telephone are genuine. These procedures may include requiring various forms of personal identification (such as name, mailing address, social security number or other tax identification number), tape-recording telephone communications and providing written confirmation of instructions communicated by telephone. If reasonable procedures are employed, neither Morgan Stanley (or its affiliates) nor the Fund will be liable for following telephone instructions which it reasonably believes to be genuine. Telephone redemptions and exchanges may not be available if you cannot reach Morgan Stanley Shareholder Services by telephone, whether because all telephone lines are busy or for any other reason; in such case, a shareholder would have to use the Fund’s other redemption and exchange procedures described in this section. Telephone instructions will be accepted if received by Morgan Stanley Shareholder Services between 9:00 a.m. and 4:00 p.m. Eastern time on any day the NYSE is open for business. During periods of drastic economic or market changes, it is possible that the telephone privileges may be difficult to implement, although this has not been the case with the Fund in the past. To opt out of telephone privileges, please contact Morgan Stanley Shareholder Services at 1-800-869-6397.

Redemption Proceeds
Each Fund typically expects to pay redemption proceeds to you within two business days following receipt of your redemption request for those payments made to your brokerage account held with a Financial Intermediary. For redemption proceeds that are paid directly to you by a Fund, the Fund typically expects to pay redemption proceeds by check or by wire to you within one business day, following receipt of your redemption request; however, in all cases, it may take up to seven calendar days to pay redemption proceeds.

Each Fund typically expects to meet redemption requests by using a combination of sales of securities held by the Fund and/or holdings of cash and cash equivalents. On a less regular basis, each Fund also reserves the right to use borrowings to meet redemption requests, and the Fund may use these methods during both normal and stressed market conditions.

If we determine that it is in the best interest of the Company or a Fund not to pay redemption proceeds in cash, we may distribute to you securities held by the Fund. If requested, we will pay a portion of your redemption(s) in cash (during any 90 day period) up to the lesser of $250,000 or 1% of the net assets of the Fund at the beginning of such period. If a Fund redeems your shares in-kind, you will bear any market risks associated with the securities paid as redemption proceeds. Such in-kind securities may be illiquid and difficult or impossible for a shareholder to sell at a time and at a price that a shareholder would like. Redemptions paid in such securities generally will give rise to income, gain or loss for income tax purposes in the same manner as redemptions paid in cash. In addition, you may incur brokerage costs and a further gain or loss for income tax purposes when you ultimately sell the securities.

Redemption Fees
Shares of the International Opportunity Portfolio redeemed within 30 days of purchase may be subject to a 2% redemption fee, payable to the Fund. The redemption fee is designed to protect the Fund and its remaining shareholders from the effects of short-term trading. The redemption fee is not imposed on redemptions made: (i) through systematic withdrawal/exchange plans, (ii) through asset allocation programs, such as model programs, including redemptions or exchanges that are part of a periodic rebalancing, (iii) of shares received by reinvesting income dividends or capital gain distributions, (iv) through certain collective trust funds or other pooled vehicles, including funds of funds, (v) on behalf of advisory accounts where client allocations are solely at the discretion of the Morgan Stanley Investment Management investment team and (vi) in qualified retirement plans maintained pursuant to Sections 401 (tax-qualified pension, profit sharing, 401(k), money purchase and stock bonus plans), 403 (qualified annuity plans and tax-sheltered annuities) and 457 (deferred compensation plans for employees of tax-exempt entities or governments) of the Code, or certain transactions in other types of retirement accounts, including but not limited to required minimum distributions and redemptions relating to forfeitures, death, disability or qualified domestic relations order. The redemption fee is based on, and deducted from, the redemption proceeds. Each time you redeem or exchange shares of the Fund, the

shares held the longest will be redeemed or exchanged first.

The redemption fee may not be imposed on transactions that occur through certain omnibus accounts at Financial Intermediaries. Certain Financial Intermediaries may not have the ability to assess a redemption fee. Certain Financial Intermediaries may apply different methodologies than those described above in assessing redemption fees, may impose their own redemption fee that may differ from the International Opportunity Portfolio’s redemption fee or may impose certain trading restrictions to deter market-timing and frequent trading. If you invest in a Fund through a Financial Intermediary, please read that Financial Intermediary’s materials carefully to learn about any other restrictions or fees that may apply.

Exchange Privilege

You may exchange shares of any class of a Fund for the same class of shares of any mutual fund (excluding money market funds) sponsored and advised by the Adviser (each, a “Morgan Stanley Multi-Class Fund”), if available, without the imposition of an exchange fee. In addition, you may exchange shares of any class of a Fund for shares of Morgan Stanley U.S. Government Money Market Trust (a “Morgan Stanley Money Market Fund” and, together with the Morgan Stanley Multi-Class Funds, the “Morgan Stanley Funds”), if available, without the imposition of an exchange fee. Exchanges are effected based on the respective NAVs of the applicable Morgan Stanley Fund (subject to any applicable redemption fee) and in accordance with the eligibility requirements of such Fund. To obtain a prospectus for another Morgan Stanley Fund, contact your Financial Intermediary or call Morgan Stanley Shareholder Services at 1-800-869-6397. Prospectuses are also available on our Internet site at www.morganstanley.com/im. If you purchased Fund shares through a Financial Intermediary, certain Morgan Stanley Funds may be unavailable for exchange. Contact your Financial Intermediary to determine which Morgan Stanley Funds are available for exchange.

The current prospectus for each Morgan Stanley Fund describes its investment objective(s), policies and investment minimums, and should be read before investing. Since exchanges are available only into continuously offered Morgan Stanley Funds, exchanges are generally not available into Morgan Stanley Funds or classes of Morgan Stanley Funds that are not currently being offered for purchase.

You can process your exchange by contacting your Financial Intermediary. You may also send exchange requests to the Company’s transfer agent, SS&C GIDS, or Eaton Vance Management, the Fund’s co-transfer agent, by mail to Morgan Stanley Institutional Fund, Inc., c/o SS&C Global Investor and Distribution Solutions, Inc., P.O. Box 219804, Kansas City, MO 64121-9804 or by calling 1-800-869-6397.

You will be subject to the same minimum initial investment and account size as an initial purchase. Your exchange price will be the price calculated at the next Pricing Time after the Morgan Stanley Fund receives your exchange order. The Morgan Stanley Fund, in its sole discretion, may waive the minimum initial investment amount in certain cases. For direct accounts, the check writing privilege is not available for Morgan Stanley Money Market Fund shares you acquire in an exchange from a non-money market fund. If you are investing through a financial advisor, check with your advisor regarding the availability of check writing privileges. An exchange of shares of the International Opportunity Portfolio held for less than 30 days from the date of purchase will be subject to the 2% redemption fee described above. The Fund may terminate or revise the exchange privilege upon required notice or in certain cases without notice. The Fund reserves the right to reject an exchange order for any reason.

If you exchange shares of a Fund for shares of another Morgan Stanley Fund, there are important tax considerations. For tax purposes, the exchange out of a Fund is considered a sale of Fund shares and the exchange into the other fund is considered a purchase. As a result, you may realize a capital gain or loss. You should review the “Taxes” section and consult your own tax professional about the tax consequences of an exchange.

Frequent Purchases and Redemptions of Shares

Frequent purchases and redemptions of shares by Fund shareholders are referred to as “market-timing” or “short-term trading” and may present risks for other shareholders of a Fund, which may include, among other things, diluting the value of a Fund’s shares held by long-term shareholders, interfering with the efficient management of the Fund, increasing brokerage and administrative costs, incurring unwanted taxable gains and forcing the Fund to hold excess levels of cash.

In addition, a Fund is subject to the risk that market-timers and/or short-term traders may take advantage of time zone differences between the foreign markets on which a Fund’s securities trade and the time the Fund’s NAV is calculated (“time-zone arbitrage”). For example, a market-timer may purchase shares of a Fund based on events occurring after foreign market closing prices are established, but before the Fund’s NAV calculation, that are likely to result in higher prices in foreign markets the following day. The market-timer would redeem the Fund’s shares the next day, when the Fund’s share price would reflect the increased prices in foreign markets for a quick profit at the expense of long-term Fund shareholders.

Investments in other types of securities also may be susceptible to short-term trading strategies. These investments include securities that are, among other things, thinly traded, traded infrequently or relatively illiquid, which have the risk that the current market price for the securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take

advantage of these pricing differences (referred to as “price arbitrage”). Investments in certain fixed-income securities may be adversely affected by price arbitrage trading strategies.

The Company discourages and does not accommodate frequent purchases and redemptions of Fund shares by Fund shareholders and the Company’s Board of Directors has adopted policies and procedures with respect to such frequent purchases and redemptions.

The Company’s policies with respect to purchases, redemptions and exchanges of Fund shares are described in the “Shareholder Information—How To Purchase Fund Shares,” “Shareholder Information—General,” “Shareholder Information—How To Redeem Fund Shares” and “Shareholder Information—Exchange Privilege” sections of this Prospectus. Except as described in each of these sections, and with respect to trades that occur through omnibus accounts at Financial Intermediaries, as described below, the Company’s policies regarding frequent trading of Fund shares are applied uniformly to all shareholders. With respect to trades that occur through omnibus accounts at Financial Intermediaries, such as investment advisers, broker-dealers, transfer agents and third-party administrators, the Company (i) has requested assurance that such Financial Intermediaries currently selling Fund shares have in place internal policies and procedures reasonably designed to address market-timing concerns and has instructed such Financial Intermediaries to notify the Fund immediately if they are unable to comply with such policies and procedures and (ii) requires all prospective Financial Intermediaries to agree to cooperate in enforcing the Company’s policies (or, upon prior written approval only, a Financial Intermediary’s own policies) with respect to frequent purchases, redemptions and exchanges of Fund shares.

With respect to trades that occur through omnibus accounts at Financial Intermediaries, to some extent, the Company relies on the Financial Intermediary to monitor frequent short-term trading within a Fund by the Financial Intermediary’s customers and to collect the Fund’s redemption fee, as applicable, from its customers. However, each Fund has entered into agreements with Financial Intermediaries whereby Financial Intermediaries are required to provide certain customer identification and transaction information upon the Fund’s request. A Fund may use this information to help identify and prevent market-timing activity in the Fund. There can be no assurance that a Fund will be able to identify or prevent all market-timing activities.

Dividends and Distributions

Each Fund’s policy is to distribute to shareholders substantially all of its net investment income, if any, in the form of an annual dividend and to distribute net realized capital gains, if any, at least annually.

The Funds automatically reinvest all dividends and distributions in additional shares. However, you may elect to receive distributions in cash by giving written notice to a Fund or your Financial Intermediary or by checking the appropriate box in the Distribution Option section on the New Account Application.

If any distribution check remains uncashed for six months, Morgan Stanley reserves the right to invest the amount represented by the check in Fund shares at the then-current net asset value of the Fund and all future distributions will be reinvested. For accounts held directly with a Fund’s transfer agent for which the shareholder has elected to receive distributions via check, any distribution (dividend or capital gain) under $10.00 is automatically reinvested in additional shares regardless of your elected distribution option.

Inactive Accounts and Risk of Escheatment

In accordance with state “unclaimed property” laws, your Fund shares may legally be considered abandoned and required to be transferred to the relevant state (also known as “escheatment”) under various circumstances. These circumstances, which vary by state, can include inactivity (e.g., no owner-initiated contact for a certain period), returned mail (e.g., when mail sent to a shareholder is returned by the post office as undeliverable), uncashed checks or a combination of these. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Fund or your Financial Intermediary. Since states’ statutory requirements regarding inactivity differ, it is important to regularly contact your Financial Intermediary or the Fund’s transfer agent. The process described above, and the application of state escheatment laws, may vary by state and/or depending on how shareholders hold their shares in the Fund.

It is your responsibility to ensure that you maintain a valid mailing address for your account, keep your account active by contacting your Financial Intermediary or the Fund’s transfer agent (e.g., by mail or telephone), and promptly cash all checks for dividends, capital gains and redemptions. Neither the Fund nor the Adviser will be liable to shareholders or their representatives for good faith compliance with escheatment laws.

For more information, please contact us at 1-888-378-1630.

Taxes

The dividends and distributions you receive from a Fund may be subject to federal, state and local taxation, depending on your tax situation. The tax treatment of dividends and distributions is the same whether or not you reinvest them. Dividends paid by a Fund that are attributable to “qualified dividends” received by the Fund may be taxed at reduced rates to individual shareholders (either 15% or 20%, depending on whether the individual’s income exceeds certain threshold amounts), if certain requirements are met by the Fund and the shareholders. “Qualified dividends” include dividends distributed by U.S. and certain foreign corporations

(generally, corporations incorporated in a possession of the United States, some corporations eligible for treaty benefits under a treaty with the United States and corporations whose stock with respect to which such dividend is paid is readily tradable on an established securities market in the United States, but not including passive foreign investment companies). Dividends paid by a Fund not attributable to “qualified dividends” received by a Fund, including distributions of short-term capital gains, will generally be taxed at normal tax rates applicable to ordinary income. The maximum individual rate applicable to long-term capital gains (including capital gain dividends received from the Fund) is generally either 15% or 20%, depending on whether the individual’s income exceeds certain threshold amounts. A Fund may be able to pass through to you a credit for foreign income taxes it pays. The Fund will tell you annually how to treat dividends and distributions.

If certain holding period requirements are met, corporate shareholders may be entitled to a dividends-received deduction for the portion of dividends they receive which are attributable to dividends received by a Fund from U.S. corporations.

If you redeem shares of a Fund, you may be subject to tax on any gains you earn based on your holding period for the shares and your marginal tax rate. An exchange of shares of a Fund for shares of another portfolio is treated for tax purposes as a sale of the original shares in the Fund, followed by the purchase of shares in the other portfolio. Conversions of shares between classes will not result in taxation.

If you buy shares of a Fund before a distribution, you will be subject to tax on the entire amount of the taxable distribution you receive. Distributions are taxable to you even if they are paid from income or gain earned by a Fund before your investment (and thus were included in the price you paid for your Fund shares).

An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) 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.

Shareholders who are not citizens or residents of the United States and certain foreign entities will generally be subject to withholding of U.S. tax of 30% on distributions made by a Fund of investment income and short-term capital gains.

The Funds are required to withhold U.S. tax (at a 30% rate) on payments of taxable dividends made to certain non-U.S. entities that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. Shareholders may be requested to provide additional information to the Funds to enable the Funds to determine whether withholding is required.

The Funds (or their administrative agent) are required to report to the U.S. Internal Revenue Service (“IRS”) and furnish to Fund shareholders the cost basis information for sale transactions of shares purchased on or after January 1, 2012. Shareholders may elect to have one of several cost basis methods applied to their account when calculating the cost basis of shares sold, including average cost, FIFO (“first-in, first-out”) or some other specific identification method. Unless you instruct otherwise, each Fund will use average cost as its default cost basis method, and will treat sales as first coming from shares purchased prior to January 1, 2012. If average cost is used for the first sale of Fund shares covered by these rules, the shareholder may only use an alternative cost basis method for shares purchased prospectively. Fund shareholders should consult with their tax advisors to determine the best cost basis method for their tax situation.

The Funds may be required to withhold U.S. federal income tax (currently, at a rate of 24%) (“backup withholding”) from all taxable distributions payable to (1) any shareholder who fails to furnish the Funds with its correct taxpayer identification number or a certificate that the shareholder is exempt from backup withholding, and (2) any shareholder with respect to whom the IRS notifies a Fund that the shareholder has failed to properly report certain interest and dividend income to the IRS and to respond to notices to that effect. An individual’s taxpayer identification number is his or her social security number. The 24% backup withholding tax is not an additional tax and may be credited against a taxpayer’s regular federal income tax liability.

Because each investor’s tax circumstances are unique and the tax laws may change, you should consult your tax advisor about your investment.

Potential Conflicts of Interest

As a diversified global financial services firm, Morgan Stanley, the parent company of the Adviser, engages in a broad spectrum of activities, including financial advisory services, investment management activities, lending, commercial banking, sponsoring and managing private investment funds, engaging in broker-dealer transactions and principal securities, commodities and foreign exchange transactions, research publication and other activities. In the ordinary course of its business, Morgan Stanley is a full-service investment banking and financial services firm and therefore engages in activities where Morgan Stanley’s interests or the interests of its clients may conflict with the interests of a Fund. Morgan Stanley advises clients and sponsors, manages or advises other investment funds and investment programs, accounts and businesses (collectively, together with any new or successor funds, programs, accounts

or businesses, the ‘‘Affiliated Investment Accounts’’) with a wide variety of investment objectives that in some instances may overlap or conflict with a Fund’s investment objectives and present conflicts of interest. In addition, Morgan Stanley may also from time to time create new or successor Affiliated Investment Accounts that may compete with a Fund and present similar conflicts of interest. The discussion below enumerates certain actual, apparent and potential conflicts of interest. There is no assurance that conflicts of interest will be resolved in favor of Fund shareholders and, in fact, they may not be. Conflicts of interest not described below may also exist.

For more information about conflicts of interest, see the section entitled “Potential Conflicts of Interest” in the SAI.

Material Nonpublic Information. It is expected that confidential or material nonpublic information regarding an investment or potential investment opportunity may become available to the Adviser. If such information becomes available, the Adviser may be precluded (including by applicable law or internal policies or procedures) from pursuing an investment or disposition opportunity with respect to such investment or investment opportunity. Morgan Stanley has established certain information barriers and other policies to address the sharing of information between different businesses within Morgan Stanley. In limited circumstances, however, including for purposes of managing business and reputational risk, and subject to policies and procedures and any applicable regulations, personnel, including personnel of the investment adviser, on one side of an information barrier may have access to information and personnel on the other side of the information barrier through “wall crossings.” The Adviser faces conflicts of interest in determining whether to engage in such wall crossings. Information obtained in connection with such wall crossings may limit or restrict the ability of the Adviser to engage in or otherwise effect transactions on behalf of the Funds (including purchasing or selling securities that the Adviser may otherwise have purchased or sold for a Fund in the absence of a wall crossing).

Investments by Morgan Stanley and its Affiliated Investment Accounts. In serving in multiple capacities to Affiliated Investment Accounts, Morgan Stanley, including the Adviser and the Investment team, may have obligations to other clients or investors in Affiliated Investment Accounts, the fulfillment of which may not be in the best interests of a Fund or its shareholders. A Fund’s investment objectives may overlap with the investment objectives of certain Affiliated Investment Accounts. As a result, the members of an Investment team may face conflicts in the allocation of investment opportunities among a Fund and other investment funds, programs, accounts and businesses advised by or affiliated with the Adviser. Certain Affiliated Investment Accounts may provide for higher management or incentive fees or greater expense reimbursements or overhead allocations, all of which may contribute to this conflict of interest and create an incentive for the Adviser to favor such other accounts. To seek to reduce potential conflicts of interest and to attempt to allocate such investment opportunities in a fair and equitable manner, the Adviser has implemented allocation policies and procedures. These policies and procedures are intended to give all clients of the Adviser, including the Funds, fair access to investment opportunities consistent with the requirements of organizational documents, investment strategies, applicable laws and regulations, and the fiduciary duties of the Adviser.

Payments to Broker-Dealers and Other Financial Intermediaries. The Adviser and/or the Distributor may pay compensation, out of their own funds and not as an expense of a Fund, to certain Financial Intermediaries (which may include affiliates of the Adviser and Distributor), including recordkeepers and administrators of various deferred compensation plans, in connection with the sale, distribution, marketing and retention of shares of the Fund and/or shareholder servicing. The prospect of receiving, or the receipt of, additional compensation, as described above, by Financial Intermediaries may provide such Financial Intermediaries and their financial advisors and other salespersons with an incentive to favor sales of shares of a Fund over other investment options with respect to which these Financial Intermediaries do not receive additional compensation (or receives lower levels of additional compensation). These payment arrangements, however, will not change the price that an investor pays for shares of a Fund or the amount that the Fund receives to invest on behalf of an investor. Investors may wish to take such payment arrangements into account when considering and evaluating any recommendations relating to Fund shares and should review carefully any disclosures provided by Financial Intermediaries as to their compensation. In addition, in certain circumstances, the Adviser restricts, limits or reduces the amount of a Fund’s investment, or restricts the type of governance or voting rights it acquires or exercises, where the Fund (potentially together with Morgan Stanley) exceeds a certain ownership interest, or possesses certain degrees of voting or control or has other interests.

Morgan Stanley Trading and Principal Investing Activities. Notwithstanding anything to the contrary herein, Morgan Stanley will generally conduct its sales and trading businesses, publish research and analysis, and render investment advice without regard for a Fund’s holdings, although these activities could have an adverse impact on the value of one or more of the Fund’s investments, or could cause Morgan Stanley to have an interest in one or more portfolio investments that is different from, and potentially adverse to, that of a Fund.

Morgan Stanley’s Investment Banking and Other Commercial Activities. Morgan Stanley advises clients on a variety of mergers, acquisitions, restructuring, bankruptcy and financing transactions. Morgan Stanley may act as an advisor to clients, including other investment funds that may compete with a Fund and with respect to investments that a Fund may hold. Morgan Stanley may give advice and take action with respect to any of its clients or proprietary accounts that may differ from the advice given, or may involve an action of a different timing or nature than the action taken, by a Fund. Morgan Stanley may give advice and provide recommendations to persons competing with a Fund and/or any of a Fund’s investments that are contrary to the Fund’s best interests
