Investment Objective

Calvert US Select Equity ETF (the “Fund”) seeks to provide long-term capital appreciation.

Fees and Expenses

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

Annual Fund Operating Expenses¹ (expenses that you pay each year as a percentage of the value of your investment)


Management Fee¹	0.29%
Other Expenses²	0.00%
Total Annual Fund Operating Expenses	0.29%

[The Fund’s management agreement provides that the Fund’s “Adviser,” Morgan Stanley Investment Management Inc., will pay substantially all expenses of the Fund (including expenses of Morgan Stanley ETF Trust (the “Trust”) relating to the Fund), except for the distribution fees, if any, brokerage expenses, acquired fund fees and expenses, taxes, interest, litigation expenses, and other extraordinary expenses, including the costs of proxies, not incurred in the ordinary course of the Fund’s business.]

2	[Other Expenses have been estimated for the current fiscal year.]

Example

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling shares of the Fund.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell your shares at the end of those periods. The example also assumes 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:


	1 Year	3 Years
	$30	$93

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. Because the Fund had not commenced operations as of the most recent fiscal year end, no portfolio turnover rate is available for the Fund.

Principal Investment Strategies

Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in the equity securities of U.S. issuers. This policy may be changed without shareholder approval; however, shareholders would be notified upon 60 days’ notice in writing of any changes.

The Fund is actively managed, not designed to track a benchmark, and therefore not constrained by the composition of a benchmark.

The Fund primarily invests in the equity securities of large capitalization U.S. issuers that are involved in economic activities that address global environmental or societal challenges that relate to areas such as environmental sustainability and resource efficiency, diversity, equity and inclusion, respect for human rights, product responsibility, human capital management and accountable governance and transparent operations, or are leaders in managing financially material environmental or social risks and opportunities, such as carbon emission management and diversity, equity and inclusion. Economic activities that address environmental and/or societal challenges vary based on the respective industry a company operates in, but examples may include: providing access to finance to demographics that are typically excluded from traditional financing channels, providing affordable and accessible healthy food and other products, growing electric vehicle sales and strategy, and efficient management of natural resources. As described below, the Adviser utilizes a quantitative and qualitative research process that applies the Calvert Principles for Responsible Investment (a copy of which is included as an appendix to the Fund’s prospectus) to define the investment universe for the Fund. Calvert Research and Management (“Calvert”), on behalf of the Adviser, may engage with company management regarding financially material environmental, social and governance (“ESG”) issues in pursuit of improving environmental and social outcomes. The Adviser gives due consideration to the relevance and potential materiality of sustainability risks for a particular investment opportunity or for the portfolio as a whole in the context of the investment objective and intended time horizon for holding a particular security. In order to mitigate Responsible Investing risks, the Adviser may (i) determine not to hold, determine

to sell or otherwise determine to underweight a security relative to the Fund’s benchmark, the Russell 1000® Index; (ii) engage Calvert to discuss potential engagement with company management on its material ESG risks or opportunities (e.g., climate change, diversity, labor and human rights and ESG disclosure); or (iii) make other adjustments to the Fund’s portfolio.

Through a qualitative and quantitative process (the “Selection Process”), the Adviser seeks to identify companies that are performing in the top 20-40% of their peer group with respect to environmental or social factors determined to be financially material to the company based on Calvert and/or the Adviser’s proprietary research (each, a “Select Company” and collectively, the “Select Companies”). A company may also be determined to be a Select Company based on leadership or significant improvement of such company’s financially material environmental or social risks or opportunities. Once the Fund’s investment universe of Select Companies (the “Investment Universe”) has been established, the Adviser then seeks to optimize the Fund’s Investment Universe by selecting and weighting Select Companies that have better diversity and lower carbon risk, while also minimizing factor risks relative to the Russell 1000® Index (the “Optimization Process”). The Adviser seeks to ensure that at least 90% of the companies in the Fund’s portfolio are reviewed via the Selection Process.

In managing the Fund, the Adviser also takes into account the long-term carbon reduction objectives of the Paris Agreement, an international treaty on climate change with the goal of limiting global warming to well below 2 degrees Celsius, preferably to 1.5 degrees. The Adviser measures a company’s carbon footprint by its weighted average carbon intensity, which is defined as metric tons of greenhouse gas emissions per $1 million of revenue. The Fund seeks to maintain a portfolio with an overall carbon footprint that is substantially lower than the carbon footprint of the Russell 1000® Index. Individual securities held by the Fund, however, may have carbon footprints that are higher than the average carbon footprint of the Russell 1000® Index and/or the carbon footprint of certain Russell 1000® Index constituents. The long-term carbon reduction objectives of the Paris Agreement may warrant the Adviser to revise the targeted range of carbon reduction by companies it seeks to invest in over time. ESG analysis is determined by Calvert, using a combination of third party and customized ESG data as a base, and having regard to ESG themes such as environmental sustainability and resource efficiency, diversity, equity and inclusion, respect for human rights, product responsibility, human capital management and accountable governance and transparent operations.

In addition, the Fund will seek to maintain higher levels of diversity level than the Russell 1000® Index as measured by weighted average number of women at the board level. The Adviser obtains board gender diversity data from third party vendors, which provide data on the number of women on boards at the issuer level. The Adviser collects this data for all names in its investment universe for which data is available and calculates the weighted average for the Fund and the Russell 1000® Index.

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

Although the Fund’s ESG factors and responsible investing criteria are typically considered with respect to each company or issuer in which the Fund invests, other factors may be considered by the portfolio management team. In assessing investments, Calvert generally focuses on the ESG factors and responsible investing criteria relevant to the issuer’s operations, and an issuer may be acceptable for investment based primarily on such assessment. As a result, securities may be deemed suitable for investment even if the issuer does not operate in accordance with all elements of the Fund’s ESG factors and responsible investing criteria. For instance, the Fund may also invest in issuers that Calvert believes are likely to operate in a manner consistent with the Calvert Principles pending Calvert’s engagement activity with such issuer. Additionally, the Fund may invest in cash, money market instruments and ETFs. Such investments will generally not be subject to the Fund’s responsible investment analysis and will not be required to be consistent with the Fund’s ESG factors and responsible investment criteria otherwise applicable to investments made by the Fund. In addition, ETFs in which the Fund may invest may hold securities of issuers that do not operate in accordance with the Fund’s ESG factors and responsible investment criteria.

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 and political conditions.

•

Responsible Investing. Investing primarily in responsible investments carries the risk that, under certain market conditions, the Fund may underperform funds that do not utilize a responsible investment strategy. The application of responsible investment criteria may affect the Fund’s exposure to certain sectors or types of investments, and may impact the Fund’s relative investment

performance depending on whether such sectors or investments are in or out of favor in the market. An investment’s ESG performance, or Calvert’s and/or the Adviser’s assessment of such performance may change over time, which could cause the Fund to temporarily hold securities that do not comply with the Fund’s responsible investment criteria. In evaluating an investment, Calvert and the Adviser are dependent upon information and data that may be incomplete, inaccurate or unavailable, which could adversely affect the analysis of the ESG factors relevant to a particular investment. Successful application of the Fund’s responsible investment strategy will depend on Calvert’s and/or the Adviser’s skill in properly identifying and analyzing material ESG issues.

•

Liquidity. The Fund may make investments that are illiquid or restricted or that may become 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 meet cash needs, it may be forced to sell the security at a loss or for less than its fair value.

•

Market and Geopolitical Risk. The value of your investment in the Fund is based on the values of the Fund’s investments, which may change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. These events may be sudden and unexpected, and could adversely affect the liquidity of the Fund’s investments, which may in turn impact valuation, the Fund’s ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other conditions and events (such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest) 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.

•

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

•

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant creates or redeems, shares may trade at a discount to net asset value (“NAV”) and possibly face trading halts and/or delisting.

•

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.

•

Trading Risk. The market prices of shares are expected to fluctuate, in some cases materially, in response to changes in the Fund’s NAV, the intra-day value of the Fund’s holdings, and supply and demand for shares. The Adviser cannot predict whether shares will trade above, below or at their NAV. Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares (including through a trading halt), as well as other factors, may result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of the Fund’s holdings. Buying or selling shares in the secondary market may require paying brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost when seeking to buy or sell relatively small amounts of shares. In addition, the market price of shares, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The spread of a Fund’s shares varies over time based on the Fund’s trading volume and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decrease.

•

New Fund Risk. A new fund’s performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new funds may not attract sufficient assets to achieve investment and trading efficiencies.

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.

Purchase and Sale of Fund Shares

Individual shares of the Fund may only be purchased and sold in secondary market transactions through a broker or dealer at market price. Because shares trade at market prices, rather than NAV, shares of the Fund may trade at a price greater than NAV (i.e., a premium) or less than NAV (i.e., a discount).

You may incur costs attributable to the difference between the highest price a buyer is willing to pay for shares (bid) and the lowest price a seller is willing to accept for shares (ask) (the “bid-ask spread”) when buying or selling shares in the secondary market.

Recent information, including information about the Fund’s NAV, market price, premiums and discounts, and bid-ask spreads (when available), will be available on the Fund’s website at www.calvert.com.

Tax Information

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

Payments to Broker-Dealers and Other Financial Intermediaries

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

Investment Objective

The Fund’s investment objective is to seek to provide long-term capital appreciation.

The Fund’s investment objective may be changed by the Trust’s Board of Trustees 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

The Fund seeks to achieve its investment objective by primarily investing in U.S. equity securities, including common stock, and preferred stock of companies that are involved in economic activities that address global environmental or societal challenges that relate to areas such as environmental sustainability and resource efficiency, diversity, equity and inclusion, respect for human rights, product responsibility, human capital management and accountable governance and transparent operations, or are leaders in managing financially material environmental or social risks and opportunities, such as carbon emission management and diversity, equity and inclusion.

Process

The Fund is actively managed, not designed to track a benchmark, and therefore not constrained by the composition of a benchmark.

The Fund primarily invests in the equity securities of large capitalization U.S. issuers that are involved in economic activities that address global environmental or societal challenges that relate to areas such as environmental sustainability and resource efficiency, diversity, equity and inclusion, respect for human rights, product responsibility, human capital management and accountable governance and transparent operations, or are leaders in managing financially material environmental or social risks and opportunities, such as carbon emission management and diversity, equity and inclusion. Economic activities that address environmental and/or societal challenges vary based on the respective industry a company operates in, but examples may include: providing access to finance to demographics that are typically excluded from traditional financing channels, providing affordable and accessible healthy food and other products, growing electric vehicle sales and strategy, and efficient management of natural resources. The Adviser incorporates company identification, portfolio optimization, and corporate engagement in implementing the Fund’s investment strategy. The Adviser utilizes a quantitative and qualitative research process regarding ESG factors for each potential investment that applies the Calvert Principles for Responsible Investment (a copy of which is included as an appendix to this prospectus) to define the investment universe for the Fund.

Through a qualitative and quantitative process (the “Selection Process”), the Adviser seeks to identify companies that are performing in the top 20-40% of their peer group with respect to environmental or social factors determined to be financially material to the company based on Calvert and/or the Adviser’s proprietary research (each, a “Select Company” and collectively, the “Select Companies”). A company may also be determined to be a Select Company based on leadership or significant improvement of such company’s financially material environmental or social risks or opportunities. Once the Fund’s investment universe of Select Companies (the “Investment Universe”) has been established, the Adviser then seeks to optimize the Fund’s Investment Universe by selecting and weighting Select companies that have better diversity and lower carbon risk, while also minimizing factor risks relative to the Russell 1000® Index (the “Optimization Process”). The Adviser seeks to ensure that at least 90% of the companies in the Fund’s portfolio are reviewed via the Selection Process.

Calvert, on behalf of the Adviser, may engage with company management regarding financially material ESG issues in pursuit of improving environmental and social outcomes. The Adviser gives due consideration to the relevance and potential materiality of sustainability risks for a particular investment opportunity or for the portfolio as a whole in the context of the investment objective and intended time horizon for holding a particular security. In order to mitigate Responsible Investing risks, the Adviser may (i) determine not to hold, determine to sell or otherwise determine to underweight a security relative to the Fund’s benchmark, the Russell 1000® Index; (ii) engage Calvert to discuss potential engagement with company management on its material ESG risks or opportunities (e.g., climate change, diversity, labor and human rights and ESG disclosure); or (iii) make other adjustments to the Fund’s portfolio.

revise the targeted range of carbon reduction by companies it seeks to invest in over time. ESG analysis is determined by Calvert, using a combination of third party and customized ESG data as a base, and having regard to ESG themes such as environmental sustainability and resource efficiency, diversity, equity and inclusion, respect for human rights, product responsibility, human capital management and accountable governance and transparent operations.

The Fund may invest up to 20% of its net assets in the securities of non-U.S. issuers. The Fund may invest in depositary receipts (such as American Depository Receipts (ADRs), Global Depositary Receipts (GDRs), and European Depository Receipts (EDRs)), which evidence ownership of shares of a foreign issuer and are alternatives to directly purchasing the underlying foreign securities in their national markets and currencies.

Related Performance Information of Composite

The Fund has recently commenced operations and has no performance history. An affiliate of the Adviser, Calvert, manages a composite (the “Composite”) that consists of an account and a mutual fund managed by two of the portfolio managers that each have a substantially similar investment objective, policies and investment strategies as the Fund (the “Composite Accounts”) and the table below provides supplemental performance information for the Composite. The performance of the Composite is net of fees and expenses, which, depending on the account may be lower or higher than those charged to the Fund. Since fees, commissions and taxes may differ for the Composite and the Fund, performance data for identical periods may differ. The Composite reflects transaction costs, but does not reflect (i) custody fees, Rule 12b-1 fees or other expenses normally paid by mutual funds that are unrelated to the investment management services provided by an adviser or (ii) a deduction of any applicable sales load(s) of the Composite Account. If these expenses were included, returns would be lower. The Composite performance information does not represent the performance of the Fund. It is provided to illustrate the past performance of accounts advised by an affiliate of the Adviser. The portfolio managers for the Composite Accounts are two of the portfolio managers listed for the Fund. These two individuals have sole or joint responsibility for managing the Composite Accounts. These two individuals have ultimate decision-making authority for both the Composite Accounts and the Fund.

The historical performance data for the Composite should not be considered a substitute for the Fund’s performance and should not be considered an indication of the Fund’s future performance. You should not assume that the Fund will have the same performance as the Composite. An investment in the Fund can lose value. Although the Fund and the Composite Accounts have a substantially similar investment objective, policies and investment strategies, differences in asset size and cash flows, among other things, may result in differences in security selection, relative weightings or differences in the price paid for certain securities. As such, the investments held by the Fund may not be identical to the investments held by the Composite Accounts and the future performance of the Fund will differ from the performance of the Composite.

One of the Composite Accounts in the Composite is not subject to certain investment limitations, diversification requirements and other restrictions imposed on registered investment companies, such as the Fund, by the 1940 Act and the Internal Revenue Code of 1986, as amended, which, if applicable, may have adversely affected the performance of the Composite.


This section discusses additional information relating to the Fund’s investment strategies, other types of investments that the Fund may make and related risk factors. The Fund’s 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.

Economies and financial markets throughout the world have experienced periods of increased volatility, uncertainty and distress and disruption to consumer demand, economic output and supply chains as a result of conditions associated with the COVID-19 pandemic. 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 duration and extent of COVID-19 and associated economic and market conditions and uncertainty over the long term cannot be reasonably estimated at this time. The ultimate impact of COVID-19 and the extent to which the associated conditions impact the Fund will also depend on future developments, which are highly uncertain, difficult to accurately predict and subject to change at any time.

The name, investment objective and policies of the Fund is similar to another fund advised by the Adviser or its affiliates. However, the investment results of the Fund may be higher or lower than, and there is no guarantee that the investment results of the Fund will be comparable to, any other funds. A new fund or a fund with fewer assets under management may be more significantly affected by purchases and redemptions of its Creation Units (as defined below) than a fund with relatively greater assets under management would be affected by purchases and redemptions of its shares. As compared to a larger fund, a new or smaller fund is more likely to sell a comparatively large portion of its portfolio to meet significant Creation Unit redemptions or invest a comparatively large amount of cash to facilitate Creation Unit purchases, in each case when the fund otherwise would not seek to do so. Such transactions may cause funds to make investment decisions at inopportune times or prices or miss attractive investment opportunities. Such transactions may also accelerate the realization of taxable income if sales of securities resulted in gains and the fund redeems Creation Units for cash, or otherwise cause a fund to perform differently than intended. While such risks may apply to funds of any size, such risks are heightened in funds with fewer assets under management. In addition, new funds may not be able to fully implement their investment strategy immediately upon commencing investment operations, which could reduce investment 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, limited partnership interests and other specialty securities having equity features. The Fund 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.

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.

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. Although stock prices can rebound, there is no assurance that values will return to previous levels

Market and Geopolitical Risk

The value of your investment in the Fund is based on the values of the Fund’s investments, which may change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. 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 financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. 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, health emergencies (such as epidemics and pandemics), terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, health emergencies, social and political discord 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 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., the novel coronavirus outbreak, epidemics and other pandemics), terrorism, conflicts and social unrest, 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.

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.

Certain countries and regulatory bodies use negative interest rates as a monetary policy tool to encourage economic growth during periods of deflation. In a negative interest rate environment, debt instruments may trade at negative yields, which means the purchaser of the instrument may receive at maturity less than the total amount invested. In addition, in a negative interest rate environment, if a bank charges negative interest rates, instead of receiving interest on deposits, a depositor must pay the bank fees to keep money with the bank. To the extent the Fund holds a debt instrument or has a bank deposit with a negative interest rate, the Fund would generate a negative return on that investment.

Responsible Investing

Investing primarily in responsible investments carries the risk that, under certain market conditions, the Fund may underperform funds that do not utilize a responsible investment strategy. The application of responsible investment criteria may affect the Fund’s exposure to certain sectors or types of investments, and may impact the Fund’s relative investment performance depending on whether such sectors or investments are in or out of favor in the market. An investment’s ESG performance, or Calvert’s and/or the Adviser’s assessment of such performance may change over time, which could cause the Fund to temporarily hold securities that do not comply with the Fund’s responsible investment criteria. In evaluating an investment, Calvert and the Adviser are dependent upon information and data that may be incomplete, inaccurate or unavailable, which could adversely affect the analysis of the ESG factors relevant to a particular investment. Successful application of the Fund’s responsible investment strategy will depend on Calvert’s and/or the Adviser’s skill in properly identifying and analyzing material ESG issues. Regulatory changes or interpretations regarding the definitions and/or use of ESG criteria could have a material adverse effect on the Fund’s ability to invest in accordance with its ESG strategy. Socially responsible norms differ by country and region, and a company’s ESG practices or Calvert and/or the Adviser’s assessment of such may change over time and there is a risk that the Adviser may incorrectly assess a company’s ESG practices. The Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

Foreign Investing

To the extent that the 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 Fund’s 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 the 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.

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 ongoing 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 the 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, 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 the 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 the 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. The 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 the Fund and increased transaction costs, impair the Fund’s ability to purchase or sell foreign securities or transfer the Fund’s assets back into the United States, or otherwise adversely affect the 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 the 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 the 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. The Fund’s investments in foreign securities are subject to economic sanctions and trade laws 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 the Fund from investing in certain foreign securities. In addition, economic sanctions could prohibit the 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 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, increase the Fund’s transaction costs, make the Fund’s investments more difficult to value or impair the 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 the Fund.

Liquidity

The Fund may make investments that are illiquid or restricted or that may become 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 meet cash needs, it may be forced to sell the security at a loss or for less than its fair value.

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

Foreign Currency Forward Exchange Contracts

In connection with its investments in foreign securities, the Fund 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 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 Fund’s exposure to currency exchange rates and could result in losses to the Fund 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 Fund’s 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 Fund’s 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 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.

Derivatives

The Fund may, but is not required to, use derivative instruments for a variety of purposes, including hedging, risk management, portfolio management or 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. A derivative instrument often has risks similar to its underlying asset and may have additional risks, including imperfect correlation between the value of the derivative and the underlying asset, risks of default by the counterparty to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative instrument relates, risks that the transactions may not be liquid and risks arising from margin requirements. 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 derivative 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 to satisfy its obligations or to meet earmarking or segregation requirements, pursuant to applicable SEC rules and regulations, 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.

Exchange-Traded Funds

The Fund may invest in exchange-traded funds (“ETFs”). 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, the 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 the Fund and indirectly bear the expenses of the Fund’s investments in ETFs with respect to investments in ETFs.

Large Shareholder Transactions Risk

The Fund may experience adverse effects when certain shareholders purchase or redeem large amounts of shares of the Fund. In addition, a third party investor, the Adviser or an affiliate of the Adviser, an authorized participant, a lead market maker, or another entity (i.e., a seed investor) may invest in the Fund and hold its investment solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. Any such investment may be held for a limited period of time. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing 3 requirements. Such larger than normal redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the 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 the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Although large shareholder transactions may be more frequent under certain circumstances, the Fund is generally subject to the risk that shareholders can purchase or redeem a significant percentage of Fund shares at any time. In addition, transactions by large shareholders may account for a large percentage of the trading volume on NYSE Arca and may, therefore, have a material upward or downward effect on the market price of the shares.

Counterparty Risk

A financial institution or other counterparty with whom the Fund does business (such as trading, securities lending or as a derivatives counterparty), or that underwrites, distributes or guarantees any instruments that the Fund owns or is otherwise exposed to, may decline in financial condition and become unable to honor its commitments. This could cause the value of Fund shares to decline or could delay the return or delivery of collateral or other assets to the Fund. Counterparty risk is increased for contracts with longer maturities.

Securities Lending

The Fund may lend its portfolio securities to broker-dealers and other institutional borrowers. During the existence of a loan, the Fund will continue to receive the equivalent of the interest paid by the issuer on the securities loaned, or all or a portion of the interest on investment of the collateral, if any. The Fund may pay lending fees to such borrowers. Loans will only be made to firms that have been approved by the Adviser, and the Adviser or the securities lending agent will periodically monitor the financial condition of such firms while such loans are outstanding. Securities loans will only be made when the Adviser believes that the expected returns, net of expenses, justify the attendant risks. Securities loans currently are required to be secured continuously by collateral in cash, cash equivalents (such as money market instruments) or other liquid securities held by the custodian and maintained in an amount at least equal to the market value of the securities loaned. The Fund may engage in securities lending to generate income. Upon return of the loaned securities, the Fund would be required to return the related collateral to the borrower and may be required to liquidate portfolio securities in order to do so. The Fund may lend up to one-third of the value of its total assets or such other amount as may be permitted by law.

As with other extensions of credit, there are risks of delay in recovery or even loss of rights in the securities loaned if the borrower of the securities fails financially. To the extent that the portfolio securities acquired with such collateral have decreased in value, it may result in the Fund realizing a loss at a time when it would not otherwise do so. As such, securities lending may introduce leverage into the Fund. The Fund also may incur losses if the returns on securities that it acquires with cash collateral are less than the applicable rebate rates paid to borrowers and related administrative costs.

Trading Risk

Shares are listed for trading on NYSE Arca and are bought and sold in the secondary market at market prices. The market prices of shares are expected to fluctuate, in some cases materially, in response to changes in the Fund’s NAV, the intra-day value of the Fund’s

holdings, and supply and demand for shares. The Adviser cannot predict whether shares will trade above, below or at their NAV. Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares (including through a trading halt), as well as other factors, may result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of the Fund’s holdings. During such periods, you may incur significant losses if you sell your shares.

Buying or selling shares in the secondary market may require paying brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost when seeking to buy or sell relatively small amounts of shares. In addition, the market price of shares, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The spread of a Fund’s shares varies over time based on the Fund’s trading volume and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decrease.

Trading in shares on NYSE Arca may be halted due to market conditions or for reasons that, in the view of NYSE Arca, make trading in shares inadvisable. In addition, trading in shares on NYSE Arca is subject to trading halts caused by extraordinary market volatility pursuant to NYSE Arca “circuit breaker” rules. If a trading halt or unanticipated closing of the exchange occurs, a shareholder may be unable to purchase or sell shares. There can be no assurance that the requirements of NYSE Arca necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Authorized Participant Concentration Risk

Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant creates or redeems, shares may trade at a discount to NAV and possibly face trading halts and/or delisting.

Cybersecurity Risk

With the increased use of technologies such as the internet to conduct business, the Fund, authorized participants, service providers and the relevant listing exchange are susceptible to operational, information security and related “cyber” risks both directly and through the service providers. Similar types of cybersecurity risks are also present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers and may cause the Fund’s investment in such issuers to lose value. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyberattacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Recently, geopolitical tensions may have increased the scale and sophistication of deliberate attacks, particularly those from nation-states or from entities with nation-state backing.

Cybersecurity failures by, or breaches of, the systems of the Fund’s adviser, distributor and other service providers (including, but not limited to, index and benchmark providers, fund accountants, custodians, transfer agents and administrators), market makers, authorized participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyberattacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible, inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, that prevention and remediation efforts will not be successful or that cyberattacks will go undetected. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, market makers or authorized participants. The Fund and its shareholders could be negatively impacted as a result.

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.

Investment Selection Process

Calvert seeks to identify issuers that manage ESG risk exposures adequately and that are not exposed to excessive ESG risk through their principal business activities. Issuers are analyzed using The Calvert Principles for Responsible Investment (included as Appendix A to this Prospectus), a framework for considering ESG factors. Each issuer is evaluated relative to an appropriate peer group based on financially material ESG factors as determined by Calvert. Calvert’s evaluation of a particular security’s responsible investing characteristics generally involves both quantitative and qualitative analysis. In assessing investments, Calvert generally focuses on the ESG factors relevant to the issuer’s operations, and an issuer may be acceptable for investment based primarily on such assessment. Securities may be deemed suitable for investment even if the issuer does not operate in accordance with all elements of the Fund’s responsible investing criteria. The Fund may also invest in issuers that Calvert believes are likely to operate in accordance with the Principles pending Calvert’s engagement activity with such issuer. In assessing issuers for which quantitative data is limited, subjective judgments may serve as the primary basis for Calvert’s evaluation. The responsible investing criteria of the Fund may be changed by the Board without shareholder approval.

As described above, and in the SAI, the Fund may invest in cash, money market instruments and ETFs. Such investments will generally not be subject to responsible investment analysis and will not be required to be consistent with the responsible investment criteria otherwise applicable to investments made by the Fund. In addition, ETFs in which the Fund may invest may hold securities of issuers that do not operate in accordance with the Fund’s responsible investment criteria.

Shareholder Advocacy and Corporate Responsibility

The Adviser has engaged Calvert to vote proxies consistent with Calvert’s Proxy Voting Policies and Procedures and Global Proxy Voting Guidelines (the “Proxy Voting Policies”). The Adviser has also engaged Calvert to seek to actively engage with issuers. Calvert uses strategic engagement and shareholder advocacy to encourage positive change in companies. Calvert’s activities may include, but are not limited to:

Direct Dialogue with Company Management. Calvert, or its agent, may initiate dialogue with management through phone calls, letters and in-person meetings. Through its interaction, Calvert seeks to learn about management’s successes and challenges and to press for improvement on issues of concern.

Proxy Voting. As a shareholder of the companies in its portfolio, the Fund typically has an opportunity each year to express its views on issues of corporate governance and sustainability at annual stockholder meetings. Calvert votes proxies consistent with the Proxy Voting Policies attached to the SAI.

Shareholder Resolutions. Calvert may propose that companies submit resolutions to their shareholders on a variety of ESG issues. Calvert believes that submitting shareholder resolutions may help establish dialogue with management and encourage companies to take action.

Adviser

Morgan Stanley Investment Management Inc., with principal offices at 522 Fifth Avenue, 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. 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 September 30, 2022, the Adviser, together with its affiliated asset management companies, had approximately $1.3 trillion in assets under management or supervision.

A discussion regarding the Board of Trustees’ approval of the Management Agreement will be available in the Fund’s semi-annual report to shareholders for the period ending March 31, 2023.

Management Fees

The Adviser receives a fee for management services equal to 0.29% of the Fund’s average daily net assets.

Under the Management Agreement, the Adviser will pay substantially all the expenses of the Fund (including expenses of the Trust relating to the Fund), except for the distribution fees, if any, brokerage expenses, acquired fund fees and expenses, taxes, interest, litigation expenses, and other extraordinary expenses, including the costs of proxies, not incurred in the ordinary course of the Fund’s business.

Portfolio Management

The Fund is managed by Jade Huang, Christopher Madden, James Reber, Thomas C. Seto, and Matthew Maillet, who are jointly and primarily responsible for the day-to-day management of the Funds. Ms. Huang and Messrs. Madden, Seto and Reber are Managing Directors of the Adviser and have been associated with the Morgan Stanley organization for more than five years. Mr. Maillet has been an Executive Director of the Adviser since 2022 and was associated with Goldman Sachs Asset Management, L.P. from 2014 until he joined Morgan Stanley.

The Fund’s SAI provides additional information about the portfolio managers’ compensation structure, other accounts managed by the portfolio managers and the portfolio managers’ ownership of securities in the Fund.

Distribution of Fund Shares

The Distributor is the exclusive distributor of Creation Units of the Fund. The Distributor or its agent distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the investment policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is 3 Canal Plaza Suite 100, Portland, ME 04101.

The Board of Trustees of the Trust has adopted a distribution and service plan (“Plan”) pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, the Fund is authorized to pay distribution fees in connection with the sale and distribution of its shares and pay service fees in connection with the provision of ongoing services to shareholders of the Fund and the maintenance of shareholder accounts in an amount up to 0.25% of its average daily net assets each year.

No Rule 12b-1 fees are currently paid by the Fund, and there are no current plans to impose these fees. However, in the event Rule 12b-1 fees are charged in the future, because these fees are paid out of the Fund’s assets on an ongoing basis, these fees will increase the cost of your investment in the Fund. By purchasing shares subject to distribution fees and service fees, you may pay more over time than you would by purchasing shares with other types of sales charge arrangements. Long-term shareholders may pay more than the economic equivalent of the maximum front-end sales charge permitted by the rules of FINRA. The net income attributable to shares will be reduced by the amount of distribution fees and service fees and other expenses of the Fund.

About Net Asset Value

The Fund’s NAV per share is determined by dividing the total of the value of the Fund’s investments and other assets, less any liabilities attributable to the Fund, by the total number of outstanding shares of the Fund. In making this calculation, the 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 Board of Trustees. The Adviser, consistent with its procedures and applicable regulatory guidance, may (but need not) determine to make an adjustment to the previous closing prices of either domestic or foreign securities in light of significant events, to reflect what it believes to be the fair value of the securities at the time of determining the Fund’s NAV. In these cases, the Fund’s NAV will reflect certain portfolio securities’ fair value rather than their market price. To the extent the Fund invests in open-end management companies (other than ETFs) that are registered under 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 the Fund’s portfolio securities may change on days when you will not be able to purchase or sell your shares. The NAV of the Fund is based on the value of the Fund’s portfolio securities or other assets.

The Fund relies on various sources to calculate its NAV. The ability of the 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. The 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 the 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.

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

Book Entry

The Depository Trust Company (“DTC”) serves as securities depository for the shares. (The shares may be held only in book-entry form; stock certificates will not be issued.) DTC, or its nominee, is the record or registered owner of all outstanding shares. Beneficial ownership of shares will be shown on the records of DTC or its participants (described below). Beneficial owners of shares are not entitled to have shares registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and are not considered the registered holder thereof. Accordingly, to exercise any rights of a holder of shares, each beneficial owner must rely on the procedures of: (i) DTC; (ii) “DTC Participants,” i.e., securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC; and (iii) “Indirect Participants,” i.e., brokers, dealers, banks and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly, through which such beneficial owner holds its interests. The Trust understands that under

existing industry practice, in the event the Trust requests any action of holders of shares, or a beneficial owner desires to take any action that DTC, as the record owner of all outstanding shares, is entitled to take, DTC would authorize the DTC Participants to take such action and that the DTC Participants would authorize the Indirect Participants and beneficial owners acting through such DTC Participants to take such action and would otherwise act upon the instructions of beneficial owners owning through them. As described above, the Trust recognizes DTC or its nominee as the owner of all shares for all purposes.

Buying and Selling Shares

Shares of the Fund may be acquired or redeemed directly from the Fund at NAV only in Creation Units or multiples thereof, as discussed in the “Creations and Redemptions” section of the Prospectus. Only an Authorized Participant (as defined in the “Creations and Redemptions” section below) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed for trading on a national securities exchange during the trading day. Shares can be bought and sold throughout the trading day at market price like shares of other publicly traded companies. However, there can be no guarantee that an active trading market will develop or be maintained, or that the Fund shares listing will continue or remain unchanged. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. Buying or selling the Fund’s shares involves certain costs that apply to all securities transactions. When buying or selling shares of the Fund through a financial intermediary, you may incur a brokerage commission or other charges determined by your financial intermediary. Due to these brokerage costs, if any, frequent trading may detract significantly from investment returns. In addition, you may also incur the cost of the spread (the difference between the bid price and the ask price). The commission is frequently a fixed amount and may be a significant cost for investors seeking to buy or sell small amounts of shares. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally less if the Fund has more trading volume and market liquidity and more if the Fund has less trading volume and market liquidity.

The Fund’s primary listing exchange is NYSE Arca. NYSE Arca is open for trading Monday through Friday and is closed on the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

A “business day” with respect to the Fund is each day the New York Stock Exchange, NYSE Arca, and the Trust are open and includes any day that the Fund is required to be open under Section 22(e) of the 1940 Act. Orders from authorized participants to create or redeem Creation Units will only be accepted on a business day. On days when NYSE Arca closes earlier than normal, the Fund may require orders to create or redeem Creation Units to be placed earlier in the day. See the SAI for more information.

The Trust’s Board of Trustees has not adopted a policy of monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of potential arbitrage opportunities presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”). The Trust believes this is appropriate because ETFs, such as the Fund, are intended to be attractive to arbitrageurs, as trading activity is critical to ensuring that the market price of Fund shares remains at or close to NAV. Since the Fund issues and redeems Creation Units at NAV plus applicable transaction fees, and the Fund’s shares may be purchased and sold on NYSE Arca at prevailing market prices, the risks of frequent trading are limited.

Section 12(d)(1) of the 1940 Act generally restricts investments by investment companies, including foreign and unregistered investment companies, in the securities of other investment companies. For example, a registered investment company (the “Acquired Fund”), such as the Fund, may not knowingly sell or otherwise dispose of any security issued by the Acquired Fund to any investment company (the “Acquiring Fund”) or any company or companies controlled by the Acquiring Fund if, immediately after such sale or disposition: (i) more than 3% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and any company or companies controlled by the Acquiring Fund, or (ii) more than 10% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and other investment companies and companies controlled by them. However, registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) in reliance on Rule 12d1-4 under the 1940 Act, the registered investment company must, among other things, enter into an agreement with the Trust. Foreign investment companies are permitted to invest in the Fund only up to the limits set forth in Section 12(d)(1), subject to any applicable SEC Staff no-action relief.

The Fund and the Distributor will have the sole right to accept orders to purchase shares and reserve the right to reject any purchase order in whole or in part.

Creations and Redemptions

Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) enters into an authorized participant agreement with the Fund’s Distributor. An Authorized Participant is a member or participant of a

clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units.

A creation transaction, which is subject to acceptance by JPMorgan Chase Bank N.A., as the Trust’s transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash in exchange for a specified number of Creation Units.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by the Fund and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.

Only an Authorized Participant may create or redeem Creation Units directly with the Fund.

In the event of a system failure or other interruption, including disruptions at market makers or authorized participants, orders to purchase or redeem Creation Units either may not be executed according to the Fund’s instructions or may not be executed at all, or the Fund may not be able to place or change orders.

To the extent the Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the Securities Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC Participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) and the applicable transaction fees is included in the Fund’s SAI.

Portfolio Holdings

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

Dividends and Distributions

General Policies

Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income or realized gains. Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service

No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes

As with any investment, you should consider how your Fund investment will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in the Fund. Unless your investment in the Fund is through a tax deferred retirement account, such as a 401(k) plan or IRA, you need to be

aware of the possible tax consequences when the Fund makes distributions and when you sell shares, including an exchange to another Morgan Stanley Fund.

Taxation of Distributions. Your distributions normally are subject to federal and state income tax when they are paid, whether you take them in cash or reinvest them in Fund shares. A distribution also may be subject to local income tax. Any income dividend distributions and any short-term capital gain distributions are taxable to you as ordinary income. Any long-term capital gain distributions are taxable as long-term capital gains, no matter how long you have owned shares in the Fund.

If certain holding period requirements are met with respect to your shares, a portion of the income dividends you receive may be taxed at the same rates as long-term capital gains. However, even if income received in the form of income dividends is taxed at the same rates as long-term capital gains, such income will not be considered long-term capital gains for other federal income tax purposes. For example, you will not be permitted to offset income dividends with capital losses. Short term capital gain distributions will continue to be taxed as ordinary income taxes.

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 such portfolios from U.S. corporations.

If you buy shares of the Fund before a distribution, you may 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 the Fund before your investment (and thus were included in the price you paid for your Fund shares).

Investment income received by the Fund from sources within foreign countries may be subject to foreign income, withholding, and other taxes. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes.

You will be sent a statement (Internal Revenue Service (“IRS”) Form 1099-DIV) by February of each year showing the taxable distributions paid to you in the previous year. The statement provides information on your dividends and any capital gains for tax purposes.

Taxation of Sales. Your sale of Fund shares normally is subject to federal and state income tax and may result in a taxable gain or loss to you. A sale also may be subject to local income tax. Your exchange of Fund shares for shares of another Morgan Stanley Fund is treated for tax purposes like a sale of your original shares and a purchase of your new shares. Thus, the exchange may, like a sale, result in a taxable gain or loss to you and will give you a new tax basis for your shares. When you sell your shares, you will generally recognize a capital gain or loss in an amount equal to the difference between your adjusted tax basis in the shares and the amount received. Generally, this capital gain or loss is long-term or short-term depending on whether your holding period exceeds one year, except that any loss realized on shares held for six months or less will be treated as a long-term capital loss to the extent of any long-term capital gain dividends that were received on the shares. Additionally, any loss realized on a sale, exchange or redemption of Shares of the Fund may be disallowed under “wash sale” rules to the extent the shares disposed of are replaced with other shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition, such as pursuant to a dividend reinvestment in Fund shares. If disallowed, the loss will be reflected in an adjustment to the basis of the shares acquired.

Creations and Redemptions. A person who exchanges securities for Creation Units generally will recognize a gain or loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time of exchange and the sum of the exchanger’s aggregate basis in the securities surrendered and the amount of any cash paid for such Creation Units. A person who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the sum of the aggregate market value of the securities received. The IRS, however, may assert that a loss realized upon an exchange of primarily securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons exchanging securities for Creation Units or redeeming Creation Units should consult their own tax adviser with respect to whether wash sale rules apply and when a loss might be deductible and the tax treatment of any creation or redemption transaction.

Under current U.S. federal income tax laws, any capital gain or loss realized upon a redemption (or creation) of Creation Units is generally treated as long-term capital gain or loss if the Fund shares (or securities surrendered) have been held for more than one year and as a short-term capital gain or loss if the Fund shares (or securities surrendered) have been held for one year or less.

Other Information. An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from the 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.

You may be subject to backup withholding at a rate of 24% with respect to taxable distributions if you do not provide your correct taxpayer identification number, or certify that it is correct, or if you have been notified by the IRS that you are subject to backup

withholding. 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 the Fund of investment income and short-term capital gains.

Withholding of U.S. tax is required (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 Fund to enable the Fund to determine whether withholding is required.

Reporting to you and the IRS is required annually on Form 1099-B not only the gross proceeds of Fund shares you sell or redeem but also their cost basis. Shareholders should contact their intermediaries with respect to reporting of cost basis and available elections with respect to their accounts. You should carefully review the cost basis information provided by the applicable intermediary and make any additional basis, holding period or other adjustments that are required when reporting these amounts on your federal income tax returns.

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

Tax-Advantaged Product Structure

Unlike interests in many conventional mutual funds, the shares are traded throughout the day on a national securities exchange, whereas mutual fund interests are typically only bought and sold at closing NAVs. The shares have been designed to be tradable in the secondary market on a national securities exchange on an intra-day basis, and to be created and redeemed in Creation Units at each day’s next calculated NAV. Shares are created and redeemed principally in kind. The in-kind arrangements are designed to protect ongoing shareholders from adverse effects on the Fund’s portfolio that could arise from frequent cash creation and redemption transactions. In a conventional mutual fund, redemptions can have an adverse tax impact on taxable shareholders because the mutual fund may need to sell portfolio securities to obtain cash to meet fund redemptions. These sales may generate taxable gains for the shareholders of the mutual fund, whereas the shares‘ in-kind redemption mechanism generally will not lead toa tax event for the Fund or its ongoing shareholders.

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 the 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 the 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 the 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 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 Fund (including purchasing or selling securities that the Adviser may otherwise have purchased or sold for the 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 the Fund or its shareholders. The 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 the 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 Fund, 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 the 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 the 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 the 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 the 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 the 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 the 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 the Fund and with respect to investments that the 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 the Fund. Morgan Stanley may give advice and provide recommendations to persons competing with the Fund and/or any of the Fund’s investments that are contrary to the Fund’s best interests and/or the best interests of any of its investments. Morgan Stanley’s activities on behalf of its clients (such as engagements as an underwriter or placement agent) may restrict or otherwise limit investment opportunities that may otherwise be available to the Fund.

Morgan Stanley may be engaged to act as a financial advisor to a company in connection with the sale of such company, or subsidiaries or divisions thereof, may represent potential buyers of businesses through its mergers and acquisition activities and may provide lending and other related financing services in connection with such transactions. Morgan Stanley’s compensation for such activities is usually based upon realized consideration and is usually contingent, in substantial part, upon the closing of the transaction. Under these circumstances, the Fund may be precluded from participating in a transaction with or relating to the company being sold or participating in any financing activity related to a merger or an acquisition.

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Trust on an ongoing basis, a “distribution,” as such term is used in the Securities Act may occur at any point. Broker dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the Securities Act.

For example, a broker dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares, and sells such shares directly to customers, or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary trading transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the Securities Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. This is because the prospectus delivery exemption in Section 4(a)(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker dealer firms should note that dealers who are not underwriters but are participating in a distribution (as contrasted with ordinary secondary market transactions) and thus dealing with the shares that are part of an overallotment within the meaning of Section 4(a)(3)(A) of the Securities Act would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. Firms that incur a prospectus delivery obligation with respect to shares are reminded that, under Rule 153 of the Securities Act, a prospectus delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on the Exchange is satisfied by the fact that the prospectus is available at the Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange.

In addition, certain affiliates of the Fund and the Adviser may purchase and resell Fund shares pursuant to this Prospectus.
