Investment Objective

Calvert Ultra-Short Investment Grade ETF (the “Fund”) seeks to maximize income, to the extent consistent with preservation of capital, through investment in short-term bonds and income-producing securities.

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	0.24%
Other Expenses²	0.00%
Total Annual Fund Operating Expenses	0.24%

[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
	$25	$77

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

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets (including any borrowings for investment purposes) in a portfolio of investment grade, short-term fixed, variable and floating-rate securities. 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 not a money market fund and does not seek to maintain a stable net asset value.

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

Under normal circumstances, the Fund’s average portfolio duration will be one year or less. In certain market conditions, such as in periods of significant volatility in interest rates and spreads, the Fund’s duration may be longer than one year. During periods when the Fund’s average duration is longer than one year, the Fund may not achieve its investment objective.

The Fund will only invest in investment grade securities, as assessed at the time of purchase. The Fund invests principally in U.S. dollar-denominated debt securities. A debt security is considered investment grade when assigned a credit quality rating of BBB- or higher by S&P Global Ratings (“S&P”) or an equivalent rating by another nationally recognized statistical rating organization (‘‘NRSRO”), including Moody’s Investors Service or Fitch Ratings, or Kroll Bond Rating Agency, LLC for securitized debt instruments only (such as asset-backed securities (“ABS”) and mortgage-backed securities (“MBS”)) or if unrated, considered to be of comparable credit quality by the Adviser. For purposes of rating restrictions, if securities are rated differently by two or more rating agencies, the highest rating is used.

The Fund invests principally in bonds issued by U.S. corporations, the U.S. Government or its agencies, and U.S. government-sponsored enterprises (“GSEs”) such as the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”). The Fund also may invest in trust preferred securities, money market instruments and taxable municipal obligations.

The Fund may invest up to 50% of its net assets in ABS and MBS that represent interests in pools of mortgage loans (MBS) or other assets (ABS) assembled for sale to investors by various U.S. governmental agencies, government-related organizations and private issuers. MBS may include collateralized mortgage obligations (“CMOs”) and commercial mortgage-backed securities (“CMBS”). The Fund may invest up to 25% of its net assets in non-agency ABS and MBS.

The Fund may also invest up to 25% of its net assets in foreign debt securities. Foreign debt securities include American Depositary Receipts (“ADRs”). The Fund may engage in forward foreign currency exchange contracts to seek to hedge against the decline in the value of currencies in which its portfolio holdings are denominated against the U.S. dollar. The Fund may also lend its securities.

The Fund will concentrate its investments in the banking industry. Therefore, under normal conditions, the Fund will invest more than 25% of its total assets in securities issued by issuers in the banking industry.

The portfolio managers are responsible for fundamental analysis and security selection, incorporating environmental, social and governance (“ESG”) information provided by ESG analysts at Calvert Research and Management (“Calvert”). The Fund seeks to invest in issuers that manage ESG risk exposures adequately and that are not exposed to excessive ESG risk through their principal business activities. Issuers are analyzed by Calvert’s ESG analysts utilizing the Calvert Principles for Responsible Investment, a framework for considering ESG factors (a copy of which is included as an appendix to the Fund’s Prospectus). Management of the Fund involves consideration of numerous factors other than ESG, such as quality of business franchises, financial strength, management quality and security structural and collateral considerations. The portfolio managers may also use sector rotation and relative value strategies in their management of the Fund. The portfolio managers may sell a security when the Adviser’s valuation target is reached, the fundamentals of the investment change or to pursue more attractive investment options. A security will also be sold (in accordance with the Adviser’s guidelines and at a time and in a manner that is determined to be in the best interests of shareholders) if the Adviser determines that the issuer does not operate in a manner consistent with the Fund’s responsible investment criteria. The portfolio managers intend to focus on risk management and also seek to preserve capital to the extent consistent with the Fund’s investment objective. The Fund intends to seek to manage investment risk by maintaining broad issuer and industry diversification among its holdings, and by utilizing fundamental analysis of risk/return characteristics in securities selection. The Fund seeks to manage duration and any hedging of interest rate risk through the purchase and sale of U.S. Treasury securities and related futures contracts (which are a type of derivative instrument).

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 accordance 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:

•

Fixed-Income Securities. Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity (i.e., interest rate risk), market perception of the creditworthiness of the issuer and general market liquidity (i.e., market risk). The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk). The Fund may invest in securities of any maturity (when a debt security provides its final payment) or duration (measure of interest rate sensitivity). Securities with longer durations are likely to be more sensitive to changes in interest rates, generally making them more volatile than securities with shorter durations. Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. A portion of the Fund’s fixed-income securities may be rated below investment grade. The Fund may be subject to

certain liquidity risks that may result from the lack of an active market and the reduced number and capacity of traditional market participants to make a market in fixed-income securities.

•

Credit and Interest Rate Risk. Credit risk refers to the possibility that the issuer or guarantor of a security will be unable or unwilling or perceived to be unable to unwilling to make interest payments and/or repay the principal on its debt. In such instances, the value of the Fund could decline and the Fund could lose money. Interest rate risk refers to the decline in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. The Fund may invest in variable and floating rate loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk). During periods when interest rates are low or there are negative interest rates, the Fund’s yield (and total return) also may be low or otherwise adversely affected or the Fund may be unable to maintain positive returns. Credit ratings may not be an accurate assessment of liquidity or credit risk. Although credit quality may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer can have a rapid, adverse effect on the instrument’s liquidity and make it more difficult for the Fund to sell at an advantageous price or time.

•

LIBOR Discontinuance or Unavailability Risk. The London InterBank Offered Rate (“LIBOR”) is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. The regulatory authority that oversees financial services firms and financial markets in the U.K. has announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions for purposes of determining the LIBOR rate. However, subsequent announcements by the Financial Conduct Authority, the LIBOR administrator and other regulators indicate that it is possible that the most widely used tenors of U.S. Dollar LIBOR may continue to be provided on a representative basis until mid-2023. However, in connection with supervisory guidance from regulators, some regulated entities ceased to enter into most new LIBOR-based contracts after January 1, 2022. As a result, it is possible that LIBOR may no longer be available or no longer deemed an appropriate reference rate upon which to determine the interest rate on or impacting certain loans, notes, derivatives and other instruments or investments comprising some or all of the Fund’s portfolio.

•

Asset-Backed Securities. Asset-backed securities involve the risk that various federal and state consumer laws and other legal and economic factors may result in the collateral backing the securities being insufficient to support payment on the securities. To the extent the Fund invests in asset-backed securities issued by non-governmental issuers, such as commercial banks, savings and loan institutions, and other secondary market issuers, the Fund will be exposed to additional risks because, among other things, there are no direct or indirect government or agency guarantees of payments in the pools underlying the securities. Some asset-backed securities also entail prepayment risk and extension risk, which may vary depending on the type of asset.

•

Mortgage-Backed Securities. Mortgage-backed securities entail prepayment risk, which generally increases during a period of falling interest rates. Rising interest rates tend to discourage refinancings, with the result that the average life and volatility of mortgage-backed securities will increase and market price will decrease. Rates of prepayment, faster or slower than expected by the Adviser, could reduce the Fund’s yield, increase the volatility of the Fund and/or cause a decline in net asset value (“NAV”). Mortgage-backed securities are also subject to extension risk, which is the risk that rising interest rates could cause mortgages or other obligations underlying the securities to be prepaid more slowly than expected, thereby lengthening the duration of such securities, increasing their sensitivity to interest rate changes and causing their prices to decline. Certain mortgage-backed securities may be more volatile and less liquid than other traditional types of debt securities. In addition, mortgage-backed securities are subject to credit risk. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of a mortgage-backed security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Furthermore, mortgage-backed securities may be subject to risks associated with the assets underlying those securities, such as a decline in value. Investments in mortgage-backed securities may give rise to a form of leverage (indebtedness) and may cause the Fund’s portfolio turnover rate to appear higher. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. The risks associated with mortgage-backed securities typically become elevated during periods of distressed economic, market, health and labor conditions. In particular, increased levels of unemployment, delays and delinquencies in payments of mortgage and rent obligations, and uncertainty regarding the effects and extent of government intervention with respect to mortgage payments and other economic matters may adversely affect the Fund’s investments in mortgage-backed securities. To the extent the Fund invests in mortgage-backed securities issued by non-governmental issuers, such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers, the Fund will be exposed to additional risks because, among other things, there are no direct or indirect government or agency guarantees of payments in pools underlying the securities.

•

U.S. Government Securities. Different types of U.S. government securities are subject to different levels of credit risk, including the risk of default, depending on the nature of the particular government support for that security. For example, a U.S. government-sponsored entity, such as FNMA or FHLMC, although chartered or sponsored by an Act of Congress, may issue securities that are neither insured nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. With respect to U.S. government securities that are not backed by the full faith and credit of the United States, there is the risk that the U.S. Government will not provide financial support to such U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.

•

Money Market Instrument Risk. Money market instruments may be adversely affected by market and economic events, such as a sharp rise in prevailing short-term interest rates; adverse developments in the banking industry, which issues or guarantees many money market instruments; adverse economic, political or other developments affecting issuers of money market instruments; changes in the credit quality of issuers; and default by a counterparty.

•

Preferred Securities. Preferred stock is issued with a fixed par value and pays dividends based on a percentage of that par value at a fixed rate. As with fixed-income securities, which also make fixed payments, the market value of preferred stock is sensitive to changes in interest rates. Preferred stock generally decreases in value if interest rates rise and increases in value if interest rates fall.

•

Municipals. Because the Fund may invest in municipal securities (also referred to as municipal obligations), the Fund may be susceptible to political, legislative, economic, regulatory, tax or other factors affecting issuers of these municipal securities, such as state and local governments and their agencies. To the extent that the Fund invests in municipal securities of issuers in the same economic sector, it could be more sensitive to economic, business or political developments that affect such sector. Municipal securities and their issuers may be more susceptible to downgrade, loss of revenue, default and bankruptcy because of recent periods of economic stress. Municipal securities also involve the risk that an issuer may call the securities for redemption, which could force the Fund to reinvest the proceeds at a lower rate of interest. While interest earned on municipal securities is generally not subject to federal income tax, any interest earned on taxable municipal securities is fully taxable at the federal level and may be subject to state and/or local income tax.

•

Foreign Securities. Investments in foreign markets entail special risks such as currency, political, economic and market risks. There also may be greater market volatility, less reliable financial information, less stringent investor protections and disclosure standards, higher transaction and custody costs, decreased market liquidity and less government and exchange regulation associated with investments in foreign markets. In addition, investments in certain foreign markets that have historically been considered stable may become more volatile and subject to increased risk due to ongoing developments and changing conditions in such markets. Moreover, the growing interconnectivity of global economies and financial markets has increased the probability that adverse developments and conditions in one country or region will affect the stability of economies and financial markets in other countries or regions. Certain foreign markets may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments, the imposition of economic sanctions against a particular country or countries, organizations, companies, entities and/or individuals, changes in international trading patterns, trade barriers and other protectionist or retaliatory measures. Investments in foreign markets may also be adversely affected by governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. The governments of certain countries may prohibit or impose substantial restrictions on foreign investing in their capital markets or in certain sectors or industries. In addition, a foreign government may limit or cause delay in the convertibility or repatriation of its currency which would adversely affect the U.S. dollar value and/or liquidity of investments denominated in that currency. Certain foreign investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, its portfolio may be harder to value. In addition, the Fund’s investments in foreign issuers may be denominated in foreign currencies and therefore, to the extent unhedged, the value of those investments will fluctuate with U.S. dollar exchange rates. To the extent hedged by the use of foreign currency forward exchange contracts, the precise matching of the foreign currency forward exchange contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. There is additional risk that such transactions may reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken and that foreign currency forward exchange contracts create exposure to currencies in which the Fund’s securities are not denominated. The use of foreign currency forward exchange contracts involves the risk of loss from the insolvency or bankruptcy of the counterparty to the contract or the failure of the counterparty to make payments or otherwise comply with the terms of the contract.

•

Foreign Currency. The Fund’s investments in foreign securities may be denominated in foreign currencies. The value of foreign currencies may fluctuate relative to the value of the U.S. dollar. Since the Fund may invest in such non-U.S. dollar-denominated securities, and therefore may convert the value of such securities into U.S. dollars, changes in currency exchange rates can increase or decrease the U.S. dollar value of the Fund’s assets. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the overall economic health of the issuer. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments

denominated in that currency. The Adviser may use derivatives to reduce this risk. The Adviser may in its discretion choose not to hedge against currency risk. In addition, certain market conditions may make it impossible or uneconomical to hedge against currency risk.

•

Restricted Securities. The Fund’s investments may include securities which are subject to resale restrictions. These securities could have the effect of increasing the level of Fund illiquidity to the extent the Fund may be unable to sell or transfer these securities due to restrictions on transfers or on the ability to find buyers interested in purchasing the securities. Additionally, the market for certain investments deemed liquid at the time of purchase may become illiquid under adverse market or economic conditions. The illiquidity of the market, as well as the lack of publicly available information regarding these securities, may also adversely affect the ability to arrive at a fair value for certain securities at certain times and could make it difficult for the Fund to sell certain securities. If the Fund is forced to sell an illiquid security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.

•

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 fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.

•

Derivatives. 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.

•

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.

•	Securities Lending. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral if the borrower fails financially. The Fund could also lose money if the value of the collateral decreases.

•

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.

•

Cash Transactions Risk. Unlike certain ETFs, the Fund may effect creations and redemptions in cash or partially in cash. Therefore, it may be required to sell portfolio securities and subsequently recognize gains on such sales that the Fund might not have recognized if it were to distribute portfolio securities in-kind. As such, investments in shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind.

•

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.

•	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.

•

Banking Industry. Investment opportunities in investment grade securities may be concentrated in the banking industry. Under normal conditions, the Fund will invest more than 25% of its total assets in securities issued by issuers in the banking industry. As a result, the Fund may have a high concentration of investments in the banking industry. The banking industry can be affected by global and local economic conditions, such as the levels and liquidity of the global and local financial and asset markets, the absolute and relative level and volatility of interest rates and equity prices, investor sentiment, inflation, and the availability and cost of credit. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operations and profitability of the banking industry. Because the Fund’s investments will be concentrated in the banking industry, factors that have an adverse impact on this industry may have a disproportionate impact on 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.

Investment Objective

The Fund’s investment objective is to seek to maximize income, to the extent consistent with preservation of capital, through investment in short-term bonds and income-producing securities.

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 investing, under normal circumstances, at least 80% of its net assets (including any borrowings for investment purposes) in a portfolio of investment grade, short-term fixed, variable and floating-rate securities. This policy may be changed without shareholder approval; however, shareholders would be notified upon 60 days’ notice in writing of any changes. 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. The Fund is not a money market fund and does not seek to maintain a stable net asset value.

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

Process

The Fund will only invest in investment grade securities as assessed at the time of purchase. The Fund invests principally in U.S. dollar-denominated debt securities. A debt security is considered investment grade when assigned a credit quality rating of BBB- or higher by S&P or an equivalent rating by another NRSRO, including Moody’s Investors Service or Fitch Ratings, or Kroll Bond Rating Agency, LLC for securitized debt instruments only (such as ABS and MBS) or if unrated, considered to be of comparable credit quality by the Adviser. For purposes of rating restrictions, if securities are rated differently by two or more rating agencies, the highest rating is used.

The Fund invests principally in bonds issued by U.S. corporations, the U.S. Government or its agencies, and GSEs such as the FNMA and FHLMC. The Fund also may invest in trust preferred securities, money market instruments and taxable municipal obligations.

The Fund may invest up to 50% of its net assets in ABS and MBS that represent interests in pools of mortgage loans (MBS) or other assets (ABS) assembled for sale to investors by various U.S. governmental agencies, government-related organizations and private issuers. MBS may include CMOs and CMBS. The Fund may invest up to 25% of its net assets in non-agency ABS and MBS.

The Fund may also invest up to 25% of its net assets in foreign debt securities. Foreign debt securities include ADRs. The Fund may engage in forward foreign currency exchange contracts to seek to hedge against the decline in the value of currencies in which its portfolio holdings are denominated against the U.S. dollar. The Fund may also lend its securities.

The portfolio managers are responsible for fundamental analysis and security selection, incorporating ESG information provided by ESG analysts at Calvert. The Fund seeks to invest in issuers that manage ESG risk exposures adequately and that are not exposed to excessive ESG risk through their principal business activities. Issuers are analyzed by Calvert’s ESG analysts utilizing The Calvert Principles for Responsible Investment, a framework for considering ESG factors (a copy of which is included as an appendix to the Fund’s Prospectus). Management of the Fund involves consideration of numerous factors other than ESG, such as quality of business franchises, financial strength, management quality and security structural and collateral considerations. The portfolio managers may also use sector rotation and relative value strategies in their management of the Fund. The portfolio managers may sell a security when the Adviser’s valuation target is reached, the fundamentals of the investment change or to pursue more attractive investment options. A security will also be sold (in accordance with the Adviser’s guidelines and at a time and in a manner that is determined to be in the best interests of shareholders) if the Adviser determines that the issuer does not operate in a manner consistent with the Fund’s responsible investment criteria. The portfolio managers intend to focus on risk management and also seek to preserve capital to the extent consistent with the Fund’s investment objective. The Fund intends to seek to manage investment risk by maintaining broad issuer and industry diversification among its holdings, and by utilizing fundamental analysis of risk/return characteristics in securities selection. The Fund seeks to manage duration and any hedging of interest rate risk through the purchase and sale of U.S. Treasury securities and related futures contracts (which are a type of derivative instrument).


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 Fund is not a money market fund (or equivalent to a money market fund), does not attempt to maintain a stable net asset value, and is not subject to the rules that govern the quality, maturity, liquidity, and other features of securities that money market funds may purchase. Under normal conditions, the Fund’s investments may be more susceptible than a money market fund to interest rate risk, valuation risk, credit risk, and other risks relevant to the Fund’s investments.

Fixed-Income Securities

Fixed-income securities are securities that pay a fixed or a variable rate of interest until a stated maturity date. Fixed-income securities include U.S. government securities, securities issued by federal or federally sponsored agencies and instrumentalities, corporate bonds and notes, asset-backed securities, mortgage securities, securities rated below investment grade (commonly referred to as “junk bonds” or “high yield/high risk securities”), municipal bonds, loan participations and assignments, zero coupon bonds, Eurobonds, Brady Bonds, Yankee Bonds, repurchase agreements, commercial paper and cash equivalents.

Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity (i.e., interest rate risk), market perception of the creditworthiness of the issuer and general market liquidity (i.e., market risk). The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk). Securities with longer durations are likely to be more sensitive to changes in interest rates, generally making them more volatile than securities with shorter durations. Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. Fixed-income securities may be called (i.e., redeemed by the issuer) prior to final maturity. If a callable security is called, the Fund may have to reinvest the proceeds at a lower rate of interest.

Duration

The average duration of a portfolio of fixed-income securities represents its exposure to changing interest rates. For example, when the level of interest rates increases by 1%, a fixed-income security having a positive duration of four years generally will decrease in value by 4%; when the level of interest rates decreases by 1%, the value of that same security generally will increase by 4%. A portfolio with a lower average duration generally will experience less price volatility in response to changes in interest rates than a portfolio with a higher average duration.

Credit and Interest Rate Risk

Fixed-income securities, such as bonds, generally are subject to two types of risk: credit risk and interest rate risk. Credit risk refers to the possibility that the issuer or guarantor of a security will be unable or unwilling or perceived to be unable or unwilling to make interest payments and/or repay the principal on its debt. The risk of defaults across issuers and/or counterparties increases in adverse market and economic conditions. Interest rate risk refers to fluctuations (such as a decline) in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. During periods when interest rates are low or there are negative interest rates, the Fund’s yield (and total return) also may be low or otherwise adversely affected or the Fund may be unable to maintain positive returns. Credit ratings may not be an accurate assessment of liquidity or credit risk. Although credit quality may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer can have a rapid, adverse effect on the instrument’s liquidity and make it more difficult for the Fund to sell at an advantageous price or time.

In addition, under certain conditions, there may be an increasing amount of issuers that are unprofitable, have little cash on hand and/or are unable to pay the interest owed on their debt obligations and the number of such issuers may increase if demand for their goods and services falls, borrowing costs rise due to governmental action or inaction or other reasons.

LIBOR

LIBOR is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. The regulatory authority that oversees financial services firms and financial markets in the U.K. has announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions for purposes of determining the LIBOR rate. However, subsequent announcements by the Financial Conduct Authority, the LIBOR administrator and other regulators indicate that it is possible that the most widely used tenors of U.S. Dollar LIBOR may continue to be provided on a representative basis until mid-2023. However, in connection with supervisory guidance from regulators, some regulated entities ceased to enter into most new LIBOR-based contracts after January 1, 2022. As a result, it is possible that LIBOR may no longer be available or no longer deemed an appropriate reference rate upon which to determine the interest rate on or impacting certain derivatives and other instruments or investments comprising some or all of the Fund’s portfolio. In light of this eventuality, public and private sector industry initiatives are currently underway to establish new or alternative reference rates to be used in place of LIBOR. There is no assurance that the composition or characteristics of any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that it will have the same volume or liquidity as did LIBOR prior to its discontinuance or unavailability, which may affect the value or liquidity or return on certain of the Fund’s investments and result in costs incurred in connection with closing out positions and entering into new trades.

Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of new hedges placed against, instruments whose terms currently include LIBOR. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. In addition, a liquid market for newly-issued instruments that use a reference rate other than LIBOR still may be developing. There may also be challenges for the Fund to enter into hedging transactions against such newly-issued instruments until a market for such hedging transactions develops. All of the aforementioned may adversely affect the Fund’s performance or net asset value.

Asset-Backed Securities

Asset-backed securities apply the securitization techniques used to develop mortgage-backed securities to a broad range of other assets. Various types of assets, primarily automobile and credit card receivables and home equity loans, are pooled and securitized in pass-through structures similar to pass-through structures developed with respect to mortgage securitizations. Asset-backed securities have risk characteristics similar to mortgage-backed securities. Like mortgage-backed securities, they generally decrease in value as a result of interest rate increases, but may benefit less than other fixed-income securities from declining interest rates, principally because of prepayments. Also, as in the case of mortgage-backed securities, prepayments generally increase during a period of declining interest rates, although other factors, such as changes in credit use and payment patterns, may also influence prepayment rates. Asset-backed securities also involve the risk that various federal and state consumer laws and other legal and economic factors may result in the collateral backing the securities being insufficient to support payment on the securities.

To the extent the Fund invests in asset-backed securities issued by non-governmental issuers, such as commercial banks, savings and loan institutions, and other secondary market issuers, the Fund will be exposed to additional risks because, among other things, there are no direct or indirect government or agency guarantees of payments in the pools underlying the securities. Privately-issued asset-backed securities may be less readily marketable and the market for such securities is typically smaller and less liquid than other asset-backed securities.

Mortgage-Backed Securities

Mortgage securities are fixed-income securities representing an interest in a pool of underlying mortgage loans. They are sensitive to changes in interest rates, but may respond to these changes differently from other fixed-income securities due to the possibility of prepayment of the underlying mortgage loans. As a result, it may not be possible to determine in advance the actual maturity date or average life of a mortgage security. Rising interest rates tend to discourage refinancings, with the result that the average life and volatility of the security will increase and its market price will decrease. When interest rates fall, however, mortgage securities may not gain as much in market value because additional mortgage prepayments must be reinvested at lower interest rates. Prepayment risk may make it difficult to calculate the average maturity of a portfolio of mortgage securities and, therefore, to assess the volatility risk of that portfolio.

The Fund may invest in mortgage securities that are issued or guaranteed by the U.S. Government, its agencies or instrumentalities. These securities are either direct obligations of the U.S. Government or the issuing agency or instrumentality has the right to borrow from the U.S. Treasury to meet its obligations although it is not legally required to extend credit to the agency or instrumentality.

Certain of these mortgage securities purchased by the Fund, such as those issued by the Government National Mortgage Association and the Federal Housing Administration, are backed by the full faith and credit of the United States. Other of these mortgage securities purchased by the Fund, such as those issued by FNMA and FHLMC, are not backed by the full faith and credit of the United States and there is a risk that the U.S. Government will not provide financial support to these agencies if it is not obligated to do so by law. The maximum potential liability of the issuers of some of the mortgage securities held by the Fund may greatly exceed their current resources, including their legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.

To the extent the Fund invests in mortgage-backed securities issued by non-governmental issuers, such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers, the Fund will be exposed to additional risks because, among other things, there are no direct or indirect government or agency guarantees of payments in the pools underlying the securities. However, timely payment of interest and principal of these pools may be supported by various forms of private insurance or guarantees, including individual loan, title, pool and hazard insurance and letters of intent. The insurance and guarantees are issued by governmental entities, private insurers and the mortgage poolers. There can be no assurance that the private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements. Mortgage pools underlying mortgage securities offered by non-governmental issuers more frequently include second mortgages, high loan-to-value ratio mortgages and manufactured housing loans, in addition to commercial mortgages and other types of mortgages where a government or government-sponsored entity guarantee is not available. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of a mortgage-backed security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their mortgages. For these reasons, the loans underlying these securities have had in many cases higher default rates than those loans that meet government underwriting requirements. The risk of non-payment is greater for mortgage-related securities that are backed by loans that were originated under weak underwriting standards, including loans made to borrowers with limited means to make repayment. A level of risk exists for all loans, although, historically, the poorest performing loans have been those classified as subprime. Other types of privately issued mortgage-related securities, such as those classified as pay-option adjustable rate or Alt-A, have also performed poorly.

Privately-issued mortgage-backed securities are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-related securities held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans. Privately-issued mortgage-backed securities include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. Many of the risks of investing in CMBS reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants.

The risks associated with mortgage-backed securities are elevated in distressed economic, market, health and labor conditions, notably, increased levels of unemployment, delays and delinquencies in payments of mortgage and rent obligations, and uncertainty regarding the effects and extent of government intervention with respect to mortgage payments and other economic matters.

Delinquencies, defaults and losses on residential mortgage loans may increase substantially over certain periods, which may affect the performance of the mortgage-backed securities in which the Fund may invest. Mortgage loans backing privately-issued mortgage-backed securities are more sensitive to economic factors that could affect the ability of borrowers to pay their obligations under the mortgage loans backing these securities. In addition, housing prices and appraisal values in many states and localities over certain periods have declined or stopped appreciating. A sustained decline or an extended flattening of those values may result in additional increases in delinquencies and losses on mortgage-backed securities generally (including the mortgaged-backed securities that the Fund may invest in as described above). Adverse changes in market conditions and regulatory climate may reduce the cash flow which the Fund, to the extent it invests in mortgage-backed securities or other asset-backed securities, receives from such securities and increase the incidence and severity of credit events and losses in respect of such securities. In the event that interest rate spreads for mortgage-backed securities and other asset-backed securities widen following the purchase of such assets by the Fund, the market value of such securities is likely to decline and, in the case of a substantial spread widening, could decline by a substantial amount. Furthermore, adverse changes in market conditions may result in reduced liquidity in the market for mortgage-backed securities and other asset-backed securities (including the mortgage-backed securities and other asset-backed securities in which the Fund may invest) and an unwillingness by banks, financial institutions and investors to extend credit to servicers, originators and other participants in the market for mortgage-backed and other asset-backed securities. As a result, the liquidity and/or the market value of any mortgage-backed or asset-backed securities that are owned by the Fund may experience declines after they are purchased by the Fund.

CMOs are debt obligations collateralized by mortgage loans or mortgage pass-through securities (collectively “Mortgage Assets”). Payments of principal and interest on the Mortgage Assets and any reinvestment income are used to make payments on the CMOs. CMOs are issued in multiple classes. Each class has a fixed or floating rate and a stated maturity or final distribution date. The

principal and interest on the Mortgage Assets may be allocated among the classes in a number of different ways. Certain classes will, as a result of the allocation, have more predictable cash flows than others. As a general matter, the more predictable the cash flow, the lower the yield relative to other Mortgage Assets. The less predictable the cash flow, the higher the yield and the greater the risk. The Fund may invest in any class of CMO, including classes that vary inversely with interest rates and may be more volatile and sensitive to prepayment rates.

The principal and interest on the Mortgage Assets comprising a CMO may be allocated among the several classes of a CMO in many ways. The general goal in allocating cash flows on Mortgage Assets to the various classes of a CMO is to create certain tranches on which the expected cash flows have a higher degree of predictability than do the underlying Mortgage Assets. As a general matter, the more predictable the cash flow is on a particular CMO tranche, the lower the anticipated yield on that tranche at the time of issue will be relative to the prevailing market yields on the Mortgage Assets. As part of the process of creating more predictable cash flows on certain tranches of a CMO, one or more tranches generally must be created that absorb most of the changes in the cash flows on the underlying Mortgage Assets. The yields on these tranches are generally higher than prevailing market yields on other mortgage related securities with similar average lives. Principal prepayments on the underlying Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates. Because of the uncertainty of the cash flows on these tranches, the market prices and yields of these tranches are more volatile and may increase or decrease in value substantially with changes in interest rates and/or the rates of prepayment. Due to the possibility that prepayments (on home mortgages and other collateral) will alter the cash flow on CMOs, it is not possible to determine in advance the final maturity date or average life. Faster prepayment will shorten the average life and slower prepayments will lengthen it. In addition, if the collateral securing CMOs or any third party guarantees are insufficient to make payments, the Fund could sustain a loss.

CMBS are generally multi-class or pass-through securities backed by a mortgage loan or a pool of mortgage loans secured by commercial property, such as industrial and warehouse properties, office buildings, retail space and shopping malls, multifamily properties and cooperative apartments. The commercial mortgage loans that underlie CMBS are generally not amortizing or not fully amortizing. That is, at their maturity date, repayment of their remaining principal balance or “balloon” is due and is repaid through the attainment of an additional loan or sale of the property. An extension of a final payment on commercial mortgages will increase the average life of the CMBS, generally resulting in a lower yield for discount bonds and a higher yield for premium bonds.

CMBS are subject to credit risk and prepayment risk. Although prepayment risk is present, it is of a lesser degree in the CMBS market than in the residential mortgage market; commercial real estate property loans often contain provisions that substantially reduce the likelihood that such securities will be prepaid (e.g., significant prepayment penalties on loans and, in some cases, prohibition on principal payments for several years following origination).

U.S. Treasury and Government Securities

The U.S. government securities that the Fund may purchase include U.S. Treasury bills, notes and bonds, all of which are direct obligations of the U.S. Government. In addition, the Fund may purchase securities issued or guaranteed by agencies and instrumentalities of the U.S. Government which are backed by the full faith and credit of the United States. Among the agencies and instrumentalities issuing these obligations are the Government National Mortgage Association and the Federal Housing Administration. Also, the Fund may purchase securities issued by agencies and instrumentalities which are not backed by the full faith and credit of the United States, but whose issuing agency or instrumentality has the right to borrow, to meet its obligations, from the U.S. Treasury. Among these agencies and instrumentalities are FNMA, the FHLMC and the Federal Home Loan Banks. No assurance can be given that these initiatives will be successful. Further, the Fund may purchase securities issued by agencies and instrumentalities which are backed solely by the credit of the issuing agency or instrumentality. Among these agencies and instrumentalities is the Federal Farm Credit System. Because these securities are not backed by the full faith and credit of the United States, there is a risk that the U.S. Government will not provide financial support to these agencies if it is not obligated to do so by law. The maximum potential liability of the issuers of some U.S. government securities held by the Fund may greatly exceed their current resources, including their legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future. The interest from U.S. government securities generally is not subject to state and local taxation.

Money Market Investments

Money market instruments may be adversely affected by market and economic events, such as a sharp rise in prevailing short-term interest rates; adverse developments in the banking industry, which issues or guarantees many money market securities; adverse economic, political or other developments affecting domestic issuers of money market securities; changes in the credit quality of issuers; and default by a counterparty. These securities may be subject to federal income, state income and/or other taxes. Instead of investing in money market instruments directly, the Fund may invest in an affiliated or unaffiliated money market fund. Recent actions by governmental authorities in response to the economic disruptions caused by the COVID-19 pandemic have included dramatic reductions in interest rates, which in some cases could result in negative rates on investments in money market funds and similar cash management products. During unusual market conditions, the Fund may invest up to 100% of its assets in cash or cash equivalents temporarily, which may be inconsistent with its investment objective(s) and other policies.

Preferred Securities

Preferred securities are subject to risks applicable generally to equity securities. In addition, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt, so the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred securities may pay fixed or adjustable rates of return. Like fixed-income securities, preferred stock generally decreases in value if interest rates rise and increases in value if interest rates fall.

Municipals

Municipal securities (also referred to as municipal obligations) include debt obligations of states, territories or possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, such as local or regional governments. The income on municipal securities is generally exempt from federal income tax at the time of issuance, in the opinion of bond counsel or other counsel to the issuers of such securities. However, the Fund may purchase municipal securities that pay interest that is subject to the federal alternative minimum tax, and municipal securities on which the interest payments are taxable. These securities typically are “general obligation” or “revenue” bonds, notes or commercial paper, including participations in lease obligations and installment purchase contracts of municipalities. General obligation bonds are secured by the issuer’s full faith and credit including its taxing power for payment of principal and interest. Revenue bonds, however, are generally payable from a specific revenue source. They are issued for a wide variety of projects such as financing public utilities, hospitals, housing, airports, highways and educational facilities. These types of bonds involve the risk that the tax or other revenues so derived will not be sufficient to meet interest and or principal payment obligations. These obligations may have fixed, variable or floating rates.

Because the Fund may invest in municipal securities, the Fund may be affected significantly by the economic, regulatory, legislative, tax or political developments affecting the ability of issuers of municipal securities to pay interest or repay principal. The risks of municipal securities generally depend on the financial and credit status of the issuer and may rely on a specific stream of revenue associated with a project or other revenue source. Thus, adverse developments related to a municipality’s ability to raise revenue, including through its taxing authority, or the failure of specific revenues to materialize would negatively impact such investments. Changes in the financial health of an issuer of municipal securities may make it difficult for the issuer to make interest and principal payments when due. Some municipalities have had significant financial problems recently, and these and other municipalities could, potentially, continue to experience significant financial problems resulting from lower tax revenues and/or decreased aid from state and local governments in the event of an economic downturn. In addition, adverse legislative, tax, regulatory, demographic or political changes may negatively impact the Fund’s investments in municipal securities. These events could decrease the Fund’s income and/or adversely affect the Fund’s performance and investments. Municipal securities also involve the risk that an issuer may call securities for redemption, which could force the Fund to reinvest the proceeds at a lower rate of interest, and the value of municipal securities may be affected by the rights of municipal security holders.

Municipal securities may be more susceptible to downgrades, defaults or loss of tax or other revenue during recessions or similar periods of economic stress. Factors contributing to the financial stress on municipalities may include lower property tax collections as a result of lower home values, lower sales tax revenue as a result of consumers cutting back spending and lower income tax revenue as a result of a higher unemployment rate. In addition, because some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund associated with investments in such municipal securities could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. If such events occur, the value of the security could decrease or the value could be lost entirely, and it may be difficult or impossible for the Fund to sell the security at the time and the price that normally prevails in the market.

For example, the current COVID-19 pandemic has significantly stressed the financial resources of many municipalities and other issuers of municipal securities, which may impair their ability to meet their financial obligations and may harm the value or liquidity of the Fund’s investments in municipal securities (or the income generated by such investments). In particular, responses by municipalities to the COVID-19 pandemic have caused disruptions in business activities. These and other effects of the COVID-19 pandemic, such as increased unemployment levels, have impacted tax and other revenues of municipalities and other issuers of municipal securities and the financial conditions of such issuers. As a result, there is an increased budgetary and financial pressure on municipalities and other issuers of municipal securities and heightened risk of default or other adverse credit or similar events for issuers of municipal securities, which would adversely impact the Fund’s investments.

In addition, the ability of an issuer to make payments or repay interest may be affected by litigation or bankruptcy. In the event of bankruptcy of such an issuer, the Fund investing in the issuer’s securities could experience delays in collecting principal and interest, and the Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may, in some instances, take possession of, and manage, the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt. Municipal securities are subject to, among other risks, credit and interest rate risk and market and geopolitical risk.

Because many municipal securities are issued to finance similar projects (such as those relating to education, health care, housing, transportation, and utilities), conditions in those sectors may affect the overall municipal securities market. In addition, changes in the financial condition of an individual municipal issuer can affect the overall municipal market. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the supporting taxation or the inability to collect revenues for the specific project or specific assets.

Some municipal securities are subject to the risk that the U.S. Internal Revenue Service (“IRS”) may determine that an issuer has not complied with applicable tax requirements (or the occurrence of other adverse tax developments) and that interest from the municipal security is taxable, which may result in a significant decline in the value of the security. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from the federal alternative minimum tax. In addition, while interest earned on municipal securities is generally not subject to federal income tax, any interest earned on taxable municipal securities is fully taxable at the federal level and may be subject to state and/or local income tax. Municipal securities may be less liquid than taxable bonds and there may be less publicly available information on the financial condition of municipal security issuers than for issuers of other securities, and the investment performance of the Fund investing in municipal securities may therefore be more dependent on the analytical abilities of the Adviser than if the Fund held other types of investments such as stocks or taxable bonds. The secondary market for municipal securities also tends to be less well developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell municipal securities it holds at attractive prices or value municipal securities. In addition, the demand for municipal securities is strongly influenced by the value of tax-exempt income to investors and lower income tax rates could reduce the advantage of owning municipal securities, which may also adversely affect the value and liquidity of municipal securities.

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.

High Yield Securities

Fixed-income securities that are not investment grade are commonly referred to as “junk bonds” or high yield, high risk securities. These securities offer a higher yield than other higher rated securities, but they carry a greater degree of risk. High yield securities are subject to greater risk of loss of income and principal than higher rated securities and may be considered speculative by the major credit rating agencies. High yield securities may be issued by companies that are restructuring, are smaller and less creditworthy or are more highly indebted than other companies. This means that they may have more difficulty making scheduled payments of principal and interest. Changes in the value of high yield securities are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade securities.

In recent years, there has been a broad trend of weaker or less restrictive covenant protections in the high yield market. Among other things, under such weaker or less restrictive covenants, borrowers might be able to exercise more flexibility with respect to certain activities than borrowers who are subject to stronger or more protective covenants. For example, borrowers might be able to incur more debt, including secured debt, return more capital to shareholders, remove or reduce assets that are designated as collateral securing high yield securities, increase the claims against assets that are permitted against collateral securing high yield securities or otherwise manage their business in ways that could impact creditors negatively. In addition, certain privately held borrowers might be permitted to file less frequent, less detailed or less timely financial reporting or other information, which could negatively impact the value of the high yield securities issued by such borrowers. Each of these factors might negatively impact the high yield securities held by the Fund.

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.

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.

Restricted Securities

The Fund’s investments may include securities which are subject to resale restrictions. These securities could have the effect of increasing the level of Fund illiquidity to the extent the Fund may be unable to sell or transfer these securities due to restrictions on transfers or on the ability to find buyers interested in purchasing the securities. Additionally, the market for certain investments deemed liquid at the time of purchase may become illiquid under adverse market or economic conditions. The illiquidity of the market, as well as the lack of publicly available information regarding these securities, may also adversely affect the ability to arrive at a fair value for certain securities at certain times and could make it difficult for the Fund to sell certain securities. If the Fund is forced to sell an illiquid security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.

Derivatives

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.

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 fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.

Repurchase Agreements

Repurchase agreements are fixed-income securities in the form of agreements backed by collateral. These agreements typically involve the acquisition by the Fund of securities from the selling institution (such as a bank or a broker-dealer), coupled with the agreement that the selling institution will repurchase the underlying securities at a specified price and at a fixed time in the future (or on demand, if applicable). The underlying securities which serve as collateral for the repurchase agreements entered into by the Fund may include U.S. government securities, municipal securities, corporate debt obligations, and common and preferred stock and may be of below investment grade quality. These securities are marked-to-market daily in order to maintain full collateralization (typically purchase price plus accrued interest). The use of repurchase agreements involves certain risks. For example, if the selling institution defaults on its obligation to repurchase the underlying securities at a time when the value of the securities has declined, the Fund may incur a loss upon disposition of them. The risk of such loss may be greater when utilizing collateral other than U.S. government securities. In the event of an insolvency or bankruptcy by the selling institution, the Fund’s right to control the collateral could be affected and result in certain costs and delays. Additionally, if the proceeds from the liquidation of such collateral after an insolvency were less than the repurchase price, the Fund could suffer a loss. Fund procedures are followed that are designed to minimize such risks.

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.

Government and other public debt, including municipal obligations in which the Fund may invest, can be adversely affected by large and sudden changes in local and global economic conditions that result in increased debt levels. Although high levels of government and other public debt do not necessarily indicate or cause economic problems, high levels of debt may create certain systemic risks if sound debt management practices are not implemented. A high debt level may increase market pressures to meet an issuer’s funding needs, which may increase borrowing costs and cause a government or public or municipal entity to issue additional debt, thereby increasing the risk of refinancing. A high debt level also raises concerns that the issuer may be unable or unwilling to repay the principal or interest on its debt, which may adversely impact instruments held by the Fund that rely on such payments. Governmental and quasi-governmental responses to certain economic or other conditions may lead to increasing government and other public debt, which heighten these risks. Unsustainable debt levels can lead to declines in the value of currency, and can prevent a government from implementing effective counter-cyclical fiscal policy during economic downturns, can generate or contribute to

an economic downturn or cause other adverse economic or market developments, such as increases in inflation or volatility. Increasing government and other public debt may adversely affect issuers, obligors, guarantors or instruments across a variety of asset classes.

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

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’s 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.

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 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.

Cash Transactions Risk

Unlike certain ETFs, a Fund may effect its creations and redemptions in cash or partially in cash. As a result, an investment in a Fund may be less tax-efficient than an investment in such ETFs. Other ETFs generally are able to make in-kind redemptions and avoid realizing gains in connection with transactions designed to raise cash to meet redemption requests. If a Fund effects a portion of redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds, which also involves transaction costs. If a Fund recognizes gain on these sales, this generally will cause a Fund to recognize gain it might not otherwise have recognized if it were to distribute portfolio securities in-kind, or to recognize such gain sooner than would otherwise be required. A Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at a Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different ETF.

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.

Borrowing

The Fund is permitted to borrow for temporary purposes (such as to satisfy redemption requests, to remain fully invested in anticipation of expected cash inflows and to settle transactions). Any borrowings by the Fund are subject to the requirements of the 1940 Act. Borrowings are also subject to the terms of any credit agreement between the Fund and lender(s). Fund borrowings may be equal to as much as 33 1/3% of the value of the Fund’s total assets (including such borrowings) less the Fund’s liabilities (other than borrowings). The Fund will not purchase additional investments while outstanding borrowings exceed 5% of the value of its total assets.

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.

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.

Banking Industry

Investment opportunities in investment grade securities may be concentrated in the banking industry. Under normal conditions, the Fund will invest more than 25% of its total assets in securities issued by issuers in the banking industry. As a result, the Fund may have a high concentration of investments in the banking industry. The banking industry can be affected by global and local economic conditions, such as the levels and liquidity of the global and local financial and asset markets, the absolute and relative level and volatility of interest rates and equity prices, investor sentiment, inflation, and the availability and cost of credit. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operations and profitability of the banking industry. Because the Fund’s investments will be concentrated in the banking industry, factors that have an adverse impact on this industry may have a disproportionate impact on the Fund’s performance.

Temporary Investments

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

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 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.

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.

Investment Selection Process

The Fund seeks to invest in 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. In assessing issuers for which quantitative data is limited, subjective judgments may serve as the primary basis for Calvert’s evaluation. The responsible investment criteria of the Fund may be changed by the Board without shareholder approval.

The Fund may invest in a fixed or floating-rate income security before Calvert has completed its evaluation of the security’s responsible investment characteristics if, in the opinion of the portfolio manager, the timing of the purchase is appropriate given market conditions. Factors that a portfolio manager may consider in making such an investment decision include, but are not limited to, (i) prevailing market prices, (ii) liquidity, (iii) bid-ask spreads, (iv) market color, and (v) availability. Following any such investment in a security, Calvert will evaluate the issuer to determine if it operates in a manner that is consistent with the Fund’s responsible investment criteria. A security will also be sold (in accordance with the Adviser’s guidelines and at a time and in a manner that is determined to be in the best interests of shareholders) if the Adviser determines that the issuer does not operate in a manner consistent with the Fund’s responsible investment criteria. As described above, or 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 a 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 0.24% 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 Brian S. Ellis, CFA and Eric Jesionowski, who are jointly and primarily responsible for the day-to-day management of the Fund.

Messrs. Ellis and Jesionowski are Executive Directors or Morgan Stanley Investment Management Inc., manage other funds and have been employed by the Morgan Stanley organization for more than five years.

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.

In connection with certain cash creations, the Adviser may provide the creating Authorized Participants with information regarding securities that the Fund would be willing to purchase with the proceeds of the cash creation, which may not be the current holdings of the Fund. In certain cases, the Fund may purchase such securities from an Authorized Participant that has submitted a creation order. Regardless of whether the Fund purchases securities with the proceeds of a cash creation order from the creating Authorized Participant, the Authorized Participant may be assessed a variable charge to compensate the Fund for the costs associated with purchasing the applicable securities, as described in the SAI. For more information, see the SAI.

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 monthly 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. It is not anticipated that any portion of the distributions by the Fund would qualify for a lower tax rate as qualified dividend income. Further, such distributions are not anticipated to be eligible for a dividends-received deduction for corporate shareholders.

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 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.

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.

The Calvert Principles for Responsible Investment

We believe that most corporations deliver benefits to society, through their products and services, creation of jobs, payment of taxes and the sum of their behaviors.

In addition to this Prospectus, the Fund has an SAI, dated January [ ], 2023 (as may be supplemented from time to time), which contains additional, more detailed information about the Trust and the Fund. The SAI is incorporated by reference into this Prospectus and, therefore, legally forms a part of this Prospectus.
