Eaton Vance \| **Fund Summary**

Eaton Vance CLO Investment Grade Income ETF

**Investment Objective**

Eaton Vance CLO Investment Grade Income ETF (the "Fund") seeks current income, with a secondary objective of capital preservation.

**Fees and Expenses**

**Annual Fund Operating Expenses<sup>1</sup>**(expenses that you pay each year as a percentage of the value of your investment)

---

| | |
|:---|:---|
| Management Fee<sup>1</sup>  | 0.20% |
| Other Expenses<sup>2</sup>  | 0.00% |
| Total Annual Fund Operating Expenses | 0.20% |

| | |
|:---|:---|
| 1 | 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 all of 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** |
| $20 | $64 |

---

**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 yet commenced operations as of the most recent fiscal year end, no portfolio turnover rate is available for the Fund.

**Principal Investment Strategies**

The Fund is an actively managed exchange-traded fund ("ETF") and does not seek to track the performance of any particular index. The Fund normally invests at least 80% of its net assets (plus borrowings for investment purposes) in investment grade-rated debt tranches of collateralized loan obligations ("CLOs") of any maturity. Investment grade CLO securities are rated inclusive and above BBB- by S&P Global Ratings or Baa3 Moody's Investors Service, Inc. (or equivalent rating issued by a nationally recognized statistical rating organization ("NRSRO")), or if unrated, determined to be of comparable credit quality by the Adviser. The Fund will not invest in any CLO equity security or in any CLO debt security rated below BB-/Ba3 or if unrated, determined to be of comparable credit quality by the Adviser. For purposes of complying with its 80% investment policy, the Fund may invest in CLO investments directly or indirectly, for example by investing in closed-end funds and exchange-traded funds ("ETFs") or derivatives that provide investment and economic exposure to investment-grade rated CLO debt investments. The Fund will provide shareholders with at least sixty days' written notice of any change in this 80% investment policy.

For purposes of the Fund's investment policies, CLOs are trusts that are typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans, and including "covenant lite" loans, which have few or no financial maintenance covenants. The Fund may purchase CLO securities both in the primary (e.g., purchased directly from the issuer) and secondary markets. The Adviser uses a bottom-up analysis to select CLO investments which considers several factors, including an assessment of the CLO manager, the CLO's underlying collateral, an analysis of the CLO's documentation and structural terms. The Fund's portfolio is constructed using this security-level analysis, combined with a top-down overlay which incorporates the Adviser's credit views as well as risk factor positioning. The Fund intends to invest primarily in CLO securities that are U.S.-dollar denominated. However, the Fund may from time to time invest up to 20% of its net assets in CLO securities that are denominated in foreign currencies. To the extent the Fund invests in non-U.S. dollar denominated securities, it may seek to hedge its exposure to foreign currency to U.S. dollars, as described more fully below.

Eaton Vance \| **Fund Summary**

Eaton Vance CLO Investment Grade Income ETF (Con't)

The Fund may purchase up to 20% of its net assets in other types of investment grade-rated fixed-rate or floating-rate bonds that are not CLOs; shares of ETF and closed end funds; below investment grade CLOs, non-US denominated investment grade CLOs; and private credit CLOs. Private credit CLOs, often commonly referred to as "middle-market" CLOs, are collateralized by directly-originated loans to generally small or medium-sized firms and/or by loans of a small or medium size. The Fund may invest a portion of its assets in cash or other short-term instruments, such as money market instruments or money market funds, while deploying new capital, for liquidity management purposes, managing redemptions, or for defensive purposes, including navigating unusual market conditions.

The Fund may invest in derivatives in order to seek to mitigate risks associated with the Fund's existing portfolio of CLO securities. The Fund's use of derivatives will be limited to currency forward contracts or futures contracts to hedge certain foreign currency exposure. Forward contracts may be used by the Fund for hedging purposes to protect against uncertainty in the level of future foreign currency exchange rates, such as when the Fund anticipates purchasing or selling a foreign security. For example, this technique would allow the Fund to "lock in" the U.S. dollar price of the security. Forward contracts may also be used to attempt to protect the value of the Fund's existing holdings of foreign securities. The Fund's portfolio management utilizes the information provided by, and the expertise of affiliates in making investment decisions. 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.

When deemed by the Adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the Adviser considers environmental, social and/or governance issues (referred to as ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Fund's portfolio.

**Principal Risks**

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. Investments in the Fund involve risks and you should not rely on the Fund as a complete investment program. The relative significance of each risk factor summarized below may change over time and you should review each risk factor carefully because any one or more of these risks may result in losses to the Fund. The principal risks of investing in the Fund include:

• **Collateralized Loan Obligations Risk.** CLOs are a type of asset-backed security that is typically structured as a trust collateralized by a pool of loans. The cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The risks of an investment in a CLO depend largely on the type of the collateral securities and the class or tranche of the instrument in which the Fund invests. In addition to the risks normally associated with fixed income securities, such as interest rate risk, default risk, credit risk and liquidity risk, CLOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the Fund may invest in CLOs that are subordinate to other classes; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. The Fund and other investors in CLOs ultimately bear the credit and interest rate risks of the underlying collateral. CLOs, and their underlying loan obligations, are typically not registered for sale to the public and therefore are subject to certain restrictions on transfer and sale, potentially subjecting them to increased liquidity risk as compared to other types of securities. As a result, the proceeds from the sale of CLO securities may not be readily available to meet the Fund's redemption or other obligations and the Fund may be unable to acquire or dispose of the securities at a price and time the Fund deems advantageous.

CLOs in which the Fund invests may be managed by investment advisers not affiliated with the Adviser. CLO managers are responsible for selecting, managing and replacing the underlying bank loans within a CLO. CLO managers may have limited operating histories and, may be subject to conflicts of interests, including managing the assets of other clients or other investment vehicles, or receiving fees that incentivize maximizing the yield, and indirectly the risk, of a CLO. Adverse developments with respect to a CLO manager may adversely impact the performance of the CLO securities in which the Fund invests.<br>

• **Loan Risks.** Investments in loans are subject to the risks generally associated with other debt obligations (such as credit and interest rate risk). Loans are also subject to additional risks, including subordination to other creditors, no collateral or limited rights in collateral, increased liquidity risks and lack of publicly available information. Loans are subject to the risk of default in the payment of interest or principal, which will result in a reduction of income or other losses to the Fund, and a potential decrease in the Fund's NAV. Loans are traded in a private, unregulated inter-dealer or interbank resale market and are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund's ability to buy or sell loans (thus affecting their liquidity) and may negatively impact the transaction price. It also may take longer than seven days for transactions in loans to settle. Due to the possibility of an extended loan settlement process, the Fund may hold additional cash, sell investments or temporarily borrow from banks or other lenders to meet short-term liquidity needs. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness of the issuer, the

**2**

Eaton Vance \| **Fund Summary**

Eaton Vance CLO Investment Grade Income ETF (Con't)

nature of the collateral securing the loan and possibly other factors. Loans with fewer covenants that restrict activities of the borrower may provide the borrower with more flexibility to take actions that may be detrimental to the loan holders and provide fewer investor protections in the event of such actions or if covenants are breached. The Fund may experience relatively greater realized or unrealized losses or delays and expense in enforcing its rights with respect to loans with fewer restrictive covenants. Loans to entities located outside of the U.S. may have substantially different lender protections and covenants as compared to loans to U.S. entities and generally involve greater and additional risks. The Fund may have difficulties and incur expense enforcing its rights with respect to loans and non-U.S. loans could be subject to bankruptcy laws that are materially different than in the U.S. Loans may be structured such that they are not securities under securities laws, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. Loans are also subject to risks associated with other types of income investments, including credit risk and risks of lower rated investments. In addition, bank loans are subject to the risk of default in the payment of interest or principal on a loan, which will result in a reduction of income to the Fund, and a potential decrease in the Fund's NAV. The risk of default on loans will increase in the event of an economic downturn or a substantial increase in interest rates. Because some loans rank lower in priority of payment to other loans and other obligations, such loans present a greater degree of investment risk and may exhibit greater price volatility.<br>

• **Covenant Lite Loans.** Some of the loans or other obligations in which the Fund may invest or obtain exposure to may be "covenant lite" loans or other obligations. Certain financial institutions may define "covenant lite" loans or securities differently. Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower's operations or assets and by providing certain information and consent rights to lenders. Covenant lite loans or securities, which have varied terms and conditions, may contain fewer or no restrictive covenants compared to other loans that might enable the Fund to, among other things, proactively enforce financial covenants or prevent undesired actions by the borrower. As a result, covenant lite loans generally carry greater risks because they allow borrowers to exercise more flexibility with respect to certain activities that may otherwise be limited or prohibited under similar loan obligations that are not covenant lite. In addition, the Fund may receive less or less frequent financial reporting from a borrower under a covenant-lite obligation, which may result in more limited access to financial information, difficulty evaluating the borrower's financial performance over time and delays in exercising rights and remedies in the event of a significant financial decline. The Fund may experience relatively greater difficulty or delays in enforcing its rights on its holdings of certain covenant lite loans and other similar obligations than its holdings of loans or securities with more traditional financial covenants, which may result in losses to the Fund. Many loans and similar debt obligations may not feature traditional financial maintenance covenants, which are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower's operations or assets and by providing certain information and consent rights to lenders.

• **Liquidity.** The Fund may make investments that are less liquid, illiquid or restricted or that may become illiquid or less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. Liquidity risk may be magnified in a market where credit spread and interest rate volatility is rising and where investor redemptions from fixed-income funds may be higher than normal. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value and may be unable to sell the security at all. Certain CLO securities may have limited liquidity in various market conditions, and in such instances will be less liquid than more senior or higher-rated CLOs. The price of CLO securities may rapidly decline if a large number of holders of the CLO securities decide to sell. The CLO market is smaller relative to other fixed-income instrument markets. Historic liquidity measures of CLOs may or may not be predictive of the liquidity of CLOs in the future. During adverse market conditions, there may be instances in which the market for trading CLOs becomes thin, or in extreme circumstances, particularly with respect to subordinate or lower-rated CLO tranches, may cease to exist during such period.

• **Asset-Backed Securities.** Asset-backed securities are subject to credit (such as a borrower's default on its mortgage obligation and the default or failure of a guarantee underlying the asset-backed security), interest rate and certain additional risks, including 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. Due to these and other risks, asset-backed securities may become more volatile in certain interest rate environments.

• **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). For example, a type of fixed-income securities in which the Fund may invest are corporate debt obligations. In addition to

**3**

Eaton Vance \| **Fund Summary**

Eaton Vance CLO Investment Grade Income ETF (Con't)

interest rate, credit and other risks, corporate debt obligations are also subject to factors directly related to the issuer, such as the credit rating of the corporation, the corporation's performance and perceptions of the corporation in the marketplace, and by factors not directly related to the issuer, such as general market liquidity, economic conditions and inflation. 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 is not limited as to the maturities (when a debt security provides its final payment) or durations (measure of interest rate sensitivity) of the securities in which it may invest. 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. 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.<br>

• **Credit and Interest Rate Risk.** Credit risk refers to the possibility that the issuer or guarantor of a security, or counterparty to a transaction, will be unable or unwilling or perceived to be unable or unwilling to make interest payments and/or repay the principal on its debt or otherwise honor its obligations, including the risk of default. In such instances, the value of the Fund could decline and the Fund could lose money. If an issuer's, guarantor's or counterparty's financial condition worsens, the credit quality of the issuer, guarantor or counterparty may deteriorate. Credit ratings may not be an accurate assessment of financial condition, liquidity or credit risk. Although credit ratings may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer, guarantor or counterparty, or the market's perception of the creditworthiness of an instrument or issuer, guarantor or counterparty can have a rapid, adverse effect on the instrument's value and liquidity and make it more difficult for the Fund to sell at an advantageous price or time. 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. A wide variety of market and economic factors can cause interest rates to rise or fall, including central bank monetary policy, rising inflation, disinflation or deflation, and changes in general economic conditions. 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 but the yield or income from new issuances of fixed-income securities generally decreases. Securities with longer durations will generally be more sensitive to changes in interest rates than securities with shorter durations. Fluctuations in interest rates may also affect the liquidity of and income generated by fixed-income instruments held by the Fund. The Fund may invest in variable and floating rate loans and other variable and floating rate securities. Although the value of 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. Changing interest rates may have unpredictable effects on the markets and may detract from Fund performance. A changing interest rate environment increases certain risks, including the potential for periods of market volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk).

• **High Yield Securities ("Junk Bonds").** The Fund's investments in high yield securities expose it to increased risks, including a substantial degree of credit and default risks. High yield securities may be issued by companies that are restructuring, are smaller and less creditworthy or are more highly leveraged or indebted than other companies or are financially distressed, and therefore they typically have more difficulty making scheduled payments of principal and interest than issuers of higher rated investments. High yield securities are subject to greater risk of loss (including substantial or total loss) of income and principal than higher rated securities and are considered speculative because of increased credit risk relative to higher rated fixed income investments. High yield securities are also subject to greater price volatility, including sudden and substantial decreases in price, and less liquidity than higher rated securities. High yield securities are particularly sensitive to adverse economic, market, industry or issuer-specific developments, which may result in an increased incidence of default. In the event of a default, the Fund may incur additional expenses to seek recovery or to negotiate new terms with a defaulting issuer.

• **Foreign Securities.** The Fund may invest in U.S. dollar-denominated securities issued by foreign governmental or corporate issuers. Investing in securities of foreign issuers involves some additional risks than securities of U.S. issuers. While foreign securities, including foreign money market securities, are subject to the same type of risks that pertain to domestic issuers, namely credit risk and interest rate risk, they are also subject to other additional risks. 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. In some foreign countries, there is also the risk of government expropriation, excessive taxation, political or social instability, economic sanctions or other similar governmental activity or diplomatic developments (including regional and global, military or other conflicts) that could affect an investment. There also can be difficulty obtaining and enforcing judgments against issuers in foreign countries. Governmental interventions or other actions can have a significant effect on the economic conditions in foreign countries, which also may adversely affect the Fund's investments in foreign issuers.

• **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

**4**

Eaton Vance \| **Fund Summary**

Eaton Vance CLO Investment Grade Income ETF (Con't)

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 their discretion choose not to hedge against currency risk. In addition, certain market conditions may make it impossible or uneconomical to hedge against currency risk.<br>

• **Derivatives.** Derivatives and other similar instruments that create synthetic exposure often are subject to risks similar to those of the underlying asset or instrument, including market risk, and may be subject to additional risks, including imperfect correlation between the value of the derivative and the underlying asset, risks of default by the counterparty to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative instrument relates, risks that the transactions may not be liquid, risks arising from margin and payment requirements, risks arising from mispricing or valuation complexity and operational and legal risks. 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 change due to economic, geopolitical and other events that affect the U.S. and global markets generally, as well as those that affect or are perceived or expected to affect particular regions, countries, industries, companies, issuers, sectors, asset classes or governments. These types of events may be sudden and unexpected, and could adversely affect the value (or income generated by) and liquidity of the Fund's investments, which may in turn impact 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 or events, epidemics and pandemics, terrorism, conflicts, social unrest, recessions, inflation, interest rate changes, supply chain disruptions and the threat or actual imposition of tariffs, trade barriers and other protectionist or retaliatory measures) adversely interrupt or otherwise affect the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets or economies may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These types of events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance or value 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. The frequency and magnitude of resulting changes in the value of the Fund's investments cannot be predicted.

• **Distressed and Defaulted Securities.** Distressed and defaulted securities are speculative and involve substantial risks in addition to the risks of investing in high yield securities. The Fund will generally not receive interest payments on the distressed securities and the repayment of principal may also be subject to increased risk. These securities may present a substantial risk of default or may be in default at the time of investment, requiring the Fund to incur additional costs. The repayment of defaulted securities is also subject to significant uncertainties. The Fund may incur substantial expenses in seeking recovery upon a default in the payment of principal of or interest on its portfolio holdings.

• **LIBOR Discontinuance or Unavailability Risk.** The Fund's investments, payment obligations and financing terms may be based on floating rates, such as the London Interbank Offered Rates (collectively, "LIBOR"), Euro Interbank Offered Rate, Secured Overnight Financing Rate ("SOFR") and other similar types of reference rates (each, a "Reference Rate"). These Reference Rates are generally intended to represent the rate at which contributing banks may obtain short-term borrowings from each other within certain financial markets. London Interbank Offered Rate ("LIBOR") was the basic rate of interest used in lending transactions between banks on the London interbank market and has been widely used as a reference for setting the interest rate on loans globally. As a result of benchmark reforms, publication of LIBOR settings has ceased. Certain regulators and industry groups have taken actions to establish alternative reference rates (e.g., the SOFR, which measures the cost of overnight borrowings through repurchase agreement transactions collateralized with U.S. Treasury securities and is intended to replace U.S. dollar LIBORs with certain adjustments). These developments could negatively impact financial markets in general and present heightened risks, including with respect to the Fund's investments. As a result of the uncertainty and developments relating to the transition process, performance, price volatility, liquidity and value of the Fund and its assets may be adversely affected.

• **ETF Structure Risks.** 

*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. There can be no assurance that an active trading market for the Fund's shares will develop or be maintained. 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, such as during periods of market stress, and no other authorized participant creates or redeems, shares may trade at a discount to net asset value ("NAV") per share and possibly face trading halts and/or delisting. Authorized participant concentration risk may be heightened to the extent the Fund invests in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.<br>

*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

Eaton Vance CLO Investment Grade Income ETF (Con't)

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.

*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. You may pay significantly more or receive significantly less than the Fund's NAV per share during periods when there is a significant premium or discount. 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 the 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.<br>

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

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

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

• **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.

Please see "Additional Information About Fund Investment Strategies and Related Risks" in the Fund's prospectus for a more detailed description of risks of investing in the Fund. 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.eatonvance.com.

**Tax Information**

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

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

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

Eaton Vance High Income Municipal ETF

**Investment Objective**

Eaton Vance High Income Municipal ETF (the "Fund") seeks to provide high current income exempt from regular federal income tax.

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 all of 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** |
| $40 | $125 |

---

**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 yet commenced operations as of the most recent fiscal year end, no portfolio turnover rate is available for the Fund.

**Principal Investment Strategies**

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal obligations, the interest on which is exempt from regular federal income tax. This policy is fundamental and may not be changed without shareholder approval. The Fund may invest without limit in obligations the income from which is subject to the federal alternative minimum tax. The Fund will primarily invest in "high yield" municipal obligations under normal market conditions. For this purpose, "high yield" municipal obligations are municipal obligations rated at the time of investment either Baa or lower by Moody's Investors Service, Inc. ("Moody's"), or BBB or lower by either S&P Global Ratings ("S&P") or Fitch Ratings ("Fitch") or, if unrated, determined by the investment adviser to be of comparable quality. "High yield" municipal obligations rated below investment grade are also known as "junk bonds." The Fund may invest in securities in any rating category, including those in default. For purposes of rating restrictions, if securities are rated differently by two or more rating agencies, the lowest rating will be used for any Fund rating restrictions.

The Fund may invest up to 20% of its net assets in other debt obligations, including (but not limited to) taxable municipal obligations, U.S. Treasury securities and obligations of the U.S. Government, its agencies and instrumentalities ("Agency Securities"). The Fund may purchase or sell derivative instruments (such as residual interest bonds, futures contracts and options thereon, interest rate swaps, and forward rate contracts) for hedging purposes, to seek total return or as a substitute for the purchase or sale of securities. Derivative instruments used by the Fund will be counted toward the Fund's 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

In pursuing its objective, the Fund normally acquires municipal obligations with maturities of ten years or more, but may acquire securities with shorter maturities.

The Fund may invest 25% or more of its total assets in certain types of municipal obligations (such as general obligations, municipal leases, principal only municipal investments, revenue bonds and industrial development bonds) and in one or more states, territories

**8**

[Back to **Table of Contents**](#TOC_16872)

Eaton Vance \| **Fund Summary**

Eaton Vance High Income Municipal ETF (Con't)

and economic sectors (such as housing, hospitals, healthcare facilities or utilities). The Fund may invest in pooled investment vehicles, including exchange-traded funds ("ETFs"), to seek exposure to the municipal markets or municipal market sectors.

The Adviser's process for selecting obligations for purchase and sale emphasizes the creditworthiness of the issuer or other person obligated to repay the obligation and the relative value of the obligation in the market. In evaluating creditworthiness, the Adviser considers ratings assigned by rating agencies and generally performs additional credit and investment analysis. When deemed by the Adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the Adviser considers environmental, social and/or governance issues (referred to as ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Fund's portfolio.

The Fund may engage in relative value trading to take advantage of price appreciation opportunities or to realize capital losses. The fund also may trade securities to seek to minimize taxable capital gains to shareholders. A portion of the Fund's distributions generally will be subject to the federal alternative minimum tax. The Fund may not be suitable for investors subject to the federal alternative minimum tax.

**Principal Risks**

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. Investments in the Fund involve risks and you should not rely on the Fund as a complete investment program. The relative significance of each risk factor summarized below may change over time and you should review each risk factor carefully because any one or more of these risks may result in losses to the 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). For example, a type of fixed-income securities in which the Fund may invest are corporate debt obligations. In addition to interest rate, credit and other risks, corporate debt obligations are also subject to factors directly related to the issuer, such as the credit rating of the corporation, the corporation's performance and perceptions of the corporation in the marketplace, and by factors not directly related to the issuer, such as general market liquidity, economic conditions and inflation. 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 is not limited as to the maturities (when a debt security provides its final payment) or durations (measure of interest rate sensitivity) of the securities in which it may invest. 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. 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.

• **High Yield Securities ("Junk Bonds").** The Fund's investments in high yield securities expose it to increased risks, including a substantial degree of credit and default risks. High yield securities may be issued by companies that are restructuring, are smaller and less creditworthy or are more highly leveraged or indebted than other companies or are financially distressed, and therefore they typically have more difficulty making scheduled payments of principal and interest than issuers of higher rated investments. High yield securities are subject to greater risk of loss (including substantial or total loss) of income and principal than higher rated securities and are considered speculative because of increased credit risk relative to higher rated fixed income investments. High yield securities are also subject to greater price volatility, including sudden and substantial decreases in price, and less liquidity than higher rated securities. High yield securities are particularly sensitive to adverse economic, market, industry or issuer-specific developments, which may result in an increased incidence of default. In the event of a default, the Fund may incur additional expenses to seek recovery or to negotiate new terms with a defaulting issuer.

• **Credit and Interest Rate Risk.** Credit risk refers to the possibility that the issuer or guarantor of a security, or counterparty to a transaction, will be unable or unwilling or perceived to be unable or unwilling to make interest payments and/or repay the principal on its debt or otherwise honor its obligations, including the risk of default. In such instances, the value of the Fund could decline and the Fund could lose money. If an issuer's, guarantor's or counterparty's financial condition worsens, the credit quality of the issuer, guarantor or counterparty may deteriorate. Credit ratings may not be an accurate assessment of financial condition, liquidity or credit risk. Although credit ratings may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer, guarantor or counterparty, or the market's perception of the creditworthiness of an instrument or issuer, guarantor or counterparty can have a rapid, adverse effect on the instrument's value and liquidity and make it more difficult for the Fund to sell at an advantageous price or time. 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. A wide variety of market and economic factors

**9**

Eaton Vance \| **Fund Summary**

Eaton Vance High Income Municipal ETF (Con't)

can cause interest rates to rise or fall, including central bank monetary policy, rising inflation, disinflation or deflation, and changes in general economic conditions. 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 but the yield or income from new issuances of fixed-income securities generally decreases. Securities with longer durations will generally be more sensitive to changes in interest rates than securities with shorter durations. Fluctuations in interest rates may also affect the liquidity of and income generated by fixed-income instruments held by the Fund. The Fund may invest in variable and floating rate loans and other variable and floating rate securities. Although the value of 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. Changing interest rates may have unpredictable effects on the markets and may detract from Fund performance. A changing interest rate environment increases certain risks, including the potential for periods of market volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk).<br>

• **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 Federal National Mortgage Association or Federal Home Loan Mortgage Corporation, 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. U.S. government securities are also subject to interest rate risks and can exhibit price fluctuations resulting from increases or decreases in interest rates.

• **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 state or economic sector, it could be more sensitive to economic, business or political developments that affect such state or sector. Municipal securities and their issuers may be more susceptible to downgrade, loss of revenue, default and bankruptcy during 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.

• **Liquidity.** The Fund may make investments that are less liquid, illiquid or restricted or that may become illiquid or less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. Liquidity risk may be magnified in a market where credit spread and interest rate volatility is rising and where investor redemptions from fixed-income funds may be higher than normal. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value and may be unable to sell the security at all.

• **Market and Geopolitical Risk.** The value of your investment in the Fund is based on the values of the Fund's investments, which change due to economic, geopolitical and other events that affect the U.S. and global markets generally, as well as those that affect or are perceived or expected to affect particular regions, countries, industries, companies, issuers, sectors, asset classes or governments. These types of events may be sudden and unexpected, and could adversely affect the value (or income generated by) and liquidity of the Fund's investments, which may in turn impact 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 or events, epidemics and pandemics, terrorism, conflicts, social unrest, recessions, inflation, interest rate changes, supply chain disruptions and the imposition of tariffs, trade barriers and other protectionist or retaliatory measures) adversely interrupt or otherwise affect the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets or economies may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These types of events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance or value 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. The frequency and magnitude of resulting changes in the value of the Fund's investments cannot be predicted.

• **Derivatives.** Derivatives and other similar instruments that create synthetic exposure often are subject to risks similar to those of the underlying asset or instrument, including market risk, and may be subject to additional risks, including imperfect correlation between the value of the derivative and the underlying asset, risks of default by the counterparty to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative instrument relates, risks that the transactions may not be liquid, risks arising from margin and payment

requirements, risks arising from mispricing or valuation complexity and operational and legal risks. Certain derivative transactions may give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss.

• **ETF Structure Risks.** 

*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. There can be no assurance that an active trading market for the Fund's shares will develop or be maintained. 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, such as during periods of market stress, and no other authorized participant creates or redeems, shares may trade at a discount to net asset value ("NAV") per share and possibly face trading halts and/or delisting. Authorized participant concentration risk may be heightened to the extent the Fund invests in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.<br>

*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.<br>

*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. You may pay significantly more or receive significantly less than the Fund's NAV per share during periods when there is a significant premium or discount. 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 the 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.<br>

• **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.

• **Distressed and Defaulted Securities.** Distressed and defaulted securities are speculative and involve substantial risks in addition to the risks of investing in high yield securities. The Fund will generally not receive interest payments on the distressed securities and the repayment of principal may also be subject to increased risk. These securities may present a substantial risk of default or may be in default at the time of investment, requiring the Fund to incur additional costs. The repayment of defaulted securities is also subject to significant uncertainties. The Fund may incur substantial expenses in seeking recovery upon a default in the payment of principal of or interest on its portfolio holdings.

• **Taxability Risk**. Changes in tax laws or adverse determinations by the Internal Revenue Service ("IRS") may make the income from some municipal obligations taxable.

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

• **Residual Interest Bonds.** The Fund may enter into residual interest bond transactions, which expose the Fund to leverage and greater risk than an investment in a fixed-rate municipal bond. The interest payments that the Fund receives on the residual

**11**

interest bonds acquired in such transactions vary inversely with short-term interest rates, normally decreasing when short-term rates increase. The value and market for residual interest bonds are volatile and such bonds may have limited liquidity. As required by applicable accounting standards, the Fund records interest expense as a liability with respect to floating-rate notes and also records offsetting interest income in an amount equal to this expense. <br>

The Fund's distributions of interest on municipal obligations generally are not subject to federal income tax. The Fund's distributions from other portfolio securities may be subject to federal, state and/or local income taxes. Income derived from some municipal securities is subject to the federal alternative minimum tax. If the Fund makes any capital gain distributions, those distributions will normally be subject to federal and state income tax when they are paid, whether you take them in cash or reinvest them in Fund shares.

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

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

Eaton Vance CLO Investment Grade Income ETF

**Investment Objective**

The Fund seeks current income, with a secondary objective of capital preservation.

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 is an actively managed exchange-traded fund ("ETF") and does not seek to track the performance of any particular index. The Fund normally invests at least 80% of its net assets (plus borrowings for investment purposes) in investment grade-rated debt tranches of collateralized loan obligations ("CLOs") of any maturity. Investment grade CLO securities are rated inclusive and above BBB- by S&P Global Ratings or Baa3 Moody's Investors Service, Inc. (or equivalent rating issued by a nationally recognized statistical rating organization ("NRSRO")), or if unrated, determined to be of comparable credit quality by the Adviser. The Fund will not invest in any CLO equity security or in any CLO debt security rated below BB-/Ba3 or if unrated, determined to be of comparable credit quality by the Adviser. For purposes of complying with its 80% investment policy, the Fund may invest in CLO investments directly or indirectly, for example by investing in closed-end funds and exchange-traded funds ("ETFs") or derivatives that provide investment and economic exposure to investment-grade rated CLO debt investments. The Fund will provide shareholders with at least sixty days' written notice of any change in this 80% investment policy. For purposes of the Fund's investment policies, CLOs are trusts that are typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans, and including "covenant lite" loans, which have few or no financial maintenance covenants. The Fund may purchase CLO securities both in the primary (e.g., purchased directly from the issuer) and secondary markets. The Adviser uses a bottom-up analysis to select CLO investments which considers several factors, including an assessment of the CLO manager, the CLO's underlying collateral, an analysis of the CLO's documentation and structural terms. The Fund's portfolio is constructed using this security-level analysis, combined with a top-down overlay which incorporates the Adviser's credit views as well as risk factor positioning. The Fund intends to invest primarily in CLO securities that are U.S.-dollar denominated. However, the Fund may from time to time invest up to 20% of its net assets in CLO securities that are denominated in foreign currencies. To the extent the Fund invests in non-U.S. dollar denominated securities, it may seek to hedge its exposure to foreign currency to U.S. dollars, as described more fully below.

**Process**

The Fund may purchase up to 20% of its net assets in other types of investment grade-rated fixed-rate or floating-rate bonds that are not CLOs; shares of ETF and closed end funds; below investment grade CLOs, non-US denominated investment grade CLOs; and private credit CLOs. Private credit CLOs, often commonly referred to as "middle-market" CLOs, are collateralized by directly-originated loans to generally small or medium-sized firms and/or by loans of a small or medium size. The Fund may invest a portion of its assets in cash or other short-term instruments, such as money market instruments or money market funds, while deploying new capital, for liquidity management purposes, managing redemptions, or for defensive purposes, including navigating unusual market conditions.

The Fund may invest in derivatives in order to seek to mitigate risks associated with the Fund's existing portfolio of CLO securities. The Fund's use of derivatives will be limited to currency forward contracts or futures contracts to hedge certain foreign currency exposure. Forward contracts may be used by the Fund for hedging purposes to protect against uncertainty in the level of future foreign currency exchange rates, such as when the Fund anticipates purchasing or selling a foreign security. For example, this technique would allow the Fund to "lock in" the U.S. dollar price of the security. Forward contracts may also be used to attempt to protect the value of the Fund's existing holdings of foreign securities. The Fund's portfolio management utilizes the information provided by, and the expertise of affiliates in making investment decisions. 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.

When deemed by the Adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the Adviser considers environmental, social and/or governance issues (referred to as ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Fund's portfolio.

The Fund may change its principal investment strategies at any time without shareholder approval; however, you would be notified of any changes as required by applicable law.

Eaton Vance High Income Municipal ETF

**Investment Objective**

The Fund seeks to provide high current income exempt from regular federal income tax.

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**

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal obligations, the interest on which is exempt from regular federal income tax. This policy is fundamental and may not be changed without shareholder approval. The Fund may invest without limit in obligations the income from which is subject to the federal alternative minimum tax. The Fund will primarily invest in "high yield" municipal obligations under normal market conditions. For this purpose, "high yield" municipal obligations are municipal obligations rated at the time of investment either Baa or lower by Moody's Investors Service, Inc. ("Moody's"), or BBB or lower by either S&P Global Ratings ("S&P") or Fitch Ratings ("Fitch") or, if unrated, determined by the investment adviser to be of comparable quality. "High yield" municipal obligations rated below investment grade are also known as "junk bonds." The Fund may invest in securities in any rating category, including those in default. For purposes of rating restrictions, if securities are rated differently by two or more rating agencies, the lowest rating will be used for any Fund rating restrictions.

**Process**

The Fund may invest up to 20% of its net assets in other debt obligations, including (but not limited to) taxable municipal obligations, U.S. Treasury securities and obligations of the U.S. Government, its agencies and instrumentalities ("Agency Securities"). The Fund may purchase or sell derivative instruments (such as residual interest bonds, futures contracts and options thereon, interest rate swaps, and forward rate contracts) for hedging purposes, to seek total return or as a substitute for the purchase or sale of securities. Derivative instruments used by the Fund will be counted toward the Fund's 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

In pursuing its objective, the Fund normally acquires municipal obligations with maturities of ten years or more, but may acquire securities with shorter maturities.

The Fund may invest 25% or more of its total assets in certain types of municipal obligations (such as general obligations, municipal leases, principal only municipal investments, revenue bonds and industrial development bonds) and in one or more states, territories and economic sectors (such as housing, hospitals, healthcare facilities or utilities). The Fund may invest in pooled investment vehicles, including exchange-traded funds ("ETFs"), to seek exposure to the municipal markets or municipal market sectors.

The Adviser's process for selecting obligations for purchase and sale emphasizes the creditworthiness of the issuer or other person obligated to repay the obligation and the relative value of the obligation in the market. In evaluating creditworthiness, the Adviser considers ratings assigned by rating agencies and generally performs additional credit and investment analysis. When deemed by the Adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the Adviser considers environmental, social and/or governance issues (referred to as ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Fund's portfolio.

The Fund may engage in relative value trading to take advantage of price appreciation opportunities or to realize capital losses. The fund also may trade securities to seek to minimize taxable capital gains to shareholders. A portion of the Fund's distributions generally will be subject to the federal alternative minimum tax. The Fund may not be suitable for investors subject to the federal alternative minimum tax.

The Fund may change its principal investment strategies at any time without shareholder approval; however, you would be notified of any changes as required by applicable law.

Additional Information About Fund Investment Strategies and Related Risks

&nbsp;&nbsp;&nbsp; *This section discusses additional information relating to Fund investment strategies, other types of investments that the Fund may make and related risk factors. "Fund" as used herein and in the remainder of this Prospectus refers to each Fund listed on the cover page of this Prospectus (unless otherwise noted). Fund investment practices and limitations are described in more detail in the Statement of Additional Information ("SAI"), which is incorporated by reference and legally is a part of this Prospectus. For details on how to obtain a copy of the SAI and other reports and information, see the back cover of this Prospectus.*<br>

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

The name, investment objective and/or policies of the Fund may be similar to other funds advised by the Adviser or its affiliates. However, the investment results of the Fund may be higher or lower than, and there is no guarantee that the investment results of the Fund will be comparable to, any such other funds for any period of time.

The Fund may be more significantly affected by purchases and redemptions of its Creation Units (as defined below) than a fund with relatively greater assets under management would be affected by purchases and redemptions of its shares. As compared to a larger fund, the Fund is more likely to sell a comparatively large portion of its portfolio to meet significant Creation Unit redemptions or invest a comparatively large amount of cash to facilitate Creation Unit purchases, in each case when the Fund otherwise would not seek to do so. Such transactions may cause the Fund to make investment decisions at inopportune times or prices or miss attractive investment opportunities. Such transactions may also accelerate the realization of taxable income if sales of securities resulted in gains and the Fund redeems Creation Units for cash, or otherwise cause the Fund to perform differently than intended. While such risks may apply to funds of any size, such risks are heightened in funds with fewer assets under management.

**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-backed 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, convertible securities, 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). For example, a type of fixed-income securities in which the Fund may invest are corporate debt obligations. In addition to interest rate, credit and other risks, corporate debt obligations are also subject to factors directly related to the issuer, such as the credit rating of the corporation, the corporation's performance and perceptions of the corporation in the marketplace, and by factors not directly related to the issuer, such as general market liquidity, economic conditions and inflation. 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).

Fixed income and other debt instruments, including mortgage- and other asset-backed securities, are subject to prepayment risk, which is the risk that the principal of such obligation is paid earlier than expected, such as in the case of refinancing. This risk is increased during periods of declining interest rates and prepayments may reduce the Fund's yield or income as a result of reinvesting the income or other proceeds in lower yielding securities or instruments. These investments are also subject to extension risk, which is the risk that the principal of such obligation is paid slower or later than expected. This may negatively affect Fund returns, as the value of the investment decreases when principal payments are made later than expected. This risk is elevated during periods of increasing interest rates. In addition, because principal payments are made later than expected, the investment's duration may extend (and result in increased interest rate risk) and the Fund may be prevented from investing proceeds it would otherwise have received at the higher prevailing interest rates. Prepayments and extensions may result in a security or debt instrument offering less potential for gains during periods of declining interest rates or rising interest rates, respectively.

The Fund is not limited as to the maturities (when a debt security provides its final payment) or durations (measure of interest rate sensitivity) of the securities in which it may invest. 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

**15**

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

greater volatility because there is less certainty that principal and interest payments will be made as scheduled. The Fund may be subject to liquidity risk, which 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. 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.

**Corporate Debt Obligations**

Corporate debt obligations are fixed-income securities issued by private corporations. The investment return of corporate debt obligations reflects interest earnings and changes in the market value of the security. The market value of a corporate debt obligation may be expected to rise and fall inversely with interest rates generally. There also exists the risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument or at all. Debtholders, as creditors, have a prior legal claim over common and preferred stockholders of the corporation as to both income and assets for the principal and interest due to the bondholder.

**Credit and Interest Rate Risk**

Fixed-income securities, such as bonds, generally are subject to two primary types of risk: credit risk and interest rate risk. Credit risk refers to the possibility that the issuer or guarantor of a security, or counterparty to a transaction, will be unable or unwilling or perceived to be unable or unwilling to make interest payments and/or repay the principal on its debt or otherwise honor its obligations, including the risk of default. The risk of defaults across issuers, guarantors and/or counterparties increases in adverse market and economic conditions, and the degree of credit risk depends on the financial condition of the issuer, guarantor or counterparty and terms of the obligation. Credit ratings may not be an accurate assessment of financial condition, volatility, liquidity or credit risk, as the ratings do not evaluate market risks or necessarily reflect the issuer's, guarantor's or counterparty's current financial condition or the volatility or liquidity of the security. 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, guarantor or counterparty, or the market's perception of the creditworthiness of an instrument or issuer, guarantor or counterparty, can have a rapid, adverse effect on the instrument's value and 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. The Fund may also be subject to credit spread risk, which is the risk that economic and market conditions, or any actual or perceived credit deterioration, may lead to an increase in credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of an issuer's securities.

Interest rate risk refers to fluctuations (such as a decline) in the value of (or yield or income generated by) a fixed-income or other debt security resulting from changes in the general level of interest rates. A wide variety of market and economic factors can cause interest rates to rise or fall, including central bank monetary policy, rising inflation, disinflation or deflation, and changes in general economic conditions. 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 but the yield or income from new issuances of fixed-income securities generally decreases. To the extent the Fund invests in variable and floating rate securities, although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of these securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Duration measures the time-weighted expected cash flows of a fixed-income security. Securities with longer durations will generally be more sensitive to changes in interest rates than securities with shorter durations. Thus, the Fund's susceptibility to interest rate risk will increase to the extent it has a longer average portfolio duration. The proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate or on other less advantageous terms during a declining interest rate environment. In a rising interest rate environment, the duration of fixed-income securities may be extended, thus potentially reducing income and increasing interest rate 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, which may occur at any time based on a range of factors and may be sudden, frequent and significant. For example, during periods when interest rates are low, 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 or pay Fund expenses out of current income. Monetary policies, and market interest rates, are subject to change at any time and potentially frequently based on a variety of market and economic conditions. It is difficult to accurately predict the pace at which the Federal Reserve Board will change interest rates, or the timing, frequency or magnitude of such changes. The impact on fixed income and other debt instruments and market conditions from interest rate changes, regardless of the cause, could be significant and could adversely affect the Fund and its investments.

Low or high interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates could have unpredictable effects on markets and may expose debt and related markets to heightened volatility and may detract from Fund performance to the extent the Fund is exposed to such interest rates and/or volatility.

Governmental authorities and regulators may enact significant fiscal and monetary policy changes, including providing direct capital infusions into companies, creating new monetary programs and changing interest rates considerably. These actions present

**16**

[Back to **Table of Contents**](#TOC_16872)

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

heightened risks to debt instruments, and such risks could be even further heightened if these actions are unexpectedly or suddenly reversed or are ineffective in achieving their desired outcomes.

**Loans of Portfolio Securities**

The Fund may lend its portfolio securities to brokers, dealers, banks and other institutional investors. By lending its portfolio securities, the Fund attempts to increase its net investment income through the receipt of interest on the cash collateral with respect to the loan or fees received from the borrower in connection with the loan. Any gain or loss in the market price of the securities loaned that might occur during the term of the loan would be for the account of the Fund. The Fund employs an agent to implement the securities lending program and the agent receives a fee from the Fund for its services. The Fund will not lend more than 33⅓% of the value of its total assets.

The Fund may lend its portfolio securities so long as the terms, structure and the aggregate amount of such loans are not inconsistent with the 1940 Act or the rules and regulations or interpretations of the SEC thereunder, which currently require that (i) the borrower pledge and maintain with the Fund collateral consisting of liquid, unencumbered assets having a value not less than 100% of the value of the securities loaned; (ii) the borrower adds to such collateral whenever the price of the securities loaned rises (i.e., the borrower "marks-to-market" on a daily basis); (iii) the loan be made subject to termination by the Fund at any time; and (iv) the Fund receives a reasonable return on the loan (which may include the Fund investing any cash collateral in interest bearing short-term investments), any distributions on the loaned securities and any increase in their market value. In addition, voting rights may pass with the loaned securities, but the Fund will retain the right to call any security in anticipation of a vote that the Adviser deems material to the security on loan.

Loans of securities involve a risk that the borrower may fail to return the securities or may fail to maintain the proper amount of collateral, which may result in a loss of money by the Fund. There may be risks of delay and costs involved in recovery of securities or even loss of rights in the collateral should the borrower of the securities fail financially. These delays and costs could be greater for foreign securities. However, loans will be made only to borrowers deemed by the Adviser to be creditworthy and when, in the judgment of the Adviser, the income that can be earned from such securities loans justifies the attendant risk. All relevant facts and circumstances, including the creditworthiness of the broker, dealer, bank or institution, will be considered in making decisions with respect to the lending of securities, subject to review by the Trust's Board of Trustees. The Fund also bears the risk that the reinvestment of collateral will result in a principal loss. Finally, there is the risk that the price of the securities will increase while they are on loan and the collateral will not be adequate to cover their 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 (i.e., when a borrower pays back the principal of a debt obligation earlier than expected). 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, subject to heightened credit risk and the market for such securities is typically smaller and less liquid than other asset-backed securities.

The Fund may invest in other asset-backed or similarly structured securities, such as collateralized debt obligations ("CDOs"), collateralized bond obligations ("CBOs"), and collateralized loan obligations ("CLOs"). These investments are subject to many of the same risks as other forms of asset-backed securities, including interest rate risk, credit risk and default risk, and are also subject to additional risks, including but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization; (iii) the Fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by the Fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced "fire sale" liquidation due to technical defaults such as coverage test failures; and (viii) the CDO's manager may perform poorly. Investments in CDOs, CBOs and CLOs are also subject to risks particular to their respective asset class and structure.

For example, because CLOs are backed primarily by commercial loans, CLOs also bear many of the same risks as investing in loans directly. However, in addition to the risks associated with investing in commercial loans, the complex structure and highly leveraged nature of a CLO poses additional risks. CLOs may experience substantial losses attributable to loan defaults or trading losses. Such losses on the underlying assets are borne first by the holders of subordinate tranches. In addition, the Fund's investments in CLOs may decrease in market value when the CLO's assets experience loan defaults or credit impairment, losses that exceed the most subordinate tranches, or market anticipation of loan defaults and investor aversion to CLO securities as a class. CDOs are structured similarly to CLOs and bear many of the same risks as CLOs as well as additional risks because they are backed by pools of assets other than commercial loans, including securities (such as other asset-backed securities), synthetic instruments or bonds, and may be highly leveraged. Like CLOs, losses incurred by a CDO are borne first by holders of the most subordinate tranches. Accordingly, the risks of CDOs depend largely on the type of underlying collateral and the tranche of CDOs in which the Fund invests. Moreover, CDOs that obtain their exposure through synthetic investments are exposed to risks associated with derivative instruments.

**Collateralized Loan Obligations**

A CLO is an asset-backed security typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. The key feature of the CLO structure is the prioritization of the cash flows from a pool of debt securities among the several classes or tranches of CLO holders, thereby creating a series of obligations with varying rates and maturities appealing to a wide range of investors. The Fund and other investors in CLOs ultimately bear the credit and interest rate risks of the underlying collateral.

CLOs issue classes or "tranches" that offer various maturity, risk and yield characteristics. Tranches are categorized as senior, mezzanine and subordinated/equity, according to their degree of risk. The risks of an investment in a CLO depend largely on the type of the collateral securities and the class or tranche of the instrument in which the Fund invests. To the extent that the Fund invests in tranches of CLOs that are rated below investment grade, the risks of investing in CLOs will be greater. Below investment grade securities may be subject to additional risks, including those associated with high yield securities. In addition, to the extent that the Fund invests in unrated CLO tranches, the Fund's ability to achieve its investment objective will be more dependent on the Adviser's credit analysis than would be the case if the Fund were to invest in rated CLO tranches.

Interest on a CLO may be paid in kind or deferred and capitalized (paid in the form of obligations of the same type rather than cash), which involves continued exposure to default risk with respect to such payments.

In the event of sufficient early prepayments on such debt instruments, the class or series of CLO first to mature generally will be retired prior to maturity. Therefore, although in most cases the issuer of CLOs will not supply additional collateral in the event of such prepayments, there will be sufficient collateral to secure their priority with respect to other CLO tranches that remain outstanding. If there are defaults or the relevant collateral otherwise underperforms, scheduled payments to senior tranches of the CLOs take precedence over those of mezzanine tranches and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. Because it is partially protected from defaults, a senior tranche of a CLO typically has higher credit ratings and lower yields than its underlying collateral and may be rated investment grade. However, it is possible that a senior tranche of a CLO could experience losses, particularly in stressed market conditions, due to defaults, downgrades of the underlying collateral by rating agencies, forced liquidation of the collateral pool, increased sensitivity to defaults due to collateral default, market anticipation of defaults and investor aversion to CLO securities as an asset class. If a CLO triggers an event of default as a result of failing to make payments when due or for other reasons, the CLO would be subject to the possibility of liquidation, which could result in full loss of value to the CLO equity or junior debt investors.

The underlying assets (e.g., loans) are subject to prepayments which shorten the securities' weighted average maturity and may lower their return. If the credit support or enhancement is exhausted, losses or delays in payment may result if the required payments of principal and interest are not made. The value of these securities also may change because of changes in market value, which may be caused by, among other things, changes in the market's perception of the creditworthiness of the servicing agent for the pool, the originator of the pool, or the financial institution or fund providing the credit support or enhancement.

CLOs, and their underlying loan obligations, are typically not registered for sale to the public and therefore are subject to certain restrictions on transfer and sale, potentially making them less liquid than other types of securities. Additionally, when the Fund purchases a newly issued CLO security in the primary market (rather than from the secondary market), there often may be a delayed settlement period during which the liquidity of the CLO may be further reduced. As a result, the proceeds from the sale of CLO securities may not be readily available to meet the Fund's redemption or other obligations and the Fund may be unable to acquire or dispose of the securities at a price and time the Fund deems advantageous. There is no guarantee that an active secondary market will exist or be maintained for any given CLO.

CLOs in which the Fund invests may be managed by investment advisers not affiliated with the Adviser. CLO managers are responsible for selecting, managing and replacing the underlying bank loans within a CLO. CLO managers may have limited operating histories, may be subject to conflicts of interests, including managing the assets of other clients or other investment

vehicles, or receiving fees that incentivize maximizing the yield, and indirectly the risk, of a CLO. Adverse developments with respect to a CLO manager, such as personnel and resource constraints, regulatory issues or other developments that may impact the ability and/or performance of the CLO manager, may adversely impact the performance of the CLO securities in which the Fund invests. In addition, the Fund will indirectly bear any management fees and expenses incurred by a CLO.

**Mortgage-Backed Securities**

Mortgage-backed 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 (i.e., when a borrower pays back the principal of a debt obligation earlier than expected). As a result, it may not be possible to determine in advance the actual maturity date or average life of a mortgage-backed 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-backed 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-backed securities and, therefore, to assess the volatility risk of that portfolio.

The Fund may invest in mortgage-backed 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-backed 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-backed securities purchased by the Fund, such as those issued by the Federal National Mortgage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation ("Freddie Mac"), 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-backed 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.

Non-agency 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 or to sell. Non-agency 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 non-agency 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.

*Collateralized Mortgage Obligations.* 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 relative to other tranches. 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.

*Stripped Mortgage-Backed Securities.* Stripped mortgage-backed securities ("SMBS") are derivative multi-class mortgage-backed securities. SMBS may be issued by agencies or instrumentalities of the U.S. Government, or by private originators. A common type of SMBS will have one class receiving some of the interest and most of the principal from the mortgage assets, while the other class receives most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest (the interest only or "IO" class), while the other class will receive all of the principal (the principal-only or "PO" class). Investments in each class of SMBS are extremely sensitive to changes in interest rates. IOs tend to decrease in value substantially if interest rates decline and prepayment rates become more rapid. POs tend to decrease in value substantially if interest rates increase and the rate of prepayment decreases. If the Fund invests in SMBS and interest rates move in a manner not anticipated by management, it is possible that the Fund could lose all or substantially all of its investment.

*Commercial Mortgage-Backed Securities.* 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, among other risks. 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).

The values of, and income generated by, CMBS may be adversely affected by changing interest rates, tightening lending standards, and other developments impacting the commercial real estate market, such as population shifts and other demographic changes, increasing vacancies (potentially for extended periods) and reduced demand for commercial and office space as well as maintenance or tenant improvement costs and costs to convert properties for other uses. These developments could result from, among other things, changing tastes and preferences (such as remote work arrangements) as well as cultural, technological, global or local economic and market developments. In addition, changing interest rate environments and associated changes in lending standards and higher refinancing rates may adversely affect the commercial real estate and CMBS markets. The occurrence of any of the foregoing or similar developments would likely increase default risk for the properties and loans underlying these investments as well as impact the value of, and income generated by, these investments. These developments could also result in reduced liquidity for CMBS.

**Equity Securities**

Equity securities may include common and preferred stocks, convertible securities and equity-linked securities, rights and warrants to purchase common stocks, depositary receipts, shares of investment companies, limited partnership interests and other specialty securities having equity features. Many factors affect the value of equity securities, including earnings, earnings forecasts, corporate events and factors impacting the issuer's financial condition, sector, industry and the market generally, such as labor shortages or an increase in production costs and competitive conditions within an industry. The value of the equity securities held by the Fund may fluctuate rapidly and unpredictably, and these fluctuations may be frequent and significant. In addition, the Fund cannot accurately predict the income it might receive from equity securities because issuers generally have discretion as to the payment of dividends or distributions, and the common stock of an issuer in the Fund's portfolio may decline in price if, for example, the issuer fails to make anticipated dividend payments because of a decline in the issuer's financial condition. The Fund may invest in equity securities that are publicly traded on securities exchanges or over-the-counter ("OTC") or in equity securities that are not publicly traded. Equity securities are subject to the risk that stock prices in general (or in particular, the prices of the types of securities in which the Fund invests) may decline over short or extended periods of time. Equity securities that are not publicly traded may be more difficult to value or sell and their value may fluctuate more dramatically than publicly traded equity securities. The prices of convertible securities are affected by changes similar to those of equity and fixed-income securities.

The value of equity securities and related instruments decline in response to perceived or actual adverse changes in the economy, economic outlook or the financial markets; deterioration in investor sentiment; inflation, interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer- and sector-specific considerations; unexpected trading activity among retail investors; and other factors. Market conditions affect certain types of equity securities to a greater extent than other types of equity securities. In addition, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer. If the stock market declines, the value of the Fund's equity securities will also likely decline, which will result in a decrease in the value of your investment in the Fund. Although stock prices can rebound, there is no assurance that values of the Fund's equity securities will return to previous levels.

U.S. and foreign stock markets, and equity securities of individual issuers, have experienced periods of substantial price volatility in the past and it is possible that they will do so again in the future. During periods when equity securities experience heightened volatility, such as during periods of market, economic or financial uncertainty or distress, the Fund's investments in equity securities are subject to heightened risks. In addition, the price of equity securities of an issuer may be particularly sensitive to general movements in the stock market and a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund.

**Convertible Securities**

A convertible security is a bond, debenture, note, preferred stock, right, warrant or other security that may be converted into or exchanged for a prescribed amount of common stock or other security of the same or a different issuer or into cash within a particular period of time at a specified price or formula. A convertible security generally entitles the holder to receive interest paid or accrued on debt securities or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities generally have characteristics similar to both debt and equity securities. The prices of convertible securities are affected by changes similar to those of equity and fixed-income securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities. Convertible securities ordinarily provide a stream of income with generally higher yields than those of common stock of the same or similar issuers. Convertible securities generally rank senior to common stock in a corporation's capital structure but are usually subordinated to other comparable nonconvertible fixed-income securities in such capital structure. Convertible securities generally do not participate directly in any dividend increases or decreases of the underlying securities although the market prices of convertible securities may be affected by any dividend changes or other changes in the underlying securities.

**U.S. Treasury and 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 Federal National Mortgage Association or Federal Home Loan Mortgage Corporation, 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. U.S. government securities are also subject to interest rate risks and can exhibit price fluctuations resulting from increases or decreases in interest rates. The U.S. government securities in which the Fund may invest may pay fixed, floating, variable or adjustable interest rates. For more information about interest rate risks associated with the Fund's investments in U.S. government securities, see "Credit and Interest Rate Risk".

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 and may differ in their interest rates, maturities and times of issuance. 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. Securities issued by the U.S. Treasury and agencies and instrumentalities of the U.S. government generally provide a lower current return than obligations of other issuers. The Fund may also 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 Fannie Mae, Freddie Mac and the Federal Home Loan Banks. 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. With respect to U.S. government securities 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, and therefore these U.S. government securities involve greater credit risk than of U.S. government securities backed by the full faith and credit of the U.S. government. 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. In addition, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could increase the risk that the U.S. government may default on payments on U.S. government securities and may cause the credit rating of the U.S. government to be downgraded. Any uncertainty regarding the ability of the United States to repay its debt obligations, and any default by the U.S. government, would have a negative impact on the Fund's investments in U.S. government securities. U.S. government securities generally have a lower return than other obligations.

**Loans**

Loans may be primary, direct investments or investments in loan assignments or participation interests. A loan assignment represents a portion or the entirety of a loan and a portion or the entirety of a position previously attributable to a different lender. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement and has the same rights and obligations as the assigning investor. However, assignments through private negotiations may cause the purchaser of an assignment to have different and more limited rights than those held by the assigning investor. Loan participation interests are interests issued by a lender or other entity and represent a fractional interest in a loan. The Fund typically will have a contractual relationship only with the financial institution that issued the participation interest. As a result, the Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the financial institution and only upon receipt by such entity of such payments from the borrower. In connection with purchasing a participation interest, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other investors through set-off against the borrower and the Fund may not directly benefit from the collateral supporting the loan in which it has purchased the participation interest. As a result, the Fund would generally assume the credit risk of both the borrower and the financial institution issuing the participation interest. In the event of the insolvency of the entity issuing a participation interest, the Fund may be treated as a general creditor of such entity. Most loans are rated below investment grade or, if unrated, are of similar credit quality. Certain loans are illiquid, meaning the Fund may be unable to sell them at an advantageous time or price. Illiquid securities are also difficult to value.

Loan investments may be made at par or at a discount or premium to par. The interest payable on a loan may be fixed or floating rate, and paid in cash or in-kind. In connection with transactions in loans, the Fund may be subject to facility or other fees. Loans may be secured by specific collateral or other assets of the borrower, guaranteed by a third party, unsecured or subordinated. During the term of a loan, the value of any collateral securing the loan may decline in value, causing the loan to be under collateralized. Collateral may consist of assets that may not be readily liquidated, and there is no assurance that the collateral will be available and liquidation of such assets would satisfy fully a borrower's obligations under the loan. In addition, if a loan is foreclosed, the Fund

could become part owner of the collateral and would bear the costs and liabilities associated with owning and disposing of such collateral.

Certain loans ("senior loans") hold a senior position in the capital structure of a business entity, are typically secured with specific collateral and have a claim on the assets and/or stock of the borrower that is senior to that held by subordinated debtholders and stockholders of the borrower. Junior loans may be secured or unsecured subordinated loans, second lien loans and subordinated bridge loans, and typically carry greater risks. For example, second lien loans are lower in priority to senior loans, but have seniority in a company's capital structure to other liabilities and a company is required to pay down these second lien loans prior to other lower-ranked claims on their assets. Floating-rate loans typically have rates of interest which are re-determined daily, monthly, quarterly or semi-annually by reference to a base lending rate, plus a premium. Floating-rate loans held by the Fund typically have a dollar-weighted average period until the next interest rate adjustment of approximately 90 days or less.

A lender's repayment and other rights primarily are determined by governing loan, assignment or participation documents, which (among other things) typically establish the priority of payment on the loan relative to other indebtedness and obligations of the borrower. A borrower typically is required to comply with certain covenants contained in a loan agreement between the borrower and the holders of the loan. Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower's operations or assets and by providing certain information and consent rights to lenders. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness of the issuer, and the nature of the collateral securing the loan. Loans also known as "covenant lite" loans may contain fewer covenants that restrict activities of the borrower or that might enable the Fund to, among other things, proactively enforce financial covenants or prevent undesired actions by the borrower. As a result, "covenant lite" loans may provide the borrower with more flexibility to take actions that may otherwise be limited or prohibited under similar loan obligations that are not covenant lite or that may be detrimental to the loan holders and provide fewer investor protections in the event covenants are breached. The Fund may experience relatively greater realized or unrealized losses or delays and expense in enforcing its rights with respect to loans with fewer restrictive covenants than its holdings of loans or securities with more traditional financial covenants. In addition, the Fund may receive less or less frequent financial reporting from a borrower under a "covenant lite" loan or obligation, which may result in more limited access to financial information, difficulty evaluating the borrower's financial performance over time and delays in exercising rights and remedies. Many loans and similar debt obligations may not feature traditional financial maintenance covenants.

Loans to entities located outside of the U.S. may have substantially different lender protections and covenants as compared to loans to U.S. entities and generally involve greater and additional risks. In the event of bankruptcy, applicable law may impact a lender's ability to enforce its rights. Bankruptcy laws in foreign jurisdictions, including emerging markets, may differ significantly from U.S. bankruptcy law and the Fund's rights with respect to a loan governed by the laws of a foreign jurisdiction may be more limited.

Loans may be originated by a lending agent, such as a financial institution or other entity, on behalf of a group or "syndicate" of loan investors (the "Loan Investors"). In such a case, the agent administers the terms of the loan agreement and is responsible for the collection of principal, and interest payments from the borrower and the apportionment of these payments to the Loan Investors. Failure by the agent to fulfill its obligations may delay or adversely affect receipt of payment by the Fund. Furthermore, unless under the terms of a loan agreement or participation (as applicable) the Fund has direct recourse against the borrower, the Fund must rely on the agent and the other Loan Investors to pursue appropriate remedies against the borrower.

Although the overall size and number of participants in the market for many loans has grown over the past decade, such loans continue to trade in a private, unregulated inter-dealer or inter-bank secondary market and the amount of available public information about loans may be less extensive than that available for registered or exchange listed securities. Liquidity and valuation risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed-income instruments or equity securities. With limited exceptions, the Adviser will seek to take steps intended to ensure that it does not receive material nonpublic information about the issuers of loans that also issue publicly traded securities. Therefore, the Adviser may have less information than other investors about certain of the loans in which it seeks to invest. Purchases and sales of loans are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may (i) impede the Fund's ability to buy or sell loans, (ii) negatively impact the transaction price, (iii) impact the counterparty and/or credit risks borne by the Fund, (iv) impede the Fund's ability to timely vote or otherwise act with respect to loans, (v) expose the Fund to adverse tax or regulatory consequences and/or (vi) result in delayed settlement of loan transactions. It may take longer than seven days for a transaction in loans to settle, which may impact the Fund's process and ability to meet redemptions. This is partly due to the nature or manner in which loans trade and the contractual restrictions noted above, which require a written assignment agreement and various ancillary documents for each transfer, and frequently require discretionary consents from both the borrower and the administrative agent. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund's redemption or other obligations for a period after the sale of the loans and, as a result, the Fund may have to hold additional cash, sell other investments or engage in borrowing transactions, such as borrowing from a credit facility, if necessary to raise cash to meet its obligations.

Assignments of loans through private negotiations may cause the purchaser of an assignment to have different and more limited rights than those held by the assigning investor. In connection with purchasing a participation interest, the Fund generally will have

**23**

------

[Back to **Table of Contents**](#TOC_16872)

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

no right to enforce compliance by the borrower with the terms of the loan agreement. In the event the borrower defaults, the Fund may not directly benefit from the collateral supporting the loan (if any) in which it has purchased the participation interest. As a result, the Fund would generally assume the credit risk of both the borrower and the financial institution issuing the participation interest, subjecting the Fund to additional credit risk (including the creditworthiness of the agent lender), and the Fund may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower. No active trading market may exist for certain loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a loan and which may make it difficult to value the loan. To the extent that a secondary market does exist for certain loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods.

In addition to the risks generally associated with debt instruments, such as credit, market, interest rate and liquidity risks, loans are also subject to the risk that the value of any collateral securing a loan may decline, be unavailable or insufficient to meet the obligations of the borrower or be difficult to liquidate. The specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan's value. The Fund's access to collateral may be limited by bankruptcy, other insolvency laws or by the type of loan the Fund has purchased. For example, if the Fund purchases a participation instead of an assignment, it would not have direct access to collateral of the borrower. As a result, a floating-rate loan may not be fully collateralized and can decline significantly in value. Additionally, collateral on loan instruments may not be readily liquidated, and there is no assurance that the liquidation of such assets will satisfy a borrower's obligations under the investment.

Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate a loan to presently existing or future indebtedness of the borrower, or take other action detrimental to the holders of a loan including, in certain circumstances, invalidating a loan or causing interest previously paid to be refunded to the borrower. Any such actions by a court could negatively affect the Fund's performance. Loans that are secured and senior to other debtholders of a borrower tend to have more favorable loss recovery rates as compared to more junior types of below investment grade debt obligations. Due to their lower place in the borrower's capital structure and, in some cases, their unsecured status, junior loans involve a higher degree of overall risk than senior loans of the same borrower.

Investing in loans involves the risk of default in the payment of interest or principal by the borrower or other party obligated to repay the loan, which would result in a reduction of income to the Fund or in other losses and a potential decrease in the Fund's NAV. The risk of default will increase in the event of an economic downturn or a substantial increase in interest rates. In the event of insolvency of the borrower or other obligated party, the Fund may be treated as a general creditor of such entity unless it has rights that are senior to that of other creditors or secured by specific collateral or assets of the borrower. Fixed rate loans are also subject to the risk that their value will decline in a rising interest rate environment. This risk is mitigated for floating-rate loans, where the interest rate payable on the loan resets periodically by reference to a base lending rate.

Loans that are rated below investment grade are also subject to the risks of other below investment grade securities. Because loans in which the Fund may invest could rank lower in priority of payment to senior loans, they present greater degree of investment risk due to the fact that the cash flow or other property of the borrower securing the loan may be insufficient to meet scheduled payments after meeting the senior secured payment obligations of the borrower. These loans may also exhibit greater price volatility as well.

U.S. federal securities laws afford certain protections against fraud and misrepresentation in connection with the offering or sale of a security, as well as against manipulation of trading markets for securities. The typical practice of a lender in relying exclusively or primarily on reports from the borrower may involve the risk of fraud, misrepresentation, or market manipulation by the borrower. It is unclear whether U.S. federal securities laws protections are available to an investment in a loan. In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. However, contractual provisions in the loan documents may offer some protections, and lenders may also avail themselves of common-law fraud protections under applicable state law.

**Covenant Lite Investments**

Some of the loans or other obligations in which the Fund may invest or obtain exposure to may be "covenant lite" loans or other obligations. Certain financial institutions may define "covenant lite" loans or securities differently. Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower's operations or assets and by providing certain information and consent rights to lenders. Covenant lite loans or securities, which have varied terms and conditions, may contain fewer or no restrictive covenants compared to other loans that might enable the Fund to, among other things, proactively enforce financial covenants or prevent undesired actions by the borrower. As a result, covenant lite loans generally carry greater risks because they allow borrowers to exercise more flexibility with respect to certain activities that may otherwise be limited or prohibited under similar loan obligations that are not covenant lite. In addition, the Fund may receive less or less frequent financial reporting from a borrower under a covenant-lite obligation, which may result in more limited access to financial information, difficulty evaluating the borrower's financial performance over time and delays in exercising rights and remedies in the event of a significant financial decline. The Fund may experience relatively greater difficulty or delays in enforcing its rights on its holdings of certain covenant lite loans and other similar obligations than its holdings of loans or securities with more traditional financial covenants, which may result in losses to the Fund. Many loans and similar debt obligations may not feature

traditional financial maintenance covenants, which are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower's operations or assets and by providing certain information and consent rights to lenders.

**Repurchase Agreements**

Repurchase agreements are transactions in which the Fund purchases a security or basket of securities and simultaneously commits to resell that security or basket to the seller (a bank, broker or dealer) at a mutually agreed-upon date and price. The resale price reflects the purchase price plus an agreed-upon market rate of interest which is unrelated to the coupon rate or date of maturity of the purchased security. The term of these agreements usually ranges from overnight to one week, and never exceeds one year. Repurchase agreements with a term of over seven days are considered illiquid.

In these transactions, the Fund receives securities that have a market value at least equal to the purchase price (including accrued interest) of the repurchase agreement, and this value is maintained during the term of the agreement. These securities are held by the Fund's custodian or an approved third-party for the benefit of the Fund until repurchased. Repurchase agreements permit the Fund to remain fully invested while retaining overnight flexibility to pursue investments of a longer-term nature. If the seller defaults and the value of the repurchased securities declines, the Fund might incur a loss. If bankruptcy proceedings are commenced with respect to the seller, the Fund's realization upon the collateral may be delayed.

While repurchase agreements involve certain risks not associated with direct investments in debt securities, the Fund follows procedures approved by the Trustees that are designed to minimize such risks. These procedures include effecting repurchase transactions only with large, well-capitalized and well-established financial institutions whose financial condition will be continually monitored by the Adviser. In addition, as described above, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund will seek to liquidate such collateral. However, the exercising of the Fund's right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss.

The Fund's investments in repurchase agreements may at times be substantial when, for example, in the view of the Fund's Adviser, liquidity or other conditions warrant.

**Reverse Repurchase Agreements**

The Fund may also use reverse repurchase agreements as part of its investment strategies. Under a reverse repurchase agreement, the Fund sells a security and promises to repurchase that security at an agreed-upon future date and price. The price paid to repurchase the security reflects interest accrued during the term of the agreement. Reverse repurchase agreements may be entered into for, among other things, obtaining leverage, facilitating short-term liquidity or when the Adviser expects that the interest income to be earned from the investment of the transaction proceeds will be greater than the related interest expense. Reverse repurchase agreements may be viewed as a speculative form of borrowing called leveraging. Furthermore, reverse repurchase agreements involve the risks that (i) the interest income earned in the investment of the proceeds will be less than the interest expense, (ii) the market value of the securities retained in lieu of sale by the Fund may decline below the price of the securities the Fund has sold but is obligated to repurchase, (iii) the market value of the securities sold will decline below the price at which the Fund is required to repurchase them and (iv) the securities will not be returned to the Fund.

In addition, the use of leverage may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations. Leverage, including borrowing, may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund's portfolio securities. All forms of borrowing are limited in the aggregate and may not exceed 33⅓% of the Fund's total assets, except as permitted by law or SEC requirements.

**When-Issued Securities, Delayed Delivery Securities, TBAs and Forward Commitments**

The Fund may purchase or sell securities that it is entitled to receive on a when-issued basis. The Fund may also purchase or sell securities on a delayed delivery basis or through a forward commitment (including on a TBA (to be announced) basis). These transactions involve the purchase or sale of securities by the Fund at an established price with payment and delivery taking place in the future. The Fund enters into these transactions to obtain what is considered an advantageous price to the Fund at the time of entering into the transaction. Such transactions entered into 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. For example, the Fund may invest in TBAs, which settle on a delayed delivery basis. In a TBA transaction, the seller agrees to deliver the MBS for an agreed upon price on an agreed upon future date, but makes no guarantee as to which or how many securities are to be delivered. Accordingly, the Fund's investments in TBAs are subject to risks such as failure of the counterparty to perform its obligation to deliver the security, the characteristics of a security delivered to the Fund may be less favorable than expected and the security the Fund buys will lose value prior to its delivery. Investments in TBAs may give rise to a form of leverage. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged and may increase the impact that gains (losses) have on the Fund. Further, TBAs may increase the Fund's portfolio turnover rate. FINRA rules include mandatory margin requirements that will require the Fund to post collateral in

connection with its TBA transactions, which could increase the cost of TBA transactions to the Fund and impose added operational complexity.

The Fund's purchase of other securities on a when-issued, delayed delivery or through a forward commitment basis are subject to similar risks, including counterparty risk and that the value of securities in these transactions on the delivery date may be less than the price paid by the Fund to purchase the securities. In addition, there can be no assurance that a security purchased on a when-issued basis will be issued. When the Fund has sold a security on a when-issued, delayed delivery, or forward commitment basis, the Fund does not benefit if the value of the security appreciates above the sale price during the commitment period and the Fund is subject to failure of the counterparty to pay for the securities.

**Short Sales**

A short sale is a transaction in which the Fund sells securities that it owns or has the right to acquire at no added cost (i.e., "against the box") or does not own (but has borrowed) in anticipation of a decline in the market price of the securities. To deliver the securities to the buyer, the Fund arranges through a broker to borrow the securities and, in so doing, the Fund becomes obligated to replace the securities borrowed at their market price at the time of replacement. When selling short, the Fund intends to replace the securities at a lower price and therefore, profit from the difference between the cost to replace the securities and the proceeds received from the sale of the securities. When the Fund makes a short sale, the proceeds it receives from the sale will be held on behalf of a broker until the Fund replaces the borrowed securities. The Fund may have to pay a premium to borrow the securities and must pay any dividends or interest payable on the securities until they are replaced.

The Fund's obligation to replace the securities borrowed in connection with a short sale will be secured by collateral deposited with the broker that consists of cash or other liquid securities. Short sales by the Fund involve certain risks and special considerations. If the Adviser incorrectly predicts that the price of the borrowed security will decline, the Fund will have to replace the securities with securities with a greater value than the amount received from the sale. As a result, losses from short sales differ from losses that could be incurred from a purchase of a security, because losses from short sales may be unlimited, whereas losses from purchases can equal only the total amount invested.

**Money Market Instruments**

Money market instruments may be adversely affected by market and economic events, such as a change 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 or an issuer. These instruments may be subject to federal income, state income and/or other taxes. Instead of investing in money market instruments directly, the Fund may invest money market funds, including those advised by the Adviser or its affiliates. These instruments may be adversely affected by changes to interest rates, which may be sudden and significant. 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.

**Non-Diversification Risk**

Eaton Vance CLO Investment Grade Income ETF is non-diversified, which means that the Fund may invest a greater percentage of its assets in a smaller number of issuers than diversified funds. A fund that is classified as non-diversified may be more susceptible to an adverse event affecting a single issuer or portfolio investment than a diversified portfolio and a decline in the value of issuer's securities or that portfolio that investment may cause the Fund's overall value to decline to a greater degree than a diversified portfolio.

**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.

**Distressed and Defaulted Securities**

Distressed and defaulted securities are speculative and involve substantial risks in addition to the risks of investing in high yield securities. The Fund will generally not receive interest payments on the distressed securities and the repayment of principal may also be at risk. These securities may present a substantial risk of default or may be in default at the time of investment. The repayment of defaulted securities is also subject to significant uncertainties. The Fund may incur substantial expenses in seeking recovery upon a default in the payment of principal of or interest on its portfolio holdings. If the portfolio company is forced to reorganize or liquidate, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

**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 interest 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. Municipal 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. Revenue bonds 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.

Municipal 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. These factors, which may also impact other municipal obligations, include, among others, changing demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments, as well as reduced demand for properties, revenues or goods. 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 or issuers of municipal securities have had significant financial problems recently, and these and other municipalities or issuers of municipal securities could, potentially, continue to experience significant financial problems resulting from lower tax or other 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 and issuers of municipal securities may include, among other developments, 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, recent public health emergencies have 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 recent public health emergencies have caused disruptions in business activities. These and other effects of recent public health emergencies, 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, liquidity 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, similar projects or particular states or geographic regions may particularly affect the overall municipal securities market. In addition, changes in the financial condition of an individual municipal issuer can

**27**

[Back to **Table of Contents**](#TOC_16872)

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

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. Moreover, as a result of various economic, market and other factors, there could be reduced tax or other revenue available to issuers of municipal obligations and, in turn, increased budgetary and financial pressure on municipalities and other issuers of municipal obligations, which could adversely impact the risks associated with municipal obligations of such issuer. Asa result, the Fund's investments in municipal obligations may be subject to heightened risks relating to the occurrence of such developments.

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. In addition, interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from the federal alternative minimum 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.

**State and Municipal Project-Specific Risk**

The Eaton Vance High Income Municipal ETF may invest in municipal securities that are related in such a way that an economic, business, or political development or change affecting one such security would likewise affect the other municipal securities. For example, the Fund may invest 25% or more of its total assets in certain types of municipal obligations (such as general obligations, municipal leases, principal only municipal investments, revenue bonds and industrial development bonds) and in one or more states, territories and economic sectors (such as housing, hospitals, healthcare facilities or utilities). Because the Fund may invest a significant portion of its assets in obligations issued in one or more states and/or U.S. territories and in certain types of municipal or other obligations and/or in certain sectors, the value of Fund shares may be affected by events that adversely affect that state, U.S. territory, sector or type of obligation and may fluctuate more than that of a fund that invests more broadly. These developments or changes may include, among other things, legislative developments involving the financing of projects, judicial decisions regarding the validity of the projects or the means of financing such projects, shortages or price increases of materials needed for the project or declining needs for the projects as well as other developments that may adversely affect municipalities and other issuers of municipal securities located within the same state, such as natural disasters, health emergencies, and adverse economic, political or social environments. General obligation bonds issued by municipalities can be adversely affected by, among other things, economic downturns and other developments that result in a decline in tax revenues. Revenue bonds can be adversely affected by, among other things, the negative economic performance or viability of the facility or revenue source.

**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. These risks may be intensified for the Fund's investments in securities of issuers located in emerging market or developing countries.

**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 generally offer a higher yield than higher rated securities (including those of a similar maturity), but they carry a greater degree of risk, including substantial credit and default risks. High yield securities are subject to greater risk of loss (including substantial or total loss) of income and principal than higher rated securities and are considered speculative by the major credit rating agencies because of increased credit risk relative to higher rated fixed income investments. High yield securities are also subject to other increased risks, including greater sensitivity to real or perceived economic changes, increased price volatility, valuation difficulties, lack of a regular trading market and greater potential illiquidity. High yield securities are particularly susceptible to default risk during periods of adverse market, industry or economic conditions or issuer-specific developments and a high yield security may lose significant value before a default occurs. In the event of a default, the Fund may incur additional expenses to seek recovery or to negotiate new terms with a defaulting issuer.

In addition, the Fund's investments in high yield securities are subject to the risk of subordination to other creditors. Accordingly, in the event of an issuer's bankruptcy, claims of other creditors may have priority over the claims of holders of these securities, leaving

**28**

[Back to **Table of Contents**](#TOC_16872)

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

few or no assets available to repay high yield securities holders, such as the Fund. High yield securities may be issued by companies that are restructuring, are smaller and less creditworthy or are more highly leveraged or indebted than other companies or are financially distressed. This means that they typically have more difficulty making scheduled payments of principal and interest and a higher risk of non-payment. An issuer's ability to pay its debt obligations may also be reduced by financial stress, specific issuer developments or the unavailability of additional financing. Changes in the value of and income from high yield securities are typically 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 addition, high yield securities are subject to increased call risk, also known as prepayment risk, which is the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (*e.g*., declining interest rates, changes in credit spreads and improvements in the issuer's credit quality). If an issuer calls a security in which the Fund has invested, the Fund may not recoup the full amount of its initial investment (including any premiums paid) or may not realize the full anticipated earnings from the investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features.

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 or provide 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.

**Residual Interest Bonds**

The Eaton Vance High Income Municipal ETF may enter into residual interest bond transactions, which expose the Fund to leverage and greater risk than an investment in a fixed-rate municipal bond. The interest payments that the Fund receives on the residual interest bonds acquired in such transactions vary inversely with short-term interest rates, normally decreasing when short-term rates increase. The value and market for residual interest bonds are volatile and such bonds may have limited liquidity. As required by applicable accounting standards, the Fund records interest expense as a liability with respect to floating-rate notes and also records offsetting interest income in an amount equal to this expense.

**Foreign Securities**

Investing in foreign securities (including depositary receipts) involves certain special and heightened risks, which are not typically associated with investments in the securities of U.S. issuers, that can increase the chances that the Fund will lose money. Foreign issuers generally are subject to different corporate governance, 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, experience greater price movements, and may be subject to foreign withholding taxes and/or other taxes, which decreases the yield and/or return of these securities. The Fund may experience losses if the Fund's claim to recover foreign withholding taxes is not successful. In addition, the prices of foreign securities may be susceptible to influence by large traders due to the limited size of many foreign securities markets. Moreover, investments in certain foreign markets that have historically been considered stable may become more volatile and subject to increased risk due to developments and changing conditions in such markets. Also, the growing interconnectivity of global economies and financial markets has increased the probability that adverse developments and conditions in one country or region will affect the stability of economies and financial markets in other countries or regions. In some foreign countries, there is also the risk of government expropriation, excessive or confiscatory taxation, political or social instability, the imposition of currency controls or diplomatic developments that could affect the Fund's investments. 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. Securities registration, custody, and settlement may be subject to delays and legal and administrative uncertainties. If the Fund cannot settle or is delayed in settling a purchase of securities, it may miss attractive investment opportunities and experience other adverse consequences. In some non-U.S. securities markets, custody arrangements for securities provide significantly less protection than custody arrangements in U.S. securities markets, and prevailing custody and trade settlement practices (e.g., the requirement to pay for securities prior to receipt) expose the Fund to credit and other risks it does not have in the United States. In addition, in certain markets the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. The cost of investing in foreign securities, including brokerage commissions and custodial expenses, can be higher than the cost of investing in domestic securities. Foreign market trading hours, clearance and settlement procedures, and holiday schedules may also limit the Fund's ability to buy and sell securities during certain periods.

The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position. Certain foreign markets may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments (including regional and global, military or other conflicts), the imposition of economic sanctions against a particular country or countries, organizations, companies, entities and/or individuals, changes in international trading patterns, tariffs, trade barriers and other protectionist or retaliatory measures. International trade barriers or economic sanctions against foreign countries, organizations, companies, entities and/or individuals may adversely affect 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 interventions or other 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. The value of holdings traded outside the United States (and any hedging transactions in foreign currencies) will be affected by changes in currency exchange rates. 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 force the Fund to 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 and decline in value in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market, economic, political and social 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. To the extent 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 trade laws of and potential economic sanctions by 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 also 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. In addition, 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.

Even if the Fund does not have significant investments in securities affected by sanctions, sanctions or the threat of sanctions may cause volatility in regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, including through global supply chain disruptions, increased inflationary pressures, and reduced economic activity, which could have a negative effect on the Fund's performance. In addition, trade disputes and changes in tariffs may affect investor and consumer confidence and adversely affect financial markets and the broader economy, perhaps suddenly and to a significant degree. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is difficult to predict.

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

**Sovereign Debt Obligations**

The Fund may invest in debt obligations known as "sovereign debt," which are obligations of governmental issuers in emerging market or developing countries and industrialized countries. Certain emerging market or developing countries are among the largest debtors to commercial banks and foreign governments. The issuer or governmental authority that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or pay interest when due in accordance with the terms of such obligations. Uncertainty surrounding the level and sustainability of sovereign debt of certain countries has at times increased volatility in the financial markets. In addition, a number of Latin American countries are among the largest debtors of developing countries and have a long history of reliance on foreign debt. Additional factors that may influence the ability or willingness to service debt include, but are not limited to, a country's cash flow situation, the availability of sufficient foreign exchange on the date a payment is due, the relative size of its debt service burden to the economy as a whole and its government's policy towards the International Monetary Fund, the World Bank and other multilateral agencies. A country whose exports are concentrated in a few commodities or whose economy depends on certain strategic imports could be vulnerable to fluctuations in international prices of these commodities or imports. If a foreign sovereign obligor cannot generate sufficient earnings from foreign trade to service its external debt, it may need to depend on continuing loans and aid from foreign governments, commercial banks and multilateral organizations, and inflows of foreign investment. The commitment on the part of these foreign governments, multilateral organizations and others to make such disbursements may be conditioned on the government's implementation of economic reforms and/or economic performance and the timely service of its obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third-parties' commitments to lend funds, which may further impair the foreign sovereign obligor's ability or willingness to timely service its debts. In addition, there is no legal process for collecting on a sovereign debt that a government does not pay or bankruptcy proceeding by which all or part of the sovereign debt that a government entity has not repaid may be collected.

**Currency Derivatives**

Investments in currency derivatives 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. In addition, investments in currency derivatives, to the extent that they reduce the Fund's exposure to currency risks, may also reduce the Fund's ability to benefit from favorable changes in currency exchange rates. The Fund is not required to hedge any portfolio holding with the use of currency derivatives. Accordingly, Fund shareholders would bear the risk of currency fluctuations with respect to unhedged portfolio positions.

Foreign currency derivatives may involve, for example, the purchase of foreign currencies for U.S. dollars or the maintenance of short positions in foreign currencies. Foreign currency derivatives may involve the Fund agreeing to exchange an amount of a currency it does not currently own for another currency at a future date. The Fund would typically engage in such a transaction in anticipation of a decline in the value of the currency it sells relative to the currency that the Fund has contracted to receive in the exchange. 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.

The Fund may enter into foreign currency forward exchange contracts, and currency and currency index futures and options contracts for hedging and non-hedging purposes in pursuing its investment objectives. Foreign currency forward exchange contracts are transactions involving the Fund's obligation to purchase or sell a specific currency at a future date at a specified price. Foreign currency forward exchange contracts may be used by the Fund for hedging purposes to protect against uncertainty in the level of future non-U.S. currency exchange rates, such as when the Fund anticipates purchasing or selling a non-U.S. security. This technique would allow the Fund to "lock in" the U.S. dollar price of the security. Foreign currency forward exchange contracts may also be used to attempt to protect the value of the Fund's existing holdings of non-U.S. securities. Imperfect correlation may exist, however, between the Fund's non-U.S. securities holdings and the foreign currency forward exchange contracts entered into with respect to those holdings. 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. Furthermore, such transactions reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken. Currency futures contracts are similar to foreign currency forward exchange contracts, except that they are traded on an exchange and standardized as to contract size and delivery date. Most currency futures contracts call for payment or delivery in U.S. dollars. The value of a foreign currency option is dependent upon the value of the underlying foreign currency relative to the U.S. dollar. The price of the option may vary with changes in the value of either or both currencies and has no relationship to the investment merits of a foreign security. Options on foreign currencies are affected by all of those factors which influence foreign exchange rates and foreign investment generally. Unanticipated changes in currency prices may result in losses to the Fund and poorer overall performance for the Fund than if it had not entered into such contracts. 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 forward exchange contracts and currency futures and options 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 portfolio. Investing in foreign currencies 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.

**Depositary Receipts**

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

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

**Foreign Currency Forward Exchange Contracts**

In connection with their investments in foreign securities, the 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 seek to protect against uncertainty in the level of future foreign currency exchange rates or to gain or modify exposure to a particular currency. In addition, the Fund may use cross currency hedging or proxy hedging with respect to currencies in which the Fund has or expects to have portfolio or currency exposure. Cross currency and proxy hedges involve the sale of one currency against the positive exposure to a different currency and may be used for hedging purposes or to establish an active exposure to the exchange rate between any two currencies.

Investments in foreign currency forward exchange contracts may substantially change the Fund's exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the Adviser expect. 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 anticipate 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 restricted securities, which are generally subject to resale or transfer restrictions or prohibitions as a matter of contract and/or under applicable U.S. federal securities laws, including Rule 144A under the Securities Act of 1933, as amended. Restricted securities may not be listed on an exchange and may have no active trading market. Because there may be relatively few potential or interested purchasers for privately placed or restricted securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund may be unable to dispose of such securities promptly or may be able to sell privately placed securities only at disadvantageous times or prices.

There is no assurance that a liquid market will exist for restricted securities and these securities could have the effect of increasing the level of Fund illiquidity. In addition, 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, including readily available market quotations, 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. Additionally, the Fund may be unable to sell a privately placed or restricted security if the Adviser or its affiliates receive material non-public information about the security's issuer. 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 and may be unable to sell the security at all. There is typically less information

**32**

[Back to **Table of Contents**](#TOC_16872)

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

available about issuers of private placements and restricted securities and there is no assurance that the information obtained by the Adviser is reliable. In addition, private placements and restricted securities may involve a high degree of business and financial risk, which may result in substantial losses to the Fund.

**Derivatives**

The Fund may, but is not required to, use derivatives and other similar instruments for a variety of purposes, including hedging, risk management, portfolio management or to seek to earn income. Derivative instruments used by the Fund will be counted towards the Fund's exposure in the types of securities listed herein to the extent they have economic characteristics similar to such securities. A derivative is a financial instrument whose value is based, in part, on the value of an underlying asset, interest rate, index or financial instrument. Prevailing interest rates and volatility levels, among other things, also affect the value of derivative instruments. Derivatives and other similar instruments that create synthetic exposure often are subject to risks similar to those of the underlying asset or instrument and may be subject to additional risks, including imperfect correlation between the value of the derivative and the underlying asset, risks of default by the counterparty to certain transactions, magnification of losses incurred due to changes in the market value of the securities, instruments, indices or interest rates to which the derivative instrument relates, risks that the transactions may not be liquid, risks arising from margin and payment requirements, risks arising from mispricing or valuation complexity and operational and legal risks. The use of derivatives involves risks that are different from, and possibly greater than, the risks associated with other portfolio investments. Derivatives may involve the use of highly specialized instruments that require investment techniques and risk analyses different from those associated with other portfolio investments.

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

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

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

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

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

Foreign currency options contracts may be used for hedging purposes or non-hedging purposes in pursuing the Fund's investment

**33**

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

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

**Liquidity**

The Fund may make investments that are less liquid, illiquid or restricted or that may become illiquid or less liquid in response to, among other developments, overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. Illiquidity can also be caused by, among other things, a drop in overall market trading volume, an inability to find a willing buyer, or legal restrictions on the securities' resale. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. Liquidity risk may be magnified in a market where credit spread and interest rate volatility is rising and where investor redemptions from fixed-income funds may be higher than normal. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value and may be unable to sell the security at all.

Certain CLO securities may have limited liquidity in various market conditions, and in such instances will be less liquid than more senior or higher-rated CLOs. The price of CLO securities may rapidly decline if a large number of holders of the CLO securities decide to sell. The CLO market is smaller relative to other fixed-income instrument markets. Historic liquidity measures of CLOs may or may not be predictive of the liquidity of CLOs in the future. During adverse market conditions, there may be instances in which the market for trading CLOs becomes thin, or in extreme circumstances, particularly with respect to subordinate or lower-rated CLO tranches, may cease to exist during such period.

**Market and Geopolitical Risk**

The value of your investment in the Fund is based on the values of the Fund's investments, which change due to economic and other events that affect the U.S. and global markets generally, as well as those that affect or are perceived or expected to affect particular regions, countries, industries, companies, issuers, sectors, asset classes 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 (i.e., increase the risk that the Fund will not be able to pay redemption proceeds within the allowable time period). In addition, no active trading market may exist for certain investments held by the Fund, which may impair the ability of the Fund to sell or to realize the current valuation of such investments in the event of the need to liquidate such assets.

The increasing interconnectivity between global economies and markets increases the likelihood that events or conditions in one region or market, or with respect to one company, may adversely impact other companies and other issuers, including those in a different country, region, sector, industry, or market. For example, adverse developments in the banking or financial services sector could impact companies operating in various sectors or industries and adversely impact the Fund's investments. Securities in the Fund's portfolio may underperform or otherwise be adversely affected due to inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates (or changes in interest rates), global demand for particular products or resources, market or

financial system instability or uncertainty, embargoes, the threat or actual imposition of tariffs, sanctions and other trade barriers, natural disasters and extreme weather events, health emergencies (such as epidemics and pandemics), terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events, such as terrorist attacks, natural disasters, health emergencies, social and political (including geopolitical) discord and tensions or debt crises and downgrades, among others, may result in increased 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 or expected inflation rates may adversely affect market and economic conditions, an issuer's financial condition, the Fund's investments and an investment in the Fund. The market price of debt securities generally falls as inflation increases because the purchasing power of the future income and repaid principal is expected to be worth less when received by the Fund. The risk of inflation is greater for debt instruments with longer maturities and especially those that pay a fixed rather than variable interest rate. 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 or economies may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). In general, the securities or other instruments that the Adviser believes represent an attractive investment opportunity or in which the Fund seeks to invest may be unavailable entirely or in the specific quantities sought by the Fund. As a result, the Fund may need to obtain the desired exposure through a less advantageous investment, forgo the investment at the time or seek to replicate the desired exposure through a derivative transaction or investment in another investment vehicle. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund's portfolio. There is a risk that you may lose money by investing in the Fund.

Social, political, economic and other conditions and events, such as war, natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, conflicts, social unrest, recessions, inflation, interest rate changes, the imposition of tariffs, trade restrictions or similar actions by the U.S. or foreign governments (or retaliatory measures taken in response to such actions) and supply chain disruptions could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and generally have a significant impact on economies, financial markets, issuers 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, can be adversely affected by changes in local and global economic conditions, including those 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, particularly when such responses are unprecedented, 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 price of performance of the Fund's investments, reduce market liquidity adversely affect and increase the volatility of markets and the Fund's share price, exacerbate pre-existing political, social, financial and economic risks to the Fund and cause overall declines in the U.S. and global markets. 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 (including monetary and/or fiscal actions intended to stimulate or stabilize the global economy) 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. Monetary and/or fiscal actions taken by U.S. or foreign governments may not be effective and could lead to increased market volatility. In addition, government actions (such as changes to interest rates) could have unintended economic and market consequences that adversely affect the Fund's investments. The frequency and magnitude of resulting changes in the value of the Fund's investments cannot be predicted.

**Emerging Market Securities**

The Fund may invest in emerging market or developing countries, which are countries that major international financial institutions generally consider to be less economically mature than developed nations (such as the United States or most nations in Western Europe). Emerging market or developing countries may be more likely to experience political turmoil or rapid changes in economic conditions than more developed countries, and the financial condition of issuers in emerging market or developing countries may be more precarious than in other countries. Certain emerging market countries may be subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping and therefore, material information related to an investment may not be

**35**

------

[Back to **Table of Contents**](#TOC_16872)

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

available or reliable. Such emerging market countries could also subject the Fund to greater risk associated with the custody of its securities than developed markets, which may adversely affect the Fund. In addition, the Fund's investments (including the companies in which the Fund may invest) in emerging market or developing countries may be subject to expropriation, nationalization and confiscation of assets and property. Furthermore, the Fund is limited in its ability to exercise its legal rights or enforce a counterparty's legal obligations in certain jurisdictions outside of the United States, in particular, in emerging markets countries. In addition, due to jurisdictional limitations, U.S. authorities (e.g., SEC and the U.S. Department of Justice) may be limited in their ability to enforce regulatory or legal obligations in emerging market countries. In addition, emerging market securities generally are less liquid and subject to wider price and currency fluctuations than securities issued in more developed countries. These characteristics result in greater risk of price volatility in emerging market or developing countries, which may be heightened by currency fluctuations relative to the U.S. dollar.

**ESG Investment Risk**

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

**Large Shareholder Transactions Risk**

The Fund may experience adverse effects when certain shareholders, or shareholders collectively, 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 result in gains for the Fund, which may increase taxable distributions to shareholders, 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 with respect to the Eaton Vance CLO Investment Grade Income ETF and the Nasdaq Stock Market LLC with respect to the Eaton Vance High Income Municipal ETF (collectively, the "Listing Exchange") and may, therefore, have a material upward or downward effect on the market price of the shares.

**LIBOR Discontinuance or Unavailability Risk**

The Fund's investments, payment obligations and financing terms may be based on floating rates, such as the London Interbank Offered Rates (collectively, "LIBOR"), Euro Interbank Offered Rate, Secured Overnight Financing Rate ("SOFR") and other similar types of reference rates (each, a "Reference Rate"). These Reference Rates are generally intended to represent the rate at which contributing banks may obtain short-term borrowings from each other within certain financial markets. London Interbank Offered Rate ("LIBOR") was the basic rate of interest used in lending transactions between banks on the London interbank market and has been widely used as a reference for setting the interest rate on loans globally. As a result of benchmark reforms, publication of LIBOR settings has ceased. Certain regulators and industry groups have taken actions to establish alternative reference rates (e.g., the SOFR, which measures the cost of overnight borrowings through repurchase agreement transactions collateralized with U.S. Treasury securities and is intended to replace U.S. dollar LIBORs with certain adjustments). These developments could negatively impact financial markets in general and present heightened risks, including with respect to the Fund's investments. As a result of the uncertainty and developments relating to the transition process, performance, price volatility, liquidity and value of the Fund and its assets may be adversely affected.

**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

**36**

Eaton Vance \| **Additional Information About Fund Investment Strategies and Related Risks**

Additional Information About Fund Investment Strategies and Related Risks (Con't)

maintained in an amount at least equal to the market value of the securities loaned. The Fund may engage in securities lending to seek 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.

**ETF Structure Risks**

*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. There can be no assurance that an active trading market for the Fund's shares will develop or be maintained. 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, such as during periods of market stress, and no other authorized participant creates or redeems, shares may trade at a discount to net asset value ("NAV") and possibly face trading halts and/or delisting. Authorized participant concentration risk may be heightened to the extent the Fund invests in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.<br>

*Cash Transactions Risk.* Unlike certain ETFs, the Fund may effect its creations and redemptions in cash or partially in cash. As a result, an investment in the 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. To the extent the Fund effects its redemptions in-kind, the in-kind redemption mechanism generally will not lead to a tax event for the Fund or its non-redeeming shareholders. If the 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 the Fund recognizes gain on these sales, this generally will cause the 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. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the 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.<br>

*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. You may pay significantly more or receive significantly less than the Fund's NAV per share during periods when there is a significant premium or discount.<br>

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 the 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.<br>

Additional Information About Fund Investment Strategies and Related Risks (Con't)

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

**Temporary 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. For example, with respect to the Eaton Vance High Income Municipal ETF, when the Adviser believes that conditions warrant, including when suitable municipal obligations are unavailable, the Fund may invest without limit in securities subject to federal income tax or in securities that pay interest income subject to the federal alternative minimum tax. Under such circumstances, a higher portion of the Fund's distributions will likely be subject to federal income tax and/or the federal alternative minimum tax. If the Adviser incorrectly predicts the effects of these changes or during periods of temporary defensive or other temporary positions, such temporary investments may adversely affect the Fund's performance and the Fund may not achieve its investment objective.

**Investment Company Securities**

Subject to the limitations set forth in the 1940 Act, or as otherwise permitted by the SEC, the Fund may acquire shares in other investment companies, including foreign investment companies, closed-end funds, ETFs and money market funds which may be managed by the Adviser or its affiliates. The market value of the shares of other investment companies may differ from the NAV of the Fund. The shares of certain investment companies, principally closed-end investment companies, frequently trade at a discount to their NAV. As a shareholder in an investment company, the Fund would bear its ratable share of that entity's expenses, including its investment advisory and administration fees and be subject to the associated risks. At the same time, the Fund would continue to pay its own advisory and administration fees and other expenses. As a result, the Fund and its shareholders will directly bear the expenses of their investment in the Fund and indirectly bear the expenses of the Fund's investments in other investment companies.

**Taxability Risk**

Changes in tax laws or adverse determinations by the Internal Revenue Service ("IRS") may make the income from some municipal obligations taxable and adversely affect the value of such obligations.

**Cybersecurity Risk**

With the increased use of technologies such as the internet to conduct business, the Fund, the Adviser, 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), exchanges, market participants, 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.

**Regulatory and Legal Risk**

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

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

**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. Moreover, a new fund may not be able to fully implement its investment strategy immediately upon commencing investment operations, which could reduce investment performance.

Eaton Vance \| **Fund Management**

Fund Management

Adviser

Morgan Stanley Investment Management Inc., with principal offices at 1585 Broadway, New York, NY 10036, conducts a worldwide portfolio management business and provides a broad range of portfolio management services to customers in the United States and abroad. Morgan Stanley (NYSE: "MS") is the parent of the Adviser. 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 December 31, 2024, the Adviser, together with its affiliated asset management companies, had approximately $1.7 trillion in assets under management or supervision.

A discussion regarding the basis for the Board of Trustees' approval of the Management Agreement will be available in the Fund's report filed on Form N-CSR once available.

The Adviser and/or its affiliates may make payments to one or more investors that contribute seed capital to the Fund. Such payments may continue for a specified period of time and/or until a specified dollar amount is reached. Those payments will be made from the assets of the Adviser and/or such affiliates (and not the Fund). Seed investors may contribute all or a majority of the assets in the Fund. There is a risk that such seed investors may redeem their investments in the Fund. As with redemptions by other large shareholders, such redemptions could have a significant negative impact on the Fund.

Management Fees

The Adviser receives a fee for management services equal to the portion of the average daily net assets as set forth in the table below.

---

Shareholder Information

**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 as a result of the occurrence of a significant event or 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. In these cases, the Fund's NAV will reflect certain portfolio securities' fair value rather than their market price. In addition, the securities held by the Fund may be traded in markets that close at a different time than the exchange on which the Fund's shares are listed. Accordingly, during the time when the Fund's listing exchange is open but after the applicable market closes, bid-ask spreads may widen and Fund shares may trade at a premium or discount to NAV. 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 Fund 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

**41**

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.

Eaton Vance CLO Investment Grade Income ETF's primary listing exchange is NYSE Arca and Eaton Vance High Income Municipal ETF's primary listing exchange is The Nasdaq Stock Market LLC. Each Listing Exchange 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, the Listing Exchange 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 the Listing Exchange 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 a Fund's shares may be purchased and sold on the Listing Exchange at prevailing market prices, the risks of frequent trading are limited.

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

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

**Creations and Redemptions**

Prior to trading in the secondary market, shares of the Fund are "created" at NAV by market makers, large investors and institutions only in block-size Creation Units or multiples thereof. Each "creator" or authorized participant (an "Authorized Participant") enters into an authorized participant agreement with the Fund's Distributor. An Authorized Participant is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units.

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

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

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

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

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

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

The in-kind arrangements are intended to protect ongoing shareholders from adverse effects on the Fund's portfolio that could arise from frequent cash creation and redemption transactions and generally will not lead to a tax event for the Fund or its ongoing shareholders.

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.

**Inactive Accounts and Risk of Escheatment**

In accordance with state "unclaimed property" laws, your Fund shares may legally be considered abandoned and required to be transferred to the relevant state (also known as "escheatment") under various circumstances. These circumstances, which vary by state, can include inactivity (e.g., no owner-initiated contact for a certain period), returned mail (e.g., when mail sent to a shareholder is returned by the post office as undeliverable), uncashed checks or a combination of these. An incorrect address may cause a shareholder's account statements and other mailings to be returned to the Fund or your financial intermediary. Since states' statutory requirements regarding inactivity differ, it is important to regularly contact your financial intermediary or the Fund's transfer agent. The process described above, and the application of state escheatment laws, may vary by state and/or depending on how shareholders hold their shares in the Fund. Escheatment with respect to a retirement account is subject to a 10% federal withholding on the account.

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

**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.

*Taxation of Distributions.* With respect to the Eaton Vance CLO Investment Grade Income ETF, 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 distributions would be eligible for the reduced rate of taxation applicable to qualified dividend income or for a dividends-received deduction.

With respect to the Eaton Vance High Income Municipal ETF, your income dividend distributions are normally exempt from federal income tax—to the extent they are derived from municipal obligations. Income derived from other portfolio securities may be subject to federal, state and/or local income taxes. Income derived from some municipal securities is subject to the federal alternative minimum tax. Certain tax-exempt securities whose proceeds are used to finance private, for-profit organizations are subject to this special tax system that ensures that individuals pay at least some federal taxes. Although interest on these securities is generally exempt from federal income tax, some individual taxpayers who have many tax deductions or exemptions nevertheless may have to pay tax on the income. However, the alternative minimum tax consequences discussed in this paragraph do not apply with respect to interest paid on bonds issued after December 31, 2008 and before January 1, 2011 (including refunding bonds issued during that period to refund bonds originally issued after December 31, 2003 and before January 1, 2009).

The Eaton Vance High Income Municipal ETF may derive gains in part from municipal obligations that the Fund purchased below their principal or face values. All or a portion of these gains may be taxable to you as ordinary income rather than capital gains. If the Fund makes any capital gain distributions, those distributions will normally be subject to federal and state income tax when they are paid, whether you take them in cash or reinvest them in Fund shares. Any short-term capital gain distributions are taxable to you as ordinary income. Any long-term capital gain distributions are taxable to you as long-term capital gains, no matter how long you have owned shares in the Fund. The Fund does not anticipate that it will make any distributions eligible for the reduced rate of taxation applicable to qualified dividend income or for a dividends-received deduction.

The Fund's transactions in derivatives will be subject to special tax rules, the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, and convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund's use of these types of transactions may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions.

If you borrow money to purchase shares of the Eaton Vance High Income Municipal ETF, the interest on the borrowed money is generally not deductible for income tax purposes.

Shareholder Information (Con't)

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

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

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

*Taxation of Sales.* Your sale of Fund shares normally is subject to federal and state income tax and may result in a taxable gain or loss to you. A sale also may be subject to local income tax. 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. Further, any loss realized on the sale of shares held for six months or less may be disallowed to the extent of any distributions treated as exempt-interest dividends with respect to the shares. Additionally, any loss realized on a sale 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 (other than exempt-interest dividends) 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 a Fund to enable the Fund to determine whether withholding is required.

Reporting to you and the IRS is required annually on Form 1099-B with respect to 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. These activities could cause Morgan Stanley to have an interest that is different from, and potentially adverse to, that of the Fund, which may impede the Fund from participating in certain opportunities. 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 sponsored, managed, or advised by the Adviser or one of its investment adviser affiliates, 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, the Adviser and/or the Adviser's investment adviser affiliates 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.

The conflicts summarized herein do not purport to be a complete list or explanation of the conflicts associated with the financial or other interests the Adviser or its affiliates may have now or in the future. For more information about conflicts of interest, see the section entitled "Potential Conflicts of Interest" in the SAI. Conflicts of interest not described below or in the SAI may also exist. References to the Adviser in this section include the Fund's affiliated sub-adviser (if any) unless otherwise noted.

*Material Nonpublic and Other 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 disposition opportunity, including for an extended period of time. This inability to buy or sell an investment could have an adverse effect on the Fund's portfolio due to, among other things, changes in an investment's value during the period its trading is restricted. Morgan Stanley has established certain information barriers and other policies designed to address the sharing of information between different businesses within Morgan Stanley. As a result of information barriers, the Adviser, in certain instances, will not have access, or will have limited access, to certain information and personnel in other areas of Morgan Stanley and, in such instances, will not manage the Fund with the benefit of the information held by such other areas. In other instances, Morgan Stanley personnel, including personnel of the Adviser, will have access to information and personnel of its affiliates. In managing conflicts of interest that arise because of the foregoing, the Adviser generally will be subject to fiduciary requirements. The Adviser also may implement internal information barriers or ethical walls or other internal information sharing protocols, and the conflicts described herein with respect to information barriers and otherwise with respect to Morgan Stanley and the Adviser will also apply internally within the Adviser. Information sharing 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 the sharing of information). The Adviser may face conflicts of interest in determining whether to engage in the sharing of information with its affiliates.

*Investments by Morgan Stanley and its Affiliated Investment Accounts.* In serving in multiple capacities to Affiliated Investment Accounts, Morgan Stanley, including the Adviser and its investment teams, 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. An investment team may have obligations to Affiliated Investment Accounts managed by both the Adviser and one or more of the Adviser's investment adviser affiliates. 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 or its investment adviser affiliates. 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, Distributor and/or their affiliates 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 the 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

Shareholder Information (Con't)

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.

Continuous Offering Information

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.
