SEC File No. 811-06515 and 033-44782

SUPPLEMENT DATED JUNE 23, 2025 TO THE SUMMARY PROSPECTUSES, PROSPECTUSES,<br> AND STATEMENT OF ADDITIONAL INFORMATION OF

Morgan Stanley Income Opportunities Fund, dated February 28, 2025, as amended June 23, 2025

As previously announced, at a meeting held on April 23-24, 2025, the Board of Trustees (the "Board") of Morgan Stanley Income Opportunities Fund (formerly, Morgan Stanley Global Fixed Income Opportunities Fund) (the "Acquired Fund") unanimously approved the reorganization of the Acquired Fund into an exchange-traded fund ("ETF"), which will be managed by Morgan Stanley Investment Management Inc. ("MSIM"), which is also the investment adviser to the Acquired Fund. The Board, which is comprised solely of Trustees who are not "interested persons" (as defined in the Investment Company Act of 1940, as amended) of the Acquired Fund, determined that participation in the Reorganization (defined below) is in the best interests of the Acquired Fund and the interests of existing shareholders of the Acquired Fund ("Acquired Fund Shareholders") will not be diluted as a result of the Reorganization.

Subject to shareholder approval, the Acquired Fund will be reorganized into the Eaton Vance Income Opportunities ETF (the "Acquiring Fund" and together with the Acquired Fund, the "Funds"), a series of Morgan Stanley ETF Trust (the "Acquiring Fund Trust") (the "Reorganization").

In addition, Michael Kushma will no longer be a portfolio manager of the Funds effective December 31, 2025. Accordingly, all references to Mr. Kushma will be removed from the Summary Prospectuses, Prospectuses and Statement of Additional Information on December 31, 2025.

If approved by Acquired Fund Shareholders, the Reorganization would be accomplished in accordance with an Agreement and Plan of Reorganization (the "Plan"). Subject to shareholder approval, the Reorganization is anticipated to occur (after the close of trading) on or about November 7, 2025 (the "Closing Date"). This supplement is not a solicitation of proxy.

The Plan provides for the transfer of substantially all of the assets of the Acquired Fund to the Acquiring Fund in exchange for the assumption by the Acquiring Fund of the Acquired Fund's stated liabilities and shares of the Acquiring Fund ("Acquiring Fund Shares") having an aggregate net asset value ("NAV") equal to the aggregate NAV of the Acquired Fund followed immediately by the distribution by the Acquired Fund to Acquired Fund Shareholders of the portion of Acquiring Fund Shares to which the Acquired Fund Shareholder is entitled (and cash with respect to any fractional shares), in accordance with the Plan and except as noted below. Following the Reorganization, the Acquired Fund will be liquidated.

Acquired Fund Shareholders of record on July 17, 2025 will receive a combined Proxy Statement and Prospectus that contains important information about the Reorganization and the Acquiring Fund, including information regarding the Acquiring Fund's investment strategies and risks, fees and expenses.

If Acquired Fund Shareholders approve the Reorganization, and certain other closing conditions are satisfied or waived, Acquired Fund Shareholders who own shares of the Acquired Fund ("Acquired Fund Shares") through a brokerage account that can accept shares of an ETF will become shareholders of the Acquiring Fund (which will operate as an ETF) receiving Acquiring Fund Shares with an aggregate value equal to the aggregate NAV of their Acquired Fund Shares held immediately prior to the Reorganization, except with respect to cash received in lieu of fractional Acquiring Fund Shares, which cash payment may be taxable.

The Acquiring Fund is a series of the Acquiring Fund Trust and will not commence operations until the consummation of the Reorganization. The Acquired Fund and the Acquiring Fund have identical investment objectives and principal investment strategies. However, there are important differences between the Acquired Fund and the Acquiring Fund. For example, although the Acquiring Fund will be subject to similar investment risks as the Acquired Fund, the Acquiring Fund will be subject to additional risks, such as structural risks related to ETFs, which will be described in the combined Proxy Statement and Prospectus. In addition, the Acquired Fund and the Acquiring Fund have substantially similar fundamental investment policies. However, the Acquired Fund's investment objectives are "fundamental" (*i.e.*, they may not be changed without shareholder approval) whereas the Acquiring Fund's investment objectives may be changed without shareholder approval with notice to shareholders of the Acquiring Fund ("Acquiring Fund Shareholders").

MSIM believes that the Reorganization will provide multiple benefits for Acquired Fund Shareholders, including additional trading flexibility, increased transparency and the potential for enhanced tax efficiency. However, given that the Acquiring Fund will effect some or all of its creations and redemptions in cash rather than in-kind, a shareholder will not benefit from the greater tax efficiency of the ETF structure to the same extent as a shareholder of an ETF that effects all of its creations and redemptions in-kind.

The Reorganization is structured to be a tax-free reorganization under the U.S. Internal Revenue Code of 1986, as amended. As a result, Acquired Fund Shareholders generally will not recognize a taxable gain (or loss) for U.S. tax purposes as a result of the Reorganization (except with respect to cash received or with respect to investors whose shares are redeemed prior to the Reorganization, as explained elsewhere in this Supplement).

In addition, in order to fund redemption transactions prior to and in connection with the Reorganization, the Acquired Fund may have to sell securities. These transactions may also result in net realized capital gains to the Acquired Fund, which may result in taxable distributions to shareholders either (i) by the Acquired Fund prior to the Reorganization or (ii) by the Acquiring Fund after the Reorganization. Furthermore, redemptions of a large number of Acquired Fund Shares relative to the size of the Acquired Fund may have adverse tax consequences limiting the use of any capital loss carryforwards and certain other losses of the Acquired Fund to offset any future realized capital gains.

**Importantly, in order to receive Acquiring Fund Shares as part of the Reorganization, Acquired Fund Shareholders must hold their Acquired Fund Shares through a brokerage account that can accept shares of an ETF (*i.e.*, the Acquiring Fund). If Acquired Fund Shareholders do not hold their Acquired Fund Shares through that type of brokerage account, they will not receive Acquiring Fund Shares as part of the Reorganization. For Acquired Fund Shareholders that do not currently hold their Acquired Fund Shares through a brokerage account that can hold Acquiring Fund Shares, please see the Q&A that follows for additional actions that such Acquired Fund Shareholders must take to receive Acquiring Fund Shares as part of the Reorganization. Other than the approval by the requisite vote of Acquired Fund Shareholders, no further action is required for Acquired Fund Shareholders that hold Acquired Fund Shares through a brokerage account that can hold Acquiring Fund Shares.**

If (and only if) the Reorganization is approved by Acquired Fund Shareholders, it is expected that effective on or about the first business day of the month following shareholder approval of the Reorganization (the "Effective Date"), the following fees will be waived: (i) the sales charge on purchases of Class A shares of the Acquired Fund; (ii) the contingent deferred sales charge ("CDSC") on Class A and Class C shares of the Acquired Fund; (iii) the 12b-1 fees for any applicable share class of the Acquired Fund; and (iv) any finder's fee payments applicable to any class of shares of the Acquired Fund. Also, effective on the Effective Date, any current Letter of Intent under which Class A shares of the Acquired Fund were purchased would be considered completed. In addition, it is currently expected that if (and only if) the Reorganization is approved by Acquired Fund Shareholders, effective on the Effective Date, the Acquired Fund will be closed to new investors.

The Summary Prospectuses, Prospectuses and Statement of Additional Information will be amended accordingly.

**IMPORTANT NOTICE ABOUT YOUR FUND ACCOUNT<br> QUESTIONS AND ANSWERS**

The following is a brief Q&A that provides information to help you to determine if you need to take action with respect to your shareholder account prior to the Reorganization in order to receive Acquiring Fund Shares.

**Q. How will the Reorganization affect me as a shareholder?**

**A.** If the Reorganization is consummated, you will cease to be a shareholder of the Acquired Fund. In order to receive Acquiring Fund Shares as part of the Reorganization, you must hold your Acquired Fund Shares through a brokerage account that can accept shares of an ETF on the Closing Date of the Reorganization. If you hold your Acquired Fund Shares through a brokerage account that can accept shares of an ETF on the Closing Date of the Reorganization, you will automatically become a shareholder of the Acquiring Fund. As described in more detail above, upon completion of the Reorganization, you will (subject to certain exceptions) receive Acquiring Fund Shares and, in some cases, cash that, combined with the Acquiring Fund Shares, is equal in value to the aggregate NAV of your Acquired Fund Shares on the Closing Date of the Reorganization. Acquiring Fund Shares will not be issued in fractional shares. As a result, cash will be paid to Acquired Fund Shareholders in lieu of fractional Acquiring Fund Shares, which cash payment may be taxable. Following the Reorganization, Acquiring Fund Shareholders may bear certain costs with respect to maintaining brokerage accounts and buying and selling Acquiring Fund Shares in the secondary market that Acquired Fund Shareholders do not experience as shareholders of the Acquired Fund. In addition, the market price of ETF 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.

**As discussed below, if the Reorganization is approved by Acquired Fund Shareholders and you desire to hold Acquiring Fund Shares, it is important for you to determine that you hold your Acquired Fund Shares in the type of account that can accommodate the receipt of the ETF shares that will be received in the Reorganization or, if you do not own Acquired Fund Shares through such an account, that you take necessary actions to be able to receive Acquiring Fund Shares.**

**Q. What will happen if I do not have a brokerage account that can accept Acquiring Fund Shares at the time of the Reorganization?**

**A**. If you do not have a brokerage account that can accept Acquiring Fund Shares at the time of the Reorganization, you will not receive Acquiring Fund Shares in connection with the Reorganization. Instead, depending on the type of account through which you hold your Acquired Fund Shares, you will either receive cash or R Shares of Morgan Stanley U.S. Government Money Market Trust equal in value to the aggregate NAV of your Acquired Fund Shares on the Closing Date of the Reorganization (except as discussed below with respect to non-accommodating retirement accounts). In some cases, the liquidation of your investment and return of cash, or the transfer of your investment, may be subject to fees and expenses. In addition, the liquidation or transfer of your investment may be subject to tax. More detail is provided below with respect to the types of accounts that cannot hold Acquiring Fund Shares and what will happen if you own your investment in the Acquired Fund through such accounts.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Non-Accommodating Brokerage Accounts:*** If
you hold Acquired Fund Shares in a brokerage account with a financial intermediary that only allows the client to hold shares of mutual
funds in the account, you will need to contact your financial intermediary to set up a brokerage account that permits investments in ETF
shares. If such a change is not made before the Reorganization, you will not receive Acquiring Fund Shares as part of the Reorganization.
Instead, your investment will be liquidated. You will receive cash, which will be equal in value to the aggregate NAV of your Acquired
Fund Shares calculated as of the Closing Date of the Reorganization.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Non-Accommodating Retirement Accounts:*** If you hold Acquired Fund Shares through an individual retirement account ("IRA") or group retirement plan whose plan
sponsor does not have the ability to hold shares of ETFs on its platform, you may need to redeem your shares prior to the Reorganization
or, if applicable, your financial intermediary may transfer your investment in the Acquired Fund to a different investment option prior
to the Reorganization.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Fund Direct Accounts:*** If you hold
Acquired Fund Shares in an account directly with the Acquired Fund at its transfer agent, SS&C Global Investor and Distribution Solutions, Inc.
("SS&C GIDS") (a "fund direct account"), you should transfer your Acquired Fund Shares to a brokerage account
that can accept Acquiring Fund Shares prior to the Reorganization. If such a change is not made before the Reorganization, you will not
receive Acquiring Fund Shares as part of the Reorganization. Instead, your investment will be liquidated. You will receive cash, which
will be equal in value to the aggregate NAV of your Acquired Fund Shares calculated as of the Closing Date of the Reorganization.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Fund Direct IRA:*** If you hold Acquired
Fund Shares through an IRA directly with the Acquired Fund at its transfer agent, SS&C GIDS, and do not take action to transfer the
investment in the Acquired Fund to a different investment option prior to the Reorganization, your Acquired Fund Shares will be exchanged
for R Shares of Morgan Stanley U.S. Government Money Market Trust equal in value to the aggregate NAV of your Acquired Fund Shares on
the Closing Date of the Reorganization unless you provide alternative direction prior to the final date to exchange shares of the Acquired
Fund. The final date to exchange shares of the Acquired Fund is the second business day immediately preceding the Closing Date (and the
Closing Date is anticipated to be on or about November 7, 2025).

It may take time for you to receive your cash. Please consult with your financial intermediary or tax advisor for more information on the impact that the Reorganization would have on you and your investments.

If you do not currently hold your Acquired Fund Shares through a brokerage account that can hold Acquiring Fund Shares, please see the information below for additional actions that you must take to receive Acquiring Fund Shares as part of the Reorganization. Other than the approval by the requisite vote of Acquired Fund Shareholders, no other action on the part of Acquired Fund Shareholders is required for shareholders that hold Acquired Fund Shares through a brokerage account that can hold Acquiring Fund Shares.

**If you are unsure about the ability of your account to accept Acquiring Fund Shares (*i.e.*, ETF shares), please call 1-800-869-6397 or contact your financial advisor or other financial intermediary.**

After the Reorganization, individual Acquiring Fund Shares may only be purchased and sold in the secondary market. Acquiring Fund Shares will be listed for trading on the NYSE Arca. Acquiring Fund Shares may also be traded on other national securities exchanges, electronic crossing networks, and other alternative trading systems. Should you decide to purchase or sell Acquiring Fund Shares after the Reorganization, you will need to place a trade through a broker who will execute your trade in the secondary market at prevailing market prices. Because Acquiring Fund Shares will trade at market prices rather than at NAV, Acquiring Fund Shares may trade at a price less than (discount), at, or greater than (premium) the Acquiring Fund's NAV per share. As with all transactions for ETFs, your broker may charge a commission for purchase and sale transactions. In addition, the market price of ETF 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.

**Q. How do I transfer my Acquired Fund Shares from a fund direct account to a brokerage account that will accept Acquiring Fund Shares?**

**A.** Transferring your Acquired Fund Shares from a fund direct account to a brokerage account that can accept Acquiring Fund Shares should be a simple process. If you have a brokerage account or a relationship with a brokerage firm, please talk to your broker and inform the broker that you would like to transfer a mutual fund position that you hold directly with the Acquired Fund into your brokerage account. Also, inform your broker that such an account will need to be set up to accept shares of an ETF, such as the Acquiring Fund. If you don't have a brokerage account or a relationship with a brokerage firm, you will need to open an account.

It is suggested that you provide your broker with a copy of your quarterly account statement from the Acquired Fund. Your broker will require your account number with the Acquired Fund, which can be found on your statement. Your broker will help you complete a form to initiate the transfer. Once you sign that form, your broker will submit the form to the transfer agent directly, and the shares will be transferred into your brokerage account. ***The sooner you initiate the transfer, the better.***

**Q. How do I transfer my Acquired Fund Shares from a non-accommodating brokerage account to a brokerage account that will accept Acquiring Fund Shares?**

**A.** The broker where you hold your Acquired Fund Shares should be able to assist you in changing the characteristics of your brokerage account to an account that is permitted to invest in ETF shares. Contact your broker to make the necessary changes to your account. ***The sooner you initiate making these changes, the better.***

**Q. What if I do not want to own Acquiring Fund Shares?**

**A.** If the Reorganization is approved by Acquired Fund Shareholders and you do not want to receive Acquiring Fund Shares in connection with the Reorganization, you can exchange your Acquired Fund Shares for shares of another Morgan Stanley mutual fund that is not participating in the Reorganization or redeem your Acquired Fund Shares. Prior to doing so, however, you should consider the tax consequences associated with either action. Redemption of your Acquired Fund Shares will be a taxable event if you hold your shares in a taxable account. The last date to redeem your Acquired Fund Shares or exchange them into another Morgan Stanley mutual fund prior to the Reorganization is the second business day immediately preceding the Closing Date (and the Closing Date is anticipated to be on or about November 7, 2025).

**ADDITIONAL INFORMATION ABOUT THE REORGANIZATION**

**Q: How will the Acquired Fund change post-conversion?**

**A:** The table below summarizes certain differences between the Acquiring Fund and Acquired Fund. There are also differences between the fee and expense arrangements for the Acquired Fund and Acquiring Fund. The fee and expense structure of the Acquiring Fund is described below.

\* Mr. Kushma will no longer be a portfolio manager of the Funds effective December 31, 2025.

\*\* Began managing the Acquired Fund on May 30, 2025. Prior to such date, other individuals served as portfolio managers of the Acquired Fund along with Michael Kushma.

**Q: What are the differences between an ETF and a mutual fund?**

A: ETFs are structurally different from mutual funds in several important aspects:

&nbsp;&nbsp;&nbsp;&nbsp;· A mutual fund may offer multiple share classes
with different sales charges, expenses, and/or minimum investments. The Acquiring Fund does not issue multiple classes of shares.

&nbsp;&nbsp;&nbsp;&nbsp;· A mutual fund investor may purchase and redeem
shares directly from the mutual fund (through a distributor or a financial intermediary). Most ETF investors will buy and sell shares
in secondary market transactions through brokers.

&nbsp;&nbsp;&nbsp;&nbsp;· A mutual fund will accept purchase and redemption
orders from any shareholders, and only on days that the mutual fund is open for business, and those orders will be effected at that day's
NAV per share. An ETF will issue or redeem shares at its NAV per share only in one or more groupings of a large specified number of shares
called a "Creation Unit," on days that the ETF is open for business. Only an ETF's "authorized participants"
are permitted to engage in creation or redemption transactions directly with the ETF. All other shareholders will buy and sell shares
of the ETF on an exchange at market price which may be above (at a premium), at, or below (at a discount) NAV or the intraday value of
the ETF's holdings. An authorized participant is a member or participant of a clearing agency registered with the Securities and
Exchange Commission (the "SEC"), which has a written agreement with the Acquiring Fund and or one of its service providers
that allows the authorized participant to place orders for the purchase and redemption of Creation Units.

As a result of these structural differences, there are certain anticipated benefits associated with the ETF structure, including, but not limited to the following:

&nbsp;&nbsp;&nbsp;&nbsp;· *Additional Trading Flexibility.* As a shareholder
of the Acquired Fund, you can only purchase or redeem Acquired Fund Shares at a price based on the Acquired Fund's NAV that is next
calculated after your order is received by the Acquired Fund. This NAV is calculated once per business day. As a shareholder of the Acquiring
Fund, however, you will have additional trading flexibility by being able to purchase and sell Acquiring Fund Shares throughout a trading
day on the secondary market. These trades will occur at market prices, which may be higher or lower than the Acquiring Fund's NAV
per share. This intraday liquidity will give you the opportunity to act on purchase and sale decisions immediately, rather than waiting
to transact at the Acquiring Fund's NAV.

&nbsp;&nbsp;&nbsp;&nbsp;· *Increased Transparency*. Currently, the
Acquired Fund only provides periodic disclosure of its complete portfolio holdings. The Acquiring Fund will make its complete portfolio
holdings public each business day. This holdings information, along with other information about the Acquiring Fund, will be found on
the Acquiring Fund's website at www.eatonvance.com.

&nbsp;&nbsp;&nbsp;&nbsp;· *Potential for Enhanced Tax Efficiency.* Current
Acquired Fund Shareholders are expected to benefit directly from the potential for greater tax efficiency and trading efficiency with
the ETF structure, as ETFs generally experience fewer portfolio transactions than mutual funds due to the secondary market liquidity of
the ETF structure. However, given that the Acquiring Fund will effect some or all of its creations and redemptions in cash rather than
in-kind, a shareholder will not benefit from the greater tax efficiency of the ETF structure to the same extent as a shareholder of an
ETF that effects all of its creations and redemptions in-kind.

There are, however, certain risks associated with the ETF structure as well, including, but not limited to the following:

&nbsp;&nbsp;&nbsp;&nbsp;· *Authorized Participant Concentration Risk.* Only an authorized participant may engage in creation or redemption transactions directly with the Acquiring Fund. The Acquiring 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 Acquiring Fund 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 Acquiring Fund, such as during periods of market stress, and no other authorized participant
creates or redeems, Acquiring Fund Shares may trade at a discount to NAV and possibly face trading halts and/or delisting. Authorized
participant concentration risk may be heightened to the extent the Acquiring Fund invests in securities issued by non-U.S. issuers or
other securities or instruments that have lower trading volumes.

&nbsp;&nbsp;&nbsp;&nbsp;· *Cash Transactions Risk.* Unlike certain
ETFs, the Acquiring 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 Acquiring Fund might not have recognized if it were to distribute portfolio
securities in-kind. As such, investments in Acquiring Fund Shares may be less tax-efficient than an investment in an ETF that distributes
portfolio securities entirely in-kind.

&nbsp;&nbsp;&nbsp;&nbsp;· *Trading Risk.* The market prices of Acquiring
Fund Shares are expected to fluctuate, in some cases materially, in response to changes in the Acquiring Fund's NAV, the intra-day
value of the Acquiring Fund's holdings, and supply and demand for Acquiring Fund Shares. MSIM 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 Acquiring Fund's holdings.
You may pay significantly more or receive significantly less than 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 Acquiring Fund Shares. In addition, the market price of Acquiring Fund 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 Acquiring Fund Shares will vary over time based on the Acquiring Fund's trading volume and
market liquidity and may increase if the Acquiring Fund's trading volume, the spread of the Acquiring Fund's underlying securities,
or market liquidity decrease.

Following the Reorganization, shareholders may bear certain costs with respect to maintaining brokerage accounts and buying and selling Acquiring Fund Shares in the secondary market that shareholders do not experience as shareholders of the Acquired Fund.

**Q: Is the Reorganization expected to affect the way my investments are managed?**

A: The Reorganization is not expected to affect the way the Acquired Fund's investments are managed. As previously announced, there were certain changes made to the Acquired Fund, including changes to the Acquired Fund's name, principal investment strategies and benchmark index, which went into effect on May 30, 2025. The Acquired Fund and the Acquiring Fund have identical investment objectives and principal investment strategies. There are several important differences between the Acquired Fund and the Acquiring Fund with respect to their principal investment risks due to the ETF structure, as described above and as will be described in the combined Proxy Statement and Prospectus. In addition, the Acquired Fund and the Acquiring Fund have substantially similar fundamental investment policies. However, the Acquired Fund's investment objectives are "fundamental" (*i.e*., they may not be changed without shareholder approval) whereas the Acquiring Fund's investment objectives may be changed without shareholder approval with notice to shareholders.

MSIM is the investment adviser to each of the Acquired Fund and Acquiring Fund. The same individuals responsible for the day-to-day portfolio management of the Acquired Fund will be responsible for the day-to-day portfolio management of the Acquiring Fund, with the addition of one portfolio manager. Prior to May 30, 2025, other individuals served as portfolio managers of the Acquired Fund along with Michael Kushma. As noted above, Mr. Kushma will no longer be a portfolio manager of the Funds effective December 31, 2025. The Acquiring Fund is a series of the Acquiring Fund Trust and will not commence operations until the consummation of the Reorganization.

**Q: What is the fee and expense structure of the Acquiring Fund?**

A: The Acquiring Fund employs a unitary fee structure pursuant to which MSIM bears substantially all operating expenses of the Acquiring Fund, subject to certain exceptions. MSIM has agreed to reduce its management fee so that Total Annual Fund Operating Expenses of the Acquiring Fund, excluding 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 Acquiring Fund's business, will not exceed 0.50%. The fee waiver will continue for two years from the date of the Reorganization or until such time as the Board of Trustees of Morgan Stanley ETF Trust acts to discontinue all or a portion of such waiver when it deems such action is appropriate. It is not expected that the fee waiver will be extended.

More information on the comparison of the fee and expense arrangements of the Acquired Fund and Acquiring Fund will be available in the combined Proxy Statement and Prospectus.

**Q: Will I be subject to comparable investment risks as a shareholder of the Acquiring Fund?**

A: Yes, the Acquiring Fund will be subject to similar investment risks as the Acquired Fund. However, there are important differences between the principal risks of the Acquired Fund and the Acquiring Fund, such as those described above with respect to ETF-specific structural risks.

**Q: How do the Funds' investment objectives, principal investment strategies, and fundamental investment policies compare?**

A: The Acquired Fund and the Acquiring Fund have identical investment objectives and principal investment strategies. The Acquired Fund and the Acquiring Fund have adopted substantially similar fundamental investment policies, which may not be changed without prior shareholder approval. However, the investment objectives for the Acquired Fund are "fundamental" (*i.e*., they may not be changed without shareholder approval) whereas the investment objectives of the Acquiring Fund may be changed without shareholder approval (but no change is currently anticipated, as will be described in the combined Proxy Statement and Prospectus).

**Q: Who will pay the costs in connection with the Reorganization?**

A: The Acquired Fund will pay the full costs associated with the Reorganization (including the legal costs associated with the Reorganization) and any transaction costs incurred by the Acquired Fund related to the disposition and acquisition of assets as part of the Reorganization.

If the Reorganization is not consummated, MSIM will pay for the full costs associated with the Reorganization.

Unlike mutual funds, ETFs may trade at a premium or discount to their NAV per share. Because ETF shares are traded in the secondary market, a broker may charge a commission to execute a transaction in the shares, and an investor may incur the cost of the spread between the price at which a dealer will buy shares and the price at which a dealer will sell shares.
