October 21, 2025

Dear Shareholder:

A joint special meeting (the "Special Meeting") of shareholders of the funds listed above (each, a "Fund" and together, the "Funds") will be held at the offices of the Funds, Eleven Madison Avenue, Floor 2B, New York, New York 10010, on Monday, December 15, 2025 at 2:00 p.m., Eastern Time, to vote on the proposals listed in the enclosed Joint Proxy Statement. You have received this letter because you were a shareholder of record of one of the Funds on October 10, 2025, the record date for the Special Meeting.

As discussed in more detail in the accompanying joint proxy statement, on May 28, 2025, UBS Asset Management (Americas) LLC ("UBS AM (Americas)"), each Fund's investment adviser, entered into a definitive agreement (the "Purchase Agreement") with O'Connor Alternative Investments, LLC ("O'Connor Alternative Investments"), an indirect wholly owned subsidiary of Cantor Fitzgerald, L.P., pursuant to which O'Connor Alternative Investments will acquire UBS AM (Americas)'s O'Connor investment platform (the "UBS/Cantor Transaction"). As part of the UBS/Cantor Transaction, it is expected that the O'Connor investment management and support teams, which include each Fund's portfolio management team, will transition to O'Connor Alternative Investments, subject to certain conditions. The UBS/Cantor Transaction is expected to close with respect to the Funds during the first quarter of 2026 (the "Closing Date"). O'Connor Alternative Investments has no operating history and has recently registered with the SEC as an investment adviser.

It is proposed that O'Connor Alternative Investments succeed UBS AM (Americas) as your Fund's investment adviser in connection with the UBS/Cantor Transaction. Your Fund is subject to the Investment Company Act of 1940, as amended (the "1940 Act"), which requires the Funds' current investment management agreement with UBS AM (Americas) (the "Current Investment Management Agreement") to terminate automatically upon its "assignment." Your Fund's current investment management agreement would therefore terminate automatically in the event it were assigned by UBS AM (Americas) to O'Connor Alternative Investments in connection with the UBS/Cantor Transaction. Accordingly, each Fund is seeking shareholder approval of a new investment management agreement with O'Connor Alternative Investments (the "New Investment Management Agreement") at the Special Meeting. The terms of the New Investment Management Agreement, including the advisory fee rate payable thereunder, will be identical to those of the Current Investment Management Agreement, except for the investment adviser, dates of execution, effectiveness and termination and certain other non-material changes. If approved by shareholders, the New Investment Management Agreement would take effect as of the Closing Date.

At the Special Meeting, shareholders will also be asked to elect four nominees (collectively, the "Trustee Nominees") to each Fund's Board of Trustees (each, a "Board") to succeed the current members of the Fund's Board (the "Current Trustees"). The Trustee Nominees currently oversee other registered investment companies advised by Cantor Fitzgerald Investment Advisors, L.P., an affiliate of O'Connor Alternative Investments that has been registered with the SEC as an investment adviser since 2011. The Trustee Nominees have been approved by the Boards, subject to election by each Fund's shareholders. The Boards have reviewed information provided by O'Connor Alternative Investments on the qualifications and backgrounds of the Trustee Nominees and, based on such information, believe that their election is in your best interest. If elected by shareholders of a Fund at the Special Meeting, the Trustee Nominees would take office effective as of a date shortly before the Closing Date, to provide sufficient time for the Trustee Nominees to consider and approve certain additional matters relating to the UBS/Cantor Transaction to take effect as of the Closing Date. The Current Trustees are not standing for election and will cease to serve as Trustees of each Trust effective when the Trustee Nominees take office. The election of the Trustee Nominees is subject to approval by the Fund's shareholders of the New Investment Management Agreement with O'Connor Alternative Investments.

It is important to note that, following the consummation of the UBS/Cantor Transaction, your Fund's current portfolio managers are expected to continue to manage your Fund and that the UBS/Cantor Transaction will not result in any change to your Fund's current investment objective, principal investment strategies and policies, principal risks, or fundamental and non-fundamental investment policies. In addition, the advisory fee rate payable by your Fund under the New Investment Management Agreement will be the same as the advisory fee rate payable under your Fund's Current Investment Management Agreement. Also, O'Connor Alternative Investments has represented that, subject to approval by the Trustee Nominees after they take office shortly before the Closing Date, it intends to enter into contractual expense limitation agreements, effective for a period of at least one year following the Closing Date of the UBS/Cantor Transaction, limiting each Fund's total net expenses (which agreements will permit such Funds to reimburse their investment adviser for advisory fees waived and/or expenses previously reimbursed under certain conditions) to the same levels as those expense levels provided under the current contractual expense limitation agreements between each Fund and UBS AM (Americas).

Your Board recommends that you vote "FOR" the proposals to approve the New Investment Management Agreement with O'Connor Alternative Investments and to elect the Trustee Nominees for your Fund.

Before you vote, we encourage you to read the full text of the enclosed joint proxy statement for an explanation of each of the proposals and information regarding important recent developments affecting the Funds.

Your vote on these matters is important. Even if you plan to attend and vote at the Special Meeting, please promptly follow the enclosed instructions to submit voting instructions by telephone or over the Internet. Alternatively, you may submit voting instructions by signing and dating each proxy card and returning it in the accompanying postage-paid return envelope. In order to ensure that shares will be voted in accordance with your instructions, please submit your proxy promptly.

If you have any questions about the proposals to be voted on, please call EQ Fund Solutions LLC at (877) 283-0322.

By Order of each Board,

IMPORTANT INFORMATION
FOR FUND SHAREHOLDERS

While we encourage you to read the full text of the enclosed Joint Proxy Statement, for your convenience, we have provided a brief overview of the proposals to be voted on.

Questions and Answers

Why am I receiving this Joint Proxy Statement?

A joint special meeting (the "Special Meeting") of shareholders of the funds listed below (each, a "Fund" and together, the "Funds") will be held on Monday, December 15, 2025 at 2:00 p.m., Eastern Time. You have received this letter because you were a shareholder of record of one of the Funds on October 10, 2025, the record date for the Special Meeting (the "Record Date"):

Credit Suisse Commodity Return Strategy Fund, a series of Credit Suisse Commodity Strategy Funds

Commodity Return Strategy Portfolio, a series of Credit Suisse Trust

Each of Credit Suisse Commodity Strategy Funds and Credit Suisse Trust (each, a "Trust") is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), and comprises one series as indicated above.

The enclosed Joint Proxy Statement describes a proposal to approve a new investment management agreement (the "New Investment Management Agreement") between each Trust, on behalf of its respective Fund, and O'Connor Alternative Investments, LLC ("O'Connor Alternative Investments") ("Proposal 1"). In addition, the enclosed Joint Proxy Statement includes a proposal to elect four nominees (collectively, the "Trustee Nominees") to each Trust's Board of Trustees (each, a "Board") to succeed the current members of the Trust's Board (the "Current Trustees") ("Proposal 2") (together with Proposal 1, the "Proposals").

Approval by one Fund's shareholders of the Proposals is not contingent upon shareholder approval of the Proposals by shareholders of the other Fund.

Shareholder approval of Proposal 2 to elect Trustee Nominees of a Fund is contingent upon shareholder approval of Proposal 1 to approve the New Investment Management Agreement for the Fund. Accordingly, if shareholders of a Fund do not approve the New Investment Management Agreement, then any shareholder approval of the Trustee Nominees for the Fund will be deemed null and the Fund's Board will then consider whether any other actions are warranted.

Who is asking for my vote?

The Board of your Fund is asking you to vote at the Special Meeting on the Proposals. Each Fund's Board approved the New Investment Management Agreement and nominated the Trustee Nominees for election to the Board as in the best interest of the Fund and its shareholders. For more information regarding the factors considered by the Boards in coming to these conclusions, please review the enclosed Joint Proxy Statement.

What am I being asked to vote "FOR" in this proxy?

You are being asked to vote in favor of each of Proposal 1 and Proposal 2.

Why am I being asked to vote on the Proposals?

You are being asked to approve a New Investment Management Agreement for your Fund as a result of a transaction involving UBS Asset Management (Americas) LLC ("UBS AM (Americas)"), each Fund's investment adviser.

On May 28, 2025, UBS AM (Americas) entered into a definitive agreement (the "Purchase Agreement") with O'Connor Alternative Investments pursuant to which O'Connor Alternative Investments, an indirect wholly owned subsidiary of Cantor Fitzgerald, L.P., will acquire UBS AM (Americas)'s O'Connor investment platform (the "UBS/Cantor Transaction"). As part of the UBS/Cantor Transaction, it is expected that the O'Connor investment management and support teams, which include each Fund's portfolio management team, will transition to O'Connor Alternative Investments, subject to certain conditions. The UBS/Cantor Transaction is expected to close with respect to the Funds during the first quarter of 2026 (the "Closing Date"). O'Connor Alternative Investments has no operating history and has recently registered with the SEC as an investment adviser.

It is proposed that O'Connor Alternative Investments succeed UBS AM (Americas) as your Fund's investment adviser in connection with the UBS/Cantor Transaction. Your Fund is subject to the Investment Company Act of 1940, as amended (the "1940 Act"), which requires the Funds' current investment management agreement with UBS AM (Americas) (the "Current Investment Management Agreement") to terminate automatically upon its "assignment." The Current Investment Management Agreement would therefore terminate automatically in the event it were assigned by UBS AM (Americas) to O'Connor Alternative Investments in connection with the UBS/Cantor Transaction. Accordingly, each Fund is seeking shareholder approval of the New Investment Management Agreement at the Special Meeting in connection with Proposal 1. If approved by shareholders, the New Investment Management Agreement would take effect as of the Closing Date.

At the Special Meeting, shareholders will also be asked to elect four Trustee Nominees to each Fund's Board to succeed the Current Trustees. The Trustee Nominees currently oversee other registered investment companies advised by Cantor Fitzgerald Investment Advisors, L.P., an affiliate of O'Connor Alternative Investments that has been registered with the SEC as an investment adviser since 2011. The Trustee Nominees have been approved by the Boards, subject to election by each Fund's shareholders. The Boards have reviewed information provided by O'Connor Alternative Investments on the qualifications and backgrounds of the Trustee Nominees and, based on such information, believe that their election is in your best interest. If elected by shareholders of a Fund at the Special Meeting, the Trustee Nominees would take office effective as of a date shortly before the Closing Date, to provide sufficient time for the Trustee Nominees to consider and approve certain additional matters relating to the UBS/Cantor Transaction to take effect as of the Closing Date. The Current Trustees are not standing for election and will cease to serve as Trustees of each Trust effective when the Trustee Nominees take office. The election of the Trustee Nominees is subject to approval by the Fund's shareholders of the New Investment Management Agreement.

How does the New Investment Management Agreement differ from the Current Investment Management Agreement?

The terms of the New Investment Management Agreement will be identical to those of the Current Investment Management Agreement, except for the investment adviser, dates of execution, effectiveness and termination and certain other non-material changes.

Will my Fund's contractual advisory fee rates go up?

No. Your Fund's contractual advisory fee rates will not change as a result of the New Investment Management Agreement.

Will any expense limitation agreements or advisory fee waivers for my Fund remain in place under my Fund's New Investment Management Agreement?

O'Connor Alternative Investments has represented that, subject to approval by the Trustee Nominees after they take office shortly before the Closing Date, it intends to enter into contractual expense limitation agreements, effective for a period of at least one year following the Closing Date of the UBS/Cantor Transaction, limiting each Fund's total net expenses (which agreements will permit such Funds to reimburse their investment adviser for advisory fees waived and/or expenses previously reimbursed under certain conditions) to the same levels as those expense levels provided under the current contractual expense limitation agreements between each Fund and UBS AM (Americas).

See "Proposal 1 - Approval of the New Investment Management Agreement" in the Joint Proxy Statement for additional information regarding the terms of your Fund's contractual expense limitation.

Will the New Investment Management Agreement result in any changes in the investment objective(s), principal investment strategies or portfolio managers of my Fund?

No changes to the investment objective, principal investment strategies and policies, principal risks, fundamental and non-fundamental investment policies, or portfolio managers of your Fund are currently contemplated as a result of the UBS/Cantor Transaction.

Who are the Trustee Nominees nominated to serve as Trustees of my Fund?

There are four Trustee Nominees for the election to the Board of your Fund: Douglas Barnard, Ramona Heine, Louis Zurita and William Ferri.

Mr. Barnard has almost a decade of experience as a Chief Financial Officer and has served as director of private funds and listed SPACs. Ms. Heine has over 20 years of experience in the fund and asset management industry. Mr. Zurita has over 30 years of experience owning, operating, acquiring, and developing commercial and residential real estate in the United States and the Caribbean. Mr. Ferri has over 25 years of experience as an executive in the asset management industry.

The Trustee Nominees have been approved by the Boards, subject to election by each Fund's shareholders. The Trustee Nominees currently oversee other registered investment companies advised by Cantor Fitzgerald Investment Advisors, L.P., an affiliate of O'Connor Alternative Investments. The Boards have reviewed information provided by O'Connor Alternative Investments on the qualifications and backgrounds of the Trustee Nominees and, based on such information, believe that their election is in your best interest.

When will the Trustee Nominees take office?

If elected by shareholders of a Fund at the Special Meeting, subject to shareholder approval of the New Investment Management Agreement, the Trustee Nominees would take office effective as of a date shortly before the Closing Date, to provide sufficient time for the Trustee Nominees to consider and approve certain additional matters relating to the UBS/Cantor Transaction to take effect as of the Closing Date. The Current Trustees are not standing for election and will cease to serve as Trustees of each Trust effective when the Trustee Nominees take office. The Current Trustees will work with Fund management on an orderly transition to the Trustee Nominees.

What is the required vote needed to approve each Proposal?

With respect to Proposal 1, approval of the New Investment Management Agreement will require the vote of a "majority of the outstanding voting securities" of the respective Fund entitled to vote on the applicable Proposal voting separately. A "majority of the outstanding voting securities" is defined in the 1940 Act as either (i) the vote of 67% or more of the voting securities entitled to vote on the applicable Proposal that are present at the Special Meeting, if the holders of more than 50% of the outstanding shares are present or represented by proxy, or (ii) the vote of more than 50% of the outstanding voting securities entitled to vote on the applicable Proposal, whichever is less.

Election of each Trustee Nominee in Proposal 2 requires a plurality of the votes cast at the Special Meeting by the shareholders of the respective Fund voting separately.

iii

Will there be any changes to my Fund's other service providers as a result of the UBS/Cantor Transaction?

No changes are expected with respect to the engagement of (i) State Street Bank and Trust Company ("State Street") as each Fund's custodian and co-administrator, (ii) SS&C Global Investor & Distribution Solutions, Inc. as each Fund's transfer agent, or (iii) Ernst & Young LLP as each Fund's independent registered public accounting firm, or the fees currently charged to the Funds by such service providers at this time. With respect to the Funds' other co-administrator, UBS AM (Americas) provides administrative services to each Fund under the Current Investment Management Agreement and is compensated for such services out of the Fund's advisory fee. Under the New Investment Management Agreement, O'Connor Alternative Investments will provide the same administrative services to each Fund currently provided by UBS AM (Americas) as co-administrator and will be compensated for such services out of the Fund's advisory fee, which is equal to the advisory fee currently charged to the Fund under the Current Investment Management Agreement. Subject to approval by the Trustee Nominees after they take office shortly before the Closing Date, it is currently expected that the Funds' distributor will change from UBS Asset Management (US) Inc. to Ultimus Fund Distributors, LLC, and the Funds' legal counsel will change from Simpson Thacher & Bartlett LLP to DLA Piper LLP and that the Funds will engage Northern Lights Compliance Services, LLC to provide certain compliance administrative services, in each case effective upon the Closing Date. These changes to certain Fund service providers do not require shareholder approval. Subject to any potential changes in fees not known at this time in connection with the anticipated service provider changes described above, the UBS/Cantor Transaction is not expected to establish a new fee or expense payable to your Fund service providers or increase any existing fee or expense to be paid by your Fund or its shareholders to your Fund service providers.

Have the Boards of my Fund approved the Proposals?

Yes, the Boards, including the Trustees who are not interested persons of the Fund (as defined in Section 2(a)(19) of the 1940 Act) (the "Independent Trustees"), have approved the Proposals.

What happens if the Proposals are not approved?

If your Fund's shareholders do not approve a Proposal, or if the UBS/Cantor Transaction does not close for any other reason, UBS AM (Americas) will remain investment adviser to each Fund and each Fund will continue to operate. The Current Trustees will consider other alternatives, including a new or modified request for shareholder approval of a new investment management agreement with O'Connor Alternative Investments, retaining a new investment adviser for your Fund (which also would need to be approved by shareholders of your Fund), or the possible liquidation and closing of your Fund. Accordingly, the Board urges you to vote without delay in order to avoid potential disruption to your Fund that could occur if shareholder approval is not obtained in that time.

In addition, if your Fund's shareholders do not approve the New Investment Management Agreement in Proposal 1, then any shareholder approval of the Trustee Nominees for the Fund in Proposal 2 will be deemed null and the Fund's Board will then consider whether any other actions are warranted.

Is my Fund paying for this proxy solicitation?

No. All costs of the proxy and the shareholder meetings, including proxy solicitation costs, legal fees and the costs of printing and mailing the proxy statement, will be borne equally by O'Connor Alternative Investments and UBS AM (Americas).

Will my vote make a difference?

Yes. Your vote is needed to ensure that the Proposals for your Fund can be acted upon. Your Fund's Board encourages you to participate in the governance of your Fund.

The Boards recommend that you vote "FOR" the Proposals to approve the New Investment Management Agreement with O'Connor Alternative Investments and elect the Trustee Nominees for your Fund.

Merely attending the Special Meeting, however, will not revoke any previously submitted proxy card.

Each of Credit Suisse Commodity Strategy Funds and Credit Suisse Trust is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), and comprises one series as indicated above. For purposes of this Joint Proxy Statement, the term "shareholder" (when used to refer to the beneficial holder of ownership interests in a Fund) also includes holders of variable annuity contracts and variable life insurance policies and participants in certain tax qualified pension and retirement plans.

OVERVIEW OF THE TRANSACTIONS AND THE PROPOSALS

On May 28, 2025, UBS AM (Americas), each Fund's investment adviser, entered into a definitive agreement (the "Purchase Agreement") with O'Connor Alternative Investments, LLC ("O'Connor Alternative Investments") pursuant to which O'Connor Alternative Investments, an indirect wholly owned subsidiary of Cantor Fitzgerald, L.P., will acquire UBS AM (Americas)'s O'Connor investment platform (the "UBS/Cantor Transaction"). As part of the UBS/Cantor Transaction, it is expected that the O'Connor investment management and support teams, which include each Fund's portfolio management team, will transition to O'Connor Alternative Investments, subject to certain conditions. The UBS/Cantor Transaction is expected to close with respect to the Funds during the first quarter of 2026 (the "Closing Date"). O'Connor Alternative Investments has no operating history and has recently registered with the SEC as an investment adviser.

As part of the UBS/Cantor Transaction, it is proposed that O'Connor Alternative Investments succeed UBS AM (Americas) as your Fund's investment adviser and the individuals who oversee other registered investment companies advised by Cantor Fitzgerald Investment Advisors, L.P., an affiliate of O'Connor Alternative Investments that has been registered with the SEC as an investment adviser since 2011 (collectively, the "Cantor Registered Funds"), succeed the current members of the Fund's Board (the "Current Trustees") as the Trustees of your Fund's Trust.

In connection with the change in investment adviser to the Funds, the Funds are seeking shareholder approval of a new investment management agreement between each Trust, on behalf of its respective Fund, with O'Connor Alternative Investments (the "New Investment Management Agreement") in connection with Proposal 1. Your Fund is subject to the Investment Company Act of 1940, as amended (the "1940 Act"), which requires the Funds' current investment management agreement with UBS AM (Americas) (the "Current Investment Management Agreement") to terminate automatically upon its "assignment." Your Fund's current investment management agreement would therefore terminate automatically in the event it were assigned by UBS AM (Americas) to O'Connor Alternative Investments in connection with the UBS/Cantor Transaction. Accordingly, each Fund is required to seek shareholder approval of the New Investment Management Agreement. The terms of the New Investment Management Agreement, including the advisory fee rate payable thereunder, will be identical to those of the Current Investment Management Agreement, except for the investment adviser, dates of execution, effectiveness and termination and certain other non-material changes. If approved by a Fund's shareholders, the New Investment Management Agreement will take effect with respect to such Fund as of the Closing Date.

To effectuate the change in the membership of each Fund's Board, shareholders are being asked to elect four nominees (collectively, the "Trustee Nominees") to each Fund's Board to succeed the Current Trustees in connection with Proposal 2. As noted above, the Trustee Nominees currently oversee the Cantor Registered Funds. If elected by shareholders of a Fund at the Special Meeting, the Trustee Nominees would take office effective as of a date shortly before the Closing Date, to provide sufficient time for the Trustee Nominees to consider and approve certain additional matters relating to the UBS/Cantor Transaction to take effect as of the Closing Date. The Current Trustees are not standing for election and will cease to serve as Trustees of each Trust effective when the Trustee Nominees take office.

Each Board has approved the following changes to the names of its respective Fund and Trust effective as of the Closing Date:

Current Fund and Trust Names

Post-Closing Fund and Trust Names

Credit Suisse Commodity Return Funds

Credit Suisse Commodity Return Strategy Fund

Cantor Fitzgerald Commodity Return Trust

Cantor Fitzgerald Commodity Return Strategy Fund

Credit Suisse Trust

Commodity Return Strategy Portfolio

Cantor Fitzgerald Variable Insurance Trust

Cantor Fitzgerald Commodity Return Strategy Portfolio

In addition to the proposed changes to the Trustees of each Board, subject to approval by the Trustee Nominees after they take office shortly before the Closing Date, it is expected that each of the Trusts' officers will change effective as of the Closing Date.

With respect to the Funds' other service providers, no changes are expected with respect to the engagement of (i) State Street Bank and Trust Company ("State Street") as each Fund's custodian and co-administrator, (ii) SS&C Global Investor & Distribution Solutions, Inc. as each Fund's transfer agent, or (iii) Ernst & Young LLP as each Fund's independent registered public accounting firm, or the fees currently charged to the Funds by such service providers at this time. With respect to the Funds' other co-administrator, UBS AM (Americas) provides administrative services to each Fund under the Current Investment Management Agreement and is compensated for such services out of the Fund's advisory fee. Under the New Investment Management Agreement, O'Connor Alternative Investments will provide the same administrative services to each Fund currently provided by UBS AM (Americas) as co-administrator and will be compensated for such services out of the Fund's advisory fee, which is equal to the advisory fee currently charged to the Fund under the Current Investment Management Agreement. Subject to approval by the Trustee Nominees after they take office shortly before the Closing Date, it is currently expected that the Funds' distributor will change from UBS Asset Management (US) Inc. to Ultimus Fund Distributors, LLC and the Funds' legal counsel will change from Simpson Thacher & Bartlett LLP to DLA Piper LLP and that the Funds will engage Northern Lights Compliance Services, LLC to provide certain compliance administrative services, in each case effective upon the Closing Date. These changes to certain Fund service providers do not require shareholder approval. Subject to any potential changes in fees not known at this time in connection with the anticipated service provider changes described above, the UBS/Cantor Transaction is not expected to establish a new fee or expense payable to your Fund service providers or increase any existing fee or expense to be paid by your Fund or its shareholders to your Fund service providers.

The Funds' current service providers and anticipated service providers following the Closing Date of the UBS/Cantor Transaction are set out below:

	Current Service Providers	Anticipated Service Providers Effective as of the Closing Date

Anticipated service provider change remains subject to approval by the Trustee Nominees after they take office shortly before the Closing Date.

Approval by one Fund's shareholders of the Proposals is not contingent upon shareholder approval of the Proposals by shareholders of the other Fund.

The foregoing is intended to provide a brief overview of the discussion of the Proposals that follows and is qualified in its entirety by such discussion.

PROPOSAL 1:

APPROVAL OF THE NEW INVESTMENT MANAGEMENT AGREEMENT BETWEEN EACH FUND AND O'CONNOR ALTERNATIVE INVESTMENTS

Each Trust is party, on behalf of its respective Fund, to the Investment Management Agreement dated as of September 26, 2023, as amended May 1, 2024 (the "Current Investment Management Agreement"). Under the Current Investment Management Agreement, UBS AM (Americas) acts as the investment adviser to each Fund. The Current Investment Management Agreement was last approved by each Fund's Board, including a majority of the Trustees who are not "interested persons" (as defined in the 1940 Act) of any party to such agreement (collectively, the "Independent Trustees"), at an in-person meeting held on November 11 and 12, 2024. Effective May 1, 2024, the Board approved the amendment of the Current Investment Management Agreement to reflect UBS AM (Americas) as the investment adviser to the Funds following the merger of Credit Suisse Asset Management, LLC ("CSAM"), each Fund's prior investment adviser, into UBS AM (Americas) effective as of May 1, 2024, with UBS AM (Americas) surviving and succeeding as investment adviser to the Funds. The Current Investment Management Agreement was most recently submitted to a vote of, and approved by, each Fund's shareholders on August 24, 2023 in connection with the merger of Credit Suisse Group AG ("CS Group") with and into UBS Group AG, with UBS Group AG as the surviving company, on June 12, 2023, which was deemed to result in an "assignment" and the automatic termination of each Fund's prior investment management agreement with CSAM under the terms of such agreement and the 1940 Act.

The Current Investment Management Agreement provides that such agreement would automatically terminate in the event of its assignment, as required by Section 15(a) of the 1940 Act. An "assignment" of an investment management agreement includes a direct transfer or hypothecation of the agreement as well as a direct or indirect transfer of a controlling block of the investment adviser's outstanding voting securities (sometimes referred to as a "change of control"). The Current Investment Management Agreement would therefore terminate automatically in the event it were assigned by UBS AM (Americas) to O'Connor Alternative Investments in connection with the UBS/Cantor Transaction.

To transition investment management of the Funds from UBS AM (Americas) to O'Connor Alternative Investments, we are asking shareholders of each Fund in Proposal 1 to approve the New Investment Management Agreement. A copy of the New Investment Management Agreement is attached in Appendix A.

At a meeting held on October 6, 2025 (the "October 6, 2025 Board Meeting"), in anticipation of the closing of the UBS/Cantor Transaction, each Board, including a majority of Independent Trustees, approved the New Investment Management Agreement between each Trust, on behalf of its respective Fund, and Cantor. The New Investment Management Agreement, as approved by the Board, is submitted for approval by the shareholders of each Fund and must be voted upon separately by shareholders of that Fund who held shares of the Fund as of the Record Date.

Shareholder approval of Proposal 1 by one Fund is not contingent upon shareholder approval of Proposal 1 by the other Fund. Accordingly, if a Fund's shareholders approve the New Investment Management Agreement with respect to that Fund, it will go into effect on the Closing Date of the UBS/Cantor Transaction. If shareholders of a Fund do not approve Proposal 1, the Board of that Fund will then consider whether other actions, if any, are warranted, including a new or modified request for shareholder approval of a new investment management agreement with O'Connor Alternative Investments, retaining a new investment adviser for your Fund (which also would need to be approved by shareholders of your Fund), or the possible liquidation and closing of your Fund.

It is important to note that, following the consummation of the UBS/Cantor Transaction, your Fund's current portfolio managers are expected to continue to manage your Fund and that the UBS/Cantor Transaction will not result in any change to your Fund's current investment objective, principal investment strategies and policies, principal risks, or fundamental and non-fundamental investment policies. In addition, the advisory fee rate payable by your Fund under the New Investment Management Agreement will be the same as the advisory fee rate payable under your Fund's Current Investment Management Agreement. Also, O'Connor Alternative Investments has represented that, subject to approval by the Trustee Nominees after they take office shortly before the Closing Date of the UBS/Cantor Transaction, it intends to enter into contractual expense limitation agreements, effective for a period of at least one year following the Closing Date of the UBS/Cantor Transaction, limiting each Fund's total net expenses (which agreements will permit such Funds to reimburse their investment adviser for advisory fees waived and/or expenses previously reimbursed under certain conditions) to the same levels as those expense levels provided under the current contractual expense limitation agreements between each Fund and UBS AM (Americas).

As discussed above, in connection with the New Investment Management Agreement, O'Connor Alternative Investments proposed to change the members of the Board to the individuals who oversee the Cantor Registered Funds in connection with the UBS/Cantor Transaction. See "Proposal 2 - Election of Trustee Nominees."

Comparison of the Current Investment Management Agreement and the New Investment Management Agreement

The terms of the New Investment Management Agreement are identical to the terms of the Current Investment Management Agreement, except for the investment adviser, the dates of execution, effectiveness and termination and certain non-material changes. The Current Investment Management Agreement had, and the corresponding New Investment Management Agreement has, an initial period of two years and thereafter shall continue automatically for successive annual periods, provided such continuance is specifically approved at least annually by (a) the Board of the respective Fund or (b) a vote of a "majority of the outstanding voting securities" of the Fund (as defined in the 1940 Act), provided that in either event the continuance is also approved by a majority of the Independent Trustees, by vote cast in person at a meeting called for the purpose of voting on such approval.

Under the Current Investment Management Agreement, the annual advisory fee rate payable by each Fund is equal to 0.59% of the average daily net assets of such Fund. Under the New Investment Management Agreement, the advisory fee rates payable by the Funds will be the same as those under the Current Investment Management Agreement.

Both the Current Investment Management Agreement and the New Investment Management Agreement may be terminated with respect to a Fund at any time without the payment of any penalty, upon 60 days' written notice to the applicable investment adviser by the Board or by a vote of the majority of the respective Fund's outstanding voting securities. Both the Current Investment Management Agreement and the New Investment Management Agreement may be terminated by the applicable investment adviser on 90 days' written notice to the respective Fund. Both the Current Investment Management Agreement and the New Investment Management Agreement will also terminate automatically in the event of its "assignment" (as defined in the 1940 Act).

Board Review and Approval of the New Investment Management Agreement

As noted above, each Board, including a majority of the Independent Trustees of such Board, approved the New Investment Management Agreement at the October 6, 2025 Board Meeting after concluding that the approval of the New Investment Management Agreement was in the best interests of its respective Fund and Fund shareholders. The factors considered by each Board in considering and approving the New Investment Management Agreement are set out below.

Each Board, including the Independent Trustees, were assisted by experienced independent legal counsel throughout the New Investment Management Agreement review process. The Independent Trustees discussed the proposed approvals in private session with such counsel at which no representatives of O'Connor Alternative Investments or UBS AM (Americas) were present.

In anticipation of the closing of the UBS/Cantor Transaction and in response to a request from the Current Trustees, the Current Trustees met with representatives of O'Connor Alternative Investments at the Boards' quarterly meeting held on August 12, 2025, who provided information regarding the Cantor Fitzgerald asset management business and the investment advisory services expected to be provided to the Cantor Registered Funds. The Current Trustees also met with the Trustee Nominees on September 16, 2025 and certain officers of O'Connor Alternative Investments and the Cantor Registered Funds on September 26, 2025. The Boards also received regular updates from representatives of UBS AM (Americas), including the Funds' portfolio management team, on the UBS/Cantor Transaction and the plans to transition the management of the Funds at special meetings following the announcement of the UBS/Cantor Transaction (such special meetings collectively with the August 12, 2025, September 16, 2025 and September 26, 2025 meetings and the October 6, 2025 Board Meeting, the "Meetings").

At the Meetings, representatives of UBS AM (Americas) and O'Connor Alternative Investments, as the case may be, responded to questions from the Boards, and discussed, among other things, the strategic rationale for the UBS/Cantor Transaction and O'Connor Alternative Investments' general plans and intentions regarding the Funds. Each Board, including the Independent Trustees, evaluated the terms of the New Investment Management Agreement, reviewed the information provided by O'Connor Alternative Investments in connection with the consideration of approving the New Investment Management Agreement on behalf of the Funds, and reviewed the duties and responsibilities of the Board in evaluating and approving the New Investment Management Agreement.

In connection with each Board's review of the New Investment Management Agreement, O'Connor Alternative Investments and UBS AM (Americas) advised the Board about a variety of matters, including the following:

●

The services to be provided to the Funds under the New Investment Management Agreement will be identical to those services provided under the Current Investment Management Agreement.

●

All of the portfolio management personnel who currently manage the Funds are expected to move to O'Connor Alternative Investments and continue to manage the Funds under the New Investment Management Agreement. In addition, certain other personnel of UBS AM (Americas) who currently provide services to the Funds are expected to move to O'Connor Alternative Investments.

●

There would be no changes to each Fund's current investment objective, principal investment strategies and policies, principal risks, or fundamental and non-fundamental investment policies in connection with the UBS/Cantor Transaction.

In addition to the information provided by O'Connor Alternative Investments and UBS (AM) Americas representatives as described above, the Boards also considered, among other factors, the following:

●

The reputation, financial statements, and resources of O'Connor Alternative Investments and its affiliates, including Cantor Fitzgerald Investment Advisors, L.P., and the potential benefits to shareholders of retaining O'Connor Alternative Investments as investment adviser to the Funds, including anticipated continuity of portfolio management.

●

Although O'Connor Alternative Investments is a newly formed and registered investment adviser, Cantor Fitzgerald Investment Advisors, L.P., an affiliate of O'Connor Alternative Investments, has been registered with the SEC as an investment adviser since 2011.

●

Cantor Fitzgerald Investment Advisors, L.P.'s and the Trustee Nominees' experience with past acquisitions of funds.

●

The terms and conditions of the New Investment Management Agreement, including that each Fund's contractual advisory fee rates under the New Investment Management Agreement will remain the same.

●

The capabilities, resources, and personnel of O'Connor Alternative Investments necessary to provide the investment management services currently provided to each Fund, and the transition and integration plans for the Funds.

●

The advisory fees to be paid by each Fund under the New Investment Management Agreement represent reasonable compensation to O'Connor Alternative Investments in light of the services to be provided, the costs to O'Connor Alternative Investments of providing those services, economies of scale, and the fees and other expenses paid by similar funds (based on information compiled by O'Connor Alternative Investments from an unaffiliated third-party proprietary database) and such other matters that each Board considered relevant in the exercise of its reasonable judgment.

●

O'Connor Alternative Investments and UBS AM (Americas) have agreed to pay all expenses of the Funds in connection with this proxy solicitation, and the Funds will bear no costs in obtaining shareholder approval of the New Investment Management Agreement or the election of the Trustee Nominees.

In considering whether to approve the New Investment Management Agreement on behalf of the Funds, the Boards reviewed the materials provided for the October 6, 2025 Board Meeting, including: (i) a copy of the form of New Investment Management Agreement; (ii) information describing the nature, quality and extent of the services that O'Connor Alternative Investments expects to provide to the Funds; and (iii) information concerning the financial condition, business, operations and compliance program of O'Connor Alternative Investments and its affiliate, Cantor Fitzgerald Investment Advisors, L.P.

Investment Advisory Fee Rates and Expenses

Each Board reviewed and considered the contractual advisory fee rate of 0.59% of its respective Fund's average daily net assets (the "Contractual Advisory Fee") to be payable by the Fund under the New Investment Management Agreement in light of the extent and quality of the management services to be provided by O'Connor Alternative Investments, each Fund's proposed investment manager following the Closing Date of the UBS/Cantor Transaction. The Boards also considered that O'Connor Alternative Investments has represented that, subject to approval by the Trustee Nominees after they take office shortly before the Closing Date, it intends to enter into contractual expense limitation agreements, effective for a period of at least one year following the Closing Date, limiting each Fund's total net expenses (which agreements will permit such Funds to reimburse their investment adviser for advisory fees waived and/or expenses previously reimbursed under certain conditions) to the same levels as those expense levels provided under the current contractual expense limitation agreements between each Fund and UBS AM (Americas), which are, in the case of Credit Suisse Commodity Return Strategy Fund, 1.05%, 1.80% and 0.80% of the average daily net assets of Class A shares, Class C shares and Class I shares, respectively, and, in the case of Commodity Return Strategy Portfolio, 1.05% and 0.80% of the average daily net assets of Class 1 shares and Class 2 shares, respectively.

Additionally, the Boards received and considered information comparing each Fund's Contractual Advisory Fee, Contractual Advisory Fee less waivers and/or reimbursements ("Net Advisory Fee") and overall expenses with those of the funds in the relevant peer group (the "Peer Group") provided by Morningstar, Inc., an independent provider of investment company data. The Boards noted O'Connor Alternative Investments' observations that the Funds' Contractual Advisory Fees are below the average of the Peer Group and that the expense ratios of the Class C shares and Class I shares of Credit Suisse Commodity Return Strategy Fund were competitive with or below the average, respectively, of the Peer Group and the expense ratios of the Class 1 shares and Class 2 shares of Commodity Return Strategy Portfolio were competitive with or below the average, respectively, of the Peer Group.

Nature, Extent and Quality of the Services under the New Investment Management Agreement

The Boards received and considered information regarding the nature, extent and quality of services to be provided to each Fund by O'Connor Alternative Investments under the New Investment Management Agreement. The Boards also noted information received at the Meetings related to the services to be rendered by O'Connor Alternative Investments which, in addition to portfolio management and investment management services set forth in the New Investment Management Agreement, included credit analysis and research, supervising the day-to-day operations of the Fund's non-advisory functions, which include accounting, administration, custody, transfer agent and other applicable third-party service providers; overseeing and facilitating audits; and supervising and/or preparing applicable Fund filings, disclosures and shareholder reports. The Boards noted that the extensive investment management services to be provided by O'Connor Alternative Investments included broad supervisory responsibility and oversight over other service providers to the Fund. The Boards also considered O'Connor Alternative Investment's anticipated compliance program with respect to the Fund. The Board reviewed background information about O'Connor Alternative Investments including its Form ADV Part 2A - Disclosure Brochure. The Boards considered the background and experience of O'Connor Alternative Investments' senior management and the expertise of, and the amount of attention expected to be given to each Fund by senior personnel of O'Connor Alternative Investments. In addition, each Board reviewed the qualifications, backgrounds and responsibilities of its respective Fund's portfolio management team primarily responsible for the day-to-day portfolio management of the Fund, noting that the members the Fund's portfolio management team will move from UBS AM (Americas) to O'Connor Alternative Investments, and the extent of the resources expected to be devoted to research and analysis of actual and potential investments, as well as the resources expected to be provided to them. The Boards evaluated the ability of O'Connor Alternative Investments, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory, and supervisory personnel.

Fund Performance

The Boards received and considered information comparing each Fund's performance results over the previous year ended September 3, 2025, as well as over the one-month, three-month, and six-month, three-, five- and ten-year, and calendar year-to-date periods ended September 3, 2025, with the performance of the funds in the Peer Group for the same periods.

Each Board also considered the investment performance of its respective Fund relative to its stated objectives.

Investment Manager Profitability

The Boards received and considered a profitability analysis of O'Connor Alternative Investments based on the fees to be payable under the New Investment Management Agreement for the Funds, including any fee waivers, as well as other relationships between the Funds on the one hand and affiliates of O'Connor Alternative Investments on the other. The Board deliberations also reflected, in the context of O'Connor Alternative Investments' profitability, O'Connor Alternative Investments' methodology for allocating costs to the Funds, recognizing that cost allocation methodologies are inherently subjective. The Boards also reviewed O'Connor Alternative Investments' anticipated profit margin as reflected in the profitability analysis, as well as reviewing profitability in light of appropriate court cases and the services rendered to the Fund.

Economies of Scale

The Boards considered information regarding whether there are expected to be economies of scale with respect to the management of each Fund by O'Connor Alternative Investments. The Boards noted that, if the Funds' asset levels grow, further economies of scale potentially could be realized (although this is not guaranteed) and also noted the expense limitation agreements anticipated to be in place between each Fund and O'Connor Alternative Investments for a period of at least one year following the Closing Date of the UBS/Cantor Transaction. The Boards received information regarding O'Connor Alternative Investments' projected profitability in connection with providing investment management services to the Fund, including O'Connor Alternative Investments' costs in providing the services.

Other Benefits to O'Connor Alternative Investments

The Boards considered other benefits expected to be received by O'Connor Alternative Investments and its affiliates as a result of their relationship with the Funds. Such benefits include, among others, benefits potentially derived from an increase in O'Connor Alternative Investments' and its affiliates' businesses and their reputation as a result of their relationship with the Funds.

The Boards considered the standards O'Connor Alternative Investments expects to apply in seeking best execution and O'Connor Alternative Investments' expected policies and practices regarding soft dollars for the Funds, and reviewed O'Connor Alternative Investments' anticipated method for allocating portfolio investment opportunities among its advisory clients.

Other Factors and Broader Review

As discussed above, the Boards reviewed detailed materials received from O'Connor Alternative Investments as part of the approval process and also considered the information discussed with the Boards during the Meetings.

Conclusions

In selecting O'Connor Alternative Investments, and approving the New Investment Management Agreement with respect to each Fund and the investment advisory fee under such agreement, each Board concluded, on behalf of its respective Fund, that:

●

The Contractual Advisory Fee and Net Advisory Fee, reviewed along with information provided by Broadridge for the funds in the Fund's Expense Group and Expense Universe, were reasonable in relation to the services expected to be provided by O'Connor Alternative Investments.

●

The Board was satisfied with the nature, extent and quality of the investment management services expected to be provided to the Fund by O'Connor Alternative Investments in a challenging commodities environment and that, based on dialogue with representatives of O'Connor Alternative Investments and counsel, the services expected to be provided by O'Connor Alternative Investments under the New Investment Management Agreement are typical of, and consistent with, those provided to similar mutual funds by other investment managers.

●

In light of the costs of providing investment management and other services to the Fund and O'Connor Alternative Investments' commitment to the Fund and willingness to waive fees (by agreeing to a contractual expense limitation, subject to approval by the Trustee Nominees after they take office shortly before the Closing Date), O'Connor Alternative Investments' anticipated net profitability based on fees payable under the New Investment Management Agreement, as well as other ancillary benefits that O'Connor Alternative Investments and its affiliates expect to receive, were considered reasonable.

●

In light of the information received and considered by the Board, the Fund's current fee structure was considered reasonable.

No single factor reviewed by each Board was identified by the Board as the principal factor in determining whether to approve the New Investment Management Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.

Recommendation of the Boards

Each Board recommends that shareholders of its Fund vote "FOR" Proposal 1.

PROPOSAL 2: ELECTION OF TRUSTEE NOMINEES

In connection with the change in the Funds' investment adviser from UBS AM (Americas) to O'Connor Alternative Investments, at the October 6, 2025 Board Meeting, the Board considered and approved a proposal to change the composition of the Board from the Current Trustees to the Trustee Nominees. The Trustee Nominees currently do not serve on the Boards of the Trusts; however, the Trustee Nominees currently oversee the Cantor Registered Funds, which are advised by Cantor Fitzgerald Investment Advisors, L.P., an affiliate of O'Connor Alternative Investments. The Trustee Nominees have been approved by the Boards, subject to election by each Fund's shareholders. The Boards have reviewed information provided by O'Connor Alternative Investments on the qualifications and backgrounds of the Trustee Nominees in advance of the October 6, 2025 Board Meeting and met with the Trustee Nominees on September 16, 2025 to discuss such matters. Based on such information, the Boards believe that the election of the Trustee Nominees is in your best interest. Each of the Trustee Nominees was recommended for nomination for election by the Nominating Committee of each Board.

The Trustee Nominees for election to the Boards are Douglas Barnard, Ramona Heine, Louis Zurita and William Ferri. The Trustee Nominees currently do not serve on the Board of the Funds, however, each Trustee Nominee currently serves on the boards of the Cantor Registered Funds.

Each of Ms. Heine and Messrs. Barnard and Zurita is not expected to be an "interested person" of each Fund (each, an "Independent Trustee Nominee"), as that term is defined in Section 2(a)(19) of the 1940 Act, effective as of the Closing Date. Mr. Ferri is expected to be an "interested person" of each Fund (the "Interested Trustee Nominee") effective as of the Closing Date because of his position with O'Connor Alternative Investments.

If elected by shareholders of a Fund, the Trustee Nominees would succeed the Current Trustees and take office effective as of a date shortly before the Closing Date, to provide sufficient time for the Trustee Nominees to consider and approve certain additional matters relating to the UBS/Cantor Transaction to take effect as of the Closing Date. The Current Trustees are not standing for election and will cease to serve as Trustees of each Trust effective when the Trustee Nominees take office. Each Trustee Nominee elected at the Special Meeting will serve for a term of indefinite duration until his or her successor is duly elected and qualifies, or his or her earlier death, resignation or retirement. It is the intention of the persons named as proxies in the accompanying proxy card to nominate and vote in favor of each Trustee Nominee listed below for election as a Trustee of each Trust.

Each of the Trustee Nominees has consented to serve as a Trustee. The Boards know of no reason why any of the Trustee Nominees will be unable to serve, but in the event any Trustee Nominee is unable to serve or for good cause will not serve, the proxies received indicating a vote in favor of such Trustee Nominee will be voted for a substitute nominee as each Board may recommend.

An Independent Trustee Nominee is any Nominee that is an "interested person" of each Fund within the meaning of Section 2(a)(19) of the 1940 Act.

(4)

The Interested Trustee Nominee is a Nominee that is expected to be an "interested person" of each Fund within the meaning of Section 2(a)(19) of the 1940 Act. Mr. Ferri is expected to be an "interested person" of each Fund effective upon the Closing Date by virtue of his current position with O'Connor Alternative Investments, the proposed investment adviser to the Funds.

Qualifications of Trustee Nominees

Each Trustee Nominee was nominated by the Boards to succeed the Current Trustees in connection with the UBS/Cantor Transaction based on a variety of factors, none of which, by itself, was a controlling factor. The Board has concluded, based on each Trustee Nominee's experience, qualifications, attributes or skills, on an individual basis and in combination with those of other Trustee Nominees, that each Trustee Nominee is qualified to serve as a Trustee of each Fund. Among the attributes common to all the Trustee Nominees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with other trustees, the Funds' investment adviser, counsel, the independent registered public accounting firm and other service providers, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee Nominee's ability to perform his or her duties effectively may have been attained through the Trustee Nominee's business, consulting, public service and/or academic positions; experience from service as a trustee of the Cantor Registered Funds, other mutual funds, public companies, non-profit entities or other organizations; educational background or professional training; and/or other life experiences. In addition to these shared characteristics, set forth below is a brief discussion of the specific experience, qualifications, attributes or skills of each Trustee Nominee.

Independent Trustee Nominees

Douglas Barnard. Mr. Barnard has almost a decade of experience as a Chief Financial Officer and has served as director of private funds and listed SPACs.

Ramona Heine. Ms. Heine has over 20 years of experience in the fund and asset management industry.

Louis Zurita. Mr. Zurita has over 30 years of experience owning, operating, acquiring, and developing commercial and residential real estate in the United States and the Caribbean.

Interested Trustee Nominee

William Ferri. Mr. Ferri has over 25 years of experience as an executive in the asset management industry.

Specific details regarding each Trustee Nominee's principal occupations during the past five years are included in the table above.

Ownership of Fund Shares

As of August 31, 2025, the Trustee Nominees did not beneficially own any equity securities of the Funds.

Ownership in Certain Entities

As of August 31, 2025, no Independent Trustee Nominee, or his or her immediate family members, owned an interest, beneficially or of record, UBS AM (Americas), each Fund's current investment adviser, O'Connor Alternative Investments, each Fund's proposed investment adviser effective upon the Closing Date, UBS Asset Management (US) Inc. ("UBS AM (US)"), each Fund's current distributor, Ultimus Fund Distributors, LLC, each Fund's anticipated distributor effective upon the Closing Date (subject to approval by the Trustee Nominees), or a person (other than a registered investment company) directly or indirectly controlling, controlled by, or under common control with such entities, as applicable.

None of the Trustee Nominees has purchased or sold securities in an amount exceeding one percent of any class of securities of UBS AM (Americas) or O'Connor Alternative Investments, or either investment adviser's parents or subsidiaries, since the beginning of the fiscal year ended October 31, 2024, in the case of Credit Suisse Commodity Return Strategy Fund, and the fiscal year ended December 31, 2024, in the case of Commodity Return Strategy Portfolio.

Compensation of Trustees

Effective January 1, 2025, each Trustee who is not a director, trustee, officer or employee of UBS AM (Americas), State Street, UBS AM (US) or any of their affiliates receives an annual retainer of $110,000 for the open-end fund complex for four quarterly meetings and one special meeting and is reimbursed for expenses incurred in connection with his or her attendance at Board meetings. Trustee compensation is paid proportionately by all open-end funds in the Fund Complex, among them the Funds, which pay only their proportionate share as set forth in Appendix C. The Independent Chair of the open-end fund complex receives an aggregate annual fee of $24,047 and the chairman of the Audit Committee of the open-end fund complex receives an additional $9,783 in the aggregate and the chair of the Nominating Committee of the open-end fund complex receives an additional $5,357 in the aggregate. Prior to January 1, 2024, each Trustee received an annual retainer of $105,000.

The Trustee Nominees were not paid any compensation by each Fund for the Fund's most recent fiscal year.

The Current Trustees have not approved any changes to the compensation structure of the Boards described above in connection with the UBS/Cantor Transaction. However, the Current Trustees are not standing for election and will cease to serve as Trustees of each Trust effective when the Trustee Nominees take office. It is expected that the Trustee Nominees, if elected by shareholders, will determine to alter the compensation structure of each Board when they take office shortly before the Closing Date.

Leadership Structure and Oversight Responsibilities of the Board

Overall responsibility for oversight of each Fund rests with the applicable Board. Each Fund has engaged UBS AM (Americas) to manage the Fund on a day-to day basis. The applicable Board is responsible for overseeing UBS AM (Americas) and other service providers in the operations of the Fund in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Fund's charter. Each Board is currently composed of four members, each of whom is a Trustee, who is not an "interested person" of the Fund as defined in the 1940 Act ("Independent Trustee"). Each Board meets in-person at regularly scheduled quarterly meetings each year. In addition, each Board may hold special in-person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. As described below, each Board has established a Nominating Committee and an Audit Committee, and may establish ad hoc committees or working groups from time to time, to assist the Board in fulfilling its oversight responsibilities. The Independent Trustees also have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Each Board has appointed Laura A. DeFelice, an Independent Trustee, to serve in the role of Chair of the Board. The Chair's role is to preside at all meetings of the Board and to act as a liaison with UBS AM (Americas), counsel and other Trustees generally between meetings. The Chair serves as a key point person for dealings between management and the Trustees. The Chair also may perform such other functions as may be delegated by the Board from time to time.

Ms. DeFelice will cease to serve as the Chair of each Board when the Trustee Nominees take office shortly before the Closing Date. Accordingly, the Trustee Nominees will be required to alter the leadership structure of each Board when they take office shortly before the Closing Date.

Each Board reviews matters related to its leadership structure annually. Each Board has determined that the Board's leadership structure is appropriate because it allows the Board to exercise informed and independent judgment over the matters under its purview and it allocates areas of responsibility among committees of Trustees and the full Board in a manner that enhances effective oversight.

The Funds are subject to a number of risks, including investment, compliance, operational and valuation risks, among others. Risk oversight forms part of each Board's general oversight of the Fund and is addressed as part of various Board and committee activities. Day-to-day risk management functions are subsumed within the responsibilities of UBS AM (Americas), and other service providers (depending on the nature of the risk), which carry out the Funds' investment management and business affairs. UBS AM (Americas), and other service providers employ a variety of processes, procedures and controls to identify various events or circumstances that give rise to risks, to lessen the probability of their occurrence and/or to mitigate the effects of such events or circumstances if they do occur. Each of UBS AM (Americas) and other service providers have their own independent interest in risk management, and their policies and methods of risk management will depend on their functions and business models. Each Board recognizes that it is not possible to identify all of the risks that may affect the Fund or to develop processes and controls to eliminate or mitigate their occurrence or effects. As part of its regular oversight of the Fund, each Board interacts with and reviews reports from, among others, UBS AM (Americas), the Fund's Chief Compliance Officer, the Fund's independent registered public accounting firm and counsel, as appropriate, regarding risks faced by the Fund and applicable risk controls. Each Board may, at any time and in its discretion, change the manner in which it conducts risk oversight.

The Board of Credit Suisse Commodity Strategy Funds met eleven times during the fiscal year ended October 31, 2024. The Board of Credit Suisse Trust met ten times during the fiscal year ended December 31, 2024.

Each Current Trustee then in office attended at least 75% of the total number of meetings that each Board held during the Fund's respective fiscal year and, if a member, at least 75% of the total number of meetings of the committees held during the Fund's respective fiscal year.

Committees of the Board and Committee Meetings

Each Fund has an Audit Committee and a Nominating Committee. The members of the Audit Committee and the Nominating Committee consist of all the Independent Trustees, namely Messrs. Gupta and Shaiman and Mses. DeFelice and Kappagoda.

In accordance with its written charter adopted by its Board, each Audit Committee (a) assists Board oversight of the integrity of the Fund's financial statements, the independent registered public accounting firm's qualifications and independence, the Fund's compliance with legal and regulatory requirements and the performance of the Fund's independent registered public accounting firm; (b) prepares an audit committee report, if required by the SEC, to be included in the Fund's annual proxy statement, if any; (c) oversees the scope of the annual audit of the Fund's financial statements, the quality and objectivity of the Fund's financial statements, the Fund's accounting and financial reporting policies and its internal controls; (d) determines the selection, appointment, retention and termination of the Fund's independent registered public accounting firm, as well as approving the compensation thereof; (e) pre-approves all audit and non-audit services provided to the Fund and certain other persons by such independent registered public accounting firm; and (f) acts as a liaison between the Fund's independent registered public accounting firm and the full Board. The Audit Committee of the Board of Credit Suisse Commodity Strategy Funds met six times during the fiscal year ended October 31, 2024, and the Audit Committee of the Board of Credit Suisse Trust met five times during the fiscal year ended December 31, 2024.

In accordance with its written charter adopted by its Board, a copy of which is included in Appendix B, each Nominating Committee recommends to the Board persons to be nominated by the Board for election at the Fund's meetings of shareholders, special or annual, if any, or to fill any vacancy on the Board that may arise between shareholder meetings. Each Nominating Committee also makes recommendations with regard to the tenure of Board members and is responsible for overseeing an annual evaluation of the Board and its committee structure to determine whether such structure is operating effectively. The Nominating Committee of the Board of Credit Suisse Commodity Strategy Funds met seven times during the fiscal year ended October 31, 2024, and the Nominating Committee of the Board of Credit Suisse Trust met four times during the fiscal year ended December 31, 2024.

Each Nominating Committee will consider for nomination to the Board candidates submitted by the Fund's shareholders or from other sources it deems appropriate. Any recommendation should be submitted to the Fund's Secretary, c/o UBS Asset Management (Americas) LLC, Eleven Madison Avenue, New York, NY 10010. Any submission should include at a minimum the following information: the name, age, business address, residence address and principal occupation or employment of such individual, the class, series and number of shares of the Fund that are beneficially owned by such individual, the date such shares were acquired and the investment intent of such acquisition, whether such shareholder believes such individual is, or is not, an "interested person" of the Fund (as defined in the 1940 Act), and information regarding such individual that is sufficient, in the Committee's discretion, to make such determination, and all other information relating to such individual that is required to be disclosed in solicitation of proxies for election of trustees in an election contest (even if an election contest is not involved) or is otherwise required pursuant to the rules for proxy materials under the Exchange Act. If the Fund is holding a shareholder meeting, any such submission, in order to be included in the Fund's proxy statement, should be made no later than the 120th calendar day before the date the Fund's proxy statement was released to security holders in connection with the previous year's annual meeting or, if the Fund has changed the meeting date by more than 30 days or if no meeting was held the previous year, within a reasonable time before the Fund begins to print and mail its proxy statement.

The Current Trustees have not approved any changes to the committee structure of the Boards described above in connection with the UBS/Cantor Transaction. However, the Current Trustees are not standing for election and will cease to serve as Trustees of each Trust effective when the Trustee Nominees take office. Accordingly, the Trustee Nominees, if elected by shareholders, will be required to alter the committee structure of each Board when they take office shortly before the Closing Date.

Current Trustees, Advisory Board Member and Officers of the Funds

The name, address, position and principal occupations during the past five years of the Current Trustees, Advisory Board Member and principal executive officers of the Funds, a discussion of the qualifications of the Current Trustees and Advisory Board Member, and the compensation of the Current Trustees and the Advisory Board Member are set out in Appendix C.

Recommendation of the Boards

Each Board recommends that shareholders of its Fund vote "FOR" Proposal 2.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

On April 23, 2024, each Fund's Board approved the dismissal of PricewaterhouseCoopers LLP ("PwC") as the independent registered public accounting firm for the Funds, due to PwC's ceasing to be deemed an independent registered public accounting firm with respect to the Funds after April 30, 2024. Each Board's decision to approve the dismissal of PwC was recommended by the Audit Committee of the Board. PwC's reports on the Funds' financial statements for the fiscal periods ended October 31, 2023 and October 31, 2022, in the case of Credit Suisse Commodity Return Strategy Fund, and for the fiscal periods ended December 31, 2023 and December 31, 2022, in the case of Commodity Return Strategy Portfolio, contained no adverse opinion or disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope or accounting principle. During each Fund's fiscal periods ended October 31, 2023 and October 31, 2022, in the case of Credit Suisse Commodity Return Strategy Fund, and December 31, 2023 and December 31, 2022, in the case of Commodity Return Strategy Portfolio, and the subsequent interim periods through April 23, 2024, (i) there were no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC, would have caused them to make reference to the subject matter of the disagreements in connection with their reports on the Fund's financial statements for such periods, and (ii) there were no "reportable events" of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended.

Effective June 19, 2024, Ernst & Young LLP ("EY") was engaged as the independent registered public accounting firm following the recommendation of the Audit Committee of each Fund's Board and approval by each Fund's Board for the fiscal year ended October 31, 2024, in the case of Credit Suisse Commodity Return Strategy Fund, and the fiscal year ended December 31, 2024, in the case of Commodity Return Strategy Portfolio. During the Fund's fiscal periods ended October 31, 2023 and October 31, 2022, in the case of Credit Suisse Commodity Return Strategy Fund, and December 31, 2023 and December 31, 2022, in the case of Commodity Return Strategy Portfolio, and the subsequent interim periods through June 19, 2024, neither Fund, nor anyone on its behalf, consulted with EY on items which: (i) concerned the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Fund's financial statements; or (ii) concerned the subject of a disagreement (as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable events (as described in paragraph (a)(1)(v) of said Item 304).

At a meeting held on April 23, 2024, the Audit Committee of each Fund's Board approved the selection of EY as the Fund's independent registered public accounting firm for the fiscal year ended October 31, 2024, in the case of Credit Suisse Commodity Return Strategy Fund, and the fiscal year ended December 31, 2024, in the case of Commodity Return Strategy Portfolio. EY has been each Fund's independent registered public accounting firm since June 19, 2024, and has informed each Fund that it has no material direct or indirect financial interest in the Fund. Representatives of EY will not be present at the Special Meeting, and, accordingly, will not have the opportunity to make a statement and will not be available to respond to questions.

The information in the table below is provided for services rendered to the Funds showing the amount of fees billed to each Fund during the Fund's last two fiscal years by PwC and EY, as applicable. For the engagement with PwC and EY, the Audit Committee of each Fund's Board approved in advance all audit services and non-audit services that PwC and EY provided to the Fund for its last two fiscal years indicated below.

The Audit Committee of the Board of each Fund is responsible for pre-approving (i) all audit and permissible non-audit services to be provided by the independent registered public accounting firm to the Fund and (ii) all permissible non-audit services to be provided by the independent registered public accounting firm to UBS AM (Americas) and any Covered Services Provider if the engagement relates directly to the operations and financial reporting of the Fund. The Audit Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to the Chairperson of the Audit Committee, and the Chairperson shall report to the Audit Committee, at its next regularly scheduled meeting after the Chairperson's pre-approval of such services, his or her decision(s). The Audit Committee may also establish detailed pre-approval policies and procedures for pre-approval of such services in accordance with applicable laws, including the delegation of some or all of the Audit Committee's pre-approval responsibilities to other persons (other than UBS AM (Americas) or the Fund's officers). Pre-approval by the Audit Committee of any permissible non-audit services shall not be required so long as: (i) the aggregate amount of all such permissible non-audit services provided to each Fund, UBS AM (Americas) and any Covered Services Provider constitutes not more than 5% of the total amount of revenues paid by the Fund to its independent registered public accounting firm during the fiscal year in which the permissible non-audit services are provided; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Audit Committee and approved by the Audit Committee (or its delegate(s)) prior to the completion of the audit.

ADDITIONAL INFORMATION

Proxy Voting and Shareholder Meeting

All properly executed and timely received proxy cards will be voted in accordance with the instructions marked thereon or otherwise provided therein. Accordingly, unless instructions to the contrary are marked, proxy cards will be voted for the approval of each of Proposal 1 and Proposal 2. A previously submitted proxy card can be revoked by mail (addressed to the Secretary of the applicable Fund, c/o UBS Asset Management (Americas) LLC, Eleven Madison Avenue, 9^th Floor, New York, New York 10010), voting again through the toll-free number or the Internet address listed in the proxy card, or at the Special Meeting by executing a superseding proxy card or by submitting a notice of revocation. Merely attending the Special Meeting, however, will not revoke any previously submitted proxy card.

All shareholders of record of each Fund on the Record Date are entitled to vote at the Special Meeting. Approval of Proposal 1 requires the vote of a "majority of the outstanding voting securities" of the respective Fund entitled to vote on the applicable Proposal voting separately. A "majority of the outstanding voting securities" is defined in the 1940 Act as either (i) the vote of 67% or more of the voting securities entitled to vote on the applicable Proposal that are present at the Special Meeting, if the holders of more than 50% of the outstanding shares are present or represented by proxy, or (ii) the vote of more than 50% of the outstanding voting securities entitled to vote on the applicable Proposal, whichever is less. Approval of Proposal 2 requires a plurality of the votes cast at the Special Meeting by the shareholders of the respective Fund voting separately.

A quorum for the Special Meeting will consist of the presence in person or by proxy of the holders of record of (i) in the case of Credit Suisse Commodity Return Strategy Fund, a series of Credit Suisse Commodity Strategy Funds, one-third of the shares of the Fund outstanding and entitled to vote at the Special Meeting, and (ii) in the case of Commodity Return Strategy Portfolio, a series of Credit Suisse Trust, a majority of the shares of the applicable Fund's outstanding and entitled to vote at the Special Meeting.

The Fund expects that broker-dealer firms holding shares of the Fund in "street name" for their customers will not be permitted applicable rules to vote on Proposal 1 on behalf of their customers and beneficial owners in the absence of voting instructions from their customers and beneficial owners, because Proposal 1 is a "non-routine" proposal. On the other hand, Proposal 2 is a "routine" proposal, and broker-dealer firms holding shares of the Fund in "street name" for their customers will be permitted to vote on Proposal 2 on behalf of their customers and beneficial owners in the absence of voting instructions from their customers and beneficial owners. Accordingly, the Fund may receive "broker non-votes." Broker non-votes occur when shares are held by brokers or nominees for which proxies have been returned but (a) voting instructions have not been received from the beneficial owners or persons entitled to vote, (b) the broker or nominee does not have discretionary voting power or elects not to exercise discretion on a particular matter, and (c) the shares are present at the Special Meeting. Broker non-votes will count as present for a quorum, but will have the effect of a negative vote against Proposal 1. Abstentions, if any, will have the effect of a negative vote against Proposal 1. We urge you to instruct your broker or other nominee to vote your shares.

In the event that the necessary quorum to transact business or the vote required to approve or reject the proposal described in the Joint Proxy Statement is not obtained at the Special Meeting with respect to a Fund, the persons named as proxies may propose one or more adjournments of the Special Meeting with respect to the Fund in accordance with applicable law to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of holders of the applicable Fund's shares present in person or by proxy at the Special Meeting. The persons named as proxies will vote in favor of such adjournment those proxies which they are entitled to vote in favor of the proposal described in the Joint Proxy Statement and will vote against any such adjournment those proxies to be voted against such proposal.

Shares of the Commodity Return Strategy Portfolio (the "Portfolio"), a series of Credit Suisse Trust, are sold to certain tax-qualified pension and retirement plans ("Qualified Plans") and insurance companies ("Insurance Companies") and their separate accounts and are used as investment options under the Qualified Plans and under variable annuity contracts and variable life insurance policies ("Variable Contracts") issued by the Insurance Companies. Variable Contract holders and Qualified Plan participants who select the Portfolio for investment through a Variable Contract or Qualified Plan have a beneficial interest in the Portfolio, but do not invest directly in or hold shares of the Portfolio. An Insurance Company or Qualified Plan that uses the Portfolio as a funding vehicle is, in most cases, the legal shareholder of the Portfolio and, as such, has sole voting power with respect to the shares. However, under current law, the Insurance Companies are required to solicit voting instructions from Variable Contract holders who beneficially own shares of the Portfolio as of the Record Date and must vote all shares held in the separate account in proportion to the voting instructions received for the Special Meeting. The Qualified Plans will also solicit voting instructions from Qualified Plan participants who beneficially own shares of the Portfolio as of the Record Date. The Insurance Companies and the Qualified Plans will vote shares of the Portfolio for which no instructions have been received in the same proportion as they vote shares for which they have received instructions, even in instances where a broker would be prevented from exercising discretion. As a result, the vote of a small number of shares could determine the outcome of the vote on the Proposal. Unmarked voting instructions will be voted in favor of the Proposal.

If any matter other than the Proposals properly comes before the Special Meeting, the shares represented by proxies will be voted on all such other proposals in the discretion of the person or persons voting the proxies. The Funds have not received notice of, and are not otherwise aware of, any other matter to be presented at the Special Meeting.

EQ Fund Solutions LLC (the "Agent") has been engaged by UBS AM (Americas) to assist with the distribution of proxy materials and the solicitation and tabulation of proxies at an aggregate cost of approximately $222,984 to $272,536, plus all reasonable out of pocket expenses incurred on behalf of each Fund. The solicitation cost will be borne by UBS AM (Americas) out of its own legitimate profits. As the Special Meeting date approaches, certain shareholders may receive a telephone call from a representative of the Agent if their vote has not yet been received. Authorization to permit the Agent to execute proxies may be obtained by telephonic or electronic transmitted instructions from shareholders. Proxies that are obtained telephonically will be recorded in accordance with the procedures set forth below.

Shareholders Sharing the Same Address

As permitted by law, only one copy of this Joint Proxy Statement may be delivered to shareholders residing at the same address, unless such shareholders have notified their respective Fund of their desire to receive multiple copies of the shareholder reports and proxy statements that the Fund sends. If you would like to receive an additional copy, please call (877) 283-0322 or write to Mutual Fund Operations c/o of David Shivkumar at Credit Suisse Funds, Eleven Madison Avenue, New York, New York 10010. The Funds will then promptly deliver, upon request, a separate copy of this Joint Proxy Statement to any shareholder residing at an address to which only one copy was mailed. Shareholders wishing to receive separate copies of their respective Fund's shareholder reports and proxy statements in the future, and shareholders sharing an address that wish to receive a single copy if they are receiving multiple copies, should also send a request as indicated.
