Credit Suisse Trust—Commodity Return Strategy Portfolio

Notes to consolidated financial statements

June 30, 2025 (unaudited)

**Note 1. Organization**

Credit Suisse Trust (the "Trust") is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"), which currently offers the Commodity Return Strategy Portfolio (the "Portfolio"). The Portfolio is a diversified, open-end management investment company that seeks total return that exceeds the return of its benchmark index, the Bloomberg Commodity Index Total Return (the "Index"). Shares of the Portfolio are not available directly to individual investors but may be offered only through (a) variable annuity contracts and variable life insurance policies offered by separate accounts of certain insurance companies and (b) tax qualified pension and retirement plans. The Portfolio may not be available in connection with a particular contract or plan. The Trust was organized under the laws of the Commonwealth of Massachusetts as a business trust on March 15, 1995.

UBS Asset Management (Americas) LLC ("UBS AM (Americas)" or the "Adviser"), the investment adviser to the Portfolio, is registered as an investment adviser with the Securities and Exchange Commission (the "SEC") and as a Commodity Pool Operator with the Commodity Futures Trading Commission. UBS Asset Management (US) Inc. ("UBS AM (US)") serves as the principal underwriter for the Portfolio. UBS AM (Americas) and UBS AM (US) are indirect wholly owned subsidiaries of UBS Group AG. UBS Group AG is an internationally diversified organization with headquarters in Zurich, Switzerland. UBS Group AG operates in many areas of the financial services industry. The Portfolio intends to gain exposure to commodity derivatives through investing in a wholly-owned subsidiary, Credit Suisse Cayman Commodity Fund II, Ltd. (the "Subsidiary"), organized under the laws of the Cayman Islands. The Subsidiary invests in commodity-linked derivative instruments, such as swaps and futures. The Subsidiary may also invest in debt securities, some of which are intended to serve as margin or collateral for the Subsidiary's derivatives positions.

The Subsidiary is managed by the same portfolio managers that manage the Portfolio and the accompanying financial statements reflect the financial position of the Portfolio and the Subsidiary and the results of operations on a consolidated basis. The consolidated financial statements include portfolio holdings of the Portfolio and the Subsidiary and all intercompany transactions and balances have been eliminated. The Portfolio may invest up to 25% of its total assets in the Subsidiary. As of June 30, 2025, the Portfolio held $93,885,976 in the Subsidiary, representing 14.9% of the Portfolio's consolidated net assets. For the six months ended June 30, 2025, the net realized gain on securities and other financial instruments held in the Subsidiary was $32,055,626.

Subsequent references to the Portfolio within the Notes to Consolidated Financial Statements collectively refer to the Portfolio and the Subsidiary, unless the context otherwise requires.

The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares. Each class of shares represents an equal pro rata interest in the Portfolio, except the share classes bear different expenses.

In this reporting period, the Portfolio adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update 2023-07, Segment Reporting ("Topic 280")—Improvements to Reportable Segment Disclosures ("ASU 2023-07"). Adoption of the new standard impacted financial statement disclosures only and did not affect the Portfolio's financial position or the results of its operations. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity's chief operating decision maker ("CODM") to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The Portfolio's portfolio management team acts as the Portfolio's CODM. The Portfolio represents a single operating segment, as the CODM monitors the operating results of the Portfolio as a whole and the Portfolio's long-term strategic asset allocation is predetermined in accordance with the Portfolio's single investment objective which is executed by the Portfolio's portfolio managers as a team. The financial information in the form of the Portfolio's portfolio composition, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions) which are used by the CODM

to assess the Portfolio's comparative benchmarks and to make resource allocation decisions for the Portfolio's single segment, is consistent with that presented within the Portfolio's financial statements. Segment assets are reflected on the accompanying statement of assets and liabilities as "total assets" and significant segment expenses are listed on the accompanying statement of operations.

**Note 2. Significant accounting policies**

The following is a summary of significant accounting policies followed by the Portfolio in the preparation of its consolidated financial statements. The policies are in accordance with generally accepted accounting principles in the United States of America ("GAAP"). The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements. Actual results could differ from those estimates. The Portfolio is considered an investment company for financial reporting purposes under GAAP and follows the accounting and reporting guidance in FASB Accounting Standards Codification ("ASC") Topic 946—Financial Services—Investment Companies.

A) SECURITY VALUATION—The Board of Trustees (the "Board") is responsible for the Portfolio's valuation process. The Board has delegated the supervision of the daily valuation process to the Adviser, who has established a Pricing Committee and a Pricing Group, which, pursuant to the policies adopted by the Board, are responsible for making fair valuation determinations and overseeing the Portfolio's pricing policies. The net asset value ("NAV") of the Portfolio is determined daily as of the close of regular trading on the New York Stock Exchange, Inc. (the "Exchange") on each day the Exchange is open for business. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. These pricing services generally price fixed income securities assuming orderly transactions of an institutional "round lot" size, but some trades occur in smaller "odd lot" sizes which may be effected at lower prices than institutional round lot trades. Structured note agreements are valued in accordance with a dealer-supplied valuation based on changes in the value of the underlying index. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. Forward contracts are valued at the London closing spot rates and the London closing forward point rates on a daily basis. The currency forward contract pricing model derives the differential in point rates to the expiration date of the forward and calculates its present value. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. Investments in open-ended mutual funds are valued at the NAV as reported on each business day and under normal circumstances. Securities for which market quotations are not readily available are valued at their fair value as determined in good faith by the Adviser, as the Board's valuation designee (as defined in Rule 2a-5 under the 1940 Act), in accordance with the Adviser's procedures. The Board oversees the Adviser in its role as valuation designee in accordance with the requirements of Rule 2a-5 under the 1940 Act. The Portfolio may utilize a service provided by an independent third party to fair value certain securities. When fair value pricing is employed, the prices of securities used by the Portfolio to calculate its NAV may differ from quoted or published prices for the same securities. If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the Adviser to be unreliable, the market price may be determined by the Adviser using quotations from one or more brokers/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Portfolio calculates its NAV, these securities will be fair valued in good faith by the Pricing Group, in accordance with procedures established by the Adviser.

Notes to consolidated financial statements

June 30, 2025 (unaudited)

The Portfolio uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

GAAP established a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at each measurement date. These inputs are summarized in the three broad levels listed below:

Level 1—quoted prices in active markets for identical investments

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

Level 3—significant unobservable inputs (including the Portfolio's own assumptions in determining the fair value of investments)

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of June 30, 2025 in valuing the Portfolio's assets and liabilities carried at fair value:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Assets** | **Level 1** | **Level 2** | **Level 3** | **Total** |

\* Other financial instruments include unrealized appreciation (depreciation) on futures and swap contracts.

For the six months ended June 30, 2025, there were no transfers in or out of Level 3. All transfers, if any, are assumed to occur at the end of the reporting period.

B) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES—The Portfolio has adopted a derivatives risk management program pursuant to Rule 18f-4 under the 1940 Act in order to assess and manage the Portfolio's derivatives risk, taking into account the Portfolio's derivatives transactions and how these transactions interact with the Portfolio's other investments. Because the Portfolio engages in derivatives transactions beyond a certain amount in order to pursue its investment objectives and policies, the Portfolio is required to comply with value at risk ("VaR") based limits on its leverage risk. The Portfolio adopted amendments to authoritative guidance on disclosures about derivative instruments and hedging activities which require that a portfolio disclose (a) how and why an entity uses derivative instruments, (b) how derivative instruments and hedging activities are accounted for and (c) how derivative

instruments and related hedging activities affect a portfolio's financial position, financial performance and cash flows.

The following table presents the fair value and the location of derivatives within the Consolidated Statement of Assets and Liabilities at June 30, 2025 and the effect of these derivatives on the Consolidated Statement of Operations for the six months ended June 30, 2025.

<sup>1</sup> Generally, the balance sheet location for asset derivatives is receivables/unrealized appreciation (depreciation) and for liability derivatives is payables/unrealized appreciation (depreciation).

<sup>2</sup> Includes cumulative appreciation (depreciation) of futures contracts as reported in the Consolidated Schedule of Investments. Only variation margin is reported within the receivables and/or payables on the Consolidated Statement of Assets and Liabilities.

The notional amount of futures contracts and swap contracts open at June 30, 2025 is reflected in the Consolidated Schedule of Investments. For the six months ended June 30, 2025, the Portfolio held average monthly notional values of $246,569,989 and $22,271,227 in long futures contracts and short futures contracts, respectively, and $263,890,787 in swap contracts.

The Portfolio is a party to International Swap and Derivatives Association, Inc. ("ISDA") Master Agreements ("Master Agreements") with certain counterparties that govern over-the-counter derivative (including total return, credit default and interest rate swaps) and foreign exchange contracts entered into by the Portfolio. The Master Agreements may contain provisions regarding, among other things, the parties' general obligations, representations, agreements, collateral requirements, events of default and early termination. Termination events applicable to the Portfolio may occur upon a decline in the Portfolio's net assets below a specified threshold over a certain period of time.

The following table presents by counterparty the Portfolio's derivative liabilities, net of related collateral pledged by the Portfolio, at June 30, 2025 :

Notes to consolidated financial statements

June 30, 2025 (unaudited)

C) SECURITY TRANSACTIONS AND INVESTMENT INCOME/EXPENSE—Security transactions are accounted for on a trade date basis. Interest income/expense is recorded on the accrual basis. The Portfolio amortizes premiums and accretes discounts using the effective interest method. Dividend income/expense is recorded on the ex-dividend date. Certain expenses are class-specific expenses, vary by class and are charged only to that class. Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative NAV of the outstanding shares of that class. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Portfolio may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS—Dividends from net investment income, if any, are declared and paid quarterly. Distributions of net realized capital gains, if any, are declared and paid at least annually. However, to the extent that a net realized capital gain can be reduced by a capital loss carryforward, such gain will not be distributed. Dividends and distributions to shareholders of the Portfolio are recorded on the ex-dividend date and are determined in accordance with federal income tax regulations, which may differ from GAAP.

E) FEDERAL AND OTHER TAXES—No provision is made for federal taxes as it is the Portfolio's intention to continue to qualify as a regulated investment company ("RIC") under the Internal Revenue Code of 1986, as amended (the "Code"), and to make the requisite distributions to its shareholders, which will be sufficient to relieve it from federal income and excise taxes.

In order to qualify as a RIC under the Code, the Portfolio must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. One of these requirements is that the Portfolio derive at least 90% of its gross income for each taxable year from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, other income derived with respect to its business of investing in such stock, securities or currencies or net income derived from interests in certain publicly-traded partnerships ("Qualifying Income"). The Internal Revenue Service ("IRS") has issued a ruling that income realized from certain types of commodity-linked derivatives would not be Qualifying Income. As a result, the Portfolio's ability to realize income from investments in such commodity-linked derivatives as part of its investment strategy would be limited to a maximum of 10% of its gross income. The Portfolio may invest in structured notes designed to track the performance of the Index. The Portfolio may, through its investment in the Subsidiary, invest in commodity-linked swaps and/or futures contracts.

If the Portfolio is unable to ensure continued qualification as a RIC, the Portfolio may be required to change its investment objective, policies or techniques, or may be liquidated. If the Portfolio fails to qualify as a RIC, the Portfolio will be subject to federal income tax on its net income and capital gains at regular corporate rates (without reduction for distributions to shareholders). If the Portfolio were to fail to qualify as a RIC and become subject to federal income tax, shareholders of the Portfolio would be subject to the risk of diminished returns.

The Portfolio adopted the authoritative guidance for uncertainty in income taxes and recognizes a tax benefit or liability from an uncertain position only if it is more likely than not that the position is sustainable based solely on its technical merits and consideration of the relevant taxing authority's widely understood administrative practices and procedures. The Portfolio has reviewed its current tax positions and has determined that no provision for income tax is required in the Portfolio's financial statements. The Portfolio's federal and state income and federal excise tax returns for each of the tax years in the four year period ended June 30, 2025, for which the applicable statutes of limitations have not expired are subject to examination by the IRS and state departments of revenue.

F) CASH—The Portfolio's uninvested cash balance is held in an interest bearing variable rate demand deposit account at State Street Bank and Trust Company ("SSB"), the Portfolio's custodian.

------

Credit Suisse Trust—Commodity Return Strategy Portfolio

Notes to consolidated financial statements

June 30, 2025 (unaudited)

G) FUTURES—The Portfolio may enter into futures contracts to the extent permitted by its investment policies and objectives. The Portfolio may use futures contracts to gain exposure to or hedge against changes in commodities. Upon entering into a futures contract, the Portfolio is required to deposit cash and/or pledge U.S. Government securities as initial margin with a Futures Commission Merchant ("FCM"). Subsequent payments, which are dependent on the daily fluctuations in the value of the underlying instrument, are made or received by the Portfolio each day (daily variation margin) and are recorded as unrealized gains or losses in the Consolidated Statement of Operations until the contracts are closed. When the contracts are closed, the Portfolio records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Portfolio's basis in the contract. Risks of entering into futures contracts for hedging purposes include the possibility that a change in the value of the contract may not correlate with the changes in the value of the underlying instruments. Futures have minimal counterparty credit risk because futures are exchange traded and the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. In addition, the purchase of a futures contract involves the risk that the Portfolio could lose more than the original margin deposit and subsequent payments may be required for a futures transaction. The Portfolio's open futures contracts are disclosed in the Consolidated Schedule of Investments. At June 30, 2025, the amount of restricted cash held at brokers related to open futures contracts was $647,064.

The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM's proprietary activities. A customer's cash and other equity deposited with an FCM are considered commingled with all other customer funds subject to the FCM's segregation requirements. In the event of an FCM's insolvency, recovery may be limited to the Portfolio's pro-rata share of segregated customer funds available. It is possible that the recovery amount could be less than the total of cash and other equity deposited.

H) SWAPS—The Portfolio may enter into commodity index swaps either for hedging purposes or to seek to increase total return. A swap contract is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset or notional principal amount. The Portfolio will enter into swap contracts only on a net basis, which means that the two payment streams are netted out, with the Portfolio receiving or paying, as the case may be, only the net amount of the two payments. Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The extent of the Portfolio's exposure to credit and counterparty risks is the discounted net value of the cash flows to be received from the counterparty over the contract's remaining life, to the extent that the amount is positive. These risks are mitigated by having a master netting arrangement between the Portfolio and the counterparty and by the posting of collateral by the counterparty to the Portfolio to cover the Portfolio's exposure to the counterparty. Therefore, the Portfolio considers the creditworthiness of each counterparty as well as the amounts posted by the counterparty pursuant to the master netting agreement to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying reference asset or index.

The Portfolio may enter into total return swap contracts, involving commitments to pay interest in exchange for a market-linked return, both based on notional amounts. The Portfolio may invest in total return swap contracts for hedging purposes or to seek to increase total return. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the Portfolio will receive a payment from or make a payment to the counterparty.

The Portfolio records unrealized gains or losses on a daily basis representing the value and the current net receivable or payable relating to open swap contracts. Net amounts received or paid on the swap contract are recorded as realized gains or losses. Fluctuations in the value of swap contracts are recorded for financial statement purposes as unrealized appreciation or depreciation from swap contracts. Realized gains and losses from terminated swaps are included in net realized gains/losses from swap contracts. The Portfolio's open swap contracts are disclosed in the

June 30, 2025 (unaudited)

Consolidated Schedule of Investments. At June 30, 2025, the amount of restricted cash held at brokers related to open swap contracts was $4,216,351.

I) COMMODITY INDEXED STRUCTURED NOTES—The Portfolio may invest in structured notes whose value is based on the price movements of the Index. The structured notes are often leveraged, increasing the volatility of each note's value relative to the change in the underlying linked financial instrument. The value of these notes will rise and fall in response to changes in the Index. Structured notes may entail a greater degree of market risk than other types of debt securities because the investor bears the risk of the underlying commodity index. Structured notes may also be more volatile, less liquid, and more difficult to accurately price than less complex securities or more traditional debt securities. Fluctuations in the value of the structured notes are recorded as unrealized gains and losses in the accompanying financial statements. Payments are recorded as interest income. These notes are subject to prepayment, credit and interest rate risks. The Portfolio has the option to request prepayment from the issuer. At maturity, or when a note is sold, the Portfolio records a realized gain or loss. At June 30, 2025, the value of these securities comprised 7.2% of the Portfolio's net assets and resulted in unrealized depreciation of $3,623,518.

J) SECURITIES LENDING—The initial collateral received by the Portfolio is required to have a value of at least 102% of the market value of domestic securities on loan (including any accrued interest thereon) and 105% of the market value of foreign securities on loan (including any accrued interest thereon). The collateral is maintained thereafter at a value equal to at least 102% of the current market value of the securities on loan. The market value of loaned securities is determined at the close of each business day of the Portfolio and any additional required collateral is delivered to the Portfolio, or excess collateral returned by the Portfolio, on the next business day. Cash collateral received by the Portfolio in connection with securities lending activity may be pooled together with cash collateral for other funds/portfolios advised by UBS AM (Americas) and may be invested in a variety of investments, including funds advised by SSB or an affiliate, the Portfolio's securities lending agent, or money market instruments. However, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. The remaining maturities of the securities lending transactions are considered overnight and continuous. Loans are subject to termination by the Portfolio or the borrower at any time.

SSB has been engaged by the Portfolio to act as the Portfolio's securities lending agent. As of June 30, 2025, the Portfolio had outstanding loans of securities to certain approved brokers for which the Portfolio received collateral:

---

The Portfolio's securities lending arrangement provides that the Portfolio and SSB will share the net income earned from securities lending activities. Securities lending income is accrued as earned. For the six months ended June 30, 2025, total earnings received in connection with securities lending arrangements was $165,606, of which

$154,185 was rebated to borrowers (brokers). The Portfolio retained $8,566 in income, and SSB, as lending agent, was paid $2,855.

K) OTHER—In the normal course of business, the Portfolio trades financial instruments and enters into financial transactions for which risk of potential loss exists due to changes in the market (market risk) or failure of the other party to a transaction to perform (credit risk). Similar to credit risk, the Portfolio may be exposed to counterparty risk, including with respect to securities lending, or the risk that an institution or other entity with which the Portfolio has unsettled or open transactions will default. The potential loss could exceed the value of the financial assets recorded in the consolidated financial statements. Financial assets, which potentially expose the Portfolio to credit risk, consist principally of cash due from counterparties and investments. The extent of the Portfolio's exposure to credit and counterparty risks in respect to these financial assets approximates their carrying value as recorded in the Portfolio's Consolidated Statement of Assets and Liabilities.

**Note 3. Transactions with affiliates and related parties**

UBS AM (Americas) serves as the Portfolio's investment adviser and co-administrator.

This contract may not be terminated before May 1, 2026. For the six months ended June 30, 2025, the fees waived/reimbursed by UBS AM (Americas) was $30,104.

On August 18, 2021, reverse share splits were announced for each class of the Portfolio, pursuant to which shareholders received one share in exchange for every six shares of the Portfolio.

The reverse share splits were effective October 15, 2021. The reverse splits reduced the number of outstanding shares of each class of the Portfolio and proportionately increased the NAV per share of each class of the Portfolio such that the market value of the Portfolio's shares remained the same. The reverse share splits applied the same ratio to each class of shares of the Portfolio. A reverse share split does not alter the rights or total value of a shareholder's investment in the Portfolio, nor will it be a taxable event for Portfolio investors.

The Capital Share Transactions and Financial Highlights prior to October 15, 2021 for the Portfolio has been adjusted to reflect the reverse share split.

June 30, 2025 (unaudited)

On June 30, 2025, the number of shareholders that held 5% or more of the outstanding shares of the Portfolio was as follows:

---

| | | |
|:---|:---|:---|
| | **Number of<br>shareholders** | **Approximate percentage<br>of outstanding shares** |
| Class 1 | 3 | 86% |
| Class 2 | 4 | 100% |

---

The Portfolio's performance may be negatively impacted in the event one or more of the Portfolio's greater than 5% shareholders were to redeem at a given time. Some of the shareholders may be omnibus accounts, which hold shares on behalf of individual shareholders.

**Note 7. Contingencies**

In the normal course of business, the Portfolio may provide general indemnifications pursuant to certain contracts and organizational documents. The Portfolio's maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated; however, based on experience, the risk of loss from such claims is considered remote.

**Note 8. Subsequent Events**

In preparing the consolidated financial statements as of June 30, 2025, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements through the date of release of this report.

On May 28, 2025, UBS AM (Americas), the Portfolio's investment adviser, issued a press release announcing an agreement with an affiliate (the "Affiliate") of Cantor Fitzgerald Investment Advisors, L.P. ("Cantor Fitzgerald"), to sell UBS AM (Americas)'s O'Connor investment platform to the Affiliate (the "Transaction"). The Transaction remains subject to various approvals and regulatory requirements. Subject to satisfaction of these requirements, UBS AM (Americas) expects that the O'Connor investment management and support teams, which includes the Portfolio's portfolio management team, will transition to the Affiliate. The Affiliate has no operating history and is a newly-formed investment adviser that recently registered with the U.S. Securities and Exchange Commission (the "SEC") as an investment adviser under the Investment Advisers Act of 1940, as amended. The Affiliate is an indirect wholly-owned subsidiary of Cantor Fitzgerald, and is under common control with Cantor Fitzgerald, which has been registered with the SEC as an investment adviser since 2011. The parties to the Transaction expect the initial closing of the Transaction to occur by the end of the fourth quarter of 2025, but it remains subject to regulatory and investor approvals and other customary closing conditions.

In connection with the Transaction referred to above, the parties to the Transaction expect that all investment management responsibilities for the Portfolio will be transferred from UBS AM (Americas) to Cantor Fitzgerald. Any such transfer of investment management responsibilities will be subject to, among other approvals, approval by the Portfolio's Board of Trustees and its respective shareholders. Additional details regarding any such transfer of investment management responsibilities of the Portfolio from UBS AM (Americas) to Cantor Fitzgerald, including timing, will be forthcoming.
