Report of Independent Registered Public Accounting Firm

To the General Partner of CMF Winton Master L.P.,

Opinion on the Financial Statements

We have audited the accompanying statements of financial condition of CMF Winton Master L.P. (the “Partnership”), including the condensed schedules of investments, as of December 31, 2020 and 2019, the related statements of income and expenses, and changes in partners’ capital for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Partnership at December 31, 2020 and 2019, and the results of its operations and changes in its partners’ capital for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Partnership is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2020 and 2019, by correspondence with the custodian and brokers. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to those charged with governance and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. We determined that there are no critical audit matters.

CMF Winton Master L.P.

Notes to Financial Statements

CMF Winton Master L.P. (the “Master”) is a limited partnership organized under the partnership laws of the State of New York to engage in the speculative trading of a diversified portfolio of commodity interests including futures, option, swap and forward contracts. The sectors traded include currencies, energy, grains, indices, U.S. and non-U.S. interest rates, livestock, metals and softs. The commodity interests that are traded by the Master are volatile and involve a high degree of market risk. The General Partner (defined below) may also determine to invest up to all of the Master’s assets in United States (“U.S.”) Treasury bills and/or money market mutual funds, including money market mutual funds managed by Morgan Stanley or its affiliates. The Master may sell an unlimited number of redeemable units of limited partnership interest (“Redeemable Units”). The Redeemable Units of the Master are used solely for accounting purposes and do not represent units issued legally.

Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the “General Partner”) and commodity pool operator of the Master. The General Partner is a wholly-owned subsidiary of Morgan Stanley Domestic Holdings, Inc. (“MSD Holdings”). MSD Holdings is ultimately owned by Morgan Stanley. Morgan Stanley is a publicly held company whose shares are listed on the New York Stock Exchange. Morgan Stanley is engaged in various financial services and other businesses. All trading decisions for the Master are made by the Advisor (defined below).

On November 1, 2004 (commencement of trading operations), Ceres Orion L.P. (formerly, Orion Futures Fund L.P.) (“Orion”) allocated a portion of its capital to the Master. On February 1, 2007, Ceres Abingdon L.P. (formerly, Managed Futures Premier Abingdon L.P.) (“Abingdon”) allocated a portion of its capital to the Master. On March 1, 2007, Global Futures Fund Ltd. (“Global Futures”) allocated a portion of its capital to the Master. Effective July 31, 2019, Global Futures terminated operations and redeemed its investment in the Master. Effective September 30, 2020, Orion redeemed its investment in the Master. Effective December 31, 2020, Abingdon terminated operations and redeemed its investment in the Master. References herein to a “Fund” or the “Funds” may include as relevant, reference to Global Futures, Abingdon and Orion. The Master permits commodity pools controlled by the General Partner and managed by Winton Capital Management Limited (the “Advisor”) pursuant to Diversified Macro Strategies (formerly, the Winton Futures Program), the Advisor’s proprietary, systematic trading program, to invest together in one trading vehicle.

During the periods covered by this report, the Master’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. JPMorgan Chase Bank, N.A. (“JPMorgan”) also was a foreign exchange forward contract counterparty for the Master. The Master deposited a portion of its cash in a non-trading bank account at JPMorgan.

Prior to the close of business on December 31, 2020, the Master operated under a structure where its investor(s) consisted of the Fund(s). There were no investors in the Master as of the close of business on December 31, 2020. Please refer to Note 9 “Subsequent Events” describing an investor in the Master subsequent to December 31, 2020.

CMF Winton Master L.P.

Notes to Financial Statements

The Master will be liquidated upon the first to occur of the following: December 31, 2024; or under certain other circumstances as set forth in the limited partnership agreement of the Master, as may be amended from time to time (the “Limited Partnership Agreement”).

The General Partner has delegated certain administrative functions to SS&C Technologies, Inc., a Delaware corporation, currently doing business as SS&C GlobeOp (the “Administrator”). Pursuant to a master services agreement, the Administrator furnishes certain administrative, accounting, regulatory reporting, tax and other services as agreed from time to time. In addition, the Administrator maintains certain books and records of the Master.

Master’s Cash. The Master’s restricted and unrestricted cash includes cash denominated in foreign currencies of $739,641 (cost of $703,743) and $5,683,449 (cost of $5,580,696) at December 31, 2020 and 2019, respectively.

CMF Winton Master L.P.

Notes to Financial Statements

The General Partner administers the business and affairs of the Master, including selecting one or more advisors to make trading decisions for the Master.

The General Partner, on behalf of the Master, has entered into a management agreement (the “Management Agreement”) with the Advisor, a registered commodity trading advisor. The Advisor is not affiliated with the General Partner or MS&Co. and is not responsible for the organization or operation of the Master. The Management Agreement provides that the Advisor has sole discretion in determining the investment of the assets of the Master. All management fees in connection with the Management Agreement are borne by the Funds. The Management Agreement may be terminated upon notice by either party.

The Master has entered into a customer agreement with MS&Co. (the “Customer Agreement”) and a foreign exchange brokerage account agreement with MS&Co.

CMF Winton Master L.P.

Notes to Financial Statements

Under the Customer Agreement and the foreign exchange brokerage account agreement, the Master pays MS&Co. trading fees for the clearing and, where applicable, the execution of transactions. Further, all trading, exchange, clearing, user, give-up, floor brokerage and National Futures Association fees (collectively, the “clearing fees”) are borne by the Master and allocated to the Funds. All other fees are borne by the Funds. The Master’s cash deposited with MS&Co. is held in segregated bank accounts to the extent required by Commodity Futures Trading Commission regulations. The Master’s restricted cash is equal to the cash portion of assets on deposit to meet margin requirements, as determined by the exchange or counterparty, and required by MS&Co. and/or JPMorgan, as applicable. At December 31, 2020 and 2019, the amount of restricted and unrestricted cash held by the Master for margin requirements was $7,784,471 and $32,343,512, respectively. Cash that is not classified as restricted cash is therefore classified as unrestricted cash. The Customer Agreement may generally be terminated upon notice by either party.

On July 12, 2017, the Master entered into certain agreements with JPMorgan in connection with trading in forward foreign currency contracts. These agreements include a foreign exchange and bullion authorization agreement (“FX Agreement”), an International Swap Dealers Association, Inc. master agreement (“Master Agreement”), a schedule to the Master Agreement, a 2016 credit support annex for variation margin to the schedule and an institutional account agreement. Under the FX Agreement, JPMorgan charges a fee on the aggregate foreign currency transactions entered into on behalf of the Master during a month.

The Master was formed for the purpose of trading contracts in a variety of commodity interests, including derivative financial instruments and derivative commodity interests. The results of the Master’s trading activities are shown in the Statements of Income and Expenses.

The Customer Agreement and/or foreign exchange brokerage account agreement gives the Master the legal right to net unrealized gains and losses on open futures and open forward contracts. The Master nets, for financial reporting purposes, the unrealized gains and losses on open futures and open forward contracts in the Statements of Financial Condition as the criteria under ASC 210-20, “Balance Sheet,” have been met.

All of the commodity interests owned by the Master are held for trading purposes. The monthly average number of futures contracts traded during the years ended December 31, 2020 and 2019 was 5,992 and 16,954, respectively. The monthly average number of metals forward contracts traded during the years ended December 31, 2020 and 2019 was 934 and 1,569, respectively. The monthly average notional values of currency forward contracts traded during the years ended December 31, 2020 and 2019 was $79,681,411 and $208,734,838, respectively.

The following table indicates the trading gains and losses, by market sector, on derivative instruments for the years ended December 31, 2020, 2019 and 2018.

Master’s Fair Value Measurements. Fair value is defined as the value that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety.

The fair value of exchange-traded futures, option and forward contracts is determined by the various exchanges, and reflects the settlement price for each contract as of the close of business on the last business day of the reporting period. The fair value of foreign currency forward contracts is extrapolated on a forward basis from the spot prices quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period from various exchanges. The fair value of non-exchange-traded foreign currency option contracts is calculated by applying an industry standard model application for options valuation of foreign currency options, using as input the spot prices, interest rates, and option implied volatilities quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period. U.S. Treasury bills are valued at the last available bid price received from independent pricing services as of the close of the last business day of the reporting period.

The Master considers prices for commodity futures, exchange-traded swap and option contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of U.S. Treasury bills, non-exchange-traded forward, swap and certain option contracts for which market quotations are not readily available are priced by pricing services that derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the years ended December 31, 2020 and 2019, the Master did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of the General Partner’s assumptions and internal valuation pricing models (Level 3).

Notes to Financial Statements

Subscriptions are accepted monthly from investors who become limited partners on the first day of the month after their subscriptions are processed. Distributions are made on a pro-rata basis at the sole discretion of the General Partner. No distributions have been made to date. The General Partner does not intend to make any distributions of the Master’s profits, except for distribution of interest income to feeder funds, as applicable. A limited partner may withdraw all or part of its capital contribution and undistributed profits, if any, from the Master as of the end of any month (the “Redemption Date”) after a request for redemption has been made to the General Partner at least three days in advance of the Redemption Date. Such withdrawals are classified as a liability when the limited partner elects to redeem and informs the Master.

CMF Winton Master L.P.

Notes to Financial Statements

In the normal course of business, the Master is party to financial instruments with off-balance sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include forwards, futures, options and swaps, whose values are based upon an underlying asset, index, or reference rate, and generally represent future commitments to exchange currencies or cash balances, or to purchase or sell other financial instruments at specific terms at specified future dates, or, in the case of derivative commodity instruments, to have a reasonable possibility to be settled in cash, through physical delivery or with another financial instrument. These instruments may be traded on an exchange, a swap execution facility or over-the-counter (“OTC”). Exchange-traded instruments include futures and certain standardized forward, option and swap contracts. Certain swap contracts may also be traded on a swap execution facility or OTC. OTC contracts are negotiated between contracting parties and also include certain forward and option contracts. Each of these instruments is subject to various risks similar to those related to the underlying financial instruments, including market and credit risk. In general, the risks associated with OTC contracts are greater than those associated with exchange-traded instruments because of the greater risk of default by the counterparty to an OTC contract. The General Partner estimates that at any given time approximately 2.9% to 34.5% of the Master’s contracts are traded OTC.

Futures Contracts. The Master trades futures contracts. A futures contract is a firm commitment to buy or sell a specified quantity of investments, currency or a standardized amount of a deliverable grade commodity, at a specified price on a specified future date, unless the contract is closed before the delivery date or the delivery quantity is something where physical delivery cannot occur (such as the S&P 500 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Master each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. When the contract is closed, the Master records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in futures contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the futures broker, with the exchange on which the contracts are traded. Net realized gains (losses) and net change in unrealized gains (losses) on futures contracts are included in the Statements of Income and Expenses.

Forward Foreign Currency Contracts. Forward foreign currency contracts are those contracts where the Master agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed-upon future date. Forward foreign currency contracts are valued daily, and the Master’s net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in the Statements of Financial Condition. Net realized gains (losses) and net change in unrealized gains (losses) on foreign currency contracts are recognized in the period in which the contract is closed or the changes occur, respectively, and are included in the Statements of Income and Expenses.

London Metal Exchange Forward Contracts. Metal contracts traded on the London Metal Exchange (“LME”) represent a firm commitment to buy or sell a specified quantity of aluminum, copper, lead, nickel, tin, zinc or other metal. LME contracts traded by the Master are cash settled based on prompt dates published by the LME. Variation margin may be made or received by the Master each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. A contract is considered offset when all long positions have been matched with a like number of short positions settling on the same prompt date. When the contract is closed at the prompt date, the Master records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in LME contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the broker, with the LME. Net realized gains (losses) and net change in unrealized gains (losses) on metal contracts are included in the Statements of Income and Expenses.

CMF Winton Master L.P.

Notes to Financial Statements

Market risk is the potential for changes in the value of the financial instruments traded by the Master due to market changes, including interest and foreign exchange rate movements and fluctuations in commodity or security prices. Market risk is directly impacted by the volatility and liquidity in the markets in which the related underlying assets are traded. The Master is exposed to market risk equal to the value of futures and forward contracts held and unlimited liability on such contracts sold short.

Credit risk is the possibility that a loss may occur due to the failure of a counterparty to perform according to the terms of a contract. The Master’s risk of loss in the event of a counterparty default is typically limited to the amounts recognized in the Statements of Financial Condition and is not represented by the contract or notional amounts of the instruments. The Master’s risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Master to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Master has credit risk and concentration risk, as MS&Co., MS&Co. affiliate and/or JPMorgan are counterparties or brokers with respect to the Master’s assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through MS&Co. or an MS&Co. affiliate, the Master’s counterparty is an exchange or clearing organization.

The General Partner monitors and attempts to mitigate the Master’s risk exposure on a daily basis through financial, credit and risk management monitoring systems and, accordingly, believes that it has effective procedures for evaluating and limiting the credit and market risks to which the Master may be subject. These monitoring systems generally allow the General Partner to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures, forward and option contracts by sector, margin requirements, gain and loss transactions and collateral positions.

The majority of these instruments mature within one year of the inception date. However, due to the nature of the Master’s business, these instruments may not be held to maturity.

In the ordinary course of business, the Master enters into contracts and agreements that contain various representations and warranties and which provide general indemnifications. The Master’s maximum exposure under these arrangements cannot be determined, as this could include future claims that have not yet been made against the Master. The General Partner considers the risk of any future obligation relating to these indemnifications to be remote.

Since its discovery in December 2019, a new strain of coronavirus, which causes the viral disease known as COVID-19, has spread from China to many other countries, including the United States. The outbreak has been declared a pandemic by the World Health Organization, and the U.S. Health and Human Services Secretary has declared a public health emergency in the United States in response to the outbreak.

The outbreak of the novel coronavirus in many countries is having and will likely continue to have an adverse impact on global commercial activity, which has contributed to significant volatility in financial markets. The global impact of the outbreak has been rapidly evolving, and as cases of the virus have been identified in additional countries, many countries have reacted by instituting quarantines and restrictions on travel. These actions are creating disruption in supply chains, and adversely impacting a number of industries, including but not limited to transportation, hospitality, and entertainment.

The impact of COVID-19 on the U.S. and world economies, and the extent of and effectiveness of any responses taken on a national and local level, is uncertain and could result in a world-wide economic downturn and disrupt financial markets that impact trading programs in unanticipated and unintended ways.

The rapid development of this situation precludes any prediction as to the ultimate adverse impact of the novel coronavirus. Nevertheless, the novel coronavirus presents material uncertainty and risk with respect to the Master’s investments and operations.
