To the Limited Partners of

Cambridge Master Fund L.P.

To the best of the knowledge and belief of the undersigned, the information contained herein is accurate and complete.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners of

Cambridge Master Fund L.P.:

We have audited the accompanying statements of financial condition of Cambridge Master Fund L.P. (the “Partnership”), including the condensed schedules of investments, as of December 31, 2014 and 2013, and the related statements of income and expenses and changes in partners’ capital for each of the two years in the period ended December 31, 2014 and the period September 1, 2012 (commencement of trading operations) to December 31, 2012. These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Partnership is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of Cambridge Master Fund L.P. as of December 31, 2014 and 2013, and the results of its operations and changes in its partners’ capital for each of the two years in the period ended December 31, 2014 and for the period September 1, 2012 (commencement of trading operations) to December 31, 2012, in conformity with accounting principles generally accepted in the United States of America.

Cambridge Master Fund L.P. (the “Master”) is a limited partnership organized under the partnership laws of the State of Delaware on July 30, 2012, to engage in the speculative trading of a portfolio of commodity interests, including futures contracts, options, swaps and forward contracts. Cambridge Master exclusively trades in the currency sector. The commodity interests that are traded by the Master are volatile and involve a high degree of market risk.

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 wholly owned by Morgan Stanley Smith Barney Holdings LLC (“MSSB Holdings”). MSSB 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. Prior to June 28, 2013, Morgan Stanley indirectly owned a majority equity interest in MSSB Holdings and Citigroup Inc. indirectly owned a minority equity interest in MSSB Holdings. Prior to July 31, 2009, the date as of which MSSB Holdings became its owner, the General Partner was wholly owned by Citigroup Financial Products Inc., a wholly owned subsidiary of Citigroup Global Markets Holdings Inc., the sole owner of which is Citigroup Inc. As of December 31, 2014, all trading decisions for the Master are made by the Advisor (defined below).

On September 1, 2012 (commencement of trading operations), Emerging CTA Portfolio L.P. (“Emerging CTA”), allocated a portion of its capital to the Master. On November 1, 2012, Morgan Stanley Spectrum Currency and Commodity L.P. (“Spectrum Currency and Commodity”), allocated a portion of their capital to the Master. Emerging CTA purchased an interest in the Master with cash equal to $3,000,000, and Spectrum Currency and Commodity purchased an interest in the Master with cash equal to $3,355,672. The Master permits commodity pools managed now or in the future by The Cambridge Strategy (Asset Management) Limited (the “Advisor”) using the Asian Markets Alpha Programme and the Emerging Markets Alpha Programme, the Advisor’s proprietary, systematic trading systems, to invest together in one trading vehicle.

During the year ended December 31, 2014, the Master’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. During prior periods included in this report, Citigroup Global Markets Inc. (“CGM”) also served as commodity broker.

The Master operates under a structure where its investors consist of Emerging CTA and Spectrum Currency and Commodity (each a “Feeder”, and collectively the “Funds”). Emerging CTA and Spectrum Currency and Commodity owned approximately 68.5% and 31.5% of the Master at December 31, 2014, respectively. Emerging CTA and Spectrum Currency and Commodity owned approximately 69.9% and 30.1% of the Master at December 31, 2013, respectively.

The Master will be liquidated under certain circumstances as defined in the limited partnership agreement of the Master (the “Limited Partnership Agreement”).

Master’s Fair Value Measurements.    Fair value is defined as the price 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. GAAP also requires the use of judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. The General Partner has concluded that, based on available information in the marketplace, the Master’s Level 1 assets and liabilities are actively traded.

The Master will separately present purchases, sales, issuances, and settlements in its reconciliation of Level 3 fair value measurements (i.e., to present such items on a gross basis rather than on a net basis), and makes disclosures regarding the level of disaggregation and the inputs and valuation techniques used to measure fair value for measurements that fall within either Level 2 or Level 3 of the fair value hierarchy as required under GAAP.

The Master considers prices for exchange-traded commodity futures, forwards, swaps and option contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forwards, swaps and certain options contracts for which market quotations are not readily available are priced by broker-dealers that derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the years ended December 31, 2014 and December 31, 2013, the Master did not hold any derivative instruments that were based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) or 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). During the years ended December 31, 2014 and December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.

The Master does not isolate that portion of the results of operations arising from the effect of changes in foreign exchange rates on investments from fluctuations from changes in market prices of investments held. Such fluctuations are included in net gain (loss) on investments in the Statements of Income and Expenses.

GAAP provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements and requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Master’s financial statements to

Cambridge Master Fund L.P.

Notes to Financial Statements

December 31, 2014

determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the Master level not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current year. The General Partner has concluded that no provision for income tax is required in the Master’s financial statements.

The Master files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The 2012 through 2014 tax years remain subject to examination by U.S. federal and most state tax authorities. The General Partner does not believe that there are any uncertain tax positions that require recognition of a tax liability.

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, MS&Co. or CGM, 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 under certain circumstances defined in the Management Agreement.

Prior to and during part of the third quarter of 2013, the Master was party to a Customer Agreement with CGM (the “CGM Customer Agreement”). During the third quarter of 2013, the Master entered into a Customer Agreement with MS&Co. (the “MS&Co. Customer Agreement”) and terminated the CGM Customer Agreement. During the second quarter of 2013, the Master also entered into a foreign exchange brokerage account agreement with MS&Co.

Under the CGM Customer Agreement, CGM provided services to the Master, including, among other things, the execution and clearing of transactions for the Master’s account in accordance with orders placed by the Advisor. All exchange, clearing, service, user, give-up, floor brokerage and National Futures Association (“NFA”) fees (collectively the “CGM clearing fees”) were borne by the Master and allocated to the Funds. All other fees including CGM’s direct brokerage fees were borne by the Funds. During the term of the CGM Customer Agreement, all of the Master’s assets were deposited in the Master’s account at CGM. The Master’s cash was deposited by CGM in segregated bank accounts to the extent required by Commodity Futures Trading Commission regulations.

Under the MS&Co. 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 NFA fees (collectively the “MS&Co. clearing fees” and together with the CGM clearing fees, the “clearing fees”) are borne by the Master and allocated to the Funds. All other fees are borne by the Funds. All of the Master’s assets are deposited in the Master’s account at MS&Co. The Master’s cash is deposited by MS&Co. in segregated bank accounts to the extent required by Commodity Futures Trading Commission regulations. At December 31, 2014 and December 31, 2013, the amount of cash held by the Master for margin requirements was $9,794,931 and $7,040,583, respectively. The MS&Co. Customer Agreement may generally be terminated upon notice by either party.

For the period April 1, 2014 to September 30, 2014, Spectrum Currency and Commodity paid MS&Co. a flat rate brokerage fee of 1/12 of 3.6% per month (a 3.6% annual rate), and prior to that this fee was charged at a flat rate of 1/12 of 4.6% per month (a 4.6% annual rate). For the period October 1, 2014 to December 31, 2014, Spectrum Currency and Commodity pays an ongoing placement agent fee to Morgan Stanley Wealth Management at a flat rate of 1/12 of 2% per month (a 2% annual rate) of the net assets of Spectrum Currency and Commodity allocated to the Advisor as of the first day of each month. Such fee includes clearing fees that are charged to the Master, therefore, the Master receives monthly expense reimbursements on clearing fees from MS&Co. incurred during such month, as shown on the Statements of Income and Expenses as expense reimbursements, based on the beginning of the month Partners’ capital allocation percentage of Spectrum Currency and Commodity in the Master.

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 MS&Co. Customer Agreement gives, and the CGM Customer Agreement gave, the Master the legal right to net unrealized gains and losses on open futures and forwards contracts. The Master nets, for financial reporting purposes, the unrealized gains and losses on open futures and open forward contracts on the Statements of Financial Condition as the criteria under Accounting Standards Codification 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 notional values of currency forward contracts traded for the years ended December 31, 2014 and December 31, 2013 were $2,127,047,182 and $1,482,257,366, respectively.

On January 1, 2013, the Master adopted ASU 2011-11, “Disclosure about Offsetting Assets and Liabilities” and ASU 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities”. ASU 2011-11 created a new disclosure requirement about the nature of an entity’s rights to setoff and the related arrangements associated with its financial instruments and derivative instruments, while ASU 2013-01 clarified the types of instruments and transactions that are subject to the offsetting disclosure requirements established by ASU 2011-11. Entities are required to disclose both gross information and net

information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of these disclosures is to facilitate comparison between those entities that prepare their financial statements on the basis of GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. The new guidance did not have a significant impact on the Master’s financial statements.

The following tables summarize the valuation of the Master’s investments as of December 31, 2014 and December 31, 2013.

The following tables indicate the gross fair values of derivative instruments of forward contracts as separate assets and liabilities as of December 31, 2014 and December 31, 2013.

Subscriptions are accepted monthly from investors and they become limited partners on the first day of the month after their subscription is processed. 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 day (the “Redemption Date”) after a request for redemption has been made to the General Partner at least three business 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.

Ratios to average net assets for the years ended December 31, 2014 and 2013, and for the period ended December 31, 2012 were as follows:

The above ratios may vary for individual investors based on the timing of capital transactions during the period. Additionally, these ratios are calculated for the limited partner class using the limited partners’ share of income, expenses and average net assets.

Notes to Financial Statements

December 31, 2014

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, 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, swap and option 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 100% of the Master’s contracts are traded OTC.

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 a market risk equal to the value of futures and forward contracts purchased 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 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 had credit risk and concentration risk during the reporting period and prior periods, as MS&Co. and/or CGM or their affiliates were the 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. and/or CGM, the Master’s counterparty is an exchange or clearing organization. The Master continues to be subject to such risks with respect to MS&Co.

The General Partner monitors and attempts to control 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 analyze statistically 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.
