3.  Related Party Transactions

The Partnership’s cash is on deposit with MSSB and MS&Co. in Futures Interest trading accounts to meet margin requirements as needed.  At each month end, MSSB pays the Partnership interest income on 80% of the funds on deposit with the commodity broker at a rate equal to the monthly average of the 4-week U.S. Treasury bill discount rate during such month.  MSSB retains any interest earned in excess of the interest paid by MSSB to the Partnership.  For purposes of such interest payments, net assets do not include monies owed to the Partnership on Futures Interests.  The Partnership pays brokerage fees to MS&Co.

4.  Financial Instruments

The Partnership trades Futures Interests.  Futures and forwards represent contracts for delayed delivery of an instrument at a specified date and price.  Futures Interests are open commitments until settlement date, at which time they are realized.  They are valued at fair value, generally on a daily basis, and the unrealized gains and losses on open contracts (the difference between contract trade price and market price) are reported in the Statements of Financial Condition as a net unrealized gain or loss on open contracts.  The resulting net change in unrealized gains and losses is reflected in the net change in unrealized trading profit (loss) on open contracts from one period to the next on the Statements of Income and Expenses.  The fair value of exchange-traded futures, options and forward contracts is determined by the various futures 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

- 10 -

MORGAN STANLEY SMITH BARNEY SPECTRUM CURRENCY L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

approximately 3:00 P.M. (E.T.) of 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 inputs, 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.  Risk arises from changes in the value of these contracts and the potential inability of counterparties to perform under the terms of the contracts.  There are numerous factors which may significantly influence the fair value of these contracts, including interest rate volatility.

The Partnership may buy or write put and call options through listed exchanges and the over-the-counter market.  The buyer of an option has the right to purchase (in the case of a call option) or sell (in the case of a put option) a specified quantity of a specific Futures Interest on the underlying assets at a specified price prior to or on a specified expiration date.  The writer of an option is exposed to the risk of loss if the fair value of the Futures Interest on the underlying asset declines (in the case of a put option) or increases (in the case of a call option).  The writer of an option can never profit by more than the premium paid by the buyer but can potentially lose an unlimited amount.

Premiums received/premiums paid from writing/purchasing options are recorded as liabilities/assets on the Statements of Financial Condition and are subsequently adjusted to fair values.  The difference between the fair value of the option and the premiums received/premiums paid is treated as an unrealized gain or loss.

- 11 -

MORGAN STANLEY SMITH BARNEY SPECTRUM CURRENCY L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The fair value of exchange-traded contracts is based on the settlement price quoted by the exchange on the day with respect to which fair value is being determined.  If an exchange-traded contract could not have been liquidated on such day due to the operation of daily limits or other rules of the exchange, the settlement price will be equal to the settlement price on the first subsequent day on which the contract could be liquidated.

The Partnership’s contracts are accounted for on a trade-date basis and marked to market on a daily basis.  The Partnership accounts for its derivative investments as described in Note 5.  Derivatives and Hedging as required by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC” or the “Codification”).  A derivative is defined as a financial instrument or other contract that has all three of the following characteristics:

1)   a) One or more “underlyings” and b) one or more “notional amounts” or payment provisions or both;

2)   Requires no initial net investment or a smaller initial net investment than would be required for other types of contracts that would be expected to have a similar response relative to changes in market factors; and

3)   Terms that require or permit net settlement.

Generally, derivatives include futures, forwards, swaps or options contracts, and other financial instruments with similar characteristics such as caps, floors, and collars.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The net unrealized gains on open contracts, reported as a component of “Trading Equity” on the Statements of Financial Condition, and their longest contract maturities were as follows:

	Net Unrealized Gains on Open Contracts			Longest Maturities
Date	Exchange-Traded	Off-Exchange-Traded	Total	Exchange-Traded	Off-Exchange-Traded

Dec. 31, 2010	74,100	1,044,336	1,118,436	Mar. 2011	Mar. 2011

The Partnership has credit risk associated with counterparty nonperformance.  As of the date of the financial statements, the credit risk associated with the instruments in which the Partnership trades is limited to the unrealized gain amounts reflected in the Partnership’s Statements of Financial Condition.

The Partnership also has credit risk because MS&Co. and/or MSCG acts as the futures commission merchant or the counterparty, with respect to most of the Partnership’s assets. Exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are marked to market on a daily basis, with variations in value settled on a daily basis. MS&Co., as a commodity broker for the Partnership’s exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts, is required, pursuant to regulations of the Commodity Futures Trading Commission (“CFTC”), to segregate from their own assets, and for the sole benefit of its commodity customers, all funds held by it with respect to exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts, including an amount equal to the net unrealized losses on all open exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts, which funds, in the aggregate, totaled $38,746,658 and $47,998,757 at

-  13 -

MORGAN STANLEY SMITH BARNEY SPECTRUM CURRENCY L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

September 30, 2011, and December 31, 2010, respectively.  With respect to the Partnership’s off-exchange-traded forward currency contracts and forward currency options contracts, there are no daily settlements of variation in value, nor is there any requirement that an amount equal to the net unrealized gains (losses) on such contracts be segregated.  However, the Partnership is required to meet margin requirements equal to the net unrealized loss on open forward currency contracts in the Partnership accounts with the counterparty, which is accomplished by daily maintenance of the cash balance in a custody account held at MSSB for the benefit of MS&Co. With respect to those off-exchange-traded forward currency contracts, the Partnership is at risk to the ability of MS&Co., the sole counterparty on all such contracts, to perform. With respect to those off-exchange-traded forward currency options contracts, the Partnership is at risk to the ability of MSCG, the sole counterparty on all such contracts, to perform.   The Partnership has a netting agreement with each counterparty.  These agreements, which seek to reduce both the Partnership’s and the counterparties’ exposure on off-exchange-traded forward currency contracts, including options on such contracts, should materially decrease the Partnership’s credit risk in the event of MS&Co.’s or MSCG’s bankruptcy or insolvency.

The futures, forwards and options traded by the Partnership involve varying degrees of related market risk.  Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership’s open positions, and consequently in its earnings, whether realized or unrealized, and cash flow.  Gains and losses on open positions of exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are settled daily through variation margin.  Gains and losses on off-exchange-traded forward currency contracts are settled upon termination of the contract.  Gains and losses on off-

MORGAN STANLEY SMITH BARNEY SPECTRUM CURRENCY L.P.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

exchange-traded forward currency options contracts are settled on an agreed-upon settlement price.  However, the Partnership is required to meet margin requirements equal to the net unrealized loss on open forward currency contracts in the Partnership’s accounts with the counterparty, which is accomplished by daily maintenance of the cash balance in a custody account held at MSSB for the benefit of MS&Co.

5.  Derivatives and Hedging

The Partnership’s objective is to profit from speculative trading in Futures Interests.  Therefore, the Trading Advisors for the Partnership will take speculative positions in Futures Interests where they feel the best profit opportunities exist for their trading strategy.  As such, the average number of contracts outstanding in absolute quantities (the total of the open long and open short positions) has been presented as a part of the volume disclosure, as position direction is not an indicative factor in such volume disclosures.  With regard to foreign currency forward trades, each notional quantity amount has been converted to an equivalent contract based upon an industry convention.

The following tables summarize the valuation of the Partnership’s investments as of September 30, 2011 and December 31, 2010, respectively.

6.  Fair Value Measurements and Disclosures

Financial instruments are carried at fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  Assets and liabilities carried at fair value are classified and disclosed in the following three levels: Level 1 - unadjusted quoted market prices in active markets for identical assets and liabilities; Level 2 - inputs other than unadjusted quoted market prices that are observable for the asset or liability, either directly or indirectly (including unadjusted quoted market prices for similar investments, interest rates, credit risk); and Level 3 - unobservable inputs for the asset or liability (including the Partnership’s own assumptions used in determining the fair value of investments).

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy.  In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.  The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment.

The Partnership’s assets and liabilities measured at fair value on a recurring basis are summarized in the following tables by the type of inputs applicable to the fair value measurements.

7.  Other Pronouncements

In May 2011, FASB issued Accounting Standards Update (“ASU”) 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in accounting principles generally accepted in the United States of America (“U.S. GAAP”) and International Financial Reporting Standards (“IFRSs”). The amendments within this ASU change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements to eliminate unnecessary wording differences between U.S. GAAP and IFRSs. However, some of the amendments clarify the FASB’s intent about the application of existing fair value measurement requirements and other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The ASU is effective for annual and interim periods beginning after December 15, 2011 for public entities.  This new guidance is not expected to have a material impact on the Partnership’s financial statements.

8.  Restricted and Unrestricted Cash

As reflected on the Partnership’s Statements of Financial Condition, restricted cash equals the cash portion of assets on deposit to meet margin requirements plus the cash required to offset unrealized losses on foreign currency forwards and options and offset losses on only offset London Metal Exchange positions.  All of these amounts are maintained separately.  Cash that is not classified as restricted cash is therefore classified as unrestricted cash.

9.  Income Taxes

No provision for income taxes has been made in the accompanying financial statements, as partners are individually responsible for reporting income or loss based upon their respective share of the Partnership’s revenues or expenses for income tax purposes. The Partnership files U.S. federal and state tax returns.

This guidance issued by the FASB on income taxes clarifies the accounting for uncertainty in income taxes recognized in the Partnership's financial statements, and prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken.  The Partnership has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements as of September 30, 2011.  If applicable, the Partnership recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in other expenses in the Statements of Income and Expenses.  Generally, the 2008 through 2010 tax years remain subject to examination by U.S. federal and most state tax authorities.  No income tax returns are currently under examination.

10.  Subsequent Events

Management of Ceres performed its evaluation of subsequent events through the date of filing, and has determined that there were no subsequent events requiring adjustment of or disclosure in the financial statements other than these disclosed below.

NOTES TO FINANCIAL STATEMENTS (CONCLUDED)

As of January 2, 2012, the General Partner will change the trading strategy of the Partnership to a strategy in which the trading advisors employ proprietary trading models and methodologies that seek to identify favorable price relationships between and among various global currency and commodity markets through the analysis of technical market information.  The Partnership will aim to achieve capital appreciation through speculative trading, directly and indirectly, in U.S. and international markets for currencies, agricultural and energy products and precious and base metals.  The Partnership may employ futures, options on futures, and forward contracts in those markets.  In implementing this new trading strategy, the General Partner has decided to change the name of the Partnership and to make certain changes to the Trading Advisors managing the assets on behalf of the Partnership.  Effective January 1, 2012, the Partnership’s name will change from “Morgan Stanley Smith Barney Spectrum Currency L.P.” to “Morgan Stanley Smith Barney Spectrum Currency and Commodity L.P.”  In respect of the Trading Advisors, the General Partners will remove the following Trading Advisors from the Partnership as of December 31, 2011: JWH and Sunrise.  Consequently, each of JWH and Sunrise will cease all futures interests trading on behalf of the Partnership as of that date.  The General partners also has determined to add the following two new trading advisors to manage the assets of the Partnership as of January 1, 2012: Flintlock Capital Asset Management, LLC and Krom River Investment Management (Cayman) Limited (together with its affiliate, Krom River Trading AG).

Item 2.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS

OF OPERATIONS

Liquidity.  The Partnership deposits its assets with MSSB as non-clearing commodity broker, and MS&Co. as its clearing commodity broker in separate futures, forward and options trading accounts established for each Trading Advisor.  Such assets are used as margin to engage in trading and may be used as margin solely for the Partnership’s trading. The assets are held in either non-interest bearing bank accounts or in securities and instruments permitted by the CFTC for investment of customer segregated or secured funds.  Since the Partnership’s sole purpose is to trade in futures, forwards and options, it is expected that the Partnership will continue to own such liquid assets for margin purposes.

The Partnership’s investment in futures, forwards and options may, from time to time, be illiquid.  Most U.S. futures exchanges limit fluctuations in prices during a single day by regulations referred to as “daily price fluctuation limits” or “daily limits.”  Trades may not be executed at prices beyond the daily limit.  If the price for a particular futures or options contract has increased or decreased by an amount equal to the daily limit, positions in that futures or options contract can neither be taken nor liquidated unless traders are willing to effect trades at or within the limit. Futures prices have occasionally moved the daily limit for several consecutive days with little or no trading.  These market conditions could prevent the Partnership from promptly liquidating its futures or options contracts and result in restrictions on redemptions.

There is no limitation on daily price moves in trading forward contracts on foreign currencies.  The markets for some world currencies have low trading volume and are illiquid, which may prevent the Partnership from

- 23 -

trading in potentially profitable markets or prevent the Partnership from promptly liquidating unfavorable positions in such markets, subjecting it to substantial losses.  Either of these market conditions could result in restrictions on redemptions.  For the periods covered by this report, illiquidity has not materially affected the Partnership’s assets.

There are no known material trends, demands, commitments, events, or uncertainties at the present time that are reasonably likely to result in the Partnership’s liquidity increasing or decreasing in any material way.

Capital Resources.  The Partnership does not have, nor does it expect to have, any capital assets.  Redemptions of units of limited partnership interest (“Unit(s)”) in the future will affect the amount of funds available for investments in futures, forwards and options in subsequent periods.  It is not possible to estimate the amount, and therefore the impact, of future outflows of Units.

There are no known material trends, favorable or unfavorable, that would affect, nor any expected material changes to, the Partnership’s capital resource arrangements at the present time.

Off-Balance Sheet Arrangements and Contractual Obligations.  The Partnership does not have any off-balance sheet arrangements, nor does it have contractual obligations or commercial commitments to make future payments that would affect its liquidity or capital resources.

- 24 -

Results of Operations

General.  The Partnership’s results depend on the Trading Advisors and the ability of each Trading Advisor’s trading program to take advantage of price movements in the futures, forward and options markets.  The following presents a summary of the Partnership’s operations for the three and nine month periods ended September 30, 2011 and 2010, and a general discussion of its trading activities during each period.  It is important to note, however, that the Trading Advisors trade in various markets at different times and that prior activity in a particular market does not mean that such market will be actively traded by the Trading Advisors or will be profitable in the future.  Consequently, the results of operations of the Partnership are difficult to discuss other than in the context of the Trading Advisors’ trading activities on behalf of the Partnership during the period in question.  Past performance is no guarantee of future results.

The Partnership’s results of operations set forth in the financial statements on pages 2 through 22 of this report are prepared in accordance with U.S. GAAP, which require the use of certain accounting policies that affect the amounts reported in these financial statements, including the following: the contracts the Partnership trades are accounted for on a trade-date basis and marked to market on a daily basis.  The difference between their original contract value and market value is recorded on the Statements of Income and Expenses as “Net change in unrealized trading profit (loss)” for open unrealized contracts, and recorded as “Realized trading profit (loss)” when open positions are closed out.  The sum of these amounts constitutes the Partnership’s trading results.  The market value of a futures contract is the settlement price on the exchange on which that futures contract is traded on a particular day.  The value of a foreign currency forward contract is based on the spot rate as of approximately 3:00 P.M. (E.T.) the close of the business day.  Interest income, as well as management fees, incentive fees, and brokerage fees of the Partnership are recorded on an accrual basis.

For the Three and Nine Months Ended September 30, 2011

The Partnership recorded total trading results including interest income totaling $1,507,343 and expenses totaling $656,096, resulting in net income of $851,247 for the three months ended September 30, 2011.  The Partnership’s net asset value per Unit increased from $8.84 on June 30, 2011 to $9.03 at September 30, 2011.

The most significant trading gains were achieved, during September, primarily from short positions in the South African rand versus the U.S. dollar as the value of the South African rand weakened relative to the U.S. dollar on speculation the South African central bank will signal further rate cuts after the International Monetary Fund lowered its global growth estimate. Additionally, gains were achieved in September from short positions in the Mexican peso versus the U.S. dollar as the value of the Mexican peso fell relative to the U.S. dollar on speculation the worldwide economic slump will curb demand for Mexican exports and slow investment into the country. During July, gains were achieved from long positions in the Swiss franc and Japanese yen versus the U.S. dollar as the value of these currencies rose against the U.S. dollar due to increased demand for “safe-haven” currencies amid investor concern about a weakening global economy. A portion of these gains for the quarter was offset by losses that were incurred, primarily during August, from long positions in the Australian dollar, and New Zealand dollar versus the U.S. dollar as the value of the U.S. dollar was boosted higher against these “commodity currencies” by “safe haven” demand following central bank intervention in the Japanese yen amid concerns related to the European debt crisis. The values of the Australian dollar and New Zealand were also weighed down by declining commodity prices.

The Partnership recorded total trading results including interest income totaling $(535,010) and expenses totaling $2,127,253, resulting in a net loss of $2,662,263 for the nine months ended September 30, 2011.  The

- 26 -

Partnership’s net asset value per Unit decreased from $9.57 on December 31, 2010 to $9.03 at September 30, 2011.

The most significant trading losses were incurred during May primarily from long positions in the South African rand versus the U.S. dollar as the value of this “commodity currency” fell in tandem with declining commodity prices. Additionally, losses were incurred during August from long positions in the Australian dollar, South African rand, and New Zealand dollar versus the U.S. dollar as the value of the U.S. dollar was boosted higher against these “commodity currencies” by “safe haven” demand following central bank intervention in the Japanese yen and amid concerns related to the European debt crisis. Losses were also incurred during March from long positions in the Japanese yen versus the U.S. dollar as the value of the Japanese yen fell relative to the U.S. dollar after the Bank of Japan and the G-7 successfully intervened in the foreign exchange markets to halt the yen’s rise. Additional losses were incurred during February from short positions in the South African rand, as the value of the U.S. dollar rose relative to this currency on optimism for the U.S. economy. A portion of the Partnership’s losses for the first nine months of the year was offset by gains, primarily during April, from long positions in the Swiss franc and Indian rupee versus the U.S. dollar as the value of these currencies rose against the U.S. dollar after better-than-expected corporate earnings reports and signs of global growth spurred demand for higher-yielding currencies. Additional gains were recorded during September from short positions in the Mexican peso versus the U.S. dollar as the value of the peso fell on speculation the worldwide economic slump will curb demand for Mexican exports and slow investment into that country. During July, gains were achieved from long positions in the Swiss franc versus the U.S. dollar as the value of the franc rose against the U.S. dollar due to increased demand for “safe-haven” currencies amid investor concern about a weakening global economy.

For the Three and Nine Months Ended September 30, 2010

The Partnership recorded total trading results including interest income totaling $498,200 and expenses totaling $848,114, resulting in a net loss of $349,914 for the three months ended September 30, 2010.  The Partnership’s net asset value per Unit decreased from $9.57 on June 30, 2010 to $9.51 at September 30, 2010.

The most significant trading losses of approximately 1.3%, 0.4%, and 0.3%, respectively, were incurred primarily during July from short positions in the euro, Swedish krona, and Canadian dollar versus the U.S. dollar as the value of these currencies rose against the U.S. dollar after the International Monetary Fund raised global growth forecasts, which boosted demand for higher-yielding currency assets. Additional losses were recorded during September from short positions in the euro and Swedish krona versus the U.S. dollar as the value of the U.S. dollar fell against these currencies amid renewed optimism regarding the global economic recovery, which diminished demand for the relative “safe haven” of the U.S. currency. Meanwhile, losses of approximately 0.3% were experienced primarily during August from long positions in the New Zealand dollar versus the U.S. dollar as the value of the U.S. dollar moved higher against the New Zealand dollar amid fears about global growth prospects. A portion of the Partnership’s losses for the quarter was offset by gains of approximately 0.9% achieved primarily during September from long positions in the Australian dollar versus the U.S. dollar as the value of the Australian dollar appreciated to a 26-month high against the U.S. dollar amid speculation that the Reserve Bank of Australia might raise interest rates in October. Gains of approximately 0.7% were experienced primarily during July from long positions in the Japanese yen versus the U.S. dollar as the value of the U.S. dollar fell against the Japanese yen following downbeat comments about the U.S. credit rating and economic growth. During August, further gains were achieved as the value of the Japanese yen increased relative to the U.S. currency on speculation that reports

- 28 -

might show U.S. expansion decelerated, thereby spurring investors to unwind existing carry trades. Gains of approximately 0.6%, 0.5%, and 0.4%, respectively, were achieved primarily during September from long positions in the Singapore dollar, South African rand, and Swiss franc versus the U.S. dollar as the value of the U.S. dollar fell against these currencies amid the aforementioned renewed optimism regarding the global economic recovery, which reduced demand for the U.S. dollar as a “safe haven” currency. The value of the U.S. dollar continued to drop later in September on speculation that the U.S. Federal Reserve’s willingness to ease monetary policy further might diminish demand for U.S. currency assets.

The Partnership recorded total trading results including interest income totaling $(235,393) and expenses totaling $2,749,733, resulting in a net loss of $2,985,126 for the nine months ended September 30, 2010.  The Partnership’s net asset value per Unit decreased from $10.03 at December 31, 2009 to $9.51 at September 30, 2010.

The most significant trading losses of approximately 2.0% were incurred primarily during April and May from long positions in the Australian dollar versus the U.S. dollar and Japanese yen as the value of the Australian dollar declined against these currencies after Australian reports showed weak consumer confidence and the speculation that China's economy might be slowing diminished the appeal of growth-linked currencies. Additional losses of approximately 0.7% were incurred primarily during May from long positions in the Norwegian krone versus the U.S. dollar as the value of the Norwegian krone declined amid concern over the Greek government debt crisis, which reduced demand for higher-yielding currency assets. Losses of approximately 0.5% were recorded primarily during May and August from long positions in the New Zealand dollar versus the U.S. dollar amid concern over the Greek government debt crisis and global

- 29 -

growth prospects, which reduced investor demand for higher-yielding currency assets. Smaller losses of approximately 0.4% were experienced primarily during September from short positions in the British pound versus the U.S. dollar as the value of the U.S. dollar fell against the British pound amid renewed optimism regarding the global economic recovery, which diminished demand for the relative “safe haven” of the U.S. currency. A portion of the Partnership’s losses in the first nine months of the year was offset by gains of approximately 1.1% from long positions in the Japanese yen versus the U.S. dollar as the value of the Japanese yen increased relative to the U.S. dollar amid speculation that global economic growth might diminish, thus boosting “safe haven” demand for the Japanese currency. Further gains were experienced during August as the value of the Japanese yen increased relative to the U.S. dollar on speculation that reports might show U.S. expansion decelerated, thereby spurring investors to unwind existing carry trades. Gains of approximately 0.7% and 0.3%, respectively, were experienced from long positions in the Swedish krona and Mexican peso versus the U.S. dollar as the value of these currencies moved higher against the U.S. dollar, primarily during February and March, after signs of a global economic recovery caused investors to increase their risk appetite for higher-yielding currencies. Furthermore, the value of the Mexican peso moved higher at the end of March after Mexico’s Finance Ministry raised its forecast for the nation’s economic growth this year. Additionally, newly established short positions in the Swedish krona versus the U.S. dollar resulted in gains during May as the value of the Swedish krona fell amid worries about the stability of the Euro-Zone. Additional gains of approximately 0.4% were achieved, primarily during January and February, from short positions in the euro versus the U.S. dollar as the value of the euro was pressured lower on concern that Greece’s fiscal struggles might spread and hinder growth for the entire Euro-Zone. Further gains were achieved during May as the value of the euro continued to move lower against the U.S. currency after reports of political discord in Europe reignited worries about the stability of the region’s economy. Lastly, gains of

- 30 -

approximately 0.4% were experienced during May and September due to positions in the Swiss franc versus the U.S. dollar. During May, short positions in the Swiss franc versus the U.S. dollar resulted in gains as the value of the Swiss franc moved lower against the U.S. currency after reports of political discord in Europe reignited worries about the stability of the region’s economy. Meanwhile, in September, newly established long positions in the Swiss franc versus the U.S. dollar achieved gains as the value of the U.S. dollar fell against the Swiss franc on speculation that the U.S. Federal Reserve’s willingness to ease monetary policy further might diminish demand for U.S. currency assets.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Introduction

The Partnership is a commodity pool engaged primarily in the speculative trading of futures, forwards and options.  The market-sensitive instruments held by the Partnership are acquired for speculative trading purposes only and, as a result, all or substantially all of the Partnership’s assets are at risk of trading loss.  Unlike an operating company, the risk of market-sensitive instruments is inherent to the primary business activity of the Partnership.

The futures, forwards and options on such contracts traded by the Partnership involve varying degrees of related market risk.  Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership’s open positions, and consequently in its earnings, whether realized or unrealized, and cash flow.  Gains and losses on open positions of exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are settled daily through variation margin.

- 31 -

Gains and losses on off-exchange-traded forward currency contracts and forward currency options contracts are settled upon termination of the contract.  Gains and losses on off-exchange-traded forward currency options contracts are settled upon an agreed upon settlement date.  However, the Partnership is required to meet margin requirements equal to the net unrealized loss on open forward currency contracts in the Partnership accounts with the counterparty, which is accomplished by daily maintenance of the cash balance in a custody account held at MSSB for the benefit of MS&Co.

The Partnership’s total market risk may increase or decrease as it is influenced by a wide variety of factors, including, but not limited to, the diversification among the Partnership’s open positions, the volatility present within the markets, and the liquidity of the markets.

The face value of the market sector instruments held by the Partnership is typically many times the applicable margin requirements.  Margin requirements generally range between 2% and 15% of contract face value.  Additionally, the use of leverage causes the face value of the market sector instruments held by the Partnership typically to be many times the total capitalization of the Partnership.

The Partnership’s past performance is no guarantee of its future results.  Any attempt to numerically quantify the Partnership’s market risk is limited by the uncertainty of its speculative trading.  The Partnership’s speculative trading and use of leverage may cause future losses and volatility (i.e., “risk of ruin”) that far exceed the Partnership’s experience to date under the “Partnership’s Value at Risk in Different Market Sectors” section and significantly exceed the Value at Risk (“VaR”) tables disclosed.

Limited partners will not be liable for losses exceeding the current net asset value of their investment.

- 32 -

Quantifying the Partnership’s Trading Value at Risk

The following quantitative disclosures regarding the Partnership’s market risk exposures contain “forward-looking statements” within the meaning of the safe harbor from civil liability provided for such statements by the Private Securities Litigation Reform Act of 1995 (set forth in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934).  All quantitative disclosures in this section are deemed to be forward-looking statements for purposes of the safe harbor, except for statements of historical fact.

The Partnership accounts for open positions on the basis of fair value accounting principles.  Any loss in the market value of the Partnership’s open positions is directly reflected in the Partnership’s earnings and cash flow.

The Partnership’s risk exposure in the market sectors traded by the Trading Advisors is estimated below in terms of VaR.  Prior to June 30, 2011, the Partnership estimated VaR using a model based upon historical simulation (with a confidence level of 99%) which involved constructing a distribution of hypothetical daily changes in the value of a trading portfolio.  The VaR model took into account linear exposures to risk including equity and commodity prices, interest rates, foreign exchange rates, and correlation among these variables. The hypothetical changes in portfolio value were based on daily percentage changes observed in key market indices or other market factors (“market risk factors”) to which the portfolio was sensitive.  The one-day 99% confidence level of the Partnership’s VaR corresponded to the negative change in portfolio value that, based on observed market risk factors, would have been exceeded once in 100 trading days, or one day in 100. VaR typically does not represent the worst case outcome.  Ceres used approximately four years of daily market data (1,000 observations) and re-valued its portfolio (using delta-gamma approximations) for each of the historical market moves that occurred over this time period.  This generated a probability distribution of daily “simulated

- 33 -

profit and loss” outcomes.  The VaR was the appropriate percentile of this distribution.  For example, the 99% one-day VaR would represent the 10th worst outcome from Ceres’ simulated profit and loss series.

The Partnership’s VaR computations were based on the risk representation of the underlying benchmark for each instrument or contract and did not distinguish between exchange and non-exchange dealer-based instruments.  They were also not based on exchange and/or dealer-based maintenance margin requirements.  VaR models, including the Partnership’s, are continually evolving as trading portfolios become more diverse and modeling techniques and systems capabilities improve.  Please note that the VaR model is used to numerically quantify market risk for historic reporting purposes only and is not utilized by either Ceres or the Trading Advisors in their daily risk management activities.  Please further note that VaR as described above may not be comparable to similarly-titled measures used by other entities.

Starting with the third quarter 2011, exchange maintenance margin requirements have been used by the Partnership as the measure of its use.  Maintenance margin requirements are set by exchanges to equal or exceed the maximum losses reasonably expected to be incurred in the fair value of any given contract in 95% - 99% of any one-day interval.  Maintenance margin has been used rather than the more generally available initial margin, because initial margin includes a credit risk component, which is not relevant to VaR.

The Partnership’s Value at Risk in Different Market Sectors

The following tables indicate the trading VaR associated with the Partnership’s open positions by  market category as of September 30, 2011 and the highest, lowest and average values during the three months ended September 30, 2011.  All open position trading risk exposures of the Partnership have been included in

The following table indicates the VaR associated with the Partnership’s open positions as a percentage of total Partner’s Capital by primary market risk category at December 31, 2010.  At December 31, 2010, the Partnership’s total capitalization was approximately $48 million.

Primary Market	December 31, 2010
Risk Category	VaR
Currency	(1.13)%

The VaR for a market category represents the one-day downside risk for the aggregate exposures associated with this market category.  Because the business of the Partnership is the speculative trading of futures, forwards and options, the composition of its trading portfolio can change significantly over any given time period, or even within a single trading day.  Such change could positively or negatively materially impact market risk as measured by VaR.

The table below supplements the quarter-end VaR set forth above by presenting the Partnership’s high, low, and average VaR, as a percentage of total net assets for the four quarter-end reporting period from January 1, 2010 through December 31, 2010.

Limitations on Value at Risk as an Assessment of Market Risk

VaR models permit estimation of a portfolio’s aggregate market risk exposure, incorporating a range of varied market risks, reflect risk reduction due to portfolio diversification or hedging activities, and can cover a wide range of portfolio assets. However, VaR risk measures should be viewed in light of the methodology’s limitations, which include, but may not be limited to the following:

·   past changes in market risk factors will not always result in accurate predictions of the distributions and correlations of future market movements;

·   changes in portfolio value caused by market movements may differ from those of the VaR model;

·   VaR results reflect past market fluctuations applied to current trading positions while future risk depends on future positions;

·   VaR using a one-day time horizon does not fully capture the market risk of positions that cannot be liquidated or hedged within one day; and

·   the historical market risk factor data used for VaR estimation may provide only limited insight into losses that could be incurred under certain unusual market movements.

In addition, the VaR tables above, as well as the past performance of the Partnership, give no indication of the Partnership’s potential “risk of ruin.”

The VaR tables provided present the results of the Partnership’s VaR for each of the Partnership’s market risk exposures at September 30, 2011 and December 31, 2010, and for the three months from July 1, 2011 through September 30, 2011 and twelve months from January 1, 2010 through December 31, 2010, respectively.  VaR is not necessarily representative of the Partnership’s historic risk, nor should it be used to predict the Partnership’s future financial performance or its ability to manage or monitor risk.  There can be no assurance that the Partnership’s actual losses on a particular day will not exceed the VaR amounts indicated above or that such losses will not occur more than once in 100 trading days.

Non-Trading Risk

The Partnership has non-trading market risk on its foreign cash balances not needed for margin.  These balances and any market risk they may represent are immaterial.

The Partnership also maintains a substantial portion of its available assets in unrestricted cash at MSSB; as of September 30, 2011, such amount was equal to approximately 96% of the Partnership’s net asset value.  A decline in short-term interest rates would result in a decline in the Partnership’s cash management income. This cash flow risk is not considered to be material.

Materiality, as used throughout this section, is based on an assessment of reasonably possible market movements and any associated potential losses, taking into account the leverage, optionality, and multiplier features of the Partnership’s market-sensitive instruments, in relation to the Partnership’s net assets.

Qualitative Disclosures Regarding Primary Trading Risk Exposures

The following qualitative disclosures regarding the Partnership’s market risk exposures - except for (A) those disclosures that are statements of historical fact and (B) the descriptions of how the Partnership manages its primary market risk exposures - constitute forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. The Partnership’s primary market risk exposures, as well as the strategies used and to be used by Ceres and the Trading Advisors for managing such exposures, are subject to numerous uncertainties, contingencies and risks, any one of which could cause the actual results of the Partnership’s risk controls to differ materially from the objectives of such strategies.  Government interventions, defaults and expropriations, illiquid markets, the emergence of dominant fundamental factors, political upheavals, changes in historical price relationships, an influx of new market participants, increased regulation, and many other factors could result in material losses, as well as in material changes to the risk exposures and the risk management strategies of the Partnership.  Investors must be prepared to lose all or substantially all of their investment in the Partnership.

Qualitative Disclosures Regarding Means of Managing Risk Exposure

The Partnership and the Trading Advisors, separately, attempt to manage the risk of the Partnership’s open positions in essentially the same manner in all market categories traded. Ceres attempts to manage market exposure by diversifying the Partnership’s assets among different market sectors and trading approaches through the selection of the Trading Advisors and by daily monitoring their performance.  In addition, the Trading Advisors establish diversification guidelines, often set in terms of the maximum margin to be committed to positions in any one market sector or market-sensitive instrument.

Ceres monitors and controls the risk of the Partnership’s non-trading instrument, cash. Cash is the only Partnership investment directed by Ceres, rather than the Trading Advisors.

Item 4.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the management of Ceres, at the time this quarterly report was filed, Ceres’ President (Ceres’ principal executive officer) and Chief Financial Officer (Ceres’ principal financial officer) have evaluated the effectiveness of the design and operation of the Partnership’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of September 30, 2011.  The Partnership’s disclosure controls and procedures are designed to provide reasonable assurance that information the Partnership is required to disclose in the reports that the Partnership files or submits under the Exchange Act are recorded, processed and summarized and reported within the time period specified in the applicable rules and forms.  Based on this evaluation, the President and Chief Financial Officer of Ceres have concluded that the disclosure controls and procedures of the Partnership were effective at September 30, 2011.

Changes in Internal Control over Financial Reporting

There have been no changes during the period covered by this quarterly report in the Partnership’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act)

that have materially affected or are reasonably likely to materially affect the Partnership’s internal control over financial reporting.

-39-

Limitations on the Effectiveness of Controls

Any control system, no matter how well designed and operated, can provide reasonable (not absolute) assurance that its objectives will be met.  Furthermore, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

Fair Value Measurements and Disclosures [Abstract]

Fair Value Measurements and Disclosures

6.  Fair Value Measurements and Disclosures

Financial instruments are carried at fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  Assets and liabilities carried at fair value are classified and disclosed in the following three levels: Level 1 - unadjusted quoted market prices in active markets for identical assets and liabilities; Level 2 - inputs other than unadjusted quoted market prices that are observable for the asset or liability, either directly or indirectly (including unadjusted quoted market prices for similar investments, interest rates, credit risk); and Level 3 - unobservable inputs for the asset or liability (including the Partnership's own assumptions used in determining the fair value of investments).

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy.  In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.  The Partnership's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment.

The Partnership's assets and liabilities measured at fair value on a recurring basis are summarized in the following tables by the type of inputs applicable to the fair value measurements.

Restricted and Unrestricted Cash [Abstract]

Restricted and Unrestricted Cash

8.  Restricted and Unrestricted Cash

As reflected on the Partnership's Statements of Financial Condition, restricted cash equals the cash portion of assets on deposit to meet margin requirements plus the cash required to offset unrealized losses on foreign currency forwards and options and offset losses on only offset London Metal Exchange positions.  All of these amounts are maintained separately.  Cash that is not classified as restricted cash is therefore classified as unrestricted cash.

Income Taxes [Abstract]

Income Taxes

9.  Income Taxes

No provision for income taxes has been made in the accompanying financial statements, as partners are individually responsible for reporting income or loss based upon their respective share of the Partnership's revenues or expenses for income tax purposes. The Partnership files U.S. federal and state tax returns.

This guidance issued by the FASB on income taxes clarifies the accounting for uncertainty in income taxes recognized in the Partnership's financial statements, and prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken.  The Partnership has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements as of September 30, 2011.  If applicable, the Partnership recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in other expenses in the Statements of Income and Expenses.  Generally, the 2008 through 2010 tax years remain subject to examination by U.S. federal and most state tax authorities.  No income tax returns are currently under examination.

7.  Other Pronouncements

In May 2011, FASB issued Accounting Standards Update (“ASU”) 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in accounting principles generally accepted in the United States of America (“U.S. GAAP”) and International Financial Reporting Standards (“IFRSs”).  The amendments within this ASU change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements to eliminate unnecessary wording differences between U.S. GAAP and IFRSs. However, some of the amendments clarify the FASB's intent about the application of existing fair value measurement requirements and other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The ASU is effective for annual and interim periods beginning after December 15, 2011 for public entities.  This new guidance is not expected to have a material impact on the Partnership's financial statements.

Financial Instruments

4.  Financial Instruments

The Partnership trades Futures Interests.  Futures and forwards represent contracts for delayed delivery of an instrument at a specified date and price.  Futures Interests are open commitments until settlement date, at which time they are realized.  They are valued at fair value, generally on a daily basis, and the unrealized gains and losses on open contracts (the difference between contract trade price and market price) are reported in the Statements of Financial Condition as a net unrealized gain or loss on open contracts.  The resulting net change in unrealized gains and losses is reflected in the net change in unrealized trading profit (loss) on open contracts from one period to the next on the Statements of Income and Expenses.  The fair value of exchange-traded futures, options and forward contracts is determined by the various futures 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.) of 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 inputs, 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.  Risk arises from changes in the value of these contracts and the potential inability of counterparties to perform under the terms of the contracts.  There are numerous factors which may significantly influence the fair value of these contracts, including interest rate volatility.

The Partnership may buy or write put and call options through listed exchanges and the over-the-counter market.  The buyer of an option has the right to purchase (in the case of a call option) or sell (in the case of a put option) a specified quantity of a specific Futures Interest on the underlying assets at a specified price prior to or on a specified expiration date.  The writer of an option is exposed to the risk of loss if the fair value of the Futures Interest on the underlying asset declines (in the case of a put option) or increases (in the case of a call option).  The writer of an option can never profit by more than the premium paid by the buyer but can potentially lose an unlimited amount.

Premiums received/premiums paid from writing/purchasing options are recorded as liabilities/assets on the Statements of Financial Condition and are subsequently adjusted to fair values.  The difference between the fair value of the option and the premiums received/premiums paid is treated as an unrealized gain or loss.

The fair value of exchange-traded contracts is based on the settlement price quoted by the exchange on the day with respect to which fair value is being determined.  If an exchange-traded contract could not have been liquidated on such day due to the operation of daily limits or other rules of the exchange, the settlement price will be equal to the settlement price on the first subsequent day on which the contract could be liquidated.

The Partnership's contracts are accounted for on a trade-date basis and marked to market on a daily basis.  The Partnership accounts for its derivative investments as described in Note 5.  Derivatives and Hedging as required by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC” or the “Codification”).  A derivative is defined as a financial instrument or other contract that has all three of the following characteristics:

1)   a) One or more “underlyings” and b) one or more “notional amounts” or payment provisions or both;

2)   Requires no initial net investment or a smaller initial net investment than would be required for other types of contracts that would be expected to have a similar response relative to changes in market factors; and

3)   Terms that require or permit net settlement.

Generally, derivatives include futures, forwards, swaps or options contracts, and other financial instruments with similar characteristics such as caps, floors, and collars.

The net unrealized gains on open contracts, reported as a component of “Trading Equity” on the Statements of Financial Condition, and their longest contract maturities were as follows:

	Net Unrealized Gains on Open Contracts			Longest Maturities
Date	Exchange-Traded	Off-Exchange-Traded	Total	Exchange-Traded	Off-Exchange-Traded
	$	$	$
Sep. 30, 2011	106,548	1,276,004	1,382,552	Dec. 2011	Dec. 2011
Dec. 31, 2010	74,100	1,044,336	1,118,436	Mar. 2011	Mar. 2011

The Partnership has credit risk associated with counterparty nonperformance.  As of the date of the financial statements, the credit risk associated with the instruments in which the Partnership trades is limited to the unrealized gain amounts reflected in the Partnership's Statements of Financial Condition.

The Partnership also has credit risk because MS&Co. and/or MSCG acts as the futures commission merchant or the counterparty, with respect to most of the Partnership's assets. Exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are marked to market on a daily basis, with variations in value settled on a daily basis. MS&Co., as a commodity broker for the Partnership's exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts, is required, pursuant to regulations of the Commodity Futures Trading Commission (“CFTC”), to segregate from their own assets, and for the sole benefit of its commodity customers, all funds held by it with respect to exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts, including an amount equal to the net unrealized losses on all open exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts, which funds, in the aggregate, totaled $38,746,658 and $47,998,757 at

September 30, 2011, and December 31, 2010, respectively.  With respect to the Partnership's off-exchange-traded forward currency contracts and forward currency options contracts, there are no daily settlements of variation in value, nor is there any requirement that an amount equal to the net unrealized gains (losses) on such contracts be segregated.  However, the Partnership is required to meet margin requirements equal to the net unrealized loss on open forward currency contracts in the Partnership accounts with the counterparty, which is accomplished by daily maintenance of the cash balance in a custody account held at MSSB for the benefit of MS&Co. With respect to those off-exchange-traded forward currency contracts, the Partnership is at risk to the ability of MS&Co., the sole counterparty on all such contracts, to perform. With respect to those off-exchange-traded forward currency options contracts, the Partnership is at risk to the ability of MSCG, the sole counterparty on all such contracts, to perform.   The Partnership has a netting agreement with each counterparty.  These agreements, which seek to reduce both the Partnership's and the counterparties' exposure on off-exchange-traded forward currency contracts, including options on such contracts, should materially decrease the Partnership's credit risk in the event of MS&Co.'s or MSCG's bankruptcy or insolvency.

The futures, forwards and options traded by the Partnership involve varying degrees of related market risk.  Market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and prices of financial instruments and commodities, factors that result in frequent changes in the fair value of the Partnership's open positions, and consequently in its earnings, whether realized or unrealized, and cash flow.  Gains and losses on open positions of exchange-traded futures, exchange-traded forward, and exchange-traded futures-styled options contracts are settled daily through variation margin.  Gains and losses on off-exchange-traded forward currency contracts are settled upon termination of the contract.  Gains and losses on off-exchange-traded forward currency options contracts are settled on an agreed-upon settlement price.  However, the Partnership is required to meet margin requirements equal to the net unrealized loss on open forward currency contracts in the Partnership's accounts with the counterparty, which is accomplished by daily maintenance of the cash balance in a custody account held at MSSB for the benefit of MS&Co.

The Partnership's objective is to profit from speculative trading in Futures Interests.  Therefore, the Trading Advisors for the Partnership will take speculative positions in Futures Interests where they feel the best profit opportunities exist for their trading strategy.  As such, the average number of contracts outstanding in absolute quantities (the total of the open long and open short positions) has been presented as a part of the volume disclosure, as position direction is not an indicative factor in such volume disclosures.  With regard to foreign currency forward trades, each notional quantity amount has been converted to an equivalent contract based upon an industry convention.
