Critical Accounting Policies

7. Critical Accounting Policies:

     Use of Estimates. The preparation of financial statements and accompanying notes in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and related disclosures of contingent assets and liabilities in the financial statements and accompanying notes. As a result, actual results could differ from these estimates.

     Partnership’s Investments. The Partnership values its investment in the Trading Company at its net asset value per unit as calculated by the Trading Company. The Trading Company values its investments as described in note 2 of the Trading Company’s notes to the annual financial statements as of December 31, 2010.

     Partnership’s and the Trading Company’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. Management has concluded that based on available information in the marketplace, the Trading Company Level 1 assets and liabilities are actively traded.

     GAAP also requires the need to use judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Partnership’s Level 2 assets and liabilities.

     The Partnership 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 make 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 Partnership values investments in the Trading Company where there are no other rights or obligations inherent within the ownership interest held by the Partnership based on the end of the day net asset value of the Trading Company (Level 2). The value of the Partnership’s investment in the Trading Company reflects its proportional interest in the Trading Company. As of and for the periods ended June 30, 2011 and December 31, 2010, the Partnership did not hold any derivative instruments that are based on unadjusted quoted prices in active markets for identical assets (Level 1) or priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3).

     The Trading Company considers prices for exchange-traded commodity futures, forwards and options contracts to be based on unadjusted quoted prices in active markets for identical assets (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 who derive fair values for those assets from observable inputs (Level 2). As of and for the periods ended June 30, 2011 and December 31, 2010, the Trading Company did not hold any derivative instruments for which market quotations are not readily available, and are priced by broker-dealers who derive fair values for those assets from observable inputs (Level 2) or that are priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3).

     Futures Contracts. The Trading Company 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 if 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 Trading Company 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 Trading Company. When the contract is closed, the Trading Company 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, directly with the exchange on which the contracts are traded. Net realized gains (losses) and changes in net unrealized gains (losses) on futures contracts are included in the Statements of Income and Expenses and Changes in Members’ Capital.

     Forward Foreign Currency Contracts. Foreign currency contracts are those contracts where the Trading Company agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. Foreign currency contracts are valued daily, and the Trading Company’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 changes in net 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 and Changes in Members’ Capital.

     The Trading Company does not isolate the 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 and Changes in Members’ Capital.

     Options. The Trading Company may purchase and write (sell) both exchange listed and OTC options on commodities or financial instruments. An option is a contract allowing, but not requiring, its holder to buy (call) or sell (put) a specific or standard commodity or financial instrument at a specified price during a specified time period. The option premium is the total price paid or received for the option contract. When the Trading Company writes an option, the premium received is recorded as a liability in the Statements of Financial Condition and marked to market daily. When the Trading Company purchases an option, the premium paid is recorded as an asset in the Statements of Financial Condition and marked to market daily. Net realized gains (losses) and changes in net unrealized gains (losses) on options contracts are included in the Statements of Income and Expenses and Changes in Members’ Capital.

     Income Taxes. Income taxes have not been provided as each partner is individually liable for the taxes, if any, on its share of the Partnership’s 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 Partnership’s financial statements to 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 Partnership 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 concluded that no provision for income tax is required in the Partnership’s financial statements.

     The Partnership files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. In general the statute of limitations of the Partnership’s U.S. federal tax returns remains open three years after a tax return is filed. The statutes of limitations on the Partnership’s state and local tax returns may remain open for an additional year depending upon the jurisdiction. Management does not believe that there are any uncertain tax positions that require recognition of a tax liability.

     Subsequent Events. The General Partner evaluates events that occur after the balance sheet date but before financial statements are filed. Beginning August 1, 2011, Class Z units will be offered to certain employees of Morgan Stanley Smith Barney and its affiliates (and their family members). Class A, D and Class Z will each be referred to as a “Class” and collectively referred to as the “Classes”. The Class of Units that a Limited Partner receives upon a subsription will generally depend upon the amount invested in the Partnership, although the General Partner may determine to offer Units to investors at its discretion.

     Recent Accounting Pronouncements. In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU ”) 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards” (“ IFRS”). 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 IFRS. 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.

     Net Income (Loss) per Redeemable Unit. Net income (loss) per unit for each class is calculated in accordance with investment company guidance. See Note 2, “Financial Highlights”.
