The Partnership’s pro-rata The futures brokerage account agreements with MS&Co. give the Partnership and the Fund the legal right to net unrealized gains and losses on open futures and open forward contracts in the Statements of Financial Condition. The Fund nets, for financial reporting purposes, the unrealized gains and losses on open futures and open forward contracts in the Statements of Financial Condition as the criteria under ASC 210 - Balance Sheet Trading and transaction fees are based on the number of trades executed by the Advisor for the Fund and the Partnership’s percentage ownership of the Fund. All clearing fees paid to MS&Co. are borne by the Fund and allocated to the limited partners, including the Partnership. All of the commodity interests owned by the Fund are held for trading purposes. The monthly average number of futures contracts traded during the three months ended September 30, 2018 and 2017 were 1,351 and 2,591, respectively. The monthly average number of futures contracts traded during the nine months ended September 30, 2018 and 2017 were 1,386 and 2,580, respectively.

Investment in the Fund	6. Investment in the Fund: On March 1, 2005, the assets allocated to Aspect for trading were invested in Aspect Master, a limited partnership organized under the partnership laws of the State of New York. Aspect Master permits accounts managed by Aspect using Aspect’s Diversified Program, a proprietary, systematic trading system, to invest together in one trading vehicle. The General Partner is also the general partner of Aspect Master. Individual and pooled accounts currently managed by Aspect, including the Partnership, are permitted to be limited partners of Aspect Master. The General Partner and Aspect believe that trading through this structure should promote efficiency and economy in the trading process. On September 1, 2016, the assets allocated to PGR for trading were invested in PGR Master, a limited partnership organized under the partnership laws of the State of Delaware. PGR Master permitted accounts managed by PGR using its Mayfair Program, a proprietary, systematic trading system, to invest together in one trading vehicle. The General Partner was also the general partner of PGR Master. Individual and pooled accounts managed by PGR, including the Partnership, were permitted to be limited partners of PGR Master. The General Partner and PGR believed that trading through this structure would promote efficiency and economy in the trading process. Effective the close of business on December 31, 2017, the Partnership fully redeemed its investment in PGR Master. The General Partner is not aware of any other material changes to any of the trading programs discussed above or in Note 1, “Organization” during the fiscal quarter ended September 30, 2018. The Fund’s trading of futures, forward, swap and option contracts, if applicable, on commodities is done primarily on U.S. and foreign commodity exchanges. The Fund engaged in such trading through commodity brokerage accounts maintained with MS&Co. Generally, a limited partner in the Fund withdraws all or part of its capital contribution and undistributed profits, if any, from the Fund as of the end of any month (the “Redemption Date”) after a request has been made to the General Partner at least three days in advance of the Redemption Date. Such withdrawals are classified as a liability when the limited partner elects to redeem and informs the Fund. However, a limited partner may request a withdrawal as of the end of any day if such request is received by the General Partner at least three days in advance of the proposed withdrawal day. Management fees, General Partner fees, ongoing selling agent fees and incentive fees are charged at the Partnership level. All clearing fees are borne by the Fund and allocated to the Fund’s limited partners including the Partnership. Professional fees are borne by the Fund and allocated to the Partnership, and also charged directly at the Partnership level. Expenses to investors as a result of the investment in the Fund are approximately the same as they would be if the Partnership traded directly and redemption rights are not affected.

Financial Instrument Risks

Financial Instrument Risks	7. Financial Instrument Risks: In the normal course of business, the Partnership, indirectly through its investment in the Fund, is party to financial instruments with off-balance over-the-counter Futures Contracts. Forward Foreign Currency Contract London Metals Exchange Forward Contracts. Market risk is the potential for changes in the value of the financial instruments traded by the Fund 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 Partnership/Fund are exposed to a market risk equal to the value of the futures and forward contracts held and unlimited liability on such contracts sold short. Credit risk is the possibility that a loss may occur due to the failure of a counterparty to perform according to the terms of a contract. The Partnership’s/Fund’s risk of loss in the event of a counterparty default is typically limited to the amounts recognized in the Statements of Financial Condition and is not represented by the contract or notional amounts of the instruments. The Partnership’s/Fund’s risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership/Fund to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership/Fund have credit risk and concentration risk, as MS&Co., an MS&Co. affiliate or JPMorgan are counterparties or brokers with respect to the Partnership’s/Fund’s assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through MS&Co. or an MS&Co. affiliate, the Partnership’s/Fund’s counterparty is an exchange or clearing organization. The General Partner monitors and attempts to mitigate the Partnership’s/Fund’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 Partnership/Fund may be subject. These monitoring systems generally allow the General Partner to statistically analyze actual trading results with risk-adjusted The majority of these financial instruments mature within one year of the inception date. However, due to the nature of the Fund’s business, these instruments may not be held to maturity. The risk to the limited partners that have purchased Redeemable Units is limited to the amount of their share of the Partnership’s net assets and undistributed profits. This limited liability is a result of the organization of the Partnership as a limited partnership under New York law. In the ordinary course of business, the Fund enters into contracts and agreements that contain various representations and warranties and which provide general indemnifications. The Fund’s maximum exposure under these arrangements cannot be determined, as this could include future claims that have not yet been made against the Fund. The Fund considers the risk of any future obligation relating to these indemnifications to be remote.
