Financial Instrument Risks	7. Financial Instrument Risks: I off-balance-sheet over-the-counter Futures Contracts. Forward Foreign Currency Contracts. London Metal Exchange Forward Contracts. Market risk is the potential for changes in the value of the financial instruments traded by the Partnership/Funds 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 is, and the Funds were, exposed to 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/Funds’ risk of loss in the event of counterparty default is (or was with respect to the Funds) typically limited to the amounts recognized in the Statements of Financial Condition and is (was) not represented by the contract or notional amounts of the instruments. The Partnership’s/Funds’ risk of loss is (or was with respect to the Funds) reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership, and permitted the Funds, to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership has, and the Funds had, credit risk and concentration risk, as MS&Co. or an MS&Co. affiliate are (or were with respect to the Funds) counterparties or brokers with respect to the Partnership’s/Funds’ assets. Credit risk with respect to exchange-traded instruments is (or was with respect to the Funds) reduced to the extent that, through MS&Co. or an MS&Co. affiliate, the Partnership’s/Funds’ counterparty is or was an exchange or clearing organization. The General Partner/Trading Manager monitors and attempts (or with respect to the Funds, monitored and attempted) to mitigate the Partnership’s/Funds’ risk exposure on a daily basis through financial, credit and risk management monitoring systems, and accordingly, believes (or with respect to the Funds, believed) that it has or had effective procedures for evaluating and limiting the credit and market risks to which the Partnership/Funds may or may have been subject. These monitoring systems generally allow the General Partner/Trading Manager to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures, exchange-cleared swaps, forward and option contracts by sector, margin requirements, gain and loss transactions and collateral positions. The majority of these financial instruments mature within one year 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 Partnership/Funds enter (or with respect to the Funds, entered) into contracts and agreements that contain various representations and warranties and which provide or provided general indemnifications. The Partnership’s/Funds’ maximum exposure under these arrangements cannot be determined, as this could include future claims that have not yet been made against the Partnership/Funds. The General Partner/Trading Manager consider the risk of any future obligation relating to these indemnifications to be remote. Since its discovery in December 2019, a new strain of coronavirus, which causes the viral disease known as COVID-19, The outbreak of the novel coronavirus in many countries is having and will likely continue to have an adverse impact on global commercial activity, which has contributed to significant volatility in financial markets. The global impact of the outbreak has been rapidly evolving, and as cases of the virus have been identified in additional countries, many countries have reacted by instituting quarantines and restrictions on travel. These actions are creating disruption in supply chains, and adversely impacting a number of industries, including but not limited to transportation, hospitality, and entertainment. The impact of COVID-19 The rapid development of this situation precludes any prediction as to the ultimate adverse impact of the novel coronavirus. Nevertheless, the novel coronavirus presents (or presented with respect to the Funds) material uncertainty and risk with respect to the Partnership’s/Funds’ investments and operations.
