This is an additional risk factor which could impact the operations and valuation of the Partnership’s assets after the year end. The Advisor is actively monitoring developments closely. Given the nature of the outbreak and the on-going developments, there is a high degree of uncertainty and it is not possible at this time to predict the extent and nature of the overall future impact on the Partnership. The General Partner and the Advisor have concluded that the developments in the global financial markets after the year end did not provide evidence of conditions that existed at the end of the reporting period and have therefore assessed any impact they had as non-adjusting. |

Fair Value Measurements | 4. FAIR VALUE MEASUREMENTS The Trading Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants at the measurement date under current market conditions. The fair value of the Trading Company’s assets and liabilities which qualify as financial instruments approximates the carrying amounts presented on the statements of financial condition. The inputs used to determine the fair value of the Trading Company’s investments are summarized in the three broad levels listed below: • Level 1 — quoted prices in active markets for identical assets or liabilities • Level 2 — investments with significant market observable inputs • Level 3 — investments with significant unobservable inputs, which may include the Trading Company’s own assumptions in determining the fair value of investments Futures contracts are valued based on end of day quoted prices from the exchange and are categorized as Level 1 investments in the fair value hierarchy. Forward contracts and swap agreements are valued at fair value using independent pricing services, which use market observable inputs in their valuations, and are categorized as Level 2 investments in the fair value hierarchy. As of December 31, 2019 and December 31, 2018, the Trading Company did not have any positions categorized as Level 3 investments in the fair value hierarchy. The following is a summary categorization as of December 31, 2019 and December 31, 2018, of the Trading Company’s investments based on the level of inputs utilized in determining the value of such investments: Fair Value Measurements Investments As of Level 1 Level 2 Level 3 Assets Treasury bills $ 79,543,495 $ - $ 79,543,495 $ - Futures contracts 4,995,338 4,995,338 - - Forward contracts 13,200,938 - 13,200,938 - Swap agreements 34,757,966 - 34,757,966 - Total Assets 132,497,737 4,995,338 127,502,399 - Liabilities Futures contracts (1,827,864 ) (1,827,864 ) - - Forward contracts (15,314,094 ) - (15,314,094 ) - Swap agreements (26,937,452 ) - (26,937,452 ) - Total Liabilities (44,079,410 ) (1,827,864 ) (42,251,546 ) - Net Fair Value $ 88,418,327 $ 3,167,474 $ 85,250,853 $ - Fair Value Measurements Investments As of Level 1 Level 2 Level 3 Assets Treasury bills $ 100,496,680 $ - $ 100,496,680 $ - Futures contracts 7,529,667 7,529,667 - - Forward contracts 8,965,462 - 8,965,462 - Swap agreements 24,142,418 - 24,142,418 - Total Assets 141,134,227 7,529,667 133,604,560 - Liabilities Futures contracts (933,619 ) (933,619 ) - - Forward contracts (7,574,813 ) - (7,574,813 ) - Swap agreements (20,957,201 ) - (20,957,201 ) - Total Liabilities (29,465,633 ) (933,619 ) (28,532,014 ) - Net Fair Value $ 111,668,594 $ 6,596,048 $ 105,072,546 $ - The Trading Company discloses the amounts of transfers and reasons for those transfers between levels of the fair value hierarchy, based on the levels assigned under the hierarchy at the reporting period end.

Derivative Financial Instruments and Concentrations of Credit Risk | 5. DERIVATIVE FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF CREDIT RISK The Trading Company seeks to achieve its investment objective by participation in the AHL Diversified Program directed on behalf of the Trading Company by the Advisor. The AHL Diversified Program is a price trend-following trading system, entirely quantitative in nature, and implements trading positions on the basis of statistical analyses of past price histories. The objective of the AHL Diversified Program is to deliver substantial capital growth for commensurate levels of volatility over the medium term, independent of the movement of the stock and bond markets, through the speculative trading, directly and indirectly, of physical commodities, futures contracts, spot and forward contracts, swaps and options on the foregoing, exchanges of futures for physical transactions and other investments on domestic and international exchanges and markets (including the interbank and over-the-counter All of the strategies and systems of the AHL Diversified Program are designed to target defined volatility levels rather than returns, and the investment process is underpinned by computer-supported analytical instruments and disciplined real-time risk and management information systems. A proprietary risk measurement method similar to the industry standard “value-at-risk” pre-defined parameters. Margin-to-equity Futures contracts, forward contracts and swap agreements are recorded on the trade date. Upon entering into futures contracts, forward contracts and swap agreements, the Trading Company may be required to deposit cash or collateral with the brokers. Gains or losses are realized when contracts are matured or closed. Unrealized gains or losses on open contracts and agreements (the difference between contract trade price and fair value) are reported in the statements of financial condition. Interest rate swaps relate to agreements taken out by the Trading Company with major brokers in which the Trading Company either receives or pays a floating rate of interest in return for paying or receiving, respectively, a fixed rate of interest, on the same notional amount for a specified period of time. In the normal course of business, the payment flows are netted against each other, with the difference being paid by one party to the other. Changes in the value of the interest rate swap agreements and amounts received or paid in connection with those changes, are recognized as realized trading gains (losses) on closed contracts/agreements in the statements of operations. The risks related to trading in interest rate swaps include changes in market value and the possible inability of the counterparty to fulfill its obligations under the agreement. The Trading Company may enter into short sales. In order to facilitate a short sale, the Trading Company borrows the applicable financial instrument from a broker or counterparty and delivers it to a buyer. A short sale by the Trading Company creates an obligation on the part of the Trading Company to thereafter purchase the financial instrument in the market at the prevailing market price and deliver it to the broker or counterparty from which it was borrowed. The Trading Company is exposed to the risk of loss to the extent that the price of a financial instrument sold short by the Trading Company increases from the time the Trading Company borrows the financial instrument to the time the Trading Company purchases it in the market to satisfy the Trading Company’s delivery obligation. Consequently, the ultimate cost to the Trading Company to acquire a financial instrument sold short may exceed the amount recognized in financial statements. The Trading Company may enter into credit default swap agreements to provide a measure of protection against the default of an issuer (as buyer of protection) and/or gain credit exposure to an issuer to which it is not otherwise exposed (as seller of protection). Credit default swaps are agreements in which one party pays fixed periodic payments to a counterparty in consideration for a guarantee from the counterparty to make a specific payment should a negative credit event take place (e.g. default, bankruptcy, debt restructuring, etc.). The Trading Company may either buy or sell (write) credit default swaps. As a buyer, upon the occurrence of a specified negative credit event, the Trading Company will either receive from the seller an amount equal to the notional amount of the swap and deliver the referenced security or underlying securities comprising an index or receive a net settlement of cash equal to the notional amount of the swap less the agreed upon recovery value of the security or underlying securities comprising an index. As a seller (writer), upon the occurrence of a specified negative credit event, the Trading Company will either pay the buyer an amount equal to the notional amount of the swap and take delivery of the referenced security or underlying securities comprising an index or pay a net settlement of cash equal to the notional amount of the swap less the agreed upon recovery value of the security or underlying securities comprising an index. In the event of default by the counterparty, the Trading Company may recover amounts paid under the agreement either partially or in total by offsetting any payables and/or receivables with collateral held or pledged. The counterparty risk for centrally-cleared credit default swap agreements is generally lower than for credit default swap agreements not centrally-cleared. However, there can be no assurance that the clearing organization, or its members, will satisfy its obligations to the Trading Company. These periodic payments received or made under swap agreements by the Trading Company are included in net realized trading gains (losses) on closed contracts/agreements in the statements of operations. When the swap is terminated, the Trading Company will record a realized gain (loss) equal to the difference between the proceeds from (or cost of) closing the transaction and the Trading Company’s basis in the contract, if any. Swap transactions involve, to varying degrees, elements of credit and market risk in excess of the amounts recognized on the statements of financial condition. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty or the clearing organization to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions. As of December 31, 2019 and December 31, 2018, the total fair value and notional amounts of credit default swaps on indices where the Trading Company is the seller is presented in the following table by contract terms: Fair Value and Notional Amounts by Contract Term December 31, 2019 December 31, 2018 1-5 1-5 Credit spread (in basis points) Fair Value Notional Fair Notional 0-100 $ 641,489 $ 175,000,000 $ - $ - 101-250 237,204 20,000,000 - - 251-350 1,622,236 15,000,000 - - 351-450 - - - - 450+ - - - - Total $ 2,500,929 $ 210,000,000 $ - $ - The notional amount represents the maximum potential pay out that the Trading Company could be required to make if a credit event were to occur under each agreement. The maximum payout amount may be offset by the subsequent sale, if any, of assets obtained via the execution of a payout event, upfront fees received upon entering into the contracts, or net amounts received from the settlement of offsetting purchased protection in credit default swap contracts entered into by the Trading Company for the same reference entity or entities. As of December 31, 2019 and December 31, 2018, all credit default swap contracts entered into by the Trading Company are on indices. The credit spread of the underlying indices, derived from the fair value at December 31, 2019 of each credit default swap where the Trading Company is a seller, ranged between 44 basis points and 281 basis points. As of December 31, 2018, the Trading Company did not hold any credit default swaps where the Trading Company is a seller. The credit spread is generally indicative of the status of the underlying risk of default by the applicable reference entity or index and is likely to be different than the contractual spread on the credit default swap. Higher credit spreads are indicative of a higher likelihood of non-performance by the Trading Company. As of December 31, 2019 the Trading Company posted cash collateral of $3,044,358, and as of December 31, 2018, the Trading Company posted cash collateral of $8,478,832, with respective counterparties on these agreements in the normal course of business. As of December 31, 2019, all open credit default swap agreements on selling protection have a maturity date of December 20, 2024. As of December 31, 2018, there were no open credit default swap agreements on selling protection. During the year ended December 31, 2019, the Trading Company traded 95,902 exchange-traded futures contracts and settled 233,718 forward contracts and 1,026 swap agreements. During the year ended December 31, 2018, the Trading Company traded 144,330 exchange-traded futures contracts and settled 224,024 forward contracts and 2,339 swap agreements. As of December 31, 2019, the gross notional value of open forward contracts is $2,674,274,863 and the gross notional value of open swap contracts is $243,523,554. As of December 31, 2018, the gross notional value of open forward contracts is $1,794,976,730 (in the prior year financial statements this figure was presented in local currency and amounted to 110,610,989,818) and the gross notional value of open swap contracts is $202,675,262. The trading activity of open forward and swap contracts as of December 31, 2019 and 2018 is indicative of the trading activity throughout the year. The Trading Company trades derivative financial instruments that involve varying degrees of market and credit risk. Market risks may arise from unfavorable changes in interest rates, foreign exchange rates, or the fair values of the instruments underlying the contracts. All contracts are stated at fair value, and changes in those values are reflected in the net change in unrealized trading gains (losses) on open contracts/agreements in the statements of operations. Credit risk arises from the potential inability of counterparties to perform in accordance with the terms of a contract. The credit risk for OTC derivative contracts is limited to the net unrealized gain plus any collateral posted net of unrealized losses or upfront fees posted, if any, for each counterparty for which a netting agreement exists and is included in the statements of financial condition. Upfront fees are listed on the statements of financial condition as net premiums paid/received on credit default swap agreements and are shown net by counterparty for which a netting agreement exists. Counterparty relationships are governed by various contracts. These contracts can be based on industry standard agreements, such as International Swap and Derivatives Association agreements for OTC contracts. These agreements set forth each party’s basic rights, responsibilities, and duties. These agreements also contain information regarding financial terms and conditions, as well as termination and events of default provisions. Certain agreements contain provisions that require the Trading Company to post additional collateral upon the occurrence of specific credit risk related events or upon notice from the counterparty. As the Trading Company’s trading strategies are dependent upon the existence of these agreements, the Trading Company’s counterparties usually have multiple specified events under which they can terminate individual transactions or the entire agreement. These are most commonly related to declines in assets under management and performance below certain thresholds during a specified period. It is not guaranteed that counterparties will move to terminate individual transactions or entire agreements if a “trigger event” were to occur; however, it is their right to do so, and such a move could severely impact the Trading Company’s portfolio. At December 31, 2019 and December 31, 2018, the OTC contracts subject to such trigger events in a net liability position were the foreign currency forward contracts, interest rate swap agreements and credit default swap agreements. The details of the net liability positions by counterparty are disclosed later in this note on the additional disclosures regarding the offsetting of derivative liabilities table. The ultimate amounts that may be required as payment to settle the derivative instruments in connection with the triggering of such credit contingency features as of December 31, 2019 and December 31, 2018, may differ from the net liability amounts recorded as of December 31, 2019 and December 31, 2018, and such differences can be material. For exchange-traded futures contracts, the clearing organization functions as the central counterparty for each transaction and, therefore, bears the risk of settlement to and from counterparties, which mitigates the credit risk of these instruments. As of December 31, 2019 and December 31, 2018, all credit default swaps held by the Trading Company are centrally cleared swaps.

The party that has the larger payable pays the excess of the larger amount over the smaller amount to the other party. The netting agreements do not apply to amounts owed to or from different counterparties.
