Nature of Business and Significant Accounting Policies
Accounting Principles	Accounting Principles: Pursuant to rules and regulations of the SEC, consolidated financial statements of the Partnership are prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). The Partnership is an investment company and follows accounting and reporting guidance under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies.
Consolidation	Consolidation: The Partnership is the sole member of each of the Trading Companies. The Trading Companies, in turn, are the only members of GP Cash Management. The Partnership presents consolidated financial statements, which include the accounts of the Trading Companies and GP Cash Management. All material inter-company accounts and transactions are eliminated in consolidation.
Use of estimates	Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Cash and cash equivalents	Cash and cash equivalents: Cash and cash equivalents may include cash, overnight investments, commercial paper, U.S. treasury bills, money market funds and short-term investments in interest-bearing demand deposits with banks and cash managers with original maturities of three months or less at the date of acquisition.
Valuation of investments	Valuation of investments: All investments are used for trading purposes and recorded at their estimated fair value, as described in Note 2. Substantially all of the Partnership’s assets and liabilities are considered financial instruments and are recorded at fair value or at carrying amounts that approximate fair value because of the short maturity of the instruments.
Investment transactions, investment income and expenses	Investment transactions, investment income and expenses: Futures contracts, forward contracts and options on futures and forward contracts and securities are recorded on a trade date basis and realized gains or losses are recognized when contracts/positions are liquidated. Unrealized gains or losses on open contracts/positions (the difference between contract trade price and market price) or securities are reported in the consolidated statement of financial condition as a net unrealized gain or loss, as there exists a right of offset of unrealized gains or losses in accordance with FASB ASC 210-20, Balance Sheet, Offsetting. Any change in net unrealized gain or loss from the preceding period is reported in the consolidated statement of operations. Interest income and expense is recognized under the accrual basis. Set forth in Note 10 are instruments and transactions eligible for offset in the consolidated statement of financial condition and which are subject to derivative clearing agreements with the Partnership’s clearing brokers. Each clearing broker nets margin held on behalf of the Partnership or payment obligations of the clearing broker to the Partnership against any payment obligations of the Partnership to the clearing broker. The Partnership is required to deposit margin at each clearing broker to meet the original and maintenance requirements established by that clearing broker, and/or the exchange or clearinghouse associated with the exchange on which the instrument is traded. The derivative clearing agreements give each clearing broker a security interest in this margin to secure any liabilities owed to the clearing broker arising from a default by the Partnership.
Commissions	Commissions: Commissions and other trading fees are expensed when contracts are opened and closed, and are reflected separately in the consolidated statement of operations.
Redemptions payable	Redemptions payable: Pursuant to the provisions of FASB ASC 480, Distinguishing Liabilities from Equity, redemptions approved by the General Partner prior to month end with a fixed effective date and fixed amount are recorded as redemptions payable as of month end.
Income taxes	Income taxes: No provision for income taxes has been made in these consolidated financial statements as each partner is individually responsible for reporting income or loss based on its respective share of the Partnership’s income and expenses as reported for income tax purposes. The Partnership follows the provisions of ASC 740, Income Taxes. FASB guidance requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Partnership’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained “when challenged” or “when examined” by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense and liability in the current year. If a tax position does not meet the minimum statutory threshold to avoid payment of penalties, an expense for the amount of the statutory penalty and interest, if applicable, shall be recognized in the consolidated statement of operations in the period in which the position is claimed or expected to be claimed. As of September 30, 2017, management has determined that there are no material uncertain income tax positions and, accordingly, has not recorded a liability. The Partnership is generally not subject to examination by U.S. federal or state taxing authorities for tax years before 2013.
Organization and offering costs	Organization and offering costs: All expenses incurred in connection with the organization and the ongoing public offering of partnership interests are paid by the General Partner and are reimbursed to the General Partner by the Partnership. This reimbursement is made monthly. In its discretion, the General Partner may require the Partnership to reimburse the General Partner in any subsequent calendar year for amounts that exceed the limits in Note 5 in any calendar year, provided that the maximum amount reimbursed by the Partnership will not exceed the overall limit. Amounts reimbursed by the Partnership with respect to ongoing public offering expenses are charged to expense from operations at the time of reimbursement or accrual. Any amounts reimbursed by the Partnership with respect to organizational expenses are expensed at the time the reimbursement is incurred or accrued. If the Partnership terminates prior to completion of payment of the calculated amounts to the General Partner, the General Partner will not be entitled to any additional payments, and the Partnership will have no further obligation to the General Partner. At September 30, 2017 and December 31, 2016, unreimbursed organization and offering costs incurred by the General Partner were approximately $245,000 and $91,000, respectively.
Foreign currency transactions	Foreign currency transactions: The Partnership’s functional currency is the U.S. dollar; however, it transacts business in currencies other than the U.S. dollar. Assets and liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect at the date of the consolidated statement of financial condition. Income and expense items denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect during the period. Gains and losses resulting from the translation to U.S. dollars are reported in income currently. The Partnership does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized or unrealized gain or loss from investments.
Swap contracts	Swap contracts: Certain Trading Companies of the Partnership strategically allocate a portion or all of their assets to total return swaps selected at the direction of the General Partner. A swap is a bilaterally negotiated agreement between two parties to exchange cash flows based upon an asset, rate or some other reference index. In a typical swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount” (i.e., the amount or value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a “basket” of commodities or other investments representing a particular index. Changes in the value of the swap agreement are recognized as unrealized gains or losses in the consolidated statement of operations by marking to market on a daily basis to reflect the value of the swap agreement at the end of each day as reported by the swap counterparty. Realized gains and losses from a decrease in the notional value of the swap are recognized on trade date. A liquidation payment received or made at the termination of the swap agreement will first be offset against the swap balance outstanding at the time the position is liquidated, with the remainder being recorded as a realized gain or loss in the consolidated statement of operations. Through its Trading Companies the Partnership has entered into total return swaps with Deutsche Bank AG. The Partnership maintains cash as collateral to secure its obligations under the swaps. As of September 30, 2017 and December 31, 2016, the notional value of the swaps was $60,638,617 and $60,638,617 and the cash margin balance was $13,993,000 and $12,996,500, respectively. The swaps were effective July 1, 2015 and April 5, 2016 and have a term of five years and three years, respectively.
Statement of cash flows	Statement of cash flows: The Partnership has elected not to provide statements of cash flows as permitted by FASB ASC 230, Statement of Cash Flows. The Partnership noted that as of and for the period ended September 30, 2017 and 2016, substantially all investments are carried at fair value and classified as Level 1 and Level 2 measurements, the Partnership carried no debt, and the statements of changes in partners’ capital (net asset value) is presented.
Recent accounting pronouncements	Recent accounting pronouncements: In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements. The amendments in the update represent changes to clarify, correct errors, or make minor improvements to the Accounting Standards Codification. Among the updates is an amendment to Topic 820, Fair Value Measurement, which clarifies the difference between a valuation approach and a valuation technique when applying the guidance in that Topic. The amendment also requires an entity to disclose when there has been a change in either or both a valuation approach and/or a valuation technique. The amended disclosure requirement is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Partnership adopted the amendment in ASU 2019-19 as of January 1, 2017, and the adoption did not have a material impact on the Partnership’s financial statements. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606) – Deferral of Effective Date, which defers the effective date of ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments in ASU 2014-09 affect any entity that enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. In March 2016, April 2016 and May 2016, the FASB issued ASU 2016-08 Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, and ASU 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, respectively. The amendments in these updates affect entities with transactions included within the scope of Topic 606. The scope of that Topic includes entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The guidance is effective for annual reporting periods beginning after December 15, 2017. The Partnership does not expect the adoption of these pronouncements to have an impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01 Financial Instruments – Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Liabilities. The amendments in this update affect all entities that hold financial assets or owe financial liabilities. The guidance will impact the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The guidance is effective for fiscal years beginning after December 15, 2017. The Partnership does not expect the adoption of this pronouncement to have an impact on its consolidated financial statements.
