1.	Organization:

Ceres Tactical Commodity L.P. (formerly, Managed Futures Premier Aventis II L.P.) (the “Partnership”) is a limited partnership organized on April 20, 2005 under the partnership laws of the State of New York to engage, directly or indirectly, in the speculative trading of commodity interests on U.S. and international futures, options on futures and forward markets. The Partnership may also engage, directly or indirectly, in swap transactions and other derivative transactions with the approval of the General Partner (as defined below). Initially, the Partnership’s investment strategy focused on energy and energy-related investments. While the Partnership is expected to continue to have significant exposure to energy and energy-related markets, such trading will no longer be the Partnership’s primary focus. Therefore, the Partnership’s past trading performance will not necessarily be indicative of future results. The sectors traded include energy, grains, livestock, metals and softs. The commodity interests that are traded by the Partnership directly or indirectly through its investment in the Funds (as defined below) are volatile and involve a high degree of market risk. The General Partner may also determine to invest up to all of the Partnership’s assets (directly or indirectly through its investment in the Funds) in United States (“U.S.”) Treasury bills and/or money market mutual funds, including money market mutual funds managed by Morgan Stanley or its affiliates. During the initial offering period, the Partnership sold 11,925 redeemable units of limited partnership interest (“Redeemable Units”). The Partnership commenced trading on September 6, 2005. The Partnership privately and continuously offers Redeemable Units to qualified investors. There is no maximum number of Redeemable Units that may be sold by the Partnership.

Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the “General Partner”) and commodity pool operator of the Partnership and is the trading manager (the “Trading Manager”) of Harbour Square Master (as defined below). As of January 1, 2017, the General Partner became a wholly-owned subsidiary of Morgan Stanley Domestic Holdings, Inc. (“MSD Holdings”). MSD Holdings is ultimately owned by Morgan Stanley. Morgan Stanley is a publicly held company whose shares are listed on the New York Stock Exchange. Morgan Stanley is engaged in various financial services and other businesses. Prior to January 1, 2017, the General Partner was a wholly-owned subsidiary of Morgan Stanley Smith Barney Holdings LLC.

As of December 31, 2018, all trading decisions are made for the Partnership by Millburn Ridgefield Corporation (“Millburn”), Ospraie Management, LLC (“Ospraie”), Aquantum GmbH (“Aquantum”) and Harbour Square Capital Management LLC (“Harbour Square”) (each, an “Advisor” and, collectively, the “Advisors”), each, a registered commodity trading advisor. Effective November 30, 2018, Aventis Asset Management, LLC (“Aventis”) ceased to act as a commodity trading advisor to the Partnership. Each Advisor is allocated a portion of the Partnership’s assets to manage. The Partnership invests the portion of its assets allocated to each of the Advisors either directly, through individually managed accounts, or indirectly through its investment in the Funds. References herein to the “Advisors” may also include, as relevant, Aventis.

During the periods covered by this report, the Partnership’s/Funds’ commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”), a registered futures commission merchant. The Partnership/Funds deposited a portion of their cash in non-trading bank accounts at JPMorgan Chase Bank, N.A.

CMF Harbour Square Master Fund LLC (“Harbour Square Master”), the Partnership and prior to the Partnership’s full redemption on November 30, 2018, MB Master Fund L.P. (“MB Master”), have entered into futures brokerage account agreements with MS&Co. Harbour Square Master is referred to as the “Fund”. Reference herein to the “Funds” may include MB Master.

As of June 13, 2018, the Partnership began offering three classes of limited partnership interests, Class A Redeemable Units, Class D Redeemable Units and Class Z Redeemable Units. All Redeemable Units issued prior to October 31, 2016 were deemed “Class A Redeemable Units.” Class Z Redeemable Units were first issued on January 1, 2017. The rights, liabilities, risks and fees associated with investment in the Class A Redeemable Units were not changed. Class D Redeemable Units were first issued July 1, 2018. The rights, liabilities, risks, and fees associated with investment in the Class A Redeemable Units and Class Z Redeemable Units were not changed. Class A Redeemable Units, Class D Redeemable Units and Class Z Redeemable Units will each be referred to as a “Class” and collectively referred to as the “Classes.” Class A Redeemable Units and Class D Redeemable Units are available to taxable U.S. individuals and institutions, U.S. tax exempt individuals and institutions and non-U.S. investors. Class Z Redeemable Units are offered to limited partners who receive advisory services from Morgan Stanley Smith Barney LLC (doing business as Morgan Stanley Wealth Management) (“Morgan Stanley Wealth Management”) and may also be offered to certain employees of Morgan Stanley and/or its subsidiaries (and their family members). Class A Redeemable Units, Class D Redeemable Units and Class Z Redeemable Units are identical, except that Class A Redeemable Units are subject to a monthly ongoing selling agent fee equal to 1/12 of 2.00% (a 2.00% annual rate) of the net assets of Class A as of the end of each month, which differs from the Class D monthly ongoing selling agent fee of 1/12 of 0.75% (a 0.75% annual rate) of the net assets of Class D as of the end of each month. Class Z Redeemable Units are not subject to a monthly ongoing selling agent fee.

Millburn, Ospraie and Aquantum directly trade the Partnership’s assets allocated to each Advisor through managed accounts in the name of the Partnership pursuant to Millburn’s Commodity Program, Ospraie’s Commodity Program and Aquantum’s Commodity Spread Program, respectively.

The Partnership will be liquidated upon the first to occur of the following: December 31, 2055; the net asset value per Redeemable Unit decreases to less than $400 as of a close of any business day; or under certain other circumstances as set forth in the limited partnership agreement of the Partnership (the “Limited Partnership Agreement”). In addition, the General Partner may, in its sole discretion, cause the Partnership to dissolve if the Partnership’s aggregate net assets decline to less than $1,000,000.

In July 2015, the General Partner delegated certain administrative functions to SS&C Technologies, Inc., a Delaware corporation, currently doing business as SS&C GlobeOp (the “Administrator”). Pursuant to a master services agreement, the Administrator furnishes certain administrative, accounting, regulatory reporting, tax and other services as agreed from time to time. In addition, the Administrator maintains certain books and records of the Partnership. The cost of retaining the Administrator is allocated among the pools operated by the General Partner, including the Partnership.
