ORGANIZATION AND BUSINESS | NOTE 1 — ORGANIZATION AND BUSINESS The United States Short Oil Fund, LP (“DNO”) was organized as a limited partnership under the laws of the state of Delaware on June 30, 2008. DNO is a commodity pool that issued limited partnership shares (“shares”) that were purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). DNO will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Third Amended and Restated Agreement of Limited Partnership dated as of December 15, 2017 (the “LP Agreement”). The investment objective of DNO is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to inversely reflect the daily changes in percentage terms of the spot price of West Texas Intermediate (“WTI”) light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the price of the futures contract for WTI light, sweet crude oil traded on the New York Mercantile Exchange (the “NYMEX”) that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case it will be measured by futures contract that is the next month contract to expire (the “Benchmark Futures Contract”), plus interest earned on the Fund’s collateral holdings, less DNO’s expenses. DNO commenced investment operations on September 24, 2009 and has a fiscal year ending on December 31. USCF is responsible for the management of DNO. USCF is a member of the National Futures Association (the “NFA”) and became registered as a commodity pool operator with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005 and a swaps firm on August 8, 2013. USCF is also the general partner of the United States Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”), the United States Gasoline Fund, LP (“UGA”) and the United States Diesel-Heating Oil Fund, LP (“UHN”), which listed their limited partnership shares on the American Stock Exchange (the “AMEX”) under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 2007, “UGA” on February 26, 2008 and “UHN” on April 9, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USO’s, UNG’s, USL’s, UGA’s and UHN’s shares commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States 12 Month Natural Gas Fund, LP (“UNL”) and the United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. USCF is also the sponsor of the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”), the United States Agriculture Index Fund (“USAG”) and the USCF Canadian Crude Oil Index Fund (“UCCO”), each a series of the United States Commodity Index Funds Trust. USCI, CPER and USAG listed their shares on the NYSE Arca under the ticker symbols “USCI” on August 10, 2010, “CPER” on November 15, 2011 and “USAG” on April 13, 2012, respectively. UCCO is currently in registration and has not commenced operations. In addition, USCF is the sponsor of the USCF Funds Trust, a Delaware statutory trust, and each of its series, the United States 3x Oil Fund (“USOU”) and the United States 3x Short Oil Fund (“USOD”), which commenced operations on July 20, 2017. All funds listed previously, other than UCCO, are referred to collectively herein as the “Related Public Funds.” On August 7, 2018, the board of directors of United States Commodity Funds LLC (“USCF”), the general partner of DNO, determined that DNO could not continue its business and operations in an economically efficient manner due to DNO’s inability to attract sufficient assets, thereby hindering its ability to operate efficiently. On that date, the Board of Directors of USCF also authorized and approved the closing and liquidation of DNO together with a plan of liquidation for DNO. DNO filed a current report on Form 8-K dated August 8, 2018 with the SEC that included, as an exhibit a press release, the DNO plan of liquidation and a copy of the notice of required withdrawal from the limited partnership sent to shareholders. DNO also filed a prospectus supplement with the U.S. Securities and Exchange Commission (the "SEC") dated August 8, 2018 that is available on USCF’s website at www.uscfinvestments.com. On September 6, 2018, DNO began the process of liquidating its portfolio. As of the close of regular trading on the NYSE Arca, Inc. (“NYSE Arca”), on September 6, 2018, DNO ceased accepting orders for Creation Baskets and Redemption Baskets from authorized participants. Trading in the shares of DNO on the NYSE Arca was suspended prior to the open of the market on September 7, 2018. On September 7, 2018, DNO filed a post-effective amendment to the registration statement with the SEC to terminate the offering of registered and unsold shares of DNO. The liquidation date for DNO was September 12, 2018 and the proceeds of the liquidation were sent to all remaining shareholders of DNO on or about September 13, 2018. For U.S. federal income tax purposes, these distributions were treated as liquidating distributions and shareholders recognized gain or loss based on the difference between the amount of cash received as part of the liquidating distribution and their adjusted basis in their shares (taking into account all allocations of income, gain, loss, or deduction for the year of liquidation). Items of income, gain, loss, or deduction recognized as a result of the liquidation of DNO’s portfolio were allocated for U.S. federal tax purposes to the shareholders. Any other items of income, gain, loss, or deduction not attributable to the liquidation of DNO’s portfolio were allocated for U.S. federal income tax purposes in accordance with DNO’s general allocation conventions. For further information concerning the U.S. federal income tax consequences of acquiring, holding, and disposing of shares, please review the section titled “U.S. Federal Income Tax Considerations” in the Prospectus. In addition, shareholders are encouraged to consult their own tax advisors concerning the impact of the liquidation of DNO in light of their own unique circumstances. Notice was given to the limited partners of DNO (as such term is defined under DNO’s respective Third Amended and Restated Agreement of Limited Partnership dated as of December 15, 2017) that effective as of 5:00 p.m. (prevailing Eastern Time) on September 13, 2018, each of the limited partners withdrew entirely from DNO, respectively, without further action. The effect of the withdrawal of all the limited partners of DNO was dissolution of DNO. On August 7, 2018, the Board of Directors of USCF also authorized and approved the closing and liquidation for each of USAG and UHN together with a plan of liquidation for each of USAG and UHN. Each of the United States Commodity Index Funds Trust (“USCIFT”), of which USAG is a series, and UHN filed a current report on Form 8-K dated August 8, 2018 with the SEC (as defined below) that included, as an exhibit, the press release, the applicable plan of liquidation, and, in the case of UHN, a copy of the notice of required withdrawal from the limited partnership sent to shareholders. In addition, each of USAG and UHN filed a prospectus supplement with the SEC dated August 8, 2018. Each of the filings is also available on USCF’s website at www.uscfinvestments.com. The liquidation date for each of USAG and UHN was September 12, 2018 and the proceeds of the liquidation were sent to all remaining shareholders of USAG and UHN, respectively, on or about September 13, 2018, with a subsequent distribution of additional liquidation proceeds sent to UHN shareholders on or about September 18, 2018. Each of USAG and UHN also filed a post-effective amendment to the registration statement with the SEC to terminate the offering of registered and unsold shares of USAG and UHN, respectively, and the NYSE Arca filed Forms 25 to effect the withdrawal of the listings for shares of each of USAG and UHN. DNO issued shares to certain authorized purchasers (“Authorized Participants”) by offering baskets consisting of 50,000 shares (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). The purchase price for a Creation Basket was based upon the NAV of a share calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received. As noted above, as of the filing of this quarterly report on Form 10-Q, DNO is no longer issuing shares. In addition, Authorized Participants paid DNO a $350 fee for each order placed to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”), consisting of 50,000 shares. Shares were purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Shares purchased or sold on a nationally recognized securities exchange were not purchased or sold at the per share NAV of DNO but rather at market prices quoted on such exchange. In September 2009, DNO initially registered 25,000,000 shares on Form S-1 with the U.S. Securities and Exchange Commission (the “SEC”). On September 24, 2009, DNO listed its shares on the NYSE Arca under the ticker symbol “DNO”. On that day, DNO established its initial per share NAV by setting the price at $50 and issued 200,000 shares in exchange for $10,000,000. DNO also commenced investment operations on September 24, 2009, by taking short positions in Futures Contracts traded on the NYMEX based on WTI light, sweet crude oil. As noted above, as of the filing of this quarterly report on Form 10-Q, DNO is no longer issuing shares and terminated the offering of registered and unsold shares.
