What is UNG?
The United States Natural Gas Fund, LP (“UNG”) is a Delaware limited partnership organized on September 11, 2006. UNG maintains its main business office at 1850 Mt. Diablo Boulevard, Suite 640, Walnut Creek, California 94596. UNG is a commodity pool that issues limited partnership interests (“shares”) traded on the NYSE Arca, Inc. (the “NYSE Arca”). UNG’s shares began trading on April 18, 2007. It operates pursuant to the terms of the Fifth Amended and Restated Agreement of Limited Partnership dated as of December 15, 2017 (as amended from time to time, the “LP Agreement”), which grants full management control to its general partner, United States Commodity Funds LLC (“USCF”).
The investment objective of UNG is for the daily changes in percentage terms of its per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the price of natural gas delivered at the Henry Hub, Louisiana, as measured by the daily changes in the price of a specified short-term futures contract called the “Benchmark Futures Contract”, plus interest earned on UNG’s collateral holdings, less UNG’s expenses. The Benchmark Futures Contract is the futures contract on natural gas as 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 the futures contract that is the next month contract to expire.

UNG seeks to achieve its investment objective by investing so that the average daily percentage change in UNG’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Futures Contract over the same period. Additionally, by investing primarily in futures contracts for natural gas that are traded on the NYMEX, ICE Futures Europe and ICE Futures U.S. (together, “ICE Futures”) or other U.S. and foreign exchanges (collectively, “Futures Contracts”), and to a lesser extent, in order to comply with regulatory requirements, risk mitigation measures, (including those that may be taken by UNG, UNG’s futures commission merchants (“FCMs”), counterparties or other market participants), liquidity requirements, or in view of market conditions, other natural gas-related investments such as cash settled options on Futures Contracts, forward contracts for natural gas, cleared swap contracts, and non-exchange traded (“over-the- counter” or “OTC”) transactions that are based on the price of natural gas, crude oil and other petroleum-based fuels, as well as futures contracts for crude oil, heating oil, gasoline, and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Natural Gas-Related Investments”). Market conditions that USCF currently anticipates could cause UNG to invest in Other Natural Gas-Related Investments include, but are not limited to, those allowing UNG to obtain greater liquidity or to execute transactions with more favorable pricing. For convenience and unless otherwise specified, Futures Contracts and Other Natural Gas-Related Investments collectively are referred to as “Natural Gas Interests” in this annual report on Form 10-K.
In addition, USCF believes that market arbitrage opportunities cause daily changes in UNG’s share price on the NYSE Arca on a percentage basis to closely track daily changes in UNG’s per share NAV on a percentage basis. USCF further believes that the daily changes in prices of the Benchmark Futures Contract have historically tracked the daily changes in the spot price of natural gas. USCF believes that the net effect of these relationships will be the daily changes in the price of UNG’s shares on NYSE Arca on a percentage basis will closely track the daily changes in the spot price of natural gas on a percentage basis, plus interest earned on UNG’s collateral holdings, less UNG’s expenses. Investors should be aware that UNG’s investment objective is not for its NAV or market price of shares to equal, in dollar terms, the spot price of natural gas or any particular futures contract based on natural gas, nor is UNG’s investment objective for the percentage change in its NAV to reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. This is because natural market forces called contango and backwardation may impact and have impacted the total return on an investment in UNG’s shares during the past year relative to a hypothetical direct investment in natural gas and, in the future, it is likely that the relationship between the market price of UNG’s shares and the changes in the spot prices of natural gas will continue to be impacted by contango and backwardation. (It is important to note that the disclosure above ignores the potential costs associated with physically owning and storing natural gas, which could be substantial.)

How Does UNG Operate?
An investment in UNG’s shares provides a means for diversifying an investor’s portfolio or hedging exposure to changes in natural gas prices. An investment in the shares allows both retail and institutional investors to easily gain this exposure to the natural gas market in a transparent, cost-effective manner.
The net assets of UNG consist primarily of investments in futures contracts for natural gas, crude oil, diesel-heating oil, gasoline, and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Futures Contracts”) and, to a lesser extent, in order to comply with regulatory requirements, risk mitigation measures (including those that may be taken by UNG, UNG’s FCMs, counterparties or other market participants), liquidity requirements, or in view of market conditions, other natural gas-related investments such as cash-settled options on Futures Contracts, forward contracts for natural gas, cleared swap contracts and non-exchange traded over-the-counter (“OTC”) transactions that are based on the price of natural gas, oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Natural Gas-Related Investments”).
Market conditions that USCF currently anticipates could cause UNG to invest in Other Natural Gas- Related Investments include, but are not limited to, those allowing UNG to obtain greater liquidity or to execute transactions with more favorable pricing. For convenience and unless otherwise specified, Futures Contracts and Other Natural Gas-Related Investments collectively are referred to as “Natural Gas Interests” in this annual report on Form 10-K. UNG invests substantially the entire amount of its assets in Futures Contracts while supporting such investments by holding the amounts of its margin, collateral and other requirements relating to these obligations in short-term obligations of the United States of two years or less (“Treasuries”), cash and cash equivalents. The daily holdings of UNG are available on UNG’s website at www.uscfinvestments.com.
USCF employs a “neutral” investment strategy in order to track changes in the price of the Benchmark Futures Contract regardless of whether the price goes up or goes down. UNG’s “neutral” investment strategy is designed to permit investors generally to purchase and sell UNG’s shares for the purpose of investing indirectly in natural gas in a cost-effective manner, and/or to permit participants in the natural gas or other industries to hedge the risk of losses in their natural gas-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with investing in natural gas and/or the risks involved in hedging may exist. In addition, an investment in UNG involves the risk that the daily changes in the price of UNG’s shares, in percentage terms, will not accurately track the daily changes in the Benchmark Futures Contract, in percentage terms, and that daily changes in the Benchmark Futures Contract, in percentage terms, will not closely correlate with daily changes in the spot prices of natural gas, in percentage terms.
The Benchmark Futures Contract is changed from the near month contract to the next month contract over a four-day period. Each month, the Benchmark Futures Contract changes starting at the end of the day on the date two weeks prior to expiration of the near month contract for that month. During the first three days of the period, the applicable value of the Benchmark Futures Contract is based on a combination of the near month contract and the next month contract as follows: (1) day 1 consists of 75% of the then near month contract’s price plus 25% of the price of the next month contract, divided by 75% of the near month contract’s prior day’s price plus 25% of the price of the next month contract, (2) day 2 consists of 50% of the then near month contract’s price plus 50% of the price of the next month contract, divided by 50% of the near month contract’s prior day’s price plus 50% of the price of the next month contract, and (3) day 3 consists of 25% of the then near month contract’s price plus 75% of the price of the next month contract, divided by 25% of the near month contract’s prior day’s price plus 75% of the price of the next month contract. On day 4, the Benchmark Futures

Contract is the next month contract to expire at that time and that contract remains the Benchmark Futures Contract until the beginning of the following month’s change in the Benchmark Futures Contract over a four-day period.
On each day during the four-day period, USCF anticipates it will “roll” UNG’s positions in Natural Gas Interests by closing, or selling, a percentage of UNG’s positions in Natural Gas Interests and reinvesting the proceeds from closing those positions in new Natural Gas Interests that reflect the change in the Benchmark Futures Contract.
The anticipated dates that the monthly four-day roll period will commence are posted on UNG’s website at www.uscfinvestments.com, and are subject to change without notice.
UNG’s total portfolio composition is disclosed on its website each business day that the NYSE Arca is open for trading. The website disclosure of portfolio holdings is made daily and includes, as applicable, the name and value of each Natural Gas Interest, the specific types of Other Natural Gas-Related Investments and characteristics of such Other Natural Gas-Related Investments, the name and value of each Treasury and cash equivalent, and the amount of cash held in UNG’s portfolio. UNG’s website is publicly accessible at no charge. UNG’s assets used for margin and collateral are held in segregated accounts pursuant to the Commodity Exchange Act (the “CEA”) and CFTC regulations.
The shares issued by UNG may only be purchased by Authorized Participants and only in blocks of 100,000 shares, called “Creation Baskets.” The amount of the purchase payment for a Creation Basket is equal to the aggregate NAV of the shares in the Creation Basket. Similarly, only Authorized Participants may redeem shares and only in blocks of 100,000 shares, called “Redemption Baskets.” The amount of the redemption proceeds for a Redemption Basket is equal to the aggregate NAV of shares in the Redemption Basket. The purchase price for Creation Baskets and the redemption price for Redemption Baskets are the actual per share NAV calculated at the end of the business day when a request for a purchase or redemption is received by UNG. The NYSE Arca publishes an approximate per share NAV intra-day based on the prior day’s per share NAV and the current price of the Benchmark Futures Contract, but the price of Creation Baskets and Redemption Baskets is determined based on the actual per share NAV calculated at the end of the day.
While UNG issues shares only in Creation Baskets, shares are listed on the NYSE Arca and investors may purchase and sell shares at market prices like any listed security.
What is UNG’s Investment Strategy?
In managing UNG’s assets, USCF does not use a technical trading system that issues buy and sell orders. USCF instead employs a quantitative methodology whereby each time a Creation Basket is sold, USCF purchases Natural Gas Interests, such as the Benchmark Futures Contract and Other Natural Gas – Related Investments, that have an aggregate market value that approximates the amount of Treasuries and/or cash received upon the issuance of the Creation Basket.
UNG intends to continue to pursue its investment objective as described above. By remaining invested as fully as possible in Futures Contracts or Other Natural Gas-Related Investments, USCF believes that the daily changes in percentage terms of UNG’s NAV will continue to closely track the daily changes in percentage terms in the price of the Benchmark Futures Contract. USCF believes that certain arbitrage opportunities result in the price of the shares traded on the NYSE Arca closely tracking the per share NAV of UNG. Additionally, Futures Contracts as traded on the NYMEX have closely tracked the spot price of natural gas. Based on these expected interrelationships, USCF believes that the daily changes in the price of UNG’s shares as traded on the NYSE Arca, on a percentage basis, have closely tracked and will continue to closely track the changes in the spot price of natural gas, on a percentage basis. For performance data relating to UNG’s ability to track its benchmark, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Tracking UNG’s Benchmark” in this annual report on Form 10-K.
USCF endeavors to place UNG’s trades in Natural Gas Interests and otherwise manage UNG’s investments so that “A” will be within plus/minus ten percent (10%) of “B,” where:
●A is the average daily percentage change in UNG’s per share NAV for any period of 30 successive valuation days; i.e., any NYSE Arca trading day as of which UNG calculates its per share NAV; and
●B is the average daily percentage change in the price of the Benchmark Futures Contract over the same period.

USCF further believes that the daily changes in UNG’s NAV in percentage terms will closely track the daily changes in percentage terms of the Benchmark Futures Contract, less UNG’s expenses.

Management’s Discussion and Analysis of Financial Condition and Results of Operations – Tracking UNG’s Benchmark” in this annual report on Form 10-K.
UNG’s purchase of Futures Contracts other than the Benchmark Futures Contract and/or Other Natural Gas-Related Investments, if any, depends on various factors, including diversification of UNG’s investments in futures contracts with respect to the month of expiration and the prevailing price volatility of particular contracts. While USCF has made significant investments in NYMEX Futures Contracts, for various reasons, including the ability to enter into the precise amount of exposure to the natural gas market, position limits or other regulatory requirements limiting UNG’s holdings, and market conditions, it may invest in Futures Contracts traded on other exchanges and invest in Other Natural Gas-Related Investments. To the extent that UNG invests in Other Natural Gas-Related Investments, it prioritizes investments in contracts and instruments that are economically equivalent to the Benchmark Futures Contract, including cleared swaps that satisfy such criteria, and then, to a lesser extent, it may invest in other types of cleared swaps and other contracts, instruments and non-cleared swaps, such as swaps in the over-the-counter market (or commonly referred to as the “OTC market”). If UNG is required by law or regulation, or by one of its regulators, including a futures exchange, to reduce its position in the Benchmark Futures Contract to the applicable position limit or to a specified accountability level or if market conditions dictate it would be more appropriate to invest in Other Natural Gas-Related Investments, a substantial portion of UNG’s assets could be invested in accordance with such priority in Other Natural Gas-Related Investments that are intended to replicate the return on the Benchmark Futures Contract. As UNG’s assets reach higher levels, it is more likely to exceed position limits, accountability levels or other regulatory limits and, as a result, it is more likely that it will invest in accordance with such priority in Other Natural Gas-Related Investments at such higher levels. In addition, market conditions that USCF currently anticipates could cause UNG to invest in Other Natural Gas-Related Investments include those allowing UNG to obtain greater liquidity or to execute transactions with more favorable pricing. See “Risk Factors Involved with an Investment in UGA” for a discussion of the potential impact of regulation on UNG’s ability to invest in OTC transactions and cleared swaps.
What is the Natural Gas Market and the Petroleum-Based Fuel Market?
Natural Gas. Natural gas accounts for almost a quarter of U.S. energy consumption. The price of natural gas is established by the supply and demand conditions in the North American market, and more particularly, in the main refining center of the U.S. Gulf Coast. The natural gas market essentially constitutes an auction, where the highest bidder wins the supply. When markets are “strong” (i.e., when demand is high and/or supply is low), the bidder must be willing to pay a higher premium to capture the supply. When markets are “weak” (i.e., when demand is low and/or supply is high), a bidder may choose not to outbid competitors, waiting instead for later, possibly lower priced, supplies. Demand for natural gas by consumers, as well as agricultural, manufacturing and transportation industries, determines overall demand for natural gas. Since the precursors of product demand are linked to economic activity, natural gas demand will tend to reflect economic conditions. However, other factors such as weather significantly influence natural gas demand.
The NYMEX is the world’s largest physical commodity futures exchange and the dominant market for the trading of energy and precious metals. The Benchmark Futures Contract trades in units of 10,000 MMBtu and is based on delivery at the Henry Hub in Louisiana, the nexus of 16 intra- and interstate natural gas pipeline systems that draw supplies from the region’s prolific gas deposits. The pipelines serve markets throughout the U.S. East Coast, the Gulf Coast, the Midwest, and up to the Canadian border. Because of the volatility of natural gas prices, a vigorous basis market has developed in the pricing relationships between the Henry Hub and other important natural gas market centers in the continental United States and Canada. The NYMEX makes available for trading a series of basis swap futures contracts that are quoted as price differentials between approximately 30 natural gas pricing points and the Henry Hub. The basis contracts trade in units of 2,500 MMBtu on the New York Mercantile Exchange ClearPort® trading platform. The New York Mercantile Exchange ClearPort® is an electronic trading platform through which a slate of energy futures contracts are available for competitive trading. Transactions can also be consummated off-NYMEX and submitted to the NYMEX for clearing via the NYMEX ClearPort® clearing website as an exchange of futures for physicals or an exchange of futures for swaps transactions.
Light, Sweet Crude Oil. Light, sweet crudes are preferred by refiners because of their low sulfur content and relatively high yields of high-value products such as gasoline, diesel fuel, diesel-heating oil, and jet fuel. The price of light, sweet crude oil has historically exhibited periods of significant volatility.

Demand for petroleum products by consumers, as well as agricultural, manufacturing and transportation industries, determines demand for crude oil by refiners. Since the precursors of product demand are linked to economic activity, crude oil demand will tend to reflect economic conditions. However, other factors such as weather also influence product and crude oil demand.
Crude oil supply is determined by both economic and political factors. Oil prices (along with drilling costs, availability of attractive prospects for drilling, taxes and technology, among other factors) determine exploration and development spending, which influence output capacity with a lag. In the short run, production decisions by the Organization of Petroleum Exporting Countries (“OPEC”) also affect supply and prices. Oil export embargoes and the current conflicts in the Middle East represent other routes through which political developments move the market. It is not possible to predict the aggregate effect of all or any combination of these factors.
Diesel-Heating Oil. Diesel-heating oil, also known as No. 2 fuel oil, accounts for 25% of the yield of a barrel of crude oil, the second largest “cut” from oil after gasoline. The diesel-heating oil futures contract listed and traded on the NYMEX trades in units of 42,000 gallons (1,000 barrels) and is based on delivery in the New York harbor, the principal cash market center. The ICE Futures also offers a diesel-heating oil futures contract which trades in units of 42,000 U.S. gallons (1,000 barrels). The diesel-heating oil futures contract is cash-settled against the prevailing market price for diesel-heating oil delivered to the New York Harbor.
Gasoline. Gasoline is the largest single volume refined product sold in the U.S. and accounts for almost half of national oil consumption. The gasoline futures contract listed and traded on the NYMEX trades in units of 42,000 gallons (1,000 barrels) and is based on delivery at petroleum products terminals in the New York harbor, the major East Coast trading center for imports and domestic shipments from refineries in the New York harbor area or from the Gulf Coast refining centers. The price of gasoline has historically been volatile.
What are Futures Contracts?
Futures contracts are agreements between two parties. One party agrees to buy a commodity such as natural gas from the other party at a later date at a price and quantity agreed upon when the contract is made. Futures Contracts are traded on futures exchanges, including the NYMEX. For example, the Benchmark Futures Contract is traded on the NYMEX in units of 10,000 MMBtu. Futures Contracts traded on the NYMEX are priced by floor brokers and other exchange members both through an “open outcry” of offers to purchase or sell the contracts and through an electronic, screen-based system that determines the price by matching electronically offers to purchase and sell. Additional risks of investing in Futures Contracts are included in “
