Item 1.  Business.




What
is US12OF?




The
United States 12 Month Oil Fund, LP (“US12OF”) is a Delaware limited
partnership organized on June 27, 2007. US12OF maintains its main business
office at 1320 Harbor Bay Parkway, Suite 145, Alameda, California 94502. US12OF
is a commodity pool that issues limited partnership interests (“units”) traded
on the NYSE Arca, Inc. (the “NYSE Arca”). It operates pursuant to the terms of
the Amended and Restated Agreement of Limited Partnership dated as of
December 4, 2007 (the “LP Agreement”), as amended from time to time, which
grants full management control to United States Commodity Funds LLC (the
“General Partner”).





The
investment objective of US12OF is for the changes in percentage terms of its
units’ net asset value (“NAV”) to reflect the changes in percentage terms of the
spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured
by the changes in the average of the prices of 12 futures contracts on light,
sweet crude oil traded on the New York Mercantile Exchange (the “NYMEX”)
consisting of the near month contract to expire and the contracts for the
following 11 months for a total of 12 consecutive months’ contracts (the
“Benchmark Futures Contracts”), except when the near month contract is within
two weeks of expiration, in which case it is measured by the futures contracts
that are the next month contract to expire and the contracts for the following
11 consecutive months, less US12OF’s expenses. When calculating the daily
movement of the average price of the 12 contracts, each contract month is
equally weighted. US12OF’s units began trading on December 6, 2007. The
General Partner is the general partner of US12OF and is responsible for the
management of US12OF.





Who
is the General Partner?





The
General Partner is a single member limited liability company that was formed in
the state of Delaware on May 10, 2005. Prior to June 13, 2008, the General
Partner was known as Victoria Bay Asset Management, LLC. It maintains its main
business office at 1320 Harbor Bay Parkway, Suite 145, Alameda, California
94502. The General Partner is a wholly-owned subsidiary of Wainwright Holdings,
Inc., a Delaware corporation (“Wainwright”). Mr. Nicholas Gerber (discussed
below) controls Wainwright by virtue of his ownership of Wainwright’s shares.
Wainwright is a holding company.  Wainwright previously owned an
insurance company organized under Bermuda law, which has been liquidated, and a
registered investment adviser firm named Ameristock Corporation, which has been
distributed to the Wainwright shareholders. The General Partner is a member of
the National Futures Association (the “NFA”) and registered as a commodity pool
operator (“CPO”) with the Commodity Futures Trading Commission (the “CFTC”) on
December 1, 2005.





On May
12, 2005, the General Partner formed the United States Oil Fund, LP
(“USOF”), another limited partnership that is a commodity pool and
issues units traded on the NYSE Arca.  The investment
objective of USOF is for the changes in percentage terms of its units’ NAV to
reflect the changes in percentage terms of the spot price of light, sweet crude
oil delivered to Cushing, Oklahoma, as measured by the changes in the price of
the futures contract for light, sweet crude oil traded on the NYMEX, less USOF’s
expenses. USOF’s units began trading on April 10, 2006.  The
General Partner is the general partner of USOF and is responsible for the
management of USOF.




On
September 11, 2006, the General Partner formed the United States Natural Gas
Fund, LP (“USNG”), another limited partnership that is a commodity pool
and issues units traded on the NYSE Arca. The investment
objective of USNG is for the changes in percentage terms of its units’ NAV to
reflect the changes in percentage terms of the spot price of natural gas
delivered at the Henry Hub, Louisiana, as measured by the changes in the price
of the futures contract on natural gas traded on the NYMEX, less USNG’s
expenses. USNG’s units began trading on April 18, 2007. The General Partner is
the general partner of USNG and is responsible for the management of
USNG.




On April
12, 2007, the General Partner formed the United States Gasoline Fund, LP
(“UGA”), also a limited partnership that is a commodity pool and issues units
traded on the NYSE Arca. The investment objective of UGA is for the changes
in percentage terms of its units’ NAV to reflect the changes in percentage terms
of the spot price of unleaded gasoline delivered to the New York harbor, as
measured by the changes in the price of the futures contract on gasoline traded
on the NYMEX, less UGA’s expenses. UGA’s units began trading on February 26,
2008. The General
Partner is the general partner of UGA and is responsible for the management of
UGA.

On April
13, 2007, the General Partner formed the United States Heating Oil Fund, LP
(“USHO”), also a limited partnership that is a commodity pool and issues units
traded on the NYSE Arca. The investment objective of USHO is for the
changes in percentage terms of its units’ NAV to reflect the changes in
percentage terms of the spot price of heating oil (also known as No. 2 fuel oil)
delivered to the New York harbor, as measured by the changes in the price of the
futures contract on heating oil traded on the NYMEX, less USHO’s expenses.
USHO’s units began trading on April 9, 2008. The General Partner is the
general partner of USHO and is responsible for the management of
USHO.





On June
30, 2008, the General Partner formed the United States Short Oil Fund, LP
(“USSO”), also a limited partnership that is a commodity pool and issues units
traded on the NYSE Arca.  The investment objective of USSO is for the
changes in percentage terms of its units’ NAV to inversely reflect the changes
in percentage terms of the spot price of light, sweet crude oil delivered to
Cushing, Oklahoma, as measured by the changes in the price of the futures
contract on light, sweet crude oil as traded on the NYMEX, less USSO’s
expenses.  USSO’s units began trading on September 24, 2009. The
General Partner is the general partner of USSO and is responsible for the
management of USSO.





On June
27, 2007, the General Partner formed the United States 12 Month Natural Gas
Fund, LP (“US12NG”), also a limited partnership that is a commodity pool and
issues units traded on the NYSE Arca. The investment objective of US12NG is for
the changes in percentage terms of its units’ NAV to reflect the changes in
percentage terms of the spot price of natural gas delivered at the Henry
Hub, Louisiana, as measured by the changes in the average of the prices of 12
futures contracts on natural gas traded on the NYMEX, consisting of the
near month contract to expire and the contracts for the following 11 months, for
a total of 12 consecutive months’ contracts, less US12NG’s
expenses.  US12NG’s units began trading on November 18, 2009. The
General Partner is the general partner of US12NG and is responsible for the
management of US12NG.





USOF,
USNG, UGA, USHO, USSO and US12NG are collectively referred to herein as the
“Related Public Funds”.  For more information about each of the
Related Public Funds, investors in US12OF may call 1-800-920-0259 or go online
to www.unitedstatescommodityfunds.com.





The
General Partner has filed a registration statement for two other exchange traded
security funds, the United States Brent Oil Fund, LP (“USBO”) and the United
States Commodity Index Funds Trust (“USCI”). The investment objective of USBO
will be for the daily changes in percentage terms of its units’ NAV to reflect
the daily changes in percentage terms of the spot price of Brent crude oil, as
measured by the changes in the price of the futures contract on Brent crude oil
traded on the ICE Futures, less USBO’s expenses.  The investment
objective of USCI will be for the daily changes in percentage terms of its
units’ NAV to reflect the daily changes in percentage terms of the SummerHaven
Dynamic Commodity Index (“SDCI”) Total Return, less USCI’s
expenses.





The
General Partner is required to evaluate the credit risk of US12OF to the futures
commission merchant, oversee the purchase and sale of US12OF’s units by certain
authorized purchasers (“Authorized Purchasers”), review daily positions and
margin requirements of US12OF and manage US12OF’s investments.  The
General Partner also pays the fees of ALPS Distributors, Inc., which acts as the
marketing agent for US12OF (the “Marketing Agent”), and Brown Brothers Harriman
& Co. (“BBH&Co.”), which acts as the administrator (the “Administrator”)
and the custodian (the “Custodian”) for US12OF.




Limited
partners have no right to elect the General Partner on an annual or any other
continuing basis. If the General Partner voluntarily withdraws, however, the
holders of a majority of US12OF’s outstanding units (excluding for purposes of
such determination units owned, if any, by the withdrawing General Partner
and its affiliates) may elect its successor. The General Partner may not be
removed as general partner except upon approval by the affirmative vote of the
holders of at least 66 and 2/3 percent of US12OF’s outstanding units (excluding
units owned, if any, by the General Partner and its affiliates), subject to
the satisfaction of certain conditions set forth in the LP
Agreement.


2


The
business and affairs of the General Partner are managed by a board of directors
(the “Board”), which is comprised of four management directors, some of whom are
also its executive officers (the “Management Directors”), and three independent
directors who meet the independent director requirements established by the NYSE
Arca and the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
Notwithstanding the foregoing, the Management Directors have the authority to
manage the General Partner pursuant to its limited liability company agreement,
as amended from time to time. Through its Management Directors, the General
Partner manages the day-to-day operations of US12OF. The Board has an audit
committee which is made up of the three independent directors (Peter M.
Robinson, Gordon L. Ellis and Malcolm R. Fobes III). For additional information
relating to the audit committee, please see “Item 10. Directors, Executive
Officers and Corporate Governance – Audit Committee” in this annual report on
Form 10-K.





How
Does US12OF Operate?





The net
assets of US12OF consist primarily of investments in futures contracts for
light, sweet crude oil, but may also consist of investment contracts for other
types of crude oil, heating oil, gasoline, natural gas and other petroleum-based
fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign
exchanges (collectively, “Futures Contracts”). US12OF may also invest in other
crude oil-related investments such as cash-settled options on Futures Contracts,
forward contracts for crude oil, and over-the-counter transactions that are
based on the price of crude oil, heating oil, gasoline, natural gas and other
petroleum-based fuels, Futures Contracts and indices based on the foregoing
(collectively, “Other Crude Oil-Related Investments”). For convenience and
unless otherwise specified, Futures Contracts and Other Crude Oil-Related
Investments collectively are referred to as “Crude Oil Interests” in this annual
report on Form 10-K.




US12OF
invests in Crude Oil Interests to the fullest extent possible without being
leveraged or unable to satisfy its current or potential margin or collateral
obligations with respect to its investments in Futures Contracts and Other Crude
Oil-Related Investments. In pursuing this objective, the primary focus of the
General Partner is the investment in Futures Contracts and the management of
US12OF’s investments in short-term obligations of the United States of two years
or less (“Treasuries”), cash and/or cash equivalents for margining purposes and
as collateral.





The
investment objective of US12OF is for the changes in percentage terms of its
units’ NAV to reflect the changes in percentage terms of the spot price of
light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the
changes in the average of the prices of the Benchmark Futures Contracts, less
US12OF’s expenses. When calculating the daily movement of the average price of
the 12 contracts each contract month is equally weighted. It is not the intent
of US12OF to be operated in a fashion such that its NAV will equal, in dollar
terms, the spot price of light, sweet crude oil or any particular futures
contract based on light, sweet crude oil.





The
General Partner believes that holding futures contracts whose expiration dates
are spread out over a 12 month period of time will cause the total return of
such a portfolio to vary compared to a portfolio that holds only a single
month’s contract (such as the near month contract). In particular, the General
Partner believes that the total return of a portfolio holding contracts with a
range of expiration months will be impacted differently by the price
relationship between different contract months of the same commodity future
compared to the total return of a portfolio consisting of the near month
contract. For example, in cases in which the near month contract’s price is
higher than the price of contracts that expire later in time (a situation known
as “backwardation” in the futures markets), then absent the impact of the
overall movement in crude oil prices the value of the near month contract would
tend to rise as it approaches expiration. Conversely, in cases in which the near
month contract’s price is lower than the price of contracts that expire later in
time (a situation known as “contango” in the futures markets), then absent the
impact of the overall movement in crude oil prices the value of the near month
contract would tend to decline as it approaches expiration. The total return of
a portfolio that owned the near month contract and “rolled” forward each month
by selling the near month contract as it approached expiration and purchasing
the next month contract to expire would be positively impacted by a
backwardation market, and negatively impacted by a contango market. Depending on
the exact price relationship of the different month’s prices, portfolio
expenses, and the overall movement of crude oil prices, the impact of
backwardation and contango could have a major impact on the total return of such
a portfolio over time. The General Partner believes that based on historical
evidence a portfolio that held futures contracts with a range of expiration
dates spread out over a 12 month period of time would typically be impacted less
by the positive effect of backwardation and the negative effect of contango
compared to a portfolio that held contracts of a single near month. As a result,
absent the impact of any other factors, a portfolio of 12 different monthly
contracts would tend to have a lower total return than a near month only
portfolio in a backwardation market and a higher total return in a contango
market. However there can be no assurance that such historical relationships
would provide the same or similar results in the future.

As a
specific benchmark, the General Partner endeavors to place US12OF’s trades in
Futures Contracts and Other Crude Oil-Related Investments and otherwise manage
US12OF’s investments so that A will be within plus/minus 10 percent of B,
where:





·
            A
      is the average daily change in US12OF’s NAV for any period of 30
      successive valuation days; i.e., any NYSE Arca
      trading day as of which US12OF calculates its NAV,
  and


·
            B
      is the average daily change in the prices of the Benchmark Futures
      Contracts over the same period.





The
General Partner believes that market arbitrage opportunities cause daily changes
in US12OF’s unit price on the NYSE Arca to closely track daily changes in
US12OF’s NAV per unit. The General Partner further believes that changes in
US12OF’s NAV in percentage terms will closely track the changes in percentage
terms in the Benchmark Futures Contracts, less US12OF’s expenses. The following
two graphs demonstrate the correlation between the daily and monthly changes in
the NAV of US12OF and the daily and monthly changes in the average of the prices
of the Benchmark Futures Contracts both since the initial public offering of
US12OF’s units on December 6, 2007 through December 31, 2009 and during the last
thirty valuation days ended December 31, 2009.

An
investment in the units provides a means for diversifying an investor’s
portfolio or hedging exposure to changes in oil prices.  An investment
in the units allows both retail and institutional investors to easily gain this
exposure to the crude oil market in a transparent, cost-effective
manner.





The
expected correlation of the price of US12OF’s units, US12OF’s NAV and the price
of the Benchmark Futures Contracts is illustrated in the following
diagram:

The
General Partner employs a “neutral” investment strategy intended to track
changes in the price of the Benchmark Futures Contracts regardless of whether
the price goes up or goes down. US12OF’s “neutral” investment strategy is
designed to permit investors generally to purchase and sell US12OF’s units for
the purpose of investing indirectly in oil in a cost-effective manner, and/or to
permit participants in the oil or other industries to hedge the risk of losses
in their oil-related transactions. Accordingly, depending on the investment
objective of an individual investor, the risks generally associated with
investing in crude oil and/or the risks involved in hedging may exist. In
addition, an investment in US12OF involves the risk that the changes in the
price of US12OF’s units will not accurately track the changes in the Benchmark
Futures Contracts.





The
Benchmark Futures Contracts changes from the near month contract to expire and
the 11 following months to the next month contact to expire and the 11 following
months during one day each month. On that day US12OF will “roll” its positions
by closing, or selling, its oil interests and reinvesting the proceeds from
closing these positions in new oil interests.





The
anticipated monthly dates on which the Benchmark Futures Contracts will be
changed and US12OF’s Other Crude Oil-Related Investments will be “rolled” in
2010 are posted on US12OF’s website at www.unitedstates12monthoilfund.com, and
are subject to change without notice.





US12OF’s
total portfolio composition is disclosed on its website each 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 Crude Oil
Interest, the specific types of Other Crude Oil-Related Investments and
characteristics of such Other Crude Oil-Related Investments, Treasuries, and
amount of the cash and/or cash equivalents held in US12OF’s portfolio. US12OF’s
website is publicly accessible at no charge. US12OF’s assets are held in
segregated accounts pursuant to the Commodity Exchange Act (the “CEA”) and CFTC
regulations.




The units
issued by US12OF may only be purchased by Authorized Purchasers and only in
blocks of 100,000 units called Creation Baskets. The amount of the purchase
payment for a Creation Basket is equal to the aggregate NAV of units in the
Creation Basket. Similarly, only Authorized Purchasers may redeem units and only
in blocks of 100,000 units called Redemption Baskets. The purchase price for
Creation Baskets, and the redemption price for Redemption Baskets is the actual
NAV of the units purchased or redeemed calculated at the end of the business day
when notice for a purchase or redemption is received by US12OF. In addition,
Authorized Purchasers pay US12OF a $1,000 fee for each order placed to create
one or more Creation Baskets or redeem one or more Redemption Baskets. The NYSE
Arca publishes an approximate NAV intra-day based on the prior day’s NAV and the
current price of the Benchmark Futures Contracts, but the basket price is
determined based on the actual NAV at the end of the day.

While
US12OF issues units only in Creation Baskets, units may also be purchased and
sold in much smaller increments on the NYSE Arca. These transactions, however,
are effected at the bid and ask prices established by specialist firm(s). Like
any listed security, units can be purchased and sold at any time a secondary
market is open.

managing US12OF’s assets, the General Partner does not use a technical trading
system that issues buy and sell orders. The General Partner instead employs a
quantitative methodology whereby each time a Creation Basket is sold, the
General Partner purchases Crude Oil Interests, such as the Benchmark Futures
Contracts, that have an aggregate market value that approximates the amount of
Treasuries and/or cash received upon the issuance of the Creation
Basket.





As an
example, assume that a Creation Basket is sold by US12OF, and that US12OF’s
closing NAV per unit is $50.00. In that case, US12OF would receive $5,000,000 in
proceeds from the sale of the Creation Basket ($50.00 NAV per unit multiplied by
100,000 units, and excluding the Creation Basket fee of $1,000). If one were to
assume further that the General Partner wants to invest the entire proceeds from
the Creation Basket in the Benchmark Futures Contracts and that the market value
of the Benchmark Futures Contracts is $59,950, US12OF would be unable to buy the
exact number of Benchmark Futures Contracts with an aggregate market value equal
to $5,000,000. Instead, US12OF would be able to purchase 83 Benchmark Futures
Contracts with an aggregate market value of $4,975,850. Assuming a margin
requirement equal to 10% of the value of the Benchmark Futures Contracts, US12OF
would be required to deposit $497,585 in Treasuries and cash with the futures
commission merchant through which the Benchmark Futures Contracts were
purchased. The remainder of the proceeds from the sale of the Creation Basket,
$4,502,415, would remain invested in cash, cash equivalents, and Treasuries as
determined by the General Partner from time to time based on factors such as
potential calls for margin or anticipated redemptions.





The
specific Futures Contracts purchased depends on various factors, including a
judgment by the General Partner as to the appropriate diversification of
US12OF’s investments in futures contracts with respect to the month of
expiration, and the prevailing price volatility of particular contracts. In
addition, US12OF may make use of a mixture of standard sized futures contracts
as well as the smaller sized “mini” contracts. While the General Partner has
made significant investments in NYMEX Futures Contracts, as US12OF reaches
certain accountability levels or position limits on the NYMEX, or for other
reasons, it may invest in Futures Contracts traded on other exchanges or may
invest in Other Crude Oil-Related Investments such as contracts in the
“over-the-counter” market.





The
General Partner does not anticipate letting US12OF’s Futures Contracts expire
and taking delivery of the underlying commodity. Instead, the General Partner
closes existing positions, e.g., when it changes the
Benchmark Futures Contracts or it otherwise determines it would be appropriate
to do so and reinvests the proceeds in new Futures Contracts. Positions may also
be closed out to meet orders for Redemption Baskets and in such case proceeds
for such baskets will not be reinvested.





By
remaining invested as fully as possible in Futures Contracts or Other Crude
Oil-Related Investments, the General Partner believes that the changes in
percentage terms in US12OF’s NAV will continue to closely track the changes in
percentage terms in the prices of the Benchmark Futures Contracts. The General
Partner believes that certain arbitrage opportunities result in the price of the
units traded on the NYSE Arca closely tracking the NAV of US12OF. Additionally,
oil futures contracts traded on the NYMEX have closely tracked the spot price of
light, sweet crude oil. Based on these expected interrelationships, the General
Partner believes that the changes in the price of US12OF’s units as traded on
the NYSE Arca have closely tracked and will continue to closely track the
changes in the spot price of light, sweet crude oil. For performance data
relating to US12OF’s ability to track its benchmark, see “Management’s
Discussion and Analysis of Financial Condition and Results of Operations –
Tracking US12OF’s Benchmark”.

What
are Futures Contracts?




Futures
Contracts are agreements between two parties.  One party agrees to buy
crude oil 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 Contracts are
traded on the NYMEX in units of 1,000 barrels (a “mini” contract is 500
barrels). The price of Futures Contracts 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.





Certain
typical and significant characteristics of Futures Contracts are discussed
below. Additional risks of investing in Futures Contracts are included in “What
are the Risk Factors Involved with an Investment in US12OF?”





Impact of Accountability Levels,
Position Limits and Price Fluctuation Limits. Futures Contracts
include typical and significant characteristics. Most significantly, the CFTC
and U.S. designated contract markets such as the NYMEX have established
accountability levels and position limits on the maximum net long or net short
futures contracts in commodity interests that any person or group of persons
under common trading control (other than as a hedge, which an investment by
US12OF is not) may hold, own or control. The net position is the difference
between an individual or firm’s open long contracts and open short contracts in
any one commodity. In addition, most U.S. futures exchanges, such as the NYMEX,
limit the daily price fluctuation for Futures Contracts. Currently,
the ICE Futures imposes position and accountability limits that are similar to
those imposed by the NYMEX but does not limit the maximum daily price
fluctuation.





The
accountability levels for the Benchmark Futures Contract and other Futures
Contracts traded on the NYMEX are not a fixed ceiling, but rather a threshold
above which the NYMEX may exercise greater scrutiny and control over an
investor’s positions. The current accountability level for any one month in the
Benchmark Futures Contracts is 10,000 net contracts. In addition, the NYMEX
imposes an accountability level for all months of 20,000 net futures contracts
for investments in futures contracts for light, sweet crude oil. If US12OF and
the Related Public Funds exceed these accountability levels for investments in
the futures contract for light, sweet crude oil, the NYMEX will monitor US12OF’s
and the Related Public Funds’ exposure and ask for further information on their
activities including the total size of all positions, investment and trading
strategy, and the extent of liquidity resources of US12OF and the Related Public
Funds. If deemed necessary by the NYMEX, it could also order US12OF and the
Related Public Funds to reduce their aggregate position back to the
accountability level. In addition, the ICE Futures maintains the same
accountability levels, position limits and monitoring authority for its light,
sweet crude oil contract as the NYMEX. As of December 31, 2009, US12OF and the
Related Public Funds held a net of 13,409 NYMEX Crude Oil Futures CL
contracts.  As of December 31, 2009, US12OF did not hold any Futures
Contracts traded on the ICE Futures.





If the
NYMEX or the ICE Futures orders US12OF to reduce its position back to the
accountability level, or to an accountability level that the NYMEX or the ICE
Futures deems appropriate for US12OF, such an accountability level may impact
the mix of investments in oil interests made by US12OF. To illustrate, assume
that the average price of the Benchmark Futures Contracts and the unit price of
US12OF are each $10, and that the NYMEX has determined that US12OF may not own
more than 10,000 Benchmark Futures Contracts. In such case, US12OF could invest
up to $1 billion of its daily net assets in the Benchmark Futures Contracts
(i.e., $10 per contract
multiplied by 1,000 (a Benchmark Futures Contract is a contract for 1,000
barrels of oil multiplied by 10,000 contracts)) before reaching the
accountability level imposed by the NYMEX. Once the daily net assets of the
portfolio exceed $1 billion in Benchmark Futures Contracts, the portfolio may
not be able to make any further investments in Benchmark Futures Contracts. If
the NYMEX were to impose limits at the $1 billion level (or another level),
US12OF anticipates that it would invest the majority of its assets above that
level in a mix of other Futures Contracts or Other Crude Oil-Related Investments
in order to meet its investment objective.




See
“Risk Factors—Risks Associated With Investing Directly or Indirectly in Crude
Oil—Regulation of the commodity interests and energy markets is extensive and
constantly changing; future regulatory developments are impossible to predict
but may significantly and adversely affect US12OF.”

In
addition to accountability levels, the NYMEX and the ICE Futures impose position
limits on contracts held in the last few days of trading in the near month
contract to expire. It is unlikely that US12OF will run up against such position
limits because US12OF’s investment strategy is to close out its positions and
“roll” from the near month contract to expire to the next month contract
beginning two weeks from expiration of the contract.




U.S.
futures exchanges, including the NYMEX, also limit the amount of price
fluctuation for crude oil Futures Contracts. For example, the NYMEX imposes
a $10.00 per barrel ($10,000 per contract) price fluctuation limit for
Benchmark Futures Contracts. This limit is initially based off the previous
trading day’s settlement price. If any Benchmark Futures Contract is traded,
bid, or offered at the limit for five minutes, trading is halted for five
minutes. When trading resumes it begins at the point where the limit was imposed
and the limit is reset to be $10.00 per barrel in either direction of that
point. If another halt were triggered, the market would continue to be expanded
by $10.00 per barrel in either direction after each successive five-minute
trading halt. There is no maximum price fluctuation limit during any one trading
session.





U.S.
futures exchanges, including the NYMEX, currently do not implement fixed
position limits for Futures Contracts held outside of the last few days of
trading in the near month contract to expire.  However, on January 26,
2010, the CFTC published a proposed rule that, if implemented, would set fixed
position limits on energy Futures Contracts, including the NYMEX Light Sweet
crude oil futures contract, NYMEX Henry Hub natural gas futures contract, NYMEX
New York Harbor No. 2 heating oil futures contract, and NYMEX New York Harbor
gasoline blendstock (“RBOB”) gasoline futures contract, along with any contract
based upon these contracts.  The proposed position limits would be set
as a percentage of the open interest in these contracts for the spot month, any
single month, and all months combined.  Additionally, the proposed
rule would aggregate positions in the enumerated contracts and those based upon
such contracts, including contracts listed on separate
exchanges.  This proposal is currently undergoing a 90-day public
comment period.





US12OF
anticipates that to the extent it invests in Futures Contracts other
than light, sweet crude oil contracts (such as futures contracts for Brent
crude oil, natural gas, heating oil, and gasoline) and Other Crude Oil-Related
Investments, it will enter into various non-exchange-traded derivative contracts
to hedge the short-term price movements of such Futures Contracts and Other
Crude Oil-Related Investments against the current Benchmark Futures
Contracts.

Price Volatility. Despite
daily price limits, the price volatility of Futures Contracts generally has been
historically greater than that for traditional securities such as stocks and
bonds. Price volatility often is greater day-to-day as opposed to intra-day.
Crude oil Futures Contracts tend to be more volatile than stocks and bonds
because price movements for crude oil are more currently and directly influenced
by economic factors for which current data is available and are traded by crude
oil futures traders throughout the day. These economic factors include changes
in interest rates; governmental, agricultural, trade, fiscal, monetary and
exchange control programs and policies; weather and climate conditions; changing
supply and demand relationships; changes in balances of payments and trade; U.S.
and international rates of inflation; currency devaluations and revaluations;
U.S. and international political and economic events; and changes in
philosophies and emotions of market participants. Because US12OF invests a
significant portion of its assets in Futures Contracts, the assets of US12OF,
and therefore the prices of US12OF units, may be subject to greater volatility
than traditional securities.





Marking-to-Market Futures
Positions. Futures Contracts are marked to market at the end of each
trading day and the margin required with respect to such contracts is adjusted
accordingly. This process of marking-to-market is designed to prevent losses
from accumulating in any futures account. Therefore, if US12OF’s futures
positions have declined in value, US12OF may be required to post additional
variation margin to cover this decline. Alternatively, if US12OF futures
positions have increased in value, this increase will be credited to US12OF’s
account.




What
is the Crude Oil Market and the Petroleum-Based Fuel Market?





US12OF
may purchase Futures Contracts traded on the NYMEX that are based on light,
sweet crude oil. It may also purchase contracts on other exchanges, including
the ICE Futures and the Singapore Exchange. The NYMEX contracts provide for
delivery of several grades of domestic and internationally traded foreign
crudes, and, among other things, serve the diverse needs of the physical market.
In Europe, Brent crude oil is the standard for futures contracts and is
primarily traded on the ICE Futures. Brent crude oil is the price reference for
two-thirds of the world’s traded oil. The ICE Brent Futures is a deliverable
contract with an option to cash settle which trades in units of 1,000 barrels
(42,000 U.S. gallons). The ICE Futures also offers a WTI Futures contract which
trades in units of 1,000 barrels. The WTI Futures contract is cash settled
against the prevailing market price for U.S. light sweet crude oil.





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, 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
conflict in Iraq 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.





Heating Oil.Heating oil,
also known as No. 2 fuel oil, accounts for about 25% of the yield of a barrel of
crude oil, the second largest “cut” from oil after gasoline. The 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 trading center. The price of heating oil has historically
been volatile.





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.


11




Natural
Gas.  Natural gas accounts for almost a quarter of U.S. energy
consumption. The natural gas futures contract listed and traded on the
NYMEX 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. The price of natural gas has historically been
volatile.





Why
Does US12OF Purchase and Sell Futures Contracts?




US12OF’s
investment objective is for the changes in percentage terms of its units’ NAV to
reflect the changes in percentage terms of the Benchmark Futures Contracts, less
US12OF’s expenses. US12OF invests primarily in Futures Contracts. US12OF seeks
to have its aggregate NAV approximate at all times the aggregate market value of
the Futures Contracts (or Other Crude Oil-Related Investments) it
holds.





Other
than investing in Futures Contracts and Other Crude Oil-Related Investments,
US12OF only invests in assets to support these investments in oil interests. At
any given time, most of US12OF’s investments are in Treasuries, cash and/or cash
equivalents that serve as segregated assets supporting US12OF’s positions in
Futures Contracts and Other Crude Oil-Related Investments. For example, the
purchase of a Futures Contract with a stated value of $10 million would not
require US12OF to pay $10 million upon entering into the contract; rather, only
a margin deposit, generally of 10% to 20% of the stated value of the Futures
Contract, would be required. To secure its Futures Contract obligations, US12OF
would deposit the required margin with the futures commission merchant and would
separately hold, through its Custodian, Treasuries, cash and/or cash equivalents
in an amount equal to the balance of the current market value of the contract,
which at the contract’s inception would be $10 million minus the amount of the
margin deposit, or $9 million (assuming a 10% margin).




As a
result of the foregoing, typically 10% to 20% of US12OF’s assets are held as
margin in segregated accounts with a futures commission merchant. In addition to
the Treasuries or cash it posts with the futures commission merchant for the
Futures Contracts it owns, US12OF holds, through the Custodian, Treasuries, cash
and/or cash equivalents that can be posted as margin or as collateral to support
its over-the-counter contracts. US12OF earns interest income from the Treasuries
and/or cash equivalents that it purchases, and on the cash it holds through the
Custodian. US12OF anticipates that the earned interest income will increase the
NAV and limited partners’ capital contribution accounts. US12OF reinvests the
earned interest income, holds it in cash, or uses it to pay its expenses. If
US12OF reinvests the earned interest income, it makes investments that are
consistent with its investment objective.


12


What
is the Flow of Units?











What
are the Trading Policies of US12OF?





Liquidity




US12OF
invests only in Futures Contracts and Other Crude Oil-Related Investments
that are traded in sufficient volume to permit, in the opinion of the General
Partner, ease of taking and liquidating positions in these financial interests.
This can include both standard sized futures contracts as well as smaller sized
mini contracts.


13





Spot
Commodities





While
crude oil Futures Contracts traded on the NYMEX can be physically settled,
US12OF does not intend to take or make physical delivery. US12OF may from time
to time trade in Other Crude Oil-Related Investments, including contracts based
on the spot price of crude oil.





Leverage





While
US12OF’s historical ratio of initial margin to total assets has generally ranged
from 10% to 20%, the General Partner endeavors to have the value of US12OF’s
Treasuries, cash and/or cash equivalents, whether held by US12OF or posted as
margin or collateral, at all times approximate the aggregate market value of its
obligations under US12OF’s Futures Contracts and Other Crude Oil-Related
Investments. While the General Partner does not intend to leverage US12OF’s
assets, it is not prohibited from doing so under the LP Agreement.





Borrowings





Borrowings
are not used by US12OF unless US12OF is required to borrow money in the event of
physical delivery, US12OF trades in cash commodities, or for short-term needs
created by unexpected redemptions. US12OF maintains the value of its Treasuries,
cash and/or cash equivalents, whether held by US12OF or posted as margin or
collateral, to at all times approximate the aggregate market value of its
obligations under its Futures Contracts and Other Crude Oil-Related Investments.
US12OF has not established and does not plan to establish credit
lines.





Over-the-Counter
Derivatives (Including Spreads and Straddles)





In
addition to Futures Contracts, there are also a number of listed options on the
Futures Contracts on the principal futures exchanges. These contracts offer
investors and hedgers another set of financial vehicles to use in managing
exposure to the crude oil market. Consequently, US12OF may purchase options on
crude oil futures contracts on these exchanges in pursuing its investment
objective.





In
addition to the Futures Contracts and options on the Futures Contracts, there
also exists an active non-exchange-traded market in derivatives tied to crude
oil. These derivatives transactions (also known as over-the-counter contracts)
are usually entered into between two parties. Unlike most of the exchange-traded
Futures Contracts or exchange-traded options on the Futures Contracts, each
party to such contract bears the credit risk that the other party may not be
able to perform its obligations under its contract.





Some
crude oil-based derivatives transactions contain fairly generic terms and
conditions and are available from a wide range of participants. Other crude
oil-based derivatives have highly customized terms and conditions and are not as
widely available. Many of these over-the-counter contracts are cash-settled
forwards for the future delivery of crude oil- or petroleum-based fuels that
have terms similar to the Futures Contracts. Others take the form of “swaps” in
which the two parties exchange cash flows based on pre-determined formulas tied
to the crude oil spot price, forward crude oil price, the Benchmark Futures
Contract price, or other crude oil futures contract price. For example, US12OF
may enter into over-the-counter derivative contracts whose value will be tied to
changes in the difference between the crude oil spot price, the Benchmark
Futures Contract price, or some other futures contract price traded on the NYMEX
or ICE Futures and the price of other Futures Contracts that may be invested in
by US12OF.





To
protect itself from the credit risk that arises in connection with such
contracts, US12OF may enter into agreements with each counterparty that provide
for the netting of its overall exposure to its counterparty, such as the
agreements published by the International Swaps and Derivatives Association,
Inc. US12OF also may require that the counterparty be highly rated and/or
provide collateral or other credit support to address US12OF’s exposure to the
counterparty.

General Partner assesses or reviews, as appropriate, the creditworthiness of
each potential or existing counterparty to an over-the-counter contract pursuant
to guidelines approved by the General Partner's Board of Directors. Furthermore,
the General Partner, on behalf of U12SOF, only enters into over-the-counter
contracts with counterparties who are, or are affiliates of, (a) banks regulated
by a United States federal bank regulator, (b) broker-dealers regulated by the
U.S. Securities and Exchange Commission (the “SEC”), (c) insurance companies
domiciled in the United States, or (d) producers, users or traders of energy,
whether or not regulated by the CFTC. Any entity acting as a counterparty shall
be regulated in either the United States or the United Kingdom unless otherwise
approved by the General Partner’s Board of Directors after consultation with its
legal counsel. Existing counterparties are also reviewed periodically by the
General Partner.





US12OF
may employ spreads or straddles in its trading to mitigate the differences in
its investment portfolio and its goal of tracking the price of the Benchmark
Futures Contract. US12OF would use a spread when it chooses to take simultaneous
long and short positions in futures written on the same underlying asset, but
with different delivery months. The effect of holding such combined positions is
to adjust the sensitivity of US12OF to changes in the price relationship between
futures contracts which will expire sooner and those that will expire later.
US12OF would use such a spread if the General Partner felt that taking such long
and short positions, when combined with the rest of its holdings, would more
closely track the investment goals of US12OF, or if the General Partner felt it
would lead to an overall lower cost of trading to achieve a given level of
economic exposure to movements in crude oil prices. US12OF would enter into a
straddle when it chooses to take an option position consisting of a long (or
short) position in both a call option and put option. The economic effect of
holding certain combinations of put options and call options can be very similar
to that of owning the underlying futures contracts. US12OF would make use of
such a straddle approach if, in the opinion of the General Partner, the
resulting combination would more closely track the investment goals of US12OF or
if it would lead to an overall lower cost of trading to achieve a given level of
economic exposure to movements in crude oil prices.





US12OF
has not employed any hedging methods since all of its investments have been made
over an exchange. Therefore, US12OF has not been exposed to counterparty
risk.





Pyramiding





US12OF
has not and will not employ the technique, commonly known as pyramiding, in
which the speculator uses unrealized profits on existing positions as variation
margin for the purchase or sale of additional positions in the same or another
commodity interest.

and bonds of HealthSouth, captioned In re HealthSouth
Corporation Stockholder, No. CV-03-BE-1501-S and In re HealthSouth
Corporation Bondholder Litigation, No. CV-03-BE-1502-S. Both complaints

On June
27, 2007, the Securities Division of the Secretary of the Commonwealth of
Massachusetts (“Massachusetts Securities Division”) filed an administrative
complaint (the “Complaint”) and notice of adjudicatory proceeding against UBS
Securities LLC, captioned In The Matter of UBS Securities, LLC, Docket No.
E-2007-0049, which alleges, in sum and substance, that UBS Securities has been
violating the Massachusetts Uniform Securities Act (the “Act”) and related
regulations by providing the advisers for certain hedge funds with gifts and
gratuities in the form of below market office rents, personal loans with below
market interest rates, event tickets, and other perks, in order to induce those
hedge fund advisers to increase or retain their level of prime brokerage fees
paid to UBS Securities. The Complaint seeks a cease and desist order from
conduct that violates the Act and regulations, to censure UBS Securities, to
require UBS Securities to pay an administrative fine of an unspecified amount,
and to find as fact the allegations of the Complaint.





On June
26, 2008, the Massachusetts Securities Division filed an administrative
complaint and notice of adjudicatory proceeding against UBS Securities and UBS
Financial Services, Inc. (“UBS Financial”), captioned In the Matter of UBS
Securities, LLC and UBS Financial Services, Inc., Docket No. 2008-0045, which
alleged that UBS Securities and UBS Financial violated the Act in connection
with the marketing and sale of auction rate securities.





On July
22, 2008, the Texas State Securities board filed an administrative proceeding
against UBS Securities and UBS Financial captioned the Matter of the Dealer
Registrations of UBS Financial Services, Inc. and UBS Securities LLC, SOAH

Court of the State of New York against UBS Securities and UBS Financial
captioned State of New York v. UBS Securities LLC and UBS Financial Services,
Inc., No. 650262/2008, in connection with UBS’s marketing and sale of auction
rate securities. The complaint alleges violations of the anti-fraud provisions
of New York state statutes and seeks a judgment ordering that the firm buy back
auction rate securities from investors at par, disgorgement, restitution and
other remedies.





On August
8, 2008, UBS Securities and UBS Financial reached agreements in principle with
the SEC, the NYAG, the Massachusetts Securities Division and other state
regulatory agencies represented by the North American Securities Administrators
Association (“NASAA”) to restore liquidity to all remaining client’s holdings of
auction rate securities by June 30, 2012. On August 20, 2008, the Texas
proceeding was dismissed and withdrawn. On October 2, 2008, UBS Securities and
UBS Financial entered into a final consent agreement with the Massachusetts
Securities Division settling all allegations in the Massachusetts Securities
Division’s administrative proceeding against UBS Securities and UBS Financial
with regards to the auction rate securities matter. On December 11, 2008, UBS

SEC.

administrative action against UBS Securities relating to a student loan issuer,
the New Hampshire Higher Education Loan Corp. (“NHHELCO”). The complaint alleges
fraudulent and unethical conduct in violation of New Hampshire state statues.
The complaint seeks an administrative fine, a cease and desist order, and
restitution to NHHELCO. The claim does not impact the global settlement with the
SEC, NYAG and NASAA relating to the marketing and sale of auction rate
securities to investors.





Further,
UBS Securities, like most full service investment banks and broker-dealers,
receives inquiries and is sometimes involved in investigations by the SEC,
FINRA, the New York Stock Exchange (the “NYSE”) and various other regulatory
organizations, exchanges and government agencies. UBS Securities fully
cooperates with the authorities in all such requests. UBS Securities regularly
discloses to the FINRA arbitration awards, disciplinary action and regulatory
events. These disclosures are publicly available on the FINRA’s website at
www.finra.org. Actions with respect to UBS Securities’ futures commission
merchant business are publicly available on the website of the National Futures
Association (http://www.nfa.futures.org/).





UBS
Securities will act only as clearing broker for US12OF and as such will be paid
commissions for executing and clearing trades on behalf of US12OF. UBS
Securities has not passed upon the adequacy or accuracy of this annual report on
Form 10-K. UBS Securities neither will act in any supervisory capacity with
respect to the General Partner nor participate in the management of the General
Partner or US12OF.





UBS
Securities is not affiliated with US12OF or the General Partner. Therefore,
US12OF does not believe that US12OF has any conflicts of interest with UBS
Securities or their trading principals arising from their acting as US12OF’s
futures commission merchant.





Currently,
the General Partner does not employ commodity trading advisors. If, in the
future, the General Partner does employ commodity trading advisors, it will
choose each advisor based on arm’s-length negotiations and will consider the
advisor’s experience, fees, and reputation.

Other
Fees.  US12OF also pays the fees and expenses associated with
its tax accounting and reporting requirements with the exception of certain
initial implementation service fees and base service fees which are paid by the
General Partner.  These fees are estimated to be $290,000 for the
fiscal year ended December 31, 2009.  In addition, US12OF is
responsible for the fees and expenses, which may include director and officers’
liability insurance, of the independent directors of the General Partner in
connection with their activities with respect to US12OF.  These
director fees and expenses may be shared with other funds managed by the General
Partner.  These fees and expenses for 2009 were $433,046, and US12OF’s
portion of such fees was $12,326.





Form
of Units




Registered
Form. Units are issued in registered form in accordance with the LP
Agreement. The Administrator has been appointed registrar and transfer agent for
the purpose of transferring units in certificated form. The Administrator keeps
a record of all limited partners and holders of the units in certificated form
in the registry (the “Register”). The General Partner recognizes transfers of
units in certificated form only if done in accordance with the LP Agreement. The
beneficial interests in such units are held in book-entry form through
participants and/or accountholders in the Depository Trust Company
(“DTC”).




Book
Entry. Individual certificates are not issued for the units. Instead,
units are represented by one or more global certificates, which are deposited by
the Administrator with DTC and registered in the name of Cede & Co., as
nominee for DTC. The global certificates evidence all of the units outstanding
at any time. Unitholders are limited to (1) participants in DTC such as
banks, brokers, dealers and trust companies (“DTC Participants”), (2) those
who maintain, either directly or indirectly, a custodial relationship with a DTC
Participant (“Indirect Participants”), and (3) those banks, brokers,
dealers, trust companies and others who hold interests in the units through DTC
Participants or Indirect Participants, in each case who satisfy the requirements
for transfers of units. DTC Participants acting on behalf of investors holding
units through such participants’ accounts in DTC will follow the delivery
practice applicable to securities eligible for DTC’s Same-Day Funds Settlement
System. Units are credited to DTC Participants’ securities accounts following
confirmation of receipt of payment.




DTC. DTC
is a limited purpose trust company organized under the laws of the State of New
York and is a member of the Federal Reserve System, a “clearing corporation”
within the meaning of the New York Uniform Commercial Code and a “clearing
agency” registered pursuant to the provisions of Section 17A of the Exchange
Act. DTC holds securities for DTC Participants and facilitates the clearance and
settlement of transactions between DTC Participants through electronic
book-entry changes in accounts of DTC Participants.





Transfer
of Units




Transfers of
Units Only Through DTC. The units are only transferable through the
book-entry system of DTC. Limited partners who are not DTC Participants may
transfer their units through DTC by instructing the DTC Participant holding
their units (or by instructing the Indirect Participant or other entity through
which their units are held) to transfer the units. Transfers are made in
accordance with standard securities industry practice.




Transfers
of interests in units with DTC are made in accordance with the usual rules and
operating procedures of DTC and the nature of the transfer. DTC has established
procedures to facilitate transfers among the participants and/or accountholders
of DTC. Because DTC can only act on behalf of DTC Participants, who in turn act
on behalf of Indirect Participants, the ability of a person or entity having an
interest in a global certificate to pledge such interest to persons or entities
that do not participate in DTC, or otherwise take actions in respect of such
interest, may be affected by the lack of a definitive security in respect of
such interest.


19




DTC has
advised US12OF that it will take any action permitted to be taken by a
unitholder (including, without limitation, the presentation of a global
certificate for exchange) only at the direction of one or more DTC Participants
in whose account with DTC interests in global certificates are credited and only
in respect of such portion of the aggregate principal amount of the global
certificate as to which such DTC Participant or Participants has or have given
such direction.




Transfer/Application
Requirements. All purchasers of US12OF’s units, and potentially any
purchasers of units in the future, who wish to become limited partners or other
record holders and receive cash distributions, if any, or have certain other
rights, must deliver an executed transfer application in which the purchaser or
transferee must certify that, among other things, he, she or it agrees to be
bound by US12OF’s LP Agreement and is eligible to purchase US12OF’s securities.
Each purchaser of units must execute a transfer application and certification.
The obligation to provide the form of transfer application is imposed on the
seller of units or, if a purchase of units is made through an exchange, the form
may be obtained directly through US12OF. Further, the General Partner may
request each record holder to furnish certain information, including that
holder’s nationality, citizenship or other related status. A record holder is a
unitholder that is, or has applied to be, a limited partner. An investor who is
not a U.S. resident may not be eligible to become a record holder or one of
US12OF’s limited partners if that investor’s ownership would subject US12OF to
the risk of cancellation or forfeiture of any of US12OF’s assets under any
federal, state or local law or regulation. If the record holder fails to furnish
the information or if the General Partner determines, on the basis of the
information furnished by the holder in response to the request, that such holder
is not qualified to become one of US12OF’s limited partners, the General Partner
may be substituted as a holder for the record holder, who will then be treated
as a non-citizen assignee, and US12OF will have the right to redeem those
securities held by the record holder.




A
transferee’s broker, agent or nominee may complete, execute and deliver a
transfer application and certification. US12OF may, at its discretion, treat the
nominee holder of a unit as the absolute owner. In that case, the beneficial
holder’s rights are limited solely to those that it has against the nominee
holder as a result of any agreement between the beneficial owner and the nominee
holder.




A person
purchasing US12OF’s existing units, who does not execute a transfer application
and certify that the purchaser is eligible to purchase those securities acquires
no rights in those securities other than the right to resell those securities.
Whether or not a transfer application is received or the consent of the General
Partner obtained, US12OF’s units are securities and are transferable according
to the laws governing transfers of securities.





Any
transfer of units will not be recorded by the transfer agent or recognized by
the General Partner unless a completed transfer application is delivered to the
General Partner or the Administrator. When acquiring units, the transferee of
such units that completes a transfer application will:





·
            be
      an assignee until admitted as a substituted limited partner upon the
      consent and sole discretion of the General Partner and the recording of
      the assignment on the books and records of the
  partnership;





·
            automatically
      request admission as a substituted limited
  partner;





·
            agree
      to be bound by the terms and conditions of, and execute, US12OF’s LP
      Agreement;





·
            represent
      that such transferee has the capacity and authority to enter into US12OF’s
      LP Agreement;





·
            grant
      powers of attorney to US12OF’s General Partner and any liquidator of
      US12OF; and





·
            make
      the consents and waivers contained in US12OF’s LP
    Agreement.


20





An
assignee will become a limited partner in respect of the transferred units upon
the consent of US12OF’s General Partner and the recordation of the name of the
assignee on US12OF’s books and records. Such consent may be withheld in the sole
discretion of US12OF’s General Partner.




If
consent of the General Partner is withheld, such transferee shall be an
assignee. An assignee shall have an interest in the partnership equivalent to
that of a limited partner with respect to allocations and distributions,
including, without limitation, liquidating distributions, of the partnership.
With respect to voting rights attributable to units that are held by assignees,
the General Partner shall be deemed to be the limited partner with respect
thereto and shall, in exercising the voting rights in respect of such units on
any matter, vote such units at the written direction of the assignee who is the
record holder of such units. If no such written direction is received, such
units will not be voted. An assignee shall have no other rights of a limited
partner.




Until a
unit has been transferred on US12OF’s books, US12OF and the transfer agent may
treat the record holder of the unit as the absolute owner for all purposes,
except as otherwise required by law or stock exchange regulations.




Withdrawal
of Limited Partners




As
discussed in the LP Agreement, if the General Partner gives at least fifteen
(15) days’ written notice to a limited partner, then the General Partner may for
any reason, in its sole discretion, require any such limited partner to withdraw
entirely from the partnership or to withdraw a portion of its partner capital
account. If the General Partner does not give at least fifteen (15) days’
written notice to a limited partner, then it may only require withdrawal of all
or any portion of the capital account of any limited partner in the following
circumstances: (i) the unitholder made a misrepresentation to the General
Partner in connection with its purchase of units; or (ii) the limited
partner’s ownership of units would result in the violation of any law or
regulations applicable to the partnership or a partner. In these circumstances,
the General Partner without notice may require the withdrawal at any time, or
retroactively. The limited partner thus designated shall withdraw from the
partnership or withdraw that portion of its partner capital account specified,
as the case may be, as of the close of business on such date as determined by
the General Partner. The limited partner thus designated shall be deemed to have
withdrawn from the partnership or to have made a partial withdrawal from its
partner capital account, as the case may be, without further action on the part
of the limited partner and the provisions of the LP Agreement shall
apply.





Calculating
NAV




US12OF’s
NAV is calculated by:





·         Taking
the current market value of its total assets; and





·         Subtracting
any liabilities





BBH&Co.,
the Administrator, calculates the NAV of US12OF once each NYSE Arca trading day.
The NAV for a particular trading day is released after 4:00 p.m. New York time.
Trading during the core trading session on the NYSE Arca typically closes at
4:00 p.m. New York time. The Administrator uses the NYMEX closing price
(determined at the earlier of the close of the NYMEX or 2:30 p.m. New York time)
for the contracts traded on the NYMEX, but calculates or determines the value of
all other US12OF investments as of the earlier of the close of the NYSE Arca or
4:00 p.m. New York time in accordance with the current Administrative Agency
Agreement among BBH&Co., US12OF and the General Partner which is
incorporated by reference into this annual report on Form 10-K.





In
addition, in order to provide updated information relating to US12OF for use by
investors and market professionals, the NYSE Arca calculates and disseminates
throughout the core trading session on each trading day an updated indicative
fund value. The indicative fund value is calculated by using the prior day’s
closing NAV per unit of US12OF as a base and updating that value throughout the
trading day to reflect changes in the most recently reported trade price for the
active light, sweet crude oil Futures Contracts on the NYMEX. The prices
reported for those Futures Contract months are adjusted based on the prior day’s
spread differential between settlement values for the relevant contract and the
spot month contract. In the event that the spot month contract is also the
Benchmark Futures Contract, the last sale price for that contract is not
adjusted. The indicative fund value unit basis disseminated during NYSE Arca
core trading session hours should not be viewed as an actual real time update of
the NAV, because the NAV is calculated only once at the end of each trading day
based upon the relevant end of day values of US12OF’s
investments.


21


The
indicative fund value is disseminated on a per unit basis every 15 seconds
during regular NYSE Arca core trading session hours of 9:30 a.m. New York time
to 4:00 p.m. New York time. The normal trading hours of the NYMEX are 10:00 a.m.
New York time to 2:30 p.m. New York time. This means that there is a gap in time
at the beginning and the end of each day during which US12OF’s units are traded
on the NYSE Arca, but real-time NYMEX trading prices for oil futures contracts
traded on the NYMEX are not available. As a result, during those gaps there will
be no update to the indicative fund value.





The NYSE
Arca disseminates the indicative fund value through the facilities of CTA/CQ
High Speed Lines. In addition, the indicative fund value is published on the
NYSE Arca’s website and is available through on-line information services such
as Bloomberg and Reuters.





Dissemination
of the indicative fund value provides additional information that is not
otherwise available to the public and is useful to investors and market
professionals in connection with the trading of US12OF units on the NYSE Arca.
Investors and market professionals are able throughout the trading day to
compare the market price of US12OF and the indicative fund value. If the market
price of US12OF units diverges significantly from the indicative fund value,
market professionals will have an incentive to execute arbitrage trades. For
example, if US12OF appears to be trading at a discount compared to the
indicative fund value, a market professional could buy US12OF units on the NYSE
Arca and sell short oil futures contracts. Such arbitrage trades can
tighten the tracking between the market price of US12OF and the indicative fund
value and thus can be beneficial to all market participants.




In
addition, other Futures Contracts, Other Crude Oil-Related Investments and
Treasuries held by US12OF are valued by the Administrator, using rates and
points received from client-approved third party vendors (such as Reuters and WM
Company) and advisor quotes. These investments are not included in the
indicative value. The indicative fund value is based on the prior day’s NAV and
moves up and down solely according to changes in near month Futures Contracts
for light, sweet crude oil traded on the NYMEX.





Creation
and Redemption of Units




US12OF
creates and redeems units from time to time, but only in one or more Creation
Baskets or Redemption Baskets. The creation and redemption of baskets are only
made in exchange for delivery to US12OF or the distribution by US12OF of the
amount of Treasuries and any cash represented by the baskets being created or
redeemed, the amount of which is based on the combined NAV of the number of
units included in the baskets being created or redeemed determined after 4:00
p.m. New York time on the day the order to create or redeem baskets is properly
received.




Authorized
Purchasers are the only persons that may place orders to create and redeem
baskets. Authorized Purchasers must be (1) registered broker-dealers or other
securities market participants, such as banks and other financial institutions,
that are not required to register as broker-dealers to engage in securities
transactions as described below, and (2) DTC Participants. To become an
Authorized Purchaser, a person must enter into an Authorized Purchaser Agreement
with the General Partner. The Authorized Purchaser Agreement provides the
procedures for the creation and redemption of baskets and for the delivery of
the Treasuries and any cash required for such creations and redemptions. The
Authorized Purchaser Agreement and the related procedures attached thereto may
be amended by US12OF, without the consent of any limited partner or unitholder
or Authorized Purchaser. Authorized Purchasers pay a transaction fee of $1,000
to US12OF for each order they place to create or redeem one or more baskets.
Authorized Purchasers who make deposits with US12OF in exchange for baskets receive no fees, commissions or other form of compensation or
inducement of any kind from either US12OF or the General Partner, and no such
person will have any obligation or responsibility to the General Partner or
US12OF to effect any sale or resale of units. As of December 31, 2009, 4
Authorized Purchasers had entered into agreements with US12OF.  During
the year ended December 31, 2009, US12OF issued 75 Creation Baskets and redeemed
34 Redemption Baskets.


22


Certain
Authorized Purchasers are expected to have the facility to participate directly
in the physical crude oil market and the crude oil futures market. In some
cases, an Authorized Purchaser or its affiliates may from time to time acquire
crude oil or sell crude oil and may profit in these instances. The General
Partner believes that the size and operation of the crude oil market make it
unlikely that an Authorized Purchaser’s direct activities in the crude oil or
securities markets will impact the price of crude oil, Futures Contracts, or the
price of the units.




Each
Authorized Purchaser is required to be registered as a broker-dealer under the
Exchange Act and is a member in good standing with FINRA, or exempt from being
or otherwise not required to be licensed as a broker-dealer or a member of
FINRA, and qualified to act as a broker or dealer in the states or other
jurisdictions where the nature of its business so requires. Certain Authorized
Purchasers may also be regulated under federal and state banking laws and
regulations. Each Authorized Purchaser has its own set of rules and procedures,
internal controls and information barriers as it determines is appropriate in
light of its own regulatory regime.




Under the
Authorized Purchaser Agreement, the General Partner has agreed to indemnify the
Authorized Purchasers against certain liabilities, including liabilities under
the Securities Act of 1933, as amended, and to contribute to the payments the
Authorized Purchasers may be required to make in respect of those
liabilities.




The
following description of the procedures for the creation and redemption of
baskets is only a summary and an investor should refer to the relevant
provisions of the LP Agreement and the form of Authorized Purchaser Agreement
for more detail, each of which is incorporated by reference into this annual
report on Form 10-K.




Creation
Procedures





On any
business day, an Authorized Purchaser may place an order with the Marketing
Agent to create one or more baskets. For purposes of processing purchase and
redemption orders, a “business day” means any day other than a day when any of
the NYSE Arca, the NYMEX or the NYSE is closed for regular trading. Purchase
orders must be placed by 12:00 p.m. New York time or the close of regular
trading on the NYSE Arca, whichever is earlier. The day on which the Marketing
Agent receives a valid purchase order is the purchase order date.




By
placing a purchase order, an Authorized Purchaser agrees to deposit Treasuries,
cash, or a combination of Treasuries and cash with US12OF as described below.
Prior to the delivery of baskets for a purchase order, the Authorized Purchaser
must also have wired to the Custodian the non-refundable transaction fee due for
the purchase order. Authorized Purchasers may not withdraw a creation
request.




Determination
of Required Deposits





The total
deposit required to create each basket (“Creation Basket Deposit”) is the amount
of Treasuries and/or cash that is in the same proportion to the total assets of
US12OF (net of estimated accrued but unpaid fees, expenses and other
liabilities) on the date the order to purchase is accepted as the number of
units to be created under the purchase order is in proportion to the total
number of units outstanding on the date the order is received. The General
Partner determines, directly in its sole discretion or in consultation with the
Administrator, the requirements for Treasuries and the amount of cash, including
the maximum permitted remaining maturity of a Treasury and proportions of
Treasury and cash that may be included in deposits to create baskets. The
Marketing Agent will publish such requirements at the beginning of each business
day. The amount of cash deposit required is the difference between the aggregate
market value of the Treasuries required to be included in a Creation Basket
Deposit as of 4:00 p.m. New York time on the date the order to purchase is
properly received and the total required deposit.





Delivery
of Required Deposits





An
Authorized Purchaser who places a purchase order is responsible for transferring
to US12OF’s account with the Custodian the required amount of Treasuries and
cash by the end of the third business day following the purchase order date.
Upon receipt of the deposit amount, the Administrator directs DTC to credit the
number of baskets ordered to the Authorized Purchaser’s DTC account on the third
business day following the purchase order date. The expense and risk of delivery
and ownership of Treasuries until such Treasuries have been received by the
Custodian on behalf of US12OF is borne solely by the Authorized
Purchaser.


23


Because
orders to purchase baskets must be placed by 12:00 p.m., New York time, but the
total payment required to create a basket during the continuous offering period
will not be determined until after 4:00 p.m. New York time on the date the
purchase order is received, Authorized Purchasers will not know the total amount
of the payment required to create a basket at the time they submit an
irrevocable purchase order for the basket. US12OF’s NAV and the total amount of
the payment required to create a basket could rise or fall substantially between
the time an irrevocable purchase order is submitted and the time the amount of
the purchase price in respect thereof is determined.





Rejection
of Purchase Orders





The
General Partner acting by itself or through the Marketing Agent may reject a
purchase order or a Creation Basket Deposit if:





·
            it
      determines that the investment alternative available to US12OF at that
      time will not enable it to meet its investment
  objective;





·
            it
      determines that the purchase order or the Creation Basket Deposit is not
      in proper form;





·
            it
      believes that the purchase order or the Creation Basket Deposit would have
      adverse tax consequences to US12OF or its
  unitholders;





·
            the
      acceptance or receipt of the Creation Basket Deposit would, in the opinion
      of counsel to the General Partner, be unlawful;
  or





·
            circumstances
      outside the control of the General Partner, Marketing Agent or Custodian
      make it, for all practical purposes, not feasible to process creations of
      baskets.





None of
the General Partner, Marketing Agent or Custodian will be liable for the
rejection of any purchase order or Creation Basket Deposit.





Redemption
Procedures




The
procedures by which an Authorized Purchaser can redeem one or more baskets
mirror the procedures for the creation of baskets. On any business day, an
Authorized Purchaser may place an order with the Marketing Agent to redeem one
or more baskets. Redemption orders must be placed by 12:00 p.m. New York time or
the close of regular trading on the NYSE, whichever is earlier. A redemption
order so received will be effective on the date it is received in satisfactory
form by the Marketing Agent. The redemption procedures allow Authorized
Purchasers to redeem baskets and do not entitle an individual unitholder to
redeem any units in an amount less than a Redemption Basket, or to redeem
baskets other than through an Authorized Purchaser. By placing a redemption
order, an Authorized Purchaser agrees to deliver the baskets to be redeemed
through DTC’s book-entry system to US12OF not later than 3:00 p.m. New York time
on the third business day following the effective date of the redemption order.
Prior to the delivery of the redemption distribution for a redemption order, the
Authorized Purchaser must also have wired to US12OF’s account at the Custodian
the non-refundable transaction fee due for the redemption order. Authorized
Purchasers may not withdraw a redemption request.





Determination
of Redemption Distribution





The
redemption distribution from US12OF consists of a transfer to the redeeming
Authorized Purchaser of an amount of Treasuries and cash that is in the same
proportion to the total assets of US12OF (net of estimated accrued but unpaid
fees, expenses and other liabilities) on the date the order to redeem is
properly received as the number of units to be redeemed under the redemption
order is in proportion to the total number of units outstanding on the date the
order is received. The General Partner, directly or in consultation with the
Administrator, determines the requirements for Treasuries and the amounts of
cash, including the maximum permitted remaining maturity of a Treasury, and the
proportions of Treasuries and cash that may be included in distributions to
redeem baskets. The Marketing Agent will publish
such requirements as of 4:00 p.m. New York time on the redemption order
date.


24


Delivery
of Redemption Distribution





The
redemption distribution due from US12OF will be delivered to the Authorized
Purchaser by 3:00 p.m. New York time on the third business day following the
redemption order date if, by 3:00 p.m. New York time on such third business day,
US12OF’s DTC account has been credited with the baskets to be redeemed. If
US12OF’s DTC account has not been credited with all of the baskets to be
redeemed by such time, the redemption distribution will be delivered to the
extent of whole baskets received. Any remainder of the redemption distribution
will be delivered on the next business day to the extent of remaining whole
baskets received if US12OF receives the fee applicable to the extension of the
redemption distribution date which the General Partner may, from time to time,
determine and the remaining baskets to be redeemed are credited to US12OF’s DTC
account by 3:00 p.m. New York time on such next business day. Any further
outstanding amount of the redemption order shall be cancelled. Pursuant to
information from the General Partner, the Custodian will also be authorized to
deliver the redemption distribution notwithstanding that the baskets to be
redeemed are not credited to US12OF’s DTC account by 3:00 p.m. New York time on
the third business day following the redemption order date if the Authorized
Purchaser has collateralized its obligation to deliver the baskets through DTC’s
book entry-system on such terms as the General Partner may from time to time
determine.





Suspension
or Rejection of Redemption Orders





The
General Partner may, in its discretion, suspend the right of redemption, or
postpone the redemption settlement date, (1) for any period during which the
NYSE Arca or the NYMEX is closed other than customary weekend or holiday
closings, or trading on the NYSE Arca or the NYMEX is suspended or restricted,
(2) for any period during which an emergency exists as a result of which
delivery, disposal or evaluation of Treasuries is not reasonably practicable, or
(3) for such other period as the General Partner determines to be necessary for
the protection of the limited partners. For example, the General Partner may
determine that it is necessary to suspend redemptions to allow for the orderly
liquidation of US12OF’s assets at an appropriate value to fund a redemption. If
the General Partner has difficulty liquidating its positions, e.g., because of a market
disruption event in the futures markets, a suspension of trading by the exchange
where the futures contracts are listed or an unanticipated delay in the
liquidation of a position in an over-the-counter contract, it may be appropriate
to suspend redemptions until such time as such circumstances are rectified. None
of the General Partner, the Marketing Agent, the Administrator, or the Custodian
will be liable to any person or in any way for any loss or damages that may
result from any such suspension or postponement.





Redemption
orders must be made in whole baskets. The General Partner will reject a
redemption order if the order is not in proper form as described in the
Authorized Purchaser Agreement or if the fulfillment of the order, in the
opinion of its counsel, might be unlawful. The General Partner may also reject a
redemption order if the number of units being redeemed would reduce the
remaining outstanding units to 100,000 units (i.e., one basket) or less, unless
the General Partner has reason to believe that the placer of the redemption
order does in fact possess all the outstanding units and can deliver
them.





Creation
and Redemption Transaction Fee




To
compensate US12OF for its expenses in connection with the creation and
redemption of baskets, an Authorized Purchaser is required to pay a transaction
fee to US12OF of $1,000 per order to create or redeem baskets. An order may
include multiple baskets. The transaction fee may be reduced, increased or
otherwise changed by the General Partner. The General Partner shall notify DTC
of any change in the transaction fee and will not implement any increase in the
fee for the redemption of baskets until 30 days after the date of the
notice.




Tax
Responsibility




Authorized
Purchasers are responsible for any transfer tax, sales or use tax, stamp tax,
recording tax, value added tax or similar tax or governmental charge applicable
to the creation or redemption of baskets, regardless of whether or not such tax
or charge is imposed directly on the Authorized Purchaser, and agree to
indemnify the General Partner and US12OF if they are required by law to pay any
such tax, together with any applicable penalties, additions to tax or interest
thereon.


25


Secondary
Market Transactions




As noted,
US12OF creates and redeems units from time to time, but only in one or more
Creation Baskets or Redemption Baskets. The creation and redemption of baskets
are only made in exchange for delivery to US12OF or the
distribution by US12OF of the amount of Treasuries and cash represented by the
baskets being created or redeemed, the amount of which will be based on the
aggregate NAV of the number of units included in the baskets being created or
redeemed determined on the day the order to create or redeem baskets is properly
received.





As
discussed above, Authorized Purchasers are the only persons that may place
orders to create and redeem baskets. Authorized Purchasers must be registered
broker-dealers or other securities market participants, such as banks and other
financial institutions that are not required to register as broker-dealers to
engage in securities transactions. An Authorized Purchaser is under no
obligation to create or redeem baskets, and an Authorized Purchaser is under no
obligation to offer to the public units of any baskets it does create.
Authorized Purchasers that do offer to the public units from the baskets they
create will do so at per-unit offering prices that are expected to reflect,
among other factors, the trading price of the units on the NYSE Arca, the NAV of
US12OF at the time the Authorized Purchaser purchased the Creation Baskets and
the NAV of the units at the time of the offer of the units to the public,
the supply of and demand for units at the time of sale, and the liquidity of
the Futures Contract market and the market for Other Crude Oil-Related
Investments. The prices of units offered by Authorized Purchasers are expected
to fall between US12OF’s NAV and the trading price of the units on the NYSE Arca
at the time of sale. Units initially comprising the same basket but offered by
Authorized Purchasers to the public at different times may have different
offering prices. An order for one or more baskets may be placed by an Authorized
Purchaser on behalf of multiple clients. Authorized Purchasers who make deposits
with US12OF in exchange for baskets receive no fees, commissions or other form
of compensation or inducement of any kind from either US12OF or the General
Partner, and no such person has any obligation or responsibility to the General
Partner or US12OF to effect any sale or resale of units. Units trade in the
secondary market on the NYSE Arca. Units may trade in the secondary market at
prices that are lower or higher relative to their NAV per unit. The amount of
the discount or premium in the trading price relative to the NAV per unit may be
influenced by various factors, including the number of investors who seek to
purchase or sell units in the secondary market and the liquidity of the Futures
Contracts market and the market for Other Crude Oil-Related Investments. While
the units trade during the core trading session on the NYSE Arca until 4:00 p.m.
New York time, liquidity in the market for Futures Contracts and Other Crude
Oil-Related Investments may be reduced after the close of the NYMEX at 2:30 p.m.
New York time. As a result, during this time, trading spreads, and the resulting
premium or discount, on the units may widen.





Prior
Performance of US12OF





US12OF’s
units began trading on the American Stock Exchange (the “AMEX”) on December 6,
2007 and are offered on a continuous basis. As a result of the acquisition of
the AMEX by NYSE Euronext, US12OF’s units commenced trading on the NYSE Arca on
November 25, 2008. As of December 31, 2009, the total amount of money raised by
US12OF from Authorized Purchasers was $224,069,815; the total number of
Authorized Purchasers was four; the number of baskets purchased by Authorized
Purchasers was 75; the number of baskets redeemed by Authorized Purchasers was
34; and the aggregate amount of units purchased was 7,500,000. For more
information on the performance of US12OF, see the Performance Tables
below.





Since its
initial offering of 11,000,000 units, US12OF has made one subsequent offering of
its units: 100,000,000 units which were registered with the SEC on March
31, 2009. As of December 31, 2009, US12OF had issued 7,500,000 units, 4,100,000
of which were outstanding. As of December 31, 2009, there were 103,500,000 units
registered but not yet issued.





Since the
offering of US12OF units to the public on December 6, 2007 to December 31, 2009,
the simple average daily change in its Benchmark Futures Contracts was -0.004%,
while the simple average daily change in the NAV of US12OF over the same time
period was -0.003%. The average daily difference was 0.001% (or 0.1 basis
points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily
movement of the Benchmark Futures Contracts, the average error in daily tracking
by the NAV was -0.107%, meaning that over this time period US12OF’s tracking
error was within the plus or minus 10% range established as its benchmark
tracking goal.

            The
      monthly rate of return is calculated by dividing the ending NAV of a given
      month by the ending NAV of the previous month, subtracting 1 and
      multiplying this number by 100 to arrive at a percentage increase or
      decrease.

Terms Used in Performance Tables





Draw-down: Losses experienced
over a specified period. Draw-down is measured on the basis of monthly returns
only and does not reflect intra-month figures.





Worst Monthly Percentage
Draw-down: The largest single month loss sustained since inception of
trading.


28


Worst Peak-to-Valley
Draw-down: The largest percentage decline in the NAV per unit over the
history of the fund. This need not be a continuous decline, but can be a series
of positive and negative returns where the negative returns are larger than the
positive returns.  Worst Peak-to-Valley Draw-down represents the
greatest percentage decline from any month-end NAV per unit that occurs without
such month-end NAV per unit being equaled or exceeded as of a subsequent
month-end. For example, if the NAV per unit declined by $1 in each of January
and February, increased by $1 in March and declined again by $2 in April, a
“peak-to-trough drawdown” analysis conducted as of the end of April would
consider that “drawdown” to be still continuing and to be $3 in amount, whereas
if the NAV per unit had increased by $2 in March, the January-February drawdown
would have ended as of the end of February at the $2 level.

The
General Partner is also currently the general partner of the Related Public
Funds. Each of the General Partner and the Related Public Funds is located in
California.





USOF is a
commodity pool and issues units traded on the NYSE Arca. The investment
objective of USOF is for the changes in percentage terms of its units’ NAV to
reflect the changes in percentage terms of the spot price of light, sweet crude
oil delivered to Cushing, Oklahoma, as measured by the changes in the price of
the futures contract on light, sweet crude oil traded on the NYMEX, less USOF’s
expenses. USOF’s units began trading on April 10, 2006 and are offered on a
continuous basis. USOF may invest in a mixture of listed crude oil futures
contracts, other non-listed oil related investments, Treasuries, cash and cash
equivalents. As of December 31, 2009, the total amount of money raised by USOF
from its authorized purchasers was $24,257,292,570; the total number of
authorized purchasers of USOF was 17; the number of baskets purchased by
authorized purchasers of USOF was 4,752; the number of baskets redeemed by
authorized purchasers of USOF was 4,121; and the aggregate amount of units

that is similar to the investment strategy of US12OF, except that its benchmark
is the near month contract to expire for light, sweet crude oil delivered to
Cushing, Oklahoma.





Since the
offering of USOF units to the public on April 10, 2006 to December 31, 2009, the
simple average daily change in its benchmark oil futures contract was -0.027%,
while the simple average daily change in the NAV of USOF over the same time
period was -0.022%. The average daily difference was 0.005% (or 0.5 basis
points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily
movement of the benchmark oil futures contract, the average error in daily
tracking by the NAV was 1.56%, meaning that over this time period USOF’s
tracking error was within the plus or minus 10% range established as its
benchmark tracking goal.





USNG is a

The
General Partner has filed a registration statement for two other exchange traded
security funds, USBO and USCI. The investment objective of USBO will be
for the daily changes in percentage terms of its units’ NAV to reflect the
changes in percentage terms of the spot price of Brent crude oil, as measured by
the changes in the price of the futures contract on Brent crude oil traded on
the ICE Futures, less USBO’s expenses.  The investment objective of
USCI will be for the daily changes in percentage terms of its units’ NAV to
reflect the daily changes in percentage terms of the SDCI Total Return, less
USCI’s expenses.





There are
significant differences between investing in US12OF and the Related Public Funds
and investing directly in the futures market. The General Partner’s results with
US12OF and the Related Public Funds may not be representative of results that
may be experienced with a fund directly investing in futures contracts or other
managed funds investing in futures contracts. Moreover, given the different
investment objectives of US12OF and the Related Public Funds, the performance of
US12OF may not be representative of results that may be experienced by the other
Related Public Funds. For more information on the performance of the Related
Public Funds, see the Performance Tables below.

            The
      monthly rate of return is calculated by dividing the ending NAV of a given
      month by the ending NAV of the previous month, subtracting 1 and
      multiplying this number by 100 to arrive at a percentage increase or
      decrease.

Other
Related Commodity Trading and Investment Management Experience





Until
December 31, 2009, Ameristock Corporation was an affiliate of the General
Partner.  Ameristock Corporation is a California-based registered
investment advisor registered under the Investment Advisers Act of 1940, as
amended, that has been sponsoring and providing portfolio management services to
mutual funds since 1995. Ameristock Corporation is the investment adviser to the
Ameristock Mutual Fund, Inc., a mutual fund registered under the Investment
Company Act of 1940, as amended (the “1940 Act”), that focuses on large cap U.S.
equities that has $219,616,809 in assets as of December 31, 2009. Ameristock
Corporation was also the investment advisor to the Ameristock ETF Trust, an
open-end management investment company registered under the 1940 Act that
consisted of five separate investment portfolios, each of which sought
investment results, before fees and expenses, that corresponded generally to the
price and yield performance of a particular U.S. Treasury securities index owned
and compiled by Ryan Holdings LLC and Ryan ALM, Inc.  The Ameristock
ETF Trust has liquidated each of its investment portfolios and has wound up its
affairs.

Investments





The
General Partner applies substantially all of US12OF’s assets toward trading in
Futures Contracts and Other Crude Oil-Related Investments and investments in
Treasuries, cash and/or cash equivalents. The General Partner has sole authority
to determine the percentage of assets that are:





·
            held
      on deposit with the futures commission merchant or other
      custodian,





·
            used
      for other investments, and





·
            held
      in bank accounts to pay current obligations and as
    reserves.





The
General Partner deposits substantially all of US12OF’s net assets with the
Custodian or other custodian. When US12OF purchases a Futures Contract and
certain exchange traded Other Crude Oil-Related Investments, US12OF is required
to deposit with the selling futures commission merchant on behalf of the
exchange a portion of the value of the contract or other interest as security to
ensure payment for the obligation under oil interests at maturity. This deposit
is known as “margin.” US12OF invests the remainder of its assets equal to the
difference between the margin deposited and the market value of the futures
contract in Treasuries, cash and/or cash equivalents.




US12OF’s
assets are held in segregated accounts pursuant to the CEA and CFTC regulations.
The General Partner believes that all entities that hold or trade US12OF’s
assets are based in the United States and are subject to United States
regulations.




Approximately
10% to 20% of US12OF’s assets have normally been committed as margin for
commodity Futures Contracts. However, from time to time, the percentage of
assets committed as margin may be substantially more, or less, than such range.
The General Partner invests the balance of US12OF’s assets not invested in Crude
Oil Interests or held in margin as reserves to be available for changes in
margin. All interest income is used for US12OF’s benefit.




The
futures commission merchant, a government agency or a commodity exchange could
increase margins applicable to US12OF to hold trading positions at any time.
Moreover, margin is merely a security deposit and has no bearing on the profit
or loss potential for any positions taken.





The Commodity Interest Markets




General





The CEA
governs the regulation of commodity interest transactions, markets and
intermediaries. In December 2000, the CEA was amended by the Commodity Futures
Modernization Act of 2000 (the “CFMA”), which substantially revised the
regulatory framework governing certain commodity interest transactions and the
markets on which they trade. The CEA, as amended by the CFMA, now provides for
varying degrees of regulation of commodity interest transactions depending upon
the variables of the transaction. In general, these variables include (1) the
type of instrument being traded (e.g., contracts for future
delivery, options, swaps or spot contracts), (2) the type of commodity
underlying the instrument (distinctions are made between instruments based on
agricultural commodities, energy and metals commodities and financial
commodities), (3) the nature of the parties to the transaction (retail, eligible
contract participant, or eligible commercial entity), (4) whether the
transaction is entered into on a principal-to-principal or intermediated basis,
(5) the type of market on which the transaction occurs, and (6) whether the
transaction is subject to clearing through a clearing organization. Information
regarding commodity interest transactions, markets and intermediaries, and their
associated regulatory environment, is provided below.




Futures
Contracts




A futures
contract is a standardized contract traded on, or subject to the rules of, an
exchange that calls for the future delivery of a specified quantity and type of
a commodity at a specified time and place. Futures contracts are traded on a
wide variety of commodities, including agricultural products, bonds, stock
indices, interest rates, currencies, energy and metals. The size and terms of
futures contracts on a particular commodity are identical and are not subject to
any negotiation, other than with respect to price and the number of contracts
traded between the buyer and seller.


43




The
contractual obligations of a buyer or seller may generally be satisfied by
taking or making physical delivery of the underlying commodity or by making an
offsetting sale or purchase of an identical futures contract on the same or
linked exchange before the designated date of delivery. The difference between
the price at which the futures contract is purchased or sold and the price paid
for the offsetting sale or purchase, after allowance for brokerage commissions,
constitutes the profit or loss to the trader. Some futures contracts, such as
stock index contracts, settle in cash (reflecting the difference between the
contract purchase/sale price and the contract settlement price) rather than by
delivery of the underlying commodity.





In market
terminology, a trader who purchases a futures contract is long in the market and
a trader who sells a futures contract is short in the market. Before a trader
closes out his long or short position by an offsetting sale or purchase, his
outstanding contracts are known as open trades or open positions. The aggregate
amount of open positions held by traders in a particular contract is referred to
as the open interest in such contract.




Forward
Contracts





A forward
contract is a contractual obligation to purchase or sell a specified quantity of
a commodity at or before a specified date in the future at a specified price
and, therefore, is economically similar to a futures contract. Unlike futures
contracts, however, forward contracts are typically traded in the
over-the-counter markets and are not standardized contracts. Forward contracts
for a given commodity are generally available for various amounts and maturities
and are subject to individual negotiation between the parties involved.
Moreover, generally there is no direct means of offsetting or closing out a
forward contract by taking an offsetting position as one would a futures
contract on a U.S. exchange. If a trader desires to close out a forward contract
position, he generally will establish an opposite position in the contract but
will settle and recognize the profit or loss on both positions simultaneously on
the delivery date. Thus, unlike in the futures contract market where a trader
who has offset positions will recognize profit or loss immediately, in the
forward market a trader with a position that has been offset at a profit will
generally not receive such profit until the delivery date, and likewise a trader
with a position that has been offset at a loss will generally not have to pay
money until the delivery date. In recent years, however, the terms of forward
contracts have become more standardized, and in some instances such contracts
now provide a right of offset or cash settlement as an alternative to making or
taking delivery of the underlying commodity.





The
forward markets provide what has typically been a highly liquid market for
foreign exchange trading, and in certain cases the prices quoted for foreign
exchange forward contracts may be more favorable than the prices for foreign
exchange futures contracts traded on U.S. exchanges. The forward markets are
largely unregulated. Forward contracts are, in general, not cleared or
guaranteed by a third party. Commercial banks participating in trading foreign
exchange forward contracts often do not require margin deposits, but rely upon
internal credit limitations and their judgments regarding the creditworthiness
of their counterparties. In recent years, however, many over-the-counter market
participants in foreign exchange trading have begun to require that their
counterparties post margin.





Further,
as the result of the CFMA, over-the-counter derivative instruments such as
forward contracts and swap agreements (and options on forwards and physical
commodities) may begin to be traded on lightly-regulated exchanges or electronic
trading platforms that may, but are not required to, provide for clearing
facilities. Exchanges and electronic trading platforms on which over-the-counter
instruments may be traded and the regulation and criteria for that trading are
more fully described below under “Futures Exchanges and Clearing Organizations.”
Nonetheless, absent a clearing facility, US12OF’s trading in foreign exchange
and other forward contracts is exposed to the creditworthiness of the
counterparties on the other side of the trade.





Options
on Futures Contracts




Options
on futures contracts are standardized contracts traded on an exchange. An option
on a futures contract gives the buyer of the option the right, but not the
obligation, to take a position at a specified price (the striking, strike, or
exercise price) in the underlying futures contract or underlying interest. The
buyer of a call option acquires the right, but not the obligation, to purchase
or take a long position in the underlying interest, and the buyer of a put
option acquires the right, but not the obligation, to sell or take a short
position in the underlying interest.


44





The
seller, or writer, of an option is obligated to take a position in the
underlying interest at a specified price opposite to the option buyer if the
option is exercised. Thus, the seller of a call option must stand ready to take
a short position in the underlying interest at the strike price if the buyer
should exercise the option. The seller of a put option, on the other hand, must
stand ready to take a long position in the underlying interest at the strike
price.





A call
option is said to be in-the-money if the strike price is below current market
levels and out-of-the-money if the strike price is above current market levels.
Conversely, a put option is said to be in-the-money if the strike price is above
the current market levels and out-of-the-money if the strike price is below
current market levels.





Options
have limited life spans, usually tied to the delivery or settlement date of the
underlying interest. Some options, however, expire significantly in advance of
such date. The purchase price of an option is referred to as its premium, which
consists of its intrinsic value (which is related to the underlying market
value) plus its time value. As an option nears its expiration date, the time
value shrinks and the market and intrinsic values move into parity. An option
that is out-of-the-money and not offset by the time it expires becomes
worthless. On certain exchanges, in-the-money options are automatically
exercised on their expiration date, but on others unexercised options simply
become worthless after their expiration date.





Regardless
of how much the market swings, the most an option buyer can lose is the option
premium. The option buyer deposits his premium with his broker, and the money
goes to the option seller. Option sellers, on the other hand, face risks similar
to participants in the futures markets. For example, since the seller of a call
option is assigned a short futures position if the option is exercised, his risk
is the same as someone who initially sold a futures contract. Because no one can
predict exactly how the market will move, the option seller posts margin to
demonstrate his ability to meet any potential contractual
obligations.





Options
on Forward Contracts or Commodities





Options
on forward contracts or commodities operate in a manner similar to options on
futures contracts. An option on a forward contract or commodity gives the buyer
of the option the right, but not the obligation, to take a position at a
specified price in the underlying forward contract or commodity. However,
similar to forward contracts, options on forward contracts or on commodities are
individually negotiated contracts between counterparties and are typically
traded in the over-the-counter market. Therefore, options on forward contracts
and physical commodities possess many of the same characteristics of forward
contracts with respect to offsetting positions and credit risk that are
described above.




Swap Contracts




Swap
transactions generally involve contracts between two parties to exchange a
stream of payments computed by reference to a notional amount and the price of
the asset that is the subject of the swap. Swap contracts are principally traded
off-exchange, although recently, as a result of regulatory changes enacted as
part of the CFMA, certain swap contracts are now being traded in electronic
trading facilities and cleared through clearing organizations.





Swaps are
usually entered into on a net basis, that is, the two payment streams are netted
out in a cash settlement on the payment date or dates specified in the
agreement, with the parties receiving or paying, as the case may be, only the
net amount of the two payments. Swaps do not generally involve the delivery of
underlying assets or principal. Accordingly, the risk of loss with respect to
swaps is generally limited to the net amount of payments that the party is
contractually obligated to make. In some swap transactions one or both parties
may require collateral deposits from the counterparty to support that
counterparty’s obligation under the swap agreement. If the counterparty to such
a swap defaults, the risk of loss consists of the net amount of payments that
the party is contractually entitled to receive less any collateral deposits
it is holding.





Some swap
transactions are cleared through central counterparties.  These
transactions, known as cleared swaps, involve two counterparties first agreeing
to the terms of a swap transaction, then submitting the transaction to a
clearing house that acts as the central counterparty.  Once submitted
to the clearing house, the original swap transaction is novated and the central
counterparty becomes the counterparty to a trade with each of the original
parties based upon the trade terms determined in the original
transaction.  In this manner each individual swap counterparty reduces
its risk of loss due to counterparty nonperformance because the clearing house
acts as the counterparty to each transaction.


45





Participants





The two
broad classes of persons who trade commodities are hedgers and speculators.
Hedgers include financial institutions that manage or deal in interest
rate-sensitive instruments, foreign currencies or stock portfolios, and
commercial market participants, such as farmers and manufacturers, that market
or process commodities. Hedging is a protective procedure designed to
effectively lock in prices that would otherwise change due to an adverse
movement in the price of the underlying commodity, for example, the adverse
price movement between the time a merchandiser or processor enters into a
contract to buy or sell a raw or processed commodity at a certain price and the
time he must perform the contract. In such a case, at the time the hedger
contracts to physically sell the commodity at a future date he will
simultaneously buy a futures or forward contract for the necessary equivalent
quantity of the commodity. At the time for performance of the contract, the
hedger may accept delivery under his futures contract and sell the commodity
quantity as required by his physical contract or he may buy the actual
commodity, sell it under the physical contract and close out his position by
making an offsetting sale of a futures contract.





The
commodity interest markets enable the hedger to shift the risk of price
fluctuations. The usual objective of the hedger is to protect the profit that he
expects to earn from farming, merchandising, or processing operations rather
than to profit from his trading. However, at times the impetus for a hedge
transaction may result in part from speculative objectives and hedgers can end
up paying higher prices than they would have, for example, if current market
prices are lower than the locked in price.





Unlike
the hedger, the speculator generally expects neither to make nor take delivery
of the underlying commodity. Instead, the speculator risks his capital with the
hope of making profits from price fluctuations in the commodities. The
speculator is, in effect, the risk bearer who assumes the risks that the hedger
seeks to avoid. Speculators rarely make or take delivery of the underlying
commodity; rather they attempt to close out their positions prior to the
delivery date. Because the speculator may take either a long or short position
in commodities, it is possible for him to make profits or incur losses
regardless of whether prices go up or down.





Futures
Exchanges and Clearing Organizations





Futures
exchanges provide centralized market facilities in which multiple persons have
the ability to execute or trade contracts by accepting bids and offers from
multiple participants. Futures exchanges may provide for execution of trades at
a physical location utilizing trading pits and/or may provide for trading to be
done electronically through computerized matching of bids and offers pursuant to
various algorithms. Members of a particular exchange and the trades executed on
such exchange are subject to the rules of that exchange. Futures exchanges and
clearing organizations are given reasonable latitude in promulgating rules and
regulations to control and regulate their members. Examples of regulations by
exchanges and clearing organizations include the establishment of initial margin
levels, rules regarding trading practices, contract specifications, speculative
position limits, daily price fluctuation limits, and execution and clearing
fees.





Clearing
organizations provide services designed to mutualize or transfer the credit risk
arising from the trading of contracts on an exchange or other electronic trading
facility. Once trades made between members of an exchange or electronic trading
facility have been confirmed, the clearing organization becomes substituted for
the clearing member acting on behalf of each buyer and each seller of contracts
traded on the exchange or trading platform and in effect becomes the other party
to the trade. Thereafter, each clearing member party to the trade looks only to
the clearing organization for performance. The clearing organization generally
establishes some sort of security or guarantee fund to which all clearing
members of the exchange must contribute; this fund acts as an emergency buffer
that is intended to enable the clearing organization to meet its obligations
with regard to the other side of an insolvent clearing member’s contracts.
Furthermore, the clearing organization requires margin deposits and continuously
marks positions to market to provide some assurance that its members will be
able to fulfill their contractual obligations. Thus, a central function of the
clearing organization is to ensure the integrity of trades, and members
effecting transactions on an exchange need not concern themselves with the
solvency of the party on the opposite side of the trade; their only remaining
concerns are the respective solvencies of their own customers, their clearing
broker and the clearing organization. The clearing organizations do not deal
with customers, but only with their member firms and the guarantee of
performance for open positions provided by the clearing organization does not
run to customers.


46





U.S.
Futures Exchanges





Futures
exchanges in the United States are subject to varying degrees of regulation by
the CFTC based on their designation as one of the following: a designated
contract market, a derivatives transaction execution facility, an exempt board
of trade or an electronic trading facility.





A
designated contract market is the most highly regulated level of futures
exchange. Designated contract markets may offer products to retail customers on
an unrestricted basis. To be designated as a contract market, the exchange must
demonstrate that it satisfies specified general criteria for designation, such
as having the ability to prevent market manipulation, rules and procedures to
ensure fair and equitable trading, position limits, dispute resolution
procedures, minimization of conflicts of interest and protection of market
participants. Among the principal designated contract markets in the United
States are the Chicago Board of Trade, the Chicago Mercantile Exchange and the
NYMEX. Each of the designated contract markets in the United States must provide
for the clearance and settlement of transactions with a CFTC-registered
derivatives clearing organization.





A
derivatives transaction execution facility (a “DTEF”) is a new type of exchange
that is subject to fewer regulatory requirements than a designated contract
market but is subject to both commodity interest and participant limitations.
DTEFs limit access to eligible traders that qualify as either eligible contract
participants or eligible commercial entities for futures and option contracts on
commodities that have a nearly inexhaustible deliverable supply, are highly
unlikely to be susceptible to the threat of manipulation, or have no cash
market, security futures products, and futures and option contracts on
commodities that the CFTC may determine, on a case-by-case basis, are highly
unlikely to be susceptible to the threat of manipulation. In addition, certain
commodity interests excluded or exempt from the CEA, such as swaps, etc. may be
traded on a DTEF. There is no requirement that a DTEF use a clearing
organization, except with respect to trading in security futures contracts, in
which case the clearing organization must be a securities clearing agency.
However, if futures contracts and options on futures contracts on a DTEF are
cleared, then it must be through a CFTC-registered derivatives clearing
organization, except that some excluded or exempt commodities traded on a DTEF
may be cleared through a clearing organization other than one registered with
the CFTC.




An exempt
board of trade is also a newly designated form of exchange. An exempt board of
trade is substantially unregulated, subject only to CFTC anti-fraud and
anti-manipulation authority. An exempt board of trade is permitted to trade
futures contracts and options on futures contracts provided that the underlying
commodity is not a security or securities index and has an inexhaustible
deliverable supply or no cash market. All traders on an exempt board of trade
must qualify as eligible contract participants. Contracts deemed eligible to be
traded on an exempt board of trade include contracts on interest rates, exchange
rates, currencies, credit risks or measures, debt instruments, measures of
inflation, or other macroeconomic indices or measures. There is no requirement
that an exempt board of trade use a clearing organization. However, if contracts
on an exempt board of trade are cleared, then it must be through a
CFTC-registered derivatives clearing organization. A board of trade electing to
operate as an exempt board of trade must file a written notification with the
CFTC.





An
electronic trading facility is a new form of trading platform that operates by
means of an electronic or telecommunications network and maintains an automated
audit trail of bids, offers, and the matching of orders or the execution of
transactions on the electronic trading facility. The CEA does not apply to, and
the CFTC has no jurisdiction over, transactions on an electronic trading
facility in certain excluded commodities that are entered into between
principals that qualify as eligible contract participants, subject only to CFTC
anti-fraud and anti-manipulation authority. In general, excluded commodities
include interest rates, currencies, securities, securities indices or other
financial, economic or commercial indices or measures.




47





The
General Partner intends to monitor the development of and opportunities and
risks presented by the new less-regulated exchanges and exempt boards as well as
other trading platforms currently in place or that are being considered by
regulators and may, in the future, allocate a percentage of US12OF’s assets to
trading in products on these exchanges. Provided US12OF maintains assets
exceeding $5 million, US12OF would qualify as an eligible contract participant
and thus would be able to trade on such exchanges.




Non-U.S.
Futures Exchanges





Non-U.S.
futures exchanges differ in certain respects from their U.S. counterparts.
Importantly, non-U.S. futures exchanges are not subject to regulation by the
CFTC, but rather are regulated by their home country regulator. In contrast to
U.S. designated contract markets, some non-U.S. exchanges are principals’
markets, where trades remain the liability of the traders involved, and the
exchange or an affiliated clearing organization, if any, does not become
substituted for any party. Due to the absence of a clearing system, such
exchanges are significantly more susceptible to disruptions. Further,
participants in such markets must often satisfy themselves as to the individual
creditworthiness of each entity with which they enter into a trade. Trading on
non-U.S. exchanges is often in the currency of the exchange’s home jurisdiction.
Consequently, US12OF is subject to the additional risk of fluctuations in the
exchange rate between such currencies and U.S. dollars and the possibility that
exchange controls could be imposed in the future. Trading on non-U.S. exchanges
may differ from trading on U.S. exchanges in a variety of ways and, accordingly,
may subject US12OF to additional risks.





Accountability
Levels and Position Limits





The CFTC
and U.S. designated contract markets have established accountability levels and
position limits on the maximum net long or net short futures contracts in
commodity interests that any person or group of persons under common
trading control (other than a hedger, which US12OF is not) may hold, own or
control. Among the purposes of accountability levels and position limits is to
prevent a corner or squeeze on a market or undue influence on prices by any
single trader or group of traders. The position limits currently established by
the CFTC apply to certain agricultural commodity interests, such as grains
(oats, barley, and flaxseed), soybeans, corn, wheat, cotton, eggs, rye, and
potatoes, but not to interests in energy products. In addition, U.S. exchanges
may set accountability levels and position limits for all commodity interests
traded on that exchange. For example, the current accountability level for
investments at any one time in Futures Contracts for light, sweet crude oil
(including investments in the Benchmark Futures Contract) on the NYMEX is 10,000
contracts for one month and 20,000 contracts for all months. The NYMEX also
imposes position limits on contracts held in the last few days of trading in the
near month contract to expire. The ICE Futures has recently adopted similar
accountability levels and position limits for certain of its Futures Contracts
that are traded on the ICE Futures and settled against the price of a contract
listed for trading on a U.S. designated contract market such as the NYMEX.
Certain exchanges or clearing organizations also set limits on the total net
positions that may be held by a clearing broker. In general, no position limits
are in effect in forward or other over-the-counter contract trading or in
trading on non-U.S. futures exchanges, although the principals with which US12OF
and the clearing brokers may trade in such markets may impose such limits as a
matter of credit policy. For purposes of determining accountability levels and
position limits, US12OF’s commodity interest positions will not be attributable
to investors in their own commodity interest trading.





On
January 26, 2010, the CFTC published a proposed rule that, if implemented, would
set fixed position limits on certain energy Futures Contracts, including the
NYMEX Light Sweet crude oil futures contract, NYMEX Henry Hub natural gas
futures contract, NYMEX New York Harbor No. 2 heating oil futures contract, and
NYMEX RBOB gasoline futures contract, along with any contract based upon these
contracts.  The proposed position limits would be set as a percentage
of the open interest in these contracts for the spot month, any single month,
and all months combined.  Additionally, the proposed rule would
aggregate positions in the enumerated contracts and those based upon such
contracts, including contracts listed on separate exchanges.  This
proposal is currently undergoing a 90-day public comment period.




48





Daily
Price Limits




Most U.S.
futures exchanges (but generally not non-U.S. exchanges) may limit the amount of
fluctuation in some futures contract or options on a futures contract prices
during a single trading day by regulations. These regulations specify what are
referred to as daily price fluctuation limits or, more commonly, daily limits.
The daily limits establish the maximum amount that the price of a futures or
options on a futures contract may vary either up or down from the previous day’s
settlement price. Once the daily limit has been reached in a particular futures
or options on a futures contract, no trades may be made at a price beyond the
limit. Positions in the futures or options contract may then be taken or
liquidated, if at all, only at inordinate expense or if traders are willing to
effect trades at or within the limit during the period for trading on such day.
Because the daily limit rule governs price movement only for a particular
trading day, it does not limit losses and may in fact substantially increase
losses because it may prevent the liquidation of unfavorable positions. Futures
contract prices have occasionally moved to the daily limit for several
consecutive trading days, thus preventing prompt liquidation of positions and
subjecting the trader to substantial losses for those days. The concept of daily
price limits is not relevant to over-the-counter contracts, including forwards
and swaps, and thus such limits are not imposed by banks and others who deal in
those markets.





In
contrast, the NYMEX does not impose daily limits but rather limits the amount of
price fluctuation for Futures Contracts. For example, the NYMEX imposes a
$10.00 per barrel ($10,000 per contract) price fluctuation limit for the
Benchmark  Futures Contract. This limit is initially based off the previous
trading day’s settlement price. If any Benchmark Futures Contract is traded,
bid, or offered at the limit for five minutes, trading is halted for five
minutes. When trading resumes it begins at the point where the limit was imposed
and the limit is reset to be $10.00 per barrel in either direction of that
point. If another halt were triggered, the market would continue to be expanded
by $10.00 per barrel in either direction after each successive five-minute
trading halt. There is no maximum price fluctuation limit during any one trading
session.





Commodity
Prices





Commodity
prices are volatile and, although ultimately determined by the interaction of
supply and demand, are subject to many other influences, including the
psychology of the marketplace and speculative assessments of future world and
economic events. Political climate, interest rates, treaties, balance of
payments, exchange controls and other governmental interventions as well as
numerous other variables affect the commodity markets, and even with
comparatively complete information it is impossible for any trader to predict
reliably commodity prices.





Regulation





Futures
exchanges in the United States are subject to varying degrees of regulation
under the CEA depending on whether such exchange is a designated contract
market, DTEF, exempt board of trade or electronic trading facility. Derivatives
clearing organizations are also subject to the CEA and CFTC regulation. The CFTC
is the governmental agency charged with responsibility for regulation of futures
exchanges and commodity interest trading conducted on those exchanges. The
CFTC’s function is to implement the CEA’s objectives of preventing price
manipulation and excessive speculation and promoting orderly and efficient
commodity interest markets. In addition, the various exchanges and clearing
organizations themselves exercise regulatory and supervisory authority over
their member firms.




The CFTC
possesses exclusive jurisdiction to regulate the activities of CPOs and
commodity trading advisors and has adopted regulations with respect to the
activities of those persons and/or entities. Under the CEA, a registered CPO,
such as the General Partner, is required to make annual filings with the CFTC
describing its organization, capital structure, management and controlling
persons. In addition, the CEA authorizes the CFTC to require and review books
and records of, and documents prepared by, registered CPOs. Pursuant to this
authority, the CFTC requires CPOs to keep accurate, current and orderly records
for each pool that they operate. The CFTC may suspend the registration of a CPO
(1) if the CFTC finds that the operator’s trading practices tend to disrupt
orderly market conditions, (2) if any controlling person of the operator is
subject to an order of the CFTC denying such person trading privileges on any
exchange, and (3) in certain other circumstances. Suspension, restriction or
termination of the General Partner’s registration as a CPO would prevent it,
until that registration were to be reinstated, from managing US12OF, and might
result in the termination of US12OF. US12OF itself is not required to be
registered with the CFTC in any capacity.





The CEA
gives the CFTC similar authority with respect to the activities of commodity
trading advisors. If a trading advisor’s commodity trading advisor registration
were to be terminated, restricted or suspended, the trading advisor would be
unable, until the registration were to be reinstated, to render trading advice
to US12OF.




49





The CEA
requires all futures commission merchants, such as US12OF’s clearing brokers, to
meet and maintain specified fitness and financial requirements, to segregate
customer funds from proprietary funds and account separately for all customers’
funds and positions, and to maintain specified books and records open to
inspection by the staff of the CFTC. The CFTC has similar authority over
introducing brokers, or persons who solicit or accept orders for commodity
interest trades but who do not accept margin deposits for the execution of
trades. The CEA authorizes the CFTC to regulate trading by futures commission
merchants and by their officers and directors, permits the CFTC to require
action by exchanges in the event of market emergencies, and establishes an
administrative procedure under which customers may institute complaints for
damages arising from alleged violations of the CEA. The CEA also gives the
states powers to enforce its provisions and the regulations of the
CFTC.





US12OF’s
investors are afforded prescribed rights for reparations under the CEA.
Investors may also be able to maintain a private right of action for violations
of the CEA. The CFTC has adopted rules implementing the reparation provisions of
the CEA, which provide that any person may file a complaint for a reparations
award with the CFTC for violation of the CEA against a floor broker or a futures
commission merchant, introducing broker, commodity trading advisor, CPO, and
their respective associated persons.





Pursuant
to authority in the CEA, the NFA has been formed and registered with the CFTC as
a registered futures association. At the present time, the NFA is the only
self-regulatory organization for commodity interest professionals, other than
futures exchanges. The CFTC has delegated to the NFA responsibility for the
registration of commodity trading advisors, CPOs, futures commission merchants,
introducing brokers, and their respective associated persons and floor brokers.
The General Partner, each trading advisor, the selling agents and the clearing
brokers are members of the NFA. As such, they are subject to NFA standards
relating to fair trade practices, financial condition and consumer protection.
US12OF itself is not required to become a member of the NFA. As the
self-regulatory body of the commodity interest industry, the NFA promulgates
rules governing the conduct of professionals and disciplines those professionals
that do not comply with these rules. The NFA also arbitrates disputes between
members and their customers and conducts registration and fitness screening of
applicants for membership and audits of its existing members.





The
regulations of the CFTC and the NFA prohibit any representation by a person
registered with the CFTC or by any member of the NFA, that registration with the
CFTC, or membership in the NFA, in any respect indicates that the CFTC or the
NFA, as the case may be, has approved or endorsed that person or that person’s
trading program or objectives. The registrations and memberships of the parties
described in this summary must not be considered as constituting any such
approval or endorsement. Likewise, no futures exchange has given or will give
any similar approval or endorsement.





The
regulation of commodity interest trading in the United States and other
countries is an evolving area of the law. The various statements made in this
summary are subject to modification by legislative action and changes in the
rules and regulations of the CFTC, the NFA, the futures exchanges, clearing
organizations and other regulatory bodies.





The
function of the CFTC is to implement the objectives of the CEA of preventing
price manipulation and other disruptions to market integrity, avoiding systemic
risk, preventing fraud and promoting innovation, competition and financial
integrity of transactions. As mentioned above, this regulation, among other
things, provides that the trading of commodity interest contracts generally must
be upon exchanges designated as contract markets or DTEFs and that all trading
on those exchanges must be done by or through exchange members. Under the CFMA,
commodity interest trading in some commodities between sophisticated persons may
be traded on a trading facility not regulated by the CFTC. As a general matter,
trading in spot contracts, forward contracts, options on forward contracts or
commodities, or swap contracts between eligible contract participants is not
within the jurisdiction of the CFTC and may therefore be effectively
unregulated. The trading advisors may engage in those transactions on behalf of
US12OF in reliance on this exclusion from regulation.  However,
legislation currently under consideration by the U.S. Congress would remove the
exclusion provided to these transactions and place them under federal
regulation.  The proposed legislation would subject these contracts to
new capital, margin, recordkeeping, and reporting
requirements.




In
general, the CFTC does not regulate the interbank and forward foreign currency
markets with respect to transactions in contracts between certain sophisticated
counterparties such as US12OF or between certain regulated institutions and
retail investors. Although U.S. banks are regulated in various ways by the
Federal Reserve Board, the Comptroller of the Currency and other U.S. federal
and state banking officials, banking authorities do not regulate the forward
markets.




50





While the
U.S. government does not currently impose any restrictions on the movements of
currencies, it could choose to do so. The imposition or relaxation of exchange
controls in various jurisdictions could significantly affect the market for that
and other jurisdictions’ currencies. Trading in the interbank market also
exposes US12OF to a risk of default since failure of a bank with which US12OF
had entered into a forward contract would likely result in a default and thus
possibly substantial losses to US12OF.





The CFTC
is prohibited by statute from regulating trading on non-U.S. futures exchanges
and markets. The CFTC, however, has adopted regulations relating to the
marketing of non-U.S. futures contracts in the United States. These regulations
permit certain contracts traded on non-U.S. exchanges to be offered and sold in
the United States.




Commodity
Margin




Original
or initial margin is the minimum amount of funds that must be deposited by a
commodity interest trader with the trader’s broker to initiate and maintain an
open position in futures contracts. Maintenance margin is the amount (generally
less than the original margin) to which a trader’s account may decline before he
must deliver additional margin. A margin deposit is like a cash performance
bond. It helps assure the trader’s performance of the futures contracts that he
or she purchases or sells. Futures contracts are customarily bought and sold on
initial margin that represents a very small percentage (ranging upward from less
than 2%) of the aggregate purchase or sales price of the contract. Because of
such low margin requirements, price fluctuations occurring in the futures
markets may create profits and losses that, in relation to the amount invested,
are greater than are customary in other forms of investment or speculation. As
discussed below, adverse price changes in the futures contract may result in
margin requirements that greatly exceed the initial margin. In addition, the
amount of margin required in connection with a particular futures contract is
set from time to time by the exchange on which the contract is traded and may be
modified from time to time by the exchange during the term of the
contract.





Brokerage
firms, such as US12OF’s clearing brokers, carrying accounts for traders in
commodity interest contracts may not accept lower, and generally require higher,
amounts of margin as a matter of policy to further protect themselves. The
clearing brokers require US12OF to make margin deposits equal to exchange
minimum levels for all commodity interest contracts. This requirement may be
altered from time to time in the clearing brokers’ discretion.





Trading
in the over-the-counter markets where no clearing facility is provided generally
does not require margin but generally does require the extension of credit
between counterparties.  This extension of credit generally takes the
form of transfers of collateral and/or independent amounts. Collateral is
transferred between counterparties during the term of an over-the-counter
transaction based upon the changing value of the transaction, while independent
amounts are fixed amounts posted by one or both counterparties at the start of
an over-the-counter transaction.




When a
trader purchases an option, there is no margin requirement; however, the option
premium must be paid in full. When a trader sells an option, on the other hand,
he or she is required to deposit margin in an amount determined by the margin
requirements established for the underlying interest and, in addition, an amount
substantially equal to the current premium for the option. The margin
requirements imposed on the selling of options, although adjusted to reflect the
probability that out-of-the-money options will not be exercised, can in fact be
higher than those imposed in dealing in the futures markets directly.
Complicated margin requirements apply to spreads and conversions, which are
complex trading strategies in which a trader acquires a mixture of options
positions and positions in the underlying interest.





Margin
requirements are computed each day by a trader’s clearing broker. When the
market value of a particular open commodity interest position changes to a point
where the margin on deposit does not satisfy maintenance margin requirements, a
margin call is made by the broker. If the margin call is not met within a
reasonable time, the broker may close out the trader’s position. With respect to
US12OF’s trading, US12OF (and not its investors personally) is subject to margin
calls.




51





Finally,
many major U.S. exchanges have passed certain cross margining arrangements
involving procedures pursuant to which the futures and options positions held in
an account would, in the case of some accounts, be aggregated and margin
requirements would be assessed on a portfolio basis, measuring the total risk of
the combined positions.

Item 1A.  
Risk Factors.





The
risk factors should be read in connection with the other information included in
this annual report on Form 10-K, including Management’s Discussion and Analysis
of Financial Condition and Results of Operations and US12OF’s financial
statements and the related notes.




Risks
Associated With Investing Directly or Indirectly in Crude Oil





Investing
in oil interests subjects US12OF to the risks of the crude oil industry and this
could result in large fluctuations in the price of US12OF’s units.





US12OF is
subject to the risks and hazards of the crude oil industry because it intends to
invest in Crude Oil Interests. The risks and hazards that are inherent in the
crude oil industry may cause the price of crude oil to widely fluctuate. If
US12OF’s units accurately track the percentage changes in the terms of the
Benchmark Futures Contracts or the spot price of crude oil, then the price of
its units may also fluctuate. The exploration and production of crude oil are
uncertain processes with many risks. The cost of drilling, completing and
operating wells for crude oil is often uncertain, and a number of factors can
delay or prevent drilling operations or production of crude oil,
including:





·
            unexpected
      drilling conditions;





·
            pressure
      or irregularities in formations;





·
            equipment
      failures or repairs;





·
            fires
      or other accidents;




52





·
            adverse
      weather conditions;





·
            pipeline
      ruptures, spills or other supply disruptions;
  and





·
            shortages
      or delays in the availability of drilling rigs and the delivery of
      equipment.





Crude
oil transmission, distribution, gathering, and processing activities involve
numerous risks that may affect the price of crude oil.





There are
a variety of hazards inherent in crude oil transmission, distribution,
gathering, and processing, such as leaks, explosions, pollution, release of
toxic substances, adverse weather conditions (such as hurricanes and flooding),
pipeline failure, abnormal pressures, uncontrollable flows of crude oil,
scheduled and unscheduled maintenance, physical damage to the gathering or
transportation system, and other hazards which could affect the price of crude
oil. To the extent these hazards limit the supply or delivery of crude oil,
crude oil prices will increase.





Changes
in the political climate could have negative consequences for crude oil
prices.





Tensions
with Iran, the world’s fourth largest oil exporter, could put oil exports in
jeopardy. Other global concerns include civil unrest and sabotage affecting the
flow of oil from Nigeria, a large oil exporter. Meanwhile, friction continues
between the governments of the United States and Venezuela, a major exporter of
oil to the United States. Additionally, a series of production cuts by members
of OPEC followed by a refusal to subsequently increase oil production have
tightened world oil markets.





Fluctuations
in the reserve capacity of crude oil could impact future prices.





In the
past, a supply disruption in one area of the world was softened by the ability
of major oil-producing nations such as Saudi Arabia to increase output to make
up the difference. In recent years, much of that spare capacity has been
absorbed by increased demand. The current global economic downturn, however, has
led to a decrease in the demand for oil that lasted through 2009 and a
corresponding increase in spare capacities. According to the United States
Government’s Energy Information Administration, global oil demand is expected to
rise by 0.7 million barrels a day in 2010, compared with a decrease in demand of
1.8 million barrels a day in 2009 and largely unchanged demand in 2008.
Consumption of oil products continues to increase in certain parts of the world,
especially in rapidly growing countries such as India and China, which is now
the world’s second-largest energy user. The volatility of demand in the oil
market makes it difficult to predict the availability of spare
capacities.





The
price of US12OF’s units may be influenced by factors such as the short-term
supply and demand for crude oil and the short-term supply and demand for
US12OF’s units. This may cause the units to trade at a price that is above or
below US12OF’s NAV per unit. Accordingly, changes in the price of units may
substantially vary from the changes in the spot price of light, sweet crude
oil. If this variation occurs, then investors may not be able to effectively use
US12OF as a way to hedge against crude oil-related losses or as a way to
indirectly invest in crude oil.




While it
is expected that the trading prices of the units will fluctuate in accordance
with changes in US12OF’s NAV, the prices of units may also be influenced by
other factors, including the short-term supply and demand for crude oil and the
units. There is no guarantee that the units will not trade at appreciable
discounts from, and/or premiums to, US12OF’s NAV. This could cause changes in
the price of the units to substantially vary from changes in the spot price
of light, sweet crude oil. This may be harmful to investors because if
changes in the price of units vary substantially from changes in the spot price
of light, sweet crude oil, then investors may not be able to effectively
use US12OF as a way to hedge the risk of losses in their crude oil-related
transactions or as a way to indirectly invest in crude oil.




53





Changes
in US12OF’s NAV may not correlate with changes in the average of the prices of
the Benchmark Futures Contracts. If this were to occur, investors may not
be able to effectively use US12OF as a way to hedge against crude oil-related
losses or as a way to indirectly invest in crude oil.




The
General Partner endeavors to invest US12OF’s assets as fully as possible in
short-term Futures Contracts and Other Crude Oil-Related Investments so that the
changes in percentage terms of the NAV closely correlate with the changes in
percentage terms in the average of the prices of the Benchmark Futures
Contracts. However, changes in US12OF’s NAV may not correlate with the changes
in the average of the prices of the Benchmark Futures Contracts for several
reasons as set forth below:





·
            US12OF
      (i) may not be able to buy/sell the exact amount of Futures Contracts and
      Other Crude Oil-Related Investments to have a perfect correlation with
      NAV; (ii) may not always be able to buy and sell Futures Contracts or
      Other Crude Oil-Related Investments at the market price; (iii) may not
      experience a perfect correlation between the spot price of light,
      sweet crude oil and the underlying investments in Futures Contracts, Other
      Crude Oil-Related Investments and Treasuries, cash and/or cash
      equivalents; and (iv) is required to pay fees, including brokerage fees
      and  the management fee, which will have an effect on the
      correlation.





·
            Short-term
      supply and demand for light, sweet crude oil may cause the changes in
      the market price of the Benchmark Futures Contracts to vary from the
      changes in US12OF’s NAV if US12OF has fully invested in Futures Contracts
      that do not reflect such supply and demand and it is unable to replace
      such contracts with Futures Contracts that do reflect such supply and
      demand. In addition, there are also technical differences between the two
      markets, e.g., one is a physical market while the other is a futures
      market traded on exchanges, that may cause variations between the spot
      price of crude oil and the prices of related futures
      contracts.





·
            US12OF
      plans to sell and buy only as many Futures Contracts and Other Crude
      Oil-Related Investments that it can to get the changes in percentage terms
      of the NAV as close as possible to the changes in percentage terms in the
      average of the prices of the Benchmark Futures Contracts. The remainder of
      its assets will be invested in Treasuries, cash and/or cash equivalents
      and will be used to satisfy initial margin and additional margin
      requirements, if any, and to otherwise support its investments in oil
      interests. Investments in Treasuries, cash and/or cash equivalents, both
      directly and as margin, will provide rates of return that will vary from
      changes in the value of the spot price of light, sweet crude oil and
      the average of the prices of the Benchmark Futures
    Contracts.





·
            In
      addition, because US12OF incurs certain expenses in connection with its
      investment activities, and holds most of its assets in more liquid
      short-term securities for margin and other liquidity purposes and for
      redemptions that may be necessary on an ongoing basis, the General Partner
      is generally not able to fully invest US12OF’s assets in Futures Contracts
      or Other Crude Oil-Related Investments and there cannot be perfect
      correlation between changes in US12OF’s NAV and changes in the average of
      the prices of the Benchmark Futures
Contracts.





·
            As
      US12OF grows, there may be more or less correlation. For example, if
      US12OF only has enough money to buy three Benchmark Futures Contracts and
      it needs to buy four contracts to track the price of oil then the
      correlation will be lower, but if it buys 20,000 Benchmark Futures
      Contracts and it needs to buy 20,001 contracts then the correlation will
      be higher. At certain asset levels, US12OF may be limited in its ability
      to purchase the Benchmark Futures Contracts or Other Crude Oil-Related
      Investments due to accountability levels imposed by the relevant
      exchanges. To the extent that US12OF invests in these other Futures
      Contracts or Other Crude Oil-Related Investments, the correlation with the
      Benchmark Futures Contracts may be lower. If US12OF is required to invest
      in other Futures Contracts and Other Crude Oil-Related Investments that
      are less correlated with the Benchmark Futures Contracts, US12OF would
      likely invest in over-the-counter contracts to increase the level of
      correlation of US12OF’s assets. Over-the-counter contracts entail certain
      risks described below under “Over-the-Counter Contract
    Risk.”





·
            US12OF
      will invest in equal amounts of each of the Benchmark Futures Contracts.
      Certain months of these futures contracts may have less liquidity and
      availability than other months of these future contracts. The inability to
      purchase and hold the Benchmark Futures Contracts in equal amounts may
      cause less correlation between the units’ NAV and the average of the
      prices of the Benchmark Futures
Contracts.




54




·
            US12OF
      may not be able to buy the exact number of Futures Contracts and Other
      Crude Oil-Related Investments to have a perfect correlation with the
      Benchmark Futures Contracts if the purchase price of  Futures
      Contracts required to be fully invested in such contracts is higher than
      the proceeds received for the sale of a Creation Basket on the day the
      basket was sold. In such case, US12OF could not invest the entire proceeds
      from the purchase of the Creation Basket in such futures contracts (for
      example, assume US12OF receives $4,000,000 for the sale of a Creation
      Basket and assume that the average of the prices of the Futures Contracts
      for light, sweet crude oil that reflects the prices of the Benchmark
      Futures Contracts is $46.00, then US12OF could only invest in Futures
      Contracts with an aggregate value of $3,956,600). US12OF would be required
      to invest a percentage of the proceeds in cash, Treasuries or other liquid
      securities to be deposited as margin with the futures commission merchant
      through which the contracts were purchased. The remainder of the purchase
      price for the Creation Basket would remain invested in Treasuries, cash
      and/or cash equivalents or other liquid securities as determined by the
      General Partner from time to time based on factors such as potential calls
      for margin or anticipated redemptions. If the trading market for Futures
      Contracts is suspended or closed, US12OF may not be able to purchase these
      investments at the last reported price for such
    investments.





·
            US12OF
      may make use of “mini” contracts as a way of investing a dollar amount in
      contracts that may more closely match the dollar amount of net assets of
      the fund. However, even the use of mini contracts does not completely
      eliminate the risk that US12OF will not be able to buy or sell the exact
      number of Futures Contracts necessary. In addition there is a risk that
      because of the size and relative liquidity of such contracts when compared
      to standard size Futures Contracts such as the Benchmark Futures
      Contracts, the price of a smaller contract for a particular month may not
      equate to the Benchmark Futures Contract for the same month, which could
      cause the change in the US12OF’s per unit price and NAV to vary from
      changes in the average price of the Benchmark Futures
      Contracts.




If
changes in US12OF’s NAV do not correlate with changes in the average of the
prices of the Benchmark Futures Contracts, then investing in US12OF may not be
an effective way to hedge against oil-related losses or indirectly invest in
oil.





The Benchmark Futures Contracts may not correlate with the spot
price of light, sweet crude oil and this could cause changes in the price
of the units to substantially vary from the changes in the spot price of light,
sweet crude oil. If this were to occur, then investors may not be able to
effectively use US12OF as a way to hedge against crude oil-related losses or as
a way to indirectly invest in crude oil.




When
using the Benchmark Futures Contracts as a strategy to track the spot price
of light, sweet crude oil, at best the correlation between changes in
prices of such Crude Oil Interests and the spot price of crude oil can be
only approximate. The degree of imperfection of correlation depends upon
circumstances such as variations in the speculative oil market, supply of and
demand for such Crude Oil Interests and technical influences in oil futures
trading. If there is a weak correlation between the Crude Oil Interests and the
spot price of light, sweet crude oil, then the price of units may not
accurately track the spot price of light, sweet crude oil and investors may
not be able to effectively use US12OF as a way to hedge the risk of losses in
their oil-related transactions or as a way to indirectly invest in crude
oil.





US12OF
may experience a loss if it is required to sell Treasuries at a price lower than
the price at which they were acquired.





The value
of Treasuries generally moves inversely with movements in interest rates. If
US12OF is required to sell Treasuries at a price lower than the price at which
they were acquired, US12OF will experience a loss. This loss may adversely
impact the price of the units and may decrease the correlation between the price
of the units, the prices of the Benchmark Futures Contracts and Other Crude
Oil-Related Investments, and the spot price of light, sweet crude
oil.




55





Certain
of US12OF’s investments could be illiquid which could cause large losses to
investors at any time or from time to time.





At any
given time, US12OF may own 12 different monthly crude oil contracts which have
differing expiration schedules. The amount of liquidity in the crude oil futures
market for each of those months will vary. In some cases certain of those months
may have relatively small amounts of open interest and daily trading volume. As
a result, US12OF may not always be able to liquidate its positions in its
investments at the desired price. It is difficult to execute a trade at a
specific price when there is a relatively small volume of buy and sell orders in
a market. A market disruption, such as a foreign government taking political
actions that disrupt the market in its currency, its crude oil production or
exports, or in another major export, can also make it difficult to liquidate a
position. Alternatively, limits imposed by futures exchanges or other regulatory
organizations, such as accountability levels, position limits and daily price
fluctuation limits, may contribute to a lack of liquidity with respect to some
commodity interests.





Unexpected
market illiquidity may cause major losses to investors at any time or from time
to time. In addition, US12OF has not and does not intend at this time to
establish a credit facility, which would provide an additional source of
liquidity and instead will rely only on the Treasuries, cash and/or cash
equivalents that it holds. The anticipated large value of the positions in
Futures Contracts that the General Partner will acquire or enter into for US12OF
increases the risk of illiquidity. Other Crude Oil-Related Investments that
US12OF invests in, such as negotiated over-the-counter contracts, may have a
greater likelihood of being illiquid since they are contracts between two
parties that take into account not only market risk, but also the relative
credit, tax, and settlement risks under such contracts. Such contracts also have
limited transferability that results from such risks and the contract’s express
limitations.





Because
both Futures Contracts and Other Crude Oil-Related Investments may be illiquid,
US12OF’s Crude Oil Interests may be more difficult to liquidate at favorable
prices in periods of illiquid markets and losses may be incurred during the
period in which positions are being liquidated.





If
the nature of hedgers and speculators in futures markets has shifted such that
crude oil purchasers are the predominant hedgers in the market, US12OF might
have to reinvest at higher futures prices or choose Other Crude Oil-Related
Investments.





The
changing nature of the hedgers and speculators in the crude oil market
influences whether futures prices are above or below the expected future spot
price. In order to induce speculators to take the corresponding long side of the
same futures contract, crude oil producers must generally be willing to sell
futures contracts at prices that are below expected future spot prices.
Conversely, if the predominant hedgers in the futures market are the purchasers
of the crude oil who purchase futures contracts to hedge against a rise in
prices, then speculators will only take the short side of the futures contract
if the futures price is greater than the expected future spot price of crude
oil. This can have significant implications for US12OF when it is time to
reinvest the proceeds from a maturing Futures Contract into a new Futures
Contract.





While
US12OF does not intend to take physical delivery of oil under its Futures
Contracts, physical delivery under such contracts impacts the value of the
contracts.





While it
is not the current intention of US12OF to take to take physical delivery of
crude oil under its Futures Contracts, futures contracts are not required to be
cash-settled and it is possible to take delivery under some of these contracts.
Storage costs associated with purchasing crude oil could result in costs and
other liabilities that could impact the value of Futures Contracts or Other
Crude Oil-Related Investments. Storage costs include the time value of money
invested in crude oil as a physical commodity plus the actual costs of storing
the crude oil less any benefits from ownership of crude oil that are not
obtained by the holder of a futures contract. In general, Futures Contracts have
a one-month delay for contract delivery and the back month (the back month is
any future delivery month other than the spot month) includes storage costs. To
the extent that these storage costs change for crude oil while US12OF holds
Futures Contracts or Other Crude Oil-Related Investments, the value of the
Futures Contracts or Other Crude Oil-Related Investments, and therefore US12OF’s
NAV, may change as well. Because it holds Futures Contracts that will mature up
to 13 months later than the spot or current month, US12OF’s NAV will be impacted
more from the changes in storage costs than would the NAV of a fund that holds
more current futures contracts.




56





The
price relationship between the near month contract and the other monthly
contracts that compose the Benchmark Futures Contracts will vary and may impact
both the total return over time of US12OF’s NAV, as well as the degree to which
its total return tracks other crude oil price indices’ total
returns.





The
Benchmark Futures Contracts consist of the near month contract to expire and the
contracts for the following 11 months, except during the last two weeks of the
current month when the near month contract is sold and replaced by the futures
contract for the thirteenth month following the current month. In the event of a
crude oil futures market where near month contracts trade at a higher price than
the price of contracts that expire later in time, a situation described as
“backwardation” in the futures market, then absent the impact of the overall
movement in crude oil prices the value of the benchmark contract would tend to
rise as it approaches expiration. As a result, the total return of the Benchmark
Futures Contract would tend to track higher. Conversely, in the event of a crude
oil futures market where near month contracts trade at a lower price than the
price of contracts that expire later in time, a situation described as
“contango” in the futures market, then absent the impact of the overall movement
in crude oil prices the value of the benchmark contract would tend to decline as
it approaches expiration. As a result the total return of the Benchmark Futures
Contract would tend to track lower. When compared to total return of other price
indices, such as the spot price of crude oil, the impact of backwardation and
contango may lead the total return of US12OF’s NAV to vary significantly. In the
event of a prolonged period of contango, and absent the impact of rising or
falling oil prices, this could have a significant negative impact on US12OF’s
NAV and total return. Furthermore, a portfolio that consists of twelve different
monthly contracts, ranging in a “strip” from the first month to the twelfth
month, will be impacted differently by contango and backwardation than a
portfolio that consists of just the first month contract.





Because
US12OF’s portfolio will typically hold as many as 12 different crude oil futures
contracts at all times, it may be more expensive for US12OF to buy or sell
futures contracts for its portfolio.





Because
US12OF will typically hold as many as 12 different futures contracts at any one
time, the cost of trading a large number of different contracts could be greater
than the cost of trading the same dollar amount using just one contract. In
addition, the bid/ask spread for buying these different contracts could also on
average be greater than the bid/ask spread for buying a single futures contract
month. This could make it more expensive for US12OF to invest compared to
investing in a single monthly contract. Wider bid/ask spreads and/or higher
commission or brokerage costs would negatively impact an investor’s investment
returns in US12OF.





Because
US12OF’s portfolio will typically hold as many as 12 different crude oil futures
contracts at all times, firms that make a market in the units will also need to
hold multiple contracts when hedging their inventories of units and when
creating or redeeming baskets. This could lead to the units of US12OF trading at
wider bid/ask spreads in the secondary market than an exchange traded security
holding crude oil futures that uses a fewer number of futures contracts at any
given time.





Brokerage
firms or other market participants that make a secondary market in the units of
US12OF may do so by simultaneously hedging their positions by being long, or
short, the same Futures Contracts that US12OF holds in its portfolio. The cost
to brokerage firms or other market participants in putting on and taking off
these hedges is one of the factors that determine the size of the bid/ask spread
they quote on a security such as US12OF. Because US12OF will typically hold as
many as 12 different futures contracts at any one time, the brokerage firms or
other market participants will also find themselves having to trade a number of
different contracts as well. The cost of trading a large number of different
contracts may be greater than the cost of trading the same dollar amount using
just one contract. As a result, the bid/ask spread for US12OF may be wider than
the bid/ask spread for an exchange traded security investing in a fewer number
of futures contracts at any given time. The wider bid/ask spread may negatively
impact an investor’s investment returns in US12OF.





Regulation
of the commodity interests and energy markets is extensive and constantly
changing; future regulatory developments are impossible to predict but may
significantly and adversely affect US12OF.





The
futures markets are subject to comprehensive statutes, regulations, and margin
requirements. In addition, the CFTC and the exchanges are authorized to take
extraordinary actions in the event of a market emergency, including, for
example, the retroactive implementation of speculative position limits or higher
margin requirements, the establishment of daily price limits and the suspension
of trading. The regulation of futures transactions in the United States is a
rapidly changing area of law and is subject to modification by government and
judicial action.




57





The
regulation of commodity interest transactions in the United States is a rapidly
changing area of law and is subject to ongoing modification by governmental and
judicial action. Considerable regulatory attention has been focused on
non-traditional investment pools which are publicly distributed in the United
States. There is a possibility of future regulatory changes altering, perhaps to
a material extent, the nature of an investment in US12OF or the ability of
US12OF to continue to implement its investment strategy. In addition, various
national governments have expressed concern regarding the disruptive effects of
speculative trading in the energy markets and the need to regulate the
derivatives markets in general. The effect of any future regulatory change on
US12OF is impossible to predict, but could be substantial and
adverse.





In the
wake of the economic crisis of 2008 and 2009, the Administration, federal
regulators and Congress are revisiting the regulation of the financial sector,
including securities and commodities markets. These efforts are likely to result
in significant changes in the regulation of these markets.





Currently,
a number of proposals that would alter the regulation of Crude Oil Interests are
being considered by federal regulators and Congress. These proposals include the
imposition of fixed position limits on energy-based commodity futures contracts,
extension of position and accountability limits to futures contracts on non-U.S.
exchanges previously exempt from such limits, and the forced use of
clearinghouse mechanisms for all over-the-counter transactions. Certain
proposals would aggregate and limit all positions in energy futures held by a
single entity, whether such positions exist on U.S. futures exchanges, non-U.S.
futures exchanges, or in over-the-counter contracts. While it cannot be
predicted at this time what reforms will eventually be made or how they will
impact US12OF, if any of the aforementioned proposals are implemented, US12OF’s
ability to meet its investment objective may be negatively impacted and
investors could be adversely affected.





Additionally,
on January 26, 2010, the CFTC published a proposed rule that, if implemented,
would set fixed position limits on certain energy Futures Contracts including
the NYMEX Light Sweet crude oil futures contract, NYMEX Henry Hub natural gas
futures contract, NYMEX New York Harbor No. 2 heating oil futures contract, and
NYMEX RBOB gasoline futures contract, along with any contract based upon these
contracts.  The proposed position limits would be set as a percentage
of the open interest in these contracts for the spot month, any single month,
and all months combined.  Additionally, the proposed rule would
aggregate positions in the enumerated contracts and those based upon such
contracts, including contracts listed on separate exchanges.  This
proposal is currently undergoing a 90-day public comment period.





Investing
in US12OF for purposes of hedging may be subject to several risks including the
possibility of losing the benefit of favorable market movement.





Participants
in the crude oil or in other industries may use US12OF as a vehicle to hedge the
risk of losses in their crude oil-related transactions. There are several risks
in connection with using US12OF as a hedging device. While hedging can provide
protection against an adverse movement in market prices, it can also preclude a
hedger’s opportunity to benefit from a favorable market movement. In a hedging
transaction, the hedger may be concerned that the hedged item will increase in
price, but must recognize the risk that the price may instead decline and if
this happens he will have lost his opportunity to profit from the change in
price because the hedging transaction will result in a loss rather than a gain.
Thus, the hedger foregoes the opportunity to profit from favorable price
movements.





In
addition, if the hedge is not a perfect one, the hedger can lose on the hedging
transaction and not realize an offsetting gain in the value of the underlying
item being hedged.





When
using futures contracts as a hedging technique, at best, the correlation between
changes in prices of futures contracts and of the items being hedged can be only
approximate. The degree of imperfection of correlation depends upon
circumstances such as: variations in speculative markets, demand for futures and
for crude oil products, technical influences in futures trading, and differences
between anticipated energy costs being hedged and the instruments underlying the
standard futures contracts available for trading. Even a well-conceived hedge
may be unsuccessful to some degree because of unexpected market behavior as well
as the expenses associated with creating the hedge.




58





In
addition, using an investment in US12OF as a hedge for changes in energy costs
(e.g., investing in
crude oil, heating oil, gasoline, natural gas or other fuels, or electricity)
may not correlate because changes in the spot price of crude oil may vary from
changes in energy costs because the spot price may not be at the same rate as
changes in the price of other energy products, and, in any case, the price of
crude oil does not reflect the refining, transportation, and other costs that
may impact the hedger’s energy costs.





An
investment in US12OF may provide little or no diversification benefits. Thus, in
a declining market, US12OF may have no gains to offset losses from other
investments, and an investor may suffer losses on an investment in
US12OF while incurring losses with respect to other asset
classes.





Historically,
Futures Contracts and Other Crude Oil-Related Investments have generally been
non-correlated to the performance of other asset classes such as stocks and
bonds. Non-correlation means that there is a low statistically valid
relationship between the performance of futures and other commodity interest
transactions, on the one hand, and stocks or bonds, on the other hand. However,
there can be no assurance that such non-correlation will continue during future
periods. If, contrary to historic patterns, US12OF’s performance were to move in
the same general direction as the financial markets, investors will obtain
little or no diversification benefits from an investment in the units. In such a
case, US12OF may have no gains to offset losses from other investments, and
investors may suffer losses on their investment in US12OF at the same time they
incur losses with respect to other investments.





Variables
such as drought, floods, weather, embargoes, tariffs and other political events
may have a larger impact on crude oil prices and crude oil-linked instruments,
including Futures Contracts and Other Crude Oil-Related Investments, than on
traditional securities. These additional variables may create additional
investment risks that subject US12OF’s investments to greater volatility than
investments in traditional securities.





Non-correlation
should not be confused with negative correlation, where the performance of two
asset classes would be opposite of each other. There is no historic evidence
that the spot price of crude oil and prices of other financial assets, such as
stocks and bonds, are negatively correlated. In the absence of negative
correlation, US12OF cannot be expected to be automatically profitable during
unfavorable periods for the stock market, or vice versa.





US12OF’s
Operating Risks





US12OF
is not a registered investment company so unitholders do not have the
protections of the 1940 Act.





US12OF is
not an investment company subject to the 1940 Act. Accordingly, investors do not
have the protections afforded by that statute which, for example, requires
investment companies to have a majority of disinterested directors and regulates
the relationship between the investment company and its investment
manager.





The
General Partner is leanly staffed and relies heavily on key personnel to manage
trading activities.





In
managing and directing the day-to-day activities and affairs of US12OF, the
General Partner relies heavily on Messrs. Howard Mah and John
Hyland.  If Messrs. Mah or Hyland were to leave or be unable to carry
out their present responsibilities, it may have an adverse effect on the
management of US12OF. Furthermore, Messrs. Mah and Hyland are currently involved
in the management of the Related Public Funds, and the General Partner has filed
a registration statement for two other exchange traded security funds, USBO and
USCI. Mr. Mah is also employed by Ameristock Corporation, a registered
investment adviser that manages a public mutual fund. It is estimated that Mr.
Mah will spend approximately 90% of his time on US12OF and Related Public Fund
matters.  Mr. Hyland will spend approximately 85% of his time on
US12OF and Related Public Fund matters. To the extent that the General Partner
establishes additional funds, even greater demands will be placed on Messrs.
Gerber, Mah and Hyland, as well as the other officers of the General Partner and
its Board of Directors.




59





Accountability levels, position
limits, and daily price fluctuation limits set by the exchanges have the
potential to cause a tracking error, which could cause the price of units to
substantially vary from theaverage of the prices of the Benchmark Futures Contracts
and prevent investors from being able to effectively use US12OF as a way to
hedge against crude oil-related losses or as a way to indirectly invest in crude
oil.





U.S.
designated contract markets such as the NYMEX have established accountability
levels and position limits on the maximum net long or net short futures
contracts in commodity interests that any person or group of persons under
common trading control (other than as a hedge, which an investment by US12OF is
not) may hold, own or control. For example, the current accountability level for
investments at any one time in the Benchmark Futures Contract is 20,000.
While this is not a fixed ceiling, it is a threshold above which the NYMEX may
exercise greater scrutiny and control over an investor, including limiting an
investor to holding no more than 20,000 Benchmark Futures Contracts. With regard
to position limits, the NYMEX limits an investor from holding more than 3,000
net futures in the last 3 days of trading in the near month contract to
expire.





In
addition to accountability levels and position limits, the NYMEX also sets daily
price fluctuation limits on futures contracts. The daily price fluctuation limit
establishes the maximum amount that the price of a futures contract may vary
either up or down from the previous day’s settlement price. Once the daily price
fluctuation limit has been reached in a particular futures contract, no trades
may be made at a price beyond that limit.





For
example, the NYMEX imposes a $10.00 per barrel ($10,000 per contract) price
fluctuation limit for Benchmark Futures Contracts. This limit is initially based
off of the previous trading day’s settlement price. If any Benchmark Futures
Contract is traded, bid, or offered at the limit for five minutes, trading is
halted for five minutes. When trading resumes it begins at the point where the
limit was imposed and the limit is reset to be $10.00 per barrel in either
direction of that point. If another halt were triggered, the market would
continue to be expanded by $10.00 per barrel in either direction after each
successive five-minute trading halt. There is no maximum price fluctuation limit
during any one trading session.





U.S.
futures exchanges, including the NYMEX, currently do not implement fixed
position limits for Futures Contracts held outside of the last few days of
trading in the near month contract to expire.  However, on January 26,
2010, the CFTC published a proposed rule that, if implemented, would set fixed
position limits on energy Futures Contracts, including the NYMEX Light Sweet
crude oil futures contract, NYMEX Henry Hub natural gas futures contract, NYMEX
New York Harbor No. 2 heating oil futures contract, and NYMEX RBOB gasoline
futures contract, along with any contract based upon these
contracts.  The proposed position limits would be set as a percentage
of the open interest in these contracts for the spot month, any single month,
and all months combined.  Additionally, the proposed rule would
aggregate positions in the enumerated contracts and those based upon such
contracts, including contracts listed on separate exchanges.  This
proposal is currently undergoing a 90-day public comment period.





All of
these limits may potentially cause a tracking error between the price of the
units and the average of the prices of the Benchmark Futures Contracts. This may
in turn prevent investors from being able to effectively use US12OF as a way to
hedge against crude oil-related losses or as a way to indirectly invest in crude
oil.





US12OF
has not limited the size of its offering and is committed to utilizing
substantially all of its proceeds to purchase Futures Contracts and Other Crude
Oil-Related Investments. If US12OF encounters accountability levels, position
limits, or price fluctuation limits for Futures Contracts on the NYMEX, it may
then, if permitted under applicable regulatory requirements, purchase Futures
Contracts on the ICE Futures or other exchanges that trade listed crude oil
futures. The Futures Contracts available on the ICE Futures are comparable to
the contracts on the NYMEX, but they may have different underlying commodities,
sizes, deliveries, and prices. In addition, certain of the Futures Contracts
available on the ICE Futures are subject to accountability levels and position
limits.





There
are technical and fundamental risks inherent in the trading system the General
Partner intends to employ.





The
General Partner’s trading system is quantitative in nature and it is possible
that the General Partner might make a mathematical error. In addition, it is
also possible that a computer or software program may malfunction and cause an
error in computation.




60





To
the extent that the General Partner uses spreads and straddles as part of its
trading strategy, there is the risk that the NAV may not closely track the
changes in the Benchmark Futures Contracts.





Spreads
combine simultaneous long and short positions in related futures contracts that
differ by commodity (e.g., long crude oil and
short gasoline), by market (e.g., long WTI crude futures,
short Brent crude futures), or by delivery month (e.g., long December, short
November). Spreads gain or lose value as a result of relative changes in price
between the long and short positions. Spreads often reduce risk to investors,
because the contracts tend to move up or down together. However, both legs of
the spread could move against an investor simultaneously, in which case the
spread would lose value. Certain types of spreads may face unlimited risk e.g., because the price of a
futures contract underlying a short position can increase by an unlimited amount
and the investor would have to take delivery or offset at that
price.





A
commodity straddle takes both long and short option positions in the same
commodity in the same market and delivery month simultaneously. The buyer of a
straddle profits if either the long or the short leg of the straddle moves
further than the combined cost of both options. The seller of a straddle profits
if both the long and short positions do not trade beyond a range equal to the
combined premium for selling both options.





If the
General Partner were to utilize a spread or straddle position and the spread
performed differently than expected, the results could impact US12OF’s tracking
error. This could affect US12OF’s investment objective of having its NAV closely
track the changes in the Benchmark Futures Contracts. Additionally, a loss on a
spread position would negatively impact US12OF’s absolute return.





US12OF
and the General Partner may have conflicts of interest, which may permit them to
favor their own interests to the detriment of unitholders.





US12OF
and the General Partner may have inherent conflicts to the extent the General
Partner attempts to maintain US12OF’s asset size in order to preserve its fee
income and this may not always be consistent with US12OF’s objective of having
the value of its units’ NAV track changes in the Benchmark Futures Contracts.
The General Partner’s officers, directors and employees do not devote their time
exclusively to US12OF. These persons are directors, officers or employees of
other entities that may compete with US12OF for their services. They could have
a conflict between their responsibilities to US12OF and to those other
entities.





In
addition, the General Partner’s principals, officers, directors or employees may
trade futures and related contracts for their own account. A conflict of
interest may exist if their trades are in the same markets and at the same time
as US12OF trades using the clearing broker to be used by US12OF. A potential
conflict also may occur if the General Partner’s principals, officers, directors
or employees trade their accounts more aggressively or take positions in their
accounts which are opposite, or ahead of, the positions taken by
US12OF.





The
General Partner has sole current authority to manage the investments and
operations of US12OF, and this may allow it to act in a way that furthers its
own interests which may create a conflict with the best interests of investors.
Limited partners have limited voting control, which will limit the ability to
influence matters such as amendment of the LP Agreement, change in US12OF’s
basic investment policy, dissolution of this fund, or the sale or distribution
of US12OF’s assets.





The
General Partner serves as the general partner to each of US12OF and the Related
Public Funds and will serve as the general partner for USBO and the sponsor
for USCI, if such funds offer their securities to the public or begin
operations. The General Partner may have a conflict to the extent that its
trading decisions for US12OF may be influenced by the effect they would have on
the other funds it manages. These trading decisions may be influenced since the
General Partner also serves as the general partner for all of the funds and is
required to meet all of the funds’ investment objectives as well as US12OF’s. If
the General Partner believes that a trading decision it made on behalf of US12OF
might (i) impede its other funds from reaching their investment objectives, or
(ii) improve the likelihood of meeting its other funds’ objectives, then the
General Partner may choose to change its trading decision for US12OF, which
could either impede or improve the opportunity for US12OF to meet its investment
objective. In addition, the General Partner is required to indemnify the
officers and directors of its other funds if the need for indemnification
arises. This potential indemnification will cause the General Partner’s assets
to decrease. If the General Partner’s other sources of income are not sufficient
to compensate for the indemnification, then the General Partner may terminate
and investors could lose their investment.




61





Unitholders
may only vote on the removal of the General Partner and limited partners have
only limited voting rights. Unitholders and limited partners will not
participate in the management of US12OF and do not control the General Partner
so they will not have influence over basic matters that affect
US12OF.





Unitholders
that have not applied to become limited partners have no voting rights, other
than to remove the General Partner. Limited partners will have limited voting
rights with respect to US12OF’s affairs. Unitholders may remove the General
Partner only if 66 2/3% of the unitholders elect to do so. Unitholders and
limited partners will not be permitted to participate in the management or
control of US12OF or the conduct of its business. Unitholders and limited
partners must therefore rely upon the duties and judgment of the General Partner
to manage US12OF’s affairs.





The
General Partner may manage a large amount of assets and this could affect
US12OF’s ability to trade profitably.





Increases
in assets under management may affect trading decisions. In general, the General
Partner does not intend to limit the amount of assets of US12OF that it may
manage. The more assets the General Partner manages, the more difficult it may
be for it to trade profitably because of the difficulty of trading larger
positions without adversely affecting prices and performance and of managing
risk associated with larger positions.





US12OF
could terminate at any time and cause the liquidation and potential loss of an
investor’s investment and could upset the overall maturity and timing of
an investor’s investment portfolio.





US12OF
may terminate at any time, regardless of whether US12OF has incurred losses,
subject to the terms of the LP Agreement. In particular, unforeseen
circumstances, including the death, adjudication of incompetence, bankruptcy,
dissolution, or removal of the General Partner could cause US12OF to terminate
unless a majority  in interest of the limited partners within 90 days
of the event elects to continue the partnership and appoints a successor general
partner, or the affirmative vote of a majority in interest of the limited
partners subject to certain conditions. However, no level of losses will require
the General Partner to terminate US12OF. US12OF’s termination would cause the
liquidation and potential loss of an investor’s investment. Termination could
also negatively affect the overall maturity and timing of an investor’s
investment portfolio.





Limited
partners may not have limited liability in certain circumstances, including
potentially having liability for the return of wrongful
distributions.





Under
Delaware law, a limited partner might be held liable for US12OF obligations as
if it were a General Partner if the limited partner participates in the control
of the partnership’s business and the persons who transact business with the
partnership think the limited partner is the General Partner.





A limited
partner will not be liable for assessments in addition to its initial capital
investment in any of US12OF’s capital securities representing units. However, a
limited partner may be required to repay to US12OF any amounts wrongfully
returned or distributed to it under some circumstances. Under Delaware law,
US12OF may not make a distribution to limited partners if the distribution
causes US12OF’s liabilities (other than liabilities to partners on account of
their partnership interests and nonrecourse liabilities) to exceed the fair
value of US12OF’s assets. Delaware law provides that a limited partner who
receives such a distribution and knew at the time of the distribution that the
distribution violated the law will be liable to the limited partnership for the
amount of the distribution for three years from the date of the
distribution.





With
adequate notice, a limited partner may be required to withdraw from the
partnership for any reason.





If the
General Partner gives at least fifteen (15) days’ written notice to a limited
partner, then the General Partner may for any reason, in its sole discretion,
require any such limited partner to withdraw entirely from the partnership or to
withdraw a portion of its partner capital account. The General Partner may
require withdrawal even in situations where the limited partner has complied
completely with the provisions of the LP Agreement.




62





US12OF’s
existing units are, and any units US12OF issues in the future will be, subject
to restrictions on transfer. Failure to satisfy these requirements will preclude
a transferee from being able to have all the rights of a limited
partner.





No
transfer of any unit or interest therein may be made if such transfer would (a)
violate the then applicable federal or state securities laws or rules and
regulations of the SEC, any state securities commission, the CFTC or any other
governmental authority with jurisdiction over such transfer, or (b) cause US12OF
to be taxable as a corporation or affect US12OF’s existence or qualification as
a limited partnership. In addition, investors may only become limited partners
if they transfer their units to purchasers that meet certain conditions outlined
in the LP Agreement, which provides that each record holder or limited partner
or unitholder applying to become a limited partner (each a record holder) may be
required by the General Partner to furnish certain information, including that
holder’s nationality, citizenship or other related status. A transferee who is
not a U.S. resident may not be eligible to become a record holder or a limited
partner if its ownership would subject US12OF to the risk of cancellation or
forfeiture of any of its assets under any federal, state or local law or
regulation. All purchasers of US12OF’s units, who wish to become limited
partners or record holders, and receive cash distributions, if any, or have
certain other rights, must deliver an executed transfer application in which the
purchaser or transferee must certify that, among other things, he, she or it
agrees to be bound by US12OF’s LP Agreement and is eligible to purchase US12OF’s
securities. Any transfer of units will not be recorded by the transfer agent or
recognized by US12OF unless a completed transfer application is delivered to the
General Partner or the Administrator. A person purchasing US12OF’s existing
units, who does not execute a transfer application and certify that the
purchaser is eligible to purchase those securities acquires no rights in those
securities other than the right to resell those securities. Whether or not a
transfer application is received or the consent of the General Partner obtained,
US12OF’s units will be securities and will be transferable according to the laws
governing transfers of securities. See “Transfer of Units.”





US12OF
does not expect to make cash distributions.





The
General Partner has not previously made any cash distributions and intends to
re-invest any realized gains in additional oil interests rather than
distributing cash to limited partners. Therefore, unlike mutual funds, commodity
pools or other investment pools that actively manage their investments in an
attempt to realize income and gains from their investing activities and
distribute such income and gains to their investors, US12OF generally does not
expect to distribute cash to limited partners. An investor should not invest in
US12OF if it will need cash distributions from US12OF to pay taxes on its share
of income and gains of US12OF, if any, or for any other reason. Although US12OF
does not intend to make cash distributions, the income earned from its
investments held directly or posted as margin may reach levels that merit
distribution, e.g., at levels where such income is not necessary to support its
underlying investments in oil interests and investors adversely react to being
taxed on such income without receiving distributions that could be used to pay
such tax. If this income becomes significant then cash distributions may be
made.





There
is a risk that US12OF will not earn trading gains sufficient to compensate for
the fees and expenses that it must pay and as such US12OF may not earn any
profit.





US12OF
pays brokerage charges of approximately 0.03% based on futures commission
merchant fees of $3.50 per buy or sell, management fees of 0.60% of NAV on its
average net assets, and over-the-counter spreads and extraordinary expenses
(e.g., subsequent
offering expenses, other expenses not in the ordinary course of business,
including the indemnification of any person against liabilities and obligations
to the extent permitted by law and required under the LP Agreement and under
agreements entered into by the General Partner on US12OF’s behalf and the
bringing and defending of actions at law or in equity and otherwise engaging in
the conduct of litigation and the incurring of legal expenses and the settlement
of claims and litigation) that can not be quantified. These fees and expenses
must be paid in all cases regardless of whether US12OF’s activities are
profitable. Accordingly, US12OF must earn trading gains sufficient to compensate
for these fees and expenses before it can earn any profit.




63





If
offerings of the units do not raise sufficient funds to pay US12OF’s future
expenses and no other source of funding of expenses is found, US12OF may be
forced to terminate and investors may lose all or part of their
investment.





Prior to
the offering of units that commenced on December 6, 2007, all of US12OF’s
expenses were funded by the General Partner and its affiliates. These payments
by the General Partner and its affiliates were designed to allow US12OF the
ability to commence the public offering of its units. US12OF now directly pays
certain of these fees and expenses. The General Partner will continue to
pay other fees and expenses, as set forth in the LP Agreement. If the General
Partner and US12OF are unable to raise sufficient funds to cover their expenses
or locate any other source of funding, US12OF may be forced to terminate and
investors may lose all or part of their investment.





US12OF
may incur higher fees and expenses upon renewing existing or entering into new
contractual relationships.





The
clearing arrangements between the clearing brokers and US12OF generally are
terminable by the clearing brokers once the clearing broker has given US12OF
notice. Upon termination, the General Partner may be required to renegotiate or
make other arrangements for obtaining similar services if US12OF intends to
continue trading in Futures Contracts or Other Crude Oil-Related Investments at
its present level of capacity. The services of any clearing broker may not be
available, or even if available, these services may not be available on the
terms as favorable as those of the expired or terminated clearing
arrangements.





US12OF
may miss certain trading opportunities because it will not receive the benefit
of the expertise of independent trading advisors.





The
General Partner does not employ trading advisors for US12OF; however, it
reserves the right to employ them in the future. The only advisor to US12OF is
the General Partner. A lack of independent trading advisors may be
disadvantageous to US12OF because it will not receive the benefit of a trading
advisor’s expertise.





An
unanticipated number of redemption requests during a short period of time could
have an adverse effect on the NAV of US12OF.





If a
substantial number of requests for redemption of Redemption Baskets are received
by US12OF during a relatively short period of time, US12OF may not be able to
satisfy the requests from US12OF’s assets not committed to trading. As a
consequence, it could be necessary to liquidate positions in US12OF’s trading
positions before the time that the trading strategies would otherwise dictate
liquidation.





The
financial markets are currently in a period of disruption and US12OF does not
expect these conditions to improve in the near future.





Currently
and throughout 2008 and 2009, the financial markets have experienced very
difficult conditions and volatility as well as significant adverse
trends.  The conditions in these markets have resulted in a decrease
in availability of corporate credit and liquidity and have led indirectly to the
insolvency, closure or acquisition of a number of major financial institutions
and have contributed to further consolidation within the financial services
industry.  A continued recession or a depression could adversely
affect the financial condition and results of operations of US12OF’s service
providers and Authorized Purchasers which would impact the ability of the
General Partner to achieve US12OF’s investment objective.





The
failure or bankruptcy of a clearing broker could result in a substantial loss of
US12OF’s assets; the clearing broker could be subject to proceedings that impair
its ability to execute US12OF’s trades.





Under
CFTC regulations, a clearing broker maintains customers’ assets in a bulk
segregated account. If a clearing broker fails to do so, or is unable to satisfy
a substantial deficit in a customer account, its other customers may be subject
to risk of a substantial loss of their funds in the event of that clearing
broker’s bankruptcy. In that event, the clearing broker’s customers, such as
US12OF, are entitled to recover, even in respect of property specifically
traceable to them, only a proportional share of all property available for
distribution to all of that clearing broker’s customers. The bankruptcy of a
clearing broker could result in the complete loss of US12OF’s assets posted with
the clearing broker; though the vast majority of US12OF’s assets are held in
Treasuries, cash and/or cash equivalents with US12OF’s custodian and would not
be impacted by the bankruptcy of a clearing broker. US12OF also may be subject
to the risk of the failure of, or delay in performance by, any exchanges and
markets and their clearing organizations, if any, on which commodity interest
contracts are traded.




64




From time
to time, the clearing brokers may be subject to legal or regulatory proceedings
in the ordinary course of their business. A clearing broker’s involvement in
costly or time-consuming legal proceedings may divert financial resources or
personnel away from the clearing broker’s trading operations, which could impair
the clearing broker’s ability to successfully execute and clear US12OF’s
trades.




The
failure or insolvency of US12OF’s custodian could result in a substantial loss
of US12OF’s assets.




As noted
above, the vast majority of US12OF’s assets are held in Treasuries, cash and/or
cash equivalents with US12OF’s custodian. The insolvency of the custodian could
result in a complete loss of US12OF’s assets held by that custodian, which, at
any given time, would likely comprise a substantial portion of US12OF’s total
assets.





Third
parties may infringe upon or otherwise violate intellectual property rights or
assert that the General Partner has infringed or otherwise violated their
intellectual property rights, which may result in significant costs and diverted
attention.





Third
parties may utilize US12OF’s intellectual property or technology, including the
use of its business methods, trademarks and trading program software, without
permission. The General Partner has a patent pending for US12OF’s business
method and it is registering its trademarks. US12OF does not currently have any
proprietary software. However, if it obtains proprietary software in the future,
then any unauthorized use of US12OF’s proprietary software and other technology
could also adversely affect its competitive advantage. US12OF may have
difficulty monitoring unauthorized uses of its patents, trademarks, proprietary
software and other technology. Also, third parties may independently develop
business methods, trademarks or proprietary software and other technology
similar to that of the General Partner or claim that the General Partner has
violated their intellectual property rights, including their copyrights,
trademark rights, trade names, trade secrets and patent rights. As a result, the
General Partner may have to litigate in the future to protect its trade secrets,
determine the validity and scope of other parties’ proprietary rights, defend
itself against claims that it has infringed or otherwise violated other parties’
rights, or defend itself against claims that its rights are invalid. Any
litigation of this type, even if the General Partner is successful and
regardless of the merits, may result in significant costs, divert its resources
from US12OF, or require it to change its proprietary software and other
technology or enter into royalty or licensing agreements.





The
success of US12OF depends on the ability of the General Partner to accurately
implement trading systems, and any failure to do so could subject US12OF to
losses on such transactions.





The
General Partner uses mathematical formulas built into a generally available
spreadsheet program to decide whether it should buy or sell Crude Oil Interests
each day. Specifically, the General Partner uses the spreadsheet to make
mathematical calculations and to monitor positions in Crude Oil Interests and
Treasuries and correlations to the Benchmark Futures Contracts. The General
Partner must accurately process the spreadsheets’ outputs and execute the
transactions called for by the formulas. In addition, US12OF relies on the
General Partner to properly operate and maintain its computer and communications
systems. Execution of the formulas and operation of the
systems are subject to human error. Any failure, inaccuracy or delay in
implementing any of the formulas or systems and executing US12OF’s transactions
could impair its ability to achieve US12OF’s investment objective. It could also
result in decisions to undertake transactions based on inaccurate or incomplete
information. This could cause substantial losses on
transactions.





US12OF
may experience substantial losses on transactions if the computer or
communications system fails.





US12OF’s
trading activities, including its risk management, depend on the integrity and
performance of the computer and communications systems supporting them.
Extraordinary transaction volume, hardware or software failure, power or
telecommunications failure, a natural disaster or other catastrophe could cause
the computer systems to operate at an unacceptably slow speed or even fail. Any
significant degradation or failure of the systems that the General Partner uses
to gather and analyze information, enter orders, process data, monitor risk
levels and otherwise engage in trading activities may result in substantial
losses on transactions, liability to other parties, lost profit opportunities,
damages to the General Partner’s and US12OF’s reputations, increased operational
expenses and diversion of technical resources.




65





If
the computer and communications systems are not upgraded, US12OF’s financial
condition could be harmed.





The
development of complex computer and communications systems and new technologies
may render the existing computer and communications systems supporting US12OF’s
trading activities obsolete. In addition, these computer and communications
systems must be compatible with those of third parties, such as the systems of
exchanges, clearing brokers and the executing brokers. As a result, if these
third parties upgrade their systems, the General Partner will need to make
corresponding upgrades to continue effectively its trading activities. US12OF’s
future success will depend on US12OF’s ability to respond to changing
technologies on a timely and cost-effective basis.





US12OF
depends on the reliable performance of the computer and communications systems
of third parties, such as brokers and futures exchanges, and may experience
substantial losses on transactions if they fail.





US12OF
depends on the proper and timely function of complex computer and communications
systems maintained and operated by the futures exchanges, brokers and other data
providers that the General Partner uses to conduct trading activities. Failure
or inadequate performance of any of these systems could adversely affect the
General Partner’s ability to complete transactions, including its ability to
close out positions, and result in lost profit opportunities and significant
losses on commodity interest transactions. This could have a material adverse
effect on revenues and materially reduce US12OF’s available capital. For
example, unavailability of price quotations from third parties may make it
difficult or impossible for the General Partner to use its proprietary software
that it relies upon to conduct its trading activities. Unavailability of records
from brokerage firms may make it difficult or impossible for the General Partner
to accurately determine which transactions have been executed or the details,
including price and time, of any transaction executed. This unavailability of
information also may make it difficult or impossible for the General Partner to
reconcile its records of transactions with those of another party or to
accomplish settlement of executed transactions.





The
occurrence of a terrorist attack, or the outbreak, continuation or expansion of
war or other hostilities could disrupt US12OF’s trading activity and materially
affect US12OF’s profitability.





The
operations of US12OF, the exchanges, brokers and counterparties with which
US12OF does business, and the markets in which US12OF does business could be
severely disrupted in the event of a major terrorist attack or the outbreak,
continuation or expansion of war or other hostilities. The terrorist attacks of
September 11, 2001 and the war in Iraq, global anti-terrorism initiatives and
political unrest in the Middle East and Southeast Asia continue to fuel this
concern.





Risk
of Leverage and Volatility





If
the General Partner permits US12OF to become leveraged, investors could lose all
or substantially all of their investment if US12OF’s trading positions suddenly
turn unprofitable.





Commodity
pools’ trading positions in futures contracts or other commodity interests are
typically required to be secured by the deposit of margin funds that represent
only a small percentage of a futures contract’s (or other commodity interests’)
entire market value. This feature permits commodity pools to “leverage” their
assets by purchasing or selling futures contracts (or other commodity interests)
with an aggregate value in excess of the commodity pool’s assets. While this
leverage can increase the pool’s profits, relatively small adverse movements in
the price of the pool’s futures contracts can cause significant losses to the
pool. While the General Partner has not and does not currently intend to
leverage US12OF’s assets, it is not prohibited from doing so under the LP
Agreement or otherwise.





The
price of crude oil is volatile which could cause large fluctuations in the price
of units.





Movements
in the price of crude oil may be the result of factors outside of the General
Partner’s control and may not be anticipated by the General Partner. Among the
factors that can cause volatility in the price of crude oil are:




·
            worldwide
      or regional demand for energy, which is affected by economic
      conditions;





66




·
            the
      domestic and foreign supply and inventories of oil and
  gas;





·
            weather
      conditions, including abnormally mild winter or summer weather, and
      abnormally harsh winter or summer
weather;





·
            availability
      and adequacy of pipeline and other transportation
    facilities;





·
            domestic
      and foreign governmental regulations and
taxes;





·
            political
      conditions in gas or oil producing
regions;





·
            technological
      advances relating to energy usage or relating to technology for
      exploration, production, refining and petrochemical
      manufacturing;





·
            the
      ability of members of OPEC to agree upon and maintain oil prices and
      production levels;





·
            the
      price and availability of alternative fuels;
and





·
            the
      impact of energy conservation
efforts.





The
impact of environmental and other governmental laws and regulations may affect
the price of crude oil.





Environmental
and other governmental laws and regulations have increased the costs to plan,
design, drill, install, operate and abandon oil wells. Other laws have prevented
exploration and drilling of crude oil in certain environmentally sensitive
federal lands and waters. Several environmental laws that have a direct or an
indirect impact on the price of crude oil include, but are not limited to, the
Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, and the
Comprehensive Environmental Response, Compensation and Liability Act of
1980.





The
limited method for transporting and storing crude oil may cause the price of
crude oil to increase.





Crude oil
is transported throughout the United States by way of pipelines, barges,
tankers, trucks and rail cars and is stored in aboveground and underground
storage facilities. These systems may not be adequate to meet demand, especially
in times of peak demand or in areas of the United States where crude oil service
is already limited due to minimal pipeline and storage infrastructure. As a
result of the limited method for transporting and storing crude oil, the price
of crude oil may increase.





Over-the-Counter
Contract Risk





Over-the-counter
transactions are subject to little, if any, regulation.





A portion
of US12OF’s assets may be used to trade over-the-counter crude oil interest
contracts, such as forward contracts or swap or spot contracts. Over-the-counter
contracts are typically traded on a principal-to-principal basis through dealer
markets that are dominated by major money center and investment banks and other
institutions and are essentially unregulated by the CFTC. Investors therefore do
not receive the protection of CFTC regulation or the statutory scheme of the CEA
in connection with this trading activity by US12OF. The markets for
over-the-counter contracts rely upon the integrity of market participants in
lieu of the additional regulation imposed by the CFTC on participants in the
futures markets. The lack of regulation in these markets could expose US12OF in
certain circumstances to significant losses in the event of trading abuses or
financial failure by participants.





US12OF
will be subject to credit risk with respect to counterparties to
over-the-counter contracts entered into by US12OF or held by special purpose or
structured vehicles.





US12OF
also faces the risk of non-performance by the counterparties to the
over-the-counter contracts. Unlike in futures contracts, the counterparty to
these contracts is generally a single bank or other financial institution,
rather than a clearing organization backed by a group of financial institutions.
As a result, there will be greater counterparty credit risk in these
transactions. A counterparty may not be able to meet its obligations to US12OF,
in which case US12OF could suffer significant losses on these
contracts.




67





If a
counterparty becomes bankrupt or otherwise fails to perform its obligations due
to financial difficulties, US12OF may experience significant delays in obtaining
any recovery in a bankruptcy or other reorganization proceeding. US12OF may
obtain only limited recovery or may obtain no recovery in such
circumstances.





US12OF
may be subject to liquidity risk with respect to its over-the-counter
contracts.





Over-the-counter
contracts may have terms that make them less marketable than Futures Contracts.
Over-the-counter contracts are less marketable because they are not traded on an
exchange, do not have uniform terms and conditions, and are entered into based
upon the creditworthiness of the parties and the availability of credit support,
such as collateral, and in general, they are not transferable without the
consent of the counterparty. These conditions diminish the ability to realize
the full value of such contracts.  In addition, even if collateral is
used to reduce counterparty credit risk, sudden changes in the value of
over-the-counter transactions may leave a party open to financial risk due to a
counterparty default since the collateral held may not cover a party’s exposure
on the transaction in such situations.





Risk
of Trading in International Markets





Trading
in international markets could expose US12OF to credit and regulatory
risk.





The
General Partner invests primarily in Futures Contracts, a significant portion of
which are traded on United States exchanges, including the NYMEX. However, a
portion of US12OF’s trades may take place on markets and exchanges outside the
United States. Some non-U.S. markets present risks because they are not subject
to the same degree of regulation as their U.S. counterparts. None of the CFTC,
NFA, or any domestic exchange regulates activities of any foreign boards of
trade or exchanges, including the execution, delivery and clearing of
transactions, nor has the power to compel enforcement of the rules of a foreign
board of trade or exchange or of any applicable non-U.S. laws. Similarly, the
rights of market participants, such as US12OF, in the event of the insolvency or
bankruptcy of a non-U.S. market or broker are also likely to be more limited
than in the case of U.S. markets or brokers. As a result, in these markets,
US12OF has less legal and regulatory protection than it does when it trades
domestically.





In some
of these non-U.S. markets, the performance on a contract is the responsibility
of the counterparty and is not backed by an exchange or clearing corporation and
therefore exposes US12OF to credit risk. Trading in non-U.S. markets also leaves
US12OF susceptible to swings in the value of the local currency against the U.S.
dollar. Additionally, trading on non-U.S. exchanges is subject to the risks
presented by exchange controls, expropriation, increased tax burdens and
exposure to local economic declines and political instability. An adverse
development with respect to any of these variables could reduce the profit or
increase the loss earned on trades in the affected international
markets.





International
trading activities subject US12OF to foreign exchange risk.





The price
of any non-U.S. Futures Contract, option on any non-U.S. Futures Contract, or
other non-U.S. Crude Oil Interest and, therefore, the potential profit and loss
on such contract, may be affected by any variance in the foreign exchange rate
between the time the order is placed and the time it is liquidated, offset or
exercised. As a result, changes in the value of the local currency relative to
the U.S. dollar may cause losses to US12OF even if the contract traded is
profitable.





US12OF’s
international trading could expose it to losses resulting from non-U.S.
exchanges that are less developed or less reliable than United States
exchanges.





Some
non-U.S. exchanges may be in a more developmental stage so that prior price
histories may not be indicative of current price dynamics. In addition, US12OF
may not have the same access to certain positions on foreign trading exchanges
as do local traders, and the historical market data on which the General Partner
bases its strategies may not be as reliable or accessible as it is for U.S.
exchanges.




68





Tax
Risk





An
investor’s tax liability may exceed the amount of distributions, if any, on
its units.





Cash or
property will be distributed at the sole discretion of the General Partner. The
General Partner has not and does not currently intend to make cash or other
distributions with respect to units. Investors will be required to pay U.S.
federal income tax and, in some cases, state, local, or foreign income tax, on
their allocable share of US12OF’s taxable income, without regard to whether they
receive distributions or the amount of any distributions. Therefore, the tax
liability of an investor with respect to its units may exceed the amount of cash
or value of property (if any) distributed.





An
investor’s allocable share of taxable income or loss may differ from its
economic income or loss on its units.





Due to
the application of the assumptions and conventions applied by US12OF in making
allocations for tax purposes and other factors, an investor’s allocable share of
US12OF’s income, gain, deduction or loss may be different than its economic
profit or loss from its units for a taxable year. This difference could be
temporary or permanent and, if permanent, could result in it being taxed on
amounts in excess of its economic income.





Items
of income, gain, deduction, loss and credit with respect to units could be
reallocated if the IRS does not accept the assumptions and conventions applied
by US12OF in allocating those items, with potential adverse consequences for an
investor.





The U.S.
tax rules pertaining to partnerships are complex and their application to large,
publicly traded partnerships such as US12OF is in many respects uncertain.
US12OF applies certain assumptions and conventions in an attempt to comply with
the intent of the applicable rules and to report taxable income, gains,
deductions, losses and credits in a manner that properly reflects unitholders’
economic gains and losses. These assumptions and conventions may not fully
comply with all aspects of the Internal Revenue Code (the “Code”) and applicable
Treasury Regulations, however, and it is possible that the U.S. Internal Revenue
Service will successfully challenge US12OF’s allocation methods and require
US12OF to reallocate items of income, gain, deduction, loss or credit in a
manner that adversely affects investors. If this occurs, investors may be
required to file an amended tax return and to pay additional taxes plus
deficiency interest.





US12OF
could be treated as a corporation for federal income tax purposes, which may
substantially reduce the value of the units.





US12OF
has received an opinion of counsel that, under current U.S. federal income tax
laws, US12OF will be treated as a partnership that is not taxable as a
corporation for U.S. federal income tax purposes, provided that (i) at least 90
percent of US12OF’s annual gross income consists of “qualifying income” as
defined in the Code, (ii) US12OF is organized and operated in accordance with
its governing agreements and applicable law and (iii) US12OF does not elect to
be taxed as a corporation for federal income tax purposes. Although the General
Partner anticipates that US12OF has satisfied and will continue to satisfy the
“qualifying income” requirement for all of its taxable years, that result cannot
be assured. US12OF has not requested and will not request any ruling from the
IRS with respect to its classification as a partnership not taxable as a
corporation for federal income tax purposes. If the IRS were to successfully
assert that US12OF is taxable as a corporation for federal income tax purposes
in any taxable year, rather than passing through its income, gains, losses and
deductions proportionately to unitholders, US12OF would be subject to tax on its
net income for the year at corporate tax rates. In addition, although the
General Partner does not currently intend to make distributions with respect to
units, any distributions would be taxable to unitholders as dividend income.
Taxation of US12OF as a corporation could materially reduce the after-tax return
on an investment in units and could substantially reduce the value of the
units.

Introduction





US12OF, a
Delaware limited partnership, is a commodity pool that issues units that may be
purchased and sold on the NYSE Arca. The investment objective of US12OF is for
the changes in percentage terms of its units’ NAV  to reflect the
changes in percentage terms of the spot price of light, sweet crude oil
delivered to Cushing, Oklahoma, as measured by the changes in the average of the
prices of 12 Futures Contracts for crude oil traded on the NYMEX consisting of
the near month contract to expire and the contracts for the following 11 months
for a total of 12 consecutive months’ contracts, except when the near month
contract is within two weeks of expiration, in which case it will be measured by
the futures contracts that is the next month contract to expire and the
contracts for the following 11 consecutive months, less US12OF’s
expenses.





US12OF
seeks to achieve its investment objective by investing in a combination of
Futures Contracts and Other Crude Oil-Related Investments such that changes in
its NAV, measured in percentage terms, will closely track the changes in
the average of the prices of the Benchmark Futures Contracts, also measured
in percentage terms. US12OF’s General Partner believes the Benchmark Futures
Contracts historically have exhibited a close correlation with the spot
price of light, sweet crude oil. It is not the intent of US12OF to be operated
in a fashion such that the NAV will equal, in dollar terms, the spot price of
light, sweet crude oil or any particular futures contract based on light, sweet
crude oil. Management believes that it is not practical to manage the portfolio
to achieve such an investment goal when investing in listed crude oil Futures
Contracts and Crude Oil Interests.

On any valuation day, the Benchmark Futures Contracts are the
near month futures contract for light, sweet crude oil traded on the NYMEX
and the contracts for the following 11 months for a total of 12 consecutive
months’ contracts unless the near month contract is within two weeks of
expiration in which case the Benchmark Futures Contracts are the next month
contract for light, sweet crude oil traded on the NYMEX and the contracts for
the following 11 consecutive months. “Near month contract” means the next
contract traded on the NYMEX due to expire. “Next month contract” means the
first contract traded on the NYMEX due to expire after the near month
contract.





The
regulation of Crude Oil Interests in the United States is a rapidly changing
area of law and is subject to ongoing modification by governmental and judicial
action.  As stated under the heading, “Risk Factors” in Item 1A of
this annual report on Form 10-K, regulation of the commodity interests and
energy markets is extensive and constantly changing; future regulatory
developments in the commodity interests and energy markets are impossible to
predict but may significantly and adversely affect US12OF.





Currently,
a number of proposals to alter the regulation of oil interests are being
considered by federal regulators and legislators. These proposals include the
imposition of hard position limits on energy-based commodity futures contracts,
the extension of position and accountability limits to futures contracts on
non-U.S. exchanges previously exempt from such limits, and the forced use of
clearinghouse mechanisms for all over-the-counter transactions. An additional
proposal would aggregate and limit all positions in energy futures held by a
single entity, whether such positions exist on U.S. futures exchanges, non-U.S.
futures exchanges, or in over-the-counter contracts. The CFTC has also recently
published a proposed rule that would impose fixed position limits on certain
energy futures contracts without the need for any new legislation to be passed.
If any of the aforementioned proposals is implemented, US12OF’s ability to meet
its investment objective may be negatively impacted and investors could be
adversely affected.





US12OF
may also invest in Futures Contracts and Other Crude Oil-Related
Investments. The General Partner of US12OF, which is registered as a CPO with
the CFTC, is authorized by the LP Agreement to manage US12OF. The General
Partner is authorized by US12OF in its sole judgment to employ and establish the
terms of employment for, and termination of, commodity trading advisors or
futures commission merchants.





Average
crude oil futures prices were volatile during 2009 and exhibited wide daily
swings along with an uneven upward trend from late February 2009 to late March
2009. The average price of the Benchmark Futures Contracts started the year at
$54.01 per barrel. The low of the year was on February 18, 2009 when prices
reached $44.24 per barrel. The average price of the Benchmark Futures
Contracts rose over the course of the year and hit a peak on October 21,
2009 of $83.85 per barrel. The year ended with the average price of the
Benchmark Futures Contracts at $82.15 per barrel, up approximately 52.10% over
the year. Similarly, US12OF’s NAV rose during the year from a starting level of
$31.24 per unit to a high on October 21, 2009 of $41.99 per unit. US12OF’s NAV
reached its low for the year on February 18, 2009 at $24.34 per unit. The NAV on
December 31, 2009 was $40.37, up approximately 29.23% over the
year.





During
parts of January and February 2009, the level of contango remained unusually
steep, meaning that the price of the near month crude oil futures
contract was less than the price of the next month crude oil futures
contract, or contracts further away from expiration. Crude oil inventories,
which reached unusually high levels in January 2009 and February 2009
and which appeared to be the primary cause of the steep level of contango, began
to drop in March 2009 and for the balance of the first half of 2009. The crude
oil futures market remained in contango through the rest of  2009. For
a discussion of the impact of backwardation and contango on total returns, see
“Term Structure of Crude Oil Prices and the Impact on Total
Returns”.





Valuation
of Futures Contracts and the Computation of the NAV





The NAV
of US12OF’s units is calculated once each NYSE Arca trading day. The NAV for a
particular trading day is released after 4:00 p.m. New York time. Trading
during the core trading session on the NYSE Arca typically closes at
4:00 p.m. New York time.   The Administrator uses the NYMEX
closing price (determined at the earlier of the close of the NYMEX or
2:30 p.m. New York time) for the contracts held on the NYMEX, but
calculates or determines the value of all other US12OF investments, including
ICE Futures contracts or other futures contracts, as of the earlier of
the close of the NYSE Arca or 4:00 p.m. New York time.

Results
of Operations and the Crude Oil Market





Results of
Operations. On December 6, 2007, US12OF listed its units on the AMEX
under the ticker symbol “USL.” On that day, US12OF established its initial
offering price at $50.00 per unit and issued 300,000 units to the initial
Authorized Purchaser, Merrill Lynch Professional Clearing Corp., in exchange for
$15,001,000 in cash. As a result of the acquisition of the AMEX by NYSE
Euronext, US12OF’s units no longer trade on the AMEX and commenced trading on
the NYSE Arca on November 25, 2008.





Since its
initial offering of 11,000,000 units, US12OF has made one subsequent offering of
its units: 100,000,000 units which were registered with the SEC on March
31, 2009. As of December 31, 2009, US12OF had issued 7,500,000 units, 4,100,000
of which were outstanding.  As of December 31, 2009, there were
103,500,000 units registered but not yet issued.





More
units may have been issued by US12OF than are outstanding due to the redemption
of units.  Unlike funds that are registered under the 1940 Act,
units that have been redeemed by US12OF cannot be resold by US12OF. As a result,
US12OF contemplates that additional offerings of its units will be
registered with the SEC in the future in anticipation of additional
issuances and redemptions.





For the Year Ended December
31, 2009 Compared to the Year Ended December 31, 2008 and the Period from June
27, 2007 (inception) to December 31, 2007





As of
December 31, 2009, the total unrealized gain on Futures Contracts owned or
held on that day was $20,802,090 and US12OF established cash deposits,
including cash investments in money market funds, that were equal to
$145,075,490. US12OF held 97.65% of its cash assets in overnight deposits and
money market funds at the Custodian, while 2.35% of the cash balance was held as
margin deposits for the Futures Contracts purchased. The ending per unit NAV on
December 31, 2009 was $40.37.





By
comparison, as of December 31, 2008, the total unrealized loss on Futures
Contracts owned or held on that day was $2,754,630 and US12OF established
cash deposits, including cash investments in money market funds, that were equal
to $9,005,535. US12OF held 44.55% of its cash assets in overnight deposits and
money market funds at the Custodian, while 55.45% of the cash balance was held
as margin deposits for the Futures Contracts purchased. The ending per unit NAV
on December 31, 2008 was $31.24.  The increase in the per unit NAV
from December 31, 2008 to December 31, 2009 was primarily a result of higher
prices for crude oil and the related increase in the value of the Futures
Contracts that US12OF had invested in between the year ended December 31, 2008
and the year ended December 31, 2009.





By
comparison, as of December 31, 2007, the total unrealized gain on Futures
Contracts owned or held on that day was $1,525,370 and US12OF established
cash deposits, including cash investments in money market funds, that were equal
to $20,173,384. US12OF held 90.09% of its cash assets in overnight deposits and
money market funds at the Custodian, while 9.91% of the cash balance was held as
margin deposits for the Futures Contracts purchased. The ending per unit NAV on
December 31, 2007 was $54.23.  The decrease in the per unit NAV from
December 31, 2007 to December 31, 2008 was primarily a result of sharply lower
prices for crude oil and the related decline in the value of the Futures
Contracts that US12OF had invested in between the period ended December 31, 2007
and the year ended December 31, 2008.  Relatively higher prices in
2007 were due to increased demand for crude oil that decreased in 2008 due to
the economic downturn, which led to decreased demand for oil.





Portfolio Expenses. US12OF’s
expenses consist of investment management fees, brokerage
fees and commissions, certain offering costs, licensing fees, the fees and
expenses of the independent directors of the General Partner and expenses
relating to tax accounting and reporting requirements.  The management
fee that US12OF pays to the General Partner is calculated as a percentage of the
total net assets of US12OF.  US12OF pays the General Partner a
management fee of 0.60% of its average net assets. The fee is accrued
daily.


73





During
the year ended December 31, 2009, the daily average total net assets of US12OF
were $144,092,781. The management fee paid by US12OF during the period
amounted to $864,557.





By
comparison, during the year ended December 31, 2008, the daily average total net
assets of US12OF were $8,197,841. The management fee paid by US12OF
during the period amounted to $49,187, which was calculated at the 0.60% rate
and accrued daily.





By
comparison, during the period from June 27, 2007 to December 31, 2007, the daily
average total net assets of US12OF were $20,566,413. The management fee
paid by US12OF amounted to $8,790, which was calculated at the 0.60% rate and
accrued daily.





In
addition to the management fee, US12OF pays all brokerage fees and other
expenses, including certain tax reporting costs, licensing fees for the use of
intellectual property, ongoing registration or other fees paid to the
SEC, FINRA and any other regulatory agency in connection
with offers and sales of its units subsequent to the initial offering and
all legal, accounting, printing and other expenses associated therewith. The
total of these fees and expenses for the year ended December 31, 2009 was
$718,091, as compared to $20,859 for the year ended December 31, 2008 and $4,371
for the period from June 27, 2007 through December 31, 2007. The increase in
expenses during the year ended December 31, 2009 was primarily due to the
relative size of US12OF and activity that resulted from its increased size,
including the registration and the offering of additional units, increased
brokerage fees, increased licensing fees and increased tax reporting costs due
to the greater number of unitholders during each year. For the year ended
December 31, 2009, US12OF incurred $107,883 in ongoing registration fees
and other expenses relating to the registration and offering of additional
units. By comparison, for the year ended December 31, 2008 and the period from
June 27, 2007 through December 31, 2007, US12OF did not incur any ongoing
registration fees or other expenses relating to the registration and offering of
additional units.





US12OF is
responsible for paying its portion of the directors’ and officers’ liability
insurance of the General Partner and the fees and expenses of the independent
directors of the General Partner who are also the General Partner’s audit
committee members. US12OF shares these fees and expenses with the
Related Public Funds based on the relative assets of each fund computed on a
daily basis. These fees and expenses for calendar year 2009 amounted to a total
of $433,046 for all funds, and US12OF’s portion of such fees and expenses was
$12,326.





By comparison, for the
year ended December 31, 2008, these fees and expenses amounted to a total of
$282,000 for all funds, and US12OF’s portion of such fees and expenses was
$1,762. The increase in directors’ expenses incurred by US12OF from the year
ended December 31, 2008 compared to the year ended December 31, 2009 was
primarily due topayment for directors’ and officers’ liability
insurance, an increase in the compensation awarded to the independent directors
of the General Partner and the proportionate sharing of these fees and expenses
with the Related Public Funds. Effective as of March 3, 2009, the General
Partner obtained directors’ and officers’ liability insurance covering all of
the directors and officers of the General Partner. Previously, the General
Partner did not have liability insurance for its directors and officers;
instead, the independent directors received a payment in lieu of directors’ and
officers’ liability insurance coverage.





By
comparison, for the period from June 27, 2007 through December 31, 2007, these
fees and expenses amounted to a total of $286,000 for all funds, and US12OF’s
portion of such fees and expenses was $350.  The increase in
directors’ expenses incurred by US12OF from the period from June 27, 2007
through December 31, 2007 compared to the year ended December 31, 2008 was due
to the proportionate sharing of these fees and expenses with the Related Public
Funds.





US12OF
also incurs commissions to brokers for the purchase and sale of Futures
Contracts, Other Crude Oil-Related Investments or Treasuries. During the
year ended December 31, 2009, total commissions paid to brokers amounted to
$49,573. By comparison, during the year ended December 31, 2008 and the period
from June 27, 2007 through December 31, 2007, total commissions paid to brokers
amounted to $2,325 and $892, respectively. The increase in the total commissions
paid to brokers was primarily a function of increased brokerage fees due to a
higher number of futures contracts being held and traded as a result of the
increase in US12OF’s average total net assets, the decrease in the price of
Futures Contracts and the increase in redemptions and creations of units during
each year. The increase in assets required US12OF to purchase a greater number
of Futures Contracts and incur a larger amount of commissions. As an annualized
percentage of total net assets, the figure for the year ended December 31,
2009 represents approximately 0.03% of total net assets. By comparison, the
figure for the year ended December 31, 2008 represented approximately 0.03% of
total net assets and the figure for the period from June 27, 2007 through
December 31, 2007 represented approximately 0.06% of total net assets. However,
there can be no assurance that commission costs and portfolio turnover will not
cause commission expenses to rise in future quarters.


74





The fees
and expenses associated with US12OF’s audit expenses and tax accounting and
reporting requirements are paid by US12OF. These costs are estimated to be
$315,000 for the year ended December 31, 2009.





Interest Income. US12OF seeks
to invest its assets such that it holds Futures Contracts and Other Crude
Oil-Related Investments in an amount equal to the total net assets of its
portfolio. Typically, such investments do not require US12OF to pay the full
amount of the contract value at the time of purchase, but rather require US12OF
to post an amount as a margin deposit against the eventual settlement of the
contract. As a result, US12OF retains an amount that is approximately equal to
its total net assets, which US12OF invests in Treasuries, cash and/or cash
equivalents. This includes both the amount on deposit with the futures
commission merchant as margin, as well as unrestricted cash and cash equivalents
held with US12OF’s Custodian. The Treasuries, cash and/or cash equivalents earn
interest that accrues on a daily basis. For the year ended December 31, 2009,
US12OF earned $195,614 in interest income on such cash holdings. Based on
US12OF’s average daily total net assets, this was equivalent to an annualized
yield of 0.14%. US12OF did not purchase Treasuries during the year ended
December 31, 2009 and held all of its funds in cash and/or cash equivalents
during this time period. By comparison, for the year ended December 31, 2008 and
the period from June 27, 2007 through December 31, 2007, US12OF earned $151,396
and $49,954, respectively, in interest income on such cash holdings. Based on
US12OF’s average daily total net assets, this was equivalent to an annualized
yield of 1.85% and 3.41%, respectively.  US12OF did not
purchase Treasuries during the year ended December 31, 2008 or the period
from June 27, 2007 through December 31, 2007 and held all of its funds in cash
and/or cash equivalents during these time periods. Interest rates on short-term
investments in the United States, including cash, cash equivalents, and
short-term Treasuries, were sharply lower during the year ended December 31,
2009 compared to the year ended December 31, 2008 and the period from June 27,
2007 through December 31, 2007. As a result, the amount of interest earned by
US12OF as a percentage of total net assets was lower during the year ended
December 31, 2009 compared to the year ended December 31, 2008 and the period
from June 27, 2007 through December 31, 2007.





For the Three Months Ended
December 31, 2009 Compared to the Three Months Ended December 31, 2008 and
2007





Portfolio
Expenses.  During the three months ended December 31, 2009, the
daily average total net assets of US12OF were $160,027,587. The management
fee paid by US12OF during the period amounted to $242,015. Management fees as a
percentage of total net assets averaged 0.60% over the three months ended
December 31, 2009.





By
comparison, during the three months ended December 31, 2008, the daily average
total net assets of US12OF were $4,256,374. The management fee paid by
US12OF during the period amounted to $6,419. Management expenses as a percentage
of total net assets averaged 0.60% over the course of the period.





By
comparison, during the three months ended December 31, 2007, the daily average
total net assets of US12OF were $20,566,413. The management fee paid by
US12OF during the period amounted to $8,790. Management expenses as a percentage
of total net assets averaged 0.60% over the course of the period.





In
addition to the management fee, US12OF pays all brokerage fees and other
expenses, including certain tax reporting costs, licensing fees for the use of
intellectual property, ongoing registration or other fees paid to the
SEC, FINRA and any other regulatory agency in connection
with offers and sales of its units subsequent to the initial offering and
all legal, accounting, printing and other expenses associated therewith. The
total of these fees and expenses for the three months ended December 31, 2009
was $271,997, as compared to $2,843 for the three months ended December 31, 2008
and $8,790 for the three months ended December 31, 2007. The increase in
expenses during the three months ended December 31, 2008 and 2009 was primarily
due to the relative size of US12OF and activity that resulted from its increased
size, including the registration and the offering of additional units, increased
brokerage fees, increased licensing fees and increased tax reporting costs due
to the greater number of unitholders during each year. For the three months
ended December 31, 2009, US12OF incurred $11,633 in ongoing registration
fees and other expenses relating to the registration and offering of additional
units. By comparison, for the three months ended December 31, 2008 the three
months ended December 31, 2007, US12OF did not incur any ongoing registration
fees or other expenses relating to the registration and offering of additional
units.


75





US12OF is
responsible for paying its portion of the directors’ and officers’ liability
insurance of the General Partner and the fees and expenses of the independent
directors of the General Partner who are also the General Partner’s audit
committee members. US12OF shares these fees and expenses with the
Related Public Funds based on the relative assets of each fund computed on a
daily basis. These fees and expenses for the three months ended December 31,
2009 amounted to a total of $119,250 for all funds, and US12OF’s portion of such
fees and expenses was $1,995.





By comparison, for the
three months ended December 31, 2008, these fees and expenses amounted to a
total of $68,750 for all funds, and US12OF’s portion of such fees and expenses
was $155.  The increase in directors’ expenses incurred by US12OF from
the three months ended December 31, 2008 to the three months ended December 31,
2009 was primarily due topayment for directors’ and officers’ liability
insurance, an increase in the compensation awarded to the independent directors
of the General Partner and the proportionate sharing of these fees and expenses
with the Related Public Funds. Effective as of March 3, 2009, the General
Partner obtained directors’ and officers’ liability insurance covering all of
the directors and officers of the General Partner. Previously, the General
Partner did not have liability insurance for its directors and officers;
instead, the independent directors received a payment in lieu of directors’ and
officers’ liability insurance coverage.





By
comparison, for the three months ended December 31, 2007, these fees and
expenses amounted to a total of $41,379 for all funds, and US12OF’s portion of
such fees and expenses was $339.  The increase in directors’ expenses
incurred by US12OF from the three months ended December 31, 2007 to the three
months ended December 31, 2008 was due to the proportionate sharing of these
fees and expenses with the Related Public Funds and the longer reporting
period.





US12OF
also incurs commissions to brokers for the purchase and sale of Futures
Contracts, Other
Crude Oil-Related Investmentsor Treasuries. During the three months
ended December 31, 2009, total commissions paid to brokers amounted to $5,043.
By comparison, during the three months ended December 31, 2008 and the three
months ended December 31, 2007, total commissions paid to brokers amounted to
$757 and $892, respectively. The increase in the total commissions paid to
brokers for the three months ended December 31, 2009 was primarily a function of
increased brokerage fees due to a higher number of futures contracts being held
and traded as a result of the increase in US12OF’s average total net assets, the
decrease in the price of Futures Contracts and the increase in redemptions and
creations of units during each period. The increase in assets required US12OF to
purchase a greater number of Futures Contracts and incur a larger amount of
commissions. As an annualized percentage of total net assets, the figure
for the three months ended December 31, 2009 represents approximately 0.01% of
total net assets. By comparison, the figure for the three months ended December
31, 2008 represented approximately 0.07% of total net assets and the figure for
the three months ended December 31, 2007 represented approximately 0.06% of
total net assets. However, there can be no assurance that commission costs and
portfolio turnover will not cause commission expenses to rise in future
quarters.





The fees
and expenses associated with US12OF’s audit expenses and tax accounting and
reporting requirements are paid by US12OF. No amounts were required to be
paid for audit expenses and tax accounting and reporting requirements for the
three months ended December 31, 2009.





Interest Income. US12OF seeks
to invest its assets such that it holds Futures Contracts and Other Crude
Oil-Related Investments in an amount equal to the total net assets of its
portfolio. Typically, such investments do not require US12OF to pay the full
amount of the contract value at the time of purchase, but rather require US12OF
to post an amount as a margin deposit against the eventual settlement of the
contract. As a result, US12OF retains an amount that is approximately equal to
its total net assets, which US12OF invests in Treasuries, cash and/or cash
equivalents. This includes both the amount on deposit with the futures
commission merchant as margin, as well as unrestricted cash and cash equivalents
held with US12OF’s Custodian. The Treasuries, cash and/or cash equivalents earn
interest that accrues on a daily basis. For the three months ended December 31,
2009, US12OF earned $21,318 in interest income on such cash holdings. Based on
US12OF’s average daily total net assets, this was equivalent to an annualized
yield of 0.05%. US12OF did not purchase Treasuries during the three months
ended December 31, 2009 and held all of its funds in cash and/or cash
equivalents during this time period. By comparison, for the three months ended
December 31, 2008 and 2007, US12OF earned $10,012 and $49,954, respectively, in
interest income on such cash holdings. Based on US12OF’s average daily total net
assets, this was equivalent to an annualized yield of 0.94% and 3.41%,
respectively.  US12OF did not purchase Treasuries during the
three months ended December 31, 2008 or 2007 and held all of its funds in cash
and/or cash equivalents during these time periods. Interest rates on short-term
investments in the United States, including cash, cash equivalents, and
short-term Treasuries, were sharply lower during the three months ended December
31, 2009 compared to the same time periods in 2008 and 2007. As a result, the
amount of interest earned by US12OF as a percentage of total net assets was
lower during the three months ended December 31, 2009 compared to the three
months ended December 31, 2008 and 2007.


76





Tracking US12OF’s Benchmark.
US12OF seeks to manage its portfolio such that changes in its average daily NAV,
on a percentage basis, closely track the changes in the average of the daily
prices of the Benchmark Futures Contracts, also on a percentage basis.
Specifically, US12OF seeks to manage the portfolio such that over any rolling
period of 30 valuation days, the average daily change in the NAV is within a
range of 90% to 110% (0.9 to 1.1) of the average daily change in the prices of
the Benchmark Futures Contracts. As an example, if the average daily
movement of the average of the prices of the Benchmark Futures
Contracts for a particular 30-day time period was 0.5% per day, US12OF
management would attempt to manage the portfolio such that the average daily
movement of the NAV during that same time period fell between 0.45% and 0.55%
(i.e., between 0.9 and
1.1 of the benchmark’s results). US12OF’s portfolio management goals do not
include trying to make the nominal price of US12OF’s NAV equal to the average of
the nominal prices of the current Benchmark Futures Contracts or the spot
price for light, sweet crude oil. Management believes that it is not practical
to manage the portfolio to achieve such an investment goal when investing in
listed crude oil Futures Contracts.





For the
30 valuation days ended December 31, 2009, the simple average daily change in
the Benchmark Futures Contracts was -0.057%, while the simple average daily
change in the NAV of US12OF over the same time period was -0.062%. The average
daily difference was -0.005% (or -0.5 basis points, where 1 basis point equals
1/100 of 1%). As a percentage of the daily movement of the Benchmark Futures
Contracts, the average error in daily tracking by the NAV was -0.582%, meaning
that over this time period US12OF’s tracking error was within the plus or minus
10% range established as its benchmark tracking goal. The first chart below
shows the daily movement of US12OF’s NAV versus the daily movement of the
Benchmark Futures Contracts for the 30-day period ended December 31,
2009.

Since the
offering of US12OF’s units to the public on June 27, 2007 to December 31,
2009, the simple average daily change in the Benchmark Futures Contracts was
-0.004%, while the simple average daily change in the NAV of US12OF over the
same time period was -0.003%. The average daily difference was 0.001% (or 0.1
basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the
daily movement of the Benchmark Futures Contracts, the average error in daily
tracking by the NAV was 0.107 %, meaning that over this time period US12OF’s
tracking error was within the plus or minus 10% range established as its
benchmark tracking goal.





An
alternative tracking measurement of the return performance of US12OF versus the
return of its Benchmark Futures Contracts can be calculated by comparing the
actual return of US12OF, measured by changes in its NAV, versus the expected changes in its NAV
under the assumption that US12OF’s returns had been exactly the same as the
daily changes in the average of the prices of its Benchmark Futures
Contracts.





For the
year ended December 31, 2009, the actual total return of US12OF as measured
by changes in its NAV was 29.23%. This is based on an initial NAV of $31.24
on December 31, 2008 and an ending NAV as of December 31, 2009 of $40.37.
During this time period, US12OF made no distributions to its unitholders.
However, if US12OF’s daily changes in its NAV had instead exactly tracked the
changes in the daily return of the Benchmark Oil Futures Contracts, US12OF would
have ended 2009 with an estimated NAV of $40.83, for a total return over the
relevant time period of 30.69%. The difference between the actual NAV total
return of US12OF of 29.23% and the expected total return based on the Benchmark
Futures Contracts of 30.69% was an error over the time period of -1.46%, which
is to say that US12OF’s actual total return trailed the benchmark result by that
percentage. Management believes that a portion of the difference between
the actual return and the expected benchmark return can be attributed to the net
impact of the expenses and the interest that US12OF collects on its cash and
cash equivalent holdings. During the year ended December 31, 2009, US12OF
received interest income of $195,614, which is equivalent to a weighted average
interest rate of 0.14% for 2009. In addition, during the year
ended December 31, 2009, US12OF also collected $32,000 from its Authorized
Purchasers creating or redeeming baskets of units. This income also contributed
to US12OF’s actual return. However, if the total assets of US12OF continue to
increase, management believes that the impact on total returns of these fees
from creations and redemptions will diminish as a percentage of the total
return. During the year ended December 31, 2009, US12OF incurred total net
expenses of $1,582,648. Income from interest and Authorized Purchaser
collections net of expenses was $(1,355,034) which is equivalent to a weighted
average net interest rate of -0.95% for the year ended December 31,
2009.





By
comparison, for the year ended December 31, 2008, the actual total return
of US12OF as measured by changes in its NAV was -42.39%. This is based on an
initial NAV of $54.23 on December 31, 2007 and an ending NAV as of
December 31, 2008 of $31.24. During this time period, US12OF made no
distributions to its unitholders. However, if US12OF’s daily changes in its NAV
had instead exactly tracked the changes in the daily return of the Benchmark
Futures Contracts, US12OF would have ended 2008 with an estimated NAV of $30.71,
for a total return over the relevant time period of -43.36%. The difference
between the actual NAV total return of US12OF of -42.39% and the expected total
return based on the Benchmark Futures Contracts of -43.36% was an error over the
time period of 0.97%, which is to say that US12OF’s actual total return exceeded
the benchmark result by that percentage. Management believes that a portion
of the difference between the actual return and the expected benchmark
return can be attributed to the impact of the interest that US12OF collects on
its cash and cash equivalent holdings. During 2008, US12OF received interest
income of $151,396, which is equivalent to a weighted average interest rate of
1.85% for 2008. In addition, during the year ended December 31, 2008, US12OF
also collected $4,000 from its Authorized Purchasers creating or redeeming
baskets of units. This income also contributed to US12OF’s actual return. During
2008, US12OF incurred total net expenses of $70,046. Income from interest and
Authorized Purchaser collections net of expenses was $85,350, which is
equivalent to a weighted average net interest rate of 7.96% for
2008.





By
comparison, for the period from December 6, 2007, which is the date US12OF’s
units first began trading on the AMEX, to December 31, 2007, the actual total
return of US12OF as measured by changes in its NAV was 8.46%. This is based on
an initial NAV of $50.00 on June 27, 2007 and an ending NAV as of
December 31, 2007 of $54.23. During this time period, US12OF made no
distributions to its unitholders. However, if US12OF’s daily changes in its NAV
had instead exactly tracked the changes in the daily return of the Benchmark
Futures Contracts, US12OF would have ended 2007 with an estimated NAV of $54.14,
for a total return over the relevant time period of 8.28%. The difference
between the actual NAV total return of US12OF of 8.46% and the expected total
return based on the Benchmark Futures Contracts of 8.28% was an error over the
time period of 0.18%, which is to say that US12OF’s actual total return exceeded
the benchmark result by that percentage. Management believes that a portion
of the difference between the actual return and the expected benchmark
return can be attributed to the impact of the interest that US12OF collects on
its cash and cash equivalent holdings. During the period from June 27, 2007 to
December 31, 2007, US12OF received interest income of $49,954, which is
equivalent to a weighted average interest rate of 3.41% for 2007. In addition,
during the period from June 27, 2007 to December 31, 2007, US12OF also collected
$2,000 from its Authorized Purchasers creating or redeeming baskets of units.
This income also contributed to US12OF’s actual return. During the period from
June 27, 2007 to December 31, 2007, US12OF incurred total expenses of
$13,161.  Income from interest and Authorized Purchaser collections
net of expenses was $38,793, which is equivalent to a weighted average net
interest rate of 2.65% for the period from June 27, 2007 to December 31,
2007.

There are
currently three factors that have impacted or are most likely
to impact US12OF’s ability to accurately track its
Benchmark Futures Contracts.





First,
US12OF may buy or sell its holdings in the then current Benchmark Futures
Contracts at a price other than the closing settlement price of that contract on
the day during which US12OF executes the trade. In that case, US12OF may pay a
price that is higher, or lower, than that of the Benchmark Futures
Contracts, which could cause the changes in the daily NAV of US12OF to
either be too high or too low relative to the changes in the Benchmark Futures
Contracts. In 2009, management attempted to minimize the effect of these
transactions by seeking to execute its purchase or sale of the
Benchmark Futures Contracts at, or as close as possible to, the end of the
day settlement price. However, it may not always be possible for US12OF to
obtain the closing settlement price and there is no assurance that failure to
obtain the closing settlement price in the future will not adversely impact
US12OF’s attempt to track the Benchmark Futures Contracts over
time.




Second,
US12OF earns interest on its cash, cash equivalents and Treasury
holdings. US12OF is not required to distribute any portion of its income to its
unitholders and did not make any distributions to unitholders in 2009. Interest
payments, and any other income, were retained within the portfolio and added to
US12OF’s NAV. When this income exceeds the level of US12OF’s expenses for its
management fee, brokerage commissions and other expenses (including ongoing
registration fees, licensing fees and the fees and expenses of the
independent directors of the General Partner), US12OF will realize a net yield
that will tend to cause daily changes in the NAV of US12OF to track slightly
higher than daily changes in the average of the prices of
the Benchmark Futures Contracts. During the year ended December 31,
2009, US12OF earned, on an annualized basis, approximately 0.14% on its cash
holdings. It also incurred cash expenses on an annualized basis of 0.60% for
management fees and approximately 0.03% in brokerage commission costs related to
the purchase and sale of futures contracts, and 0.47% for other expenses. The
foregoing fees and expenses resulted in a net yield on an annualized basis of
approximately 0.96% and affected US12OF’s ability to track its benchmark. If
short-term interest rates rise above the current levels, the level of deviation
created by the yield would decrease. Conversely, if short-term interest rates
were to decline, the amount of error created by the yield would increase. When
short-term yields drop to a level lower than the combined expenses of the
management fee and the brokerage commissions, then the tracking error becomes a
negative number and would tend to cause the daily returns of the NAV to
underperform the daily returns of the Benchmark Futures
Contracts.




Third,
US12OF may hold Other Crude Oil-Related Investments in its portfolio that
may fail to closely track the Benchmark Futures Contracts’ total return
movements. In that case, the error in tracking the Benchmark Futures Contracts
could result in daily changes in the NAV of US12OF that are either too high, or
too low, relative to the daily changes in the Benchmark Futures Contracts.
During 2009, US12OF did not hold any Other Crude Oil-Related Investments.
However, there can be no assurance that in the future US12OF will not make use
of such Other Crude Oil-Related Investments which may have the effect of
increasing transaction related expenses and result in increased tracking
error.




Term Structure of Crude Oil Futures
Prices and the Impact on Total Returns.Several factors determine the
total return from investing in a futures contract position. One factor that
impacts the total return that will result from investing in near month
crude oil futures contracts and “rolling” those contracts forward each month is
the price relationship between the current near month contract and the next
month contracts. For example, if the price of the near month contract is higher
than the next month contract (a situation referred to as “backwardation” in the
futures market), then absent any other change there is a tendency for the price
of a next month contract to rise in value as it becomes the near month contract
and approaches expiration. Conversely, if the price of a near month contract is
lower than the next month contract (a situation referred to as “contango” in the
futures market), then absent any other change there is a tendency for the price
of a next month contract to decline in value as it becomes the near month
contract and approaches expiration.


80




As an
example, assume that the price of crude oil for immediate delivery (the “spot”
price), was $50 per barrel, and the value of a position in the near month
futures contract was also $50. Over time, the price of the barrel of crude oil
will fluctuate based on a number of market factors, including demand for
oil relative to its supply. The value of the near month contract will likewise
fluctuate in reaction to a number of market factors. If investors seek to
maintain their position in a near month contract and not take delivery of the
oil, every month they must sell their current near month contract as it
approaches expiration and invest in the next month contract.





If the
futures market is in backwardation, e.g., when the expected price of crude oil
in the future would be less, the investor would be buying a next month contract
for a lower price than the current near month contract. Hypothetically, and
assuming no other changes to either prevailing crude oil prices or the price
relationship between the spot price, the near month contract and the next month
contract (and ignoring the impact of commission costs and the interest earned on
Treasuries, cash and/or cash equivalents), the value of the next month contract
would rise as it approaches expiration and becomes the new near month contract.
In this example, the value of the $50 investment would tend to rise faster than
the spot price of crude oil, or fall slower. As a result, it would be possible
in this hypothetical example for the spot price of crude oil to have risen to
$60 after some period of time, while the value of the investment in the futures
contract would have risen to $65, assuming backwardation is large enough or
enough time has elapsed. Similarly, the spot price of crude oil could have
fallen to $40 while the value of an investment in the futures contract could
have fallen to only $45. Over time, if backwardation remained constant, the
difference would continue to increase.





If the
futures market is in contango, the investor would be buying a next month
contract for a higher price than the current near month contract.
Hypothetically, and assuming no other changes to either prevailing crude oil
prices or the price relationship between the spot price, the near month contract
and the next month contract (and ignoring the impact of commission costs and the
interest earned on cash), the value of the next month contract would fall as it
approaches expiration and becomes the new near month contract. In this example,
it would mean that the value of the $50 investment would tend to rise slower
than the spot price of crude oil, or fall faster. As a result, it would be
possible in this hypothetical example for the spot price of crude oil to
have risen to $60 after some period of time, while the value of the investment
in the futures contract will have risen to only $55, assuming contango is large
enough or enough time has elapsed. Similarly, the spot price of crude oil could
have fallen to $45 while the value of an investment in the futures contract
could have fallen to $40. Over time, if contango remained constant, the
difference would continue to increase.




The chart
below compares the price of the near month contract to the average price of the
near 12 months over the last 10 years (2000-2009) for light, sweet crude oil.
When the price of the near month contract is higher than the average price of
the near 12 month contracts, the market would be described as being in
backwardation. When the price of the near month contract is lower than the
average price of the near 12 month contracts, the market would be described as
being in contango. Although the prices of the near month contract and the
average price of the near 12 month contracts do tend to move up or down
together, it can be seen that at times the near month prices are clearly higher
than the average price of the near 12 month contracts (backwardation), and other
times they are below the average price of the near 12 month contracts
(contango).


81








*PAST PERFORMANCE IS NOT NECESSARILY
INDICATIVE OF FUTURE RESULTS





An
alternative way to view the same data is to subtract the dollar price of the
average dollar price of the near 12 month contracts for light, sweet crude oil
from the dollar price of the near month contract for light, sweet crude oil. If
the resulting number is a positive number, then the near month price is higher
than the average price of the near 12 months and the market could be described
as being in backwardation. If the resulting number is a negative number, then
the near month price is lower than the average price of the near 12 months and
the market could be described as being in contango. The chart below shows the
results from subtracting the average dollar price of the near 12 month contracts
from the near month price for the 10 year period between 2000 and
2009.


82








*PAST PERFORMANCE
IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS





An
investment in a portfolio that involved owning only the near month contract
would likely produce a different result than an investment in a portfolio that
owned an equal number of each of the near 12 months’ worth of contracts.
Generally speaking, when the crude oil futures market is in backwardation, the
near month only portfolio would tend to have a higher total return than the 12
month portfolio. Conversely, if the crude oil futures market was in contango,
the portfolio containing 12 months’ worth of contracts would tend to outperform
the near month only portfolio. The chart below shows the annual results of
owning a portfolio consisting of the near month contract and a portfolio
containing the near 12 months’ worth of contracts. In addition, the chart shows
the annual change in the spot price of light, sweet crude oil. In this example,
each month, the near month only portfolio would sell the near month contract at
expiration and buy the next month out contract. The portfolio holding an equal
number of the near 12 months’ worth of contracts would sell the near month
contract at expiration and replace it with the contract that becomes the new
twelfth month contract.


83








*PAST PERFORMANCE IS NOT NECESSARILY
INDICATIVE OF FUTURE RESULTS





As seen
in the chart above, there have been periods of both positive and negative annual
total returns for both hypothetical portfolios over the last 10 years. In
addition, there have been periods during which the near month only approach had
higher returns, and periods where the 12 month approach had higher total
returns. The above chart does not represent the performance history of US12OF or
any affiliated funds.





Historically,
the crude oil futures markets have experienced periods of contango and
backwardation, with backwardation being in place more often than contango.
During 2006 and the first half of 2007, these markets experienced contango.
However, starting early in the third quarter of 2007, the crude oil futures
market moved into backwardation. The crude oil markets remained in backwardation
until late in the second quarter of 2008 when they moved into contango. The
crude oil markets remained in contango until late in the third quarter of 2008,
when the markets moved into backwardation. Early in the fourth quarter of 2008,
the crude oil market moved back into contango and remained in contango for the
balance of 2008. Throughout the rest of 2009, the crude oil market remained
in contango.  During parts of January and February 2009, the level of
contango was unusually steep. Crude oil inventories, which reached historic
levels in January and February 2009 and which appear to be the primary cause of
the steep level of contango, began to drop in March 2009 and for the balance of
2009. The crude oil futures market remained in contango through the rest
of 2009.





The
General Partner believes that holding futures contracts whose expiration dates
are spread out over a 12 month period of time will cause the total return of
such a portfolio to vary compared to a portfolio that holds only a single
month’s contract (such as the near month contract).  In particular,
the General Partner believes that the total return of a portfolio holding
contracts with a range of expiration months will be impacted differently by the
price relationship between different contract months of the same commodity
future compared to the total return of a portfolio consisting of the near month
contract. The General Partner believes that based on historical evidence a
portfolio that held futures contracts with a range of expiration dates spread
out over a 12 month period of time would typically be impacted less by the
positive effect of backwardation, and less by the negative effect of contango,
compared to a portfolio that held contracts of a single near month. As a result,
absent the impact of any other factors, a portfolio of 12 different monthly
contracts would tend to have a lower total return than a near month only
portfolio in a backwardation market and a higher total return in a contango
market. However there can be no assurance that such historical
relationships would provide the same or similar results in the
future.


84





Periods
of contango or backwardation do not materially impact US12OF’s investment
objective of having the percentage changes in its per unit NAV track the
percentage changes in the average of the prices of the Benchmark Futures
Contracts since the impact of backwardation and contango tended to equally
impact the percentage changes in price of both US12OF’s units and the
Benchmark Futures Contracts. It is impossible to predict with any degree of
certainty whether backwardation or contango will occur in the future. It is
likely that both conditions will occur during different periods.




Crude Oil Market. During the
year ended December 31, 2009, crude oil prices were impacted by several factors.
On the consumption side, demand remained weak inside and outside the United
States as global economic growth, including emerging economies such as China and
India, remained weak to negative for the first quarter of the year. On the
supply side, efforts to reduce production by OPEC to more closely match global
consumption were only partially successful. This divergence between production
and consumption has led to large build-ups in crude oil inventories and
contributed to weak oil prices.  However, crude oil prices did finish
2009 approximately 52.10% higher than at the beginning of the year, as investors
looked forward to improvements in the global economy. Management believes,
however, that should the global economic situation remain weak, there is a
meaningful possibility that crude oil prices could retreat from their current
levels.





Crude Oil Price Movements in
Comparison to Other Energy Commodities and Investment Categories. The
General Partner believes that investors frequently measure the degree to which
prices or total returns of one investment or asset class move up or down in
value in concert with another investment or asset class. Statistically, such a
measure is usually done by measuring the correlation of the price movements of
the two different investments or asset classes over some period of time. The
correlation is scaled between 1 and -1, where 1 indicates that the two
investment options move up or down in price or value together, known as
“positive correlation,” and -1 indicating that they move in completely opposite
directions, known as “negative correlation.” A correlation of 0 would mean that
the movements of the two are neither positively or negatively correlated, known
as “non-correlation.” That is, the investment options sometimes move up and down
together and other times move in opposite directions.





For the
ten year time period between 2000 and 2009, the chart below compares the monthly
movements of crude oil prices versus the monthly movements of the prices of
several other energy commodities, such as natural gas, heating oil, and unleaded
gasoline, as well as several major non-commodity investment asset classes, such
as large cap U.S. equities, U.S. government bonds and global equities. It can be
seen that over this particular time period, the movement of crude oil on a
monthly basis was not strongly correlated, positively or negatively, with the
movements of large cap U.S. equities, U.S. government bonds or global equities.
However, movements in crude oil had a strong positive correlation to movements
in natural gas and unleaded gasoline. Finally, crude oil had a positive, but
weaker, correlation with heating oil.

PAST PERFORMANCE IS NOT NECESSARILY
INDICATIVE OF FUTURE RESULTS





The chart
below covers a more recent, but much shorter, range of dates than the above
chart. Over the one year period ended December 31, 2009, crude oil continued to
have a strong positive correlation with heating oil and unleaded gasoline.
During this period, it also had aslightly
weakercorrelation
with the movements of natural gas than it had displayed over the ten year period
ended December 31, 2009. Notably, the correlation between crude oil and both
large cap U.S. equities and global equities, which had been essentially
non-correlated over the ten year period ended December 31, 2009, displayed
results that indicated that they had a mildly positive correlation over this
shorter time period, particularly due to the recent downturn in the U.S.
economy. Finally, the results showed that crude oil and U.S. government bonds,
which had essentially been non-correlated for the ten year period ended December
31, 2009, were weakly negatively correlated over this more recent time
period.

PAST PERFORMANCE IS NOT NECESSARILY
INDICATIVE OF FUTURE RESULTS


86





Investors
are cautioned that the historical price relationships between crude oil and
various other energy commodities, as well as other investment asset classes, as
measured by correlation may not be reliable predictors of future price movements
and correlation results. The results pictured above would have been different if
a different range of dates had been selected. The General Partner believes that
crude oil has historically not demonstrated a strong correlation with equities
or bonds over long periods of time. However, the General Partner also believes
that in the future it is possible that crude oil could have long term
correlation results that indicate prices of crude oil more closely track the
movements of equities or bonds. In addition, the General Partner believes that,
when measured over time periods shorter than ten years, there will always be
some periods where the correlation of crude oil to equities and bonds will be
either more strongly positively correlated or more strongly negatively
correlated than the long term historical results suggest.





The
correlations between crude oil, natural gas, heating oil and gasoline are
relevant because the General Partner endeavors to invest US12OF’s assets in
crude oil Futures Contracts and Crude Oil Interests so that daily changes in
US12OF’s NAV correlate as closely as possible with daily changes in the price of
the Benchmark Oil Futures Contracts. If certain other fuel-based commodity
futures contracts do not closely correlate with the crude oil Futures
Contracts then their use could lead to greater tracking error. As noted, the
General Partner also believes that the changes in the price of the Benchmark Oil
Futures Contracts will closely correlate with changes in the spot price of
light, sweet crude oil.





Critical
Accounting Policies





Preparation
of the financial statements and related disclosures in compliance with
accounting principles generally accepted in the United States of America
requires the application of appropriate accounting rules and guidance, as well
as the use of estimates. US12OF’s application of these policies involves
judgments and actual results may differ from the estimates used.




The
General Partner has evaluated the nature and types of estimates that
it makes in preparing US12OF’s financial statements and related
disclosures and has determined that the valuation of its investments which
are not traded on a United States or internationally recognized futures exchange
(such as forward contracts and over-the-counter contracts) involves a critical
accounting policy.  The values which are used by US12OF for its forward
contracts are provided by its commodity broker who uses market prices when
available, while over-the-counter contracts are valued based on the present
value of estimated future cash flows that would be received from or paid to a
third party in settlement of these derivative contracts prior to their delivery
date and valued on a daily basis. In addition, US12OF estimates interest income
on a daily basis using prevailing interest rates earned on its cash and cash
equivalents. These estimates are adjusted to the actual amount received on
a monthly basis and the difference, if any, is not considered
material.




Liquidity
and Capital Resources





US12OF
has not made, and does not anticipate making, use of borrowings or other lines
of credit to meet its obligations. US12OF has met, and it is anticipated that
US12OF will continue to meet, its liquidity needs in the normal course of
business from the proceeds of the sale of its investments or from the
Treasuries, cash and/or cash equivalents that it intends to hold at all times.
US12OF’s liquidity needs include: redeeming units, providing margin deposits for
its existing oil Futures Contracts or the purchase of additional crude oil
Futures Contracts and posting collateral for its over-the-counter contracts and
payment of its expenses, summarized below under “Contractual
Obligations.”





US12OF
currently generates cash primarily from (i) the sale of Creation Baskets and
(ii) interest earned on Treasuries, cash and/or cash equivalents. US12OF has
allocated substantially all of its net assets to trading in Crude Oil Interests.
US12OF invests in Crude Oil Interests to the fullest extent possible without
being leveraged or unable to satisfy its current or potential margin or
collateral obligations with respect to its investments in Futures Contracts and
Other Crude Oil-Related Investments. A significant portion of the NAV is held in
cash and cash equivalents that are used as margin and as collateral for
US12OF’s trading in Crude Oil Interests. The balance of the net assets is held
in US12OF’s account at its custodian bank. Interest earned on US12OF’s
interest-bearing funds is paid to US12OF. In prior periods, the amount of cash
earned by US12OF from the sale of Creation Baskets and from interest has
exceeded the amount of cash required to pay US12OF expenses. However, during the
year ended December 31, 2009, US12OF’s expenses exceeded the interest income
US12OF earned and the cash earned from the sale of Creation Baskets. During the
year ended December 31, 2009, US12OF was forced to use other assets to pay cash
expenses, which could cause a drop in US12OF’s NAV over time.


87





US12OF’s
investment in Crude Oil Interests may be subject to periods of illiquidity
because of market conditions, regulatory considerations and other reasons. For
example, most commodity exchanges limit the fluctuations in Futures
Contracts prices during a single day by regulations referred to as “daily
limits.” During a single day, no trades may be executed at prices beyond the
daily limit. Once the price of an Futures Contract has increased or
decreased by an amount equal to the daily limit, positions in the contracts can
neither be taken nor liquidated unless the traders are willing to effect trades
at or within the specified daily limit. Such market conditions could prevent
US12OF from promptly liquidating its positions in Futures Contracts. During
the year ended December 31, 2009, US12OF was not forced to purchase or
liquidate any of its positions while daily limits were in effect; however,
US12OF cannot predict whether such an event may occur in the
future.




Prior to
the initial offering of US12OF, all payments with respect to US12OF’s expenses
were paid by the General Partner.  US12OF does not have an obligation
or intention to refund such payments by the General Partner.  The
General Partner is under no obligation to pay US12OF’s current or future
expenses.  Since the initial offering of units, US12OF has been
responsible for expenses relating to (i) management fees, (ii) brokerage
fees and commissions, (iii) licensing fees for the use of intellectual
property, (iv) ongoing registration expenses in connection with offers and
sales of its units subsequent to the initial offering, (v) other expenses,
including certain tax reporting costs, (vi) fees and expenses of the independent
directors of the General Partner and (vii) other extraordinary expenses not in
the ordinary course of business, while the General Partner has been responsible
for expenses relating to the fees of the Marketing Agent, the Administrator and
the Custodian. If the General Partner and US12OF are unsuccessful in
raising sufficient funds to cover these respective expenses or in locating any
other source of funding, US12OF will terminate and investors may lose all or
part of their investment.





Market
Risk





Trading
in Futures Contracts and Other Crude Oil-Related Investments, such as
forwards, involves US12OF entering into contractual commitments to purchase
or sell oil at a specified date in the future. The aggregate market value of
the contracts will significantly exceed US12OF’s future cash requirements
since US12OF intends to close out its open positions prior to settlement. As a
result, US12OF is generally only subject to the risk of loss arising
from the change in value of the contracts. US12OF considers the “fair value” of
its derivative instruments to be the unrealized gain or loss on the contracts.
The market risk associated with US12OF’s commitments to purchase oil is limited
to the aggregate market value of the contracts held. However, should US12OF
enter into a contractual commitment to sell oil, it would be required to make
delivery of the oil at the contract price, repurchase the contract at prevailing
prices or settle in cash. Since there are no limits on the future price of oil,
the market risk to US12OF could be unlimited.




US12OF’s
exposure to market risk depends on a number of factors, including the
markets for oil, the volatility of interest rates and foreign exchange rates,
the liquidity of the Futures Contracts and Other Crude Oil-Related
Investments markets and the relationships among the contracts held by US12OF.
Drastic market occurrences could ultimately lead to the loss of all or
substantially all of an investor’s capital.




Credit
Risk





When
US12OF enters into Futures Contracts and Other Crude Oil-Related
Investments, it is exposed to the credit risk that the counterparty will not be
able to meet its obligations. The counterparty for the Futures Contracts
traded on the NYMEX and on most other foreign futures exchanges is the
clearinghouse associated with the particular exchange. In general,
clearinghouses are backed by their members who may be required to share in the
financial burden resulting from the nonperformance of one of their members and,
therefore, this additional member support should significantly reduce credit
risk. Some foreign exchanges are not backed by their clearinghouse members but
may be backed by a consortium of banks or other financial institutions. There
can be no assurance that any counterparty, clearinghouse, or their members or
their financial backers will satisfy their obligations to US12OF in such
circumstances.


88




The
General Partner attempts to manage the credit risk of US12OF by following
various trading limitations and policies. In particular, US12OF generally posts
margin and/or holds liquid assets that are approximately equal to the market
value of its obligations to counterparties under the Futures Contracts and Other
Oil-Related Investments it holds. The General Partner has implemented procedures
that include, but are not limited to, executing and clearing trades only with
creditworthy parties and/or requiring the posting of collateral or margin by
such parties for the benefit of US12OF to limit its credit
exposure.





UBS
Securities, US12OF’s commodity broker, or any other broker that may be retained
by US12OF in the future, when acting as US12OF’s futures commission merchant in
accepting orders to purchase or sell Futures Contracts on United States
exchanges, is required by CFTC regulations to separately account for and
segregate as belonging to US12OF, all assets of US12OF relating to domestic
Futures Contracts trading. These futures commission merchants are not allowed to
commingle US12OF’s assets with its other assets. In addition, the CFTC requires
commodity brokers to hold in a secure account US12OF’s assets related to foreign
Futures Contracts trading.





If, in
the future, US12OF purchases over-the-counter contracts, see “Item 7A.
Quantitative and Qualitative Disclosures About Market Risk” for a discussion of
over-the-counter contracts.





As of December 31, 2009, US12OF had
deposits in domestic and foreign financial institutions, including cash
investments in money market funds, in the amount of $145,075,490. This amount is
subject to loss should these institutions cease operations.





Off
Balance Sheet Financing





As of
December 31, 2009, US12OF has no loan guarantee, credit support or other
off-balance sheet arrangements of any kind other than agreements entered into in
the normal course of business, which may include indemnification provisions
relating to certain risks that service providers undertake in performing
services which are in the best interests of US12OF. While US12OF’s exposure
under these indemnification provisions cannot be estimated, they are not
expected to have a material impact on US12OF’s financial position.





Redemption
Basket Obligation





In order
to meet its investment objective and pay its contractual obligations described
below, US12OF requires liquidity to redeem units, which redemptions must be
in blocks of 100,000 units called Redemption Baskets. US12OF has to
date satisfied this obligation by paying from the cash or cash equivalents
it holds or through the sale of its Treasuries in an amount proportionate
to the number of units being redeemed.




Contractual
Obligations





US12OF’s
primary contractual obligations are with the General Partner. In return for its
services, the General Partner is entitled to a management fee calculated monthly
as a fixed percentage of US12OF’s NAV, currently 0.60% of NAV on its average
daily net assets.




The
General Partner agreed to pay the start-up costs associated with the
formation of US12OF, primarily its legal, accounting and other costs in
connection with the General Partner’s registration with the CFTC as a
CPO  and the registration and listing of US12OF and its units with
the SEC, FINRA and the AMEX, respectively. However, since US12OF’s initial
offering of units, offering costs incurred in connection with registering and
listing additional units of US12OF are directly borne on an ongoing basis by
US12OF, and not by the General Partner.





The
General Partner pays the fees of the Marketing Agent and the fees of the
Custodian and transfer agent, BBH&Co., as well as BBH&Co.’s fees for
performing administrative services, including in connection with the preparation
of US12OF’s financial statements and its SEC and CFTC reports. The General
Partner and US12OF have also entered into a licensing agreement with
the NYMEX pursuant to which US12OF and the affiliated funds managed by the
General Partner pay a licensing fee to the NYMEX. US12OF also pays the fees and
expenses associated with its tax accounting and reporting
requirements.


89





In addition to the General Partner’s
management fee, US12OF pays its brokerage fees (including fees to a futures
commission merchant), over-the-counter dealer spreads, any licensing fees
for the use of intellectual property, and, subsequent to the initial offering,
registration and other fees paid to the SEC, FINRA, or other regulatory agencies
in connection with the offer and sale of units, as well as legal, printing,
accounting and other expenses associated therewith, and extraordinary expenses.
The latter are expenses not incurred in the ordinary course of US12OF’s
business, including expenses relating to the indemnification of any person
against liabilities and obligations to the extent permitted by law and under the
LP Agreement, the bringing or defending of actions in law or in equity or
otherwise conducting litigation and incurring legal expenses and the settlement
of claims and litigation. Commission payments to a futures commission
merchant are on a contract-by-contract, or round turn, basis. US12OF also pays a
portion of the fees and expenses of the independent directors of the General
Partner. See Note 3 to the Notes to Financial Statements.





The
parties cannot anticipate the amount of payments that will be required under
these arrangements for future periods, as US12OF’s NAVs and trading levels to
meet its investment objectives will not be known until a future date. These
agreements are effective for a specific term agreed upon by the parties with an
option to renew, or, in some cases, are in effect for the duration of US12OF’s
existence. Either party may terminate these agreements earlier for certain
reasons described in the agreements.





Item
7A.     Quantitative and Qualitative Disclosures About
Market Risk.





Over-the-Counter Derivatives




In the
future, US12OF may purchase over-the-counter contracts. Unlike most of the
exchange-traded oil Futures Contracts or exchange-traded options on such
futures, each party to an over-the-counter contract bears the credit risk that
the other party may not be able to perform its obligations under its
contract.




Some
crude oil-based derivatives transactions contain fairly generic terms and
conditions and are available from a wide range of participants. Other crude
oil-based derivatives have highly customized terms and conditions and are not as
widely available. Many of these over-the-counter contracts are cash-settled
forwards for the future delivery of crude oil- or petroleum-based fuels that
have terms similar to the Futures Contracts. Others take the form of “swaps” in
which the two parties exchange cash flows based on pre-determined formulas tied
to the spot price of crude oil, forward crude oil prices or crude oil
futures prices. For example, US12OF may enter into over-the-counter derivative
contracts whose value will be tied to changes in the difference between
the spot price of light, sweet crude oil, the price of Futures
Contracts traded on the NYMEX and the prices of other Futures Contracts in
which US12OF may invest.




To
protect itself from the credit risk that arises in connection with such
contracts, US12OF may enter into agreements with each counterparty that provide
for the netting of its overall exposure to such counterparty, such as the
agreements published by the International Swaps and Derivatives Association,
Inc. US12OF also may require that the counterparty be highly rated and/or
provide collateral or other credit support to address US12OF’s exposure to the
counterparty. In addition, it is also possible for US12OF and its counterparty
to agree to clear their agreement through an established futures clearinghouse
such as those connected to the NYMEX or the ICE Futures. In that event, US12OF
would no longer have credit risk of its original counterparty, as the
clearinghouse would now be US12OF’s counterparty. US12OF would still retain any
price risk associated with its transaction.





The
creditworthiness of each potential counterparty is assessed by the General
Partner. The General Partner assesses or reviews, as appropriate, the
creditworthiness of each potential or existing counterparty to an
over-the-counter contract pursuant to guidelines approved by the Board.
Furthermore, the General Partner on behalf of US12OF only enters into
over-the-counter contracts with counterparties who are, or are affiliates of,
(a) banks regulated by a United States federal bank regulator, (b)
broker-dealers regulated by the SEC, (c) insurance companies domiciled in the
United States, or (d) producers, users or traders of energy, whether or not
regulated by the CFTC. Any entity acting as a counterparty shall be regulated in
either the United States or the United Kingdom unless otherwise approved by the
Board after consultation with its legal counsel. Existing counterparties are
also reviewed periodically by the General Partner.


90





US12OF
anticipates that the use of Other Crude Oil-Related Investments together with
its investments in Futures Contracts will produce price and total return results
that closely track the investment goals of US12OF. However, there can be no
assurance of this. Over-the-counter contracts may result in higher
transaction-related expenses than the brokerage commissions paid in connection
with the purchase of Futures Contracts, which may impact US12OF’s ability to
successfully track the Benchmark Futures Contract.




US12OF
may employ spreads or straddles in its trading to mitigate the differences in
its investment portfolio and its goal of tracking the average of the prices of
the Benchmark Futures Contract. US12OF would use a spread when it chooses to
take simultaneous long and short positions in futures written on the same
underlying asset, but with different delivery months. The effect of holding such
combined positions is to adjust the sensitivity of US12OF to changes in the
price relationship between futures contracts which will expire sooner and those
that will expire later. US12OF would use such a spread if the General Partner
felt that taking such long and short positions, when combined with the rest of
its holdings, would more closely track the investment goals of US12OF, or if the
General Partner felt it would lead to an overall lower cost of trading to
achieve a given level of economic exposure to movements in oil prices. US12OF
would enter into a straddle when it chooses to take an option position
consisting of a long (or short) position in both a call option and put option.
The economic effect of holding certain combinations of put options and call
options can be very similar to that of owning the underlying futures contracts.
US12OF would make use of such a straddle approach if, in the opinion of the
General Partner, the resulting combination would more closely track the
investment goals of US12OF or if it would lead to an overall lower cost of
trading to achieve a given level of economic exposure to movements in oil
prices.




During
the year ended December 31, 2009, US12OF did not employ any hedging methods such
as those described above since all of its investments were made over an
exchange. Therefore, during the year ended December 31, 2009, US12OF was not
exposed to counterparty risk.

Auditors’
Report on Internal Control over Financial Reporting




To the
Partners of


United
States 12 Month Oil Fund, LP




We have
audited the internal control over financial reporting of United States 12 Month
Oil Fund, LP (the “Fund”) as of December 31, 2009, based on criteria established
in Internal Control — Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission. The Fund’s management is
responsible for maintaining effective internal control over financial reporting
and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Management’s Annual Report on Internal
Control Over Financial Reporting. Our responsibility is to express an opinion on
the Fund’s internal control over financial reporting based on our
audit.





We
conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, testing
and evaluating the design and operating effectiveness of internal control based
on the assessed risk, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable
basis for our opinion.




A
company’s internal control over financial reporting is a process designed by, or
under the supervision of, the company’s principal executive and principal
financial officers, or persons performing similar functions, and effected by the
company’s board of directors, management, and other personnel to provide
reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A company’s internal control over
financial reporting includes those policies and procedures that (1) pertain
to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company;
(2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and expenditures of
the company are being made only in accordance with authorizations of management
and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the
financial statements.





Because
of the inherent limitations of internal control over financial reporting,
including the possibility of collusion or improper management override of
controls, material misstatements due to error or fraud may not be prevented or
detected on a timely basis. Also, projections of any evaluation of the
effectiveness of the internal control over financial reporting to future periods
are subject to the risk that the controls may become inadequate because of
changes in conditions, or that the degree of compliance with the policies or
procedures may deteriorate.





In our
opinion, the Fund maintained, in all material respects, effective internal
control over financial reporting as of December 31, 2009, based on the criteria
established in Internal Control — Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission.




We have
also audited, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), the financial statements as of and for the year
ended December 31, 2009, of the Fund and our report dated March 16, 2010
expressed an unqualified opinion on those financial statements.

Report
of Independent Registered Public Accounting Firm





To the
Partners of


United
States 12 Month Oil Fund, LP

States 12 Month Oil Fund, LP (the “Fund”) as of December 31, 2009 and
2008, including the schedule of investments as of December 31, 2009 and

are the responsibility of the Fund’s management. Our responsibility is to
express an opinion on these financial statements based on our
audits.





We
conducted our audits in accordance with standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

opinion, the financial statements referred to above present fairly, in all
material respects, the financial position of United States 12 Month Oil
Fund, LP as of December 31, 2009 and 2008, and the results of its
operations and its cash flows for the years ended December 31, 2009 and 2008 and

conformity with accounting principles generally accepted in the United States of
America.





We also
have audited, in accordance with standards of the Public Company Accounting

Notes
to Financial Statements


For
the years ended December 31, 2009 and 2008 and the period ended December 31,
2007




NOTE
1 - ORGANIZATION AND BUSINESS





The
United States 12 Month Oil Fund, LP (“US12OF”) was organized as a limited
partnership under the laws of the state of Delaware on June 27,
2007.  US12OF is a commodity pool that issues limited partnership
units (“units”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE
Arca”). Prior to November 25, 2008, US12OF’s units traded on the American Stock
Exchange (the “AMEX”). US12OF will continue in perpetuity, unless terminated
sooner upon the occurrence of one or more events as described in
its Amended and Restated Agreement of Limited Partnership dated as of
December 4, 2007 (the “LP Agreement”). The investment objective of US12OF is for
the changes in percentage terms of its units’ net asset value to reflect the
changes in percentage terms of the spot price of light, sweet crude
oil delivered to Cushing, Oklahoma, as measured by the changes in the average of
the prices of the 12 futures contracts on light, sweet crude oil as
traded on the New York Mercantile Exchange (the “NYMEX”), consisting
of the near month contract to expire and the contracts for the following 11
months for a total of 12 consecutive months’ contracts, except when the near
month contract is within two weeks of expiration, in which case it will be
measured by the futures contracts that are the next month contract to expire and
the contracts for the following 11 consecutive months, less US12OF’s
expenses. US12OF accomplishes its objective through investments in futures
contracts for light, sweet crude oil, and other types of crude oil, heating oil,
gasoline, natural gas and other petroleum-based fuels that are traded on the
NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Futures
Contracts”) and other oil-related investments such as cash-settled options on
oil Futures Contracts, forward contracts for oil and over-the-counter
transactions that are based on the price of crude oil, heating oil, gasoline,
natural gas and other petroleum-based fuels, oil Futures Contracts and indices
based on the foregoing (collectively, “Other Crude Oil-Related
Investments”). As of December 31, 2009, US12OF held 2,016 Futures Contracts
traded on the NYMEX.




US12OF
commenced investment operations on December 6, 2007 and has a fiscal year ending
on December 31. United States Commodity Funds LLC (formerly known as Victoria
Bay Asset Management, LLC) (the “General Partner”) is responsible for the
management of US12OF. The General Partner is a member of the National
Futures Association (the “NFA”) and became a commodity pool operator
registered with the Commodity Futures Trading Commission effective December 1,
2005. The General Partner is also the general partner of the United States Oil
Fund, LP (“USOF”), the United States Natural Gas Fund, LP (“USNG”), the
United States Gasoline Fund, LP (“UGA”) and the United States Heating Oil Fund,
LP (“USHO”), which listed their limited partnership units on the AMEX under the
ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 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 USOF’s, USNG’s, UGA’s and
USHO’s units commenced trading on the NYSE Arca on November 25,
2008.  The General Partner is also the general partner of the United
States Short Oil Fund, LP (“USSO”) and the United States 12 Month Natural Gas
Fund, LP, which listed their limited partnership units on the NYSE Arca on
September 24, 2009 and November 18, 2009, respectively. The General Partner has
also filed registration statements to register units of the United States Brent
Oil Fund, LP (“USBO”) and the United States Commodity Index Funds Trust
(“USCI”).





US12OF
issues units to certain authorized purchasers (“Authorized Purchasers”) by
offering baskets consisting of 100,000 units (“Creation Baskets”) through
ALPS Distributors, Inc. (the “Marketing Agent”). The purchase price for a
Creation Basket is based upon the net asset value of a unit 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.





In
addition, Authorized Purchasers pay US12OF a $1,000 fee for each order placed
to create one or more Creation Baskets or redeem one or more baskets
consisting of 100,000 units (“Redemption Baskets”). Units may be purchased
or sold on a nationally recognized securities exchange in smaller increments
than a Creation Basket or Redemption Basket. Units purchased or sold on a
nationally recognized securities exchange are not purchased or sold at the net
asset value of US12OF but rather at market prices quoted on such
exchange.





In
December 2007, US12OF initially registered 11,000,000 units on Form S-1 with the
SEC. On December 6, 2007, US12OF listed its units on the AMEX under the ticker
symbol “USL”. On that day, US12OF established its initial net asset value by
setting the price at $50.00 per unit and issued 300,000 units in exchange for
$15,000,000. US12OF also commenced investment operations on December 6, 2007 by
purchasing Futures Contracts traded on the NYMEX based on light,
sweet crude oil. As of December 31, 2008, US12OF had registered a total of
111,000,000 units.

NOTE
2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES





Revenue
Recognition





Commodity
futures contracts, forward contracts, physical commodities, and related options
are recorded on the trade date. All such transactions are recorded on the
identified cost basis and marked to market daily. Unrealized gains or losses on
open contracts are reflected in the statement of financial condition and in the
difference between the original contract amount and the market value (as
determined by exchange settlement prices for futures contracts and related
options and cash dealer prices at a predetermined time for forward contracts,
physical commodities, and their related options) as of the last business day of
the year or as of the last date of the financial statements. Changes in the
unrealized gains or losses between periods are reflected in the statement of
operations. US12OF earns interest on its assets denominated in U.S. dollars on
deposit with the futures commission merchant at the 90-day Treasury bill
rate. In addition, US12OF earns interest on funds held at the custodian at
prevailing market rates earned on such investments.





Brokerage
Commissions





Brokerage
commissions on all open commodity futures contracts are accrued on a full-turn
basis.




Income
Taxes





US12OF is
not subject to federal income taxes; each partner reports his/her allocable
share of income, gain, loss deductions or credits on his/her own income tax
return.




Additions
and Redemptions





Authorized
Purchasers may purchase Creation Baskets or redeem Redemption Baskets only in
blocks of 100,000 units equal to the net asset value of the units calculated
shortly after the close of the core trading session on the NYSE Arca on the day
the order is placed.





US12OF
receives or pays the proceeds from units sold or redeemed within three business
days after the trade date of the purchase or redemption. The amounts due from
Authorized Purchasers are reflected in US12OF’s statement of financial condition
as receivable for units sold, and amounts payable to Authorized Purchasers upon
redemption are reflected as payable for units redeemed.





Partnership
Capital and Allocation of Partnership Income and Losses





Profit or
loss shall be allocated among the partners of US12OF in proportion to the number
of units each partner holds as of the close of each month. The General Partner
may revise, alter or otherwise modify this method of allocation as described in
the LP Agreement.





Calculation
of Net Asset Value





US12OF’s
net asset value is calculated on each NYSE Arca trading day by taking the
current market value of its total assets, subtracting any liabilities and
dividing the amount by the total number of units issued and outstanding. US12OF
uses the closing price for the contracts on the relevant exchange on that day to
determine the value of contracts held on such exchange.





Net
Income (Loss) per Unit





Net
income (loss) per unit is the difference between the net asset value per
unit at the beginning of each period and at the end of each period. The
weighted average number of units outstanding was computed for purposes of
disclosing net income (loss) per weighted average unit. The weighted average
units are equal to the number of units outstanding at the end of the period,
adjusted proportionately for units redeemed based on the amount of time the
units were outstanding during such period. There were no units held by the
General Partner at December 31, 2009.


103




Offering
Costs





Offering
costs incurred in connection with the registration of additional units after the
initial registration of units are borne by US12OF. These costs include
registration fees paid to regulatory agencies and all legal, accounting,
printing and other expenses associated with such offerings. These costs will be
accounted for as a deferred charge and thereafter amortized to expense over
twelve months on a straight line basis or a shorter period if
warranted.





Cash
Equivalents





Cash
equivalents include money market funds and overnight deposits or time deposits
with original maturity dates of three months or less.





Use
of Estimates





The
preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires US12OF’s
management to make estimates and assumptions that affect the reported amount of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of the revenue
and expenses during the reporting period. Actual results could differ from those
estimates and assumptions.




NOTE 3
- FEES PAID BY THE FUND AND RELATED PARTY TRANSACTIONS





General
Partner Management Fee





Under the
LP Agreement, the General Partner is responsible for investing the assets of
US12OF in accordance with the objectives and policies of US12OF. In addition,
the General Partner has arranged for one or more third parties to provide
administrative, custody, accounting, transfer agency and other necessary
services to US12OF. For these services, US12OF is contractually obligated to pay
the General Partner a fee, which is paid monthly, that is equal to 0.60% per
annum of average daily net assets.




Ongoing
Registration Fees and Other Offering Expenses





US12OF
pays all costs and expenses associated with the
ongoing registration of its units subsequent to the initial offering.
These costs include registration or other fees paid to regulatory agencies in
connection with the offer and sale of units, and all legal, accounting, printing
and other expenses associated with such offer and sale. For the years ended
December 31, 2009 and 2008 and the period ended December 31, 2007, US12OF
incurred $107,883, $0 and $0, respectively, in registration fees and other
offering expenses.





Directors’
Fees and Expenses




US12OF is
responsible for paying its portion of the directors’ and officers’ liability
insurance of the General Partner and the fees and expenses of the independent
directors of the General Partner who are also the General Partner’s audit
committee members. US12OF shares these fees and expenses with USOF, USNG,
UGA, USHO, USSO and US12NG based on the relative assets of each fund, computed
on a daily basis. These fees and expenses for the calendar year 2009 amounted to
a total of $433,046 for all funds and US12OF’s portion of such fees and expenses
was $12,326.  For the calendar years 2008 and 2007, these fees and
expenses were $282,000 and $286,000, respectively, and US12OF’s portion of such
fees and expenses was $1,762 and $350, respectively.


104


Licensing
Fees





As
discussed in Note 4, US12OF entered into a licensing agreement with the
NYMEX on January 16, 2008. Pursuant to the agreement, US12OF and the affiliated
funds managed by the General Partner pay a licensing fee that is equal to 0.04%
for the first $1,000,000,000 of combined assets of the funds and 0.02% for
combined assets above $1,000,000,000. During the years ended December 31,
2009 and 2008 and the period ended December 31, 2007, USO12F incurred $33,993,
$2,854 and $540, respectively, under this arrangement.





Investor
Tax Reporting Cost





The fees
and expenses associated with US12OF’s audit expenses and tax accounting and
reporting requirements are paid by US12OF. These costs are approximately
$315,000 for the year ended December 31, 2009.




Other
Expenses and Fees and Expense Waivers




In
addition to the fees described above, US12OF pays all brokerage fees and
other expenses in connection with the operation of US12OF, excluding costs and
expenses paid by the General Partner as outlined in Note 4. The General
Partner, though under no obligation to do so, agreed to pay certain expenses, to
the extent that such expenses exceed 0.15% (15 basis points) of US12OF’s NAV, on
an annualized basis, through March 31, 2009 after which date such payments were
no longer necessary.  The General Partner has no obligation to make
such payment into subsequent periods.





NOTE
4 - CONTRACTS AND AGREEMENTS





US12OF is
party to a marketing agent agreement, dated as of November 13, 2007,
with the Marketing Agent and the General Partner, whereby the Marketing
Agent provides certain marketing services for US12OF as outlined in the
agreement. The fee of the Marketing Agent, which is borne by the General
Partner, is equal to 0.06% on US12OF’s assets up to $3 billion; and 0.04% on
US12OF’s assets in excess of $3 billion.





The above

the custodian, which are determined by the parties from time to time. In
addition, US12OF is party to an administrative agency agreement, dated October
5, 2007, with the General Partner and BBH&Co., whereby BBH&Co. acts as

Currently,
the General Partner pays BBH&Co. for its services, in the foregoing
capacities, a minimum amount of $75,000 annually for its custody, fund
accounting and fund administration services rendered to US12OF and each of the
affiliated funds managed by the General Partner, as well as a $20,000 annual fee
for its transfer agency services. In addition, the General Partner pays
BBH&Co. an asset-based charge of (a) 0.06% for the first $500 million of
US12OF’s, USOF’s, USNG’s, UGA’s, USHO’s, USSO’s and US12NG’s combined net
assets, (b) 0.0465% for US12OF’s, USOF’s, USNG’s, UGA’s, USHO’s, USSO’s and
US12NG’s combined net assets greater than $500 million but less than $1 billion,
and (c) 0.035% once US12OF’s, USOF’s, USNG’s, UGA’s, USHO’s, USSO’s and US12NG’s
combined net assets exceed $1 billion. The annual minimum amount will not apply
if the asset-based charge for all accounts in the aggregate exceeds $75,000. The
General Partner also pays transaction fees ranging from $7.00 to $15.00 per
transaction.





US12OF
has entered into a brokerage agreement with UBS Securities LLC (“UBS
Securities”). The agreement requires UBS Securities to provide services to
US12OF in connection with the purchase and sale of Futures Contracts and Other
Crude Oil-Related Investments that may be purchased and sold by or through UBS
Securities for US12OF’s account. The agreement provides that UBS Securities
charge US12OF commissions of approximately $7 per round-turn trade, plus
applicable exchange and NFA fees for Futures Contracts and options on Futures
Contracts.


105





On
January 16, 2008, US12OF and the NYMEX entered into a licensing agreement
whereby US12OF was granted a non-exclusive license to use certain of the NYMEX’s
settlement prices and service marks. The agreement has an effective date of
December 4, 2007 with respect to US12OF. Under the licensing
agreement, US12OF and the affiliated funds managed by the General Partner pay
the NYMEX an asset-based fee for the license, the terms of which are described
in Note 3.





US12OF
expressly disclaims any association with the NYMEX or endorsement of US12OF by
the NYMEX and acknowledges that “NYMEX” and “New York Mercantile Exchange” are
registered trademarks of the NYMEX.





NOTE
5 - FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND
CONTINGENCIES





US12OF engages
in the trading of futures contracts and options on futures contracts
(collectively, “derivatives”). US12OF is exposed to both market risk, which is
the risk arising from changes in the market value of the contracts, and credit
risk, which is the risk of failure by another party to perform according to the
terms of a contract.





US12OF
may enter into futures contracts and options on futures contracts to gain
exposure to changes in the value of an underlying commodity. A futures contract
obligates the seller to deliver (and the purchaser to accept) the future
delivery of a specified quantity and type of a commodity at a specified time and
place. Some futures contracts may call for physical delivery of the asset, while
others are settled in cash. The contractual obligations of a buyer or seller may
generally be satisfied by taking or making physical delivery of the underlying
commodity or by making an offsetting sale or purchase of an identical futures
contract on the same or linked exchange before the designated date of
delivery.





The
purchase and sale of futures contracts and options on futures contracts require
margin deposits with a futures commission merchant. Additional deposits may be
necessary for any loss on contract value. The Commodity Exchange Act requires a
futures commission merchant to segregate all customer transactions and assets
from the futures commission merchant’s proprietary activities.





Futures
contracts involve, to varying degrees, elements of market risk (specifically
commodity price risk) and exposure to loss in excess of the amount of variation
margin. The face or contract amounts reflect the extent of the total exposure
US12OF has in the particular classes of instruments. Additional risks associated
with the use of futures contracts are an imperfect correlation between movements
in the price of the futures contracts and the market value of the underlying
securities and the possibility of an illiquid market for a futures
contract.





All of
the futures contracts currently traded by US12OF are exchange-traded. The risks
associated with exchange-traded contracts are generally perceived to be less
than those associated with over-the-counter transactions since, in
over-the-counter transactions, US12OF must rely solely on the credit of its
respective individual counterparties. However, in the future, if US12OF
were to enter into non-exchange traded contracts, it would be subject to the
credit risk associated with counterparty non-performance. The credit risk from
counterparty non-performance associated with such instruments is the net
unrealized gain, if any. US12OF also has credit risk since the sole counterparty
to all domestic and foreign futures contracts is the clearinghouse for the
exchange on which the relevant contracts are traded. In addition, US12OF bears
the risk of financial failure by the clearing broker.





US12OF’s
cash and other property, such as U.S. Treasuries, deposited with a futures
commission merchant are considered commingled with all other customer funds
subject to the futures commission merchant’s segregation requirements. In the
event of a futures commission merchant’s insolvency, recovery may be limited to
a pro rata share of segregated funds available. It is possible that the
recovered amount could be less than the total of cash and other property
deposited. The insolvency of a futures commission merchant could result in the
complete loss of US12OF’s assets posted with that futures commission merchant;
however, the vast majority of US12OF’s assets are held in Treasuries, cash
and/or cash equivalents with US12OF’s custodian and would not be impacted by the
insolvency of a futures commission merchant. Also, the failure or insolvency of
US12OF’s custodian could result in a substantial loss of US12OF’s
assets.





US12OF
invests a portion of its cash in money market funds that seek to maintain a
stable net asset value. US12OF is exposed to any risk of loss associated with an
investment in these money market funds. As of December 31, 2009 and 2008, US12OF
had deposits in domestic and foreign financial institutions, including cash
investments in money market funds, in the amounts of $145,075,490 and
$9,005,535, respectively. This amount is subject to loss should these
institutions cease operations.


106





For
derivatives, risks arise from changes in the market value of the contracts.
Theoretically, US12OF is exposed to a market risk equal to the value
of futures contracts purchased and unlimited liability on such contracts sold
short. As both a buyer and a seller of options, US12OF pays or receives a
premium at the outset and then bears the risk of unfavorable changes in the
price of the contract underlying the option.





US12OF’s
policy is to continuously monitor its exposure to market and counterparty risk
through the use of a variety of financial, position and credit exposure
reporting controls and procedures. In addition, US12OF has a policy of
requiring review of the credit standing of each broker or counterparty with
which it conducts business.





The
financial instruments held by US12OF are reported in its statement of
financial condition at market or fair value, or at carrying amounts that
approximate fair value, because of their highly liquid nature and short-term
maturity.

NOTE
8 - FAIR VALUE OF FINANCIAL INSTRUMENTS





Effective
January 1, 2008, US12OF adopted Accounting Standards Codification 820 – Fair
Value Measurements and Disclosures (“ASC 820”).  ASC 820 defines fair
value, establishes a framework for measuring fair value in generally accepted
accounting principles, and expands disclosures about fair value
measurement.  The changes to past practice resulting from the
application of ASC 820 relate to the definition of fair value, the methods used
to measure fair value, and the expanded disclosures about fair value
measurement. ASC 820 establishes a fair value hierarchy that distinguishes
between (1) market participant assumptions developed based on market data
obtained from sources independent of US12OF (observable inputs) and (2) US12OF’s
own assumptions about market participant assumptions developed based on the best
information available under the circumstances (unobservable
inputs).  The three levels defined by the ASC 820 hierarchy are as
follows:




Level I –
Quoted prices (unadjusted) in active markets for identical assets or
liabilities that the reporting entity has the ability to access at the
measurement date.





Level II
– Inputs other than quoted prices included within Level I that are observable
for the asset or liability, either directly or indirectly. Level II assets
include the following: quoted prices for similar assets or liabilities in active
markets, quoted prices for identical or similar assets or liabilities in markets
that are not active, inputs other than quoted prices that are observable for the
asset or liability, and inputs that are derived principally from or corroborated
by observable market data by correlation or other means (market-corroborated
inputs).





Level III
– Unobservable pricing input at the measurement date for the asset or liability.
Unobservable inputs shall be used to measure fair value to the extent that
observable inputs are not available.





In some
instances, the inputs used to measure fair value might fall in different levels
of the fair value hierarchy. The level in the fair value hierarchy within which
the fair value measurement in its entirety falls shall be determined based on
the lowest input level that is significant to the fair value measurement in its
entirety.

following tables summarize the valuation of US12OF’s securities at December 31,
2009 and 2008 using the fair value hierarchy:

NOTE
9 – RECENT ACCOUNTING PRONOUNCEMENTS




In March
2008, the Financial Accounting Standards Board released Accounting Standards
Codification 815 – Derivatives and Hedging (“ASC 815”). ASC 815 requires
qualitative disclosures about objectives and strategies for using derivatives,
quantitative disclosures about fair value amounts of, and gains and losses on,
derivative instruments, and disclosures about credit-risk-related contingent
features in derivative agreements. US12OF adopted ASC 815 on January 1,
2009.




In
January 2010, the Financial Accounting Standards Board issued Accounting
Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about Fair Value
Measurements.” ASU No. 2010-06 clarifies existing disclosure and requires
additional disclosures regarding fair value measurements. Effective for interim
and annual reporting periods beginning after December 15, 2009, entities will be
required to disclose significant transfers into and out of Level 1 and 2
measurements in the fair value hierarchy and the reasons for those transfers.
Effective for fiscal years beginning after December 15, 2010, and for interim
periods within those fiscal years, entities will need to disclose information
about purchases, sales, issuances and settlements of Level 3 securities on a
gross basis, rather than as a net number as currently required. The General
Partner is currently evaluating the impact ASU No. 2010-06 will have on the
financial statement disclosures.


109




NOTE
10 – SUBSEQUENT EVENTS





US12OF
has performed an evaluation of subsequent events through March 16, 2010, which
is the date the financial statements were available to be issued. This
evaluation did not result in any subsequent events that necessitated disclosures
and/or adjustments.

Financial Disclosure.

Item
9A.  Controls and Procedures.





Disclosure
Controls and Procedures




US12OF
maintains disclosure controls and procedures that are designed to ensure that
material information required to be disclosed in US12OF’s periodic reports
filed or submitted under the Exchange Act is recorded, processed, summarized and
reported within the time period specified in the SEC’s rules and
forms.




The duly
appointed officers of the General Partner, including its chief executive
officer and chief financial officer, who perform functions equivalent
to those of a principal executive officer and principal financial officer of
US12OF if US12OF had any officers, have evaluated the effectiveness of US12OF’s
disclosure controls and procedures and have concluded that the disclosure
controls and procedures of US12OF have been effective as of the end of the
period covered by this annual report on Form 10-K.





Management’s
Annual Report on Internal Control Over Financial Reporting




US12OF is
responsible for establishing and maintaining adequate internal control over
financial reporting. US12OF’s internal control system is designed to provide
reasonable assurance to its management and the board of directors of the General
Partner regarding the preparation and fair presentation of published financial
statements. All internal control systems, no matter how well designed, have
inherent limitations. Therefore, even those systems determined to be effective
can provide only reasonable assurance with respect to financial statement
preparation and presentation. Management’s report on internal control over
financial reporting is set forth above under the heading, “Management’s Annual
Report on Internal Control Over Financial Reporting” in Item 8 of this annual
report on Form 10-K.





Change
in Internal Control Over Financial Reporting




There
were no changes in US12OF’s internal control over financial reporting during
US12OF’s last fiscal quarter that have materially affected, or are reasonably
likely to materially affect, US12OF’s internal control over financial
reporting.




Item
9B.  Other Information.




Monthly
Account Statements




Pursuant
to the requirement under Rule 4.22 under the CEA, each month US12OF publishes an
account statement for its unitholders, which includes a Statement of Income
(Loss) and a Statement of Changes in NAV. The account statement is furnished to
the SEC on a current report on Form 8-K pursuant to Section 13 or 15(d) of the
Exchange Act and posted each month on US12OF’s website at
www.unitedstates12monthoilfund.com.

Audit
Committee





The Board
of the General Partner has an audit committee which is made up of the three
independent directors (Peter M. Robinson, Gordon L. Ellis, and Malcolm R. Fobes
III). The audit committee is governed by an audit committee charter that is
posted on US12OF’s website at www.unitedstates12monthoilfund.com. Any unitholder
of US12OF may also obtain a printed copy of the audit committee charter, free of
charge, by calling 1-800-920-0259. The Board has determined that each member of
the audit committee meets the financial literacy requirements of the NYSE Arca
and the audit committee charter. The Board has further determined that each of
Messrs. Ellis and Fobes have accounting or related financial management
expertise, as required by the NYSE Arca, such that each of them is considered an
“Audit Committee Financial Expert” as such term is defined in Item 407(d)(5) of
Regulation S-K.




Other
Committees





Since the
individuals who perform work on behalf of US12OF are not compensated by US12OF,
but instead by the General Partner, US12OF does not have a compensation
committee. Similarly, since the Directors noted above serve on the board of
directors of the General Partner, there is no nominating committee of the board
of directors that acts on behalf of US12OF. The General Partner believes that it
is necessary for each member of the Board of Directors to possess many qualities
and skills. The General Partner further believes that all directors should
possess a considerable amount of business management and educational
experience.  There have not been any vacancies on the General
Partner’s Board of Directors since the commencement of operations of USOF in
April 2006; however, if such a vacancy were to occur, the members of the Board
of Directors would consider a candidate’s management experience as well as
his/her background, stature, conflicts of interest, integrity and
ethics.  In connection with this, the Board of Directors would also
consider issues of diversity, such as diversity of gender, race and national
origin, education, professional experience and differences in viewpoints and
skills. The Board of Directors does not have a formal policy with respect to
diversity; however, the Board of Directors believes that it is essential that
the Board members represent diverse viewpoints.





Corporate
Governance Policy





The Board
of the General Partner has adopted a Corporate Governance Policy that applies to
US12OF, USOF, USNG, UGA, USHO, USSO, US12NG, USBO, and USCI. US12OF has posted
the text of the Corporate Governance Policy on its website at
www.unitedstates12monthoilfund.com. Any unitholder of US12OF may also
obtain a printed copy of the Corporate Governance Policy, free of charge, by
calling 1-800-920-0259.





Code
of Ethics





The
General Partner of US12OF has adopted a Code of Business Conduct and Ethics (the
“Code of Ethics”) that applies to its principal executive officer, principal
financial officer, principal accounting officer or controller, or persons
performing similar functions, and also to US12OF. US12OF has posted the text of
the Code of Ethics on its website at
www.unitedstates12monthoilfund.com. Any unitholder of US12OF may also
obtain a printed copy of the Code of Ethics, free of charge, by calling
1-800-920-0259. US12OF intends to disclose any amendments or waivers to the Code
of Ethics applicable to the General Partner’s principal executive officer,
principal financial officer, principal accounting officer or controller, or
persons performing similar functions, on its website.





Executive
Sessions of the Non-Management Directors





In
accordance with the Corporate Governance Policy of the General Partner, the
non-management directors of the Board (who are the same as the independent
directors of the Board) meet separately from the other directors in regularly
scheduled executive sessions, without the presence of Management Directors or
executive officers of the General Partner. The non-management directors have
designated Malcolm R. Fobes III to preside over each such executive session.
Interested parties who wish to make their concerns known to the non-management
directors may communicate directly with Mr. Fobes by writing to 475 Milan Drive,
No. 103, San Jose, CA  95134-2453 or by e-mail at
uscf.director@gmail.com.

Board
Leadership Structure and Role in Risk Oversight





The Board
of the General Partner is led by a Chairman, Nicholas Gerber, who is also the
President and CEO of the General Partner.  The Board’s
responsibilities include (i) the selection, evaluation, retention and succession
of the Chief Executive Officer and the oversight of the selection and
performance of other executive officers, (ii) understanding, reviewing and
monitoring the implementation of strategic plans, annual operating plans and
budgets, (iii) the selection and oversight of US12OF’s independent auditors and
the oversight of US12OF’s financial statements, (iv) advising management on
significant issues, (v) the review and approval of significant company actions
and certain other matters, (vi) nominating directors and committee members and
overseeing effective corporate governance and (vii) the consideration of other
constituencies, such as the General Partner’s and US12OF’s customers, employees,
suppliers and the communities impacted by US12OF. The non-management directors
have designated Malcolm R. Fobes III as the presiding independent
director.  Mr. Fobes’s role as the presiding independent director
includes presiding over each executive session of the non-management directors,
facilitating communications by shareholders and employees with the
non-management directors and may also include representing the non-management
directors with respect to certain matters as to which the views of the
non-management directors are sought pursuant to US12OF’s Corporate Governance
Policy.





The Board
believes that Mr. Gerber is best situated to serve as Chairman of the General
Partner because he is the director most familiar with the business of the
General Partner, including investing in the futures contracts and other
commodity interests in order to track the benchmark futures contracts of US12OF
and the Related Public Funds.  Because of his background, he is most
capable of effectively leading the discussion and execution of new strategic
objectives.  The independent directors of the General Partner are
actively involved in the oversight of the General Partner and, because of their
varied backgrounds, provide different perspectives in connection with the
oversight of the General Partner, US12OF and the Related Public Funds. The
General Partner’s independent directors bring expertise from outside the General
Partner and the commodities industry, while Mr. Gerber brings company-specific
and industry-specific experience and expertise. The Board of Directors believes
that the combined role of Chairman and Chief Executive Officer facilitates
information flow between management and the Board of Directors, including the
independent directors, which is essential to effective governance.





Risk
Management





The full
Board of Directors is actively involved in overseeing the management and
operation of the General Partner, including oversight of the risks that face
US12OF and the Related Public Funds.  For example, the Board of
Directors has adopted an Investment Policy and a Policy for Use of
Derivatives.  The policies are intended to ensure that the General
Partner take prudent and careful action while entering into and managing
investments taken by US12OF including Futures Contracts or Other
Gasoline-Related Investments such as over-the-counter swap
contracts.  Additionally, the policies are intended to provide
assurance that there is sufficient flexibility in controlling risks and returns
associated with the use of investments by US12OF.  The policies, among
other things, limit US12OF’s ability to have too high of a concentration of its
assets in non-exchange traded futures contracts or cleared swap contracts or
concentrating its investments in too few counterparties, absent prior approval
from the Board of Directors.  Existing counterparties are reviewed
periodically by the Board of Directors to ensure that they continue to meet the
criteria outlined in the policies.  The Board of Directors tasks
management with assessing risks, including market risk, credit risk, liquidity
risk, cash flow risk, basis risk, legal and tax risk, settlement risk, and
operational risk.





The Board
of Directors also determines compensation payable to employees of the General
Partner, including the portfolio managers of each of US12OF and the Related
Public Funds.  The compensation of certain employees of the General
Partner is, in part, based on the amount of assets under management by US12OF
and the Related Public Funds.  The Board of Directors feels that
compensating certain employees, in part, based on the amount of assets under
management is appropriate since having more assets in a fund generally reflects
that investors perceive the fund’s investment objective is being
met.  There are certain risks that may arise as a result of a growth
in assets under management.  For example, if position limits are
imposed on US12OF and the assets under management continue to increase, then
US12OF may not be able to invest solely in the Benchmark Futures Contract and
may have to invest in over-the-counter swap contracts or Other Gasoline-Related
Investments as it seeks to track its benchmark.  Other Futures
Contracts in which US12OF may invest may not track changes in the price of the
Benchmark Futures Contract.  Other Gasoline-Related Investments,
including over-the-counter swap contracts, may also expose US12OF to increased
counterparty credit risk and may be less liquid and more difficult to value than
Futures Contracts.  US12OF and the Related Public Funds ameliorate the
potential credit, liquidity and valuation risks by fully collateralizing any
over-the-counter swap contracts or other investments.  The Board of
Directors, in making compensation decisions, considers whether a compensation
arrangement would expose US12OF or the Related Public Funds to additional risks
and whether the risks posed by such arrangement are consistent with the best
interests of US12OF’s investors.

Other
Information





In
addition to the certifications of the Chief Executive Officer and Chief
Financial Officer of the General Partner filed or furnished with this annual
report on Form 10-K regarding the quality of US12OF’s public disclosure, US12OF
will submit, within 30 days after filing this annual report on Form 10-K, to the
NYSE Arca a certification of the Chief Executive Officer of the General Partner
certifying that he is not aware of any violation by US12OF of NYSE Arca
corporate governance listing standards.





Section 16(a)
Beneficial Ownership Reporting Compliance




Section 16(a)
of the Exchange Act requires directors and executive officers of the General
Partner and persons who are beneficial owners of at least 10% of US12OF’s units
to file with the SEC an Initial Statement of Beneficial Ownership of Securities
on Form 3 within 10 calendar days of first becoming a director, executive
officer or beneficial owner of at least 10% of US12OF’s units and a Statement of
Changes of Beneficial Ownership of Securities on Form 4 within 2 business days
of a subsequent acquisition or disposition of units of US12OF.  To
US12OF’s knowledge, based upon a review of copies of reports furnished to US12OF
with respect to the fiscal year ended December 31, 2009 and upon the written
representations of the directors and executive officers of the General Partner,
all of such persons have filed all required reports. However, Mr. John Hyland
did not timely file an Initial Statement of Beneficial Ownership of Securities
on Form 3 upon becoming an executive officer of the General Partner in
compliance with the applicable reporting deadline. Mr. Hyland has since
filed an Initial Statement of Beneficial Ownership of Securities on Form
3.  As of the date of this annual report on Form 10-K, Mr. Hyland does
not own any units of US12OF.





Item
11.    Executive Compensation.

US12OF
does not directly compensate any of the executive officers noted above. The

Partner an annualized fee of 0.60% of NAV on all of its average daily net

(1)
            Mr.
      Fobes serves as chairman of the audit committee of the General Partner and
      receives additional compensation in recognition of the additional
      responsibilities he has undertaken in this
role.





Item
12.    Security Ownership of Certain Beneficial Owners and
Management and Related Stockholder Matters.





None of
the directors or executive officers of the General Partner, nor the employees of
US12OF own any units of U12OF. In addition, US12OF is not aware of any 5%
holder of its units.





Item
13.    Certain Relationships and Related Transactions, and
Director Independence.




Certain
Relationships and Related Transactions




US12OF
has and will continue to have certain relationships with the General Partner and
its affiliates. However, there have been no direct financial transactions
between US12OF and the directors or officers of the General Partner that have
not been disclosed herein. See “Item 11. Executive Compensation” and “Item
12. Security Ownership of Certain Beneficial Owners and Management and Related
Stockholder Matters.” Any transaction with a related person that must be
disclosed in accordance with SEC Regulation S-K item 404(a), including financial
transactions by US12OF with directors or executive officers of the General
Partner or holders of beneficial interests in the General Partner or US12OF of
more than 5%, will be subject to the provisions regarding “Resolutions of
Conflicts of Interest; Standard of Care” as set forth in Section 7.7 of the LP
Agreement and will be reviewed and approved by the audit committee of the Board
of the General Partner.





Director
Independence





In
February 2010, the Board undertook a review of the independence of the directors
of the General Partner and considered whether any director has a material
relationship or other arrangement with the General Partner, US12OF or the
Related Public Funds that could compromise his ability to exercise independent
judgment in carrying out his responsibilities. As a result of this review, the
Board determined that each of Messrs. Fobes, Ellis and Robinson is an
“independent director,” as defined under the rules of NYSE Arca.





Item
14.    Principal Accountant Fees and Services.

Tax fees
consist of fees paid to Spicer Jeffries LLP for professional services rendered
in connection with tax compliance and partnership income tax return
filings.




The audit
committee has established policies and procedures which are intended to control
the services provided by US12OF’s independent auditors and to monitor their
continuing independence.  Under these policies and procedures, no
audit or permitted non-audit services (including fees and terms thereof), except
for the de minimis
exceptions for non-audit services described in Section 10A(i)(1)(B) of the
Exchange Act, may be undertaken by US12OF’s independent auditors unless the
engagement is specifically pre-approved by the audit committee.  The
audit committee may form and delegate authority to subcommittees consisting of
one or more members when appropriate, including the authority to grant
pre-approvals of audit and permitted non-audit services, provided that decisions
of such subcommittee to grant pre-approvals must be presented to the full audit
committee at its next scheduled meeting.
