in the oil rim participating area of 50.68% as of February 28, 1989. Subsequent decreases
in BP Alaskas participation in oil rim ownership do not affect calculation of Royalty
Production from the 1989 Working Interests and have not decreased the Trusts Royalty
Interest.(b)

increases in BP Alaskas gas cap ownership do not affect calculation of Royalty Production
from the 1989 Working Interests and have not increased the Trusts Royalty Interest. 14

##### Table of Contents




    
    Royalty Production from the Prudhoe Bay field is projected to decline and will
eventually cease.
  
    
    Construction of a proposed gas pipeline from the North Slope of Alaska could accelerate
the decline in Royalty Production from the Prudhoe Bay field.
       23




---



##### Table of Contents




    
    Royalty Production from the Prudhoe Bay field may be adversely affected by the recent
changes to the Alaska Production Tax Statutes.
  
    
    Royalty payments by BP Alaska to the Trust are unpredictable, because they depend on
Cushing, Oklahoma WTI spot prices, which have been volatile in recent years, and on the
volume of production from the 1989 Working Interests, which may vary from quarter to
quarter in the future.
 http://tonto.eia.doe.gov/dnav/pet/hist/rwtcM.htm
   
    
    Prudhoe Bay field oil production could be shut in partially or entirely from time to
time as a result of damage to or failures of field pipelines or equipment.
  24




---



##### Table of Contents




    
    Oil production from the Prudhoe Bay Unit could be interrupted by damage to the
Trans-Alaska Pipeline System from natural causes, accidents, deliberate attacks or
declining oil flows.
  
    
    Production from the 1989 Working Interests may be interrupted or discontinued by BP
Alaska.
  
    
    There are potential conflicts of interest between BP Alaska and the Trust that could
affect the royalties paid to Unit holders.

BP Prudhoe Bay Royalty Trust
 
 Notes to Financial Statements
(Prepared on a modified basis of cash receipts and disbursements)
December 31, 2009
 (1)
    
    Formation of the Trust and OrganizationBP Prudhoe Bay Royalty Trust (the Trust), a grantor trust, was created as a Delaware statutory
trust pursuant to a Trust Agreement dated February 28, 1989 among the Standard Oil Company
(Standard Oil), BP Exploration (Alaska) Inc. (BP Alaska), The Bank of New York Mellon (the
Trustee) and BNY Mellon Trust of Delaware (successor to The Bank of New York (Delaware)), as
co-trustee. Standard Oil and BP Alaska are indirect wholly owned subsidiaries of BP p.l.c.
(BP).On February 28, 1989, Standard Oil conveyed an overriding royalty interest (the Royalty
Interest) to the Trust. The Trust was formed for the sole purpose of owning and administering
the Royalty Interest. The Royalty Interest represents the right to receive, effective February
28, 1989, a per barrel royalty (the Per Barrel Royalty) of 16.4246% on the lesser of (a) the
first 90,000 barrels of the average actual daily net production of oil and condensate per
quarter or (b) the average actual daily net production of oil and condensate per quarter from BP
Alaskas working interest as of February 28, 1989 in the Prudhoe Bay field, located on the North
Slope of Alaska. Trust Unit holders will remain subject at all times to the risk that production
will be interrupted or discontinued. BP has guaranteed the performance of BP Alaska of its
payment obligations with respect to the Royalty Interest.Effective January 1, 2000, BP Alaska and all other Prudhoe Bay working interest owners
cross-assigned interests in the Prudhoe Bay field pursuant to the Prudhoe Bay Unit Alignment
Agreement. BP Alaska retained all rights, obligations, and liabilities associated with the
Trust.The trustees of the Trust are The Bank of New York Mellon, a New York banking corporation, and
BNY Mellon Trust of Delaware, a Delaware banking corporation. BNY Mellon Trust of Delaware
serves as co-trustee in order to satisfy certain requirements of the Delaware Statutory Trust
Act. The Bank of New York Mellon alone is able to exercise the rights and powers granted to the
Trustee in the Trust Agreement.The Per Barrel Royalty in effect for any day is equal to the price of West Texas Intermediate
crude oil (the WTI Price) for that day less scheduled Chargeable Costs (adjusted for
inflation) and Production Taxes (based on statutory rates then in existence).The Trust is passive, with the Trustee having only such powers as are necessary for the
collection and distribution of revenues, the payment of Trust liabilities, and the protection of
the Royalty Interest. The Trustee, subject to certain conditions, is obligated to establish cash
reserves and borrow funds to pay liabilities of the Trust when they become due. The Trustee may
sell Trust properties only (a) as authorized by a vote of the Trust unit holders, (b) when
necessary to provide for the payment of specific liabilities of the Trust then due (subject to
certain conditions) or (c) upon termination of the Trust. Each Trust Unit issued and outstanding
represents an equal undivided share of beneficial interest in the Trust. Royalty payments are
received by the Trust and distributed to Trust Unit holders, net of Trust expenses, in the month
succeeding the end of each calendar quarter. The Trust will terminate upon the first to occur of
the following events:
 a.
    
    On or prior to December 31, 2010: upon a vote of Trust unit holders of not less than
70% of the outstanding Trust units.

 Notes to Financial Statements
(Prepared on a modified basis of cash receipts and disbursements)
December 31, 2009
 b.
    
    After December 31, 2010: (i) upon a vote of Trust unit holders of not less than 60% of
the outstanding Trust units, or (ii) at such time the net revenues from the Royalty
Interest for two
successive years commencing after 2010 are less than $1,000,000 per year (unless the net
revenues during such period are materially and adversely affected by certain events).
 In order to ensure the Trust has the ability to pay future expenses, the Trust established a
cash reserve account which the Trustee believes is sufficient to pay approximately one years
current and expected liabilities and expenses of the Trust.
 (2)
    
    Basis of AccountingThe financial statements of the Trust are prepared on a modified cash basis and reflect the
Trusts assets, liabilities, corpus, earnings, and distributions, as follows:
 a.
    
    Revenues are recorded when received (generally within 15 days of the end of the
preceding quarter) and distributions to Trust unit holders are recorded when paid.b.
    
    Trust expenses (which include accounting, engineering, legal, and other professional
fees, trustees fees, and out-of-pocket expenses) are recorded on an accrual basis.c.
    
    Cash reserves may be established by the Trustee for certain contingencies that would
not be recorded under generally accepted accounting principles.d.
    
    Amortization of the Royalty Interest is calculated based on the units of production
method. Such amortization is charged directly to the Trust corpus, and does not affect cash
earnings. The daily rate for amortization per net equivalent barrel of oil for the years
ended December 31, 2009, 2008 and 2007 was $0.38, $0.38 and $0.38, respectively. The Trust
evaluates impairment of the Royalty Interest by comparing the undiscounted cash flows
expected to be realized from the Royalty Interest to the carrying value, pursuant to the
Financial Accounting Standards Board Accounting Standards Codification (FASB ASC) 360,
Property, Plant, and Equipment. If the expected future undiscounted cash flows are less
than the carrying value, the Trust recognizes an impairment loss for the difference between
the carrying value and the estimated fair value of the Royalty Interest.
 While these statements differ from financial statements prepared in accordance with accounting
principles generally accepted in the United States of America, the modified cash basis of
reporting revenues and distributions is considered to be the most meaningful because quarterly
distributions to the Trust unit holders are based on net cash receipts. The accompanying
modified cash basis financial statements contain all adjustments necessary to present fairly the
assets, liabilities and corpus of the Trust as of December 31, 2009 and 2008, and the modified
cash earning and distributions and changes in Trust corpus for the years ended December 31,
2009, 2008 and 2007. The adjustments are of a normal recurring nature and are, in the opinion of
the Trustee, necessary to fairly present the results of operations.As of December 31, 2009 and 2008, cash equivalents which represent the cash reserve consist of
U.S. treasury bills with an initial term of less than three months.

 Estimates and assumptions are required to be made regarding assets, liabilities and changes in
Trust corpus resulting from operations when financial statements are prepared. Changes in the
economic environment, financial markets and any other parameters used in determining these
estimates could cause actual results to differ, and the difference could be material.

    Income TaxesThe Trust files its federal tax return as a grantor trust subject to the provisions of subpart E
of Part I of Subchapter J of the Internal Revenue Code of 1986, as amended, rather than as an
association taxable as a corporation. The Trust unit holders are treated as the owners of Trust
income and corpus, and the entire taxable income of the Trust will be reported by the Trust unit
holders on their respective tax returns.If the Trust were determined to be an association taxable as a corporation, it would be treated
as an entity taxable as a corporation on the taxable income from the Royalty Interest, the Trust
unit holders would be treated as shareholders, and distributions to Trust unit holders would not
be deductible in computing the Trusts tax liability as an association.
 (5)
    
    Alaska Oil and Gas Production TaxThe Alaska oil and gas production tax statutes were amended by a bill (the 2006 Amendments)
which became effective in August 2006. The 2006 Amendments replaced an oil production tax levied
at the flat rate of 15% of the gross value at the point of production (the wellhead or field
value) of taxable oil produced from a producers leases or properties in the State of Alaska.
Under the 2006 Amendments, producers were taxed on the production tax value of taxable oil
(gross value at the point of production for the calendar year less the producers direct costs
of exploring for, developing, or producing oil or gas deposits located within the producers
leases or properties in Alaska for the year) at a rate equal to the sum of 22.5% plus a
progressivity rate determined by the average monthly production tax value of the oil produced.
The progressivity rate imposed by the 2006 Amendments was equal to 0.25% times the amount by
which the simple average for each calendar month of the daily production tax values per barrel
of the oil produced during the month exceeded $40 per barrel.In December 2007, a bill (popularly titled Alaskas Fair and Equitable Share or ACES) took
effect which further amended the Alaska oil and gas production tax statutes in certain respects.

December 31, 2009
 ACES changed the basic tax rate from 22.5% to 25% and increased the progressivity rate. If the
producers average monthly production tax value per barrel is greater than $30 but not more than
$92.50, the progressivity tax rate is 0.4% times the amount by which the average monthly
production tax value exceeds $30 per barrel. If the producers average monthly production tax
value per barrel is greater than $92.50, the progressivity tax rate is the sum of 25% and the
product of 0.1% multiplied by the difference between the average monthly production tax value
per barrel and $92.50, except that the sum may not exceed 50%.The Trustee and BP Alaska entered into a letter agreement in October 2006 and an amendment
thereto in January 2008 (the Letter Agreement) to resolve issues associated with the 2006
Amendments and ACES. The Letter Agreement modified the calculation of Production Taxes
in the daily Per Barrel Royalty calculation effective as of August 20, 2006, in the case of the
2006 Amendments, and effective December 20, 2007, in the case of ACES. It also provides
that the retroactivity provisions of the respective tax bills are not applicable to the Per
Barrel Royalty calculation for periods prior to the effective dates of the 2006 Amendments and
ACES.
 (6)
    
    Legal ExpensesThe Trust incurred legal and other expenses as a result of litigation and other issues arising
out of the August 2006 shutdown of the Prudhoe Bay field. Legal fees and expenses contributed
materially to the Trust administrative expenses during 2007, 2008 and 2009.
 (7)
    
    Settlement PaymentIn 2009, the Trust entered into a settlement agreement with BP Alaska to resolve certain issues
related to the temporary shutdown of the Prudhoe Bay field following oil spills on March 2, 2006
and August 6, 2006 and to compromise any claims that the Trust and past, present, and future
holders of Trust units may have relating to conduct by BP Alaska that may have resulted in a
reduction of the royalty payments received by the Trust in 2006, 2007 and 2008. Under the
settlement agreement, BP Alaska paid $29,469,081 into an interest-bearing escrow account, to be
released by the escrow agent and paid to the Trust upon final approval by the Delaware Chancery
Court of the settlement agreement, and the dismissal of certain litigation brought in the United
States District Court for the Southern District of New York against BP Alaska and other parties
having become final.The settlement amount and accrued interest, totaling $29,474,410, was released from escrow and
paid to the Trust on December 24, 2009. See Note 9 below.
 (8)
    
    Royalty Revenue Adjustments
 Certain of the royalty payments received by the Trust in 2009, 2008 and 2007 were adjusted by BP
Alaska to compensate for underpayments or overpayments of the royalties due with respect to the
quarters ended prior to the dates of such payments. Average net production of crude oil and
condensate from the proved reserves allocated to the Trust was less than 90,000 barrels per day
during certain quarters. Royalty payments by BP Alaska with respect to those quarters were based
on estimates by BP Alaska of production levels because actual data was not available by the
dates on which payments were required to be made to the Trust. Subsequent recalculation by BP
Alaska of royalty payments due based on actual production data resulted in the payment
adjustments shown in the table below (in thousands):

BP Prudhoe Bay Royalty Trust
Notes to Financial Statements
(Prepared on a modified basis of cash receipts and disbursements)
December 31, 2009
 (11)
    
    Supplemental Reserve Information and Standardized Measure of Discounted Future Net Cash Flow
Relating to Proved Reserves (Unaudited)
 Pursuant to Statement of FASB ASC 932, Extractive Activities  Oil and Gas, the Trust is
required to include in its financial statements supplementary information regarding estimates of
quantities of proved reserves attributable to the Trust and future net cash flows. The following
information in this note with respect to the year ended December 31, 2009 reflects the adoption
of Securities Exchange Act Release No. 59192, Modernization of Oil and Gas Reportingwhich
became effective for financial statements for fiscal years ending on or after December 31, 2009.
The Trust has not restated reserve information with respect to the years ended December 31, 2007
and 2008 to reflect changes in the methodology for determining proved reserves prescribed by
Release No. 59192.Estimates of proved reserves are inherently imprecise and subjective and are revised over time
as additional data becomes available. Such revisions may often be substantial. Information
regarding estimates of proved reserves attributable to the combined interests of BP Alaska and
the Trust were based on reserve estimates prepared by BP Alaska. BP Alaskas reserve estimates
are believed to be reasonable and consistent with presently known physical data concerning the
size and character of the Field.There is no precise method of allocating estimates of physical quantities of reserve volumes
between BP Alaska and the Trust, since the Royalty Interest is not a working interest and the
Trust does not own and is not entitled to receive any specific volume of reserves from the
Prudhoe Bay field. Reserve volumes attributable to the Trust were estimated by allocating to the
Trust its share of estimated future production from the field, based on the 12-month average WTI
Price for 2009 ($61.18 per barrel), and on the WTI Price on December 31, 2008 ($44.60 per
barrel) and December 31, 2007 ($96.01 per barrel). Because the reserve volumes attributable to
the Trust are estimated using an allocation of reserve volumes based on the estimated future
production and on the current WTI Price, a change in the timing of estimated production or a
change in the WTI price will result in a change in the Trusts estimated reserve volumes.
Therefore, the estimated reserve volumes attributable to the Trust will vary if different
production estimates and prices are used.In addition to production estimates and prices, reserve volumes attributable to the Trust are
affected by the amount of Chargeable Costs that will be deducted in determining the Per Barrel
Royalty. Net proved reserves of oil and condensate attributable to the Trust as of December 31,
2009, 2008 and 2007, based on BP Alaskas latest reserve estimate at such time and the 12-month
average WTI price for 2009 and WTI Prices on December 31, 2008 and 2007, were estimated to be
68, 55 and 98 million barrels, respectively (of which 57, 46 and 87 million barrels,
respectively, are proved developed reserves). Under the provisions of FASB ASC 932, no
consideration can be given to reserves not considered proved at the present time.The standardized measure of discounted future net cash flow relating to proved reserves
disclosure required by FASB ASC 932 assigns monetary amounts to proved reserves based on current
prices. This discounted future net cash flow should not be construed as the current market value
of the Royalty Interest. A market valuation determination would include, among other things,
anticipated price changes and the value of additional reserves not considered proved at the present time or
reserves that may be produced after the currently anticipated end of field life. At December 31,
2009, 2008 and 2007, the standardized measure of discounted future net cash flow relating to
proved reserves attributable to the Trust (estimated in accordance with the provisions of FASB
ASC 932),
