INTRODUCTION

BP Prudhoe Bay Royalty Trust (the Trust) was created as a Delaware business trust by the BP Prudhoe Bay Royalty Trust Agreement
dated February 28, 1989 (the Trust Agreement) among The Standard Oil Company (Standard Oil), BP Exploration (Alaska) Inc. (BP Alaska), The Bank of New York Mellon (formerly named The Bank of New York), as
trustee, and F. James Hutchinson, co-trustee (BNY Mellon Trust of Delaware, formerly named The Bank of New York (Delaware), successor co-trustee). BP Alaska and Standard
Oil are wholly owned subsidiaries of BP p.l.c. (BP).

Effective as of December 15, 2010, The Bank of New York Mellon
(BNYM) resigned as trustee under the Trust Agreement and BP Alaska appointed The Bank of New York Mellon Trust Company, N.A. (the Trust Company) to succeed BNYM as trustee. The Trust Company accepted its appointment and

THE TRUST

Trust Property

The property of the Trust
consists of an overriding royalty interest (the Royalty Interest) and cash and cash equivalents held by the Trustee from time to time. The Royalty Interest entitles the Trust to a royalty on 16.4246% of the lesser of (i) the first
90,000 barrels1 of the average actual daily net production of crude oil and condensate per quarter from the working interest of BP Alaska as of February 28, 1989 in the Prudhoe Bay oil field
located on the North Slope in Alaska or (ii) the average actual daily net production of crude oil and condensate per quarter from that working interest. The Prudhoe Bay field is one of four contiguous North Slope oil fields that are operated by
BP Alaska and are known collectively as the Prudhoe Bay Unit. The Royalty Interest was conveyed to the Trust by an Overriding Royalty Conveyance dated February 27, 1989 from BP Alaska to Standard Oil and a Trust Conveyance
dated February 28, 1989 from Standard Oil to the Trust. Copies of the Overriding Royalty Conveyance and the Trust Conveyance are filed with the SEC as exhibits to this report. The Overriding Royalty Conveyance and the Trust Conveyance are
referred to collectively in this report as the Conveyance.

The Royalty Interest is a
non-operational interest in minerals. The Trust does not have the right to take oil and gas in kind, nor does it have any right to take over operations or to share in any operating decision with respect to BP
Alaskas working interest in the Prudhoe Bay field. BP Alaska is not obligated to continue to operate any well or maintain or attempt to maintain in force any portion of its working interest when, in its reasonable and prudent business
judgment, the well or interest ceases to produce or is not capable of producing oil or gas in paying quantities.

Employees

The Trust has no employees. All administrative functions of the Trust are performed by the Trustee.

Duties and Powers of the Trustee

The duties of the Trustee are specified in the Trust Agreement and the laws of the State of Delaware. BNY Mellon Trust of Delaware has been
appointed co-trustee in order to satisfy the Delaware Statutory Trust Acts requirement that the Trust have at least one trustee resident in, or which has its principal place of business in, Delaware.
However, The Bank of New York Mellon Trust Company, N.A. alone is able to exercise the rights and powers granted to the Trustee in the Trust Agreement. A copy of the Trust Agreement is filed with the SEC as an exhibit to this report.

The basic function of the Trustee is to collect income from the Royalty Interest, to pay all expenses, charges and obligations of the Trust
from the Trusts income and assets, and to pay available cash to Unit holders. Because of the passive nature of the Trusts assets and the restrictions on the power of the Trustee to incur obligations, the only liabilities that the Trust
normally incurs in the conduct of its operations are the Trustees fees and routine administrative expenses, including accounting, legal and other professional fees.

The Trust Agreement grants the Trustee only the rights and powers necessary to achieve the purposes of the Trust. The Trust Agreement
prohibits the Trust from engaging in any business or commercial activity or, with certain exceptions, any investment activity and from using any assets of the Trust to acquire any oil and gas lease, royalty or other mineral interest.

The Trustee is entitled to be indemnified out of the assets of the Trust for any liability or loss incurred by it in the performance of its
duties unless the loss results from its negligence, bad faith or fraud or from expenses incurred in carrying out its duties that exceed the compensation and reimbursement to which it is entitled under the Trust Agreement.

Sales of Royalty Interest; Borrowings and Reserves

With certain exceptions, the Trustee may sell all or part of the Royalty Interest or an interest therein only if authorized to do so by vote of
the holders of 60% of the Units outstanding. However, if the sale is made in order to pay specific liabilities of the Trust then due and involves a part, but not all or substantially all, of the Trust properties, the sale only needs to be approved
by the vote of holders of a majority of the Units. Any sale of Trust properties must be for cash unless otherwise authorized by the Unit holders. The Trustee is obligated to distribute the available net proceeds of any such sale to the Unit holders
after establishing reserves for liabilities of the Trust.

The Trustee has the power to borrow on behalf of the Trust or to sell Trust
assets to pay liabilities of the Trust and to establish a reserve for the payment of liabilities without the consent of the Unit holders under the following circumstances:

The Trustee may borrow from a lender not affiliated with the Trustee if cash on hand is not sufficient to pay current
liabilities and the Trustee has determined that it is not practical to pay such liabilities out of funds anticipated to be available in subsequent quarters and that, without such borrowing, the Trust property is subject to the risk of loss or
diminution in value. To secure payment of its borrowings on behalf of the Trust, the Trustee is authorized to encumber the Trusts assets and to carve out and convey production payments. The borrowing must be on terms which (in the opinion of
an investment banking firm or commercial banking firm selected by the Trustee) are commercially reasonable when compared to other available alternatives. No distributions to Unit holders may be made until the borrowings by the Trust have been repaid
in full.

##### Table of Contents

If the Trustee is unable to borrow to pay Trust liabilities, the Trustee may sell
Trust assets if it determines that the failure to pay the liabilities at a later date will be contrary to the best interest of the Unit holders and that it is not practicable to submit the sale to a vote of the Unit holders. The sale must be made
for cash at a price which (in the opinion of an investment banking firm or commercial banking firm selected by the Trustee) is at least equal to the fair market value of the interest sold and is made on commercially reasonable terms when compared to
other available alternatives.

The Trustee has the right to establish a cash reserve for the payment of material
liabilities of the Trust which may become due if it determines that it is not practical to pay such liabilities out of funds anticipated to be available in subsequent quarters and that, in the absence of a reserve, the Trust property is subject to
the risk of loss or diminution in value or the Trustee is subject to the risk of personal liability for such liabilities.

In order for
the Trustee to borrow, sell assets to pay Trust liabilities or establish a reserve for Trust liabilities, the Trustee must receive an unqualified written legal opinion that the contemplated action will not adversely affect the classification of the
Trust as a grantor trust for federal income tax purposes or cause the income from the Trust to be treated as unrelated business taxable income for federal income tax purposes. If the Trustee is unable to obtain the required legal
opinion, it still may proceed with the borrowing or sale, or establish the reserve, if it determines that the failure to do so will be materially detrimental to the Unit holders considered as a whole.

The Trustee maintains a $1,000,000 cash reserve to provide liquidity to the Trust during any periods in which the Trust does not receive a
distribution from BP Alaska. See Item 7 in Part II below.

Irrevocability; Amendment of the Trust Agreement

The Trust Agreement and the Trust are irrevocable. No person has the power to terminate, revoke or change the Trust Agreement except as
described in the following paragraph and below under Termination of the Trust.

The Trust Agreement may be amended without a
vote of the Unit holders to cure an ambiguity, to correct or supplement any provision of the Trust Agreement that may be inconsistent with any other provision or to make any other provision with respect to matters arising under the Trust Agreement
that does not adversely affect the Unit holders. The Trust Agreement also may be amended with the approval of holders of a majority of the outstanding Units. However, no such amendment may alter the relative rights of Unit holders unless approved by
the affirmative vote of holders of 100% of the outstanding Units, nor may any amendment reduce or delay the distributions to the Unit holders, alter the voting rights of Unit holders or the number of Units in the Trust, or make certain other
changes, unless approved by the affirmative vote of holders of at least 80% of the outstanding Units and by the Trustee. The Trustee is required to consent to any amendment approved by the requisite vote of Unit holders unless the amendment affects
the Trustees rights, duties and immunities under the Trust Agreement. No amendment will be effective until the Trustee has received a ruling from the Internal Revenue Service or an opinion of counsel to the effect that such modification will
not adversely affect the classification of the Trust as a grantor trust for federal income tax purposes or cause the income from the Trust to be treated as unrelated business taxable income for federal income tax purposes.

Termination of the Trust

The Trust will terminate if either (a) holders of at least 60% of the outstanding Units vote to terminate the Trust or (b) the net
revenues from the Royalty Interest for two successive years are less than $1,000,000 per year (unless the net revenues during the two-year period have been materially and adversely affected by certain
extraordinary events).

Upon termination of the Trust, BP Alaska will have an option to purchase the Royalty Interest at a price equal to
the greater of (i) the fair market value of the Trust property as set forth in an opinion of an investment banking firm, commercial banking firm or other entity qualified to give an opinion as to the fair market value of the assets of the
Trust, or (ii) the number of outstanding Units multiplied by (a) the closing price of Units on the day of termination of the Trust on the stock exchange on which the Units are listed, or (b) if the Units are not listed on any stock
exchange but are traded in the over-the-counter market, the closing bid price on the day of termination of the Trust as quoted on the NASDAQ Stock Market. The purchase
must be for cash unless holders of 60% of the Units outstanding authorize the sale for non-cash consideration and the Trustee has received a ruling from the Internal Revenue Service or an opinion of counsel to
the effect that such non-cash sale will not adversely affect the classification of the Trust as a grantor trust for federal income tax purposes or cause the income from the Trust to be treated as
unrelated business taxable income for federal income tax purposes.

If BP Alaska does not exercise its option, the Trustee will sell the
Trust property on terms and conditions approved by the vote of holders of 60% of the outstanding Units, unless the Trustee determines that it is not practicable to submit the matter to a vote of the Unit holders and the sale is made at a price at
least equal to the fair market value of the Trust property as set forth in the opinion of the investment banking firm, commercial banking firm or other entity mentioned above and on terms and conditions deemed commercially reasonable by that firm.

The Trustee will distribute all available proceeds to the Unit holders after satisfying all existing liabilities of the Trust and
establishing adequate reserves for the payment of contingent liabilities.

Unit holders do not have the right under the Trust Agreement to
seek or secure any partition or distribution of the Royalty Interest or any other asset of the Trust or any accounting during the term of the Trust or during any period of liquidation and winding up.

Resignation or Removal of Trustee

The
Trustee may resign at any time or be removed with or without cause by vote of the holders of a majority of the outstanding Units at a meeting called and held in accordance with the Trust Agreement. A successor trustee may be appointed by BP Alaska
or, if the Trustee has been removed at a meeting of the Unit holders, the successor trustee may be appointed by the Unit holders at the meeting. Any successor trustee must be a corporation organized, doing business and authorized to exercise trust
powers under the laws of the United States, any state thereof or the District of Columbia, or a national banking association domiciled in the United States, in either case having a combined capital, surplus and undivided profits of at least
$50,000,000 and subject to supervision or examination by federal or state authorities. Unless the Trust already has a trustee that is a resident of or has a principal office in Delaware, any successor trustee must be a resident of Delaware or have a
principal office in Delaware. No resignation or removal of the Trustee will become effective until a successor trustee has accepted appointment.

Voting Rights of Unit Holders

Unit holders possess certain voting rights, but their voting rights are not comparable to those of shareholders of a corporation. For example,
there is no requirement for annual meetings of Unit holders or for periodic reelection of the Trustee.

A meeting of the Unit holders may
be called at any time to act with respect to any matter as to which the Trust Agreement authorizes the Unit holders to act. Any such meeting may be called by the Trustee in its discretion and will be called by the Trustee (i) as soon as
practicable after receipt of a written request by BP Alaska or a written request that sets forth in reasonable detail the action proposed to be taken at the meeting and is signed by holders of at least 25% of the outstanding Units or (ii) when
required by applicable laws or regulations or the New York Stock Exchange. The Trustee will give written notice of any meeting stating the time and place of the meeting and the matters to be acted on not more than 60 days nor fewer than 10 days
before the meeting to all Unit holders of record on a date not more than 60 days before the meeting at their addresses shown on the records of the Trust. All meetings of Unit holders are required to be held in Manhattan, New York City. Unit holders
are entitled to cast one vote on all matters coming before a meeting, in person or by proxy, for each Unit held on the record date for the meeting.

THE ROYALTY INTEREST

The Royalty Interest is a property right under Alaska law which burdens production, but there is no other security interest in the reserves or
production revenues assigned to it. The royalty payable to the Trust for each calendar quarter is the sum of the amounts obtained by multiplying Royalty Production for each day in the calendar quarter by the Per Barrel Royalty for that day. The
payment under the Royalty Interest for any calendar quarter may not be less than zero nor more than the aggregate value of the total production of oil and condensate from BP Alaskas working interest in the Prudhoe Bay Unit for the quarter, net
of the State of Alaska royalty and less the value of any applicable payments made to affiliates of BP Alaska.

Royalty Production

The Royalty Production for each day in a calendar quarter is 16.4246% of the lesser of (i) the first 90,000 barrels of the
actual average daily net production of crude oil and condensate for the quarter from the Prudhoe Bay (Permo-Triassic) Reservoir and saved and allocated to the oil and gas leases owned by BP Alaska in the Prudhoe Bay field as of
February 28, 1989 (the 1989 Working Interests), or (ii) the actual average daily net production of crude oil and condensate for the quarter from the 1989 Working Interests. The Royalty Production is based on oil produced
from the oil rim and condensate produced from the gas cap, but not on gas production or natural gas liquids production. The actual average daily net production of oil and condensate from the 1989 Working Interests for any calendar quarter is the
total production of oil and condensate for the quarter, net of the State of Alaska royalty, divided by the number of days in the quarter.

Per Barrel
Royalty

The Per Barrel Royalty for any day is the WTI Price for the day less the sum of (i) Chargeable Costs
multiplied by the Cost Adjustment Factor and (ii) Production Taxes.

##### Table of Contents

WTI Price

The WTI Price for any trading day is (i) the price (in dollars per barrel) for West Texas intermediate crude oil of standard
quality having a specific gravity of 40 API degrees for delivery at Cushing, Oklahoma (West Texas Intermediate) quoted for that trading day by whichever of The Wall Street Journal, Reuters, or Platts Oilgram Price Report, in that order,
publishes West Texas Intermediate price quotations for the trading day, or (ii) if the price of West Texas Intermediate is not published by one of those publications, the WTI Price will be the simple average of the daily mean prices (in dollars
per barrel) quoted for West Texas Intermediate by one major oil company, one petroleum broker and one petroleum trading company designated by BP Alaska, in each case unaffiliated with BP and having substantial U.S. operations, until published price
quotations are again available. If prices for West Texas Intermediate are not quoted so as to permit the calculation of the WTI Price, the price of West Texas Intermediate, for the purposes of calculating the WTI Price will be the price
of another light sweet domestic crude oil of standard quality designated by BP Alaska and approved by the Trustee, with appropriate allowance for transportation costs to the Gulf coast (or another appropriate location) to equilibrate its price to
the WTI Price. The WTI Price for any day which is not a trading day is the WTI Price for the preceding trading day.

Chargeable Costs

The Chargeable Costs per barrel of Royalty Production for each calendar year are fixed amounts specified in the Conveyance and do
not necessarily represent BP Alaskas actual costs of production. Chargeable Costs per barrel were $16.70 during 2012, $16.80 during 2013, $16.90 during 2014, $17.00 during 2015 and $17.10 during 2016. Chargeable Costs for 2017 and subsequent
years are shown in the following table:



|              |  |                           
|------------- |  | --------------------------
|Calendar
year |  | Chargeable Costsper barrel
|2017          |  | $17.20                    
|2018          |  | 20.00                     
|2019          |  | 23.75                     
|2020          |  | 26.50                     

After 2020, Chargeable Costs increase at a uniform rate of $2.75 per barrel per year.

Cost Adjustment Factor

The Cost
Adjustment Factor for a quarter is the ratio of the Consumer Price Index published for the most recently past February, May, August or November to 121.1 (the Consumer Price Index for January 1989). The Consumer Price Index is the
U.S. Consumer Price Index, all items and all urban consumers, U.S. city average (1982-84 equals 100), as first published, without seasonal adjustment, by the Bureau of Labor Statistics, Department of Labor,
without regard to subsequent revisions or corrections. If the average WTI Price for any calendar quarter falls to $18.00 or less, the Cost Adjustment Factor for that quarter will be the Cost Adjustment Factor for the immediately preceding quarter.
If the average WTI Price returns to more than $18.00 for a later quarter, adjustments to the Cost Adjustment Factor resume, but with an adjustment to the formula that excludes changes in the Consumer Price Index during the period that adjustments to
the Cost Adjustment Factor were suspended.

Production Taxes

Production Taxes are the sum of any severance taxes, excise taxes (including windfall profit tax, if any), sales taxes, value added
taxes or other similar or direct taxes imposed upon the reserves or production, delivery or sale of Royalty Production, computed at defined statutory rates.

On April 14, 2013, Alaskas legislature passed an oil-tax reform bill amending Alaskas
oil and gas production tax statutes, AS 43.55.10 et seq. (the Production Tax Statutes) with the aim of encouraging oil production and investment in Alaskas oil industry. On May 21, 2013, the Governor of Alaska
signed the bill into law as chapter 10 of the 2013 Session laws of Alaska (the Act). Among significant changes, the Act eliminated the monthly progressivity tax rate implemented by certain amendments to the Production Tax
Statutes in 2006 and 2007, increased the base rate from 25% to 35% and added a stair-step per-barrel tax credit for oil production. This tax credit is based on the gross value at the point of production per
barrel of taxable oil and may not reduce a producers tax liability below the minimum tax (which is a percentage, ranging from zero to 4%, of the gross value at the point of production of a producers taxable production during
the calendar year based on the average price per barrel for Alaska North Slope crude oil for sale on the United States West Coast for the year) under the Production Tax Statutes. These changes became effective on January 1, 2014.

On January 15, 2014, the Trustee executed a letter agreement with BP Alaska dated January 15, 2014 (the 2014 Letter
Agreement) regarding the implementation of the Act with respect to the Trust. Pursuant to the 2014 Letter Agreement, Production Taxes for the Trusts Royalty Production will equal the tax for the relevant quarter, minus the allowable
monthly stair-step per-barrel tax credits for the Royalty Production during that quarter. If there is a minimum tax-related limitation on the amount of the stair-step
per-barrel tax credits that could otherwise be claimed for any quarter during the year, any difference between that limitation as preliminarily determined on a quarterly basis and the actual limitation for the
entire year will be reflected in the payment to the Trust for the first quarter Royalty Production in the following year.

On July 6,
2015, BP Alaska and the Trustee signed a letter agreement (the 2014 Letter Agreement Amendment) amending the 2014 Letter Agreement to provide that if there is a minimum tax-related limitation on the amount of the stair-step per-barrel tax credits that could otherwise be claimed for any quarter during the year, any difference between that limitation as preliminarily determined on a quarterly basis and the actual limitation for the
entire year will be reflected in the payment to the Trust for the fourth quarter Royalty Production payment for such year rather than in the payment to the Trust for the first quarter Royalty Production in the following year.

The 2014 Letter Agreement Amendment became effective immediately. Thus, for 2016 any difference between the limitation as preliminarily
determined for the first through third quarters of 2016 and the actual limitation for 2016 will be reflected in the payment to the Trust for the fourth quarter of 2016, and not in the payment to the Trust for the first quarter of 2017.

Per Barrel Royalty Calculations

The
following table shows how the above-described factors interacted during the past five years to produce the average Per Barrel Royalty paid during the calendar years indicated. Royalty revenues are generally received on the fifteenth day of the month
following the end of the calendar quarter in which the related Royalty Production occurred. Revenues and expenses presented in the statement of cash earnings and distributions presented in Part II, Item 8 below are recorded on a modified cash basis
and, as a result, royalty revenues and distributions shown in such statements for any calendar year are attributable to BP Alaskas operations during the twelve-month period ended September 30 of that year. Dollar amounts in the table have
been rounded to two decimal places for presentation and do not reflect the precision of the actual calculations.

THE UNITS

Units

Each Unit represents an equal
undivided share of beneficial interest in the Trust. The Units do not represent an interest in or an obligation of BP Alaska, Standard Oil or any of their respective affiliates. Units are evidenced by transferable certificates issued by the Trustee.
Each Unit entitles its holder to the same rights as the holder of any other Unit. The Trust has no other authorized or outstanding class of securities.

Distributions of Income

BP Alaska makes quarterly payments to the Trust of the amounts due with respect to the Trusts Royalty Interest on the fifteenth day
following the end of each calendar quarter or, if the fifteenth is not a business day, on the next succeeding business day (the Quarterly Record Date). The Trustee pays all expenses of the Trust for each quarter on the Quarterly Record
Date to the extent possible, then distributes the excess, if any, of the cash received by the Trust over the Trusts expenses, net of any additions to or subtractions from the cash reserve established for the payment of estimated liabilities
(the Quarterly Distribution), to the persons in whose names the Units were registered at the close of business on the Quarterly Record Date.

The Trust Agreement requires the Trustee to pay the Quarterly Distribution to Unit holders on the fifth day after the Trustees receipt
of the amount paid by BP Alaska. Cash balances held by the Trustee for distribution to Unit holders are required to be invested in United States government or agency obligations secured by the full faith and credit of the United States
(Government Obligations) or, if Government Obligations that mature on the date of the distribution to Unit holders are not available, in repurchase agreements secured by Government Obligations with banks having capital, surplus and
undivided profits of $100,000,000 or more (which may include The Bank of New York Mellon). If time does not permit the Trustee to invest collected funds in Government Obligations or repurchase agreements, the Trustee may invest funds overnight in a
time deposit with a bank meeting the foregoing capital requirement (including The Bank of New York Mellon).

Reports to Unit Holders

After the end of each calendar year, the Trustee mails a report to the persons who held Units of record during the year containing information
to enable them to make the calculations necessary for federal and Alaska income tax purposes, including the calculation of any depletion or other deduction which may be available to them for the calendar year. In addition, after the end of each
calendar year the Trustee mails Unit holders an annual report containing a copy of this Form 10-K and certain other information required by the Trust Agreement.

Limited Liability of Unit Holders

The
Trust Agreement provides that the Unit holders are, to the full extent permitted by Delaware law, entitled to the same limitation of personal liability extended to stockholders of private corporations for profit under Delaware law.

Possible Divestiture of Units

The Trust
Agreement imposes no restrictions on nationality or other status of the persons eligible to hold Units. However, it provides that if at any time the Trust or the Trustee is named a party in any judicial or administrative proceeding seeking the
cancellation or forfeiture of any property in which the Trust has an interest because of the nationality, or any other status, of any one or more Unit holders, the Trustee may require each holder whose nationality or other status is an issue in the
proceeding to dispose of his Units to a party not of the nationality or other status at issue in the proceeding. If any holder fails to dispose of his Units within 30 days after receipt of notice from the Trustee to do so, the Trustee will redeem
any Units not so transferred within 90 days after the end of the 30-day period specified in the notice for a cash price equal to the fair market value of the Units. Units redeemed by the Trustee will be
cancelled.

##### Table of Contents

The Trustee may cause the Trust to borrow any amount required to redeem the Units. If the
purchase of Units from an ineligible holder by the Trustee would result in a non-exempt prohibited transaction under the Employee Retirement Income Security Act of 1970, or under the Internal
Revenue Code of 1986, the Units subject to the Trustees right of redemption will be purchased by BP Alaska or a designee of BP Alaska.

Issuance
of Additional Units

The Trust Agreement provides that BP Alaska or an affiliate from time to time may assign to the Trust additional
royalty interests meeting certain conditions and, upon satisfaction of various other conditions, the Trust may issue up to an additional 18,600,000 Units. BP Alaska has not conveyed any additional royalty interests to the Trust, and the Trust has
not issued any additional Units.

THE BP SUPPORT AGREEMENT

BP agreed to provide financial support to BP Alaska in meeting its payment obligations to the Trust in a Support Agreement dated
February 28, 1989 among BP, BP Alaska, Standard Oil and the Trust (the Support Agreement). Within 30 days after BP receives notice from the Trustee that the royalty payable with respect to the Royalty Interest or any other amount
payable by BP Alaska or Standard Oil has not been paid to the Trustee, BP will cause BP Alaska and Standard Oil to satisfy their respective payment obligations to the Trust and the Trustee under the Trust Agreement and the Conveyance, including
contributing to BP Alaska the funds necessary to make such payments. BP is required to make available to BP Alaska and Standard Oil such financial support as BP Alaska, Standard Oil or the Trustee may request in writing. Any Unit holder has the
unconditional right to institute suit against BP to enforce BPs obligations under the Support Agreement.

Neither BP nor BP Alaska
may transfer or assign its rights or obligations under the Support Agreement without the prior written consent of the Trustee, except that BP can arrange for its obligations to be performed by any of its affiliates so long as BP remains responsible
for ensuring that its obligations are performed in a timely manner.

BP Alaska may sell or transfer all or part of its working interest in
the Prudhoe Bay Unit, although such a transfer will not relieve BP of its responsibility to ensure that BP Alaskas payment obligations with respect to the Royalty Interest and under the Trust Agreement and the Conveyance are performed.

BP will be released from its obligation under the Support Agreement upon the sale or transfer of all or substantially all of BP Alaskas
working interest in the Prudhoe Bay Unit if the transferee agrees in writing to assume and be bound by BPs obligation under the Support Agreement. The transferees agreement to assume BPs obligations must be reasonably satisfactory
to the Trustee and the transferee must be an entity having a rating of its unsecured, unsupported long-term debt of at least A3 from Moodys Investors Service, Inc., a rating of at least A- from
Standard & Poors, or an equivalent rating from at least one nationally-recognized statistical rating organization (after giving effect to the sale or transfer and the assumption of all of BP Alaskas obligations under the
Conveyance and all of BPs obligations under the Support Agreement).

THE PRUDHOE BAY UNIT AND FIELD

Prudhoe Bay Unit Operation and Ownership

Since several oil companies besides BP Alaska hold acreage within the Prudhoe Bay field, as well as several contiguous oil fields, the Prudhoe
Bay Unit was established to optimize field development. Other owners of these fields include affiliates of Exxon Mobil Corporation, ConocoPhillips and Chevron Corporation. The Trusts Royalty Interest pertains only to production from the 1989
Working Interests in the Prudhoe Bay field and does not include production from the other oil fields included in the Prudhoe Bay Unit.

The operations of BP Alaska and the other working interest owners in the Prudhoe Bay Unit are governed by an agreement dated April 1,
1977 among the State of Alaska and the working interest owners establishing the Prudhoe Bay Unit (the Prudhoe Bay Unit Agreement) and an agreement dated April 1, 1977 among the working interest owners governing Prudhoe Bay Unit
operations (the Prudhoe Bay Unit Operating Agreement).

The Prudhoe Bay Unit Operating Agreement specifies the allocation of
production and costs to the working interest owners. It also defines operator responsibilities and voting requirements and is unusual in its establishment of separate participating areas for the gas cap and oil rim. Since July 1, 2000, BP
Alaska has been the sole operator of the Prudhoe Bay Unit.

The ownership of the Prudhoe Bay Unit by participating area as of
December 31, 2016 is shown in the following table:



|               |  |         |        |      |         |  |        |     
|-------------- |  | ------- | ------ | ---- | ------- |  | ------ | ----

|BP Alaska      |  |         | 26.36  | %(a) |         |  | 26.36  | %(b)
|Exxon Mobil    |  |         | 36.40  |      |         |  | 36.40  |     
|ConocoPhillips |  |         | 36.08  |      |         |  | 36.08  |     
|Chevron        |  |         | 1.16   |      |         |  | 1.16   |     
|Total          |  |         | 100.00 | %    |         |  | 100.00 | %   



|(a) | The Trusts share of oil production and condensate is computed based on BP Alaskas ownership interest 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) | The Trusts share of condensate production is computed based on BP Alaskas ownership interest in the gas cap participating area of 13.84% as of February 28, 1989. Subsequent 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. Under the terms of an Issues Resolution Agreement entered into by the Prudhoe Bay Unit owners
in October 1990, produced condensate (defined as the Original Condensate Reserve in the agreement) from the gas cap participating area was allocated to that participating area until a cumulative limit of 1,175 million barrels was reached. This
cumulative limit was reached in June 2014, and beginning at that time and continuing thereafter, the condensate is allocated to the oil rim participating area.

##### Table of Contents

If BP Alaska fails to pay any costs and expenses chargeable to BP Alaska under the Prudhoe Bay
Unit Operating Agreement and the production of oil and condensate is insufficient to pay such costs and expenses, the Royalty Interest is chargeable with a pro rata portion of such costs and expenses and is subject to the enforcement against it of
liens granted to the operators of the Prudhoe Bay Unit. However, in the Conveyance BP Alaska agreed to pay all costs and expenses chargeable to it and to ensure that no such costs and expenses will be chargeable against the Royalty Interest. The
Trust is not liable for any loss or liability incurred by BP Alaska or others attributable to BP Alaskas working interest in the Prudhoe Bay Unit or to the oil produced from it and BP Alaska has agreed to indemnify the Trust and hold it
harmless against any such impositions.

BP Alaska has the right to amend or terminate the Prudhoe Bay Unit Agreement, the Prudhoe Bay Unit
Operating Agreement and any leases or conveyances with respect to the 1989 Working Interests in the exercise of its reasonable and prudent business judgment without liability to the Trust. BP Alaska also has the right to sell or assign all or any
part of the 1989 Working Interests, so long as the sale or assignment is expressly made subject to the Royalty Interest and the terms and provisions of the Conveyance.

The Prudhoe Bay Field

The Prudhoe Bay
field is located on the North Slope of Alaska, 250 miles north of the Arctic Circle and 650 miles north of Anchorage. The Prudhoe Bay field extends approximately 12 miles by 27 miles and contains nearly 150,000 gross productive acres. Approximately
45% of the acreage within the field is subject to the Royalty Interest granted to the Trust by the Conveyance. The Prudhoe Bay field, which was discovered in 1968 by BP and others, has been in production since 1977 and is the largest producing oil
field in North America. As of December 31, 2016, approximately 11.72 billion barrels of oil and condensate had been produced from the Prudhoe Bay field.

Field Geology

The principal hydrocarbon
accumulations at Prudhoe Bay are in the Ivishak sandstone of the Sadlerochit Group at a depth of approximately 8,700 feet below sea level. The Ivishak is overlain by four minor reservoirs of varying extent which are designated the Put River, Eileen,
Sag River and Shublik (PESS) formations. Underlying the Sadlerochit Group are the oil-bearing Lisburne and Endicott formations. The net production allocated to the Royalty Interest pertains only to
the Ivishak and PESS formations, collectively known as the Prudhoe Bay (Permo-Triassic) Reservoir, and does not pertain to the Lisburne and Endicott formations.

The Ivishak sandstone was deposited, commencing some 250 million years ago, during the Permian and Triassic geologic periods. The
sediments in the Ivishak are composed of sandstone, conglomerate and shale which were deposited by a massive braided river and delta system that flowed from an ancient mountain system to the north. Oil was trapped in the Ivishak by a combination of
structural and stratigraphic trapping mechanisms.

Gross reservoir thickness is 550 feet, with a maximum oil column thickness of 425 feet.
The original oil column is bounded on the top by a gas-oil contact, originally at 8,575 feet below sea level across the main field, and on the bottom by an oil-water
contact at approximately 9,000 feet below sea level. A layer of heavy oil and tar overlays the oil-water contact in the main field and has an average thickness of around 40 feet.

##### Table of Contents

Oil Characteristics

The oil produced from the Prudhoe Bay (Permo-Triassic) Reservoir is a medium grade, low sulfur crude with an average specific gravity of 27 API
degrees. The gas cap composition is such that, upon surfacing, a liquid hydrocarbon phase, known as condensate, is formed.

The Royalty
Interest is based upon oil produced from the oil rim and condensate produced from the gas cap, but not upon gas production (which is currently uneconomic on a large scale) or natural gas liquids production stripped from gas produced.

Historical Production

Production from
the Prudhoe Bay field began on June 19, 1977, with the completion of the Trans-Alaska Pipeline System (TAPS). As of December 31, 2016 there were 1158 active producing oil wells, 31 gas reinjection wells, 187 water injection
wells and water and miscible gas injection wells in the Prudhoe Bay field. Production wells drilled in the field during the three years ended December 31, 2016 were: 50 in 2014, 56 in 2015 and 33 in 2016. These include new sidetrack completions
in existing wells. No exploratory drilling activities were conducted in the field during the three-year period. Production from the Prudhoe Bay field reached a peak in 1988 and has declined steadily since then. The average well production rate was
about 192 barrels per day in 2012, 188 barrels per day in 2013, 177 barrels per day in 2014, 170 barrels per day in 2015 and 171 barrels per day in 2016.

BP Alaskas share of the hydrocarbon liquids production from the Prudhoe Bay field includes oil, condensate and natural gas liquids.
Using the production allocation procedures from the Prudhoe Bay Unit Operating Agreement, the Prudhoe Bay fields total production and the net share of oil and condensate (net of State of Alaska royalty) allocated to the 1989 Working Interests
have been as follows during the past five years:

Collection and Transportation of Prudhoe Bay Oil

Raw crude oil produced from individual production wells located at well pads is diverted to flowlines (pipelines). The flowlines transport the
raw crude oil to one of six separation facilities (three on the



14

##### Table of Contents

western side of the Prudhoe Bay Unit and three on the eastern side) where the water and natural gas mixed with the raw crude are removed. The stabilized crude is then sent from the separation
facilities through two 34-inch diameter transit lines, one from each half of the Prudhoe Bay Unit, to Pump Station 1, the starting point for TAPS.

At Pump Station 1, Alyeska Pipeline Service Company, the operator of TAPS, meters the oil and pumps it in the
48-inch diameter pipeline to Valdez, almost 800 miles (1,288 km) to the south, where it is either loaded onto marine tankers or stored temporarily. It currently takes the oil about 16 days to make the trip
from the Prudhoe Bay Unit to Valdez, due to declining flows of oil from the North Slope. TAPS has a maximum daily average throughput of approximately 1.14 million barrels of oil; recently, however, the pipeline has been moving an average of
approximately 518 thousand barrels per day.

Following a partial shutdown of the eastern side of the Prudhoe Bay Unit which lasted
from August 7 until September 22, 2006, BP Alaska replaced approximately 16 miles of oil transit lines and has implemented new integrity management and corrosion monitoring practices that supplement or replace the practices that existed in
2006. BP Alaska states that its integrity management practices meet the requirements of 49 CFR 195.452 for pipeline integrity management in high consequence areas.

Reservoir Management

The Prudhoe Bay
field is a complex, combination-drive reservoir, with widely varying reservoir properties. Reservoir management involves directing field activities and projects to maximize the economic value of reserves.

Several different oil recovery mechanisms are currently active in the Prudhoe Bay field, including pressure depletion, gravity drainage/gas
cap expansion, water flooding and miscible gas flooding. Separate yet integrated reservoir management strategies have been developed for the areas affected by each of these recovery processes.

Reserve Estimates

Proved oil reserves
attributable to the 1989 Working Interests at December 31, 2016 are those quantities of oil which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from 2017 forward from
known reservoirs and under existing economic conditions, operating methods and government regulations. Estimates of proved reserves are inherently imprecise and subjective and are revised over time as additional data becomes available. Such
revisions often may be substantial. BP Alaskas reserve estimates and production assumptions and projections are predicated upon a reasonable estimate of the allocation of hydrocarbon liquids between oil and condensate according to the
procedures of the Prudhoe Bay Unit Operating Agreement. Oil and condensate are physically produced in a commingled stream of hydrocarbon liquids. The allocation of hydrocarbon liquids between the oil and condensate from the Prudhoe Bay field is a
theoretical calculation performed in accordance with procedures specified in the Prudhoe Bay Unit Operating Agreement. Under the terms of an Issues Resolution Agreement entered into by the Prudhoe Bay Unit owners in October 1990 (the Issuers
Resolution Agreement), the allocation procedures were adjusted to generally allocate condensate in a manner which approximates the anticipated decline in the production of oil until an agreed original condensate reserve of 1,175 million
barrels has been allocated to the working interest owners.

##### Table of Contents

By letter dated December 19, 2014, BP Alaska advised the Trustee that the portion of the
hydrocarbon liquids produced from the initial participating areas of the Prudhoe Bay Unit being allocated as condensate from the gas cap participating area was found to have reached on June 8, 2014 the agreed original condensate reserve of
1,175 million barrels allocated to the working interest owners. As a result, the portion of hydrocarbon liquids previously allocated as condensate to the gas cap participating area will be allocated to the oil rim participating area. This event
has had the effect of changing the calculation of the volume of Royalty Production subject to the Royalty Interest because 50.68% of hydrocarbon liquids allocated to the oil rim participating
area2 are counted for the purpose of calculating such volume, but only 13.84% of the hydrocarbon liquids are allocated to the gas cap participating area for such purpose.3 The end of the allocation to the gas cap participating area on June 8, 2014 meant that volumes of hydrocarbon liquids subject to the Royalty Interest for the second and third quarters of 2014
were greater than the volumes of Royalty Production initially reported by BP Alaska. The correction to the volumes of Royalty Production and the Royalty payments with respect to the Royalty Interest for such quarters were made in conjunction with
the scheduled Royalty payment in January 2015 for the quarter ended December 31, 2014. See Note 6 of Notes to Financial Statements below.

There is no precise method of forecasting the allocation of reserve volumes to the Trust. The Royalty Interest is not a working interest and
the Trust is not entitled to receive any specific volume of reserves from the 1989 Working Interests. The reserve volumes attributable to the 1989 Working Interests are estimated using an allocation of reserve volumes based on estimated future
production and the average WTI Price, and assume no future movement in the Consumer Price Index and no changes to the procedure for calculating Production Taxes. The estimated reserve volumes attributable to the Trust will vary if different
estimates of production, prices and other factors are used. Even if expected reservoir performance does not change, the estimated reserves, economic life, and future revenues attributable to the Trust may change significantly in the future. This may
result from changes in the WTI Price or from changes in other prescribed variables utilized in calculations defined by the Overriding Royalty Conveyance.

The reserves attributable to the 1989 Working Interests constitute only a part of the overall reserves in the Prudhoe Bay Unit. BP Alaska has
estimated that the proved reserves allocated to the Trust as of December 31, 2016 were 9.376 million barrels of oil and condensate, of which 9.204 million barrels are proved developed reserves4 and 0.172 million barrels are proved undeveloped reserves5. Proved reserves attributable to the Trust were reduced by approximately
13.676 million barrels during 2016 as a result of the significant reduction in the West Texas Intermediate price, forecast revisions and capital activities including drilling and well treatments. Additional information regarding changes in
estimated quantities of proved oil and condensate, proved developed reserves and proved undeveloped reserves is found below in Supplemental Reserve Information and Standardized Measure of Discounted Future Net Cash Flow Relating to Proved
Reserves (Unaudited) following the Notes to Financial Statements.

In all cases, the volumes are being progressed as a part of an adopted development plan that
calls for drilling of wells over an extended period of time given the magnitude of the development. BP has a historical record of completing comparable projects. There were no contributions to proved undeveloped reserves from extensions or
discoveries during 2016.Based on the 2016 twelve-month average WTI Price6of $42.75 per barrel, other economic parameters
prescribed by the Conveyance, and utilizing procedures specified in Financial Accounting Standards Board Accounting Standards Codification (FASB ASC) 932, Extractive Activities  Oil and Gas, BP Alaska calculated that as of
December 31, 2016 production of oil and condensate from the proved reserves allocated to the 1989 Working Interests will result in undiscounted estimated future cash flow to the Trust of $63.824 million, with a net present value of
estimated future cash flows at 10% discount of $59.186 million.

The internal controls applicable to the foregoing estimates of the
reserves allocated to the Trust are those employed by BP, which provides the information to the Trustee. BP Alaska has advised the Trustee that BPs vice president of segment reserves is the petroleum engineer primarily responsible for
overseeing the preparation of the reserves estimate. He has 30 years of diversified industry experience managing the governance and compliance of BPs reserves estimation since 2005. He is a past member of the Society of Petroleum Engineers Oil
and Gas Reserves Committee, a sitting member of the American Association of Petroleum Geologists Committee on Resource Evaluation and current chair of the bureau of the United Nations Economic Commission for Europe Expert Group on Resource
Classification. The Trust employs Miller and Lents, Ltd., an international oil and gas consulting firm, to conduct an annual review of BP Alaskas estimates of the proved reserves allocated to the Trust, estimated future net revenues to the
Trust, and the remaining period of economic production from the Prudhoe Bay field attributable to the Trust. All professionals assigned to the BP Prudhoe Bay Royalty Trust project are university graduates, with degrees in petroleum or chemical
engineering. Assigned staff members include licensed professional engineers with over 25 years of diversified experience. Work was supervised by a licensed professional engineer with more than 15 years of experience with the Trust. Acopy of
the February 15, 2017 report of Miller and Lents, Ltd.is filed as Exhibit 99 to this report.

BP Alaska has undertaken a
program of field-wide infrastructure renewal, pipeline replacement, and mechanical improvements to wells. As a consequence of these activities and their required downtime, and the natural production declines discussed above under Historical
Production, BP Alaskas net production of oil and condensate allocated to the Trust from proved reserves was less than 90,000 barrels per day on an annual basis in 2014, 2015 and 2016. BP Alaska anticipates that its average net production
of oil and condensate allocated to the Trust from proved reserves will be below 90,000 barrels per day on an annual average basis most future years. The occurrence of major gas sales could accelerate the decline in net production, due to the
consequent decline in reservoir pressure. See Item 1A, RISK FACTORS.

Based on the 2016 twelve-month average WTI Price of
$42.75 per barrel, current Production Taxes, and the Chargeable Costs adjusted as prescribed by the Overriding Royalty Conveyance, it is estimated that royalty payments to the Trust will continue through the year 2018, and would be zero in the
following year. Therefore, no proved reserves are currently attributed to the BP Prudhoe Bay Royalty Trust after that date. Even if expected reservoir performance does not change, the estimated reserves, economic life and future net revenues
attributable to the Trust may change significantly in the future. This may result from sustained periods of change in the WTI Price, the Production Tax or from changes in other prescribed variables utilized in calculations as defined by the
Overriding Royalty Conveyance.

##### Table of Contents

BP Alaska is under no obligation to make investments in development projects which would add
additional non-proved resources to proved reserves and cannot make such investments without the concurrence of the Prudhoe Bay Unit working interest owners. The Prudhoe Bay Unit working interest owners
regularly assess the technical and economic attractiveness of implementing projects to increase Prudhoe Bay Unit proved reserves. See Item 1A, RISK FACTORS, below.

In the event of changes in BP Alaskas current assumptions, oil and condensate recoveries may be reduced from the current estimates,
unless recovery projects other than those included in the current estimates are implemented.

INDUSTRY
CONDITIONS AND REGULATIONS

The production of oil and gas in Alaska is affected by many state and federal regulations with respect to
allowable rates of production, marketing, environmental matters and pricing. Future regulations could change allowable rates of production or the manner in which oil and gas operations may be lawfully conducted.

In general, BP Alaskas oil and gas activities are subject to existing federal, state and local laws and regulations relating to health,
safety, environmental quality and pollution control. BP Alaska believes that the equipment and facilities currently being used in its operations generally comply with the applicable legislation and regulations. During the past few years, numerous
environmental laws and regulations have taken effect at the federal, state and local levels. Oil and gas operations are subject to extensive federal and state regulation and to interruption or termination by governmental authorities due to
ecological and other considerations and in certain circumstances impose absolute liability upon lessees for the cost of cleaning up pollutants and for pollution damages resulting from their operations. Although BP Alaska has advised that the
existence of legislation and regulation has had no material adverse effect on BP Alaskas current method of operations, the effect of future legislation and regulations cannot be predicted.

Since the end of 2006, the corrosion monitoring and mitigation practices for the oil transit lines in the Prudhoe Bay Unit have been monitored
and reviewed by the U.S. Department of Transportation. The construction, testing, and commissioning of the new replacement oil transit lines have been inspected by DOT inspectors. The replacement lines have been constructed and are operated and
maintained in accordance with the requirements of the Pipeline Inspection, Protection, Enforcement and Safety Act of 2006 (the PIPES Act). The applicable requirements of the subsequent regulations of the PIPES Act began to be phased in
in 2012. See THE PRUDHOE BAY UNIT AND FIELD  Collection and Transportation of Prudhoe Bay Oil above.

CERTAIN TAX CONSIDERATIONS

The following is a summary of the principal tax consequences to Unit holders resulting from the
ownership and disposition of Units. The laws and regulations affecting these matters are complex, and are subject to change by future legislation or regulations or new interpretations by the Internal Revenue Service, state taxing authorities or the
courts. In addition, there may be differences of opinion as to the applicability or interpretation of present tax laws and regulations. BP Alaska and the Trust have not requested any rulings from the Internal Revenue Service with respect to the tax
treatment of the Units, and no assurance can be given that the Internal Revenue Service would concur with the statements below.

Unit
holders are urged to consult their tax advisors regarding the effects on their specific tax situations of owning and disposing of Units.

Federal Income Tax

Classification of the Trust

The following discussion assumes that the Trust is properly classified as a grantor trust under current law and is not an association taxable
as a corporation.

General Features of Grantor Trust Taxation

A grantor trust is not subject to tax, and its beneficiaries (the Unit holders in the case of the Trust) are considered for tax purposes to own
the assets of the trust directly. The Trust pays no federal income tax but files an information return reporting all items of income or deduction. If a court were to hold that the Trust is an association taxable as a corporation, the Trust would
incur substantial income tax liabilities in addition to its other expenses.

Taxation of Unit Holders

In computing his federal income tax liability, each Unit holder is required to take into account his share of all items of Trust income, gain,
loss, deduction, credit and tax preference, based on the Unit holders method of accounting. Consequently, it is possible that in any year a Unit holders share of the taxable income of the Trust may exceed the cash actually distributed to
him in that year. For example, if the Trustee should add to the reserve for the payment of Trust liabilities or repay money borrowed to satisfy debts of the Trust, the money used to replenish the reserve or to repay the loan is income to and must be
reported by the Unit holder, even though the money was not distributed to the Unit holder.

The Trust makes quarterly distributions to the
persons who held Units of record on each Quarterly Record Date. The terms of the Trust Agreement seek to assure to the extent practicable that income, expenses and deductions attributable to each distribution are reportable by the Unit holder who
receives the distribution.

The Trust allocates income and deductions to Unit holders based on record ownership at Quarterly Record Dates.
It is not known whether the Internal Revenue Service will accept the allocation based on this method.

Depletion Deductions

The owner of an economic interest in producing oil and gas properties is entitled to deduct an allowance for the greater of cost
depletion or (if otherwise allowable) percentage depletion on each such property. A Unit holders deduction for cost depletion in any year is calculated by multiplying the holders adjusted tax basis in his Units (generally his cost less
prior depletion deductions) by Royalty Production during the year and dividing that product by the sum of Royalty Production during the year and estimated remaining Royalty Production as of the end of the year. The allowance for percentage depletion
generally does not apply to interests in proven oil and gas properties that were transferred after December 31, 1974 and prior to October 12, 1990. The Omnibus Budget Reconciliation Act of 1990 repealed this rule for transfers occurring on
or after October 12, 1990. Unit holders who acquired their Units on or after that date may be permitted to deduct an allowance for percentage depletion if such deduction would otherwise exceed the allowable deduction for cost depletion. In
order to take percentage depletion, a Unit holder must qualify for the independent producer exemption contained in section 613A(c) of the Internal Revenue Code of 1986. Percentage depletion is based on the Unit holders gross income
from the Trust rather than on his adjusted basis in his Units. Any deduction for cost depletion or percentage depletion allowable to a Unit holder reduces his adjusted basis in his Units for purposes of computing subsequent depletion or gain or loss
on any subsequent disposition of Units.



19



---

##### Table of Contents

Unit holders must maintain records of their adjusted basis in their Units, make adjustments for
depletion deductions to such basis, and use the adjusted basis for the computation of gain or loss on the disposition of the Units.

Taxation of
Foreign Unit Holders

Generally, a holder of Units who is a nonresident alien individual or which is a foreign corporation (a
Foreign Taxpayer) is subject to tax on the gross income produced by the Royalty Interest at a rate equal to 30% (or at a lower treaty rate, if applicable). This tax is withheld by the Trustee and remitted directly to the United States
Treasury. A Foreign Taxpayer may elect to treat the income from the Royalty Interest as effectively connected with the conduct of a United States trade or business under Internal Revenue Code section 871 or section 882, or pursuant to any similar
provisions of applicable treaties. If a Foreign Taxpayer makes this election, it is entitled to claim all deductions with respect to such income, but a United States federal income tax return must be filed to claim such deductions. This election
once made is irrevocable unless an applicable treaty provides otherwise or unless the Secretary of the Treasury consents to a revocation.

Section 897 of the Internal Revenue Code and the Treasury Regulations thereunder treat the Trust as if it were a United States real
property holding corporation. Foreign holders owning more than five percent of the outstanding Units are subject to United States federal income tax on the gain on the disposition of their Units. Foreign Unit holders owning less than five percent of
the outstanding Units are not subject to United States federal income tax on the gain on the disposition of their Units, unless they have elected under Internal Revenue Code section 871 or section 882 to treat the income from the Royalty Interest as
effectively connected with the conduct of a United States trade or business.

If a Foreign Taxpayer is a corporation which made an
election under Internal Revenue Code section 882(d), the corporation would also be subject to a 30% tax under Internal Revenue Code section 884. This tax is imposed on U.S. branch profits of a foreign corporation that are not reinvested in the U.S.
trade or business. This tax is in addition to the tax on effectively connected income. The branch profits tax may be either reduced or eliminated by treaty.

Sale of Units

Generally, a Unit holder
will realize gain or loss on the sale or exchange of his Units measured by the difference between the amount realized on the sale or exchange and his adjusted basis for such Units. Gain on the sale of Units by a holder that is not a dealer with
respect to such Units will generally be treated as capital gain. However, pursuant to Internal Revenue Code section 1254, certain depletion deductions claimed with respect to the Units must be recaptured as ordinary income upon sale or disposition
of such interest.

Backup Withholding

A payor must withhold 28% of any reportable payment if the payee fails to furnish his taxpayer identification number (TIN) to the
payor in the required manner or if the Secretary of the Treasury notifies the payor that the TIN furnished by the payee is incorrect. Unit holders will avoid backup withholding by furnishing their correct TINs to the Trustee in the form required by
law.

##### Table of Contents

Widely Held Fixed Investment Trusts

The Trustee assumes that some Trust Units are held by a middleman, as such term is broadly defined in the U.S. Treasury Regulations (which
includes custodians, nominees, certain joint owners, and brokers holding an interest for a custodian in street name). Therefore, the Trustee considers the Trust to be a widely held fixed investment trust (WHFIT) for U.S. Federal income
tax purposes. The Bank of New York Mellon Trust Company, N.A. is the representative of the Trust that will provide tax information in accordance with applicable U.S. Treasury Regulations governing the information reporting requirements of the Trust
as a WHFIT. For information contact The Bank of New York Mellon Trust Company, N.A., Global Corporate Trust  Corporate Finance, 601 Travis Street, Floor 16, Houston, TX 77002, telephone number (713)
483-6020.

State Income Taxes

Unit holders may be required to report their share of income from the Trust to their state of residence or commercial domicile. However, only
corporate Unit holders will need to report their share of income to the State of Alaska. Alaska does not impose an income tax on individuals or estates and trusts. All Trust income is Alaska source income to corporate Unit holders and should be
reported accordingly.

Foreign Account Tax Compliance Act

Pursuant to the Foreign Account Tax Compliance Act (commonly referred to as FATCA), distributions from the Trust to foreign
financial institutions and certain other non-financial foreign entities may be subject to U.S. withholding taxes. Specifically, certain withholdable payments (including certain
royalties, interest and other gains or income from U.S. sources) made to a foreign financial institution or non-financial foreign entity will generally be subject to the withholding tax unless the foreign
financial institution or non-financial foreign entity complies with certain information reporting, withholding, identification, certification and related requirements imposed by FATCA. Foreign financial
institutions and non-financial foreign entities located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Foreign Unit holders
are encouraged to consult their own tax advisors regarding the possible implications of these withholding provisions on their investment in Trust Units.



|ITEM 1A. | RISK FACTORS

Owners of Units are exposed to risks and uncertainties that are particular
to their investment.



| |  |  | Royalty Production from the Prudhoe Bay field is projected to decline and will eventually cease.
| | - |  | ------------------------------------------------------------------------------------------------

The Prudhoe Bay field has been in production since 1977. Development of the field is largely completed and proved reserves are being depleted.
Production of oil and condensate from the field has been declining during recent years and the decline is expected to continue. As discussed above under the caption THE PRUDHOE BAY UNIT and FIELD  Reserve Estimates, Royalty
payments to the Trust, based on calculations using a 2016 WTI Price of $42.75 per barrel, among other prescribed variables, are projected to cease after 2018.

##### Table of Contents

Production estimates included in this report are based on economic conditions and production
forecasts as of the end of 2016, and also depend on various assumptions, projections and estimates which are continually revised and updated by BP Alaska. These revisions could result in material changes to the projected declines in production. It
is possible that economic production from the reserves allocated to the 1989 Working Interests could decline more quickly and end sooner than is currently projected.



| |  |  | Royalty payments by BP Alaska to the Trust are unpredictable, because they depend on Cushing, Oklahoma WTI spot prices, which are subject to volatility, and on the volume of production from the 1989 Working
Interests, which may vary from quarter to quarter in the future.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

WTI Prices, like prices in the global crude oil
market generally, are subject to periodic fluctuations and significant volatility. This was dramatically demonstrated by the steep decline in WTI Prices from more than $100 per barrel in June 2014 to around $27 dollars per barrel in early 2016. Even
before this plunge in price, what had been a general trend of WTI price increases had moderated as a result of increasing volumes of crude oil production from Canada and the Bakken shale formation, situated in the northwest portion of North Dakota
(and extending into Montana and portions of Canada), moving into the U.S. Midwest market. Oil production in the United States also surged owing, in part, to a dramatic increase in horizontal drilling and hydraulic fracturing, or fracking, and other
technological advances in oil detection and extraction.

This great increase in output from the U.S. helped lead to an oversupply in the
global crude market. As United States domestic production nearly doubled, the amount of oil imported into the United States declined. Countries like Saudi Arabia, Nigeria and Algeria that once sold their oil in the United States were forced to
compete for Asian markets, and such producers were forced to sell at lower prices.

While the global crude oil market became oversupplied,
global demand was declining, with the result that global oil prices dropped more than 70% from June 2014 through the middle of February 2016. As a result of this imbalance, U.S. production declined by over one million barrels per day by mid-2016 from a peak of 9.6 million barrels per day in June 2015 as U.S. oil companies discontinued most exploration and drilling operations.

The decline in global oil prices was halted in the first quarter of 2016 as the falling U.S. production and increased global demand led to
steadily increasing oil prices following the lows reached in early 2016. In June 2016, oil prices settled over $50 per barrel for the first time in almost a year on higher than expected draws on U.S. crude oil stockpiles and concerns about global
supply shortfalls following rebel attacks on Nigerias oil industry. Oil prices received additional support later in 2016 when OPEC members agreed in November to cut their total output by 1.2 million barrels per day during the first six
months of 2017. Eleven non-OPEC countries subsequently also agreed in December 2016 to curtail their production by 558,000 barrels per day for the first six months of the 2017. Among the non-OPEC producers, Russia, which produces the most crude oil of any country, conditionally agreed to reduce its production by 300,000 barrels a day. The full implementation of these agreements would reduce global
oil supply by nearly 2 percent.

As a result of these developments, by early February 2017, WTI and Brent prices had risen
approximately 100% from their lows a year earlier. In early February 2017, the International Energy Agency (IEA) reported that OPEC had achieved an initial compliance rate of 90 percent with respect to the November 2016 agreement.
According to the IEA, this initial reduction was one of the deepest in the history of OPEC initiatives to cut production. However, estimates of compliance by the non-OPEC nations with the oil output reduction
agreement have ranged between 40 and 50 per cent of the agreed upon cuts. Since there is no mechanism to enforce the agreements to reduce production, certain analysts have speculated that the OPEC and
non-OPEC producers may forego complying with the production cuts

if oil prices continue to rise. Even if there is substantial compliance with the terms of the agreements, these oil producing nations could rapidly increase production following the expiration of
the agreements. This in turn could lead to a surge of crude oil into the global markets in the second half of 2017, potentially exerting significant downward pressure on oil prices if there is not a countervailing increase in demand.

With respect to the U.S. market, the recent increases in oil prices have led to increases in inventories and U.S. oil rig productivity. Within
two months of the agreements of the OPEC and non-OPEC producers, U.S. shale oil production began to rise as higher prices made it profitable again for U.S. producers to restart their operations. According to
the U.S. Energy Information Administration (EIA), U.S. oil output increased in excess of 300,000 barrels per day from 8.70 million barrels per day for the week ended December 2, 2016 to more than 9 million barrels per day
for the week ended February 17, 2017. U.S. oil rig count for the week ended February 24, 2017 was reported to be the highest since October 2015.

While this increase in U.S. production could weigh upon oil prices, the EIA has noted that global demand for petroleum product is forecast to
grow at a faster rate in 2017 than in 2016 and that global oil markets currently appear to be more closely balanced than at any time in the recent past. According to the EIA, crude oil price volatility declined in December 2016 and continued
declining in January 2017. The EIA has also reported that monthly Brent crude oil prices have been trading in the narrowest range since May 2014 and that monthly WTI prices were trading in the narrowest range since December 2004. The EIA observed
that this narrow trading range suggests buyers and sellers have been nearing agreement that a price in the mid-$50 per barrel range may be sufficient to balance the oil market, with global demand growing
steadily and producers beginning to increase investments in new production. EIA forecasts that global oil inventories will decline by 0.2 million barrels per day in the first quarter of 2017. This projected decline contrasts with the estimated
1.5 million barrel per day increase in oil inventories during the same period in 2016.

The EIAs data and forecasts generally
suggest that the condition of the oil market is more robust in early 2017 than it was a year earlier, when excess production and slowing global demand created a glut in inventories that depressed crude oil prices. However, the EIA, like many
analysts, suggests that the oil market may be waiting to see how the balance between supply and demand will develop. If either the U.S. or the other oil producing nations produce too much, prices may decline once more. This would make it difficult
for U.S. producers to stay in the market, which might give the OPEC and non-OPEC nations an advantage with respect to market share. However, as evidenced by the agreements to reduce production, the non-U.S. oil producing nations also do not want lower prices, and such producers may prefer foregoing additional market share in the near term in order to support prices.

With specific reference to WTI prices, Cushing, Oklahoma, the delivery point for WTI futures contracts on the New York Mercantile Exchange,
has in prior periods occasionally become oversupplied due to new oil flows from Canada and the United States. Historically, this market had been reliant on high-cost rail and trucks to ship both crude oil stored at Cushing and production from Canada
and the Bakken shale formation to the Gulf Coast. These constraints on transportation of crude oil out of the U.S. Midwest market, together with the great increase in production in North America and the decades-long U.S. ban on crude oil exports,
helped to weigh down WTI spot prices for several years and kept the price of WTI crude oil at a historic discount to globally traded waterborne crudes such as Brent. In the past, WTI, which is generally a sweeter and lighter crude oil than Brent,
was more likely to trade at a premium to Brent.

##### Table of Contents

These transportation problems have been largely resolved. In May 2012, Enbridge, Inc. and
Enterprise Products Partners, joint owners of the Seaway crude oil pipeline, which links markets in the Houston area with oil storage facilities near Cushing, completed a project to reverse the flow direction of the Seaway Pipeline to run north to
south. Historically, pipelines have flowed from the Gulf Coast to Cushing. Following pump station additions and modifications, the capacity of the reversed Seaway Pipeline was increased to carry 400,000 barrels per day of crude oil to the Gulf
Coast. A Seaway Twin pipeline running parallel to the reversed Seaway Pipeline with a capacity to carry an additional 450,000 barrels a day came online in December 2014.

Other pipeline projects from the mid-continent to Gulf Coast refining centers have also helped reduce
the cost of transporting crude oil to refiners. This expansion of pipeline capacity from Cushing to Gulf Coast refineries relieved the mid-continent bottleneck by transporting the excessive inventories that
had built up in Cushing. However, the continued increase of U.S. oil production, additional pipelines bringing more oil from Colorado, North Dakota and Canada into Cushing and the reduction in global demand for crude oil resulted once again in
bringing inventories at Cushing to record levels in February 2016.

While inventories subsequently decreased by nearly 3% by December
2016, recent reports have again shown a sharp increase in storage. On February 15, 2017, the EIA reported that stockpiles of domestic crude oil inventories, excluding oil in the Strategic Petroleum Reserve, rose 9.5 million barrels to
total 518.1 million barrels for the week ended February 10. This was the sixth straight weekly increase in crude oil supplies and, according to the EIA, brought total inventories to a record weekly level, exceeding the previous record of
512.1 million barrels for the week ended April 29, 2016. Also, while the Seaway pipelines and other pipeline projects have helped significantly in facilitating transportation from Cushing to the Gulf Coast, closures of the Seaway pipelines
due to spills in October 2016 and early 2017 highlight the risk that prolonged shutdowns of these or other pipeline projects could also contribute to higher inventory levels, particularly if such shutdowns should coincide with increased volumes of
crude oil flowing into Cushing.

Nevertheless, the ability to ship crude oil out of Cushing via pipeline has allowed WTI and similar
inland U.S. crudes to compete directly with the higher-priced waterborne crude oils on the Gulf Coast (whose prices have historically closely followed Brent). This ability helped bring the price of WTI more in line with prices for other crude oils
trading on the global markets. After diverging in 2011 to a high of around $30 per barrel, with Brent the more expensive oil, the spread between WTI and Brent has gradually decreased as a result of the new crude pipeline construction and crude
pipeline flow reversals.

Other factors have the potential to further reduce the spread between the Brent price and the price of U.S.
domestic production. For example, in addition to the lack of pipeline capacity, as discussed above, the WTI/Brent spread has been influenced by the U.S. ban on crude oil exports introduced in the 1970s. That ban was lifted in December 2015 and
it was expected that the lifting of the export ban could help contribute to the use of WTI as a global benchmark. Although the U.S. continues to import approximately 10 times more oil than it exports (due, among other reasons, to U.S. refineries
having been designed to process much heavier crudes), the EIA reported that the U.S. exported 527,000 barrels per day in the first 11 months of 2016, compared to 465,000 barrels per day in 2015. While Canada, which was excluded from the export
restrictions, previously received most U.S. oil exports, the EIA has reported that since restrictions were lifted, oil exports to Canada have fallen by more than half and that U.S. crude oil is being shipped to countries in Western Europe, Asia, the
Carribean and South America. If OPEC and non-OPEC nations adhere to the production cuts agreed to in November 2016, U.S. producers may have an opportunity to gain access to additional international markets.

| |  |  | The amount and value of reserves attributable to the Trust, the estimated life of the Trust, estimates of future net revenues and estimates of the present value of future net revenues fluctuate based on the WTI
Price, among other factors. WTI Prices may be below thebreak-evenpoint for daily royalty calculations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As discussed above under THE ROYALTY INTEREST in Item 1, revenues to the Trust are calculated daily by BP Alaska using the WTI
price, production tax, and other variables as prescribed by the Conveyance applicable on that specific day. On January 1, 2017 the break-even WTI price (at which all taxes and prescribed deductions are equal to the WTI price) was
$32.99.7 The quarterly royalty payment by BP Alaska to the Trust is the sum of the individual revenues calculated each day during the quarter. In the event that one or more daily calculations
results in a negative amount, the total of such daily negative amounts during that calendar quarter would be subtracted from total daily positive amounts during such quarter to determine the royalty payment for such quarter, provided, that in no
event will any quarterly royalty payment be less than zero.

The estimated future net revenues and present value of estimated future net
revenues reported herein are calculated based on a single average WTI price, that being the average of 12 WTI values, each value representing the WTI price in effect on the first calendar day of the month for the 12 months prior to January 1,
2017. As a result, any single calculation of a calendar day will not reflect the value of the dividend paid to the Trust for any quarter, nor will it reflect the estimated future value of the Trust or the estimation of how long royalty payments to
the Trust will continue.

Based on the 2016 twelve-month average WTI Price of $42.75 per barrel, current Production Taxes, and the
Chargeable Costs adjusted as prescribed by the Overriding Royalty Conveyance, it is estimated that royalty payments to the Trust will continue through the year 2018, and would be zero in the following year. Therefore, no proved reserves are
currently attributed to the BP Prudhoe Bay Royalty Trust after that date. Even if expected reservoir performance does not change, the estimated reserves, economic life and future net revenues attributable to the Trust may change significantly in the
future as a result of sustained periods of change in the WTI Price, the Production Tax or from changes in other prescribed variables utilized in calculations as defined by the Overriding Royalty Conveyance. Such changes could result in the
termination of royalty payments prior to 2018.

While energy price forecasts are highly uncertain, EIA forecasts that Brent and WTI crude
oil prices will average $53 and $52 per barrel, respectively, in 2017 and $56 and $55 per barrel, respectively, in 2018. As discussed under THE PRUDHOE BAY UNIT AND FIELD  Reserve Estimates, the amount and value of reserves
attributable to the Trust and the estimated life of the Trust fluctuate based on changes to certain prescribed factors, including the WTI price. WTI prices at the level forecast by EIA should, subject to the effect of the other prescribed
variables, result in positive royalty payments to the Trust, if such prices actually constitute the 2017 or 2018 twelve-month average WTI Price (that is, the unweighted arithmetic average of the WTI price on the first day of each month during the
year). If such WTI Prices are in fact lower than the 2016 twelve-month average WTI Price of $42.75, this could result, subject to the effect of the other prescribed variables, in substantial decreases in the value and the estimated life of the Trust
as calculated for such periods compared to the 2016 calculations set forth under THE PRUDHOE BAY UNIT AND FIELD  Reserve Estimates.

However, future domestic and international events and conditions may produce wide swings in crude
oil prices over relatively short periods of time. Recent moves in crude oil prices have been affected by many factors. These include changes in demand due to variations in economic activity, increased efficiency, increased demand for other types of
fuel, strong production growth, new supplies from tight and shale resources, whether OPEC and other oil producing nations have been willing to intervene to stabilize oversupplied crude oil markets by cutting production or to take other measures in
order to preserve or expand market share, shifts in inventory management strategies by international oil companies, conservation measures by consumers, increasing effects of the oil futures market and other unpredictable political, geopolitical,
psychological and economic factors, such as developments with respect to the Iran nuclear deal, the strength or weakness of the U.S. dollar (the currency in which crude oil is quoted), how the policies of the new U.S. administration may influence
oil production and markets, expectations for global economic growth, political turmoil in North Africa and the Middle East and ongoing tensions in other regions of the world.

http://tonto.eia.doe.gov.

It is increasingly likely that the Trusts revenues in future periods also will be affected by
decreases in production from the 1989 Working Interests. BP Alaskas average net production of oil and condensate allocated to the Trust from proved reserves was less than 90,000 barrels per day on an annual basis during 2014, 2015 and 2016,
and the Trustee has been advised that BP Alaska expects that average net production allocated to the Trust from the proved reserves will be less than 90,000 barrels a day on an annual basis in future years. Unit holders thus are subject to the risk
that cash distributions with respect to their Units may vary widely from quarter to quarter.



| |  |  | 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.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------

In August 2006, BP Alaska shut down the eastern side of the Prudhoe Bay Unit following the discovery of unexpectedly severe corrosion and a
small spill from the oil transit line on that side of the Unit. Earlier, in March of 2006, BP had to temporarily shut down and commence the replacement of a three-mile segment of transit line on the western side of the Prudhoe Bay Unit following
discovery of a large oil spill.

BP Alaska completely replaced approximately 16 miles of transit lines on the eastern and western sides of
the Prudhoe Bay Unit and has implemented federally-required corrosion monitoring practices. However, the discovery of additional defects in Prudhoe Bay Unit oil flowlines and transit lines, and damage to or failures of separation facilities or other
critical equipment, could result in future shutdowns of oil production from all or portions of the Prudhoe Bay Unit and have an adverse effect on future royalty payments.



| |  |  | 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.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Trans-Alaska Pipeline System connects the North Slope oil fields to the southern port of Valdez, almost 800 miles away. It is the only way
that oil can be transported from the North Slope to market. The pipeline system crosses three mountain ranges, many rivers and streams and thaw-sensitive permafrost. It is susceptible along its length to damage from earthquakes, forest fires and
other natural disasters. The pipeline system also is vulnerable to failures of pipeline segments and pumping equipment, accidental

##### Table of Contents

damage and deliberate attacks. Recently, the pipeline has become susceptible to damage resulting from declining flows of oil from the North Slope. Slower flows cause the temperature of the oil in
the pipeline to cool faster, increasing the rate of deposit of wax, which coats pipe walls, hides corrosion and clogs sensors on smart pigs sent through the pipeline to detect it. Even lower flow rates projected in the future may lead to internal
damage caused by ice formation within the pipe and external damage from frost heaves under buried segments. Major upgrades to the pipeline may be required to counteract the effects of cooler oil temperature. If the pipeline or its pumping stations
should suffer major damage from natural or man-made causes, production from the Prudhoe Bay Unit could be shut in until the pipeline system can be repaired and restarted. Royalty payments to the Trust could be
halted or reduced by a material amount as a result of interruption to production from the Prudhoe Bay Unit.

In January 2011, TAPS was
shut down over two periods of several days each as a result of the discovery of a leak of crude oil in the basement of a booster pump building at Pump Station No. 1. See THE PRUDHOE BAY UNIT AND FIELD  Collection and Transportation
of Prudhoe Bay Oil in Item 1 for additional information.

In 2015, President Obama proposed designating 12 million of the
19 million acres of the Arctic National Wildlife Refuge (ANWR) as wilderness. The wilderness designation, which is the highest form of protection the federal government can give to public lands, would prohibit numerous activities,
such as drilling for oil and gas and road construction. This proposed designation, however, has not been implemented by Congress. In December 2016 the Obama administration also withdrew hundreds of millions of acres of federally owned land in the
Arctic and Atlantic Ocean from new offshore oil and gas drilling under the Outer Continental Shelf Lands Act. This action effectively banned new oil and gas drilling in nearly all U.S. waters in the Arctic Ocean. Although there is uncertainty
as to whether this withdrawal will survive under the Trump administration, this action, if implemented, together with the ANWR wilderness designation, if approved by Congress, could prohibit new oil production in much of Alaska.

As noted above, without more crude oil to be transported by TAPS, which, despite a modest increase in 2016, has had declining volumes over the
last decade, slower flows and freezing temperatures could eventually force the closure of the pipeline, making it impossible to transport oil from the North Slope to market. In a potentially significant development for Alaska and TAPS, a small
energy exploration company named Caelus Energy LLC announced in October 2016 that it had discovered oil in Smith Bay on Alaskas northern coast. The company reported that the field could hold as much as 6 billion barrels of oil and that it
expects to be able to recover between 1.8 to 2.4 billion barrels. If that amount is recoverable, it is estimated that the discovery would increase the amount of Alaskas statewide recoverable oil by approximately 80 percent. However,
due to the complexity and expense of the project and the length of the regulatory process, oil from the discovery is not expected to flow to TAPS until 2022.



| |  |  | Production from the 1989 Working Interests may be interrupted or discontinued by BP Alaska.
| | - |  | -------------------------------------------------------------------------------------------

BP Alaska has no obligation to continue production from the 1989 Working Interests or to maintain production at any level and may interrupt or
discontinue production at any time. The Trust does not have the right to take over operation of the 1989 Working Interests or share in any operating decisions by BP Alaska concerning the Prudhoe Bay Unit. The operation of the Prudhoe Bay Unit is
subject to normal operating hazards incident to the production and transportation of oil in Alaska. In the event of damage to the infrastructure, facilities and equipment in the Prudhoe Bay field which is covered by insurance, BP Alaska has no
obligation to use insurance proceeds to repair such damage and may elect to retain such proceeds and close damaged areas to production.

Construction of a gas pipeline from the North Slope of Alaska could accelerate the decline
in Royalty Production from the Prudhoe Bay field.

The construction of a natural gas pipeline to bring natural gas from the North
Slope could make it economical to extract natural gas from the Prudhoe Bay field and transport it to market. Currently, natural gas released by pumping oil is reinjected into the ground, which helps to maintain reservoir pressure and facilitates
extraction of oil from the field. Extraction of natural gas from the Prudhoe Bay field would lower reservoir pressure, although carbon dioxide stripped out of the gas could be reinjected and other methods could be employed to mitigate the reduction.
The lowering of the reservoir pressure could accelerate the decline in production from the 1989 Working Interests and the time at which royalty payments to the Trust would cease. Since the Trust is not entitled to any royalty payments with respect
to natural gas production from the 1989 Working Interests, the Unit holders would not realize any offsetting benefit from natural gas production from the Prudhoe Bay field.

Without a pipeline, extraction of natural gas from the Prudhoe Bay field on a large scale would not be economical. In October 2012,
ExxonMobil, ConocoPhillips, BP and Calgary-based TransCanada Corporation (TransCanada) notified the Alaska Governor that they had agreed on a plan to combine what were once two competing natural gas pipeline projects destined for the
continental U.S. into one project focused on export markets. This project contemplates building an 800-mile natural gas pipeline from the North Slope to a port on the southern coast of Alaska from which
liquified natural gas (LNG) would be exported to Asia. This project would also include natural gas processing facilities and a natural-gas export terminal.

In January 2014, it was announced that the state of Alaska would pursue becoming an equity partner in the Alaska natural gas pipeline project
and that ExxonMobil, BP, ConocoPhillips, TransCanada, Alaska Gasline Development Corporation (AGDC), and Alaskas commissioners of natural resources and revenue had signed a heads of agreement (HOA) for the Alaska LNG
Project. This established the commercial framework for the development of the natural gas pipeline from the North Slope to the south-central Alaska coast. The Nikiski area of the Kenai Peninsula was selected as the leading site for the LNG plant. In
September 2014, an application was filed with the Federal Energy Regulatory Commission (FERC) to begin a pre-filing process to begin preparatory work for an environmental impact statement for the
project. Earlier in 2014 an application was submitted to the U.S. Department of Energy for a license to export LNG. Pre-Front End Engineering and Design work, or
pre-FEED, also commenced in the summer of 2014. In November 2015, AGDC purchased TransCanadas 25% interest in the project.

In August 2016, ExxonMobil, BP and ConocoPhilips indicated that they did not currently wish to make further investments in the Alaska LNG
project. This decision followed a report, commissioned by ExxonMobil, BP and AGDC, by an energy consultancy firm stating the projects competitiveness ranks poorly under current market conditions. At the end of 2016, it was
announced that AGDC had concluded agreements with ExxonMobil, BP and ConocoPhillips to take over the leadership position in the Alaska LNG project. AGDC announced in December 2016 that all pre-FEED
deliverables and the FERC draft environmental and socioeconomic resource reports had been completed. According to AGDC, construction on the project could begin in 2019.

The LNG export project is expected to take six to eight years to complete due to the scale of construction and the number and complexity of
technical, legal, political and financial issues involved. It is anticipated that the cost of the project could be in excess of $65 billion. However, upon completion of the project, billions of dollars in natural gas currently stranded on the
North Slope could be transported.

| |  |  | The effect of any changes to the Alaska Production Tax Statutes on Per Barrel Royalty and Royalty Production from the Prudhoe Bay field is unpredictable.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------

As noted (see THE ROYALTY INTEREST  Production Taxes in Item 1 above), Alaskas Production Tax Statutes affect the
calculation of the Per Barrel Royalty. Among other changes to the Production Tax Statutes, the 2013 amendments added a stair-step per-barrel tax credit for oil production, provided that a producers tax
liability may not be reduced below the minimum tax. Since going into effect on January 1, 2014, the 2013 amendments have had the effect of reducing Production Taxes imposed on Royalty Production. Moreover, as a result of the low oil
price environment that began in mid-2014, Royalty Production has been subject to the minimum tax under the Production Tax Statutes since the first quarter of 2015. The reduction in Production Taxes has in part
offset the reduction in royalty payments that resulted from declining WTI prices.    Any changes to the Production Tax Statutes in the future may also impact the amount of Production Taxes and, in turn, the amount of royalty
payments. Whether or when any such changes may occur and the effect any such changes may have on the Per Barrel Royalty is unpredictable.

The Production Tax Statutes can also have an impact on Royalty Production from the Prudhoe Bay field. For example, the 2007 amendments to the
Production Tax Statutes (see THE ROYALTY INTEREST  Production Taxes in Item 1 above) may have accelerated the decline in production of oil and condensate from the Prudhoe Bay field to the extent that it caused BP Alaska and the
other owners of working interests in the Prudhoe Bay Unit to reduce or defer investment in oil production infrastructure renewal, well development and implementation of new technology due to uncompetitive returns on investment in Alaska. The 2007
amendments, in addition to increasing the basic oil production tax rate and the progressivity factor, also eliminated or reduced many deductions and credits permitted under the 2006 amendments to the Production Tax Statutes. Due in part to the 2007
amendments, BP Alaskas spending on production adding activity, adjusted for inflation, was flat to declining from 2008 through 2012. As noted under THE ROYALTY INTEREST  Production Taxes in Item 1 above, the 2013 amendments
to the Production Tax Statutes were intended to encourage oil production and investment in Alaskas oil industry by eliminating the monthly progressivity tax rate implemented by 2006 and 2007 amendments and adding a stair-step per-barrel tax credit for oil production. However, due to the low oil price environment that has prevailed for much of the time since the 2013 amendments went into effect, and since the Prudhoe Bay field is a mature
field, the impact of the 2013 amendments in terms of encouraging oil production and investment with respect to the Prudhoe Bay field is uncertain.



| |  |  | There are potential conflicts of interest between BP Alaska and the Trust that could affect the royalties paid to Unit holders.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------

The interests of BP Alaska and the Trust with respect to the Prudhoe Bay Unit could at times be different. The Per Barrel Royalty that BP
Alaska pays to the Trust is based on the WTI Price, Chargeable Costs and Production Taxes, all of which are amounts contractually defined in the Conveyance. The WTI Price does not necessarily correspond to the actual price realized by BP Alaska for
crude oil produced from the 1989 Working Interests, and Chargeable Costs and Production Taxes may not bear any relation to BP Alaskas actual costs of production and tax expenses. The actual per barrel profit realized by BP Alaska on the
Royalty Production may differ materially from the Per Barrel Royalty that it is required to pay to the Trust. It is possible under certain circumstances that the relationship between BP Alaskas actual per barrel revenues and costs could be
such that BP Alaska might determine to interrupt or discontinue production in whole or in part from the 1989 Working Interests even though a Per Barrel Royalty might otherwise be payable to the Trust under the Conveyance.

As of February 2, 2017, 21,400,000 Units were outstanding and were held by 303 holders of record. No
Units were purchased by the Trust or any affiliated purchaser during the year ended December 31, 2016.

Future payments of cash
distributions are dependent on such factors as prevailing WTI Prices, the relationship of the rate of change in the WTI Price to the rate of change in the Consumer Price Index, the Chargeable Costs, the rates of Production Taxes prevailing from time
to time, and the actual Royalty Production from the 1989 Working Interests. See THE ROYALTY INTEREST in Item 1.

|ITEM 7. | TRUSTEES DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | ----------------------------------------------------------------------------------

Liquidity
and Capital Resources

The Trust is a passive entity. The Trustees activities are limited to collecting and distributing the
revenues from the Royalty Interest and paying liabilities and expenses of the Trust. Generally, the Trust has no source of liquidity and no capital resources other than the revenue attributable to the Royalty Interest that it receives from time to
time. See the discussion under THE ROYALTY INTEREST in Item 1 for a description of the calculation of the Per Barrel Royalty, and the discussion under THE PRUDHOE BAY UNIT AND FIELD  Reserve Estimates in Item 1 for
information concerning the estimated future net revenues of the Trust. However, the Trust Agreement gives the Trustee power to borrow, establish a cash reserve, or dispose of all or part of the Trust property under limited circumstances. See the
discussion under THE TRUST  Sales of Royalty Interest; Borrowings and Reserves in Item 1.

---

##### Table of Contents

Since 1999, the Trustee has maintained a $1,000,000 cash reserve to provide liquidity to the
Trust during any future periods in which the Trust does not receive a distribution. The Trustee will draw funds from the cash reserve account during any quarter in which the quarterly distribution received by the Trust does not exceed the
liabilities and expenses of the Trust, and will replenish the reserve from future quarterly distributions, if any. The Trustee anticipates that it will keep this cash reserve program in place until termination of the Trust.

Amounts set aside for the cash reserve are invested by the Trustee in U.S. government or agency securities secured by the full faith and
credit of the United States. Interest income received by the Trust from the investment of the reserve fund is added to the distributions received from BP Alaska and paid to the Unit holders on each Quarterly Record Date.

Results of Operations

Relatively modest
changes in oil prices significantly affect the Trusts revenues and results of operations. Crude oil prices are subject to significant changes in response to fluctuations in the domestic and world supply and demand and other market conditions
as well as the world political situation as it affects OPEC and other producing countries. The effect of changing economic conditions on the demand and supply for energy throughout the world and future prices of oil cannot be accurately projected.

Royalty revenues are generally received on the Quarterly Record Date (generally the fifteenth day of the month) following the end of the
calendar quarter in which the related Royalty Production occurred. The Trustee, to the extent possible, pays all expenses of the Trust for each quarter on the Quarterly Record Date on which the revenues for the quarter are received. For the
statement of cash earnings and distributions, revenues and Trust expenses are recorded on a cash basis and, as a result, distributions to Unit holders in each calendar year ending December 31 are attributable to BP Alaskas operations
during the twelve-month period ended on the preceding September 30.

When BP Alaskas average net production of oil and condensate
per quarter from the 1989 Working Interests exceeds 90,000 barrels a day, the principal factors affecting the Trusts revenues and distributions to Unit holders are changes in WTI Prices, scheduled annual increases in Chargeable Costs, changes
in the Consumer Price Index and changes in Production Taxes. However, it is likely that the Trusts revenues in future periods also will be affected by increases and decreases in production from the 1989 Working Interests. BP Alaskas net
production of oil and condensate allocated to the Trust from proved reserves was less than 90,000 barrels per day on an annual basis during 2014, 2015 and 2016. The Trustee has been advised that BP Alaska expects that average net production
allocated to the Trust from the proved reserves will be less than 90,000 barrels a day on an annual basis in future years.

BP Alaska
estimates Royalty Production from the 1989 Working Interests for purposes of calculating quarterly royalty payments to the Trust because complete actual field production data for the preceding calendar quarter generally is not available by the
Quarterly Record Date. To the extent that average net production from the 1989 Working Interests is below 90,000 barrels per day, calculation by BP Alaska of actual Royalty Production data may result in revisions of prior Royalty Production
estimates. Revisions by BP Alaska of its Royalty Production calculations may result in quarterly royalty payments by BP Alaska which reflect adjustments for overpayments or underpayments of royalties with respect to prior quarters. Such adjustments,
if material, may adversely affect certain Unit holders who buy or sell Units between the Quarterly Record Dates for the Quarterly Distributions affected. See Note 8 of Notes to Financial Statements in Item 8. Because the annual statement of cash
earnings and distributions of the Trust is prepared on a modified cash basis, royalty revenues for the calendar year do not include the amounts of underpayments or overpayments affecting payments received during the fourth quarter of the year.

##### Table of Contents

During the years 2015 and 2016 and the period of 2017 up to the date of this report, WTI Prices
have been above the level necessary for the Trust to receive a Per Barrel Royalty. Whether the Trust will be entitled to future distributions during the remainder of 2017 will depend on WTI Prices prevailing during the remainder of the year.

As discussed above in Item 1A RISK FACTORS, it is anticipated that global oil prices could remain low for a significant
period. As also discussed above in Item 1A RISK FACTORS, on January 1, 2017, the break-even WTI price (the price at which all taxes and prescribed deductions are equal to the WTI price) for the Trust to receive a
positive Per Barrel Royalty with respect to a particular days production was $32.99. From the beginning of the first quarter of 2017 through February 22, 2017, the WTI crude oil spot price has fluctuated between a high of $54.06 per
barrel on February 21, 2017 and a low of $50.82 per barrel on January 10, 2017. The WTI crude oil spot price on February 22, 2016 was $53.59 per barrel. The quarterly royalty payment by BP Alaska to the Trust is the sum of
the individual revenues attributed to the Trust as calculated each day during the quarter. Any single calculation of a calendar day will not reflect the value of the dividend paid to the Trust for the quarter, nor will it reflect the estimated
future value of the Trust.However, if a low oil price environment should occur for a protracted period, quarterly royalty payments could decline significantly, and could in fact be zero.

2016 compared to 2015

As explained in
Note 2 of Notes to Financial Statements below, the financial statements of the Trust are prepared on a modified cash basis and differ from financial statements prepared in accordance with generally accepted accounting principles in that
(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 and (b) Trust expenses are recorded on an accrual basis. As a
consequence, Trust royalty revenues for the fiscal year are based on Royalty Production during the twelve months ended September 30 of the fiscal year.

Average WTI prices during the twelve months ended September 30, 2016 declined significantly compared to
the preceding twelve-month period. Nevertheless, because WTI prices began to rise after reaching lows early in the first quarter of 2016, the decline in WTI price for the period was substantially less than it was for the prior period, as indicated
in the chart below. WTI prices during this period ranged from an average high price of $46.22 during October 2015 to an average price of $45.18 during the last month of the period in September 2016. The lowest average monthly price for the period
was $30.32 in February 2016. The increase in the Consumer Price Index used to calculate the Cost Adjustment Factor, as well as the scheduled increase in Chargeable Costs from $17.00 in calendar 2015 to $17.10 in calendar 2016, resulted in the modest
increase in Adjusted Chargeable Costs during the twelve month ended September 30, 2016. The decrease in the average Per Barrel Royalty for the period

##### Table of Contents

resulted primarily from the decline in WTI prices. This decline was partially offset by the decline in Production Taxes. The decline in WTI prices resulted in Production Taxes for the fourth
quarter of 2015 and the first three quarters of 2016 being calculated on the basis of the minimum tax under the Act and the 2014 Letter Agreement. See Note 5 of Notes to Financial Statements in Item 8 below.

The increase in the average net production from the 1989 Working Interests between the two periods was due to ongoing development activity and
projects, which partially offset the naturally declining production rate from the Prudhoe Bay field and variance in the impacts of planned and unplanned downtime during the two reporting periods.

The period-to-period decreases
in royalty revenues, cash earnings and cash distributions are due to the significantly lower average WTI Prices that prevailed during 2016 compared to 2015. The decrease in administrative expenses reflects lower overall costs of supplies and
services and timing differences in accruals of expenses.

Average WTI prices during the twelve months ended September 30, 2015 declined significantly compared to
the preceding twelve-month period. Although the average WTI price for the second quarter of 2015 actually rose nearly 20% compared to the average WTI price for the first quarter of 2015, WTI prices during this period declined overall from an average
high price of $84.47 during October 2014 to an average price of $45.43 during the last month of the period in September 2015. The lowest average monthly price for the period was $43.19 in August 2015. The increase in the Consumer Price Index used to
calculate the Cost Adjustment Factor, as well as the scheduled increase in Chargeable Costs from $16.90 in calendar 2014 to $17.00 in calendar 2015, resulted in the modest increase in Adjusted Chargeable Costs during the twelve month ended
September 30, 2015. The decrease in the average Per Barrel Royalty for the period resulted primarily from the decline in WTI prices. This decline was partially offset by the decline in Production Taxes. The decline in WTI prices resulted in
Production Taxes for the second and third quarters of 2015 being calculated on the basis of the minimum tax under the Act and the 2014 Letter Agreement. See Note 5 of Notes to Financial Statements in Item 8 below.

##### Table of Contents

The increase in the average net production from the 1989 Working Interests between the two
periods reflects the BP Operating unit reaching the cumulative condensate limit of 1,175,000,000 barrels in the second quarter of 2014. Once the cumulative condensate limit was reached, the production associated with condensate became subject to the
Oil Rim Initial Participating Area royalty interest of 50.6848339% instead of the Gas Cap Participating Area Royalty Interest of 13.8398950%. Ongoing development activity and projects also contributed to this increase by partially offsetting the
naturally declining production rate from the Prudhoe Bay field and variance in the impacts of planned and unplanned downtime during the two reporting periods.

The period-to-period decreases
in royalty revenues, cash earnings and cash distributions are due to the significantly lower average WTI Prices that prevailed during 2015 compared to 2014. The decreases in royalty revenues, cash earnings and cash distributions were offset somewhat
by the increase in royalty interest received by the Trust as a result of the cumulative condensate limit being reached at the end of the second quarter of 2014 and the decrease in Production Taxes. The increase in administrative expenses reflects
higher overall costs of supplies and services and timing differences in accruals of expenses.



|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

The Trust is a passive
entity and except for the Trusts ability to borrow money as necessary to pay liabilities of the Trust that cannot be paid out of cash on hand, the Trust is prohibited from engaging in borrowing transactions. The Trust periodically holds
short-term investments acquired with funds held by the Trust pending distribution to Unit holders and funds held in reserve for the payment of Trust expenses and liabilities. Because of the short-term nature of these investments and limitations on
the types of investments which may be held by the Trust, the Trust is not subject to any material interest rate risk. The Trust does not engage in transactions in foreign currencies which could expose the Trust or Unit holders to any foreign
currency related market risk or invest in derivative financial instruments. It has no foreign operations and holds no long-term debt instruments.

Report of Independent Registered Public Accounting Firm

Trustee and Holders of Trust Units

BP Prudhoe Bay Royalty
Trust:

We have audited the accompanying statements of assets, liabilities, and trust corpus of BP Prudhoe Bay Royalty Trust (the Trust) as of
December 31, 2016 and 2015, and the related statements of cash earnings and distributions and changes in trust corpus for each of the years in the three-year period ended December 31, 2016. These
financial statements are the responsibility of The Bank of New York Mellon Trust Company, N.A., as the Trusts trustee (the Trustee). Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits 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 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 the Trustee, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for
our opinion.

As described in note 2 to the financial statements, these financial statements were prepared on the modified cash basis of accounting, which
is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America.

In our opinion, the financial
statements referred to above present fairly, in all material respects, the assets, liabilities, and trust corpus of the Trust as of December 31, 2016 and 2015, and its cash earnings and distributions and changes in trust corpus for each of the
years in the three-year period ended December 31, 2016, in conformity with the modified cash basis of accounting described in note 2.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Trusts internal control
over financial reporting as of December 31, 2016, based on criteria established in Internal Control  Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our
report dated March 1, 2017 expressed an unqualified opinion on the effectiveness of the Trusts internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

Trustee and Holders of Trust Units

BP Prudhoe Bay Royalty
Trust:

We have audited BP Prudhoe Bay Royalty Trusts internal control over financial reporting as of December 31, 2016, based
on criteria established in Internal Control  Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Bank of New York Mellon Trust Company, N.A., as the Trusts
trustee (the Trustee), 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 Item 9A Internal Control Over
Financial Reporting  Managements Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Trust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, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures
as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

The Trusts
internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with the modified cash
basis of accounting. The Trust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 Trust; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with the modified cash basis of accounting, and that receipts and
expenditures of the Trust are being made only in accordance with authorizations of the Trustee; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Trusts
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 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, BP Prudhoe Bay Royalty Trust maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control  Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the
Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States), the statements of assets, liabilities, and trust corpus of BP Prudhoe Bay Royalty Trust as of December 31, 2016 and 2015, and the related statements of cash earnings and distributions and changes in trust corpus for each of the years
in the three-year period ended December 31, 2016, and our report dated March 1, 2017 expressed an unqualified opinion on those financial statements.

BP Prudhoe Bay Royalty Trust

Notes to Financial Statements

(Prepared on a modified basis of cash receipts and disbursements)

December 31, 2016

(1)    Formation of the Trust and Organization

BP 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, as trustee, and BNY Mellon Trust of Delaware (successor to The Bank of New
York (Delaware)), as co-trustee. On December 15, 2010, The Bank of New York Mellon resigned as trustee and was replaced by The Bank of New York Mellon Trust Company, N.A., a national banking association,
as successor trustee (the 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 Trust Company, N.A. and BNY Mellon Trust of Delaware. 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 Trust Company, N.A. 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 (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 are less
than $1,000,000 per year (unless the net revenues during such period are materially and adversely affected by certain events).

Notes to Financial Statements

(Prepared on a modified basis of cash receipts and disbursements)

December 31, 2016



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 Accounting

The 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.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------

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, 2016 and 2015, and the modified cash earning and distributions and changes in Trust corpus for the years
ended December 31, 2016, 2015 and 2014. 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, 2016 and 2015, cash equivalents which represent the cash reserve consist of a Morgan Stanley ILF Treasury Fund.

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.

(3)    Royalty Interest

At inception in February 1989, the Royalty Interest held by the Trust had a carrying value of $535,000,000. In accordance with generally
accepted accounting principles, the Trust amortized the value of the Royalty Interest based on the units of production method. Such amortization was charged directly to the Trust corpus, and did not affect cash earnings. The daily rate for
amortization per net equivalent barrel of oil for the year ended December 31, 2010 was $0.38. In addition, the Trust periodically evaluated 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 (ASC) 360, Property, Plant, and Equipment. If the expected future undiscounted cash flows were less than the
carrying value, the Trust recognized impairment losses for the difference between the carrying value and the

estimated fair value of the Royalty Interest. By December 31, 2010, the Trust had recognized accumulated amortization of $359,473,000 and aggregate impairment write-downs of $175,527,000
reducing the carrying value of the Royalty Interest to zero.

(4)    Income Taxes

The 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 Tax

On April 14, 2013, Alaskas legislature passed an oil-tax reform bill amending Alaskas
oil and gas production tax statutes, AS 43.55.10 et seq. (the Production Tax Statutes) with the aim of encouraging oil production and investment in Alaskas oil industry. On May 21, 2013, the Governor of Alaska signed
the bill into law as chapter 10 of the 2013 Session laws of Alaska (the Act). Among significant changes, the Act eliminated the monthly progressivity tax rate implemented by certain amendments to the Production Tax Statutes
in 2006 and 2007, increased the base rate from 25% to 35% and added a stair-step per-barrel tax credit for oil production. This tax credit is based on the gross value at the point of production per barrel of
taxable oil and may not reduce a producers tax liability below the minimum tax (which is a percentage, ranging from zero to 4%, of the gross value at the point of production of a producers taxable production during the
calendar year based on the average price per barrel for Alaska North Slope crude oil for sale on the United States West Coast for the year) under the Production Tax Statutes. These changes became effective on January 1, 2014.

On January 15, 2014, the Trustee executed a letter agreement with BP Alaska dated January 15, 2014 (the 2014 Letter
Agreement) regarding the implementation of the Act with respect to the Trust. Pursuant to the 2014 Letter Agreement, Production Taxes for the Trusts Royalty Production will equal the tax for the relevant quarter, minus the allowable
monthly stair-step per-barrel tax credits for the Royalty Production during that quarter. If there is a minimum tax-related limitation on the amount of the stair-step
per-barrel tax credits that could otherwise be claimed for any quarter during the year, any difference between that limitation as preliminarily determined on a quarterly basis and the actual limitation for the
entire year will be reflected in the payment to the Trust for the first quarter Royalty Production in the following year.

On July 6,
2015, BP Alaska and the Trustee signed a letter agreement (the 2014 Letter Agreement Amendment) amending the 2014 Letter Agreement to provide that if there is a minimum tax-related limitation on the amount of the stair-step per-barrel tax credits that could otherwise be claimed for any quarter during the year, any difference between that limitation as preliminarily determined on a quarterly basis and the actual limitation for the
entire year will be reflected in the payment to the Trust for the fourth quarter Royalty Production payment for such year rather than in the payment to the Trust for the first quarter Royalty Production in the following year.

(6)    Royalty Revenue Adjustments

Certain royalty payments received by the Trust in 2016, 2015 and 2014 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). In addition, the payment received in January 2015 included an adjustment of
the royalty payment due with respect to the quarters ended June 30, 2014 and September 30, 2014. The underpayment was a result of the BP Operating unit reaching the cumulative condensate limit of 1,175,000,000 barrels as of June 8,
2014. Once the cumulative condensate limit had been reached the production associated with condensate is subject to the Oil Rim Initial Participating Area royalty interest of 50.6848339% instead of the Gas Cap Participating Area Royalty Interest of
13.8398950%. This allocation of the condensate production to the Oil Rim Initial Participating Interest remains in effect.

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 reflects the adoption
of Securities Exchange Act Release No. 59192, Modernization of Oil and Gas Reporting which became effective for financial statements for fiscal years ending on or after December 31, 2009.

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 Prudhoe Bay 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 2016 ($42.75 per barrel), 2015 ($50.28 per barrel) and 2014 ($94.99 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, 2016, 2015 and 2014, based on BP Alaskas latest reserve estimate at such times and the 12-month average WTI prices for 2016, 2015 and 2014, were estimated to be 9, 23 and 65 million barrels, respectively (of which 9, 22 and 62 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, 2016, 2015 and 2014, 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), based on the 12-month average WTI Prices for 2016, 2015 and 2014 of $42.75, $50.28 and $94.99 per barrel, respectively, scheduled chargeable costs in future years and production
taxes were as follows (in thousands):

|ITEM 9. | CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
|------- | ------------------------------------------------------------------------------------

There have been no changes in accountants and no disagreements with accountants on any matter of accounting principles or practices or
financial statement disclosures during the two fiscal years ended December 31, 2016.



|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of Disclosure Controls and Procedures

The Trustee has disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed by the Trust in the reports that it files or submits under the Exchange Act is recorded, processed, summarized
and reported, within the time periods specified in the SECs rules and forms. These controls and procedures include but are not limited to controls and procedures designed to ensure that information required to be disclosed by the Trust in the
reports that it files or submits under the Exchange Act is accumulated and communicated to the responsible trust officers of the Trustee to allow timely decisions regarding required disclosure.

Under the terms of the Trust Agreement and the Conveyance, BP Alaska has significant disclosure and reporting obligations to the Trust. BP
Alaska is required to provide the Trust such information concerning the Royalty Interest as the Trustee may need and to which BP Alaska has access to permit the Trust to comply with any reporting or disclosure obligations of the Trust pursuant to
applicable law and the requirements of any stock exchange on which the Units are issued. These reporting obligations include furnishing the Trust a report by February 28 of each year containing all information of a nature, of a standard and in
a form consistent with the requirements of the SEC respecting the inclusion of reserve and reserve valuation information in filings under the Exchange Act and with applicable accounting rules. The report is required to set forth, among other things,
BP Alaskas estimates of future net cash flows from proved reserves attributable to the Royalty Interest, the discounted present value of such proved reserves and the assumptions utilized in arriving at the estimates contained in the report.

In addition, the Conveyance gives the Trust certain rights to inspect the books and records of BP Alaska and discuss the affairs,
finances and accounts of BP Alaska relating to the 1989 Working Interests with representatives of BP Alaska; it also requires BP Alaska to provide the Trust with such other information as the Trustee may reasonably request from time to time and to
which BP Alaska has access.

The Trustees disclosure controls and procedures include ensuring that the Trust receives the
information and reports that BP Alaska is required to furnish to the Trust on a timely basis, that the appropriate responsible personnel of the Trustee examine such information and reports, and that information requested from and provided by BP
Alaska is included in the reports that the Trust files or submits under the Exchange Act.

As of the end of calendar year 2016, the trust
officers of the Trustee responsible for the administration of the Trust conducted an evaluation of the Trusts disclosure controls and procedures. Their evaluation considered, among other things, that the Trust Agreement and the Conveyance
impose enforceable legal obligations on BP Alaska, and that BP Alaska has provided the information required by those agreements and other information requested by the Trustee from time to time on a timely basis. The officers concluded that the
Trusts disclosure controls and procedures were effective, as of December 31, 2016.

Internal Control Over Financial Reporting

Managements Annual Report on Internal Control Over Financial Reporting.

The Bank of New York Mellon Trust Company, N.A., as Trustee of the Trust, is responsible for establishing and maintaining adequate internal
control over financial reporting, as such term is defined in Rule 13a-15(f) promulgated under the Exchange Act. The Trusts internal control over financial reporting is defined as a process designed by or
under the supervision of the Trustee to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Trusts financial statements for external reporting purposes in accordance with the modified cash
basis of accounting. The Trusts internal control over financial reporting includes policies and procedures that pertain to maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of
assets; provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with the modified cash basis of accounting, and that receipts and expenditures are being made only in
accordance with authorizations of the Trustee; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Trusts assets that could have a material effect on the Trusts
financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projection of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

The Trustee conducted an evaluation of the effectiveness of the Trusts internal control over financial reporting based
on the criteria established in Internal ControlIntegrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Based on the Trustees evaluation under
the COSO criteria, the Trustee concluded that the Trusts internal control over financial reporting was effective as of December 31, 2016.

The effectiveness of the Trusts internal control over financial reporting as of December 31, 2016 has been audited by KPMG LLP, an
independent registered public accounting firm, as stated in their report set forth in full above on page 40.

Changes in Internal
Control Over Financial Reporting.

There has not been any change in the Trusts internal control over financial reporting
identified in connection with the Trustees evaluation of the Trusts internal control over financial reporting that occurred during the Trusts fourth fiscal quarter that has materially affected, or is reasonably likely to materially
affect, the Trusts internal control over financial reporting.
