• The following discussion should be read in conjunction with the consolidated financial statements and the related notes provided elsewhere in this Form 6-K and with the information, including the consolidated financial statements and related notes, for the year ended 31 December 2007 in BP p.l.c.’s Annual Report on Form 20-F for the year ended 31 December 2007.

• BP’s first quarter profit was $7,451 million, compared with $4,664 million a year ago, an increase of 60%. This included inventory holding gains of $863 million in the first quarter of 2008 compared with $220 million a year ago. See footnote (b) below for further information.

• Net cash provided by operating activities for the quarter was $10.9 billion compared with $8.0 billion a year ago.

• The effective tax rate for the quarter was 37%; the rate was 34% a year earlier.

• Net debt at the end of the quarter was $23.8 billion. The ratio of net debt to net debt plus equity was 19% compared with 20% a year ago. Net debt has been redefined as described on page 4.

• Capital expenditure, excluding acquisitions and asset exchanges, was $7.1 billion for the quarter. Total capital expenditure and acquisitions was $9.0 billion. Capital expenditure excluding acquisitions and asset exchanges, and excluding the accounting for our transaction with Husky, is expected to be around $21-22 billion for the year. Disposal proceeds were $0.3 billion for the quarter.

• The quarterly dividend, to be paid in June, is 13.525 cents per share ($0.8115 per ADS) compared with 10.325 cents per share a year ago, an increase of 31%. In sterling terms, the quarterly dividend is 6.830 pence per share, compared with 5.151 pence per share a year ago, a increase of 33%. During the quarter, the company repurchased 91 million of its own shares for cancellation at a cost of $1 billion.

• Non-GAAP information on fair value accounting effects in relation to Exploration and Production and Refining and Marketing is set out on page 10.

(a)	Profit attributable to BP shareholders.
(b)	Inventory holding gains and losses represent the difference between the cost of sales calculated using the average cost of supplies incurred during the year and the cost of sales calculated on the first-in first-out (“FIFO”) method. Under the FIFO method, which we use for IFRS reporting, the cost of inventory charged to the income statement is based upon the historic cost of acquisition or manufacture rather than the current replacement cost. In volatile energy markets, this can have a significant distorting effect on reported income. The amounts disclosed represent the difference between the charge to the income statement on a FIFO basis and the charge which would arise using average cost of supplies incurred during the period. For this purpose average cost of supplies incurred during the period is calculated by dividing the total cost of inventory purchased in the period by the number of barrels acquired. The amounts disclosed are not separately reflected in the financial statements as a gain or loss.
	Management believes this information is useful to illustrate to investors the fact that crude oil and product prices can vary significantly from period to period and that the impact on our reported result under IFRS can be significant. Inventory holding gains and losses vary from period to period due principally to changes in oil prices as well as changes to underlying inventory levels. In order for investors to understand the operating performance of the Group excluding the impact of oil price changes on the replacement of inventories, and to make comparisons of operating performance between reporting periods, BP’s Management believes it is helpful to disclose this information.
	Effective 1 January 2008, inventory holding gains and losses disclosed above include the associated tax effect. Previously the tax effect was not included. The comparative amount has been amended to the new basis.

The commentaries above and following should be read in conjunction with the cautionary statement on page 12.

EXPLORATION AND PRODUCTION (concluded)

The profit before interest and tax for the first quarter was $10,054 million, an increase of 59% over the first quarter of 2007. This included inventory holding losses of $18 million compared with inventory holding gains of $11 million in the first quarter of 2007. The result benefited from higher oil and gas realizations and a higher contribution from the gas marketing and trading and LNG businesses. This was partly offset by higher costs, primarily reflecting the impacts of higher depreciation and sector-specific inflation. The result also included higher income from equity-accounted entities, primarily from TNK-BP due to higher prices. In addition, BP’s share of income from TNK-BP benefited from the effect of lagged tax reference prices.

The result was after fair value losses on embedded derivatives of $684 million and restructuring charges of $44 million; and included a gain of $331 million relating to the release of certain provisions and a net gain of $21 million in respect of impairment and gains and losses on disposal. The corresponding quarter in 2007 included a net disposal gain of $605 million and fair value gains on embedded derivatives of $152 million.

Reported production for the quarter was 2,625mboe/d for subsidiaries and 1,288mboe/d for equity-accounted entities, compared with 2,660mboe/d and 1,252mboe/d respectively for the first quarter of 2007. For subsidiaries, this primarily reflects the ramp-up of production following the start-up of major projects in 2007, more than offset by the impact of lower entitlement in our production sharing agreements (PSAs). As previously indicated, if oil prices remain at $100 per barrel we expect 2008 total group production, including equity-accounted entities, to be broadly flat compared with 2007, with underlying production growth being offset by PSA entitlement impacts. We expect the quarterly phasing of underlying production during the year to reflect the normal seasonal effects associated with turnaround activity in the second and third quarters.

During the quarter, we had first production from the Mondo field within the Kizomba C development in Angola, where BP holds a 26.67% interest. Shortly after the end of the quarter, production commenced at Deep Water Gunashli on schedule; this completes the third and final phase of development of the Azeri-Chirag-Gunashli field (BP 34.1% and operator) in the Azerbaijan sector of the Caspian Sea. We had exploration success in Angola with the Portia discovery, in Egypt with the Satis discovery and in the North Sea with a discovery close to the Foinaven production facility.

On 31 March, we completed the deal with Husky Energy Inc. to create an integrated North American oil sands business by means of two separate joint ventures, one of which gives BP a 50% interest in Husky’s Sunrise field in Alberta, Canada. Capital expenditure of $2,848 million in respect of this transaction is reflected in the first quarter of 2008.

Shortly after the end of the quarter, we announced the Kodiak discovery in the deepwater Gulf of Mexico and, jointly with ConocoPhillips, announced that we have combined resources to start Denali — The Alaska Gas Pipeline.

REFINING AND MARKETING (concluded)

Refining and Marketing comprises Fuels Value Chains (FVC) and International Businesses. The FVCs include refineries, supply, logistics and marketing and trading activities. The International Businesses include lubricants, chemicals, LPG, aviation and marine fuels.

The profit before interest and tax for the first quarter was $2,573 million compared with $1,095 million for the same period last year. This included inventory holding gains of $1,324 million and $291 million respectively. The 2008 first-quarter result also included a net gain of $814 million in respect of impairment and gains and losses on disposal and a charge of $205 million in respect of restructuring costs. This compared with a charge of $179 million in respect of asset impairments a year ago. The gains on disposal in the first quarter of 2008 were primarily in respect of the contribution of the Toledo refinery into a joint venture with Husky Energy Inc., as part of the integrated North American oil sands deal completed on 31 March 2008.

Compared with the first quarter of 2007, our result reflected the adverse impacts of a significantly lower US refining margin environment and higher turnaround activities, primarily at the Carson refinery.

In the FVCs, we saw weaker US integrated margins, particularly on the West Coast, which more than offset improved performance in other regions. The average refining Global Indicator Margin (GIM) and BP’s actual refining margin for the first quarter were both significantly lower than those in the first quarter of 2007. Marketing margins were steady year on year, with slightly lower volumes versus a year ago.

Refining availability continued to improve for the sixth successive quarter, reaching 88.0% for the first quarter of 2008 compared with 81.6% in the first quarter of 2007. During the quarter, we completed the largest turnaround in the history of the Carson refinery, restored the Whiting refinery to its full clean fuel capability of 360mb/d in March and successfully restarted the sour crude distillation capacity at the Texas City refinery with most of its economic capability on track to be restored by mid-2008.

Refining throughput for the quarter was 2,166mb/d compared with 2,232mb/d for the same quarter last year. The lower throughput was mainly due to the turnaround activities at Carson.

Our International Businesses made a significant contribution to the segment result in both the first quarter and in the same period a year ago. We continued to make progress on reducing complexity and costs in the lubricants and aviation fuels businesses through portfolio simplification.

Operations at our new 900ktepa Zhuhai purified terephthalic acid (PTA) plant, which was successfully commissioned in early 2008, continued to improve with the production rate reaching over 90% in March.

On 17 March 2008, BP and Irving Oil entered into a memorandum of understanding to work together on the next phase of engineering, design, and feasibility for the proposed Eider Rock refinery in Saint John, New Brunswick, Canada. BP will contribute $40 million as its share of funding for this stage of the study and the two companies will also investigate the possibility of forming a joint venture to build the refinery should they decide to proceed.

Refining margins have improved to date in the second quarter but still remain significantly lower than the same quarter last year. The segment marketing businesses are likely to continue to experience pressure from the effects of higher product prices and a slowing of the OECD economies. We expect continued improvement in BP’s refining availability as the units at Texas City come onstream progressively during the rest of the year.

Other businesses and corporate comprises the Alternative Energy business, Shipping, the group’s aluminium asset, Treasury (which includes interest income on the group’s cash and cash equivalents), and corporate activities worldwide.

The profit before interest and tax for the first quarter was a loss of $193 million, compared with a loss of $97 million a year ago.

The quarter’s result included a net gain of $50 million in respect of impairment and gains and losses on disposal, fair value losses of $6 million on embedded derivatives and a $125 million charge for restructuring costs and other provisions. The corresponding quarter of 2007 included a net disposal gain of $31 million.

At the start of the year, our Alternative Energy business broadened its scope to include BP’s biofuels business, carbon capture and storage (CCS), clean coal and distributed energy, alongside the existing solar, wind, gas-fired power and hydrogen energy activities. In January, we announced our intention to pursue development options for a hydrogen power plant in Abu Dhabi with Abu Dhabi Future Energy Company (Masdar), through our Hydrogen Energy joint venture with Rio Tinto.

In addition, Alternative Energy and Dominion entered into a 50:50 joint venture to develop a wind farm in Indiana with a nameplate capacity of 300MW and we formed a 50:50 joint venture with NRG Energy, Inc. for the development and operation of a commercial wind farm, intended to be located in Texas and with a nameplate capacity of 150MW. Since the end of the quarter, we announced our intention to take a 50% stake in Tropical BioEnergia SA, a joint venture established by Brazilian companies Santelisa Vale and Maeda Group, which is constructing an ethanol refinery in Brazil and also plans to build a second refinery.

Non-GAAP information on fair value accounting effects

BP uses derivative instruments to manage the economic exposure relating to inventories above normal operating requirements of crude oil, natural gas and petroleum products as well as certain contracts to supply physical volumes at future dates. Under IFRS, these inventories and contracts are recorded at historic cost and on an accruals basis respectively. The related derivative instruments, however, are required to be recorded at fair value with gains and losses recognized in income because hedge accounting is either not permitted or not followed, principally due to the impracticality of effectiveness testing requirements. Therefore, measurement differences in relation to recognition of gains and losses occur. Gains and losses on these inventories and contracts are not recognized until the commodity is sold in a subsequent accounting period. Gains and losses on the related derivative commodity contracts are recognized in the income statement from the time the derivative commodity contract is entered into on a fair value basis using forward prices consistent with the contract maturity.

IFRS requires that inventory held for trading be recorded at its fair value using period end spot prices whereas any related derivative commodity instruments are required to be recorded at values based on forward prices consistent with the contract maturity. Depending on market conditions, these forward prices can be either higher or lower than spot prices resulting in measurement differences.

Contracts are entered into for pipelines and storage capacity which, under IFRS, are recorded on an accruals basis. These contracts are risk managed using a variety of derivative instruments which are fair valued under IFRS. This results in measurement differences in relation to recognition of gains and losses.

The way that BP manages the economic exposures described above, and measures performance internally, differs from the way these activities are measured under IFRS. BP calculates this difference by comparing the IFRS result with management’s internal measure of performance, under which the inventory and the supply and capacity contracts in question are valued based on fair value using relevant forward prices prevailing at the end of the period. We believe that disclosing management’s estimate of this difference provides useful information for investors because it enables investors to see the economic effect of these activities as a whole. The impact of fair value accounting effects, relative to management’s internal measure of performance, is shown in the table below and is non-GAAP.

The amounts shown in the tables above, in respect of comparative periods for the Refining and Marketing segment, have been revised from those disclosed previously. The revisions reflect changes in the basis for valuation of certain forward supply contracts to be consistent with the method used for other forward supply contracts when calculating management’s internal measure of performance. The changes to comparative figures are not material in relation to management’s internal measure of the Refining and Marketing segment’s performance. The changes have no impact on the results reported under IFRS.

Amendment to previous results announcement

On 29 April 2008, BP p.l.c. announced its unaudited group results for the three months ended 31 March 2008. Subsequent to making this announcement, management discovered that a refining inventory valuation error had led to the value of inventories being reported as $26,855 million in the group balance sheet instead of the correct figure of $26,588 million. The profit before interest and tax for the Refining and Marketing segment was stated to be $2,840 million instead of $2,573 million, a difference of $267 million. The group’s reported profit for the period attributable to BP shareholders, which is after tax, was stated to be $7,619 million instead of $7,451 million, a difference of $168 million. The group’s unaudited financial statements for the three months ended 31 March 2008 included in this Report on Form 6-K reflect the amended figures.

Following a review of the cause of the error in the refining inventory valuation in the first quarter, management is taking steps to improve the group’s internal control over this refining inventory valuation process. Management has also reviewed how this inventory valuation process operated in 2007 and has concluded that no similar errors were present.

FORWARD-LOOKING STATEMENTS

In order to utilize the ‘Safe Harbour’ provisions of the United States Private Securities Litigation Reform Act of 1995, BP is providing the following cautionary statement. This report on Form 6-K contains certain forward-looking statements with respect to capital expenditure, production, the restoration of refining economic capability, refining margins, likely continuing pressures on marketing businesses and expected improvements in refining availability. These statements may generally, but not always, be identified by the use of words such as ‘will’, ‘expects’, ‘is expected to’, ‘may’, ‘objective’, ‘believes’ or similar expressions. By their nature, forward looking statements involve risk and uncertainty and actual results may differ from those expressed in such statements depending on a variety of factors including the following: the timing of bringing new fields on stream; industry product supply; demand and pricing; operational problems; general economic conditions (including inflation); political stability and economic growth in relevant areas of the world; changes in laws and governmental regulations; exchange rate fluctuations; development and use of new technology; the success or otherwise non-success of partnering; the actions of competitors; natural disasters and severe adverse weather conditions; changes in public expectations and other changes to business conditions; wars and acts of terrorism or sabotage; and other factors discussed in this report. In addition to factors set forth elsewhere in this report, those set out above are important factors, although not exhaustive, that may cause actual results and developments to differ materially from those expressed or implied by these forward-looking statements. For more information you should refer to our Annual Report and Accounts 2007 and our 2007 Annual Report on Form 20-F filed with the US Securities and Exchange Commission.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — Basis of preparation

The interim financial information included in this Form 6-K has been prepared in accordance with IAS 34 ‘Interim Financial Reporting’.

The results for the interim periods are unaudited and in the opinion of management include all adjustments necessary for a fair presentation of the results for the periods presented. All such adjustments are of a normal recurring nature. The interim financial statements and notes included in this Report should be read in conjunction with the consolidated financial statements and related notes for the year ended 31 December 2007 included in BP’s Annual Report on Form 20-F filed with the Securities and Exchange Commission.

BP prepares its consolidated financial statements included within its Annual Report on Form 20-F on the basis of International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and IFRS as adopted by the European Union (EU). IFRS as adopted by the EU differs in certain respects from IFRS as issued by the IASB, however, the differences have no impact on the group’s consolidated financial statements for the periods presented. The financial information presented herein has been prepared in accordance with the accounting policies expected to be used in preparing the Annual Report on Form 20-F for the year ended 31 December 2008, which do not differ significantly from those used in the Annual Report on Form 20-F for the year ended 31 December 2007.

Note 2 — Resegmention and other changes to comparatives

(a) Resegmentation

On 11 October 2007, we announced our intention to simplify the organizational structure of BP. From 1 January 2008, there are only two business segments — Exploration and Production and Refining and Marketing. A separate business, Alternative Energy, handles BP’s low-carbon businesses and future growth options outside oil and gas. This includes solar, wind, gas-fired power, hydrogen, biofuels and coal conversion.

As a result, and with effect from 1 January 2008:

• The Gas, Power and Renewables segment ceased to report separately.

• The natural gas liquids (NGLs), liquefied natural gas and gas and power marketing and trading businesses were transferred from the Gas, Power and Renewables segment to the Exploration and Production segment.

• The Alternative Energy business was transferred from the Gas, Power and Renewables segment to Other businesses and corporate.

• The Emerging Consumers Marketing Unit was transferred from Refining and Marketing to Alternative Energy.

• The Biofuels business was transferred from Refining and Marketing to Alternative Energy.

• The Shipping business was transferred from Refining and Marketing to Other businesses and corporate.

As a result of the transfers identified above, Other businesses and corporate has been redefined. It now consists of the Alternative Energy business, Shipping, the group’s aluminium asset, Treasury (which includes interest income on the group’s cash and cash equivalents) and corporate activities worldwide.

(b) Revised income statement presentation

We have implemented a minor change in the presentation of the group income statement whereby the unwinding of the discount on provisions and on other payables is now included within finance costs. Previously this was included within other finance income or expense. This line item has now been renamed net finance income or expense relating to pensions and other post-retirement benefits. This change does not affect profit before interest and taxation, profit before taxation or profit for the period. The financial information for the comparative period shows the revised presentation, as set out below.

(c) Revised definition of net debt

Net debt and net debt ratio are non GAAP Measures. We believe that these measures provide useful information to investors. Net debt enables investors to see the economic effect of gross debt, related hedges and cash and cash equivalents in total. The net debt ratio enables investors to see how significant net debt is relative to equity from shareholders. Net debt has been redefined to include the fair value of associated derivative financial instruments that are used to hedge foreign exchange and interest rate risks relating to finance debt, for which hedge accounting is claimed. The derivatives are reported on the balance sheet within the headings ‘Derivative financial instruments’. Amounts for comparative periods are presented on a consistent basis.

Note 3 — Significant transaction in the period

In December 2007, BP signed a memorandum of understanding with Husky Energy Inc. to form an integrated North American oil sands business. The transaction was completed on 31 March 2008. In the US, BP contributed its Toledo refinery to a jointly controlled entity to which Husky contributed $250 million cash and a payable of $2,483 million. In Canada, Husky contributed its Sunrise field to a second jointly controlled entity, with BP contributing $250 million in cash and a payable of $2,290 million. The Toledo refinery assets and associated liabilities were classified as a disposal group held for sale at 31 December 2007.

Both jointly controlled entities are owned 50:50 by BP and Husky and are accounted for using the equity method.

As a result of the transaction, the items detailed below are included in the financial statements for the first quarter of 2008.
