BP Fourth Quarter 2006 Trading Update

This trading update is aimed at providing estimates regarding revenue and trading conditions experienced by BP in the fourth quarter ending December 31, 2006. The fourth quarter margin, price, realisation, cost, production and other data referred to below are currently provisional, some being drawn from figures applicable to the first month or so of the quarter. All such data are subject to change and may differ quite considerably from the final numbers that will be reported on February 6, 2007. In particular, data is not available at this time that would allow quantification of potential IFRS fair value accounting gains or charges, or of any potential consolidation adjustment. This trading update is produced in order to provide greater disclosure to investors and potential investors of currently expected outcomes, and to ensure that they all receive equal access to the same information at the same time.

Overall BP production in 4Q'06 is expected to be around 3,820 mboed. Excluding volumes from TNK-BP operations, production in 4Q'06 is expected to be around 2,890 mboed, slightly higher than in 3Q'06. The recovery from the summer maintenance season (primarily in the North Sea and Alaska) and continued ramp up of new projects in Azerbaijan and North Africa is expected to be partly offset by weather related delays to Alaskan loadings, unusually low seasonal gas demand, OPEC quota restrictions, and reduced entitlements under Production Sharing Contracts. BP's net share of production from TNK-BP is expected to be approximately 930 mboed, versus 948 mboed in 3Q'06, with the reduction reflecting the impact of divestments. Relative to 3Q'06, the TNK-BP result is expected to be adversely affected by an incremental tax lag of around $300m, and the absence in 4Q'06 of the gain on divestment which amounted to around $0.9bn in 3Q'06.

Refining Global Indicator Margin*	7.60	6.28	12.59	8.40	6.30

* The Refining Global Indicator Margin (GIM) is a generic indicator. Actual margins realised by BP may vary significantly due to a variety of factors, including specific refinery configurations, crude slate and operating practices.

The fourth quarter's Global Indicator Margin (GIM) was lower than in both 3Q'06 and 4Q'05. Marketing margins are also expected to be significantly lower than in both 3Q'06 and 4Q'05. The costs of turnaround activity are expected to be higher than in either of such prior periods. A significant negative impact related to IFRS fair value accounting is expected in 4Q'06, compared to a significant positive impact in 3Q'06. The aggregate impact of IFRS fair value accounting on the full year 2006 results is not expected to be material.

Gas, Power and Renewables

GP&R margins for the quarter are expected to be significantly lower than 3Q'06, due to weaker NGL, gas and power trading margins. Lower margins are expected to be largely offset by a positive impact related to IFRS fair value accounting. The aggregate impact of IFRS fair value accounting on the full year 2006 results is not expected to be material.

Other Businesses and Corporate

The 4Q'06 charge in Other Businesses and Corporate is expected to be in line with guidance given in our February 2006 Strategy Presentation for an annual charge of $900m +/- $200m.

Identified Non-Operating Items (NOIs)

Aggregate non-operating items in 4Q'06 are expected to amount to a small gain.

Interest Expense

The total consolidated interest charge is expected to be around $150m.

Tax Rate

The effective tax rate for the quarter is expected to be around 25%, reflecting a number of favourable Q4 items.

Gearing

Gearing for the quarter is expected to be around 21%, an increase from the 3Q'06 level of 17% due to the phasing of tax payments and normal seasonal working capital movements.

Distributions to Shareholders

During the quarter the company bought back 310 million shares for a total consideration of $3.5bn. Shares outstanding at December 29th 2006, excluding treasury shares, were 19,510 million. As in previous quarters, BP has entered into an arrangement that allows the share buy back programme to be continued during the closed period which commenced on December 31st. The 4Q'06 dividend of 9.825 cents per share announced at the time of our 3Q'06 results was paid in December. The dividend to be paid in 1Q'07 will be announced on February 6th, in conjunction with our 4Q'06 Stock Exchange Announcement.

Rules of Thumb

Important note: The rules of thumb shown below were provided with BP's strategy update on February 7th, 2006 and were intended to give directional indicators of the impact of changes in the trading environment relative to that of 2005 on BP's 2006 full year pre-tax results. These rules of thumb are approximate. Especially over short periods, changes in prices, margins, differentials, seasonal demand patterns and other factors can be material. Particular differences may arise due to higher government shares of Exploration and Production revenues in some jurisdictions at current price levels, as well as from variations between the refining Global Indicator Margin (GIM) and BP's realised refining margins due to crude price levels and differentials, product price movements and other factors. The GIM rule of thumb reflects the sensitivity to the overall group to changes in refining margins. Many other factors will affect BP's earnings quarter by quarter. Actual results in individual quarters may therefore differ significantly from the estimates implied by the application of these rules of thumb.
