53 US GAAP reconciliation continued
Under US GAAP, environmental liabilities are discounted only where the timing and amounts of payments are fixed and reliably determinable.
Under IFRS, an expected loss is recognized immediately as a provision for an executory contract if the unavoidable costs of meeting the obligations
under the contract exceed the economic benefits expected to be received under it. Under US GAAP, an expected loss can only be recognized if the
contract is within the scope of authoritative literature that specifically provides for such accruals. The group has recognized losses under IFRS on certain
sales contracts with fixed-price ceilings which do not meet loss recognition criteria under US GAAP.
The adjustments to profit for the year and to BP shareholders’ equity to accord with US GAAP are summarized below.

(c) Oil and natural gas reserves differences
The group’s past practice was to use the UK accounting rules contained in the Statement of Recommended Practice ‘Accounting for Oil and Gas
Exploration, Development, Production and Decommissioning Activities’ (SORP) for estimating oil and natural gas reserves for accounting and reporting
purposes. These rules are different in certain respects from the corresponding SEC rules. In particular, the SEC requires the use of year-end prices,
whereas under SORP the group used long-term planning prices. The consequential difference in reserves volumes resulted in different charges for
depreciation, depletion and amortization (DD&A) between IFRS and US GAAP.
At the end of 2006, the group adopted the SEC rules for estimating oil and natural gas reserves for IFRS accounting and reporting purposes and the
charge for DD&A was calculated on this basis for the last three months of the year. This is a change in accounting estimate and the impact of the
change is applied prospectively. Differences in charges for DD&A between IFRS and US GAAP will continue due to the difference in net book values of
the underlying oil and natural gas properties.
The adjustments to profit for the year and to BP shareholders’ equity to accord with US GAAP are summarized below.

US GAAP requires the unit-of-production depreciation calculation to be based on development expenditure incurred to date and proved developed
reserves. Where production commences before all development wells are drilled, a portion of the development costs incurred to date is excluded from
the calculation. For the group’s portfolio of fields there is no material difference between the group’s charge for unit-of-production depreciation
determined on an IFRS basis and on a US GAAP basis.
