Wood Mackenzie has price assumptions that are distinct from our price forecasts. These price assumptions are used in our research products and asset valuations, and are updated each quarter. The assumptions are intended to reflect the average price needed to close M&A transactions between willing buyers and sellers. We monitor the asset market closely in our M&A and Corporate Services and are adjusting our assumptions to reflect the recent price falls. In many products we also include high and low prices for sensitivity purposes.
