An entity shall include the cash flows associated with [value beyond proven and probable reserves](https://asc.understandingaccounting.org/glossary/v/#value-beyond-proven-and-probable-reserves "Value beyond proven and probable reserves is the economic value that exists in a mining asset beyond the value attributable to proven and probable reserves. The distinction between the categories of reserves relates to the level of geological evidence and, therefore, confidence in the reserve estimates.") in estimates of future cash flows (both undiscounted and discounted) used for determining whether a mining asset is impaired under paragraphs

. Estimated cash flows also shall include the estimated cash outflows required to develop and extract the value beyond proven and probable reserves.

An entity shall consider the effects of anticipated fluctuations in the market price of minerals when estimating future cash flows (both undiscounted and discounted) used for determining whether a mining asset is impaired under the Impairment or Disposal of Long-Lived Assets Subsections of Subtopic 360-10. Estimates of those effects shall be consistent with estimates of a market participant. Generally, an entity shall consider all available information including current prices, historical averages, and forward pricing curves. Those marketplace assumptions typically shall be consistent with an entity's operating plans and financial projections underlying other aspects of the impairment analysis (for example, amount and timing of production). It generally would be inappropriate for an entity to use a single factor, such as the current price or a historical average, as a surrogate for estimating future prices without considering other information that a market participant would consider.
