27-06-08 Oil sands and other unconventional energy resources would be included as reserves of oil and gas for the first time under new regulatory proposals.
The plan from the US Securities and Exchange Commission is a response to significant changes in the oil and gas industry in the past three decades.

Reserves reporting, used as a key measure by investors for assessing a company's long-term financial prospects, has been hugely sensitive in the past.
In addition to allowing previously excluded resources such as oil sands to be "classified" as oil and gas reserves, the proposals would allow companies to disclose their "probable" and "possible" reserves to investors, compared to only "proved" reserves currently.
