New US Accounting Pronouncements

Extractive Activities – Oil and Gas

In 2010, the FASB issued Extractive Activities – Oil and Gas, to align the reserve calculation and disclosure requirements with the requirements in the SEC Rule, Modernization of Oil and Gas Reporting Requirements. Effective December 31, 2009, but carried back to October 1, 2009, Talisman adopted this standard prospectively whereby yearly average commodity prices were used for purposes of calculating reserves. Previously, reserves had been calculated by reference to year-end commodity prices. Since 2009 yearly average commodity prices were higher than 2008 year-end prices, Talisman recorded an upward price revision of 77.1 mmboe to its reserves in the fourth quarter of 2009 and revised its DD&A rates accordingly.

The new standard permits companies to disclose information on probable and possible reserves. The new rules require companies to report their oil and gas reserves based on annual average prices determined by the prices in effect on the first day of each month, rather than year-end prices. In addition, the new standard adds, subject to certain exemptions, a 15% test to use as a minimum guideline for reporting ‘‘significant’’ reserves by geographic area, subject to various exemptions.

Fair Value Measurement

In 2010, the FASB issued an amendment to Fair Value Measurement and Disclosure. The new standard requires entities to disclose separately significant transfers in and out of level 1 and level 2 fair value measurements. Additionally, entities are required to present separately information about purchases, sales, issuances and settlements of level 3 fair value measurements. This amendment was adopted for Talisman’s 2010 reporting and did not have a material impact on the Company’s results or financial position.
