IFRS 13 Fair Value Measurement establishes a single framework for measuring fair value when required by IFRS standards. For real estate entities, this will replace the current fair value requirements in IAS 40 Investment Property. IFRS 13 defines fair value differently than international valuation standards and includes concepts like highest and best use that may require changes to valuation methods. It also significantly expands required disclosures around fair value measurements. Real estate entities will need to review processes for determining fair value and providing new disclosures to comply with IFRS 13, which takes effect for annual periods beginning on or after January 1, 2013.
