South Korea's Financial Services Commission has finalized an amendment to K-IFRS requiring companies that account for land under the cost model to disclose its officially assessed value in the financial statement notes. The requirement applies from annual financial statements ending Dec. 31, 2026, with comparative information presented retrospectively. The disclosure covers land for which an officially assessed value is calculated and published under South Korea's real estate price disclosure law. It excludes overseas land, land without such a value, land measured under the revaluation model, and land classified as inventory or investment property. Companies must use the latest officially assessed value available under the law and disclose its reference date. The value is not fair value under K-IFRS and may differ because of its purpose, methodology and measurement date.
