Aon Thailand’s Valuation Trends is a biennial study that examines the assumptions and experiences of retirement plans under the International Accounting Standard 19 (IAS 19), Financial Accounting Standards Board (FASB) Accounting Standards Codification 715 (ASC 715) (formerly FASB Statements 87, 88, 106, 132 and 158), and Thai Accounting Standards (TAS 19).

The International Financial Reporting Standards (IFRS) and FASB requires companies to estimate the value of the employee benefit liabilities, while the IAS 19, TAS 19 and ASC 715 sets the rules of the determination of assumptions and reporting of these liabilities.

The main objective of this report is to provide a snapshot around the changes in financial and demographic assumptions used to value the liabilities and their actual experience. This study is conducted by gathering assumptions and disclosures used by over 280 employers over the 2019 financial year-end. Majority of the covered companies have financial years ending December 31, but we have also included those with financial years ending March to December 2019.
