Investments in convertible bonds are classified under level 3 in the fair value hierarchy, with the fair value estimated based on the third-party appraisal report using the expected credit loss model. Key inputs and parameters include probability of default which is the likelihood that a borrower will default on a credit obligation over a specific time horizon, and loss given default which is an estimate of the loss from a transaction given that a default occurs. Certain equity securities and available-for-sale debt securities are classified under level 2 in the fair value hierarchy, with the fair value determined primarily based on quoted prices of similar assets. The Group values its money market funds and certain equity securities using quoted prices for the underlying securities in active markets, and accordingly, the Group classifies the valuation techniques that use these inputs as Level 1. 11. | Fair Value Measurement (Continued) |
