Summary of Significant Unobservable Inputs of Fair Value Measurement in Level 3 Fair Value Hierarchy

Significant unobservable inputs of fair value measurement in Level 3 fair value hierarchy were as follows:

As of December 31, 2022
Category		Valuation technique		Significant unobservable inputs		Quantitative information		Interrelationship between inputs and fair value		Sensitivity analysis of interrelationship between inputs and fair value
Unlisted stock		Market Approach		Discount for lack of marketability		0% - 50%		The greater degree of lack of marketability, the lower the estimated fair value is determined.		A change of 5% in the discount for lack of marketability of the aforementioned fair values of unlisted stocks could decrease/increase the Company’s profit (loss) for the year ended December 31, 2022 by NT$273 million and NT$198 million, respectively, and decrease/increase the Company’s other comprehensive income (loss) for the year ended December 31, 2022 by NT$248 million.
Embedded derivatives in exchangeable bonds		Binomial tree valuation model		Volatility		36.46%		The higher the volatility, the higher the estimated fair value is determined.		A change of 5% in the volatility could decrease/increase the Company’s profit (loss) for the year ended December 31, 2022 by NT$77 million and NT$67 million, respectively.
