| (2) | Financial risk management objectives and policies
The Company’s risk management objectives are to manage the market risk, credit risk and liquidity risk related to its operating activities. The Company identifies, measures and manages the aforementioned risks based on policy and risk preference. The Company has established appropriate policies, procedures and internal controls for financial risk management. Before entering into significant financial activities, approval process by the Board of Directors and Audit Committee must be carried out based on related protocols and internal control procedures. The Company complies with its financial risk management policies at all times.
| (3) | Market risk
Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risks comprise currency risk, interest rate risk and other price risk (such as equity price risk). Foreign currency risk The Company’s exposure to the risk of changes in foreign exchange rates relates primarily to the Company’s operating activities (when revenue or expense is denominated in a different currency from the Company’s functional currency) and the Company’s net investments in foreign subsidiaries. The Company applies natural hedges on the foreign currency risk arising from purchases or sales, and utilizes spot or forward exchange contracts to manage foreign currency risk and the net effect of the risks related to monetary financial assets and liabilities is minor. The notional amounts of the foreign currency contracts are the same as the amount of the hedged items. In principle, the Company does not carry out any forward exchange contracts for uncertain commitments. Furthermore, as net investments in foreign subsidiaries are for strategic purposes, they are not hedged by the Company. The foreign currency sensitivity analysis of the possible change in foreign exchange rates on the Company’s profit is performed on significant monetary items denominated in foreign currencies as of the end of the reporting period. When NTD strengthens/weakens against USD by 10%, the profit for the years ended December 31, 2022, 2023 and 2024 decreases/increases by NT$1,305 million, NT$620 million and NT$1,095 million, respectively. When RMB strengthens/weakens against USD by 10%, the profit for the years ended December 31, 2022, 2023 and 2024 decreases/increases by NT$572 million, NT$582 million and NT$615 million, respectively. When JPY strengthens/weakens against USD by 10%, the profit for the years ended December 31, 2022, 2023 and 2024 decreases/increases by NT$538 million, NT$290 million and NT$237 million, respectively. Interest rate risk The Company is exposed to interest rate risk arising from borrowing at floating interest rates. All of the Company’s bonds have fixed interest rates and are measured at amortized cost. As such, changes in interest rates would not affect the future cash flows. On the other hand, as the interest rates of the Company’s short-term and long-term bank loans are floating, changes in interest rates would affect the future cash flows but not the fair value. Please refer to Note 6(11), (13) and (14) for the range of interest rates of the Company’s bonds and bank loans. At the reporting dates, a change of 10 basis points of interest rate in a reporting period could cause the profit for the years ended December 31, 2022, 2023 and 2024 to decrease/increase by NT$19 million, NT$36 million and NT$45 million, respectively. Equity price risk The Company’s listed and unlisted equity securities, investments in convertible bonds and exchange right of the exchangeable bonds issued are susceptible to market price risk arising from uncertainties about future performance of equity markets. The Company’s equity investments are classified as financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income, the investments in convertible bonds which contain the right of conversion to equity instruments are classified as financial assets at fair value through profit or loss, and the exchange right of the exchangeable bonds issued is classified as financial liabilities at fair value through profit or loss as it does not satisfy the definition of an equity component. Please refer to Note 6(2), (3) and (12) for the relevant information. The sensitivity analysis for the equity instruments is based on the change in fair value as of the reporting date. A change of 5% in the price of the aforementioned financial assets at fair value through profit or loss of listed companies could increase/decrease the Company’s profit for the years ended December 31, 2022, 2023 and 2024 by NT$285 million, NT$270 million and NT$261 million, respectively. A change of 5% in the price of the aforementioned financial assets at fair value through other comprehensive income of listed companies could increase/decrease the Company’s other comprehensive income (loss) for the years ended December 31, 2022, 2023 and 2024 by NT$579 million, NT$722 million and NT$689 million, respectively. Please refer to Note 11(7) for sensitivity analysis information of other equity instruments or derivatives that are linked to such equity instruments whose fair value measurement is categorized under Level 3.
| (4) | Credit risk management
The Company only trades with approved and creditworthy third parties. Where the Company trades with third parties which have less credit, it will request collateral from them. It is the Company’s policy that all customers who wish to trade on credit terms are subject to credit verification procedures. In addition, notes and accounts receivable balances are monitored on an ongoing basis to decrease the Company’s exposure to credit risk. The Company mitigates the credit risks from financial institutions by limiting its counter parties to only reputable domestic or international financial institutions with good credit standing and spreading its holdings among various financial institutions. The Company’s exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these instruments. As of December 31, 2023 and 2024, accounts receivable from the top ten customers represent 67% and 66% of the total accounts receivable of the Company, respectively. The credit concentration risk of other accounts receivable is insignificant.
| (5) | Liquidity risk management
The Company’s objectives are to maintain a balance between continuity of funding and flexibility through the use of cash and cash equivalents, bank loans, bonds and lease. The table below summarizes the maturity profile of the Company’s financial liabilities based on the contractual undiscounted payments and contractual maturity:

| (7) | Fair value measurement
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either in the principal market for the asset or liability, or in the absence of a principal market, in the most advantageous market for the asset or liability. The principal or the most advantageous market must be accessible by the Company. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use. The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: Level 1 — Quoted (unadjusted) market prices in active markets for identical assets or liabilities, Level 2 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable, Level 3 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable. For assets and liabilities that are recognized in the financial statements on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

Fair values of financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income that are categorized into Level 1 are based on the quoted market prices in active markets. If there is no active market, the Company estimates the fair value by using the valuation techniques (income approach and market approach) in consideration of cash flow forecast, recent fund raising activities, valuation of similar companies, individual company’s development, market conditions and other economic indicators. If there are restrictions on the sale or transfer of a financial asset, which are a characteristic of the asset, the fair value of the asset will be determined based on similar but unrestricted financial assets’ quoted market price with appropriate discounts for the restrictions. To measure fair values, if the lowest level input that is significant to the fair value measurement is directly or indirectly observable, then the financial assets are classified as Level 2 of the fair value hierarchy, otherwise as Level 3. During the year ended December 31, 2023, as the private placement ordinary shares held by the Company’s subsidiary became publicly listed on the over-the-counter market in Taiwan in May 2023, the Company transferred NT$655 million of the financial assets at fair value through profit or loss measured at the end of the reporting period in the quarter from Level 2 to Level 1 fair value measurement. During the year ended December 31, 2024, there was no transfers between Level 1 and Level 2 fair value measurements. Reconciliation for fair value measurement in Level 3 fair value hierarchy were as follows:

| b. | Assets and liabilities not recorded at fair value but for which fair value is disclosed:
The fair value of bonds payable is estimated by the market price or using a valuation model. The model uses market-based observable inputs including share price, exchange price, volatility, risk-free interest rates and risk discount rates. The fair value of long-term loans is determined using discounted cash flow model, based on the Company’s current incremental borrowing rates of similar loans. The fair values of the Company’s cash and cash equivalents, receivables, refundable deposits, other financial assets, short-term loans, payables and guarantee deposits approximate their carrying amount.
