INDEPENDENT AUDITORS’ REPORT TRANSLATED FROM CHINESE

To the Board of Directors and Shareholders of Opto Tech Corporation

Opinion

We have audited the accompanying parent company only balance sheets of Opto Tech Corporation (the “ Company”) as at December 31, 2020 and 2019, and the related parent company only statements of comprehensive income, of changes in equity and of cash flows for the years then ended, and notes to the parent company only financial statements, including a summary of significant accounting policies.

In our opinion, the accompanying parent company only financial statements present fairly, in all material respects, the accompanying parent company only financial position of the Company as at December 31, 2020 and 2019, and its parent company only financial performance and its parent company only cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.

Basis for opinion

We conducted our audits in accordance with the Regulations Governing Auditing and Attestation of Financial Statements by Certified Public Accountants and generally accepted auditing standards in the Republic of China. Our responsibilities under those standards are further described in the Auditor’s’ responsibilities for the audit of the parent company only financial statements section of our report. We are independent of the Company in accordance with the Norm of Professional Ethics for Certified Public Accountants of the Republic of China, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the parent company only financial statements of the current period. These matters were addressed in the context of our audit of the parent company only financial statements as a whole, and in forming our opinion thereon, we do not provide a separate opinion on these matters.

Key audit matters for the parent company only financial statements of the current period are stated as

~2~

follows :

Key audit matter- Allowance for inventory valuation losses

Description

Please refer to Note 4(11) for accounting policies on inventory valuation, Note 5(2) for accounting estimates and assumption uncertainty on inventory valuation, and Note 6(5) for details of allowance for inventory valuation losses. As of December 31, 2020, the balances of inventories and allowance for inventory valuation losses were NT$ 1,206,710 thousand and NT$ 79,860 thousand, respectively.

As the value of the Company’s inventories are affected by market prices and product life cycles, there is a higher risk of obsolescence. For inventories aged over a certain period of time and individually identified as obsolete, the net realisable value is estimated based on historical data of inventory closeout. The net realisable value utilised in evaluating obsolete inventories involves uncertainty of estimation as it is subject to management’s judgement. Since inventories and allowance for inventory valuation losses were material to the parent company only financial statements, it was identified as a key audit matter.

How our audit addressed the matter

We performed the following audit procedures in respect of the above key audit matter:

Assessed the reasonableness of policies and procedures in the provision of allowance for inventory valuation losses and the reasonableness in the identification of obsolete inventories; validated the appropriateness of system logic of inventory aging report in order to confirm the compliance with respective policies; and assessed the reasonableness of the Company’s determination of the provision of allowance for inventory valuation losses through obtaining assessment documents and supporting evidences in relation to individually identified obsolete or damaged inventories from management.

Key audit matter- Estimation of fair values of unlisted securities without active market

Description

Please refer to Note 4(6)(7) for accounting policies on financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income or loss, Note 5(2) for accounting estimates and assumption uncertainty on estimation of financial assets-fair value measurement of unlisted stocks without active market, and Note 6(2) (3), 12(3) for details of financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income or loss. As of December 31, 2020, the carrying amount of unlisted securities without active market was NT$805,199

~3~

thousand.

For unlisted securities without active market held by the Company, management assesses their fair values through market approach or asset-based approach and takes into account the discount for liquidity. Since the valuation method is subject to management’s judgement and involves uncertainty, which would affect fair value, it was identified as a key audit matter.

How our audit addressed the matter

We performed the following audit procedures in respect of the above key audit matter:

Assessed the reasonableness of valuation method and parameters referred to in the appraisal report by the independent appraiser who was engaged by the management, including the net asset values measured at fair value, comparability and market liquidity of comparable companies; assessed the reasonableness of price multipliers and discounts for liquidity in the market.

– Key audit matters Cut-off of sales of goods from hub warehouse

Description

Please refer to Note 4(30) for accounting policies on revenue recognition.

For the types of revenue of Opto Tech Corporation, revenue from sales of goods from hub warehouse is recognised when the custodians (hub warehouses) deliver the goods to the customer (the control of goods have been transferred). Opto Tech Corporation recognises revenue based on movements of inventories contained in the statements or other information provided by the custodians. Because the frequency and timing of statements provided by custodians vary and the process of revenue recognition contains numerous manual procedures and judgement, which would potentially result in inaccurate timing of revenue recognition. Due to that the revenue from sales of goods from hub warehouse is material to Opto Tech Corporation, and the transaction amounts prior to and after the balance sheet date has significant effects on the financial statements, it was identified as a key audit matter.

How our audit addressed the matter

We performed the following audit procedures in respect of the above key audit matter:

Assessed and validated the appropriateness of management’s internal controls over the cut-off of sales of goods from hub warehouse prior to and after every month end in 2020, including verifying acceptance reports provided by the hub warehouse custodians and ensuring movements in inventories and cost of goods sold have been recorded in the correct periods. Furthermore, we performed

~4~

confirmation procedures or conducted inventory physical observation on inventory quantities held by hub warehouses and validated the quantities against accounting records.

Responsibilities of management and those charged with governance for the parent company only financial statements

Management is responsible for the preparation and fair presentation of the parent company only financial statements in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers” and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations as endorsed by the Financial Supervisory Commission, and for such internal control as management determines is necessary to enable the preparation of parent company only financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the parent company only financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Those charged with governance, including the audit committee, are responsible for overseeing the Company’s financial reporting process.

Auditor’s responsibilities for the audit of the parent company only financial statements

Our objectives are to obtain reasonable assurance about whether the parent company only financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the generally accepted auditing standards in the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these parent company only financial statements.

As part of an audit in accordance with the generally accepted auditing standards in the Republic of China, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

~5~

1. Identify and assess the risks of material misstatement of the parent company only financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

2. Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control.

3. Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

4. Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the parent company only financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern.

5. Evaluate the overall presentation, structure and content of the parent company only financial statements, including the disclosures, and whether the parent company only financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

6. Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company to express an opinion on the parent company only financial statements. We are responsible for the direction, supervision and performance of Opto Tech Corporation audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant

~6~

ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the parent company only financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

4. Summary of Significant Accounting Policies

The principal accounting policies applied in the preparation of the parent company only financial statements are set out below. These policies have been consistently applied to all the periods presented, unless otherwise stated.

~16~

(1) Compliance statement

The accompanying parent company only financial statements have been prepared in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers”.

(2) Basic of preparation

• A. Except for the following items, the accompanying parent company only financial statements have been prepared under the historical cost convention:

• (a) Financial assets and financial liabilities (including derivative instruments) at fair value through profit or loss.

• (b) Financial assets at fair value through other comprehensive income.

• (c) Defined benefit liabilities recognised based on present value of defined benefit obligation less the net amount of pension fund assets.

• B. The preparation of financial statements in conformity with IFRSs requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Company’s accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the financial statements are disclosed in Note 5.

(3) Foreign currency translation

Items included in the financial statements of each of the Company’s entities are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”).The parent company only financial statements are presented in New Taiwan dollars, which is the Company’s functional currency.

• A. Foreign currency transactions and balances

• (a) Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuation where items are remeasured. Foreign exchange gains and losses resulting from the settlement of such transactions are recognised in profit or loss in the period in which they arise.

• (b) Monetary assets and liabilities denominated in foreign currencies at the period end are retranslated at the exchange rates prevailing at the balance sheet date. Exchange differences arising upon re-translation at the balance sheet date are recognised in profit or loss.

• (c) Non-monetary assets and liabilities denominated in foreign currencies held at fair value through profit or loss are re-translated at the exchange rates prevailing at the balance sheet date; their translation differences are recognised in profit or loss. Non-monetary assets and liabilities denominated in foreign currencies held at fair value through other comprehensive income are re-translated at the exchange rates prevailing at the balance sheet date; their translation differences are recognised in other comprehensive income. However, nonmonetary assets and liabilities denominated in foreign currencies that are not measured at fair value are translated using the historical exchange rates at the dates of the initial transactions.

~17~

• B. Translation of foreign operations

  • (a) The operating results and financial position of all the group entities, associates and joint arrangements that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

    • i. Assets and liabilities for each balance sheet presented are translated at the closing exchange rate at the date of that balance sheet;

    • ii. Income and expenses for each statement of comprehensive income are translated at average exchange rates of that period; and

    • iii. All resulting exchange differences are recognised in other comprehensive income.

  • (b) When the foreign operation partially disposed of or sold is an associate, exchange differences that were recorded in other comprehensive income are proportionately reclassified to profit or loss as part of the gain or loss on sale. In addition, even when the Company retains partial interest in the former foreign associate or joint arrangement after losing significant influence over the former foreign associate, or losing joint control of the former joint arrangement, such transactions should be accounted for as disposal of all interest in these foreign operations.

  • (c) When the foreign operation partially disposed of or sold is a subsidiary, cumulative exchange differences that were recorded in other comprehensive income are proportionately transferred to the non-controlling interest in this foreign operation. In addition, even when the Company retains partial interest in the former foreign subsidiary after losing control of the former foreign subsidiary, such transactions should be accounted for as disposal of all interest in the foreign operation.

• (4) Classification of current and non-current items

• A. Assets that meet one of the following criteria are classified as current assets; otherwise they are classified as non-current assets:

  • (a) Assets arising from operating activities that are expected to be realised, or are intended to be sold or consumed within the normal operating cycle;

  • (b) Assets held mainly for trading purposes;

  • (c) Assets that are expected to be realised within twelve months from the balance sheet date;

  • (d) Cash and cash equivalents, excluding restricted cash and cash equivalents and those that are to be exchanged or used to settle liabilities more than twelve months after the balance sheet date.

• B. Liabilities that meet one of the following criteria are classified as current liabilities; otherwise they are classified as non-current liabilities:

  • (a) Liabilities that are expected to be settled within the normal operating cycle;

  • (b) Liabilities arising mainly from trading activities;

  • (c) Liabilities that are to be settled within twelve months from the balance sheet date;

~18~

• (d) Liabilities for which the repayment date cannot be extended unconditionally to more than twelve months after the balance sheet date. Terms of a liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification.

(5) Cash equivalents

Cash equivalents refer to short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. Time deposits that meet the definition above and are held for the purpose of meeting short-term cash commitments in operations are classified as cash equivalents.

(6) Financial assets at fair value through profit or loss

• A. Financial assets at fair value through profit or loss are financial assets that are not measured at amortised cost or fair value through other comprehensive income.

• B. On a regular way purchase or sale basis, financial assets at fair value through profit or loss are recognised and derecognised using trade date accounting.

• C. At initial recognition, the Company measures the financial assets at fair value and recognises the transaction costs in profit or loss. The Company subsequently measures the financial assets at fair value, and recognises the gain or loss in profit or loss.

• D. The Company recognises the dividend income when the right to receive payment is established, future economic benefits associated with the dividend will flow to the Company and the amount of the dividend can be measured reliably.

(7) Financial assets at fair value through other comprehensive income

• A. Financial assets at fair value through other comprehensive income comprise equity securities which are not held for trading, and for which the Company has made an irrevocable election at initial recognition to recognise changes in fair value in other comprehensive income and debt instruments which meet all of the following criteria:

• (a) The objective of the Company’s business model is achieved both by collecting contractual cash flows and selling financial assets; and

• (b) The assets’ contractual cash flows represent solely payments of principal and interest.

• B. On a regular way purchase or sale basis, financial assets at fair value through other comprehensive income are recognised and derecognised using trade date accounting.

• C. At initial recognition, the Company measures the financial assets at fair value plus transaction costs. The Company subsequently measures the financial assets at fair value: The changes in fair value of equity investments that were recognised in other comprehensive income are reclassified to retained earnings and are not reclassified to profit or loss following the derecognition of the investment. Dividends are recognised as revenue when the right to receive payment is established, future economic benefits associated with the dividend will flow to the Company and the amount of the dividend can be measured reliably.

~19~

(8) Accounts and notes receivable

• A. Accounts and notes receivable entitle the Company a legal right to receive consideration in exchange for transferred goods or rendered services.

• B. The short-term accounts and notes receivable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial.

(9) Impairment of financial assets

For accounts receivable or contract assets that do not contain a significant financing component, at each reporting date, the Company recognises the impairment provision for lifetime expected credit losses (ECLs).

(10) Derecognition of financial assets

The Company derecognises a financial asset when one of the following conditions is met:

• A. The contractual rights to receive the cash flows from the financial asset expire.

• B. The contractual rights to receive cash flows of the financial asset have been transferred and the Company has transferred substantially all risks and rewards of ownership of the financial asset.

• C. The contractual rights to receive cash flows of the financial asset have been transferred; however, the Company has not retained control of the financial asset.

(11) Inventories

Inventories are stated at the lower of cost and net realisable value. Cost is determined using the weighted-average method. The cost of finished goods and work in progress comprises raw materials, direct labour, other direct costs and related production overheads (allocated based on normal operating capacity). It excludes borrowing costs. The item-by-item approach is used in applying the lower of cost and net realisable value. Net realisable value is the estimated selling price in the ordinary course of business, less the estimated cost of completion and applicable variable selling expenses.

(12) Investments accounted for using equity method / associates

• A. Subsidiaries are all entities controlled by the Company. The Company controls an entity when the Company is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity.

• B. Inter-company transactions, balances and unrealised gains or losses on transactions between companies and the Company are eliminated. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Company.

• C. The Company’s share of its subsidiaries’ post-acquisition profits or losses is recognised in profit or loss, and its share of post-acquisition movements in other comprehensive income is recognised in other comprehensive income. When the Company’s share of losses in a subsidiary equals or exceeds its interest in the subsidiary, the Company recognise loss continuously in proportion to its ownership.

~20~

• D. Associates are all entities over which the Company has significant influence but not control. In general, it is presumed that the investor has significant influence, if an investor holds, directly or indirectly 20 percent or more of the voting power of the investee. Investments in associates are accounted for using the equity method and are initially recognised at cost.

• E. The Company’s share of its associates’ post-acquisition profits or losses is recognised in profit or loss, and its share of post-acquisition movements in other comprehensive income is recognized in other comprehensive income. When the Company’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Company does not recognise further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.

• F. When changes in an associate’s equity do not arise from profit or loss or other comprehensive income and such changes do not affect the Company’s ownership percentage of the associate, the Company recognises change in ownership interests of the associate in ‘capital surplus’ in proportion to its ownership.

• G. Unrealised gains on transactions between the Company and its associates are eliminated to the extent of the Company’s interest in the associates. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been adjusted where necessary to ensure consistency with the policies adopted by the Company.

• H. In the case that an associate issues new shares and the Company does not subscribe or acquire new shares proportionately, which results in a change in the Company’s ownership percentage of the associate but maintains significant influence on the associate, then ‘capital surplus’ and ‘investments accounted for under the equity method’ shall be adjusted for the increase or decrease of its share of equity interest. If the above condition causes a decrease in the Company’s ownership percentage of the associate, in addition to the above adjustment, the amounts previously recognised in other comprehensive income in relation to the associate are reclassified to profit or loss proportionately on the same basis as would be required if the relevant assets or liabilities were disposed of.

• I. Upon loss of significant influence over an associate, the Company remeasures any investment retained in the former associate at its fair value. Any difference between fair value and carrying amount is recognised in profit or loss.

• J. When the Company disposes its investment in an associate, if it loses significant influence over this associate, the amounts previously recognised in other comprehensive income in relation to the associate, are reclassified to profit or loss, on the same basis as would be required if the relevant assets or liabilities were disposed of. If it retains significant influence over this associate, the amounts previously recognised in other comprehensive income in relation to the associate are reclassified to profit or loss proportionately in accordance with the aforementioned approach.

~21~

• K. When the Company disposes its investment in an associate and loses significant influence over this associate, the amounts previously recognised as capital surplus in relation to the associate are transferred to profit or loss. If it retains significant influence over this associate, the amounts previously recognised as capital surplus in relation to the associate are transferred to profit or loss proportionately.

• L. Pursuant to the “Regulations Governing the Preparation of Financial Reports by Securities Issuers,” profit (loss) of the current period and other comprehensive income in the nonconsolidated financial statements shall equal to the amount attributable to owners of the parent in the financial statements prepared with basis for consolidation. Owners’ equity in the nonconsolidated financial statements shall equal to equity attributable to owners of the parent in the financial statements prepared with basis for consolidation.

• (13) Property, plant and equipment

• A. Property, plant and equipment are initially recorded at cost. Borrowing costs incurred during the construction period are capitalised.

• B. Subsequent costs are included in the asset’s carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognised. All other repairs and maintenance are charged to profit or loss during the financial period in which they are incurred.

• C. Land is not depreciated. Other property, plant and equipment apply cost model and are depreciated using the straight-line method to allocate their cost over their estimated useful lives. Each part of an item of property, plant, and equipment with a cost that is significant in relation to the total cost of the item must be depreciated separately.

• D. The assets’ residual values, useful lives and depreciation methods are reviewed, and adjusted if appropriate, at each financial year-end. If expectations for the assets’ residual values and useful lives differ from previous estimates or the patterns of consumption of the assets’ future economic benefits embodied in the assets have changed significantly, any change is accounted for as a change in estimate under IAS 8, ‘Accounting Policies, Changes in Accounting Estimates and Errors’, from the date of the change. The estimated useful lives of property, plant and equipment are as follows:

re as follows:
Buildings and structures	10 ~ 50 years
Machinery and equipment	08 ~ 10 years
Utility equipment	06 ~ 25 years
Pollution prevention facilities	08 ~ 20 years
Transportation equipment	03 ~05 years
Office equipment	03 ~07 years
Other equipment	03 ~ 25 years

~22~

(14) Leasing arrangements (lessee) － right-of-use assets/ lease liabilities

• A. Leases are recognised as a right-of-use asset and a corresponding lease liability at the date at which the leased asset is available for use by the Company. For short-term leases or leases of low-value assets, lease payments are recognised as an expense on a straight-line basis over the lease term.

• B. Lease liabilities include the net present value of the remaining lease payments at the commencement date, discounted using the incremental borrowing interest rate. Lease payments are fixed payments, less any lease incentives receivable. The Company subsequently measures the lease liability at amortised cost using the interest method and recognises interest expense over the lease term. The lease liability is remeasured and the amount of remeasurement is recognised as an adjustment to the right-of-use asset when there are changes in the lease term or lease payments and such changes do not arise from contract modifications.

• C. At the commencement date, the right-of-use asset is stated at cost comprising the following: (a) The amount of the initial measurement of lease liability;

• (b) Any lease payments made at or before the commencement date;

• (c) Any initial direct costs incurred by the lessee; and

• (d) An estimate of costs to be incurred by the lessee in dismantling and removing the underlying asset, restoring the site on which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease.

The right-of-use asset is measured subsequently using the cost model and is depreciated from the commencement date to the earlier of the end of the asset’s useful life or the end of the lease term. When the lease liability is remeasured, the amount of remeasurement is recognised as an adjustment to the right-of-use asset.

(15) Investment property

Investment property is stated initially at its cost which includes purchase price and any direct expenses. Directly attributable expenses include legal service expense, tax on the transfer of properties and other transaction costs and subsequently measured using the cost model.

(16) Intangible assets

Intangible assets, mainly computer software, is stated at cost and amortised on a straight-line basis over its estimated useful life of 2 to 10 years.

(17) Impairment of non-financial assets

The Company assesses at each balance sheet date the recoverable amounts of those assets where there is an indication that they are impaired. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell or value in use. When the circumstances or reasons for recognizing impairment loss for an asset in prior years no longer exist or diminish, the impairment loss is reversed. The increased carrying amount due to reversal should not be more than what the depreciated or amortised historical cost would have been if the impairment had not been

~23~

recognised.

(18) Borrowings

• A. Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognised in profit or loss over the period of the borrowings using the effective interest method.

• B. Fees paid on the establishment of loan facilities are recognised as transaction costs of the loan to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down occurs. To the extent there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalised as a pre-payment for liquidity services and amortised over the period of the facility to which it relates.

• (19) Notes and accounts payable

• Notes and accounts payable are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. They are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method. However, short-term accounts payable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial.

(20) Financial liabilities at fair value through profit or loss

• A. Financial liabilities are classified in this category of held for trading if acquired principally for the purpose of repurchasing in the short-term. Derivatives are also categorised as financial liabilities held for trading unless they are designated as hedges, or financial liabilities at fair value through profit or loss. Financial liabilities that meet one of the following criteria are designated as at fair value through profit or loss at initial recognition:

• (a) Hybrid (combined) contracts; or

• (b) They eliminate or significantly reduce a measurement or recognition inconsistency; or

• (c) They are managed and their performance is evaluated on a fair value basis, in accordance with a documented risk management policy.

• B. At initial recognition, the Company measures the financial liabilities at fair value. All related transaction costs are recognised in profit or loss. The Company subsequently measures these financial liabilities at fair value with any gain or loss recognised in profit or loss.

• C. If the credit risk results in fair value changes in financial liabilities designated as at fair value through profit or loss, they are recognised in other comprehensive income in the circumstances other than avoiding accounting mismatch or recognising in profit or loss for loan commitments or financial guarantee contracts.

~24~

(21) Derecognition of financial liabilities

A financial liability is derecognised when the obligation under the liability specified in the contract is discharged or cancelled or expires.

(22) Offsetting financial instruments

Financial assets and liabilities are offset and reported in the net amount in the balance sheet when there is a legally enforceable right to offset the recognised amounts and there is an intention to settle on a net basis or realise the asset and settle the liability simultaneously.

(23) Non-hedging derivatives

Non-hedging derivatives are initially recognised at fair value on the date a derivative contract is entered into and recorded as financial assets or financial liabilities at fair value through profit or loss. They are subsequently remeasured at fair value and the gains or losses are recognised in profit or loss.

(24) Provisions

Provisions, mainly warranties, are recognised when the Company has a present legal or constructive obligation as a result of past events, and it is probable that an outflow of economic resources will be required to settle the obligation and the amount of the obligation can be reliably estimated. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation on the balance sheet date, which is discounted using a pre-tax discount rate that reflects the current market assessments of the time value of money and the risks specific to the obligation. When discounting is used, the increase in the provision due to passage of time is recognised as interest expense. Provisions are not recognised for future operating losses.

(25) Employee benefits

• A. Short-term employee benefits

Short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in respect of service rendered by employees in a period and should be recognised as expense in that period when the employees render service.

• B. Pensions

• (a) Defined contribution plans

For defined contribution plans, the contributions are recognised as pension expense when they are due on an accrual basis. Prepaid contributions are recognised as an asset to the extent of a cash refund or a reduction in the future payments.

(b) Defined benefit plans

• i. Net obligation under a defined benefit plan is defined as the present value of an amount of pension benefits that employees will receive on retirement for their services with the Company in current period or prior periods. The liability recognised in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The net defined benefit obligation is calculated annually by independent actuaries using the projected unit credit

~25~

method. The rate used to discount is determined by using interest rates of government bonds (at the balance sheet date) that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension liability.

     - ii. Remeasurements arising on defined benefit plans are recognised in other comprehensive income in the period in which they arise and are recorded as retained earnings.

• C. Termination benefits

  • Termination benefits are employee benefits provided in exchange for the termination of employment as a result from either the Company’s decision to terminate an employee’s employment before the normal retirement date, or an employee’s decision to accept an offer of redundancy benefits in exchange for the termination of employment. The Company recognises expense as it can no longer withdraw an offer of termination benefits or it recognises relating restructuring costs, whichever is earlier. Benefits that are expected to be due more than 12 months after balance sheet date shall be discounted to their present value.

• D. Employees’ compensation and directors’ and supervisors’ remuneration

  • Employees’ compensation and directors’ and supervisors’ remuneration are recognised as expense and liability, provided that such recognition is required under legal or constructive obligation and those amounts can be reliably estimated. Any difference between the resolved amounts and the subsequently actual distributed amounts is accounted for as changes in estimates.

• (26) Employee share based payment

• For the equity-settled share-based payment arrangements, the employee services received are measured at the fair value of the equity instruments granted at the grant date, and are recognised as compensation cost over the vesting period, with a corresponding adjustment to equity. The fair value of the equity instruments granted shall reflect the impact of market vesting conditions and nonmarket vesting conditions. Compensation cost is subject to adjustment based on the service conditions that are expected to be satisfied and the estimates of the number of equity instruments that are expected to vest under the non-market vesting conditions at each balance sheet date.

• Ultimately, the amount of compensation cost recognised is based on the number of equity instruments that eventually vest.

• (27) Income tax

• A. The tax expense for the period comprises current and deferred tax. Tax is recognised in profit or loss, except to the extent that it relates to items recognised in other comprehensive income or items recognised directly in equity, in which cases the tax is recognised in other comprehensive income or equity.

• B. The current income tax expense is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the countries where the Company and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in accordance with applicable tax regulations. It establishes provisions

~26~

where appropriate based on the amounts expected to be paid to the tax authorities. An additional 10% tax is levied on the unappropriated retained earnings and is recorded as income tax expense in the year the stockholders resolve to retain the earnings.

• C. Deferred tax is recognised, using the balance sheet liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the balance sheet. Deferred tax is provided on temporary differences arising on investments in subsidiaries, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is determined using tax rates (and laws) that have been enacted or substantially enacted by the balance sheet date and are expected to apply when the related deferred tax asset is realised or the deferred tax liability is settled.

• D. Deferred tax assets are recognised only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilised. At each balance sheet date, unrecognised and recognised deferred tax assets are reassessed.

• E. Current income tax assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognised amounts and there is an intention to settle on a net basis or realise the asset and settle the liability simultaneously. Deferred tax assets and liabilities are offset on the balance sheet when the entity has the legally enforceable right to offset current tax assets against current tax liabilities and they are levied by the same taxation authority on either the same entity or different entities that intend to settle on a net basis or realise the asset and settle the liability simultaneously.

• F. A deferred tax asset shall be recognised for the carryforward of unused tax credits resulting from acquisitions of equipment or technology and research and development expenditures to the extent that it is possible future taxable profit will be available against which the unused tax credit can be utilised.

(28) Share capital

• A. Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or stock options are shown in equity as a deduction, net of tax, from the proceeds.

(29) Dividends

Dividends are recorded in the Company’s financial statements in the period in which they are resolved by the Company’s shareholders. Cash dividends are recorded as liabilities.

• (30) Revenue recognition

• A. Sales of goods

  • (a) The Company is primarily engaged in the manufacture and sales of semiconductor components. Sales are recognised when control of the products has transferred, being when the products are delivered to the client, the client has full discretion over the channel and price to sell the products, and there is no unfulfilled obligation. Delivery occurs when the products have been shipped to the specific location, the risks of obsolescence and loss have been transferred to the client, and either the client has accepted the products in accordance with the sales contract, or the Company has objective evidence that all criteria for acceptance have been satisfied. As the time interval between the transfer of committed goods and the payment of customer does not exceed one year, the Company does not adjust the transaction price to reflect the time value of money.

  • (b) A receivable is recognised when the goods are delivered as this is the point in time that the consideration is unconditional because only the passage of time is required before the payment is due.

• B. Sales and installation of systems products

  • (a) Contracts include sales and installation services of systems products. The system products and the installation services provided by the Company are mostly not distinct and are identified to be one performance obligation since the installation services involve significant customisation and modification. Some contracts are accounted for as a separate performance obligation, and the transaction price will be allocated to each performance obligation based on the stand-alone selling prices. The Company recognises revenue when the performance obligation is satisfied.

  • (b) The Company provides standard warranties on system products sold. Warranties are estimated based on historical warranty data of system products, and recognised when the amount can be reliably estimated.

• (31) Reorganisation

• Reorganisation under common control is recognised using book value approach.

• Critical Accounting Judgements, Estimates and Key Sources of Assumption Uncertainty

• The preparation of these financial statements requires management to make critical judgements in applying the Company’s accounting policies and make critical assumptions and estimates concerning future events. Assumptions and estimates may differ from the actual results and are continually evaluated and adjusted based on historical experience and other factors. Such assumptions and estimates have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year; and the related information is addressed below:

~28~

(1) Critical judgements in applying the Company’s accounting policies

None.

(2) Critical accounting estimates and assumptions

• A. Allowance for inventory valuation losses

As the value of the Company’s inventories are effected by market prices and product life cycles, there is a higher risk of obsolescence. For inventories aged over a certain period of time and individually identified as obsolete, the net realisable value is estimated based on historical data of inventory closeout. The net realisable value utilised in evaluating obsolete inventories involves uncertainty of estimation as it is subject to management’s judgement. Inventories and allowance for inventory voluation losses were material to the financial statements.

As of December 31, 2020, the carrying amount of inventories was $1,126,850.

• B. Financial assets - fair value measurement of unlisted stocks without active market For unlisted securities without active market held by the Company, management assesses their fair values through market approach and takes into account the discount for liquidity. The valuation method is subject to management’s judgement and involves uncertainty, which would effect fair value. Please refer to Note 12(3).

As of December 31, 2020, the carrying amount of unlisted stocks without active market was $805,199.

• (d) The Bank of Taiwan was commissioned to manage the Fund of the Company’s defined benefit pension plan in accordance with the Fund’s annual investment and utilisation plan and the “Regulations for Revenues, Expenditures, Safeguard and Utilisation of the Labor Retirement Fund” (Article 6: The scope of utilisation for the Fund includes deposit in domestic or foreign financial institutions, investment in domestic or foreign listed, over-the-counter, or private placement equity securities, investment in domestic or foreign real estate securitization products, etc.). With regard to the utilisation of the Fund, its minimum earnings in the annual distributions on the final financial statements shall be no less than the earnings attainable from the amounts accrued from two-year time deposits with the interest rates offered by local banks. If the earnings is less than aforementioned rates, government shall make payment for the deficit after being authorized by the Regulator. The Company and has no right to participate in managing and operating that fund and hence the Company is unable to disclose the classification of plan assets fair value in accordance with IAS 19 paragraph 142. The composition of fair value of plan assets as of December 31, 2020 and 2019 is given in the Annual Labor Retirement Fund Utilisation Report announced by the government.

• (e) The principal actuarial assumptions used were as follows:

					Year	ended December 31	ended December 31	ended December 31
					2020			2019
Discount rate						0.39%			0.82%
Future salary increases						3.00%			3.00%
Future mortality rate was estimated based on			the	5thTaiwan Standard			Ordinary Experience
Mortality Table.
Because the main actuarial assumption changed,					the present value of			defined	benefit
obligation is affected. The analysis was as follows:
		Discount		rate		Future salaryincreases
		Increase		Decrease		Increase		Decrease
		0.5%		0.5%		0.5%		0.5%
December 31, 2020
Effect on present value of

December 31, 2019
Effect on present value of
defined benefit obligation	($	47,832)	$		52,580	$	51,155	($	47,083)

The sensitivity analysis above is based on one assumption which changed while the other conditions remain unchanged. In practice, more than one assumption may change all at once. The method of analysing sensitivity and the method of calculating net pension liability in the balance sheet are the same.

~42~

The methods and types of assumptions used in preparing the sensitivity analysis did not change compared to the previous period.

• (f) Expected contributions to the defined benefit pension plans of the Company for the year ending December 31, 2021 amount to $8,059.

In order to maintain or adjust the capital structure, the Company may adjust the amount of dividends paid to shareholders or issue new shares to reduce debt. The Company monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings less cash and cash equivalents. Total capital is calculated as ‘equity’ as shown in the balance sheet plus net debt.

As of December 31, 2020 and 2019, the gearing ratios were (32.57%) and (34%), respectively.

Other components of equity would have increased/decreased by $86,979 and $100,613 as a result of gains/losses on equity securities classified as at fair value through other comprehensive income.

Interest rate risk

• i. The Company’s interest rate risk arises from long-term and short-term borrowings. Borrowings issued at floating rates expose the Company to cash flow interest rate risk which is partially offset by cash and cash equivalents held at floating rates. During the years ended December 31, 2020 and 2019, the Company’s borrowings at floating rate were denominated in TWD, USD and JPY.

• ii. At December 31, 2020 and 2019, if interest rates on borrowings had been 100 basis point higher/lower with all other variables held constant, post-tax profit for the years ended December 31, 2020 and 2019 would have been $7,612 and $7,765 lower/higher, respectively, mainly as a result of higher/lower interest expense on floating rate borrowings.

• (b) Credit risk

• i. Credit risk refers to the risk of financial loss to the Company arising from default by the clients or counterparties of financial instruments on the contract obligations. According to the Company’s credit policy, each local entity in the Company is responsible for managing and analysing the credit risk for each of their new clients before standard payment and delivery terms and conditions are offered. Internal risk control assesses the credit quality of the customers, taking into account their financial position, past experience and other factors, the utilisation of credit limits is regularly monitored. Credit risk arises from cash and equivalents, derivative financial instruments and deposits with bank and financial

~63~

institutions, as well as operating activities, including outstanding receivables.

• ii. The default occurs when the contract payments are past due over 181 days for distributors and 361 days for other customers, respectively.

• iii. The Company classifies customers’ accounts receivable, in accordance with credit risk on trade and customer types. The Company applies the simplified approach using loss rate methodology to estimate expected credit loss under the provision matrix basis.

• iv. The following indicators are used to determine whether the credit impairment of debt instruments has occurred:

• (i) It becomes probable that the issuer will enter bankruptcy or other financial reorganization due to their financial difficulties;

• (ii) The disappearance of an active market for that financial asset because of financial difficulties;

• (iii) Default or delinquency in interest or principal repayments;

• (iv) Adverse changes in national or regional economic conditions that are expected to cause a default.

• v. The Company used historical and timely information to assess the default possibility of notes receivable and accounts receivable (including related parties). As of December 31, 2020 and 2019, the loss rate methodology is as follows:

At December 31, 2020 Expected loss rate Total book value Loss allowance At December 31, 2019 Expected loss rate Total book value Loss allowance	Individual 100% 4,997 $ 4,997 $ Individual 100% - $ - $	Group 0.01%~100% 1,635,285 $ 3,023 $ Group 0.1%~100% 1,451,450 $ 20,700 $	Total
			1,640,282 $
			8,020 $
			Total
			1,451,450 $
			20,700 $

• vi. As at December 31, 2020 and 2019, without taking into account any collateral held or other credit enhancements, the maximum exposure to credit risk in respect of the amount that best represents the Company’s accounts receivable was $1,632,262 and $1,430,750, respectively.

~64~

• vii. Movements in relation to the company applying the simplified approach to provide loss allowance for accounts receivable are as follows:

			2020			2019
		Accounts receivable			Accounts receivable
At January 1	$		20,700	$		32,002
Provision (reversal) of impairment loss			2,408	(		2,478)
Write-offs	(		15,088)	(		8,824)
At December 31	$		8,020	$		20,700

• viii. The Company conducts business with banks and financial institutions with sound reputation, and therefore do not expect the financial assets at amortized cost to have credit risk.

(c) Liquidity risk

• i. Cash flow forecasting is performed in the operating entities of the Company and aggregated by Company treasury. Company treasury monitors rolling forecasts of the Company’s liquidity requirements to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn committed borrowing facilities at all times.

• ii. The table below analyses the Company’s non-derivative financial liabilities and derivative financial liabilities into relevant maturity groupings based on the remaining period at the balance sheet date to the contractual maturity date for non-derivative financial liabilities and to the expected maturity date for derivative financial liabilities.

(3) Fair value information

• A. The different levels that the inputs to valuation techniques are used to measure fair value of financial and non-financial instruments have been defined as follows:

• Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date. A market is regarded as active where a market in which transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis.

• Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly.

• Level 3: Unobservable inputs for the asset or liability.

• B. Fair value information of investment property at cost is provided in Note 6(9).

• C. The carrying amounts of cash and cash equivalents, notes receivable, accounts receivable, other receivables, short-term borrowings, notes payable, accounts payable, other payables, lease liabilities and long-term borrowings are approximate to their fair value.

~66~

• D. The related information of financial and non-financial instruments measured at fair value by level on the basis of the nature, characteristics and risks of the assets and liabilities as at December 31, 2020 and 2019 is as follows:

----- End of picture text -----

• E. The methods and assumptions the Company used to measure fair value are as follows:

• (a) The instruments the Company used market quoted prices as their fair values (that is, Level 1) are composed of listed shares using closing price and open-end fund using net asset value at balance sheet date.

• (b) Except for financial instruments with active markets, the fair value of other financial instruments is measured by using valuation techniques or by reference to counterparty quotes.

• (c) When assessing non-standard and low-complexity financial instruments, the Company adopts valuation technique that is widely used by market participants. The inputs used in the valuation method to measure these financial instruments are normally observable in the market. Forward exchange contracts are usually valued based on the current forward exchange rate.

~67~

• (d) The output of valuation model is an estimated value and the valuation technique may not be able to capture all relevant factors of the Company’s financial and non-financial instruments. Therefore, the estimated value derived using valuation model is adjusted accordingly with additional inputs. In accordance with the Company’s management policies and relevant control procedures relating to the valuation models used for fair value measurement, management believes adjustment to valuation is necessary in order to reasonably represent the fair value of financial and non-financial instruments at the balance sheet. The inputs and pricing information used during valuation are carefully assessed and adjusted based on current market conditions.

• F. For the years ended December 31, 2020 and 2019, there was no transfer between Level 1 and Level 2.

• G. The following chart is the movement of Level 3 financial instruments of equity securities for the years ended December 31, 2020 and 2019.

		2020			2019
At January 1	$		951,466	$		889,926
Acquired in the period	(		3,600)			3,600

Losses recognised in other
comprehensive income	(		142,804)			57,986
At December 31	$		805,199	$		951,466

• G. For the years ended December 31, 2020 and 2019, there was no transfer into or out from Level 3.

• H. Financial segment is in charge of valuation procedures for fair value measurements being categorized within Level 3, which is to verify independent fair value of financial instruments. Such assessment is to ensure the valuation results are reasonable by applying independent information to make results close to current market conditions and reviewing periodically.

~68~

• I. The following is the qualitative information of significant unobservable inputs and sensitivity analysis of changes in significant unobservable inputs to valuation model used in Level 3 fair value measurement:

Unlisted shares Unlisted shares Non-derivative equity: Unlisted shares Unlisted shares Non-derivative equity:	Fair value at December Valuation 31,2020 technique 698,209 $ Market comparable companies 106,990 Net asset value Fair value at December Valuation 31,2019 technique 841,013 $ Market comparable companies 106,853 Net asset value	Significant unobservable input Price to earnings ratio multiple Discount for lack of volatility Discount for lack of volatility Significant unobservable input Price to earnings ratio multiple Discount for lack of volatility Discount for lack of volatility	Range (weighted average) 0.94~2.3 30%~35% 19.25% Range (weighted average) 0.75~1.21 25%~35% 19.25%	Relationship of inputs to fair value The higher the multiple, the higher the fair value. The higher the discount for lack of marketability, the lower the fair value. The higher the discount for lack of marketability, the lower the fair value. Relationship of inputs to fair value
				The higher the multiple, the higher the fair value. The higher the discount for lack of marketability, the lower the fair value. The higher the discount for lack of marketability, the lower the fair value.

~69~

• J. The Company has carefully assessed the valuation models and assumptions used to measure fair value. However, use of different valuation models or assumptions may result in different measurements. The following is the effect of profit or loss or of other comprehensive income from financial assets and liabilities categorised within Level 3 if the inputs used to valuation models have changed:

December 31, 2020
