Independent Auditors’ Report

To the Board of Directors of Optimax Technology Corporation:

Opinion

We have audited the accompanying consolidated balance sheets of Optimax Technology Corporation and its subsidiaries (the “Group”) as at December 31, 2020, and 2019, and the related consolidated statements of comprehensive income, of changes in equity and cash flows for the years, then ended, and notes to the consolidated financial statements, including a summary of significant accounting policies, and others explanatory information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of Optimax Technology Corporation and its subsidiaries as at December 31, 2020, and 2019, and its consolidated financial performance and its consolidated cash flows for the years then ended by following the “Regulations Governing the Preparation of Financial Reports by Securities issuers” and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretation as endorsed by the Financial Supervisory Commission.

Basis for Opinion

We conducted our audits by following the regulations governing auditing and attestation of financial statements by certified public accountants and generally accepted auditing standards in the Republic of China (ROC GAAS). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Group in accordance with the Code of Professional Ethics for Certified Public Accountants in the Republic of China (the “code”), and we have fulfilled our other ethical responsibilities in accordance with the Code. Based on our audits and the audits report of other independent accountants, 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 consolidated financial statements for the current period. These matters were addressed in the context of our audit of the consolidated 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 Group’s consolidated financial statements of the current period are stated as follows:

1. Expression and disclosure of non-current assets held for sale

For the accounting policy of the non-current assets held for sale, please refer to Note 4 (7) of the

consolidated financial report; for the accounting items of non-current assets held for sale, please refer to the Note 6 (7) of the consolidated financial report.

In order to activate assets and reduce operating expenses, Optimax Technology Corporation and its subsidiaries sold the branch in Southern Taiwan Science Park and related ancillary equipment to Taiwan Semiconductor Manufacturing Co., Ltd. on August 12, 2020 through a resolution of the board of directors and signed a real estate purchase contract on October 19, 2020 with a total price of NT$3,832,500,000 (tax included). The above asset disposal is assessed by the management to be completed within one year.

4

In accordance with International Financial Reporting Standards No. 5, the book value and the public value minus the cost of sale will be used to reduce the amount of assets, and the non-current assets for sale will be transferred. The amount of other assets is significant, and the classification and expression of the consolidated financial report involves management's assessment of the possibility of asset sales, so noncurrent assets held for sale is listed as one of the key audit matters.

The concern of audit procedure:

(1) Understand the procedures and internal control of the acquisition or disposal of assets by Optimax Technology Corporation and its subsidiaries, and evaluate the design and implementation of the internal control of major asset transactions effective.

(2) Review the proceedings of the board of directors' resolutions to dispose of assets, the written consent of the creditor bank, and the signed asset disposal contract, to confirm that the management has obtained the purchase commitment and meets the general conditions and business practices, and has been approved by the creditor bank for evaluation. Whether the timing of the transfer of non-current assets to be sold is appropriate or not.

(3) When the classification is confirmed as a non-current asset for sale, the management obtains the fair value evaluation information of the asset, evaluates the reasonableness of the fair market value, and recalculates the amount of impairment loss (recovery benefit).

(4) Assess whether the management's expression and disclosure of non-current assets held for sale meets the requirements to determine the adequacy of the financial report expression.

2. Asset impairment assessment

For the accounting policy of asset impairment, please refer to Note 4 (10) of the consolidated financial report; for the uncertainty of the accounting estimates and assumptions of the asset impairment assessment, please refer to Note 5 of the consolidated financial report.; for the accounting items of asset impairment, please refer to the Note 6 (8) and Note 6 (11) of the consolidated financial report.

Optimax Technology Corporation and its subsidiaries (the “Group”) is a highly capitalized industry and is facing interference from many factors such as the economic environment and industry competition; because the assessment of asset impairment requires the process of predicting and discounting future cash flows to estimate the recoverable amount, and this process is inherently highly uncertain, therefore the asset impairment assessment is listed as one of the key audit matters.

The concern of audit procedure:

(1) Understand the relevant policies and processing procedures of Optimax Technology Corporation and its subsidiaries for impairment assessment, and assess the cash-generating units recognized by the management for impairment and the signs of internal and external impairment.

(2) Consider whether all assets that require annual impairment testing have been fully included in the management evaluation procedure.

• (3) Assess the rationality of the evaluation method used by management to measure the recoverable amount.

(4) For the recoverable amount determined by the independent evaluation report issued by the third party appointed by Optimax Technology Corporation and its subsidiaries, review the reasonableness of the relevant assumptions, and evaluate the qualification and independence of the appraiser to confirm the Fair

value of investment real estate.

5

• (5) Assess the uncertainties and related assumptions involved in the process of asset impairment loss, and consider whether the relevant disclosures of Optimax Technology Corporation and its subsidiaries are sufficient.

Emphasis on matters-extension of the joint loan case

As stated in Notes 6 (12) and 6 (16) of the consolidated financial statement, in accordance with the ”Key Points for the Ministry of Economic Affairs to Assist Enterprises in Handling Bank Credit and Debt Negotiations'', Optimax Technology Corporation applied to the Industrial Bureau of the Ministry of Economic Affairs on April 10, 2020, to assist in the negotiation of bank claims and debts, requesting that short-term credit extension periods be extended to December 7, 2021, and medium and long-term loans extended for one year. The bank was held a delegation meeting on June 19, 2020, and on November 17, 2020, the majority of creditor banks agreed through written consent that the short-term credit extension periods was extended to December 7, 2021 and the mid- and long-term loan repayment period was extended for one year. All operating procedures were completed on December 30, 2020. Optimax Technology Corporation applied to the Industrial Bureau of the Ministry of Economic Affairs on April 25, 2019, in accordance with the” Key Points for the Ministry of Economic Affairs to Assist Enterprises in Handling Bank Credit and Debt Negotiations'', to assist in the negotiation of bank claims and debts, requesting that short-term credit extension periods be extended to December 7, 2020, and medium and long-term loans extended for one year. The bank was held a delegation meeting on June 26, 2019, and on November 25, 2019, the majority of creditor banks agreed through written consent that the short-term credit extension periods was extended to December 7, 2020 and the mid- and longterm loan repayment period was extended for one year. All operating procedures were completed on March 3, 2020. The accountant did not amend the review results.

Other Matters─Parent company only financial l reports

Optimax Technology Corporation has edited the individual financial report in year 2020 and 2019, and the accountant and issued by this audit report expressed an unqualified opinion and an opinion of emphasis on matters paragraph on file for reference.

Responsibilities of management and those charged with governance for the separate financial statements

Management is responsible for the preparation and fair presentation of the separate financial statements in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers”, and for such internal control as management determines is necessary to enable the preparation of separate financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the ability of Optimax Technology Corporation. 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 Optimax Technology Corporation or to cease operations, or has no realistic alternative but to do so. Those charged with governance, including Audit Committee, are responsible for overseeing the financial reporting process of Optimax Technology Corporation.

Independent auditor’s responsibilities for the audit of the separate financial statements

Our objectives are to obtain reasonable assurance about whether the separate financial statements as a whole area 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 ROC GAAS 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 separate financial statements.

As part of an audit in accordance with ROC GAAS, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

1. Identifying and assess the risks of material misstatement of the separate 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 no detecting a material misstatement 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 internal control of Optimax Technology Corporation.

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 ability of Optimax Technology Corporation. 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 separate 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 Optimax Technology Corporation. to cease to continue as a going concern.

5. Evaluate the overall presentation, structure and content of the separate financial statements, including the disclosures, and whether the separate 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 Optimax Technology Corporation. to express an opinion on the separate financial statements. We are responsible for the direction, supervision and performance of the audit. We remain solely responsible for our audit opinion.

7

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 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 separate financial statements of the year ended December 31,2019 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 auditor’s 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 these consolidated financial statements are set out below.

(1) Compliance statement

The consolidated financial statements of the Group have been prepared in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers”, International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations as endorsed by the FSC (collectively referred herein as the “IFRSs”).

(2) Basis of preparation

Except for the following items, the consolidated financial statements have been prepared under the historical cost convention:

• A. Financial instruments at fair value through profit or loss.

• B. Net defined benefit liability at defined benefit obligation deducted plan assets through fair value.

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 consolidated company’s accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 5.

14

(3) Basis of consolidation

• A. Basis for preparation of consolidated financial statements:

• This consolidated financial report includes the company and the entities (subsidiaries) controlled by the company.

The consolidated comprehensive income statement has been included the operating profit and loss from the acquired or executed subsidiary company in the current period since the acquisition date or to the date of disposition.

The financial report of the subsidiary has been adjusted so that its accounting policy is consistent with the consolidated company’s accounting policy.

When preparing the consolidated financial report, the transactions, account balances, income and expenses and losses have been completely eliminated.

Changes in a parent’s ownership interest in a subsidiary that do not result in the parent losing control of the subsidiary are accounted for as equity transactions. The book amount of the consolidated company and non-controlling interests has been adjusted to reflect changes in its relative equity in subsidiaries. Adjustment of non-controlling interests of the difference between the amount and the fair value of the consideration paid or received is directly recognized as a right and the benefits belong to the owners of the company.

When the consolidated company loses control of the subsidiary, the disposition profit and loss is one of the following two difference: (1) the fair value of the consideration received and the remaining investment in the former subsidiary are counted at the fair value at the date of loss of control, and (2) the assets of the former subsidiary (including goodwill), together with liabilities and non-controlling interests, they are counted based on the book amount on the day when control is lost. For all the amounts recognized in other comprehensive income and losses related to the subsidiary, the consolidated company accounting treatment must be followed by the direct disposal of related assets or liabilities with the consolidated company and the basis is the same.

B. Subsidiaries included in the consolidated financial statements:

• D. Adjustments for subsidiaries with different balance sheet dates: None.

• E. Significant restrictions: None.

• F. Subsidiaries that have non-controlling interests that are material to the Group: None.

15

• (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 realized, 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 realized 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.

  • (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) Foreign currency

When each entity prepares financial reports, transactions in currencies other than the individual's functional currency (foreign currency) are converted into functional currency records based on the exchange rate on the transaction day.

Monetary items in foreign currencies are translated at the closing exchange rate on each balance sheet date. The exchange difference arising from the currency items of delivery or the conversion of currency items is recognized in the current period profit and loss.

The fair value of foreign currency non-monetary items is used to determine the exchange rate on the day of fair value rate conversion, the resulting exchange difference is listed in the current profit and loss, but if the change in fair value is recognized in other comprehensive gains and losses, the resulting conversion difference is listed in other comprehensive gains and losses.

Non-monetary items in foreign currencies as measured by historical cost are converted at the exchange rate on the transaction date and will not be converted again.

When preparing the consolidated financial report, the assets and liabilities of foreign operating organizations (including subsidiaries in the country where they operate or whose currency is different from that of the company) are converted into New Taiwan dollars at the exchange rate on each balance sheet date. The income and expense items are converted at the average exchange rate of the current period. The resulting exchange difference is listed in other comprehensive profit and loss, and accumulated under the equity of the conversion difference of the foreign operation’s financial statements.

If the consolidated company disposes of all the rights and interests of the foreign operation, the accumulated exchange difference related to the foreign operations will be reclassified to profit or loss. If the partial disposal of the subsidiaries of the foreign operation does not result in the loss of control, the accumulated exchange difference is re-attributed to the subsidiary’s non-controlling interests and is not recognized as a profit or loss.

16

(6) Inventories

Inventories are stated at the lower of cost and net realisable value. Cost is determined using the weighted-average method. 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.

(7) Non-current assets classified as held for sale

The carrying amount of non-current assets is expected to be mainly through sales transactions rather than continued use. When closed, it is classified as pending sale. Non-current assets that meet this classification must be available for immediate sale in their current state, and their sale must be highly probable. When the appropriate level of management commits to the plan to sell the asset, and the sale transaction is expected to start from the classification date when completed within one year, it will meet the sale as highly likely.

Non-current assets classified as pending for sale are measured at the lower of the book value and fair value less the cost of sale, and depreciation is stopped for such assets.

(8) Property, plant and equipment

Real estate, plant and equipment are recognized at cost, and subsequently cost minus accumulated depreciation and the amount after the accumulated impairment loss is measured.

The real property, plant and equipment under construction are the cost minus the accumulated impairment loss and the amount is recognized. Cost includes professional service fees and borrowing costs that meet the capitalization conditions. When these assets are completed and reach the expected state of use, they are classified into real estate, plant and equipment of the appropriate categories of equipment and start depreciation.

Except for self-owned land, which is not depreciated, the rest of the real estate, plant and equipment will be depreciated on a straight-line basis within the service life of each significant part. The consolidated company is at least to review the estimated service life, residual value and depreciation method at the end of each year, and postpone the impact of changes in applicable accounting estimates.

When real estate, plant and equipment are delisted, the difference between the net disposal price and the book value of the asset is recognized in profit and loss.

(9) Investment real estate

Investment real estate refers to real estate held for the purpose of earning rent or capital appreciation or both (including right-of-use assets that meet the definition of investment real estate). Investment real estate also includes land that has not yet been determined for future use.

Self-owned investment real estate is initially measured at cost (including transaction costs), and subsequently measured at the amount of cost minus accumulated depreciation and accumulated impairment losses.

The investment real estate acquired by the lease is initially measured at cost (including the original measurement amount of the lease liability and the lease payment paid before the lease start date), and subsequently measured at the amount after the cost minus the accumulated depreciation and accumulated impairment losses, and the lease liability is adjusted again. All investment real estate is depreciated on a straight-line basis. Real estate, plant and equipment are transferred to investment real estate on the book amount at the end of self-use.

When investment real estate is delisted, the difference between the net disposal price and the asset's book value is recognized in profit and loss.

17

(10) Impairment of non-financial assets

The consolidated company assesses on each balance sheet date whether there are any indications that real property, plant and equipment, right-of-use assets, and intangible assets may have been impaired. If there is any sign of impairment, estimate the recoverable amount of the asset. If the recoverable amount of an individual asset cannot be estimated, the consolidated company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

The recoverable amount is the higher of the fair value less the cost of sale and its use value. If the recoverable amount of an individual asset or cash-generating unit is lower than its book value, the book value of the asset or cash-generating unit is reduced to its recoverable amount, and the impairment loss is recognized in profit and loss.

When the impairment loss is subsequently reversed, the carrying amount of the asset or cashgenerating unit is adjusted to the revised recoverable amount, but the increased carrying amount does not exceed the asset or cash-generating unit if the impairment is not recognized in the previous year which the book value determined at the time of the loss (minus amortization or depreciation). The reversal of the impairment loss is recognized in the profit and loss.

(11) Financial instruments

Financial assets and financial liabilities are recognized on the consolidated balance sheet of the consolidated company which becomes one of the contractual terms of the instrument.

When financial assets and financial liabilities are initially recognized, if financial assets or financial liabilities are not measured at fair value through profit and loss, they are directly attributable to the acquisition or issuance of financial assets or financial liabilities at fair value plus the transaction cost measurement. Directly attributable to the acquisition or issuance of financial assets or financial liabilities measured at fair value through profit and loss is immediately recognized as profit and loss.

1. Financial assets

Conventional transactions of financial assets are recognized and delisted by accounting on the transaction date.

• (1) Type of measurement

The types of financial assets held by the consolidated company are financial assets measured at amortized cost and equity instruments measured at fair value through other comprehensive gains and losses.

• A. Financial assets measured at amortized cost

If the financial assets invested by the consolidated company meet the following two conditions, they are classified as financial assets measured at amortized cost:

• (a) It is held under a certain business model, the purpose of which is to hold financial assets

• (b) The contract terms generate cash flows on a specific date, and these cash flows are completely to collect contractual cash flows; and to pay the principal and interest on the amount of principal in circulation.

Financial assets measured at amortized cost (including cash and cash equivalents, accounts receivable at amortized cost, other receivables and other financial assets) are determined by the effective interest method after initial recognition The total book value is measured after deducting any impairment loss after amortization, and any foreign currency exchange gains and losses are recognized in profit and loss.

Except for the following two cases, interest income is the effective interest rate multiplied by the financial asset of total book amount:

• (a) For purchased or created credit-impaired financial assets, interest income is calculated by multiplying the effective interest rate after credit adjustment by the amortized cost of the financial asset.

18

• (b) For financial assets that are not purchased or original credit impairment, but subsequently become credit impairment, you should be confident to calculate interest income by multiplying the effective interest rate by the amortized cost of the financial asset from the next reporting period after the impairment. Equivalent cash includes fixed deposits that are highly liquid and can be converted into fixed cash at any time within 3 months from the date of acquisition, and are used to meet short-term cash commitments.

• B. Through other comprehensive profit and loss equity instruments measured at fair value to invest in a merged company, at the time of initial recognition, an irrevocable choice may be made, which is not to hold for trading and is not recognized by the purchaser of the business merger or has the consideration. Instrument investment is designated to be measured at fair value through other comprehensive gains and losses.

• Equity instrument investments measured at fair value through other comprehensive gains and losses are measured at fair value, and subsequent changes in fair value are reported in other comprehensive gains and losses and accumulated in other equity. At the time of investment disposal, the accumulated profits and losses are directly transferred to retained earnings and are not reclassified as profits and losses.

The dividends of equity instrument investments measured at fair value through other comprehensive gains and losses are recognized in the profit and loss when the rights of the consolidated company to receive payments are established, unless the dividend clearly represents the recovery of part of the investment cost.

• (2) Impairment of financial assets

• A. The consolidated company assesses the impairment losses of financial assets (including accounts receivable) measured at amortized cost based on expected credit losses on each balance sheet date.

• B. Accounts receivable shall be recognized as an allowance loss based on the expected credit loss during the duration. For other financial assets, first assess whether the credit risk has increased significantly since the initial recognition. If there is no significant increase, the allowance loss is recognized based on the 12-month expected credit loss, and if it has increased significantly, it is recognized based on the lifetime expected credit loss Allowance for losses.

• C. Expected credit loss is the weighted average credit loss based on the risk of default. The 12month expected credit loss refers to the expected credit loss caused by the possible default event of the financial instrument within 12 months after the reporting date, and the lifetime expected credit loss represents the expected credit loss caused by all possible default events during the expected lifetime of the financial instrument. The impairment loss of all financial assets is reduced by the allowance account.

(3) Delisting of financial assets

The consolidated company only lapses in the contractual rights from the cash flow of financial assets. It has transferred the financial assets and almost all risks and reports of the ownership of the assets.

When transferring to other enterprises, the financial assets are only delisted. When the financial assets measured at the amortized cost are delisted as a whole, their book amount is the difference between the consideration received is recognized in profit and loss. When the equity instrument investment measured at fair value through other comprehensive gains and losses is declassified as a whole, the accumulated gains and losses are directly transferred to the retained earnings are not reclassified as profit or loss.

19

1. Financial liabilities and equity instruments

2. (1) Classification of liabilities or equity

The debt and equity instruments issued by the amalgamating company are classified as financial liabilities or equity based on the substance of the contractual agreement and the definition of financial liabilities and equity instruments.

An equity instrument refers to any contract that recognizes the remaining equity of the consolidated company after deducting all its liabilities from its assets. The equity instruments issued are recognized by the consolidated company after the acquired price deducting the cost of direct issuance.

• (2) Financial liabilities

Financial liabilities are not held for trading and are not designated as those measured at fair value through profit or loss (including payables). The initial recognition is based on fair value plus direct attributable transaction cost measurement; follow-up evaluation adopts effective interest rate method to amortize this measure.

• (3) Delisting of financial liabilities

The consolidated company delists financial liabilities when contractual obligations have been fulfilled, cancelled, or expired debt.

When excluding financial liabilities, the difference between its book value and the total consideration paid or payable (including any transferred non-cash assets or liabilities assumed) is recognized as profit and loss.

(12) Liability provision

When the consolidated company has current obligations (statutory or constructive obligations) due to past events, and is likely to be required to pay off the obligations, and the amount of the obligations can be reliably estimated, the liability provision shall be recognized. The amount recognized as a liability reserve is based on the risk and uncertainty of the obligation, and is the best estimate of the expenditure required to settle the obligation on the balance sheet date. The liability reserve is measured by discounting the estimated cash flow of the settlement obligation.

(13) Income recognition

After the consolidated company recognizes the performance obligations in the customer contract, it allocates the transaction price to each performance

obligations, and recognize income when each performance obligation is met.

Commodity sales revenue

1. Commodity sales revenue comes from the manufacture and sale of polarizers. Sales revenue is recognized when the control of the product is transferred to the customer, that is, when the product is delivered to the customer and the combined company has no outstanding performance obligations that may affect the customer's acceptance of the product. Because when the goods arrive at the customer's designated location, the customer has the right to set the price and use of the goods and bears the main responsibility for resale, and bears the risk of obsolescence and obsolescence of the goods, the merged company recognizes revenue and receivables at that point in time Accounts. The advance receipts received before the arrival of the goods are recognized as contract liabilities.

2. Commodity sales revenue is measured by the fair value of the consideration received or receivable, and deducted estimated customer returns, discounts and other similar discounts. The combined company estimates possible sales returns and discounts based on historical experience and other known reasons, and recognizes them accordingly refund liabilities and related rights to return products.

20

(14) Rent

The consolidated company assesses whether the contract belongs to (or contains) a lease on the date of contract establishment.

1. The merged company is the lessor

When the lease term is to transfer almost all the risks and rewards attached to the ownership of the asset to the lessee classifies it as a finance lease. All other leases are classified as operating lease. When the consolidated company subleases the right-of-use asset, the right-of-use asset (not the underlying asset) is used to determine the classification of the sublease. However, if the main lease is a short-term when leasing, the sublease is classified as an operating lease. Under operating leases, lease payments after deduction of lease incentives are recognized as income on a straight-line basis during the relevant lease period. The lease negotiation with the lessee is related to lease repair from the effective date of the change, it will be treated as a new lease.

1. The consolidated company is the lessee

2. Except for the lease payments of low-value underlying asset leases and short-term leases that are subject to the applicable recognition exemption, the lease payments are recognized as expenses during the lease period on a straight-line basis, and all other leases are opened in the lease. The right-of-use assets and lease liabilities are recognized on the inception date.

The right-of-use asset is initially measured at cost, which comprises the initial measurement of the lease liabilities, adjusted for any lease payments made at or before the commencement date, less any lease incentives received, plus any initial direct costs incurred and an estimate of costs needed to dismantle, remove and restore the underlying assets and the subsequent measures are measured at the cost after deducting the accumulated depreciation and accumulated impairment losses, and the remeasurement amount of the lease liability is adjusted.

Except for those that meet the definition of investment real estate, right-of-use assets are

separately expressed in the consolidated balance sheet, and the recognition and balance of right-ofuse assets that meet the definition of investment real estate, please refer to Note 4 (9) Accounting Policy for Investment Real Estate.

The right-of-use asset adopts a straight-line basis from the lease start date to the end of its useful life or the lease period expires, the earlier of the two shall be depreciated.

The lease liability was originally measured at the present value of the lease payment. If the implicit interest rate of the lease is easy to determine, the lease payment is discounted using that interest rate. If the interest rate is not easy to determine, use the lessee to increase the borrowing interest rate.

Subsequently, the lease liability is measured on the amortized cost basis using the effective interest method, and the interest expense is amortized during the lease period. If the lease period or the index or rate used to determine the lease payment changes resulting in a change in the future lease payment, the consolidated company will continue measure the lease liability and relatively adjust the right-of-use asset. However, if the book value of the right-of-use asset has been reduced to zero, the remaining remeasured amount is recognized in the profit and loss. For lease modifications that are not treated as separate leases, the scope of the lease is reduced The remeasurement of the lease liability is to reduce the right-of-use asset and recognize the profit and loss of the partial or full termination of the lease; the remeasurement of the lease liability for other modifications is to adjust the right-of-use asset, and the lease liability is separately expressed in the consolidated balance sheet.

21

The consolidated company and the lessor negotiated rents directly related to the COVID-19, adjusted the rents due before June 30, 2021, resulting in a decrease in rents. These negotiations did not materially change other lease terms. The consolidated company chooses to adopt practical expedients to handle all rental negotiations that meet the aforementioned conditions, and does not assess whether the negotiation is a lease modification, but recognizes the reduction of lease payments in the profit and loss when the concession event or situation occurs, and relatively reduces the lease debt.

(15) Employee benefits

Short-term employee benefits are measured by the expected non-discounted amount of cash paid, and are recognized as expenses when the relevant services are provided.

For the definite allocation plan, the amount of the retirement fund that should be allocated is recognized as the current pension expense on the basis of accrual. The advance payment is recognized as an asset within the scope of refundable cash or reduced future payments.

The net obligation under the definite benefit plan is calculated by discounting the amount of future benefits earned by the employee for the current or past services, and the current value of the definite benefit obligation on the balance sheet date minus the fair value of the plan assets. The net obligation to determine benefits is calculated by the actuary every year using the projected unit benefit method, and the discount rate is determined by referring to the market yield rate of high-quality corporate bonds that are consistent with the currency and period of the determined benefit plan on the balance sheet date; in high-quality corporate bonds For countries with no deep market, the market yield rate of government bonds (at the balance sheet date) is used. The remeasurement amount generated by the determined benefit plan is recognized in other comprehensive profit and loss in the current period and included in the retained surplus. The related expenses of the previous service cost are immediately recognized as a loss.

Resignation benefits are benefits provided when the employee's employment is terminated before the normal retirement date or when the employee decides to accept the company's welfare invitation in exchange for termination of employment. The consolidated company recognizes expenses when the offer for resignation benefits can no longer be revoked or when the relevant reorganization costs are recognized earlier, and it is not expected that the benefits that are fully paid off within 12 months after the balance sheet date should be granted discount.

(16) Income taxes

1. Current income tax

The consolidated company determines the current income (loss), based on which to calculate the payable (recoverable) income tax.

The undistributed surplus calculated in accordance with the provisions of the Income Tax Law of the Republic of China is subject to additional income tax, recognized by the resolution of the Shareholders’ annual meeting.

The adjustment of income tax payable in previous years is included in current income tax.

1. Deferred income tax

Deferred income tax is calculated based on the temporary difference between the book value of assets and liabilities and the tax basis for calculating taxable income.

22

Deferred income tax liabilities are generally recognized for all taxable temporary differences, while deferred income tax assets are recognized when there is likely to be taxable income for deduction of temporary differences or loss deductions.

Taxable temporary differences related to investment in subsidiaries are recognized as deferred income tax liabilities, but if the consolidated company can control the timing of the reversal of the temporary difference, and the temporary difference is likely to not revert in the foreseeable future except. The deductible temporary differences related to this type of investment are recognized as deferred income tax only if it is likely to have sufficient taxable income to realize the temporary difference, and within the scope of expected return in the foreseeable future assets.

The carrying amount of deferred income tax assets is reviewed on each balance sheet date, and the carrying amount is reduced for those that are no longer likely to have sufficient taxable income to recover all or part of their assets. Those that were not previously recognized as deferred income tax assets are also reviewed on each balance sheet date and are likely to generate taxable income for the recovery of all or part of their assets in the future, increase the carrying amount. Deferred income tax assets and liabilities are measured by the tax rate for the current period of expected debt settlement or asset realization. The tax rate is based on the tax rate and tax law that has been legislated or substantively legislated on the balance sheet date, and the deferred tax liabilities and assets are measured It reflects the tax consequences arising from the manner in which the consolidated company expects to recover or settle the book value of its assets and liabilities on the balance sheet date.

• 3.Current and deferred income tax

Current and deferred income taxes are recognized in profit or loss, but current and deferred income taxes related to items recognized in other comprehensive income or directly included in equity are recognized in other comprehensive profit or loss may be directly included in equity.

5. Critical Accounting Judgments and Key Sources of Estimation and Assumption Uncertainty

When the consolidated company adopts the accounting policies described in Note 4, for those who cannot easily obtain information about the carrying amounts of assets and liabilities from other sources, the management must base on historical experience and other relevant factors to make relevant judgments, estimates and assumptions. The estimates and related assumptions are based on historical experience and other factors deemed relevant. Actual results may differ from estimates. Estimates and basic assumptions are continuously reviewed. If the revision of the estimate only affects the current period, it shall be recognized in the current period of the revision of the accounting estimate. If the revision of the accounting estimate affects both the current period and the future period, it shall be recognized in the current period and the future period of the estimate revision. The main sources of uncertainties in major accounting judgments, estimates and assumptions of the consolidated company are as follows:

• (1) Evaluation of inventories

Since inventory must be priced at the lower of cost and net realizable value, the merging company must use judgment and estimation to determine the net realizable value of the inventory at the end of the financial reporting period. Due to the rapid changes in the industry, the consolidated company assesses the amount of inventory at the end of the financial reporting period due to normal depletion, obsolescence, or no market sales value, and offsets the inventory cost to the net realizable value. This inventory evaluation is mainly based on the product demand in a specific period in the future, which may cause major changes.

23

• (2) Estimated impairment of financial assets

The estimated impairment of accounts receivable is based on the assumption of default rate and expected loss rate of the consolidated company. The consolidated company considers historical experience, current market conditions and forward-looking information to make assumptions and select input values for impairment assessment. For important assumptions and input values used, please refer to Note 6 (4). If the actual future cash flow is less than expected, it may be incurred significant impairment losses.

• (3) Assessment of impairment of non-financial assets

In the process of asset impairment assessment, the consolidated company must rely on subjective judgments and determine the independent cash flow of a specific asset group, the number of years of asset durability, and the possible future income and expenses of a specific asset group based on the use of assets and industrial characteristics. Changes or estimated changes brought about by the company's strategy may cause significant impairment or reversal of recognized impairment losses in the future.

The assets of the consolidated company were recognized NT$153,385,000 and NT$10,054,000 in 2020 and 2019 respectively.

(4) Calculation of net definite benefit liabilities

When calculating and determining the present value of welfare obligations, the merging company must use judgments and estimates to determine relevant actuarial assumptions on the balance sheet date, including the discount rate and future salary growth rate, etc. Any change in actuarial assumptions may materially affect the determined benefit obligation of the consolidated company.

• (5) The realizability of deferred income tax assets

• Deferred income tax assets are recognized when there is likely to be sufficient taxable income in the future to deduct temporary differences. When assessing the feasibility of deferred income tax assets, significant accounting judgments and estimates of the management must be involved, including the expected future sales revenue growth and profit rate, tax exemption period, applicable income tax deductions and tax regulations and cost-effective assumption. Any changes in the global economic environment, industrial environment and laws and regulations may cause major adjustments to deferred income tax assets.

In addition, the consolidated company will gradually review the recoverable amount of accounts receivable to ensure that the accounts receivable that cannot be recovered have been properly deducted.

2. The consolidated company recognizes the allowance loss of accounts receivable based on the expected credit loss during the duration. The expected credit loss during the existence period takes into account the past default records of customers and the current financial situation, industrial economic situation, and also considers the overall economic and industrial outlook.

• (2) Interest rate risk: The decline in the interest rate of government bonds will increase the present

• value of the determined welfare obligation, but the debt investment return of the planned asset will also increase. The two are in conflict and the impact of fixed benefit liabilities has a partial offset effect.

The risk assessment of an individual customer is based on the consideration of the customer’s financial status, credit rating factors that may affect customers’ ability to make payments, such as structural ratings, internal credit ratings of the consolidated company, historical transaction records and current economic conditions. The consolidated company will also use certain credit enhancement tools at the right time, such as advance payment and credit insurance, etc., to reduce the credit risk of specific customers.

As of December 31, 2020 and 2019, the balance of accounts receivable of the top ten customers accounted for the balance of accounts receivable of the consolidated company, the percentages are 82% and 71%, respectively. The credit risk of the remaining accounts receivable is insignificant.

(2) Financial credit risk

The credit risks of bank deposits, fixed income investments and other financial instruments are measured and monitored by the financial department of the consolidated company. The performing parties are all creditworthy banks and financial institutions with investment grade and above Institutions, company organizations and government agencies, there are no major performance concerns, so there is no major credit risk.

1. Fair value of financial instruments

2. (1) Financial instruments measured by amortized cost (including cash and cash equivalents, financial assets measured by amortized cost, notes receivable, accounts receivable, other accounts receivable, other financial assets, guarantee deposit receivable, short-term loans, notes payable, accounts payable, other payables, long-term loans and deposit deposits) is a reasonable approximation of the fair value.

3. (2) When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

   • a. Level 1 inputs: Unadjusted quoted prices for identical assets or liabilities in active markets.

   • b. Level 2 inputs: Other than quoted prices included within Level 1, inputs are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

   • c. Level 3 inputs: Derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

4. (3) For financial instruments measured at fair value on December 31, 2020, and 2019, the consolidated company depends on the nature, characteristics, risks and fair value levels of assets and liabilities. The relevant information is as follows:

• (4) Valuation techniques and assumptions applied in fair value measurement The fair value of financial assets is determined in the following way: Since the investee company’s original investment date, the performance and operation of the investee company has not undergone any major changes, so the consolidated company uses the investment cost as the fair value estimated value.

• (5) There was no change in the fair value of financial assets in 2020 and 2019.

12.Others

The consolidated company began to turn losses into profits in 2012, but since 2016, due to the continuous mass production of the polarizing plate factory in mainland China and the economic cycle, the revenue and the gross profit decreased. In addition, the Tainan earthquake caused the disaster loss of the branch in Southern Taiwan Science Park and the lessee of the branch in Southern Taiwan Science Park terminated the lease and the Taiwan dollar have a negative impact on the appreciation of the U.S. dollar, resulting in losses. Face difficulties business environment, the consolidated company adopts the following measures to improve operating conditions and strengthen financial structure:

(1)Funding:

The Company applied to the Industrial Bureau of the Ministry of Economic Affairs on April 10, 2020, in accordance with the ”Key Points for the Ministry of Economic Affairs to Assist Enterprises in Handling Bank Credit and Debt Negotiations'', to assist in the negotiation of bank claims and debts, requesting that short-term credit extension periods be extended to December 7, 2021, and medium and long-term loans extended for one year. The bank was held a delegation meeting on June 19, 2020, and on November 17, 2020, the majority of creditor banks agreed through written consent that the short-term credit extension periods was extended to December 7, 2020 and the mid- and long-term loan repayment period was extended for one year. (Please refer to Note 6 (12), and 6 (16) description)

• (2) Operation:

At present, the gross profit margin of TV products is low and the number of orders is small. The main customers have better gross profit of polarizers for commercial displays and a higher proportion of estimated revenue, plus the contribution of high-margin polarizers for vehicles, so gross profit can still maintain 20 % Level. The company's policy is still to reduce the number of orders for low-margin products and to win orders from customers with high-margin products such as high weather resistant vehicle-mounted products to increase profitability, and to continue to develop new customers in the VR market.

• (3) Activate assets:

The consolidated company intends to dispose of the branch in Southern Taiwan Science Park, Pingzhen No. 2 Factory, Pingzhen R&D Building and Pingzhen No. 5 Factory. The resolution was approved by the board of directors on August 8, 2019 and September 12, 2019. The abovementioned real estate has been obtained the written consent of the creditor banks. Among them, the sale of the Pingzhen No. 5 Factory was signed on November 21, 2019, and the sale was completed on January 15, 2020. The sale and purchase contract of the branch in Southern Taiwan Science Park was signed on October 19, 2020, and the sale was completed on January 5, 2021. Please refer to Note 6 (7) for the explanation.

At present, the Chinese market still accounts for about 90% of the consolidated company's revenue. In addition to aggressively expanding customers, it also makes every effort to develop new products such as VR products. It is expected to increase revenue and gross profit. In terms of financial structure improvement, in addition to the NT$20 million allocated for the sinking fund monthly and NT$50 million allocated every six months, the activation of assets such as the disposal of the Pingzhen No. 2 Factory and the idle equipment is also the goal of the consolidated company at this stage. Through the above methods, we can reduce the balance of bank loans and the interest expenses, so as to improve the financial structure and sound operations.
