Independent Auditors’ Report

To Silicon Integrated Systems Corporation

Opinion

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

In our opinion, based on our audits and the reports of other auditors (please refer to the Other Matter – Making Reference to the Audits of Component Auditors section of our report), the parent company only financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and its financial performance and cash flows for the years ended December 31, 2020 and 2019, in conformity with the requirements of 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 auditing standards generally accepted in the Republic of China. Our responsibilities under those standards are further described in the Auditors’ 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 Accountant of the Republic of China (the “Norm”), and we have fulfilled our other ethical responsibilities in accordance with the Norm. Based on our audits and the reposts of other auditors, 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 judgment, were of most significance in our audit of 2020 parent company only financial statements. 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, and we do not provide a separate opinion on these matters.

Revenue recognition

The Company recognized NT$ 136,621 thousand as net sales for the year ended December 31, 2020. Sales of products is the main operating activity of the Company. Its sales regions include not only Taiwan but also Asia and other regions. Trade terms of sales of products under each sales order may be different. It is necessary for the Company to judge and determine the performance obligations and the timing of its satisfaction under each sales order. As a result, we determined the matter to be a key audit matter.

Our audit procedures include (but are not limited to) evaluating and testing the effectiveness of internal control which is related to the timing of revenue recognition; assessing the appropriateness of the accounting policy for revenue recognition; performing test of details on samples selected; tracing to relevant documentation of transactions, reviewing the significant terms of sales orders and agreements, identifying the performance obligations of the sales orders and agreements and timing of its satisfaction, performing cutoff procedures and reviewing sales allowance after the reporting date. Please refer to Note 4 and Note 6 in notes to the parent company only financial statements.

Non-financial asset impairment

The Company’s book value of property, plant and equipment amounted to NT$742, 862 thousand as of December 31, 2020, representing 4% of total assets. As there existed an impairment indicator of the Company’s cash-generating unit, the Company performed an impairment testing on the cashgenerating unit. After performing the testing, the Company concludes that the cash-generating unit’s net fair value is higher than its carrying amount and therefore no impairment loss is recognized. Since the estimate of net fair value involves management’s judgements and subjective assumptions, we determined the matter to be a key audit matter.

Our audit procedures include (but are not limited to) understanding and evaluating the management process related to assets impairment recognition and measurement, evaluating the reasonableness of the property, plant and equipment appraisal report, reviewing the calculation of the fair value of property, plant and equipment which is adopting the comparative method, and inspecting the evidence of the Company’s ownership of the perperty.

Please refer to Note 5 and Note 6 in notes to the parent company only financial statements.

Other Matter – Making Reference to the Audits of Component Auditors

We did not audit the financial statements of certain investee companies, which were audited by other auditors, whose reports thereon have been furnished to us, and our opinions expressed herein are based solely on the audit reports of the other auditors. The investment in these investee companies under equity method amounted to NT$144,111 thousand and NT$186,331 thousand, accounting for 1% and 2% of total assets as of December 31, 2020 and 2019, respectively. The related shares of losses recognized from these subsidiaries, associates and joint ventures under the equity method amounted to NT$71,392 thousand and NT$60,566 thousand, accounting for 28% and 28% of the net loss before tax for the years ended December 31, 2020 and 2019, respectively.

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 requirements of the Regulations Governing the Preparation of Financial Reports by Securities Issuers for such internal control as management determines is necessary to enable the preparation of the 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 ability to continue as a going concern of the Company, 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 audit committee, are responsible for overseeing the financial reporting process of the Company.

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

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.
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 internal control of the Company.
Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.
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 to continue as a going concern of the Company. 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.

Evaluate the overall presentation, structure and content of the parent company only financial statements, including the accompanying notes, and whether the parent company only financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company and its subsdiaries to express an opinion on the parent company only financial statements. We are responsible for the direction, supervision and performance of the group 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 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 2020 parent company only financial statements 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.

The amendments address the inconsistency between the requirements in IFRS 10 and IAS 28, in dealing with the loss of control of a subsidiary that is contributed to an associate or a joint venture. IAS 28 restricts gains and losses arising from contributions of nonmonetary assets to an associate or a joint venture to the extent of the interest attributable to the other equity holders in the associate or joint venture. IFRS 10 requires full profit or loss recognition on the loss of control of a subsidiary. IAS 28 was amended so that the gain or loss resulting from the sale or contribution of assets that constitute a business as defined in IFRS 3 “Business Combinations” between an investor and its associate or joint venture is recognized in full.

IFRS 10 was also amended so that the gain or loss resulting from the sale or contribution of a subsidiary that does not constitute a business as defined in IFRS 3 between an investor and its associate or joint venture is recognized only to the extent of the unrelated investors’ interests in the associate or joint venture.

(b) IFRS 17 “Insurance Contracts”

IFRS 17 provides a comprehensive model for insurance contracts, covering all relevant accounting aspects (including recognition, measurement, presentation and disclosure requirements). The core of IFRS 17 is the General (building block) Model, under this model, on initial recognition, an entity shall measure a group of insurance contracts at the total of the fulfilment cash flows and the contractual service margin. The fulfilment cash flows comprise of the following:

(1) estimates of future cash flows;
(2) discount rate: an adjustment to reflect the time value of money and the financial risks related to the future cash flows, to the extent that the financial risks are not included in the estimates of the future cash flows; and
(3) a risk adjustment for non-financial risk.

The carrying amount of a group of insurance contracts at the end of each reporting period shall be the sum of the liability for remaining coverage and the liability for incurred claims. Other than the General Model, the standard also provides a specific adaptation for contracts with direct participation features (the Variable Fee Approach) and a simplified approach (Premium Allocation Approach) mainly for short-duration contracts.

These are the amendments to paragraphs 69-76 of IAS 1 Presentation of Financial statements and the amended paragraphs related to the classification of liabilities as current or non-current.

(d) Narrow-scope amendments of IFRS, including Amendments to IFRS 3, Amendments to IAS 16, Amendments to IAS 37 and the Annual Improvements
A. Updating a Reference to the Conceptual Framework (Amendments to IFRS 3) The amendments updated IFRS 3 by replacing a reference to an old version of the Conceptual Framework for Financial Reporting with a reference to the latest version, which was issued in March 2018. The amendments also added an exception to the recognition principle of IFRS 3 to avoid the issue of potential “day 2” gains or losses arising for liabilities and contingent liabilities. Besides, the amendments clarify existing guidance in IFRS 3 for contingent assets that would not be affected by replacing the reference to the Conceptual Framework.
B. Property, Plant and Equipment: Proceeds before Intended Use (Amendments to IAS 16)

The amendments prohibit a company from deducting from the cost of property, plant and equipment amounts received from selling items produced while the company is preparing the asset for its intended use. Instead, a company will recognise such sales proceeds and related cost in profit or loss.

C. Onerous Contracts - Cost of Fulfilling a Contract (Amendments to IAS 37)

The amendments clarify what costs a company should include as the cost of fulfilling a contract when assessing whether a contract is onerous.

(e) Disclosure Initiative - Accounting Policies – Amendments to IAS 1

The amendments improve accounting policy disclosures that to provide more useful information to investors and other primary users of the financial statements.

(f) Definition of Accounting Estimates – Amendments to IAS 8

The amendments introduce the definition of accounting estimates and include other amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors to help companies distinguish changes in accounting estimates from changes in accounting policies.

The abovementioned standards and interpretations issued by IASB have not yet been endorsed by FSC at the date when the Company’s financial statements were authorized for issue, the local effective dates are to be determined by FSC. The remaining new or amended standards and interpretations have no material impact on the Company.

4. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(1) Statement of Compliance

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

(2) Basis of Preparation

According to article 21 of the Regulations, the profit or loss and other comprehensive income presented in the parent company only financial reports will be the same as the allocations of profit or loss and of other comprehensive income attributable to owners of the parent presented in the financial reports prepared on a consolidated basis, and the owners' equity presented in the parent company only financial reports will be the same as the equity attributable to owners of the parent presented in the financial reports prepared on a consolidated basis. Therefore, the investments in subsidiaries will be disclosed under “Investments accounted for using the equity method” in the parent company only financial report and change in value will be adjusted.

The parent company only financial statements have been prepared on a historical cost basis, except for financial instruments that have been measured at fair value. The parent company only financial statements are expressed in thousands of New Taiwan Dollars (“NT$”) unless otherwise stated.

(3) Foreign Currency Transactions

The parent company only financial statements are presented in NT$.

Transactions in foreign currencies are initially recorded by the Company’s functional currency rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the functional currency closing rate of exchange ruling at the reporting date. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined. Non-monetary items that are measured at historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions.

All exchange differences arising on the settlement of monetary items or on translating monetary items are taken to profit or loss in the period in which they arise except for the following:

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

A. Exchange differences arising from foreign currency borrowings for an acquisition of a qualifying asset to the extent that they are regarded as an adjustment to interest costs are included in the borrowing costs that are eligible for capitalization.
B. Foreign currency items within the scope of IFRS 9 “Financial Instruments” are accounted for based on the accounting policy for financial instruments.
C. Exchange differences arising on a monetary item that forms part of a reporting entity’s net investment in a foreign operation is recognized initially in other comprehensive income and reclassified from equity to profit or loss on disposal of the net investment.

When a gain or loss on a non-monetary item is recognized in other comprehensive income, any exchange component of that gain or loss is recognized in other comprehensive income. When a gain or loss on a non-monetary item is recognized in profit or loss, any exchange component of that gain or loss is recognized in profit or loss.

(4) Translation of Financial Statements in Foreign Currency
Each foreign operation of the Company determines its functional currency upon its primary economic environment and items included in the financial statements of each operation are measured using that functional currency. The assets and liabilities of foreign operations are translated into New Taiwan Dollars at the closing rate of exchange prevailing at the reporting date and their income and expenses are translated at an average rate for the period. The exchange differences arising on the translation are recognized in other comprehensive income. On the disposal of a foreign operation, the cumulative amount of the exchange differences relating to that foreign operation, recognized in other comprehensive income and accumulated in the separate component of equity, is reclassified from equity to profit or loss when the gain or loss on disposal is recognized. On the partial disposal of foreign operations that results in a loss of control, loss of significant influence or joint control but retaining partial equity is considered a disposal.

On the partial disposal of a subsidiary that includes a foreign operation that does not result in a loss of control, the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income is adjusted in “ investments accounted for using the equity method ” . In partial disposal of an associate or jointly controlled entity that includes a foreign operation that does not result in a loss of significant influence or joint control, only the proportionate share of the cumulative amount of the exchange differences recognized in other comprehensive income is reclassified to profit or loss.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

Any goodwill and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and expressed in its functional currency.

(5) Current and Non-Current Distinction

An asset is classified as current when:

A. The Company expects to realize the asset, or intends to sell or consume it, in its normal operating cycle.
B. The Company holds the asset primarily for the purpose of trading.
C. The Company expects to realize the asset within twelve months after the reporting period.
D. The asset is cash or cash equivalents unless the asset is restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period.

All other assets are classified as non-current.

A liability is classified as current when:

A. The Company expects to settle the liability in its normal operating cycle.
B. The Company holds the liability primarily for the purpose of trading.
C. The liability is due to be settled within twelve months after the reporting period.
D. The Company does not have an unconditional right to defer settlement of the liability for at least twelve months after the reporting period. 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.

All other liabilities are classified as non-current.

(6) Cash and Cash Equivalents

Cash and cash equivalents comprise cash on hand, demand deposits and short-term, highly liquid time deposits or investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, (including time deposits with original maturities of three months or less).

(7) Financial Instruments

Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of the instrument.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

Financial assets and financial liabilities within the scope of IFRS 9 “Financial Instruments” are recognized initially at fair value plus or minus, in the case of investments not at fair value through profit or loss, directly attributable transaction costs.

A. Financial instruments: Recognition and Measurement

The Company accounts for regular way purchase or sales of financial assets on the trade date.

The Company classifies financial assets as subsequently measured at amortized cost, fair value through other comprehensive income or fair value through profit or loss on the basis of:

(a) the Company’s business model for managing the financial assets and
(b) the contractual cash flow characteristics of the financial asset.

Financial assets measured at amortized cost

A financial asset is measured at amortized cost if both of the following conditions are met and presented as note receivables, trade receivables, financial assets measured at amortized cost and other receivables etc., on balance sheet as at the reporting date:

(a) the financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows and
(b) the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

Such financial assets are subsequently measured at amortized cost and is not part of a hedging relationship. A gain or loss is recognized in profit or loss when the financial asset is derecognized, through the amortization process or in order to recognize the impairment gains or losses.

Interest revenue is calculated by using the effective interest method. This is calculated by applying the effective interest rate to the gross carrying amount of a financial asset except for:

(a) Purchased or originated credit-impaired financial assets. For those financial assets, the Company applies the credit-adjusted effective interest rate to the amortized cost of the financial asset from initial recognition.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

(b) Financial assets that are not purchased or originated credit-impaired financial assets but subsequently have become credit-impaired financial assets. For those financial assets, the Company applies the effective interest rate to the amortized cost of the financial asset in subsequent reporting periods.

Financial asset measured at fair value through other comprehensive income

A financial asset is measured at fair value through other comprehensive income if both of the following conditions are met:

(a) the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets and
(b) the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

Recognition of gain or loss on a financial asset measured at fair value through other comprehensive income is described as below:

(a) A gain or loss on a financial asset measured at fair value through other comprehensive income is recognized in other comprehensive income, except for impairment gains or losses and foreign exchange gains and losses, until the financial asset is derecognized or reclassified.
(b) When the financial asset is derecognized the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss as a reclassification adjustment.
(c) Interest revenue is calculated by using the effective interest method. This is calculated by applying the effective interest rate to the gross carrying amount of a financial asset except for:
(i) Purchased or originated credit-impaired financial assets. For those financial assets, the Company applies the credit-adjusted effective interest rate to the amortized cost of the financial asset from initial recognition.
(ii) Financial assets that are not purchased or originated credit-impaired financial assets but subsequently have become credit-impaired financial assets. For those financial assets, the Company applies the effective interest rate to the amortized cost of the financial asset in subsequent reporting periods.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

Besides, at initial recognition, the Company makes an irrevocable election to present in other comprehensive income subsequent changes in the fair value of an investment in an equity instrument within the scope of IFRS 9 that is neither held for trading nor contingent consideration recognized by an acquirer in a business combination to which IFRS 3 applies. Amounts presented in other comprehensive income are not subsequently transferred to profit or loss (when disposal of such equity instrument, its cumulated amount included in other components of equity is transferred directly to the retained earnings) and should be recorded as financial assets measured at fair value through other comprehensive income on balance sheet. Dividends on such investment are recognized in profit or loss unless the dividends clearly represent a recovery of part of the cost of investment.

Financial assets measured at fair value through profit or loss

Financial assets were measured at amortized cost or measured at fair value through other comprehensive income only if they met particular conditions. All other financial assets were measured at fair value through profit or loss and presented on the balance sheet as financial assets measured at fair value through profit or loss.

Such financial assets are measured at fair value, the gains or losses resulting from remeasurement are recognized in profit or loss which includes any dividend or interest received on such financial assets.

B. Impairment of financial assets

The Company recognizes a loss allowance for expected credit losses on debt instrument investments measured at fair value through other comprehensive income and financial assets measured at amortized cost. The loss allowance on debt instrument investments measured at fair value through other comprehensive income is recognized in other comprehensive income and does not reduce the carrying amount in the statement of financial position.

The Company measures expected credit losses of a financial instrument in a way that reflects:

(a) an unbiased and probability-weighted amount that is determined by evaluating a range of possible outcomes;
(b) the time value of money; and
(c) reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

The loss allowance is measured as follows:

(a) At an amount equal to 12-month expected credit losses: the credit risk on a financial asset has not increased significantly since initial recognition or the financial asset is determined to have low credit risk at the reporting date. In addition, the Company measures the loss allowance for a financial asset at an amount equal to lifetime expected credit losses in the previous reporting period, but determines at the current reporting date that condition is no longer met.
(b) At an amount equal to the lifetime expected credit losses: the credit risk on a financial asset has increased significantly since initial recognition or financial asset that is purchased or originated credit-impaired financial asset.
(c) For trade receivables or contract assets arising from transactions within the scope of IFRS 15, the Company measures the loss allowance at an amount equal to lifetime expected credit losses.
(d) For financing lease receivable arising from transactions within the scope of IFRS 16, the Company measures the loss allowance at an amount equal to lifetime expected credit losses.

At each reporting date, the Company needs to assess whether the credit risk on a financial asset has been increased significantly since initial recognition by comparing the risk of a default occurring at the reporting date and the risk of default occurring at initial recognition. Please refer to Note 12 for further details on credit risk.

C. Derecognition of financial assets

A financial asset is derecognized when:

(a) The rights to receive cash flows from the asset have expired.
(b) The Company has transferred the asset and substantially all the risks and rewards of the asset have been transferred.
(c) The Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

On derecognition of a financial asset in its entirety, the difference between the carrying amount and the consideration received or receivable including any cumulative gain or loss that had been recognized in other comprehensive income, is recognized in profit or loss.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

D. Financial liabilities and equity

Classification between liabilities or equity

The Company classifies the instrument issued as a financial liability or an equity instrument in accordance with the substance of the contractual arrangement and the definitions of a financial liability, and an equity instrument.

Equity instruments

An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. The transaction costs of an equity transaction are accounted for as a deduction from equity to the extent they are incremental costs directly attributable to the equity transaction that otherwise would have been avoided.

Financial liabilities

Financial liabilities within the scope of IFRS 9 Financial Instruments are classified as financial liabilities at fair value through profit or loss or financial liabilities measured at amortized cost upon initial recognition.

Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss.

A financial liability is classified as held for trading if:

(a) It is acquired or incurred principally for the purpose of selling or repurchasing it in the near term.
(b) On initial recognition it is part of a portfolio of identified financial instruments that are managed together and for which there is evidence of a recent actual pattern of short-term profit-taking; or
(c) It is a derivative (except for a derivative that is a financial guarantee contract or a designated and effective hedging instrument).

If a contract contains one or more embedded derivatives, the entire hybrid (combined) contract may be designated as a financial liability at fair value through profit or loss; or a financial liability may be designated as at fair value through profit or loss when doing so results in more relevant information, because either:

SILICON INTEGRATED SYSTEMS CORPORATION NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued) (Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

(a) it eliminates or significantly reduces a measurement or recognition inconsistency; or
(b) a group of financial liabilities or financial assets and financial liabilities is managed and its performance is evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, and information about the Company is provided internally on that basis to the key management personnel.

Gains or losses on the subsequent measurement of liabilities held for trading including interest paid are recognized in profit or loss.

Financial liabilities at amortized cost

Financial liabilities measured at amortized cost include interest bearing loans and borrowings that are subsequently measured using the effective interest rate method after initial recognition. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the effective interest rate method amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or transaction costs.

Derecognition of financial liabilities

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires.

When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified (whether or not attributable to the financial difficulty of the debtor), such an exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability, and the difference in the respective carrying amounts and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss.

E. Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the balance sheet if, and only if, there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, or to realize the assets and settle the liabilities simultaneously.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

(8) Fair Value Measurement

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

A. in the principal market for the asset or liability; or

B. in the absence of a principal market, in the most advantageous market for the asset or liability.

The principal or the most advantageous market must be accessible to by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants in their economic best interest.

A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques which are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

(9) Inventories

Inventories are valued at lower of cost and net realizable value item by item.

Costs incurred in bringing each inventory to its present location and condition are accounted for as follows:

Raw materials — Purchase cost on first in first out.

Finished goods and work in progress — Stated at standard cost and the cost difference is allocated to the cost of goods sold and the inventory at the end of the period at the checkout, so that it is close to the weighted average cost valuation.

Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale.

Rendering of services is accounted in accordance with IFRS 15 but not within the scoping of inventories.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

(10)Investments accounted for using the equity method

An associate is an entity over which the Company has significant influence. A joint venture is a type of joint arrangement whereby the Company that has joint control of the arrangement has rights to the net assets of the joint venture.

Under the equity method, the investment in the associate or joint venture is carried in the balance sheet at cost and adjusted thereafter for the post-acquisition change in the Company’s share of net assets of the associate or joint venture. After the interest in the associate or joint venture is reduced to zero, additional losses are provided for, and a liability is recognized, only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of the associate or joint venture. Unrealized gains and losses resulting from transactions between the Company and the associate or joint venture are eliminated to the extent of the Company’s related interest in the associate or joint venture.

When changes in the net assets of an associate or joint venture occur and not those that are recognized in profit or loss or other comprehensive income and do not affect the Company’s percentage of ownership interests in the associate or joint venture, the Company recognizes such changes in equity based on its percentage of ownership interests. The resulting capital surplus recognized will be reclassified to profit or loss at the time of disposing the associate or joint venture on a pro rata basis.

When the associate or joint venture issues new shares, and the Company’s interest in an associate or joint venture is reduced or increased as the Company fails to acquire shares newly issued in the associate or joint venture proportionately to its original ownership interest, the increase or decrease in the interest in the associate or joint venture is recognized in capital surplus and investments accounted for using the equity method. When the interest in the associate or joint venture is reduced, the cumulative amounts previously recognized in other comprehensive income are reclassified to profit or loss or other appropriate items. The aforementioned capital surplus recognized is reclassified to profit or loss on a pro rata basis when the Company disposes the associate or joint venture.

The financial statements of the associate or joint venture are prepared for the same reporting period as the Company. Where necessary, adjustments are made to bring the accounting policies in line with those of the Company.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

The Company determines at each reporting date whether there is any objective evidence that the investment in the associate or an investment in a joint venture is impaired in accordance with IAS 28 “Investments in Associates and Joint Ventures”. If this is the case, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and its carrying value and recognizes the amount in the ‘share of profit or loss of an associate’ in the statement of comprehensive income in accordance with IAS 36 “Impairment of Assets”. In determining the value in use of the investment, the Company estimates:

(1)Its share of the present value of the estimated future cash flows expected to be generated by the associate or joint venture, including the cash flows from the operations of the associate or joint venture and the proceeds on the ultimate disposal of the investment; or
(2)The present value of the estimated future cash flows expected to arise from dividends to be received from the investment and from its ultimate disposal.

Because goodwill that forms part of the carrying amount of an investment in an associate or an investment in a joint venture is not separately recognized, it is not tested for impairment separately by applying the requirements for goodwill impairment testing in IAS 36 “Impairment of Assets”.

Upon loss of significant influence over the associate or joint venture, the Company measures and recognizes any retaining investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence and the fair value of the retaining investment and proceeds from disposal is recognized in profit or loss.

(11)Property, Plant and Equipment

Property, plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment loss, if any. Such cost includes the cost of dismantling and removing the item and restoring the site on which it is located and borrowing costs for construction in progress if the recognition criteria are met. 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 is depreciated separately. When significant parts of property, plant and equipment are required to be replaced in intervals, the Company recognizes such parts as individual assets with specific useful lives and depreciation. The carrying amount of those parts that are replaced is derecognized in accordance with the derecognition provisions of IAS 16 “Property, plant and equipment”. When a major inspection is performed, its cost is recognized in the carrying amount of the plant and equipment as a replacement if the recognition criteria are satisfied. All other repair and maintenance costs are recognized in profit or loss as incurred.

SILICON INTEGRATED SYSTEMS CORPORATION NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

Depreciation is calculated on a straight-line basis over the estimated economic lives of the following assets:

Buildings and facilities	3-50 years
Machinery equipment	3-5 years
Transportation equipment	5 years
Office equipment	3-5 years

An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset is recognized in profit or loss.

The assets’ residual values, useful lives and methods of depreciation are reviewed at each financial year end and adjusted prospectively, if appropriate, and are treated as changes in accounting estimates.

(12)Leases

The Company assesses whether the contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset for a period of time, the Company assesses whether the contract, throughout the period of use, has both of the following:

A. the right to obtain substantially all of the economic benefits from use of the identified asset; and
B. the right to direct the use of the identified asset.

For a contract that is, or contains, a lease, the Company accounts for each lease component within the contract as a lease separately from non-lease components of the contract. For a contract that contains a lease component and one or more additional lease or non-lease components, the Company allocates the consideration in the contract to each lease component on the basis of the relative stand-alone price of the lease component and the aggregate stand-alone price of the non-lease components. The relative stand-alone price of lease and non-lease components shall be determined on the basis of the price the lessor, or a similar supplier, would charge the Company for that component, or a similar component, separately. If an observable stand-alone price is not readily available, the Company estimates the stand-alone price, maximizing the use of observable information.

The Company as a lessee

Except for leases that meet and elect short-term leases or leases of low-value assets, the Company recognizes right-of-use asset and lease liability for all leases which the Company is the lessee of those lease contracts.

At the commencement date, the Company measures the lease liability at the present value of the lease payments that are not paid at that date. The lease payments are discounted using the interest rate implicit in the lease, if that rate can be readily determined. If that rate cannot be readily determined, the Company uses its incremental borrowing rate. At the commencement date, the lease payments included in the measurement of the lease liability comprise the following payments for the right to use the underlying asset during the lease term that are not paid at the commencement date:

A. fixed payments (including in-substance fixed payments), less any lease incentives receivable;
B. variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;
C. amounts expected to be payable by the lessee under residual value guarantees;
D. the exercise price of a purchase option if the Company is reasonably certain to exercise that option; and
E. payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.

After the commencement date, the Company measures the lease liability on an amortized cost basis, which is increasing the carrying amount to reflect interest on the lease liability by using an effective interest method; and reducing the carrying amount to reflect the lease payments made.

At the commencement date, the Company measures the right-of-use asset at cost. The cost of the right-of-use asset comprises:

A. the amount of the initial measurement of the lease liability;
B. any lease payments made at or before the commencement date, less any lease incentives received;
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.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

For subsequent measurement of the right-of-use asset, the Company measures the right-ofuse asset at cost less any accumulated depreciation and any accumulated impairment losses. That is, the Company measures the right-of-use assets applying a cost model.

If the lease transfers ownership of the underlying asset to the Company by the end of the lease term or if the cost of the right-of-use asset reflects that the Company will exercise a purchase option, the Company depreciates the right-of-use asset from the commencement date to the end of the useful life of the underlying asset. Otherwise, the Company depreciates the right-of-use asset from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term.

The Company applies IAS 36 “Impairment of Assets” to determine whether the right-of-use asset is impaired and to account for any impairment loss identified.

Except for leases that meet and elect short-term leases or leases of low-value assets, the Company presents right-of-use assets and lease liabilities in the balance sheet and presents interest expense separately from the depreciation charge associated with those leases in the income statement.

For short-term leases or leases of low-value assets, the Company elects to recognize the lease payments associated with those leases as an expense on either a straight-line basis over the lease term or another systematic basis.

The Company as a lessor

At inception of a contract, the Company classifies each of its leases as either an operating lease or a finance lease. A lease is classified as a finance lease if it transfers substantially all the risks and rewards incidental to ownership of an underlying asset. A lease is classified as an operating lease if it does not transfer substantially all the risks and rewards incidental to ownership of an underlying asset. At the commencement date, the Company recognizes assets held under a finance lease in its balance sheet and present them as a receivable at an amount equal to the net investment in the lease.

For a contract that contains lease components and non-lease components, the Company allocates the consideration in the contract applying IFRS 15.

The Company recognizes lease payments from operating leases as rental income on either a straight-line basis or another systematic basis. Variable lease payments for operating leases that do not depend on an index or a rate are recognized as rental income when incurred.

(13)Intangible Assets

Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is its fair value as at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses, if any. Internally generated intangible assets, excluding capitalized development costs, are not capitalized and expenditure is reflected in profit or loss for the year in which the expenditure is incurred.

The useful lives of intangible assets are assessed as either finite or indefinite.

Intangible assets with finite useful lives are amortized over the useful lives and assessed for impairment whenever there is an indication that the intangible assets may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each fiscal year. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset is accounted for by changing the amortization period or method, as appropriate, and is treated as changes in accounting estimates.

Intangible assets with indefinite useful lives are not amortized, but are tested for impairment annually, either individually or at the CGU level. The assessment of indefinite useful life is reviewed annually to determine whether the indefinite useful life continues to be supportable. If not, the change in useful life from indefinite to finite is made on a prospective basis.

Gains or losses arising from derecognition of an intangible asset are recognized in other operating income and expenses.

Research and development costs

Research costs are expensed as incurred. Development expenditures, on an individual project, are recognized as an intangible asset when the Company can demonstrate:

A. the technical feasibility of completing the intangible asset so that it will be available for use or sale;
B. its intention to complete and its ability to use or sell the asset;
C. how the asset will generate future economic benefits;
D. the availability of resources to complete the asset; and
E. the ability to measure reliably the expenditure during development.

SILICON INTEGRATED SYSTEMS CORPORATION

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

Following initial recognition of the development expenditure as an asset, the cost model is applied requiring the asset to be carried at cost less any accumulated amortization and accumulated impairment losses. During the period of development, the asset is tested for impairment annually. Amortization of the asset begins when development is complete and the asset is available for use. It is amortized over the period of expected future benefit.

Useful lives Internally generated or acquired	IPs	Computer software
	Finite(3 years) Acquired	Finite(10 years) Acquired

Abovementioned intangible assets are amortized on a straight-line basis over the estimated useful life.

(14)Impairment of Non-Financial Assets

The Company assesses at the end of each reporting period whether there is any indication that an asset in the scope of IAS 36 “Impairment of Assets” may be impaired. If any such indication exists, or when annual impairment testing for an asset is required, the Company estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s or cash-generating unit’s (“CGU”) fair value less costs to sell and its value in use and is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. Where the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

For assets excluding goodwill, an assessment is made at each reporting date as to whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. If such indication exists, the Company estimates the asset’s or CGU’s recoverable amount. A previously recognized impairment loss is reversed only if there has been an increase in the estimated service potential of an asset which in turn increases the recoverable amount. However, the reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

A CGU, or the groups of CGUs, to which goodwill has been allocated is tested for impairment annually at the same time, irrespective of whether there is any indication of impairment. If an impairment loss is to be recognized, it is first allocated to reduce the carrying amount of any goodwill allocated to the CGU (groups of CGUs), then to the other assets of the unit (groups of units) pro rata on the basis of the carrying amount of each asset in the unit (groups of units). Impairment losses relating to goodwill cannot be reversed in future periods for any reason.

An impairment loss of continuing operations or a reversal of such impairment loss is recognized in profit or loss.

(15)Treasury Shares

Own equity instruments which are reacquired (treasury shares) are recognized at cost and deducted from equity. Any difference between the carrying amount and the consideration is recognized in equity.

(16)Revenue Recognition

The Company’s revenue arising from contracts with customers mainly include sale of goods. The accounting policies for the Company’s types of revenues are explained as follows:

Sale of goods

The Company manufactures and sells merchandise. Sales are recognized when goods have been shipped and customers have obtained the control (the customer has the ability to direct the use of the goods and obtain substantially all of the remaining benefits from the goods). The main products of the Company are touch ICs and server and industrial computer ICs Sales transactions are usually accompanied by discounts. Therefore, revenues from these sales are recognized based on the price specified in the contract, net of the estimated volume discounts. Based on previous experience, the Company uses the expected value method to estimate volume discounts. However, revenues are only recognized to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Refund liability is also recognized during the period specified in the contract.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

The credit period of the Company’s sale of goods is from 30 to 90 days. For most of the contracts, when the Company transfers the goods to customers and has a right to an amount of consideration that is unconditional, these contracts are recognized as trade receivables. The period between the Company transfers the goods to customers and when the customers pay for that goods is usually short and has no significant financing component to the contract.

(17)Post-Employment Benefits

All regular employees of the Company are entitled to a pension plan that is managed by an independently administered pension fund committee. Fund assets are deposited under the committee’s name in the specific bank account and hence, not associated with the Company. Therefore, fund assets are not included in the Company’s parent company only financial statements.

For the defined contribution plan, the Company will make a monthly contribution of no less than 6% of the monthly wages of the employees subject to the plan. The Company recognizes expenses for the defined contribution plan in the period in which the contribution becomes due.

Post-employment benefit plan that is classified as a defined benefit plan uses the Projected Unit Credit Method to measure its obligations and costs based on actuarial assumptions. Remeasurements, comprising of the effect of the actuarial gains and losses, the effect of the asset ceiling (excluding net interest) and the return on plan assets, excluding net interest, are recognized as other comprehensive income with a corresponding debit or credit to retained earnings in the period in which they occur. Past service costs are recognized in profit or loss on the earlier of:

A. the date of the plan amendment or curtailment; and

B. the date that the Company recognizes related restructuring or termination costs.

Net interest is calculated by applying the discount rate to the net defined benefit liability or asset, both as determined at the start of the annual reporting period, taking account of any changes in the net defined benefit liability (asset) during the period as a result of contribution and benefit payment.

(18)Share-based Payment Transactions

The cost of equity-settled transactions between the Company and its employees is recognized based on the fair value of the equity instruments granted. The fair value of the equity instruments is determined by using an appropriate pricing model.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

The cost of equity-settled transactions is recognized, together with a corresponding increase in other capital reserves in equity, over the period in which the performance and/or service conditions are fulfilled. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Company’s best estimate of the number of equity instruments that will ultimately vest. The income statement expense or credit for a period represents the movement in cumulative expense recognized as at the beginning and end of that period.

No expense is recognized for awards that do not ultimately vest, except for equity-settled transactions where vesting is conditional upon a market or non-vesting condition, which are treated as vesting irrespective of whether or not the market or non-vesting condition is satisfied, provided that all other performance and/or service conditions are satisfied.

Where the terms of an equity-settled transaction award are modified, the minimum expense recognized is the expense as if the terms had not been modified, if the original terms of the award are met. An additional expense is recognized for any modification that increases the total fair value of the share-based payment transaction, or is otherwise beneficial to the employee as measured at the date of modification.

Where an equity-settled award is cancelled, it is treated as if it fully vested on the date of cancellation, and any expense not yet recognized for the award is recognized immediately. This includes any award where non-vesting conditions within the control of either the entity or the employee are not met. However, if a new award is substituted for the cancelled award, and designated as a replacement award on the date that it is granted, the cancelled and new awards are treated as if they were a modification of the original award, as described in the previous paragraph.

The dilutive effect of outstanding options is reflected as additional share dilution in the computation of diluted earnings per share.

The cost of restricted shares issued is recognized as salary expense based on the fair value of the equity instruments on the grant date, together with a corresponding increase in other capital reserves in equity, over the vesting period. The Company recognizes unearned employee salary which is a transitional contra equity account; the balance in the account will be recognized as salary expense over the passage of vesting period.

(19)Income Tax

Income tax expense (income) is the aggregate amount included in the determination of profit or loss for the period in respect of current tax and deferred tax.

Current income tax

Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities, using the tax rates and tax laws that have been enacted or substantively enacted by the end of the reporting period. Current income tax relating to items recognized in other comprehensive income or directly in equity is recognized in other comprehensive income or equity and not in profit or loss.

The additional income tax for undistributed earnings is recognized as income tax expense in the subsequent year when the distribution proposal is approved by the stockholders’ meeting.

Deferred tax

Deferred tax is provided on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.

Deferred tax liabilities are recognized for all taxable temporary differences, except:

A. where the deferred tax liability arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.
B. in respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, where the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred tax assets are recognized for all deductible temporary differences, carry forward of unused tax credits and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

A. where the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

B. in respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted at the reporting date. The measurement of deferred tax assets and deferred tax liabilities reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax relating to items recognized outside profit or loss is recognized outside profit or loss. Deferred tax items are recognized in correlation to the underlying transaction either in other comprehensive income or directly in equity. Deferred tax assets are reassessed at each reporting date and are recognized accordingly.

Deferred tax assets and deferred tax liabilities are offset, if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

5. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS

The preparation of the Company’s parent company only financial statements require management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures and the disclosure of contingent liabilities. However, uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods.

Estimates and assumptions

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date, that may cause a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below:

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

A. Impairment of non-financial assets

An impairment exists when the carrying value of an asset or CGU exceeds its recoverable amount, which is the higher of its fair value less costs to sell and its value in use. The fair value less costs to sell calculation is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date less incremental costs that would be directly attributable to the disposal of the asset or CGU. The value in use calculation is based on a discounted cash flow model. The main assumption is that the recoverable amount of the CGU is used, which may affect the result of its impairment test.

B. Income tax

Uncertainties exist with respect to the interpretation of complex tax regulations and the amount and timing of future taxable income. Given the wide range of international business relationships and the long-term nature and complexity of existing contractual agreements, differences arising between the actual results and the assumptions made, or future changes to such assumptions, could cause future adjustments to tax income and expense already recorded. The Company establishes provisions, based on reasonable estimates, for possible consequences of audits by the tax authorities of the respective countries in which it operates. The amount of such provisions is based on various factors, such as experience of previous tax audits and differing interpretations of tax regulations by the taxable entity and the responsible tax authority. Such differences of interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective company’s domicile.

Deferred tax assets are recognized for all carryforward of unused tax losses and unused tax credits and deductible temporary differences to the extent that it is probable that taxable profit will be available or there are sufficient taxable temporary differences against which the unused tax losses, unused tax credits or deductible temporary differences can be utilized. The amount of deferred tax assets determined to be recognized is based upon the likely timing and the level of future taxable profits and taxable temporary differences together with future tax planning strategies. Please refer to Note 6 for more details on unrecognized deferred tax assets of the Company as of December 31, 2020.

Defined benefits plan

The Company adopts a defined benefit plan in accordance with the Labor Standards Act of the R.O.C.

The Ministry of Labor is in charge of establishing and implementing the fund utilization plan in accordance with the Regulations for Revenues, Expenditures, Safeguard and Utilization of the Labor Retirement Fund. The pension fund is invested in-house or under mandation, based on a passive-aggressive investment strategy for long-term profitability. The Ministry of Labor establishes checks and risk management mechanism based on the assessment of risk factors including market risk, credit risk and liquidity risk, in order to maintain adequate manager flexibility to achieve targeted return without over-exposure of risk. With regard to utilization of the pension fund, the minimum earnings in the annual distributions on the final financial statement shall not be less than the earnings attainable from the amounts accrued from two-year time deposits with the interest rates offered by local banks. Treasury Funds can be used to cover the deficits after the approval of the competent authority. As the Company does not participate in the operation and management of the pension fund, no disclosure on the fair value of the plan assets categorized in different classes could be made in accordance with paragraph 142 of IAS 19. The Company expects to contribute NT$0 to its defined benefit plan during the 12 months beginning after December 31, 2020.

The weighted average duration of the defined benefit obligations was 11 years and 12 years as of December 31, 2020 and 2019, respectively.

The principal assumptions used in determining the Company’s defined benefit plan are as follows:

follows:
Discount rate Expected rate of salary increases	December 31,
	2020	2019
	0.500% 3.750%	0.750% 4.000%

Sensitivity analysis of significant assumptions is as follows:

$- 1,663 1,587 -	$1,596 - - 1,532	$- 2,184 2,085 -	$2,093 - - 2,010

The sensitivity analysis above is based on a change in a significant assumption (for example: change in discount rate or future salary), keeping all other assumptions constant. The sensitivity analysis may not be representative of an actual change in the defined benefit obligation as it is unlikely that changes in assumptions would occur in isolation of one another.

There was no change in the methods and assumptions used in preparing the sensitivity analysis compared to the previous period.

(10)Equities

A. Common stock

The Company’s authorized capital as of December 31, 2020 and 2019 was NT$18,000,000 thousand, divided into 1,800,000 thousand shares, each at a par value of NT$10.

When a company incurs no loss, it may distribute the capital surplus generated from the excess of the issuance price over the par value of share capital and donations. The distribution could be made in cash to its shareholders in proportion to the number of shares being held by each of them.

C. Treasury shares

During the period from May 11, 2018 to January 7, 2019, the Company purchased 26,000 thousand common shares in the amount of NT$250,065 thousand on the centralized securities exchange market.

On July 15, 2019, the Company retired 6,000 thousand common shares and the registration processes have been completed.

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

Pursuant to existing regulations, the Company is required to set aside additional special reserve equivalent to the earnings for the year or undistributed retained earnings for prior year according to the debit balance of the components of shareholders’ equity for the year (and prior year). For any subsequent reversal of other net deductions from shareholders’ equity, the amount reversed may be distributed.

According to the Company Act, the Company needs to set aside amount to legal reserve unless where such legal reserve amounts to the total paid-in capital. The legal reserve can be used to offset the deficit of the Company. When the Company incurs not loss, it may distribute the portion of legal reserve which exceeds 25% of the paid-in capital by issuing new shares or by cash in proportion to the number of shares being held by each of the shareholders.

Following the adoption of TIFRS, the FSC on April 6, 2012 issued Order No. FinancialSupervisory-Securities-Corporate-1010012865, which sets out the following provisions for compliance: On a public company's first-time adoption of the TIFRS, for any unrealized revaluation gains and cumulative translation adjustments (gains) recorded to shareholders’ equity that the company elects to transfer to retained earnings by application of the exemption under IFRS 1, the Company shall set aside an equal amount of special reserve. Following a company’s adoption of the TIFRS for the preparation of its financial reports, when distributing distributable earnings, it shall set aside to special reserve, from the profit/loss of the current period and the undistributed earnings from the previous period, an amount equal to “other net deductions from shareholders’ equity” for the current fiscal year, provided that if the Company has already set aside special reserve according to the requirements in the preceding point, it shall set aside supplemental special reserve based on the difference between the amount already set aside and other net deductions from shareholders’ equity. For any subsequent reversal of other net deductions from shareholders’ equity, the amount reversed may be distributed.

As of December 31, 2020 and 2019, special reserve set aside for the first-time adoption of TIFRS amounted to NT$0.

Details of the 2019 and 2018 earnings distribution and dividends per share as resolved by general shareholders’ meeting on June 10, 2020 and June 21, 2019, respectively, are as follows:

(2) Financial Risk Management Objectives and Policies

The Company’s principal financial risk management objective is to manage the market risk, credit risk and liquidity risk related to its operating activities. The Company identifies, measures and manages the aforementioned risks based on the Company’s policy and risk tendency.

The Company has established appropriate policies, procedures and internal controls for financial risk management. The plans for material treasury activities are reviewed by Board of Directors and Audit Committee in accordance with relevant regulations and internal controls. The Company complies with its financial risk management policies at all times.

(3) Market Risk

Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of the changes in market prices. Market prices comprise foreign currency risk, interest rate risk and other price risk. (Such as equity risk)

In practice, it is rarely the case that a single risk variable will change independently from other risk variables; there are usually interdependencies between risk variables. However, the sensitivity analysis disclosed below does not take into accounts the interdependencies between risk variables.

Foreign currency risk

The Company’s exposure to the risk of changes in foreign exchange rates relates primarily to the Company’s operating activities (when revenues or expenses are denominated in a different currency from the Company’s functional currency) and the Company’s net investments in foreign subsidiaries.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

Some receivables and payables are denominated in the same foreign currency, and it will result in economic hedging effect. Further, net investments in foreign operations are primarily for strategic purposes, and they are not hedged by the Company.

The Company's sensitivity analysis to foreign currency risk mainly focuses on foreign currency monetary items at the end of the reporting period. The Company’s foreign currency risk is mainly from the volatility in the exchange rates of US$. The sensitivity analysis is as follows:

When NTD appreciates or depreciates against USD by 1%, the profit for the years ended December 31, 2020 and 2019 decreases / increases by NT$537 thousand and NT$631 thousand, respectively.

Interest rate risk

Interest rate risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company’s exposure to the risk of changes in market interest rates relates primarily to the Company’s investment at variable interest rates. As a whole, the interest rates risk is minimal.

Equity price risk

The Company’s equity investments, including listed and unlisted equity securities, are exposed to market price risk arising from uncertainties of future values of equity securities. The Company’s investments in listed and unlisted equity securities are classified under financial assets at fair value through other comprehensive income. The Company manages the equity price risk through diversification and placing limits on individual and total equity investments. Reports on the equity portfolio are submitted to the Company’s senior management on a regular basis. The Company’s Board of Directors reviews and approves certain significant equity investments according to level of authority.

At the reporting date ended December 31, 2020 and 2019, a change of 1% in the price of the listed equity securities classified under equity instrument investments measured at fair value through other comprehensive income would have impact of NT$135,044 thousand and NT$47,380 thousand, respectively, on the equity attributable to the Company.

Please refer to Note 12(7) for sensitivity analysis information of other equity instruments or derivatives that are linked to such equity instruments whose fair value measurement is categorized under Level 3.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

(4) Credit Risk Management

Credit risk is the risk that counterparty will not meet its obligations under a contract, leading to a financial loss. The Company is exposed to credit risk from operating activities (primarily for trade receivables) and from its financing activities (including bank deposits and other financial instruments).

Customer credit risk is managed by each business unit subject to the Company’s established policy, procedures and controls relating to customer credit risk management. Credit limits are established for all customers based on their financial position, rating from credit rating agencies, historical experience, prevailing economic condition and the Company’s internal rating criteria, etc. Certain customer’s credit risk will also be managed by taking credit enhancing procedures, such as requesting for prepayment.

As of December 31, 2020 and 2019, receivables from top ten customers represented 97% and 96% of the total trade receivables of the Company, respectively. The credit concentration risk of other accounts receivables was insignificant.

The Company manages its exposure to credit risk arising from bank deposits, fixed income securities and other financial instruments in accordance with established group policies. Since the counter-parties are selected reputable financial institutions and companies, the Company believes its exposure to credit risk is not significant.

The Company adopted IFRS 9 to assess the expected credit losses. The measurement indicators of the Company are described as follows:

			Carryingamount	Carryingamount
			As of
Level of credit risk	Indicator	Measurement method for expected credit losses	December 31,	December 31,
			2020	2019
Simplified method (Note)	Note	Lifetime expected credit losses	$28,603	$24,325

Note: Includes trade receivables.

(5) Liquidity Risk Management

The Company’s objective is to maintain a balance between continuity of funding and flexibility through use of cash and cash equivalents, highly liquid equity investments and bank borrowings. The table below summarizes the maturity profile of the Company’s financial liabilities based on the contractual undiscounted payments and contractual maturity.

(6) Fair Value of Financial Instruments
A. The methods and assumptions applied in determining the fair value of financial instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following methods and assumptions were used by the Company to measure or disclose the fair values of financial assets and financial liabilities:

(a)The carrying amount of cash and cash equivalents, trade receivables, accounts payables and other current financial assets approximates their fair value due to their short maturities.
(b)For financial assets and liabilities traded in an active market with standard terms and conditions, their fair value is determined based on market quotation price (i.e. listed equity securities) at the reporting date.

SILICON INTEGRATED SYSTEMS CORPORATION

NOTES TO PARENT COMPANY ONLY FINANCIAL STATEMENTS-(Continued)

(Amounts are expressed in thousands of New Taiwan Dollars unless otherwise stated)

(c)Fair value of equity instruments without market quotations (i.e. unlisted equity securities) are estimated using the market method valuation techniques based on parameters such as prices based on market transactions of equity instruments of identical or comparable entities and other relevant information (for example, inputs such as discount for lack of marketability, P/E ratio of similar entities and Price-Book ratio of similar entities).
B. Fair value of financial instruments measured at amortized cost

The carrying amount of the Company’s financial assets measured at amortized cost approximates their fair value since short maturities.

C. Fair value recognized on the balance sheet

Please refer to Note 12(7) for fair value measurement hierarchy for financial instruments of the Company.

(7) Fair Value Measurement Hierarchy
A. Fair value measurement hierarchy

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, based on the lowest level input that is significant to the fair value measurement as a whole.

Level 1, 2 and 3 inputs are described as follows:

Level 1 – Quoted (unadjusted) market prices in active markets for identical assets or liabilities that the entity can access at the measurement date.
Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly or indirectly.

Level 3 – Unobservable inputs for the assets or liabilities.

For assets and liabilities that are recognized in the financial statements on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization at the end of each reporting period.
