Summary of significant accounting policies | 4. Summary of significant accounting policies The significant accounting policies applied in the preparation of these accompanying consolidated financial statements are set out below. These policies have been consistently applied during the reported periods, unless otherwise stated. a) Statement of compliance The consolidated financial statements of the Group have been prepared in accordance with IFRSs as issued by the IASB. b) Basis of preparation (a) Except for the following items, the consolidated financial statements have been prepared under the historical cost convention: i) Financial assets at fair value through profit or loss (including derivative instruments). ii) Financial assets at fair value through other comprehensive income. iii) Defined benefit liabilities were recognized based on the net amount of pension fund assets less the present value of benefit obligation. (b) The preparation of the consolidated financial statements in conformity with IFRSs requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 4 dd). (c) These consolidated financial statements are presented in New Taiwan dollars (“NT$”), which is the Company’s functional currency. c) Basis of consolidation (a) Basis for preparation of consolidated financial statements: i) All subsidiaries are included in the Group’s consolidated financial statements. Subsidiaries are all entities controlled by the Group. The Group controls an entity when the Group is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Consolidation of subsidiaries begins from the date the Group obtains control of the subsidiaries and ceases when the Group loses control of the subsidiaries. ii) Transactions, balances and unrealized gains or losses on transactions between companies within the Group are eliminated. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Group. iii) Profit or loss and each component of other comprehensive income are attributed to the owners of the parent and to the non-controlling non-controlling non-controlling iv) Changes in a parent’s ownership interest in a subsidiary that do not result in the parent losing control of the subsidiary (transactions with non-controlling non-controlling v) When the Group loses control of a subsidiary, the Group remeasures any investment retained in the former subsidiary at its fair value. That fair value is regarded as the fair value on initial recognition of a financial asset or the cost on initial recognition of the associate or joint venture. Any difference between fair value and carrying amount is recognized in profit or loss. All amounts previously recognized in other comprehensive income in relation to the subsidiary are reclassified to profit or loss on the same basis as would be required if the related assets or liabilities were disposed of. That is, when the Group loses control of a subsidiary, all gains or losses previously recognized in other comprehensive income in relation to the subsidiary should be reclassified from equity to profit or loss, if such gains or losses would be reclassified to profit or loss when the related assets or liabilities are disposed of. (b) Subsidiaries included in the consolidated financial statements: Percentage of Ownership (%) December 31, Name of investor Name of investee Main business Location 2020 2021 Note The Company ChipMOS U.S.A., Inc. (“ChipMOS USA”) Marketing of semiconductors and electronic related products San Jose, USA 100 100 The Company ChipMOS TECHNOLOGIES (BVI) LTD.

(“ChipMOS Shanghai”) Marketing of semiconductors and electronic related products Shanghai, People’s Republic of China (“PRC”) 100 100 (c) Subsidiaries not included in the consolidated financial statements: None. (d) Adjustments for subsidiaries with different statements of financial position dates: Not applicable. (e) No significant restrictions on the ability of subsidiaries to transfer funds to parent company. (f) Subsidiaries that have non-controlling d) Foreign currency translation Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The consolidated financial statements are presented in NT$, which is the Company’s functional currency and the Group’s presentation currency. (a) Foreign currency transactions and balances i) Foreign currency transactions are translated into the functional currency using the exchange rates on the trade date or measurement date. Therefore, foreign exchange differences resulting from the settlement of such transactions are recognized in profit or loss in the period in which they arise. ii) Monetary assets and liabilities denominated in foreign currencies at the period end are re-translated re-translation iii) Non-monetary re-translated Non-monetary re-translated non-monetary iv) All foreign exchange differences are presented in the statement of comprehensive income under “Other gains and losses” by the nature of transactions. (b) Translation of foreign operations The operating results and financial position of all the group entities, associates that have different functional currency and presentation currency are translated into the presentation currency as follows: i) Assets and liabilities for each statements of financial position are translated at the exchange rates prevailing at the statements of financial position date; ii) Income and expenses for each statement of comprehensive income are translated at average exchange rates of that period; and iii) All exchange differences are recognized in other comprehensive income. e) Classification of current and non-current (a) Assets that meet one of the following criteria are classified as current assets: i) Assets arising from operating activities that are expected to be realized, or are intended to be sold or consumed within the normal operating cycle; ii) Assets held mainly for trading purposes; iii) Assets that are expected to be realized within 12 months from the statements of financial position date; iv) Cash and cash equivalents, excluding restricted cash and cash equivalents and those that are to be exchanged or used to pay off liabilities more than 12 months after the statements of financial position date. All assets that do not meet the above criteria are classified as non-current (b) Liabilities that meet one of the following criteria are classified as current liabilities: i) Liabilities that are expected to be settled within the normal operating cycle; ii) Liabilities arising mainly from trading activities; iii) Liabilities that are to be settled within 12 months from the statements of financial position date; iv) Liabilities for which the repayment date cannot be unconditionally extended to more than 12 months after the statements of financial position date. Liabilities bearing terms that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. All liabilities that do not meet the above criteria are classified as non-current f) Cash equivalents Cash equivalents refer to short-term, highly liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value (including time deposits with less than 3 months contract period). Time deposits that meet the above definition and are held for the purpose of meeting short-term cash commitments in operations are classified as cash equivalents. g) Financial assets at fair value through profit or loss (a) Financial assets at fair value through profit or loss are financial assets that are not measured at amortized cost or fair value through other comprehensive income. (b) On a regular way purchase or sale basis, financial assets at fair value through profit or loss are recognized and derecognized using settlement date accounting. (c) At initial recognition, the Group measures the financial assets at fair value and recognizes the transaction costs in profit or loss. The Group subsequently measures the financial assets at fair value, and recognizes the gain or loss in profit or loss. (d) The Group recognizes the dividend income when the right to receive such payment is confirmed, inflow of the future economic benefits associated with the dividend is probable to the Group and the amount of the dividend can be measured reliably. h) Financial assets at fair value through other comprehensive income (a) Financial assets at fair value through other comprehensive income comprise equity instruments which are not held for trading, and for which the Group has made an irrevocable election at initial recognition to recognize changes in fair value in other comprehensive income. (b) On a regular way purchase or sale basis, financial assets at fair value through other comprehensive income are recognized and derecognized using settlement date accounting. (c) At initial recognition, the Group measures the financial assets at fair value plus transaction costs. The Group subsequently measures the financial assets at fair value. The changes in fair value of equity instruments that were recognized in other comprehensive income are reclassified to retained earnings and are not reclassified to profit or loss following the derecognition of the investment. Dividends are recognized as income when the right to receive such payment is confirmed, inflow of the future economic benefits associated with the dividend is probable to the Group and the amount of the dividend can be measured reliably. i) Financial assets at amortized cost (a) Financial assets at amortized cost are those that meet all of the following criteria: i) The objective of the Group’s business model is achieved by collecting contractual cash flows. ii) The financial assets’ contractual cash flows represent solely payments of principal and interest. (b) The Group’s time deposits which do not fall under cash equivalents are those with a short maturity period and are measured at initial investment amount as the effect of discounting is immaterial. j) Accounts and notes receivable (a) Accounts and notes receivable entitle the Group a legal right to receive consideration in exchange for transferred goods or rendered services. (b) The short-term accounts and notes receivable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial. k) Impairment of financial assets For financial assets at amortized cost, at each reporting date, the Group recognizes the impairment provision for 12 months expected credit losses if there has not been a significant increase in credit risk since initial recognition or recognizes the impairment provision for the lifetime expected credit losses if such credit risk has increased since initial recognition after taking into consideration all reasonable and verifiable information that includes forecasts. On the other hand, for accounts receivable or contract assets that do not contain a significant financing component, the Group recognizes the impairment provision for lifetime expected credit losses. l) Derecognition of financial assets The Group derecognizes a financial asset when the contractual rights to receive the cash flows from the financial asset have expired. m) Inventories Inventories are initially recorded at standard costs. Cost is determined on a weighted-average cost basis. At the end of reporting period, the differences between actual costs and standard costs were allocated to inventories and cost of revenue based on an appropriate rate. Allocation of fixed production overheads is based on the normal operating capacity of the production facilities. Costs associated with underutilized capacity are expensed in the period that the cost occurs. Inventories are valued at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale. The item by item approach is used in raw materials. The amount of any write-down of inventories to net realizable value and all losses of inventories are recognized as an expense in the period the write-down or loss occurs. n) Investments accounted for using equity method – associates (a) Associates are all entities over which the Group has significant influence but not control. In general, it is presumed that the investor has significant influence, if an investor holds, directly or indirectly 20 percent or more of the voting power of the investee. Investments in associates are accounted for using the equity method and are initially recognized at cost. (b) The Group’s share of its associates’ post-acquisition profits or losses is recognized in profit or loss, and its share of post-acquisition movements in other comprehensive income is recognized in other comprehensive income. When the Group’s share of losses in an associate equals or exceeds its interests in the associate, including any other unsecured receivables, the Group does not recognize further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate. (c) When changes in an associate’s equity that are not recognized in profit or loss or other comprehensive income of the associate and such changes not affecting the Group’s ownership percentage of the associate, the Group recognizes the Group’s share of change in equity of the associate in “Capital surplus” in proportion to its ownership. (d) Unrealized gains on transactions between the Group and its associates are eliminated to the extent of the Group’s interests in the associates. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been adjusted where necessary to ensure consistency with the policies adopted by the Group. (e) In the case where an associate issues new shares and the Group does not subscribe or proportionately acquire the new shares, which results in a change in the Group’s ownership percentage of the associate while maintaining significant influence on the associate, then the Group will treat the transaction as deemed disposal and reclassify to profit or loss the proportion of the gain or loss previously recognized in other comprehensive income relating to that reduction in ownership interest where appropriate. (f) When the Group disposes of its investment in an associate, if it loses significant influence on this associate, the amounts previously recognized in other comprehensive income in relation to the associate are reclassified to profit or loss, on the same basis as would be required if the relevant assets or liabilities were disposed of. If it still retains significant influence on this associate, then the amounts previously recognized in other comprehensive income in relation to the associate are reclassified to profit or loss proportionately in accordance with the aforementioned approach. o) Property, plant and equipment (a) Property, plant and equipment are initially recorded at cost. Borrowing costs incurred during the construction period are capitalized. (b) Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to profit or loss during the financial period in which they are incurred. (c) Land is not depreciated. Other property, plant and equipment apply cost model and are depreciated using the straight-line method to allocate their cost over their estimated useful lives. Each part of an item of property, plant and equipment with a cost that is significant in relation to the total cost of the item must be depreciated separately. (d) The assets’ residual values, useful lives and depreciation methods are reviewed, and adjusted if appropriate, at each financial year-end. Buildings 5 to 51 years Machinery and equipment 2 to 8 years Tools 2 to 4 years Others 2 to 6 years p) Leasing arrangements (lessee) – (a) Leases are recognized as a right-of-use (b) Lease liabilities include the net present value of the remaining lease payments at the commencement date, discounted using the incremental borrowing interest rate. Lease payments are comprised of the following: i) Fixed payments, less any lease incentives receivable; ii) The exercise price of a purchase option, if the lessee is reasonably certain to exercise that option. The Group subsequently measures the lease liability at amortized cost using the interest method and recognizes interest expense over the lease term. The lease liability is remeasured and the amount of remeasurement is recognized as an adjustment to the right-of-use (c) At the commencement date, the right-of-use right-of-use right-of-use q) Impairment of non-financial The Group assesses at each statements of financial position date the recoverable amounts of those assets where there is an indication that they are impaired. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell or value in use. When the circumstances or reasons for recognizing impairment loss for an asset in prior years no longer exist or diminish, the impairment loss is reversed. The increased carrying amount due to reversal should not be more than what the depreciated or amortized historical cost would have been if the impairment had not been recognized. r) Loans Loans comprise long-term and short-term bank loans. Loans are recognized initially at fair value, net of transaction costs incurred. Loans are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized as interest expense in profit or loss over the period of the loans using the effective interest method. s) Accounts and notes payable (a) Accounts payable are liabilities for purchases of raw materials, goods or services and notes payable are those resulting from operating and non-operating (b) The short-term accounts and notes payable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial. t) Derecognition of financial liabilities A financial liability is derecognized when the obligation specified in the contract is either discharged or cancelled or expires. u) Provisions for deficiency compensation Provisions are recognized when the Group has a present legal or constructive obligation as a result of past events, and it is probable that an outflow of economic resources will be required to settle the obligation and the amount of the obligation can be reliably estimated. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation on the statements of financial position date, which is discounted using a pre-tax v) Employee benefits (a) Short-term employee benefits Short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in respect of service rendered by employees and should be recognized as expenses when the employees render service. (b) Pensions i) Defined contribution plans For defined contribution plans, the contributions are recognized as pension expenses when they are due on an accrual basis. Prepaid contributions are recognized as an asset to the extent of a cash refund or a reduction in future payments. ii) Defined benefit plans 1. Net obligation under a defined benefit plan is defined as the present value of an amount of pension benefits that employees will receive on retirement for their services with the Group in the current period or prior periods. The liability recognized in the statements of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the statements of financial position date less the fair value of plan assets. The net defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. The discount rate is determined by using the interest rates of government bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension liability. 2. Remeasurements arising on defined benefit plans are recognized in other comprehensive income in the period in which they arise and are recorded as retained earnings. 3. Past service costs are recognized immediately in profit or loss. (c) Termination benefits Termination benefits are employee benefits provided in exchange for the termination of employment as a result from either the Group’s decision to terminate an employee’s employment before the normal retirement date, or an employee’s decision to accept an offer of redundancy benefits in exchange for the termination of employment. The Group recognizes an expense as it can no longer withdraw an offer of termination benefits, or it recognizes related restructuring costs, whichever is earlier. Benefits that are expected to be due more than 12 months after statements of financial position date shall be discounted to their present value. (d) Employees’ compensation and directors’ remuneration Employees’ compensation and directors’ remuneration are recognized as expenses and liabilities, provided that such recognition is required under legal obligation or constructive obligation and those amounts can be reliably estimated. Any difference between the resolved amounts and the subsequently actual distributed amounts is accounted for as changes in estimates. If employee compensation is paid by shares, the Company calculates the number of shares based on the closing price at the previous day of the board meeting resolution. w) Employee share-based payments Restricted shares (a) Restricted shares issued to employees are measured at the fair value of the equity instruments granted at the grant date, and are recognized as compensation cost over the vesting period. (b) For restricted shares where those shares do not restrict distribution of dividends to employees and employees are not required to return the dividends received if they resign during the vesting period, the Group recognizes the fair value of the dividends received by employees who are expected to resign during the vesting period as a compensation cost at the date the dividends were declared. (c) For restricted shares where employees do not need to pay to acquire those shares, if an employee resigns during the vesting period, the Group will recover and retire those shares at no cost. x) Income tax (a) The income tax expense for the period comprises current and deferred tax. Income tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or items recognized directly in equity, in which cases the income tax is recognized in other comprehensive income or equity. (b) The current income tax expense is calculated on the basis of the tax laws enacted or substantively enacted at the statements of financial position date in the countries where the Group and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in accordance with applicable tax regulations. It establishes provisions where appropriate based on the amounts expected to be paid to the tax authorities. An additional income tax is levied on the unappropriated retained earnings and is recorded as income tax expense in the year the profit generated. (c) Deferred tax is recognized, using the balance sheet liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated statements of financial position. However, the deferred tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred tax is provided on temporary differences arising on investments in subsidiaries and associates, except where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is determined using tax rates (and laws) that have been enacted or substantially enacted at the statements of financial position date and are expected to apply when the related deferred tax asset is realized or the deferred tax liability is settled. (d) Deferred tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. At each statements of financial position date, unrecognized and recognized deferred tax assets are reassessed. (e) A deferred tax asset shall be recognized for the carryforward of unused tax credits resulting from equity investments to the extent that it is possible that future taxable profit will be available against which the unused tax credits can be utilized. (f) If a change in tax rate is enacted or substantively enacted, the Group recognizes the effect of the change immediately in the period in which the change occurs. The effect of the change on items recognized outside profit or loss is recognized in other comprehensive income or equity while the effect of the change on items recognized in profit or loss is recognized in profit or loss. y) Capital stock (a) Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares in net proceeds of tax are shown in equity as a deduction. (b) Where the Company repurchases the Company’s shares that have been issued, the consideration paid, including any directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the Company’s equity holders. Where such shares are subsequently reissued, the difference between their book value and any consideration received, net of any directly attributable incremental transaction costs and the related income tax effects, is included in equity attributable to the Company’s equity holders. z) Dividends Dividends are recorded in the Company’s financial statements in the period in which they are resolved by the Company’s shareholders. Cash dividends are recorded as liabilities; stock dividends are recorded as stock dividends to be distributed and are reclassified to ordinary shares on the effective date of new shares issuance. aa) Revenue recognition (a) The Group is primarily engaged in the customized assembly and testing services of high-integration and high-precision integrated circuits based on customer’s specification demand to create or enhance the product. When providing assembly and testing services, the Group considers: i) Customer controls the provided raw materials and the Group receives the instruction from the customer on providing assembly and testing services and subsequent treatments. ii) The Group provides assembly and testing services to create or enhance an asset which is solely provided and controlled by the customer. The Group has no right to transfer the asset for another use. As the asset ownership belongs to the customer, who bears the significant risk and rewards and rights on the use of the asset, the Group recognizes assembly and testing service revenue based on the progress towards completion of performance obligation during the service period. (b) The progress towards completion on assembly services, services for Liquid Crystal Display and other Flat-Panel Display Driver Semiconductors (“LCDD”) and Bumping are measured by the actual input costs relative to estimate total expected input costs. The progress towards completion on testing services is measured by the actual incurred testing volume. The Group provides assembly and testing services based on customer’s specification, thus, the input costs incurred to assembly and testing volume completed in testing services are not linear over the duration of these services. Customer payment on assembly and testing services is based on predetermined payment schedule. A contract asset is recognized when the Group provides services in excess of customer’s payment. bb) Government grants Government grants are recognized at their fair value only when there is reasonable assurance that the Group will comply with any conditions attached to the grants will be received. Government grants are recognized in profit or loss on a systematic basis over the periods in which the Group recognizes expenses for the related costs for which the grants are intended to compensate. Government grants related to property, plant and equipment are recognized as non-current cc) Operating segments Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The Group’s chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Chairman of the Board of Directors that makes strategic decisions. dd) Critical accounting judgments, estimates and key sources of assumption uncertainty The preparation of the accompanying consolidated financial statements requires management to make critical judgments in applying the Group’s accounting policies and make critical assumptions and estimates concerning future events. Assumptions and estimates may differ from the actual results and are continually evaluated and adjusted based on historical experience and other factors. Such assumptions and estimates have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year; and the related information is addressed below: Critical accounting estimates and assumptions - Revenue recognition The Group recognizes revenue from services for assembly, LCDD and Bumping based on the progress towards completion of performance obligation during the service period. The Group estimates total expected input costs based on historical experience and measures the progress towards completion by the actual input costs relative to the total expected input costs. |

The Group identifies, measures, and manages such risks by its policies and preferences. ii) The Group has established appropriate policies, procedures and internal controls for financial risk management. Before entering into significant financial transactions, a due approval process must be carried out by the Board of Directors based on related protocols and internal control procedures. The Group complies with its financial risk management policies at all times. iii) In order to minimize and manage financial risks, the Group’s overall risk management program focuses on analyzing, identifying, and evaluating financial risk factors that may potentially have adverse effects on the Group’s financial position, and provide feasible solutions to avoid those factors. (c) Significant financial risks and degrees of financial risks i) Market risk The Group’s market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risks comprise foreign currency risk, interest rate risk, and other price risks. In practice, the risk variable rarely changes individually, and the change of each risk variable is usually correlative. The following sensitivity analysis did not consider the interaction of each risk variable. Foreign exchange risk 1. The Group’s exposure to the risk of changes in foreign exchange rates relates primarily to the Group’s operating activities (when revenue or expense is denominated in a different currency from the Company’s and its subsidiaries’ functional currency) and the Group’s net investments in foreign operations. 2. The Group applies natural hedges by using accounts receivable and accounts payable denominated in the same currency. However, this natural hedge does not concur with the requirement for hedge accounting. Furthermore, as net investments in foreign operations are for strategic purposes, they are not hedged by the Group. 3. The Group’s foreign currency exposure gives rise to market risks associated with exchange rate movements against the NT dollar for cash and cash equivalents, accounts receivable, other receivables, bank loans, accounts payable and other payables. 4. The Group’s businesses involve some non-functional December 31, 2020 Foreign currency Exchange Carrying amount (Foreign currency: functional currency) Financial assets Monetary items US$000 175,840 28.4800 5,007,923 JPY000 137,635 0.2763 38,029 RMB000 6,838 4.3770 29,930 Non-monetary JPY000 948,270 0.2763 262,007 RMB000 690,178 4.3770 3,020,908 Financial liabilities Monetary items US$000 26,410 28.4800 752,157 JPY000 1,538,241 0.2763 425,016 December 31, 2021 Foreign currency Exchange Carrying amount (Foreign currency: functional currency) Financial assets Monetary items US$000 188,143 27.6800 5,207,798 JPY000 141,523 0.2405 34,036 RMB000 4,944 4.3440 21,477 Non-monetary JPY000 1,598,839 0.2405 384,521 RMB000 827,811 4.3440 3,596,012 Financial liabilities Monetary items US$000 53,042 27.6800 1,468,203 JPY000 1,089,668 0.2405 262,005 5. The total exchange losses, including realized and unrealized losses arising from significant foreign exchange variations on monetary items held by the Group for the years ended December 31, 2019, 2020 and 2021, amounted to NT$154,993 thousand, NT$355,255 thousand and NT$89,152 thousand, respectively. 6. Analysis of foreign currency market risk arising from significant foreign exchange variations: Year ended December 31, 2019 Sensitivity analysis Change in Effect on profit (NT$000) Effect on other Financial assets Monetary items US$000 5 % 282,365 — JPY000 5 % 3,682 — RMB000 5 % 1,334 — Financial liabilities Monetary items US$000 5 % 11,793 — JPY000 5 % 14,261 — Year ended December 31, 2020 Sensitivity analysis Change in Effect on profit (NT$000) Effect on other Financial assets Monetary items US$000 5 % 250,396 — JPY000 5 % 1,901 — RMB000 5 % 1,497 — Financial liabilities Monetary items US$000 5 % 37,608 — JPY000 5 % 21,251 — Year ended December 31, 2021 Sensitivity analysis Change in Effect on profit (NT$000) Effect on other Financial assets Monetary items US$000 5 % 260,390 — JPY000 5 % 1,702 — RMB000 5 % 1,074 — Financial liabilities Monetary items US$000 5 % 73,410 — JPY000 5 % 13,103 — Price risk 1. The Group’s financial instruments, which are exposed to price risk, are the financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income. To manage its price risk arising from investments in financial instruments, the Group diversifies its portfolio. Diversification of the portfolio is in accordance with the limits set by the Group. 2. The Group invests in beneficiary certificates and listed stocks issued by the domestic companies. The prices of equity securities would change due to change of the future value of investee companies. For the years ended December 31, 2019, 2020 and 2021, it is estimated that the prices of equity securities increase or decrease by 1%, with all other variables held constant, would increase or decrease the Group’s profit before income tax by nil, NT$531 thousand and NT$3,600 thousand, respectively. 3. The Group’s investments in financial instruments comprise foreign unlisted stocks and partnership. The prices of financial instruments would change due to different valuation models and assumptions used. Analysis related to the effect on profit or other comprehensive income if these assumptions change is provided in Note 43 b) (g). Interest rate risk on cash flow and fair value 1. Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Group’s exposure to the risk of changes in market interest rates relates primarily to the Group’s bank loans with floating interest rates. The Group manages its interest rate risk by having a balanced portfolio of fixed and variable rate bank loans. The Group reassesses the hedge management periodically to make sure it complies with the cost effectiveness. 2. The sensitivity analysis depends on the exposure of interest rate risk at the end of the reporting period. 3. Analysis of debt with floating interest rates is based on the assumption that the outstanding debt at the end of the reporting period is outstanding throughout the period. The degree of variation the Group used to report to internal management is increase or decrease of 1% in interest rates which is assessed as the reasonable degree of variation by the management. 4. For the years ended December 31, 2019, 2020 and 2021, it is estimated that a general increase or decrease of 1% in interest rates, with all other variables held constant, would decrease or increase the Group’s profit before income tax approximately by NT$90,660 thousand, NT$78,150 thousand and NT$102,489 thousand, respectively, mainly due to the Group’s floating rate on bank loans. ii) Credit risk 1. Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss, mainly resulted from its operating activities (primarily notes and accounts receivable) and from its financing activities (primarily deposits with banks and financial instruments). The Group is exposed to credit risk arising from the carrying amount of the financial assets recognized in the consolidated statements of financial position. 2. Each business unit performs ongoing credit evaluations of its debtors’ financial conditions according to the Group’s established policies, procedures and controls relating to customer credit risk management. The Group maintains an account for loss allowance based upon the available facts and circumstances, history of collection and write-off 3. Credit risk from balances with banks and financial institutions is managed by the Group’s finance unit in accordance with the Group’s policies. Transaction counterparty of the Group is determined through its internal controls policy. For banks and financial institutions, only parties rated above BBB+ by Taiwan Ratings are accepted. The probability of counterparty default is remote, so there is no significant credit risk. 4. The Group adopts the assumptions under IFRS 9 “Financial Instruments” and the default is deemed to have occurred when the contract payments are past due over 90 days. 5. The Group categorized contract assets, accounts receivable and other receivables by characteristics of credit risk and applied the simplified approach using loss rate methodology to estimate expected credit loss. 6. The Group referred to the forecastability of business monitoring indicators published by the ROC National Development Council to adjust the loss rate which is based on historical and current information when assessing the future default possibility of contract assets, accounts receivable and other receivables. As of December 31, 2020 and 2021 the loss rate methodologies are as follows: December 31, 2020 Contract Accounts Other receivables NT$000 NT$000 NT$000 Expected loss rate 0.030 % 0.030 % 0.030 % Total carrying amount 389,133 5,365,776 51,446 Loss allowance (117 ) (1,620 ) (10 ) December 31, 2021 Contract Accounts Other receivables NT$000 NT$000 NT$000 Expected loss rate 0.030 % 0.030 % 0.030 % Total carrying amount 400,375 6,346,156 86,895 Loss allowance (120 ) (1,910 ) (16 ) 7. Under the simplified approach, movements in relation to loss allowance for contract assets, accounts receivable, and other receivables are as follows: 2019 Contract assets Accounts Other receivables NT$000 NT$000 NT$000 January 1 (135 ) (2,141 ) (13 ) Provision for impairment loss — — (5 ) Reversal of impairment loss 21 790 — December 31 (114 ) (1,351 ) (18 ) 2020 Contract assets Accounts Other receivables NT$000 NT$000 NT$000 January 1 (114 ) (1,351 ) (18 ) Provision for impairment loss (3 ) (269 ) — Reversal of impairment loss — — 8 December 31 (117 ) (1,620 ) (10 ) 2021 Contract assets Accounts Other receivables NT$000 NT$000 NT$000 January 1 (117 ) (1,620 ) (10 ) Provision for impairment loss (3 ) (290 ) (6 ) December 31 (120 ) (1,910 ) (16 ) 8. The Group’s recorded financial assets at amortized cost include time deposits with contract period over three months and restricted bank deposits. Because of the low credit risk, expected credit losses for the period are measured through a loss allowance at an amount equal to the 12-month iii) Liquidity risk 1. The Group manages and maintains adequate cash and cash equivalents to finance the Group’s operations, and minimize the impact from cash flow fluctuations. The Group also monitors its debt financing plans to ensure it is in compliance with the financial covenants required under its loan agreements. 2. The primary source of liquidity for the Group is from bank loans. See Notes 15 and 18 for details of the unused credit lines of the Group as of December 31, 2020 and 2021. 3. The contractual undiscounted cash flows of notes payable, accounts payable and other payables due within one year and is equivalent to its carrying amount. Except for the aforementioned, the table below summarizes the maturity profile of the Group’s non-derivative December 31, 2020 Within 1 year 1 to 3 years 3 to 5 years Over Total NT$000 NT$000 NT$000 NT$000 NT$000 Non-derivative Long-term bank loans 846,401 3,558,597 2,198,717 1,487,808 8,091,523 Lease liabilities 145,594 160,146 54,689 718,752 1,079,181 Guarantee deposits — — — 21,670 21,670 991,995 3,718,743 2,253,406 2,228,230 9,192,374 December 31, 2021 Within 1 year 1 to 3 years 3 to 5 years Over 5 years Total NT$000 NT$000 NT$000 NT$000 NT$000 Non-derivative Short-term bank loans 733,523 — — — 733,523 Long-term bank loans 114,953 2,817,662 4,568,521 2,265,350 9,766,486 Lease liabilities 182,186 119,748 54,113 691,764 1,047,811 Guarantee deposits — — — 21,625 21,625 1,030,662 2,937,410 4,622,634 2,978,739 11,569,445 The difference between the floating interest rates and estimated interest rates will affect the non-derivative b) Fair value information (a) The different levels of inputs used in valuation techniques to measure fair value of financial and non-financial Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that can be accessed at the measurement date. An active market is a market in which trading for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Inputs other than quoted prices from Level 1 that are observable information for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability. The fair value of the Group’s investment in equity investment without active market is included in Level 3. (b) The carrying amounts of cash and cash equivalents, financial assets at amortized cost, contract assets, notes receivable, accounts receivable, other receivables, refundable deposits, bank loans, notes payable, accounts payable, other payables, lease liabilities and guarantee deposits are approximate to their fair values. (c) The related information of financial and non-financial i) The related information of natures of the assets and liabilities are as follows: December 31, 2020 Level 1 Level 2 Level 3 Total NT$000 NT$000 NT$000 NT$000 Assets Recurring fair value measurements Financial assets at fair value through profit or loss - Listed stocks 53,120 — — 53,120 - Foreign partnership interests — — 10,368 10,368 Financial assets at fair value through other comprehensive income - Foreign unlisted stocks — — 262,007 262,007 53,120 — 272,375 325,495 December 31, 2021 Level 1 Level 2 Level 3 Total NT$000 NT$000 NT$000 NT$000 Assets Recurring fair value measurements Financial assets at fair value through profit or loss - Listed stocks 359,960 — — 359,960 Financial assets at fair value through other comprehensive income - Foreign unlisted stocks — — 384,521 384,521 359,960 — 384,521 744,481 ii) The methods and assumptions the Group used to measure fair value are as follows: 1. The fair value of the Group’s listed stocks is measured by using the market quoted prices, which is categorized within Level 1 fair value. 2. Except for listed stocks with active markets, the fair value of the Group’s other financial instruments is measured by using valuation techniques or by reference to counterparty quotes. The fair value of financial instruments measured by using valuation techniques can be referred to current fair value of instruments with similar terms and characteristics in substance, discounted cash flow method or other valuation methods, including calculated by applying model using market information available at the consolidated statement of financial position date. 3. The Group’s financial instruments issued by foreign partnerships are measured by using the discounted cash flow method, which derives present value estimates by discounting expected future operating effectiveness and free cash flows projections. 4. The Group’s financial instruments issued by foreign companies are measured by the comparable company valuation (EV/EBITDA ratio and P/B ratio). 5. The Group takes into account adjustments for credit risks to measure the fair value of financial and non-financial (d) The following table shows the movements of Level 3 for the years ended December 31, 2020 and 2021: December 31, 2020 Debt Equity Total NT$000 NT$000 NT$000 January 1 11,038 121,808 132,846 Gains or losses recognized in profit or loss Recorded as non-operating (670 ) — (670 ) Gains or losses recognized in other comprehensive income Recorded as unrealized gains on valuation of financial assets at fair value through other comprehensive income — 140,199 140,199 December 31 10,368 262,007 272,375 December 31, 2021 Debt Equity Total NT$000 NT$000 NT$000 January 1 10,368 262,007 272,375 Gains or losses recognized in profit or loss Recorded as non-operating (941 ) — (941 ) Gains or losses recognized in other comprehensive income Recorded as unrealized gains on valuation of financial assets at fair value through other comprehensive income — 122,514 122,514 Sold in the period (9,427 ) — (9,427 ) December 31 — 384,521 384,521 (e) The Group performs the fair value measurements being categorized within Level 3 with assistance from specialist. Such assessment is to ensure the valuation results are reasonable by applying independent information to make results close to current market conditions, confirming the resource of information is independent, reliable and in line with other resources and represented as the exercisable price, and frequently calibrating valuation model, updating inputs used to the valuation model and making any other necessary adjustments to the fair value. (f) The following is the qualitative information and sensitivity analysis of changes in significant unobservable inputs under valuation model used in Level 3 fair value measurement: Fair value as of December 31, Valuation technique Significant unobservable Range (weighted Relationship of inputs to fair value NT$000 Non-derivative Foreign partnership interests 10,368 Discounted cash flow Discount 0.30 % The lower the discount rate, the higher the fair value Non-derivative Foreign unlisted stocks 262,007 Comparable companies Price to book 1.97 The higher the multiple, the higher the fair value Enterprise 12.00 The higher the multiple, the higher the fair value Discount for 15.80 % The higher the discount for lack of marketability, the lower the fair value Fair value as of December 31, Valuation technique Significant unobservable Range (weighted average Relationship of inputs to fair value NT$000 Non-derivative Foreign unlisted stocks 384,521 Comparable companies Price to book 3.46 The higher the multiple, the higher the fair value Enterprise 9.43 The higher the multiple, the higher the fair value Discount for 15.80 % The higher the discount for lack of marketability, the lower the fair value (g) The Group has carefully assessed the valuation models and assumptions used to measure fair value. However, use of different valuation models or assumptions may result in different measurement. The following is the effect of profit or loss or of other comprehensive income from financial assets categorized within Level 3 if the inputs used to valuation models have changed: December 31, 2020 Recognized in profit or loss Recognized in other Input Change Favorable change Unfavorable change Favorable change Unfavorable change NT$000 NT$000 NT$000 NT$000 Financial assets: Foreign partnership interests Discount rate Note — — — — Foreign unlisted stocks Price to book ratio multiple ± 1% — — 30 30 Enterprise value to EBITDA multiple ± 1% — — 2,153 2,153 Discount for lack of marketability ± 1% — — 3,142 3,084 — — 5,325 5,267 Note: Based on the Group’s assessment, change in input would not have significant impact on profit or loss or other comprehensive income.

Statement of compliance | a) Statement of compliance The consolidated financial statements of the Group have been prepared in accordance with IFRSs as issued by the IASB. |
Basis of preparation | b) Basis of preparation (a) Except for the following items, the consolidated financial statements have been prepared under the historical cost convention: i) Financial assets at fair value through profit or loss (including derivative instruments). ii) Financial assets at fair value through other comprehensive income. iii) Defined benefit liabilities were recognized based on the net amount of pension fund assets less the present value of benefit obligation. (b) The preparation of the consolidated financial statements in conformity with IFRSs requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 4 dd). (c) These consolidated financial statements are presented in New Taiwan dollars (“NT$”), which is the Company’s functional currency. |
Basis of consolidation | c) Basis of consolidation (a) Basis for preparation of consolidated financial statements: i) All subsidiaries are included in the Group’s consolidated financial statements. Subsidiaries are all entities controlled by the Group. The Group controls an entity when the Group is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Consolidation of subsidiaries begins from the date the Group obtains control of the subsidiaries and ceases when the Group loses control of the subsidiaries. ii) Transactions, balances and unrealized gains or losses on transactions between companies within the Group are eliminated. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Group. iii) Profit or loss and each component of other comprehensive income are attributed to the owners of the parent and to the non-controlling non-controlling non-controlling iv) Changes in a parent’s ownership interest in a subsidiary that do not result in the parent losing control of the subsidiary (transactions with non-controlling non-controlling v) When the Group loses control of a subsidiary, the Group remeasures any investment retained in the former subsidiary at its fair value. That fair value is regarded as the fair value on initial recognition of a financial asset or the cost on initial recognition of the associate or joint venture. Any difference between fair value and carrying amount is recognized in profit or loss. All amounts previously recognized in other comprehensive income in relation to the subsidiary are reclassified to profit or loss on the same basis as would be required if the related assets or liabilities were disposed of. That is, when the Group loses control of a subsidiary, all gains or losses previously recognized in other comprehensive income in relation to the subsidiary should be reclassified from equity to profit or loss, if such gains or losses would be reclassified to profit or loss when the related assets or liabilities are disposed of. (b) Subsidiaries included in the consolidated financial statements: Percentage of Ownership (%) December 31, Name of investor Name of investee Main business Location 2020 2021 Note The Company ChipMOS U.S.A., Inc. (“ChipMOS USA”) Marketing of semiconductors and electronic related products San Jose, USA 100 100 The Company ChipMOS TECHNOLOGIES (BVI) LTD.

(d) Adjustments for subsidiaries with different statements of financial position dates: Not applicable. (e) No significant restrictions on the ability of subsidiaries to transfer funds to parent company. (f) Subsidiaries that have non-controlling |
Foreign currency translation | d) Foreign currency translation Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The consolidated financial statements are presented in NT$, which is the Company’s functional currency and the Group’s presentation currency. (a) Foreign currency transactions and balances i) Foreign currency transactions are translated into the functional currency using the exchange rates on the trade date or measurement date. Therefore, foreign exchange differences resulting from the settlement of such transactions are recognized in profit or loss in the period in which they arise. ii) Monetary assets and liabilities denominated in foreign currencies at the period end are re-translated re-translation iii) Non-monetary re-translated Non-monetary re-translated non-monetary iv) All foreign exchange differences are presented in the statement of comprehensive income under “Other gains and losses” by the nature of transactions. (b) Translation of foreign operations The operating results and financial position of all the group entities, associates that have different functional currency and presentation currency are translated into the presentation currency as follows: i) Assets and liabilities for each statements of financial position are translated at the exchange rates prevailing at the statements of financial position date; ii) Income and expenses for each statement of comprehensive income are translated at average exchange rates of that period; and iii) All exchange differences are recognized in other comprehensive income. |
Classification of current and non-current assets and liabilities | e) Classification of current and non-current (a) Assets that meet one of the following criteria are classified as current assets: i) Assets arising from operating activities that are expected to be realized, or are intended to be sold or consumed within the normal operating cycle; ii) Assets held mainly for trading purposes; iii) Assets that are expected to be realized within 12 months from the statements of financial position date; iv) Cash and cash equivalents, excluding restricted cash and cash equivalents and those that are to be exchanged or used to pay off liabilities more than 12 months after the statements of financial position date. All assets that do not meet the above criteria are classified as non-current (b) Liabilities that meet one of the following criteria are classified as current liabilities: i) Liabilities that are expected to be settled within the normal operating cycle; ii) Liabilities arising mainly from trading activities; iii) Liabilities that are to be settled within 12 months from the statements of financial position date; iv) Liabilities for which the repayment date cannot be unconditionally extended to more than 12 months after the statements of financial position date. Liabilities bearing terms that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. All liabilities that do not meet the above criteria are classified as non-current |
Cash equivalents | f) Cash equivalents Cash equivalents refer to short-term, highly liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value (including time deposits with less than 3 months contract period). Time deposits that meet the above definition and are held for the purpose of meeting short-term cash commitments in operations are classified as cash equivalents. |
Financial assets at fair value through profit or loss | g) Financial assets at fair value through profit or loss (a) Financial assets at fair value through profit or loss are financial assets that are not measured at amortized cost or fair value through other comprehensive income. (b) On a regular way purchase or sale basis, financial assets at fair value through profit or loss are recognized and derecognized using settlement date accounting. (c) At initial recognition, the Group measures the financial assets at fair value and recognizes the transaction costs in profit or loss. The Group subsequently measures the financial assets at fair value, and recognizes the gain or loss in profit or loss. (d) The Group recognizes the dividend income when the right to receive such payment is confirmed, inflow of the future economic benefits associated with the dividend is probable to the Group and the amount of the dividend can be measured reliably. |
Financial assets at fair value through other comprehensive income | h) Financial assets at fair value through other comprehensive income (a) Financial assets at fair value through other comprehensive income comprise equity instruments which are not held for trading, and for which the Group has made an irrevocable election at initial recognition to recognize changes in fair value in other comprehensive income. (b) On a regular way purchase or sale basis, financial assets at fair value through other comprehensive income are recognized and derecognized using settlement date accounting. (c) At initial recognition, the Group measures the financial assets at fair value plus transaction costs. The Group subsequently measures the financial assets at fair value. The changes in fair value of equity instruments that were recognized in other comprehensive income are reclassified to retained earnings and are not reclassified to profit or loss following the derecognition of the investment. Dividends are recognized as income when the right to receive such payment is confirmed, inflow of the future economic benefits associated with the dividend is probable to the Group and the amount of the dividend can be measured reliably. |
Financial assets at amortized cost | i) Financial assets at amortized cost (a) Financial assets at amortized cost are those that meet all of the following criteria: i) The objective of the Group’s business model is achieved by collecting contractual cash flows. ii) The financial assets’ contractual cash flows represent solely payments of principal and interest. (b) The Group’s time deposits which do not fall under cash equivalents are those with a short maturity period and are measured at initial investment amount as the effect of discounting is immaterial. |
Accounts and notes receivable | j) Accounts and notes receivable (a) Accounts and notes receivable entitle the Group a legal right to receive consideration in exchange for transferred goods or rendered services. (b) The short-term accounts and notes receivable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial. |
Impairment of financial assets | k) Impairment of financial assets For financial assets at amortized cost, at each reporting date, the Group recognizes the impairment provision for 12 months expected credit losses if there has not been a significant increase in credit risk since initial recognition or recognizes the impairment provision for the lifetime expected credit losses if such credit risk has increased since initial recognition after taking into consideration all reasonable and verifiable information that includes forecasts. On the other hand, for accounts receivable or contract assets that do not contain a significant financing component, the Group recognizes the impairment provision for lifetime expected credit losses. |
Derecognition of financial assets | l) Derecognition of financial assets The Group derecognizes a financial asset when the contractual rights to receive the cash flows from the financial asset have expired. |
Inventories | m) Inventories Inventories are initially recorded at standard costs. Cost is determined on a weighted-average cost basis. At the end of reporting period, the differences between actual costs and standard costs were allocated to inventories and cost of revenue based on an appropriate rate. Allocation of fixed production overheads is based on the normal operating capacity of the production facilities. Costs associated with underutilized capacity are expensed in the period that the cost occurs. Inventories are valued at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale. The item by item approach is used in raw materials. The amount of any write-down of inventories to net realizable value and all losses of inventories are recognized as an expense in the period the write-down or loss occurs. |
Investments accounted for using equity method – associates | n) Investments accounted for using equity method – associates (a) Associates are all entities over which the Group has significant influence but not control. In general, it is presumed that the investor has significant influence, if an investor holds, directly or indirectly 20 percent or more of the voting power of the investee. Investments in associates are accounted for using the equity method and are initially recognized at cost. (b) The Group’s share of its associates’ post-acquisition profits or losses is recognized in profit or loss, and its share of post-acquisition movements in other comprehensive income is recognized in other comprehensive income. When the Group’s share of losses in an associate equals or exceeds its interests in the associate, including any other unsecured receivables, the Group does not recognize further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate. (c) When changes in an associate’s equity that are not recognized in profit or loss or other comprehensive income of the associate and such changes not affecting the Group’s ownership percentage of the associate, the Group recognizes the Group’s share of change in equity of the associate in “Capital surplus” in proportion to its ownership. (d) Unrealized gains on transactions between the Group and its associates are eliminated to the extent of the Group’s interests in the associates. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been adjusted where necessary to ensure consistency with the policies adopted by the Group. (e) In the case where an associate issues new shares and the Group does not subscribe or proportionately acquire the new shares, which results in a change in the Group’s ownership percentage of the associate while maintaining significant influence on the associate, then the Group will treat the transaction as deemed disposal and reclassify to profit or loss the proportion of the gain or loss previously recognized in other comprehensive income relating to that reduction in ownership interest where appropriate. (f) When the Group disposes of its investment in an associate, if it loses significant influence on this associate, the amounts previously recognized in other comprehensive income in relation to the associate are reclassified to profit or loss, on the same basis as would be required if the relevant assets or liabilities were disposed of. If it still retains significant influence on this associate, then the amounts previously recognized in other comprehensive income in relation to the associate are reclassified to profit or loss proportionately in accordance with the aforementioned approach. |
Property, plant and equipment | o) Property, plant and equipment (a) Property, plant and equipment are initially recorded at cost. Borrowing costs incurred during the construction period are capitalized. (b) Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to profit or loss during the financial period in which they are incurred. (c) Land is not depreciated. Other property, plant and equipment apply cost model and are depreciated using the straight-line method to allocate their cost over their estimated useful lives. Each part of an item of property, plant and equipment with a cost that is significant in relation to the total cost of the item must be depreciated separately. (d) The assets’ residual values, useful lives and depreciation methods are reviewed, and adjusted if appropriate, at each financial year-end. Buildings 5 to 51 years Machinery and equipment 2 to 8 years Tools 2 to 4 years Others 2 to 6 years |
Leasing arrangements (lessee) – right-of-use assets / lease liabilities | p) Leasing arrangements (lessee) – (a) Leases are recognized as a right-of-use (b) Lease liabilities include the net present value of the remaining lease payments at the commencement date, discounted using the incremental borrowing interest rate. Lease payments are comprised of the following: i) Fixed payments, less any lease incentives receivable; ii) The exercise price of a purchase option, if the lessee is reasonably certain to exercise that option. The Group subsequently measures the lease liability at amortized cost using the interest method and recognizes interest expense over the lease term. The lease liability is remeasured and the amount of remeasurement is recognized as an adjustment to the right-of-use (c) At the commencement date, the right-of-use right-of-use right-of-use |
Impairment of non-financial assets | q) Impairment of non-financial The Group assesses at each statements of financial position date the recoverable amounts of those assets where there is an indication that they are impaired. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell or value in use. When the circumstances or reasons for recognizing impairment loss for an asset in prior years no longer exist or diminish, the impairment loss is reversed. The increased carrying amount due to reversal should not be more than what the depreciated or amortized historical cost would have been if the impairment had not been recognized. |
Loans | r) Loans Loans comprise long-term and short-term bank loans. Loans are recognized initially at fair value, net of transaction costs incurred. Loans are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized as interest expense in profit or loss over the period of the loans using the effective interest method. |
Accounts and notes payable | s) Accounts and notes payable (a) Accounts payable are liabilities for purchases of raw materials, goods or services and notes payable are those resulting from operating and non-operating (b) The short-term accounts and notes payable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial. |
Derecognition of financial liabilities | t) Derecognition of financial liabilities |
Provisions for deficiency compensation | u) Provisions for deficiency compensation Provisions are recognized when the Group has a present legal or constructive obligation as a result of past events, and it is probable that an outflow of economic resources will be required to settle the obligation and the amount of the obligation can be reliably estimated. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation on the statements of financial position date, which is discounted using a pre-tax |
Employee benefits | v) Employee benefits (a) Short-term employee benefits Short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in respect of service rendered by employees and should be recognized as expenses when the employees render service. (b) Pensions i) Defined contribution plans For defined contribution plans, the contributions are recognized as pension expenses when they are due on an accrual basis. Prepaid contributions are recognized as an asset to the extent of a cash refund or a reduction in future payments. ii) Defined benefit plans 1. Net obligation under a defined benefit plan is defined as the present value of an amount of pension benefits that employees will receive on retirement for their services with the Group in the current period or prior periods. The liability recognized in the statements of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the statements of financial position date less the fair value of plan assets. The net defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. The discount rate is determined by using the interest rates of government bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension liability. 2. Remeasurements arising on defined benefit plans are recognized in other comprehensive income in the period in which they arise and are recorded as retained earnings. 3. Past service costs are recognized immediately in profit or loss. (c) Termination benefits Termination benefits are employee benefits provided in exchange for the termination of employment as a result from either the Group’s decision to terminate an employee’s employment before the normal retirement date, or an employee’s decision to accept an offer of redundancy benefits in exchange for the termination of employment. The Group recognizes an expense as it can no longer withdraw an offer of termination benefits, or it recognizes related restructuring costs, whichever is earlier. Benefits that are expected to be due more than 12 months after statements of financial position date shall be discounted to their present value. (d) Employees’ compensation and directors’ remuneration Employees’ compensation and directors’ remuneration are recognized as expenses and liabilities, provided that such recognition is required under legal obligation or constructive obligation and those amounts can be reliably estimated. Any difference between the resolved amounts and the subsequently actual distributed amounts is accounted for as changes in estimates. If employee compensation is paid by shares, the Company calculates the number of shares based on the closing price at the previous day of the board meeting resolution. |
Employee share-based payments | w) Employee share-based payments Restricted shares (a) Restricted shares issued to employees are measured at the fair value of the equity instruments granted at the grant date, and are recognized as compensation cost over the vesting period. (b) For restricted shares where those shares do not restrict distribution of dividends to employees and employees are not required to return the dividends received if they resign during the vesting period, the Group recognizes the fair value of the dividends received by employees who are expected to resign during the vesting period as a compensation cost at the date the dividends were declared. (c) For restricted shares where employees do not need to pay to acquire those shares, if an employee resigns during the vesting period, the Group will recover and retire those shares at no cost. |
Income tax | x) Income tax (a) The income tax expense for the period comprises current and deferred tax. Income tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or items recognized directly in equity, in which cases the income tax is recognized in other comprehensive income or equity. (b) The current income tax expense is calculated on the basis of the tax laws enacted or substantively enacted at the statements of financial position date in the countries where the Group and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in accordance with applicable tax regulations. It establishes provisions where appropriate based on the amounts expected to be paid to the tax authorities. An additional income tax is levied on the unappropriated retained earnings and is recorded as income tax expense in the year the profit generated. (c) Deferred tax is recognized, using the balance sheet liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated statements of financial position. However, the deferred tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred tax is provided on temporary differences arising on investments in subsidiaries and associates, except where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is determined using tax rates (and laws) that have been enacted or substantially enacted at the statements of financial position date and are expected to apply when the related deferred tax asset is realized or the deferred tax liability is settled. (d) Deferred tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. At each statements of financial position date, unrecognized and recognized deferred tax assets are reassessed. (e) A deferred tax asset shall be recognized for the carryforward of unused tax credits resulting from equity investments to the extent that it is possible that future taxable profit will be available against which the unused tax credits can be utilized. (f) If a change in tax rate is enacted or substantively enacted, the Group recognizes the effect of the change immediately in the period in which the change occurs. The effect of the change on items recognized outside profit or loss is recognized in other comprehensive income or equity while the effect of the change on items recognized in profit or loss is recognized in profit or loss. |
Capital stock | y) Capital stock (a) Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares in net proceeds of tax are shown in equity as a deduction. (b) Where the Company repurchases the Company’s shares that have been issued, the consideration paid, including any directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the Company’s equity holders. Where such shares are subsequently reissued, the difference between their book value and any consideration received, net of any directly attributable incremental transaction costs and the related income tax effects, is included in equity attributable to the Company’s equity holders. |
Dividends | z) Dividends Dividends are recorded in the Company’s financial statements in the period in which they are resolved by the Company’s shareholders. Cash dividends are recorded as liabilities; stock dividends are recorded as stock dividends to be distributed and are reclassified to ordinary shares on the effective date of new shares issuance. |
Revenue recognition | aa) Revenue recognition (a) The Group is primarily engaged in the customized assembly and testing services of high-integration and high-precision integrated circuits based on customer’s specification demand to create or enhance the product. When providing assembly and testing services, the Group considers: i) Customer controls the provided raw materials and the Group receives the instruction from the customer on providing assembly and testing services and subsequent treatments. ii) The Group provides assembly and testing services to create or enhance an asset which is solely provided and controlled by the customer. The Group has no right to transfer the asset for another use. As the asset ownership belongs to the customer, who bears the significant risk and rewards and rights on the use of the asset, the Group recognizes assembly and testing service revenue based on the progress towards completion of performance obligation during the service period. (b) The progress towards completion on assembly services, services for Liquid Crystal Display and other Flat-Panel Display Driver Semiconductors (“LCDD”) and Bumping are measured by the actual input costs relative to estimate total expected input costs. The progress towards completion on testing services is measured by the actual incurred testing volume. The Group provides assembly and testing services based on customer’s specification, thus, the input costs incurred to assembly and testing volume completed in testing services are not linear over the duration of these services. Customer payment on assembly and testing services is based on predetermined payment schedule. A contract asset is recognized when the Group provides services in excess of customer’s payment. |
Government grants | bb) Government grants Government grants are recognized at their fair value only when there is reasonable assurance that the Group will comply with any conditions attached to the grants will be received. Government grants are recognized in profit or loss on a systematic basis over the periods in which the Group recognizes expenses for the related costs for which the grants are intended to compensate. Government grants related to property, plant and equipment are recognized as non-current |
Operating segments | cc) Operating segments Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The Group’s chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Chairman of the Board of Directors that makes strategic decisions. |
Critical accounting judgments, estimates and key sources of assumption uncertainty | dd) Critical accounting judgments, estimates and key sources of assumption uncertainty The preparation of the accompanying consolidated financial statements requires management to make critical judgments in applying the Group’s accounting policies and make critical assumptions and estimates concerning future events. Assumptions and estimates may differ from the actual results and are continually evaluated and adjusted based on historical experience and other factors. Such assumptions and estimates have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year; and the related information is addressed below: Critical accounting estimates and assumptions - Revenue recognition The Group recognizes revenue from services for assembly, LCDD and Bumping based on the progress towards completion of performance obligation during the service period. The Group estimates total expected input costs based on historical experience and measures the progress towards completion by the actual input costs relative to the total expected input costs. |
