Basis of preparation of financial statements and principal accounting policies | 2. Basis of preparation of financial statements and principal accounting policies a) Basis of preparation (a) These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”), International Accounting Standards (“IAS”), International Financial Reporting Interpretations Committee (“IFRIC”) interpretations and Standing Interpretations Committee (“SIC”) interpretations issued by the International Accounting Standards Board (“IASB”), (collectively, “IFRSs”). (b) 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. (c) These consolidated financial statements are presented in New Taiwan dollars (“NT$”), which is the Company’s functional currency. (d) The initial adoption of IFRS 9 “Financial Instruments” (“IFRS 9”) and IFRS 15 “Revenue from Contracts with Customers” (“IFRS 15”) is effective on January 1, 2018, the Group has elected to apply modified retrospective approach whereby the cumulative impact of the application was recognized as retained earnings or other equity interest as of January 1, 2018 and the financial statements for the year ended December 31, 2017 were not restated. The financial statements for the year ended December 31, 2017 were prepared in compliance with IAS 39 “Financial Instruments”, IAS 18 “Revenue” and relating interpretations. Please refer to Notes 39 and 40 for details of significant accounting policies. b) New and amended standards adopted by the group New Standards, Interpretations and Amendments Effective date issued by IFRS 16, “Leases” January 1, 2019 (a) IFRS 16 “Leases” (“IFRS 16”), supersedes IAS 17 “Leases” (“IAS 17”) and the related interpretations issued by the Standing Interpretation Committee. The standard requires lessees to recognize a right-of-use low-value (b) The Group has elected to apply IFRS 16 by not restating the comparative information (referred herein as the “simplified retrospective approach”) when applying IFRSs effective in 2019. Accordingly, the Group increased right-of-use (c) The Group has adopted the following practical expedients permitted by the standard at the date of initial application of IFRS 16: i) Reassessment as to whether a contract is, or contains, a lease is not required, instead, the application of IFRS 16 depends on whether or not the contracts were previously identified as leases applying IAS 17 and IFRIC 4 “Determining whether an Arrangement contains a Lease”. ii) The use of a single discount rate to a portfolio of leases with reasonably similar characteristics. iii) The accounting for operating leases whose period will end before December 31, 2019 as short-term leases and accordingly, rent expense of NT$ 28,126 thousand was recognized for the year ended 2019. (d) The Group calculated the present value of lease liabilities by using the incremental borrowing interest rate, ranging from 1.7895% to 3.9474%. (e) The reconciliation between operating lease commitments for the remaining lease payments under IAS 17 and lease liabilities recognized as of January 1, 2019, measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate is as follows: NT$000 Operating lease commitments disclosed by applying IAS 17 as of December 31, 2018 320,214 Add: Lease payable recognized under finance lease by applying IAS 17 as of December 31, 2018 17,792 Less: Short-term leases (28,121 ) Add: Adjustments as a result of a different treatment of extension and termination options 874,298 Total lease contracts amount recognized as lease liabilities by applying IFRS 16 on January 1, 2019 1,184,183 Incremental borrowing interest rate at the date of initial application 1.7895%~3.9474% Lease liabilities recognized as of January 1, 2019 by applying IFRS 16 884,275 Other Amendments to IFRSs not listed above are not expected to have a material impact on the Group in the current or future reporting periods and on foreseeable future transactions. c) New and revised International Financial Reporting Standards not yet adopted None. d) 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 businesses Location 2018 2019 The Company ChipMOS U.S.A., Inc. (“ChipMOS USA”) Research, development and marketing of semiconductors, circuits, and electronic related products San Jose, USA 100 100 The Company ChipMOS BVI Holding company British Virgin Islands 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 e) 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. f) 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 g) 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. h) 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. (i) 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. j) 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 bank 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. k) 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. l) 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. m) 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. n) 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. o) Investments in 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. p) 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 q) Leases Effective from 2019 Leasing arrangements (lessee) – right-of-use (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 Prior to 2019 Leased assets / operating leases (lessee) (a) Based on the terms of a lease contract, a lease is classified as a finance lease if the Group assumes substantially all the risks and rewards incidental to ownership of the leased asset. i) A finance lease is recognized as an asset and a liability at the lease’s commencement at the lower of the fair value of the leased asset or the present value of the minimum lease payments. ii) The minimum lease payments are apportioned between the finance charges and the reduction of the outstanding liability. The finance charges are allocated to each period over the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability. iii) Property, plant and equipment held under finance leases are depreciated over their estimated useful lives. If there is no reasonable certainty that the Group will obtain ownership at the end of the lease, the asset shall be depreciated over the shorter of the lease term and its useful life. (b) Payments made under an operating lease (net of any incentives received from the lessor) are recognized in profit or loss on a straight-line basis over the lease term. r) 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. s) 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. t) Accounts payable Accounts payable are liabilities for purchases of raw materials, goods or services. The short-term accounts payable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial. 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. 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 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) Issued capital (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 believes that aforementioned methods are the most appropriate manner to measure the satisfaction of performance obligation to customers because the input costs incurred to assembly and testing volume completed in testing services |

Retirement benefit plans | 26. Retirement benefit plans a) Defined benefit plans The Company has a defined benefit pension plan in accordance with the Labor Standards Act, covering all regular employees’ service years prior to the enforcement of the Labor Pension Act on July 1, 2005 and service years thereafter of employees who chose to continue to be subject to the pension mechanism under the Labor Standards Act. Under the defined benefit pension plan, two units are accrued for each year of service for the first 15 years and one unit for each additional year thereafter, subject to a maximum of 45 units. Pension benefits are based on the number of units accrued and the average monthly salaries and wages of the last 6 months prior to retirement. The Company contributes monthly an amount equal to 2% of the employees’ monthly salaries and wages to the pension fund deposited with the Bank of Taiwan, the trustee, under the name of the independent pension fund committee. Also, the Company would assess the balance in the aforementioned labor pension reserve account by the end of every year. If the account balance is insufficient to pay the pension calculated by the aforementioned method, to the employees expected to be qualified for retirement next year, the Company will make contributions to cover the deficit by March of following year. (a) The amounts recognized in the statements of financial position are as follows: December 31, December 31, NT$000 NT$000 Present value of defined benefit obligations (910,081 ) (901,159 ) Fair value of plan assets 389,316 421,052 Net defined benefit liability (520,765 ) (480,107 ) (b) Movements in net defined benefit liability are as follows: 2018 Present value of defined benefit Fair value of plan assets Net defined benefit liability NT$000 NT$000 NT$000 January 1 (838,543 ) 360,017 (478,526 ) Current services cost (382 ) — (382 ) Interest (expense) income (14,429 ) 6,291 (8,138 ) (853,354 ) 366,308 (487,046 ) Remeasurements: Return on plan assets (excluding amounts included in interest income or expense) — 8,145 8,145 Financial assumption movement effect (56,934 ) — (56,934 ) Experience adjustments (11,172 ) — (11,172 ) (68,106 ) 8,145 (59,961 ) Pension fund contribution — 26,242 26,242 Paid pension 11,379 (11,379 ) — December 31 (910,081 ) 389,316 (520,765 ) 2019 Present value of Fair value of plan assets Net defined benefit NT$000 NT$000 NT$000 January 1 (910,081 ) 389,316 (520,765 ) Current services cost (332 ) — (332 ) Interest (expense) income (11,170 ) 4,831 (6,339 ) (921,583 ) 394,147 (527,436 ) Remeasurements: Return on plan assets (excluding amounts included in interest income or expense) — 12,601 12,601 Financial assumption movement effect (27,993 ) — (27,993 ) Experience adjustments 36,308 — 36,308 8,315 12,601 20,916 Pension fund contribution — 26,413 26,413 Paid pension 12,109 (12,109 ) — December 31 (901,159 ) 421,052 (480,107 ) (c) The Bank of Taiwan was commissioned to manage the fund of the Company’s defined benefit pension plan in accordance with the fund’s annual investment and utilization plan and the “Regulations for Revenues, Expenditures, Safeguard and Utilization of the Labor Retirement Fund” (Article 6: The scope of utilization for the fund includes deposit in domestic or foreign financial institutions, investment in domestic or foreign listed, over-the-counter, two-year (d) The principal actuarial assumptions used were as follows 2018 2019 Discount rate 1.25 % 1.00 % Future salary increase 3.50 % 3.50 % Assumptions regarding future mortality are set based on actuarial advice in accordance with published statistics and experience in each territory. Because the main actuarial assumption changed, the present value of defined benefit obligations is affected. The analysis was as follows: Discount rate Future salary increase Increase Decrease Increase Decrease NT$000 NT$000 NT$000 NT$000 December 31, 2018 Effect on present value of defined benefit obligations (29,052 ) 30,430 29,692 (28,513 ) December 31, 2019 Effect on present value of defined benefit obligations (27,993 ) 29,284 28,501 (27,407 ) The sensitivity analysis above is based on a change in an assumption while holding all other assumptions constant. In practice, changes in some of the assumptions may be correlated. The method of sensitivity analysis and the method of calculating net defined benefit liability in the statements of financial position are the same. The methods and types of assumptions used in preparing the sensitivity analysis remain unchanged from previous period. (e) Expected contributions to the defined benefit pension plan of the Company for the year ending December 31, 2020 amounts to NT $ (f) As of December 31, 2019, the weighted average duration of that retirement plan is 12.8 years. The analysis of timing of the future pension payment is as follows: December 31, 2019 NT$000 Within 1 year 35,272 1-2 34,647 2-5 122,670 5-10 167,707 360,296 b) Defined contribution plans Effective from July 1, 2005, the Company established a defined contribution pension plan (“New Plan”) under the Labor Pension Act, covering all regular employees with ROC nationality. Under the New Plan, the Company contributes monthly an amount based on 6% of the employees’ monthly salaries and wages to the employees’ individual pension accounts at the Bureau of Labor Insurance. The benefits accrued are paid monthly or in lump sum upon termination of employment. The pension costs under defined contribution pension plans of the Company for the years ended December 31, 2018 and 2019 were NT$193,047 thousand and NT$187,502 thousand, respectively. |

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, 2018 Foreign currency Exchange Carrying amount (Foreign currency: functional currency) Financial assets Monetary items US$000 170,270 30.7150 5,229,843 JPY000 177,557 0.2782 49,396 RMB000 8,850 4.4720 39,577 Financial liabilities Monetary items US$000 18,230 30.7150 559,934 JPY000 2,436,140 0.2782 677,734 December 31, 2019 Foreign currency Exchange Carrying amount (Foreign currency: functional currency) Financial assets Monetary items US$000 188,369 29.9800 5,647,303 JPY000 266,819 0.2760 73,642 RMB000 6,197 4.3050 26,678 Financial liabilities Monetary items US$000 7,867 29.9800 235,853 JPY000 1,033,394 0.2760 285,217 5. The total exchange (loss) gain, including realized and unrealized (losses) gains arising from significant foreign exchange variations on monetary items held by the Group for the years ended December 31, 2018 and 2019, amounted to gain of NT$93,104 thousand and loss of NT$154,993 thousand, respectively. 6. Analysis of foreign currency market risk arising from significant foreign exchange variations: 2018 Change in Effect on profit Effect on other Financial assets Monetary items US$000 5 % 261,492 — JPY000 5 % 2,470 — RMB000 5 % 1,979 — Financial liabilities Monetary items US$000 5 % 27,997 — JPY000 5 % 33,887 — 2019 Change in Effect on profit 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 — 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’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 33 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, 2018 and 2019, 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 approximately by NT$98,220 thousand 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 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.

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 Note 25 for details of the unused credit lines of the Group as of December 31, 2018 and 2019. 3. The contractual undiscounted cash flows of accounts payable (including related parties), payables to contractors and equipment suppliers and other payables (including related parties) are due within one year and are equivalent to their carrying amounts. Except for the aforementioned, the table below summarizes the maturity profile of the Group’s non-derivative .

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 costs, contract assets, accounts and notes receivable, other receivables, refundable deposits, bank loans, contract liabilities, accounts payable, payables to contractors and equipment suppliers, 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 is as follows: December 31, 2018 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 - Foreign partnership interests — — 11,471 11,471 Financial assets at fair value through other comprehensive income - Foreign unlisted stocks — — 174,357 174,357 — — 185,828 185,828 December 31, 2019 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 - Foreign partnership interests — — 11,038 11,038 Financial assets at fair value through other comprehensive income - Foreign unlisted stocks — — 121,808 121,808 — — 132,846 132,846 ii) The methods and assumptions the Group used to measure fair value are as follows: 1. The fair value of the Group’s 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. 2. The Group’s financial assets at fair value through profit or loss is measured by using the discounted cash flow method, which derives present value estimates by discounting expected future operating effectiveness and free cash flows projections. 3. The Group’s financial assets at fair value through other comprehensive income is measured by the comparable company valuation (EV/EBITDA ratio and P/B ratio). 4. 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, 2018 and 2019: December 31, 2018 Debt Equity Total NT$000 NT$000 NT$000 January 1 — — — Effects on initial application of IFRS 9 11,433 89,335 100,768 Gains or losses recognized in profit or loss Recorded as non-operating 38 — 38 Gains or losses recognized in other comprehensive income Recorded as unrealized gains on valuation of financial assets at fair value through other comprehensive income — 85,022 85,022 December 31 11,471 174,357 185,828 December 31, 2019 Debt Equity Total NT$000 NT$000 NT$000 January 1 11,471 174,357 185,828 Gains or losses recognized in profit or loss Recorded as non-operating (433 ) — (433 ) Gains or losses recognized in other comprehensive income Recorded as unrealized losses on valuation of financial assets at fair value through other comprehensive income — (52,549 ) (52,549 ) December 31 11,038 121,808 132,846 (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, performing back-testing, 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, 2018 Valuation technique Significant unobservable Range (weighted average Relationship of inputs to fair value NT$000 Non-derivative Foreign partnership interests 11,471 Discounted cash flow Discount 0.35 % The lower the discount rate, the higher the fair value Non-derivative Foreign unlisted stocks 174,357 Comparable companies Price to book 1.19 The higher the multiple, the higher the fair value Enterprise 7.69 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 partnership interests 11,038 Discounted cash flow Discount 0.30 % The lower the discount rate, the higher the fair value Non-derivative Foreign unlisted stocks 121,808 Comparable companies Price to book 1.22 The higher the multiple, the higher the fair value Enterprise 10.51 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, 2018 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% — — 69 68 Enterprise value to EBITDA multiple ± 1% — — 1,563 1,512 Discount for lack of marketability ± 1% — — 2,093 2,050 — — 3,725 3,630 December 31, 2019 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% — — 53 53 Enterprise value to EBITDA multiple ± 1% — — 850 900 Discount for lack of marketability ± 1% — — 1,460 1,460 — — 2,363 2,413 Note: Based on the Group’s assessment, change in input would not have significant impact on profit or loss or other comprehensive income. |

Effects on initial application of IFRS 9 and information for the years ended December 31, 2016 and 2017 in conformity with IAS 39 | 39. Effects on initial application of IFRS 9 and information for the year ended December 31, 2017 in conformity with IAS 39 a) Summaries of adopting significant accounting policies for the year ended December 31, 2017: Investments and other financial assets Initial recognition and measurement The Group’s financial assets are classified, at initial recognition, into financial assets at FVTPL, loans and receivables and available-for-sale All regular way purchases or sales of financial assets are recognized on the settlement date, that is, the date that the Group completes the purchase or sell of the asset. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the time frame established by regulation or convention in the marketplace. Effective interest method The effective interest method is a method of calculating the amortized cost of loans and receivables and a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees on points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, where appropriate, a shorter period. Income is recognized on an effective interest basis for debt instruments. Subsequent measurement The subsequent measurement of financial assets depends on their classification as follows: Financial assets at fair value through profit or loss Financial assets at FVTPL include financial assets held for trading and those designated as at FVTPL upon initial recognition. A financial asset is classified as held for trading, mainly for cash management purpose as part of operating activities, if it has been acquired principally for the purpose of selling in the near future; or it is a part of an identified portfolio of financial instruments that the Group manages together and has a recent actual pattern of short-term profit-taking; or it is a derivative that is not designated and effective as a hedging instrument. A financial asset other than a financial asset held for trading may be designated as at FVTPL upon initial recognition if: • such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or • the financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on fair value basis, in accordance with the Group’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or • it forms part of a contract containing one or more embedded derivatives, and IAS 39 “Financial Instruments: Recognition and Measurement” permits the entire combined contract (asset or liability) to be designated as at FVTPL. Loans and receivables Loans and receivables are non-derivative Available-for-sale Available-for-sale non-derivative When the fair value of unlisted equity investments cannot be reliably measured because (a) the variability in the range of reasonable fair value estimates is significant for that investment or (b) the probabilities of the various estimates within the range cannot be reasonably assessed and used in estimating fair value, such investments are stated at cost less any impairment losses. The Group evaluates whether the ability and intention to sell its available-for-sale Impairment of financial assets The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired. An impairment exists if one or more events that occurred after the initial recognition of the asset have an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated. Evidence of impairment may include indications that a debtor or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization and observable data indicating that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults. Financial assets carried at amortized cost For financial assets carried at amortized cost, the Group first assesses whether impairment exists individually for financial assets that are individually significant, or collectively for financial assets that are not individually significant. If the Group determines that no objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, it includes the asset in a group of financial assets with similar credit risk characteristics and collectively assesses them for impairment. Assets that are individually assessed for impairment and for which an impairment loss is, or continues to be, recognized are not included in a collective assessment of impairment. The amount of any impairment loss identified is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not yet been incurred). The present value of the estimated future cash flows is discounted at the financial asset’s original effective interest rate (i.e., the effective interest rate computed at initial recognition). The carrying amount of the asset is reduced through the use of an allowance account and the loss is recognized in the consolidated statements of comprehensive income. Interest income continues to be accrued on the reduced carrying amount and is accrued using the rate of interest used to discount the future cash flows for the purpose of measuring the impairment loss. Loans and receivables together with any associated allowance are written off when there is no realistic prospect of future recovery and all collateral has been realized or has been transferred to the Group. If, in a subsequent period, the amount of the estimated impairment loss increases or decreases because of an event occurring after the impairment was recognized, the previously recognized impairment loss is increased or reduced by adjusting the allowance account. If a write-off is Available-for-sale financial assets The amount of the impairment loss is measured as the difference between the asset’s acquisition cost (less any principal repayment and amortization) and current fair value, less any impairment loss on that financial asset previously recognized in profit or loss, and is reclassified from “other comprehensive income” to “profit or loss”. If, in a subsequent period, the fair value of an investment in a debt instrument increases, and the increase can be related objectively to an event occurring after the impairment loss was recognized, then such impairment loss is reversed through profit or loss. Impairment loss of an investment in an equity instrument recognized in profit or loss shall not be reversed through profit or loss. Impairment loss is recognized and reversed by adjusting the carrying amount of the asset directly. b) The Group initially applied IFRS 9 on January 1, 2018, and recorded loss allowance based on expected credit loss. The impact was contract assets decreased by NT$115 thousand, accounts receivable decreased by NT$1,819 thousand, other receivables decreased by NT$5 thousand, other receivables – related parties decreased by NT$2 thousand, retained earnings decreased by NT$1,940 thousand and deferred tax assets increased by NT$1 thousand. c) The carrying amount of financial assets transferred from December 31, 2017 under IAS 39 to January 1, 2018 under IFRS 9 is reconciled as follows: Effects Note Measured Measured through Measured at fair value comprehensive income Other financial assets Measured amortized cost Total Retained earnings Other equity interest NT$000 NT$000 NT$000 NT$000 NT$000 NT$000 NT$000 NT$000 IAS 39 20,890 — — 70,241 — 91,131 — — Transferred into and measured at fair value through profit or loss (c) (10,940 ) 10,940 — — — — — — Transferred into and measured at fair value through other comprehensive income (b) (9,950 ) — 9,950 — — — — — Transfer into and measured at amortized cost (a) — — — (70,241 ) 70,241 — — — Fair value adjustment (b)(c) — 493 50,801 — — 51,294 493 79,385 Impairment loss adjustment (b) — — 28,584 — — 28,584 28,584 (28,584 ) Income tax adjustment (b) — — — — — — — (8,636 ) IFRS 9 — 11,433 89,335 — 70,241 171,009 29,077 42,165 (a) The Group’s restricted bank deposits that failed to meet the definition of cash and cash equivalents amounted to NT$70,241 thousand were classified as “Other financial assets” under IAS 39. Since the assets’ cash flows represent solely payments of principal and interest, the restricted bank deposits were reclassified as “Financial assets at amortized cost” amounted to NT$70,241 thousand on initial application of IFRS 9. (b) Given the Group’s available-for-sale (c) The Group’s available-for-sale d) The significant account as of December 31, 2017 is as follows: Available-for-sale December 31, NT$000 Unlisted equity investments, at cost 49,474 Less: Allowance for impairment losses (28,584 ) 20,890 Due to the operation loss and accumulated deficit of VIGOUR TECHNOLOGY Corporation (“VIGOUR”), the Company has recognized full impairment loss of its investments on VIGOUR amounted to NT$41,336 thousand in prior years. Based on the Company’s assessment, considering VIGOUR is currently in liquidation process and no residual assets are expected to be available for distributions, the carrying amount of investments and accumulated impairment losses were reclassified to “Other receivables” in the fourth quarter of 2017. As of December 31, 2017, no available-for-sale e) Credit risk information as of December 31, 2017 is as follows: (a) 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. The Group is exposed to credit risk from its operating activities (primarily accounts and other receivables) and from its financing activities (primarily deposits with banks and financial instruments). (b) Each business unit performs ongoing credit evaluation of the debtors’ financial condition according to the Group’s established policy, procedures and control relating to customer credit risk management. The Group maintains an account for allowance for doubtful receivables based upon the available facts and circumstances, historical collection and write-off (c) Credit risk from balances with banks and financial institutions is managed by the Group’s finance unit in accordance with the Group’s policy. Bank balances are held with financial institutions of good standing. The Group’s exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these instruments. (d) The aging of accounts receivable which are past due but not impaired is as follows: December 31, NT$000 £ 10,482 1 – 2 months 477 2 – 3 months 426 3 – 4 months 1,431 > 4 months 3,056 15,872 (e) The movements in allowance for impairment of accounts and other receivables during the year is as follows: Accounts Other NT$000 NT$000 January 1, 2017 87 — Reversal of allowance for impairment losses (87 ) — December 31, 2017 — — Receivables that were neither past due nor impaired relate to a large number of diversified customers for whom there was no recent history of default. Receivables that were past due but not impaired relate to a number of independent customers that have a good track record with the Group. Based on past experience, the management of the Company are of the opinion that no provision for impairment is necessary in respect of these balances as there has not been a significant change in credit quality and the balances are still considered fully recoverable. The individually impaired receivables related to customers that were in financial difficulties or other factors, e.g. the customers were in default or delinquency in interest or principal payments and only a portion of the receivables is expected to be recovered. The Group’s accounts receivable that were neither past due nor impaired were fully performed in line with the credit standards prescribed based on counterparties’ industrial characteristics, scale of business and profitability. (f) As of December 31, 2017, no accounts and notes and other receivables were pledged. |

Effects of initial application of IFRS 15 and information for the year ended December 31, 2017 in conformity with IAS 18 | 40. Effects of initial application of IFRS 15 and information for the year ended December 31, 2017 in conformity with IAS 18 a) The significant accounting policies applied on revenue recognition for the year ended December 31, 2017 is set out below: Revenue recognition Revenue is recognized to the extent that it is probable that the economic benefits arising in the course of business will flow to the Group and the revenue can be reliably measured, regardless of when the payment is being made. Revenue is measured at the fair value of the consideration received or receivable, taking into account contractually defined terms of payment and excluding taxes or duty. The Group engaged in the research, development, manufacturing and sale of high-integration and high-precision integrated circuits and related assembly and testing services. The criteria that the Group uses to determine when to recognize revenue are: (a) the Group has transferred to the buyer the significant risks and rewards of ownership of the goods; (b) the Group retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold; (c) the amount of revenue can be measured reliably; (d) it is probable that the economic benefits associated with the transaction will flow to the Group ; (e) the stage of completion of the transaction at the end of the reporting period can be measured reliably, and (f) the costs incurred for the transaction and the costs to complete the transaction can be measured reliably. The Group does not take ownership of: (1) bare semiconductor wafers received from customers that are assembled into finished semiconductors, and (2) assembled semiconductors received from the customers that it tests. The title and risk of loss remains with the customer for those bare semiconductors and/or assembled semiconductors. Accordingly, the customer-supplied semiconductor materials are not included in the consolidated financial statements. The Group does not provide warranties to customers except in cases of defects in the assembly services provided and deficiencies in testing services provided. An appropriate sales allowance is recognized in the period during which the sale is recognized, and is estimated based on historical experience. b) The revenue recognized by using above accounting policies for the year ended December 31, 2017 is provided in Note 4. c) The impact and description on consolidated statement of financial position and statement of comprehensive income if the Group continues adopting above accounting policies as of and for the year ended December 31, 2018 are as follows: December 31, 2018 Consolidated statement of financial position items Description Balance under IFRS 15 Balance under previous accounting policies Impact on accounting policy change NT$000 NT$000 NT$000 Contract assets (d)(f)(g) 299,835 — 299,835 Inventories (e) 1,778,835 2,016,106 (237,271 ) Deferred tax assets (h) 226,716 226,635 81 Contract liabilities (i) 1,432 — 1,432 Receipts in advance (i) 1,013 2,445 (1,432 ) Current provisions (j) 29,352 61,979 (32,627 ) Current refund liabilities (j) 32,627 — 32,627 Retained earnings 3,602,663 3,540,018 62,645 2018 Consolidated statement of comprehensive income items Description Balance under IFRS 15 Balance under previous accounting policies Impact on accounting policy change NT$000 NT$000 NT$000 Revenue (a)(d) 18,480,027 18,434,763 45,264 Cost of revenue (a)(e) (15,050,032 ) (15,021,266 ) (28,766 ) Operating expenses (f) (1,477,788 ) (1,477,653 ) (135 ) Other non-operating (expenses), net (g) 173,070 173,476 (406 ) Income tax expense (c)(h) (456,618 ) (465,392 ) 8,774 Profit for the year 1,325,824 1,301,093 24,731 Earnings per share (in dollars) Basic NT$ 1.65 NT$ 1.62 NT$ 0.03 Diluted NT$ 1.63 NT$ 1.60 NT$ 0.03 Explanation on the adjustments: Impact on January 1, 2018 (a) Revenue recognition of customized products The Group provides high-integration and high-precision integrated circuits and related assembly and testing services based on the specifications as required by the customers. The revenue is recognized when the significant risks and rewards are transferred to customers under previous accounting policies, and the timing of recognition usually occurred upon service completion. Under IFRS 15, considering that the Group provides assembly and testing service to create or enhance a highly customized product and the customer controls the asset as it is created or enhanced, the revenue will be recognized based on the progress towards completion. As a result, retained earnings increased by NT$46,607 thousand, inventories decreased by NT$208,505 thousand and contract assets increased by NT$255,112 thousand. (b) Presentation of refund liabilities By adopting IFRS 15, the Group’s provision for sales allowance amounted to NT$70,156 thousand is presented as current refund liabilities from January 1, 2018, which was previously presented as current provisions. (c) Recognition of deferred tax When initially adopting IFRS 15, the Group recognized adjustments in the statement of financial position which resulted to temporary differences. Accordingly, as of January 1, 2018, deferred tax assets decreased by NT$626 thousand, deferred tax liabilities increased by NT$8,067 thousand and retained earnings decreased by NT$8,693 thousand. Impact on December 31, 2018 (d) Contract assets and revenue recognition Under IFRS 15, the Group provides assembly and testing service to create or enhance a highly customized product and the customer controls the asset as it is created or enhanced, the revenue will be recognized based on the progress towards completion. As a result, contract assets and revenue increased by NT$300,376 thousand as of December 31, 2018. (e) Transfer inventory to cost of revenue Under IFRS 15, when revenue is recognized based on the progress towards completion, work in process and finished goods in ending inventories should be transferred to cost of revenue at the end of the reporting period. As a result, inventories decreased and cost of revenue increased by NT$237,271 thousand as of December 31, 2018. (f) Expected credit loss recognition Under IFRS 15, when contract assets and revenue are recognized based on the progress towards completion, loss allowance is recognized based on the expected credit loss model. As a result, expected credit loss increased and contract assets decreased by NT$135 thousand for the year ended December 31, 2018. (g) Foreign exchange Under IFRS 15, when contract assets and revenue are recognized based on the progress towards completion, foreign exchange loss is also recognized using the exchange rates prevailing at the statement of financial position date. As a result, foreign exchange loss increased and contract assets decreased by NT$406 thousand for the year ended December 31, 2018. (h) Recognition of deferred tax In summary, foreign exchange loss recognized would result to a temporary difference. Accordingly, deferred tax assets increased and income tax expense decreased by NT$81 thousand for the year ended December 31, 2018. (i) Presentation of contract liabilities By adopting IFRS 15, advance payments amounted to NT$1,432 thousand in certain assembly and testing service contracts were presented as contract liabilities as of December 31, 2018, which were previously presented as receipts in advance. (j) Presentation of refund liabilities By adopting IFRS 15, the Group’s provision for sales allowance amounted to NT$32,627 thousand was presented as current refund liabilities as of December 31, 2018, which was previously presented as current provisions. |

Text block [abstract] | |
Basis of preparation | a) Basis of preparation (a) These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”), International Accounting Standards (“IAS”), International Financial Reporting Interpretations Committee (“IFRIC”) interpretations and Standing Interpretations Committee (“SIC”) interpretations issued by the International Accounting Standards Board (“IASB”), (collectively, “IFRSs”). (b) 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. (c) These consolidated financial statements are presented in New Taiwan dollars (“NT$”), which is the Company’s functional currency. (d) The initial adoption of IFRS 9 “Financial Instruments” (“IFRS 9”) and IFRS 15 “Revenue from Contracts with Customers” (“IFRS 15”) is effective on January 1, 2018, the Group has elected to apply modified retrospective approach whereby the cumulative impact of the application was recognized as retained earnings or other equity interest as of January 1, 2018 and the financial statements for the year ended December 31, 2017 were not restated. The financial statements for the year ended December 31, 2017 were prepared in compliance with IAS 39 “Financial Instruments”, IAS 18 “Revenue” and relating interpretations. Please refer to Notes 39 and 40 for details of significant accounting policies. |
New and amended standards adopted by the group | b) New and amended standards adopted by the group New Standards, Interpretations and Amendments Effective date issued by IFRS 16, “Leases” January 1, 2019 (a) IFRS 16 “Leases” (“IFRS 16”), supersedes IAS 17 “Leases” (“IAS 17”) and the related interpretations issued by the Standing Interpretation Committee. The standard requires lessees to recognize a right-of-use low-value (b) The Group has elected to apply IFRS 16 by not restating the comparative information (referred herein as the “simplified retrospective approach”) when applying IFRSs effective in 2019. Accordingly, the Group increased right-of-use (c) The Group has adopted the following practical expedients permitted by the standard at the date of initial application of IFRS 16: i) Reassessment as to whether a contract is, or contains, a lease is not required, instead, the application of IFRS 16 depends on whether or not the contracts were previously identified as leases applying IAS 17 and IFRIC 4 “Determining whether an Arrangement contains a Lease”. ii) The use of a single discount rate to a portfolio of leases with reasonably similar characteristics. iii) The accounting for operating leases whose period will end before December 31, 2019 as short-term leases and accordingly, rent expense of NT$ 28,126 thousand was recognized for the year ended 2019. (d) The Group calculated the present value of lease liabilities by using the incremental borrowing interest rate, ranging from 1.7895% to 3.9474%. (e) The reconciliation between operating lease commitments for the remaining lease payments under IAS 17 and lease liabilities recognized as of January 1, 2019, measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate is as follows: NT$000 Operating lease commitments disclosed by applying IAS 17 as of December 31, 2018 320,214 Add: Lease payable recognized under finance lease by applying IAS 17 as of December 31, 2018 17,792 Less: Short-term leases (28,121 ) Add: Adjustments as a result of a different treatment of extension and termination options 874,298 Total lease contracts amount recognized as lease liabilities by applying IFRS 16 on January 1, 2019 1,184,183 Incremental borrowing interest rate at the date of initial application 1.7895%~3.9474% Lease liabilities recognized as of January 1, 2019 by applying IFRS 16 884,275 Other Amendments to IFRSs not listed above are not expected to have a material impact on the Group in the current or future reporting periods and on foreseeable future transactions. |
New and revised International Financial Reporting Standards not yet adopted | c) New and revised International Financial Reporting Standards not yet adopted None. |
Basis of consolidation | d) 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 businesses Location 2018 2019 The Company ChipMOS U.S.A., Inc. (“ChipMOS USA”) Research, development and marketing of semiconductors, circuits, and electronic related products San Jose, USA 100 100 The Company ChipMOS BVI Holding company British Virgin Islands 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 |
Foreign currency translation | e) 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 | f) 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 | g) 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 | h) 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 | (i) 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 | j) 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 bank 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 | k) 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 | l) 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 | m) 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 | n) 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 in associates | o) Investments in 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 | p) 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 |
Leases | q) Leases Effective from 2019 Leasing arrangements (lessee) – right-of-use (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 Prior to 2019 Leased assets / operating leases (lessee) (a) Based on the terms of a lease contract, a lease is classified as a finance lease if the Group assumes substantially all the risks and rewards incidental to ownership of the leased asset. i) A finance lease is recognized as an asset and a liability at the lease’s commencement at the lower of the fair value of the leased asset or the present value of the minimum lease payments. ii) The minimum lease payments are apportioned between the finance charges and the reduction of the outstanding liability. The finance charges are allocated to each period over the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability. iii) Property, plant and equipment held under finance leases are depreciated over their estimated useful lives. If there is no reasonable certainty that the Group will obtain ownership at the end of the lease, the asset shall be depreciated over the shorter of the lease term and its useful life. (b) Payments made under an operating lease (net of any incentives received from the lessor) are recognized in profit or loss on a straight-line basis over the lease term. |
Impairment of non-financial assets | r) 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 | s) 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 payable | t) Accounts payable Accounts payable are liabilities for purchases of raw materials, goods or services. The short-term accounts payable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial. |
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. |
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 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. |
Issued capital | y) Issued capital (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 believes that aforementioned methods are the most appropriate manner to measure the satisfaction of performance obligation to customers because the input costs incurred to assembly and testing volume completed in testing services are based on customer’s specification and 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. |
Operating segments | bb) 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 | cc) 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: (a) Critical judgments in applying the Group’s accounting policies Provisions for deficiency compensation The Group is primarily engaged in the research, development, manufacturing, sale, and assembly and testing of high-integration and high-precision integrated circuits. In any cases where deficiencies in the assembly and testing services arise, the Group has to clarify the reason for deficiencies and attribute of responsibilities. The Group follows the guidance of IAS 37 “Provisions, Contingent Liabilities and Contingent Assets” to determine warranty provisions. Since the timing and amount of these warranties are based on assumptions and estimates it requires management to make critical judgments. (b) Critical accounting estimates and assumptions Revenue recognition i) 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. ii) The Group estimates sales refund liabilities for sales allowance based on historical results and other known factors. Provisions for such liabilities are recorded as a deduction to revenues when the sales are recognized. The Group reassesses the reasonableness of estimates of discounts and returns periodically. |
