Material accounting policies | Note 4. Material accounting policies The material accounting policies applied in the preparation of these consolidated financial statements are set out as below. The accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements, except if mentioned otherwise. The accounting policies have been applied consistently by consolidated entities. (a) Basis of Consolidation The accompanying consolidated financial statements include the accounts and operations of Himax Technologies, Inc. and its majority owned subsidiaries and entities that it has a controlling financial interest. The Company ‘controls’ an entity when it is exposed to, 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. All significant intercompany balances and transactions have been eliminated in consolidation. ​ (b) List of Subsidiaries in the Consolidated Financial Statements Following is general information about Himax Technologies, Inc.’s subsidiaries:

Note (1): | On December 30, 2023, Himax Technologies, Inc. acquired the controlling interest in Viewsil and included it as the consolidated entity. Refer to Note 5 for further details. In addition, on November 22, 2024, Himax Technologies (Shenzhen) Co., Ltd. acquired the 51% of the outstanding voting shares of Viewsil, then the Company has 100% shareholdings in Viewsil.
Principal Activities The Company is a leading global fabless semiconductor solution provider dedicated to display imaging processing technologies. The Company’s display driver ICs and timing controllers have been adopted at scale across multiple industries worldwide including TVs, PC monitors, laptops, mobile phones, tablets, automotive, ePaper devices, industrial displays, among others. As the global market share leader in automotive display technology, the Company offers innovative and comprehensive automotive IC solutions, including traditional driver ICs, advanced in-cell Touch and Display Driver Integration (TDDI), local dimming timing controllers (Local Dimming TCON), Large Touch and Display Driver Integration (LTDI) for LCD displays and DDIC, TCON and on-cell touch controller for OLED displays. Besides, the Company designs and provides touch controllers, OLED ICs, LED drivers, EPD ICs, power management ICs, and CMOS image sensors for diverse display application coverage.

The Company’s industry-leading WiseEyeTM Ultralow Power AI Sensing technology is composed of Himax proprietary ultralow power AI processor, always-on CMOS image sensor, and CNN-based AI algorithm, and has been widely adopted in consumer electronics and AIoT related applications. The Company optics technologies, such as wafer level optics, LCoS micro-displays and 3D sensing solutions, are critical for facilitating emerging AR/VR/metaverse technologies. (c) Foreign Currency The reporting currency of the Company is the United States dollar (USD). The functional currency for the Company and its major operating subsidiaries is the USD. Accordingly, the assets and liabilities of subsidiaries whose functional currency is other than the USD are included in the consolidation by translating the assets and liabilities into the reporting currency (the USD) at the exchange rates applicable at the end of the reporting period. Equity accounts are translated at historical rates. The statements of profit or loss and cash flows are translated at the average exchange rates at the date of transaction. Translation gains or losses are accumulated as a separate component of equity in accumulated other comprehensive income. (d) Classification of Current and Noncurrent Assets and Liabilities Current assets are assets held for trading purposes and assets expected to be converted to cash, sold or consumed within one year from the end of the reporting period. Current liabilities are obligations incurred for trading purposes and obligations expected to be settled within one year from the end of the reporting period. Assets and liabilities that are not classified as current are noncurrent assets and liabilities, respectively. (e) Cash and Cash Equivalents Cash comprise cash balances and demand deposits. Cash equivalents comprise short-term highly liquid investments that are readily convertible into known amounts of cash and are subject to an insignificant risk of changes in their fair value. Deposits with an original maturity of three months or less at the time of purchase but not for investments and other purposes and are qualified with the aforementioned criteria are classified as cash equivalent. (f) Financial Instruments The Company shall recognize a financial asset or a financial liability in its statement of financial position when, and only when, the Company becomes party to the contractual provisions of the instrument. A regular way purchase or sale of financial assets shall be recognized and derecognized, as applicable, using trade date accounting.
| 1. | Financial Assets
| (i) | Classification of financial assets
The classification of financial assets depends on the nature and purpose of the financial assets and is determined at the time of initial recognition. Financial assets are classified into the following categories: measured at amortized cost, measured at fair value through other comprehensive income (FVTOCI) and measured at fair value through profit or loss (FVTPL). The classification of financial assets is generally based on the business model in which a financial asset is managed and its contractual cash flow characteristics. When, and only when, the Company changes its business model for managing financial assets it shall reclassify all affected financial assets.
| i. | Financial assets measured at amortized cost
A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at fair value through profit or loss:
| (i) | the asset held within a business model whose objective is to hold assets to collect contractual cash flows; and
| (ii) | the contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.
Financial assets measured at amortized cost are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
| ii. | Financial assets measured at fair value through other comprehensive income (FVTOCI)
On initial recognition of an equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in the investment’s fair value in OCI. This election is made on an investment-by-investment basis. Equity investments at FVTOCI are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI. When an investment is derecognized, the cumulative gain or loss in equity will not be reclassified to profit or loss, instead, is reclassified to retained earnings.
| iii. | Financial assets measured at fair value through profit or loss (FVTPL)
All financial assets not classified as measured at amortized cost or at fair value through other comprehensive income as described above are measured at fair value through profit or loss. Such financial assets are initially recognized at fair value, and attributable transaction costs are recognized in profit or loss as incurred. Subsequent to initial recognition, they are measured at fair value and changes therein are recognized in profit or loss.
| (ii) | Impairment of financial assets
The Company recognizes loss allowances for expected credit loss on financial assets measured at amortized cost (including accounts receivable). The loss allowance for accounts receivable is measured at an amount equal to lifetime expected credit losses. For financial assets at amortized cost and contract assets, when the credit risk on the financial instrument has not increased significantly since initial recognition, a loss allowance is recognized at an amount equal to expected credit loss resulting from possible default events of a financial instrument within 12 months after the reporting date. If, on the other hand, there has been a significant increase in credit risk since initial recognition, a loss allowance is recognized at an amount equal to expected credit loss resulting from all possible default events over the expected life of a financial instrument. When determining whether the credit risk of a financial instrument has increased significantly since initial recognition, the Company considers reasonable and supportable information that is relevant. This includes both qualitative and quantitative information and analysis, based on the Company’s historical experience and credit assessment as well as forward-looking information. The Company recognizes an impairment gain or loss in profit or loss for all financial instruments with a corresponding adjustment to their carrying amount through a loss allowance account.
| (iii) | Derecognition of financial assets
The Company derecognizes a financial asset only when the contractual rights to the cash flows from the financial asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the financial asset to another entity. On derecognition of a financial asset at amortized cost in its entirety, the difference between the asset’s carrying amount and the sum of the consideration received and receivable is recognized in profit or loss. However, on derecognition of an investment in an equity instrument at FVTOCI, the cumulative gain or loss that had been recognized in other comprehensive income is transferred directly to retained earnings, without recycling through profit or loss.
| 2. | Financial Liabilities
| (i) | Classification of financial liability
The Company classify all financial liabilities as measured at amortized cost, except for financial liabilities measured at fair value through profit or loss. Such liabilities, including derivatives that are liabilities, shall be subsequently measured at fair value.
| (ii) | Derecognition of financial liability
The Company removes a financial liability from its statement of financial position when, and only when, it is extinguished-when the obligation specified in the contract is discharged or cancelled or expires. On derecognition of a financial liability at amortized cost in its entirety, the difference between the carrying amount of a financial liability extinguished or transferred to another party and the consideration paid, including any non-cash assets transferred or liabilities assumed, shall be recognized in profit or loss. (g) Inventories Inventories primarily consist of raw materials, work-in-process and finished goods awaiting final assembly and test and are stated at the lower of cost and net realizable value. Cost is determined using the weighted-average method. For work-in-process and manufactured inventories, cost consists of the cost of raw materials (primarily fabricated wafer and processed tape), direct labor and an appropriate proportion of production overheads. Net realizable value for raw materials is based on replacement cost. Net realizable value for finished goods and work in process is calculated based on the estimated selling price less all estimated costs of completion and necessary selling costs. (h) Equity Method Investments Equity investments in entities where the Company has the ability to exercise significant influence over the operating and financial policy decisions of the investee but does not have a controlling financial interest in the investee, are accounted for using the equity method. The Company’s share of the net income or net loss of an investee is recognized in earnings from the date the significant influence commences until the date that significant influence ceases. The difference between the cost of an investment and the amount of underlying equity in net assets of an investee at investment date is allocated to related assets which are amortized over their useful lives. Any unallocated difference is treated as investor-level goodwill and is not amortized. The Company discontinues the use of the equity method from the date when the Company ceases to have significant influence over an associate, and then measures the retained interests at fair value at that date. The difference between the carrying amount of the investment at the date the equity method was discontinued and the fair value of the retained interests along with any proceeds from disposing of a part of the interest in the associate is recognized in profit or loss. When the Company discontinues the use of the equity method, the Company shall account for all amounts previously recognized in other comprehensive income in relation to that investment on the same basis as would have been required if the investee had directly disposed of the related assets or liabilities. At the end of each reporting period, if there is any indication of impairment, the entire carrying amount of the investment including goodwill is tested for impairment as a single asset, by comparing its recoverable amount with its carrying amount. An impairment loss recognized forms part of the carrying amount of the investment in associates. Accordingly, any reversal of that impairment loss is recognized to the extent that the recoverable amount of the investment subsequently increases. (i) Property, Plant and Equipment Property, plant and equipment consists primarily of land, building and machinery and equipment used in the design and development of products, and is stated at cost less accumulated depreciation and any accumulated impairment loss. Depreciation on building and machinery and equipment commences when the asset is ready for its intended use. Except for the following paragraph, depreciation is primarily calculated on the straight-line method over the estimated useful lives of related assets which range as follows: building 25 years, building improvements 4 to 16 years, machinery 4 to 10 years, research and development equipment 2 to 6 years, office furniture and equipment 3 to 8 years, others 2 to 10 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the estimated useful life of the asset. Embedded software is amortized on a straight-line basis over the estimated useful lives ranging from 2 to 10 years. Land is not depreciated. If significant parts of an item of property, plant and equipment have different useful lives, then they are accounted for as separate items (major components) of property, plant and equipment. Depreciation methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate. Property, plant and equipment that are highly probable to be recovered primarily through sale rather than through continuing use, are reclassified as held for sale. Immediately before classification as held for sale, the assets are measured at the lower of their carrying amount and fair value less costs to sell. Impairment losses on assets initially classified as held for sale and any subsequent gains or losses on remeasurement are recognized in profit or loss. Gains are not recognized in excess of the cumulative impairment loss that has been recognized. Once classified as held for sale, the property, plant and equipment are no longer depreciated. (j) Leases
| a. | Identifying a lease
A contract is, or contains, a lease when all the following conditions are satisfied:
| (i) | the contract involves the use of an identified asset, and the supplier does not have a substantive right to substitute the asset; and
| (ii) | the Company has the right to obtain substantially all of the economic benefits from use of the identified asset throughout the period of use; and
(iii) the Company has the right to direct the use of the identified asset throughout the period of use.
| b. | As a lessee
Payments for leases of low-value assets and short-term leases are recognized as expenses on a straight-line basis during the lease term for which the recognition exemption is applied. Except for leases described above, a right-of-use asset and a lease liability shall be recognized for all other leases at the lease commencement date. The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The lease liability is initially measured at the present value of the lease payments, discounted using the lessee’s incremental borrowing rate. The Company determines its incremental borrowing rate by obtaining interest rates from various external financing sources. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability, adjusted for any lease payments made at or before the commencement date, less any lease incentives received, plus any initial direct costs incurred and an estimate of costs to be incurred in restoring the underlying asset. The right-of-use asset is subsequently depreciated using the straight-line method over the shorter of the useful life of the right-of-use asset or the lease term. The lease liability is subsequently measured at amortized cost using the effective interest method. It is remeasured (i) if there is a change in the lease term; (ii) if there is a change in future lease payments arising from a change in an index or a rate; (iii) if there is a change in the amounts expected to be payable under a residual value guarantee; or (iv) if the Company changes its assessment of whether it will exercise a purchase, extension or termination option. When the lease liability is remeasured in the circumstances aforementioned, a corresponding adjustment is made to the carrying amount of the right-of-use asset. However, if the carrying amount of the right-of-use asset is reduced to zero, any remaining amount of the remeasurement is recognized in profit or loss. Lease payments included in the measurement of the lease liability comprise the following:
| (i) | fixed payments, including in-substance fixed payments.
| (ii) | the exercise price under a purchase option that the Company is reasonably certain to exercise and lease payments in an optional renewal period if the Company is reasonably certain to exercise an extension option.
Moreover, the lease liability is remeasured when lease modifications occur that decrease the scope of the lease. The Company accounts for the remeasurement of the lease liability by decreasing the carrying amount of the right-of-use asset to reflect the partial or full termination of the lease and recognizes in profit or loss any gain or loss relating to the partial or full termination of the lease.
| c. | As a lessor
Lease income from an operating lease is recognized in profit or loss on a straight-line basis over the lease term. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the asset leased. (k) Goodwill Goodwill is recognized when the purchase price exceeds the fair value of identifiable net assets acquired in a business combination. Goodwill is measured at cost less accumulated impairment losses, if any. Goodwill from acquisition of Himax Semiconductor, Inc. (formerly Wisepal Technologies, Inc., merged into Himax Technologies Limited on July 2, 2018) in 2007 amounting $26,846 thousand has been assigned to Driver IC cash generating unit (“CGU”) and goodwill from acquisition of Himax Display (USA) Inc. in 2012 amounting $1,292 thousand has been assigned to WLO CGU because these CGUs are expected to benefit from the synergies of the business combinations. Goodwill is not amortized and instead is reviewed for impairment at least annually, or more frequently when there is an indication that the CGU may be impaired. For the purpose of impairment testing, goodwill is allocated to each of the Company’s CGU or groups of CGU that are expected to benefit from the synergies of the combination. If the recoverable amount of a cash-generating unit is less than its carrying amount, the difference is allocated first to reduce the carrying amount of any goodwill allocated to such CGU and then to the other assets of the CGU pro rata based on the carrying amount of each asset in the CGU. Any impairment loss for goodwill is recognized directly in profit or loss. An impairment loss recognized for goodwill is not reversed in subsequent periods. The recoverable amount is the higher of fair value less costs of disposal and value in use. In assessing value in use which was calculated based on the cash flow forecast from the financial budgets covering the future five-year period with the terminal growth rate. The annual discount rate was 9.95% and 9.04% in its test of Goodwill impairment for Driver IC CGU as of December 31, 2023 and 2024, respectively, based on industry weighted average cost of capital. The annual discount rate for WLO CGU was 13.96% and 13.78% as of December 31, 2023 and 2024, respectively. The terminal growth rate, based on following 5 years average Taiwan economic growth rate published by International Monetary Fund, was 2.6% and 2.48% used in the test for both CGUs as of December 31, 2023 and 2024, respectively. The key assumptions abovementioned represents the management’s forecast of the future for the related industry by considering the history information from internal and external sources. For the years ended December 31, 2022, 2023 and 2024, the Company did not recognize any impairment loss on goodwill. (l) Other Intangible Assets Acquired intangible assets include patents, intellectual property and developed technology acquired in a business combination. These intangible assets are amortized on a straight-line basis over the following estimated useful lives: software 2-10 years, patents 12-15 years, intellectual property 10 years and technology 7 years. Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate. (m) Impairment of Non-Financial Assets The Company’s long-term non-financial assets, which consist of property, plant and equipment and intangible assets, are reviewed at the reporting date to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. The recoverable amount of an asset or cash-generating unit is the greater of its value in use and its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Considering the terminal growth rate if non-financial assets with an indefinite useful life are allocated to the CGU in comparison with its carrying amount. For the purpose of impairment testing, assets that cannot be tested individually are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or groups of assets (the “cash-generating unit, or CGU”). An impairment loss is recognized if the carrying amount of an asset or its CGU exceeds its estimated recoverable amount. Impairment losses are recognized in profit or loss. When an impairment loss subsequently reverses, the carrying amount of the asset or a CGU is increased to the revised estimate of its recoverable amount, but the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset or CGU in prior years. A reversal of an impairment loss is recognized immediately in profit or loss. (n) Revenue Recognition IFRS 15 establishes principles for recognizing revenue that apply to all contracts with customers, using a five-step model framework to determine the method, timing and amount of revenue recognized. The Company generates revenue primarily from sale of goods or services. Revenue from contracts with customers is disaggregated by primarily geographical market and major products. Under IFRS 15, the Company identifies the contract with the customers and recognizes revenue when performance obligations are satisfied. Revenue is measured based on the consideration that the Company expects to be entitled in the transfer of goods or services to a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Customers obtain control of the product when the goods are delivered and accepted by customers. Invoices are generated at that point in time. The Company’s revenue recognition from product sales is measured at the amount that is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Revenue is reduced for estimated rebates and other similar allowances. Trade receivable is recognized when the Company is entitled for unconditional right to receive payment upon delivery of goods to customers. The consideration received in advance from the customer but without delivery of goods is recognized as a contract liability, for which revenue is recognized when the control over the goods is transferred to the customer. The Company expects that the length of time when the Company transfers the goods or services to the customer and when the customer pays for those goods or services will be less than one year. Therefore, the amount of consideration is not adjusted for the time value of money. (o) Employee Benefits
| 1. | Short-term employee benefits
Short-term employee benefits are expensed unless another policy allows or requires it to be capitalized. Liabilities recognized in respect of short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in exchange for service rendered by employees.
| 2. | Share-based payment arrangements
The cost of employee services received in exchange for share-based compensation is measured based on the grant-date fair value of the share-based instruments issued. The cost of employee services is equal to the grant-date fair value of shares issued to employees and is recognized in earnings with a corresponding increase in equity over the service period by graded vesting. Compensation cost also considers the number of awards management believes will eventually vest. As a result, compensation cost is reduced by the estimated forfeitures. The estimate is adjusted each period to reflect the current estimate of forfeitures, and finally, the actual number of awards that vest.
| 3. | Defined contribution plans
Obligations for contributions to defined contribution pension plans are recognized as an employee benefit expense in profit or loss in the periods during which services are rendered by employees.
| 4. | Defined benefit plans
The Company’s net obligation in respect of defined benefit pension plans is calculated separately for each benefit plan by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets. For defined benefit retirement benefit plans, the cost of providing benefit is recognized based on actuarial calculations. Defined benefit costs (including service cost, net interest and remeasurement) under the defined benefit retirement benefit plans are determined using the Projected Unit Credit Method. Service cost (including current service cost), and net interest on the net defined benefit liability (asset) are recognized as employee benefits expense in profit or loss in the period they occur. Remeasurement, comprising actuarial gains and losses and the return on plan assets (excluding interest), is recognized in other comprehensive income in the period in which they occur. Remeasurement recognized in other comprehensive income is reflected immediately in retained earnings and will not be reclassified to profit or loss. (p) Income Taxes Income tax expense comprises current and deferred taxes. It is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income. The Company has adopted International Tax Reform – Pillar Two Model Rules (Amendments to IAS 12) upon their release on May 23, 2023. The amendments provide a temporary mandatory exception from deferred tax accounting for the top-up tax, which is effective immediately, and require new disclosures about the Pillar Two exposure. The mandatory exception applies retrospectively. However, because no new legislation to implement the top-up tax was enacted or substantially enacted on December 31, 2022 in any jurisdiction in which the Company operates and no related deferred tax was recognized at that date, the retrospective application has no impact on the Company’s consolidated financial statements. The Company has applied a temporary mandatory relief from deferred tax accounting for the impacts of the top-up tax and accounts for it as a current tax when it is incurred. South Korea and Japan are the only two countries which represent jurisdictions where the Company maintains subsidiaries’ operations and have already enacted tax legislation on December 31, 2023. The Company has evaluated the current tax impact to be immaterial for the year ended December 31, 2023 and 2024, respectively.
| 1. | Current tax
Current taxes comprise the expected tax payable or receivable on the taxable income or losses for the year and any adjustments to tax payable or receivable in respect of previous years. It is measured using tax rates enacted or substantively enacted tax rate at the reporting date.
| 2. | Deferred tax
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in the financial statements and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized; such reductions are reversed when the probability of future taxable profits improves. (q) Business Combinations Acquisitions of businesses are accounted for using the acquisition method. Acquisition-related costs are generally recognized in profit or loss as incurred. Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree, and the fair value of the acquirer’s previously held equity interest in the acquiree over the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. Non-controlling interests are initially measured at the non-controlling interests’ proportionate share of the fair value of the acquiree’s identifiable net assets. Any contingent consideration payable is measured at fair value at the acquisition date. If the contingent consideration is classified as equity, then it is not remeasured and settlement is accounted for within equity. Otherwise, subsequent changes in the fair value of contingent consideration are recognized in profit or loss. When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree is remeasured to fair value at the acquisition date, and the resulting gain or loss is recognized in profit or loss. (r) Earnings Per Ordinary Share Basic earnings per ordinary share is computed using profit or loss attributable to the shareholders and weighted average number of ordinary shares outstanding during the period. Diluted earnings per ordinary share is computed using the weighted average number of ordinary and diluted ordinary equivalent shares outstanding during the period. Ordinary equivalent shares are ordinary shares that are contingently issuable upon the vesting of unvested restricted share units (RSUs) granted to employees. Basic and diluted earnings per ordinary share have been calculated as follows: ​

​ Note (1): As the Company’s ordinary shares have been quoted on the NASDAQ Global Select Market under the symbol “HIMX” in the form of ADSs and two ordinary shares represent one ADS with effect from August 10, 2009. The number of ADS equivalent outstanding is determined by dividing the number of ordinary shares by two. Therefore, the weighted average number of ADS equivalent outstanding used in basic earnings per ADS for 2022, 2023 and 2024 is 174,724 thousand, 174,495 thousand and 174,796 thousand, respectively. Additionally, the weighted average number of ADS equivalent outstanding used in diluted earnings per ADS for 2022, 2023 and 2024 is 174,817 thousand, 174,783 thousand and 175,014 thousand, respectively. The earnings per ADS is presented solely for the convenience of the reader and does not represent a measure under IFRS. (s) Segment Reporting An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses. All operating segments’ operating results are reviewed regularly by the Company’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. The Company’s CODM has been identified as the Chief Executive Officer, who regularly reviews operating results to make decisions about allocating resources and assessing performance for the Company. Management has determined that the Company has two operating segments: Driver IC and Non-driver products. The CODM assesses the performance of the operating segments based on segment sales and segment profit and loss. There are no intersegment sales in the segment revenues reported to the CODM. Segment profit and loss is determined on a basis that is consistent with how the Company reports operating income (loss) in its consolidated statements of operations. Segment profit (loss) excludes income taxes and items in non-operating income (loss). The Company does not report segment asset information to the Company’s CODM. Consequently, no asset information by segment is presented. (t) Noncontrolling Interests Noncontrolling interests are classified in the consolidated statements of profit or loss as part of profit (loss) for the period and the accumulated amount of noncontrolling interests as part of equity in the consolidated statements of financial position. If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interests are re-measured with the gain or loss reported in net earnings. (u) Use of Judgments and Estimates The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Information about critical judgments, estimates and assumptions in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes:
| 1. | Valuation of inventory
Inventories are stated at the lower of cost or net realizable value, and the Company uses judgment and estimate to determine the net realizable value of inventory at the end of each reporting period. Due to the rapid technological changes, the Company estimates the net realizable value of inventory for obsolescence and unmarketable items at the end of reporting period and then writes down the cost of inventories to net realizable value. The net realizable value of the inventory is mainly determined based on assumptions of future demand within a specific time horizon.
| 2. | Impairment of non-financial assets other than goodwill
In the process of evaluating the potential impairment of non-financial assets other than goodwill, the Company is required to make subjective judgments in determining the independent cash flows, useful lives, expected future revenue and expenses related to the specific asset groups. Any changes in these estimates based on changed economic conditions or business strategies could result in significant impairment charges or reversal in future years.
| 3. | Recognition of deferred tax assets
Deferred tax assets are recognized to the extent that it is probable that future taxable profits will be available against which those deferred tax assets can be utilized. Assessment of the realization of the deferred tax assets requires the Company’s subjective judgment and estimate, including the future revenue growth and profitability, the sources of taxable income, the amount of tax credits that can be utilized and feasible tax planning strategies. Changes in the economic environment, the industry trends and relevant laws and regulations may result in adjustments to the deferred tax assets.
| 4. | Impairment of goodwill
The assessment of impairment of goodwill requires the Company to make subjective judgment to determine the identified CGU, allocate the goodwill to relevant CGU and estimate the recoverable amount of relevant CGU. In the process of estimating the recoverable amount of relevant CGU, the Company is required to make subjective judgments in determining the discounted rate, the terminal growth rate, the independent cash flows, useful lives, expected future revenue and expenses related to the CGU.
