Basis of preparation of the financial statements	2. Basis of preparation of the financial statements (1) Applicable financial reporting framework These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The Group has prepared these consolidated financial statements in accordance with IFRS for the purpose of filing with the Securities and Exchange Commission of the United States of America in connection with the above mentioned Business Integration. (2) Basis of measurement The consolidated financial statements have been prepared on the historical cost basis except for the application of fair value measurements required or allowed by relevant accounting standards. Fair value measurement is explained below. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date regardless of whether that price is directly observable or estimated using another valuation technique. In estimating the fair value of an asset or a liability, the Group takes into account the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date. For financial reporting purposes, fair value measurements are categorized into Level 1, 2 or 3 based on the degree to which the inputs to the fair value measurements are observable and the significance of the inputs to the fair value measurement in its entirety, which are described as follows: • Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the entity can access at the measurement date; • Level 2 inputs are inputs other than quoted prices included within Level 1, that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices); • Level 3 inputs are unobservable inputs for the asset or liability. (3) Functional currency and presentation currency The consolidated financial statements are presented in Japanese yen, which is the functional currency of the Company and the presentation currency of the Group. All amounts have been rounded to the nearest million yen, unless otherwise indicated. (4) Significant accounting judgments, estimates and assumptions In preparing these consolidated financial statements under IFRS, management has made certain judgments, estimates and assumptions that affect the application of the Group’s 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 and are based on historical experience and other factors, including expectations of future events that are considered reasonable under the circumstances. Although the estimates were made based on best information available at the date of authorization for issuance of these consolidated financial statements, any changes to estimates that may occur in the future would be reflected prospectively from that time, and the effect of the change would be recognized in the consolidated statements of profit or loss and comprehensive income for the period in which the estimates are revised and in any future periods. Information about judgements, estimates and assumptions that have significant effects on the amounts recognized in the consolidated financial statements is as follows: (a) Scope of consolidation The Company’s most significant consolidated subsidiaries are Alpine and Alps Logistics Co., Ltd. (“Alps Logistics”), each of which originates from the Group’s business operations and forms the core segment companies of the Group. The Company holds less than half of the voting rights in Alpine until December 31, 2018 and Alps Logistics as of March 31, 2019, but has other power features. Analysis and judgment are required to assess whether the Company possesses power over Alpine and Alps Logistics through contractual and other rights, including consideration of indicators that give it the practical ability to unilaterally direct the relevant activities of Alpine and Alps Logistics. Based on comprehensive assessments, the Company concludes that it possesses the power, and ultimately controls Alpine and Alps Logistics. Different assessments may lead to significantly different financial results if Alpine and Alps Logistics were not to be consolidated, but accounted for under the equity method. See Note 3(1)(a) “Subsidiaries” and Note 30 “Principal subsidiaries” for more detail. (b) Useful lives of property, plant and equipment, and intangible assets Property, plant and equipment, except for land and construction in progress, are depreciated over the estimated useful lives that reflect the period in which the asset’s future economic benefits are expected to be consumed. Depreciation charges for the period may increase and the estimated useful lives may become shorter if any property, plant and equipment become obsolete or its original intended use is changed. For more information in relation to useful lives, see Note 3 (6) “Property, plant and equipment” and Note 3 (7) “Intangible assets.” (c) Impairment of non-financial The Company assesses at the end of each reporting period whether there is an indication that an asset may be impaired. If any such indication exists, the Company recognizes impairment losses when its carrying amount exceeds its recoverable amount. The recoverable amount of an asset or cash-generating unit (“CGU”) is the higher of fair value less costs of disposal and value in use. Value in use calculated and used in impairment tests is based on assumptions such as future cash flows, discount rates and long-term growth rates. These assumptions are based on the best estimates and judgments made by management. However, these assumptions may be affected by changes in future economic conditions, which may have a material impact on the consolidated financial statements in future periods. Fair value less costs of disposal is the price that would be received to sell the asset in an orderly transaction between market participants. The recoverable amount of CGU is further explained in Note 3 (9) “Impairment of property, plant and equipment, and intangible assets.” For more information in relation to impairment, see Note 8 (2) “Impairment losses.” (d) Recoverability of deferred tax assets In recognizing deferred tax assets, the Group estimates the timing and amount of future taxable income based on the Company’s business plans. Such estimates may be affected by future results of operations of the Company. For more descriptions of accounting policies and other information in relation to deferred tax assets, see Note 3 (15) “Income taxes” and Note 27 “Income taxes.” (e) Measurement of defined benefit obligations The Group has retirement benefits plans including defined benefit plans. The present value of defined benefit obligations of each of these plans and the service costs are calculated based on actuarial assumptions, which require estimates and judgments on variables such as discount rates and mortality rates. The Group obtains advice from external pension actuaries with respect to the appropriateness of these actuarial assumptions including these variables, and determines the actuarial assumptions based on the best estimates and judgments made by management. However, it is possible that these assumptions may be affected by changes in future economic conditions, or by the enactment or the amendment of related laws, which may have a material impact on the consolidated financial statements in future periods. The actuarial assumptions for measurement of defined benefit obligations are more fully described in Note 17 “Employee benefits.” (f) Measurement of financial assets without quoted prices in active markets The Group has used valuation techniques that incorporate unobservable inputs in the market when assessing the fair value of unlisted shares. Unobservable inputs may be affected by changes in uncertain future economic conditions, which may bring about changes in fair value of the shares, and result in a material impact on the consolidated financial statements in future periods. Valuation of financial assets is more fully described in Note 29 (7) “Fair value hierarchy of financial instruments.” (5) Accounting standards issued but not yet adopted At the date of authorization for issue of these consolidated financial statements, the following standard was issued by the IASB but not yet adopted by the Group: IFRS 16, “Leases,” was issued in January 2016 and specifies how an entity will recognize, measure, present and disclose leases. The standard provides a single lessee accounting model, requiring lessees to recognize assets and liabilities for most leases. IFRS 16 applies to annual reporting periods beginning on or after January 1, 2019. Accordingly, the Group will be required to adopt the new standard effective April 1, 2019. The Group will elect to use the modified retrospective approach with the cumulative effect on initially applying the new standard being recognized in the opening balance of the year of initial application. Based on current information, the main impact of transitioning to the new standard would result from the capitalization of warehouse and office leases that are currently classified as operating leases under IAS17. Upon adoption of this new standard on April 1, 2019, the Group anticipates recognizing right-of-use

Text block [abstract]
Significant accounting policies	3. Significant accounting policies Significant accounting policies and measurement basis used by the Group in preparing these consolidated financial statements are as follows. Except for (18) Revenue recognition (1) Basis of consolidation (a) Subsidiaries The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Group. Control is achieved when the Group has power over the investee, is exposed, or has rights, to variable returns from its involvement with the investee, and has the ability to use its power to affect its returns. The Group reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. The financial statements of the subsidiaries are consolidated into the consolidated financial statements of the Group from the date when the Group obtains control over a subsidiary until the date the Group loses control of the subsidiary. Additionally, the financial statements of subsidiaries are adjusted to conform to the accounting policies adopted by the Group, as necessary. The Group treats transactions with non-controlling non-controlling non-controlling Intercompany transactions, balances and unrealized gains on transactions between group companies are eliminated upon consolidation. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. When the Group ceases to have control over a subsidiary, any retained interest in the entity is remeasured to its fair value on the date when control is lost, with the change in the carrying amount recognized in profit or loss in its entirety. (b) Associates and joint ventures Associates are entities over which the Group has significant influence, but not control or joint control, over management decision-making in relation to their financial and operating policies. Significant influence is the power to participate in the financial and operating policy decisions of the entity. Joint control is a contractual arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. Joint arrangements are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each party. Joint ventures are joint arrangements whereby the parties who have joint control of the arrangement have the rights to the net assets of the arrangement. Investments in interests in associates and joint ventures are accounted for using the equity method. Under the equity method, investments in interests are initially recognized at cost, and adjusted for changes in the net assets of associates and joint ventures that arise after the date of the acquisition. When the Group’s interest in an associate or a joint venture is reduced, but the investment continues to be classified as an associate or a joint venture respectively, the Group reclassifies to profit or loss the proportion of the related gain or loss that had previously been recognized in other comprehensive income (“OCI”) corresponding to that reduction in ownership interest. However, where the investment ceases to be classified as an associate or joint venture but is classified as a financial asset, the Group measures the retained interest at fair value in accordance with IFRS 9, and recognizes in profit or loss any difference between such fair value and the carrying amount at the date the equity method was discontinued. The Group’s share of operating results of associates and joint ventures is adjusted to conform to the Group’s accounting policy and recognized as “Share of profit or loss of associates and joint ventures accounted for using the equity method” in the consolidated statements of profit or loss. Unrealized gains or losses on transactions are eliminated to the extent of the Group’s interest in the investee. Impairment in respect of an equity-method investee is measured by comparing the recoverable amount of the investment with its carrying amount. An impairment is recognized in profit or loss, and is reversed if there has been a favorable change in the estimates used to determine the recoverable amount. (2) Foreign currency transactions (a) Foreign currency transactions Foreign currency transactions are converted into the functional currency of each company using foreign currency exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date. Non-monetary Non-monetary (b) Translation of foreign operations The assets and liabilities of foreign operations, which use a functional currency other than Japanese yen are translated into Japanese yen at exchange rates at the reporting date. Income and expenses of foreign operations are translated into Japanese yen at exchange rates at the dates of the transactions, which are approximated using average exchange rates, unless the exchange rates fluctuate significantly. Foreign currency differences are recognized in OCI and accumulated in the foreign currency translation reserve in other components of equity, except to the extent that the translation difference is allocated to NCI. When a foreign operation is disposed of in its entirety or partially such that control or significant influence is lost, the cumulative amount in the foreign currency translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal. If the Group disposes of part of its interest in a subsidiary but retains control, the relevant proportion of the cumulative amount is reattributed to NCI. When the Group disposes of only part of an associate while retaining significant influence, the relevant proportion of the cumulative amount is reclassified to profit or loss. (3) Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker is responsible for allocating resources and assessing performance of the operating segments and is considered to be the board of directors of the Company. (4) Cash and cash equivalents Cash and cash equivalents include cash on hand, deposits held at call with financial institutions, other short-term, highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value. (5) Inventories Inventories are valued at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business less the estimated selling costs. The costs of inventories include direct materials, direct labor and an appropriate proportion of variable and fixed overhead expenditure, which are allocated on the basis of normal operating capacity. Costs are assigned to individual items of inventory on the basis of weighted average costs. Costs of purchased inventory are determined after deducting rebates and discounts. (6) Property, plant and equipment Property, plant and equipment are measured initially at cost and subsequently carried at the amount net of any accumulated depreciation and any accumulated impairment losses. Costs incurred to enlarge, upgrade or improve the items that increase productivity, capacity or efficiency, or extend the useful lives of the assets are capitalized as an increase in the cost of the related asset, while repairs and maintenance expenses are charged to expense as incurred. The depreciable amount is the cost of the asset less the estimated residual values. The Group depreciates its property, plant and equipment primarily using the straight-line method over the useful lives, as follows: Years of useful lives Buildings and structures 2 – 50 Machinery, equipment and vehicles 1 – 17 Tools, furniture and fixtures 1 – 20 The depreciation methods, useful lives and residual values are reviewed at the end of each reporting period, and any necessary changes are applied prospectively as a change in accounting estimate. Gains or losses arising from the sales or disposals of an asset are determined as the difference between the carrying amount of the asset and its sales proceeds and recognized in “Other operating income” or “Other operating expenses” in the consolidated statements of profit or loss. (7) Intangible assets Intangible assets are measured initially at cost of acquisition or development. After initial recognition, intangible assets are carried at cost less accumulated amortizations and any accumulated impairment losses. Intangible assets acquired separately are measured at cost at initial recognition. Intangible assets are amortized using the straight-line method over their estimated useful lives. Useful lives of major categories of intangible assets are as follows: Years of useful lives Software 2 – 10 Development costs 2 – 5 The amortization methods, useful lives and residual values are reviewed at the end of each reporting period, and if there are any changes necessary, those changes are applied prospectively as a change in accounting estimate. Expenditures on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset. (8) Leases The determination of whether an arrangement is a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains a lease if fulfilment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement. Lessee The Group leases property, plant and equipment and intangible assets as a lessee. The determination of whether an agreement contains a lease is based on the examination of the economic nature of the transactions regardless of the form of the lease. Among the lease transactions, those that substantially transfer all the risks and rewards of ownership to the Group are classified as finance leases, and leases other than finance leases are classified as operating leases. For finance leases, leased assets (presented in the respective accounts of “Property, plant and equipment” or “Intangible assets”) and lease obligations (presented in “Other financial liabilities (current)” and “Other financial liabilities (non-current))” For operating leases, lease payments are recognized as an expense on a straight-line basis over the lease term. Lessor The Group undertakes leasing activities involving property, plant and equipment as a lessor. The determination of whether an agreement contains a lease is based on the examination of the economic nature of the transactions regardless of the form of the lease. For finance leases, net investments in finance leases are recognized as lease receivables (presented in “Trade and other receivables”). Lease receivables are categorized into amounts equivalent to the principal and interest of lease receivables. Further, if the main purpose of a finance lease is the sale of products and the finance leases have been implemented in accordance with sales policies, the lower of the fair value of the assets subject to leases or minimum lease payment receivable discounted at the market rate of interest is recognized as revenue, and the purchase price of the leased assets is recognized in cost of sales. For operating leases, lease income is recognized on a straight line basis over the term of the lease. The respective leased assets are included in the statement of financial position based on their nature. (9) Impairment of property, plant and equipment, and intangible assets The Company assesses at the end of each reporting period whether there is an indication that an asset may be impaired. If any such indication exists, the Company recognizes impairment losses when its carrying amount exceeds its recoverable amount. The recoverable amount of an asset or CGU is the higher of fair value less costs of disposal and value in use. Value in use is determined as the present value of future cash flows expected to be derived from an asset or CGU. When it is not possible to estimate the recoverable amount of the individual asset, the recoverable amount of CGU to which the asset belongs is estimated. When the carrying amount of CGU exceeds the recoverable amount, the carrying amount is reduced to the recoverable amount and an impairment loss is recognized in profit or loss. An impairment loss for CGU is allocated to the assets on the basis of the relative carrying amount of each asset in the unit. The Group determines at the end of each reporting period whether there is any indication that an impairment loss recognized in prior years has decreased or extinguished. An impairment loss is reversed when there is an indication that there has been a change in the estimates used to determine an asset’s recoverable amount. When an impairment loss recognized is reversed, carrying amount of the asset is increased to its updated estimated recoverable amount. A reversal of an impairment loss is recognized, to the extent the increased carrying amount does not exceed the lower of the recoverable amount or the carrying amount (net of depreciation and amortization) that would have been determined had no impairment loss been recognized. A reversal of an impairment loss is recognized as “Other operating income.” (10) Financial instruments The Group applies the requirements for financial instruments under IFRS 9 “Financial Instruments” issued in July 2014. (a) Recognition and derecognition The Group initially recognizes a financial asset or a financial liability when it becomes a party to the contractual provisions of the instrument. The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred, or it neither transfers nor retains substantially all of the risks and rewards of ownership and does not retain control over the transferred asset. Any interest in such derecognized financial assets created or retained by the Group is recognized as a separate asset or liability. The Group derecognizes a financial liability when its contractual obligations are discharged, cancelled, or expire. The Group directly writes off the gross carrying amount of financial assets that are legally discharged (by court or relevant law) or where the Group has no reasonable expectations of recovering a financial asset in question in its entirety or a portion. (b) Offsetting Financial assets and liabilities are offset and the net amount is presented in the statement of financial position when, and only when, the Group has a legally enforceable right to offset the amounts and intends to settle them on a net basis or to realize the asset and settle the liability simultaneously. (c) Classification and measurement—financial assets Financial assets are classified as subsequently measured at amortized cost, fair value through other comprehensive income (“FVOCI”) or fair value through profit or loss (“FVPL”). A regular way purchase or sale of financial assets is recognized and derecognized, as applicable, using transaction date accounting or settlement date accounting. The Group applies the following dates to account for each classification of financial asset: •   Financial assets at amortized cost Settlement date accounting •   Financial assets at FVOCI Transaction date accounting •   Financial assets at FVPL Transaction date accounting (i) Financial assets at amortized cost A financial asset is measured at amortized cost if both of the following conditions are met: • the financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows, and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. These assets are initially measured at fair value plus any directly attributable transaction costs. Subsequent to initial recognition, they are measured at amortized cost using the effective interest method. The impairment requirements discussed below are also applied. (ii) Financial assets at FVOCI A financial asset is measured at FVOCI if both of the following conditions are met: • the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. (iii) Financial assets at FVPL A financial asset that is not measured at amortized cost or FVOCI is classified as measured at FVPL. It can also be designated as such on initial recognition. Directly attributable transaction costs are recognized in profit or loss as incurred. A gain or loss on a financial asset that is measured at FVPL is recognized in profit or loss. The Group may make an irrevocable election at initial recognition for particular investments in equity instruments that would otherwise be measured at FVPL to present subsequent changes in fair value in other comprehensive income. (iv) Investments in equity instruments designated at FVOCI After initial recognition, investments in equity instruments not held for trading that are designated as measured at FVOCI should be measured at fair value, with no deduction for sale or disposal costs. With the exception of dividends received, the associated gains and losses (including any related foreign exchange component) are recognized in OCI. Amounts presented in OCI are not subsequently reclassified to profit or loss. (d) Classification and measurement—financial liabilities Financial liabilities are classified either as subsequently measured at FVPL or at amortized cost. Financial liabilities are classified as at FVPL if it is classified as held-for-trading Financial liabilities at amortized cost are initially measured at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these liabilities are measured at amortized cost using the effective interest method. (e) Impairment Impairment is based on an expected credit loss (“ECL”) model. The Group applies a three-stage approach to measuring ECL on debt instruments accounted for at amortized cost and FVOCI. Assets migrate through the following three stages based on the change in credit quality since initial recognition: Stage 1: 12-month For exposure on debt instruments where there has not been a significant increase in credit risk since initial recognition and that were not credit impaired upon origination, the portion of the lifetime ECL associated with the probability of default events occurring within the next 12 months is recognized. Stage 2: Lifetime ECL—not credit-impaired For credit exposure on debt instruments where there has been a significant increase in credit risk since initial recognition but that are not credit impaired, a lifetime ECL is recognized. Stage 3: Lifetime ECL—credit-impaired Financial assets are assessed as credit impaired when one or more events that have detrimental impact on the estimated future cash flows of that asset have occurred. For financial assets that have become credit impaired, a lifetime ECL is recognized and interest income is calculated applying the effective interest rate to the amortized cost (net of provision) rather than the gross carrying amount. At each reporting date, the Group assesses whether there has been a significant increase in credit risk for financial assets since initial recognition by comparing the risk of default occurring over the expected life between the reporting date and the date of initial recognition. The indicators used by the Group to assess whether there is any objective evidence of impairment include: significant financial difficulties of the issuer or the borrower; breach of contract, such as default or past due event in interest or principal payment, or; probable event that borrower will enter bankruptcy or financial reorganization. If, in a subsequent period, credit quality improves and reverses any previously assessed significant increase in credit risk since origination, then the provision for doubtful debts reverts from lifetime ECL to 12-month The Group applies the simplified approach for all trade receivables and lease receivables, instead of the three-stages above. Under this approach, the Group does not track changes in credit risk, but instead recognizes loss allowances based on lifetime ECL upon origination and at each reporting date. (f) Derivatives and hedge accounting In order to hedge foreign currency risks, the Group utilizes derivative transactions including foreign exchange forward contracts. At the initiation of a transaction, the Group documents the relationship between the hedging instrument and the hedged item, along with the risk management objective and strategy for undertaking the hedge transaction. Additionally, at the inception of the hedge and on an ongoing basis, the Group assesses whether the derivative designated as hedging instrument meets the criteria for hedge accounting in offsetting changes in cash flows of the hedged item. Derivatives are initially recognized at fair value. For derivatives which do not meet the criteria for hedge accounting, subsequent changes in fair value are recognized in profit or loss. For derivatives which meet the criteria for hedge accounting, changes in fair value of derivatives that are designated and qualify as cash flow hedges are recognized in other comprehensive income. However, the ineffective portion of changes in the fair value of hedging derivatives is recognized in profit or loss. Amounts accumulated in other comprehensive income are reclassified to profit or loss in the period when the hedged item affects profit or loss. However, when the hedged forecast transaction subsequently results in the recognition of a non-financial Furthermore, hedge accounting is discontinued prospectively when cash flow hedges no longer meet the criteria for hedge accounting, or when the hedging instrument expires or is sold, terminated or exercised. (11) Borrowings Borrowings are initially recognized at fair value, net of transaction costs incurred and measured subsequently at amortized cost. Any difference between the proceeds, net of transaction costs, and the redemption amount is recognized in profit or loss over the period of the borrowings using the effective interest method. Fees paid on the financing of debt facilities are recognized as transaction costs of the debt to the extent that it is probable that some or all of the facility will be drawn down. (12) Borrowing costs Borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized during the period of time that is required to complete and prepare the asset for its intended use. Qualifying assets are assets that necessarily take a substantial period of time to get ready for their intended use. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are expensed in the period in which they are incurred. (13) Provisions and contingencies The consolidated financial statements include all provisions for which it is considered more likely than not that the corresponding obligation will have to be settled. Provisions are measured at the present value of the best estimate of the amount required to settle the obligation or transfer it, taking into account the information available on the event and its consequences. Adjustments arising from the discounting of the provision are recognized as finance costs when accrued. Any items of contingent liabilities that may have a material impact on business in the future are disclosed in light of all available evidence at the end of the reporting period and by taking into account the probability of these contingencies and their impact on financial reporting. (14) Employee benefits (a) Short-term employee benefits Short-term employee benefits are expensed as the related service is provided. A liability is recognized for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably. (b) Defined contribution plans Obligations for contributions to defined contribution plans are expensed as the related service is provided. (c) Defined benefit plans The Group’s net obligation related to defined benefit plans is calculated separately for each 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. The calculation of defined benefit obligations are performed annually by qualified actuaries using the projected unit credit method. Remeasurements of defined benefit liabilities, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. The Group determines the net interest expense on defined benefit liabilities for the period by applying discount rate used to measure the defined benefit obligations at the beginning of the annual period to the then defined benefit liabilities, taking into account any changes in defined benefit liabilities during the period as a result of contributions and benefit payments. Net interest expense and other operating expenses related to defined benefit plans are recognized in profit or loss. Actuarial gains and losses arising from the defined benefit plan are recognized immediately in other comprehensive income and directly reclassified to retained earnings from other components of equity. When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Group recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs. (15) Income taxes Income tax expense is comprised of current and deferred taxes, and it is recognized in profit or loss except for taxes arising from business combinations and transactions which are recognized directly in equity or in other comprehensive income. (a) Current tax Current tax is comprised of expected taxes payable or receivable on the taxable income or loss for the year and any adjustment to the taxes payable or receivable in respect of the previous years. The amount of current taxes payable or receivable is the best estimate of the tax amount expected to be paid or received that reflects uncertainty related to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any taxes arising from dividends. Current tax assets and liabilities are offset only if certain criteria are met. (b) Deferred tax Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognized for: • Temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss, and; • Temporary differences related to investments in subsidiaries, associates, and joint ventures to the extent that the Group is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future Deferred tax assets are recognized for unused tax losses, unused tax credits and deductible temporary differences to the extent that it is probable that future taxable profits will be available for utilization. Future taxable profits are estimated based on business plans for the Group. 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. Unrecognized deferred tax assets are reassessed at each reporting date and recognized to the extent that it has become probable that future taxable profits will be available against which they can be used. Deferred tax assets and liabilities are measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date. Deferred tax assets and liabilities are offset only if certain criteria are met. (16) Equity (a) Ordinary shares Common shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares are recognized as a deduction from equity, net of any related taxes. (b) Repurchase and sale of ordinary shares (treasury shares) When shares recognized as equity are repurchased, the amount of the consideration paid, which includes directly attributable costs, is recognized as a deduction from equity and presented as treasury shares. When treasury shares are sold subsequently, the consideration received is recognized as an increase in equity and the difference between the consideration received and the carrying amount is recognized in capital surplus. (17) Dividends Dividends to shareholders of the Company are recognized as a liability when such dividends are approved by the shareholders on or before the end of the reporting period but not yet distributed at the end of the reporting period. (18) Revenue recognition The Group adopted the new revenue recognition standard issued by IASB, IFRS 15 “Revenue from Contracts with Customer” from the year beginning on April 1, 2018. Before adoption of IFRS 15, the Group generally recognized revenue from sales of goods upon shipment or delivery, depending on when risk and rewards were transferred to customers. Revenue from rendering of services was recognized by reference to the stage of completion of the service at the end of the reporting period. Revenue was measured at the fair value of the consideration received or receivable, net of returns, trade discounts, volume rebates and consumption taxes. The Group has examined and concluded that the prior methods of revenue recognition and measurement were substantially in accordance with IFRS 15 and therefore no material adjustment was made to the beginning balance of the retained earnings under the modified retrospective method. Details of the revenue recognition policy of the Group are as follows. The Group recognizes revenue by applying the following steps: Step 1: Identify the contracts with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when or as the entity satisfies a performance obligation The Group engages in the manufacturing and selling of products such as electronic components, car navigation and audio systems and other products through the electronic components segment and the automotive infotainment segment. Revenue from sales of these products is recognized upon shipment or delivery, depending on when the control over the products is considered transferred to the customer based on sales agreements. The Group also renders transportation, storage, forwarding services, system development, and

Segment information	4. Segment information (1) Reportable segments Operating segments are defined as the components of the Group for which separate financial information is available that is evaluated regularly by the chief operating decision maker in making resource allocation decisions and in assessing performance. The Group is composed of segments determined by products and services and implements business activities based on its comprehensive strategies. The reportable segments are classified by products and services taking into account the commonality of the types of products and markets. The Company has three operating segments, namely, “Electronic Components,” “Automotive Infotainment” and “Logistics,” which are also the Company’s reportable segments as no operating segments have been aggregated to form reportable segments. “Other” includes relatively less significant businesses. Reportable segments Operations Electronic Components Development, manufacturing and marketing of a variety of electronic components, including sensors, TACT Switch TM Automotive Infotainment Development, manufacturing, and marketing of audio, information and communication products, including head units, audio visual, road navigation systems and speakers mainly for the automotive sector. Logistics Provision of transportation, storage and forwarding services. The chief operating decision maker primarily evaluates segment performance based on figures as reported under Japanese GAAP as such information is most relevant in evaluating the results of the respective segments relative to entities that operate in the same industries. The reconciliations of reportable segment information, which is prepared under Japanese GAAP figures, to consolidated amounts under IFRS were as follows: For the year ended March 31, 2017 (Millions of yen) Reportable segments Other* 1 Adjustments* 2 Consolidated GAAP IFRS 4 Consolidated IFRS Electronic Automotive Logistics Total Revenue External 437,677 242,307 61,151 741,135 12,128 — 753,263 (1,700 ) 751,563 Inter-segment 10,019 5,445 38,099 53,563 13,254 (66,817 ) — — — Total 447,696 247,752 99,250 794,698 25,382 (66,817 ) 753,263 (1,700 ) 751,563 Segment profit* 3 32,803 5,624 5,084 43,511 885 (22 ) 44,374 (2,631 ) 41,743 Reconciling items Finance income 1,076 Finance costs (1,334 ) Profit for the year before income tax under IFRS 41,485 Other items -Depreciation and amortization 24,139 6,418 2,128 32,685 381 10 33,076 305 33,381 -Capital expenditures 37,063 7,979 2,072 47,114 493 50 47,657 1,229 48,886 As of and for the year ended March 31, 2018 (Millions of yen) Reportable segments Other* 1 Adjustments* 2 Consolidated GAAP IFRS 5 Consolidated IFRS Electronic Automotive Logistics Total Revenue External 514,032 267,639 64,666 846,337 11,981 — 858,318 (786 ) 857,532 Inter-segment 13,861 7,643 40,306 61,810 14,175 (75,985 ) — — — Total 527,893 275,282 104,972 908,147 26,156 (75,985 ) 858,318 (786 ) 857,532 Segment profit* 3 52,930 13,735 4,933 71,598 1,701 (1,392 ) 71,907 (3,248 ) 68,659 Reconciling items Finance income 1,146 Finance costs (4,235 ) Profit for the year before income tax under IFRS 65,570 Other items -Depreciation and amortization 26,308 7,035 2,184 35,527 453 25 36,005 919 36,924 -Capital expenditures 61,236 8,611 5,584 75,431 663 60 76,154 (569 ) 75,585 Segment assets 413,899 218,903 76,344 709,146 38,689 (76,036 ) 671,799 29,388 701,187 Segment liabilities 180,260 63,217 27,015 270,492 32,024 (46,590 ) 255,926 19,464 275,390 As of and for the year ended March 31, 2019 (Millions of yen) Reportable segments Other* 1 Adjustments* 2 Consolidated GAAP IFRS 6 Consolidated IFRS Electronic Automotive Logistics Total Revenue External 468,606 303,594 66,888 839,088 12,245 — 851,333 (858 ) 850,475 Inter-segment 15,664 7,577 38,030 61,271 14,994 (76,265 ) — — — Total 484,270 311,171 104,918 900,359 27,239 (76,265 ) 851,333 (858 ) 850,475 Segment profit* 3 29,607 13,922 4,722 48,251 1,430 (40 ) 49,641 (8,015 ) 41,626 Reconciling items Finance income 1,363 Finance costs (3,429 ) Profit for the year before income tax under IFRS 39,560 Other items -Depreciation and amortization 33,995 7,412 2,288 43,695 456 37 44,188 1,147 45,335 -Capital expenditures 33,210 13,597 5,533 52,340 563 25 52,928 8,305 61,233 Segment assets 473,867 218,144 75,604 767,615 44,058 (135,955 ) 675,718 35,610 711,328 Segment liabilities 198,581 79,632 25,082 303,295 37,819 (60,758 ) 280,356 19,906 300,262 *1 “Other” includes business segments not included in the reportable segments, and includes the development of information systems, office services, financing and leasing businesses. *2 Adjustments consist of the following: 1.

Product warranty provisions are estimated primarily based on historical experience and measured at the amounts expected to be incurred in the future to replace or repair the defective products sold. These expenditures are required to be settled based on customer request and are frequently paid over several years. Provisions for environmental measures are recognized based on reasonable estimates of the industrial waste handling expenditures expected to be incurred in the future. The timing of these expenditures will depend on future business plans and other plans. Decommissioning obligations are recognized when the Group is obligated to dismantle and remove facilities or equipment and restore the site, and when reliable estimates can be made of the amounts of its obligations. The timing of these expenditures depends on future business plans.

The maximum aggregate purchase price for purchases under the program was set at 28,400 million yen, representing approximately 40,000 million yen less the 11,570 million yen that Alpine was expected to pay, in accordance with Article 786, paragraph 5 of the Companies Act, to its former shareholders who had requested Alpine to purchase their shares in connection with the share exchange.

(3) Deferred tax assets and deferred tax liabilities The movements by significant component of deferred tax assets and deferred tax liabilities for the years ended March 31, 2017, 2018 and 2019 were summarized as follows: For the year ended March 31, 2017 (Millions of yen) As of Recognized in Recognized in Others As of March 31, 2017 Deferred tax assets: Property, plant and equipment 7,134 1,567 — (2 ) 8,699 Inventories 2,825 370 — — 3,195 Accrued employee bonuses 2,283 233 — — 2,516 Defined benefit liabilities 6,112 22 (710 ) (26 ) 5,398 Other employee benefits 1,905 85 — — 1,990 Loss allowances 874 72 — — 946 Accrued expenses 572 121 — — 693 Provision for product warranty 818 37 — — 855 Accrued enterprise taxes 279 25 — — 304 Tax credits 595 22 617 Tax loss carryforwards 9,693 (1,169 ) — — 8,524 Others 5,457 (389 ) — (85 ) 4,983 Total 38,547 996 (710 ) (113 ) 38,720 Deferred tax liabilities: Undistributed earnings of subsidiaries 4,358 (1,214 ) — — 3,144 Financial assets measured at fair value 13,089 (2,771 ) 380 — 10,698 Others 3,327 (966 ) — 20 2,381 Total 20,774 (4,951 ) 380 20 16,223 For the year ended March 31, 2018 (Millions of yen) As of April 1, 2017 Recognized in profit or loss Recognized in Others As of March 31, 2018 Deferred tax assets: Property, plant and equipment 8,699 (502 ) — 121 8,318 Inventories 3,195 (112 ) — 89 3,172 Accrued employee bonuses 2,516 122 — — 2,638 Defined benefit liabilities 5,398 (59 ) (1,048 ) 26 4,317 Other employee benefits 1,990 43 — — 2,033 Loss allowances 946 (45 ) — — 901 Accrued expenses 693 (120 ) — 9 582 Provision for product warranty 855 (128 ) — — 727 Accrued enterprise taxes 304 112 — — 416 Tax credits 617 79 696 Tax loss carryforwards 8,524 (3,968 ) — — 4,556 Others 4,983 (1,735 ) — 181 3,429 Total 38,720 (6,313 ) (1,048 ) 426 31,785 Deferred tax liabilities: Undistributed earnings of subsidiaries 3,144 846 — — 3,990 Financial assets measured at fair value 10,698 — (944 ) — 9,754 Others 2,381 (1,038 ) — (50 ) 1,293 Total 16,223 (192 ) (944 ) (50 ) 15,037 For the year ended March 31, 2019 (Millions of yen) As of April 1, 2018 Recognized in profit or loss Recognized in Others As of March 31, 2019 Deferred tax assets: Property, plant and equipment 8,318 1,135 — — 9,453 Inventories 3,172 843 — — 4,015 Accrued employee bonuses 2,638 207 — — 2,845 Defined benefit liabilities 4,317 703 845 — 5,865 Other employee benefits 2,033 616 — — 2,649 Loss allowances 901 (590 ) — — 311 Accrued expenses 582 322 — — 904 Provision for product warranty 727 439 — — 1,166 Accrued enterprise taxes 416 (199 ) — — 217 Tax credits 696 277 — — 973 Tax loss carryforwards 4,556 386 — — 4,942 Others 3,429 1,134 — 191 4,754 Total 31,785 5,273 845 191 38,094 Deferred tax liabilities: Undistributed earnings of subsidiaries 3,990 (89 ) — — 3,901 Financial assets measured at fair value 9,754 — 508 — 10,262 Others 1,293 1,268 — — 2,561 Total 15,037 1,179 508 — 16,724 Deferred tax assets and deferred tax liabilities recognized in the consolidated statements of financial position were as follows: (Millions of yen) As of March 31, 2018 2019 Deferred tax assets 25,876 26,100 Deferred tax liabilities (9,128 ) (4,730 ) 16,748 21,370 The Group considers the probability that a portion of or all of the future deductible temporary differences and tax losses carryforward can be utilized against future taxable profits on recognition of deferred tax assets. In assessing recoverability of deferred tax assets, the Group considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. Based on the level of historical taxable profits and projected future taxable income during the periods for which deferred tax assets are deductible, the Group believes that it is probable that the tax benefits of these deferred tax assets can be utilized at the end of each period. Uncertainty of estimates of future taxable income could increase due to changes in the economic environment, market conditions or other factors surrounding the Group. (4) Deferred tax assets which are not recognized The amounts of deductible temporary differences and unused tax loss carryforward for which no deferred tax assets were recognized as of March 31, 2018 and 2019 were as follows: (Millions of yen) As of March 31 2018 2019 Deductible temporary differences 35,816 20,557 Unused tax loss carryforwards 10,485 10,323 Unused tax credits 1,716 1,458 The Company has elected to apply the Japanese tax consolidation filing system to it and its wholly owned Japanese subsidiaries. Alpine Electronics, Inc. became a member of the consolidated tax return group from January 1, 2019, the effective date of the share exchange when Alpine became a wholly-owned subsidiary of the Company. Alpine Electronics, Inc. did not recognize any deferred tax assets as of March 31, 2018, since taxable income was not recorded in recent years and recoverability of deferred tax assets were considered not probable. However, certain deferred tax assets of Alpine relating to deductible temporary differences that did not meet the recognition criteria previously, based on an assessment of recoverability as a stand-alone entity, were judged to meet the criteria for recognition from the perspective of the Group as a consolidated group for tax purposes. The recoverability of Alpine’s deferred tax assets were assessed in terms of whether it is probable that the Group has the ability to generate future taxable income sufficient to utilize the deductible temporary differences. As a result of this assessment based on management estimates, The Group recognized deferred tax assets of 4,680 million yen as of March 31, 2019, which had not been recognized by Alpine prior to the share exchange. The expiry dates of tax loss carryforwards for which deferred tax assets are not recognized as of March 31, 2018 and 2019 were as follows: (Millions of yen) As of March 31, 2018 2019 Within 1 year 10 40 Between 1 and 5 years 156 409 Over 5 years 10,319 9,874 Total 10,485 10,323 The expiry dates of tax credits for which deferred tax assets are not recognized as of March 31, 2018 and 2019 were as follows: (Millions of yen) As of March 31, 2018 2019 Within 1 year 14 12 Between 1 and 5 years 151 720 Over 5 years 1,551 726 Total 1,716 1,458 (5) Temporary differences related to investments in subsidiaries for which deferred tax liabilities are not recognized As for future taxable temporary differences related to investments in subsidiaries, the Group did not recognize deferred tax liabilities except for those related to the undistributed retained earnings at the end of the reporting period from which dividends to the Company will be paid, because the Company is able to control the timing of reversing the temporary differences, and the temporary differences will not be reversed in the foreseeable future. Future taxable temporary differences related to investments in subsidiaries for which no deferred tax liabilities have been recognized were 63,937 million yen and 54,706 million yen as of March 31, 2018 and 2019, respectively, and the tax rate which would be applicable to such unrecognized future taxable temporary differences was primarily 10%.

Financial instruments	29. Financial instruments (1) Capital management Amid market innovation brought about by the fourth industrial revolution, the Group decided to conduct the business integration between Alps and Alpine. The Group aims to keep contributing to people’s lives in the areas of electronics and communications by focusing on the electronic components business and the automotive infotainment business and to significantly transform itself into a sustainable value-creating corporate group with net sales of one trillion yen on a Japanese GAAP basis. To meet this objective, the Group believes that it is important to first secure a sound financial base, and then to pursue the maximization and sustainable increase of its corporate value, which are to be achieved through the dual pillars of investment in sustainable growth and capital efficiency improvements. Based on the above, the Group reviews the appropriate capital level against medium- long-term a) Maintain a financial position that can withstand rapid changes in the business environment and any unforeseen economic crisis in the future; b) Maintain a rating necessary to engage in business worldwide; and c) Secure capital necessary to sustain the medium- long-term The measures the Group focuses on for capital management purposes are equity ratio and interest-bearing debt. The following table provides details of such measures as of March 31, 2018 and 2019: (Millions of yen) As of March 31 2018 2019 Total equity 425,797 411,066 Total assets 701,187 711,328 Equity ratio 0.61 0.58 Borrowings 70,270 108,630 Finance lease obligations 2,536 3,055 Interest-bearing debt 72,806 111,685 The measures are reported to and monitored by management regularly. The Group is not subject to any particularly significant capital requirements, other than general rules such as those specified in the Companies Act of Japan. (2) Basic policy on financial risk management The Group is exposed to financial risks such as market risk (mainly foreign exchange risk and interest rate risk), credit risk and liquidity risk from its underlying business activities. The Group adopts necessary policies to avoid or mitigate such risks. Under the Group policy, derivative transactions that are speculative or targeted for short-term trading gains are prohibited, and only transactions for financial risk management purposes are permitted. (3) Credit risk (a) Credit risk management and maximum exposure to credit risk Credit risk refers to the risk of a counterparty failing to fulfill contractual obligations, which would result in a financial loss for the Group. Financial instruments that expose the Group to credit risk consist of trade and other receivables and other financial assets. In accordance with the Company’s credit control rules, the related Sales Department manager monitors credit limit of major customers, and the Credit Control Department assesses the financial conditions of the customers periodically. Receivables are considered to be in default, partially or fully, when it is determined that they are uncollectible or will be difficult to collect. The Company determines there has been a significant increase in credit risk of financial assets since initial recognition in cases where the cash collection of the financial assets is delayed and this delay is not due to a temporary cash shortage of the counterparty. Monitoring includes periodic review of balances and due dates for each major customer and review of the respective credit limit, for the purpose of early detection of doubtful accounts due to deteriorated financial conditions of the customers and to mitigate credit risk. The Company’s subsidiaries implement the same controls as the Company’s credit control rules. Derivative transactions to mitigate foreign exchange rates are entered into with highly creditworthy financial institutions. As such, the impact on credit risk is limited. (i) Responses to risks owned by the Group—Measurement of expected credit losses on trade receivables Receivables held by the Group are due from various counterparties, mainly in the electronics and automotive industries and across various geographic regions. Accordingly, the Group does not have significant concentration of credit risk related to particular counterparties or any other excessive concentration of credit risk requiring special attention. As trade receivables do not contain a significant financing component, the Group measures loss allowances at an amount equal to the lifetime expected credit losses until the trade receivables are recovered. As trade receivables comprise a number of customers, the Group measures expected credit loss collectively by grouping those receivables and considering historical credit loss experience. When those receivables are affected by material economic changes, the provision rate calculated based upon the historical credit loss experience is adjusted to reflect current and future economic prospects. Even when a late payment or request for grace period arises, the Group does not regard the related receivable as past due if such late payment or request for grace period is judged to be attributable to a temporary cash shortage, the risk of default is considered to be low and the debtors are evaluated to have sufficient ability to fulfill their contractual cash flow obligations in the near future. (ii) Responses to risks owned by the Group—Measurement of expected credit losses on other receivables When credit risk related to other receivables has not increased significantly since initial recognition of the other receivables at the end of the reporting period, the Group determines the amount of loss allowances by estimating the 12-months When there has been a significant increase in credit risk since initial recognition as of the end of the fiscal year, the Group estimates the lifetime credit losses individually and measures the amount of loss allowances based upon historical credit loss experience and future recoverable amount. The Group’s maximum exposure to credit risk equals the carrying amounts of the financial assets, net of loss allowances, as presented on the consolidated statements of financial position. (b) Changes in loss allowances Changes in the balances of loss allowances for the years ended March 31, 2018 and 2019 were as follows: For the year ended March 31, 2018 (Millions of yen) Lifetime expected credit loss 12-month Financial assets that are Financial assets Financial assets for which the allowance for doubtful accounts is always measured at an amount equal to lifetime expected credit loss Total Balance at beginning of year 6 2,909 — 297 3,212 Provision 17 30 — 299 346 Write-off — (1 ) — (31 ) (32 ) Reversal (3 ) (215 ) — (182 ) (400 ) Currency exchange differences 0 (1 ) — 10 9 Balance at end of year 20 2,722 — 393 3,135 For the year ended March 31, 2019 (Millions of yen) Lifetime expected credit loss 12-month Financial assets that are Financial assets Financial assets for which the allowance for doubtful accounts is always measured at an amount equal to lifetime expected credit loss Total Balance at beginning of year 20 2,722 — 393 3,135 Provision 1 832 — 164 997 Write-off — (65 ) — (27 ) (92 ) Reversal (6 ) (2,647 ) — (242 ) (2,895 ) Currency exchange differences — — — (5 ) (5 ) Balance at end of year 15 842 — 283 1,140 (c) Carrying amounts of financial assets related to loss allowances The carrying amounts of financial assets related to loss allowances as of March 31, 2018 and 2019 were as follows: (Millions of yen) As of March 31 2018 2019 12-month 6,877 6,229 Financial assets that are credit-impaired at the reporting date 2,735 807 Financial assets for which credit risk has increased significantly since initial recognition but that are not credit-impaired financial assets — — Financial assets for which the allowance for doubtful accounts is always measured at an amount equal to lifetime expected credit loss 161,652 156,803 (d) Credit risk analysis Aging of trade receivables and lease receivables that are not credit impaired as of March 31, 2018 and 2019 were as follows: (Millions of yen) As of March 31 2018 2019 Current 152,089 139,400 Past due within 30 days 6,186 10,576 Past due between 31 and 90 days 1,483 4,562 Past due over 90 days 1,894 2,265 Total 161,652 156,803 (4) Liquidity risk (a) Liquidity risk management The Company manages liquidity risk by preparing cash flow plans, which are revised on a regular basis based on the business plan, as well as through maintaining a certain minimum level of liquidity. The Company’s subsidiaries also manage liquidity risk in the same manner. The Company has also entered into syndicated committed credit line agreements with banks to manage its liquidity risk. The Company and its subsidiaries maintained committed credit lines of 40,000 million yen as of March 31, 2018 and 2019. The amounts of undrawn committed borrowing facilities are short-term borrowings of 39,100 million yen and 40,000 million yen as of March 31, 2018 and 2019, respectively. (b) Maturities of financial liabilities The maturities of financial liabilities as of March 31, 2018 and 2019 were as follows: Balance as of March 31, 2018 (Millions of yen) Carrying Contractual cash flows Within 1 year Over 2 years Over 2 years but no 3 years Over 4 years Over 5 years More than 5 years Non-derivative Trade and other payables 121,931 121,931 121,931 — — — — — Borrowings 70,270 70,704 36,850 6,924 24,423 1,505 1,002 — Finance lease obligations 2,536 3,035 657 491 273 221 191 1,202 Deposits received 2,501 2,501 1,982 7 8 7 — 497 Subtotal 197,238 198,171 161,420 7,422 24,704 1,733 1,193 1,699 Derivative liabilities 2 2 2 — — — — — Total 197,240 198,173 161,422 7,422 24,704 1,733 1,193 1,699 Balance as of March 31, 2019 (Millions of yen) Carrying Contractual cash flows Within 1 year Over later than Over Over Over More than 5 years Non-derivative Trade and other payables 112,951 112,951 112,951 — — — — — Borrowings 108,630 109,892 36,380 30,721 1,612 11,106 30,073 — Finance lease obligations 3,055 3,795 662 506 445 415 400 1,367 Deposits received 2,016 2,016 1,402 188 5 7 — 414 Subtotal 226,652 228,654 151,395 31,415 2,062 11,528 30,473 1,781 Derivative liabilities 158 158 158 — — — — — Total 226,810 228,812 151,553 31,415 2,062 11,528 30,473 1,781 (5) Market risk The Group’s market risk primarily consists of currency risk and interest rate risk. The objective of market risk management is to manage and control market risk exposure within acceptable parameters. (a) Currency risk Currency exchange risk management Trade receivables and trade payables denominated in foreign currency arising from overseas businesses are exposed to foreign currency risk. The Group’s foreign exchange risk arises mainly from US dollar and Euro fluctuations. The Group implements continuous monitoring of the exchange rates movements and management of foreign exchange exposures to manage currency risk. The Group utilizes forward exchange contracts to mitigate the currency risk. Sensitivity analysis for currency exchange rates For financial assets and liabilities held by the Group as of March 31, 2018 and 2019, the impact on profit before income taxes had the Japanese Yen appreciated 1% against the US dollar and Euro, assuming all other variables are held at a constant, was as follows: (Millions of yen) For the year ended March 31 Currency 2018 2019 Impact on profit before income taxes US dollar (297 ) (331 ) Euro (40 ) (73 ) The above analysis does not include financial assets and liabilities denominated in the functional currency and the effect of translating assets and liabilities of foreign operations into Japanese Yen. (b) Interest rate risk Interest rate risk management The Group is financed by borrowings, some of which bear variable interests and expose the Group to interest rate risk. To mitigate this risk, the Group enters into interest rate swap contracts for those floating rate borrowings with a variable interest rate in order to fix the interest expense. Sensitivity analysis for interest rates For floating rate borrowings held by the Group as of March 31, 2018 and 2019, the impact on profit before income taxes had the interest rate increased by 1%, assuming all other variables are held at a constant, was as follows: (Millions of yen) For the year ended March 31 2018 2019 Impact on profit before income taxes (498 ) (791 ) (6) Fair values of financial instruments The carrying amounts and fair values of financial instruments as of March 31, 2018 and 2019 were as follows: (Millions of yen) As of March 31 2018 2019 Carrying Fair value Carrying Fair value Borrowings 70,270 70,338 108,630 108,586 For financial liabilities in the above table, the fair value is calculated based on the discounted value of contractual cash flows. The fair values are considered to be Level 3 in the fair-value hierarchy. The calculation is performed by the Company reflecting the nature of assets or liabilities, characteristics and risks of individual assets or liabilities. Management assessed that the fair values of financial assets and liabilities with maturities of less than one year, other than derivatives, approximate their carrying amounts due to the short-term maturities of these instruments. As of March 31, 2018 and 2019, there are no significant variances between the fair value and the carrying amount of long-term loan receivables and long-term deposits received. (7) Fair value hierarchy of financial instruments Financial instruments subsequently measured at fair value after initial recognition on a recurring basis are classified into the following three levels of the fair value hierarchy, based on the degree to which the inputs to the fair value measurements are observable and the significance of the inputs to the fair value measurement in its entirety. Level 1: Fair value measured by quoted prices in active markets for identical assets or liabilities Level 2: Fair value measured by direct or indirect observable inputs other than Level 1 Level 3: Fair value measured by significant unobservable inputs The Group recognizes transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer. For the years ended March 31, 2018 and 2019, there were no transfers between Level 1 and Level 2 and no transfers in and out of Level 3. The following tables present the levels at which the fair values measured on a recurring basis are classified as of March 31, 2018 and 2019: As of March 31, 2018 (Millions of yen) Level 1 Level 2 Level 3 Total Financial assets Financial assets measured at fair value through other comprehensive income: Equity securities 41,865 — 11,016 52,881 Financial assets measured at fair value through profit or loss: Derivative assets — 680 — 680 Total 41,865 680 11,016 53,561 Financial liabilities Financial liabilities measured at fair value through profit or loss: Derivative liabilities — 2 — 2 Total — 2 — 2 As of March 31, 2019 (Millions of yen) Level 1 Level 2 Level 3 Total Financial assets Financial assets measured at fair value through other comprehensive income: Equity securities 37,624 — 18,112 55,736 Financial assets measured at fair value through profit or loss: Derivative assets — 34 — 34 Total 37,624 34 18,112 55,770 Financial liabilities Financial liabilities measured at fair value through profit or loss: Derivative liabilities — 158 — 158 Total — 158 — 158 The fair values of listed equity securities traded in active markets are calculated based on directly observable market values, and as such are categorized as Level 1. The fair values of unlisted equity securities with no active market for which fair values are calculated based on significant unobservable inputs reflecting the assumptions of market participants are categorized as Level 3. The fair value measurement process for Level 3 financial instruments is performed by adopting valuation models that can best reflect the characteristics and risks of individual financial instruments. In addition, the Company also monitors the trends of significant indicators that could have an effect on their fair values and financial conditions of the issuer. Valuation of these financial instruments is performed by primarily referring to most recent transaction prices for the same instrument. In certain cases, valuation is made through comparison with the listed equity prices of similar companies with appropriate adjustments using reasonably available inputs, which would be used by market participants. Unobservable inputs are used for measurement of fair value of unlisted securities. The significant unobservable input used for measurement of Level 3 financial instruments measured at fair value is actual transaction prices or P/B ratio (price-to-book For the years ended March 31, 2018 and 2019, changes in the fair value of Level 3 financial instruments measured at fair value on a recurring basis were as follows: Equity instruments measured at fair (Millions of yen) For the year ended March 31, 2018 2019 Balance at the beginning of the year 10,966 11,016 Total income (losses) recognized in other comprehensive income (114 ) 7,113 Sales — (19 ) Purchases 164 2 Balance at the end of the year 11,016 18,112 (8) Derivative transactions and hedging activities The Group uses derivative financial instruments, including foreign exchange forward contracts, to hedge future cash flow fluctuation risk due to foreign exchange. As of March 31, 2018 and 2019, the Group did not apply hedge accounting for all the derivatives. Derivative financial instruments are included in “Other financial assets” or “Other financial liabilities” in the consolidated statements of financial position. Fair value and notional amount of derivatives to which hedge accounting is not applied were as follows: As of March 31, 2018 (Millions of yen) Fair value Notional amount Asset Liability Foreign exchange forward contracts 39,429 680 2 As of March 31, 2019 (Millions of yen) Fair value Notional amount Asset Liability Foreign exchange forward contracts 21,316 34 158

This was because Alpine was bound contractually by the Alps Group Operation and Management Agreement the “Group Management Agreement,” which allowed Alps to assert control over Alpine under IFRS 10 Consolidated Financial Statements. On January 1, 2019, pursuant to the Share Exchange Agreement, the Company acquired additional interest in Alpine, increasing its ownership interest to 100%. See Note 19 (1)“Share capital and capital surplus” for more information. The following is the condensed financial statements of the Alpine Group. Alpine Group (a) General information As of March 31 2018 2019 Share of ownership held by non-controlling 58.97 0.00 Voting rights held by non-controlling 58.85 0.00 (b) Condensed consolidated financial statements (i) Condensed consolidated statements of financial position (Millions of yen) As of March 31 2018 2019 Current assets 138,624 136,700 Non-current 95,328 105,879 Current liabilities 55,657 76,961 Non-current 16,959 12,267 Total equity 161,336 153,351 Accumulated non-controlling 95,140 — (ii) Condensed consolidated statements of profit or loss and other comprehensive income or loss (Millions of yen) For the year ended March 31 2017 2018 2019 Revenue 243,483 268,575 303,309 Net profit for the year 1,992 7,526 10,884 Other comprehensive income (loss), net of taxes (2,891 ) (3,082 ) 2,103 Comprehensive income (loss) for the year, net of taxes (899 ) 4,444 12,987 Net profit for the year attributable to non-controlling 1,174 4,438 5,093 Dividends paid to non-controlling 1,219 1,220 5,248 * On September 27, 2018, Alpine’s board of directors resolved to submit to an extraordinary general meeting of shareholders a proposal for the approval of special dividends of 100 yen per share of Alpine common stock on the condition that the Share Exchange Agreement was approved by Alpine shareholders at an extraordinary meeting of shareholders. The Share Exchange Agreement was approved on December 5, 2018 and the proposal of special dividends was resolved on the same date. The aggregate amount of such dividends was 6,895 million yen including those paid to the Group and certain of its subsidiaries, and the Group’s cash and cash equivalents were reduced by 4,067 million, the amount that was paid to Alpine shareholders other than the Company and certain of its subsidiaries. The special dividends were paid on December 27, 2018. (iii) Condensed consolidated statements of cash flows (Millions of yen) For the year ended March 31, 2017 2018 2019 Cash flows provided by operating activities, net 4,145 14,261 13,032 Cash flows provided by (used in) investing activities, net 2,715 (12,760 ) (16,342 ) Cash flows used in financing activities, net (2,163 ) (2,124 ) (7,548 ) Net increase (decrease) in cash and cash equivalents 4,026 396 (11,420 ) (3) Condensed financial statements of subsidiaries with significant non-controlling Alps Logistics, publicly listed in Japan, and its respective subsidiaries (Alps Logistics and its subsidiaries, the “Alps Logistics Group”) are consolidated subsidiaries of the Company even though the Company holds less than half of the voting rights of Alps Logistics. Alps Logistics is bound contractually by the Alps Group Operation and Management Agreement (the “Group Management Agreement”), which establishes management principles and gives the Company the right to direct the operations of Alps Logistics Group. The Group Management Agreement grants Alps rights as to determination of actions submitted to the Alps Logistics Shareholders’ Meetings for a vote, and specifies very detailed rights over each of their operations. Specifically, such rights include: the ability to dispatch directors to Alps Logistics; the ability to lead group CEO meetings to discuss key operating matters in advance of a shareholder vote at Alps Logistics; the ability to participate in the decision-making process over management policy, finance policy and business strategy of the Alps Logistics groups; and the ability to manage financial performance through periodic reporting and business reviews, including internal audit procedures. In addition to these rights, Alps has had a history of representing the majority of votes on matters submitted to a vote at Shareholders’ Meetings of Alps Logistics, and the other shareholders are relatively widely dispersed without significant concentrations. Such governance framework and other conditions provide substantive rights to the Company to establish operating and financing decisions, including key personnel human resource policies, which reflects control over Alps Logistics under IFRS 10 Consolidated Financial Statements.

Significant accounting policies (Policies)	12 Months Ended

Text block [abstract]
Basis of consolidation	(1) Basis of consolidation (a) Subsidiaries The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Group. Control is achieved when the Group has power over the investee, is exposed, or has rights, to variable returns from its involvement with the investee, and has the ability to use its power to affect its returns. The Group reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. The financial statements of the subsidiaries are consolidated into the consolidated financial statements of the Group from the date when the Group obtains control over a subsidiary until the date the Group loses control of the subsidiary. Additionally, the financial statements of subsidiaries are adjusted to conform to the accounting policies adopted by the Group, as necessary. The Group treats transactions with non-controlling non-controlling non-controlling Intercompany transactions, balances and unrealized gains on transactions between group companies are eliminated upon consolidation. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. When the Group ceases to have control over a subsidiary, any retained interest in the entity is remeasured to its fair value on the date when control is lost, with the change in the carrying amount recognized in profit or loss in its entirety. (b) Associates and joint ventures Associates are entities over which the Group has significant influence, but not control or joint control, over management decision-making in relation to their financial and operating policies. Significant influence is the power to participate in the financial and operating policy decisions of the entity. Joint control is a contractual arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. Joint arrangements are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each party. Joint ventures are joint arrangements whereby the parties who have joint control of the arrangement have the rights to the net assets of the arrangement. Investments in interests in associates and joint ventures are accounted for using the equity method. Under the equity method, investments in interests are initially recognized at cost, and adjusted for changes in the net assets of associates and joint ventures that arise after the date of the acquisition. When the Group’s interest in an associate or a joint venture is reduced, but the investment continues to be classified as an associate or a joint venture respectively, the Group reclassifies to profit or loss the proportion of the related gain or loss that had previously been recognized in other comprehensive income (“OCI”) corresponding to that reduction in ownership interest. However, where the investment ceases to be classified as an associate or joint venture but is classified as a financial asset, the Group measures the retained interest at fair value in accordance with IFRS 9, and recognizes in profit or loss any difference between such fair value and the carrying amount at the date the equity method was discontinued. The Group’s share of operating results of associates and joint ventures is adjusted to conform to the Group’s accounting policy and recognized as “Share of profit or loss of associates and joint ventures accounted for using the equity method” in the consolidated statements of profit or loss. Unrealized gains or losses on transactions are eliminated to the extent of the Group’s interest in the investee. Impairment in respect of an equity-method investee is measured by comparing the recoverable amount of the investment with its carrying amount. An impairment is recognized in profit or loss, and is reversed if there has been a favorable change in the estimates used to determine the recoverable amount.
Foreign currency transactions	(2) Foreign currency transactions (a) Foreign currency transactions Foreign currency transactions are converted into the functional currency of each company using foreign currency exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date. Non-monetary Non-monetary (b) Translation of foreign operations The assets and liabilities of foreign operations, which use a functional currency other than Japanese yen are translated into Japanese yen at exchange rates at the reporting date. Income and expenses of foreign operations are translated into Japanese yen at exchange rates at the dates of the transactions, which are approximated using average exchange rates, unless the exchange rates fluctuate significantly. Foreign currency differences are recognized in OCI and accumulated in the foreign currency translation reserve in other components of equity, except to the extent that the translation difference is allocated to NCI. When a foreign operation is disposed of in its entirety or partially such that control or significant influence is lost, the cumulative amount in the foreign currency translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal. If the Group disposes of part of its interest in a subsidiary but retains control, the relevant proportion of the cumulative amount is reattributed to NCI. When the Group disposes of only part of an associate while retaining significant influence, the relevant proportion of the cumulative amount is reclassified to profit or loss.
Segment reporting	(3) Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker is responsible for allocating resources and assessing performance of the operating segments and is considered to be the board of directors of the Company.
Cash and cash equivalents	(4) Cash and cash equivalents Cash and cash equivalents include cash on hand, deposits held at call with financial institutions, other short-term, highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value.
Inventories	(5) Inventories Inventories are valued at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business less the estimated selling costs. The costs of inventories include direct materials, direct labor and an appropriate proportion of variable and fixed overhead expenditure, which are allocated on the basis of normal operating capacity. Costs are assigned to individual items of inventory on the basis of weighted average costs. Costs of purchased inventory are determined after deducting rebates and discounts.
Property, plant and equipment	(6) Property, plant and equipment Property, plant and equipment are measured initially at cost and subsequently carried at the amount net of any accumulated depreciation and any accumulated impairment losses. Costs incurred to enlarge, upgrade or improve the items that increase productivity, capacity or efficiency, or extend the useful lives of the assets are capitalized as an increase in the cost of the related asset, while repairs and maintenance expenses are charged to expense as incurred. The depreciable amount is the cost of the asset less the estimated residual values. The Group depreciates its property, plant and equipment primarily using the straight-line method over the useful lives, as follows: Years of useful lives Buildings and structures 2 – 50 Machinery, equipment and vehicles 1 – 17 Tools, furniture and fixtures 1 – 20 The depreciation methods, useful lives and residual values are reviewed at the end of each reporting period, and any necessary changes are applied prospectively as a change in accounting estimate. Gains or losses arising from the sales or disposals of an asset are determined as the difference between the carrying amount of the asset and its sales proceeds and recognized in “Other operating income” or “Other operating expenses” in the consolidated statements of profit or loss.
Intangible assets	(7) Intangible assets Intangible assets are measured initially at cost of acquisition or development. After initial recognition, intangible assets are carried at cost less accumulated amortizations and any accumulated impairment losses. Intangible assets acquired separately are measured at cost at initial recognition. Intangible assets are amortized using the straight-line method over their estimated useful lives. Useful lives of major categories of intangible assets are as follows: Years of useful lives Software 2 – 10 Development costs 2 – 5 The amortization methods, useful lives and residual values are reviewed at the end of each reporting period, and if there are any changes necessary, those changes are applied prospectively as a change in accounting estimate. Expenditures on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset.
Leases	(8) Leases The determination of whether an arrangement is a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains a lease if fulfilment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement. Lessee The Group leases property, plant and equipment and intangible assets as a lessee. The determination of whether an agreement contains a lease is based on the examination of the economic nature of the transactions regardless of the form of the lease. Among the lease transactions, those that substantially transfer all the risks and rewards of ownership to the Group are classified as finance leases, and leases other than finance leases are classified as operating leases. For finance leases, leased assets (presented in the respective accounts of “Property, plant and equipment” or “Intangible assets”) and lease obligations (presented in “Other financial liabilities (current)” and “Other financial liabilities (non-current))” For operating leases, lease payments are recognized as an expense on a straight-line basis over the lease term. Lessor The Group undertakes leasing activities involving property, plant and equipment as a lessor. The determination of whether an agreement contains a lease is based on the examination of the economic nature of the transactions regardless of the form of the lease. For finance leases, net investments in finance leases are recognized as lease receivables (presented in “Trade and other receivables”). Lease receivables are categorized into amounts equivalent to the principal and interest of lease receivables. Further, if the main purpose of a finance lease is the sale of products and the finance leases have been implemented in accordance with sales policies, the lower of the fair value of the assets subject to leases or minimum lease payment receivable discounted at the market rate of interest is recognized as revenue, and the purchase price of the leased assets is recognized in cost of sales. For operating leases, lease income is recognized on a straight line basis over the term of the lease. The respective leased assets are included in the statement of financial position based on their nature.
Impairment of property, plant and equipment, and intangible assets	(9) Impairment of property, plant and equipment, and intangible assets The Company assesses at the end of each reporting period whether there is an indication that an asset may be impaired. If any such indication exists, the Company recognizes impairment losses when its carrying amount exceeds its recoverable amount. The recoverable amount of an asset or CGU is the higher of fair value less costs of disposal and value in use. Value in use is determined as the present value of future cash flows expected to be derived from an asset or CGU. When it is not possible to estimate the recoverable amount of the individual asset, the recoverable amount of CGU to which the asset belongs is estimated. When the carrying amount of CGU exceeds the recoverable amount, the carrying amount is reduced to the recoverable amount and an impairment loss is recognized in profit or loss. An impairment loss for CGU is allocated to the assets on the basis of the relative carrying amount of each asset in the unit. The Group determines at the end of each reporting period whether there is any indication that an impairment loss recognized in prior years has decreased or extinguished. An impairment loss is reversed when there is an indication that there has been a change in the estimates used to determine an asset’s recoverable amount. When an impairment loss recognized is reversed, carrying amount of the asset is increased to its updated estimated recoverable amount. A reversal of an impairment loss is recognized, to the extent the increased carrying amount does not exceed the lower of the recoverable amount or the carrying amount (net of depreciation and amortization) that would have been determined had no impairment loss been recognized. A reversal of an impairment loss is recognized as “Other operating income.”
Financial instruments	(10) Financial instruments The Group applies the requirements for financial instruments under IFRS 9 “Financial Instruments” issued in July 2014. (a) Recognition and derecognition The Group initially recognizes a financial asset or a financial liability when it becomes a party to the contractual provisions of the instrument. The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred, or it neither transfers nor retains substantially all of the risks and rewards of ownership and does not retain control over the transferred asset. Any interest in such derecognized financial assets created or retained by the Group is recognized as a separate asset or liability. The Group derecognizes a financial liability when its contractual obligations are discharged, cancelled, or expire. The Group directly writes off the gross carrying amount of financial assets that are legally discharged (by court or relevant law) or where the Group has no reasonable expectations of recovering a financial asset in question in its entirety or a portion. (b) Offsetting Financial assets and liabilities are offset and the net amount is presented in the statement of financial position when, and only when, the Group has a legally enforceable right to offset the amounts and intends to settle them on a net basis or to realize the asset and settle the liability simultaneously. (c) Classification and measurement—financial assets Financial assets are classified as subsequently measured at amortized cost, fair value through other comprehensive income (“FVOCI”) or fair value through profit or loss (“FVPL”). A regular way purchase or sale of financial assets is recognized and derecognized, as applicable, using transaction date accounting or settlement date accounting. The Group applies the following dates to account for each classification of financial asset: •   Financial assets at amortized cost Settlement date accounting •   Financial assets at FVOCI Transaction date accounting •   Financial assets at FVPL Transaction date accounting (i) Financial assets at amortized cost A financial asset is measured at amortized cost if both of the following conditions are met: • the financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows, and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. These assets are initially measured at fair value plus any directly attributable transaction costs. Subsequent to initial recognition, they are measured at amortized cost using the effective interest method. The impairment requirements discussed below are also applied. (ii) Financial assets at FVOCI A financial asset is measured at FVOCI if both of the following conditions are met: • the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and • the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. (iii) Financial assets at FVPL A financial asset that is not measured at amortized cost or FVOCI is classified as measured at FVPL. It can also be designated as such on initial recognition. Directly attributable transaction costs are recognized in profit or loss as incurred. A gain or loss on a financial asset that is measured at FVPL is recognized in profit or loss. The Group may make an irrevocable election at initial recognition for particular investments in equity instruments that would otherwise be measured at FVPL to present subsequent changes in fair value in other comprehensive income. (iv) Investments in equity instruments designated at FVOCI After initial recognition, investments in equity instruments not held for trading that are designated as measured at FVOCI should be measured at fair value, with no deduction for sale or disposal costs. With the exception of dividends received, the associated gains and losses (including any related foreign exchange component) are recognized in OCI. Amounts presented in OCI are not subsequently reclassified to profit or loss. (d) Classification and measurement—financial liabilities Financial liabilities are classified either as subsequently measured at FVPL or at amortized cost. Financial liabilities are classified as at FVPL if it is classified as held-for-trading Financial liabilities at amortized cost are initially measured at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these liabilities are measured at amortized cost using the effective interest method. (e) Impairment Impairment is based on an expected credit loss (“ECL”) model. The Group applies a three-stage approach to measuring ECL on debt instruments accounted for at amortized cost and FVOCI. Assets migrate through the following three stages based on the change in credit quality since initial recognition: Stage 1: 12-month For exposure on debt instruments where there has not been a significant increase in credit risk since initial recognition and that were not credit impaired upon origination, the portion of the lifetime ECL associated with the probability of default events occurring within the next 12 months is recognized. Stage 2: Lifetime ECL—not credit-impaired For credit exposure on debt instruments where there has been a significant increase in credit risk since initial recognition but that are not credit impaired, a lifetime ECL is recognized. Stage 3: Lifetime ECL—credit-impaired Financial assets are assessed as credit impaired when one or more events that have detrimental impact on the estimated future cash flows of that asset have occurred. For financial assets that have become credit impaired, a lifetime ECL is recognized and interest income is calculated applying the effective interest rate to the amortized cost (net of provision) rather than the gross carrying amount. At each reporting date, the Group assesses whether there has been a significant increase in credit risk for financial assets since initial recognition by comparing the risk of default occurring over the expected life between the reporting date and the date of initial recognition. The indicators used by the Group to assess whether there is any objective evidence of impairment include: significant financial difficulties of the issuer or the borrower; breach of contract, such as default or past due event in interest or principal payment, or; probable event that borrower will enter bankruptcy or financial reorganization. If, in a subsequent period, credit quality improves and reverses any previously assessed significant increase in credit risk since origination, then the provision for doubtful debts reverts from lifetime ECL to 12-month The Group applies the simplified approach for all trade receivables and lease receivables, instead of the three-stages above. Under this approach, the Group does not track changes in credit risk, but instead recognizes loss allowances based on lifetime ECL upon origination and at each reporting date. (f) Derivatives and hedge accounting In order to hedge foreign currency risks, the Group utilizes derivative transactions including foreign exchange forward contracts. At the initiation of a transaction, the Group documents the relationship between the hedging instrument and the hedged item, along with the risk management objective and strategy for undertaking the hedge transaction. Additionally, at the inception of the hedge and on an ongoing basis, the Group assesses whether the derivative designated as hedging instrument meets the criteria for hedge accounting in offsetting changes in cash flows of the hedged item. Derivatives are initially recognized at fair value. For derivatives which do not meet the criteria for hedge accounting, subsequent changes in fair value are recognized in profit or loss. For derivatives which meet the criteria for hedge accounting, changes in fair value of derivatives that are designated and qualify as cash flow hedges are recognized in other comprehensive income. However, the ineffective portion of changes in the fair value of hedging derivatives is recognized in profit or loss. Amounts accumulated in other comprehensive income are reclassified to profit or loss in the period when the hedged item affects profit or loss. However, when the hedged forecast transaction subsequently results in the recognition of a non-financial Furthermore, hedge accounting is discontinued prospectively when cash flow hedges no longer meet the criteria for hedge accounting, or when the hedging instrument expires or is sold, terminated or exercised.
Borrowings	(11) Borrowings Borrowings are initially recognized at fair value, net of transaction costs incurred and measured subsequently at amortized cost. Any difference between the proceeds, net of transaction costs, and the redemption amount is recognized in profit or loss over the period of the borrowings using the effective interest method. Fees paid on the financing of debt facilities are recognized as transaction costs of the debt to the extent that it is probable that some or all of the facility will be drawn down.
Borrowing costs	(12) Borrowing costs Borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized during the period of time that is required to complete and prepare the asset for its intended use. Qualifying assets are assets that necessarily take a substantial period of time to get ready for their intended use. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are expensed in the period in which they are incurred.
Provisions and contingencies	(13) Provisions and contingencies The consolidated financial statements include all provisions for which it is considered more likely than not that the corresponding obligation will have to be settled. Provisions are measured at the present value of the best estimate of the amount required to settle the obligation or transfer it, taking into account the information available on the event and its consequences. Adjustments arising from the discounting of the provision are recognized as finance costs when accrued. Any items of contingent liabilities that may have a material impact on business in the future are disclosed in light of all available evidence at the end of the reporting period and by taking into account the probability of these contingencies and their impact on financial reporting.
Employee benefits	(14) Employee benefits (a) Short-term employee benefits Short-term employee benefits are expensed as the related service is provided. A liability is recognized for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably. (b) Defined contribution plans Obligations for contributions to defined contribution plans are expensed as the related service is provided. (c) Defined benefit plans The Group’s net obligation related to defined benefit plans is calculated separately for each 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. The calculation of defined benefit obligations are performed annually by qualified actuaries using the projected unit credit method. Remeasurements of defined benefit liabilities, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. The Group determines the net interest expense on defined benefit liabilities for the period by applying discount rate used to measure the defined benefit obligations at the beginning of the annual period to the then defined benefit liabilities, taking into account any changes in defined benefit liabilities during the period as a result of contributions and benefit payments. Net interest expense and other operating expenses related to defined benefit plans are recognized in profit or loss. Actuarial gains and losses arising from the defined benefit plan are recognized immediately in other comprehensive income and directly reclassified to retained earnings from other components of equity. When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Group recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs.
Income taxes	(15) Income taxes Income tax expense is comprised of current and deferred taxes, and it is recognized in profit or loss except for taxes arising from business combinations and transactions which are recognized directly in equity or in other comprehensive income. (a) Current tax Current tax is comprised of expected taxes payable or receivable on the taxable income or loss for the year and any adjustment to the taxes payable or receivable in respect of the previous years. The amount of current taxes payable or receivable is the best estimate of the tax amount expected to be paid or received that reflects uncertainty related to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any taxes arising from dividends. Current tax assets and liabilities are offset only if certain criteria are met. (b) Deferred tax Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognized for: • Temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss, and; • Temporary differences related to investments in subsidiaries, associates, and joint ventures to the extent that the Group is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future Deferred tax assets are recognized for unused tax losses, unused tax credits and deductible temporary differences to the extent that it is probable that future taxable profits will be available for utilization. Future taxable profits are estimated based on business plans for the Group. 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. Unrecognized deferred tax assets are reassessed at each reporting date and recognized to the extent that it has become probable that future taxable profits will be available against which they can be used. Deferred tax assets and liabilities are measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date. Deferred tax assets and liabilities are offset only if certain criteria are met.
Equity	(16) Equity (a) Ordinary shares Common shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares are recognized as a deduction from equity, net of any related taxes. (b) Repurchase and sale of ordinary shares (treasury shares) When shares recognized as equity are repurchased, the amount of the consideration paid, which includes directly attributable costs, is recognized as a deduction from equity and presented as treasury shares. When treasury shares are sold subsequently, the consideration received is recognized as an increase in equity and the difference between the consideration received and the carrying amount is recognized in capital surplus.
Dividends	(17) Dividends Dividends to shareholders of the Company are recognized as a liability when such dividends are approved by the shareholders on or before the end of the reporting period but not yet distributed at the end of the reporting period.
Revenue recognition	(18) Revenue recognition The Group adopted the new revenue recognition standard issued by IASB, IFRS 15 “Revenue from Contracts with Customer” from the year beginning on April 1, 2018. Before adoption of IFRS 15, the Group generally recognized revenue from sales of goods upon shipment or delivery, depending on when risk and rewards were transferred to customers. Revenue from rendering of services was recognized by reference to the stage of completion of the service at the end of the reporting period. Revenue was measured at the fair value of the consideration received or receivable, net of returns, trade discounts, volume rebates and consumption taxes. The Group has examined and concluded that the prior methods of revenue recognition and measurement were substantially in accordance with IFRS 15 and therefore no material adjustment was made to the beginning balance of the retained earnings under the modified retrospective method. Details of the revenue recognition policy of the Group are as follows. The Group recognizes revenue by applying the following steps: Step 1: Identify the contracts with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when or as the entity satisfies a performance obligation The Group engages in the manufacturing and selling of products such as electronic components, car navigation and audio systems and other products through the electronic components segment and the automotive infotainment segment. Revenue from sales of these products is recognized upon shipment or delivery, depending on when the control over the products is considered transferred to the customer based on sales agreements. The Group also renders transportation, storage, forwarding services, system development, and other services to its customers through the logistics and other segments. The Group recognizes these revenues over time because its customers simultaneously receive and consume the benefits provided by the Group. The transaction prices that the Group is entitled to receive in exchange for transferring goods and services to the customer include certain forms of variable consideration, including trade discounts and volume rebates provided mainly to automotive makers. The Group includes estimated amounts in the transaction price only to the extent that it is highly probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Variable consideration amounts are estimated based upon historical trends and are subsequently adjusted in each period based on current information available. Transaction consideration is mostly received within three months from the provision of goods and services and therefore does not involve a significant financing component. Consumption taxes collected from customers on behalf of governmental authorities are excluded from revenue. See Note 22 “Revenue” for more information.
Government grants	(19) Government grants Government grants are not recognized until there is reasonable assurance that the Group will comply with the conditions attached to the grants and that the grants will be received. Government grants associated with an expense are recognized as “Other operating income” in the consolidated statements of profit or loss in the same accounting period when the expense is incurred. Government grants for purchase of assets are recognized as “Other current and non-current The Group has been awarded government grants mainly from the Ministry of Economy, Trade and Industry of Japan and Fukushima Prefecture of Japan to subsidize the costs of purchases of equipment and investing in the development of Fukushima Prefecture.
Share-based payments	(20) Share-based payments The Group has granted equity-settled share options to directors. The fair value of share options at the grant date is recognized as expenses over the vesting period from the grant date, with a corresponding increase in equity. The share options vest conditionally on continued employment and are awarded upon approval by the Board of Directors.
