Summary Of Significant Accounting Policies [Abstract]
A1 Significant accounting policies	A1 Basis of presentation Introduction The consolidated financial statements comprise Telefonaktiebolaget LM Ericsson, the Parent Company, and its subsidiaries (“the Company”) and the Company’s interests in joint ventures and associated companies. The Parent Company is domiciled in Sweden at Torshamnsgatan 21, SE-164 83 Stockholm. The consolidated financial statements for the year ended December 31, 2019 have been prepared in accordance with International Financial Reporting Standards (IFRS) as endorsed by the EU and RFR 1 “Additional rules for Group Accounting,” related interpretations issued by the Swedish Financial Reporting Board (Rådet för Finansiell Rapportering), and the Swedish Annual Accounts Act. For the financial reporting of 2019, the Company has applied IFRS as issued by the IASB (IFRS effective as per December 31, 2019). There is no difference between IFRS effective as per December 31, 2019, and IFRS as endorsed by the EU, nor is RFR 1 related interpretations issued by the Swedish Financial Reporting Board (Rådet för Finansiell Rapportering) or the Swedish Annual Accounts Act in conflict with IFRS, for all periods presented. For disclosure about new standards and amendments applied as from January 1, 2019, see note A3, “Changes in accounting policies.” The preparations for the adoption of new standards and interpretations not adopted 2019 are disclosed at the end of this note, see subheading Other. Basis of presentation The financial statements are presented in millions of Swedish Krona (SEK). They are prepared on a historical cost basis, except for certain financial assets and liabilities that are stated at fair value: financial instruments classified as fair value through profit and loss (FVTPL), financial instruments classified as fair value through other comprehensive income (FVOCI) and plan assets related to defined benefit pension plans. Financial information in the consolidated income statement, the consolidated statement of comprehensive income, the consolidated statement of cash flows and the consolidated statement of changes in equity with related notes are presented with two comparison years. For the consolidated balance sheet, financial information with related notes is presented with two comparison year. Basis of consolidation and composition of the Group The consolidated financial statements are prepared in accordance with the purchase method. Accordingly, consolidated stockholders’ equity includes equity in subsidiaries, joint ventures and associated companies earned only after their acquisition. Subsidiaries are all companies for which Telefonaktiebolaget LM Ericsson, directly or indirectly, is the parent. To be classified as a parent, Telefonaktiebolaget LM Ericsson, directly or indirectly, must control another company which requires that the Parent Company has power over that other company, is exposed to variable returns from its involvement and has the ability to use its power over that other company. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that such control ceases. Intra-group balances and any unrealized income and expense arising from intra-group transactions are fully eliminated in preparing the consolidated financial statements. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. The Company is composed of a parent company, Telefonaktiebolaget LM Ericsson, with generally fully-owned subsidiaries in many countries of the world. The largest operating subsidiaries are the fully-owned telecom vendor companies Ericsson AB, incorporated in Sweden and Ericsson Inc., incorporated in the US. Foreign currency remeasurement and translation Items included in the financial statements of each entity of the Company are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in Swedish Krona (SEK), which is the Parent Company’s functional and presentation currency. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of each respective transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement. Changes in the fair value of monetary securities denominated in foreign currency classified as fair value through other comprehensive income (FVOCI) are allocated between translation differences resulting from changes in the amortized cost of the security and other changes in the carrying amount of the security. Translation differences related to changes in the amortized cost are recognized in profit or loss, and other changes in the carrying amount are recognized in Other Comprehensive Income (OCI). Translation differences on monetary financial assets and liabilities are reported as part of the fair value gain or loss. From 2019, in order to reflect the way the Company manages its foreign exchange risks on a net basis, foreign exchange effect is presented as a net item within Financial Income and Expenses, reported separately from other financial income and expenses items. Previously foreign exchange effects were reported within both Financial Income and Financial Expense depending on whether they were related to assets or liabilities. Note F2, “Financial income and expenses” has been restated to reflect the change. Group companies The results and financial position of all the group entities that have a functional currency different from the presentation currency are translated into the presentation currency as follows: Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet. Period income and expenses for each income statement are translated at period average exchange rates. All resulting net exchange differences are recognized as a separate component of Other comprehensive income (OCI). On consolidation, exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are accounted for in OCI. When a foreign operation is disposed of or sold, exchange differences that were recorded in OCI are recognized in the income statement as part of the gain or loss on sale. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and are translated at the closing rate. The Company is continuously monitoring the economies with high inflation, the risk of hyperinflation and potential impact on the Company. There is no significant impact due to any currency translation of a hyper-inflationary economy. Business and operations For further disclosure, see the notes under section B Revenue recognition IFRS 15, “Revenue from Contracts with Customers” is a principle-based model of recognizing revenue from customer contracts. It has a five-step model that requires revenue to be recognized when control over goods and services are transferred to the customer. The following paragraphs describes the types of contracts, when performance obligations are satisfied, and the timing of revenue recognition. They also describe the normal payment terms associated with such contracts and the resulting impact on the balance sheet over the duration of the contracts. The vast majority of Ericsson’s business is for the sale of standard products and services. Standard products and services Products and services are classified as standard solutions if they do not require significant installation and integration services to be delivered. Installation and integration services are generally completed within a short period of time, from the delivery of the related products. These products and services are viewed as separate distinct performance obligations. This type of customer contract is usually signed as a frame agreement and the customer issues individual purchase orders to commit to purchases of products and services over the duration of the agreement. Note A1, cont’d. Revenue for standard products is recognized when control over the equipment is transferred to the customer at a point in time. This assessment shall be viewed from a customer’s perspective considering indicators such as transfer of titles and risks, customer acceptance, physical possession, and billing rights. For hardware sales, transfer of control is usually deemed to occur when the equipment arrives at the customer site and for software sales, when the licenses are made available to the customer. Software licenses may be provided to the customer at a point in time, activated or ready to be activated by the customer at a later stage, therefore revenue is recognized when customer obtains control of the software. Contractual terms may vary, therefore judgment will be applied when assessing the indicators of transfer of control for both hardware and software sales. Software licenses are also sold on a when-and-if available basis or delivered to the customer network over a period of time. In such cases, the customer is billed on a subscription basis or based on usage, and revenue is recognized over time. Revenue for installation and integration services is recognized upon completion of the service. Costs incurred in delivering standard products and services are recognized as costs of sales when the related revenue is recognized in the Income statement. Costs incurred relating to performance obligations not yet fully delivered are recognized as Inventories. Transaction prices under these contracts are usually fixed, and mostly billed upon delivery of the hardware or software, or completion of installation services. A proportion of the transaction price may be billed upon formal acceptance of the related installation services, which will result in a contract asset for the proportion of the transaction price that is not yet billed. Amounts billed are normally subject to payments terms within 60 days from invoice date. Customer finance agreements may be agreed separately with some customers where payment terms exceed 179 days. Revenue for recurring services such as customer support and managed services is recognized as the services are delivered, generally pro-rata over time. Costs incurred in delivering recurring services are recognized as cost of sales as they are incurred. Transaction prices under these contracts are billed over time, often on a quarterly basis. Transaction price for managed services contract may include variable consideration that is estimated based on performance and prior experience with the customer. Amounts billed are normally subject to payments terms within 60 days from invoice date. Contract liabilities or receivables may arise depending on whether the quarterly billing is in advance or in arrears. Contracts for standard products and services apply to business in all segments. Customized solution Some products and services are sold together as part of a customized solution to the customer. This type of contract requires significant installation and integration services to be delivered within the solution, normally over a period of more than one year. These products and services are viewed together as a combined performance obligation. This type of contract is usually sold as a firm contract in which the scope of the solution and obligations of both parties are clearly defined for the duration of the contract. Customized solution does not have any alternative use to the Company as it cannot be sold to or used by other customers. Revenue for the combined performance obligation shall be recognized over time if progress of completion can be reliably measured and enforceable right to payment exists over the duration of the contract. The progress of completion is estimated by reference to the output delivered such as achievement of contract milestones and customer acceptance. This method determines revenue milestones over the duration of the contract, and it is considered appropriate as it reflects the nature of the customized solution and how integration service is delivered in these projects. If the criteria above are not met, then all revenue shall be recognized upon the completion of the customized solution, when final acceptance is provided by the customer. Costs incurred in delivering customized solutions are recognized as costs of sales when the related revenue milestone is recognized in the Income statement. Costs incurred relating to future revenue milestones are recognized as Inventories and assessed for recoverability on a regular basis. Transaction price under these contracts is usually a fixed fee, split into a number of progress payments or billing milestones as defined in the contract. In most cases, revenue recognized is limited to the progress payments or unconditional billing milestones over the duration of the contract, therefore no contract asset or contract liability arises on these contracts. In some contracts, revenue may be recognized in advance of billing milestones if enforceable payment rights exist at all times over the contract duration. This will result in an unbilled receivable balance until billing milestones are reached. Amounts billed are normally subject to payments terms within 60 days from invoice date. Customer finance agreements may be agreed separately with some customers where payment terms exceed 179 days. Contract for customized solution applies to the Business Support Systems (BSS) business within the segment Digital Services. Intellectual Property Rights (IPR) This type of contract relates to the patent and licensing business. The Company has assessed that the nature of its IPR contracts is such that they provide customers a license with the right to access the Company intellectual properties over time, therefore revenue shall be recognized over the duration of the contract. Royalty revenue based on sales or usage is recognized when the sales and usage occur. The transaction price on these contracts is usually structured as a royalty fee based on sales or usage over the period, measured on a quarterly basis. This results in a receivable balance if the billing is performed the following quarter after measurement. Some contracts include lump sum amounts, payable either up front at commencement or on an annual basis. This results in a contract liability balance if payment is in advance of revenue, as revenue is recognized over time. Amounts billed are normally subject to payments terms within 60 days from invoice date. As described in note B1 “Segment Information”, revenue from IPR licensing contracts are allocated to the segments Networks and Digital Services. Customer contract related balances Trade receivables include amounts that have been billed in accordance with customer contract terms and amounts that the Company has an unconditional right to, with only passage of time before the amounts can be billed in accordance with the customer contract terms. Customer finance credits arise from credit terms exceeding 179 days in the customer contract or a separate financing agreement signed with the customer. Customer finance is a class of financial assets that is managed separately from receivables. See note F1, “Financial risk management,” for further information on credit risk management of trade receivables and customer finance credits. In accordance with IFRS 15, where significant financing is provided to the customer, revenue is adjusted to reflect the impact of the financing transaction. These transactions could arise from the customer finance credits above if the contracted interest rate is below the market rate or through implied financing transactions due to payment terms of more than one year from the date of transfer of control. The Company has elected to use the practical expedient not to adjust revenue for transactions with payment terms, measured from the date of transfer of control, of one year or less. Contract asset is unbilled sales amount relating to performance obligation that has been satisfied under customer contract but is conditional on terms other than only the passage of time before payment of the consideration is due. Under previous standards these unbilled sales balances have been included within trade receivables. Contract liability relates to amounts that are paid by or due from customers for which performance obligations are unsatisfied or partially satisfied. Under previous standards these balances have been disclosed as deferred revenue within other current liabilities, and the Company concluded that the balances meet the definition of contract liability under IFRS 15. Advances from customers are also included in the contract liability balance. Segment reporting An operating segment is a component of a company whose operating results are regularly reviewed by the Company’s chief operating decision maker, (CODM), to make decisions about resources to be allocated to the segment and assess its performance. The President and the CEO is defined as the CODM function in the Company. The segment presentation, as per each segment, is based on the Company’s accounting policies as disclosed in this note. The Company’s segment disclosure about geographical areas is based on the country in which transfer of risks and rewards occur. For further information, see note B1, “Segment information.” Inventories Inventories are measured at the lower of cost or net realizable value on a first-in, first-out (FIFO) basis. Risks of obsolescence have been measured by estimating market value based on future customer demand and changes in technology and customer acceptance of new products. A significant part of Inventories is Contract work in progress (CWIP). Recognition and derecognition of CWIP relates to the Company’s revenue recognition principles meaning that costs incurred under a customer contract are initially recognized as CWIP (see Revenue recognition policy). When the related revenue is recognized, CWIP is derecognized and is instead recognized as Cost of sales. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied. Note A1, cont’d. Trade payables See accounting policies under the subheading for Financial instruments and risk management. Long-term assets For further disclosure, see the notes under section C Goodwill As from the acquisition date, goodwill acquired in a business combination is allocated to each cash-generating unit (CGU) of the Company expected to benefit from the synergies of the combination. An annual impairment test for the CGUs to which goodwill has been allocated is performed in the fourth quarter, or when there is an indication of impairment. An impairment loss is recognized if the carrying amount of an asset or its cash-generating unit exceeds its recoverable amount. The recoverable amount is the higher of the value in use and the fair value less costs of disposal. In assessing value in use, the estimated future cash flows after tax are discounted to their present value using an after-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Application of after-tax amounts in calculation, both in relation to cash flows and discount rate is applied due to that available models for calculating discount rate include a tax component. The after-tax discount rate applied by the Company is not materially different from a discounting based on before-tax future cash flows and before-tax discount rates, as required by IFRS. An impairment loss in respect of goodwill is not reversed. Write-downs of goodwill are reported under other operating expenses. As a result of the application of IFRS 16 the impairment test has been modified to include also right-of-use assets in the carrying value but not lease liabilities. Additional disclosure is required in relation to goodwill impairment testing: see note A2, “Critical accounting estimates and judgments” below and note C1, “Intangible assets.” Intangible assets and other than goodwill Intangible assets other than goodwill comprise intangible assets acquired through business combinations, such as patents, customer relations, trademarks and software, as well as capitalized development expenses and separately acquired intangible assets, mainly consisting of software. At initial recognition, acquired intangible assets related to business combinations are stated at fair value and capitalized development expenses and software are stated at cost. Subsequent to initial recognition, these intangible assets are stated at initially recognized amounts less accumulated amortization and any impairment. Amortization and any impairment losses are included in Research and development expenses, which mainly consists of capitalized development expenses and technology; in Selling and administrative expenses, which mainly consists of expenses relating to customer relations and brands; and in Cost of sales. Costs incurred for development of products to be sold, leased, or otherwise marketed or intended for internal use are capitalized as from when technological and economic feasibility has been established until the product is available for sale or use. Research and development expenses directly related to orders from customers are accounted for as a part of Cost of sales. Other research and development expenses are charged to income as incurred. Amortization of acquired intangible assets, such as patents, customer relations, trademarks, and software, is made according to the straight-line method over their estimated useful lives, not exceeding ten years. The Company has not recognized any intangible assets with indefinite useful life other than goodwill. Impairment tests are performed whenever there is an indication of impairment. Tests are performed in the same way as for goodwill, see above. However, intangible assets not yet available for use are tested annually. Corporate assets have been allocated to cash-generating units in relation to each unit’s proportion of total net sales. The amount related to corporate assets is not significant. Impairment losses recognized in prior periods are assessed at each reporting date for any indications that the loss has decreased or no longer exists. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied. Property, plant, and equipment Property, plant, and equipment consist of real estate, machinery, servers and other technical assets, other equipment, tools and installation and construction in process. They are stated at cost less accumulated depreciation and any impairment losses. Depreciation is charged to income, on a straight-line basis, over the estimated useful life of each component of an item of property, plant, and equipment, including buildings. Estimated useful lives are, in general, 25–50 years for real estate and 3–10 years for machinery and equipment. Depreciation and any impairment charges are included in Cost of sales, Research and development or Selling and administrative expenses. The Company recognizes in the carrying amount of an item of property, plant, and equipment the cost of replacing a component and derecognizes the residual value of the replaced component. Impairment testing as well as recognition or reversal of impairment of property, plant and equipment is performed in the same manner as for intangible assets other than goodwill, see description under “Intangible assets other than goodwill” above. Gains and losses on disposals are determined by comparing the proceeds less cost to sell with the carrying amount and are recognized within Other operating income and expenses in the income statement. Leasing The main types of assets leased by the Company are, in the order of materiality, real estate, IT-equipment and vehicles. Vehicles are mainly used under service contracts. Accounting policies applied as of January 2019 - IFRS 16 Leases Leasing when the Company is the lessee The Company recognizes right-of-use assets and lease liabilities arising from all leases in the balance sheet, with some exceptions. This model reflects that, at the start of a lease, the lessee always obtains the right to use an asset for a period of time and has an obligation to pay for that right. In the assessment of a lease contract the lease components are separated from non-lease components and the lease term is defined based on the contract lease term and when reasonably certain estimated extension or termination options are included. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted normally using the Company’s incremental borrowing rate. The incremental borrowing rate is calculated considering interest swap rates, the credit spread on bonds issued by real estate companies and the creditworthiness of the entity that signs the lease. Lease payments included in the liability are fixed payments, variable payments depending on an index or rate, residual values and penalties for termination of contracts. The right-of-use asset is initially measured at cost, which equals the amount of the initial measurement of lease liability adjusted for any lease payments made at or before the commencement date less any lease incentives received plus any initial direct costs, and restoration costs. The Company applies the recognition exemption for short-term leases and leases for which the underlying asset is of low-value recognizing the lease payments for those leases as an expense on a straight-line basis over the lease term. The interest expense on lease liabilities is presented as a component of finance costs separate from the depreciation charges for right-of-use assets. In the statement of cash flows, cash payments for the principal portion of the lease liability is reported within financing activities while payments for short-term leases, low-value assets and variable lease expenses not included in the measurement of the lease liability are classified within operating activities. For more information regarding leasing see note C3, “Leases.” Leasing when the Company is the lessor Leasing contracts with the Company as lessor are classified as finance leases when the majority of risks and rewards are transferred to the lessee, and otherwise as operating leases. Under a finance lease, a receivable is recognized at an amount equal to the net investment in the lease and revenue is recognized in accordance with the revenue recognition principles. Under operating leases the equipment is recorded as property, plant and equipment and revenue as well as depreciation is recognized on a straight-line basis over the lease term. Accounting policies applied prior to 2019 Prior to 2019, IAS 17 was applied instead of IFRS 16. Comparative information has not been restated. The following accounting policies apply to periods prior to 2019. Leasing when the company was the lessee Leases on terms in which the Company assumed substantially all the risks and rewards of ownership were classified as finance leases. Upon initial recognition, the leased asset was measured at an amount equal to the lower of its fair value and the present value of the minimum lease payments. Subsequent to initial recognition, the asset was accounted for in accordance with the accounting policy applicable to that type of asset, although the depreciation period did not exceed the lease term. Note A1, cont’d. Other leases were operating leases, and the leased assets under such contracts were not recognized on the balance sheet. Costs under operating leases were recognized in the income statement on a straight-line basis over the term of the lease. Lease incentives received were recognized as an integral part of the total lease expense, over the term of the lease. Leasing when the Company was the lessor Leasing contracts with the Company as lessor were classified as finance leases when the majority of risks and rewards were transferred to the lessee, and otherwise as operating leases. Under a finance lease, a receivable was recognized at an amount equal to the net investment in the lease and revenue was recognized in accordance with the revenue recognition principles. Under operating leases the equipment was recorded as property, plant and equipment and revenue as well as depreciation was recognized on a straight-line basis over the lease term. Obligations For further disclosure, see the notes under section D Provisions Provisions are made when there are legal or constructive obligations as a result of past events and when it is probable that an outflow of resources will be required to settle the obligations and the amounts can be reliably estimated. When the effect of the time value of money is material, discounting is made of estimated outflows. However, the actual outflows as a result of the obligations may differ from such estimates. The provisions are mainly related to restructuring, customer and supplier related provisions, warranty commitments and other obligations, claims or obligations as a result of patent infringement and other litigations and customer finance guarantees. Product warranty commitments consider probabilities of all material quality issues based on historical performance for established products and expected performance for new products, estimates of repair cost per unit, and volumes sold still under warranty up to the reporting date. A restructuring obligation is considered to have arisen when the Company has a detailed formal plan for the restructuring (approved by management), which has been communicated in such a way that a valid expectation has been raised among those affected. Provision for restructuring is recorded when the Company can reliably estimate the liabilities relating to the obligation. Customer contract provisions mainly consist of estimated losses on onerous contracts. For losses on customer contracts, a provision equal to the total estimated loss is recorded immediately when a loss from a contract is probable and can be estimated reliably. These contract loss estimates may include penalties under a loss contract. Other provisions include provisions for obligations related to cash-settled share-based programs, litigations and other provisions. The Company provides for estimated future settlements related to patent infringements based on the probable outcome of each infringement. The actual outcome or actual cost of settling an individual infringement may vary from the Company’s estimate. The Company estimates the outcome of any potential patent infringement made known to the Company through assertion and through the Company’s own monitoring of patent-related cases in the relevant legal systems. To the extent that the Company makes the judgment that an identified potential infringement will more likely than not result in an outflow of resources, the Company records a provision based on the Company’s best estimate of the expenditure required to settle with the counterpart. In the ordinary course of business, the Company is subject to proceedings, lawsuits and other unresolved claims, including proceedings under laws and government regulations and other matters. These matters are often resolved over a long period of time. The Company regularly assesses the likelihood of any adverse judgments in or outcomes of these matters, as well as potential ranges of possible losses. Provisions are recognized when it is probable that an obligation has arisen and the amount can be reasonably estimated based on a detailed analysis of each individual issue. Contingent liabilities Certain present obligations are not recognized as provisions as it is not probable that an economic outflow will be required to settle the obligations or the amount of the obligation cannot be measured with sufficient reliability. Such obligations are reported as contingent liabilities. For further detailed information, see note D2, “Contingent liabilities.” In note A2, “

Disclosure Of Accounting Judgements And Estimates [Abstract]
A2 Critical accounting estimates and judgments	A2 The preparation of financial statements and application of accounting standards often involve management’s judgment and the use of estimates and assumptions deemed to be reasonable at the time they are made. However, other results may be derived with different judgments or using different assumptions or estimates, and events may occur that could require a material adjustment to the carrying amount of the asset or liability affected. Examples of this could occur at change of strategy or restructuring. Judgments for accounting policies to be applied as well as estimates may also be impacted due to this. Following are the most important accounting policies subject to such judgments and the key sources of estimation uncertainty that the Company believes could have the most significant impact on the reported results and financial position. The information in this note is grouped as per: – Key sources of estimation uncertainty – Judgments management has made in the process of applying the Company’s accounting policies. Revenue recognition Key sources of estimation uncertainty The Company uses estimates and judgments in determining the amount and timing of revenue under IFRS 15, “Revenue from Contracts with Customers,” particularly when determining the transaction price and its allocation to performance obligations identified under the contract. Transaction price may consist of variable elements such as discounts, performance related price and contract penalties. Transaction price, including variable considerations, is estimated at the commencement of the contract (and periodically thereafter). Judgment is used in the estimation process based on historical experience with the type of business and customer. IFRS 15 also requires revenue to be allocated to each performance obligations by reference to their standalone selling prices. The Company considers that an adjusted market assessment approach should be used to estimate stand-alone selling prices for its products and services for the purposes of allocating transaction price. These estimates are comprised of prices set for similar customer and circumstances, adjusted to reflect appropriate profit margins for the market. Estimates are used to determine discounts that relate specifically to each performance obligations, thus impacting their stand-alone selling prices. Note A2, cont’d. Judgments made in relation to accounting policies applied Management applies judgment when assessing the customer’s ability and intention to pay in a contract. The assessment is based on the latest customer credit standing and the customer’s past payment history. This assessment may change during the contract execution, and if there is evidence of deterioration in the customer’s ability or intention to pay, then under IFRS 15 no further revenue shall be recognized until the collectability criteria is met. Conversely, this assessment may also change favorably over time, upon which revenue shall now be recognized on a contract that did not initially meet the collectability criteria. Revenue for standard products shall be recognized when control over the equipment is transferred to the customer at a point in time. This assessment shall be viewed from a customer’s perspective considering indicators such as transfer of titles and risks, customer acceptance, physical possession, and billing rights. Judgment may be applied in determining whether risk and rewards have been transferred to the customer and whether the customer has accepted the products. In a sale of software license, judgment may also be applied to determine when the software is made available to the customer by considering when they can direct the use of, and obtain substantially all the benefits of, the license. Often all indicators of transfer of control are assessed together and an overall judgment formed as to when transfer of control has occurred in a customer contract. Revenue for customized solutions shall be recognized over time if progress of completion can be reliably measured and enforceable right to payment exists over the duration of the contract. The progress of completion is estimated by reference to the output delivered such as achievement of contract milestones and customer acceptance. Judgment are applied when determining the appropriate revenue milestones that best reflect the progress of completion and are aligned with key acceptance stages within the contract. Customer contract related balances Key sources of estimation uncertainty The Company monitors the financial stability of its customers, the environments in which they operate and historical credit losses. Customer financing assets are valued at fair value on an individual basis. When market pricing is not available, an internal valuation model is applied considering external credit rating, political and commercial risks and bank pricing. Regular monitoring of customer behavior is also a part of the internal assessment. In 2017, as part of the impairment assessment on receivables, the Company also monitored the financial stability of its customers and the environment in which they operate to make estimates regarding the likelihood that the individual receivables will be paid. Allowances are recorded for estimated losses on each individual receivable Inventory valuation Key sources of estimation uncertainty Inventories are valued at the lower of cost and net realizable value. Estimates are required in relation to forecasted sales volumes and inventory balances. In situations where excess inventory balances are identified, estimates of net realizable values for the excess volumes are made. Inventory allowances for estimated losses as of December 31, 2019, amounted to SEK 3.4 (2.6) billion or 10% (8%) of gross inventory. For further detailed information, see note B5, “Inventories.” Acquired intellectual property rights and other Key sources of estimation uncertainty At initial recognition, future cash flows are estimated, to ensure that the initial carrying values do not exceed the expected discounted cash flows for the items of this type of assets. After initial recognition, impairment testing is performed whenever there is an indication of impairment, in addition goodwill impairment testing is performed once per year. Negative deviations in actual cash flows compared to estimated cash flows as well as new estimates that indicate lower future cash flows might result in recognition of impairment charges. Write-downs for intangible assets and goodwill amounted to SEK 0.0 (0.5) billion for 2019. For 2017 impairment charges of SEK 17.2 billion were recognized. At December 31, 2019, the amount of acquired intellectual property rights and other intangible assets amounted to SEK 33.7 (33.5) billion, including goodwill of SEK 31.2 (30.0) billion. For further discussion on goodwill, see note A1, “Significant accounting policies”. Estimates related to acquired intangible assets are based on similar assumptions and risks as for goodwill. For more information, see note C1, “Intangible assets.” Judgments made in relation to accounting policies applied At initial recognition and subsequent remeasurement, management judgments are made, both for key assumptions and regarding impairment indicators. In the purchase price allocation made for each acquisition, the purchase price is assigned to the identifiable assets, liabilities and contingent liabilities based on fair values for these assets. Any remaining excess value is reported as goodwill. This allocation requires management judgment as well as the definition of cash-generating units for impairment testing purposes. Other judgments might result in significantly different results and financial position in the future. Leases Key sources of estimation uncertainty At initial recognition and subsequent remeasurement, management estimates are made for the term applied in a lease contract. The outcome of these estimates may turn out not to match the actual outcome of the lease and may have an adverse effect on the right-of-use assets. Judgments made in relation to accounting policies applied Lease contracts may give the lessee the right to shorten or prolong a contract.Under such contracts management judgement of the lease term is required Provisions Key sources of estimation uncertainty Provisions are mainly related to estimates for onerous contracts with customers and suppliers. Onerous customer contract provision includes estimate of costs to be incurred based on the latest conditions and progress on the contract. Assumptions on the probable outcomes of revenue and costs, which may include costs of potential compensation or penalties on exit, are revised regularly based on latest available information and the provision remeasured accordingly. Other sources for estimation uncertainty are restructuring program execution, patent and other litigations. As commented above in the initial part of this note the amounts may come to differ due to future reassessments and outcomes. As disclosed in note D1, “Provisions” provisions have been recognized due to significant changes during 2018 and 2017 in the accounting estimates for customer contracts resulting from identification of onerous contracts. At December 31, 2019, provisions amounted to SEK 10.9 (16.0) billion. For further detailed information, see note D1, “Provisions.” Judgments made in relation to accounting policies applied Whether a present obligation is probable or not requires judgment. The nature and type of risks for these provisions differ and management’s judgment is applied regarding the nature and extent of obligations in deciding if an outflow of resources is probable or not. Contingent liabilities Key sources of estimation uncertainty As disclosed under ‘Provisions’ there are uncertainties in the estimated amounts. The same type of uncertainty exists for contingent liabilities. Judgments made in relation to accounting policies applied As disclosed under note A1, “Significant accounting policies” a potential obligation that is not likely to result in an economic outflow is classified as a contingent liability, with no impact on the Company’s financial statements. However, should an obligation in a later period be deemed to be probable, then a provision shall be recognized, impacting the financial statements. Foreign exchange risks Key sources of estimation uncertainty Foreign exchange risk impacts the financial results of the Company, see further disclosure in note F1, “Financial risk management,” under Foreign exchange risk. Note A2, cont’d. Pensions and other post-employment benefits Key sources of estimation uncertainty Accounting for the costs of defined benefit pension plans and other applicable post-employment benefits is based on actuarial valuations, relying on key estimates for discount rates, future salary increases, employee turnover rates and mortality tables. The discount rate assumptions are based on rates for high-quality fixed-income investments with durations as close as possible to the Company’s pension plans. In countries where there is not a deep market in high-quality corporate bonds, the market yields on government bonds shall be applied. Judgment is applied in determining the deepness of the high-quality corporate bond market in each country. The impact of applying an alternative discount rate based on Swedish covered bonds is disclosed in note G1, “Post-employment benefits.” At December 31, 2019, defined benefit obligations for pensions and other post-employment benefits amounted to SEK 102.4 (90.3) billion and fair value of plan assets to SEK 69.7 (64.3) billion. For more information on estimates and assumptions, see note G1, “Post-employment benefits.” Deferred taxes Key sources of estimation uncertainty Deferred tax assets and liabilities are recognized for temporary differences and for tax loss carry-forwards. Deferred tax is recognized net of valuation allowances. The valuation of temporary differences and tax loss carry-forwards is based on management’s estimates of future taxable profits in different tax jurisdictions against which the temporary differences and loss carry-forwards may be utilized. These estimates are primarily based on business plans for the Company´s estimated outcome of deductibility in relation to larger provisions. As prescribed in IFRIC 23 estimates are made in relation to uncertain tax positions in a limited number of countries. Estimates are made for any expected changes in tax legislation with a potential material impact. The largest amounts of tax loss carry-forwards are reported in Sweden, with an indefinite period of utilization (i.e. with no expiry date), except for withholding taxes that expire after five years. For further information, see note H1, “Taxes.” At December 31, 2019, the value of deferred tax assets amounted to SEK 31.2 (23.2) billion. The deferred tax assets related to loss carry-forwards are reported as non-current assets . Accounting for income tax, value added tax, and other taxes Key sources of estimation uncertainty Accounting for these items is based upon evaluation of income, value added and other tax rules in all jurisdictions where the Company performs activities. The total complexity of rules related to taxes and the accounting for these require management’s involvement in judgments regarding classification of transactions and in estimates of probable outcomes of claimed deductions and/or disputes.

Summary Of Significant Changes In Accounting Policies [Abstract]
A3 Changes in accounting policies	A3 One new IFRS standard is effective as from January 1, 2019, IFRS 16 “Leases” and one new interpretation IFRIC 23 “Uncertainty over income tax treatments” are effective as from January 1, 2019. IFRIC 23, has not had a material impact on the Company’s financial statements. IFRS 16 – Leases Presentation in the financial statements The Company has implemented this standard using the cumulative catch-up method, which means that the prior periods financial statements and key ratios presented in this annual report have not been restated to reflect adoption of this new standard. Based on the new requirements under IFRS 16, right-of-use assets and lease liabilities have been added as new lines in the consolidated balance sheet and repayment of lease liabilities as a new line in the statement of cash flows. The right-of-use assets and liabilities were prior to 2019 reported as off-balance and repayment to lessors was reported as a part of cash flow from operating activities. Now the amortization of lease liabilities is reported as cash flow from financing activities. Interest expense on the lease liability is reported separately from the depreciation charge for the right-of-use assets. Interest expense on the lease liability is reported as component of finance costs. Transition The standard is effective for annual periods beginning on or after January 1, 2019. The Company has applied the new standard as from January 1, 2019. At transition, the Company has applied the practical expedient under IFRS 16 to not reassess whether a contract is, or contains, a lease. Therefore, the Company has applied the standard to contracts previously identified as leases, or as containing a lease under IAS 17 and IFRIC 4. The Company has also applied the following practical expedients when applying IFRS 16 at transition date: – The IAS 37 onerous lease contract measurement for the operating leases existing as per the transition date. This expedient has been applied as a substitute for the measurement of impairment for the related right-of-use assets. Impairment testing will be applied going-forward. – Exclusion of initial direct costs from the measurement of the right-to-use asset at the date of initial recognition. The Company has implemented the standard using the cumulative catch-up method, with the cumulative effect being adjusted to the opening retained earnings balance in equity at transition date. No restated information has been presented for previous years. The Company has, as a lessee, recognized lease liabilities for leases previously classified as operating leases. The weighted average incremental borrowing rate applied to lease liabilities recognized in the balance sheet at the transition date was 5.4%. Right-of-use assets have for most contracts been recognized based on the amount equal to the related lease liability. For some larger real estate contracts right-of-use assets have been recognized as if IFRS 16 had been applied since the commencement date, however, using the incremental borrowing rate as per the effective date. The asset value for these contracts is SEK 0.2 billion lower than the related liabilities. This difference caused a reduction of equity as per transition date. Under IAS 17 operating leases were not recognized in the balance sheet of a lessee. Future undiscounted minimum lease payments obligations were however disclosed in a note, see note C3 “Leases” in the annual report of 2018, amounting to SEK 13.4 billion. To arrive at the opening discounted lease liability of SEK 10.4 billion the following adjustments were made: – Discounting effect of the lease liability recognized in the statement of financial position at the date of initial application using the weighted average incremental borrowing rate of 5.4% minus SEK 2.1 billion. – Low-value lease agreements which are expensed straight-line minus SEK 0.9 billion – Other adjustments mainly consisting of advance payments, lease term extensions and lease payments corrections. The net impact is zero. Opening balance sheet impact of IFRS 16 IFRS 16 adjustments Right-of-use assets 8,651 Lease liabilities, current 2,195 Lease liabilities, non-current 8,203 Equity 249 In the transition the following items have been considered reducing the value of the lease liabilities: – Advance payments with SEK 0.3 billion In the transition the following items have been considered reducing the value of the right-of-use assets: – Impairment of right-of-use assets with SEK 0.8 billion – Straight-lining, periodization of lease costs, with SEK 0.7 billion – Financial sublease with SEK 0.3 billion. The tax effect on the equity posting is deemed to be immaterial. There is no impact on the income statement. The impact of right-of-use assets increased the total asset value by approximately 3%. Note A3, cont’d. IFRIC 23 – Uncertainty over income tax treatment IFRIC 23 prescribes how an entity shall consider how it prepares its income tax filings and supports tax treatments or how the entity expects the taxation authority to make its examination and resolve issues. In summary, this interpretation clarifies how key parameters under IAS 12 “Income taxes,” as for example taxable profit and unused tax losses, shall be recognized and measured. Restatement – changes to the presentation of financial income and expenses Due to the significant variations in SEK exchange rates during the year, the Company has considered the change in reporting of foreign exchange effect to reflect how foreign exchange transaction risk is managed on a net basis in the Company. Previously foreign exchange effects were reported within both financial income and financial expenses depending on whether they relate to assets or liabilities. In note F2, “Financial income and expenses,” the foreign exchange effect is now presented as a net amount, reported separately from other financial income and expenses items. The comparative years 2018 and 2017 have been restated to reflect the new presentation of Financial income and expenses, net. The restatement does not impact the total net financial income and expenses reported in prior years. The following table shows the impact of the restatement: Financial income and expenses SEK million 2018 2017 Reported in prior years Financial income (316) (372) Financial expenses (2,389) (843) Total (2,705) (1,215) SEK million 2018 2017 Restated Financial income 151 (50) Financial expenses (2,032) (1,570) Net foreign exchange gains and losses (824) 405 Total (2,705) (1,215) In line with this change the Company also elected to present all financial income and expenses, including the foreign exchange effect, on the income statement as a single line item Financial income and expenses, net. Previously, financial income and financial expenses were presented as separate line items on the income statement. The income statement for all comparative years 2018 and 2017 have been restated to reflect the new presentation of Financial income and expenses, net.

Write-down during 2019 In Digital Services and Networks there was an impairment write-down of SEK 0.04 billion related to capitalized development expenses triggered by a change in the GIC program, which is reported on line item Research and development expenses. In segment Emerging Business and Other there was a write-down of SEK 0.02 billion triggered by a change in business strategy, which is reported on line item Selling and administrative expenses. Write-down during 2018 and 2017 In 2018 in Digital Services there was an impairment write-down of SEK 0.3 billion related to capitalized development expenses triggered by a change in the Business Support System (BSS) strategy, which is reported on line item Research and development expenses. In segment Emerging Business and Other for the Cash Generating Unit, CGU, Edge Gravity there was a goodwill impairment write-down of SEK 0.3 billion triggered by a change in business strategy, which is reported on line item Other operating expenses. There is no remaining goodwill for this CGU. In 2017 the following write-downs of goodwill was made: segment Digital Services of SEK 6.9 billion and segment Emerging Business and Other SEK 6.1 billion (of which SEK 6.0 billion related to Media Solutions). These amounts were reported on line item Other operating expenses. In addition to goodwill, write-downs of intangibles and capitalized development expenses was made by SEK 4.2 billion. These amounts were reported on line items Research and development expenses SEK 2.6 billion and Selling and administrative expenses SEK 1.6 billion Goodwill allocation The goodwill allocation has not changed since last year. Goodwill from acquisitions during the year has been allocated to segment Emerging Business and Other. Impairment tests Each operating segment is a CGU, except for segment Emerging Business and Other which consists of four CGUs. The value in use method has been used for goodwill impairment testing for all CGUs, which means that the recoverable amounts for CGUs are established as the present value of expected future cash flows based on five-year business plans approved by management. Estimation of future cash flows includes assumptions mainly for the following key financial parameters: – Sales growth – Development of operating income (based on operating margin or cost of goods sold and operating expenses relative to sales) – Related development of working capital and capital expenditure requirements. The assumptions regarding industry-specific market drivers and market growth are based on industry sources as input to the projections, 2020–2024, made within the Company for the development for key industry parameters: – By 2024, less than 35 years after the introduction of digital mobile technology, it is predicted that there will be 8.8 billion mobile subscriptions. – The number of mobile subscriptions is estimated to grow from around 8.0 billion by the end of 2019 to around 8.8 billion by the end of 2024. Out of all mobile subscriptions, 7.2 billion will be associated with a smartphone. – – By 2024, over 30 billion connected devices are forecasted, of which over 20 billion will be related to Internet of Things, IoT. Connected IoT devices including connected cars, machines, meters, sensors, point-of-sale terminals, consumer electronics and wearables. – Mobile data traffic volume is estimated to increase by around three times in the period 2019–2024. The mobile traffic is driven by smartphone users and video traffic. Smartphone traffic will grow by around four times, and mobile video traffic is forecasted to grow by around 30% annually through 2024 to account for approximately 75% of all mobile data traffic. The assumptions are also based upon information gathered in the Company’s long-term strategy process, including assessments of new technology, the Company’s competitive position and new types of business and customers, driven by the continued integration of telecom and data. The value-in-use method is based on specific estimates for the first five years, 2020–2024, and with a nominal annual growth rate of 1% (1%) per year thereafter. An after-tax discount rate of 8.1% (8.8%) has been applied for the discounting of projected after-tax cash flows. The same rate has been applied for all CGUs, since there is a high degree of integration between them. In addition, when a reasonably higher discount rate of 11.0% has been applied in the impairment tests headroom is still positive for all CGUs. For the CGU Emodo in Segment Emerging Business and Other the planned uptake in sales and margin in the business plans have not yet been realized. The carrying amount is SEK 0.5 billion. As a result of the application of IFRS 16 the impairment test has been modified to include also right-of-use assets in the carrying value but not lease liabilities. The Company’s discounting is based on after-tax future cash flows and after-tax discount rates. This discounting is not materially different from a discounting based on before-tax future cash flows and before-tax discount rates, as required by IFRS. In note A1, “Significant accounting policies,” and note A2, “Critical accounting estimates and judgments,” further disclosures are given regarding goodwill impairment testing. The assumptions for 2018 are disclosed in note C1, “Intangible assets” in the Annual Report of 2018.

Risk assessment in the ongoing business is performed monthly to identify the need for new additions and reversals. During certain years the Company undertakes restructuring activities that may require recognition of provisions. Management uses its best judgment to estimate provisions based on this assessment. Under certain circumstances, provisions are no longer required due to outcomes being more favorable than anticipated, which affect the provisions balance as a reversal. In other cases, the outcome can be negative, and if so, a charge is recorded in the income statement. For 2019, new or additional provisions amounting to SEK 7.2 billion were made, and SEK 1.2 billion of provisions were reversed. The actual cash outlays for 2019 were SEK 7.6 billion compared with the estimated SEK 10.0 billion. The expected total cash outlays in 2020 are approximately SEK 9.3 billion. Of the total provisions, SEK 2.7 (5.5) billion is classified as non-current. For more information, see note A1, “Significant accounting policies” and note A2, “Critical accounting estimates and judgments.” Restructuring provisions In 2019, SEK 0.4 billion in provisions were made and SEK 0.3 billion were reversed due to a more favorable outcome than expected. The scope of the structural efficiency measures involves service delivery, supply and manufacturing, R&D and Selling and administrative expenses. The cash outlays for restructuring provisions were SEK 1.8 billion for the full-year, compared with the expected SEK 2.1 billion. The cash outlays for the full-year also includes provisions identified and paid out during 2019. The cash outlays for 2020 for these provisions are estimated to total approximately SEK 1.1 billion. Customer related Customer related provision consists of provision for onerous customer contracts. During 2019, new provisions amounting to SEK 1.3 billion were made for onerous customer contracts where it is probable that expected costs will exceed revenue for the remaining duration of the contracts. SEK 3.2 billion has been reclassified during the year to other The main reason for the difference is due to the reclassification in 2019. Supplier related Supplier related provisions include provision for supplier claims/guarantees. During 2019, new provisions amounting to SEK 1.6 billion were made and SEK 0.7 billion were reversed due to more favorable outcome. The cash outlays were SEK 1.1 billion in 2019 compared to the estimated of SEK 0.9 billion. For 2020, the cash outlays for this provision is estimated to total approximately SEK 1.3 billion. Warranty provisions Warranty provisions are based on historic quality rates for established products as well as estimates regarding quality rates for new products and costs to remedy the various types of faults predicted. These provisions do not include costs for service in additions within customer contracts that are accounted for as separate performance obligations. Provisions amounting to SEK 0.9 billion were made. The actual cash outlays for 2019 were SEK 0.3 billion, compared to the expected SEK 0.3 billion. The cash outlays of warranty provisions during year 2020 are estimated to total approximately SEK 0.8 billion. Other provisions Other provisions include provisions for share-based payments, litigations and other. During 2019, new provisions amounting to SEK 2.9 billion were made (mainly provisions for share-based payments and litigations). However, as disclosed in note A3, “Changes in accounting policies” underlying assets under operating lease contracts are as from 2019 recognized as right-of-use assets. The impact of this transition was SEK 0.8 billion recorded as a reduction of provisions, reclassified to an impairment of right-of-use assets with the same amount for both items. As of December 31, SEK 1.9 billion (including social charges) of the closing balance relates to provisions for share-based payments, see note G3, “Share-based compensation” for more information. The cash outlays were SEK 1.2 billion in 2019 compared to the estimate of SEK 0.6 billion. For 2020, the cash outlays for other provisions are estimated to total approximately SEK 2.4 billion.

Contingent liabilities assumed by the Company include guarantees of loans to other companies of SEK 27 (26) million. All ongoing legal and tax proceedings have been evaluated, their potential economic outflows and probability estimated and necessary provisions made. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied. Financial guarantees for third-parties amounted to SEK 24 (42) million as of December 31, 2019. The maturity date for the majority of the issued guarantees occurs in 2020 at the latest. In April 2018, Telefonaktiebolaget LM Ericsson, the present President and CEO and the Chief Financial Officer of Ericsson as well as three former executives were named defendants in a putative class action filed in the United States District Court for the Southern District of New York. The complaint alleges violations of United States securities laws, principally in connection with service revenues and recognition of expenses on long-term service projects. In October 2018 the plaintiffs filed a first amended complaint. In December 2018 Ericsson filed a motion to dismiss the complaint. In January 2019 the plaintiffs filed a second amended complaint. Ericsson again filed a motion to dismiss the complaint. On January 11, 2020 the court granted Ericsson’s motion to dismiss. At the same time the court granted plaintiffs leave to file a third amended complaint within thirty days. The plaintiffs did not file an amended complaint by the court-ordered deadline. In December 2018, Sol IP sued AT&T, Verizon, and Sprint in East Texas, alleging infringement of 20 patents declared to the LTE standard. Sol IP is a non-practicing entity. The patents originated from Electronics and Telecommunications Research Institute (ETRI), a Korean government-funded research institution. In March 2019, Ericsson intervened in the litigation to defend its products against claims of infringement. In December 2019, Ericsson challenged the patentability of a number of the patents with the Patent Trial and Appeal Board. Ericsson has after the year-end 2019 resolved the litigation with Sol IP. The settlement resolves the litigation with Sol IP and involves a patent license agreement between Ericsson, Sol IP and ETRI. For more information, see note H6, “Events after the reporting period.”

In 2019, Ericsson made acquisitions with a negative cash flow effect amounting to SEK 1,815 (1,220) million. The acquisitions presented below are not material, but the Company gives the information to provide the reader a summarized view of the content of the acquisitions made. The acquisitions consist primarily of: Kathrein : On October 2, 2019, the Company acquired assets from Kathrein, a world leading provider of antenna and filter technologies with approximately 4,000 employees. Kathrein’s antenna and filters business has a strong R&D organization with extensive experience in antenna design and research, coupled with a strong IPR portfolio. In addition to broadening Ericsson’s portfolio of antenna and filter products, the acquisition will bring vital competence for the evolution of advanced radio network products. The acquired Kathrein business has had a negative impact of SEK –0.5 billion since the acquisition, corresponding to –1 percentage point in Networks operating margin. Balances to facilitate the Purchase price allocation are preliminary. CSF: On August 20, 2019, the Company acquired 100% of the shares in CSF Holdings Inc. a US-based technology company with approximately 25 employees. ST-Ericsson: Before ST-Ericsson was a joint venture where Ericsson and ST Microelectronics had a 50/50 ownership. This joint venture consisted of a number of legal entities where the two parties owned different stakes in the different legal entities. In December 2019 the Company initiated transactions to wind-down the legal structure of ST-Ericsson by acquiring the remaining shares in two legal ST-Ericsson entities and costs of SEK –0.3 billion impacted the result.

Disclosure Of Financial Risk Management [Abstract]
F1 Financial risk management	F1 The Company’s financial risk management is governed by a policy approved by the Board of Directors. The Board of Directors is responsible for overseeing the capital structure and financial management of the Company, approving certain matters (such as investments, customer finance commitments, guarantees and borrowing) and setting limits on the exposure to financial risks. For the Company, a robust financial position with an investment grade rating, low leverage and ample liquidity is deemed important. This provides financial flexibility and independence to operate and manage variations in working capital needs as well as to capitalize on business opportunities. The Company’s overall capital structure should support the financial targets. The capital structure is managed by balancing equity, debt financing and liquidity in such a way that the Company can secure funding of operations at a reasonable cost of capital. Regular borrowings are complemented with committed credit facilities to give additional flexibility to manage unforeseen funding needs. The Company strives to deliver strong free cash flow. The Company’s capital objectives are: – Strong cash flow before mergers and acquisition (M&A) – Positive net cash position – Investment grade rating by Moody’s (Baa3), Standard & Poor’s (BBB-) and Fitch (BBB-). Capital objectives-related information, SEK billion 2019 2018 Free cash flow before M&A 7.6 4.3 Positive net cash 34.5 35.9 Credit rating Fitch BBB-, stable BBB-, stable Standard & Poor’s BB+,positive BB+, stable Moody´s Ba2,positive Ba2, stable In July 2019, Moody’s announced that they had changed their Corporate Credit Rating outlook from stable to positive. In September 2019, Standard & Poor’s (S&P) announced that they have changed their Corporate Credit Rating outlook from stable to positive. The Company has a treasury and customer finance function with the principal role to ensure that appropriate financing is in place through loans and committed credit facilities, actively managing the Company’s liquidity as well as financial assets and liabilities, and managing and controlling financial risk exposures in a manner consistent with underlying business risks and financial policies. It also acquires suitable third-party financing solutions for customers and to minimize recourse to the Company. To the extent that customer loans are not provided directly by banks, the Parent Company provides or guarantees vendor credits. The central function also monitors the exposure from outstanding vendor credits and credit commitments. The Company classifies financial risks as: – Foreign exchange risk – Interest rate risk – Credit risk – Liquidity – Refinancing risk – Market price risk in own and other equity instruments. The Board of Directors has established risk limits for defined exposures to foreign exchange and interest rate risks as well as to political risks in certain countries. For further information about accounting policies, see note A1, “Significant accounting policies.” Foreign exchange risk The Company is a global company with sales mainly outside Sweden. Sales and incurred costs are to a large extent denominated in currencies other than SEK and therefore the financial results of the Company are impacted by currency fluctuations. The Company reports the financial statements in SEK. Movements in exchange rates between currencies that affect these statements are impacting the comparability between periods. Line items, primarily sales, are impacted by translation exposure incurred when converting foreign entities’ financial statements into SEK. Line items and profitability, such as operating income are impacted by transaction exposure incurred when financial assets and liabilities, primarily trade receivables and trade payables, are initially recognized and subsequently remeasured due to change in foreign exchange rates. The table below presents the net exposure for the largest currencies impact on sales and also net transaction exposure of these currencies on profitability. Currency exposure, SEK billion Exposure currency Sales translation exposure Sales transaction exposure Sales net exposure Incurred cost transaction exposure 1) Net transaction exposure USD 72.4 34.2 2) 106.6 (11.3) 22.9 EUR 26.2 9.3 35.5 (5.4) 3.9 CNY 12.6 (0.1) 12.5 (8.0) (8.1) INR 8.2 (0.2) 8.0 (1.8) (2.0) AUD 7.5 (0.3) 7.2 3.0 2.7 JPY 8.5 — 8.5 4.6 4.6 BRL 5.8 — 5.8 0.8 0.8 SAR 6.7 0.8 7.5 3.2 4.0 GBP 6.0 (0.7) 5.3 0.8 0.1 1) Transactions in foreign currency – internal sales, internal purchases, external purchases. 2 ) Sales transaction exposure in 2019 does not include volume in the cash flow hedge. Based on the outstanding cash flow hedge volume at year end, the hedged sales volume that will occur in 2020 and 2021 are USD 517 million and USD 176 million respectively. Translation exposure Translation exposure relates to sales and cost incurred in foreign entities when converted into SEK upon consolidation. These exposures cannot be addressed by hedging. Transaction exposure The Company considers three main aspects of transaction exposure. a) Transaction risk impacting net sales and operating income Transaction exposure relates to sales and cost incurred in non-reporting currencies in individual group companies. Foreign exchange risk is as far as possible concentrated in Swedish group companies, primarily Ericsson AB, by selling to foreign subsidiaries in either the functional currency of the customers, EUR or USD. This transaction risk can be hedged, although it is only done for material cash inflows or outflows that are highly certain. The Company has identified certain customer contracts where a fluctuation in the USD/SEK foreign exchange rate would significantly impact net sales and operating income. These contracts are multi-year contracts with highly probable payments at fixed points in time denominated in USD. The Board of Directors has provided a mandate to the Company to hedge between 0%–100% of this exposure up to three years in advance. This mandate instructs the treasury function to hedge a greater percent of this exposure at more favorable rates while hedging a lower percent of the exposure at less favorable rates according to a defined scale. Hedge accounting is applied, whereby the Company enters into foreign exchange forward contracts that match the terms of the foreign exchange exposure as closely as possible and designates them as hedging instruments. Hedge ineffectiveness is expected to be minimal but may arise due to differences in timing of the cash flows between the hedged items and the hedging instruments. b) Transaction exposure in individual balance sheet According to Company policy, transaction exposure in subsidiaries’ balance sheets (e.g., trade receivables and trade payables that are remeasured due to change in foreign exchange rates) should be fully hedged. Foreign exchange exposures in balance sheet items are hedged through offsetting balances or derivatives. Foreign exchange exposures are managed net, and its effects are presented net within Financial income and expenses. This is not designated as hedge accounting. Note F1, cont’d. c) FX execution risk in Ericsson AB (EAB) As balance sheet hedging is done net on a monthly basis, significant volatility in USD hedge volumes exposes EAB to FX execution risk. In order to spread the FX execution risk over the year, 14% of each of the next six months forecasted sales and purchases in EAB are hedged monthly. In previous year 7% of the next 12 months forecast was hedged. The hedged volumes are funded by internal loans from its parent company which are not hedged, therefore the FX impact on revaluation of the loan is recognized in financial income and expenses as incurred. The sensitivity of the FX impact is dependent on changes in foreign exchange rates, forecasts and seasonality. USD is the only currency being hedged and at year-end a change by 0.25 SEK/USD would impact FX in financial income and expenses by approximately SEK 110 million. Realization and revaluation results of these loans contracts amounted to SEK –412 million and SEK 160 million respectively in 2019. Interest rate risk The Company is exposed to interest rate risk through market value fluctuations in certain balance sheet items and through changes in interest revenues and expenses. Sensitivity analysis The Company uses the Value at Risk (VaR) methodology to measure foreign exchange and interest rate risks managed by the treasury function. This statistical method expresses the maximum potential loss that can arise with a certain degree of probability during a certain period of time. For the VaR measurement, the Company has chosen a probability level of 99% and a one-day time horizon. The daily VaR measurement uses market volatilities and correlations based on historical daily data (one year). The treasury function operates under two mandates. In the liquidity management activity, it has a mandate to deviate from floating interest on net liquidity and take foreign exchange positions up to an aggregated risk of VaR SEK 45 million given a confidence level of 99% and a one-day horizon. The average VaR calculated for 2019 was SEK 20.6 (12.8) million. No VaR limits were exceeded during 2019. In the asset-liability management activity, the interest rate risk is managed by matching fixed and floating interest rates in interest-bearing balance sheet items. The policy is that the net sensitivity on a one basis point move on interest-bearing assets matching interest-bearing liabilities, taking derivatives into consideration, is less than SEK 10 million. The average exposure during 2019 was SEK 1.3 (1.8) million per basis point shift. Sensitivity to interest rate increase of 1 basis point, SEK million 1) < 3M 3–12M 1–3Y 3–5Y >5Y Total Interest-bearing assets — — (3) (2) (1) (6) Interest-bearing liabilities 2) — — 3 3 — 6 Derivatives 1 1 (2) (1) 1 — Total 1 1 (2) — — — 1) 2) Outstanding derivatives Outstanding derivatives 2019 Gross amount recognized Offset Net amount presented Related amounts not offset – collaterals Net Currency derivatives Assets 155 (54) 101 — 101 Liabilities (885) 54 (831) 1) 539 (292) Interest rate derivatives Assets 77 (36) 41 — 41 Liabilities (201) 36 (165) — (165) 1) In 2019, currency derivatives designated as cash flow hedge of SEK 290 million are included in Other current liabilities Outstanding derivatives 2018 Gross amount recognized Offset Net amount presented Related amounts not offset – collaterals Net Currency derivatives Assets 319 (44) 275 — 275 Liabilities (637) 44 (593) — (593) Interest rate derivatives Assets 161 (33) 128 — 128 Liabilities (327) 33 (294) — (294) In 2019, the Company entered into Credit Support Annex (CSA) to ISDA for certain cross-currency derivatives. Cash collaterals under CSA are recognized as Interest-bearing securities, current or Borrowings, current, respectively. The Company is holding the following currency derivatives designated as hedging instruments: Foreign exchange forward contracts 2019 < 1 year 1-3 years Total Notional Amount (SEK millions) 517 176 693 Average forward rate (SEK/USD) 9.13 8.92 — Hedge ratio is 1:1 and changes in forward rate have been designated as the hedged risk. The change in the fair value of the hedging instrument is compared with the change in fair value of the hedged item, and the lower amount is taken to OCI. If the change in fair value of the hedging instrument is higher, then the excess change in fair value is considered ineffective hedging and recorded in net foreign exchange gains and losses. Upon recognition of the hedged net sales, the cumulative amount in hedging reserve is released in the OCI as a reclassification adjustment and recognized in net sales. See Note E1, “Equity” for movement in the cash flow hedge reserve. No hedged net sales were recognized in 2019, hence no amount was released from hedging reserve in the OCI. No hedge ineffectiveness was recognized in the income statement in 2019. Credit risk Credit risk is divided into three categories: credit risk in trade receivables and contract assets, customer finance risk and financial credit risk, see note A1, “Significant accounting policies.” Credit risk in trade receivables and contract assets Credit risk in trade receivables and contract assets is governed by a policy applicable to all legal entities in the Company. The purpose of the policy is to: – Avoid credit losses through establishing internal standard credit approval routines in all the Company’s legal entities – Ensure monitoring and risk mitigation of defaulting accounts, i.e. events of non-payment – Ensure efficient credit management within the Company and thereby improve days sales outstanding and cash flow – Define escalation path and approval process for customer credit limits. The credit risk of all customers is regularly assessed. Through credit management system functionality, credit checks are performed every time a sales order or an invoice is generated in the source system. These are based on the credit risk set on the customer. Credit blocks appear if past due receivables are higher than permitted levels. Release of a credit block requires authorization. Letters of credits are used as a method for securing payments from customers operating in emerging markets, in particular in markets with unstable political and/or economic environments. By having banks confirming the letters of credit, the political and commercial credit risk exposures to the Company are mitigated. Note F1, cont’d. Impairment of trade receivables and contract assets Trade receivables and contract assets are assessed for impairment under a unified model. The Company has determined that credit risk largely depends on both the risk in the country where the customer resides (e.g. ability to make cross border payments) as well as the payment pattern of the customer. Therefore, expected credit losses (ECLs) are calculated using a provision matrix that specifies a fixed rate depending both on the number of days past due and the country risk rating. The country risk ratings depend on the ratings used by all Export Credit Agencies within the OECD. The rates defined in the provision matrix are based on historical loss patterns for that grouping of customers. These rates are adjusted for current conditions as well as management expectations for changes to political risks and payment patterns in the future. The provision rates are higher on high risk countries compared to low risk countries and also higher on amounts that remain unpaid for longer periods of time. There were no significant changes to the model during the year. Trade receivables and contract assets together amounted to SEK 55,240 (64,350) million as of December 31, 2019. Provisions for expected credit losses on trade receivables and contract assets amounted to SEK 2,983 (4,123) million as of December 31, 2019. The allowance decreased in 2019 due to improvement in cash collection resulting in significant reduction of total past due invoices. The Company’s write-offs have historically been low. During the year SEK 382 (890) million were written off due to the Company having no reasonable expectation of collection. Of these write-offs, SEK 0 (61) million are still subject to enforcement. Movements in allowances for impairment of trade receivables and contract assets 2019 2018 Opening balance 4,123 4,575 Decrease (-)/increase (+) in allowance (737) 420 Write-offs (382) (890) Translation difference (21) 18 Closing balance 1) 2,983 4,123 1 ) Of which SEK 0 (15) million relates to contract assets. The distribution of trade receivables and contract assets closely follows the distribution of the Company’s sales, see note B1, “Segment information.” The ten largest customers represented 49% (53%) of the total trade receivables and contract assets in 2019. Aging analysis of gross values by risk category at December 31, 2019 Days past due 1–90 91–180 181–360 >360 Total Country risk: Low 1,347 125 127 313 1,912 Country risk: Medium 891 725 600 819 3,035 Country risk: High 583 365 217 1,315 2,480 Total past due 2,821 1,215 944 2,447 7,427 Customer finance credit risk All major commitments to finance customers are made only after approval in accordance with the work procedure for the Board of Directors and according to the established credit approval process. Prior to the approval of new facilities reported as customer finance, an internal credit risk assessment is conducted in order to assess the credit rating of each transaction for political and commercial risk. The credit risk analysis is made by using an assessment tool, where the political risk rating is identical to the rating used by all Export Credit Agencies within the OECD. The commercial risk is assessed by analysing a large number of parameters, which may affect the level of the future commercial credit risk exposure. The output from the assessment tool for the credit rating also includes an internal pricing of the risk. This is expressed as a risk margin per annum over funding cost. The reference pricing for political and commercial risk, on which the tool is based, is reviewed using information from Export Credit Agencies and prevailing pricing in the bank loan and bond markets for structured financed deals. The objective is that the internally set risk margin shall reflect the assessed risk and that the pricing is as close as possible to the current market pricing. A reassessment of the credit rating for each customer finance facility is made on a regular basis. As of December 31, 2019, the total amount payable to the Company under customer finance credits was SEK 5,924 (4,247) million. The carrying value of these assets was SEK 3,756 (2,883) million as of December 31, 2019, which represents the maximum exposure to credit risk on these assets. Customer finance is arranged for infrastructure projects in different geographic markets. As of December 31, 2019, there were a total of 80 (94) customer finance arrangements originated by or guaranteed by the Company. The five largest facilities represented 69% (62%) of the customer finance exposure in 2019. As of December 31, 2019, Middle East and Africa made up 49% (57%) of the outstanding exposure while South East Asia, Oceania and India made up 29% (15%). As of December 31, 2019, the Company also had unutilized customer finance commitments of SEK 25,854 (30,270) million. Security arrangements for customer finance facilities may include pledges of equipment, pledges of certain assets belonging to the borrower and pledges of shares in the operating company. If available, third-party risk coverage is, as a rule, arranged. “Third-party risk coverage” means that a financial payment guarantee covering the credit risk has been issued by a bank, an export credit agency or an insurance company. All such institutions have been rated at least investment grade. A credit risk transfer under a sub-participation arrangement with a bank can also be arranged. In this case the entire credit risk and the funding is taken care of by the bank for the part that they cover. Information about financial guarantees related to customer finance is included in note D2, “Contingent liabilities.” The table below summarizes the Company’s outstanding customer finance as of December 31, 2019 and 2018. Outstanding customer finance credit risk exposure 1) 2019 2018 Fair value of customer finance credits 3,756 2,883 Financial guarantees for third-parties 24 42 Accrued interest 14 21 Maximum exposure to credit risk 3,794 2,946 Less third-party risk coverage (309) (331) The Company’s risk exposure, less third-party risk coverage 3,485 2,615 1) This table has been adjusted to show the maximum exposure to credit risk. Fair value assessment of customer finance credits Customer finance risk exposures are held at fair value and are classified as Level 3 on the fair value hierarchy. The Credit Asset Management Team within Ericsson Credit AB, reporting to Head of Group Treasury and Customer Finance, has established a process with respect to measurement of fair values. The quarterly credit review uses an internal model to determine a commercial rating for each credit and for calculation of the fair value. The model is based on external credit rating, political/country rating and bank pricing. Regular monitoring of customer behavior is also a part of the internal assessment. Revaluation of customer finance amounted to a net negative impact in the income statement of SEK 804 (1,073) million in 2019, of which SEK 804 (1,073) million is related to credits held as of December 31, 2019. This effect is presented within selling and administrative expenses and was mainly related to India and the Middle East, especially Iran and Iraq. Customer finance fair value reconciliation 2019 2018 Opening balance 2,884 3,931 Additions 29,732 6,100 Disposals/repayments (28,032) (6,200) Revaluation (804) (1,073) Translation difference (24) 126 Closing balance 3,756 2,884 Of which non-current 2,262 1,180 Due to the increase in 5G buildout this year, demand for customer financing solutions has increased. Most of such financing has been successfully transferred to banks, hence the balance of customer finance receivables remains low. Note F1, cont’d. Financial credit risk Financial instruments carry an element of risk in that counterparts may be unable to fulfill their payment obligations. This exposure arises in the investments in cash, cash equivalents, interest-bearing securities and from derivative positions with positive unrealized results against banks and other counterparties. The Company mitigates these risks by investing cash primarily in high rated securities such as treasury bills, government bonds, commercial papers, and mortgage-covered bonds (see Liquidity risk section below). Separate credit limits are assigned to each counterpart in order to minimize risk concentration. All derivative transactions are covered by ISDA netting agreements to reduce the credit risk. For cross-currency swaps a Credit Support Annex (CSA) to ISDA is signed to further reduce the credit risk by exchanging collateral weekly against market value. The Company has also moved some derivative exposures to clearing counterparties with daily settlement of margins. At December 31, 2019, the credit risk in financial cash instruments was equal to the instruments’ carrying value. The expected credit losses on cash equivalents and interest-bearings securities classified as amortized cost were immaterial. Credit exposure in derivative instruments was SEK 0.1 (0.4) billion. Transfers of financial assets Transfers where the Company has continuing involvement During 2019, there were no new financial assets transferred where the Company had retained continuing involvement. However, during 2016 the Company derecognized financial assets where it had retained continuing involvement. A repurchase of these assets would have amounted to SEK 207 million at the end of 2018. This contract was concluded in 2019. Liquidity risk The Company minimizes the liquidity risk by maintaining a sufficient cash position, centralized cash management, investments in highly liquid interest-bearing securities, and by having sufficient committed credit lines in place to meet potential funding needs. For information about contractual obligations, see note D4, “Contractual obligations.” The current cash position is deemed to satisfy all short-term liquidity requirements.

Debt financing is mainly carried out through borrowing in the Swedish and international debt capital markets. Bank financing is used for certain subsidiary funding and to obtain committed credit facilities.

In October 2019, the Company signed a multicurrency credit facility agreement equivalent to EUR 250 million with the European Investment Bank. The maturity date of the credit facility will be determined at the time of disbursement and can be up to seven years after disbursement. The agreement will support research and development activities for 5G. Committed credit facilities Amount Utilized Unutilized Multi-currency revolving credit facility (USD million) 2,000 — 2,000 European Investment Bank (EIB) credit facility (EUR million) 250 — 250 Fair valuation of the Company’s financial instruments The Company’s financial instruments accounted for at fair value generally meet the requirements of level 1 valuation due to the fact that they are based on quoted prices in active markets for identical assets. Exceptions to this relates to: – OTC derivatives with an amount of gross SEK 0.2 (0.5) billion in relation to assets and gross SEK 1.1 (1.0) billion in relation to liabilities were valued based on references to other market data as currency or interest rates. These valuations fall under level 2 valuation as defined by IFRS. – Ownership in other companies and other financial investments where the Company neither has control nor significant influence. The amount recognized in these cases was SEK 2.6 (2.5) billion. Net revaluation gains or losses is SEK 0 (0) billion in the year. These assets, classified as level 3 assets for valuation purposes, have been valued based on value in use technique. – Customer finance credits are classified as level 3 assets for valuation purposes and have been valued according to the model described above in “Customer finance credit risk.” – Trade receivables are classified as level 3 assets for valuation purposes. By definition, they have a term of less than 180 days. Therefore, the gross value less impairment allowances for expected credit losses is deemed to be equal to the fair value. Financial instruments carried at other than fair value Financial instruments, such as some cash equivalents, interest-bearing securities, borrowings and payables, are carried at amortized cost which is deemed to be equal to fair value. When a market price is not readily available and there is insignificant interest rate exposure and credit spreads affecting the value, the carrying value is considered to represent a reasonable estimate of fair value. Note F1, cont’d. Market price risk in own shares and other listed equity investments The Company is exposed to fluctuations in its own share price (through stock purchase plans for employees) and other share-based compensation for employees and the Board of Directors. Some of the plans are share-settled and some are cash-settled as further disclosed in note A1, “Significant accounting policies” and note G3, “Share-based compensation.” Share-based plans for employees The obligation to deliver shares under the stock purchase plan and the 2017 Long-Term Variable compensation program (LTV) 2017 for the Executive team is covered by holding Ericsson Class B shares as treasury stock. The cash flow exposure is hedged through the holding of Ericsson Class B shares as treasury stock to be sold to generate funds, which also cover social security payments. The obligation to deliver shares under the 2018 and 2019 LTV programs for the Executive team shall be hedged by the Company entering into an equity swap agreement with a third party, under which the third party shall, in its own name, acquire and transfer Ericsson Class B shares to employees covered by these programs. A change in the share price will result in a change in social security charges, which represents a risk to the income statement. Cash-settled plans to employees and the Board of Directors In the case of synthetic share programs (a cash-settled program as defined in IFRS 2) to Board members and cash-settled plans to employees, the Company is exposed to risks in relation to own share price, both with regard to compensation expenses and social security charges. The obligations to pay compensation amounts under the synthetic share-based compensations to the Board of Directors and employees are covered by a provision in the balance sheet.

All outstanding notes and bond loans are issued by the Parent Company under its Euro Medium Term Note (EMTN) program or under its US Securities and Exchange Commission (SEC) Registered program. Bonds issued at a fixed interest rate are normally swapped to a floating interest rate using interest rate swaps under the Asset and liability management mandate described in note F1, “Financial risk management.” Total weighted average interest rate cost for the long-term funding during the year was 3.26% (3.01%). In July 2019, the Company made a drawdown of USD 281 million under the European Investment Bank (EIB) loan facility signed in May 2018. The loan supports research and development activities related to 5G. The loan will mature in July 2024. Ericsson drew on the credit facility of USD 150 million, from the Nordic Investment Bank (NIB), which was signed in December 2019 to support investments in R&D for 5G technology. Part of the new funds, USD 98 million, replaced an existing credit with NIB that was set to mature in 2021, resulting in a net increase in funding of USD 52 million. The new facility is set to mature in 2025. Changes in fair value due to changes in credit risk Borrowings issued by the Parent Company are designated FVTPL because they are managed on a fair value basis. Changes in fair value are recognized in the income statement, except for changes in fair value due to changes in credit risk which are recognized in other comprehensive income. Ericsson’s credit risk is calculated from the market value of the instruments traded on the credit market. For interest bearing securities not traded on the credit market, an average of the five latest pricing updates from the Company’s core banks is used. The pricing updates are based on the credit markets view of Ericsson’s credit and therefore reflects a market price of the credit risk.

Disclosure Of Information About Defined Benefit Plans [Abstract]
G1 Post-employment benefits	G1 Ericsson sponsors a number of post-employment benefit plans throughout the Company, which are in line with market practice in each country. The main change in 2019 was driven by a decrease in discount rates in most pension plans. In total, financial assumption changes resulted in actuarial losses on defined benefit obligations of SEK 12.4 billion. The development of plan assets was higher than expected resulting in actuarial gains of SEK 5.8 billion. Swedish plans Sweden has both defined benefit and defined contribution plans based on collective agreement between the parties in the Swedish labor market: – A defined benefit plan, known as ITP 2 (occupational pension for salaried employees in manufacturing industries and trade), complemented by a defined contribution plan, known as ITPK (supplementary retirement benefits). This is a final salary-based plan. – A defined contribution plan, known as ITP 1, for employees born in 1979 or later. – A defined contribution plan ITP 1 or alternative ITP, for employees earning more than 10 income base amount and who have opted out of the defined benefit plan ITP 2, where rules are set by the Company and approved by each employee selected to participate. The Company has by far most of its Swedish pension liabilities under defined benefit plans which according to IAS 19 is funded to 45% (49%) by the assets of Ericsson Pensionsstiftelse (a Swedish Pension Foundation). According to Swedish GAAP these liabilities are considered funded to more than 100% by the assets of Ericsson Pensionsstiftelse. There are no funding requirements for the Swedish plans. The disability and survivors’ pension part of the ITP-plan is secured through an insurance solution with the company Alecta, see section about Multi-employer plans. The Company pays benefit directly to the pensioners as the obligations fall due. The responsibility for governance of the plans and the plan assets lies with the Company and the Pensionsstiftelse. The Swedish Pensionsstiftelse is managed on the basis of a capital preservation strategy and the risk profile is set accordingly. Traditional asset-liability matching (ALM) studies are undertaken on a regular basis to allocate within different asset classes. The plans are exposed to various risks, e.g., a sudden decrease in the bond yields, which would lead to an increase in the plan liability. A sudden instability in the financial market might also lead to a decrease in fair value of plan assets held by the Pensionsstiftelse, as the holdings of plan assets partly are exposed to equity markets; however, this may be partly offset by higher values in fixed income holdings. Swedish plans are linked to inflation and higher inflation will most likely lead to a higher liability. For the time being, inflation is a low risk factor to the Swedish plans as actual rate of inflation has not reached the ceiling target set by the Central Bank of Sweden. Multi-employer plans As before, the Company has secured the disability and survivors’ pension part of the ITP Plan through an insurance solution with the insurance company Alecta. Although this part of the plan is classified as a multi-employer defined benefit plan, it is not possible to get sufficient information to apply defined benefit accounting, as for most of the accrued pension benefits in Alecta, information is missing on the allocation of earnings process between employers. Full vesting is instead registered on the last employer. Alecta is not able to calculate a breakdown of assets and provisions for each respective employer, and therefore, the disability and survivors’ pension portion of the ITP Plan has been accounted for as a defined contribution plan. Alecta has a collective funding ratio which acts as a buffer for its insurance commitments to protect against fluctuations in investment return and insurance risks. Alecta’s target ratio is 140% and reflects the fair value of Alecta’s plan assets as a percentage of plan commitments, then measured in accordance with Alecta’s actuarial assumptions, which are different from those in IAS 19. Alecta’s collective funding ratio was 148% (142%) as of December 31, 2019. The Company’s share of Alecta’s saving premiums is 0.3%, the total share of active members in Alecta are 1.9%. The expected contribution to the plan is SEK 106 million for 2020. Contingent liabilities / Assets pledged as collateral Contingent liabilities include the Company’s mutual responsibility as a credit insured company of PRI Pensionsgaranti in Sweden. This mutual responsibility can only be imposed in the instance that PRI Pensionsgaranti has consumed all of its assets, and it amounts to a maximum of 2% of the Company’s pension liability in Sweden. The Company has a pledged business mortgage of SEK 5.1 billion to PRI Pensionsgaranti. US plans The Company operates both defined contribution and defined benefit pension plans in the US, which are a combination of final salary pension plans and contribution-based arrangements. The final salary pension plans provide benefits to members in the form of a guaranteed level of pension payable for life. The level of benefits provided depends on members’ length of service and their salary in the final years leading up to retirement. Retirees generally do not receive inflationary increases once in payment. The other type of plan is a contribution-based pension plan, which provides a benefit determined using a “cash balance” approach. The balance is credited monthly with interest credits and contribution credits, based on a combination of current year salary and length of service. The majority of benefit payments are from trustee-administered funds; however, there are also a number of unfunded plans where the Company meets the benefit payment obligation as it falls due. In the US, the Company’s policy is at least to meet or exceed the funding requirements of federal regulations. The funded level in the US Pension Plan is above the point at which minimum funding would be required for fiscal year 2019. Plan assets held in trusts are governed by local regulations and practice, as is the nature of the relationship between the Company and the trustees (or equivalent) and their composition. Responsibility for governance of the plans, including investment decisions and contribution schedules, lies with the Plan Administrative Committee (PAC). The PAC is composed of representatives from the Company. The Company’s plans are exposed to various risks associated with pension plans, i.e., a sudden decrease in bond yields would lead to an increase in the present value of the defined benefit obligation. A sudden instability in the financial markets might also lead to a decrease in the fair value of plan assets held by the trust. Pension benefits in the US are not linked to inflation; however, higher inflation poses the risk of increased final salaries being used to determine benefits for active employees. There is also a risk that the duration of payments to retirees will exceed the life expectancy in mortality tables. UK plans The Company operates both defined benefit and defined contribution plans in the UK. All defined benefit plans in the UK are closed to future pension accrual. The defined benefit plans provide benefits to members in the form of a guaranteed level of pension payable for life. The level of benefits provided is defined by the Trust Deed & Rules and depends on members’ length of service and their salary. Pensions in payment are generally updated in line with the UK retail price index, subject to caps defined by the rules. The plans’ assets are held in trusts and are invested in a diverse range of assets. The plans are governed by local regulations and responsibility for the governance of the plans lies with the Trustee Directors, who are appointed by the Company from its employees and from the plans’ members. Independent professional trustees sit on a number of the Boards. Note G1, cont’d. The plans remain exposed to various risks associated with defined benefit plans, e.g. a decrease in bond yields or increase in inflation would lead to an increase in the present value of the defined benefit obligation. Alternatively, the duration of payments to retirees could exceed the life expectancy assumed in the current mortality tables leading to an increase in liabilities. A sudden instability in the financial markets might also lead to a decrease in the fair value of the plans’ assets. The Company and Trustees’ aim is to reduce the plans’ exposure to the key risks over time. Other plans The Company also sponsors plans in other countries. The main plans are in Brazil and Ireland. The main pension plans in Brazil are wholly funded with a net surplus of assets. The plan in Ireland is a final salary pension plan and is partly funded. The plans are managed by corporate trustees with directors appointed partly by the local company and partly by the plan members. The trustees are independent from the local company and subject to the specific country’s pension laws.

See also note A1, “Significant accounting policies” and note A2, “Critical accounting estimates and judgments.” Sweden The defined benefit obligation (DBO) has been calculated using a discount rate based on the yields of Swedish government bonds. IAS 19 Employee Benefits prescribes that if there is not a deep market in high-quality corporate bonds, the market yields on government bonds shall be applied for the pension liability calculation. As of December 31, 2019, the discount rate applied in Sweden was 0.9% (1.5%). If the discount rate had been based on Swedish covered bonds, the discount rate as of December 31, 2019 would have been 1.8% (2.5%).

The number of synthetic shares is rounded down to the nearest whole number of shares. The synthetic shares are vested during the Directors’ term of office and the right to receive payment with regard to the allocated synthetic shares occurs after the publication of the Company’s year-end financial statement during the fifth year following the Annual General Meeting which resolved on the synthetic share program, i.e., in 2024.

Guidelines for remuneration to Group management 2019 For Group management consisting of the Executive Team (ET), including the President and CEO, total remuneration consists of fixed salary, short- and long-term variable compensation, pension and other benefits. The following guidelines apply to the remuneration of the Executive Team: – Variable compensation is in cash and stock-based programs awarded against specific business targets derived from the long-term business plan approved by the Board of Directors. Targets may include share-price related or financial targets at either Group or unit level, operational targets, employee engagement targets or customer satisfaction targets. – All benefits, including pension benefits, follow the competitive practice in the home country taking total compensation into account. – By way of exception, additional arrangements can be made when deemed necessary. An additional arrangement can be renewed but each such arrangement shall be limited in time and shall not exceed a period of 36 months and twice the remuneration that the individual would have received had no additional arrangement been made. – The standard mutual notice period is no more than six months. Upon termination of employment by the Company, severance pay amounting to a maximum of 18 months fixed salary is paid. Notice of termination given by the employee due to significant structural changes, or other events that in a determining manner affect the content of work or the condition for the position, is equated with notice of termination served by the Company. – On a case to case basis, the mutual notice period can be increased to no more than 12 months in which case there will be a corresponding reduction in severance pay (where applicable). In all circumstances, fixed salary during the notice period plus any severance pay payable will not together exceed an amount equivalent to the individual’s 24 months fixed salary. Remuneration costs The total remuneration to the President and CEO and to other members of the Group management, consisting of the ET, includes fixed salary, short- and long-term variable compensation, pension and other benefits. These remuneration elements are based on the guidelines for remuneration to Group management as approved by the Annual General Meeting (AGM) of shareholders held in 2019: see the approved guidelines in the previous section Guidelines for remuneration to Group management 2019.

Disclosure Of Terms And Conditions Of Sharebased Payment Arrangement [Abstract]
G3 Share-based compensation	G3 Accounting treatment of Long-Term Variable Compensation Programs In note A1,” Significant accounting policies”, the overall accounting policies for share-based payments within the Company are disclosed. In summary: – For share-settled plans, the total compensation expense is calculated based on the fair value (FV) at grant date and recognized over the service period of three years. – For the cash-settled plans the accounting principles are the same as for any other accruals or provisions. Prior to payout an accrual or provision is recognized every period based on the present period’s best estimate of the total amount. Any difference between total payout and the sum of accruals of provisions is recognized in the income statement in the period of final payout. Long-Term Variable Compensation All long-term variable compensation programs have been designed to form a part of a well-balanced total remuneration package and in general to span over a minimum of three years (vesting period). As these are variable compensation programs, the outcomes cannot be predicted when the programs are introduced and rewards depend on long-term personal commitment, corporate performance and the share price performance. Following discontinuation of the previous long-term variable compensation programs at the end of 2016, the Company introduced the new Long-Term Variable Compensation Program (LTV) for the Executive Team (ET), the new Executive Performance Plan (EPP) for senior managers and the Key Contributor Plan (KC Plan) for key employees as integral parts of its remuneration strategy starting from 2017. All new programs are share-based payment programs as defined by IFRS 2 “share-based payment,” either share- or cash-settled. Share-Settled Programs Long-Term Variable Compensation Program for the Executive Team The Long-Term Variable Compensation Program for the ET is designed to provide long-term incentives for members of the ET and to incentivize the Company’s performance creating long-term value. These are share-settled plans as defined by IFRS 2. Awards under LTV (Performance Share Awards) are granted to the participants, provided that certain performance conditions are met, to receive a number of shares, free of charge, following expiration of a three-year vesting period (performance period). Allotment of shares pursuant to Performance Share Awards are subject to the achievement of challenging performance criteria which are defined specific to each year’s program when the program is introduced. Which portion, if any, of the Performance Share Awards for LTV will vest is determined at the end of the relevant performance period based on the satisfaction of the predetermined performance criteria for that year’s LTV program. The performance criteria for the currently running LTV and EPP are summarized in the below table along with the satisfaction and achieved vesting levels for the ones which the performance period have lapsed. It is generally required that the participant retains his or her employment over a period of three years from the date of grant of awards (service period) to be eligible for receiving the performance awards. Provided that the performance criteria have been met during the performance period and that the participant has retained his or her employment (unless special circumstances are at hand) during the service period, allotment of vested shares will take place as soon as practicably possible following the expiration of the vesting period. When determining the final vesting level of Performance Share Awards, the Board of Directors examines whether the vesting level is reasonable considering the Company’s financial results and position, conditions on the stock market and other circumstances, and if not, reserves the right to reduce the vesting level to a lower level deemed appropriate. In the event delivery of shares to the participants cannot take place under applicable law or at a reasonable cost and employing reasonable administrative measures, the Board of Directors is entitled to decide that participants may, instead, be offered cash settlement. All major decisions relating to outcome of LTV are taken by the Remuneration Committee, with approval by the full Board of Directors as required.

The vesting of the performance share awards under this performance condition will vary depending on the Company’s TSR performance ranking versus the other companies in the peer group at the end of the performance period. 2 ) Excludes fines and similar related to the United States Department of Justice (DOJ) / Securities and Exchange Commission (SEC) investigation. 3 ) Excludes restructuring charges and the provisions taken in Q4 2018 related to the revised BSS strategy. Note G3, cont’d. 2019 Long-Term Variable Compensation Program for the Executive Team (LTV 2019) LTV 2019 was approved at the AGM 2019 and includes a total of 14 ET members in 2019, including the President and CEO, but excluding Helena Norrman who was not granted LTV 2019 due to her resignation, and Stella Medlicott and Fadi Pharaon who carried over their EPP entitlements for 2019 after their appointments to the ET. The participants were granted Performance Share Awards on May 18, 2019. The value of the underlying shares in respect of the Performance Share Award made to the President and CEO was 180% of the annual base salary, and for other participants ranged between 30% and 70% of the participants’ respective annual base salaries at the time of grant. The share price used to calculate the number of shares to which the Performance Share Award entitles was calculated as the volume weighted average of the market price of Ericsson B shares on Nasdaq Stockholm during the five trading days immediately following the publication of the Company’s interim report for the first quarter of 2019. Following evaluation of the previously introduced Long-Term Variable Compensation Programs, the Board of Directors decided to use the same performance criteria for LTV 2019 as the ones used for LTV 2018 in order to secure continuity and consistency in supporting achievement of the Company’s 2020 targets. Hence again a one-year Group operating income target measured over the period January 1, 2019 to December 31, 2019 was included as a performance condition for LTV 2019 in addition to the standard three-year total shareholder return (TSR) performance conditions, which were also used for LTV 2018 and LTV 2017. The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2019 to December 31, 2021 (the performance period). The performance criteria for LTV 2019 along with the details on how the performance criteria will be calculated and measured are explained in minutes from the AGM 2019 under Item 17. The Board of Directors resolved on the achieved vesting level for the 2019 Group operating income performance criteria as 200% for this portion of the performance share awards granted based on a 2019 Group operating income outcome excluding fines and similar related to the United States Department of Justice (DOJ) / Securities and Exchange Commission (SEC) investigation. 2018 Long-Term Variable Compensation Program for the Executive Team (LTV 2018) LTV 2018 was approved by the AGM 2018 and includes all members of the ET, a total of 14 employees in 2018, including the President and CEO, but excluding Ulf Ewaldsson, Elaine Weidman-Grunewald and Nina Macpherson who left the ET prior to the award grant date of May 18, 2018, and Jan Karlsson who carried over his EPP entitlement for 2018 after his appointment to the ET. The participants were granted Performance Share Awards on May 18, 2018. The value of the underlying shares in respect of the Performance Share Award made to the President and CEO was 180% of the annual base salary, and for other participants ranged between 30% and 70% of the participants’ respective annual base salaries at the time of grant. The maximum value of underlying shares in respect of the Performance Share Awards made to the ET members other than the President and CEO were increased from 22.5% in 2017 to between 30% and 70% of participants’ respective base salaries at the time of grant in 2018. The increases were approved at the AGM 2018 with the intention to increase the long- term Following continuous evaluation of the Long-Term Variable Compensation Programs a one-year Group operating income target was added to LTV 2018 measured over the period January 1, 2018 to December 31, 2018, to support achieving the Company’s 2020 targets, in addition to the three-year targets relating to total shareholder return (TSR), which were also used for LTV 2017. The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2018 to December 31, 2020 (the performance period). The performance criteria for LTV 2018 along with the details on how the performance criteria will be calculated and measured are explained in minutes from the AGM 2018 under Item 17. The Board of Directors resolved on the achieved vesting level for the 2018 Group operating income performance criteria as 200% for this portion of the performance share awards granted based on a 2018 Group operating income outcome excluding restructuring charges and the provisions taken in Q4 2018 related to the revised BSS strategy. 2017 Long-Term Variable Compensation Program for the Executive Team (LTV 2017) LTV 2017 was approved at the AGM 2017 and includes all members of the ET, a total of 16 employees in 2017, including the President and CEO. The participants were granted Performance Share Awards on May 18, 2017. The value of the underlying shares in respect of the Performance Share Award made to the President and CEO was 180% of the annual base salary, and for other participants 22.5% of the participants’ respective annual base salaries at the time of grant. The share price used to calculate the number of shares to which the Performance Share Award entitles was calculated as the volume-weighted average of the market price of Ericsson B shares on Nasdaq Stockholm during the five trading days immediately following the publication of the Company’s interim report for the first quarter of 2017. Absolute and relative TSR development for the Ericsson B share over the period January 1, 2017 to December 31, 2019 (the performance period) were the two performance criteria used for LTV 2017. The performance criteria for LTV 2017 along with the details on how the performance criteria will be calculated and measured are explained in minutes from the AGM 2017 under Item 17. The Board of Directors resolved on the achieved vesting levels for the absolute and relative TSR development performance criteria as 200% and 191.04% respectively based on the achievement results of 21.34% absolute TSR and 5.45th ranking for relative TSR, which resulted in an overall achieved vesting level of 195.52% for LTV 2017 as illustrated in the table LTV and EPP Performance Criteria on the prior page. The total number of maximum shares required and the related total compensation expenses for the currently running share-settled long-term variable compensation programs for the President and CEO and the ET are summarized in the table below.

Note G3, cont’d. Compensation expense of Long-Term Variable Compensation Programs for the Executive Team The total compensation expense for the share-settled long-term variable compensation programs for the President and CEO and the ET during 2019 were SEK 58 million as shown in the table above. The compensation expense is based on FV and the number of shares. The FV for the ET LTV programs are including adjustments for absolute and relative TSR development performance criteria at the grant date, using a Monte Carlo model, which uses a number of inputs, including expected dividends, expected share price volatility and the expected period to exercise. The performance criteria of the LTV program is also based on the outcome of the Group operating income as per fiscal years 2019 and 2018. The FV for the Group operating income performance criteria is calculated as the share price at grant date, reduced by the net present value of the dividend expected during the three-year vesting period.

Senior managers, except for the members of the ET, are selected as participants to EPP annually through a nomination process that identifies individuals according to performance, potential, critical skills, and business critical roles. The number of senior managers selected as participants in EPP for 2019, 2018 and 2017 were 161, 171 and 452 respectively. There are two award levels at 15% and 22.5% of the participants’ annual gross salary. Participants are assigned a potential award, which is converted into a number of synthetic shares based on the same market price of Ericsson B shares used for the respective year’s LTV. The three-year vesting period is the same as for the LTV. The vesting level of the award is subject to the achievement of the same performance criteria over the same performance period defined for the respective year and generally requires that the participant retains his or her employment over the vesting period. At the end of the vesting period, the allotted synthetic shares are converted into a cash amount, based on the market price of Ericsson B shares at Nasdaq Stockholm at the payout date, and this final amount is paid to the participant in cash gross before tax. Key Contributor Plans (KC Plans) The KC Plan is a cash-settled retention plan. Employees, except for senior managers and the members of the ET, are selected as participants to KC Plan annually through a nomination process that identifies individuals according to performance, potential, critical skills, and business critical roles. Participants are assigned a potential award based on a percentage of their annual gross salary, which is converted into a number of synthetic shares based on the same market price of Ericsson B shares used for the respective year’s LTV. The KC Plan is a retention plan, therefore there are no performance criteria for vesting of awards. In general, there is a three-year service period for receiving the award in full and the award is subject only to continued employment during the service period. The value of each synthetic share is driven by the absolute share price performance of Ericsson B shares during the service period. At the end of the service period, the allotted synthetic shares are converted into a cash amount, based on the market price of Ericsson B shares Nasdaq Stockholm at the payout date, and this final amount is paid to the participant in cash gross before tax. Key Contributor Plan 2019 (KC Plan 2019) 6,941 employees were selected to participate in KC Plan 2019. There are three award levels at 10%, 25% and 30% of the participants’ annual gross salary. The total service period is three years, however the payout is distributed over the entire service period with staggered payments according to the below schedule: – 25% of the award to be paid at the end of the first year, – 25% of the award to be paid at the end of the second year, and – the remaining 50% of the award to be paid at the end of the third year. From an accounting perspective the plans with three staggered payments are seen as three separate tranches. The tranches are accounted for as separate awards and accrued in parallel with the same grant date but different vesting dates. Due to this the cost for the KC Plan 2019 is front-end loaded. The accounting model is referred to as staged vesting. Key Contributor Plan 2018 (KC Plan 2018) 5,886 employees were selected to participate in KC Plan 2018. There are two award levels at 10% and 25% of the participants’ annual gross salary. The total service period is three years and the awards are paid at the end of the full service period.

Note G3, cont’d. Key Contributor Plan 2017 (KC Plan 2017) 6,876 employees were selected to participate in KC Plan 2017. There are two award levels at 10% and 25% of the participants’ annual gross salary. The total service period is three years and the awards are paid at the end of the full service period. Compensation expense of Cash-settled Plans The total compensation expenses for the EPP and the KC Plans during 2019 were SEK 180.4 million and SEK 765.5 million respectively as shown in the table Cash-settled plans. The total provision for the cash-settled plans amounted to SEK 1,941 million (including social charges of 216 million) at the end of 2019. The compensation expense is based on the FV and the number of synthetic shares allocated. The FV for the cash-settled plans are shown in the table Fair value cash-settled plans below. Fair value cash-settled plans Executive performance plans (SEK) EPP 2019 EPP 2018 EPP 2017 Fair value Absolute TSR 69.86 147.77 173.59 Fair value Relative TSR 86.50 130.14 161.80 Fair value Group operating income 83.14 85.28 — Key contributor plans KC 2019 KC 2018 KC 2017 Fair value – T1 86.27 — — Fair value – T2 84.69 — — Fair value – T3 83.14 — — Fair value — 85.28 86.87 The FV for the EPP is including adjustments for absolute and relative TSR performance criteria, using a Monte Carlo model, which uses a number of inputs, including expected dividends, expected share price volatility and the expected period to exercise. The FV for the Group operating income performance criteria is the share price reduced by the net present value of the dividend expected during the vesting period. This performance condition is based on the outcome of the Group operating income performance criteria as per fiscal year 2019 and 2018 and adjusts the number of synthetic shares. The FV for the KC Plans are the share price reduced by the net present value of the dividend expected during the vesting period. For KC Plan 2019 the FV differ based on the three different vesting periods. The Stock Purchase Plan (SPP) The SPP was a share-settled plan designed to offer an incentive for all employees to participate in the Company’s long-term variable compensation program where practicable. Under SPP employees were able to save up to 7.5% of their gross fixed salary for purchase of Ericsson B contribution shares at market price on NASDAQ Stockholm or American Depositary Shares (ADSs) on Nasdaq New York (contribution shares) during a twelve-month period (contribution period). If the contribution shares were retained by the employee for three years after the investment and their employment with the Ericsson Group continued during that time, then the employee’s shares are to be matched with a corresponding number of Ericsson B shares or ADSs free of consideration. Employees in 100 countries participated in the SPP. The table below shows the contribution period and participation details for the only open SPP from 2016 as of December 31, 2019. Stock Purchase Plans Plan Contribution period Number of participants at launch Take-up rate – percent of eligible employees August 2016 – Stock Purchase plan 2016 July 2017 31,500 29% The total cost of SPP for the three years of service is based on the number of shares that vest, due to savings and calculated based on the FV of the shares as defined at grant date. The Key Contributor Retention Plan The Key Contributor Retention Plan was part of Ericsson’s talent management strategy and was designed to give recognition for performance, critical skills and potential as well as to encourage retention of key employees. Under the program, up to 10% of the employees were selected through a nomination process that identified individuals according to performance, critical skills and potential. Participants selected obtained one extra matching share in addition to the ordinary one matching share for each Contribution Share purchased under SPP during a twelve-month period. Since no SPP was proposed after 2016, the cash based KC Plan described above was introduced replacing the Key Contributor Retention Plan. The accounting treatment for the Key Contributor Retention Plan is the same as for SPP, however these employees receive two additional shares for each share invested. The Executive Performance Stock Plan (EPSP) The EPSP was a share-settled program. Senior managers, including the members of the ET, were selected to obtain up to four or six extra shares (performance matching shares) in addition to the ordinary one matching share for each contribution share purchased under SPP. Up to 0.5% of employees were offered participation in EPSP. The performance targets were linked to growth of net sales, operating income and cash conversion and each accounted for one third of the total performance matching shares The table below shows the performance targets for the only open EPSP from 2016 as of December 31, 2019. Executive Performance Stock Plan targets Base year value SEK billion Year 1 Year 2 Year 3 2016 Compound annual growth rate of Growth (net sales growth) 246.9 2%–6% Margin Compound annual growth rate of (operating income growth) 1) 24.8 5%–15% Cash flow (cash conversion) — ≥70% ≥70% ≥70% 1) Excluding extraordinary restructuring charges. With all three years of 2016 EPSP completed the Board of Directors resolved the results of the performance targets as below: – Growth (compound annual net sales growth rate) was –5.13% which was below the threshold and resulted in no vesting for the portion of the award subject to this target. – Margin (compound annual operating income growth rate) was –28.00% which was below the threshold and resulted in no vesting for the portion of the award subject to this target. – Cash flow (cash conversion) was met, which resulted in vesting of 66.67% of the portion of the award subject to this target. Note G3, cont’d. – Accordingly, the 2016 EPSP vested at 22.22% of maximum matching. Since no SPP was proposed after 2016, the share-based LTV were introduced for the members of the ET with the approval of relevant AGM replacing EPSP. For the senior managers, the cash-based EPP were introduced replacing EPSP. The LTV and the EPP are described above. EPSP was a share-settled stock purchase plan with performance conditions. The total cost for EPSP for the three years of service is based on the number of shares that vest, due to fulfillment of targets and savings. The costs are calculated based on the FV of the shares as defined at grant date. Maximum Outstanding Matching Rights The table below shows the maximum outstanding matching rights for the President and CEO and the other members of the ET under the only currently open SPP and EPSP from 2016 as of December 31, 2019. Maximum outstanding matching rights As of December 31, 2019 The President Other members Number of Class B shares and CEO of the ET Stock Purchase Plans 2016 Executive Performance Stock Plans 2016 — 40,650 Comments to the table – For the definition of matching rights, see the descriptions in sections “The Stock Purchase Plan (SPP)”, “The Key Contributor Retention Plan” and “The Executive Performance Stock Plan (EPSP)”. – Vesting result of 22.22% of maximum matching is included for the 2016 EPSP. – During 2019, no matching shares were received by President and CEO since Börje Ekholm is not entitled for 2016 SPP and 2016 EPSP. – During 2019, other members of the ET received 59,845 matching shares.

For the other ongoing plans, cost is estimated. 2) Fair value is calculated as the share price on the investment date, reduced by the net present value of the dividend expectations during the three-year vesting period. Net present value calculations are based on data from external party. 3 ) Total compensation costs charged during 2018: SEK 645 million, 2017: SEK 876 million. Shares for LTV 2015–2016 and LTV 2017 LTV 2015–2016 and LTV 2017 are funded with treasury stock and are equity settled. Treasury stock for all plans has been issued in directed cash issues of Class C shares at the quotient value and purchased under a public offering at the subscription price plus a premium corresponding to the subscribers’ financing costs, and then converted to Class B shares. For all these plans, additional shares have been allocated for financing of social security expenses. Treasury stock is sold on the Nasdaq Stockholm to cover social security payments when arising due to matching/vesting of shares. During 2019, 2,278,800 shares were sold at an average price of SEK 86.59. Sales of shares are recognized directly in equity. If, as of December 31, 2019, all shares allocated for future matching/vesting under the Stock Purchase Plan were transferred, and shares designated to cover social security payments were disposed of as a result of the exercise and the matching/vesting, approximately 13 million Class B shares would be transferred, corresponding to 0.4% of the total number of shares outstanding, 3,314 million shares not including treasury stock. As of December 31, 2019, approximately 20 million Class B shares were held as treasury stock. The table above shows how shares (representing matching rights but excluding shares for social security expenses) are being used for all outstanding stock purchase plans, key contributor retention plans and executive performance stock plans. From up to down the table includes (A) the number of shares originally approved at the Annual General Meeting; (B) the number of originally designated shares that were outstanding at the beginning of 2019; (C) the number of shares awarded during 2019; (D) the number of shares matched during 2019; (E) the number of shares forfeited by participants or expired under the plan rules during 2019; and (F) the balance left as outstanding at the end of 2019, having deducted the shares related to awards matched, forfeited and expired, to the shares outstanding at the beginning of the year. The final row (G) shows the compensation costs charged to the accounts during 2019 for each plan. Option agreements Prior to taking office as President and CEO of Ericsson, Board member Börje Ekholm entered into an option agreement in 2016 with Investor AB and AB Industrivärden, shareholders of Ericsson. Each of these two shareholders has issued 1,000,000 call options to Börje Ekholm on market terms (valuation conducted, using the Black & Scholes model, by an independent third party). Under the agreements, Börje Ekholm has purchased in total 2,000,000 call options, issued by the shareholders, for a purchase price of SEK 0.49 per call option. Each call option entitles the purchase of one Ericsson B share from the shareholders at a strike price of SEK 80 per share (to be recalculated to neutralize the effects of dividend payments during the option period) during one year after a seven-year period. Due to the fact that the call options were purchased on market terms as described above, no compensation expense has been recognized by the Company and will not be recognized during the remaining part of the seven-year period. In 2019 Investor AB, shareholder of Ericsson, made an offer to the Board Chairs of its listed core investment to purchase call options relating to shares in the respective core investment. Following this offer, Ronnie Leten, Chair of the Board of Directors, entered into such a call option agreement with Investor AB with respect to Class B share of Telefonaktiebolaget LM Ericsson. Under the agreement, Investor AB has issued 128,452 call options to Ronnie Leten on market terms (valuation conducted, using the Black & Scholes model, by an independent third party) and Ronnie Leten has purchased these call options for a purchase price of SEK 15.57 per call option. Each call option entitles the purchase of one Ericsson B share from Investor AB at a strike price of SEK 87.97 per share (to be recalculated to neutralize the effects of dividend payments during the option period) during one year after a four-year period starting February 5, 2019. Due to the fact that the call options were purchased on market terms as described above, no compensation expense has been recognized by the Company and will not be recognized during the remaining part of the period.

Major Components Of Tax Expense Income [Abstract]
H1 Taxes	H1 The Company’s tax expense for 2019 was SEK –6,922 (–4,813) million or 79,0% (–329.1%) of income after financial items. The tax rate may vary between years depending on business and geographical mix. Items reported for income taxes include a reasonable estimate of the impact of the material aspects of the Swedish tax rate reduction which was signed into law on June 14, 2018, on the deferred tax assets and liabilities. The law reduces the corporate income tax from 22% to 21.4% from January 1, 2019, and to 20.6% from January 1, 2021. Income taxes recognized in the income statement 2019 2018 2017 Current income taxes for the year (2,564) (5,513) (4,168) Current income taxes related to prior years (2,237) (392) 83 Deferred tax income/expense (+/–) (2,116) 1,097 7,613 Share of taxes in joint ventures and associated companies (5) (5) (3) Tax expense/benefit (6,922) (4,813) 3,525 A reconciliation between reported tax expense for the year and the theoretical tax expense that would arise when applying statutory tax rate in Sweden, 21.4%, on the consolidated income before taxes, is shown in the table below. The Company has implemented IFRIC 23, which requires quarterly assessments of uncertain tax positions. Prior year tax adjustment includes uncertain tax position considerations. Tax effects of non-deductible expenses includes the effect of the SEC and DOJ payment.

Deferred tax assets are only recognized in countries where the Company expects to be able to generate corresponding taxable income in the future to benefit from tax reductions. Deferred tax assets and liabilities have been adjusted for the effect of the reduction of the Swedish corporate income tax rate. Note H1, cont’d. Tax loss carry-forwards Significant tax assets regarding tax loss carry-forwards are reported to the extent that realization of the related tax benefit through future taxable profits is probable also when considering the period during which these can be utilized, as describe below. The majority of tax loss carry-forwards pertains to Sweden, the US and Germany. These countries have long or indefinite periods of utilization. Of the total SEK 7,221 (8,449) million recognized deferred tax assets related to tax loss carry-forwards, SEK 6,026 (7,006) million relates to Sweden. Future income projections based on growth coming from a stronger market, selective market share gains and expansion of the product portfolio, support the conclusion that the deferred tax assets will be utilized in the foreseeable future. As of December 31, 2019, the recognized tax loss carry-forwards amounted to SEK 33,744 (39,415) million. The reduction is primarily attributable to utilization of the loss carry-forward against current year’s taxable income. The tax value of the tax loss carry-forward is reported as a tax asset based on the indefinite utilization period and the expectation that the group will realize a significant taxable income to offset these loss carry-forwards. The final years in which the recognized tax loss carry-forwards can be utilized are shown in the following table. Tax loss carry-forwards Year of expiration Tax loss carry-forwards Tax value 2020 94 29 2021 177 44 2022 320 95 2023 32 7 2024 155 45 2025 or later 32,966 7,001 Total 33,744 7,221 In addition to the table above there are tax loss carry-forwards of SEK 5,378 (4,223) million at a tax value of SEK 1,009 (773) million that have not been recognized due to judgments of the possibility they will be used against future taxable profits in the respective jurisdictions. The majority of these tax loss carry-forwards have an expiration date in excess of five years.

H6 Events after the reporting period	H6 US Securities class action On January 11, 2020, the United States District Court for the Southern District of New York granted Ericsson’s motion to dismiss the putative class action filed in 2018 against Telefonaktiebolaget LM Ericsson, the present President and CEO and the Chief Financial Officer of Ericsson as well as three former executives. At the same time the court granted plaintiffs leave to file a third amended complaint within thirty days. The plaintiffs did not file an amended complaint by the court-ordered deadline. Sol IP Settlement Ericsson has after the year-end 2019 resolved the previously communicated litigation with Sol IP, concerning alleged infringement of 20 patents declared to the LTE standard. The patents originated from Electronics and Telecommunications Research Institute (ETRI), a Korean government-funded research institution. The settlement resolves the litigation with Sol IP and involves a patent license agreement between Ericsson, Sol IP and ETRI. The settlement will have a negative impact for 2020 of approximately USD 13 million on operating income within Segment Networks of which USD 10 million will be recorded in Q1 2020 and the balance spread equally over the remaining quarters. This quarterly license fee amortization will continue in subsequent periods. The exact terms of the agreement are confidential. For more information, see note D2, “Contingent liabilities.” Ericsson to acquire Genaker to strengthen Mission Critical Push-to-talk offering On March 12, 2020, Ericsson announced that it had signed an agreement to acquire 100 percent of the shares in Genaker, a provider of Mission Critical Push-to-talk (MC-PTT) solutions. The acquisition strengthens Ericsson’s MC-PTT offering as the mission critical communications and private network market is going through a significant technology shift. Genaker, located in Barcelona, Spain, was founded in 2004 and employs around 30 people, all of whom will transfer to Ericsson as part of the acquisition. Pandemics, such as for example the one caused by the Coronavirus, COVID-19, could severely impact our local and global operations Pandemics, such as for example the one caused by the Coronavirus, could severely impact our local and global operations related to e.g. Service Delivery, Research & Development, Sales and Supply, as well as our customers and suppliers, with significant financial and other consequences. As an example, the Coronavirus has caused disturbance to our operations in China where Ericsson has offices and manufacturing sites. It is starting to cause similar disruptions to Ericsson’s operations and those of its customers and suppliers in other countries and to negatively impact the global economy. The effects of those disruptions may have material adverse effects on our business and financial position.

Summary Of Significant Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The financial statements are presented in millions of Swedish Krona (SEK). They are prepared on a historical cost basis, except for certain financial assets and liabilities that are stated at fair value: financial instruments classified as fair value through profit and loss (FVTPL), financial instruments classified as fair value through other comprehensive income (FVOCI) and plan assets related to defined benefit pension plans. Financial information in the consolidated income statement, the consolidated statement of comprehensive income, the consolidated statement of cash flows and the consolidated statement of changes in equity with related notes are presented with two comparison years. For the consolidated balance sheet, financial information with related notes is presented with two comparison year.
Basis of consolidation and composition of the Group	Basis of consolidation and composition of the Group The consolidated financial statements are prepared in accordance with the purchase method. Accordingly, consolidated stockholders’ equity includes equity in subsidiaries, joint ventures and associated companies earned only after their acquisition. Subsidiaries are all companies for which Telefonaktiebolaget LM Ericsson, directly or indirectly, is the parent. To be classified as a parent, Telefonaktiebolaget LM Ericsson, directly or indirectly, must control another company which requires that the Parent Company has power over that other company, is exposed to variable returns from its involvement and has the ability to use its power over that other company. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that such control ceases. Intra-group balances and any unrealized income and expense arising from intra-group transactions are fully eliminated in preparing the consolidated financial statements. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. The Company is composed of a parent company, Telefonaktiebolaget LM Ericsson, with generally fully-owned subsidiaries in many countries of the world. The largest operating subsidiaries are the fully-owned telecom vendor companies Ericsson AB, incorporated in Sweden and Ericsson Inc., incorporated in the US.
Foreign currency remeasurement and translation	Foreign currency remeasurement and translation Items included in the financial statements of each entity of the Company are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in Swedish Krona (SEK), which is the Parent Company’s functional and presentation currency.
Transactions and balances	Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of each respective transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement. Changes in the fair value of monetary securities denominated in foreign currency classified as fair value through other comprehensive income (FVOCI) are allocated between translation differences resulting from changes in the amortized cost of the security and other changes in the carrying amount of the security. Translation differences related to changes in the amortized cost are recognized in profit or loss, and other changes in the carrying amount are recognized in Other Comprehensive Income (OCI). Translation differences on monetary financial assets and liabilities are reported as part of the fair value gain or loss. From 2019, in order to reflect the way the Company manages its foreign exchange risks on a net basis, foreign exchange effect is presented as a net item within Financial Income and Expenses, reported separately from other financial income and expenses items. Previously foreign exchange effects were reported within both Financial Income and Financial Expense depending on whether they were related to assets or liabilities. Note F2, “Financial income and expenses” has been restated to reflect the change.
Group companies	Group companies The results and financial position of all the group entities that have a functional currency different from the presentation currency are translated into the presentation currency as follows: Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet. Period income and expenses for each income statement are translated at period average exchange rates. All resulting net exchange differences are recognized as a separate component of Other comprehensive income (OCI). On consolidation, exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are accounted for in OCI. When a foreign operation is disposed of or sold, exchange differences that were recorded in OCI are recognized in the income statement as part of the gain or loss on sale. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and are translated at the closing rate. The Company is continuously monitoring the economies with high inflation, the risk of hyperinflation and potential impact on the Company. There is no significant impact due to any currency translation of a hyper-inflationary economy.
Revenue recognition	Revenue recognition IFRS 15, “Revenue from Contracts with Customers” is a principle-based model of recognizing revenue from customer contracts. It has a five-step model that requires revenue to be recognized when control over goods and services are transferred to the customer. The following paragraphs describes the types of contracts, when performance obligations are satisfied, and the timing of revenue recognition. They also describe the normal payment terms associated with such contracts and the resulting impact on the balance sheet over the duration of the contracts. The vast majority of Ericsson’s business is for the sale of standard products and services.
Standard products and services	Standard products and services Products and services are classified as standard solutions if they do not require significant installation and integration services to be delivered. Installation and integration services are generally completed within a short period of time, from the delivery of the related products. These products and services are viewed as separate distinct performance obligations. This type of customer contract is usually signed as a frame agreement and the customer issues individual purchase orders to commit to purchases of products and services over the duration of the agreement. Note A1, cont’d. Revenue for standard products is recognized when control over the equipment is transferred to the customer at a point in time. This assessment shall be viewed from a customer’s perspective considering indicators such as transfer of titles and risks, customer acceptance, physical possession, and billing rights. For hardware sales, transfer of control is usually deemed to occur when the equipment arrives at the customer site and for software sales, when the licenses are made available to the customer. Software licenses may be provided to the customer at a point in time, activated or ready to be activated by the customer at a later stage, therefore revenue is recognized when customer obtains control of the software. Contractual terms may vary, therefore judgment will be applied when assessing the indicators of transfer of control for both hardware and software sales. Software licenses are also sold on a when-and-if available basis or delivered to the customer network over a period of time. In such cases, the customer is billed on a subscription basis or based on usage, and revenue is recognized over time. Revenue for installation and integration services is recognized upon completion of the service. Costs incurred in delivering standard products and services are recognized as costs of sales when the related revenue is recognized in the Income statement. Costs incurred relating to performance obligations not yet fully delivered are recognized as Inventories. Transaction prices under these contracts are usually fixed, and mostly billed upon delivery of the hardware or software, or completion of installation services. A proportion of the transaction price may be billed upon formal acceptance of the related installation services, which will result in a contract asset for the proportion of the transaction price that is not yet billed. Amounts billed are normally subject to payments terms within 60 days from invoice date. Customer finance agreements may be agreed separately with some customers where payment terms exceed 179 days. Revenue for recurring services such as customer support and managed services is recognized as the services are delivered, generally pro-rata over time. Costs incurred in delivering recurring services are recognized as cost of sales as they are incurred. Transaction prices under these contracts are billed over time, often on a quarterly basis. Transaction price for managed services contract may include variable consideration that is estimated based on performance and prior experience with the customer. Amounts billed are normally subject to payments terms within 60 days from invoice date. Contract liabilities or receivables may arise depending on whether the quarterly billing is in advance or in arrears. Contracts for standard products and services apply to business in all segments.
Customized solution	Customized solution Some products and services are sold together as part of a customized solution to the customer. This type of contract requires significant installation and integration services to be delivered within the solution, normally over a period of more than one year. These products and services are viewed together as a combined performance obligation. This type of contract is usually sold as a firm contract in which the scope of the solution and obligations of both parties are clearly defined for the duration of the contract. Customized solution does not have any alternative use to the Company as it cannot be sold to or used by other customers. Revenue for the combined performance obligation shall be recognized over time if progress of completion can be reliably measured and enforceable right to payment exists over the duration of the contract. The progress of completion is estimated by reference to the output delivered such as achievement of contract milestones and customer acceptance. This method determines revenue milestones over the duration of the contract, and it is considered appropriate as it reflects the nature of the customized solution and how integration service is delivered in these projects. If the criteria above are not met, then all revenue shall be recognized upon the completion of the customized solution, when final acceptance is provided by the customer. Costs incurred in delivering customized solutions are recognized as costs of sales when the related revenue milestone is recognized in the Income statement. Costs incurred relating to future revenue milestones are recognized as Inventories and assessed for recoverability on a regular basis. Transaction price under these contracts is usually a fixed fee, split into a number of progress payments or billing milestones as defined in the contract. In most cases, revenue recognized is limited to the progress payments or unconditional billing milestones over the duration of the contract, therefore no contract asset or contract liability arises on these contracts. In some contracts, revenue may be recognized in advance of billing milestones if enforceable payment rights exist at all times over the contract duration. This will result in an unbilled receivable balance until billing milestones are reached. Amounts billed are normally subject to payments terms within 60 days from invoice date. Customer finance agreements may be agreed separately with some customers where payment terms exceed 179 days. Contract for customized solution applies to the Business Support Systems (BSS) business within the segment Digital Services.
Intellectual Property Rights (IPR)	Intellectual Property Rights (IPR) This type of contract relates to the patent and licensing business. The Company has assessed that the nature of its IPR contracts is such that they provide customers a license with the right to access the Company intellectual properties over time, therefore revenue shall be recognized over the duration of the contract. Royalty revenue based on sales or usage is recognized when the sales and usage occur. The transaction price on these contracts is usually structured as a royalty fee based on sales or usage over the period, measured on a quarterly basis. This results in a receivable balance if the billing is performed the following quarter after measurement. Some contracts include lump sum amounts, payable either up front at commencement or on an annual basis. This results in a contract liability balance if payment is in advance of revenue, as revenue is recognized over time. Amounts billed are normally subject to payments terms within 60 days from invoice date. As described in note B1 “Segment Information”, revenue from IPR licensing contracts are allocated to the segments Networks and Digital Services.
Customer contract related balances	Customer contract related balances Trade receivables include amounts that have been billed in accordance with customer contract terms and amounts that the Company has an unconditional right to, with only passage of time before the amounts can be billed in accordance with the customer contract terms. Customer finance credits arise from credit terms exceeding 179 days in the customer contract or a separate financing agreement signed with the customer. Customer finance is a class of financial assets that is managed separately from receivables. See note F1, “Financial risk management,” for further information on credit risk management of trade receivables and customer finance credits. In accordance with IFRS 15, where significant financing is provided to the customer, revenue is adjusted to reflect the impact of the financing transaction. These transactions could arise from the customer finance credits above if the contracted interest rate is below the market rate or through implied financing transactions due to payment terms of more than one year from the date of transfer of control. The Company has elected to use the practical expedient not to adjust revenue for transactions with payment terms, measured from the date of transfer of control, of one year or less. Contract asset is unbilled sales amount relating to performance obligation that has been satisfied under customer contract but is conditional on terms other than only the passage of time before payment of the consideration is due. Under previous standards these unbilled sales balances have been included within trade receivables. Contract liability relates to amounts that are paid by or due from customers for which performance obligations are unsatisfied or partially satisfied. Under previous standards these balances have been disclosed as deferred revenue within other current liabilities, and the Company concluded that the balances meet the definition of contract liability under IFRS 15. Advances from customers are also included in the contract liability balance.
Segment reporting	Segment reporting An operating segment is a component of a company whose operating results are regularly reviewed by the Company’s chief operating decision maker, (CODM), to make decisions about resources to be allocated to the segment and assess its performance. The President and the CEO is defined as the CODM function in the Company. The segment presentation, as per each segment, is based on the Company’s accounting policies as disclosed in this note. The Company’s segment disclosure about geographical areas is based on the country in which transfer of risks and rewards occur. For further information, see note B1, “Segment information.”
Inventories	Inventories Inventories are measured at the lower of cost or net realizable value on a first-in, first-out (FIFO) basis. Risks of obsolescence have been measured by estimating market value based on future customer demand and changes in technology and customer acceptance of new products. A significant part of Inventories is Contract work in progress (CWIP). Recognition and derecognition of CWIP relates to the Company’s revenue recognition principles meaning that costs incurred under a customer contract are initially recognized as CWIP (see Revenue recognition policy). When the related revenue is recognized, CWIP is derecognized and is instead recognized as Cost of sales. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Trade payables	Trade payables See accounting policies under the subheading for Financial instruments and risk management. Trade payables Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.
Goodwill	Goodwill As from the acquisition date, goodwill acquired in a business combination is allocated to each cash-generating unit (CGU) of the Company expected to benefit from the synergies of the combination. An annual impairment test for the CGUs to which goodwill has been allocated is performed in the fourth quarter, or when there is an indication of impairment. An impairment loss is recognized if the carrying amount of an asset or its cash-generating unit exceeds its recoverable amount. The recoverable amount is the higher of the value in use and the fair value less costs of disposal. In assessing value in use, the estimated future cash flows after tax are discounted to their present value using an after-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Application of after-tax amounts in calculation, both in relation to cash flows and discount rate is applied due to that available models for calculating discount rate include a tax component. The after-tax discount rate applied by the Company is not materially different from a discounting based on before-tax future cash flows and before-tax discount rates, as required by IFRS. An impairment loss in respect of goodwill is not reversed. Write-downs of goodwill are reported under other operating expenses. As a result of the application of IFRS 16 the impairment test has been modified to include also right-of-use assets in the carrying value but not lease liabilities. Additional disclosure is required in relation to goodwill impairment testing: see note A2, “Critical accounting estimates and judgments” below and note C1, “Intangible assets.”
Intangible assets and other than goodwill	Intangible assets and other than goodwill Intangible assets other than goodwill comprise intangible assets acquired through business combinations, such as patents, customer relations, trademarks and software, as well as capitalized development expenses and separately acquired intangible assets, mainly consisting of software. At initial recognition, acquired intangible assets related to business combinations are stated at fair value and capitalized development expenses and software are stated at cost. Subsequent to initial recognition, these intangible assets are stated at initially recognized amounts less accumulated amortization and any impairment. Amortization and any impairment losses are included in Research and development expenses, which mainly consists of capitalized development expenses and technology; in Selling and administrative expenses, which mainly consists of expenses relating to customer relations and brands; and in Cost of sales. Costs incurred for development of products to be sold, leased, or otherwise marketed or intended for internal use are capitalized as from when technological and economic feasibility has been established until the product is available for sale or use. Research and development expenses directly related to orders from customers are accounted for as a part of Cost of sales. Other research and development expenses are charged to income as incurred. Amortization of acquired intangible assets, such as patents, customer relations, trademarks, and software, is made according to the straight-line method over their estimated useful lives, not exceeding ten years. The Company has not recognized any intangible assets with indefinite useful life other than goodwill. Impairment tests are performed whenever there is an indication of impairment. Tests are performed in the same way as for goodwill, see above. However, intangible assets not yet available for use are tested annually. Corporate assets have been allocated to cash-generating units in relation to each unit’s proportion of total net sales. The amount related to corporate assets is not significant. Impairment losses recognized in prior periods are assessed at each reporting date for any indications that the loss has decreased or no longer exists. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Property, plant, and equipment	Property, plant, and equipment Property, plant, and equipment consist of real estate, machinery, servers and other technical assets, other equipment, tools and installation and construction in process. They are stated at cost less accumulated depreciation and any impairment losses. Depreciation is charged to income, on a straight-line basis, over the estimated useful life of each component of an item of property, plant, and equipment, including buildings. Estimated useful lives are, in general, 25–50 years for real estate and 3–10 years for machinery and equipment. Depreciation and any impairment charges are included in Cost of sales, Research and development or Selling and administrative expenses. The Company recognizes in the carrying amount of an item of property, plant, and equipment the cost of replacing a component and derecognizes the residual value of the replaced component. Impairment testing as well as recognition or reversal of impairment of property, plant and equipment is performed in the same manner as for intangible assets other than goodwill, see description under “Intangible assets other than goodwill” above. Gains and losses on disposals are determined by comparing the proceeds less cost to sell with the carrying amount and are recognized within Other operating income and expenses in the income statement.
Leasing	Leasing The main types of assets leased by the Company are, in the order of materiality, real estate, IT-equipment and vehicles. Vehicles are mainly used under service contracts. Accounting policies applied as of January 2019 - IFRS 16 Leases Leasing when the Company is the lessee The Company recognizes right-of-use assets and lease liabilities arising from all leases in the balance sheet, with some exceptions. This model reflects that, at the start of a lease, the lessee always obtains the right to use an asset for a period of time and has an obligation to pay for that right. In the assessment of a lease contract the lease components are separated from non-lease components and the lease term is defined based on the contract lease term and when reasonably certain estimated extension or termination options are included. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted normally using the Company’s incremental borrowing rate. The incremental borrowing rate is calculated considering interest swap rates, the credit spread on bonds issued by real estate companies and the creditworthiness of the entity that signs the lease. Lease payments included in the liability are fixed payments, variable payments depending on an index or rate, residual values and penalties for termination of contracts. The right-of-use asset is initially measured at cost, which equals the amount of the initial measurement of lease liability adjusted for any lease payments made at or before the commencement date less any lease incentives received plus any initial direct costs, and restoration costs. The Company applies the recognition exemption for short-term leases and leases for which the underlying asset is of low-value recognizing the lease payments for those leases as an expense on a straight-line basis over the lease term. The interest expense on lease liabilities is presented as a component of finance costs separate from the depreciation charges for right-of-use assets. In the statement of cash flows, cash payments for the principal portion of the lease liability is reported within financing activities while payments for short-term leases, low-value assets and variable lease expenses not included in the measurement of the lease liability are classified within operating activities. For more information regarding leasing see note C3, “Leases.” Leasing when the Company is the lessor Leasing contracts with the Company as lessor are classified as finance leases when the majority of risks and rewards are transferred to the lessee, and otherwise as operating leases. Under a finance lease, a receivable is recognized at an amount equal to the net investment in the lease and revenue is recognized in accordance with the revenue recognition principles. Under operating leases the equipment is recorded as property, plant and equipment and revenue as well as depreciation is recognized on a straight-line basis over the lease term. Accounting policies applied prior to 2019 Prior to 2019, IAS 17 was applied instead of IFRS 16. Comparative information has not been restated. The following accounting policies apply to periods prior to 2019. Leasing when the company was the lessee Leases on terms in which the Company assumed substantially all the risks and rewards of ownership were classified as finance leases. Upon initial recognition, the leased asset was measured at an amount equal to the lower of its fair value and the present value of the minimum lease payments. Subsequent to initial recognition, the asset was accounted for in accordance with the accounting policy applicable to that type of asset, although the depreciation period did not exceed the lease term. Note A1, cont’d. Other leases were operating leases, and the leased assets under such contracts were not recognized on the balance sheet. Costs under operating leases were recognized in the income statement on a straight-line basis over the term of the lease. Lease incentives received were recognized as an integral part of the total lease expense, over the term of the lease. Leasing when the Company was the lessor Leasing contracts with the Company as lessor were classified as finance leases when the majority of risks and rewards were transferred to the lessee, and otherwise as operating leases. Under a finance lease, a receivable was recognized at an amount equal to the net investment in the lease and revenue was recognized in accordance with the revenue recognition principles. Under operating leases the equipment was recorded as property, plant and equipment and revenue as well as depreciation was recognized on a straight-line basis over the lease term.
Provisions	Provisions Provisions are made when there are legal or constructive obligations as a result of past events and when it is probable that an outflow of resources will be required to settle the obligations and the amounts can be reliably estimated. When the effect of the time value of money is material, discounting is made of estimated outflows. However, the actual outflows as a result of the obligations may differ from such estimates. The provisions are mainly related to restructuring, customer and supplier related provisions, warranty commitments and other obligations, claims or obligations as a result of patent infringement and other litigations and customer finance guarantees. Product warranty commitments consider probabilities of all material quality issues based on historical performance for established products and expected performance for new products, estimates of repair cost per unit, and volumes sold still under warranty up to the reporting date. A restructuring obligation is considered to have arisen when the Company has a detailed formal plan for the restructuring (approved by management), which has been communicated in such a way that a valid expectation has been raised among those affected. Provision for restructuring is recorded when the Company can reliably estimate the liabilities relating to the obligation. Customer contract provisions mainly consist of estimated losses on onerous contracts. For losses on customer contracts, a provision equal to the total estimated loss is recorded immediately when a loss from a contract is probable and can be estimated reliably. These contract loss estimates may include penalties under a loss contract. Other provisions include provisions for obligations related to cash-settled share-based programs, litigations and other provisions. The Company provides for estimated future settlements related to patent infringements based on the probable outcome of each infringement. The actual outcome or actual cost of settling an individual infringement may vary from the Company’s estimate. The Company estimates the outcome of any potential patent infringement made known to the Company through assertion and through the Company’s own monitoring of patent-related cases in the relevant legal systems. To the extent that the Company makes the judgment that an identified potential infringement will more likely than not result in an outflow of resources, the Company records a provision based on the Company’s best estimate of the expenditure required to settle with the counterpart. In the ordinary course of business, the Company is subject to proceedings, lawsuits and other unresolved claims, including proceedings under laws and government regulations and other matters. These matters are often resolved over a long period of time. The Company regularly assesses the likelihood of any adverse judgments in or outcomes of these matters, as well as potential ranges of possible losses. Provisions are recognized when it is probable that an obligation has arisen and the amount can be reasonably estimated based on a detailed analysis of each individual issue.
Contingent liabilities	Contingent liabilities Certain present obligations are not recognized as provisions as it is not probable that an economic outflow will be required to settle the obligations or the amount of the obligation cannot be measured with sufficient reliability. Such obligations are reported as contingent liabilities. For further detailed information, see note D2, “Contingent liabilities.” In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Business combinations	Business combinations At the acquisition of a business, the cost of the acquisition, being the purchase price, is measured as the fair value of the assets given, and liabilities incurred or assumed at the date of exchange, including any cost related to contingent consideration. Transaction costs attributable to the acquisition are expensed as incurred. The acquisition cost is allocated to acquired assets, liabilities and contingent liabilities based upon appraisals made, including assets and liabilities that were not recognized on the acquired entity’s balance sheet, for example intangible assets such as customer relations, brands, patents and financial liabilities. Goodwill arises when the purchase price exceeds the fair value of recognizable acquired net assets. In acquisitions with non-controlling interests full or partial goodwill can be recognized. Final amounts are established within one year after the transaction date at the latest. In case there is a put option for non-controlling interest in a subsidiary a corresponding financial liability is recognized.
Non-controlling interest	Non-controlling interest The Company treats transactions with non-controlling interests as transactions with equity owners of the Company. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity. When the Company ceases to have control, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest in an associate or financial asset. In addition, any amounts previously recognized in Other comprehensive income in respect of that entity are accounted for as if the Company had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in Other comprehensive income are reclassified to profit or loss. At acquisition, there is a choice on an acquisition-by-acquisition basis to measure the non-controlling interest in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets.
Joint ventures and associated companies	Joint ventures and associated companies Joint ventures and associated companies are accounted for in accordance with the equity method. Under the equity method, the investment in joint venture or associate is initially recognized at cost and the carrying amount is increased or decreased to recognize the investor’s share of the profit or loss of the investee after the date of acquisition. If the Company’s interest in an associated company is nil, the Company shall not, as prescribed by IFRS recognize its part of any future losses. Provisions related to obligations for such an interest shall, however, be recognized in relation to such an interest. Investments in associated companies, i.e., when the Company has significant influence and the power to participate in the financial and operating policy decisions of the associated company but is not in control or joint control over those policies. Normally, this is the case in voting stock interest, including effective potential voting rights, which stand at least at 20% but not more than 50%. The Company’s share of income before taxes is reported in item “Share in earnings of joint ventures and associated companies,” included in Operating income. This reflects the fact that these interests are held for operating rather than investing or financial purposes. Ericsson’s share of income taxes related to associated companies is reported under the line item “Taxes,” in the income statement. Unrealized gains on transactions between the Company and its joint ventures and associated companies are eliminated to the extent of the Company’s interest in these entities. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Shares in earnings of joint ventures and associated companies included in consolidated equity which are undistributed are reported in Retained earnings in the balance sheet. Impairment testing as well as recognition or reversal of impairment of investments in each joint venture and associated company is performed in the same manner as for intangible assets other than goodwill. The entire carrying value of each investment, including goodwill, is tested as a single asset. See also description under “Intangible assets other than goodwill” below. If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in Other comprehensive income are reclassified to profit or loss where appropriate. In note A2, “Critical Accounting Estimates and Judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Financial assets	Financial assets Financial assets are recognized when the Company becomes a party to the contractual provisions of the instrument. Regular purchases and sales of financial assets are recognized on the settlement date. Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership. Separate assets or liabilities are recognized if any rights and obligations are created or retained in the transfer. The Company classifies its financial assets in the following categories: at amortized cost, at fair value through other comprehensive income (FVOCI), and at fair value through profit or loss (FVTPL). The classification depends on the characteristics of the asset and the business model in which it is held. Financial assets are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. The fair values of quoted financial investments and derivatives are based on quoted market prices or rates. If official rates or market prices are not available, fair values are calculated by discounting the expected future cash flows at prevailing interest rates. Valuations of foreign exchange options and Interest Rate Guarantees (IRG) are made by using the Black-Scholes formula. Inputs to the valuations are market prices for implied volatility, foreign exchange and interest rates.
Financial assets at amortized cost	Financial assets at amortized cost Financial assets are classified as amortized cost if the contractual terms give rise to payments that are solely payments of principal and interest on the principal amount outstanding and the financial asset is held in a business model whose objective is to hold financial assets in order to collect contractual cash flows. These assets are subsequently measured at amortized cost using the effective interest method, minus impairment allowances. Interest income and gains and losses from financial assets at amortized cost are recognized in financial income.
Financial assets at fair value through other comprehensive income	Financial assets at fair value through other comprehensive income (FVOCI) Assets are classified as FVOCI if the contractual terms give rise to payments that are solely payments of principal and interest on the principal amount outstanding and the financial asset is held in a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets. These assets are subsequently measured at fair value with changes in fair value recognized in other comprehensive income (OCI), except for effective interest, impairment gains and losses and foreign exchange gains and losses which are recognized in the income statement. Upon derecognition, the cumulative gain or loss in OCI is reclassified to the income statement.
Financial assets at fair value through profit or loss	Financial assets at fair value through profit or loss (FVTPL) All financial assets that are not classified as either amortized cost or FVOCI are classified as FVTPL. A financial asset is classified as held for trading if it is acquired principally for the purpose of selling in the near term. Derivatives are classified as held for trading, unless they are designated as hedging instruments for the purpose of hedge accounting. Assets held for trading are classified as current assets. Debt instruments classified as FVTPL, but not held for trading, are classified on the balance sheet based on their maturity date (i.e., those with a maturity longer than one year are classified as non-current). Investments in shares and participations are classified as FVTPL and classified as non-current financial assets. Gains or losses arising from changes in the fair values of the FVTPL category (excluding derivatives and customer financing) are presented in the income statement within financial income in the period in which they arise. Gains and losses on derivatives are presented in the income statement as follows. Gains and losses on derivatives that hedge operating assets or liabilities, financial assets and financial liabilities are presented as cost of sales, financial income and financial expense, respectively. Gains and losses on revaluation of customer financing are presented in the income statement as selling expenses. Dividends on equity instruments are recognized in the income statement as part of financial income when the Company’s right to receive payments is established.
Impairment in relation to financial assets	Impairment in relation to financial assets At each balance sheet date, financial assets classified as either amortized cost or FVOCI and contract assets are assessed for impairment based on Expected Credit Losses (ECL). ECLs are the difference between all contractual cash flows that are due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at the original effective interest rate. Allowances for trade receivables and contract assets are always equal to lifetime ECL. The Company has established a provision matrix based on historical credit loss experience, which has been adjusted for current conditions and expectations of future economic conditions. The losses are recognized in the income statement. When there is no reasonable expectation of collection, the asset is written off.
Financial liabilities	Financial liabilities Financial liabilities are recognized when the Company becomes bound to the contractual obligations of the instrument. Financial liabilities are derecognized when they are extinguished, i.e., when the obligation specified in the contract is discharged, cancelled or expired.
Borrowings	Borrowings Borrowings issued by the Parent Company are designated FVTPL because they are managed on a fair value basis. Changes in fair value are recognized in the income statement, except for changes in fair value due to changes in credit risk which are recognized in other comprehensive income. Borrowings not issued by the Parent Company are initially recognized at fair value, net of transaction costs incurred. These borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method. Borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date.
Financial guarantees	Financial guarantees Financial guarantee contracts are initially recognized at fair value (i.e., usually the fee received). Subsequently, these contracts are measured at the higher of: –– The expected credit losses. –– The recognized contractual fee less cumulative amortization when amortized over the guarantee period, using the straight-line-method.
Cash flow hedge accounting	Cash flow hedge accounting The company has identified certain customer contracts where a fluctuation in the USD/SEK foreign exchange (FX) rate would significantly impact net sales and operating income recorded from the contracts. These contracts are multi-year contracts denominated in USD with highly probable payments at fixed points in time. From first quarter 2019, the Company has entered into FX forward contracts that match the terms of the foreign exchange exposure as closely as possible and designated these as hedging instruments. At inception, the Company documents the economic relationship between the hedged item and hedging instrument. For FX hedges, the hedge ratio is usually 1:1. The Company will designate either changes in forward or spot rates as the hedged risk. When applying hedge accounting, the effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in OCI. The gain or loss relating to an ineffective portion is recognized immediately in Financial income and expenses, net. Upon recognition of the hedged net sales, the cumulative amount in cash flow hedge reserve is released in the OCI as a reclassification adjustment and recognized in net sales.
Accounting policies applied prior to 2018	Accounting policies applied prior to 2018 Prior to 2018, IAS 39 was applied instead of IFRS 9. Under IAS 39 the Company classified its financial assets in the following categories: at fair value through profit or loss, loans and receivables, and available-for-sale. The main differences in the effect on Income Statement under IAS 39 compared to IFRS 9 relate to the treatment of loans and receivables and available-for-sale assets. In 2017, borrowings were classified as amortized costs, however, parent company borrowings were hedged on fair value basis. These fair value hedges were discontinued by the end of 2017. Loans and receivables Receivables, including those that relate to customer financing, were subsequently measured at amortized cost using the effective interest rate method, less allowances for impairment charges. Available-for-sale financial assets Investments in liquid bonds with low credit risk which were not held for trading are classified as available-for-sale. Unrealized gains and losses were recognized in OCI. When these securities were derecognized, the accumulated fair value adjustments were included in financial income. Dividends on available-for-sale equity instruments were recognized in the income statement as part of financial income when the Company’s right to receive payments was established. Changes in the fair value of monetary securities denominated in a foreign currency and classified as available-for-sale were analyzed between translation differences resulting from changes in the amortized cost of the security and other changes in the carrying amount of the security. Translation differences on monetary securities were recognized in profit or loss; translation differences on non-monetary securities were recognized in OCI. Changes in the fair value of monetary and non-monetary securities classified as available-for-sale were recognized in OCI. When securities classified as available-for-sale were sold or impaired, the accumulated fair value adjustments previously recognized in OCI were included in the income statement. Impairment in relation to available-for-sale assets and loans and receivables At each balance sheet date, the Company assessed whether there was objective evidence that a financial asset or a group of financial assets was impaired. If any such evidence existed for available-for-sale financial assets, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognized in profit or loss – was removed from OCI and recognized in the income statement. Impairment losses recognized in the income statement on equity instruments were not reversed through the income statement. An assessment of impairment of receivables was performed when there was objective evidence that the Company would not be able to collect all amounts due according to the original terms of the receivable. The carrying amount of the asset was reduced through the use of an allowance account, and the amount of the loss was recognized in the income statement and presented as impairment losses on trade receivables within selling expenses. Borrowings Borrowings were initially recognized at fair value, net of transaction costs incurred. Borrowings were subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value was recognized in the income statement over the period of the borrowings using the effective interest method. Fair value hedging and fair value hedge accounting The Company only applied fair value hedge accounting for hedging fixed interest risk on parent company borrowings. The purpose of fair value hedges was to hedge the variability in the fair value of fixed-rate debt (issued bonds) from changes in the relevant benchmark yield curve for its entire term by converting fixed interest payments to a floating rate using interest rate swaps (IRS). The credit risk/ spread was not hedged. The fixed leg of the IRS was matched against the cash flows of the hedged bond. Hereby, the fixed-rate bond/debt was converted into a floating-rate debt in accordance with the policy. Both gains and losses relating to the interest rate swaps hedging fixed rate borrowings and the changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk were recognized in the income statement within Financial expenses. If the hedge no longer met the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method was used was amortized to the income statement over the remaining period to maturity. At the inception of the hedge, the Company documented the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. The Company also documented its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that were used in hedging transactions were highly effective in offsetting changes in fair values or cash flows of the hedged items.
Post-employment benefits	Post-employment benefits Pensions and other post-employment benefits are classified as either defined contribution plans or defined benefit plans. Under a defined contribution plan, the Company’s only obligation is to pay a fixed amount to a separate entity (a pension trust fund) with no obligation to pay further contributions if the fund does not hold sufficient assets to pay all employee benefits. The related actuarial and investment risks fall on the employee. The expenditures for defined contribution plans are recognized as expenses during the period when the employee provides service. Under a defined benefit plan, it is the Company’s obligation to provide agreed benefits to current and former employees. The related actuarial and investment risks fall on the Company. The present value of the defined benefit obligations for current and former employees is calculated using the Projected Unit Credit Method. The discount rate for each country is determined by reference to market yields on high-quality corporate bonds that have maturity dates approximating the terms of the Company’s obligations. In countries where there is no deep market in such bonds, the market yields on government bonds are used. The calculations are based upon actuarial assumptions, assessed on a quarterly basis, and are as a minimum prepared annually. Actuarial assumptions are the Company’s best estimate of the variables that determine the cost of providing the benefits. When using actuarial assumptions, it is possible that the actual results will differ from the estimated results or that the actuarial assumptions will change from one period to another. These differences are reported as actuarial gains and losses. They are, for example, caused by unexpectedly high or low rates of employee turnover, changed life expectancy, salary changes, remeasurement of plan assets and changes in the discount rate. Actuarial gains and losses are recognized in OCI in the period in which they occur. The Company’s net liability for each defined benefit plan consists of the present value of pension commitments less the fair value of plan assets and is recognized net on the balance sheet. When the result is a net benefit to the Company, the recognized asset is limited to the present value of any future refunds from the plan or reductions in future contributions to the plan. Interest cost on the defined benefit obligation and interest income on plan assets is calculated as a net interest amount by applying the discount rate to the net defined benefit liability. All past service costs are recognized immediately. Swedish special payroll tax is accounted for as a part of the pension cost and the pension liability respectively. Payroll taxes related to actuarial gains and losses are included in determining actuarial gains and losses, reported under OCI. In note A2, “Critical accounting estimates and judgments” further disclosure is presented in relation to key sources of estimation uncertainty.
Share-based compensation to employees and the Board of Directors	Share-based compensation to employees and the Board of Directors Share-based compensation is related to remuneration to employees, including key management personnel and the Board of Directors and could be settled either in shares or cash. Under IFRS, a company shall recognize compensation costs for share-based compensation programs based on a measure of the value to the company of services received under the plans. The conditions under a program shall be considered as prescribed in IFRS 2, “Share-based payment.” As from 2017 the newly granted share-based programs are cash-settled, except for programs for the Executive team. Those programs are share-settled. Share-settled plans Compensation costs are recognized during the vesting period, based on the fair value of the Ericsson share at the grant date, as well as considering performance – and market conditions. Examples of performance conditions could be revenue and profit targets while market conditions relate to the development of the Parent Company’s share price. The amount charged to the income statement for these plans is reversed in equity each time of the income statement charge. The reason for this IFRS accounting principle is that compensation cost for a share-settled program is a cost with no direct cash flow impact. All plans have service conditions and some of them have performance or market conditions. For further detailed information, see note G3, “Share-based compensation.” Note A1, cont’d. Cash settled plans The total compensation expense for a cash-settled plan is equal to the payments made to the employees at the date of end of the service period. The fair value of the synthetic shares, being the cash equivalents of shares, is therefore reassessed and amended during the service period. Otherwise the accounting is similar to a share-settled plan. For further detailed information, see note G3, “Share-based compensation.” Compensation to the Board of Directors During 2008, the Parent Company introduced a share-based compensation program as a part of the remuneration to the Board of Directors (a synthetic share program). The program gives non-employee Directors elected by the General Meeting of shareholders a right to receive part of their remuneration as a future payment of an amount which corresponds to the market value of a share of class B in the Parent Company at the time of payment, as further disclosed in note G3, “Share-based compensation.” The cost for cash-settlements is measured and recognized based on the estimated costs for the program on a pro rata basis during the service period, being one year. The estimated costs are remeasured during and at the end of the service period.
Income taxes	Income taxes Income taxes in the consolidated financial statements include both current and deferred taxes. Income taxes are reported in the income statement unless the underlying item is reported directly in equity or OCI. For those items, the related income tax is also reported directly in equity or OCI. A current tax liability or asset is recognized for the estimated taxes payable or refundable for the current year or prior years. Deferred tax is recognized for temporary differences between the book values of assets and liabilities and their tax values and for tax loss carry-forwards. A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the deductible temporary differences and tax loss carry-forwards can be utilized. In the recognition of income taxes, the Company offsets current tax receivables against current tax liabilities and deferred tax assets against deferred tax liabilities in the balance sheet, when the Company has a legal right to offset these items and the intention to do so. Deferred tax is not recognized for the following temporary differences: goodwill not deductible for tax purposes, for the initial recognition of assets or liabilities that affect neither accounting nor taxable profit and for differences related to investments in subsidiaries when it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is measured at the tax rate that is expected to be applied to the temporary differences when they reverse, based on the tax laws that have been enacted or substantively enacted by the reporting date. An adjustment of deferred tax asset/liability balances due to a change in the tax rate is recognized in the income statement, unless it relates to a temporary difference earlier recognized directly in equity or OCI, in which case the adjustment is also recognized in equity or OCI. As prescribed in IFRIC 23, uncertainty over income tax treatment is considered if and when recognizing and measuring income tax items in the financial statements. As a result of applying IFRS 16 “Leases,” the Company will not report deferred tax on initial recognition. The exemption in IAS 12 is applied i.e. no deferred tax is reported for the initial recognition of a right-of-use asset and a lease liability. Subsequently, analysis will be made of temporary differences to determine if changes are related to initial recognition or if new temporary differences have arisen and if deferred tax should be reported. The measurement of deferred tax assets involves judgment regarding the deductibility of costs not yet subject to taxation and estimates regarding sufficient future taxable income to enable utilization of unused tax losses in different tax jurisdictions. All deferred tax assets are subject to annual review of probable utilization. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Earnings per share	Earnings per share Basic earnings per share are calculated by dividing net income attributable to owners of the Parent Company by the weighted average number of shares outstanding (total number of shares less treasury stock) during the year. Diluted earnings per share are calculated by dividing net income attributable to owners of the Parent Company, when appropriately adjusted by the sum of the weighted average number of ordinary shares outstanding and dilutive potential ordinary shares. Potential ordinary shares are treated as dilutive when, and only when, their conversion to ordinary shares would decrease earnings per share. Rights to matching shares are considered dilutive when the actual fulfillment of any performance conditions as of the reporting date would give a right to ordinary shares.
Statement of cash flows	Statement of cash flows The statement of cash flows is prepared in accordance with the indirect method. Cash flows in foreign subsidiaries are translated at the average exchange rate during the period. Payments for subsidiaries acquired or divested are reported as cash flow from investing activities, net of cash and cash equivalents acquired or disposed of respectively. Cash and cash equivalents consist of cash, bank, and interest-bearing securities that are highly liquid monetary financial instruments with a remaining maturity of three months or less at the date of acquisition.
New accounting standards and interpretations	New accounting standards and interpretations A number of issued new standards, amendments to standards and interpretations are not yet effective for the year ended December 31, 2019 and have not been applied in preparing these consolidated financial statements.
