Summary Of Material Accounting Policies [Abstract]
A1 Material accounting policies	Material accounting policies 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 The consolidated financial statements for the year ended December 31, 2023, have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board ( ), The financial statements were approved by the Board of Directors on March 5, 2024. The financial statements are subject to approval by the Annual General Meeting of shareholders. Disclosure about new standards and amendments applied as from January 1, 2023, and the preparations for the adoption of new standards and interpretations not adopted in 2023 are disclosed at the end of this note, see heading Other. Basis of presentation The financial statements are presented in millions of Swedish Krona (SEK). They are prepared on a going concern and historical cost basis, except for certain financial assets and liabilities that are stated at fair value: financial instruments classified as fair value through profit or 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 one comparison year. Basis of consolidation and composition of the Group Subsidiaries are all companies for which Telefonaktiebolaget LM Ericsson, directly or indirectly, is the parent. To be classified as a parent, Telefonaktie-bolaget 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. The Company is comprised of the 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 transaction. For practical reason, the Company uses the closing rate of the previous month end as approximation of the prevailing rate at the date of transaction, although spot rate is used for material one-off transaction where appropriate. Foreign currency exchange effect is presented as a net item within Financial income and expenses, reported separately from other financial income and expenses items as this reflects the way the Company manages its foreign exchange risks on a net basis. Translations of 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. This includes goodwill arising on the acquisition of a foreign entity. Period income and expenses for each income statement are translated at period average exchange rates. For practical reason, the Company uses the closing rate of the previous month end as approximation of the period average exchange rates. All resulting net exchange differences are recognized as a separate component of Other comprehensive income (OCI), i.e. changes in translation reserves. The Company is continuously monitoring the economies with high inflation, the risk of hyperinflation and their Business and operations For further disclosure, see the notes under section B. Revenue recognition The following paragraphs describe 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. Standard products and services Products and services are classified as standard solutions as 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. For hardware sales, transfer of control and revenue recognition, is usually deemed to occur when the equipment arrives at the customer site. Standard product software is sold as an on-premises customer. Control is transferred when software licenses are provided to the customer at a point in time and already activated, or as a released software version, ready to be activated by the customer at a later stage. Revenue is recognized when control of the software is transferred and unconditional right to payment exists. Software licenses are also sold on a when-and-if Revenue for recurring services such as customer support and managed services is recognized as the services are delivered, pro-rata Enterprise solutions Enterprise solutions comprise mainly of software platform solutions, delivered as-a-service pro-rata Cloud services allow the customer to use hosted software over the contract period without taking possession of the software. Cloud services are highly integrated with the software and the individual components are not considered distinct, hence all revenue is recognized in the period these services are provided. Contract duration ranges from one month to 5 years. Revenue for fixed fee arrangement is recognized on a pro-rata Services sold through wholesalers or distributors are assessed for principal or agent relationship. Wholesalers are treated as agents for services that are activated upon delivery of equipment to the end users since the Company still has the primary responsibility to the customers for providing the services, hence revenue (in the gross amount) is recognized rateably from activation until the end of the contract. 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’s 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. Customer contract related balances Trade receivables include amounts that are 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. Prices on standard products and services 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. Standard recurring services contracts are billed over time, often on a quarterly basis. 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. For Enterprise solution fixed fee contracts, billing is typically in advance, resulting in contract liability. For usage-based contracts, billing is in arrears, resulting in a receivable. Typical credit term is 30 to 45 days. IPR contracts are upfront 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. 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. Where 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 over the duration of the financing period. Deferred sales commissions The Company has various incremental commission costs for internal sales personnel and channel partners that relate to the acquisition of customer contracts in the Enterprise segment. These costs are capitalized as deferred contract acquisition costs (within Other non-current Segment reporting The segment presentation, as per each segment, is based on the Company’s accounting policies as disclosed in this note. 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 Company’s segment disclosure about geographical areas is based on the country in which transfer of control of products and services occur. For further information, see note B1 “Segment information.” Inventories Inventories are measured at the lower of cost or net realizable value and using cost formula first-in, first-out 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. An inventory obsolescence provision is recognized as cost of sales in the income statement when identified. 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. 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) expected to benefit from the future 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 the value in use, the estimated future cash flows after tax are discounted to their present value using an after-tax after-tax calculating the discount rate include a tax component. The effect of after-tax before-tax before-tax Additional disclosure is required in relation to goodwill impairment testing: see note A2 “Critical accounting estimates and judgments” and note C1 “Intangible assets.” Intangible assets other than goodwill Intangible assets other than goodwill comprise Amortization is charged to the income statement, on a straight-line basis, over the estimated useful life of each intangible asset. Estimated useful lives for customer relationships acquired through the Vonage acquisition are 6 to 9 years. For other acquired intangible assets, such as patents, other customer relationships, trademarks, and software estimated useful lives do not exceed 10 years, and capitalized development expenses usually have a useful life of 3 years. Impairment tests are performed when there is an indication of impairment. Tests are performed in the same way as for goodwill but on an asset level, see above. However, intangible assets not yet available for use are tested annually for impairment. 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 and other technical assets, other equipment, tools and installations, and construction in progress. They are stated at cost less accumulated depreciation and any impairment losses. Depreciation is charged to the income statement 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, generally, 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. Gains and losses on disposals are reported within Other operating income and expenses in the income statement. Leases The main types of assets leased by the Company are, in order of materiality, real estate, vehicles and IT-equipment. Leases when the Company is the lessee The Company recognizes right-of-use non-lease At commencement date the lease liabilities are measured at the present value of the lease payments not paid at the commencement date, discounted using the Company’s incremental borrowing rate. The Group estimates its incremental borrowing rate to measure lease liabilities at the present value of lease payments as the interest rate implicit in the lease is not readily determinable. The incremental borrowing rate is calculated considering interest swap rates, the creditworthiness of the entity that signs the lease and an adjustment for the asset being collateralized. Lease payments included in the liability are fixed payments, variable payments depending on an index or rate and penalties for termination of contracts. The right-of-use on a basis expenses The Company applies the recognition exemption for short-term leases and leases for which the underlying asset is of low value and recognizes the lease payments for those leases as an expense on a straight-line basis over the lease term. When the Company acts as a lessor , Obligations For further disclosure, see the notes under section D. Provisions and Contingent Liabilities 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, the estimated cash flows are discounted to present value. However, the actual outflows as a result of the obligations may differ from such estimates. Provisions mainly relate to restructuring, customer and supplier-related provisions, warranty commitments, cash-settled share-based payments, claims or obligations as a result of patent infringement, and other litigations. 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. Curtailment gains and losses on defined benefit plans are reported as part of the net restructuring costs when the restructuring provision is raised for the underlying program. Customer-related 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. The loss is calculated based on the lower of the unavoidable costs to fulfill a contract and the exit penalty. The unavoidable cost includes both the incremental and allocated costs to fulfill the contract. Supplier-related provisions relate to contractual commitments mostly relating to inventories. The provision is based on a risk assessment comparing the forecasted sales volumes with the committed inventory levels. If the contractually committed inventory is assessed to be at risk of not being met, a provision is raised equal to the best estimate of the expected obsolescence or the contractual fee. 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. Share-based payment provision relates to cash-settled share-based programs. Refer to the accounting policy under “Cash-settled plans.” Other provisions relate mainly to patent infringements, litigations, and other provisions which do not fall within the defined categories. 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 the Company’s monitoring of patent-related cases in the relevant legal systems. In the ordinary course of business, the Company is subject to proceedings, lawsuits, and other unresolved claims. 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. Present or possible obligations that do not meet the provision recognition criteria 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. Group structure For further disclosure, see the notes under section E. 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 acquired acquisition-by-acquisition non-controlling non-controlling The acquired entity is consolidated into the Group results from the date of acquisition. Accordingly, the consolidated stockholders’ equity includes equity in subsidiaries, joint ventures, and associated companies earned only after their acquisition. Associated companies Investments in associated companies is when the Company has significant influence and the ability 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%. Associated companies are accounted for in accordance with the equity method. Any change in other comprehensive income of the associated companies is presented as part of other comprehensive income. If the Company’s interest in an associated company is nil, the Company does not recognize its part of any future losses. Provisions related to obligations for such an interest are recognized. Financial instruments and risk management For further disclosure, see the notes under section F. Plan assets under IAS 19 are excluded from the financial risk management policy and financial instruments disclosures in section F. 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 securities are recognized on the settlement date. Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership. The Company sells its receivables with the expectation that all derecognition criteria are fully satisfied thereby no material asset or liability is retained. 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 cash flow characteristics of the asset and the business model in which it is held. 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 using observable inputs such as market prices for implied volatility, foreign exchange and interest rates. Where there are no observable market data, fair values are calculated using other inputs such as data from transactions, external evidence on exit price or other analytical techniques. Financial assets at amortized cost Interest bearing assets, including cash equivalents, held with the objective to collect contractual cash flows, are classified as amortized cost assets. These include securities and deposits not managed on a fair value basis and loans Financial assets at fair value through other comprehensive income (FVOCI) Trade receivables are classified as FVOCI because the business model is primarily to collect, with occasional sales. Sale of trade receivables are made when the liquidity need arises and competitive prices are available for such a sale. 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. Derivatives are classified as FVTPL, unless they are designated as hedging instruments for the purpose of hedge accounting. Derivatives assets and liabilities are offset where there is legally enforceable right to offset non-current Interest-bearing assets including investment in securities and money market funds are classified as FVTPL where they are either held in a portfolio managed on a fair value basis or held for short-term liquidity purposes. Customer finance receivables are classified as FVTPL because they are primarily held for sale. These assets are presented on the balance sheet based on their maturity date (i.e., those with a maturity longer than one year are presented as non-current). non-current Gains or losses arising from changes in the fair values of investment in shares and participations are presented in the income statement within other operating income. Gains and losses on derivatives are presented in the income statement as follows: Gains and losses on derivatives used to hedge foreign exchange risks are presented within net foreign exchange gains and losses. Gains and losses on interest rate derivatives used to hedge financial assets and liabilities are presented in financial income and financial expense, respectively. Gains and losses on revaluation of customer financing receivables are presented in the income statement as selling expenses. Gains and losses arising from changes in the fair values of all other assets in the FVTPL category are presented in the income statement within financial income. 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 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). The Company adopts a simplified approach for trade receivables and contract assets whereby allowances 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 on a separate line in the income statement. When there is no reasonable expectation of collection, the asset is written off. Other amortized costs assets are mainly investment grade assets deemed to be low risk hence credit risk is assumed not to have increased significantly since initial recognition. If the Company identifies evidence of significant change in credit risk on the assets, lifetime ECL is used to calculate allowance on the asset. Default is deemed if the asset is more than 90 days past due, after which lifetime ECL is also used to calculate allowance on the asset. 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. Trade payables Trade payables are recognized as amortized cost liabilities. Some suppliers sell their Ericsson receivables to banks and the Company The Company the Company’s the Company’s Borrowings Borrowings issued by the Parent Company are designated FVTPL where they are managed on a fair value basis. These are long term borrowings held in an Asset and liability management portfolio where the interest rate risk is managed by matching fixed and floating interest rates of interest-bearing balance sheet items. Changes in fair value of this portfolio are recognized in financial expense, except for changes in fair value due to changes in credit risk which are recognized in other comprehensive income. Borrowings not managed on a fair value basis are classified as amortized cost liabilities. These include revolving credit facilities and commercial papers program which are used for short term liquidity purposes and cash collaterals received. Borrowings are presented 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. Cash flow hedge accounting The Company has the following recurring hedge programs: a) Certain customer contracts where a fluctuation in the USD/SEK foreign exchange (FX) rate would significantly impact net sales. These contracts are multi-year contracts denominated in USD with highly probable payments at fixed points in time. b) Highly probable forecasted sales denominated in USD in Ericsson AB ( For both programs, the Company enters into FX forward contracts that match the terms of the foreign exchange exposure as closely as possible and designates 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 designates changes in forward rates as the hedged risk. When applying hedge accounting, the effective portion of changes in the fair value of derivatives that is designated and qualifies 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. In addition to the recurring hedge programs, cash flow hedge is also designated for certain highly probable acquisition expected to be transacted in foreign currencies. FX derivatives are used as hedging instruments, at a hedge ratio of 1:1. The Company designates changes in forward rates as the hedged risks. The accounting is similar to that described for the cash flow hedge above, except that upon recognition of the hedged acquisition, the cumulative amount in the cash flow hedge reserve is released and recognized as a basis adjustment to the goodwill. Employee related For further disclosure, see the notes under section G. Post-employment benefits Pensions and other post-employment benefits are classified as either defined contribution plans or defined benefit plans. These include gratuity plans, medical plans and leave encashment plans which are expected to be provided to employees over a period longer than 12 months. 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 for such bonds such as Sweden the market yields on government bonds are used. The calculations are based upon actuarial assumptions that are updated annually. 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, referred to as ‘asset ceiling’. The pension asset is presented as Other Financial assets, non-current. Interest cost on the defined benefit obligation and interest income on plan assets is calculated as a net interest amount and presented within Financial expenses. Curtailment gains and losses due to restructuring programs are recognized 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 relates to remuneration to employees, including key management personnel and the Board of Directors, and could be settled in either shares or cash. The majority of the granted share-based programs are cash-settled, except for programs for the Executive Team and the long-term variable compensation (LTV) 2023 program. These programs are share-settled. Share-settled plans will be settled in the Parent Company Class B shares provided the market-related and non-market-related Share-settled plans Compensation costs are recognized during the vesting period, based on the fair value of the Ericsson share at the grant date, and considers performance and market-related vesting conditions. All plans have service conditions, while some have performance and market-related vesting conditions. Examples of performance conditions could be revenue and profit targets and market conditions relate to the development of the Parent Company’s share price in relation to a group of reference shares. For further detailed information, see note G3 “Share-based compensation.” 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 the end of the service period. The fair value of the synthetic shares, being the cash equivalents of shares, is therefore reassessed and amended du

Disclosure Of Accounting Judgements And Estimates [Abstract]
A2 Critical accounting estimates and judgments	Critical accounting estimates and judgments 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 with a change in strategy or restructuring. Judgments for accounting policies to be applied as well as estimates may also be impacted due to this. The 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 material 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 particularly when determining the transaction price and its allocation to performance obligations identified under the contract. Transaction price, including variable considerations, for example volume rebate earnings, 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. This includes assessment of price concession based on latest available information on contract negotiations that could have retrospective impact on prices for products and services already ordered or delivered. The Company uses an adjusted market assessment approach to estimate stand-alone selling prices for its products and services for the purposes of allocating transaction price. 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 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 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. Judgment may be applied in determining whether risk and rewards have been transferred to the customer and whether the customer has accepted the products. 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. Impairment allowance on receivables and contract assets Key sources of estimation uncertainty The Company monitors the financial stability of its customers, the environments in which they operate and historical credit losses. This is combined with expectations of future economic conditions to calculate expected credit losses (ECLs). ECLs on trade receivables and contract assets are assessed using a provision matrix based on days past due for groupings of customers that are classified as low, medium and high. The amount of ECLs is sensitive to changes in the payment patterns, circumstances of our customers and the environments in which they operate as well as management’s expectations of future economic conditions. Actual credit losses may be higher or lower than expected, therefore are regularly monitored to ensure the provision matrix is updated if required. Total allowances for expected credit losses as of December 31, 2023 were SEK 2.6 (2.5) billion or 5% (4%) of gross trade receivables and contract assets. For further detailed information see note F1 “Financial risk management”. Customer financing receivables 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. At December 31, 2023, the fair value of customer finance receivables amounted to SEK 6.9 (5.4) billion. For further detailed information see note F1 “Financial risk management”. 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, prices and inventory balances. Inventory write-downs during the period, amounted to SEK 4.0 (3.9) billion or 10% (8%) of gross inventory at year end Judgments made in relation to accounting policies applied In situations where excess inventory balances are identified, estimates of net realizable values for the excess volumes are made. Allowances for obsolescence in inventory considers aging, historical consumption and judgments around market demands. There may also be judgments around internal and external circumstances, e.g. withdrawal of a product or economic and political changes in the global market. Acquired customer relationships, intellectual property rights and other intangible assets, including goodwill 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 asset. After initial recognition, impairment testing is performed when there is an indication of impairment. Additionally, goodwill impairment testing is performed once per year aligned with updated business plans. An indication of impairment may be a material deviation in actual cash flows compared to the business plan as well as new estimates that indicate lower future cash flows. The estimation uncertainty is considered higher for At December 31, 2023, the carrying amount of acquired intangible assets amounted to SEK 75.6 (110.9) billion, including goodwill of SEK 52.9 (84.6) billion. For further discussion on goodwill, see note A1 “Material accounting policies.” Estimates related to acquired intangible assets are based on similar assumptions and risks as 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 impairment indicators. Management judgment is required for the purchase price allocation, for example when determining the fair values of acquired intangible assets. Judgment is also required in defining the cash-generating units for impairment testing purposes. Leases Key sources of estimation uncertainty Estimation uncertainty exists due to possible future changes in business operations, which may impact the actual lease term of a contract. For example, if a restructuring program is initiated which could mean termination of existing lease contracts. The determination of the rates at which the lease liabilities are discounted is another uncertainty and this affects the lease liability and interest expense amounts. At December 31, 2023, lease liabilities amounted to SEK 7.5 (9.3) billion. For more information, see note C3 “Leases.” Judgments made in relation to accounting policies applied At initial recognition and subsequent remeasurement, management judgment is used for the term applied in a lease contract. The outcome of these judgments may turn out not to match the actual outcome of the lease and may have an adverse effect on the right-of-use right-of-use Provisions and contingent liabilities Key sources of estimation uncertainty The key sources of estimation uncertainty relating to provisions are the assessment of the probability of outflow and whether a reliable estimate can be made. Supplier-related provisions require a reliable forecast of sales volumes to estimate the expected usage of the committed inventory purchases. Therefore, estimation uncertainty exists regarding the forecast and expected usage to assess the risk and the provision amount. Estimation uncertainty exists regarding restructuring provisions as the eventual outcome of the program, in terms of costs and actual impacted employees, may differ from the estimates made in the management plan. Estimation uncertainty exists with respect to ongoing internal investigations, proceedings and other matters with government and regulatory authorities. The Company’s internal investigation and its cooperation with authorities in relation to the matters discussed in the 2019 internal Iraq investigation report remain open and ongoing. Estimation uncertainty over the expected settlement relating to litigation and disputes including intellectual property related topics such as patents exists as they may continue over several years and the outcome is unknown. The same estimation uncertainties described above for provisions exist for contingent liabilities. Contingent liabilities mainly relate to estimates for litigation Provisions and contingent liabilities are regularly reassessed based on the latest information available and are adjusted to reflect the Company’s best estimate of the eventual outcome. At December 31, 2023, provisions amounted to SEK 11.7 (11.6) billion. For further detailed information, see note D1 “Provisions.” At December 31, 2023, contingent liabilities disclosed amounted to SEK 3.0 (3.3) billion. For further detailed information, see note D2 “Contingent liabilities” including a description of contingent liabilities which cannot be quantified. Judgments made in relation to accounting policies applied The nature and type of risks for these provisions and contingencies differ and management applies judgment regarding the nature and extent of the obligations in deciding the probability of the outcome. Further judgment is required in determining the value of the present or possible obligation as this is based on the Company’s best estimate as to the expected future expenditure required to settle the obligation. 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 depth 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, 2023, defined benefit obligations for pensions and other post-employment benefits amounted to SEK 85.5 (83.7) billion and fair value of plan assets amounted Accounting for deferred tax Key sources of estimation uncertainty 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 and/ or tax credits in different tax jurisdictions. All deferred tax assets are subject to annual review of probable utilization. The valuation of temporary differences, tax loss carry-forwards and tax credits are based on management’s estimates of future taxable profits in different tax jurisdictions against which the temporary differences, loss carry-forwards and tax credits may be utilized. These estimates are primarily based on business plans for the Company´s estimated outcome of future taxable profits. At December 31, 2023, the value of deferred tax assets amounted to SEK 22.4 (19.4) billion. For further detailed information see note H1 “Taxes .” non-current Accounting for income tax, value added tax, and other taxes Key sources of estimation uncertainty Accounting for income taxes is based upon evaluation of taxable income in all jurisdictions where the profits arise. As prescribed in IFRIC 23, only uncertainty over income tax treatment is considered if and when recognizing and measuring income tax items in the financial statements. Assets relating to value added tax, and other taxes are separately assessed for recoverability in each jurisdiction according to the local regulations. 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. Climate-related factors Judgments made and key sources of estimation uncertainty The Company has considered the effect of climate-related factors on the financial statements, see references in the notes B5 “Inventories“ and C1 “Intangible Assets“ on measurements of non-financial

The amount of inventories recognized as expense and included in Cost of sales was SEK 65,042 (68,838) million. During the period, write-downs of inventory to net realizable values were reversals in Contract work in progress consists of costs incurred to date on customer projects where the performance obligations are yet to be fully delivered. These costs will be recognized as cost of sales when the related revenue is recognized in the income statement. The Company has had to increase its buffer of vital components to mitigate the supply chain issues affecting electronic components globally. Inventory allowance is reviewed periodically to ensure obsolete components are adequately provided for. The Company’s current climate-related strategy’s aim to have a portfolio of energy efficient products may affect recoverability of inventories as customers push for fast substitution and uptake of volume towards the most energy efficient products. The current radio product offering largely reflects the latest and most energy efficient technologies and ongoing improvements are expected in future. These factors have been included in the inventory obsolescence risk assessment at year end. Physical risks of climate changes on manufacturing facilities have also been identified as a potential climate-related risk to the Company’s operations, although these risks are mostly mitigated through having appropriate insurance policies for damage to inventories and fixed assets, as well as potential business interruptions. The Company also has a globally spread production capability as well as geographically diverse sourcing channels to mitigate risks of supply interruptions due to natural disasters, including severe weather events.

Within Enterprise carries Impairment losses In 2023 an impairment charge of goodwill attributed to the acquisition of Vonage by SEK -31.9 billion For more information, see note E2 “Business combinations.” this amount was determined by value in use and was higher than the value determined by Fair value less costs of disposal. In 2022 there was an impairment loss of intangibles of SEK 61 million in a business related to the Internet of Things in segment Enterprise due to a strategic decision to discontinue the business operation, which is reported on the line item Research and development expenses in the income statement. In 2021 there was an impairment loss of SEK 176 million in the restated segment Enterprise and an impairment loss of SEK 137 million in the restated segment Cloud Software and Services. Intangible assets The carrying value of customer relationships, IPR, and other intangible assets is SEK 22.7 (26.3) billion, of which customer relationships, acquired through the Vonage transaction, amounts to SEK 16.1 Capitalized development expenses The Company capitalizes 5G radio product development costs and Enterprise platform costs which are amortized over a period of 3 years. In considering the Company’s climate-related aim to have more energy efficient products, the Company continually assesses the impact of future radio product improvements on the recoverability of such development costs. The conclusion is that the carrying value at year-end Goodwill allocation Goodwill allocation has not changed during 2023 but goodwill of SEK 0.3 billion of Impairment tests Each of segment Networks and segment Cloud Software and Services is a CGU. There are several CGUs within segment Enterprise. The value in use method has been applied for goodwill impairment testing, which means that the recoverable amounts for CGUs are established as the present value of expected future cash flows based on business plans approved by management. The assumptions are also based on the Company’s market share ambition and 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. Estimation of future cash flows includes assumptions mainly for the following key financial parameters: – Sales growth – Development of EBIT (based on EBIT 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 – By 2028, about 37 years after the introduction of digital mobile technology, it is predicted that there will be 9.1 billion mobile subscriptions (excl. Cellular IoT) compared to 8.5 billion in 2023. Out of all mobile subscriptions, 8.2 billion will be associated with a smartphone. – The number of 5G subscriptions is forecasted to reach 4.7 billion (excluding Cellular IoT) by the end of 2028 compared to 1.6 billion in 2023. – By 2028, about 46 billion connected devices are forecasted compared to 26 billion in 2023, of the 46 billion around 30 billion will be related to Internet of Things, IoT. Connected IoT devices includes connected cars, machines, meters, sensors, point-of-sale – Cellular IoT is predicted to grow from 3.5 billion devices in end of 2024 to 5.5 billion devices in end of 2028. – Mobile data traffic volume is estimated to increase by more than two times in the period 2024–2028. The mobile traffic is driven by smartphone users and video traffic, with mobile video traffic forecasted to grow by almost 25% annually through 2028 to account for more than 70% of all mobile data traffic. Fixed Wireless Access is another contributor to mobile traffic, growing with more than 30% annually in the period to account for more than 25% of all mobile data traffic in 2028. Sales growth in the Enterprise segment is driven by the adoption of 5G and the convergence of 5G and Cloud communications in the enterprise market. The Enterprise Wireless WAN addressable market is expected to grow with a CAGR of 24% 2022–2027. The global CPaaS approximately 24% 2023–2026, with the growth mainly driven by the introduction of high-value API’s . The CGUs Vonage and Cradlepoint have assumed a forecasted compounded annual growth rate above 15% (20%) over the next five years followed by a gradual decline in growth rates. The assumptions reflect the expected high growth market conditions in which both CGUs are present. Market maturity and market growth at long term sustainable levels (nominal rates described above) are not expected to be reached until after the 5-year The forecasted cash flows to calculate recoverable amounts are based on five-year explicit business plans. For the CGUs Vonage and Cradlepoint an additional two years have been added to reflect the progression towards the steady state cash flow projections. There are no reasonably possible changes that would lead to the carrying value not being recoverable for any CGU, except for Vonage. The recoverable amount of CGU Vonage exceeds the carrying amount by SEK 1.1 billion. This CGU was written down to its recoverable amount in Q3 2023. The current head room comes mainly from the amortization of intangible assets since the write-down. The recoverable amount for CGU Vonage would equal the carrying value, if the long-term EBIT margin would be decreased by %, or if sales CAGR during the forecast period or terminal growth rate decreased by .

Risk assessment in the ongoing business is performed monthly to identify the need for new additions and reversals. 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 provision balance as a reversal. In other cases, the outcome can be negative, and if so, a charge is recorded in the income statement. For 2023, the total provision value is SEK 11.7 (11.6) billion, of which SEK 4.9 (4.0) billion is classified as non-current. cost-reduction approximately non-criminal, Restructuring provisions Restructuring provisions relate to structural efficiency programs that are planned and controlled by management and have a material impact on either the scope of the business undertaken or the manner in which the business is conducted. Restructuring provisions in 2023 relate to the cost-reduction programs, which may impact Customer-related provisions Customer-related provisions mainly consist of provisions for losses on customer contracts. To measure the customer-related provisions, management estimates the unavoidable costs to fulfill the obligations under the customer contract. If the exit penalty is lower than the estimated costs to fulfill the contract, then the provision value is limited to the exit penalty value. The unavoidable costs to fulfill the contract sometimes differ from management’s estimates. Provisions raised for loss-making customer contracts are therefore regularly reviewed and adjusted based on the latest information available considering the realization of the costs estimated. The expected timing and amount of outflows are dependent on whether the customer contract execution is in line with management’s assessment. The majority of the customer-related provisions will be utilized over 5 years. Supplier-related provisions Supplier-related provisions are for supplier claims/guarantees based on the contractual obligations mostly relating to inventory. The provision is calculated by comparing the committed inventory purchases with the expected usage based on a forecast of sales volumes, and any excess is provided for based on an assessment of the risk of obsolescence. If the committed inventory is not required to be purchased, but a fee is chargeable by the vendor due to the failure to meet the committed volumes, then the provision is based on the expected fee to be incurred. Estimation uncertainty exists regarding the expected usage and sales volumes forecast and, if applicable, the assessment of the risk of obsolescence, as these are based on management’s expectations. When the committed inventory is purchased, the provision is reclassified from provisions to inventory allowances. The expected timing and amount of outflows are dependent on the actual outcome of the supplier claims and guarantees. The majority of the supplier-related provisions will be utilized over 2 years. 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. Uncertainty exists regarding the timing and amount as management utilizes the historical trends to estimate the warranty provisions as well as the cost to repair or replace, which may differ from the actual outcomes. New product warranty provisions require further estimation since historical information is not available. These provisions do not include costs for service in additions within customer contracts that are accounted for as separate performance obligations. The expected timing and amount of outflows are dependent on the actual product faults which may occur. The majority of the warranty provisions are expected to be utilized within 1 year. Share-based payments provisions Share-based payments provisions relate to cash-settled share-based programs and are based on the present period’s best estimate of the eventual pay-outs, Other provisions Other provisions mostly relate to litigation and patent infringement disputes. Management regularly assesses the likelihood of any adverse outcomes relating to ongoing litigations and disputes, and if deemed probable then a provision is raised based on the best estimate of the expenditure required to settle with the counterpart. There is uncertainty in the final outcome and settlement, therefore management reviews the estimation regularly. Outflows relating to litigations are inherently uncertain regarding timing and amount, and therefore the majority of the provisions are classified as current, but outflows may happen over a number of years depending on when settlement is reached.

Disclosure of contingent liabilities [abstract]
D2 Contingent liabilities	Contingent liabilities Contingent liabilities 2023 2022 Contingent liabilities 3,037 3,322 Total 3,037 3,322 Contingent liabilities mainly relate to, in order of materiality, tax litigations in subsidiaries, other , including related to intellectual property matters The Company actively manages its IPR portfolio and its need for third party licenses and is involved from time to time, in the ordinary course of business, in litigation related thereto, as plaintiff, defendant and other capacities. The Company also monitors the performance of obligations due to it by third party vendors and other suppliers and takes appropriate action where necessary to secure such performance. Outflows relating to litigation, both tax and legal, due to their nature are inherently uncertain regarding timing and amount. All ongoing litigations are, therefore, regularly evaluated, their potential economic outflows and probability estimated, and necessary provisions made, or contingent liabilities disclosed. 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. As part of its defense to a now settled patent infringement lawsuit filed by Ericsson in 2013 in the Delhi High Court against Indian handset company Micromax, Micromax filed a complaint against Ericsson with the Competition Commission of India (CCI). The CCI decided to refer the case to the Director General’s Office for an in-depth On July 13, 2023, the Division Bench of the Delhi High Court found that in this instance the CCI has no power to conduct the pending investigations against Ericsson. The CCI has appealed this order to the Supreme Court of India. In April 2019, Ericsson was informed by China’s State Administration for Market Regulation (SAMR) Anti-monopoly bureau that SAMR has initiated an investigation into Ericsson’s patent licensing practices in China. Ericsson is cooperating with the investigation, which is still in a fact-finding phase. The next steps include continued fact finding and meetings with SAMR in order to facilitate the authority’s assessments and conclusions. The above matters relating to Micromax and SAMR are possible obligations which cannot be quantified and are, therefore, not included in the contingent liability amount disclosed in the table.

F1 Financial risk management	Financial risk management 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 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 invest in 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: – Free cash flow before M&A of 9–12% of net sales – Positive net cash position – Investment grade rating by Moody’s (Baa3), S&P Global (BBB –) –). Capital objectives-related information 2023 2022 Free cash flow before M&A as % of net sales 1) –0.4% 8.2% Positive net cash (SEK billion) 1) 7.8 23.3 Credit rating and outlook Fitch Ratings BBB–, stable BBB–, stable S&P Global BBB–, BBB–, Moody’s Ba1, stable Ba1, stable 1) For more information about the measures, see Alternative performance measures and Financial terminology. The ratings and outlooks have remained unchanged throughout 2023. The Company has a Treasury and Customer Finance organization with the principal role to ensure that appropriate financing is in place through loans and committed credit facilities, actively manage the Company’s liquidity as well as financial assets and liabilities, and manage and control financial risk exposures in a manner consistent with underlying business risks and financial policies. The Customer Finance function may support with suitable third-party financing solutions for customers to facilitate their purchases from Ericsson. In some cases, and to the extent that customer loans are not provided directly by banks, the Parent Company may provide vendor finance credits to customers directly. 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 risk – 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 “Material accounting policies.” Foreign exchange risk The Company is a global company with sales mainly outside Sweden. Sales and costs incurred 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 will impact 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 EBIT 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 changes in foreign exchange rates. The table below presents the external net sales and cost exposures for the largest currencies which impact profitability. The internal exposures will not impact group profitability if all related transactions occur and are recognized in the profit and loss in the same month. Any effect on profit and loss from internal transactions is a function of timing and FX volatility, therefore impossible to predict.

Based on the outstanding cash flow hedge volume at year end, the hedged sales volume that will occur in 2024 is USD 2,467 million. 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 the following transaction exposures. a) Transaction risk impacting net sales and net 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 the following recurring hedge programs: i) The Company has identified certain customer contracts where a fluctuation in the USD/SEK foreign exchange rate would significantly impact net sales. 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 the next three years receipts on a rolling basis, up to the end of the contract period. This mandate instructs the treasury function to hedge a percentage of this exposure according to a defined scale, locking in a higher percentage of exposure as the USD strengthens against SEK, up to 100%. ii) The Board of Directors has provided a mandate to the Company to hedge highly probable forecasted sales and purchases denominated in USD in EAB for the next 7 to 18 months, on a monthly rolling basis. This mandate instructs the treasury function to hedge a percentage of this exposure according to a defined scale, locking in a higher percentage of exposure as the USD strengthens against SEK, up to 100%. For both programs, 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. 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. The sensitivity of the FX impact is dependent on changes in foreign exchange rates, forecasts and seasonality. USD is the only currency being hedged. Since the start of the 7 to 18 month cash flow hedge program in March 2022, the USD sales volume funded by internal loan has steadily reduced, whereas the USD purchases volume reduced to a lesser extent. This resulted in a net deposit balance with its parent company throughout the second half of 2023. The outstanding net deposit at year-end is USD 199 million (loan of USD 149 million), with an average net loan balance of USD 52 million (USD 529 million) over the year. Net realized FX gain recognized is SEK 4 million and unrealized loss is SEK 211 million, giving a total net loss of SEK 207 million. d) Transaction risk impacting business combination The Company is exposed to FX execution risk on consideration payable for acquisition in foreign currency from the period of communication of the proposed transaction to final completion date. Such transaction, if deemed material and highly probable, will be hedged to protect the cash consideration for acquisition accounting. Cash flow 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 item and the hedging instruments. 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 income 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), with the limitation that historical data does not necessarily reflect future events. 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 2023 was SEK 15.9 (21.0) million. No VaR limits were exceeded during 2023. 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 2023 was SEK 1.5 (1.5) million per basis point shift.

Cash collaterals paid or received under Credit Support Annex (CSA) to ISDA for cross-currency derivatives are recognized as Interest-bearing securities, current or Borrowings, current, respectively. The Company holds the following currency derivatives designated as hedging instruments: Foreign exchange forward contracts 2023 < 3 3 – 12 > 1 year Total Notional Amount (USD millions) 1,091 1,376 1,888 4,355 Average forward rate (SEK/USD) 9.81 10.46 10.03 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. For hedge on customer contracts, 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. For hedge on business combination, the cumulative amount in hedge reserve is transferred as a basis adjustment to goodwill upon recognition of the business combination. See note E1 “Equity” for movement in the cash flow hedge reserve. No hedge ineffectiveness was recognized in the income statement in 2023. 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 “Material 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 is generated in the source system. These are based on the credit limit and risk profile set on the customer. Credit blocks appear if credit limit is reached or 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. 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 of 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. The Company has assessed the recent global economic conditions on the expected credit losses model for trade receivables and updated the provision matrix as appropriate. Trade receivables and contract assets, net of allowance, amounted to SEK 50,214 (58,256) million as of December 31, 2023. Provisions for expected credit losses on trade receivables and contract assets amounted to SEK 2,585 (2,492) million as of December 31, 2023. Total past due more than 360 days has increased, resulting in a higher allowance as a percentage of gross exposure at year end. The Company’s write-offs have historically been low. During the year SEK 35 (70) million were written off due to the Company having no reasonable expectation of collection.

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 analyzing 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 the relevant base rate. 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, 2023, the total amount payable to the Company under customer finance credits was SEK 9,681 (7,758) million. The carrying value of these assets was SEK 6,917 (5,370) million as of December 31, 2023. Customer finance is arranged for infrastructure projects in different geographic markets. As of December 31, 2023, there were a total of 65 (73) customer finance arrangements originated by or guaranteed by the Company. As of December 31, 2023, the five largest facilities, calculated based on gross exposure, represented 86 74 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 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. The table below summarizes the Company’s outstanding customer finance as of December 31, 2023 and 2022.

Fair value assessment of customer finance credits Customer finance risk exposures are held at fair value and are classified as Level 3 in 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 (excluding effect of foreign exchange translation) amounted to a net loss in the consolidated income statement of SEK 209 million in 2023 (loss of 15 million), of which net loss of SEK 209 million related Customer finance fair value reconciliation   2023   2022 Opening balance 5,370 3,287 Additions 49,583 37,295 Disposals/repayments –47,409 –35,412 Revaluation/amortization of interest –467 –151 Translation difference –160 351 Closing balance 6,917 5,370  Of which non-current 1,347 415 Due to the 5G buildout, the demand for customer financing arrangements has continued to increase significantly. Most of such financing arrangements have been transferred to banks. 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 derivatives 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, 2023, 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 0.4 (0.8) billion. 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, analyzed by contractual maturity, see note D4 “Contractual obligations.” The short-term commitment on debt in the next 12 months are sufficiently covered by cash and other interest-bearing assets at year end. Ongoing collection from customers are expected to satisfy operational requirements including trade payables and other purchase obligations. Commitments for new customer finance is not expected to have negative short-term effect on collection as majority are sold within a short period. Where required, the Company expects short-term borrowing facilities to be drawn down or rolled over to meet liquidity needs.

The Company mitigates the risk by having diversified funding sources through a mix of bonds, bilateral loans and private placements, with a spread of debt maturing over time. The funding strategy is flexible to enable pre-financing before loan maturities and funding in various currencies. The average maturity of long-term borrowings is 3.7 years (3.8 years) at December 31, 2023. In addition to the long-term funding programs, the Company has a commercial paper program and a committed liquidity revolving credit facility for short-term borrowings.

In November 2023, the Company issued a 4.5-year EUR 500 million green bond under the Euro Medium Term Note program and Green Financing Framework. During the year, the Company established a new committed liquidity revolving credit facility of USD 1.0 billion, of which USD 0.4 billion was utilized as at year end, and increased the borrowings under the commercial paper program by SEK 2.0 billion. Furthermore, the Company signed two 7-year loan agreements, one with European Investment Bank for USD 273 million and one with Nordic Investment Bank for USD 107 million.

The facility does not have interest rates linked to credit rating or financial covenants but is linked to two of Ericsson’s sustainability KPIs. 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 as they are based on quoted prices in active markets for identical assets. For some of the Company’s financial assets and liabilities, especially derivatives, quoted prices are not readily available and fair values are calculated using market inputs such as interest rate quotes and currency rates. For financial liabilities designated at fair value to profit and loss, the carrying amount reflects the effect in own credit spreads either in quoted prices or quoted Credit Default Swap (CDS) for Investment Grade companies. Valuation hierarchy – Quoted market prices – level 1 Assets and liabilities are classified as level 1 if their value is observable in an active market. Such instruments are valued by reference to unadjusted quoted prices for identical assets or liabilities in active markets where the quoted price is readily available, and the price represents actual and regularly occurring market transactions. – Valuation technique using observable inputs – level 2 Assets and liabilities classified as level 2 have been valued using models whose inputs are observable either directly or indirectly. Valuations based on observable inputs include cash equivalents (e.g. discounted papers, term deposits) and interest rate derivatives which are valued using interest rate yield curves. Other market observable inputs include credit spreads and FX forward rates. Inputs for base interest rates are quoted fixing rates, interest rates swaps and IBOR rates. FX derivatives are valued by using observable forward rates, discounted using base interest rate curve. Valuation of foreign exchange options are made using the Black-Scholes formula. The value of credit risks in derivative contracts are monitored regularly. Derivative credit and debit valuations adjustments are calculated based on outstanding market values and default probabilities from the CDS market, and if effect on valuation is material, are included in the fair value of the derivatives. – Valuation technique using significant unobservable inputs – level 3 Assets and liabilities are classified as level 3 if their valuation incorporates significant inputs that are not based on observable market data (unobservable inputs). Apart from trade receivables and customer finance receivables, this valuation technique mainly applies to investment in shares and other participations whereby valuation input is considered observable if it can be directly observed from transactions in an active market, or if there is compelling external evidence demonstrating an executable exit price. Using a market approach to valuation, unobservable inputs are generally determined via reference to observable inputs, historical observations or other analytical techniques.

Financial instruments carried at amortized cost 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.

To secure long-term funding, the Company uses notes and bond programs together with bilateral research and development loans, as well as private placements. All outstanding notes and bond loans are issued by the Parent Company under its Euro Medium Term Note (EMTN) 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.” In addition to the long-term funding programs, the Company has a commercial paper program and a committed liquidity revolving credit facility to efficiently manage liquidity needs, further described in note F1 “Refinancing risk.” Total weighted average interest rate cost for parent company funding during the year was 5.15% (2.45%). The global economy continues to face multiple challenges due to geopolitical uncertainty and the threat of economic downturn affecting all major economies. Central banks across the world have raised interest rates in response to inflation. The higher short-term interest rates increased interest payments on long-term borrowings as fixed coupons payments are normally swapped to floating rates. As all long-term borrowings are also denominated in either USD or Euro, interest payments and cost of borrowings in SEK have increased compared to prior years.

G1 Post-employment benefits

Disclosure of information about defined benefit plans [abstract]
G1 Post-employment benefits	Post-employment benefits Ericsson sponsors a number of post-employment benefit plans throughout the Company, which are in line with market practice in each country. The Company has updated the assumptions used to value the defined benefit pension liabilities based on the latest market conditions. Financial assumption changes resulted in net actuarial gains on defined benefit obligations of SEK 0.9 billion although this was largely offset by changes in demographic assumptions and experience losses. 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 59% (57%) by the assets of Ericsson Pensionsstiftelse (a Swedish Pension Foundation). These liabilities, if valued using different methodology and assumptions established by the Swedish PRI Pensionsgaranti, 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. 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 collective funding ratio ranges from 125% to 175% and reflects the market value of Alecta’s plan assets as a percentage of its commitments to policy holders (both guaranteed and non-guaranteed), measured in accordance with Alecta’s actuarial assumptions, which are different from those in IAS 19. Alecta’s collective funding ratio was 158% (172%) as of December 31, 2023. The Company’s share of Alecta’s saving premiums is 0.4% and the total share of active members in Alecta is 2.1%. The expected contribution to the plan is SEK 95 million for 2024. 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 7.4 billion to PRI Pensionsgaranti at year end. PRI continuously measures the Company credit risk levels according to the credit insurance terms and conditions. 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 2023. 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. 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’s aim Other plans The Company also sponsors plans in other countries. The main plans are in Brazil, India 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. The Provident Fund Plan in India is self-managed through a registered Exempted Trust and according to local legislation, investment returns shall be guaranteed at minimum rates of return specified by the government. The Company has an obligation to fund any shortfall on the yield of the trust’s investments over the administered interest rates on an annual basis. These administered rates are determined annually predominantly considering the social and economic factors in the past.

See also note A1 “Material 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, 2023, the discount rate applied in Sweden was 2.1% (2.0%). If the discount rate had been based on Swedish covered mortgage bonds, the discount rate as of December 31, 2023 would have been 3.5% (3.9%). If the discount rate based on Swedish covered mortgage bonds had been applied for the pension liability calculation, the DBO at December 31, 2023 would have been approximately SEK 12.1 (16.5) billion lower. US and UK The defined benefit obligation has been calculated using a discount rate based on yields of high-quality corporate bonds, where “high-quality” has been defined as a rating of AA and above.

The number of synthetic shares would then have been 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 2028.

Synthetic shares were allocated to members of the Board for the first time in 2008 and have been allocated annually since then on equal terms and conditions. Payment based on synthetic shares allocated in 2018 occurred in 2023. The amounts paid in 2023 under the synthetic share programs were determined based on the volume-weighted average price for Ericsson’s Class B shares on Nasdaq Stockholm during the five trading days immediately following the publication of the year-end financial statements for 2022: SEK 59.91 and totaled SEK 6,350,763, excluding social security charges. The payments made do not constitute a cost for the Company in 2023. The Company’s costs for the synthetic shares have been disclosed each year and the net change in value of the synthetic shares for which payment was made in 2023, is disclosed in the table above “Remuneration to members of the Board of Directors”. The value of all outstanding synthetic shares fluctuates in line with the market value of Ericsson’s Class B share and may differ from year to year compared to the original value on their respective grant dates. The change in value of the outstanding synthetic shares is established each year and affects the total recognized costs that year. As of December 31, 2023, the total outstanding number of synthetic shares under the programs is 241,184 and the total accounted debt is SEK 16,690,551.

G3 Share-based compensation	Share-based compensation Accounting treatment of Long-Term Variable Compensation Programs In note A1” Material accounting policies”, the overall accounting policies for share-based payments within the Company are disclosed. In summary: – Share-settled programs, the total compensation expense is calculated based on the fair value (FV) at grant date and recognized over the service period of three years. – 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 or 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 (service 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. To reinforce a strong alignment between our shareholders and our Executives the LTV 2023 for Executives will grant, vest and be delivered in Ericsson Class B-shares. Until LTV 2022 Executive Performance Plan (EPP), the granting and vesting has been in synthetic shares with the outcome delivered as a cash settlement. With this action the new Long-Term Variable Compensation Program (LTV) for the Executive Team (ET) and the Executive Performance Plan (EPP) for senior managers have merged into one plan. All programs are share-based payment programs as defined by IFRS 2 “Share-based Payment,” either share- or cash-settled. The significant share-based payment programs are described below. Share-Settled Programs Long-Term Variable Compensation Program for the Executive Team The Long-Term Variable Compensation Program for the ET and Executives as approved by the shareholders, is designed to provide long-term incentives for members of the ET and Executives, to incentivize the Company’s performance creating long-term value. 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 (vesting period). Allotment of shares pursuant to Performance Share Awards are subject to the achievement of 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 (performance period). The performance criteria for the currently running LTV and EPP are summarized in the below table along with the satisfaction LTV and EPP performance criteria Program Year Target Criteria Weight Performance Period Vesting Opportunity (linear pro-rata) Achievement Achieved Vesting Level 2023 2023 Group operating income (EBITA) Range (SEK billion): 26.4 - 40.4 45% Jan 1, 2023–Dec 31, 2023 0%–200% SEK 21.4 billion 2) 0% 2023 Absolute TSR Range: 6%-14% 25% Jan 1, 2023–Dec 31, 2025 0%–200% 2023 Relative TSR Ranking of Ericsson: 6–2 20% Jan 1, 2023–Dec 31, 2025 0%–200% 1) 2023 Group Environmental, Social and Governance (“ESG”) CO2e emissions (ktonnes): 142–121 1.66% Jan 1, 2023–Dec 31, 2023 0%–200% 121.9 CO 2 193.72% CO2e emissions (ktonnes): 132–113 1.66% Jan 1, 2024–Dec 31, 2024 0%–200% CO2e emissions (ktonnes): 122–104 1.68% Jan 1, 2025–Dec 31, 2025 0%–200% Increasing the representation of women leaders in the Ericsson Group: Range 23%–25% 5% Jan 1, 2023–Dec 31, 2025 0%–200% 2023 Total 100 % 0 %– 200 % 2022 2022 Group operating income (EBIT) Range (SEK billion): 24.1–34.1 45% Jan 1, 2022–Dec 31, 2022 0%–200% SEK 32.2 billion 2) 162.76% 2022 Absolute TSR Range: 6%-14% 25% Jan 1, 2022–Dec 31, 2024 0%–200% 2022 Relative TSR Ranking of Ericsson: 6–2 20% Jan 1, 2022–Dec 31, 2024 0%–200% 1) 2022 Group Environmental, Social and Governance (“ESG”) CO2e emissions (ktonnes): 265–200 5% Jan 1, 2022–Dec 31, 2024 0%–200% Increasing the representation of women leaders in the Ericsson Group: Range 22%–24% 5% Jan 1, 2022–Dec 31, 2024 0%–200% 2022 Total 100% 0%–200% 2021 2021 Group operating income (EBIT) Range (SEK billion): 15.0–24.0 50% Jan 1, 2021–Dec 31, 2021 0%–200% SEK 27.4 billion 2) 200% 2021 Absolute TSR Range: 6%–14% 30% Jan 1, 2021–Dec 31, 2023 0%–200% -16.17% 0.00% 2021 Relative TSR Ranking of Ericsson: 6–2 20% Jan 1, 2021–Dec 31, 2023 0%–200% 1) 12 out of 11 0.00% 2021 Total 100% 0%–200% 100.00% 2020 2020 Group operating income (EBIT) Range (SEK billion): 19.1–27.9 50% Jan 1, 2020–Dec 31, 2020 0%–200% SEK 29.1 billion 3) 200% 2020 Absolute TSR Range: 6%–14% 30% Jan 1, 2020–Dec 31, 2022 0%–200% –6.65% 0.00% 2020 Relative TSR Ranking of Ericsson: 6–2 20% Jan 1, 2020–Dec 31, 2022 0%–200% 1) 12 out of 11 0.00% 2020 Total 100% 0%–200% 100.00% 1) The portion of the Performance Share Awards granted to a participant based on the relative TSR performance condition is subject to fulfilment of the related performance criteria over the performance period compared to Peer Groups consisting of 11 companies for the program year 2023, 2022, 2021 and 2020. 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 restructuring charges and items not included in target performance criterion. 3) Excludes restructuring charges. 4) Excludes fines and similar related to the United States Department of Justice (DOJ) / U.S. Securities and Exchange Commission (SEC) resolution, including payments required pursuant to the DOJ Plea Agreement announced by the Company on March 2, 2023. and achieved vesting levels for the ones where 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 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. 2023 Long-Term Variable Compensation Program for the Executive Team (LTV 2023) LTV 2023 was approved at the Annual General Meeting (AGM) of shareholders held in 2023 and includes all members of the ET and Executives, a total of 176 members in 2023, including the President and CEO. The participants were granted Performance Share Awards on May 18, 2023. The value of the underlying shares in respect of the Performance Share Awards made to the President and CEO was 190% 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 Awards 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 fourth quarter of 2022. Having evaluated the ongoing long-term variable compensation programs and considering investor input obtained, the Remuneration Committee and the Board of Directors proposed to the Annual General Meeting of shareholders 2023 a long-term variable compensation program 2023 similar to the long-term variable compensation program 2022 adjusting the Group Environmental, Social and Governance performance criterion (“ESG”) on reducing carbon dioxide equivalent (“CO 2 The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2023 to December 31, 2025 (the performance period).

Having evaluated the ongoing long-term variable compensation programs and considering investor input obtained, the Remuneration Committee and the Board of Directors proposed to the Annual General Meeting of shareholders 2022 a long-term variable compensation program 2022 for the Executive Team similar to the long-term variable compensation program 2021 adding a Group Environmental, Social and Governance performance criterion (“ESG”). The purpose is to further strengthen Ericsson’s commitment to long-term sustainability and responsible business. Hence again a one-year Group operating income (EBIT) target measured over the period January 1, 2022 to December 31, 2022 was included as a performance condition for LTV 2022 in addition to the standard three-year total shareholder return (TSR) performance conditions, which were also used for LTV 2021, LTV 2020 and LTV 2019 however with different weights. The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2022 to December 31, 2024 (the performance period).

Planned vesting date will be during Q1 2024. Cash-Settled Plans Executive Performance Plans (EPP) No new EPP plan was issued in 2023 as the eligible executives were offered the LTV 2023 share granted and vested Plan. The running Executive Performance Plans (EPP) continue to run over the performance period until vesting as is. The Executive Performance Plan (EPP) is a cash-settled plan which uses the same performance criteria as the ones under the respective year’s long-term variable compensation program for the ET. 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. There are two award levels, high and regular, which represent the potential award levels as a percentage of the participant’s annual gross salary, which are determined separately by the Board of Directors for each year’s plan before the plan is launched. 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 vesting date, and this final amount is paid to the participant in cash gross before tax. Executive Performance Plan 2022 (EPP 2022) 165 senior managers were selected to participate in EPP 2022. The regular award level is set at 15% and the high award level is set at 25% for all countries except for the USA/Canada. The regular and high award levels are set at 35% and 45% respectively in the USA/Canada. Executive Performance Plan 2021 (EPP 2021) 159 senior managers were selected to participate in EPP 2021. The regular award level is set at 15% and the high award level is set at 25% for all countries except for the USA. The regular and high award levels are set at 25% and 35% respectively in the USA. Executive Performance Plan 2020 (EPP 2020) 155 senior managers were selected to participate in EPP 2020. The regular award level is set at 15% and the high award level is set at 25% for all countries except for the USA. The regular and high award levels are set at 25% and 35% respectively in the USA. Executive Performance Plan 2019 (EPP 2019) 161 senior managers were selected to participate in EPP 2019. The regular award level is set at 15% and the high award level is set at 22.5%. The awards under EPP 2019 were paid in 2022 at the end of the vesting period and EPP 2019 was officially closed. 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. As of the KC 2019 plan 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. Accounting wise, 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. The consequence of the staggered payments is a front-end loaded cost for these plans. The accounting model is referred to as staged vesting. 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 vesting date, and this final amount is paid to the participant in cash gross before tax.   Key Contributor Plans 2023 (KC Plan 2023) 10,154 employees were selected to participate in KC Plan 2023. There are at multiple levels between 10%-50% of the participants’ annual gross salary.

Key Contributor Plan 2022 (KC Plan 2022) 7,704 employees were selected to participate in KC Plan 2022. There are at multiple levels between 10%-40% 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 as explained under Key Contributor Plans (KC Plans). (KC Conversion Plan 2022) The KC Conversion Plan is a cash-settled retention plan with 95 participants. The plan has a closed participation group and there will not be any new participants. There is a two-year service period, no performance criteria, (February 2022—February 2024) for receiving the award in full.

Summary Of Material Accounting Policies [Abstract]
Basis of presentation	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 The consolidated financial statements for the year ended December 31, 2023, have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board ( ), The financial statements were approved by the Board of Directors on March 5, 2024. The financial statements are subject to approval by the Annual General Meeting of shareholders. Disclosure about new standards and amendments applied as from January 1, 2023, and the preparations for the adoption of new standards and interpretations not adopted in 2023 are disclosed at the end of this note, see heading Other. Basis of presentation The financial statements are presented in millions of Swedish Krona (SEK). They are prepared on a going concern and historical cost basis, except for certain financial assets and liabilities that are stated at fair value: financial instruments classified as fair value through profit or 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 one comparison year.
Basis of consolidation and composition of the Group	Basis of consolidation and composition of the Group Subsidiaries are all companies for which Telefonaktiebolaget LM Ericsson, directly or indirectly, is the parent. To be classified as a parent, Telefonaktie-bolaget 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. The Company is comprised of the 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 transaction. For practical reason, the Company uses the closing rate of the previous month end as approximation of the prevailing rate at the date of transaction, although spot rate is used for material one-off transaction where appropriate. Foreign currency exchange effect is presented as a net item within Financial income and expenses, reported separately from other financial income and expenses items as this reflects the way the Company manages its foreign exchange risks on a net basis.
Translations of Group companies	Translations of 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. This includes goodwill arising on the acquisition of a foreign entity. Period income and expenses for each income statement are translated at period average exchange rates. For practical reason, the Company uses the closing rate of the previous month end as approximation of the period average exchange rates. All resulting net exchange differences are recognized as a separate component of Other comprehensive income (OCI), i.e. changes in translation reserves. The Company is continuously monitoring the economies with high inflation, the risk of hyperinflation and their
Revenue recognition	Revenue recognition The following paragraphs describe 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.
Standard products and services	Standard products and services Products and services are classified as standard solutions as 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. For hardware sales, transfer of control and revenue recognition, is usually deemed to occur when the equipment arrives at the customer site. Standard product software is sold as an on-premises customer. Control is transferred when software licenses are provided to the customer at a point in time and already activated, or as a released software version, ready to be activated by the customer at a later stage. Revenue is recognized when control of the software is transferred and unconditional right to payment exists. Software licenses are also sold on a when-and-if Revenue for recurring services such as customer support and managed services is recognized as the services are delivered, pro-rata
Enterprise solutions	Enterprise solutions Enterprise solutions comprise mainly of software platform solutions, delivered as-a-service pro-rata Cloud services allow the customer to use hosted software over the contract period without taking possession of the software. Cloud services are highly integrated with the software and the individual components are not considered distinct, hence all revenue is recognized in the period these services are provided. Contract duration ranges from one month to 5 years. Revenue for fixed fee arrangement is recognized on a pro-rata Services sold through wholesalers or distributors are assessed for principal or agent relationship. Wholesalers are treated as agents for services that are activated upon delivery of equipment to the end users since the Company still has the primary responsibility to the customers for providing the services, hence revenue (in the gross amount) is recognized rateably from activation until the end of the contract.
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’s 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.
Customer contract related balances	Customer contract related balances Trade receivables include amounts that are 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. Prices on standard products and services 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. Standard recurring services contracts are billed over time, often on a quarterly basis. 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. For Enterprise solution fixed fee contracts, billing is typically in advance, resulting in contract liability. For usage-based contracts, billing is in arrears, resulting in a receivable. Typical credit term is 30 to 45 days. IPR contracts are upfront 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. 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. Where 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 over the duration of the financing period.
Deferred sales commissions	Deferred sales commissions The Company has various incremental commission costs for internal sales personnel and channel partners that relate to the acquisition of customer contracts in the Enterprise segment. These costs are capitalized as deferred contract acquisition costs (within Other non-current
Segment reporting	Segment reporting The segment presentation, as per each segment, is based on the Company’s accounting policies as disclosed in this note. 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 Company’s segment disclosure about geographical areas is based on the country in which transfer of control of products and services occur. For further information, see note B1 “Segment information.”
Inventories	Inventories Inventories are measured at the lower of cost or net realizable value and using cost formula first-in, first-out 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. An inventory obsolescence provision is recognized as cost of sales in the income statement when identified. 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.
Goodwill	Goodwill As from the acquisition date, goodwill acquired in a business combination is allocated to each cash-generating unit (CGU) expected to benefit from the future 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 the value in use, the estimated future cash flows after tax are discounted to their present value using an after-tax after-tax calculating the discount rate include a tax component. The effect of after-tax before-tax before-tax Additional disclosure is required in relation to goodwill impairment testing: see note A2 “Critical accounting estimates and judgments” and note C1 “Intangible assets.”
Intangible assets other than goodwill	Intangible assets other than goodwill Intangible assets other than goodwill comprise Amortization is charged to the income statement, on a straight-line basis, over the estimated useful life of each intangible asset. Estimated useful lives for customer relationships acquired through the Vonage acquisition are 6 to 9 years. For other acquired intangible assets, such as patents, other customer relationships, trademarks, and software estimated useful lives do not exceed 10 years, and capitalized development expenses usually have a useful life of 3 years. Impairment tests are performed when there is an indication of impairment. Tests are performed in the same way as for goodwill but on an asset level, see above. However, intangible assets not yet available for use are tested annually for impairment. 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 and other technical assets, other equipment, tools and installations, and construction in progress. They are stated at cost less accumulated depreciation and any impairment losses. Depreciation is charged to the income statement 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, generally, 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. Gains and losses on disposals are reported within Other operating income and expenses in the income statement.
Leases	Leases The main types of assets leased by the Company are, in order of materiality, real estate, vehicles and IT-equipment. Leases when the Company is the lessee The Company recognizes right-of-use non-lease At commencement date the lease liabilities are measured at the present value of the lease payments not paid at the commencement date, discounted using the Company’s incremental borrowing rate. The Group estimates its incremental borrowing rate to measure lease liabilities at the present value of lease payments as the interest rate implicit in the lease is not readily determinable. The incremental borrowing rate is calculated considering interest swap rates, the creditworthiness of the entity that signs the lease and an adjustment for the asset being collateralized. Lease payments included in the liability are fixed payments, variable payments depending on an index or rate and penalties for termination of contracts. The right-of-use on a basis expenses The Company applies the recognition exemption for short-term leases and leases for which the underlying asset is of low value and recognizes the lease payments for those leases as an expense on a straight-line basis over the lease term. When the Company acts as a lessor ,
Provisions and Contingent Liabilities	Provisions and Contingent Liabilities 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, the estimated cash flows are discounted to present value. However, the actual outflows as a result of the obligations may differ from such estimates. Provisions mainly relate to restructuring, customer and supplier-related provisions, warranty commitments, cash-settled share-based payments, claims or obligations as a result of patent infringement, and other litigations. 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. Curtailment gains and losses on defined benefit plans are reported as part of the net restructuring costs when the restructuring provision is raised for the underlying program. Customer-related 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. The loss is calculated based on the lower of the unavoidable costs to fulfill a contract and the exit penalty. The unavoidable cost includes both the incremental and allocated costs to fulfill the contract. Supplier-related provisions relate to contractual commitments mostly relating to inventories. The provision is based on a risk assessment comparing the forecasted sales volumes with the committed inventory levels. If the contractually committed inventory is assessed to be at risk of not being met, a provision is raised equal to the best estimate of the expected obsolescence or the contractual fee. 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. Share-based payment provision relates to cash-settled share-based programs. Refer to the accounting policy under “Cash-settled plans.” Other provisions relate mainly to patent infringements, litigations, and other provisions which do not fall within the defined categories. 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 the Company’s monitoring of patent-related cases in the relevant legal systems. In the ordinary course of business, the Company is subject to proceedings, lawsuits, and other unresolved claims. 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. Present or possible obligations that do not meet the provision recognition criteria 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 acquired acquisition-by-acquisition non-controlling non-controlling The acquired entity is consolidated into the Group results from the date of acquisition. Accordingly, the consolidated stockholders’ equity includes equity in subsidiaries, joint ventures, and associated companies earned only after their acquisition.
Associated companies	Associated companies Investments in associated companies is when the Company has significant influence and the ability 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%. Associated companies are accounted for in accordance with the equity method. Any change in other comprehensive income of the associated companies is presented as part of other comprehensive income. If the Company’s interest in an associated company is nil, the Company does not recognize its part of any future losses. Provisions related to obligations for such an interest are recognized.
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 securities are recognized on the settlement date. Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership. The Company sells its receivables with the expectation that all derecognition criteria are fully satisfied thereby no material asset or liability is retained. 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 cash flow characteristics of the asset and the business model in which it is held. 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 using observable inputs such as market prices for implied volatility, foreign exchange and interest rates. Where there are no
Financial assets at amortized cost	Financial assets at amortized cost Interest bearing assets, including cash equivalents, held with the objective to collect contractual cash flows, are classified as amortized cost assets. These include securities and deposits not managed on a fair value basis and loans
Financial assets at fair value through other comprehensive income (FVOCI)	Financial assets at fair value through other comprehensive income (FVOCI) Trade receivables are classified as FVOCI because the business model is primarily to collect, with occasional sales. Sale of trade receivables are made when the liquidity need arises and competitive prices are available for such a sale.
Financial assets at fair value through profit or loss (FVTPL)	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. Derivatives are classified as FVTPL, unless they are designated as hedging instruments for the purpose of hedge accounting. Derivatives assets and liabilities are offset where there is legally enforceable right to offset non-current Interest-bearing assets including investment in securities and money market funds are classified as FVTPL where they are either held in a portfolio managed on a fair value basis or held for short-term liquidity purposes. Customer finance receivables are classified as FVTPL because they are primarily held for sale. These assets are presented on the balance sheet based on their maturity date (i.e., those with a maturity longer than one year are presented as non-current). non-current Gains or losses arising from changes in the fair values of investment in shares and participations are presented in the income statement within other operating income. Gains and losses on derivatives are presented in the income statement as follows: Gains and losses on derivatives used to hedge foreign exchange risks are presented within net foreign exchange gains and losses. Gains and losses on interest rate derivatives used to hedge financial assets and liabilities are presented in financial income and financial expense, respectively. Gains and losses on revaluation of customer financing receivables are presented in the income statement as selling expenses. Gains and losses arising from changes in the fair values of all other assets in the FVTPL category are presented in the income statement within financial income. 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). The Company adopts a simplified approach for trade receivables and contract assets whereby allowances 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 on a separate line in the income statement. When there is no reasonable expectation of collection, the asset is written off. Other amortized costs assets are mainly investment grade assets deemed to be low risk hence credit risk is assumed not to have increased significantly since initial recognition. If the Company identifies evidence of significant change in credit risk on the assets, lifetime ECL is used to calculate allowance on the asset. Default is deemed if the asset is more than 90 days past due, after which lifetime ECL is also used to calculate allowance on the asset.
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.
Trade payables	Trade payables Trade payables are recognized as amortized cost liabilities. Some suppliers sell their Ericsson receivables to banks and the Company The Company the Company’s the Company’s
Borrowings	Borrowings Borrowings issued by the Parent Company are designated FVTPL where they are managed on a fair value basis. These are long term borrowings held in an Asset and liability management portfolio where the interest rate risk is managed by matching fixed and floating interest rates of interest-bearing balance sheet items. Changes in fair value of this portfolio are recognized in financial expense, except for changes in fair value due to changes in credit risk which are recognized in other comprehensive income. Borrowings not managed on a fair value basis are classified as amortized cost liabilities. These include revolving credit facilities and commercial papers program which are used for short term liquidity purposes and cash collaterals received. Borrowings are presented 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.
Cash flow hedge accounting	Cash flow hedge accounting The Company has the following recurring hedge programs: a) Certain customer contracts where a fluctuation in the USD/SEK foreign exchange (FX) rate would significantly impact net sales. These contracts are multi-year contracts denominated in USD with highly probable payments at fixed points in time. b) Highly probable forecasted sales denominated in USD in Ericsson AB ( For both programs, the Company enters into FX forward contracts that match the terms of the foreign exchange exposure as closely as possible and designates 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 designates changes in forward rates as the hedged risk. When applying hedge accounting, the effective portion of changes in the fair value of derivatives that is designated and qualifies 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. In addition to the recurring hedge programs, cash flow hedge is also designated for certain highly probable acquisition expected to be transacted in foreign currencies. FX derivatives are used as hedging instruments, at a hedge ratio of 1:1. The Company designates changes in forward rates as the hedged risks. The accounting is similar to that described for the cash flow hedge above, except that upon recognition of the hedged acquisition, the cumulative amount in the cash flow hedge reserve is released and recognized as a basis adjustment to the goodwill.
Post-employment benefits	Post-employment benefits Pensions and other post-employment benefits are classified as either defined contribution plans or defined benefit plans. These include gratuity plans, medical plans and leave encashment plans which are expected to be provided to employees over a period longer than 12 months. 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 for such bonds such as Sweden the market yields on government bonds are used. The calculations are based upon actuarial assumptions that are updated annually. 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, referred to as ‘asset ceiling’. The pension asset is presented as Other Financial assets, non-current. Interest cost on the defined benefit obligation and interest income on plan assets is calculated as a net interest amount and presented within Financial expenses. Curtailment gains and losses due to restructuring programs are recognized 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 relates to remuneration to employees, including key management personnel and the Board of Directors, and could be settled in either shares or cash. The majority of the granted share-based programs are cash-settled, except for programs for the Executive Team and the long-term variable compensation (LTV) 2023 program. These programs are share-settled. Share-settled plans will be settled in the Parent Company Class B shares provided the market-related and non-market-related Share-settled plans Compensation costs are recognized during the vesting period, based on the fair value of the Ericsson share at the grant date, and considers performance and market-related vesting conditions. All plans have service conditions, while some have performance and market-related vesting conditions. Examples of performance conditions could be revenue and profit targets and market conditions relate to the development of the Parent Company’s share price in relation to a group of reference shares. For further detailed information, see note G3 “Share-based compensation.” 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 the 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, and accounted for as a provision. Otherwise the accounting is similar to a share-settled plan. Cash-settled plans relating to employees’ share-based payment programs have similar vesting criteria to share-settled plans. All plans have service conditions, while some have performance and market-related vesting conditions. Up to and including 2022, non-executive directors For further detailed
Income taxes	Income taxes Income taxes in the consolidated financial statements include both current and deferred taxes. Income taxes do not include VAT, sales/use taxes, or other taxes not based on taxable profits. 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. Current income tax and deferred taxes are measured at the tax rate that is expected to be applied based on the tax laws that have been enacted or substantially enacted for the reporting period in the corresponding jurisdiction. Deferred tax is recognized for temporary differences between the book values of assets and liabilities and their tax values for unused tax loss carry-forwards and for unused tax credits. 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, tax loss carry-forwards and tax credits 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 temporary differences when it is probable that the temporary difference will not reverse in the foreseeable future. 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.
Statement of cash flows	Statement of cash flows The statement of cash flows is prepared using the indirect method. Cash flows from foreign subsidiaries are translated at the average exchange rate during the period. For practical reasons, the Company uses the closing rate of the previous month end as approximation of the period average exchange rate. 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. Movements in cash collaterals received and bank borrowings less than 3 months (used for short-term liquidity purposes) are presented net within “Other financing activities”. 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.
Government grants	Government grants Government grants are recognized when there is reasonable assurance that the Company will comply with the conditions attached to them and the grants will be received. Government grants received are mainly recognized in the consolidated income statement as a deduction against the related expense.
Climae-related considerations	Climate The Company has performed an analysis of how different climate scenarios could affect the Company and its value chain. The analysis did not identify any short-term material financial risks or changes to significant accounting policies and accounting estimates. In the middle to long-term horizon, carbon pricing and potential scarcity in raw materials used in products and equipment affecting actors in the upstream value chain, as well as disruptions in supply due to severe weather events have been identified as emerging risks. The Company intends to refine the analysis and assess climate-related financial implications in more granularity in coming years.
