Summary Of Significant Accounting Policies [Abstract]
A1 Significant accounting policies	Section A – Basis of presentation Significant 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, 2021 have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the IASB, and as endorsed by the EU and RFR 1 “Additional rules for Group Accounting,” related interpretations issued by the Swedish Financial Reporting Board (Rådet för finansiell rapportering), and the Swedish Annual Accounts Act. For the financial reporting of 2021, the Company has applied IFRS as issued by the IASB (IFRS effective as per December 31, 2021). There is no difference between IFRS effective as per December 31, 2021, and IFRS as endorsed by the EU, nor is RFR 1 related interpretations issued by the Swedish Financial Reporting Board (Rådet för finansiell rapportering) or the Swedish Annual Accounts Act in conflict with IFRS, for all periods presented. The financial statements were approved by the Board of Directors on March 3, 2022. 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, 2021, can be found in the end of this note. The preparations for the adoption of new standards and interpretations not adopted in 2021 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 and loss (FVTPL), financial instruments classified as fair value through other comprehensive income (FVOCI) and plan assets related to defined benefit pension plans. Assets acquired under business combinations are fair valued at initial recognition. 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. Changes to the presentation in the financial statements Operating income has been renamed as EBIT (Earnings before financial items and income tax) and Operating margin as EBIT margin. The definitions of EBIT and EBIT margin remains unchanged. From 2021 current tax assets and current tax liabilities are presented as separate line items in the consolidated balance sheet. Previously current tax assets were included in other current receivables and current tax liabilities were included in other current liabilities. Prior year have been represented. The following changes were made to the presentation of the Consolidated statement of cash flows in 2021: - Interests and tax cash flows are presented as separate line items within the “Cash flow from operating activities.” Previously, interests and tax cash flows were subsumed within various lines in the sections “Adjustments to reconcile net income to cash” and “Changes in operating net assets,” and only disclosed in note H3 “Statement of cash flow.” Prior years have been represented and there is no impact on cash flows from operating activities. - Net movements in cash collaterals received and bank borrowings less than 3 months (used for short term liquidity purposes) are presented within “Other financing activities” since these balances fluctuate over a short duration, therefore it is neither practical nor useful to present their gross movements on the cash flow statement. Cash flow from financing activities in prior years have been restated accordingly, resulting in a reclassification between the lines “Proceeds from issuance of borrowings,” “Repayment of borrowings” and “Other financing activities,” with no net effect on total cash flow from financing activities. - Purchases and sales of interest-bearing securities are presented on a gross basis to improve the visibility of cash flows. Cash flow from investing activities in prior years have been restated accordingly, resulting in new lines for “Purchase of interest-bearing securities” and “Sale of interest-bearing securities”. Basis of consolidation and composition of the Group The consolidated financial statements are prepared in accordance with the purchase method. Accordingly, consolidated stockholders’ equity includes equity in subsidiaries, joint ventures and associated companies earned only after their acquisition. Subsidiaries are all companies for which Telefonaktiebolaget LM Ericsson, directly or indirectly, is the parent. To be classified as a parent, Telefonaktiebolaget LM Ericsson, directly or indirectly, must control another company which requires that the Parent Company has power over that other company, is exposed to variable returns from its involvement and has the ability to use its power over that other company. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that such control ceases. Intra-group balances and any unrealized income and expense arising from intra-group transactions are fully eliminated in preparing the consolidated financial statements. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. The Company is composed of 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 transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at period-end Changes in the fair value of monetary securities denominated in foreign currency classified as fair value through other comprehensive income (FVOCI) are allocated between translation differences resulting from changes in the amortized cost of the security and other changes in the carrying amount of the security. Translation differences related to changes in the amortized cost are recognized in profit or loss, and other changes in the carrying amount are recognized in Other Comprehensive Income (OCI). Foreign 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. Group companies The results and financial position of all the group entities that have a functional currency different from the presentation currency are translated into the presentation currency as follows: Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet. Period income and expenses for each income statement are translated at period average exchange rates. All resulting net exchange differences are recognized as a separate component of Other comprehensive income (OCI). On consolidation, exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are accounted for in OCI. When a foreign operation is disposed of or sold, exchange differences that were recorded in OCI are recognized in the income statement as part of the gain or loss on sale. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and are translated at the closing rate. The Company is continuously monitoring the economies with high inflation, the risk of hyperinflation and potential impact on the Company. There is no significant impact due to any currency translation of a hyper-inflationary economy. Business and operations For further disclosure, see the notes under section B . Revenue recognition IFRS 15, “Revenue from Contracts with Customers” is a principle-based model of recognizing revenue from customer contracts. It has a five-step model that requires revenue to be recognized when control over goods and services are transferred to the customer. The following paragraphs describes the types of contracts, when performance obligations are satisfied, and the timing of revenue recognition. They also describe the normal payment terms associated with such contracts and the resulting impact on the balance sheet over the duration of the contracts. The vast majority of Ericsson’s business is for the sale of standard products and services. Standard products and services Products and services are classified as standard solutions if they do not require significant installation and integration services to be delivered. Installation and integration services are generally completed within a short period of time, from the delivery of the related products. These products and services are viewed as separate distinct performance obligations. This type of customer contract is usually signed as a frame agreement and the customer issues individual purchase orders to commit to purchases of products and services over the duration of the agreement. For further disclosure, see the notes under section D . Provisions Provisions are made when there are legal or constructive obligations as a result of past events and when it is probable that an outflow of resources will be required to settle the obligations and the amounts can be reliably estimated. When the effect of the time value of money is material, 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 and other obligations, 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. Provision for restructuring is recorded when the Company can reliably estimate the liabilities relating to the obligation. The estimate is based on the Company’s expected expenditure to settle the obligation and is adjusted when changes to the expenditure is known. 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. These contract loss estimates may include penalties under a loss contract. Supplier-related provisions consist of guarantees or claims by suppliers. A provision equal to the best estimate of the expected expenditure to settle the obligation is raised when the Company can reliably estimate the obligation and it is probable that there will be an outflow of resources required to settle the obligation. 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 litigations. 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. To the extent that the Company makes the judgment that an identified potential infringement will more likely than not result in an outflow of resources, the Company records a provision based on the Company’s best estimate of the expenditure required to settle with the counterpart. In the ordinary course of business, the Company is subject to proceedings, lawsuits, and other unresolved claims, including proceedings under laws and government regulations and other matters. These matters are often resolved over a long period of time. The Company regularly assesses the likelihood of any adverse judgments in or outcomes of these matters, as well as potential ranges of possible losses. Provisions are recognized when it is probable that an obligation has arisen, and the amount can be reasonably estimated based on a detailed analysis of each individual issue. Contingent liabilities Certain present obligations are not recognized as provisions as it is not probable that an economic outflow will be required to settle the obligations or the amount of the obligation cannot be measured with sufficient reliability, or there is a possible obligation arising from a past event, which will be confirmed by the occurrence or non-occurrence of a future uncertain event, not within the control of the Company. Such obligations are reported as contingent liabilities. For further detailed information, see note D2 “Contingent liabilities.” In note A2 “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied. 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 given, and liabilities incurred or assumed at the date of exchange, including any cost related to contingent consideration. Transaction costs attributable to the acquisition are expensed as incurred. The acquisition cost is allocated to acquired assets, liabilities, and contingent liabilities based upon appraisals made, including assets and liabilities that were not recognized on the acquired entity’s balance sheet, for example, intangible assets such as customer relations, brands, patents, and financial liabilities. Goodwill arises when the purchase price exceeds the fair value of recognizable acquired net assets. In acquisitions with non-controlling In case there is a put option for a non-controlling Non-controlling The Company treats transactions with non-controlling non-controlling non-controlling At acquisition, there is a choice on an acquisition-by-acquisition non-controlling non-controlling Joint ventures and associated companies When the Company ceases to have control, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest in an associate or financial asset. In addition, any amounts previously recognized in Other comprehensive income in respect of that entity are accounted for as if the Company had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in Other comprehensive income are reclassified to profit or loss. Joint ventures and associated companies are accounted for in accordance with the equity method. Under the equity method, the investment in the joint venture or associate is initially recognized at cost and the carrying amount is increased or decreased to recognize the investor’s share of the profit or loss of the investee after the date of acquisition. If the Company’s interest in an associated company is nil, the Company shall not, as prescribed in IFRS, recognize its part of any future losses. Provisions related to obligations for such an interest shall, however, be recognized in relation to such an interest. Investments in associated companies is, when the Company has significant influence and the power to participate in the financial and operating policy decisions of the associated company but is not in control or joint control over those policies. Normally, this is the case in voting stock interest, including effective potential voting rights, which stand at least at 20% but not more than 50%. The Company’s share of income before taxes is reported in item “Share in earnings of joint ventures and associated companies,” included in EBIT. This reflects the fact that these interests are held for operating rather than investing or financial purposes. Ericsson’s share of income taxes related to associated companies is reported under the line item “Income tax,” in the income statement. Unrealized gains on transactions between the Company and its joint ventures and associated companies are eliminated to the extent of the Company’s interest in these entities. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Shares in earnings of joint ventures and associated companies are included in consolidated equity since they are undistributed. They are reported in retained earnings in the balance sheet. Impairment testing, as well as recognition or reversal of impairment of investments in each joint venture and associated company, is performed in the same manner as for intangible assets other than goodwill. The entire carrying value of each investment, including goodwill, is tested as a single asset. See also description under “Intangible assets other than goodwill” below. If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in Other comprehensive income are reclassified to profit or loss where appropriate. In note A2, “Critical Accounting Estimates and Judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied. Financial 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. Separate assets or liabilities are recognized if any rights and obligations are created or retained in the transfer. The Company classifies its financial assets in the following categories: at amortized cost, at fair value through other comprehensive income (FVOCI), and at fair value through profit or loss (FVTPL). The classification depends on the cash flow characteristics of the asset and the business model in which it is held. Financial assets are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. The fair values of quoted financial investments and derivatives are based on quoted market prices or rates. If official rates or market prices are not available, fair values are calculated by discounting the expected future cash flows at prevailing interest rates. Valuations of foreign exchange options and Interest Rate Guarantees (IRG) are made by using the Black-Scholes formula. Inputs to the valuations are market prices for implied volatility, foreign exchange and interest rates. Financial assets at amortized cost Financial assets are classified as amortized cost if the contractual terms give rise to payments that are solely payments of principal and interest on the principal amount outstanding and the financial asset is held in a business model whose objective is to hold financial assets in order to collect contractual cash flows. These assets are subsequently measured at amortized cost using the effective interest method, minus impairment allowances. Interest income and gains and losses from financial assets at amortized cost are recognized in financial income. Financial assets at fair value through other comprehensive income (FVOCI) Assets are classified as FVOCI if the contractual terms give rise to payments that are solely payments of principal and interest on the principal amount outstanding and the financial asset is held in a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets. These assets are subsequently measured at fair value with changes in fair value recognized in other comprehensive income (OCI), except for effective interest, impairment gains and losses and foreign exchange gains and losses which are recognized in the income statement. Upon derecognition, the cumulative gain or loss in OCI is reclassified to the income statement. Financial assets at fair value through profit or loss (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 set-off, 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). ECLs are the differences between all contractual cash flows that are due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at the original effective interest rate. 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 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. Default is deemed if the asset is more than 90 days past due, after which lifetime ECL is 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. Borrowings Borrowings issued by the Parent Company are designated FVTPL because they are managed on a fair value basis. Changes in fair value are recognized in financial expense, except for changes in fair value due to changes in credit risk which are recognized in other comprehensive income. Borrowings not issued by the Parent Company are classified as amortized cost liabilities. They are initially recognized at fair value, net of transaction costs incurred. These borrowings are subsequently measured at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method. Borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date. Trade payables Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method. Cash flow hedge accounting The Company identified certain customer contracts where a fluctuation in the USD/SEK foreign exchange (FX) rate would significantly impact net sales and EBIT recorded from the contracts. These contracts are multi-year contracts denominated in USD with highly probable payments at fixed points in time. 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 ies 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 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. Under a defined contribution plan, the Company’s only obligation is to pay a fixed amount to a separate entity (a pension trust fund) with no obligation to pay further contributions if the fund does not hold sufficient assets to pay all employee benefits. The related actuarial and investment risks fall on the employee. The expenditures for defined contribution plans are recognized as expenses during the period when the employee provides service. Under a defined benefit plan, it is the Company’s obligation to provide agreed benefits to current and former employees. The related actuarial and investment risks fall on the Company. The present value of the defined benefit obligations for current and former employees is calculated using the Projected Unit Credit Method. The discount rate for each country is determined by reference to market yields on high-quality corporate bonds that have maturity dates approximating the terms of the Company’s obligations. In countries where there is no deep market in such bonds, the market yields on government bonds are used. The calculations are based upon actuarial assumptions that are updated annually. Actuarial assumptions are the Company’s best estimate of the variables that determine the cost of providing the benefits. When using actuarial assumptions, it is possible that the actual results will differ from the estimated results or that the actuarial assumptions will change from one period to another. These differences are reported as actuarial gains and losses. They are, for example, caused by unexpectedly high or low rates of employee turnover, changed life expectancy, salary changes and changes in the discount rate. Actuarial gains and losses and gains and losses from remeasurement of plan assets are recognized in OCI in the period in which they occur. The Company’s net liability for each defined benefit plan consists of the present value of pension commitments less the fair value of plan assets and is recognized net on the balance sheet. When the result is a net benefit to the Company, the recognized asset is limited to the present value of any future refunds from the plan or reductions in future contributions to the plan, referred to as ‘asset ceiling’. Interest cost on the defined benefit obligation and interest income on plan assets is calculated as a net interest amount by applying the discount rate to the net defined benefit liability. Current service cost relating to employee service is recognised in the profit and loss in the period. Past service cost relating to plan amendments or curtailment is recognized immediately in the period it occurs. Swedish special payroll tax is accounted for as a part of the pension cost and the pension liability respectively. Payroll taxes related to actuarial gains and losses are included in determining actuarial gains and losses, reported under OCI. In note A2, “Critical accounting estimates and judgments” further disclosure is presented in relation to key sources of estimation uncertainty. Share-based compensation to employees and the Board of Directors Share-based compensation is related to remuneration to employees, including key management personnel and the Board of Directors and could be settled either in shares or cash. Under IFRS, a company shall recognize compensation costs for share-based compensation programs based on a measure of the value to the company of services received under the plans. For share-settled plans, a corresponding increase in equity shall be recognized. As from 2017 the granted share-based programs are cash-settled, except for programs for the Executive Team. Those programs are share-settled. Share-settled plans Compensation costs are recognized during the vesting period, based on the fair value of the Ericsson share at the grant date, as well as considering performance – and market conditions. Examples of performance conditions could be revenue and profit targets while market conditions relate to the development of the Parent Company’s share price in relation to a group of reference shares. All plans have service conditions and some of them have performance or market conditions. For share-settled plans, a corresponding increase in equity shall be recognized. The reason for this IFRS accounting principle is that compensation cost for a share-settled program is a cost with no direct cash flow impact. 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.

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 at change of strategy or restructuring. Judgments for accounting policies to be applied as well as estimates may also be impacted due to this. Following are the most important accounting policies subject to such judgments and the key sources of estimation uncertainty that the Company believes could have the most significant impact on the reported results and financial position. The information in this note is grouped as per: – Key sources of estimation uncertainty – Judgments management has made in the process of applying the Company’s accounting policies. Revenue recognition Key sources of estimation uncertainty The Company uses estimates and judgments in determining the amount and timing of revenue under IFRS 15, “Revenue from Contracts with Customers,” particularly when determining the transaction price and its allocation to performance obligations identified under the contract. Transaction price may consist of variable elements such as discounts, performance related price and contract penalties. Transaction price, including variable considerations, is estimated at the commencement of the contract (and periodically thereafter). Judgment is used in the estimation process based on historical experience with the type of business and customer. 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. IFRS 15 also requires revenue to be allocated to each performance obligations by reference to their standalone selling prices. The Company considers that an adjusted market assessment approach should be used to estimate stand-alone selling prices for its products and services for the purposes of allocating transaction price. These estimates comprised of prices set for similar customer and circumstances, adjusted to reflect appropriate profit margins for the market. Estimates are used to determine discounts that relate specifically to each performance obligation, thus impacting th e Judgments made in relation to accounting policies applied Management applies judgment when assessing the customer’s ability and intention to pay in a contract. The assessment is based on the latest customer credit standing and the customer’s past payment history. This assessment may change during the contract execution, and if there is evidence of deterioration in the customer’s ability or intention to pay, then under IFRS 15 no further revenue shall be recognized until the collectability criteria is met. Conversely, this assessment may also change favorably over time, upon which revenue shall now be recognized on a contract that did not initially meet the collectability criteria. Management also applies judgment in assessing criteria for contract combination. Master purchase agreement can cover a number of different businesses with the same customer and judgment is applied to assess if prices relating to the different businesses are highly dependent, in which case, contracts relating to such businesses shall be combined and the total transaction price allocated to each performance obligation based on estimated stand-alone selling prices. Judgment can also be applied on contract amendments related to prior performance obligations, in which case, the judgment is related to assess if part of the transaction price shall be applied retrospectively. Revenue for standard products shall be recognized when control over the equipment is transferred to the customer at a point in time. This assessment shall be viewed from a customer’s perspective considering indicators such as transfer of titles and risks, customer acceptance, physical possession, and billing rights. Judgment may be applied in determining whether risk and rewards have been transferred to the customer and whether the customer has accepted the products. Often all indicators of transfer of control are assessed together and an overall judgment formed as to when transfer of control has occurred in a customer contract. Revenue for customized solutions shall be recognized over time if progress of completion can be reliably measured and enforceable right to payment exists over the duration of the contract. The progress of completion is estimated by reference to the output delivered such as achievement of contract milestones and customer acceptance. Judgments are applied when determining the appropriate revenue milestones that best reflect the progress of completion and are aligned with key acceptance stages within the contract. 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 have historically had similar loss patterns. The amount of ECLs is sensitive to changes in the 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. Management review of current and future conditions is based on latest observable economic updates and our internal assessment of the potential impact on our customers. Total allowances for expected credit losses as of December 31, 2021 were SEK 2.4 (2.5) billion or 4% (5%) 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. Inventory valuation Key sources of estimation uncertainty Inventories are valued at the lower of cost and net realizable value. Estimates are required in relation to forecasted sales volumes and inventory balances. In situations where excess inventory balances are identified, estimates of net realizable values for the excess volumes are made. Inventory allowances for estimated losses as of December 31, 2021, amounted to SEK 3.6 Classification in relation to companies owned by less than 100% Judgment in relation to the classification of ownership that is less than 100% requires the Company to judge if the ownership shall be classified as a subsidiary, joint venture, associated company, or financial asset. See “Basis of consolidation and composition of the Group” as well as “Joint ventures and associated companies” under note A1 “Significant accounting policies” for a background. Financial assets refer to the ownerships that neither are subsidiaries nor JV/associated companies. Acquired 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 assets. After initial recognition, impairment testing is performed whenever there is an indication of impairment, in addition, goodwill impairment testing is performed once per year. Negative deviations in actual cash flows compared to estimated cash flows as well as new estimates that indicate lower future cash flows might result in recognition of impairment charges. Impairment losses for intangible assets and goodwill amounted to SEK -0.3 (-0.1) At December 31, 2021, the carrying amount of acquired intellectual property rights and other intangible assets amounted to SEK 42.0 (39.8) billion, including goodwill of SEK 38.2 (34.9) billion. For further discussion on goodwill, see note A1 “Significant accounting policies.” Estimates related to acquired intangible assets are based on similar assumptions and risks as for goodwill. For more information, see note C1 “Intangible assets.” Judgments made in relation to accounting policies applied At initial recognition and subsequent remeasurement, management judgments are made, both for key assumptions and regarding impairment indicators. In the purchase price allocation made for each acquisition, the purchase price is assigned to the identifiable assets, liabilities, and contingent liabilities based on fair values for these assets. Any remaining excess value is reported as goodwill. This allocation requires management judgment as well as the definition of cash-generating units for impairment testing purposes. Other judgments might result in significantly different results and financial position in the future. Leases Key sources of estimation uncertainty At initial recognition and subsequent remeasurement, management estimates are made for the term applied in a lease contract. The outcome of these estimates may turn out not to match the actual outcome of the lease and may have an adverse effect on the right-of-use Judgments made in relation to accounting policies applied Lease contracts may give the lessee the right to shorten or extend a contract. Under such contracts management judgement of the lease term is required. 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. An incremental borrowing rate is used in discounting of the lease liabilities and requires judgement to reflect the rate of interest that would have to be paid to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use right-of Provisions Key sources of estimation uncertainty Provisions mainly related to estimates for onerous contracts with customers and suppliers. Onerous customer contract provision includes estimates of costs to be incurred based on the latest conditions and progress on the contract. Assumptions on the probable outcomes of revenue and costs, which may include costs of potential compensation or penalties on exit, are revised regularly based on the latest available information, and the provision is remeasured accordingly. Other sources for estimation uncertainty are restructuring program execution (cost and timing), and outcomes relating to patent and other litigation. Litigations and disputes may continue over several years and therefore there is uncertainty in the final outcome and expected settlement. Provisions are regularly reassessed based on the latest information available and are adjusted to reflect the Company’s best estimate of the eventual outcome. This means there may be changes to the provision values over time. At December 31, 2021, provisions amounted to SEK 9.5 (10.5) billion. For further detailed information, see note D1 “Provisions.” Judgments made in relation to accounting policies applied Whether a present obligation is probable or not requires judgment. The nature and type of risks for these provisions differ and management’s judgment is applied regarding the nature and extent of obligations in deciding if an outflow of resources is probable or not. Further judgment is required in determining the value of the obligation as this is based on the Company’s best estimate as to the expected future expenditure required to settle the obligation. Supplier payments program Judgments made in relation to accounting policies applied With the aim of increasing working capital efficiency, Ericsson continuously renegotiates payment days with suppliers. The negotiations with suppliers for payment days is an integral part of the procurement activities. Some suppliers sell their Ericsson receivables to banks and Ericsson can if requested introduce a bank interested in purchasing such receivables. Ericsson does not pay or receive a fee, nor provide additional security under the program. This arrangement does not lead to any significant change in the nature or function of Ericsson’s liabilities because the supplier invoices are considered part of working capital used in Ericsson’s normal operating cycle. The maximum credit period agreed with any supplier does not exceed six months. Therefore, these liabilities remain classified as trade payables with separate disclosure in the notes, see note B8 “Trade payables.” Contingent liabilities Key sources of estimation uncertainty As disclosed under ‘Provisions’ the same type of uncertainty exists for contingent liabilities, specifically relating to the valuation of the possible obligations. Contingent liabilities mainly relate to estimates for litigation, tax ligitation, and pension guarantees. As the contingent liabilities will only be confirmed in the future based on the resolution of the litigation or dispute, management is required to estimate the possibility of an adverse outcome occurring and potential settlement value. Given that there are a number of potential obligations, a contingent liability may arise and/or expense (provision) may have to be recognized at a later stage. Judgments made in relation to accounting policies applied As disclosed under note A1, “Significant accounting policies” a present obligation that is not likely to result in an economic outflow or a possible obligation which will be confirmed by the occurrence or non-occurrence Pensions and other post-employment benefits Key sources of estimation uncertainty Accounting for the costs of defined benefit pension plans and other applicable post-employment benefits is based on actuarial valuations, relying on key estimates for discount rates, future salary increases, employee turnover rates and mortality tables. The discount rate assumptions are based on rates for high-quality fixed-income investments with durations as close as possible to the Company’s pension plans. In countries where there is not a deep market in high-quality corporate bonds, the market yields on government bonds shall be applied. Judgment is applied in determining the deepness of the high-quality corporate bond market in each country. The impact of applying an alternative discount rate based on Swedish covered bonds is disclosed in note G1, “Post-employment benefits.” At December 31, 2021, defined benefit obligations for pensions and other post-employment benefits amounted to SEK 113.5 (108.2) billion and fair value of plan assets to SEK 81.4 (73.6) billion. For more information on estimates and assumptions, see note G1 “Post-employment benefits.” Deferred taxes Key sources of estimation uncertainty Deferred tax assets and liabilities are recognized for temporary differences and for tax loss carry-forwards. The valuation of temporary differences and tax loss carry-forwards is based on management’s estimates of future taxable profits in different tax jurisdictions against which the temporary differences and loss carry-forwards may be utilized. These estimates are primarily based on business plans for the Company´s estimated outcome of deductibility in relation to larger provisions. As prescribed in IFRIC 23 estimates are made in relation to uncertain tax positions in a limited number of countries. Estimates are made for any expected changes in tax legislation with a potential material impact. The largest amounts of tax loss carry-forwards are reported in Sweden, with an indefinite period of utilization (i.e. with no expiry date), except for withholding taxes that expire after five years. For further information, see note H1 “Taxes.” At December 31, 2021, the value of deferred tax assets amounted to SEK 23.1 (26.3) billion. The deferred tax assets related to loss carry-forwards are reported as non-current Accounting for income tax, value added tax, and other taxes Key sources of estimation uncertainty Accounting for these items is based upon evaluation of taxable income, value added and other tax rules in all jurisdictions where the profits arise. 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. COVID-19 The COVID-19 COVID-19 The Company continually assesses the business performance and profitability for changes in expected future cash flows which could impact recoverability of assets such as deferred tax assets and intangible assets. As with prior year, the Company concluded there is no evidence of material changes to recoverability risk of business assets as a direct effect of COVID-19. Comments on areas of financial statements affected are in the following notes: C1 “Intangible assets,” “D4 Contractual obligations,” F1 “Financial Risk Management,” and H1 “Taxes.”

The assumptions regarding industry-specific market drivers and market growth are based on industry sources as input to the projections made within the Company for the development 2022–2026 for key industry parameters: – By 2026, about 35 years after the introduction of digital mobile technology, it is predicted that there will be 8.8 billion mobile subscriptions (excl. Cellular IoT). – The number of mobile subscriptions is estimated to grow from around 8.3 billion by the end of 2022 to around 8.8 billion by the end of 2026. Out of all mobile subscriptions, 7.7 billion will be associated with a smartphone. – The number of 5G subscriptions is forecasted to reach 3.7 billion (excl. Cellular IoT) by the end of 2026. – By 2026, about 39 billion connected devices are forecasted, of which over 27 billion will be related to Internet of Things, IoT. Connected IoT devices including connected cars, machines, meters, sensors, point-of-sale – Cellular IoT is predicted to grow from 2.4 billion devices in 2022 to 4.8 billion devices in 2026. – Mobile data traffic volume is estimated to increase by around three times in the period 2022–2026. The mobile traffic is driven by smartphone users and video traffic. Smartphone traffic will grow by around three times, and mobile video traffic is forecasted to grow by around 30% annually through 2026 to account for approximately 75% of all mobile data traffic. The assumptions are also based upon information gathered in the Company’s long-term strategy process, including assessments of new technology, the Company’s competitive position and new types of business and customers, driven by the continued integration of telecom and data. The business plans for all CGUs, except Cradlepoint and Emodo are based on specific estimates for the five-year forecast period, 2022-2026. The CGUs Cradlepoint and Emodo use a ten-year top-line 10-year All CGUs use a nominal annual growth rate of 1.5% (1.0%) per year after the forecast period An after-tax after-tax Post-tax CGU 2021 2020 Networks 7.5 8.0 Digital Services 8.0 8.0 Managed Services 8.0 8.0 Cradlepoint 10.0 N/A iconectiv 9.0 8.0 Emodo 12.0 12.0 Red Bee Media 9.5 8.0 There are no reasonable possible change in key assumptions The Company’s discounting is based on after-tax after-tax before-tax before-tax The Company has considered the effect of the COVID-19

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 favourable 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 2021, the total provision value is SEK 9.5 (10.5) billion, of which SEK 3.7 (2.9) billion is classified as non-current. For more information, see note A1 “Significant accounting policies” and note A2 “Critical accounting estimates and judgments” for key estimation uncertainty regarding timing and amount. 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. The scope of the structural efficiency measures involves service delivery, supply and manufacturing, R&D, and selling and administration expenses. Restructuring provisions are recognized based on the expected costs of the respective restructuring programs and primarily consist of personnel costs. Estimation uncertainty exists regarding the execution of the restructuring programs, which may impact the expected timing and realization of costs. Restructuring provisions are reviewed and adjusted regularly based on management’s best estimate. The expected timing and amount of outflows are dependent on whether the plan execution is in line with management’s assessment. The majority of the restructuring provision will be utilized within 1 year. For more information about the restructuring charges booked in the income statement, see note B3 “Expenses by nature.” Customer-related provisions Customer-related provisions mainly consist of provisions for loss-making customer contracts. To measure the customer-related provisions, management estimates the unavoidable costs to fulfil the obligations under the customer contract. If the exit penalty is lower than the estimated costs to fulfil the contract, then the provision value is limited to the exit penalty value. The unavoidable costs to fulfil 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 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 forecast and any excess is provided for based on an assessment of the risk of obsolescence. Therefore, estimation uncertainty exists regarding the forecast and expected usage as 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 over 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

D2 Contingent liabilities	Contingent liabilities Contingent liabilities 2021 2020 Contingent liabilities 1,614 1,198 Total 1,614 1,198 Contingent liabilities mainly relate to pensions, litigations and tax litigations in subsidiaries. Contingent liabilities assumed by the Company include guarantees of loans to other companies of SEK 16 (15) million. All ongoing legal and tax proceedings have been 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 es timation uncertainty and (ii) the decision made in relation to accounting policies applied. On October 4, 2021, Ericsson asked the U.S. District Court for the Eastern District of Texas for a declaration that Ericsson has, in its negotiations with Apple, complied with its FRAND commitment and all other applicable laws and policies that would affect the terms of Ericsson’s and Apple’s prospective license. On December 17, 2021, Apple filed a responsive case against Ericsson in the U.S. District Court for the Eastern District of Texas alleging, among other things, that Ericsson breached obligations associated with the licensing of its standard essential patents under FRAND terms. The filing of lawsuits, complaints and other proceedings, when parties take legal action over a patent license agreement renewal, is standard and consequently additional lawsuits, complaints and other proceedings, may follow. See also note H6 “Events after reporting period.” 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 investigation. The CCI opened similar investigations against Ericsson in January 2014 based on claims made by Intex Technologies (India) Limited and, in 2015, based on a now settled claim from iBall. Ericsson has challenged CCI’s jurisdiction in these cases before the Delhi High Court and is awaiting final appellate decision by 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. In October 2021, Ericsson received correspondence from the US Department of Justice (DOJ) stating its determination that the Company had breached its obligations under its Deferred Prosecution Agreement (DPA) by failing to provide certain documents and factual information. The Company cannot provide further detail about the determination by the DOJ or predict the outcome of the resolution of this matter at this time. Hence it is not possible to reliably estimate potential future cash outflows in resolving the matter. See also note H6 “ Events after reporting period.” The above matters relating to Apple, Micromax, SAMR and the DOJ have not been included in the contingent liability amount disclosed in the table.

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 capitalize on business opportunities. The Company’s overall capital structure should support the financial targets. The capital structure is managed by balancing equity, debt financing and liquidity in such a way that the Company can secure funding of operations at a reasonable cost of capital. Regular borrowings are complemented with committed credit facilities to give additional flexibility to manage unforeseen funding needs. The Company strives to deliver strong free cash flow. The Company’s capital objectives are: – Strong free cash flow before M&A – Positive net cash position – Investment grade rating by Moody’s (Baa3), Standard & Poor’s (BBB-) (BBB-). Capital objectives-related information, SEK billion 2021 2020 Free cash flow before M&A 1) 32.1 22.3 Positive net cash 1) 65.8 41.9 Credit rating Fitch BBB-, stable BBB-, stable Standard & Poor’s BBB-, stable BBB-, stable Moody´s Ba1, stable Ba1, stable 1) For more information about the measures, see Alternative performance measures and Financial terminology. The Company has a treasury and customer finance function with the principal role to ensure that appropriate financing is in place through loans and committed credit facilities, actively managing the Company’s liquidity as well as financial assets and liabilities, and managing and controlling financial risk exposures in a manner consistent with underlying business risks and financial policies. The customer finance function may arrange suitable third-party financing solutions for customers to support 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 – Refinancing risk – Market price risk in own and other equity instruments. The Board of Directors has established risk limits for defined exposures to foreign exchange and interest rate risks as well as to political risks in certain countries. For further information about accounting policies, see note A1 “Significant accounting policies.” Foreign exchange risk The Company is a global company with sales mainly outside Sweden. Sales and incurred costs are to a large extent denominated in currencies other than SEK and therefore the financial results of the Company are impacted by currency fluctuations. The Company reports the financial statements in SEK. Movements in exchange rates between currencies that affect these statements are impacting the comparability between periods. Line items, primarily sales, are impacted by translation exposure incurred when converting foreign entities’ financial statements into SEK. Line items and profitability, such as 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 change 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 2022 is USD 263 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 EBIT Transaction exposure relates to sales and cost incurred in non-reporting The Company has identified certain customer contracts where a fluctuation in the USD/SEK foreign exchange rate would significantly impact net sales and EBIT. 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%. 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. In order to spread the FX execution risk over the year, 14% of each of the next six months forecasted sales and purchases in EAB are hedged monthly. The hedged volumes are funded by internal loans from its parent company which are not hedged, therefore the FX impact on revaluation of the loan is recognized in net FX as incurred. The sensitivity of the FX impact is dependent on changes in foreign exchange rates, forecasts and seasonality. USD is the only currency being hedged. Outstanding loan at year-end d) Transaction risk impacting business combination The Group 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 revenues and expenses. Sensitivity analysis The Company uses the Value at Risk (VaR) methodology to measure foreign exchange and interest rate risks managed by the treasury function. This statistical method expresses the maximum potential loss that can arise with a certain degree of probability during a certain period of time. For the VaR measurement, the Company has chosen a probability level of 99% and a one-day 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 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 2021 was SEK 1.1 (0.5) million per basis point shift. Sensitivity to interest rate increase of 1 basis point, SEK million < 3M 3–12M 1–3Y 3–5Y >5Y Total Interest-bearing assets — — (4) (3) — (7) Interest-bearing liabilities 1) — — 1 1 5 7 Derivatives — 1 1 — — 2 Total — 1 (2) (2) 5 2 1) Borrowings are included as they are designated FVTPL.

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 2021 < 3 3 – 12 > 1 year Total Notional Amount (USD millions) 734 1,372 525 2,631 Average forward rate (SEK/USD) 8.79 9.05 8.35 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 2021. Credit risk Credit risk is divided into three categories: credit risk in trade receivables and contract assets, customer finance risk and financial credit risk, see note A1 “Significant accounting policies.” Credit risk in trade receivables and contract assets Credit risk in trade receivables and contract assets is governed by a policy applicable to all legal entities in the Company. The purpose of the policy is to: – Avoid credit losses through establishing internal standard credit approval routines in all the Company’s legal entities – Ensure monitoring and risk mitigation of defaulting accounts, i.e. events of non-payment – Ensure efficient credit management within the Company and thereby improve days sales outstanding and cash flow – Define escalation path and approval process for customer credit limits. The credit risk of all customers is regularly assessed. Through credit management system functionality, credit checks are performed every time a sales order is generated in the source system. These are based on the credit risk set on the customer. Credit blocks appear if past due receivables are higher than permitted levels. Release of a credit block requires authorization. Letters of credits are used as a method for securing payments from customers operating in emerging markets, in particular in markets with unstable political and/or economic environments. By having banks confirming the letters of credit, the political and commercial credit risk exposures to the Company are mitigated. 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. Since the onset of the COVID-19 COVID-19. Trade receivables and contract assets together amounted to SEK 55,905 (53,336) million as of December 31, 2021. Provisions for expected credit losses on trade receivables and contract assets amounted to SEK 2,398 (2,518) million as of December 31, 2021. Total past due > 360 days has increased but the expectation of collection from some customers has also improved, resulting in a lower allowance at year end. The Company’s write-offs have historically been low. During the year SEK 163 (136) million were written off due to the Company having no reasonable expectation of collection. Of these write-offs, SEK 0 (0) million are still subject to enforcement. Movements in allowances for impairment of trade receivables and contract assets 2021 2020 Opening balance 2,518 2,983 Increase / (decrease) in allowance 40 (118) Write-offs (163) (136) Translation difference 3 (211) Closing balance 1) 2,398 2,518 1) Of which SEK 1 (1) million relates to contract assets. The distribution of trade receivables and contract assets closely follows the distribution of the Company’s sales, see note B1 “Segment information.” The ten largest customers represented 47% (50%) of the total trade receivables and contract assets in 2021.

Prior to the approval of new facilities reported as customer finance, an internal credit risk assessment is conducted in order to assess the credit rating of each transaction for political and commercial risk. The credit risk analysis is made by using an assessment tool, where the political risk rating is identical to the rating used by all Export Credit Agencies within the OECD. The commercial risk is assessed by analysing a large number of parameters, which may affect the level of the future commercial credit risk exposure. The output from the assessment tool for the credit rating also includes an internal pricing of the risk. This is expressed as a risk margin per annum over 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, 2021, the total amount payable to the Company under customer finance credits was SEK 5,239 (5,262) million. The carrying value of these assets was SEK 3,287 (3,137) million as of December 31, 2021. Customer finance is arranged for infrastructure projects in different geographic markets. As of December 31, 2021, there were a total of 81 (72) customer finance arrangements originated by or guaranteed by the Company. The five largest facilities represented 70% (75%) of the customer finance exposure in 202 Security arrangements for customer finance facilities may include pledges of equipment, pledges of certain assets belonging to the borrower and pledges of shares in the operating company. If available, third-party risk coverage is, as a rule, arranged. “Third-party risk coverage” means that a financial payment guarantee covering the credit risk has been issued by a bank, an export credit agency or an insurance company. All such institutions have been rated at least investment grade. A credit risk transfer under a sub-participation The table below summarizes the Company’s outstanding customer finance as of December 31, 2021 and 2020.

Fair value assessment of customer finance credits Customer finance risk exposures are held at fair value and are classified as Level 3 on the fair value hierarchy. The Credit Asset Management Team within Ericsson Credit AB, reporting to Head of Group Treasury and Customer Finance, has established a process with respect to measurement of fair values. The quarterly credit review uses an internal model to determine a commercial rating for each credit and for calculation of the fair value. The model is based on external credit rating, political/country rating and bank pricing. Regular monitoring of customer behavior is also a part of the internal assessment. Revaluation of customer finance (excluding effect of foreign exchange translation) amounted to a net gain in the income statement of SEK 350 (loss of 262) million in 2021, of which gain of SEK 347 (loss of 262) million relates to credits held as of December 31, 2021. This effect is presented within selling and administrative expenses and was mainly related to South East Asia Oceania and India.

Most of such financing has been successfully transferred to banks, hence the balance of customer finance receivables is in line with prior year. Financial credit risk Financial instruments carry an element of risk in that counterparts may be unable to fulfill their payment obligations. This exposure arises in the investments in cash, cash equivalents, interest-bearing securities and from derivative positions with positive unrealized results against banks and other counterparties. The Company mitigates these risks by investing cash primarily in high rated securities such as treasury bills, government bonds, commercial papers, and mortgage-covered bonds (see Liquidity risk section below). Separate credit limits are assigned to each counterpart in order to minimize risk concentration. All derivative transactions are covered by ISDA netting agreements to reduce the credit risk. For cross-currency swaps a Credit Support Annex (CSA) to ISDA is signed to further reduce the credit risk by exchanging collateral weekly against market value. The Company has also moved some derivative exposures to clearing counterparties with daily settlement of margins. At December 31, 2021, 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 0.3 (0.3) 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 current cash position is deemed to satisfy all short-term liquidity requirements.

Cash, cash equivalents and interest-bearing securities are mainly held in SEK. Refinancing risk Refinancing risk is the risk that the Company is unable to refinance outstanding debt under reasonable terms and conditions, or at all, at a given point in time. Debt financing is mainly carried out through borrowing in the Swedish and international debt capital markets. Bank financing is used for certain subsidiary funding and to obtain committed credit facilities.

The USD 2 billion facility replaces the previous USD 2 billion facility. 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. Unobservable input levels are generally determined via reference to observable inputs, historical observations or using other analytical techniques.

Unrealized gain of SEK million 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.

Market price risk in own shares and other listed equity investments The Company is exposed to fluctuations in its own share price through share-based compensation for employees and the Board of Directors. Some of the plans are share-settled and some are cash-settled as further disclosed in note A1 “Significant accounting policies”, note G2 “Information regarding members of the Board of Directors and Group management” and note G3 “Share-based compensation.” Share-based plans for employees The obligation to deliver shares under the 2019 and 2020 Long-Term Variable compensation programs (LTV) for the Executive Team is covered by holding Ericsson Class B shares as treasury stock. The cash flow exposure is managed through the holding of Ericsson Class B shares as treasury stock to be sold to generate funds, which also cover social security payments. A change in the share price will result in a change in social security charges, which represents a risk to the income statement. The cash flow exposure relating to the 2021 LTV program is not managed in the same manner. Cash-settled plans to employees and the Board of Directors In the case of synthetic share programs (a cash-settled program as defined in IFRS 2) to Board members and cash-settled plans to employees, the Company is exposed to risks in relation to own share price, both with regard to compensation expenses and social security charges. The obligations to pay compensation amounts under the synthetic share-based compensations to the Board of Directors and employees are covered by a provision in the balance sheet. For further information about LTV, the cash-settled plans to employees and the synthetic share-based compensations to the Board of Directors, see note G2 “Information regarding members of the Board of Directors and Group management” and note G3 “Share-based compensation.”

Disclosure of information about defined benefit plans [abstract]
G1 Post-employment benefits	Section G – Employee related 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 main change in 2021 was driven by higher than expected return on investments of SEK 3.5 billion. Financial assumption changes resulted in net actuarial gains on defined benefit obligations of SEK 0.3 billion although this was largely offset by experience losses in the year. 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 51% (48%) 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 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 non-guaranteed), 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 6.1 billion to PRI Pensionsgaranti. US plans The Company operates both defined contribution and defined benefit pension plans in the US, which are a combination of final salary pension plans and contribution-based arrangements. The final salary pension plans provide benefits to members in the form of a guaranteed level of pension payable for life. The level of benefits provided depends on members’ length of service and their salary in the final years leading up to retirement. Retirees generally do not receive inflationary increases once in payment. The other type of plan is a contribution-based pension plan, which provides a benefit determined using a “cash balance” approach. The balance is credited monthly with interest credits and contribution credits, based on a combination of current year salary and length of service. The majority of benefit payments are from trustee-administered funds; however, there are also a number of unfunded plans where the Company meets the benefit payment obligation as it falls due. In the US, the Company’s policy is at least to meet or exceed the funding requirements of federal regulations. The funded level in the US Pension Plan is above the point at which minimum funding would be required for fiscal year 2021. 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 and Trustees’ aim is to reduce the plans’ exposure to the key risks over time.

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, 2021, the discount rate applied in Sweden was 0.6% (0.5%). If the discount rate had been based on Swedish covered mortgage bonds, the discount rate as of December 31, 2021 would have been 2.1% (1.5%). If the discount rate based on Swedish covered mortgage bonds had been applied for the pension liability calculation, the DBO at December 31, 2021 would have been approximately SEK 18.8 (11.8) billion lower. US and UK The defined Higher corporate bond discount rates were used to value pensions liabilities in the US and UK plans at year end hence lowering the liabilities, although this was partially offset by higher inflation rate in the UK.

Disclosure of terms and conditions of share-based payment arrangement [abstract]
G3 Share-based compensation	Share-based compensation Accounting treatment of Long-Term Variable Compensation Programs In note A1” Significant accounting policies”, the overall accounting policies for share-based payments within the Company are disclosed. In summary: – 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 of provisions is recognized in the income statement in the period of final payout. Long-Term Variable Compensation All long-term variable compensation programs have been designed to form a part of a well-balanced total remuneration package and in general to span over a minimum of three years (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. Following discontinuation of the previous long-term variable compensation programs at the end of 2016, the shareholders approved the new Long-Term Variable Compensation Program (LTV) for the Executive Team (ET). The Company also introduced the new Executive Performance Plan (EPP) for senior managers and the Key Contributor Plan (KC Plan) for key employees as integral parts of its remuneration strategy starting from 2017. All new programs are share-based payment programs as defined by IFRS 2 “Share-based Payment,” either share- or cash-settled.

Share-Settled Programs Long-Term Variable Compensation Program for the Executive Team The Long-Term Variable Compensation Program for the ET as approved by the shareholders, is designed to provide long-term incentives for members of the ET and 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 and achieved vesting levels for the ones which the performance period have lapsed. It is generally required that the participant retains his or her employment over a period of three years from the date of grant of awards 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. 2021 Long-Term Variable Compensation Program for the Executive Team (LTV 2021) LTV 2021 was approved at the Annual General Meeting (AGM) of shareholders held in 2021 and includes all members of the ET, a total of 15 ET members in 2021, including the President and CEO. The participants were granted Performance Share Awards on May 3, 2021. 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 2020. Following evaluation of the previously introduced Long-term variable compensation programs, the Board of Directors decided to use the same performance criteria for LTV 2021 as the ones used for LTV 2020, LTV 2019 and LTV 2018 in order to secure continuity and consistency in supporting achievement of the Company’s 2022 targets. Hence again a one-year Group operating income (EBIT) target measured over the period January 1, 2021 to December 31, 2021 was included as a performance condition for LTV 2021 in addition to the standard three-year total shareholder return (TSR) performance conditions, which were also used for LTV 2020, LTV 2019 and LTV 2018. The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2021 to December 31, 2023 (the performance period). The performance criteria for LTV 2021 along with the details on how the performance criteria will be calculated and measured are explained in minutes from the AGM 2021 under Item 16.

Hence again a one-year Group operating income (EBIT) target measured over the period January 1, 2020 to December 31, 2020 was included as a performance condition for LTV 2020 in addition to the standard three-year total shareholder return (TSR) performance conditions, which were also used for LTV 2019, LTV 2018 and LTV 2017. The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2020 to December 31, 2022 (the performance period). The performance criteria for LTV 2020 along with the details on how the performance criteria will be calculated and measured are explained in minutes from the AGM 2020 under Item 17.

Hence again a one-year Group operating income (EBIT) target measured over the period January 1, 2019 to December 31, 2019 was included as a performance condition for LTV 2019 in addition to the standard three-year total shareholder return (TSR) performance conditions, which were also used for LTV 2018 and LTV 2017. The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2019 to December 31, 2021 (the performance period).

The maximum value of underlying shares in respect of the Performance Share Awards made to the ET members other than the President and CEO were increased from 22.5% in 2017 to between 30% and 70% of participants’ respective base salaries at the time of grant in 2018. The increases were approved at the AGM 2018 with the intention to increase the long-term focus and alignment with the long-term expectations of the shareholders. 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 first quarter of 2018. Following continuous evaluation of the Long-Term Variable Compensation Programs a one-year (EBIT) The performance criteria relating to TSR are absolute TSR development and relative TSR development for the Ericsson B share over the period January 1, 2018 to December 31, 2020 (the performance period). The performance criteria for LTV 2018 along with the details on how the performance criteria will be calculated and measured are explained in minutes from the AGM 2018 under Item 17.

The Performance Share Awards vested during 2021 and the participants received the equivalent number of shares free of charge with the official closure of LTV 2018. Cash-Settled Plans Executive Performance Plans (EPP) 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 2021 (EPP 2021) 159 senior managers were selected to participate in EPP 2021.

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 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.

Each of these two shareholders has issued 1,000,000 call options to Börje Ekholm on market terms (valuation conducted, using the Black & Scholes model, by an independent third party). Under the agreements, Börje Ekholm has purchased in total 2,000,000 call options, issued by the shareholders, for a purchase price of SEK 0.49 per call option. Each call option entitles the purchase of one Ericsson B share from the shareholders at a strike price of SEK 80 per share (to be recalculated to neutralize the effects of dividend payments during the option period) during one year after a seven-year seven-year In 2019 Investor AB, shareholder of Ericsson, made an offer to the Board Chairs of its listed core investment to purchase call options relating to shares in the respective core investment. Following this offer, Ronnie Leten, Chair of the Board of Directors, entered into such a call option agreement with Investor AB with respect to Class B share of Telefonaktiebolaget LM Ericsson. Under the agreement, Investor AB has issued 128,452 call options to Ronnie Leten on market terms (valuation conducted, using the Black & Scholes model, by an independent third party) and Ronnie Leten has purchased these call options for a purchase price of SEK 15.57 per call option. Each call option entitles the purchase of one Ericsson B share from Investor AB at a strike price of SEK 87.97 per share (to be recalculated to neutralize the effects of dividend payments during the option period) during one year after a four-year period starting February 5, 2019. Due to the fact that the call options were purchased on market terms as described above, no compensation expense has been recognized by the Company and will not be recognized during the remaining part of the period.

Tax loss carry-forwards Significant tax assets regarding tax loss carry-forwards are reported to the extent that realization of the related tax benefit through future taxable profits is probable also when considering the period during which these can be utilized, as described below. The majority of tax loss carry-forwards pertains to Sweden, United States, Mexico and Germany. These countries have long or indefinite periods of utilization. Of the total SEK 4,214 (4,417) million recognized deferred tax assets related to tax loss carry-forwards, SEK 3,512 (3,513) million relates to Sweden. Future income projections considering 5G roll-out, As of December 31, 2021, the recognized tax loss carry-forwards amounted to SEK 19,635 (21,442) million. The reduction is primarily attributable to utilization of the loss carry-forward against current year’s taxable income. The tax value of the tax loss carry-forward is reported as a tax asset based on the indefinite utilization period and the expectation that the group will realize a significant taxable income to offset these loss carry-forwards. The final years in which the recognized tax loss carry-forwards can be utilized are shown in the following table.

Events After The Reporting Period [Abstract]
Events after the reporting period	Events after the reporting period Legal proceedings Ericsson and Apple were not able to renew the now expired patent license agreement between the parties in a timely manner. On January 18, 2022 Ericsson filed three complaints with the U.S. International Trade Commission (ITC) alleging infringement of 12 patents by certain Apple products. In addition, Ericsson filed companion lawsuits in the Western District of Texas alleging infringement of the same 12 patents. Also, in January 2022 Ericsson filed complaints in several jurisdictions in Europe (Germany, Netherlands, Belgium) and South America (Brazil, Colombia) alleging that certain Apple products infringe Ericsson patents. On January 19, 2022 Apple filed a complaint against Ericsson in the ITC alleging infringement of three Apple patents by certain Ericsson products. Apple also filed a complaint in Germany at the District court of Düsseldorf alleging infringement of a German utility model and another complaint at the District court of Mannheim alleging infringement of an Apple patent by certain Ericsson products. The filing of lawsuits, complaints and other proceedings, when parties take legal action over a patent license agreement renewal, is standard and consequently additional lawsuits, complaints and other proceedings, may follow. Euro Medium Term Note program On February 8, 2022, the Company issued new EUR 750 million notes under the Euro Medium Term Note (EMTN) program, with maturity in February 2027. Vonage In November, 2021, Ericsson announced the entering into of an agreement to acquire Vonage Holdings Corp. for a total acquisition price of approximately USD 6.2 billion. Since then, Vonage shareholder approval has been obtained and all requisite foreign and U.S. regulatory requirements for closing have been satisfied, except for receipt of clearance from the Committee on Foreign Investment in the United States. If the agreement were to terminate under specified circumstances where we have failed to obtain such clearance, we may have to pay a USD 200 million termination fee to Vonage. Ericsson and Vonage continue to work toward closing this acquisition during the first half of 2022, on and subject to the terms of the merger agreement and subject to receiving regulatory approval. Update on Deferred Prosecution Agreement On December 6, 2019, Ericsson entered into a Deferred Prosecution Agreement (DPA) with the United States Department of Justice (DOJ). On March 1, 2022, the DOJ informed Ericsson that the disclosure made by the Company prior to the DPA about its internal investigation into conduct in Iraq in the period 2011 until 2019 was insufficient. Furthermore, it determined that the Company breached the DPA by failing to make subsequent disclosure related to the investigation post-DPA. The Company is in communication with the DOJ regarding the facts and circumstances of the breach determination and is committed to co-operating with the DOJ to r esolve the matter. At this stage it is premature to predict the outcome of this matter. DOJ has sole discretion under the DPA to determine whether a breach has occurred. Legal proceedings After the 2021 Swedish Annual Report Ericsson appoints Scott Dresser as Chief Legal Officer On March 16, 2022, Ericsson announced the appointment of Scott Dresser to the company’s Executive Team as Senior Vice President, Chief Legal Officer and Head of Group Function Legal Affairs & Compliance. Scott has joined Ericsson on 21 March 2022 and is based in the US. Scott Dresser replaces Xavier Dedullen, who resigned from this role as of the same date.

Summary Of Significant 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, 2021 have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the IASB, and as endorsed by the EU and RFR 1 “Additional rules for Group Accounting,” related interpretations issued by the Swedish Financial Reporting Board (Rådet för finansiell rapportering), and the Swedish Annual Accounts Act. For the financial reporting of 2021, the Company has applied IFRS as issued by the IASB (IFRS effective as per December 31, 2021). There is no difference between IFRS effective as per December 31, 2021, and IFRS as endorsed by the EU, nor is RFR 1 related interpretations issued by the Swedish Financial Reporting Board (Rådet för finansiell rapportering) or the Swedish Annual Accounts Act in conflict with IFRS, for all periods presented. The financial statements were approved by the Board of Directors on March 3, 2022. 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, 2021, can be found in the end of this note. The preparations for the adoption of new standards and interpretations not adopted in 2021 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 and loss (FVTPL), financial instruments classified as fair value through other comprehensive income (FVOCI) and plan assets related to defined benefit pension plans. Assets acquired under business combinations are fair valued at initial recognition. 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. Changes to the presentation in the financial statements Operating income has been renamed as EBIT (Earnings before financial items and income tax) and Operating margin as EBIT margin. The definitions of EBIT and EBIT margin remains unchanged. From 2021 current tax assets and current tax liabilities are presented as separate line items in the consolidated balance sheet. Previously current tax assets were included in other current receivables and current tax liabilities were included in other current liabilities. Prior year have been represented. The following changes were made to the presentation of the Consolidated statement of cash flows in 2021: - Interests and tax cash flows are presented as separate line items within the “Cash flow from operating activities.” Previously, interests and tax cash flows were subsumed within various lines in the sections “Adjustments to reconcile net income to cash” and “Changes in operating net assets,” and only disclosed in note H3 “Statement of cash flow.” Prior years have been represented and there is no impact on cash flows from operating activities. - Net movements in cash collaterals received and bank borrowings less than 3 months (used for short term liquidity purposes) are presented within “Other financing activities” since these balances fluctuate over a short duration, therefore it is neither practical nor useful to present their gross movements on the cash flow statement. Cash flow from financing activities in prior years have been restated accordingly, resulting in a reclassification between the lines “Proceeds from issuance of borrowings,” “Repayment of borrowings” and “Other financing activities,” with no net effect on total cash flow from financing activities. - Purchases and sales of interest-bearing securities are presented on a gross basis to improve the visibility of cash flows. Cash flow from investing activities in prior years have been restated accordingly, resulting in new lines for “Purchase of interest-bearing securities” and “Sale of interest-bearing securities”.
Basis of consolidation and composition of the Group	Basis of consolidation and composition of the Group The consolidated financial statements are prepared in accordance with the purchase method. Accordingly, consolidated stockholders’ equity includes equity in subsidiaries, joint ventures and associated companies earned only after their acquisition. Subsidiaries are all companies for which Telefonaktiebolaget LM Ericsson, directly or indirectly, is the parent. To be classified as a parent, Telefonaktiebolaget LM Ericsson, directly or indirectly, must control another company which requires that the Parent Company has power over that other company, is exposed to variable returns from its involvement and has the ability to use its power over that other company. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that such control ceases. Intra-group balances and any unrealized income and expense arising from intra-group transactions are fully eliminated in preparing the consolidated financial statements. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. The Company is composed of 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 transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at period-end Changes in the fair value of monetary securities denominated in foreign currency classified as fair value through other comprehensive income (FVOCI) are allocated between translation differences resulting from changes in the amortized cost of the security and other changes in the carrying amount of the security. Translation differences related to changes in the amortized cost are recognized in profit or loss, and other changes in the carrying amount are recognized in Other Comprehensive Income (OCI). Foreign 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.
Group companies	Group companies The results and financial position of all the group entities that have a functional currency different from the presentation currency are translated into the presentation currency as follows: Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet. Period income and expenses for each income statement are translated at period average exchange rates. All resulting net exchange differences are recognized as a separate component of Other comprehensive income (OCI). On consolidation, exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are accounted for in OCI. When a foreign operation is disposed of or sold, exchange differences that were recorded in OCI are recognized in the income statement as part of the gain or loss on sale. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and are translated at the closing rate. The Company is continuously monitoring the economies with high inflation, the risk of hyperinflation and potential impact on the Company. There is no significant impact due to any currency translation of a hyper-inflationary economy.
Revenue recognition	Revenue recognition IFRS 15, “Revenue from Contracts with Customers” is a principle-based model of recognizing revenue from customer contracts. It has a five-step model that requires revenue to be recognized when control over goods and services are transferred to the customer. The following paragraphs describes the types of contracts, when performance obligations are satisfied, and the timing of revenue recognition. They also describe the normal payment terms associated with such contracts and the resulting impact on the balance sheet over the duration of the contracts. The vast majority of Ericsson’s business is for the sale of standard products and services.
Standard products and services	Standard products and services Products and services are classified as standard solutions if they do not require significant installation and integration services to be delivered. Installation and integration services are generally completed within a short period of time, from the delivery of the related products. These products and services are viewed as separate distinct performance obligations. This type of customer contract is usually signed as a frame agreement and the customer issues individual purchase orders to commit to purchases of products and services over the duration of the agreement. Revenue for standard products is recognized when control over the equipment is transferred to the customer at a point in time. This assessment shall be viewed from a customer’s perspective considering indicators such as transfer of titles and risks, customer acceptance, physical possession, and billing rights. For hardware sales, transfer of control is usually deemed to occur when the equipment arrives at the customer site and for software sales, when the licenses are made available to the customer. Software licenses may be provided to the customer at a point in time, activated or ready to be activated by the customer at a later stage, therefore revenue is recognized when customer obtains control of the software. Contractual terms vary, therefore judgment will be applied when assessing the indicators of transfer of control for both hardware and software sales. Software licenses are also sold on a when-and-if Transaction prices under these contracts are usually fixed, and mostly billed upon delivery of the hardware or software, or completion of installation services. A proportion of the transaction price may be billed upon formal acceptance of the related installation services, which will result in a contract asset for the proportion of the transaction price that is not yet billed. Amounts billed are normally subject to payments terms within 60 days from invoice date. Customer finance agreements may be agreed separately with some customers where payment terms exceed 179 days. Revenue for recurring services such as customer support and managed services is recognized as the services are delivered, generally pro-rata
Customized solution	Customized solution Some products and services are sold together as part of a customized solution to the customer. This type of contract requires significant installation and integration services to be delivered within the solution, normally over a period of more than one year. These products and services are viewed together as a combined performance obligation. This type of contract is usually sold as a firm contract in which the scope of the solution and obligations of both parties are clearly defined for the duration of the contract. Customized solution does not have any alternative use to the Company as it cannot be sold to or used by other customers. Revenue for the combined performance obligation shall be recognized over time if progress of completion can be reliably measured and enforceable right to payment exists over the duration of the contract. The progress of completion is estimated by reference to the output delivered such as achievement of contract milestones and customer acceptance. This method determines revenue milestones over the duration of the contract, and it is considered appropriate as it reflects the nature of the customized solution and how integration service is delivered in these projects. If the criteria above are not met, then all revenue shall be recognized upon the completion of the customized solution, when final acceptance is provided by the customer. Costs incurred in delivering customized solutions are recognized as costs of sales when the related revenue milestone is recognized in the Income statement. Costs incurred relating to future revenue milestones are recognized as Inventories and assessed for recoverability on a regular basis. Transaction price under these contracts is usually a fixed fee, split into a number of progress payments or billing milestones as defined in the contract. In most cases, revenue recognized is limited to the progress payments or unconditional billing milestones over the duration of the contract, therefore no contract asset or contract liability arises on these contracts. In some contracts, revenue may be recognized in advance of billing milestones if enforceable payment rights exist at all times over the contract duration. This will result in an unbilled receivable balance until billing milestones are reached. Amounts billed are normally subject to payments terms within 60 days from invoice date. Customer finance agreements may be agreed separately with some customers where payment terms exceed 179 days. Contract for customized solution applies to the Business Support Systems (BSS) business within the segment Digital Services.
Intellectual Property Rights (IPR)	Note A1, cont’d. Customized solution Some products and services are sold together as part of a customized solution to the customer. This type of contract requires significant installation and integration services to be delivered within the solution, normally over a period of more than one year. These products and services are viewed together as a combined performance obligation. This type of contract is usually sold as a firm contract in which the scope of the solution and obligations of both parties are clearly defined for the duration of the contract. Customized solution does not have any alternative use to the Company as it cannot be sold to or used by other customers. Revenue for the combined performance obligation shall be recognized over time if progress of completion can be reliably measured and enforceable right to payment exists over the duration of the contract. The progress of completion is estimated by reference to the output delivered such as achievement of contract milestones and customer acceptance. This method determines revenue milestones over the duration of the contract, and it is considered appropriate as it reflects the nature of the customized solution and how integration service is delivered in these projects. If the criteria above are not met, then all revenue shall be recognized upon the completion of the customized solution, when final acceptance is provided by the customer. Costs incurred in delivering customized solutions are recognized as costs of sales when the related revenue milestone is recognized in the Income statement. Costs incurred relating to future revenue milestones are recognized as Inventories and assessed for recoverability on a regular basis. Transaction price under these contracts is usually a fixed fee, split into a number of progress payments or billing milestones as defined in the contract. In most cases, revenue recognized is limited to the progress payments or unconditional billing milestones over the duration of the contract, therefore no contract asset or contract liability arises on these contracts. In some contracts, revenue may be recognized in advance of billing milestones if enforceable payment rights exist at all times over the contract duration. This will result in an unbilled receivable balance until billing milestones are reached. Amounts billed are normally subject to payments terms within 60 days from invoice date. Customer finance agreements may be agreed separately with some customers where payment terms exceed 179 days. Contract for customized solution applies to the Business Support Systems (BSS) business within the segment Digital Services. Intellectual Property Rights (IPR) This type of contract relates to the patent and licensing business. The Company has assessed that the nature of its IPR contracts is such that they provide customers a license with the right to access the Company intellectual properties over time, therefore revenue shall be recognized over the duration of the contract. Royalty revenue based on sales or usage is recognized when the sales and usage occur. The transaction price on these contracts is usually structured as a royalty fee based on sales or usage over the period, measured on a quarterly basis. This results in a receivable balance if the billing is performed the following quarter after measurement. Some contracts include lump sum amounts, payable either up front at commencement or on an annual basis. This results in a contract liability balance if payment is in advance of revenue, as revenue is recognized over time. Amounts billed are normally subject to payments terms within 60 days from invoice date. As described in note B1 “Segment Information”, revenue from IPR licensing contracts are allocated to the segments Networks and Digital Services.
Customer contract related balances	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. Customer finance credits arise from credit terms exceeding 179 days in the customer contract or a separate financing agreement signed with the customer. Customer finance is a class of financial assets that is managed separately from receivables. See note F1 “Financial risk management,” for further information on credit risk management of trade receivables and customer finance credits. In accordance with IFRS 15, where significant financing is provided to the customer, revenue is adjusted to reflect the impact of the financing transaction. These transactions could arise from the customer finance credits above if the contracted interest rate is below the market rate or through implied financing transactions due to payment terms of more than one year from the date of transfer of control. The Company has elected to use the practical expedient not to adjust revenue for transactions with payment terms, measured from the date of transfer of control, of one year or less. Contract asset is unbilled sales amount relating to performance obligation that has been satisfied under customer contract but is conditional on terms other than only the passage of time before payment of the consideration is due. Contract liability relates to amounts that are paid by or due from customers for which performance obligations are unsatisfied or partially satisfied. Advances from customers are also included in the contract liability balance.
Segment reporting	Segment reporting An operating segment is a component of a company whose operating results are regularly reviewed by the Company’s chief operating decision maker (CODM), to make decisions about resources to be allocated to the segment and assess its performance. The President and the CEO is defined as the CODM function in the Company. The segment presentation, as per each segment, is based on the Company’s accounting policies as disclosed in this note. The Company generally has one subsidiary for each jurisdiction and within each of the subsidiaries, each financial statement item is defined and allocated to each of the different segments. The Company’s segment disclosure about geographical areas is based on the country in which transfer of risks and rewards occur. For further information, see note B1 “Segment information.”
Inventories	Inventories Inventories are measured at the lower of cost or net realizable value on a first-in, first-out Risks of obsolescence have been measured by estimating market value based on future customer demand and changes in technology and customer acceptance of new products. A significant part of Inventories is Contract work in progress (CWIP). Recognition and derecognition of CWIP relates to the Company’s revenue recognition principles meaning that costs incurred under a customer contract are initially recognized as CWIP (see Revenue recognition policy). When the related revenue is recognized, CWIP is derecognized and is instead recognized as Cost of sales. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Trade payables	Trade payables See accounting policies under the subheading for Financial instruments and risk management.
Goodwill	Goodwill As from the acquisition date, goodwill acquired in a business combination is allocated to each cash-generating unit (CGU) of the Company expected to benefit from the synergies of the combination. An annual impairment test for the CGUs to which goodwill has been allocated is performed in the fourth quarter, or when there is an indication of impairment. An impairment loss is recognized if the carrying amount of an asset or its cash-generating unit exceeds its recoverable amount. The recoverable amount is the higher of the value in use and the fair value less costs of disposal. In assessing value in use, the estimated future cash flows after tax are discounted to their present value using an after-tax after-tax 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 intangible assets acquired through business combinations, such as patents, customer relations, trademarks and software, as well as capitalized development expenses and separately acquired intangible assets, mainly consisting of software. At initial recognition, acquired intangible assets relating to business combinations are stated at fair value and capitalized development expenses and software are stated at cost. Subsequent to initial recognition, these intangible assets are stated at the initially recognized amounts less accumulated amortization and any impairment. Amortization and any impairment losses are included in Research and development expenses, which mainly consists of capitalized development expenses and technology; in Selling and administrative expenses, which mainly consists of expenses relating to customer relations and brands; and in Cost of sales. Costs incurred for the development of products to be sold, leased, or otherwise marketed or intended for internal use are capitalized as from when technological and economic feasibility has been established until the product is available for sale or use. Research and development expenses directly related to orders from customers are accounted for as a part of Cost of sales. Other research and development expenses are charged to the income statement as incurred. Amortization of acquired intangible assets, such as patents, customer relations, trademarks, and software, is made according to the straight-line method over their estimated useful lives, not exceeding ten years. Amortization of capitalized development expenses is made according to the straight-line method over their useful lives normally three years. The Company has not recognized any intangible assets with indefinite useful life other than goodwill. Impairment tests are performed whenever there is an indication of impairment. Tests are performed in the same way as for goodwill, see above. However, intangible assets not yet available for use are tested annually. Corporate assets have been allocated to cash-generating units in relation to each unit’s proportion of total net sales. The amount related to corporate assets is not significant. Impairment losses recognized in prior periods are assessed at each reporting date for any indications that the loss has decreased or longer exists. In note A , “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, in general, 25–50 years for real estate and 3–10 years for machinery and equipment. Depreciation and any impairment charges are included in Cost of sales, Research and development or Selling and administrative expenses. The Company recognizes in the carrying amount of an item of property, plant, and equipment the cost of replacing a component and derecognizes the residual value of the replaced component. Impairment testing as well as recognition or reversal of impairment of property, plant and equipment is performed in the same manner as for intangible assets other than goodwill, see description under “Intangible assets other than goodwill” above. Gains and losses on disposals are determined by comparing the proceeds less cost to sell with the carrying amount and are recognized within Other operating income and expenses in the income statement.
Leases	Leases The main types of assets leased by the Company are, in the order of materiality, real estate, 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 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. After the commencement date, the amount of lease liabilities is measured on an amortized cost basis using the effective interest method where the lease liabilities increase related to the accrued interest and decrease due to lease payments made. In addition, the lease liability is remeasured if there is a modification, a change in the lease term or a change in the future lease payments resulting from a change in an index or rate used to determine such lease payments. At commencement date the right-of-use After commencement date the right-of-use right-of-use right-of-use 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. The interest expense on lease liabilities in the income statement is presented as a component of finance costs separate from the depreciation charges for right-of-use low-value Leases when the Company is the lessor Lease contracts with the Company as lessor are classified as finance leases when substantially all of risks and rewards are transferred to the lessee, and otherwise as operating leases. Under a finance lease, a receivable is recognized at an amount equal to the net investment in the lease and revenue is recognized in accordance with the revenue recognition principles. Under operating leases revenue as well as depreciation is recognized on a straight-line basis over the lease term. When the Company acts as a lessor it is mainly in relation to real estate sublease, financing and operating.
Provisions	Provisions Provisions are made when there are legal or constructive obligations as a result of past events and when it is probable that an outflow of resources will be required to settle the obligations and the amounts can be reliably estimated. When the effect of the time value of money is material, 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 and other obligations, 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. Provision for restructuring is recorded when the Company can reliably estimate the liabilities relating to the obligation. The estimate is based on the Company’s expected expenditure to settle the obligation and is adjusted when changes to the expenditure is known. 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. These contract loss estimates may include penalties under a loss contract. Supplier-related provisions consist of guarantees or claims by suppliers. A provision equal to the best estimate of the expected expenditure to settle the obligation is raised when the Company can reliably estimate the obligation and it is probable that there will be an outflow of resources required to settle the obligation. 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 litigations. 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. To the extent that the Company makes the judgment that an identified potential infringement will more likely than not result in an outflow of resources, the Company records a provision based on the Company’s best estimate of the expenditure required to settle with the counterpart. In the ordinary course of business, the Company is subject to proceedings, lawsuits, and other unresolved claims, including proceedings under laws and government regulations and other matters. These matters are often resolved over a long period of time. The Company regularly assesses the likelihood of any adverse judgments in or outcomes of these matters, as well as potential ranges of possible losses. Provisions are recognized when it is probable that an obligation has arisen, and the amount can be reasonably estimated based on a detailed analysis of each individual issue.
Contingent liabilities	Contingent liabilities Certain present obligations are not recognized as provisions as it is not probable that an economic outflow will be required to settle the obligations or the amount of the obligation cannot be measured with sufficient reliability, or there is a possible obligation arising from a past event, which will be confirmed by the occurrence or non-occurrence of a future uncertain event, not within the control of the Company. Such obligations are reported as contingent liabilities. For further detailed information, see note D2 “Contingent liabilities.” In note A2 “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Business combinations	Business combinations At the acquisition of a business, the cost of the acquisition, being the purchase price, is measured as the fair value of the assets given, and liabilities incurred or assumed at the date of exchange, including any cost related to contingent consideration. Transaction costs attributable to the acquisition are expensed as incurred. The acquisition cost is allocated to acquired assets, liabilities, and contingent liabilities based upon appraisals made, including assets and liabilities that were not recognized on the acquired entity’s balance sheet, for example, intangible assets such as customer relations, brands, patents, and financial liabilities. Goodwill arises when the purchase price exceeds the fair value of recognizable acquired net assets. In acquisitions with non-controlling In case there is a put option for a non-controlling
Non-controlling interests	Non-controlling The Company treats transactions with non-controlling non-controlling non-controlling At acquisition, there is a choice on an acquisition-by-acquisition non-controlling non-controlling
Joint ventures and associated companies	Joint ventures and associated companies When the Company ceases to have control, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest in an associate or financial asset. In addition, any amounts previously recognized in Other comprehensive income in respect of that entity are accounted for as if the Company had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in Other comprehensive income are reclassified to profit or loss. Joint ventures and associated companies are accounted for in accordance with the equity method. Under the equity method, the investment in the joint venture or associate is initially recognized at cost and the carrying amount is increased or decreased to recognize the investor’s share of the profit or loss of the investee after the date of acquisition. If the Company’s interest in an associated company is nil, the Company shall not, as prescribed in IFRS, recognize its part of any future losses. Provisions related to obligations for such an interest shall, however, be recognized in relation to such an interest. Investments in associated companies is, when the Company has significant influence and the power to participate in the financial and operating policy decisions of the associated company but is not in control or joint control over those policies. Normally, this is the case in voting stock interest, including effective potential voting rights, which stand at least at 20% but not more than 50%. The Company’s share of income before taxes is reported in item “Share in earnings of joint ventures and associated companies,” included in EBIT. This reflects the fact that these interests are held for operating rather than investing or financial purposes. Ericsson’s share of income taxes related to associated companies is reported under the line item “Income tax,” in the income statement. Unrealized gains on transactions between the Company and its joint ventures and associated companies are eliminated to the extent of the Company’s interest in these entities. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Shares in earnings of joint ventures and associated companies are included in consolidated equity since they are undistributed. They are reported in retained earnings in the balance sheet. Impairment testing, as well as recognition or reversal of impairment of investments in each joint venture and associated company, is performed in the same manner as for intangible assets other than goodwill. The entire carrying value of each investment, including goodwill, is tested as a single asset. See also description under “Intangible assets other than goodwill” below. If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in Other comprehensive income are reclassified to profit or loss where appropriate. In note A2, “Critical Accounting Estimates and Judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Financial assets	Financial assets Financial assets are recognized when the Company becomes a party to the contractual provisions of the instrument. Regular purchases and sales of financial 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. Separate assets or liabilities are recognized if any rights and obligations are created or retained in the transfer. The Company classifies its financial assets in the following categories: at amortized cost, at fair value through other comprehensive income (FVOCI), and at fair value through profit or loss (FVTPL). The classification depends on the cash flow characteristics of the asset and the business model in which it is held. Financial assets are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. The fair values of quoted financial investments and derivatives are based on quoted market prices or rates. If official rates or market prices are not available, fair values are calculated by discounting the expected future cash flows at prevailing interest rates. Valuations of foreign exchange options and Interest Rate Guarantees (IRG) are made by using the Black-Scholes formula. Inputs to the valuations are market prices for implied volatility, foreign exchange and interest rates.
Financial assets at amortized cost	Financial assets at amortized cost Financial assets are classified as amortized cost if the contractual terms give rise to payments that are solely payments of principal and interest on the principal amount outstanding and the financial asset is held in a business model whose objective is to hold financial assets in order to collect contractual cash flows. These assets are subsequently measured at amortized cost using the effective interest method, minus impairment allowances. Interest income and gains and losses from financial assets at amortized cost are recognized in financial income.
Financial assets at fair value through other comprehensive income	Financial assets at fair value through other comprehensive income (FVOCI) Assets are classified as FVOCI if the contractual terms give rise to payments that are solely payments of principal and interest on the principal amount outstanding and the financial asset is held in a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets. These assets are subsequently measured at fair value with changes in fair value recognized in other comprehensive income (OCI), except for effective interest, impairment gains and losses and foreign exchange gains and losses which are recognized in the income statement. Upon derecognition, the cumulative gain or loss in OCI is reclassified to the income statement.
Financial assets at fair value through profit or loss	Financial assets at fair value through profit or loss (FVTPL) All financial assets that are not classified as either amortized cost or FVOCI are classified as FVTPL. 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 set-off, 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). ECLs are the differences between all contractual cash flows that are due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at the original effective interest rate. 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 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. Default is deemed if the asset is more than 90 days past due, after which lifetime ECL is 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.
Borrowings	Borrowings Borrowings issued by the Parent Company are designated FVTPL because they are managed on a fair value basis. Changes in fair value are recognized in financial expense, except for changes in fair value due to changes in credit risk which are recognized in other comprehensive income. Borrowings not issued by the Parent Company are classified as amortized cost liabilities. They are initially recognized at fair value, net of transaction costs incurred. These borrowings are subsequently measured at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method. Borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date.
Cash flow hedge accounting	Cash flow hedge accounting The Company identified certain customer contracts where a fluctuation in the USD/SEK foreign exchange (FX) rate would significantly impact net sales and EBIT recorded from the contracts. These contracts are multi-year contracts denominated in USD with highly probable payments at fixed points in time. 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 ies 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
Post-employment benefits	Post-employment benefits Pensions and other post-employment benefits are classified as either defined contribution plans or defined benefit plans. Under a defined contribution plan, the Company’s only obligation is to pay a fixed amount to a separate entity (a pension trust fund) with no obligation to pay further contributions if the fund does not hold sufficient assets to pay all employee benefits. The related actuarial and investment risks fall on the employee. The expenditures for defined contribution plans are recognized as expenses during the period when the employee provides service. Under a defined benefit plan, it is the Company’s obligation to provide agreed benefits to current and former employees. The related actuarial and investment risks fall on the Company. The present value of the defined benefit obligations for current and former employees is calculated using the Projected Unit Credit Method. The discount rate for each country is determined by reference to market yields on high-quality corporate bonds that have maturity dates approximating the terms of the Company’s obligations. In countries where there is no deep market in such bonds, the market yields on government bonds are used. The calculations are based upon actuarial assumptions that are updated annually. Actuarial assumptions are the Company’s best estimate of the variables that determine the cost of providing the benefits. When using actuarial assumptions, it is possible that the actual results will differ from the estimated results or that the actuarial assumptions will change from one period to another. These differences are reported as actuarial gains and losses. They are, for example, caused by unexpectedly high or low rates of employee turnover, changed life expectancy, salary changes and changes in the discount rate. Actuarial gains and losses and gains and losses from remeasurement of plan assets are recognized in OCI in the period in which they occur. The Company’s net liability for each defined benefit plan consists of the present value of pension commitments less the fair value of plan assets and is recognized net on the balance sheet. When the result is a net benefit to the Company, the recognized asset is limited to the present value of any future refunds from the plan or reductions in future contributions to the plan, referred to as ‘asset ceiling’. Interest cost on the defined benefit obligation and interest income on plan assets is calculated as a net interest amount by applying the discount rate to the net defined benefit liability. Current service cost relating to employee service is recognised in the profit and loss in the period. Past service cost relating to plan amendments or curtailment is recognized immediately in the period it occurs. Swedish special payroll tax is accounted for as a part of the pension cost and the pension liability respectively. Payroll taxes related to actuarial gains and losses are included in determining actuarial gains and losses, reported under OCI. In note A2, “Critical accounting estimates and judgments” further disclosure is presented in relation to key sources of estimation uncertainty.
Share-based compensation to employees and the Board of Directors	Share-based compensation to employees and the Board of Directors Share-based compensation is related to remuneration to employees, including key management personnel and the Board of Directors and could be settled either in shares or cash. Under IFRS, a company shall recognize compensation costs for share-based compensation programs based on a measure of the value to the company of services received under the plans. For share-settled plans, a corresponding increase in equity shall be recognized. As from 2017 the granted share-based programs are cash-settled, except for programs for the Executive Team. Those programs are share-settled. Share-settled plans Compensation costs are recognized during the vesting period, based on the fair value of the Ericsson share at the grant date, as well as considering performance – and market conditions. Examples of performance conditions could be revenue and profit targets while market conditions relate to the development of the Parent Company’s share price in relation to a group of reference shares. All plans have service conditions and some of them have performance or market conditions. For share-settled plans, a corresponding increase in equity shall be recognized. The reason for this IFRS accounting principle is that compensation cost for a share-settled program is a cost with no direct cash flow impact. 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. For further detailed information, see note G3 “Share-based compensation.” Compensation to the Board of Directors Since 2008, the annual general shareholders meeting of the Parent Company has each year resolved that the Board members shall be able to choose to receive part of the Board remuneration in the form of synthetic shares. The program gives non-employee pro-rata
Income taxes	Income taxes Income taxes in the consolidated financial statements include both current and deferred taxes. Income taxes are reported in the income statement unless the underlying item is reported directly in equity or OCI. For those items, the related income tax is also reported directly in equity or OCI. A current tax liability or asset is recognized for the estimated taxes payable or refundable for the current year or prior years. Current income tax is measured at the tax rate that is expected to be applied based on the tax laws that have been 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 and for tax loss carry-forwards. A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the deductible temporary differences and tax loss carry-forwards can be utilized. In the recognition of income taxes, the Company offsets current tax receivables against current tax liabilities and deferred tax assets against deferred tax liabilities in the balance sheet, when the Company has a legal right to offset these items and the intention to do so. Deferred tax is not recognized for the following temporary differences: goodwill not deductible for tax purposes, for the initial recognition of assets or liabilities that affect neither accounting nor taxable profit and for differences related to investments in subsidiaries when it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is measured at the tax rate that is expected to be applied to the temporary differences when they reverse, based on the tax laws that have been enacted or substantively enacted by the reporting date. An adjustment of deferred tax asset/liability balances due to a change in the tax rate is recognized in the income statement, unless it relates to a temporary difference earlier recognized directly in equity or OCI, in which case the adjustment is also recognized in equity or OCI. As prescribed in IFRIC 23, uncertainty over income tax treatment is considered if and when recognizing and measuring income tax items in the financial statements. As a result of applying IFRS 16 “Leases,” the Company has not reported deferred tax on initial recognition. The exemption in IAS 12 is applied i.e. no deferred tax is reported for the initial recognition of a right-of-use The measurement of deferred tax assets involves judgment regarding the deductibility of costs not yet subject to taxation and estimates regarding sufficient future taxable income to enable utilization of unused tax losses in different tax jurisdictions. All deferred tax assets are subject to annual review of probable utilization. In note A2, “Critical accounting estimates and judgments,” further disclosure is presented in relation to (i) key sources of estimation uncertainty and (ii) the decision made in relation to accounting policies applied.
Earnings per share	Earnings per share Basic earnings per share are calculated by dividing net income attributable to owners of the Parent Company by the weighted average number of shares outstanding (total number of shares less treasury shares) during the year. Diluted earnings per share are calculated by dividing net income attributable to owners of the Parent Company, when appropriately adjusted by the sum of the weighted average number of ordinary shares outstanding and dilutive potential ordinary shares. Potential ordinary shares are treated as dilutive when, and only when, their conversion to ordinary shares would decrease earnings per share. Rights to matching shares are considered dilutive when the actual fulfilment of any performance conditions as of the reporting date would give a right to ordinary shares.
Statement of cash flows	Statement of cash flows The statement of cash flows is prepared in accordance with the indirect method. Cash flows in foreign subsidiaries are translated at the average exchange rate during the period. Payments for subsidiaries acquired or divested are reported as cash flow from investing activities, net of cash and cash equivalents acquired or disposed of respectively. Cash and cash equivalents consist of cash, bank, and interest-bearing securities that are highly liquid monetary financial instruments with a remaining maturity of three months or less at the date of acquisition.
