Accounting Policies [Abstract]

Accounting Policies

ACCOUNTING POLICIES

The accounting policies of the Company conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”). All balances and values in the current and prior periods are in millions of U.S. dollars, except share and per-share amounts. Under Article 35 of the Company’s Articles of Association, the financial year extends from January 1 to December 31, which is the period-end of each fiscal year.

2.1 Basis of presentation and consolidation

The Company's consolidated financial statements include the assets, liabilities, results of operations and cash flows of its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company assesses each investment in equity securities to determine whether the investee is a Variable Interest Entity (“VIE”). The Company consolidates the VIEs for which the Company is determined to be the primary beneficiary. The primary beneficiary of a VIE is the party that: (i) has the power to direct the most significant activities of the VIE and (ii) is obligated to absorb losses or has the rights to receive returns that would be considered significant to the VIE.

When the Company owns some, but not all, of the voting stock of a consolidated entity, the shares held by third parties represent a noncontrolling interest. The consolidated financial statements are prepared based on the total amount of assets and liabilities and income and expenses of the consolidated subsidiaries. However, the portion of these items that does not belong to the Company’s shareholders is reported in the line “Noncontrolling interest” of the consolidated financial statements.

2.2 Use of estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions. The primary areas that require significant estimates and judgments by management include, but are not limited to:

•sales allowances for discounts, price protection, product returns and other rebates,

•inventory obsolescence reserves and normal manufacturing capacity thresholds to determine costs capitalized in inventory,

•recognition and measurement of loss contingencies,

•valuation at fair value of assets acquired and liabilities assumed on business acquisitions, and measurement of any contingent consideration,

•annual and trigger-based impairment review of goodwill and intangible assets, as well as the assessment of events which could trigger impairment testing on tangible assets,

•assessment of the Company’s long-lived assets economic useful lives,

•assumptions used in measuring expected credit losses and impairment charges on financial assets,

•assumptions used in assessing the number of awards expected to vest on stock-based compensation plans,

•assumptions used in calculating net defined pension benefit obligations and other long-term employee benefits,

•determination of the amount of tax expected to be paid and tax benefit expected to be received, including deferred income tax assets, valuation allowance and provisions for uncertain tax positions and claims.

The Company bases the estimates and assumptions on historical experience and on various other factors such as market trends, market information used by market participants and the latest available business plans that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. While the Company regularly evaluates its estimates and assumptions, the actual results experienced by the Company could differ materially and adversely from those estimates.

2.3 Foreign currency

The U.S. dollar is the reporting currency of the Company. The U.S. dollar is the currency of the primary economic environment in which the Company operates since the worldwide semiconductor industry uses the U.S. dollar as a currency of reference for actual pricing in the market. Furthermore, the majority of the Company’s transactions are denominated in U.S. dollars, and revenues from external sales in U.S. dollars largely exceed revenues in any other currency. However, certain significant costs are incurred in the countries of the Eurozone and other non-U.S. dollar currency areas.

The functional currency of each subsidiary of the Company is either the local currency or the U.S. dollar, depending on the basis of the economic environment in which each subsidiary operates. Foreign currency transactions, including operations in local currency when the U.S. dollar is the functional currency, are measured into the functional currency using the prevailing exchange rate. Foreign exchange gains and losses resulting from the re-measurement at reporting date of monetary assets and liabilities denominated in currencies other than the functional currency are recognized in the line “Other income and expenses, net” of the consolidated statements of income.

For consolidation purposes, the results and financial position of the subsidiaries whose functional currency is different from the U.S. dollar are translated into the reporting currency as follows:

(a)assets and liabilities for each consolidated balance sheet presented are translated into U.S. dollars using exchange rates at the balance sheet dates;

(b)income and expenses for each consolidated statement of income presented are translated into U.S dollars using the monthly exchange rates;

(c)the resulting exchange differences are reported as Currency Translation Adjustments (“CTA”), a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income.

2.4 Cash and cash equivalents

Cash and cash equivalents include cash on hand, deposits held at call with external financial institutions and other short-term highly liquid investments with effective maturities of three months or less. They are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates.

Short-term deposits representing cash equivalents with maturity beyond three months and below one year are reported as current assets in the line “Short-term deposits” of the consolidated balance sheets.

2.5 Trade accounts receivable

Trade accounts receivable are amounts due from customers for goods sold and services rendered to third parties in the ordinary course of business. The Company uses a lifetime expected losses allowance for all trade receivables. The allowance includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of the Company’s customers to settle the receivables. Adjustments to the expected credit losses allowance are reported on the line “Selling, general and administrative expenses” in the consolidated statements of income and write-offs, if any, are recorded against the expected credit losses allowance.

In the event of transfers of receivables such as factoring, the Company derecognizes the receivables only to the extent that the Company has surrendered control over the receivables in exchange for a consideration other than beneficial interest in the transferred receivables.

2.6 Inventories

Inventories are stated at the lower of cost and net realizable value. Actual cost is based on an adjusted standard cost, which approximates cost on a first-in, first-out basis for all categories of inventory (raw materials, work-in-process, finished products). Actual cost is therefore dependent on the Company’s manufacturing performance and is based on the normal utilization of its production capacity. In case of underutilization of manufacturing facilities, the costs associated with unused capacity are not included in the valuation of inventories but charged directly to cost of sales. Net realizable value is based upon the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Inventory reserve is estimated for excess uncommitted inventory based on historical sales data, order backlog and production plans. The Company performs, on a continuous basis, write-offs of inventories, which have the characteristics of slow-moving, old production dates and technical obsolescence. The Company evaluates its inventory to identify obsolete or slow-selling items, as well as inventory that is not of saleable quality and records a specific reserve if the Company estimates the inventory will eventually be written off.

2.7 Income taxes

Income tax for the period comprises current and deferred income tax. Income tax expense represents the income tax expected to be paid related to the current year taxable profit in each tax jurisdiction. Deferred income tax is recognized for all temporary differences arising between the tax bases of assets and liabilities and their carrying amount in the consolidated financial statements. Deferred tax assets are also recognized on temporary differences arising from tax losses carried forward and tax credits. Deferred tax liabilities are not recognized on the initial recognition of goodwill as a result of a business combination. Deferred income tax is determined using tax rates and laws that are enacted at the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled. The effect on deferred tax assets and liabilities from changes in tax laws and tax rates is recognized on the line “Income tax expense” in the consolidated statements of income in the period in which the law is enacted. Deferred income tax assets are recognized in full but the Company assesses whether future taxable profit will be available against which temporary differences can be utilized. A valuation allowance is provided for deferred tax assets when management considers it is more likely than not that they will not be realized.

The Company recognizes a deferred tax liability on undistributed earnings of subsidiaries when there is a presumption that taxable earnings will be remitted to the parent. A deferred tax asset is recognized on

compensation for the grant of stock awards to the extent that such charge constitutes a temporary difference in the subsidiaries’ local tax jurisdictions. Changes in the stock price do not result in any adjustments to the deferred tax asset prior to vesting.

At each reporting date, the Company assesses all significant income tax positions in all tax jurisdictions to determine any uncertain tax positions. The Company uses a two-step process for the evaluation of uncertain tax positions. The first step consists in assessing whether the tax benefit must be recognized. The second step consists in measuring the amount of tax benefit to be recognized on each uncertain tax position. In step 1 (recognition), the Company assesses whether a tax position, based solely on its technical merits, is more likely than not to be sustained upon examination. Only tax positions with a sustainability threshold higher than 50% are recognized. In Step 2 (measurement), the Company determines the amount of recognizable tax benefit. The measurement methodology is based on a “cumulative probability” approach, resulting in the recognition of the largest amount that is greater than 50% likely of being realized upon settlement with the taxing authority. The Company accrues for interest and penalties on uncertain tax liabilities reported on the consolidated balance sheets. Interests and penalties are classified as components of income tax expense in the consolidated statements of income.

2.8 Business combinations and goodwill

The acquisition method of accounting is applied to all business combinations. The identifiable assets acquired, liabilities assumed, and equity instruments issued are measured at acquisition date fair value. Any contingent consideration is recorded at acquisition date fair value and remeasured at each reporting date. Acquisition-related transaction costs and restructuring costs related to the acquired business are expensed as incurred. Acquired in-process research and development (“IPR&D”) is capitalized and recorded as an intangible asset at acquisition date, subject to impairment testing until the research or development is completed. The excess of the consideration transferred over the acquisition-date fair value of the identifiable assets acquired and liabilities assumed, net of related deferred tax impacts, is recorded as goodwill. In case of a bargain purchase, the Company reassesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed, the noncontrolling interest in the acquiree, if any, the Company’s previously held equity interest in the acquiree, if any, and the consideration transferred. If after this review, a bargain purchase is still indicated, it is recognized in earnings attributable to parent company stockholders. The purchase of additional interests in a partially owned subsidiary is treated as an equity transaction as well as all transactions concerning the sale of subsidiary stock or the issuance of stock by the partially owned subsidiary, assuming there is no change in control of the subsidiary. In the case of a sale of subsidiary shares, whereby the Company no longer maintains control of the subsidiary, the Company recognizes a gain or loss in earnings.

Goodwill is carried at cost less accumulated impairment losses, if any. Goodwill is not amortized but is tested for impairment at least annually, and more frequently whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. Goodwill subject to potential impairment is tested at the reporting unit level. The impairment test determines whether the fair value of each reporting unit under which goodwill is allocated is lower than the total carrying amount of relevant net assets allocated to such reporting unit, including its allocated goodwill. The Company records an impairment loss on goodwill when a reporting unit’s carrying value exceeds its fair value. Significant management judgments and estimates are used in forecasting the future discounted cash flows associated with the reporting unit, including: the applicable industry’s sales volume forecast and selling price evolution, the reporting unit’s market penetration and its revenues evolution, the market acceptance of certain new technologies and products, the relevant cost structure, the discount rates applied using a weighted average cost of capital and the perpetuity rates used in calculating cash flow terminal values.

2.9 Intangible assets with definite useful lives

Intangible assets subject to amortization include intangible assets purchased from third parties recorded at cost and intangible assets acquired in business combinations initially recorded at fair value. Amortization begins when the intangible asset is available for its intended use. Amortization reflects the pattern in which the asset’s economic benefits are consumed, which usually consists in applying the straight-line method to allocate the cost of the intangible assets over their estimated useful lives.

The carrying value of intangible assets with definite useful lives is evaluated whenever changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for

the amount by which the asset’s carrying amount exceeds its fair value. The Company evaluates the remaining useful life of an intangible asset at each reporting date to determine whether events and circumstances warrant a revision to the remaining period of amortization.

Technologies and licenses

Separately acquired technologies and licenses are recorded at historical cost. Technologies and licenses acquired in a business combination are initially recognized at acquisition date fair value. Technologies and licenses have a useful life which usually ranges from 3 to 11 years and are carried at cost less accumulated amortization and impairment losses, if any.

Computer software

Separately acquired computer software is recorded at historical cost. Costs associated with maintaining computer software programs are expensed as incurred and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use. The capitalization of costs for internally generated software developed by the Company for its internal use begins when the preliminary project stage is completed and when the Company, implicitly or explicitly, authorizes and commits to funding a computer software project. It must be probable that the project will be completed and will be used to perform the function intended. Amortization of computer software begins when the software is available for its intended use and is calculated using the straight-line method over the estimated useful life, which does not exceed 4 years.

2.10 Property, plant and equipment

Property, plant and equipment are stated at historical cost, net of accumulated depreciation and any impairment losses. Property, plant and equipment acquired in a business combination are initially recognized at acquisition date fair value. Major additions and improvements are capitalized, while minor replacements and repairs are expensed and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use.

Land is not depreciated. Depreciation on fixed assets is computed using the straight-line method over their estimated useful lives, as follows:


Buildings						33 years
Facilities and leasehold improvements						5-10 years
Machinery and equipment						2-10 years
Computer and R&D equipment						3-6 years
Other						2-5 years

The Company also evaluates, and adjusts if appropriate, the assets’ useful lives.

Property, plant and equipment are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or a group of assets may not be recoverable. Several impairment indicators exist for making this assessment, such as: restructuring plans, significant changes in the technology, market, economic or legal environment in which the Company operates, available evidence of obsolescence of the asset, or indication that its economic performance is, or will be, worse than expected. In determining the recoverability of assets to be held and used, the Company initially assesses whether the carrying value of the tangible assets or group of assets exceeds the undiscounted cash flows associated with these assets. If exceeded, the Company then evaluates whether an impairment charge is required by determining if the asset’s carrying value also exceeds its fair value. This fair value is normally estimated by the Company based on independent market appraisals or the sum of discounted future cash flows, using market assumptions such as the utilization of the Company’s fabrication facilities and the ability to upgrade such facilities, change in the selling price and the adoption of new technologies. Any impairment loss is reported on the same income statement line as the depreciation expense recorded on the impaired group of assets, except in case of closure of operating sites or major restructuring plans and reorganizations. In such case, any impairment loss is reported on the line “Impairment, restructuring charges and other related closure costs” in the consolidated statements of income.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are included in “Other income and expenses, net” in the consolidated statements of income.

The Company did not hold any significant assets held for sale as of December 31, 2023 and December 31, 2022.

2.11 Leases

A lease contract is a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. If a lease is identified, classification between finance or operating is determined at lease commencement. Most leases entered by the Company are operating leases. Operating lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The rate implicit in the lease should be used as a discount rate whenever that rate is readily determinable. In most cases, this rate is not readily determinable and therefore, the Company uses its incremental borrowing rate, which is derived from information available at the lease commencement date. The Company considers its recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. Operating lease right-of-use assets are based on the corresponding lease liability adjusted for any lease payments made at or before commencement, initial direct costs, and lease incentives.

Right-of-use assets are included in the line “Property, plant and equipment, net” of the consolidated balance sheets. Operating lease liabilities due within one year are included in the line “Other payables and accrued liabilities”, while non-current operating lease liabilities are included in the line “Other long-term liabilities” of the Company’s consolidated balance sheets. Operating lease expenses are recognized in the consolidated statements of income, on a straight-line basis since the lease commencement date over the lease period and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Finance lease liabilities due within one year are included in the line “Short-term debt”, while non-current finance lease liabilities are included in the line “Long-term debt” of the Company’s consolidated balance sheets. Right-of-use assets for finance leases are depreciated on a straight-line basis since the lease commencement date over the lease period or the estimated useful life of the leased asset in case of transfer of ownership or purchase option that is reasonably certain to be exercised. The depreciation expense is reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Certain lease contracts contain options to extend the lease. On these contracts, the Company estimates the lease term by including the extended duration when it is reasonably certain for the Company to exercise that option. In addition, for short-term leases, defined as leases with a term of twelve months or less, the Company elected the practical expedient to not recognize an associated lease liability and right-of-use asset. The short-term lease election is made at the commencement date only. Additionally, lease contracts with a sum of lease payments not exceeding $5,000 are excluded from recognition on the consolidated balance sheet.

The right-of-use asset is a non-monetary asset while the lease liability is a monetary liability. When accounting for a lease that is denominated in a foreign currency, the lease liability is remeasured using the current exchange rate, while the right-of-use asset is measured using the historical exchange rate as of the commencement date.

The Company does not separate lease and non-lease components and instead accounts for each separate lease component and the non-lease components associated with that lease component as a single lease component.

Variable lease payments that depend on an index or a rate are included in the lease payments and are measured using the prevailing index or rate at the measurement date. Changes to index and rate-based variable lease payments are recognized in earnings in the period of the change.

2.12 Loss contingencies

In determining loss contingencies, the Company considers the likelihood of the incurrence of a liability as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss from a loss contingency is accrued when information available indicates that it is probable that a liability has been incurred at the date of the consolidated financial statements and when the amount of the loss can be reasonably estimated.

2.13 Long-term debt

(a)Convertible debt

On January 1, 2022, the Company adopted the new guidance on distinguishing liabilities from equity by applying the modified retrospective approach, with the impact upon transition recorded in retained earnings for instruments outstanding as of the date of adoption of the new guidance. Prior to the new guidance, components of convertible debt instruments that may be settled in cash upon conversion based on a net-share settlement basis were accounted for separately as long-term debt and equity when the conversion feature of the convertible bonds constituted an embedded equity instrument. When an equity instrument was identified, proceeds from issuance were allocated between debt and equity by measuring first the liability component and then determining the equity component as a residual amount. The liability component was measured as the fair value of a similar non-convertible debt, which resulted in the recognition of a debt discount. In subsequent periods, the Company amortized the debt discount through earnings in the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest method, based on the contractual maturity of the debt. The equity component, reported on the line “Additional paid-in capital” of the consolidated statement of equity, was not remeasured. Deferred taxes were recognized on the difference between the carrying amount of the liability component and its tax basis. In case of conversion from the bondholders, the fair value of the consideration transferred was allocated between the liability component and the equity component. The difference between the carrying amount of the debt at the settlement date and the fair value of the debt component was recorded in earnings as a loss on debt extinguishment and reported in the line “Loss on financial instruments, net” of the consolidated statements of income. The liability component was measured as the fair value of a similar non-convertible debt prior to settlement. The reacquired equity component was recorded in equity and reported on the line “Additional paid-in capital” of the consolidated statement of equity.

The new accounting guidance adopted on January 1, 2022 has eliminated the cash conversion model described above. At initial recognition, total cash proceeds received at issuance are reported as financial debt and no equity conversion instrument is recorded separately in equity. On subsequent periods, the carrying value of the convertible debt is incremented up to its nominal value over the amortization pattern of any unamortized debt discount and issuance costs.

Debt issuance costs are reported as a deduction of debt. They are subsequently amortized through earnings on the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest rate method.

(b)Bank loans

Bank loans and non-convertible senior bonds are recognized at the amount of cash proceeds received, net of debt issuance costs incurred. They are subsequently reported at amortized cost; any difference between the proceeds (net of debt issuance costs) and the principal amount is recognized through earnings on the line “Interest income (expense), net” of the consolidated statements of income over the period of the borrowings using the effective interest method.

2.14 Employee benefits

(a) Pension obligations

The Company sponsors various pension schemes for its employees. These schemes conform to local regulations and practices in the countries in which the Company operates. Such plans include both defined benefit and defined contribution plans. For defined benefit pension plans, the liability recognized in the consolidated balance sheets is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The funded status of the defined benefit plans is calculated as the difference between plan assets and the projected benefit obligations. Estimates are used in determining the assumptions incorporated in the calculation of the pension obligations, which is supported by input from independent actuaries. Actuarial gains and losses arising from changes in actuarial assumptions are recognized in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity and are charged or credited to earnings over the employees’ average remaining service period using the corridor amortization method. Past service costs are recognized in earnings on the line “Other components of pension benefit costs” of the consolidated statements of income if the changes to the pension scheme are not conditional on the employees remaining in service for a specified period. Other past service costs are recognized in “Accumulated other comprehensive income (loss)”

in the consolidated statements of equity and are amortized on a straight-line basis over the average remaining service period. The net periodic benefit cost of the year is determined based on the assumptions used at the end of the previous year.

The service cost component of net periodic benefit costs is presented in the same income statement line as other employee compensation costs arising from services rendered during the period. The other components of the net periodic benefit cost are presented separately, outside operating income, on the line “Other components of pension benefit costs” of the consolidated statements of income. These elements include: interest cost; expected return on plan assets; amortization of transition (asset) obligation; amortization of prior service cost; amortization of net (gain) loss; (gain) loss recognized due to curtailment or settlement and; cost of special termination benefits.

For defined contribution pension plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

(b) Termination benefits

Termination benefits are payable when an employee is involuntarily terminated, or whenever an employee accepts voluntary termination in exchange for termination benefits. For the accounting treatment and timing of recognition of involuntary termination benefits, the Company distinguishes between one-time termination benefit arrangements and ongoing termination benefit arrangements. A one-time termination benefit arrangement is established by a termination plan and applies to a specified termination event. One-time involuntary termination benefits are recognized as a liability when the termination plan meets certain criteria and has been communicated to employees. If employees are required to render future service in order to receive these one-time termination benefits, the liability is recognized ratably over the future service period. Termination benefits other than one-time termination benefits are termination benefits for which the communication criterion is not met but that are committed to by management, or termination obligations that are not specifically determined in a new and single plan. These termination benefits are all legal, contractual and past practice termination obligations to be paid to employees in case of involuntary termination. These termination benefits are accrued for when commitment creates a present obligation to others for the benefits expected to be paid, when it is probable that employees will be entitled to the benefits and the amount can be reasonably estimated.

In case of special termination benefits related to voluntary redundancy programs, the Company recognizes a provision for voluntary termination benefits at the date on which the employee irrevocably accepts the offer and the amount can be reasonably estimated.

The Company recognizes a liability and an expense for bonuses and profit-sharing plans when a contractual obligation exists or when there is a past practice that has created a present obligation.

(d) Other long-term employee benefits

The Company provides long-term employee benefits such as seniority awards in certain countries. The entitlement to these benefits is usually conditional on the employee completing a minimum service period. The expected costs of these benefits are accrued over the period of employment. Actuarial gains and losses arising from changes in actuarial assumptions are charged or credited to earnings in the period of the revised estimate. These obligations are valued annually with the assistance of independent qualified actuaries.

(e) Share-based compensation

The Company accounts for stock-based compensation for all stock-based awards granted to senior executives and selected employees, including awards that vest upon the satisfaction of a service condition and awards that vest upon the satisfaction of both a service condition and a performance condition. Both equity awards vest over

a three-year service period while performance-based awards also require the Company’s attainment of certain performance conditions. The Company measures the cost of the awards based on the related grant-date fair value, reflecting the market price of the underlying shares at the date of the grant, reduced by the present value of the dividends expected to be paid during the requisite service period. That cost is recognized ratably over the period during which an employee is required to provide service in exchange for the award. The compensation cost is recorded through earnings with the corresponding amount reported in equity, under “Additional paid-in capital” of the consolidated statements of equity. The compensation cost is calculated based on the number of awards expected to vest, net of an estimated number of awards to be forfeited due to the employees failing to satisfy the service condition or one or more performance conditions. By the end of the vesting period, compensation is recognized only for the awards that ultimately vest.

Liabilities for the Company’s portion of payroll taxes are recognized at vesting, which is the event triggering the payment of the social contributions in most of the Company’s local tax jurisdictions. Employee-related social charges are measured based on the intrinsic value of the share and recorded at vesting date.

2.15 Share capital

Ordinary shares are classified as “Common stock” within equity on the consolidated balance sheets. Incremental costs directly attributable to the issuance of new shares are shown in equity as a deduction, net of tax, from the proceeds received.

Where the Company purchases its own equity share capital (treasury stock), the consideration paid, including any directly attributable incremental costs (net of income taxes), is deducted from parent company stockholders’ equity until the shares are cancelled, reissued, or disposed of.

2.16 Comprehensive income (loss)

Comprehensive income (loss) is defined as the change in equity of a business during a period except those changes resulting from investment by and distributions to stockholders. In the consolidated financial statements, “Other comprehensive income (loss)” and “Accumulated other comprehensive income” primarily consists of foreign currency translation adjustments, unrealized gains (losses) on debt securities classified as available-for-sale, unrealized gains (losses) on derivatives designated as cash flow hedge and the accounting for defined benefit plans, net of tax.

2.17 Revenue recognition

Arrangements with customers are considered contracts if all the following criteria are met: (a) parties have approved the contract and are committed to perform their respective obligations; (b) each party’s rights regarding the goods or services to be transferred can be identified; (c) payment terms for the goods or services to be transferred can be identified; (d) the contract has commercial substance and (e) collectability of substantially all of the consideration is probable. The Company recognizes revenue from products sold to a customer, including distributors, when it satisfies a performance obligation by transferring control over a product to the customer. The Company may also enter into several multi-annual capacity reservation and volume commitment arrangements with certain customers. These agreements constitute a binding commitment for the customers to purchase and for the Company to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities.

In certain circumstances, the Company may enter into agreements that concern principally revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to the customer. The payment terms typically range between 30 to 90 days. Certain customers require the Company to hold inventory as consignment in their hubs and only purchase inventory when they require it. Revenue for sales of such inventory is recognized when, at the customer’s option, the products are withdrawn from the consignment and the Company satisfies a performance obligation by transferring control over a product to the customer.

Consistent with standard business practice in the semiconductor industry, price protection is granted to distribution customers on their existing inventory of the Company’s products to compensate them for changes in market prices. The Company accrues a provision for price protection based on a rolling historical price trend computed monthly as a percentage of gross distributor sales. This historical price trend represents differences in recent months between the invoiced price and the final price to the distributor, adjusted to accommodate a significant change in the selling price. The short outstanding inventory time, visibility into the inventory product pricing and long distributor pricing history have enabled the Company to reliably estimate price protection provisions at period-end. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income at the time of the sale.

The Company’s customers occasionally return the Company’s products for technical reasons. The Company’s standard terms and conditions of sale provide that if the Company determines that products do not conform, the Company will repair or replace the non-conforming products, or issue a credit note or rebate of the purchase price. Quality returns are identified shortly after sale in customer quality control testing. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income, using contractual and historical information.

The Company records a provision for warranty costs as a charge against “Cost of sales” in the consolidated statements of income, based on historical trends of warranty costs incurred as a percentage of sales, which management has determined to be a reasonable estimate of the probable losses to be incurred for warranty claims in a period. Any potential warranty claims are subject to the Company’s determination that the Company is at fault for damages, and such claims must usually be submitted within a short period of time following the date of sale. This warranty is given in lieu of all other warranties, conditions or terms expressed or implied by statute or common law. The Company’s contractual terms and conditions typically limit its liability to the sales value of the products which gave rise to the claims.

The Company’s insurance policy relating to product liability covers third-party physical damages and bodily injury, indirect financial damages as well as immaterial non-consequential damages caused by defective products.

In addition to product sales, the Company enters into arrangements with customers consisting in transferring licenses or related to license services. The revenue generated from these arrangements are reported on the line “Other revenues” of the consolidated statements of income.

2.18 Public funding

The Company receives funding from several governmental agencies and income is recognized when all contractual conditions for receipt of these funds are fulfilled and eligible expenditures incurred. Such funding is generally provided to encourage research, development and other innovation activities, industrialization deployment and local economic development. The conditions to receive government funding may include eligibility restrictions, approval by the local governmental authorities, annual budget appropriations, compliance with regulations, as well as specifications regarding objectives and results. Certain specific contracts include obligations to maintain a minimum level of employment and investment during a certain period. There could be penalties if these objectives are not fulfilled. Other contracts contain penalties for breach of contract, which may result in repayment obligations. Funding related to these contracts is recorded when the conditions required by the contracts are met. The Company’s funding programs are classified under two general categories: funding for research, development and other innovative activities, and capital investments.

Funding for research, development and innovative activities is the most common form of funding that the Company receives. This public funding is recorded as “Other income and expenses, net” in the consolidated statements of income. The funding is recognized ratably as the related costs are incurred once the agreement with the respective governmental agency has been signed and all applicable conditions are met. Other government assistance, such as funding received for industrialization deployment and local economic development in certain regions, are reported as a deduction of cost of sales or other operating expenses according to the nature of the underlying costs eligible to the grants.

French research tax credits (“Crédit Impôt Recherche”) and Italian research tax credits (“Credito d’Imposta Ricerca & Sviluppo”) are deemed to be grants in substance. The French research tax credits are to be paid in cash by the taxing authorities within three years in case they are not deducted from income tax payable during

this period of time. The Italian tax credits are compensated against payroll-related social charges. French and Italian tax credits are reported as a reduction of “Research and development expenses” in the consolidated statements of income.

Capital investment funding is recorded as a reduction of “Property, plant and equipment, net” on the consolidated balance sheets when the Company has incurred the eligible capital expenditures and when all conditions for eligibility have been fulfilled. Advances from capital grants received on capital investments that have not been incurred yet are reported as in the line "Other long-term liabilities" on the consolidated balance sheets. Capital investment funding is recognized in the Company’s consolidated statements of income by offsetting the depreciation charges of the funded assets during their useful lives. The Company also receives funding, which can be recovered through the reduction of various governmental liabilities, including income tax, value-added tax and employee-related social charges.

Funding receivables are reported as non-current assets unless cash settlement features of the receivables evidence that collection is expected within one year. Long-term receivables that do not present any tax attribute or legal restriction are reflected in the consolidated balance sheets at their net present value when the discounting effect is deemed to be significant.

2.19 Research and development

Research and development expenses include costs incurred by the Company, the Company’s share of costs incurred by other research and development interest groups, and costs associated with co-development contracts. Research and development expenses do not include marketing design center costs, which are accounted for as “Selling, general and administrative expenses” in the consolidated statements of income and process engineering, pre-production or process transfer costs which are recorded as “Cost of sales” in the consolidated statements of income. Research and development costs are expensed as incurred. The amortization expense recognized on technologies and licenses purchased by the Company from third parties to facilitate the Company’s research and development activities is reported as “Research and development expenses” in the consolidated statements of income.

2.20 Advertising costs

Advertising costs are expensed as incurred and are recorded as “Selling, general and administrative expenses” in the consolidated statements of income. Advertising expenses for 2023, 2022 and 2021 were $23 million, $18 million and $12 million, respectively.

2.21 Start-up and phase-out costs

Start-up costs represent costs incurred in the ramp-up phase of the Company's newly integrated manufacturing facilities. The costs of phase-outs are associated with the latest stages of facilities closure when the relevant production volumes become immaterial. Start-up costs and phase-out costs are included in the line “Other income and expenses, net” of the consolidated statements of income.

2.22 Investments in equity securities

Investments in equity securities that have readily determinable fair values and for which the Company does not have the ability to exercise significant influence are classified as equity securities measured at fair value through earnings. Changes in the fair value of these securities are reported in the consolidated statements of income within “Other income and expenses, net” when these instruments are held within the Company’s operating activities. Gains and losses arising from changes in the fair value of securities not related to operating activities are presented in the consolidated statements of income as non-operating elements within “Gain (loss) on financial instruments, net” in the period in which they arise. The fair values of quoted equity securities are based on current market prices. If the market for a financial asset is not active or if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

For investments in equity securities without readily determinable fair values and for which the Company does not have the ability to exercise significant influence, the Company has elected to apply the cost method as a measurement alternative. Under the cost method of accounting, investments are carried at historical cost, less impairment. An impairment loss is recorded when there are identified events or changes in circumstances that may have a significant adverse effect on the value of the investment. Loss is immediately recorded in the consolidated statements of income on the line “Gain (loss) on financial instruments, net” and is based on the Company’s assessment of any significant and sustained reductions in the investment’s value. Gains and losses on investments sold are determined on the specific identification method and are recorded as non-operating element in the line “Gain (loss) on financial instruments, net” of the consolidated statements of income when the transaction is not related to operating activities.

The Company did not hold any material equity securities as of December 31, 2023 and December 31, 2022.

2.23 Investments in debt securities

Debt securities are included in current assets when they represent investments of funds available for current operations.

Changes in fair value of debt securities classified as available-for-sale are recognized as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income. The Company assesses at each balance sheet date whether there is objective evidence that a debt security or group of debt securities is impaired. An unrealized impairment loss exists when the fair value of the instrument declines below its amortized cost basis. An impairment loss is recognized in earnings, through a direct reduction of the value of the asset, when the Company intends to sell the debt security or when it is more likely than not that the Company will be required to sell the instrument before recovery of the amortized cost basis. Moreover, an impairment loss is recognized in earnings through a credit loss allowance for any portion of the unrealized impairment loss resulting from a credit loss. Impairment losses recognized in the consolidated statements of income are not reversed through earnings.

The fair values of quoted debt securities are based on current market prices. If the market for a financial asset is not active and if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

The Company did not hold any debt securities classified as held-to-maturity or for which the Company would have elected to apply the fair value option.

2.24 Derivative financial instruments and hedging activities

Derivative financial instruments are initially recognized on the date a derivative contract is entered into and are subsequently measured at fair value. The method of recognizing the gain or loss resulting from the derivative instrument depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the hedge transaction. The Company has designated certain derivatives as hedges of a particular risk associated with a highly probable forecasted transaction (cash flow hedge).

The Company documents, at inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. The Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. Derivative instruments that are not designated as hedges are measured at fair value through earnings.

Cash Flow Hedge

As part of its ongoing operating, investing and financing activities, the Company enters into certain derivative transactions that may be designated and may qualify as hedging instruments. To reduce its exposure to U.S. dollar exchange rate fluctuations, the Company hedges certain Euro-denominated forecasted transactions that cover at reporting date a large part of its research and development, and selling, general and administrative expenses as well as a portion of its front-end manufacturing costs of semi-finished goods within cost of sales

through the use of currency forward contracts and currency options, including collars. The Company also hedges through the use of currency forward contracts certain Singapore dollar-denominated manufacturing forecasted transactions.

The derivative instruments are designated and qualify for cash flow hedge at inception of the contract and on an ongoing basis over the duration of the hedge relationship. They are reflected at their fair value as “Other current assets” or “Other payables and accrued liabilities” in the consolidated balance sheets when settlement is expected to occur within twelve months after the reporting date. They are reported as "Other non-current assets" or "Other long-term liabilities" in the consolidated balance sheets when settlement is expected beyond twelve months. The criteria for designating a derivative as a hedge include the instrument’s effectiveness in risk reduction and matching of the derivative instrument to its underlying transactions with the critical terms of the hedging instrument matching the terms of the hedged forecasted transaction. This enables the Company to conclude that changes in cash flows attributable to the risk being hedged are expected to be substantially offset by the hedging instruments.

For derivative instruments designated as cash flow hedge, the change in fair value for the effective portion of the hedge is reported as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income and is reclassified into earnings in the same period in which the hedged transaction affects earnings, and within the same consolidated statements of income line as the hedged transaction. For these derivatives, ineffectiveness appears if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. Effectiveness on transactions hedged through purchased options is measured on the full fair value of the option, including time value.

Derivative financial instruments not designated as a hedge

The Company conducts its business on a global basis in various major international currencies. As a result, the Company is exposed to adverse movements in foreign currency exchange rates. The Company enters into foreign currency forward contracts and currency options to reduce its exposure to changes in exchange rates and the associated risk arising from the denomination of certain assets and liabilities in foreign currencies at the Company's subsidiaries.

Financial instruments not designated as a hedge are classified as current assets when they are expected to be realized within twelve months of the balance sheet date. Marked-to-market gains or losses arising from changes in the fair value of these instruments are reported in the consolidated statements of income within “Other income and expenses, net” in the period in which they arise, since the transactions for these instruments occur within the Company’s operating activities.

2.25 Recent accounting pronouncements

(a)Accounting pronouncements effective in 2023

No new guidance was adopted in 2023 with a significant impact on the Company's financial statements, financial positions and operations.

(b)Accounting pronouncements expected to impact the Company’s operations that are not yet effective and have not been early adopted by the Company

In November 2023, the FASB issued new guidance related to segment reporting, which requires incremental disclosures about reportable segments, without changing though the definition of a segment or the guidance for determining reportable segments. The new guidance requires disclosures of significant segment expenses that are (i) regularly provided to (or easily computed from information regularly provided to) the chief operating decision maker ("CODM"); (ii) included in the reported measure of segment profit or loss. The new guidance also requires that an entity discloses, on an annual and interim basis, an amount for "other segment items" by reportable segment, and a description of its composition. Moreover, annual disclosures about a reportable segment's profit or loss and assets become mandatory on interim periods. Finally, the title and position of the CODM, together with an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources, are also required. The guidance is effective for the Company's 2024 annual reporting and 2025 interim periods. The guidance will be applied retrospectively, with early adoption permitted. The Company will adopt the new guidance when effective and is currently assessing the impact the new guidance will have on its segment reporting.

In December 2023, the FASB issued new guidance related to income taxes, which requires additional disclosures, primarily around disaggregation of income tax paid and specific categories in the income tax rate reconciliation. The guidance is effective for the year ended December 31, 2025, with early adoption permitted. The guidance will be applied prospectively. Retrospective application is permitted. The Company is currently assessing the impact the new guidance will have on its annual income tax disclosures.

LONG-TERM DEBT

Long-term debt consisted of the following:


	December 31,	December 31,
	2023	2022
Funding program loans from European Investment Bank ("EIB"):
4.72% due 2028, floating interest rate at Euribor +0.589%	141	163
4.52% due 2029, floating interest rate at Euribor +0.564%	162	183

1.75% due 2042, fixed interest rate	2	—
Other funding program loans:
0.29% (weighted average), due 2024-2028, fixed interest rate	5	4


Total long-term debt	2,927	2,717
Less current portion	(217)	(175)
Total long-term debt, less current portion	2,710	2,542

Long-term debt is denominated in the following currencies:


	December 31, 2023	December 31, 2022
U.S. dollar	1,496	1,495
Euro	1,431	1,222
Total	2,927	2,717

On August 4, 2020, the Company issued a $1.5 billion principal amount of dual tranche senior unsecured convertible bonds (Tranche A and Tranche B for $750 million each tranche), due 2025 and 2027, respectively. Tranche A bonds were issued at 105.8% as zero-coupon bonds while Tranche B bonds were issued at 104.5% as zero-coupon bonds. The conversion price at issuance was $43.62 for Tranche A equivalent to a 47.5% conversion premium and $45.10 for Tranche B, equivalent to a 52.5% conversion premium. These conversion features correspond to an equivalent of 4,585 shares per each Tranche A bond $200,000 par value and an equivalent of 4,435 shares per each Tranche B bond $200,000 par value. The bonds are convertible by the bondholders or are callable by the issuer upon certain conditions, on a net-share settlement basis, except if the

issuer elects a full-cash or full-share conversion as an alternative settlement. The net proceeds from the bond offering were $1,567 million, after deducting issuance costs paid by the Company.

As per contractual terms, the bondholders have full conversion rights on Tranche A bonds, starting August 2023. In terms of Tranche B, up until August 2024, the bonds can be converted by the bondholders with a contingent feature of 130% of the conversion price, measured at quarter-end for the following quarter. After that date, the bondholders will have full conversion rights.

As per contractual terms, starting August 2023, Tranche A bonds are callable by the Company with a 130% contingent feature, with the exercise of its call rights being preceded by the release, by the Company, of an Optional Redemption Notice. The same feature applies for Tranche B bonds but only after August 2024.

As of December 31, 2023, the Company stock price exceeded the conversion price of the senior unsecured convertible bonds. However, the 130% stock price contingent feature was not met. Consequently, Tranche A bonds are not callable by the Company and bondholders cannot exercise their conversion rights on Tranche B bonds.

The convertible debt was reported as Long-term debt in the consolidated balance sheets as of December 31, 2023 and December 31, 2022, based on its original maturity, after having considered several factors, such as the uncertainty around the timing of the potential exercise of the conversion rights by bondholders and the call rights by the Company.

Aggregate future maturities of total long-term debt (including current portion) at principal amount are as follows:


						December 31,
						2023
2024						217
2025						962
2026						212
2027						947
2028						198
Thereafter						395
Total						2,931

The difference between the total aggregated future maturities in the preceding table and the total carrying amount of long-term debt is due to unamortized issuance costs on the dual tranche senior unsecured convertible bonds.

Credit facilities

The Company’s long-term debt contained standard conditions but does not impose minimum financial ratios. The Company had unutilized committed medium-term credit facilities with core relationship banks totalling $1,030 million as of December 31, 2023.

The EIB Loans are comprised of three long-term amortizing credit facilities as part of R&D funding programs. The first one, signed in August 2017, is a €500 million loan in relation to R&D and capital expenditures in the European Union for the years 2017 and 2018. The entire amount was fully drawn in Euros corresponding to $303 million outstanding as of December 31, 2023. The second one, signed in 2020, is a €500 million credit facility agreement with EIB to support R&D and capital expenditure programs in Italy and France. The amount was fully drawn in Euros representing $442 million outstanding as of December 31, 2023. In 2022, the Company signed a third long-term amortizing credit facility with EIB of €600 million, out of which, €300 million was withdrawn representing $332 million outstanding as of December 31, 2023. In January 2024, an amount of $300 million was withdrawn under this credit facility.

The CDP loans are comprised of two long-term credit facilities. The first, signed in 2021, is a €150 million loan, fully drawn in Euros, of which $97 million were outstanding as of December 31, 2023. The second one, signed in 2022, is a €200 million loan, fully drawn in Euros, of which $187 million was outstanding as of December 31, 2023.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

– Senior unsecured convertible bonds issued on August 4, 2020 (2)	1	1,496	1,814	1,495	1,561

(1) Cash equivalents primarily correspond to deposits at call with banks.

(2) The carrying amount as of December 31, 2023, of the senior unsecured convertible bonds as reported above, corresponds to the nominal value of the bonds, net of $4 million unamortized debt issuance costs. The fair value represented the market price of the bonds trading on the Frankfurt Stock Exchange.

Schedule of Methodologies Used to Estimate Fair Value

The methodologies used to estimate fair value are as follows:


Components			Methodology used to estimate fair value
Debt securities classified as available-for-sale			Quoted market prices for identical instruments
Foreign exchange forward contracts, currency options and collars			Quoted market prices for similar instruments
Equity securities measured at fair value through earnings			Quoted market prices for identical instruments
Equity securities carried at cost as a measurement alternative			Valuation of the underlying investments on a new round of third-party financing or upon liquidation
Long-term debt and current portion of long-term debt			Future cash flows on a borrowing-by-borrowing basis and discounting these future cash flows using the Company's incremental borrowing rates for similar types of borrowing arrangements. For convertible bonds, the fair value represents the market price of the bonds trading on the Frankfurt Stock Exchange
Cash and cash equivalents, short-term deposits, accounts receivable, short-term borrowings, and accounts payable			The carrying amounts reflected in the consolidated financial statements are considered as reasonable estimates of fair value due to the relatively short period of time between the origination of the instruments and their expected realization.

Revenues

12 Months Ended

Dec. 31, 2023

Revenue from Contract with Customer [Abstract]

Revenues

REVENUES

19.1 Nature of goods and services

The Company designs, develops, manufactures and markets a broad range of products, including discrete and standard commodity components, application-specific integrated circuits (“ASICs”), full-custom devices and semi-custom devices and application specific standard products (“ASSPs”) for analog, digital and mixed-signal applications. In addition, the Company participates in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

The principal activities – separated by reportable segments – from which the Company generates its revenues are described in Note 20.

Other revenues consist of license revenue, service revenue related to transferring licenses, patent royalty income, sale of scrap materials and manufacturing by-products.

While the majority of the Company’s sales agreements contain standard terms and conditions, the Company may, from time to time, enter into agreements that contain multiple performance obligations or terms and conditions. Those agreements concern principally the revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to the customer.

19.2 Revenue recognition and disaggregation

The Company recognizes revenue from products sold to a customer, including distributors, when it satisfies a performance obligation at a point in time by transferring control over a product to the customer. This usually occurs at the time of shipment. The performance obligations linked to the sale of goods contracts have the original expected length of less than one year. The transaction price is determined based on the contract terms, adjusted for price protection, if applicable. The revenues from services are usually linked to performance obligations transferred over time and are recognized in line with the contract terms.

In 2023 and 2022, the Company signed several multi-annual capacity reservation and volume commitment arrangements with certain customers. These agreements constitute a binding commitment for the customers to purchase and for the Company to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities. Advances from customers received as part of those agreements are described in Note 14 and Note 17.

The payment terms typically range between 30 to 90 days.

The Company’s consolidated net revenues disaggregated by reportable segment are presented in Note 20. The following tables present the Company’s consolidated net revenues disaggregated by geographical region of shipment, nature and market channel:


	Year ended
	December 31, 2023	December 31, 2022	December 31, 2021
Net revenues by geographical region of shipment(1)
EMEA	4,836	3,619	2,557

Total net revenues	17,286	16,128	12,761

Distribution	5,818	5,364	4,275
Total net revenues	17,286	16,128	12,761

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which the Company has the right to invoice for services performed.

In 2023, 2022 and 2021, the Company’s largest customer, Apple, represented 12.3%, 16.8% and 20.5% of consolidated net revenues, respectively, reported in the ADG, AMS and MDG segments.

Other Current Assets

OTHER CURRENT ASSETS

Other current assets are detailed below:


	December 31, 2023	December 31, 2022
Public funding receivables	651	190
Taxes and other government receivables	241	270
Advances and prepayments	180	125
Loans and deposits	10	10
Interest receivable	27	22
Derivative instruments	58	56
Other current assets	128	61
Total	1,295	734

Public funding receivables are described in Note 7.

Taxes and other government receivables mainly include receivables related to value-added tax, primarily in European tax jurisdictions.

Advances and prepayments include prepaid amounts associated with multi-annual supply and service agreements.

Derivative instruments are further described in Note 26.

Other current assets include a $28 million contribution to be received in 2024 from a third party as part of a collaborative agreement associated with the ongoing capacity expansion project for the 300mm wafer fab in Crolles, France. Total contributions received from the third party as part of this collaborative agreement totaled $54 million, reported as "Proceeds from capital grants and other contributions" in the statement of cash flows for the year ended December 31, 2023.

The Company applies a current expected credit losses model on all financial assets measured at amortized cost, including deposits, loans and receivables. The major portion of other current assets to which this model applies corresponds to government receivables. Due to the existing history of zero-default on receivables originated by governments, the expected credit losses are assumed to be not significant as of December 31, 2023 and December 31, 2022. Other current assets presented in the table above within the lines “Loans and deposits” and “Other current assets” are composed of amounts not deemed at exposure of default. Consequently, no loss allowance was reported on those current assets as of December 31, 2023 and December 31, 2022.

Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION

The Company designs, develops, manufactures and markets a broad range of products, including discrete and standard commodity components, ASICs, full custom devices and semi-custom devices and ASSPs for analog, digital, and mixed-signal applications. In addition, the Company further participates in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

As of December 31, 2023, the Company’s reportable segments were as follows:

•Automotive and Discrete Group (ADG), comprised of dedicated automotive integrated circuits (“ICs”), and discrete and power transistor products.

•Analog, MEMS and Sensors Group (AMS), comprised of analog, smart power, MEMS sensors and actuators, and optical sensing solutions.

•Microcontrollers and Digital ICs Group (MDG), comprised of general-purpose microcontrollers and microprocessors, connected security products (e.g. embedded secured elements and NFC readers), memories (e.g. serial and page EEPROM) and RF and Communications products.

Net revenues of “Others” include revenues from sales assembly services and other revenues. For the computation of the segments’ internal financial measurements, the Company uses certain internal rules of allocation for the costs not directly chargeable to the segments, including cost of sales, SG&A expenses and a part of R&D expenses. In compliance with the Company’s internal policies, certain costs are not allocated to the segments, but reported in “Others”. Those comprise unused capacity charges, including reduced manufacturing activity due to COVID-19 and incidents leading to power outage, impairment, restructuring charges and other related closure costs, management reorganization expenses, start-up and phase-out costs, and other unallocated

income (expenses) such as: strategic or special R&D programs, certain corporate-level operating expenses, patent claims and litigations, and other costs that are not allocated to product groups, as well as operating earnings of other products. In addition, depreciation and amortization expense is part of the manufacturing costs allocated to the segments and is neither identified as part of the inventory variation nor as part of the unused capacity charges; therefore, it cannot be isolated in cost of sales. Finally, public grants are allocated to the Company’s segments proportionally to the incurred expenses on the sponsored projects.

Wafer costs are allocated to the segments based on actual cost. From time to time, with respect to specific technologies, wafer costs are allocated to segments based on market price.

The following tables present the Company’s consolidated net revenues and consolidated operating income by reportable segment.

Net revenues by reportable segment:


	December 31, 2023	December 31, 2022	December 31, 2021

Others(1)	(414)	(97)	(23)
Total consolidated operating income	4,611	4,439	2,419

(1)Operating income (loss) of “Others” includes items such as unused capacity charges, including unloading charges due to COVID-19 and incidents leading to power outage, impairment, restructuring charges and other related closure costs, management reorganization costs, start-up and phase-out costs, and other unallocated expenses such as: strategic or special R&D programs, certain corporate-level operating expenses, patent claims and litigations, and other costs that are not allocated to product groups, as well as operating earnings of other products.

The reconciliation of operating income of reportable segments to the total consolidated operating income is presented in the below table:


	December 31, 2023	December 31, 2022	December 31, 2021

The following is a summary of operations by entities located within the indicated geographic areas for 2023, 2022 and 2021. Net revenues represent sales to third parties from the country in which each subsidiary is domiciled. The Company is incorporated under Dutch law with head offices located in the Netherlands while the Company’s operational office and headquarters are located in Switzerland. Long-lived assets consist of property, plant and equipment, net. A significant portion of property, plant and equipment expenditures is attributable to front-end and back-end facilities, located in the different countries in which the Company operates. As such, the Company mainly allocates capital spending resources according to geographic areas rather than along product segment areas.

Fair Value Disclosures [Abstract]

Financial Instruments and Risk Management

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

26.1 Financial risk factors

The Company is exposed to changes in financial market conditions in the normal course of business due to its operations in different foreign currencies and its ongoing investing and financing activities. The Company’s activities expose it to a variety of financial risks: market risk (including foreign exchange risk, fair value interest rate risk, cash flow interest rate risk and price risk), credit risk and liquidity risk. The Company’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance. The Company uses derivative financial instruments to hedge certain risk exposures.

Financial risk management is carried out by a central treasury department (Corporate Treasury). Additionally, a Treasury Committee, chaired by the Chief Financial Officer, steers treasury activities and ensures compliance with corporate policies. Treasury activities are thus regulated by the Company’s policies, which define procedures, objectives and controls. The policies focus on managing financial risk in terms of exposure to market risk, credit risk and liquidity risk. Treasury controls are subject to internal audits. Most treasury activities are centralized, with any local treasury activities subject to oversight from Corporate Treasury. Corporate Treasury identifies, evaluates and hedges financial risks in close cooperation with the Company’s subsidiaries. It provides written principles for overall risk management, as well as written policies covering specific areas, such as foreign exchange risk, interest rate risk, price risk, credit risk, use of derivative financial instruments, and investments of excess liquidity.

The majority of cash and cash equivalents is held in U.S. dollars and Euros and is placed with financial institutions rated at least a single “A” long-term rating from two of the major rating agencies, meaning at least A3 from Moody’s and A- from S&P and Fitch, or better. These ratings are closely and continuously monitored in order to manage exposure to the counterparty’s risk. Hedging transactions are performed only to hedge exposures deriving from operating, investing and financing activities conducted in the normal course of business.

Market risk

Foreign exchange risk

The Company conducts its business globally in various major international currencies. As a result, the Company is exposed to adverse movements in foreign currency exchange rates, primarily regarding the Euro. Foreign exchange risk mainly arises from recognized assets and liabilities at the Company’s subsidiaries and future commercial transactions.

Management has set up a policy to require the Company’s subsidiaries to hedge their entire foreign exchange risk exposure with the Company through financial instruments transacted or overseen by Corporate Treasury. Subsidiaries use forward contracts and purchased currency options to manage their foreign exchange risk arising from foreign-currency-denominated assets and liabilities. Foreign exchange risk arises when recognized assets and liabilities are denominated in a currency that is not the entity’s functional currency. These instruments do not qualify as hedging instruments for accounting purposes. Forward contracts and currency options, including collars, are also used by the Company to reduce its exposure to U.S. dollar fluctuations in Euro-denominated forecasted transactions that cover a large part of its R&D and corporate costs expenses as well as a portion of its front-end manufacturing costs of semi-finished goods. The Company also hedges through the use of currency forward contracts certain Singapore dollar-denominated manufacturing forecasted transactions. The derivative instruments used to hedge these forecasted transactions meet the criteria for designation as cash flow hedge. The hedged forecasted transactions have a high probability of occurring for hedge accounting purposes.

It is the Company’s policy to have the foreign exchange exposures in all the currencies hedged month by month against the monthly standard rate. At each month end, the forecasted flows for the coming month are hedged together with the fixing of the new standard rate. For this reason, the hedging transactions will have an exchange rate very close to the standard rate at which the forecasted flows will be recorded in the following month. As such, the foreign exchange exposure of the Company, which consists of the balance sheet positions and other contractually agreed transactions, is always close to zero and any movement in the foreign exchange rates will therefore not influence the exchange effect on items of the consolidated statement of income. Any discrepancy between the forecasted values and the actual results is constantly monitored and prompt actions are taken, if needed.

Derivative Instruments Not Designated as a Hedge

The Company enters into foreign currency forward contracts to reduce its exposure to changes in exchange rates and the associated risk arising from the denomination of certain assets and liabilities in foreign currencies at the Company’s subsidiaries. These include receivables from international sales by various subsidiaries, payables for foreign currency-denominated purchases and certain other assets and liabilities arising from intercompany transactions.

The notional amount of these financial instruments totaled $974 million, $931 million and $505 million on December 31, 2023, 2022 and 2021, respectively. The principal currencies covered at the end of the year 2023 are the China Yuan Renminbi, the Singapore dollar, the Euro, the Japanese yen, the Swiss franc, the Indian rupee, the Malaysian ringgit, the Moroccan dirham, the Philippines peso, the Swedish krona, the Taiwan dollar, and the South Korean won.

The risk of loss associated with forward contracts is equal to the exchange rate differential from the time the contract is entered into until the time it is settled. The risk of loss associated with purchased currency options is equal to the premium paid when the option is not exercised.

Foreign currency forward contracts not designated as cash flow hedge outstanding as of December 31, 2023 have remaining terms of 3 days to 166 days, maturing on average after 47 days.

Derivative Instruments Designated as a Hedge

To further reduce its exposure to U.S. dollar exchange rate fluctuations, the Company hedges through the use of currency forward contracts and currency options, including collars, certain Euro-denominated forecasted intercompany transactions that cover at year-end a large part of its R&D and SG&A expenses, as well as a portion of its front-end manufacturing costs of semi-finished goods within cost of sales. The Company also hedges through the use of currency forward contracts certain manufacturing transactions within cost of sales denominated in Singapore dollars.

The principles regulating the hedging strategy for derivatives designated as cash flow hedge are established as follows: (i) for R&D and corporate costs, up to 80% of the total forecasted transactions; (ii) for manufacturing costs, up to 70% of the total forecasted transactions. In order to follow a dynamic hedge strategy, the Company may change the percentage of the designated hedged item within the limit of 100% of the forecasted transaction. The maximum length of time over which the Company could hedge its exposure to the variability of cash flows for forecasted transactions is 24 months.

For the year ended December 31, 2023, the Company recorded a decrease in cost of sales of $1 million and a decrease in operating expenses of $4 million, related to the realized gains incurred on such hedged transactions. For the year ended December 31, 2022, the Company recorded an increase in cost of sales of $129 million and an increase in operating expenses of $68 million, related to the realized losses incurred on such hedged transactions. For the year ended December 31, 2021, the Company recorded a decrease in cost of sales of $15 million and a decrease in operating expenses of $4 million, related to the realized gains incurred on such hedged transactions.

The notional amount of foreign currency forward contracts and currency options, including collars, designated as cash flow hedge totaled $2,681 million, $3,192 million and $2,165 million on December 31, 2023, 2022 and 2021, respectively. The forecasted transactions hedged as of December 31, 2023 were determined to have a high probability of occurring.

As of December 31, 2023, $55 million of deferred gains on derivative instruments included in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity were expected to be reclassified as earnings during the next 12 months based on the monthly forecasted R&D expenses, corporate costs and semi-finished manufacturing costs. Foreign currency forward contracts and collars designated as cash flow hedge outstanding as of December 31, 2023 have remaining terms of 4 days to 13 months, maturing on average after 113 days.

As of December 31, 2023, the Company had the following outstanding derivative instruments that were entered into to hedge Euro-denominated and Singapore dollar-denominated forecasted transactions:


In millions of Euros	Notional amount for hedge on forecasted R&D and other operating expenses	Notional amount for hedge on forecasted manufacturing costs
Forward contracts	445	951

Cash flow and fair value interest rate risk

The Company’s interest rate risk arises from long-term borrowings. Borrowings issued at variable rates expose the Company to cash flow interest rate risk. Borrowings issued at fixed rates expose the Company to fair value interest rate risk.

The Company analyses its interest rate exposure on a dynamic basis. Various scenarios are simulated taking into consideration refinancing, renewal of existing positions, alternative financing and hedging. The Company invests primarily on a short-term basis and as such the Company’s liquidity is invested in floating interest rate

instruments. As a consequence, the Company is exposed to interest rate risk due to potential mismatch between the return on its short-term floating interest rate investments and the portion of its long-term debt issued at fixed rate.

Price risk

As part of its ongoing investing activities, the Company may invest in publicly traded equity securities and be exposed to equity security price risk. In order to hedge the exposure to this market risk, the Company may enter into certain derivative hedging transactions.

The Company entered into currency collars as combinations of two options, which are reported, for accounting purposes, on a net basis. As of December 31, 2023, the fair value of these collars represented assets for a net amount of $7 million (composed of $8 million assets offset with a $1 million liability). In addition, the Company entered into other derivative instruments, primarily forward contracts, which are governed by standard International Swaps and Derivatives Association (“ISDA”) agreements and are compliant with Protocols of the

European Market Infrastructure Regulation (“EMIR”), which are not offset in the statement of financial position and representing total assets of $53 million and liabilities of $4 million as of December 31, 2023.

The Company did not enter into any derivative containing significant credit-risk-related contingent features.

Credit risk

The expected credit loss and impairment methodology applied on each category of financial assets is further described in each respective note. While cash and cash equivalents are also subject to the expected credit loss model, the identified expected credit loss is deemed to be immaterial. The maximum credit risk exposure for all financial assets is their carrying amount.

Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. Credit risk typically arises from cash and cash equivalents, contractual cash flows of debt investments carried at amortized cost, the counterparty of derivative financial instruments and deposits with banks and financial institutions, as well as credit exposure to customers, including outstanding receivables.

The Company is exposed to credit risk from its operating activities (primarily for trade receivables) and from its financing activities, including deposits with banks and financial institutions, foreign exchange transactions and other financial instruments. Credit risk is managed at the Group level. The Company selects banks and/or financial institutions that operate with the group based on the criteria of long-term rating from at least two major Rating Agencies and keeping a maximum outstanding amount per instrument with each bank not to exceed 20% of the total. For derivative financial instruments, management has established limits so that, at any time, the fair value of contracts outstanding is not concentrated with any individual counterparty.

The Company monitors the creditworthiness of its customers to which it grants credit terms in the normal course of business. If certain customers are independently rated, these ratings are used. Otherwise, if there is no independent rating, risk control assesses the customer’s credit quality, considering its financial position, past experience and other factors. The utilization of credit limits is regularly monitored. Sales to customers are primarily settled in cash, which mitigates credit risk. As of December 31, 2023 and 2022, no customer represented more than 10% of trade accounts receivable, net. Any remaining concentrations of credit risk with respect to trade receivables are limited due to the large number of customers and their dispersion across many geographic areas.

The Company’s investments in instruments carried at amortized cost primarily include receivables towards government bodies. As such, they are investments with immaterial expected credit loss. Any remaining receivable is of low credit risk and is individually not significant. The credit ratings of the investments are monitored for credit deterioration.

Liquidity risk

Prudent liquidity risk management includes maintaining sufficient cash and cash equivalents, short-term deposits and marketable securities, the availability of funding from committed credit facilities and the ability to close out market positions. The Company’s objective is to maintain a significant cash position and a low debt-to-equity ratio, which ensures adequate financial flexibility. Liquidity management policy is to finance the Company’s investments with net cash from operating activities.

Management monitors rolling forecasts of the Company’s liquidity reserve based on expected cash flows.

26.2 Capital risk management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to create sustainable value, benefits and returns for its stakeholders, as to maintain an optimal capital structure. In order to maintain or adjust its capital structure, the Company may review the amount of dividends paid to shareholders, return capital to shareholders, or issue new shares.

Consistent with other peers in the industry, the Company monitors capital on the basis of the net debt-to-equity ratio. This ratio is calculated as the net financial position of the Company, defined as the difference between total cash position (cash and cash equivalents, short-term deposits, marketable securities and restricted cash, if any) and total financial debt (short-term and long-term debt), divided by total parent company stockholders’ equity.

26.3 Fair value measurement

The fair value of financial instruments traded in active markets is based on quoted market prices at the balance sheet date. The quoted market price used for financial assets held by the Company is the bid price. If the market for a financial asset is not active and if no observable market price is obtainable, the Company measures fair value by using significant assumptions and estimates. When measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

The table below details financial assets (liabilities) measured at fair value on a recurring basis as of December 31, 2023:


	Fair Value Measurements using

Amount of total gains (losses) for the period included in earnings attributable to liabilities still held at the reporting date						12

Contingent consideration reported as liabilities on the consolidated balance sheet as of December 31, 2023 and December 31, 2022 is based on the probability that the milestones defining the variable components of the

consideration will be achieved. In 2023, the probability of achievement of these variable components was reassessed, resulting in a reduction of $12 million of the fair value of the contingent consideration related to a certain business acquisition from 2020. The Company reported this change in fair value in the line “Research and development expenses” of the consolidated statement of income.

For liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3), the reconciliation between January 1, 2022 and December 31, 2022 is presented as follows:


						Fair Value Measurements using Significant Unobservable Inputs (Level 3)

No asset (liability) was measured at fair value on a non-recurring basis using significant unobservable inputs (Level 3) as of December 31, 2023 and December 31, 2022.

The Company evaluated in 2023, 2022 and 2021 for impairment the aggregate carrying amount of long-term investments for which the Company applies the cost method as a measurement alternative, as described in Note 2.22. No significant impairment charge was recorded on these investments in 2023, 2022 and 2021.

The following table includes additional fair value information on financial assets and liabilities as of December 31, 2023 and 2022:


	2023			2022
	Level	Carrying Amount	Estimated Fair Value	Carrying Amount	Estimated Fair Value
Cash equivalents (1)	1	2,879	2,879	2,996	2,996
Marketable securities	1	1,635	1,635	679	679

– Senior unsecured convertible bonds issued on August 4, 2020 (2)	1	1,496	1,814	1,495	1,561

(1) Cash equivalents primarily correspond to deposits at call with banks.

The methodologies used to estimate fair value are as follows:


Components			Methodology used to estimate fair value
Debt securities classified as available-for-sale			Quoted market prices for identical instruments
Foreign exchange forward contracts, currency options and collars			Quoted market prices for similar instruments
Equity securities measured at fair value through earnings			Quoted market prices for identical instruments
Equity securities carried at cost as a measurement alternative			Valuation of the underlying investments on a new round of third-party financing or upon liquidation
Long-term debt and current portion of long-term debt			Future cash flows on a borrowing-by-borrowing basis and discounting these future cash flows using the Company's incremental borrowing rates for similar types of borrowing arrangements. For convertible bonds, the fair value represents the market price of the bonds trading on the Frankfurt Stock Exchange
Cash and cash equivalents, short-term deposits, accounts receivable, short-term borrowings, and accounts payable			The carrying amounts reflected in the consolidated financial statements are considered as reasonable estimates of fair value due to the relatively short period of time between the origination of the instruments and their expected realization.

Equity [Abstract]

Shareholders' Equity

SHAREHOLDERS’ EQUITY

18.1 Outstanding shares

The authorized share capital of the Company is Euro 1,810 million, consisting of 1,200,000,000 common shares and 540,000,000 preference shares, each with a nominal value of €1.04. As of December 31, 2023, the number of shares of common stock issued was 911,281,920 shares (911,281,920 as of December 31, 2022).

As of December 31, 2023, the number of shares of common stock outstanding was 902,771,081, 903,865,763 as of December 31, 2022 and 906,518,057 as of December 31, 2021.

18.2 Preference shares

The 540,000,000 preference shares, when issued, will entitle a holder to full voting rights and to a preferential right to dividends and distributions upon liquidation.

The Company is a party to an option agreement regarding the preference shares with Stichting Continuïteit ST (the “Stichting”), entered into on January 22, 2007, with a duration of ten years, an agreement which was extended for another ten years in October 2016. The Managing Board and Supervisory Board, along with the board of the Stichting, have declared that they are jointly of the opinion that the Stichting is independent of the Company. The option agreement provides for the issuance of up to a maximum 540,000,000 preference shares. Any such shares would be issued to the Stichting upon its request and in its sole discretion and upon payment of at least 25% of the par value of the preference shares to be issued. The shares would be issuable in the event of actions which the board of the Stichting determines would be contrary to the Company’s interests, shareholders and other stakeholders and which, in the event of a creeping acquisition or offer for the Company’s common shares, are not supported by the Company’s Managing Board and Supervisory Board. The preference shares may remain outstanding for no longer than two years. The effect of the preference shares may be to deter potential acquirers from effecting an unsolicited acquisition resulting in a change of control as well as to create a level-playing field in the event actions which are considered to be hostile by the Company’s Managing Board and Supervisory Board, as described above, occur and which the board of the Stichting determines to be contrary to the Company’s interests, shareholders and other stakeholders.

There were no preference shares issued as of December 31, 2023 and December 31, 2022.

18.3 Treasury stock

As of December 31, 2023, the Company owned 8,510,839 shares classified as treasury stock in the consolidated statement of equity compared to 7,416,157 shares as of December 31, 2022 and 4,758,863 shares as of December 31, 2021.

The treasury shares have been originally designated for allocation under the Company’s share-based remuneration programs. As of December 31, 2023, 81,022,515 of these treasury shares were transferred to employees under the Company’s share-based remuneration programs, of which 6,502,300 during the year ended December 31, 2023, 6,587,002 shares during the year ended December 31, 2022 and 7,448,615 shares during the year ended December 31, 2021.

On July 1, 2021, the Company announced the launch of a share buy-back program of up to $1,040 million to be executed within a three-year period. During 2023, the Company purchased approximately 7.6 million shares of its outstanding common stock for $346 million as part of the program. The Company purchased approximately

9.2 million shares of its outstanding common stock for $346 million during 2022. The Company purchased approximately 3.9 million shares of its outstanding common stock for $172 million during 2021.

18.4 Unvested share awards for the Supervisory Board

On an annual basis and until the year 2012, the Compensation Committee (on behalf of the Supervisory Board and with its approval) used to grant stock-based awards (options to acquire common shares of the Company) to the members and professionals of the Supervisory Board (“The Supervisory Board Plan”). The awards were granted at the nominal value of the share of €1.04 (exercise price of the option). The options granted under the Supervisory Board Plan vested and became exercisable immediately, while the shares resulting from these awards vested and therefore became available for trade evenly over three years (one third every year), with no market, performance or service conditions.

At the Company’s AGM held on June 21, 2013, it was resolved to abolish and terminate the stock-based compensation for the Supervisory Board members and professionals.

The table below summarizes grants under the outstanding stock award plans, as authorized by the Compensation Committee:


Year of grant	Options granted	Options waived at grant

2011	172,500	(30,000)
2012	180,000	(22,500)
Since 2013	No options granted

A summary of the options’ activity by plan for the years ended December 31, 2023 and December 31, 2022 is presented below:


Year of grant	Outstanding as of December 31, 2021	Exercised	Expired / Cancelled	Outstanding as of December 31, 2022	Exercised	Expired / Cancelled	Outstanding as of December 31, 2023

2012	20,000	(5,000)	(15,000)	—	—	—	—

18.5 Unvested share awards for the employees

On an annual basis, the Compensation Committee (on behalf of the Supervisory Board and with its approval) grants stock-based awards to the senior executives and selected employees (the “Employee Plan”). The awards are granted for services rendered under the Employee Plan. There are two types of unvested shares: (1) shares granted to employees, which are subject only to service conditions and vest over the requisite service period, and (2) shares granted to senior executives, for which vesting is subject to performance conditions.

For plan 2020, the performance conditions consisted of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for two thirds of the total number of awards granted, and of one internal target (return on net assets compared to the previous period), weighting for one third of the total number of awards granted. For plans 2021, 2022 and 2023, the performance conditions consist of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for two thirds of the total number of awards granted, and of one internal target (Company’s sustainability and diversity performance), weighting for one third of the total number of awards granted. Sustainability and diversity performance include environment/climate, diversity and inclusions indicators, ESG investor index and carbon rating.

Stock awards are subject to three-year cliff-vesting for the Company's CEO, while they vest over a grading three-year service period for other employees (32% as of the first anniversary of the grant, 32% as of the second anniversary of the grant and 36% as of the third anniversary of the grant). Applicable only to the 2023 plan,

stock awards allocated to members of the Executive Committee are also subject to three-year cliff vesting. In addition, for the year 2020, a Special Bonus was granted to the Company’s CEO.

The table below summarizes grants outstanding during the year 2023, as authorized by the Compensation Committee:


Date of grant	Plan name	Number of shares granted	Number of shares waived	Number of shares lost on performance conditions
June 17, 2020	2020 CEO Special Bonus	16,000	—	—
July 23, 2020	2020 Employee Plan	7,437,580	—	—
December 24, 2020	2020 Employee Plan	562,350	—	—
July 28, 2021	2021 Employee Plan	6,327,205	—	(920,263)
December 21, 2021	2021 Employee Plan	213,270	—	(60,483)
July 27, 2022	2022 Employee Plan	6,243,670	—	—
December 22, 2022	2022 Employee Plan	287,675	—	—
July 26, 2023	2023 Employee Plan	5,154,115	—	(*)
December 11, 2023	2023 Employee Plan	295,020	—	(*)

(*) As of the date of issuance of these consolidated financial statements, a final decision by the Compensation Committee of the Supervisory Board on the achievement of the performance conditions had not been made yet.

A summary of the unvested share activity by plan for the year ended December 31, 2023 is presented below:


Unvested Shares	Unvested as at December 31, 2022	Granted	Forfeited / waived	Cancelled on failed vesting conditions	Vested	Unvested as at December 31, 2023
2020 CEO Special Bonus	5,334	—	—	—	(5,334)	—
2020 Employee Plan	2,780,796	—	(11,851)	—	(2,768,945)	—
2021 Employee Plan	3,699,514	—	(32,571)	—	(1,716,700)	1,950,243
2022 Employee Plan	6,496,525	—	(80,065)	—	(2,065,721)	4,350,739
2023 Employee Plan	—	5,449,135	(28,730)	—	—	5,420,405

Total	12,982,169	5,449,135	(153,217)	—	(6,556,700)	11,721,387

The grant date fair value of unvested shares granted to the CEO under the 2020 CEO Special Bonus Plan was $26.64, which was based on the market price of the shares at the date of the grant.

The grant date weighted average fair value of unvested shares granted to employees under the 2020 Employee Plan was $30.17. On March 24, 2021, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, all three performance conditions were fully met. Consequently, the compensation expense recorded on the 2020 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – 100% of the awards granted has fully vested, as far as the service condition was met.

The grant date weighted average fair value of unvested shares granted to employees under the 2021 Employee Plan was $39.20. On March 23, 2022, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, two performance conditions were fully met. Consequently, the compensation expense recorded on the 2021 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – two thirds of the awards granted will fully vest, as far as the service condition is met.

The grant date weighted average fair value of unvested shares granted to employees under the 2022 Employee Plan was $35.92. On March 22, 2023, the Compensation Committee approved the statement that with respect to

the shares subject to performance conditions, all three performance conditions were fully met. Consequently, the compensation expense recorded on the 2022 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – 100% of the awards granted will fully vest, as far as the service condition is met.

The grant date weighted average fair value of unvested shares granted to employees under the 2023 Employee Plan was $50.96. Moreover, for the portion of the shares subject to performance conditions (2,589,952 shares) the Company estimated the number of awards expected to vest by assessing the probability of achieving the performance conditions. As of the date of issuance of these consolidated financial statements, a final determination by the Compensation Committee of the Supervisory Board of the achievement of the performance conditions had not been made yet. The Company estimated that 100% of the awards subject to performance conditions are expected to vest. Consequently, the compensation expense recorded for the 2023 Employee Plan reflects the expected vesting of 100% of the awards granted with performance conditions, subject to the service condition being met. The assumption of the expected number of awards to be vested upon achievement of the performance conditions is subject to changes based on the final measurement of the conditions, which is expected to occur in the first half of 2024.

The following table illustrates the classification of pre-payroll tax and social contribution stock-based compensation expense included in the consolidated statements of income for the years ended December 31, 2023, 2022 and 2021:


	December 31, 2023	December 31, 2022	December 31, 2021

Cost of sales	40	34	34
R&D	71	69	70
SG&A	125	112	117
Total pre-payroll tax and social contribution compensation	236	215	221

The grant date fair value of the shares that vested in 2023 was $226 million compared to $189 million in 2022 and $181 million in 2021.

Stock-based compensation, excluding payroll tax and social contribution, capitalized as part of inventory was $13 million as of December 31, 2023, compared to $11 million as of December 31, 2022 and $9 million as of December 31, 2021. As of December 31, 2023, there was $265 million of total unrecognized compensation cost related to the grant of unvested shares, which is expected to be recognized over a weighted average period of approximately 10 months.

The total deferred income tax benefit recognized in the consolidated statements of income related to unvested share-based compensation expense amounted to $17 million, $15 million and $14 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Government Assistance [Abstract]
Public Funding	PUBLIC FUNDING The main government assistance received by the Company are classified under four general categories: funding for Research and Development (R&D), R&D and Innovation activities (RDI), funding for First Industrial Deployment activities (FID) and capital investments for pilot lines and other industrial activities. Receivables related to public funding totaled $861 million as of December 31, 2023, of which $651 million reported on the line “Other current assets” and $210 million reported on the line “Other non-current assets”, as collection is expected beyond 12 months. The receivables related to public funding included $378 million of capital grants associated with capital investments projects for the Company's 300mm wafer fab in Crolles, France and its silicon carbide manufacturing activities in Italy. These public funding programs also set forth a clawback mechanism according to which the public government agencies will require, at specific future testing dates, the remeasurement of the aid, which may trigger future payments by the Company. No provision was recorded as of December 31, 2023 in relation to this clawback mechanism. Receivables related to public funding amounted to $346 million, of which $190 million reported on the line “Other current assets” and $156 million reported on the line “Other non-current assets” of the consolidated balance sheet as of December 31, 2022. Research tax credit receivables totaled $246 million and were reported on the line “Other non-current assets” of the consolidated balance sheet as of December 31, 2023. Research tax credit receivables totaled $294 million and were reported on the line “Other non-current assets” of the consolidated balance sheet as of December, 31, 2022. In 2023, the Company and Sanan Optoelectronics jointly created SANAN, STMicroelectronics Co., Ltd. ("SST JV"), for high-volume 200mm SiC device manufacturing in China. SST JV has been identified as a VIE for which the Company is the primary beneficiary. As such, SST JV was fully consolidated as of December 31, 2023, as further described in Note 12. The newly incorporated entity is part of a capital funding scheme with regional government agencies. As of December 31, 2023, long-term liabilities related to public funding included $152 million advances from capital grants received as part of this funding program. Liabilities related to other public funding programs totaled $292 million as of December 31, 2023, of which $96 million reported on the line “Other payables and accrued liabilities” and $196 million reported on the line “Other long-term liabilities” of the consolidated balance sheet. Current liabilities related to public funding include $44 million grants subject to a financial return, which depended on future cumulative sales of a certain product group over a five-year period. As of December 31, 2022, liabilities related to public funding amounted to $88 million, of which, $37 million advances from grants reported in “Other payables and accrued liabilities” and $51 million reported on the line “Other long-term liabilities”. Additionally, $711 million and $95 million capital investment grants were reported as a reduction of Property, plant and equipment, net as of December 31, 2023 and December 31, 2022 respectively. Tax incentives reducing the carrying amount of Property, plant and equipment are further described in Note 10 and in Note 23. For the year ended December 31, 2023, the Company recorded $201 million of public funding related to R&D and innovation activities, reported on the line “Other income and expenses, net” of the consolidated statement of income compared to $177 million for the year ended December 31, 2022. The research tax credit received in France totaled $126 million and was reported as a reduction of “Research and development” in the consolidated statement of income for the year ended December 31, 2023 compared to $106 million for the year ended December 31, 2022. The Company reported as a reduction of cost of sales in the consolidated statement of income for the year ended December 31, 2023 a total $102 million amount related to FID funding programs compared to $59 million for the year ended December 31, 2022. The Company also benefits from research tax credits and other tax incentives to foster research and innovation activities, together with capital investments in certain tax jurisdictions, primarily in France and Italy. These research tax credits and tax incentive schemes are further described in Note 23. In addition, the impact on depreciation expense of tax incentives received in certain tax jurisdictions and reducing the carrying amount of “Property, plant and equipment, net”, are described in Note 10 and in Note 23.

TRADE ACCOUNTS RECEIVABLE, NET

Trade accounts receivable, net consist of the following:


	December 31,	December 31,
	2023	2022
Trade accounts receivable	1,750	1,991
Current expected credit losses allowance ("CECLA")	(19)	(21)
Total	1,731	1,970

The Company uses a lifetime expected losses allowance for all trade receivables based on failure rates, as applied to the gross amounts of trade accounts receivable. The allowance also includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of the Company’s customers to settle the receivables. In addition to the factors already embedded in the failure rates, as applied on trade accounts receivable, the Company has identified cyclicality and uncertainties around continued growth for the semiconductor industry and its serviceable available market to be the most relevant factors. These macro-economic factors are weighted into different economic scenarios, in line with estimates and methodologies applied by other business entities, including financial institutions.

On that basis, the changes in reported CECLA for the year ended December 31, 2023 are presented below:


CECLA As of December 31, 2022						(21)
Current-period adjustment to CECLA						2
CECLA As of December 31, 2023						(19)

Adjustments to the expected credit losses allowance are reported in the line “Selling, general and administrative expenses” in the consolidated statements of income.

There were no significant write-offs in 2023, 2022 and 2021.

Long-term investments	22	11
Total	22	11

Long-term investments are equity securities with no readily determinable fair value for which the Company has elected to apply the cost method as a measurement alternative. Long-term investments include a $9 million interest in DNP Photomask Europe S.p.A (“DNP”). In 2023, the Company paid $10 million to acquire a minor

equity stake in a start up. The investment is related to the development of Silicon Photonics technology for the RF Communications business.

In 2023, the Company and Sanan Optoelectronics jointly created SANAN, STMicroelectronics Co., Ltd. for high-volume 200mm SiC device manufacturing activities in China. The purpose of the joint venture is to support the rising demand for the Company's SiC devices for car electrification and industrial power and energy applications in China. With the creation and future operations of SST JV, the Company seeks to create a fully integrated vertical value chain aiming at serving the Chinese electrification market. Sanan Optoelectronics will build a separate 200mm SiC substrate manufacturing facility to fulfill SST JV's needs. SST JV will produce SiC devices exclusively for the Company, using the Company's proprietary SiC manufacturing process technology and know how and serving as a dedicated foundry to support the Company's demand for Chinese customers.

The Company has identified SST JV as a VIE, primarily based on the disproportionality between its 49% equity interest rights and its economic interest and operating role in the joint venture. Indeed the significant activities of SST JV involve or are conducted on behalf of the Company as the sole customer of the joint venture. Moreover, through its key role in the successful process qualification and future manufacturing efficiency based on its SiC manufacturing process technology, the Company has the power to control the activities that most significantly impact SST JV's future economic performance. Additionally, based on the nature of the risks impacting SST JV's future economic performance, the Company will absorb the potential losses of SST JV or the right to receive benefits downstream the whole integrated SiC device value chain. Consequently, the Company has a controlling financing interest in SST JV and is the primary beneficiary of the VIE.

As the primary beneficiary of SST JV, the Company fully consolidates the VIE, with the recognition of 51% non-controlling interest. Non-controlling interest amounted to $52 million as of December 31, 2023, which corresponds to the capital contribution received from Sanan Optoelectronics upon creation and first consolidation of SST JV. No gain or loss was recognized on the initial consolidation of the VIE as no fair value measurement was required, the joint venture being a newly incorporated entity. Profit and loss reported by the VIE for the year ended December 31, 2023 was not material. The carrying amount of SST JV's assets and liabilities, together with their classification in the consolidated balance sheet as of December 31, 2023, are separately disclosed in Note 7, Note 10 and Note 17.

The joint venture agreement signed between Sanan Optoelectronics and the Company includes further capital subscriptions of both shareholders on a proportional equity interest basis. The total amount for the full build out of the joint venture will also be financed by local government support, as disclosed in Note 7, and loans to the joint venture.

The Company receives public funding from governmental bodies in several jurisdictions. Public funding is further described in Note 7.

Start-up costs represent costs incurred in the ramp-up phase of the Company’s newly integrated manufacturing facilities, primarily for the new 300mm fab in Agrate, Italy. Phase-out costs are costs incurred during the closing stage of a Company’s manufacturing facility.

Exchange gains and losses, net represent the portion of exchange rate changes on transactions denominated in currencies other than a subsidiary’s functional currency and the changes in fair value of derivative instruments which are not designated as hedges, as described in Note 26.

Patent costs mainly include legal and attorney fees and payment for claims, patent pre-litigation consultancy and legal fees. They are reported net of settlements, if any, which primarily include reimbursements of prior patent litigation costs.

COVID-19 incremental costs were mainly composed of incremental expenses primarily related to sanitary measures undertaken to protect employees. Starting January 1, 2023, the Company no longer reports Covid-19 related expenses as a component of the line “Other income and expenses, net” in the consolidated statement of income.

Contingencies, Claims and Legal Proceedings	Dec. 31, 2023
Commitments and Contingencies Disclosure [Abstract]
Contingencies, Claims and Legal Proceedings	COMMITMENTS, CONTINGENCIES, CLAIMS AND LEGAL PROCEEDINGS The Company's commitments relate to multi-annual agreements with suppliers when there is a fixed, non-cancelable commitment or when minimum payments are due on a committed delivery schedule. These commitments are primarily comprised of purchase commitments for outsourced foundry wafers ($1.1 billion) and firm contractual commitments related to power purchase and minimum energy efficiency, as part of the Company's actions to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3 ($0.8 billion). The Company is subject to possible loss contingencies arising in the ordinary course of business. These include but are not limited to: product liability claims and/or warranty cost on the products of the Company, contractual disputes, indemnification claims, claims for unauthorized use of third-party intellectual property, employee grievances, tax claims beyond assessed uncertain tax positions as well as claims for environmental damages. In determining loss contingencies, the Company considers the likelihood of impairing an asset or the incurrence of a liability at the date of the consolidated financial statements as well as the ability to reasonably estimate the amount of such loss. The Company records a provision for a loss contingency when information available before the consolidated financial statements are issued or are available to be issued indicates that it is probable that an asset has been impaired or a liability has been incurred at the date of the consolidated financial statements and when the amount of loss can be reasonably estimated. The Company regularly re-evaluates claims to determine whether provisions need to be readjusted based on the most current information available to the Company. Changes in these evaluations could result in an adverse material impact on the Company’s results of operations, cash flows or its financial position for the period in which they occur. The Company has received and may in the future receive communications alleging possible infringements of third-party patents or other third-party intellectual property rights. Furthermore, the Company from time to time enters into discussions regarding a broad patent cross license arrangement with other industry participants. There is no assurance that such discussions may be brought to a successful conclusion and result in the intended agreement. The Company may become involved in costly litigation brought against the Company regarding patents, mask works, copyrights, trademarks or trade secrets. In the event that the outcome of any litigation would be unfavorable to the Company, the Company may be required to take a license to third-party patents and/or other intellectual property rights at economically unfavorable terms and conditions, and possibly pay damages for prior use and/or face an injunction, all of which individually or in the aggregate could have a material adverse effect on the Company’s results of operations, cash flows, financial position and/or ability to compete. On December 4, 2023, a jury in the United States District Court for the Western District of Texas in Waco, Texas (USA) returned a verdict in a patent infringement lawsuit in favor of the plaintiff, Purdue University. The Court has not issued final judgment. If the Court issues a final judgment in the plaintiff’s favor, the Company will file post-trial motions and, if they are denied, the Company will file an appeal to the United States Court of Appeals for the Federal Circuit in Washington DC. The risk on this case is considered as possible and, based on the jury verdict, the possible loss is estimated at $32 million. The Company has contractual commitments to various customers which could require the Company to incur costs to repair or replace defective products it supplies to such customer. The duration of these contractual commitments varies and, in certain cases, is indefinite. The Company is otherwise also involved in various lawsuits, claims, inquiries, inspections, investigations and/or proceedings incidental to its business and operations. Such matters, even if not meritorious, could result in the expenditure of significant financial or managerial resources. Any of the foregoing could have a material adverse effect on the Company’s results of operations, cash flows or its financial position. The Company regularly evaluates claims and legal proceedings together with their related probable losses to determine whether they need to be adjusted based on the current information available to the Company. There can be no assurance that its recorded reserves will be sufficient to cover the extent of its potential liabilities. Legal costs associated with claims are expensed as incurred. In the event of litigation which is adversely determined with respect to the Company’s interests, or in the event the Company needs to change its evaluation of a potential third-party claim, based on new evidence or communications, a material adverse effect could impact its operations or financial condition at the time it were to materialize. As of December 31, 2023 and 2022, respectively, provisions for estimated probable losses with respect to claims and legal proceedings were not considered material.

Interest income is related to cash and cash equivalents, short-term deposits and marketable securities held by the Company.

Interest income, net recorded in 2023 was composed of $226 million of interest income, partially offset by interest expense on borrowings and banking fees of $55 million.

Interest expense included the financial cost of the convertible bonds issued by the Company in 2020. On January 1, 2022, the Company adopted the new U.S. GAAP reporting guidance on distinguishing liabilities from equity and EPS. The new guidance was adopted by applying the modified retrospective method, under which prior year periods are not restated. Interest expense recorded in 2021 included a charge of $34 million related to the outstanding senior unsecured convertible bonds, mainly resulting from the non-cash accretion expense, as recorded under the previous accounting guidance. With the adoption of the new guidance, the finance cost of the convertible debt instruments outstanding at the date of adoption is limited to the amortization expense of debt issuance costs. The amortization expense of debt issuance costs amounted to $1 million for the year ended December 31, 2023, $1 million for the year ended December 31, 2022 and $3 million for the year ended December 31, 2021.

No borrowing cost was capitalized in 2023, 2022 and 2021. Nominal interest income received in cash on U.S. Treasury Bonds classified as available-for-sale marketable securities amounted to $15 million for the year ended December 31, 2023, $1 million for the year ended December 31, 2022 and $1 million for the year ended December 31, 2021.

Retirement Benefits [Abstract]

Post-Employment and Other Long-Term Employees Benefits

POST-EMPLOYMENT AND OTHER LONG-TERM EMPLOYEES BENEFITS

The Company and its subsidiaries have a number of defined benefit pension plans, mainly unfunded, and other long-term employees’ benefits covering employees in various countries. The defined benefit plans provide pension benefits based on years of service and employee compensation levels. The other long-term employees’ plans provide benefits due during the employees’ period of service after certain seniority levels. The Company uses December 31 as measurement date for its plans. Eligibility is generally determined in accordance with local statutory requirements. For Italian termination indemnity plan (“TFR”), generated before July 1, 2007, the Company measures the vested benefits to which Italian employees are entitled as if the amounts were immediately due as of December 31, 2023, in compliance with U.S. GAAP guidance on determining vested benefit obligations for defined benefit pension plans.

The changes in benefit obligation and plan assets were as follows:


	Pension Benefits		Other Long-Term Benefits
	December 31, 2023	December 31, 2022	December 31, 2023	December 31, 2022

Net amount recorded	(354)	(319)	(99)	(86)

The actuarial losses incurred in 2023 were primarily due to a decrease in discount rates applied against future expected benefit payments and resulted in an increase of the benefit obligation mainly for the plans located in the United States, France and Switzerland. The actuarial gains incurred in 2022 were primarily due to an increase in discount rates applied against future expected benefit payments and resulted in a decrease of the benefit obligation mainly for the plans located in France, in the United States and Switzerland.

Actual return on plan assets reflect changes in market conditions during each reporting year.

The components of accumulated other comprehensive loss (income) before tax effects were as follows:


	Actuarial (gains)/losses	Prior service cost	Total
Accumulated other comprehensive loss as of December 31, 2021	142	2	144

For pension plans and other long-term benefits with accumulated benefit obligations in excess of plan assets, the accumulated benefit obligation and fair value of plan assets were $411 million and $182 million, respectively, as of December 31, 2023 and $409 million and $139 million, respectively, as of December 31, 2022.

For pension plans with projected benefit obligations in excess of plan assets, the benefit obligation and fair value of plan assets were $950 million and $478 million, respectively, as of December 31, 2023 and $839 million and $427 million, respectively, as of December 31, 2022.

The components of the net periodic benefit cost included the following:


	Pension Benefits			Other Long-term Benefits
	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021

Net periodic benefit cost	47	44	46	18	4	14

Pension benefits components other than service cost, recognized outside of operating income in “Other components of pension benefit costs” in the Company’s consolidated statements of income, were $19 million, $11 million and $10 million in the years ended December 31, 2023, 2022 and 2021, respectively.

The weighted average assumptions used to determine the benefit obligation and the periodic benefit costs for pension plans and other long-term benefits were as follows:


	2023		2022		2021
Benefit obligation
Discount rate	3.73	%	4.18	%	1.84	%
Salary increase rate	2.17	%	2.31	%	2.27	%
Net periodic benefit cost
Discount rate	4.18	%	1.84	%	1.45	%
Salary increase rate	2.31	%	2.27	%	2.43	%
Expected long-term rates of return on plan assets	2.66	%	3.19	%	3.44	%

The discount rate was determined by reference to market yields on high quality long-term corporate bonds applicable to the respective country of each plan, with terms consistent with the terms of the benefit obligations. In developing the expected long-term rate of return on assets, the Company modelled the expected long-term rates of return for broad categories of investments held by the plan against a number of various potential economic scenarios.

The Company’s pension plan asset allocation as of December 31, 2023 and December 31, 2022 is as follows:


	Percentage of Plan Assets at December
Asset Category	2023		2022
Cash and cash equivalents	1	%	1	%
Equity securities	13	%	17	%
Government debt securities	11	%	10	%
Corporate debt securities	19	%	21	%
Investments in funds(a)	15	%	16	%
Real estate	1	%	1	%
Other (mainly insurance assets – contracts and reserves)	40	%	34	%
Total	100	%	100	%

As of December 31, 2023, the Company’s plan asset allocation was in line with the targets set for each plan.

The Company’s detailed pension plan asset allocation including the fair-value measurements of those plan assets as of December 31, 2023 is as follows:


	Total	Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)

The majority of insurance contract plan assets relate to pension plans for the Company's employees in Switzerland. Those plans are provided by collective pension foundations and contributions are invested in fully insured assets that provide a guaranteed contractual return. As such, the fair value of such assets equals to the employees' accrued savings and calculated using total employer and employee contributions plus any accumulated interest credited, which is substantially equivalent to the related cash surrender value. The approach is consistent with prior years.

For plan assets measured at fair value using significant unobservable inputs (Level 3), the reconciliation between January 1, 2023 and December 31, 2023 is presented as follows:


						Fair Value Measurements using Significant Unobservable Inputs (Level 3)
January 1, 2023						178
Contributions (employer and employee)						21
Actual return on plan assets (b)						4
Net benefit payments (a)						14
Settlements (b)						(1)

Foreign currency translation adjustment (c)						17
December 31, 2023						233

(a) Net cash flows between benefits paid from the insurance contracts and benefits transferred into the insurance contracts by employees.

(b) Included in non operating expenses in the consolidated statement of income.

For plan assets measured at fair value using significant unobservable inputs (Level 3), the reconciliation between January 1, 2022 and December 31, 2022 is presented as follows:


						Fair Value Measurements using Significant Unobservable Inputs (Level 3)
January 1, 2022						167
Contributions (employer and employee)						21

Net benefit payments (a)						9
Settlements						(14)

Foreign currency translation adjustment						(5)
December 31, 2022						178

(a) Net cash flows between benefits paid from the insurance contracts and benefits transferred into the insurance contracts by employees.

The Company’s investment strategy for its pension plans is to optimize the long-term investment return on plan assets in relation to the liability structure to maintain an acceptable level of risk while minimizing the cost of providing pension benefits and maintaining adequate funding levels in accordance with applicable rules in each jurisdiction. The Company’s practice is to periodically conduct a review of its asset allocation strategy, in such a way that the asset allocation is in line with the targeted asset allocation within reasonable boundaries. The

Company’s asset portfolios are managed in such a way as to achieve appropriate diversification in line with the asset allocation strategy. The Company does not manage any assets internally.

After considering the funded status of the Company’s defined benefit plans, movements in the discount rate, investment performance and related tax consequences, the Company may choose to make contributions to its pension plans in any given year in excess of required amounts. The Company’s contributions to plan assets were $26 million in 2023 and $25 million in 2022 and the Company expects to contribute $27 million to plan assets in 2024.

The Company’s estimated future benefit payments as of December 31, 2023 are as follows:


Years	Pension Benefits	Other Long-term Benefits
2024	59	7
2025	63	8
2026	86	8
2027	54	9
2028	60	8
From 2029 to 2033	375	44

The Company has certain defined contribution plans, which accrue benefits for employees on a pro-rata basis during their employment period based on their individual salaries. The Company’s accrued benefits related to defined contribution pension plans for $27 million as of December 31, 2023 and $24 million as of December 31, 2022. The annual cost of these plans amounted to approximately $114 million in 2023, $100 million in 2022 and $101 million in 2021.

* Other Comprehensive Income

In 2023, the Company invested $1,653 million available cash in U.S. Treasury bonds. The debt securities have an average rating of Aaa/AA+/AA+ from Moody’s, S&P and Fitch, respectively, with a weighted average maturity of 1.6 years. The debt securities are reported as current assets on the line “Marketable securities” on the consolidated balance sheet, since they represent investments of funds available for current operations. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of the amortized cost basis. The bonds are classified as available-for-sale financial assets and recorded at fair value as of December 31, 2023. The fair value measurement corresponds to a Level 1 fair value hierarchy measurement. The aggregate amortized cost basis of these securities totaled $1,645 million as of December 31, 2023.

Marketable securities totaling $750 million at principal amount were transferred to financial institutions as part of short-term securities lending transactions, in compliance with corporate policies. The Company, acting as the securities lender, does not hold any collateral in this unsecured securities lending transaction. The Company retains effective control on the transferred securities.

As of December 31, 2022, the Company held $679 million in marketable securities classified as available-for-sale debt securities.

The below table details debt securities that were in an unrealized loss position as of December 31, 2023:


	December 31, 2023

Public funding receivables, including French research tax credit receivable, are described in Note 7.

Prepayments and deposits to third parties include receivables related to long-term supply agreements involving purchase of raw materials, capacity commitments, cloud-hosting arrangements, and other services.

In 2023 and 2022, the Company entered into factoring transactions to accelerate the realization in cash of certain long-term receivables. The Company sold without recourse $118 million and $110 million of these receivables in the years ended December 31, 2023 and 2022 respectively, with a financial cost of $5 million and $1 million respectively.

The major portion of other non-current assets to which the expected credit loss model applies are long-term State receivables. Due to the existing history of zero-default on receivables originated by governments, the expected credit losses are assumed to be negligible as of December 31, 2023 and December 31, 2022. Other non-current assets presented in the table above on the line “Other non-current assets” are composed of individually not significant amounts not deemed to have exposure of default. Consequently, no significant expected credit loss allowance was reported on other non-current assets at reporting date.

EARNINGS PER SHARE

For the years ended December 31, 2023, 2022 and 2021, earnings per share (“EPS”) was calculated as follows:


	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021
Basic EPS
Net income attributable to parent company as reported	4,211	3,960	2,000

Number of shares used in calculating diluted EPS	944,197,767	946,221,547	924,842,198
Diluted EPS	4.46	4.19	2.16

On January 1, 2022, the Company adopted the new guidance on distinguishing liabilities from equity and EPS by applying the modified retrospective method, under which prior year periods are not restated.

Under the previous guidance, the Company applied the treasury stock method to determine the dilutive effect of convertible bonds as past experience, existing stated policies, and the contractual terms of the bonds provided a reasonable basis to expect that the settlement would include cash, shares, or a mix of both.

With the adoption of the new guidance, the treasury stock method is no longer admitted and the application of the if-converted method is mandatory to determine the dilutive effect of convertible bonds. The senior unsecured convertible bonds issued on August 4, 2020 are consequently fully dilutive, with the total underlying shares presented in the line “Dilutive effect of convertible bonds” of the table above for the years ended December 31, 2023 and December 31, 2022.

Income Tax Disclosure [Abstract]

Income Tax

INCOME TAX

Income (loss) before income tax is comprised of the following:


	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021
Income (loss) recorded in the Netherlands	(32)	(22)	(20)
Income (loss) from foreign operations	4,795	4,508	2,357
Income (loss) before income tax benefit (expense)	4,763	4,486	2,337

STMicroelectronics N.V. and its subsidiaries are individually liable for income taxes in their jurisdictions.

Income tax benefit (expense) is comprised of the following:


	Year ended December 31, 2023		Year ended December 31, 2022		Year ended December 31, 2021
The Netherlands taxes - current	—		—		—

Earnings of subsidiaries taxed at different rates	433	443	187
Income tax benefit (expense)	(541)	(520)	(331)

In 2022, the variation on the valuation allowance was related to the assessment of the recoverability of the deferred tax assets following the improved stability of profits of the Company in various jurisdictions.

The variation in the line "Effect of changes in tax laws and similar" in 2023 mainly relates to the recognition of a net deferred tax asset of $52 million related to a tax credit granted for technological activities, as well as the impact of the conclusion in 2023 of tax authority discussions resulting in the recognition of a net deferred tax asset of $81 million for intangibles recognized for tax purposes. These will be amortized over time and result in a future cash tax benefit.

The tax holidays represent a tax exemption period aimed to attract foreign technological investment in certain tax jurisdictions. The effect of the tax benefits, from tax holidays for countries which are profitable, on basic earnings per share was $0.05, $0.07 and $0.05 for the years ended December 31, 2023, 2022 and 2021, respectively. These agreements are present in various countries and include programs that reduce up to and including 100% of taxes in years affected by the agreements. The Company’s tax holidays expire at various dates through the year ending December 31, 2029. In certain countries, tax holidays can be renewed depending on the Company still meeting certain conditions at the date of expiration of the current tax holidays.

Component of the Net Deferred Tax Asset and Liability

Deferred tax assets and liabilities consisted of the following:


	December 31, 2023	December 31, 2022
Tax loss carryforwards, tax credits and other tax attributes	886	520
Less unrecognized tax benefits	(21)	(25)
Tax loss carryforwards, tax credits and other tax attributes, net of unrecognized tax benefits	865	495
Inventory valuation	48	42
Fixed asset depreciation	61	55
Increased depreciation incentives	48	83
Capitalized development costs	38	79
Receivables for government funding	152	121
Tax credits granted on capital investments	226	218
Pension	67	62
Stock awards	17	17
Operating lease liabilities	69	50
Commercial accruals	38	27
Other temporary differences	33	27
Total deferred tax assets	1,662	1,276
Valuation allowances	(782)	(416)
Deferred tax assets, net	880	860
Accelerated fixed asset depreciation	(40)	(37)
Acquired intangible assets	(24)	(23)
Advances of government funding	(185)	(177)
Operating lease right-of-use assets	(62)	(50)
Other temporary differences	(31)	(31)
Deferred tax liabilities	(342)	(318)
Net deferred income tax asset	538	542

For a particular tax-paying component of the Company and within a particular tax jurisdiction, all deferred tax liabilities and assets are offset and presented as a single amount in the balance sheet. The Company does not offset deferred tax liabilities and assets attributable to different tax-paying components or to different tax jurisdictions. The above table presents the deferred tax assets and liabilities before offset.

The variations in the lines "Tax losses carried forward, tax credits and other tax attributes" and "Valuation allowances” mainly include the recognition of deferred tax assets for a tax credit related to technological activities and the impact of the conclusion of discussions with the tax authorities for intangibles recognized for tax purposes, totaling $479 million decreased by $126 million related to the utilization of the tax losses in several jurisdictions following management’s assessment of the likelihood of future realization of the gross DTA recognized in the period.

The “Tax credits granted on capital investments” is mainly related to a 2003 agreement granting the Company certain tax credits for capital investments purchased through the year ending December 31, 2006. Any unused tax credits granted under the agreement will be impacted yearly by a legal inflationary index (currently 3.64% per annum). The credits may be utilized depending on the Company meeting certain program criteria and have no expiration date. In addition to this agreement, starting from 2007 the Company continues to receive tax credits on the yearly capital investments, which may be used to offset that year’s tax liabilities and increases by the legal inflationary rate. However, pursuant to the inability to utilize these credits currently and in future years,

the Company did not recognize any deferred tax asset on such tax allowance. As a result, there is no financial impact to the net deferred tax assets of the Company.

Deferred tax asset expiration

As of December 31, 2023, the Company and its subsidiaries have gross deferred tax assets on tax loss carryforwards, tax credits and other tax attributes that expire starting from 2024.


						December 31,
Year						2023
2024						3
2025						2
2026						2
2027						4
2028						3
Thereafter						872
Total						886

The amount reported on the line “Thereafter” includes tax attributes that expire in 2029 for $276 million and tax credit which will expire in 2030 for $203 million. The majority of the remaining amount has no expiration date.

Deferred Tax expense recognized through Other Comprehensive Income

In 2023, the Company recognized a deferred tax expense of $4 million as a component of other comprehensive income (loss), compared to a deferred tax expense of $26 million in 2022. They were related primarily to the tax effects of the recognized unfunded status on defined benefits plan.

Deferred tax on undistributed Earnings from foreign subsidiaries

The cumulative amount of distributable earnings related to the Company’s investments in foreign subsidiaries and corporate joint ventures was $7,575 million and $7,140 million as of December 31, 2023 and December 31, 2022, respectively. Due to the Company’s legal and tax structure, with the parent company established in the Netherlands, there is no significant tax impact from the distribution of earnings for $6,965 million from investments in foreign subsidiaries and corporate joint ventures. This is because there is no tax impact on dividends paid up to a Dutch holding company by qualifying investments. The amount of distributable earnings becoming taxable upon repatriation amount to $607 million. An amount of $387 million is indefinitely reinvested by the foreign subsidiaries. As of December 31, 2023, a deferred tax liability is recognized for $22 million on the amount of earnings expected to be repatriated in a foreseeable future.

Unrecognized Tax Benefits

A reconciliation of 2023, 2022 and 2021 beginning and ending amounts of unrecognized tax benefits is as follows:


	December 31, 2023	December 31, 2022	December 31, 2021
Balance at beginning of year	61	118	48
Additions based on tax positions related to the current year	—	4	72
Additions based on acquisitions related to the current year	—	—	—
Additions for tax positions of prior years	11	13	1
Reduction for tax positions of prior years	—	(69)	(1)
Settlements	(14)	(2)	—

Reductions due to lapse of statute of limitations	(4)	—	—
Foreign currency translation	1	(3)	(2)
Balance at end of year	55	61	118

In addition, as of December 31, 2023, $21 million of unrecognized tax benefits were classified as a reduction of deferred tax assets (as of December 31, 2022, the amount was $25 million). It is reasonably possible that certain of the uncertain tax positions disclosed in the table above could increase or decrease within the next 12 months due to ongoing tax audits. The Company is not able to make an estimate of the range of the reasonably possible change impacting the annual effective tax rate.

Additionally, the Company elected to classify accrued interest and penalties related to uncertain tax positions as components of income tax expense in the consolidated statements of income. They were less than $1 million in 2023, less than $1 million in 2022 and $1 million in 2021. Accrued interest and penalties amounted to $6 million as of December 31, 2023 and $6 million as of December 31, 2022.

The tax years that remain open for review from the tax authorities in the Company’s major tax jurisdictions are from 1997 to 2023.

Pillar II income taxes

Pillar II legislation has been enacted in certain jurisdiction the Company operates (Netherlands, the majority of the European Countries and Switzerland). The legislation will be effective for the Company's financial year beginning January 1, 2024. The Company is in the scope and has performed a preliminary assessment of the potential exposure of the Pillar II incomes taxes.

The assessment of the potential exposure to Pillar II income taxes is based on the most recent tax filings, 2022 country-by-country reporting and financial statements for the constituent entities in the Company. Based on the assessment, the Pillar II effective tax rates in most of the jurisdictions are above 15%. However, there is a limited number of jurisdictions where the transitional safe harbour relief does not apply and the Pillar II effective tax rate is slightly below 15%. Therefore, the Company expects a limited tax exposure to Pillar II income taxes in those jurisdictions. Pillar II income taxes impact will depend on the level of 2024 operating results within those jurisdictions as well as potential enactment of the Pillar II legislation or change in tax laws in those jurisdictions.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
