Accounting Policies [Abstract]
Accounting Policies	2. 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 period-end 2.1 – Principles of consolidation The Company’s consolidated financial statements include the assets, liabilities, results of operations and cash flows of its majority-owned subsidiaries. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases. Intercompany balances and transactions have been eliminated in consolidation. 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. Assets, liabilities, and the noncontrolling interest of newly consolidated VIEs are initially measured at fair value in the same manner as if the consolidation resulted from a business combination. 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 is reported on the line “Noncontrolling interest” in 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 returns and allowances, • 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 or sold, including intangibles, goodwill, investments and tangible assets, • annual and trigger-based impairment review of goodwill and intangible assets, as well as the assessment, in each reporting period, of events, which could trigger impairment testing on long-lived assets, • estimated value of the consideration to be received and used as fair value for asset groups classified as assets held for sale and the assessment of probability of realizing the sale, • assessment of other-than-temporary impairment charges on financial assets, including equity-method investments, • recognition and measurement of restructuring charges and other related exit costs, • assumptions used in assessing the number of awards expected to vest on stock-based compensation plans, • assumptions used in calculating pension obligations and other long-term employee benefits, and • determination of the amount of taxes 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 largely incurred in the countries of the Euro zone and other non-U.S. 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 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 at the closing exchange rate as of the balance sheet date; (b) income and expenses for each consolidated statement of income presented are translated at the average monthly exchange rate; (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 includes cash on hand, deposits held at call with external financial institutions and other short-term highly liquid investments with original maturities to the Company 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. Bank overdrafts are not netted against cash and cash equivalents and are shown as part of current liabilities on 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. They are reported net of allowances for doubtful accounts. The Company maintains an allowance for doubtful accounts for potential estimated losses resulting from its customers’ inability to make required payments. The Company bases its estimates on historical collection trends and records an allowance accordingly. Additionally, the Company evaluates its customers’ financial condition periodically and records an allowance for any specific account it considers as doubtful. The carrying amount of the receivable is thus reduced through the use of an allowance account, and the amount of the charge is recognized on the line “Selling, general and administrative” in the consolidated statements of income. Subsequent recoveries, if any, of amounts previously provided for are credited against the same line in the consolidated statements of income. When a trade accounts receivable is uncollectible, it is written-off 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 or market value. Cost is based on the weighted average cost by adjusting standard cost to approximate actual manufacturing costs on a quarterly basis; the cost is therefore dependent on the Company’s manufacturing performance. In the case of underutilization of manufacturing facilities, the costs associated with the unused capacity are not included in the valuation of inventories but charged directly to cost of sales. Market value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses and cost of completion. The Company performs, on a continuous basis, inventory write-offs of products, which have the characteristics of slow-moving, old production date and technical obsolescence. Indeed, the Company evaluates its product inventory to identify obsolete or slow-selling items and records a specific reserve if the Company estimates the inventory will eventually become obsolete. Reserve for obsolescence is estimated for excess uncommitted inventory based on the previous quarter sales, order backlog and production plans. 2.7 – Income taxes Income tax for the period comprises current and deferred income tax. Current income tax represents the income tax expected to be paid or the tax benefit expected to be received related to the current year taxable profit and loss in each tax jurisdiction. Deferred income tax is recognized, using the liability method, for all temporary differences arising between the tax bases of assets and liabilities and their carrying amount in the consolidated financial statements. However, deferred income tax is not accounted for if it arises from the initial recognition of an asset or liability in a transaction other than a business combination that, at the time of the transaction, affects neither accounting nor taxable profit and loss. Moreover, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. 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 benefit (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 the 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 impact the deferred tax asset and do not result in any adjustments prior to vesting. When the actual tax deduction is determined, generally upon vesting, it is compared to the deferred tax asset as recognized over the vesting period. When a windfall tax benefit is determined (as the excess tax benefit of the actual tax deduction over the deferred tax asset) the excess tax benefit is recorded in equity on the line “Capital surplus” on the consolidated statements of equity. In case of shortfall, only the actual tax benefit is to be recognized in the consolidated financial statements. The Company writes off the deferred tax asset at the level of the actual tax deduction by charging first capital surplus to the extent of the pool of windfall benefits available from prior years, and then in the consolidated statements of income on the line “Income tax benefit (expense)”. When the settlement of an award results in a net operating loss (“NOL”) carryforward, or increase of existing NOLs, the excess tax benefit and the corresponding credit to capital surplus is not recorded until the deduction reduces income tax payable. At each reporting date, the Company assesses all material open income tax positions in all tax jurisdictions to determine any uncertain tax positions. The Company uses a two-step more-likely-than-not 2.8 – Assets held for sale Asset groups are classified as assets held for sale when their carrying amount is to be recovered principally through a sale transaction rather than through continuing use. The asset groups are classified as assets held for sale when the following conditions have been met: management has approved the plan to sell; assets are available for immediate sale; assets are actively being marketed; sale is probable within one year; price is reasonable in the market and it is unlikely that there will be significant changes in the assets to be sold or a withdrawal to the plan to sell. Asset groups classified as held for sale are reported as current assets in the consolidated balance sheets at the lower of their carrying amount and fair value less costs to sell. Long-lived assets classified as held for sale are no longer depreciated. When the held-for-sale 2.9 – Business combinations and goodwill The purchase accounting method is applied to all business combinations. The identifiable assets acquired, equity instruments issued, and liabilities assumed are measured at fair value on the acquisition date. Any contingent purchase price and acquired contingencies are recorded at fair value on the acquisition date and at each reporting date. Acquisition-related transaction costs and restructuring costs relating to the acquired business are expensed as incurred. Acquired in-process Goodwill represents the excess of the aggregate of the consideration transferred and the fair value of any noncontrolling interest in the acquiree over the net of the acquisition-date amount of the identifiable assets acquired and liabilities assumed. Goodwill is carried at cost less accumulated impairment losses. Goodwill is not amortized but is tested annually for impairment, or more frequently if indicators of impairment exist. Goodwill subject to potential impairment is tested at a reporting unit level. The impairment test determines whether the fair value of each reporting unit for which goodwill is allocated is lower than the total carrying amount of relevant net assets allocated to such reporting unit, including its allocated goodwill. If lower, the implied fair value of the reporting unit goodwill is then compared to the carrying value of the goodwill and an impairment charge is recognized for any excess. 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. 2.10 – Intangible assets with finite useful lives Intangible assets subject to amortization include the intangible assets purchased from third parties recorded at cost and intangible assets acquired in business combinations recorded at fair value. Amortization begins when the intangible asset is available for use and is calculated using the straight-line method to allocate the cost of the intangible assets over their estimated useful lives. The carrying value of intangible assets with finite useful lives is evaluated whenever changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized in the consolidated statements of income on the line “Impairment, restructuring charges and other related closure costs” 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. Trademarks, technologies and licenses Separately acquired trademarks and licenses are recorded at historical cost. Trademarks and licenses acquired in a business combination are recognized at fair value at the acquisition date. Trademarks and licenses have a finite useful life which ranges from 3 to 7 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”, or “Research and development” 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 on computer software begins when the software is available for use and is calculated using the straight-line method over the estimated useful life, which does not exceed 4 years. 2.11 – 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 recognized at fair value at the acquisition date. Major additions and improvements are capitalized, while minor replacements and repairs are expensed and reported as “Cost of sales”, “Selling, general and administrative”, or “Research and development” 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 3-10 Computer and R&D equipment 3-6 Other 2-5 The Company evaluates each period whether there is reason to suspect that tangible assets or groups of assets held and used might 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. The Company also evaluates, and adjusts if appropriate, the assets’ useful lives, at each date or when impairment indicators are identified. When property, plant and equipment are retired or otherwise disposed of, the net book value of the assets is removed from the Company’s books. 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. Lease arrangements in which the Company has substantially all the risks and rewards of ownership are classified as capital leases. Assets leased under capital leases are included in “Property, plant and equipment, net” on the consolidated balance sheets and recorded at inception at the lower of their fair value and the present value of the minimum lease payments. They are depreciated over the shorter of the estimated useful life and the lease term unless there is a reasonable certainty that ownership will be obtained by the end of the lease term. The financial liability corresponding to the contractual obligation to proceed to future lease payments is included as “Long-term debt” on the consolidated balance sheets, as described in Note 2.14. Lease arrangements classified as operating leases are arrangements in which the lessor retains a significant portion of the risks and rewards of ownership of the leased assets. Payments made under operating leases are recognized on a straight-line basis over the lease period and reported as “Cost of sales”, “Selling, general and administrative”, or “Research and development” in the consolidated statements of income according to the intended use of the leased asset. 2.12 – 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 trading or available-for-sale non-recurring non-operating Equity-method investments are all entities over which the Company has the ability to exercise significant influence but not control, generally representing a shareholding of between 20% and 50% of the voting rights. These investments are valued under the equity-method and are initially recognized at cost. Goodwill on equity-method investments is included in the carrying value of the investment and is not individually tested for impairment. The Company’s share in the result of operations of equity-method investments is recognized in the consolidated statements of income on the line “Income (loss) on equity-method investments” and in the consolidated balance sheets as an adjustment to the carrying amount of the investments. Where there has been a change recognized directly in the equity of the investee, the Company recognizes its share in the adjustment, when applicable, directly in the consolidated statement of equity. The financial statements of the equity-method investments are prepared for the same reporting period as the Company or with a time lag not exceeding three months if the investee cannot issue consolidated financial statements within the closing timeframe requirements of the Company. At each period-end, non-recurring 2.13 – Provisions 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 had been incurred at the date of the consolidated financial statements and when the amount of the loss can be reasonably estimated. 2.14 – Long-term debt (a) Convertible debt The Company evaluates at initial recognition of a convertible debt the different components and features of the hybrid instruments and determines whether certain elements are embedded derivative instruments which require bifurcation. Components of convertible debt instruments that may be settled in cash upon conversion based on a net-share 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 (c) Capital leases Lease arrangements in which the Company has substantially all the risks and rewards of ownership are classified as capital leases. The Company reports the leased assets on the line “Property, plant and equipment, net” on the consolidated balance sheets and recognizes a financial liability for the contractual obligation to future lease payments, which is reported as “Long-term debt” on the consolidated balance sheets. Each lease payment is allocated between the debt repayment and interest expense. 2.15 – 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 overfunded or underfunded status of the defined benefit plans are calculated as the difference between plan assets and the projected benefit obligations. Significant 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 experience adjustments and changes in actuarial assumptions are recognized in “Accumulated Other Comprehensive Income (Loss)” in the consolidated statements of equity and are charged or credited to income over the employees’ expected average remaining working lives. Past service costs are recognized immediately in earnings, unless the changes to the pension scheme are conditional on the employees remaining in service for a specified period of time (the vesting period). In this case, the 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 vesting period. The net periodic benefit cost of the year is determined based on the assumptions used at the end of the previous year. 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) Other post-employment obligations The Company provides post-employment benefits to some of its retirees. The entitlement to these benefits is usually conditional on the employee remaining in service up to retirement age and to the completion of a minimum service period. The expected costs of these benefits are accrued over the period of employment using an accounting methodology similar to that for defined benefit pension plans. Actuarial gains and losses arising from experience adjustments, and changes in actuarial assumptions, are charged or credited to income over the expected average remaining working lives of the related employees. (c) 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 recognition of involuntary termination benefits, the Company distinguishes between one-time one-time One-time one-time one-time 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. (d) Profit-sharing and bonus plans The Company recognizes a liability and an expense for bonuses and profit-sharing plans when it is contractually obliged or where there is a past practice that has created a present obligation. (e) 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 experience adjustments, and changes in actuarial assumptions, are charged or credited to earnings in the period of change. These obligations are valued annually with the assistance of independent qualified actuaries. (f) Share-based compensation The Company grants unvested stock awards to senior executives and selected employees for services. The awards granted to employees vest over a three-year service period. For certain employees, awards contingently vest upon achieving certain performance conditions. The Company measures the cost of the awards based on the grant-date fair value of the awards, 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 on the shares during the requisite service period. That cost is recognized using graded vesting over the period during which an employee is required to provide service in exchange for the award or the requisite service period. Compensation is recognized only for the awards that ultimately vest. The compensation cost is recorded through earnings against equity, under “Capital surplus” in the consolidated statements of equity. The compensation cost is calculated based on the number of awards expected to vest, which includes assumptions on the number of awards to be forfeited due to the employees’ failing to fulfill the service condition, and forfeitures following the non-completion 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 at vesting date. 2.16 – 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 or options are shown in equity as a deduction, net of tax, from the proceeds. 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 equity attributable to the Company’s shareholders until the shares are cancelled, reissued or disposed of. 2.17 – 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 stockholders and distributions to stockholders. In the accompanying consolidated financial statements, “Other comprehensive income (loss)” and “Accumulated other comprehensive income” primarily consists of foreign currency translation adjustments, temporary unrealized gains (losses) on securities classified as available-for-sale, 2.18 – Revenue Recognition Revenue is recognized as follows: Net sales Revenue from products sold to customers is recognized when all the following conditions have been met: (a) persuasive evidence of an arrangement exists; (b) delivery has occurred; (c) the selling price is fixed or determinable; and (d) collection is reasonably assured. Revenue recognition usually occurs at the time of shipment. 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 declines in market prices. The Company accrues a provision for price protection based on a rolling historical price trend computed on a monthly basis 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 if required, to accommodate a significant change in the current market price. The short outstanding inventory time period, 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’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 end-user The Company’s insura

On July 3, 2014, the Company issued $1,000 million in principal amount of dual tranche senior unsecured convertible bonds (Tranche A for $600 million and Tranche B for $400 million), due 2019 and 2021, respectively. Tranche A bonds were issued as zero-coupon net-share Proceeds 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 at fair value based on a discount rate adjustment technique (income approach), which corresponds to a Level 3 fair value hierarchy measurement. The fair value of the liability component at initial recognition totalled $878 million and was estimated by calculating the present value of cash flows using a discount rate of 2.40% and 3.22% (including 1% per annum nominal interest), respectively, on each tranche, which were determined to be consistent with the market rates at the time for similar instruments with no conversion rights. An amount of $121 million, net of allocated issuance costs of $1 million, was recorded in shareholders’ equity as the value of the conversion features of the instruments. Unamortized debt discount and issuance costs totalled $74 million as at December 31, 2016 and $95 million as at December 31, 2015. Aggregate future maturities of total long-term debt (including current portion) at redemption value are as follows: December 31, 2016 2017 117 2018 115 2019 714 2020 114 2021 461 Thereafter 4 Total 1,525 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 debt discount and issuance costs on the dual tranche senior unsecured convertible bonds. Credit facilities The Company had unutilized committed medium-term credit facilities with core relationship banks totalling $558 million as of December 31, 2016. The Company also has two long-term amortizing credit facilities with the European Investment Bank as part of R&D funding programs.

Post-Employment and Other Long-Term Employees Benefits	15. 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 a December 31 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 continues to measure the vested benefits to which Italian employees are entitled as if they left the company immediately as of December 31, 2016, in compliance with U.S. GAAP guidance on determining vested benefit obligations for defined benefit pension plans.

The components of the net periodic benefit cost included the following: Pension Benefits Other Long-term Benefits Year ended Year ended Year ended Year ended Year ended Year ended Service cost 27 28 27 3 5 7 Interest cost 25 25 28 2 2 2 Expected return on plan assets (20 ) (22 ) (22 ) — — — Amortization of actuarial net loss (gain) 8 7 3 — — 2 Amortization of prior service cost 1 1 — — — 1 Effect of settlement — 1 1 — — — Effect of curtailment — — — (1 ) (1 ) — Net periodic benefit cost 41 40 37 4 6 12 The weighted average assumptions used in the determination of the benefit obligation and the plan assets for the pension plans and the other long-term benefits were as follows: Assumptions 2016 2015 Discount rate 2.57 % 3.19 % Salary increase rate 2.74 % 3.07 % Expected long-term rate of return on funds for the pension expense of the year 3.57 % 4.44 % The weighted average assumptions used in the determination of the net periodic benefit cost for the pension plans and the other long-term benefits were as follows: Assumptions 2016 2015 2014 Discount rate 3.19 % 3.03 % 3.83 % Salary increase rate 3.07 % 2.65 % 2.82 % Expected long-term rate of return on funds for the pension expense of the year 4.44 % 4.76 % 4.88 % 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 term of the benefit obligations concerned. 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 at December 31, 2016 and at December 31, 2015 is as follows: Percentage of Plan Assets at December Asset Category 2016 2015 Cash and cash equivalents 2 % 3 % Equity securities 29 % 27 % Government debt securities 3 % 2 % Corporate debt securities 26 % 26 % Investments in funds (a) 18 % 19 % Real estate 2 % 2 % Other (mainly insurance assets – contracts and reserves) 20 % 21 % Total 100 % 100 % (a) Investment in funds are composed approximately for one half of commingled funds mainly invested in corporate bonds for 55%, treasury bonds and notes for 35% and municipal bonds for 5% and for the other half of a multi-strategy funds invested in broadly diversified portfolios of corporate and government bonds, equity, fixed income and derivative instruments. As of December 31, 2016, the Company’s plan asset allocation is in line with the target fixed for each plan. The Company’s detailed pension plan asset allocation including the fair-value measurements of those plan assets as at December 31, 2016 is as follows: Total Quoted Prices in Significant Other Significant Cash and cash equivalents 11 11 — — Equity securities 137 6 131 — Government debt securities 13 12 1 — Corporate debt securities 125 4 121 — Investment funds 84 6 78 — Real estate 12 — 11 1 Other (mainly insurance assets – contracts and reserves) 95 — — 95 TOTAL 477 39 342 96 The Company’s detailed pension plan asset allocation including the fair-value measurements of those plan assets as at December 31, 2015 is as follows: Total Quoted Prices in Significant Other Significant Cash and cash equivalents 13 13 — — Equity securities 128 5 123 — Government debt securities 10 10 — — Corporate debt securities 123 4 119 — Investment funds 87 5 82 — Real estate 11 — 10 1 Other (mainly insurance assets – contracts and reserves) 101 — — 101 TOTAL 473 37 334 102 The fair value of insurance contracts is based on the value of the assets held by the provider. 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, 2016 and December 31, 2016 is presented as follows: Fair Value Measurements using Significant January 1, 2016 102 Contributions (employer and employee) 16 Actual return on plan assets (3 ) Benefits paid (6 ) Settlements (10 ) Foreign currency translation adjustment (3 ) December 31, 2016 96 For plan assets measured at fair value using significant unobservable inputs (Level 3), the reconciliation between January 1, 2015 and December 31, 2015 is presented as follows: Fair Value Measurements using Significant January 1, 2015 102 Contributions (employer and employee) 14 Actual return on plan assets 1 Benefits paid (3 ) Assets sold during the year (1 ) Settlements (9 ) Foreign currency translation adjustment (2 ) December 31, 2015 102 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 in each subsidiary of its asset allocation strategy, in such a way that the asset allocation is in line with the targeted asset allocation with reasonable boundaries. The Company’s asset portfolios are managed in such a way as to achieve adapted diversity and in certain jurisdictions they are entirely managed by the multi-employer funds. 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 $27 million in 2016, $28 million in 2015 and the Company expects to contribute cash of $28 million in 2017. The Company’s estimated future benefit payments as of December 31, 2016 are as follows: Years Pension Benefits Other Long-term Benefits 2017 36 3 2018 22 3 2019 32 5 2020 29 7 2021 36 3 From 2022 to 2026 233 27 The Company has certain defined contribution plans, which accrue benefits for employees on a pro-rata

Equity [Abstract]
Shareholders' Equity	16. SHAREHOLDERS’ EQUITY 16.1 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 at December 31, 2016 the number of shares of common stock issued was 911,030,420 shares (910,967,920 at December 31, 2015). As of December 31, 2016 the number of shares of common stock outstanding was 883,410,506 (878,537,339 at December 31, 2015). 16.2 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. On January 22, 2007, an option agreement was concluded between the Company and Stichting Continuïteit ST. This option agreement provides for the issuance of 540,000,000 preference shares. The Foundation can acquire preference shares upon payment of at least 25% of the par value of the preference shares to be issued in the event of actions which the board of the Foundation determines would be contrary to our interests, our shareholders and our other stakeholders and which in the event of a creeping acquisition or offer for our common shares are not supported by our Managing Board and Supervisory Board. The preference shares may remain outstanding for no longer than two years. In October 2016, the Company extended for another 10-year There were no preference shares issued as of December 31, 2016 and December 31, 2015 respectively. 16.3 Treasury stock Following the authorization by the Supervisory Board, announced on April 2, 2008, to repurchase up to 30 million shares of its common stock, the Company acquired 29,520,220 shares in 2008, also reflected at cost, as a reduction of the parent company stockholders’ equity. Additionally, pursuant to a resolution passed at the shareholders’ meeting held on June 13, 2014, the Company repurchased 20,000,000 shares in 2014 under the buy-back As of December 31, 2016, the Company owned a number of treasury shares equivalent to 27,619,914 compared to 32,430,581 as of December 31, 2015. The treasury shares have been designated for allocation under the Company’s share based remuneration programs of unvested shares. As of December 31, 2016, 35,300,306 of these treasury shares were transferred to employees under the Company’s share based remuneration programs, of which 4,810,667 in the year ended December 31, 2016. 16.4 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 (the options to acquire common shares in the share capital 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 vest and become exercisable immediately, while the shares resulting from these awards vest and therefore become available for trade evenly over three years (one third every year), with no market, performance or service conditions. The table below summarizes grants under the outstanding stock award plans as authorized by the Compensation Committee: Year of grant Options granted and Options waived at 2005 66,000 (15,000 ) 2006 66,000 (15,000 ) 2007 165,000 (22,500 ) 2008 165,000 (22,500 ) 2009 165,000 (7,500 ) 2010 172,500 (7,500 ) 2011 172,500 (30,000 ) 2012 180,000 (22,500 ) 2013 No options granted 2014 No options granted 2015 No options granted 2016 No options granted A summary of the options’ activity by plan for the years ended December 31, 2016 and December 31, 2015 is presented below: Year of grant Outstanding Exercised Expired / Outstanding Exercised Expired / Outstanding Shares 2005 22,115 (22,115 ) — — — — — — 2006 21,000 (18,000 ) — 3,000 (3,000 ) — — — 2007 46,500 (27,000 ) — 19,500 (12,000 ) — 7,500 — 2008 60,000 (21,000 ) — 39,000 (15,000 ) — 24,000 — 2009 75,000 (30,000 ) — 45,000 (10,000 ) — 35,000 — 2010 75,000 (30,000 ) — 45,000 — — 45,000 — 2011 97,500 (15,000 ) — 82,500 (15,000 ) — 67,500 — 2012 102,500 (7,500 ) — 95,000 (7,500 ) — 87,500 — The total intrinsic value of options exercised during the year 2016 amounted to less than $1 million compared to $1 million for the year 2015. The total intrinsic value of options outstanding as of December 31, 2016 amounted to $3 million. At the Company’s Annual General Meeting of Shareholders held on 21 June 2013, it was resolved to abolish and terminate the stock-based compensation for the Supervisory Board members and professionals. 16.5 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 along with selected employees (the “Employee Plan”). The awards are granted for services 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, whose vesting is subject to performance conditions. For the plans 2013, 2014 and 2015, the performance conditions consisted of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for two third of the total number of awards granted and of one internal target (cash flow compared to budget for the plans 2013 and 2014 and return on net assets compared to budget for the plan 2015), weighting for one third of the total number of awards granted. For the plan 2016, the performance conditions consisted of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for 80% of the total number of awards granted and of two internal targets (days of sales outstanding compared to the budget and return on net assets compared to budget), weighting for 20% of the total number of awards granted. All the awards vest over a three year service period (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). In addition, in 2013, 2014 and 2015 there was a Special Bonus granted to the Company’s CEO. The table below summarizes grants under the outstanding stock award plans as authorized by the Compensation Committee: Date of grant Plan name Number of shares Number of Number of shares July 22, 2013 2013 CEO Special Bonus 63,848 — — July 22, 2014 2014 CEO Special Bonus 34,483 — — July 22, 2014 2014 Employee Plan 6,458,435 — (1,939,222 ) December 18, 2014 2014 Employee Plan 500,775 — (31,332 ) March 24, 2015 2015 CEO Special Bonus 53,369 — — July 27, 2015 2015 Employee Plan 6,591,200 — (1,961,886 ) December 15, 2015 2015 Employee Plan 370,920 — (29,078 ) July 26, 2016 2016 Employee Plan 6,621,100 — ( ) December 19, 2016 2016 Employee Plan 376,800 — ( ) (*) As at December 31, 2016, a final determination of the achievement of the performance conditions had not yet been made by the Compensation Committee of the Supervisory Board. A summary of the unvested share activity by plan for the year ended December 31, 2016 is presented below: Unvested Shares Unvested Granted Forfeited / Cancelled on Vested Unvested 2013 CEO Special Bonus 28,378 — — — (21,283 ) 7,095 2013 Employee Plan 1,462,359 — (9,767 ) — (1,452,592 ) — 2014 CEO Special Bonus 22,989 — — — (11,494 ) 11,495 2014 Employee Plan 3,246,106 — (35,574 ) — (1,599,079 ) 1,611,453 2015 CEO Special Bonus — 53,369 — — (17,790 ) 35,579 2015 Employee Plan 6,931,175 — (63,228 ) (1,990,964 ) (1,706,244 ) 3,170,739 2016 Employee Plan — 6,997,900 (21,295 ) — (2,185 ) 6,974,420 Total 11,691,007 7,051,269 (129,864 ) (1,990,964 ) (4,810,667 ) 11,810,781 The grant date fair value of unvested shares granted to the CEO under the 2013 CEO Special Bonus Plan was $9.35. On the 2013 CEO Special Bonus Plan, the fair value of the unvested shares granted reflected 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 2013 Employee Plan was $9.55. On April 28, 2014, the Compensation Committee approved the statement that one performance condition was fully met. Consequently, the compensation expense recorded on the 2013 Employee Plan reflects the statement that one third of the awards granted will fully vest, as far as the service condition is met. The grant date fair value of unvested shares granted to the CEO under the 2014 CEO Special Bonus Plan was $9.35. On the 2014 CEO Special Bonus Plan, the fair value of the unvested shares granted reflected 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 2014 Employee Plan was $9.23. On March 24, 2015, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, one performance condition was fully met. Consequently, the compensation expense recorded on the 2014 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – one third of the awards granted will fully vest, as far as the service condition is met. The grant date fair value of unvested shares granted to employees under the 2015 Employee Plan was $7.62. On April 26, 2016, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, one performance condition was fully met. Consequently, the compensation expense recorded on the 2015 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – one third 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 2016 Employee Plan was $6.37. Moreover, for the portion of the shares subject to performance conditions (3,074,320 shares) the Company estimates the number of awards expected to vest by assessing the probability of achieving the performance conditions. At December 31, 2016, a final determination of the achievement of the performance conditions had not yet been made by the Compensation Committee of the Supervisory Board. However, the Company has estimated that 45% of the awards subject to performance conditions are expected to vest. Consequently, the compensation expense recorded for the 2016 Employee Plan reflects the vesting of 45% 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 2017. The following table illustrates the classification of pre-payroll December 31, December 31, December 31, 2016 2015 2014 Cost of sales 7 7 6 Selling, general and administrative 17 17 16 Research and development 14 14 14 Total pre-payroll 38 38 36 The fair value of the shares vested in 2016 was $42 million compared to $35 million for 2015. Compensation cost, excluding payroll tax and social contribution, capitalized as part of inventory was $2 million at each of December 31, 2016, 2015 and 2014. As of December 31, 2016 there was $35 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 9 months. The total deferred income tax benefit recognized in the consolidated statements of income related to unvested share-based compensation expense amounted to $2 million, $2 million and $1 million for the years ended December 31, 2016, 2015 and 2014, respectively. 16.6 Accumulated other comprehensive income (loss) attributable to parent company stockholders The table below details the changes in AOCI attributable to the company’s stockholders by component, net of tax, for the years ended December 31, 2016, 2015 and 2014: Gains (Losses) Gains (Losses) on Available-For-Sale Defined Benefit Foreign Currency Total December 31, 2013 38 1 (100 ) 1,085 1,024 Cumulative tax impact (5 ) — 23 — 18 December 31, 2013, net of tax 33 1 (77 ) 1,085 1,042 OCI before reclassifications (116 ) 1 (76 ) (272 ) (463 ) Amounts reclassified from AOCI 2 — 6 — 8 OCI for the year ended December 31, 2014 (114 ) 1 (70 ) (272 ) (455 ) Cumulative tax impact 5 — 21 — 26 OCI for the year ended December 31, 2014, net of tax (109 ) 1 (49 ) (272 ) (429 ) December 31, 2014 (76 ) 2 (170 ) 813 569 Cumulative tax impact — — 44 — 44 December 31, 2014, net of tax (76 ) 2 (126 ) 813 613 OCI before reclassifications (117 ) — (2 ) (202 ) (321 ) Amounts reclassified from AOCI 170 — 12 (10 ) 172 OCI for the year ended December 31, 2015 53 — 10 (212 ) (149 ) Cumulative tax impact — — (4 ) — (4 ) OCI for the year ended December 31, 2015, net of tax 53 — 6 (212 ) (153 ) December 31, 2015 (23 ) 2 (160 ) 601 420 Cumulative tax impact — — 40 — 40 December 31, 2015, net of tax (23 ) 2 (120 ) 601 460 OCI before reclassifications (33 ) — (25 ) (57 ) (115 ) Amounts reclassified from AOCI 9 — 15 — 24 OCI for the year ended December 31, 2016 (24 ) — (10 ) (57 ) (91 ) Cumulative tax impact — — 2 — 2 OCI for the year ended December 31, 2016, net of tax (24 ) — (8 ) (57 ) (89 ) December 31, 2016 (47 ) 2 (170 ) 544 329 Cumulative tax impact — — 42 — 42 December 31, 2016, net of tax (47 ) 2 (128 ) 544 371 Items reclassified out of Accumulated Other Comprehensive Income for the years ended December 31, 2016, 2015 and 2014 are listed in the table below: Details about AOCI components Amounts Amounts Amounts Affected line item in the statement where net income (loss) is presented Gains (Losses) on Cash Flow Hedges Foreign exchange derivative contracts (7 ) (105 ) (1 ) Cost of sales Foreign exchange derivative contracts — (14 ) (1 ) Selling, general and administrative Foreign exchange derivative contracts (2 ) (51 ) — Research and development — — — Income tax benefit (expense) (9 ) (170 ) (2 ) Net of tax Defined Benefit Pension Plan Items Amortization of actuarial gains (losses) (1 ) — — Cost of sales Amortization of actuarial gains (losses) (8 ) (5 ) (1 ) Selling, general and administrative Amortization of actuarial gains (losses) (6 ) (6 ) (4 ) Research and development Amortization of prior service cost — (1 ) (1 ) Research and development 4 4 1 Income tax benefit (expense) (11 ) (8 ) (5 ) Net of tax Foreign currency translation adjustment Realized gain on disposal of investments — 10 — Income (loss) on equity-method investments — — — Income tax benefit (expense) — 10 — Net of tax Total reclassifications for the year (20 ) (168 ) (7 ) Attributable to noncontrolling interest — — — Attributable to the Company’s stockholders (20 ) (168 ) (7 ) 16.7 Dividends The Annual General Meeting of Shareholders held on May 25, 2016, authorized the distribution of a cash dividend of $0.24 per outstanding share of the Company’s common stock, to be distributed in quarterly installments of $0.06 in each of the second, third and fourth quarters of 2016 and first quarter of 2017. $53 million corresponding to the first installment, $53 million corresponding to the second installment and $47 million corresponding to the third installment were paid during 2016.

The effect of the tax benefits, from tax holidays for countries which are profitable, on basic earnings per share was $0.05, $0.05 and $0.07 for the years ended December 31, 2016, 2015, and 2014, 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, 2022. 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.

As of December 31, 2016, the Company and its subsidiaries have gross deferred tax assets on tax loss carryforwards and investment credits that expire starting 2017, as follows: Year 2017 16 2018 89 2019 80 2020 16 2021 3 Thereafter 600 Total 804 The valuation allowance for a particular tax jurisdiction is allocated between current and non-current -0.04% The amounts of deferred tax benefit (expense) recorded as a component of other comprehensive income (loss) was $(1) million and $(3) million in 2016 and 2015, respectively. They were related primarily to the tax effects of the recognized unfunded status on defined benefits plan. The cumulative amount of distributable earnings related to the Company’s investments in foreign subsidiaries and corporate joint ventures was $785 million and $626 million as at December 31, 2016 and December 31, 2015, respectively. Due to the Company’s legal and tax structure, with the parent company established in the Netherlands, there was no significant tax impact from the distribution of earnings 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. A reconciliation of 2016, 2015 and 2014 beginning and ending amounts of unrecognized tax benefits is as follows: December 31, December 31, December 31, Balance at beginning of year 226 313 255 Additions based on tax positions related to the current year 34 38 51 Additions for tax positions of prior years 1 — 43 Reduction for tax positions of prior years (13 ) (48 ) (2 ) Settlements — (48 ) Prepayment — (3 ) (5 ) Reductions due to lapse of statute of limitations (4 ) (1 ) — Foreign currency translation (6 ) (25 ) (29 ) Balance at end of year 238 226 313 At December 31, 2016 and 2015, $195 million and $180 million, respectively, of unrecognized tax benefits were classified as a reduction of deferred tax assets. It is reasonably possible that certain of the uncertain tax positions disclosed in the table above could increase 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. 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 $1 million in 2016, $1 million in 2015, $27 million in 2014 and not material in the previous years. At December 31, 2016 and 2015, accrued interest and penalties amounted to $9 million. The tax years that remain open for review in the Company’s major tax jurisdictions, including France, Italy, United States and India, are from 1996 to 2016.

Contingencies, Claims and Legal Proceedings	23. CONTINGENCIES, CLAIMS AND LEGAL PROCEEDINGS The Company is subject to possible loss contingencies arising in the ordinary course of business. These include but are not limited to: warranty cost on the products of the Company, breach of contract claims, claims for unauthorized use of third-party intellectual property, 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 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. The Company is otherwise also involved in various lawsuits, claims, investigations and proceedings incidental to its business and operations. 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, 2016, provisions for estimated probable losses with respect to claims and legal proceedings were not considered material.

Financial Instruments and Risk Management	24. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT 24.1 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 CFO, 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 the management of 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 operating units. 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 Investor Service and A- Market risk Foreign exchange risk 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, primarily with respect to 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. To manage their foreign exchange risk arising from foreign-currency-denominated assets and liabilities, subsidiaries use forward contracts and purchased currency options. 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 intercompany transactions that cover a large part of its research and development, selling, general and administrative expenses as well as a portion of its front-end 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 on the following month. As such, the foreign exchange exposure of the Company, which consists in the balance sheet positions and other contractually agreed transactions, is always close to zero and any movement in the foreign exchange rates will not therefore influence the exchange effect on items of the consolidated statement of income. Any discrepancy from 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 in 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 $375 million, $372 million and $286 million at December 31, 2016, 2015 and 2014, respectively. The principal currencies covered at the end of the year 2016 are the Euro, the Japanese yen, the Singapore dollar, the Indian rupee, the Swiss franc, the China Yuan Renminbi, the British pound 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, 2016 have remaining terms of 3 days to 254 days, maturing on average after 26 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 front-end 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, 2016, the Company recorded an increase in cost of sales of $7 million and an increase in operating expenses of $2 million, related to the realized losses incurred on such hedged transactions. For the year ended December 31, 2015, the Company recorded an increase in cost of sales of $105 million and an increase in operating expenses of $65 million, related to the realized losses incurred on such hedged transactions. For the year ended December 31, 2014, the Company recorded an increase in cost of sales of $1 million and an increase in operating expenses of $1 million, related to the realized losses incurred on such hedged transactions. No significant ineffective portion of the hedge was recorded on the line “Other income and expenses, net” of the consolidated statements of income for the years ended December 31, 2016, 2015 and 2014. The notional amount of foreign currency forward contracts and currency options, including collars, designated as cash flow hedge totaled $1,370 million, $1,449 million and $1,386 million at December 31, 2016, 2015 and 2014, respectively. The forecasted transactions hedged at December 31, 2016 were determined to have a high probability of occurring. As of December 31, 2016, $47 million of deferred losses on derivative instruments included in “Accumulated other comprehensive income (loss)” were expected to be reclassified as earnings during the next 12 months based on the monthly forecasted research and development expenses, corporate costs and semi-finished manufacturing costs. No amount was reclassified as “Other income and expenses, net” into the consolidated statement of income from “Accumulated other comprehensive income (loss)” in the consolidated statement of equity. Foreign currency forward contracts, currency options and collars designated as cash flow hedge outstanding as of December 31, 2016 have remaining terms of 4 days to 19 months, maturing on average after 153 days. As at December 31, 2016, 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 Notional amount for hedge on Forward contracts 237 347 Currency collars 248 387 In millions of Singapore dollars Notional amount for hedge on Notional amount for hedge on Forward contracts — 123 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 be exposed to equity security price risk for investments in public entities. In order to hedge the exposure to this market risk, the Company may enter into certain derivative hedging transactions. Information on fair value of derivative instruments and their location in the consolidated balance sheets as at December 31, 2016 and December 31, 2015 is presented in the table below: As at December 31, 2016 As at December 31, 2015 Asset Derivatives Balance sheet location Fair value Balance sheet location Fair value Derivatives designated as a hedge: Foreign exchange forward contracts Other current assets 1 Other current assets 3 Currency collars Other non-current — Other non-current 1 Currency collars Other current assets — Other current assets 1 Total derivatives designated as a hedge 1 5 Derivatives not designated as a hedge: Foreign exchange forward contracts Other current assets 1 Other current assets 1 Total derivatives not designated as a hedge: 1 1 Total Derivatives 2 6 As at December 31, 2016 As at December 31, 2015 Liability Derivatives Balance sheet location Fair value Balance sheet location Fair value Derivatives designated as a hedge: Foreign exchange forward contracts Other payables and accrued liabilities (31 ) Other payables and accrued liabilities (18 ) Currency collars Other long-term liabilities (1 ) Other long-term liabilities — Currency collars Other payables and accrued liabilities (11 ) Other payables and accrued liabilities (6 ) Total derivatives designated as a hedge (43 ) (24 ) Derivatives not designated as a hedge: Foreign exchange forward contracts Other payables and accrued liabilities (2 ) Other payables and accrued liabilities (1 ) Total derivatives not designated as a hedge: (2 ) (1 ) Total Derivatives (45 ) (25 ) The effect on the consolidated statements of income for the year ended December 31, 2016 and December 31, 2015 and on the “Accumulated other comprehensive income (loss)” (“AOCI”) as reported in the statements of equity as at December 31, 2016 and December 31, 2015 of derivative instruments designated as cash flow hedge is presented in the table below: Gain (loss) deferred in Location of gain (loss) reclassified Gain (loss) reclassified from December 31, December 31, December 31, December 31, Foreign exchange forward contracts (24 ) (14 ) Cost of sales (5 ) (63 ) Foreign exchange forward contracts (2 ) (1 ) Selling, general and administrative — (8 ) Foreign exchange forward contracts (8 ) (4 ) Research and development (1 ) (29 ) Currency collars (8 ) (3 ) Cost of sales (2 ) (42 ) Currency collars (1 ) — Selling, general and administrative — (6 ) Currency collars (4 ) (1 ) Research and development (1 ) (22 ) Total (47 ) (23 ) (9 ) (170 ) No significant ineffective portion of the cash flow hedge relationships was recorded in earnings for the years ended December 31, 2016 and December 31, 2015. No amount was excluded from effectiveness measurement on foreign exchange forward contracts and collars. The effect on the consolidated statements of income for the year ended December 31, 2016 and December 31, 2015 of derivative instruments not designated as a hedge is presented in the table below: Location of gain recognized in earnings Gain recognized in earnings December 31, 2016 December 31, 2015 Foreign exchange forward contracts Other income and expenses, net (3 ) 11 Total (3 ) 11 The Company did not enter into any derivative containing significant credit-risk-related contingent features. The Company entered into currency collars as combinations of two options, which are reported, for accounting purposes, on a net basis. The fair value of these collars represented as at December 31, 2016 liabilities totalling $12 million (a gross amount of $0 million recognized assets offset with a liability of $12 million). In addition, the Company entered into other derivative instruments, primarily forward contracts, which are governed by standard International Swaps and Derivatives Association (“ISDA”) agreements, which are not offset in the statement of financial position, and representing total assets of $2 million and liabilities of $33 million as at December 31, 2016. Credit risk 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. 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 credit quality of the customer, taking into account its financial position, past experience and other factors. Individual risk limits are set based on internal and external ratings in accordance with limits set by management. The utilization of credit limits is regularly monitored. Sales to customers are primarily settled in cash. At December 31, 2016 and 2015, 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. Liquidity risk Prudent liquidity risk management includes maintaining sufficient cash equivalents 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 Management monitors rolling forecasts of the Company’s liquidity reserve on the basis of expected cash flows. 24.2 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 value for shareholders and benefits and returns for other stakeholders, as to maintain an optimal capital structure. In order to maintain or adjust the capital structure, the Company may review the amount of dividends paid to shareholders, return capital to shareholders, or issue new shares. Consistent with others in the industry, the Company monitors capital on the basis of the net debt-to-equity non-current 24.3 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 at December 31, 2016: Fair Value Measurements using December 31, Quoted Prices in Significant Other Significant Marketable securities – U.S. Treasury Bonds 335 335 — — Equity securities classified as available-for-sale 11 11 — — Equity securities classified as held-for-trading 8 8 — — Derivative instruments designated as cash flow hedge 1 — 1 — Derivative instruments designated as cash flow hedge (43 ) — (43 ) — Derivative instruments not designated as cash flow hedge 1 — 1 — Derivative instruments not designated as cash flow hedge (2 ) — (2 ) — Contingent consideration on business combinations (12 ) — — (12 ) Total 299 354 (43 ) (12 ) The table below details financial assets (liabilities) measured at fair value on a recurring basis as at December 31, 2015: Fair Value Measurements using December 31, Quoted Prices in Significant Other Significant Marketable securities – U.S. Treasury Bonds 335 335 — — Equity securities classified as available-for-sale 11 11 — — Equity securities classified as held-for-trading 8 8 — — Derivative instruments designated as cash flow hedge 5 — 5 — Derivative instruments designated as cash flow hedge (24 ) — (24 ) — Derivative instruments not designated as cash flow hedge 1 — 1 — Derivative instruments not designated as cash flow hedge (1 ) — (1 ) — Total 335 354 (19 ) — For assets (liabilities) measured at fair value on a recurring basis using significant unobservable inputs (Level 3), the reconciliation between January 1, 2016 and December 31, 2016 is presented as follows: Fair Value Measurements using Significant January 1, 2016 — Contingent consideration on business combination (12 ) December 31, 2016 (12 ) Amount of total losses for the period included in earnings attributable to assets still held at the reporting date — On July 28, 2016, the Company completed a transaction to acquire ams’ (SIX: AMS) assets and workforce related to Near-Field Communication (NFC) and Radio-frequency identification (RFID) Reader business, as described in Note 7. The purchase price consideration includes a cash payment of $78 million and the acquisition-date fair value of a sales earn-out No asset was measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as at December 31, 2015. The liability component of the convertible bonds issued on July 3, 2014 was measured at initial recognition at fair value based on a discount rate adjustment technique (income approach), which corresponds to a Level 3 fair value hierarchy measurement. The fair value of the liability component at initial recognition totaled $878 million and was estimated by calculating the present value of cash flows using a discount rate of 2.40% and 3.22% (including 1% per annum nominal interest), respectively, on each tranche, as the market rates for similar instruments with no conversion rights. The liability component of the convertible bonds was subsequently reported at amortized cost. The liability component will be accreted to par value over the expected life of the instrument, five years and seven years respectively for each tranche. The assets held for sale are reported at the lower of net book value and fair value less costs to sell. For fair value measurements using significant unobservable inputs (Level 3), fair value is estimated based on the estimated price that a market participant would pay on a sale transaction for these assets. The business combination concluded on July 28, 2016 resulted in the recognition at fair value on a non-recurring in-process The Company evaluated in 2016 and 2015 for impairment the aggregate carrying amount of cost-method investments. No impairment charge was recorded on these investments in 2016 and in 2015. Following identified changes in circumstances in 2014 evidencing that there may have been a significant adverse effect on the fair value of certain cost-method investments, $3 million of the aggregate carrying amount of these investments was evaluated for impairment in 2014, which generated an other-than-temporary impairment charge of $3 million, reported on the line “Gain (loss) on financial instruments, net” on the consolidated statement of income for the year ended December 31, 2014. The following table includes additional fair value information on financial assets and liabilities as at December 31, 2016 and 2015: 2016 2015 Level Carrying Estimated Fair Carrying Estimated Fair Cash equivalents (1) 1 960 960 1,099 1,099 Long-term debt – Bank loans (including current portion) 2 525 525 708 708 – Senior unsecured convertible bonds (2) 1 926 1,127 904 960 (1) Cash equivalents primarily correspond to deposits at call with banks. (2) The carrying amount of the senior unsecured convertible bonds as reported above corresponds to the liability component only, since, at initial recognition, an amount of $121 million was recorded directly in shareholders’ equity as the value of the equity instrument embedded in the issued convertible bonds. No securities were in an unrealized loss position as at December 31, 2016 and December 31, 2015. The methodologies used to estimate fair value are as follows: Debt securities classified as available-for-sale The fair value of these debt securities is estimated based upon quoted market prices for identical instruments. Foreign exchange forward contracts, currency options and collars The fair value of these instruments is estimated based upon quoted market prices for similar instruments. Marketable securities classified as available-for-sale The fair values of these instruments are estimated based upon market prices for identical instruments. Equity securities classified as available-for-sale The fair values of these instruments are estimated based upon market prices for identical instruments. Trading equity securities The fair value of these instruments is estimated based upon quoted market prices for the same instruments. Equity securities carried at cost The non-recurring Long-term debt and current portion of long-term debt The fair value of bank loans is determined by estimating future cash flows on a borrowing-by-borrowing The senior unsecured convertible bonds have been trading on the open market segment of the Frankfurt Stock Exchange since issuance on July 3, 2014. The fair value of these instruments is the observable price of the bonds on that market. Cash and cash equivalents, accounts receivable, short-term borrowings, and accounts payable The carrying amounts reflected in the consolidated financial statements are reasonable estimates of fair value due to the relatively short period of time between the origination of the instruments and their expected realization.

Segment Reporting [Abstract]
Segment Information	26. SEGMENT INFORMATION The Company operates in two business areas: Semiconductors and Subsystems. In the Semiconductors business area, 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 further participates in the manufacturing value chain of Smartcard products, which includes the production and sale of both silicon chips and Smartcards. During the first quarter of 2016, the internal organization changed to align with the Company’s strategic focus on Smart Driving and on Internet of Things applications. Comparative numbers were restated accordingly. The Company’s reportable segments are as follows: • Automotive and Discrete Group (ADG), comprised of all dedicated automotive ICs (both digital and analog), and discrete and power transistor products. • Analog and MEMS Group (AMG), comprised of low-power high-end • Microcontrollers and Digital ICs Group (MDG), comprised of general purpose and secure microcontrollers, EEPROM memories, and digital ASICs as well as restructured businesses such as Set-Top-box ST-Ericsson “Others” includes all the financial values related to the Imaging Product Division (including the sensors and modules from our Time of Flight technology), Subsystems and other products, as well as items not allocated to the segments such as impairment, restructuring charges and other related closure costs, unused capacity charges, strategic or special research and development programs and other minor unallocated expenses such as: certain corporate-level operating expenses, patent claims and litigation, and other costs that are not allocated to the segments. In the Subsystems business area, the Company designs, develops, manufactures and markets subsystems and modules for the telecommunications, automotive and industrial markets including mobile phone accessories, battery chargers, ISDN power supplies and in-vehicle 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, selling, general and administrative expenses and a part of research and development expenses. In compliance with the Company’s internal policies, certain costs are not allocated to the segments, including impairment, restructuring charges and other related closure costs, unused capacity charges, phase-out start-up one-time 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.

Accounting Policies (Policies)

Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Principles of consolidation	2.1 – Principles of consolidation The Company’s consolidated financial statements include the assets, liabilities, results of operations and cash flows of its majority-owned subsidiaries. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases. Intercompany balances and transactions have been eliminated in consolidation. 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. Assets, liabilities, and the noncontrolling interest of newly consolidated VIEs are initially measured at fair value in the same manner as if the consolidation resulted from a business combination. 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 is reported on the line “Noncontrolling interest” in the consolidated financial statements.
Use of estimates	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 returns and allowances, • 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 or sold, including intangibles, goodwill, investments and tangible assets, • annual and trigger-based impairment review of goodwill and intangible assets, as well as the assessment, in each reporting period, of events, which could trigger impairment testing on long-lived assets, • estimated value of the consideration to be received and used as fair value for asset groups classified as assets held for sale and the assessment of probability of realizing the sale, • assessment of other-than-temporary impairment charges on financial assets, including equity-method investments, • recognition and measurement of restructuring charges and other related exit costs, • assumptions used in assessing the number of awards expected to vest on stock-based compensation plans, • assumptions used in calculating pension obligations and other long-term employee benefits, and • determination of the amount of taxes 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.
Foreign currency	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 largely incurred in the countries of the Euro zone and other non-U.S. 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 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 at the closing exchange rate as of the balance sheet date; (b) income and expenses for each consolidated statement of income presented are translated at the average monthly exchange rate; (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.
Cash and cash equivalents	2.4 – Cash and cash equivalents Cash and cash equivalents includes cash on hand, deposits held at call with external financial institutions and other short-term highly liquid investments with original maturities to the Company 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. Bank overdrafts are not netted against cash and cash equivalents and are shown as part of current liabilities on the consolidated balance sheets.
Trade accounts receivable	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. They are reported net of allowances for doubtful accounts. The Company maintains an allowance for doubtful accounts for potential estimated losses resulting from its customers’ inability to make required payments. The Company bases its estimates on historical collection trends and records an allowance accordingly. Additionally, the Company evaluates its customers’ financial condition periodically and records an allowance for any specific account it considers as doubtful. The carrying amount of the receivable is thus reduced through the use of an allowance account, and the amount of the charge is recognized on the line “Selling, general and administrative” in the consolidated statements of income. Subsequent recoveries, if any, of amounts previously provided for are credited against the same line in the consolidated statements of income. When a trade accounts receivable is uncollectible, it is written-off 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.
Inventories	2.6 – Inventories Inventories are stated at the lower of cost or market value. Cost is based on the weighted average cost by adjusting standard cost to approximate actual manufacturing costs on a quarterly basis; the cost is therefore dependent on the Company’s manufacturing performance. In the case of underutilization of manufacturing facilities, the costs associated with the unused capacity are not included in the valuation of inventories but charged directly to cost of sales. Market value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses and cost of completion. The Company performs, on a continuous basis, inventory write-offs of products, which have the characteristics of slow-moving, old production date and technical obsolescence. Indeed, the Company evaluates its product inventory to identify obsolete or slow-selling items and records a specific reserve if the Company estimates the inventory will eventually become obsolete. Reserve for obsolescence is estimated for excess uncommitted inventory based on the previous quarter sales, order backlog and production plans.
Income taxes	2.7 – Income taxes Income tax for the period comprises current and deferred income tax. Current income tax represents the income tax expected to be paid or the tax benefit expected to be received related to the current year taxable profit and loss in each tax jurisdiction. Deferred income tax is recognized, using the liability method, for all temporary differences arising between the tax bases of assets and liabilities and their carrying amount in the consolidated financial statements. However, deferred income tax is not accounted for if it arises from the initial recognition of an asset or liability in a transaction other than a business combination that, at the time of the transaction, affects neither accounting nor taxable profit and loss. Moreover, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. 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 benefit (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 the 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 impact the deferred tax asset and do not result in any adjustments prior to vesting. When the actual tax deduction is determined, generally upon vesting, it is compared to the deferred tax asset as recognized over the vesting period. When a windfall tax benefit is determined (as the excess tax benefit of the actual tax deduction over the deferred tax asset) the excess tax benefit is recorded in equity on the line “Capital surplus” on the consolidated statements of equity. In case of shortfall, only the actual tax benefit is to be recognized in the consolidated financial statements. The Company writes off the deferred tax asset at the level of the actual tax deduction by charging first capital surplus to the extent of the pool of windfall benefits available from prior years, and then in the consolidated statements of income on the line “Income tax benefit (expense)”. When the settlement of an award results in a net operating loss (“NOL”) carryforward, or increase of existing NOLs, the excess tax benefit and the corresponding credit to capital surplus is not recorded until the deduction reduces income tax payable. At each reporting date, the Company assesses all material open income tax positions in all tax jurisdictions to determine any uncertain tax positions. The Company uses a two-step more-likely-than-not
Assets held for sale	2.8 – Assets held for sale Asset groups are classified as assets held for sale when their carrying amount is to be recovered principally through a sale transaction rather than through continuing use. The asset groups are classified as assets held for sale when the following conditions have been met: management has approved the plan to sell; assets are available for immediate sale; assets are actively being marketed; sale is probable within one year; price is reasonable in the market and it is unlikely that there will be significant changes in the assets to be sold or a withdrawal to the plan to sell. Asset groups classified as held for sale are reported as current assets in the consolidated balance sheets at the lower of their carrying amount and fair value less costs to sell. Long-lived assets classified as held for sale are no longer depreciated. When the held-for-sale
Business combinations and goodwill	2.9 – Business combinations and goodwill The purchase accounting method is applied to all business combinations. The identifiable assets acquired, equity instruments issued, and liabilities assumed are measured at fair value on the acquisition date. Any contingent purchase price and acquired contingencies are recorded at fair value on the acquisition date and at each reporting date. Acquisition-related transaction costs and restructuring costs relating to the acquired business are expensed as incurred. Acquired in-process Goodwill represents the excess of the aggregate of the consideration transferred and the fair value of any noncontrolling interest in the acquiree over the net of the acquisition-date amount of the identifiable assets acquired and liabilities assumed. Goodwill is carried at cost less accumulated impairment losses. Goodwill is not amortized but is tested annually for impairment, or more frequently if indicators of impairment exist. Goodwill subject to potential impairment is tested at a reporting unit level. The impairment test determines whether the fair value of each reporting unit for which goodwill is allocated is lower than the total carrying amount of relevant net assets allocated to such reporting unit, including its allocated goodwill. If lower, the implied fair value of the reporting unit goodwill is then compared to the carrying value of the goodwill and an impairment charge is recognized for any excess. 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.
Intangible assets with finite useful lives	2.10 – Intangible assets with finite useful lives Intangible assets subject to amortization include the intangible assets purchased from third parties recorded at cost and intangible assets acquired in business combinations recorded at fair value. Amortization begins when the intangible asset is available for use and is calculated using the straight-line method to allocate the cost of the intangible assets over their estimated useful lives. The carrying value of intangible assets with finite useful lives is evaluated whenever changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized in the consolidated statements of income on the line “Impairment, restructuring charges and other related closure costs” 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. Trademarks, technologies and licenses Separately acquired trademarks and licenses are recorded at historical cost. Trademarks and licenses acquired in a business combination are recognized at fair value at the acquisition date. Trademarks and licenses have a finite useful life which ranges from 3 to 7 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”, or “Research and development” 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 on computer software begins when the software is available for use and is calculated using the straight-line method over the estimated useful life, which does not exceed 4 years.
Property, plant and equipment	2.11 – 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 recognized at fair value at the acquisition date. Major additions and improvements are capitalized, while minor replacements and repairs are expensed and reported as “Cost of sales”, “Selling, general and administrative”, or “Research and development” 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 3-10 Computer and R&D equipment 3-6 Other 2-5 The Company evaluates each period whether there is reason to suspect that tangible assets or groups of assets held and used might 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. The Company also evaluates, and adjusts if appropriate, the assets’ useful lives, at each date or when impairment indicators are identified. When property, plant and equipment are retired or otherwise disposed of, the net book value of the assets is removed from the Company’s books. 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. Lease arrangements in which the Company has substantially all the risks and rewards of ownership are classified as capital leases. Assets leased under capital leases are included in “Property, plant and equipment, net” on the consolidated balance sheets and recorded at inception at the lower of their fair value and the present value of the minimum lease payments. They are depreciated over the shorter of the estimated useful life and the lease term unless there is a reasonable certainty that ownership will be obtained by the end of the lease term. The financial liability corresponding to the contractual obligation to proceed to future lease payments is included as “Long-term debt” on the consolidated balance sheets, as described in Note 2.14. Lease arrangements classified as operating leases are arrangements in which the lessor retains a significant portion of the risks and rewards of ownership of the leased assets. Payments made under operating leases are recognized on a straight-line basis over the lease period and reported as “Cost of sales”, “Selling, general and administrative”, or “Research and development” in the consolidated statements of income according to the intended use of the leased asset.
Investments in equity securities	2.12 – 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 trading or available-for-sale non-recurring non-operating Equity-method investments are all entities over which the Company has the ability to exercise significant influence but not control, generally representing a shareholding of between 20% and 50% of the voting rights. These investments are valued under the equity-method and are initially recognized at cost. Goodwill on equity-method investments is included in the carrying value of the investment and is not individually tested for impairment. The Company’s share in the result of operations of equity-method investments is recognized in the consolidated statements of income on the line “Income (loss) on equity-method investments” and in the consolidated balance sheets as an adjustment to the carrying amount of the investments. Where there has been a change recognized directly in the equity of the investee, the Company recognizes its share in the adjustment, when applicable, directly in the consolidated statement of equity. The financial statements of the equity-method investments are prepared for the same reporting period as the Company or with a time lag not exceeding three months if the investee cannot issue consolidated financial statements within the closing timeframe requirements of the Company. At each period-end, non-recurring
Provisions	2.13 – Provisions 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 had been incurred at the date of the consolidated financial statements and when the amount of the loss can be reasonably estimated.
Long-term debt	2.14 – Long-term debt (a) Convertible debt The Company evaluates at initial recognition of a convertible debt the different components and features of the hybrid instruments and determines whether certain elements are embedded derivative instruments which require bifurcation. Components of convertible debt instruments that may be settled in cash upon conversion based on a net-share 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 (c) Capital leases Lease arrangements in which the Company has substantially all the risks and rewards of ownership are classified as capital leases. The Company reports the leased assets on the line “Property, plant and equipment, net” on the consolidated balance sheets and recognizes a financial liability for the contractual obligation to future lease payments, which is reported as “Long-term debt” on the consolidated balance sheets. Each lease payment is allocated between the debt repayment and interest expense.
Employee benefits	2.15 – 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 overfunded or underfunded status of the defined benefit plans are calculated as the difference between plan assets and the projected benefit obligations. Significant 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 experience adjustments and changes in actuarial assumptions are recognized in “Accumulated Other Comprehensive Income (Loss)” in the consolidated statements of equity and are charged or credited to income over the employees’ expected average remaining working lives. Past service costs are recognized immediately in earnings, unless the changes to the pension scheme are conditional on the employees remaining in service for a specified period of time (the vesting period). In this case, the 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 vesting period. The net periodic benefit cost of the year is determined based on the assumptions used at the end of the previous year. 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) Other post-employment obligations The Company provides post-employment benefits to some of its retirees. The entitlement to these benefits is usually conditional on the employee remaining in service up to retirement age and to the completion of a minimum service period. The expected costs of these benefits are accrued over the period of employment using an accounting methodology similar to that for defined benefit pension plans. Actuarial gains and losses arising from experience adjustments, and changes in actuarial assumptions, are charged or credited to income over the expected average remaining working lives of the related employees. (c) 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 recognition of involuntary termination benefits, the Company distinguishes between one-time one-time One-time one-time one-time 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. (d) Profit-sharing and bonus plans The Company recognizes a liability and an expense for bonuses and profit-sharing plans when it is contractually obliged or where there is a past practice that has created a present obligation. (e) 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 experience adjustments, and changes in actuarial assumptions, are charged or credited to earnings in the period of change. These obligations are valued annually with the assistance of independent qualified actuaries. (f) Share-based compensation The Company grants unvested stock awards to senior executives and selected employees for services. The awards granted to employees vest over a three-year service period. For certain employees, awards contingently vest upon achieving certain performance conditions. The Company measures the cost of the awards based on the grant-date fair value of the awards, 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 on the shares during the requisite service period. That cost is recognized using graded vesting over the period during which an employee is required to provide service in exchange for the award or the requisite service period. Compensation is recognized only for the awards that ultimately vest. The compensation cost is recorded through earnings against equity, under “Capital surplus” in the consolidated statements of equity. The compensation cost is calculated based on the number of awards expected to vest, which includes assumptions on the number of awards to be forfeited due to the employees’ failing to fulfill the service condition, and forfeitures following the non-completion 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 at vesting date.
Share capital	2.16 – 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 or options are shown in equity as a deduction, net of tax, from the proceeds. 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 equity attributable to the Company’s shareholders until the shares are cancelled, reissued or disposed of.
Comprehensive income (loss)	2.17 – 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 stockholders and distributions to stockholders. In the accompanying consolidated financial statements, “Other comprehensive income (loss)” and “Accumulated other comprehensive income” primarily consists of foreign currency translation adjustments, temporary unrealized gains (losses) on securities classified as available-for-sale,
Revenue Recognition	2.18 – Revenue Recognition Revenue is recognized as follows: Net sales Revenue from products sold to customers is recognized when all the following conditions have been met: (a) persuasive evidence of an arrangement exists; (b) delivery has occurred; (c) the selling price is fixed or determinable; and (d) collection is reasonably assured. Revenue recognition usually occurs at the time of shipment. 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 declines in market prices. The Company accrues a provision for price protection based on a rolling historical price trend computed on a monthly basis 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 if required, to accommodate a significant change in the current market price. The short outstanding inventory time period, 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’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 end-user 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 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 elements or terms and conditions, which require judgment. Where multiple elements exist in an arrangement, the arrangement consideration is allocated to the different elements based on their respective selling price determined using vendor-specific objective evidence, third party evidence or management’s best estimate of the selling price of the separable deliverables and the applicable revenue recognition criteria are applied to each of the separate elements. These arrangements generally do not include performance-, cancellation-, termination- or refund-type provisions. Other revenues Other revenues consist of license revenue, service revenue related to transferring licenses, patent royalty income, sale of scrap materials and manufacturing by-products. Funding The Company receives funding mainly from governmental agencies and income is recognized when all contractual conditions for receipt of these funds are fulfilled. The Company’s primary sources for government funding are French, Italian and other European Union (“EU”) governmental entities. Such funding is generally provided to encourage research and development activities, industrialization and local economic development. The conditions for receipt of government funding may include eligibility restrictions, approval by EU authorities, annual budget appropriations, compliance with European Commission regulations, as well as specifications regarding objectives and results. Certain specific contracts contain obligations to maintain a minimum level of employment and investment during a certain period of time. There could be penalties if these objectives are not fulfilled. Other contracts contain penalties for late deliveries or 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 three general categories: funding for research and development activities, capital investment, and loans. Funding for research and development activities is the most common form of funding that the Company receives. Public funding for research and development is recorded as “Other income and expenses, net” in the Company’s consolidated statements of income. Public funding for research and development 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. Furthermore, French research tax credits (“Crédit Impôt Recherche”) are deemed to be grants in substance. The research tax credits are to be paid in cash by the French tax authorities within three years in case they are not deducted from income tax payable during this period of time. Unlike other research and development funding, the amounts to be received are determinable in advance and accruable as the funded research expenditures are made. They are thus reported as a reduction of “Research and development” in the consolidated statements of income. Capital investment funding is recorded as a reduction of “Property, plant and equipment, net” and is recognized in the Company’s consolidated statements of income according to the depreciation charges of the funded assets during their useful lives. The Company also receives capital funding in Italy, which can be recovered through the reduction of various governmental liabilities, including income taxes, value-added tax and employee-related social charges. Funding receivables are reported as non-current non-operating The Company receives certain loans, mainly related to large capital investment projects, at preferential interest rates. The Company records these loans as “Long-term debt” in the consolidated balance sheets.
Advertising costs	2.19 – Advertising costs Advertising costs are expensed as incurred and are recorded as “Selling, general and administrative” in the consolidated statements of income. Advertising expenses for 2016, 2015 and 2014 were $11 million, $9 million and $8 million, respectively.
Research and development	2.20 – 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 pre-production
Start-up and phase-out costs	2.21 – Start-up phase-out Start-up start-up six-months Start-up phase-out
Financial assets	2.22 – Financial assets The Company did not hold at December 31, 2016 and 2015 any financial assets classified as held-to-maturity available-for-sale. Purchases and sales of financial assets are recognized on the trade date – the date on which the Company commits to purchase or sell the asset. Financial assets classified as available-for-sale non-operating The fair values of quoted debt and equity 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. Trading financial assets A financial asset is classified in this category if it is a security acquired principally for the purpose of selling in the short term or if it is a derivative instrument not designated as a hedge. Financial assets in this category are classified as current assets when they are expected to be realized within twelve months of the balance sheet date. Marked-to-market non-operating Available-for-sale Available-for-sale non-derivative held-for-trading. Changes in fair value, including declines determined to be temporary, of securities classified as available-for-sale The Company assesses at each balance sheet date whether there is objective evidence that a financial asset or group of financial assets classified as available-for-sale available-for-sale non-operating When securities classified as available-for-sale non-operating
Derivative financial instruments and hedging activities	2.23 – 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 classified as trading financial assets, as described in Note 2.22. Derivative financial instruments classified as trading 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. These instruments do not qualify as hedging instruments, and are marked-to-market period-end 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 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. The criteria for designating a derivative as a hedge include the instrument’s effectiveness in risk reduction and a one-to-one 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. When a forecasted transaction is no longer expected to occur, the cumulative gain or loss that was reported in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity is immediately transferred to the consolidated statements of income within “Other income and expenses, net” if the de-designated de-designation, de-designation non-operating
Recent accounting pronouncements	2.24 – Recent accounting pronouncements (a) Accounting pronouncements adopted in 2016 Amended accounting guidance effective in 2016 had no material impact on the Company’s financial position, results of operations and disclosures. (b) Accounting pronouncements expected to impact the Company’s operations that are not yet effective and have not been adopted early by the Company In May 2014, the FASB issued the converged guidance on revenue from contracts with customers, updated in 2016 and 2017 with finalized amendments addressing implementation issues. The new guidance sets forth a single revenue accounting model, which calls for more professional judgment and includes expanded disclosures. Revenue recognition depicts the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled for these goods and services. Revenue is recognized when (or as) control of the goods and services is transferred to the customer. Even if the revenue recognition guidance is not a five-step model, the following steps can be identified in order to apply the new revenue accounting model: (i) identification of the contracts with customers; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to performance obligations; and (v) revenue recognition for each performance obligation. The new guidance will be effective for the Company’s first interim period within the annual reporting period beginning on January 1, 2018, with early adoption permitted as at January 1, 2017. The Company will adopt the new guidance when effective. The areas in which the new revenue recognition may create significant changes are: (i) changes in the timing of revenue recognition; (ii) inclusion of variable consideration in the transaction price; and (iii) allocation of the transaction price based on relative standalone selling prices. The Company is currently in the process of assessing the anticipated impact of the amended standard on existing revenue streams, contracts, transactions, and business practices. Based on procedures performed to date, we generally anticipate substantially similar performance conditions under the amended guidance, as such no material impact on the Company revenue recognition practices is expected. The guidance provides companies with alternative methods of adoption and we are in the process of determining our method of adoption, which depends in part upon our completion of the evaluation of our remaining revenue arrangements. In November 2015, the FASB modified the balance sheet classification of deferred taxes, as part of its initiatives to reduce complexity in accounting standards. The new guidance requires that deferred tax assets and liabilities be classified as non-current non-current tax-paying In January 2016, the FASB issued new guidance on the recognition and measurement of financial instruments. Changes to current practice primarily affect the accounting for investments in equity securities, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance relating to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale available-for-sale In February 2016, the FASB issued new guidance on lease accounting. As a lessee, an entity will need to recognize almost all leases on the balance sheet as a right-of-use In March 2016, the FASB issued new guidance on employee share-based payment accounting. The guidance includes multiple provisions intended to simplify accounting, which impacts income tax accounting, earnings per share, estimates relating to forfeitures and the statement of cash flows. The new guidance is effective for public companies for fiscal years beginning after December 15, 2016, including interim periods within those years. The Company will adopt the new guidance when effective and the new guidance is not expected to have a material impact on its consolidated financial statements. In June 2016, the FASB issued new guidance on measuring credit losses for financial instruments. The objective of the new guidance is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, primarily financial assets measured at amortized cost and available-for-sale In August and November 2016, the FASB issued amended guidance on clarifying the cash flow classification of certain topics in order to avoid diversity in practice. The issues addressed in August 2016 are debt prepayment or debt extinguishment costs (Issue 1); settlement of zero-coupon In January 2017, and after issuing in October 2016 a narrow-scope amendment to the consolidation guidance, the FASB revised the definition of a business. In the amended guidance, an acquisition, to be considered as a business, will have to include an input and a substantive process that together significantly contribute to the ability to create outputs. Businesses without outputs will need to have an organized workforce to qualify as a business. Additionally, the amended guidance will narrow the term “outputs”. The amended guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those years. The Company will adopt the new guidance when effective. In January 2017, the FASB simplified the accounting for goodwill impairment by removing step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value. The amended guidance is effective for public companies for annual and interim periods in fiscal years beginning after December 15, 2019, with early application permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Company will adopt the new guidance when effective.
