Segment Reporting [Abstract]
Description of business, including segment and geographic area information	Description of business, including segment and geographic area information We design, make and sell semiconductors to electronics designers and manufacturers all over the world. We have two reportable segments, Analog and Embedded Processing, each of which represents groups of similar products that are combined on the basis of similar design and development requirements, product characteristics, manufacturing processes and distribution channels. • Analog semiconductors change real-world signals, such as sound, temperature, pressure or images, by conditioning them, amplifying them and often converting them to a stream of digital data that can be processed by other semiconductors, such as embedded processors. Analog semiconductors are also used to manage power in all electronic equipment by converting, distributing, storing, discharging, isolating and measuring electrical energy, whether the equipment is plugged into a wall or using a battery. Our Analog segment consists of two major product lines: Power and Signal Chain. • Embedded Processing products are the digital “brains” of many types of electronic equipment. They are designed to handle specific tasks and can be optimized for various combinations of performance, power and cost, depending on the application. During 2020, we reorganized the product lines within our Analog segment to simplify our business structure into our Power and Signal Chain product lines. These changes had no effect on either our previously reported consolidated financial statements or our reportable segment results. We report the results of our remaining business activities in Other. Other includes operating segments that do not meet the quantitative thresholds for individually reportable segments and cannot be aggregated with other operating segments. Other includes DLP ® products, calculators and custom ASIC products. In Other, we also include items that are not used in evaluating the results of or in allocating resources to our segments. Examples of these items include acquisition charges (see Note 7); restructuring charges (see Note 12); and certain corporate-level items, such as litigation expenses, environmental costs, insurance settlements, and gains and losses from other activities, including asset dispositions. We allocate the remainder of our expenses associated with corporate activities to our operating segments based on specific methodologies, such as percentage of operating expenses or headcount. Our centralized manufacturing and support organizations, such as facilities, procurement and logistics, provide support to our operating segments, including those in Other. Costs incurred by these organizations, including depreciation, are charged to the segments on a per-unit basis. Consequently, depreciation expense is not an independently identifiable component within the segments’ results and, therefore, is not provided. With the exception of goodwill, we do not identify or allocate assets by operating segment, nor does the chief operating decision maker evaluate operating segments using discrete asset information. We have no material intersegment revenue. The accounting policies of the segments are consistent with those described in the summary of significant accounting policies and practices.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation and significant accounting policies and practices	Basis of presentation and significant accounting policies and practices Basis of presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP). The basis of these financial statements is comparable for all periods presented herein. The consolidated financial statements include the accounts of all subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in these notes, except per-share amounts, are stated in millions of U.S. dollars unless otherwise indicated. We have reclassified certain amounts in the prior periods’ financial statements to conform to the 2020 presentation. The preparation of financial statements requires the use of estimates from which final results may vary. Significant accounting policies and practices Revenue recognition We generate revenue primarily from the sale of semiconductor products, either directly to a customer or to a distributor. We have a variety of types of contracts with our customers and distributors. In determining whether a contract exists, we evaluate the terms of the arrangement, the relationship with the customer or distributor and their ability to pay. We recognize revenue from sales of our products, including sales to our distributors, when control is transferred. Control is considered transferred when title and risk of loss pass, when the customer becomes obligated to pay and, where required, when the customer has accepted the products. This transfer generally occurs at a point in time upon shipment or delivery to the customer or distributor, depending upon the terms of the sales order. Payment for sales to customers and distributors is generally due on our standard commercial terms. For sales to distributors, payment is not contingent upon resale of the products. Revenue from sales of our products that are subject to inventory consignment agreements is recognized at a point in time, when the customer or distributor pulls product from consignment inventory that we store at designated locations. Delivery and transfer of control occur at that point, when title and risk of loss transfers and the customer or distributor becomes obligated to pay for the products pulled from inventory. Until the products are pulled for use or sale by the customer or distributor, we retain control over the products’ disposition, including the right to pull back or relocate the products. The revenue recognized is adjusted based on allowances, which are prepared on a portfolio basis using a most likely amount methodology based on analysis of historical data and contractual terms. These allowances, which are not material, generally include adjustments for pricing arrangements, product returns and incentives. The length of time between invoicing and payment is not significant under any of our payment terms. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. In addition, we record an allowance for credit losses on accounts receivable that we estimate may not be collected. We monitor collectability of accounts receivable primarily through review of accounts receivable aging. When collection is at risk, we assess the impact on amounts recorded for credit losses and, if necessary, record a charge in the period such determination is made. We recognize shipping fees, if any, received from customers in revenue. We include the related shipping and handling costs in cost of revenue. The majority of our customers pay these fees directly to third parties. Advertising costs We expense advertising and other promotional costs as incurred. This expense was $28 million, $30 million and $34 million in 2020, 2019 and 2018, respectively. Income taxes We account for income taxes using an asset and liability approach. We record the amount of taxes payable or refundable for the current year and the deferred tax assets and liabilities for future tax consequences related to events that have been recognized in the financial statements or tax returns. We record a valuation allowance when it is more likely than not that some or all of the deferred tax assets will not be realized. Other assessed taxes Some transactions require us to collect taxes such as sales, value-added and excise taxes from our customers. These transactions are presented in our Consolidated Statements of Income on a net (excluded from revenue) basis. Leases We determine if an arrangement is a lease at inception. Leases are included in other long-term assets, accrued expenses and other liabilities, and other long-term liabilities on our Consolidated Balance Sheets. Lease assets represent our right to use underlying assets for the lease term, and lease liabilities represent our obligations to make lease payments over the lease term. On the commencement date, leases are evaluated for classification, and assets and liabilities are recognized based on the present value of lease payments over the lease term. We use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments. Operating lease expense is generally recognized on a straight-line basis over the lease term. Our lease values include options to extend or not to terminate the lease when it is reasonably certain that we will exercise such options. We have agreements with lease and non-lease components, which are accounted for as a single lease component. Leases with an initial lease term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Earnings per share (EPS) We use the two-class method for calculating EPS because the restricted stock units (RSUs) we grant are participating securities containing non-forfeitable rights to receive dividend equivalents. Under the two-class method, a portion of net income is allocated to RSUs and excluded from the calculation of income allocated to common stock. Computation and reconciliation of earnings per common share are as follows (shares in millions): For Years Ended December 31, 2020 2019 2018 Net Income Shares EPS Net Income Shares EPS Net Income Shares EPS Basic EPS: Net income $ 5,595 $ 5,017 $ 5,580 Income allocated to RSUs (27) (32) (43) Income allocated to common stock $ 5,568 921 $ 6.05 $ 4,985 936 $ 5.33 $ 5,537 970 $ 5.71 Dilutive effect of stock compensation plans 12 16 20 Diluted EPS: Net income $ 5,595 $ 5,017 $ 5,580 Income allocated to RSUs (27) (31) (42) Income allocated to common stock $ 5,568 933 $ 5.97 $ 4,986 952 $ 5.24 $ 5,538 990 $ 5.59 Potentially dilutive securities representing 4 million, 6 million and 4 million shares of common stock that were outstanding in 2020, 2019 and 2018 respectively, were excluded from the computation of diluted earnings per common share during these periods because their effect would have been anti-dilutive. Investments We present investments on our Consolidated Balance Sheets as cash equivalents, short-term investments or long-term investments, which are detailed below. See Note 6 for additional information. • Cash equivalents and short-term investments – We consider investments in available-for-sale debt securities with maturities of 90 days or less from the date of our investment to be cash equivalents. We consider investments in available-for-sale debt securities with maturities beyond 90 days from the date of our investment as being available for use in current operations and include them in short-term investments. The primary objectives of our cash equivalent and short-term investment activities are to preserve capital and maintain liquidity while generating appropriate returns. • Long-term investments – Long-term investments consist of mutual funds, venture capital funds and non-marketable equity securities. Inventories Inventories are stated at the lower of cost or estimated net realizable value. Cost is generally computed on a currently adjusted standard cost basis, which approximates cost on a first-in, first-out basis. Standard cost is based on the normal utilization of installed factory capacity. Cost associated with underutilization of capacity is expensed as incurred. Inventory held at consignment locations is included in our finished goods inventory. We review inventory quarterly for salability and obsolescence. A statistical allowance is provided for inventory considered unlikely to be sold. The statistical allowance is based on an analysis of historical disposal activity, historical customer shipments, as well as estimated future sales. A specific allowance for each material type will be carried if there is a significant event not captured by the statistical allowance. We write off inventory in the period in which disposal occurs. Property, plant and equipment; acquisition-related intangibles; and other capitalized costs Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Our cost basis includes certain assets acquired in business combinations that were initially recorded at fair value as of the date of acquisition. Leasehold improvements are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful lives of the improvements. We amortize acquisition-related intangibles on a straight-line basis over the estimated economic life of the assets. Capitalized software licenses generally are amortized on a straight-line basis over the term of the license. Fully depreciated or amortized assets are written off against accumulated depreciation or amortization. Impairments of long-lived assets We regularly review whether facts or circumstances exist that indicate the carrying values of property, plant and equipment or other long-lived assets, including intangible assets, are impaired. We assess the recoverability of assets by comparing the projected undiscounted net cash flows associated with those assets to their respective carrying amounts. Any impairment charge is based on the excess of the carrying amount over the fair value of those assets. Fair value is determined by available market valuations, if applicable, or by discounted cash flows. Goodwill Goodwill is reviewed for impairment annually or more frequently if certain impairment indicators arise. We perform our annual goodwill impairment test as of October 1 for our reporting units, which compares the fair value for each reporting unit to its associated carrying value, including goodwill. See Note 7 for additional information. Foreign currency The functional currency for our non-U.S. subsidiaries is the U.S. dollar. Accounts recorded in currencies other than the U.S. dollar are remeasured into the functional currency. Current assets (except inventories), deferred taxes, other assets, current liabilities and long-term liabilities are remeasured at exchange rates in effect at the end of each reporting period. Property, plant and equipment with associated depreciation and inventories are valued at historical exchange rates. Revenue and expense accounts other than depreciation for each month are remeasured at the appropriate daily rate of exchange. Currency exchange gains and losses from remeasurement are credited or charged to OI&E. Derivatives and hedging We use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts, which are used as economic hedges to reduce the earnings impact that exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to OI&E. We do not apply hedge accounting to our foreign currency derivative instruments. We are exposed to variability in compensation charges related to certain deferred compensation obligations to employees. We use total return swaps to economically hedge this exposure and offset the related compensation expense, recognizing changes in the value of the swaps and the related deferred compensation liabilities in SG&A. In connection with the issuance of long-term debt, we may use financial derivatives such as treasury-rate lock agreements that are recognized in AOCI and amortized over the life of the related debt. The results of these derivative transactions have not been material. We do not use derivatives for speculative or trading purposes. Changes in accounting standards – adopted standards for current period We adopted the following Accounting Standards Updates (ASU) during the current period, none of which had a material impact on our financial position or results of operations.

Stock Compensation

Stock Compensation	12 Months Ended
	Dec. 31, 2020
Share-based Payment Arrangement [Abstract]
Stock compensation	Stock compensation We have stock options outstanding to participants under long-term incentive plans. The option price per share may not be less than the fair market value of our common stock on the date of the grant. The options have a 10-year term, generally vest ratably over four years and continue to vest after the option recipient retires. We also have RSUs outstanding to participants under long-term incentive plans. Each RSU represents the right to receive one share of TI common stock, issued on the vesting date, which is generally four years after the date of grant. RSUs continue to vest after the recipient retires. Holders of RSUs receive an annual cash payment equivalent to the dividends paid on our common stock. We have options and RSUs outstanding to non-employee directors under director compensation plans. The plans generally provide for annual grants of stock options and RSUs, a one-time grant of RSUs to each new non-employee director and the issuance of TI common stock upon the distribution of stock units credited to director deferred compensation accounts. We also have an employee stock purchase plan (ESPP) under which options are offered to all eligible employees in amounts based on a percentage of the employee’s compensation, subject to a cap. Under the plan, the option price per share is 85% of the fair market value on the exercise date. Total stock compensation expense recognized is as follows: For Years Ended December 31, 2020 2019 2018 COR $ 21 $ 21 $ 25 R&D 68 66 69 SG&A 135 130 138 Total $ 224 $ 217 $ 232 These amounts include expenses related to non-qualified stock options, RSUs and stock options offered under our ESPP and are net of estimated forfeitures. We recognize compensation expense for non-qualified stock options and RSUs on a straight-line basis over the minimum service period required for vesting of the award, adjusting for estimated forfeitures based on historical activity. Awards issued to employees who are retirement eligible or nearing retirement eligibility are expensed on an accelerated basis. Options issued under our ESPP are expensed over a three-month period. Fair-value methods and assumptions We account for all awards granted under our various stock compensation plans at fair value. We estimate the fair values for non-qualified stock options using the Black-Scholes-Merton option-pricing model with the following weighted average assumptions: For Years Ended December 31, 2020 2019 2018 Weighted average grant date fair value, per share $ 25.55 $ 22.08 $ 23.20 Weighted average assumptions used: Expected volatility 26 % 26 % 23 % Expected lives (in years) 6.8 7.1 7.2 Risk-free interest rates 1.53 % 2.66 % 2.57 % Expected dividend yields 2.76 % 2.95 % 2.25 % We determine expected volatility on all options granted using available implied volatility rates. We believe that market-based measures of implied volatility are currently the best available indicators of the expected volatility used in these estimates. We determine expected lives of options based on the historical option exercise experience of our optionees using a rolling 10-year average. We believe the historical experience method is the best estimate of future exercise patterns currently available. Risk-free interest rates are determined using the implied yield currently available for zero-coupon U.S. government issues with a remaining term equal to the expected life of the options. Expected dividend yields are based on the annualized approved quarterly dividend rate and the current market price of our common stock at the time of grant. No assumption for a future dividend rate change is included unless there is an approved plan to change the dividend in the near term. The fair value per share of RSUs is determined based on the closing price of our common stock on the date of grant. Our ESPP is a discount-purchase plan and consequently the Black-Scholes-Merton option-pricing model is not used to determine the fair value per share of these awards. The fair value per share under this plan equals the amount of the discount. Long-term incentive and director compensation plans Stock option and RSU transactions under our long-term incentive and director compensation plans are as follows: Stock Options RSUs Shares Weighted Average Exercise Price per Share Shares Weighted Average Grant Date Fair Value per Share Outstanding grants, December 31, 2019 32,493,944 $ 66.57 5,897,800 $ 79.62 Granted 4,253,606 130.48 1,005,778 130.59 Stock options exercised/RSUs vested (8,392,354) 53.28 (2,034,933) 53.88 Forfeited and expired (359,919) 111.06 (157,021) 103.90 Outstanding grants, December 31, 2020 27,995,277 79.69 4,711,624 100.80 The weighted average grant date fair values per share of RSUs granted in 2020, 2019 and 2018 were $130.59, $106.58 and $110.05, respectively. In 2020, 2019 and 2018, the total grant date fair values of shares vested from RSU grants were $110 million, $125 million and $123 million, respectively. As of December 31, 2020, the number of shares remaining available for future issuance under these plans was 40,334,683.

Summarized information as of December 31, 2020, about outstanding stock options that are vested and expected to vest, as well as stock options that are currently exercisable, is as follows: Outstanding Stock Options (Fully Vested and Expected to Vest) (a) Options Exercisable Number of outstanding (shares) 27,596,705 17,221,451 Weighted average remaining contractual life (in years) 5.8 4.4 Weighted average exercise price per share $ 79.13 $ 59.33 Intrinsic value (millions of dollars) $ 2,346 $ 1,805 (a) Includes effects of expected forfeitures. Excluding the effects of expected forfeitures, the aggregate intrinsic value of stock options outstanding was $2.36 billion. As of December 31, 2020, total future compensation related to equity awards not yet recognized in our Consolidated Statements of Income was $237 million, consisting of $103 million related to unvested stock options and $134 million related to unvested RSUs. The $237 million is expected to be recognized as follows: $115 million in 2021, $77 million in 2022, $40 million in 2023 and $5 million in 2024. Employee stock purchase plan Options outstanding under the ESPP as of December 31, 2020, had an exercise price equal to 85% of the fair market value of TI common stock on the date of automatic exercise. The automatic exercise occurred on January 4, 2021, resulting in an exercise price of $137.89 per share. Of the total outstanding options, none were exercisable as of December 31, 2020. ESPP transactions are as follows: Shares Exercise Price Outstanding grants, December 31, 2019 173,849 $ 110.14 Granted 714,680 108.74 Exercised (745,483) 103.48 Outstanding grants, December 31, 2020 143,046 137.89 The weighted average grant date fair values per share of options granted under the ESPP in 2020, 2019 and 2018 were $19.19, $18.05 and $15.43, respectively. In 2020, 2019 and 2018, the total intrinsic value of options exercised under these plans was $14 million, $13 million and $13 million, respectively. As of December 31, 2020, the number of shares remaining available for future issuance under this plan was 33,097,602. Effect on shares outstanding and treasury shares Treasury shares were acquired in connection with the board-authorized stock repurchase program. As of December 31, 2020, $10.63 billion of stock repurchase authorizations remain, and no expiration date has been specified. Our current practice is to issue shares of common stock from treasury shares upon exercise of stock options, distribution of director deferred compensation and vesting of RSUs.

Provisions of the U.S. Tax Cuts and Jobs Act (the Tax Act), such as the one-time tax on indefinitely reinvested earnings and the global intangible low-taxed income (GILTI) tax for years beginning in 2018, eliminate any additional U.S. taxation resulting from repatriation of earnings of non-U.S. subsidiaries to the United States. Consequently, no U.S. tax provision has been made for the future remittance of these earnings. However, withholding or distribution taxes in certain non-U.S. jurisdictions will be incurred upon repatriation of available cash to the United States. A provision has been made for deferred taxes on these undistributed earnings to the extent that repatriation of the available cash to the United States is expected to result in a tax liability. As of December 31, 2020, we have no basis differences that would result in material unrecognized deferred tax liabilities. We have made an allowable policy election to account for the effects of GILTI as a component of income tax expense in the period in which the tax is incurred. The primary components of deferred tax assets and liabilities are as follows: December 31, 2020 2019 Deferred tax assets: Deferred loss and tax credit carryforwards $ 207 $ 213 Accrued expenses 180 182 Stock compensation 106 109 Inventories and related reserves 105 109 Retirement costs for defined benefit and retiree health care 44 49 Other 3 — Total deferred tax assets, before valuation allowance 645 662 Valuation allowance (179) (180) Total deferred tax assets, after valuation allowance 466 482 Deferred tax liabilities: Property, plant and equipment (116) (164) International earnings (44) (62) Acquisition-related intangibles and fair-value adjustments (40) (82) Other (13) (55) Total deferred tax liabilities (213) (363) Net deferred tax asset $ 253 $ 119 The deferred tax assets and liabilities based on tax jurisdictions are presented on our Consolidated Balance Sheets as follows: December 31, 2020 2019 Deferred tax assets $ 343 $ 197 Deferred tax liabilities (90) (78) Net deferred tax asset $ 253 $ 119 We make an ongoing assessment regarding the realization of U.S. and non-U.S. deferred tax assets. This assessment is based on our evaluation of relevant criteria, including the existence of deferred tax liabilities that can be used to absorb deferred tax assets, taxable income in prior carryback years and expectations for future taxable income. Valuation allowances decreased $1 million in 2020 and increased $8 million and $7 million in 2019 and 2018, respectively. These changes had no impact to net income in 2020, 2019 or 2018. We have no tax loss carryforwards as of December 31, 2020. Cash payments made for income taxes, net of refunds, were $720 million, $570 million and $705 million in 2020, 2019 and 2018, respectively. Uncertain tax positions We operate in a number of tax jurisdictions, and our income tax returns are subject to examination by tax authorities in those jurisdictions who may challenge any item on these tax returns. Because the matters challenged by authorities are typically complex, their ultimate outcome is uncertain. Before any benefit can be recorded in our financial statements, we must determine that it is “more likely than not” that a tax position will be sustained by the appropriate tax authorities. We recognize accrued interest related to uncertain tax positions and penalties as components of OI&E. The changes in the total amounts of uncertain tax positions are as follows: 2020 2019 2018 Balance, January 1 $ 303 $ 286 $ 300 Additions based on tax positions related to the current year 3 3 3 Additions for tax positions of prior years 35 63 1 Reductions for tax positions of prior years (249) (41) — Settlements with tax authorities — (8) (18) Expiration of the statute of limitations for assessing taxes (3) — — Balance, December 31 $ 89 $ 303 $ 286 Interest income (expense) recognized in the year ended December 31 $ 39 $ 9 $ (15) Interest payable as of December 31 $ 8 $ 44 $ 49 The liability for uncertain tax positions is a component of other long-term liabilities on our Consolidated Balance Sheets. All of the $89 million and $303 million liabilities for uncertain tax positions as of December 31, 2020 and 2019, respectively, are comprised of positions that, if recognized, would lower the effective tax rate. If these liabilities are ultimately realized, $2 million of existing deferred tax assets in both 2020 and 2019 would also be realized. Reductions for tax positions of prior years in 2020 include a $249 million tax benefit for the effective settlement of a depreciation-related uncertain tax position. Accrued interest of $46 million related to this uncertain tax position was reversed and included in OI&E. As of December 31, 2020, the statute of limitations remains open for U.S. federal tax returns for 2013 and following years. Audit activities related to our U.S. federal tax returns through 2015 have been completed except for certain pending tax treaty procedures for relief from double taxation and an Internal Revenue Service appeals process related to the 2013 through 2015 audit. The procedures for relief from double taxation pertain to U.S. federal tax returns for the years 2007 through 2012. In non-U.S. jurisdictions, the years open to audit represent the years still open under the statute of limitations. With respect to major jurisdictions outside the United States, our subsidiaries are no longer subject to income tax audits for years before 2007.

Risks and Uncertainties [Abstract]
Financial instruments and risk concentration	Financial instruments and risk concentration Financial instruments We hold derivative financial instruments such as forward foreign currency exchange contracts, the fair value of which was not material as of December 31, 2020. Our forward foreign currency exchange contracts outstanding as of December 31, 2020, had a notional value of $416 million to hedge our non-U.S. dollar net balance sheet exposures, including $147 million to sell Japanese yen, $85 million to sell euros and $82 million to sell British pounds. Our investments in cash equivalents, short-term investments and certain long-term investments, as well as our deferred compensation liabilities, are carried at fair value. Our postretirement plan assets are carried at fair value or net asset value per share. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. As of December 31, 2020, the carrying value of long-term debt, including the current portion, was $6.80 billion, and the estimated fair value was $7.78 billion. The estimated fair value is measured using broker-dealer quotes, which are Level 2 inputs. See Note 6 for a description of fair value and the definition of Level 2 inputs. Risk concentration We are subject to counterparty risks from financial institutions, customers and issuers of debt securities. Financial instruments that could subject us to concentrations of credit risk are primarily cash deposits, cash equivalents, short-term investments and accounts receivable. To manage our credit risk exposure, we place cash investments in investment-grade debt securities and limit the amount of credit exposure to any one issuer. We also limit counterparties on cash deposits and financial derivative contracts to financial institutions with investment-grade ratings. Concentrations of credit risk with respect to accounts receivable are limited due to our large number of customers and their dispersion across different industries and geographic areas. We maintain allowances for expected returns, disputes, adjustments, incentives and credit losses. These allowances are deducted from accounts receivable on our Consolidated Balance Sheets. Accounts receivable allowances changed to reflect amounts charged (credited) to operating results by $3 million, ($11) million and $11 million in 2020, 2019 and 2018, respectively. Major customer

Fair Value Disclosures [Abstract]
Valuation of debt and equity investments and certain liabilities	Valuation of debt and equity investments and certain liabilities Investments measured at fair value Available-for-sale debt investments, money market funds and mutual funds are stated at fair value, which is generally based on market prices or broker quotes. See Fair-value considerations . Unrealized gains and losses from available-for-sale debt securities are recorded as an increase or decrease, net of taxes, in AOCI on our Consolidated Balance Sheets, and any credit losses on available-for-sale debt securities are recorded as an allowance for credit losses with an offset recognized in OI&E in our Consolidated Statements of Income. Our mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in SG&A. Other investments Our other investments include equity-method investments and non-marketable equity investments, which are not measured at fair value. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity-method investments are recognized in OI&E based on our ownership share of the investee’s financial results. Non-marketable equity securities are measured at cost with adjustments for observable changes in price or impairments. Gains and losses on non-marketable equity investments are recognized in OI&E. Details of our investments are as follows: December 31, 2020 December 31, 2019 Cash and Cash Equivalents Short-Term Investments Long-Term Investments Cash and Cash Equivalents Short-Term Investments Long-Term Investments Measured at fair value: Money market funds $ 886 $ — $ — $ 1,213 $ — $ — Corporate obligations 256 407 — 174 1,216 — U.S. government agency and Treasury securities 1,340 3,054 — 604 1,734 — Mutual funds — — 18 — — 272 Total 2,482 3,461 18 1,991 2,950 272 Other measurement basis: Equity-method investments — — 27 — — 24 Non-marketable equity investments — — 4 — — 4 Cash on hand 625 — — 446 — — Total $ 3,107 $ 3,461 $ 49 $ 2,437 $ 2,950 $ 300 As of December 31, 2020 and 2019, unrealized gains and losses associated with our available-for-sale investments were not material. We did not recognize any credit losses related to available-for-sale investments in 2020, 2019 or 2018. All of our debt securities classified as available for sale as of December 31, 2020, have maturities within one year. In 2020, 2019 and 2018, the proceeds from sales, redemptions and maturities of short-term available-for-sale investments were $5.29 billion, $2.31 billion and $6.71 billion, respectively. Gross realized gains and losses from these sales were not material. In 2020, we entered into total return swaps to economically hedge the variability of certain deferred compensation obligations to employees. As a result, we received proceeds of $253 million from the sale of investments in mutual funds that were previously being utilized to offset this exposure. Fair-value considerations We measure and report certain financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level hierarchy described below indicates the extent and level of judgment used to estimate fair-value measurements. • Level 1 – Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date. • Level 2 – Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. We utilize a third-party data service to provide Level 2 valuations. We verify these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets. • Level 3 – Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions. As of December 31, 2020 and 2019, we had no Level 3 assets or liabilities. The following are our assets and liabilities that were accounted for at fair value on a recurring basis. These tables do not include cash on hand, assets held by our postretirement plans, or assets and liabilities that are measured at historical cost or any basis other than fair value.

Determination of fair value is based upon management estimates and judgment, using unobservable inputs in discounted cash flow models to calculate the fair value of each reporting unit. These unobservable inputs are considered Level 3 measurements, as described in Note 6. In 2020, 2019 and 2018, we determined no impairment was indicated.

Retirement Benefits [Abstract]
Postretirement benefit plans	Postretirement benefit plans Plan descriptions We have various employee retirement plans, including defined contribution, defined benefit and retiree health care benefit plans. For qualifying employees, we offer deferred compensation arrangements. U.S. retirement plans Our principal retirement plans in the United States are a defined contribution plan, an enhanced defined contribution plan and qualified and non-qualified defined benefit pension plans. The defined benefit plans were closed to new participants in 1997, and then current participants were allowed to make a one-time election to continue accruing a benefit in the plans or to cease accruing a benefit and instead to participate in the enhanced defined contribution plan. Both defined contribution plans offer an employer-matching savings option that allows employees to make pretax and post-tax contributions to various investment choices. Employees who elected to continue accruing a benefit in the qualified defined benefit pension plans may also participate in the defined contribution plan, where employer-matching contributions are provided for up to 2% of the employee’s annual eligible earnings. Employees who elected not to continue accruing a benefit in the defined benefit pension plans and employees hired after November 1997 and through December 31, 2003, may participate in the enhanced defined contribution plan. This plan provides for a fixed employer contribution of 2% of the employee’s annual eligible earnings, plus an employer-matching contribution of up to 4% of the employee’s annual eligible earnings. Employees hired after December 31, 2003, do not receive the fixed employer contribution of 2% of the employee’s annual eligible earnings. As of December 31, 2020 and 2019, as a result of employees’ elections, TI’s U.S. defined contribution plans held shares of TI common stock totaling 7 million shares and 8 million shares valued at $1.12 billion and $988 million, respectively. Dividends paid on these shares in 2020 and 2019 were $27 million and $26 million, respectively. Effective April 1, 2016, the TI common stock fund was frozen to new contributions or transfers into the fund. Our aggregate expense for the U.S. defined contribution plans was $61 million in 2020, 2019 and 2018. The defined benefit pension plans include employees still accruing benefits, as well as employees and participants who no longer accrue service-related benefits, but instead, may participate in the enhanced defined contribution plan. Benefits under the qualified defined benefit pension plan are determined using a formula based on years of service and the highest five U.S. retiree health care benefit plan U.S. employees who meet eligibility requirements are offered medical coverage during retirement. We make a contribution toward the cost of those retiree medical benefits for certain retirees and their dependents. The contribution rates are based upon various factors, the most important of which are an employee’s date of hire, date of retirement, years of service and eligibility for Medicare benefits. The balance of the cost is borne by the plan’s participants. Employees hired after January 1, 2001, are responsible for the full cost of their medical benefits during retirement. Non-U.S. retirement plans We provide retirement coverage for non-U.S. employees, as required by local laws or to the extent we deem appropriate, through a number of defined benefit and defined contribution plans. Retirement benefits are generally based on an employee’s years of service and compensation. Funding requirements are determined on an individual country and plan basis and are subject to local country practices and market circumstances. As of December 31, 2020 and 2019, as a result of employees’ elections, TI’s non-U.S. defined contribution plans held TI common stock valued at $36 million and $28 million, respectively. Dividends paid on these shares of TI common stock in 2020 and 2019 were not material. Effects on our Consolidated Statements of Income and Balance Sheets Expenses related to defined benefit and retiree health care benefit plans are as follows: U.S. Defined Benefit U.S. Retiree Health Care Non-U.S. Defined Benefit 2020 2019 2018 2020 2019 2018 2020 2019 2018 Service cost $ 18 $ 18 $ 19 $ 3 $ 3 $ 5 $ 34 $ 31 $ 36 Interest cost 31 38 35 13 14 15 38 43 45 Expected return on plan assets (36) (41) (42) (12) (14) (15) (78) (86) (67) Amortization of prior service cost (credit) — — — (2) (1) (3) 1 1 (1) Recognized net actuarial loss 7 9 17 — — 2 14 29 20 Net periodic benefit costs 20 24 29 2 2 4 9 18 33 Settlement losses 16 10 23 — — — 1 3 3 Total, including other postretirement losses $ 36 $ 34 $ 52 $ 2 $ 2 $ 4 $ 10 $ 21 $ 36 All defined benefit and retiree health care benefit plan expense components other than service cost are recognized in OI&E in our Consolidated Statements of Income. Service cost is recognized within operating profit. For the U.S. qualified pension and retiree health care plans, the expected return on plan assets component of net periodic benefit cost is based upon a market-related value of assets. In accordance with U.S. GAAP, the market-related value of assets is the fair value adjusted by a smoothing technique whereby certain gains and losses are phased in over a period of three years. Changes in the benefit obligations and plan assets for defined benefit and retiree health care benefit plans are as follows: U.S. Defined Benefit U.S. Retiree Health Care Non-U.S. Defined Benefit 2020 2019 2020 2019 2020 2019 Change in plan benefit obligation Benefit obligation at beginning of year: $ 960 $ 874 $ 359 $ 361 $ 2,581 $ 2,411 Service cost 18 18 3 3 34 31 Interest cost 31 38 13 14 38 43 Participant contributions — — 13 13 7 7 Benefits paid (12) (11) (39) (41) (95) (103) Settlements (94) (66) — — (8) (12) Curtailments — — — — — (1) Actuarial loss (gain) 194 107 40 9 143 193 Plan amendments — — — — 1 — Effects of exchange rate changes — — — — 167 12 Benefit obligation at end of year $ 1,097 $ 960 $ 389 $ 359 $ 2,868 $ 2,581 Change in plan assets Fair value of plan assets at beginning of year: $ 987 $ 869 $ 356 $ 330 $ 2,661 $ 2,410 Actual return on plan assets 164 185 58 53 260 337 Employer contributions (qualified plans) — — 1 1 11 9 Employer contributions (non-qualified plans) 16 10 — — — — Participant contributions — — 13 13 7 7 Benefits paid (12) (11) (39) (41) (95) (103) Settlements (94) (66) — — (8) (12) Effects of exchange rate changes — — — — 172 13 Fair value of plan assets at end of year $ 1,061 $ 987 $ 389 $ 356 $ 3,008 $ 2,661 Funded status at end of year $ (36) $ 27 $ — $ (3) $ 140 $ 80 The actuarial loss (gain) for all pension plans was primarily related to a change in the discount rate used to measure the benefit obligations of those plans in 2020 and 2019. Amounts recognized on our Consolidated Balance Sheets as of December 31, are as follows: U.S. Defined Benefit U.S. Retiree Health Care Non-U.S. Defined Benefit Total 2020 Overfunded retirement plans $ 9 $ 3 $ 234 $ 246 Accrued expenses and other liabilities & other long-term liabilities (6) — (5) (11) Underfunded retirement plans (39) (3) (89) (131) Funded status at end of 2020 $ (36) $ — $ 140 $ 104 2019 Overfunded retirement plans $ 73 $ — $ 145 $ 218 Accrued expenses and other liabilities & other long-term liabilities (17) — (4) (21) Underfunded retirement plans (29) (3) (61) (93) Funded status at end of 2019 $ 27 $ (3) $ 80 $ 104 Contributions to the plans meet or exceed all minimum funding requirements. We expect to contribute about $10 million to our retirement benefit plans in 2021. Accumulated benefit obligations, which are generally less than the projected benefit obligations as they exclude the impact of future salary increases, were $992 million and $878 million as of December 31, 2020 and 2019, respectively, for the U.S. defined benefit plans, and $2.72 billion and $2.46 billion as of December 31, 2020 and 2019, respectively, for the non-U.S. defined benefit plans.

The investments in our major benefit plans largely consist of low-cost, broad-market index funds to mitigate risks of concentration within market sectors. Our investment policy is designed to better match the interest rate sensitivity of the plan assets and liabilities. The appropriate mix of equity and bond investments is determined primarily through the use of detailed asset-liability modeling studies that look to balance the impact of changes in the discount rate against the need to provide asset growth to cover future service cost. Most of our plans around the world have a greater proportion of fixed income securities with return characteristics that are more closely aligned with changes in the liabilities caused by discount rate volatility. Assumptions and investment policies U.S. Defined Benefit U.S. Retiree Health Care Non-U.S. Defined Benefit 2020 2019 2020 2019 2020 2019 Weighted average assumptions used to determine benefit obligations: Discount rate 2.81% 3.62% 2.74% 3.63% 1.31% 1.46% Long-term pay progression 3.70% 3.30% n/a n/a 3.15% 3.06% Weighted average assumptions used to determine net periodic benefit cost: Discount rate 3.42% 4.35% 3.63% 4.30% 1.46% 1.85% Long-term rate of return on plan assets 4.00% 4.90% 3.50% 4.40% 2.93% 3.62% Long-term pay progression 3.30% 3.30% n/a n/a 3.06% 3.03% We utilize a variety of methods to select an appropriate discount rate depending on the depth of the corporate bond market in the country in which the benefit plan operates. In the United States, we use a settlement approach whereby a portfolio of bonds is selected from the universe of actively traded high-quality U.S. corporate bonds. The selected portfolio is designed to provide cash flows sufficient to pay the plan’s expected benefit payments when due. The resulting discount rate reflects the rate of return of the selected portfolio of bonds. For our non-U.S. locations with a sufficient number of actively traded high-quality bonds, an analysis is performed in which the projected cash flows from the defined benefit plans are discounted against a yield curve constructed with an appropriate universe of high-quality corporate bonds available in each country. In this manner, a present value is developed. The discount rate selected is the single equivalent rate that produces the same present value. For countries that lack a sufficient corporate bond market, a government bond index is used to establish the discount rate. Assumptions for the expected long-term rate of return on plan assets are based on future expectations for returns for each asset class and the effect of periodic target asset allocation rebalancing. We adjust the results for the payment of reasonable expenses of the plan from plan assets. We believe our assumptions are appropriate based on the investment mix and long-term nature of the plans’ investments. Assumptions used for the non-U.S. defined benefit plans reflect the different economic environments within the various countries. The target allocation ranges for the plans that hold a substantial majority of the defined benefit assets are as follows: U.S. Defined Benefit U.S. Retiree Health Care Non-U.S. Defined Benefit Fixed income securities and cash equivalents 65% – 80% 65% – 80% 60% – 100% Equity securities 20% – 35% 20% – 35% 0% – 40% We rebalance the plans’ investments when they are outside the target allocation ranges. Weighted average asset allocations as of December 31 are as follows: U.S. Defined Benefit U.S. Retiree Health Care Non-U.S. Defined Benefit 2020 2019 2020 2019 2020 2019 Fixed income securities and cash equivalents 70% 65% 65% 65% 76% 73% Equity securities 30% 35% 35% 35% 24% 27% None of the plan assets related to the defined benefit pension plans and retiree health care benefit plan are directly invested in TI common stock. The following assumed future benefit payments to plan participants in the next 10 years are used to measure our benefit obligations. Almost all of the payments, which may vary significantly from these assumptions, will be made from plan assets and not from company assets. 2021 2022 2023 2024 2025 2026 – 2030 U.S. Defined Benefit $ 95 $ 137 $ 102 $ 100 $ 102 $ 490 U.S. Retiree Health Care 29 28 27 26 25 113 Non-U.S. Defined Benefit 99 102 102 105 106 558 Assumed health care cost trend rates for the U.S. retiree health care benefit plan as of December 31 are as follows: 2020 2019 Assumed health care cost trend rate for next year 6.75% 7.00% Ultimate trend rate 5.00% 5.00% Year in which ultimate trend rate is reached 2028 2028 Deferred compensation plans We have deferred compensation plans that allow U.S. employees whose base salary and management responsibility exceed a certain level to defer receipt of a portion of their cash compensation. Payments under these plans are made based on the participant’s distribution election and plan balance. Participants can earn a return on their deferred compensation based on notional investments in the same investment funds that are offered in our defined contribution plans. As of December 31, 2020, our liability to participants of the deferred compensation plans was $350 million and is recorded in other long-term liabilities on our Consolidated Balance Sheets. This amount reflects the accumulated participant deferrals and earnings thereon as of that date. We utilize total return swaps and investments in mutual funds that serve as economic hedges of our exposure to changes in the fair value of these liabilities. We record changes in the fair value of the liability and the related total return swaps and mutual funds in SG&A, as discussed in Note 6. As of December 31, 2020, we held $18 million in mutual funds related to these plans that are recorded in long-term investments on our Consolidated Balance Sheets.

Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate any future liabilities that may result. Warranty costs/product liabilities We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Our stated warranties for semiconductor products obligate us to repair, replace or credit the purchase price of a covered product back to the buyer. Product claim consideration may exceed the price of our products. General We are subject to various legal and administrative proceedings. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP). The basis of these financial statements is comparable for all periods presented herein. The consolidated financial statements include the accounts of all subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in these notes, except per-share amounts, are stated in millions of U.S. dollars unless otherwise indicated. We have reclassified certain amounts in the prior periods’ financial statements to conform to the 2020 presentation. The preparation of financial statements requires the use of estimates from which final results may vary.
Revenue recognition	Revenue recognition We generate revenue primarily from the sale of semiconductor products, either directly to a customer or to a distributor. We have a variety of types of contracts with our customers and distributors. In determining whether a contract exists, we evaluate the terms of the arrangement, the relationship with the customer or distributor and their ability to pay. We recognize revenue from sales of our products, including sales to our distributors, when control is transferred. Control is considered transferred when title and risk of loss pass, when the customer becomes obligated to pay and, where required, when the customer has accepted the products. This transfer generally occurs at a point in time upon shipment or delivery to the customer or distributor, depending upon the terms of the sales order. Payment for sales to customers and distributors is generally due on our standard commercial terms. For sales to distributors, payment is not contingent upon resale of the products. Revenue from sales of our products that are subject to inventory consignment agreements is recognized at a point in time, when the customer or distributor pulls product from consignment inventory that we store at designated locations. Delivery and transfer of control occur at that point, when title and risk of loss transfers and the customer or distributor becomes obligated to pay for the products pulled from inventory. Until the products are pulled for use or sale by the customer or distributor, we retain control over the products’ disposition, including the right to pull back or relocate the products. The revenue recognized is adjusted based on allowances, which are prepared on a portfolio basis using a most likely amount methodology based on analysis of historical data and contractual terms. These allowances, which are not material, generally include adjustments for pricing arrangements, product returns and incentives. The length of time between invoicing and payment is not significant under any of our payment terms. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. In addition, we record an allowance for credit losses on accounts receivable that we estimate may not be collected. We monitor collectability of accounts receivable primarily through review of accounts receivable aging. When collection is at risk, we assess the impact on amounts recorded for credit losses and, if necessary, record a charge in the period such determination is made. We recognize shipping fees, if any, received from customers in revenue. We include the related shipping and handling costs in cost of revenue. The majority of our customers pay these fees directly to third parties.
Advertising costs	Advertising costs We expense advertising and other promotional costs as incurred. This expense was $28 million, $30 million and $34 million in 2020, 2019 and 2018, respectively.
Income taxes	Income taxes We account for income taxes using an asset and liability approach. We record the amount of taxes payable or refundable for the current year and the deferred tax assets and liabilities for future tax consequences related to events that have been recognized in the financial statements or tax returns. We record a valuation allowance when it is more likely than not that some or all of the deferred tax assets will not be realized.
Other assessed taxes	Other assessed taxes Some transactions require us to collect taxes such as sales, value-added and excise taxes from our customers. These transactions are presented in our Consolidated Statements of Income on a net (excluded from revenue) basis.
Leases	Leases We determine if an arrangement is a lease at inception. Leases are included in other long-term assets, accrued expenses and other liabilities, and other long-term liabilities on our Consolidated Balance Sheets. Lease assets represent our right to use underlying assets for the lease term, and lease liabilities represent our obligations to make lease payments over the lease term. On the commencement date, leases are evaluated for classification, and assets and liabilities are recognized based on the present value of lease payments over the lease term. We use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments. Operating lease expense is generally recognized on a straight-line basis over the lease term. Our lease values include options to extend or not to terminate the lease when it is reasonably certain that we will exercise such options. We have agreements with lease and non-lease components, which are accounted for as a single lease component. Leases with an initial lease term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.
Earnings per share (EPS)	Earnings per share (EPS) We use the two-class method for calculating EPS because the restricted stock units (RSUs) we grant are participating securities containing non-forfeitable rights to receive dividend equivalents. Under the two-class method, a portion of net income is allocated to RSUs and excluded from the calculation of income allocated to common stock.
Investments	Investments We present investments on our Consolidated Balance Sheets as cash equivalents, short-term investments or long-term investments, which are detailed below. See Note 6 for additional information. • Cash equivalents and short-term investments – We consider investments in available-for-sale debt securities with maturities of 90 days or less from the date of our investment to be cash equivalents. We consider investments in available-for-sale debt securities with maturities beyond 90 days from the date of our investment as being available for use in current operations and include them in short-term investments. The primary objectives of our cash equivalent and short-term investment activities are to preserve capital and maintain liquidity while generating appropriate returns. • Long-term investments – Long-term investments consist of mutual funds, venture capital funds and non-marketable equity securities. Investments measured at fair value Available-for-sale debt investments, money market funds and mutual funds are stated at fair value, which is generally based on market prices or broker quotes. See Fair-value considerations . Unrealized gains and losses from available-for-sale debt securities are recorded as an increase or decrease, net of taxes, in AOCI on our Consolidated Balance Sheets, and any credit losses on available-for-sale debt securities are recorded as an allowance for credit losses with an offset recognized in OI&E in our Consolidated Statements of Income. Our mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in SG&A. Other investments Our other investments include equity-method investments and non-marketable equity investments, which are not measured at fair value. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity-method investments are recognized in OI&E based on our ownership share of the investee’s financial results. Non-marketable equity securities are measured at cost with adjustments for observable changes in price or impairments. Gains and losses on non-marketable equity investments are recognized in OI&E.
Inventories	Inventories Inventories are stated at the lower of cost or estimated net realizable value. Cost is generally computed on a currently adjusted standard cost basis, which approximates cost on a first-in, first-out basis. Standard cost is based on the normal utilization of installed factory capacity. Cost associated with underutilization of capacity is expensed as incurred. Inventory held at consignment locations is included in our finished goods inventory. We review inventory quarterly for salability and obsolescence. A statistical allowance is provided for inventory considered unlikely to be sold. The statistical allowance is based on an analysis of historical disposal activity, historical customer shipments, as well as estimated future sales. A specific allowance for each material type will be carried if there is a significant event not captured by the statistical allowance. We write off inventory in the period in which disposal occurs.
Property, plant and equipment; acquisition-related intangibles and other capitalized costs	Property, plant and equipment; acquisition-related intangibles; and other capitalized costs Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Our cost basis includes certain assets acquired in business combinations that were initially recorded at fair value as of the date of acquisition. Leasehold improvements are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful lives of the improvements. We amortize acquisition-related intangibles on a straight-line basis over the estimated economic life of the assets. Capitalized software licenses generally are amortized on a straight-line basis over the term of the license. Fully depreciated or amortized assets are written off against accumulated depreciation or amortization.
Impairments of long-lived assets	Impairments of long-lived assets We regularly review whether facts or circumstances exist that indicate the carrying values of property, plant and equipment or other long-lived assets, including intangible assets, are impaired. We assess the recoverability of assets by comparing the projected undiscounted net cash flows associated with those assets to their respective carrying amounts. Any impairment charge is based on the excess of the carrying amount over the fair value of those assets. Fair value is determined by available market valuations, if applicable, or by discounted cash flows.
Goodwill	Goodwill Goodwill is reviewed for impairment annually or more frequently if certain impairment indicators arise. We perform our annual goodwill impairment test as of October 1 for our reporting units, which compares the fair value for each reporting unit to its associated carrying value, including goodwill. See Note 7 for additional information.
Foreign currency	Foreign currency The functional currency for our non-U.S. subsidiaries is the U.S. dollar. Accounts recorded in currencies other than the U.S. dollar are remeasured into the functional currency. Current assets (except inventories), deferred taxes, other assets, current liabilities and long-term liabilities are remeasured at exchange rates in effect at the end of each reporting period. Property, plant and equipment with associated depreciation and inventories are valued at historical exchange rates. Revenue and expense accounts other than depreciation for each month are remeasured at the appropriate daily rate of exchange. Currency exchange gains and losses from remeasurement are credited or charged to OI&E.
Derivatives and hedging	Derivatives and hedging We use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts, which are used as economic hedges to reduce the earnings impact that exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to OI&E. We do not apply hedge accounting to our foreign currency derivative instruments. We are exposed to variability in compensation charges related to certain deferred compensation obligations to employees. We use total return swaps to economically hedge this exposure and offset the related compensation expense, recognizing changes in the value of the swaps and the related deferred compensation liabilities in SG&A. In connection with the issuance of long-term debt, we may use financial derivatives such as treasury-rate lock agreements that are recognized in AOCI and amortized over the life of the related debt. The results of these derivative transactions have not been material. We do not use derivatives for speculative or trading purposes.
Changes in accounting standards	Changes in accounting standards – adopted standards for current period We adopted the following Accounting Standards Updates (ASU) during the current period, none of which had a material impact on our financial position or results of operations. ASU Description Adopted Date ASU No. 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments January 1, 2020 ASU No. 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement January 1, 2020 ASU No. 2018-15 Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract January 1, 2020
Stock compensation	We recognize compensation expense for non-qualified stock options and RSUs on a straight-line basis over the minimum service period required for vesting of the award, adjusting for estimated forfeitures based on historical activity. Awards issued to employees who are retirement eligible or nearing retirement eligibility are expensed on an accelerated basis. Options issued under our ESPP are expensed over a three-month period. We determine expected volatility on all options granted using available implied volatility rates. We believe that market-based measures of implied volatility are currently the best available indicators of the expected volatility used in these estimates. We determine expected lives of options based on the historical option exercise experience of our optionees using a rolling 10-year average. We believe the historical experience method is the best estimate of future exercise patterns currently available. Risk-free interest rates are determined using the implied yield currently available for zero-coupon U.S. government issues with a remaining term equal to the expected life of the options. Expected dividend yields are based on the annualized approved quarterly dividend rate and the current market price of our common stock at the time of grant. No assumption for a future dividend rate change is included unless there is an approved plan to change the dividend in the near term. The fair value per share of RSUs is determined based on the closing price of our common stock on the date of grant. Our ESPP is a discount-purchase plan and consequently the Black-Scholes-Merton option-pricing model is not used to determine the fair value per share of these awards. The fair value per share under this plan equals the amount of the discount.
Fair values considerations	Fair-value considerations We measure and report certain financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level hierarchy described below indicates the extent and level of judgment used to estimate fair-value measurements. • Level 1 – Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date. • Level 2 – Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. We utilize a third-party data service to provide Level 2 valuations. We verify these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets. • Level 3 – Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions. As of December 31, 2020 and 2019, we had no Level 3 assets or liabilities.
Indemnification guarantees and warranty costs/product liabilities	Indemnification guarantees We routinely sell products with an intellectual property indemnification included in the terms of sale. Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate any future liabilities that may result. Warranty costs/product liabilities We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Our stated warranties for semiconductor products obligate us to repair, replace or credit the purchase price of a covered product back to the buyer. Product claim consideration may exceed the price of our products.
