Segment Reporting [Abstract]
Description of business, including segment and geographic area information	1. 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, which are established along major categories of products as follows: • Analog – consisting of the following product lines: Power, Signal Chain and High Volume. • Embedded Processing – consisting of the following product lines: Connected Microcontrollers and Processors. 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 ® 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.

The revenue information is not necessarily indicative of the geographic area in which the end applications containing our products are ultimately consumed because our products tend to be shipped to the locations where our customers manufacture their products. Specifically, many of our products are shipped to our customers in China who may include these parts in the manufacture of their own end products, which they may in turn export to their customers around the world.

Accounting Policies [Abstract]
Basis of presentation and significant accounting policies and practices	2. 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) and on the same basis as the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2017, except for the effects of adopting Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) 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, or at the conclusion of a consignment process. 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 agreement, 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, at a point in time, generally upon shipment or delivery to the customer or distributor, depending upon the terms of the sales order. 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. For sales to distributors, payment is due on our standard commercial terms and is not contingent upon resale of the products. Revenue from sales of our products that is 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. Transfer of control occurs 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 amount of revenue recognized is adjusted based on allowances, which are prepared on a portfolio basis using a most likely amount methodology based In addition, we record allowances for 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 bad debts 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 shipping and handling costs in COR. The majority of our customers pay these fees directly to third parties. Earnings per share (EPS) Unvested share-based payment awards that contain non-forfeitable rights to receive dividends or dividend equivalents, such as our restricted stock units (RSUs), are considered to be participating securities and the two-class method is used for purposes of calculating EPS. Under the two-class method, a portion of Net income is allocated to these participating securities and, therefore, is excluded from the calculation of EPS allocated to common stock, as shown in the table below. Computation and reconciliation of earnings per common share are as follows (shares in millions): For Three Months Ended June 30, 2018 2017 Net Net Income Shares EPS Income Shares EPS Basic EPS: Net income $ 1,405 $ 1,056 Income allocated to RSUs (11 ) (10 ) Income allocated to common stock for basic EPS calculation $ 1,394 977 $ 1.43 $ 1,046 994 $ 1.05 Adjustment for dilutive shares: Stock compensation plans 20 21 Diluted EPS: Net income $ 1,405 $ 1,056 Income allocated to RSUs (11 ) (10 ) Income allocated to common stock for diluted EPS calculation $ 1,394 997 $ 1.40 $ 1,046 1,015 $ 1.03 For Six Months Ended June 30, 2018 2017 Net Net Income Shares EPS Income Shares EPS Basic EPS: Net income $ 2,771 $ 2,053 Income allocated to RSUs (23 ) (20 ) Income allocated to common stock for basic EPS calculation $ 2,748 980 $ 2.80 $ 2,033 996 $ 2.04 Adjustment for dilutive shares: Stock compensation plans 21 21 Diluted EPS: Net income $ 2,771 $ 2,053 Income allocated to RSUs (22 ) (20 ) Income allocated to common stock for diluted EPS calculation $ 2,749 1,001 $ 2.75 $ 2,033 1,017 $ 2.00 Potentially dilutive securities representing 5 million and 6 million shares of common stock that were outstanding during the second quarters of 2018 and 2017, and during the first six months of 2018 and 2017, respectively, were excluded from the computation of diluted earnings per common share for these periods because their effect would have been anti-dilutive. 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. 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. Fair values of financial instruments The fair values of our derivative financial instruments were not material as of June 30, 2018. 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. 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. The carrying value of our long-term debt approximates the fair value as measured using broker-dealer quotes, which are Level 2 inputs. See Note 4 for a description of fair value and the definition of Level 2 inputs. Changes in accounting standards – adopted standards for current period ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) This standard provides a single set of guidelines for revenue recognition to be used across all industries and requires additional disclosures. We adopted Accounting Standards Codification Topic 606 (ASC 606) as of January 1, 2018, using the modified retrospective transition method applied only to contracts that were not completed as of the adoption date. The reported results for 2018 reflect the application of the new accounting guidance, while the reported results for prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under ASC 605, Revenue Recognition The most significant impact from adopting the standard relates to our accounting for royalty income on licenses of intellectual property; however, the effect of such change during any individual reporting period will not materially impact our results of operations and financial position. Although royalty income is recorded within OI&E, the new revenue guidance applies to these agreements by analogy, and therefore, such agreements have been evaluated for ASC transition considerations. Under ASC 606, royalty income for our fixed-rate royalty agreements is bifurcated between two performance obligations: providing a right to use our initial patent portfolio and the right to access our future patents when those patents are developed. We have determined that the value of these agreements is allocated more heavily to the initial performance obligation. As a result, income from these agreements is recognized predominately at the time of contract execution rather than ratably over the life of the agreements, accelerating the timing of when we recognize royalty income in OI&E. The timing of revenue recognition, billings and cash collections may result in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities). These items are included in other current and non-current assets and liabilities on the Consolidated Balance Sheets. The time frame between when the customer places an order for products and when it is shipped is less than 12 months. Generally, we invoice customers for payment upon shipment or when goods are pulled from consignment inventory, which results in an unconditional right to consideration. Our contract assets are primarily related to our rights to consideration for satisfied or partially satisfied performance obligations on our royalty agreements for which payment has not been received as of the reporting date. We recognized an increase to opening retained earnings of $206 million, net of taxes, as of January 1, 2018, due to the cumulative impact of adopting ASC 606, with the impact primarily related to our fixed payment patent licensing agreements that were not completed as of the adoption date. A contract asset of $283 million and deferred tax liabilities of $55 million were recorded as of January 1, 2018, related to the transition period adjustments. Occasionally, as of the end of a reporting period, some of the performance obligations associated with contracts will have been unsatisfied or only partially satisfied. In accordance with the practical expedients available in the guidance, we do not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. Similarly, we do not disclose information for variable-rate consideration on our sales-based or usage-based royalties for our patent licenses. For royalty income from licensing our patent portfolios , income is allocated to performance obligations that have not yet been satisfied. The remaining performance obligations represent contracted income that has not yet been recognized, including amounts that will be invoiced and recognized as income in periods. As of June 30, 2018, we had $72 million of remaining performance obligations that had not yet been satisfied. We expect to recognize 22 percent of our remaining performance obligations as income over the next 12 months and the remainder thereafter. As of June 30, 2018, we had contract assets of $275 million. During the six months ended June 30, 2018, our contract assets were reduced by $8 million, due to $16 million of cash received offset by $8 million of income recognized. We incur commission expenses We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are included in SG&A. Other standards The following standards were adopted during the current period and did not have a material impact on our financial position and results of operations: ASU Description Adopted Date ASU No. 2016-01 Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities January 1, 2018 ASU No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business January 1, 2018 ASU No. 2017-05 Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets January 1, 2018 Changes in accounting standards – standards not yet adopted ASU No. 2016-02, Leases (Topic 842) This standard requires all leases that have a term of over 12 months to be recognized on the balance sheet with the liability for lease payments and the corresponding right-of-use asset initially measured at the present value of amounts expected to be paid over the term. Recognition of the costs of these leases on the income statement will be dependent upon their classification as either an operating or a financing lease. We do not expect to have any financing leases at the time of adoption. This standard will be effective for our interim and annual periods beginning January 1, 2019, and must be applied on a modified retrospective basis. In July 2018, the FASB approved an optional transition method to initially account for the impact of the adoption with a cumulative-effect adjustment to the January 1, 2019, rather than the January 1, 2017, financial statements. This will eliminate the need to restate amounts presented prior to January 1, 2019. We will adopt the standard effective January 1, 2019, and we expect to elect this optional transition method, as well as certain practical expedients permitted under the transition guidance within the standard. We are currently evaluating the potential impact of this standard on our financial position, but we do not expect it to have a material impact on our results of operations. ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments This standard requires entities to use a current lifetime expected credit loss methodology to measure impairments of certain financial assets. Using this methodology will result in earlier recognition of losses than under the current incurred loss approach, which requires waiting to recognize a loss until it is probable of having been incurred. There are other provisions within the standard that affect how impairments of other financial assets may be recorded and presented, and that expand disclosures. This standard will be effective for our interim and annual periods beginning January 1, 2020, and permits earlier application but not before periods beginning January 1, 2019. The standard will be applied using a modified retrospective approach. We are currently evaluating the potential impact of this standard, but we do not expect it to have a material impact on our financial position and results of operations. ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This standard allows a reclassification of stranded tax effects as a result of the U.S. Tax Cuts and Jobs Act (the Tax Act) from accumulated other comprehensive income to retained earnings. The provisions from this guidance are effective for interim and annual periods beginning after January 1, 2019. Early adoption is permitted. This standard should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effects of the Tax Act are recognized. We plan to adopt this standard during the interim period in which we complete our accounting for the tax effects of the enactment of the Tax Act, applying the guidance to the period of adoption. This standard will have no impact on our results of operations. We are currently evaluating the potential impact of this standard on our financial position.

Income Tax Disclosure [Abstract]
Income taxes	3. Income taxes Our Provision for income taxes was $301 million and $430 million for the second quarters of 2018 and 2017, respectively, and $488 million and $688 million for the first six months of 2018 and 2017, respectively. Our estimated annual effective tax rate is about 20 percent, which does not include discrete tax items. This differs from the 21 percent statutory corporate tax rate due to the effect of U.S. tax benefits, offset by a 2018 transitional tax effect. We have included the provisions of the Tax Act in the calculation of our estimated annual effective tax rate. The estimates could change when additional information on implementation of the provisions of the Tax Act becomes available. The Tax Act was enacted on December 22, 2017. We have not completed our accounting for the tax effects of enactment of the Tax Act. We have made reasonable estimates of the tax on indefinitely reinvested earnings and the effects on our existing deferred tax balances. This resulted in additional tax expense in 2017 of $773 million, consisting of $714 million related to the tax on indefinitely reinvested earnings and $59 million related to remeasuring our existing deferred tax balances. The tax on indefinitely reinvested earnings is based on our non-U.S. post-1986 earnings and profits that we previously deferred from U.S. income taxes. We have not yet completed our calculation of the total post-1986 earnings and profits for these non-U.S. subsidiaries. In the first quarter of 2018, we reduced the amount of income tax expense recorded for indefinitely reinvested earnings to $669 million from $714 million recorded in 2017. In the second quarter of 2018, we reduced the amount of income tax expense recorded for the effects of the Tax Act on our deferred tax balances to $50 million from $59 million recorded in 2017. These adjustments did not affect the estimated annual effective tax rate for 2018. The calculations of the tax effect of the Tax Act for both indefinitely reinvested earnings and deferred tax assets and liabilities are expected to be completed with the preparation of the U.S. 2017 tax return in the fourth quarter of 2018. Provision for income taxes is based on the following: For Three Months Ended For Six Months Ended June 30, June 30, 2018 2017 2018 2017 Taxes calculated using the estimated annual effective tax rate $ 344 $ 458 $ 660 $ 840 Discrete tax items (43 ) (28 ) (172 ) (152 ) Provision for income taxes $ 301 $ 430 $ 488 $ 688 Estimated annual effective tax rate 20 % 31 % 20 % 31 % Actual effective tax rate 18 % 29 % 15 % 25 %

Fair Value Disclosures [Abstract]
Valuation of debt and equity investments and certain liabilities	4. Valuation of debt and equity investments and certain liabilities Debt and equity investments We classify our investments as available for sale, trading, equity method or non-marketable equity. Most of our investments are debt securities, which are classified as available for sale. Available-for-sale and trading securities are stated at fair value, which is generally based on market prices or broker quotes. See Fair-value considerations We classify certain mutual funds as trading securities. These 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. Our other investments include equity-method investments and non-marketable equity investments, which are not measured at fair value.

Gross realized gains and losses from these sales were not material. The following table presents the aggregate maturities of our available-for-sale investments as of June 30, 2018: Due Fair Value One year or less $ 4,892 One to two years 75 Other-than-temporary declines and impairments in the values of our available-for-sale investments, which were recognized in OI&E, were not material in the first six months of 2018 and 2017 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 discussed 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 June 30, 2018 and December 31, 2017 , we had no Level 3 assets or liabilities, other than certain assets held by our postretirement plans. 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.

Debt Disclosure [Abstract]
Debt and lines of credit	7. Debt and lines of credit Short-term borrowings We maintain a line of credit to support commercial paper borrowings, if any, and to provide additional liquidity through bank loans. As of June 30, 2018, we had a variable-rate revolving credit facility from a consortium of investment-grade banks that allows us to borrow up to $2 billion until March 2023. The interest rate on borrowings under this credit facility, if drawn, is indexed to the applicable London Interbank Offered Rate (LIBOR). As of June 30, 2018, our credit facility was undrawn, and we had no commercial paper outstanding. Long-term debt We retired $500 million of maturing debt in May 2018. In the second quarter of 2018, we issued an aggregate principal amount of $1.5 billion of fixed-rate, long-term debt due in 2048, comprised of the issuance of $1.3 billion in May 2018 and an additional $200 million in June 2018. We incurred $16 million of issuance and other related costs. We received $1.5 billion in proceeds, net of the original issuance discount and premium, to be used for general corporate purposes.

Commitments And Contingencies Disclosure [Abstract]
Contingencies	8. Contingencies 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. 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) and on the same basis as the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2017, except for the effects of adopting Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606)
Revenue recognition	Revenue recognition We generate revenue primarily from the sale of semiconductor products, either directly to a customer or to a distributor, or at the conclusion of a consignment process. 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 agreement, 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, at a point in time, generally upon shipment or delivery to the customer or distributor, depending upon the terms of the sales order. 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. For sales to distributors, payment is due on our standard commercial terms and is not contingent upon resale of the products. Revenue from sales of our products that is 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. Transfer of control occurs 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 amount of revenue recognized is adjusted based on allowances, which are prepared on a portfolio basis using a most likely amount methodology based In addition, we record allowances for 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 bad debts 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 shipping and handling costs in COR. The majority of our customers pay these fees directly to third parties.
Earnings per share (EPS)	Earnings per share (EPS) Unvested share-based payment awards that contain non-forfeitable rights to receive dividends or dividend equivalents, such as our restricted stock units (RSUs), are considered to be participating securities and the two-class method is used for purposes of calculating EPS. Under the two-class method, a portion of Net income is allocated to these participating securities and, therefore, is excluded from the calculation of EPS allocated to common stock, as shown in the table below.
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. 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.
Fair values of financial instruments	Fair values of financial instruments The fair values of our derivative financial instruments were not material as of June 30, 2018. 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. 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. The carrying value of our long-term debt approximates the fair value as measured using broker-dealer quotes, which are Level 2 inputs. See Note 4 for a description of fair value and the definition of Level 2 inputs. 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 discussed 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 June 30, 2018 and December 31, 2017 , we had no Level 3 assets or liabilities, other than certain assets held by our postretirement plans.
Changes in accounting standards	Changes in accounting standards – adopted standards for current period ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) This standard provides a single set of guidelines for revenue recognition to be used across all industries and requires additional disclosures. We adopted Accounting Standards Codification Topic 606 (ASC 606) as of January 1, 2018, using the modified retrospective transition method applied only to contracts that were not completed as of the adoption date. The reported results for 2018 reflect the application of the new accounting guidance, while the reported results for prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under ASC 605, Revenue Recognition The most significant impact from adopting the standard relates to our accounting for royalty income on licenses of intellectual property; however, the effect of such change during any individual reporting period will not materially impact our results of operations and financial position. Although royalty income is recorded within OI&E, the new revenue guidance applies to these agreements by analogy, and therefore, such agreements have been evaluated for ASC transition considerations. Under ASC 606, royalty income for our fixed-rate royalty agreements is bifurcated between two performance obligations: providing a right to use our initial patent portfolio and the right to access our future patents when those patents are developed. We have determined that the value of these agreements is allocated more heavily to the initial performance obligation. As a result, income from these agreements is recognized predominately at the time of contract execution rather than ratably over the life of the agreements, accelerating the timing of when we recognize royalty income in OI&E. The timing of revenue recognition, billings and cash collections may result in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities). These items are included in other current and non-current assets and liabilities on the Consolidated Balance Sheets. The time frame between when the customer places an order for products and when it is shipped is less than 12 months. Generally, we invoice customers for payment upon shipment or when goods are pulled from consignment inventory, which results in an unconditional right to consideration. Our contract assets are primarily related to our rights to consideration for satisfied or partially satisfied performance obligations on our royalty agreements for which payment has not been received as of the reporting date. We recognized an increase to opening retained earnings of $206 million, net of taxes, as of January 1, 2018, due to the cumulative impact of adopting ASC 606, with the impact primarily related to our fixed payment patent licensing agreements that were not completed as of the adoption date. A contract asset of $283 million and deferred tax liabilities of $55 million were recorded as of January 1, 2018, related to the transition period adjustments. Occasionally, as of the end of a reporting period, some of the performance obligations associated with contracts will have been unsatisfied or only partially satisfied. In accordance with the practical expedients available in the guidance, we do not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. Similarly, we do not disclose information for variable-rate consideration on our sales-based or usage-based royalties for our patent licenses. For royalty income from licensing our patent portfolios , income is allocated to performance obligations that have not yet been satisfied. The remaining performance obligations represent contracted income that has not yet been recognized, including amounts that will be invoiced and recognized as income in periods. As of June 30, 2018, we had $72 million of remaining performance obligations that had not yet been satisfied. We expect to recognize 22 percent of our remaining performance obligations as income over the next 12 months and the remainder thereafter. As of June 30, 2018, we had contract assets of $275 million. During the six months ended June 30, 2018, our contract assets were reduced by $8 million, due to $16 million of cash received offset by $8 million of income recognized. We incur commission expenses We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are included in SG&A. Other standards The following standards were adopted during the current period and did not have a material impact on our financial position and results of operations: ASU Description Adopted Date ASU No. 2016-01 Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities January 1, 2018 ASU No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business January 1, 2018 ASU No. 2017-05 Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets January 1, 2018 Changes in accounting standards – standards not yet adopted ASU No. 2016-02, Leases (Topic 842) This standard requires all leases that have a term of over 12 months to be recognized on the balance sheet with the liability for lease payments and the corresponding right-of-use asset initially measured at the present value of amounts expected to be paid over the term. Recognition of the costs of these leases on the income statement will be dependent upon their classification as either an operating or a financing lease. We do not expect to have any financing leases at the time of adoption. This standard will be effective for our interim and annual periods beginning January 1, 2019, and must be applied on a modified retrospective basis. In July 2018, the FASB approved an optional transition method to initially account for the impact of the adoption with a cumulative-effect adjustment to the January 1, 2019, rather than the January 1, 2017, financial statements. This will eliminate the need to restate amounts presented prior to January 1, 2019. We will adopt the standard effective January 1, 2019, and we expect to elect this optional transition method, as well as certain practical expedients permitted under the transition guidance within the standard. We are currently evaluating the potential impact of this standard on our financial position, but we do not expect it to have a material impact on our results of operations. ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments This standard requires entities to use a current lifetime expected credit loss methodology to measure impairments of certain financial assets. Using this methodology will result in earlier recognition of losses than under the current incurred loss approach, which requires waiting to recognize a loss until it is probable of having been incurred. There are other provisions within the standard that affect how impairments of other financial assets may be recorded and presented, and that expand disclosures. This standard will be effective for our interim and annual periods beginning January 1, 2020, and permits earlier application but not before periods beginning January 1, 2019. The standard will be applied using a modified retrospective approach. We are currently evaluating the potential impact of this standard, but we do not expect it to have a material impact on our financial position and results of operations. ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This standard allows a reclassification of stranded tax effects as a result of the U.S. Tax Cuts and Jobs Act (the Tax Act) from accumulated other comprehensive income to retained earnings. The provisions from this guidance are effective for interim and annual periods beginning after January 1, 2019. Early adoption is permitted. This standard should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effects of the Tax Act are recognized. We plan to adopt this standard during the interim period in which we complete our accounting for the tax effects of the enactment of the Tax Act, applying the guidance to the period of adoption. This standard will have no impact on our results of operations. We are currently evaluating the potential impact of this standard on our financial position.
Debt and equity investments	Debt and equity investments We classify our investments as available for sale, trading, equity method or non-marketable equity. Most of our investments are debt securities, which are classified as available for sale. Available-for-sale and trading securities are stated at fair value, which is generally based on market prices or broker quotes. See Fair-value considerations We classify certain mutual funds as trading securities. These 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. 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.
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.
