Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation These statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”) and, in accordance with those rules and regulations, do not include all information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the results of operations, financial position and cash flows of Teradata Corporation (“Teradata” or the “Company”) for the interim periods presented herein. The year-end 2018 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make use of estimates and assumptions that affect the reported amounts and disclosures. Actual results may vary from these estimates. These condensed consolidated interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in Teradata’s most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the “ 2018 Annual Report”). The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the full year. Prior period amounts have been restated to conform to the current year presentation, except for lease accounting discussed in Notes 2 and 12.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Fair Value Measurement. In August 2018, the Financial Accounting Standards Board ("FASB") issued new guidance that modifies disclosure requirements related to fair value measurement. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this update while delaying adoption of the additional disclosures until their effective date. The Company is currently evaluating this guidance to determine the impact it may have on its disclosures. Compensation-Retirement Benefits-Defined Benefit Plans-General . In August 2018, the FASB issued new guidance that modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. For public companies, the amendments in this update are effective for fiscal years beginning after December 15, 2020, with early adoption permitted, and is to be applied on a retrospective basis to all periods presented. The Company is currently evaluating this guidance to determine the impact it may have on its disclosures. Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. In August 2018, the FASB issued new guidance that reduces complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). For public companies, the amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Implementation should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The effects of this standard on our financial position, results of operations or cash flows are not expected to be material. Codification Improvements to Financial Instruments-Credit Losses, Derivatives and Hedging, and Financial Instruments. In June 2016, the FASB issued Accounting Standards, Measurement of Credit Losses on Financial Instruments, which introduced the expected credit losses methodology for the measurement of credit losses on financial assets measured at amortized cost basis, replacing the previous incurred loss methodology. Since the issuance of this accounting standard, the Board has identified certain areas that require clarification and improvement. In May 2019, the FASB issued guidance that allows entities to make an irrevocable one-time election upon adoption of the new credit losses standard to measure financial assets measured at amortized cost (except held-to-maturity securities) using the fair value option. The election is to be applied on an instrument-by-instrument basis. For entities that have already adopted the new credit losses standard, the relief is effective for fiscal years beginning after December 15, 2019 and interim periods therein, and early adoption is permitted. For all other entities, the guidance is effective upon adoption of the new credit losses standard. The company is currently evaluating this new guidance to determine the impact it may have on our financial position, results of operations or cash flows. Recently Adopted Guidance Leases. In February 2016, the FASB issued new guidance under Topic 842, which requires a lessee to account for leases as finance or operating leases. Both types of leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability on its balance sheet, with differing methodology for income statement and cash flow recognition. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. Entities will classify leases to determine how to recognize lease-related revenue and expense. We adopted the new standard as of January 1, 2019 using the modified retrospective adoption approach utilizing the optional transition method with prior periods not recast and have elected certain of the practical expedients allowed under the standard. The Condensed Consolidated Financial Statements for the three and six months ended June 30, 2019 are presented under the new standard, while comparative years presented are not adjusted and continue to be reported in accordance with our historical accounting policy. See Note 12 for more information. Comprehensive Income. In February 2018, the FASB issued new guidance for Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02), which allows companies to reclassify stranded tax effects resulting from the Tax Reform Act from accumulated other comprehensive income to retained earnings. The impact of applying this standard did not have a material impact on our condensed consolidated financial statements. Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made. In June 2018, the FASB issued new guidance to clarify and improve the scope and the accounting guidance for contributions received and contributions made. The amendments are intended to assist entities in evaluating whether transactions should be accounted for as contributions (nonreciprocal transactions) or as exchange (reciprocal) transactions and determining whether a contribution is conditional. The Company adopted this guidance on January 1, 2019, which did not have a material impact on our condensed consolidated financial statements.

Accounts receivable include amounts due from customers that are unconditional. Contract assets relate to the Company’s rights to consideration for goods delivered or services completed and recognized as revenue but billing and the right to receive payment is conditional upon the completion of other performance obligations. Contract assets are included in other current assets on the balance sheet and are transferred to accounts receivable when the rights become unconditional. Deferred revenue consists of advance payments and billings in excess of revenue recognized. Deferred revenue is classified as either current or noncurrent based on the timing of when the Company expects to recognize revenue. These assets and liabilities are reported on a contract-by-contract basis at the end of each reporting period. The following table provides information about receivables, contract assets and deferred revenue from contracts with customers: As of in millions June 30, 2019 December 31, 2018 Accounts receivable, net $ 377 $ 588 Contract assets $ 6 $ 14 Current deferred revenue $ 498 $ 490 Long-term deferred revenue $ 82 $ 105 Revenue recognized during the six months ended June 30, 2019 from amounts included in deferred revenue at the beginning of the period was $402 million . Transaction Price Allocated to Unsatisfied Obligations The following table includes estimated revenue expected to be recognized in the future related to the Company's unsatisfied (or partially satisfied) obligations at June 30, 2019: in millions Total at June 30, 2019 Year 1 Year 2 and Thereafter Remaining unsatisfied obligations $ 2,530 $ 1,182 $ 1,348 The amounts above represent the price of firm orders for which work has not been performed or goods have not been delivered and exclude unexercised contract options outside the stated contractual term that do not represent material rights to the customer. Although the Company believes that the contract value in the above table is firm, approximately $1,636 million of the amount includes customer-only general cancellation for convenience terms that the Company is contractually obligated to perform unless the customer notifies us. The Company expects to recognize revenue of approximately $437 million The Company capitalizes sales commissions and other contract costs that are incremental direct costs of obtaining customer contracts if the expected amortization period of the asset is greater than one year. These costs are recorded in Other Assets on the Company’s balance sheet. The capitalized amounts are calculated based on the annual recurring revenue and total contract value for individual multi-term contracts. The judgments made in determining the amount of costs incurred include whether the commissions are in fact incremental and would not have occurred absent the customer contract. Costs to obtain a contract are amortized as selling, general and administrative expenses on a straight-line basis over the expected period of benefit, which is typically around four years . These costs are periodically reviewed for impairment.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax provisions for interim periods are based on estimated annual income tax rates, adjusted to reflect the effects of any significant infrequent or unusual items which are required to be discretely recognized within the current interim period. As a result of the Tax Cuts and Jobs Act of 2017 (the "2017 Tax Act”), the Company changed its indefinite reversal assertion related to its undistributed earnings of its foreign subsidiaries and no longer considers a majority of its foreign earnings permanently reinvested outside of the United States ("U.S."). As a result, the effective tax rates in the periods presented are largely based upon the forecasted pre-tax earnings mix and allocation of certain expenses in various taxing jurisdictions where the Company conducts its business. The effective tax rate is as follows: Three Months Ended June 30, Six Months Ended June 30, In millions 2019 2018 2019 2018 Effective tax rate 120.0 % 33.3 % (120.0 )% (50.0 )% For the three months and six months ended June 30, 2019 , a $4 million discrete tax item was recorded related to an uncertain tax position resulting from the reversal of the Tax Court’s decision in the Altera case by the Ninth Circuit Court of Appeals on June 7, 2019. The Altera case focused on whether current U.S. Treasury Regulations requiring the inclusion of stock-based compensation expense in a taxpayer's cost-sharing calculations are valid. As a result of this discrete item and incremental tax expense related to equity compensation, the Company recorded income tax expense of $6 million on a pre-tax net loss of $5 million for the six months ended June 30, 2019 , resulting in an effective income tax rate of (120.0)% . There were no material discrete tax items recorded for the three or six month periods ended June 30, 2018 . Discrete tax items related to interest accruals on uncertain tax positions and equity-based compensation resulted in income tax expense of $1 million on a pre-tax net loss of $2 million for the six months ended June 30, 2018 , resulting in an effective income tax rate of (50.0)% . The Company estimates its annual effective tax rate for 2019 to be approximately 21% , which takes into consideration, among other things, the forecasted earnings mix by jurisdiction. The 2017 Tax Act subjects U.S. shareholders to a tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. The Company has elected to provide for the tax expense related to GILTI in the year the tax is incurred. The Company does not expect a material amount of tax expense related to GILTI based on our forecasted marginal effective tax rate for 2019.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities As a portion of Teradata’s operations is conducted outside the U.S. and in currencies other than the U.S. dollar, the Company is exposed to potential gains and losses from changes in foreign currency exchange rates. In an attempt to mitigate the impact of currency fluctuations, the Company uses foreign exchange forward contracts to hedge transactional exposures resulting predominantly from foreign currency denominated inter-company receivables and payables. The forward contracts are designated as fair value hedges of specified foreign currency denominated inter-company receivables and payables and generally mature in three months or less. The fair values of foreign exchange contracts are based on market spot and forward exchange rates and represent estimates of possible value that may not be realized in the future. Across its portfolio of contracts, Teradata has both long and short positions relative to the U.S. dollar. As a result, Teradata’s net involvement is less than the total contract notional amount of the Company’s foreign exchange forward contracts. Gains and losses from foreign exchange forward contracts are fully recognized each period and reported along with the offsetting gain or loss of the related hedged item, either in cost of revenues or in other income (expense), depending on the nature of the related hedged item. In June 2018, Teradata executed a five-year interest rate swap with a $500 million initial notional amount to hedge the floating interest rate of its Term Loan, as more fully described in Note 11. The Company uses interest rate swaps to manage interest rate risks on future interest payments caused by interest rate changes on its variable rate term loan facility. The notional amount of the hedge will step-down according to the amortization schedule of the term loan. The notional amount of the hedge was $494 million as of June 30, 2019. The Company performed an initial effectiveness assessment in the third quarter of 2018 on the interest rate swap and the hedge was determined to be effective. The hedge is being evaluated qualitatively on a quarterly basis for effectiveness. Changes in fair value are recorded in Accumulated Other Comprehensive Loss and periodic settlements of the swap will be recorded in interest expense along with the interest on amounts outstanding under the term loan facility. The following table identifies the contract notional amount of the Company’s derivative financial instruments: As of In millions June 30, December 31, Contract notional amount of foreign exchange forward contracts $ 156 $ 256 Net contract notional amount of foreign exchange forward contracts $ 46 $ 35 Contract notional amount of interest rate swap $ 494 $ 500 All derivatives are recognized in the condensed consolidated balance sheets at their fair value. The notional amounts represent agreed-upon amounts on which calculations of dollars to be exchanged are based and are an indication of the extent of Teradata’s involvement in such instruments. These notional amounts do not represent amounts exchanged by the parties and, therefore, are not a measure of the instruments. Refer to Note 10 for disclosures related to the fair value of all derivative assets and liabilities. The Company does not hold or issue derivative financial instruments for trading purposes, nor does it hold or issue leveraged derivative instruments. By using derivative financial instruments to hedge exposures to changes in foreign exchange and interest rates, the Company exposes itself to credit risk. The Company manages exposure to counterparty credit risk by entering into derivative financial instruments with highly rated institutions that can be expected to fully perform under the terms of the applicable contracts.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Company is subject to proceedings, lawsuits, governmental investigations, claims and other matters, including those that relate to the environment, health and safety, employee benefits, export compliance, intellectual property, tax matters and other regulatory compliance and general matters. We are not currently a party to any litigation, nor are we aware of any pending or threatened litigation against us that we believe would materially affect our business, operating results, financial condition or cash flows. Guarantees and Product Warranties. Guarantees associated with the Company’s business activities are reviewed for appropriateness and impact to the Company’s financial statements. Periodically, the Company’s customers enter into various leasing arrangements with a third-party leasing company as part of a revenue transaction, whereby the leasing company purchases the equipment from Teradata and leases it to the customer. In some instances, the Company guarantees the leasing company a minimum value at the end of the lease term on the leased equipment. As of June 30, 2019 , the maximum future payment obligation of this guaranteed value and the associated liability balance was $3 million . The Company provides its customers a standard manufacturer’s warranty and records, at the time of the sale, a corresponding estimated liability for potential warranty costs. Estimated future obligations due to warranty claims are based upon historical factors such as labor rates, average repair time, travel time, number of service calls and cost of replacement parts. For each consummated sale, the Company recognizes the total customer revenue and records the associated warranty liability under other current liabilities in the balance sheet using pre-established warranty percentages for that product class. The following table identifies the activity relating to the warranty reserve for the six months ended June 30 : In millions 2019 2018 Warranty reserve liability Beginning balance at January 1 $ 3 $ 4 Accrual of warranties issued 1 2 Settlements (in cash or in kind) (2 ) (3 ) Balance at June 30 $ 2 $ 3 The Company also offers extended and/or enhanced coverage to its customers in the form of maintenance contracts. The Company accounts for these contracts by deferring the related maintenance revenue over the extended and/or enhanced coverage period. Costs associated with maintenance support are expensed as incurred. Amounts associated with these maintenance contracts are not included in the table above. In addition, the Company provides its customers with certain indemnification rights. In general, the Company agrees to indemnify the customer if a third-party asserts patent or other infringement on the part of the customer for its use of the Company’s products. The Company has entered into indemnification agreements with the officers and directors of its subsidiaries. From time to time, the Company also enters into agreements in connection with its acquisition and divesture activities that include indemnification obligations by the Company. The fair value of these indemnification obligations is not readily determinable due to the conditional nature of the Company’s potential obligations and the specific facts and circumstances involved with each particular agreement, and as such the Company has not recorded a liability in connection with these indemnification arrangements. Historically, payments made by the Company under these types of agreements have not had a material effect on the Company’s consolidated financial condition, results of operations or cash flows. Concentrations of Risk . The Company is potentially subject to concentrations of credit risk on accounts receivable and financial instruments such as hedging instruments, and cash and cash equivalents. Credit risk includes the risk of nonperformance by counterparties. The maximum potential loss may exceed the amount recognized on the balance sheet. Exposure to credit risk is managed through credit approvals, credit limits, selecting major international financial institutions (as counterparties to hedging transactions) and monitoring procedures. Teradata’s business often involves large transactions with customers, and if one or more of those customers were to default in its obligations under applicable contractual arrangements, the Company could be exposed to potentially significant losses. However, management believes that the reserves for potential losses were adequate at June 30, 2019 and December 31, 2018 . The Company is also potentially subject to concentrations of supplier risk. Our hardware components are assembled exclusively by Flex Ltd. (“Flex”). Flex procures a wide variety of components used in the manufacturing process on behalf of the Company. Although many of these components are available from multiple sources, Teradata utilizes preferred supplier relationships to provide more consistent and optimal quality, cost and delivery. Typically, these preferred suppliers maintain alternative processes and/or facilities to ensure continuity of supply. Given the Company’s strategy to outsource its manufacturing activities to Flex and to source certain components from single suppliers, a disruption in production at Flex or at a supplier could impact the timing of customer shipments and/or Teradata’s operating results. In addition, a significant change in the forecasts to any of these preferred suppliers could result in purchase obligations for components that may be in excess of demand.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value measurements are established utilizing a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as significant other observable inputs, such as quoted prices in active markets for similar assets or liabilities, or quoted prices in less-active markets for identical assets; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assets and liabilities measured at fair value on a recurring basis include money market funds, interest rate swaps and foreign currency exchange contracts. A portion of the Company’s excess cash reserves are held in money market funds which generate interest income based on the prevailing market rates. Money market funds are included in cash and cash equivalents in the Company’s balance sheet. Money market fund holdings are measured at fair value using quoted market prices and are classified within Level 1 of the valuation hierarchy. When deemed appropriate, the Company minimizes its exposure to changes in foreign currency exchange rates through the use of derivative financial instruments, specifically, foreign exchange forward contracts. Additionally, in June 2018, Teradata executed a five-year interest rate swap with a $500 million initial notional amount in order to hedge the floating interest rate on its term-loan. The fair value of these contracts and swaps are measured at the end of each interim reporting period using observable inputs other than quoted prices, specifically market spot and forward exchange rates. As such, these derivative instruments are classified within Level 2 of the valuation hierarchy. Fair value of unrealized gains for open contracts are recorded in other assets and the fair value of unrealized losses are recorded in other liabilities in the Company's balance sheet. The fair value of foreign exchange forward contracts recorded in other assets was $1 million and the amount recorded in other liabilities was immaterial at June 30, 2019 . The amount of assets and liabilities at December 31, 2018 was not material. Realized gains and losses from the Company’s fair value hedges net of corresponding gains or losses on the underlying exposures were immaterial for the three and six months ended June 30, 2019 and 2018. The Company’s other assets and liabilities measured at fair value on a recurring basis and subject to fair value disclosure requirements at June 30, 2019 and December 31, 2018 were as follows: Fair Value Measurements at Reporting Date Using In millions Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Money market funds at June 30, 2019 $ 218 $ 218 $ — $ — Money market funds at December 31, 2018 $ 246 $ 246 $ — $ — Liabilities Interest rate swap at June 30, 2019 $ 20 $ — $ 20 $ — Interest rate swap at December 31, 2018 $ 7 $ — $ 7 $ —

Debt

Debt Disclosure [Abstract]
Debt	Debt On June 11, 2018, Teradata replaced its existing five-year, $400 million revolving credit facility with a new 400 million $400 million revolving credit facility (the “Credit Facility”). The Credit Facility ends on June 11, 2023, at which point any remaining outstanding borrowings would be due for repayment unless extended by agreement of the parties for up to two additional one-year periods. In addition, under the terms of the Revolving Credit Agreement, Teradata from time to time and subject to certain conditions may increase the lending commitments under the Revolving Credit Agreement in an aggregate principal amount up to an additional $200 million , to the extent that existing or new lenders agree to provide such additional commitments. The outstanding principal amount of the Revolving Credit Agreement bears interest at a floating rate based upon, at Teradata’s option, a negotiated base rate or a Eurodollar rate plus, in each case, a margin based on Teradata’s leverage ratio. In the near term, Teradata would anticipate choosing a floating rate based on London Interbank Offered Rate (“LIBOR”). The Credit Facility is unsecured but is guaranteed by certain of Teradata’s material domestic subsidiaries and contains certain representations and warranties, conditions, affirmative, negative and financial covenants, and events of default customary for such facilities. As of June 30, 2019, the Company had no borrowings outstanding under the Credit Facility, leaving $400 million in additional borrowing capacity available under the Credit Facility. The Company was in compliance with all covenants as of June 30, 2019. Also, on June 11, 2018, Teradata closed on a new senior unsecured $500 million five-year term loan, the proceeds of which plus additional cash-on-hand were used to pay off the remaining $525 million of principal on its existing term loan. The $500 million term loan is payable in quarterly installments, which commenced on June 30, 2019 with 1.25% of the initial principal amount due on each of the first eight payment dates; 2.50% of the initial principal amount due on each of the next four payment dates; 5.0% of the initial principal amount due on each of the next three payment dates; and all remaining principal due on June 11, 2023. The outstanding principal amount under the term loan agreement bears interest at a floating rate based upon a negotiated base rate or a Eurodollar rate plus a margin based on the leverage ratio of the Company. As of June 30, 2019 , the term loan principal outstanding was $494 million . As disclosed in Note 8, Teradata entered into an interest rate swap to hedge the floating interest rate of the Term Loan. As a result of the swap, Teradata’s fixed rate on the term loan equals 2.86% plus the applicable leverage-based margin as defined in the Term Loan agreement. As of June 30, 2019 , the all-in fixed rate is 4.36% . The Company was in compliance with all covenants as of June 30, 2019 . Teradata’s term loan is recognized on the Company’s balance sheet at its unpaid principal balance and is not subject to fair value measurement. However, given that the loan carries a variable rate, the Company estimates that the unpaid principal balance of the term loan would approximate its fair value. If measured at fair value in the financial statements, the Company’s term loan would be classified as Level 2 in the fair value hierarchy.

Leases [Abstract]
Leases	Leases Lessee The Company adopted ASU No. 2016-02, “Leases (Topic 842),” on January 1, 2019, which requires leases with durations greater than twelve months to be recognized on the balance sheet. The Company adopted the standard using the modified retrospective approach utilizing the optional transition method. Prior year financial statements were not recast using this approach. The Company elected the package of practical expedients available for expired or existing contracts, which allowed us to carryforward our historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct costs. Adoption of the new standard resulted in the recording of additional net lease assets and lease liabilities of approximately $68 million and $66 million , respectively, as of January 1, 2019. The standard did not materially impact our consolidated net earnings or cash flows. The Company leases property and equipment under finance and operating leases. The Company's operating leases consist of automobiles in certain countries and real estate, including office, storage and parking spaces. The duration of these leases range from 2 to 10 years. The Company's finance leases primarily consist of equipment financed for the purpose of delivering services to our customers. For leases with terms greater than 12 months, the Company recorded the related asset and obligation at the present value of lease payments over the term. Many of our leases include variable rental escalation clauses which are recognized when incurred. Some of our leases also include renewal options and/or termination options that are factored into the determination of lease payments and lease terms when it is reasonably certain that the Company will exercise these options. Lease agreements do not contain any material residual value guarantees or material restrictive covenants. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. For real estate leases beginning in 2019 and later, we account for lease components ( e.g. , fixed payments including rent, real estate taxes and insurance costs) separately from the non-lease components ( e.g. , common-area maintenance costs). For automobile leases we account for lease and non-lease components together. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, real estate leases do not provide a readily determinable implicit rate. Therefore, the Company must estimate the incremental borrowing rate to discount the lease payments based on information available at lease commencement. The incremental borrowing rate used in the calculation of the lease liability is based on the secured rate associated with financed lease obligations for each location of leased property.

Leases	Leases Lessee The Company adopted ASU No. 2016-02, “Leases (Topic 842),” on January 1, 2019, which requires leases with durations greater than twelve months to be recognized on the balance sheet. The Company adopted the standard using the modified retrospective approach utilizing the optional transition method. Prior year financial statements were not recast using this approach. The Company elected the package of practical expedients available for expired or existing contracts, which allowed us to carryforward our historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct costs. Adoption of the new standard resulted in the recording of additional net lease assets and lease liabilities of approximately $68 million and $66 million , respectively, as of January 1, 2019. The standard did not materially impact our consolidated net earnings or cash flows. The Company leases property and equipment under finance and operating leases. The Company's operating leases consist of automobiles in certain countries and real estate, including office, storage and parking spaces. The duration of these leases range from 2 to 10 years. The Company's finance leases primarily consist of equipment financed for the purpose of delivering services to our customers. For leases with terms greater than 12 months, the Company recorded the related asset and obligation at the present value of lease payments over the term. Many of our leases include variable rental escalation clauses which are recognized when incurred. Some of our leases also include renewal options and/or termination options that are factored into the determination of lease payments and lease terms when it is reasonably certain that the Company will exercise these options. Lease agreements do not contain any material residual value guarantees or material restrictive covenants. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. For real estate leases beginning in 2019 and later, we account for lease components ( e.g. , fixed payments including rent, real estate taxes and insurance costs) separately from the non-lease components ( e.g. , common-area maintenance costs). For automobile leases we account for lease and non-lease components together. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. However, real estate leases do not provide a readily determinable implicit rate. Therefore, the Company must estimate the incremental borrowing rate to discount the lease payments based on information available at lease commencement. The incremental borrowing rate used in the calculation of the lease liability is based on the secured rate associated with financed lease obligations for each location of leased property. The table below presents the lease-related assets and liabilities recorded on the balance sheet: As of in millions, except weighted average calculations Classification on the Balance Sheet June 30, 2019 Assets Operating lease assets Right of use assets - operating lease, net $ 58 Finance lease assets Property and equipment, net 90 Total lease assets $ 148 Liabilities Current Operating Current portion of operating lease liability $ 20 Finance Current portion of finance lease liability 32 Noncurrent Operating Operating lease liability 44 Finance Finance lease liability 54 Total lease liabilities $ 150 Weighted-average remaining lease term Operating leases 3.78 years Finance leases 2.59 years Weighted-average discount rate Operating leases (1) 5.00 % Finance leases 4.70 % (1) Upon adoption of the new lease standard, discount rates used for existing leases were established based on the Company's incremental borrowing rate at January 1, 2019. For new leases entered after January 1, 2019, the discount rate was determined based on the Company's incremental borrowing rate at lease commencement.

For our hardware rental offering, the Company owns or leases the hardware and may or may not provide managed services. Leases sometimes include options to renew but typically do not include lessee purchase options. The revenue for these operating leases is generally recognized straight-line over the term of the contract and is included within the recurring revenue caption. Equipment used for this revenue is reported within Property and equipment, net on the condensed consolidated balance sheet.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share is calculated by dividing net income by the weighted average number of shares outstanding during the reported period. The calculation of diluted earnings per share is similar to basic earnings per share, except that the weighted average number of shares outstanding includes the dilution from potential shares resulting from stock options, restricted stock awards and other stock awards. The components of basic and diluted earnings per share are as follows: Three Months Ended Six Months Ended In millions, except per share amounts 2019 2018 2019 2018 Net (loss) income attributable to common stockholders $ (1 ) $ 4 $ (11 ) $ (3 ) Weighted average outstanding shares of common stock 115.5 119.5 116.3 120.4 Dilutive effect of employee stock options, restricted stock and other stock awards — 2.0 — — Common stock and common stock equivalents 115.5 121.5 116.3 120.4 Net loss (income) per share: Basic $ (0.01 ) $ 0.03 $ (0.09 ) $ (0.02 ) Diluted $ (0.01 ) $ 0.03 $ (0.09 ) $ (0.02 ) For the three months ended June 30, 2019 and six months ended June 30, 2019 and 2018, due to the net loss attributable to Teradata common stockholders, potential common shares that would cause dilution, such as employee stock options, restricted shares and other stock awards, have been excluded from the diluted share count because their effect would have been anti-dilutive. The fully diluted shares would have been 116.7 million for the three months ended June 30, 2019 and 117.7 million and 122.5 million for the six months ended June 30, 2019 and 2018, respectively. Options to purchase 1.6 million and 1.8 million shares of common stock for the three and six months ended June 30, 2019 and 2.5 million and 2.6 million shares of common stock for the three and six months ended June 30, 2018

Segment Reporting [Abstract]
Segment and Other Supplemental Information	Segment and Other Supplemental Information Effective January 1, 2019, Teradata implemented an organizational change in which Teradata now manages its business under three geographic regions, which are also the Company’s operating segments: (1) Americas region (North America and Latin America); (2) EMEA region (Europe, Middle East and Africa) and (3) APAC region (Asia Pacific and Japan). For purposes of discussing results by segment, management excludes the impact of certain items, consistent with the manner by which management evaluates the performance of each segment. This format is useful to investors because it allows analysis and comparability of operating trends. It also includes the same information that is used by Teradata management to make decisions regarding the segments and to assess financial performance. The chief operating decision maker, who is our President and Chief Executive Officer, evaluates the performance of the segments based on revenue and multiple profit measures, including segment gross profit. For management reporting purposes assets are not allocated to the segments. Prior periods have been restated to conform to the current year presentation. The following table presents segment revenue and segment gross profit for the Company: Three Months Ended Six Months Ended In millions 2019 2018 2019 2018 Segment revenue Americas $ 269 $ 287 $ 538 $ 551 EMEA 122 127 235 276 APAC 87 130 173 223 Total revenue 478 544 946 1,050 Segment gross profit Americas 158 154 315 301 EMEA 57 54 107 117 APAC 37 58 71 93 Total segment gross profit 252 266 493 511 Stock-based compensation costs 4 4 7 8 Acquisition, integration, reorganization and transformation-related costs 2 — 5 3 Amortization of capitalized software costs 10 12 21 27 Total gross profit 236 250 460 473 Selling, general and administrative expenses 145 163 296 315 Research and development expenses 81 77 159 152 Income from operations $ 10 $ 10 $ 5 $ 6

Reorganization and Business Transformation	Reorganization and Business Transformation On June 4, 2018, the Company approved a plan to consolidate certain of its operations, including transitioning its corporate headquarters to San Diego, California from its location in Dayton, Ohio. This plan, which is being executed in connection with Teradata’s comprehensive business transformation from a data warehouse company to a data analytics platform company, is intended to better align the Company’s skills and resources to effectively pursue opportunities in the marketplace. The Company recognized costs o f $23 million in 2018 and $12 million in 2019 for employee separation benefits, transition support, facilities lease related costs, outside service, legal and other exit-related costs. The employee separation benefit costs are being expensed over the time period that the employees have to work to earn them. The Company expects that it will incur costs and charges in the range of approximately $35 to $40 million rel ated to the plan and expects the actions will be completed in 2019. Cash paid in 2018 related to the plan listed above was $11 million .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Fair Value Measurement. In August 2018, the Financial Accounting Standards Board ("FASB") issued new guidance that modifies disclosure requirements related to fair value measurement. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this update while delaying adoption of the additional disclosures until their effective date. The Company is currently evaluating this guidance to determine the impact it may have on its disclosures. Compensation-Retirement Benefits-Defined Benefit Plans-General . In August 2018, the FASB issued new guidance that modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. For public companies, the amendments in this update are effective for fiscal years beginning after December 15, 2020, with early adoption permitted, and is to be applied on a retrospective basis to all periods presented. The Company is currently evaluating this guidance to determine the impact it may have on its disclosures. Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. In August 2018, the FASB issued new guidance that reduces complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). For public companies, the amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Implementation should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The effects of this standard on our financial position, results of operations or cash flows are not expected to be material. Codification Improvements to Financial Instruments-Credit Losses, Derivatives and Hedging, and Financial Instruments. In June 2016, the FASB issued Accounting Standards, Measurement of Credit Losses on Financial Instruments, which introduced the expected credit losses methodology for the measurement of credit losses on financial assets measured at amortized cost basis, replacing the previous incurred loss methodology. Since the issuance of this accounting standard, the Board has identified certain areas that require clarification and improvement. In May 2019, the FASB issued guidance that allows entities to make an irrevocable one-time election upon adoption of the new credit losses standard to measure financial assets measured at amortized cost (except held-to-maturity securities) using the fair value option. The election is to be applied on an instrument-by-instrument basis. For entities that have already adopted the new credit losses standard, the relief is effective for fiscal years beginning after December 15, 2019 and interim periods therein, and early adoption is permitted. For all other entities, the guidance is effective upon adoption of the new credit losses standard. The company is currently evaluating this new guidance to determine the impact it may have on our financial position, results of operations or cash flows. Recently Adopted Guidance Leases. In February 2016, the FASB issued new guidance under Topic 842, which requires a lessee to account for leases as finance or operating leases. Both types of leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability on its balance sheet, with differing methodology for income statement and cash flow recognition. For lessors, the standard modifies the classification criteria and the accounting for sales-type and direct financing leases. Entities will classify leases to determine how to recognize lease-related revenue and expense. We adopted the new standard as of January 1, 2019 using the modified retrospective adoption approach utilizing the optional transition method with prior periods not recast and have elected certain of the practical expedients allowed under the standard. The Condensed Consolidated Financial Statements for the three and six months ended June 30, 2019 are presented under the new standard, while comparative years presented are not adjusted and continue to be reported in accordance with our historical accounting policy. See Note 12 for more information. Comprehensive Income. In February 2018, the FASB issued new guidance for Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02), which allows companies to reclassify stranded tax effects resulting from the Tax Reform Act from accumulated other comprehensive income to retained earnings. The impact of applying this standard did not have a material impact on our condensed consolidated financial statements. Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made. In June 2018, the FASB issued new guidance to clarify and improve the scope and the accounting guidance for contributions received and contributions made. The amendments are intended to assist entities in evaluating whether transactions should be accounted for as contributions (nonreciprocal transactions) or as exchange (reciprocal) transactions and determining whether a contribution is conditional. The Company adopted this guidance on January 1, 2019, which did not have a material impact on our condensed consolidated financial statements.
