Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Business DXC Technology Company ("DXC," the "Company," "we," "us," or "our") is a global IT services market leader. We provide mission-critical IT services that transform global businesses. We deliver excellence for our customers and colleagues around the world. Our more than 130,000 people in approximately 70 countries are entrusted by our customers, approximately half of today’s Fortune 500 companies. We operate through two segments: Global Business Services ("GBS") and Global Infrastructure Services ("GIS"), to provide solutions across our six differentiated offerings that modernize operations and drive innovation across our customers' entire IT estate. Basis of Presentation In order to make this report easier to read, DXC refers throughout to (i) the Consolidated Financial Statements as the “financial statements,” (ii) the Consolidated Statements of Operations as the “statements of operations,” (iii) the Consolidated Statement of Comprehensive (Loss) Income as the "statements of comprehensive income," (iv) the Consolidated Balance Sheets as the “balance sheets,” and (v) the Consolidated Statements of Cash Flows as the “statements of cash flows.” In addition, references are made throughout to the numbered Notes to the Consolidated Financial Statements (“Notes”) in this Annual Report on Form 10-K. The accompanying financial statements have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission for annual reports and accounting principles generally accepted in the United States ("GAAP"). The financial statements include the accounts of DXC, its consolidated subsidiaries, and those business entities in which DXC maintains a controlling interest. Investments in business entities in which the Company does not have control, but has the ability to exercise significant influence over operating and financial policies, are accounted for by the equity method. Other investments are accounted for by the cost method. Non-controlling interests are presented as a separate component within equity in the balance sheets. Net earnings attributable to the non-controlling interests are presented separately in the statements of operations, and comprehensive (loss) income attributable to non-controlling interests are presented separately in the statements of comprehensive (loss) income. All intercompany transactions and balances have been eliminated. Certain amounts reported in the previous year have been reclassified to conform to the current year presentation. Use of Estimates The preparation of the financial statements, in accordance with GAAP, requires the Company's management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosure of contingent assets and liabilities. The Company bases its estimates on assumptions regarding historical experience, currently available information, and anticipated developments that it believes are reasonable and appropriate. However, because the use of estimates involves an inherent degree of uncertainty, actual results could differ from those estimates. Estimates are used for, but not limited to, contracts accounted for using the percentage-of-completion method, cash flows used in the evaluation of impairment of goodwill and other long-lived assets, reserves for uncertain tax positions, valuation allowances on deferred tax assets, loss accruals for litigation, and obligations related to our pension plans. In the opinion of the Company's management, the accompanying financial statements contain all adjustments necessary, including those of a normal recurring nature, to fairly present the financial statements. Leases The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether DXC obtains substantially all economic benefits from and has the ability to direct the use of the asset. Leased assets classified as operating leases are included in operating right-of-use ("ROU") assets, net, with the associated liabilities included in current operating lease liabilities and non-current operating lease liabilities in DXC's balance sheets. Finance leases are included in property and equipment, net, short-term debt and current maturities of long-term debt and long-term debt, net of current maturities in DXC's balance sheets. Leased assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Lease liabilities are recognized at commencement based on the present value of fixed or in-substance fixed lease payments over the lease term. Leased assets are recognized at commencement based upon the leased liability plus any lease payments made at or before lease commencement and excluding any lease incentives. As most of the Company's leases do not provide an implicit rate, DXC uses its incremental borrowing rate based on the information available at commencement to determine the present value of lease payments. The incremental borrowing rate is the rate of interest that DXC would have to pay to borrow, on a collateralized basis, an amount equal to the lease payments, in a similar economic environment and over a similar term. The rate is dependent on several factors, including the lease term, currency of the lease payments and the Company's credit ratings. The Company's lease terms may include options to extend or terminate the lease. Leased assets and lease liabilities include these options when it is reasonably certain that they will be exercised. Lease arrangements generally do not contain any residual value guarantees or material restrictive covenants. Operating lease expense, which includes interest, is recognized on a straight-line basis over the lease term with variable payments, primarily related to the operational costs for the Company's leased real estate for offices, which are recognized as incurred. Assets obtained under finance leases are recorded as fixed assets and depreciated over the shorter of the depreciable life of the asset or the lease term. Revenue Recognition The Company's primary service offerings are information technology outsourcing, other professional services, or a combination thereof. Revenues are recognized when control of the promised goods or services is transferred to DXC's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. DXC determines revenue recognition through the five-step model as follows: • Identification of the contract, or contracts, with a customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, the Company satisfies a performance obligation DXC's IT outsourcing ("ITO") arrangements typically reflect a single performance obligation that comprises a series of distinct services which are substantially the same and provided over a period of time using the same measure of progress. Revenue derived from these arrangements is recognized over time based upon the level of services delivered in the distinct periods in which they are provided based on time increments. When other parties are involved in providing goods or services as part of our customer arrangements, DXC recognizes revenue on a gross basis as a principal when it controls goods or services before they are transferred to the customer. In addition, the Company reports revenue net of any revenue-based taxes assessed by a governmental authority that are imposed on and concurrent with specific revenue-producing transactions, such as sales taxes and value-added taxes. DXC's contracts often include upfront fees billed for activities to familiarize DXC with the customers' operations, take control over their administration and operation, and adapt them to DXC's solutions. Upfront fees are generally recognized ratably over the contract period, which approximates the manner in which the services are provided. These activities typically do not qualify as performance obligations, and the related revenues are allocated to the relevant performance obligations and recognized ratably over time as the performance obligation is satisfied during the period in which DXC provides the related service, which is typically the life of the contract. Software transactions that include multiple performance obligations are described below. For contracts with multiple performance obligations, DXC allocates the contract’s transaction price to each performance obligation based on the relative standalone selling price of each distinct good or service in the contract. Other than software sales involving multiple performance obligations, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which the Company forecasts its expected costs of satisfying a performance obligation and then adds an appropriate margin for that distinct good or service. DXC's ITO arrangements may also contain embedded leases for equipment used to fulfill services. A contract with a customer includes an embedded lease when DXC grants the customer a right to control the use of an identified asset for a period of time in exchange for consideration. Embedded leases with customers are typically recognized either as sales type leases in which revenue and co st of sales is recognized upon lease commencement; or they may be recognized as operating leases in which revenue is recognized over the usage period. Where a contract contains an embedded lease, the contract’s transaction price is allocated to the contract performance obligations and the lease component based upon the relative standalone selling price. The transaction price of a contract is determined based on fixed and variable consideration. Variable consideration related to the Company’s ITO offerings often includes volume-based pricing that is allocated to the distinct days of the services to which the variable consideration pertains. However, in certain cases, estimates of variable consideration, including penalties, contingent milestone payments and rebates are necessary. The Company only includes estimates of variable consideration in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. These judgments involve consideration of historical and expected experience with the customer and other similar customers, and the facts and circumstances specific to the arrangement. Contracts with our customers may be modified over the course of the contract term and we may change the scope, price or both of the existing contracts. Contract modifications are reviewed to determine whether they should be accounted for as part of the original contract, the termination of an existing contract and the creation of a new contract, or as a separate contract. Contract modifications are a separate contract when the modification provides additional goods and services that are distinct and the transaction price is at the standalone selling price. If the contract modification is part of the existing contract, a cumulative adjustment to revenue is recorded. If the contract modification represents the termination of the existing contract and the creation of a new contract, the modified transaction price is allocated to the prospective performance obligations and any embedded lease components. If a contract modification modifies an embedded lease component and the modification is not accounted for as a separate contract, the classification of the lease is reassessed. The Company generally provides its services under time and materials contracts, unit-price contracts, fixed-price contracts, and software contracts for which revenue is recognized in the following manner: Time and materials contracts . Revenue is recognized over time at agreed-upon billing rates when services are provided. Unit-price contracts. Revenue is recognized over time based on unit metrics multiplied by the agreed-upon contract unit price or when services are delivered. Fixed-price contracts. For certain fixed-price contracts, revenue is recognized over time using a method that measures the extent of progress towards completion of a performance obligation, generally using a cost-input method (referred to as the percentage-of-completion cost-to-cost method). Under the percentage-of-completion cost-to-cost method, revenue is recognized based on the proportion of total cost incurred to estimated total costs at completion. A performance obligation's estimate at completion includes all direct costs such as materials and labor. If output or input measures are not available or cannot be reasonably estimated, revenue is deferred until progress can be measured and costs are not deferred unless they meet the criteria for capitalization. Under the percentage-of-completion cost-to-cost method, progress towards completion is measured based on costs incurred as a proportion of estimated total costs. Profit in a given period is reported at the estimated profit margin to be achieved on the overall contract. If estimated total costs at completion exceed estimated revenue for a contract under the percentage-of-completion cost-to-cost method, the loss is recognized in the quarter it first becomes probable and reasonably estimable. Software contracts. Certain of DXC's arrangements involve the sale of DXC proprietary software, post-contract customer support, and other software-related services. The standalone selling price generally is determined for each performance obligation using an adjusted market assessment approach based on the price charged where each deliverable is sold separately. In certain limited cases (typically for software licenses) when the historical selling price is highly variable, the residual approach is used. This approach allocates revenue to the performance obligation equal to the difference between the total transaction price and the observable standalone selling prices for the other performance obligations. Revenue from distinct software licenses is recognized at a point in time when the customer can first use the software license. If significant customization is required, software revenue is recognized as the related software customization services are performed in accordance with the percentage-of-completion method described above. Revenue for post-contract customer support and other software services is recognized over time as those services are provided . Practical Expedients DXC does not adjust the promised amount of consideration for the effects of a significant financing component when the period between when DXC transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. Contract Balances The timing of revenue recognition, billings and cash collections results in accounts receivable (billed receivables, unbilled receivables and contract assets) and deferred revenue and advance contract payments (contract liabilities) on the Company's balance sheets. In arrangements that contain an element of customized software solutions, amounts are generally billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g. monthly) or upon achievement of certain contractual milestones. Generally, billing occurs subsequent to revenue recognition, sometimes resulting in contract assets if the related billing is conditional upon more than just the passage of time. However, the Company sometimes receives advances or deposits from customers, before revenue is recognized, which results in the generation of contract liabilities. Payment terms vary by type of product or service being provided as well as by customer, although the term between invoicing and when payment is due is generally an insignificant period of time. Costs to Obtain a Contract Certain sales commissions earned by the Company's sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The majority of sales commissions are paid based on the achievement of quota-based targets. These costs are deferred and amortized on a straight-line basis over an average period of benefit determined to be five years. The Company determined the period of benefit considering the length of its customer contracts, its technology, and other factors. Some commission payments are not capitalized because they are expensed during the fiscal year as the related revenue is recognized. Capitalized sales commissions costs are classified within other assets and amortized in selling, general and administrative expenses. Costs to Fulfill a Contract Certain contract setup costs incurred upon initiation or renewal of an outsourcing contract that generate or enhance resources to be used in satisfying future performance obligations are capitalized when they are deemed recoverable. Judgment is applied to assess whether contract setup costs are capitalizable. Costs that generate or enhance resources often pertain to activities that enhance the capabilities of the services, improve customer experience, and establish a more effective and efficient IT environment. The Company recognizes these transition and transformation contract costs as other assets, which are amortized over the respective contract life. Pension and Other Benefit Plans The Company accounts for its pension, other post-retirement benefit ("OPEB"), defined contribution and deferred compensation plans using the guidance of ASC 710 "Compensation – General" and ASC 715 "Compensation – Retirement Benefits." The Company recognizes actuarial gains and losses and changes in fair value of plan assets in earnings at the time of plan remeasurement as a component of net periodic benefit expense. Typically plan remeasurement occurs annually during the fourth quarter of each fiscal year. The remaining components of pension and OPEB expense, primarily current period service and interest costs and expected return on plan assets, are recorded on a quarterly basis. Inherent in the application of the actuarial methods are key assumptions, including, but not limited to, discount rates, expected long-term rates of return on plan assets, mortality rates, rates of compensation increases, and medical cost trend rates. Company management evaluates these assumptions annually and updates assumptions as necessary. The fair value of assets is determined based on the prevailing market prices or estimated fair value of investments when quoted prices are not available. Software Development Costs After establishing technological feasibility, and until such time as the software products are available for general release to customers, the Company capitalizes costs incurred to develop commercial software products to be sold, leased or otherwise marketed. Costs incurred to establish technological feasibility are charged to expense as incurred. Enhancements to software products are capitalized where such enhancements extend the life or significantly expand the marketability of the products. Amortization of capitalized software development costs is determined separately for each software product. Annual amortization expense is calculated based on the greater of the ratio of current gross revenues for each product to the total of current and anticipated future gross revenues for the product or the straight-line amortization method over the estimated useful life of the product. Unamortized capitalized software costs associated with commercial software products are periodically evaluated for impairment on a product-by-product basis by comparing the unamortized balance to the product’s net realizable value. The net realizable value is the estimated future gross revenues from that product reduced by the related estimated future costs. When the unamortized balance exceeds the net realizable value, the unamortized balance is written down to the net realizable value and an impairment charge is recorded. The Company capitalizes costs incurred to develop internal-use computer software during the application development stage. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Internal and external costs incurred in connection with development of upgrades or enhancements that result in additional functionality are also capitalized. Capitalized costs associated with internal-use software are amortized on a straight-line basis over the estimated useful life of the software. Purchased software is capitalized and amortized over the estimated useful life of the software. Internal-use software assets are evaluated for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Share-Based Compensation Share-based awards are accounted for under the fair value method. The Company provides different forms of share-based compensation to its employees and non-employee directors. This generally includes restricted stock units ("RSUs"), including performance-based restricted stock units ("PSUs"). The fair value of the awards is determined on the grant date, based on the Company's closing stock price. For awards settled in shares, the Company recognizes compensation expense based on the grant-date fair value net of estimated forfeitures over the vesting period. For awards settled in ca sh, the Company recognizes compensation expense based on the fair value at each reporting date net of estimated forfeitures. Goodwill Impairment Analysis The Company tests goodwill for impairment on an annual basis as of the first day of the second fiscal quarter and between annual tests if circumstances change, or if an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company has defined its reporting units as its reportable segments. A significant amount of judgment is involved in determining whether an event indicating impairment has occurred between annual testing dates. Such indicators include: a significant decline in the Company's stock price, a significant decline in expected future cash flows, a significant adverse change in legal factors or in the business climate, unanticipated competition, the disposal of a significant component of a reporting unit and the testing for recoverability of a significant asset group within a reporting unit. The Company initially assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. This qualitative assessment considers all relevant factors specific to the reporting units, including macroeconomic conditions, industry and market considerations, overall financial performance, and relevant entity-specific events. If the Company determines that it is not more likely than not that the carrying amount for a reporting unit is less than its fair value, then subsequent quantitative goodwill impairment testing is not required. If the Company determines that it is more likely than not that the carrying amount for a reporting unit is greater than its fair value, then it proceeds with a subsequent quantitative goodwill impairment test. The Company has the option to bypass the initial qualitative assessment stage and proceed directly to the quantitative goodwill impairment test. The quantitative goodwill impairment test compares each reporting unit’s fair value to its carrying value. If the reporting unit’s fair value exceeds its carrying value, no further procedures are required. However, if a reporting unit’s fair value is less than its carrying value, then an impairment charge is recorded in the amount of the excess . When the Company performs the quantitative goodwill impairment test for a reporting unit, it estimates the fair value of the reporting unit using a combination of an income approach and a market approach. The income approach utilizes a discounted cash flow analysis in which the estimated future cash flows and terminal values for each reporting unit are discounted to present value using a discount rate. Cash flow projections are based on management's estimates of economic and market conditions, which drive key assumptions of revenue growth rates, operating margins, capital expenditures and working capital requirements. The discount rate is based on the weighted-average cost of capital and may be adjusted for the relevant risks associated with business-specific characteristics and any uncertainty related to a reporting unit’s ability to execute on the projected future cash flows. The market approach estimates fair value by applying performance-metric multiples to the reporting unit's prior and expected operating performance. The multiples are derived from comparable publicly traded companies that have operating and investment characteristics similar to those of the reporting unit. If the fair value of the reporting unit derived using one approach is significantly different from the fair value estimate using the other approach, the Company reevaluates its assumptions used in the two models. Assumptions are modified as considered appropriate under the circumstances until the two models yield similar and reasonable results. The fair values determined by the market approach and income approach, as described above, are weighted to determine the fair value for each reporting unit. Fair Value The Company applies fair value accounting for its financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The objective of a fair value measurement is to estimate the price to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. Assets and liabilities subject to fair value measurement disclosures are required to be classified according to a three-level fair value hierarchy with respect to the inputs used to determine fair value. The level in which an asset or liability is disclosed within the fair value hierarchy is based on the lowest level input that is significant to the related fair value measurement in its entirety. The levels of input are defined as follows: Level 1: Quoted prices unadjusted for identical assets or liabilities in an active market. Level 2: Quoted prices for similar assets or liabilities in an active market, quoted prices for identical similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data. Level 3: Unobservable inputs that reflect the entity's own assumptions which market participants would use in pricing the asset or liability. Receivables The Company records receivables at their face amounts less an allowance for doubtful accounts. Receivables consist of amounts billed and currently due from customers, amounts earned but unbilled (including contracts measured under the percentage-of-completion cost-to-cost method of accounting), amounts retained by the customer until the completion of a specified contract and claims. Unbilled recoverable amounts under contracts in progress generally become billable upon the passage of time, the achievement of project milestones, or upon acceptance by the customer. Allowances for uncollectible trade receivables are estimated based on a combination of write-off history, aging analysis, any known collectability issues, and certain forward-looking information. DXC uses receivables securitization facilities or receivables sales facilities in the normal course of business as part of managing its cash flows. The Company accounts for receivables sold under these facilities as a sale of financial assets pursuant to ASC 860 “Transfers and Servicing” and derecognizes these receivables, as well as the related allowances, from its balance sheets. Generally, the fair value of the sold receivables approximates the book value due to the short-term nature and, as a result, no gain or loss on sale of receivables is recorded. Property and Equipment Property and equipment, which include assets under capital leases, are stated at cost less accumulated depreciation. Depreciation is computed predominantly on a straight-line basis over the estimated useful lives of the assets or the remaining lease term. The estimated useful lives of DXC's property and equipment are as follows: Buildings Up to 40 years Computers and related equipment 4 to 7 years Furniture and other equipment 3 to 15 years Leasehold improvements Shorter of lease term or useful life up to 20 years Intangible Assets The Company's estimated useful lives for finite-lived intangibles are shown in the table below: Software 2 to 10 years Customer related intangibles Expected customer service life Acquired contract related intangibles Contract life and first contract renewal, where applicable Software is amortized using predominately the straight-line method (see Software Development Costs above). Acquired contract related and customer related intangible assets are amortized in proportion to the estimated undiscounted cash flows projected over the estimated life of the asset or on a straight-line basis if such cash flows cannot be reliably estimated. Impairment of Long-Lived Assets and Finite-Lived Intangible Assets Long-lived assets such as property and equipment and finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable. Recoverability of long-lived assets or groups of assets is assessed based on a comparison of the carrying amount of such assets to the estimated future net cash flows. If estimated future net cash flows are less than the carrying amount of such assets, an expense is recorded in the amount required to reduce the carrying amount of such assets to fair value. Fair value is determined based on a discounted cash flow approach or, when available and appropriate, comparable market values. Long-lived assets to be disposed of are reported at the lower of their carrying amount or their fair value less costs to sell. Assets/Liabilities Held for Sale The Company classifies assets as held for sale in the period when the following conditions are met: (i) management, having the authority to approve the action, commits to a plan to sell the asset (disposal group); (ii) the asset (disposal group) is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets (disposal group); (iii) an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; (iv) the sale of the asset (disposal group) is probable, and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond our control extend the period of time required to sell the asset (disposal group) beyond one year; (v) the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A long-lived asset (disposal group) that is classified as held for sale is initially measured at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset (disposal group) until the date of sale. Income Taxes The Company uses the liability method in accounting for income taxes. Deferred tax assets and liabilities are recorded for the expected future tax consequences of temporary differences between financial statement carrying amounts of assets and liabilities and their respective tax bases, using statutory tax rates in effect for the year in which the differences are expected to reverse.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures	Divestitures Fiscal 2023 Divestitures On January 3, 2023, DXC completed the sale of its German financial services subsidiary ("FDB" or the "FDB Business") to the FNZ Group ("FNZ") for €308 million (approximately $329 million), resulting in a pre-tax gain of approximately $215 million. Included in the FDB sale was AXA Bank Germany, a German retail bank, that DXC acquired for total consideration of $101 million on January 1, 2021. The following is a summary of the assets and liabilities distributed as part of the FDB Sale on January 3, 2023: (in millions) As of January 3, 2023 Assets: Cash and cash equivalents $ 509 Accounts receivable, net 67 Prepaid expenses 1 Total current assets 577 Intangible assets, net 45 Goodwill 48 Property and equipment, net 1 Other assets 12 Total non-current assets 106 Total assets $ 683 Liabilities: Accounts payable $ 5 Accrued expenses and other current liabilities 529 Income taxes payable 1 Total current liabilities 535 Non-current income tax liabilities and deferred tax liabilities 6 Other long-term liabilities 4 Total long-term liabilities 10 Total liabilities $ 545 During fiscal 2023, the Company sold insignificant businesses that resulted in a net loss of $25 million. Included in this amount was the Company's primary Russian entity that the Company sold in the second quarter of fiscal 2023, in response to the ongoing sanctions against certain industry sectors and parties in Russia due to Russia's invasion of Ukraine. As of March 31, 2023, the Company had entered into definitive agreements to sell insignificant businesses and assets, which are classified as held for sale. Fiscal 2022 Divestitures HPS Sale During fiscal 2022, DXC completed the sale of its healthcare provider software business (“HPS” or the “HPS Business”) to Dedalus Holding S.p.A. (“Dedalus”) for €468 million (approximately $551 million), resulting in a pre-tax gain on sale of $331 million, net of closing costs. During fiscal 2022, the Company sold some insignificant businesses that resulted in a gain of $53 million. This was partially offset by $13 million in sales price adjustments related to prior year dispositions, which resulted from changes in estimated net working capital. Fiscal 2021 Divestitures HHS Sale During fiscal 2021, DXC completed the sale of its U.S. State and Local Health and Human Services business ("HHS" or the "HHS Business") to Veritas Capital Fund Management, L.L.C. ("Veritas Capital"), for approximately $5.0 billion, resulting in a pre-tax gain on sale of $2,014 million. Approximately $3.5 billion of the sale proceeds was used to prepay debt. During fiscal 2021, the Company sold some insignificant businesses that resulted in a loss of $10 million.

The following table presents the change in balance for the allowance for doubtful accounts: As of and for Fiscal Years Ended (in millions) March 31, 2023 March 31, 2022 Beginning balance $ 55 $ 91 Provisions for losses on accounts receivable (1) 5 Other adjustments to allowance and write-offs (7) (41) Ending balance $ 47 $ 55 Receivables Facility The Company has an accounts receivable sales facility (as amended, restated, supplemented or otherwise modified as of March 31, 2023, the "Receivables Facility") with certain unaffiliated financial institutions (the "Purchasers") for the sale of commercial accounts receivable in the United States. The Receivables Facility has a facility limit of $400 million as of March 31, 2023. The Receivables Facility was amended on July 29, 2022, extending the termination date to July 28, 2023. Under the Receivables Facility, certain of the Company subsidiaries (the "Sellers") sell accounts receivable to DXC Receivables LLC ("Receivables SPV"), a wholly owned bankruptcy-remote entity, in a true sale. Receivables SPV subsequently sells certain of the receivables in their entirety to the Purchasers pursuant to a receivables purchase agreement. The financial obligations of Receivables SPV to the Purchasers under the Receivables Facility are limited to the assets it owns and non-recourse to the Company. Sales of receivables by Receivables SPV occur continuously and are settled monthly. The amount available under the Receivables Facility fluctuates over time based on the total amount of eligible receivables generated during the normal course of business after deducting excess concentrations. As of March 31, 2023, the total availability under the Receivables Facility was $400 million and the amount sold to the Purchasers was $400 million, which was derecognized from the Company's balance sheet. The fair value of the sold receivables approximated their book value due to their short-term nature, resulting in no gain or loss recorded on the sale of receivables. While the Company guarantees certain non-financial performance obligations of the Sellers, the Purchasers bear customer credit risk associated with the receivables sold under the Receivables Facility and have recourse in the event of credit-related customer non-payment solely to the assets of the Receivables SPV. Milano Receivables Facility On October 1, 2020, in connection with the sale of the HHS Business, the Milano Facility was terminated. For more information, refer to Note 2 - "Divestitures." German Receivables Facility On June 30, 2021, the Company terminated its accounts receivable securitization facility with certain unaffiliated financial institutions for the sale of commercial accounts receivable in Germany (the "DE Receivables Facility"). Under the DE Receivables Facility, the deferred purchase price ("DPP") was classified as cash flows from investing activities. See Note 18 – “Cash Flows” for additional information.

Fair Value	Fair Value Fair Value Measurements on a Recurring Basis The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis, excluding pension assets and derivative assets and liabilities. See Note 14 - "Pension and Other Benefit Plans" and Note 7 - "Derivative Instruments" for information about these excluded assets and liabilities. There were no transfers between any of the levels during the periods presented. Fair Value Hierarchy (in millions) As of March 31, 2023 Assets: Fair Value Level 1 Level 2 Level 3 Money market funds and money market deposit accounts $ 75 $ 75 $ — $ — Time deposits (1) 37 37 — — Other securities (2) 48 — 46 2 Total assets $ 160 $ 112 $ 46 $ 2 Liabilities: Contingent consideration $ 2 $ — $ — $ 2 Total liabilities $ 2 $ — $ — $ 2 (in millions) As of March 31, 2022 Assets: Fair Value Level 1 Level 2 Level 3 Money market funds and money market deposit accounts $ 5 $ 5 $ — $ — Time deposits (1) 51 51 — — Other securities (2) 51 — 49 2 Total assets $ 107 $ 56 $ 49 $ 2 Liabilities: Contingent consideration $ 8 $ — $ — $ 8 Total Liabilities $ 8 $ — $ — $ 8 (1) Cost basis approximated fair value due to the short period of time to maturity. (2) Other securities include available-for-sale equity security investments with Level 2 inputs that have a cost basis of $52 million and $53 million as of March 31, 2023 and March 31, 2022, respectively. For the periods presented, gains and losses are insignificant and are included in other expense (income), net in the Company’s statements of operations. The fair value of money market funds, money market deposit accounts, U.S. Treasury bills with less than three months maturity and time deposits, included in cash and cash equivalents, are based on quoted market prices. The fair value of other equity securities, included in other long-term assets, is based on actual market prices. The fair value of contingent consideration, included in other liabilities, is based on contractually defined targets of financial performance in connection with earn outs and other considerations. Other Fair Value Disclosures The carrying amounts of the Company’s financial instruments with short-term maturities, primarily accounts receivable, accounts payable, short-term debt, and financial liabilities included in other accrued liabilities approximate their market values due to their short-term nature. If measured at fair value, these financial instruments would be classified as Level 2 or Level 3 within the fair value hierarchy. Note 11 - “Debt” includes information about the estimated fair value of the Company's long-term debt. Non-financial assets such as goodwill, tangible assets, intangible assets, and other contract related long-lived assets are recorded at fair value in the period they are initially recognized; and such fair value may be adjusted in subsequent periods if an event occurs or circumstances change that indicate that the asset may be impaired. The fair value measurements in such instances would be classified as Level 3 within the fair value hierarchy. There were no significant impairments recorded during the fiscal periods covered by this report.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In the normal course of business, the Company is exposed to interest rate and foreign exchange rate fluctuations. As part of its risk management strategy, the Company uses derivative instruments, primarily foreign currency forward contracts and interest rate swaps, to hedge certain foreign currency and interest rate exposures. The Company’s objective is to reduce earnings volatility by offsetting gains and losses resulting from these exposures with losses and gains on the derivative contracts used to hedge them. The Company does not use derivative instruments for trading or any speculative purpose. Derivatives Designated for Hedge Accounting Cash flow hedges The Company has designated certain foreign currency forward contracts as cash flow hedges to reduce foreign currency risk related to certain Indian Rupee, Euro and British Pound-denominated intercompany obligations and forecasted transactions. The notional amounts of foreign currency forward contracts designated as cash flow hedges as of March 31, 2023 and March 31, 2022 were $842 million and $727 million, respectively. As of March 31, 2023, the related forecasted transactions extend through June 2025. For the fiscal years ended March 31, 2023 and March 31, 2022, the Company performed an assessment at the inception of the cash flow hedge transactions and determined that all critical terms of the hedging instruments and hedged items matched. The Company performs an assessment of critical terms on an on-going basis throughout the hedging period. During the fiscal years ended March 31, 2023 and March 31, 2022, the Company had no cash flow hedges for which it was probable that the hedged transaction would not occur. As of March 31, 2023, $6 million of the existing amount of loss related to the cash flow hedge reported in accumulated other comprehensive loss is expected to be reclassified into earnings within the next 12 months. Amounts recognized in other comprehensive (loss) income and (loss) income before income taxes The pre-tax (loss) gain on derivatives designated for hedge accounting recognized in other comprehensive (loss) income was $(11) million and $23 million during the fiscal year ended March 31, 2023 and March 31, 2022, respectively. The pre-tax gain on derivatives designated for hedge accounting recognized in (loss) income before income taxes was $11 million and $6 million during the fiscal year ended March 31, 2023 and March 31, 2022, respectively. Derivatives Not Designated For Hedge Accounting The derivative instruments not designated as hedges for purposes of hedge accounting include certain short-term foreign currency forward contracts. Derivatives that are not designated as hedging instruments are adjusted to fair value through earnings in the financial statement line item to which the derivative relates. Foreign currency forward contracts The Company manages the exposure to fluctuations in foreign currencies by using foreign currency forward contracts to hedge certain foreign currency denominated assets and liabilities, including intercompany accounts and forecasted transactions. The notional amount of the foreign currency forward contracts outstanding as of March 31, 2023 and March 31, 2022 was $2.5 billion and $2.1 billion, respectively. The following table presents the pre-tax amounts impacting income related to foreign currency forward contracts designated and non-designated for hedge accounting: Fiscal Years Ended (in millions) Statement of Operations Line Item March 31, 2023 March 31, 2022 March 31, 2021 Foreign currency forward contracts Other (income) expense, net $ (27) $ 52 $ 51 Fair Value of Derivative Instruments All derivative instruments are recorded at fair value. The Company’s accounting treatment for these derivative instruments is based on its hedge designation. The following tables present the fair values of derivative instruments included in the balance sheets: As of (in millions) Balance Sheet Line Item March 31, 2023 March 31, 2022 Derivatives designated for hedge accounting: Foreign currency forward contracts Other current assets $ 6 $ 18 Accrued expenses and other current liabilities $ 13 $ — Derivatives not designated for hedge accounting: Foreign currency forward contracts Other current assets $ 15 $ 9 Accrued expenses and other current liabilities $ 16 $ 15 The fair value of foreign currency forward contracts represents the estimated amount required to settle the contracts using current market exchange rates and is based on the period-end foreign currency exchange rates and forward points that are classified as Level 2 inputs. Other Risks for Derivative Instruments The Company is exposed to the risk of losses in the event of non-performance by the counterparties to its derivative contracts. The amount subject to credit risk related to derivative instruments is generally limited to the amount, if any, by which a counterparty's obligations exceed the obligations of the Company with that counterparty. To mitigate counterparty credit risk, the Company regularly reviews its credit exposure and the creditworthiness of the counterparties. With respect to its foreign currency derivatives, as of March 31, 2023, there were five counterparties with concentration of credit risk, and based on gross fair value, the maximum amount of loss that the Company could incur is $3 million. The Company also enters into enforceable master netting arrangements with some of its counterparties. However, for financial reporting purposes, it is the Company's policy not to offset derivative assets and liabilities despite the existence of enforceable master netting arrangements. The potential effect of such netting arrangements on the Company's balance sheets is not material for the periods presented. Non-Derivative Financial Instruments Designated for Hedge Accounting The Company applies hedge accounting for foreign currency-denominated debt used to manage foreign currency exposures on its net investments in certain non-U.S. operations. To qualify for hedge accounting, the hedging instrument must be highly effective at reducing the risk from the exposure being hedged. Net Investment Hedges DXC seeks to reduce the impact of fluctuations in foreign exchange rates on its net investments in certain non-U.S. operations with foreign currency-denominated debt. For foreign currency denominated debt designated as a hedge, the effectiveness of the hedge is assessed based on changes in spot rates. For qualifying net investment hedges, all gains or losses on the hedging instruments are included in currency translation. Gains or losses on individual net investments in non-U.S. operations are reclassified to earnings from accumulated other comprehensive (loss) income when such net investments are sold or substantially liquidated. As of March 31, 2023, DXC had $0.3 billion of foreign currency-denominated debt designated as hedges of net investments in non-U.S. subsidiaries. For the fiscal year ended March 31, 2023, the pre-tax impact of gain on foreign currency-denominated debt designated for hedge accounting recognized in other comprehensive loss was $6 million. As of March 31, 2022, DXC had $0.3 billion of foreign currency-denominated debt designated as hedges of net investments in non-U.S. subsidiaries.

Goodwill Impairment Analyses The Company’s annual goodwill impairment analyses, which were performed qualitatively in the second quarter of fiscal years 2023, 2022, and 2021, did not result in an impairment charge. At the end of each fiscal year, the Company assessed whether there were events or changes in circumstances that would more likely than not reduce the fair value of any of its reporting units below its carrying amount and require goodwill to be tested for impairment. The Company determined that there have been no such indicators, and, therefore, it was unnecessary to perform an interim goodwill impairment test as of the end of each respective fiscal year.

Retirement Benefits [Abstract]
Pension and Other Benefit Plans	Pension and Other Benefit Plans The Company offers a number of pension and OPEB plans, life insurance benefits, deferred compensation and defined contribution plans. Most of the Company's pension plans are not admitting new participants; therefore, changes to pension liabilities are primarily due to market fluctuations of investments for existing participants and changes in interest rates. Defined Benefit Plans The Company sponsors a number of defined benefit and post-retirement medical benefit plans for the benefit of eligible employees. The benefit obligations of the Company's U.S. pension, U.S. OPEB, and non-U.S. OPEB plans represent an insignificant portion of the Company's pension and other post-retirement benefit plans. As a result, the disclosures below include the Company's U.S. and non-U.S. pension plans on a global consolidated basis. Eligible employees are enrolled in defined benefit pension plans in their country of domicile. The defined benefit pension plan in the U.K. represents the largest plan. In addition, healthcare, dental and life insurance benefits are also provided to certain non-U.S. employees. A significant number of employees outside the United States are covered by government sponsored programs at no direct cost to the Company other than related payroll taxes. During fiscal 2023, pension trustees and the Company took actions to reduce the volatility of a defined benefit pension plan in the U.K., including entering into pension risk transfer transactions involving the purchase of annuity contracts for portions of its outstanding defined benefit pension obligations using assets from the pension trust. In connection with this transaction, the pension trustees transferred $1.0 billion of gross defined benefit pension obligations and related plan assets to an insurance company for approximately 5,000 U.K. plan participants. In addition, the Company recognized a noncash pension settlement charge of $361 million, which includes the accelerated recognition of prior service credit that was included in accumulated other comprehensive income. This transaction is irrevocable, and as a result of the transaction, the pension trustees and the Company were relieved of all responsibility for the related pension obligations and the insurance company is now required to pay and administer the retirement benefits. The Company accrued $0 million, $4 million and $13 million, for fiscal 2023, 2022 and 2021, respectively, as additional contractual termination benefits for certain employees as part of the Company's restructuring plans. These amounts are reflected in the projected benefit obligation and in the net periodic pension cost. The change in projected benefit obligation for fiscal year 2023 is primarily related to actuarial gains, the pension risk transfer transaction discussed above, and foreign currency exchange rate changes. Actuarial gains were primarily due to an increase in discount rates across most plans and lower inflation rate assumptions primarily in the United Kingdom, with partially offsetting impact of actuarial losses primarily from higher than expected benefit indexation in the United Kingdom.

Equity assets in commingled funds reporting a net asset value are categorized as Level 2 and valued using broker dealer bids or quotes of securities with similar characteristics. Fixed income accounts are categorized as Level 1 if traded on a publicly quoted exchange or as level 2 if investments in corporate bonds are primarily investment grade bonds, generally priced using model-based pricing methods that use observable market data as inputs. Broker dealer bids or quotes of securities with similar characteristics may also be used. Alternative investment fund securities are categorized as Level 1 if held in a mutual fund or in a separate account structure and actively traded through a recognized exchange, or as Level 2 if they are held in commingled or collective account structures and are actively traded. Alternative investment fund securities are classified as Level 3 if they are held in Limited Company or Limited Partnership structures or cannot otherwise be classified as Level 1 or Level 2. Other assets represent property holdings by certain pension plans. As above, the property holdings represent a master lease arrangement entered into by DXC in the U.K. and certain U.K. pension plans as a financing transaction. Insurance contracts purchased to cover benefits payable to retirees are valued using the assumptions used to value the projected benefit obligation. Cash equivalents that have quoted prices in active markets are classified as Level 1. Short-term money market commingled funds are categorized as Level 2 and valued at cost plus accrued interest which approximates fair value. Plan Asset Allocations As of Asset Category March 31, 2023 March 31, 2022 Equity securities 10 % 18 % Debt securities 49 % 37 % Alternatives 35 % 39 % Cash and other 6 % 6 % Total 100 % 100 % Plan assets are held in a trust that includes commingled funds subject to country specific regulations and invested primarily in commingled funds. For the U.K. pension plans, the Company's largest pension plans by assets and projected liabilities, a target allocation by asset class was developed to achieve their long-term objectives. Asset allocations are monitored closely and investment reviews regarding asset strategy are conducted regularly with internal and external advisors. The Company’s investment goals and risk management strategy for plan assets evaluates a number of factors, including the time horizon of the plans’ obligations. Plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification in order to reduce risk, yet produces a reasonable amount of return on investment over the long term. Sufficient liquidity is maintained to meet benefit obligations as they become due. Third party investment managers are employed to invest assets in both passively-indexed and actively-managed strategies. Equities are primarily invested broadly in domestic and foreign companies across market capitalizations and industries. Fixed income securities are invested broadly, primarily in government treasury, corporate credit, mortgage backed and asset backed investments. Alternative investment allocations are included in selected plans to achieve greater portfolio diversity intended to reduce the overall volatility risk of the plans. Plan asset risks include longevity, inflation, and other changes in market conditions that could reduce the value of plan assets. Also, a decline in the yield of high quality corporate bonds may adversely affect discount rates resulting in an increase in DXC's pension and other post-retirement obligations. These risks, among others, could cause the plans’ funded status to deteriorate, resulting in an increased reliance on Company contributions. Derivatives are permitted although their current use is limited within traditional funds and broadly allowed within alternative funds. Derivatives are used for inflation risk management and within the liability driven investing strategy. The Company also has investments in insurance contracts to pay plan benefits in certain countries. Return on Assets The Company consults with internal and external advisors regarding the expected long-term rate of return on assets. The Company uses various sources in its approach to compute the expected long-term rate of return of the major asset classes expected in each of the plans. DXC utilizes long-term, asset class return assumptions of typically 30 years, which are provided by external advisors. Consideration is also given to the extent active management is employed in each asset class and also to management expenses. A single expected long-term rate of return is calculated for each plan by assessing the plan's expected asset allocation strategy, the benefits of diversification therefrom, historical excess returns from actively managed traditional investments, expected long-term returns for alternative investments and expected investment expenses. The resulting composite rate of return is reviewed by internal and external parties for reasonableness. Retirement Plan Discount Rate The U.K. discount rate is based on the yield curve approach using the U.K. Aon Hewitt GBP Single Agency AA Corporates-Only Curve. Defined Contribution Plans The Company sponsors defined contribution plans for substantially all U.S. employees and certain foreign employees. For certain plans, the Company will match employee contributions. The plans allow employees to contribute a portion of their earnings in accordance with specified guidelines. During fiscal 2023, 2022 and 2021, the Company contributed $203 million, $226 million and $221 million, respectively, to its defined contribution plans. As of March 31, 2023, plan assets included 2,580,378 shares of the Company’s common stock. Deferred Compensation Plans DXC sponsors two Deferred Compensation Plans, the “DXC Technology Company Deferred Compensation Plan” (the “DXC DCP”), and the Enterprise Services Executive Deferred Compensation Plan (the “ES DCP”). Both plans are non-qualified deferred compensation plans maintained for a select group of management, highly compensated employees and non-employee directors. The DXC DCP covers eligible employees who participated in CSC’s Deferred Compensation Plan prior to the HPES Merger. The ES DCP covers eligible employees who participated in the HPE Executive Deferred Compensation Plan prior to the HPES Merger. Both plans allow participating employees to defer the receipt of current compensation to a future distribution date or event above the amounts that may be deferred under DXC’s tax-qualified 401(k) plan, the DXC Technology Matched Asset Plan. Neither plan provides for employer contributions. As of April 3, 2017, the ES DCP does not admit new participants. Certain management and highly compensated employees are eligible to defer all, or a portion of, their regular salary that exceeds the limitation set forth in Internal Revenue Section 401(a)(17) and all or a portion of their incentive compensation. Non-employee directors are eligible to defer up to 100% of their cash compensation. The liability under the plan, which is included in other long-term liabilities in the Company's balance sheets, amounted to $29 million as of March 31, 2023 and $36 million as of March 31, 2022. The Company's expense under the Plan totaled $0 million and $2 million for fiscal 2023 and 2022 respectively.

In connection with the HPES Merger, the Company entered into a tax matters agreement with HPE. HPE generally will be responsible for tax liabilities arising prior to the HPES Merger, and DXC is liable to HPE for income tax receivables it receives related to pre-HPES Merger periods. Pursuant to the tax matters agreement, the Company recorded a $26 million tax indemnification receivable related to uncertain tax positions, a $53 million tax indemnification receivable related to other tax payables, and a $89 million tax indemnification payable related to other tax receivables. In connection with the spin-off of the Company's former U.S. public sector business (the "USPS Separation"), the Company entered into a tax matters agreement with Perspecta Inc. (including its successors and permitted assigns, "Perspecta"). The Company generally will be responsible for tax liabilities arising prior to the USPS Separation, and Perspecta is liable to the Company for income tax receivables related to pre-spin-off periods. Income tax liabilities transferred to Perspecta primarily relate to pre-HPES Merger periods, for which the Company is indemnified by HPE pursuant to the tax matters agreement between the Company and HPE. The Company remains liable to HPE for tax receivables transferred to Perspecta related to pre-HPES Merger periods. Pursuant to the tax matters agreement, the Company recorded a $18 million tax indemnification receivable from Perspecta related to other tax payables and a $6 million tax indemnification payable to Perspecta related to income tax and other tax receivables. In connection with the sale of the HPS business, the Company entered into a tax matters agreement with Dedalus. Pursuant to the tax matters agreement, the Company generally will be responsible for tax liabilities arising prior to the sale of the HPS business.

Fiscal Years Ended March 31, 2023 March 31, 2022 March 31, 2021 Statutory rate (21.0) % 21.0 % 21.0 % State income tax, net of federal tax (1.4) (6.9) 10.8 Foreign tax rate differential (2.3) 151.1 (198.4) Change in valuation allowances (1.3) (140.9) 239.3 Income tax and foreign tax credits (8.0) (15.2) (48.7) Change in uncertain tax positions 1.2 6.8 17.2 Withholding taxes 3.5 6.2 10.3 U.S. tax on foreign income 5.8 2.5 17.6 Excess tax benefits or expense for stock compensation 0.6 0.1 2.2 Capitalized transaction costs 0.2 0.2 0.5 Base erosion and transition taxes (9.1) 6.6 (0.7) Impact of business divestitures (7.6) 3.0 52.6 Granite trust capital loss — — (5.7) Indemnification costs 1.2 — — Other items, net 2.2 1.0 4.3 Effective tax rate (36.0) % 35.5 % 122.3 % In fiscal 2023, the ETR was primarily impacted by: • A reduction in base erosion and transition taxes, which increased income tax benefit and decreased the ETR by $81 million and 9.1%, respectively. • Income tax and foreign tax credits, which increased income tax benefit and decreased the ETR by $71 million and 8.0%, respectively, offset by tax expense on U.S. international tax inclusions which decreased tax benefit and increased the ETR by $51 million and 5.8%, respectively. • Non-taxable gains and losses on business divestitures, which increased income tax benefit and decreased the ETR by $67 million and 7.6%, respectively. In fiscal 2022, the ETR was primarily impacted by: • Income tax and foreign tax credits, which decreased income tax expense and decreased the ETR by $174 million and 15.2%, respectively. • Changes in Luxembourg losses that increased the ETR by $1,609 million and 141.0%, respectively, with an offsetting decrease in the ETR due to a decrease in the valuation allowance of the same amount. • Adjustments to uncertain tax positions that increased the overall income tax expense and the ETR by $78 million and 6.8%, respectively. In fiscal 2021, the ETR was primarily impacted by: • Impact of the HHS and other business divestitures, which increased tax expense and increased the ETR $344 million and 52.6%, respectively. The HHS tax gain increased tax expense and the ETR as the tax basis of assets sold, primarily goodwill, was lower than the book basis. • Continued losses in countries where we are recording a valuation allowance on certain deferred tax assets, primarily in Belgium, Denmark, Italy, France, Luxembourg, and U.S., and an impairment of the full German deferred tax asset, which increased income tax expense and increased the ETR by $1,565 million and 239.3%, respectively. • An increase in income tax and foreign tax credits, which decreased income tax expense and decreased the ETR by $319 million and 48.7%, respectively. • Local losses on investments in Luxembourg that increased the foreign rate differential and decreased the ETR by $1,226 million and 187.5%, respectively, with an offsetting increase in the ETR due to an increase in the valuation allowance of the same amount. • The Company recognized adjustments to uncertain tax positions that increased the overall income tax expense and the ETR by $112 million and 17.2%, respectively.

As of each reporting date, management weighs new evidence, both positive and negative, that could affect its view of the future realization of its net deferred tax assets. Objective verifiable evidence, which is historical in nature, carries more weight than subjective evidence, which is forward looking in nature. A valuation allowance has been recorded against deferred tax assets of approximately $2,064 million as of March 31, 2023, due to uncertainties related to the ability to utilize these assets. In assessing whether its deferred tax assets are realizable, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and adjusts the valuation allowance accordingly. The Company considers all available positive and negative evidence including future reversals of existing taxable temporary differences, taxable income in prior carryback years, projected future taxable income, tax planning strategies and recent financial operations. The net decrease in the valuation allowance of $66 million in fiscal 2023 was primarily due to a currency translation adjustment of $55 million. The following table provides information on the Company's various tax carryforwards: As of March 31, 2023 As of March 31, 2022 (in millions) Total With No Expiration With Expiration Expiration Dates Through Total With No Expiration With Expiration Expiration Dates Through Net operating loss carryforwards Federal $ 70 $ 70 $ — N/A $ 88 $ 88 $ — N/A State $ 463 $ 217 $ 246 2043 $ 589 $ 243 $ 346 2042 Foreign $ 9,164 $ 5,370 $ 3,794 2040 $ 9,368 $ 5,635 $ 3,733 2039 Tax credit carryforwards Federal $ 19 $ — $ 19 2043 $ 5 $ — $ 5 2042 State $ 4 $ — $ 4 2037 $ 5 $ 2 $ 3 2037 Foreign $ — $ — $ — N/A $ — $ — $ — N/A Capital loss carryforwards Federal $ 42 $ 42 $ — N/A $ 42 $ — $ 42 2026 State $ 46 $ 46 $ — N/A $ — $ — $ — N/A Foreign $ 199 $ 199 $ — N/A $ 199 $ 199 $ — N/A The Company also has federal and state 163(j) interest deduction carryforward attributes of approximately $23 million and $770 million, respectively, that have no expiration. The majority of our global unremitted foreign earnings have been taxed or would be exempt from U.S. tax upon repatriation. Such earnings and all current foreign earnings are not indefinitely reinvested. The following earnings are considered indefinitely reinvested: approximately $484 million that could be subject to U.S. federal tax when repatriated to the U.S. under section 1.245A-5(b) of the final Treasury regulations; and approximately $200 million of our accumulated earnings in India. A portion of these indefinitely reinvested earnings may be subject to foreign and U.S. state tax consequences when remitted. The Company will continue to evaluate its position in the future based on its future strategy and cash needs. The Company accounts for income tax uncertainties in accordance with ASC 740 Income Taxes, which prescribes a recognition threshold and measurement criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more likely than not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more likely than not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. ASC 740 also provides guidance on the accounting for and disclosure of liabilities for uncertain tax positions, interest and penalties. In accordance with ASC 740, the Company’s liability for uncertain tax positions was as follows: Fiscal Years Ended (in millions) March 31, 2023 March 31, 2022 Tax $ 399 $ 422 Interest 79 76 Penalties 18 20 Offset to receivable (91) (104) Net of tax attributes (1) (1) Total $ 404 $ 413 The following table summarizes the activity related to the Company’s uncertain tax positions (excluding interest and penalties and related tax attributes): Fiscal Years Ended (in millions) March 31, 2023 March 31, 2022 March 31, 2021 Balance at beginning of fiscal year $ 422 $ 354 $ 253 Gross increases related to prior year tax positions 31 61 60 Gross decreases related to prior year tax positions (17) (16) (30) Gross increases related to current year tax positions 8 93 102 Settlements and statute of limitation expirations (43) (33) (36) Acquisitions and dispositions — (36) 6 Foreign exchange and others (2) (1) (1) Balance at end of fiscal year $ 399 $ 422 $ 354 The Company’s liability for uncertain tax positions at March 31, 2023, March 31, 2022, and March 31, 2021, includes $368 million, $393 million and $316 million, respectively, related to amounts that, if recognized, would affect the effective tax rate (excluding related interest and penalties). The increase related to prior year tax positions primarily relates to an increase in foreign tax credits. The change in settlements and statute of limitation expirations primarily relates to amounts agreed to with tax authorities. The Company recognizes interest accrued related to uncertain tax positions and penalties as a component of income tax expense. During the year ended March 31, 2023, the Company had a net increase in interest expense of $3 million ($1 million net of tax) and a net decrease in accrued expense for penalties of $2 million and, as of March 31, 2023, recognized a liability for interest of $79 million ($61 million net of tax) and penalties of $18 million. During the year ended March 31, 2022, the Company had net decrease in interest expense of $1 million ($1 million net of tax) and net decrease in accrued expense for penalties of $2 million, and as of March 31, 2022, recognized a liability for interest of $76 million ($60 million net of tax) and penalties of $20 million. During the year ended March 31, 2021, the Company had a net increase in interest of $1 million ($(1) million net of tax) and a net increase in accrued expense for penalties of $1 million and as of March 31, 2021, recognized a liability for interest of $46 million ($39 million net of tax) and penalties of $22 million. The Company is currently under examination in several tax jurisdictions. A summary of the tax years that remain subject to examination in certain of the Company’s major tax jurisdictions are: Jurisdiction: Tax Years that Remain Subject to Examination (Fiscal Year Ending): United States – Federal 2009 and forward United States – Various States 2009 and forward Canada 2010 and forward France 2016 and forward Germany 2010 and forward India 2001 and forward U. K. 2018 and forward Tax Examinations The Internal Revenue Service (the “IRS”) has examined, or is examining, the Company’s federal income tax returns for fiscal 2009 through the tax year ended October 31, 2018. With respect to CSC’s fiscal 2009 through 2017 federal tax returns, the Company participated in settlement negotiations with the IRS Office of Appeals. The IRS examined several issues for these tax years that resulted in various audit adjustments. The Company and the IRS Office of Appeals have settled various audit adjustments, and we disagree with the IRS’ disallowance of certain losses and deductions resulting from restructuring costs and tax planning strategies in previous years. As we believe we will ultimately prevail on the technical merits of the disagreed items and are challenging them in the U.S. Tax Court, these matters are not fully reserved and would result in incremental federal and state tax expense and cash tax payments of approximately $477 million (including estimated interest and penalties) for the unreserved portion of these items if we do not prevail. We have received notices of deficiency with respect to fiscal 2009, 2010, 2011 and 2013 and have timely filed petitions with the U.S. Tax Court. We do not expect the U.S. Tax Court matters to be resolved in the next 12 months. The Company’s fiscal years 2009, 2010, 2011 and 2013 are in the U.S. Tax Court, and consequently these years will remain open until such proceedings have concluded. The statute of limitations on assessments related to a refund claim for fiscal year 2012 is open through February 28, 2025. The Company has agreed to extend the statute of limitations for fiscal and tax return years 2014 through 2020 to September 30, 2024. The Company expects to reach resolution for fiscal and tax return years 2009 through 2020 no earlier than fiscal 2025. The Company may settle certain other tax examinations for different amounts than the Company has accrued as uncertain tax positions. Consequently, the Company may need to accrue and ultimately pay additional amounts or pay lower amounts than previously estimated and accrued when positions are settled in the future. The Company believes the outcomes that are reasonably possible within the next 12 months to result in a reduction in its liability for uncertain tax positions, excluding interest, penalties, and tax carryforwards, would be approximately $16 million.

Equity [Abstract]
Stockholders' Equity	Stockholders' Equity Description of Capital Stock The Company has authorized share capital consisting of 750,000,000 shares of common stock, par value $0.01 per share, and 1,000,000 shares of preferred stock, par value $0.01 per share. Each share of common stock is equal in all respects to every other share of common stock of the Company. Each share of common stock is entitled to one vote per share at each annual or special meeting of stockholders for the election of directors and upon any other matter coming before such meeting. Subject to all the rights of the preferred stock, dividends may be paid to holders of common stock as and when declared by the Board of Directors (the "Board"). The Company's charter requires that preferred stock must be all of one class but may be issued from time to time in one or more series, each of such series to have such full or limited voting powers, if any, and such designations, preferences and relative, participating, optional or other special rights or qualifications, limitations or restrictions as provided in a resolution adopted by the Board. Each share of preferred stock will rank on a parity with each other share of preferred stock, regardless of series, with respect to the payment of dividends at the respectively designated rates and with respect to the distribution of capital assets according to the amounts to which the shares of the respective series are entitled. Share Repurchase Program On April 3, 2017, DXC announced the establishment of a share repurchase program approved by the Board with an initial authorization of up to $2.0 billion for future repurchases of outstanding shares of DXC common stock. On November 8, 2018, DXC announced that its Board approved an incremental $2.0 billion share repurchase authorization. Under these approved share repurchase plans, on February 2, 2022, we announced our intention and subsequently completed the repurchase of $1.0 billion of our outstanding shares of common stock in the open market prior to the issuance of this Annual Report on Form 10-K. On May 18, 2023, DXC announced that its Board approved an incremental $1.0 billion share repurchase authorization. Share repurchases may be made from time to time through various means, including in open market purchases, 10b5-1 plans, privately-negotiated transactions, accelerated stock repurchases, block trades and other transactions, in compliance with Rule 10b-18 under the Exchange Act of 1934, as amended, as well as, to the extent applicable, other federal and state securities laws and other legal requirements. The timing, volume, and nature of share repurchases pursuant to the share repurchase plan are at the discretion of management and may be suspended or discontinued at any time. The shares repurchased are retired immediately and included in the category of authorized but unissued shares. The excess of purchase price over par value of the common shares is allocated between additional paid-in capital and retained earnings. There was no share repurchase activity during fiscal 2021. The details of shares repurchased during fiscal 2023 and 2022 are shown below: Fiscal Year Number of shares repurchased Average Price Per Share Amount 2023 Open market purchases 24,436,738 $27.78 $ 679 2023 Total 24,436,738 $27.78 $ 679 2022 Open market purchases 18,818,934 $33.67 $ 634 2022 Total 18,818,934 $33.67 $ 634 Treasury Stock Transactions In fiscal 2023, 2022 and 2021 the Company accepted 0, 4,614 and 4,050 shares of its common stock, respectively, in lieu of cash in connection with the exercise of stock options. In fiscal 2023, 2022 and 2021, the Company accepted 455,513, 415,438 and 305,269 shares of its common stock, respectively, in lieu of cash in connection with the tax withholdings associated with the release of common stock upon vesting of restricted stock and RSUs. As a result, the Company holds 3,333,592 treasury shares as of March 31, 2023. Dividends The Board has suspended the Company’s cash dividend payment beginning in the first quarter of fiscal 2021 to preserve cash and enhance financial flexibility in the current environment. As of March 31, 2023 the Company does not intend to reinstate its quarterly cash dividends.

Stock Incentive Plans

Stock Incentive Plans	12 Months Ended

Share-Based Payment Arrangement [Abstract]
Stock Incentive Plans	Stock Incentive Plans Equity Plans The Compensation Committee of the Board has broad authority to grant awards and otherwise administer the DXC Employee Equity Plan. The plan became effective March 30, 2017 and will continue in effect for a period of 10 years thereafter, unless terminated earlier by the Board. The Board has the authority to amend the plan in such respects as it deems desirable, subject to approval of DXC’s stockholders for material modifications. Restricted stock units ("RSUs") represent the right to receive one share of DXC common stock upon a future settlement date, subject to vesting and other terms and conditions of the award, plus any dividend equivalents accrued during the award period. In general, if the employee’s status as a full-time employee is terminated prior to the vesting of the RSU grant in full, then the RSU grant is automatically canceled on the termination date and any unvested shares and dividend equivalents are forfeited. Certain executives were awarded service-based "career share" RSUs for which the shares are settled over the 10 anniversaries following the executive's separation from service as a full-time employee, provided the executive complies with certain non-competition covenants during that period. The Company also grants PSUs, which generally vest over a period of three years. The number of PSUs that ultimately vest is dependent upon the Company’s achievement of certain specified financial performance criteria over a 3-year period. If the specified performance criteria are met, awards are settled for shares of DXC common stock and dividend equivalents upon the filing with the SEC of the Annual Report on Form 10-K for the last fiscal year of the performance period. Certain PSU awards include the potential for up to 25% of the shares granted to be earned after the first and second fiscal years if certain of the Company's performance targets are met early, subject to vesting based on the participant's continued employment through the end of the three-year performance period. Beginning in fiscal 2021, DXC issued awards that are considered to have a market condition. A Monte Carlo simulation model was used for the valuation of the grants. Settlement of shares for these PSU awards will be made at the end of the third fiscal year subject to certain compounded annual growth rates of the stock price and continued employment through the last day of the third fiscal year. The terms of the DXC Director Equity Plan allow DXC to grant RSU awards to non-employee directors of DXC. Such RSU awards vest in full at the earlier of (i) the first anniversary of the grant date or (ii) the next annual meeting date, and are automatically redeemed for DXC common stock and dividend equivalents either at that time or, if an RSU deferral election form is submitted, upon the date or event elected by the director. Distributions made upon a director’s separation from the Board may occur in either a lump sum or in annual installments over periods of 5, 10, or 15 years, per the director’s election. In addition, RSUs vest in full upon a change in control of DXC. The DXC Share Purchase Plan allows DXC’s employees located in the U.K. to purchase shares of DXC’s common stock at the fair market value of such shares on the applicable purchase date. There were 35,721 shares purchased under this plan during fiscal 2023. The Board has reserved for issuance shares of DXC common stock, par value $0.01 per share, under each of the plans as detailed below: As of March 31, 2023 Reserved for issuance Available for future grants DXC Employee Equity Plan 51,200,000 29,094,643 DXC Director Equity Plan 745,000 295,551 DXC Share Purchase Plan 250,000 90,196 Total 52,195,000 29,480,390 The Company recognized share-based compensation expense for fiscal 2023, 2022 and 2021 as follows: Fiscal Years Ended (in millions) March 31, 2023 March 31, 2022 March 31, 2021 Total share-based compensation cost $ 108 $ 101 $ 56 Related income tax benefit $ 18 $ 14 $ 6 Total intrinsic value of options exercised $ 1 $ 8 $ 1 Tax benefits from exercised stock options and awards $ 12 $ 17 $ 6 As of March 31, 2023, total unrecognized compensation expense related to unvested DXC RSUs, net of expected forfeitures was $141 million, respectively.

See Note 14 - "Pension and Other Benefit Plans" for additional information. • a foreign currency gain of $15 million in fiscal 2023 versus a $13 million loss in fiscal 2022 primarily due to movements of exchange rates on our foreign currency denominated assets and liabilities, related hedges including forward contracts to manage our exposure to economic risk, and the cost of our hedging program. • a $2 million increase in gains from sales of assets.

Segment Measures The following table summarizes operating results regularly provided to the CODM by reportable segment and a reconciliation to the financial statements: (in millions) GBS GIS Total Reportable Segments All Other Totals Fiscal Year Ended March 31, 2023 Revenues $ 6,960 $ 7,470 $ 14,430 $ — $ 14,430 Segment Profit $ 912 $ 507 $ 1,419 $ (262) $ 1,157 Depreciation and amortization (1) $ 165 $ 853 $ 1,018 $ 99 $ 1,117 Fiscal Year Ended March 31, 2022 Revenues $ 7,598 $ 8,667 $ 16,265 $ — $ 16,265 Segment Profit $ 1,160 $ 475 $ 1,635 $ (260) $ 1,375 Depreciation and amortization (1) $ 180 $ 991 $ 1,171 $ 112 $ 1,283 Fiscal Year Ended March 31, 2021 Revenues $ 8,336 $ 9,393 $ 17,729 $ — $ 17,729 Segment Profit $ 1,120 $ 245 $ 1,365 $ (263) $ 1,102 Depreciation and amortization (1) $ 212 $ 1,122 $ 1,334 $ 106 $ 1,440 (1) Depreciation and amortization as presented excludes amortization of acquired intangible assets of $402 million, $434 million, and $530 million for fiscal 2023, 2022, and 2021, respectively. Reconciliation of Reportable Segment Profit to Consolidation The Company's management uses segment profit as the measure for assessing performance of its segments. Segment profit is defined as segment revenues less cost of services, segment selling, general and administrative, depreciation and amortization, and other income (excluding the movement in foreign currency exchange rates on DXC's foreign currency denominated assets and liabilities and the related economic hedges). The Company does not allocate to its segments certain operating expenses managed at the corporate level. These unallocated costs generally include certain corporate function costs, stock-based compensation expense, pension and OPEB actuarial and settlement gains and losses, restructuring costs, transaction, separation, and integration-related costs and amortization of acquired intangible assets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company signed long-term purchase agreements with certain software, hardware, telecommunication and other service providers to obtain favorable pricing and terms for services and products that are necessary for the operations of business activities. Under the terms of these agreements, the Company is contractually committed to purchase specified minimum amounts within defined time periods. If the Company does not meet the specified minimums, the Company would have an obligation to pay the service provider all, or a portion, of the shortfall. Minimum purchase commitments as of March 31, 2023 were as follows: Fiscal year Minimum Purchase Commitment (in millions) 2024 $ 460 2025 246 2026 230 2027 9 Total $ 945 In the normal course of business, the Company may provide certain customers with financial performance guarantees, and at times performance letters of credit or surety bonds. In general, the Company would only be liable for the amounts of these guarantees in the event that non-performance by the Company permits termination of the related contract by the Company’s customer. The Company believes it is in compliance with its performance obligations under all service contracts for which there is a financial performance guarantee, and the ultimate liability, if any, incurred in connection with these guarantees will not have a material adverse effect on its consolidated results of operations or financial position. The Company also uses stand-by letters of credit, in lieu of cash, to support various risk management insurance policies. These letters of credit represent a contingent liability and the Company would only be liable if it defaults on its payment obligations on these policies. The following table summarizes the expiration of the Company’s financial guarantees and stand-by letters of credit outstanding as of March 31, 2023: (in millions) Fiscal 2024 Fiscal 2025 Fiscal 2026 and Thereafter Totals Surety bonds $ 88 $ 5 $ 43 $ 136 Letters of credit 89 29 615 733 Stand-by letters of credit 78 — 8 86 Totals $ 255 $ 34 $ 666 $ 955 The Company generally indemnifies licensees of its proprietary software products against claims brought by third parties alleging infringement of their intellectual property rights, including rights in patents (with or without geographic limitations), copyrights, trademarks and trade secrets. DXC’s indemnification of its licensees relates to costs arising from court awards, negotiated settlements, and the related legal and internal costs of those licensees. The Company maintains the right, at its own cost, to modify or replace software in order to eliminate any infringement. The Company has not incurred any significant costs related to licensee software indemnification. Contingencies Forsyth, et al. v. HP Inc. and Hewlett Packard Enterprise: On August 18, 2016, this purported class and collective action was filed in the U.S. District Court for the Northern District of California, against HP and HPE alleging violations of the Federal Age Discrimination in Employment Act (“ADEA”) and California state law, in connection with workforce reductions that occurred in or after August 2012 in California, and in or after as early as December 2014 in other U.S. locations. Former business units of HPE now owned by the Company and former business units of the Company now owned by Peraton (formerly Perspecta), may be proportionately liable for any recovery by plaintiffs in this matter. In December 2020, Plaintiffs filed a motion for preliminary certification of the collective action, which Defendants opposed. In April 2021, the court granted Plaintiffs’ motion for preliminary certification and lifted the previously imposed stay of the action. In November 2021, notice was sent to putative members of the ADEA collectives regarding participation in the case. In February 2022, the notice period closed. The case is currently stayed. Securities Litigation: Previously disclosed securities litigation matters have been dismissed, with one case remaining, in the Superior Court of the State of California. On August 20, 2019, a purported class action lawsuit was filed in the Superior Court of the State of California, County of Santa Clara, against the Company, directors of the Company, and a former officer of the Company, among other defendants. The action asserts claims under Sections 11, 12 and 15 of the Securities Act of 1933, as amended, and is premised on allegedly false and/or misleading statements, and alleged non-disclosure of material facts, regarding the Company’s prospects and expected performance. The putative class of plaintiffs includes all persons who acquired shares of the Company’s common stock pursuant to the offering documents filed with the Securities and Exchange Commission in connection with the April 2017 transaction that formed DXC. The State of California action had been stayed pending the outcome of the substantially similar federal action filed in the United States District Court for the Northern District of California. The federal action was dismissed with prejudice in December 2021. Thereafter, the state court lifted the stay and entered an order permitting additional briefing by the parties. In March 2022, Plaintiffs filed an amended complaint, which the Company moved to dismiss. In August 2022, the Court granted the Company’s motion to dismiss, but permitted Plaintiffs to amend and refile their complaint. In September 2022, Plaintiffs filed a second amended complaint, which the Company moved to dismiss. In January 2023, the Court issued an order denying the Company’s motion to dismiss the second amended complaint. In March 2023, the Court entered a scheduling order setting a trial date for September 2025. The case is now in discovery. The Company believes that the final remaining lawsuit described above is also without merit, and intends to vigorously defend it. Tax Examinations: The Company is under IRS examination in the U.S. on its federal income tax returns for certain fiscal years and is in disagreement with the IRS on certain tax positions, which are currently being contested in the U.S. Tax Court. For more detail, see Note 15 - "Income Taxes" for further information. SEC Matter : In December 2019, the Company received a request for voluntary production of information in connection with an informal investigation by the U.S. Securities and Exchange Commission. The primary focus of the investigation was the Company’s historical reporting related to its non-GAAP adjustment for “transaction, separation, and integration-related costs,” including whether the disclosure the Company previously used to describe the non-GAAP adjustment was sufficiently broad to cover certain expenses the Company included as transaction, separation, and integration-related costs. The non-GAAP costs at issue primarily consisted of expenses associated with the business combination that formed DXC in 2017. The Company cooperated fully with the SEC’s informal investigation, and the new management team appointed beginning in September of 2019 proactively clarified and expanded the disclosure of the Company’s non-GAAP transaction, separation, and integration-related costs. In addition, the new management team significantly reduced the transaction, separation, and integration-related costs. In September 2022, the Company accrued $8 million, representing its estimate of the settlement costs based on its discussions with the SEC at that time. In March 2023, the Company entered into an Offer of Settlement with the SEC and a Cease-and-Desist Order was entered. The Company agreed to pay a civil penalty of $8 million and to implement certain remedial measures related to the Company’s non-GAAP policies and procedures within 120 days. The Company has paid the civil penalty and intends to fully implement the remedial measures within the time provided. This matter is otherwise closed. OFAC Matter: In August 2022, the Company submitted an initial notification of voluntary self-disclosure to the U.S. Department of the Treasury, Office of Foreign Assets Control (“OFAC”) regarding potential violations of U.S. sanctions on Russia. The self-disclosure pertains to the Company’s sale of Luxoft’s Russia business to IBS Holding LLC in April 2022, as part of the Company’s exit from the Russian market following Russia’s invasion of Ukraine. The Company has also submitted an initial notification of voluntary self-disclosure to the U.S. Department of Commerce, Bureau of Industry and Security (“BIS”) regarding potential export control violations in connection with its exit from the Russian market. The Company’s review of potential sanctions violations is ongoing, and the Company may make further disclosures to relevant agencies as its review continues. In addition to the matters noted above, the Company is currently subject in the normal course of business to various claims and contingencies arising from, among other things, disputes with customers, vendors, employees, contract counterparties and other parties, as well as securities matters, environmental matters, matters concerning the licensing and use of intellectual property, and inquiries and investigations by regulatory authorities and government agencies. Some of these disputes involve or may involve litigation. The financial statements reflect the treatment of claims and contingencies based on management’s view of the expected outcome. DXC consults with outside legal counsel on issues related to litigation and regulatory compliance and seeks input from other experts and advisors with respect to matters in the ordinary course of business. Although the outcome of these and other matters cannot be predicted with certainty, and the impact of the final resolution of these and other matters on the Company’s results of operations in a particular subsequent reporting period could be material and adverse, management does not believe based on information currently available to the Company, that the resolution of any of the matters currently pending against the Company will have a material adverse effect on the financial position of the Company or the ability of the Company to meet its financial obligations as they become due. Unless otherwise noted, the Company is unable to determine at this time a reasonable estimate of a possible loss or range of losses associated with the foregoing disclosed contingent matters.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Mar. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In order to make this report easier to read, DXC refers throughout to (i) the Consolidated Financial Statements as the “financial statements,” (ii) the Consolidated Statements of Operations as the “statements of operations,” (iii) the Consolidated Statement of Comprehensive (Loss) Income as the "statements of comprehensive income," (iv) the Consolidated Balance Sheets as the “balance sheets,” and (v) the Consolidated Statements of Cash Flows as the “statements of cash flows.” In addition, references are made throughout to the numbered Notes to the Consolidated Financial Statements (“Notes”) in this Annual Report on Form 10-K.
Use of Estimates	Use of Estimates The preparation of the financial statements, in accordance with GAAP, requires the Company's management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosure of contingent assets and liabilities. The Company bases its estimates on assumptions regarding historical experience, currently available information, and anticipated developments that it believes are reasonable and appropriate. However, because the use of estimates involves an inherent degree of uncertainty, actual results could differ from those estimates. Estimates are used for, but not limited to, contracts accounted for using the percentage-of-completion method, cash flows used in the evaluation of impairment of goodwill and other long-lived assets, reserves for uncertain tax positions, valuation allowances on deferred tax assets, loss accruals for litigation, and obligations related to our pension plans. In the opinion of the Company's management, the accompanying financial statements contain all adjustments necessary, including those of a normal recurring nature, to fairly present the financial statements.
Leases	Leases The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether DXC obtains substantially all economic benefits from and has the ability to direct the use of the asset. Leased assets classified as operating leases are included in operating right-of-use ("ROU") assets, net, with the associated liabilities included in current operating lease liabilities and non-current operating lease liabilities in DXC's balance sheets. Finance leases are included in property and equipment, net, short-term debt and current maturities of long-term debt and long-term debt, net of current maturities in DXC's balance sheets. Leased assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Lease liabilities are recognized at commencement based on the present value of fixed or in-substance fixed lease payments over the lease term. Leased assets are recognized at commencement based upon the leased liability plus any lease payments made at or before lease commencement and excluding any lease incentives. As most of the Company's leases do not provide an implicit rate, DXC uses its incremental borrowing rate based on the information available at commencement to determine the present value of lease payments. The incremental borrowing rate is the rate of interest that DXC would have to pay to borrow, on a collateralized basis, an amount equal to the lease payments, in a similar economic environment and over a similar term. The rate is dependent on several factors, including the lease term, currency of the lease payments and the Company's credit ratings. The Company's lease terms may include options to extend or terminate the lease. Leased assets and lease liabilities include these options when it is reasonably certain that they will be exercised. Lease arrangements generally do not contain any residual value guarantees or material restrictive covenants. Operating lease expense, which includes interest, is recognized on a straight-line basis over the lease term with variable payments, primarily related to the operational costs for the Company's leased real estate for offices, which are recognized as incurred. Assets obtained under finance leases are recorded as fixed assets and depreciated over the shorter of the depreciable life of the asset or the lease term.
Revenue Recognition	Revenue Recognition The Company's primary service offerings are information technology outsourcing, other professional services, or a combination thereof. Revenues are recognized when control of the promised goods or services is transferred to DXC's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. DXC determines revenue recognition through the five-step model as follows: • Identification of the contract, or contracts, with a customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, the Company satisfies a performance obligation DXC's IT outsourcing ("ITO") arrangements typically reflect a single performance obligation that comprises a series of distinct services which are substantially the same and provided over a period of time using the same measure of progress. Revenue derived from these arrangements is recognized over time based upon the level of services delivered in the distinct periods in which they are provided based on time increments. When other parties are involved in providing goods or services as part of our customer arrangements, DXC recognizes revenue on a gross basis as a principal when it controls goods or services before they are transferred to the customer. In addition, the Company reports revenue net of any revenue-based taxes assessed by a governmental authority that are imposed on and concurrent with specific revenue-producing transactions, such as sales taxes and value-added taxes. DXC's contracts often include upfront fees billed for activities to familiarize DXC with the customers' operations, take control over their administration and operation, and adapt them to DXC's solutions. Upfront fees are generally recognized ratably over the contract period, which approximates the manner in which the services are provided. These activities typically do not qualify as performance obligations, and the related revenues are allocated to the relevant performance obligations and recognized ratably over time as the performance obligation is satisfied during the period in which DXC provides the related service, which is typically the life of the contract. Software transactions that include multiple performance obligations are described below. For contracts with multiple performance obligations, DXC allocates the contract’s transaction price to each performance obligation based on the relative standalone selling price of each distinct good or service in the contract. Other than software sales involving multiple performance obligations, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which the Company forecasts its expected costs of satisfying a performance obligation and then adds an appropriate margin for that distinct good or service. DXC's ITO arrangements may also contain embedded leases for equipment used to fulfill services. A contract with a customer includes an embedded lease when DXC grants the customer a right to control the use of an identified asset for a period of time in exchange for consideration. Embedded leases with customers are typically recognized either as sales type leases in which revenue and co st of sales is recognized upon lease commencement; or they may be recognized as operating leases in which revenue is recognized over the usage period. Where a contract contains an embedded lease, the contract’s transaction price is allocated to the contract performance obligations and the lease component based upon the relative standalone selling price. The transaction price of a contract is determined based on fixed and variable consideration. Variable consideration related to the Company’s ITO offerings often includes volume-based pricing that is allocated to the distinct days of the services to which the variable consideration pertains. However, in certain cases, estimates of variable consideration, including penalties, contingent milestone payments and rebates are necessary. The Company only includes estimates of variable consideration in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. These judgments involve consideration of historical and expected experience with the customer and other similar customers, and the facts and circumstances specific to the arrangement. Contracts with our customers may be modified over the course of the contract term and we may change the scope, price or both of the existing contracts. Contract modifications are reviewed to determine whether they should be accounted for as part of the original contract, the termination of an existing contract and the creation of a new contract, or as a separate contract. Contract modifications are a separate contract when the modification provides additional goods and services that are distinct and the transaction price is at the standalone selling price. If the contract modification is part of the existing contract, a cumulative adjustment to revenue is recorded. If the contract modification represents the termination of the existing contract and the creation of a new contract, the modified transaction price is allocated to the prospective performance obligations and any embedded lease components. If a contract modification modifies an embedded lease component and the modification is not accounted for as a separate contract, the classification of the lease is reassessed. The Company generally provides its services under time and materials contracts, unit-price contracts, fixed-price contracts, and software contracts for which revenue is recognized in the following manner: Time and materials contracts . Revenue is recognized over time at agreed-upon billing rates when services are provided. Unit-price contracts. Revenue is recognized over time based on unit metrics multiplied by the agreed-upon contract unit price or when services are delivered. Fixed-price contracts. For certain fixed-price contracts, revenue is recognized over time using a method that measures the extent of progress towards completion of a performance obligation, generally using a cost-input method (referred to as the percentage-of-completion cost-to-cost method). Under the percentage-of-completion cost-to-cost method, revenue is recognized based on the proportion of total cost incurred to estimated total costs at completion. A performance obligation's estimate at completion includes all direct costs such as materials and labor. If output or input measures are not available or cannot be reasonably estimated, revenue is deferred until progress can be measured and costs are not deferred unless they meet the criteria for capitalization. Under the percentage-of-completion cost-to-cost method, progress towards completion is measured based on costs incurred as a proportion of estimated total costs. Profit in a given period is reported at the estimated profit margin to be achieved on the overall contract. If estimated total costs at completion exceed estimated revenue for a contract under the percentage-of-completion cost-to-cost method, the loss is recognized in the quarter it first becomes probable and reasonably estimable. Software contracts. Certain of DXC's arrangements involve the sale of DXC proprietary software, post-contract customer support, and other software-related services. The standalone selling price generally is determined for each performance obligation using an adjusted market assessment approach based on the price charged where each deliverable is sold separately. In certain limited cases (typically for software licenses) when the historical selling price is highly variable, the residual approach is used. This approach allocates revenue to the performance obligation equal to the difference between the total transaction price and the observable standalone selling prices for the other performance obligations. Revenue from distinct software licenses is recognized at a point in time when the customer can first use the software license. If significant customization is required, software revenue is recognized as the related software customization services are performed in accordance with the percentage-of-completion method described above. Revenue for post-contract customer support and other software services is recognized over time as those services are provided . Practical Expedients DXC does not adjust the promised amount of consideration for the effects of a significant financing component when the period between when DXC transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. Contract Balances The timing of revenue recognition, billings and cash collections results in accounts receivable (billed receivables, unbilled receivables and contract assets) and deferred revenue and advance contract payments (contract liabilities) on the Company's balance sheets. In arrangements that contain an element of customized software solutions, amounts are generally billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g. monthly) or upon achievement of certain contractual milestones. Generally, billing occurs subsequent to revenue recognition, sometimes resulting in contract assets if the related billing is conditional upon more than just the passage of time. However, the Company sometimes receives advances or deposits from customers, before revenue is recognized, which results in the generation of contract liabilities. Payment terms vary by type of product or service being provided as well as by customer, although the term between invoicing and when payment is due is generally an insignificant period of time. Costs to Obtain a Contract Certain sales commissions earned by the Company's sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The majority of sales commissions are paid based on the achievement of quota-based targets. These costs are deferred and amortized on a straight-line basis over an average period of benefit determined to be five years. The Company determined the period of benefit considering the length of its customer contracts, its technology, and other factors. Some commission payments are not capitalized because they are expensed during the fiscal year as the related revenue is recognized. Capitalized sales commissions costs are classified within other assets and amortized in selling, general and administrative expenses. Costs to Fulfill a Contract Certain contract setup costs incurred upon initiation or renewal of an outsourcing contract that generate or enhance resources to be used in satisfying future performance obligations are capitalized when they are deemed recoverable. Judgment is applied to assess whether contract setup costs are capitalizable. Costs that generate or enhance resources often pertain to activities that enhance the capabilities of the services, improve customer experience, and establish a more effective and efficient IT environment. The Company recognizes these transition and transformation contract costs as other assets, which are amortized over the respective contract life.
Pension and Other Benefit Plans	Pension and Other Benefit Plans The Company accounts for its pension, other post-retirement benefit ("OPEB"), defined contribution and deferred compensation plans using the guidance of ASC 710 "Compensation – General" and ASC 715 "Compensation – Retirement Benefits." The Company recognizes actuarial gains and losses and changes in fair value of plan assets in earnings at the time of plan remeasurement as a component of net periodic benefit expense. Typically plan remeasurement occurs annually during the fourth quarter of each fiscal year. The remaining components of pension and OPEB expense, primarily current period service and interest costs and expected return on plan assets, are recorded on a quarterly basis. Inherent in the application of the actuarial methods are key assumptions, including, but not limited to, discount rates, expected long-term rates of return on plan assets, mortality rates, rates of compensation increases, and medical cost trend rates. Company management evaluates these assumptions annually and updates assumptions as necessary. The fair value of assets is determined based on the prevailing market prices or estimated fair value of investments when quoted prices are not available.
Software Development Costs	Software Development Costs After establishing technological feasibility, and until such time as the software products are available for general release to customers, the Company capitalizes costs incurred to develop commercial software products to be sold, leased or otherwise marketed. Costs incurred to establish technological feasibility are charged to expense as incurred. Enhancements to software products are capitalized where such enhancements extend the life or significantly expand the marketability of the products. Amortization of capitalized software development costs is determined separately for each software product. Annual amortization expense is calculated based on the greater of the ratio of current gross revenues for each product to the total of current and anticipated future gross revenues for the product or the straight-line amortization method over the estimated useful life of the product. Unamortized capitalized software costs associated with commercial software products are periodically evaluated for impairment on a product-by-product basis by comparing the unamortized balance to the product’s net realizable value. The net realizable value is the estimated future gross revenues from that product reduced by the related estimated future costs. When the unamortized balance exceeds the net realizable value, the unamortized balance is written down to the net realizable value and an impairment charge is recorded. The Company capitalizes costs incurred to develop internal-use computer software during the application development stage. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Internal and external costs incurred in connection with development of upgrades or enhancements that result in additional functionality are also capitalized. Capitalized costs associated with internal-use software are amortized on a straight-line basis over the estimated useful life of the software. Purchased software is capitalized and amortized over the estimated useful life of the software. Internal-use software assets are evaluated for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
Share-Based Compensation	Share-Based Compensation Share-based awards are accounted for under the fair value method. The Company provides different forms of share-based compensation to its employees and non-employee directors. This generally includes restricted stock units ("RSUs"), including performance-based restricted stock units ("PSUs"). The fair value of the awards is determined on the grant date, based on the Company's closing stock price. For awards settled in shares, the Company recognizes compensation expense based on the grant-date fair value net of estimated forfeitures over the vesting period. For awards settled in ca sh, the Company recognizes compensation expense based on the fair value at each reporting date net of estimated forfeitures.
Goodwill Impairment Analysis	Goodwill Impairment Analysis The Company tests goodwill for impairment on an annual basis as of the first day of the second fiscal quarter and between annual tests if circumstances change, or if an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company has defined its reporting units as its reportable segments. A significant amount of judgment is involved in determining whether an event indicating impairment has occurred between annual testing dates. Such indicators include: a significant decline in the Company's stock price, a significant decline in expected future cash flows, a significant adverse change in legal factors or in the business climate, unanticipated competition, the disposal of a significant component of a reporting unit and the testing for recoverability of a significant asset group within a reporting unit. The Company initially assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. This qualitative assessment considers all relevant factors specific to the reporting units, including macroeconomic conditions, industry and market considerations, overall financial performance, and relevant entity-specific events. If the Company determines that it is not more likely than not that the carrying amount for a reporting unit is less than its fair value, then subsequent quantitative goodwill impairment testing is not required. If the Company determines that it is more likely than not that the carrying amount for a reporting unit is greater than its fair value, then it proceeds with a subsequent quantitative goodwill impairment test. The Company has the option to bypass the initial qualitative assessment stage and proceed directly to the quantitative goodwill impairment test. The quantitative goodwill impairment test compares each reporting unit’s fair value to its carrying value. If the reporting unit’s fair value exceeds its carrying value, no further procedures are required. However, if a reporting unit’s fair value is less than its carrying value, then an impairment charge is recorded in the amount of the excess . When the Company performs the quantitative goodwill impairment test for a reporting unit, it estimates the fair value of the reporting unit using a combination of an income approach and a market approach. The income approach utilizes a discounted cash flow analysis in which the estimated future cash flows and terminal values for each reporting unit are discounted to present value using a discount rate. Cash flow projections are based on management's estimates of economic and market conditions, which drive key assumptions of revenue growth rates, operating margins, capital expenditures and working capital requirements. The discount rate is based on the weighted-average cost of capital and may be adjusted for the relevant risks associated with business-specific characteristics and any uncertainty related to a reporting unit’s ability to execute on the projected future cash flows. The market approach estimates fair value by applying performance-metric multiples to the reporting unit's prior and expected operating performance. The multiples are derived from comparable publicly traded companies that have operating and investment characteristics similar to those of the reporting unit. If the fair value of the reporting unit derived using one approach is significantly different from the fair value estimate using the other approach, the Company reevaluates its assumptions used in the two models. Assumptions are modified as considered appropriate under the circumstances until the two models yield similar and reasonable results. The fair values determined by the market approach and income approach, as described above, are weighted to determine the fair value for each reporting unit.
Fair Value	Fair Value The Company applies fair value accounting for its financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The objective of a fair value measurement is to estimate the price to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. Assets and liabilities subject to fair value measurement disclosures are required to be classified according to a three-level fair value hierarchy with respect to the inputs used to determine fair value. The level in which an asset or liability is disclosed within the fair value hierarchy is based on the lowest level input that is significant to the related fair value measurement in its entirety. The levels of input are defined as follows: Level 1: Quoted prices unadjusted for identical assets or liabilities in an active market. Level 2: Quoted prices for similar assets or liabilities in an active market, quoted prices for identical similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data. Level 3: Unobservable inputs that reflect the entity's own assumptions which market participants would use in pricing the asset or liability.
Receivables	Receivables The Company records receivables at their face amounts less an allowance for doubtful accounts. Receivables consist of amounts billed and currently due from customers, amounts earned but unbilled (including contracts measured under the percentage-of-completion cost-to-cost method of accounting), amounts retained by the customer until the completion of a specified contract and claims. Unbilled recoverable amounts under contracts in progress generally become billable upon the passage of time, the achievement of project milestones, or upon acceptance by the customer. Allowances for uncollectible trade receivables are estimated based on a combination of write-off history, aging analysis, any known collectability issues, and certain forward-looking information.
Property and Equipment	Property and Equipment Property and equipment, which include assets under capital leases, are stated at cost less accumulated depreciation. Depreciation is computed predominantly on a straight-line basis over the estimated useful lives of the assets or the remaining lease term. The estimated useful lives of DXC's property and equipment are as follows: Buildings Up to 40 years Computers and related equipment 4 to 7 years Furniture and other equipment 3 to 15 years Leasehold improvements Shorter of lease term or useful life up to 20 years
Intangible Assets	Intangible Assets The Company's estimated useful lives for finite-lived intangibles are shown in the table below: Software 2 to 10 years Customer related intangibles Expected customer service life Acquired contract related intangibles Contract life and first contract renewal, where applicable Software is amortized using predominately the straight-line method (see Software Development Costs above). Acquired contract related and customer related intangible assets are amortized in proportion to the estimated undiscounted cash flows projected over the estimated life of the asset or on a straight-line basis if such cash flows cannot be reliably estimated.
Impairment of Long-Lived Assets and Finite-Lived Intangible Assets and Assets/Liabilities Held for Sale	Impairment of Long-Lived Assets and Finite-Lived Intangible Assets Long-lived assets such as property and equipment and finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable. Recoverability of long-lived assets or groups of assets is assessed based on a comparison of the carrying amount of such assets to the estimated future net cash flows. If estimated future net cash flows are less than the carrying amount of such assets, an expense is recorded in the amount required to reduce the carrying amount of such assets to fair value. Fair value is determined based on a discounted cash flow approach or, when available and appropriate, comparable market values. Long-lived assets to be disposed of are reported at the lower of their carrying amount or their fair value less costs to sell. Assets/Liabilities Held for Sale The Company classifies assets as held for sale in the period when the following conditions are met: (i) management, having the authority to approve the action, commits to a plan to sell the asset (disposal group); (ii) the asset (disposal group) is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets (disposal group); (iii) an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; (iv) the sale of the asset (disposal group) is probable, and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond our control extend the period of time required to sell the asset (disposal group) beyond one year; (v) the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (vi) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A long-lived asset (disposal group) that is classified as held for sale is initially measured at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset (disposal group) until the date of sale.
Income Taxes	Income Taxes The Company uses the liability method in accounting for income taxes. Deferred tax assets and liabilities are recorded for the expected future tax consequences of temporary differences between financial statement carrying amounts of assets and liabilities and their respective tax bases, using statutory tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the results of operations in the period that includes the related enactment date. A valuation allowance is established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances from period to period are included in the Company’s tax provision during the period in which the change occurred. In determining whether a valuation allowance is warranted, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, taxable income in prior carryback years, projected future taxable income, tax planning strategies and recent results of financial operations. The Company recognizes the tax benefit of uncertain tax positions when it is more likely than not that the tax position will be sustained upon examination. Uncertain tax positions are measured based on the probabilities that the uncertain tax position will be realized upon final settlement. All tax-related cash flows resulting from excess tax benefits related to the settlement of share-based awards are classified as cash flows from operating activities and cash paid by directly withholding shares for tax withholding purposes is classified as a financing activity in the statements of cash flows.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers investments with an original maturity of three months or less to be cash equivalents. The Company’s cash equivalents consist of time deposits, money market funds and money market deposit accounts with a number of institutions that have high credit ratings.
Foreign Currency	Foreign Currency The local currency of the Company's foreign affiliates is generally their functional currency. Accordingly, the assets and liabilities of the foreign affiliates are translated from their respective functional currency to U.S. dollars using fiscal year-end exchange rates, income and expense accounts are translated at the average rates in effect during the fiscal year and equity accounts are translated at historical rates. The resulting translation adjustment is reported in the statements of comprehensive income and recorded as part of accumulated other comprehensive (loss) income.
Derivative Instruments	Derivative Instruments The Company designates certain derivative instruments as hedges for purposes of hedge accounting, as defined under ASC 815 “Derivatives and Hedging.” For such derivative instruments, the Company documents its risk management objectives and strategy for undertaking hedging transactions, as well as all relationships between hedging and hedged risks. The Company's derivative instruments designated for hedge accounting include interest rate swaps and foreign currency forward and option contracts. Changes in the fair value measurements of these derivative instruments are reflected as adjustments to other comprehensive (loss) income and subsequently reclassified into earnings in the period during which the hedged transactions occurred. Any ineffectiveness or excluded portion of a designated hedge is recognized in earnings. The Company also has entered into certain net investment hedges. Changes in the fair value of net investment hedges are recorded in the currency translation adjustment section of other comprehensive (loss) income and subsequently reclassified into earnings in the period the hedged item affects earnings. The Company excludes forward points from the effectiveness assessment of its net investment hedges. Changes in fair value of the excluded component are recognized in earnings. The derivative instruments not designated as hedges for purposes of hedge accounting include total return swaps and certain short-term foreign currency forward contracts. These instruments are recorded at their respective fair values and the change in their value is reported in current period earnings. The Company does not use derivative instruments for trading or speculative purpose. The Company reports the effective portion of its cash flow hedges in the same financial statement line item as changes in the fair value of the hedged item. All cash flows associated with the Company's derivative instruments are classified as operating activities in the statements of cash flows.
