Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Business DXC Technology Company (“DXC,” the “Company,” “we,” “us,” or “our”) helps global companies run their mission critical systems and operations while modernizing IT, optimizing data architectures, and ensuring security and scalability across public, private and hybrid clouds. The world’s largest companies and public sector organizations trust DXC to deploy services to drive new levels of performance, competitiveness and customer experience across their IT estates. Basis of Presentation In order to make this report easier to read, DXC refers throughout to (i) the interim unaudited Condensed Consolidated Financial Statements as the “financial statements,” (ii) the Condensed Consolidated Statements of Operations as the “statements of operations,” (iii) the Condensed Consolidated Statements of Comprehensive Income (Loss) as the “statements of comprehensive income (loss),” (iv) the Condensed Consolidated Balance Sheets as the “balance sheets,” and (v) the Condensed Consolidated Statements of Cash Flows as the “statements of cash flows.” In addition, references are made throughout to the numbered Notes to the Condensed Consolidated Financial Statements (“Notes”) in this Quarterly Report on Form 10-Q. The accompanying 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 income (loss) attributable to non-controlling interests are presented separately in the statements of comprehensive income (loss). 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. The financial statements of the Company have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for quarterly reports and accounting principles generally accepted in the United States (“GAAP”). Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules. These financial statements should therefore be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2023 (“fiscal 2023”). 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 and liabilities as well as the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. 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 are 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. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full fiscal year. Recent Accounting Pronouncements Recently issued Accounting Standards Updates (“ASUs”) effective after September 30, 2023 are not expected to have a material effect on DXC’s condensed consolidated financial statements.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share (“EPS”) is computed using the weighted average number of shares of common stock outstanding during the period. Diluted EPS reflects the incremental shares issuable upon the assumed exercise of stock options and equity awards. The following table reflects the calculation of basic and diluted EPS: Three Months Ended Six Months Ended (in millions, except per-share amounts) September 30, 2023 September 30, 2022 September 30, 2023 September 30, 2022 Net income attributable to DXC common stockholders: $ 99 $ 27 $ 135 $ 129 Common share information: Weighted average common shares outstanding for basic EPS 201.72 229.96 205.90 231.21 Dilutive effect of stock options and equity awards 1.34 3.21 3.00 3.72 Weighted average common shares outstanding for diluted EPS 203.06 233.17 208.90 234.93 Earnings per share: Basic $ 0.49 $ 0.12 $ 0.66 $ 0.56 Diluted $ 0.49 $ 0.12 $ 0.65 $ 0.55 Certain share-based equity awards were excluded from the computation of dilutive EPS because inclusion of these awards would have had an anti-dilutive effect. The number of awards excluded were as follows: Three Months Ended Six Months Ended September 30, 2023 September 30, 2022 September 30, 2023 September 30, 2022 Stock Options 960,455 475,559 924,990 478,128 Restricted Stock Units 1,556,542 2,724,766 1,480,781 2,065,992 Performance Stock Units 1,700,588 1,079,287 35,604 721,803

The Receivables Facility was amended on July 28, 2023 extending the termination date to July 26, 2024. As of September 30, 2023, the total availability under the Receivables Facility was $384 million and the amount sold to the Purchasers was $378 million, which was derecognized from the Company’s balance sheet. As of September 30, 2023, the Company recorded an asset of $6 million within accounts receivable because the amount of cash proceeds received by the Company under the Receivables Facility was less than the total availability. The fair value of the sold receivables approximated book value due to the short-term nature, and as a result, no gain or loss on sale of receivables was recorded.

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 purposes. 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 Euro and Indian Rupee-denominated obligations and forecasted transactions. The notional amounts of foreign currency forward contracts designated as cash flow hedges as of September 30, 2023 and March 31, 2023 were $889 million and $842 million, respectively. As of September 30, 2023, the related forecasted transactions extend through September 2025. During the three and six months ended September 30, 2023 and September 30, 2022, respectively, the Company had no cash flow hedges for which it was probable that the hedged transaction would not occur. See Note 15 - “Stockholders’ Equity” for changes in accumulated other comprehensive loss, net of taxes, related to the Company’s derivatives designated for hedge accounting. As of September 30, 2023, $1 million of the existing amount of gain related to the cash flow hedge reported in accumulated other comprehensive loss is expected to be reclassified into earnings within the next 12 months. 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 short-term foreign currency forward contracts to hedge certain foreign currency denominated assets and liabilities, including intercompany accounts and forecasted transactions. The net notional amounts of the foreign currency forward contracts outstanding as of September 30, 2023 and March 31, 2023 were $2.4 billion and $2.5 billion, respectively. The following table presents the foreign currency (gain) loss to Other income, net: For the Three Months Ended For the Six Months Ended (in millions) September 30, 2023 September 30, 2022 September 30, 2023 September 30, 2022 Foreign currency remeasurement (1) $ 25 $ 40 $ 21 $ 76 Undesignated foreign currency forward contracts (2) (26) (41) (30) (79) Total - Foreign currency gain $ (1) $ (1) $ (9) $ (3) (1) Movements from exchange rates on the Company’s foreign currency-denominated assets and liabilities. (2) Movements from hedges used to manage the Company’s foreign currency remeasurement exposure, and the associated costs of the hedging program. 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 September 30, 2023 March 31, 2023 Derivatives designated for hedge accounting: Foreign currency forward contracts Other current assets $ 9 $ 6 Accrued expenses and other current liabilities $ 6 $ 13 Derivatives not designated for hedge accounting: Foreign currency forward contracts Other current assets $ 35 $ 15 Accrued expenses and other current liabilities $ 13 $ 16 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 September 30, 2023, there were six counterparties with concentration of credit risk, and based on gross fair value, the maximum amount of loss that the Company could incur is $21 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 income (loss) when such net investments are sold or substantially liquidated.

Goodwill Impairment Analyses 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 concluded that, as a result of its qualitative assessment performed on July 1, 2023, it remained more likely than not that the fair value of the GBS reporting unit exceeds its carrying amount. As of September 30, 2023, 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 September 30, 2023.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate (“ETR”) was 22.7% and 48.1% for the three months ended September 30, 2023 and September 30, 2022, respectively, and 31.6% and 25.6% for the six months ended September 30, 2023 and September 30, 2022, respectively. For the three and six months ended September 30, 2023, the primary drivers of the ETR were the global mix of income, U.S. tax on foreign income, a decrease in valuation allowances on deferred tax assets, and the foreign tax credit. For the three months ended September 30, 2022, the primary drivers of the ETR were the global mix of income, U.S. tax on foreign income, and the tax impact of business divestitures. For the six months ended September 30, 2022, the primary drivers of the ETR were the global mix of income, tax impact of business divestitures, U.S. tax on foreign income, and a decrease in unrecognized tax benefits due to income tax audit settlements and statute of limitation expirations. 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 $471 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. In connection with the merger of Computer Sciences Corporation (“CSC”) and the Enterprise Services business of Hewlett Packard Enterprise Company (the “HPES Merger”), the Company entered into a tax matters agreement with Hewlett Packard Enterprise Company (“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 $16 million tax indemnification receivable related to uncertain tax positions, a $52 million tax indemnification receivable related to other tax payables, and a $91 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 $17 million tax indemnification receivable from Perspecta related to other tax receivables and a $6 million tax indemnification payable to Perspecta related to income tax and other tax payables. In connection with the sale of its healthcare provider software business (“HPS”), 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. 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 $491 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. During the first six months of fiscal 2024, some of these cases were dismissed, but the dismissals were procedural in nature only and do not impact the Company’s potential liability for the aforementioned fiscal years. 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, 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. For the three months ended September 30, 2023, the Company’s liability for uncertain tax positions increased by $2 million (excluding interest and penalties and related tax attributes) primarily due to the benefit of U.S. research and development income tax credits. 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 $14 million.

Share-Based Payment Arrangement [Abstract]
Stock Incentive Plans	Stock Incentive Plans Restricted Stock Units and Performance-Based Restricted Stock Units 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. The Company also grants performance-based restricted stock units (“PSUs”), which generally vest over a three-year period. The number of PSUs that ultimately vest is dependent upon the Company’s achievement of certain specified market- and performance-based criteria over the three-year vesting period. The fair value of RSUs and PSUs is based on the Company’s common stock closing price on the grant date. For PSUs with a market-based condition, DXC uses a Monte Carlo simulation model to value the grants.

Reconciliation of Reportable Segment Profit to Consolidated Total 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 other post-retirement benefit (“OPEB”) actuarial and settlement gains and losses, restructuring costs, transaction, separation, and integration-related costs and amortization of acquired intangible assets.

Commitments and Contingencies	Commitments and Contingencies Commitments Minimum purchase commitments as of September 30, 2023 were as follows: Fiscal year Minimum Purchase Commitment (in millions) Remainder of 2024 $ 349 2025 616 2026 536 2027 119 2028 75 Thereafter 23 Total $ 1,718 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. In September 2023, the parties entered into a settlement agreement to resolve the matter and submitted it to the District Court for approval. In October 2023, the District Court entered an order preliminarily approving the proposed settlement. 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 former shareholders of Computer Sciences Corporation (“CSC”) who exchanged their CSC shares for 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. A hearing on Plaintiffs’ motion for class certification is scheduled for January 2024. The case is otherwise 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 14 – “Income Taxes” for further information. 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.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In order to make this report easier to read, DXC refers throughout to (i) the interim unaudited Condensed Consolidated Financial Statements as the “financial statements,” (ii) the Condensed Consolidated Statements of Operations as the “statements of operations,” (iii) the Condensed Consolidated Statements of Comprehensive Income (Loss) as the “statements of comprehensive income (loss),” (iv) the Condensed Consolidated Balance Sheets as the “balance sheets,” and (v) the Condensed Consolidated Statements of Cash Flows as the “statements of cash flows.” In addition, references are made throughout to the numbered Notes to the Condensed Consolidated Financial Statements (“Notes”) in this Quarterly Report on Form 10-Q. The accompanying 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 income (loss) attributable to non-controlling interests are presented separately in the statements of comprehensive income (loss). 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. The financial statements of the Company have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for quarterly reports and accounting principles generally accepted in the United States (“GAAP”). Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules. These financial statements should therefore be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2023 (“fiscal 2023”).
Use of Estimates	Use of EstimatesThe 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 and liabilities as well as the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. 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 are 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. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full fiscal year.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently issued Accounting Standards Updates (“ASUs”) effective after September 30, 2023 are not expected to have a material effect on DXC’s condensed consolidated financial statements.
