Overview and Basis of Presentat

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Presentation	Overview and Basis of Presentation Background Perspecta is a leading provider of end-to-end enterprise information technology (“IT”), mission, and operations-related services across the United States (“U.S.”) federal government to the Department of Defense (“DoD”), the intelligence community, and homeland security, civilian and health care agencies, as well as to certain state and local government agencies through two reportable segments: (1) Defense and Intelligence, which provides services to the DoD, intelligence community, branches of the U.S. Armed Forces, and other DoD agencies, and (2) Civilian and Health Care, which provides services to the Departments of Homeland Security, Justice, and Health and Human Services, as well as other federal civilian and state and local government agencies. The accompanying unaudited condensed consolidated combined financial statements and notes present the combined results of operations, financial position, and cash flows of USPS for the periods prior to the completion of the Spin-Off and the combination with Vencore HC and KGS HC. Accordingly, the term “Parent” refers to DXC for periods from April 1, 2018 to May 31, 2018. As used in these notes, “the Company,” “we,” “us,” and “our” refer to the combined businesses of USPS for the period from April 1, 2018 through May 31, 2018, and to Perspecta and its consolidated subsidiaries for the periods from June 1, 2018 through September 30, 2018 and April 1, 2019 through September 30, 2019 . Basis of Presentation The accompanying unaudited condensed consolidated combined financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). As discussed above, the Spin-Off and the Mergers were not consummated until May 31, 2018. In the period prior to consummation of the Spin-Off and Mergers, these financial statements include the combined financial statements of USPS, derived from the consolidated combined financial statements and accounting records of Parent as if USPS were operated on a stand-alone basis during the periods presented and were prepared in accordance with GAAP and, subsequent to the Spin-Off and Mergers, these financial statements represent the consolidated financial statements of Perspecta and its subsidiaries. Accordingly, the accompanying unaudited financial statements are presented as described below. The period prior to the Spin-Off and Mergers includes the combined financial results and cash flows of USPS for the period from April 1, 2018 to May 31, 2018. The periods subsequent to the Spin-Off and Mergers include: • the consolidated financial statements of Perspecta for the period from June 1, 2018 to September 30, 2018 ; • the consolidated financial statements of Perspecta for the period from April 1, 2019 to September 30, 2019 ; and • the consolidated financial position of Perspecta as of September 30, 2019 and March 31, 2019 . After the Spin-Off, DXC does not have any beneficial ownership of Perspecta or USPS. The chairman of the board of directors and former chief executive officer of DXC also serves as chairman of the board of directors of Perspecta (the “Board of Directors”). Consequently, transactions between DXC and Perspecta are reflected as related party transactions pursuant to the disclosure requirements of Accounting Standards Codification (“ASC”) Topic 850, Related Party Disclosures. For additional information about the allocation of expenses from DXC prior to the Spin-Off and certain continuing responsibilities between the Company and DXC, see Note 13 – “ Related Party Transactions .” Principles of Consolidation and Combination The unaudited condensed consolidated combined financial statements as of and for the three and six months ended September 30, 2019 and 2018 reflect the financial position and results of operations of the Company and its consolidated subsidiaries. The combined financial statements as of and for periods prior to the consummation of the Spin-Off, reflect the financial position and results of operations of USPS as described above. The financial statements for the periods prior to the Spin-Off are prepared on a carved-out and combined basis from the financial statements of DXC. The unaudited condensed consolidated combined statements of operations of USPS reflect allocations of general corporate expenses from DXC, including, but not limited to, executive management, finance, legal, IT, employee benefits administration, treasury, risk management, procurement and other shared services. These allocations were made on a direct usage basis when identifiable, with the remainder allocated on the basis of revenue, expenses, headcount or other relevant measures. Management of Perspecta considers these allocations to be a reasonable reflection of the utilization of services by, or the benefits provided to, USPS. The allocations may not, however, reflect the expense USPS would have incurred as a stand-alone company for the periods presented. Actual costs that may have been incurred if USPS had been a stand-alone company would depend on a number of factors, including the chosen organizational structure, what functions were outsourced or performed by employees and strategic decisions made in areas such as IT and infrastructure. Prior to consummation of the Spin-Off, USPS generated cash in the normal course of its business. Parent swept the cash USPS generated via transfers to Parent’s cash management system. Parent’s receivables sales facility and long-term debt, other than capital lease obligations, have not been attributed to USPS for the periods prior to consummation of the Spin-Off because Parent’s borrowings were not the legal obligation of USPS. The unaudited condensed consolidated combined financial statements for prior periods, included herein, may not be indicative of the financial position, results of operations and cash flows of the Company in the future or if USPS had been operated as a consolidated group during all periods presented. In the opinion of management of the Company, the accompanying interim unaudited condensed consolidated combined financial statements contain all adjustments, including normal recurring adjustments, necessary to present fairly our results of operations and cash flows. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Amounts subject to significant judgment and/or estimates include, but are not limited to, determining the fair value of assets acquired and liabilities assumed, the evaluation of impairment of goodwill and other long-lived intangible assets, costs to complete fixed-price contracts, fair value, certain deferred costs, valuation allowances on deferred tax assets, loss accruals for litigation, and inputs used for computing stock-based compensation and pension related liabilities. These estimates are based on management’s best knowledge of historical experience, current events, and various other assumptions that management considers reasonable under the circumstances. Reclassifications Certain prior period balances in the accompanying financial statements have been reclassified to conform to the current period presentation. These reclassifications had no impact on total assets, total liabilities, total equity, income before taxes or net income.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) Section A—Leases (“ASU 2016-02”). ASU 2016-02, along with related amendments (“ASC 842”), requires lessees to record, at lease inception, a lease liability for the obligation to make lease payments and a right-of-use (“ROU”) asset for the right to use the underlying asset for the lease term on their balance sheets. Management developed a detailed implementation plan, which included, among other things, implementation of a new lease accounting system, an update to our policies, development of disclosures, evaluation of our controls, and application of the guidance across our contract population. The Company adopted the standard on April 1, 2019 using the optional transition method. Under this method, the Company applied the standard through a cumulative-effect adjustment in the period of adoption. In addition, the Company has elected to adopt additional practical expedients, including combining lease and non-lease components, applying the discount rate to a portfolio of leases with similar lease durations based on the original lease duration, and maintaining prior lease classification upon adoption. The adoption of ASC 842 resulted in the recognition of $114 million and $130 million of ROU assets and lease liabilities, respectively, on our balance sheet related to operating leases. The adoption did not have a material impact on our statements of operations, changes in stockholders’ equity or cash flows. See Note 10 – “ Leases ” for further details. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The guidance, along with related amendments, changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company will adopt ASU 2016-13 on April 1, 2020 and is currently assessing the impact that this guidance will have on its trade receivables and financial arrangements when adopted; however, given the concentration of receivables with the U.S. government, the adoption is not expected to have a material effect on Perspecta’s financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350- 40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). ASU 2018-15 provides guidance for determining when a cloud computing arrangement includes a software license and makes changes to the requirements for capitalizing implementation costs incurred in a hosting arrangement that is as a service contract. The amendment is effective for public entities for fiscal years beginning after December 15, 2019, and early adoption is permitted. The update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company will adopt ASU 2018-15 on April 1, 2020 and is currently evaluating the method and impact of adoption on its financial statements and related disclosures. Other recently issued ASUs effective after September 30, 2019 are not expected to have a material effect on Perspecta’s financial statements.

Business Combinations [Abstract]
Acquisitions	Acquisitions Knight Point Systems, LLC On July 31, 2019, Perspecta acquired all of the equity interests of Knight Point Systems, LLC (“Knight Point”) for $250 million plus customary purchase price adjustments, totaling an estimated purchase price of $265 million . Knight Point delivers end-to-end managed services and solutions focused on modernizing IT systems, protecting critical networks and driving digital transformation to improve customer transparency and operational efficiency. Knight Point leverages a portfolio of intellectual property to solve complex customer challenges in cloud, cybersecurity and agile development and operations (“ DevOps ”) environments. The Company recognized preliminary fair values of the assets acquired and liabilities assumed and allocated $116 million to goodwill and $125 million to intangible assets. The goodwill is largely attributable to the assembled workforce of Knight Point and expected synergies between the Company and Knight Point. The Company’s preliminary allocation of goodwill to Perspecta’s reportable segments was as follows: $22 million allocated to Defense and Intelligence and $94 million allocated to Civilian and Health Care. The intangible assets consist primarily of program assets of $102 million , developed technology of $18 million and backlog of $5 million . The estimated fair value attributed to intangible assets is being amortized on an accelerated basis over a range of 10 to 12 years for program assets, seven years for developed technology and one year for backlog. The fair value attributed to the intangible assets acquired was based on preliminary estimates, assumptions, and other information compiled by management, including independent valuations that utilized established valuation techniques. All of the value attributed to goodwill and intangible assets is deductible for income tax purposes. The fair values of assets acquired and liabilities assumed are preliminary and based on a valuation using estimates and assumptions that are subject to change, which could result in material changes to the purchase price allocation. The final purchase price allocation is expected to be completed by the first quarter of fiscal year 2021, pending a working capital adjustment and final appraisals and other analysis of the fair values and tax bases of acquired assets and liabilities. The results of operations of Knight Point have been included in the statement of operations beginning August 1, 2019. Pro forma results of operations for this acquisition have not been presented as it is not material to the consolidated results of operations. The acquisition was considered an asset purchase for tax purposes. Unaudited Pro Forma Financial Information for the Spin-Off and the Mergers The following unaudited pro forma financial information presents results as if the Spin-Off and the Mergers and the related financing had occurred on April 1, 2017. The historical consolidated financial information of Perspecta has been adjusted in the pro forma information to give effect to the events that are (1) directly attributable to the transactions, (2) factually supportable and (3) expected to have a continuing impact on the combined results. The effects of the Spin-Off are primarily attributable to interest expense associated with the incurrence of debt in connection with the Spin-Off. The effects of the Mergers primarily relate to amortization of acquired intangible assets. The consolidated financial information of Perspecta includes merger and integration-related costs that are not expected to recur and impact the combined results over the long term.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company estimates the fair value of its long-term debt primarily using an expected present value technique, which is based on observable market inputs, using interest rates currently available to the Company for instruments with similar terms and remaining maturities. The estimated fair value of the Company’s long-term debt, excluding finance leases and unamortized debt issuance costs, was $2.54 billion and $2.35 billion as of September 30, 2019 and March 31, 2019 , respectively, as compared with the gross carrying value of $2.54 billion and $2.40 billion , respectively. If measured at fair value, long-term debt, excluding finance lease liabilities, would be classified in Level 2 of the fair value hierarchy. Non-financial assets such as goodwill, tangible assets, intangible assets and other contract related long-lived assets are reduced to fair value in the period an impairment charge is recognized. The fair value measurements, in such instances, would be classified in Level 3. There were no significant impairments recorded during the three and six months ended September 30, 2019 or 2018 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In the normal course of business, the Company is exposed to interest rate fluctuations. As part of its risk management strategy, the Company uses derivative instruments, primarily interest rate swaps, to hedge certain interest rate exposures. The Company’s objective is to add stability to interest expense and to manage its exposure to movements in market interest rates. The Company does not use derivative instruments for trading or any speculative purpose. As of September 30, 2019 , the Company had interest rate swap agreements with a total notional amount of $1.60 billion . The Company initially accounted for all changes in fair value of its interest rate swaps on the statements of operations until designation as a cash flow hedge of interest rate risk on June 22, 2018. As a result, the Company recorded a gain of $5 million included in interest expense, net on the statement of operations for the six months ended September 30, 2018 . Following the June 22, 2018 cash flow hedge designation, all changes in the hedging instruments’ fair value are recorded in accumulated other comprehensive loss (“AOCL”) and subsequently reclassified into earnings in the period during which the hedged transactions are recognized in earnings. The pre-tax impact of loss on derivatives designated for hedge accounting recognized in other comprehensive loss was $4 million ( $3 million , net of tax) and $28 million ( $21 million , net of tax) for the three and six months ended September 30, 2019 , respectively. The pre-tax impact of income on derivatives designated for hedge accounting recognized in other comprehensive income was $8 million ( $6 million , net of tax) and $7 million ( $5 million , net of tax) for the three and six months ended September 30, 2018 , respectively. We reclassified $2 million and $3 million from AOCL into earnings during the three and six months ended September 30, 2019 , respectively. As of September 30, 2019 , we expect amounts of approximately $18 million pertaining to cash flow hedges to be reclassified from AOCL into earnings over the next 12 months. All derivatives are recorded at fair value. The Company’s accounting treatment for these derivative instruments is based on its hedge designation. As of September 30, 2019 , the gross fair value of our derivative liabilities in interest rate swaps designated for hedge accounting is $55 million , of which $16 million is presented as other current liabilities and $39 million is presented as other liabilities on the balance sheet . As of March 31, 2019 , the gross fair value of our derivative liabilities in interest rate swaps designated for hedge accounting was $26 million , of which $4 million is presented in other current liabilities and $22 million is presented in other liabilities on the balance sheet . The fair value of interest rate swaps is estimated based on valuation models that use interest rate yield curves as Level 2 inputs.

Leases [Abstract]
Leases	Leases As described in Note 2 – “ Recent Accounting Pronouncements ,” effective April 1, 2019, we adopted ASC 842 using the optional transition method. In accordance with the optional transition method, we did not recast the prior period financial statements, and all prior period amounts and disclosures are presented under ASC 840. The Company leases certain real and personal property under non-cancelable operating leases. Lease assets under finance leases is comprised primarily of computers and related equipment. Finance lease obligations primarily consist of contractual arrangements with HPE Financial Services. Under ASC 842, an arrangement is determined to be a lease at inception if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. At inception, we determine whether the contract is or contains a lease and, if so, whether the lease should be classified as an operating or a finance lease. The Company recognizes a ROU asset and a lease liability based on the present value of the future minimum lease payments over the lease term at the commencement date, adjusted for any lease incentives, initial direct costs, and potential impairment. At the commencement date, a single discount rate is applied to a group of leases with the same durations. The rate is updated quarterly for new leases that commence during the period, unless a triggering event occurs requiring more frequent reassessment. We define the initial lease term to include renewal options determined to be reasonably certain. Lease assets are evaluated for impairment in a manner consistent with the treatment of other long-lived assets. Certain leases require us to pay property taxes, insurance and routine maintenance, which are included in variable lease expense. At September 30, 2019 , the Company did not have any lease agreements with residual value guarantees or material restrictions or covenants.

Stock-based Compensation The Company recognized $10 million and $15 million in stock-based compensation expense during the three and six months ended September 30, 2019 , respectively, compared to $1 million and $3 million for the three and six months ended September 30, 2018 , respectively. During the six months ended September 30, 2019 , the Company granted approximately 558 thousand time-based restricted stock units (“RSUs”) and approximately 923 thousand performance-based restricted stock units (“PSUs”). The RSUs and PSUs are valued using the closing price on the trading day of the grant. The weighted average grant date fair value of the RSUs and PSUs granted during the six months ended September 30, 2019 was $23.17 and $23.01 , respectively.

Segment Reporting [Abstract]
Segment Information	Segment Information We operate based on two reportable segments: (1) Defense and Intelligence, and (2) Civilian and Health Care. Our reportable segments and their respective operations are defined as follows: Defense and Intelligence Through its Defense and Intelligence business, Perspecta provides cybersecurity, data analytics, digital transformation, information technology modernization, and agile software development, as well as technology to support intelligence, surveillance, and reconnaissance services to the DoD, intelligence community, branches of the U.S. Armed Forces, and other DoD agencies. Key competitive differentiators for the Defense and Intelligence segment include global scale, solution objectivity, depth of industry expertise, strong partnerships, vendor and product independence and end-to-end solutions and capabilities. Evolving business demands such as globalization, fast-developing economies, government regulation and growing concerns around risk, security, and compliance drive demand for these offerings. Civilian and Health Care Through its Civilian and Health Care business, Perspecta provides enterprise IT transformation and modernization, application development and modernization, enterprise security, risk decision support, operations and sustainment, systems engineering, applied research, cyber services, and cloud transformation to the Departments of Homeland Security, Justice, and Health and Human Services, as well as other federal civilian and state and local government agencies. Segment Measures The following table summarizes operating results regularly provided to the chief operating decision maker by reportable segment: Three Months Ended Six Months Ended (in millions) September 30, 2019 September 30, 2018 September 30, 2019 September 30, 2018 Revenue Defense and Intelligence $ 777 $ 702 $ 1,529 $ 1,139 Civilian and Health Care 395 366 750 722 Total revenue $ 1,172 $ 1,068 $ 2,279 $ 1,861 Segment profit (1) Defense and Intelligence $ 113 $ 87 $ 231 $ 123 Civilian and Health Care 40 41 73 102 Total segment profit $ 153 $ 128 $ 304 $ 225 Depreciation and amortization Defense and Intelligence $ 24 $ 18 $ 49 $ 37 Civilian and Health Care 16 20 44 40 Amortization of acquired intangible assets 50 36 98 61 Total depreciation and amortization $ 90 $ 74 $ 191 $ 138 (1) The segment profit for the three and six months ended September 30, 2018 was revised to reflect the change to exclude the amortization expense on intangible assets acquired in business combinations as disclosed in Note 19 – “Segment Information” to the financial statements of our Annual Report on Form 10‑K for the year ended March 31, 2019 . Reconciliation of Reportable Segment Profit to the Statements of Operations The Company’s management uses segment profit as the measure for assessing performance of its segments. Segment profit is defined as segment revenue less segment cost of services, selling, general and administrative and depreciation and amortization, excluding certain operating expenses managed at the corporate level. These unallocated costs include certain corporate function costs, stock-based compensation expense, amortization of acquired intangible assets, certain nonrecoverable restructuring costs, separation, transaction and integration-related costs and net periodic benefit cost.

As a result, assets are not tracked by segment and therefore, total assets by segment is not disclosed.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is a party to or has responsibility under various lawsuits, claims, investigations and proceedings involving disputes or potential disputes related to commercial, employment and regulatory matters that arise in the ordinary course of business. The Separation and Distribution Agreement (the “SDA”) between Perspecta and DXC includes provisions that allocate liability and financial responsibility for litigation involving DXC and the Company and that provide for cross-indemnification of the parties for liabilities a party may incur that are allocated to the other party under the SDA. In addition, under the SDA, DXC and the Company have agreed to cooperate with each other in managing litigation that relates to both parties’ businesses. The SDA also contains provisions that allocate liability and financial responsibility for such litigation. The Company records a liability when it believes that it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated. Significant judgment is required to determine both the probability of having incurred a liability and the estimated amount of the liability. The Company reviews these matters at least quarterly and adjusts these liabilities to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other updated information and events pertaining to a particular matter. Litigation is inherently unpredictable. However, the Company believes it has valid defenses with respect to legal matters pending against it. Nevertheless, cash flows or results of operations could be materially affected in any particular period by the resolution of one or more of these contingencies. The Company believes it has recorded adequate provisions for any such matters and, as of September 30, 2019 , it was not reasonably possible that a material loss had been incurred in connection with such matters in excess of the amounts recognized in its financial statements. Litigation, Proceedings and Investigations Forsyth, et al. v. HP Inc. and Hewlett Packard Enterprise: This purported class and collective action was filed on August 18, 2016 in the U.S. District Court for the Northern District of California, against HP Inc. and Hewlett Packard Enterprise Company (“HPE”) alleging violations of the Federal Age Discrimination in Employment Act (“ADEA”), the California Fair Employment and Housing Act, California public policy and the California Business and Professions Code. Plaintiffs filed an amended complaint on December 19, 2016. Plaintiffs seek to certify a nationwide class action under the ADEA comprised of all U.S. residents employed by defendants who had their employment terminated pursuant to a work force reduction (“WFR”) plan on or after December 9, 2014 (deferral states) and April 8, 2015 (non-deferral states), and who were 40 years of age or older at the time of termination. Plaintiffs also seek to represent a Rule 23 class under California law comprised of all persons 40 years or older employed by defendants in the state of California and terminated pursuant to a WFR plan on or after August 18, 2012. The case has remained stayed while the parties have engaged in mediation with opt-in plaintiffs who are subject to mandatory, individual arbitration agreements. Two mediation sessions have taken place. In October 2018, a settlement was reached with 16 named and opt-in plaintiffs; that settlement has been completed. On June 26-27, 2019, a second mediation was held, involving 145 opt-in plaintiffs. Discussions continue. Former business units of HPE now owned by the Company will be liable in this matter for any recovery by plaintiffs previously associated with the USPS business of HPE. In addition to the matter 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 counter parties and other parties, 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. The Company 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. Guarantees The Company uses stand-by letters of credit, in lieu of cash, to support various risk management insurance policies, which are cash collateralized. 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 Company’s stand-by letters of credit outstanding were less than $1 million as of September 30, 2019 . As of September 30, 2019 , the Company had $34 million in outstanding surety bonds, of which less than $1 million expire in each of fiscal years 2020 and 2021, and $33 million expire in fiscal year 2022.

Subsequent Events	Subsequent Events On October 4, 2019, we completed a sale and leaseback transaction of our Herndon, Virginia facility. The land and buildings sold had a carrying value of $23 million , which was included in assets held for sale on our balance sheets as of September 30, 2019 and March 31, 2019. We will recognize a gain on sale of assets of approximately $30 million during the third quarter of fiscal year 2020. The leaseback period will facilitate the Company’s exit from the facility. Effective October 31, 2019, the Company completed the fourth amendment and joinder to the MARPA Facility to extend the maturity of the facility through October 30, 2020 and to amend certain other terms.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated combined financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). As discussed above, the Spin-Off and the Mergers were not consummated until May 31, 2018. In the period prior to consummation of the Spin-Off and Mergers, these financial statements include the combined financial statements of USPS, derived from the consolidated combined financial statements and accounting records of Parent as if USPS were operated on a stand-alone basis during the periods presented and were prepared in accordance with GAAP and, subsequent to the Spin-Off and Mergers, these financial statements represent the consolidated financial statements of Perspecta and its subsidiaries. Accordingly, the accompanying unaudited financial statements are presented as described below. The period prior to the Spin-Off and Mergers includes the combined financial results and cash flows of USPS for the period from April 1, 2018 to May 31, 2018. The periods subsequent to the Spin-Off and Mergers include: • the consolidated financial statements of Perspecta for the period from June 1, 2018 to September 30, 2018 ; • the consolidated financial statements of Perspecta for the period from April 1, 2019 to September 30, 2019 ; and • the consolidated financial position of Perspecta as of September 30, 2019 and March 31, 2019 . After the Spin-Off, DXC does not have any beneficial ownership of Perspecta or USPS. The chairman of the board of directors and former chief executive officer of DXC also serves as chairman of the board of directors of Perspecta (the “Board of Directors”). Consequently, transactions between DXC and Perspecta are reflected as related party transactions pursuant to the disclosure requirements of Accounting Standards Codification (“ASC”) Topic 850, Related Party Disclosures. For additional information about the allocation of expenses from DXC prior to the Spin-Off and certain continuing responsibilities between the Company and DXC, see Note 13 – “ Related Party Transactions .” Principles of Consolidation and Combination The unaudited condensed consolidated combined financial statements as of and for the three and six months ended September 30, 2019 and 2018 reflect the financial position and results of operations of the Company and its consolidated subsidiaries. The combined financial statements as of and for periods prior to the consummation of the Spin-Off, reflect the financial position and results of operations of USPS as described above. The financial statements for the periods prior to the Spin-Off are prepared on a carved-out and combined basis from the financial statements of DXC. The unaudited condensed consolidated combined statements of operations of USPS reflect allocations of general corporate expenses from DXC, including, but not limited to, executive management, finance, legal, IT, employee benefits administration, treasury, risk management, procurement and other shared services. These allocations were made on a direct usage basis when identifiable, with the remainder allocated on the basis of revenue, expenses, headcount or other relevant measures. Management of Perspecta considers these allocations to be a reasonable reflection of the utilization of services by, or the benefits provided to, USPS. The allocations may not, however, reflect the expense USPS would have incurred as a stand-alone company for the periods presented. Actual costs that may have been incurred if USPS had been a stand-alone company would depend on a number of factors, including the chosen organizational structure, what functions were outsourced or performed by employees and strategic decisions made in areas such as IT and infrastructure. Prior to consummation of the Spin-Off, USPS generated cash in the normal course of its business. Parent swept the cash USPS generated via transfers to Parent’s cash management system. Parent’s receivables sales facility and long-term debt, other than capital lease obligations, have not been attributed to USPS for the periods prior to consummation of the Spin-Off because Parent’s borrowings were not the legal obligation of USPS. The unaudited condensed consolidated combined financial statements for prior periods, included herein, may not be indicative of the financial position, results of operations and cash flows of the Company in the future or if USPS had been operated as a consolidated group during all periods presented. In the opinion of management of the Company, the accompanying interim unaudited condensed consolidated combined financial statements contain all adjustments, including normal recurring adjustments, necessary to present fairly our results of operations and cash flows.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) Section A—Leases (“ASU 2016-02”). ASU 2016-02, along with related amendments (“ASC 842”), requires lessees to record, at lease inception, a lease liability for the obligation to make lease payments and a right-of-use (“ROU”) asset for the right to use the underlying asset for the lease term on their balance sheets. Management developed a detailed implementation plan, which included, among other things, implementation of a new lease accounting system, an update to our policies, development of disclosures, evaluation of our controls, and application of the guidance across our contract population. The Company adopted the standard on April 1, 2019 using the optional transition method. Under this method, the Company applied the standard through a cumulative-effect adjustment in the period of adoption. In addition, the Company has elected to adopt additional practical expedients, including combining lease and non-lease components, applying the discount rate to a portfolio of leases with similar lease durations based on the original lease duration, and maintaining prior lease classification upon adoption. The adoption of ASC 842 resulted in the recognition of $114 million and $130 million of ROU assets and lease liabilities, respectively, on our balance sheet related to operating leases. The adoption did not have a material impact on our statements of operations, changes in stockholders’ equity or cash flows. See Note 10 – “ Leases ” for further details. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The guidance, along with related amendments, changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company will adopt ASU 2016-13 on April 1, 2020 and is currently assessing the impact that this guidance will have on its trade receivables and financial arrangements when adopted; however, given the concentration of receivables with the U.S. government, the adoption is not expected to have a material effect on Perspecta’s financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350- 40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). ASU 2018-15 provides guidance for determining when a cloud computing arrangement includes a software license and makes changes to the requirements for capitalizing implementation costs incurred in a hosting arrangement that is as a service contract. The amendment is effective for public entities for fiscal years beginning after December 15, 2019, and early adoption is permitted. The update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company will adopt ASU 2018-15 on April 1, 2020 and is currently evaluating the method and impact of adoption on its financial statements and related disclosures. Other recently issued ASUs effective after September 30, 2019 are not expected to have a material effect on Perspecta’s financial statements.
Leases	Leases As described in Note 2 – “ Recent Accounting Pronouncements ,” effective April 1, 2019, we adopted ASC 842 using the optional transition method. In accordance with the optional transition method, we did not recast the prior period financial statements, and all prior period amounts and disclosures are presented under ASC 840. The Company leases certain real and personal property under non-cancelable operating leases. Lease assets under finance leases is comprised primarily of computers and related equipment. Finance lease obligations primarily consist of contractual arrangements with HPE Financial Services. Under ASC 842, an arrangement is determined to be a lease at inception if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. At inception, we determine whether the contract is or contains a lease and, if so, whether the lease should be classified as an operating or a finance lease. The Company recognizes a ROU asset and a lease liability based on the present value of the future minimum lease payments over the lease term at the commencement date, adjusted for any lease incentives, initial direct costs, and potential impairment. At the commencement date, a single discount rate is applied to a group of leases with the same durations. The rate is updated quarterly for new leases that commence during the period, unless a triggering event occurs requiring more frequent reassessment. We define the initial lease term to include renewal options determined to be reasonably certain. Lease assets are evaluated for impairment in a manner consistent with the treatment of other long-lived assets. Certain leases require us to pay property taxes, insurance and routine maintenance, which are included in variable lease expense. At September 30, 2019 , the Company did not have any lease agreements with residual value guarantees or material restrictions or covenants. The Company's lessor arrangements with its customers are immaterial to the results of operations and cash flows.

Summary of Pro Forma Information	The following unaudited pro forma financial information presents results as if the Spin-Off and the Mergers and the related financing had occurred on April 1, 2017. The historical consolidated financial information of Perspecta has been adjusted in the pro forma information to give effect to the events that are (1) directly attributable to the transactions, (2) factually supportable and (3) expected to have a continuing impact on the combined results. The effects of the Spin-Off are primarily attributable to interest expense associated with the incurrence of debt in connection with the Spin-Off. The effects of the Mergers primarily relate to amortization of acquired intangible assets. The consolidated financial information of Perspecta includes merger and integration-related costs that are not expected to recur and impact the combined results over the long term. The unaudited pro forma results do not reflect future events that have occurred or may occur after the transactions, including but not limited to, the impact of any actual or anticipated synergies expected to result from the Mergers. Accordingly, the unaudited pro forma financial information is not necessarily indicative of the results of operations as they would have been had the transactions been effected on April 1, 2017, nor is it necessarily an indication of future operating results.
