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.
