Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 8 — Commitments and Contingencies In July 2016, the Company entered into two separate agreements with The Boeing Company (Boeing) for the construction and purchase of the Company’s first two ViaSat-3 class satellites and the integration of Viasat’s payload technologies into the satellites. In July 2019, the Company entered into an agreement with Boeing for the construction and purchase of a third ViaSat-3 class satellite and the integration of Viasat’s payload technologies into the satellite. From time to time, the Company is involved in a variety of claims, suits, investigations and proceedings arising in the ordinary course of business, including government investigations and claims, and other claims and proceedings with respect to intellectual property, breach of contract, labor and employment, tax and other matters. Such matters could result in fines; penalties, compensatory, treble or other damages; or non-monetary relief. A violation of government contract laws and regulations could also result in the termination of its government contracts or debarment from bidding on future government contracts. Although claims, suits, investigations and proceedings are inherently uncertain and their results cannot be predicted with certainty, the Company believes that the resolution of its current pending matters will not have a material adverse effect on its business, financial condition, results of operations or liquidity. The Company has contracts with various U.S. Government agencies. Accordingly, the Company is routinely subject to audit and review by the DCMA, the DCAA and other U.S. Government agencies of its performance on government contracts, indirect rates and pricing practices, accounting and management internal control business systems, and compliance with applicable contracting and procurement laws, regulations and standards. An adverse outcome to a review or audit or other failure to comply with applicable contracting and procurement laws, regulations and standards could result in material civil and criminal penalties and administrative sanctions being imposed on the Company, which may include termination of contracts, forfeiture of profits, triggering of price reduction clauses, suspension of payments, significant customer refunds, fines and suspension, or a prohibition on doing business with U.S. Government agencies. In addition, if the Company fails to obtain an “adequate” determination of its various accounting and management internal control business systems from applicable U.S. Government agencies or if allegations of impropriety are made against it, the Company could suffer serious harm to its business or its reputation, including its ability to bid on new contracts or receive contract renewals and its competitive position in the bidding process. The Company’s incurred cost audits by the DCAA have not been concluded for fiscal years 2019 or 2020. As of December 31, 2020, the DCAA had completed its incurred cost audit for fiscal years 2004 and 2016 and approved the Company’s incurred costs for those fiscal years, as well as approved the Company’s incurred costs for fiscal years 2005 through 2015, 2017 and 2018 without further audit based on the determination of low risk. Although the Company has recorded contract revenues subsequent to fiscal year 2018 based upon an estimate of costs that the Company believes will be approved upon final audit or review, the Company does not know the outcome of any ongoing or future audits or reviews and adjustments, and if future adjustments exceed the Company’s estimates, its profitability would be adversely affected. As of December 31, 2020 and March 31, 2020, the Company had $8.8 million and $7.8 million, respectively, in contract-related reserves for its estimate of potential refunds to customers for potential cost adjustments on several multi-year U.S. Government cost reimbursable contracts. This reserve is classified as either an element of accrued liabilities or as a reduction of unbilled accounts receivable based on the status of the related contracts.
