Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation We are routinely involved in legal proceedings, claims, disputes, regulatory matters and governmental inspections or investigations arising in the ordinary course of or incidental to our business, including those noted below in this section. Additionally, as a result of the impact of COVID-19, litigation claims, enforcement actions, regulatory actions and investigations, including, but not limited to, those arising from personal injury and loss of life, have been and may, in the future, be asserted against us. The existing assertions are in their initial stages. We expect many of these claims and actions, or any settlement of these claims and actions, to be covered by insurance and historically the maximum amount of our liability, net of any insurance recoverables, has been limited to our self-insurance retention levels. We record provisions in the consolidated financial statements for pending litigation when we determine that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. Legal proceedings and government investigations are subject to inherent uncertainties, and unfavorable rulings or other events could occur. Unfavorable resolutions could involve substantial monetary damages. In addition, in matters for which conduct remedies are sought, unfavorable resolutions could include an injunction or other order prohibiting us from selling one or more products at all or in particular ways, precluding particular business practices or requiring other remedies. An unfavorable outcome might result in a material adverse impact on our business, results of operations, financial position or liquidity. As previously disclosed, on May 2, 2019, an action was filed against Carnival Corporation in the U.S. District Court for the Southern District of Florida under Title III of the Cuban Liberty and Democratic Solidarity Act, also known as the Helms-Burton Act. On April 17, 2020, the court reversed its dismissal of the virtually identical cases brought by Havana Docks Corporation against other cruise lines, and at that time, denied our pending motion for reconsideration on our prior motion to dismiss and allowed the plaintiff to file an amended complaint. As a result, on April 27, 2020, we filed a motion seeking leave to appeal. On May 18, 2020, we filed a motion to dismiss the plaintiff’s amended complaint and the briefing is now complete. On June 26, 2020, the court denied our motion seeking leave to appeal and denied our motion to stay discovery for 90 days. Contingent Obligations – Indemnifications Some of the debt contracts we enter into include indemnification provisions obligating us to make payments to the counterparty if certain events occur. These contingencies generally relate to changes in taxes or changes in laws which increase our lender’s costs. There are no stated or notional amounts included in the indemnification clauses, and we are not able to estimate the maximum potential amount of future payments, if any, under these indemnification clauses. Other Contingencies We have agreements with a number of credit card processors that transact customer deposits related to our cruise vacations. Certain of these agreements allow the credit card processors to request under certain circumstances that we provide a reserve fund in cash. Although the agreements vary, these requirements may generally be satisfied either through a withheld percentage of customer payments or providing cash funds directly to the card processor. As of May 31, 2020, we have been requested to provide reserve funds of $27 million and have had $14 million of customer deposits withheld to satisfy these requirements. We expect the funds withheld under these agreements will be approximately $80 million per month up to a maximum of $600 million. COVID-19 Actions Class Actions On April 7, 2020, Paul Turner, a former guest from Costa Luminosa, filed a purported class action against Costa Crociere, S.p.A. (“Costa”) and Costa Cruise Line, Inc. in the U.S. District Court for the Southern District of Florida seeking compensation based on alleged severe emotional distress associated with being exposed to COVID-19 onboard and/or alleged physical injuries and severe emotional distress associated with contracting COVID-19 onboard. The action asserts claims for negligence, negligent infliction of emotional distress, intentional infliction of emotional distress, misleading advertising in violation of Florida Statute § 817.41, and negligent misrepresentation. On April 8, 2020, numerous former guests from Grand Princess filed a purported class action against Carnival Corporation & plc and two of our subsidiaries, Princess Cruise Lines Ltd. (“Princess”) and Fairline Shipping International Corporation, Ltd. (“Fairline”), seeking compensation based on alleged severe emotional distress associated with being exposed to COVID-19 onboard, contracting COVID-19 onboard, and/or contracting COVID-19 while onboard and subsequently passing away as a result of COVID-19. The complaint asserts claims for negligence and gross negligence. This action was originally filed in the U.S. District Court for the Northern District of California, however, on May 4, 2020, the parties entered into a stipulation, which was approved by the court on May 5, 2020, that the case be transferred to the U.S. District Court for the Central District of California pursuant to the terms of the plaintiffs’ ticket contracts. Following the transfer, the plaintiffs filed a First Amended Complaint on June 2, 2020 that named Carnival Corporation and Carnival plc as defendants in place of Carnival Corporation & plc and removed Fairline as a defendant, and also added claims for negligent and intentional infliction of emotional distress. On May 27, 2020, Service Lamp Corporation Profit Sharing Plan filed a purported class action in the U.S. District Court for the Southern District of Florida against Carnival Corporation, Arnold W. Donald and David Bernstein on behalf of all purchasers of Carnival Corporation securities between January 28 and May 1, 2020. On June 3, 2020, John P. Elmensdorp filed a purported class action in the U.S. District Court for the Southern District of Florida against the same defendants, and adding Micky Arison as a defendant. This action is on behalf of all purchasers of Carnival Corporation securities between September 26, 2019 and April 30, 2020. These complaints allege that the defendants violated Sections 10(b) and 20(a) of the Securities and Exchange Act of 1934 by making misrepresentations and omissions related to Carnival Corporation’s COVID-19 knowledge and response, and seek to recover unspecified damages and equitable relief for the alleged misstatements and omissions. On June 4, 2020, another group of former guests from Grand Princess filed a purported class action against Carnival Corporation, Carnival plc, and Princess in the U.S. District Court for the Central District of California, seeking compensation based on the same factual theories presented in the class actions described above. The action asserts claims for negligence, gross negligence, negligent infliction of emotional distress and intentional infliction of emotional distress. On June 4, 2020, Gregory Eicher, a former guest from Grand Princess filed a purported class action against Princess in the U.S. District Court for the Central District of California, seeking compensation based on alleged severe emotional distress associated with being exposed to COVID-19 onboard and/or alleged physical injuries and severe emotional distress associated with contracting COVID-19 onboard. The action asserts claims for negligence, negligent infliction of emotional distress and intentional infliction of emotional distress. On June 4, 2020, numerous former guests from Ruby Princess filed a purported class action against Princess in the U.S. District Court for the Central District of California, seeking compensation based on alleged severe emotional distress associated with being exposed to COVID-19 onboard and/or alleged physical injuries and severe emotional distress associated with contracting COVID-19 onboard. The action asserts claims for negligence, negligent infliction of emotional distress, and intentional infliction of emotional distress. On June 24, 2020, Leonard C. Lindsay and Carl E.W. Zehner, former guests from Zaandam filed a purported class action in the U.S. District Court for the Western District of Washington at Seattle against Carnival Corporation, Carnival plc, Holland America Line, Inc., and Holland American Line – U.S.A., Inc. seeking compensation based on alleged serious personal injury and emotional distress, for those contracting COVID-19 and those claiming exposure to COVID-19. The action asserts claims for negligence, gross negligence, negligent infliction of emotional distress and intentional infliction of emotional distress. This case also seeks injunctive relief in the form of certain disclosures to passengers and medical monitoring. We believe that the claims asserted in these actions are without merit and are taking proper actions to defend against them. Individual Actions Between March 9, 2020 and July 7, 2020, more than 100 former U.S. guests who sailed onboard various vessels, including, but not limited to, Diamond Princess, Grand Princess, or Ruby Princess, filed individual actions against Princess, and in some actions also against Carnival Corporation and/or Carnival plc in the U.S. District Court for the Central District of California. On June 11, 2020, a former guest who sailed onboard Coral Princess filed an action against Princess, Carnival Corporation and Carnival plc in the Superior Court of California, County of Los Angeles. These lawsuits include tort claims based on a variety of theories, including but not limited to negligence and failure to warn. The plaintiffs in these cases allege a variety of injuries: some plaintiffs allege only emotional distress, while others allege injuries arising from testing positive for COVID-19. A smaller number of cases include wrongful death claims. The defendants will respond to each of these complaints individually. Motions to dismiss were filed on June 2, 2020 in the individual actions against Princess that allege emotional distress associated with exposure to COVID-19 while onboard. In addition, between April 7, 2020 and July 7, 2020, four former U.S. guests from Costa Luminosa filed individual actions against Costa in the U.S. District Court for the Southern District of Florida or the Circuit Court in and for the 11^th Judicial Circuit in and for Miami-Dade County. These plaintiffs seek compensation on factual allegations similar to those presented by the former U.S. guests who have filed the purported class actions described above. The defendants will respond to each of these complaints individually. On June 16, 2020, Patricia Vickers, on behalf of the Estate of Jessie Vickers, a former guest from Carnival Ecstasy, filed an action against Carnival Corporation in the U.S. District Court for the Southern District of Georgia seeking compensation based on a claim alleging wrongful death as a result of contracting COVID-19. The action asserts a claim for negligence. On June 30, 2020, Kenneth and Nora Hook, former guests from Zaandam, filed an action against Holland America Line N.V. in the U.S. District Court for the Western District of Washington at Seattle seeking compensation in the form of economic and non-economic damages relating to Mr. Hook contracting COVID-19 and punitive damages. The action asserts a claim for negligence. These individual actions seek monetary and punitive damages but do not specify exact amounts. We are taking proper actions to defend against them. Governmental Inquiries and Investigations Federal, state and non-U.S. governmental agencies and officials are investigating or otherwise seeking information, testimony and/or documents, regarding COVID-19 incidents and related matters, including, but not limited to, those noted below. We are investigating these matters internally and are cooperating with all requests. The investigations could result in the imposition of civil and criminal penalties in the future. In March and April, 2020, there were several inquiries or investigations initiated by foreign governmental authorities related to Ruby Princess, including authorities in Australia and New Zealand. In May 2020, we received requests for information from the U.S. House of Representatives Transportation and Infrastructure Committee and the Senate Committee on Commerce, Science, and Transportation related to COVID-19 matters. In April 2020, the Federal Maritime Commission announced that it would lead a fact finding investigation to identify commercial measures passengers cruise lines can adopt to mitigate COVID-19 related impacts.
