Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE H – COMMITMENTS AND CONTINGENCIES The medical device market in which we participate is largely technology driven. As a result, intellectual property rights, particularly patents and trade secrets, play a significant role in product development and differentiation. Over the years, there has been litigation initiated against us by others, including our competitors, claiming that our current or former product offerings infringe patents owned or licensed by them. Intellectual property litigation is inherently complex and unpredictable. In addition, competing parties frequently file multiple suits to leverage patent portfolios across product lines, technologies and geographies and to balance risk and exposure between the parties. In some cases, several competitors are parties in the same proceeding, or in a series of related proceedings, or litigate multiple features of a single class of devices. These dynamics frequently drive settlement not only for individual cases, but also for a series of pending and potentially related and unrelated cases. Although monetary and injunctive relief is typically sought, remedies and restitution are generally not determined until the conclusion of the trial court proceedings and can be modified on appeal. Accordingly, the outcomes of individual cases are difficult to time, predict or quantify and are often dependent upon the outcomes of other cases in other geographies. During recent years, we successfully negotiated closure of several long-standing legal matters and have received favorable rulings in several other matters; however, there continues to be outstanding intellectual property litigation. Adverse outcomes in one or more of these matters could have a material adverse effect on our ability to sell certain products and on our operating margins, financial position, results of operations and/or liquidity. In the normal course of business, product liability, securities and commercial claims are asserted against us. Similar claims may be asserted against us in the future related to events not known to management at the present time. We maintain an insurance policy providing limited coverage against securities claims and we are substantially self-insured with respect to product liability claims and fully self-insured with respect to intellectual property infringement claims. The absence of significant third-party insurance coverage increases our potential exposure to unanticipated claims or adverse decisions. Product liability claims, securities and commercial litigation and other legal proceedings in the future, regardless of their outcome, could have a material adverse effect on our ability to sell certain products and on our operating margins, financial position, results of operations and/or liquidity. In addition, like other companies in the medical device industry, we are subject to extensive regulation by national, state and local government agencies in the U.S. and other countries in which we operate. From time to time we are the subject of qui tam actions and governmental investigations often involving regulatory, marketing and other business practices. These qui tam actions and governmental investigations could result in the commencement of civil and criminal proceedings, substantial fines, penalties and administrative remedies and have a material adverse effect on our financial position, results of operations and/or liquidity. In accordance with FASB ASC Topic 450, Contingencies, we accrue anticipated costs of settlement, damages, losses for product liability claims and, under certain conditions, costs of defense, based on historical experience or to the extent specific losses are probable and estimable. Otherwise, we expense these costs as incurred. If the estimate of a probable loss is a range and no amount within the range is more likely, we accrue the minimum amount of the range. Our accrual for legal matters that are probable and estimable was $455 million as of March 31, 2021 and $569 million as of December 31, 2020 and includes certain estimated costs of settlement, damages and defense. The decrease in our legal accrual was mainly due to settlement payments associated with product liability cases or claims related to transvaginal surgical mesh products. A portion of our legal accrual is already funded through our qualified settlement fund (QSF), which is included in restricted cash and restricted cash equivalents in Other current assets of $184 million as of March 31, 2021 and $208 million as of December 31, 2020. Refer to Note F – Supplemental Balance Sheet Information for additional information. We recorded litigation-related net charges of $4 million during the first quarter of 2021, related to the finalization of a settlement with a coalition of state attorneys general associated with claims regarding our transvaginal surgical mesh products. We did not record any litigation-related net charges during the first quarter of 2020. We record certain legal and product liability charges, credits and costs of defense, which we consider to be unusual or infrequent and significant as Litigation-related net charges (credits) in our accompanying unaudited consolidated financial statements. All other legal and product liability charges, credits and costs are recorded within Selling, general and administrative expenses in our accompanying unaudited consolidated statements of operations. We continue to assess certain litigation and claims to determine the amounts, if any, that management believes will be paid as a result of such claims and litigation and, therefore, additional losses may be accrued and paid in the future, which could materially adversely impact our operating results, cash flows and/or our ability to comply with our financial covenant. In management's opinion, we are not currently involved in any legal proceedings other than those disclosed in our most recent Annual Report on Form 10-K and those specifically identified below, which, individually or in the aggregate, could have a material adverse effect on our financial condition, operations and/or cash flows. Unless included in our legal accrual or otherwise indicated below, a range of loss associated with any individual material legal proceeding cannot be reasonably estimated. Patent Litigation On October 28, 2015, the Company filed suit against Cook Group Limited and Cook Medical LLC (collectively, “Cook”) in the United States District Court for the District of Delaware (1:15-cv-00980) alleging infringement of certain Company patents regarding Cook’s Instinct Endoscopic Hemoclip. The case was transferred to the District Court for the Southern District of Indiana. Cook filed seven Inter Partes Review (“IPR”) requests with the U.S. Patent and Trademark Office (USPTO) against the four asserted patents. All IPRs have concluded and Cook and the Company both appealed the Patent Office’s IPR decisions to the Federal Circuit Court of Appeals. On April 30, 2020, the U.S. Court of Appeals ruled that claims from two of the Company's patents remain valid, remanding two of the patents for further review by the USPTO’s Patent Trial and Appeal Board. In November 2020, the Patent Office issued remand rulings invalidating several additional claims. The district court stayed the case pending the appeals court decision on the IPRs, which is now complete. The case is proceeding before the United States District Court for the Southern District of Indiana, with the Company asserting two patents against Cook. Trial is anticipated in 2022. On February 23, 2021, Nevro Corp. (“Nevro”) filed a complaint against the Company in the United States District Court for the District of Delaware (21-cv-258). The complaint alleges infringement of five Nevro patents by certain of the Company’s spinal cord stimulation systems. Product Liability Litigation As of April 21, 2021, approximately 54,000 product liability cases or claims related to transvaginal surgical mesh products designed to treat stress urinary incontinence and pelvic organ prolapse have been asserted against us. As of April 21, 2021, we have entered into master settlement agreements in principle or are in the final stages of entering one with certain plaintiffs' counsel to resolve an aggregate of approximately 52,000 cases and claims, adjusted to reflect the Company’s analysis of expected non-participation and duplicate claims. These master settlement agreements provide that the settlement and distribution of settlement funds to participating claimants are conditional upon, among other things, achieving minimum required claimant participation thresholds. Of the approximately 52,000 cases and claims, approximately 48,000 have met the conditions of the settlement and are final. All settlement agreements were entered into solely by way of compromise and without any admission or concession by us of any liability or wrongdoing. The pending cases are in various federal and state courts in the U.S. Generally, the plaintiffs allege personal injury associated with use of our transvaginal surgical mesh products. The plaintiffs assert design and manufacturing claims, failure to warn, breach of warranty, fraud, violations of state consumer protection laws and loss of consortium claims. Over 3,100 of the cases were specially assigned to one judge in state court in Massachusetts. On February 7, 2012, the Judicial Panel on Multi-District Litigation (MDL) established MDL-2326 in the U.S. District Court for the Southern District of West Virginia and transferred the federal court transvaginal surgical mesh cases to MDL-2326 for coordinated pretrial proceedings. The Court issued an Order closing the MDL on February 11, 2021, as all cases that had been pending were dismissed or remanded to courts of primary jurisdiction. Outside the United States, there are fewer than 70 claims in the United Kingdom. In the first quarter of 2021, two class actions were filed against the Company in Australia, where there are fewer than 125 claims. There are also fewer than 10 cases in Canada, inclusive of one certified class action, which has settled and received Court approval. On April 16, 2019, the U.S. Food and Drug Administration (FDA) ordered that all manufacturers of surgical mesh products indicated for the transvaginal repair of pelvic organ prolapse stop selling and distributing their products in the United States immediately, stemming from the FDA’s 2016 reclassification of these devices to class III (high risk) devices, and as a result, the Company ceased global sales and distribution of surgical mesh products indicated for transvaginal pelvic organ prolapse. In April 2021 the Company's Board of Directors received a shareholder demand under section 220 of the Delaware General Corporation Law, for inspection of books and records. The Company has notified our insurer and retained counsel to respond to the demand. We have established a product liability accrual for known and estimated future cases and claims asserted against us as well as with respect to the actions that have resulted in verdicts against us and the costs of defense thereof associated with our transvaginal surgical mesh products. While we believe that our accrual associated with this matter is adequate, changes to this accrual may be required in the future as additional information becomes available. While we continue to engage in discussions with plaintiffs’ counsel regarding potential resolution of pending cases and claims and intend to vigorously contest the cases and claims asserted against us that do not settle, the final resolution of the cases and claims is uncertain and could have a material impact on our results of operations, financial condition and/or liquidity. Initial trials involving our transvaginal surgical mesh products have resulted in both favorable and unfavorable judgments for us. We do not believe that the judgment in any one trial is representative of potential outcomes of all cases or claims related to our transvaginal surgical mesh products. We are currently named a defendant in 129 filed product liability cases involving our Greenfield Vena Cava Filter, which we discontinued marketing and active selling in the fourth quarter of 2018, alleging various injuries, including perforation of the vena cava, post-implant deep vein thrombosis, fracture, and other injuries. Most of the filed cases are part of a consolidated matter in Middlesex County, Massachusetts. We have received notice of an additional 553 claims, none of which have been filed. Other Proceedings On September 6, 2019, Boston Scientific Corporation, Boston Scientific Scimed, Inc., and Fortis Advisors, LLC, as a Securityholder Representative for the former Securityholders of nVision Medical Corp. filed a declaratory judgment action against BioCardia, Inc. in the United States District Court for the Northern District of California to address threats and allegations by BioCardia challenging inventorship and ownership of various patents that Boston Scientific Corporation acquired through an April 13, 2018 merger with nVision as well as related threats and allegations by BioCardia of trade secret misappropriation and unjust enrichment. On December 11, 2019, BioCardia filed an amended answer and counterclaims. On April 23, 2020, BioCardia filed a complaint against nVision, which had not been named as a defendant in the original case. On May 22, 2020, BioCardia amended its complaint against nVision to add twenty former nVision shareholders as defendants. On August 20, 2020, BioCardia again amended its complaint against Boston Scientific Corporation/Boston Scientific Scimed, Inc./Fortis Advisors, LLC and its complaint against nVision/nVision shareholders. On April 8, 2021, the parties settled the dispute, and, on April 12, 2021, the parties filed stipulations with the court to dismiss the remaining legal proceedings. We expect the settlement will not result in any material benefit or liability to the Company. On December 4, 2020 Enrique Jevons, individually and on behalf of all others similarly situated, filed a class action complaint against the Company, Michael F. Mahoney and Daniel J. Brennan, stemming from the recall and retirement of the LOTUS Edge™ Aortic Valve System (LOTUS System) in United States District Court for the Eastern District of New York. On December 14, 2020, the parties agreed to transfer the case to the United States District Court for the District of Massachusetts. On December 16, 2020, Mariano Errichiello, individually and on behalf of all other similarly situated, filed a second, materially similar class action complaint against the Company, Michael F. Mahoney, Joseph M. Fitzgerald, and Daniel J. Brennan in the United States District Court for the District of Massachusetts. Subsequently, on March 30, 2021, the Court consolidated the two actions, and appointed Mariano Errichiello as the lead plaintiff. Counsel for Mr. Errichiello are required to file an Amended Complaint on or before June 4, 2021, in response to which the Company expects to bring a Motion to Dismiss. On December 15, 2020, the Securities and Exchange Commission’s Boston Regional Office (Boston SEC) notified the Company that it is conducting an investigation related to the Company’s decision to retire the LOTUS System, and issued a voluntary request for documents and information related to that decision. On February 10, 2021, the Boston SEC issued a second voluntary request for additional documents and information. The Company is cooperating fully with the investigation. On February 8, 2021, the Company received a letter from The Vladimir Gusinsky Revocable Trust, a shareholder, demanding that the Company’s Board of Directors conduct an investigation into actions by the Company’s directors and executive officers regarding statements made about the effectiveness and commercial viability of the LOTUS System. The Trust subsequently agreed to stay its demand, pending the outcome of any dispositive motion against the Amended Complaint in the class action complaint described above. Matters Concluded Since December 31, 2020 On February 23, 2015, a judge for the Court of Modena (Italy) ordered a trial for the Company and three of its employees, as well as numerous other defendants charged in criminal proceedings. The charges arise from allegations that the defendants made improper donations to certain healthcare providers and other employees of the Hospital of Modena in order to induce them to conduct unauthorized clinical trials, as well as related government fraud in relation to the financing of such clinical trials. A trial began on February 24, 2016. On November 10, 2017, the Court issued a ruling that convicted one Company employee but acquitted two others and levied a fine of €245 thousand against us and imposed joint and several civil damages of €620 thousand on all defendants. We continue to deny these allegations, and timely appealed the decision on May 10, 2018. On November 9, 2020, the Court of Appeal in Bologna reversed the judgements against the Company and its employee and acquitted them of all charges. This judgment of acquittal became final as to the Company and its employee on April 15, 2021 when the prosecution chose not to appeal. During the fourth quarter of 2013, we received written discovery requests from certain state attorneys general regarding our transvaginal surgical mesh products and related alleged violations of states’ consumer protection statutes. On December 12, 2019, the Mississippi Attorney General filed suit against us in a Mississippi state court alleging violations of the Mississippi Consumer Protection Act. In the fourth quarter of 2020 and the first quarter of 2021, we reached settlements with 48 states, including Mississippi, and the District of Columbia. These settlements were finalized in March of 2021.
