## Thalomid and Revlimid  Antitrust Litigation 

Beginning in November 2014, certain putative class action lawsuits were filed against Celgene in the U.S. District Court for the District of New Jersey alleging that Celgene violated various antitrust, consumer protection, and unfair competition laws by (a) allegedly securing an exclusive supply contract for the alleged purpose of preventing a generic manufacturer from securing its own supply of thalidomide active pharmaceutical ingredient, (b) allegedly refusing to sell samples of Thalomid  and Revlimid  brand drugs to various generic manufacturers for the alleged purpose of bioequivalence testing necessary for aNDAs to be submitted to the FDA for approval to market generic versions of these products, (c) allegedly bringing unjustified patent infringement lawsuits in order to allegedly delay approval for proposed generic versions of Thalomid and Revlimid , and/or (d) allegedly entering into settlements of patent infringement lawsuits with certain generic manufacturers that allegedly have had anticompetitive effects. The plaintiffs, on behalf of themselves and putative classes of third-party payers, are seeking injunctive relief and damages. The various lawsuits were consolidated into a master action for all purposes. In October 2017, the plaintiffs filed a motion for certification of two damages classes under the laws of thirteen states and the District of Columbia and a nationwide injunction class. Celgene filed an opposition to the plaintiffs’ motion and a motion for judgment on the pleadings dismissing all state law claims where the plaintiffs no longer seek to represent a class. In October 2018, the Court denied the plaintiffs’ motion for class certification and Celgene’s motion for judgment on the pleadings. In December 2018, the plaintiffs filed a new motion for class certification, which Celgene opposed. In July 2019, the parties reached a settlement under which all the putative class plaintiff claims would be dismissed with prejudice. In December 2019, after certain third-party payors who were members of the settlement class refused to release their potential claims and participate in the settlement, Celgene exercised its right to terminate the settlement agreement. No trial date has been set. 

## GOVERNMENT INVESTIGATIONS 

Like other pharmaceutical companies, BMS and certain of its subsidiaries are subject to extensive regulation by national, state and local authorities in the U.S. and other countries in which BMS operates. As a result, BMS, from time to time, is subject to various governmental and regulatory inquiries and investigations as well as threatened legal actions and proceedings. It is possible that criminal charges, substantial fines and/or civil penalties, could result from government or regulatory investigations. 

## ENVIRONMENTAL PROCEEDINGS 

As previously reported, BMS is a party to several environmental proceedings and other matters, and is responsible under various state, federal and foreign laws, including CERCLA, for certain costs of investigating and/or remediating contamination resulting from past industrial activity at BMS’s current or former sites or at waste disposal or reprocessing facilities operated by third parties. 

## CERCLA Matters 

With respect to CERCLA matters for which BMS is responsible under various state, federal and foreign laws, BMS typically estimates potential costs based on information obtained from the U.S. Environmental Protection Agency, or counterpart state or foreign agency and/or studies prepared by independent consultants, including the total estimated costs for the site and the expected cost-sharing, if any, with other “potentially responsible parties,” and BMS accrues liabilities when they are probable and reasonably estimable. BMS estimated its share of future costs for these sites to be $68.6 million at December 31, 2019, which represents the sum of best estimates or, where no best estimate can reasonably be made, estimates of the minimal probable amount among a range of such costs (without taking into account any potential recoveries from other parties). The amount includes the estimated costs for any additional probable loss associated with the previously disclosed North Brunswick Township High School Remediation Site.
