Barry R. Ostrager is a Senior Partner at Simpson Thacher & Bartlett LLP and former Chair of Simpson Thacher’s Litigation Department from 1999 to 2011.  Mr. Ostrager has successfully tried to verdict five cases in which more than a billion dollars was at issue.  He has also successfully tried dozens of cases to verdict and argued scores of appeals throughout the country.  He has been prominently involved in the trials of many high-profile securities, antitrust, insurance and other commercial cases.  Mr. Ostrager was lead trial counsel for Swiss Re in the highly publicized insurance coverage dispute involving the World Trade Center tragedy which resulted in a unanimous jury verdict in favor of Swiss Re, and lead counsel for Hanwha in a multi-billion dollar dispute with the Korean government that was the subject of a multi-week trial.  Mr. Ostrager successfully argued before the United States Supreme Court the closely followed Epstein v. Matsushita case that arose out of Matsushita’s successful tender offer for MCA, Inc.  In 2010, he successfully argued again before the Supreme Court the Travelers v. Bailey case, which resolved important issues relating to the rights of settling insurers in asbestos-related bankruptcy.  He also successfully represented Andersen Consulting against a $14 billion claim by Arthur Andersen in connection with Andersen Consulting’s successful bid to win a separation without cost from the Andersen Worldwide organization in the largest ICC arbitration in history. 


Recently his trial victories include a member of the Royal Jordanian family, in a dispute related to Iraqi war defense contracts, a $110 million jury verdict for Gray Development Group in Arizona state court related to failed efforts to develop a 41-acre apartment complex in Phoenix, and achieving a confidential settlement on behalf of Ingersoll Rand after a two and half week trial in New Jersey federal court involving more than $100 million in employment related claims by former Ingersoll Rand employees.   Earlier this year, Mr. Ostrager prevailed on behalf of Travelers in an insurance coverage trial he conducted in California Superior Court against Plant Insulation Company, a former Travelers insured, which was seeking limitless coverage from Travelers for asbestos personal injury claims. 


Mr. Ostrager has been prominently involved in supervising the firm’s major insurance and reinsurance practices in both its New York and Los Angeles offices.  He has been lead trial counsel in more than a dozen major insurance coverage cases, including Shell Oil Co. v. Winterthur Swiss Insurance Company, a multi-billion dollar environmental insurance coverage dispute in which the jury returned a verdict for the insurers after a sixteen-month trial.     


Mr. Ostrager is co-author of the Handbook on Insurance Coverage Disputes (Aspen Law & Business 2012), a widely-used, three-volume treatise now in its sixteenth edition.  Mr. Ostrager is also a frequent lecturer on federal securities law and insurance law.
