They’re first grade in securities.” Roger has a particularly strong record of success representing foreign issuers in U.S. courts and handling matters with complex cross-border or international dimensions. Roger’s experience is enhanced by his close partnerships with Cleary’s tightly integrated global teams. He was a lead partner representing Petrobras in the largest U.S. securities class action ever brought against a foreign issuer (securing a favorable class action settlement in 2018 that received final approval in 2019), as well as in more than 35 separate opt-out individual actions; lead partner successfully representing the special committee of Synutra (China) in one of the most significant Delaware Supreme Court decisions of 2018; and successfully secured dismissals in matters against foreign defendants DBS Satellite Services (YES) (Israel) and Sky Solar (China). Companies rely on Roger to resolve complex cases with creative advice and advocacy. Most recently, he secured a rare summary judgment ruling in favor of Merrill Lynch in a complex cross-border fraud claim arising out of its sale of a CDO to an Isle of Jersey investment vehicle structured by a German bank. In another recent matter, he favorably litigated and resolved Delaware section 220 books and records litigation (through trial) and appraisal litigation on behalf of Genting (Malaysia) in connection with its acquisition of Empire Resorts.

He is currently representing U.S.-based companies International Flavors & Fragrances and Allergan in securities class actions, as well as Citigroup defendants in class action litigation related to ICE LIBOR.

Other major clients include Assured Guaranty, Atlantic Power, Bank of America, Dun & Bradstreet, Baker Hughes, Google, Kindred Healthcare, Lowe’s, T-Mobile, The Raine Group, Open Text, and Tech Data.
