Three former Orthofix executives fired last September over “offensive conduct” have filed arbitration claims against the medical device company alleging wrongful termination, Orthofix disclosed in its latest proxy statement.

Chief Legal Officer Patrick Keran, CEO Keith Valentine and Chief Financial Officer John Bostjancic contend that the Lewisville, Texas-based company fired them for cause even though their conduct did not meet the contractually applicable definition of the term.
