Photronics, a maker of components for semiconductors, disclosed after the markets closed Wednesday that it has placed Richelle Burr, its general counsel since 2010, on paid administrative leave.

News of the development, reported in a U.S. Securities and Exchange Commission filing, was sparse on details. Her work will be handled by outside counsel and other company personnel “during the pendency of an ongoing internal review regarding certain Company transactions and other matters,” the filing said.
