More broadly, South Korea's long-established chaebol system has drawn fire in recent years for sustaining family-run fiefdoms at the expense of shareholders. Samsung, as the largest of the chaebols, has attracted criticism from activist investors including Paul Elliott Singer, who last year launched one of the country's biggest proxy fights when he contested the merger of two key Samsung Group affiliates. While that deal eventually went through, Singer is now pushing for more change at Samsung Electronics.
