The country's five major banking groups - Shinhan, KB, Hana, Woori and NongHyup - are drawing attention over whether they will replace their outside directors whose terms will expire next month amid the government's push for an overhaul of the groups' governance structures. Thirty out of 40 outside directors at the five companies will see their tenures end. And while they can serve up to six years as stipulated by the commerce law, industry sources say it remains uncertain whether they will win approvals from shareholders and boards of directors this year.
