Wang Yung-ching (
Wang's three-year term as chairman of three of the group's four biggest units ends next month. Shareholders are slated to elect new boards in June.
The election revives concerns about a successor to the 89-year-old billionaire, who is the nation's richest man.
Wang, who has two sons and seven daughters, hasn't named a replacement to take over the reins of Formosa Plastics Group, whose units account for about 10 percent of the Taiwan Stock Exchange's value.

"We'll know who they are after the elections take place," he said.
