UMC refuted the newspaper report. The company said Chang unloaded the 3 million UMC shares during the period between Aug. 22 and Sept. 15 as he planned in a request to the Taiwan Stock Exchange.
"Chang has not sold any share since then. It is not true that Chang sold the UMC shares during the period between September 28 and October 5. He is not involved in any insider trading," the statement read.
Chang planned to use the proceeds to pay his housing mortgage and taxes, the statement said.
