SK Group runs SK Hynix, the semiconductor giant that supplies chips to Nvidia and recently made a record-setting debut on the US stock market. Chey's lawyers said "Chairman Chey Tae-won is deeply sorry in that [the divorce] proceedings so far have caused concern to many people. The court had determined that the strongman had given Chey 30bn Korean won from his slush fund in 1991, and told Chey to pay 1.38tn to his ex-wife. As SK Hynix's value soared, the SK Group and its chairman Chey's status also rose. The BBC has contacted SK Group for comment.
