SEOUL, Dec. 18 -- Cheil Industries, the de-facto holding company of South Korea's largest conglomerate Samsung Group, debuted on the local main bourse Thursday, with a record- high subscription to its initial public offering (IPO) shares in the country's history.

During last week's pre-order session, 30.06 trillion won (27.3 billion U.S. dollars) was offered to subscribe for the Cheil Industries IPO shares, topping the previous high of 19.22 trillion won for IPO shares in 2010 of Samsung Life Insurance, the group's flagship financial unit and the country's biggest life insurer.

Cheil Industries closed at 113,000 won, more than doubling the IPO price of 53,000 won and up 6.6 percent from its opening price of 106,000 won.

The company, which is 45.6 percent owned by Samsung Group owner Lee Kun-hee and his three children, got to have the 14th-largest market capitalization with 15.26 trillion won.

Chairman Lee has a 3.7 percent stake in Cheil Industries, with his only son and heir apparent Jae-yong holding a 25.1 percent stake. Lee's two daughters own 8.4 percent stakes in the company each.

Samsung has sought to made public some of its units and transform business portfolio to smoothly transfer the management control from Chairman Lee to his three children since Lee was hospitalized for a heart attack in May.

Trading volume of Cheil Industries shares in its market debut was 1.37 trillion won, surpassing the previous high of 1.35 trillion won for IPO shares of Samsung SDS, which was listed on the main bourse last month.

Cheil Industries, formerly known as Samsung Everland, is seen as the group's de-facto holding company as it has a 20 percent stake in Samsung Life Insurance, a major shareholder of Samsung Electronics.
