Throughout the 1990s, Opel had also been the source of many Holden models. To increase profitability, Holden looked to the South Korean Daewoo brand for replacements after acquiring a 44.6 percent stake—worth US$251 million—in the company in 2002 as a representative of GM. This was increased to 50.9 percent in 2005, but when GM further increased its stake to 70.1 percent around the time of its 2009 Chapter 11 reorganisation, Holden's interest was relinquished and transferred to another (undisclosed) part of GM.
