Under a plan unveiled in July, SAIC Motor Corp, the country's top car maker, transferred key operations to its unit Shanghai Auto in exchange for 19.09 billion yuan of new shares in the unit, securing a fund-raising channel to aid the group's global expansion.
Shanghai Auto now has a market value of 53.65 billion yuan ($6.8 billion) based on Tuesday's closing share price, making it one of the 20 most heavily capitalized companies on the domestic stock markets.
The restructuring significantly increases Shanghai Auto's net asset value and profits, the company said. Had the deal been in effect during the first half of 2006, it would have raised Shanghai Auto's earnings by 28.5 percent for the period.
Assets injected into Shanghai Auto include SAIC's stakes in ventures with General Motors and Volkswagen AG. Shanghai Auto already owned a fifth of GM's main car venture in China.
