August 11 -- CSR Corporation’s (601766) shareholders, CSR Corporation Limited and CSR Corporation Investment and Management, announced that the company will extend their stock lock-up period by three years, reports China Business News, citing a company filing.

CSR Corporation’s 6.423 billion shares and CSR Corporation Investment and Management’s 93 million shares in the listed company will be tradable on August 18. However, in order to prevent the company’s stock price from further declining due to the Wenzhou train crash on July 23, the two shareholders decided to hold their shares until 2014.

CSR Corporation previously purchased 28 million shares in South Locomotive & Rolling on June 30, accounting for 0.02 percent of the company’s total share capital.
