Press release content: So as to respect the market, be more in line with international standards, and create greater efficiency in the market, price fluctuation limit has been relaxed from 7% to 10%, starting on June 1, 2015. On May 2, the collateral maintenance ratio for each margin account was adjusted from 120% to 130%. A more relaxed price fluctuation limit will serve as to accelerate stock price reaction and increase market efficiency. Furthermore, it will decrease the chances of reaching the price limit and discouraging investors chasing the market.

The appropriate adjustment of price fluctuation limit includes the synchronized adjustment of all products. The price fluctuation limit of odd-lot trading and block trading has been adjusted from 7% to 10%. The standard purchasing price price-ceiling for the securities finance industry has been increased from 7%~15% to 10%~20%. Strengthening risk control includes adjusting the range for day trading from 120% to 130%. The securities lending collateral for securities firms has been increased from 114% to 120%. When securities firms and other institutions in the securities finance industry conduct securities lending, the initial margin and maintenance margin for investors will be 140% and 120%, respectively. Professional institutional investors can agree on a rate with the securities firms and are not restricted to the rate limit. The maintenance margin for T+5 type securities borrowing and lending was adjusted from 100%~125% to 100%~130%. The maintenance margin for the six-month type of securities borrowing and lending has increased from 120% to 130%.
