The performance guarantee ratio is specifically divided into warning line, disposal line and recovery line. When it is lower than the "warning line", it is suggested that you make supplementary pledge (guaranteed recovery) or repurchase in advance to make the value reach the guaranteed recovery level; Below the "disposal line", please supplement the pledge or buy back in time. If the minimum performance guarantee ratio is reached or lower on T-day, and you have not submitted supplementary transactions or repurchased in advance before T+ 1 day 14:00, the company will start the default disposal process after T+ 1 day/4: 00.
