How long before delisting was the net assets negative?

According to the Proposal of Shanghai Stock Exchange on Perfecting the Delisting System of Listed Companies in Shanghai Stock Exchange, listed companies will be warned of delisting risk if their net assets are negative at the end of the last year; If the net assets at the end of the last two years are all negative, the listing of its shares shall be terminated.

The Shanghai Stock Exchange believes that compared with other delisting financial indicators, the setting of net assets indicators lacks the suspension of listing. Considering the balance of system design, we decided to adopt relevant opinions, increase the net assets index to suspend the listing, and stipulate that the listing will be terminated if the net assets are negative for three consecutive years.
