Perhaps laws and regulations are not clear about this, but it can be understood that listed companies have actually fulfilled their information disclosure obligations by issuing announcements of resolutions of the board of directors, and the matters that need to be fulfilled are generally important (or enough to affect investors' decisions and the trading prices of their stocks and derivatives), and such important matters must be passed by resolutions of the board of directors. Therefore, listed companies fulfill their information disclosure obligations by issuing announcements of resolutions of the board of directors.
Not all board resolutions need to be announced. In quarterly reports and semi-annual reports, the matters considered by the board of directors are only quarterly reports or semi-annual reports, and there is no objection or waiver. It is not necessary to announce the resolutions of the board of directors, but only the summary and full text of the quarterly reports or semi-annual reports. I hope you understand.
