The General Meeting authorizes the BOD to determine the criteria and list of investors participating in the purchase of shares.
§     When selling the number of remaining shares to other investors (selected by the BOD), the BOD must ensure that the ownership ratio of that investor after distribution will not reach or exceed the ownership ratios as prescribed in Clause 1, Article 35 of the Law on Securities.
§     In case the undistributed shares are sold by the BOD to investors as prescribed in Point a and Point b, Clause 3, Article 42 of Decree No. 155/2020/ND-CP dated December 31, 2020, the BOD will hold a general meeting to approve the Resolution of the General Meeting before selling.
