The three, Trinh Van Nam, Pham Thi Thanh Nga and Chairman Le Ba Phuong were appointed at its general meeting of shareholders Tuesday afternoon.
This is the first time Phuong works at BOS Securities, though he was a member of FLC’s board of supervisors before resigning in 2014.
The BOS board used to have five members but two, Trinh Thi Thuy Nga and Huong Tran Kieu Dung, were arrested for allegedly manipulating the stock market in April and were officially dismissed Tuesday.
The rest, Le Ba Nguyen, Chu Tien Vuong and Nguyen Quynh Nga, all resigned in early August for personal reasons.
In July Nguyen was named chairman of FLC to replace Trinh Van Quyet, his brother-in-law who got arrested in March for allegedly manipulating the stock market.
BOS targets revenues of VND110 billion ($4.44 million) and profits of VND50 billion this year.
