A group of former citigroup bankers urged the company's board of directors to cancel bonuses for hundreds of managers and reduce consultant expenses. According to a copy of a five-page letter sent to the board by this group this month, they requested the board to retract and stop distributing bonuses linked to the reform system and reshaping business lines to various management personnel of citigroup. According to sources familiar with the matter, the board of directors of citigroup has received the letter, and the group hopes to engage with the chairman of the compensation committee.
