Vice-presidents Emili Rousaud and Enrique Tombas sent a letter on Thursday together with four other directors - Silvio Elias, Maria Teixidor, Josep Pont and Jordi Calsamiglia - revealing they had handed in their notice.
"At the proposal of the President, Josep Maria Bartomeu, the Board of Directors have approved the appointment of Jordi Moix, as Vice President for Economics and Equity; Pau Vilanova, as institutional vice president; Oriol Tomàs, as Vice President of the Commercial Area; Marta Plana, as Secretary of the Board of Directors; and David Bellver, as treasurer," Barca said in a statement on Monday.
"Javier Bordas will be the manager responsible for the football first team, while Xavier Vilajoana will be in charge of Barça B, the youth teams and women's football.
"The executives responsible for the Compliance Committee will be the Secretary of the Board, Marta Plana, and the treasurer, David Bellver, while Joan Bladé, in addition to continuing to be responsible for the basketball teams, will be responsible for the Control and Transparency Committee."
Barca also revealed they will be taking legal action against Rousaud after the former vice-president claimed on Friday that somebody had been stealing money from within at the Catalan club.
"In the face of grave and unfounded allegations made by Mr Emili Rousaud, the club's former Vice President, in a number of media interviews, the Board of Directors categorically denies any action that could be described as corruption and have agreed to bring the corresponding criminal action accordingly," the statement continued.
"FC Barcelona cannot tolerate allegations that seriously damage the institution's image. The criminal action to be taken is in defence of the honour of the club and its employees. The existence of an ongoing audit must put an end to this matter."
