  • For joint audit fees not to exceed single audit fees, it is important that the share of one audit firm in the mandate is not too low in order to avoid the risk of free-riding and subsequently higher costs. Working on a leveled playing field, next to a balanced level of technology standards employed by both firms are minimum requisites for a cost efficient and high quality joint audit. 

Will joint audit create an additional burden on audited companies?

  • Not if the scope of the joint audit is well defined from the beginning to avoid any duplication of tasks.
