Statutory audit in Slovakia is performed by statutory auditors or audit firms. Many of the audit firms are members of the globally operating audit networks. Membership in a network imposes certain rights and duties for audit firms. The existence and operation of the audit networks can be understood as one of the results of globalization that allows an increasing possibility of cooperation at the international level. Our goal is to clarify the state of audit firms operating in the audit networks. To achieve the goal, it was necessary to choose a purposeful work methodology and research methods, based primarily on the analysis of data from the list of the audit firms.
