Chartered Auditor
PROVISION OF AUDIT SERVICES
According to Art. 2 let. a AOA, “audit services” are audits and confirmations that must be carried out by licensed audit experts or licensed auditors in accordance with federal regulations. In addition to the auditing of annual and consolidated financial statements, this also applies to selective auditing services such as audits of company formation, capital increases or mergers (see FAQ “Licensing requirements”). AbaFin Treuhand AG, based in Zug, was licensed as an audit expert under number 504739 and entered in the register of auditors. We ceased operations on October 15, 2025. Our extensive audit network includes professional partners whom we would be happy to recommend to you if required.

Limited Statutory Examination
Article 727 paragraph 1 number 2 CO stipulates that annual financial statements and, where applicable, consolidated financial statements must be audited if the companies concerned exceed two of three size criteria in two consecutive financial years. The thresholds 20-40-250 (balance sheet total - sales - full-time equivalents) apply to the audit of the annual financial statements for financial years beginning on or after January 1, 2012. An ordinary audit must be carried out if two of the three thresholds are exceeded in two consecutive financial years. With regard to the 2012 financial year, these are therefore the figures for the 2013 (reporting year) and 2012 (previous reporting year) financial years. If these criteria are not met, a limited audit can be carried out.
Valuation Reports by an Independent Expert
Valuations by an independent expert are required in a large number of cases: independent and objective valuations of businesses or assets. In the case of reorganizations (mergers, contributions in kind or demergers), independent valuations are used to determine exchange ratios or consideration. The appropriateness of the methods and parameters used must be critically examined. Martin Stäubli, certified auditor at AbaFin Treuhand AG in Zug, has relevant experience in this area.
