Audit services are defined as the standard audit work performed each year in order to issue an audit opinion on the parent company and consolidated financial statements of the Sonova Group as well as opinions on the local statutory financial  accounts or statements. Also included is extra work within the audit that can only be provided by the Sonova Group auditor, such as auditing of non-recurring transactions or the implementation of new accounting policies as well as consents and comfort letters in relation to regulatory filings.

Audit-related services consist of support to the audit such as providing advice on new accounting rules; this could be provided by sources other than the auditor who signs the audit report. 

Tax services consist of services in connection with compliance with tax laws.

Non-audit services mainly consisted of consulting fees in connection with local regulatory requirements.

The values of audit, audit-related, tax, and non-audit services are in line with ratios suggested by commonly applied good practice standards that relate to the independence of auditors. A formal policy issued by the Audit Committee is in place that regulates all nonaudit assignments of the auditors.

Informational instruments pertaining to the external audit

The external auditors report their findings semi-annually directly to the Audit Committee of the Board of Directors. In FY 2017/18, the external auditors attended 3 out of 4 Audit Committee meetings physically or by telephone conference. The Audit Committee of the Board of Directors reviews the performance, compensation, and independence of the external auditors on a regular basis. The Audit Committee reports its findings to the Board of Directors quarterly.
