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 non-audit assignments of the auditors.
