Reporting profile


Sonova reports in an annual cycle: the most recent previous Annual Report and Corporate Social Responsibility Report were released on May 18, 2016. The 2016/17 reporting period covers the financial year from April 1, 2016 to March 31, 2017.

The Sonova CSR Report for 2016/17, when combined with the Annual Report for 2016/17, complies with the G4 Guidelines of the Global Reporting Initiative (GRI) and forms an integral part of Sonova’s UN Global Compact Communication on Progress. See our GRI Content index for details on how the report content maps against the UNGC principles. The index refers to the content of the online CSR Report. Additional relevant information about economic performance and remuneration is provided in the Compensation Report, Governance Report, and Financial Review chapters of the Annual Report.


The information and data provided relate to the entire Sonova Holding AG Group, including its group companies, unless explicitly noted. Some environmental data are limited to those Sonova Group companies that operate as headquarters, manufacturing sites, or wholesale distributors; group companies restricted to retail activities are, by necessity, partly excluded. Whenever applicable, the exclusion of these group companies is stated in the respective sections.

Restatements and significant changes

In September 2016, Sonova acquired AudioNova and notably expanded its hearing aid retail service networks in Europe. More details about the organization changes during the 2016/17 financial year are reported in the Annual Report. There were no significant changes during 2015/16 in the scope, boundary, or measurement methods applied in the report. Nothing significant has arisen during 2016/17 that would require a restatement of information provided in earlier Sonova CSR Reports.

Declaration and assurance

The report has successfully completed review by the GRI Materiality Disclosures Service on the ‘in accordance’ option ‘core’. External assurance for the 2016/17 CSR Report has not been conducted, due to cost-benefit considerations.

The compensation report, the consolidated financial statement, and the financial statement of Sonova Holding AG in the 2016/17 Annual Report have been audited by a statutory external auditor.
