Audit control is an integral part of supervisory procedures at any company.

Audits are necessary for gaining the trust of clients and partners as well as for managing the company. In this sustainability-oriented era, various stakeholders expect that non-financial information about businesses are collected, presented and validated in the same way as financial information.

Who is required to undergo an audit?

The requirement of preparation and public disclosure of sustainability report applies to all large companies, corporate groups and companies listed on regulated markets (except for publicly listed micro-enterprises). Data must be presented in conformity with the mandatory EU sustainability reporting standards and audited by an independent auditor. The sustainability report is presented as a separate part of the management report within the company’s annual report.
