The challenges and potential benefits of the external assurance of mandatory non-financial reporting. Evidence from Poland

Purpose: The paper analyses the challenges and potential benefits that stem from the relationship between an auditing firm and the companies engaged in mandatory sustainability reporting from the companyʼs point of view. Methodology/approach: Semi-structured interviews were conducted with a sample of Polish companies that engage in mandatory non-financial disclosure. Findings: The evidence collected through the interviews suggests that cooperation with an auditing company that goes beyond the minimum normative requirements brings benefits to the reporting company while also improving the non-financial reporting process, as well as the companyʼs awareness. This is particularly true for companies that started their non-financial reporting experience when it was not mandatory, as they were able to gradually adopt and grasp the related potential benefits. Research limitations/implications: A significant limitation is that the research was conducted on a small sample. To draw broader conclusions, the sample should be expanded to include additional companies. Originality/value: The paper provides empirical evidence on the relationship and cooperation between companies and auditors in the field of non-financial reporting, focusing on the conditions that enable the potential benefits of this relationship to materialize. Such relationships can be essential drivers that foster a sustainability culture within companies.
