Spain is one of the European countries that is the most strongly committed to the presentation of non-financial information. In 2017, Spain adapted its legislation to Directive 2014/95/EU through Royal Decree-Law 18/2017, which required Public Interest Entities (PIEs) to provide information in accordance with the requirements of the European Union (EU) Directive, with respect to financial years from 1 January 2017. Our research is focused on Spanish IBEX-351 listed companies and seeks to identify current trends in non-financial reporting. To our knowledge, the present paper is the first study to examine the impact made in Spain by the legislative changes. Our aim is to analyse the publication of non-financial information by Spanish listed companies whose first reports in this regard were made from early 2018. Specifically, we consider the impact of this information disclosure, determining whether the companies in question restrict themselves to meeting regulatory requirements or whether they go further and voluntarily supply additional information. Our findings show that the level of regulatory compliance produced is associated with the business sector in which the company operates. We also show that the highest rates of disclosure of non-financial information correspond to companies that provide this information in the sustainability report.

Corporate social responsibility (CSR) has greatly influenced business communication. CSR reporting has become the main tool through which organisations worldwide communicate their economic, social and environmental performance. Just as this practice is consolidated, the need for credible information in this area is critical. As a result, some companies subject their CSR reports to an assurance process. Several studies have analysed CSR reporting and assurance among stock companies, but few authors have developed a non-stock firm perspective. Given the shortage of prior research, we analyse these practices, focusing on cooperative and mutual organisations because, as social enterprises, they have a special link with CSR, and they represent another kind of firm with different transaction costs. By combining statistical and content analysis methods, we aim to identify the determinants that influence the adoption of CSR reporting and assurance, the choice of assuror and the quality of assurance statements. The findings reveal that size is positively but non-linearly related to reporting, while country and sector significantly affect the adoption of reporting and assurance. Assurance statements substantially differ across providers and their quality depends on size, sector and assuror, exhibiting interactions between size and assuror and between sector and assuror.

Sustainability reporting and assurance have considerably increased in the last decades. Among different sectors, 'sensitive sectors' attracted the attention of many academics. However, most of research works were focused only on 'environmentally-sensitive sectors'. Therefore, after the loss of trust caused by the lack of transparency due to the crisis, 'socially-sensitive sectors' as financial services sector needs to strengthen users' confidence in the credibility of their reported activities. The aim of this paper is to assess assurance practices worldwide in one of the main 'socially-sensitive sectors': the financial services sector. We study what factors are associated with adoption of assurance and choice of assurance provider, and whether assurance statements differ across providers. Our results reveal that, compared to the global context, companies operating in the financial services sector are more likely to adopt assurance and to choose accountants as assurance providers. Our findings show that adoption of assurance depends on company size. We also found that companies using the financial services sector supplement are more prone to adopt assurance. Our results also evidence that choice of assurance provider depends on the country and listing status Finally, our research shows a great variability in assurance statements across providers.

Purpose This paper aims to investigate the relationship between corporate reporting on issues related to the Sustainable Development Goals (SDG) and the quality of non-financial information (NFI) corroborated by different types of assurors. Design/methodology/approach The study methods used include logistic regressions, focusing on data for Spanish listed companies in 2017–2018. Findings Analysis shows that companies are more likely to report SDG-related performance when their sustainability report is assured. This association remains constant irrespective of the nature of the assurance, which only became mandatory in Spain following the entry into force of Act 11/2018 in this respect. Moreover, companies that hire KPMG or PwC (two of the big four accounting firms) as assurance providers are more likely to report SDG-related performance than those that hire non-accounting firms. Finally, companies with higher quality assurance statements are more likely to address SDG-related matters. Research limitations/implications The authors believe the findings reported in this paper will help decision-makers better understand the quality of organisations’ contributions towards achieving the SDGs. Furthermore, this paper has implications for stakeholders, policymakers, academics and assurance providers concerning the relationship between SDG-related reporting and the quality of NFI. Originality/value To the best of the authors’ knowledge, no prior research has been undertaken to analyse the relationship between SDG-related company reporting and the assurance of NFI.

Sustainability Assurance (SA) is increasing worldwide. Cooperatives are highly susceptible to CSR but there is an interesting research gap regarding SA in them. We use mixed research methods (statistical and content analysis) to study SA practices of the top 300 cooperatives worldwide. Paradoxically, our results show scarce or late SA adoption, and country-level and sector sensibility do not affect SA adoption significantly. Conversely, country-level and sector sensibility influence the choice of the assurance provider. Finally, findings reveal that country-level and industry factors, and also the assurance provider, do affect assurance statements' quality.
