In recent years, the complexity of the business world has led to the growing demand of organizations to provide information not only on their financial performance, but also on the business model, strategy, corporate governance, and contribution to sustainability. Non-financial reporting can be a way to meet the growing need for information about the business model and value creation process from the perspective of different stakeholders. Despite the development of innovative approaches to strengthen accountability and quality of non-financial reporting disclosures, stakeholders are demanding more objective and unambiguous data. Therefore, providing comparable information on the company's business model and value creation process can establish trust in the communication with stakeholders, making the non-financial information more reliable. The subject of the monograph concerns the quality and usefulness of the business model disclosures presented in corporate reporting, as well as highlighting the best practices that have been employed so far in the business model reporting. To date, comprehensive research on this issue within the literature is lacking. Hence, the study on companies' business model disclosures in non-financial reports seems to be of key importance. The book presents the results of the authors' own research on the practice of disclosures in non-financial reporting between 2015 and 2022 and the quality and usefulness of information on business models. This is an important source of knowledge addressed to those interested in non-financial reporting, including academics, companies, and practitioners such as controllers and accountants. It complements the current state of research in this area and recognizes the practice of business model reporting, in particular the quality, usefulness, and best practices of the disclosures.
