• Panthera Inc is a Toronto-based producer of sports apparel, comparable in size to leading multinationals in the industry, such as Nike or Adidas. Challenged by several external stakeholders, Panthera Inc has to reconsider the materiality of information for several aspects of its financial and non-financial performance and align its disclosure strategy accordingly. The case is modular in structure and designed for use by accounting faculties. Part I requires to evaluate the materiality of several notes to the financial statements according to IFRS. In Part II, the company faces external pressure to introduce sustainability reporting, leading it to conduct a materiality analysis according to GRI. Part III sees the management considering the future reporting strategy of Panthera Inc, with Integrated Reporting in line with the IIRC being one possible option. Thus, throughout the case, students are confronted with materiality definitions from different reporting practices and the opportunity to practice their application.
