In a globalized world where representation and democratic values are extolled, especially in the West, institutions that do not profess and practice them are criticized for lacking legitimacy. The International Accounting Standards Board (IASB), as a social institution, influences and is influenced by the social environment. However, criticism has been leveled at the institution regarding its legitimacy, especially because it is a private regulatory entity. Such criticism calls into question values such as independence, public interest, due process, accountability, diversity, and representativeness. The objective of this paper is to analyze, based on some documents published by the IASB, the values that this institution professes, seeking to confer the perception of legitimacy before the public. The theoretical premise adopted is that of social constructivism and institutional accounting theory, which advocate that meanings and symbols are social constructions and that, therefore, institutions play an important role in the creation, maintenance, or modification of symbolic universes, as well as in their legitimacy. Discourse Analysis (DA) will be used as an instrument capable of revealing the values advocated by the IASB. In the end, it is found that the IASB has professed values such as representativeness, diversity, transparency, due process, public interest, independence, and accountability, seeking to legitimize itself before the public. In this sense, this article contributes to highlighting that the IASB's discourse is in tune with social values dear to the Western world.
