Reporting on Gender Diversity - Walk or just Pinkwashing? (Seminar)
Dozent/in: Patrick Velte
Termin:
14-täglich | Mittwoch | 10:15 - 13:45 | 25.10.2023 - 24.01.2024 | C 6.321 Seminarraum | 22.11. entfällt
Inhalt: Introduction to the topic: Women are (still) underrepresented on the boards of German listed companies. In addition, women in management positions earn less on average than their male colleagues (gender pay gap). It is undisputed that this is an untenable state of affairs that contradicts the current understanding of sustainability of the company's divergent stakeholder groups. Despite recent regulatory interventions by national legislators (e.g. introduction of the women's quota in the supervisory board, Remuneration Transparency Act, planned women's quota in the executive board), regular reporting on gender diversity aspects at management level in current corporate practice is sluggish and in need of optimisation, despite theoretical evidence. It is becoming increasingly important to present concrete strategies for achieving gender equality in management in corporate governance and sustainability reporting. Since 1 January 2016, companies that are either listed or co-determined have had to set targets for increasing the proportion of women on supervisory boards, executive boards and at the highest management level. They must report publicly on these targets and their achievement in the corporate governance statement pursuant to section 289a (2) no. 4 HGB, either in the (group) management report or on the website. This affects approximately 3,500 companies in Germany. Since 01.01.2017, large public interest entities with more than 500 employees have to publish a non-financial statement. This statement must address, among other things, employee and social concerns and the concepts pursued in connection with them. Currently, the federal government is also planning a quota for the executive board for certain companies. In the future, at least 1 woman is to be appointed to a board of at least 4 persons. Since the financial crisis of 2008/09, many companies have voluntarily (for various reasons, especially stakeholder expectations) prepared sustainability reports according to national or international frameworks (e.g. the German Sustainability Code or the guidelines of the Global Reporting Initiative). According to the well-known "three-pillar concept" (triple bottom line), CSR reports are divided into the three areas of economic, ecological and social sustainability. According to the GRI G3 Reporting Guidelines, the latter concerns "[...] the impact of an organisation on the social system in which [it] operates." This includes not only a company's social commitment, but in particular its own labour practices and management approach. Based on this long experience with sustainability reporting and regulations, it can be assumed that (successfully) implemented measures for equality and the advancement of women constitute an essential component of diversity reporting. Here, readers should find information on how, for example, discrimination in the form of wage inequalities can be avoided or the proportion of women in management levels can be concretely increased in the near future. An extremely innovative approach, which is, however, limited to a few large corporations in Germany so far, involves integrated reporting according to the framework concept of the International Integrated Reporting Council (IIRC), which seeks a consistent linking of these "soft" performance indicators with the "hard" financial indicators. Within the framework of gender diversity reporting, companies can present both general concepts and concrete indicators, such as on gender-specific salary distribution, cases of harassment (and countermeasures taken) or the composition and interaction of governing bodies. Since the under-representation of women in management positions and the gender pay gap in large companies are a fact, it can be assumed that the concrete figures are also likely to be expandable in the sustainability reports of the individual companies. In this case, there is a risk of positive self-promotion from a marketing point of view that is not accepted by stakeholders. This can lead to a situation where, in addition to concrete reporting gaps due to competitive aspects (topic: protection of competition), attention is paid above all to superficially formulated statements of intent in the sense of a generally equality-oriented attitude of the management. From the point of view of the readers of the report, there is a danger that the contents of gender diversity reporting are formulated so vaguely that they could be used in other contexts and in later years without major changes (so-called boilerplates) and that companies present themselves as better than they are in terms of equality and the advancement of women. In reference to the well-known counterpart of greenwashing from environmental sustainability, we speak here of targeted pinkwashing behaviour on the part of management.

Inhalt: This lecture deals with key challenges in financial, sustainability, & integrated reporting from an (inter)national perspective. We will focus on a listed multinational corporation in Germany. First, a comparative analysis of financial reporting according to German Commercial Code (GCC) and International Financial Reporting Standards (IFRS) will be presented. Second, after a theoretical foundation and an overview of empirical research methods in financial reporting, the economic need of sustainability reporting and integrated reporting will be discussed. Current selective topics of empirical quantitative research will be prepared in groups for power point presentation and scientific papers (as structured literature reviews).
