Voluntary disclosure of intellectual capital items in roadshows and investor conferences: An empirical analysis of DAX30-companies

We analyze firms' voluntary disclosure of intellectual capital in a setting of presentations to analysts and investors. Firms use presentations to analysts and investors as an additional means of reporting. Due to lesser restrictions of this kind of reporting and also due to the private channel disclosure setting of such presentations, firms are able to highlight certain issues which they think to be important for interpretation and forecasting of firm success. In such a setting we can assess the benefit-cost relation underlying these disclosure decisions. The sample consists of German DAX30 firms, which are analyzed for the years 2001, 2003, 2005, and 2007, resulting in a total of 271 observations. We calculate quantitative and qualitative disclosure indices and also analyze whether time, industry and type of presentation influence intellectual capital disclosure. Findings show that customer capital, human capital, and process capital are reported more often than other intellectual capital categories. Industry and type of presentation are strongly related to disclosure indices. There is also a weak significant relation between time and disclosure index. Overall, firms tend to prefer qualitative voluntary disclosure of intellectual capital and only carefully disclose quantitative data. This suggests that the benefit-cost relation of quantitative reporting is negative. © 2010 Springer-Verlag.
