Abstract—The aim of this study is to gain more insights in
the disclosure practices among the largest public listed
companies in Nigeria, by examining the associations between
firm characteristics and the extent of voluntary segments
disclosure on IFRS 8 Operating Segments by using a sample of
76 companies. The results document that firm size and
industry type have positive association with voluntary
segments disclosure. In addition, negative association is
observed between firm listing age, growth, return on
investment, ownership diffusion and voluntary segments
disclosure.
