The Impact of IFRS 8 on Segment Disclosure Practice: Panel Evidence from Italy

The study examines the effectiveness of IFRS 8, effective since 2009, in relation to both the magnitude of segment disclosures and the firms' characteristics that might affect the disaggregated disclosure policies decisions, on Italian listed companies during the period 2008-2012. The results show that on average, the new standard did not lead to relevant changes in the segment disclosures as previously stated under IAS 14R, thus demonstrating inconsistency with the expectations of the IASB. In addition, we demonstrated, by employing a fixed-effect regression, that the magnitude of segment disclosure is negatively associated with growth rate, size, profitability and ownership diffusion. The present study contributes to the extant literature in terms of the PIR review, discussing the effectiveness of IFRS 8 some years after adoption, and not merely considering the first year, where the results may be affected by the learning curve effect in countries less familiar with Anglo-Saxon accounting.
