The purpose of this paper is to compare the segment reporting disclosures under SFAS No. 131 with those reported the previous year under SFAS No. 14. It is found that the change in segment reporting requirements under SFAS No. 131 has made a relatively significant impact on the disclosure of segment information. Over 2/3 of the sample firms have redefined their primary operating segments upon adopting SFAS No. 131. There has also been an increase in the number of firms providing segment disclosures and companies are disclosing more items for each operating segment. For enterprise-wide disclosures, the proportion of country-level geographic segment disclosures has increased, while the proportion of broader geographic area segment disclosures has decreased. However, the number of firms reporting earnings by geographic area has declined greatly as this item is no longer required to be disclosed for firms reporting on a basis other than geographic area.
