However, there is no consensus between IAS and FASB on the choice of policy for segment reporting. Based on the analysis of IAS and FASB＇s statements for segment reporting, this paper points out that industry and geography are the two vital bases for determining the segments, and internal organizational structure also should be taken into account. Before segment reporting, a primary segment needs to be identified, and others can be regarded as secondary segments. The information of the segments can be disclosed in the form of supporting statement. This paper also gives a concrete format of segment reporting.展开更多
