SYNOPSIS
This paper illustrates that, despite their general agreement on the decision-usefulness objective of general purpose financial reporting, the Accounting Standard Board of Japan (ASBJ) and the International Accounting Standards Board (IASB)'s conceptual frameworks are based on two different concepts of financial performance. By identifying and contrasting the two financial performance concepts and their impact on the rest of the frameworks and by explaining the thinking that underpins the ASBJ's chosen financial performance concept, it contributes to a debate about the role of financial performance concepts in fulfilling the decision-usefulness objective. Such a debate is pertinent to the revision of the IASB's Conceptual Framework, which is scheduled for completion in 2015.
