Quality and quantity of FTSE-100 segmental information reporting

Purpose - This study aims to explore the impact of international financial reporting standard no. 8 (IFRS 8) on segmental information reporting (SIR) after the post-implementation review (PIR) issued by international accounting standards board (IASB). This impact is examined in relation to quality and quantity as SIR dimensions represent, respectively, the level of reported items and segments. As a complement to this, the chief operating decision maker (CODM) identity is considered to understand the patterns of SIR dimensions. Design/methodology/approach - The SIR of the UK financial times stock exchange 100 (FTSE-100) listed companies over the period 2013-2016 is the research’s scope. Several criteria were developed to ensure a representative research sample. A disclosure index approach was used facilitating the use of content analysis for data collection, which pertained to the dimensions of SIR published by the FTSE-100 following IFRS 8 PIR. Findings - The IFRS 8 PIR has had several implications shaping the growing trend that is underpinned by the SIR dimensions published by FTSE-100 companies. First, the SIR quantity dimension positively corresponds over 2013-2016, but it still does not meet IASB’s demands. This, secondly, also applies to the quality dimension of SIR to uncover inconsistency with the existing knowledge being held regarding the introduction of IFRS 8. More specifically, the response of the FTSE-100 to mandatory and voluntary items seems to be in transition of substitution. Third, CODM’s identity was an insightful dimension in rationalising the understanding through the aforementioned dimensions. It is undertaken by boards of directors or executive committees and the case of the latter is associated with more disclose in relation to the CODM’s identity. Practical implications - These findings reveal implications to: academics undertaking further research about IFRS 8 PIR to challenge or endorse this conclusion, using similar or alternative approaches; the stakeholders’ decision-making process; and policymakers to re-think the structure of mandatory and voluntary items. Originality/value - This paper provides empirical evidence on the quality and quantity of SIR published by FTSE-100 companies following IFRS 8 PIR.
