PurposeConsequent on the widespread of fair value (FV) accounting with the coming into effect of International Financial Reporting Standard (IFRS) 13, this study investigated the post-implementation challenges of FV measurement from the perspective of auditors in Nigeria.Design/methodology/approachData collection was through a structured-questionnaire administered on auditors from diverse audit firm backgrounds in terms of size, international affiliation and global presence. Statistical techniques such as cluster analysis, factor analysis and ANOVA were applied to analyse data obtained from 277 respondents.FindingsIt was observed that the severest challenge of FV measurement bothers on the paucity of information for valuation of items. The magnitude of the challenges of applying FV measurement in various industry sectors appears similar. Although audit firm attributes affect perception on the challenges, there is concurrence among auditors that manipulation of values of assets/liabilities with no market price during estimation, leveraging on non-availability of market information on assets/liabilities by managers to manipulate financial statements, inappropriateness/non-compliance of valuation methods with IFRS 13, and low level of awareness among preparers of financial reports are notable post-implementation challenges of FV measurement.Practical implicationsConsidering that the adoption of IFRS 13 impliedly places responsibilities on countries applying the standard to develop institutional structures that facilitate the valuation of items using FV measurement, it seems the establishment of such apparatus may be a sine qua non for fully realising the socio-economic benefits of applying FV accounting.Originality/valueThe study contributes to knowledge by exposing the practical challenges of FV measurement and accounting estimates typical of a developing country that has fully implemented international accounting standards. Moreover, findings from this study could be compared with the result of investigations conducted in other jurisdictions to gain a deeper and wider insight into the challenges of FV measurement with a view to proffering solutions to the post-implementation challenges of IFRS 13.
