Reporting in terms of the principles of IAS 41, or equivalent, did not result in comparable financial results in the industry. This is mainly due to valuation challenges experienced and the significant costs of these valuations, contributing to the theoretical gap addressed in this study, where the cognitive theory was applied to determine how to improve the consistency, validity and reliability of the fair valuing of biological assets. The knowledge gap is a result of the inconsistent application of the requirements of IAS 41 which results in incomparable financial results which impairs the decision-making of the users of such information. The results of the study were analysed and contextualised to develop an application guideline to assist the financial statement compilers to present results to users that will enhance their decision-making. This guideline is the result of an investigation on the industry trend and standards on how to value, disclose and report on biological assets in the annual reports; an assessment of the valuation challenges experienced, the valuation factors considered and the frequency thereof; an analysis of the valuation inputs applied and a contextualisation of the various users’ expectations when these financial results are assessed. Such assessment included an inductive content analysis, further grounded theory contextualisation and grouping of the results into a guideline that was tested on various users to ensure the usefulness and validity thereof. The purpose of the study and the developed guideline is to determine how to improve the consistency, the validity and the reliability of the fair valuing of biological assets to derive at informing, comparable, decision-enhancing balances in a cost efficient manner when detailed information is presented. / Centre for Accounting Studies / D.
