This study examined the lobbying of the International Accounting Standards Board (IASB) by South African companies. The aim of this study was to establish the timing and methods of lobbying of the IASB by South African companies. Central to this study was the seminal work of Sutton (1984), predicting when and how companies lobby an accounting standard-setter. The research hypotheses for this study were formulated on the basis of Sutton’s (1984) predictions. The online questionnaire in this study was distributed to the top 100 JSE primary listed companies in order to collect primary data to test the four hypotheses regarding the timing, methods and perceived effectiveness of lobbying by South African companies. The findings of the empirical investigation indicated that most South African companies lobby later in the due process of the IASB and prefer using their auditors to support their views at the IASB. The findings are subject to certain limitations that are addressed in the study. Lastly, the researcher provided recommendations for future research in accounting standard-setting in South Africa. / Financial Accounting / M. Phil. (Accounting Sciences)
