Accounting changes and it has to be suitable to the worldwide economic and political condition of the market. In recent years, several amendments issued by the IASB substitute prior approaches. I document the changes carried out by the IASB on IFRS 3 and IFRS 11 in 2004 and 2008, focusing on the evolvement of the accounting of goodwill acquired in business combination. Along with the other information provided, this book finds evidence that the IASB has not always been completely independent and makes prospective hypothesis, through theories and an empirical study, that the most appropriate goodwill accounting treatment concerns a simplification of the current impairment-only approach.
