This paper critically reviews the main empirical research on goodwill accounting with the purpose of informing and contributing to current debates: the application of a systematic amortisation plus an impairment when required (amortisation model) or an annual impairment-only test (impairment model). Using the main databases (ABI inform, ProQuest Central, Emerald, Science Direct, Scopus and Google Scholar), this critical review highlights the difficulty to resolve doubts at this stage. Arguments for and against the amortisation and impairment models are found. Nevertheless, going back to a systematic amortisation does not seem to be the solution but the impairment test model is eliminated. We also note that there is more room for improvement of the impairment model. Thus, we provide some guidelines and recommendations to improve it. Finally, we find that further investigation can be carried out to fill the gaps identified in the literature and we make recommendations for future research projects.

This research is conducted for evaluating the impact levels of determinants affecting the differences of financial statements of FDI firms under Vietnamese Accounting (VA) and International Ac-counting (IAS/IFRS). Data were collected by conducting survey of FDI firms and audit firms for the period from 2015 to 2017. Based on the quantitative data, multiple regression was employed for showing the influence levels of determinants on the variable of differences of financial reports. The results show that seven determinants had positive relationships with the differences of financial statements prepared by FDI under Vietnamese accounting and IAS/IFRS. Based on the findings, some recommendations are given for reducing fee of conversion of financial statements from Vietnamese accounting to international accounting, increasing the comparability of financial statements and improving information quality of financial statements.
