Outline of Final Research Achievements

An extensive review of previous studies confirmed that the level of disclosure of goodwill and goodwill impairment information is used at the discretion of management in its disclosure strategy. On the other hand, it became clear that it is necessary to establish a highly valid method for measuring the disclosure score because the method for calculating the disclosure score for measuring the disclosure level differs depending on the research. In addition, the results of this study for Japanese companies show that the larger the amount of goodwill generated, the longer and more complex the explanation of the reasons for business combinations in the notes tends to be, and that although the length of the explanation of reasons has a positive impact on future business results up to a certain number of characters, the longer the text has, the more negative impact on future business results.
