The Research On Impairment Of Corporate Goodwill

China’s listed companies in recent years M & A activities are becoming more and more popular,in 2013-2018,A listed companies M & A activities are becoming more and more active and goodwill assets continue to grow,which makes the risk of goodwill impairment of listed companies significantly increased.Once the risk of goodwill impairment is triggered,it will cause immeasurable risks to the market as a whole,and bring difficulties to the operation of listed companies and seriously damage the interests of investors.For the early 2019 listed companies huge goodwill impairment phenomenon is common,to investors bring a profound lesson.The research on goodwill in our country is not perfect,the theory research and criterion of goodwill There are still shortcomings in normative research and practical operation research,especially in the study of the initial measurement and subsequent measurement of goodwill is particularly important.In order to reflect goodwill more accurately and truthfully,this paper makes in-depth research on the theories of goodwill.Because of the phenomenon of large amount of goodwill impairment in reality,this paper starts with the initial measurement of goodwill and the subsequent measurement,studies the problems existing in the initial measurement through the case of joint building photoelectric,and through the simulation of the initial measurement and evaluation process of goodwill.sensitivity analysis of the initial measurement was also studied.In the follow-up measurement research,we found that many listed companies did not disclose the necessary financial data,the use of impairment test method reasonable doubt and large goodwill impairment to bring serious negative impact on the company.To solve these problems,we discuss the improvement method of the current test method,and adopt the PAH method.The purpose of the PAH method is toExample reduce the "shielding effect" of the internal generated goodwill which is not recognized before the acquisition,to prevent the recognition of goodwill impairment after the acquisition is too little and too late,and to analyze the case of the PAH method,as well as to study and discuss the application of the PAH method to the building photoelectric case.In addition,the author also on the goodwill impairment and amortization method.This paper discusses how to improve the goodwill impairment test method,and provides a research for improving the goodwill initial measurement and subsequent measurement.This paper finds that in the existing initial valuation,most enterprises will overestimate the growth rate,underestimate the discount rate and lead to overestimation of the initial estimate of goodwill,which will greatly improve the risk of impairment of goodwill in the future.In the subsequent measurement,the goodwill impairment test method is too high in the initial measurement of goodwill,the scale of goodwill is too large,and the subsequent impairment risk is also increased.There are still shortcomings in the current accounting standards,enterprises do not fully disclose goodwill impairment information,resulting in asymmetric information,and the process of goodwill impairment has a strong artificial subjectivity,goodwill impairment lack of rationality and other phenomena.This paper proposes to improve the current measurement method of goodwill impairment from the following four aspects First,the initial recognition of goodwill should be more cautious;second,improve the subsequent measurement of goodwill,suggest the use of the PAH method or the use of goodwill impairment method and amortization method combined;third,establish and improve the information disclosure system and strengthen supervision;fourth,enhance the synergy effect to avoid and reduce the risk of goodwill impairment.
