Research On Goodwill Impairment Accounting Model Based On Improved Headroom Method

In 2018,45 A-share listed companies recognized more than 1 billion yuan of goodwill impairment loss,leading to a "big face change" in performance.Goodwill impairment "too little,too late" is one of the most important phenomena in the subsequent accounting results of goodwill.In response to this phenomenon,in December 2017,the IASB proposed to include "headroom" into the factors considered in goodwill impairment test,and to apply the headroom method to improve the current impairment test model.However,according to IASB's latest "business combination: disclosure,goodwill and impairment" discussion draft,the current headroom method cannot significantly improve the effectiveness of goodwill impairment test at a reasonable cost.In order to enable the company to recognize the impairment loss of goodwill in time and improve the effectiveness of goodwill impairment test,this paper adopts normative research method,case analysis method and comparative research method to improve the current headroom method,discusses the optimization method of goodwill impairment accounting mode of Listed Companies in China,and selects the case of Tangel culture goodwill impairment for application analysis.First of all,the paper introduces and analyzes the headroom method and the updated headroom method proposed by IASB in detail.On this basis,it puts forward the "improved headroom method",and deduces the goodwill impairment accounting process under the improved headroom method.Then,select the case of goodwill impairment of Tangel culture for case analysis,and compare the goodwill impairment test results of Tangel culture under the current impairment test method and the improved headroom method,and then analyze the optimization effect of the improved headroom method on the current goodwill impairment test.It is found that the improved headroom method can reduce the shielding effect of headroom on the impairment of goodwill,enable the company to recognize the impairment loss of goodwill in a more timely manner,and avoid the occurrence of "taking a bath";secondly,it can use the actual cash flow generated by the asset group after M & A to measure the value change of the asset group,and then judge the impairment of goodwill to avoid the situation that the impairment of goodwill can not be recognized in time due to the optimistic estimation of cash flow;thirdly,it can provide investors with information about whether the expected acquisition is realized,and effectively make the management responsible for the acquisition decision.At the same time,the application of the improved headroom method,on the basis of improving the disclosure of goodwill and its impairment information,will not significantly increase the cost of the company.In addition,when the goodwill is initially recognized,the identifiable intangible assets should be recognized as much as possible to avoid excessive goodwill and fundamentally reduce the risk of goodwill impairment.In this paper,based on the real business cases and the international research frontier,aiming at the existing problems of the current goodwill impairment test method,the author puts forward the goodwill impairment accounting model based on the improved headroom method,which improves the effectiveness of goodwill impairment test,provides a new idea for improving the goodwill impairment test method,and can also provide help for the future reform of goodwill accounting model,the improvement of goodwill information disclosure and the prevention and resolution of financial risks.
