The Value Relevance of Negative Goodwill:An Empirical Study Based on the New Enterprise Accounting Standards

Based on the regulations on negative goodwill under new enterprise accounting standards,this paper explores the effects of negative goodwill on stock price and abnormal return using Residual Income Valuation Model and Return Model.The main conclusions are the following three aspects: First,residual income after deduction of negative goodwill has statistically significant positive explanatory power for stock price,while negative goodwill is negatively related with stock price;Second,unexpected earnings after deduction of negative goodwill has statistically significant positive explanatory power for abnormal return whereas negative goodwill is negatively related with abnormal return;Third,related robust tests also show that negative goodwill has no significant explanatory power for value.The above-mentioned empirical conclusions illustrate that not only the market can distinguish the earnings structure,but also the market investors can distinguish the value characteristics of negative goodwill.
