Research on Earnings Management Behavior Identification and Motivation of Goodwill Impairment—Taking Century Huatong as an Example

The formation of huge goodwill provides a good "cover" for enterprise management to carry out earnings management. Listed companies can create a huge amount of goodwill with the help of high premium mergers and acquisitions, and in order to achieve the goal of positive earnings management, they may intentionally choose to delay the provision of goodwill impairment. On the other hand, goodwill impairment may also become a means for management to carry out negative earnings management, especially in the case of poor short-term business performance and decline in performance, but the overall sustainable profitability has not been changed. Therefore, it is necessary to adopt appropriate methods and models to determine whether an enterprise has earnings management behavior under different circumstances ^[1]. Based on this, through the in-depth analysis of the relevant financial data of Century Huatong Company, the accrual profit separation method is used to identify the degree of earnings management, and the obvious earnings management motivation is revealed in the formation of goodwill and the timing of goodwill accrual.
