In the author＇s opinion, this provision has some conflicts with the accounting information quality requirements which require reliability, relevance, comparability, and caution. This paper mainly analyzes the contradictions by comparing the provision with the requirements and putting forward relevant solutions. In the end, this paper has drawn the conclusion that the loss of the long-term asset impairment shall be allowed to switch back with certain conditions.展开更多
