摘要

2020年,新型冠状病毒病(COVID-19)成为全球关注的焦点。在本文中,我们研究了2020年第一季度企业对COVID-19的披露情况,这一时期企业面临巨大的不确定性,在披露什么和如何披露方面几乎没有指导。我们将SEC文件和收益电话会议中与冠状病毒相关的披露与疾病传播的时间表以及谷歌搜索和新闻文章中的信息收集和传播活动进行了比较。我们发现,公司初始披露受信息需求驱动,公司管理者主动向投资者提供信息。我们的主题建模分析表明,尽管企业认识到疫情对其业务的巨大影响,但它们在美国证券交易委员会(SEC)文件中的披露是笼统的,缺乏细节。最后,我们发现,在电话会议的问答环节,分析师积极主动地提出有关COVID-19影响的问题,随着疫情的发展,公司经理们在演示环节迅速提供必要的信息。

Talk about the Coronavirus Pandemic: Initial Evidence from Corporate Disclosures
The novel Coronavirus disease (COVID-19) has become the world’s center of attention in 2020. In this paper, we examine firm disclosures of COVID-19 during the first quarter of 2020, a time when firms face tremendous uncertainty and have little guidance on what and how to disclose. We compare Coronavirus-related disclosures in SEC filings and earnings conference calls with the timeline of the spread of the disease and with information gathering and disseminating activities in Google searches and news articles. We find that initial corporate disclosures are driven by information demand, and firm managers are proactive in providing information to investors. Our topic modelling analysis shows that although firms recognize the massive impact of the pandemic on their operations, their disclosures in SEC filings are general and lack specifics. Finally, we find that analysts are proactive in raising questions regarding the impact of COVID-19 during the Q&A session of the conference calls, and that firm managers are quick to provide necessary disclosures in the presentation session as the pandemic develops.
