SEC reviews and earnings quality at IPO
研究了美国证券交易委员会对IPO公司S-1注册文件的审核是否敏感于盈余管理，发现审核能有效识别应计项目盈余管理，但对销售操控的实质盈余管理不敏感，且《创业企业扶助法》实施后盈余质量下降。
Purpose We aim to examine the sensitivity of Securities and Exchange Commission (SEC) reviews to financial reporting quality in S-1 registration filings of firms conducting Initial Public Offerings (IPOs) in the USA. The investigation is important as market participants rely on this information to make formative investment decisions, while there are well-known incentives for IPO firms to disclose earnings opportunistically. Design/methodology/approach Using a sample of US IPO filings on NYSE, NASDAQ and AMEX, we initially conduct a manual content analysis of themes covered in a training sample of comments from initial comment letters; then a Naïve Bayes machine learning algorithm is employed to expand the coding to the full sample. In testing the hypotheses, a series of negative binomial regression models are developed to examine the relationship between SEC S-1 reviews and earnings management. Findings We show that IPO firms with greater accruals-based earnings management tend to experience more extensive SEC reviews, suggesting they are effective in addressing poor accrual quality. Weak evidence on the effectiveness of the SEC review in addressing discretionary-expense-based real earnings management (REM) is identified. These associations have strengthened under the Jumpstart Our Business Startups (JOBS) Act. On the contrary, SEC reviews are insensitive to sales-based REM, particularly under the JOBS Act. Overall, our study sheds new light on the sensitivity of SEC reviews to earnings management, identifying some areas for further scrutiny. Originality/value We incrementally add to the literature by demonstrating the SEC are effective in detecting income-increasing earnings management through accruals-based and, to some extent, discretionary-expenses-based manipulations by IPO firms when preparing their registration statements. Further, to the best of the authors’ knowledge, this study is the first to identify that SEC reviews appear not to effectively target real earnings management via sales manipulation by IPO firms. We also document an increased risk of earnings management following JOBS, a finding that should be of interest to investors and policymakers, as it implies that the quality of earnings information has deteriorated under the JOBS Act.
