Emphasis on Pro Forma versus GAAP Earnings in Quarterly Press Releases: Determinants, SEC Intervention, and Market Reactions
研究公司季度新闻稿中强调备考利润还是GAAP利润的决定因素，发现2002年SEC干预后强调转向GAAP，且强调程度影响市场对盈余意外的反应。
Earnings press releases provide managers a forum to present their firm's quarterly financial information and perhaps influence perceptions of the firm's stakeholders. We explore the use of managerial emphasis as a disclosure tool and contribute to the debate over pro forma earnings. We examine (1) the determinants of emphasis placed on pro forma and GAAP earnings within quarterly earnings press releases, (2) whether there has been a shift away from emphasizing pro forma earnings toward GAAP earnings, and (3) whether stock market reactions to earnings news were influenced by emphasis placed on metrics within the press release. We find that firms emphasize metrics that are more value-relevant and portray more favorable firm performance. We also find that the extent of a firm's media coverage affects managers' emphasis decisions. Further, our results indicate a highly significant shift toward GAAP emphasis and away from pro forma emphasis in 2002 relative to 2001. Finally, our stock market tests suggest that greater emphasis on an earnings metric results in a stronger market reaction to the surprise in that metric. Overall, these findings are consistent with managers using emphasis in the earnings press release as a disclosure tool and this emphasis influencing at least one important stakeholder group—investors.
