Accounting Earnings Announcements and Differential Predisclosure Information

Recent studies have detected an inverse association between a firm's size and the stock price reaction to the firm's accounting earnings announcements, which has been interpreted as evidence that larger firms have relatively richer information sets. This study expands on this work, using two firm-specific factors to capture both the time and flow-per-period elements of information production (period of listing and firm size respectively) and examines whether these variables are a better information proxy than is size alone. After controlling for firm size, a statistically significant inverse relationship between a firm's period of listing and the information content of its annual earnings announcement is detected. The findings have implications for standard-setters as well as for auditors'assessment of the risk associated with audits of newly listed firms.
