Abstract

This paper examines the hypothesis that the timing of lockup expiration is crucial to earnings management (EM) behavior in the period after an initial public offering (IPO). Taiwan's unique two-stage lockup regulations make the Taiwanese sample an excellent candidate for examining this hypothesis. Three main results are reached. First, we find positive discretionary accruals (DAs) from the IPO quarter to the quarter after the expiration of the first-stage lockup. The DA in the quarter of the second-stage lockup expiration is significantly positive. The evidence shows that the lockup provision is key in the findings of significant EM in the IPO year and the following year. We also find a positive association between DAs in first-stage lockups and subsequent insider selling activity, indicating that insiders' selling after lockup expiration accounts for EM in the lockup period. Third, the extent of EM in first-stage lockup is negatively related to that around the IPO, consistent with the reversal nature of DAs.
