Effect of mandatory pro forma earnings disclosure on the relation between CEO share bonuses and firm performance

This paper examines the effect of mandatory pro forma earnings disclosure on the alignment of CEO share bonuses and firm performance (i.e., annual stock returns). Using 6,583 executive-level observations from 986 non-financial firms in Taiwan over the period 1999–2004, we find a significant shift in the CEO share bonus pay-earnings relation caused by a marked reduction in bonus shares after the new disclosure rule becomes effective. The change in CEO compensation structure in turn leads to a closer link between CEO stock bonuses and annual stock returns. The result suggests that a more transparent earnings disclosure could positively affect board choices regarding compensation arrangements, thus inducing a better convergence of manager and shareholder interests.
