In this paper we empirically examine the effects of 451 restricted share repurchase announcements in Taiwan. Their 3-day cumulative abnormal returns are all significantly positive for different purposes and Tobin's qs. However, there is no significant difference in abnormal returns for different repurchasing purposes. This indicates that mandating a purpose is not really an effective tool for limiting managerial choice. Moreover, when the related variables are controlled, the other empirical results we conducted indicate that, at least in Taiwan, the traditional signaling hypothesis and the free cash flow hypothesis can function simultaneously to explain the effects of the restricted repurchase announcements.
