This study examines how the merger premium and payment method are influenced by the target’s earning quality in M&A’s events. The sample includes the M&A’s events in Taiwan from 1998 to 2009. We find the relation between target’s earning quality and merger premium are not significant. It implies that the bidders in Taiwan haven’t paid attention to the risk arisen from potentially poor earning quality. On the other hand, we document that bidders tend to employ cash as the payment method when earning quality of target firms is poor. This evidence is inconsistent to the foreign literature as well. The finding may be resulted from the observation that the target firms in Taiwan tend to be acquired when they experience inferior operating performance or financial distress. The need of cash then motivates the management of target firms prefers accepting cash as the payment method of M&A deal.
