As the number of M&A cases keeps increasing; however, it doesn’t enhance the rate of success at the same pace. Over the past 75 years, more than half of M&A cases didn’t reach the expected synergy; thus, how to find key success factors of an M&A case becomes more important. This study investigates the effect of merger premium and payment method on post-merger performance of 385 non-financial industry merger cases completed during 2000 to 2006. Furthermore, this study divides the full sample by method of payment and utilizes growth rate in equity market value 2 years after the merger activity as indicator of merger synergy. Other potential factors of success are regressed on merger synergy and the empirical results are as follows:.The merger premium reflects the extent of confidence that the acquiring firm has in realizing expected post-merger performance in the future and has significantly positive effect on merger synergy..The method of payment reveals how much information the acquiring firm has, and in most of the cases, M&A by cash payment outperforms in post-merger performance than those by stock payment. .For cash mergers, the debt ratio and prior performance of acquiring firms have significantly negative effect on post-merger performance..For stock mergers, prior performance of acquiring firms has significantly negative effect on post-merger performance but there is a significantly positive relation between the relative control of acquiring firms and post-merger performance .第一章 緒論 1 第一節 研究背景與動機 1 第二節 研究問題與目的 2 第三節 研究架構 3二章 文獻探討 5 第一節 併購之類型 5 第二節 併購之理論 8 第三節 支付方式簡介及相關假說 12 第四節 相關文獻探討 19三章 研究方法 24 第一節 實證模型 24 第二節 研究變數定義 25 第三節 研究資料 28 四章 實證結果與分析 30 第一節 敘述統計分析 30 第二節 迴歸分析 33五章 結論與建議 43 第一節 研究結論 43 第二節 研究限制與建議 46考文獻 48application/pdf504241 bytesapplication/pdfen-US併購溢價比例支付方式Mergers and Acquisitions (M&A)PremiumThe Method of Payment.http://ntur.lib.ntu.edu.tw/bitstream/246246/180012/1/ntu-98-R96722001-1.pdf
