Abstract Problem: The problem of this thesis involves the controversy that the implementation of poison pills generates. The conflict amongst various stakeholders that are affected directly or indirectly by the implementation of the poison pill also contributes significantly to the problem of this thesis. Purpose: The purpose of this thesis is to investigate and compare the benefits of the poison pill adoption on shareholder and management interests. We also seek to evaluate arguments for and against pill adoption, and determine if these arguments are valid in view of facts established from our study. Conclusions: Our study in this thesis has brought us to five conclusions about the poison pill policy in fulfillment of the purpose. We state in our conclusion that arguments for and against the poison pill can both be validated depending on the case, we also state that a general conclusion cannot be drawn as to the negative or positive effect of the poison pill on stakeholders. We proceed to argue that the pill is a very effective fighting toll in the current business world and state that more should be done to regulate pill implementation. We finish up our conclusion by identifying what appears to be an inverse relationship between management and shareholders benefits from the implementation of the pill. Originality: The uniqueness of our study resides in the theoretical framework that is developed from two prevailing hypotheses in the academic research of the poison pill. The previous studies either take on the management entrenchment hypothesis (MEH) or the shareholder interest hypothesis (SIH). However, we have combined the elements of both hypotheses and jointly revealed the advantages and disadvantages of the pill adoption for both management and shareholders via our original management shareholder benefits comparison matrix.

本研究以適用於民國九十九年九月一日修正前之「公開發行公司辦理私募有價證券應注意事項」辦理私募增資之上市櫃公司為研究對象，研究期間為民國九十四年十月十一日至九十九年八月三十一日，以探討內部人行為對私募折價幅度之影響。 　　研究結果發現，公司內部人若有參與私募者，則折價幅度會較純粹為外部人應募之私募案為大，顯示內部人可能藉由其職權，壓低私募價格以自肥，符合利益掠奪假說。此外，若內部人於應募前後，尚還有出售老股套利或隱瞞應募人與公司關係之情事者，其折價幅度越大。顯示內部人若意圖假私募手法圖利自身時，其確會運用其對公司之影響力，蓄意壓低私募價格以賺取折價之價差，或刻意隱瞞資訊以規避小股東之監督。因此，私募折價幅度與內部人是否參與應募以及續後之作為，確有密切關聯。 / This study examines the effect of insiders’ activities on the price discount of private placement. The sample period starts from October 11th, 2005 and ends August 31th, 2010, one day before the last revision on the regulation, Directions for Public Companies Conducting Private Placements of Securities. The empirical result shows that the price discount under private placement with insiders involved is more than that with outsiders only. The insiders, in accordance with entrenchment hypothesis, may benefit by discounting the price in the private placement. In addition, more price discount may also be taken by the insiders who intend to benefit from selling stocks while purchasing stocks from the private placement or intentionally concealing information about their relationship with the company. It’s evident that the price discount under private placement has something to do with whether the insiders are involved and how they behave in response.
