兩段迴歸結合蒙地卡羅模擬對可轉債定價之研究 / Pricing Convertible Bonds by Piecewise Regression and Monte Carlo Simulation

董恆元, Tung, Heng Yuan Unknown Date (has links)
可轉換公司債兼具了選擇權以及債券的性質,價值又會受到股價之影響,以傳統的方法定價十分不易。由於蒙地卡羅模擬能解決定價問題上狀態變數或許為多維度及路徑相依的問題,Kind 與Wilde 在2004 年提出以蒙地卡羅模擬對可轉債定價,且以最小平方迴歸法估計繼續持有價值,並在僅考慮轉換及還本兩種選擇權及沒有違約風險之下,以數值範例呈現單一迴歸模式無法適當估計繼續持有價值。然而,他們並未進行實證。本研究乃以民國99 年台灣發行的可轉債為研究對象,除考慮發行時的合約條件外,另加上信用評等的考量以將違約機率透過現金流量套入定價過程中,並分別以兩段迴歸及單一迴歸估計繼續持有價值以結合蒙地卡羅模擬,實證結果顯示就可轉債之起始定價的偏差比而言,兩段迴歸得到的結果優於單一迴歸。惟在兩段迴歸之下,超過八成的可轉債其模擬價格依然高於市場價格。實證結果也顯示價性(moneyness)及擔保狀況與定價的偏差有關。 / Convertible bonds (CBs) possess features of both bonds and options, and their prices are affected by the underlying stocks, which make the pricing problem an uneasy task for traditional methods. Since Monte Carlo simulation can handle the problems of path-dependence and multivariate dimensions faced by pricing, Kind and Wilde (2004) suggested to price CBs via least-squares Monte Carlo simulations (LSM), which estimate the continuation values by least squares regression. They also demonstrated that a single regression line could not appropriately estimate the continuation value even only conversion and redemption were allowed and the CB was free of default. So the idea of piecewise regression was recommended to improve the estimation process. However, they didn’t apply piecewise regression to real data. Therefore, piecewise regression together with Monte Carlo simulation were employed to investigate the pricing issue of Taiwan’s CBs. CBs issued on 2010 were selected, besides reviewing the contents of CB’s contracts, default risks based on credit ratings were taken into account to evaluate the discounted cash flows in the pricing procedure. Comparing the estimated model prices of LSM with initial selling prices, the mispricing rates of single regression model and piecewise regression model were obtained for further analysis. Result shows that the modified piecewise regression method performs better in mispricing rate. However, similar to previous findings, 80% of the estimated model prices based on piecewise regressions are still higher than market prices. It also shows that moneyness and guaranteed condition will relate to mispricing rate.

敵意併購下防禦措施之問題研究-以毒藥丸之規範為中心- / A study of hostile takeover defensive Tactics- Focusing on the regulations in poison pills

楊峻宇 Unknown Date (has links)
當併購行為未經目標公司之經營階層同意時,目標公司之經營階層,是否得採取對抗敵意併購之防禦措施?由於經營階層在採取防禦措施並成功排除敵意併購下,將產生確保自身經營權之效果。從而,防禦措施之採取恐有涉及其自身之利害關係,是否得以任意採取防禦措施即生疑義。再者,防禦措施之採用,涉及該項措施相關領域之基礎規範,包括法律及行政命令之範疇,此等規範之內容,亦有釐清之必要。此外,縱使符合防禦措施所涉及各該相關法律領域之基礎規範,針對於防禦措施之適用本身,是否可能發展出不同於基礎規範之內容,包括防禦措施所應有之適當程序與規制內容。本文試圖對此作等問題,整理相關學說及實務見解,並提出個人之淺見。 本文共分為七章,分別闡述題目所涉及之若干議題。第一章為「緒論」,說明研究之基本理念與架構。第二章為敵意併購之概說,首先本文先對敵意併購之意義作一界定與說明,其次介紹敵意併購之類型,包括所謂有害企業價值之相關敵意併購類型。再者說明敵意併購與防禦措施之關聯,董事會於敵意併購發生時,是否應具有中立之義務,亦或得基於保護全體股東之利益而積極採取防禦措施,值得加以說明。此外,本文將一一介紹常見防禦措施之內容,其類型包括預防性之防禦措施與臨時性之防禦措施,並分析此二類防禦措施區分之實益。 第三章為防禦措施之妥當性問題。敵意併購關於不同當事人間之利益狀態,包括經營者與股東間、收購者與目標公司股東間,以及目標公司股東與利害關係人間之利害狀態等,實影響法律對於防禦措施規範之立場,宜先予分析。其次,分別介紹英國、歐盟、美國、日本,以及我國法制上對防禦措施規範之處理態度。 最後,整理我國學者在立法論上之意見及提出本文之淺見。 第四章為防禦措施於我國法下之可行性。本文將一一分析,於第二章所介紹外國所常出現之防禦措施,於我國法制下適用之可行性,包括黃金股、多數表決權特別股、黃金降落傘、銀降落傘、錫降落傘、白馬侍從、期限利益或授權之喪失、改變公司資本結構、鯊魚驅逐、員工持股計畫、白馬騎士、小精靈防衛戰、支付綠色郵件之贖金、目標公司買回股份,以及阻止或延緩股東會之召開等防禦措施。此外,我國實務於經營權爭奪上常見之定暫時狀態假處分,其意義與法制規範之內容,本文亦作一介紹,並分析其適用於公司經營權爭奪之運作情況。 第五章為日本法上毒藥丸之適用。日本過去因其特殊之交叉持股結構,及股東對公司之忠誠度遠高於歐美之故,敵意併購之發展未如美國,然而近年來日本亦開始出現敵意併購,同時發展出日式毒藥丸之運用,實值得作為我國之參考。首先,本文介紹日本法上關於新股預約權之意義及其相關之規範。其次,日本近年來所發生之三件對抗敵意併購之案件,包括日本放送事件、ニレコ(NIRECO)事件以及ブルドックソース(BULL-DOG SAUCE)事件,本文亦將一一介紹其事實之經過,並分析日本法院之見解。 第六章為毒藥丸於我國防禦措施之適用。毒藥丸為防禦措施中,最為傳統且典型之防禦措施,毒藥丸於我國法下適用之可行性,值得詳加琢磨。首先本文介紹認股權所呈現之各種型態,包括員工認股權憑證、認股權憑證、附認股權特別股、附認股權公司債、可轉換公司債等,並說明其於我國法下之規範內容。其次再進一步分析此等認股權型態之內容於我國作為防禦措施之可行性。 第七章為本文之結論。本文試圖提出防禦措施之妥當規範所應有之適當程序與內容,並分析於我國法下之運用,以作為本文之結論。
