究上將庫藏股宣告前之特定事件區分為現金增資及發行公司債券兩種，並比較這兩種事件後 宣告買回庫藏股之效果。本研究之資料來源為台灣經濟新報資料庫，共蒐集 2858 件庫藏股買 回事件，其中有 105 次庫藏股宣告之前一年亦宣告進行現金增資，而有 299 家次庫藏股宣告 前一年發行公司債。 本研究主要發現庫藏股宣告前企業之異常報酬為負值，而宣告後之異常報酬為正，顯 示庫藏股宣告對股價有正面的助益，尤其在宣告後的第一天更為明顯。而前一年先進行現金 增資，再宣告買回庫藏股的效果雖然有向上的趨勢，但是累積宣告效果始終為負值，亦即對 股價不會有正面的助益。而企業在前一年有發行公司債券者，則在第二年進行宣布買回庫藏 股之效果為正，顯示這樣的財務操作模式對於股價有正面的幫助。 關鍵字: 庫藏股，買回庫藏股 ，連續事 ii FCU e-Theses &

1.1 Background 1.1.1 Share repurchase Share repurchase programs have been increasingly popular over the last year and frequently observed One of the explanations for the increasing popularity of share repurchase behavior is the change in governance over the last years In Euro, Andriosopoulos and Lasfer (2015) indicated that announcement repurchase increases to 47.2 billion Euro in 1997 compared with 14.2 billion Euro in 1996 Previous researchers show that there are 1159 events of announcement repurchase from 1989 to 1997 in Canada (Ikenberry et al 2000) 264 events of buyback from 1985 to 1998 in British (Rau and Vermaelen 2002) Hatakeda and Isagawa (2004) sought that 452 events from 1995 to 1998 in Japan and 800 events from 1993 to 1997 in Hong Kong (Zhang 2005) The share repurchase will be completed mainly through open market transactions Brav et al (2005) found that share repurchases are now a more important form of payout compared to the past Besides, Barclay and Smith (1988) assumed that repurchase stock is an important financial strategy of the firm in developed countries Now that the economy is continuing its recovery, share buyback programs are quickly becoming all the rage once again with companies and investors When a company has excess cash at the end of the day, there are only a few things that it can with it They can save it for a rainy day, invest in new property and equipment for the business, acquire another company, retire debt, issue a one-t special stock to shareholders, or buy back share of their stock on the open market A “stock buyback program”, which can also be known as a “share repurchase program”, is when a company buys its share back from current shareholders through the open stock market Buyback programs can be seen as a signal that a company believes its shares are undervalued and is often viewed as an efficient way to put money back into its shareholders’ pockets According to Stephens and Weisbach (1998), there are three methods in which a firm can repurchase its own shares: tender-offer repurchases, Dutch auction repurchases and open-market repurchases Following McNally (1999) that an open market repurchase increases a firm’s stock price by increasing its return on equity and its earnings per share So, the open-market share repurchase is the most wellknown method The stock market reacted positively to the announcement of repurchase Many studies have investigated that when the firms announced repurchases, firms realize positive abnormal returns regardless of the time horizon Zhang (2005) found that the three1 FCU e-Theses & Dissertations (2018) The Announcement Effects of Share Repurchase based on the Prior Consecutive Events year buy and hold abnormal return, which is measured against a portfolio of control firms that are matched by size and book-to-market value ratios, is over 20% Chan et al (2004) argued that after share repurchase announcements, announcing firms experience an average buy-and-hold yearly return of 26.2% following the announcement date In addition, a significant increase in the price of the repurchases stock in the next year, implying that the market reacts slowly with the information of buyback in short-term Further, the long-term performance of the stock repurchase is positive About the reasons that why the firms buy back their stock A stock repurchase plan can be a good way for a business to reinvest in itself, by using any excess cash at its disposal to buy back shares of its own stock Dittmar (2000) gives several reasons a firm may repurchase stock The first, Excess capital hypothesis Repurchase stock, like paying stocks because in open market repurchases, the firms not have a commitment to repurchase (Dittmar 2000) and repurchase is a more flexible means of distributing capital since a penalty is incurred if distributions are subsequently reduced (Denis et al 1994) The second, Undervaluation hypothesis: Repurchase and Policy The repurchases stock is flexible in timing which is beneficial because firms can wait to repurchase until the stock price If the stock is undervalued, the firm may repurchase stock as a signal to the market or to invest in its own stock and acquire mispriced shares According to this hypothesis, the market interprets the action as an indication that the stock is undervalued (Dittmar 2000) The third, when the firms announced buy back their stock, there are no taxes paid by shareholders Open-markets repurchase stock, shareholders have the freedom to make their own decision when to pay taxes on their gain (Voss 2012) So, having several possible motives behind the companies announce buy back stock Voss (2012) gave motives: undervaluation, managerial incentives, and the relation between stock repurchase and stocks Dittmar (2000) found that firms repurchase stock to take advantage of potential undervaluation and in many periods, to distribute excess capital 1.1.2 Share repurchase announcement in Taiwan Share repurchases have a long history in the United States, and the research on that has been conducted in the early 1908s Since then, many research papers focused on US stock market There are also many papers focusing on other countries and districts like Canada and Europe These papers dig into the motives of share repurchase and show a large number of empirical results to prove the positive relationship between share repurchases and stock return or results to the positive of announcement repurchase stock In Taiwan, according to corporation law, share repurchase was regulated by articles 158, 163, and 167 FCU e-Theses & Dissertations (2018) The Announcement Effects of Share Repurchase based on the Prior Consecutive Events 2369 Lingsen Precision 20030826 20050117
