隨著資本市場的多元發展,近年來台灣企業發行可轉換公司債之件數倍增,可轉換公司債之所以受到企業青睞,成為愈來愈受歡迎的籌資工具,必有它的獨特之處,而海外可轉換公司債也是公司擴張海外市場的一大助力。本論文的研究目的即在了解台灣上市上櫃公司以國內可轉換公司債(Convertible Bond;簡稱CB)或海外可轉換公司債(Euro Convertible Bond;簡稱ECB)進行融資對其財務績效之影響,並驗證台灣企業發行ECB是否支持Merton(1987)之投資者認可假說。
本論文以1999至2003年間,96家僅發行國內可轉換公司債、70家僅發行海外可轉換公司債、11家同時發行國內與海外可轉換公司債的公司為樣本,實證研究之主要結論如下:
1.公司發行CB或ECB後財務槓桿顯著上升,尤以CB為甚,顯示其財務
風險增加,降低公司財務彈性。若以市值衡量負債比率,則ECB發
行公司在發行前的負債比率較CB發行公司略高,但發行後二年顯著
下降較快。
2.僅發行CB或ECB之樣本公司發行後系統風險皆顯著上升,但同時發
行CB與ECB之樣本,在發行CB後系統風險顯著上升,發行ECB後系統
風險則無顯著變化。
3.在發行公司的績效表現方面,本論文以可轉換公司債發行後的α係
數變化情形為超額報酬之衡量指標,發現三組樣本結果皆顯示CB與
ECB發行後其股價績效表現不佳,前兩組樣本較為顯著。
4.以僅發行ECB組別的70家公司為樣本進行實證,結果顯示發行ECB確
實能增進公司之能見度;但在投資者認可假說方面,台灣市場ECB
的發行並不支持投資者認可假說。故雖然ECB的發行增加公司的能
見度,但財務彈性降低與系統風險增加可能使投資者對公司之未來
前景產生更高之不確定性。 / With diverse development and further integration among international capital markets, more and more companies in Taiwan tend to issue convertible bond for financing in the past few years. In addition, Euro Convertible Bond (ECB) also facilitates firms to expand overseas markets and becomes popular. This study not only focuses on risk and stock price performance changes around convertible bond offerings, but also compares the differences between CB and ECB on research topics. It takes issuing companies that listed in Taiwan Stock Exchange or OTC as objects of study. Moreover, the study tests firm visibility as well as Merton’s investor recognition hypothesis of ECB.
Picking 177 samples from Taiwan companies during 1999 and 2003, and I divide them into three groups. 96 firms in the first group only issue CB, 70 firms in the second group only issue ECB, and 11 firms in the final group issue both CB and ECB.
According to the empirical results, this study points out several conclusions as follows. First, financial leverage increases after issuing CB or ECB, especially CB firms show more significant increase, and it reduces financial flexibility. Second, systematic risk of companies which only issuing CB or ECB reveal significant increase. However, the 11 firms in the third group show systematic risk that measured with beta increases significantly following CB issuances, but doesn’t change evidently following ECB issuances.
Third, I would like to view stock price performance of CB and ECB issuers. The finding shows that relative long-term excess return of three groups all decrease, and the former two groups appear significant drop. Finally, Merton’s investor recognition hypothesis isn’t supported by 70 ECB samples even though issuing ECB could promote firm visibility. This outcome is probably attributed to decrease of financial flexibility and increase of systematic risk.
