近年來私募股權基金在全球興起一股廣泛的討論與重視，事實上，此類型的投資型態並非是近一兩年方產生出來，二次大戰後由麻省理工學院教授Karl Compton與哈佛大學商學院教授Georges F. Doriot與波士頓地區之企業領導人所成立之「美國研究與發展公司」(American Research and Development)可謂現代私募股權基金之濫觴。經歷多年發展，私募股權基金拜近年來全球低利率環境所賜，及亞洲等新興市場地區經濟起飛，開始全球大舉投資活動。 / 本研究主要以私募股權基金近十多年來在台灣的投資案為分析案源，進行其投資型態與交易作法之研究。私募股權基金在不同的交易型態中，扮演不同的角色及採行不同之交易作法。社會輿論常囿於單一個案之結果而對私募股權基金產生刻板印象。還原私募股權基金之真實面貌，是本研究之主要期許。

本研究以2007年「凱雷私募股權基金入主大眾銀行」一案當作研究主軸，以個案方式來呈現私募股權基金入主案的整個事件過程。大眾銀行財務體質不佳，急需資金，最終在眾多的籌資方式中選擇透過私募現金增資發行新股及可轉換公司債，引進單一策略投資人，轉換後外資持股比率最高大幅攀升至30%以上。 以事件研究法衡量股東財富的短期績效，研究發現在宣告日當天，市場對凱雷集團入主大眾銀行的訊息給予正面的回應，而自宣告日前10天至宣告日後8天，有顯著的平均累積異常報酬率。本研究亦衡量股東財富的長期績效，研究結果顯示， BHAR的衡量方法顯示，買進持有至第28個月及第36個月達10%之顯著水準，私募股權基金入主後有部份顯著增加股東財富。 凱雷集團透過持有多數股權，成為大眾銀行的最大股東，並進駐董事會，拿下半數董監席次，成功取得經營控制權，引進專業投資人的資金挹注來打銷呆帳及國際級的專業經驗、併購投資建議、改善公司治理等方式來強化金融業者的營運體質，使大眾銀行的信用評等得以被調升，有助於增加未來的融資彈性。本研究發現凱雷集團以增設獨立董事、縮小董事會規模及提高股權集中度來改善公司治理，與過去文獻研究結果一致，不過大眾銀行在經營效率性指標並未獲得改善。最後，分析大眾銀行入主前後3年經營績效的變化，研究發現凱雷集團入主後，大眾銀行在資本適足性、資產品質和獲利性指標等經營績效指標都有獲得顯著的改善。 / In this study, using the case of “Carlyle Group took over the Ta Chong Bank in 2007” to understand how did private equity funds implement. Due to the poor financial structure, Ta Chong Bank eventually selected through private placements to issuance the new shares and convertible bonds in a number of financing ways. Ta Chong Bank decided to find a single strategic investor, so the highest rate of foreign investor ownership after conversion could significantly increase to about 30%. To measure the shareholder’s wealth, this paper divided the short-term and long-term to analysis. First part, the capital market gave a positive response for the announcement of Carlyle Group took over the Ta Chong Bank. There was a significant average cumulative abnormal return between the ex-announcement and 8 days after announcement. In the long-term, the method of BHAR shows that buy-and-hold to 28 months and 36 months could get abnormal returns at 10% significant level. It presents that this case could increase the shareholder’s wealth in some specific periods. In this case, we find that Carlyle Group became the largest shareholder of Ta Chong Bank through acquiring majority equity. Moreover, Carlyle Group obtained the half numbers of directors, and successfully won the right of operational control. Through the international investment skills and professional operating experience, Carlyle Group improves corporate governance and financial structure of Ta Chong Bank and let the credit rating raised. This study also finds that Carlyle Group sets up independent directors, reduces board size and increases the concentration of ownership to improve corporate governance. It consists with the previous literature. But the operating efficiency indicator doesn’t improve so far. Finally, this study measures the change of operating performance. We find that just the operating performance indicators of capital adequacy, asset quality and profitability have improvement significantly.

過去文獻對於私募股權增資主要有三種論點，分別是資訊不對稱假說、監督效果假說以及管理者自我鞏固假說，過去研究基本上對於私募股權具有可以減輕資訊不對稱問題的效果有一致的結論，然而對於監督效果與管理者自我鞏固效果仍沒有一致的定論。因此本文控制了資訊不對稱、增資前的營運績效、公司股價表現以及發行規模等因素的影響後，從公司治理的角度去探討究竟國內的私募股權增資是符合監督效果假說，還是管理者自我鞏固假說。 實證結果顯示，董事會獨立性愈高、機構法人持股比率愈高時，愈傾向使用私募股權增資，隱含私募股權增資的確有提升對企業經理人之監督進而有助於公司價值之提升，符合(Wruck,1989)提出的監督效果假說。此外與過去研究發現一致，本研究的實證結果亦顯示，資訊不對稱愈高的公司使用私募股權增資的機率愈高，顯示企業可以透過私募股權增資來減輕資訊不對稱之問題。同時，若公司的股價在增資前異常攀升時，企業會傾向選擇公開募集增資，顯示出相較於私募股權增資，公募股權增資比較會有擇時之考量。當公司於增資前營運績效表現較差時會傾向選擇使用私募股權增資。而發行規模較小時，為了降低直接發行成本，企業會傾向選擇以私募的方式辦理增資。

近年來，市場低利率環境、證券市場之高報酬率吸引歐美私募基金業者蜂擁進入亞洲新興資本市場。在2001年時就有相關報告指出中國大陸已存在數千家私募基金，2009年「創業板」推出，幾十家由私募基金投資的企業相繼掛牌上市，私募基金在中國大陸的發展如火如茶。近年來因為其彈性之營運模式，已逐漸吸引全球資本市場之焦點。惟亞洲新興市場目前法律針對私募基金之相關規定，相較於歐美等發展較完備之資本市場，無論於私募基金之法律架構、私募基金之監理模式以及私募基金較常見之交易模式如公開收購、融資收購等，相關之法律規範仍尚待建立。 中國大陸對私募股權投資基金不論是中央各部會之間或是地方政府，近年來均分別推出多項法令，雖然有不少創新突破，但也有扞格及不足之處，本文針對中國大陸私募股權投資基金相關法規，探討私募股權投資基金的發展現狀及問題。 / According to the relevant report in 2001,there were thousands of Private Funds in Mainland China. In 2009, there were tens of Private Funds invested companies got public listed successfully due to the emerging of growth enterprise market. The development of private fund in China is getting quicker and more prosperous. However, in the contrary to the rapid growth in private fund markets, the government legislation in such fields is far away from effectiveness.

台新金控購併彰化銀行可以說是台灣金融業擬以融資購併方式進行合併的第一案，本研究希望透過分析此個案，了解台新金控購併的目的、資金來源與後續合併換股可能衍生之議題，為未來公股釋出，以及金融整併提供可行之方法。 本文就融資購併理論架構說明起，以當前台灣金融政策與購併環境現況分析，這包括實際已發生的金融購併案件及金融購併法規探討，它突顯出台灣在金融合併處理上是保守的。 / / The M&A of Taishin Holdings Cooperation (THC) and Chang Hwa Bank (CHB) could be regarded as the first M&A (Merge and Acquisition) by LBO ( Leverage Buy-out) in Taiwan. This study, by analyzing this case, discusses the purpose, the funding source of THC and the issues after shares-exchange, which indicates the feasible methods for the release of the state holdings and the combination of the financial institutes in the future. The beginning of this study discusses the theory and the structure of LBO to analyze the financial policy and M&A environment in Taiwan at present, including practical M&A cases and legal problems etc., which reveals not very aggressive. /

在中國大陸的法律環境中，外商私募股權基金是較新的議題，它同時牽涉了「外商投資」與「私募股權投資」兩個領域。因此，就外商私募股權基金而言，其為中國大陸在國外法律繼受嬗變後，再於法律雙軌制下的二次嬗變。 外商私募股權基金，是指由外國投資者注資或者外國投資者管理的私募股權基金。因此，它的市場屬性為「外國直接投資」、「國際金融服務」。 由於中國大陸對外商採取「外資法群」進行規範，而並沒有一部外商法典做集中、統一的規定。因此，彼此間存在一定程度的分散、重複、衝突等問題。再加上中國大陸對外商、內資採取雙軌制立法，故法律規範雖有創新但也常有彼此扞格或不足之處。也因此造成運作上的幾個問題：外匯管制、投資待遇、雙軌制、地方政府隨意的政策、實務操作的衝突(投資協議、有限合夥)、及優先股的欠缺。 財經法律因應經濟市場而生，惟經濟市場逐年改變。外商私募股權基金既是經濟市場的產物，就無法透過行政力量加以限制，也無需透過偏頗政策揠苗助長。僅需創造一個平等的法治環境，讓市場自行運作。 本文探討中國大陸對外商私募股權基金相關法規的發展現狀、投資障礙與內外資衝突等議題。除對如何完善立法略盡棉薄之力外，並希冀能提供台灣投資者於前進中國大陸時有所參考。 / In the legal environment of China, the foreign private equity fund is a relatively new issue, it involves two areas of "foreign investment" and "private equity investment” simultaneously. Therefore, with respect to the foreign private equity fund, it is subject to transmutation of foreign laws and subsequently the second transmutation under the dual system of laws in China. The foreign private equity funds refer to the private equity funds injected by foreign investors or managed by foreign investors. Therefore, its market attribute to the "foreign direct investment", "international financial service." Although China has adopted a series of laws to regulate foreign enterprises, there is not one foreign investment code as centralized and unified regulation. Thus, there exists a certain degree of dispersion, overlap, conflict problems among them. Along with the duel system of legislation adopted for foreign enterprises and domestic investments, there are often discrepancies or deficiencies between the legal requirements, although they have been innovated. This resulted in several operational problems: foreign exchange controls, investment treatments, duel system, arbitrary policies of local governments, conflict in practices (investment agreement, limited partnership), and the lack of preference shares. Financial laws are established in response to the market economy, but the economic market changes every year. Since the foreign private equity funds are the production of the market economy, they cannot be restricted only by the administrative power, and they don’t need partial polices to pull up. They only require creating an equal legal environment to make the market operate under its own mechanism. This paper discovers the issues with respect to the current development status of related regulations on the foreign private equity funds, foreign investment barriers and conflicts between domestic and foreign investment in China. In addition to make a little contribution to improve the legislation, it’s also expected to provide reference to Taiwan investors for developing business in China.
