企業併購的成敗，基本上應視其併購的策略性目標是否達成，然而策略性的目標往往只能從收購後整體的營運績效或投資收益來進行評估。事實上，企業併購即是一種投資活動，投資後的環境變化事先即難以掌握，如何有效的預防企業併購的風險問題，尤為進行併購規劃時重要的課題。本文嘗試以「代理問題」來解釋企業併購完成後的「雙方道德風險問題」，希望利用支付方式的財務規劃，有效的對企業併購完成後的道德風險作防範。 本文的主要目的在於，利用訊息理論中的代理模型（principal-agent model），研究企業併購雙方在「資訊不對稱」下，利用「雙方道德風險模型」（double-sided moral hazard model）的建立，規劃最適的支付方式設計，並對模型最適支付方式契約特性與影響因素作分析。設定企業併購的買方公司（the bidder）為所有人角色，目標公司（the target）為代理人角色，並且雙方公司皆為「風險趨避」的態度，以期望效用極大作為決策依據。買方公司基於「風險分散(risk- sharing)」與「契約誘因(incentives)」的考量，設計一種最適的「簡單線性支付方式」契約型態，綜合部分現金與部分股票支付的「混合性支付方式」，進行併購投資的要約行動。 模型的結果，買方公司所提出的最適目標公司持股比例，為雙方的風險趨避係數、公司價值的變異風險，以及雙方努力投入的成本係數所決定。並且進一步求出最適的努力水準，與最適現金支付金額，設計最適的股票與現金支付比例，以作為企業併購支付方式財務規劃的建議。 分析最適支付契約的比較靜態結果。在其他條件不變之下，(1) 若買方公司風險趨避態度增加時，買方公司將提高目標公司持股比例的契約設計，增加契約誘因強度，以避免承擔過多企業併購的不確定風險；(2) 當公司價值估計變異風險增加（外在不確定風險增加），若買方公司的風險趨避係數大於目標公司的風險趨避係數時，買方公司將增加目標公司持股比例作為要約；(3) 若買方公司的努力成本增加時，買方公司愈不願意付出努力水準，傾向於提高誘因機制給目標公司增加目標公司的持股比例作要約。 修正訊息結構的假設，引入契約中加入「承諾付出一定努力」的條款，加入「買方承諾」條款時，雙方道德風險的最適契約設計可以簡化為單方道德風險模型。加入「雙方承諾」的條款時，模型則可簡化成以「完全訊息」沒有道德風險問題的方式來分析。比較三個方面的差異：(1) 誘因強度大小的比較：在單方道德風險下，最適目標公司持股比例契約，將大於雙方道德風險模型下設計的最適契約；雙方道德模型則需視彼此道德風險問題的抵換，誘因強度不一定大於完全訊息模型。(2) 比較靜態結果比較：就影響方向而言，風險趨避係數變動，對不同訊息設計影響方向皆相同；外生誤差風險變動時，單方道德風險的影響則確定為負；至於努力成本的影響方向則不變。就影響大小而言，雙方道德風險模型誘因強度敏感性則恆小於單方道德風險模型的影響；與完全訊息的敏感程度大小則不一定。(3) 雙方期望效用總和比較：在雙方道德風險模型下，最適契約符合契約雙方期望效用確定等值極大的條件。 修正風險趨避特性的假設，探討風險中立假設下，最適的簡單線性支付契約適用性的問題。可得在風險中立情況下，只有雙方道德風險模型，混合性支付方式線性契約的誘因機制仍存在。最後，利用「制度性的比較靜態分析」，歸納出企業併購雙方道德風險問題下，當外生變數變動時，「完全現金支付」與「混合性支付方式」的選擇取捨。

嘗試放棄傳統事件研究法 (event study)的固定系統 ，先針對股價的結構變化點作檢定，找出子區間的分到傳統的方法，根據系統風險改變的時點找出估計期窗口(-5, 5)中 AR、CAR 的變化情形，以測試資本市告之反應，並試圖找出其可能的影響因素。實證結果告對主併公司的股東財富雖然有正面影響(僅1.82﹪) ，但整個宣告窗口的累積效果似乎不大；而跨國購併之間的差異(國際效果)，除了購併宣告當日外顯然另外，水平型態的購併事件與產業的技術密集程度之宣告日後才顯現出來，至於支付方式對宣告效果所產國外的實證結果不符，而購併成功與否對主併公司之顯。

Denna uppsats är skriven inom området finansiering och behandlar fenomenet uppköp och företagsförvärv inom läkemedelsbranschen. I uppsatsen undersöker man läkemedelsbranschen och några nyckelaffärer utförda under de senaste fem åren. Syftet är att se om hypotesen om att det inte sker någon onormal överavkastning efter ett företagsförvärv eller sammanslagning till det köpande företaget gäller inom industrin. Modellen som används är ”the Arbitrage Pricing Model”, innehållande variablerna S&P 500, ^DRG, USA’s inflation och volymen av omsatta aktier på New York-börsen. Denna används för att beräkna en förväntad avkastning på aktien 48 månader efter affären. Ytterligare så används AMEX läkemedelsindex (^DRG) och Standard & Poor’s 500 (S&P 500) som måttstock för att jämföra utvecklingen av aktien under 48 månader efter affären. Hypotesen håller i tre av sex fall när indexen ^DRG och S&P 500 används som måttstock och i samtliga fall när den beräknade avkastningen används som måttstock. De beräknade estimaten visade sig vara aningen för optimistiska givet tidpunkten för affären. Marknaden hade vuxit mycket starkt under en lång tid och var på toppen just innan den föll kraftigt i början av år 2000. Inget av företagen nådde upp till de beräknade värdena. Inte heller lyckades de återhämta sig från det kraftiga fallet I marknaden till deras ursprungliga aktievärden. / This thesis is written within the field of finance and covers the Merger & Acquisition (M&A) phenomenon within the pharmaceutical industry. The purpose with this thesis is to examine the pharmaceutical industry and, with some key acquisitions done over the last five years, see if our hypothesis about no abnormal returns after an M&A to the buying firm, holds within the industry. The model used is the Arbitrage pricing model, incorporating the variables; S&P 500, ^DRG, US inflation and stock volume traded on NYSE, to calculate expected returns for a period of 48 months after the M&A’s. Furthermore we use AMEX pharmaceutical index (^DRG) and Standard & Poor 500 (S&P 500) as our base for measuring post-M&A performance 48 months after the M&A’s. The hypothesis holds three out of six times when using the indices ^DRG and S&P 500 as a benchmark and all of the times when using the calculated expected returns as benchmark. The calculated estimates turned out to be a bit too optimistic given the time of the M&A’s where the market had grown substantially over a long period and was at its peak just before it plummeted in the early 2000’s. Neither of the companies reached their estimated returns, nor did they manage to recover from the downfall to their initial stock value at the time of the merger.

Dans une perspective pratique et axée sur le droit transactionnel, l'auteur dresse un portrait global du régime juridique s'appliquant aux actionnaires minoritaires de sociétés par actions publiques canadiennes. Pour ce faire, il aborde, dans un premier temps, les divers mécanismes transactionnels utilisés par les sociétés désirant procéder à une opération de changement de contrôle. Dans un deuxième temps, il enchaîne en expliquant les enjeux entourant la protection des actionnaires minoritaires pour, par la suite, décrire les obligations afférentes au Règlement Q-27. Finalement, il propose une analyse du traitement des porteurs minoritaires à la lumière, d'une part, de la gouvernance d'entreprise et, d'autre part, de l'activisme des investisseurs institutionnels. / In a practical perspective based on transactionallaw, the author shows a global portrait of the legal regime applicable ta minority shareholders of Canadian publicly listed corporations. Firstly, he tackles the various transactional mechanisms used by corporations that want ta proceed ta a change of control operation. Secondly, he continues by explaining the issues surrounding the protection of minority shareholders. Then, he describes the obligations related ta Rule Q-27. Finally, he proposes an analysis of minority shareholders treatment in light of, on one hand, corporate governance and, on the other hand, institutional investors activism. / "Mémoire présenté à la Faculté des études supérieures en vue de l'obtention du grade de Maître en Droit (LL.M) Option Droit des Affaires"

In the lead up to the Year 2000 dot.com crash of publicly traded high-technology equities, Information Communication Technology (ICT) Companies proudly displayed inter-firm allegiances on their newly created websites. These collaborative relationships were in reality licensing agreements to develop or market new products internationally. Phenomena associated with ICT product development - collaboration, innovation, and internationalisation - are the core tenets of the accompanying dissertation. Leading scholars have suggested these phenomena challenge conventional economic theories of the firm. This study commences with tracing the evolution of trade and production theories from absolute advantage through to competitive advantage and introduces the concepts of non-adversarial collaborative advantage. Within the framework of the technology cycle, this dissertation then seeks to answer why firms engage in international collaborative innovation. The cycle of technological innovation is investigated and this leads to postulating a period of technological overlap and its implications for collaboration. One of the shortcomings acknowledged in the literature is the generic application of the term collaboration to cover a wide scope of inter-firm agreements. Within the literature this is referred to as a problem of multidimensionality. A model is developed in this dissertation that identifies the choices available to the firm and addresses the problem of defining collaboration. The choices provided in the developed model are more complex than simply choosing between external and internal intermediate markets. As a separable form of industry organisation, the success rates of alliance collaboration are compared to Mergers and Acquisitions (M&As) to validate issues of sustainability before examining the impact of location on innovation and collaboration. Again, theory is tested by recent events that require explanation. These events include the relocation of early stage foreign R&D to both developed and lesser-developed nations. The final chapter assesses the findings throughout this study and identifies separate and distinct roles for large and small firms in the international and collaborative commercialisation of new innovations. This central conclusion requires empirical validation and suggests the need investigate how firms shape the cycle of innovation from a reflected vantage point to the evolutionary perspective taken in this study. Further research is warranted because the literature on international innovation and collaboration is at an early stage and gaps in understanding remain.

Uma combinação de empresas ocorre quando duas ou mais empresas distintas se unem de uma única vez para formar uma nova entidade contábil. Dois métodos de contabilização das combinações de empresas são geralmente aceitos no mercado internacional - o Método de União de Participações (Pooling of Interests) e o Método de Compra (Purchase Method). Mas esses dois métodos não devem ser vistos como alternativas contábeis para uma mesma combinação. Para se determinar qual dos dois métodos deve ser utilizado em uma combinação é necessário que se analise a natureza da transação, se ela é uma compra ou uma união de interesses. Sob o Método de União de Participações (Pooling of Interests), os ativos e passivos das empresas combinantes são combinados na nova entidade pelos seus valores históricos. Pelo Método de Compra (Purchase Method), os ativos e passivos da empresa adquirida são combinados pelo fair value na nova entidade. Além desses métodos, mais dois métodos são usados, mas de forma menos freqüente - o Método Fresh-Start e o Método Push-Down Accounting. Pelo Método Fresh-Start, os ativos e passivos das empresas combinantes são combinados pelo fair value. Pelo Método Push-Down Accounting, os ativos e passivos da empresa adquirida são avaliados e contabilizados pelo fair value em sua contabilidade, para em seguida serem combinados na nova entidade. Este estudo tem por objetivo principal explorar os métodos utilizados no mercado internacional e principalmente norte-americano, a fim de combinar as Demonstrações Contábeis de empresas fusionadas ou incorporadas, e aplicar os métodos de União de Participações, de Compra e o Push-Down Accounting em um único caso hipotético, para se conhecer os seus reflexos nas Demonstrações Contábeis da entidade combinada. Na comparação aplicada dos três métodos, o Push-Down Accounting revelou-se como uma variante do Método de Compra (Purchase Method). O Método de União de Participações (Pooling of Interests) sugere uma completa comunhão dos interesses das empresas combinantes sem o reconhecimento de qualquer aumento da potencialidade de geração de benefícios futuros. Já o Método de Compra se assemelha a uma simples transação de compra que reconhece de forma objetiva, na data da combinação, o potencial mínimo de geração de benefícios futuros da empresa adquirida para a entidade combinada. / A business combination occurs when two or more companies merge at one single time to form a new accounting entity. Two accounting methods for business combinations are generally accepted in the international market - the Pooling of Interests Method and the Purchase Method. But these two methods should not be considered as accounting alternatives for the same combination. To determine which of the two methods should be used in a business combination the nature of the transaction should be analyzed, that is, whether it is a purchase or a pooling of interests.On the one hand, in accordance with the Pooling of Interests Method, the assets and liabilities of the combining companies are combined in the new entity making use of their historical value. In accordance with the Purchase Method, on the other hand, the purchased company\'s assets and liabilities are combined in the new entity making use of their fair value.Apart from these two methods, two other methods are used, even though less frequently - the Fresh-Start Method and the Push-Down Accounting Method. In accordance with the Fresh-Start Method, the combining companies\' assets and liabilities are combined making use of their fair value. In accordance with the Push-Down Accounting Method, the purchased company\'s assets and liabilities are first re-evaluated by its accounting making use of their fair value, in order to be subsequently combined in the new entity.The main objective of this study is an exploration of the methods used in the international and mainly North-American markets for combining the Financial Statements of merged or acquired companies, and an application of the Pooling of Interests, Purchase and Push-Down Accounting Methods to one single hypothetical case, in order to know its effects on the Combined Financial Statements. In the comparison of the three methods, the Push-Down Accounting Method proved to be a variant of the Purchase Method. The Pooling of Interests Method suggests a complete pooling of the combining companies\' interests, without recognizing any increase in the potential for generating future benefits. The Purchase Method in turn is similar to a simple purchase transaction which objectively recognizes, at the combination date, the minimum potential of the purchased company for generating future benefits for the combined entity.

文化常被認為是跨國併購失敗的重要原因，許多文化因素在研究與調查中仍屬薄弱。在本論文中，國家文化是衡量跨境併購文化差異的重點，我們使用了Hofstede 六維度來分析兩種家公司併購情況，即使聯想案例文化維度距離高於TCL案例，但聯想理解在最短時間內和解文化差異，聯想最終解決了問題並變成了利潤。研究表明，溝通是必要的，大大提高了併購的成功性，管理層在合併前，文化評估是必要決策收購的成敗的重要因素。 / The failure rate of cross-border M&As is still high and culture is often blamed for hampering performance. If substantial research has been devoted to investigating M&As performance, cultural factors remain largely unexplained. In this research, national culture is the focus to measure cultural differences in cross border M&As. we used Hofstede 5 dimensions to analyzes two cases, even though Lenovo case cultural dimension distance is higher than TCL case, but Lenovo understand reconciling cultural differences in the shortest time, Lenovo eventually solved the problems and turn into profit. The studies reveal that communication is a necessity, drastically improving the success of a merger, and a cultural assessment of both fit and potential are important factors for providing direction and guidance for necessary decision making and planning initiatives required by management throughout all stages of a merger or acquisition. The purpose of this conceptual paper is to highlight the tensions generated by national culture in cross-border M&As and Chinese enterprises want to increase the success rate of Cross-border M&As, they have to pay close attention on the cultural problems, make a good cultural assessment and manager the cultural integrating work in the cultural integrating process.

This dissertation explores the disclosure on intangibles acquired in Mergers & Acquisitos. The related empirical analyses are based on a sample of M&As that are accounted for under the International Financial Reporting Standards (IFRS) and United States Generally Accepted Accounting Principles (US-GAAP). In three different research papers I answer three distinct research questions. In order to enable capital providers and other external stakeholders to evaluate the PPA, the International Financial Reporting Standard 3 (IFRS 3) and the Statement of Financial Accounting Standards 141 (SFAS 141) require the acquirer firm’s management to disclose information about the assets acquired and liabilities assumed in the notes to the financial statement. The first research paper (see chapter II) addresses the following research question: Which information about intangibles acquired in M&As does the acquirer firm’s management disclose in the notes to the financial statement? The second research paper examines the factors that affect the initial recognition of goodwill. This research question is answered in the second research paper (see chapter III): Does the acquirer firm’s management opportunistically or efficiently use its discretion to recognize goodwill initially? The corporate information environment consists not only of corporate disclosure but also of disclosure by information intermediaries. The third research paper (see chapter IV) addresses this last set of research questions: Which information about intangibles acquired in M&As is provided in voluntary or mandatory corporate disclosures and in disclosures by information intermediaries? How are the disclosure channels interrelated?

We examine the impact of Mergers &amp; Acquisitions on credit- and investment risk using a sample of 402 acquisitions by 215 Swedish firms from 2000 to 2020. We find significant evidence that, on average, M&amp;A increases the credit risk and inversely decreases the investment risk of the acquiring firm. Our results indicate that firm credit risk however is positively correlated with investment risk. After controlling for specific deal- and firm characteristics, our findings suggest that managerial hubris decreases the level of credit risk and increases the level of investment risk in acquiring firms. Our results are consistent with the asymmetric information hypothesis that managers may exploit the volatility of their stock price to hide risk-increasing activities. We also observe that acquirers with high pre-deal credit risk undertake acquisitions that decrease credit risk and increase investment risk. We find no significant impact from neither method of payment nor valuation errors.
