In the current challenging business environment, acquisitions face a higher degree of risk profiles, especially cross-border acquisitions in the emerging markets. Conducting a thorough due diligence investigation in the context of an acquisition is more important now than ever. In a broad analysis, this paper researches the key risk factors in the acquisition process and their assessment within a due diligence audit in the acquisition phase. The task of this paper is to match the academic and practical view in order to give a more complete understanding of risk factors to be covered in due diligence audit. The starting point is the research of academic findings which basically concentrate on common approaches considering financial, legal, commercial, and some other issues in domestic acquisitions and in developed countries. In contrast, this paper considers risk factors in cross-border and emerging markets transactions. In addition, a number of business consultants publish studies based on surveys on this topic which reflect typical risk factors based on experience of their customers being involved in cross-border acquisitions. Their risk assessment consists of specific regulatory, political, and other factors, which may lead to commercial and reputational impediments in cross-border acquisitions. The outcome of the comparison is a comprehended list of evaluated risk factors, whereby the academic findings are complemented and supported by the practical experience in the business consultant's studies. Moreover, the practical approach points to the fact that due diligence scope needs to be suited to the dynamics of the markets. The comparison and the comprehended list of evaluated risk factors call for a more integrated system of due diligence and show herein the research deficit. Hence, the novelty is the compendium of evaluated risk factors which should be assessed in the pre-acquisition phase. The originality of the paper is given by a unique analysis of academic work about acquisition due diligence literature and consultant studies from anonymized practical experience based on insider information.展开更多

Different types of mergers occur under different situations. Mergers between companies which have same products or services called horizontal mergers; mergers between companies which have buyer-seller relationship called vertical mergers; and companies which have different business fields always use conglomerate mergers. The main motive of companies or firms choosing merger or acquisition is synergy.展开更多

Using 125valid collected questionnaires, multiple linear regression analysis and hierarchical regression analysis showed that five out of the ten factors had a positive effect on knowledge transfer effect. The ranking of factor importance, from high to low, was knowledge explicitness, relationship quality, learning intent, advanced transfer activities, and learning capability, which is fairly consistent with positive factors observed in other interorganizational knowledge transfer researches. Our results also showed that one of the control variables(size of acquired firm) had neither a direct or indirect effect on knowledge transfer in M&A. Additionally, our research found that knowledge distance and degree of M&A integration had a positive influence on knowledge transfer effect at the early stage after M&A, but had a negative influence at the late stage. Based on this research, several suggestions for knowledge transfer in M&A are proposed.展开更多

Enterprises go through the process of Mergers and Acquisitions (M&A) with the goal of improving performance, increasing efficiency and obtaining business synergy. Prior literature suggests that synergies could arise due to taxes, market power or efficiency improvements. This study evaluates the efficiency of M&A in Brazil among publicly-traded companies. We used models with multiple objectives from Goal Programming and Data Envelopment Analysis (GPDEA), employing accounting indicators as input and output variables, and thus evaluated the emergence of synergy gains. These models allow us to analyze and classify the M&A according to the efficiency obtained in such processes. Some of the M&A cases analyzed were mistakenly considered efficient when used traditional models. And, as expected, the GPDEA was proved to be superior to classical models;however it was noticed that few of the cases investigated were proved to be effective. We presented a new application for multi-objective approach that can be used to assess mergers and acquisitions. The dualapplication of GPDEA provided a greater understanding of efficiency generation in synergy creation by means of M&A.展开更多

Meanwhile, the trade policy of the host government is taken into account. It is concluded that the more open the economy and the more intense the competition, the less profitable the integration; the most important determinant to the changes of the domestic social welfare is the industry strength of the host country. The host authority can enhance the domestic social welfare in two ways: to adjust the trade policy and to only approve the socially desirable cross-border mergers and acquisitions.展开更多

If the capital market is competitive, the investors cannot expect superior gains from their investment strategies with respect to the risk profile. Event studies are an approach to verify the impact of the information on the stock prices. In an efficient market, stock prices should fully, promptly, and quickly capture all the information. Instead, the market shows phenomena of an under-reaction and over-reaction for both the short and the long run. The mergers and acquisitions (M&As) are examples of anomalies. Often, the bidder companies record the negative abnormal returns for both the short and the long run. In contrast to the efficient market theory, the empirical evidence shows that this phenomenon is widespread in all (or most of) the countries of the world. This work examines the long-run performance in M&As. For this purpose, 40 bidders were observed in Italy during the period of 1994-2008 among listed companies. The buy and hold abnormal returns (BHARs) methodology was used, with which it was possible to observe the returns for three years following the deal.展开更多

In the upcoming 10 years, fundamental changes will be made with the economic growth in China. Against this background, China' s steel industry will shift from a rapid development to a slow but sound development. In order to fulfill the second leap of China's steel industry, based on its current developing status and characteristics, and from the perspective of both national and corporate development, mergers and acquisition are both effective ways to raise the quality of the existing stock of asset in the steel industry, while technological innovation is the solid foundation for its second leap.展开更多

Two 100?MHz ADC modules worked parallelly and every ADC plays out data in ping pang fashion. The design improved the system conversion rata to 200?MHz and reduced the speed of data transporting and storing to 50?MHz. The high speed HDPLD and ECL logic parts were used to control system timing and the memory address. The multi layer print board and the shield were used to decrease interference produced by the high speed circuit. The system timing was designed carefully. The interleaving/multiplexing technique could improve the system conversion rata greatly while reducing the speed of external digital interfaces greatly. The design resolved the difficulties in high speed system effectively. The experiment proved the data acquisition system is stable and accurate.展开更多

This research seeks to assess the impact of Chinese acquisitions and their implications for the "Made in Italy" luxury sector and its firms. This paper presents a cross-case analysis of two Chinese acquisitions in order to provide some in-depth insights into the influences and the motives driving Chinese firms to invest in the luxury Made in Italy sector, the patterns and modes of the Chinese acquisitions as well as the competitive strategies and the distinctive challenges that both investors and acquired firms have to face. From the findings, it emerges that both the investor and the acquired firm need to overcome several key challenges to be mutual benefits from the acquisition.展开更多

Better legal protection and stronger social norms improve minority shareholders' protection from expropriation. They consequently reduce the private benefits of controlling shareholders (La Porta, 1999). This study aims to investigate tunneling in the context merger and acquisition (M&A) and to examine whether tunneling occurs only in emerging markets with poor law enforcement or whether it also occurs in developed countries. This study documents that managers are more likely to overpay target in merger and acquisition with high overlapped owner which have stakes in bidder and target firm. That overpayment, a transfer of wealth from owners of bidder's firm to overlapping owners, is a type of tunneling. This study concludes that tunneling occurs in nations not only with low investor protection, but also with high investor protection.展开更多
