This paper attempts to examine the impact of merger on the stock returns and economic value added (EVA) of acquiring firms to know if the mergers are successful corporate restructuring strategies for the firms.

In total, 108 Indian firms are studied using paired sample t-test and Wilcoxon signed rank test for comparing the EVA of acquiring firms in short, medium and long term after merger. The effect of merger announcements on stock returns is analyzed by way of event study. An event window of −20 to +20 is taken and an estimation window of 256 (-276 -20) days is used in the study.

The authors find that mergers lead to significant improvement in the EVA of acquiring firms. However, the increase in financial performance and EVA is witnessed only in long term. The authors did not find any significant impact of merger announcement on the stock returns of acquiring firms.

The study is a first of study's kind, which evaluates both short-term (using event study methodology) and long-term (using EVA) impact of value addition to an acquirer after Merger & Acquisition (M&A). The study contributes to existing literature on the signaling theory of announcement of M&As and synergy gain theory of completed M&As by providing evidence from the context of an emerging market like India.

This study examines whether mutual funds buy or sell the stock of merger targets advised by their investment bank affiliates in advance of merger announcements and withdrawals. Existing literature finds mixed evidence on whether financial conglomerates act on conflicts of interest across divisions.

Affiliations between investment banks and mutual funds are identified, and the incidence and characteristics of mergers where funds trade the stock of targets advised by affiliates are examined.

Mutual funds buy or increase holdings of merger targets advised by their investment bank affiliate in advance of merger announcements, capturing highly positive abnormal returns. Mergers with this pre-announcement trading by affiliates are more likely to be completed successfully. Furthermore, mutual funds are more likely to liquidate holdings of a target in advance of a merger withdrawal if the fund is affiliated with the target's investment bank advisor, thus avoiding negative abnormal returns surrounding merger withdrawals. Results are robust after controlling for potential sample selection bias.

These findings contribute to the literature on affiliations between investment banking and mutual fund management, M&A outcomes, and to the discussion of potential conflicts of interest within banks. Also, this study is the first to examine trading activities by mutual funds affiliated with merger investment bank advisors during value-sensitive periods beyond the pre-announcement phase, such as the time period leading up to merger withdrawals.

The paper investigates the market performance of strategic acquisitions for growth in the fifth and sixth merger waves and outlines the major determinants that affect the performance of acquiring companies in these most complex and most challenging corporate transactions.

To perform the quantitative analysis a unique data sample was built out of acquisitions performed in the 5th and 6th merger waves with an only single purpose – strategic growth. Their performance was first analyzed using the method of market-based event study. In addition, the impact of several non-accounting determinants identified through a thorough literature review was tested using univariate/multivariate regression analysis.

The new findings of the study state that strategic acquisitions for growth created more value for acquiring companies if they were completed internationally and involved an acquisition of a middle-sized company. Moreover, the acquisition of targets in the less related industries (2-SIC) led to stronger performance of acquirers, especially in the international settings.

The study suggests additional directions for future research. The future analysis can investigate the post-merger acquisition performance of strategic acquirers and can focus on additional financial (accounting) determinants in the evaluation of performance. This perspective can not only address the limitations imposed by the assumption of efficient capital markets but also provide additional insights.

The results of current study have important implications for executives performing M&A for growth. They show that the market reaction to M&A announcement can be at least partially anticipated and help managers to plan their strategic moves based on a defined set of variables.

The study contributes to the sustainable, value-creating growth dynamics and encourages Executives to “lead for value.”

(1) In contrast to the existing studies that do not differentiate between the transaction rationale in their analysis, this paper focuses explicitly only on those acquisitions that have strategic growth as their primary objective and responses therefore, to the problem stated by Halpern (1983). This approach helps to mitigate the distortion of results and make a reliable assessment of the strategic move. (2) The results of quantitative analysis also outline that acquisition of mid-sized targets and larger degree of diversification (2-SIC, international focus) code were associated with higher value creation.

本文旨在研究於第五和第六波的併購浪潮中為增長而作出的策略性收購的市場表現;本文亦概述在這些極其複雜的和極具挑戰性的公司交易中影響作收購公司的表現的主要因素.

為了能進行定量分析,研究人員收集在第五及第六波的併購浪潮中以策略性增長為唯一目的的收購個案、建立一個獨特的數據樣本。研究人員首先以基於市場的事件研究法分析那些進行了收購的公司的表現,並以單變量/多變項迴歸分析法去試驗那幾個透過深入的文獻研究而找到的非會計的決定因素的影響.

研究得出的新發現是、如果以增長為目的的策略性收購是於國際間完成及涉及收購中型公司的話,則這收購行動會給進行收購的公司帶來更多價值。而且、如果收購目標的產業與作收購公司的不太相關的話 (2-標準產業分類),收購行動會為進行收購的公司帶來更強的表現、特別是在國際環境下進行這收購行動.

(1) 有別於現時其它於其分析中不區分交易理由的研究，本文明確地表示只集中探討那些以帶來策略性增長為主要目標的收購；因此、本研究對 (哈爾彭，1983年)(Halpern, 1983) 陳述的問題作出了回應。本研究的理念有助於減輕我們對收購結果的曲解，從而讓我們對策略性行動能作出可靠的評估. (2) 定量分析的結果、亦概述了以中型公司為目標的收購及更大程度的多樣化 (2－標準產業分類、以國際為焦點) 代碼與創造更大價值是有關聯的。

本研究的結果對學術界及管理人員均具吸引力，亦為策略規劃提供一個額外的工具.

本研究可帶來可持續的及可創造價值的增長動力，又可鼓勵行政主管採用以價值為本的領導方針.

The purpose of this paper is to examine the impact of regulatory changes by the US Securities and Exchange Commission in 2000 on private information leakage prior to merger announcements.

Using a sample of 5,045 merger announcements between 1990 and 2008, the authors examine differences in information leakage between the pre- and post-regulation period merger announcements for acquirers using regression analysis.

The results suggest that regulatory changes have been effective in preventing private information leakage in merger announcements for large- and medium-sized firms, for high-tech firms, and for stock deals. The authors find that abnormal trading volume due to differences in information quality is reduced post-regulation for stock deals, high-tech firms, large- and medium-sized bidders, indicating less leakage of information after the new regulations. The authors find higher announcement returns post-regulation for the entire sample and for all subsamples except stock deals, small firms, and public targets. Higher announcement returns indicate that merger announcements are a greater surprise to the market due to a reduction in leaked private information after the regulatory changes.

The results have implications on future rule changes, on refinements of insider trading rules, regulation fair disclosure, and regulation M-A. The authors leave for future research why certain types of firms or deals are not impacted by regulatory changes.

Examine the effect of changes in information environment on merger announcements for acquirers because the impact likely has greater significance on acquirers than that on targets. Past studies have examined only targets.

The purpose of this paper is to investigate the wealth implications of bank mergers and acquisitions (M&As) in the unique Greek setting given the triple crisis phenomenon – banking, sovereign debt and economic crises – that prevailed after the global financial crisis.

The study examines bank M&As and bank transactions over the period from 1997 to 2018, as well as government-assisted M&As during the crisis. The wealth effects of bank M&As are assessed using both univariate and multivariate frameworks.

Findings show a neutral crisis effect on the valuation of M&As upon their announcement. However, the authors provide conclusive evidence that M&A completions are value-destroying events for acquiring banks during the crisis, far worse than in the pre-crisis period. Greek banks also fail to create value from government-assisted mergers. The results suggest that the financial stability and the prevention of further deepening of the Greek crisis with possible contagion effects were achieved at the expense of shareholders and taxpayers.

To the authors’ knowledge, this is the first study that examines the impact of the Greek triple crisis on the wealth effects of bank M&As and bank transactions. Also, the study provides first evidence with regard to the economic impact of government-assisted M&As in the European context.

The purpose of this chapter is to reflect the impact of mergers and acquisitions processes on performance of Islamic banking industry in the United Kingdom through studying within.

The present research uses explanatory approach in order to examine the research problems, methodology used in the research is quantitative methods through calculating the long-term share prices performance of the UK Islamic banks’ sample. First, the researchers use the control Islamic bank in the event-time approach. The researchers calculate annual abnormal returns using the buy-and-hold abnormal return (BHAR) method over a period of five years, counting from the quarter of a year when the transaction is said to be effective.

The research findings found that there are significant differences in the Islamic mergers and acquisitions post-long-run performance of the UK Islamic banks to the control the crises that face the United Kingdom from 2007 to 2010. However, the acquiring Islamic bank in high-tech industries had a negative effect on their long-term performance.

The present research has been applied for the Islamic banking industry in the United Kingdom after the Western Europe industry from 2007 to 2010.

The main implementations of the present research is valuing UK banks carried out the Islamic mergers and acquisitions of a broad range of management disciplines encompassing the financial, strategic, behavioral, operational, and cross-cultural aspects of this challenging and high-risk activity.

The Islamic mergers and acquisitions have placed a significant amount of value added on the motivation of large banks for engaging in banking mergers and acquisitions’ transactions.

The purpose of this paper is to examine the relationship between price movements of target firms’ stocks and behaviors of local individual, local institutional and foreign investors in trading target firms’ stocks around mergers and acquisitions announcements in Korea.

This study uses event study methodology and cross-sectional regressions for abnormal returns.

Results reveal that the average abnormal return becomes significantly positive three days prior to the announcement date and becomes insignificant after the announcement date. Results also show that local individual investors tend to sell more intensely prior to announcements for target firms with larger wealth effects. In contrast, foreign investors tend to buy target stocks with larger wealth effects more intensely prior to the announcement date, and then they sell them more intensely in the post-announcement period.

This paper provides evidence that foreign investors are able to identify target stocks with large wealth effects prior to the announcement date and they realize short-term profits by selling them following the announcement.

This paper aims to examine whether an exogenous shock to the supply of financial capital mitigates agency conflicts between managers and shareholders and incentivizes managers to channel available financial resources into value-increasing acquisitions.

The authors use a difference-in-differences approach to mitigate endogeneity concerns. To address the concern that substantial differences between the treatment and control groups may violate the parallel-trend assumption of the D-in-D approach, the authors use a propensity score-matching procedure and construct a matched sample for their empirical analysis.

The authors find that below-investment-grade firms are significantly less likely to make acquisitions relative to unrated firms following the collapse of the junk bond market in 1989. Conditional on initiating a successful acquisition, below-investment-grade acquirers are less likely to acquire diversifying targets and public targets, but more likely to acquire subsidiary targets. In addition, below-investment-grade acquirers experience higher post-merger operating and stock performance for acquisitions initiated in the post-shock period.

The authors demonstrate that capital shocks negatively impact managers’ propensity to make acquisitions, which are considered a well-established outlet for agency conflicts between managers and shareholders. In addition, managers who are subject to capital shocks tend to manage available financial resources more efficiently and make better acquisition decisions that lead to greater value creation.

Acquisitions are complex and ambiguous events fraught with information asymmetries emphasizing market failure before an acquisition or organizational failure during integration. While often treated in isolation, market and organization failure are intertwined in acquisitions as integration planning starts before a deal is closed. Effective integration begins with a deep understanding of the target to be able to share assets and knowledge. However, acquiring firms currently have limited solutions to address information asymmetries. Most remedies primarily aim at market failure using due diligence and external advisors, leaving information asymmetry due to organizational failure primarily unattended. The authors develop a typology that leverages informal and formal social ties to address information asymmetries across the acquisition process that jointly considers market and organizational failure. The typology of this study combines existing research to develop how social ties with stakeholders influence acquisitions and can increase their success.

This paper aims to address the question of whether acquiring firm directors trading, prior to a merger or acquisition (M&A) announcement, predicts the share market reaction on M&A announcement.

Event studies and cross-section regression were used in this analysis.

This paper finds that acquiring firms with no director trading and firms with net director purchases in the 12 months prior to the M&A announcement earn positive abnormal returns. It is also found that share market reaction to M&A announcements is considerably larger for acquiring firms whose directors do not trade relative to those companies with directors who do trade over the prior 12 months. This director non-trading result is further born out in regression analysis.

The absence of pre-M&A announcement director trading could reflect lower agency costs for the acquiring firm and this might explain to stronger announcement day effect for this group of firms.

The fact that directors choose not to trade in their shares prior to a M&A transaction appears to be viewed as good news by the market.

Director trading is value relevant for the acquiring firm and so it is critical that director trading is transparent.

To the best of the authors' knowledge, this question has not been addressed in the literature before, particularly the finding for firms with no director trading in the period prior to the M&A announcement.
