Mergers and acquisitions (M&A) can be either “hostile” or “friendly” in nature. This study looks at the corresponding long-term investment performance of “hostile” and “friendly” takeovers within the mining sector, pre and post the takeover of targets, with the aim to investigate whether there are statistically significant differences about which the investor community should be aware.36 months of monthly share price performance, pre and post first formal merger/takeover announcement date, are studied, for each acquirer is compared with the bourse mining index to calculate the percentage time the acquirer outperforms the market (mining index). Research of the major mining stock exchanges of the world – New York, Toronto, Australia, London and Johannesburg – reveals that the investment performances of “hostile” acquiring mining companies, pre first formal announcement date, are statistically significantly greater than post first formal announcement date. No statistically significant difference was found pre and post first announcement date for “friendly” acquiring mining companies. Although clear differences in post first formal announcement date investment performance are noted between “hostile” acquirers and “friendly” acquirers, there is no statistically significant difference between the investment performances of “friendly” versus “hostile” acquirers. / Dissertation (MBA)--University of Pretoria, 2006. / Gordon Institute of Business Science (GIBS) / unrestricted

Star cluster formation involves the conversion of molecular gas into stars inside giant molecular clouds (GMCs). Such a process involves many dynamical evolution mechanisms, including mergers between smaller star clusters (subclusters) on which we focus in this thesis. We take results of simulations performed by Howard et al. 2018 (H18) which found that young massive cluster (YMC) formation is heavily dependant on the process of subcluster mergers, and we simulate said mergers at higher resolution. Subclusters inside such GMC simulations are modelled using the sink particle prescription which does not resolve individual star particles or gas parcels inside the subcluster they represent. We employ a more controlled method in simulating subcluster mergers to better understand the response of the stellar and gas components of a subcluster from the merger process. To do this, we take the parameters of the sink particles created in H18 and set up spheres of stars and gas. We use the AMUSE framework to couple the N-body evolution of the stars to the smoothed particle hydrodynamics (SPH) evolution of the gas such that both components of a given cluster can realistically react to each other. We model 15 of these mergers and find that once the velocity at which the two clusters collide (collisional velocity) exceeds $\approx 10$kms$^{-1}$, the resultant cluster is not monolithic (i.e. it still contains two separate stellar components) while all other simulations merge into one monolithic stellar and gas component cluster. We also find that, regardless of the collisional velocity of masses of the component clusters, all resultant clusters lose a fraction of their stellar and gas mass. This fraction is directly proportional to the collisional velocity and is a discrepancy between the sink particle prescription (where all mass is contained inside a constant sink particle accretion radius) and real cluster mergers. A further discrepancy we find is that all simulations result in a cluster whose outermost regions are expanding and that the rate of this expansion is somewhat proportional to the collisional velocity of the merger. These results point to the inaccuracy of the sink particle prescription and allow us to develop tools to improve on it in future simulations. Next, we fit commonly used analytical density profiles to both the stellar and gas component of our resultant clusters and find that, while they do not provide particularly excellent fits, they provide constraints on what is an acceptable fit. Lastly, we analyze the amount by which gas with potentially star forming densities increase due to the merger and we find that all mergers increase their star forming gas mass fraction by roughly 50 per cent implying that mergers may be an effective tool for triggering star formation. / Thesis / Master of Science (MSc)

Using a sample of 45,283 firm year observations between 1993–2012, I examine the influence of different types of diversification and M&A accounting on firm value. I find that there are different explanations for earlier variations among documented discounts. I find different value effects for geographical and industrial diversification. These effects vary over time, with decreasing discounts for geographical diversification. Furthermore, I find different value effects of M&A accounting between industries. Controlling for firm fixed effects leads to insignificant results for most regressions, which indicates that underlying firm characteristics play an important role in the determination of the discount. Together, these findings explain earlier documented differences in the literature on the diversification discount.

The number of domestic and cross border bank mergers and acquisitions (M&A) has increased over the last decade with a resultant impact on the bank dividend. This study examines the effect of M&A on the dividend policy by comparing the abnormal returns, profitability and dividend policy of the domestic and cross border bank acquirers. The study focused on EU mega-bank mergers and acquisitions within 1997-2007 involving only commercial-to-commercial banks. The sample consists of a total of 62 mega-M&A with a minimum deal value of €500 million. Three hypotheses were formulated specifically to test: (i) the wealth effect and geographical diversification of the M&A between domestic and cross border acquirers; (ii) the effect on in the financial performance of both acquirers and (iii) the M&A impact on dividend policy on banks after bank M&A. Two strands of the literature were reviewed focusing on M&A and dividend policy. The event study methodology was used to calculate the abnormal returns of both the domestic and cross border acquirers which were standardised. A long window of 61 days was applied to capture a satisfactory length of pre and post merger events that could capture the behaviour of the abnormal returns and consequent effect on dividend policy. The hierarchical regression model was used to estimate the impact of the variables on the profitability and dividend policy of the acquirer banks. In comparison with the domestic acquirers, the cross border abnormal returns showed a trend of significant negative results following the M&A announcement. The domestic acquirers showed no significance but, on average have higher cumulative total standardised abnormal returns (CTSAR) than the cross border acquired banks. The result of the financial performance showed that CTSAR of the cross border acquirers is significantly affected by the profitability of the banks but insignificant with domestic acquirers. However, the cost-to –income ratio (CIR) significantly affects the performance of both bank acquirers. CIR and RISK (measured by the ratio of the loan provision to net interest revenue of the banks) highly correlated with profitability of both the domestic and cross border acquirers. The management of costs and loans risks were found to be significant variables in the achievement of profitability among domestic acquirers. The dividend policy hypothesis result indicated that CTSAR has a weak correlation and insignificant effect on the dividend policy variables. Infact, the Causality test result confirmed that the CTSAR does not Granger cause dividend policy. However, the study provides strong support to previous studies that beta, liquidity, taxes, and the finance structure of the acquirers are significant variables in the formulation of the dividend policy of the merged banks. The beta, which a proxy for risk, is the most significant factor affecting the dividend policy of the merged banks.

Around eighty percent of cross-border mergers do not succeed. Despite a substantial body of literature offering guidance on how to make them work, success remains elusive. Regardless of strategic direction, involving macro-level planning, restructuring of positions and improved remuneration, repeated failure indicates there is clearly a gap in our understanding. It is proposed that mergers and acquisitions (M&A) constitute a threat to social identity by disrupting longstanding patterns of relating between people. This is experienced as emotional anxiety, which is personally felt and collectively shared. In response, social defences are invoked that alleviate this distress but simultaneously inhibit the processes of recognition and conflict necessary to effect identity transformation. New relationships and connections do not therefore form and, consequently, new identity does not emerge. Hence, M&A fail. Attending to complex responsive processes of relating, particularly pertaining to the preservation and transformation of identity is crucial to the successful outcome of any M&A project. Using reflexive narrative, I have shown how anxiety and protective processes arise and offer insight into executive interventions that may be helpful. This research offers a new approach and an advance in our understanding of the social processes at work during M&A.

In the first chapter of this dissertation, I hypothesize that several non-tax-driven benefits of debt induce REITs managers to issue debt despite no apparent tax-driven benefit. Several methodologies and tests applied in capital structure literature are introduced to the literature of REITs capital structure. First, I investigate how the market prices leverage in absence of tax-deductibility benefit. Then, I diagnose the relative importance of several non-tax-driven benefits of leverage in deriving the capital structure decisions of REITs. Third, I conduct a thought investment experiment with debt-restricted vs. non-restricted REITs portfolios. I find weak evidence that leverage, by itself, creates value. Nevertheless, I find strong evidence that during financial crisis debt-restricted REITs perform better than non-restricted ones. Also I find evidence that lends support to the pecking order story of leverage. I conclude that REITs managers issue debt mainly to avoid issuing equity and to maximize wealth of existing shareholders. The second chapter addresses corporate diversification discount. I present and test a hypothesis that diversifiers exchange immediate diversification discount with future value gain attributed to unanticipated financial and strategic advantages of diversification. Two implications of this hypothesis are tested in this dissertation. First, the initial diversification discount found in static methodologies should be attenuated in a dynamic analysis. Second, diversifier's value evolution patterns are driven by the materialization of certain financial and strategic efficiencies. The overall results indicate that there is value recovery over time. Diversifiers' performance and value evolution is dynamically linked to synchronous improvements in market power, internal capital market activities, and cost efficiencies. Further, consistent with current evidence in diversification literature, related diversifiers outperform unrelated diversifiers. Moreover, related diversifiers witness faster value recovery relative to unrelated diversifiers.

The effectiveness of traditional due diligence practices and whether they contribute to Merger and Acquisition (M&A) success or failure is an ongoing debate in finance research. This research report contributes to the debate by examining the effectiveness of traditional due diligence using a qualitative research approach. A dataset of traditional due diligence practices was compiled from the literature, which formed the basis for an interview which was conducted with corporate finance practices. The findings indicate that the traditional due diligence process is considered to be an evolving process, where due diligence practices of the last decade are considered to be significantly different from the due diligence required in acquisitions today. Due diligence is also considered to be indispensable, and its scope and importance underestimated. Furthermore, any perceived deficiency in a due diligence is not necessarily in concept, but rather in execution, with excessive focus on the accounting and legal aspects of a M&A, while neglecting the macro-environment, marketing, production, management and information systems. It is also concluded that most stakeholders have understood that failure to carry out proper due diligence could be financially damaging to the parties transacting. In an attempt to determine what due diligence means for the current as well as the future, this study uncovers a critical trend in the forms and manner of flawed due diligence practices and paves the way to a more strategic due diligence, which are useful for practitioners in the present and in the future for M&A success.

Thesis advisor: Peter N. Ireland / This dissertation consists of two chapters. The first chapter: Does going to prison increase the chance that one eventually applies for U.S. disability insurance (DI)? Since the 1980's, there have been substantial increases in both the number of people who have been incarcerated and the number of people applying for DI. Both increases have caused higher costs to taxpayers. While several studies have explored the causes of the increased DI applications and several others have looked at the labor outcomes of ex-inmates, no study has yet asked whether prison itself has any effect on the DI application process. Prison, with its harsh conditions, could cause physical and mental disabilities that increase the chance of a DI application. Properly measuring this, however, requires considering any endogeneity that predisposes ex-inmates to a DI application prior to incarceration. To do this, I use the instruments of states' minimum wages and legal high school drop-out ages to explore the effect of increasing incarceration numbers on state-level DI applications. I find that prison does have a significant effect on DI applications; a 1.0% increase in incarceration causes approximately a 0.5% increase in DI applications six years after the initial increase in incarceration numbers. I find that prison's effect is especially strong for a means-tested group who also concurrently applies to Supplemental Security Income (SSI); here a 1.0% increase in prison leads to a 0.9% increase in people who apply for both DI and SSI after a six year lag. This suggests lower income groups are more sensitive to incarceration. Also, the cost of imprisonment should take into account the cost of subsequent DI applications and awards. The second chapter: This paper assesses the specific case of when a monopolist manufacturer producing two types of goods is allowed to bundle the goods when selling to retailers who are allowed to re-sell the goods individually, have territorial market power and have heterogeneity in the resale demand functions. While the literature covers bundling in a variety of forms, no paper has considered the effect that the presence of multiple retailers may have on an upstream manufacturer who bundles and how benefits to bundling may accrue to consumers, retailers, and manufacturer in the presence of retailer heterogeneity. It is shown that under plausible circumstances, the ability of a retailer to retain profit in the face of bundling may prevent consumers in other markets from realizing greater welfare-enhancing effects although bundling in these cases at least weakly improves consumer welfare and never diminishes it. It is also shown by example, that in the case of three retailers, some retailers may actually profit more when the upstream manufacturer bundles while other retailers may profit less. This suggests that in certain cases some retailers may even favor upstream bundling as their interests align with that of the manufacturer. / Thesis (PhD) — Boston College, 2015. / Submitted to: Boston College.
