本文主要研究兼收并购目标公司进行股权回购对于并购结果的影响。通过对美国1995年至2010年间媒体报道可能收到并购要约的公司样本进行分析，本文主要有以下发现：首先，股权回购能够降低目标公司实际收到并购要约的可能性；其次，对于市场传闻属实，的确收到要约的公司，股权回购能够降低公司被成功收购的概率。以上的发现与理论研究相符合，证明了股权回购能够有效的阻止目标公司被收购。进一步的，本文分析了该种防御性股票回购对于目标公司股东的影响。假设目标公司管理层进行回购的目的仅仅是为了自身利益而防止公司被收购，那么该举措将降低公司的价值以及股东的回报率。相反的，如果目标公司管理层进行回购的目的是防止公司价值被低估，并提高其在并购谈判中的议价能力，那么该举措将增加公司的价值以及股东的收益。通过对成功的并购案例进行实证分析，本文发现股票回购能够提高目标公司在并购整个过程中的收益。具体地，进行股权回购的目标公司相比收到现金的可能性增加，收到现金所占整个交易额的比例增加，并能获得更高的报酬率。另外，收购方的收益并不会随之增加，说明回购使得市场上调对于目标公司的估值，并且全部相应的收益都被目标公司得到。这从另一个方面说明目标公司的议价能力上升。 / This paper examines the effect of target share repurchase on outcomes of possible takeover attempts between 1995 and 2010. Consistent with deterrent effect hypothesis, I find that rumored targets are less likely to receive actual bids if they use share repurchase as a self-defense strategy. Moreover, for the subsample of rumored targets that receive bids afterwards, I find a significant negative relation between share repurchase and the likelihood of deal completion. Furthermore, I test the hypothesis that share repurchase is used by self-interested target managers for entrenchment purpose, and as a result the cost of signaling may lead to lower premiums for target shareholders. As an alternative hypothesis, share repurchase may increase bargaining power of target managers and result in better negotiated terms. Consistent with the enhanced bargaining power hypothesis, I find that target share repurchase is associated with higher probability of receiving cash as part of payment, with higher percentage of cash received, and with higher target takeover premiums. / Detailed summary in vernacular field only. / Xia, Yidan. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 29-30). / Abstracts also in Chinese. / Chapter I. --- Introduction --- p.1 / Chapter II. --- Data collection and summary statistics --- p.6 / Chapter A. --- Sample Construction --- p.6 / Chapter A.1. --- Rumor sample --- p.7 / Chapter A.2. --- Complete Sample --- p.8 / Chapter B. --- Sample Description --- p.9 / Chapter C. --- Variable Construction and Summary Statistics --- p.11 / Chapter C.1. --- Repurchase variables --- p.11 / Chapter C.2. --- Premiums --- p.12 / Chapter III. --- Empirical Results --- p.17 / Chapter A. --- Deterrent Effect --- p.18 / Chapter A.1. --- Probability of Receiving Actual Bid --- p.18 / Chapter A.2. --- Probability of Deal Completion for Firms Received Bid after Rumor --- p.19 / Chapter B. --- Bargaining Power --- p.20 / Chapter B.1. --- The Relation between Repurchase and Payment method --- p.20 / Chapter B.2. --- The Relation between Repurchase and Target Premiums --- p.22 / Chapter B.2. --- The Acquirer Returns --- p.24 / Chapter IV. --- Conclusions --- p.27 / Appendix --- p.28 / References --- p.29 / Tables --- p.31

Thesis (MBA)--Stellenbosch University, 2007. / ENGLISH ABSTRACT: Share repurchase activity (or buybacks), as a corporate finance decision-making tool, has increased steadily over the years, both in the USA and in other markets around the world. This research report investigates share repurchase (of ordinary shares) activity in South Africa between July 1999 (when buybacks were legalised) and December 2006. Consistent with empirical evidence elsewhere in the world, the results show that South African companies have increased their share repurchase activity in absolute terms (volume and value). Corporate South Africa is estimated to be sitting on a huge cash pile of approximately R600 billion (or 38% of GOP) - a significant prerequisite for share repurchases. In the absence of potential projects and acquisitions that meet the firms' weighted average cost of capital, it is reasonable to expect that the level and value of buyback activity will increase in the foreseeable future. / AFRIKAANSE OPSOMMING: Die aandeleterugkoop-bedrywigheid (of aandeleterugkope), as 'n korporatiewe finansiele besluitnemingshulpmiddel, het geleidelik toegeneem oor die jare, beide in die VSA en in ander markte wereldwyd. Hierdie navorsingsverslag ondersoek die aandeleterugkoop-bedrywigheid in Suid-Afrika tussen Julie 1999 (toe terugkope wetlig geword het) en Desember 2006. In Iyn met empiriese bewyse elders in die wereld, toon die resultate dal Suid-Afrikaanse maatskappye hul aandeelterugkoop-bedrywighede in absolute terme (volume en waarde) verhoog het. Oit word beraam dat korporatiewe Suid-Afrika 'n groat kontantreserwe van bykans R600 biljoen (of 38% BBP) het - 'n noemenswaardige voorvereiste vir aandeleterugkoop. In die afwesigheid van potensiele projekte en aankope wat die firmas se geweegde gemiddelde koste van kapitaal behaal, is dit aanvaarbaar om te verwag dat die vlak en waarde van terugkoopbedrywigheid in die afsienbare toekoms sal verhoog.

M.Comm. / The purpose of this dissertation is to determine the role and responsibility of the auditor in assessing the going concern status of South African companies implementing buybacks. The provisions of current legislation in this regard, including the Companies Act and the JSE Listing Requirements will be discussed and the question of whether the current status of the auditor's involvement in the buyback process is sufficient will be explored. Furthermore, since no specific requirement regarding the going concern assessment with regard to buybacks is placed on the auditor in terms of the Companies Act or the JSE Listing Requirements, the responsibility of the auditor with regard to the going concern concept within the scope of a normal statutory audit will be explored. A workable guideline will be developed to assist the auditor in assessing the impact of a buyback on the company's ability to continue as a going concern and consideration will be given to the process that the auditor should follow in reaching a conclusion on whether a buyback raises a material uncertainty surrounding the company's ability to continue as a going concern. However, before the issue of the auditor's responsibility with regard to the going concern concept in relation to share buybacks can be addressed, it is necessary to obtain an understanding of the legislation, financial, accounting and taxation implications of buybacks. These factors will be addressed in this study before the auditor's involvement in the buyback process is evaluated.

This study is an empirical investigation of the managements’ motivations behind corporate equity repurchases in the open market, via private repurchase, or through self tender offer. The hypotheses concerning motivations for stock repurchases investigated in this dissertation include (1) signalling undervaluation of stock prices; (2) free cash flows; and (3) increasing leverage. A series of statistical analysis and tests are conducted against the empirical implications concerning the three decision variables in a repurchase decision process: (1) whether to repurchase; (2) what method (self tender, open market, and private repurchase) to use; and (3) the size and the price of repurchase under each motivational hypothesis, using the sample of all repurchases announced from January, 1986 through April, 1989. The motivational proxies are (1) the percentage changes of the median (and mean) earnings forecasts in the first, second, third months after the announcement of a repurchase program from the month prior to the repurchase for signalling hypothesis; (2) Tobin’s Q, the ratio of a firm’s total market value to the market-value replacement costs of its assets, based on the Lindenburg-Ross Algorithm for the free cash flow hypothesis (another measure is also used in this dissertation, that is, the net cash flow after taxes and dividends relative to the market value of a firm’s common stock); arid (3) the market-value based debt-equity ratios for the increasing leverage hypothesis. The empirical portion of this study is composed of four sections: (1) a comparison study of subsamples of repurchases with their control samples of non-repurchasing firms constructed by the criteria of data availability in both the /B/E/S and the COMPUSTAT database, three-digit industry code, and the market value of common stocks; (2) a comparison study of the three repurchasing methods; (3) the determination of the terms of repurchases; and (4) the market reaction to the announcement of repurchase and its relationship with the motivational proxies. The major conclusions of this study are as follows: 1. The signalling hypothesis is supported for the sample of open market repurchases which occurred over the 1987 crash period (from October 19 to November 9, 1987). 2. The free cash flow hypothesis is supported for the sample of ordinary open market repurchases which occurred outside the 1987 crash period. 3. None of the three motivations investigated in this study is supported for the sample of private repurchases. 4. The results are not conclusive for the sample of self tender offers, though the signalling hypothesis and the free cash flow hypothesis are not rejected. / Ph. D.

Thesis (PhD)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Share repurchases were allowed in South Africa as from 1 July 1999. The concept of repurchasing shares is therefore relatively new in this country, compared to many other countries (e.g. the United States of America and the United Kingdom), where it is an established practice. Considerable research in the field already exists, providing empirical evidence on the extent of share repurchase activities and current theoretical thinking on the motivations for share repurchases and the determinants affecting the choice of payout methods. In South Africa there are indications, as this study demonstrates, that research on payout methods and payout reform has become a matter of urgency. Share repurchase activity by JSE-listed companies is not comprehensively recorded by South African financial data sources. Prior research on South African share repurchases is limited, mainly owing to the fact that a comprehensive share repurchase database is not available. This study sets out to document the extent of share repurchases by companies in selected JSE-listed sectors (for reporting periods including 1 July 1999 to the 2009 year-ends of the companies) and to test whether empirical evidence and current theoretical thinking also applied in South Africa. The results of these tests were used to develop a model to ascertain what the significant determinants were when a JSE-listed company had to decide between repurchasing shares and paying special dividends. This study found that the South African regulatory environment pertaining to share repurchases differed from the regulatory environments of other countries. The main differences related to the share repurchase announcement structure (namely the JSE Listings Requirements that open market share repurchases need to be announced via SENS only once a 3% limit has been reached) and that subsidiaries are allowed to repurchase shares in the holding company (and have a tax benefit when compared to share repurchases made by the holding company itself). These differences affected the results of this study. On compiling a database on share repurchases by companies in selected JSE-listed sectors, it was found that the share repurchase announcements (made via SENS) could not be used as the main source to compile comprehensive share repurchase data (mainly owing to the 3% rule on open market share repurchases). Annual report disclosures were therefore scrutinised to obtain share repurchase data for this study. These disclosures were found to be applied inconsistently by companies (mainly because subsidiaries were allowed to repurchase shares in the holding company; International Financial Reporting Standards and the JSE Listings Requirements did not adequately cater for the differing South African regulatory environment in their disclosure stipulations; and compliance to the disclosure requirements were not adequately monitored). Consequently, an extensive process of verification was applied in order to compile a comprehensive and reliable share repurchase database for this study. When testing whether empirical evidence and current theoretical thinking on share repurchases also applied in South Africa, it was found that the unique South African regulatory environment led to certain aspects of the South African share repurchase experience not mirroring the global precedent. The main differences between the South African and global share repurchase evidence which emerged from the present study are that the open market share repurchase type is not the outright favoured repurchase type (as is the case globally); that subsidiaries repurchasing shares in the holding company are the favoured South African share repurchasing entity (as opposed to subsidiaries not being allowed to repurchase shares in most other countries); and that share repurchases announced via SENS do not represent comprehensive share repurchase data (as opposed to global security exchanges requiring share repurchase announcements on a regular and accurate actual-time basis). When testing the current theoretical thinking on the information-signalling motivation for share repurchases, it was found that the motivation for South African open market and pro rata share repurchases mirrored the current theoretical thinking. Open market share repurchases were found to be motivated by the information-signalling hypothesis, while the short-term abnormal returns of pro rata offers were offset by the negative abnormal returns over the long term. A share repurchase type unique to the South African share repurchase environment (namely the repurchase of treasury shares by the holding company) was found not to be motivated by the information-signalling hypothesis. This study also found that companies repurchasing shares were generally classified as value companies (which tend to be undervalued) prior to the repurchase transaction which mirrored the current theoretical thinking. In developing a model of choice to determine what the main determinants were when a company had to decide between open market share repurchases and special dividends, this study found that some of the South African determinants mirrored the current theoretical thinking, but also identified determinants which were not identified as significant determinants in global research. This study found that ownership structure, size of the distribution and level of company undervaluation were the significant factors which affected a company’s choice of payout method. It was found that smaller companies, with fewer shareholders and more public investors favoured open market share repurchases over special dividends. Open market share repurchases were found to be selected for smaller distributions when compared to special dividends. Companies paying special dividends were found to exhibit lower degrees of undervaluation when compared to companies which repurchased shares in the open market. This study found that share repurchases became a popular means of distributing excess cash as from 2005. A total amount of about R384 billion was spent on share repurchases during the reporting periods including 1 July 1999 to the 2009 year-ends of the companies included in the population of this study. Share repurchases did not exceed dividend payments over the target period and represented about 36 per cent of total payouts. In 2009, the final year of the study, share repurchases represented about 44 per cent of total payouts. The results of this study showed that investors would benefit over the long term when investing in companies which repurchased shares in the open market. It was also found that there were certain characteristics which were evident in companies when choosing open market share repurchases rather than special dividend payments. This study concluded that the South African regulatory environment possesses many characteristics of a developing economy’s financial systems. Suggestions are given on how to improve and better align the South African repurchasing environment to those of developed economies.

Thesis (MBA)--University of Stellenbosch, 2011. / In the absence of clear accounting guidelines, the closing number of shares reported in the company annual report is not always equivalent to the closing balance of the group shares. The closing balance of the number of shares of 111 companies listed on the Johannesburg Stock Exchange, for the period 2000 to 2009, was analysed and compared to an electronic database, managed and maintained by the Graduate School of Business of the University of Stellenbosch, on which a reconciliation of the closing number of group shares was recorded for the companies selected. In addition, the effect of the incorrect number of shares reported in the annual report was compared to the net asset value and/or tangible net asset value ratio, to the extent that the information was available. For the purposes of this empirical study, the mining, most of the financials, development capital and alternative exchange sectors were excluded.
