A Study of Wealth Effects of Takeover Announcements in India on Target Company Shareholders

Abstract

The business strategy of inorganic growth is carried out by companies by resorting to actions which prominently include mergers, takeovers, and strategic alliances. There is a rapid growth of both mergers and takeovers in India subsequent to the economic liberalization. The companies consider takeover activity as the quickest means of corporate growth to enhance their size and face the domestic and global competition.In spite of several decades of vast research, researchers have not come to the final conclusion on the wealth effect of announcements of takeovers on the shareholders of participating companies. While some studies justify takeover as a socially productive activity which creates value for the shareholders, others provide contrary evidences to show that they destroy value for the shareholders. In India, only some studies have analysed the impact of M&A announcements on the stock return performance of companies involved and there is lack of evidences on wealth effects on shareholders. Therefore, this paper assesses the impact of takeover announcement on the stock price performance of target companies by taking a sample of 227 companies which received takeover bids during 1998–2007. The stock price reaction is examined for a period of 61 days surrounding the bid announcement day employing standard market model. BSE- 200 index is used as a proxy for the market. The regression co-efficient and the constant terms are estimated over a period of 250 days (-280 to -31) and the statistical significance of the results of the study is determined by non-standardized and standardized abnormal return methods. Both raw returns and log returns are examined.Results of the study show that target company shareholders experience substantial and statistically significant cumulative average abnormal returns (CAARs) of 27-37 percent — 37 percent when raw returns are employed and 27 percent when log returns are employed. The conclusions remain unchanged irrespective of the testing procedure used (i.e., non-standardized or standardized abnormal returns method) and even for several shorter event window periods within a broader event window of 61 days. The results for target companies are consistent with the evidence of extant research that major benefits from M&As accrue to target company shareholders. The practical implication of the study is that there is a large and significantly positive wealth effect on the target company shareholders in response to the announcement of takeovers. Takeovers offer an opportunity to shareholders of target companies and general investors to make profits both in the period before and after the announcement of the takeover bid.
