Abstract

In this age of cut – throat competition, every company wants to grow and be ahead of its competitors. There are two ways to achieve growth- first the Greenfield expansions resulting in Organic growth in one’s own unit, and second the Brownfield expansions or M&As resulting in Inorganic growth. In a hurry to expand and beat the competitors profitably, the companies are restructuring themselves through M&As.

Mergers and Acquisitions (M&As) are the inorganic growth strategies which have become important in today’s corporate world due to increase in competition and complexity. The companies are expected to perform post M&A so that they create wealth for the shareholders. This paper is an attempt to review the major studies undertaken in the field of mergers and acquisitions across the globe. Various researchers have studied different aspects of M&As- ranging from the domestic and cross- border M&As, their causes, trends etc. to the impact of Mergers and Acquisitions on the corporate performance. The studies looking at the effects of M&As can be broadly classified into three- market measures based, accounting measures based and mixed measures based studies. From the literature review, however, it is found that there is no conclusive evidence to show that M&As are responsible for value creation for the companies and their shareholders. Moreover in recent periods M&A deals have increased tremendously. Hence there is a need to look into the post M&A performance of companies more closely to find out whether the M&A activity helps the corporations in achieving the objectives of increased efficiency and profitability in the form of value creation.

Introduction

“Corporate Restructuring refers to the changes in ownership, business mix, assets mix and alliances with a view to increase the shareholder value. It includes a wide array of activities such as mergers, acquisitions, joint ventures, spin-offs, leveraged buyouts, demergers, buyback of shares, capital reorganization, sale of business units and assets, etc.” Out of these, mergers and acquisition is the most common route taken by corporations for inorganic growth all over the world. In fact the last two decades have been known as the M&A waves.

Mergers and Acquisitions for long have been an important and routine part of companies in developed nations such as the US and UK. In India also, they have now become a matter of everyday occurrence. Every day, we find newspapers filled with news about M&A deals. “Various parties that are interested in this field include owners of business firms who are searching for potential partners to implement mergers in future, investment bankers who are responsible for managing the mergers, lawyers who provide advisory services to the parties involved, regulatory authorities that are concerned about the operations & safety of capital market and increasing corporate dominance in the economy and, academicians who want to understand these areas better”.

Mergers and Acquisitions take place when two or more companies are brought under the same effective control and are managed by the same group. It can be done in two ways: (i) acquisition of one business unit by another or, (ii) creation of a new company by complete consolidation of two or more units. For instance, Snapdeal has acquired Freecharge, Sun Pharma acquired Ranbaxy, Yahoo acquired Bookpad, Flipkart acquired Myntra, and TCS recently announced a merger with the listed CMC with itself, as part of the Tata group’s renewed efforts to consolidate its IT businesses under a single entity.

The purpose of this paper is to examine and synthesize M&A literature on the effects of M&A transactions on the financial performance of the involved companies and their shareholders’ wealth so as to identify the factors that might influence the performance, where such factors should be considered by management in decision making.

A sincere attempt has been made to review and summarize the major studies carried out in the field of Mergers and Acquisitions in India and abroad. This extensive review will be helpful in enhancing the present level of understanding in the area of mergers and acquisitions, understanding the reasons behind success or failure of merger deals and formulating the problem for further research in this field. Broadly, literature review has been done on empirical studies in journals, published papers and other useful internet material to explain different aspects such as domestic and cross- border M&As, their causes, trends etc. and the impacts of Mergers and Acquisitions on the corporate performance and shareholders’ wealth.

This paper is organized as follows: Section 2 discusses the objectives of study, Section 3 details the Literature Review on the Impacts of M&As on Corporate Performance and Shareholders’ Wealth, Section 4 presents the Critical Analysis, Section 5 contains Conclusions and, lastly References are given in Section 6.

Objectives of the Study

The major objectives of reviewing the literature are as follows:

• To have an in depth insight about the mergers and acquisitions taking place in India and across the world.

• To inspect the literature which shows the relation of M&As with corporate performance and shareholders’ wealth.

Literature Review on Effects of Mergers and Acquisitions (Impact on Corporate Performance and Shareholders’ Wealth)

Mergers and Acquisitions are important strategic decisions that affect the long term profitability and wealth of shareholders of the company. Researchers, especially in developed economies such as USA and UK have conducted numerous studies to answer the basic question: Do mergers and acquisitions create any value for the company and its shareholders? Studies focusing on the post-merger performance and value-creation effect of M&As usually follow either of the two general approaches: first is share price analysis- using data regarding share prices to identify gains and losses to shareholders of acquirer and target firms, and second is operating performance analysis- using accounting data to analyze long-run operating and financial performance of acquirers in a merger deal.

The studies falling under these two approaches can be further divided into three categories:

• Announcement period studies,

• Studies focusing on long term share price performance and,

• Studies focusing on operating performance.

This section discusses the important studies undertaken in each of the above-mentioned three categories to draw a general conclusion on the impact of M&As on the corporate performance as well as on the shareholders’ wealth.

Announcement Period Studies

Such studies follow event study methodology and consider the short term returns earned by the shareholders surrounding the announcement period of the event. Whenever there is an announcement regarding merger of two firms, the market adjusts rapidly to this information and this new information is incorporated into the share prices of firms. The returns generated by shareholders on the days around the announcement that are specifically due to the announcement of the event are called Cumulative Abnormal Returns and have been studied by the researchers to determine the gains or losses to the shareholders. A large number of such studies conclude that the target firms earn positive returns while shareholders of acquiring firms experience loss of wealth. Some important studies are as follows shows in Table 1:

Both acquirer and acquired firms lose in stock-financed transactions. Also, there is a positive effect of related or non-conglomerate
mergers on the wealth of acquiring firms’ shareholders.
Davidson and Cheng (1997) To test – (i) bid premium is greater for cash- financed acquisitions than stock-financed acquisitions,
(ii) excess returns generated to the target firms in the announcement period depend upon the bid premium and not the method of
payment.

Specifically, merger deals were more value enhancing than acquisition deals and bank-to bank deals provided higher returns to the shareholders than
cross-product deals. European market generally reacts more
favorably to cross-border mergers than to domestic mergers.

Studies Focusing On Long Term Share Price Performance

A large number of studies, using event study methodology, have been undertaken by researchers to examine the effect of M&As on the share prices of firms in the long run. Some significant studies discussing this aspect are as follows Table 2:

Studies Focusing on Operating Performance

A large number of studies based on accounting measures such as financial ratios and financial statements data have been conducted by the researchers to determine meaningful improvements in various financial measures of profitability, cash flow position, liquidity etc., resulting primarily from Mergers and Acquisitions over a long time period of time. The studies reviewed are as follows Table 3:

Critical Analysis

The researchers have conducted in depth theoretical and empirical studies in the field of Mergers and Acquisitions to identify the reasons and impacts of such activities. While a plethora of literature is available on M&As in the international context, few studies have been done in developing economies like India particularly in the financial sector.

On the basis of literature review, the studies conducted to identify the effects of M&As can be broadly divided into three categories:

(i) Announcement period studies,

(ii) Studies based on long term share price performance,

(iii) Studies based on operating performance.

In terms of the methodology, two empirical approaches namely; event study methodology and pre- and post-merger performance using accounting data, have been used in the studies conducted all over the globe.

As far as the announcement period studies are concerned, majority of them have reported significant increase in the wealth of target shareholders, while insignificant gains (or even negative abnormal returns) for acquirer shareholders around the announcement period (except Rosa et al., 2004) who have reported that shareholders of acquiring firms realize significantly positive abnormal returns on announcement of bids for private targets, Floreani & Rigamonti (2001); Asquith et al. (1983) who have shown that M&As result in an increase in the wealth of shareholders of acquiring firms).

Further, it is not clear if domestic or cross-border deals result in positive abnormal returns for shareholders. However, in Europe, the markets have reacted positively to cross-border deals rather than domestic deals (except Cybo-Ottone and Murgia (2000) who have shown that in the European banking market, domestic deals tend to create more value than cross-border deals).

The studies focusing on long run share price performance, conducted in both developed and developing nations like India have concluded that mergers and acquisitions do not result in significant wealth gains to the shareholders of acquiring firms in the long run. Specifically, acquirers financing a takeover through equity, and single (as opposed to regular) acquirers demonstrate significant negative performance.

Almost all US and Indian studies focusing on operating performance have argued that M&As are not value creating, they do not result in an improvement in post-merger operating performance of acquiring companies (except Healy et al., (1992); Cornett & Tehranian (1992) who have reported a significant increase in operating cash flows of merged firms post –merger). However, these results are not consistent with empirical studies from other economies. Malaysian studies have given positive results (see. Rahman & Limmack, 2004). Further, Australian studies have produced insignificant post-merger profitability (see. Sharma & Ho, 2002).

Moreover, all the studies reviewed have shown that cash financed M&As result in significant positive returns while stock financed deals result in negative or insignificant positive abnormal returns (except Choi & Russell (2004); Sharma & Ho (2002) and Floreani & Rigamonti (2001) who have shown that method of payment does not significantly influences post-acquisition performance). Also, it has been found that diversifying acquirers perform worse than non-diversifying acquirers (except Sharma & Ho (2002) who have shown that the type of acquisition (conglomerate versus non conglomerate) does not significantly influence post-acquisition performance).

Also, there is a unanimous conclusion in literature that hostile mergers are more likely to result in leaner, efficient and more profitable organizations as the studies reviewed have shown that the hostile bidding firms earn significantly positive returns in the post announcement period.

Conclusion

With an impressive body of research literature on M&As, it can be safely concluded that Mergers and Acquisitions are one of the most researched areas in finance. However, most studies have been done only in the efficient markets of the developed world, especially US and UK to determine wealth creation effects of mergers and acquisitions.

Though M&As basically aim at maximizing the wealth of shareholders, several empirical studies have shown that M&As benefit shareholders of target firms while shareholders of acquiring firms either fail to earn any significant positive returns or experience negative returns during post-merger period. The profitability of acquirers also decreased after mergers and acquisitions.

The reason behind the shareholders of acquired companies being benefited the most is that in majority of the cases, the acquiring company usually pays a little extra than what it should. So that the shareholders forego their shares, the acquiring company offers an amount more than the actual price prevailing in the market. This gain is larger in case of cash-financed deals because the cash targets demand greater payments from acquirers to offset their higher tax liability. On the other hand, the acquirer shareholders are most harmed. The reason behind this can be debt load, which comes along with acquisition.

In developing countries like India, very few studies have been undertaken on this hot topic, especially, limited studies have been done to examine the implications of M&As on the shareholders’ wealth. But still, there is little additional evidence coming from small or emerging economies to complement the results already established for the larger market.
