ABSTRACT

The purpose of this dissertation is to critically review the performance puzzle of mergers and

acquisitions over a past few decades, mostly on British results with minor results, covering Irish

experience. It has been seen in the recent past that, with the progression of takeover activity, the

debate over its advantageous aspects has considerably increased. However, past extensive research

has revealed that, as far as the authenticity of the fact that the transactions of M& As do create value

is concerned, there is still a doubt. This study attempts to explore the impact of mergers and

acquisitions on the bases of empirical evidences, over a past few decades, and further examine that

very fact relevant to the issues of ; value creation process and the bid resistance relationship, size and

growth, performance and profitability, and so on. For this reason, the literature review method is

being employed in this paper, and ten academic research papers, related to this topic, are being used.

After reviewing all the ten research papers, which are being selected in order to provide a

comprehensive analysis over the issues under study, it is, thus, possible to draw a conclusion that over

all impact of amalgamation activity has generated a mix results in respect to returns to the

shareholders of both the target and bidder. Along with that, there are evidences of different results,

generates from takeover activity, on the size and growth, performance and profitability, value creation

and bid resistance relationship, under different environments. However, the results obtained after

examining the different issues under observation can not be termed as a full and final verdict, since

the different techniques, methods, data sample, assumptions, and so on, have been employed in the

ten academic research papers under review.

INTRODUCTION

During the last few decades, empirical research has opened new door-ways to explore and understand

the performance puzzle of mergers and acquisitions. With the progression of take over activity, the

debate over its advantageous aspects has increased. Evidences from the past extensive research unable

to justify the validity of the fact that, the transactions from M& As activity do create value. However, it

has been revealed from most of the study that takeover activity produces two different streams of value

creation for the shareholders positive stream for target firm shareholders, where as, very often,

negative stream for acquiring firm shareholders, who often lose during acquisitions (Weidenbaum &

Vogt, 1987). Not only that, but the other issues resulting out, from the impact of M &As on; value

creation process relationship with bid resistance, size and growth, performance and profitability, and so

on, have doubted its advantageous and beneficial role at a very critical level. And this demand further

to answer that; with the existence of possible failures in the takeover process, why the firms actively

participate in the activity where one company bid for another?

As, historically, mergers and acquisitions have been considered exclusively the domain of economists,

market strategists and financial advisors; the financial and strategic aspects of the activity are well

appreciated and have been extensively addressed and debated in the management literature. The

mergers activity occurs between two companies coming together acquirer and acquired. There is a

big list of stakeholders in the company, mostly debatable identities; shareholders and managers.

Efficient and perspective managers always aim to achieve the corporate goal; Maximizing the value of

the firm subject to share price maximization. One of the main purposes of this paper is to investigate


9/81



and draw conclusion regarding the impact of takeover activity on value creation of shareholders of both

the target and bidder over few decades, based on British and Irish results.

The first wave of merger in UK strikes during the 60s and why it occurs because of the efficiency-

related reasons, for instance; economies of scale or other synergies, removal of incompetent target

management, diversification merits, elimination of agency costs. After its booming year of 1968, the

first wave of merger diminishes. During the early 1970s the merger wave started to rise again and hit its

second peak in 1972. The third was during the period of 80s and this was the period of dominance of

mergers, acquisition and other form of strategic alliances over business and financial press.

The preoccupation along with the incidents in terms of massive positive outcomes out of the

organizational marriages during the 80s made the mergers and acquisition a world wide growth

industry. However, the activity of mergers and acquisitions declines substantially as the organizations

move to downsize rather than upsize their operations. But, the managerial predictions were

suggesting that lot to be gained from M& A, and due to its persuasive and seductive appeal this activity

have gained business confidence and M& A started to pick up once again. During the period of 1993-

2000 the UK has experienced the fourth merger wave, and it has been confirm by the survey

(Catwright, Cooper and Jordon, in press) of almost 500 senior European managers of its continuity

during the period of 90s.

The process of acquisition might prove to be a useful tool for management, by taking away obstacles in

the way of achieving growth objective (Penrose, 1959).Also, the firm can get from acquisition the new


10/81



opportunities of investment and start work in a totally different business environment with working on

a new product line (Cable, 1977). It has been noticed that the mostly the takeovers have happened with

the intention of changing the whole pattern of business been transacted before by the acquired company

during the 80s and 90s.However, in 2001, UK has experienced a drastic change in the M& A activity

and its graph went down which is mainly due to the shifting of consumer interest from the internet and

telecommunications industries.

Although mergers vary by type, there have been many theories put forth to explain the general nature of

merger activity. For instance, the theory of the firm and the theory of economic "natural selection", has

given a noticeable preference in this paper to find out the implications of takeovers results over this

theory. In relation to stock performance analyses in the activity of M& A, it has been argued that, if,

capital markets are efficient enough that it can capture all the future costs and benefits of mergers and

discount them at the same time into share price, than the occurrence of long term valuation changes

cannot be related to acquisition (Sudarsanam, 2003). One can argue, the capital markets works on the

semi-strong level, which may make sense, then only after analyzing the considerable amount of years it

can revise the decision on the bases of new information about the progress of takeovers and competitor

response. However, if the stock market valued the stock prices in a way that it contains valuation errors,

then there is a possibility that the firm can be undervalued or overvalued (Scherer, 1988).This paper also

gives an insight about the stock performance activity after the deal has been completed and how it

turned up over considerable period.

With respect to empirical evidences, the purpose of this dissertation is to critically review the


11/81



performance puzzle of mergers and acquisitions over a past few decades, along with further

examination of results, thus obtain, in relevant to the issues of ; value creation process relationship with

bid resistance, size and growth, performance and profitability, and so on. In relation to returns to

shareholders of target and bidders, there are mixed kind of empirical evidences. For instance, usually,

but not always the acquired organisation is smaller and/ or less profitable than its acquirer (Singh,

1971; Meeks, 1977). In addition to that this study further provide a comprehensive insights on the

issue of value creation process during the bid period and its relationship with the bid resistance, and

the examination of failure rate of acquired firms, during the boom in mergers of U.K companies.

This paper proceeds as follows; Chapter 1 introduces the motivation and purpose of this paper. Chapter

2 describes the methodology being used in this study, which further discuss and explain the

advantageous aspect of literature review and discuss why this method has been chosen through

comparing it with other methods of event study, case study and literature review. Chapter 3 gives past

glimpse of mergers and acquisitions in U.K. Chapter 4 base on revision of ten academic articles in

order to provide comprehensive results, related to the research work, to be analysed later on. Chapter 5

involves interpretation of results from the ten articles and discuss implications issues for shareholders.

Chapter 6 summarizes conclusion and limitation, and finally, Chapter 7 represents Bibliography.

CHAPTER 2:

METHODOLOGY


13/81



2.1 METHOD AND METHODOLOGY

The word methodology is normally considered to be a branch of philosophy or logic among a wide

range of literate people, though most often some logicians termed logic being a part of methodology.

Methodology refers to the overall approach to the research process, from the theoretical

underpinning to the collection and analysis of the data. Like theories, methodologies cannot be true or

false, only more or less useful (Silverman, 1994).

Where as the method, used in educational research, refers as a different way of approaches used as a

basis for interpretation and inference for explanation and prediction either new facts or ones which

already being explained. These approaches basically are the techniques connected with the model

known as positivistic model, which includes recording measurements, describing phenomena,

drawing out conclusions out of predetermined questions, performance of the experiments. This has also

been confirmed by most of the researchers that the one should have a full understanding on the

philosophical aspect of study which is linked to his specific academic papers. Accordingly, this will

some how effects the entire piece of research work which mainly includes the activities of gathering the

required information, collecting and analysing the data, pin out the limitations and try to fill in the gaps

where ever it is essential (Hussey and Hussey, 1997).

If method, as a technique or procedure, involves a process in which there is an activity of data-

gathering, then the aim of methodology can be explained easily in the words of Kaplan:

To describe and analyze these methods, throwing light on their limitations and resources, clarifying


14/81



their presuppositions and consequences, relating their potentialities to the twilight zone at the frontiers

of knowledge. It is to venture generalizations from the success of particular techniques, suggesting new

applications, and to unfold the specific bearings of logical and metaphysical principles on concrete

problems, suggesting new formulations (Kaplan, 1973).

The five most frequently used designs or traditions of qualitative research include: (a) ethnography,

(b) grounded theory, (c) biographical, (d) case study, and (e) phenomenological (Creswell, 1998). The

percentage of importance given to one of the techniques known as qualitative is usually done through

the trustworthiness of the data related to confirm ability, credibility, dependability, and transferability

(Guba, 1981). The literature review is regard as a main method which is subjective in nature and

applies to the qualitative research. The main purpose of subjective research is to further exploration of

different prospective. Therefore, the subjectivity holds an important position in this dissertation and

should reflect through out the study.

Since it has been mentioned earlier that the philosophical position of the study is important, thus it is

essential to draw attention towards the two main philosophies Phenomenology and Positivist

paradigms. In the positivist paradigm, we get a view of an observer as an independent identity, world

considered to be external and objective, and science is termed as an unbiased or we can say it value-

free as well. On the other hand, when we study the phenomenological paradigm it gives us a view of an

observer being a part of what is being observed, world considered to be subjective and socially

constructed, and science is opposite to what we have in the positivist paradigm i.e., biased (Easterby et

al, 1996). Perhaps, for the positivistic researchers, phenomenological methodology is term as the most


15/81



controversial of all forms of qualitative inquiry which depends upon the post-modern philosophies and

interpretive techniques (Sabornie, 1994). Thus, in this paper the phenomenological paradigm is being

applied as a research method of literature review, which is subjective in nature.

Research work, in the field of accounting and finance, has three common methods Empirical

research, case study research, and literature review. Empirical study involves an activity of establishing

the relationship between the variables under observations (Ryan et al, 2002).This research work has a

motive to critically analyzing the performance puzzle of mergers and acquisition which mainly involve

the issue of its impact on; shareholders returns, size and growth, value creation process and bid

resistance relation ship, performance and profitability, and so on, over a few decades. In this regard,

empirical research and literature review method might be suitable, rather than others methods. If we

look into the previous empirical research work the most work done by the researchers is based on the

event studies under the similar context. However, event study method has some disadvantages,

specially under the assumption that capital markets are efficient, event study method happened to

evaluate the impact of events on expected future gains for the shareholders through the expected profit

of the firms. This specific study is mainly based upon the literature review method, by keeping in mind

the factors like - the empirical study might take a long time to collect data and the time barriers.

2.2 OVERVIEW OF RESEARCH DESIGN

2.2.1 THEORY OF LITERATURE REVIEW

Knowledge doesnt exist in a vacuum, and your work only has a value in relation to other people.


16/81



Your work and your findings will be significant only to the extent that they are the same as, or different

form, other peoples work and findings( Jankowicz, 2000).In preparing the research work, it is very

important to keep up the work in contact with the previous relative work.

A common misunderstanding with critical literature review is that they become uncritical listings of

previous research, often being little more than annotated bibliographies (Hart, 1998).

More over, in a broader sense literature review is said to be the summary which might be obtain from

the combination of observed facts and findings out of the literature search which is very important for

any research activity. Together, this all would helps in doing the work with in the context, along with

an intention to further understanding of the reviewed articles and shape the work in a different and

more desirable way.

2.2.2 STRUCTURE OF SEARCH

In the process of structuring the search as per requirement of the dissertation, which is mainly

comprises of reviewing books and journals, three stages are involved. At the very first stage of

compiling the dissertation work, internet facilities are being taken into consideration. Due to the

worldwide advancement in the field of technology it is now become easier to access the articles of any

kind. Also, the search engines Ask, Alta vista, Google etc, generally proves to be very vital during

the search process. Second stage involves an activity of accessing the electronic versions of the

professional journals, which are easier to access for the computer and internet users. Also, the library

services have been utilised in the best possible way, with the data bases having numerous networked


17/81



journals, which are further arranged alphabetically and by subject. Lastly, the third stage involves the

vast range of books and journal reviews and there availability in the university library. These all stages

leads towards the assurance of the suitable environment for the research work that any writer would

likely to have in order to bring about the healthier and beneficial research work for others.

2.2.3 FINDING APPROPRIATE ARTICLES

The initial search revolves around the activity of finding and reading of articles which are roughly forty

to forty five in numbers, and mostly main concern is given to the introduction and conclusion sections.

After that there comes the final selection part of the articles out of many and since this is a basic

requirement of the dissertation, therefore ten articles identified as the key literature review materials.

The selected articles have a close relevance with the research question. Despite the fact that the articles

has already been chosen however, it has been ensured that if there is a need to replace any of the

articles during the review it will be done immediately, to keep up live a readers interest in a topic.

2.3 LIMITATION

Like every research, this paper also has to go through some restrictions on its own. Like the research

method used is mainly depending upon the review of the articles, which themselves are limited in

numbers. It is quite impossible to go through all of the articles and have an in depth study in a shorter

allocated time period. The personal knowledge of a writer in selecting the specific articles for the

research work couldnt be regarded as a full and final verdict and therefore, said to have biases on some

points. Apart from that, the main motive of a writer is to work on dissertation in a most beneficial way


18/81



and to focus entirely on the main theme question with keeping in mind to provide a comprehensive

analysis and insight of a subject matter under study. It has also hoped that the work been done under

the circumstances could fulfil the part of work assigned during end of the semester and meet the

dissertation requirement thereby.

CHAPTER 3:

A GLIMPSE OF M& As ACTIVITY IN UK:

(PRE, INTER, POST-WAR PERIODS)

3.1 BEFORE 1914

During the mid of 18th

century, the comparative advantage of mergers and monopolies couldnt be

gained, due to number of reasons; despite the fact that the companies could be formed through an easy

process of registration since 1844 and in 1855 the general limited liability could be obtained, still the

massive industrial activity of that time was in the hands of few dominant business family. Even after

becoming companies they were still worked as private companies, though not in law. Up until 1914,

although there were very little takeovers movements in UK industry, the facts and figures do present

some really interesting lessons which prove to be a guide in present day amalgamation movement in

British industry.

British merger activity enjoyed the advantage of company law before 1914 which were different than

that of older English law on trusts and trustees. The process was not easy for the massive businesses to

merge into larger unit before 19th

century time due to the fact that they, unlike, modern company, did

have diffused share ownership and fewer family loyalties. Till 1930s, there was no existence of

Britains policy of free trade which affects the power of monopolist to raise prices in general and also

different industries in particular. The British coalfields were very much affected and scattered and the

family who owns the business were reluctant to have a business conversation with their rivals from

other parts of the area. Like wise, British cotton industry, which was considered to be the highly

concentrated at that time, also did not seem to adopt the combining concept as strongly agreed by the

larger proportion.

In brief, with the existence of high degree of specialization, which was giving benefit to the customers


21/81



to the different part of the world, was against the concept of standardization of product, which might

boost up the concentration level of production. However, where ever there was any success, as an

outcome through the combinations, it was mainly attached with the manufacturing or management

skills. And in the absence of these skills usually the combines happened to be a failure, which further

affect the extension process.

3.2 THE INTER-WAR YEARS

During the period of two world wars British trade industry experienced major set backs to her

important nineteenth-century industries. During this transition period of leaving war zone and

entering into the peace zone brought interruption to world trade along with that affecting some of her

major markets. Many of the companies felt considerable amount of damage caused due to old and new

amalgamations. As a result of that damaging effect many of the larger combines were declined

absolutely or where replaced by new firms in new industries.

The 1947 edition of Stock Exchange Year Book accounted that more numerous amalgamations are

interestingly less successful, out of the pre-war experiences of the major merger activity. Where as, the

term Successful here means that the steady dividends were being paid to shareholders and no capital

was written off. It has been noticed that the mostly successful mergers of firms happened in the same

business-line trade where concentration given to only process activity at a very large scale unlike

other mergers which were involved in a multitude of different activities and that might be the major

cause of their failures.


22/81



3.4 POST-WAR YEARS

The post-war period, since 1945, happened to be totally different for businesses if we economically

examined and compared the background conditions of the amalgamation movements. Second World

War caused greater damage and disrupter to the economy as far as financial aspects of businesses were

concerned. The period of post-war readjustment mainly was dealing with the environment of very

changed circumstances of shortages; financial controls; and massive loss of businesses in overseas

markets. Some of the industries has faced decline in there businesses not because of general trade

depression but due to the fact that the larger portion of their older customers have developed a taste for

a new product. However, by considering the previous European Wars Thirty Years War, the

Napoleonic Wars and the First World War, one might conclude that Britain economy made remarkable

recovery.

The business conditions during the post war period have been easier and more profitable as compared

to pre war. The Government followed the Keynesian Revolution of full employment and expansion

policy which results in the higher profits, generates through the activity of higher consumer demand

which results in higher sales to producers and than profits. Apart from the symptoms of monetary

inflation started to appear, there has a considerable amount of economic growth been recorded in real

terms with the surety of higher living standards as compared to other countries. But one can not

overlook the fact that main cause of economic progression in UK industry is because of the

management efficiency arising from the mergers. It has been noticed that the companies having

superior top management tend to generate huge profits for the shareholders.

4.2 LITERATURE REVIEW OF ARTICLE # 1

J. R. Franks; J. E. Broyles; M. J. Hecht (Dec., 1977), An Industry Study of the Profitability of

Mergers in the United Kingdom, The Journal of Finance, Vol. 32, No. 5., pp. 1513-1525.

4.2.1 PRINCIPAL PURPOSE OF RESEARCH

Franks, Broyles and Hecht (1977) work mainly have two purposes; prime purpose is to gather the

information about any gains and losses to shareholders from the behavior of share prices in the U.K.

Stock Exchange Market, from the mergers activity in Breweries and Distilleries industry. Secondary

purpose is to further asses and draw conclusions, if any, from the gains and losses pattern of the share

holders of both the acquirer and acquired firms, out of merger and acquisition activity. In addition, this

paper also gives an insight about the level of efficiency of London capital market, and how the

forthcoming information about the mergers influences the pricing pattern of equities.

4.2.2 BRIEF DISCRIPTION OF METHODOLOGY AND DATA

During the period 1955-72, Franks, Broyles and Hecht (1977) examines the abnormal gains for

shareholders of both the acquirers and acquired companies involved in the mergers in the U.K.

Breweries and Distilleries sector, out of the sample obtained from the Daily Official List of Stock

Exchange, London. They have chosen the standard market model, which is the most common and

widely used as an event study model. There is a hidden benefit in using the market model - it helps in

reducing the effect of variance of abnormal return which makes it possible to detect event effect more


27/81



effectively (Dasgupta, Laplante, Mamingi 1998). The study construct an effective announcement dates

from t = -40 to t = 40 as a time reference.

The researchers make adjustments into the original Fama, Fisher, Jensen and Roll (1969) method of

calculating abnormal stock market returns in response to the public announcement. As well, other

adjustments and alterations also being applied like - there were 94 mergers available in the industry,

during the period of 1955-72, which was reduced to 70 mergers due to the lack of adequate

information; fixation of the double counting of the pre-mergers interest to the shareholders; treating the

17 holding companies as a acquirer after the merger; adjustment of non-trading effect arose due to

the combination of the thinness of trading together and unreported transactions; and because the

London Business School Data Base was still in the process of compilation during the work, alternative

ways were adopted in creating the market index.

4.2.3 MAIN RESULTS

Franks, Broyles and Hecht (1977) reveal that there are hardly any gains to acquirors shareholders

during the months subsequent to mergers. However, the Cumulative abnormal returns (CAR)s of

acquirees fall, during the months t = -40 and t = -15 and relatively less profitable than the acquirors

during this period.

The time period between t = -15 and t = -4 proves to be beneficial to acquirees and it rises to 5% as

compared to the acqiurors (CAR) which remains unchanged. Apart from that, acquirees (CAR) rises


28/81



up to 26% by the t = 1, approximate offer date as compared to acquirors (CAR). This will suggest that

the acquirors shareholders havent gained substantially well, as expected; also it shows the strong

anticipation of the market just 3 months prior to actual announcement date, to anticipate the merger

event on average. There is a gain recorded to the acqiurors shareholders during the time of merger

reflect nothing but the readjustment pattern behavior of London Stock Exchange market, which is

consistent with the results of Kaplan and Roll (1972).

Franks, Broyles and Hecht (1977), also examines the economic benefit to shareholders by combining

the results of (CAR) of acquirees and acquirors shareholders. According to them, the period of t = -4

and t = +1, which is a period where the market was very much likely to respond to the event of merger,

they have recorded a gain of 0.10 which is non-the-less shows smaller abnormal gains.

4.2.4 CONLUSIONS

Franks, Broyles and Hecht (1977), notice that the shareholders of the companies involve in the merger

activity in U.K. Breweries and Distilleries sector has experienced a net gains. Apart from some

temporary positive gains for shareholders of acquiring companies, it has been observed that the

Perfectly Competitive Acquisitions Markets Hypothesis is consistent with its hypothesis that the all net

benefits are for the acquirees shareholders in the merger activity. Also, the U.K. capital market

observed to be consistent with the Efficient Capital Markets Hypothesis and able to reflect fully the

relevant information in capital market prices.

Michael Firth Takeovers, Shareholder Returns, and the Theory of the Firm, The Quarterly

Journal of Economics, Vol. 94, No. 2. (Mar., 1980), pp. 235-260.


Firth (1980) work mainly base upon to report the results, out from the impact of takeover activity, on the

wealth of shareholders, in the U.K. The researcher work is different in a sense that it takes into

consideration the theory of firm in drawing out the results. The paper also takes in to consideration the

behavioral motives of takeovers and examines by briefly reviewing the empirical evidence to date in

U.K. and U.S.A.

It is also evident from the recent research that the profitability generates from the monopolistic factors

and through implementing the sound base of superior management in acquired firm (Manne, 1965). Due

to that fact, the considerable portion in millions of pounds has been invested to take a charge of

companies in Britain. Firth (1980) also examines the gains to shareholders, generates out of the returns

from the securities they have invested, and the benefits to management, if any, during the mergers and

acquisitions process.


Firth (1980) examines the data of the bidders and targets firms listed in stock exchange market during

the period of 1965-75 and, summarize results on the basis of the successors and failures during the


30/81



process of takeovers. The researcher concludes that bids out of 486 targets and 563 bidders, only 355

bids were successful; after the revision session of bids 79 bids termed as successful; and 52 were un-

successful.

Firth (1980) uses the market model relationship, in-order to draw the result of expected return, as

suggested by Sharpe (1963). Where as the shareholders wealth effect consequent to takeover is

measured adjusting the actual returns on a security against those returns which are expected, incase if

there had been no takeover activity happened. i.e.

Uij = AR jt -ERjt,

Where,

Uij = residual for securityj in time t.

AR jt = actual return on securityj in time t.

ER jt = expected return on securityj in time t.

The study consider the relationship i.e.ER jt = j + jRMt for estimating the period

covering last 48 months with the exclusion of period 12 months prior and subsequent to the takeover bid

months in order to account the shifts in the risk of parameters (Mandelker, 1974). In order to capture

the shifts in the risk parameters in the context of pre and post-period of bid announcement, following

dummy regression is run;

Rjt = aj + a jDt + bjRMt + b jDtRMt + ejt


31/81



The Dummy variable Dt, is set equal to zero for the period month -48 to month -13, and, set equal to

one, for the period +13 to month +36.Moreover, in-order to find out the impact of takeovers process

over the security returns average residualsAR and cumulative average residuals CAR being used.

Firth (1980) follows the same methodology, which being used in driving the results for the takeovers

activity in USA during that period by Mandelker (1974), Ellert (1976), Dodd 1976 and Ruback (1977)

and Kummer and Hoffmeister (1978). This helps the researcher to solve the hidden problem of

overlapping results getting from the test statistic of average monthly residuals of securities by simply

constructing portfolios of securities and calculating standardized portfolio residuals.

4.3.3 MAIN RESULTS

Firth (1980), find out some very interesting results related with offeree firms; up until one month left,

for the merger activity to be happened, the portfolio t-statistics shows insignificant results in term of

evidence of any abnormal share price behavior; during the last month i.e. -1 the t-statistics shows

significant results and there is a sharp up ward movement of roughly 80 percent in gains of sample

securities; and substantial gains being recorded in 99 percent of securities during the bid announcement

period. Furthermore, positive residuals during the period month +13 to month +36 shows that the gains

exists during the 3 years after bidding announcement, even though the takeover deals was a failure.

This also gives an indication of an efficient market behavior; unbiased estimation of the future returns

to security holders in response to the initial movement in the share price.


32/81



Firth (1980) evaluates that there is no abrupt activity in the abnormal gains to bidding companies prior

to bid announcement unlike to American research findings by (Dodd, 1976 and Ruback, 1977). During

the month 0, there was negative activity recorded in residuals out of 80 percent of securities for bidding

firms proves costly to them. However, after a year to the bid announcement, the positive residuals show

stock market takes a failure bids as good news and as a result there are positive gains to unsuccessful

offerors.

Firth (1980), also indicates that there is no gain no loss situation existed during the mergers activity in

Britain in the period 1969- 1975, simply because the gains of offeree firm are being directly cancelled

out by the losses made to the offeror firm. However, as far as benefits to management are concerned, a

regression analytical test has been carried out which shows a positive results for management of

acquiring firm even though the takeovers result into failures or losses to shareholders.

4.3.4 CONLUSIONS

Firth (1980) notices that the merger and acquisition activity in U.K proves to be beneficial for acquired

firms shareholders and acquiring firms directors. However, in contrast to that the acquiring

companies shareholders suffer substantial losses and that proves to be a risky business for them. As far

as stock market is concern, it views the takeovers activity merely adds into the corporate profitability,

and that the takeovers significantly reduce the value of acquiring firm.

Louis C. Murray A Study on the Wealth Effects of Irish Takeovers and Mergers, Managerial

and Decision Economics, Vol. 12, No. 1. (Feb., 1991), pp. 67-72.


Murray (1991) evaluates the share-price effects of mergers and acquisitions activity on the Dublin

Stock Exchange based upon the findings of an empirical study. The main purpose of the study to find

out that whether the results of returns from the shareholders on the Dublin Stock Exchange similar to

past expected pattern of returns to biding- target-company shareholders from acquisition activity (e.g.

Jarrell et al., 1988 and Jensen and Ruback, 1983). This research paper also has an insight over the

market in-efficiencies behaviour during the acquisition period of 1965-83.


Murrays (1991) work mainly covers the data over the period 1965-81 in which it is make sure that

both the acquirer and acquiree will be quoted. Due to that fact total number of recorded acquisitions of

quoted companies resulted to be 45, out of which 40 mergers and acquisitions are taken into

consideration because the 5 companies were not actively traded on the exchange. The researcher

follows the Dodd (1980) method of designing the data; base data comprises of initial announcement

dates of the acquisitions, where as dates are being identified through daily study of financial pages of

Irish national newspapers. It has been ensured that the data of share-prices for each of acquiror and


34/81



victim should represent, before and after, of acquisition year.

Murray (1991) constructs the study pattern of his work by taking pre-event performance period of the

acquiring firms to assess the effects of acquisition, unlike proposed by (Magenheim and Mueller,

1988), who proposed longer post-acquisition period and found cumulative net losses over a three-year

period. With the existing imperfections in the Irish market as notified by OBrien (1982), the standard

market model is being rejected, which may cause bias in the estimates and instead the weighted-least-

squares version of the model is being applied as suggested by Scholes and Williams (1977); and Marsh

(1979) .i.e.

Rit /T = ai * T + bi * Rmt /T + e`it

Where as,

T, represents the square root of the trade-to-trade interval; and e`it,represents the relation eit/T.

Murray (1991) estimates residuals by taking into consideration the technique adopted by Fama et

al.(1969) of using exclusion period comprises of 25-weeks, and estimate the parameters separately out

of pre and post-merger data, following a work of Firth (1980). Furthermore, the t-test statistical

approach being used in order to get values from average and cumulative average residuals.

4.4.3 MAIN RESULTS

Murray (1991) finds out that the results of the victim firms do indicate random price fluctuations upto

week -20, having a similar pattern as confirmed in both American based study by Langetieg (1978) and

British based study done by Firth (1979). Moreover, the indication of strong upward movement in


35/81



share prices, made by the residuals for week -6 to -3, is nothing but a reaction to the forthcoming bids.

As well, the significant results of remaining residuals from t-test strongly recommend that the Dublin

Stock Exchange is efficient in relation to successful takeover bids. There is an indication of 30 percent

excesses points of net gains for the shareholders who maintained their holdings upto two years.

Murray (1991), however, find out that the results of the acquiror indicating a pattern of normal price

fluctuations even beyond week -10, except that of only two readings in weeks -39 and -23, which later

on turned down with the assumption that they could be related other than the acquisition activity. There

is also an indication of strong market anticipation about a forthcoming event during the week -6 and -2,

which possesses the large +ive and ive significant residuals respectively. Where as, during the post-

announcement periods, the average residuals from week +26 to +28 indicate an increase in the share

values.

4.4.4 CONLUSIONS

Murray (1991), concludes that the tendency of Irish market, in anticipating the forthcoming events of

takeover bids, is marginally slower as compared to its larger neighbours i.e. London Stock Exchange

markets and New York Stock Exchange markets. However, there is a similarity in the results; concern

with increasing pattern of victim company prices; and, that of excessive positive returns prior to formal

announcement of bids, as reported in earlier studies (see Jarrell et al., 1988; Bardely, 1980: Dodd,

1980; Firth, 1979, 1980). Where as, there is a lesser activity being recorded in connection with the

performance behaviour of acquiring companies, as a result of takeovers. Briefly, on average, the


36/81



evidence, regarding the performance of both the acquiror and victim company, suggests that the

mergers do posses value enhancing effect.

Danbolt, J. (2004), Target Company Cross-border Effects in Acquisitions into the UK European

Financial Management, Vol.10, No.1, 2004, 83 108.


Danbolt (2004) evaluates new evidences on the abnormal returns pattern for the targeted shareholders

involved in the cross-border and domestic acquisitions of U.K firms. In addition to that, the research

mainly involves in finding out any link between the cross-border effect and the different characteristics

of domestic and overseas acquisitions. Moreover, the factors like; international risk diversification,

market access, exchange rate effects, and managerial, are being investigated in relation to abnormal

returns from take-over activity.


During the period 1986-91, Danbolt (2004) examines the abnormal gains for shareholders of the

acquirer and companies involve in the domestic and cross-boarder mergers activity in the U.K. The

data comprises of 116 cross-border and 514 domestic takeovers bids on or after the 1 January 1986 and

end of December 1991. The researcher consults to Acquisition Monthly, in order to have every single

kind of information that one can get, involved in the takeover activity and proves to be beneficial for

this paper. Along with that, for exchange rate data, the researcher consults to the Datastream, and for

data on weather the acquiring companies involves in EU operation before the acquisition, sources like


38/81



company accounts, Datastream, Gloable Access, Extel, Financial Times, Sequence are being searched.

Further more, London Business School Risk Measurement Service and London Business School Share

Price Database are also being consultant along with other sources mentioned before.

Danbolt (2004) chooses three conventional models and two sized-adjusted benchmarks models, who

have an ability of giving results through observing common size effects in the return generating

process, as revealed by past researchers (see Kennedy and Limmack, 1996; Gregory, 1997; Higson and

Elliott 1998). For this purpose, Index, Market, and Capital Asset Pricing model are being used as a

three conventional models, where as, Size-deciles control model and Hoare-Govett small companies

model are being used as a size adjusted models.

Danbolt (2004) analyses the pattern of share price performance of both the domestic and overseas

acquisitions, subsequent to the bid, over a period from month t-8 and t-5. Cross-sectional t-test

technique is being used in order to test the significant level of equally weighted cumulative abnormal

return; and, mean t-test involving two sample difference method, is being used to test the differences in

the domestic and overseas acquisitions abnormal returns.

4.5.3 MAIN RESULTS

Danbolt (2004) obtain interesting results related to abnormal gains to both the cross-border and

domestic target shareholders during the takeover period of 1986-1991. The researcher observes that

UK targets shareholders in domestic transactions poorly performed, over all, as compared to


39/81



shareholders of target firms involved in overseas mergers.

Danbolt (2004) finds out that, the UK listed companies targeted in 514 domestic acquisitions, having

negative abnormal returns in every month from t-8 to t-3. However, there is an indication of positive

abnormal gains accrue to target shareholders in domestic UK acquisitions, during the month t-1. The

abnormal gains further increases to 20.29% (with the market models), during the bid month. Briefly the

overall indication from the pre and post bid period indicate the significant amount of returns for target

shareholders in domestic U.K. acquisitions, and certainly during the bid announcement month.

Danbolt (2004) also finds out that, UK target companies in 116 cross-border acquisitions into the UK,

also under perform in the very month from t-8 to t-3. However there is an indication of abnormal

returns both prior to two months and in the bid announcing month. Further more, differences in the

average abnormal returns to shareholders, in both the cross-border and domestic acquisitions,

significantly under perform during pre-bid period, and even in the bid month the abnormal gains are

very small. More over, there is an attributed impact of effect of cross border acquisition that forms a

linkage with the different characteristics (i.e currency strength of foreign acquiring firms, the mode of

payment in bid, etc.) of domestic and overseas acquisitions.

4.5.4 CONLUSIONS

Danbolt (2004), concludes that during the pre-bid period, target shareholders in both the domestic and

cross-border acquisitions, poorly performed in terms of abnormal gains expectations. However, there is

an indication of significant abnormal profits for both of the targeted shareholders during the month of


40/81



the bid announcement. Moreover, he concludes that there is an indication of existence of relationship

between the effect of cross border and effects of modes of payment, during the takeover period under

consideration.

Peter Holl; Dimitris Kyriazis (1997) Wealth Creation and Bid Resistance In U.K. Takeover Bids

StrategicManagement Journal, Vol. 18:6., pp.483 498.


Main purpose of the study, as purpose by Holl and Kyriazis (1997), is to further investigate the

relationship between the determinants of wealth creation process and bid resistance in successful

takeover bids. They proceed on, by considering the UK corporate environment, and do hypothesis over;

the agency conflicts; and the role of corporate governance mechanism in order to overcome the

conflicts. The researchers also investigate the presence of various synergies and the conflict arises

among management and shareholders, as a result of takeover activity.


Holl and Kyriazis (1997) investigate the determinants of wealth creation and bid resistance and interpret th

relationship between them, with sample covering 178 successful take over bids in Britain. They construct th

data from both the primary source - Investors' Chronicle, Mergers and Acquisitions Monthly, Mergers an

Acquisitions International, London Share Price Database (LSPD), Datastream and Extel cards; and, th

secondary source published studies of Holl and Pickering (1988), Parkinson and Dobbins (1993) an

Limmack (1991).


42/81



The work approach has been summarized into three different features;

1. Mood, being a response to the bidding company, taken as a key management decision, and thewealth accruing to the target firm, as a result of the bid is being accepted, taken as a key

performance indicator.

2. Work is being considered with in the context of past work done by Porter (1981), and Rumelt etal. (1991) Markides (1993), Mueller (1994), Seth and Thomas (1994).

3. By considering and investigating the behaviour of variables, together and on their own, asmutually dependant variables and develop the equation system in simultaneous way in order to

get the richest insight (i.e. considering the separate equation of mood and wealth being a

function of each other).

Moreover hypotheses are developed in order to further explore the fact that the synergy (operational,

managerial and financial) effects of takeover bids are a function of the principal-agent relationship and

the corporate governance system. Following are the types of hypothesis being constructed under two

different contexts;

In the context of wealth creation accruing to the target firm;

W1, hostile bids, as compared to friendly ones, will be associated with high returns (see Walkling,

1985; Datta et al.,1992), W2, higher target returns for the related mergers than un-related once, W3,

well-managed bidder firms takeovers poorly managed target firms (see Lang et al.,1989), W4,

managerial alignment inter-linked with the low levels of managerial share ownership, and managerial

entrenchment interlinked with higher levels (see Stulz, 1988), W5, negative relationship between large


43/81



shareholders and wealth creation (see Shleifer and Vishny, 1986), W6, wealth creation after takeover is

inversely related to size of bidder holdings in the target firm (see Stulz et al., 1990).

And, in the context of Mood, being a response of target management to an offer;

M1, inverse relationship between bid resistance and bid premiums (see Walkling and Long, 1984),M2,

target management prefer related bids over unrelated once, M3, inverse relationship between

managerial holdings in target firms and bid resistance,M4, large shareholdings are significantly related

to bid resistance, M5, inverse relationship between bidder holdings in target firms and bid resistance

(see Walkling and Long, 1984), M6, positive relationship between amount of debt in the bidder firm

and bid resistance.

Holl and Kyriazis (1997) adopt a model that determines response of management to takeover bid,

and, effect of the bid on the long run performance of the firm. Model is comprises of two equations of

mood and wealth which posses endogenous, predetermined and control variables;

Wealth = f (MOOD, INDFIT, VALR, TDIRSHR, TDIRSHR2, LRGSHR, BTOEHOLD,

LSIZE, CYCLE, SINGLE, CASH, OUTLIER)

Mood = f (WEALTH, INDFIT, TDIRSHR, LRGSHR, BTOEHOLD, GEARDIF,

LSIZE, SINGLE, CASH)

Where as;

MOOD = W1, WEALTH = M1 , INDFIT = (W2,M2), VALR = W3, TDIRSHR = (W4,M3), LRGSHR =

(W5,M4), TDIRSHR2 = W4, BTOEHOLD = (W6, M5), GEARDIF = M6, LSIZE = relative size of the bidder


44/81



and the target company, CYCLE = measuring the economic activity, SINGLE = measure the effect of

multiple bids, CASH = payment made in cash, OUTLIER = solving outlier problem in the data.

4.6.3 MAIN RESULTS

Holl and Kyriazis (1997) find that there are significant gains for both the target firms and the bidders of

roughly 3.1 percent; 21.6 percent excess gains for target, and, 137.1 to 139.5, i.e. 2.4 percent excess of

gains for bidders, during the month -1 and bid month respectively. The overall results from hypothesis

for wealth and mood equations are mixed;

From the wealth equation point of view - it has been revealed that there is a wealth creation activity

being observed for the target firms through the bid resistance behaviour of management, there is a

strong indication of existence of managerial synergy, with out any evidence of operational and

financial synergies, and, the indication of strong monitoring behaviour by large shareholders.

From the mood equation point of view it has been observed that the expected wealth gains process is

positively related to bid resistance, there is a liking behaviour of target management for the

conglomerate bids, and, the personal managerial independence lemmatized due to the existence of

relationship between the bid response and both the leverage levels in bidder firm and managerial equity

in the target firms.

4.6.4 CONLUSIONS

Holl and Kyriazis (1997) structured their work by modelling the determinants of, and relationship

between, wealth creation and bid resistance, on the basis of sample of successful takeovers bid in U.K.


45/81



They conclude that there is a direct significant impact of bid resistance on wealth creation process,

along with the indication of positive gains for the target firms on the bid resistance in the mood

equation. As far as, existence of various synergies is concerned, there is a strong indication of presence

of managerial and financial synergies, along with an exercise of a strong monitoring done by large

shareholders.

Ajit Singh (Sep., 1975) Take-overs, Economic Natural Selection, and the Theory of The Firm:

Evidence from the Postwar United Kingdom Experience The Economic Journal, Vol. 85, No.

339.,pp. 497-515.


Singh (1975) work has two main purposes; prime purpose is, inclusive to boom in an activity of

takeovers between 1967 and 1970, to examine the way of selection procedure of amalgamation activity,

under the ever-changing economic condition, during the post-war period in U.K. Secondary purpose is

to further examination of the results implications for; assessing the mergers efficiency in establishing

the resources in an economy; and, for the theory of firm and theory of economic natural selection, by

considering the entire period of 1955-70.


Singh (1975) construct a data comprises of all quoted companies in four U.K. manufacturing industries

during the period 1963-70. The source of data is the Department of Trade and Industrys standardised

accounting records.

Singh (1975) designs his research by comparing the records of both the categories, of the acquiring &

takeover firms and surviving and takeover firms, to find out natural selection of takeover process.


47/81



Further more, the care is taken that the records of both of the categories must be compared on both the

univariate and multivariate basis.

Singh (1975) also uses different variables for each of the quoted firms in a data over a different time

intervals, which either individually or in combination may influence a firms probability of being

acquired. These can be summarized as; Profitability, change in profitability, growth, liquidity, gearing

ratio, and size.

4.7.3 MAIN RESULTS

Singh (1975) obtain interesting results about the characteristics of takeovers and surviving companies

during the period 1967-70 and further compares it with the 1955-60s. He finds; under univariate

analysis - the takeover activity is faster in 1967-70 as compared to 1955-60, further more multivariate

analysis over a results of 105 different combinations of variables also helps in reducing the

misclassifying probability effect of a firm, as taken over or surviving, up to 3%. More over, results

from the 1967-70 are similar with the 1955-60 in terms of the probability of acquisition of firms

declined with the increase in the size of the firm.

Singh (1975), under profitability deciles category, also finds the firm that falls in three lowest

profitability deciles, have one and a half chance of being taken over, during the 1967-70, and it is found

to be very close with the over all pattern of 1955-60. How over the characteristics of acquiring and

acquired companies during late 1967-70, in terms of size, growth, profitability, liquidity, is much better


48/81



as compared to 1955-60. In terms of improvement in profitability during the period 1967-70, acquiring

firms shows slight incline in the profitability graph, where as acquired company shows decline.

Singh (1975), finds out that the takeover mechanism is more related to size than that of profitability. In

the larger organization, takeover process encourages salaried managers to concentrate on size aspect of

the firm rather than the profitability maximization. This is why takeover mechanism has a lesser

support for the theory of economic natural selection. Further more, the researcher also observes that

profitability of amalgamating firms relative to their industry average seems to decline.

4.7.4 CONLUSIONS

Singh (1975), after investigating the data comprises of all quoted companies in four U.K.

manufacturing industries for the years 1963-70, concludes that, although the acquired and acquiring

firms are different in characteristics, but a considerable amount of overlapping do exist between taken-

over and acquiring firms. Moreover, there are evidences of a weaker discipline in taking over activity,

along with the fact that mergers activity seems to have a negative impact on the profitability. In brief,

for larger firms, the study does not seem to support the theory of economic natural selection, rather

than seems to support new managerial and behavioural theories of firm.

M. S. Kumar (Mar., 1985) Growth, Acquisition Activity and Firm Size: Evidence from the

United Kingdom The Journal of Industrial Economics, Vol. 33, No. 3., pp. 327-338.


Kumar (1985) evaluates new evidences on the relationship between size, growth, and acquisition

activity of some 2000 quoted companies in United Kingdom, during the period of 1960-76. The main

purpose of the research is to study the relationship between size and growth, by using various variables,

and give comprehensive evidence on it. The distinctive part of the work is that the data period, under

investigation, hasnt been systematically considered before this search work. The secondary objective

of the study is to get the results from the relationship between the size and growth by acquisition.


Kumar (1985) obtains the data from the Company Accounts Data-bank in Cambridge, which is regard

to be the best source of information provider on U.K. quoted companies. Due to the vast merger waves

in the 60s and early 70s, the data is left with the small proportion of the firms, which is, further, divided

over three sub-periods; from 1960-65 , population I consists of 1747 firms, from 1966-71, population II

consists of 1021 firms, and from 1972-76, population III consists of 824 firms. The variables for each

firm, under the Size measures and Growth measures, comprises of ; Net Asset, Physical Asset,

Equity Assets, Employees, Sales, Total Growth, Growth by acquisition respectively. Where as, Law of


50/81



Proportionate Effect (LPE) is being used as the standard model under this framework.

Kumar (1985), adopts the OLS method technique in order to find out the systematic relationship

between the firm size and growth. The researcher obtains main results for growth, after estimating the

following equation, by using OLS method;

Log (Si, t / Si, t-1) = + log Si, t-1 + log (Si, t-2) + it

Where as;

S, represents the size of the firm, t, represents time period of 1976,t-1, representstime period of 1971,

t-2, represents time period of 1966.

For examination of effect of size on growth by acquisition, following equation is being constructed;

(A)i,t = + log Si,t + (A)i,t-1 + i,t

Where as;

Si,t, represents firm size in 1966 or 1972, (A)i,t, represents acquisition growth over the period 1966-71

or 1972-76, (A)i,t-1, (A)i,t-1,represents acquisition growth over the period 1960-65 or 1966-71.

And, for the size-acquisition relationship, equation fitted is of the following form;

(A)i,t = + log Si,t + i,t

Si,t, represents firm size in 1960, 1966 or 1972, (A)i,t, represents acquisition growth over the period


51/81



1960-65, 1966-71 or 1972 -76.

4.8.3 MAIN RESULTS

Regarding growth-size relationship, Kumar (1985), after fitting the equation on the population of the

firms surviving during the period 1960-71, and 1966-76, finds out that there is an indication of

negativity of the co-efficient on opening size, during the earlier period, which is different in results to

that work done by Singh and Whittington (1975). One of the main arguments, in this regard, is put

forward by Ijiri and Simon (1977), is the difference in persistence growth level rate between acquisition

and internal growth. The researcher also finds out even if there is no indication of increase in the

capital/labour ratio of larger firms, but they do posses growth rate in sales, over an observed period.

Where as, for the smaller firms, there is a faster growth rate recorded in both employment and capital

employed activity.

Regarding the effect of growth-size by acquisition is concerned, Kumar (1985) finds that there is a

positive relationship between acquisition and size during period 1960-71, but, a negative one during the

period 1966-76. He also finds out that the firms engaged in the manufacturing industry having negative

size-acquisition relationship.

Regarding the size-acquisition relationship, Kumar (1985) finds that there is negativity exists in the

relationship between the size and acquisition among the non-manufacturing firms, for first two periods,

where as, a week negative relationship among manufacturing firms. Further more, there is evidence of


52/81



over all uniform growth rates for larger firms as compared to smaller firms.

4.8.4 CONLUSIONS

Kumar (1985) concludes, after investigating the data of over 2000 quoted companies in Britain over a

period 1960-76, that, firms engaged both to manufacture and non-manufacture industry, having a mild

negative growth tendency related to size. There is also an evidence of persistence week relationship

between the size and growth by acquisition only for the firms in manufacturing sector. Furthermore,

there is low level of persistency in acquisition growth being found as compared to the total growth,

with the existence of inverse relation ship between firm size and acquisition growth.

Andrew P. Dickerson; Heather D. Gibson; Euclid Tsakalotos, The Impact of Acquisitions on

Company Performance: Evidence from a Large Panel of UK Firms Oxford Economic Papers,

New Series, Vol. 49, No. 3. (Jul., 1997), pp. 344-361.


The main purpose of the work of Dickerson, Gibson and Tsakalotos (1997) is to evaluate the impact of

merger on companys performance, by using the data of UK-quoted companies, involved in merger and

acquisition activity from 1948 to 1977. Another purpose of this research paper is to examine the pattern

of growth trend in terms of returns for shareholders in an activity of mergers and acquisitions by keeping

in view the takeover activity at a record bases in the recent past. Further more, this paper also shed some

light on profitability issue by examining differential returns to internal growth and acquisition growth.


Dickerson, Gibson and Tsakalotos (1997) hypothesize the effect of mergers and acquisitions on the

performance of acquiring companies. They have chosen the large panel data of UK companies over a

longer period to observes firms involves in merger process of before and after acquisition activity. The

process mainly involves by comparing acquirers with both non-acquirers and acquiring companies,

where the sample period posses the recession and boom of acquisitions.


54/81



The divided information about the each firms sample is the Cambridge/DTI Data bank of annual

company accounts (File I: 1948-77) which consisting of the large sample of UK-quoted companies .

After introducing new requirements to firms, to be quoted companies, in 60s and 70s, the researchers

have to cut-down the sample and many small companies short-listed from the list. Hence, 2,941

companies being left in the data of over a duration of 30 years, out of that 21 percent made at least one

acquisition with roughly an average of 2.35 per company.

In-order to calculate the profitability performance of the sample firms, as measured by its rate of return

on assets, following relation ship is used;

it = it-1 + jSIZEjit + LEVit +(L)Git + i + t + it

Where as;

it, is the profitability of company i in time t,, captures the degree of persistence in profits,LEVit, is

the debt/net assets ratio, (L)is any delay effect of company growth on performance, Git is a growth of

net assets, i, is company effect, t, time-fixed effects, SIZEj,represent dummies for firm size.

Dickerson, Gibson and Tsakalotos (1997) determine the impact of acquisition in two different stages. In

the first stage they include simple shift dummy (A

it), which determines the permanent effects resulting

from acquisition. Three regressions are being applied; to record the rate of return of acquirers relative to

non-acquirers, to examine the effect on the mean rate of return for firm specific effects and that of time

specific effects. More over, (AGit) i.e. acquisition growth, and (IGit) i.e. difference of total actual


55/81



growth and acquisition growth, indicate the impact of merger on profitability during the takeover period.

4.9.3 MAIN RESULTS

Dickerson, Gibson and Tsakalotos (1997) find that the re is a diminishing effect of acquisition on the

company performance during the amalgamation period in UK. There is a non-linear relation found to

exist among the profitability and the size, along with the indication of a negative influence of debt on

profitability. It has also seen that there is a positive relation ship exists between growth and profit i.e.

higher growth leads to higher profits.

In examining the impact of acquisitions on profitability, resulting out of the basic model, there is a clear

indication of lower rate of return on assets of acquirers as compare to assets of non-acquirers. For

acquires there is over all reduction in the rate of return by 2.90 percent points per annum relative to non-

acquirers, where as 17.14 percent in gains being recorded for the non-acquirers. Moreover, when the

acquisition impact on the profitability is being considered through two different prospective i.e.

acquisition growth and internal growth, the combine effects of both of them is turned to be negative,

with the lower profitability of 1.86 percentage points of over all acquisition impact.

4.9.4 CONLUSIONS

Dickerson, Gibson and Tsakalotos (1997) work is considered to be the first study ever done during that

period in which the data of the large cross-section of UK firms is being used to examine the impact of

acquisitions. They conclude that there is no, rather, detrimental beneficial effect of acquisition on the

company performance as measured by profitability, after the acquisition, by comparing the previous

performance of the companies with that of non-acquiring firms. They also agreed with the results of

some American based studies, which suggest that, when measured by profitability, mergers activity fails

to enhanced performance of the company. Moreover, even with the record level of takeover activity in

London equity market being witnessed, the findings suggest a long term negative effect on profitability

in the U.K.

Michael Firth (1978), Synergism in Mergers: Some British Results The Journal of Finance, Vol.

33, No. 2., pp. 670-672.


Firth (1978) examines the impact of mergers and acquisitions on various synergies, during the period of

1972 to 1974, in Great Britain. The main purpose of the work is to investigate the test for synergism in

mergers, by replicating the methods of Haugen and Langetieg (1975), on British merger data.


Firth (1978) construct a data comprises of 150 mergers in U.K. during the period 1972-74. The

distinctive part of the data is that - all the acquired and acquiring firms, involved in 150 mergers, were

quoted on the British United Stock Exchange; consideration done on the bases of equity exchange; and,

both of the kinds were not involved in else where mergers activity during 48 month period of takeover.

Further more, the researcher also match the non-merging quoted firms with the merging firms and

construct a control group, in which firms are mainly of same size and industry.

Firth (1978) designs his research by following the approach of Haugen and Langetieg (1975), to find out

whether there is any hint of change in a activity, which generate returns to merging group and the

control group, and if, the changes of one group is different from the other one.

Firth (1978) constructs the pre-merger period (month 1 to 24) and post merger period (month 25 to 48)

for both the merger group and control group and uses the security returns generating process, as a

market model, purposed by Sharpe (Jan, 1963);

j = j + jm + j

j, expected return from the securityj,m, market return.

4.10.3 MAIN RESULTS

Firth (1978) examines the tests which have revealed that there are no significant differences in the return

generating process for both the groups in observatory data comprises of 150 mergers in U.K. Further

more, the lack of significant differences between the control and merger, in terms of changes

occurs, is consistence to that of result construct by Haugen and Langetieg on American data.

Firth (1978), also carries out additional tests, based on the same pattern of work of Haugen and

Langetieg (1975), in order to examine the possibility of abnormal discrepancies, if exists, in the values

ofand, and finds no significant differences between the merging and control group results.

4.10.4 CONLUSIONS

Firth (1978) concludes, after investigating the data, comprises of 150 mergers of all quoted companies in

Britain, that there is no evidence of existence of synergism created by combining firms over a period

1972-74. There is not any clue of differences being observed from the process, which create returns for
