Abstract: This study, based on Indian banking mergers, examines theimpact of mergers on both the stock market wealth creation and operating
performance. The study also analyses the performance of the merged banks in relation to a control group based on financial ratios. The results ofcumulative abnormal returns analysis signify that merger announcements arevalue-creating activities for the acquirer banks. At the same time, mergerannouncements erode shareholder wealth for the target banks. The frameworkof pre-merger and post-merger comparison of the operating performance of theacquirer banks was based on three models whereby the cash flow was deflated
by market value of assets, book value of assets, and income. The result does notprovide evidence to support the view that corporate performance improves aftermergers.
Keywords: mergers; cumulative abnormal return; CAR; acquirer; target; cashflow model.

1 Introduction
Consolidation in the banking industry worldwide can be attributed to the process of
deregulation and technological changes that facilitated many banks to provide a wider
range of banking services across a larger geographical area. Basically consolidation in the
8/3/2019 Afro Asian Journal of Finance and Accounting

banking industry is aimed at accruing gains through expense reduction, increased market
power, reduced earnings volatility, scale and scope economies.
Bank mergers can increase value by reducing costs and/or increasing revenues. Costreductions can be achieved by eliminating redundant managerial positions, closing
overlapping bank branches and consolidating back office functions. Cost cutting potential
may be greater when merging banks have geographical overlap. Revenue enhancement
can also be attributed from sources like cross selling of bank services. The main reason
for First Unions acquisition of First Fidelity Bancorp was to market its brokerage and
mutual fund services to First Fidelitys customers. The ability to raise fees and lower
interest rates on deposit accounts to raise net interest revenue can also be cited as a
motivation for acquisitions (Houston et al., 2001).
Two main research approaches explain mergers and acquisition profitability. The
event studies examine the abnormal returns to the shareholders in the period surrounding
the announcement of a merger or acquisition. The accounting studies examine the
reported financial results of acquirers before and after the acquisitions to see how the
financial performance changes. The key question in the context of corporate restructuring
issues is that whether mergers and acquisitions are value creating activities. This research
paper examines both the stock market performance as well as the operating performance.
It can be interpreted that a given merger is successful if other things equal; it increases
the total current wealth of the owners of the acquiring bank. The efficient market
hypothesis assumes that investors anticipation of future benefits will be reflected in the
merging banks stock prices at the time of acquisition announcement.
Studies on mergers and acquisitions are few in the Indian context. This study aims to
fill the gap in merger studies in banking sector by analysing both the stock market
performance and operating performance of banks involved in mergers.
2 Review of literature
Most academic studies follow one of the two distinct approaches to evaluate mergerrelated gains. The first approach compares the performance of banking institutions based
on accounting data, before and after a merger to determine whether consolidation results
in gains. By comparing pre-merger and post-merger data, performance changes
attributable to a deal can be directly estimated. The second approach examines the stock
price performance of the bidder and target bank around the announcement of a merger.
These stock market studies are based solely on market expectation and do not address the
issue of actual gains resulting from consolidation.
Cornett and Tehranian (1992) and Spindt and Tarhan (1993) find increases in post-
merger operating performance while studies by Piloff (1996), Berger and Humphrey
(1992) and Berger (1997) do not find any evidence of post-merger improvement in
performance.
The stock market studies include studies by Houston and Ryangaert (1994) and
DeLong (1998).
Cornett and Tehranian (1992) compare the pre-merger and post-merger performance
of 30 large holding company mergers occurring between 1982 and 1987. They find that
cash flow returns relative to a national group of publicly traded banks that did not merge
over the period improve following the mergers. The study further finds that merger
announcements are associated with significantly positive consolidated abnormal returns.

Cornett also finds a high correlation between positive market reaction and improvement
in post-merger return on assets (ROA). Linder and Crane (1992) find that interstate
mergers do not result in improved operating income relative to comparably located banks. Spindt and Tarhan (1993) find that mergers lead to operating gains but their
results may be primarily due to economics of scale. Studies of Piloff (1994), Berger et al.
(1999) finds little or no improvement in the post acquisition operating performance of
merged banks relative to industrial peers.
Houston and Ryngaert (1994) find little evidence of wealth creation for the acquired
bank at the expense of the shareholders of the acquirer banks. Houston and Ryngaert
(1997) find that the returns to bidders are significantly greater in bank mergers financed
with cash than mergers financed with stock.
Studies by Hannan and Wolken (1989) and Piloff (1996) examines both the average
and cross sectional properties of merger related performance changes and abnormal
returns of forty eight mergers involving publicly traded banking institutions occurring
from 1982 to 1991. The result suggests that performance gains are related primarily to
high total target and acquirer expenses and abnormal returns are associated with thedifference between the two total cost measures. The correlations of abnormal returns with
performance measures are consistently insignificant, providing direct evidence that
market expectations are unrelated to subsequent merger related gains.
DeLong (1998) finds that focusing mergers (those that increase either geographic or
product focus) increase value, whereas diversifying mergers destroy value.
Houston et al. (2001) based on the analysis of a sample of the largest bank mergers
between 1985 and 1996 finds that merger appear to result in positive revaluations of the
combined value of the bidder and target stocks. The bulk of revaluations is estimated to
cost savings rather than projected revenue enhancements.
The paper by Amihud (2002) examines the effect of cross border bank mergers on
the risk and abnormal returns of the acquiring banks. Their results suggest that on
average neither their total risk nor their systematic risk falls relative to banks in
their home banking market. The abnormal returns to acquirers are negative and
significant, but somewhat higher when risk increases relative to banks in the acquirers
home country.
DeLong (2003), based on a sample of 54 bank mergers announced between 1991 and
1995, tests several facets of focus and diversification. The study finds that upon
announcement, the market rewards the merger of partners that focus their geography and
activities and earning stream. Only one of these facets, focusing earning streams
enhances long-term performance.
Beitel et al. (2004) study 98 large M&As of European bidding banks from 1985 to
2000 in order to investigate drivers of excess returns to the shareholders of the targets, the
bidders and to the combined entity of the bidder and target. The findings show that many
of the drivers identified mostly from prior, US focused research have significant
explanatory power, indicating that the stock market reaction to M&A announcements of
European bidding banks can be at least partly forecast. The results confirm the preference
of stock markets for focused transactions and against diversification.Three papers by Tourani and Van Beek (1999), Cybo Ottone and Murgia (2000) and
Beitel et al. (2001) apply event study methodology in order to analyse announcement
effects of European bank mergers and acquisitions. The studies by Beitel et al. (2001) and
Cybo-Ottone and Murgia (2000) find that both target and bidder shareholders earn

significantly positive cumulative abnormal returns (CARs) in the event window

The study identifies successful mergers as
those that fulfil simultaneously twocriteria. First merged banks must exhibitefficiency levels above the average ofnon-merging banks. Second banks mustexhibit efficiency changes between mergerand evaluation. The study further findsthat every second merger is a success interms of either cost efficiency or profitefficiency.
2.1 Other studies related to M&A in banking
Zollo and Leshchinkskii (2000) analyse 579 US bank mergers and acquisition from 1977
to 1998 and find that the size of acquirer has significantly negative impact on the
acquirers M&A success. Seidel and Kritische (1995) analyse 123 US bidding banks
between 1989 and 1991 and show that banks which obtain an optimal size after the
transaction (in terms of assets) are more successful. They conclude that banks are most
successful, if they attain assets between US$ 2 billion and US$ 30 billion after a
transaction. Banerjee and Cooperman (2000) look at the profitability differences between
target and bidder for 30 bidding banks and 62 target banks in the USA between 1990 and
1995 and find that bidding banks are more successful when they are more profitable than
their targets. Hawawini and Swary (1990) find that bidders that are relatively more
profitable than their targets do significantly create more value in bank M&As.
Berger and Humphrey (1992) determine that mergers of large banking organisations
lead to no significant gains in X efficiency, ROA or total costs to assets. Further it reports
the amount of market overlap and the difference between acquirer and target X
efficiency. Srinivasan (1992) and Srinivasan and Wall (1992) report that mergers do
not reduce the non-interest expenses. Rhoades (1993) analyses mergers of large
institutions and conclude that cost reductions and efficiency gains are not significantly
related to mergers. Ryan (1999) opines that most bank acquisitions are not in the
interest of shareholders. Gorton and Rosen (1995) suggest that the primary motive

for bank mergers is empire building by managers who are insulated from the market
for corporate control.

Sergio and Olalla(2008)
The study examines whetherfinancial deregulation andtechnological progress has playedan important role in the process ofmergers and acquisitions (M&As)in the banking sector during the
period 19952001. Multinomiallogit analysis was used to analysethe characteristics of continentalEuropean financial institutions.
Size is an important factor in mergersand acquisitions.
Sharkas et al.(2008)
This study investigates the costand profit efficiency effects of
bank mergers on the US bankingindustry. Non-parametrictechnique of data envelopmentanalysis was used to evaluate the
production structure of mergedand non-merged banks.
The empirical results indicate thatmergers have improved the cost and
profit efficiencies of banks. Furtherevidence shows that merged bankshave lower costs than non-merged
bank because they are using the mostefficient technology available(technical efficiency) as well as a costminimising input mix (allocativeefficiency). The results also suggestthat there is an economical rationalfor future mergers in the bankingindustry.
Hagendroff et al.(2007)
This article aims to advocate anextension of empirical work tofocus more clearly on therelationship between banksgovernance attributes and thesuccess of bank mergers.
The results suggest that soundgovernance mechanisms such asmanagerial pay incentives and boardcomposition may help prevent bankexecutives from pursuing valuedestroying acquisitions.
Rezitis (2008) The study investigates the effectof acquisition activity on theefficiency and total factor
productivity of Greek banks usinga stochastic output distancefunction.
The results of the study indicate thatthe effects of mergers andacquisitions on technical efficiencyand total factor productivity growthof Greek banks are rather negative. In
particular, the technical efficiency ofmerger banks decreased in the periodafter merging, while that of non-merger banks increased over the same
period.
2.2 The world scene
The commercial banking industry accounted for more volumes of M&As than any other
industry worldwide during the period 1998. More than a fourth of total merger and
acquisition deals were involving banks totalling $102 billion (The Economist, 1999).
8/3/2019 Afro Asian Journal of Finance and Accounting

An analytical study on value creation in Indian bank mergers 113
The trend started in the USA in the 1980s. The US banking industry saw more than
7000 mergers between 1980 and 1998.The nineties saw some of the largest mergers in
banking history in the US. The number of banks in the US declined by more than a third
over 1980 to 1997. Moreover between 1994 and 2002, more than 1300 new banks were
opened in US in direct response to perceived decline in service resulting from a bank
merger. Simultaneously, the proportion of banking assets accounted for by the 100 largest
banking organisations went from over 50% in 1980 to nearly 75% in 1997. The reasons
for the mergers were a new statutory environment that allowed interstate ownership and
branching; banks seeking scale economies; geographical diversification; and, increased
competitive pressures (Meyer, 1998).3
M&A within the European financial sector has changed the European banking
landscape in the past decade. The number of European banks decreased from 12,670 in
1985 to 8295 in 1999 (European Central Bank Report, 2000). This development is mostly
driven by M&As among European banks. The European (EU-15) market concentration
measured by the market share of the top five banks in terms of total assets grew by 12%
over the last ten years to 57.1% in 1999. The number of banks per 1000 inhabitants in
Europe is almost twice as large (0.49) as in the US (0.27) indicating many more
concentration potential through M&A transaction in the near term future (European
Central Bank Report, 2000; Berger et al., 1999).
3 The Indian scene
In 1969, there were 73 scheduled commercial banks (SCBs). There are about 90 SCBs,
four non-SCBs and 196 regional rural banks (RRBs). The State Bank and its seven
associates have about 14,000 branches; 19 nationalised banks have 34,000 branches; the
RRBs 14,700 branches; and foreign banks around 225 branches. However, only State
Bank of India is among the top 200 banks in the world. Consolidation of the industry will better help banks raise capital for growth from the financial market without further
liquidating the public sector character in ownership and management.
Over the past few decades, 36 banks and non-banking finance companies have
been merged. Most of these mergers were bail out operations forced by RBI to protect
depositors money. For example, New Bank of India with Punjab National Bank in
19891990, Bank of Karad with Bank of India in 19931994 or Global Trust Bank
with Oriental Bank of Commerce in 1994, Nedungadi Bank with Punjab National
Bank or United Western Bank takeover by IDBI. The notable exceptions were
HDFC banks takeover of Times Bank, the unification of IDBI Bank with IDBI,
the merger of SCICI, Anagram Finance, ITC Classic, Bank of Madura, ICICI with
ICICI Bank. Within a span of 18 months, ICICI announced three mergers that
with SCICI, ITC Classic and Anagram Finance. On acquiring ITC Classic, ICICI own
network improved by ten branches, 12 franchises and a depositor base of almostseven lakh. Through the merger with Anagram, ICICI gained 50 branches and depositor
base of 2,50,000 in Western India. ICICI was attracted by the retail portfolio of
Anagram, which was active in lease and hire purchase, car finance, truck finance and
consumer finance. With the merger of Bank of Madura, ICICI Bank became richer by
8/3/2019 Afro Asian Journal of Finance and Accounting
8/28
114 B.R. Kumar and K.M. Suhas
almost 260 branches, 2,500 personnel, deposit base of around 37 billion and a
strong presence in the Southern States. The reverse merger of ICICI with its offspring
ICICI bank was aimed at becoming a Universal Bank which catapulted it into thesecond largest bank in India. The merger saw ICICI bank gaining critical mass and
major thrust on retail front. The merger between Standard Chartered and Grindlay
created Indias largest foreign bank. The Times Bank merger helped HDFC Bank to
increase the customer base by 2,00,000 and branches from 68 to 107 and saved the
costs associated with technology up-gradation. ING integrated its banking operation in
India with Vysya Bank and formed a common umbrella brand ING-Vysya for its
banking, asset management and insurance business of the group in India. ABN Amro
Bank NV acquired the retail banking operations of Bank of America and enhanced its
presence.
The general pattern for public sector banks has been to cater to sectors ranging from
agriculture to international banking. Private sector banks work more in terms of niches in
the area of business type. Most public sector banks except few top banks like State Bank
of India and ICICI Bank have a low presence in newer areas like derivatives, consumerbanking, and foreign institutional investor business. Fund transfer pricing plays a crucial
role in banking policy, particularly if they are to be cost effective and able to absorb
smaller banks.
The first Narasimham Committee report recommended mergers and acquisitions
to create a four tier banking structure (34 large banks with a global presence, 810
national banks and finally local and rural banks. Presently the acquiring entity need only
seek the RBIs acknowledgement. Any merger between two public sector banking
entities can take place under the norms laid down by the Banking Companies Acquisition
and Transfer of Undertakings Act 1970 and 1980 or the Bank Nationalisation Act.
According to this Act two banks can initiate merger talks but the scheme of the merger
must be finalised by the government in consultation with the Reserve Bank of India and
finally it must be placed in parliament, which has the right to modify or reject the
scheme. In case of a merger between a public sector bank and a private bank, both the
Nationalisation Act and the Company Law come into play. Finally Parliamentary
approval is necessary. The merger of two public sector banks was brought about in
19891990 when New Bank of India was merged with Punjab National Bank. However,
in 2004, the merger scheme for Bank of India and Union Bank of India did not even
reach the floor of parliament.
The international banks keen to grow inorganically through local takeovers have been
lobbying for a change in the norms governing local acquisitions. The 10% voting rights
restriction would be a major impediment to grow inorganically. Foreign banks have
focused more on corporate banking and foreign exchange business and ignored retail
finance.
The next phase of banking revolution will involve a wave of global
consolidation, mergers and acquisitions. The competitive environment has been
forcing banks across the globe to grow through mergers and acquisitions as bigger
banks can afford to provide a broad range of products apart from attaining capitaladequacy norms. Geography will play a key role in M&As in this sector. The fifth
largest bank in China is probably bigger than the top five Indian banks put together
in terms of assets. Consolidation in banking industry could lead to substantial cut in
cost per unit of production.

3.1 Objective of the study
This study examines the banking mergers in terms of wealth creation by studying boththe stock price and operating performance. M&As related gains are measured using both
the accounting based and stock price performance approach. The study examines the
effect of mergers on the wealth of shareholders of both acquire and target banks involved
in banking mergers. The study also examines whether the operating performance of the
merged entity have improved after the merger.
The stock market reaction to the merger announcement is examined in the paper. In
an efficient capital market, if there is certainty about the scope, timing and success of a
banks merger program, then the entire net present value of a merger program should be
capitalised when the program is first announced. If there is certainty about the program,
the market reaction should be ongoing as new information is released (Paul, 1983).
3.2 Hypothesis
The hypotheses tested in this paper are:
1 The study tests the hypothesis whether banking mergers are positive net present
value activity for the bidding and target banks. The merger announcement is
expected to exhibit positive abnormal returns for the acquirer and target bank.
2 The study also examines the hypothesis whether corporate performance improves
after mergers.
3.3 Methodology
Firstly the performance of the merged banks in relation to a control group was analysed
on the basis of financial ratios. Eleven merged banks performance was compared to a
control group based on the size of the banks. Banks with assets closest to those of the
combined assets of the acquirer and target banks in the year before merger was selected
as the matching banks. Economic theory states that performance is related to banks size
because of factors such as increasing returns to scale. On account of matching criteria,
exact matching bank in the sector for some mergers could not be found. Hence the
matching bank had to be taken from the industry.
The list of acquirer, target and respective control banks are given in Appendix. The
pre-merger performance of the merger banks (acquirer and target banks) were compared
with the pre-merger performance of the control banks. The pre-merger performance ratios
were the average value for three years (3, 2, 1) before the merger. Similarly the post-
merger performance ratio of the combined bank was compared with the control group
based on three-year average (+1, +2, +3 years) after merger. For the pre-merger years, the
financial ratios were calculated on the basis of the combined value of the acquirer and
target bank. For example to calculate the ROA, the combined net profit was divided by
the combined assets of both the acquirer and target in the respective years. For the post-
merger years, the merged bank value was compared with the control bank value.
Secondly the stock market performance of the acquirer and target banks during the
period surrounding the announcement of the merger was examined.

An analytical study on value creation in Indian bank mergers 117
The sample banks involved in mergers were selected based on availability of
media announcement of M&A. The media announcement of mergers was obtained from
the CMIE prowess database, financial newspapers and other websites. Those banks
involved in M&A were only considered which were traded for at least four days in a
week. The analyses were based on 16 merger events for acquirer banks and six target
banks.1
Choosing the appropriate event date is important in event studies and based generally
on the motivation of the research. The event date considered in this study is the media
announcement of M&A. A stronger test of market efficiency would use the first public
announcement date.
Methodology for stock market event study: market model methodology was used to
estimate the abnormal stock returns. Residual analysis basically tests whether the returns
to the common stock of individual bank or groups of banks is greater or less than that
predicted by general market relationships between return and risk. One problem involved
is the choice of reference period for obtaining the parameters to be used in calculating
excess returns caused by the events such as mergers. If the reference period chosen is too
long or far removed from the event, then the risk characteristics of the sample bank may
have changed in the interval. If the reference period is too short, it may not represent a
valid benchmark.
The choice of the benchmark is probably the most important factor in making
accurate measurement of a mergers impact.
The expected rate of return on the security is found out using the market model.
The model parameters were estimated by regressing daily stock return on the
market index over the estimation period. To use the market model a clean period was
chosen 100 to 250 days (0 day being the merger announcement day) to estimate
the model parameters ( and ) The market model is given by Rt = + Rmt + t
where Rmt is the return on Sensex for day t, measures the sensitivity of the bank to
market this is a measure of risk and t is a statistical error term where t = 0. Thus the
predicted return for the bank in the event period is the return given by the market model
on that day using these estimates. Market model method is the most widely used method
since it takes explicit account of both the risk associated with the market and mean
returns.
The markets reaction to a merger bid is measured using daily stock return data to
compute excess stockholder returns. These excess returns are a measure of the
stockholders return from the new information, which becomes available to market. The
daily excess return for the security is estimated by
( )t t tXR R E R =

E (Rt) predicted or expected rate of return on the security for day t.
Firstly the average excess returns (AAR) for each relative day t are calculated across thesecurities. Daily average cumulative excess returns (CAR) are sums of the average excess
returns over event time. In other words CAR is defined as the sum of previous daily
average residuals for each trading day. The t statistics are then calculated.
In the event time, the day on which a merger announcement appears in the press is
designated as 0. Trading days prior to the merger announcement are numbered event days
1, 2 and so on. The event days following the merger are numbered +1, +2 and so on.
The maximum time window involved in the study is 60 days to +60 days for the
acquirer banks and 10 to +10 for target banks. The other shorter time windows were also
applied for the acquirer and target banks. For merger announcements which occur before
the stock market closes, the proper event date is t = 1. For events which are announced
after the market closes the proper event day is t = 0.
Thirdly the operating performance of the acquirer banks before and after the merger
was examined to see how the financial performance changes. To analyse the operatingperformance, bank mergers in which the acquiring banks financial data were available
for a period of three years before and after the year of merger was selected for the study.
Banks were matched on pre-acquisition size of the merging banks. For every merger, a
matched control bank was selected based on asset size one-year prior to merger (1). In
other words banks with asset size closest to those of the combined acquirer and target
bank in the year 1 was selected as the matching control bank.
The pre- and post-acquisition operating performance of merging banks relative to
matched banks are compared based on three models. In the first model, cash flow was
deflated by market value of assets. In the second and third model, cash flow was deflated
by book value of assets and sales. The financial data for the year in which merger
occurred is omitted in order to control for accounting differences and any one time
merger cost incurred during the merger which would otherwise make it difficult to
compare them with results for other years. The performance data of target and biddingbank are aggregated before the merger to obtain the pro forma pre-merger performance of
the combined banks. Comparing the post-merger performance with the pre-merger
benchmark provides a measure of the change in performance.
The results of the three dimensions of the study are given in the Sections A, B and C.
Section A
This section gives the results of univariate analyses with respect to the performance of the
merged banks in relation to a control group based on financial ratios.
The ratio of capital to assets which is higher for the sample banks compared to
control banks was found to be statistically significant at 5% level of significance. All
other variables were statistically insignificant.
Compared to the pre-merger period the ROA decreased for the sample banks in the post-merger period. The ratios of loan to equity and deposit to equity increased from
37.91 and 66.59 for the sample banks in the pre-merger period to 59.04 and 92.23 in the
post-merger period. The ratio of fund-based income to cash flow (pbdit) for the sample
banks decreased from 1.27 to 0.877 in the post-merger period. The asset growth of the

Section B
This section discusses the results of the analyses the stock market performance of
the acquirer and target banks during the period surrounding the announcement of the
merger.
Analysis results
The CAR for the acquirer banks show irregular trend during the pre-merger
announcement time period. CAR shows steep positive upward trend during the period
surrounding the announcement day, then again shows irregular pattern. Some steep
upward trend is observed surrounding +25 days after the merger announcement. Over all
the CAR analysis during the time period 60 to +60 reveals that the negative abnormaltrend in the pre-merger period is accompanied by positive upward movement of abnormal
returns in the post-merger announcement period.
The CAR analysis of the target banks shows steep downward movement of abnormal
returns in the post-merger period. There has been negative CAR throughout the
8/3/2019 Afro Asian Journal of Finance and Accounting
15/28
An analytical study on value creation in Indian bank mergers 121
time window of 10 to +10 days. The CAR graph shows some upward movement
during the announcement day and then the gain slips down drastically down. This
observation is contrary to the general belief of the wealth gain by target banks involved inmergers.
The average alpha and beta values for the acquirer banks were 0.0013 and 0.96
respectively.

Notes: AAR average abnormal return
CAR cumulative abnormal returnIt is observed that from 12 days till +20 days after announcement of mergers, the
average abnormal return (AAR) has been positive for the acquirer banks. The study
documents an AAR of 0.062% and 0.067% on 1 and 0 day of announcement for the
acquirer banks. The maximum AAR for the acquirer banks during the period 20 to +20
was observed for +1 day after merger announcement (0.067%). But the abnormal return
analysis for the target banks for the period 10 to +10 reveal that except for the 10 and
9 day, the AARs were negative during the rest of the time window period. The AAR
was 5.57% on the day before announcement and 6.98% on the day of announcement
for the target banks. On the +10 day after announcement, the AAR was 28.62% for the
target bank. Hence it can be stated that stock market reacts negatively to merger
announcement with respect to target banks. The results may indicate that the terms of the
merger are unduly favourable to the acquirer at the expense of the target. Investors may
not perceive positive futuristic benefits from mergers for the target banks. This is evident
from the massive wealth erosion due to stock market performance of target banks.

The CAR analysis reveals that merger announcement is a value-creating activity for
acquirer banks. The CAR for the acquirer bank was 0.053% with a t statistic value of
9.39 at 1% level of significance for the 121-day surrounding the merger announcement(60 to +60). Similarly the CAR value during the time window 20 through +20 was
1.36% with statistical significance at all levels. The positive CAR value for the acquirer
banks in the time windows 10 to +10, 5 to +5 were also statistically significant.
The CAR for the target banks show steep decline during the merger announcement
period.
During the time window 10 to +10 days, the CAR declined by 253%. In other
period of analysis also the CAR showed negative returns for the target banks.
The study reports negative announcement returns for the target banks. The pattern of
market based returns for the acquirer bank was positive in all the time window period. It
can be stated that merger announcement are value-creating activities for the acquirer
banks. At the same time merger announcement erode shareholder wealth for the target
banks.
Section C
This section deals with the accounting based financial results to examine whether the
long term operating performance improves after merger.

and median net profit of the acquirer banks have increased by 144% and 187.5% in the
post-merger period of +3 year after merger compared to the pre-merger period of 3 year
before merger. The mean of the total assets have increased by 79% during the timewindow 1 to +3 year of merger. The mean of cash flow, operating profits and sales have
increased by 52%, 41.7% and 24.13% respectively during the same window period of 1
to +3 year after merger. The median of total sales increased by 166% during the time
window 3 to +3 year of merger. The median of operating profits increased by 1.57 times
during the time window 1 to +3 year. The median of total cash flow increased by 1.8
times during the time period 1 to +3 year. The median assets and net profit increased by
97% and 100% respectively during the above period.
The mean size of the target banks were about 54% of that of acquirer banks. The
median size of target banks were found to be about 16% of the size of acquirer banks.
Model 1 Cash flow to market value of assets
This model analyses the cash flow return on market value of assets relative to matched
banks. Operating cash flow ROA is profit before depreciation, interest and taxes as a
percentage of market value of assets at the beginning of each year. The market value of
assets is the sum of the market value of outstanding equity and book value of debt. Pre-
merger returns for the combined sample banks are weighted averages of target and
acquirer returns with the weights being the relative asset values of the two banks. Post-
merger returns uses data for the merged banks. Banks are matched on the basis of
combined assets of the acquiring and target banks one year prior to acquisition. Each
merger is denoted by i. The matched bank adjusted excess cash flow return is computed
for each bank and year as the difference between the sample bank value in that year and
control bank. MACRposti and MACRprei are matched bank adjusted excess cash flow
return in the post- and pre-merger periods for the bank i.
A cross-sectional regression approach is used to compare performance before and
after merger. The measure of abnormal matched bank adjusted cash flow return measure
incorporates the relation between pre- and post-merger-matched bank adjusted returns.
The excess control bank adjusted cash flow returns are estimated using the following
cross sectional regression.
i iMACRpost MACRpre + = +
where MACRposti is the mean annual matched bank adjusted cash flow return for
company i from the post-merger years and MACRprei is the pre-merger mean for the
same company. The slope coefficient captures any correlation in cash flow returns
between the pre-merger and post-merger years so that MACRprei measures the effect of
the pre-merger performance on post-merger returns. The intercept is therefore
independent of pre-merger returns.
The number of observations has been truncated due to non-availability of data. The
matched banks showed superior cash flow returns on market value of assets compared to
the sample of merging banks. The cash flow return on market value of assets is showing a
decreasing trend during the period 3 to +3 year for both the merging and control banks.
It has been observed that the market value of equity and book value of debt have
increased substantially in the post-merger period.

The difference between the mean of merging and matching bank cash flow returns arestatistically insignificant during the pre-merger period of 3, 2 years. The mean
differences were also statistically insignificant during the period +2 and +3 years. But the
mean returns are negative and statistically significant in the year 1 at 10% level of
significance (t value = 2.282). The difference between mean returns in the year +1 was
negative and statistically significant at 10% level (t = 2.123). The regression analysis
examines the impact of pre-merger matched bank cash flow returns on post-merger
matched bank cash flow returns. The intercept with a value of 0.043 is statistically
insignificant. The slope coefficient with a value of 0.128 is also statistically insignificant.
There is no evidence to suggest that post-merger performance improves based on the
market value of assets model.
Model 2 Cash flow to assets model
Operating cash flow ROA is profit before depreciation, interest and taxes divided by thebook value of assets at the beginning of the year. Pre-merger returns for the combined
bank are weighted averages of target and acquirer returns, with the weights being the
relative asset values of the two banks. Post-merger returns use data for the merged banks.
Banks are matched on the basis of acquiring and target banks combined size (measured

An analytical study on value creation in Indian bank mergers 127
by total assets) one year prior to the acquisition. The pre- and post-merger cash flow
returns on book value of assets are calculated for the control banks. Each merger is
denoted by i. The matched bank adjusted excess cash flow return is computed for eachbank and year as the difference between the sample bank value in that year and control
banks. MACRposti and MACRprei are the matched bank adjusted excess cash flow return
in the post- and pre-merger periods for the bank i. This model is not sensitive to market
revaluations of equity after merger.

Col 2 and Col 3 in panel A indicate the mean cash flow returns of the merger and
matched banks in the pre- and post-merger period. Column 4 shows the mean matched
bank adjusted cash low returns for the merger in the pre- and post-merger period. The
merger banks have greater cash flow returns in the pre-merger period compared to the
control banks. But in the entire post-merger time window, the matched control bank has
higher cash flow returns compared to the merged banks. The mean cash flow return for
the merged bank decline from 10.28% in the period 3 year to 5.51% in +3 year of
merger. In the year +1, the cash flow ROA was 1.95%.The difference of mean of
matched bank adjusted cash flow return was positive and statistically significant at 3
year. The cash flow returns for the merger banks get drastically reduced in the post-
merger years. The increase in asset size after merger with no proportionate increase in the
cash flow could be attributed to the reduction in cash flow returns. The average cash flow

128 B.R. Kumar and K.M. Suhas
returns in the pre-merger period (3 to 1) was 10.01% for merger banks and 8.08% for
the control group. The corresponding values in the post-merger period was 4.16% and
6.93% respectively. The results in the panel A and panel B (regression results) suggestthat corporate performance of banks does not improve after mergers.
Model 3 Cash flow to income model
Operating cash flow return on income is profit before depreciation, interest and taxes
divided by the total income at the beginning of the year. Pre-merger returns for the
combined bank are weighted averages of target and acquirer returns, with the weights
being the relative asset values of the two banks. Post-merger returns use data for the
merged banks. Banks are matched on the basis of acquiring and target banks combined
size (measured by total assets) one year prior to the acquisition. The pre- and post-merger
cash flow returns on book value of assets are calculated for the control banks. Each
merger is denoted by i. The matched bank adjusted excess cash flow return is computed
for each bank and year as the difference between the sample bank value in that year and
control banks. MACRposti and MACRprei are the matched bank adjusted excess cashflow return in the post- and pre-merger periods for the bank i.

An analytical study on value creation in Indian bank mergers 129
In this model cash flow was deflated by total income. The cash flow returns of merging
banks have decreased from 78.52% in the year 3 to 58.67% in the year +3. But the cash
flow returns of the control banks are showing not much difference during the period 3 to+3. The differences of matched banks adjusted returns were negative and statistically
significant at 5% level of significance during the period +1 to +3. The t value was 2.046.
The cash flow returns for matched banks were higher than the sample banks during the
period +1 to +3. The mean differences of the matched bank adjusted cash flow returns.
Over all results based on pre- and post-merger comparison and regression analysis
suggest no evidence of improvement of corporate performance.
4 Summary
The main research approaches that help us in forming a view of M&A value creation is
based on event studies and accounting studies. Event studies examine the abnormal
returns to shareholders in the period surrounding the merger announcement. Theaccounting studies examine the operating performance (based on reported financialstatements) of acquirers before and after mergers to see how financial performancechanges. This study based on Indian banking mergers examine the impact of mergers onboth the stock market wealth creation and operating performance.
The study also analysed the performance of the merged banks in relation to a controlgroup based on financial ratios. Compared to the pre-merger period the ROA decreasedfor the sample banks in the post-merger period. The ratios of loan to equity and deposit toequity increased from 37.91 and 66.59 for the sample banks in the pre-merger period to59.04 and 92.23 in the post-merger period. The ratio of fund-based income to cash flow
(profit before depreciation, interest and taxes) for the sample banks decreased from 1.27to 0.877 in the post-merger period. The asset growth of the control banks were greaterthan that of the sample banks and was statistically significant at 1%.
The results of CARs analysis signify that merger announcements are value-creating
activities for the acquirer banks. At the same time merger announcement erodeshareholder wealth for the target banks. The CAR for the acquirer bank was 0.053% witha t statistic value of 9.39 at 1% level of significance for the 121-day surrounding themerger announcement (60 to +60). The CAR value for the acquirer was positive andstatistically significant in all the time window period except during the 40 to +40 period.The CAR analysis of the target banks show steep downward movement of abnormalreturns in the post-merger period. There has been negative CAR throughout the time
window of 10 to +10 days.The framework of pre-merger and post-merger comparison of the operating
performance of the acquirer banks was based on three alternate models whereby the cashflow was deflated by market value of assets, book value of assets and income. The resultdoes not provide evidence to suggest the fact that corporate performance improves after
mergers.
5 Conclusion and implication
Deregulation and changing technology have dramatically transformed the banking
industry over the past decades enabling many banks to provide a wider range of banking

services and to service more customers across a larger geographical area. The fervour of
consolidation is based on a belief that gains can accrue through expense reduction,
increased market power, reduced earnings volatility and scale and scope economies. Ifconsolidation does in fact lead to performance gains, then the shareholder wealth can be
increased.
In Indian context, earlier most of the mergers were bail out operations forced by RBI
to protect depositors money. Winds of change appeared with the onset of financial sector
reforms. Entry barriers were removed paving the way for new entrants. Prudential and
capital adequacy norms were introduced in line with global practices. interest rates were
deregulated giving banks more freedom as well as more competition. The artificial divide
between the development financial institutions and banks have been removed.
Technology came in to impact the banks in a big way.
A merger is assumed to create value if the stock market returns of the bidder and
target increases on the announcement of the merger. The results of this study show that
mergers in the banking sector are positive net present value activities for the bidding
banks. The positive announcement returns to biding banks could be partly attributable to
positive signalling related to the value created by merger. The study documents negative
abnormal returns for the target banks. The results with respect to the acquirer banks
confirm the point that that merger programs are consistent with the value maximising
behaviour by management of the acquirer banks. Post-merger excess return experience of
acquirer banks is consistent with the efficient markets hypothesis. The results with
respect to acquirer banks returns signals the confidence of the investors in the ability of
the acquirer bank to turnaround the inefficiently managed target banks. The study finds
that the operating performance does not improve after mergers. Perhaps the real
economic gains could be analysed over a longer period of time.

Notes
1 For the stock market study, the acquirer banks like ICICI Ltd. and IndusInd Banks
involvement in two mergers at different period were considered. ICICI ltd was also includedin the target group for media announcement when the bank got merged into ICICI Bank. Thenumber of sample firms in the target group was low due to non-availability of data.
