Takeover avoidance culture and the market for corporate control
Ivan Obaydina, Ralf Zurbrueggb and Grant Richardsonb
Abstract
We conjecture that the employment of anti-takeover provisions (ATPs) is a function of a
firm’s takeover avoidance culture. Viewed in this light, the absolute number of ATPs a firm
has is of less consequence than the relative number compared to its peers in determining
board and management attitudes towards being a takeover target. By constructing a relative
entrenchment index we find an economically significant, inverted U-shape relationship
exists between the relative number of ATPs a firm has and the probability of being a target
that can also explain the probability that a firm will encounter a hostile versus friendly bid.

“There is no possibility of any condition, at any price that PeopleSoft will be sold to
anyone. No condition.”
Craig Conway, Former CEO and Director, PeopleSoft
Introduction
In June 2003 Oracle, a resource planning software company, placed a bid to purchase
the competitor PeopleSoft. At the time it did not go down well with the CEO and Director
of PeopleSoft, Craig Conway, which led to the firm closing the proverbial drawbridge by
introducing a number of anti-takeover provisions (ATPs) that would limit Oracle’s ability
to successfully take over the company without significant additional costs. Proceeding the
initial bid, both firms began suing each other and it was not for another 18 months, during
which time the CEO of PeopleSoft was ousted by the board, before support for a revised
bid by Oracle was endorsed and the takeover completed.
Whilst not a unique takeover story, it does demonstrate the key to an important
argument we make in this paper that the employment of ATPs will be a function of the
takeover avoidance culture of the firm, which itself will be a combination of both board and
management attitude towards takeovers. Whilst some firms may prefer to use ATPs to
entrench themselves, others may find value in utilizing them to enhance shareholder value.
Unfortunately, the takeover avoidance culture of the firm is not directly observable.
However, if we consider measuring the relative number of ATPs a firm has to comparable
firms, then perhaps this can proxy for it. The underlying assumption being that if there are
a cohort of firms that are similar, but one firm clearly has more or less ATPs than the others,
it likely says something about the attitude of either or both of the board and management
towards corporate transactions.

As ATPs transfer, or limit, rights from minority shareholders and block-holders to
firm incumbents, it is possible that this can improve the negotiating capacity of management
involved in a takeover, yet at the same time they can used to facilitate entrenchment and
extract private benefits of control. This leads to questions of how successful ATPs are in
limiting prospective takeovers and whether these ATPs have a detrimental impact on firm
value. In the latter case, numerous studies have empirically examined this issue and whilst
not unanimous1, the majority of research, such as by Gompers, Ishi and Metric (2003), Chi
(2005), Harford, Mansi and Maxwell (2008), and Bebchuk Cohen and Farrell (2009) find
that firm value is negatively associated with the number of ATPs a firm has at its disposal.
This suggests investors generally have a dim view of firms adopting ATPs, which partly
will be due to the perceived interference it can have on the efficient functioning of the
market for corporate control that helps ensure management are acting in the best interests
of its shareholders.
Surprisingly, studies2 focusing on the direct impact that individual provisions, such
as classified boards and poison pills, have on takeover likelihood is ambiguous.
Furthermore, if these provisions are indeed able to enhance the negotiating capacity of target
firm management, as suggested by Straska and Waller (2010) who find ATPs increase firm
value where management bargaining power is low, one would expect that these provisions
should have some impact on takeover dynamics. Despite this, empirical research finds no
support for these provisions, collectively, having any impact on takeover frequencies (Core,
Guay and Rusticus, 2006; Sokolyk, 2011). Even the notion of ATPs enhancing management
1 Work by Kadyrzhanova and Rhodes-Kropf (2011) and Stráska and Waller (2010) find that
ATPs can, under certain conditions, contribute positively to firm value.

bargaining power is questionable given the lack of consensus on this matter in the literature
(Field and Karpoff, 2002; Kadyrzhanova and Rhodes-Kropf, 2011; Sokolyk, 2011).
The above findings are puzzling given the evidence that suggest ATPs affect firm
value, which one must assume is at least partly related to the impact ATPs have on the
market for corporate control. This motivates our study as we take a different perspective
from the extant literature that examines the impact ATPs have in affecting the firm’s
probability of being a takeover target. We argue that when it comes to takeovers, a potential
acquirer will almost certainly assess a firm’s suitability as a takeover target based on a
comparison with its peers. In which case it is not the absolute number of provisions a firm
has that will be relevant, but rather the relative number of provisions it has compared to
alternative takeover targets. Importantly, the usage of these provisions within a firm that has
a strong takeover avoidance culture will be different to a firm whose board and management
are more focused on the interests of their shareholders. We conjecture that without
consideration of this, and the fact that takeover targets must be considered relative to
alternative possible acquisitions, can lead to an erroneous conclusion that there is no
relationship between the number of ATPs a firm has and the probability of it being targeted.
Our view is that if the attitudes of the board and management are relatively more
focused on maximizing shareholder wealth, rather than extracting private benefits of
control, then they are less likely to adopt ATPs to mitigate disciplinary takeovers. We
therefore expect that these firms will employ provisions sparingly and have relatively few
provisions compared to their peers. Although this may seem to make them easier takeover
targets, they are in fact targeted less as disciplinary bidding for these firms will be lower. In
addition, whilst it may be possible for the board and management to effectively entrench
themselves if they employ a relatively large number of ATPs, in smaller numbers the
prevalence of ATPs within a firm may otherwise do nothing but signal to the market that
5
the firm is attempting to entrench itself, which consequently attracts acquirers interested in
pursuing a disciplinary takeover. This leads to our hypothesis that the relationship that exists
between the relative number of provisions a firm has is nonlinear and having an inverted U-
shape relationship with the probability of being a takeover target.
Using takeover data spanning a thirteen year period from 1997 until 2009, we focus
on two primary methods to compare the relative number of provisions a firm has against
others with the probability of being an ex-post takeover target. Both methods rely on
utilizing Bebchuk et al.’s (2009) entrenchment index (E-Index). We focus on the E-Index
due to its popularity in corporate finance research to capture the level of management
entrenchment within firms3. Also, relative to other indexes, such as Gompers, Ishi and
Metric (2003) governance index, it excludes provisions that are unlikely to have an impact
on limiting takeover action. Although the importance and impact of ATPs on firm value and
takeover likelihood will always, to a greater or lesser degree, be contingent upon the
individual firm’s conditions, the popularity of the E-Index can be partially attributed to its
simplicity in calculation that provides a general gauge of the level of entrenchment within
the firm.
The first method we use is to construct a Relative E-Index to provide a proxy for the
takeover avoidance culture of the firm. Although this culture is not directly observable, we
can construct a regression model to estimate the number of ATPs a firm is expected to have
relative to other firms based on its managerial characteristics, board characteristics and other
firm-specific factors that may influence the decision of a firm to adopt ATPs. Given that
having more ATPs is associated with a reduction in firm value, if the employment of ATPs
is a function of the culture towards being taken over then this relative measure should act
3 See Straska and Waller (2014) for a review of the literature.

as a good proxy for a firm that is either more interested in avoiding takeovers or maximizing
shareholder value. We estimate the Relative E-Index by recording the deviation between the
expected to actual number of provisions a firm has in our model. Our second method uses
a one-to-one peer matching process using propensity scores from a logistic model to
compare differences in the number of provisions a firm has with like-for-like firms.
Specifically, on an annual basis, we match firms with a high E-Index against firms with
similar characteristics but with a relatively low E-Index. The difference in the number of
provisions between each matched pair of firms becomes our second measure of the relative
number of provisions a firm has.
Using the above two approaches we then examine what explanatory power the
relative number of provisions a firm has in determining firm value and takeover likelihood.
Whilst our results are congruent with Bebchuk et al. (2009) in finding a negative relationship
with firm value, we also find a robust relationship exists between the relative number of
provisions a firm has and takeover likelihood. In alignment with our hypothesis, an inverted,
U-shape relationship materializes. The results from our logistic regression find that firms
with a Relative E-Index close the zero (in other words firms whose expected number of
ATPs are close to the actual number) have a probability of being a takeover target, at 4.3
percent, that is slightly below the average, of 4.9 percent, for our entire sample of firms.
However, firms on each tail of the distribution that have the maximum number of either six
more of less provisions than expected, reduce their takeover likelihood by approximately
70 and 86 percent, respectively.
To further support these results we then proceed to show that the Relative E-Index
is a good indicator of the type of takeover that will likely occur. We find that hostile
takeovers are less likely to occur if firms have a low Relative E-Index. This is supportive of
our hypothesis as there is less reason why a hostile takeover will occur if the firm is already
7
acting in the best interests of the shareholder. As the Relative E-Index rises, the probability
of experiencing a hostile takeover increases. Our peer matching method also reveals a
nonlinear relationship as firms that are substantially entrenched, represented by having a
very high Relative E-Index, have a lower probability of experiencing a hostile takeover. This
is indicative of a successfully entrenched board or management that leads to the only way a
takeover can proceed is if they ultimately support it.
For robustness, we show results from adopting an instrumental variable approach in
analyzing our headline results. Given that we argue deviations in the number of provisions
a firm has from the expected effectively is capturing takeover avoidance culture within the
firm, it is possible that this culture is influenced by the prospect of being targeted. This
raises a reverse causality issue of whether takeovers impact takeover avoidance culture or
that this culture has an impact on a firm becoming a takeover target? To deal with this
endogeneity concern we instrument the Relative E-Index by using a measure that captures
the political culture within the state that a firm is headquartered in and show our results still
hold. Specifically, we adopt Sharkansky’s (1969) adaption of Elazar’s (1966) political
subculture index that has been shown to be correlated with a number of protectionist and
participatory measures of community involvement and attitudes. The higher the index, the
more traditionalist and conservative the attitudes of its citizens are towards change. In
regions where citizens are keen on preserving the status quo, we posit that there will also be
a greater proclivity towards the board and senior management of a firm to entrench
themselves, leading to a positive relationship with the index. In showing that it satisfies the
relevancy condition for an IV in the results of our first stage of the IV approach, it also
meets the requirement of the exclusion condition, as we do not believe that takeover
likelihood of a firm can affect a whole region’s political subcultural attitudes.
8
We also examine three other issues. We show our results remain strong when we
sub-sample our data to match a treatment group of target firms with a control group of non-
target firms to control for a possible self-selection bias that may exist in our previous results,
as takeover targets are not randomly selected (see Kadyrzhanova and Rhodes-Kropf, 2011).
We also show what happens when we focus on the impact that one specific provision can
have on firm value and takeover likelihood when examining it against a firm’s Relative E-
Index. We find that the impact of a firm having a classified board provision only affects
firms with a high Relative E-Index by reducing both firm value and takeover likelihood.
Whilst research by Field and Karpoff (2002), Faleye (2007) and Sokolyk (2011) find that
classified boards also have a negative impact on firm value, we show that it is limited to
firms that are more likely to be pursuing takeover avoidance strategies. Finally, we also
conduct analyses on the association between the relative number of provisions a firm has
and the impact it has on bid premiums. The bargaining hypothesis stipulates that ATPs can
improve the negotiating capacity of management, leading to higher bid premiums and we
therefore test to see if we can find any evidence of this. We find only weak evidence when
using our peer matching approach that there is a positive relationship between higher bid
premiums and firms with a high, relative to a low, E-Index.
Our paper contributes to the research examining the impact that ATPs have on the
market for corporate control. In contrast with the extant literature, we focus on the relative
differences in the number of provisions a firm has to other firms. Importantly, given that
ATPs can on the one hand be used for entrenchment purposes, and on the other hand they
can also be used to enhance shareholder value, we contribute to the takeover literature by
highlighting the impact that ATPs, collectively, have on takeover likelihood is a function of
the takeover avoidance culture of the firm. This leads us to hypothesize and demonstrate
that a nonlinear relationship exists between our proxy for this takeover avoidance culture
9
and the probability of being a takeover target. Additionally, we contribute to the extant
knowledge on what leads to a firm experiencing a hostile versus friendly takeover, as we
find evidence to support that it is contingent on whether the firm is using ATPs to maximize
shareholder wealth or to entrench either the board and/or management. Finally, we also
contribute to the literature that examines the effectiveness of individual provisions (such as
classified boards) in reducing the likelihood of being a takeover target, as we show that it is
is, again, dependent on the takeover avoidance culture of the firm.
The rest of the paper is organized as follows. In Section II we provide a literature
review and formerly present our hypotheses. Section III details the data and research design.
In Section IV we present our empirical results and in Section V we provide some robustness
results. Section V concludes the paper.
II. Literature review and hypotheses development
A. A review of the anti-takeover provisions literature
Given the nature of modern corporations where ownership is separated from control
rights, agency problems may arise when the interests of the principal (i.e. directors of a
company) do not align with that of the agent (i.e. shareholders). To protect the interest of
shareholders, and help to align the interests of both parties, internal and external governance
mechanisms exist to curtail non-value maximizing behavior by incumbents (Core, Guay and
Rusticus, 2006). Importantly, as Jensen (1993) highlights, given the failings of internal
governance controls, external governance is essential if the interests of management are to
be aligned with that of shareholders. Accordingly, it may be argued that any impediments
to the external disciplining mechanism are detrimental to firm value. This raises the question
as to whether mechanisms such as ATPs are either an impediment or a benefit for the firm.
10
In addressing this question, Gompers et al. (2003) develop an equally weighted
index (hereafter GIM-Index) for the number of anti-takeover provisions a firm has at its
disposal to proxy for corporate governance quality. As these provisions are expected to
transfer rights from shareholders to incumbents, they show that the GIM index has a
negative relationship with firm value. They also find that firms with many provisions, which
they call dictatorship firms, exhibit sub-standard market performance relative to firms with
fewer provisions.
Bebchuk et al. (2009) re-examine the GIM index and refine it by identifying a subset
of provisions that should matter the most. Through empirical testing, interviews with
leading M&A legal practitioners and reviews of shareholder precatory resolutions, they
establish that not all provisions are of material importance. They identify only six provisions
that are substantive to explaining the inverse relationship between ATPs and firm value
uncovered by Gompers et al. (2003). Using these six provisions, Bebchuk et al. (2009)
construct a new governance index (E-Index). Four of the six provisions impose
‘constitutional limitations’ on shareholder voting rights. The remaining two provisions are
often regarded as ‘takeover readiness’ measures. If such provisions facilitate managerial
entrenchment, by reducing the effectiveness of the market for corporate control, firm value
would likely fall. Similar to Gompers, et al. (2003), Bebchuk et al. (2009) also find a
negative relationship between their E-Index and firm value.
There are, however, some studies that show ATPs can have a positive effect on firm
value. Stráska and Waller (2010), for example, show that firm value, measured using
Tobin’s Q, is positively related to the GIM index where management have low bargaining
power. Kadyrzhanova and Rhodes-Kropf (2011) also find Tobin’s Q is positively related to
the prevalence of certain ATPs that can delay a takeover in concentrated industries.
Therefore, although the bulk of the established literature (Gompers et al., 2003; Chi, 2005;
11
Faleye, 2007; Harford, Mansi and Maxwell, 2008 and Bebchuk et al., 2009) suggests the
relationship between firm value and the incidence of ATPs is negative, the result can be
context-dependent.
With regards to takeover likelihood, the research to-date has produced mixed results
in terms of its relationship with the number of provisions a firm has. Early work by Pound
(1987) and Field and Karpoff (2002) that examine the availablity of poison pills and
classified boards, respectively, find a negative relationship. These studies suggest that
provisions lead to managerial entrenchment. However, other research which applies the
GIM index finds contrary results that do not support the entrenchment hypothesis. Core et
al. (2006) do not find that takeover frequencies differ between high and low GIM index
firms. Consistent with this, Sokolyk (2011) also shows that there is no relationship between
the index and takeover likelihood. When examining the components of the GIM index, he
does find that a subset of the provisions have a notable impact on takeover likelihood and
transaction outcomes. For instance, poison pills and classified board provisions decrease
takeover likelihood, whereas golden parachutes and compensation plans increase it.
Along with research that suggests ATPs support managerial entrenchment, research
has shown it facilitates management to extract private benefits of control (DeAngelo and
Rice, 1983; Masulis, Wang and Xie, 2007; Bates et al., 2008; Harford, Humphery-Jenner
and Powell, 2012). Giroud and Mueller (2011) examine the impact of high GIM index firms
and find that ATPs do increase managerial slack if the firm operates in a non-competitive
(i.e. concentrated) industry. This finding suggests that ATPs may be used to facilitate
agency problems, but only if external pressures do not force management to make optimal
investment decisions.
12
Several studies have also considered whether ATPs are used to maximize the pay-
off target firm shareholders receive in the event of a takeover contest (Stulz, 1988; Field
and Karpoff, 2002; Kadyrzhanova and Rhodes-Kropf, 2011; Sokolyk, 2011). As first
articulated by Stulz (1988), takeover defenses which limit shareholder rights have the
potential to enhance takeover premiums by deterring opportunistic bidding that may
otherwise occur. Contrary to this proposition, Field and Karpoff (2002) find no evidence to
suggest that firm-level provisions, or state level takeover-laws, that empower management
are related to takeover bid premiums. Heron et al. (2006), on the other hand, find that ATPs
can help management with low ownership to negotiate for more favorable merger terms.
Similarly, Kadyrzhanova and Rhodes-Kropf (2011) also find evidence to suggest that
certain ATPs have a positive impact on offer premiums, when controlling for the economic
environment in which a firm operates.
B. Hypotheses development
Our hypothesis relates to the association that ATPs have with the market for
corporate control. Whilst we would expect that the number of ATPs a firm adopts has an
impact on firm value, when it comes to the takeover market we argue that what matters
more is not how many provisions a firm has, per se, but rather how many provisions a firm
has relative to its peers. As acquirers will likely compare similar firms when choosing a
target, we believe it is more relevant to examine the relative surplus or deficit number of
provisions a firm has.
A couple of possibilities arise as to how this relationship will look like. It could be
argued that as the number of surplus provisions a firm has increases, and assuming these
ATPs are effective in facilitating the entrenchment of either or both the board and
management, the probability of becoming a takeover target would decrease. In other words,
13
incumbents may be deploying these provisions in a manner aimed at impairing the
disciplinary function of the market for corporate control. As such, an acquirer who is in
search of a new target would likely choose a firm with less anti-takeover provisions than
one with more, if all else is the same. In cases where too few provisions have been ratified,
a firm may be unable to defend itself against opportunistic bidders seeking to exploit
temporary stock mispricing or shareholder myopic behavior; increasing takeover likelihood.
Based on this line of reasoning, the expected relationship between takeover likelihood and
the number of surplus provisions a firm has will be negative.
However, it is also possible to posit that a positive relationship exists between
takeover likelihood and the number of surplus provisions a firm has. If these provisions
provide insight into the takeover avoidance culture of the firm, then firms with a relative
excess number of provisions may act as a signal to the market that incumbents within the
firm are entrenching their positions and potentially not acting in the interests of their
shareholders, leading to the likelihood of disciplinary takeovers to increase. Therefore, a
positive relationship between a surplus number of provisions and takeover likelihood can
be posited. Likewise, a firm with very few ATPs may be indicative of management focused
on maximizing shareholder wealth and therefore will not need to concern themselves with
the prospect of disciplinary takeovers. This provides the basis for our first hypothesis:
H1: A positive, linear relationship exists between takeover likelihood and the number
of surplus provisions.
There is, however, an extension to this line of logic if one allows for a non-linear
relationship to exist between takeover likelihood and the number of surplus provisions. If
ATPs are ineffective in deterring takeovers, then their prevalent usage across the corporate
sector would be hard to explain. What may be the case is that ATPs entrench management
14
in some instances, but not others. It might be, for example, that a substantive number of
anti-takeover provisions need to be employed before any form of entrenchment strategy is
successful in reducing the likelihood of being targeted. It is therefore possible that these
ATPs are successful in reducing the likelihood of a takeover only where there are large
deviations in the number of ATPs one firm has relative to others. This is represented in
Figure 1 for firms that are on the far right of the horizontal axis. An inflexion point arises
where additional provisions begin to reduce the probability of being a takeover target. At
the other end of the spectrum (the left side of the horizontal axis in Figure 1) firms with
relatively few ATPs are more likely to be focused on shareholder-wealth maximization and
thus will be less likely to be targeted for disciplinary or opportunistic bidding.
How ATPs affect the market for corporate control, therefore, is expected to be
conditional on the firm’s attitude towards being acquired that potentially can be captured by
looking at the relative number of provisions a firm has. This leads us to our second
hypothesis that a non-linear relationship exists between the number of surplus provisions a
firm has and takeover likelihood:
H2: A nonlinear, inverted U-shape relationship exists between takeover likelihood and
the number of surplus provisions.
III. Data and Methodology
A. Data
As we collect data from a number of sources our final sample period is based on
matching the common start and end dates across several databases. Specifically, we examine
a period from 1997 to 2009. All firm-level ATPs are extracted from the Institutional
15
Shareholder Services (ISS) governance database (formerly Risk Metrics). To complement
this, we utilize Compustat data to provide firm-level information concerning the asset
structure of each firm and other control variables. The complete set of variables employed
in our study is provided in the Appendix. SDC Platinum is used to identify takeover targets,
along with other relevant takeover transaction related information such as deal value and
method of payment.
We also collect data on managerial characteristics, ownership and board structure
from Execucomp, Thomson Reuter’s 13F-filings and ISS Directors databases, respectively.
Where data on governance provisions are not available, we follow the method employed by
Gompers et al. (2003) to populate missing year observations. Specifically, we use the
previous year (that is available) to proxy for missing year governance provisions. We also
assume that data on governance provisions in 2006 are valid for a further three years.
When merging the different databases we drop dual-class firms from our sample.
Dual class firms are not considered given that management can stop unwanted takeover
attempts via their often substantial voting rights (Gompers et al., 2003; Masulis, Wang and
Xie, 2009). We also exclude utilities, financials and miscellaneous industries. Utilities and
financials are excluded because of differences in laws, in comparison to non-utilities and
non-financial stocks, governing the operation and acquisition activities of such firms
(Daines and Klausner, 2001; Kadyrzhanova and Rhodes-Kropf, 2011). Industry assignment
is based on the Fama and French (1997) 12-industry classification codes.
Our final sample consists of 11,989 firm-year observations which is made up of
1,797 individual firms of which 597 unique firms are subject to a takeover bid. We only
consider takeovers with transaction values in excess of $10 million. In addition to this, bids
that have transaction values in excess of the 99th percentile are trimmed from the sample.
16
To avoid double counting targeted firms (Kadyrzhanova and Rhodes-Kropf, 2011) we only
consider initial bids in our analysis. In line with Bates et al. (2008), follow-on bids (defined
as bids that occur within 365 days of a previous bid announcement for the target) are
dropped from our sample.
B. Determining the relative number of provisions
We use one of the most widely used measures in the literature to capture the level of
takeover defenses a firm has at its disposal to generate our relative measures. Bebchuk et
al.’s (2009) entrenchment index (E-Index) is based on the number of provisions a firm has
that they identify can substantively influence takeover contests. Specifically, there are six
provisions that can constitute the E-Index, all of them having the potential to impact
corporate control transactions, with four specifically related to takeovers.4
Our Relative E-Index is constructed by first running a cross-sectional regression to
explain variations in the E-Index across all firms in our sample. For each firm i in year t we
estimate the expected number of provisions it has based on managerial characteristics, board
characteristics and controls that may influence the decision to adopt provisions. Together,
we expect these factors to capture the takeover avoidance culture of the firm:
E-Indexi,t = f (Managerial Attributesi,t + Board Characteristicsi,t +
Firm Characteristicsi,t) (1)
4 The six provisions that constitute the E-Index are classified boards, poison pills, golden parachutes,
supermajority voting requirements for mergers, limits to shareholder bylaw changes and charter amendments.
The first four will have a direct bearing on the outcome of a takeover whilst the remaining may have depending
on what the specific provisions relate to.
17
For managerial attributes and board characteristics we use Field and Karpoff’s (2002) set of
variables which they apply to establish the determinants of IPO firms’ use of takeover
defenses. This includes CEO compensation, tenure and age. For monitoring and control we
use board independence, board size plus CEO and chair duality. Industry-adjusted book
value of equity and industry-adjusted leverage (debt to assets) are also added as control
variables as they may also influence the firm’s decision to adopt ATPs. The Appendix
details how each variable is constructed. To establish a firm’s relative number of surplus,
or deficit, provisions we subtract the number of expected provisions a firm should have from
estimating equation (1) and subtract it from the actual number of provisions a firm employs.
This provides us with a Relative E-Index score for each firm.
The advantage of the above measure is that it provides a simple score of the number
of provisions a firm has relative to the rest of the sample. The disadvantage is that we are
not directly comparing like-for-like firms. Our second approach deals with this by
identifying the differences in the number of provisions a firm has through a one-to-one peer
matching process. We achieve this by first splitting our sample of firms into two groups.
One cohort contains firms with an E-Index score above the median in the sample, and
another cohort with an E-Index value below the sample median. We then run a logistic
model similar to equation (1), except that this time the dependent variable is either equal to
one if the firm is placed in the cohort that have a large number of provisions (a high E-Index
score), and zero otherwise. From the regression we obtain a propensity score for each firm
which we use to match firms between the two cohorts. The matching is done on a one-to-
one basis without replacement and with a calipher threshold set at 1%. Firms that cannot be
matched are discarded. Importantly, our matches are done on an annual basis and only
between firms within the same industry. This leaves us with a new sub-sample of firms
where for each firm with a small number of provisions, there is another with a large number
18
that is similar in terms of the industry they are in plus managerial, board and firm
characteristics. The difference in provisions between each pair of matched firms we call
PeerMatchDiff.
C. Summary Statistics
Descriptive statistics for the mean, median and standard deviation of the primary
variables used in our empirical analysis are provided in Table I. Firms are split between
non-target and target firms, with the last two columns displaying the mean difference
between the two subsets and the p-value for the test in differences in these means. The first
set of variables are of the governance and entrenchment indexes, namely the E-Index and
GIM Index. We include the GIM Index for comparison purposes. The mean and median
values of the E-Index for our sample are 2.44 and 2, respectively. It is worth highlighting
that Masulis et al. (2007) differentiate between good and poorly governed firms by using an
E-Index value of 2 as the cut-off. If firms have an E-Index score that is greater than 2, they
are categorized as having poor governance. Using this criterion our data is approximately
evenly split between good and poorly governed firms. In addition, it is interesting to note
there is no significant difference between target and non-target firms for the E-Index,
implying it has no explanatory power, at least on an individual basis, in determining whether
a firm is going to be a takeover target or not.
Whilst there is no statistical difference between target and non-target firms insofar
as the number of the E-Index, there are in terms of their managerial attributes. Specifically,
the CEO cash compensation of targeted firms is higher (at the 1% level), plus the tenure and
age of the CEO is lower (at the 10% and 5% levels, respectively). Whilst there are no
significant differences for our measures of monitoring and control, some differences do
exist within our list of additional variables used for estimating our E-Index that also serve

as controls in our subsequent regressions. Specifically, at the 1% level, targeted firms in our
sample are smaller, have lower return on assets (ROA), and lower Tobin’s Q. These last
two features may suggest that the sample of target firms are not performing as well, relative
to the non-acquisition sample of firms. These firms also tend to be younger and have higher
institutional ownership (at the 1% level).
[INSERT TABLE I]
Pearson correlation coefficients are reported in Table II for the variables that we use
to estimate the E-Index, as well as with the GIM Index for comparison purposes. The
correlation of the E-Index with the GIM-Index (0.736) is positive, implying that firms with
a higher E-Index are also likely to have more of the other provisions that Bebchuk et al.
(2009) omit. We also include firm value (Tobin’s Q) in the correlation matrix that has a
negative correlation coefficient of -0.156 with the E-Index, which is consistent with the
majority of the literature that show ATPs lower firm value (Gompers et al., 2003; Bebchuk
et al., 2009).
[INSERT TABLE II]
In Table III we provide summary statistics on the corporate control transactions
within our sample. The number of corporate control transactions, relative to the total number
of firm-year observations, is 4.98%. However, 35.44% of all firms in our sample are
involved in a corporate control transaction at some stage during the sample period. Of the
597 initial bid transactions considered in this study, 80.54% were completed. The average
transaction value is $353.80 million, whereas the median is $136.15 million. Clearly, there
is significant skewness in the distribution of deal values in our sample. This is due to a
limited number of large-scale takeover transactions in the sample. Average bid premiums
are 21.94%, and largely in line with that of previous studies (see Kadyrzhanova and Rhodes-
20
Kropf, 2011). Given that the average market capitalization is $1.51 billion for our sample
of firms, this translates to an average bid premium value of approximately $300 million.
The average cumulative abnormal return that target firm shareholders realize over the
duration of a bid is 32.57%, which represents a substantial gain in target firm shareholder
wealth over a relatively short period of time.
In terms of how deals are structured, the predominant method of payment is cash.
All cash bids represent 45.20% of the transactions in our sample. Stock bids make up
38.67%, with the remainder of bids (16.13%) having both a cash and stock component.
Interestingly, few bidders choose to acquire a toehold in the target prior to launching the
official bid. In fact, only in 6.15% of the bids did the acquirer hold a toehold stake. Hostile
bids make up 10.76% of the sample.
[INSERT TABLE III]
In Table IV we report governance, board and firm-level characteristics associated
with low and high Relative E-Index firms. Firms are split into low and high cohorts based
on the median of the Relative E-Index. We also use a similar process for our peer matched
firms which are split by the median value of the E-Index in our sample. There are differences
when one looks at the Relative E-Index split compared to the PeerMatchDiff split in terms
of which variables are significantly different across the high and low cohorts. However,
what is common in both cases is that firm value (Tobin’s Q) is always negatively related to
having a higher number of provisions, indicative of ATPs destroying firm value.

IV. Empirical results
A. The relative number of provisions and firm value
We begin our empirical analyses by examining the relationship our two approaches
to measuring the relative number of provisions a firm has with firm value. Our a priori
expectation is that regardless of whether an absolute number of provisions are used or a
relative number, there should be a negative relationship between the more ATPs a firm has
and firm value. In Table V we set the dependent variable to be Tobin’s Q. To provide a
benchmark with what happens when we apply Bebchuk et al.’s (2009) original E-Index, in
column (1) we regress firm value against the original E-Index term and a set of firm specific
controls that may also explain firm value. Our selection of control variables is based on the
common firm-specific factors that other papers that examine ATPs with firm value use.
These controls include the sales growth of the firm, return on assets, free cash flow, leverage
– measured as the proportion of debt to equity in the firm, the natural logarithm of the firm’s
market capitalization, a block holder dummy that has the value of zero if an institutional
investor owns more than 5% of the firm, and zero otherwise, the proportion of intangible
assets to total assets, and the concentration of the industry the firm is in. We also include
industry and year fixed effects to account for any further unobservable factors that we have
not explicitly accounted for. In column (2) we also include the quadratic form of the E-
Index to check for a possible nonlinear relationship between the number of provisions a firm
has and firm value.
Consistent with the literature, we find that the coefficients for the E-Index in both
regressions are negative and statistically significant at the 1% level, with no evidence of a
22
nonlinear relationship. Based on the estimated coefficient value for the E-Index in column
(2), each unit rise in the E-Index leads to an 8.8% decline in firm value.
In columns (3) and (4) we repeat the first two regressions but replace the E-Index
with our Relative E-Index measure. The results are similar with the coefficient for Relative
E-Index being negative and significant in both regressions at the 5% level. The interpretation
is slightly different as now the variable of interest expresses the relative number of
provisions a firm when accounting for certain board and management characteristics. Based
on the estimated coefficient value for the Relative E-Index, for each additional provision a
firm has relative to what is expected leads to firm value declining by 7.03%. Columns (5)
and (6) show the results from a reduced sample of peer-matched firms. The results are very
similar to our earlier regression results, showing again that a significant negative
relationship, at the 1% level, exists between the number of provisions employed by a firm
and firm value.
[INSERT TABLE V]
Taken together, the results from Table V are in alignment with the existing literature
on ATPs and firm value. We are able to show that our two approaches capture the same
negative relationship that an absolute measure of the number of ATPs a firm has on firm
value. As a robustness check, we also use the Fama and MacBeth (1973) two-stage approach
to examine the relationship between the relative number of ATPs a firm employs and firm
value. This approach avoids clustering the standard errors by firms. In the first stage, we
run a series of cross-sectional regressions pooled by year for the firms in our sample. We
then average the coefficients from these regressions across years to obtain the Fama-
MacBeth factor loadings for our second-stage regressions. The results from this approach,
23
using Newey-West (1987) adjusted standard errors that are robust to serial correlation across
firms, are qualitatively the same as the results we report in Table V.
B. The relative number of provisions and the market for corporate control
Although our independent variables remain the same to what we used for examining
firm value, the dependent variable is now a binary which is set to one if a firm is targeted,
and zero otherwise. Table VI shows the results from probit regressions using this dependent
variable, and as with Table V, we first present the results obtained from using the standard
E-Index first to set a benchmark against our measures of the number of relative provisions
a firm employs. The results from columns (1) and (2) show that neither the coefficient for
the E-Index nor its quadratic form are significantly related to the probability of a firm being
targeted.
The above results are in contrast to what we find when we measure the relative number
of provisions a firm has against either our whole sample using the Relative E-Index
(columns 3 and 4) or when we use our peer-matched sample of firms (columns 5 and 6). In
column (1) we find that the coefficient for the Relative E-Index is positive and significant
at the 1% level with a coefficient value of 0.0208. This result is contrary to the argument
that if ATPs are effective in entrenching management as this implies the more provisions a
firm employs, the probability of being a takeover target should decline. Instead, we find
evidence that supports our first hypothesis that having less provisions leads to a reduction
in takeover likelihood. Firms with relatively fewer provisions are more likely to be less
averse to protecting themselves against takeovers as they are focused on shareholder wealth
as opposed to entrenching their own positions. As a result, they are less likely to face the
prospect of disciplinary takeovers.
24
When we turn our attention to the nonlinear case, tabulated in column (4), we find that
the estimated coefficient for the Relative E-Index remains positive and significant, as well
as the size being similar (0.0239). However, the coefficient of the squared Relative E-Index
term is also significant at the 1% level. The coefficient is negative, and the magnitude of the
coefficient is smaller (-0.0182) than the coefficient for the linear term, leading to an inverted
U-shape relationship forming between the number of excess provisions a firm employs and
takeover likelihood. We interpret this result as suggesting that where firms employ a number
of ATPs beyond a certain threshold, entrenchment begins to be successful. This
entrenchment threshold is reached just after the firm has more than one additional provision
than what is expected. In Figure 2, the probability of being a takeover target is inferred from
our baseline probit model, estimated and reported in model (4) of table six, and plotted
against the Relative E-Index score. To derive the expected probability of a firm being
targeted we set all control variables to the sample average and then extract the probability
of being targeted by changing the Relative E-Index score, in one unit increments, from -6
(the lowest possible score) to +6 (the highest possible score). A firm, for example, that is
expected to have no ATPs from the entrenchment index (E-Index), yet has all six provisions,
reduces the likelihood of being a takeover target, in a given year, by 70.01%, to a value of
1.29% percent. On the other hand, firms with fewer provisions than expected also reduce
the likelihood of being a takeover target. Those firms that are expected to have six
provisions, but instead have none, reduce their probability of being a takeover target, in a
given year, by 86.05%, to 0.60%. Right in the middle, for firms that have the same amount
of ATPs as to what is expected, have a probability of being targeted (4.3%) that is slightly
below the mean for our entire sample (4.86%).
The results from our peer matched sample provide a similar story, showing a significant
quadratic relationship exists between the number of ATPs a firm has and takeover
25
likelihood. As such, our results match our second hypothesis and suggest our approaches to
capturing the relative number of provisions a firm has, as opposed to the absolute value, can
explain the probability of a firm being targeted. We also believe these results are consistent
with the results from Table V that show firms with a relative deficit number of provisions
also have higher firm value. Firms with relatively few provisions are more likely to be run
in the interests of the shareholder and therefore reduce the possibility of disciplinary
takeovers.
[INSERT TABLE VI]
Although not tabulated, we conduct a number of other tests to check the reliability
and consistency of using our Relative E-Index when we change how it is estimated. We
consider what happens if we group each firm into its respective industry classification and
then run a series of rolling regressions (by year for each industry) to determine the
Relative E-Index. We also consider what happens when we further filter and drop some of
our explanatory variables. For example, to avoid capturing the attitude of a departed CEO
in influencing firm culture, we restrict the sample to firms with a CEO that has a minimum
tenure of two years. Our results, however, remain qualitatively the same, showing a strong
nonlinear relationship exists between the Relative E-Index and the probability of being
targeted.
C. Robustness tests
In this section we conduct a number of robustness checks and auxiliary analysis to
complement our baseline results on the relationship that the number of ATPs have with
takeover likelihood. To start, we address a possible endogeneity concern. If the relative
number of ATPs a firm adopts is related to the takeover avoidance culture of the firm, then
26
it raises the question of whether takeover likelihood can also influence the firm’s culture
towards being taken over? To deal with this reverse-causality concern, and concerns that
our Relative E-Index is proxying for unknown, omitted variables within our econometric
modeling that lead to a spurious association between our measures with takeover likelihood,
we instrument it with Sharkansky’s (1969) adaption of Elazar’s (1966) political subculture
index that has been shown to be correlated with a number of protectionist and participatory
measures of community involvement and attitudes. Sharkansky (1969) shows that the higher
the index, the more traditionalist and conservative the attitudes of its citizens are towards
change. In regions where citizens are keen on preserving the status quo, we posit that there
will also be a greater proclivity towards the board and senior management of a firm to
entrench themselves, as a desire to avoid change. This should lead to a positive relationship
with the index. Also, as one cannot argue that the takeover likelihood of a firm will affect a
whole region’s political subcultural attitudes, the IV meets the exclusion condition for being
a suitable instrument. For every firm, we associate it with a Sharkansky score based on the
state where it is headquartered.
Table VII presents the results of estimating the probability of being a takeover target
using a two-stage least squares probit approach when applying the Sharkansky index to
instrument for our measures of the relative number of provisions a firm has. In column (1)
we show the first-stage regression results, where the instrumental variable (Sharkansky
Score) has the expected, positive sign and is significant at the 1% level. When we use the
predicted values from the regression of column (1) to replace the Relative E-Index variable
in column (2), we find it is significant at the 10% level and also has the correct, hypothesized
sign.
In columns (3) and (4) we repeat the regressions when adding the quadratic term. As
we now require a second IV, we follow Wooldridge (2002) and estimate a second, first-
27
stage regression where we use the squared predicted values obtained from the first
regression in column (1) to predict the square of the Relative E-Index. Column (3) shows
the regression results where the coefficient for the square of the predicted values obtained
from column (1) is significant, at the 1% level, along with having a positive relationship
with the probability of being a takeover target. Using the predicted values from this
regression for the square of the Relative E-Index we then estimate our second-stage
quadratic model with the results tabulated in column (4). We show that for our two
instrumented variables, one being the Relative E-Index and the other for its square term,
their estimated coefficients are both significant at the 10% and have the expected signs that
lead to an inverted, U-shape relationship materializing. In columns (5) to (8) the analysis is
repeated for our peer matched sample where we use the Hostile Experience variable to
instrument for the E-Index and the results are stronger, as our instrumented Relative E-
Index, and its quadratic term, are now significant at the 1% level in column (6), and the 5%
levels in column (8).
[INSERT TABLE VII]
Another issue that arises when examining takeover likelihood determinants is that
targets are not randomly selected (Kadyrzhanova and Rhodes-Kropf, 2011). To address this
particular issue, we utilize propensity score matching (PSM) to match a treatment group of
target firms with a control group of non-target firms. We first run a logit regression to
determine the propensity scores for each firm in our sample based on the same set of control
variables used in the baseline regression of Table VI. We then match each target firm,
without replacement, with a non-target firm where the caliper does not exceed 0.01 standard
deviations. This reduces our sample size from 11,989 to 2,160. Table VIII presents the
results from re-running our baseline regressions presented in Table VI. In terms of statistical
28
significance, sign and the relative magnitudes between our ATP measures and its square
term, nothing substantially changes.
[INSERT TABLE VIII]
We next consider if capturing the relative number of provisions a firm has can also predict
the probability that a firm will experience a hostile, versus a negotiated / friendly takeover.
If it is true that, for example, our Relative E-Index is a proxy for the takeover avoidance
culture of the firm, then we should find firms with a low Relative E-Index should experience
less disciplinary (hostile) takeovers given that they are more likely using ATPs for the
benefit of the shareholder rather than for board and/or management entrenchment. In Table
X we regress the probability of receiving a hostile bid against the standard E-Index, the
Relative E-Index and our peer-matched sample of firms. We use a two-stage Heckman
probit model where in the first stage the regressor is the probability of receiving a bid, and
in the second stage it is whether the bid is hostile or not. In the second stage we also add a
number of deal characteristics that the literature has shown to influence bid attributes. These
deal characteristics include whether there is an established toehold or not, whether the bid
is an all cash payment and whether the bid is a tender offer or not.
The results show that if we use the benchmark E-Index (columns 1 and 2), no
relationship can be found between the absolute number of ATPs a firm has and the
probability that the firm experiences a hostile bid. However, when we use the Relative E-
Index (columns 3 and 4), we find evidence of a significant positive, linear relationship. If
we focus on the peer matched sample of firms (columns 5 and 6) the significance of the
results become stronger and we also find evidence of a nonlinear relationship. As the
coefficient for the squared E-Index term in column (6) is significant and negative (but with
a smaller coefficient size than the coefficient for the E-Index term), it suggests an inverted
U-shape relationship exists between the probability of experiencing a hostile bid and the
29
relative number of ATPs a firm has. We believe this is a result of the fact that if the board
and / or management have successfully entrenched themselves the only way a bid will be
successful is if it in negotiated. The case in point would be our example with PeopleSoft.
At the end of the day a negotiated settlement was reached.
[INSERT TABLE X]
In Tables XI and XII we examine the impact that one specific provision, classified boards,
can have on the likelihood of being a takeover target. This provision limits the ability for an
acquirer to clear out the acquired firm’s board as board members serve overlapping terms
and cannot be completely replaced following a takeover. Whilst on the one hand this
provision may be utilized to entrench board members and make it less appealing for
acquirers to target the company (Daines and Klausner, 2001; Bebchuk, Coates and
Subramanian, 2002; Bebchuk and Cohen, 2005; Faleye, 2007), it can also be argued that
classified boards, under certain conditions, contribute positively to firm value by promoting
board stability (Wilcox, 2002; Ahn and Shrestha 2013; Johnson, Karpoff and Yi, 2015). For
this reason, examining the impact that this provision can have on firm value and takeover
likelihood is a good case study as its impact may well be firms-specific. If it is true that
firms with a relatively small number of provisions are less likely to be employing ATPs for
entrenchment purposes, then investors should not react negatively to the employment of this
provision, as well as it not having any impact on takeover likelihood. Conversely, if firms
with a relatively large number of provisions is indicative of firms entrenching the board and
management then both firm value and takeover likelihood should decline.
To test the above we split our sample into a cohort of firms with a low Relative E-
Index (column 2 of each table) versus those with a high Relative E-Index (column 3 of
each table). For Table XI the dependent variable is our firm value measure, Tobin’s Q,
which is regressed against our usual set of control variables plus a dummy variable that is
30
equal to one if the firm has a classified board provision and zero otherwise. When we
examine the regression results from using the full sample (column 1) the estimated
coefficient for the classified board dummy is significant at the 5% level and negative,
implying firm value declines if this specific provision is present within the firm. However,
when we look at the regression results from the two subsamples, they suggest that the
impact on firm value is only present for firms with a high Relative E-Index. Whilst
research by Field and Karpoff (2002), Faleye (2007) and Sokolyk (2011) find that
classified boards also have a negative impact on firm value, our results show that it is
limited to firms that are more likely to be pursuing takeover avoidance strategies. Similar
results appear when we examine the probability of being a takeover target in Table XII, as
a significant relationship only exists for high Relative E-Index firms.
[INSERT TABLE XI and XII]
As a final extension to our analyses of takeover likelihood, Table XIII examines whether
measuring the relative number of provisions a firm has can affect bid premiums. As part of
this we also need to account for a possible self-selection bias takeover premiums may, in
part, reflect the market’s expectation of a takeover bid. We deal with this issue by employing
a two-stage Heckman (1979) approach where in the first state we use the original probit
regressions from Table VI to determine the likelihood of being targeted. To ameliorate
multicollinearity concerns, FIRM AGE is used as an instrument for takeover likelihood in
this first-stage regression. Similar to the argument presented by Kadyrzhanova and Rhodes-
Kropf (2011), we use FIRM AGE at the time of the firm’s initial public offering as it is
correlated with takeover likelihood (i.e. firm exit) but not takeover premiums. We then
compute the inverse Mills ratio and include it in the second stage OLS regression that is
reported in Table XIII. In addition to our usual set of control variables, we also add deal-
specific controls used in Table X. The results, however, are not particularly strong as we
31
only find evidence that the relative number of provisions a firm has positively affects bid
premiums for the matched sample of firms in columns (5) and (6). The estimated coefficient
for the E-Index in column (5) is significant at the 5% level. To double-check whether there
is any stronger result if we look at takeover contest returns, we redo the above analysis but
replace the dependent variable with auction cumulative returns but fail to find, again,
consistent significant results between our different approaches for capturing the relative
number of provisions a firm has.
[INSERT TABLE XIII]
V. Conclusion
In this paper we contribute to the established literature by demonstrating the
importance of considering the relative number of anti-takeover provisions a firm employs
in determining the relationship it has with takeover likelihood. We relate deviations in the
actual number of provisions a firm has against an expected number, based on board and
management characteristics plus other firm-specific factors. Our argument is that when it
comes to an acquirer determining which firm it will bid for, the impact of the number of
ATPs a firm has must be considered to other comparable firms. Moreover, the relative
deficit or surplus number of provisions a firm has can proxy for a firm’s takeover avoidance
culture. If the board and / or management of the firm are more concerned with private
benefits of control, then they are more likely to encourage the proliferation of these
provisions that will lead them to have a relative surplus number of provisions. This will
facilitate their entrenchment within the firm. On the other hand, management that are more
focused on maximizing shareholder wealth will not need to employ these provisions to
mitigate disciplinary takeovers, likely leading to the employment of fewer provisions
relative to its peers.
32
By examining the relative number of provisions a firm has, we show that it has a
significant relationship with takeover likelihood. Whereas the prior literature does not find
strong evidence of an association (Core et al., 2006), we find an inverted U-shaped
relationship exists where firms that have either a relative surplus or deficit number of
provisions are less likely to be targeted. In the former case, we argue that this is because the
board and management are acting in the interest of shareholders, whereas in the latter case
it is due to them successfully entrenching their positions. Additionally, we demonstrate that
by focusing on the relative number of provisions a firm has, as opposed to the absolute
number, it can also determine whether the firm is likely to experience a hostile takeover.
We also examine whether the inclusion of a specific provision for classified boards will
have a detrimental impact on firm value and takeover likelihood. In alignment with our main
hypothesis, we find that only for firms with a strong takeover avoidance culture (high
Relative E-Index) do we see that the presence of a classified board provision leads to a
decline in firm value and rise in takeover likelihood.
Overall, our results suggest that it is important to capture the takeover avoidance
culture of the firm. Whether ATPs have a positive or negative impact will be dependent on
the view that the board and management have towards shareholder wealth creation versus
the desire to entrench their positions. It may therefore be beneficial for future research to
explore additional dimensions of board and management attitude to better understand the
market for corporate control.

Table I Descriptive statistics of target and non-target firms
In this table we report descriptive statistics for our full sample, non-target sample (i.e. firms not subject to a takeover contest) and target sample (i.e. firms subject to a takeover
contest) of firms. In column diff, differences in Mean values between non-target and target firm variables are reported. Reported P-values are based on a one-sided univariate
t-test. Variable definitions are provided in Appendix A.

Table III Descriptive statistics of corporate control transactions
Initial bid deal characteristics for our sample of firms are reported below. % of Firms Targeted
represents the proportion of firms in our sample that receive a takeover bid. Initial Bids Completed
is an indicator variable that is set to one if the initial bid is completed, and zero otherwise.
Transaction Value is the deal dollar value as reported by SDC Platinum. Target run-up is the
summation of cumulative abnormal returns over a ten day event window as defined in Appendix
A; Bid Premium is based on cumulative abnormal returns over an event window that begins (ends)
five days before (after) the initial bid announcement date and is further defined in Appendix A; All
Cash Bid is an indicator variable set to one if the method of payment is all cash, and zero otherwise;
All Stock Bid is an indicator variable set to one if the method of payment is all stock, and zero
otherwise; Mixed Payment is an indicator variable set to one if the method of payment has both a
stock and cash component, and zero otherwise. Toehold Flag is a binary variable set to one if the
acquiring firm has a toehold (defined as a holding of 5% or more at the bid announcement date),
and zero otherwise; Target Termination Fee is an indicator variable set to one if a target termination
agreement has been initiated between the bidder and target, and zero otherwise; Hostile Bid is set
to one if SDC flags the deal as hostile, and zero otherwise; Tender flag is a binary variable set to
one if the deal is a tender offer, and zero otherwise.

Table V Multivariate results for firm value.
In this table we report OLS regression results for industry adjusted Tobin’s Q on our variables that capture unwarranted
provisions. The Relative E-Index and Relative E-Index Squared variables, used in regressions (3) and (4), proxy for
management attitude and are derived from the residual of equation (1) defined in section III.B. In regressions (5) and (6),
a one-to-one propensity score matching (PSM) procedure was used to construct a pool of peer-matched firms. Using
propensity scores derived from a logistic regression, low E-Index firms (E-Index is below the median E-Index) were
matched with high E-Index firms (E-Index is above the median E-Index). Firms with no successful match (i.e. the
difference in propensity scores exceeded a calliper of 0.01 standard deviations) were dropped from the sample. Using this
sample of peer-matched firms, we postulate that any remaining differences between low and high E-Index firms are due
to variations in management attitudes. Variable definitions are reported in Appendix A. Industry and year fixed effects
are included in all regressions. Robust standard errors clustered by industry, based on the Fama and French (1997) 12
industry classification scheme, are reported in parentheses. Significance levels are denoted by *, **, and *** for the 10%,
5% and 1% levels, respectively.

Table VI Multivariate results for the probability of being a takeover target.
In this table we report the results of probit regressions that model the likelihood of a firm being targeted. The dependent
variable in models (1) – (3) is set to one if during the year a firm is subject to a takeover contest, and zero otherwise. The
Relative E-Index and Relative E-Index Squared variables, used in regressions (3) and (4), proxy for management attitude
and are derived from the residual of equation (1) defined in section III.B. In regressions (5) and (6), a one-to-one
propensity score matching (PSM) procedure was used to construct a pool of peer-matched firms. Using propensity scores
derived from a logistic regression, low E-Index firms (E-Index is below the median E-Index) were matched with high E-
Index firms (E-Index is above the median E-Index). Firms with no successful match (i.e. the difference in propensity
scores exceeded a calliper of 0.01 standard deviations) were dropped from the sample. Using this sample of peer-matched
firms, we postulate that any remaining differences between low and high E-Index firms are due to variations in
management attitudes. Variable definitions are reported in Appendix A. Industry and year fixed effects are included in
all regressions. Robust standard errors clustered by industry, based on the Fama and French (1997) 12 industry
classification scheme, are reported in parentheses. Significance levels are denoted by *, **, and *** for the 10%, 5% and

Table VII. An instrumental variables approach for the probability of being a takeover target.
In this table we report the result for takeover likelihood and Relative E/Relative E2 where Relative E/Relative E2 is instrumented by the Sharkansky Score to address endogeneity
concerns. For the Relative E-Index, OLS first stage regression results are reported in models (1) and (3) where the dependent variables are Relative E and Relative E2, respectively. The
predicted values for Relative E and Relative E2 (derived from models (1) and (3)) then enter as independent variables in probit models (2) and (4) to instrument for Relative E and
Relative E2, respectively. The dependent variable used in models (2) and (4) is binary and set to one if the firm is targeted and zero otherwise. For the PeerMatchedDiff approach, first
stage OLS regression results are reported in models (5) and (7). The predicted values of E-Index and E-Index2 then enter as Instrumented Relative E and Instrumented Relative E2 in
probit models (6) and (8). The dependent variable in models (6) and (8) is binary and set to one if the firm is targeted and zero otherwise.

Table IX Probability of experiencing a hostile bid reception
In this table we report the 2nd stage Heckman Probit Model results where the dependent variable is probability of
receiving a hostile bid (as defined by SDC). To control for the likelihood of a firm being initially targeted, we model
the likelihood of receiving a takeover bid in the 1st stage regression. The first stage regressions are reported in Table VI
and align with the model numbers given below. To ensure the 2nd stage regressions are correctly identified, deal-specific
characteristics are included in the second stage regressions (Toehold, All Cash Payment and Tender Bid) but not in the
first stage.

Table XII Multivariate results for bid premiums and takeover contest returns using the two-stage
Heckman selection model
In this table we report the results for examining bid premiums and takeover contests from using the two-stage Heckman
selection model to control for self-selection bias. The dependent variable is initial bid premium as defined in Appendix A.
Ln(MktCapt-42) is the market capitalization of the target firm 42 days prior to the initial bid announcement date. All other
variables are defined in Appendix A. The inverse Mills ratio is derived from the first stage probit regression that estimates
the likelihood of a takeover bid materializing (see Table VII). In the second stage OLS regressions (reported below), the
inverse Mills ratio is included to ameliorate the selection bias. Significance levels are denoted by *, **, and *** for the
10%, 5% and 1% levels, respectively.

Table X Firm value and Classified boards
OLS regressions modelling the relationship between firm value and the classified board provision are
reported below. The dependent variable is industry adjusted Tobin’s Q. In model (1) the full sample of
firms are used. In models (2) and (3) we group firms into low and high Relative E-Index firms,
respectively. If the Relative E-Index of a given firm is less than the industry median Relative E-Index,
it is defined as a Low Relative E-Index firm. Similarly, if the Relative E-Index of a given firm is greater
than the industry median Relative E-Index, it is defined as a High Relative E-Index firm. Standard errors
are clustered by industry.

Table XI Takeover Likelihood and Classified Boards
Probit regressions modelling the likelihood of a firm being targeted are report below. The dependent
variables are set to one if the firm is targeted in a given year, and zero otherwise. In model (1) the full
sample of firms are used. In models (2) and (3) we group firms into low and high Relative E-Index
firms, respectively. If the Relative E-Index of a given firm is less than the industry median Relative E-
Index, it is defined as a Low Relative E-Index firm. Similarly, if the Relative E-Index of a given firm is
greater than the industry median Relative E-Index, it is defined as a High Relative E-Index firm.

Appendix Variable Definitions
Except where noted, all variables are constructed using one year lagged values to mitigate issues
associated with a look-ahead bias. All variables are also winsorized at the 1% and 99% levels.
Variable Name Definition
Firm-level Control Variables
Book Value Natural logarithm of total assets.
Ln(Market Capitalization) Natural logarithm of market capitalization, where market
capitalization is based on the average monthly market cap over
the current fiscal year.
Sales Growth Percentage increase in sales over the previous fiscal year.
Return On Assets Earnings before interest and tax (EBIT) divided by total assets.
Free Cash Flow Summation of net income plus depreciation and amortization
minus capital expenditure, divided by total assets.
Intangible Assets One minus the ratio of property, plant and equipment to total
assets.
Leverage Book value of debt divided by book value of assets.
Tobin’s Q Market value of assets divided by book value of assets, where
market value of assets is defined as book value of assets minus
book value of equity plus the market value of common stock at
the fiscal year end.
Firm Age The number of years that have elapsed since first appearing on
Compustat.
Industry Concentration Based on the Herfindahl-Hirschman Index.
Blockholder An indicator variable set to one if an institutional investor holds
5% or more of a company’s common stock, and zero otherwise.
CEO and Chair Characteristics
Ln(Cash Compensation) Defined as the natural logarithm of a CEO’s cash (salary +
bonus) compensation for a given fiscal year.
CEO Chair Duality Indicator variable set to one if the CEO is also the chairperson in
the current fiscal year, and zero otherwise.
CEO Age CEO Age is reported on Execucomp. If CEO Age is missing,
Capital IQ is then used to fill in missing observations (where
possible).
CEO Tenure CEO Tenure is a count variable where it represents the number
of years a CEO has been at a given firm. This variable is
constructed using data from Execucomp and Capital IQ.
50
Board Size Board size is a count of all directors on a firm’s board in a given
fiscal year.
Board Ownership Percentage of outstanding shares owned by the board of directors
in the current fiscal year.
Board Independence Percentage of board members that are classified as independent
directors in the current fiscal year.
Missing Board Flag Indicator variable set to one if board data is missing in the current
fiscal year, and zero otherwise.
Deal Characteristics
All Cash Indicator variable set to one if method of payment is all cash, and
zero otherwise.
All Stock Indicator variable set to one if method of payment is all stock,
and zero otherwise.
Mixed Payment Indicator variable set to one if method of payment has both a
cash and stock component, and zero otherwise.
Toehold Indicator variable set to one if the bidding firm owns 5% or more
of the target firm’s common stock on the bid announcement date,
and zero otherwise.
Target Termination Fee Indicator variable set to one if a target termination payment is
applicable, and zero otherwise.
Hostile Bid Indicator variable set to one if the bidder is hostile (based on
SDC’s classification), and zero otherwise.
Tender Indicator variable set to one if the deal is a tender offer, and zero
otherwise.
Target Run-Up
This is defined as the summation of cumulative abnormal returns
over a ten day event window starting 11 days prior to the initial
target bid announcement. The market model parameters that are
used to infer abnormal returns is estimated using a 100-day time
period beginning 152 days prior to the initial announcement of a
takeover bid. For more details regarding the event study
methodology used in this paper, please refer to MacKinlay
(1997).
Bid Premium
Target firm bid premiums are based on cumulative abnormal
returns over an event window that begins (ends) five days before
(after) the initial bid announcement date. The time period we use
to estimate the market model parameters begins (ends) 152 days
(42 days) prior to the initial bid announcement date. For more
details regarding the event study methodology used in this paper,
please refer to MacKinlay (1997).
