NEDERLANDSTALIGE SAMENVATTING
Deze thesis situeert zich in het kader van corporate governance. Door de schandalen in het begin van
het millenium, de financiële crisis en de steeds meer dynamische omgeving waarin bedrijven zich
bevinden, neemt de nood aan diversiteit binnen de raad van bestuur toe. Het doel van deze thesis is
dan ook een analyse van de mix aan profielen binnen de raad van bestuur in een Europese setting.
Het eerste grote luik bestaat uit twee delen: corporate governance en diversiteit. Er bestaan
verschillende definities van corporate governance en deze thesis focust op de ruimere definities die
ook andere stakeholders buiten de aandeelhouders beschouwen. De verschillende modellen, functies,
wetgevingen en diversiteitsvariabelen betreffende de raad van bestuur worden besproken en
vergeleken voor België, Frankrijk, Spanje en het Verenigd Koninkrijk. Deze thesis splitst diversiteit op
in ‘variëteit’ (variety), ‘scheiding’ (separation) en ‘ongelijkheid’ (disparity) (Harrison&Klein, 2007) en
legt de focus op de voordelen die diversiteit, als variëteit, biedt. De conclusie is dat er in de literatuur
geen concensus is betreffende de impact van diversiteit op de raad van bestuur. Bovendien, diversiteit
heeft zowel voor- als nadelen. De voordelen zijn betere beslissingsvorming en betere toegang tot
middelen, de nadelen zijn tragere beslissingsvorming en verminderde slagvaardigheid.
Het tweede luik is de empirische studie. Gegevens voor 1982 leden van de raad van bestuur werden
verzameld die allen in de BEL 20, CAC 40, IBEX 35 of FTSE 100 zetelden eind 2014. De toegevoegde
waarde van deze thesis ligt bij het toevoegen van functionele achtergronden en studies van de leden
van de raad van bestuur aan de analyse, alsook de grootte van de steekproef. Gezien de descriptieve
aard van het onderzoek en de veelheid aan kruistabellen is het helaas onmogelijk om alle resultaten
hier reeds te vermelden. Voor de overige resultaten verwijs ik naar het empirische luik en de conclusie.
Zowel de corporate governance codes als de resultaten in dit onderzoek wijzen op een grote
meerderheid van niet-uitvoerende bestuurders, wat de ‘agency theory’ ondersteunt, en de
‘stewardship theory’ tegenspreekt. België en het Verenigd Koninkrijk begrijpen het belang van
internationale profielen binnen het bestuur. Frankrijk doet het vooral goed op vlak van
genderdiversiteit en heeft in mindere mate internationale profielen binnen de raad van bestuur.
Spanje lijkt vast te houden aan het ‘old boys’ netwerk’, wat vrouwen ervan weerhoudt in de raad van
bestuur te zetelen. Financiële profielen zijn het meest abundant. De financiële sector heeft een
schrikwekkend lage waarde voor de Blau’s index in vergelijking met andere industrieën: dit wijst op
weinig diversiteit in functionele achtergronden. Voor de resultaten omtrent de andere industrieën
verwijs ik naar het empirische luik en de conclusie.

FOREWORD
When writing this dissertation, the final result of two years of hard work, I received support from many
angles and therefore want to express my gratitude to some people.
Firstly, I want to thank Prof. Abigail Levrau for giving me the opportunity to write this dissertation in
the field of corporate governance. Her expertise in the field of corporate governance was invaluable
to me. I want to thank her for the support, feedback and guidance I received, but most of all I want to
say thank you for constantly motivating me and believing in me.
Secondly I want to thank Annelies De Wilde, Research Associate at GUBERNA and dr. Olivier Van der
Brempt, Doctoral Associate at GUBERNA for allowing me to bore them with my questions. Thank you
for the valuable opinions.
I also want to thank my partner Emiel for constantly supporting me and encouraging me. Lastly, I want
to thank my parents, sister Sarah and brother Jan for the encouragement and support I continuously
received during the writing of this thesis, and the five years of studying preceding it.

1 Introduction
Corporate governance plays an important role as a safeguard for preventing malpractices, although it
did not prevent the accounting frauds in the beginning of the century (Enron, Ahold and Parmalat).
Neither did corporate governance prevent the financial crisis. Due to these unfortunate happenings,
corporate governance has continued to gain interest (Heidrick & Struggles, 2014).
There is growing interest for the boards to be more diverse (ICAEW, 2014), as “the board is responsible
for the standing of their company in the community” (Levrau & Van den Berghe, 2004, p.462). Although
literature has extensively discussed board diversity, literature has yielded ambiguous results towards
the impact of diversity on board performance. Harrison & Klein (2007) believe the problem lays in
defining diversity too broadly. I will therefore continue to build on the distinction of diversity the
authors make into variety, separation and disparity with the aim of producing a more clear view on the
mix of profiles sitting on the board.
Several corporate governance codes mention the importance of the mix of qualities the board should
consist of, though very little research has actually been done on the qualities or backgrounds
concerning these directors. The added value of this dissertation definitely stems from the large sample
and from including the variables functional background and educational background to board
literature’s widely discussed diversity variables such as gender, (non-) executive, independent, age,
board size, etc. As this dissertation scrutinizes board diversity, it is clear that this dissertation is situated
in the field of corporate governance.
The dissertation consists of several parts: literature study (2), methodology (3), empirical study (4) and
conclusion (5). The literature study consists of two large parts: corporate governance and diversity.
The first part of the literature study gives different views on corporate governance, as it is a widely
discussed topic and can be viewed from different angles. The focus of this dissertation is on definitions
that include other stakeholders than stockholders, as the company nowadays is active in a dynamic
world (Heidrick & Struggles, 2014). The board’s models, roles and members will be extensively
discussed with the aim of understanding the diversity challenge the board faces. Several board
diversity variables will be addressed, as well as quota for these variables, described by soft law, hard
law or corporate governance codes.
![Page 15: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/15.jpg)
2
The second part of the literature study concerns diversity. Board diversity has yielded ambiguous
results on performance, which is why this dissertation continues to build on the three dimensions
Harrison & Klein (2007) believe diversity covers. The focus will be on variety. Much research has
already been done on board diversity, especially concerning gender diversity, but few research has
investigated the actual mix of profiles concerning educational or functional backgrounds of the board.
When discussing functional background the link is made to TMT literature, although it must be argued
that the board is different from an organizational team (Levrau & Van den Berghe, 2007).
The third part, the methodology, describes the setting of the research, how the sample was chosen
and how the data was collected and analysed. It is followed by the empirical study, the fourth part.
Banks were excluded from the sample because many regulations already determine the mix of profiles
within their boards. A lot of attention is given to the categories that were chosen to classify companies
and directors. Several cross-tabulations are performed on the database which I personally built and
results are given. Part five ends with the conclusion, limitations and opportunities for further research.
It must be clear to the reader that this dissertation tries to answer the question “What is the mix of
profiles within the boards?” and the reader should thus note that this dissertation does not try to
measure the impact board diversity has on performance. The aim of this dissertation, however, is to
make a cartography of the profiles within the board of directors within their environment, of top-listed
companies within Belgium, France, Spain and the UK. This dissertation tries to provide a more clear
view on who exactly sits on the boards of listed companies in a European context. Because few
research has been done on functional and educational backgrounds of board directors, both aspects
of diversity as variety, this research is rather exploratory towards diversity as variety, making a
cartography, rather than hypothesis testing. Again, the added value of this dissertation clearly stems
from including the diversity variables functional and educational background to ‘the mix’ when
performing several cross-tabulations. Nonetheless, many board diversity variables are taken into
account as well to determine the mix of profiles on the board.
Finally, I hope that including the functional backgrounds and educational backgrounds of board
members can, in practice, contribute to a deeper understanding of the mix of profiles sitting on these
boards, and contribute to the understanding of board diversity, rather than making results more
ambiguous. The next step is to link these findings to board performance.

2 Literature study
2.1 Corporate governance
2.1.1 Introduction
As corporate governance is a very broad topic this dissertation will start with some definitions on
corporate governance and situate them within existing theories. Next the importance of corporate
governance will be highlighted, followed by an elaboration on the board of directors, its models and
its roles. This chapter ends with regulations, guidelines and codes on corporate governance and the
board of directors and its diversity variables.
2.1.2 Definition
Several definitions of corporate governance exist. A first, most basic and traditional, definition of
corporate governance is the following: corporate governance deals with problems resulting from
separating ownership and control (Berle & Means, 1933). Because of the separation between
ownership and control, managers could pursue their own goals at the expense of the shareholders.
This definition can be situated in the agency theory, which is concerned with the agency relationship
between an agent and a principal: one the one hand there is the management that controls the
company (agent) and on the other hand there are the shareholders who own the company (principal).
“Corporate governance involves a set of relationships between a company’s management, its board,
its shareholders and other stakeholders. Corporate governance also provides the structure through
which the objectives of the company are set, and the means of attaining those objectives and
monitoring performance are determined” (OECD Principles of Corporate Governance, 2004, p.11). This
broader definition, in contrast to the previous traditional definition, also includes other stakeholders
than the management and shareholders. The board should not only take other stakeholders into
account, but also let them participate in the board, as Hung (1998) said: corporations are more likely
to respond to the interests of society as a whole, instead of only to the interests of shareholders, by
incorporating the participation of stakeholders in the governing boards. It seems more appropriate to
use this wide definition, also including other stakeholders, looking back at the financial crisis.
Other authors that agree on this contrast concerning the traditional focus on the agency theory and
acknowledge the importance of other stakeholders are Heidrick & Struggles (2014). They say that
nowadays the board is also active in dynamic governance and has to be connected with society raising
the importance of all stakeholders. The authors argue that corporate governance should anticipate to
![Page 17: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/17.jpg)

what is happening out there in the business world and should embrace change and create flexibility in
this dynamic world. Once again, quite the opposite of what was happening during the financial crisis
when some signs were clear, however no actions were taken until it was already too late (Kirkpatrick,
2009).
Schleifer and Vishny (1997, p.737) focus on a more juridical point of view on corporate governance,
and pay special attention to legal protection of the investors and how they prevent managers from
using their investments for their own purposes: “Corporate governance deals with the ways in which
suppliers of finance to corporations assure themselves of getting a return on their investment.”
In contrast to the latter, more juridical point of view, Heidrick & Struggles (2014, p.2) point out the
following: “It is important that corporate governance does not become a one size fits all compliance
exercise”. They put forward the view that corporate governance should not me regarded as an act of
compliance that has to be fulfilled but as engagement.
Though all aforementioned definitions on corporate governance are relevant, this dissertation will
predominantly focus on those definitions that are concerned with diversity, and thus include
stakeholders.
2.1.3 Importance
At the beginning of the century several accounting frauds were discovered. The energy company Enron
went bankrupt in 2001 and the worldom scandal was discovered in 2002. But the scandals were not
limited to America. On February 27th of 2003 The Economist called the Ahold scandal ‘Europe’s Enron’
and blamed corporate governance. In September 2003 The Guardian published an article named
‘Parmalat is Europe’s Enron’ and once more shares dropped as a result of malpractice. Corporate
governance was once more to be blamed because of poor performance: it did not prevent certain
malpractices (Kirkpatrick, 2009).
The financial crisis of 2007-2008 is another example of failure of corporate governance. Accounting
standards and regulatory requirements still proved to be insufficient (Kirkpatrick, 2009). During the
financial crisis enormous risks were taken but were poorly controlled, though the OECD Principles
make risk management a clear duty of the board (Kirkpatrick, 2009). Corporate governance had failed
once again.

Due to all these malpractices and the events during the financial crisis, corporate governance has
continued to gain interest: regulations, standards and initiatives rose (Heidrick & Struggles, 2014) as
an attempt to make companies more accountable for their actions, improve access to capital and make
them operate more efficiently. Corporate governance continues trying to be a safeguard to prevent
mismanagement (IFC, 2013), and there is a growing interest for the boards to be more diverse (ICAEW,
2014).
2.1.4 The Board of directors
The board of directors is a body of members who govern the firm and who have ultimate decision-
making authority. From an agency theory perspective the board is an internal control mechanism that
copes with divergences in interests between managers and shareholders and make them converge
(Walsh & Seward, 1990). As the board of directors is essential to most definitions of corporate
governance (Maassen, 2002), it is important to know the different models. Literature distinguishes two
different models: the one-tier board model and the two-tier board model.
In Belgium the one-tier board model is the standard. By contrast, in credit institutions and insurance
companies the dual board system is obligatory because the management requires autonomy to serve
the public interest (Davies, Hopt, Nowak & Solinge, 2013). In France, companies can adopt both the
one-tier or two-tier model, although the one-tier model is the model on which French company law
was based. This model uses the board of directors (conseil d’administration). The dual board model
consists of a supervisory board (conseil de surveillance) and managing board (directoire) (Davies, Hopt,
Nowak & Solinge, 2013). In Spain, the one-tier system is adopted. The two-tier model is only used in
European public companies incorporated in Spain (Davies, Hopt, Nowak & Solinge, 2013). In the UK,
companies opt for the one-tier system.
2.1.4.1 Classification of directors
There are three sorts of directors: executive, non-executive and independent directors. These
classifications can be treated as diversity variables within the board: the first variable being executive
or non-executive, and the second variable being independent or not.
The first, executive director, has more in-depth knowledge. He is valuable to the board because he
knows the company and its operations (Davies, 1999). Many non-executive directors join the board
after having been an executive director, to further fulfil the strategic role (see 2.1.4.4.2).
![Page 19: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/19.jpg)
6
The second, non- executive director, sits on the board because he has wide expertise and experience
to contribute. Furthermore the non-executive directors can monitor the performance of the executive
directors and management (Davies, 1999).
Thirdly, directors can be independent. An independent director is always a non-executive director.
Definitions on ‘independent’ vary yet converge towards a stricter meaning of the word (Hopt & Leyens,
2004). In general, independent directors are supposed not to have any relationship with the
corporation. The several existing country-specific corporate governance codes elaborately explain
when a board member can be named independent.
Some countries add a fourth diversity variable: directors who represent employees. In this dissertation,
this only concerns France. Employees can be represented by one or more employee representatives,
if the by-laws provide this option, as written in the AFEP/MEDEF code.
Over the last few years, the proportion of (non-executive) independent directors is gaining more
importance. The focus used to be on the mix of executive and non-executive directors. To date, the UK
code of corporate governance doesn’t even mention anything about the mix of (non-)executive
directors anymore (Davies, Hopt, Nowak & Solinge, 2013).
The board also has to appoint an audit, remuneration, and nomination committee, for which the
corporate governance codes also provides guidelines, but this dissertation will not elaborate further
on the specific committees.
2.1.4.2 One-tier board model
The one-tier board model or unitary board system is adopted in the UK, Belgium, Spain, Canada and
the US (non-exhaustive). In this model both executive- and non-executive directors can sit on the
board. This means that the board is entrusted with both day-to-day business and control of the
business. Because both executive and non-executive directors can sit on the one-tier board, ‘(non-)
executive’ will be a variable of diversity within this model.
2.1.4.3 Two-tier board model
In other countries, Germany and the Netherlands for example, the two-tier board system or dual board
system is adopted. This model distinguishes two layers: the supervisory board and the management
board.
![Page 20: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/20.jpg)
7
The supervisory board is the upper layer of the board and is composed of non-executives only. The
main legal functions of this board are the appointment, supervision and removal of members of the
management board. Although executives are not allowed to have a seat on the supervisory board,
former executives are allowed to have a seat on the supervisory board and many companies try to
make use of former business knowledge by offering former managers seats on the board (Hopt &
Leyens, 2004).
The management board, which is the lower layer, is composed of executive managing directors
(Maassen, 2002). Directors sitting on the management board have executive functions by definition.
However this doesn’t necessarily mean that they are employees of the company (Davies, Hopt, Nowak
& Solinge, 2013). Internal control is an instrument of the management board from which the
supervisory board is excluded (Hopt & Leyens, 2004).
It must be said that one-tier systems try to solve the lack of a two-tier system. They strive for more
transparent division of tasks and allocation of responsibilities through a majority of independent
directors and at least a majority of non-executive directors in the committees (remuneration,
nomination and audit committees). This may compensate for the disadvantages of the unitary board
system (Davies, Hopt, Nowak & Solinge, 2013).
2.1.4.4 The roles of the board of directors
This paragraph discusses the roles of the board. It starts with discussing the three main roles that we
typically find in board literature: monitoring role, strategic role and service role (Zahra & Pearce, 1989),
followed by an elaboration on the coordinating role as described by Hung (1998).
2.1.4.4.1 The monitoring role
The monitoring role or controlling role is based on the agency theory and thus on the fact that the
board has to govern the relationship between the owners and management of the company. The board
has to protect the interests of shareholders and make sure that the management does not act in their
own interest and solve problems resulting from separation from ownership and control (Berle &
Means, 1933). Translated into a diversity variable, the (independent) non-executive directors can
monitor this performance and good behaviour of the executive directors (Brennan & McDermott,
2004). According to Zahra & Pierce (1989) the board has the following duties: selecting and replacing
the CEO, monitoring the CEO’s performance and also evaluating the company’s performance. In Demb
![Page 21: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/21.jpg)
8
& Neubauer (1990) their research corporate directors often commented that even the mere existence
of a board and the obligation to report, results in better performance.
2.1.4.4.1.1 Agency theory
Opening up corporate ownership to the public through share ownership is what caused the separation
of ownership and control. Because of this separation of ownership, incentives exist for managers to
act in their own interests and not necessarily in the interest of the owners (Solomon, 2007). It is
important to control these agency problems when the managers, making important decisions, are not
the major claimants and therefore do not benefit in the wealth of those decisions (Fama & Jensen,
1983). It is up to the board to deal with these divergent interests and attempt to reduce the manager’s
opportunism (Hung, 1998).
2.1.4.4.2 The strategic role
Demb & Neubauer (1990, p.157) highlight the importance of involvement of the board in corporate
strategy: “Primarily through involvement in corporate strategy, boards can play a forward-looking role,
adding value by utilizing its breadth of experience”. Goodstein, Gautam & Boeker (1994, p.242) put
forward that the strategic role of the board “involves taking important decisions on strategic change
that help the organization adapt to important environmental changes”. The authors also argue that
critical periods of environmental turbulence or declines in performance provide opportunities for
initiation of strategic change.
However literature shows no consensus on how active the board of directors should be in strategy.
Zahra (1990) distinguishes three different schools. The first school argues the board should not be
actively involved in strategy and should merely act as the ‘rubber stamp’. According to the second
school the board should be active in strategy review: they should be involved in formulating and
implementing strategies, although they should not develop new strategies. Thus they may recommend
making changes and refinements in company strategies but not develop them themselves. Actually
proposing, initiating and developing strategic changes are part of the third school which goes far
beyond the control function of the board. The strategic role finds its rationale in the stewardship
theory.
![Page 22: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/22.jpg)

2.1.4.4.2.1 Stewardship theory
As opposed to the agency theory, the stewardship theory rejects the role of the board to cope with
conflicts resulting from separation from ownership and management. On the contrary, it believes the
board to serve as a strategic device that can serve the company through active involvement and
expertise (Levrau & Van Den Berghe, 2007). Thus, the stewardship theory does not recognize
differences in interest between management and ownership and assumes that managers actually want
to act in best interest of the company (Hung, 1998). Translated into board diversity, executive directors
thus act in the best interest of the company, and non-executive directors and/or independent directors
thus attribute their expertise and knowledge to that of the executive directors to help strategic
decision-making and to increase the quality of decision-making (Muth & Donaldson, 1998).
2.1.4.4.3 Service role
According to Zahra & Pearce (1989, p.292) “the service role involves enhancing the company’s
reputation, establishing contacts with the external environment and giving counsel to executives.”
Mintzberg (1983) distinguishes another role: co-opting external influencers. The service role, which
concerns establishing contacts with the external environment, can be compared to Hung’s (1998)
linking role. When a board member sits on the board of two different organizations these organizations
are related by an ‘interlock’. These interlocks are very important to tap into pools of resources (Hung,
1998). The service role finds its rationale in the resource dependence theory.
2.1.4.4.3.1 Resource dependency theory
The resource dependence theory was first described by Pfeffer & Salancik (1978): external resources
can affect the behaviour of an organization in a way that they depend on the providers of these
resources. Organizations depend on their environment because they are not self-sufficient.
Furthermore companies try to be independent of other companies while making other companies
dependent on them. The four benefits or resources that Pfeffer and Salancik (1978) suggest that
directors of the board bring to the organization are advice and counsel, access to channels of
information flow, preferential access to resources and legitimacy. These benefits have found a lot of
support (Hillman, Withers & Collins, 2009) in literature. Hillman, Withers & Collins (2009) their research
even shows that empirical evidence suggests that the resource dependence theory is more successful
for understanding boards than the traditionally used agency theory, though the resource dependence
theory is less often used.
![Page 23: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/23.jpg)

Concerning diversity within the board, the focus of this dissertation, one of the tasks of the board of
directors in order to optimize the organizations performance is, to act as an essential link between the
organization and resources (Van der Walt & Ingley, 2003). A more diverse board will have a broader
network and a broader pool of resources to tap into. The sort of directors that plays the most important
role in the resource dependency theory are the independent directors, as they have no relationship
with the company and create links with the external environment of the company.
2.1.4.4.4 Coordinating role
“The company, whether it wishes or not, is held accountable for its actions by numerous and varied
groups of stakeholders, and the public” (Demb & Neubauer, 1990, p.158). The coordinating role is
situated in the stakeholder theory and will be scrutinized in the next paragraph.
2.1.4.4.4.1 Stakeholder theory
The stakeholder theory is situated in sociology and is used to describe interactions between
organizations and their environments (stakeholders). The underlying argument is that the organisation
is not only responsible to the stockholders, but also to many other groups such as customers, banks,
environmentalists, etc. According to this theory the organization will fulfil its coordinating role by
negotiating and compromising with stakeholders in their own interest (Hung, 1998). From this
perspective “corporations are seen as superordinate entities in which a variety of parties have vested
legitimate interests” (Maassen, 2002, p.13): the board must thus reflect its stakeholders in order to
protect its stakeholder’s interests.
I have opted to add the coordinating role and stake holder theory because they address diversity within
the board and are therefore important to this dissertation. In order for the board of directors to be
responsible to the stakeholders, the adequate information to make decisions regarding these
stakeholders should be present during the board meetings: a diverse board of directors will dispose of
diverse information and thus be able to make decisions that reflect stakeholders’ interests.
2.1.5 Laws, regulations and guidelines.
In this paragraph we will take a closer look at existing laws, regulations and guidelines concerning
corporate governance on two levels: international and national. Corporate governance seems to be
continuously gaining importance and thus several laws, regulations and guidelines are volatile and
under continuous revision.
![Page 24: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/24.jpg)

It is important to first explain the difference between soft law and hard law. While hard law arises from
treaties or regulations, soft law lacks obligation or uniformity and is not formally binding. While soft
law is argued not to have any effect, hard law on the contrary is argued to be too difficult to change
and too fixed (Trubek, Cottrell & Nance, 2005). Although soft law is not formally binding it is assumed
to have this effect in the long term and is thus potentially binding (Hillgenberg, 1999). A balance
between soft law and hard law can be more flexible to adapt to the constantly changing environment
of a company and maybe be more effective. This is why the European Union governance codes are
backed by the “comply-or-explain” approach, the trademark in the EU (CNMV, 2015). The “comply-or-
explain” means that companies can deviate from governance codes if they explain why they deviate
from this code and tries to create flexibility.
2.1.5.1 International Level
2.1.5.1.1 Sarbanes Oxley
The Sarbanes-Oxley Act does not apply to the examined countries (Belgium, France, Spain, and the
United Kingdom), but has played a major role in corporate governance in the USA. This Act came into
force in 2002 and is mandatory for all organizations, changing regulations concerning corporate
governance: “ALL organizations, large and small, MUST comply” (Sarbanes-Oxley Act, 2002). This act
mainly consists of compliance of several acts and is rather strict. The act strengthened audit
committees (independence requirements1) and also strengthened disclosure requirements.
2.1.5.1.2 OECD Principles of Corporate Governance
The OECD Principles of Corporate Governance are widely accepted by both OECD and non-OECD
countries, and are non-binding (soft law). They are meant as a reference point. The following definition
is given by the OECD (2004, p.11): “The principles are intended to assist OECD and non-OECD
governments in their efforts to evaluate and improve legal, institutional and regulatory framework for
corporate governance in their countries, and to provide guidance and suggestions for stock exchanges,
investors, corporations and other parties that have a role in the process of developing good corporate
governance. The Principles focus on publicly traded companies, both financial and non-financial”.
Furthermore the Principles of Corporate Governance (2004) acknowledge corporate governance as “a
key element in improving efficiency and growth as well as enhancing investor confidence.” The latter

has without doubt gained importance due to the financial crisis. Concerning board diversity, the
G20/OECD Principles of Corporate Governance (2015) mention that groupthink should be avoided and
the board should possess the right mix of backgrounds and competences.
2.1.5.2 National Level
In what follows we will zoom in on the different laws, regulations and corporate governance codes
within the countries included in the sample of this dissertation. For each country we will also address
some board characteristics concerning diversity variables.
2.1.5.2.1 Belgium
Corporate governance in Belgium has two main legal sources: the Belgian Companies Code and the
corporate governance code 2009 (Davies, Hopt, Nowak & Solinge, 2013).
The Belgian corporate governance code, the only reference for listed companies in Belgium by Royal
Decree of 6 June 20102, is the 2009 Code and complements the Code on Belgian law. It is an update on
its predecessor, referred to as the 2004 Code, and is based on voluntary compliance recommendations.
In contrast to the hard law the Sarbanes Oxley Act consists of, the 2009 Code is more flexible, which is
a must in the continuously changing business world (The 2009 Belgian Code on Corporate Governance,
2009). It must be said that though the nature of the 2009 Code mainly is compliance, the BEL-20
companies are very compliant at applying this code according to a study from GUBERNA and VBO
(2011). The comply-or-explain rule is also legally binding since the Royal Decree of 6 June 20103.
2.1.5.2.1.1 Board characteristics concerning diversity: Belgium
The 2009 Code consists of several principles, provisions and guidelines to ensure good corporate
governance. Concerning diversity the code contains a few guidelines stating that the board should be
both small enough to make decisions efficiently and large enough to have a diverse mix of knowledge
and experience. Several quota are given: for example, at least 50% of board directors should be non-
executive directors and at least three of them should be independent, though none of these quota
legally binding. Since the approval of the Belgian law of 6th April 20104 listed companies are obliged by

law to include a corporate government statement in their annual report. The Belgian law of 28th July
20115 states that at least one third of the board members of government-held companies (by 2012),
publicly listed companies (by 2017) and listed SMEs (by 2019) has to be of a different sex than the
other board members (European Commission, 2013). The 2009 code also contains a guideline stating
that when composing the committee, the board should consider the qualities needed to function
optimally. According to the Spencer Stuart’s Belgium Board Index (2014) the average board size is 12.3
and the BEL 20 executive and non-executive officers have an average age of 55.5 and 58.5 respectively.
2.1.5.2.2 France
The first principles for corporate governance where published in the Vienot report in 1995. AFEP
(Association Française des Entreprises Privées) and MEDEF (Mouvement des Entreprises de France)
prepared recommendations in the years that followed. This set of recommendations constitutes de
AFEP/MEDEF Code, and has been written for unitary boards: adjustments must be made for companies
adopting the two-tier board model. Most of the listed companies in France apply the APEF/MEDEF
code (Davies, Hopt, Nowak & Solinge, 2013) and it was last revised in June 2013. The AFEP/MEDEF
code is not binding and is of the comply-or-explain principle.
Furthermore French law allows the board to choose whether the same or different persons should
hold the offices of CEO and Chairman. In good governance it is considered best to have different
persons assuming these offices and it is considered more respectful because there is a stricter division
of the managing and supervising functions (Davies, Hopt, Nowak & Solinge, 2013). In practice, we see
that more than 50% of the CAC 40 companies had elected a single person to assume both role of the
chairman and CEO in recent years (Davies, Hopt, Nowak & Solinge, 2013).
2.1.5.2.2.1 Board characteristics concerning diversity: France
The French Law of 27 January 2011 6 states that by 2017 women should represent not less than 40%
of board of directors. Regarding independent directors there are no legal obligations, although the
Vienot Report (1995) recommends a minimum number of independent directors on the board. The
AFEP/MEDEF code recommends that half (resp. at least one third) of the directors should be
independent in organizations without (resp. with) controlling shareholders. No recommendations are

14
made for non-executive directors, although the recommendations for independent directors implicitly
are recommendations for non-executive directors as well, as an independent director is per definition
non-executive. The AFEP/MEDEF code also allows for up to 5 employee representatives, elected by the
company’s employees, and advises not to take employee representatives or employee shareholder
representatives into account for these calculations. Furthermore the one-tier board should have
between three and eighteen directors and the managing board a maximum of eighteen. The number
of directors on the boards of the CAC 40 companies ranges from twelve to fourteen. (Davies, Hopt,
Nowak & Solinge, 2013). According to the Spencer Stuart France Board Index 2014, the average board
contains 14 board directors.
2.1.5.2.3 Spain
Spain strictly separates hard from soft law. On the one hand it has the binding provisions such as the
Spanish Company Law, and on the other hand it has the corporate governance recommendations
(CNMV, 2015). Starting from 1997 three good governance codes have been approved in Spain. The
first was the Olivencia Code. All companies rapidly declared their compliance with this code, as it was
not specific enough. The Aldama code was published in 2003 because of these doubtfully sincere
declarations. The Aldama code made an annual corporate governance report mandatory for listed
companies and initiated the comply-or-explain principle (Davies, Hopt, Nowak & Solinge, 2013). In May
2006 the Unified Good Governance Code of Listed Companies was approved by the CNMV (Comisión
Nacional del Mercado de Valores). It has been adapted in 2013 due to new legislation. On 18 February
2015 the Good Governance Code (The Good Governance Code of Listed Companies) was updated again
(CNMV, 2015). This governance code is also subject to the comply-or-explain approach.
2.1.5.2.3.1 Board characteristics concerning diversity: Spain
Concerning diversity the Good Governance Code (2015) suggests having a large majority of non-
executive directors. Furthermore it suggests that at least half of the board consists of independent
directors. A recommendation for the presence of women on the board is made: by 2020 at least 30%
of board members should be women. In Spain’s Boletín Oficial del Estado (2014), which consists of
hard law, it is stated that the annual report should explain which measures are taken towards equal
representation of gender within the board, however no specific objectives are given. The LSC (Ley de
Sociedades de Capital) states that the board of directors for limited liability companies should not have
more than twelve members. However, an exception is made for European public companies that have
opted for the two-tier system: they should have between three and seven members (LSC, Article
![Page 28: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/28.jpg)

481)7.The good governance code (CUBG, Código Uniforme de Buen Gobierno) recommends the
number of directors within the board to be between five and fifteen. According to the Spencer Stuart
Spain Board Index (2014) the average board consists of 11.4 board members and their average age is
59.
2.1.5.2.4 United Kingdom
British company law does not structure a one-tier or two-tier board: “The lack of interest shown by the
Companies Acts in issues of board structure, composition and function is a long-standing feature of
British Corporate law : these are matters the companies themselves should decide on” (Davies, Hopt ,
Nowak & Solinge , 2013, p.716). In practice we see that UK companies operate with the unitary board
system.
The UK corporate governance code (2014), or the Code, is the most recent version of the first UK
Corporate Governance code that was produced in 1992 by the Cadbury Committee. The Code is flexible
and consists of principles and provisions. The Code is also subject to the comply- or-explain approach.
2.1.5.2.4.1 Board characteristics concerning diversity: United Kingdom
Concerning board diversity, the UK Corporate Governance Code (2014, p. 11) states that “at least half
the board, excluding the chairman, should comprise non-executive directors determined by the board
to be independent. A smaller company should have at least two independent non-executive directors.”
As stated before it does not mention specifics on other than independent directors. Contrary to Spain,
where it is hard law that addresses equal representation of gender, measures taken should be
described, it is the UK Corporate Governance Code (2014) (soft law) that recommends to describe the
board’s policy, implementation and progress on diversity (including gender diversity). Gender diversity
was first mentioned in the Corporate Governance Code of 2010. According to the Spencer Stuart UK
Board Index (2014) the average age of non-executive directors is 59.3 years and the average executive
director is 52.4 years old. The average board size is 10.5 and 71 percent of all directors were non-
executive directors, excluding the chairmen.
It is clear that the corporate governance codes especially focus on a large majority of non-executive
directors and also independent directors, which is in favour of the agency theory and contradicts the
stewardship theory.

2.2 Diversity
In the previous part of this dissertation, some diversity variables were already addressed: (non-)
executive, independent or not, board size, and gender. First, this chapter addresses the broad concept
of diversity and highlights its importance. After that, diversity as variety within the board, followed by
functional and educational background diversity will be addressed. Some findings concerning the
diversity variables gender and (non-) national will finally also be addressed.
In order to research the diversity of the board of directors it is important to have a full understanding
of this concept. Because diversity is a widely studied and broad topic, I will explain in what follows
more specifically from which angle this dissertation addresses diversity.
It is important to note that a lot of the literature concerning diversity is situated in the field of sociology
and organizational literature. It also is important to recognize that the board of directors differs from
an organizational team in several aspects. Levrau & Van den Berghe (2007) give a nice overview of why
the board is different: partial affiliation of board members, only episodic interactions, limited time of
board members and few information to work with, preponderance of leaders, complex authority
relationships between directors, changing expectations of work, aura of formality in the board and a
large number of members. When drawing conclusions one should thus constantly keep in mind these
differences.
The past few decades, diversity became more popular in the corporate world (Page, 2007) and in
corporate governance. The UK Corporate Governance Code (2014, p.2) for example points out
“constructive debate can be encouraged through having sufficient diversity on the board”. Page (2007)
even claims that in some cases diversity trumps ability. When Page talks about diversity, he stresses
cognitive diversity: different perspectives, heuristics and different categorizations (people have
different ways of parsing the world into piles of similar things). With his Mathematical Theorem he
proves that maximum diversity should be tried to reach in order to make high quality decisions, though
of course this can’t be applied to the board as such a large number of board members would make the
board extremely inefficient and slow in its decision-making. In practice, maximum diversity as
described by Page (2007) can thus never be achieved within the boardroom, as this would imply an
enormously large, theoretically infinite, number of board members.
Several authors disagree with Page. Sunstein & Hastie (2015) for example claim that large groups can
make bad decisions and go gravely wrong because people like to hear commonly known information
![Page 30: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/30.jpg)
17
and a group becomes focused more on shared information as the group becomes larger. Thompson
(2014) claims that there are several flaws8 in Page’s Mathematical Theorem and argues that it is not
applicable in the real-world. Harrison & Klein (2007) also argue that Page has based his theory on
several wrong assumptions, and that empirical evidence for performance benefits of diverse groups in
organisations is contradictory.
Though a lot of research has been done on diversity the outcomes of these studies have been
confusing. Literature on diversity shows no consensus on its results regarding performance. Harrison
& Klein claim that these confusing and ambiguous results are due to the several dimensions that
diversity covers: variety, separation, and disparity. This definition of diversity has also been embraced
by other authors (Solanas, Selvam, Navarro & Leiva, 2012):
- Variety or information diversity refers to variety within a group of knowledge,
heuristics and perspectives and should be maximized. This aspect of diversity will be
covered more widely further in this dissertation.
- Separation is described as “the composition of differences in (lateral) position or
opinion among unit members” (Harrison & Klein, 2007, p.1203).
- Disparity is referred to as vertical differences in power or status or socially valued
assets.
The authors claim that these three distinctive types of diversity have their own consequences which
should be studied separately in order to draw clear conclusions on the effect diversity has on
performance and quality of decision-making.
On the one hand I believe there lays truth in what Page claims: in order to make well-thought, high
quality decisions one needs diversity. On the other hand one must consider the board to be different
from a team. For example, corporate governance codes recommend an optimal number of board
members to make the board efficient, which by definition limits maximal diversity. It is also true what
Harrison & Klein and Thompson state: there is no empirical evidence that embracing diversity has
already yielded remarkable results of performance.
In this dissertation I continue to build on the claim that diversity should be scrutinized more closely
and divided in variety, separation, and disparity, as suggested by Harrison & Klein (2007).
8 More information on this flaws can be found on page 1028 in “Does Diversity trumps Ability?”, published in the American Mathematical Society.
![Page 31: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/31.jpg)

There is ground to believe that that no evidence has been found due to results of different concepts
over diversity overlapping and abolishing one another. Under these circumstances I do believe that if
the board of directors is more diverse in terms of variety higher-quality decisions can be made if
simultaneously the negative outcomes from disparity and separation are minimized, as described by
Harrison & Klein (2007).
This dissertation will thus mainly address diversity as variety. In addition to the latter, I believe that the
chairman also plays an important role in the making of these high-quality decisions. After all the
chairman is leading the board, and it is up to him/her to make sure that a diverse board is able to
function. Although this is a very interesting subject it will not be addressed more thoroughly in this
dissertation.
Diversity covers many aspects and both demographic and non-demographic variables such as gender,
age, race and ethnicity, tenure, functional background, education and marital status, values, attitudes,
conscientiousness, network ties, affect, dress, individual performance, and pay (Harrison & Klein,
2007). There is reason to believe that demographic characteristics evoke prejudices, biases or
stereotypes between individuals (Harrison, Price, Gavin & Florey, 2002) reducing team performance,
however as members of a team spend more time functioning together these variables might become
less important (Harrison, Price, Gavin & Florey, 2002). However, the reader should note that within
the board these variables probably retain their importance as the board only meets occasionally.
Translated to the diversity distinction of Harrison & Klein, this means that visible characteristics as
gender, age, race and ethnicity may play an important role of diversity as separation and disparity.
Once again, separation and disparity are not the main focus in this dissertation and are to be minimized
in order to achieve performance and quality in decision-making (Harrison & Klein, 2007).
This dissertation focusses on the educational content and functional background of the members of
the board, both variables which are regarded mainly as forms of diversity as variety (Harrison & Klein,
2007) and thus contribute to higher quality decision-making. Diversity as variety will be covered in
paragraph 2.2.5. This dissertation further also takes into account the variables (non-) executive and
independent or not as these are important diversity board variables. In what follows, the board’s roles
will be discussed mainly for the diversity (non-) executive and (non-) independent.
![Page 32: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/32.jpg)
19
2.2.1 Agency theory
The agency theory is mainly concerned with the board’s monitoring role and argues that (independent)
non-executive directors should be better at monitoring the executive directors (Brennan &
McDermott, 2004). The agency theory believes that a majority of NEDs reduces the influence the
management has on the board (Muth & Donaldson, 1998) and therefore the diversity variable
executive or non-executive plays an important role in the agency theory.
2.2.2 Stewardship theory
The stewardship theory believes in the opposite of what the agency theory believes in, and is in favour
of a majority of executive directors. The executive directors provide the necessary experience and do
not have conflicts of interest with the shareholders of the company (Muth & Donaldson, 1998). It must
be argued that diversity yields both positive and negative outcomes. Though diversity within the board
of directors might lead to high quality decision making it might also slow down the pace at which
decisions are made, which might especially be important for the board’s strategic role, which finds its
rationale in the stewardship theory. The European Commission states in its green paper ‘The EU
corporate governance framework’ (2011) that “more diversity leads to more discussion, more
monitoring and more challenges in the boardroom and potentially results in better decisions although
getting to those decisions may take more time.” Goodstein, Gautam & Boeker (1994) find that diversity
may slow decisive action, especially in critical times, times of environmental turbulence, when strategic
change should be initiated. Therefore, I believe that depending on whether a more diverse board slows
down decision-making or not, it impacts the board’s strategic role differently. Especially in critical
times, diversity may have a negative impact, even if the quality of the decision-making is excellent.
2.2.3 Resource dependency theory
The resource dependency theory is concerned with the board’s service role and believes that the
broader a director’s network is, the broader the pool of resources to tap into will be, as connections
create options (Muth & Donaldson, 1998). In contrast to the previous two theories, the resource
dependency theory is not directly in favour of a majority of executive, non-executive or independent
directors but is in favour of directors with a high level of network connections, network ties.
Nonetheless I do believe that independent directors may have a different, more distant, network than
executive directors. I also believe that non-national directors probably have different networks than
national directors, and thus this may also be an important diversity variable that supports the resource
dependency theory.
![Page 33: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/33.jpg)
20
2.2.4 Stakeholder theory
Over the past decades, the definition of a stakeholder changed from “those who have a stake in an
organisation” to “those who are affected by it” (Sternberg, 1997, p.3), enormously increasing the
number of stakeholders a company has. Similarly as for the resource dependency theory, the
stakeholder theory does not favour a majority of a specific sort of director. Nowadays, anyone can be
a stakeholder to the company. I believe that in practice a company will never be able to represent all
of its stakeholders. Nonetheless, with the aim of fulfilling its coordinating role, it should carefully
consider who its stakeholders are.
Lastly, it is important to take into account the consequences of not having diversity within the board,
and the poor decisions and failure that low diversity may cause. Although research shows both
negative and positive results of diversity within a team on team performance, they are still preferred
over non-diverse teams. After all, diversity is a safeguard that prevents bad and poor quality decision-
making (Sunstein & Hastie, 2015). As nowadays those decisions affect many stakeholders, the latter
should not be forgotten.
2.2.5 Diversity as variety within the board
This section of the dissertation will focus on diversity as variety, as defined by Harrison & Klein (2007,
p.1203): “Composition of differences in kind, source, or category relevant knowledge or experience
among unit members; unique or distinctive information”. The authors claim variety to be at its
maximum when it reaches a uniform distribution with an even spread across all the possible categories.
Translated to functional and educational background this means that all possible functional and
educational backgrounds must be represented equally, exhaustive and disjoint.
This might be supported by Sunstein & Hastie (2015) who make an interesting distinction between two
kinds of group members: cognitively central and cognitively peripheral group members. The cognitively
central group members dispose of knowledge that many other group members dispose of as well. The
authors claim that this sort of information is more likely to be shared due to the disproportionate
influence cognitively central group members have in a discussion, though the uniquely held
information (as referred to as variety by Harrison & Klein) that cognitively peripheral group members
dispose of might also be very important. I believe that if we read between the lines we may conclude
that Sunstein & Hastie might also be in favour of equally represented, exhaustive and disjoint
![Page 34: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/34.jpg)
21
functional and educational backgrounds as there might be less shared knowledge and there is more
chance for unique or distinctive information to be brought up in discussions.
Let us now apply these findings to the board of directors. The executive directors would presumably
have rather similar knowledge concerning the day-to-day activities of the companies. If we look at the
independent and other non-executive directors this would mean that all of the independent directors
and other non-executive directors can contribute their own unique expertise and there is no overlap
between directors’ knowledge and experience. In reality their expertise, due to common functional
and educational backgrounds, will never be represented equally, exhaustive and disjoint, but it does
mean that the board must strive to select independent and non-executive members with different
functional and educational backgrounds if it wants to be able to use a diverse mix of expertise and thus
contribute to the quality of decisions made. It also suggests, in practice, not to have too many executive
directors on the board as they presumably have similar backgrounds and would not be contributing to
unique information and could possibly from an opposing team.
Previous studies of diversity within the board mostly focused on variables such as age, gender,
executive or non-executive and independent or not independent. Again, in general I claim such
variables to be more responsible for diversity as separation than variables such as functional and
educational background. Separation is maximized as unit members are split equally at opposing ends
(Harrison & Klein, 2007; Harrison & Sin, 2006), and I believe this will occur more easily through
dichotomous variables such as gender, (non-) executive director or (non-) independent director. Of
course the distinction of executive and (independent) non-executive directors remains crucial to the
board to be able to perform its monitoring role, according to the agency theory, and positive results
cannot be ignored. This dissertation only wants to point to the possible increase of diversity as
separation and its negative consequences.
I believe that functional and educational background will have a bigger impact on diversity as variety
within the board, and when maximized, lead to higher quality decision-making. Variables such as
functional background and educational background have several categories and make it less likely for
directors to fall into only two teams in the board of directors (Harrison & Klein, 2007), which lowers
diversity as separation and reduces the negative components of diversity regarding performance of
the board. If the board would consist of mainly two large groups of board members divided over only
two functional backgrounds, than opposing teams could of course be created. Variety within the board
will reach a maximum when every category of functional background and educational background is
equally spread and represented in the board (Harrison & Klein, 2007). On top of that, the more
![Page 35: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/35.jpg)
22
functional or educational backgrounds are represented within the board, the more they represent
their stakeholders. As Patricia Lenkov (2013) said:”A variety of backgrounds can make the company
more adaptable to its ever changing environment and divergent backgrounds mean tackling the same
idea in differing ways.”
2.2.5.1 Educational background and functional background
2.2.5.1.1 Introduction
This part starts with highlighting the importance of diversity as educational and functional background.
The UK Corporate Governance code (2014) states that diversity should not be limited to gender and
race, but also is about differences of approach and experience. This chapter focusses on this
experience. The European Commission also highlights the importance of professional diversity in its
green paper ‘The EU corporate governance framework’ (2011, p.6): “A variety of professional
backgrounds is needed to ensure that the board as a whole understands certain complexities and
impact of the business on stakeholders”, referring to the stakeholder theory. It also states “accurate
assessment of skills and expertise is the single most important factor in selecting new non-executive
board members”. Kosnik (1990) argued that diversity among board member backgrounds can reduce
the chance of narrow-mindedness and stimulate airing different perspectives.
We will discuss some research concerning educational and functional background as these variables
determine partly the diversity of knowledge and skills that the members of the board possess. Very
little research has yet been done on diversity regarded as both educational and functional background,
although some research has been done on those variables separately, mostly on functional
background. Therefore the added value of this dissertation to previous research is its focus on the
functional and educational backgrounds of board members, a topic barely studied before.
2.2.5.1.2 Functional background
Research done on TMT diversity has yielded both positive and negative results. The positive outcomes
of TMT diversity are higher quality decision-making while the negative outcomes are slower decision-
making, personal conflicts and communication breakdowns (Cannella, Park & Lee, 2008). Once again,
I believe the reason that research might have yielded ambiguous results could be due to a wide
definition of the concept, in this case functional diversity. This is why Bunderson & Sutcliffe (2002)
offer a distinction of the concept. They contribute four different forms of functional diversity of which
![Page 36: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/36.jpg)
23
two will be explained in this dissertation: dominant function diversity and intrapersonal functional
diversity.
Using their definition we could describe the dominant function diversity as diversity in the different
functional areas within which directors have spent the greater part of their careers.
Applying the concept of intrapersonal functional diversity to the board members this would be the
extent to which the board members are narrow specialists or broad generalists (wider range of
functions).
In their research dominant function diversity has a negative effect on information sharing and unit
performance, while intrapersonal functional diversity has a positive effect on these factors (Bunderson
& Sutcliffe, 2002, p.875). Canella, Park & Lee (2008) build on this distinction of functional diversity and
add an internal element: colocation of the TMT members (proportion of members who work at the
same location. Introducing this variable the results changed slightly: TMT intrapersonal functional
diversity still has a positive influence on team functioning, but now also dominant functional diversity
can have a positive influence on firm performance if the TMT is collocated (Cannella, Park & Lee, 2008).
Although research has yielded ambiguous results, this might be an interesting distinction to build on.
In contrary to what Harrison & Klein (2007) claim, Cannella, Park & Lee (2008, p.780) suggest
“executives of broad functional experience have the specialized knowledge needed to effectively make
decisions and the skills, networks, and referent power needed to interact effectively on a TMT”, this
means overlapping variety. Note that these executive directors often become non-executive directors.
Gibson & Vermeulen (2003) join Harrison & Klein (2007) on their definition of maximum variety as they
claim that when a team’s demographic heterogeneity is extremely high the group becomes very open
minded and shares all the unique information. When a group is only moderate heterogenic the group
stops serving as one cohort, opinions won’t converge and potential benefits from heterogeneity won’t
be realized. I believe this goes hand in hand with what Canella, Park & Lee found: dominant function
diversity was found to have a positive influence on firm performance when the TMT is collocated,
which I believe made them serve as one cohort. O’Reilly & Williams (1996) found similar results: when
group members are more familiar with one another they are more able to use unique information.
When translating these results to the board, the question arises whether the board serves as a cohort.
Firstly the board is not collocated. Secondly the board only meets occasionally and has limited time
through which it more difficult to be familiar with other board members and serve as one cohort. Also,
the board definitely does not perform well in terms of demographic heterogeneity: most board
![Page 37: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/37.jpg)
24
members are of certain age, many are national, a majority are men, etc. It is clear that possessing
expertise and knowledge is one thing, sharing knowledge is another. Research clearly yields ambiguous
results. There is only one thing all of the previous research in this chapter agrees on: in some way,
diversity adds more information and ways of thinking which can lead to better decision-making.
Regardless of whether variety in backgrounds has a positive or negative impact on board performance,
the diversity variable functional background can be relevant to the board in performing its service and
coordinating role. For example, a board member with a financial background will probably have many
connections in the financing industry. Another example is that if many of the board members of a
company have public backgrounds, the government might be an important stakeholder to the
company or the industry the company operates in.
2.2.5.1.3 Educational Background
Regarding the board, to the best of my knowledge, little research has yet been done on educational
background of the board members. It must be said that board members are of a certain age and
therefore might have a lot more functional background. Therefore I believe that functional background
might be more relevant in some cases. However, educational background might be interesting
regarding the board of director’s network, and educational background is intended to be a starting
point for the functional background. I believe the educational background of a director can mainly
enhance the execution of the service role: finding resources, and attributing knowledge to the board.
2.2.6 Gender diversity
The kind of diversity most referred to within corporate governance literature is gender diversity.
Several measures were taken to increase women representation in boards: some countries have
introduced quota and some have used push initiatives that were driven by social justice motives (Ali,
Ng & Kulik, 2013). Facts and figures of gender diversity increasing, exist already. In October 2013 the
European Commission (2014) found that the European average of women on the boards was 17.8%.
Egon Zehnder (2014)9 found that from 2012 to 2014 the percentage of women directors on the boards
increased from 15.6% to 20.3%. On the other hand Egon Zehnder (2014) also found that regarding the
board chair positions, only 3% were held by women. Although gender diversity is increasing, studies
9 Egon Zehnder’s European Board Diversity Analysis (2014) profiles the boards of more than 350 of the largest companies across 17 European countries.
![Page 38: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/38.jpg)
25
have yielded ambiguous results. Both positive and negative associations have been found between
gender diversity and various performance measures (Ali, Ng & Kulik, 2013).
2.2.7 National or non-national
In their European board diversity analysis Egon Zehnder (2014) found that in recent years the European
boards became especially more diverse in gender diversity, but also in nationality diversity. A director
is considered to be national, if he is a national to the same country where the company has its
headquarters. As stated before, the diversity variable (non-)national might especially be interesting
concerning the company’s service role. An international board member is probable to have a large
external network of unexplored resources available. Egon Zehnder (2014) shows that 32.3% of board
directors are non-nationals.
![Page 39: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/39.jpg)

3 Methodology
3.1 Sample
This dissertation scrutinizes the board of directors of the top listed companies of Belgium, France,
Spain and the UK. The sample consists all listed companies that were constituents of the associated
stock indexes (BEL 20, CAC 40, IBEX 35 and FTSE 100 respectively) in December 2014 before the last
changes to these indexes were made for 2014. All directors that were a member of one or several of
these boards at December 31th 2014 were included. The reason why these indexes were chosen is
because of the simple fact that each of these indexes mainly consists of companies governed by a
unitary board, and thus the results can easily be compared between countries, with no distinction to
be made between unitary and dual boards. Also, these stock indexes are capitalisation-weighted
indexes and contain companies with the highest capitalisation, and thus represent a lot of the market
capitalisation. The IBEX 35 contains the 35 most liquid Spanish stocks traded in the Madrid Stock
Exchange General Index, but is also capitalisation-weighted.
All companies that were part of the financial and insurance service industry were included, except for
the banks. The EBA (European Banking Authority) guidelines (2012) apply to all board members of
credit institutions, regardless of their board system, and state that board members should be suitable,
meaning they should have the right qualities and theoretical experience. The board member’s
theoretical experience should be assessed, and is supposed to consist of qualifications related to the
areas of economics, law, administration and financial regulation and quantitative methods. Therefore
the theoretical and functional experience (diversity) of board members of banks is to be determined
by these guidelines and are excluded from the sample. The reader should note that for all the following
calculations and results, all banks are excluded and are not included in the sample. Lastly two
companies were excluded because their headquarters is located outside of Europe. All the previous
taken into account, the total sample consists of 164 companies or 1982 directors. A list of included and
excluded companies, with reason of exclusion, can be found in appendix 3.1.
Actually, other samples are used for the empirical study. When drawing conclusions for Europe, all of
the above companies and board members of the above specified total sample are included. When
drawing conclusions for individual countries (Belgium, France, Spain and the United Kingdom), all
companies who have their headquarters in those countries are included. In the empirical study it will
be clearly specified which sample is used based on the words ‘Europe’, ‘Belgium’, ‘France’, ‘Spain’, and
the ‘UK’. Other samples are all companies operating in a specific industry, etc.
![Page 40: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/40.jpg)
27
3.2 Data Collection
3.2.1 Company
Several data was collected for the companies regarding several variables. A first variable is the stock
index (or indexes) the company is listed on. Another variable is the company’s headquarters. This
variable is crucial to determine which companies are included in the sample (to draw conclusion on
country-level), as well as to determine whether a director is national or non-national. This information
was easily found on the Internet. Apart from the company’s headquarters, the sector or main
economic activity (determined by largest operational revenue) of the company was collected,
represented by its NACE code. The NACE code applies to all European Union members, but we looked
for the NACE code for all the companies included in the sample. In most cases the NACE code was
clear, in other cases the primary NACE code was that of holding companies (6420) or head activities
(7010)10. In the latter cases, secondary NACE codes were looked for and chosen. The NACE codes were
collected using the Amadeus database and annual reports for 2014, as well as the company’s website.
The NACE code that was chosen is that of the economic activity that adds most value to the company,
as described by the European Commission (2008) in the NACE Rev. 2.
3.2.2 Board director
Regarding the board members of these companies, the following information was gathered: gender,
(non-) executive, (non-) independent, chairman (or not), employee representative (or not), employee
shareholder representative (or not), age, (non-) national, educational background, and functional
background. All this information was obtained using a company’s annual report for 2014 (Belgium and
the UK), registration document for 2014 (France) and annual corporate governance document for 2014
(Spain). On top of that, several Internet sources were consulted: Wikipedia, Bloomberg, company’s
website etc., to enhance the quality of the information. No data was obtained using e-mails or
interviews, as the sample simply was too large to obtain this information for each individual director.
10 A list of NACE codes can be found on http://ec.europa.eu/competition/mergers/cases/index/nace_all.html
![Page 41: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/41.jpg)
28
3.3 Data classification
Next the companies were classified according to their main economic activity, represented by their
primary NACE code, henceforth referred to as industry. The board members were classified two times:
firstly, according to their functional background, and secondly according to their educational
background. As data would be comparable, and with the intention of calculating a diversity index
(Blau’s index, more on this further in the dissertation), one dominant educational or functional
background category was chosen for each board member, and they were all assigned to one category
only. To avoid subjectivity of classifying the data, the investigator triangulation method was used. In
case of difficulties, another researcher was asked to classify the data. If both researchers allocated the
subject into to same category it was assigned to this category. If both researchers gave a different
answer it was assigned to the category ‘broad educational background’ or ‘broad functional experience
or indecisive’ as it could be allocated to different categories.
3.3.1 Industry classification
The companies were classified according to their main economic activity, or primary NACE code. In this
dissertation, this code represents the industry the company operates in. With the goal of being able to
draw conclusions from analysing the data, several adjustments were made to this classification.
Firstly, the manufacturing category (‘C’) was split in two subcategories: low-tech manufacturing and
high-tech manufacturing. The low-tech manufacturing category is represented by a combination of the
medium-low technology companies and low technology companies, based on NACE Rev. 2 (codes
10:18, 19, 22:25, 31:33). Secondly the high-tech manufacturing category is a combination of the high-
technology and medium-high technology categories (codes 20:21, 26:30) (European Commission, s.d.).
Secondly, the real estate (‘L’) and construction (‘F’) industries were joined in one category: real estate
and construction. Many companies were operating in both sectors and this unified category enhances
the interpretation of results.
Thirdly, categories ‘D’ (Electricity, gas, steam and air conditioning supply) and ‘E’ (Water supply;
sewerage; waste management and remediation activities) are joined in one category: electricity, gas,
steam, and water supply. Both categories are part of utilities and are highly regulated industries. The
categories were joined because the water supply industry only consisted of two companies.

Lastly, some categories weren’t included as there weren’t any companies that had this economic
activity as their main activity. This led to categories, given in table 1:
Table 1: Industry classification categories
Mining and quarrying Accommodation and food service activities
Manufacturing high tech Information and communication
Manufacturing low tech Financial and insurance activities
Electricity, gas, steam, and water supply Professional, scientific and technical activities
Construction and real estate Administrative and support service activities
Wholesale and retail trade Public administration and defence
Transporting and storage
3.3.2 Functional background classification
The functional background variable defined in this dissertation is, in fact, a combination of a director’s
professional experience and track record. Therefore the classification categories include both
professional functions as industry experience. I believe the combination of both (function and
experience) in one variable contributes to the ability to choose a dominant ‘functional background’.
For example, if a director held several CFO functions throughout his/her career in several industries,
the category ‘finance’ was chosen. If, however, a director held several different functions, always in
the energy industry, he/she was allocated to the category ‘energy’. The categories were defined
looking at the data and were chosen trying to achieve maximal workability for analysing. This lead to
the categories given in table 2:
Table 2: Functional background or track record classification categories
Broad or indecisive professional background Marketing, sales & communication
Energy Medicine
Finance Public services
Human resources Real estate
Industrial & technology Retail
IT Telecommunications
Juridical & legal Other

30
The category ‘broad or indecisive professional background’ was chosen when the investigator
triangulation led to different outcomes, because the director had multiple and equally important
functional backgrounds. This category represents the ‘broad generalist’ in intrapersonal functional
diversity as described by Bunderson & Sutcliffe (2002). If a director was allocated to another category,
he is assumed to be a narrow specialist. Employee representatives and employee shareholder
representatives, sitting on the board of CAC 40 companies, were assigned to the category ‘other’, as
their backgrounds actually represent knowledge and experience on a lower level. In very few of these
cases, these representatives held executive positions, and were then assigned the same way as the
other directors. The category ‘other’ contains backgrounds that had little occurrences. In appendix 3.2,
a list of examples for each category is included.
3.3.3 Educational background classification
Last but not least, directors were classified according to their educational background. In most cases,
this was straightforward. In a minority of cases however it wasn’t as clear and several rules were
established and thus need to be taken into consideration. Firstly, many directors obtained several
degrees. More importance was given to the bachelor and initial education, and in case of doubt or
many degrees in different fields the category ‘broad education’ was chosen for the director. This
category represents, similar to the distinction made for intrapersonal functional diversity by
Bunderson & Sutclifffe (2002), a broad generalist in intrapersonal educational diversity. All other
categories are specialist categories. Secondly, it important is that an MBA was not considered in the
educational background as most directors obtained this during their career. Because of the high
profiles of the directors of the board, this was not considered as adding up to diversity and therefore
is not included. Thirdly, many directors qualified as a chartered accountant during their careers, and
this was included in their functional background, as it mostly led to a financial profile. The classification
was made looking at the data to obtain maximal workability, and is given in table 3. A list of categories
and elements is given in appendix 3.3.

3.4 Blau’s Index
Concerning the measuring of diversity, the question of ‘How to measure diversity?’ arises. This
dissertation will follow the suggestion of using an index according to its type of diversity (Harrison &
Klein, 2007; Solanas, Selvam, Navarro & Leiva, 2012). The Blau’s Index will only be calculated for the
board members’ functional and educational background, variables both defined as diversity as variety.
Applied to variety, Blau’s Index has been used in previous studies (Solanas, Selvam, Navarro & Leiva,
2012), and will therefore also be used in this study. The Blau’s index (Blau, 1977) is calculated as
follows:
𝐵 = 1 − ∑ 𝑝𝑖2
𝑘
𝑖=1
p = proportion of group members in the ith category
k = number of categories
The higher the value for B is, the higher the dispersion of members over the several categories, with a
maximum value of (k -1)/ k. This value can only be reached if n = mk (m being a positive integer, n being
group size). In this research the upper value is never reached, and thus there is no problem. The lower
bound for B is zero. The values for the Blau’s index cannot be compared between attributes of interest
when they contain a different number of categories, unless normalised (divided by ‘n’, group size)
(Blau, 1977). In the empirical study, the normalised Blau’s index will be used to compare between
groups, and is used as a proxy for how diverse (diversity as variety) a board is.

4 Empirical Research
4.1 Results
4.1.1 Board size
The average board size found in the results is compared to numbers found in the Spencer Stuart Board
Indexes 2014(for Belgium, France, Spain, and the UK), given in table 4 below. Differences result from
the companies that are included in the sample. Also, in this research banks were excluded from the
sample. For most companies we found similar results, whereas for Spain we found a higher board size.
The Spencer Stuart Spain Board Index (2014) includes 92 companies (apart from 34 companies listed
on the IBEX 35), which thus have a larger board size than companies listed on the IBEX 35. Whereas
France has the largest board size, the UK has the smallest board size.

4.1.2 Gender
4.1.2.1 Gender geographically
In our sample, 23.5% directors are women. Table 5 shows that France performs above average, with
30.9% of the board directors being women. This finding is significantly different compared to all other
countries and Europe on a 5% significance level, given in table 6 which shows the p-values for a two-
tailed independent two samples t-test. On the contrary Spain performs worse, with a proportion of
only 17% being female directors, this number is also significantly different from all other proportions
found in table 5 for α = 0.05. Belgium and the UK perform very similarly to the average for Europe. The
p-values show that the proportion of women do not differ significantly for the following combinations
on a significance level of α = 0.05: Belgium and Europe, the UK and Europe, and the UK and Belgium.

* Two-tailed independent two sample t-test between the gender proportions in between countries/Europe
In Belgium, France and the UK all board of directors, included in the sample, contained women. In
Spain, three out of twenty-four (12.5%) companies did not even have one woman on the board. The
Good Governance Code (2015) suggests that by 2020 the companies should have 30% women on the
board. A binomial test shows that indeed Spain’s gender proportion significantly (α = 0.05, p< 0.001)
differs from the 30% objective. It is clear that Spain still has to gap a bridge. Regardless of whether
Spain will meet this criteria by 2020, it is worrying that three companies have not even got one woman
sitting on its board. Belgium and France are close to their objectives, 33% (law of 28th July 2011)11 and
40% (French law January 2011)12 women by 2017 respectively. The objective for the FTSE 100
companies for the UK is 25% by 2015. Binomial tests show that on a 5% significance level only for the
UK the proportion of women found in the results do not differ from the objectives set. This objective
was indeed achieved (Hutchison, 2015). Two-tailed p-values for Belgium, France, and the UK are 0.001,
< 0.001, and 0.105 respectively.

4.1.2.2 Gender across Industries
For Europe, some gender proportion differences were found among different industries, with the
mining and quarrying industry having the largest proportion of men on the boards (80%). The
accommodation and food service activities sector has the lowest proportion of men on the boards
(67.4%), as shown in table 7. The public administration and defence industry had 83.3% men on the
board, but was excluded since it only represents one company with twelve directors. When comparing
the gender proportions for industries to the average gender proportion for Europe, using a two-tailed
independent two sample t-test, no significant differences are found. When performing the same test
between the accommodation and food service activities and mining and quarrying industry, we do find
significant results (p = 0.039 , α = 0.05) and conclude that the gender proportion differs between these
two industries.

4.1.2.3 Gender across educational backgrounds
We can also look at gender across educational backgrounds, given in table 8. All educational
background profiles have a majority of men, but the engineering profile on the board is clearly
dominated by men: 89.3% of engineering profiles are men, this is significantly different from the
European average on a significance level of 5%. The political and social sciences (52.3%), mathematics
& IT (56.0%), and history, languages & philosophy profiles (57.4%) have the highest proportions of
women, and are also significantly different from the European average on a significance level of 5%. P-
values were calculated using a two-tailed two samples t-test, testing whether the proportion found for
gender is significantly different on a 5% significance level than the overall gender average found for
the total sample (76.5 % of man).

4.1.2.4 Gender across functional backgrounds
The proportion of women on the boards according to their functional backgrounds is another way of
scrutinizing them. Table 9 shows that directors with financial, industrial & technology, retail and real
estate backgrounds are often men: in more than 80% cases directors with these backgrounds were
men, which is significantly different than the European average proportion of men found in the total
sample on a 5% significance level. The opposite was found for directors with energy, human resources,
juridical & legal, IT, and marketing, sales & communication backgrounds: they have lower percentages
of women compared the European average. Two-tailed p-values show that the percentages for these
profiles are indeed significantly different on a 5% significance level. Remarkable is that all of the
defined functional background categories are represented by a large majority of men, except for
human resources. Three quarters of directors with a narrow specialist human resources background
are women. The human resources profile is unique in this regard. This finding is significant on a 5%
significance level, and thus human resources profile has a significantly (α = 0.05) different proportion
of women compared to the European average.

4.1.2.5 Gender across (non-) executive, independent or not, and chairmen
Table 10 shows that in Europe 7.1% of executive directors are women, and 27.3% of non-executive
directors are women. Spain does not even have one single executive female director on the board.
Belgium has the highest proportion of executive women on the board (10% of executives were found
to be women). France has the highest proportion of non-executive female directors (33.4%). Women
are thus more likely to be non-executive directors.

Table 11 shows whether differences between these countries are significant or not for executive
directors. As could be expected all proportions obtained are significantly different than Spain’s
proportion of zero percent (α = 0.05). Between other countries and Europe, no results are found
significantly different on the 5% significance level.

When looking at the number of female chairmen, given in table 15, the findings are very clear. From
all 165 chairmen (164 companies were included, one company with two chairmen) only four are
women. Remarkably, two out of these four women chair on Belgian boards, although only seventeen
of the included countries have their headquarters in Belgium. France on the other hand, has not even
a single woman chairing on a CAC 40 company. Women clearly aren’t at all likely to be chairman, and
mostly are independent non-executive directors.

Table 16 shows the whether the proportions given in table 15 differ significantly geographically. As
could be expected when looking at the percentages in table 15, Belgium has significant values when
compared to most countries/Europe (α = 0.05). The results are not significant when comparing to
Spain, probably due to the low number of observations for both countries. None of the other p-values
are significant on a 5% significance level and thus few proportions significantly differ from each other
for α = 0.05.

4.1.3 Age
4.1.3.1 Age geographically
Concerning age, both average (with its standard deviation), upper quartile, lower quartile, and median
were calculated. The latter is included, as it is less affected by outliers. Table 17 shows that the average
Spanish board member is the oldest for the four countries included within the sample. One fourth of
Spanish board members is older than 69, and 10% is even older than 72. Table 17 further also shows
that Belgium and the UK have the youngest directors serving on the boards.

4.1.3.2 Age across gender
When looking at the age of male directors, these do not differ much from the numbers given in table
11. When looking at the age of female directors, we see that the average female European director
(55.7) is younger than her male colleague (59.7) in Europe. Belgian, French, Spanish and UK female
directors are on average 55.2, 55.8, 57.7, and 55.3 respectively, years old. The average age gap
between male and female directors is the largest for France (5.7 years) and Spain (5.1 years), and the
smallest for Belgium (2.6 years) and the UK (2.9 years). The European average age gap between female
and male directors is 4 years.
4.1.3.3 Age across industries
The age of the board members is not only restricted to geographical comparison, but can also be
compared across industries. The mining and quarrying industry, as given in table 18, has the eldest
directors serving on the boards, the same industry that contained the highest proportion of men. Note
that the mining and quarrying industry also had the highest proportion of men sitting on its boards.
The accommodation and food service, and administrative and support service industries have the
youngest board members. Table 19 shows whether there are significant age differences for some
combinations of industries. The mining and quarrying industry has a significant (α =0.05) age difference
compared to the accommodation and food service industry, financial and insurance industry, public
administration and defence and electricity, gas, steam and water supply industry. The independent
two samples t-test requires checking if variances are equal, this was done using the Levene’s test, and
in case equal variances could not be assumed the p-value was corrected.

4.1.3.4 Age across educational backgrounds
Table 20 shows the variable age across educational backgrounds for the directors. Directors with broad
educational experience are the oldest, together with directors with political and social sciences
educational backgrounds. Directors with engineering, law, and sciences backgrounds are on average
also older than the average European director. The opposite was found for directors with studies in
economics and mathematics & IT. Table 21 below again shows whether differences are significant on
a 5% significance level, and provides the Levene’s test and p-values. When the Levene’s test is
significant, equal variances are not assumed and the p-value must be corrected, however, the test was

samples t-tests between several functional backgrounds to prove that there are indeed significant age
differences between industries. The test was not run for every single combination (a total of 91
combinations), but is given between several high and low values to look if these age gaps are indeed
significant. Age differences were found between public services and human resources, public services

4.1.3.6 Age across (non-) executive, independent or not, and chairmen
When looking at the variable age across executive directors and we compare the age of non-executive
directors, table 24 shows that executive directors have a significantly different average age for Europe,
France, and the UK than their non-executive colleagues. Before performing an independent two
samples t-test, the Levene’s test was again performed to check if the assumption of equal variances
holds, if this wasn’t the case the Levene’s correction was applied. Only for Belgium no significant
difference is found between the age of executive and non-executive directors. Interestingly we find a
very large age difference for the UK.

Table 25 performs the same test as table 24 but for the dependent variable age and factor variable
(non-) independent. Results are similar as for table 24. Independent directors are significantly (α =0.05)
of different age than their colleagues for Europe, France, Spain, and the UK (α =0.05). Only for Belgium
no age difference was found between independent and non-independent directors.

We can also check whether there is an age difference between chairmen and other directors, this is
displayed in table 26. The findings are interesting: no significant difference (α = 0.05) was found for
Belgium, France and Spain two-sided. The most extreme results are found for the UK. The average
chairmen in the UK is 64.8 years old, while the average director who is not chairing the board is 56.8
years old. Chairmen in the UK are significantly (α = 5%) off different age than their colleagues. Similar
results hold for Europe.

4.1.4 Nationality
4.1.4.1 Nationality geographically
Table 27 shows the proportion of non-national directors serving on the boards of Belgium, France,
Spain, and the UK. The findings clearly illustrate that Belgium and the UK have the highest proportion
of non-nationals serving on their boards. On the contrary, Spain has the lowest proportion of non-
nationals serving its boards. It must be noted that for approximately one third of Spain’s board
members, no nationality was found. The European average is 67.2 % of nationals and thus 32.8%
international board directors.

Table 28 shows the p-values for a two-sided independent two samples t-test between countries and
Europe. Between Belgium and Europe, the UK and Europe and Belgium and the UK no significant
differences were found on a significance level α = 0.05. They all have a similar proportion of
international directors on the board. France and Spain have a significantly (α =0.05) different
proportion of non-national directors on its boards compared to its European average. Differences are
also found on a 5 % significance level between Spain and Belgium, France and Belgium, France and
Spain, the UK and France and lastly Spain and the UK.

Two-sided independent two sample t-test between nationality proportions of a countries and Europe compared to each other.
4.1.4.2 Nationality across industries
Another way of comparing the proportion of non-national directors, is across industries, given in table
29. We find interesting results for the mining and quarrying, and the administrative and support
activities industry: as opposed to the other industries included in the sample, these industries contain
a majority of non-national directors. These finding significantly differ from the European average (α=
0.05). The manufacturing industry also has a large number of non-national directors. These results
suggest that the companies that are part of all the above mentioned industries operate in more
international environments, and therefore are more dependent on establishing links with the
company’s external international environment (service role). Table 29 shows that most non-national
proportions significantly differ from the European found average on a 5% significance level. The
construction and real estate and electricity, gas, steam and water supply industry have extremely high
proportions of national directors. These findings significantly differ from the European average for α =
0.05. Now let us compare some of the ‘extreme’ industries to ‘moderate’ industries. When comparing
industry percentages among each other, using a two-sided independent two samples t-test, the mining
and quarrying industry even has a significantly different proportion of non-nationals compared to the
![Page 60: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/60.jpg)
47
high-tech manufacturing industry (p < 0.001, α = 0.05). The construction and real estate industry and
electricity, gas, steam and water supply industry both have significantly different proportions of non-
nationals when compared to the high-tech manufacturing industry. Note that the high-tech
manufacturing industry was used as moderate industry in the calculations. It is clear that the
proportion of non-nationals varies strongly among industries.

4.1.4.3 Nationality across educational background
Table 30 shows the diversity variable (non-) nationals across educational backgrounds. A two-tailed
independent sample t-test is performed between the proportion of non-nationals of the educational
background categories and the European average (32.8%). Directors with a medical background have
the highest proportion of non-nationals. This finding is significant on a significance level of α =0.05,
and thus the findings are different from the European average. Economics and political and social
sciences also have a higher than average proportion of international directors, this finding is also
significant on a 5% significance level. The lowest proportion of non-national directors is found for
directors with an educational background of mathematics & IT, although this finding is not significant
(α = 0.05).

Table 31 shows the results for the cross-tabulation between diversity variables nationality and

Medical functional background has, as medical educational background, the highest proportion of non-
national directors, this finding is significantly different on a 5% significance level. IT,
telecommunications, and industrial & technology backgrounds also contain high; significantly (α =
0.05) different proportions of non-nationals compared to the European average. Another interesting
finding is the real estate profile, which consists of 95% national directors, significant for α = 0.05.
Financial and public service profiles are mostly national profiles (28.5% and 23.1% non-national
directors respectively), these numbers are also significantly different than the European average.

geographically
Table 32 shows the proportions of executive, non-executive and independent directors that are also
non-national directors. We find the highest proportions of non-nationals for executive and
independent directors for Belgium. The UK has the highest proportion of non-nationals among non-
executives compared to Europe and other countries. France and Spain show very low percentages of
non-national directors among executive directors. French boards didn’t contain chairwomen and thus
also no non-national chairwomen. Spain has the lowest proportion of non-national directors across all

(significance level = 0.05). Also for both Belgium and the UK no differences are significant with Europe
and themselves (between Belgium and the UK) on a significance level of α = 0.05.

Results are similar for the nationality proportion among non-executive directors when performing the
independent two samples t-test between countries and Europe, as shown in table 34. Again there is
no significant (α = 0.05) difference between Belgium and Europe or the UK and Europe, neither is there
a significant (α = 0.05) difference between Belgium and the UK. For Belgium there is no significant
difference with France on a significance level of 5%, but there is again a significant difference with
Spain. Spain has a significant different proportion of non-nationals compared to any other country or
Europe on a 5% significance level. France also has a significantly different proportion on a significance
level of 5% compared to Europe, Spain and the UK.

Lastly, table 36 below shows that, performing an independent two-samples t-test for nationality
proportion across chairmen geographically, results are not significantly (α = 0.05) different between
France and Spain. Neither are the results significantly different between Europe, Belgium, and the UK
on the other hand on a significance level of α = 0.05. France and Spain’s proportion of non-national
chairmen is different than for Europe, Belgium, and the UK (α = 0.05).

Two-sided independent two sample t-test between nationality proportions among chairmen a countries and Europe compared to each other.
The average European country has, based on the sample, a proportion of 32.8% of non-national
directors (203 missing values out of a total of 1982 values, 10.2%, were not included). Of the executive
board members, 22.7% were non-nationals, and 35.1% of non-executive directors were non-nationals
(again for both, missing values were not included). These results show that non-executive directors
play a more important international role, and support the resource dependency theory and service
role, as the service role concerns establishing contacts with the external, her international, and
environment. This is even validated more when looking at the proportion of independent non-national
directors, which is 39.1% (chairmen excluded).
4.1.5 Executive or non-executive
4.1.5.1 (Non-) executive geographically
When looking at the diversity variable executive or non-executive, table 37 shows that Belgium has
the highest proportion of non-executives, closely followed by France. The UK is the worst performer
of the four countries included in the sample, with a proportion of 72.9% of non-executives. The average
proportion of non-executives found for Europe is 80.9%.

Two-sided independent two sample t-test between (non-) executive proportions among countries and Europe compared to each other.
All countries (no objective was found for France) comply with the quota set by their governance codes.
The 2009 Code (Belgium) and the UK corporate governance code both state that at least half of the
board should consist of non-executive directors. When comparing the results found with a norm
(binomial test) of 50%, testing one-sided on α = 0.05, we can conclude that we can reject the null
hypothesis for Belgium and the UK that the proportions are lower than the norm, with p-values both
smaller than 0.001. For Spain also 84.3% fulfils the objective of ‘a large majority’ of non-executive
directors set by the Good Governance Code (2015). When performing a similar test for Spain, using
75% non-executives as ‘large majority’, a one-sided test with this norm results in significant results (p
< 0.001 , α = 0.05) and thus Spain complies with its soft objective.

4.1.5.2 (Non-) executive across industries
When looking at the number of executive and non-executive directors across industries, given in table
39, the industrial sectors (manufacturing, mining and quarrying, and construction and real estate) have
the lowest proportion of executive directors (results are only significantly different from the European
average for the high-tech manufacturing industry, for α = 0.05). The transport and storage industry,
and electricity, gas, steam and water supply industry also have a low proportion of executive directors.
The highest proportions are found for the accommodation and food service activities industry,
administrative and support activities industry, and financial and insurance activities industry. All
industries have large majorities of non-executive directors. Results are only significantly different from
the European average for the financial services industry (α = 0.05).

4.1.6.1 Independent or not independent geographically
To calculate statistics concerning independent directors on the board, chairmen were excluded, as
suggested by the UK corporate governance code. This was applied for all companies of all countries in
favour of the comparability of data. Table 40 shows that for Europe, approximately 60% of non-
executive directors are also independent. Belgium and France are close to this average with 57.8% and
58.4% respectively. The 2009 Code for Belgium states the board should contain at least three

objectives set by the AFEP/MEDEF (50%). 58.4% is significantly different on a 5% significance level using
a binomial test (p = 0.001). The UK has a larger proportion of independent directors (66.4%) and
complies with the proportion of independent non-executives set by the UK corporate governance code
(>=50%). This 66.4% is significantly different from 50% (p < 0.001, α = 0.05). Spain has a lower
proportion of independent directors (46.9%), and on average does comply with the 50% proportion
set by the Good Governance Code (2015): 46.9% is not significantly different from 50% (p = 0.144, α =

Table 41 shows that for Spain the proportion of independent directors is significantly different
compared to Europe, Belgium, France, and the UK (one-sided thus p-values from table 34 are divided
by two for Spain, α = 0.05). For the UK the proportion of independent directors is also significantly
different compared to Europe, Belgium, France, and Spain (again α = 0.05). For Belgium the results are
significantly different compared to Spain and the UK on a 5% significance level.

4.1.6.2 Independent or not independent across industries
When looking at the number of independent directors across industries, given in table 42, the mining
and quarrying industry stands out with a proportion of 73.6% independent directors. This proportion
is significantly differs from the European average (59.7%) on a 5% significance level. This very high
proportion can be partly explained because all but one of the companies that were categorised in the
mining and quarrying industry have their headquarters in the UK, which has the highest proportion of
independent directors. The construction and real estate industry has the lowest proportion of
independent directors of all industries in the sample, and this finding significantly differs from the
European average (α = 0.05). More specifically, Spain has a proportion of 33.7% of independent
directors in the construction and real estate industry (of a total of 83 members). However, this 33.7%
does not differ significantly from the 41.6% found for the construction and real estate industry for
Europe using a two-tailed independent two sample t-test (α =0.05, p = 0.109).

4.1.7 Educational Background
When looking at the directors’ educational backgrounds, table 43 clearly shows that the majority of
directors have an economical background (36.0%, this also includes finance). The second and third
most common educational background are engineering and law, with 19.7% and 12.5% respectively.
Broad generalists account for 12.4% of the total sample. When comparing the educational
backgrounds among diversity variable (non-) executive and independent results are similar among
these director classifications. Executive directors are less educated broadly (5.3%) compared to non-
executive (11.3%) and independent (12.7% directors. The results are significant on a significance level
of 5% for a two-tailed independent two sample t-test (p- values are both < 0.001).
When calculating the Blau’s index for the educational background for Europe (‘All’ in table 43), we
treat ‘broad education and ‘other’ also as one category and obtain a value of 0.7926, or standardized
(divided by n) 0.079.

4.1.8 Functional Background
When looking at the board directors’ functional backgrounds or track records, the results are,
surprisingly, similar between all directors, non-executive directors and independent directors. The
result are given for all sort of directors in table 44. Approximately 40% of all directors have a financial
background. It must be argued that 12% of all companies in the sample are operating in the financial
services industry, but this 40% average on total number of directors is a lot higher. There is no doubt
that financial expertise is considered to be very important on the board. Listed companies must report
to the public on their financials, and the audit committee must oversee financial reporting and
disclosure. When comparing the proportion of financial profiles between executive (38.5%) and non-
executive directors (43.9%) we find that these numbers are significantly different (two-sided, p = 0.027,
α = 0.05).
The second most common profile (12.7%) is the ‘industrial & technology’ profile. Many directors
possess industrial, technological or scientific knowledge.
Joint third most common categories are marketing, sales & communication and public services. Both
categories play an important role in the service role: attracting resources, reaching people, establishing
links to obtain information, etc. 5.1% of all directors are/were active in the public services sector
(politicians, ambassadors, etc.).
Two categories that are the least common, though not included in the category ‘other’, are human
resources and medicine. The human resources and medicine functions fulfil the service role. Once
again, the categories were chosen after looking at the data, to enhance quality of this research. For
example, medicine was defined separately as most of the directors who were allocated to this
category, were a board member of companies operating in the pharmaceutical industry (defined as
high-tech manufacturing) ,and these directors more specifically had backgrounds in the field of
oncology. The human resource profile is less common, this was also found for Belgium by GUBERNA &
VBO (s.d.) in their two-yearly monitoring research. The Blau’s index was also calculated for functional
background and is 0.79, and 0.056 after normalising for the number of categories.
![Page 72: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/72.jpg)

Table 44: Diversity variable functional background
Table with numbers concerning the diversity variable functional background, calculated using SPSS * Excluding missing numbers ** Not excluding missing numbers, these are the missing numbers
Next we will zoom in on several functional backgrounds for several industries and explain the findings
given in table 45. The number of directors mentioned for the industry, is the number of directors
included in the calculations for the Blau’s index (missing values excluded).
The accommodation and food service industry (AF) includes 46 directors who mostly have (43.5%
financial backgrounds and marketing, sales & communication (19.6%) backgrounds. Its normalised
Blau’s index is 0.052. The board’s service role is thus very important to this industry.
The administrative and support service activities industry (AS) includes 34 directors. The most common
functional background is finance (50%), followed by IT (11.8%) and industrial & technology (8.8%). This
percentage for finance is high compared to other industries. It also contains a lot of directors with a
broad track record (19.6%). Its normalised Blau’s index is 0.050.
The construction and real estate industry (CRE) includes 176 directors, who again mostly have financial
profiles (35.2%), but this is not as high as compared to the European average or other industries.

Second most common backgrounds, which can be expected, are industrial & technology (which
contains construction) and real estate. Its normalised index is 0.058.
Next is the electricity, gas, steam, and water supply industry (EGSW), which contains 177 directors.
Only 28.2% are financial profiles, which is rather low when compared to the other industries. Second
most common are energy and public services backgrounds, followed by industrial & technology, and
juridical backgrounds. This clearly reflects the high regulation of the energy and utilities industry. Links
with the government, lawyers and industry experts are important. The government is thus an
important stakeholder/ resource to these companies. Its normalised Blau’s index is 0.059.
The financial and insurance industry (FI) contains 234 directors, of whom 78.2% has a financial
background. This high percentage can be explained because it contains financial profiles for both
accounting/auditing financial expertise, as well as broad finance industry experience (investment,
banking, etc.). This high percentage is significantly different than the average (40.70%) on a 5%
significance level, using a two-tailed two samples t-test (p <0.001). As can be expected, IT and juridical
backgrounds are second and third most common backgrounds. Its normalised Blau’s index is 0.027,
clearly lower than for other industries.
For the information and communication industry (IC) 180 directors were included. Financial profiles
are again most common (38.3%), followed by IT (9.4%), marketing, sales & communications (8.9%),
and telecommunications (7.8%) as can be expected. Rather high values were also found for juridical
and public services profiles (5.6% and 5% respectively) which could point to regulation in this industry
as well, and thus the government may also be an important stakeholder/ resource to this industry.
Also taking into account the important stake for marketing, sales & communication, it is clear that the
service role is of great importance to the information and communication industry. Its normalised
Blau’s index is 0.057.
For the high-tech manufacturing industry (HTM), 335 directors are included. The most common profile
‘finance’ (32.2%) is closely followed by the industrial & technology profile (26.6%). Most other
categories are represented equally (1%-5%). Its normalised Blau’s index is 0.057.
Another industry is the low-tech manufacturing industry (LTM), containing 239 directors. This category
is similar in terms of functional background diversity to the high-tech manufacturing industry, as most
categories are represented equally. The difference between both categories can be found in the
proportions of financial and industrial & technology profiles: the low-tech manufacturing industry
![Page 74: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/74.jpg)
61
contains a higher proportion of financial profiles, and a lower proportion of industrial & technology
profiles. As it is ‘low-tech’, it thus contains fewer industrial and technology profiles. Also, it contains a
large proportion of directors with broad functional backgrounds (13.8%). Its normalised Blau’s index is
0.055.
The mining and quarrying industry (MQ) contains 139 directors. Again, most common are financial
profiles (35.3%). Second and third most common are the industrial & technology profiles (28.1%) and
energy profiles (15.1%). This was expected as the mining and quarrying industry is closely related the
oil industry which contains both industrial & technology and energy profiles. Juridical and public
service profiles are represented equally (4.3%) and again point to the importance of the government
as stakeholder or resource. Its normalised Blau’s index is 0.054.
The professional, scientific and technical activities industry (PST) is an aggregate of the following
businesses: business and other management consultancies, technical testing and analysis, advertising
and marketing, and engineering activities and other related technical consultancies. It contained 56
directors, of whom 39.3% are financial profiles. The second most common profile is the public services
profile (12.5%). This industry is unique in this regard and clearly points towards the importance of the
government as stakeholder or resource. The third most common profile is the industrial & technology
profile. Its normalised Blau’s index is 0.056.
The transporting and storage industry (TS) contains 70 directors, of whom the most common profile
is, again, financial (38.6%). Second most common is the retail profile: evidence suggests that the retail
industry is an important stakeholder: this reflects the retail industry as a supplier. Many of the directors
have a broad track record (15.7%) and juridical and marketing, sales & communication profiles are also
common profiles (7.1%). Its normalised Blau’s index is 0.056.
Last but not least, the wholesale and retail trade industry (WR) contains 227 directors of whom the
largest part are financial profiles (33.5%), followed be retail profiles (20.3%). Marketing, sales &
communication profiles aren’t uncommon (8.8%) and again the government also seems an important
stakeholder or resource (8.8% are public service profiles). Its normalised Blau’s index is 0.058.
We didn’t take a closer look to the public administration and defence industry as it only contained one
company.

In terms of functional background diversity, all industries obtain similar values for the normalised
Blau’s index (0.05 -0.06), except for the financial and insurance industry, which scores significantly
lower (0.027).

5 Conclusion
The literature study starts with discussing the importance of corporate governance due to past
malpractices (Enron, Ahold, Parmalat and the financial crisis), followed by the plethora of point views
that exist concerning this broadly discussed topic. The conclusion is that nowadays stakeholders should
at least be included in these definitions and boards should be more diverse. Companies are nowadays
operating in dynamic environments and should therefore represent all of their stakeholders, as they
all matter. Corporate governance should not be driven by compliance, but by engagement. As I believe,
it is nearly impossible for a company to represent all of its stakeholders; a company should carefully
consider who its most important stakeholders are, and represent those stakeholders in the board.
Although the results concerning the impact diversity has on board performance are ambiguous
(positive outcomes are related to higher quality decision-making, negative outcomes are related to
slower decision-making), corporate governance nonetheless acts as a safeguard to prevent
malpractices.
The board, its models and roles are discussed. Concerning board diversity, corporate governance codes
for Belgium, France, Spain and the UK recommend large majorities of non-executive directors or at
least more than half of the board members to be non-executives. These recommendations show that
the unitary board system tries to solve the lack of a dual board system. Also, these recommendations
of large majorities of NEDs support the board’s monitoring role and agency theory: non-executive
directors are expected to be better at monitoring. On the contrary, these recommendations contradict
the stewardship theory, which believes that a majority of executive directors is required: executive
directors do not have conflicts of interest with the owners of the company and have the required
experience. Results show that all countries on average comply with these recommendations and have
majorities of independent non-executive directors. Also, Europe has an average proportion of 80.9%
of non-executive directors. All evidence thus supports the agency theory and the importance of the
board’s monitoring role, while contradicting the stewardship theory.
Harrison & Klein (2007) make an interesting distinction into three sorts of diversity that has proven to
be extremely useful in describing aspects on diversity: diversity as variety, separation and disparity.
The added value of this dissertation can be found mainly in the board members’ functional and
educational backgrounds, both aspects of diversity as variety. The availability of information within the
board is one thing, while sharing information is another thing. As variety becomes more equally and
uniformly spread within the board, unique information becomes more likely to be spread. I believe a
![Page 78: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/78.jpg)
65
more diverse board in terms of diversity as variety, more specifically concerning functional
backgrounds and educational backgrounds, to have two possible impacts on the board’s strategic role:
positive and negative. The upside is higher quality decision-making, while the downside is slower
decision-making. Nonetheless, I strongly believe that these educational and functional backgrounds
reveal what stakeholders are important to the board, and where the company is trying to find its
resources. Functional and educational backgrounds are thus mainly relevant when considering the
stakeholder theory and resource dependency theory, and address the board’s coordinating role and
service role.
This dissertation made a cartography of the mix of profiles within the board of directors within their
environment of top-listed companies within Belgium, France, Spain, and the UK (excluding banks).
Several cross-tabulations show the following results, which could easily be compared across countries
or industries as all of the companies included in the sample have unitary boards.
First of all, all results found in the empirical study for Europe were very similar to the results found in
pre-existing, large-scale studies (conducted by Egon Zehnder, Spencer Stuart) which is evidence for
reproducibility the data. The minority of directors are female (23.5%), as was expected. These female
directors are most likely to be independent non-executive directors. In contrast, women are very
unlikely to hold chairing positions. On average, the European director is 59.9 years old with an age gap
of 5.8 years between executive directors (54.1 years) and non-executive directors (59.9 years).
Similarly, an age gap of 3.1 years was found between independent directors (60.1) and non-
independent directors (57 years). An age gap of 4.8 years was found between chairmen (63.2 years)
and non-chairmen (58.4). Results clearly show that the average age varies with the sort of director. A
proportion of 32.8 % of directors sitting on European boards are non-national directors, and these are
most likely to be independent, followed by non-executive, executive and lastly chairmen. Independent
directors and non-executive directors, important in establishing links (service role) and representing
stakeholders (coordinating role), are thus found more likely to be non-nationals. This evidence
supports that companies nowadays operate in a dynamic and global world and finding resources often
means crossing borders. Findings also stress the importance of independent non-executive directors
on the boards: 59.7% of all directors are deemed independent.
Belgian’s average board size is 12.3. In terms of gender diversity, Belgium performs similarly compared
to Europe. Belgium has the highest proportion of female executives and chairwomen and also has a
high proportion of independent female directors. The average Belgian director is 57.2 years old, no
age differences were found among diversity variables (non-executive versus executive, independent
![Page 79: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/79.jpg)
66
versus non-independent and chairmen versus non-chairmen). In general, Belgium has very high
proportions of non-national directors. Especially high when compared to other countries, are
proportions found for foreign independent directors. We thus conclude that the Belgian board is rather
international and the age of board members does not differ among sorts of directors. The reason that
Belgium boards are international is probably due to the fact that Belgium is a small country and it is
thus relatively easy to cross its borders to find new markets and try to attract resources.
France has an average board size of 14.6, which is largest size found for all four countries. French
boards have the highest proportion of female directors (30.9%), which also reflects that of all four
countries France had the highest set objective. France also has the highest proportions of female
independent non-executive directors and non-executive female directors. Contrary to the previous,
not even one woman was chairing a CAC 40 company (banks were excluded from the sample). The
average board member sitting on a French board is 59.7 years old, although significant age gaps were
found between executive (56.7 years) and non-executive directors (60.1 years) and independent (61.7
years) and non-independent directors (57.5 years). Executive directors and non-independent directors
have lower age averages. Furthermore France has low proportions of non-nationals and high
proportions of non-executives (89.9%) when compared the European average. France thus especially
performs well in terms of gender diversity. The high proportion of NEDs found for France is again
evidence that supports the agency theory. The low proportion of non-national directors compared to
Belgium and the UK can be explained by the fact that French companies, constituents of the CAC 40,
operate in more national environments than Belgian and UK companies, although it must be argued
that all companies included in the sample are global, listed companies operating in international
environments. Possibly, they don’t yet recognize the value of foreign resources and experience as
much as Belgium and the UK do.
The UK has the smallest board size (10.9). The UK performs similarly to the European average
concerning gender diversity and its objective of 25% by 2015 was achieved. Concerning the diversity
variable age, interesting results are found. Though the average age is 59.4 years, very large age gaps
were found. Executives are on average 52.7 years old, and non-executives 59.4 years old. An age gap
was also found between independent (58.8) and non-independent (55.6) directors. The largest age gap
was found between chairmen (64.8) and non-chairmen (56.8): eight years. The UK performs similarly
to Europe concerning proportion of non-national directors, but has the highest proportion of non-
executive non-national directors. Interestingly, although the UK has the lowest proportion of non-
executive directors, it has the highest proportion of independent directors: this clearly reflects the fact
that the UK corporate governance codes only mentions ‘independent non-executive’ directors and
![Page 80: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/80.jpg)
67
doesn’t mention anything specifically on non-executive directors and independent directors
separately. It is clear that the UK values international experience on the boards and that in the UK
independent non-executive directors are valued who are more experienced and possibly have larger
networks, or in other words: who are older. Similarly to Belgium, the UK understands the need to
attract foreign directors to reach new markets.
Spain’s average board size is 13.25. This is different from what the Spencer Stuart Spain Board Index
(2014) found, which included a total of 92 companies, and thus we conclude that the IBEX 35 has a
larger board size than the other (smaller) Spanish companies. Spain performs especially badly
concerning gender diversity: only 17% are women, there are boards without women, no female
executives were found and Spain has the lowest proportion of female independent directors (25.9%).
The average age is 62 years, the largest average found for all four countries. A significant age gap was
only found between executive directors (59.1 years) and non-executive directors (62.5 years). Lastly,
Spain has the lowest proportion of non-national directors. All findings point towards rather old, closed,
national, male board of directors. The Spanish boards especially provide bad numbers for gender
diversity. All findings clearly point towards an old boys’ network preventing women to join the board
and neglecting the importance of foreign directors on the board.
Concerning educational backgrounds, boards are dominated by economic, engineering and law
profiles. These results are consistent with the findings found by GUBERNA & VBO (s.d.) in their two-
yearly monitoring research. Note that the educational background economics, as it is the most
common background, shows the importance of financial reporting and disclosure. Results show a very
large proportion of men for the engineering profile (89.3%). Political and social sciences profiles are
men in 52.3% of cases and therefore contain the highest percentage of women across all educational
backgrounds. Thus, some educational backgrounds are indeed more represented by men than others.
In contrast, all educational backgrounds contain a majority of men and it seems unfeasible that all
professions are more typical of men. Several significant age differences were also found between
educational backgrounds: broad education and economics, broad education and mathematics & IT,
and engineering and economics. Another exceptional finding, compared to other educational
backgrounds, is that medical educational backgrounds are mostly international profiles (71.4%).
When looking at the board members’ functional backgrounds, we see that the most common profile
is without doubt the financial profile (40.7%). This again clearly shows the importance of financial
reporting and disclosure for listed companies and is evidence that supports the board’s monitoring
role. The second most common background is the industrial & technology background. Broad
![Page 81: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/81.jpg)
68
generalists account for 10.8% of all profiles. These broad generalists are more likely to be independent
or non-executive directors than executive directors. As TMT literature believes that team members’
intrapersonal function diversity always has a positive impact on decision-making, and dominant
function diversity only has a positive impact on decision-making when collocated (Cannella, Park &
Lee, 2008), and the board isn’t collocated, these findings clearly suggest that boards should have more
independent or non-executive directors on the board, as they are more likely to have broad
intrapersonal function diversity compared to executive directors and when sitting on the board are
thus more likely to have a positive impact on higher quality decision-making. All functional
backgrounds are dominated by a majority of men, except for the human resources profile. Perhaps the
human resources profile requires a skillset or mind-set, which is very typical of women. The human
resources profile is also the profile with the youngest age. The real estate profile is dominated by 91.3%
men and seems to be more typical of men. Women are second most common to the marketing, sales
& communication functional background, and this category also has lower average age. Several age
gaps were found between functional backgrounds. Directors with a public service background are on
average older than several other functional backgrounds. A possible underlying rationale could be that
older directors have already established larger networks and have more experience, which might be
valued highly in a connection with the government. Consistent with the educational backgrounds, the
medical educational backgrounds contain the highest proportion of non-national directors (72.7%). As
these directors were mostly active in the pharmaceutical industry, the pharmaceutical industry is thus
very international and acknowledges the importance of foreign resources and experience.
Telecommunications and IT are also often international profiles, in 53.3% and 53.2% of cases
respectively.
For the accommodation and food service industry a high proportion of women on the board was found,
compared to other industries. It also has young directors who are mostly national with a financial
background. Furthermore this industry contains the highest proportion of broad generalists (functional
background diversity) across all industries (19.6%). This industry also contains the highest proportion
of marketing, sales & communication profiles (19.6%), which supports the importance of the service
role to this industry.
The administrative and support service activities industry also has young directors, though in this case
mostly international with a financial background (50%) or IT background (11.8%). It seems that
financial knowledge and IT knowledge are valuable information (resources) to this industry, and
international experience and resources are valued highly.

69
The construction and real estate industry mainly values financial profiles, industrial & technology
profiles and real estate profiles. Evidence suggests that the construction and real estate industry is the
most national industry of all industries included in the sample, this is probably due to the nature of the
business: these companies operate in domestic markets.
Also very domestic (88.2% of directors are national) and containing many non-executive directors is
the electricity, gas, steam, and water supply industry. The profile of directors sitting on these boards
clearly reflects the high regulation within this industry is: the highest proportions of legal backgrounds
and public services backgrounds were found, 7.3% and 13.6% respectively. The government is clearly
and important stakeholder to this industry.
The information and communication industry performs similarly to the averages for most variables.
This industry contains many, more or less equally weighted, though important functional backgrounds:
IT, juridical & legal, marketing, sales & communication, retail and telecommunications. This industry
seems confronted with many stakeholders and must obtain information or resources in many different
areas. It is thus not surprising that 12.8% of all backgrounds are broad generalists with broad spectrums
of experience. This industry also seems confronted with regulations and the government as
stakeholder.
Both high-tech- and low-tech manufacturing industries have high proportions of non-executive
directors and the average age is also higher compared to other industries. Results are similar between
both industries: financial profiles are most common, followed by industrial & technology profiles,
although the high-tech manufacturing has a larger proportion of industrial & technology profiles, while
part of these profiles are converted to financial profiles when looking at the low-tech manufacturing
industry.
Interesting results were found for the mining and quarrying industry. It has the highest proportion of
male directors, the highest average age of directors, and a majority of non-national directors. High
proportions of non-executive directors were found for all industrial industries. Furthermore the mining
and quarrying industry also has the highest proportion of independent directors, and evidence
suggests that the government is an important stakeholder. Directors sitting on board of companies in
the mining and quarrying industry mostly have financial and industrial profiles. This industry seems to
operate in an international environment and seems by nature more specific of men.
![Page 83: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/83.jpg)
70
When looking at the professional, scientific, and technical activities industry, an in industry with a large
proportion of independent directors, evidence shows an interesting finding: an above average
proportion of public services profiles. Links with the government, or the government as a stakeholder
seem very important to this industry. Surprisingly this industry has a large proportion of energy profiles
(16.1%). This industry probably offers several consultancy, scientific or technical activities towards the
energy industry. This could also explain why there is a large proportion of public services profiles, as
this was also found for the electricity, gas, steam and water supply industry. The energy industry might
thus be an important stakeholder to the professional, scientific and technical activities industry.
The transporting and storage industry is again dominated by financial profiles. Furthermore this
industry also contains an above average proportion of broad generalist profiles. The transporting and
storage industry has a large proportion of non-executives compared to other industries. Evidence
suggests that the retail industry is an important stakeholder. This can be explained because the
transporting and storage industry closely work together with retail companies to transport, store and
deliver the products.
The wholesale and retail industry mainly contains financial and retail profiles. The government also
seems an important stakeholder or resource to the wholesale and retail industry, and marketing
profiles aren’t uncommon, which also doesn’t come as a surprise. Marketing experience is important
to the retail industry.
As the public and administration and defence industry only contained one company, no conclusions
are drawn specifically for this industry.
For all industries similar values were found concerning the normalised Blau’s index, except for the
financial and insurance industry. This industry, not surprisingly, has a very low value for the Blau’s
index. The financial and insurance industry has a high proportion of men serving on the board, and
contains a large majority of financial backgrounds. When linking this to the financial crisis one might
suggest the failure of this industry is, possibly, reflected in its value for the Blau’s index. Compared to
other industries, which all have values above 0.05 for the normalised Blau’s index, a value of 0.027 for
the financial and insurance industry stands out enormously. As diversity plays an important role as a
safeguard to prevent poor quality decision-making (Sunstein & Hastie, 2015), it becomes clear that this
safeguard simply is not there in terms of functional background diversity in the financial services
industry.
![Page 84: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/84.jpg)
71
This dissertation shows that taking into account functional and educational background clearly adds
value, especially towards understanding the company’s service role and coordinating role. Including
these two variables definitely gives an idea of the several stakeholders who are connected to these
companies or industries.
![Page 85: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/85.jpg)

5.1 Limitations
Although this dissertation provides some interesting outcomes and the empirical study certainly has
the advantage of a large sample, it also has several limitations. Firstly, banks were excluded. This is a
strength, but also a weakness. A strength because regulations already strongly determine the mix of
profiles on the boards of banks, a weakness because it wasn’t checked and the sample is actually biased
when drawing conclusions for ‘Europe’. Secondly, the sample only included listed companies. The
sample captures a lot of the market capitalisation, although it does not reflect boards of smaller
companies. Thirdly, when conclusions are drawn for ‘Europe’, we are actually mainly drawing
conclusions for Belgium, France, Spain, and the UK. It must be noted that when outcomes of the
empirical study were compared to results found by other large studies, the outcomes were similar.
Fourthly, no additional data was obtained using interviews because of the size of the sample, which
resulted in several missing values. Fifthly when using the investor triangulation method to increase
objectivity when classifying the data, the opinion of a second researcher was only asked for in case of
doubt. The sample was simply too large for this dissertation to ask another researcher to classify every
single director, and thus no kappa value could be calculated. Sixthly, the outcomes of the research also
depend on the classifications. Companies were classified according to their industries using the NACE
code, a European standard, but for directors’ functional and educational backgrounds no such
classification was used. The advantage of not using a specific classification system is, especially for
functional background, that classification categories could be chosen towards maximal workability
with the data.
5.2 Further research
Several opportunities for further research exist. Firstly, performing similar research on different
samples: two-tier boards, different countries, SMEs, etc. As the research in this study focussed on a
quantitative analysis, though rather exploratory, further research could scrutinize more thoroughly
several outcomes of this research for the different countries/industries. When doing research on
specific industries, smaller industry-specific samples could be used using interview methods, to find
and check the underlying drivers for these diversity characteristics.
Secondly, when comparing the Blau’s indexes for the several industries, further research might
investigate the complete financial and insurance industry (including banks) separately. I suggest
further research also continues to work with the three diversity dimensions given by Harrison & Klein
(2007), as I believe it contributes to explaining the outcomes of results.
![Page 86: Analysis of the mix of profiles within the boards of ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265893f6e61f734f255d2d4/html5/thumbnails/86.jpg)
73
Thirdly, further research could also establish a link between the diversity characteristics found for
industries/countries and performance. More specifically I believe further research could investigate
whether the value obtained for the Blau’s index (for diversity as variety: educational background,
functional background) has an impact on performance, and can maybe function as a safeguard.
Lastly, when similar studies are regularly performed, further research could also study trends for
diversity variables as educational backgrounds and functional backgrounds or track records.
