3.2 Board characteristics and Capital Structure
3.2.5 Independence Percentage of non-executive directors
The encouragement of good corporate governance has led to the creation of non-
executive directors (NEDs), who form part of the Board of Directors. In the UK, a
unitary board exists in companies, the board is made up of EDs and NEDs, also known as
insiders and outsiders. EDs are employed on a full-time basis by the company, with the
overall aim to oversee the daily running of the company, the transition to this role is
through internal promotion. NEDs are not full-time employees of the company, and are
appointed from outside of the company. Their role is to attend the monthly board
meetings, enhance shareholder value and provide a monitoring role (Institute of
Directors). In accordance with the Institute of Directors definition of director
independence, it occurs when directors have not been full-time employees, in addition the
directors hold no shares in the company whose board they sit on (Institute of Directors).
The introduction of the SOX Act in 2002 as a consequence of the global financial
scandals such as Enron and WorldCom, has meant that the NED role has become a
pivotal one to companies not only in the United States, but across the UK as well. The
NED role is not a direct result of the Cadbury (1992) report as it was the norm for
companies to be run by part-time NEDs. The guidelines state an NED is available to
work 100 hours per year (Charkham, 1994), while guidelines as to the number of boards
95
recommends significant changes to the board composition, these include an increase in
diversity, and the requirement that board members should have business and board level
expertise. The guidelines state that at least 50% of board members should be
independent. NEDs are also known as outsiders, independent and supervisory directors.
Hart (1995) states that ‘NEDs may owe their position to management.’ The appointment of NEDs in the UK is seen as controversial. Following the guidance of the Hampel report
(1998), The Higgs report (2003) indicates the process of appointing NEDs has high levels
of informality attached to it. “Almost half of the NEDs surveyed for the Report were
recruited to their role through personal contacts or friendship. Only 4% had a formal
interview, and 1% had obtained the job through answering an advertisement.” The
implications are that only quiet NEDs are appointed onto the Board of Directors (Hart,
1995), preventing the monitoring role from occurring. In the UK, 44% of boards consist
of NEDs (Peasnell et al., 2003), with 31% of the board being defined as independent. In
contrast, in the US, outside directors make up 76% of the board (Bhagat and Black, 1999)
and 77% (Klein, 1998).
The boards’ main role is to be vigilant; this can be increased due to the presence of NEDs. NEDs are seen as independent, and are not employed full-time by the company,
neither are they affiliated to the company whose board they sit on (Hermalin and
Weisbach, 1988). The central aspect of monitoring is to focus on the financial
performance of the company (Fama and Jensen, 1983). NEDs are more likely than
insider directors to dismiss CEOs following poor performance (Coughlan and Schmidt,
1985), and through maintaining their own reputation as directors, have an incentive to
monitor the board they sit on. In the UK, directors do not have fiduciary duties; NEDs
view their role as advisory as opposed to disciplinary (Franks et al., 2001). In the US,
96
fulfill their fiduciary duties, this is in contrast to the UK (Ozkan, 2007). NEDs are
delegated monitors who are appointed by the shareholders to monitor the manager’s use
of the company’s resources (Hart, 1995). NEDs concern for their reputation and future career opportunities, ensure directors are effective monitors (Fama and Jensen, 1983).
Agency theory (Jensen and Meckling, 1976) is still a valid theory; directors are motivated
to act in the interests of shareholders in situations whereby they have significant
ownership in the company (Morck et al., 1988; Jensen, 1993). Rosenstein and Wyatt
(1990) find for US companies that NED appointments lead to significant increases in
shareholder wealth; the relationship with capital structure is mixed, in terms of its
direction and significance. Previous literature suggests theories on how boards are
developed. Firstly, firm specific characteristics, such as company size, age of the
company, cashflows and scope of operations can determine how the board is shaped.
Secondly, owner specific characteristics that ensure the bargaining process between EDs
and NEDs occur.
A Board of Directors that contains a high percentage of outside directors performs a
monitoring role of the CEOs behaviour, and ensures incentives offered to the CEO are
also in the shareholder’s interests (Fama and Jensen, 1983). Young (2000) and Peasnell et al. (2003) find evidence that firm specific variables influence the board composition. Larger companies who have lower growth prospects are more likely to adhere to the
Cadbury Report recommendation on the number of NEDs. The period before equity
issuance, and following the departure of the CEO, also encourages companies to comply
with corporate governance guidance.
Previous literature has focused on the relationship between the number of outside
97
small positive relationship; Wagner et al. (1998) find an inverted U-shaped relationship,
while Dalton et al. (1998) find no significant relationship. One study (Dahya and
McConnell 2007) that considers the period following the release of the Cadbury Code,
1989-1996, finds improvement in the performance of UK companies. Companies that
add directors in line with the guidelines, report a significant improvement in operating
performance (Dahya and McConnell, 2007). In a study of UK companies Weir et al.
(2002) find a negative relationship between the percentage of NEDs and company
performance. Weir et al. (2002) find weak evidence between the structure of the board
and the performance of UK listed companies, arguing that companies should be given
greater freedom over the control mechanisms that they adopt. The difficulty with greater
choice is the ability to assess which controls are effective in ensuring good corporate
governance occurs. The impact on capital structure for UK companies has been
researched in previous UK studies; Faccio and Lasfer (1999) find a weak relationship for
a one-year time period, 1996/1997. The focus of this study is on the relationship between
the percentage of NED’s and capital structure with more recent data. 3.2.5.1 Percentage of NED’s Hypothesis
Agency theory (Jensen and Meckling, 1976) drives the relationship between the
independence of the board and capital structure, to avoid control of the decisions being
held by one person to ensure capital efficiency occurs. The choice between debt and
equity surrounds the different risk levels, and the additional uptake of debt should be
considered in relation to existing levels of debt. The risk of default increases as debt
levels increase, therefore the role of the NED’s is to ensure the managers are looking after the needs of the shareholders. The uptake of positive net present value projects is key to
98
NED’s provide an independent discussion surrounding the options available regarding capital.
In this study, the variable board composition is the percentage of NEDs a company has,
which is expressed as a percentage of the number of directors in total. Following the
guidance of the Hampel report (1998) the increase in NEDs for monitoring and control
purposes is seen as irrelevant, excessively costly and presents a threat to board unity
(Young, 2000). The impact of the increase in the percentage of NEDs on UK boards still
remains open for debate, this study seeks to identify whether the composition of the board
is one factor that contributes to a company’s choice between debt and equity.
As the number of NEDs increases, it translates to higher levels of monitoring, and leads
to the expectation of a negative relationship. The implications are managers wish to
avoid the high level of monitoring, therefore leading to the avoidance of high leverage
levels. Therefore, in line with Weir et al. (2002), to avoid the pressures and increases in
monitoring levels that are associated with servicing debt, a negative relationship is
expected.
The hypothesis is:
H11: There is a negative relationship between board independence and leverage.
