Abstract  
Prior studies that dealt with corporate governance mechanisms have witnessed high significant that created some new  
trends. This study aims to be engaged in such trends through investigating the relationship between the board of directors as  
one of the corporate governance mechanisms and firm performance with the presence of managerial ownership as a mediating  
variable in Jordan as one of developing countries. This study used the panel data method to analyze data for a sample of 180  
companies listed on the Amman Stock Exchange (ASE) for the period from 2009 to 2017. Three board of directors dimensions  
are employed, which are: board size, board independence, and CEO duality, and mediating variable is managerial ownership.  
The current study used Tobin’s Q to assess firm performance. Meanwhile, the current study provides evidence that the  
mediating of managerial ownership has a significant negatively on the association between mechanisms of the board of  
directors, which are board size, board independence, and CEO duality with firm performance measured by (TQ). The findings  
of this study confirm empirical research continuing to find a new performance measurement to gain a real form of firm  
performance. Therefore, the evidence of this study provides empirical evidence to stakeholders, managers and interested  
parties to support them for its decision.

Introduction1  
Concerns about corporate governance in many  
directors is more important internal corporate governance  
structure in a company.  
The Board of directors is responsible for maintaining  
the assets to facilitate the completion of the administrative  
work and contribute to the achievement of high efficiency,  
which leads to ensure that the objectives have been  
achieved in accordance with the policies established.  
Where the investor needs to the analysis of the values and  
indicators of market shares, and the most important that's  
values is the rate of return on those investments, where  
returns are a good measure on the performance of the  
boards of directors.  
Thus, it appears as straightforward that identifying  
and analyzing those determinants that influence financial  
performance is of great relevance. While on one hand it is  
logical to suppose that the managerial abilities of the board  
of directors would have a significant impact on the entity’s  
financial performance, on the other hand it is not clear-cut  
whether certain board characteristics regarding its  
remuneration would significantly influence the  
company’s performance (5).  
emerging markets emerged as a result of a series of recent  
corporate accounting scandals across the United States,  
Europe and East Asian (1). Where several interested  
parties around the world tried to face such problems  
through according on corporate governance as a robust  
system to participate in solving its (2).  
The governance structure is mainly tasked with the  
process of distribution of rights and responsibilities  
among different participants in the corporation such as;  
the board of directors, stakeholders, manager, creditors,  
auditors and regulators (3). Thus, the mechanisms of the  
board of directors are one of the constituent mechanisms  
of corporate governance. Where the boards of directors  
participate a fundamental role in corporate governance,  
the structure of the strategic dimensions of the company  
and originate goals (4). Therefore, corporate governance  
depend much on internal structures more than external  
ones for enhancing the firm value. So, the board of

Corporate governance now has become a norm in  
Jordan, where Amman Stock Exchange (ASE) has made  
several changes through issuing a corporate governance  
mechanism in 2009 (6). Revealed by The World Bank  
2.1 Board size and firm performance  
Board size is an important dimension of the board’s  
structure, and there is a need to ensure it is a good fit for  
the responsibilities, needs, and objectives of the  
organization it serves (17). Agency theory suggests that a  
board comprising a larger number of directors is more  
likely to act as a better monitor of the firm’s executive  
management, since having a greater number of directors  
involved in management activities will make the board  
more vigilant (18). As the resource dependence theory  
suggests that larger board size would lead to better  
corporate performance, because of the different skills,  
knowledge, and expertise (19). The results of such studies  
show that the larger the board leads to having expertise,  
knowledge, and effectiveness; thus this will lead to better  
performance (20). Coles et al., (12) used a sample of 8165  
firm-year observations to study the relationship between  
board size and firm performance, they have found that  
board size is positively linked with a high TQ ratio.  
Yasser, Entebang, & Mansor (21) found also that the size  
of the board positively affects the performance measured  
ROE & PM. The study Alabede (22), also found board  
size to be significantly positively correlated with  
operating performance. More specifically, in Jordanian  
non-financial sector, a study was done by Alabdullah,  
Yahya, Nor, & Majeed (23), demonstrates that there is a  
positive relationship between board size and firm  
performance. Thus, the results tell us that a larger board  
size helps to improve firms’ overall value. This can be  
explained by the fact that a large board size would mean  
more − and arguably better − views and decision-making  
following debates on the strategic decisions faced by a  
company in times of difficulty or at times of expansion  
(
2014) that non-financial sector represented by service  
and industrial companies faced a drop in Gross Domestic  
Product (GDP) in the last few years. However, due to the  
poor performance in those sectors, Jordan has faced  
several internal economic, business and social challenges  
besides the global financial crisis, which call for the  
importance of identifying key factors influencing the  
firm’s performance (2). Therefore, so far Jordanian  
companies have not yet reached the phase of full  
compliance with the corporate governance code (7). Thus,  
in 2017, Amman Stock Exchange (ASE) has made modify  
of corporate governance code, through the “compliance or  
penalties” approach rather than the “compliance or  
explain” approach.  
Based on the above explanation, the contribution of  
the current study lies in selecting all sectors constituent of  
Jordanian companies (financial, service, industrial sector)  
excepted banks sector. Thus, the current study aims to  
examine the impact of the indirect relationship of the  
mediate of managerial ownership on the relation between  
the board of directors and firm performance in one of the  
emerging markets namely Jordan. Furthermore, the  
significant role made by the current study is considered as  
an attempt to fill a gap in the previous studies by exploring  
the relationship between the most important mechanisms  
of corporate governance (board of directors) with market-  
based measurement (Tobin's Q).

Literature Review and Research  
(
18).  
On the other hand, Lipton & Lorsch (24) asserts that  
Hypotheses  
In an environment without monitoring and effective  
large board size is less effective compared to small boards  
because there is a tendency to form cliques and core  
groups, thus deteriorating overall cohesion. Kao & Chen  
market regulations, managers are more likely to deviate  
from protecting the shareholders’ interests (8; 9). So, the  
board of directors is viewed as part of the internal  
corporate governance mechanism that plays a key role in  
reducing agency costs arising from the separation between  
ownership and control as a perspective for an agency  
theory (10; 11).  
The corporate board performs two main functions in  
corporate governance. Firstly, monitoring behavior of the  
senior management, company performance to protect the  
interest of the shareholders (12). Secondly, the board  
serves as an adviser to the executive (10). By these roles,  
the success or failure of a company lies with the board  
(
25) have found that larger board size has the potential to  
weaken its functioning, and hence its performance,  
because large boards may be characterized by difficulties  
in achieving efficient communication between members.  
Iturralde, Maseda, & Arosa (26) similarly reported a  
negative effect of board size, arguing that this may be due  
to the disadvantages posed by less effective coordination,  
inflexibility, and poor communication within large boards.  
Al-Manaseer, Al-Hindawi, Al-Dahiyat, & Sartawi (27),  
they found a negative relationship between the board size  
and Jordanian banks’ performance. As researchers also  
found that reasonable board size has been more effective  
in controlling the firm, while a bigger board negatively  
affects the firms’ performance (28). Bansal & Sharma  
(
13). Hence, the quality of the board composition has great  
impact on corporate performance (2). More specifically,  
in Jordanian non-financial sector, a study done by (14),  
demonstrates that there is a positive relationship between  
the board of director and firm performance.  
(
29), they found a negative and significant relationship  
between board size with financial and non-financial  
performance measured by ROE, ROA, Tobin's Q. In a  
study conducted by Zabri, Ahmad, & Wah (30), about the  
Top 100 Public Listed Companies in Malaysia, found that  
board size Negatively and weak effects with performance  
measured by ROA and ROE.  
Company performance is very essential to  
management as it is an outcome which has been achieved  
by an individual or a group of individuals in an  
organization related to its authority and responsibility in  
achieving the goal legally, not against the law and  
conforming to the moral and ethic (15). Performance is the  
function of the ability of an organization to gain and  
manage the resources in several different ways to develop  
a competitive advantage. There are two kinds of  
performance, financial performance and non-financial  
performance (16).

.2 Board independence and firm performance  
The positive effects of board independence on firm’s  
performance have been reported by many researchers  
31). From the agency perspective, independent and non-  
(
executive directors reduce agency conflicts and can act as  
an effective monitoring mechanism for the board (32).  
However, resource dependency theory suggests that a  
761  
Journal of Environmental Treatment Techniques  
2019, Volume 7, Issue 3, Pages: 760-767  
board with more diverse directors could have more  
expertise on how to better operate the firm, thus  
contributing to better firm performance (13).  
Hillman (33) and Masulis, Wang, & Xie (34), they  
examined the impact of the presence of outsiders on firm  
value and accordingly identified a positive association  
between outside board members and corporate  
performance measured in terms of TQ, return on equity  
checks and balances over the activities and performance  
of executive directors  
However, the stewardship theory argues that dual  
leadership provides unparalleled firm-specific knowledge  
of challenges and opportunities that a firm faces and  
increases performance (36). Dual leadership structure  
could also help reduce information asymmetry and may  
ultimately lead to easy access to financial resources; in  
turn, this can reduce the firm’s cost of capital and increase  
its performance (47). Bansal & Sharma (29), they found a  
positive and significant relationship between CEO duality  
with financial and non-financial performance measured by  
ROE, ROA, Tobin's Q.  
Finally, in a study conducted by Al-Amarneh (19),  
found that the duality of CEOs is not important among  
Jordanian banks. Yasser et al., (21), they found a weak  
significant relationship between CEO duality and ROE,  
and non-significant with PM. Detthamrong et al., (40)  
Detthamrong et al., (2017), they find that for an average  
firm CEO duality has no effect on performance. Hence,  
we can say the previous literature revealed mixed results  
on the relationship between CEO duality and firm  
performance.  
(
ROE). As a study Al-Manaseer et al., (27) revealed a  
positive relationship between the number of outside board  
members Jordanian banks’ performance. Likewise,  
Muniandy & Hillier (35) report that board independence  
has a positive influence on firm performance in South  
Africa. Bansal & Sharma (29), found a positive and  
significant relationship between board independence with  
financial and non-financial performance measured by  
ROE, ROA, Tobin's Q. and in line with the proposition of  
the Agency theory, Alabede (22) found a significant  
positive relationship between the proposition of outside  
directors and operating performance. This supports the  
hypothesis that the independent directors are better  
monitors of the board. So, inducting more independent  
directors into the board improves the monitoring and  
advising role of the board (36). Therefore, the relation  
between board independence and firm performance  
depends on the economic and institutional settings in  
which firms operate (37).  
On the other hand, Chugh, Meador, & Kumar (38)  
established that a high percentage of independent directors  
decrease firm performance. In a study conducted by Zabri  
et al., (30) about the Top 100 Public Listed Companies in  
Malaysia, found that board independence no affects with  
performance measured by ROA and ROE. This study has  
revealed that in UAE, the independent directors are not  
motivated to serve the firm’s performance (39). Hence,  
Detthamrong, Chancharat, & Vithessonthi (40) they found  
that for an average firm, Corporate Governance board  
independence has no effect on performance.  
2.4 Mediating effect of managerial ownership  
Managerial ownership has been identified as an  
effective corporate governance mechanism as it helps  
align the interest of managers and shareholders (42).  
According to the agency model, Jensen, M. C., (48) argue  
that there is  
a convergence of interests between  
shareholders and managers as the managers' ownership  
increases, and thus higher managerial ownership should  
reduce agency costs and hence increase firm performance.  
But there exists empirical evidence that the correlation  
between the ownership of the managers and the  
performance of the firm and the value of the market are  
mixed (49).  
Previous studies have revealed findings that  
increasing managerial ownership in the firm is an  
important issue is associated with higher firm  
performance and firm value (50). And a study Fauzi &  
Locke (51) in New Zealand's listed firms, showed that  
managerial ownership has a positive and significant  
relationship with firm performance, suggesting the  
existence of the higher managerial ownership increase  
firm performance. In Jordan context, a study conducted by  
Alabdullah et al., (14) shows that there is a positive  
relationship between managerial ownership and firm  
performance. As found there is a positive relationship and  
highly significant for 109 companies listed at Amman  
Stock Exchange (ASE) for the relationship between  
managerial ownership and financial performance (52). On  
the other hand, Demsetz (53) implies that the increased  
level of insider ownership may reduce corporate  
performance. As Tam & Tan (54) contend that ownership  
2.3 CEO Duality and firm performance  
Firms in which CEO and Chairman of the board are  
separated stakeholders are likely to gain confidence in the  
firms’ ability to raise additional capital and chances of less  
of the bankruptcy of the firm's (41). However, Some  
Researchers agreed that there is no single optimal  
leadership structure because both duality and separation  
perspectives have related costs and benefits. Thus, duality  
will be beneficial for some firms while separation is likely  
valuable for others (42). Thus, A dual leadership structure  
is when the CEO and the chairperson of the board is the  
same person (18).  
There are some theories to explain why some firms  
have chosen to combine the roles of CEO and chairman.  
Agency theory argues that CEO duality hinders the  
board’s ability to monitor management. Fama & Jensen  
(
10) and Jensen (43) argue that CEO duality may hinder  
concentration has a negative relation with firm  
performance in Malaysia.  
the board’s ability to monitor management and thereby  
increase the agency cost. Ehikioya, Rechner, & Dalton  
Researcher far examined the implications of the  
impact of corporate governance on firm performance from  
the perspectives of board structure. And taken into  
account board size, its independence, CEO duality  
assisting the board in arriving at governance decisions,  
which, in turn, has an impact on firms performance. And  
in agreement with a study Noradiva, Parastou, & Azlina  
(55) in respect of the mediating effect of managerial  
ownership, it is possible there the mediating effect of  
managerial ownership on the relationship between the  
(
44), report that firms with a separate CEO and chairman  
consistently outperform firms with combined titles. Gillan  
45) documents that separation of CEO and chairman  
(
would improve the performance of the firm since the  
board has unbiased authority to watch the CEO’s  
functions. As Hashim & Devi (46) pointed out that  
companies should to divided the roles of CEO and  
chairperson to avoid a concentration of power in the hands  
of a single person and to provide an effective system of  
762

board of directors and firm performance. There is also the  
possibility that managerial ownership concentration and  
board composition may be related to each other, and that  
large shareholders may use their influence to select  
directors who are less likely to monitor as a way of  
entrenching themselves (56). Based on the above  
explanation, according to agency theory, resource  
dependence theory, and stewardship theory, the following  
hypotheses were developed:  
H1. There is a positive effect of mediating of  
managerial ownership on the association between the  
board of directors size and firm performance.  
H2. There is a positive effect of mediating of  
managerial ownership on the association between the  
board of directors independence and firm performance.  
H3.There is a positive effect of mediating of  
managerial ownership on the association between CEO  
duality and firm performance.

Board of directors as an independent variable include  
board size (BZ), the total number of members the board of  
directors in the firm during the accounting year. The board  
independence (BDIND), percentage of independent non-  
executive directors on the board of directors. (The  
independent non-executive directors on the board of  
directors to total board size). CEO duality (CEO), CEO  
Duality is defined as the position of the chairman of the  
board and CEO (equals 1 if the role of chairman and CEO  
are combined, and 0 otherwise). Moderate variable  
includes managerial ownership (MAO), and it is the  
percentage of shares held by members of the board of  
directors to the total shares in the company.  
This particular research comprised of selected public  
listed companies on Amman Stock Exchange from 2009  
to 2017. Therefore, companies not listed during the  
investigation period were excluded from the sample  
selection for this research. Therefore, the samples were  
collected based on the availability of the companies which  
had already been listed during the period of the  
investigation. Meanwhile, the second criterion that was  
considered for sample selection was the availability of the  
selected companies’ financial data required for the  
analyses in this study. Besides that, companies which had  
losses in their business transaction activities were also  
excluded from the samples in this research. Furthermore,  
selection of the samples was based on the list of  
companies provided by the Amman Stock Exchange.  
Therefore, the database of Thompson Data Stream was  
used in order to retrieve the data from the selected  
companies. Thus, the final sample that was gathered for  
this particular study comprised of 180 public listed  
companies on Amman Stock Exchange. The type of data  
used in this study is in the form of balanced panel data.  
Hence, from these samples, the total firm years of  
companies tested in this particular study was 1620. For the  
data analyses, the study employed Fixed Effect regression  
method in order to investigate the association between  
selected components with the changes in the firm  
performance in the business organization. Based on table

.1 Study population sample and resources of data  
The data of the current study consists of the public  
shareholder's companies listed on the Amman Stock  
Exchange (ASE), excluding banks sector. And in order to  
ensure the robustness of the research and that the  
dimensions of the Corporate Governance were taken  
based on the local Corporate Governance dimensions  
rather than general or international dimensions of  
Corporate Governance. As the Corporate Governance  
scoring was based on Jordanian Corporate Governance  
guide issued in September 2009. So, studied Jordanian  
companies for nine consecutive years of reporting periods  
from 2009 to 2017.  
The data set of the current study comprises financial  
and non-financial information for the companies listed on  
ASE through the period 2009-2017, collected from the  
available annual reports published on ASE website and of  
DataStream site. Where, used the quantitative method in  
the current study, and used secondary data to data  
collected. So, the study sample consisted of 180  
companies from the financial, industrial and service  
companies, has been summarized in Table 1.

Based on the Table3, the results were depicted as  
there is a negative relationship between all the selected  
components towards the changes in the firm performance  
in the business organization. These results were explained

.2 Measurement of Variables and Descriptive Statistics  
The objective of this study at investigating the impact  
of mediating of managerial ownership on the relation  
between the board of directors and firm performance, to  
analyze the performance of the firm, the current study  
used Tobin’s Q as a measure of the dependent variable.  
TQ (Tobin, 1969) is a combination of different accounting  
as well as market values via considering the value of the  
market of a firm. Tobin's Q, as a result, is a powerful tool  
to utilize, since it analyses corporate performance from a  
market perspective, a market-based measurement which is  
categorized as long term, and therefore reflects the present  
value of future cash flows based on current and future  
information (57). Thus, Tobin’s Q = [The ratio of the  
book value of total assets  (the book value of total equity  
6.808, p = 0.000.

The result is inconsistent with the hypothesis that  
supports mediate positive of managerial ownership on the  
relationship of board size with the firm performance (TQ),  
hence H1 is rejected. The result of this study agrees with  
the previous study done by (30; 29). On the other hand,  
the result of this study disagrees with the previous studies  
such as (18; 21). According to the resource dependence  
theory that larger board size leads to better firm  
performance, because of the different expertise and  
members skills. As the agency theory suggests that a board  
of directors larger is giving more activity to act as a better  
observer of the management.  
by Tobin’s Q. The finding reveals that found that board  
independence has negative and high significant  
a
relationship at 1% level with the firm performance (TQ),  
β = -9.59 t = 1.377, p = 0.0015. Thus, the result is not  
regular with the hypothesis that supports a positive of  
mediate of managerial ownership on the relationship  
between board independence and firm performance.  
Therefore, H2 is rejected. This finding agrees with the  
previous studies such as (58; 29). And this finding  
disagrees with studies by (23; 59). The independence of  
the board of directors members are negatively related to  
firm performance which suggests that by having more  
independent directors on the board lead to weak in firm  
performance. And in line with the proposition of the  
Agency theory, the basic role of an independent member

is to supervision the governance of a business, having too  
many independent members of the board may endanger

This study supports that mediate of managerial  
ownership has negatively related to the relation between

mediate of managerial ownership has a significant  
negative on relate CEO duality with the firm performance  
performance, this can be done by relying on a strong  
corporate governance system that can lead to an  
improvement in Jordanian companies to lead Jordan's  
economic growth for the improvement in the future.  
Finally, the current research is  
a
response to  
recommendations from previous studies for make new  
research that aims to study other mechanisms of corporate  
governance with firm performance among public listed  
companies in the Jordanian capital market such as (60;  
61).

suggests that if the duality between CEO and chairman  
could weaken the firm performance. This negative  
significant relationship not regular with H3, thus H3 is  
rejected. The current result agrees with the study done by

Conclusion  
The current study provides evidence on the influence  
(
45; 10; 14). While disagreeing with previous studies such  
the mediating of managerial ownership on the relationship  
between the board of directors as one of the corporate  
governance mechanisms and firm performance of public  
listed companies on the Amman Stock Exchange. Where,  
the purpose of the present study was to examine the  
mediating effect of managerial ownership on the  
relationship between the board of directors’ mechanisms  
as (36; 47; 29). According to agency theory that CEO  
duality handicap the board’s ability to observe  
management. Meanwhile, stewardship theory support that  
dual leadership provides perfect knowledge to managers.  
This study provides evidence that managerial  
ownership is a positive effect on the relationship between  
the board of directors and firm performance. The model  
on above, explains that managerial ownership has  
significant negative on the relationship for the board of  
directors and firm performance (TQ), β = -0.000624, t = -  
(
board size, board independence, and CEO duality) and  
firm performance of Jordanian companies.  
This study comprised of selected public listed  
companies on the Amman Stock Exchange from 2009 to  
6.543934, p = 0.000 which suggests that if the managerial  
2017. Therefore, the samples were collected based on the  
ownership is high, it could weaken the relationship  
between board of director and firm performance. Agency  
theory supports that higher managerial ownership should  
decrease agency costs and leads to better firm  
performance, but the current study provides evidence that  
managerial ownership negatively influences the  
relationship between the board of directors and firm  
performance.  
Based on Figure 1 above, it was also showed as the  
model tested in this particular study was stable. This  
particular evidence also indicated as the result of the  
findings was robust and it was significant to be addressed  
in this particular research. Moreover, Figure 1 represents  
the trends in the board of directors among the selected  
companies.  
availability of the companies which had already been  
listed during the period of the investigation and financial  
data required for the analyses in this study for the selected  
companies’. Furthermore, the database of Thompson Data  
Stream was used in order to retrieve the data from the  
selected companies. Thus, by using the panel data method,  
the final sample that was gathered for this particular study  
comprised of 180 public listed companies on the Amman  
Stock Exchange for 1620 firm years. Where the study  
employed the Fixed Effect regression method in order to  
investigate the association between selected components.  
Based on the findings, found a significant negative effect  
of managerial ownership on the relationship between the  
board of directors (board size, board independence, and  
CEO duality) with firm performance measured by (TQ).  
Which suggests that if the managerial ownership is high,  
it could weaken the relationship between the board of  
director and firm performance.  
In addition, the suggestion for future researches may  
include more variables for the board of directors, such as  
board activity and experience of members, and  
investigation in other mechanisms of corporate  
governance and its effect on firm performance. Future  
researchers can also be using different performance  
measures, such as ROA, ROE, and market share. Future  
researches may include examining long periods before  
and after the reform of corporate governance in Jordan.
