Abstract

The appropriate establishment of corporate governance mechanisms is a basic step for the

optimal use of resources, improvement of accountability, transparency, and observance of

equity and rights of all beneficiaries in the company. Each of the mechanisms within and

outside of the organization supervises companies’ processes and activities and leads to the

increase of accountability and achievement of other corporate governance objectives. One of the

mechanisms is focus and ownership structure. Financing is done through different short-term

and long-term methods from internal and external resources. Now, this question is posed that

whether or not there is a significant relationship between the ownership structure, corporate

growth and financial strength, with corporate financial leverage. In this research, the

relationship between the ownership structure, corporate growth and financial strength, with

corporate financial leverage is addressed in companies being accepted in Tehran Stock

Exchange using deducted simultaneous equation systems and panel data relating to 2007 –

2011. Generally, research findings indicate a relationship between the ownership structure,

corporate growth and financial strength, and companies ‘administrative financial leverage.

Keywords: capital structure, firm growth, financial strength, financial leverage

INTROUCTION

In the financial decision making process, capital is an important source along with other

sources. Basically, capital can be divided into equity or non-equity capitals. These two show

assets and debts of the company. The combination of these two is called the financial leverage

and varies in different conditions such as capital costs, capital market, management perspective,

organizational strategies, company size, growth, etc. In this regard, the capital structure is an

attractive domain in financial management and financial affairs. Many of decision making

processes are decision making factors at the time of determination of capital structure. Different

issues such as expenses, various taxes, tax rate and interest rate are proposed that explain the

changes in financial leverage of companies. Changes in the capital structure have massages for

different individuals in the company. Financial decision making is one of the important

functions which helps financial managers to decide when, where and how to supply credits for

investments (Zhao et al, 2012). Institutional investors are the main actors in financial markets.

As institutional investors’ influence on the corporate governance has been increased following

privatization policies accepted by different countries, it can be concluded that they are

significantly important in many of corporate governance systems. Owners (company

shareholders) have different rights, including the selection of the board of directors that acts as a

representative for supervising the performance of the company managers. On the other hand,

major shareholders have a significant role in transferring information to other shareholders.

They can obtain private information from the management and transfer information to others

(Najjar & Tyler, 2008). The agency theory suggests that the capital structure and the optimal

ownership structure can reduce the agency costs. So, it is expected that there is a relationship

between the capital structure and the ownership one (Asadi, 2011). The company performance

depends on a number of factors. One of the most important factors is the financial strength of

the company which directly affects its ability to improve. The evaluation of financial strength of

the company is very useful for individuals interested in the corporate growth. Identification of

financial problems and the company’s ability is an issue which is extremely subject to the

analysis of financial ratios. The insufficient profitability or bankruptcy experience in a company

may be considered as a potential financial problem, but the inadequate settlement condition may

be considered as a serious problem. There is a difference between the financial strength of a

bankrupt company and that of a healthy company. There are two types of financial strength:

short-term and long-term. The short-term financial strength affects the profitability, liquidity

and structural health of the company. It can be achieved by managing current assets or current

commitments or by managing the working capital of the company. The working capital of the

company is consisted of the permanent working capital and the variable working capital. If a

company obtains the short-term financial strength, it can achieve the three objectives of

sufficient liquidity, risk reduction and increase of the company's value (Zhao et al, 2011). Now,

the research question is that whether there is significant relationship between the ownership

structure, corporate growth and financial strength, and financial leverage of companies being

accepted in Tehran Stock Exchange?

Research Literature

Decision making on the type of financing and capital structure of a company has a critical and

important role in its prosperity and financial position. An improper decision on the type of

financing and capital structure can lead to the company’s financial limitation, liquidation and

bankruptcy. Therefore, it can be said that decisions on the type of capital structure are important

decisions of a company and a proper capital structure allows the company to remain stable in

the competitive environment (AL.Shabiri ,2010).

Since most of empirical researches in this area are related to developed countries which have

similar institutional features, considering the issue of capital structure and ownership structure

in developing countries has a significant importance. Therefore, study of the relationship

between the ownership structure and capital structure in our country can be a basic step in order

to create an appropriate context for future researches.

Akhtar (2005) studied the factors which affected the determination of capital structure of

multinational and domestic companies of Australia during 1992 to 2000 using time series cross-

sectional regression. Results indicate that in all of these companies, growth and profitability

opportunities, and the company’s size are components which determine the debt ratio. When he

conducted his study divided into industries, he found out that these factors were more important

in some industries.

Tesai and Gu (2007) studied the relationship between the institutional ownership and

companies’ performance during 1999 to 2003. This research showed that the institutional

investment in companies may help investors to address the problems of the agency resulted

from the separation of management and ownership. In addition, financial institutions tend to

invest in larger companies with less financial leverage.

Najjar and Tyler (2008) studied the relationship between the ownership structure and capital

structure for companies being accepted in Tehran Stock Exchange. Their research results

indicate that there is no significant negative relationship between the capital structure and

institutional investors. They suggested that a mechanism for the external control which affects

the corporate governance is the emergence of institutional investors as capital owners.

Institutional investors supervise the company implicitly through data collection and

management decisions pricing and explicitly through the control of company’s performance.

Hassan et al. (2009) also showed that the size the board of directors and institutional

shareholders had a significant negative relationship with debt – equity ratio.

Larry (2010) studied the relationship between the ownership structure and the type of

company’s participation with capital structure. This study was conducted in China during 2000

to 2006 using panel data and multivariate regression with the sample size of 789 companies.

The result of this study indicates the less use of financing through debts in companies in which

governance system mechanisms are implemented at a high level. In addition, the type of

industry in which the company participates has positive effects on the capital structure following

the ownership structure and corporate governance mechanisms.

Zhao et al. (2011) attempt to expand the knowledge of financial leverage, corporate growth and

financial strength of companies being accepted in Sri Lanka stock exchange during 2000 to

2009 in an article. The key research question is that whether the effect of financial leverage on

the corporate growth is positive or negative. Results indicate that there is a positive relationship

between the financial leverage, and the corporate growth and financial strength. In addition, it

reflects the view that there is a positive relationship between the financial leverage and other

growth variables which have shown that the future growth of the company was negative.

Al Ali(2009) studied the relationship between the capital structure and ownership structure, and

determined some features which affected the capital structure. The result shows a significant

relationship between the capital structure and ownership structure. .

Hashemi and Bekrani (2011).studied the relationship between the capital structure decisions,

and ownership structure and corporate governance system. Results of data analysis verified

hypotheses of the study and finally, the main hypothesis of the study was verified using

combined data. In other words, there is a significant relationship between the corporate capital

structure decisions, and the ownership structure and the corporate governance system.

Asadi et al. (2011). studied the relationship between the capital structure and the ownership

structure in companies being accepted in Tehran Stock Exchange. In order to test the hypothesis

using the panel data statistical method, it was attempted to provide four patterns based on

variables. The empirical evidence indicates that there is a significant negative relationship

between the capital structure and the ownership one. According to results, although it is not

clear that whether the capital structure leads to the ownership structure or vice versa, it seems

that investors and creditors must consider the capital structure and or the ownership structure at

the time of decision making on the investment and accreditation.

Rahmani et al.(2011). studied the effect of the type of ownership structure on the corporate

performance. Results of hypotheses test using regression test indicates that the ownership

structure affects the corporate performance.

Sadeghi et al.(2012). studied the relationship between the ownership structure and the

performance of companies being accepted in Tehran Stock Exchange using deducted

simultaneous equation systems and panel data relating to 2003 – 2009, and research hypotheses

test indicates that in Tehran Stock Exchange, focus and ownership structure do not affect the

performance of companies being accepted in Tehran Stock Exchange, but the corporate

performance has a significant effect on the ownership structure.

The main hypothesis

There is a significant relationship between the ownership structure, corporate growth and

financial strength, with corporate financial leverage.

Sub hypotheses

1. There is a negative relationship between institutional ownership and corporate financial

leverage.

2. There is a positive relationship between profit growth and corporate financial leverage.

3. There is a negative relationship between Sales growth and corporate financial leverage.

4. There is a positive relationship between Asset growth and corporate financial leverage.

Method of Data Collection

Research Method:

This research is inductive, quantitative, field, applied and quasi experimental, and is conducted

using ex post facto (through past information).

Statistical Population and Sample, and Data Collection:

In order to conduct the study, all companies being accepted in Tehran Stock Exchange were

considered as the statistical population which included 463 companies until the end of 2011, and

the statistical sample was extracted from among these companies. In this research, the statistical

population consists of companies which have the following features:

1. The company’s stock should be transacted in Tehran Stock Exchange from 2007 to 2011

(5 years) and it should have a continuous activity.

2. The company should not have any change in the activity during the mentioned fiscal

years or should not have any change in the fiscal year.

3. The company should not be a part of banks or financial institutions (investment

companies, financial intermediary, holding companies, leasing). (Elimination due to the

specific nature of the activity and return of investment companies is also imposed in

other subgroup companies).

4. The fiscal year of all companies should be on March 20.

5. The company should not have operating loss during these years and consequently, the

dividend should be distributed in cash.

6. The required data should be available.

7. Finally, according to the aforementioned features, 140 companies were selected for the

research during 2007 to 2011.

140 companies which were the members of population were selected as the sample.

Descriptive Statistics:

Features relating to variables used in the research, including dependent variables were presented

separately. Statistics for the variables used in the research include mean, median, maximum,

minimum, standard deviation, skewness, and Jarque – Bera test. Because of the difference

between mean and median in some data and due to significance (probability) level of less than

5% in Jarque – Bera test for variables, there is a need for the adjustment and normalization of

data. As some variables were normal, by using Johnson’s data convert Minitab software, the

above variables were normalized with the probability level of more than 5% and the slight

difference between the mean and median showed the normalization of observations.

The Correlation Test:

According to the above hypotheses, the correlation coefficient calculations are done two by two

for the research variables in the following table, and as it is observed, there is a negative

relationship between the financial leverage, and institutional ownership and other explanatory

variables, and the percent of the relationship with the financial strength is more than other

variables. The market financial leverage has also a negative relationship with institutional

ownership and other variables, and the percent of the relationship with the financial strength is

more than other variables. In addition, the market leverage has a direct relationship with the

natural logarithm of the number of shares and according to the correlation coefficient of 24%

and 32%, there is the probability of linearity between the financial strength variable, and assets

growth and sales growth. Consequently, through the linear regression analysis ad test based on

the suggested models, we estimate and analyze coefficients.

1. Financial Leverage:

Leverage is the existence of fixed costs in the list of the company’s expenses. The financial

leverage is calculated through the total debts divided by the total assets. In this research, the

financial leverage is used in two ways:

1. Total debts divided by the book value of assets

2. Total debts divided by the market value of assets

The Ownership Structure:

The ownership structure means that which (natural/legal) persons have influence and

domination on the operational and strategic decisions of a company. Two indices are considered

for the ownership structure: The first one is the natural logarithm of the number of shares for

institutional investors, and the second one is the institutional ownership percent from shares

which is obtained by the number of shares for institutional investors divided by the total shares

of the company (Asadi et al., 2011).

2. The Corporate Growth:

Growth is defined as a change in the annual percent of total assets, sales and profit. The

corporate growth shows an expansion in the company’s activities in terms of sales, profits and

assets (Zhao, et al, 2012).

(selected year value( total asset .profit. sale) - Based year value(total asset . profit. sales)) / Based year value(total

asets. profit .sales)

3. Financial Strength:

The company’s performance depends on a number of factors. One of the most important factors

is the financial strength of a company and it directly affects the ability of the company to

develop (Zhao et al, 2012).

Endogenous variables: LEV,IO

Exogenous variables: PG,SG,Z,AG

Results of diagnostic tests indicate that the models used are of the type of fixed effects.

According to the diagnostic tests, we use the fixed effects model to estimate the model

coefficients and also, because patterns are precise and the number of instrumental variables is

more than endogenous variables, the two-stage least squares method is used. In order to test

patterns, in the first stage, the reduced patterns, the third and fourth equations are separately

estimated through the least squares method, and in the second stage, the first and second

equations are fitted. Before the estimation of the first and second patterns, the following

variables were estimated instead of endogenous variables (LEV & IO) according to the residual

of the third and fourth equations and they were used as explanatory variables.

IOHAT = IO – RESID3

LEVHAT = LEV – RESID4

RESID3 :The remaining third model

RESID4: The remaining four models

Autocorrelation Test:

According to results of Durbin-Watson test, in all patterns, there is the probability of

autocorrelation. Based on the type of data (panel data), Volderij test (autocorrelation test) is

conducted for the above four patterns.

H0: There is a correlation

H1: There is no correlation

According to the probability level, there is autocorrelation in less than 5% of most patterns.

Therefore, due to the autocorrelation, the FGLS method is used to estimate the autocorrelation

condition through Stata software and their coefficients are obtained.

According to results of the first and second patterns hypotheses test which was conducted based

on the existence of autocorrelation, the regressions model is verified at the confidence level of

95%.

Research Conclusion and Suggestions:

Identification of the capital structure of companies in the stock exchange is very important

which from different actors’ points of view, the stock market is used in many different ways. As

it was mentioned in the research objectives and as it was verified in the analyses, the capital

structure is influenced by the growth (sale, profit and asset) and financial strength.

1. The research suggestion is based on the result of the first sub-hypothesis and the

negative relationship between the institutional owners and the administrative financial

leverage. According to these results, companies owned by institutional investors tend to

use less financial leverage because this high financial leverage shows financial risks. It is

suggested that investors invest where institutional owners are high because high

institutional owners lead to the less financial leverage. These findings can be optimally

used in decision makings.

2. According to results of the second sub-hypothesis and the negative relationship between

the profit growth and the administrative financial leverage, it is suggested that

companies with a high profit growth reduce the utilization of the financial leverage in

their financing, and investors invest in companies with a higher profit growth because

there is a lower financial leverage and also lower risks and bankruptcy.

3. According to the third sub-hypothesis and the positive relationship between the sales

growth and the administrative financial leverage, it is suggested that companies with a

higher sales growth can use the debt financial leverage to financing ratio for financing

through more funds.

4. According to the results of the fourth sub-hypothesis and the positive relationship

between the asset growth and administrative financial leverage, it is suggested that

companies with a higher asset growth use more leverages for their financing.

5. According to the result of the fifth sub-hypothesis and the negative relationship between

the financial strength and administrative financial leverage, it is suggested that

companies with a low financial strength avoid using financial leverage because a high

financial leverage increases the probability of the company’s bankruptcy and financial

crisis, and investors invest in companies with a high financial strength; on the other

hand, there is a lower financial leverage in these companies and consequently, the

financial risk is lower, too.

Suggestion for future research

1. As research results confirm the hypothesis on the relationship between the financial

growth and strength with the financial leverage, models proposed in this research can be

studied more and new variables can be added such as foreign institutional investors or

foreign companies and or considering different computational standards for the financial

leverage, new models can be studied.

2. In addition, in this research, it is not clear that which variables cause others; so, it is

suggested that in a separate research, it becomes clear that for investment or

accreditation decisions, which one is considered to be the causative agent for the other.

3. Because of the difference among results of hypotheses test, the administrative financial

leverage and the market financial leverage, it is suggested that more researches must be

conducted in order to study these instrumental variables simultaneously.

4. As the ownership structure has different indices, including institutional ownership,

managerial ownership, corporate ownership, etc., in this research, we only used the

institutional ownership as the index of the ownership structure based on the research of

Najjar and Tyler. It is suggested that in another research, other indices of the ownership

structure are used.

5. The effect of industry and macro-economic and political variables can be entered into

the pattern, and studied and analyzed.

6. Study of the financial leverage of small companies and its effect on the companies’

growth
