ABSTRACT

Financial structure is financing decision undertaken by a firm on the course of funding its

corporate investment. This entails the combination of debt and equity capital to finance firm’s

assets. The impact of financial structure on firm performance has been ambiguous due to

extensive arguments from diverse perceptions. The subsisting empirical study to prove the

impact of debt and equity mix on firm performance in Nigeria is narrowed to capital structure

measures with established contradictory views inferred from the inconsistencies among their

findings. Thus, the results and conclusions on the studies may be misleading. Financial structure

measures have a better chance to acquiesce unbiased result, because of different empirical

implications in regard to different types of debt instruments. However, in underdeveloped debt

market peculiar to Nigeria, most firms’ external debt finance is majorly short term finance,

imposing extra burdens at very exorbitant costs on the firms. It is on the premise of the foregoing

arguments that this study sought to evaluate the impact of financial structure on the performance

of quoted firms in Nigeria. By examining the impact of : (i) total debt ratio on performance of

quoted firms in Nigeria, (ii) long term debt ratio on performance of quoted firms in Nigeria and

(iii) short term debt ratio on performance of quoted firms in Nigeria. The study adopted ex-post-

facto research design. Panel data collated from the annual reports of 51 sampled firms and

Nigeria Stock Exchange factbooks over a 12 year period (2001-2012) were employed. Data were

subjected to pool Ordinary Least Square (OLS), Fixed Effects, and Random Effects regression

model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR),

long term debt ratio (LTDR) and short term debt ratio (STDR) were adopted as independent

variables. Firm performance as the dependent variable was proxied by return on asset (ROA).

Results emanating from the tests of the three hypotheses reveal that total debt ratio have

negative and significant (coefficient of TDR = -0.0776, p < 0.05) impact on the performance of

Nigerian quoted firms; Long term debt ratio have negative and significant (coefficient of LTDR

= -0.0479, p < 0.05) impact on the performance of Nigerian quoted firms; and short term debt

ratio have negative and significant (coefficient of STDR = -0.0804, p < 0.05) impact on the

performance of Nigerian quoted firms. Based on these findings, the study concludes that

financial structure is relevant in explaining variations in the performance of Nigerian quoted

firms. Accordingly, the study therefore recommends among other things that government should

pursue genuinely a policy measures targeted at developing the security market to ensure high

volume of corporate debt issue, liquidity of market and market efficiency in order to guarantee

easy mobilization and allocation of funds. As a strategy, they should aim at reviewing existing

restrictions which are detrimental to corporate debt issue and rather provide assistance in

raising long term capital via capital schemes and loan subsidies that will in turn drive market

interest rate of external debt capital. This will in turn drive positively the financial structure

decisions of firms’ agents.

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Financial structure is financing decision undertaken by a firm on the course of funding its

corporate investment. This entails the combination of debt and equity capital to finance firm’s

assets. The inherent risks in business environment has contributed to every corporate organization

aligning its’ financing decision towards achieving supreme objective. Abu-Rub (2012) contends

that financing decision vary according to the rate of risk related to each financing options as well

as the relationship between risk and return. Firm seek to adopt a mixed financial structure that

guarantees minimum cost to achieve the main goal of maximizing firm’s performance. The impact

of financial structure on performance of a firm has been ambiguous due to extensive debate from

diverse perceptions. The core argument among scholars is in two fold; irrelevance and relevance

theories of financial structure. The former argue that under very restrictive assumptions of perfect

capital markets, investors’ homogenous expectations, symmetric information and no bankruptcy

cost, financial structure does not determine performance of a firm. While, relevance theories with

imperfect capital markets assumptions have modeled and evidently revealed negative and positive

significant relationship between financial structure and performance of a firm (see for example,

Zeitun and Tian, 2007; Onaolapo and Kajola, 2010; Skopljak and Luo, 2012).

Nevertheless, Modigliani and miller (1958) argue that “the market value of any firm is independent

of its financing decision and is given by capitalizing its expected return..., and average cost of

capital to any firm is completely independent of its financing decision and is equal to the

capitalization rate of a pure stream of its class”. The unrealistic nature of MM propositions

coupled with their subsequent work in 1961 and 1963 triggered controversial arguments. This

however, spawned the interest of many scholars who looked at diverse dimension to examine the

effects of less restrictive assumptions on the relationship between financial structure and value of a

firm (Eriotis, 2007). Subsequent work of Miller (1977), presented a new challenge by pointing that

under certain conditions, the tax shield benefit of debt financing at the firm level is exactly off set

by the tax disadvantage of debt from personal income tax. Modigliani and Miller theorems

however, assumed that investors and firms have equal access to financial markets, which allows

for homemade leverage (Brealey and Myers, 1996). As argued, investors can create any leverage

Page 15: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

they wanted but not offered, or the investors can get rid of any leverage that the firm took on but

was not wanted. Hence, firms’ leverage decisions do not influence its’ value (Afrasiobi and

Ahemadina, 2011). The advocates of Modigliani and Miller theorem have provided empirical

evidence that capital structure is insignificant (for example, Adelegan, 2007, pratheepkanth, 2011)

amongst others.

Conversely, most recently held theories with their varying predictions are evident in the world of

imperfect capital markets where internal and external capital is not perfectly substituted. Thus

relevance theories suggest that many factors such as tax effects, agency effects, bankruptcy costs,

signalling effects, market timing and asymmetric information influence financing decisions and in

turn the value of the firm (Jensen and Meckling, 1976; Myers and Mauflis, 1984; Myers, 1984;

Ross, 1977; Leland and Pyle, 1977; Kim et al., 1977; Fama, 1980 and Fama and French, 1998).

Specifically, these theories that have been advanced to explain the financial structure of firms

include the pecking order theory, tradeoff theory, the agency cost theory, signalling hypothesis,

market timing hypothesis, neutral mutation hypothesis, among other. Although various schools of

thought emphasize on different elements, it is probably fair to say that a consensus is emerging

(Kim and Babbel, 1995).

In this view, the key issues among the theories can be narrowed down to maximization of

shareholders’ value. The separation of ownership and control in a professionally managed firm as

assumed by agency cost theory may result in managers exerting insufficient work effort, indulging

in perquisites, choosing inputs or outputs that suit their own preferences, or otherwise failing to

maximize firm value (Jensen and Meckling, 1976). Consequently, the agency costs of outside

ownership equal the lost value from professional managers maximizing their own utility, rather

than the value of the firm. Theoretical body of knowledge suggests that the choice of financial

structure may help mitigate these agency costs. Debt finance act as a controlling tool to restrict the

opportunistic behaviour for personal gain by managers. It reduces the free cash flows with the firm

by paying fixed interest payments and forces managers to avoid negative investments and work in

the interest of shareholders. But if an investment yields large returns, shareholders capture most of

the gain. If, however, the investment fails, debt holders bear the consequences. As a result,

shareholders may benefit from investing in very risky projects, even if they are value-decreasing

“asset substitution effect” (Jensen and Meckling, 1976). Apparently, when leverage becomes

relatively high, further increases generate significant agency costs of outside debt; including higher

3

expected costs of bankruptcy or financial distress, arising from conflicts between bondholders and

shareholders. In the same view, trade-off theory advocates that firm leverage ratio is driven by

three competing forces such as tax benefits, bankruptcy cost and agency costs (Nosa and Ose, 2010

and Huang and Ritter, 2004). Also at high leverage the value of shareholders may not be enhanced

when restrictive covenants included in debt financing agreements limit the ability of firms to fully

harness the potentials of the firm’s resources (Onwumere et al., 2011). Thus firm maximize their

values by maximizing the use of debt. Regarding the possibility of financial structure influence on

firm performance due to agency costs and other cost of debt, several researchers have conducted

empirical studies that aim to examine the impact of financial structure on the firm performance

over the last decades (see Zeitun and Tian, 2007; Onaolapo and Kajola, 2010; Skopljak and Luo,

2012; Akbarpour and Aghabeygzadeh, 2011; Berger and Patti, 2002; Ebaid, 2009) among others.

The trade off theory states that in choosing leverage ratio, firms seek to balance the benefits of

debt against the potential costs of financial distress that is made more likely at high debt levels

(Bunn and Young, 2004). While, pecking order theory argued that firms do not try to reach the

“optimal” capital structure, as the trade-off theory claims, because firms employ least resistance

and least costly financing mix (Kasozi and Ngwenya, 2010). Thus, the latter gives no consideration

to any benefit accrued from the use of debt against bankruptcy cost but look at debt as alternative

due to insufficient internally generated funds. Also the pecking order theory assumes leverage ratio

to be negatively related to firm performance. This relationship has been confirmed in many

empirical works (see Lemmon and Zender, 2008; Onaolapo and Kajola, 2010). On the other hand,

the former assumes leverage ratios are positively related to firm performance, which also has been

confirmed in many empirical studies (see Sola, 2010; Nosa and Ose, 2010). However, signaling

theory states that managers have incentives to use various tools to send signals to the market about

the difference that exist between them and weaker firms. One of the key tools to send these signals

is the use of debt. Employment of debt in financing decision shows that managers have better

expectations about the future performance whereas equity sends a bad news about the firm

performance in the future. Thus, most of the arguments of relevancy theories are held on risks and

returns inherent in employment of each financing mix available to the firm. Conventionally, the

primary aim of financial structure decisions via employment of equity and debt is to maximize the

market value of a firm at minimal overall cost of capital (Khrawish and Khraiwesh, 2008). Hence,

utilization of different levels of debt and equity in the firm’s financial structure is one of the firm-

specific strategies used by managers in the search for improved performance.

Page 17: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

4

Although, the assumptions of irrelevance theory is based on the perfect capital market, such as; no

taxes, rational investors, perfect competition, absence of bankruptcy costs and market efficiency.

This led to Modigliani and Miller (1958) argument that “in a world of sure returns, the distinction

between debt and equity funds reduces largely to one of the terminology”. Thus, whether a firm is

financed by debt or by equity, market value of any firm is independent of its financial structure.

But in the world of imperfect capital market that exists in reality, financial structure may be

relevant. The underlining argument of traditional theories of financial structure is underscored on

frictionless nature of MM theorem that holds the theory incomplete. Ross (1977) points “...if MM

theory is complete and thought to be correct, then capital structure is indeterminate or random in

actuality, and this a somewhat inhibiting basis on which to develop an explanation of financial

structure. One possible approach to the problem is to modify the MM theory to take account of the

structural features of the real world”. Ross (1977) stressed further that since interest payment on

debt are deductable in computing corporate income tax; the value of the firm should rise with the

substitution of debt for equity financing. Therefore, high profitability could be associated with high

target debt ratio, which may arise for a number of reasons such as potentially higher tax savings

from debt, lower probability of bankruptcy, and potentially higher overinvestment, and other

things equal (Hovakimian et al., 2004). The inherent unrealistic nature of MM theorem; and

subsequent work by Jensen and Meckling (1976) regarding the influence of financial structure on

firm performance due to agency costs of a firm and other factors has spawned numerous empirical

tests as highlighted earlier. Notwithstanding the importance of most of the underscored factors,

there is varied empirical evidence on the impact of financial structure on the performance of a firm

in Nigeria. Test of the agency theory typically regress measures of financial structure on firm

performance indicators and some control variables (Allen and Emilia, 2002). The researcher

therefore, will employ these measures on panel data regression models to examine the impact of

financial structure on the performance of Nigerian quoted firms using recent available data of

quoted firms to fill the research gap.

1.2 Statement of the Problem

The impact of financial structure decision on firm performance has been ambiguous due to

extensive arguments from diverse perceptions. The subsisting empirical studies to prove the impact

of debt and equity mix on firm performance in Nigeria is narrowed to capital structure measures

with established contradictory views inferred from the inconsistencies among their findings. Thus,

Page 18: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

5

the results and conclusions on the studies may be misleading. For instance, Adelegan (2007)

demonstrated negative insignificant relations between firm performance and leverage. While,

survey on the impact of capital structure on the firm performance by Onaolapo and Kajola (2010)

established that capital structure has a negative and significant impact on the firm performance.

Also, in studying capital structure and performance in Nigerian petroleum industry, Dare and Sola

(2010) documented positive significant relationship between leverage ratio and corporate

performance.

Nevertheless, financial structure measures (total debt ratio, long term debt ratio, and short term

debt ratio, among others) have a better chance to acquiesce unbiased result, because of different

empirical implications in regard to different types of debt instruments. However, in

underdeveloped debt market peculiar to Nigeria, most firms’ external debt finance is majorly short

term finance, imposing extra burdens at very exorbitant costs on the firms. For example, Titman

and Wessels (1988) contend that significant results are good reason for adoption of different

measures of leverage ratios because some of the theories of financial structure have different

implications for not adopting the narrow definition of leverage ratios. Similarly, it is interesting to

differentiate short- term debt, long- term debt and total debt effects since they have different risk

and return profiles (Zuraidah, et al., 2012). This disclosure raises an important research question

on the effectiveness of financial structure, in enhancing performance of quoted firms in Nigeria.

To fill this important knowledge gap, this study therefore sought to examine the impact of

financial structure on the performance of Nigeria quoted firms by employing various measures of

financial structure.

1.3 Objective of the Study

In line with the research problems, the study sought to examine the impact of financial structure on

firm performance, using data from Nigerian quoted firms. The specific objectives of this study are

as follows; to

i. Ascertain the impact of total debt ratio on the performance of quoted Nigerian firms.

ii. Determine how long term debt ratio is impacting on the performance of quoted Nigerian firms.

iii. Examine the impact of short term debt ratio on the performance of quoted Nigerian firms.

1.4 Research Questions

Based on the specific objectives as highlighted in the study, the researcher postulates the following

research questions:

i. To what extent does total debt ratio influence performance of quoted firms in Nigeria?

ii. How does long term debt ratio impact on performance of quoted firms in Nigeria?

iii. To what extent does short term debt ratio impact on performance of quoted firms in

Nigeria?

1.5 Research Hypotheses

In order to achieve the objectives as highlighted in the study, the following hypotheses were

formulated;

i. Total debt ratio does not have positive and significant impact on firm performance.

ii. Long term debt ratio does not positively and significantly impact on firm performance.

iii. Short term debt ratio does not have positive and significant impact on firm performance.

1.6 Scope of the Study

This research work covered Nigerian quoted firms that fall within non financial sectors

classification. Hence, financial sector such as commercial banks, merchant banks, insurance

companies, and other specialized financial institutions are excluded in the study. The justification

for this is that financial sectors are highly regulated; there are restrictions placed on them by the

regulatory authorities, which in turn influence their financial structure relatively to performance.

This study covers the period 2001-2010. The year 2001 was chosen as the base year because it

was the year universal banking was introduced in the banking sector. Since bond markets are

underdeveloped and inactive, commercial banks and other financial institutions play an important

role in providing loans to Nigerian firms. This period, 2001- 2010 also witnessed some significant

policy reviews. Notable among the policy are resuscitating of Domestic Debt Market in 2003;

1.7 Significance of the Study

Empirical investigation on the relevance and irrelevance of financial structure on firm value has

been carried out in different jurisdictions by prominent financial economist. Their findings so far

have been significantly relevant to both learning and development. As observed by the researcher,

most studies in Nigeria are majorly on the impact of capital structure on the firm performance with

narrow definition of financial structure. This study sought to fill the research vacuum in Nigeria by

exploring the impact of financial structure on the performance of Nigerian quoted firms.

Consistently, this study will make robust contribution on the literature “financial structure and firm

performance”. It will also expose firms financing pattern and its impact on the financial

performance. To be precise this study will have immense benefit to the followings;

Financial Analyst

The study will aid financial analyst to infer the nature of equity and debt position of the sampled

firms and also reveal the risk of interest bearing assets. In turn, may enable decision makers to

restrained unwholesome practices in financing pattern of most firms when the analyst can establish

the real class of firm’s assets.

Investors and Firms

Investors are not left out to benefit from this study, as this would enable them to ascertain risk

nature of their investment in sampled firms’ financial instruments. It will also give in-depth

knowledge to firms on the way to reduce the price of their floating assets relatively to inherent risk

of the assets, in turn lowering the volatility of their earnings.

Regulators

To regulators and other participants in the financial and real sector, it will provide some insight on

the need to enhance development in the sectors.

CHAPTER TWO

LITERATURE REVIEW

2.1.1 Concept of Financial Leverage

In this section we look at theoretical review of concept of financial structure. The body of

theoretical literature contends that leverage ratios are suitable quantitative measures of firms’

financial structure. Leverage ratio is a portion of firm assets financed with any type of fixed-charge

financing such as debt or leases. Thus, leverage is a tool if prudentially employed increase earnings

potential of the residual owners. Goldsmith and Lipsey (1963), contend that leverage ratio is a

measure of potential, rather than actual, capital gain. Therefore, leverage ratio suggest the effects

of possible changes in price-pointing out which groups might be vulnerable to, or favoured by,

price changes of various type. Leverage ratio indicates the firm’s risk exposure in meeting debt

service charges. A high leveraged firm faces a higher risk that its equity capital can be wiped out

when outcomes from its exposure to risky assets are unfavourable. Higher leverage magnifies

market risk as leverage firm may be forced to sell assets in order to reduce exposure under adverse

market conditions. Thus, firm that is heavily financed by debt offers creditors less protection in

the event of bankruptcy. For example, if a firm’s assets are financed with 75 percent debt, the

value of the assets when decline by only 25 percent, creditors’ funds are endangered. In contrast, if

only 25 percent of a firm’s assets are debt financed, assets value can drop by 75 percent before

jeopardizing the creditors’ funds.

On the other hand, leverage ratios also are of concern to owners of the firm because it influences

the rate of return they can expect to realize on their investment and the degree of risk involved.

Nwude (2003) postulate that higher leveraged firm is faced with greater fixed charge interest rate,

decrease in profit and cash flow is limited by financial leverage resulting to reduced dividends or

no dividends and, in turn fall in share price. This however, can increase the probability of default

in interest payments, thereby increasing the chances of corporate failure. Thus, the level of

leverage ratio employed by a firm is paramount to potential earnings of the firm.

However, measures of financial structure used in most empirical studies are debt ratio, debt equity

ratio, long term debt ratio, short term debt ratio, long term debt to market value equity, short term

debt to market value equity, convertible debt to market value equity, long term debt to book value

Page 26: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

13

equity, short term debt to book value equity, convertible debt to book value equity, times interest

earned ratio, fixed-charge coverage ratio (Titman and Wessels, 1988; Majumdar and Chhibber,

1999; Zeitun and Tian, 2007; Tze-Sam and Heng, 2011; Zambuto et al., 2011; Hatfield et al.,

1994; Onaolapo and Kajola, 2010; Baker and Wurgler, 2002; Staking and Babbel, 1995;

Schiantarelli and Sembenelli, 1997; Long and Malitz, 1985; Booth et al., 1999; Almazan et al.,

2007; Ju et al., 2004; Olatundum and Ademola, 2008; Kasozi and Ngwenya, 2010; and Muradoglu

and Sivaprasad, 2008; Khan, 2012; Azhagaiah and Gavoury, 2011) among others.

2.1.1.1 Total Debt Ratio

Total debt ratio measures the amount of a firm’s total assets that is financed with external debt.

This measure encompasses all short term liabilities and long-term liabilities. Nwude (2003)

contend that this measures portion of the firm’s assets that is financed by creditors. As the total

debt ratio increase, so do a firm’s fixed-interest charges, if the total debt ratio becomes too high,

the cash flow the firm generates during economic recessions may not be sufficient to meet interest

payments. In terms of its significance to a firm, theoretical literatures predict that debt is positively

correlated with level of investment. For example, long and Malitz (1985) found a significant

positive relationship between the rate of investment in fixed plant and equipment and level of

borrowing. The total debt ratio is measured by dividing total debt with the total assets of the firm.

This proxy variable remained most notable measure of leverage ratio of a firm as adopted in many

empirical studies (Zeitun and Tian, 2007; Onaolapo and Kajola, 2010; Tze-Sam and Heng, 2011;

Kasozi and Ngwenya, 2010; Baker and Wurgler, 2002; Ju et al., 2004; and Booth et al., 1999;

Khan, 2012; Azhagaiah and Gavoury, 2011).

Total Debt ratio = AssetsTotal

2.1.1.2 Debt Equity Ratio

Debt equity ratio is similar to the debt ratio and relates the amount of a firm’s debt financing to the

amount of equity financing. Actually, this measure of leverage ratio is not actually a new measure;

it is simply the debt ratio in a different format. Debt equity ratio is the quantitative measures of the

proportion of the total debt to residual owners’ equity (Nwude, 2003). Thus, it is an indicator of

company’s financial structure and whether the company is more reliant on borrowing (debt) or

Page 27: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

14

shareholders capital (equity) to fund assets and activities. Many empirical studies in different

jurisdictions have employed this measure of financial structure in their various studies (Zeitun and

Tian, 2007; Majumdar and Chhibber, 1999; Azhagaiah and Gavoury, 2011) among others.

Debt equity ratio = FundsrsShareholde

'

2.1.1.3 Long Term Debt Ratio

Although this measure is incorporated in the last two measures highlighted above, some analysts

generally use this measure because most interest costs are incurred on long-term borrowed funds,

and because long-term borrowing places multi-year, fixed financial obligations on a firm. Titman

and Wessels (1988) contend that significant results are good reason for employment of different

measures of leverage ratio because some of the theories of financial structure have different

implications for not combining them as aggregate “debt ratio”. Long term debt ratio is measured

by dividing long term debt with the total assets of the firm, and has been adopted in several

empirical studies (Titman and Wessels, 1988; Zeitun and Tian, 2007; Tze-Sam and Heng, 2011;

Long and Malitz, 1985; Booth et al., 1999).

Long term debt ratio = AssetsTotal

DebtTermLong

2.1.1.4 Short Term Debt Ratio

Short term debts are debt obligation that matured within one accounting year. This measure is very

appropriate to be included in the measures of leverage ratio due to implication it normally revealed

when there is occurrence of mismatch of funding by a firm. This may be one of the reasons that led

to adoption of different measures of leverage ratio rather than narrow measure of financial

structure by some scholars. Titman and Wessels (1988) contend that theories have different

empirical implications in regard to different types of debt instruments. Thus, mismatching funds is

a situation when long term investments are financed by short term debt rather than long term debt.

Apparently, the occurrence of this is prone to default as payment of interest and repayment of

principal may fall due when the proceeds (cash inflow) from the investment are not readily

available. The inability of the firm to repay the principal will expose it to the embarrassments

resulting from legal actions. This measure however, indicates the magnitude of current liabilities

Page 28: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

15

(obligations) to changes in the value of overall assets of a firm. Schinasi (2000) contends that

leverage is the magnification of the rate of return whether positive or negative on a position or

investment beyond the rate obtained by a direct investment of own funds in the market. The body

of theoretical literatures have argued that short term measure is a good measure of leverage ratio in

transition economy with less developed debt market where most firms’ external debt finance are

majorly commercial bank loans. Lucey and Zhang (2011) are of the view that market liberalization

at the country level decreases the use of long-term debt, and debt maturity shifts to short term.

Empirical investigation by Khan (2012) revealed that engineering sector firms in Pakistan are

largely dependent on short debt but debts are attached with strong covenants which affect the

performance of the firm. A good number of authors have employed this measure in their empirical

studies (Timan and Wessels, 1988; Zeitun and Tian, 2007; Long and Malitz, 1995; Khan, 2012)

among others. This is measured thus;

Short term debt = AssetsTotal

DebtTermShort

2.1.1.5 Times Interest Earned Ratio

Times interest earned ratio is one of the measures of leverage ratio that employs income statement

data to measure financial structure. This measure tells the financial analyst the extent to which the

firm’s current earnings are able to meet current interest payments. The earnings before interest and

tax of the firms are used because the firm makes interest payments out of operating income.

Theoretical literatures contend that when the times interest earned ratio falls below 1.0, the

continued viability of the firm is threatened because the failure to make interest payments when

due can lead to bankruptcy. Olatundum and Ademola (2008) point out that when times interest

earned declines; the firm is likely to face a high premium. The times interest earned ratio is

measures by dividing the earnings before interest and tax with the interest charges. This has

remained the used standard to ascertain the ability of the current earnings of the firm to offset its

current obligations. Olatundum and Ademola (2008) employed this measure in their empirical

study.

2.1.1.6 Fixed-Charge Coverage Ratio

Fixed-charge coverage ratio measures the number of times a firm is able to cover total fixed

charges, which include (in addition to interest payments) preferred dividend and payments required

under long term lease contracts. Firms in some time are require to make sinking fund payments on

bond issues, these are annual payments aimed at either retiring a portion of the bond obligation

each year or providing for the ultimate redemption of bonds at maturity. Under most sinking fund

provisions, the firm either may make these payments to the bondholders’ representative (the

trustee), who determines through a lottery process which of the outstanding bonds will be retired,

or deliver to the trustee the required number of bonds purchased by the firm in the open market.

Either way, the firm’s outstanding indebtedness is reduced.

In calculating the fixed-charge coverage ratio, an analyst must consider each of the firm’s

obligations on before-tax basis. However, because sinking fund payment and preferred stock

dividends are not tax deductible and therefore must be paid out of after-tax earnings, a

mathematical adjustment has been made. Nwude (2003) contend that this measure the extent to

which earnings may fall without causing problem to firm as regards the payment of interests and

other fixed charges. A high coverage ratio is preferred and suggests strength.

2.1.2 Concept of firm Performance

In this section, we look at concept of firm performance. The concept of performance in finance is a

controversial issue largely due to its multi-dimensional meanings. Santos and Brito (2012) posits

that the definition of firm performance and its measurement continues to challenge scholars due to

its complexity. This theoretical literature has spawned the interest of numerous studies.

Performance measures are either financial or organizational (Zeitun and Tian, 2007). Citing the

work of Chakravarthy (1986) and Hoffer and Sandberg (1987) by Zeitun and Tian (2007) point

that financial performance such as value maximization, maximizing profit on investment, and

maximizing residual owners equity are at the core of the firm’s effectiveness, while, operational

measures, such as growth in sales and growth in market share, essentially emphasizes wide range

of performance as they focus on the factors that specifically result to financial performance. There

are statutory requirements to provide information for performance of publicly traded companies by

the regulatory authorities. And also information asymmetries between management and other

contracting parties create a demand for an internally generated measure of firm performance to be

Page 30: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

17

reported over finite intervals. This however, provide source of information to investors and

creditors on the firm’s cash generating ability (Dechow, 1994). Financial statement is the

instrument that conveys information to the users of financial information. Market efficiency is

based on the theory of competition in which prices are competitively set and decisions reflect

available economic information (Dastgir and Velashani, 2008). Advocates of the “all-inclusive

concept” argue that comprehensive income statement provide better measures of firm

performance, than other summary income measures. On the other hand, those who advocate

“current operating performance” view of income argue that net income without inclusion of

extraordinary and non-recruiting items get better ability to reflect the firm’s cash flows (Dastgir

and Velashani, 2008).

The usefulness of a measure of performance may be affected by the objective of a firm and stock

market development relatively to the choice of performance measures (Zeitun and Tian, 2007).

Agency cost theory argues that self objectives (interests) of the company’s managers and

objectives of the firm (shareholders’ value maximization) are not perfectly aligned (Jensen and

Meckling, 1976). They opined that managerial share-ownership may reduce managerial incentives

to consume perquisites, expropriate shareholders’ wealth or to engage in other sub-optimal

activities and thus helps in aligning the interests of managers and shareholders and consequently

lowers agency costs and increase firm performance. Thus, the convergence of interest hypothesis

predicts that larger managerial ownership stakes should lead to better firm performance.

Depending on one’s view of performance measures, one can look at a firm and find it either

efficiently organized or not and that can lead to better performance. But there are established

theoretical literatures on the measures (indicators) of firm performance, although these have not

been adequately explored compare to other areas in finance. The most measure that proxies firm

performance are Return on Assets (ROA), Earnings per Share (EPS), profit margin, Return on

Equity (ROE) or Return on Investment (ROI), Tobin’s Q, P/E, etc (Zeitun and Tian, 2007, Booth

et al., 1999). The first four performance measures highlighted above merely represent accounting

measures of firm performance based on historical activities of the firm to generate financial ratios

from balance sheet and income statements. Several notable researchers have employed these

measures in their empirical studies (Zeitun and Tian, 2007; Booth et al., 1999; Tze-Sam and Heng,

2011; Onaolapo and Kajola, 2010; Kajola 2008; Zeitun, 2009; Skopljak and Luo, 2012; Khan,

2012; Azhagaiah and Gavoury, 2011). While, some body of theoretical literatures has established

Page 31: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

18

converse view on the measures of firm performance. They argued that rather than focusing on

accounting data that is merely historical, a firm performance is better obtain with the use of market

value. The market measures of firm performance are Tobin’s Q, price earnings ratio, and others.

Lang and Stulz (1994) contend that the use of Tobin’s q rather than performance over time, avoid

some of the problems of the earlier literature.

2.1.2.1 Return on Assets

Return on Assets (ROA) is measures of firm performance that reveals to the users of financial

statement how well a company uses its assets to generate income. A higher ROA denotes a higher

level of firm performance. A rising ROA, for instance, may initially appear good, but turn out be

unimpressive if compare with other companies in same line of activities or industrial average.

Hence, if company’s ROA is below industrial average the company is not utilizing its full capacity.

Booth et al. (1999) posits that this measure was used in their study because it was the only variable

that can be calculated across countries. They conclude that country comparisons of profitability are

therefore difficult. Among other authors that adopted this measure in their empirical studies are

Zeitun and Tian (2007), Zeitun (2009), Tze-Sam and Heng (2011), Onaolapo and Kajola (2010)

and Khan (2012). The ROA ratio may thus be more useful when compared to the risk free rate of

return to be rewarded for the additional risk involved. If a firm’s ROA is equal or even less than

the risk free rate, investors will be indifferent and better off just purchasing a bond with a

guaranteed yield.

2.1.2.2 Return on Equity

Return on equity is another measure of firm performance that shows how well a company has used

the capital from its shareholders to generate profits. Investors use ROE as a measure of how well a

company is using its money. Evidently, numerous empirical studies have employed this measure in

quest to observe the predicted relationship between financial structure and firm performance (Tze-

Sam and Heng, 2011; Zeitun and Tian, 2007; Onaolapo and Kajola, 2010; Kajola 2008; Zeitun,

2009; Skopljak and Luo, 2012; Khan, 2012).

2.1.2.3 Earnings per Share

Earnings per share is a ratio that measure earnings in relation to every share on issue. This is

measured by dividing the profit before interest and taxes with the outstanding number of shares of

the firm. This indicates how much each one share of the firm will earn from the yearly proceed.

The earnings for every share represent shareholders slice of the pie. As earnings go up over time,

the value of that piece of the firm becomes more valuable and this is why the price will be bid up.

Whilst there are not many truisms when it comes to share investment, one is that if earnings rise

consistently over the long term, then the share price will follow. Apparently, issue of shares that

increases the number of outstanding share dilutes the equity owners’ residual value. Tze-Sam and

Heng (2011) provide empirical investigation using EPS as a proxy for corporate performance to

establish its relationship with financial structure. The measure is derived thus;

2.1.2.5 Tobin’s Q

Tobin’s Q is the market value of assets (market value of equity plus market value of debt) divided

by estimated replacement cost (Brealey and Myers, 1996). Lang and Stulz (1994) assert that no

risk adjustment or normalization is required to compare Tobin’s Q across firms in contrast to

comparisons of stock return or accounting performance measures. Although, Tobin’s Q has been

employed in many empirical studies as a major indicator of firm performance but many

researchers have agreed it is noisy signal (Zeitun and Tian, 2007; Onaolapo and Kajola, 2010).

Similarly, Lang and Stulz (1994) posit that the problem with Tobin’s Q is that it reflects what the

market thinks, whether illusory or not. They suggest that to be able to adopt Tobin’s Q, financial

markets must assume to be efficient and firm’s market value is an unbiased estimate of the present

value of its cash flows. With this assumption, the ratio of the market value of the firm to the

replacement value of its assets is a measure of the contribution of the firms’ intangible assets to its

market value. Although, Tobin’s Q as market performance has been extensively used as a proxy

for firm performance but there is difficulties in getting required information relating to market

value of debt issued in most emerging economy like Nigeria, since these are not usually disclosed

in their financial statement (Kajola, 2008). He noted that most researchers used modified Tobin’s

Q that seems to be subjective, because the modification usually influences the outcome of the

study. Booth et al. (1999) using Tobin’s Q as a proxy for performance in their empirical study

found that market-to-book ratio is imperfectly correlated with Tobin’s Q and arrived at the

conclusion that the degree of correlation will differ across countries according to the accounting

principles adopted. Another empirical study by Khan (2012) revealed that Tobin’s Q as firm

performance is significantly negatively related to capital structure.

This measure can be derived as follow;

2.1.2.6 Price Earnings Ratio

The price to earnings ratio (P/E) measures the number of times the share price covers the earnings

per share. It is measured by taking firm’s current share price and dividing it with the earnings per

share (EPS). However, a firm’s P/E ratio should not be analyzed as a standalone number. It may be

interpreted in many ways depending on whether it is being compared with the firm’s historical

P/E, the industry P/E or even the market P/E. This measure as market performance measure was

used in empirical work of Zeitun and Tian (2007), which documented that the regression model

using price per share to earnings per share (P/E) is not significant using any measure of capital

structure. They gave the following reasons that have contributed to the insignificance of the

results; (i) that the share price does not reflect the actual situation of the firm, (ii) that most

investors still depend on the accounting measure of performance rather than the P/E measure due

to inactivity of the stock market, (iii) inclusion of default firms in the studies that have a low or

even negative P/E affects the validity of the P/E as a measure of performance.

2.1.3 Theories of Financial Structure

The firm’s mix of different securities is known as its financial structure (Brealey and Myers, 1996;

Dare and Olorunfeme, 2010). These theories have generated intense interest and criticism, thus

leading to different views on theoretical and empirical literature. Within these theories; the static

trade – off theory, agency cost theory, the pecking order theory and other theories are well

established (Brounen et al. 2005). According to Titman and Wessels (1988), a number of theories

have been proposed to explain the variation in debt ratio across firms. In the work of Myers

(1984), “the capital structure puzzle is tougher than the dividend one”. Modigliani and Miller

(1958) preposition assumed in a world of perfect capital market and no taxes, a firm financial

policy is irrelevant. Berens and Cuny (1995) submit that enormous academic effort has gone into

identifying the relevance of capital structure to a firm. As noted by Long and Malits (1985) and

Masulis (1980) later studies by Modigliani and Miller (1963), Baxer (1967), and Miller (1977)

introduced taxes and/or bankruptcy costs in an effort to explain capital structure.

Myers (1984) postulate that there is inadequate understanding of corporate financing behaviour,

and of how this behaviour affects security returns. The result of the enormous arguments in

theoretical literature can be adduced to have been attempted to reconcile Miller model with the

balancing theory of optimal capital structure (Bradley et al., 1984). According to Myers (1984),

“our theories don’t seem to explain actual financing behavior, and it seems presumptions to advise

firms on optimal capital structure when we are so far from explaining actual decisions”.

Nevertheless, the notable financial structure theories that explain the financial structure decision of

the firm includes; the Modigliani – Miller Theorems, Static Trade – off Theory, Dynamic Trade –

off Theory, Pecking Order theory, Agency Cost Theory, Ownership Structure Theory, Signaling

Hypothesis, Neutral Mutation Hypothesis, Market Timing Theory and other notable theories of

financial structure.

2.1.3.1 Modigliani – Miller Theorems

Modigliani and Miller theorems holds that when capital markets are perfect (frictionless and

perfectly competitive), no taxes and investment policy is fixed; financial structure is irrelevant to

firm value. That is, they postulate that when there are no taxes and perfect capital market, it makes

no difference whether the firm borrows or individual shareholders borrow. Therefore, the market

value of a firm is independent of its financial structure. The basic assumptions of the theorems

Page 35: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

22

were of perfect capital markets, no taxes, and no effect on management incentives (khadka, 2006;

Majumdar and Chhibber, 1999; Breadley and Myers 1996; Tze – Sam and Heng, 2011; Miller,

1988; Suhail and Wan Mahmood, 2008).

Modigliani and Miller proposition I posit that if capital markets are doing their job, firms cannot

increase value by tinkering with financial structure (Brealey and Myer, 1996). And proposition II

argued that weighted average cost of capital would remain the same no matter what combination of

financing mix the firm actually employed (Modigliani and Miller, 1958; Miller, 1988). Thus, these

propositions are held in the world of perfect capital market where value is invariance to financial

structure of a firm. In the work of Miller (1988),

our value – invariance proposition I was in a sense only the application of this

macroeconomic intuition to the microeconomics of corporate finance; and the

arbitrage proof we gave for our proposition I was just the counterpart at the

individual investor level of the consolidation of accounts, and the washing out of the

debt/equity ratios at the sectoral level. In fact, one blade of our arbitrage proof had

the arbitrager doing exactly that washing out. If levered firms were undervalued

relative to unlevered firms, our arbitrager was called on to “undo the leverage” by

buying an appropriate portion of both the levered firm’s debt and its shares. On a

consolidated basis, the interest paid by the firm conceals against the interest received

and the arbitrager thus owned a pure equity stream.

However, this theorem argued that with well functioning markets, no taxes and rational investors,

who can ‘undo’ the corporate financial structure by holding positive or negative amounts of debt,

the market value of a firm depends only on the income stream generated by its assets (Bailey,

2010). In the same vein, the future operating cash flows are unaffected by firm’s choice of

financial structure (Yany, 2009), and Suhaila and Wan Mahmoon (2008) documented that this

theory argues that “it does not matter how the size of the pie is sliced but what matters is the level

and risk of its future cash flows”. Accordingly, in a world with corporate taxation, tax deductible

interest payments subsidies the issuance of debt. Modigliani and Miller (1963) second seminal

paper argued that firm value is an increasing function of leverage due to the tax deductibility of

interest payments at the corporate level (Berens and Cuny, 1995 and Hull, 1999). Hence, in tax

environment interest expenses are tax deductible due to the income tax law, firms decreases the tax

23

liability and increases the after tax cash flows (Awan et al. 2011). The unrealistic proposition of

Modigliani and Miller theorems with the assumptions of frictionless markets, and zero bankruptcy

cost which contributed disagreement of Miller (1977) on the issue of optimal capital structure, and

thus, the impact of such costs depends on size of the firm relatively to the value of assets

transferred. In view of that, Miller (1977) demonstrated that variations in debt ratio also reflected

primarily the recurring movements of the economy, in expansions debt ratios tended to fall, partly

because the place of dividends behind earnings built up internally generated equity; and partly

because the ratio of equity to debt in sight financings tended to rise when the stock market was

flourishing. As with many aspect of the Modigliani – Miller theorems coupled with Miller model

that owners of corporation reap no gain, whatever from their use of tax-deductable debt rather than

equity capital when even personal income tax and corporate tax are applicable; there is room for

disagreement (Bailey, 2010). In the work of Berens and Cuny (1995), the “comer solution” implied

by Modigliani and Miller (1963) model is very much at odds with empirical observations of firm

behavior. Many researchers preceding Modigliani and Miller theorems have considered a variety

of wealth effects linked to leverage including bankruptcy and agency effects but disparity in

relation to the strength of these effects and tax shield advantage still prevail (Hull, 2007).

2.1.3.2 Static Trade – off Theory

Prominent authors have explicitly argued against irrelevancy theory. According to Myers (1984)

“static trade off framework is a situation in which a firm set a target – to – value ratio and

gradually moves towards it”. The theory viewed financial structure of a firm by adding various

imperfections including taxes, cost of financial distress and agency costs, but retains the

assumptions of market efficiency. And thus suggest that firm target leverage is driven by three

competing forces such as tax benefits, bankruptcy cost and agency costs (Nosa and Ose, 2010;

Huang and Ritter, 2004). In the static trade – off theory, the value of the levered and unlevered

firm is not the same (Awan et al., 2011). The authors pointed that debt financing firm can save the

amount of interest payments on the debts from tax purposes.

However, the theory holds that a firm borrows to the point where the marginal value of tax shields

on additional debt immediately offset the increase in the present value of bankruptcy cost (Mayer,

2001; Yang, 2009 and Baurer, 2004). This body of knowledge challenged the assumptions of

irrelevance theory with the argument that optimal capital structure of a firm is a trade – off

Page 37: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

24

between the benefit from tax advantage (tax shield) and cost of financial distress (bankruptcy

costs) from employing external capital (debt), holding the firm’s assets and investment plan

constant (Bas et al., 2009; Myers, 1984; Bradley et al., 1984; Zambuto et al., 2011; Sayilgan et al.

2006). Hence, value maximizing firms attain an optimal capital structure by offsetting the

corporate tax benefits of debt against the personal income tax, bankruptcy cost and agency cost

associated with debt. Masulis (1980) opines that unique optimal capital structure do exist in tax

environment whereas at margin, there is balance between corporate tax advantage and personal tax

disadvantage of holding debt. Firms target debt ratio is driven by tax shield, bankruptcy costs of

debt and agency cost (Suhaila and Wan Mahmood, 2008). Thus, most significant benefit of debt

financing is the tax shield from interest payments.

Nevertheless, static trade-off theory argues that firms balance beneficial tax shields with

bankruptcy costs when determining the appropriate leverage (Brounen et al., 2005). They reported

that firms that act along the lines of the static trade – off paradigm are expected to have a target

debt ratio. According to this theory, Bunn and Young (2004) states that in choosing financial

structure, firms seek to balance the benefits of debt against the potential costs of financial distress

that is made more likely at high debt levels. Similarly, this theory argues that there is an

equilibrium level of debt in which any further raise in leverage will increase the expected costs of

financial distress by more than the accrued benefit of that subsequent borrowing (Bunn and Young,

2004).

While, Ahmed et al. (2010) opines that firms set its target debt ratio in accordance to the nature

and requirements of business, and in turn moves gradually to achieve it. And firm’s performance

affects its target debt, which in turn is reflected in the firm’s choice of securities issued and its

observed debt ratios (Hovakimian et al., 2004). Shahjahanpour, et al. (2010) contributed that firm

maximize their values by maximizing the use of debt. Other authors like Manos and Ah-Hen

(2002) contend that each firm has an optimal debt ratio that maximizes firm’s value, although this

level varies between firms. Huany and Ritter (2004) report that static trade-off theory suggests that

firm should issue equity when their leverage is above the desired target leverage, issue debt when

their leverage is below the target or issue debt and equity proportionately to stay close to the target.

25

2.1.3.3 Dynamic Trade-off Theory

Extensive theoretical literature has established dynamic nature of firms’ capital structure. But

dynamic trade-off theory is not as popular as static trade-off theory leading to many authors

categorizing the two theories as one (trade-off theory). Although the distinction between these two

theories are not well established. Hull (1999) and Ju et al. (2004), postulate that dynamic trade-

off theory corresponds with traditional trade-off approach in the pursuit of an optimum capital

structure but not static. They assert that factors affecting financial structure are tax shields and

bankruptcy costs. This suggests that some managers make financial structure decisions with the

objective of maximizing the total value of the levered firm. Optimal capital structure is the point at

which the financing costs and the Weighted Average Cost of Capital (WACC) are minimized,

thereby maximizing returns (Onaolapo and Kajola, 2010 and Tz-Sam and Heng, 2011). In other

words, this theory argues that firms chose capital structure base on the attributes that determine the

costs and benefits associated with debt ratio, which can be maintain or revert to predetermine debt

to equity ratio that maximizes firm value and /or minimized risk of default (Kasozi and Ngwenga,

2010).

Thus, firm with different types of assets will have different bankruptcy and agency costs coupled

with optimal debt ratios. Berens and cuny (1995) argue that capital structure can be obtained by

moving to a dynamic multi-period setting. They assert that given set of interest payments over

time, a firm’s current debt ratio can vary with its debt maturity structure, reflecting different

default risks. This implies that there may be multiple optimal debt ratios even if the set of interest

payment is unique.

Bhamra et al. (2008) posit that firms optimally choose not only the amount of debt but also the

timing of refinancing in dynamic trade-off theory. Thus, optimal financial structure of a firm varies

over time implying an optimal range rather than static. Fisher et al. (1989) and Leland (1989)

argues that in dynamic trade-off theory firms let their leverage fluctuate overtime reflecting

accumulated earnings and losses and do not adjust it toward the target as long as the adjustment

costs exceed the value lost due to suboptimal capital structure in (Hovakimian et al. 2004). Hence,

firm’s rational decisions make target leverage ratio to be dynamic due to adjustment to hedge

against suboptimal financial structure. The dynamic trade-off theory implies that the optimal target

capital structure of firms adjusts over time and is a function of changing exogenous and

Page 39: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

26

endogenous factors (Getzmann et al., 2010). Another contribution by Hovakimian et al. (2004),

firms that follow a dynamic trade-off strategy will chose the amounts of new debt and equity that

the deviation from the target is induced by accumulation of earnings and losses. Thus, offsetting

the accrued benefits and losses lead to dynamic nature of financial structure, thereby results in the

debt ratio close to the target.

2.1.3.4 Pecking Order Theory

Traditional views of financial structure have taken different dimension with priority to internal

funding. According to Shahjahanpour et al. (2010) pecking order theory was first observed by

Donaldson (1961) and thereafter was supported by Myers (1984), working on agency theory of

Jensen and Meckling (1976), and also by Myers and Majluf (1984), working on information

asymmetry. In Myers (1984), contrast to the static trade-off theory with a competing popular story

based on a financing pecking order, firms prefer internal finance and if external finance is required,

firms issue less risk debt and equity as a last resort. This theory is looking at the least cost of

financing mix, as it argues that firms do not try to reach the “optimal” capital structure, as the

trade-off theory claims, because firms employ least resistance and least costly financing mix

(Kasozi and Ngwenya, 2010). Zambuto et al. (2011) report that this theory argues that information

asymmetry problem between insiders and outsider of a firm lead to increases in the cost of external

capital. Brounen et al. (2005) contends that the degree of asymmetric information determines the

relative costs of each source of finance. As they stressed further, firms that adopt this pecking

order of finance do not have a target debt ratio, because the ordering determines their choice of

issuance of new capital. Moreover, the more severe the asymmetric information, the more riskier

the investment for investors, invariably the higher the price of the security (Octavia and Brown,

2008). Hence, with the presence of asymmetric information, a firm is better financed by internally

generated funds than external funds. This was supported in the work of Hovakimian et al. (2004),

managers do not attempt to maintain a particular capital structure, rather financing decision are

driven by the costs of adverse selection that arise because of information asymmetry between

better – informed managers and less – informed investors. They further noted that because these

costs are incurred only when securities are issued by the firm and are lower for debt than for

equity, firm prefer internal financing and prefer debt to equity when external funds have to be

raise. For example, in internally generated funds, the firm will have more information about the

Page 40: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

27

firm than new equity holders who will expect a higher rate of return due to asymmetric

information (Abor, 2008).

Kim et al. (2006), and Afrasiabi and Ahmadinia (2011) explicitly stressed that a firm tends to draw

on firstly internal financing and later on external financing by issuing corporate bonds when there

is insufficient internally generated funds. Sundaram (2008) contends that managers may prefer

internal financing because it relieves them from the disciplining effects on the security markets. In

attempt to explain the observed corporate finance patterns this theory suggests that firms do not

issue stock and their choice is to hold large cash reserves and other forms of “financial slack”

(Chen, 2004).

In the same vein, pecking order theory argues that firm should follow specific hierarchy of assets

financing. Notably, internally generated funds from retained earnings should been employ first

then debt when internally equity are exhausted and external equity as last resort if need be (Kasozi

and Ngwenya, 2010; Afza and Hussain, 2011; and Ahmed et al., 2010). Eriotis (2007) and Abor

(2008) report that the theory argues that highly profitable firms that generate high retain earnings

are expected to use less debt capital than those that do not generate high earnings.

Pecking order theory of capital structure argues that the primary determinant of capital structure of

a firm is the problem of asymmetric information between firm insiders and outsiders (Agca and

Mozumdar, 2004). Firms’ managers are reluctant to issue equity when the firm is undervalued and

investors rely on managers’ actions as signals regarding the true value of the firm. Hence, issue of

equity by the firm is likely to be interpreted as a bad signal, which must be avoided by relying

primarily on internally generated equity (Manos and Ah-Hen, 2002). According to Dincergok and

Yalciner (2011), “pecking order theory states that there is no optimal capital structure since debt

ratio occurs as a result of cumulative external financing requirements”. Huang and Ritter (2004)

assert that optimistic entrepreneurs are not willing to issue external equity because they think their

stock is undervalued. Thus, pecking order theory expects equity issues to be rare.

2.1.3.5 Agency Cost Theory

Agency cost theory was first incorporated in financial structure argument in the work of Jenson

and Meckling (1976); this theory was incorporated in financial structure because of agency

relationship between the principal (shareholders) and agent (manager) when there is separation of

Page 41: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

28

ownership and control. This theoretical literature argues that agency costs arise because of interests

of the principal and agent resulting from personal utility maximization does not align (Kim, et al.,

2006 and Siddiqui and Shoaib, 2011). Eisenhardt (1989) asserts that agency theory is directed at

the ubiquitous agency relationship, in which one party (the principal) delegates work to another

(the agent), who performs that work. While, Berger and Patti (2002) posits that agency costs of

outside ownership equal the lost value from professional managers maximizing their own utility,

rather than the value of the firm due to separation of ownership and control. In the work of

Eisenhardt (1989), agency theory is concerned with resolving two problems that can occur in

agency relationships. The first is the agency problem that arises when (i) the desires or goals of the

principal and agent conflict (ii) it is difficult or expensive for the principal to verify what the

agents is actually doing. The problem here is that the principal cannot verify the agent has behaved

appropriately. The second is the problem of sharing that arises when the principal and agent have

different attitudes toward risk. The problem here is that the principal and the agent may prefer

different actions because of the different risk preferences.

Similarly, Barcley et al. (2006) noted that conflicting of interest between managers and

shareholders can take a variety of forms. In their model, managers receive private benefits from

investment, which relatively increase with the projects’ NPV and apparently optimal for manager

to invest. Therefore, agency cost discretion depends on the allocation of control rights within the

firm. Eisenhardt (1989) contend that the focus of the theory is on determining the most efficient

contract governing the principal-agent relationship given assumptions about (eg, self-interest,

bounded rationality, risk aversion), organization (eg. Goal conflict among members), and

information (eg, information is a commodity which can be purchased). The domain of agency

theory is relationships that mirror the basic agency structure of a principal and an agent who are

engaged in cooperative behavior, but have differing goals and differing attitudes toward risk. The

theory advocate that when the contract between the principal and agent is outcome based, the agent

is more likely to behave in the interests of the principal and also when the principal has

information to verify agent behaviour, the agent is more likely to behave in the interests of the

principal. Thus the focus of the principal-agent literature is on determining the optimal contract

behaviour versus outcome between the principal and the agent. That is the trade-off between; the

cost of measuring behaviour and the cost of measuring outcomes and transferring risk to the agent

(Eisenhardt, 1989).

Page 42: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

29

Nevertheless, agency theory is most relevant in situations in which contracting problems are

difficult. The choice of financial structure may help mitigate these agency costs. High leverage

ratio reduces the agency costs of outside equity and increases firm value by constraining or

encouraging managers to act more in the interests of shareholders (Berger and Patti, 2002).

Moreover, the given incentives to the firm will benefit shareholders at the expense of debt-holders.

Thus, debt-holders need to restrict and monitor the firm’s behaviour. Onwumere et al. (2011)

contend that the use of debt finance which is linked to assets of the firm create a problem for the

firm because management may not want to run the risk of having conflicts with debt holders.

Hence, costly monitoring devices of contractual covenants are incorporated into debt agreements

to protect the debt-holders, it should increase the cost of capital offered to the firm. And also,

Heland and Pyle (1977) noted that firms with riskier returns will have lower leverage ratio even

when there are no bankruptcy costs.

In addition, Masulis (1980) posits that when manager own less stake in a firm, agency costs

increase relatively to optimal monitoring of managerial decisions and the level of perquisite

consumption by manage. He opined that agency cost model predicts financial structure of a firm

affects management incentives to make particular firm related decisions. Almazan and Molina

(2004) stressed that for agency conflict to shapes a firm’s financial structure will depend on the

manager’s attributes and on the firm’s ability to reduce managerial influence. Long and Malitz

(1985) opine, “firm’s unobservable growth opportunities reduce the effectiveness of bond

covenants, the only way in which owners of a firm with a high proportion of intangible investment

opportunities can control the agency cost of debt is by limiting the amount of risk debt

outstanding”. In the spirit of Fama and French (1998), profitable firms with strong growth

opportunities and thus high market value can avoid agency problems by choose lower leverage.

Thus, high leverage increases agency problem, firm needs to balance the cost and benefit of debt

because negative information in debt about profitability overwhelms any tax (or other) benefits of

debt.

In the work of Suhaila and Wan Mahmood (2008) and Dincergok and Yalciner (2011), agency cost

arises due to conflict of interest between shareholders and managers, or between shareholders and

bondholders. Brounen et al. (2005) and Octavia and Brown (2008) postulate that agency problem

between shareholders and bondholder arise due to asset substitution, in which shareholders prefer

high risk projects, because they can fully benefit from high earnings, while bondholders that have a

Page 43: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

30

fixed claim prefer low risk projects. The adjustment of leverage ratio to attain optimal financial

structure may lead to high agency cost if not rationally employed. As documented, the optimal

financial structure decision has to do with balancing the trade-off between the benefit of debt and

agency costs arising from mitigating the agency cost of managerial discretion against the agency

cost of debt arising from “asset substitution effect” (Octavia and Brown, 2008 and Shahjahanpour

et al. 2010). Also high leverage ratio increases the bankruptcy cost and agency cost of the firm as

well rises, and it is through this argument that agency costs can be incorporated into the financial

structure decision (Kim et al., 2006).

Manos and Ah-Hen (2002) pointed that agency consideration assume debt is valuable in reducing

the agency costs of equity but at the same time debt is costly as it increase the agency cost of debt.

While Ahmed et al. (2010), report that shareholders of a firm incur agency cost in attempt to

discourage self interest of the managers by means of monitoring and control actions. Eriotis (2007)

pointed out that managers of firms typically act as agents of the principal (owners). The principal

hire the agents and give them the power to manage the firm for the owners’ benefit. Hence,

manager is mainly interested in accomplishing their own targets which may differ from the

maximization of the firm value which is the maximization of the owners’ benefit. Finally, firms are

expected to set their financial structure in such a way the potential conflicts of interest between

managers, shareholders and debt holders are minimized (Sayilgan et al., 2006).

2.1.3.6 Signalling Hypothesis

The last two theories in the previous sections gave consideration to the information the policy

decision of the firm may convey to the market. This section also incorporates this information

dissemination and inference of the outsider. Signalling hypothesis argues that different levels of

information between insiders and outsiders are such that insider behaviour passes information

about firm value to outsiders (Hull, 1999). He posits that this theory predicts that a change in

firm’s financing mix contains information about stock value. In the work of Ross (1977) and

Leland and Pyle (1977), managers (insider) possess the true information of firm’s returns, but

investors (outsiders) do not. Molinari et al. (2009) noted that problems of asymmetric information

might raise the cost of external finance and lead to credit rationing. In this case, the ability to

generate cash flow becomes important for financing investment. Suhaili and Wan Mahmoon

(2008) and Brounen et al. (2005) shed light that if managers decide to issue more debt, outsiders

Page 44: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

31

interpret it as a signal of high future cash flows and management confidence towards firm’s future

prospect. Suhaili and Wan Mahmood (2008) contributed further that issue of new equity is signal

of management lack of confidence towards firm’s future prospect. Due to asymmetric information

investor tend to undervalue new equity issuance, which increase the attractiveness of debt relative

to equity finance (Bunn and Young, 2004). Awan et al. (2011) posit that issuance of equity instead

of debt financing for new projects, investors will interpret the signal negatively. Therefore, since

managers have superior information about the firm than investors, they might issue equity when it

is overpriced.

The trade-off between the benefits of signalling and bankruptcy costs implies that a firm chooses

debt ratio at certain proportion to be better off. That is a good firm need large debt to act as an

incentive compatible signal and bad firm need not (Bauer, 2004). Ross (1977), signalling models

suggest that inside managers use leverage to signal growth prospect to outside investors who

believe in these signals due to information asymmetry. Managers of most corporations make

financing decision with dubious motive to secure their job and decisive investors and owners of the

firm. If a firm is undervalued due to information asymmetry problems, the insiders of the firm can

stimulate the share prices to rise by increasing debt, which in turn triggers investors believe of

future prospect (Dincergok and Yalciner, 2011). Eriotis (2007) posits that firms avoid issuing

undervalued stock unless the value transfer from “old” to new shareholders are more than offset by

the net present value of the growth opportunity. Theoretical literature by Sayilgan et al. (2006)

supported that managers of a firm maximizes his incentive return by employing finance mix that

trades off the current value of the signal given to the market against the incentive consequences on

that return.

2.1.3.7 Neutral Mutation Hypothesis

Neutral mutation hypothesis is not well established in literature when compared with other

extensively investigated theories in this field of study. This argues that sometime firm employs

financing decisions that cannot be predicted, and also doesn’t have any significant effect on the

firm value. Therefore, firm has undefined pattern or habit that can influence the value of a firm.

Myers (1984) posits that firm manager who identifies these habits and adopts them to predict

financing behavior would not be explaining anything important (meaningful). Thus, neutral

mutation ideal is important as a warning. Myers (1984) noted reasons for not embracing neutral

Page 45: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

32

mutation as a strict null hypothesis makes the game of research too tough to play, if a firm can

identify costs that explain firms’ financing behaviour that can yield optimal returns. And also the

information effect of the financing choice of the firm. In the same vein, outside investors are

interested in the firm’s financing decisions, because they result to changes in the stock price when

the decisions are made public. According to Myers (1984), “…as a one-on-one competition of the

static trade-off and pecking order stories. If neither story explains actual behaviour, the neutral

mutations story will be there faithfully waiting”. Hence, this hypothesis essentially explains

undefined financing pattern in a firm financing decisions.

2.1.3.8 The Market Timing Theory

Market timing theory argues that firms issues equity when their market performance is high

(Hovakimian et al., 2004). Thus, if conditions on markets are unfavorable firms rarely go to the

market, there is possibility to delay investments. This is supported by a body of knowledge that

asserts that firm delay issuing securities due to expectation of growth opportunities. Apparently,

firms that mostly issue securities at peak (growth) period is expected to obtain this funds at low

price resulting to high expected rate of return. Hence, financial structure only depends on equity

market returns and conditions on the bond markets and a target financial structure does not exist

(Getzmann et al., 2010).

Afrasiabi and Ahmadinia (2011) posit that market timing theory of financial structure argues that

issuance of equity by the firm are timed, in such a way that when the stock prices are perceived to

be overvalued, they in turn issue new equity and buy back when they are undervalued. They

further stressed that fluctuations in stock prices affect firm’s capital structure. And also the theory

assumes economic agents (managers) to be rational and irrational. Managers issue equity when

they believe their cost is irrationally low and repurchase equity when they believe their cost is

irrationally high. Thus, manager does not predict stock returns but they believe they can time the

market.

Huang and Ritter, (2004) supported the view of rational and irrational manager with argument that

firms prefer external equity when the cost of equity is low, and prefer debt otherwise. The theory

believes that windows of opportunity exists as long as the relative cost of equity varies over time

for either rational or irrational reasons, and has important implications for financial structures

Page 46: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

33

choices. Therefore, the condition in the market determines the position of the firm to be either

equity finance or debt finance, which invariably influences the value of the firm.

2.1.4 Determinants of financial Structure

There are many determinants of financial structure of a firm which if not properly taken into

consideration in financing decisions of a firm may hinder its performance. These factors can be

separated in two broad categories; internal or company characteristics and external determinants.

On one hand, company specific determinant comprises internal factors that influence the leverage

ratio of a firm such as tangibility, growth rate, current profitability, firm’s financial risk, firm’s

size, firm’s age, non tax shield, asset turnover, etc (see Titman and Wessels, 1988; Ahmed, et al.,

2010; Barel, 2004; Bauer, 2004; Abor, 2008) among others. On the other hand, external

determinants comprise exogenous factors that is uncontrollable by the firm such as prevailing

interest rate, tax rates, exchange rate, volatility and liquidity of capital markets, etc (Graham and

Harvey, 2002). Although, Barney (2001) asserts that success of a firm significantly depends on the

strategic resources under its control. Our major concern here is narrowed to internal factors, which

are firm specific factors that affect the financial structure and firm performance of a firm. The

followings have been identified as the theoretical determinants of financial structure of a firm

(Baral, 2004, Bauer, 2004, Abor, 2008, Gaud et al. 2003 and Shahjahanpour et al. 2010).

� Size of the firm

The size of a firm determines the level of leverage at any point in time. Bauer (2004) asserts that

the effect of size on leverage is ambiguous. Large firms are more diversified and less vulnerable to

bankruptcy. The size of a firm is likely to have positive relationship with leverage (Baral, 2004 and

Bauer, 2004). Abor (2008) contributed to the literature with the view that debt of large firms are

likely to be redeemed than the debt of smaller firms, reducing the agency costs associated with the

debt of larger firms. Thus, smaller firms are less diversified and more vulnerable to bankruptcy,

therefore there is a need for low debt ratio. The bankruptcy cost theory suggests the lower debt

level, the lower bankruptcy cost, and the higher debt level, the higher bankruptcy cost resulting

from higher volatile cash flows, (Baral, 2004). Converse view was documented in the work of

Jensen and Meckling (1976), the larger the firm becomes, the larger are the total agency costs due

Page 47: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

34

to likelihood that the monitoring function is inherently more difficult and expensive in a large

organization compare to smaller organization.

� Growth opportunities

According to Baral (2004), “the agency cost theory and pecking order theory explains the

contradicting relation between growth and capital”. Firms with high growth opportunities

apparently, should be finance with equity source, which in turn reduces agency costs between

shareholders and managers. Agency cost theory suggests that equity controlled firms have the

motive to undertake assets substitution investment thereby investing sub-optimally to expropriate

wealth from the bondholders (Baral, 2004). Thus, firms with high growth opportunities not

financed by equity effectively transfers dividend from stock holders to debt holders. There is

contrary idea on the relationship between growth opportunities and financial leverage. The use of

debt is limited in firms with growth opportunities as in the case of bankruptcy, the value of growth

opportunities will be close to zero (Gaud et al., 2003). Some scholars argued that growth

opportunities are positively related to leverage, while others contend an inverse relationship.

Several empirical studies have documented an inverse and verse relationship between growth and

leverage ratio (see for example, Abor, 2008; Bauer, 2004; Baral, 2004; Khrawish and Khraiwesh,

2008). Bauer (2004) posits negative relationship between growth opportunities and leverage. On

the other hand, pecking order theory argues that growth firms with robust financing needs will

issue securities (external financing through debt issue) (Gaud et al., 2003 and Baral, 2004). Thus,

pecking order theory predicts positive relationship between growth opportunities and leverage.

� Profitability

This determinant of financial structure is in twofold. The first is on the side of static trade-off

theory that predicts positive relationship between profitability and leverage. This essentially

implies that the higher the profitability of a firm, the higher the debt capacity in relation to less

risky to the debt holders (Baral, 2004). While, the second fold is the pecking order theory that

predict inverse relationship, all things being equal (Myers, 1984).

The trade-off theory argues that more profitable firms should have higher debt ratio because of tax

benefit from the use of debt finance. Jensen and Meckling (1976) on their paper work contributed

immensely with the explicitly expression that one factor which encourage the use of debt is the tax

Page 48: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

35

subsidy on interest payments. The gains from the tax subsidy will accrue entirely to the equity and

will provide an incentive to utilize debt to an end where the marginal wealth benefits of the tax

subsidy are presently equal to the marginal wealth effects of the agency costs associated with the

use of debt. The argument from free cash-flow theory predicted positive relations with the

suggestion that high profitable firms should use more debt as a disciplinary tool to managers, to

induce them to pay out cash instead of spending money on inefficient projects (Bauer, 2004).

According to pecking order theory firm prefer internal finance, adapt their target dividend payout

ratio, which are adjustable to the extent of valuable investment opportunities and if unpredictable

fluctuations in profitability and investment opportunities occurs that internally generated funds are

exhausted, firms issue the safest security first and external equity as a last resort (Myers, 1984).

Thus, profitable firms with sufficient earnings will rely more on internally generated funds as

oppose to external debt and equity source of finance.

� Tax

Trade-off theory suggests that a firm with a higher tax rate should employ more debt financing mix

due to more income from tax shield (Bauer, 2004). There are enormous studies on the tax effect

and financing decisions of a firm (Miller, 1977, Myers, 1984, Graham, 1999). Therefore, change in

the firms’ tax bracket has a significant implication on its financing decisions.

Myers (1984), given significant differences in effective marginal tax rate,

and given that the static trade-off theory works, we would expected to find a

strong tax effect in any cross-sectional test, regardless of whose theory of

debt and taxes you believe.

Therefore, marginal rate of company’s tax influences the financing behaviour of such company.

Gaud et al. (2003) contend that due to tax benefits accruing from the use of tax, companies have an

incentive to employ debt to their financing need. The author stressed further that firms with large

non-debt tax shields have a lower incentive to use debt as accord by tax shield. Firms with more

taxes is expected to have high tax shields benefit that accrued from debt, thus a positive

relationship between effective tax and leverage is predictable (Shahjahanpour et al., 2010).

Page 49: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

36

� Business risk

Leverage ratio of a firm indicates firm’s risk exposure and its’ vulnerability to bankruptcy. A firm

that is highly levered apparently has high volatile net profit. Thus, leverage influences the rate of

return for an investment relatively to magnitude of unsystematic risk. Gaud et al. (2003) suggest

that firms with high business risk can lower the volatility of the net profit by reducing the level of

debt, which in turn will decrease bankruptcy risk and probability of expected benefit from the tax

shield will increase as well. The more volatile the firm’s earning stream, the greater the chance of

the firm defaulting and being exposed to bankruptcy costs (Abor, 2008). The advocate of agency

cost theory and bankruptcy theory predict significant relationship between financial structure and

business risk. The bankruptcy cost theory posits that the higher the volatility of firm’s stream of

cash inflows, the greater its’ chance of business failure relative to the degree of bankruptcy costs

(Baral, 2004). He contends further that relatively, as the probability of bankruptcy increases, the

agency problems related to debt become more severe similar to predictions underscore by other

scholars.

� Tangibility

Tangibility as determinant of financial structure is essentially concern with the type of assets

owned by the firm. Titman and Wessels (1988) contend that most capital structure theories argue

that the type of assets owned by a firm in some way affects its financing decision. Apparently,

these assets are used to secure debt issued by the firm and the value relatively to leverage ratio

determines the risk exposure of the investors. Bauer (2004) opines that the higher collateral value

of firm’s assets, the greater their ability to issues secured debt, which in turn lowers the risk of the

bondholders and increases the value of the assets in the case of bankruptcy. Thus, tangibility also

determines the risk of loan contract relatively to interest rate. That is, firm that has high tangible

assets which can be pledge to secure debt resulting to low default risk invariably induce low

interest rate and in turn lead to high leverage since the firm can borrow at low cost (Bradley et al.,

1984). Gaud et al. (2003) assert that tangible assets of firms in contrast to intangible assets have a

greater value in the case of bankruptcy and they are less subject to asymmetries. Cost associated

with adverse selection and moral hazard risks are reduced when the firm pledges tangible assets as

collateral (Abor, 2008, Gaud et al., 2003). However, firms with tangible assets that have greater

liquidation value relatively have easier access to external finance at lower cost, consequently

Page 50: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

37

leading to higher debt ratio (Abor, 2008). Thus, tangibility resulting to greater liquidation value is

positive related to leverage.

� Payout ratio

Payout ratio is one of the determinants of financial structure predicted by pecking order theory to

have positive relationship with leverage. Baral (2004) viewed that bankruptcy costs theory pleads

for adverse relationship between dividend payout ratio and leverage. Low dividend payout means

increase in the internally generated funds (retain earnings) and low exposure to financial distress.

Firms however, avoid using external funding means whenever the internal funds are available and

firms adjust their dividend payout ratio in consideration to their investment opportunities and

profitability (Shahjahanpour et al., 2010). As highlighted in pecking order theory firms prefer

internally generated funds than external funding reflecting low income distribution as dividend

(low payout ratio) and high retention ratio (high retain earnings), consequently low leverage ratio

of the firm.

2.2 Empirical Review

2.2.1 Financial Structure and Firm Performance

The unrealistic assumptions and vague empirical evidence of the Modigliani and Miller value-

invariance propositions and paradox indifference in cost of financing propositions II contributed to

numerous empirical investigations on capital structure and firm performance. Adelegan (2007)

found negative insignificant relations between values and leverage in pooled regression and

negative significant relations between debt and change in leverage in the small-size sample. The

finding is in line with Miller (1977) hypothesis that debt has no net tax benefit because personal

income taxes on interest affect the corporate tax savings. Examining capital structure and financial

performance of selected business companies in Colombo Stock Exchange, Paratheepkanth (2011)

confirmed insignificant negative relationship between capital structure and financial performance.

Another study based on empirical research on the effects of capital structure change on security

prices in USA by Masulis (1980) revealed that stock price changes have the same qualitative

relationship to announced leverage changes regardless of the direction of the change.

Majumdar and Chhibber (1999) investigating the relationship between capital structure and

performance for a sample of Indian firms, found significant and inverse relationship between debt

Page 51: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

38

equity ratio and corporate performance. Introducing several control variables in the study; Size,

Diversity, Advertising and Liquidity were found to been positively related to performance. While,

age, group, time and excise are negatively and significantly related to performance. However, the

inverse relationship between capital structure and firm performance as concluded may be due to

high cost of borrowing (rate of interest) in Indian capital market as well highly-leverage firm are

considerably less profitable than firms with a greater level of equity in their capital structure. Many

empirical studies using panel data regression estimation confirmed the inverse relations between

capital structure and firm performance (Schiantarelli and Sembenelli, 1997; Ebaid, 2009;

Adelegan, 2007; Zeitun and Tian, 2007; Cheng and Tzeng, 2011; and Onaolapo and Kajola, 2010;

Uremadu and Efobi, 2012; Azhagaiah and Gavoury, 2011; Mubashar et al., 2012).

Schiantarelli and Sembenelli (1997) empirically investigate the determinants and consequences of

the maturity structure of debt using data from a panel of UK and Italian firms. Including leverage

as a regressor to control for the impact of general financial pressure on productivity, evidence from

Italy shows negative and significant effect of leverage on firms’ performance. This means that

being under financial pressure does not lead to greater productivity. The result is not in line with

theoretical framework that is embedded on the role of financial pressure inducing managers to

undertake prudent decisions. Accordingly, they pointed that a high leverage may also weaken the

incentive to pursue efficiency, since borrowers, relative stake in the firm is smaller. However, the

impact of capital structure choice on firm performance based on a sample of non-financial

Egyptian listed firms from 1997-2005 by Ebaid (2009), using OLS multiple regression analysis,

revealed that capital structure measured by total debt to total assets and short term debt to total

assets impacts negatively on the firm performance measure by return on asset. On the other hand,

the study showed that capital structure measured by short term debt to total assets, long term debt

to total assets and total debt to total assets has no significant impact on firm’s performance

measured by return on equity and gross profit margin. Ebaid (2009) thereby conclude that capital

structure choice in general terms, has weak or no influence on the financial performance of listed

firms in Egypt.

Investigating the impact of capital structure on performance of Nigerian firm by Onaolapo and

Kajola (2010), debt ratio as a measure for capital structure was found to be negatively and

significantly related to two measures of firm performance (ROA and ROE). Studying the impact

of capital structure and liquidity on corporate returns in Nigeria by Uremadu and Efobi (2012), the

Page 52: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

39

study covered 10 manufacturing firms for period of 2002-2006. Using OLS regression estimate the

study established that high corporate income tax regimes combined with high inflation rates in

Nigerian business environment may not have enabled firms to optimize use of long term debts to

maximize profitability. The authors posit that increasing proportion of long term debts compared

to equity in the capital structure mix of Nigeria firms will contribute to increases in corporate

profits of companies. Also it was noted that increasing proportion of both short term debts and

long term debts on the overall liability of the firm reduces corporate profitability. The study

however, showed that log linear analysis of the value of long term debts assumed a negative but

the result were found inconsistent with the prediction made earlier. Hence, the implication of this

according to the authors is that either inadequate long term debts were mobilized by corporate

entities in Nigeria or serious distortions may have existed in the economic and financial systems of

the economy within the period covered.

Cheng and Tzeng (2011) studying leverage and efficiency of Taiwan Manufacturing firms from

2000-2009, employed technical efficiency instead of financial accounting measure and found that

leverage is negatively related to technical efficiency in all industries but more significantly in

Textile industry. Co-alignment among corporate strategy, financial structure and firm performance

in non-financial sector of Pakistan by Mubashar et al. (2012), using panel data methodology

revealed that financial structure measured by debt ratio proved to have significantly negative

impact on firm performance measured by return on asset and free cash flow per share. The authors

concluded that their study has proved the implication of pecking order theory by Pakistani non-

financial listed firms. Thus, suggesting that if firms want to increase their profitability then, they

should avoid debt, if they are in need then, they have to sacrifice their profitability thereby

equipping themselves for future consequences. Also using pooled ordinary least square regression

to study the relationship between capital decisions and firm performance, Khan (2012) applied 36

engineering Sector firms in Pakistani listed on the Karachi Stock Exchange (KSE) during the

period 2003-2009. He however observed that financial leveraged measured by short term debt to

total assets (STDTA) and total debt to total assets (TDTA) has a significantly negative relationship

with the firm performance measured by return on assets (ROA), gross profit margin (GM) and

Tobin’s Q. But the relationship between financial leverage and firm performance measured by the

return on equity (ROE) is negatively insignificant. The author further concludes that firms in the

Page 53: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

40

engineering sector of Pakistan are largely dependent on short term debt but debts are attached with

strong covenants which affect the performance of the firm.

Similarly, cross sectional regression analysis by Fama and French (1998) revealed that firm value

is negatively related to leverage and concludes that this inverse relationship is attributed to the

negative correlations of leverage with the proxies for profitability. And also, impact of financial

structure on firm’s performance in chemical sector of Pakistan by Amjed (2008) revealed

significant negative relationship between leverage and firms’ performance. Specifically, the results

revealed that long term debt of the industry is significantly low in turn portray significant negative

relationship with the financial performance of the firm.

On the other head, Tze-San and Heng (2011), Margaritis and Psillaki (2009), Nosa and Ose (2010),

Adeyemi and Oboh (2011), Dare and Sola (2010), Chowdury and Chowdhury (2010), Abu-Rub

(2012), and Skoljak and Luo (2012) provide empirical support for the body of theoretical literature

that argue capital structure to be positively related to firm performance. Margaritis and Psillaki

(2009) studied capital structure, equity ownership and firm performance using a sample of French

firms from low and high growth industries, which documented that higher leverage ratio, is

associated with improved efficiency over the entire range of observed data. Tze-San and Heng

(2011) using Malaysian construction sector from 2005 - 2008 with sample of 49 construction

companies confirmed this dividing the company into big, medium and small sizes based on the

paid up capital. The results specifically indicate that corporate performances of large companies

are partly affected by their changes in capital structure. The results of medium and small

companies are also partly affected by the changes in capital structure but the portion is lesser

compare to large companies.

Consistent with prior empirical evidence, Abu-Rub (2012) investigated capital structure and firm

performance using panel data procedure for a sample of 28 listed companies in Palestinian Stock

Exchange over the period of 2006 – 2010. The study showed that return on equity, return on assets,

earnings per share, market value of equity to the book value of equity and Tobin’s Q as a measure

of firm performance is positively related to capital structure measured by short term debt, long

term debt and total debt to total assets, and total debt to total equity at very significant level. Also,

Studying the impact of capital structure on firm’s value, Chowdury and Chowdhury (2010)

analysed 77 firms from different dominant sectors of Bangladesh capital market. The study

Page 54: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

41

revealed significant positive relationship between capital structure and firm value. Thus, it was

observed that a change in current ratio, operating leverage, EPS, dividend payout ratio or share

capital of a firm may increase its value in the market. The study however, suggests that

maximizing the wealth of shareholders requires a perfect combination of debt and equity.

Similarly, Dare and Sola (2010) employing panel data regression analysis of Nigerian Petroleum

Industry found significant positive relationship between leverage ratio and corporate performance

and suggest the need for petroleum industry in Nigeria to improve on their leverage ratio.

Adopting different measures such as growth opportunity, non-debt tax shield, tangibility,

profitability, and earnings volatility as proxies for leverage ratios, Nosa and Ose (2010) in their

study showed a significant positive relation with corporate performance except volatility. But

empirical investigation by several authors adopted these measures as control variables not as

proxies for leverage ratios (for example, see; Majumdar and Chhibber, 1999; Zeitun and Tian,

2007; and Onaolapo and Kajola, 2010; Cheng and Tzeng, 2011; and Adeyemi and Oboh, 2011).

Adeyemi and Oboh (2011) incorporating control variables in their study found positive relation

with control variables and firm performance as well as leverage ratio with market value. Skopljak

and Luo (2012) studying capital structure and firm performance in financial sector using explicitly

Australian data, found that increase in leverage ratio lead to increase in bank performance at

relatively low levels of leverage while at relatively high levels of leverage, the effect of financial

distress exceeds the beneficial effects of debt. Previous empirical study by Pratomo and Ismail

(2007) using Malaysia data to survey Islamic Bank performance and capital structure confirmed

the result that the more levered bank is better than the less or unlevered bank as regard to profit

efficiency.

Also in conformity with relevance theory, Zuraidah et al. (2012) studying capital structure effect

on performance of Malaysian firms employed ROA and ROE as performance measure, while short

term debt (STD), long term debt (LTD) and total debt (TD) as capital structures. The study

covering 58 firms from 2005 to 2010 showed that only STD and TD have significant relationship

with ROA while ROE has significant relationship on each debt level. However, model estimation

for lagged variables revealed that non of lagged values for STD, LTD and TD has significant

relationship with performance. Likewise Mojtaba and Shahoo (2011) examined the relationship

between financial structure and firms performance in firms traded on the Tehran stock exchange,

the study revealed significant relationship between financial structure and ROA as performance

Page 55: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

42

measure, but insignificant relationship was found between financial structure and ROE as

performance measure.

2.2.2 Financial Structure and Tax Effect

DeAngelo and Masulis (1980) cite Miller and Modigliani (1966) study of 63 electric utility firms

that documented a significant positive relationship between market values of the firm and the debt

tax shield. They conclude that the evidence may justifiably be criticized because of limitations in

the statistical methodology as well as the inherent difficulties involved in controlling for cross-

sectional differences in firms’ underlying asset values and biases associated with studying a

regulated industry. DeAngelo and Masulis (1980) observation on offer announcement effects on

preferred stock revealed that the corporate tax effect exceeds the bankruptcy cost and distribution

effects for these preferred stock issues. Another study by Long and Malits (1985) shows positive

relationship between; tax shield and long term debt, and capital expenditures and financial

leverage. Given that a firm must seek an outside source of funds, it choice between debt and equity

will depend in part on the magnitude of potential agency costs of debt. They conclude that the

findings provide direct empirical evidence that the moral hazard problem is important and that

investment and financing decisions are not independent. Similarly, Graham (1996) paper titled

“debt and the marginal tax rate”, tests whether the incremental use of debt is positively related to

simulated firm-specific marginal tax rates that account for net operating losses, investment tax

using annual data from more than 10,000 firms from 1980-1992. The result showed that positive

influence of Marginal Tax Rate (MTR) on debt policy is robust to purely cross-sectional analysis,

although there is a noticeable deterioration in the relation between debt policy and Marginal Tax

Rate (MTR) in 1986. The outcome as the author reported may be possibly due to the tax Reform

Act 1986. He further concludes that the effects of Marginal Tax Rate (MTR) are generally

significant when data are aggregated over three or 12 years. Hence, the study provides robust

empirical evidence in favour of relationship between leverage decisions and tax status. Adelegan

(2007) researched on effect of taxes on business financing decisions and firm value in Nigeria and

found negative relationship between debt and value, which is consistent with information

asymmetry model of Myers and Majluf (1984) and Myers (1984). Thus, this is as a result of

information conveyed by firm’s financing decision. This model predicts that a change in a firm’s

financing decisions contains information about stock value. Investors know that firms tend to issue

risky securities when they are overvalued. Consequently, firms follows pecking order theory as a

result that new issues meet with price discounts.

In addition, Barclay et al. (2006) studied on the debt capacity of growth options and showed robust

empirical support for the prediction that the relation between growth options and book leverage

ratios should be negative. The result is consistent with previous empirical evidence (Faulkender

and Peterson, 2006). In attempt to study the effect of firm and industry debt ratios on market value,

Hatfield et al. (1994) found that relationship between a firm’s debt level and that of its industry

does not appear to be of concern to the market. The result shows that high debt firms has

significant negative market reactions for several intervals, but the difference between this high and

the low debt firm was not statistically significant. The authors inferred that the market does not

consider industry average for leverage as discriminators of firms’ financial leverage. Sen and Oruc

(2008) testing pecking order theory in Istanbul Stock Exchange Market from 1993-2007, find a

significant negative relationship between total asset, profitability, current ratio, the ratio of fixed

assets to total assets and leverage ratio. Their result support the view that, although there is tax

shield benefit from the use of debt but information asymmetry problem and bankruptcy costs may

outweigh this benefit and in turn deteriorate net present value of the firm. The methodologies

adopted by some of the studies reviewed in this chapter, will be employ in this study, to enable the

researcher critically investigate the impact of capital structure on firm performance.

2.3 Summary of Review of Related Literature

Financial structure is the combination of debt and equity capital by a firm on the course of funding

its corporate investment. The relevance and irrelevance of financial structure theory in explaining

variation of firm performance has been ambiguous due to extensive arguments from diverse

perception. Within the established theories of financial structure; the static trade-off theory, agency

cost theory, pecking order theory and other theories are well established (Brounen et al., 2005). In

the spirit of Myers (1984), “the capital structure puzzle is tougher than the dividend one”.

Modigliani and Miller theorems argued that with well functioning markets, no taxes and rational

investors, can ‘undo’ the corporate financial structure by holding positive or negative amounts of

debt, the market value of a firm depends only on the income stream generated by its assets (Bailey,

2010). Thus market value of a firm is independent of its financial structure. Incorporating tax in

their subsequent studies, the theory argued that firm value is an increasing function of leverage due

Page 57: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

44

to the tax deductibility of interest payments at the corporate level (Berens and Cuny, 1995 and

Hull, 1999). Invariably owners of corporation reap no gain, whatever from their use of tax-

deductable debt rather than equity capital when even personal income tax and corporate tax is

applicable (Bailey, 2010). Theoretical and empirical body of knowledge emanating from MM

theorems have considered a variant of wealth effects linked to leverage including bankruptcy and

agency effects but disagreement about the strength of these effects and tax shield advantage still

prevail (Hull, 2007).

Ross (1977) points that the irrelevance theory assumes the existence of symmetric information

with the suggestion that there will be no systematic relationship between the financing decision

and the value of the firm. But the conventional view assumes the existence of asymmetric

information where financing decision affects market value (Leland and Pyle, 1977). The authors

assumed statistical positive but not causal relationship between debt and value of “seemingly

similar” projects. In the same spirit, Jensen and Meckling (1976) argue that the net effect of the

increased use of external debt increases the total agency costs and increases optimal fraction of

external debt obtained from the sale of external equity. Desai et al. (2003) posit that the use of

debt rather than equity finance grows as the corporate tax rates rises. Therefore, high corporate tax

rates may lead to greater corporate indebtedness owing to firm’s need to enjoy debt tax shield

benefit. Similar argument was demonstrated in the work of Miller (1977) that the year to year

variation in debt ratio reflected primarily the cyclical movement of the economy.

However, trade-off theory established that optimal capital structure of a firm is a trade-off

between the benefit from tax advantage (tax shield) and cost of financial distress (bankruptcy

costs) from employing external capital (debt), holding the firm’s assets and investment plan

constant (Myers, 1984, Bradley et al., 1984, Zambuto et al., 2011). Hence, value maximizing firms

attain an optimal capital structure by offsetting the corporate tax benefits of debt against the

personal income, bankruptcy cost and agency cost associated with debt. While, firms that adopt

pecking order of finance do not have a target debt ratio, because the ordering determines their

choice of issuance of new capital. The degree of asymmetric information determines the relative

costs of each source of finance. The more severe the asymmetric information, the more riskier the

investment for investors, invariably the higher the price of the security (Octavia and Brown, 2008).

With the presence of asymmetric information a firm is better finance by internally generated funds

than external funds.

45

On the other hand, agency theory argues that the choice of financial structure may help mitigate

agency costs that arise as a result of separation of ownership and control. High leverage ratio

reduces the agency costs of outside equity and increases firm value by constraining or encouraging

managers to act more in the interests of shareholders (Berger and Patti, 2002). But the given

incentive to the firm will benefit shareholders at the expense of debt-holders. The adjustment of

leverage ratio to attain incremental value may lead to high agency cost if not rationally employed.

The market timing of financial structure decision as argued by market timing theory is another

rational for value maximization. Accordingly, a firm issue equity when the stock prices are

perceived to be overvalued and buy back when there are undervalued. Financial structure decisions

are determine by the fluctuations in the stock price.

There are many determinants of financial structure which can be categorically classifies as internal

and external determinants. Macroeconomic indicators such as tax policy of government, inflation

rate, capital market condition, among others are the major external factors that affect the financial

structure of a firm. The internal determinants which are major focused of a firm and specific

factors (firm characteristics) that affect the financial structure and firm performance of a firm

relatively. Thus internal factors are size of the firm, growth opportunities, profitability, business

risk, tangibility and payout ratio. Financial liberalization results in the development of capital

market and overall financial system, however, corporate investment depends mostly on output and

profits than macroeconomic and other policy variables (Mahmud et al., 2009). Thus, firm’s

performance in most cases reflect its’ corporate decisions in developed and most emerging

financial system. Stock market development leads to substitution of equity for debt, the effect

would be a decline in the debt-equity ratio (Bokpin and Isshap, 2008). According to Afrasiabi and

Ahmadina (2011) “an issue that is strictly connected with the choice of financing sources is risk

and return”. Therefore, in financial structure decisions there is need to ensure that marginal benefit

accrued from employment of external capital outweigh bankruptcy cost and agency costs resulting

from the use of this funds. A proper balancing of debt and equity is imperative in order to ensure a

trade-off between risk and return to the shareholders (Khadka, 2006). Thus, this financing decision

in turn leads to value maximization.

Majumdar and Chhibber (1999) attribute high cost of borrowing (rate of interest) to negative and

significant relationship between capital structure and firm performance. Highly levered firms are

considerably less profitable than firms with a greater level of equity in their capital structure. In

Page 59: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

46

addition, high leverage may also weaken the incentive to pursue efficiency, since borrowers,

relative stake in the firm is small. This is consistent with the observation of Khan (2012) that

financial leverage has a significantly negative relationship with the firm performance. Engineering

sector studied by the author is observed to be largely dependent on short term debt but debts are

attached with strong covenants which affect the performance of the firm. Fama and French (1998)

also confirmed that firm value is negatively related to leverage which is attributed to the negative

correlations of leverage with the proxies for profitability.

Empirical body of knowledge on the other hand have showed that higher leverage ratios are

associated with improved efficiency (firm performance) over the entire range of observed data

(Margaritis and Psillaki, 2009; Tze-San and Heng, 2011; Dare and Sola, 2010, Nosa and Ose, 2010

and Adeyemi and Oboh, 2011). Skopljak and Luo (2012) established that improvement in firm

performance induce by leverage ratios is attributed to low levels of leverage while, at a relatively

high levels of leverage, the effect of financial distress exceeds the beneficial effects of debt. Given

that a firm must seek an outside source of funds, it choice between debt and equity will depend in

part on the magnitude of potential agency costs of debt (Long and Malitz, 1995). The test of

pecking order theory by Sen and Oruc (2008), confirmed the existence of tax shield benefit from

the use of debt but information asymmetry problem and bankruptcy costs may outweigh this

benefit and in turn deteriorate net present value of the firm.

CHAPTER THREE

RESEARCH METHODOLOGY

3.1 Research Design

Research design essentially concerns the specification of procedures, which connect theoretical

predictions to the inquiry strategies and empirical material collection methods to address research

problem. In other words, research design involves a format on systematic method of data

gathering, procedures and method of analyzing necessary data (Onwumere, 2005 and Ibe, 2003).

Thus, it is the master plan upon which the statement of problems is addressed. The nature of the

problem under investigation and the corresponding objectives however, determine the approach

and method to be employed.

The study being an empirical analysis of the impact of financial structure on firm performance,

secondary data were used. Ex-post facto research design was employed in obtaining, analyzing and

interpreting the relevant data for hypotheses testing. The rationale for the variety is that ex-post

facto research design allows the researcher the opportunity of observing one or more variables

over a period of time (Uzoagulu, 1998). Specifically, panel data were adopted in data analysis.

3.2 Nature and Source of Data

The secondary data employed in this study have been adopted in previous studies with regard to

financial structure and firms’ performance, and other related studies. There are several studies

performed in the area and the researcher has gathered information from these studies to enhance

this research work and to proffer solution to the research problem. The dataset employed in this

study were generated from Nigeria Stock Exchange factbook and annual reports and statement of

accounts of quoted firms in Nigeria. Firm annual statements and reports are deemed to be reliable

because they are statutorily required to be audited by a recognized auditing firm before publication

(CAMA, section 331-335) in Onwumere et al. (2011). The items of interest in the financial

statement are assets, liabilities, shareholders’ funds, and earnings for each financial year.

3.3 Population and Sample Size

Data for statistical analysis in this study were gathered from financial statement of sampled firms.

Owen and Jones (1977) contend that most statistical information is obtained by examining the

Page 69: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

56

sample which is truly representative of the population. These financial statements as expected from

the quoted firms are prepared and published in compliance with the accounting practice, which

include balance sheet and income statement of selected firms for the period of 2001-2012. The

dataset contains detailed financial information about each firm for each financial year. Sampled

firms were selected based on availability of data for the period and also financial sector firms are

excluded from the study. The researcher put many factors into consideration in the selection of the

sample firms. Such factors as highlighted by the researcher includes: firms that were listed in NSE

before the year of inception of the study, firms that change their financial accounting year-end

within the period of the study were excluded in the sample, firms that ceased operation at any point

during the period of the study were also be excluded, and as well as firms that had problems with

NSE and Securities and Exchange Commission (SEC) within the period under review. These

criteria were adapted in order to guide against data omission and ensure uniformity in the

presentation. Apparently, the selection of 51 firms was randomly sampled thereby ensuring that

most sectors of the industrial classification according to NSE are well represented.

3.4 Description of Research Variables

The variables used in this study are largely adopted from existing literature, in line with the

research problem and research objectives. The difference and similarities for the measurement of

financial structure and performance ratios were compared among the literature. Thus, dependent

and explanatory variables of the study have been determined according to the approach used by the

previous studies and how far data will be available for measurement purposes. Chen (2004) posits

that book value is used for the calculation of variables whenever applicable due to the fact that

only about 30% of the shares issued are tradable and there are extraordinary capital gains resulting

from secondary share trading. Miller (1977) contends that book value measures might give better

insight to corporate capital structure objectives than market value measures of leverage, which is

highly sensitive to changes in the level of stock prices. Consequently, the study employed only

book value measures of financial structure and firm performance. They are explained below as

follows:

3.4.1 Dependent Variable

Firm performance as the dependent variable of the study has different measures. According to

Ujunwa (2012) unbiased performance measurement is necessary for both strategic and diagnostic

Page 70: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

57

purposes. This study employed Return on Assets (ROA) as firm performance measure. Wahla et

al. (2012) revealed that firm’s market value is based not on its investment projects only but other

factors such as dividend policy, its governance/control and ownership structure which also add

value to the firms. However Tobin’s Q as a market performance measure was not considered. The

market value of debt, which is required in the measurement of Tobin’s Q is not readily provided in

the annual reports and statement of accounts of the selected firms. In order to ease this problem

many scholars employed modified form of Tobin’s Q, which are considered to be subjective and in

turn may influence the outcome of the study (Kajola, 2008). Zeitun and Tian (2007) pointed that;

as agreed by many researchers; Tobin’s Q as a market performance measure is a noisy signal and

not a good performance measure due to its limitations. Performance is either financial or

organizational. Zeitun and Tian (2007) citing Chakravarthy (1986) and Hoffer and Sandberg

(1987), financial performance which involve maximizing profit on assets and maximizing

shareholders’ wealth shows the firm’s effectiveness. While operational performance measures such

as growth in sales and market share provides a broad definition of performance as they focus on

the factors that ultimately lead to financial performance. According to Onaolapo and Kajola (2010)

and Zeitun and Tian (2007) ROA and ROE are the most commonly measures of firm performance.

3.4.1.1 Return on Asset (ROA)

Return on Asset (ROA) as accounting measure of performance is derived by dividing profit before

interest and tax with total assets of the company.

That is, ROA = AssetTotal

TaxandInterestBeforeofitPr

This proxy variable has been employed by many researchers as performance indicator (Ujunwa,

2012; Zeitun and Tian, 2007; Onaolapo and Kajola, 2010; Tze-Sam and Heng, 2011; Azhagaiah

and Gavoury, 2011, Zeitun , 2009, and Khan, 2012). Ujunwa (2012) and Onaolapo and Kajola

(2010) posits that ROA can be viewed as a measure of management efficiency in utilizing all the

assets under its control, which ultimately belong to shareholders irrespective of its source of

financing. This is a widely accepted measure of financial performance. We predict that ROA is

positively and significantly related to financial structure.

58

3.4.2 Independent Variables

Explanatory variables of the study are financial structure. This is portion of firm’s asset financed

by any type of fixed charge such as loan facilities, overdraft facilities, lease, etc. The management

of financial structure measures the degree to which firms are employing financial leverage and, as

such are of interest to creditors and owners alike, as argued by many scholars to invariably

influence firm’s value (Brealey and Myers, 1996). Both long and short-term creditors are

concerned with the proportion of leverage a firm employs, because it indicates the firm’s risk

exposure in meeting debt service charges (that is interest and principal repayment). A firm that is

heavily financed by debt offers creditors less protection in the event of bankruptcy. And also the

expected indirect and direct bankruptcy costs offset the other benefits from leverage. This view has

been confirmed by bankruptcy cost theory. There are several types of financial structure, but we

adopted three measures of financial structure. These are Total Debt Ratio (TDR), Long Term Debt

Ratio (LTDR) and Short Term Debt Ratio (STDR). As highlighted earlier, these measures were

based on book values of the firm. These measures are used based on two reasons which may be

highlighted as such: the payment of debt depending upon the book value of the loans and not on

the market value of debt. Also short term debt ratio is adopted because the financial structure of

firm in developing countries like Nigeria is primarily based on the short-term debt as compared to

the long term debt (Booth et al., 1999 and Awan et al., 2011).

3.4.2.1 Total Debt Ratio (TDR)

We adopted this variable from many scholars, it is measured as the ratio of total debt to total

assets (Kasozi and Ngwenya, 2010; Onaolapo and Kajola, 2010; Zeitun and Tian, 2007; Tze-Sam

and Heng, 2011; Awan et al., 2011; Baral, 2004; Bauer, 2004; Chen,2004; Gaud et al., 2003;

Khrawish and Khraiwesh, 2010; Khan, 2012; Azhagaiah and Gavoury, 2011).

That is; Total Debt Ratio = AssetsTotal

DebtTotal

This constitutes overall (aggregate) fixed-charge external capital employed by the firm to finance

its assets. Khrawish and Khraiwesh (2010) point that total debt ratio demonstrates the relationship

between total liabilities and total assets. It measures the proportion of a firm’s total assets that is

financed with creditors’ funds. As used here, the term debt encompasses all short-term liabilities

Page 72: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

59

and long-term liabilities. Some scholars prefer to use a narrower definition of debt considering

only interest-charging liabilities such a long-term debt or bonds, notes payable, and lines of credit.

3.4.2.2 Long Term Debt Ratio (LTDR)

Long term debt ratio as accounting (book value) measures the long term debt employed by the

firm. That is, an obligation having a maturity more than one year from the date it was issued. It is

measured as the ratio of long term debt to total assets.

That is; LTDR = AssetsTotal

DebtTermLong

The adoption of this proxy variable as a measure of financial structure has been applied by many

researchers (Chen, 2004; Timan and Wessels, 1988; Zeitun and Tian, 2007, Tze-Sam and Heng,

2011, Long and Malitz, 1985).

Hence, it has been noted that LTDR is a good measures of leverage ratio in developing countries

like Nigeria due to fund miss-match constrained by limited long term debt.

3.4.2.3 Short Term Debt Ratio (STDR)

Short term debt constitutes short term liabilities accrued to the firm. This is debt obligation of the

firm payable within one year. Short term debt ratio is measured as short term debt divided by total

assets.

That is; STDR = AssetsTotal

DebtTermShort

This measure of leverage ratio has been employed by numerous researchers such as Titman and

Wessels (1988), Zeitun and Tian (2007), Long and Malitz (1995), and Khan (2012).

Apparently, it has been noted as a good measure of financial structure in developing countries like

Nigeria where the proportion of this ratio constitutes mostly entire amount of the firm’s total debt

ratio. Lucey and Zhang (2011) asserts that in emerging market firms invariably obtain additional

debt finance owing to credit market integration, but primarily at short maturities. They stressed

further that the main reason for high proportion of short debt is that the weak financial and legal

Page 73: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

60

institutions in developing countries will force creditors to use short term debt to monitor and

discipline borrowers’ behaviour.

3.4.3 Control Variables

Control variables are factors that influence firms’ performance in one way or other. Majumdar and

Chhibber (1999), Zeitun and Tian (2007), Onaolapo and Kajola (2010), and Cheng and Tzeng

(2011) contend that there are a number of factors which impact on firm performance. Majumdar

and Chhibber (1999) stressed further that these factors may be firm-related, industry related or

related to aspects of institutional environment and have to be controlled. Due to the scope of this

study, the interest of the researcher is narrowed down to firm related factors, as the endogenous

factors, most policy makers of the firm can control as intrinsic factors which impact on

performance. Barney (2001) contends that success of a firm significantly depends on the strategic

resources under its control.

3.4.3.1 Size of a Firm

Several authors have suggested that performance of a firm is related to firm size. Zeitun and Tian

(2007), Majumdar and Chhibber (1999), Cheng and Tzeng (2011), Onaolapo and Kajola (2010),

Zeitun (2009), Pratomo and Ismail (2007), and Khan (2012) provide empirical evidence that the

size of a firm appear to determine a larger proportion of firms’ performance. Titman and Wessels

(1988) asserts that relatively large firms tend to be more diversified and less prone to bankruptcy.

This supports the arguments that large firms should be more highly leveraged. The size of a firm

determines economies of scale enjoyed by the firm. Larger firms that have a greater variety of

capabilities and can utilize the high leverage ratio efficiently with relative positive returns.

Conversely, larger size, if not efficiently utilized leads to negative returns. Titman and Wessels

(1988) opines that the cost of issuing debt and equity securities is related to firm size. Apparently,

small firms pay high cost to finance their investment needs than large firms. The size of a firm is

measured by natural logarithm of total assets (Zeitun and Tian, 2007, Onaolapo and Kajola, 2010)

and alternative measures of firm’s size are the natural logarithm of sales (Titman and Wessels,

1988; Majumdar and Chhibber, 1999; Zeitun and Tian, 2007 and Zeitun, 2009 ) and quit rates

(Titman and Wessels, 1988). Zeitun (2009) posits that logarithm of total sales has lower

explanatory power than total assets. This study will employ natural logarithm of total assets as a

Page 74: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

61

measure of firm size. The introduction of the proxy variable SIZE as an indicator of firm size is

expected to be positively related to firm performance.

3.4.3.2 Age of a Firm

Different authors have considered the age of a firm as an important determinant of firm’s

performance. Thus, the introduction of the control variable AGE is measured as the log of number

of years since inception to the date of observation. Majumdar and Chhibber (1999), and Onaolapo

and Kajola (2010) citing the work of Stinchcombe (1965) contends that older firms can acquire

experience based economies and mitigate the liabilities of newness. Durand and Coeurderoy

(2001) studying age, order of entry, strategic orientation, and organizational performance found

that a first-mover advantage in terms of organizational performance. In the same vein, Hajipour

and Gholamzadeh (2010) studying the effects of market entry strategy dimensions on the

performance with a sample of 118 manufacturing firms found that order of entry and product

positioning affect performance. They stressed further that pioneers gain advantages in terms of

stronger competitive position and higher customer satisfaction, which in turn do increase

profitability. Prominent authors in their empirical study have employed this measure as control

variable in the study of this nature and similar studies (for example, Majumdar and Chhibber,

1999; Zeitun, 2009 and Onaolapo and Kajola, 2010). The researcher predicts firm’s age to be

positively related to the firm’s performance.

3.4.4 Random Variables (Stochastic)

As highlighted earlier, there are other control variables that impact on the performance of the firm.

Stochastic variables are those variables that can also affect on firm’s performance. Koutsoyiannis

(1977) asserts that random variable in a correctly specified model, absorbs primarily stochastic

variations in the dependent variable produced by omitted variables in the equation and possibly

errors of measurement. These variables may be firm’s related factors (endogenous) and

institutional environment related factors. The latter factors are exogenous factors that cannot be

controlled by the firm. Koutsoyiannis (1977) pointed out that the values of the disturbance variable

are independent of the values of the regressors. In this study the random variables are firm’s

Diversification, Financial Openness, prevailing interest rate, rate of inflation, Foreign Ownership,

Firm’s Coverage and Excise and Imports duties.

62

3.5 Technique for Analysis

To obtain the observed values on the expectation of the impact of financial structure on firm

performance, panel data surveyed over a ten year period was employed. Panel data structure allows

us to take into account the unobservable and constant heterogeneity, that is, the specific features of

each quoted firm. The researcher employed pooled Ordinary Least Square (OLS), Fixed Effects

and Random Effects regression models to test the various hypotheses. Pooled OLS regression

technique is popular in financial studies owing to its ease of application and precision in prediction

(Alma, 2011). In addition, OLS method has been employed in a wide range of economic

relationships with fairly satisfactory results (Koutsoyiannis, 1977). Citing the work of Gaur and

Gaur (2006), Ujunwa (2012) stressed that fixed effects and random effects models will aid to

observe variations among cross-sectional units simultaneously with variations within individual

units over time. It assumes that variables are strictly time disparity or time invariant. This

undermines an exploration of the effect of slow changing within individual firms’ factors. Hence,

the rational for adopting Fixed Effects and Random Effects models estimator as additional test is to

enable the researcher control time contrast and time invariant variables, and thereby control for the

effect of the unobserved heterogeneity in the dataset. Ujunwa (2012) opines that coefficient of

estimations are reliable when regression parameters do not change over time and do not differ

between various cross-sectional units. Therefore, when the regression estimation differ widely

between the two models (Fixed and Random Effects models), the adoption of Hausman test will be

essential. Panel data over the period from 2001-2010 is used and in line with notable literature,

such as the work of Majumdar and Chhibber (1999), Zeitun and Tian (2007), and Onaolapo and

Kajola (2010), firm’s performance measure was regressed on each of the variants of financial

structure and other control variables holding other factors that may affect firm’s performance not

included in the equation constant. These analytical techniques will enable the researcher attain

justifiable and robust results.

DATA PRESENTATION AND ANALYSIS

4.1 Data Presentation

The data presented below are those deemed necessary for the analysis of the various objectives

formulated in the study. The financial structure indicators used in the analysis were delineated into

total debt ratio, long term debt ratio and short term debt ratio, while firm performance measure

employed in the analysis is return on asset. The aggregate ratios of the dataset from the sample

firms obtained for analysis purpose are show in the tables below.

The summary of aggregate values of research variables of the sample firms as defined over a ten

years period are presented in table 4.1.1 above. While figure 4.1.1below represents the graphs of

the trend of the variables. The graphs allow simultaneous examination of the employed data, while

clearly displaying the behaviour of the sample firms’ overtime as a reflection of quoted firms. A

cursory look at the graph revealed that the variables fluctuated over the period covered, ROA over

the period of study revealed remarkable fluctuations. The trend is apparently attributable to change

in financial structure of the selected companies and other significant government policies and

changes in macro-economic variables (Izedonmi and Abdullahi, 2011). The highest aggregate ratio

recorded in 2001 could be attributed to dividend of socio-political stability occasioned by the

inception of democracy in 1999. This has also brought about more advancement in technology and

68

other technical knowledge which in turn enhanced performance of the firms (World Bank, 2002).

Similarly, the steep downward and upward fluctuation for ROA revealed in fig. 4.1 is attributed to

internal and external characteristics of the firms (Barney, 2001). While, between 2005 and 2007

recorded a significant slope in the graph pointing to reforms in financial and real sectors of the

economy.

Furthermore, a glance at the graph shows that sample firms aggregate TDR over the period

exhibited steep upward and downward movement. It can be deduced that the above effects is an

indication of underdeveloped nature of debt market where major proportion of total debt ratio is

made of short term debt ratio that are redeemable within a short duration (Mubashar, et al., 2012).

Thus induce regular payment of debt (principal and interest) to avoid liquidation effects. There was

an occasional hike in the TDR in 2002 but preceded immediately by drop in 2003 and 2004, which

later revealed persistent upward movement in the subsequent year because of landmark reforms

across banking, insurance and pension sectors. However, TDR as at 2006-2008 indicated

downward movement. The rational for the downward movement is attributed to growth in

Nigerian Stock Market brought about by remarkable policies in financial sector more especially

bank consolidation in 2005 and 2007 transformation in Nigerian Capital Market (Iganiga, 2010).

Hence 2005/2007 recapitalizing banking and insurance companies encouraged companies in the

real sectors to approach the stock market, which encouraged investment in equity market leading

to high market capitalization and liquidity resulting to high turnover ratio (Ayadi and Adegbite,

2008). In 2007 Standard & Poor’s (S&P) described the Nigeria equity market as the fastest

growing in the emerging markets universe. Increase in capitalization of the Stock Exchange was

significant in the year. Thus, it was recorded that capital based of the consolidated banks led to

growth in stock market activities (Adegbaju and Olokoyo, 2008). On the other hand, upward slope

in TDR as at 2009 is attributed to global financial crisis that crippled economic activities thereby

stimulating companies’ leverage ratio to ensure sustainability. However, the tempo dropped

tremendously in the subsequent years owing to numerous policies introduced by regulatory bodies

to relieve the effect of financial meltdown (Nwankwo, 2011, Sanusi, 2011). Apparently, there was

improvement in overall macroeconomic environment and socio-political stability manifesting in

enhanced corporate governance, high market liquidity (arising from increased portfolio and foreign

direct investment) and increased attractiveness of investment opportunities in Nigeria (Otch, 2010,

Sanusi, 2011).

69

Long Term Debt Ratio (LTDR) over the period of study shows a persistent upward movement

confirming a gradual growth in capital market activities. This is evident in table 4.1.1 and figure

4.1.1c. The reason for this could be attributed to regulation that mandated increases in capital and

the subsequent voluntary capital sourcing by banks and insurance companies (Iganiga, 2010).

Occasional drop were only observed in 2006 and 2008 as well as 2012. While in conformity with

enhancement in capital market activities as noted earlier, short term debt ratio (STDR) exhibited

downward movement. This change is attributed to the growing efficiency of market operators, a

growing investment culture in the country, as well as encouraging economic environment being

nurtured by the democratic government (World Bank, 2002). Table 4.1 and figure 4.1d reveals

that little upward fluctuation in 2005 and 2007 were recorded in STDR, while downward

movement were recorded in other subsequent years. This is attributed to gradual development in

debt market brought about by market deregulation and market determined pricing as well as other

macroeconomic policy such as commencement of T3 trading cycle in 2000, the repealed and re-

enacted of Investment and Securities Act No. 45 amongst others (Nwankwo, 2011, Izedonmi and

Abdullahi, 2011, Iganiga, 2010)

Table 4.1.2 above and figure 4.1.2 below are schedule and chart representing the summary of the

average values of the variables employed in the study. Firm performance proxy by return on asset

(ROA) and variants of leverage ratios such as total debt ratio (TDR), long term debt ratio (LTDR)

and short term debt ratio (STDR) were proxies for financial structure. A cursory look at the charts

depicts different behaviours among the variables. Steep downward and upward fluctuations

exhibited by ROA is attributed to internal and external characteristics of the firms (Barney, 2001),

while, between 2005 and 2007 recorded a significant slope in the graph pointing to reforms in

financial and real sectors of the economy as noted earlier. Specifically, average performance of

Nigerian quoted firms in 2001 was 13.73% and decrease to 12.4% and 12.1% in 2002 and 2003

respectively. But latter appreciate slightly to 12.5% in 2004 which is attributed to campaign of

2005 banking consolidation that led to pool of money into capital market. Performance of Nigerian

quoted firms were drastically poor with 8.59% and 8.74% average value in 2005 and 2006

respectively, while improvement were recorded in the remaining years of the study with varying

average value of 10.93%, 13.73%, 11.67%, 12.78%, 13.15% and 9.37% but apparently at very low

performance rate.

A mere look at the chart below revealed high leverage ratio of the sample firms, average total debt

ratio of 62.87% in 2001 revealed that Nigerian quoted firms were highly geared exposing fixed

interest investors to high risk. Consequently, the ratio is an indication that any depletion of total

Table 4.1.2: Summary of the Average Values of Research Variables

72

assets of the firms above 37.13% incorporate debt holders’ funds that is any risk investment

undertake by the firms is covered by 37.13% equity capital of the firms. The leverage ratio of the

firms over the years were at a very high rate with varying rate as specifically indicated by 2002

total debt ratio of 63.86%. Thus implies that risk investment undertaken in that year was only

covered with 36.14% owners’ equity. Total debt ratio as at 2003 was 62.84% and equity holders’

capital investment was 37.16% and this is a reverse of bondholders as the risk taker in the firm.

However, average total debt ratio of the sample firms remained high at slightly decreasing and

increasing rate over the subsequent years, accordingly recorded as such; 61.65%, 65.67%,

65.11%, 65.08%, 62.89%, 63.63%, 58.9%, 61.45% and 60.97% in 2004, 2005, 2006, 2007, 2008,

2009, 2010, 2011 and 2012 respectively. Apparently, the total debt ratio of the sample firms over

the duration of the study revealed high leverage ratio which in turn exposes firms to high risk,

financing constraint, high cost of financing and agency cost among other costs.

Long term debt ratio shows obligation of Nigerian quoted firms that are made to be repayable after

more than one year as indicated in table 4.1.2 above. In 2001 8.47% average value was recorded

and thus indicates moderate rate when compare with total assets of the firms but this increased to

10.46%, 10.65%, 11.13%, 14.42% in 2002, 2003, 2004 and 2005 respectively, which implies that

this measure was at an increasing rate (upwards slope) right from 2001-2005. Accordingly, the

remaining years from the period of study recorded downwards and upwards slope as recorded in

2006 where average ratio decreased to 14.08% but latter increased to 15.17% in 2007 with

subsequent decreased and increased such as 14.71%, 15.94%, 16.75%, 19.90% and 18.19% in

2008, 2009, 2010, 2011 and 2012 respectively. Short term obligations payable within one

accounting period showed that average short term debt ratio of the sample firms was 54.54% in

2001. Thus revealing high leverage ratio and exorbitant cost to the firms where total investment of

the firm is financed with 54.54% short term capital and the reminder financed with long term

capital comprising of owners equity and long term liabilities of the firm. Apparently, this is sign of

regular refinancing imposing high weighted average cost of capital to the firms, high risk

investment due to mismatch of funds resulting to relatively high agency cost to the firms. The

following three accounting year recorded downward slope with average value of 52.44%, 51.94%

and 50.53% in 2002, 2003 and 2004 respectively. Conversely, 2005 revealed upward slope with

average value of 51.27% but downward slope in 2006 with 51.03% and latter increased in 2007

with average value of 51.36%. The remaining period of the study indicated a downward slope with

The mean of ROA for the sample firms is 11.7%, this indicates that for every N100 worth of total

assets of the firms, mere N11.7 was earned as profit before interest and tax. Thus implies that

Nigerian Quoted firms using this accounting measure of firm performance have a very low

performance rate. The lower returns on ROA may have also been affected by firm’s leverage ratio.

For example, the TDR recorded a mean of 62.80%, which implies that little depletion in assets of

Nigeria quoted firms will affect bondholders’ funds since owners stake in the firm cover only

37.20% of the firm’s assets and thus contributing to high agency cost and reorganization cost

reflecting low returns. LTDR having lower mean value of 14.10% compare to STDR value of

48.70% confirmed high cost of debt financing incurred by the sample firms due to refinancing

cost. Firm size and age was 2115.1% and 373.5% respectively. The consequences and implication

of the result obtained so far is well revealed by the median, maximum, minimum, standard

deviation, among other measures in the results. This result is acceptable as was confirmed with P-

value less than 0.05 in all the indicators.

The result of correlation matrix for the variables is reported in order to examine the correlation

between the dependent and explanatory variables. The results show that there is a negative

relationship between ROA and financial structure measures (TDR, LTDR and STDR), while

positive relationship was revealed between ROA and firm characteristics measures (firm size and

age). This implies that financial structure does not improve firm performance which may be

attributed to high cost of debt capital making sample firms vulnerable to agency problem. The

results obtained so far may be also be attributed to mismatch of funds by firms’ agents (managers),

which is considered to be detrimental to shareholders’ earning. Meanwhile, the above correlation

results agree with studies including Khan (2012), San and Heng (2011), Onaolapo and Kajola

(2010), Ebaid (2010) among others. It is however inconsistent with the findings of Mojtaba and

Shahoo (2011), Zuraidah et al., 2012 among others.

The result in table 4.2.1 above shows that none of our correlations (both negative and positive

coefficients) are high enough to warrant any problem of multicollinearity. Hence, the result of our

regression estimates is less likely to be biased by the problem of multicollinearity. This appears to

indicate that it may be statistically tolerable to use pooled ordinary least square regression

technique to estimate the specified model.

4.3 Hypothesis Test

The three hypotheses formulated in chapter one of the study were tested along the lines of the

model specified for empirical verification of the hypotheses in chapter three (3.5). Employing

panel data of the quoted Nigerian firms, pool Ordinary Least Square (OLS), Fixed Effects (FE),

and Random Effects (RE) regression estimation were adopted. Furthermore, as revealed earlier in

the previous chapter, dependent variable of this study is ROA. This was tested on the financial

structure measures and reported accordingly. The hypotheses were postulated in null and

alternative form. To this end, all the operation was performed with the aid of E-View version 7.0

and the results were analysed as follows:

4.3.1 Hypothesis One

The hypothesis is restated in null and alternative forms as follows;

H0: Total debt ratio does not have positive and significant impact on firm performance.

H1: Total debt ratio has positive and significant impact on firm performance.

ROA = - 0.032 – 0.0776TDR + 0.0086SIZE + 0.0044AGE

The result above revealed that the intercept (constant) of the equation is -0.032. This value is

negative and statistically significant since P-value is less than 0.05 level of significant, indicating

that ROA will decrease by 0.032 unit when there is no change in explanatory variables. However,

the negative coefficient of TDR (-0.0776) indicates that a unit increase in TDR of the Nigerian

quoted firms resulted to 0.0776 unit decrease in firm performance. The P-value of 0.000 less than

significant level of 0.05 confirms significance result. As also revealed by the coefficient of

determination (R2), which is the proportion of variation in the dependent variable explained in the

regression model. The R2 of 0.0689 indicates that 6.89% of the variation in the dependent variable

(ROA) was explained by the independent variable, while the remaining 93.11% was due to other

factors not presumed in the variation model. R2 was again adjusted to 6.88% to eliminate any form

of error that could result in biasness.

The control variables introduced indicates that while firm size had positive and significant impact

on firm performance (coefficient of SIZE = 0.0086, p-value = 0.000), firm age had positive and

significant impact on performance of Nigerian quoted firms within the period under review

(coefficient of AGE = 0.0044, p-value = 0.0219).

Decision Rule

The results showed that total debt ratio has negative and significant impact on firm performance.

Hence, we reject the alternative hypothesis and accept the null hypothesis. The study thus conclude

that total debt ratio has negative and significant impact on firm performance. This is very

consistent with existing propositions that Nigerian debt market is underdeveloped; most firms’

external debt finance is majorly short term finance, imposing extra burdens at very exorbitant costs

on the firms. The adjustment of leverage ratio to attain optimal financial structure may lead to

high agency cost if not rationally employed. As documented, the optimal financial structure

decision has to do with balancing the trade-off between the benefit of debt and agency costs arising

from mitigating the agency cost of managerial discretion against the agency cost of debt arising

from “asset substitution effect” (Octavia and Brown, 2008 and Shahjahanpour et al. 2010). Also

high leverage ratio increases the bankruptcy cost and agency cost of the firm as well rises.

4.3.2 Hypothesis Two

The hypothesis is restated in null and alternative forms as follows;

H0: Long term debt ratio does not positively and significantly impact on firm performance.

H1: Long term debt ratio does positively and significantly impact on firm performance.

ROA = -0.0458 – 0.0479LTDR + 0.0081SIZE – 0.0004AGE

The above table showed that the intercepts is -0.0458. The value is negative and statistically

significant as justified by the p-value which is less than 0.05. The implication is when no change

occurs in long term debt ratio, ROA decrease by 4.58%. The coefficient of LTDR revealed

unexpected on the direction but expected on the magnitude. From the result, 1 unit increase in

LTDR of Nigeria quoted firms resulted in 0.0479 unit decrease in ROA. The p-value of 0.000 less

than 0.05 indicates significant result. The coefficient of determination which measures the

goodness of fit of the model as revealed by R-square (R2) indicates that 3.32% of the variations

observed in the dependent variable were explained by variations in independent variable. The test

of goodness of fit as indicated by R2 was adjusted by the Adjusted R-Square to 3.31%. This is

relatively tiny, indicating that there are other variables apart from the independent variable that

have impact on firm performance. The control variables introduced indicates that firm size had

positive and significant impact on firm performance (coefficient of SIZE = 0.0081, p-value =

0.000), while firm age had negative but insignificant impact on performance of Nigerian quoted

firms within the period under review (coefficient of AGE = -0.0004, p-value = 0.839).

Decision Rule

The regression results showed that long term debt ratio had negative and significant impact on firm

performance. Thus, the null hypothesis is accepted while the alternate hypothesis is rejected.

Accordingly, the study concludes that long term debt ratio have negative and significant impact on

firm performance. Manos and Ah-Hen (2002) pointed that agency consideration assume debt is

valuable in reducing the agency costs of equity but at the same time debt is costly as it increase the

agency cost of debt. Thus, high leverage increases agency problem, firm needs to balance the cost

and benefit of debt because negative information in debt about profitability overwhelms any tax

(or other) benefits of debt (Fama and French, 1998).

4.3.3 Hypothesis Three

The hypothesis is restated in null and alternative forms as follows;

H0: Short term debt ratio does not have positive and significant impact on firm performance.

H1: Short term debt ratio has positive and significant impact on firm performance.

ROA = -0.0491 – 0.0804STDR + 0.0087SIZE + 0.0055AGE

Again, the trend value of the above hypothesis testing is negative (-0.0491) but statistically

significant at 0.05. The trend value of -0.0491 is the regression line intercept showing that ROA of

Nigerian quoted firms decreased by 4.91% when there is no change in the independent variable.

The negative coefficient of STDR (-0.0804) is inconsistent as expected. It means that 1 unit

increase in STDR of Nigerian quoted firms induce a decrease in ROA by 0.0804 unit, and the p-

value is significant wherein 0.000 is less than 0.05. The coefficient of determination which

measures the goodness of fit of the model as revealed by R-square (R2) indicates that 6.47% of the

variations observed in the dependent variable were explained by variations in the independent

variable. The test of goodness of fit as indicated by R2 was adjusted by the Adjusted R-Square to

6.46%. As observed from the table, the control variables introduced indicates that firm size

(coefficient = 0.0804 and p-value = 0.000) had positive and significant impact on firm

performance within the period under review, while firm age (coefficient = 0.0055 and p-value =

0.0042) had negative and significant impact on firm performance within the period of study.

81

Decision Rule

The results showed that short term debt ratio had negative and significant impact on firm

performance. Therefore, the null hypothesis is again accepted while the alternate hypothesis is

rejected. The study thus concludes that short term debt ratio have negative and significant impact

on firm performance attributed to high short term debt and mismatch of fund. Apparently, when

leverage becomes relatively high, further increases generate significant agency costs of outside

debt; including higher expected costs of bankruptcy or financial distress, arising from conflicts

between bondholders and shareholders (Jensen and Meckling, 1976). Also at high leverage the

value of shareholders may not be enhanced when restrictive covenants included in debt financing

agreements limit the ability of firms to fully harness the potentials of the firm’s resources

(Onwumere et al., 2011). Thus firm can only maximize their values by maximizing the use of debt.

4.3.4 Discussion of Results

This section is devoted to ascertain whether the objectives set out in the research are actually

achieved. The results from the three hypotheses are compared with the objectives of this study.

Again, the panel data study results of the three regression estimations (OLS, Fixed Effects and

Random Effects) are compared among others.

Apparently, there exists strong evidence from the results which point to the achievement of the

objectives originally established for the study. As revealed from table 4.3.4 below, the three

hypotheses had negative and significant impact in the three adopted regression estimations.

To ascertain the impact of total debt ratio on performance of quoted firms in Nigeria. The results

proceeding from the descriptive statistics and test of hypothesis one established that this objective

was achieved. The results from the three regression estimation showed that total debt ratio had

Table 4.3.4 ROA vs Financial Structure Measures

82

negative and significant impact on firm performance. The negative effect is associated with high

leverage ratio of Nigerian quoted firms as confirmed in descriptive analysis, and also frequent

changes in debt capital of Nigerian quoted firms are highly associated with systematic depreciation

of firms’ assets attributed to high cost of debt financing. The findings as revealed in the regression

results is consistent with the findings of Khan (2012), San and Heng (2011), Onaolapo and Kajola

(2010), Ebaid (2009), Zeitun and Tian (2007), Abor (2008), amongst others, but in contradiction

with that of Mojtaba and Shahoo (2011), Zuraidah et al. (2012), amongst others.

To determine how long term debt ratio impacts on performance of quoted firms in Nigeria. Using

panel data, the study showed that long term debt had negative and significant impact on firm

performance. This is attributed to inconsequential financing pattern of most of the sampled firms

due to the under developed security market which overwhelmed the conventional element of

financial leverage. To examine the impact of short term debt ratio on performance of quoted firms

in Nigeria. The three regression estimation confirmed that short term debt ratio had negative and

significant impact on firm performance. The result is in line with the findings of Zeitun and Tian

(2007), Zuraidah et al.(2012), Khan (2012), Ebaid (2012) among others.

However, theoretical body of knowledge argues that debt provide tax shield, thus debt is cheaper

source of financing than equity to certain extent. After certain level, the cost of debt outweighs the

tax benefits. From the analysis, we observed that the sample firms are highly levered. This

confirmed the contention that at low levels of debt, substitution effects are likely to become

vanishingly small. Indeed, when debt claims remain riskless, both the asset substitution and under

investment problems disappears but at high level of debt, reverse is the case (Cuny and Pirinsky,

2004).

4.4 Robustness Test

To test for robust of our regression results, we conducted additional test using alternative measure

of firm performance such as return on equity (ROE). Regression results from the three adopted

regression estimation were recorded in table 4.4 below.

Note: (1) Regression significant at 5% level of significance.

(2) The Larger the value of t (t > P-value) the stronger the evidence that the coefficient is significant.

Testing from the standpoint of Return on Equity (ROE), the study revealed that total debt ratio had

positive and significant impact on return on equity as alternative measure of firm performance.

This outcome also compare favorably with the findings of Ebaid (2012). It is also consistent with

cost-benefit argument of trade-off theory and tax shield benefit found by Miller (1977) to

contribute to incremental value of shareholders’ earnings when debt capital is employed.

Again, the study showed that Long Term Debt Ratio had positive and significant impact on return

on equity of Nigerian quoted firms under the period of study. The outcome here again is consistent

with our prediction and priori findings (Zuraidah et al., 2012).

Lastly, comparing STDR with ROE, the regression results showed that the impact of short term

debt ratio on return on equity as alternative measure of firm performance was negative and

significant. The negative and significant relationship documented between short term debt and

return on equity is consistent with the findings of Amjed (2008); Zuraidah et al., (2012). This

confirmed the argument that significant and justifiable results are better obtain with narrow

definition of leverage ratio in compliment of the cumulative. It is remarkable that this is a basis to

ascertain actual impact of leverage on returns that is “impact base” on the periodic employment of

debt that hedge against fund mismatch. The observation is consistent with Titman and Wessels

(1988) assertion that significant results are good reason for employment of different measures of

leverage ratio because some of the theories of capital structure have different implications for not

combining them as aggregate “debt ratio”. The negative effect is an implication of under

developed debt market where major debt financing of most Nigerian quoted firms are short term in

nature placing high burden and cost on the firm, thereby decreasing returns on their equity capital.

CHAPTER FIVE

SUMMARY OF FINDINGS, CONCLUSIONS, AND RECOMMENDATIONS

5.1 Summary of Findings

Based on the regression results of the hypotheses tested, the following are the summary of our

findings:

1. Total debt ratio have negative and significant impact on the performance of Nigerian

quoted firms.

2. Long term debt ratio have negative and significant impact on the performance of Nigerian

quoted firms.

3. Short term debt ratio have negative and significant impact on the performance of Nigerian

quoted firms.

5.2 Conclusion

This study as one of the empirical investigations of the impact of financial structure on the

performance of Nigerian quoted firms. The ultimate goal of the firm is to ensure optimal

employment of capital, which in turn triggers long run value maximization of owners’ equity.

Agent(s) of the firm is left with financial structure decision and other corporate financing decisions

that most be align to attain “value maximization”. These decisions are very crucial one in

transitory economies peculiar to Nigeria couple with underdeveloped debt market and numerous

intrinsic market risks. The impact of financial structure on the firm performance has been

significantly verified in the study.

To this end, the impact of financial structure (total debt ratio, long term debt ratio and short term

debt ratio) on the performance of Nigerian quoted firms has established negative and significant

results, thus being consistent with agency cos theory. This confirmed that Nigerian quoted firms

borrows to point where the marginal value of tax shields benefits on additional debt could not

offset the incremental cost of debt capital thereby contributing negatively to firms’ earning. And

also the findings of the study are in line with other previous empirical studies as already

highlighted in the main discussion of the findings. The above implication revealed that value

Page 101: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

88

maximization firm in Nigeria needs to maintain financial structure that tax benefits of debt

overwhelmed bankruptcy cost and agency cost associated with debt.

Meanwhile, in determining the extent of the influence of financial structure on the performance of

Nigerian quoted firms using alternative measure of firm performance (ROE), some of the

indicators (financial structure variables) showed diverse outcomes due to different implications of

maturity rate of debt finance and mismatch of fund. Total debt ratio and long term debt ratio were

found to have positive and significant impact on return on equity of Nigerian quoted firms, while

short term debt ratio had negative and significant impact on return on equity of Nigerian quoted

firms. The sign on short term debt ratio is an indication of mismatch of funds as well as high cost

burden of short term finance on quoted firms attributed to underdeveloped security market living

no option but bank loans at high interest rate.

Above all, the regression results provide strong support for the proposition that financial structure

is relevant in explaining performance of Nigerian quoted firms. In view of this caveat and

indistinct nature of financing decision spawning the gap among researchers on the relevance of

financial structure on firm performance, the results of this study should not be view as conclusive

empirical evidence, but rather as an additional motivation for further research in this area.

5.3 Recommendations

The findings of this research have provided enough evidence to advocate that financial structure of

Nigerian quoted firms have relevance role to play on their performance. Irrespective of detrimental

influence of the security market subjecting financing decision of most firms, the influence was

convincing one. Much therefore needs to be done to put the security market in the right

standard/track for efficient and effective mobilization and allocation of funds, and firm agents on

the other side have a major role to play. To achieve this requires the unceasing efforts of all

stakeholders.

5.3.1 Recommendations for Selected Stakeholders

i. One significant outcome of this study is that unexpected disparity in some of the findings is

attributed to high cost of funding and mismatch of funds. Therefore, there is need for change in

the attitude of banks towards manufacturing firms so that they can provide easier access to long

Page 102: ITIRI, IDAM OKPARA IDAM OKPARA... · model to test the hypotheses of the study. Financial structure proxied by total debt ratio (TDR), long term debt ratio (LTDR) and short term debt

89

term bank financing. This will encourage growth of manufacturing and the subsequent

development of the real sector of the economy as a whole.

ii. The study found that Nigerian security markets are not efficient in location of funds. Therefore,

that government should pursue genuinely a policy measures targeted at developing the security

market to ensure high volume of corporate debt issue, liquidity of the market and market

efficiency in order to guarantee easy mobilization and allocation of funds.

iii. The study also found that agents of the firms were not balancing the tax shield benefit of debt

against agency cost of debt resulting to depletion in firm earnings. Therefore, there is need to

ensure policies that will enjoin Nigerian quoted firms on corporate governance to achieve

efficient financial structure. Inefficient corporate governance structures exacerbate the prevailing

agency problems, with managers taking advantage of the situation.

iv. Measures directed towards elimination of restrictions of the public sector on issuance of debt

finance which would result in an increase in economic activity and improving efficiency of

Nigerian quoted firms should be strictly stipulated. These flexible by-laws should be in form of

real sector resuscitation that will tend to boost the economy afterward. An example of such

legislation is government intervention by means of bail-outs of the real sectors. Ensuring

effectiveness and efficient implementation of the policy formulation that will improve the

performance of Nigerian quoted firms.

v. Owners of the firm and/or agent(s) of the firm need to ensure optimal employment of debt and

equity finance. This suggests that a firm should borrow to the point where the marginal value of

tax shields on additional debt immediately offset the increase in the present value of bankruptcy

cost.

vi. There is need to ensure value maximization of shareholder funds by the agent(s) of the firm. This

can only be achieve by aligning investment decision of the firm with the appropriate financing

decision given consideration to maturity structure of external debt capital. Taking cognizance of

this by the firm policy makers will result to minimal mismatch of funds, in turn low risk, low

cost of funds and high returns to the firm.

vii. Bank loans as observed from the financial statement of the sample firms which is responsible for

corporate performance is at present not performing to expectation due to dearth of long term

finance in the security market. Thus, the excessive liquidity in the Nigerian money market

prompt the need for capital market instruments that extend for long maturity period to bridge the

gap between the excess liquidity and the scarce investment funds.

5.3.2 Recommended areas for further research

The findings of this study have exposed other areas of research that will help the understanding of

the effect of the mix of debt and equity finance phrased “financial structure” on the performance of

Nigerian quoted firms.

i. The study found that marginal value of leverage on additional debt capital could not offset

the long run incremental cost of debt capital when firms are highly levered. This prompt

the need to design model and determine optimal financial structure of Nigerian quoted

firms.

ii. It was inferred from the study that there is evidence of mismatch of funds among the

Nigerian quoted firms resulting to high risk and cost of funds. It will make a good research

sense if future research should investigate debt maturity and performance of Nigerian

quoted firms.

iii. Although, the study sheds light on the role of security market in determining the risk and

cost of finance and in turn returns on the invested capital. And also, it was noted that apart

from internal efficiency that determine the variation of financial structure and performance,

there are external determinants that could explain such variation. Further research could

incorporate important macro-economic factors, for instance non debt tax shield could be

adjusted for inflation to find out the actual economic depreciation.

iv. Notwithstanding concrete evidence established by the study, this study can be improved

upon if the cross-section dimension (number of firm) and time dimension (timeframe) are

increased to have greater number of observation. Also adoption of market performance

measures could strengthen the deduction on the impact of financial structure on firm

performance.

v. Finally, small and medium scale firms that is vulnerable to financial constraint in

developing nation. The focus of the impact of financial structure on the performance of this

class of firms could strengthen the relevance and/or irrelevance arguments.

5.4 Contributions of the Findings of the Study

The results of this research work have provided a basis for a better understanding and appreciation

of the impact of financial structure on performance of Nigerian quoted firms. Among other things,

the study has revealed the effect of firm characteristics on the firm performance measures. As a

result, the above research outcomes are expected to contribute to both overall development and

knowledge in significant manner.

A. Contribution to development

Information to stakeholders in the security market.

This research work is of great relevance to all stakeholders in the security market. Apparently, the

study will aid investors in the debt market to deduce the intrinsic value of their financial assets as

appropriate risk are readily available based on the established leverage ratio of the sample firms.

Precisely, it has suggested to these stakeholders, the need to ascertain owners’ stake on the firm

given the ratio of external and internal capital of the firm which is the major pricing factor as well

as risk determinant of the investment. On the other hand, the study is relevant to the owners of the

firm or agent of the firm on the way to reduce the price of their external fixed capital thereby

ensuring minimal inherent risk of the assets to improve their earnings ratio.

Policy guide to regulators and agencies

The study has provided required empirical and theoretical base concerning the impact of financial

structure on the performance of quoted Nigerian firms and working of Nigerian security market.

Such insight will offer useful guide to these regulators in designing appropriate workable device

for efficient regulation of the market. Besides, it will provide useful platform that could assist these

policy makers enunciate favourable means of mitigating aberration in the market and in turn

ensure efficient market.

Inducement and mobilization of investment funds

Capital as the bedrock for economic growth and development. The evidence established in this

research has revealed the revelation of security market stipulation on the earnings of the firm.

Therefore, it provides useful information for firms and financial intermediaries to stimulate growth

by participating and ensuring smooth running of the market.

92

Financial analyst and other market agent

This research is relevant to financial analyst and other market agent to infer the nature of equity

investment and position of Nigerian quoted firms at minimal variation of projection and actual

outcome as well as the risk of interest bearing assets. And also enable market agents to restrained

unwholesome practice in financing pattern of most firms when the real class of firm’s assets is

obtainable.

B contributions to knowledge

Above all, this research has assisted in broadening the frontier of knowledge in various ways. First,

the study has exposit a unique modeling framework for financial structure and performance of

Nigerian quoted firms which captured major definition of financial structure giving consideration

to maturity effect of debt, given incremental cost relatively to intrinsic risk.

Secondly, this research has also contributed to the enrichment of literature on funding decision by

developing countries in which external fixed capital are highly short term in maturity thereby

possessing various attribute and relative influence on the firm. Thirdly, it has empirically

suggested ways to ensure efficient market and minimum market risk and variation in projection

and actual returns. Lastly, the study has provided vital information to guide future researchers.
