The results of research devoted to the analysis of interrelation between an index of information disclosure
and cost of equity of the Kazakhstan companies are presented in article. On the basis of the analysis of the existing
empirical researches the index of disclosure of information for 37 Kazakhstan companies was constructed and the
regression analysis of influence of an index of disclosure of information on the cost of equity of the company is
carried out. The results received by the author show that the index of information disclosure on this selection has
negative impact on the cost of equity of the company. The level of disclosure in companies of Kazakhstan was
revealed due to the content and analysis of annual reports. Today the level of corporate information disclosure is low,
the majority of them show that companies get only the best results and nobody shows their flaws. Results indicate
that firms are statistically significant and value of a different market cost of the capital is important in the level of
information disclosures. The present research is the first to reveal the connection between discosure and cost of
capital for firms which are in bad institutional regimes. The research contributes to already existing researches on
defining the theoretical and methodical approaches.
Key words: disclosure policy, cost of equity capital, regression analysis.
This study explores the extent and levels of corporate disclosures in the annual reports of the
listed companies on KASE in Kazakhstan, a growing emerging country. The disclosure of financial
information in annual reports is a key area of accounting research and, more specifically, corporate
disclosure has received a great attention to the academicians and several research is done both in
developed [1] and developing countries, however, a very few attention is done in Central Asia
in general and Kazakhstan in particular. The annual report is a significant element in the overall
disclosure process, because it is the most widely disseminated source of information on publicly held
corporations.
Disclosure refers to providing information which enables stakeholders to evaluate future
performance of a company. Disclosing information reduces information asymmetry between firms and
stakeholders. It plays a role in closing the information gap between the two parties, thus permitting
stakeholders to make healthier decisions about companies.
The available literature has suggested many ways in which a firm or its management can benefit
from enhanced disclosure. Moreover, while information disclosure is socially desirable, the tradeoff
between its benefits and costs may lead to partial or no disclosure, and one thereupon should decide
whether the disclosure should be voluntary or mandatory. In addition, the economic and accounting
literature has asserted that, in the view of informational asymmetry, (costless) disclose of private
information brings general gains in economic efficiency.
There are several motivations for the present study. Although there is a growing body of research
on disclosure practices of firms, many of the studies have been conducted in developed countries.
Aljifri and Hussainey (2007) point out the scarcity of studies that have investigated disclosure of
corporate information in developing countries, this observation also holds true for Kazakhstan which
is an important developing country in CIS region with its rapidly growing economy. In addition,
the subject has not been studied as much as other areas of information disclosure, such as social,
environmental, and intellectual capital. Furthermore, sufficient knowledge is lacking with respect to
the factors that influence disclosure.
The firm’s decision to voluntarily disclose information depends on its conjectures about the
beliefs held by competitors and investors. The study of Milgrom and Grossman concluded that
if the firm can make credible disclosures about its value to uninformed investors, in equilibrium the
firm will disclose all of its information regardless of how good or bad are the news. Many recent
studies have hypothesized that firms’ voluntary disclosure choices are aimed at controlling the interest
conflicts among shareholders, debt holders, and management [2]. It is meant that the extent of these
160
interest conflicts, hence the incentives behind voluntary disclosure choices vary with certain firm
characteristics.
There is an important strand of the financial accounting literature that investigates the relation
between disclosure and cost of equity capital. The basic idea is that higher levels of disclosure
contribute to a reduction in information asymmetry between managers and investors and, consequently,
cause a reduction in the idiosyncratic component of cost of equity capital. However, results of these
investigations have not been conclusive. Some authors argue that the absence of statistical and
economically significant associations between disclosure and cost of capital can be the result of
measurement problems because both variables are not directly observed and proxies need to be used.
Specifically, several studies justify that higher quality financial disclosures are positively
associated with general market liquidity, institutional ownership, analyst forecast accuracy and analyst
following, and are negatively associated with the ex ante cost of equity capital and agency costs [3].
Other benefit from improving disclosure is that providing better information firms try to reduce
potential investors’ estimation risk regarding the parameters of a security’s future return or payoff
distribution. It is assumed that investors attribute more systematic risk to an asset with low information
than to an asset with high information.
Hypothesis Development.
Size
Size is identified as a significant explanatory variable in explaining variation in the level of
voluntary disclosure in previous studies. In literature, a number of theoretical explanations for expecting
a positive relationship between company size and level of voluntary disclosure were provided. Agency
theory suggested that agency costs are associated with the separation of management from ownership,
which is likely to be greater in larger companies. A number of reasons have been advanced in the
literature in an attempt to justify this relationship on a priori grounds. Ahmed and Nicholls argued
that it is more likely that large firms will have the resources and expertise necessary for the production
and publication of more sophisticated financial statements and, therefore, exhibit more disclosure
compliance and greater levels of disclosure. Lang and Lundholm and McKinnon and Dalimunthe
pointed out that large firms tend to have more analyst followings than small firms and therefore may
be subjected to greater demand for information. These lines of reasoning provide strong grounds
for predicting that larger companies are more likely to disclose voluntary information than smaller
companies. Thus, it is hypothesized that:
Hypothesis 1: There is a positive relationship between firm size (as measured by market
capitalization) and the level of information disclosure.
Leverage
It has been proposed that the capital structure of a firm is related to agency cost. Agency costs
(e. g., incurred by monitoring costs) are higher in highly leveraged firms (i. e., more debt in the
capital structures) because a large proportion of debt allows greater potential wealth transfers from
debtholders to shareholders. Thus, agency theory predicts that corporate disclosure is expected to
increase with leverage. Also, highly geared firms have a wider obligation to satisfy the needs of their
long-term creditors for information compared to lower geared firms.
Information disclosure may be used to avoid agency costs and to reduce information asymmetries.
Therefore, it is argued that leveraged firms have to disclose more information to satisfy information
needs of the creditors. Hence, the following hypothesis 2 was formulated:
Hypothesis 2: There is a positive relationship between leverage (as measured by the ratio of total
liabilities to total assets) and the level of information disclosure.
Cost of equity capital
Disclosure also creates shareholder value by allowing a firm to reduce the cost of its capital.
The majority of the studies show this positive impact [4]. By revealing private information firms
try to solve the reluctance of potential investors for holding shares in illiquid markets, and thus,
reduce the cost of capital. In this line, Diamond and Verrecchia show that companies reduce the cost
of equity financing by improving disclosures, which implies higher liquidity of firms securities and
increase the demand from large investors. Other benefit from improving disclosure is that providing
better information firms try to reduce potential investors’ estimation risk regarding the parameters of
a security’s future return or payoff distribution. It is assumed that investors attribute more systematic
risk to an asset with low information than to an asset with high information.
161
Thus, whether disclosure is useful in reducing the cost of equity capital becomes an empirical
issue, which can be tested by using the following hypothesis:
Hypothesis 3: There is a negative association between disclosure and the company’s cost of equity
capital.
Sample Construction and Data Description
The main objective of this study is to investigate whether firms that publish greater disclosure
benefit in terms of a lower cost of equity capital. Disclosure of financial information is measured using
a disclosure index developed from a content analysis of annual reports. The approach implemented
in this study involves the use of a dichotomous procedure, where a particular information item is
awarded one (for yes) and zero (for no) if it is disclosed or not disclosed, respectively. The level of
disclosure for each firm is then calculated as the total number of items scored (total count of all the
ones and zeros).
In using the disclosure index approach, it is first necessary to develop a checklist of items of
information that firms disclose or may disclose [5]. In this research, a checklist comprising 79 financial
disclosure items was developed.
The present research attempts to measure directly the cost of equity capital through Capital Asset
Pricing Model. The analysis is based on companies’ annual reports based on a sample extracted from
the KASE. The selection procedures yield 37 Kazakhstan companies. The focus on KASE firms will
ensure that the sample includes some multiple listed companies and that all companies are subject to
approximately equivalent levels of disclosure pressures arising from various regulatory and capital
market regimes.
Sample selection
Initially we considered all the companies for which we have disclosure data for years 2006 and
2012. Then we have to exclude all companies for which some of the data needed in order to calculate
the cost of equity capital measure were missing. Then we eliminated companies with incomplete or
missing financial data. We ended with a final sample of 37 Kazakhstan firms that are listed on the stock
exchanges. In order to be included in the study, a firm must have a full set of financial information
covering the entire fiscal year.
Disclosure data
Several items are graded in order to produce a score that measures the quality of the information
provided in the annual report. Among them we find: historical data, analytical account of results,
composition of shareholding, shares percentage held by the board of directors, order and clarity of the
report, design, number of branches, directors’ remuneration, returns on shares, review of operations,
on-line information.
Each question is evaluated on a binary basis to ensure objectivity, and rankings for the three
broad categories and an overall ranking is developed from the answers to individual questions. These
categories broadly correspond to the analytical criteria employed in Standard and Poor’s corporate
governance scoring process. They address disclosure patterns along a broad spectrum of factors that
affect corporate governance practices. This presentation format provides analysts and investors the
flexibility to focus on specific investment analysis needs. One point is awarded for each attribute that
is found to be present.
Using the content analysis method, the extent of compliance of listed financial and non-financial
Kazakhstan companies with the required disclosures is measured by using disclosure index. Disclosure
indices are extensive lists of selected items, which may be disclosed in company report.
Financial data, used to construct control variables as well as measures of return, are taken from
Bloomberg and S&P Capital IQ and analytical reports, published by Halyk Finance for Kazakhstan
firms. Corporate disclosure variables (e.g., board composition and ownership concentration) are
constructed using manually collected data gathered from annual reports and government sources.
Research Design and Methodology
The Model
The statistical analyses performed in the present research, includes the use of multiple linear
regression models to examine the relationship between annual report disclosure level and the
influencing factors.
162
We test our hypothesis by regressing expected cost of equity capital (COE) on market beta
(BETA), the natural log of market value (LMVAL), financial leverage (LEV), book to market value of
equity (BM) and total disclosure score (DISCL). That is,
COE = α + β
1
BETA + β
2
LMVAL + β

LEV + β

BM + β

DISCL + ε
(1)
In the present research, there are four independent variables indicating the financial characteristics
of the firm whereas there are three independent variables indicating corporate disclosure characteristics
of the firm. These include firm size, leverage and beta. These factors are the most commonly used
independent variables in the accounting disclosure literature [6] and will be used here for testing with
disclosure.
Control Variables
The literature has revealed several risk factors that affect the cost of equity. These factors must
be controlled for so that a correct inference can be obtained. In this study, we control for cross-firm
differences in beta, firm size, book-to-market equity and leverage.
The inclusion of firm size and book-to-market equity as our control variables is motivated by
Fama and French. Fama and French and Baginski and Wahlen find a negative relation between Size
and cost of capital. The log of the common equity of the firm scaled by the market value of equity,
BM, is included because Fama and French, Gebhardt et al, and Baginski and Wahlen find a positive
relation between BM and the cost of equity capital. LEV, measured as long-term debt plus any debt
in current liabilities divided by total assets, is included to proxy for the amount of debt in the firm’s
capital structure. Botosan and Plumlee find LEV to be positively associated with cost of equity capital.
However, as our estimated cost of equity is derived from BM, it is debatable whether BM should be
included as a control variable.
BETA is included in the models to control for systematic risk. BETA is estimated by the market
model using a minimum of thirty monthly return observations over the five-year period with a value
weighted S&P 500 market index return. Financial leverage (LEV) defined as the ratio of total debt
to market value of outstanding equity is used as proxy for a firm’s riskiness. The higher a company’s
relative debt position, the more likely it will face financial distress from defaulting on interest and
principal payments. BETA and LEV are included in the analysis to account for a company’s systematic
and financial risk. LMVAL is included to account for the richness of a firm’s information environment
as well as the significant association between cost of capital and market value.
Empirical Results. The firm characteristics used to describe the sample are market capitalization
(firm size), beta (market risk), leverage (financial risk), and book-to-market values. The data for
these characteristics are drawn from the analytical reports and the S&P. The statistics are presented in
Table 1.

Table 1 shows that the average firm size, measured in terms of the market capitalization, is
about $210 million. The median market capitalization is smaller than the mean at $1,62 million. This
suggests that the sample of firms also includes medium-sized firms. The table also reveals that BETA,
163
a measure of risk for the sample of firms in the study, is 0,9592. The median of 0,94 is slightly lower
than the mean suggesting that the sample includes some high and low risk firms.
The mean leverage of the firms is about 18,78% consistent with the notion that Kazakhstan firms
generally do not rely heavily on debt financing. The median is 14,15%. The fact that the median is
lower than the mean indicates that the sample includes low and medium-geared firms. Overall, firms
in the sample are lowly geared consistent with the notion that Kazakhstan firms rely more on equity
capital than on debt. In terms of the book-to-market ratio, the mean is 0,6773 and the median of
0,9363.
Relationship between transparency and cost of equity. We perform a cross-sectional time series
analysis of the relationship between information disclosed in company quarterly reports and cost of
equity and control variables.
At the first stage of data analysis cost of equity is dependent, company attributes including
transparency score are independent variables. The summary of data analysis regarding relationship
between cost of equity and disclosure score is as follows.

Table 2 shows summary of findings regarding relationship between cost of equity and company
attributes, which is proxied by BM (Book to Market Value), LMVAL (the natural log of market value),
BETA (market beta), LEV (financial leverage) and DISCL (total disclosure score) between 2006 and
2012 for the 37 sample companies from the KASE.
According to the results of the research, independent variables are statically significant at the 1%
level except BM variable. The results of the OLS regression show that F-ratio is 25,5 (p value less than
0,05). Hence, the model is statistically significant, with adjusted R-square equal to 81,94%. Regression
coefficient for firm size is negative and significant at the one percent level. The conclusion is that,
large firms tend to have lower cost of equity. Looking next at the variables, book to market value of
equity (BM) is not statistically significant. The coefficient for measuring company’s systematic risk
(BETA) is positive and statistically significant. On the other hand, the coefficient for transparency and
disclosure is negative and statistically significant that justifies the hypothesis about inverse relationship
between cost of equity and disclosure. In other words, the higher level of disclosure decreases the cost
of equity of the firm. The coefficient for financial risk (LEV) of the firm is positive and statistically
significant.

Table 3 shows summary of findings regarding relationship between disclosure score and company
attributes, which is proxied by MB (Market Value to Book Value), LMVAL (the natural log of market
value), BETA (market beta), LEV (financial leverage) and COE (cost of equity) between 2006 and
2012 for the 37 sample companies from the KASE.
The results show that independent variables are statistically significant at 1% and 10% level except
BM variable. The explanatory power of the model (adjusted R-square value) equals to 43,11%. The
regression coefficient for the firm size is negative and statistically significant that does not coincide
to the previous study results that the degree of corporate disclosure and transparency is an increasing
function of firm size. Although most previous studies support a positive relationship, there is an
unclear theoretical basis for such a relationship. The direction of association may be either positive or
negative.
The coefficient for BETA is positive and statistically significant, showing that the degree of
corporate disclosure and transparency are positively related to a measure of systematic risk of the
firm. The coefficient for COE is negative and statistically significant, thus supporting the research
hypothesis 1. The coefficient for measure of debt level (LEV) is positive and significant, showing that
firm with a greater amount of debt tend to have high degrees of corporate disclosure and transparency.
The results of the correlations between the financial disclosure and firm characteristics are given
in Table 4 Pearson correlation (s. 165). A correlation is a measure of the strength and direction of the
relationship and ranges between –1 and +1. The negative and positive signs reflect the direction of
the relation whilst the strength of the relation is reflected in the absolute value, called the correlation
coefficient. A higher correlation coefficient indicates a stronger relationship. Examining the Pearson
correlation coefficients (shown above the diagonal), we find that DI is negatively correlated with
lnMC, Correlation coefficient = –0,522. We find that lnMC is highly positively correlated with Lev
(0,840). In contrast, the correlation between DI and BtoMV is slightly lower with the coefficient of
0,409. A strong negative relationship exists between BtoMV and Lev with the coefficient of –0,910.
A negative relationship exists between Lev and Beta, the correlation coefficient is equal to –0,485.

Contribution and significance of the research
The significance of corporate disclosure practices has been of growing interest both in theory and
in practice. Today informational transparency of the company is an integral part of good corporate
governance that reduces the information asymmetry between agents and principals. Therefore, it is
interesting to measure the quality and quantity of transparency in Kazakhstan companies through
voluntary and mandatory disclosure of information on the corporate website and corporate reports.
The relevance of this approach is evidenced by the presence of a large number of empirical studies on
the issues of disclosure and transparency effects on the cost of equity capital.
Most research on disclosure quality and cost of equity capital relations has been conducted in
developed countries whereas empirical studies from Kazakhstan are very scarce. This research is the
first to perform a comprehensive investigation of the relation between disclosure and cost of capital
for firms immersed in poor governance and institutional regimes.
The study contributes to the existing research by justifying the choice of theoretical and
methodological approaches, construction of the disclosure index and the selection of factors for the
models based on the specifics of Kazakhstan.
Study of the relationship between corporate information disclosure and cost of equity, on the one
hand, is a very relevant issue and there has been significant interest in the foreign researchers that is
confirmed by the existence of a sufficiently large number of empirical studies in this area.
We should be cautious regarding the quality of information disclosed by the companies because
the information provided in financial reports may not be that quality like it seems so. For this reason,
it is the job of auditors to detect the mistakes, carefully check the quality of information disclosure and
make sure that it is reliable. Small firms provide less information than large ones, which supply more
information about their independence standards, audit committees, their management supervision
systems and whistle-blowing procedures. However, compared to small firms, large ones do not appear
to give superior information about their environment. These results obviously raise questions that
lie at the heart of most financial scandals as, in the end, firms’ size matters less than respecting good
governance, the latter being probably the main criterion to improve financial stability.
Much work should be done to improve the quality of financial information. In order to make financial
evaluations reliable, valid and comparable, the uniform internationally accepted standards must be
utilized. Although disclosure requirements have increased over the years, prescriptive disclosure has
not eliminated the differences in the quality and extent of disclosure offered by companies; significant
variation across companies is still observed.
