Impact of Working Capital Management on Return of Shareholders: A Study on Lafarge Surma Cement Ltd. in
Bangladesh
Abstract
This study is designed to investigate the correlation between working capital management and the return of shareholders of the
Lafarge Surma Cement Ltd. and to justify whether the Profitability is affected by working capital management. Correlation Matrix
and Regression Analysis, with the help of SPSS, have been used to show correlation between working capital management and the
return of shareholders and the impact of working capital management on profitability respectively. For the source of data I mainly
relied on Annual Reports and official records as well as primary data collected through interview. It is observed from the study that
the managers of the company can create value for the shareholders by delaying payments to creditors and by reducing the credit
period granted to their customers, days inventory and cash conversion cycle to an optimum level.
Key Words: Profitability, Working Capital Management.

Introduction:
A financial manager in any organization has to play three functions. Those functions are (i) the management of long-term assets, (ii) the
management of long-term capital and (iii) the management of short-term assets and liabilities. The management of short term assets and
liabilities refers to management of Working Capital (Khan, 2002). To produce the best possible returns, firm should keep no unproductive assets
and should finance with the cheapest available sources of funds. In general, it is often advantageous for the firm to invest in short-term assets and
to finance with short-term liabilities (Scherr, 2007). The management of working capital plays an important role in maintaining the financial
health of the firm during the normal course of business (Zariyawati, Annuar, Taufiq and Rahim, 2009).
A firm is required to maintain a balance between liquidity and profitability while conducting its day to day operations. Liquidity is a
precondition to ensure that firms are able to meet its short-term obligations and its continued flow can be guaranteed forms a profitable venture
(Padachi, 2006). Working Capital Management includes maintaining optimum balance of working capital components – receivable, inventory
and payables and using the cash efficiently for day-to-day operations. Optimization of working capital balance means minimizing the working
capital requirement and realizing maximum possible revenues (Ganesan, 2007). There is a strong relationship between the firm’s profitability
and its working capital efficiency (Shin, 1998; Dong and Su, 2010; Lazaridis and Tryforidis, 2006; Olufemi and Olubanjo, 2009, Gill, Biger and
Mathur, 2010).
Shareholders’ return often refers as the profitability. The term profitability refers to the ability (of a firm) to earn profit. Profit is determined by
matching revenue against cost associated with it (Salauddin, 2001). Profit of an enterprise in absolute figure gives an idea about the result of its
operation. Profitability is a widely used financial measure of performance. The concept of profitability may be used in two senses:
commercial/private profitability and public profitability. Although the use of public profitability which is based on economist’s notion of cost
5 | P a g e
and benefits from social point of view, that is true opportunity cost and the benefits for the society as a whole, appears to be a more appropriate
measure of performance of public enterprises, the measure of commercial profitability has been used in this study.
This is because of the fact that commercial profitability is widely used to measure the performance of public enterprises in Bangladesh and even
in other countries of the world like India, UK, and France etc. and also for its general acceptance and ready understandability. Two major types
of profitability ratios are computed: (i) Profitability in relation to sales and (ii) Profitability in relation to investment. Gross Profit Margins
(GPM), Net Profit Margin (NOM), Return on Total Assets (ROTA), Return on Equity (ROE), and Return on Investment (ROI) are the main
measure of profitability. Therefore, profit is an absolute measure and profitability is a relative measure of efficiency of the operations of an
enterprise.
The researcher has used correlation matrix and regression analysis to examine the relationship between profitability and working capital
management. Some statistical tools like mean, standard deviation were also used to evaluate the performance.
Objectives of the study:
The major objective of the present study is to examine and evaluate the correlation between working capital management and shareholders’
return in Lafarge Surma Cement Ltd. over a period of five years from 2005 to 2009. The specific objectives of the study are as follows:
i. To assess the relationship between working capital management and shareholders’ return.
ii. To show the impact of working capital management on the return of shareholders.
iii. To suggest some measures for improvement in working capital management.

Literature Review:
In attention to discover the relationship between working capital management and firms’ profitability, Zariyawati, Annuar, Taufiq and Rahim
(2009) used 1628 firm-year observations from listed firms in Bursa Malaysia to examine the relationship between working capital management
and firm profitability. They used cash conversion cycle as measure of working capital management. They found strong negative significant
relationship between cash conversion cycle and firm profitability.
Sayaduzzaman (2006) in his article on “Working capital management: A study on British American Tobacco Bangladesh Company Limited”
mentioned that the efficiency of working capital management of British American Tobacco Bangladesh Company Ltd. is highly satisfactory due
to the positive cash inflows, planned approach in managing the major elements of working capital. He found that working capital management
helps to maintain all around efficiency in operations.
Gill, Biger and Mathur (2010) researched the relationship between working capital management and profitability by using 88 American firms
listed on New York Stock Exchange fro a period from 2005 to 2007. They found statistically significant relationship between the cash
conversion cycle and profitability measured through gross operating profit. They also concluded that manager can create profits for their
company by handling correctly the cash conversion cycle and by keeping accounts receivable at an optimal level.
In the article “Liquidity-Profitability Tradeoff: An Empirical Investigation in an Emerging Market” Eljelly (2004) examined the relation between
profitability and liquidity by using correlation and regression analyses and found that the cash conversion cycle was of more importance as a
measure of liquidity than the current ratio that affects profitability.
Raheman (2007) studied the effect of different variables of working capital management including the Average Collection Period, Inventory
Turnover in Days, Average Payable Period, Cash Conversion Cycle and Current Ratio on the Net Operating Profitability of Pakistani Firms. By
using Pearson’s correlation and regression analysis he found that there was a strong negative relationship between variables of working capital
7 | P a g e
management and profitability. He also found that as the cash conversion cycle increases it will lead to decrease in profitability of the firm and
managers can create a positive value for the shareholders by reducing the cash conversion cycle to a possible minimum level.
In the article “Working Capital Management and Corporate Profitability: Evidence from Panel Data Analysis of Selected Quoted Companies in
Nigeria”, Olufemi and Olubanjo examined the effects of working capital management on profitability performance for a panel made up of a
sample of Nigerian quoted non-financial firms for the period 1996-2005. The study revealed that there was a significant negative relationship
between net operating profitability and the average collection period, inventory turnover in days, average payment period and cash conversion
cycle.
Islam & Rahman (1994) conducted a study on working capital trends of enterprises in Bangladesh. They found that optimum working capital
enables a business to have its credit standing and permits the debts payments on maturity date and helps to keep itself fairly in liquid position
which enables the business to attract borrowing from the banks.
Deloof (2003) surveyed on Belgian Firms to find out whether the working capital management affects profitability. He found that most firms had
a large amount of cash invested in working capital. It can be expected that the way in which working capital is managed will have a significant
impact on the profitability of those firms. Using correlation and regression tests he found a significant negative relationship between corporate
profitability and number of days accounts receivable, inventories and accounts payable of Belgian firms. On the basis of these he suggested that
manager could increase corporate profitability by reducing the number of days accounts receivable and inventories to a reasonable minimum.
The negative relationship between accounts payable and profitability is consistent with the view that less profitable firms wait longer to pay their
bills.
Padachi (2006) found in his research study that a firm is required to maintain a balance between liquidity and profitability while conducting its
day to day operations. The manager of a business entity is in a dilemma of achieving desired trade-off between liquidity and profitability in order
to maximize the value of a firm.
Lazaridis and Tryfonidis (2006) investigated relationship between working capital management and corporate profitability of listed companies in
the Athens Stock Exchange. The results of the article showed that there was a statistically significant relationship between profitability and the
8 | P a g e
cash conversion cycle. Moreover manager could create profits for their companies by handling correctly the cash conversion cycle and keeping
each different components (accounts receivables, accounts payables, inventory) to an optimum level.
Ganesand (2007) suggested that efficient working capital management increases firms’ free cash flow, which in turn increased the firms’ growth
opportunities and return to shareholders.
Chowdhury and Amin (2007) work an article on “Working Capital Management Practices in Pharmaceutical Companies Listed in DSE”. Among
all the problems of financial management the problems of working capital management have probably been recognized as the most crucial one.
It is because of the fact that working capital always helps a business concern to gain vitality and life strength and to maximize profit.
Shin and Soenen (1998) suggested that efficient working capital management was very important for creating value for the shareholders. The
way working capital was managed had a significant impact on both profitability and liquidity. Using correlation and regression analysis they
justified the relationship between the length of net trading cycle, corporate profitability and risk adjusted stock return. They found a strong
negative relationship between lengths of the firm’s net trading cycle and its profitability. In addition, they also found that shorter net trade cycles
were associated with higher risk adjusted stock returns.
Methodology:
Data Collection:
Data were obtained from Lafarge Surma Ltd. which is enlisted in Dhaka Stock Exchange in Bangladesh. The study covered a period of five
years from 2006 to 2009. This study was based on both primary and secondary data. The primary data were collected through personal interview
9 | P a g e
with officials of the company under study. Secondary time series data were taken to see the link between profitability and working capital
management. For that the published annual reports of the selected company for the study period were considered. Moreover extensive literature
survey was done by searching different libraries.
Variables:
The variables used in this study based on previous researches about the relationship between working capital and profitability. Net profit margin
(NPM) that is measure of profitability of firm and return on total assets (ROTA) that is measure of overall profitability are used as dependent
variables.
Number of days accounts receivable (ARD) used as proxy for the collection policy is an independent variable. Number of days inventories used
as proxy for the inventory policy is an independent variable. Number of days accounts payable used as proxy for the payment policy is an
independent variable. The cash conversion cycle used as a comprehensive measure of working capital management is another independent
variable. Various studies have utilized the control variables along with the main variables of working capital in order to have an opposite
analysis of working capital management on the firm’s profitability (Deloof,2003; Lazaridis and Tryfonidis, 2006; Dong and Su, 2010; Gill,
Biger and Mathur, 2010). The logarithm of sales used to measure size of a firm is control variable. In addition financial debt ratio used as proxy
for leverage and ratio of fixed financial assets to total assets are also control variables in the regression.
The collected data were analyzed and interpreted with the help of different financial ratios, statistical tools like Mean, Standard Deviation (S.D.)
and Correlation Coefficient etc. With the help of SPSS, Correlation Matrix and Regression analysis were also forced out for analysis.
Variables used in the analysis can be calculated as follows:

Findings and Discussions:
This section has three parts. The first part of the section showed the descriptive statistics. The second part focused on correlation between
shareholders’ return and working capital management and the last part showed the impact of working capital management on the return of
shareholders.
Descriptive Statistics:
Table 2 provides descriptive statistics of the collected variables from the company (Lafarge Surma Company Ltd.) which is enlisted in the Dhaka
Stock Exchange for a period of five years from 2006 to 2009 and for a total 90 firms-year observations. All variables were calculated using
balance sheet (book) values. The book value was used because the company did not provide any market value related to the variables that are
11 | P a g e
used in this study. When market values are considered in such studies, there is always a legitimate question of the date for which the market
values refer. Hence, I relied on book values as of the date of the financial reports

From the table2, it is seen that the average value of net profit margin is-37.79 % and standard deviation is 71.51%. This figure means that the
value of net profit can deviate from mean to both sides by 71.51%. The maximum and minimum values of gross profit margin are 1% to 62%
respectively. The overall profitability measured by return on total assets has a mean of 1% and standard deviation of 5.97% which indicates that
the value of return on total assets can deviate from mean to both sides by 5.97%. The maximum and minimum values of return on total assets are
6% to 7% respectively.
The mean of cash conversion cycle that used as a proxy to check the efficiency in managing working capital is 190.83 days and standard
deviation is 293.93.97days. The average of number of days accounts receivable is 12.81 days with standard deviation of 12.70 days. . Minimum
time taken by a cement company to collect cash from customers is 2.20 days while the maximum time for this purpose is 30.68days. The average
time of paying to suppliers is 236.90 days and the standard deviation is 367.67 days. Maximum time taken from firm to pay their suppliers is 287
days while minimum time taken for this purpose is 32.77days. Moreover, it takes an average 787.61days in order to sell inventory with standard
deviation of 107.58 days. Maximum time taken by a firm is 482 days, while minimum time to convert inventory into sales is 119 days.
Natural logarithm of sales that measure the size of the firm is used as a control variable. From Table 2 it can be seen that the mean of logarithm
of sales is 15.08 and standard deviation is 1.79. The maximum value of log of sales for a firm in a year is 16.35 while the minimum value is
12.47. Debt ratio is used to check the relationship between debt financing and the profitability. It is also used as a control variable. The result of
descriptive statistics indicates that the average of debt ratio is 53.30% with standard deviation of 31.45%. The maximum debt ratio financing
used by a firm is 76% which is unusual because of debt larger asset. However, it is also possible if the equity of the firm is negative. While the
minimum of debt ratio is 7%, this means that there is a company that uses a little debt in its operation.
Finally, the fixed financial assets to total assets ratio is used to check the ratio of fixed financial assets to the total assets of company of
Bangladesh. It is also utilized as a control variable. The mean value for this ratio is 8.99% with a standard deviation of 1.75%. The maximum
value of financial assets to total assets is 11% and the minimum value for this purpose is 7%.

Correlation Analysis:
The correlation between working capital management and return of shareholders of Lafarge Surma Cement Ltd. can be assessed through
Pearson’s Correlation Coefficient. The following Table 3 shows the relationship between the efficiency of working capital position and
profitability of company for the study period. The efficiency of working capital has been shown through the current ratio (CR), accounts
receivable days (ARD), inventory days (INVD), accounts payable days (APD) and cash conversion cycle days (CCCD) of the company. The
profitability position has been shown through net profit margin (NPM) and return on total assets (ROTA).

It is seen from the table 3 that accounts receivable days has a negative correlation with net profit margin (--.833) and return on total assets (.037). The relation between accounts receivable days and net profit margin is statistically significant at 1% level of significance. This means that if
number of days accounts receivable increase then net profit margin and return on total assets decrease and vice versa. The number of days
inventory has a negative relation with net profit margin (-.982) and return on total assets (-.192). But these relations are not statistically
significant. The relation states that if the number of days inventory increase then net profit margin, return on equity and return on total assets
decrease and vice versa.
It has been found that the number of days accounts payable has a negative relation with the net profit margin ( -.980) and return on total assets
(-.916). The relation between the number of days accounts payable and return on total assets is statistically significant at 5% level. The relation
implies that if the number of days accounts payable increase return on total assets increase and vice versa. It is also revealed from the table that
the cash conversion cycle has negative relation with net profit margin (-.982) and return on total assets (-.925). The relation between cash
conversion cycle and return on total assets is statistically significant at 5% level. Result of analysis also shows a positive significant correlation
between natural logarithm of sales that is used to measure the size of a firm and net profit margin (.995). The natural logarithm of sales has a
positive correlation with return on total assets (.440) which is not statistically significant. It shows that as size of the firm increases, it will
increase net profit margin and it will increase return on total assets.
The earnings in terms of sales can be assessed through the profit margin. Net profit margin reveals the overall profitability of the concern, that’s
why it is very useful to the proprietors and prospective investors. It also indicates management efficiency in manufacturing, administrating and
selling of the products. Return on total assets is calculated to measure the profit after the tax against the amount invested in total assets to
ascertain whether assets are being utilized properly or not. Therefore, to conclude it can be said from the analysis that the overall profitability
(return on total assets) and net profit margin (NPM) can be increased by decreasing accounts receivable days, inventory days and cash
conversion cycle in days and by delaying payments to creditors.

Multiple Regression Analysis:
In this section it has been constructed a model that indicates the impact of working capital policy on the return on shareholders. Return on
shareholders can be measured by NPM (net profit margin) and overall profitability ROA (Return on Total Assets) of the company. For this
purpose the secondary time series data have been used. In this model an attempt has been made to trace out the impact of overall working capital
policy on the shareholders’ return. In the study, it was selected a number of variables to construct the model and finally settled with the
following best variables on the basis of their partial correlation coefficient. Thus the model is:
Y=f (ARD, APD, INVD, CCCD, FFAR, FDR, LNSALES)
Yit=β0+β1ARDit+β2FFARit+β3FDRit+ β4LNSALES+єit

Where, Y= NPM, ROTA
Where, the subscript i denoting Lafarge Surma Cement Ltd. company ranging from 1 to 18 and t denoting years (time series dimension) ranging
from 1 to 5. The variables are NPM, ROTA, ARD, APD, INVD, CCCD, FFAR, FDR, and LNSALES. In the model NPM and ROTA are the
dependent variables. ARD, INVD, APD and CCCD are independent variables.
While, FFAR, FDR and LNSALES are used as control variables.

Conclusion:
Considering the coefficients and their significance level it can be concluded that in Lafarge Surma Cement Ltd., Number of days accounts
receivable (ARD), Number of days inventory (INVD), Number of days accounts payable (APD), Cash conversion Cycle in days (CCCD), Fixed
financial assets ratio (FFAR), Financial debt ratio (FDR), Natural logarithm of sales (LNSALES) play an important role in determining the
company’s Net profit margin (NPM), overall profitability Return on Total Assets (ROTA).
From the correlation matrix it is clear that there is negative correlation between working capital efficiency and profitability ratios of the selected
Firm with some exception where the correlation is positive. It can be concluded from the correlation matrix the net profit margin and return on

total assets can be increased by collecting cash from credit sales as early as possible and by reducing days inventory and by reducing cash
conversion cycle at minimum possible level. On the other hand the net profit margin and return on total assets can be increased by delaying
payments to the creditors. From the regression model for NPM it is seen that the coefficients of ARD, INVD and CCCD are negative and the
coefficient is positive for APD which is consistent with the correlation matrix. It is also revealed from the regression model of ROTA, the
coefficients of ARD, INVD and CCCD are negative and the coefficient of APD is positive. This is evident from the study that the manager of
Lafarge Surma Comapany can create value for their shareholders by reducing accounts receivable days, inventory days and cash conversion
cycle days and by increasing accounts payable days.

Notes:
What Does Financial Asset Mean?
An asset that derives value because of a contractual claim. Stocks, bonds, bank deposits, and the like are all examples of financial assets.
Financial Assets include cash and bank accounts plus securities and investment accounts that can be readily converted into cash. Excluded are
illiquid physical assets such as real estate, automobiles, art, jewelry, furniture, collectibles, etc., which are included in calculations of Net
Worth. A financial asset is an intangible representation of the monetary value of a physical item. It obtains its monetary value from a
contractual agreement of what it represents. While a real asset, such as land, has physical value, a financial asset is a document that has no
fundamental value in of itself until it is converted to cash. Common types of financial assets include certificates, bonds, stocks, and bank
deposits.
