1.1 INTRODUCTION
This study examines the impact of working capital management components on the
profitability of registered companies in Pakistan. In addition, the study determines how
the impact of working capital management components changes as macroeconomic
conditions change from a boom to a recession.
This chapter is organized as follos!
It brings light on working capital management as well as on the trade-off between liquidity
preservation and profit maximiation faced by companies.
It describes the problem statement under investigation and further expounds on the trade-off
emanating from managing working capital. It chronicles the main ob!ectives of the study and
is followed by section.
It specifies the key questions to be examined by the study. It also highlights the importance of
this study and pin-points the gaps in theoretical and previous studies that this research seeks to
fill in. "t the end of this section of the chapter outlines how the entire research paper is
organied.

The thesis will provide a snapshot of how public listed firms manage their working capital
during both good and bad period. This management of working capital needs to be assessed
which is done with its effect on firm#s profitability. In this concern, the better working capital
is managed to help in maximiing higher profitability of a firm. Then on the basis of this
information the best way of managing working capital is assessed for both periods. $oreover

(iii Third to determine if the impact of working capital management components on
profitability of companies in the industrial sector and those in the rest of the other
sectors is different. The underpinning for this investigation of the impact in different
sectors is that, relative to the rest of the companies in the other sectors, companies
in the industrial sector (which comprise manufacturing and production led
firms have significantly higher levels of current assets on their respective
balance sheets. Thus, the ob!ective is to examine if there is a difference in the
direction and extent of the impact on profitability if working capital levels change
from significantly high levels to relatively low levels.

9econdly, the study investigates the relationship between capital structure and
profitability of Pakistan#s firms where limited empirical research exists. 4iven that
capital structure is viewed by a number of researchers to be the most vital of all the
aspects of capital investment decision, the study therefore examines its relationship with
profitability so as to give guidance to management in their attempt to identifying the
optimal capital structure of the firm that maximies market value.
Thirdly, the scope of the research has been stretched to explore if the selected liquidity
measures impact on profitability of companies in the industrial sector and those in the
rest of the other sectors different. This will give guidance to corporate managers in
adopting an appropriate trade credit policy applicable in their sector.

".1 INTRODUCTION
'irst studies on this area suggest the existence of a linear relation between working capital
management and firms# profitability. Thus, firms can maximie profitability and minimie
associated risks through an efficient management of working capital accounts. In fact,
manager#s goal is to improve financial performance through working capital policies.
/orking capital management has been a concern for all firms but small firms should give
more importance to this issue because they cannot afford to survive without cash. $any
researchers have worked on the same issue but pioneer study found that working capital
management strongly affects the corporate profitability. Therefore cement industries should
address this issue seriously. They suggested that conventional approach that is to invest high
in working capital can increase profitability. They investigated = performed the research to find
out the relationship between working capital management and firm#s profitability by taking
net trading cycle as a measure of working capital management on specific industry, the result
was not that substantial. "fter observing the nature and sie of the industry, they
recommended that forceful liquidity management increase the profitability.
/orking capital is an important tool for growth and profitability for company. /orking
&apital is being required at a certain level otherwise if the levels of working capital are
insufficient then, it could lead to shortages and problems with the day-to-day operations.

$ostly in manufacturing company#s inventory contain of raw materials, work in progress,
factory overhead and final products. "ll these levels of inventory need to be financed by the
efficient management which can increase a firm#s profitability. Ideal inventory levels depend
on sales, so sales must be the first step before target setting inventories can be made. Eesides
these errors in setting inventory levels lead to lost sales or inventory management, excessive
carrying costs plays a very important role. Therefore, firms use classy computer systems to
monitor their inventory system. Inventory management may be considered as outside the
main stream of finance, it is however necessary to highlight its importance and potential
effects to corporate profitability of manufacturing companies.

system, which is equally important. &orrect actions are mostly required, more so, the only
means of understanding if the condition is getting out of hand is with good receivable control

" credit policy consists of the following four variables. &redit period is the length of time
given to buyer for payment of their purchases for example, the credit period might be one
month. &ustomers prefer longer credit periods, so delaying the period will motivate sales.

that the customer will default and the account will end up as a bad debt.
Disco6nts
The companies offer their customers discounts for the early payment. The discounts describe
the percentage reduction and how rapidly payment must be made to be eligible for the
discount. There are two benefits regarding offering discounts. 'irst, the discount amounts to a
price reduction and lower prices encourage sales. 9econd, discounts will cause some
customers to pay earlier than they otherwise, which will shorten the cash conversion cycle.
Gevertheless, discount mean lower prices, therefore lower revenues due to the quantity sold
increases enough to offset the price reduction. The gap between benefits and costs of discounts
must be balanced if a rational decision about them is to be made.
'. CA%H *ANA8E*ENT
"ll most businesses are conducted by their own nature. Therefore an integral part of working
capital management is the effective cash management level, which contains a method of
transfer of funds from where they come in, to where they are needed, depending nowhere it is
lacking and where it is in excess. To most of us Hcash# conventionally means money, bonds
and shares which can easily convertible in to cash including deposits in the bank. The financial
experts have mentioned in their research about cash holdings, deposits demand, and securities
that are easily convertible at a predictable price and thus are converted to bank deposits. That#s
why, AcashB as reported on balance sheets generally includes short -term securities, which are
also called Acash equivalentsB.
The following levels are used to optimie demand deposits holdings. There are three motives
for a company to hold cash
-
8/12/2019 Prints Final
11/52
%. Transaction motive, a company needs certain level of cash to meeting their daily
transactions, such as payment for supplier, salaries and so on. &ash management ensures
company to meet their regular cash outflow.
). Precautionary motives describe the cash flow which is difficult for a company to predict
that#s why companies take steps to prevent from the unexpected cash flow in future because of
the huge gap between the firms and industries. &ash management can help to relieve the
problem of sudden cash needs, for example, raised cost of raw material and default of third
party.
. 9peculative motives business cannot predict about the future it can only speculate,
unexpected investment opportunities can increase, sufficient cash holding allows the company
to take advantage of these opportunities and grow in the future.
&ompanies can en!oy several benefits under holding sufficient cash. 9till, it cannot provide a
good business environment3 it can earn interest if they are used in the proper investment.
;esearchers have raised two questions in their investigation
(i There is an optimal cash level that can maximie firm value.
(ii 'irm value can be reduced if the cash deviates from the optimal level.
;esults describe that there is a relationship between cash holding and firm value, which
means that optimal cash level that take advantage of firm value occur. It shows that firm value
will be decreased if the cash holding is different from this optimal level. The result shows that
Trade-off theory can also explain that there is an optimal level of cash holding which can
balance the marginal benefit and cost. These results show that having optimal cash holding is
the central task of cash management.
The researcher mentions that two constraints which decide how much cash a firm should
maintain.

(ii 9elf-imposed balance,
(i &ompensating balance
The balance which is required for the services that are rendered by banks to the firms is known
as compensating balance.
(ii 9elf-imposed balance,
The balance which is calculated by considering factors like the need for cash, the predictability
of this requirement, the interest rate on marketable securities or the borrowing rate, and the
fixed cost of affecting a transfer between marketable securities and cash or effecting a loan
transaction. It is the balance which is self-imposed for the need of certain transactions.
8utcomes confirm that cash holding enable firms to take profitable investment opportunities,
which leads to the point that cash holding level of growth firm is higher than the matured
firms. They also find that the factors of cash holding are different between growth firms and
matured firms. &ash holdings in growth companies decrease with the raise of firms#
characteristics sie, level of liquid assets and sort-term debt. Fowever, in matured firms,
cash level shows a positive relationship with firm sie and dividend pay-out and negative
relationship with firms# research and development expenses. /ith In a similar study, cash
holding level in firms from &anada is strongly affected by their market to book ratio, cash
flow, net working capital leverage, and firm sie explain the optimiation problem of meeting
demands for cash over time with cash deposit in bank or invested in stock. 9tudy shows the
solutions of optimal level of cash
'irm#s future performance in poorly corporate governance will be reduced since cash can be
dissipated very fast. 8n the opposite side, in well-governed firms, firms# future operating
performance will get a big improvement due to the negative impact of cash holding can be

The result of the preceding literature review on working capital management is that while
working capital management components may impact on profitability of firms, there is
uncertainty regarding both the appropriate variables that might serve as alternatives for
working capital management as well as on the direction of the impact of different components
on profitability. In his research, $athura ()*%* finds that there exists a highly significant
positive relationship between the period taken to convert inventories into sales and
profitability, which finding is contrary to that of 5eloof ()** whose study findings conclude
that there is a negative relationship between day#s sales in inventory and profitability. This
therefore shows that there is no clear-cut direction of the relationship between any of the
variables of working capital management and firms profitability. The differences in the
direction of the impact could be attributable to any one of the following factors

5iagnostic tests are robust statistical tests carried out to verify if the data used have met the
assumptions underlying the ordinary least squares regression and where possible to
remove problems associated with panel time series data. 9ome of the problems of panel time
series data include heteroskedasticity, multicollinearity, and auto-correlation, among others.
The diagnostic tests carried out in the study are detailed below.

8ne of the main assumptions for the ordinary least squares regression is the similarity of the
variance of the residuals. If the variance of the residuals is non-constant, then the
residual variance is heteroskedasticity making the regression estimates, namely coefficients
and standard errors, to be biased if the models are not re-specified or variables not
transformed. "s per equation %% below, heteroskedasticity means that the variance of the
error term is not constant overtime.

This study uses the Ereusch-Pagan test in all the two regression model specifications to
verify whether or not heteroskedasticity is present in the models. The null hypothesis is that
the variance of the residuals is homogenous. Tables 6 and < below present the Ereusch-Pagan
test results for heteroskedasticity for model specification I and II respectively. The results
show that the variance of the error term in each model specification is not constant, which if
not corrected leads to biased standard errors. The presence of heteroskedasticity was however
controlled by using the ArobustB command when performing both regressions, resulting in
generation of Arobust standard errorsB. ;esearchers state that the Arobust standard errorsB
address the problem of errors that are not independent and identically distributed and that
the use of Arobust standard errorsB does not change the coefficient estimates provided by
the ordinary least squares, but change the standard errors and significance tests.
'.." TE%T $OR *U)TICO))INEARIT&
Eoth regression models were tested for multicollinearity. The primary concern with
multicollinearity is that, as the degree of multicollinearity increases, the regression
model evaluation of the coefficients become unstable and the standard errors for the
coefficients can get inflated. The variance inflation factor (JI' is used to detect whether one
predictor has a strong linear association with the remaining predictors (the presence of
multicollinearity. @aaridis and Tryfonidis ()**> proclaim that JI' measures how
much of the variance of an estimated regression coefficient increases if predictors are
correlated. $ontgomery and Peck ()**1 suggest that when JI' is greater than 6-+, then the
regression coefficients are poorly estimated. In this study, we used the JI' command when
regressing profitability against the explanatory variables. The predictors had resultant
variance inflation factors ranging between %.6 and .1 across both model specifications as
shown in Table > below. The results indicate that there is absence of multicollinearity between
predictors in the regression models. Tolerance, defined as %=JI', is the inverse of JI'.

4iven that the cash conversion cycle is made up of other ratios used in the study, namely
days sales in receivables, days sales in inventory, and days payables outstanding,
to avoid multicollinearity problem, the two model specifications were developed separating
one model containing the cash conversion cycle from the other containing days sales in
receivables, days sales in inventory, and days payables outstanding.

This chapter discusses and compares results of the study with findings by other studies
elsewhere that explored the relationship between working capital management and firm
profitability.
It highlights relations between findings of this study and those of previous studies.
'urthermore, the section provides suggestions on what could be the primary differences
between findings of this study and those of previous studies. It concludes the chapter and is

management on firm#s profitability in the cement sector of Pakistan. To carry out the research
data from %D cement industries which are currently listed at Carachi 9tock :xchange is
analyed. The results shows that profitability of cement industries are significantly affected by
the efficient management of working capital and working capital management play a vital role
in creating a value for the shareholders.
.' CONC)U%ION
The main purpose of the study is to draw the results about the firm#s profitability in the
working capital management. This study investigates how relatively large public listed
companies in the can manage their working capital in the most profitable way, during non-
crisis periods and during a crisis period. /orking capital is studied as a whole, but its parts are
also studied individually. The non-crisis period and crisis period are then compared with each
other and differences are highlighted.
The aim of this research is to test whether firm value can negatively relate to cash conversion
cycle in the sample of cement factory, and how working capital management affects firm
value.
.+ I*P)ICATION%
$any recommendations can be drawn from the above research results. :very cement factory
should give due importance to working capital management. &ement industries should make
such collection and payment policies which are in favor of the firm and existing policies
should be thoroughly reviewed. &ement industries should decrease there payment and
receivable cycle. This can only be done when there will be professional management. The
results suggest that cement industries should keep optimum level of inventory and cash
conversion cycle. This could only be possible when cement industries will give due
importance to every component of cash conversion cycle. &ement industries should hire
professional human resource to take decisions related to finance. 9ince the sample comes from

an important element of working capital. The application of the result from cement industry
can be limited to other industry. 9econdly, the sie of sample is rather small. The accuracy of
result can be affected. 5ue to the limitation of database, there are only )D> observation are
available, this can be the drawback of study. Thirdly, there may some outliner exist in the
sample, which may cause skewness in the result.
There are many cement industries where only one person is looking after the whole
department. In order to maximie the profit cement industries should manage there working
capital efficiently.
. $UTURE R E%EARCH
:very sector in manufacturing sector should be analyed at micro level for efficient working
capital management so it can be understand that which factors affects the working capital
management more and how working capital management can increase profitability in different
sectors of our country. The scope of future investigation can be extended to focus on the detail
of relationship between each component of working capital management and firm value or
other performance. :specially focus on 5ays 9ales 8utstanding and 5ays Payable 8utstanding
since they are not significant in this airline industry study. $ore substitutes of firm value and
working capital management can be applied into the research in order to make sure findings are
more accurate.
