3.1 Introduction
The every business form has a relationship with its stakeholder. The all these
stakeholder interested to improve profitability, return on equity and return on
investment. Present chapter deal with analysis of return of equity of sampled units
using the DuPont model and profitability analysis of sampled units. The profitability
analyses have been done through various ratios and they compare with each other
lastly deal with correlation between selected variable and return on investment.
3.2 DuPont Analysis
The equity shareholder is real owner of the company. The every business
management focuses on improving wealth of equity shareholder. The equity
shareholder also happy with improving their wealth and as well return from
investment has been all ready invested. For this purpose return of equity is financial
ratio that shows how well the management has created value for shareholder. A higher
return of equity means return on shareholders‘ equity is giving up and that the
company doing a good job for improving profit without adding firm. The high and
consistent ROE can give a signal that the company has get competitive advantage
over its competitors. The after discussing the concept about ROE some question arises
to as that is how to define ROE and how to improve ROE by the company? There are
so many financial ratios liquidity ratios, debt or leverage ratios, efficiency or assets
management ratio and profitability ratios. That all ratios often hard to see big financial
picture. Excluding of all these one method that is specially for the business owner
[equity shareholders] called DuPont model. The DuPont model is able to show a
business owner where the component parts of the return of assets comes from as well
as the return on equity Ratio. The DuPont analyses also help to company is achieving
its ROE. The analysis of ROE using DuPont model are done in following two ways:
iii. ROE= Net profit margin * Assets Turnover * Equity multiplier.
− Net profit margin shows operating efficiency.
− Asset turnover shows assets utilization efficiency.
− Equity multiplier shows financial leverage.
111
Where, Net profit margin = Net income /Total sales
Assets turnover = Total sales / Total Assets
Equity Multiplier = Total Assets / Shareholder equity
Multiplying these three values resulting in ROE according to three step
DuPont model analysis. Concluded whether a company is increasing ROE through
improved profitability, Assets turnover and financial leverage, In Addition to this
some experts are saying that interest payments on debt effects net profit margin.
According to that one advanced versions was introduced that called advanced five
step DuPont analysis model.
iv. The five steps DuPont formula in an easy to understand form is given as below:
ROE= (Tax Burden) * (Interest Burden) * (operating margin)*(Assets
turnover)* (Equity multiplier)
− Tax Burden is the proportion of profit retained after paying Taxes.
− Interest Burden shows how interest is affecting profit. If company has
no debt the ratio will be 1.
− Operating income margin is the operating income per rupee of sales.
− Assets turnover shows assets utilization efficiency.
− Equity multiplier shows financial leverage
Where
Tax Burden = Net Income / EBT
Interest Burden = EBT / EBIT
Operating income margin = EBIT / Sales
Turnover = Sales / Total Assets
Equity multiplier = Total Assets / Shareholder Equity
When tax Burden, interest Burden and operating margin are multiplied to
gather, it gives us net income margin, and now it has been broken down further to
show how tax and interest effect on ROE.

The Table and figures 3.2.1 shows the year 2008 and after that rate was
decreased up to 6.07% in the year 2009. The year 2010 rate has been 11.74% and
11.00 % respectively. However in the last year of study period once again rate
decreased up to 8.79%. The rate of return on equity shares mix trend during study
period. The reason for decreasing the ROE in year 2008 and 2012 was lower net
income due to higher Interest expense even the EBIT satisfactory. The figure shows
the operating income margin positively correlated with return on equity.

The Table and figures 3.2.2 shows return of equity of HPCL using five step
DuPont model under study period. The rate of return of equity has been 12.913%,
5.35%, 11.26%, 12.61%, and 7.13% in the year 2008 to 2012 respectively over all
mix trend shows in rate of return during study period. The highest rate 12.913% in the
year 2008 and lowest rate 5.35 was next year 2009. In the year 2009 and 2012 the
Interest Expense has been higher compared other year under study period due to this
higher Interest Expense lower EBT and net income. The lower net income ultimate
reason for lower equity return. The management of HPCL need to cheaper rate debt
source. So EBT and net profit can be increase.
3.2.3 Return on equity of IOC

The table and figures 3.2.3 shows the return of equity on IOC during study
period. In the case IOC also shows lower return on equity in year 2009 and 2012. It
was only 6.70% and 6.83% in year 2009 and 2012 respectively. The year 2008, 2010
and 2012 rate of return on equity was 16.91, 20.21 and 13.46 respectively. This shows
satisfactory return in this three year. In the year 2009, assets turnover ratio is higher
(2.20) than year 2008 and 2010. It means in year 2009 revenue generation capacity
from the total assets was higher. Even though EBIT was is lower because of higher
operational cast. The lower EBIT main causes of lower return of equity. Same
situation happened in year 2012 also.

The table and figures 3.2.4 shows return of equity of MRPL during the year
2008 and 2012. The rate of return on equity in the year 2008 was 33.63% and then
after continuously decline up to 12.57% in year 2012.It mean in year 2012
approximately 62.61% rate was decline compare to year 2008. The operating margin
also decline 54.12% in year 2012 compare to year 2008. This shows lower level
operational efficiency under study period. For removing this critical condition
companies need to raise the revenue and control the cost both operating and financing.
So return of equity rate can be boost further.

The table and figures 3.2.5 figure shows the return of equity of NRL under
study period. The rate of return in year 2008 has been 16.58% and after that decline in
year 2009 and 2010. However in year 2011 ratio was increased up to 10.77%.
Unfortunately once again ratio decline by 3.99% [up to 6.78]. It shows fluctuating
condition in return on equity under study period. The proportion of tax Burden and
Interest burden has been decline it mean firm pay higher tax and higher Interest under
study period. So net operating margin ratio decline due to that over all return of equity
has been decline.

The figure3.2.6 shows return of equity of CPCL. The return of equity in year
2008 32.39% but after that in year 2009 rate has been negative because company
incurred less in year 2009. In the year 2009 fixed Interest. Expenses also high that is
more addition in the losses. In the year 2010 and 2011 company further increased
120
their return of equity up to 17.42% and 13.58% respect. However again in the year
2011- 2012 EBT was negative. Due to past accumulated profit operating Income
margin ratio has been positive. That is good sign for companies.

The table and figure represent Average return on equity of sample companies
under study period. The average return calculates using five step DuPont model. Five
steps tax burden, Interest burden, operating profit margin Assets turnover and Equity
multiplier or Leverage.
The tax burden shows tax payment of the firm per one Rs. Earnings before
tax. For example, Tax burden is 0.60 means, 0.60 net come and 0.40 taxes (1-0.60) for
one rupee on EBT. The considering the sample companies tax Burden of BPCL-0.67,
HPCL-0.81, IOC -0.79, MRPL -0.68, NRL -0.72, CPCL -0.53. In case of HPCL
highest tax Burden that is 0.81. It represents Rs. 0.81 Net incomes and only Rs.0.19
Tax for one rupee of.EBT. This show efficient tax planning compare to other sample
companies. The lowest tax Burden 0.53 in case of CPCL means Rs. 0.53 Rs. Net
income and Rs. 0.47 Tax for every one rupee of EBT. The company pays
approximately 50% Amt of EBT in the form of tax. It means critical tax planning
policy in CPCL.
Interest Burden shows how interest is affecting profit. The company use debt
source for mobilizing the fund then company must pay to some interest in the form of
fixed expense. The interest burden ratio shows payment of interest for 1 rupee of
EBIT. For example interest burden ratio 0.70 means 0.70 Rs. EBT and Rs. 0.30
interest for every one rupees of EBIT. The sampled companies tax Burden ratio 0.60,
0.53, 0.69, 0.92, 0.94, 0.57 in case of BPCL, HPCL, IOC, MRPL, NRL, and CPCL
respectively. The higher Interest Burden 0.94 in case of NRL mean healthy capital
structure compared to other sampled companies.
The operating profit ratio shows earning capacity to sales, or it represents
excess of sales over a cost. The avg. operating profit margin ratio of sampled
companies is 2.43% in case of BPCL, 2.36% in HPCL 3.82% in IOC 4.84% in MRPL
4.50% in NRL, and 2.90% in CPCL. The MRPL takes first place among the sample
companies on average operating profit margin ratio. The higher operating profit ratio
shows effective mgt. policy toward lowering cost on other hand considering the
operating profit margin ratio of HPCL stand the last place among the sample
companies. Higher level operating cost lead to lower level operating margin ratio in
HPCL.
122
The Assets turnover ratio shows uses efficiency of assets (utilization of
assets). The Assets turnover ratio of BPCL 2.74, HPCL 2.27, IOC 2.03, MRPL 2.55,
NRL 20.1, and CPCL 3.06. The highest assets turnover ratio was 3.06 times in the
CPCL. However CPCL incurred loss in some year under study period. This ratio is
show only utilization of assets not to cost and profit analysis. It means firm incurred
the losses with higher assets turnover ratio because of excess cost over sales.
The equity multiplier shows leverage situation or other words riskiness. The
equity multiplier shows portion of debt in total assets. Higher ratio shows higher
return but some risk arises. In case of BPCL, HPCL, and IOC equity multiplier ratio
has been 3.99 and 4.65 and 3.08. In case of MRPL, NRL and CPCL the ratio has been
2.87, 1.81 and 3.04 respectively. The NRL lowest equity Multiplier ratio shows
higher equity portion on total assets or lower leverage situation. The HPCL highest
ratio among sample companies shows higher debt and highly leverage firm.
The multiplication values of five ratios (shows in table3.2.7) give the overall
average ROE under study period. The average ROE ratio of sampled companies
10.63% in BPCL, 10.61% in HPCL, 13.16% in IOC, 22.26% in MRPL, 10.99% in
NRL, and -2.48% in CPCL.
The highest operating profit margin ratio with effective utilization of assets
and positive financial leverage MRPL stand in first rank for average ROE among the
sample companies. On other hand CPCL stand last rank because average ROE shows
negative sign. The negative sign was because of two year loss incurred by CPCL.
3.3 Profitability Analysis
The primary objective of the business undertaking is to earn profit. Profit
earning is considered essential for the business profits are the soul of the business
body without which the body becomes life less. Finance is heart of business body and
profit is the soul of business body. Profit has now become measurement test to
measure financial efficiency of the business firm. In other words of Lord Keynes.
―Profit is the engine that drives the business enterprise.‖
123
The company survives and grows over a long period of time. Profit is
essential, but it would be wrong to assume that every action initiative by the
management for maximization of profit, irrespective of social consequences. It is
unfortunate that the word profit is looked upon as a term of abuse.
Now a day‘s some firm always want to maximize profit at the cost of
employees, customer and society. Except such infrequent cases, it is a fact that
sufficient profit must be earned to sustain the operations of the business to be able to
obtain funds from investor for expansion and growth and to contribute towards the
social overhead for welfare of the society. The term profit and profitability is
difference. Profit is the difference between revenue and expenses over a period of
time. Profit is the ultimate output of a company and it will have no future, if it fails to
make sufficient profits. Therefore the financial manager should continuously evaluate
the efficiency of its company in term of profits.
The word profitability is composed of two word profits and ability. Profit has
been defined in number of ways. From accounting point of view, it is excess of
revenue after deducting expenses for given period of time and ability mean capacity
power.
The concept of profitability may define as the ability of a given investment to
earn a return from its use. Thus one can say that profitability means the ability to earn
the profit from the business.
The operational efficiency of the company was measure by the profitability
ratios. Besides the entire stakeholder like creditors, owners, and management of the
company interested in the profitability of the firm. Creditors want to get interest and
repayment of principal regularly owners want to get reasonable return on their
investment. This is possible only when the company earns enough profits.
Generally, two major types of profitability ratio are calculated.
1. Profitability in relation of sales.
2. Profitability in relation to investments.
124
Profitability in relation to sales indicates amount of profit per rupees of sales
similarly profitability in amount of profit per rupees invested in assets if a company is
not able to earn a satisfactory return on investment, it will not be able to pay a
reasonable return to its investors and survival of the company may be threatened. The
efficiency of the operation of the business is indicates by the profitability. Poor
operational performance may indicate poor sales and hence poor profit. A lower
profitability may arise due to the lake of control over the expenses. Bankers, financial
institutions and other creditors look at the profitability ratios as a an indicator whether
or not the firm earns substantially more than it pays interest for the use of borrowed
funds and whether the ultimate repayment of their debt appears reasonably certain
owner are interested to know the profitability as it indicates the return which they can
get on their investment.
The analysis of profitability ratios are to help to adequacy of profits earned by
the company and to discover whether profitability is increasing or declining. The
profitability of the firm is the net result of a large number of polices and decision. The
profitability ratios show the combined effect of liquidity, assets management and debt
management on operating results. Profitability analysis of cost of goods sold, analysis
of gross margin on goods sold, analysis of operating expense, analysis of profit in
relation to sales and capital. Profitability also indicates public acceptance of the
product or services rendered by the enterprise and shows the combined effects of
liquidity, assets management and debt management on operating result.
The Analysis of profitability of selected sampled researcher has taken two
basic ratios.
A. Margin ratio
B. Return ratio
[A] Margin Ratio:
The margin ratio reflects relationship between profit margin and total sales. It
measures the efficiency of company operations and this can also compared with
previous result also as well as also compared their competitors. The margin ratio
represents the firm‘s ability to translate sales in to profits at various stages of
measurement. A high margin ratio is a sign of good margin.
125
3.3.1 Gross profit margin ratio
The relationship between gross profit and sales shows by the gross profit
margin ratio. The first profitability ratio in relation to sales is the gross margin ratio. It
is calculated simply as a gross margin ratio. It is calculated to dividing the gross profit
by the sales.
Gross Profit Margin = Profit Before Depreciation Interact & Tax / Sales.
Gross Profit Margin = Gross Profit / Gross Sales.
The gross profit ratio shows exceed of sales over a production cost. Gross
profit margin is a good indication of how profitable a company is at the most
fundamental level, how efficiently a company uses its resources, materials and labour
our. PBDIT to gross sales reflects the efficiency with which management produces
each unit of product. This ratio show profits relative to sales after the deduction of
production costs, and indicate the relation between production costs and selling price.
The higher gross profit margin of firm relative to the industry implies that he
firm is able to produce at relatively lower cost. A higher gross profit margin ratio is a
sign of sound management.
A low gross profit margin may reflect higher cost of goods sold due to the
firm inability to purchase raw materials at favorable firm, inefficient utilization of
plant and machinery or over investment in plant and machinery resulting in higher
cost of production. The ratio will also be low due to a fall in prices in the market. In
this situation selling product by the firm in an attempt to obtain large sales volume,
the cost of goods sold remain unchanged. The financial manager must be able to
detect the causes of falling gross margin and initiate action to improve the situation.
The following table shows gross profit margin of sampled units.
126
Table-3.3.1
Gross profit margin of sampled units [%]
Table 3.3.1 indicates the gross profit margin of sampled units of oil refineries
that indicates the relationship between profit before depreciation interest & tax and
sales. The data was for five years and six sampled oil refineries. For BPCL this ratio
was 3.49%, 2.92%, 3.56%, 2.96% and 2.50% for respective year 2007-08, 2008-09,
2009-10, 2010-11, and 2011-12. It means they show mix trend with the average of
3.08% and standard deviation was 0.44 for BPCL. Unfortunately last three year ratio
was continuously decline. That shows negative impact in relation to gross profit for
BPCL. For HPCL this ratio shows mix trend it was 2.48%, 2.87%, 3.65%, 3.27%, and
2.99% for the year 2007-08, 2008-09, 2009-10, 2010-11 and 2011-12 respectively.
For IOC was also show mix trend respect to gross profit margin. It was fluctuate
between 2.48 to 3.65 in year 2007-08 to 2009-10. The Average value of this ratio was
4.50 and standard deviation was 1.41 for IOC during study period. For MRLP this
ratio was 6.05 in year 2007-08, 5.46 in year 2008-09, 6.06 in year 2009-10, 5.05 in
year2010-1, 3.43 in year 2011-12 was 5.21 and 1.09 standard deviation for MRPL.
FOR NRL this ratio shows mix trend during study period. The ratio likewise,
in 2007-08 - 6.69, in 2008-09 - 5.44, in 2009-10 - 6.50, in 2010-11 - 6.86, 2011-12 -
6.86, and 2011-12 - 3.68. However last year of the study period ratio was decline 50%
approximately. For CPCL ratio indicate decline trend excluding year 2007-08.
However in year 2008-09 ratio was stand in negative. It means higher operating
management cost over a sales. For management of CPCL need conscious about
decline trend regards to gross profit. Their mean and S.D was 2.89 and 2.66

average value of all the units year wise. The year wise trend also shows mix trend
during entire study period but it was decline in last three years and stand to 2.72% in
year 2011-12. from 4.97% in year 2009-10.

Figure 3.3.1 shows that BPCL and HPCL are not stable in study period. Much
fluctuate in the study period. It shows whether sales or cost of production are not
stable. In case of IOC ratio also goes to more up and down. However last three year
ratio was decline up 200% and stand to 3% from the 6.35% for the MRPL and NRL
ratio was highest compare to other selected refineries. Unfortunately in the last year
ratio was decline in both MRPL and NRL. CPCL ratio was step fall goes to less than
one in year 2008-09. After that ratio increased and stand to 3.72 in year 2009-10.
Unfortunely in the last year one again ratio was declining due to higher production
cost and lower sales. So finance manager must be needed to detect the reasons for
falling of gross profit margin ratio.
Result of hypothesis:-
H0:- There is no significant difference on gross profit margin ratio between all
selected units under study period.
H1:- There is a significant difference on gross profit margin ratio between all
selected units under study period.
128
From the table 3.3.1, the calculated value of F-test is 4.00 and F- limit is 2.62
(5% level of significance). The F-ratio is higher than the F- limit. It indicates that the
null hypothesis is rejected and alternative hypothesis accepted. To conclude there is
significant difference on gross profit margin between all selected sampled units. Thus
gross profit generating capacity of all sample units remains not same under study
period.
3.3.2 Operating profit margin ratio
Operating activity is a main working portion of the every firm. So this purpose
measuring operating efficiency of firm has essentials. The net operating profit margin
ratio is a yardstick of operating efficiency. Many factors are affected to them so it
should be used cautiously. The affected factor is such as external uncontrollable
factors, internal factors, employees and managerial efficiency etc. all of which are
different to analysis. The operating profit ratio defined to dividing EBIT by the sales.
Operating profit margin = EBIT / Sales.
The ratio is destroyed to focus attention in the net profit margin ratio arising
from business operation before interest and tax. This ratio measures the efficiency of
operation of the company. This ratio compared with the previous years and with that
competitors to determine the trend in operating profit margins of the company and its
performance in the industry. This measure will depict the correct trend of
performance where there is erratic fluctuation in the operating policy from year to
year.
The analyzed gross profit ratio and net profit ratio are jointly than analysis and
interpretation of the firms about profitability more meaning full. Net profit margin
will decline unless operating expenses decrease significantly.
The argument is that both are the ratio should be analyzed and each time of
expenses should be thoroughly investment to find out the causes of decline any or
both ratios.
129
The variation can occur due to several factors such as:
a) Changes in sales prices.
b) Changes in the demand for the product.
c) Changes in the administrative or scaling expenses.
d) Changes in the proportionate shares of sales of different products with
varying gross margins.
A drawback is that the percentage which results varies depending on the
sources employed to finance business activity, interest is changed ― above the line ‖
while dividends are deducted ― below the line ‖. The following table shows the
operating profit ratio and overall trend of operating profit of sampled units.
Table-3.3.2
Operating profit margin of sample unit [%]
Table:-3.3.2 shows the operating profit margin of sample units. This ratio
shows that operating efficiency in term of return with the relationship to sales. For
BPCL operating profit margin ratio continuously decline (Excluding year 2009-10)
under study period. Reason for declining ratio that is high operating cost compared to
sales. For HPCL this ratio was 1.56, 2.13, 2.64, 2.28 and 1.78 in year 2007-08, 2008-
09, 2009-10, 2010-11 and 2011-12 respectively. The mean value this ratio was 2.08 it
is also very low. So during study period operating activity of HPCL was not
satisfactory for IOC this ratio stand big floating trend. The lowest value of ratio was

1.96 in the year 2011-12 and highest value of ratio was 5.24 with the mean of 3.43
and standard deviation 1.36. For MRPL ratio was indicate mix trend. The ratio was
5.04, 4.57, 5.75, 4.16, and 2.67 for the year 2008-09 to 2011-12 respectively.
However ratio was decline last three year and in year 2011-12 ratio was decline up to
200%. For NRL average value of this ratio was 1.48%. In year 2009-10 ratio was
increased up to 6.43% from 3.78% in previous year but after that ratio was decline
continuously. So it is negative sign for NRL. Looking to the numerical fact of
operating profit margin ratio of CPCL, the operating profit of CPCL was not
satisfactory. In the year 2009-10 ratio goes to negative. After that they recovered and
stand to positive figure but trend was continuously decline. So management of CPCL
need to causes about this critical situation, looking to the average value, ratio between
years under study period. The value was 4.44% and 4.50% for MRPL and NRL it
was highest compared to other. Moderate level performance in case of IOC. For
BPCL, CPCL, and HPCL operating profit ratio was lower and it was not satisfactory
compared to other unit of oil refineries. The overall trend so year wise performance
units. The year 2009-10 performance of oil refineries was increase in operating
activity but after that continuously decline under study period.
Figure 3.3.2
Operating profit margin ratio of sampled units
Figure 3.3.2 indicates that in BPCL operating profit was not stable they
increase mid off study period after that decline. For HPCL rising initially three year
131
but after that ratio was decline. For IOC operating profit was quit fluctuate they goes
more up and more down under study period. But last three ratios was decline in case
of IOC. The MRPL and NRL the operating profit was not stable. In mid year of the
study period ratio was increased. In case of CPCL figure shows that the operating
profit decline and year 2008-09 below zero means in negative. But after that increased
and continuously decline. Looking to figure for all the selected oil refineries operating
profit of all the refineries was downstream under study period.
Result of hypothesis:-
H0:- There is no significant difference on operating profit margin ratio between
all selected units under study period.
H1:- There is a significant difference on operating profit margin ratio between all
selected units under study period.
From the table 3.3.2, the calculated value of F-test is 3.21and limit is 2.62 (5%
level of significance). The F-ratio is higher than the F-limit. It indicates that the null
hypothesis is rejected and alternative hypothesis accepted. To conclude there is
significant difference on gross profit margin between all selected sampled units. Thus
all the sample units are different in terms of operating profit generating capacity under
study period.
3.3.3 Net profit margin ratio
Net profit is obtained when operating expenses, interest and taxes are
subtracted from the gross profit. The net profit margin ratio is measured by dividing
profit after tax by sales.
Net profit margin = Profit after Tax (PAT) / Sales.
The profit after tax figures excludes interest on borrowing, interest is tax
deductible and therefore a firm which pays more interest pays less tax.
Net profit margin ratio established a relationship between net profit and gross
sales indicates management efficiency in manufacturing, administering and selling
products. This ratio is overall measure of the firm`s ability to turn each rupee sales
132
into net profit. If net profit is inadequate than the firm will fail to achieve satisfactory
return on shareholder funds.
The firm‘s capacity to with stand in adverse economic condition depend
on significance of this ratio. A firm with a high net margin ratio would be in an
advantageous position to survive in the face of filling selling prices, rising costs of
production or declining demand for the product. It would really be difficult for a low
net profit firm to with stand these adversities. Similarly a firm with high better use of
favorable conditions such as rising selling prices, falling costs of production or
increasing demand for the product. The following table indicates net profit margin
ratio of selected sample companies.
Table-3.3.3
Net profit margin of sample unit [%]
Table: - 3.3.3 shows net profit margin ratio of selected oil refineries. The ratio
shows relationship between net profit and net sales. For BPCL this ratio was 1.29,
0.51, 1.17, 0.95 and 0.59 for the year 2008-09 to 2011-12 respectively. The ratio show
fluctuating trend during all study period and decline trend in last three year of the
period. For HPCL ratio was stable in initial two year but after that ratio was increased
up 1.31%. However last three year of study ratio was much flat under study period.
The ratio was 2.57, 0.89, 3.51, 3.51, 2.08 and 0.85 for the year 2007-08 to 2011-12. In
the year 2011-12 ratio was blow one need o take initiate steps for IOC. For MRPL

For CPCL ratio indicate negative trend under study period. In the year 2007-
08 ratio was 3.39 but next year 2008-09 ratio come down up to -1.08 mean companies
in cared losses this year. However in the year 2009-10 and stable in positive ratio
during the remaining study period. According average value of net profit margin ratio
in the form of %, NRL stand to 1st rank due to low operating and financial cost
compared to sales and HPCL stand to last rank due to high cost compared to sales.
According to overall trend year wise performance of all selected oil refineries shows
mix trend. Unfortunately last three year net profit figure continuously decline for all
the selected all refineries.
Figure 3.3.3
Net profit margin ratio of sampled units
Figure 3.3.2 shows that BPCL net profit is very much fluctuate during study.
For HPCL increased first three year and after that continuously decline and last year
they reduce approximately twice in compared to previous year. In case of IOC net
profit position satisfactory at reasonable level but in year 2008-09 and 2011-12 they
lower than one. For MRPL net profit position shows mix trend with higher level
compare to other refineries. However they decline in last three year. For NRL net
134
profit position was very good because of low cost compared to sales. It is good sign
for management of NRL. For CPCL net profit figure shows that the first year net
profit was satisfactory but after that suddenly decline and make a loss in 2009-10. But
after that they recovered in next year and suffer with the profit under study period.
Result of hypothesis:-
H0:- There is no significant difference on net profit margin ratio between all
selected units under study period.
H1:- There is a significant difference on net profit margin ratio between all
selected units under study period.
From the table 3.3.3, the calculated value of F-test is 7.45 and limit is 2.60
(5% level of significance). The F-ratio is higher than the F- limit. It indicates that the
null hypothesis is rejected and alternative hypothesis accepted. To conclude there is
significant differences on gross profit margin between all selected sampled units. In
the terms of net profit all the sampled units are different.
3.3.4 Cash flow margin ratio
The cash flow margin ratio is an important ratio as it expresses the relationship
between cash generated, from operations and sales. The company needs cash to pay
dividends, suppliers, service debt, and invest in new capital assets, so cash is just as
important as profit to business firm.
The cash flow margin ratio measures the ability of a firm to translate sales into
cash the formula of cash flow margin ratio given below:
Cash flow margin = Cash flow from operating activities*100/Net sales
The numerator of the equation comes from the firm`s statement of cash flows.
The larger the percentage of cash flow margin shows effective cash generated position
from operations. Operating activities are the principal revenue producing activities
operating or financing activities operating activities include cash effect of those
transactions and events that enter into the determination of net profit or loss. The
following table no indicates cash flow margin ratio of sampled companies.
135
Table-3.3.4
Cash flow margin of sample unit [%]
Table 3.3.4 indicates cash flow margin ratio of sampled units. The shows
capacity of firm for converting to cash from sales for BPCL cash generating capacity
shows mix trend. The ratio shows negative sign in the year 2009-10 and also
increased up to 4.63 in year 2009-09 with the mean of 1.40 under study period. For
HPCL cash flow margin shows mix trend under study period. The ratio was 0.82%,
4.67%, 3.06%, 0.75% and 0.86% in the year 2007-08 to 2011-12. Their mean and
standard deviation was 2.03 and 1.77 respectively. For IOC cash generating capacity
was very much critical excluding in year 2009-10 and 2011-12 ratio shows negative.
There for IOC need to focus on cash flow margin. The cash generating capacity of
MRPL was very good compare to other because increasing trend in initially. For NRL
cash generating from sales was not satisfactory because ratio stand below one
excluding the year 2011-12, and mean value also only 1.13. For CPCL cash flow
margin ratio much fluctuates because they increase and decrease suddenly. The
overall trend shows year wise performance of selected refineries. The overall trend
shows mix trend under study period. In the year 2010-11 cash converting capacity
from sales was satisfactory. The mean shows performance of refineries under study
period. The mean value was 4.47 in MRPL and lowest value was -1.12 in IOC. The
IOC need to focus on this cash generating capacity from the sales.

Figure 3.3.4 indicates BPCL cash generating capacity was not stable. In case
of HPCL, cash generating capacity was not stable the trend up at higher point in year
2009-10. For IOC cash generating capacity was very much poor. The ratios indicate
negative sign in two year initially after that they recovered but once again they go to
negative. However last year stable and indicate in positive sign. The MRPL cash flow
margin ratio indicates higher capacity compare to other sample units. However in last
year come down below zero. For NRL also this ratio not give satisfactory result. O nly
one year 2010-11 ratio was up-word but next down to negative. For CPCL also this
ratio not stable. Overall they stable in positive part excluding year 2009-10.
Result of hypothesis:-
H0:- There is no significant difference on cash flow margin ratio between all
selected units under study period.
H1:- There is a significant difference on cash flow margin ratio between all
selected units under study period.
From the table 3.3.4, the calculated value of F-test is 1.42 and limit is 2.62
(5% level of significance). The F-ratio is lower than the F- limit. It indicates that the
null hypothesis is accepted and alternative hypothesis rejected. To conclude there is
no significant difference on gross profit margin between all selected sampled units.
Thus cash flow margin ratio of all sample units remains same under study period.

3.3.5 Operating Expense ratio
There are many expenses ratios, such as factory expenses to sales,
administrative expenses to sales, sales expense to sales, or any other individual
expense(advertisement expense, commission, fuel, and soon) to sales. All these ratios
when calculated and compared either with the same ratios of the previous user or
some standard ratios determined by the management. Give a very important indication
whether these expenses in relation to sales are increasing or decreasing or stationary,
which in turn reflect the profit earning capacity of the concern firm. With increasing
sales, if the management can limit these operating expenses, it indicates the efficiency
of management in improving the operating efficiency of the company. The lower the
ratio, the greater is the profitability. Sometimes all operating expenses are added and
compared with the sales. This ratio is called operating expense ratio:-
The formulae of these ratios are as follows:-
I. Factory expense to sales ratio = Factory expenses * 100 /sales
II. Administration expenses to Sales ratio = Administration expenses * 100/ sales
III. Selling and distribution expenses to Sales ratio = Selling and distribution
expenses * 100 /sales

The table 3.3.5 shows operating expense ratio of sample units. The ratio shows
operating efficiency of units. Higher expenses ratio shows negative sign. For BPCL
ratio shows minor mix trend. This ratio was 4.41%, 4.40%, 5.49%, 5.22% and 4.73%
for year 2008,2009,2010,2011 and 2012 respectively. The mean also 4.85 mean close
to variable value. For HPCL also this ratio shows mix stable situation it mean no more
fluctuate, higher value of ratio was 5.84 and lower value was 4.11 with the mean and
standard deviation 5.85 and 0.69 respectively. For IOC this ratio was stable instantly
two year after that ratio shows decline trend. The ratio was 5.99, 5.94, 7.14, 6.93, and
5.73 for year 2008-09 to 2011-12 respectively. For MRPL operating expenses ratio
quite low and in the year 2008-09 ratio come down below one it shows higher level of
operating efficiency in curtaining operating expense. For NRL this ratio was 3.89,
4.51, 5.22, 8.69, and 7.55 for the year 2008-09 to 2011-12 respectively. The ratio
shows continuously increased trend for four year after that they decline it shows
positive signals. For CPCL ratio shows mixture trend but they not more fluctuate they
fluctuate between 2 and 2.5 only. The mean and standard deviation was 2.44 and 0.36
respectively.
The overall trend year wise performance of operating expenses ratio of
Sample Company shows mix trend. The operating expenses condition of BPCL and
HPCL was same because same mean value. For NRL mean value was 5.97 mean
much higher management need to take corrective action for this higher expense for
MRPL operating exp was lower. So it shows good management regarding operating
activities.
Figure 3.3.5
Operating Expense ratio of sampled units
139
Figure 3.3.5 indicates that the for BPCL operating expenses ratio was stable in
first two years after that they increased and once again they decline up to previous
stable. In case of HPCL also same position happens for this ratio. For IOC this ratio
was not stable under study period. But they stand higher position due to certain reason
like higher administrative and salary cost. For MRPL figure trend show mixture trend
at lower level compare to other sampled units. It shows satisfactory position related to
operating efficiency. For NRL ratio trend shows upward up to year 2010-11. However
in year 2011-12 ratios come down is a sign for management. For CPCL ratio shows
stable position excluding the year 2009-10. But due to this level operating expenses
company incurred losses in certain year. So required to reduce operating expenses for
better profitability.
Result of hypothesis:-
H0:- There is no significant difference on operating expense ratio between all
selected units under study period.
H1:- There is a significant difference on operating expense ratio between all
selected units under study period.
From the table 3.3.5, the calculated value of F-test is 13.93 and limit is 2.62
(5% level of significance). The F-ratio is higher than the F- limit. It indicates that the
null hypothesis is rejected and alternative hypothesis accepted. To conclude there is
significant difference on gross profit margin between all selected sampled units. Thus
in all the units are differently work in the terms of factory, administrative and selling
expenses margin ratio.
[B] Return Ratio:
The strategic aim of a business enterprise is to earn a return on capital. If in
any particular case, the return in the long term is not satisfactory than the deficiency
should be corrected. The return ratio should be calculated for measuring the historical
performance of an investment centre called for a compression of the profit that has
been earned with capital employed.
140
3.3.6 Return on fixed Assets
Return on assets is a financial ratio that shows the percentage of profit that a
company earns in relation to its fixed Assets. The ratio shows ability of earning in
from investment in fixed Assets.
This ratio is computed to know the productivity of the fixed assets. This ratio
is calculated as follows:
Return on fixed Assets= Profit after tax*100 / Fixed Assets
The profitability of the firm is measured by establishing relation of net profit
which is also called profit after tax with the fixed assets of the organization. This ratio
is indicates the efficiency of utilization of assets in generating revenue.
Table-3.3.6
Return of fixed Assets of sampled units
The table 3.3.6 shows the return of fixed assets of selected sample units. The
data has been given for five year and six selected oil refineries. The mean shows unit
wise performance and overall trend shows year wise performance under study period.
For BPCL return on fixed assets shows mix trend. This ratio has been 7.15%, 2.39%,
5.41%, 5.44% and 4.58% for the year 2007-08 to 2011-12 respectively. The mean
value is lower compare to similar units IOC. So BPCL need to take a some corrective
action for this utilization of fixed assets. For HPCL also this ratio shows mixture
trend. In the year 2008-09 and 2011-12 ratios has been only 1.86% and 2.55%

respectively. The mean was value also lower at 3.46%. So these show not satisfactory
utilization of assets in HPCL. For IOC this ratio much fluctuate and ratio varies
between 3.45% to 11.98% in the year 2008-09 and 2011-12. It means management of
IOC not constant on effective utilization of fixed assets. Compare to BPCL and IOC
mean value has been higher at 7.78%. The MRPL show satisfactory performance with
the 18.04% mean and 7.90 standard deviation unfortunately ratio shows continuously
downstream performance. In case of NRL also this ratio shows mix trend. In the year
2011-12 ratio was only 8.33% lower under study period. Need to take corrective
action to management of NRL. For CPCL this ratio shows mixture trend. In the year
2008-09 ratio goes to negative but after that company take a some measure and once
again goes to positive. Unfortunately in year 2011-12 once again ratio was down up to
1.28%. Looking to the overall trend utilization of fixed assets of sample units shows
downstream in last three year.
Figure 3.3.6
Return on fixed assets of sampled units
Figure 3.3.6 shows for BPCL and HPCL, trend of return on fixed assets
movement in same direction under study period. The HPCL curve down side compare
to BPCL. For IOC this ratio trend much fluatuate not to stable. The last three year
trend continusly downword and last year decline approximatel 50% compare to
previous year. For MRPL this ratio take a higher position compare all other selected

units but curve shows decresing trend under study period. In case of NRL also curve
movement in up and down. For CPCL this ratio curve decline up below zero mean
nagative in year 2008-09. However last three year curve shows decresing movement.
Looking to the overall figure of utilization of fixed assets,among the three big units
IOC stand to first rank and among the remaining three units MRPL stand to firs t rank.
Result of hypothesis:-
H0:- There is no significant difference on return on fixed assets of sample units
between all selected units under study period.
H1:- There is a significant difference on return on fixed assets of sample units
between all selected units under study period.
From the table 3.3.1, the calculated value of F-test is 2.14 and limit is 2.62
(5% level of significance). The F-ratio is lower than the F- limit. It indicates that the
null hypothesis is accepted and alternative hypothesis rejected. To conclude there is
no significant difference on gross profit margin between all selected sampled units.
Thus utilization of fixed assets is same for all the sampled units.
3.3.7 Return on net worth
This ratio known as return on shareholders‘ funds. Return on shareholders‘
funds is very effective measure of the profitability of an enterprise. These ratios
measure the return on the total equity of the shareholders. It should be compared with
the ratios of other similar companies to determine whether the rate of return is
attractive. In fact, this ratio is one of the most important relationships in financial
statement analysis. It shows the ratio of net-profit to owner‘s equity.
Return on net worth = Net profit after tax & interest *100/ shareholders fund
This ratio strongly depends on many factors such as industry, economic
environment (inflation, macroeconomic risks etc…) the higher this ratio shows the
better financial performance of the company. The DuPont analysis shows higher ratio,
higher financial leverage and higher financial leverage dangerous for company
solvency.

Table-3.3.7
Return on net worth of sampled units (%)
The table 3.3.7 shows return on net worth of sample units. The ratio shows
relationship between shareholders earning and their investment. For BPCL ratio show
mixture trend under study period but decline trend in last three year. The ratio has
been in last three year 11.74%, 10.99%, and 8.79% for year 2009-10, 2010-11 and
2011-12 respectively. For HPCL also shows mixture trend for this ratio. The ratio has
been 8.56% in year 2007-08, 5.35% in the 2008-09, and 11.25% in year 2009-10,
10.99% in the 2010-11, and in the year 2011-12. The value was 8.87 it is lower
compare to BPCL and IOC. For IOC ratio has been not owner‘s fund. The value of
mean and standard deviation was 12.83 and 6.02 respectively. It is higher compare to
two similar units HPCL and BPCL. For MRPL ratio was declining trend under study
period. Approximately ratio decline 200% compare to first year and last year o f study
period. The mean value was 21.86% and standard deviation 7.98. The higher mean
value compare to all selected units. For NRL ratio decline for initially three year after
that they increased in one year and once again ratio was decline an last year. The ratio
has been 16.58%, 10.20%, 9.64%, 10.76% and 6.81 for the year 2007-08 to 2011-12.
For NRL ratio was continuously downward trend (excluding the year 2011-12). With
the mode rate level mean value that was 10.80%. For CPCL net profit to owner equity
shows mix trend. In the year 2008-09 ratio was in negative, but positive in next year
and last three year continuously decline and in the year 2011-12 ratio was 1.61 only.
Under study period overall trend shows mix-movement and last three year decline
movement in return in net worth.

Result of hypothesis:-
H0:- There is no significant difference on return on net worth between all selected
units under study period.
H1:- There is a significant difference on return on net worth between all selected
units under study period.
From the table 3.3.7, the calculated value of F-test is 1.47 and limit is 2.62
(5% level of significance). The F-ratio is higher than the F- limit. It indicates that the
null hypothesis is accepted and alternative hypothesis rejected. To conclude there is
145
no significant difference on gross profit margin between a ll selected sampled units.
Thus, all the units get the same return from the share holders‘ fund.
3.3.8 Return on debt
The return on debt can be expressed as the quantification of a company
performance or net income as allied to the amount of debt issued by the compa ny.
Putting it other way the return on debt refers to amount of profit generated for every
rupees held by a company in debt. For compacting the return on debt following
formula can be used.
Return on Debt= Net Profit * 100 / Total Debt
Use the debt in capital structure it is skill because it is not commonly used
financial resources. The following table shows return on debt of sampled units.
Table-3.3.8
Return on debt of sampled units
Table:-3.3.8 indicates return on debt of selected units. The ratio shows net
profit relationship with debt. For BPCL this ratio has been mix trend. The ratio was
10.52%, 3.47%, 6.92%, 8.15% and 6.17% for the year 2007-08 to 2011-12. The mean
and standard deviation of this ratio was 7.05% and 2.59 respectively. For HPCL also
this ratio has been indicates mixture trend. The ratio was not much fluctuating under
study period. They variation take place between 2.52% to 6.11% only. The similar big

company BPCL and IOC mean value was lower mean for HPCL leverage not act as
positively compare to BPCL and IOC. In IOC last year‘s three ratios was decline
trend they show in efficiency of management for utilization of debt for last three year.
The mean value was 13.77% so capacity of net profit arising from the debt was
satisfactory for all the year under study period. For MRPL this ratio was very high
because MRPL use the lower debt in capital structure. The ratio was 61.81%, 60.02%,
65.57%, 75.055% and 15.79% for the year 2007-08 to 2011-12. The mean value has
been 55.75 % which was higher among the all selected units. For NRL return of debt
ratio was decline under study period. The ratio was decline approximately 400%
under study period. The mean and standard deviation has been 13.26% and 7.44
respectively. For CPCL this ratio was mix trend but in the year 2008-09 and 2011-12
ratios has been much lower. The trend was decline in last three year. The overall trend
shows mix trend and last year ratio was much lower mean utilization of debt was not
satisfactory for all selected units.
Figure 3.3.8
Return on debt of sampled units
The figure shows performance of selected units regard to return on debt. For
BPCL ratio was not stable. The start at higher level after that decline and last three
year fluctuate between two points. For HPCL also curve says return on debt position
was not stable under study period. For IOC this ratio was higher position in figure
compare to BPCL and HPCL. However last three years has been decline
147
approximately two-hundred percentage position compared all units. Approximately
stable in initially for year but in the fifth year much decline.
The NRL curve says debt utilization capacity was decline under study period.
For CPCL ratio was starting at higher but further that decline and goes to negative.
Looking to the overall figure MRPL stand higher position and HPCL stand lower
position.
Result of hypothesis:-
H0:- There is no significant difference on return on debt between all selected units
under study period.
H1:- There is a significant difference on return on debt between all selected units
under study period.
From the table 3.3.8, the calculated value of F-test is 9.69 and F - limit is 2.62
(5% level of significance). The F-ratio is higher than the F- limit. It indicates that the
null hypothesis is rejected and alternative hypothesis accepted. To conclude there is
significant difference on gross profit margin between all selected sampled units. Thus
utilization of debt is not same in terms of return for all the sampled units.
3.3.9 Return of Capital employed
This is the most important test of profitability of a business it measure the
overall profitability it is ascertained by comparing profit earned and capital employed
to earned it. It is also called as return on investment on capital employed. It indicates
percentage employed in the business. It is calculated on the basic of the following
formula:-
Return on capital employed= EBIT * 100 / Capital employed
The term capital employed has been given different meaning by different
accountants. One popular formula is as follows:
Equity share capital + preference share capital + reserve and other
undistributed profit + long term loan and debentures – fictitious assets –non operating
assets.
148
The term operating profit means profit before interest and tax. Thus the return
on capital employed is dependent upon net profit ratio and capital turnover ratio.
Table-3.3.9
Return on Capital employed of sampled units (%)
The table: - 3.3.9 indicates return of capital employed sampled units.
This ratio is very useful for measuring the utilization of capital, reserve and equity
and performance capital, reserve and long term debt. For BPCL this ratio shows
increasing trend excluding the year 2007-08. The mean and standard deviation show
lower rate increasing trend. For HPCL this ratio was minor fluctuate in last three year
and mixture trend in under study period. The ratio has been 19.61%, 12.78%, 12.39%,
12.49% for the year 2007-08 to 2011-12.
For IOC this ratio indicates mix trend. Considering last three year ratio shows
declining trend. The mean value is 15.24% shows higher level efficiency for
utilization of capacity compared to BPCL and HPCL. For MRPL this ratio shows
decreasing trend under study period. The ratio has been declining approximately
250% compare to first year and last year of study period. For NRL ratio shows
mixture movement under study period. The mean and standard deviation has been
15.60% and 3.14 respectively. For CPCL ratio has been shows mixture trend under
study period. In the year 2008-09 ratios have negative sign means company not get
return from the capital. However in the next year company remove this critical
situation gets 14.43% return from the employed capital. Looking to the mean MRPL
use the effective utilization of employed capital CPCL not use efficiency employed

The figure 3.3.9 indicates the BPCL upward trend in utilization of capital in
term of profit(Excluding first year of study period). For HPCL start at higher level but
after that curve decline and once again increasing and constant to reamining years of
study period. The curve position was below compare to BPCL means need to take
corrective action compare to competitors. For IOC figure says much mixture trend
under study period. Looking to the last three year movement was downstrem . in the
overall figure curve position was upper side compare to all unit in MRPL. But trend
was downword they says mismanegment was up-down under study period. For CPCL

3.3.10 Cash Return on Assets
The ratio shows cash generating capacity from the assets. The ratio shows
important role because many times cash and profit shows positive Correlation. The
cash return on assets is generally used only in more advanced profitability ratio
analysis. It is used as a comparison to return on assets since. It is cash cooperation to
this ratio as return on assets is stated on an accrual basis. The cash is required for
future investment so this ratio has been much important. The following formula can
be used for calculate ratio.
Cash return on Assets= cash flow from operating activity * 100/ Total Assets
The numerator is taken from the statement of cash flows and the denominator
from the balance sheet. The higher percentage is better.
Table-3.3.10
Cash return on assets of sampled units (%)
The table 3.3.10 show cash return on assets of sample units. For future
investment cash is required so this ratio is useful for measuring the future investment
capacity. For BPCL cash generating capacity from the assets was not stable. In the
year 2009-10 it is negative with the positive mean of 6.26. For HPCL also cash return

position from the assets was not stable. Excluding the year 2008-09 lower level
capacity of HPCL in this ratio. For IOC this ratio has been very poor. This ratio stand
to negative sing like -12.25%, -26.02%, -0.49%, 5.29%, -2.15% for the year 2007-08
to 2011-12. The mean values of IOC regard to cash generating from assets also
negative. For MRPL ratio shows increasing trend initially three year but after that
ratio has been decline and goes to negative at -5.07% in year 2011-12. For NRL this
ratio was lower and demising movement for initially three year but after that the
suddenly increased at 12.18% and 13.66% in year 2010-11 and 2011-12 respectively.
This situation says positive sign for the future investment. For CPCL compare to fixed
assets cash was generate at higher level. The mean value has been 22.53% which was
higher compare to all selected units. The overall movement says mixture trend under
study period.
Figure 3.3.10
Cash return on assets of sampled units
The figure 3.3.10, says cash generating capicity from the assets. For BPCL
ratio has been much mixture trend becouse their standard deviation was higher than
mean. For HPCL also ratio shows mixture trend under study period. For IOC curve
stand in negative side under period excluding the year 2010-11. In the negative side
ratio also mixture trend under study period. For MRPL curve stay in upper side in
figure compare to BPCL,HPCL and IOC and also increasing trend intially three year.
However in last year ratio goes to nagetive side. For NRl curve at lower side in
positive side intially three year but in the last two year suddenly increased at higher
level and also stable for the next year. For CPCL curve start at higher position but
then after suddenly decline and come down in negative side. Looking to overall
152
figure excluding HPCL and NRL all the sample units goes to nagetive side one or
more year under study period.
Result of hypothesis:-
H0:- There is no significant difference on cash return on assets between all
selected units under study period.
H1:- There is a significant difference on cash return on assets between all selected
units under study period.
From the table 3.3.10, the calculated value of F-test is 2.64 and limit is 2.62

null hypothesis is rejected and alternative hypothesis accepted. To conclude there is
significant difference on gross profit margin between all selected sampled units. Thus
cash generating capacity of all the sampled units are different.
3.4 Correlation between selected variable and ROI
This section of chapter shows simple correlation – coefficient analysis are
done between some selected ratios and return on investment (ROI). The ratios used
for the analysis are WCR (Working Capital Ratio), Acid test ratio, Total assets
turnover ratio, Investment turnover ratio and Debt- equity ratio. These ratios help us
to measure the overall performance and judge profitability of the companies. The
correlation shows impact of some selected ratio on ROI and also shows degree of
relationship between selected ratio and ROI.
