The document discusses unit based costing (UBC) implemented at Hindustan Petroleum Corporation Ltd. UBC accumulates overhead costs for different organizational units and then assigns costs to products/services based on their use of activities in each unit. The key units considered are Fuel Refinery, Lube Refinery, and Captive Power Plant. UBC aims to provide more accurate product cost estimates for management decision making compared to traditional cost accounting. It involves identifying overhead costs like utilities, employee costs, maintenance etc. and allocating them to units based on cost drivers.

Hindustan Petroleum Corporation Ltd.
2. To support compliance with financial reporting requirements.
Typically, costs are allocated for either valuation purposes (i.e.,
financial statements for external users) or decision-making
purposes (i.e., internal uses) or both.
Traditional cost accounting system is often articulated with its
general ledger system
1) Accumulate costs within a production or non-production
department;
2) Allocate non-production department costs to production
department costs;
3) Allocate the resulting (revised) production department costs
to various products, services, or customers.

Note: - Cost Derived from this traditional approach suffer from several defects
that can result in distorted costs for decision-making purposes. For example if in
a refinery, a unit is sitting idle than also the cost incurred by that unit will be
allocated to the different products produced by refinery.
4. In order to remedy such distortions, many companies have adopted a different
cost-allocation approach called ACTIVITY-BASED COSTING (ABC).
In retrospect with traditional cost-accounting system,
1. The ABC accumulates overheads cost for different organizational activity, and
2. Then assign the cost to the products, services or customers (cost objects)
causing that activity.
3. Thus it helps in measure of cost of different activities and resources and then
individually assigning their effects on the costs of making a product or
providing a service.
5. •Cost of a product is the sum of the costs of all activities required to manufacture and deliver the
product.
•Products do not consume costs directly
•Money is spent on activities
•Activities are consumed by product/services
•ABC assigns Costs to Products by tracing expenses to “activities”. Each Product is charged based on
the extent to which it used an activity
•The primary objective of ABC is to assign costs that reflect/mirror the physical dynamics of the
business Provides ways of assigning the costs of indirect support resources to activities, business
processes, customers, products.
•It recognizes that many organizational resources are required not for physical production of units of
product but to provide a broad array of support activities.

7. Current Methodology
• At present the costing done by Mumbai Refinery is absorption costing
cum unit costing.
• The units taken into consideration into here are divided on the basis
of final product.
• The two units which are taken into consideration are Lube Refinery
and Fuel Refinery.
• Then the apportioned ratio of different products are attached to
different cost heads.
8. Steps Involved
The apportioning of different product ratio is obtained by taking into
consideration Sales realization, production and sales value of
production. The ratio is obtained by multiplying sales value of realization
(Per MT) and Total production of that particular product in a period and
dividing it by total sales value of realization.
The weightage is obtained by: -
Sales value of Production/Total Sales Value of Production = Weightage
STEP 1
Note: Sales Value of Production = Production*Sales Realization (Per MT) and
Sales Realization (Per MT) = Sales Realization (Total)/Sales Quantity (Per MT)
9. Steps Involved (Continued…)
In this step the cost is calculated on a whole, under different
overheads. In particulars the cost is accumulated on total. This table is
generated Under Para 5 of cost audit. The cost of different particulars
are based on the actual entries under different sub-sections of general
diary. In calculating costs no assumption is taken. Record for these are
maintained by the finance department in the form of TRIAL BALANCE.
STEP 2
10. Steps Involved (Continued…)
In the second step for assigning cost, these calculated weighted average cost
from the sales value of production are used. The Cost of Sales is calculated
for individual products by assigning these apportions/ratios for different cost
incurred during the process. Each Individual cost is assigned these ratios and
then accordingly the cost is calculated for different products. The Refinery is
divided into two Units. Two separate trial balances are made and Henceforth
these apportions are assigned values.

11. Short Comings Of Traditional Cost Accounting
An organization often has no clue about the origin and creation of the
company costs, nor are most particularly concerned about who
implemented the costing strategy. If employees only knew that a better
costing method could save a ton of money, as well as impress the boss
enough to earn that cozy corner office, then they would surely be more
excited. Many companies and many live in the dark ages; they often
use pricing models that were developed decades ago and were never
updated.
NOTE: - When asked with a company how they came up with their pricing methods, the answer is
usually ‘someone who worked here 15 years ago developed it and he’s no longer here’.
12. Unit Based Costing
The accounting performed for this project is based on the Activity
Based Costing. In this different units are taken into considerations and
overhead or indirect costs for these units is calculated. The costs taken
into consideration are some where actual as accounted by different
departments and at some places hypothetical based on a valid and
technically sound apportion done by taking various factors into
consideration.
13. The units taken into consideration are: -
1) Fuel Refinery*
2) Lube Refinery*
3) DHDS
4) Fuel Refinery-Boiler House
5) GFEC
6) Captive Power plant
7) OM&S
8) IETP
9) Lab
10) DHDS-Revamp
11) DHT
Note: -
1) FR consists of 10 units
2) LR consists of 6 Units
3) DHDS Revamp is
modified DHDS
Note: -
The implementation of this costing can be done for
taking management decision to improve efficiency
and ultimately resulting in higher GRM or Gross
Refinery Margin. The implementation of this project
for management decision is covered during later
stages.
14. Goals of Unit Based Costing
Although the general goals of each Units may differ, but Unit wise
cost accounting systems will generally try to satisfy three goals:
• To allocate certain period costs to products so that
financial statements can be prepared monthly, quarterly,
and annually
• To provide process control information to cost center
managers
• To provide product cost estimates to product and
business managers
15. Goals of Unit Based Costing (Continued…)
• First, financial statements are obviously an essential aspect of
illustrating an organization’s yearly operations, expenses, and
revenue. UBC’s goal is to better enhance the reliability of the
financial statements for a proper representation of the yearly
production expenses.
• Second, cost managers rely on the UBC information to provide
detailed information regarding processes and how they affect the
organization.
• Third, product managers are in need of very accurate product cost
estimates. These estimates are generally much more reliable with
an UBC method rather than a traditional cost method.
16. Steps Involved in UBC’s: -
Basic step Involved in UBC’s is accurate data and therefore success of
UBC is highly dependent on accuracy of data available. The more
accurate the data, the more accurate costs. These costs can then be
taken into consideration for process optimization. The Overheads
accounts for a massive 1900 Crores in Mumbai refinery alone.
17. The costs considered as overhead costs
are:-
1. Process Materials/Chemicals
2. Utilities
a) Power
b) Steam
c) Water
3. Direct Employees Expenses
4. Direct Expenses
5. Consumables stores and spares
6. Repairs and Maintenance
7. Quality Control
8. Technical Knowhow
9. Depreciation/Amortization
10. Other Production Overheads
18. The various Overheads: -
• Process Materials/Chemicals: - Process material and chemicals accounts as an
important cost in the refining of petroleum products. The revenue budget
sheet is used as an approximation ratio for calculating costs for the year 2013-
14.
• Utilities: -Utilities costs contain three sub-heads of Power, Steam and water in
its subsection. Utilities are basically the energy consumed by different units in
order to process the crude.
• Direct Employee Cost: - Direct employees cost contains salary and employee
benefits paid to the employee in a given year. The logic behind calculating the
ratio for direct employee ratio was based on the number of employee working
is a given unit. Then this number was multiplied with the average employee
cost incurred for the period 2013-14.
19. The various Overheads (Continued) : -
• Direct Expenses: - Direct expenses accounted for 275,310,501.95 Rs in the year
2013-14. It is very small when compared to other expenses but for the success of
Unit Based Costing that not even the smaller costs are left accounted and they are
also allocated under differ unit heads.
• Consumable Stores and Spares: - The expense for consumable stores and Spares
for the year 2013-14 was nil. Therefore they are making no changes in the overall
cost for the year 2013-14.
• Repairs and maintenance: - Repairs and maintenance form an important part for
FR, LR and CPP. The values of repair and maintenance are actual values and they
are the record maintained by the Maintenance department.
• Quality and Control Expenses: -Approximately 7.2 Million Metric Ton of Crude was
converted in 29+ products in the year 2013-14 in Mumbai Refinery of HPCL. The
apportioning of QC is done by taking the process and chemicals overhead as base
ratio.
20. The various Overheads (Continued) : -
• Technical Knowhow: - There was no cost incurred in the FY 2013-14 for technical
Knowhow. Technical Knowhow is basically for the services of the technology
rendered.
• Depreciation/Amortization: - Depreciation and amortization is done on the straight
line method in HPCL-MR. The values taken into consideration for this overhead is on
actual basis. Project finance department keeps track record of all the depreciated
and amortized assets
• Other Production Overheads: -All other production over head are calculated in this
heading. The rationale behind finding the ratio for this overhead is taking
cumulative average of the ratio of all the other overhead and then assigning these
values to the total cost incurred in this sub-head.

21. Application of Unit Based Costing: -
Application of Unit Based Costing: -
There are two broad purposes for using management accounting information:
●Strategic cost management—to determine the right things to do, i.e., selecting
the correct processes, suppliers, products, channels, and customers.
●Operational cost management—to perform well on those things identified as
strategic, improve productivity, and remove waste.
