1.15.1 Provisions

Provisions are recognized when the Company has a
present obligation as a result of a past event and it is
probable that the Company will be required to settle the
obligation and a reliable estimate can be made of the
amount of the obligation.

The amount recognized as a provision is the best
estimate of the consideration required to settle the
present obligation at the end of the reporting period,
taking into account all the relevant facts, the risks and
uncertainties surrounding the obligation. Provision
is measured using the present value of cash flows
estimated to settle the present obligation as on the
reporting date.

Provisions towards cost of unfinished committed
work program (CWP) or minimum work program (MWP)
committed by the Company for all joint venture blocks
are made when there is a present obligation on the basis
of available facts as at the end of the reporting period.

1.15.2 Decommissioning and restoration obligations

Liabilities towards costs relating to assets retirement
obligations are recognized when the Company has an
obligation to plug and abandon a well, dismantle and
remove a facility or an item of plant and to restore the
site on which it is located, and when a reliable estimate

of that liability can be made. Liabilities towards costs
relating to dismantling, abandoning and restoring well
sites, associated production facilities and plants are
recognized at the commencement of drilling a well
or when facilities and plants are installed, as the case
may be. The amount recognized is the present value of
the estimated future expenditure determined
considering the depth and the type of wells (testing
well, exploratory well, developed well etc.), facilities
and plants installed in accordance with local conditions
and requirements at current prices and escalated
using appropriate inflation rate till the expected date
of decommissioning and discounted using appropriate
risk-free discount rate.

An amount equivalent to the decommissioning liability
provision is recognized as part of the corresponding
PPE, CWIP or Exploration & Evaluation Asset (E&E) as
the case may be. The decommissioning cost in respect
of dry exploratory well is expensed off in the Statement
of Profit and Loss as exploratory well cost.

Provision for decommissioning cost in respect of assets
under joint operations is considered as per participating
interest of the Company on the basis of estimates
prepared by the operator.

Liability for decommissioning cost is updated annually at
current cost basedonlatest available technical assessment.
The unwinding of the discount is included as a finance
cost. Any change in the present value of the estimated
decommissioning provision other than unwinding of
discount is adjusted to decommissioning provision
and added to or deducted from the cost of the asset in
the current period and is considered for depreciation
(depletion) prospectively. In case, where the reversal of
decommissioning provision exceeds the corresponding
carrying value of the related assets, the excess amount is
recognized in the Statement of Profit and Loss.

The Company considers the impact of health, safety
and environmental legislation in estimating the
decommissioning liability.

The actual cost incurred on settlement of the obligation
is adjusted against the liability and the ultimate gain or
loss is recognized in the Statement of Profit and Loss,
when the designated oil / gas field or a group of oil/gas
fields cease to produce.

receivables, loan receivables, cash and bank
balances, other financial assets and receivables.

in fair value through other comprehensive income for
equity instruments (other than in subsidiaries, joint
ventures and associates) that are not held for trading.

difference between the asset's carrying amount and the
sum of the consideration received and receivable and
the cumulative gain or loss that had been recognized
in other comprehensive income and accumulated in
equity is recognized in profit or loss if such gain or loss
would have otherwise been recognized in profit or loss
on disposal of that financial asset.

The Company's exposures to interest rates on financial assets and financial liabilities are detailed in the liquidity risk
management Refer note 42.8.

42.5.1 Interest Rate Sensitivity Analysis

The sensitivity analysis below have been determined based on the exposure to interest rates for both derivatives
and non-derivative instruments at the end of the reporting period. The analysis is prepared based on the floating
interest rate assets and liabilities, assuming that the amount outstanding at the end of the reporting period was
outstanding for the whole year.

If interest rates had been 50 basis points higher/lower and all other variables were held constant, the
Company's:

Loan Taken

• Profit and Equity for the year ended March 31, 2026 would decrease/increase by ' 30.33 crores (for the year
ended March 31, 2025 : decrease/increase by ' 27.60 crores).

42.6 Price risk

The Company is exposed to equity price risks arising from equity investments in Indian Oil Corporation
Limited.

Exposure in mutual funds

The Company also manages surplus fund through investments in debt mutual fund plans regulated by Securities
Exchange Board of India (SEBI). The NAV declared by Asset Management Companies(AMC) has generally remained
constant on the mutual funds plan taken by the company. However, if the NAV of the fund is increased/decreased by
5%, the sensitivity analysis has been mentioned below:

• Profit and Equity for the year ended March 31, 2026 would increase/decrease by ' 6.40 crores (for the year
ended March 31, 2025 : decrease/increase by ' 15.37 crores).

42.6.1 Equity Price Sensitivity Analysis

The sensitivity analysis below have been determined based on the exposure to price risks at the end of the reporting
period.

If equity prices had been 5% higher/lower:

• Other comprehensive income and Equity for the year ended March 31, 2026 would increase/decrease by
' 431.48 crores (for the year ended March 31, 2025 would increase/decrease by ' 406.94 crores.)

42.7 Credit Risk Management

Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss
to the Company. The Company has adopted a policy of only dealing with creditworthy counterparties and obtaining
sufficient collateral security, wherever appropriate, as a means of mitigating the risk of financial loss from defaults.
The Company regularly monitors its counterparty limits by reviewing the outstanding balance and ageing of the
same.

The Company has a credit policy that is designed to ensure that consistent processes are in place to measure and
control credit risk. Credit risk is considered as part of the risk-reward balance of doing business. On entering into any
business contract the extent to which the arrangement exposes the Company to credit risk is considered.

42.8 Liquidity Risk Management

Liquidity risk is the risk that suitable sources of funding for the Company's business activities may not be
available.

The Company manages liquidity risk by monitoring its forecast and actual cash flows, maintaining adequate reserves
and by matching the maturity profiles of financial assets and liabilities.

42.8.1.1 The table below provides details regarding the contractual maturities of financial liabilities including
estimated interest payments as at March 31, 2026 :

Note 2 : Fair value on the basis of price provided by respective Insurance companies
Note 3 : Fair value on the basis of quoted price from NSE

42.9.2 Fair value of financial assets and financial liabilities that are not measured at fair value (but fair value
disclosures are required)

Except as detailed in the following table, the company considers that the carrying amounts of financial assets and
financial liabilities recognised in the financial statements approximate their fair values.

Fair value hierarchy

Level 1-Quoted prices(unadjusted) in active markets for identical assets or liabilities.

Level 2-Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either
directly (i.e. as prices) or indirectly (i.e. derived from prices).

The fair values of the financial assets and financial liabilities included in the level 2 categories above have been
determined in accordance with generally accepted pricing models based on a discounted cash flow analysis,
with the most significant inputs being the discount rate that reflects the credit risk of counterparties.

The Fair Value of current financial assets and current financial liabilities are approximately equals to their carrying
value.

There has been no transfer in either direction [i.e. between Level 1,2 and 3 ] for the year ended 31st March 2026 & 31st
March 2025

The Company has not classified any material financial instruments under Level 3 of the fair value hierarchy.

43.2 Defined Benefit Plans

The various Benefit Plans which are in operation in the Company are Oil India Limited Employees Provident
Fund (OILEPF), Oil India Limited Staff Provident Fund (OILSPF), Oil India Gratuity Fund (OIGF), Oil India
Employees' Pension Fund (OIEPF), Oil India Pension Fund (OIPF), Leave Encashment Fund, Post-Retirement
Medical Benefit and Social Security Scheme Fund. The present value of the obligation is determined based on
actuarial valuation using the Projected Unit Credit Method, which recognizes each period of service as giving
rise to additional unit of employee benefits entitlement and measures each unit separately to build up the final
obligation.

The amount recognized in the Balance Sheet as the present value of the defined benefit obligation is net of the fair
value of plan assets at the Balance Sheet date.

These plans typically expose the Company to actuarial risks such as: investment risk, interest rate risk, longevity
risk and salary risk.

LEASES

The Company has adopted Ind AS 116 "Leases" with effect from 1st April 2019 and has elected to apply modified
prospective transition approach to measure the right-to-use asset at an amount equal to the lease liability and
initial estimate of decommissioning obligation, if applicable at the date of transition.

The Company has applied Ind AS 116 to hiring contracts of vehicles, rigs, cranes, crawlers, compressors, buildings,
etc. to evaluate whether these contracts contain lease components. Based on the evaluation of the terms and
conditions of the contracts, the Company has evaluated the lease components of such contracts falling under the
purview of Ind AS 116. The lease contracts, with limited exceptions, are recognized in the financial statements by way
of right-of-use assets corresponding lease liabilities and initial estimate of decommissioning obligation. The lease
liabilities were measured at the present value of the remaining lease payment and discounted using Government of
India Bond rate.

i. Short term leases / Low-value assets: The Company has elected short term leases and low value assets leases
for recognition exemption in terms of Ind AS 116. The Company recognizes the lease rental payment associated
with short term leases and low value assets as expense in the Statement of Profit & Loss. During the year ended
31st March 2026, the expenditure charged to profit & loss statement in respect to short-term leases and low-value
assets are as below:

similar assets in similar economic environment with a similar end rate. The Government of India Bond rate has been
bucketed into 0-3 years, 3-5 years, 5-10 years and above 10 years to different lease contract falling in those periods.
The Company has applied a single discount rate to a portfolio of leases of similar assets in a similar economic
environment with a similar end date.

The contracts such as vehicle hiring, drilling rigs hiring, bundle service contracts, etc. involve a number of additional
services and components including personnel cost, maintenance, drilling related activities, consumables and other
items. In most of such contracts, the additional services/non-lease components constitute significant portion
of the overall contract value. Where the additional services/non-lease components are not separately priced,
the consideration paid has been allocated based on the relative stand-alone prices of the lease and non-lease
components.

Statement of Cash Flow

The Value in Use of producing/developing each field is estimated on the basis of proved and probable
reserves (2P). Where further development of the fields in the CGUs are under progress, expected cost of
future development is also considered while determining the value in use.

In assessing value in use, the estimated future cash flows from the continuing use of assets and from its
disposal at the end of its useful life are discounted to their present value by applying weighted average
cost of capital as discounting rate. (as at March 31st, 2026: 11.05 % and as at March 31st, 2025: 12.04 %).

57.8 Service Tax and GST on Royalty payment:

Service Tax demand was raised on the Company for the period March, 2016 to June, 2017 seeking to levy Service Tax
on Royalty paid on Crude Oil & Natural Gas under the Oil Fields (Regulation & Development) Act, 1948 for the States
of Assam, Arunachal Pradesh and Rajasthan. The Company has challenged the demand on various grounds by filing
writ petitions before different High Courts. However, pending adjudication of the Writs, the Company has deposited
under protest the entire Service Tax demand of ' 257.13 crore.

Goods and Services Tax (GST) was implemented w.e.f. 1st July, 2017 and as per the FAQs on Government Services issued by
CBIC, GST is payable on Royalty paid for assignment of right to use natural resources. However, based on a legal opinion
obtained by the Company, Service tax/GST is not payable on Royalty payable/paid under the Oil Fields (Regulation &
Development) Act, 1948. The Company has accordingly filed Writ Petitions in different High Courts challenging such levy.
Further, the Hon'ble Gauhati High Court, vide its interim order dated 2nd November, 2021 has granted stay on the GST
on royalty payments made by the Company in the State of Assam until further orders. Keeping in view the jurisdiction
of Gauhati High Court, the Company has submitted a representation to GST Department, Arunachal Pradesh and the
payment of gSt on this account in the state of Arunachal Pradesh is presently on hold.

The total GST amount deposited under protest till 31st March 2026 is ' 1264.45 crore. Further out of the above-
mentioned amount the Company has received refund of ' 24.42 crore in the State of Assam.

All pending cases of the Company before Gauhati High Court and Rajasthan High Court were transferred to Hon'ble
Supreme Court for hearing by the Nine Judge Constitution Bench. However, Hon'ble Supreme Court vide its order dated
14th March 2024 has de-tagged the cases from the civil appeals Nos. 4056-4064/1999. The Hon'ble Supreme Court vide
its order dated 25.07.2024 on a similar case under the Mines and Minerals (Development and Regulation) Act (MMDR Act)
has, inter-alia, stated that royalty paid under MMDR Act is not a tax. However, the nature of royalty paid under Oilfields
(Regulation and Development) Act is to be decided by the Court separately as it has the distinct constitutional provision.

In view of the substantial time lapsed in litigating the matter, uncertainty involved in securing favourable decision
and accumulation of a huge amount, the Company had internally reviewed the matter and made a provision towards
Service Tax/ GST on royalty on the ground of prudence and conservative principle. The amount provided for the
quarter ending 31st March 2026 is ' 243.79 crore which includes an interest of ' 96.97 crore (' 865.12 crore including
interest of ' 360.42 crore for the twelve months ended 31st March 2026). The total amount provided on account of
disputed service tax/GST on royalty till 31st March 2026 is ' 4753.77 crore.

However, pending adjudication of the matter, the service tax /GST paid under protest has been/ being claimed as an
allowable deduction under the Income Tax Act, 1961.

57.9 Stamp duty and Registration charges of PML:

Revenue & DM Department, Government of Assam issued one Office Memorandum (OM) No. E-274398/2023/85
dated 1st September, 2023 on the process of determining the value of consideration for calculation of stamp duty
and registration fees for registering the deeds of Mining Leases of Oil, Natural Gas, Coal and other minerals including
renewal of the mining lease. At present stamp duty and registration charges of the PML areas are calculated and
paid based on dead rent. But the OM suggests to calculate the same on the basis of average annual royalty payable
over the lease period for the approved production quantity for the PML area instead of dead rent as it is not in
conformity with the statutory provisions under the Indian Stamp Act.

The change in methodology will have a significant impact on the amount of stamp duty and registration charges
which cannot be reliably ascertained. The Company is of the opinion that calculation of stamp duty and registration
charges on the basis of dead rent is in accordance with the provisions of the applicable Acts and Rules. The present
move to alter the basis and relate the same to estimated production over lease period appears contrary to the
provisions of the related Acts and Rules. The Company submitted its representation to the Government of Assam in
this regard. No demand notice has been received from the department concerned relating to any grant/renewal of
the PML areas of the Company.

Further, opinion from Additional Solicitor General of India (ASGI) was sought regarding validity of the above OM
issued by Government of Assam and ASGI in its opinion dated 24.12.2024 had clarified that the proviso to section
26 of Indian Stamp Act applies to a situation where the royalty is received as a rent or a part of the rent. However,
there is a special act, i.e., The Oil Field (Regulation and Development) Act, 1948 (ORDA) for regulation of oilfields
and payment of royalty. Rent would be payable regardless of whether the property is worked upon or not and is
not contingent on the discovery and production of crude oil & natural gas. On the other hand, the value of royalty
is always variable depending on the outcome of the production of mineral oil and therefore is always likely to be
indeterminate at the date of execution of the mining lease. Hence, he opined that section 26 of Indian Stamp Act is
not attracted to Petroleum Mining Lease and therefore inclusion of royalty for the purpose of calculation of stamp
duty is not justified and valid.

Accordingly in absence of any demand / clarity on the issue, the amount of firm liability or contingent liability arising
due to above OM issued by Government of Assam is unascertainable.

57.10 Special Additional Excise Duty (SAED):

Government of India (GoI) vide notification no. 05/2022 dated 30th June, 2022 had levied Special Additional Excise Duty
(SAED) on crude oil with effect from 1st July, 2022 which has been revised and notified by GoI from time to time. During
the current financial year, an amount of ' Nil (previous year ' 780.32 crore) related to SAED, calculated on the applicable
quantity excluding such quantity of crude oil produced by the Company which is in excess of crude oil produced during
the preceding financial year has been charged to Statement of Profit & Loss under head "Excise Duty".

57.11 Flaring of Natural Gas
