In the event of liquidation of the Company, the holders of equity shares will be entitled to receive assets of the Company remaining after settlement of all liabilities. The distribution will be in proportion to the number of equity shares held by the shareholders.

(b) Aggregate number of shares issued for consideration other than cash during the period of five years immediately preceding the reporting date:

The Company has issued total 0.96 crore (31 March 2015: 1.46 crore) equity shares during the period of five years immediately preceding the reporting date on exercise of options granted under the employee stock option plan (ESOP scheme) wherein part consideration was received in form of employee services. No other equity shares have been issued for consideration other than cash during the period five years immediately preceding the end of current period.

(c) Aggregate number and class of shares bought back during the period of five years immediately preceding the reporting date:

The Company bought back 3.67 crore equity shares (31 March 2015 : 3.67 crore) during the period of five years immediately preceding the reporting date.

(d) Details of shareholders holding more than 5% shares in the Company

* The Company had bought back 3.34 crore equity shares during the previous year, prior to declaration of final dividend for FY 2013-14. Hence, accrual for final dividend of Rs, 21.73 crore and tax thereon Rs, 3.69 crore made during the FY 2013-14, on these shares, was reversed in the previous year.

*Due to fall in crude oil prices in the international market, the management is continuously reassessing its future strategy and is carrying on development and exploration only in regions where it believes that the reserves and resources are commercially viable. Accordingly, development and exploration activities have been suspended in certain fields and management has assessed the recoverable value of the entire oil and gas blocks to which they relate, being separate CGUs. The recoverable amounts have been determined based on the fair value less costs of disposal approach using the discounted cash fow technique, wherever the CGUs included some producing assets. For all other CGUs, where there are no oil and gas producing assets and activities have been suspended the recoverable amounts have been assessed as nil.

** represents Rs, 57.18 crore (31 March 2015: Rs, 399.65 crore) relating to oil and gas producing facilities and Rs, 569.85 crore (31 March 2015: Rs, 747.73 crore) relating to other tangible assets.

* CIHL holds interest in RJ-ON-90/1 oil and gas field, through a step down subsidiary. The Production Sharing Contract ('PSC') for the said field provides for an extension of the contract by a maximum period of ten years, in case there is a continued production of commercial natural gas from the said field. Since the management expects to continue with the production and sale of natural gas for a period of ten years even after the completion of the initial contract period, they believe that market participants would consider cash fows from the said asset for the said additional period of ten years as well without any modification in the term of PSC, and the same has been confirmed by independent legal opinions available with the Company. For the purpose of determining future cash fows from RJ-ON-90/1, the Company has used assumption for short-term (four years) oil price which scales up to US$ 70 per barrel by May 2020 as per consensus of various analyst recommendations. Thereafter, oil price has been escalating at a rate of 2.5% p.a.. The cash fows are discounted using the post-tax nominal discount rate of 11.00% and factors in the risks associated with the business including extension of the PSC, which is due for renewal in May 2020.

Basis the above valuation and also considering the fact that CIHL and its subsidiaries have other assets, the cumulative value of which exceeds

the carrying value of the investments, the Company believes that there is no long term diminution in the carrying value of its investments in

CIHL.

**The Company's investment in CMHPL was for funding the operations of an oil and gas block in Srilanka, held by CMHPL's step down subsidiary,

Cairn Lanka Private limited. Given the level of gas prices and fiscal terms, the development of hydrocarbons in the said block was not commercially

viable. Therefore, the value of the investment had been considered as permanently diminished in the previous year. The said subsidiary has

been transferred during the year.

In accordance with the provisions of Accounting Standard 22 'Accounting for taxes on income', the Company would have had deferred tax assets of Rs, 256.27 crore (31 March 2015: Rs, 144.02 crore) in respect of additional accumulated capital losses. However, as the management is not virtually certain of subsequent realization of the asset, the same has not been recognized in these financial statements.

Notes:

a) Recoverable from statutory authorities includes Rs, 30.00 crore (31 March 2015: Rs, 30.00 crore) on account of education and secondary and higher education cess paid for the financial year 2013-14, for which the Company has filed the refund applications pursuant to circular no 978/2/2014-CX issued by Central Board of Excise & Customs. The said refund applications have been rejected by the tax authorities, which have been appropriately challenged by the Company before Commissioner (Appeal), and also a writ petition has been filed before Honorable Rajasthan High Court.

b) Considering the current business plans, including production profiles, oil price forecast and management's expectation of an extension of the RJ-ON-90/1 PSC (refer note 10 above), the Company expects to recover the amount of MAT credit entitlement over its stipulated period of ten years from origination.

c) During the current year, the Company has utilized MAT credit aggregating to Rs, 251.72 crore (31 March 2015: Nil) which has been set off against provision for tax. This comprises of Rs, 250.60 crore shown as a current tax charge and Rs, 1.12 crore adjusted against General Reserve.

* Pursuant to the implementation of Schedule II of Companies Act 2013 on 1 April 2014, the Group had retrospectively changed the method of depreciation on some of its oil and gas assets from 'Straight Line' method to the 'Unit of Production' method. The additional charge of Rs, 1,046.39 crore due to the same for the period up to 31 March 2014 had been disclosed as an exceptional item for year ended 31 March 2015.

4. CONTINGENT LIABILITIES

a. Ravva Joint Venture Arbitration proceedings : Base Development Cost

Ravva joint venture had received the notice from Ministry of Petroleum & Natural Gas, Government of India (GOI) for the period from 2000-2005 for USD 129 million for an alleged underpayment of profit petroleum to the Indian Government, out of which, Group's share will be USD 29 million (approximately Rs, 192.34 crore) [31 March 2015: USD 29 million (approximately Rs, 181.65 crore)] plus potential interest at applicable rate (LIBOR plus 2% as per PSC).

This claim relates to the Indian Government's allegation that the Ravva JV had recovered costs in excess of the Base Development Costs ("BDC") cap imposed in the PSC and that the Ravva JV had also allowed these excess costs in the calculation of the Post Tax Rate of Return (PTRR). Joint venture partners initiated the arbitration proceedings and Arbitration Tribunal published the Award on 18 January 2011 at Kuala Lumpur, allowing claimants (including the Company) to recover the Development costs spent to the tune of USD 278 million and disallowed over run of USD 22.3 million spent in respect of BDC along with 50% legal costs reimbursable to the Joint venture partners. High Court of Kuala Lumpur dismissed Government of India's (GOI) application of setting aside the part of the Award on 30 August 2012 with costs. However, GOI appealed against the High Court's order before the Court of Appeal and the same has dismissed the GOI's appeal on 27 June 2014. GOI still preferred to challenge the same before the Federal Court, Kuala Lumpur and their Leave to Appeal is currently due for hearing before Federal Court on 17 May 2016. GOI has also issued Show

Cause Notice on this matter which the Company has replied to and also filed an application for enforcement of Award before Delhi High Court as an abundant caution. Next hearing is due on 29 April 2016. Furthermore, GOI is yet to agree on quantum of arbitration costs & expenses (legal fees and expenses) for reimbursing to the companies as per the Award. Therefore, the Companies have approached the Tribunal to quantify the costs. The GOI has obtained a stay order from Hon'ble High Court of Delhi,on 14 August 2015 against the Tribunal proceedings on quantum of arbitration costs on the grounds of Tribunal being functus offcio. Cairn has filed an appeal before the Hon'ble High Court of Delhi against the aforesaid 'stay order' granted by the Hon'ble High Court of Delhi against the Tribunal 'proceedings on determination of costs'. The matters are due for hearing on 3 October 2016 and 26 April 2016 respectively.

b. Ravva Joint Venture Arbitration proceedings: ONGC Carry

The Company is involved in a dispute with GOI relating to the calculation of payments that it was required to make in connection with the Ravva field. The Ravva PSC obliges the Company to pay proportional share of ONGC's exploration, development, production and contract costs in consideration for ONGC's payment of costs related to construction and other activities it conducted in Ravva prior to the effective date of the Ravva PSC (the ''ONGC Carry''). The question as to how the ONGC Carry is to be calculated, along with other issues, was submitted to an international arbitration panel in August 2002 which rendered a decision on the ONGC Carry in the Company's favour and four other issues in favour of GOI in October 2004 ("Partial Award"). The GOI filed a challenge to the ONGC Carry decision in the Malaysian courts, as Kuala Lumpur was the seat of the arbitration. The Federal Court of Malaysia which adjudicated the matter on 11 October 2011, upheld the Partial Award. Company persuaded with Ministry of Petroleum and Natural Gas (MoPNG) to implement the Partial Award while reconciling the statement of accounts as outlined in Partial Award ever since the Federal Court adjudication in place. However, MoPNG has issued a Show Cause Notice on 10 July 2014 alleging that profit petroleum has been short-paid. The Company had requested for Tribunal's reconstitution to publish the Final Award since it has retained the jurisdiction if parties are unable to agree on quantification sums due and payable to each other pursuant to the Partial Award. Accordingly, Tribunal was reconstituted and the next hearing is scheduled in June 2016. While the Company does not believe the GOI will be successful in its challenge, if the arbitral award is reversed and such reversal is binding, the Company could be liable for up to approximately USD 63.90 million (approximately Rs, 423.94 crore) [31 March 2015: USD 63.90 million (approximately Rs, 400.26 crore)] plus interest.

c. Service tax

"The Company has received ten show cause notices (SCN's) relating to the period 1 April 2006 to 31 March 2015, citing non-payment of service tax on various services. Out of ten SCN 's, nine SCN's have been adjudicated by the department relating to the period 1 April 2006 to 31 March 2014 for which the Company has filed an appeal. Further, with respect to the last SCN, relating to the period 1 April 2014 to 31 March 2015, Company is in the process of fling the reply.

Should future adjudication go against the Company, it will be liable to pay service tax of approximately Rs,49.53 crore ( 31 March 2015: Rs, 119.41 crore) plus potential interest of approximately Rs, 68.55 crore (31 March 2015: Rs, 132.70 crore), although this could be recovered in part, where it relates to services provided to Joint Venture of which the Company is operator.

d. Tax holiday on gas production

Section 80-IB (9) of the Income Tax Act, 1961 allows the deduction of 100% of profits from the commercial production or refning of mineral oil. The term 'mineral oil' is not defined but has always been understood to refer to both oil and gas, either separately or collectively.

The 2008 Indian Finance Bill appeared to remove this deduction by stating [without amending section 80-IB (9)] that "for the purpose of section 80-IB (9), the term 'mineral oil' does not include petroleum and natural gas, unlike in other sections of the Act". Subsequent announcements by the Finance Minister and the Ministry of Petroleum and Natural Gas have confrmed that tax holiday would be available on production of crude oil but have continued to exclude gas.

The Company filed a writ petition to the Gujarat High Court in December 2008 challenging the restriction of section 80-IB to the production of oil. Gujarat High Court did not admit the writ petition on the ground that the matter needs to be first decided by lower tax authorities. A Special Leave Petition has been filed before Supreme Court against the decision of Gujarat High court. However in an another similar case, the Gujarat High Court has held that tax holiday benefit would extend to production of gas.

In the event this challenge is unsuccessful, the potential liability for tax and related interest on tax holiday claimed on gas is approximately Rs, 279.64 crore (31 March 2015: Rs, 263.35 crore).

e. Withholding tax on payments made on acquiring a subsidiary

In March 2014 the Company received a notice from the Indian Tax Authorities (""Tax Authorities"") alleging failure by the Company to withhold tax on the consideration paid to Cairn UK Holdings Limited ("CUHL") in the year 2006-07, the then holding company. The said transaction relates to the acquisition of the shares of Cairn India Holdings Limited ("CIHL"), a 100% subsidiary of the Company, from CUHL during the financial year 2006-2007 as a part of group reorganization by the then ultimate parent company Cairn Energy Plc. Based upon the retrospective amendment(s) made in the year 2012 by inserting explanation 5 of section 9(1)(i) of the Income Tax Act, 1961, the Tax Authorities vide its order dated 11 March 2015, have raised a demand of approx. Rs, 20,494.73 crore (comprising tax of approx. Rs, 10,247.36 crore and interest of an equivalent amount) for not withholding tax on the consideration paid to CUHL, for acquiring shares of CIHL. Tax Authorities have stated in the said order that a short term capital gain of Rs, 24,503.50 crore accrued to CUHL on transfer of the shares of CIHL to the Company in financial year 2006-2007, on which tax should have been withheld by the Company. The Company understands that a tax demand has also been raised by the Tax Authorities on CUHL with respect to taxability of alleged capital gain earned by CUHL.

In this regard, Vedanta Resources Plc. filed a Notice of Claim against the Government Of India under the UK-India Bilateral Investment Treaty (the "BIT") in order to protect its legal position and shareholder interests. Management has been advised that Vedanta Resources Plc. has a good case to defend as per provisions of BIT, the benefit of which would ultimately accrue to the Company.

Further, the Company has been advised that there could be no liability on the Company on account of not withholding the taxes in the year 2006-07 based on provisions of law prevailing at the time of transaction as the aforesaid retrospective amendment has cast an impossible obligation on the Company to deduct tax by having to predict and anticipate that the retrospective amendment will be made by legislature on a future date. The Company has approached the Hon'ble Delhi High Court against the said order and also filed an appeal before the Commissioner of Income Tax

(Appeals) to defend its said position.

f. Others

i) Pursuant to the provisions of the Rajasthan Entry Tax Act, 1999, an entry tax demand has been raised for Rs, 24.66 crore (31 March 2015: Rs, 5.93 crore) plus penalty and interest which the Company has contested before appellate authorities. The Company believes that this levy is not constitutionally valid and its Special Leave Petition in this regard is pending before the Honorable Supreme Court.

ii) Other claims raised by contractors and vendors of the Group Rs, 24.56 crore (31 March 2015: Rs, 32.51 crore)

Based on an analysis of the legal positions, the management is of the view that the liabilities in the cases mentioned in (a) to (f) above are not probable and accordingly no provision has been considered necessary there against.
