LIMITED REVIEW REPORT

The Board of Directors

Mahanagar Telephone Nigam Limited

We have reviewed the accompanying statement of unaudited financial results of Mahanagar Telephone Nigam Limited for the quarter/period ended December 31, 2011. This statement is the responsibility of the company's management and has been approved by the board of directors. Our responsibility is to issue a report on these financial statements based on our review.

We conducted our review in accordance with the Standard on Review Engagement (SRE) 2410 Engagements to Review Financial Statements issued by the Institute of Chartered Accountants of India. This standard requires that we plan and perform the review to obtain moderate assurance as to whether the financial statements are free of material misstatement. A review is limited primarily to inquiries of company personnel and analytical procedures applied to financial data and thus provide less assurance than an audit. We have not performed an audit and accordingly, we do not express an audit opinion.

We draw attention to the Para No. 2 of the Reviewed quarterly results pertaining to retirement benefits of the employees of the company which has been accounted for on the estimated basis considering the actuarial assumptions of previous year, the issue being technical, we have relied on the estimation provided by the company and managements' perceptions in this regard.

In view of this we are unable to comment on the adequacy or otherwise of these provisions.

Based on our review conducted as above, except the observations/matters mentioned in Annexure-I to this report, no other matter has come to our attention, that causes us to believe that the accompanying statement of unaudited financial results prepared in accordance with applicable accounting standards and other recognized accounting practices and policies has not disclosed the information required to be disclosed in terms of Clause 41 of the Listing Agreement including the manner in which it is to be disclosed, or that it contains any material misstatement.

ANNEXURE I TO LIMITED REVIEW REPORT

ANNEXED TO AND FORMING PART OF THE LIMITED REVIEW REPORT (Referred to in Para 4 of our report dated February 10, 2012

The company in its unaudited results for the quarter/period under review, has neither disclosed how the qualification made by the auditors in respect of previous accounting years/periods have been addressed and if the qualifications have not been resolved, the reasons therefore and the steps the company intends to take in such matters, nor it has given the impact of these qualifications on the unaudited results for the quarter/period under review, as required under the provisions of clause 41(iv)(c) of the Listing Agreement.

The License Fee to the DOT is being worked out on accrual basis as against the terms of License Agreements according to which the expenditure/deductions from the Gross Revenue are allowed on actual payment basis in respect of the Public Switching Telecom Network (PSTN) related call charges and roaming charges payable to BSNL and other service providers.

3.	The balances appearing in Advance Tax, Provisions for Income Tax and Interest on income Tax Refund are subject to confirmation of the Income Tax Department.

The company has not made payments of service tax on billings to BSNL after the Point of Taxation Rules 2011, which requires the payment of service tax on accrual basis with effect from July 1, 2011.Besides, the company has also not made payments of service tax payable on receipt basis in respect of sundry debtors as on 30.6.2011 in Delhi Unit, after the Point of Taxation Rules 2011 with effect from July 1, 2011.

The company has allocated the establishment overheads towards capital works on estimation basis. In view of the large amount getting allocated on capital projects vis a vis actual amount spent on these projects, the basis needs to be made more realistic and scientific and the same should avoid capitalizing the loss due to idle time of labour and machines. Moreover, in the absence of confirmation of the status / completion of WIP (work in progress), we cannot examine authenticity and accuracy of amounts outstanding and shown as WIP for extraordinary time period.

All the receivables and payables including amount receivable/payable to BSNL/DOT/ITI, Inter Unit Accounts and bank balances are subject to confirmation, reconciliation and consequent adjustments. In the case of BSNL, the bills raised for the use of infrastructure services are not accepted by them, hence we cannot comment on the recoverability of the said amount. The company is not making any provision for old outstanding balances from BSNL, DOT, Govt, agencies and other operators.

7.	The breakup of staff cost as made in reviewed financial results has been made by the management and relied upon by us.

8.	The accounting policy for making provisions for bad and doubtful debts pertaining to CDMA unit has not been revised from three years outstanding to six months' outstanding despite of the same being transferred from Basic to Cellular services.

9.	The loss on account of subscriber's instruments for WLL closed connections within last three years has not been ascertained and provided for.

10.

The company has sent material worth Rs.95.35 million to BSNL on barter basis for which corresponding material of Rs.2.45 Millions is only received from BSNL. As the transfer is in the nature of sales yet the same has not been shown as such and no sales tax has been charged by the company on such transfers.

11.	Based on the expert opinions, the company has not been deducting Tax at source on services received from BSNL. Also, the expenditure on account of Pension liability on the basis of actuarial valuation is considered as an allowable expense for the purpose of tax calculation.

12.

The provision for employee's benefits as per Accounting Standard 15 (Revised) and depreciation has been made on estimated basis. Pending actual determination of the liability/asset in this regard. The impact of the same on the results of the quarter is not ascertainable. Further, the liability on account of medical facilities to the retired employees has not been accounted for on actuarial basis rather the annual insurance premium paid for the policy for the purpose has been accounted for on year to year basis.

13.	The reconciliation of Subscribers' deposits, Sundry Debtors, Income from Recharge Coupons, ITC Cards, prepaid calling cards and stock of recharge coupons and leased circuits is under progress.

14.

The Company had accounted for Rs.3014.80 million during the previous year 2010-11, towards wet lease for infrastructure and other services provided in respect of Commonwealth Games of which Rs.430 million is subject to acceptance and final settlement. Besides, a claim of Rs.410 million has not been booked subject to final acceptance and settlement.
