 3. EMPLOYEE STOCK OPTION SCHEME
 
 Dr. Reddy''s Employees Stock Option Plan-2002 (the DRL 2002 Plan): The
 Company instituted the DRL 2002 Plan for all eligible employees in
 pursuance of the special resolution approved by the shareholders in the
 Annual General Meeting held on 24 September 2001. The DRL 2002 Plan
 covers all employees of DRL and its subsidiaries and directors
 (excluding promoter directors) of DRL and its subsidiaries
 (collectively, eligible employees). Under the Scheme, the
 Compensation Committee of the Board (''the Committee'') shall administer
 the Scheme and grant stock options to eligible directors and employees
 of the Company and its subsidiaries. The Committee shall determine the
 employees eligible for receiving the options, the number of options to
 be granted, the exercise price, the vesting period and the exercise
 period. The vesting period is determined for the options issued on the
 date of the grant. The options issued under the DRL 2002 plan vests in
 periods ranging between one and four years and generally have a maximum
 contractual term of five years.
 
 The DRL 2002 Plan was amended on 28 July 2004 at the Annual General
 Meeting of shareholders to provide for stock options grants in two
 categories:
 
 Category A: 1,721,700 stock options out of the total of 2,295,478
 reserved for grant of options having an exercise price equal to the
 fair market value of the underlying equity shares on the date of grant;
 and
 
 category B: 573,778 stock options out of the total of 2,295,478
 reserved for grant of options having an exercise price equal to the par
 value of the underlying equity shares (i.e., Rs 5/- per option).
 
 The DRL 2002 Plan was further amended on 27 July 2005 at the Annual
 General Meeting of shareholders to provide for stock option grants in
 two categories:
 
 category a: 300,000 stock options out of the total of 2,295,478
 reserved for grant of options having an exercise price equal to the
 fair market value of the underlying equity shares on the date of grant;
 and
 
 category B: 1,995,478 stock options out of the total of 2,295,478
 reserved for grant of options having exercise price equal to the par
 value of the underlying equity shares (i.e., Rs 5/- per option).
 
 The fair market value of a share on each grant date falling under
 Category A above is defined as the average closing price (after
 adjustment of Bonus issue) for 30 days prior to the grant, in the stock
 exchange where there is highest trading volume during that period.
 Notwithstanding the foregoing, the Compensation Committee may, after
 getting the approval of the shareholders in the Annual General Meeting,
 grant options with a per share exercise price other than fair market
 value and par value of the equity shares.
 
 As the number of shares that an individual employee is entitled to
 receive and the price of the option are known at the grant date, the
 scheme is considered as a fixed grant.
 
 In the case of termination of employment, all unvested options would
 stand cancelled. Options that have vested but have not been exercised
 can be exercised within the time prescribed under each option agreement
 by the Committee or if no time limit is prescribed, within three months
 of the date of employment termination, failing which they would stand
 cancelled.
 
 During the current year, the Company under the DRL 2002 Plan has issued
 262,520 category B options to eligible employees. The vesting period
 for the options granted varies from 12 to 48 months.
 
 The Company instituted the DRL 2007 Plan for all eligible employees in
 pursuance of the special resolution approved by the shareholders in the
 Annual General Meeting held on 27 July 2005. The DRL 2007 Plan came
 into effect on approval of the board of Directors on 22 January 2007.
 The DRL 2007 Plan covers all employees of DRL and its subsidiaries and
 directors (excluding promoter directors) of DRL and its subsidiaries
 (collectively, eligible employees). Under the DRL 2007 Plan, the
 Compensation Committee of the Board (the Compensation Committee)
 shall administer the DRL 2007 Plan and grant stock options to eligible
 employees of the Company and its subsidiaries. The Compensation
 Committee shall determine the employees eligible for receiving the
 options, the number of options to be granted, the exercise price, the
 vesting period and the exercise period. The vesting period is
 determined for all options issued on the date of the grant. The options
 issued under the DRL 2007 plan vest in periods ranging between one and
 four years and generally have a maximum contractual term of five years.
 
 During the current year, the Company under the DRL 2007 Plan has issued
 56,060 options to eligible employees. The vesting period for the
 options granted varies from 12 to 48 months.
 
 4. : hedges of foreign currency risks and derivative financial
 instruments
 
 The Company is exposed to exchange rate risk which arises from its
 foreign exchange revenues and expenses, primarily in U.S. dollars,
 british pound sterling, Russian roubles and Euros, and foreign currency
 debt in U.S. dollars, Russian roubles and Euros.
 
 The Company uses forward contracts and option contracts (derivatives)
 to mitigate its risk of changes in foreign currency exchange rates.
 Further, the Company uses non-derivative financial instruments as part
 of its foreign currency exposure risk mitigation strategy.
 
 During the previous year ended 31 March 2011, the Company adopted the
 Accounting Standard (AS)-32 Financial Instruments: Disclosures as
 issued by ICAI, to the extent that the adoption does not conflict with
 existing mandatory accounting standards and other authoritative
 pronouncements, Company law and other regulatory requirements. The
 objective of this standard is to provide information relating to
 various financial instruments that the Company holds along with the
 nature and extent of risks arising from financial instruments to which
 the Company is exposed to. Further, the standard requires disclosure
 for the risk management strategies that management adopts to address
 the specific risk factors to the extent they are considered to be
 material.
 
 Hedges of highly probable forecasted transactions
 
 The Company classifies its derivative contracts that hedge foreign
 currency risk associated with highly probable forecasted transactions
 as cash flow hedges and measures them at fair value. The effective
 portion of such cash flow hedges is recorded as part of reserves and
 surplus within the Company''s hedging reserve, and re-classified in
 the statement of profit and loss as revenue in the period corresponding
 to the occurrence of the forecasted transactions. The ineffective
 portion is immediately recorded in the statement of profit and loss.
 
 The Company also designates certain non-derivative financial
 liabilities, such as foreign currency borrowings from banks, as hedging
 instruments for the hedge of foreign currency risk associated with
 highly probable forecasted transactions and, accordingly, applies cash
 flow hedge accounting for such relationships.  Re-measurement gain /
 loss on such non-derivative financial liabilities is recorded as part
 of reserves and surplus within the Company''s hedging reserve, and
 re-classified in the statement of profit and loss as revenue in the
 period corresponding to the occurrence of the forecasted transactions.
 
 In respect of the aforesaid hedges of highly probable forecasted
 transactions, the Company has recorded, in reserves and surplus, a net
 loss of Rs 28 and a net loss of Rs 242 for the years ended 31 March 2012
 and 2011, respectively. The Company also recorded, as part of revenue,
 a net loss of Rs 344 and a net gain of Rs 263 during the years ended 31
 March 2012 and 2011, respectively.
 
 The net carrying amount of the Company''s hedging reserve was a loss
 of Rs 3 as at 31 March 2012, as compared to a gain of Rs 25 as at 31
 March 2011.
 
 5. : HEDGES OF FOREIGN CURRENCY RiSKS AND DERIVATIVE FINANVIAL
 INSTRUMENTS (CONTINUED)
 
 Hedges of recognized assets and liabilities
 
 Changes in the fair value of derivative contracts that economically
 hedge monetary assets and liabilities in foreign currencies and for
 which no hedge accounting is applied are recognized in the statement of
 profit and loss. The changes in fair value of such derivative contracts
 as well as the foreign exchange gains and losses relating to the
 monetary items are recognized as part of foreign exchange gains and
 losses.
 
 Fair values of foreign exchange derivative contracts are determined
 under the Black Scholes Merton technique by using inputs from market
 observable data and other relevant terms of the contract with counter
 parties which are banks or financial institutions.
 
 In respect of the aforesaid foreign exchange derivative contracts and
 the ineffective portion of the derivative contracts designated as cash
 flow hedges, the Company has recorded, as part of foreign exchange
 gains and losses, a net loss of Rs 1,582 and a net gain of Rs 858 for the
 year ended 31 March 2012 and 2011, respectively.
 
 6. : FINANCIAL RISK MANAGEMENT
 
 The Company''s activities expose it to a variety of financial risks,
 including market risk, credit risk and liquidity risk. The Company''s
 primary risk management focus is to minimize potential adverse effects
 of market risk on its financial performance. The Company''s risk
 management assessment and policies and processes are established to
 identify and analyze the risks faced by the Company, to set appropriate
 risk limits and controls, and to monitor such risks and compliance with
 the same. Risk assessment and management policies and processes are
 reviewed regularly to reflect changes in market conditions and the
 Company''s activities. The Board of Directors and the Audit Committee
 are responsible for overseeing Company''s risk assessment and management
 policies and processes.
 
 a.  Credit risk
 
 Credit risk is the risk of financial loss to the Company if a customer
 or counterparty to a financial instrument fails to meet its contractual
 obligations, and arises principally from the Company''s receivables from
 customers. Credit risk is managed through credit approvals,
 establishing credit limits and continuously monitoring the credit
 worthiness of customers to which the Company grants credit terms in the
 normal course of business. The Company establishes an allowance for
 doubtful debts and impairment that represents its estimate of incurred
 losses in respect of trade and other receivables and investments.
 
 Trade and other receivables
 
 The Company''s exposure to credit risk is influenced mainly by the
 individual characteristics of each customer. The demographics of the
 customer, including the default risk of the industry and country, in
 which the customer operates, also has an influence on credit risk
 assessment. Credit risk is managed through credit approvals,
 establishing credit limits and continuously monitoring the
 creditworthiness of customers to which the Company grants credit terms
 in the normal course of business. As at 31 March 2012 and 31 March 2011
 the maximum exposure to credit risk in relation to trade and other
 receivables is Rs 19,435 and Rs 17,705 respectively (net of allowances).
 
 Financial assets that are neither past due nor impaired
 
 None of the Company''s cash equivalents, including time deposits with
 banks, are past due or impaired. Trade receivables amounting to Rs
 16,684 and Rs 14,196 were neither past due nor impaired as at 31 March
 2012 and 31 March 2011 respectively.
 
 Loans and advances
 
 Loans and advances are predominantly given to subsidiaries for the
 purpose of working capital and capital expansions; and the Company does
 not consider any significant exposure to credit risks associated with
 such financial assets.
 
 b.  Liquidity risk
 
 Liquidity risk is the risk that the Company will not be able to meet
 its financial obligations as they become due. The Company manages its
 liquidity risk by ensuring, as far as possible, that it will always
 have sufficient liquidity to meet its liabilities when due, under both
 normal and stressed conditions, without incurring unacceptable losses
 or risk to the Company''s reputation.
 
 As at 31 March 2012 and 2011, the Company had unutilized credit limits
 from banks of Rs 14,290 and Rs 13,089, respectively.
 
 As at 31 March 2012, the Company had working capital of Rs 18,614
 including cash and bank balances of Rs 8,490 and current investments of
 Rs 2,070.  As at 31 March 2011, the Company had working capital of Rs
 10,490, including cash and bank balances of Rs 662.
 
 Financial guarantees
 
 Financial guarantees disclosed in Note 2.24 have been provided as
 counter corporate guarantees to financial institutions and banks that
 have extended credits and other financial assistance to the Company''s
 subsidiaries. In this regard, the Company does not foresee any
 significant credit risk exposure.
 
 c.  Market risk
 
 Market risk is the risk that the fair value or future cash flows of a
 financial instrument may fluctuate because of change in market prices.
 Market risk may arise as a result of changes in the interest rates,
 foreign currency exchange rates and other market changes that affect
 market risk-sensitive instruments. Market risk is attributable to all
 market risk-sensitive financial instruments including foreign currency
 receivables and payables and long-term debt. The Company is exposed to
 market risk primarily related to foreign exchange rate risk, interest
 rate risk and the market value of its investments. Thus, the Company''s
 exposure to market risk is a function of investing and borrowing
 activities and revenue generating and operating activities in foreign
 currencies.
 
 Foreign exchange risk
 
 The Company''s exchange risk arises from its foreign operations, foreign
 currency revenues and expenses (primarily in U.S. dollars, british
 pound sterling and Euros) and foreign currency borrowings (in U.S.
 dollars, Euros and Roubles). A significant portion of the Company''s
 revenues are in these foreign currencies, while a significant portion
 of its costs are in Indian rupees. As a result, if the value of the
 Indian rupee appreciates relative to these foreign currencies, the
 Company''s financial performance gets adversely impacted. The exchange
 rate between the Indian rupee and these foreign currencies has changed
 substantially in recent periods and may continue to fluctuate
 substantially in the future. Consequently, the Company uses derivative
 financial instruments, such as foreign exchange forward and option
 contracts, to mitigate the risk of changes in foreign currency exchange
 rates in respect of its forecasted cash flows and trade receivables.
 
 The details in respect of the outstanding foreign exchange forward and
 option contracts are given in Note 2.35 above.
 
 In respect of the Company''s derivative contracts a 10%
 decrease/increase in the respective exchange rates of each of the
 currencies underlying such contracts would have resulted in an
 approximately Rs Nil increase/decrease in the Company''s hedging reserve
 and an approximately Rs 3,870 increase/decrease in the Company''s net
 profit as at 31 March 2012.
 
 In respect of the Company''s derivative contracts and non-derivative
 financial liabilities, a 10% decrease/increase in the respective
 exchange rates of each of the currencies underlying such contracts
 would have resulted in an approximately Rs 349 increase/decrease in the
 Company''s hedging reserve and an approximately Rs 1,014
 increase/decrease in the Company''s net profit as at 31 March 2011.
 
 (1) Others includee currencies such as Russian roubles, British pound
 sterlings, Australian dollars, Venezuela bolivars, etc.
 
 For the years ended 31 March 2012 and 2011, every 10%
 depreciation/appreciation in the exchange rate between the Indian rupee
 and the respective currencies in the above mentioned financial
 assets/liabilities would affect the Company''s net loss/profit by
 approximately Rs 652 and Rs 839 respectively.
 
 Interest rate risk
 
 As at 31 March 2012 and 31 March 2011, the Company had foreign currency
 loans of Rs 6,665 carrying a floating interest rate of LIBOR plus
 100-150 bps and Rs 5,758 carrying a floating interest rate of LIBOR plus
 52-80 bps respectively. Also as at 31 March 2011 the company had an INR
 loan of Rs 950 carrying an interest rate of 8.75%. Since these are short
 term loans, the Company does not consider any significant changes in
 the interest rates and hence, has not entered into any interest rate
 swaps to hedge its interest rate risk.
 
 For the years ended 31 March 2012 and 2011, every 10% increase or
 decrease in the floating interest rate component (i.e. LIBOR) of its
 short-term loans from banks would affect the Company''s net loss/profit
 by approximately Rs 5 and Rs 16, respectively.
 
 The Company''s investments in time deposits with banks and short-term
 liquid mutual funds are for short durations, and therefore do not
 expose the Company to significant interest rates risk.
 
 Commodity rate risk
 
 Exposure to market risk with respect to commodity prices primarily
 arises from the Company''s purchases and sales of active pharmaceutical
 ingredients, including the raw material components for such active
 pharmaceutical ingredients. These are commodity products, whose prices
 may fluctuate significantly over short periods of time. The prices of
 the Company''s raw materials generally fluctuate in line with commodity
 cycles, although the prices of raw materials used in the Company''s
 active pharmaceutical ingredients business are generally more volatile.
 Cost of raw materials forms the largest portion of the Company''s
 operating expenses. Commodity price risk exposure is evaluated and
 managed through operating procedures and sourcing policies. The Company
 has historically not entered into any derivative financial instruments
 or futures contracts to hedge exposure to fluctuations in commodity
 prices.
 
 7. : EMPLOYEE BENEFIT PLANS
 
 7.1 gratuity plan of dr. reddy''s laboratories limited
 
 In accordance with applicable Indian laws, the Company provides for
 gratuity, a defined benefit retirement plan (the Gratuity Plan)
 covering certain categories of employees in India. The Gratuity Plan
 provides a lump sum payment to vested employees at retirement or
 termination of employment. The amount of payment is based on the
 respective employee''s last drawn salary and the years of employment
 with the Company. Effective September 1, 1999, the Company established
 the Dr. Reddy''s Laboratories Gratuity Fund (the Gratuity Fund).
 Liabilities in respect of the Gratuity Plan are determined by an
 actuarial valuation, based upon which the Company makes contributions
 to the Gratuity Fund. Trustees administer the contributions made to the
 Gratuity Fund. Amounts contributed to the Gratuity Fund are invested in
 specific securities as mandated by law and generally consist of federal
 and state government bonds and debt instruments of Indian
 government-owned corporations.
 
 The following table sets out the status of the aforesaid funded
 gratuity plan as required under AS-15 (Revised):
 
 8. LONG SERVIVE AWARD BENEFIT PLAN of DR. REDDY''s LABORATORIES
 LIMITED
 
 During the year ended March 31, 2010, the Company introduced a new
 post-employment unfunded defined benefit plan under which all eligible
 employees of the Company who have completed the specified service
 tenure with the Company would be eligible for a Long Service Cash
 Award at the time of their employment separation. The amount of such
 cash payment would be based on the respective employee''s last drawn
 salary and the specified number of years of employment with the
 Company. Accordingly the Company has valued the liability through an
 independent actuary.
 
 discount rate: The discount rate is based on the prevailing market
 yields of Indian government securities as at the balance sheet date for
 the estimated term of the obligations.
 
 Salary Escalation rate: The estimate of future salary increases
 considered takes into account the inflation, seniority, promotion and
 other relevant factors.
 
 9. : DIVIDEND REMITTANCE IN FOREIGN CURRENCY
 
 The Company does not make any direct remittances of dividends in
 foreign currencies to American Depository Shares (ADS) holders. The
 Company remits the equivalent of the dividends payable to the ADS
 holders in Indian Rupees to the depositary bank, which is the
 registered shareholder on record for all owners of the Company''s ADS.
 The depositary bank purchases the foreign currencies and remits
 dividends to the ADS holders.
 
 10. : RESEARCH AND DEVELOPMENT ARRANGEMENTS
 
 I-VEN Pharma arrangement
 
 During the year ended 31 March 2005, the Company had entered into an
 agreement with I-VEN Pharma Capital Limited (I-VEN) for the joint
 development and commercialization of a portfolio of 36 generic drug
 products. As per the terms of the agreement, I-VEN has a right to fund
 up to 50% of the project costs (development, registration and legal
 costs) related to these products and the related U.S. Abbreviated New
 Drug Applications (ANDA) filed or to be filed, subject to a maximum
 contribution of U.S.$ 56 millions. Upon successful commercialization of
 these products, the Company is required to pay I-VEN a royalty on net
 sales at agreed rates for a period of 5 years from the date of
 commercialization of each product.
 
 As per the agreement, in April 2010 and upon successful achievement of
 certain performance milestones specified in the agreement (e.g.
 successful commercialization of a specified number of products, and
 achievement of specified sales milestones), I-VEN has a one-time right
 to require the Company to pay I-VEN a portfolio termination value
 amount for such portfolio of products. In the event I-VEN exercises
 this portfolio termination value option, then it will not be entitled
 to the sales-based royalty payment for the remaining contractual years.
 
 The Company and I-VEN reached an agreement to settle the portfolio
 termination value option available to I-VEN at a consideration of Rs
 2,680 to be paid by the Company.
 
 On 1 October 2010, the Company, DRL Investments Limited (a wholly owned
 subsidiary of Dr. Reddy''s) and I-VEN entered into an agreement
 regarding the medium of settlement for the portfolio termination value.
 Pursuant to such an arrangement, controlling interest in I-VEN was
 acquired by DRL Investments Limited; thereby making I-VEN a wholly
 owned subsidiary of the Company as of 1 October 2010. In connection
 with the transaction, the Company had advanced an amount of Rs 2,680 to
 DRL Investments Limited out of which an amount of Rs 2,549 is
 outstanding and disclosed as part of ''Long term loans and advances'' as
 of 31 March 2012.
 
 11. : ISSUANCE OF BONUS DEBENTURES
 
 Pursuant to a scheme of arrangement sanctioned by the High Court of
 Andhra Pradesh, Hyderabad, India on 19 July 2010 and subsequent
 approval of the Reserve Bank of India (on 18 January 2011) and
 no-objection from the Indian income-tax authorities (on 1 February
 2011), the Company had, on 24 March 2011, allotted 1,015,516,392, 9.25%
 Unsecured Redeemable Non-convertible Bonus Debentures (aggregating to Rs
 5,078) in the ratio of 6 debentures of the face value of Rs 5 each fully
 paid up for every equity share of Rs 5 each held as on the record date
 i.e. 18 March 2011. The interest is payable at the end of 12, 24 and 36
 months from the initial date of issuance. The bonus debentures are
 redeemable at the end of 36 months from the initial date of issuance.
 These debentures have been listed on the Bombay Stock Exchange Limited
 and National Stock Exchange of India Limited.
 
 In terms of the scheme, the Company delivered the aggregate value of
 the debentures to an on-shore escrow account of a merchant banker
 appointed by the Board of Directors. The merchant banker received the
 aforesaid amount in the escrow account for and on behalf of and in
 trust for the members entitled to receive the debentures as deemed
 dividend within the meaning of Section 2 (22) of the Income-tax Act,
 1961. The merchant banker had also immediately following the receipt of
 funds in the escrow account, for and on behalf of the members, paid by
 way of subscription for allotment of the requisite number of debentures
 issued under the scheme.
 
 During the previous year ended 31 March 2011, in terms of accounting
 treatment set out in the scheme, the issuance of the aforesaid
 debentures (with an aggregate face value of Rs 5,078) and the dividend
 distribution tax paid thereon (aggregating to Rs 843) had been reflected
 by transferring the corresponding amounts from the General Reserve of
 the Company and the costs associated in relation to the aforesaid
 scheme (primarily comprising directly attributable transaction costs
 aggregating to Rs 51) had been expensed along with a corresponding
 transfer from the General Reserve account.
 
 Pursuant to the scheme and as per the requirements of the Companies
 Act, 1956, the Company has also created a Debenture Redemption Reserve
 aggregating to Rs 867 and Rs 19 as at 31 March 2012 and 31 March 2011
 respectively.
 
 12. : PROVISION FOR OTHER THAN TEMPORARY DIMINUTION IN THE VALUE OF
 LONG TERM INVESTMENTS
 
 Investments include an investment of Rs 16,146 in Lacock Holdings
 Limited, Cyprus (''Lacock''), a wholly-owned subsidiary of the Company.
 The Company participates in the German generics business through
 step-down subsidiaries of Lacock, i.e. Reddy Holdings GmbH and
 betapharm Arzneimittel GmbH (''betapharm'').
 
 There have been significant changes in the German generics market such
 as decrease in the reference prices of products, increase in discounts
 offered to State Healthcare Insurance (SHI) funds, and announcement
 of a large competitive bidding sale process from several SHI funds in
 Germany, and more recently in the current year with the reference price
 cuts and announcement of large sales tender from other key SHI funds.
 
 In view of the above, Management has reassessed the value attributable
 to its investment in Lacock and based on future cash flows expected
 from the business (in Lacock), believes that there is a decline, other
 than temporary, in the value of investment. Accordingly, an amount of Rs
 2,100 has been recorded as provision for diminution in the value of
 investment during the year ended 31 March 2012.
 
 segment information
 
 In accordance with AS-17 Segment Reporting, segment information has
 been given in the consolidated financial statements of Dr. Reddy''s
 Laboratories Limited and therefore no separate disclosure on segment
 information is given in these financial statements.
 
 venezuela currency devaluation
 
 The Company''s Venezuela operations are conducted as an extension of the
 parent company. On 30 December 2010, the Foreign Exchange
 Administration Commission of Venezuela (commonly referred to as the
 CADIVI'') enacted a decree (exchange agreement No.14) to unify the
 official exchange rates at a single rate of 4.3 Venezuela Bolivars
 (VEB) per U.S.$ by abolishing the preferential rate of 2.6 VEB per
 U.S.$ effective from 1 January 2011.
 
 Further, on 13 January 2011, the CADIVI issued another decree to
 interpret the transitional requirements for the use of the new official
 exchange rate and described that if the following conditions were to be
 satisfied, the use of the pre-devaluation rate of 2.6 VEB per U.S.$
 would be permissible:
 
 - For fund repatriation - to the extent the CADIVI has issued
 approvals in the form of approvals of Autorizacion de Liquidacion de
 Divisas (''ALD'') and which have been sent to and received by the Banco
 Central de Venezuela by 31 December 2010;
 
 - For foreign currency acquisition - to the extent the CADIVI had
 issued an Authorization of Foreign Currency Acquisition (''AAD'') by 31
 December 2010 and the approval relates to imports for the health and
 food sectors or certain other specified purposes.
 
 Based on the authorizations received by the Company, and in light of
 the above announcements, the Company believes that it is eligible for
 the usage of the preferential rate of 2.6 VEB per U.S.$ in relation to
 some of its monetary items denominated in VEB as on 31 March 2011.
 Accordingly, those monetary items in the Company''s Venezuelan
 operations are translated into the reporting currency at the
 preferential rate of 2.6 VEB per U.S.$. as at 31 March 2011.
 
 13. : COMPARATIVE FIGURES
 
 On applicability of revised Schedule VI from current year, the Company
 has reclassified previous year figures to conform to this year''s
 classification. The adoption of revised Schedule VI does not impact
 recognition and measurement principles followed for preparation of the
 financial statements. However, it significantly impacts presentation
 and disclosures made in the financial statements, particularly
 presentation of Balance Sheet.
